The exhalation air/ respiratory air containing respiratory drop lets passes three stages for removal/ killing of microbes. The exhalation valve, the electric microbes killer units, the connection pipes, the exhaust fan/ fan/ air pump/ blower/ negative pressure generator, the microbes chemically killing/ decomposing system, the UV-C lamp system and the exhaust fan/ fan/ air pump/ blower/ negative pressure generator are fluidly connected in such a way that exhalation air passed through them removing/ killing microbes including SARS - CoV- 2 or any other influenza virus or any other virus during this process and finally to the atmosphere.

3. BACKGROUND OF THE INVENTION

Respirators are devices used by wearers to protect them from unhealthy atmospheres contains fumes, dangerous gases, dusts, air borne micro organism, biological warfare, unhealthy chemicals, radio active dusts etc. The main type of respirators are elastomeric half face piece respirators, elastomeric full face piece respirators, filtering face piece respirators, powered air-purifying respirators, powered air purifying respirators, supplied air respirators, semi-contained breathing apparatus, combination respirator, electronic breath filtration respirator etc. Respirator is used to protect the wearer from inhaling air borne pollutants and toxic gases. Filters/ cartridges used to filter air borne pollutants and toxic gases and filtered air is inhaled by the wearer.

None of the respirators available in the market can kill microbes e.g. bacteria, influenza virus like SARS - CoV-2 virus etc. available in the exhalation air/ respiratory droplets and respiratory air. Due to unavailability of such respirator human lives have been at risk for many centuries due to lethal unwanted attack by new and novel corona virus including SARS-CoV-2 virus or influenza virus or microbes etc.

The present invention the Aexpirator is designed, developed, thought of and invented to kill and/ or weaken power/ strength of microbes including not only SARS - CoV- 2 virus but also any other influenza viruses to infect human beings and protect the non wearers of the aexpirator from such deadly microbes from wearer of the aexpirator of infected persons.

4. SUMMARY OF THE INVENTION

As embodied and broadly described herein, the invention seeks to provide a system capable of killing microbes including novel corona viruses e.g. SARS-CoV-2 virus. There are three embodiments disclosed in the present invention Aexpirator which are developed for use by human beings as well as a separate device to clean the air from microbes including SARS-CoV-2 viruses or any other influenza viruses or microbes.

Various embodiments of the present invention Aexpirator are thought of and developed and described to meet the requirement of having an aexpirator mask with mask connected to a exhalation valve connected to a IR proximity sensor system or any other proximity sensor, an electric microbes killer unit and to a hose in the exhalation air path and in the inhalation air path the mask is connected to an inhalation non return valve/ check valve connected to a cartridge having filters and an electric microbes killer unit in one of the preferred embodiment, the hose is connected to an electric microbes killer assembly connected to a connection pipe connected to an exhaust fan or a fan or a blower or an air pump or a negative air pressure generator assembly connected to a chemical microbes killer system kept inside an exhalation air cleaning system or microbes killer and decomposing unit having also a tank for chemical storage and automatic supply system connected to a connection pipe connected to a UV - C lamp system connected to a connection pipe connected to an exhaust fan or a fan or a blower or an air pump or a negative air pressure generator unit connected to the atmosphere for discharge of exhaled air.

The electric power supply to the IR proximity sensor, the electric microbes killer units, the exhaust fan or fan or blower or air pump or negative air pressure generator is given from their battery available in a box or housing (103). The box (103) also contain zapper circuits or any other arrangement for providing enough voltage to the electric microbes killer unit to kill or weaken microbes strength/ power passing through the electric microbes killer units.

The exhalation air killing system or microbes killer and decomposing unit (D), the UV-C lamp system (E), the exhaust fan or fan or blower or air pump or negative air pressure generator unit (F), the box or housing (103) and the box or housing (146) are fixed on a waist belt (133) wear by the wearer.

When the wearer of the aexpirator exhaled, the IR proximity sensor start the exhaust fan or fan or blower or air pump or negative air pressure generator (48a) through a relay and when the wearer inhaled the IR proximity sensor stop the exhaust fan or fan or blower or air pump or negative air pressure generator (48a) through the relay. This cycle repeats each time.

The exhaled air or respiratory droplets passes through the exhalation valve, the microbes killer units, the exhaust fan or fan or blower or air pump or negative air pressure generator (48a), the chemical killer system/ unit, the UV-C lamp system and to the exhaust fan or fan or blower or air pump or negative air pressure generator unit (F) and finally to the atmosphere. During this process the microbes available in the respiratory droplets get killed or weaken their strengths/ power before delivery to the atmosphere. Thus infected person wearing the aexpirator can not deliver microbes to the atmosphere to infect other persons.

The inhaled air also passes through the electric microbes killer units and filters before being inhaled.

The aexpiartor mask is also designed in such a way that the wearer feels comfortable while speaking also in addition to easily inhaling and exhaling air for long period of times.

In the prior art none of the above features are available.

In normal position the flap (93) touches the circular edge/ opening (25”) and no air enters the face mask (A) from the exhalation valve (25). When the Aexpirator is worn by a wearer and the wearer exhaled air the air passed through the exhalation valve body (25’) and the circular edge (25”) and lift the flap (93) and the exhaled air go out side of the face mask (A). When inhalation is started the bottom surface of the flap (93) touches the circular edge (25”) and stop inward flow of the air flow from the exhalation valve (25) to inner side of the face mask (A). Thus the exhalation valve (25) acts like a non return valve. It allows air to flow in one direction only.

There is one stopper (16) attached in the housing (3). The stopper (16) is covered with a cap (16’) as shown in the Fig.1 , Fig.3 and Fig.4. The function of the stopper (16) is to restrict movement of the exhalation valve flap and lever mechanism (N) such that the flap (93) is away from the circular opening (25”) and the plate (95) is inserted in the rectangular box (92e’) and making the fan (48a) working continuously and allowing the exhalation valve (25) to be opened always.

IR sensor box (M) for IR sensor system (110) or any other sensor system to detect opening/ closing of exhalation valve (25) of the present invention Aexpirator is described in the Fig.13 (b).

The IR proximity sensor (110), the IR sensor box (M) and the fan (48a) and their control circuit and power supply arrangement is described in Fig. - 13 and Fig. - 20. The IR sensor box (M) is a rectangular box fitted with air tight two end covers (92a) and (92b) in the opposite open ends in the rectangular housing (92) and having the rectangular opening (92e) in the top surface for allowing back and forth or reciprocating movement of the plate (95) inside it. The rectangular tube (92e’) is kept inside the housing (92) and its top open end/ edge is fixed to the opening (92e) and is air tight. The opening (92e) is open from top end and other end is closed. The opening is basically a rectangular box (92e’) in the box (M) with one end closed and other end open and pneumatically insulated from the IR sensor (113) and IR LED (114) kept inside the box (M). The tubes (92d’) fitted in opposite sides (92i) and (92h) of the housing (92) of the box (M). The tubes (92d’) is partially inserted and air tight/sealed fitted in a circular hole in opposite end face (92i) and (92h). The tube (92d’) is having plane outer surface near closed end and threaded outer surface near open end. The end caps (92d) and (92c) on the opposite side and co axial are having the hole (92g) is fitted in the male threaded end of the tubes (92d’) in the opposite side walls of the housing (92). There are four locking groves (92f) at bottom edges. There are four locks (2d) extruded from the surface (2”) and matching with the locking grooves (92f) in the housing (92).

The IR sensor (113) is fitted in tube (92d’) and the IR LED (114) is fitted in tube (92d’) in axial line inside the IR sensor box (M) in opposite faces as shown in the Fig 13. The IR sensor (113) and the IR LED (114) of the IR proximity sensor (110) faces each other. The box (M) is having arrangement for fitting the IR sensor (113) and the IR LED (114) or any other proximity sensor having signal emitting and sensing devices.

The arrangement for holding these IR sensor (113) and IR LED (114) is such that they are fixed inside the box (M) and not allowable to change their position. They are sturdily fixed but can be easily maintained and removed if required inside the box (M) and do not disturb with respect to movement of the wearer. Cables connecting two terminals of the IR sensor (113) and cables connecting two terminals of IR LED (114) are taken out through the hole (92g) in the cap (92c) and the cap (92d) respectively of the housing/ tubes (92d’) respectively and the caps (92c) and (92d) are air tight screwed in threaded end of the tubes (92d’). The holes (92g) is sealed with sealing materials so that no air can enter inside the tubes (92d’). So the IR sensor (113) and IR LED (114) are packed and sealed inside the box (M). The box (M) is fitted and locked in the locking arrangement (2d) extruded from the surface (2”) of the exhalation valve assembly (2) in which the locking grooves (92f) in the box (M) locked with the locks (2d). Thus the box (M) is fixed in the exhalation valve surface (2”). Now then the exhalation valve flap and lever mechanism (N) is fitted rotatably to the holes (2b’) and the plate (95) inserted in the opening (92e) free to move inside/outside it.

The plane of the plate (95) is perpendicular to the axial line of the IR sensor (113) and IR LED (114) when came in their detection area. The bottom surface of the flap (93) rest on the circular opening (25”). There is various design of the IR proximity sensor (110) and hence not disclosed here. All components in the IR proximity sensor including the relay (115) but excluding IR sensor (113) and IR LED (114) is kept outside the IR sensor box (M) and housed inside the housing (3).

There is one flexible rubberized pipe (17) connected to near the top portion of the exhalation valve assembly surface (2”) and a small portion of it is inside the surface (2”). The pipe (17) is air tight when no straw is used for taking any fluid. When a straw is used for taking fluid, the straw is inserted in the rubberized pipe (17). The exhalation valve assembly surface (2”) is provided with the flexible pipe (17) to be used to insert straw for drinking water by the wearer if required. The flexible pipe (17) can also not be provided and in that case opening for it in the surface (2”) is closed.

The pins of the sockets (106a) and (106b) are connected to the battery (111) which supply power to the IR proximity sensor (110) and also to the coil of the relay (115) when the IR proximity sensor (110) is working. The cable (139) is a two core cable contains the cables (1171) and (117m) connected to the single pin socket/ connector (107a) and (107b) respectively fitted in the box (103) and their other ends connected to the two pins socket/connector (60) in the switch box (51). The pin of the single pin socket (107a) and (107b) are connected to the battery (121) in series with the switch (107c). An indication lamp, for giving indication about the status of close and open status of the relay (115), can be connected between the normally open contacts (115no) and the common terminal (115c) through a battery source and an ON/OFF switch.

The cable (137) is a two core cable contains the cable (117j) and (H7j’) connected to the two pin socket/connector (56) and to the fan (48a) terminals. One pin of the socket/ connector (60) inside the box (51) is connected to the one pin of the socket (56) and the other pin is connected to the one terminal of the ON/ OFF switch (53) whose other terminal is connected to one terminal (120’) of the toggle switch (54) fitted in the switch box (51) as shown in the Fig. -20. The terminal (119’)of the toggle switch (54) is connected to the cable (117k) whose other terminal is connected to the junction point (117g’h). Another out put terminal (118’) of the toggle switch (54) is connected to the one terminal (55”) of the fan/ speed regulator (55) fitted in the switch box (51).

The junction of the cables (117k) and (117g’) is connected to one end of the cable (117h) which is also connected to the terminal (117j) of the fan (48a) by its other end. The ON/OFF switches (52) and (53), the toggle switch (54), the speed regulator (55), the sockets (56), (57), (59) and (60) are fitted in the top cover (51a) fitted to the box (51) by screws (58) of the box (51) and their interconnections as explained above through various cables are kept inside the box (51).

When a wearer of the Aexpirator exhaled through the exhalation valve (25), the flap (93) gets lifted and the plate (95) moved inside the rectangular opening (92e) in the area between the IR sensor (113) and IR LED (114) of the IR proximity sensor (110) to obstruct/ stop infrared light sensing by the IR sensor (113) and the IR sensor (113) stop current passing through it. The flap (92) and the plate (95) rotate slightly forth and back about the pivot (94’) during exhalation and inhalation respectively. The main work of the exhalation valve (25) is to allow exhalation air out of the mask in one direction only and it acts like non return valve. The exhaled air enter in the IR sensor housing (3) area. During inhalation process the flap (93) sits on the edge (25”) and do not allow air to flow in the mouth area from the IR sensor housing (3) side and the plate (95) moved away from the IR proximity sensor (110) detection area and the IR sensor (113) starts allowing current to pass through it. In other words when the flap (93) moved away from the circular edge (25”) i.e. exhalation valve (25) is open, the IR sensor (113) stop conducting and when the flap moved and sit on the edge (25’) i.e. the exhalation valve (25) closed, the IR sensor (113) starts conducting. The interlocking of exhalation valve (25) with the fan (48a) is such that when the valve open the fan (48a) starts through closing of normal close contact of the relay (115). When the exhalation valve (25) is closed the IR proximity sensor (110) acts and energized the coil of the relay (115) through coil terminals (115a) and (115b) and the battery (111) and open its’ normally close contact (115nc) through which the fan (48a) circuit is connected and no power is fed to the fan (48a). When the exhalation valve (25) is closed the coil of the relay (115) de - energized, the normally closed contacts get closed and the fan circuits closed and the power through the battery (121) fed to the fan (48a) and it starts working. So there is interlocking between the exhalation valve (25) and the fan (48a).

The IR proximity sensor or any other sensor (110) capable of detecting opening and closing of exhalation valve (25) can be used. For explanation purpose and understanding of how the system in the present invention works IR proximity sensor (110) is taken. The scope of the invention is beyond this and any suitable sensor can be used instead of the IR proximity sensor and also any other non return exhalation valve e.g. disc type exhalation valve can also be used in stead of flap type exhalation valve without interlocking between the exhalation valve and the fan (48a). In that case the fan (48a) speed can be adjusted using the fan regulator (55) independently.

In place of flap type exhalation valve and IR proximity sensor (110) system disk type exhalation valve can also be provided in the surface (2”) and in this case the fan (48a) is manually and independently controlled.

The fan (48a) is kept inside the fan housing (48’) fitted on the top cover (29’) as shown in the Fig. -5. The battery (111) and (121) are kept in the control and battery box (103). The ON/OFF switch (52), the ON/OFF switch (53), the toggle switch (54), the fan regulator/ speed controller (55), the socket/ connector (56), the four pin socket/ connector (57), the socket/ connector (59) and the socket/ connector (60) are fixed in the switch board (51). The switch board (51) is fixed on the top cover (29’).

As zapper circuit or any other such circuits (Q) providing high voltage/ sufficient breakdown voltage to meet the requirement of the present invention is known to the world and hence not described in details.

Fig.- 10a broadly described the electric microbes killer unit (I) comprises electric microbes killer electrodes assembly (I’), electric microbes killer electrodes housing (4ia), base plate (4ia’) and cover/cap (4ib) with opening 4ic. The electrodes (I’) is having the anode plates (4id) and the cathode plates (4ie) stacking alternatively in spiral shape and fitted at their base in separate grooves, not shown in the Fig. -10a, in the base plate (4ia’), insulated from each other by insulating material coating (4if) on inner surface excluding base/ connecting leg (4id”) and 4ie” and sharp edges (4id’) and (4ie’) respectively. The anode plates (4id) is curved shape having two opposite sharp edges (4id’) and one connecting leg (4id”) on right side at the bottom which is inserted in the groove in the base plate (4ia’ ). Inner side of the curved surface of the anode plate (4id) is provided with electrical insulating warmish or paint or insulating layer or electrically insulating material coating (4if) except the leg (4id”) area and two opposite sharp edges (4id’).

There are a large number of anode plates (4id) and cathode plates (4ie) with inner side coated with the insulating material (4if) are stacked/ placed one behind other following spiral path as shown in the Fig. -10a. Distance between two plates (4id) and (4ie) is kept as low as to achieve the goal of electrically breaking the air gap between their sharp edges (4id’) and (4ie’) when the respiratory droplets or microbes laden air passed/ enter between these sharp edges (4id’ ) and (4ie’) area killing microbes due to electrical breakdown and finally electrically electrocuting microbes. The anode plates (4id) are parallelly and electrically connected to each other and to the one end of the capacitor (130) of the zapper circuit (Q) as shown in the Fig. -21. The cathode plates (4ie) are parallelly and electrically connected to each other and to other end of the capacitor (130) of the zapper circuit (Q) as shown in the Fig. -21. There is one ON/OFF switch (156) provided for switching ON or OFF power supply to the electric microbes killer electrodes assembly (F) of the electric microbes killer electrodes unit (I) or (132) connected to the capacitor (130) through cables (131’), (131), (123h), (123g), (123g’) in series with the switch (156).

The anode plates (4id) and the cathode plates (4ie) are connected to the inner pins of the socket (4ig) and power supply to them is obtained from the zapper circuit (Q) through cables (131) and (131’) connected to the socket (4ig). When the switch (156) is ON and the capacitor (130) is sufficiently charged and then when the respiratory droplets or microbes laden air enter the area between the sharp edges (4id’) and (4ie’), electrical breakdown happens and arc is generated that vaporized the water in the respiratory droplets or short circuits microbes laden air and kill microbes including SARs-CoV-2 viruses in the respiratory droplets. When a person exhaled the exhaled air or respiratory air also containing respiratory droplets enter the electric microbes killer electrodes housing (4ia) through the opening (4ic) and follow the spiral path (4ik) between the stacked electrodes (4id) and (4ie) and exit the housing (4ia) through the opening (4ib’) microbes and viruses gets electrocuted. The electrodes unit (I) or (J) having the electrodes (I’) or (J’) respectively is kept inside the electric microbes killer body or housing (4) mounted on the IR proximity sensor housing (3). Another unit of the electrodes unit (I) or (J) with the electrodes assembly (I’) or (J’) respectively is kept in the microbes filter (7b) and their anode electrodes and cathode electrodes are connected parallel to the capacitor (130) of their zapper circuit (Q). Another unit of the electrodes unit (I) or (J) with the electrodes assembly (I’) or (J’) respectively is kept in the housing (37’) and their anode electrodes and cathode electrodes are connected parallel to the capacitor (130) of their zapper circuit (Q).

The stack is kept in place using the nut - bolts (5j c’) passed through the holes (5jc) in the anode plates (5ja) and cathode plates (5jb) and the nut - bolts (5jc”’) passed through the holes (5j c”) in the anode plates (5ja) and cathode plates (5jb). There are curved surface in opposite longer sides of the anode plates (5ja) and the cathode plates (5jb). There is the rectangular opening (5jf) in the inner central area of the anode plates (5ja) and the rectangular opening (5jf ) in the inner central area of the cathode plates (5jb). The legs (5ja’”) are connected electrically near the hole (5ja””) to each other and then to the one end of the capacitor (130) of the zapper circuit (Q) as shown in the Fig-21. The legs (5jb’”) are connected electrically near the hole (5jb””) to each other and then to the other end of the capacitor (130) of the zapper circuit (Q) as shown in the Fig-21. The electrodes (J’) is connected to the capacitor (130) through cables (131’), (131), (123h), (123g) in series with the switch (156) as shown in the Fig. -21. The electrodes assembly (J’) is kept in a housing not shown in the figures and the housing is kept in the electrics microbes killer unit housing (4). There is provision in the housing (4) for keeping either the electrodes unit (I) or the electrodes unit (J). Both electrodes assembly (I’) and (J’) can not be placed at one place but in either (I’) or (J’) or (I’) and (J’) at different places can be used. The exhalation air or respiratory air flows from top to the bottom touching outer sharp edges (5ja’) and (5jb’) and flows through central area (5jf) touching inner sharp edges (5ja”) and (5jb”). When respiratory droplets or microbes laden air touches edges (5ja’) and (5jb ’) or (5ja”) and (5jb”) of both plates (5ja) and (5jb), the voltage applied to anode and cathode breaks down the electric field between edges of these electrodes (5ja) and (5jb) and the respiratory droplets vaporized or microbes laden air short circuited and the microbes or the SARs-CoV-2 virus gets burnt during the process killing SARS-CoV-2 viruses and microbes.

The chemical/ sanitiser microbes killing and crippling system (Da) broadly comprises the body (28) and the top cover (29’) of the housing (28), the chemical/ sanitiser storage tank with float operated valve or float controlled water discharge system (H), the air diffuser system having air tubes or air stone diffuser or plate diffuser etc. (K), the float ball operated valve system (P) attached to the tank (H), the mesh/ jail (99), the mesh/jail (97), the microbes and virus killer chemical/ sanitizer (29a), the fan (48a) and its power supply through the battery (111) or any other independent power supply, the switch box (51’), switches (52), (53), the fan regulator and the toggle switch (54) and their connections through cables. The position of the toggle switch decides whether the fan (48a) operates independently or interlocked with the IR proximity sensor (110). The coupler (47) of the air diffuser system (K) is inserted in a hole in the top cover (29’) and tighten with the nut (47b) after inserting the washer (47a) from the bottom. The exhalation air diffuser body (47c) or (47d) or (47e) is passed through the opening (98) in the mesh/ jail (97). The mesh (97) is placed and locked inside the housing (28) above the top portions (32) of the groves (32’), the top portions (33) of the groves (33)’ and the top portion (34’) of the grooves 34” on the left side face (not visible) of the body (29). The mesh (99) having four holes (99’) and the hanging threads (100) are attached to the top cover (29’) and placed above the mesh (97) towards the pipe connector. The float operated valve system (P) is attached to the bottom of the tank (H) by inserting the union coupling (5h) in a hole (lh”) in the bottom of the tank (H) and tighten with the union nut (4h) as shown in the Fig. 9 and Fig. 15. The tank (H) is kept at top edges (34) in front wall and the top edge (34) in rear wall and top portion (34’) of the side groove (34”). Top edges of the tank/ container (lh) is covered with the bottom surface of the cover (29’) when the box (28) is closed. A separate cover with a hole matching with the opening of the tube (35) for topping up chemical/ sanitiser in the container (lh) can also be used. The tube (35) is covered with the cap (36). The body (29) and the container (lh) are sufficiently filled with Chemical/Sanitiser (29a). The air tubes (47c’) or the diffusers (47f) or the diffuser (47h) is submerged in the chemical (29a). When the fan (48a) working, the air passed through the air tubes (47c’) or the diffusers (47f) or the diffuser (47h) and then to the chemical (29a) and then came out of the housing (28) through the pipe connector (61). During this process the chemical gets evaporated resulting into consumption of the chemical (29a). To compensate for the loss of the chemical (29a) the chemical/ sanitiser storage tank with float operated valve or float controlled water discharge system (H) supply it through. The chemical can be top up through tube (35).

Air diffuser systems (K) as described in the Fig.- 11 comprises the coupler (47) having a male threaded end (47”‘), the washer (47a), inserted in its’ and then screwed in it the nut (47b) and then screwed in it is the female socket end (47c”) of the diffuser body (47c). The body (47c) is having female socket end (47c”) is connected to the male threaded end (47”‘) and the air tubes or pipes (47c’) either fitted in the bottom surface of the diffuser body (47c) or extruded from it.

There are three types of diffuser body (47c), (47e) and (47g) disclosed. There is one safety valve (47d) fitted in the outer body surface (47c”‘) or (47e”‘) or (47g”‘) of the body (47c) or (47e) or (47g) respectively. The body (47e) is having female socket end 47e” for connection to the coupler (47) and the air tubes or pipes (47e’) either fitted in the bottom surface of the diffuser body (47e) or extruded from it and the bottom end of the tubes (47e’) is coupled to the bush (47f ) of the air stones (47f). The body (47g) is having female socket end 47g” for connection to the coupler (47) and the air tubes or pipes (47g’) either fitted in the bottom surface of the diffuser body (47g) or extruded from it and the bottom end of the tubes (47g’) is coupled to the bush (47h’) of the plate diffuser (47h). In Fig-5, the coupler (47) is inserted in a port in the top cover (29’) of the microbes killer and crippling unit (D). Only male threaded end (47”‘) is inserted in the port and the top body sit on the surface of the cover (29’). The washer (47) is inserted in the male threaded end (47”‘) and the coupler (47) is tighten in the cover body (29’) by tightening the nut (47a) in the male threaded end (47”‘). Now female threaded socket (47c”) of the diffuser body (47c) is screwed and tighten in the male threaded end (47”‘). Instead of the body (47c), other diffuser body (47e) connected with the air stones (47f) or the diffuser body (47g) connected with the plate diffuser (47h) can be used. The fan housing (48’), inside which the fan (48a) is housed, is sandwiched between the flange (47’), as shown in the Fig.11, and the flange (49a) of the coupler (49) and hold in place by the four nut - bolts (50). There is an opening in the fan housing (48’) through which cables (117j) and (H7j’) taken out and the opening is air tight sealed. The body (29) is filled with chemical or sanitizer upto a suitable level dipping the tubes (47c’) or (47e’) or (47g’). During working of the present invention Aexpirator the chemical or sanitizer gets evaporated. In order to maintain a certain level of it inside the box (28) there is one storage tank (H) with automatic flushing system is fitted inside the box (28) to automatically meet the short fall.

The storage tank (H) is described in the Fig. -9(a) and 9(b). The float ball operated valve system (P) is described in Fig. -9(a), Fig. -9(b) and Fig. -15. The storage tank (H) comprises the container (Ih) having a level indicator glass (lh’) on its wall, a port (lh”) at the bottom surface for connection of the float valve system (P), an inside grooves/ protrudes (lOh) and the supporting plates (9h).

The float system (P) parts are described in the Fig. -15 and Fig. -9. The male threaded end (1 lh’) of the float ball (2h) operated valve body (1 lh) is inserted first in the washer (12h) and then in the port (lh”) in the bottom surface of the container (lh). The washer (12h) sits on the collar (1 Ihb). There is one hole (1 lh”) in the header (1 lha) of the body (1 lh) through which the sanitizer (29a) kept in the tank (H) passed to the body (29) when the plunger (6h) is in down position. After that the plunger (6h) with grooves (6ha) having washer (6h’) fixed at its header (6hb) top end inserted with top end inside the valve body (1 lh). Top of the isolation and seating gasket (12h’) sits on the bottom edge of the male threaded end (Uh’). The hollow top step (5ha) of the stepped insert (5h) sits on the bottom side of the seating gasket (12h’). The rod (6h’”) of the plunger (6h) passed through the hollow bottom step (5hc) and free to move. The lower face/ surface (6hc) of the head of the plunger (6hb) sits on the bottom inside face of the hollow middle step (5hb). Then the union nut (4h) is tighten in the male threaded end (1 lh’) from bottom side of the container (Ih). The union nut (4h) air tight the stepped insert (5h) with the valve body (1 lh) with the sealing gasket (12h’) in between them. The plunger (6h) is free to move inside the body (1 lh) and the stepped insert (5h) but not allow to move away from the insert (5h). The female threaded end connector (2h’) of the float ball (2h) is screwed in the male threaded end (3h’) of the connecting rod (3h). The hole (3h”‘) near far end in the rod (3h) is matched with the hole in the support plates (9h) and the rod (3h) is pivoted at this point by the rivet/ connecting pin (8h) and free to move up and down about this pivot. The hole (3h”) is at appropriate place in the rod (3h) and connected to the holes (6h”) in the bottom end of the plunger (6h) by the rivet/ connecting pin (7h). The rod (3h) is pivoted at (3h”‘) and connected to the plunger at (6h”). When the float (2) moves up or down the plunger (6h) moves up or down respectively. The container (lh) is filled with the chemical/ senitiser (29a). The chemical/ senitiser (29a) is filled through a tube opening (35) in the top cover (29’). There is a valve sheet (12h”) inside the valve body (1 lh) on which the washer (6h’) sits when the rod (3h) lifted up and rotate about the pivot (8h) when the float ball (2h) is lifted up to a desired level and there is no flow of chemicals/ sanitizer from the storage tank (H) through the hole (Hh”) and hollow space in the bottom step (5hc) to the body (29). When the float ball (2h) is lowered the rod (3h) moved down resulting into the plunger (6h) moved down and the washer (6h’) moved away from the valve sheet (12h”) and then the chemicals or sanitizer (29a) starts flowing from the container (lh) to the body (29) through the hole (1 lh”) and the hollow space in the bottom step (5hc) there by maintaining a certain level of the chemical in the body (29). The chemicals/ sanitizer is filled or topped up through the tube (35). There is level indicator glass (56a) which shows sanitizer (29a) level in the storage tank (H). There is the level indicator (lh’) in the tank (lh).

The safety valve (47d) is provided in the diffuser body (47d) to blow when the pipes (47c’) or (47e’) or (47g’) or the stone diffuser (47f) or the plate diffuser (47h) is choked. When exhalation air or respiratory air passes through the pipes (47c’) or the air stone (47f) or the plate diffuser (47h) and enter in the chemical or sanitizer (29a) kept in the box (28) the air bubble emerged and microbes contained in the air bubble gets mixed with the chemical or sanitizer (29a) resulting into vapourisation of the chemical/ sanitiser (29a) and reduction in the level of the chemical (29a) in the body (29). This depletion of the chemical (29a) in the housing (29) is compensated by the chemical (29a) supplied from the tank (lh). During this mixing the microbes including SARS-CoV-2 viruses or any other viruses gets killed or crippled or decomposed or their power or strength gets reduced so that they can no longer harm human. The purified exhaled air came out of the box (28) through the pipe connector (61). There is some possibility that some microbes in the exhalation air out side the box (28) may be available. To further strengthen the system the exhaled air after the box (28) passed through the UV-C lamp system (E) explained below.

As described in the Fig.16(a), three layers of the mesh/ jali (97) separated by side plates (97’) is having a cylindrical opening (98) through which the tubes (47c’) or (47e’) or (47g’) passes and their lower ends partially submerged in the liquid chemical or alcohol sanitizer (29a) in the box (28) as shown in the Fig. -16a, Fig. -11 and Fig. -5. The stacked mesh (97) is kept inside the box (28) and supported on the grooves (32) and (33) is above the top surface of the liquid chemical or alcohol based sanitizer or an other liquid chemical (29a), capable of killing microbes including SARs-CoV2 viruses, kept in the box (28). The mesh (97) do not touches the chemical or sanitizer (29a).

As described in the Fig. -16(b), there are four holes (99’) in the mesh/ jali (99) through which it is fixed inside the cover (29’) of the box (28) and above the mesh / jali (97) in such a position that the exhaled air passed through the hanging threads (100) before discharging to the pipe connector (61).

The fan system (F) comprises the box (72) having the main body (73) air tight fitted with the top cover (73’) and hinged by hinges (74), a port in the top cover (73’) to which the fan housing (79) is fitted having the exhaust fan (79a) housed inside it, a port in the one side wall of the body (73) to which the inlet pipe connector 77 is fitted, a port in the cover (73’) to which the air pipe connector (91) is fitted to which one end of the air pipe (90) is connected, a port in the bottom surface of the body (73) to which the drain pipe (86) fitted and the drain pipe (86) is air tight fitted with the cap (86’), two hooks or rings (75) is connected at back end and fixed in the waistbelt (133), the switch board (82) is fixed on the top cover (73’) is connected to the fan (79a) by the two core cable (81) and to the battery 127” in the box (103) through the cable (143) is connected to the socket (109a) and (109b) fitted in the box (103) and the socket (83) is fitted in the switch box (82) having the ON/OFF switch (85) and the fan/ speed regulator (84) is fitted in the top cover (82’) fixed to the body of the box (82) by four screw (82”) and the air pressure regulator (87) is fitted on the top cover (73’) using the nut-bolt- washers (88) and (89) and is connected to other end of the air pipe (90). Opposite end of the pressure regulator (87) is open to the atmosphere. A number of filters (72a) are suitably placed and provided inside the box (72) in the exhalation air path. Inside two pins of the socket (83) is connected in series with the fan (79a), the ON/OFF switch (85) and the fan regulator (84). The inlet pipe connector (77) is inserted in the washer (76) and then inserted in a port in the side wall and tighten by a nut from inside of the box (72). The fan regulator (84) and the air pressure regulator (87) set vacuum or negative air pressure in the area above the chemical or sanitizer liquid (29a) kept in the box (28) and helps sucking exhalation air or respiratory air and provide ease of working of the invention Aexpirator and comfort to the wearer. The fan system (F) sucked the exhaled air through the UV-C lamp system (E) and expelled in the air through the mesh or jali cover (80). Filters (72a) provided in the box (72) absorb chemical or sanitizer in the exhalation air before delivering the exhalation air to the atmosphere/ ambient.

If a large number of the invention Aexpirator is to be used in one hall/ room then it is better not to expelled the exhaled air to atmosphere individually but we should have a piping system connected to the pipe connector (101c) of the connector (101) air tight fitted to top of the fan housing (79) of each wearer of the invention Aexpirator and other end of the piping system exposed to the atmosphere/ ambient after another filtration system. This way we can kept a large number of virus infected persons, wearing the invention Aexpirator, in a hall and kill and weaken a large number of viruses in expelled exhalation air to the atmosphere which will not be able to infect other person.

Fig.-l, Fig. -2, Fig. -3, Fig. -4 and Fig. -12 describes the non return valve/ check valve or inhalation valve (L) comprises the main body (6), inserted and fixed in the two ports (61) in the exhalation valve body (2’), having the rim or the female socket end (6’), mail threaded end (6”) at the central location and the receiver socket end (6”’) in the opposite side of the main body (6) in which the disc (6a) is kept and free to move inside the receiver (6”’) and then the pipe (6b) is inserted in the receiver (6”’) and fitted.

The box (103) also contains four zapper circuits (Q) each connected to the electric microbes killer electrodes (F) or (J’) fitted in the two microbes filters (7b), in the housing (4) and in the box (37’). The battery box (103) supply power to all the electrical devices used in the First and Second embodiments of the present invention.

Fig.- 21 described the zapper circuit block diagram (Q). There are different types of the zapper circuit (Q) available in the market of which any type can be used to meet the requirement of high or desired output voltage. Any other circuits can also be used in place of Zapper circuit (Q) which is capable of producing high or desired out voltage with battery charging facility and battery available. Since Zapper circuit (Q) alone is not claimed in the present invention the Aexpirator and hence it is not disclosed and discussed in details.

In the block diagram the three pin slide switch (104c) or (105c) or (144c) or (145c) or (155) is in a position connecting the battery (127) to the battery charger (125). The ON/OFF switch (124) is connected to the battery charge (125) by the cable (123c) and its’ other end is connected to the cable (123b). The power supply (123) is fed to the battery charger (125) for charging the battery. Negative terminal of the battery (127) is connected to junction point of the cable (123k) and (123j) through the cable (126). The battery charger (125) and the oscillator circuit and voltage step up system (128) are also connected to the cable (123k) and ( 123j ) respectively. The positive terminal of the battery (127) is connected to the pin (c’) of the three pin slide switch (104c) or (105c) or (144c) or (145c) or (155). The output of the battery charger (125) is connected to the pin (a’) of the switch (125) by the cable (123d). The pin (b’) of the switch (104c) or (105c) or (144c) or (145c) or (155) is connected to the oscillator circuit (128) through the cable (123 e). The circuit (128) is connected to the voltage multiplier circuit (129) through cables ( 123f) and ( 123i). The output of the voltage multiplier circuit (129) is connected to the capacitor (130) through the cables (123g) and (123h). The cable (123g) is connected to one side of the ON/ OFF switch (38) or (39) or (156) or (104e) or ( 105e) or (144e) or ( 145e) and its’ other end is connected to the block (132) or the electric microbes killer electrodes assembly (I’) or (J’) through the cable (131’) or (140’) or (141’). The other end of the block (132) is connected to the cable (123h) through the cable (131) or (140”) or (141”). When the ON/ OFF switch (124) is in ON position and the pin a’ connected to the pin (c’) in the slide switch (104c) or (105c) or (144c) or (145c) or (155) the electric power (123) is fed to the battery (127) through the battery charger (125) and the battery (127) starts charging. During this condition no power is fed to the capacitor (130). If the capacitor (130) was charged earlier and not discharged than it may have charge voltage and electrical power can be fed to the load (132) for a very short time.

After charging the battery (127) the pins (c’) and (b’) of the slide switch (104c) or (105c) or (144c) or (145c) or (155) is connected to the oscillation circuit (128). When the switch (38) or (39) or (156) or (104e) or (105e) or (144e) or (145e) is ON the battery (127) power after step up and voltage multiplication fed to the capacitor (130). When the anode (4id) and the cathode (4ie) electrodes or the anode (5ja) and cathode (5jb) electrodes gets shorted due to respiratory droplets or any other reason the electrical breakdown happened and the capacitor (130) power discharged and the water in the respiratory droplets evaporated and the microbes in the respiratory droplets get burnt. So this is the mechanism of electrocuting and killing microbes in the respiratory droplets or air in the present invention the Aexpirator.

The electric microbes killer unit (I) or (J) comprises the electric microbes killer electrodes assembly (I’) or (J’) connected to the zapper circuit (Q).

The non return valve (L) can be disc type or check type inhalation valve fitted to the filter/cartridge (7).

The aexpirator mask is worn by the wearer in the face and tightens with the head strap (12) and the neck strap (11). The sponges (21) and (22) cover the nose, cheek and chin area and sealed the area infront of the mouth and nose and create a cavity. This arrangement do not allow air to enter in the cavity through the sponges (21) and (22). When wearer inhaled, the air enter the cavity through the cartridge (7) and the inhalation valve (L) and not enter through the exhalation valve (25). When the wearer exhaled, the exhalation air or the respiratory air passes through the exhalation valve (25), the electric microbes killer electrodes (T) or (J’) in the housing (4), the hose (G), the electric microbes killer electrodes (T) or (J’) in the housing (37’), the fan (48a) in the housing (48), Chemical/ Sanitiser microbes killer and crippling system (Da) including the diffuser (K), the liquid chemical or sanitizer (29a) kept in the body (29), the stacked filters (97), the hanging threads or ropes (100), the pipe connector (61), the connection pipe (102), the pipe connector (70), the pipe connecting the pipe connectors (70) and (68) of the UV-C lamp system (E), the connection pipe (102), the pipe connector (77), the filters inside and the fan housing (79) of the exhaust fan/ fan/ air pump/ blower/ negative pressure generator unit with air filters system (F) and finally to the atmosphere. During this travel microbes including SARS-CoV-2 virus or any other influenza virus available in the exhalation air or respiratory air either become dead or lost their power and become ineffective in infecting any person.

During inhalation process the inhaled air enters the cartridge (7) through the filter mesh/ jail (8) and passes through the microbes filter (7b), mechanical filter (7a) and then enter the cavity through the inhalation valve (L). The microbes filter (7) burn or cripple the microbes in the inhaled air as shown in the Fig.1 and Fig.2.

When the wearer of the present invention Aexpirator exhaled, the disc (6a) touches seating in the receiver socket (6’”) of the inhalation valve (L) not allowing exhaled air to pass through the cartridges (7) and the flap (93) of the exhalation valve (25) is lifted and moved away from the circular edge (25”) allowing the exhaled air to enter in the hose pipe (G) via the microbes killer electrodes (I’) or (J’) in the housing (4). During inhalation the IR proximity sensor (110) is ON and the flap (93) touches the circular edge (25”) and the plate (95) is not between the IR sensor (113) and IR LED (114) and away from the hole (92e). In this situation the relay (115) coil is energized and the NC contact is open and the fan (48a) is not started and inhalation air do not pass through the exhalation valve (25). During exhalation when the flap (93) moved away from the circular edge (25”), the plate (95) enters the hole (92e) and block the IR sensor (113) to sense IR emission by the IR LED (114) resulting into de-energisation of the coil of the relay (115) and closing of its’ NC contact. This will starts the fan (48a) and the fan (48a) create enough vacuum in the hose pipe (G) and the housing (4) sucking respiratory or exhaled air. In stead of IR proximity sensor (110) and exhalation valve (25) only disc type exhalation valve can be used and there will not be requirement of the relay (115) and the fan (48a) shall be adjusted independently to continuously work and produce enough vacuum in the hose pipe (G) and the housing (4) to suck the respiratory or exhaled air. Also the fan (48a) pushed the respiratory or exhaled air in the chemical/ sanitizer (29a) kept in the box (28) through the chemical/ sanitiser microbes killer and crippling system (Da). The respiratory bubble mixer of the chemical (29a) and the microbes laden respiratory air passed through the hanging ropes (100). The fan or exhaust fan or air pump or negative air pressure generator or blower (79a) sucked the respiratory bubble mixer through the UV-C system (E) and the filters inside the exhaust fan/ fan/ air pump/ blower/ negative pressure generator unit with air filters system (F). The output air passes through the mesh or jail cover (80). There is one connector (101) for the housing (79), as shown in the Fig.17, which can be connected to another air purifying system to further clean the air.

The connector (101) comprises of the main hollow body (102b) connected from its circumference is the hollow pipe connector (101c). The body (101b) is connected to the female socket end (101a). There is a barbed push lock fitting (101 d) in the connector pipe (101c).

There are mainly three stages of killing microbes or SARS-CoV2 virus or any influenza virus in the respiratory droplets (i). Electrocuting them in the anode and cathode plates of the electrodes assembly (F) or (J’), (ii). Killing and also reducing their power of infection by mixing them with the chemical/ sanitiser (29a), capable of killing them, in the exhalation air cleaning system (D) and (iii). Passing them through UV-C system (E). The three stage killing system will kill almost all microbes or viruses available in the respiratory droplets when passed through the present invention the Aexpirator.

The exhalation air cleaning system (D), the UV-C lamp system (E), the fan unit with filtration system (F) and the battery box (103) are hooked/ fixed in the belt (133) and worn by the wearer as shown in the Fig. 22.

The aexpirator mask (A) is worn by a wearer in face and tightens with the head strap (12) and the neck strap (11).
