The shell 1 is located next to the liquid injection hole 12 and is internally provided with a groove 120 to accommodate the cover 42. The hole plug 41 is used to block the injection hole 12 after the injection to prevent the liquid from leaking out. The hole plug 41 is provided with a cover 42, which is convenient for pulling out the hole plug 41 and opening the liquid injection hole 12 by lifting the cover 42 by hand when adding liquid.

[00041] As shown in Figures 4 and 5, the pressing part 3 includes a soft rubber sleeve 31, a button 32 and a button cavity 30 for accommodating the button 32. The soft rubber sleeve 31 is made of soft colloid. The button cavity 30 is arranged in the shell 1, a partition plate 13 is arranged between the button cavity 30 and the liquid storage cavity 10, the button 32 is arranged in the button cavity 30, the soft rubber sleeve 31 is fixed at the front end of the shell 1, and the inner side of the soft rubber sleeve 31 is connected with the button 32. The soft rubber sleeve 31 has certain elasticity. When the soft rubber sleeve 31 is pressed by hand, the button 32 is pressed at the same time. When the soft rubber sleeve 31 is relaxed, the soft rubber sleeve 31 returns to reset, and the button 32 is driven to return to reset.

[00042] As shown in Figures 4 through 8, a suction pipe 5 is arranged in the liquid storage cavity 10, and the tail section 51 of the suction pipe 5 extends into the button cavity 30 and is fixed on the partition plate 13. A check valve (not shown in the figure) is arranged inside the front section 52 of the suction pipe 5 to prevent the solution in the suction pipe from flowing backward when the button 32 is pressed. A sealing ring 53 is arranged at the joint between the tail section 51 of the suction pipe and the baffle plate 13, and the sealing ring 53 is used to prevent the liquid in the liquid storage cavity 10 from leaking through the connection.

[00043] The inner part of the button 32 is provided with a piston chamber 320 which can accommodate the tail section 51 of the suction pipe along the pressing direction, and the piston cavity 320 is set on the tail section 51 of the suction pipe, which can make axial reciprocating motion on the tail section 51 of the suction pipe. The bottom of the piston chamber 320 is perpendicular to the piston chamber 320 and is provided with a discharge pipe 321 connected with it. The inner side of the nozzle 11 is provided with a nozzle 6. The nozzle 61 of the nozzle 6 is directly opposite to the nozzle 11, and a nozzle 7 is connected between the discharge pipe 321 and the nozzle 6.

[00044] The principle of the spray is that when the press is pressed by hand, 31 , the button 32 is pressed at the same time, the button moves towards the front 51 of the straw 5, the inner cavity space formed by the piston chamber 320 and the tail section 51 of the straw is compressed, and the volume decreases. The tail section 51 is a part of the mechanism of sprayer and it goes inside of the part 5 and compress internal volume of liquid that caused the liquid go through the tail section 51 to outside. When the button 32 is pressed the liquid is already inside of the part 5 wherein the compression forces the liquid to go out. The back section of the straw 5 has a check valve to prevent the solution from being reversed, so that the liquid in the piston chamber 320 is extmded and discharged to the discharge pipe 321. The liquid is extruded into the nozzle 6 through the nozzle 7, and further, the liquid is ejected through the nozzle 61 in the nozzle 6 and ejected through the nozzle 11, and the liquid is atomized due to pressure extrusion.

[00045] When the thumb is pressed when the rubber sleeve is relaxed, the rubber sleeve 31 is reset back and forth, and the button 32 is also reset. The volume of the inner cavity space formed by the piston cavity 320 and the tail section 51 of the straw is increased, forming a certain vacuum, causing suction in the straw 5 to suck and suck the liquid. When the housing is filled first time its needs to be pumped several times to start working and only one push is required moving forward to spray the liquid out. in the liquid storage chamber 10 and accumulate in the 320 of the plug chamber.

[00046] Alluding to the above, the portable disinfector sprayer of this embodiment is designed to be hand-held and small in size and can be clamped on the waist belt by clamping 2 when going out. When the utility model is not used, the palm is close to the sprayer and the thumb press the pressing part 3, so that the disinfectant solution in the liquid storage chamber 10 can be sprayed on the palm of the palm and can be sterilized at any time. Therefore, the portable disinfector sprayer is convenient to carry and can be conveniently used at any time.

[00047] As shown in Figures 5 through 8, a clip 8 is arranged at the joint of the discharge pipe 321 and the nozzle 7 and the joint of the nozzle 6 and the spray nozzle 7, and the clamp 8 is used to fix the nozzle 7. A clamping groove 3210 is arranged on the discharge pipe 3210, which can accommodate the blocking clip 8, and the clamp 8 can clamp and fix the nozzle 7 in the clamping groove 3210, so that the solution in the discharge pipe 321 is extruded and the nozzle 7 will not fall off due to the force. Similarly, the connection of nozzle 6 and nozzle 7 has the same clamping groove and clamping structure, so that the nozzle 7 will not fall off. [00048] As shown in Figures 9 and 10, the front section 52 of the suction pipe is connected with an elbow 9, and the suction end of the elbow 9 is arranged at the bottom of the liquid storage chamber 10. In this way, when the liquid in the liquid storage chamber 10 is less, the liquid will accumulate at the bottom of the liquid storage cavity 10, so that the suction end of the elbow 9 can still inhale liquid and deliver it to the suction pipe 5. The inner wall of the liquid storage chamber 10 is located at the suction end of the elbow 9, and is provided with a fixing plate 16, which is used to fix the suction end of the elbow 9, so as to ensure that the suction end of the elbow 9 is fixed at the bottom of the liquid storage chamber 10, so that the liquid in the liquid storage cavity 10 can continue to be inhaled after the liquid in the liquid storage cavity 10 is reduced.

[00049] As shown in Figures 10 and 11, the connection of the shell 1 and the soft rubber sleeve 31 is provided with a number of convex pillars 17, the two sides of the soft rubber sleeve 31 are provided with a number of fixed through holes 310, and the convex pillars 17 are sheathed in the fixed through holes 310, so that the soft rubber sleeve 31 is fixedly connected to the shell 1. The two sides of the button 32 are provided with a long strip-shaped limit through hole 322. One of the boss 17 is threaded in the limit through-hole 322. The button 32 can only move back and forth in the limit through hole 322 due to the limitation of the boss 17. In this way, the movement direction of the button 32 cannot be dislocated, resulting in uneven stress and deformation of the tail section 51 of the suction tube.

[00050] As shown in Figure 10, the inner wall of the button chamber 30 is provided with a fixed seat 18 at the nozzle 11, and the spray head 6 is fixed in the fixed seat 18, so that the nozzle 6 cannot fall off or deviate when the spray force is applied, so that the nozzle 61 cannot be accurately aligned with the nozzle 11. [00051] The above description is only a better embodiment of the invention, and the above specific embodiment is not a limitation of the invention. Within the scope of the technical idea of the invention, various deformations and modifications can occur. All the embellishments, modifications or equivalent substitutions made by ordinary technicians in the art according to the above description belong to the scope of protection of the invention.

[00052] While the invention has been described with reference to an exemplary embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof.
