DETAILED DESCRIPTION OF THE INVENTION

In the following description, the surface of the mattress body applied for supporting the user is defined as the upper surface of the present invention in accordance with the common understanding of people having ordinary skills in the field. Referring to Fig.1 to Fig. 4, the structure of an air conditioning air-permeable mattress is illustrated, comprising a mattress body 10 and a ventilation module 50 (as shown by Fig. 6.). The ventilation module 50 is located outside the mattress body 10. The ventilation module 50 comprises a pipeline 51 connected with a cavity 15 inside the mattress body 10. The mattress body 10 comprises a top face 11 and a bottom face 13 formed in a plate shape, and a circularly-shaped side wall 12 between the top face 11 and the bottom face 13, wherein the top face 11, the side wall 12, and the bottom face form an internal cavity 15. The top face 11 comprises a plurality of air outputting bores 111 distributed thereon and connected with the cavity 15. The outer lateral side 121 of the side wall 12 comprises an air inlet 122, and an inner lateral side 123 of the side wall 12 comprises an air outlet 124 connected with the cavity 15.

In this embodiment, the air inlet 122 and the air outlet 124 of the mattress body 10 are respectively an inner opening and an outer opening of a through hole passing through the side wall 12. The pipeline 51 of the ventilation module 50 passes through the air inlet 122 and the air outlet 124, so that an air inputting opening 52 of the pipeline 51 is connected into the cavity 15. Notably, referring to the embodiment of Fig. 8, the air inlet 132 and the air outlet 134 are allowed to be opened on two lateral sides of the bottom face 13, wherein the air inlet 132 and the air outlet 134 form a through hole passing through the bottom face 13, whereby the pipeline 51 of the ventilation module 50 passes therethrough for providing the air supply. Further referring to Fig. 1 to Fig. 4, the cavity 15 inside the mattress body 10 is connected to the outside only through the air outlet 124 and the air outputting bore 111, so that the air supply provided by the ventilation module 50 flows almost only toward the air outlet 124. The cavity 15 inside the mattress body 10 is designed to evenly distribute the air supply to the overall cavity 15, and then the air supply passes through the air outputting bore 111 to be distributed to the upper face of the mattress body 10, thereby maintaining the ventilation, lowering temperature, and providing a temperature for comfortable sleeping. In addition, the ventilation module 50 is disposed outside the mattress body 10, so as to prevent the running noise of machine from affecting sleeping quality of the user, and also facilitate the convenience of subsequent maintenance and filter screen replacement operation. Notably, a photocatalyst module or filter screen (such as HEPA filter screen) may be disposed between the pipeline 51 of the ventilation module 50 to purify or filter the air supply, maintain the quality of the air discharged from the air outputting bores 111, and disinfect or sterilize the inside of the mattress body 10. Also, a temperature adjusting module may be disposed in the pipeline 51 of the ventilation module 50 for adjusting the temperature of the air delivered into the cavity 15 by the ventilation module 50. Therein, the ventilation module 50 and the temperature adjusting module are electrically connected with a control module. Therefore, an air supply condition is able to be set for adjusting the internal temperature inside the mattress body 10, whereby the user lying on the mattress body 10 feels a proper temperature, so as to improve the living quality and increase the sleeping quality. Also, usage of the present invention is healthier and more environmentally friendly.

Also, the top face 11 of the mattress body 10 is covered with a surface fabric layer 60 for adjusting the air pressure of the top face 11. The surface fabric layer 60 is allowed to be a knitted fabric, woven fabric, or air-permeable film. When the air pressure of the top face 11 reaches a predetermined value, the air in the cavity 15 permeates through the surface fabric layer 60 to the outer side of the mattress. Regarding the air pressure adjustment method of the surface fabric layer 60, for example, the pore density is configured to be able to adjust the flow rate of the air after passing through the air outputting bores 111. For another example, the fabric density of a specific area of the surface fabric layer 60 of the top face 11 is configured to be able to adjust the flow rate of the air passing through the air outputting bore 111. For still another example, the surface fabric layer 60 covering the top face 11 is partially air-permeable and partially air-impermeable.

In detail, all six surfaces of the outer lateral side of the mattress body 10 are covered by the surface fabric layer 60. The fabric density of the fabric covering the top face 11 is lower than the fabric density of the fabric covering other surfaces (side wall 12 and bottom face 13). Alternatively, the fabric covering the side wall 12 and the bottom face 13 is formed of air- impermeable material, such as plastic fabric or an emulsion attached fabric, such that the air flow of the cavity 15 of the mattress body 10 is only allowed to flow toward the top face 11, whereby the air flow is concentrated on the user, achieving the aforementioned effects and providing a comfortable sleeping quality. The support member inside the mattress body 10 is a foam -formed pad body 20 for supporting the bodyweight of the user. The pad body 20 comprises an upper pad 21 and a lower pad 22 that are formed in a plate shape, such that the pad body 20 is disposed on the bottom face 13 and supports the pressure imposed on the top face 11 of the mattress body 10. The flat plate face of the upper pad 21 comprises through bores 211 passing therethrough. The lateral sides of the upper pad 21 and the lower pad 22 contacting each other comprise a plurality of upper convex blocks 215 and lower convex blocks 225 disposed at intervals, respectively. When those lateral sides of the upper pad 21 and the lower pad 22 are combined, the top faces of the upper convex blocks 215 and the lower convex blocks 225 are also combined to form a plurality of air ducts 25 inside the pad body 20.

Referring to the embodiment in Fig. 5, the top faces of the convex blocks 215 and the convex blocks 225 that are contacting each other comprises a recess 261 and recess 262, respectively, so that the recess 261 and recess 262 are combined to form the air duct 25 between the convex block 215 and the convex block 225.

The air duct between the upper pad 21 and the lower pad 22 allows the air supply of the ventilation module 50 to be efficiently distributed in the cavity 15, so as to pass the through bores 211 of the upper pad 21 to be discharged from the air outputting bores 111 of the top face 11. Notably, the air ducts 25 inside the pad body 20 are distributed in a cross arrangement. Alternatively, the air ducts 25 are allowed to be designed into a cellular arrangement, thereby providing sufficient support strength or adjusting the air flow rate inside the cavity 15.

Referring to Fig. 6 to Fig. 7, another embodiment of the air conditioning air-permeable mattress is illustrated. The support member inside the cavity 15 is a plurality of pocket springs 30 disposed in an array arrangement, so that the air flow distribution in the cavity 15 is not affected. Further, the cloth sleeve on the outer side of each pocket spring 30 may comprises through holes or be formed of an air-permeable non-woven fabric. Therefore, the purifying air provided by the ventilation module 50 is able to disinfect or sterilize the inside or the spring 31 of each pocket spring 30.

If the pocket springs 30 of different rows are disposed in a staggered arrangement, or if the middle part of the pocket spring 30 is wider than other parts thereof, when the mattress body 10 is imposed with pressure to deform, the air flow upward in the middle area of the cavity 15 may be affected. Therefore, the top face of the mattress body 10 (not shown) and/or the inner lateral side of the bottom face 13 is able to be provided with an air guiding groove 131, such that the air supply of the ventilation module 50 enters the middle area of the bottom face 13 of the cavity 15 and then flows upward, allowing the internal air to efficiently flow.

In this embodiment, the inner lateral side 123 of the side wall 12 of the mattress body 10 comprises an air guiding groove 125, so that the air supply of the ventilation module 50 efficiently flows along the surface of the air guiding groove 125 and flows around the outermost side of the support member, and is finally delivered to the middle part of the cavity 15. For achieving the effect, the air outlet 124 of the side wall 12 may be disposed in adjacent to the air guiding groove 125, such that a part of air directly flows into the air guiding groove 125, accelerating the internal circulation of the air supply in the cavity 15.

In this embodiment, the outermost side of the whole support member may have a predetermined distance with respect to the inner lateral side 123 of the side wall 12, such that the distance gap becomes a primary air duct during air intake of the ventilation module 50. Therefore, the air supply flows along the inner lateral side 123 of the side wall and flows around the outermost side of the support member. Meanwhile, the air duct inside the support member becomes a secondary air duct.

According to the types of the support member (such as a foam-formed pad, pocket spring, or connection type spring pad) in the cavity 15, the air guiding groove 125 may be selectively disposed on the top face 11 or the bottom face 13. The air guiding groove 125 may be arranged in a cross shape distribution to facilitate the fast air flow, or in a cellular distribution for creating disturbance or dispelling of air flow near the top face 11 or the bottom face 13, thus facilitating the even distribution of air flow.

In this embodiment, the top face 11 of the mattress body 10 is formed of a material of sponge mat 16, so that the air flow finally permeating from the surface fabric layer 60 is allowed to be evenly distributed without the need of a perforation process on the pad body of the top face 11 to produce air outputting bores 111.

In different embodiments, the air outlet 124 on the inner lateral side 123 of the side wall 12 is provided in a plural amount and distributed to different positions of the inner lateral side 123. Therefore, the air supply of the ventilation module 50 is able to be dispersed to the side walls 12 of different areas and enter different positions of the cavity 15. The plurality of air outlets 124 are connected with the air inlet 122 on the outer lateral side 121 of the side wall 12 through respective pipelines. Or, the side wall 12 comprises a hollow cavity inside connected with the plurality of air outlets 124 for producing a proper air supply distribution.

In various embodiments, a single-layer foam comprising air ducts may be disposed inside the cavity 15. Such arrangement does not affect the air flow in the cavity 15.

The air outputting bores 111 and the air outlet 124 of the mattress body 10 should be designed to be located away from each other as far as possible, so that the air supply of the ventilation module 50 is allowed to be distributed in the cavity 15 first after passing through the air outlet 124, and then discharged from the air outputting bore 111 on the top face 11 of the mattress body 10. In different embodiments, on the premise of achieving the aforementioned technical effects, the bottom face 13 may also be provided with an air outlet 124 connected with the cavity 15.

In other embodiments, a partition may be disposed in the middle part of the mattress body 10, so that the cavity 15 is divided into two independent cavities connected with a respective ventilation module 50. The aforementioned ventilation module 50 is able to be set with specific air supply conditions. For example, at least one of the conditions of the air supply temperature, air supply flow rate, and the air supply filtration degree in the respective cavities is allowed to be correspondingly adjusted according to actual requirements, thereby meeting the needs of the user. The partition of the cavity 15 is able to be, for example but not limited to, a foam pad or partitioning cloth.

In other embodiments, a pressure sensing module may be disposed on the support member of the mattress body 10. The pressure sensing module, temperature adjusting module, and ventilation module are electrically connected with a control module. The pressure sensing module is applied for sensing the pressure generated by the bodyweight of user, and then sends the pressure value to the control module. Meanwhile, the pressure value is also set as the air supply condition of the ventilation module 50 here in this embodiment. When the pressure sensing module senses or the control module determines that the user leaves the support member, the control module controls the ventilation module to stop supplying air or change flow rate of the air supply, or stop the temperature adjusting module from adjusting the temperature of the air supply.
