Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The following is combined with Figure 1-6 To further explain this application,

[0031] The embodiment of the present application discloses a combined variable temperature air cushion, comprising a lower shell 1, an upper shell 6, a fan 2, an air duct 4, an air guide plate 3 and a heating plate 5. The upper shell 6 covers the top of the lower shell 1. Four sleeves 14 are provided at the four inner corners of the lower shell 1. The four inner corners of the upper shell 6 are provided with a clamping rod 63 that is inserted into the sleeve 14. The cooperation between the clamping rod 63 and the sleeve 14 can ensure the firm connection between the upper shell 6 and the lower shell 1, and prevent the structure from loosening due to vibration or other external forces during use. Thus, a combined shell structure is formed. The design of the clamping rod 63 makes the assembly of the upper and lower shells 1 simple and quick, and also facilitates future maintenance and cleaning.

[0032] The inner chamber of the lower housing 1 is divided into a wiring trough 12 and an installation slot 13 by a partition 11; a plurality of fans 2 are provided and are arranged equidistantly and installed in the wiring trough 12. The air inlet of each fan 2 is set through the lower housing 1, and the air outlet is connected to the wide air outlet 21; the lower housing 1 is provided with a filter 15 that cooperates with the air inlet of the fan 2 to filter the air. The filter 15 can filter out dust and impurities in the inhaled air, ensuring that the blown air is clean, which is more beneficial to the health of the user. Preventing dust and impurities from entering the interior of the fan 2 reduces wear on the internal components of the fan 2 and extends the service life of the fan 2. The filter 15 can reduce the airflow noise caused by dust and impurities, improving the user experience.

[0033] The air ducts 4 are arranged in the mounting grooves 13 and every two air ducts 4 are connected to the two air outlets on a wide air vent 21. A number of air outlet nozzles 41 are arranged at equal distances on the air ducts 4; the air guide plate 3 is buckled on the outer side of each air duct 4 and an air outlet cover 31 covering the outside of the air outlet nozzle 41 is arranged at equal distances on the air guide plate 3; the air outlet cover 31 is a boss-type cover, and a number of air guide ports 32 are arranged at equal distances in a circular shape on the side of the boss-type cover. The design of the air guide ports 32 helps to evenly distribute the airflow in the air outlet cover 31, improving the blowing effect and comfort. The design of the boss-type cover and the side air guide ports 32 helps to reduce the noise during air flow and improve the user experience. A circular hole 33 is provided on the air guide plate 3 to fit the air outlet nozzle 41. The design of the circular hole 33 ensures the accurate position of the air outlet nozzle 41, helps the effective cooperation between the air guide plate 3 and the air outlet nozzle 41, and improves the air guiding efficiency. The air outlet nozzle 41 is inserted into the circular hole 33 of the air guide plate 3, which increases the connection stability between the air outlet nozzle 41 and the air guide plate 3 and prevents displacement during use.

[0034] The heating plate 5 is installed in the mounting slot 13 and inserted into the gap between two adjacent air ducts 4. A heating wire is installed within the heating plate 5. Flame-retardant needle-punched cotton is located on the inner surface of the lower housing 1 at the bottom of the heating plate 5. This cotton effectively prevents fire risks caused by the high temperatures of the heating plate 5, enhancing product safety. It also acts as a thermal insulator, reducing heat transfer to the lower housing 1 and thus protecting it from high temperatures. This helps retain heat, reduces unnecessary heat loss, and improves heating efficiency.

[0035] A plurality of interconnected inflatable bags 61 are evenly distributed on the upper shell 6 , and a plurality of vent holes 62 located outside the inflatable bags 61 are evenly distributed on the upper shell 6 .

[0036] The height of the mounting slot 13 on the lower housing 1 is lower than that of the wiring slot 12, and the upper surfaces of the air duct 4 and the heating plate 5 are flush with the upper surface of the mounting slot 13. A plurality of longitudinally arranged drain ports 64 are arranged on both sides of the upper housing 6, aligned with the mounting slot 13. This flush design allows for rapid drainage of accumulated water through the drain ports 64 when water enters the mounting slot 13, preventing it from seeping into the internal circuitry or heating plate 5 and reducing the risk of malfunction. Promptly draining accumulated water through the drain ports 64 reduces the risk of electrical short circuits or corrosion caused by moisture, thereby improving product safety.

[0037] Fan 2 is mounted within wiring trough 12, with its air inlet extending through lower housing 1 to draw in outside air. Fan 2 blows air into air duct 4. Ducts 4 are located within mounting slot 13, with each pair of ducts 4 connected to two air outlets on a wide vent 21. Ducts 4 are equipped with a plurality of air outlet nozzles 41, through which air is blown out. Air guide plate 3 is attached to the outside of duct 4, and air hood 31 is positioned outside of air outlet nozzles 41 to guide and concentrate airflow, enhancing the blowing effect.

[0038] The heating plate 5 is installed in the gap between the air ducts 4, and a heating wire is provided inside. When power is turned on, the heating wire generates heat, and the heating plate 5 heats the air to achieve heating.

[0039] By controlling the heating plate 5 and fan 2, the heating function can be used in winter and the blowing function in summer. Each component, such as the fan 2, air duct 4, air guide plate 3, and heating plate 5, is modularly designed for easy installation and maintenance.

Finally, it is led out through the air vent 62 to blow air above the inflatable bag 61.

[0041] Heating Principle: When power is applied to the heating plate 5, the internal heating wire generates heat, which in turn heats the air. This heat is then transferred through the air vents 62, thereby achieving heating. The bottom of the heating plate 5 is lined with flame-retardant needle-punched cotton, which not only acts as a thermal insulator, reducing heat transfer to the lower housing 1, but also protects the housing from high temperatures and improves heating efficiency.

[0042] By controlling the heating plate 5 and fan 2, the heating function can be used in winter and the blowing function in summer. This design allows the air mattress to provide heating or cooling according to seasonal needs. This combined variable temperature air mattress can provide users with a safe and comfortable seasonal variable temperature environment.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
