[0002] As living standards improve, people increasingly need mattresses that provide healthy and comfortable sleep. Currently, there are many different types and functions of mattresses on the market. Among them, air mattresses are favored by users due to their convenience, portability, and lightweight nature, and are now widely used in various scenarios such as home life, outdoor camping, and leisure activities. However, air mattresses with a single air-filled structure currently on the market have problems such as a hard frame, low comfort, susceptibility to being scratched by sharp objects, and difficulty in cleaning after getting dirty. At the same time, air mattresses with a single air-filled structure also have the limitation of limited usage scenarios; for example, car mattresses can only be used inside a car, and outdoor mattresses can only be used outdoors, failing to meet the diverse application needs of users in various scenarios.

[0046] Figure 1A An exploded view of one embodiment of the air-filled bed of this application is shown. Figure 1B A schematic diagram of the combined state of an embodiment of the air bed of this application is shown. Figure 1C It shows Figure 1A A schematic cross-sectional view of the combined state of the air-filled bed. Figure 1D It shows Figure 1A A diagram illustrating the inflatable mattress used as a car mattress. (See attached image.) Figure 1A , 1BIn this embodiment, an air mattress is provided, comprising a first inflatable gas 100, a second inflatable gas 200, and a mattress cover 300. The first inflatable gas 100 includes a first piece 1201 and a second piece 1202, wherein the first piece 1201 and the second piece 1202 are disposed opposite to each other, and the first piece 1201 and the second piece 1202 together form the first outer wall of the first inflatable gas 100, and together enclose a first air chamber 120, that is, the first air chamber 120 is defined by the first outer wall. In other embodiments of this embodiment, the first inflatable gas 100 of the air mattress may further include a first side piece 1203, wherein the first side piece 1203 includes an upper end connected to the first piece 1201 and a lower end connected to the second piece 1202, and the first piece 1201, the second piece 1202, and the first side piece 1203 together form the first outer wall of the first inflatable gas 100, and together enclose a first air chamber 120, that is, the first air chamber 120 is defined by the first outer wall. In this embodiment, the first piece 1201 of the first outer wall has a concave-convex portion 111, and the second piece 1202 is relatively flat. The second gas filling 200 includes a third piece 2201 and a fourth piece 2202, wherein the third piece 2201 and the fourth piece 2202 are disposed opposite to each other, and the third piece 2201 and the fourth piece 2202 together form the second outer wall of the second gas filling 200, and together enclose to form the second air chamber 220, that is, the second air chamber 220 is defined by the second outer wall, and the third piece 2201 and the fourth piece 2202 of the second outer wall are relatively flat. In some embodiments, the second gas filling 200 may further include a second side piece (not shown in the figure), and the third piece 2201, the fourth piece 2202 and the second side piece (not shown in the figure) together form the second outer wall of the second gas filling 200, and together enclose to form the second air chamber 220. Exemplarily, the first side piece 1203 or the second side piece (not shown) can be formed by connecting one piece of material end to end, or by welding four pieces of material end to end; this application does not impose any limitation on this. In this embodiment, the second inflation gas 200 is disposed above the first inflation gas 100 and is detachably connected to the first inflation gas 100, that is, the third piece 2201 of the second outer wall of the second inflation gas 200 is attached to and detachably connected to the second piece 1202 of the first outer wall of the first inflation gas 100. The bed cover 300 is attached to the fourth piece 2202 of the second inflation gas 200 and covers the second inflation gas 200 and the first inflation gas 100, that is, the bed cover 300 covers the second inflation gas 200 and the first inflation gas 100, and the second inflation gas 200 is disposed between the bed cover 300 and the first inflation gas 100. The bottom of the first gas filling 100, i.e., the first piece 1201 of the first outer wall, is provided with a protrusion 111. When the air bed is in use, the first gas filling 100 with the protrusion 111 will cooperate with the support carrier supporting the air bed, for example, as... Figure 1D As shown, when the air mattress is used as a car mattress, the first piece 1201 of the first inflation 100 contacts the car seat 701. Figure 1D(The image shows the rear car seat 701 in its folded state). The concave and convex portions 111 of the first air-filled 100 will match the concave and convex portions of the car seat 701. The concave and convex portions 111 can make the first air-filled 100 level during use, that is, make the second piece 1202 of the first outer wall of the first air-filled 100 remain in a horizontal state, and at the same time make the third piece 2201 and the fourth piece 2202 of the second outer wall of the second air-filled 200 located above the first air-filled 100 also remain in a horizontal state. This allows the first air-filled 100 to provide a flat placement platform for the second air-filled 200, so that the user can lie flat on the second air-filled 200, thereby improving the comfort and stability of the air mattress. In this embodiment, the second air chamber 220 of the second inflation 200 is filled with a sponge filling portion 210. That is, the sponge filling portion 210 is disposed within the second air chamber 220 of the second inflation 200. The material of the sponge filling portion 210 includes, but is not limited to, high-resilience sponge, slow-resilience sponge, latex sponge, etc. Adding the sponge filling portion 210 can improve the comfort of the air mattress and enhance its protection against scratches. It is understood that the second air chamber 220 of the second inflation 200 may not include the sponge filling portion 210, or may be partially filled with the sponge filling portion 210, etc. This embodiment does not impose limitations on this. In this embodiment, the bed cover 300 is attached to the fourth piece 2202 of the second inflation gas 200 and covers both the second inflation gas 200 and the first inflation gas 100. That is, the bed cover 300 is positioned over both the second inflation gas 200 and the first inflation gas 100, with the second inflation gas 200 located between the bed cover 300 and the first inflation gas 100. This prevents relative displacement between the second inflation gas 200 and the first inflation gas 100, which are filled with sponge padding 210. It also prevents the areas covered by the bed cover 300 from being scratched or damaged, and provides dust protection. If soiled, the bed cover 300 can be removed separately for cleaning, making the process faster and more convenient. The first inflation gas 100 is equipped with a first air valve 112 for inflation and deflation. The second inflation gas 200 is equipped with a second air valve 211 for inflation and deflation. The air mattress cover 300 is provided with a first through hole 311. The position of the first through hole 311 is adapted to the position of the second air valve 211 on the second air filling 200, so that when the air mattress is in the assembled state, the second air valve 211 on the second air filling 200 can be exposed through the first through hole 311 on the air mattress cover 300. This makes it more convenient to perform the inflation and deflation operations on the second air filling 200 without having to remove the air mattress cover 300.The second gas filling 200 and the first gas filling 100 are detachably connected by a first connector 400. In this embodiment, the first connector 400 is a male and female buckle, that is, the first connector 400 includes a female buckle 411 and a male buckle 412. The female buckle 411 and the male buckle 412 are paired fasteners. The male buckle 412 of the male and female buckle is provided on the first gas filling 100, and the female buckle 411 of the male and female buckle is provided on the second gas filling 200. Alternatively, the male buckle 412 of the male and female buckle is provided on the second gas filling 200, and the female buckle 411 of the male and female buckle is provided on the first gas filling 100. That is, the male buckle 412 and the female buckle 411 of the male and female buckle are respectively embedded in one of the second gas filling 200 and the first gas filling 100. Through the first connector 400, namely through the female buckle 411 and the male buckle 412, the second gas inflator 200 can be more securely and detachably connected to the first gas inflator 100, so that after the second gas inflator 200 and the first gas inflator 100 are connected and fixed, their positions are relatively fixed and they are not prone to relative displacement. In some embodiments, the first gas inflator 100 and the second gas inflator 200 may also be without the first connector 400, that is, the third piece 2201 of the second gas inflator 200 is directly attached to the second piece 1202 of the first gas inflator 100. In this embodiment, the mattress cover 300 includes an outer periphery, which is detachably connected to the first inflation gas 100 or the second inflation gas 200. Specifically, the mattress cover 300 adheres to the fourth piece 2202 of the second inflation gas 200 and covers both the second inflation gas 200 and the first inflation gas 100. It is detachably connected to either the first inflation gas 100 or the second inflation gas 200 via its outer periphery. Alternatively, the mattress cover 300 can directly cover the upper surface of the second inflation gas 200 and cover both the first inflation gas 100 and the second inflation gas 200. In this case, the mattress cover 300 does not need to be connected to the first inflation gas 100 or the second inflation gas 200 via a connector; it directly adheres to the fourth piece 2202 of the second inflation gas 200 and covers both the second inflation gas 200 and the first inflation gas 100. The mattress cover 300 is installed using a non-connector type covering method.

[0047] Figure 2A An exploded view of another embodiment of the air bed of this application is shown. Figure 2B The air bed of this application is shown. Figure 2A A schematic diagram of the combined state profile. (See attached diagram.) Figure 2A and Figure 2B In this application, the air bed in this embodiment is similar to the one described above. Figures 1A to 1DThe structure of the air mattress described herein is similar, and the identical parts will not be repeated. The only difference is that the air mattress in this embodiment also includes a spacer 500, which is disposed above the second inflatable gas 200 and between the cover 300 and the second inflatable gas 200. The material of the spacer 500 includes, but is not limited to, cotton, linen, textiles, sponge, silicone, etc., and can be a material with heat insulation function, or waterproof material such as PVC / PEVA. The cover 300 covers the upper surface of the spacer 500, that is, the cover 300 covers the spacer 500, the second inflatable gas 200 and the first inflatable gas 100. The spacer 500 can be a soft, skin-friendly material, which can further improve the comfort of the air mattress and further enhance the protection against scratches on the second inflatable gas 200. The spacer 500 is provided with a second through hole 511. The position of the second through hole 511 is adapted to the position of the first through hole 311 and the second air valve 211 on the second air filling 200, so that when the air bed is in the assembled state, the second air valve 211 on the second air filling 200 can be exposed from the first through hole 311 and the second through hole 511, so that the second air filling 200 can be easily inflated or deflated without disassembling the bed cover 300.

Figure 3A A schematic diagram of the cross-section of the separated state. Figure 3C The air bed of this application is shown. Figure 3A A schematic diagram of the structure of the first connecting component. Figure 3D This application shows that Figure 3A and Figure 3B A cross-sectional schematic diagram of the second filling gas after it has been separately separated. (See also...) Figures 3A to 3D In this application, the air bed in this embodiment is the same as the one mentioned above. Figures 1A to 1DThe structure of the air bed described in the previous embodiment is similar, and the same parts will not be repeated. The only difference is that the first connecting member 400 is different from the male-female snap connection structure in the embodiment of the first air bed. In this embodiment, the first connecting member 400 is a valve connection structure. In this embodiment, the first connecting member 400 includes a third air valve 600 and a connecting valve 614. The third air valve 600 is a one-way valve and is disposed on the second inflation gas 200. The connecting valve 614 is a conduction valve and is disposed on the first inflation gas 100. The third air valve 600 and the connecting valve 614 are detachably connected. The third air valve 600 includes a valve body 611, a valve cover 612, and a lifting part 613. The valve body 611 is fixed on the second inflation gas 200. The valve cover 612 and the valve body 611 of the third air valve 600 are flexibly connected by a flexible connecting strip 615. The lifting part 613 extends from the valve cover 612 of the third air valve 600. In this embodiment, the second gas filling 200 can be more securely and detachably connected to the first gas filling 100 through the first connector 400, that is, through the third gas valve 600 and the connecting valve 614, so that after the second gas filling 200 and the first gas filling 100 are connected and fixed, the positions of the second gas filling 200 and the first gas filling 100 are relatively fixed and are not easy to be displaced.

[0049] In this embodiment, when the second gas filling gas 200 is connected to the first gas filling gas 100, the valve body 611 of the third gas valve 600 is matched and fixedly connected to the connecting valve 614, thereby improving the stability of the connection between the second gas filling gas 200 and the first gas filling gas 100. Furthermore, after the third air valve 600 and the connecting valve 614 are matched and fixedly connected, the gas in the first filling gas 100 can enter the second air chamber of the second filling gas 200 through the third air valve 600. The first filling gas 100 can fill the second filling gas 200 through the connecting valve 614 and the third air valve 600. That is, when the first filling gas 100 is filled, the second filling gas 200 can be filled at the same time through the third air valve 600 and the connecting valve 614. In this way, it is possible to achieve the goal of filling the first filling gas 100 and the second filling gas 200 simultaneously only through the first air valve 112 on the first filling gas 100. This simplifies the operation process and ensures the overall structural stability of the air bed through automatic pressure balance between the first filling gas 100 and the second filling gas 200. At the same time, it reduces the risk of air leakage and maintenance costs caused by the multi-valve design, thereby significantly improving the convenience of use and product reliability.

[0050] In this embodiment, when the second inflation gas 200 separates from the first inflation gas 100, the user places the valve cover 612 onto the valve body 611 of the third gas valve 600. This ensures that the second inflation gas 200 remains airtight and in an inflated state after separation from the first inflation gas 100, allowing for direct use independently. In this embodiment, the lifting part 613 facilitates the operation of placing the valve cover 612 onto the third gas valve 600.

[0051] Furthermore, since the third gas valve 600 is a one-way valve, when the valve cover 612 of the third gas valve 600 is not yet closed on the valve body 611, gas can only flow through the third gas valve 600 from the outside of the second gas filling 200 to the second gas chamber 220 of the second gas filling 200, and cannot flow from the inside of the second gas chamber 220 of the second gas filling 200 to the outside of the second gas filling 200. Therefore, when the second gas filling 200 is separated from the first gas filling 100, the gas in the second gas chamber 220 of the second gas filling 200 will not flow out of the second gas filling 200. Even if the user completes the action of "closing the valve cover 612 on the valve body 611 of the third gas valve 600" relatively slowly, the second gas filling 200 can still maintain airtightness for a long time due to the one-way valve characteristic of the third gas valve 600.

[0052] After the second inflation gas 200 separates from the first inflation gas 100, the second inflation gas 200 will not leak air, meaning there is no need to re-inflate the second inflation gas 200. The second inflation gas 200 can be used directly as a mattress on its own. At this time, the mattress is suitable for camping, indoor use and other scenarios, thus meeting the needs of users for multiple scenarios and improving the convenience of use, saving time and effort.

[0053] In this application, when the second filling gas 200 needs to be vented, the user can pull out the third air valve 600 (one-way valve) of the second filling gas 200 to vent it, that is, the third air valve 600 is not in operation, allowing the air inside the second filling gas 200 to flow out freely. Alternatively, the second filling gas 200 can be vented externally by using the second air valve 211 or other air valves (not shown in the figure) provided on the second filling gas 200.

[0054] In other embodiments of this example, a spacer 500 may also be included, the structure, placement, material, and function of which are the same as described above. Figure 2A and 2B The spacer 500 in the embodiments of the air bed described herein is the same and will not be described again.

[0055] Figure 4A A schematic diagram of the combined state of another embodiment of the air bed of this application is shown. Figure 4B This application shows Figure 4A A magnified view of the center zipper. (See attached image.) Figure 4A and Figure 4BThe air mattress in this embodiment also includes a second connector 410, which detachably connects the mattress cover 300 and the first inflatable gas 100. In this embodiment, the second connector 410 is a zipper 413, with the zipper teeth of the zipper 413 respectively located on the mattress cover 300 and the first inflatable gas 100. Through the second connector 410, i.e., through the zipper 413, the mattress cover 300 can be more securely and detachably connected to the first inflatable gas 100, thereby further enhancing the fixing and protection of the mattress cover 300 for the second inflatable gas 200 and the first inflatable gas 100. The second connector 410 ensures that after the mattress cover 300 and the first inflatable gas 100 are connected and fixed, the positions of the mattress cover 300, the second inflatable gas 200, and the first inflatable gas 100 are relatively fixed and not prone to relative displacement. In this application, the structure of other parts of the air mattress in this embodiment can be any of the air mattresses described in the preceding embodiments.

[0056] Figure 5A A schematic diagram of the combined state of another embodiment of the air bed of this application is shown. Figure 5B This application shows Figure 5A Enlarged view of a portion of the hook-and-loop fastener. (See attached image) Figure 5A and Figure 5B The structure of the air bed in this embodiment is basically similar to that of the air bed embodiments described above. The identical parts will not be repeated. The only difference is that the second connecting member 410 differs from the zipper 413 structure in the air bed embodiments described above. In this embodiment, the second connecting member 410 is a hook-and-loop fastener 414, which includes a hook and a fixing ring, respectively disposed on the bed cover 300 and the first inflatable gas 100. Through the second connecting member 410, i.e., through the hook-and-loop fastener 414, the bed cover 300 can be more securely and detachably connected to the first inflatable gas 100, thereby further enhancing the fixing and protection of the bed cover 300 for the second inflatable gas 200 and the first inflatable gas 100. The second connecting member 410 ensures that after the bed cover 300 and the first inflatable gas 100 are connected and fixed, the positions of the bed cover 300, the second inflatable gas 200, and the first inflatable gas 100 are relatively fixed and not prone to relative displacement.

[0057] Figure 6A A schematic diagram of the combined state of another embodiment of the air bed of this application is shown. Figure 6B This application shows Figure 6A A magnified view of the center clasp. (See attached image.) Figure 6A and Figure 6BThe structure of the air bed in this embodiment is basically similar to that of the air bed embodiments described above, and the same parts will not be repeated. The only difference is that the second connecting member 410 is different from the zipper 413 or hook and loop fastener 414 in the air bed embodiments described above. In this embodiment, the second connecting member 410 is a snap fastener 415, which includes a male snap fastener and a female snap fastener. The male snap fastener and the female snap fastener are respectively provided on the bed cover 300 and the first inflatable gas 100. Through the second connecting member 410, that is, through the snap fastener 415, the bed cover 300 can be more firmly and detachably connected to the first inflatable gas 100, thereby further improving the fixing and protection of the bed cover 300 for the second inflatable gas 200 and the first inflatable gas 100. The second connecting member 410 makes the positions of the bed cover 300, the second inflatable gas 200 and the first inflatable gas 100 relatively fixed and not easy to undergo relative displacement after the bed cover 300 and the first inflatable gas 100 are connected and fixed.

[0058] In other embodiments of this application, those skilled in the art will understand that the second connecting member 410 in the air mattress of this application can also be disposed on the mattress cover 300 and the second inflatable gas 200, that is, the mattress cover 300 and the second inflatable gas 200 are detachably connected by the second connecting member 410. The specific structure will not be described in detail. The second connecting member 410 ensures that after the mattress cover 300 and the second inflatable gas 200 are connected and fixed, the positions of the mattress cover 300 and the second inflatable gas 200 are relatively fixed and not easily subject to relative displacement.
