Some inflatable mattresses are equipped with multiple small air cavities. In order to ensure that the gas can only flow from the high-pressure air cavity to the low-pressure air cavity in one direction, so that the load-bearing capacity of each part of the mattress is balanced, the existing technology is to set a one-way valve in the connecting channel between adjacent air cavities. However, the existing one-way valve has the disadvantages of heavy weight, high noise, and high cost. Summary of the invention

[0020] A mattress adopts the one-way gas transmission component mentioned above.

[0021] Beneficial effects of the present invention:

[0022] The one-way gas transmission component is provided with a fixed joint and a movable joint so that the connection channel between the fixed joint and the movable joint is in a closed state. The gas in the high-pressure air cavity can enter the fixed tube through the air guide tube, and then enter the connection channel through the gap between the movable tube and the fixed tube. As the gas continues to enter, the air pressure in the connection channel and the air pressure in the gap between the movable tube and the fixed tube become larger and larger. Under the action of the air pressure, the movable part moves away from the fixed part, and the movable joint gradually moves out of the slideway. There begins to be a gap between the movable joint and the port of the connection channel, so that the gas in the connection channel is transmitted to the low-pressure air cavity through the gap. The one-way gas transmission component is provided with a limiting protrusion and a limiting hole to limit the moving distance of the movable part, thereby limiting the flow speed of the gas, so that the gas flows smoothly. When the air pressure of the two air cavities at both ends of the connection channel is the same, the movable part moves back under the action of the elastic part, and the limiting protrusion can make the movable part return to its position accurately. The gas one-way transmission component has a simple structure, light weight, and low cost, and can realize the smooth flow of gas from the high-pressure air cavity to the low-pressure air cavity. It is suitable for household items such as mattresses.

[0023] The mattress is provided with a one-way gas transmission component at the connecting channel between two adjacent air cavities, so that when the mattress is subjected to human body pressure, gas can flow one-way from the high-pressure air cavity to the low-pressure air cavity, thereby balancing the load-bearing capacity of various parts of the mattress, providing better support for the human body and helping to improve sleep quality.

[0035] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0036] like Figure 1-Figure 4 As shown, the present invention provides a one-way gas transmission component disposed inside a connecting channel 100, the connecting channel 100 is used to connect two adjacent gas cavities 200, and the one-way gas transmission component can realize the smooth transmission of gas between the two adjacent gas cavities 200. Specifically, the one-way gas transmission component includes a fixing part 1, an air guide tube 2, a movable part 3 and an elastic part 4. The fixing member 1 includes a fixing joint 11 and a fixing tube 12 which are connected to each other. A limiting protrusion 121 is provided on the fixing tube 12. The fixing joint 11 can be sealed and fixed inside the connecting channel 100. The air guide tube 2 is passed through the fixing joint 11 and the fixing tube 12. The gas in the high-pressure air cavity 200 can enter the fixing tube 12 through the air guide tube 2. The movable member 3 includes a movable joint 31 and a movable tube 32 which are connected to each other. A limiting hole 321 is provided on the movable tube 32. The movable tube 32 is slidably sleeved on the fixing tube 12. The limiting protrusion 121 extends from the limiting hole 321 and can slide axially along the connecting channel 100 in the limiting hole 321. The gas in the fixing tube 12 can enter the connecting channel 100 through the gap between the movable tube 32 and the fixing tube 12. The movable joint 31 can be sealed and slidably arranged inside the connecting channel 100. One end of the elastic member 4 is connected to the fixing joint 11, and the other end is connected to the movable joint 31.

[0037] The one-way gas transmission component is provided with a fixed joint 11 and a movable joint 31, so that the connection channel 100 between the fixed joint 11 and the movable joint 31 is in a closed state. The gas in the high-pressure air cavity 200 can enter the fixed tube 12 through the air guide tube 2, and then enter the connection channel 100 through the gap between the movable tube 32 and the fixed tube 12. As the gas continues to enter, the air pressure in the connection channel 100 and the air pressure in the gap between the movable tube 32 and the fixed tube 12 become larger and larger. The movable part 3 moves away from the fixed part 1 under the action of the air pressure, and the movable joint 31 gradually moves out of the slideway and moves toward the low-pressure air cavity 200. There begins to be a gap between the movable joint 31 and the port of the connection channel 100, and the gas in the connection channel 100 is transmitted to the low-pressure air cavity 200 through the gap. The one-way gas transmission component limits the moving distance of the movable part 3 by setting the limiting protrusion 121 and the limiting hole 321, thereby limiting the transmission speed of the gas, so that the gas cavity 200 is inflated smoothly. When the gas pressures of the two gas cavities 200 at both ends of the connecting channel 100 are the same, the movable part 3 moves back under the action of the elastic part 4, and the limiting protrusion 121 can make the movable part 3 return to its position accurately. The one-way gas transmission component has a simple structure, light weight, and low cost, and can realize the smooth flow of gas from the high-pressure gas cavity 200 to the low-pressure gas cavity 200, and is suitable for household items such as mattresses.

[0038] The movable tube 32 is sleeved on the fixed tube 12, and the limiting protrusion 121 can extend from the limiting hole 321, and the fixed tube 12 is attached to the inner wall of the movable tube 32. The gap between the movable tube 32 and the fixed tube 12 should not be too large. If the gap between the movable tube 32 and the fixed tube 12 is too large, when the movable part 3 moves under the pressure in the connecting channel 100, the movable tube 32 is easy to deviate, so that the limiting protrusion 121 escapes from the limiting hole 321 and fails to play a limiting role. Considering that the speed at which the gas flows from the gap between the movable tube 32 and the fixed tube 12 to the connecting channel 100 is slow, the movable tube 32 is also provided with an air hole 322, and the gas in the fixed tube 12 can also enter the connecting channel 100 through the air hole 322.

[0039] In order to prevent the movable member 3 from deflecting in the vertical direction as much as possible when it moves under the pressure in the connecting channel 100, two elastic members 4 are optionally provided, and the two elastic members 4 are symmetrically arranged on both sides of the movable tube 32. The elastic member 4 is selected to be a spring.

[0040] Depend on Figure 2 and Figure 3It can be seen that the fixed part 1 and the movable part 3 have the same shape, both of which are T-shaped structures, and the fixed joint 11 and the movable joint 31 have the same shape and size. The fixed joint 11 can be fixed to one end of the connecting channel 100 by adhesive, and when the movable joint 31 is sealed in the connecting channel 100, the movable joint 31 and the connecting channel 100 are interference fit. Considering the processing problem of the fixed part 1 and the movable part 3, for the convenience of processing, the fixed joint 11 and the fixed tube 12 are integrally formed, and the movable joint 31 and the movable tube 32 are integrally formed. Among them, the fixed part 1 and the movable part 3 are both made of plastic material. Specifically, ABS plastic (Acrylonitrile Butadiene Styrene plastic) with a certain hardness and good comprehensive performance is selected.

[0041] The present invention also provides a mattress using the above-mentioned one-way gas transmission component, such as Figure 5 As shown, the mattress includes a plurality of air chambers 10 arranged in parallel, each air chamber 10 is provided with a plurality of air cavities 200, and the gas one-way transmission component is provided at the connecting channel 100 between two adjacent air cavities 200. Figure 5 A simple diagram is used to represent the one-way gas transfer component. Since the one-way gas transfer component can only realize one-way gas transfer, the mattress is also provided with an airbag 300, and the airbag 300 is connected to the first air cavity 200 and the end air cavity 200 in each air chamber 10. A reflux channel 400 is also provided in the air chamber 10, and the gas in the end air cavity 200 can flow to the airbag 300 through the reflux channel 400, so that a gas circulation loop is formed between the air chamber 10 and the airbag 300. When a human body lies on the mattress, the main stress points of the mattress include the buttocks and shoulders, and the air pressure in the air cavity 200 corresponding to the buttocks and shoulders increases, and the gas flows to the adjacent air cavity 200 with relatively smaller air pressure through the one-way gas transfer component, so that the load-bearing capacity of each part of the mattress is balanced, better support is provided for the human body, and it helps to improve the quality of sleep.
