DETAILED DESCRIPTION OF THE EMBODIMENTS

The specific embodiments of the present disclosure are described in details in combination with the drawings.

This specific embodiment is only an explanation of the present disclosure, and it is not a limitation to the present disclosure. After reading this specification, those skilled in the art can make modifications to this embodiment that do not create any contribution as needed, but the modifications shall be protected by the patent law within the scope of the claims of the present disclosure.

This embodiment relates to an air mattress, including a mattress main body 99 and an inflation and deflation device 3.

The mattress main body 99 is provided with an inflation chamber 1 and a first airflow channel 2. The inflation chamber 1 is a place for inflating and deflating the air mattress. The first airflow channel 2 is a place where an inflation airflow and a deflation airflow pass through. The inflation chamber 1 is communicated to the first airflow channel 2. The mattress main body 99 includes a first mattress inner wall 93 and a second mattress inner wall 94. A number of third airflow channels 92 are arranged between the first mattress inner wall 93 and the second mattress inner wall 94, so that the mattress main body 99 can be more stable in inflation and deflation states.

In this embodiment, a material of the third airflow channels 92 is a plastic material. The third airflow channels 92 are uniformly distributed between the first mattress inner wall 93 and the second mattress inner wall 94. Two ends of first connecting walls 95 and two ends of second connecting walls 96 of the third airflow channels 92 are fixed to the first mattress inner wall 93 and the second mattress inner wall 94, respectively. In the inflation state, the inflation airflow from the first airflow channel 2 passes through the inflation chamber 1 and the third airflow channels 92, so that the third airflow channels 92 and the air mattress expand; the first mattress inner wall 93 and the second mattress inner wall 94 pull the first connecting walls 95 and the second connecting walls 96 of the third airflow channels 92 to move, which prevents deformation of the air mattress caused by non-uniform air pressure in the air mattress in the inflation state. In this way, pressures on the third airflow channels 92 are the same. Due to the fixed connection between the first connecting walls 95 as well as the second connecting walls 96 and the first mattress inner wall 93 as well as the second mattress inner wall 94, if deformation occurs in the inflation state, both the first connecting walls 95 and the second connecting walls 96 in the third airflow channels 92 will pull the first mattress inner wall 93 and the second mattress inner wall 94, which prevents the influence on the visual effect and a poor use effect caused by an uneven surface of the mattress main body 99 due to non-uniform stress on the mattress main body 99. In the deflation state, due to the fixed connection between the first connecting walls 95 as well as the second connecting walls 96 and the first mattress inner wall 93 as well as the second mattress inner wall 94, if air is discharged from the first airflow channel 2, a volume of the air mattress decreases, and a distance between the first mattress inner wall 93 and the second mattress inner wall 94 decreases, causing deformation of the first connecting walls 95 and second connecting walls 96 of the third airflow channels 92. As the pressures in the third airflow channels 92 are the same, when the deformation occurs, the first connecting walls 95 and second connecting wall 96 of the third airflow channels 92 deform at the same speed. Therefore, in the deflation state, the surface of the air mattress remains flat. In a reset state, the first airflow channel 2 is closed, the pressure in the inflation chamber 1 remains unchanged, and the third airflow channels 92 remains stationary with the air mattress.

In the inflation state, the inflation switch 383 is triggered, and the inflation push rod 387 passes through the inflation through hole 41 and the inflation opening. The inflation guide slope 395 pushes the pushing plate 4 towards the conducting switch 35, causing the pushing plate 4 to push the conducting switch 35. When the driving device 31 starts to work, and the first elastic member 6 is compressed towards the mounting housing 37. The second spring 388 abuts against the fixed plate 5 and is compressed. The elastic reset force generated by the compression of the second spring 388 can press the pushing plate 4 into the first locking groove 394, and the first locking groove 394 is clamped on the outer wall of the inflation through hole 41.
