When the air bag module 11 in the mattress body 1 is inflated through the main air passage 3, the entire mattress body 1 will be deformed, which is mainly reflected in an increase in height, while the peripheral edge 3, because its function is to surround and protect the mattress body 1, has a structure that is more effective in improving stability, and therefore the peripheral edge 2 is generally provided in a micro-deformed structure that is less deformable than the mattress body 1. Through the design of above-mentioned structure, main air flue 3 can provide compensation on the problem that the deformation volume of surrounding edge 2 is not enough ingeniously.

That is, when the height of the main air duct 3 increases, the main air duct 3 will lift the surrounding edge 2 above it upward; when the height of the main air passage 3 is lowered, the height of the skirt 2 is lowered together with the height of the main air passage 3. The high realization linkage between surrounding edge 2 and main air duct 3 does benefit to and eliminates the difference in height that surrounding edge 2 and 1 surface of mattress main part were being filled the in-process of disappointing and produce, avoids 1 surface of mattress main part to produce the swell phenomenon, and then promotes the surface smoothness of mattress structure.

Preferably, in order to further eliminate the gap between the mattress body 1 and the surrounding edge 2 provided around the mattress body, the surrounding edge 2 is further provided with a stopper structure 5. As shown in figures 4 to 5, figures 4 to 5 illustrate the relationship between the restraining structure 5 and the perimeter 2 and mattress body 1. The limiting structure 5 is continuously arranged on the outer side of the surrounding edge 2 and is connected with the mattress main body 1 to limit the surrounding edge 2. The limiting structure 5 may be a limiting bracket made of an elastic material, or may be a covering layer made of a soft material such as a leather material, which is not limited herein. Specifically, the upper and lower edges of the covering layer may be connected to the mattress body 1 by bonding, riveting, stitching, or attaching with a zipper or velcro tape, so as to limit and fix the surrounding edge 2, thereby completely eliminating the gap between the mattress body 1 and the surrounding edge 2. And the main air passage 3 is arranged at the bottom of the surrounding edge 2 and is fixedly connected with the limiting structure 5 so as to realize the linkage effect with the surrounding edge 2.

And the air bags located in the first receiving grooves 131 are respectively communicated with the main air passage 3 through the auxiliary air passages 31. In this embodiment, the first receiving groove 131 is designed as a square receiving groove, and at least one airbag can be received in each square receiving groove, and the airbag is communicated with the main air passage 3 through the auxiliary air passage 31. Wherein, the auxiliary air passage 31 is attached to the side wall of the mattress main body 1. Namely, one end of the auxiliary air passage 31 is connected with the air bag, and the other end passes through the gap between the outer side wall of the mattress main body 1 and the inner side wall of the surrounding edge 2 and is communicated with the main air passage 3.

Preferably, in order to fix the position of the auxiliary air duct 31, the bushing 13 is further provided with a limit through groove at a position corresponding to each auxiliary air duct 31, through which the auxiliary air duct 31 passes.
