Background With the development of massage equipment, the multi-layer air bag structure is widely applied due to the advantages of partition pressure application, dynamic adjustment and the like. The traditional massage air bag is formed by the diaphragms overlapped up and down to form an inflation cavity, and the linkage inflation of multiple cavities is realized through the vent holes of the connecting parts. However, such structures present the following technical pain points: The membrane adhesion problem is that in a non-inflated state, the membranes of adjacent air bags are easy to adsorb adhesion due to smooth and tight adhesion of the surfaces, and the membrane adhesion is more remarkable in a humid environment. When the inflatable bag is inflated for the first time, larger static friction force needs to be overcome, so that starting is delayed, and the massage response speed is seriously influenced. For example, CN 221770752U, a coarse structure in the air bag massage device can prevent the upper and lower diaphragms from adhering to block the vent hole, so as to avoid affecting the use experience of the massage device, however, although the coarse structure in the patent can reduce the contact area, the contact between the plane top surface and the corresponding connecting piece is still surface contact, and the improvement of friction coefficient is limited.
