Structure for preventing adhesion of upper film and lower film of massage air bag

Abstract

The utility model provides a structure for preventing adhesion of upper and lower membranes of a massage air bag, the massage air bag is formed by stacking a plurality of layers of air bags up and down, the air bag comprises a first membrane and a second membrane, the edges of the first membrane and the second membrane are adhered to each other, so that an inflation chamber is formed between the first membrane and the second membrane; adjacent air bags are connected through a connecting part, a vent hole is formed in the connecting part and used for inflating an inflation cavity communicated with the vent hole, a plurality of first jacking blocks distributed at intervals are arranged on the connecting part around the vent hole, a first inclined face inclining downwards outwards from the vent hole is arranged at the top of each first jacking block, and the first inclined faces incline downwards outwards from the vent holes in the non-inflation state. The connecting parts of the adjacent air bags are in point contact through the inclined faces of the first inclined faces, the contact area of the top faces of the first jacking blocks and the connecting parts stacked on the upper portions is reduced, friction is reduced, and the jacking speed is increased.
