[0002] Pneumatic waist dragging is a phenomenon in which the membranes of the multi-layer airbags used in pneumatic massage may stick together during use. As the pressure and air volume reach a certain level, the cavity away from the air source suddenly bounces up and emits a corresponding noise. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, the utility model designs a multi-layer air bag membrane structure with anti-adhesion. An auxiliary membrane is added in the air cavity, which passes through the airway to separate different chambers, thereby playing a good role in isolation and anti-adhesion.

[0004] In order to achieve the above-mentioned purpose, a multi-layer air bag diaphragm structure with anti-adhesion is designed, including a welded diaphragm on the outside of the upper cavity, a welded diaphragm on the inside of the upper cavity, a welded diaphragm on the inside of the lower cavity, and a welded diaphragm on the outside of the lower cavity. The upper inner cavity welded diaphragm, the lower inner cavity welded diaphragm, and the lower outer cavity welded diaphragm are arranged in sequence below the upper outer cavity welded diaphragm. The surface of the upper inner cavity welded diaphragm is provided with a cavity vent hole 1, and the surface of the lower inner cavity diaphragm is provided with a cavity vent hole 2. One end of an auxiliary layer diaphragm is provided between the upper outer cavity welded diaphragm and the upper inner cavity welded diaphragm, and the other end of the auxiliary layer diaphragm passes through cavity vent hole 1 and cavity vent hole 2 respectively, and is located between the lower inner cavity welded diaphragm and the lower outer cavity welded diaphragm.

[0005] The auxiliary layer membrane includes a membrane 1, a membrane 2, and a connecting piece. The membrane 1 and the membrane 2 are connected by the connecting piece. The shapes of the membrane 1 and the membrane 2 are both arrow-shaped.

[0006] The diaphragm 1 is located between the welded diaphragm outside the upper cavity and the welded diaphragm inside the upper cavity, and the diaphragm 2 is located between the welded diaphragm inside the lower cavity and the welded diaphragm outside the lower cavity.

[0007] The diaphragm 1, diaphragm 2 and connecting piece are an integrated structure.

[0008] A hose is provided on one side between the welding diaphragm on the inner side of the lower cavity and the welding diaphragm on the outer side of the lower cavity.

[0009] The edges around the upper cavity outer welding diaphragm and the upper cavity inner welding diaphragm, the upper cavity inner welding diaphragm and the lower cavity inner welding diaphragm, and the lower cavity inner welding diaphragm and the lower cavity outer welding diaphragm are fixed by welding.

[0010] One end of the hose is located inside the lower cavity and between the welded diaphragm and the welded diaphragm outside the lower cavity, and the other end of the hose is located outside the lower cavity and between the welded diaphragm and the welded diaphragm outside the lower cavity.

[0011] Compared with the prior art, the utility model has a simple structure and is easy to install. The auxiliary diaphragm divides different chambers, plays a good isolation and anti-adhesion role, and effectively reduces noise. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figures 1 to 2 As shown, the upper cavity inner side welding diaphragm 2, the lower cavity inner side welding diaphragm 3, and the lower cavity outer side welding diaphragm 4 are arranged in sequence below the upper cavity outer side welding diaphragm 1. The surface of the upper cavity inner side welding diaphragm 2 is provided with a cavity vent hole 1 5, and the surface of the lower cavity inner side welding diaphragm 3 is provided with a cavity vent hole 2 6. One end of an auxiliary layer diaphragm 7 is provided between the upper cavity outer side welding diaphragm 1 and the upper cavity inner side welding diaphragm 2. The other end of the auxiliary layer diaphragm 7 passes through the cavity vent hole 1 5 and the cavity vent hole 2 6 respectively, and is located between the lower cavity inner side welding diaphragm 3 and the lower cavity outer side welding diaphragm 4.

[0020] The auxiliary layer membrane 7 includes a membrane 1 7.1, a membrane 2 7.2, and a connecting piece 7.3. The membrane 1 7.1 and the membrane 2 7.2 are connected by the connecting piece 7.3. The shapes of the membrane 1 7.1 and the membrane 2 7.2 are both arrow-shaped.

[0021] Diaphragm 1 7.1 is located between diaphragm 1 welded outside the upper cavity and diaphragm 2 welded inside the upper cavity, and diaphragm 2 7.2 is located between diaphragm 3 welded inside the lower cavity and diaphragm 4 welded outside the lower cavity.

[0022] The diaphragm 1 7.1, the diaphragm 2 7.2 and the connecting piece 7.3 are an integrated structure.

[0023] A hose 8 is provided on one side between the welding diaphragm 3 on the inner side of the lower cavity and the welding diaphragm 4 on the outer side of the lower cavity.

[0024] The edges around the upper cavity outer welding diaphragm 1 and the upper cavity inner welding diaphragm 2, the upper cavity inner welding diaphragm 2 and the lower cavity inner welding diaphragm 3, and the lower cavity inner welding diaphragm 3 and the lower cavity outer welding diaphragm 4 are fixed by welding.

[0025] One end of the hose 8 is located inside the lower cavity inner welding diaphragm 3 and the lower cavity outer welding diaphragm 4, and the other end of the hose 8 is located outside the lower cavity inner welding diaphragm 3 and the lower cavity outer welding diaphragm 4.

[0026] When the present invention is used, an auxiliary layer diaphragm 7 is added to the cavity vent 1 5 and the cavity vent 2 6 at the connection between the upper cavity inner side welding diaphragm 2 and the lower cavity inner side welding diaphragm 3, such as Figure 3 As shown, the arrow portion of the auxiliary layer membrane 7 passes through the cavity vent hole 1 5 and the cavity vent hole 2 6 respectively.
