As shown in fig. 2 and 3, an inner conductive layer 4 is sleeved at the bottom of the inner cavity of the surface layer adsorption bowl 2, and specifically, the inner conductive layer 4 is sleeved in the inner cavity of the inner layer flanging 12.
In fig. 3, a gap exists between the inner conductive layer 4 and the bottom surface of the self-sealing conductive adsorption bowl, specifically, a cross-shaped ventilation groove 10 as shown in fig. 5 is arranged on the lower bottom surface of the inner conductive layer 4, and when the inner conductive layer 4 and the bottom surface of the self-sealing conductive adsorption bowl are hermetically sleeved, the cross-shaped ventilation groove 10 is a closed space.
The electric tube 1 is fixed on one side of the self-sealing conductive adsorption bowl bottom surface, and the inner end of the electric tube 1 is communicated with the ventilation groove 10. The center of the inner conductive layer 4 has a center protrusion 7 protruding upward, and as shown in fig. 3 and 4, an inner annular protrusion 8 and an outer annular protrusion 9 protruding upward are sequentially provided outside the center protrusion 7, so that an annular space exists between the inner annular protrusion 8 and the outer annular protrusion 9, and a vent hole 11 communicating with the vent groove 10 is provided at the bottom of the annular space. In fig. 3, the height of the inner annular bulge 8 is lower than that of the outer annular bulge 9, the inner cavity of the outer annular bulge 9 is matched and sleeved with the sealing sheet 5, wherein the center of the sealing sheet 5 is provided with a through hole which is sleeved outside the central bulge 7, and the inner wall of the sealing sheet 5 is supported on the surface of the inner annular bulge.
As shown in fig. 3 and 5, the inner conductive layer 4 and the bottom surface of the surface layer adsorption bowl are integrally formed or are in a combined and sleeved relation, the lower bottom surface of the inner conductive layer 4 is close to the outer edge, and two layers of annular grooves 6 are formed, so that the thickness of the inner conductive layer is reduced, deformation is convenient to occur, the suction performance of the inner conductive layer 4 and the bottom surface of the self-sealing conductive adsorption bowl can be improved, and separation of the inner conductive layer 4 and the self-sealing conductive adsorption bowl is avoided. Or the inner conductive layer 4 is formed by compression molding, and the inner conductive layer 4, the conductive air pipe 1 and the surface adsorption bowl 2 are integrally fused together by heating and pressurizing.
The wood pulp cotton 3 is sleeved above the sealing sheet 5, specifically in the inner cavity of the inner layer flanging 12, and the bottom surface of the wood pulp cotton 3 is contacted with the sealing sheet 5.
Based on the scheme, the conductive air pipe 1 and the surface layer adsorption bowl 2 of the adsorption bowl adopt an integral injection molding process, so that the conductive air pipe 1 and the surface layer adsorption bowl 2 are integrated; the inner conductive layer 4 is formed by compression molding, and the inner conductive layer 4, the conductive air pipe 1 and the surface adsorption bowl 2 are integrally fused together by heating and pressurizing; the sealing sheet 5 is mounted at the central protrusion 7 of the inner conductive layer 4 through the central perforation; the wood pulp cotton 3 is arranged inside the surface adsorption bowl 2 through the inner layer flanging 12.
The conductive air pipe 1 adopts a hollow metal conduit, the surface adsorption bowl 2 is made of insulating silica gel, and the inner conductive layer 4 is made of silicon rubber with inner cavity containing metal powder, graphite powder or other conductive materials. The conductive air pipe 1 and the inner conductive layer 4 are contacted with each other after being molded to form a whole, and can conduct electricity. The wet wood pulp cotton is clamped into the inner flanging 12 of the surface adsorption bowl 2 and is communicated with the inner conductive layer of the inner conductive layer 4 to form a whole for conducting electricity.
The center of the sealing piece 5 is provided with a round perforation, and the round edge at the outer side is provided with an arc angle; the lower part of the inner conductive layer 4 has a central protrusion 7, an inner annular protrusion 8 and an outer annular protrusion 9. The center bulge 7 is narrow at the upper part and wide at the lower part to form a stop part, the center round through hole of the sealing sheet 5 is sleeved into the stop part of the center bulge 7, and the sealing sheet 5 is prevented from falling off through the wide edge of the center bulge; the inner annular protrusion 8 is fitted to the upper surface of the sealing plate 5, and the sealing (metal) plate is positioned at the corresponding position by the center protrusion 7 and the inner annular protrusion 8.

The hollow metal conduit of the conductive air pipe 1 is connected with the vent hole 11 on the inner conductive layer 4 to form an air path.
Working principle: when the adsorption bowl does not work, the adsorption bowl does not need to be ventilated, and the adsorption bowl is in a natural state and is not deformed as a whole. The joint of the round edge of the sealing piece 5 and the inner layer of the outer annular bulge 9 isolates the inner space of the adsorption bowl from the vent hole 11, and gas cannot flow out through the vent hole 11 so as to form a seal. Meanwhile, if the air pump is used for exhausting air through the conductive air pipe, negative pressure is formed on the upper surface of the inner conductive layer 4, so that the sealing piece 5 is in closer contact with the inner conductive layer 4, and air leakage is less prone to occurring. The characteristic ensures that the pressure condition of other working adsorption bowls cannot be influenced and changed due to the air leakage problem.
When the adsorption bowl needs to work, the adsorption bowl needs to be attached to the human body, and meanwhile, the middle area of the adsorption bowl is pressed by hands. The inner conductive layer 4 is deformed due to the pressing of fingers, the lower part of the annular bulge 9 is opened, a gap is formed between the sealing piece 5 and the annular bulge 9, the inside of the adsorption bowl is communicated with the vent hole 11, and air in the adsorption bowl is discharged through the vent hole 11, the vent groove 10 and the conductive air pipe 1. After the air is exhausted, negative pressure is formed in the adsorption bowl, so that the adsorption bowl tightly presses wood pulp cotton to be tightly attached to a human body for electric stimulation.
Based on the integrated structural form of the silica gel and the conductive layer in the scheme, the process is optimized, the metal electrode is reduced, and the human body is more easily attached; the self-sealing structure is adopted, so that the air channel is closed when the working is not needed, the air leakage is reduced, the adsorption performance of other branches is improved, and the noise is reduced; the main body is soft rubber, and the body feeling is better.
