In summary, the pressure regulating mechanism provided in this embodiment moves along the tank body 3 to be regulated through the pressure regulating member 1, so as to regulate the pressure between the sealing surface and the tank body 3 to be regulated, thereby meeting the actual requirement; the pressure regulating piece 1 moves in the tank body 3 to be regulated through the connecting piece 2, so that the damage caused by long-term movement of the pressure regulating piece 1 is avoided, meanwhile, the air leakage and pressure relief of a gap between the pressure regulating piece 1 and the tank body 3 to be regulated are avoided, and the sealing effect of the tank body 3 to be regulated is further improved; the sealing ring 4 arranged between the pressure regulating part 1 and the connecting part 2 is used for regulating the gap between the pressure regulating part 1 and the connecting part 2 for sealing, so that the sealing effect in the tank body 3 to be regulated is better ensured, the pressure in the tank body 3 to be regulated is prevented from leaking, and the cupping effect is ensured; seal ring 4 is compressed through first seal structure 5 to prevent that there is the clearance in pressure regulating spare 1 and connecting piece 2, and then further ensure the sealed effect of waiting to transfer jar body 3, prevent to wait to transfer the pressure in the jar body 3 and reveal, thereby guarantee the effect of cupping therapy once more.
Preferably, the connecting piece that provides in this embodiment is the annular plate, and the outer wall of annular plate seals so that seal the clearance between the two through sealing ring 6 with the inner wall contact department of waiting to transfer jar body 3, and then further ensures the sealed effect of waiting to transfer jar body 3, prevents to wait to transfer the pressure in the jar body 3 and reveals to guarantee the effect of cupping therapy.
Further, the connecting piece provided in the embodiment compresses the sealing ring 6 through the second sealing structure 221 arranged in the groove 22, so as to prevent a gap from being formed between the outer wall of the connecting piece 2 and the inner wall of the tank body 3 to be adjusted, further avoid air leakage between the tank body 3 to be adjusted and the sealing surface, prevent pressure leakage in the tank body 3 to be adjusted, and further ensure the cupping effect again.
Negative pressure tank example:
this embodiment has still provided a negative pressure jar, is provided with above-mentioned pressure regulating mechanism on this negative pressure jar. The specific implementation process of the pressure regulating mechanism may be as described above, and this embodiment is not described herein again.
Due to the fact that the pressure regulating mechanism has the effect, the negative pressure tank with the pressure regulating mechanism also has the corresponding technical effect.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
