[0002] Air pressure adjustment is applied in many aspects in reality, and ball in life, instrument in experiment and tire in walking all need balanced air pressure adjustment, including negative pressure adjustment in a cup in cupping therapy of traditional Chinese medicine, which has not been completely solved until now. In the operation process of cupping therapy, due to cupping technology, sensitivity of patients and other problems, patients often feel that the comfort of the cup is not enough, or the negative pressure is not enough, or the negative pressure is too large. In the existing cup, only the negative pressure can be increased, and fine adjustment to reduce the negative pressure cannot be achieved. Therefore, in view of the problems in the process of cupping at present, repeated cupping operation is often performed, and therefore, there is still a lack of cup pressure regulator which is convenient and can fine adjust the negative pressure in the cup in positive and negative directions, so as to improve the comfort of patients.

[0014] The technical scheme provided by the embodiment of the application can have the following beneficial effects:

[0015] The present application is mainly designed to solve the problem that there is no device for adjusting the negative pressure in the container in positive and negative directions at present, and is especially suitable for adjusting the pressure in the gas tank. There is a technical gap in the existing devices. The present application is more convenient for clinical application and improves the comfort of the clinic and the health of the patient. During clinical operation, the patient's comfort is poor, and the negative pressure in the gas tank cannot be objectively adjusted, which brings inconvenience to repeated cupping operation. The present application can relatively objectively increase and decrease the negative pressure in the tank, promote the effect of clinical application, and is conducive to the development of modern Chinese acupuncture and massage. Therefore, the present application not only realizes the regulation and control of the positive and negative directions of the gas pressure in the gas tank, but also increases the experience of patient comfort, and is more convenient for clinical, scientific research and teaching of Chinese medicine clinical workers.
