Description

Rotary air positive and negative pressure massage device Technical Field The invention relates to the technical field of massage physiotherapy, in particular to a rotary air positive and negative pressure massage device. Background The massage is based on the theory of viscera and meridians of traditional Chinese medicine, and combines the anatomy and pathological diagnosis of Western medicine, but acts on specific parts of the body surface of human body by using the method to regulate the physiological and pathological conditions of the body, thus achieving the purpose of physiotherapy. The massage can be classified into health massage, sports massage and medical massage. With the development of the age and the technological progress, the existing massage modes are not limited to manual massage, and more massage instruments are used. For example, the prior massage chairs, foot massagers, neck massagers and the like do not perform targeted massage on affected parts according to the vasodilation rule of human blood vessels, but perform direct contact pressing in a mechanical way, so that the skin of the human body is greatly damaged, and the massage effect is not ideal. Therefore, some compressed air massagers for indirect massage through inspiration and blowing appear on the market, and the compressed air massagers are massage tools capable of generating negative pressure through a pressure field generating mechanism so as to generate adsorption feeling to adsorb and relax skin muscles to relieve fatigue and ache and further promote blood circulation, however, the conventional air positive and negative pressure massage devices usually adopt pistons to do linear reciprocating movement in cavities so as to generate negative pressure, the movement mode is more conventional, the adsorption effect of the generated negative pressure is poor, and therefore, the air positive and negative pressure massage device which can generate the movement mode of the negative pressure is needed to be provided.
