Problems solved by technology
[0003] When the existing massager generates negative pressure, it needs to overcome a large frictional resistance to realize it, thus increasing the difficulty
At the same time, the massager usually makes a loud sound when massaging, which affects the user experience

The invention discloses a dynamic pressure generating device and a massager, the dynamic pressure generating device comprises an inner sleeve with a cavity, a moving part arranged in the cavity, and a driving mechanism for driving the moving part to linearly reciprocate, the inner sleeve is provided with an inner sleeve opening communicated with the cavity, and the inner sleeve is provided with an outer sleeve opening communicated with the cavity. A fit clearance is arranged between the inner sleeve and the moving part, and the fit clearance is not larger than 0.1 MM. During use, a driving mechanism enables a moving part such as a piston to reciprocate in the inner sleeve along the length direction of the inner sleeve, and when an opening of the outer sleeve is in a closed state, the reciprocating motion of the piston can change the volume of a cavity of the inner sleeve, so that the air pressure in the inner sleeve is dynamically changed. Due to the fact that the fit clearance is not larger than 0.1 MM, not only can pressure change be generated in the cavity when the moving part reciprocates, namely dynamic pressure be generated, but also negative pressure can be generated at the opening of the negative pressure inner sleeve, the negative pressure can be generated between the moving part and the cavity, and small resistance can also be generated between the moving part and the cavity. The device can be widely applied to massage products and the like.
Description
technical field [0001] The invention relates to the technical field of massage, in particular to a dynamic pressure generating device and a massager. Background technique [0002] With the increasing pace of life, people's work pressure is also increasing. In order to complete work tasks, people often work overtime. After a day of intense work, people's bodies become tired. In order to relieve fatigue and maintain physical and mental health, people generally use massagers to massage their bodies. Existing massagers are generally vibrating massagers. The motor drives the eccentric structure to rotate to generate vibrations. The massager contacts the massaged parts of the human body and transmits the vibrations to the human body, thereby achieving the effect of massaging the body. [0003] When existing massagers generate negative pressure, they need to overcome relatively large frictional resistance to realize it, thereby increasing the difficulty. At the same time, the mas...
