Massager

A massager, comprising:

• a housing;
• a piston, at least partially located in the housing and defining an accommodating hole;
• a driving mechanism, connected to the piston and configured to cause the piston to reciprocate;
• and
• a connecting module, comprising a connecting member and a massaging head connected to the connecting member, wherein the connecting member is arranged to be inserted into the accommodating hole, and the connecting member is configured to restrain the massaging head from separating from the piston while the piston reciprocates at a speed higher than a predetermined speed;
• wherein the connecting member is arranged with an annular elastic member and a screwing portion;
• the annular elastic member and the screwing portion sleeve a periphery of the connecting member;
• an end of the annular elastic member is arranged to be connected to the massaging head;
• a second end of the annular elastic member disposed away from the massaging head is arranged to be connected to an end of the screwing portion;
• and the screwing portion is arranged to extend away from the annular elastic member and away from the massaging head;
• the annular elastic member is arranged to be in damping connection with an accommodating hole wall of the piston;
• the screwing portion is screwedly connected to the accommodating hole wall of the piston;
• wherein the piston is arranged with a second connecting member matched with the annular elastic member and the screwing portion arranged on the connecting member;
• wherein the massager further comprises a sensing module and a massager body, the massager body is arranged at an exterior of the connecting member, the sensing module comprises a magnetic member and a magnetic sensor, the magnetic member is located at an end portion of the connecting member inserted into the accommodating hole, and the magnetic sensor is located on a side wall of the massager body or a side wall of the piston;
• and the magnetic member is eccentrically arranged relative to an axis of the connecting member;
• and
• the magnetic sensor is configured to detect a relative position between the connecting member and the accommodating hole;
• the driving mechanism is configured to be activated to drive the piston to reciprocate only when the connecting member is tightened with the accommodating hole;
• and when the magnetic sensor detects a displacement between the connecting member and the accommodating hole during operation of the driving mechanism, the driving mechanism is configured to be immediately controlled to stop operating.
