An energizing structure for a cold and hot massage head of a massage gun, including a fixed seat, a bushing, a conductive elastic piece, a slide bar, and a fixing base of a massage head. A connection portion protrudes from the fixing base of the massage head, and is embedded in the bushing. The fixed seat is fixedly disposed on the connection portion. A through-hole is provided at a bottom of the bushing. A limit groove is further provided at the bottom of the bushing, and is connected to the through-hole. A conductive wire protrudes from an edge of the fixed seat. The conductive elastic piece is bent, and has one side abutting against the conductive wire and an inner wall of the bushing and the other bent side passing through the through-hole and disposed in the limit groove. The bushing is fixedly disposed in the slide bar.

An electrically conductive structure of a massage head includes a body, a sheet-like conductive member, a conductive post, and a limiting member. A mounting groove is provided on the body, a plurality of limiting posts are disposed on a wall of the mounting groove, a first limiting groove matching the limiting post is provided at an edge of the sheet-like conductive member, a second limiting groove matching the conductive post is provided on the limiting member. When the limiting member is disposed inside the mounting groove, the conductive post is electrically connected to the sheet-like conductive member. Due to the combination of the sheet-like conductive member and the conductive post, a connection structure of a circuit is simplified. Therefore, a structure of a conventional circuit board that is easily damaged can be replaced. The electrically conductive structure has better anti-vibration performance and is not easily damaged because of vibration.

A device including footwear that is wearable on a foot provided with a processing unit, a power source, and a plurality of energy generator elements. The plurality of energy generator elements is independently operable and configured to convert electricity from the power source into a plurality of different energy types and configured to transmit the plurality of different energy types towards the foot. The plurality of energy generator elements includes a pressure generator element configured to output a pressure force to communicate with nerves associated with the foot and a heat generator element configured to convert the electricity from the power source into a heat flux recognizable by the foot.

A massage device includes a main body having a gripping section adapted to be held by a user, a massaging head, and an actuator configured to effect a reciprocating movement of the massaging head relative to the gripping section. The massaging head includes a negative pressure cavity connected to the suction pump and conveying negative pressure to an insert having a flexible part with contacting edge for contacting a body surface receiving therapeutic massage, and a rigid part for coupling the insert to the massaging head. Optionally, the flexible part collapses longitudinally in response to vacuum pressure and forms a more rigid reciprocal force transmission path from the massaging head to the contacting edge.

A percussion apparatus for sputum clearance includes a percussion unit, a drive unit, and a control unit, the percussion unit includes a percussion member and an angle detector, the angle detector is configured to detect an included angle between the reference plane and a horizontal plane, the control unit is electrically connected with the drive unit, and when the included angle conforms to a preset angle, the control unit controls the drive unit to drive the percussion unit to periodically percuss, which greatly saves the manpower and increase the efficiency of sputum clearance.

A spiral pull and insert structure of a massage head includes a massage head, a massage head cover, a plastic press member, and a sliding rod holder. The massage head cover is sleeved to the massage head. The massage head includes a rotating and inserting member. A rotating and inserting slide matching the rotating and inserting member is provided in the plastic press member, and an outer layer of the plastic press member is nested in and locked with the sliding rod holder. When the rotating and inserting member slides to a bottom of the rotating and inserting slide, the plastic press member is sleeved on the massage head cover. The spiral pull and insert structure of a massage head effectively resolves problems of screw stripped and jams in conventional designs using an innovative rotating and inserting method. In addition, processing is simplified, and processing costs are reduced.

The present disclosure relates to a spiral pull and insert structure of a massage head, including a massage head, a sliding rod holder, and a screw. A first groove is provided on the massage head. An end of the first groove includes a thread. A second groove is provided on the sliding rod holder. An end of the screw includes a thread. The sliding rod holder is sleeved on the massage head, and the screw is disposed inside the first groove and the second groove. A size of the screw matches a size of the first groove and a size of the second groove. Therefore, the massage head may be mounted and removed rapidly and conveniently, and stability and coaxality of the massage head are ensured during use.
