Description

Technical Field

[0001] This utility model relates to the field of massagers, and in particular to a coaxial reverse tapping structure for a massager. Background Technology

[0002] A tapping massager is a device designed to massage the body by simulating manual tapping. It is typically equipped with a motor and tapping heads that produce rhythmic tapping motions, stimulating muscles and acupoints. The working principle of a tapping massager is based on the motor's drive. When the motor is activated, it drives the tapping heads to produce rapid and rhythmic tapping movements. These tapping movements mimic the effect of manual tapping, stimulating muscles and acupoints, promoting blood circulation and muscle relaxation. The tapping motion of a tapping massager can accelerate blood circulation, thus helping to relieve muscle fatigue and stiffness. By stimulating muscles and acupoints, tapping massagers can help relieve various muscle aches, such as neck and shoulder pain, and lower back pain. Furthermore, using a tapping massager for a full-body massage can help relax the mind and body and improve sleep quality. In addition, moderate tapping massage can stimulate the lymphatic system, promote detoxification, and thus enhance immunity.

[0003] In existing technology, tapping massagers have only one tapping head, which is driven by a motor and can only tap and massage one area of ​​the body. If a different area needs to be massaged, the entire tapping massager needs to be moved, which is inconvenient to use. Therefore, it is necessary to improve the current tapping massagers.

The flexible sleeve is fitted outside the housing, and both sides of the flexible sleeve have tapping massage heads, which are coaxially arranged and facing opposite directions. The pull rod is axially reciprocating within the housing, and its two ends are fixedly connected to the inner sides of the two tapping massage heads. The drive motor is located inside the housing. The eccentric rotating component is fixed to the output shaft of the drive motor and is driven to rotate by the drive motor. The eccentric rotating component is connected to the pull rod and drives the pull rod to reciprocate axially.

[0007] As a preferred embodiment, the inner sides of both tapping massage heads are recessed with fixing grooves. The pull rod includes a base and connectors extending outwards in opposite directions on both sides of the base. The two connectors are respectively embedded in the fixing grooves of the two tapping massage heads for fixed connection, resulting in a simple structure.

[0008] As a preferred embodiment, the cross-section of both the fixing groove and the connector is T-shaped, so that the connection between the pull rod and the tapping massage head is more stable and reliable.

[0009] As a preferred embodiment, the base is annular, with a connecting hole at the center of the base. The eccentric rotating component has an eccentric column, which is inserted into the connecting hole with a clearance fit, making assembly easy.

[0026] Please refer to Figures 1 to 3 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a housing 10, a flexible sleeve 20, a tie rod 30, a drive motor 40, and an eccentric rotating component 50.

[0027] The housing 10 is made of rigid plastic. The housing 10 has a cavity 11 inside. The housing 10 has accommodating holes 12 on both sides. The two accommodating holes 12 are symmetrical to each other and are connected to the cavity 11.

[0028] The flexible sleeve 20 is fitted over the housing 10. Both sides of the flexible sleeve 20 have tapping massage heads 21, which are coaxially arranged and face opposite directions. In this embodiment, the flexible sleeve 20 is made of silicone, but other soft rubber materials are also acceptable. The inner side of each tapping massage head 21 is recessed with a fixing groove 201, the cross-section of which is T-shaped. Furthermore, the two tapping massage heads 21 respectively cover and extend into the two receiving holes 12.

[0029] The pull rod 30 is axially reciprocating within the housing 10, and its two ends are fixedly connected to the inner sides of the two tapping massage heads 21. In this embodiment, the pull rod 30 is made of a rigid material such as plastic or metal. Specifically, the pull rod 30 includes a base 31 and connectors 32 extending outwards from both sides of the base 31. The two connectors 32 are respectively embedded in the fixing grooves 201 of the two tapping massage heads 21 for fixed connection, resulting in a simple structure. Furthermore, the base 31 is annular, with a connecting hole 301 at its center. The connector 32 has a T-shaped cross-section to ensure a more stable and reliable connection between the pull rod 30 and the tapping massage heads 21.

[0030] The drive motor 40 is disposed inside the housing 10. In this embodiment, the drive motor 40 is fixed in the accommodating cavity 11. The drive motor 40 can be a servo motor or a stepper motor, and is not limited thereto.

[0031] The eccentric rotating component 50 is fixed to the output shaft 41 of the drive motor 40 and is driven to rotate by the drive motor 40. The eccentric rotating component 50 is connected to the tie rod 30 and drives the tie rod 30 to reciprocate axially. In this embodiment, the eccentric rotating component 50 has an eccentric column 51, which is inserted into the connecting hole 301 with a clearance fit. Specifically, the eccentric rotating component 50 includes a turntable 52, one end face of which is recessed with a fixing hole 501.
