Description

Technical Field

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

[0002] A tapping massager is an electronic or manual tool designed to promote blood circulation, relieve muscle tension and pain, and relax the body by simulating manual tapping motions. These devices typically feature soft tapping heads or airbags that can apply gentle yet firm tapping motions to various body parts. The working principle of a tapping massager is based on the principles of traditional Chinese massage, using mechanical or pneumatic tapping to relax muscles and relieve fatigue. It has a wide range of applications, suitable for the neck, shoulders, back, waist, legs, and other body parts, helping to relieve stiffness and pain caused by maintaining the same posture for extended periods or overuse of muscles. Tapping massagers come in various types, including handheld, electric, and seated models. Handheld tapping massagers usually require manual operation, allowing users to adjust the tapping intensity and frequency according to their needs. Electric tapping massagers are driven by a motor and can automatically perform the tapping motions; users simply select the appropriate mode and intensity. The seat-type tapping massager is designed for use on seats. It uses the inflation and deflation of airbags to simulate tapping motions, providing a comfortable massage experience for users who sit for long periods of time.

[0003] Currently, in electric tapping massagers, the motor is connected to the tapping massage head via a linkage mechanism. One end of the linkage mechanism is fixed in place using a slot and adhesive, while the other end connects to the motor's output shaft. The motor then pushes and pulls the tapping massage head back and forth through the linkage mechanism. However, because the linkage mechanism needs to be fixedly connected to the tapping massage head, product assembly is cumbersome, hindering production capacity. Furthermore, the tapping massage head tends to produce significant noise when pulled backward, resulting in a poor user experience. Therefore, it is necessary to improve the current tapping massager. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a tapping mechanism for a massager, which can effectively solve the problems of complicated assembly and poor user experience of existing tapping massagers.

[0039] The flexible sleeve 20 covers the support shell 10, and the flexible sleeve 20 has a tapping massage head 21. In this embodiment, the flexible sleeve 20 is made of silicone or rubber, which is not limited to this, and the inner surface of the tapping massage head 21 is flat.

[0040] The guide sleeve 30 is fixed inside the support shell 10, and the guide sleeve 30 has a guide hole 31. In this embodiment, the guide sleeve 30 is located in the receiving cavity 101, and the guide sleeve 30 is fixed in the slot 102, which has a simple structure and stable installation. Furthermore, the guide sleeve 30 is disc-shaped and can be made of metal or plastic, without limitation.

[0041] The motor 40 is fixed inside the support housing 10. In this embodiment, the motor 40 is located in the accommodating cavity 101.

[0042] The eccentric rod 50 is fixed to the output shaft 41 of the motor 40 and is driven to rotate by the motor 40. In this embodiment, the eccentric rod 50 is located in the accommodating cavity 101. Specifically, the eccentric rod 50 includes a base 51 and a rod 52. The bottom surface of the base 51 has a shaft hole 501, in which the output shaft 41 of the motor 40 is inserted and fixed. The rod 52 extends integrally upward from the top surface of the base 51.

[0043] A bearing 91 is fixed on the swing seat 60, and the bearing 91 is sleeved on the eccentric rod 50. In this embodiment, the swing seat 60 is located in the accommodating cavity 101, and the bearing 91 is sleeved on the rod body 52. ​​Specifically, the swing seat 60 includes a main body 61 and a protrusion 62. The bottom surface of the main body 61 is recessed with a cavity 601, and the bearing 91 is fixedly embedded in the cavity 601. The bottom surface of the cavity 601 is provided with a through hole 602, which extends to the top surface of the main body 61. The rod body 52 passes upward through the through hole 602. The protrusion 62 extends outward from the edge of the main body 61, and a first connecting hole 603 is provided on the protrusion 62.

[0044] The rear end of the movable rod 70 is hinged to the edge of the swing seat 60, and the front end of the movable rod 70 extends forward through the guide hole 31, moving back and forth along the guide hole 31. In this embodiment, the movable rod 70 is located in the receiving cavity 101; the protrusion 62 is hinged to the rear end of the movable rod 70. Specifically, the rear end of the movable rod 70 has a clamp 71, which is U-shaped and clamps the protrusion 62.

[0046] The working principle of this embodiment is described in detail below:

[0047] In use, when the motor 40 is powered on, the motor 40 drives the eccentric rod 50 to rotate through the output shaft 41. The rotation of the eccentric rod 50 causes the swing seat 60 to swing left and right. Then, the swing seat 60 drives the movable rod 70 to move back and forth along the guide hole 31 of the guide sleeve 30. The abutment cap 80 moves back and forth with the movable rod 70. When the abutment cap 80 moves forward, it presses against the inner side of the tapping massage head 21, causing the tapping massage head 21 to extend forward and tap the body parts. When the abutment cap 80 moves backward, it no longer presses against the tapping massage head 21 and separates from it. The tapping massage head 21 returns to its original shape and resets under the elastic force of the flexible sleeve 20, thus causing the tapping massage head 21 to leave the body parts.

[0048] The key design feature of this invention is that by using a motor to drive an eccentric rod to rotate, the eccentric rod drives a swing seat to swing back and forth, which in turn drives a movable rod to move back and forth along the guide hole of the guide sleeve. The abutment cap acts on the tapping massage head as the movable rod moves back and forth. The overall structure is stable and the transmission is smooth. The abutment cap can be separated from the inner side of the tapping massage head without the need for fixed assembly, making product assembly simpler and improving production capacity. At the same time, the tapping massage head automatically returns to its original position by the elasticity of the flexible sleeve without the need for external force, resulting in less noise and a better silent effect, effectively improving the user experience.

[0049] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
