Abstract
Description
Technical Field
[0001] This utility model relates to the field of massagers, and in particular to a coaxial bidirectional 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. The tapping and massage area is relatively small, resulting in unsatisfactory tapping and massage effects. Therefore, it is necessary to improve current tapping massagers. Utility Model Content
[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide a coaxial bidirectional tapping structure for a massager, which can effectively solve the problem that the tapping massage area of existing tapping massagers is relatively small.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A coaxial bidirectional tapping structure for a massager includes a housing, a flexible sleeve, a drive motor, two pull rods, and two eccentric rotating parts. The flexible sleeve is fitted outside the housing, and two tapping massage heads are located on the same side of the flexible sleeve, with the two tapping massage heads spaced apart along the axial direction of the flexible sleeve. The drive motor is located inside the housing and includes a main body and a rotating shaft. The rotating shaft is rotatably disposed inside the main body, with its two ends extending outward from the two ends of the main body. The two pull rods are axially reciprocating within the housing, with one end of each pull rod fixedly connected to the inner side of the two tapping massage heads. The two eccentric rotating parts are fixed to the two ends of the rotating shaft and rotated by the drive motor. The two eccentric rotating parts are connected to the other ends of the two pull rods and drive the two pull rods to reciprocate axially.
[0007] As a preferred embodiment, the inner sides of the two tapping massage heads are recessed with fixing grooves. The two pull rods include a base and a connector extending outward from the base. The connectors of the two pull rods 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.
[0010] As a preferred embodiment, the eccentric rotating component includes a turntable with a fixing hole recessed on one end face of the turntable. The end of the rotating shaft is inserted into the fixing hole for fixed connection. The eccentric column extends integrally from the edge of the other end face of the turntable. The structure is simple and easy to assemble.
[0011] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:
[0012] By setting two tapping massage heads on the same side of the flexible sleeve, and using a drive motor to drive two eccentric rotating parts to rotate, and then using the two eccentric rotating parts to drive two pull rods to move back and forth axially, the two tapping massage heads can be extended or retracted at the same time, thereby realizing simultaneous tapping massage on two different parts of the body. This effectively increases the area that can be tapped and massaged, greatly improves the tapping massage effect, and provides a better user experience.
[0013] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0027] 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 drive motor 30, two tie rods 40, and two eccentric rotating parts 50.
[0028] The housing 10 is made of hard plastic and is long and narrow. The housing 10 has a cavity 11 inside and two receiving holes 12 are provided on the same side of the housing 10. The two receiving holes 12 are arranged at intervals along the axial direction of the housing 10 and are both connected to the receiving cavity 11.
[0029] The flexible sleeve 20 is fitted over the housing 10. Two tapping massage heads 21 are located on the same side of the flexible sleeve 20 and are spaced apart along the axial direction of the flexible sleeve 20, with both heads facing the same direction. In this embodiment, the flexible sleeve 20 is made of silicone, but other soft rubber materials are also acceptable. A fixing groove 201 is recessed on the inner side of each of the two tapping massage heads 21, and the fixing groove 201 has a T-shaped cross-section. Furthermore, the two tapping massage heads 21 respectively cover and extend into the two receiving holes 12.
[0030] The drive motor 30 is disposed within the housing 10. The drive motor 30 includes a main body 31 and a rotating shaft 32. The rotating shaft 32 is rotatably disposed within the main body 31, and its two ends extend outward from the two ends of the main body 31, respectively. In this embodiment, the drive motor 30 is fixed in the accommodating cavity 11. The drive motor 30 can be a servo motor or a stepper motor, and is not limited thereto.
[0031] Both pull rods 40 are axially reciprocating within the housing 10, with one end of each rod fixedly connected to the inner side of the two tapping massage heads 21. In this embodiment, the two pull rods 40 are made of rigid materials such as plastic or metal. Specifically, each pull rod 40 includes a base 41 and a connector 32 extending from the base 41. The connectors 42 of the two pull rods 40 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 41 is annular, with a connecting hole 401 at its center. The connector 42 has a T-shaped cross-section to ensure a more stable and reliable connection between the pull rods 40 and the tapping massage heads 21.
[0032] The two eccentric rotating components 50 are respectively fixed at both ends of the rotating shaft 32 and driven to rotate by the drive motor 30. The two eccentric rotating components 50 are connected to the other ends of the two tie rods 40 and drive the two tie rods 40 to move back and forth axially. In this embodiment, the eccentric rotating component 50 has an eccentric column 51, which is inserted into the connecting hole 401 with clearance fit. Specifically, the eccentric rotating component 50 includes a turntable 52, one end face of which is recessed with a fixing hole 501. The end of the rotating shaft 32 is inserted into the fixing hole 501 for fixed connection. The eccentric column 51 extends integrally from the edge of the other end face of the turntable 52. The structure is simple and easy to assemble.
[0033] The working principle of this embodiment is described in detail below:
[0034] Place the body part to be massaged on the outside of the two tapping massage heads 21. When the drive motor 30 is powered on, the drive motor 30 drives the two eccentric rotating parts 50 to rotate simultaneously. Then, the rotation of the two eccentric rotating parts 50 drives the two pull rods 40 to move back and forth axially. Then, the axial back and forth movement of the two pull rods 40 drives the two tapping massage heads 21 to extend or retract simultaneously, thereby realizing simultaneous tapping massage of two different positions of the body part.
[0035] The key design feature of this invention is that by setting two tapping massage heads on the same side of the flexible sleeve, and using a drive motor to drive two eccentric rotating parts to rotate, and then using the two eccentric rotating parts to drive two pull rods to move back and forth axially, the two tapping massage heads can be extended or retracted at the same time, thereby realizing simultaneous tapping massage on two different parts of the body, effectively increasing the area that can be tapped and massaged, greatly improving the tapping massage effect, and providing a better user experience.
[0036] 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.
