[0002] Massagers are used to pat and knead the body parts of users. In some patting massagers, the patting function is generally realized by a motor, a push rod, and a patting member provided on the push rod. Specifically, the motor is used to drive the push rod to reciprocate at a high frequency to simulate patting and hammering.

[0003] However, in such massagers, limited by the structural strength of the transmission structure between the motor and the push rod, the reciprocating movement speed of the push rod is low and the force is weak. As a result, the patting force and frequency of the patting member on the body part are weak, and the experience is not strong. Summary of the Invention

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0032] In the description of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0033] Please refer to Figures 1 to 4 together, and now the massager provided by the embodiments of the present application will be described.

[0034] The massager described in the embodiments of the present application includes a seat body 100, a motor 200, a worm 300, a worm gear 400, an eccentric swing member 500 and a push rod 600.

[0035] Specifically, referring to Figures 1 to 3 , the motor 200 is disposed on the seat body 100, and the worm 300 is connected to the output shaft of the motor 200; the worm gear 400 is rotatably disposed on the seat body 100 and meshes with the worm 300.

[0036] The eccentric swing member 500 includes a connecting portion 510 and a driving portion 520, and the driving portion 520 is eccentrically arranged on the connecting portion 510. Further, the connecting portion 510 is directly or indirectly connected to the worm gear 400. For example, the connecting portion 510 can be directly coaxially and fixedly connected to the worm gear 400, or there can also be a transmission gear set connected between the connecting portion 510 and the worm gear 400, such as a speed increasing gear set or a speed reducing gear set, and the connecting portion 510 is fixedly connected to the gear set. When the worm 300 rotates, the worm gear 400 directly or indirectly drives the connecting portion 510 to rotate, so that the driving portion 520 can rotate around the connecting portion 510.

[0037] The push rod 600 is slidably arranged on the seat body 100 in the first direction. At one end of the push rod 600, a chute 610 for accommodating the driving portion 520 is arranged in the second direction. The driving portion 520 can reciprocally slide relative to the chute 610 in the chute 610 in the second direction, and the first direction and the second direction are perpendicular to each other. Specifically, since the push rod 600 can only slide in the first direction, the driving portion 520 can only rotate around the axis where the connecting portion 510 is located under the drive of the connecting portion 510. Thus, when the driving portion 520 rotates, it slides in the second direction relative to the chute 610, thereby driving the push rod 600 to reciprocally move in the first direction.

[0038] A connecting seat 700 is arranged at one end of the push rod 600 far from the chute 610. Optionally, the connecting seat 700 is detachably arranged, and the connecting seat 700 is used for assembling a massage head (not shown in the figure). In this way, the user can choose to replace and install a suitable massage head according to their own massage needs.

[0039] By arranging the massager in this way, the push rod 600 is pushed by the worm 300 and the worm gear 400 to reciprocally move. The driving force of the worm 300 and the worm gear 400 is large, and the arrangement of the chute 610 enables the push rod 600 to better bear the inertia generated by the high-frequency reciprocating movement of the eccentric swing member 500, so that the push rod 600 can continuously and stably reciprocally move, and can achieve a larger hammering force, thereby enhancing the user's massage experience.

[0040] Reference Figures 2 to 3 , in some embodiments, the aforementioned eccentric swing member 500 is directly fixedly connected to the worm gear 400. In this way, since the worm gear 400 drives the push rod 600 to reciprocally move once per revolution, the rotation speed of the motor 200 shaft only undergoes a single-stage transmission of the worm 300 and the worm gear 400. Therefore, the reciprocating frequency of the push rod 600 is higher, so that the massage head can achieve a higher frequency of hammering to enhance the user's massage experience.

[0041] Reference Figure 3, on the basis of any of the foregoing embodiments, a bearing 530 is sleeved on the outer side of the driving portion 520 of the eccentric swing member 500, and the outer circumferential surface of the bearing 530 is in rolling contact with the inner groove wall of the chute 610 on the push rod 600. In this way, when the eccentric swing member 500 drives the push rod 600 to reciprocate, the friction between the driving portion 520 and the chute 610 is extremely small, which is beneficial to improving the smoothness of the reciprocating movement of the push rod 600, thereby improving the massage experience.

[0042] Reference Figures 1 to 3 , on the basis of any of the foregoing embodiments, in some embodiments, the axis of the motor 200 is arranged parallel to the first direction. Preferably, the motor 200 is arranged in parallel on one side of the push rod 600. Since the length of the push rod 600 is relatively long, that is, the space occupied by the push rod 600 on the seat body 100 in the first direction is relatively large. By arranging the motor 200 in this way, the space of the seat body 100 in the first direction is better utilized, so as to compress the space occupied in the second direction, thereby making the width or thickness of the seat body 100 smaller, thus facilitating the user to hold.

[0043] On the basis of any of the foregoing embodiments, in some embodiments, a plug-in position is provided on the connecting seat 700, and PIN pins are provided at the bottom of the plug-in position. The plug-in position is used for plugging in the massage head. By providing PIN pins in the plug-in position, the massage head assembled in the plug-in position can be configured with electronic components, such as electrotherapy components, etc., so as to enrich the massage experience of the user.

[0044] Reference Figures 2 to 3 , on the basis of any of the foregoing embodiments, the connecting seat 700 and the push rod 600 are detachably connected by bolts. In this way, the disassembly between the connecting seat 700 and the push rod 600 is simple, convenient and fast.

[0045] Reference Figures 2 to 4 , on the basis of any of the foregoing embodiments, a sliding hole 100b and a movable hole 100a are formed in the seat body 100 along the first direction; wherein, the sliding hole 100b is used for passing through the push rod 600, and the movable hole 100a is used for arranging the connecting seat 700. Specifically, the movable hole 100a communicates with one end surface of the seat body 100 so that the connecting seat 700 can be put into the movable hole 100a from one end of the seat body 100; the sliding hole 100b penetrates through the movable hole 100a and the other end surface of the seat body 100, so that both ends of the push rod 600 slidably arranged in the sliding hole 100b can be respectively connected to the eccentric swing member 500 and the connecting seat 700.

[0046] Further, reference Figures 2 to 4, in some embodiments, the base body 100 includes a first component 110 and a second component 120 that are covered and detachably connected to each other, and the covering plane of the first component 110 and the second component 120 is parallel to the plane where the first direction and the second direction are located. Specifically, the moving hole 100a and the sliding hole 100b are provided on the first component 110, and a space for accommodating the turbine and the worm 300 is formed by enclosing between the first component 110 and the second component 120; at the same time, a through hole 111 for inserting the eccentric swing member 500 is also provided on the first component 110, and the connecting portion 510 on the eccentric swing member 500 can pass through the aforementioned through hole 111 and be fixedly connected to the worm gear 400. By setting the base body 100 in this way, when the massager is assembled, the turbine 400 and worm 300 structure can be assembled on the second component 120 first, and while the first component 110 and the second component 120 are covered, the eccentric swing member 500 is inserted through the through hole and connected to the worm gear 400, which is convenient for assembly.

[0047] Further, referring to Figure 4 , in some embodiments, an avoidance space A is formed on the first component 110 between the outside of the sliding hole 100b and the outside of the bottom of the moving hole 100a. When the first component 110 and the second component 120 are covered and connected, an installation space for accommodating the motor 200 is formed by enclosing between the avoidance space A and the outer wall of the second component 120. In this way, on the one hand, the motor 200 does not need to be arranged inside the space formed by enclosing the first component 110 and the second part. After the turbine 400, the worm 300 and the eccentric swing member 500 are assembled on the base body 100, the motor 200 can be connected to the outside of the first component 110 to complete the preliminary assembly of the massager, and the assembly is simple and fast; on the other hand, by arranging the motor 200 in the avoidance space A, the space in the first direction on the base body 100 can be utilized as much as possible to reduce the volume of the base body 100, which is beneficial to the miniaturization of the volume of the massager.

[0048] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
