Description

Technical Field

[0001] This utility model relates to the technical field of small kneading massagers, and specifically to a small kneading massager. Background Technology

[0002] The working principle of a small kneading massager is to use continuously moving massage heads to massage the body, thereby relaxing muscles, soothing nerves, promoting blood circulation, enhancing cell metabolism, and improving skin elasticity. It can also relieve fatigue, significantly reduce various chronic and acute pains and muscle soreness, relax the body, reduce stress, and decrease wrinkles. However, existing small kneading massagers on the market generally suffer from complex transmission structures and bulky sizes. Their transmission mechanisms often employ multi-stage gear sets or redundant linkage components, resulting in a large overall size and affecting portability. Furthermore, existing small kneading massagers have limited movement trajectories, only achieving simple rotation or vibration, making it difficult to simulate professional kneading techniques, thus limiting their usability and failing to meet the needs of current users.

[0021] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0022] For examples, see the appendix. Figures 1-3 A small kneading massager 1 includes a housing 20, a drive source 30, a transmission mechanism 40, and a massage head assembly 50. The drive source 30 is disposed on the outer wall of the housing 20, the transmission mechanism 40 is disposed inside the housing 20, and the drive source 30 is linked to the transmission mechanism 40. The massage head assembly 50 is disposed on the housing 20 and linked to the transmission mechanism 40. A positioning structure 60 is provided between the massage head assembly 50 and the transmission mechanism 40. The housing 20 is provided with a cover, and the cover is provided with multiple through holes. The through holes are used for the massage head assembly 50 to pass through, and the cover is used for the transmission mechanism 40 to close.

[0023] The housing 20 has a mounting cavity 200, which has a central hole 200a and multiple countersunk holes 200b. A bracket 200c is mounted on the central hole 200a, and the multiple countersunk holes 200b are arranged in a circular array beside the central hole 200a. The bracket 200c has a central positioning hole. The transmission mechanism 40 includes a worm gear 400, a main transmission gear 401, a secondary transmission gear 402, and multiple linkage gears 403. The worm gear 400 is mounted on the drive source 30, the secondary transmission gear 402 is mounted inside the bracket 200c, and the main transmission gear 401 is positioned between the worm gear 400 and the secondary transmission gear 402, with each main transmission gear 401 engaging with both the worm gear 400 and the secondary transmission gear 402. The transmission mechanism 40 is used to achieve synchronous driving action between the drive source 30 and the massage head 500, and saves the setting of linkage components. While ensuring transmission efficiency, the transmission mechanism 40 greatly reduces the overall size of the small kneading massager 1, making the small kneading massager 1 lighter and smaller, and improving the portability of subsequent small kneading massager 1 products. The multiple linkage gears 403 are respectively disposed in the countersunk hole 200b, and all of the multiple linkage gears 403 are meshed with the auxiliary transmission gear 402. The main transmission gear 401 includes a first gear plate 401a and a second gear plate 401b. The first gear plate 401a is meshed with the worm gear 400, and the second gear plate 401b is meshed with the auxiliary transmission gear 402.

[0024] The massage head assembly 50 includes two or more massage heads 500; the positioning structure 60 includes multiple positioning holes 600 and multiple positioning posts 601. The multiple positioning holes 600 are respectively disposed on the linkage gear 403, and the positioning posts 601 are disposed at the bottom of the massage head 500. The massage head 500 is fixed in the positioning hole 600 on the linkage gear 403 by the positioning posts 601. The positioning structure 60 facilitates installation while ensuring the stability of the massage action and improving the massage effect.

[0025] Each massage head 500 includes a bent rod 500a and a massage part 500b. The massage part 500b is disposed at the end of the bent rod 500a, and the massage part 500b preferably has a ball head structure. The bent rod 500a causes two or more massage parts 500b to form a cam trajectory when they move, thereby causing the massage parts 500b of the massage head 500 to move synchronously toward the center point or toward the outside to form a kneading action, thereby improving the massage efficiency and effect.

[0026] The housing 20 is provided with a drive source positioning groove 201, and the drive source positioning groove 201 is provided with a retaining plate; the drive source 30 is provided with a positioning retaining part, and the drive source 30 is fixed in the drive source positioning groove 201 by the positioning retaining part. The drive source 30 is preferably a motor. The positioning retaining part and the drive source positioning groove 201 are used to improve the convenience of installation.

[0027] The diameter of the first toothed disc 401a is larger than that of the second toothed disc 401b. The larger diameter of the first toothed disc 401a than that of the second toothed disc 401b is used to form a reduction gear structure, thereby improving the massage force of the massage head.

[0028] The main drive gear 401, the auxiliary drive gear 402, and the multiple linkage gears 403 are all provided with rotating rods. The rotating rods enable the main drive gear 401, the auxiliary drive gear 402, and the multiple linkage gears 403 to form a rotatable connection with the housing 20.

[0029] This invention significantly simplifies the traditional multi-axis transmission structure by employing a vertical meshing transmission design of a worm gear, main drive gear, and auxiliary drive gear, combined with multiple linked gears arranged in a ring array. The main drive gear adopts a double-tooth disc integrated structure, simultaneously realizing power transmission and deceleration functions, reducing the space occupied by independent deceleration modules, thereby reducing the overall size of the small kneading massager. This allows the small kneading massager to be used in smaller spaces, such as narrow joints, thus increasing its usability. Furthermore, the invention features a massage head with a curved rod, causing the massage head's massage portion to form a cam trajectory during movement. This allows the massage portion of the massage head to synchronously move towards the center or outwards to perform a kneading action, improving the massage function, efficiency, and effect.

[0030] This utility model is not limited to the above-described embodiments. Other small kneading massagers obtained by using the same or similar structures or devices as the above-described embodiments of this utility model are all within the protection scope of this utility model.
