[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a multi-head massage movement for a massager, including: a machine housing 1, which is divided into upper and lower parts and is fixedly connected by screws.

[0023] A power device 3 is centrally arranged in the machine housing 1. In this embodiment, the power device 3 is composed of a bidirectional servo motor, and the two output ends of the bidirectional servo motor are designed as worms 31.

[0024] Inside the housing 1, a transmission gear set 4 is provided, and the transmission gear set 4 is divided into two symmetrically left and right parts.

[0025] The transmission gear set 4 includes a double gear 41, a front-end gear 42, a middle-end gear 43, a tail-end gear 44, and a transmission gear 45. There are two double gears 41 on one side, and they are meshed and connected on both sides of the worm 31. The double gear 41 is integrally stacked coaxially up and down by a worm gear and a gear. The worm gear is meshed and connected to the worm 31, and the gear is meshed and connected to the front-end gear 42 and the middle-end gear 43;

[0026] The tail-end gear 44 and the middle-end gear 43 are meshed and connected by the transmission gear 45;

[0027] The bidirectional servo motor drives the worm 31 to rotate, driving the double gear 41 to rotate. The double gear 41 drives the front-end gear 42 and the middle-end gear 43 to rotate. The middle-end gear 43 drives the tail-end gear 44 to rotate through the transmission gear 45.

[0028] On the housing 1, a massage head 2 is rotatably provided. The massage head 2 is divided into two symmetrically left and right columns, with three in each column, and they are coaxially connected to the front-end gear 42, the middle-end gear 43, and the tail-end gear 44 respectively. When the front-end gear 42, the middle-end gear 43, and the tail-end gear 44 rotate, they drive the massage head 2 thereon to rotate, and perform a rubbing massage on the human calf.

[0029] The massage head 2 includes a transmission rod 21. The transmission rod 21 is rotatably connected to the housing 1, and the transmission rod 21 is fixedly connected to the front-end gear 42 and the middle-end gear 43;

[0030] A one-way bearing 22 is provided between the tail-end gear 44 and the transmission rod 21. When the tail-end gear 44 rotates forward, it drives the massage head 2 to rotate through the one-way bearing 22. When the tail-end gear 44 rotates reversely, due to the effect of the one-way bearing 22, the transmission rod 21 remains stationary.

[0031] Working principle: The power device 3 and the transmission gear set 4 drive the massage head 2 to rotate, and perform a rubbing massage on the human body. Among them, a one-way bearing 22 is provided between the massage head 2 at the tail end and the transmission gear set 4, so that when rotating reversely, the massage head 2 at the tail end remains stationary.

[0032] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
