[0018] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] A massage head structure of a massager, refer to Figures 1-3, including a bracket body 1 with upwardly inclined support brackets 103 at both ends; including a bearing 3, which includes an inner bearing ring and an outer bearing ring that can rotate relative to the inner bearing ring. The inner bearing ring is fixedly sleeved on the upper end of the support bracket 103. It includes a massage head 4, which has a cavity with an open bottom. The bottom end of the massage head 4 is fixedly sleeved outside the outer bearing ring. The massage head 4 can rotate left and right relative to the support bracket 103 through the bearing 3. The bearing 3 is assembled between the massage head 4 and the support bracket 103, and the bearing 3 is used to assist the massage head 4 in rotating, so that the massage head 4 operates with basically no noise and no jamming, thus solving the problems of overflowing glue, rotational jamming and assembly difficulties caused by ultrasonic welding. Moreover, the overall structure is simple, which is convenient for production and also reduces the production cost to a certain extent.

[0020] Among them, the end of the massage head 4 is an arc surface. The bearing 3 is preferably a plastic bearing, but no limitations are made here and it can also be of other shapes or materials.

[0021] Furthermore, a cavity 104 extending into the bracket body 1 is centrally penetrated through the support bracket 103. It also includes a heating element 2, which is arranged in the cavity 104 at the top of the support bracket 103. The heating end of the heating element 2 extends into the cavity of the massage head 4. The cavity 104 can be used to place the heating element 2 and some corresponding circuit traces of the heating element 2. A rubber ring or colloid can be added to the heating element 2, and it can be fixed in the cavity 104 by using the rubber ring or colloid to achieve the heating effect from the inside of the massage head 4, so as to play a role in hot compress. Since the bearing 3 itself has holes, it will not interfere with the use of the heating element 2.

[0022] Among them, the heating element 2 is preferably a rice bubble lamp, but no limitations are made here.

[0023] Furthermore, the bracket body 1, the support bracket 103 and the massage head 4 are integrally formed by an injection molding process respectively. Since the whole is integrally formed, it can ensure the overall shaping effect, ensure the consistency of the product, and at the same time the manufacturing process is simple and the production cost is lower.

[0024] Furthermore, a plurality of heat dissipation holes 401 are penetrated through the end face of the massage head 4. Through the heat dissipation holes 401, the heat inside the massage head 4 can be dissipated, avoiding overheating caused by heat accumulation during long-term use. Secondly, the dissipated heat can also play a role in assisting hot compress.

[0025] Among them, the heat dissipation holes 401 are at least three, but no limitations are made here.

[0026] Furthermore, a plurality of reinforcing rib positions 402 are circumferentially distributed on the inner wall of the massage head 4. Through the plurality of reinforcing rib positions 402, after the inside of the massage head 4 is hollowed out, the overall strength of the massage head 4 can still be ensured, avoiding deformation or damage of the massage head 4 during use.

[0027] Furthermore, both ends of the bracket main body 1 extend outward to form mounting portions, and through mounting holes 101 are provided on the mounting portions. The bracket main body 1 can be mounted at a reserved mounting position (not shown in the figure) of the massage mechanism core by screws through the mounting holes 101.

[0028] Furthermore, the outer end of the support frame 103 protrudes outward to form a limiting ring 102. The bottom end of the inner ring of the bearing abuts against the upper end surface of the limiting ring 102. The limiting ring 102 can assist in limiting the mounting position of part of the bearing 3 to ensure the mounting accuracy of the bearing 3.

[0029] It should be mentioned here that the above massage head structure design can be applied not only in the neck massager, but also in the massage head structures of other similar massagers, and will not be specifically elaborated here.

[0030] In summary, the bearing 3 is assembled between the massage head 4 and the bracket, and the bearing 3 is used to assist the massage head 4 in rotating, solving the problems of glue overflow, rotation jamming and assembly difficulty caused by ultrasonic welding. The structure is simple and the production cost is low. Moreover, the massage head 4 operates basically without noise and jamming, and the user experience is better, optimizing the product use experience.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
