Description

Technical Field

[0001] This utility model relates to the field of massager technology, and in particular to a neck massager. Background Technology

[0002] A neck massager is a device that uses massage heads to simulate endurance massage techniques to massage the neck. It can relax neck muscles and prevent cervical spine diseases. Common massage mechanisms use the oscillating structure of the massage head to achieve a kneading massage effect.

[0003] Most current neck massagers do not have adjustable massage head spacing, making them unsuitable for people of different body types. For example, women's necks are thicker than men's, and neck thickness varies across different age groups. Existing neck massagers have a constant spacing between the two massage heads, which cannot be adjusted according to the user's neck thickness. When the user has a thinner neck, the massage effect will be poor; when the user has a thicker neck, the two massage heads will clamp the user's neck, resulting in poor comfort.

[0004] In view of this, the purpose of this utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content

[0029] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described below.

[0030] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0031] Reference Figures 1 to 6 This utility model discloses a neck massager, including a shell 1, a drive assembly 3 and a massage head mechanism 2. The drive assembly 3 is disposed inside the shell 1, and two sets of massage head mechanisms 2 are disposed on both sides of the drive assembly 3. The drive assembly 3 drives the massage head mechanisms 2 on both sides to swing, so that the massage head mechanisms 2 achieve the effect of kneading massage.

[0032] Reference Figures 2 to 5 Each massage head mechanism 2 includes a neck ball head assembly 21 and a shoulder ball head assembly 22. The neck ball head assemblies 21 on both sides swing relative to each other to form a clamping massage. The shoulder ball head assembly 22 cooperates with the neck ball head assembly 21 to clamp and knead. The drive assembly 3 is used to drive the neck ball head assembly 21 and the shoulder ball head assembly 22 to swing, so as to achieve the purpose of kneading and massaging the user's neck and shoulders.

[0033] The neck ball head assembly 21 includes a neck massage head 211 and a neck swing arm 212. The neck swing arm 212 is connected to the drive assembly 3. The neck massage head 211 is rotatably sleeved on the neck swing arm 212. By rotating the neck massage heads 211 on both sides, the distance between the two neck massage heads 211 can be adjusted.

[0034] Furthermore, the neck massage head 211 can be movably mounted on the neck swing arm 212. Specifically, the neck swing arm 212 is fitted with a slidable bushing 23. A limiting part 2111 is fixedly provided inside the neck massage head 211. The bushing 23 is slidably connected to the limiting part 2111. The limiting part 2111 is used to limit the vertical sliding distance of the bushing 23. A limiting block 231 is fixedly provided on the bushing 23. The limiting block 231 is located above the limiting part 2111. A limiting groove 2112 is provided on the limiting part 2111. The limiting block 231 is inserted into the limiting groove 2112 to limit the rotation of the neck massage head 211. In use, press the neck massage head 211 towards the neck swing arm 212 (i.e., press the neck massage head 211 downwards). At this time, the limiting block 231 disengages upwards from the limiting slot 2112, and the neck massage head 211 is in a rotatable state. The distance between the two neck massage heads 211 can be adjusted by rotating the neck massage head 211. The neck swing arm 212 is provided with a reset member that drives the neck massage head 211 to slide away from the neck swing arm 212 (i.e., upwards). When the neck massage head 211 is not pressed by an external force, the limiting block 231 is always engaged in the limiting slot 2112 under the action of the reset member, thus limiting the rotation of the neck massage head 211.

[0035] In some embodiments, the reset element is a reset spring 24, which is sleeved on the outer periphery of the bushing 23. One end of the reset spring 24 abuts against the limiting part 2111, and the other end abuts against the neck swing arm 212. When the neck massage head 211 is pressed down, the reset spring 24 is elastically compressed; when the force of pressing down on the neck massage head 211 is removed, the reset spring 24 is elastically released, and the neck massage head 211 slides upward on the neck swing arm 212 until the limiting block 231 is engaged in the limiting slot 2112, thereby achieving the limiting and fixing of the neck massage head 211 again.

[0036] In some embodiments, a limiting strip 2121 is fixedly provided on the neck swing arm 212, and a limiting groove 232 is formed in the bushing 23. When the bushing 23 slides up and down on the neck swing arm 212, the limiting strip 2121 slides in the limiting groove 232, and a limiting bolt 2122 is threadedly connected to the top of the neck swing arm 212. The limiting bolt 2122 is used to limit the sliding distance of the bushing 23 on the neck swing arm 212, so as to reduce the possibility of the bushing 23 disengaging from the neck swing arm 212 during the sliding process. The limiting strip 2121 and the limiting groove 232 cooperate to effectively reduce the possibility of relative rotation between the bushing 23 and the neck swing arm 212, so as to ensure the reliability of the rotation adjustment of the neck massage head 211.

[0037] Reference Figure 3 and Figure 4In some embodiments, the neck massage head 211 has an "8" shaped structure, with one end of the "8" shaped structure being larger than the other end. When the neck massage head 211 is pressed and rotated 180°, the orientation of the larger end and the smaller end can be switched. By rotating the neck massage head 211 to match its shape, the distance between the two neck massage heads 211 and the distance between the neck massage head 211 and the shoulder massage head 221 can be adjusted. Specifically, when the larger end of the neck massage ball heads on both sides faces the shoulder massage head 221, the distance between the neck massage head 211 and the shoulder massage head 221 will be relatively small. Also, since the larger end of the neck massage head 211 is facing the shoulder massage head 221, the distance between the neck massage heads 211 on that side will also be relatively small, which can accommodate users with smaller body sizes. When the smaller end of the neck massage head 211 on both sides is facing the shoulder massage head 221, the distance between the neck massage head 211 and the shoulder massage head 221 will be relatively large, which can accommodate users with larger body sizes.

[0038] Reference Figure 2 and Figure 5 The shoulder ball head assembly 22 includes a shoulder massage head 221 and a shoulder swing arm 222. The shoulder swing arm 222 is connected to the drive assembly 3. The shoulder massage head 221 is rotatably connected to the shoulder swing arm 222. The shoulder massage head 221 is made of soft rubber and is inserted into the shoulder swing arm 222. Users can directly rotate the shoulder massage heads 221 on both sides to adjust the intensity of the kneading sensation.

[0039] Reference Figure 6 The drive assembly 3 includes a drive housing 31, a drive motor 32, a drive gear 33, and a main shaft 34, all of which are housed within the drive housing 31. The drive gear 33 is mounted on the main shaft 34, and the drive motor 32 drives the drive gear 33 to rotate, thereby causing the main shaft 34 to rotate. Two massage head mechanisms 2 are respectively located at both ends of the main shaft 34. Therefore, the rotation of the main shaft 34 and the internal engagement of the massage head mechanisms 2 cause the neck massage head 211 and the shoulder massage head 221 to oscillate.

[0040] A swing arm inclined seat 341 is sleeved on the main shaft 34. The neck swing arm 212 is rotatably sleeved on the swing arm inclined seat 341. The neck swing arm 212 is connected to the main shaft 34 through the swing arm inclined seat 341. When the main shaft 34 rotates, the swing arm inclined seat 341 rotates with the main shaft 34, but the neck swing arm 212 does not rotate with the swing arm inclined seat 341, but swings according to the inclination of the swing arm inclined seat 341. A fixed shaft 2123 is provided at the bottom of the neck swing arm 212. A swing groove 12 is provided inside the outer shell 1, and the swing groove 12 is located below the fixed shaft 2123. The swing groove 12 is arranged in one direction, and the fixed shaft 2123 is set in the swing groove 12. That is, the fixed shaft 2123 can only swing within the range of the swing groove 12. Therefore, the neck massage head 211 swings back and forth with the cooperation of the swing arm inclined seat 341 and the swing groove 12.

[0041] A sloping cam 342 is fitted onto the main shaft 34. A shoulder arm 222 is rotatably mounted on the sloping cam 342. The shoulder arm 222 is connected to the main shaft 34 via the sloping cam 342. When the main shaft 34 rotates, the sloping cam 342 rotates with it, but the shoulder arm 222 does not rotate with the sloping cam 342; instead, it oscillates along the sloping surface of the cam 342. A groove 2221 is provided on the shoulder arm 222, and a limiting shaft 313 is provided on the drive housing 31, located within the groove 2221. The limiting shaft 313 and the groove 2221 work together to restrict the oscillation trajectory of the shoulder arm 222. Through the cooperation of the cam structure and the restriction of the limiting shaft 313 and the groove 2221, under the drive of the drive assembly 3, the shoulder massage head 221 can oscillate back and forth in both the forward and backward and left and right directions, achieving the purpose of kneading the user's shoulders.

[0042] Specifically, a limiting groove 2221 is provided on the shoulder arm 222 for limiting, and the limiting shaft 313 is fixedly installed on the drive housing 31. The shoulder arm 222 rotates eccentrically on the inclined cam 342 through a cam structure. Due to the setting of the limiting shaft 313 and the groove 2221, the shoulder arm 222 swings back and forth under the push of the inclined cam 342 structure. Furthermore, the inclined structure on the inclined cam 342, due to the adjustment of the inclined angle during rotation, causes the shoulder arm 222 on the inclined surface to swing left and right, thereby realizing the back-and-forth swing of the shoulder massage head 221 in both the back-and-forth and left-and-right directions.

[0043] In this embodiment, a cam fixing plate 343 is provided on one side of the inclined surface of the inclined cam 342. The cam fixing plate 343 is locked to the inclined cam 342, and the cam fixing plate 343 fixes the inclined cam 342 and the shoulder swing arm 222 onto the inclined cam 342 to reduce the possibility of the shoulder swing arm 222 slipping off the inclined cam 342. A swing arm fixing plate 344 is provided on one side of the inclined surface of the swing arm inclined seat 341. The swing arm fixing plate 344 is locked to the swing arm inclined seat 341, so that the neck swing arm 212 is fixedly fitted onto the swing arm inclined seat 341 to reduce the possibility of the neck swing arm 212 slipping off the swing arm inclined seat 341.

[0044] The drive housing 31 includes an upper drive housing 311 and a lower drive housing 312, which are spliced ​​and fastened together to form the entire drive housing 31. A main shaft 34 is rotatably mounted on the lower drive housing 312, and both ends of the main shaft 34 extend out of the lower drive housing 312 and connect to the massage head mechanism 2. A drive motor 32 is located outside the lower drive housing 312, and the output shaft of the drive motor 32 passes through the lower drive housing 312 and connects to the internal structure of the drive housing 31. Specifically, a drive worm gear 321 is fixedly connected to the output shaft of the drive motor 32, and a through hole is provided on the lower drive housing 312, through which the drive worm gear 321 extends into the lower drive housing 312. The drive motor 32 is also connected to a double gear 35, which is rotatably mounted inside the lower drive housing 312. The double gear 35 has an internal gear 351 and an external gear 352. The external gear 352 meshes with the helical part of the drive worm 321, and the internal gear 351 meshes with the driving gear 33 on the main shaft 34. The drive motor 32 drives the drive worm 321 to rotate, and the double gear 35 follows the rotation of the drive worm 321, which in turn drives the driving gear 33 to rotate. The main shaft 34 then follows the rotation of the driving gear 33, ultimately realizing the oscillation of the massage head mechanisms 2 on both sides. In addition, to facilitate the rotation of the main shaft 34 on the lower drive housing 312, a bearing 345 can be installed on the main shaft 34. By setting the bearing 345, the rotation between the main shaft 34 and the lower drive housing 312 can be made smoother.

[0045] Furthermore, the outer casing 1 includes an upper outer casing 1 and a lower outer casing 1. The drive assembly 3 is installed inside the lower outer casing 1, while the neck ball head assembly 21 and the shoulder massage head 221 assembly are exposed outside the upper casing, allowing the neck massage head 211 and the shoulder massage head 221 to perform kneading massage. Specifically, the upper casing has a clearance hole 11, through which the neck swing arm 212 and the shoulder swing arm 222 extend to the outside of the outer casing 1. The two sets of massage head mechanisms 2 are mirror images of each other on the drive assembly 3, with the neck swing arm 212 positioned near the end of the main shaft 34 and the shoulder swing arm 222 positioned near the drive motor 32 on the main shaft 34. That is, the two sets of neck ball head assemblies 21 are positioned on both sides of the two sets of shoulder ball head assemblies 22, and the shoulder ball head assemblies 22 are positioned lower than the neck ball head assemblies 21 for easy kneading.

[0046] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model.
