In addition, the massage head can roll, the friction force is small, and the friction loss on the surface of the massage head is small, which can increase the service life.

[0041] Specifically, the eccentric wheel assembly 8 is composed of a first eccentric wheel 801, a second eccentric wheel 802, and an eccentric wheel pressure cover 803 connected by screws. The first eccentric wheel 801 includes an eccentric boss portion 8011. The axis of the eccentric boss portion 8011 does not coincide with the axis of the kneading shaft 10. A first flange portion 8012 is provided on one side of the eccentric boss portion 8011. The trapezius muscle massage arm 4 is sleeved on the eccentric boss portion 8011 and is sandwiched between the first flange portion 8012 and the second flange portion 8021.

[0042] The second eccentric wheel 802 includes a second flange 8021 and a deflection wheel 8022. The deflection wheel 8022 is disposed on a side of the second flange 8021 away from the eccentric cam. The side of the second flange 8021 away from the eccentric cam includes an abutment surface for contacting the massage arm. This abutment surface is inclined relative to the rotation center of the eccentric wheel assembly 8, that is, it is inclined relative to the axis of the kneading shaft 10, such that the axis of the deflection wheel 8022 is inclined relative to the rotation center of the eccentric wheel assembly 8. The shoulder and neck massage arm 1 is sleeved on the outer wall of the deflection wheel 8022. After the deflection wheel 8022 cover is secured to the deflection wheel 8022, the shoulder and neck massage arm 1 is sandwiched between the deflection wheel 8022 cover and the second flange 8021. When the kneading shaft 10 rotates, the trapezius massage arm 4 reciprocates vertically, and the massage end of the shoulder and neck massage arm 1 reciprocates along the axis of the kneading shaft 10.

[0043] The detachable eccentric wheel group 8 can simplify the mold on the one hand, and on the other hand, it can facilitate and independently control the roundness and dimensional accuracy of the matching cylindrical surfaces of the first eccentric wheel 801 and the second eccentric wheel 802. The better the roundness, the higher the accuracy and the more precise the matching between the shoulder and neck massage arm and the trapezius massage arm 4, the less likely it is to have large gaps and shaking, thereby causing abnormal noise.

[0044] Specifically, a first positioning post 8013 is provided on the side of the eccentric cam portion, a first positioning groove 8023 is provided on the side of the second eccentric wheel 802 facing the eccentric cam portion, and the first positioning post 8013 is inserted into the first positioning groove 8023. A second positioning post 8024 is provided on the side of the deflection wheel 8022, and a second positioning groove 8031 ​​is provided on the side of the deflection wheel 8022 cover, and the second positioning post 8024 is inserted into the second positioning groove 8031. By aligning the positioning posts and positioning grooves for positioning and assembling, and then tightening with screws, the assembly accuracy of the eccentric wheel assembly can be improved, and the problem of disengagement can be avoided.

[0045] For example 2, please refer to Figures 1 to 13The present invention provides a massage movement structure 200, including the massage component 100 in Example 1, the massage movement also includes a shell 9, a kneading shaft 10, a knocking shaft 11, a motor 12 and a transmission mechanism 13, the motor 12 and the transmission mechanism 13 are arranged inside the shell 9, the motor 12 drives the kneading shaft 10 and the knocking shaft 11 to rotate through the transmission mechanism 13, the kneading shaft 10 and the knocking shaft 11 are rotatably connected to the shell 9, and the end of the kneading shaft 10 extends to the outside of the shell 9 and is connected to the eccentric wheel group 8, the end of the knocking shaft 11 extending to the shell 9 is connected with a hinge seat 14, the hinge seat 14 is eccentrically installed at the end of the knocking shaft 11, the hinge seat 14 is hinged with an articulated arm 15, and the lower end of the trapezius massage arm 4 is provided with an assembly ring 403, the assembly ring 403 is provided with a receiving groove, and the end ball of the articulated arm 15 is hinged in the receiving groove. When the knocking shaft 11 rotates, it drives the hinge seat 14 and the hinge arm 15 to move, so that the trapezius massage arm 4 produces a knocking massage effect.

[0046] Specifically, the transmission mechanism 13 includes a belt transmission assembly 131, a gear transmission assembly 132, a transmission shaft 133 and a worm gear transmission assembly 134, the belt transmission assembly 131 includes a driving pulley 1311, a driven pulley 1312 and a transmission belt 1313, the driving pulley 1311 is connected to the end of the output shaft of the motor 12, the driven pulley 1312 is rotatably connected to the knocking shaft 11, and the transmission belt 1313 is wound around the outer walls of the driving pulley 1311 and the driven pulley 1312; a connecting bearing 22 is connected to the outside of the knocking shaft, and the connecting bearing is connected between the driven pulley and the knocking shaft for supporting the driven pulley.

[0047] The gear transmission assembly 132 includes a driving bevel gear 1321 and a driven bevel gear 1322 meshing with the driving bevel gear 1321. The driving bevel gear 1321 is rotatably connected to the knock shaft 11. A composite bushing 21 is further connected to the outside of the knock shaft 11. The composite bushing 21 is connected between the driving bevel gear and the knock shaft for supporting the driving bevel gear. The side wall of the driven pulley 1312 is provided with a first power transmission member 16, and the side wall of the driving bevel gear 1321 is provided with a second power transmission member 17. The first power transmission member 1 6 is fixedly connected to the second power transmission member 17, the outer wall of the knocking shaft 11 is connected to the one-way bearing 18, the outer wall of the one-way bearing 18 is connected to the first power transmission member 16, the transmission shaft 133 is rotatably connected in the housing 9, the driven bevel gear 1322 is connected to one end of the transmission shaft 133, the worm gear transmission assembly 134 includes a worm wheel 1341 and a worm 1342 meshing with the worm wheel 1341, the worm wheel 1341 is fixedly connected to the outer wall of the kneading shaft 10, and the worm 1342 is fixedly connected to the other end of the transmission shaft 133.

[0048] The one-way bearing 18 is capable of transmitting force and torque in one direction while being free to rotate in the opposite direction.

[0049] If the user desires both kneading and tapping massage, they can control the motor 12 by rotating it in the forward direction (i.e., in a direction that allows the one-way bearing 18 to transmit force and torque). This power is then transmitted via the drive belt 1313 to the driven pulley 1312 and the driving bevel gear 1321. Since the drive motor 12 rotates in a direction that allows the one-way bearing 18 to transmit force and torque, when the driven pulley 1312 or the driving bevel gear 1321 rotates, the tapping shaft 11 rotates along with them, and through the articulated seat 14 and articulated arm 15, the massage arm produces a tapping massage effect. Simultaneously, the driving bevel gear 1321 also rotates the driven bevel gear 1322, which in turn rotates the kneading shaft 10 via the drive shaft 133 and worm gear assembly 134, driving the kneading massage assembly to perform a massage action, thereby achieving simultaneous kneading and tapping massage.

[0050] When the motor 12 rotates in the reverse direction, the one-way bearing 18 idles on the outer wall of the knocking transmission shaft 133, and the knocking shaft 11 stops rotating. The power of the motor 12 is transmitted to the driven pulley 1312 and the driving bevel gear 1321 via the transmission belt 1313 (the driven pulley 1312 also idles on the outer wall of the knocking shaft 11 at this time). The driving bevel gear 1321 drives the driven bevel gear 1322 to rotate, and the kneading shaft 10 rotates via the transmission shaft 133 and the worm gear transmission assembly 134, thereby driving the kneading massage assembly to perform a massage action, thereby achieving kneading massage.

[0051] After the speed output by motor 12 is decelerated by belt drive assembly 131 and further decelerated by gear drive assembly 132, the speed of worm 1342 is significantly slower than in the prior art. The slower the speed of worm 1342, the quieter the meshing sound between worm 1342 and worm wheel 1341, the smoother the transmission, and the lower the precision requirements for worm wheel 1341 and worm 1342. The output shaft of motor 12 only needs to drive the driving pulley 1311 to rotate, so the output shaft of motor 12 can be set relatively short, less prone to bending and deformation, and easy to process while ensuring precision and strength.

[0052] Specifically, the second power transmission member 17 has a connecting groove 171 that matches the first power transmission member 16. The first power transmission member 16 is connected to the connecting groove 171. The outer wall of the first power transmission member 16 is provided with a transmission protrusion 161, which extends in the axial direction of the first power transmission member 16. The inner wall of the connecting groove 171 is provided with a groove 172 that matches the transmission protrusion 161. When the second power transmission member 17 is connected to the first power transmission member 16, the transmission protrusion 161 is inserted into the groove 172. The transmission protrusion 161 and the groove 172 cooperate with each other, so that when the driven pulley 1312 rotates, the driving bevel gear 1321 rotates accordingly, thereby transmitting power to the gear transmission assembly 132 and the worm gear transmission assembly 134.

[0053] Specifically, a shaft end fixing sleeve 19 is further included. The output shaft of the motor 12 is rotatably connected to the shaft end fixing sleeve 19 , and the shaft end fixing sleeve 19 is fixed inside the housing 9 .

[0054] The inner wall of the shaft end fixing sleeve 19 is provided with several oil reservoirs. These reservoirs store lubricating grease, reducing wear on the shaft end fixing sleeve 19 and thus increasing its service life. Alternatively, a third bearing (not shown) is provided on the inner wall of the shaft end fixing sleeve 19. The outer ring of the third bearing mates with the inner wall of the shaft end fixing sleeve 19, and the output shaft of the motor 12 is connected to the inner ring of the third bearing. The shaft end fixing sleeve 19 prevents the motor 12 from tilting due to the tension of the transmission belt 1313.

[0055] For example three, please refer to Figures 1 to 13 The present invention provides a massager 300, comprising the massage mechanism structure 200 of the second embodiment. The massager 300 further comprises a bottom shell connected to the bottom of the housing 9. Two sets of guide components are disposed within the bottom shell. Each set of guide components comprises two guide blades 20. The two guide blades 20 are obliquely mounted within the bottom shell and are disposed opposite each other to form a restraining chute 3. The massager 300 further comprises a battery 24 for powering the massager and a circuit board 25 for controlling the operation of the massager.

[0056] The advantages of the present invention are as follows: compared with a vertically set deflection constraint rod, an inclined deflection constraint rod can reduce the height of the massage arm assembly as a whole, thereby reducing the overall thickness of the movement. The rotatable massage head will roll when it is subjected to force during massage, and will not cause the massage head to slide and rub directly against the human skin without rolling, resulting in an unpleasant experience of rubbing the skin. In addition, the massage head can roll, the friction force is small, and the surface friction loss of the massage head is small, which can increase the service life. The detachable eccentric wheel assembly can simplify the mold on the one hand, and on the other hand, it can facilitate and independently control the roundness and dimensional accuracy of the matching cylindrical surfaces of the first eccentric wheel and the second eccentric wheel. The better the roundness, the higher the accuracy and the more precise the matching of the shoulder and neck massage arm and the trapezius massage arm, the less likely it is to have large gaps and shake, thereby generating abnormal noise.
