[0027] The utility model makes further detailed explanation in combination with the drawings and specific embodiment:

[0028] Reference Figures 1 to 5 A shoulder and neck massager, including shell 20, movement assembly 10 and two massage assemblies 30, the movement assembly 10 is located in the shell 20, two the massage assembly 30 is located in shell 20 and is connected with the movement assembly 10. The massage assembly 30 includes first massage piece 31 and second massage piece 32, the first massage piece 31 is equipped with eccentric hole 314, the first massage piece 31 is driven connection through eccentric hole 314 with the movement assembly 10, the movement assembly 10 drives the eccentric rotation of first massage piece 31. The one end of second massage piece 32 is connected with first massage piece 31, drives second massage piece 32 to rotate through first massage piece 31, the lower bottom surface of second massage piece 32 is equipped with limit post 321, the upper surface of shell 20 is equipped with sliding limit slot 21, and limit post 321 slides in sliding limit slot 21. The second massage piece 32 is limited the movement track of second massage piece 32 under the action of sliding limit slot 21.

[0029] The core assembly 10 comprises a double worm motor 11, two turbines 12, two transmission gears 13, two turbine mounting shafts 14 and two transmission gear mounting shafts 15. The motor 11, the turbine mounting shaft 14 and the transmission gear mounting shaft 15 are arranged in the housing 20. The turbine mounting shaft 14 is arranged at the center of the turbine 12, and the transmission gear mounting shaft 15 is arranged at the center of the transmission gear 13 and fixedly connected with the transmission gear 13. The two worms on the motor 11 drive a turbine 12 respectively, and each turbine 12 meshes with a transmission gear 13. The housing 20 is provided with a mounting groove 22, and the lower end of the transmission gear mounting shaft 15 is arranged in the mounting groove 22, and the transmission gear mounting shaft 15 is rotationally connected with the mounting groove 22. The transmission gear 13 drives the transmission gear mounting shaft 15 to rotate, and the transmission gear mounting shaft 15 drives the first massage member 31 to eccentrically rotate. The transmission gear mounting shaft 15 serves as the mounting shaft of the transmission gear 13 to realize the rotation of the transmission gear 13 around the center of the transmission gear mounting shaft 15, and is arranged in the eccentric hole 314 of the first massage member 31 to realize the eccentric rotation of the first massage member 31, thereby achieving the purpose of one shaft with two functions.

[0030] The first massage member 31 further comprises a first base 311, a first connecting arm 312 and a first massage head 313 connected in sequence. The eccentric hole 314 is vertically arranged on the first base 311, and the upper portion of the transmission gear mounting shaft 15 is arranged in the eccentric hole 314 and fixedly connected with the eccentric hole 314. The fixed connection mode can be that the upper end of the transmission gear mounting shaft 15 is provided with a positioning protrusion 151, the eccentric hole 314 is provided with a positioning hole (not shown) matched with the positioning protrusion 151, and the positioning protrusion 151 and the positioning hole are matched to prevent the first base 311 from rotating relative to the transmission gear mounting shaft 15, so that the first massage member 31 is driven to eccentrically rotate by the transmission gear mounting shaft 15. More preferably, in the embodiment, the end of the first connecting arm 312 connected with the first base 311 is fixed above the first base 311, and therefore the eccentric hole 314 passes through the first base 311 and the first connecting arm 312 at the same time, which increases the penetration depth of the transmission gear mounting shaft 15 in the eccentric hole 314 and improves the stability of the eccentric rotation of the first massage member 31. The second massage member 32 further comprises a second connecting hole 324, a second connecting arm 322 and a second massage head 323 connected in sequence, and the first base 311 is sleeved in the second connecting hole 324. When the first base 311 eccentrically rotates, it drives one end of the second massage member 32 to rotate with the eccentric hole 314 as the center. Then, the massage track of the second massage head 323 is limited by the cooperation of the limiting column 321 on the second massage member 32 and the sliding limiting groove 21 on the upper surface of the shell 20. The limiting column 321 can be arranged on the lower bottom surface of the second connecting arm 322, and the sliding limiting groove 21 can be designed in a wave shape. The wave-shaped sliding limiting groove 21 is composed of at least two continuous and opposite arc-shaped sliding tracks, for example, an S-shaped sliding limiting groove 21 can be used. In this way, the second massage member 32 swings left and right with a small amplitude while moving up and down under the driving of the first massage member 31. When the two second massage heads 323 arranged left and right are at the bottom of the arc-shaped sliding track A, the distance between the two second massage heads 323 is maximum or minimum. When the distance is minimum, the kneading force is slightly increased, and when the distance is maximum, the kneading force is slightly reduced. Therefore, the kneading force of the two second massage heads 323 gradually changes between strong and weak during kneading massage, improving the comfort of kneading.

[0031] In order to prevent the second connecting arm 322 from being raised up and down, the second massage member 32 further comprises an arm limiting member 325 arranged above the second connecting arm 322 and fixed at both ends on the shell 20, and the second connecting arm 322 passes through the arm limiting member 325. The stability of the second connecting arm 322 during movement is improved by the limiting action of the arm limiting member 325, and the second connecting arm 322 can be a U-shaped element.

[0032] The first massage member 31 further comprises a sealing plate 315 fixed below the first base 311. In the embodiment, the sealing plate 315 is fixedly connected with the first base 311 by screws, and further serves as an oil seal to prevent dust and other foreign matters from entering the first base 311, thereby ensuring smooth eccentric rotation.

[0033] The housing 20 can further be provided with a circuit control module 40 and a power supply module (not shown), the circuit control module 40 controls the charge and discharge of the power supply module, the start and stop of the motor 11, etc., which is a simple control, and the power supply module supplies power for the movement core assembly 10.

[0034] The working principle of the utility model is as follows: after the shoulder and neck massager is powered on, the motor 11 drives the turbine 12 and the transmission gear 13 to rotate. The first massage head 313 rotates around the eccentric hole 314 under the action of the transmission gear mounting shaft 15 and the eccentric hole 314, realizing rotary push massage. At the same time, when the two first massage heads 313 arranged left and right gradually move towards the center from the most separated position, horizontal kneading massage is realized. One end of the second massage head 323 rotates around the eccentric hole 314 driven by the first massage member 31, and the other end of the second massage head 323 generally moves in an up-down mode, and under the cooperation of the sliding limiting groove 21 and the limiting column 321, the distance between the two second massage heads 323 gradually changes from large to small and then from small to large, or from small to large and then from large to small during a single movement (i.e. from up to down or from down to up) of the second massage head 323. Not only the vertical push is realized, but also the horizontal kneading massage is realized, and the kneading process also gradually changes in strength, greatly improving the massage comfort.

[0035] The above is only a specific embodiment of the utility model, and does not limit the patent range of the utility model, any equivalent structural transformation or direct or indirect application in other related technical fields based on the contents of the utility model specification and drawings is also included in the patent protection range of the utility model.
