[0036] Please see Figures 1 to 19 This utility model provides a massager, including: a housing 1, a support shaft 2, a kneading driven wheel 3, two massage arm assemblies 4, and two kneading eccentric wheel groups 5 for driving the massage arm assemblies 4 to perform massage actions; the two massage arm assemblies 4 are symmetrical about the central plane 23 of the massager.

[0037] The kneading driven wheel 3 and the kneading eccentric wheel group 5 are fixedly connected to the outer wall of the support shaft 2. Each of the two kneading eccentric wheel groups 5 is provided with a support part 6. The support part 6 is integrally formed with the kneading eccentric wheel group 5. The support part 6 is coaxial with the kneading driven wheel 3. The two support parts 6 and the kneading driven wheel 3 are circumferentially anti-rotation connected to drive the support part 6 to rotate. The support part 6 is rotatably connected to the housing 1.

[0038] This invention relies on the support portion 6 on the side of the kneading eccentric wheel assembly 5 to be rotatably connected to the housing 1. The two ends of the support shaft 2 no longer rely on the housing 1 for support, eliminating the support components at both ends of the kneading shaft in the prior art. This allows the two ends of the support shaft 2 to be suspended in the air, eliminating the need for vertical downward space at both ends of the support shaft 2, simplifying the structure of the housing 1, reducing the number of overall parts in the massage mechanism, and helping to reduce the overall size of the massage mechanism, making it more compact. Furthermore, in this invention, the support shaft 2 does not function as a rotating component providing torque, but only as a supporting reinforcement for the kneading eccentric wheel assembly 5 and the kneading driven wheel 3, simplifying the structure of the support shaft 2 and reducing the material requirements for the support shaft 2.

[0039] Specifically, the two support parts 6 are divided into a first support part 61 and a second support part 62, and the two kneading eccentric wheel groups 5 are divided into a first kneading eccentric wheel group 51 and a second kneading eccentric wheel group 52. The first support part 61 is located on the side of the first kneading eccentric wheel group 51, and the second support part 62 is located on the side of the second kneading eccentric wheel. The side of the kneading driven wheel 3 is provided with an external spline section 31, an anti-rotation cylindrical pin (not shown in the figure) or a flat key (not shown in the figure). The first support part 61 is provided with a corresponding internal spline hole (not shown in the figure), a cylindrical pin groove (not shown in the figure) or a flat key groove (not shown in the figure). The external spline section 31 is connected in the internal spline hole, or the anti-rotation cylindrical pin is connected in the cylindrical pin groove, or the flat key is connected in the flat key groove. The other side of the kneading driven roller 3 is provided with a key strip segment 32, such as Figure 6 As shown, the key bar segment 32 has a protrusion 33, and the second support portion 62 has a receiving groove 621. Two abutment walls 622 are provided within the receiving groove 621. The two abutment walls 622 are configured such that when the kneading driven wheel 3 rotates forward, the protrusion 33 of the key bar segment 32 abuts against one of the abutment walls 622, thereby driving the two sets of massage arm assemblies 4 to move in a mirror image of each other. Mirror image motion means: pressing... Figure 14 From the perspective shown, the massage ends of the two neck massage arms 41 move closer to each other or further apart, and the massage ends of the two shoulder massage arms 42 move upward or downward simultaneously.

[0040] When the kneading driven roller 3 reverses, after the key strip 32 rotates 180°, the protrusion 33 of the key strip 32 abuts against another abutting wall 622, thereby driving the two sets of massage arm assemblies 4 to move in a non-mirror-image manner. Non-mirror-image movement means: pressing... Figure 14 From the perspective shown, the two neck massage arms 41 swing to the left or right simultaneously, while the two shoulder massage arms 42 move up and down alternately.

[0041] When the kneading driven wheel 3 reverses, the first kneading eccentric wheel group 51 reverses synchronously with the kneading driven wheel 3. At the same time, the protrusion on the key strip segment 32 first separates from one of the abutting walls 622. The second kneading eccentric wheel group 52 does not rotate. After the kneading driven wheel 3 reverses 180 degrees, the protrusion 33 contacts the other abutting wall 622, which drives the second kneading eccentric wheel group 52 to rotate again, so as to drive the two sets of massage arm assemblies 4 to achieve non-mirror motion.

[0042] Specifically, it also includes: a tapping shaft 7 and a massage drive 8, wherein the tapping shaft 7 is rotatably connected to the housing 1, and the massage drive 8 is connected to the kneading driven wheel 3 and the tapping shaft 7 to drive the kneading driven wheel 3 and the tapping shaft 7 to rotate; The massage arm assembly 4 includes: a neck massage arm 41, a shoulder massage arm 42, a pin 43, and a shoulder massage rotatable seat 44; The neck massage arm 41 and shoulder massage rotating seat 44 are connected to the kneading eccentric wheel assembly 5. The two ends of the tapping shaft 7 are respectively provided with eccentric sections 71. The shoulder massage arm 42 is provided with a mounting hole 421, in which a first bearing 9 is installed. The first bearing 9 is sleeved on the outer wall of the eccentric section 71. The shoulder massage arm 42 is also connected to a bearing cap 10 for constraining the outer ring of the first bearing 9. The eccentric section 71 is spirally connected to a second nut 11 for constraining the inner ring of the first bearing 9. The shoulder massage arm 42 has a hinge hole 422, in which a pin-shaft rubber shock-absorbing sleeve 12 is installed. The pin 43 is located inside the pin-shaft rubber shock-absorbing sleeve 12, and both ends of the pin 43 are connected to the shoulder massage rotating seat 44. The shoulder massage rotating seat 44 pulls the massage end of the shoulder massage arm 42 to move up and down reciprocally. When the tapping shaft 7 rotates, it enables the shoulder massage arm 42 to produce a tapping massage effect. The setting of the pin-shaft rubber shock-absorbing sleeve 12 can reduce the transmission to the shoulder massage rotating seat 44.

[0043] The neck massage arm 41 and the shoulder massage arm 42 are respectively equipped with rubber massage heads at their massage ends. Each neck massage arm 41 is equipped with a first massage head 13 and a second massage head 14, and the shoulder massage arm 42 is equipped with a third massage head 15.

[0044] Specifically, the massage drive component 8 includes a motor 81, a kneading drive gear shaft 82, a kneading drive gear set 83, a tapping drive gear shaft 84, a tapping drive gear set 85, a tapping driven gear 86, and a one-way bearing 87.

The output shaft of the motor 81 is a worm shaft 88, which is meshed with the first kneading drive gear 831 and the first striking drive gear 851. The first kneading drive gear 831 and the first striking drive gear 851 are helical gears. Of course, the first kneading drive gear 831 and the first striking drive gear 851 can also be replaced with corresponding worm wheels.

[0045] The second kneading drive gear 832 is meshed with the kneading driven wheel 3. The kneading driven wheel 3 is rotatably connected to the outer wall of the support shaft 2. The outer wall of the striking shaft 7 is fitted with a one-way bearing 87. The striking driven gear 86 is fitted on the outside of the one-way bearing 87.

A rubber shock-absorbing sleeve 17 for the striking shaft is connected to the outer wall of the slewing bearing 16. The rubber shock-absorbing sleeve 17 for the striking shaft is connected between the middle shell 102 and the bottom shell 103. The rubber shock-absorbing sleeve 17 for the striking shaft can reduce the vibration transmitted to the housing 1. The support part 6 is rotatably connected between the upper shell 101 and the middle shell 102. The middle shell 102 has a guide groove 104. The neck massage arm 41 is provided with a guide 45. The guide 45 is slidably connected in the guide groove 104. The guide groove 104 of the neck massage arm 41 is integrally formed on the middle shell 102, eliminating the need for separate guide constraints or forming the guide groove 104 on the outer shell of the massager, which can save the weight of parts and the number of molds.

[0048] The kneading eccentric wheel assembly 5 is equipped with a sensing magnet 18, and the middle shell 102 is equipped with a Hall plate 19. The Hall plate 19 cooperates with the sensing magnet 18 to detect the kneading massage position.

[0049] Specifically, the worm shaft 88 includes a worm segment 881 and a smooth shaft segment 882. A worm sleeve 883 is fitted onto the smooth shaft segment 882.
