[0021] For the convenience of those skilled in the art, the present application is further described below in conjunction with the embodiments, and the content mentioned in the embodiments is not a limitation on the present application.

[0022] As shown in the drawings, Figures 1 to 6 A hammering type neck and shoulder massager includes a shell 1, a piano box shell 2 fixedly installed in the shell 1 and a first rotating shaft 21 movably pivoted to the piano box shell 2. The piano box shell 2 movably pivots a second rotating shaft 22, a third rotating shaft 23 and a driving assembly 3 for driving the first rotating shaft 21, the second rotating shaft 22 and the third rotating shaft 23 to rotate. The first rotating shaft 21 movably installs a first torsional swing arm 4 at both ends thereof, the second rotating shaft 22 movably installs a second torsional swing arm 5 at both ends thereof, and the third rotating shaft 23 movably installs an eccentric wheel 24 and a linkage ring 25 sleeved on the eccentric wheel 24 at both ends thereof. The linkage ring 25 is movably hinged to the middle portion of the second torsional swing arm 5 through a connecting rod 51, and the outer ends of the first torsional swing arm 4 and the second torsional swing arm 5 movably install a massage head 6.

[0023] In actual application, the hammering type neck and shoulder massager is fixed to the neck and shoulder portion through a soft binding belt, and under the action of the driving assembly 3, the first rotating shaft 21, the second rotating shaft 22 and the third rotating shaft 23 independently rotate at a set speed reduction ratio. The first rotating shaft 21 and the second rotating shaft 22 drive the first torsional swing arm 4 and the second torsional swing arm 5 to swing, thereby driving the massage head 6 at the outer ends thereof to simulate manual massage at the neck and shoulder portion of the human body, achieving the purpose of kneading the neck and shoulder portion. When the third rotating shaft 23 drives the eccentric wheel 24 to rotate, the linkage ring 25 drives the second torsional swing arm 5 to swing at high speed through the connecting rod 51, and forms high-frequency reciprocating vibration at the outer end of the second torsional swing arm 5, achieving the effect of increasing shoulder massage on the existing neck and shoulder massager, and having strong practicability.

[0024] In this embodiment, the first rotating shaft 21, the second rotating shaft 22, and the third rotating shaft 23 all extend from both ends of the gearbox housing 2. The drive assembly 3 includes a motor 31 and a transmission shaft 32 detachably connected to the main shaft of the motor 31. The first rotating shaft 21 and the second rotating shaft 22 are connected to the transmission shaft 32 via a reduction gear set, and the third rotating shaft 23 is connected to the transmission shaft 32 via a belt 33 or a reduction gear. Specifically, the reduction gear set includes a worm 34 disposed on the transmission shaft 32, a worm wheel 35 meshing with the worm 34, a small gear 36 coaxially fixed with the worm wheel 35, a large gear 37 connected to the small gear 36, and two driving bevel gears 38 coaxially fixedly connected with the large gear 37. The first rotating shaft 21 and the second rotating shaft 22 are both fixedly equipped with driven bevel gears 39, and the two driving bevel gears 38 mesh with the two driven bevel gears 39.

[0025] The main shaft of the motor 31 is detachably connected to the transmission shaft 32 via a coupling, spline structure, or flat key structure, and drives the transmission shaft 32 to rotate. Then, the worm gear 34 and the turbine drive the large gear 37 and the small gear 36 to rotate. Finally, the two driving bevel gears 38 and the two driven bevel gears 39 drive the first rotating shaft 21 and the second rotating shaft 22 to rotate respectively, thereby realizing the torsional driving function of the first torsional arm 4 and the second torsional arm 5. The structure is simple and the reliability is high.

[0026] In this embodiment, the third rotating shaft 23 is coaxially fixedly equipped with a large pulley 20, and the transmission shaft 32 is provided with a small pulley 55. The large pulley 20 and the small pulley 55 are connected by a synchronous belt or belt 33, which greatly reduces the transmission noise between the transmission shaft 32 and the third rotating shaft 23, simplifies the internal assembly structure of the gearbox housing 2, makes the whole machine lighter, and has a higher cost performance.

[0027] In this embodiment, the third rotating shaft 23 is equipped with a one-way bearing 26, and the large pulley 20 is fixedly installed on the one-way bearing 26. When the motor 31 rotates in the forward direction, the large pulley 20 can drive the third rotating shaft 23 to rotate normally, so as to ensure the normal percussion massage action of the second torsion arm 5. When the percussion massage action is not required, it is only necessary to control the motor 31 to reverse. At this time, the large pulley 20 cannot drive the third rotating shaft 23 to rotate, and the eccentric wheel 24 and the connecting rod 51 cannot work. The second torsion arm 5 only has a torsion action and no percussion massage effect, which takes into account the user's massage needs that do not require percussion and is highly practical.

[0028] In this embodiment, a ball cup sleeve is provided in the middle of the second torsional arm 5, and a ball head 52 is provided at one end of the connecting rod 51. The ball head 52 is movably embedded in the ball cup sleeve. By utilizing the structure of the ball head 52 and the ball cup sleeve, the linkage connection between the connecting rod 51 and the second torsional arm 5 can be realized without affecting the torsional swing action, resulting in high stability and reliability.

[0029] In this embodiment, offset wheels 27 are fixedly installed at the ends of the first rotating shaft 21 and the second rotating shaft 22, and torsion rings 28 are provided at the roots of the first torsion arm 4 and the second torsion arm 5. The torsion rings 28 of the first torsion arm 4 and the second torsion arm 5 are respectively movably fitted onto the offset wheels 27. Specifically, the distance between the axis of the offset wheel 27 and the axis of the outer wheel circumference is greater than 5 mm, realizing the radial swing of the first torsion arm 4 and the second torsion arm 5 relative to the rotating shaft; the angle between the rotation center axis of the outer wheel circumference of the offset wheel 27 and the rotation center axis of the first rotating shaft 21 or the second rotating shaft 22 is 75 to 85 degrees, realizing the torsion action of the first torsion arm 4 and the second torsion arm 5. That is, during the rotation process of the offset wheel 27, the first torsion arm 4 and the second torsion arm 5 simultaneously twist and swing massage action is realized, and the massage comfort is significantly enhanced.

[0030] In this embodiment, the outer ends of the first swing arm 4 and the second swing arm 5 are both equipped with massage heads 6. The massage heads 6 are made of flexible foam or are composed of movable rollers, which further improves the comfort of the massage heads 6 when they come into contact with the skin.

[0031] In this embodiment, the outer wall of the torsion ring 28 of the first torsion arm 4 is provided with an anti-rotation post 29, and the inner wall of the housing 1 is provided with an elongated groove 11 arranged parallel to the first rotating shaft 21. The anti-rotation post 29 is movably embedded in the elongated groove 11 to prevent the first torsion arm 4 from rotating synchronously with the bias wheel 27. At the same time, it also strengthens the support strength of the first torsion arm 4 and prevents the first torsion arm 4 from falling down and affecting the massage experience, thus having good reliability.
