The driving assembly 300 includes a transmission member 310 coupled to the massage wheel set 200 and a driver 320 mounted in the casing 100 for driving the transmission member 310 to rotate. 320 is a motor in this embodiment. The massage wheel set 200 includes a connecting bracket 210 coupled to the transmission member 310 and at least two rotating massage heads 220, specifically, in the embodiment of the present invention Among them, the rotary massage head 220 is provided with two. Each of the rotary massage heads 220 is rotatably connected to the connecting bracket 210. The extending direction of the rotation axis of each rotary massage head 220 is staggered with the extending direction of the rotation axis of the transmission member 310, and a gap is left between the rotary massage head 220 and the casing 100. .

In the embodiment of the present invention, the mechanical rotary massager further includes an anti-pinch structure 400, and the anti-pinch structure 400 includes an anti-pinch protection seat 410 and a rotation protection plate 420, each of which is made of a hard material, and an anti-pinch protection seat. The bottom of the anti-pinch protection seat 410 is fixedly connected to the casing 100, the rotary massage head 220 is at least partially placed in the bowl cavity, and the rotary protection plate 420 is closed to the bowl cavity. The bowl mouth is fixedly connected with the connecting bracket 210 to rotate with the connecting bracket 210, and the rotating massage head 220 is avoided, and the transmission member 310 is disposed in the bowl cavity.

[0027] Based on this structure, during use, the rotary massage head 220 is in contact with the human body, and the driver 320 drives the transmission member 310 to rotate and drives the drive assembly 300 to rotate integrally around the rotation axis of the transmission member 310, wherein, due to the rotary massage heads The extending direction of the rotation axis of 220 is staggered with the extending direction of the rotation axis of the transmission member 310, and the rotary massage head 220 is in contact with the human body, and each of the rotary massage head 220 and the transmission member 310 rotates around the rotation axis of the transmission member 310.吋, will also rotate about the respective axis of rotation, wherein, due to the anti-pinch structure 400, the anti-pinch structure 400 fills the gap between the rotating massage head 220 and the casing 100, preventing the hand from being inserted into the rotating massage head 220 and The gap between the cabinets 100 prevents pinching.

In the embodiment of the present invention, the anti-pinch protection seat 410 is disposed in a bowl shape, and the anti-pinch protection seat 410 is provided with structural reinforcing ribs on the outer bowl wall thereof. Thus, it is also advantageous to reduce the structural strength of the anti-pinch protection seat 410 while reducing the use of the material of the anti-pinch protection seat 410.

[0029] In the embodiment of the present invention, the rotating protection plate 420 and the connecting bracket 210 are configured in a body structure. Thus, it is advantageous to increase the strength of the connection between the spin protection plate 420 and the connection bracket 210.

[0030] Referring to FIG. 4 and FIG. 5, in the embodiment of the present invention, the connecting bracket 210 is provided with a ball bowl cavity, and the connecting bracket 2 10 is arranged in the direction of the bowl opening of the ball bowl cavity. The transmission member 310 includes a shaft body 311, a ball head 312 connected to the shaft body 311 at the end and engaged with the ball bowl cavity, and a spherical surface connected to the outer end of the ball head 312 and the stop position The groove-fitting stop protrusion 313 has a groove width larger than the width of the stop protrusion 313. During the massage process, the rotary massage head 220 can be in contact with the human body directly or through clothing or the like, and the drive assembly 300 drives the transmission member 310 and the ball head 312 - and rotates, wherein, due to the ball head 312 and the connection bracket 210 The connection is a ball joint structure, and the groove width of the stop groove is larger than the stop protrusion From the width of 313, the stop protrusion 313 can move in a small range within the stop groove, so that the connecting bracket 210 and the transmission member 310 can also rotate relative to each other in a small range, so that when the rotary massage head 220 encounters a different body The surface 吋, the state of the force of the rotary massage head 220 will change, and the rotary massage head 220 will also be offset to an inclined state that is adapted to the outer surface of the human body, thereby improving the comfort of the massage.

[0031] Further, referring to FIG. 4 to FIG. 6, the mechanical rotary massager includes an elastic member 500 disposed in a cylindrical shape and sleeved with the shaft body 311. The transmission member 310 includes a second end connected to the shaft body 311. The limiting plate 3 14, the elastic member 500 is located between the connecting bracket 210 and the limiting plate 314, and elastically abuts the connecting bracket 210 and the limiting plate 314. The elastic member 500 is disposed in a cylindrical shape, and the contact surface of the elastic member 500 and the connecting bracket 210 is arranged in an annular shape. Thus, when the rotating massage head 220 is subjected to an external force, the external force will indirectly cancel the elastic member 500 through the connecting bracket 210. The elastic restoring force, the connecting bracket 210 will be deflected relative to the ball head 312, and the rotating massage head 220 is offset to fit the outer surface of the human body, and when the rotating massage head 220 is not subjected to an external force, the connecting bracket 210 is Under the elastic restoring force of the elastic member 500, the positional relationship between the connecting bracket 210 and the ball head 312 will return to the positional relationship before the connecting bracket 210 and the ball head 312 are deflected relative to each other, and the rotary massage head 220 will also be offset. From the position state before the external force is received, based on this, the elastic member 500 functions as a reset for the massage wheel set 200.

[0032] Further, the connecting bracket 210 includes a cylinder 211 and a cylinder cover 212 detachably coupled to the upper portion of the cylinder 211. The inner cylinder cavity of the cylinder 211 and the cylinder cover 212 together form a bowl cavity, and each rotary massage head 220 is connected to the cylinder 211, and the rotary protection plate 420 is connected to the cylinder 211. Based on this structure, the ball head 312 can be assembled to the barrel 211 after the assembly, and the sleeve 212 can be fitted to the barrel 211, which reduces the assembly difficulty.

Referring to FIG. 2 to FIG. 6 , in the embodiment of the present invention, the extending direction of the rotation axis of each rotary massage head 220 is perpendicular to the extending direction of the axis of the transmission member 310, and the rotation axis of each rotary massage head 220 is The extending direction is divergently disposed around the axis of the transmission member 310.
