It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

An embodiment of the present invention provides a mechanical rotary massager.

Please refer to FIG. 2 to FIG. 6 , the mechanical rotary massager includes a casing 100 , a massage wheel set 200 and a drive assembly 300 , wherein the casing 100 can usually be made of plastics such as PE and PC. The massage wheel set 200 is located on the upper side of the casing 100 . The drive assembly 300 is installed in the casing 100 and is used to drive the massage wheel set 200 to rotate. The drive assembly 300 includes a transmission member 310 connected with the massage wheel set 200 and a driver 320 installed in the casing 100 and used to drive the transmission member 310 to rotate. 320 is a motor in this embodiment. The massage wheel set 200 includes a connecting bracket 210 connected to the transmission member 310 and at least two rotating massage heads 220 , specifically, in the embodiment of the present invention, there are two rotating massage heads 220 . Each rotating massage head 220 is rotatably connected with the connecting bracket 210, the extension direction of the rotation axis of each rotation massage head 220 and the extension direction of the rotation axis of the transmission member 310 are interlaced, and there is a gap between the rotation massage head 220 and the casing 100 .

In the embodiment of the present invention, the mechanical rotary massager also includes an anti-pinch structure 400. The anti-pinch structure 400 includes an anti-pinch protection seat 410 and a rotating protection plate 420 made of hard materials. The anti-pinch protection seat 410 is provided with The bowl cavity with the opening facing upwards, the underside of the anti-pinch protection seat 410 is fixedly connected with the casing 100, the rotating massage head 220 is at least partly placed in the bowl cavity, and the rotating protection plate 420 covers the bowl mouth of the bowl cavity, and is connected with the The connecting bracket 210 is fixedly connected to rotate together with the connecting bracket 210 , and avoids the rotating massage heads 220 , and the transmission member 310 is installed in the bowl cavity.

Based on this structure, during use, when the rotating massage head 220 touches the human body, the driver 320 drives the transmission member 310 to rotate and drives the drive assembly 300 to rotate around the rotation axis of the transmission member 310 as a whole. The extension direction of the axis is interlaced with the extension direction of the rotation axis of the transmission part 310, and the rotating massage head 220 is in conflict with the human body. When each rotation massage head 220 and the transmission part 310 rotate around the rotation axis of the transmission part 310, The respective axis of rotation rotates, wherein, due to the setting of the anti-pinch structure 400, the anti-pinch structure 400 fills the gap between the rotating massage head 220 and the casing 100, so as to avoid manual insertion between the rotating massage head 220 and the casing 100 gap to prevent being pinched.

In the embodiment of the present invention, the anti-pinch protection seat 410 is arranged in a bowl shape, and the anti-pinch protection seat 410 is provided with structural reinforcing ribs on the outer wall of the bowl. In this way, while reducing the material usage of the anti-pinch protection seat 410 , it is also beneficial to enhance the structural strength of the anti-pinch protection seat 410 .

In the embodiment of the present invention, the rotation protection plate 420 and the connection bracket 210 are integrally arranged. In this way, it is beneficial to improve the connection strength between the rotation protection plate 420 and the connection bracket 210 .

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 210 is provided with a stop groove arranged in the direction of the bowl opening of the ball bowl cavity on the cavity wall of the ball bowl cavity (Fig. not marked in), the transmission part 310 includes a shaft body 311, a ball head 312 connected to one end of the shaft body 311 and matched with the ball bowl cavity, and a stop protrusion connected to the outer spherical surface of the ball head 312 and matched with the stop groove 313 , the groove width of the stop groove is greater than the width of the stop protrusion 313 . During the massage process, the rotating massage head 220 can be in contact with the human body directly or through clothing, etc., and the drive assembly 300 drives the transmission member 310 and the ball head 312 to rotate together, wherein, due to the contact between the ball head 312 and the connecting bracket 210 The connection is a ball joint connection structure, and the groove width of the stop groove is larger than the width of the stop protrusion 313, and the stop protrusion 313 can move within a small range in the stop groove, so that the connecting bracket 210 and the transmission member 310 can also move in a small range. Relatively rotate in a small range, so that when the rotating massage head 220 encounters different curved surfaces of the human body, the force state of the rotating massage head 220 will change, and the rotating massage head 220 will also shift to an inclined state suitable for the outer surface of the human body , thus improving the comfort of massage.

Further, referring to Fig. 4 to Fig. 6, the mechanical rotary massager includes an elastic member 500 arranged in a cylindrical shape and sleeved with the shaft body 311, and the transmission member 310 includes a stopper connected to the other end of the shaft body 311.

Wherein, the elastic member 500 is arranged in a cylindrical shape, and the contact surface between the elastic member 500 and the connecting bracket 210 is arranged in a ring shape, so that when the rotating massage head 220 is subjected to an external force, the external force will indirectly offset the elastic member 500 through the connecting bracket 210 elastic recovery force, the connecting bracket 210 will deflect relative to the ball head 312, and the rotating massage head 220 will deviate to adapt to the outer surface of the human body. When the rotating massage head 220 is not subjected to external force, the connecting bracket 210 will Under the action of the elastic recovery 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 relative deflection of the connecting bracket 210 and the ball head 312, and the rotating massage head 220 will also be offset. Based on the position state before receiving the external force, it can be known that the elastic member 500 has the function of restoring the massage wheel set 200 .

Further, the connection bracket 210 includes a cylinder body 211 and a cylinder cover 212 detachably connected to the upper part of the cylinder body 211. The inner cylinder cavity of the cylinder body 211 and the cylinder cover 212 together form a ball bowl cavity, and each rotating massage head 220 is connected to The cylinder body 211 and the rotation protection plate 420 are connected to the cylinder body 211 . Based on this structure, during the assembly process, the ball head 312 can be assembled to the cylinder body 211 first, and then the cylinder cover 212 can be fitted to the cylinder body 211, which reduces the difficulty of assembly.

Please refer to Fig. 2 to Fig. 6, in the embodiment of the present invention, the extending direction of the axis of rotation of each rotating massage head 220 is perpendicular to the extending direction of the axis of the transmission member 310, and the extending direction of the axis of rotation of each rotating massage head 220 is set at The axis of the transmission member 310 is arranged in a diverging shape at the center.

In the embodiment of the present invention, the mechanical rotary massager includes an outer cover (not shown in the figure) made of soft rubber for covering the casing 100 and the massage wheel set 200 together. Through the arrangement of the outer cover, the outer cover can directly prevent dust, water and other sundries from entering the casing 100, and can play a protective role.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention Inside.
