Description
Technical Field

Background
The electric face cleaning instrument sold in the current market achieves the effect of cleaning the facial skin by driving the brush head. The rotary electric face cleaning instrument has no vibration massage effect, and has large rotary torque force and single rotary direction, thereby causing great damage to facial skin.

Detailed Description
In order to further explain the technical solution of the present invention, the following detailed description is made by specific examples.
Referring to fig. 1-2, a face cleaning instrument comprises a shell, a brush head 1 and a brush head speed reducing mechanism 2;
this brush head reduction gears 2 includes: a motor 21, a deflection transmission structure 22 and a deflection shaft 23;
the deflection transmission structure 22 includes an eccentric rotation member 221 linked with the output rotation shaft of the motor 21, and a deflection block 222 driven by the eccentric rotation member 221 to swing; the eccentric rotation member 221 is eccentrically fixed to an output rotation shaft of the motor 21 to be driven by the rotation shaft to eccentrically rotate. One end of the deflection block 222 is connected to the eccentric rotation member 221, and the other end of the deflection block 222 is connected to the deflection shaft 23; the deflection block 222 drives the deflection shaft 23 to perform a bidirectional swinging motion around the axial direction thereof, and the deflection shaft 23 drives the brush head 1 to move. The brush head speed reducing mechanism 2 has a simpler structure, is beneficial to the light weight and the miniaturization of the face cleaning instrument, and also increases the durability of the face cleaning instrument.
In order to realize the unidirectional rotation of the brush head 1, the present embodiment further includes a unidirectional rotation transmission member 24, the yaw axis 23 is connected to the unidirectional rotation transmission member 4, the unidirectional rotation transmission member 24 is connected to the brush head 1, and the unidirectional rotation transmission member 24 converts the bidirectional yaw motion of the yaw axis 23 into unidirectional rotation and then drives the brush head 1 to rotate.
Specifically, in this embodiment, the eccentric rotating member 221 is an eccentric wheel, and an eccentric hole thereof is linked with an output rotating shaft of the motor 21. Thus, the output shaft of the motor 21 can drive the eccentric wheel to rotate, and the eccentric wheel shows eccentric rotation because the eccentric hole is arranged at the eccentric position of the eccentric wheel.
In order to realize the deflection motion of the deflection block 222, an oval through hole 2221 for accommodating the eccentric wheel is arranged in the deflection block 222 in a direction parallel to the eccentric shaft; the eccentric wheel pushes against the inner sidewall of the through hole 2221 during eccentric rotation to drive the deflection block 222 to deflect.
