Electric toothbrush bearing

There are two kinds of electric toothbrushes. One is rotary electric toothbrush, which uses the internal motor to drive the circular brush head to rotate. Another is the acoustic electric toothbrush, which uses the motor to drive the toothbrush head to swing left and right at high speed. The toothbrush head will produce mechanical vibration, that is, sound waves, so it is called acoustic electric toothbrush. The electric toothbrush bearing is an essential transmission part of the two electric toothbrushes. Therefore, the quality of the electric toothbrush bearing plays a decisive role in the quality and service life of the electric toothbrush.
The micro motor used by the electric toothbrush is a DC motor. When brushing teeth, the motor should not only vibrate and rotate stably, but also can not swing left and right, and the current should be small. Ordinary bearings will increase the current of the electric toothbrush motor, swing left and right and unstable, which can not meet the requirements.
