Description

technical field

[0001] The invention relates to the technical field of electric toothbrush components, in particular to an oscillating motor with feedback output swing used in conjunction with an electric toothbrush. Background technique

[0002] Electric toothbrush is a new product that has become popular in recent years, and has set off a revolution in the field of oral health care abroad. With the widespread popularity of electric toothbrushes in our country, and with the improvement of people's awareness of it, electric toothbrushes will also become an important member of public health care products. The survey shows that compared with ordinary toothbrushes, electric toothbrushes are more scientific and effective, and can more thoroughly remove plaque, reduce gingivitis and gingival bleeding. Electric toothbrushes use the rapid reciprocating rotation of the motor output shaft to generate high-frequency vibration of the brush head. , so that the toothpaste is decomposed ...
