[0002] An electric toothbrush is a common oral care tool. Its simple operation and remarkable oral cleaning effect have been widely applied to the population. An electric toothbrush makes the brush head generate high-frequency vibrations through the rapid rotation or vibration of the motor core, instantly decomposes toothpaste into fine foam, and deeply cleans the tooth gaps. At the same time, the vibration of the bristles can promote blood circulation in the oral cavity and has a massaging effect on the gingival tissue.
