Description

Technical Field

[0001] The utility model relates to the technical field of electric toothbrushes, in particular to an electric toothbrush. Background Art

[0002] An electric toothbrush consists of a motor, a brush head, and a power source. The rapid rotation or vibration of the motor core causes the brush head to generate high-frequency vibrations, breaking the toothpaste into fine foam to clean the gaps between teeth. Electric toothbrushes are divided into two types: plug-in and battery-driven.

[0003] For example, the prior art CN213372669U proposes an electric toothbrush set with a disinfection function, which includes a toothbrush body and a sterilization device, and the toothbrush body and the sterilization device are detachably connected; the sterilization device is provided with a storage slot; the toothbrush set uses a sterilization lamp to irradiate the toothbrush to achieve the sterilization function of the toothbrush.
