Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric toothbrush technology, and in particular to a multifunctional electric toothbrush. Background Technology
[0002] Electric toothbrushes are a common oral care tool, widely used due to their ease of use and effective cleaning. They work by using a motor to rapidly rotate or vibrate the brush head, creating high-frequency vibrations that instantly break down toothpaste into fine foam for deep cleaning between teeth. Simultaneously, the bristle vibrations promote blood circulation in the mouth and massage the gums.
[0003] Electric toothbrushes often use sonic motors as a power source to drive the brush head and bristles to vibrate, thereby cleaning teeth. The rotor of a sonic motor vibrates near its equilibrium position, and its operating frequency is generally several hundred hertz, which is within the frequency range of normal human voice, hence the name sonic motor.
[0004] However, existing electric toothbrushes have limited functions, mostly only capable of vibrating while brushing, which cannot meet users' diverse oral care needs. Utility Model Content
