Description

Technical Field

[0001] The invention relates to the field of electric toothbrushes, in particular to an electric toothbrush with replaceable batteries. Background Art

[0002] The electric toothbrush generates high-frequency vibrations through the rapid rotation or vibration of the motor core, which instantly breaks down the toothpaste into fine foam and deeply cleans the gaps between teeth. At the same time, the vibration of the bristles can promote blood circulation in the oral cavity and massage the gum tissue. There are three ways for the brush head of an electric toothbrush to move: one is reciprocating linear motion, one is rotational motion, and there is also a set of electric toothbrushes with both types of brush heads. The bristles of the toothbrush head are made of soft plastic fibers, and the ends of the bristles are processed into spherical shapes, which will not damage the teeth and gums, and will not affect the brushing effect. Not only can it clean every tooth, but it also massages the gums.

[0003] The battery of an existing electric toothbrush cannot be removed. When the battery of an electric toothbrush is damaged and cannot work properly, most users can only buy a new electric toothbrush. Only a very small number of users have sufficient professional knowledge to replace the battery of an electric toothbrush with a damaged battery. This situation causes most users to have a high cost problem in terms of the use of electric toothbrushes. Therefore, it is necessary to improve the existing electric toothbrush.
