Electric toothbrush

Abstract

An electric tooth-brush is composed of an electric driver and a tooth-brush consisting of brush head and handle. Said electric driver consists of electric drive mechanism and swinging mechanism which is composed of swinging connection part and supporter assemblage. Under the action of electric driver, the handle linked with said swinging connection part magnetically can swing back and forth.

Description

Technical field [0001] The invention relates to an electric toothbrush. Background technique [0002] Many electric toothbrushes have been developed for many years in the U.S. S. Patent Nos. 5,070,567, 5,186,627, 5,274,870, 5,341,534, 5,378,153, 5,732,433 disclose these devices. The existing electric toothbrush is composed of a brush head, a brush handle and a drive mechanism in the brush handle driven by a motor. The drive mechanism driven by the motor in the brush handle is well-known and widely used. In the known technology, there are various mechanical and mechanical connection devices including gears, which are used to convert the rotational movement of the motor into a brush head. However, these machines have complex structures and are not very reliable. Especially, special toothbrushes with complex structures must be used. The internal structure of the head brush head is complex and expensive. Summary of the invention [0003] The purpose of the present invention is to ov...
