Description

Electric tooth-brush

This utility model relates to a kind of improved electric toothbrush.

At present, the toothbrush overwhelming majority that we use in the daily life is common board-like manual toothbrush, brush teeth with board-like manual toothbrush, because the structural design of toothbrush own is unreasonable, firmly excessive, bigger to the dental bed stimulation, cause that easily dental bed is hemorrhage, firmly too small, then dirty thing is difficult to remove, influenced the effect of brushing teeth, and used electric toothbrush, though can solve some problems, but because present electric toothbrush structure more complicated, price is higher again, and toothbrush is bigger to the wearing and tearing of tooth, thereby applies few.

The purpose of this utility model just be to provide a kind of simple in structure, price is lower, can massage gingiva, eliminate the electric toothbrush of dirty thing.

This utility model mainly is made up of housing, motor, decelerator, head toothbrushes and backplate etc.Housing is cylindric, and battery is positioned on the intravital bottom of shell, and the tumbler switch and the motor that links to each other with switch that can control the motor rotating is equipped with at the housing middle part, the front-end of spindle of motor is equipped with decelerator, to reduce rotating speed, increase torsion, the decelerator front end is equipped with an output shaft.Output shaft pass the housing front end in unprecedentedly the pipe, join with head toothbrushes, the porous bristle is housed on the head toothbrushes, the backplate of one and half tubulars is equipped with in the head toothbrushes outside, backplate is fixed on the housing front end.When brushing teeth, water is put in the brush front portion, soak bristles, toothpaste is clamp-oned between two row's brush bristles, opens switch, and motor rotates, and by decelerator and output shaft, drives head toothbrushes and rotates, and again the brush head of rotating is pressed to tooth.In order to reach the thorough purpose that cleans the teeth, when brushing tooth, the toggle switch that should make progress just changes motor, and during the brush lower tooth, toggle switch makes the motor counter-rotating downwards.

This utility model is compared with existing electric toothbrush, has tooth dirt elimination factor height, comfortable taste, characteristics such as simple to operate, to the gingiva position can science massage, can effectively prevent the generation of various odontopathy, be a kind of desirable brushing tool.
