Description

The comprehensive electronic device that cleans the teeth

[technical field]

This utility model relates to a kind of electric tooth-cleaning device, refers in particular to a kind of comprehensive electronic device that cleans the teeth that has with the corresponding shape brush of lower teeth on the oral cavity.

[background technology]

The structure of the structure of existing electric toothbrush and traditional toothbrush is roughly the same, all is brush holder one termination rectangle brush to be set, and brushes and is preset with a plurality of bristles on first face.In use, user still needs elder generation with the first-class toothpaste of toothbrush head, brushes the incisor of front then respectively, brushes canine tooth again and grinds one's teeth in sleep.There is following problem in existing electric toothbrush:

1. existing electric toothbrush is difficult to the tooth inner side brush is clean;

2. existing electric toothbrush dynamics is difficult to control, tooth is not cleaned down because dynamics is smaller probably, perhaps because overexerting gingiva is brushed out blood;

3. the user that has is not grasped the correct posture of brushing teeth, and is not brush when brushing teeth from root of the tooth toward corona, is difficult to the slit between tooth is cleaned down.

[summary of the invention]

For overcoming the deficiencies in the prior art part, this utility model provide a kind of can be disposable thoroughly with the back side and the clean comprehensive electronic device that cleans the teeth of interdental brush of front tooth, molar.

The technical scheme that this utility model technical solution problem adopts is: the comprehensive electronic device that cleans the teeth, the U-shaped brush holder that comprises a center drilling, these U-shaped brush holder tow sides are equipped with small one and large one two U-shaped metal rack respectively, described two U-shaped metal rack are all parallel with described U-shaped brush holder surface, the space between described two U-shaped metal rack and human body the upper jaw and the lower jaw tooth coupling; Be equipped with a plurality of compact arranged brush pieces on the described U-shaped metal rack, this brush piece center drilling, its both sides end face is respectively equipped with male joint and female joint, and the adjacent brush piece can be chimeric mutually, and described brush piece cylindrical is implanted with bristle, can rotate along described U-shaped metal rack; Described U-shaped brush holder cambered surface one side is equipped with a direct current reducing motor, the main shaft of this motor and a worm screw that is arranged in the described U-shaped brush holder central through hole are affixed, described large and small U-shaped metal rack in position is provided with the drive block of band external toothing, the external toothing of described drive block and described worm engaging, the both sides end face of described drive block is respectively equipped with male joint and female joint, and chimeric mutually with adjacent described brush piece.When DC speed-reducing drove the worm screw rotation, described drive block rotated under its external toothing effect thereupon, and drove the brush piece rotation on the whole U-shaped metal rack, and the bristle on the brush piece rotates thereupon, reaches the purpose of cleaning teeth.

Male joint preferred version on the described brush piece is in this brush piece one side end face three fan-shaped projections to be set, and described fan-shaped projection is symmetrically distributed along described brush piece central through hole.Female joint on the described brush piece is at this brush piece opposite side end face three sector grooves to be set, its size and described fan-shaped projection coupling.This joint design can make the brush piece adapt to the radian of U-shaped metal rack well, keeps good linking degree when this brush piece rotation.

Beneficial effect: this utility model can be coated in toothpaste on the bristle of brush piece, the energising back is by the rotation of these bristles, meeting be evenly coated in toothpaste on the tooth and brush teeth, such design can reach even, an amount of tow sides that are coated in tooth of toothpaste, each position of guaranteeing tooth comprises that teeth crevice is all cleaned down effectively, and can effectively avoid causing because overexerting gingival hemorrhage.
