Abstract

A double-end electric toothbrush comprises a toothbrush end, a toothbrush bar, and a toothbrush handle, and the toothbrush end consists of a round roller and a radial cylindrical surface toothbrush bristle of the round roller. The end of the toothbrush bar is a U-shaped end, and the toothbrush end is arranged between two sides of the inside of the U-shaped end; the toothbrush bar is hollow, and a transmitting wire in the toothbrush is connected with the toothbrush end; the toothbrush handle comprises a handle shell, an inside driving device, and a speed change gear, and the roller shaped toothbrush end can brush along the tooth space, improving the cleaning effect of brushing; the two toothbrush ends comfort the teeth by changing the distance of the ends by rotating a certain angle, thereby avoiding the injury of the gingival. Additionally, the mechanical spring is used as the power, which is not only saving the energy, but also good to environmental protection.

Description

Tow-head electric toothbrush

This utility model relates to the articles for daily use, is specially a kind of tow-head electric toothbrush.

Toothbrush is the requisite articles for use of people's daily life, and the most frequently used is the ordinary toothbrush of single brush.In order to improve brushing efficiency, had a kind of toothbrush of double end to come out afterwards, its brush is littler than the brush of common single head toothbrush, and the bristle of two brushes is relative, is connected with brush holder by two brush holder supports.Make two brushes place the both sides of tooth when brushing teeth.This toothbrush has following shortcoming: reach the purpose of the seam of brushing teeth owing to can not resemble when brushing teeth the single head toothbrush by rotating brush holder, and the space of directly moving is very little up and down, institute can only laterally brush teeth, effect is bad, cause damage gingiva when using toothbrush, and when the bristle deliquescing, can not brush teeth effectively.

The purpose of this utility model just provides a kind of can brushing teeth along seam, and can regulate the bristle spacing, the tow-head electric toothbrush that toothbrushing effect is good.

The technical solution of the utility model is: this utility model comprises successively brush, brush holder support, the brush holder that connects, and described brush is made up of circle roller and the radial bristle of its cylinder, respectively has one carefully spool at two axial ends of this circle roller; In the end of described brush holder support is the U-shaped head, the thin axle of described brush places between the inboard both sides of U-shaped head, brush axially with brush holder support in the same way, two brush holder supports are parallel and make the mouth of U-shaped head of two brushes relative, brush holder support is hollow, has a driving wire to connect the thin axle of brush within it; Described brush holder comprises handle shell and inner power set, change-speed gearing thereof, and the outfan axle of change-speed gearing links to each other with the driving wire of described two brushes respectively, and the input of change-speed gearing connects power set.

Described power set comprise battery that is positioned at handle shell rearmost end and the motor that is adjacent, and motor reel is connected with change-speed gearing.

Described power set are mechanical clockwork spring.

The U-shaped head of described brush holder support bends towards a side, the other end at brush holder support has a flange gear, at brush holder support upper edge circumference 3-5 pit arranged near the flange gear, two flange gears are meshed, the scrobicular ring that cooperates with brush holder support flange gear is arranged at brush holder and brush holder support link, also have a salient point corresponding with the brush holder support groove position, brush holder is the two halves fastening structure, and its buckling surface is the plane that two brush holder support centrages constitute.

The utility model has the advantages that: roller shape brush can be brushed teeth along teeth space, improves the cleaning effect of brushing teeth; Two brushes make its spacing change by turning an angle, it is comfortable to guarantee to brush teeth, and avoids damaging gingiva.In addition, as power, both energy savings was beneficial to environmental protection again with mechanical clockwork spring.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a cutaway view of the present utility model;

Fig. 2 is the vertical view of Fig. 1.

Referring to Fig. 1 and Fig. 2, this utility model comprises successively brush 1, brush holder support 2, the brush holder 3 that connects, and described brush 1 is made up of circle roller 11 and the radial bristle 12 of its cylinder, respectively has one carefully spools 13 at two axial ends of this circle roller 11; In the end of described brush holder support 2 is U-shaped head 21, and the thin axle 13 of described brush places between the U-shaped head 21 inboard both sides, brush 1 axially with brush holder support 2 in the same way, two brush holder supports 2 are parallel and make the mouth of U-shaped head 21 of two brushes 1 relative.Brush holder support 2 is hollow, has a driving wire to connect the thin axle 13 of brush within it; Described brush holder 3 comprises handle shell 31 and inner power set, change-speed gearing 32 thereof, and the outfan axle of change-speed gearing 32 links to each other with the driving wire 4 of described brush respectively, and the input of change-speed gearing 32 connects power set.

Described power set comprise battery 33 that is positioned at handle shell 31 rearmost ends and the motor 34 that is adjacent, and motor reel is connected with change-speed gearing 32.

Described power set are mechanical clockwork spring.

The U-shaped head 21 of described brush holder support bends towards a side, the other end at brush holder support 2 has a flange gear 22, at brush holder support 2 upper edge circumference 3-5 pit 23 arranged near flange gear 22, two flange gears 22 are meshed, with brush holder support 2 links the scrobicular ring 35 that cooperates with brush holder support flange gear is arranged at brush holder 3, also have a salient point 36 corresponding with the position of the pit 23 of brush holder support, brush holder 3 is the two halves fastening structure, and its buckling surface 37 is the plane that two brush holder support centrages constitute.Can make different pit 23 on the corresponding brush holder support of salient point in the brush holder 3 by rotating brush holder support 2, make two brush holder supports 2 rotating certain angle relatively synchronously, reach the purpose that changes two brush 1 spacings.
