Abstract

The utility model relates to a dual-head electric toothbrush. The toothbrush is provided with two toothbrush heads respectively composed of a toothbrush rod and brush bristles arranged on the front end part of the toothbrush rod and a casing which is also used as a handle, an electric source and a micromotor connected with the electric source are arranged in the casing in sequence, and an output shaft of the micromotor is provided with a speed change mechanism used for driving the two toothbrush heads to rotate. When using the toothbrush to brush the teeth, the two toothbrush heads can simultaneously rotate along tooth gaps to easily clean the dirt among the tooth gaps, and the utility model enhances the efficiency of brushing the teeth and can not damage the gingiva.

Description

A kind of tow-head electric toothbrush

Affiliated field:

This utility model relates to a kind of apparatus of washing one's face and rinsing one's mouth that is used for cleaning teeth, especially relates to a kind of tow-head electric toothbrush.

Background technology:

Toothbrush is employed a kind of utensil that is used for cleaning teeth in people's daily life.Traditional toothbrush is to be made of brush holder and the bristle that is installed in the brush holder end.No matter the toothbrush that uses this kind structure is the direction along tooth when brushing teeth, and still brushes teeth along the tooth arrangement direction, all wants the action of armrest to control.But, because the brush holder support of this kind structure toothbrush is longer relatively, when the action of control bristle, particularly above-below direction moves comparatively difficulty, is not easy to do vertical action along the teeth space direction, also has the defective such as inhomogeneous and slow in one's movements of exerting oneself simultaneously, so the toothbrush of this kind structure is not suitable for vertically brushing teeth.

For this reason, swing type electric toothbrush or the revolving electric toothbrush of single head have appearred in market, but shuttle-type electric toothbrush is because of being subjected to the narrow restriction of its brush holder support structure, cause its amplitude of fluctuation too small, and can not reach the purpose of ideal cleaning teeth, and user the rigid phenomenon that collides of toothbrush and gingiva can occur when brushing teeth with this kind toothbrush; And the single head rotary electric toothbrush once can only be brushed the facing of a tooth, and can produce relatively large moment of torsion in rotation process, and thinner brush holder support is fractureed.

Summary of the invention:

The purpose of this utility model provides the tow-head electric toothbrush that a kind of mode of utilizing two-way rotation realizes scrubbing simultaneously two tooth faces.

The tow-head electric toothbrush that this utility model proposed, have two respectively by brush holder support and the brush that bristle constituted that is installed in this brush holder support leading section, and the housing of a double as handle, the micromachine that power supply is installed successively and is electrically connected with power supply in this housing, the output shaft of micromachine are provided with and are used to drive the gear that two brushes rotate.

Described housing is used to install the gear part and the sealing mutually of micromachine part is installed, and by the output shaft of micromachine two parts is connected, and this output shaft is provided with sealing member.Housing and offer the jack that two permission brush holder supports insert at an end of gear, brush can insert in the housing by this jack, and with the gear pivot bush unit.The end that described housing and brush join is provided with the baffle plate that extends to the bristle position.The outer surface of described housing is provided with on and off switch.

Described gear comprises driving gear on the output shaft that is directly installed on micromachine and the driven gear that is meshed with this driving gear, and, drive described brush holder support again by travelling gear and rotate by one group of reduction gearing and one group of travelling gear that this driven gear drives successively.

The tow-head electric toothbrush that this utility model proposed, employing be the structure that two brushes rotate simultaneously, two brushes are easy to the dirt removal between teeth crevice can be improved the efficient of brushing teeth simultaneously along the slots rotation when brushing teeth; Simultaneously, because the rotary power of brush comes from driven by power, and the rotatory force that produces is very even, and Shi Buhui causes damage to gingiva brushing teeth; In addition, the brush of this kind toothbrush can arbitrarily be changed, and is cost-saved and prolong its service life.

Description of drawings:

Accompanying drawing 1 is the surface structure sketch map of an embodiment of this utility model;

Accompanying drawing 2 is surface structure sketch maps of baffle plate among Fig. 1.

The specific embodiment:

Referring to Fig. 1, it provides the overall appearance structure of the embodiment of tow-head electric toothbrush that this utility model proposes.This tow-head electric toothbrush comprises brush holder support 1 and the housing 3 that has bristle 11, and is installed in power supply 4, micromachine 5 and gear 2 in the housing 3.

Housing 3 is used to install gear 2 parts and seals mutually with micromachine 5 parts are installed, and by the output shaft 51 of micromachine 5 two parts is connected, and this output shaft 51 is provided with sealing member, and water flows in the miniature motor 5 when brushing teeth to avoid

But housing 3 is used to install the part double as handle of micromachine 5, and the power supply of installing within it 4 can be made of battery, and is electrically connected with micromachine 5.Micromachine 5 has an output shaft 51, drives gear 2 by output shaft 51.Housing 3 and offer the jack 31 that two permission brush holder supports 1 insert at an end of gear 2, brush holder support 1 inserts in housings 3 back and makes its end and gear 2 pivot bush units by this jack 31, can be convenient for changing brush like this, with the saving use cost.The outer surface of housing 3 is provided with the on and off switch 6 that can make micromachine 5 and power supply 4 conductings or disconnection.

Gear 2 comprises driving gear 21 on the output shaft 51 that is directly installed on micromachine 5 and the driven gear 22 that is meshed with this driving gear 21, and the turning cylinder of driven gear 22 directly drives the input gear 23 of reduction gearing.Input gear 23 by with its reduction gearing that is meshed 24 after be connected with travelling gear 25 again, drive described two brush holder supports 1 again by travelling gear 25 and rotate.

When using this toothbrush, only need press on and off switch 6, drive brush holder support 1 rotation by gear 2, two brushes 2 rotate on the surface of two teeth simultaneously, make bristle 11 very easily that the cleaning of the dirt in the slot is clean under the situation that does not need artificially to exert oneself.

Fig. 2 is the surface structure sketch map of baffle plate 7 among Fig. 1.Housing 3 is provided with the baffle plate 7 that extends to bristle 11 positions with the end that bristle 11 joins.Baffle plate 7 is being provided with kink 71 with the corresponding position of bristle, and kink 71 can guarantee that bristle 11 intraoral its hetero-organization of protection when being rotated friction with tooth is injury-free.
