Description

A kind of electric toothbrush

This utility model relates to a kind of electric toothbrush that is used to brush teeth.

It is reported that existing electric toothbrush is of a great variety, as to wheeled electric toothbrush, vibration reciprocating motor toothbrush etc.But their ubiquities have weak points such as cost height, impracticable, inconvenient cleaning, therefore, are difficult to so far be accepted by people.

The purpose of this utility model is, provide a kind of reasonable in design, cost is low, practical, be easy to clean, health, easy to use, effective electric toothbrush.

Technical solution of the present utility model is that existing electric toothbrush is improved.Bristle damages intraoral meat in order to prevent to brush teeth, and keep toothbrush with after health, be provided with toothbrush backplate and toothbrush guard shield at the axis hole end of housing.

In order to improve the effect of brushing teeth, on the wall of housing, be provided with the forward and backward on and off switch.

For the ease of cleaning the inboard of tooth with water, be equipped with by what bristle constituted and be spherical toothbrush.

For the ease of using, in having been made, the forward and backward on and off switch is provided with the rotating annular on and off switch of conducting strip.

This utility model and background technology relatively because this utility model has been taked above-mentioned technical solution, therefore, had reasonable in design, cost is low, practical, be easy to cleaning, health, advantage such as easy to use, effective.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the Tooth-brush structure sketch map that this utility model is equipped with.

Describe a specific embodiment of the present utility model in detail below in conjunction with accompanying drawing,

Referring to Fig. 1, housing 6 is made up of three parts, and motor 12 is housed in the housing at middle part.In the groove of the outer wall of the housing at middle part, motor cathode conductive film 3 is housed, cathode conductive film 14 and in the rotating annular on and off switch 13 of conducting strip 4 is housed.Front end at the housing at middle part is the housing that has axis hole of undergauge by the front end that is threaded, and change-speed gearing 2 is housed in this housing, and change-speed gearing 2 is connected with toothbrush power transmission shaft 11 with motor shaft by gear.Be with sealing rubber ring 10 on the toothbrush power transmission shaft 11 outside being positioned at housing and be plugged with and be cylindric toothbrush 8, and be equipped with by what bristle constituted and be spherical toothbrush (see figure 2) by what bristle constituted.Front end at this housing is plugged with toothbrush backplate 9 and toothbrush guard shield 1.At the rear portion of the housing at middle part by the housing of anode electric-conductor 5 and battery cathode electric-conductor 15 is housed in being threaded.No. 5 batteries 7 of two joints are housed in housing.Anode electric-conductor 5 is copper sheets.Battery cathode electric-conductor 15 is circle springs.

During use, the toothbrush guard shield is taken off, then toothbrush is immersed in the water and take out, on toothbrush, coat toothpaste after taking out toothbrush, toothbrush is placed on the tooth after coating toothpaste, pull the forward and backward on and off switch simultaneously, control as required.Behind tooth after brushing, power cutoff takes off the toothbrush backplate and cleans.After the cleaning, toothbrush backplate and toothbrush guard shield are inserted on the housing again.
