Abstract

The technical scheme provided by the invention is to provide an electric toothbrush. The structure is as follows: the electric toothbrush comprises an outer shell, a brush head and a stretching device, wherein the outer shell is internally provided with a driving motor; the output end of the driving motor is provided with an eccentric shaft; and the brush head is connected with the eccentric shaft through the stretching device. The operation mode of the electric toothbrush is firstly different from the operation mode such as rotation or vibration of the brush head in the prior art, the operation mode that the brush head stretches back and forth is closer to the using habit of people, and also an ideal cleaning effect can be achieved; and because a gear structure which is normally used in the traditional electric toothbrush is not used, noise in using can be lowered greatly, and the electric toothbrush is comfortable to use.

Description

Electric toothbrush

Technical field:

This utility model relates to a kind of electric toothbrush.

Background technology:

In prior art, electric toothbrush is mainly divided into number of different types according to operation principle, such as some realizes cleaning of teeth by the rotation of brush, some realizes cleaning of teeth by the vibrations of brush, but no matter be which kind of type, the existing electric toothbrush defect that ubiquity noise is large in actual use, and the working method of these electric toothbrush heads is different from the teeth brushing way that people compare custom, not too be accustomed to during use, by the impact of tooth-brushing habit, use and not too coordinate.

Utility model content:

For solving above-mentioned technical problem, this utility model provides a kind of noise little, more meets the electric toothbrush of ordinary person's use habit.

The technical solution of the utility model is, provide a kind of electric toothbrush with following structure, it comprises shell and brush, is provided with drive motors in shell, and it also comprises stretching device; The outfan of drive motors is provided with eccentric shaft, and brush drawn device is connected with eccentric shaft; Described stretching device comprises swing component, connector and pull bar, swing component installation free to rotate in the enclosure, the side of swing component is provided with the breach coordinated for eccentric shaft, the end of eccentric shaft reaches in breach, the upper surface of swing component is provided with eccentric swing axle, connector is hinged with swing eccentric shaft, and pull bar is connected with connector; The afterbody of described brush is provided with jack, brush and pull bar grafting; Be provided with guide in described shell, guide is enclosed within pull bar; Sealing member is provided with between described brush and shell.

After adopting said structure, this utility model has the following advantages:

First the working method that brush of the prior art rotates or vibrates is different from, brush is the use habit that the working method of stretching back and forth more presses close to people, also just more preferably cleaning effect can be reached, owing to not using gear structure conventional in conventional power toothbrush, significantly can reduce noise during use, more comfortable during use.The Main Function of the seal is that the Shi Youshui that prevents from brushing teeth flows in shell, thus causes the damage of motor and control circuit.

Wherein, described sealing member is dustproof silica gel cover.

Wherein, be provided with bearing between swing component and shell, swing component is installed on bearing in the enclosure through back shaft.This structure ensures that swing component can swing smoothly.

Fig. 2 is another partial structurtes schematic diagram of this utility model electric toothbrush;

Fig. 3 is this utility model electric toothbrush overall structure schematic diagram;

Fig. 4 is the another partial structurtes schematic diagram of this utility model electric toothbrush.

Detailed description of the invention:

Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.

As shown in Figure 1, Figure 2, Figure 3, Figure 4, this utility model electric toothbrush, it comprises shell 1 and brush 2, and brush 2 is made up of the end and bar portion of being with bristle, is provided with drive motors 3 in shell 1.

Special feature of the present utility model is: it also comprises stretching device; The joint of the outfan mounting strap eccentric shaft 4 of drive motors 3, brush 2 drawn device is connected with eccentric shaft 4.

Wherein the concrete structure of stretching device is: comprise swing component 5, connector 6 and pull bar 7, laterally zygomorphic pair of bearings 12 is provided with between swing component 5 and shell 1, installing rack 1.1 is also provided with in shell 1, bearing 12 is arranged on the bolster 13 on swing component 5, then, bearing 12 is arranged on the installing rack 1.1 in shell 1, like this, swing component 5 just freely can rotate in shell 1, the breach 8 coordinated for eccentric shaft 4 is provided with in the side of swing component 5, breach 8 and back shaft 13 are located along the same line, the end of eccentric shaft 4 reaches in breach 8, eccentric shaft 4 is driven to rotate when drive motors 3 rotates, eccentric shaft 4 stirs swing component 5 reciprocally swinging in breach 8, also eccentric swing axle 9 is provided with in the upper surface of swing component 5, connector 6 is hinged with swing eccentric shaft 9, the jack that connector 6 coordinates with eccentric swing axle 9 is elongated hole structure, this can be avoided eccentric swing axle 9 pairs of connectors 6 to apply horizontal force, such connector 6 is just only subject to longitudinal force, stability is better, the swing that swing component 5 swings can be with before and after follower link 6 and back and forth be twitched back and forth, lateral displacement can not be there is, then, pull bar 7 is connected with connector 6, so just achieve function flexible back and forth.Just can brush teeth after brush 2 is connected with pull bar 7, and the afterbody of described brush 2 is provided with jack 2.1, brush 2 and pull bar 7 grafting, both are fixed by friction tight plug-in mounting mode, relatively simple for structure, are also convenient to brush 2 dismounting.

For improving mobile accuracy and the reliability of brush 2, in shell 1, be provided with guide 10, guide 10 is enclosed within pull bar 7, plays guiding function to pull bar 7, certainly, also needs to be provided with necessary sealing member and carry out encapsulation process between guide 10 and pull bar 7.

Because electric toothbrush often contacts with water when brushing teeth, for preventing water stain entering in shell 1 from causing damage to drive motors 3, between brush 2 and shell 1, be provided with sealing member 11.The seal 11 is preferably dustproof silica gel cover.
