Abstract

The utility model relates to an electric toothbrush. The electric toothbrush is little in noise and suitable for using habits of ordinary people. The electric toothbrush structurally comprises an outer shell and a brush head, wherein a driving motor is arranged in the outer shell. The electric toothbrush further comprises a stretching device. An eccentric shaft is arranged at an output end of the driving motor, and the brush head is connected with the eccentric shaft through the stretching device. Different from a working mode of rotating or vibrating of a brush head in the prior art, the brush head is in a working mode of stretching out and drawing back in a back-and-forth mode and is adapted to the using habits of people, and thus ideal cleaning effects can be achieved; and due to the fact that a gear structure frequently used in a traditional electric toothbrush is not used, noise in use can be greatly reduced, and people feel comfortable when the electric toothbrush is used.

Description

Electric toothbrush

Technical field:

This utility model relates to a kind of electric toothbrush.

Background technology:

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

The 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, a kind of electric toothbrush with following structure is provided, and 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.

After adopting said structure, the utlity model has following advantage:

At first be different from the working method that brush of the prior art rotates or vibrates, the use habit that brush is more pressed close to people for flexible back and forth working method, also just can reach more preferably cleaning effect, owing to not using gear structure commonly used in conventional power toothbrush, can significantly reduce the noise when using, more comfortable during use.

Concrete, described stretching device comprises swing component, connector and pull bar, swing component installation free to rotate in the enclosure, one side of swing component is provided with the breach that coordinates for eccentric shaft, the end of eccentric shaft reaches in breach, the upper surface of swing component is provided with the eccentric swing axle, and connector is hinged with the swing eccentric shaft, and pull bar is connected with connector.

Wherein, the afterbody of described brush is provided with jack, and brush and pull bar are pegged graft.

Wherein, be provided with guide in described shell, guide is enclosed within on pull bar.

Wherein, be provided with sealing member between described brush and shell.The Main Function of the seal is that the Shi Youshui that prevents from brushing teeth flows in shell, thereby causes the damage of motor and control circuit.

Wherein, described sealing member is the dustproof silica gel cover.

Wherein, be provided with bearing between swing component and shell, swing component is on back shaft installation bearing in the enclosure.This structure guarantees 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.

The specific embodiment:

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, this utility model electric toothbrush, it comprises shell 1 and brush 2, brush 2 is provided with drive motors 3 by forming with the end of bristle and bar section 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 devices are connected with eccentric shaft 4.

wherein the concrete structure of stretching device is: comprise swing component 5, connector 6 and pull bar 7, be provided with laterally zygomorphic pair of bearings 12 between swing component 5 and shell 1, also be provided with installing rack 1.1 in shell 1, bearing 12 is arranged on bolster 13 on swing component 5, then, bearing 12 is arranged on installing rack 1.1 in shell 1, like this, swing component 5 just can freely rotate shell 1 is interior, a side at swing component 5 is provided with the breach 8 that coordinates for eccentric shaft 4, breach 8 is located along the same line with back shaft 13, the end of eccentric shaft 4 reaches in breach 8, drive motors 3 drives eccentric shaft 4 and rotates when rotating, eccentric shaft 4 is stirred swing component 5 reciprocally swingings in breach 8, upper surface at swing component 5 also is provided with eccentric swing axle 9, connector 6 is hinged with swing eccentric shaft 9, the jack that coordinates with eccentric swing axle 9 on connector 6 is the slotted hole structure, this can be avoided 9 pairs of connectors 6 of eccentric swing axle to apply horizontal force, connector 6 just only is subject to longitudinal force like this, stability is better, the swing that swing component 5 swings can drive the back and forth twitch back and forth of connector 6 front and back, lateral displacement can not occur, then, pull bar 7 is connected with connector 6, so just realized the function of stretching 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 is pegged graft with pull bar 7, and both fix by friction tight plug-in mounting mode, and are relatively simple for structure, also are convenient to brush 2 dismounting.

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

Because electric toothbrush when brushing teeth often contacts with water, for preventing that water stain to enter shell 1 interior to drive motors 3 injuries, be provided with sealing member 11 between brush 2 and shell 1.The seal 11 is preferably the dustproof silica gel cover.
