Abstract

This vertically rotary head-exchange toothbrush is made by connecting a brush head, a brush body, soft drive steel wires and a DC motor in order. The joint of the brush head axle is aligned and connected with the interface of the drive axle of the brush body, thus the brush head is fixed on the brush body. If used, push the positive and negative switches forwards, the motor rotates along the tooth sucture by counter-clockwise, when push the positive and the negative switches backwards, the pole type brush head rotates in a reverse direction. The vertically rotary head-exchange toothbrush of this model utility is convenient and comfortable for use.

Description

Vertical rotating changes an electric toothbrush

Affiliated technical field:

This utility model is that the vertical rotating that a kind of toilet article of dental care product, especially bristle can enter gingival sulcus and diastema changes an electric toothbrush.

Background technology:

At present, everybody known electric toothbrush, shortcoming is many, can not take care of one's teeth, and is inconvenient to use, and these are one of reasons that cause oral disease.Vertical rotating changes an electric toothbrush and takes vertical height to revolve principle, can effectively remove facing, the dirt that each position of teeth space and tooth is adhered to.

Summary of the invention:

Can not deeply and carefully periodontal groove and dental surface be protected by the medical circle requirement in order to overcome existing electric toothbrush, this utility model is inventor's secular observation of process and thinking, has developed a kind of vertical rotating and has changed an electric toothbrush.This vertical rotating changes an electric toothbrush not only can change head toothbrushes, and can be positive and negative along the rotation of tooth extreme direction, thorough cleaning teeth, thus reduce the oral disease incidence rate.

The technical scheme that its technical problem that solves this utility model adopts is: it is to be linked in sequence by brush, brush body, transmission steel wire tightrope, direct current generator that vertical rotating changes an electric toothbrush.The power transmission shaft interface of the brush head axis joint being aimed at brush body connects, and brush figure just is fixed on the brush body.Work as the time spent, push the forward and backward switch forward open, along the teeth space rotation, bristle can enter gingival sulcus and diastema to motor, and soft comfortable massage gingiva by counterclockwise.When changing, to hold brush outside and draw, brush can take off, and reaches using to make things convenient for clear, clean comfortable purpose.

The beneficial effects of the utility model are: can reduce oral disease allow society and own benefited obtain keeping healthy in, clean periodontal groove and teeth space easily, simple in structure.

Description of drawings

Further specify below in conjunction with Figure of description:

Fig. 1 is a brush of the present utility model

Fig. 2 is a brush body of the present utility model

Among the figure: 1, pillar brush 2, brush half garden guard shield 3, brush head axis joint 4, power transmission shaft interface 5, transmission steel wire tightrope 6, direct current generator 7, forward and backward switch 8, brush butt joint card

The specific embodiment:

The brush head axis joint 3 of brush (Fig. 1) is aimed at the power transmission shaft interface 4 of brush body (Fig. 2), brush (Fig. 1) is connected with brush body (Fig. 2), brush butt joint card 8 docks with butt hole on the brush body (Fig. 2), pillar brush (Fig. 1) just is fixed on the brush body (Fig. 2), connect motor 6 by transmission steel wire tightrope 5, drive system is connected.When brushing teeth, push forward and backward switch 7 forward open, motor 6 drives transmission steel wire tightrope 5 and presses same direction rotation with pillar brush 1 by counterclockwise rotating up and down along teeth space.When forward and backward switch 7 being pushed into backward counter-rotating, pillar brush 1 is rotation round about just, circuit interruption in the time of in the middle of forward and backward switch 7 is pushed into.When changing, to hold brush outside and draw, brush can take off and change head again.
