Abstract

The utility model relates to an electric toothbrush which comprises a toothbrush cover, and a transformer, an accumulator, a direct current motor and a rectifying filtering voltage-regulating circuit which are arranged in a toothbrush handle, and a rechargeable plug. A brush head is sheathed outside a motor shaft, and is arranged in a toothbrush bracket. The motor shaft is supported by a bearing sleeve. The toothbrush bracket is connected with the front end of the toothbrush handle inside, and is fixed by a connecting nut. The exterior of a shell of the toothbrush handle is provided with a bidirectional variable-resistance switch which controls the positive rotation and the reverse rotation of the direct current motor. The positive rotation or the reverse rotation of the brush head are driven by the direct current motor. Bristles on the brush head vertically (up and down) and thoroughly clean teeth. The utility model has the advantages of labor saving, time saving, good effect and high safety, the goals of cleaning oral cavities and teeth are obtained, and simultaneously the utility model has the function of gum massage. The brush head is easy to assemble and disassemble, and is convenient for replacement.

Description

Electric toothbrush

This utility model relates to a kind of burnisher that is used for tooth, oral cavity, specifically is meant a kind of electric toothbrush.

At present the toothbrush that uses is traditional manually plug-type, is to be made of brush that has bristle and brush holder.This traditional toothbrush working costs effort, not thorough to tooth and oral cavity cleaning, improper use sometimes overexerts and causes the gingiva damage, and is bigger to the destructiveness of gingiva.

The purpose of this utility model provides a kind of time saving and energy saving, and is thoroughly clean to tooth and oral cavity cleaning, gingiva is had massage effect, electric toothbrush safe in utilization.

The purpose of this utility model is achieved in that

A kind of electric toothbrush, include the outer transformator that is enclosed within the toothbrush cover of toothbrush handle front end and is located at toothbrush handle inside, accumulator, dc motor and rectification filtering voltage stabilizing circuit, it is characterized in that an end overcoat of motor shaft has the brush of bristle, brush places in the toothbrush holder, the motor shaft at brush two ends is supported by the bearing holder (housing, cover) on the toothbrush holder, connect the toothbrush handle front end in one end of toothbrush holder, and fix by coupling nut, in motor shaft passes through toothbrush handle, outside place is provided with sealing ring, be provided with the control dc motor just changes in the outside of toothbrush handle housing, the two-way change resistance of counter-rotating is opened, and its rear end also is provided with the charging latch.

Above-mentioned brush is a hexagon, is provided with bristle on its prismatic outside, and the inside of hexagon brush and an end are that the motor shaft of hexagon socket-connects.

In addition, toothbrush holder one end can be with the toothbrush handle front end mode of joining: the toothbrush handle Front-end Design becomes hexagon, toothbrush holder one end inner chamber correspondingly is designed to the hexagon cavity, with the socket of toothbrush handle front end corresponding configuration, fixes by the overcoat coupling nut then.

Owing to adopt such scheme, by driven by motor brush forward or reverse, the bristle on the brush vertical (up and down) thoroughly cleans tooth, and is time saving and energy saving, reaches the purpose to oral cavity, cleaning of teeth, effective, safe in utilization, simultaneously gingiva had massage effect.Between brush, motor shaft and the toothbrush holder, all be provided with sealing device between motor shaft and the toothbrush handle, water resistance is good, and brush is easy to loading and unloading, is convenient to change.

Below in conjunction with accompanying drawing embodiment of the present utility model is described further.

Fig. 1 is a front view of the present utility model.

Fig. 2 is that A-A of Fig. 1 is to profile.

Fig. 3 is circuit theory diagrams of the present utility model.

The front end socket toothbrush cover 1 of toothbrush handle 8, toothbrush cover 1 can be filled with water and play the effect of tooth mug, each electric elements in transformator 12, accumulator 16, dc motor 13 and the rectification filtering voltage stabilizing circuit 10 are fixed on the fixing head 14 of toothbrush handle inside, the two-way change resistance switch 9 that control dc motor 13 is just changeing, reverses and stopping to be located at the outside of toothbrush handle 8 housings, and the rear end of toothbrush handle 8 also is provided with charging latch 11.One end of motor shaft 15 is a hexagon, with brush 5 phase configuration that are all the hexagon cavity, bristle 4 is fixed on the outer surface of hexagon brush 5, brush 5 places in the toothbrush holder 2, the motor shaft at brush 5 two ends is by 3 supportings of the bearing holder (housing, cover) on the toothbrush holder 2, bearing holder (housing, cover) 3 also has the effect of dash, one end of toothbrush holder 2 is that toothbrush handle 8 Front-end Design become hexagon with the mode of joining of toothbrush handle 8 front ends, toothbrush holder 2 one end inner chambers correspondingly are designed to the hexagon cavity, with toothbrush handle 8 front end corresponding configuration sockets, fixing by overcoat coupling nut 6 then.Pass through in the toothbrush handle 8 at motor shaft 15.Outside place is provided with sealing ring 7, enters toothbrush handle inside to stop water or dust.

Operation principle (circuit theory diagrams are with reference to Fig. 3): the latch that at first will charge is released the toothbrush handle housing and is inserted on the socket of power supply 220V, electric current is through the transformator transformation, charge a battery through rectification circuit then, and have display lamp to determine whether accumulator is full of electricity, be full of behind the electricity and transfer to socket to push back in the toothbrush handle housing power supply pin.Accumulator is given the dc motor supply power, two-way change resistance on-off control motor forward or reverse, and the electric drive axle drive brush of motor rotates up and down brushes teeth.
