Description

Electric toothbrush

This utility model is a kind of for people toothbrushes for toothbrushing, particularly be a kind of electric toothbrush.

The toothbrush that people generally use now mostly is the toothbrush of vertical, and toothbrush is done transverse movement, unfavorable cleaning the teeth, not science when brushing teeth.

Electric toothbrush of disclosed ZL93236486.1 replaceable brush head now and ZL93209370.1 electric health-care toothbrush, the tooth brush for health protection of ZL92213188.0 rotating type electric etc. all are that the vertical of traditional form is the toothbrush of straight-bar type.People use inconvenience, and the structure more complicated.

The purpose of this utility model is to provide a kind of easy to use, labour-saving to turn the wushu electric toothbrush, and this toothbrush has changed traditional vertical Tooth-brush structure, and makes the motion that vertically rotates automatically of toothbrush bristle when brushing teeth, so that reach the tooth protection tooth-cleaning action.

The purpose of this utility model is to realize like this, electric toothbrush comprises brush, brush head frame, brush holder, motor, decelerator, battery are housed in the brush holder, brush is enclosed within on the brush head frame, and brush head frame is connected with decelerator by power transmission shaft, and this utility model has changed the straight-bar type toothbrush structure that comprises above-mentioned electric toothbrush, for reach convenient, laborsaving, tooth protection, purpose cleans the teeth, the brush holder of this toothbrush is and turns a shape, turn in motor is housed, motor shaft is connected with the brush head frame power transmission shaft is vertical by decelerator.

Decelerator of the present utility model adopts worm and gear, and to reach the deceleration Stabilization, this decelerator has improved the effect of motor resistive drag force simultaneously.

Be the protection oral cavity; this utility model is with the rotating commutation head that is half garden shape opening at the outer gusset of brush, and the commutation head can reduce the resistance of toothbrush, adjusts the direction of brushing teeth; make the bristle contact tooth on the brush and do not damage gingiva, the commutation head is fixed on the brush head frame with alignment pin.

This utility model is equipped with waterproof apron at the front end of brush holder, and waterproof apron is enclosed within protects motor in order to avoid make moist on the power transmission shaft.

The two-direction switch of control motor along backwards rotation is housed on the shell of brush holder, brush is turned clockwise when brushing tooth, be rotated counterclockwise during the brush lower teeth.

The lower end of brush handle shell is equipped with attaching plug, but also external power supply.

This utility model operation principle is that motor rotates, and by decelerator the rotating speed of reducing to per minute 600 commentaries on classics is at a high speed passed on the power transmission shaft, and drive brush head frame, brush vertically rotation are finished the action of brushing teeth.

Simple in structure, the flexible operation of this utility model, laborsaving, easy to use, also can be manual.Brush can be changed, and commutation head can be adjusted the direction of brushing teeth simultaneously, and the protection oral cavity makes bristle directly contact tooth and do not damage gingiva, improves brushing efficiency.Change wrong horizontal tooth-brushing habit, vertically brushing teeth automatically reaches tooth protection and cleans the teeth.Remove commutation this utility model and can make brush usefulness, scrub other vessel, reach one-object-many-purposes.

For further specifying electric toothbrush of the present utility model, embodiment is specifically described as follows with reference to accompanying drawing:

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

The garden cylindricality brush 2 that has bristle on every side is enclosed within on the brush head frame 3, brush 2 outer gussets are with the rotating commutation 1 that is half garden shape opening, commutation 1 is fixed on the brush head frame 3 by 6 alignment pins, brush head frame 3 is connected with decelerator 8 by power transmission shaft 6, decelerator 8, motor 9, battery 12 is contained in the brush holder 13 that has dividing plate and turns in the handle, front end suit waterproof apron 5 at power transmission shaft 6, power transmission shaft 6 is by bolster 7 supportings, be connected by worm type of reduction gearing 8 and motor shaft are vertical, on the shell that brush holder 13 turns two-direction switch 10 is housed, its lower end is equipped with attaching plug 11.
