Abstract

The utility model relates to a powered toothbrush used for toothbrushing along the teeth. The utility model is installed with a motor in the cylindrical brush body. The toothbrush head is driven to spin along the teeth by changing the speed of the gear. So as to avoid hurting the oral cavity, a protective plate is installed at the front axis end of the brush body. The wall of the middle part of the brush body is installed with a clockwise and an anticlockwise rotary power switch which can be adjusted at will. In toothbrushing, the gingival will not be hurt, and left hanged food fregments and dental calculus in the slit between the teeth can be totally removed. At the same time, the fine and soft bristle on the brush head can do massage to the teethridge and accelerate the blood circulation and make the teeth more firm. The brush head can be taken off to clean and replace at any time. In order to forestall the water entering the machine core and damaging the inner parts, a waterproof seal ring is arranged between the transmission axis and the brush body connected holes. The utility model adopts the fully-closed induction charging system which is safe and convenient to charge the battery.

Description

A kind of along the tooth electric toothbrush

(1) technical field:

This utility model relates to a kind of electric toothbrush that suitable tooth is brushed teeth that is used for.

(2) background technology:

Existing electric toothbrush is of a great variety, as to wheeled electric toothbrush, vibration reciprocating motor toothbrush, flush-type toothbrush, massage type electric toothbrush etc., their ubiquities have weak points such as cost height, fragile, the inconvenient cleaning of movement water inlet, are difficult to so far be accepted by people.

(3) summary of the invention:

This utility model provides that a kind of cost is low, long service life, be beneficial to health care, be easy to clean, the suitable tooth electric toothbrush of hygienic and convenient, the technical scheme that adopts is: this utility model is to be made of parts such as backplate, brush, power transmission shaft, change-speed gearing, brush body, motor, switch, interface circle, battery, tailstock, coil, sealing ring and display lamps, column type brush body front end is equipped with the brush backplate, can prevent to brush the wound chamber.Motor and rotating on and off switch are equipped with in the brush body middle part, and charging indicator light is housed on the lower part wall.Before being contained in the intravital motor of brush the motor locating shim is housed, change-speed gearing is housed before the pad, the center power transmission shaft is housed on the change-speed gearing, removable round head toothbrushes is housed before the power transmission shaft.Damage the movement parts in the brush body for anti-sealing advances, between power transmission shaft and brush body string hole, waterproof grommet is housed.The interface circle is equipped with in the brush body lower end, and tailstock is housed on it, be equipped with in the tailstock rechargeable battery, the charging induction coil make charging system reach totally-enclosed waterproof effect.The rotating on and off switch is to be made of water proof rubber film, switching circuit plate, camshaft, electroconductive elastic sheet, X button, carriage, securing rod and switch body etc., the water proof rubber film is contained between brush body and switch body, which is provided with just change by point, close by the point and the counter-rotating by point.The switching circuit plate is contained on the switch body, and switch body is contained on the sidewall of brush body middle part.Camshaft, electroconductive elastic sheet, X button, carriage and securing rod are housed between switching circuit plate and switch body successively.The rotating on and off switch is the direction of rotation of conversion brush arbitrarily, make brush keep rotating and the Anti-dental injury gum to the crown direction, the plug of thoroughly removing between facing, teeth space is hung thing and tartar, and the continental quilt on the brush constantly changes the dental bed that rubs simultaneously, promote its blood circulation, make tooth firmer.

Owing to taked that above-mentioned technical solution, the beneficial effects of the utility model are that cost consumption is low, long service life, good health care effect, be easy to advantages such as cleaning, hygienic and convenient.
