Abstract

The utility model provides an electric dual-direction rotary toothbrush for people daily family life. The utility model is easy to operated and scientific used. The utility model is characteristic in that the inner of a brush handle is provided with a direct current small motor and a dry cell which are respectively connected with a two-way switch. When the user presses the two-way switch, the supply source is communicated, and the rotary shaft of a starting motor is rotated. When the two-way switch is moved upward and downwards, the rotary shaft of the motor is rotated to the positive direction and the reverse direction, drives and goes through a coupling shaft for transferring rotation motive power to a cylindric brush head, and then brush hair on the brush head does axial rotation to the positive direction and the reverse direction following the brush head.

Description

Electric dual-direction rotary toothbrush

This utility model relates to a kind of Family Day and uses the electric double-way rotary toothbrush.

The toothbrush that uses in the people family is made up of brush holder and bristle two parts now, and it has characteristics such as simple in structure, light and handy, convenient, durable.Use the method for this toothbrush to have two kinds: a kind of is correct method; Another kind is wrong method.Correct method is: pinch brush holder with hands, bristle pastes tooth root portion, with wrist power twisting brush holder, drives bristle and is scrubbed up and down along teeth space by tooth root portion.More time-consuming, the effort of this method, the child is difficult to correct grasp, and adult also few people brushes teeth with the method.Another kind of wrong method is: majority are when brushing teeth, and bristle is not to move up and down along teeth space, but transverse movement.This method for brushing teeth can not effectively be removed the dirt in the teeth space, stays dental caries hidden danger, and gums is also had very major injury, makes the gingiva bleeding gingival hemorrhage of first toothbrushing person.Brushing time is long more, and is big more to the infringement of gums and dental nerve system, is difficult to play the good effect of tooth protection of cleaning one's teeth, and this also is one of many reasons of civilized regional periodontal disease.

The purpose of this utility model is: allow people take correct easy suitable slot method for brushing teeth, the tooth protection that cleans one's teeth, prevention dental caries do not injure gums, reduce periodontal disease, both save time, laborsaving, are easy to grasp use again.

Operation principle of the present utility model is as follows: the handle bottom is an aneroid battery, and battery top is a small machine, and battery connects a two-way switch with motor, the rotation of control motor both forward and reverse directions.Electric machine rotational axis connects a major axis, is a cylindrical fine, soft fur toothbrush on the major axis top.When firing switch, motor just rotation gets up, and along with moving up and down of switch key, motor carries out the rotation of positive and negative two directions, also does the rotation of positive and negative two directions by the cylindrical brush at major axis drive toothbrush top.Since the positive and negative rotation of brush, the bristle on the brush just can be easily in the tooth inside and outside each position up and down, rotate to crown along slot from tooth root, clean dirt.

This utility model compared with prior art, have the use science, easy and simple to handle, save time, laborsaving, when contacting work with tooth, bristle firmly evenly, do not damage gums, and no matter old young, as long as after distinguishing direction of rotation, press the two-way switch button, can correctly grasp method for brushing teeth, reach the tooth protection that cleans one's teeth, the prevention dental caries takes place, and reduces the purpose of periodontal disease.

Below in conjunction with accompanying drawing in detail overall structure of the present utility model is described in detail.

Fig. 1 is an overall structure cutaway view of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model.

With reference to Fig. 1.The electric double-way rotary toothbrush be divided into can sleeve pipe brush holder, brush two parts of loading and unloading.The brush holder part: 1.5 volts or 3 volts of motors (2) that are fixed in the plastic brush handle (1), mate the battery (3) of an identical voltage, battery can also can load and unload from bottom thread from the handle loading and unloading of uncapping.The spring (4) that connects at battery positive and negative polarities place and two lines of drawing from motor (2) all link with two-way switch (5), make it be controlled the rotation that motor (2) is made positive and negative two directions.The top of electric machine rotational axis (6) is six prisms (7), above the cover one in six square casings (8).Brushhead portion: the cylindrical brush (12) of a semicircle plastics backplate (13) lining, its circumferential surface is a bristle.Brush (14) and major axis (11), (9) are one with casting, and (9) are six prisms.When brush, when brush holder two parts sleeve pipe connects, six prisms (7) of brush holder part and six prisms (9) of brushhead portion just together are enclosed within interior six square casings (8) lining.Interior six square casings (8) are both to connect to six prisms (7) and (9), transmission again.Like this; when electric machine rotational axis (6) rotates; driving six prisms (9) by sleeve pipe (8) rotates; six prisms (9) are all one with circular shaft (11); stablize axle sleeve (10) through two circles, just drive the brush (12) of casting on circular shaft (11), in the protection oral cavity; in the semicircle backplates of plastics (13) that when avoiding rotary toothbrush to brush teeth and other positions rub, rotation work gets up.

Preferably 1.5 volts in direct current generator (2), battery (3) is the aneroid battery that is complementary with it, brush body (toothbrush bottom, middle part, brushhead) is a plastic; Two circles are stablized preferably miniature bearing of axle sleeve (10), and brush holder and brush connect with the emboss pit method; Brushhead portion is made large, medium and small three the model toothbrushes that can change, not only health, but also can adapt to different human needs.

Claims

An electric double-way rotary toothbrush of being made up of small DC motor (2), aneroid battery (3), two-way switch (5), power transmission shaft (9), (11), brush (12), semicircle plastics backplate (13) is characterized in that:

(1) controls the rotation that electric machine rotational axis is made positive and negative both direction with two-way switch;

(2) brushhead portion connects, transmits the axle of motor power, is one with the brush casting;

(3) circumference one side of something of brush has a semicircle plastics backplate that maintains static;

(4) the same level of brush and electric machine rotational axis is done axially rotation;

(5) toothbrush top, promptly brushhead portion is the sleeve pipe mode to exchange the brush of large, medium and small three kinds of models of loading and unloading.
