Description

A kind of modified model electric toothbrush

Technical field

This utility model relates to daily life field, is specifically related to a kind of modified model electric toothbrush.

Background technology

Brushing teeth is that people guarantee a requisite activity in the life of dental health, and incorrect teeth brushing way not only is difficult to play and takes care of one's teeth and reject effect such as tartar, can produce infringement to a certain degree to tooth and gingiva on the contrary; The structure of its toothbrush is bigger to the influence of teeth brushing way, and as brush for toothbrushing, toothbrush is in order to cooperate tooth contour and surface microstructure; The quality that assurance is brushed teeth, the profile of its structure and brush is unchangeable, but along with development of science and technology; Occurred electric toothbrush on the market, mainly be divided into two kinds of plug-in source formula and battery-operated formulas, wherein battery-operated formula because of easy to use use more extensive; Its structure mainly comprises brush holder, brush holder support and brush, and brush holder is generally hollow structure, in the two switch of battery, motor and electrical connection is housed; Motion mode according to brush generally is divided into three kinds of electric toothbrushes; First kind is the electric toothbrush that brush is done straight reciprocating motion, and promptly brush is brushed teeth with the mode that on the brush length direction, back and forth shakes, and bristle is along with brush is laterally brushed moving along the vertical direction of teeth space and dental surface organizational structure at dental surface; This kind electric toothbrush principle is simple; Use also more convenient, but its cleaning tartar not thorough, also can cause certain damage to tooth and gingiva; Second kind is brush around the electric toothbrush of rotating with the vertical axle of the output shaft of motor; Be that this kind toothbrush is when brushing teeth; It is moving that bristle is made revolving brush at dental surface, and the friction effect of this mode is stronger, and is better to the cleaning effect of dental surface; But the tartar cleaning effect to teeth space and gingiva place is relatively poor, and tooth and gingiva are all had very big wear damage; The third is the electric toothbrush of comprehensive above-mentioned two kinds of principles and mode, combines the advantage of above-mentioned two kinds of electric toothbrushes, also combines the shortcoming of the two simultaneously, thus for better cleaning with take care of one's teeth, more than three kinds of electric toothbrushes all should not adopt.Brush teeth for ease, drive motors generally all places in the containing cavity of brush holder formation, again through the actuator drives brushhead motion; Actuating device is through the hollow bulb of brush holder support; So that brush holder support is generally is thicker, clumsy, straight plate and harder form, during use, can not suitable flexural deformation according to stressed and necessary situation; Clumsy profile makes it grip underaction conveniently, and it is all relatively poor at aspects such as motility, comfort and aesthetic measures to compare common toothbrushes.

The utility model content

The purpose of this utility model is to provide a kind of modified model electric toothbrush, and the direction of motion of bristle meets people's daily tooth-brushing habit, can effectively take care of one's teeth and gingiva, and the cleaning tartar is effective; And brush holder can be arranged to the shape of camber or other ergonomic, uses more comfortable.

In order to achieve the above object, the technical scheme of this utility model is:

A kind of modified model electric toothbrush; Comprise brush holder, brush holder support, brush, battery, two-way switch and motor; The two ends of above-mentioned brush holder support are installed above-mentioned brush holder and above-mentioned motor respectively, and the output shaft of this motor links together along the length direction setting of brush holder and with above-mentioned brush, is laid with bristle on the co-axial side face of the output shaft of above-mentioned brush and above-mentioned motor; Above-mentioned battery places in the inner containing cavity of above-mentioned brush holder; Above-mentioned two-way switch is arranged on the above-mentioned brush holder, is electrically connected between above-mentioned battery and this two-way switch, and above-mentioned motor is electrically connected with above-mentioned two-way switch through the lead that is passed by the inner cavity of above-mentioned brush holder support.
