Description
Technical field
This utility model relates to a kind of electric toothbrush, relates in particular to a kind of rotary electric toothbrush.
Background technology
Toothbrush is the articles for daily use of people's indispensability as the instrument that keeps oral hygiene.Traditional toothbrush mostly is the manual toothbrush of one side fasten bristles, relatively effort.The appearance of electric toothbrush has made things convenient for people's life, and it is simple and easy to usefulness, the skill that allows the people grasp easily to brush teeth.
General brush-head structure of electric toothbrush in the market and common manual toothbrush are basic identical, single face has bristle head big, the width of cloth of brush up and down of toothbrush brush finish is very little, because the tooth teeth space caves inward and is along the vertical direction, be difficult for during with the horizontal brush of the toothbrush of this structure the residue in the teeth space is removed totally, easily make odontoseisis, unhealthful, easily run into dental bed because of the distance that moves up and down is short and erect when brushing, very inconvenient.Therefore, though use electric toothbrush more laborsaving, it takes laterally back and forth rotational structure, and lacks the mechanism in protection oral cavity, uses not very good.
Chinese patent literature CN 2836750Y discloses " a kind of rotary electric toothbrush ", it comprises motor, power supply, brush, handle, motor connects switch, motor is the complete cycle rotational structure, motor connects brush, handle connects protective cover, and jagged on the protective cover, brush stretches out from the breach on the protective cover.This electric toothbrush; because brush can rotate; and protective cover protection gingiva is arranged; can in the short time, clean down tooth; but the structure that its brush stretches out from the breach of protective cover one side inconvenience is changing brush head more, makes that on the other hand toothbrush head is bigger, when brushing teeth; toothbrush bristle can't brush side molar and wisdom teeth, can cause side molar and wisdom teeth pathological changes for a long time in the past.
Chinese patent literature CN 2912558Y discloses a kind of " 360 ° of rotating electric toothbrush "; it is provided with power supply, motor and decelerator in brush holder; motor is connected with power supply; its connecting line is provided with switch; the power output shaft connection reducer of motor; the output shaft of decelerator connects drive link; drive link passes brush holder and stretches out the brush holder front end; the end of drive link is connected with cylindrical brush; also be provided with the brush of taper at the cylindrical brush cephalic par; be provided with bristle around the brush, at brush arranged outside over cap.The electric toothbrush of this structure, can go deep into oral cavity cleaning inside the most inboard side molar and wisdom teeth, but because toothpaste is to be coated in the bristle outside in use, can only make on a part of bristle toothpaste is arranged, when the brush rotation is used, can not guarantee in the whole process of brushing teeth and each position of tooth all contacts toothpaste, and long trace pass the not only inconvenient user of structure that brush holder stretches out the brush holder front end and holds also and rupture from trace easily.
Chinese patent literature CN 2134174Y discloses a kind of " rotary toothbrush "; this rotary toothbrush is that motor is connected with brush by axle; distributing on brush bristle in a row and toothpaste in a row portals, and protective shaft jacket and semicircle toothbrush overcoat are equipped with in axle and brush place, are full of toothpaste in the brush endoporus.The description of using for toothbrush in the description of this patent documentation is: bristle contacts with tooth, and under action of centrifugal force, toothpaste portals from toothpaste and is thrown out of.But common toothpaste is solid-state, there is no the device of squeezing toothpaste in its description and accompanying drawing, and toothpaste is difficult to come out from toothpaste portals, and toothpaste stops up toothpaste easily and portal, and not only wastes toothpaste but also be inconvenient to use and clean.
