Abstract

The utility model relates to a novel toothbrush. The utility model is formed by assembling a handgrip, a brush body 6 and a small motor 3, wherein the handgrip is composed of a front barrel body 4 and a back barrel body 2 which are in coaxial and clamped sleeve joint. A dry cell is arranged in an inner cavity of the back barrel body 2, and the small motor 3 is arranged in an inner cavity of the front barrel body 4. A power supply wire end wafer of the small motor at the back end of the front barrel body 4 is contacted and connected with an electrode terminal at the front end head of the back barrel body 2. The small motor 3 drives a decelerating wheel train, and an output shaft 5 of the decelerating wheel train is assembled in a core hole at the front end surface of the front barrel body 4. Brush bristles which are radially perpendicular to an axial lead are planted and fixed on the cylindrical brush body 6 on a core column and are spliced and fixed on the output shaft 5 of the decelerating wheel train, and a shield 7 with a cylindric half side is sheathed, inserted and arranged on the front end head of the front barrel body 4.

Description

A kind of rotary tooth-brush

(1) technical field:

This utility model relates to a kind of toothbrush that the transmission brush body is arranged, particularly a kind of rotary tooth-brush of cleaning oral cavity tooth.

(2) background technology:

People generally are difficult to grasp the correct posture of brushing teeth when using ordinary toothbrush, and this not only is difficult to remove the filth in the tooth crack, and very easily injures gingiva, brushes bad tooth; Though the existing on the market at present good electroshock dynamic formula of toothbrushing effect toothbrush appearance, this toothbrush because structure is reasonable inadequately, are easy to break down and can only be used as ordinary toothbrush and use, its production cost is higher in addition, so affect its sales promotion.

(3) utility model content:

The purpose of this utility model is to provide a kind of rational in infrastructure, simple to the public, convenient use, the novel toothbrush that toothbrushing effect is good.This novel toothbrush is by handle, brush body and small size motor assemble, but described handle is the rear cylinder body and coaxial the clamping on the front end that is socketed in rear cylinder body of aneroid battery by endoluminal means, the preceding cylindrical shell that inner chamber is clamping small size motor constitutes, device pro-cylinder lumen follower head place, little electronic power supply the end of a thread contact touches with the electrode terminal of device at rear cylinder body inner chamber front end place, the wheel for inputting interlock of drive that is installing in the small size motor rotating shaft and deceleration train, the output shaft of deceleration train is fitted in the core hole of preceding cylindrical shell front end face, described brush body is that bristle is radially perpendicular to axial line, be packed in the cylinder on the stem stem side wall surface of brush body, peg graft on the termination of the output shaft that is packed in the deceleration train in core hole on the brush body stem stem tail end, for exempting to allow bristle scratch oral cavity inwall, add a front end especially and most be truncated into half of guard shield cylindraceous, on the front end of the tail end cover plug device pro-cylindrical shell of guard shield.

When using this novel toothbrush, need not to brandish toothbrush with hands, as long as being appeared the position, the bristle of this novel toothbrush stretches into the oral cavity sidewards, attach tooth, more preceding cylindrical shell is done relative rotation slightly with rear cylinder body, just can make the power supply the end of a thread contact of small size motor and the electrode terminal at rear cylinder body front end place touch conducting, small size motor rotates, drive the deceleration train, the rotating speed rotation that the deceleration back brush body promptly changes with per minute 60～120, bristle can be picked out the dirty thing in the tooth slot soon; Again preceding cylindrical shell and rear cylinder body are continued to do slightly relative rotation, each touches conducting with the electrode terminal of opposite polarity with small size motor power supply the end of a thread contact, make small size motor counter-rotating with regard to the right side, order about the brush body counter-rotating, thus realize to about row and the alternately brush of arranging tooth up and down gargle.Gargle brush with this novel toothbrush, the posture natural science is reasonable, need not through specialized training.The outer guard shield of brush body can be avoided bristle scratch oral cavity.Bristle slowly runs, and also can play massage effect to gingiva.Product structure is simple, production cost is low, easy assembling maintenance.

(4) description of drawings:

Fig. 1 is the structural representation of this novel toothbrush;

Fig. 2 is electrode conversion sketch map.

(5) specific embodiments:

This utility model can be with 1.5 volts No. 5 or No. 7 aneroid battery 1 power supply that is used as power.Rear cylinder body 2 can be made of duroplasts.The rear end women's head-ornaments of rear cylinder body 2 can be made into closed, and the electrode spring bottom surface of aneroid battery can directly be sat on the rear end inner bottom surface that is pressed in rear cylinder body 2.But on the internal face of cylindrical shell also direct-axis line symmetry offer two straight troughs, in order to installing the metallic conduction sheet of electrode, the metallic conduction sheet device of electrode is in straight trough, the location stage clip that can be used as aneroid battery again uses.Small size motor 3 acts in accordance with the intracavity posterior end position that axial line is installed on the preceding cylindrical shell made from duroplasts 4, the front end position of deceleration train wheel apparatus pro-cylindrical shell 4 inner chambers, before being fitted in, the output shaft 5 of deceleration train in the core hole of cylindrical shell 4 front end faces, must not produce axial motion.The stem stem of brush body 6 also can be made of duroplasts, and bristle is fixed on the stem stem sidewall along the dress of radially planting of the transverse section of brush body 6 stem stems.Be product attractive in appearance, guard shield 7 preferably uses transparent or colored non-toxic plastic making.For ease of the assembling maintenance, power supply the end of a thread contact of small size motor preferably is fitted in perpendicular to preceding cylindrical shell 4 axial lines, be installed on before on back Shaoshan face of insulating trip 8 at cylindrical shell 4 rear port places, and the electrode terminal of aneroid battery also preferably is fitted in perpendicular to rear cylinder body 2 axial lines, is installed on the front end face of insulating trip 9 at rear cylinder body 2 front port places, cutting ferrule tipping is gone forward, rear cylinder body, and power supply the end of a thread contact of small size motor just can be successfully touches with the electrode terminal of aneroid battery.

Claims

1, a kind of rotary tooth-brush, it is by handle, brush body 6 and small size motor 3 assemble, it is characterized in that: described handle is rear cylinder body 2 and coaxial clamping on the front end that is socketed in rear cylinder body 2 in battery 1 by endoluminal means, the preceding cylindrical shell 4 that inner chamber is clamping small size motor 3 constitutes, power supply the end of a thread contact of the small size motor 3 at device pro-cylindrical shell 4 intracavity posterior end places touches with the electrode terminal of device at rear cylinder body 2 front end places, the drive that is installing in small size motor 3 rotating shafts and the wheel for inputting interlock of deceleration train, the output shaft 5 of deceleration train is fitted in the core hole of preceding cylindrical shell 4 front end faces, described brush body 6 is that bristle is radially perpendicular to axial line and is packed in cylinder on the stem stem side wall surface, peg graft and be packed on output shaft 5 terminations of deceleration train in core hole on the brush body 6 stem stem tail ends, the tail end that front end most is truncated into half of guard shield cylindraceous 7 overlaps on the front end of plug device pro-cylindrical shell 4.
