Abstract
The utility model discloses a simple structure, two -way pivoted unipolar brush hair electric toothbrush simultaneously, including brush holder, brush hair, electronic mechanism, electronic mechanism hides in the brush holder, and electronic mechanism is gear motor, and gear connection gear motor is passed through in the brush hair pivot, and the brush hair pivot has the sleeve outward, and the sleeve passes through gear connection gear motor, and brush hair pivot and sleeve end axial fixity respectively have the brush hair, and it is rotatory simultaneously that two parts are separated into to the brush hair, opposite direction, and difficult clear position in removal toothbrush alright the clean tooth improves brush teeth efficiency and effect when brushing teeth.
Description
Technical field
This utility model relates to the electric toothbrush for cleaning teeth.
Background technology
Electric toothbrush is the instrument of a kind of cleaning teeth common in daily life, and existing electric toothbrush is made up of brush holder, motor, reducing gear rotating shaft and bristle, by the rotation of motor, bristle is rotated during startup.
Bristle rotation mode roughly has two kinds, a kind of be bristle be arranged on brush holder axis rotating shaft on realize bristle axial-rotation, another kind is that bristle is arranged on brush holder side direction and realizes side direction and rotate.The bristle of single direction rotation shows slightly scarce capacity at some position of cleaning, so people adopt two-way and close the reverse rotation making bristle be interrupted.Rotary electric toothbrush disclosed in CN2543499Y, its switch is that double-pole is two-way and close, and bristle can be made to carry out positive and negative rotation.
Electric tooth disclosed in CN201840541U is brushed with the brush holder of housing, two parallel side-by-side, and brush holder side is extended with bristle, drives two brush holder synchronous backwards to rotate and realize forward and reverse rotation of bristle by motor drive mechanism.CN104905887A discloses a kind of Dual-shaft electric toothbrush, comprise housing as handle adjacent with two, the brush that reversely rotates, brush comprises brush and brush axle, and brush axle is driven by the motor installed in the housing.Adopt twin shaft bristle to cause bristle volume excessive, when brushing teeth, oral cavity is uncomfortable, and equally with single shaft bristle shows slightly scarce capacity clearing up some position.
Summary of the invention
The purpose of this utility model is to provide a kind of simple structure, can the single shaft bristle electric toothbrush of simultaneously Double-directional rotary.
Electric toothbrush of the present utility model comprises brush holder, bristle, motor drive mechanism, motor drive mechanism is hidden in brush holder, motor drive mechanism is reducing motor, bristle rotating shaft connects reducing motor by gear, sleeve is had outside bristle rotating shaft, sleeve connects reducing motor by gear, and bristle rotating shaft and cover shaft end respectively axial restraint have bristle.
Preferably, sleeve is contrary with the direction of rotation of bristle rotating shaft.
Can there be disjunction in the centre position of above-mentioned bristle rotating shaft and sleeve, and the two ends of disjunction connect respectively by shaft coupling.The correspondence position that brush holder is positioned at the disjunction position of bristle rotating shaft and sleeve has disjunction, and the two ends of disjunction are by being fitting to connection.
There is bristle protective cover above-mentioned brush holder front end, this bristle protective cover has the axis hole of bristle rotating shaft.
Above-mentioned reducing motor is connected with control circuit, and control circuit controls the rotating speed of reducing motor and turns to.
This utility model simple structure, bristle is separated into two parts and rotates simultaneously, and direction is contrary, and moving toothbrush when brushing teeth just can more difficult clean position in cleaning teeth, improves brushing efficiency and effect.
Accompanying drawing explanation
Fig. 1 is a kind of embodiment outside drawing of this utility model.
Fig. 2 is A-A sectional view.
Detailed description of the invention
Electric toothbrush as shown in the figure comprises brush holder 1, motor drive mechanism is hidden in brush holder 1, motor drive mechanism comprises battery 2 and reducing motor 3, battery 2 is electrically connected with reducing motor 3, there is gear 4 the rotating shaft front end of reducing motor 3, gear 5 is connected with a joggle gear 4, and gear 5 is simultaneously as the driving wheel of bristle rotating shaft 9 and sleeve 10.
Bristle rotating shaft 9 end is connected with gear 7, and gear 7 is connected with a joggle gear 6, and gear 6 is connected with a joggle gear 5.Sleeve 10 is enclosed within outside bristle rotating shaft 9, and sleeve 10 end is connected with gear 8, and gear 8 is connected with a joggle gear 5.
Brush holder anterior 13 is fitting to connection with brush holder 1, has bristle rotating shaft 14 and sleeve 15 in brush holder front portion 13, and the end of bristle rotating shaft 14 and sleeve 15 respectively axial restraint has bristle 16,17.Bristle rotating shaft 14 connects bristle rotating shaft 9 by shaft coupling 12, and sleeve 15 connects sleeve 10 by shaft coupling 11.Thus, brush holder front portion 13, bristle rotating shaft 14 and become departing between sleeve 15 with corresponding component in brush holder and be connected, make bristle 16,17 need to change, meet toothbrush use after the requirement changed of timing.Having protective cover 18 outside bristle bristle 16,17, preventing bristle 16,17 from scrubbing other positions, oral cavity when brushing teeth, it guarantees the steady rotation of bristle rotating shaft 14 and sleeve 15 axis hole of bristle rotating shaft 14 in protective cover 18.
When starting reducing motor 3, because bristle rotating shaft 9 and the gear that connects between sleeve 10 from reducing motor 3 have the different of odd number and even numbers, bristle rotating shaft 9 is contrary with the direction of rotation of sleeve 10, make the direction of rotation of bristle 16,17 contrary, position not easy to clean in teeth space can be cleaned when brushing teeth, effectively preventing facing from causing dental groove because brushing teeth, meeting the professional requirement of vertically brushing teeth.
Reducing motor 3 also connects battery 2 and control knob 19 by control circuit, is controlled rotating speed and the direction of rotation of motor, make the bristle on turning cylinder 14 and sleeve 15 can change direction of rotation respectively, and control the rotary speed of bristle 16,17 by control knob 19.
