Description
Technical field
This utility model relates to power-actuated tooth-cleaning device, specifically, relates to a kind of electric toothbrush.
Background technology
For making tooth can obtain more ideal cleaning effect, people design electric toothbrush.Common electric toothbrush at present can obtain good cleaning teeth effect basically, but its drive mechanism complexity, manufacturing procedure is many, the cost height, drive mechanism such as Chinese patent CN1463684A disclosed " electric toothbrush " comprises an elementary drive mechanism and a secondary drive mechanism, motor (motor) drives a motor output element and rotates around the axle center of motor line, elementary drive mechanism links to each other with the motor output element, and rotatablely moving of motor output element changed into elementary mean speed, by the reciprocal rotary oscillation of elementary pendulum angle operation; Secondary drive mechanism links to each other with elementary drive mechanism, and reciprocal rotary oscillation is passed to secondary drive mechanism from elementary drive mechanism, forms around secondary drive mechanism output axial line, with secondary mean speed, by the reciprocal rotary oscillation of secondary pendulum angle operation; Secondary drive mechanism output axial line and motor output shaft heart line parallel; Secondary drive mechanism drives an output block, with secondary mean speed, by secondary pendulum angle, around the reciprocal rotary oscillation of secondary drive mechanism output axial line operation; Secondary drive mechanism can comprise one first gear member and one second gear member, the first gear member can comprise a fan-shaped ring gear and link to each other with elementary drive mechanism, the second gear member can comprise a pinion, is driven by the first gear member; Output block can comprise a detachable head toothbrushes of changing.
Summary of the invention
The purpose of this utility model provides a kind of electric toothbrush simple and compact for structure.The technical scheme that adopts is as follows:
A kind of electric toothbrush comprises brush holder, brush, and is located at the intravital power supply in brush holder chamber, motor and drive mechanism, and wherein brush and drive mechanism are in transmission connection, and it is characterized in that: brush is rotatable to be installed on the brush holder, and the brush pedestal is provided with a rectangular groove vertically; Drive mechanism comprises that the driving wheel that is fixed on the motor rotary shaft and middle part are fixed on drive link on the brush holder by elastomeric element, and driving wheel is provided with a slot near an end off-centre of brush, and the two ends of drive link place above-mentioned rectangular groove and slot respectively.
Described brush is installed in the brush holder front end by axle and axle sleeve, and its axis and axle sleeve are separately fixed on brush and the brush holder, also can be separately fixed on brush holder and the brush.
Described elastomeric element can be the sealing ring of being made by elastomeric material, sealing ring outer rim and brush holder cavity wall are tightly connected, the sealing ring center is provided with the through hole with the drive link coupling, drive link can pass this through hole and be fixed on the sealing ring, and sealing encloses the effect of sealing brush holder cavity and fixed conveyor bar.
Described drive link places an end of rectangular groove to be spherical, makes drive link more flexible with cooperating of rectangular groove, and reduces wearing and tearing.
Brush of the present utility model is made the rotation reciprocally swinging around its rotating shaft under the effect of power supply, motor and drive mechanism, can effectively remove on the tooth and teeth space in residue, and can protect gingiva and oral cavity injury-free; This utility model is simple and compact for structure, and part is few, and cost is lower, and the transmission efficiency height, and noise is little; Brush detachably cleans, changes, the toothbrush long service life.
Description of drawings
Fig. 1 is the structural representation of this utility model one preferred embodiment;
Fig. 2 is the structure of driving wheel of preferred embodiment shown in Figure 1 and the sketch map of position;
