The specific embodiment
See also Fig. 3, Fig. 4 and Fig. 5, among this utility model embodiment, electric toothbrush comprises battery cover 1, toothbrush shell 2, driving device for electric toothbrush, two head toothbrushes 13.Wherein, 2 water-tights of toothbrush shell and supporting role; Driving device for electric toothbrush is located in the toothbrush shell 2, and stretches out by two connecting axles 12 that toothbrush shell 2 is outer to be connected with two head toothbrushes 13 respectively simultaneously, drives two head toothbrushes 13 and carries out linear reciprocating motion.
Driving device for electric toothbrush includes a driving device support 3, motor 4, gear driven mechanism and cam drive mechanism, driving device support 3 wherein plays fixed support and modular power toothbrush drive part, and motor 4, gear driven mechanism and cam drive mechanism are installed in the driving device support 3; Wherein, gear driven mechanism comprises cone pinion 5, large bevel gear 6, roller gear A 6 ', intermediate cylindrical gear 8 and main roller gear 10, cam drive mechanism comprises the eccentric of being located at main roller gear 10 two sides, the slide block 11 that cooperates with eccentric and the connecting axle 12 of injection moulding on slide block 11, is specially:
At the fixing cone pinion 5 of motor 4 spindle ends, this cone pinion 5 is pressed into the spindle end of motor 4 for interference; Large bevel gear 6 rotational support mesh on driving device support 3 and with cone pinion 5; Roller gear A 6 ' and large bevel gear 6 coaxial synchronous rotations, and intermediate cylindrical gear 8 and main roller gear 10 mesh with roller gear A 6 ' successively; Intermediate cylindrical gear 8 one end rotational support on the driving device support 3, an end rotational support on a cross structure 9, the two ends of this cross structure 9 are fixed on the inwall of driving device support 3;
The two sides of main roller gear 10 respectively are provided with an eccentric, and two slide blocks 11 are slidingly matched by chute and eccentric respectively; Be injected with one respectively on two slide blocks 11 and be with the connecting axle 12 of screens, these two connecting axles 12 engage with a head toothbrushes 13 respectively, thereby realize the work that moves up and down of head toothbrushes when the turning cylinder motion of motor 4.In addition, the eccentric phase place of main roller gear 10 two sides can be identical, also can differ 180 degree; The material of connecting axle 7 and connecting axle 12 is preferably rustless steel, and the material of driving device support 3 is preferably plastics.
Above-mentioned electric toothbrush is when work, the turning cylinder high speed rotating of motor 4, by cone pinion 5 rotation is delivered to large bevel gear 6, large bevel gear 6 has played the dual function that reduces rotating speed and change rotation direction, by roller gear A 6 ', intermediate cylindrical gear 8 rotation is delivered to main roller gear 10 then, main roller gear 10 further reduces rotating speed so that the motion of toothbrush is converted to the acceptable operating rate; Because respectively there is an eccentric two sides of main roller gear 10, these two eccentrics are one with main roller gear 10 and respectively cooperate with a slide block 11, so when main roller gear 10 rotates, if two eccentric phase places are identical, then two eccentrics can drive corresponding slide block 11 and realize synchronous seesawing under the guide effect of driving device support 3, finally drive two synchronous linear reciprocating motions of head toothbrushes 13 property performance period; If two eccentric phase contrasts are 180 degree, then two eccentrics can drive corresponding slide block 11 and realize tandem asynchronous seesawing under the guide effect of driving device support 3, finally drive two opposite linear reciprocating motions of head toothbrushes 13 property performance period.
In the present embodiment, the structure of the head toothbrushes 13 that is adopted as shown in Figure 6, this head toothbrushes contour structures uniqueness, complex process meets human engineering, has symmetric two sub-head toothbrushes, and the bristles on two sub-head toothbrushes is relative, the slit is left in the centre.In addition, for ease of using, be implanted with the bristles of different length on each sub-head toothbrushes, the method for implantation of bristles is: the first step, as shown in Figure 7 and Figure 8, implant brachydont bristle; In second step,, implant equidirectional than the long teeth bristle as Fig. 9 and shown in Figure 10; In the 3rd step,, implant the long teeth bristle of other direction as Figure 11 and shown in Figure 12; In the 4th step,, implant long teeth bristle as Figure 13 and shown in Figure 14.This head toothbrushes operation is more, but makes bristles reach multiple length dimension, multiple angles, and final the realization can be cleaned comprehensively and effectively to tooth.In addition, preferably, as shown in figure 15, the slit about two sub-head toothbrushes intermediate formation 0.1-0.9mm of head toothbrushes is so that the tooth incision.
Figure 16 is the using method sketch map of electric toothbrush in the present embodiment, because this electric toothbrush has 2 head toothbrushes that can carry out reverse linear reciprocating motion, and each head toothbrushes has symmetric two sub-head toothbrushes, thereby when brushing teeth, can clean the inboard and the outside of top and following tooth simultaneously, not only cleaning capacity is strong, and has shortened the time of brushing teeth greatly, improve efficient, improved the utilization rate of motor energy.
Above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, only with reference to preferred embodiment this utility model is had been described in detail.Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical solution of the utility model, and do not break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
