Description

The actuating device of electric toothbrush

Affiliated field

The present invention relates to electric toothbrush, particularly relate to the actuating device of electric toothbrush.

Background technology

Toothbrush is indispensable articles for use in people's daily life.Current toothbrushes mostly is manual type, and promptly the body of rod one end of toothbrush is equipped with bristle, and the other end is the shank that is used to hold, and during use, grasps shank, and the wrist that swings back and forth or arm make bristle backwash on tooth of toothbrush moving.There is the inconvenience part in the use in this manual type toothbrush, and for example, the swing by wrist or arm is brushed bristle on tooth moving, because the hunting frequency of wrist or arm is lower, therefore, the speed of brushing teeth is slower; Need be with manpower as power, when particularly being difficult for the tooth position of brush, often owing to the inconvenience trouble that becomes of brushing teeth of exerting all one's strength at the brush rear portion.

In order to solve the inconvenience of manual type toothbrush, once the someone proposed electric toothbrush.This electric toothbrush is powered to motor by battery, and the bristle that revolution drives toothbrush head rotates and since electric toothbrush without wrist or arms swing, save manpower, and it rotates evenly, thus make brush teeth become easily.But present being seen electric toothbrush is owing to the defective on the drive mechanism, and its kinetic energy transfer rate is lower, wastes energy; And not steady in the transmission process, noise is bigger.

Therefore, need the actuating device of electric toothbrush be improved, with the convenient part of further more effective performance electric toothbrush.

Summary of the invention

The object of the present invention is to provide a kind of actuating device of electric toothbrush, this actuating device has high transfer rate, and stable drive is reliable.

The object of the present invention is achieved like this: a kind of actuating device of electric toothbrush, this actuating device is provided with the rotation input and the rotation outfan that is connected with head toothbrushes that links to each other with motor, connect by the tooth case between described rotation input and the rotation outfan, be provided with deceleration device in the tooth case.

The actuating device of aforesaid electric toothbrush, described tooth case includes tooth block and tooth case lid, and described tooth case lid is connected on the tooth block, the element of deceleration device in this tooth case lid and tooth block together support and the ccontaining tooth case.Described tooth case is fixed on the motor by the bipod of tooth block and the round platform and two locating holes of motor front end.

The actuating device of described electric toothbrush, wherein, described deceleration device is a mechanical reduction gear.Further, be arranged with by first driven gear and the affixed transition gear group that constitutes of second driving gear on the axle of described tooth block, this first driven gear meshes with first driving gear that is fixed on the electric machine rotational axis that stretches into the tooth block, be arranged with second driven gear on the axle of described tooth case lid, second driving gear engagement on this second driven gear and the tooth block realizes deceleration.

Described second driven gear is connected with the swingle that drives the head toothbrushes rotation by a union joint.

The location is provided with the tabletting of pressing to the tooth case lid on the described tooth case lid, and this tabletting is inserted in three posts that are provided with on the tooth case lid and tightens, and locatees second driven gear, realizes the precision engagement of second driven gear and second driving gear, reduces noise.

The actuating device of electric toothbrush provided by the invention, this actuating device adopts the structure of tooth case, the element of deceleration device in the tooth case lid of this tooth case and tooth block together support and the ccontaining tooth case, therefore, actuating device of the present invention has kinetic energy transfer rate height, stable drive is reliable and noise is low, the life-span is long, be easy to advantage such as assembling.

The specific embodiment

To shown in Figure 3, be the structure of the electric toothbrush that contains actuating device of the present invention referring to Fig. 1.This electric toothbrush mainly comprises power pack and actuating device.Wherein, power pack is to power to motor with battery.As shown in the figure, link to each other by the positive negative electricity level of disjunctor dish spring 1 two batteries, other end at battery is connected with the positive level of battery with positive level sheet 3, link to each other with the negative pole of battery with negative plate 4, battery cathode sheet is connected with motor 6 negative poles by battery-motor leads 5, the positive level of battery sheet is connected with a foot of switch 8 by battery-switch wire 7; Another foot of switch 8 is connected by a switch-motor leads 9 and the positive level of a motor sheet, therefore, can be switched on or switched off power supply, make revolution or stop by pressing switch gum cover 10.

Actuating device of the present invention mainly adopts the tooth box structure that is provided with mechanical reduction gear in it, to reduce rotating speed and to improve moment of torsion.To shown in Figure 5, first driving gear 11 is fixed on the rotating shaft of motor referring to Fig. 2, and motor drives first driving gear 11 and rotates.Tooth block 12 is fixed on assigned position on the motor by the round platform and two locating holes of motor front end, is compressed by the motor press strip again.Be inserted on the axle of tooth block by the be connected transition gear that constitutes of first driven gear 13 and second driving gear 14,, drive first driven gear 13 by first driving gear 11 and make backward rotation, finish for the first time because of the different drive systems of the number of teeth and slow down by gears engaged.Because second driving gear 14 and first driven gear, 13 coaxial being connected, both do reverse rotation simultaneously.Tooth case lid 15 is fastened on assigned position on the tooth block 12, to prevent first driven gear, 13 bobs.Second driven gear 16 is inserted on the axle of tooth case lid 15, and second driving gear 14 drives second driven gear 16 by gears engaged and makes backward rotation, realizes again simultaneously slowing down, to reach the power speed that tooth cleans the teeth required of protecting.Three posts that tabletting 17 is inserted in tooth case lid 15 tighten, and locate second driven gear 16, make the engagement between second driving gear 14 and second driven gear 16 steadily accurate, reduce noise simultaneously.Second driven gear 16 is realized rotating with the interlock of swingle 19 by union joint 26, and wherein swingle 19 is fixed on the assigned position of union joint 26, and union joint 26 inserts second driven gear 16.

Do for driven rotary 18 and to decide angle and come and go and rotate, the head (part that promptly has bending) of swingle 19 is inserted swivel head 18 assigned positions, because swingle 19 heads and its main part decentraction, therefore swingle 19 heads will become circumference to rotate, because location axle sleeve 21 is fixed to locating shaft 20 on the toothbrush housing, and locating shaft 20 can be rotated, be that the axle center rotates back and forth with swingle 19 thereby make swivel head 18 with locating shaft 20.

Too big for avoiding swingle 19 heads to fluctuate when rotated, first centring ring 22 is inserted in swingle 19 assigned positions, for preventing the toothbrush water inlet, first water proof ring 23 is inserted in swingle 19 assigned positions.Too big for avoiding swingle 19 afterbodys to fluctuate when rotated, second centring ring 24 is inserted in swingle 19 assigned positions, reuse second water proof ring 25 is inserted in the swingle assigned position, thereby plays dual waterproof action.
