Abstract
The electric toothbrush with rotating bristles has one power part driving one group of bristles in the center of the rotating wheel to rotate via the driving shaft, four rotating wheels in the toothbrush head and one transmission unit for the rotating motion, and the rotating motion inside the toothbrush head is transmitted step by step via the transmission units. The electric toothbrush of the invention has the double functions of tooth cleaning and massage.
Description
The present invention relates to a kind of electric toothbrush of bristle rotation, belong to personal healthcare device.
The toothbrush of people's use at present is that bristle is fixed on the head toothbrushes, does traverse motion during use, and the shortcoming of this teeth brushing way is that toothbrush can only remove the dirt of dental surface, and powerless to the dirt in teeth space, the tooth cavity, so clean rate is very low.
Chinese patent 86210846 has been introduced the electric toothbrush that a kind of bristle can rotate.
The principle of this electric toothbrush is: the worm screw on the motor shaft drives two helical gear rotations that are engaged with, make the spur gear rotation coaxial with helical gear, one group of small Spur gear rotation of two two engagements before and after spur gear drives is positioned on the supercentral bristle rotation of these small Spur gears thereby make.This toothbrush is changed traditional teeth brushing way, every pinch of bristle all can extend in teeth space, the tooth cavity to be cleaned dirt totally with water, do not enter bristle lodging in teeth space, the tooth cavity in flank of tooth rotation, wipe examination flank of tooth massage gingiva, so the clean rate of this toothbrush is high and massage effect arranged.
But from using and make this electric toothbrush of the angle part that still has some deficits:
The first, on a head toothbrushes, can only adorn two row brush hairs by the version of this driving-chain, the arrangement of bristle is not quite even like this, influences toothbrushing effect.
The second, worm screw and two helical gears can only adopt metal material processing at present, and the required precision height, and this makes this toothbrush cost high undoubtedly, influences popularity rate.It is more even to the objective of the invention is to propose a kind of bristle arrangements, and simple in structure and easy manufacturing, cost is low and the electric toothbrush that is easy to popularize.The present invention is by power section [micro machine, battery], and power transmission shaft and head toothbrushes are formed jointly, below in conjunction with accompanying drawing the present invention are elaborated.
Figure 1 shows that a transfer unit that rotatablely moves of forming by four moving runners, its arrangement is tetragon, and each moving runner is positioned on the tetragonal angle, and contacts with moving runner on adjacent two angles, moving runner can be a gear, also can be friction pulley.Wherein 1 is drivewheel, and 2 is transition wheel, and 3 is driven pulley, and 4 is bristle.Its operation principle is: the drivewheel rotation drives two transition wheels contacted with it, and two transition wheels drive jointly again distinguishes contacted driven pulley with it, finishes the transmission that rotatablely moves.
Figure 2 shows that a specific embodiment of the present invention, wherein 8 are power section, are made up of micro machine and battery, and this part is as the toothbrush handle, and 7 is power transmission shaft, and it will rotatablely move and pass to flexible axle 6, and flexible axle drives drivewheel 1 rotation, finishes the conversion of Plane of rotation.The transmission of head toothbrushes internal rotation motion is finished by three transfer units, one of them transfer unit will rotatablely move and transmit to the head toothbrushes rear portion, two other transfer unit is formed the secondary transmission, to rotatablely move to the anterior transmission of head toothbrushes, moving runner 5 is both as the driven pulley of first order transfer unit, as the drivewheel of second level transfer unit, the rotation of moving runner has just driven the rotation of the bristle that is positioned at its center in the head toothbrushes again.2 is transition wheel, and 3 is driven pulley, and 4 is bristle.What changement adopted in the present embodiment is the flexible axle changement.Fig. 3 is the a-a cutaway view of Fig. 2.
Fig. 4 is second kind of embodiment of the present invention, and it adopts the garden bevel gear reversing mechanism, and wherein 1 is drivewheel, and 7 is power transmission shaft, and 4 is bristle, and 9 for forming a pair of garden bevel gear of changement.Its operation principle is conical gear drive and the drivewheel coaxial conical gear rotation coaxial with power transmission shaft, finishes the conversion of Plane of rotation.Present embodiment is except that the changement difference, and remaining structure and operation principle and embodiment shown in Figure 1 are just the same.
Fig. 5 is the third embodiment of the present invention, and it adopts worm gear, worm screw changement, and Fig. 6 is its a-a cutaway view, wherein 1 is drivewheel, 2 is transition wheel, and 3 is driven pulley, and 4 is bristle, 7 is power transmission shaft, 8 are power section, and 10 is worm screw, and 11 is worm gear, moving runner 12 is the transition wheel of first order transfer unit, is again the drivewheel of second level gear unit.Present embodiment is by driving the worm gear that is engaged with the coaxial worm screw of power transmission shaft, thereby make the drivewheel rotation coaxial with worm gear, first order transfer unit at first will rotatablely move and be passed to opposite side by a side of head toothbrushes, two at the corresponding levels transition wheels 12 are again respectively as the drivewheel of two second level transfer units, these two second level transfer units will rotatablely move respectively to the transmission of head toothbrushes front and rear both direction, thereby finished the transmission of head toothbrushes internal rotation motion, the rotation of moving runner has driven the rotation of the bristle that is positioned at its center in the head toothbrushes.
Driving-chain compact conformation of the present invention, transmission loss is little, and noise is little, bristle distributes more evenly rationally, and the dirt ability of removing in tooth seam, the hole is strong, easy to use, economic performance is superior, for personal healthcare provides a kind of device with actual use value.
Claims (5)
1, a kind of by power section, the electric toothbrush of the bristle rotation that power transmission shaft and head toothbrushes are formed, order about the one group of bristle rotation that is positioned on the moving runner center on the head toothbrushes by power transmission shaft by motor, it is characterized in that: lining up tetragonal four moving runners in the head toothbrushes is a transfer unit that rotatablely moves, each moving runner is positioned on the tetragonal angle separately, and contact each other with moving runner on adjacent two angles, one of them is drivewheel (1), moving runner on adjacent two angles is transition wheel (2), moving runner on the diagonal angle is driven pulley (3), and the motion of head toothbrushes internal rotation is to be transmitted step by step by above-mentioned several same transfer unit; When adopting the crossing at a certain angle mounting means of drive shaft axis and moving runner axis, changement is set in the toothbrush.
2, according to claim 1 described electric toothbrush, it is characterized in that: moving runner can be a gear, also can be friction pulley.
