Abstract

The utility model provides an electric toothbrush head which has the following structure: a housing is respectively sleeved with a driving shaft and a driven shaft which are parallel with each other, one end of the driving shaft is provided with a connecting piece, the other end of the driving shaft is provided with bristle, one end of the driven shaft is arranged in the housing, gears which are engaged with each other are respectively fixed on the position of the end of the driven shaft which corresponds to the driving shaft, the other end of the driven shaft is provided with bristle, and the bristle on the driving shaft and the bristle on the driven shaft are arranged on the same side of the housing and correspond to each other on the position. The shaft body on the driving shaft, between the connecting piece and the housing, is sleeved with a sheath, and the sheath is whirly connected with the housing. When in use, the electric toothbrush head is coaxially and movably connected with an output shaft of a mini-DC motor in a common toothbrush base by the connecting piece. The two gears are mutually engaged with each other to drive the driving shaft and the driven shaft to oppositely turn, so that the bristle which is arranged at the same end of the two shafts also oppositely rotates, wherein the bristle has larger area. After being assembled with the common toothbrush base, the toothbrush head effectively overcomes the relative defects of the background technology and has good tooth cleaning effect.

Description

Electric toothbrush head

Technical field

This utility model relates to a kind of electric toothbrush head.

Background technology

At present, existing electric toothbrush head is that an end has connector, the other end that the driving shaft of bristle is arranged.During use, by the coaxial flexible connection of output shaft of the miniature cocurrent electromotor in connector and the conventional toothbrush seat.Can change head toothbrushes easily according to the operating position of bristle.Owing to only at a uniaxial end bristle is set, therefore, the area of bristle is less and be one-directional rotation, consequently the poor effect that cleans one's teeth.

The utility model content

The technical problems to be solved in the utility model provides a kind of electric toothbrush head, after this electric toothbrush head is equipped with conventional toothbrush seat, has the preferable advantage of the effect of cleaning one's teeth.

For solving the problems of the technologies described above, the structure of this utility model electric toothbrush head is: housing respectively with driving shaft that is parallel to each other and driven axle socket, one end of driving shaft has connector, the other end that bristle is arranged, one end of driven axle places in the housing, corresponding position fixing pitch wheel respectively on this end of driven axle and the driving shaft, the other end of driven axle has bristle, and the bristle on the driving shaft is in the same side of housing and corresponding on the position with bristle on the driven axle.

During use, by the coaxial flexible connection of output shaft of the miniature cocurrent electromotor in connector and the conventional toothbrush seat.

After adopting above technical scheme; by being meshing with each other of two gears; drive the rotation in opposite directions of driving shaft, driven axle; make the bristle that is arranged on the same end of described diaxon also realize rotating in opposite directions; the area of bristle is bigger, like this, can clean effect and better protect effect completely with water to each face of tooth and teeth space performance; minimizing has improved the effect that cleans one's teeth greatly to the stimulation of gingiva.

Therefore, after this electric toothbrush head is equipped with conventional toothbrush seat, effectively overcome the related defects of background technology, had the preferable advantage of the effect of cleaning one's teeth.

On the axis body between connector and the housing, be with sheath on the described driving shaft, and sheath and housing spin.

The specific embodiment

Below by embodiment and accompanying drawing thereof this utility model is done explanation in further detail:

Referring to Fig. 1-Fig. 3: form up and down by the circular dividing plate of the level of space 14, two circular shroudings 11 of the level of arranging up and down by the hollow cylinder 1 of both ends open up and down, two for housing.Two dividing plates 14 are installed in the inner chamber middle part of cylinder 1, make cylinder 1 from top to down be divided into three chambers.For ease of processing and assembling, remove two shroudings 11 on the housing after, along axis cylinder 1, two dividing plates 14 have been carried out partly cuing open, back three's homogeneous is divided into two.

In the cylinder 1 of half, have the semicircle slotted eye 16 of two same specifications on the outside vertical plane of each dividing plate 14, and two semicircle slotted eyes 16 on the upside dividing plate 14 are corresponding on the position respectively with two semicircle slotted eyes 16 on the downside dividing plate 14; After with two half cylinder 1 butt joints, on upside dividing plate 14 and downside dividing plate 14, respectively form the circular slotted eye of arranging about two 15.

The shrouding 11 of upside has two circular ports 13 of coaxial line respectively corresponding to two circular slotted eye 15 places of upside dividing plate 14, and the shrouding 11 of downside has the screwed hole 12 of a coaxial line corresponding to circular slotted eye 15 places, right side of downside dividing plate 14.

The stage casing from top to down of driving shaft 7 is provided with bearing 71, gear 72, bearing 73, and the lower end from top to down of the driven axle 6 that parallels with driving shaft 7 is provided with bearing 61, gear 62, bearing 63; The shrouding 11 of upside is sleeved on the stage casing of driving shaft 7, driven axle 6 and is higher than bearing 71, bearing 61 by two circular ports 13, and the shrouding 11 of downside is sleeved on the stage casing of driving shaft 7 and is lower than bearing 73, bearing 63 by screwed hole 12; Bearing 61, bearing 63 place two circular slotted eyes 15 in left side successively, gear 62 places in the intermediate cavity, bearing 71, bearing 73 place the circular slotted eye 15 of two of right side successively, gear 72 places in the intermediate cavity, and gear 62, gear 72 be meshing with each other (that is: on the lower end of driven axle 6 and the driving shaft 7 corresponding position fixedly pitch wheel 62, gear 72) respectively; Two shroudings 11 all are separately positioned on the two ends up and down of cylinder 1 by trip bolt.Like this, make housing respectively with driving shaft 7 that is parallel to each other and driven axle 6 sockets, the lower end of driven axle 6 places in the housing.

The lower end of driving shaft 7 has connector 5, the top of claw shape to be set with rubber sleeve 3, and the upper end of rubber sleeve 3 has bristle 31, and connector 5 is the routine techniques part.On the axis body between connector 5 and the housing, be with sheath 4 on the driving shaft 7, and under sheath 4 precessions in the screwed hole 12 on the side seal board 11.

The top of driven axle 6 is set with rubber sleeve 2, and the upper end of rubber sleeve 2 has bristle 21, and the bristle 31 on the driving shaft 7 is in the upside of housing and corresponding on the position with bristle 21 on the driven axle 6.

During use, by the coaxial flexible connection of output shaft of the miniature cocurrent electromotor in connector 5 and the conventional toothbrush seat.

Above-described only is a kind of embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from this utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
