Abstract

The utility model discloses an electric toothbrush which is characterized in that the vertically vibratile actions when people brush teeth can be replaced, and the effect is better. Compared with ordinary electric toothbrushes, a difference is that the brush bristles of the toothbrush move upward and downward along tooth gaps, rather than rotate; thereby, a switch needs not be toggled repeatedly in the process of tooth brushing, and the electric toothbrush is in accordance with the normal habit of tooth brushing of people; therefore, the utility model is a good tool of mouth cavity cleaning for people.

Description

Electrically operated tooth brush

A kind of oral appliance of cleaning teeth.

At present, the widely used toothbrush of people mostly is manual toothbrush, and it is electronic rotary toothbrush that small part is also arranged, and both brush body was a rotary body, and " the electronic rotary toothbrush " as ZL85201246, ZL85201485 is this working method.For manual toothbrush, people get used to the method for laterally brushing.As everyone knows, this teeth brushing way is very unscientific, and normally the method for brushing should be along the vertical rider-type brush method of teeth space.This brush method brush front tooth is easy to, during the tooth of brush both sides, because the gingival edge semicircular in shape, and be subjected to the obstruction of two cheeks, therefore, vertical perpendicularity is difficult for grasping, and often makes that toothbrush is oblique to brush on the gum, bleeding gums appear, tartar is not brushed, and, cause the gingival papilla circulation to be obstructed, form the local extravasated blood of gum, oedema formation inflammation, long-term pessimal stimulation easily causes the generation of periodontal disease phenomenon; For electronic rotary toothbrush, though holding the hand of toothbrush, people do not need vertical vibration, its many operation that strict control brush body turns to---control change-over switch action.This be because, when brush front upper tooth or lower tooth the inside, the direction of holding toothbrush from the right hand (or left hand), bristle must be along teeth space (or clockwise) rotation counterclockwise, otherwise, when brush front lower tooth or upper tooth the inside, bristle must be along teeth space (or counterclockwise) rotation clockwise, and both the direction of rotation of bristle must turn to gingival edge from the gum root.Could guarantee so not damage gum, but people often get used to the reciprocal successively tooth of scrubbing, this is not only a custom, but also the toothpaste that helps in the mouth foams, and promotes the effect of brushing teeth.Thus and thus, in the process of once brushing teeth, will stir change-over switch tens times so even more.If accidentally direction of rotation is done anti-, toothbrush is directly brushed to gingival edge, will damage gum, above-mentioned phenomenon appears.And this according to different facings position, the electronic rotary toothbrush that turns to of decision is unsuitable for the people of children, old man and low intelligence, because they use this rotary toothbrush to be easy to occur mistake on the direction of rotation.

The purpose of this utility model: design a kind of bristle and the parallel electric toothbrush that relatively moves of tooth seam.

The utility model technical solution is: fixedly the swinging axle 3 perpendicular forks 4 of toothbrush link to each other, and fork 4 drives the swing arm 6 of making circular motion by micro machine, and toothbrush is moved up and down along facing.

The utility model has the advantages that: because bristles moves up and down along facing automatically, so no matter be the positive upper teeth of brush, positive lower teeth, upper teeth the inside, lower teeth the inside, be a manner of execution, do not need position according to the face of brushing teeth, stir change-over switch repeatedly, both facing position and micro machine irrelevant to rotation direction.On the other hand, it can satisfy the reciprocal successively tooth-brushing habit of people, and old children all uses.Can avoid because of the brush method improper, and the above-mentioned phenomenon that causes.

Below in conjunction with description of drawings the utility model most preferred embodiment.

Fig. 1, Fig. 2 are the utility model outward appearance generalized section.

In Fig. 1, Fig. 2, driven gear, 8 driving gears, 9 protect handle, 10 shells, 11 motors, 12 batteries, 13 frames in 1 toothbrush, 2 shaft joints, 3 swinging axles, 4 forks, 5 fork grooves, 6 swing arms, 7.

In Fig. 1, when micro-motor power supply is connected, driven gear 7 rotations in the micro machine output shaft drives by driving gear 8, on interior driven gear 7 ends, a swing arm parallel with it 6 is arranged, the swing arm 6 of making circular motion inserts in the fork groove 5, make swinging axle 3 reciprocally swingings of fork 4 and coupled fixedly toothbrush, thereby realize that toothbrush moves back and forth up and down along facing.

Claims (2)

1, a kind of electric toothbrush is made up of micro machine, travelling gear and toothbrush, and micro machine drives the toothbrush rotation by travelling gear, and feature of the present utility model is: fixedly the swinging axle 3 perpendicular forks 4 of toothbrush link to each other.

2, electric toothbrush according to claim 1 is characterized in that: on interior driven gear 7 end faces swing arm parallel with it 3 is arranged.
