At present, current toothbrushes has the single face and the electronic face of cylinder to plant two kinds of toothbrushes of hair.It generally is to finish the cleaning oral cavity health with the simple motion of hands that single face is planted hair, because the tartar of action very difficult removing teeth space lack of standardization and tooth inboard; Even and electronic cylinder is planted mao toothbrush rotating speed pad is comparatively fast arranged,, and damage gingiva because pad is wide, straight excessively.
Summary of the invention
The object of the present invention is to provide a kind of rotary electric toothbrush, it can not only reasonably be removed tartar rapidly and vertically brush teeth, and can not damage gingiva.
The object of the present invention is achieved like this: be fixed on and be associated with the brush axle on the actuating device of motor in the handle, the convex head in the place ahead of brush axle directly is inserted in three pads in brush axle the place ahead and is downwards in the circular arc inner groovy; Plant bristle on the cylinder of brush axle outside cylinder.Brush axle is to be screwed on the handle of toothbrush by pillar.When motor drove the rotation of brush axle by actuating device, the brush on the brush axle outside cylinder was also along with rotation.Have in brush axle the place ahead to have pad, rotating speed has speed, direction that last purgation branch is arranged, feasible more simple and convenient, the Anti-dental injury gum of brushing teeth.
Description of drawings
Below in conjunction with drawings and Examples the present invention is done detailed explanation.
Fig. 1 is a structural representation of the present invention.
Among Fig. 1,1, pad 2, brush axle 3, brush 4, pillar 5, dividing plate 6, handle 7, switch 8, motor 9, transmission gear for electric motor
Embodiment
In the drawings, this electric toothbrush has pad (1), brush axle (2), brush (3), pillar (4), dividing plate (5), handle (6), switch (7), motor (8) and actuating device (9) to form.Intrinsic miniature magneto (8) and switch (7) in handle (6), their connections by circuit are realized the function of speed up and down of toothbrush.Motor (8) is gone up and is associated with semicircular brush axle (2) on transmission gear for electric motor (9) axle center, brush axle (2) passes the supercentral dividing plate of pillar (4) (5) center hole, and the convex brush (3) that cylinder is planted hair directly is embedded in the inner groovy that has only the downward circular arc that three pads (1) of 1/3rd form mutually.Because brush axle (2) is a cantilever position, in order to prevent moving and distortion of brush axle (2), to locate in the import of pillar (4) and the dividing plate (5) of its central part, the diameter that will brush axle (2) changes, and guarantees that brush axle (2) does not move forward and backward.The size variation that the import of pillar (4) and dividing plate (5) are located is in order to prevent people when brushing teeth, and saliva penetrates into the problem that causes line short in the handle (6).
During use, toothpaste directly is squeezed on the brush (3), opens switch (7), selection function is brushed teeth, because the protection of three pads (1), not only conveniently easily brushes teeth but also has protected gingiva injury-free, has played the effect of cleaning teeth.During replacing, back out pillar (4) leading portion, change new both can, so i.e. safety health again.
Claims (3)
1, a kind of electric toothbrush, be made up of pad (1), brush axle (2), brush (3), pillar (4), dividing plate (5), handle (6), switch (7), motor (8) and transmission gear for electric motor (9), it is characterized in that: three pads (1) form the inner groovy of a downward circular arc.
2, electric toothbrush according to claim 1 is characterized in that: brush axle (2) the place ahead is that convex head, back are the circular shafts of semicircle.
3, electric toothbrush according to claim 1 is characterized in that: switch (7) can be controlled above-below direction, fast jogging speed.
