The purpose of this utility model be to provide a kind of simple in structure, change cleaner, the labour-saving electric toothbrush of vertically brushing teeth and brush teeth that bristle head is convenient, can realize ideal.

The purpose of this utility model is achieved like this, and a kind of electric toothbrush comprises bristle head 2, brush body 11, and described bristle head 2 is provided with radial bristle 1, at the end tool brush axle 3 of bristle head 2; The centre of described brush body 11 is a hollow die cavity, is provided with actuating unit in it, and the unlatching and the positive and negative rotation direction of two-way switch 12 control actuating units arranged; Described actuating unit is made up of motor 17, decelerator 20, output shaft 21, motor 17 is connected with the movable end of two-way switch 12 by lead 16, the stiff end of two-way switch 12 is connected with attaching plug 14 by lead, decelerator 20 is installed on the motor 17, be connected with an end of output shaft 21 on it, the other end of output shaft 21 is connected with an end of connecting axle 22, and the other end of connecting axle 22 is connected with brush axle 3; Described connecting axle 22 is located in the die cavity of axle bed head 8, and axle bed head 8 is between bristle head 2 and brush body 11, and the sealing of one end is installed on the axle bed 10, and axle bed 10 sealings are mounted in the die cavity mouth of pipe 23 of brush body 11 front ends; The rear end of described brush body 11 is provided with bonnet 13; One side of described bristle head 2 also is provided with sheath 5, and an end of sheath 5 is installed on the axle bed head 8.

This utility model is because after adopting said structure, bristle head 2 is by two-way switch 12 controls, and under the drive of motor 17, decelerator 20, by output shaft 21, connecting axle 22, brush axle 3 just/reverse turn forms the rotation cylinder, just can reach ideal perpendicular brush state when brush body 11 horizontal positioned; Simultaneously because being connected between bristle head 2 and the connecting axle 22 is detachable, thereby the bristle head of changing is a brush axle of being with bristle, and it is simple in structure, and cost is low, the also corresponding reduction of use cost; In addition, sheath 5 is provided with the collision and the damage that can effectively prevent in use the around teeth oral soft tissue.

Below in conjunction with accompanying drawing this utility model is further described below.

Accompanying drawing is an example structure sketch of the present utility model.

Axle bed head 8 of the present utility model also can integral production with axle bed 10.

The middle tool axis hole 4 of connecting axle 22 of the present utility model, the brush axle 3 of bristle head 2 one ends inserts in the axis hole 4 of connecting axles 22 1 ends, and in addition spiral shell is solid by screw 24.This mode of removably connecting is convenient to change separately bristle head 2.Generally can adopt axle sleeve to be connected between the output shaft 21 of decelerator 20 1 ends of the present utility model and the connecting axle 22, also can adopt other connected mode certainly.

Sheath 5 of the present utility model is circular-arc, offers flange hole 6 on sheath 5, cooperates with flange 7 on the axle bed head 8 by flange hole 6, has realized that sheath 5 is connected with the dismountable of axle bed head 8.The effect of sheath 5 is in order to prevent bristle 1 on the bristle head 2 and the collision of brushing axle 3 and around teeth oral soft tissue.

This utility model leaks electricity for the inner intracavity water inlet that prevents brush body 11, sets up sealing ring 9 respectively between axle bed head 8 and axle bed 10, sets up back seal cover 15 at the rear of motor 17.

Two-way switch 12 of the present utility model is located on the housing of brush body 11, and the stiff end of two-way switch 12 is connected with attaching plug 14 by lead, and the movable end of two-way switch 12 is connected with lead 16 on the motor 17 by lead.Two-way switch 12 is controlled the forward and backward of motor 17 respectively and is stopped.Attaching plug 14 of the present utility model is arranged on outside the bonnet 13, and bonnet 13 sealing and fixing are on the die cavity mouth of pipe of brush body 11 rear ends.

Decelerator 20 of the present utility model is fixed on the motor 17, and by 18 engagements of the motor gear on driven gear in it 19 and the motor 17.By one or more levels deceleration of decelerator 20, make bristle head 2 reach ideal rotation rotating speed.

This utility model is to come work like this, at first by attaching plug 14 and extraneous energising, press two-way switch 12 then, make the clockwise or inverse time direction rotation of motor, after decelerator 20 decelerations, power is by output shaft 21 outputs of decelerator 20, because output shaft 21 fixes with connecting axle 22, connecting axle 22 again with bristle head 2 on brush axle 3 fix, thereby the rotation of output shaft 21 drives connecting axle 22 successively, 3 rotations of brush axle, thereby realize the suitable of bristle head 2 or rotation counterclockwise, can carry out stroke the circle method and the vertical transfer method of science, staff only plays to hold takes effect, both laborsaving, cleaning effect is good again, and gingiva is not played any injury.
