Description

Electric toothbrush

This utility model relates to a kind of electric toothbrush, and particularly a kind of bristle has the automatic tooth-brush that rotates and swing.

Present ordinary toothbrush, brush holder and brush holder and bristle are fixed on one, need hold brush holder and swing up and down and brush teeth, if yet brush teeth as Dragsaw type with this toothbrush, can not effectively remove the between cog residue, even easily cause ganoid damage, suffer from and cause disease tooth.

The purpose of this utility model provides a kind of electric toothbrush, when brushing teeth, does not need manually, only need toggle switch, electro-motor can make the bristle rotation by internal mechanism and swing up and down, and implements the correct action of brushing teeth, remove the between cog residue, the infringement of avoiding the incorrect action of brushing teeth to bring.

The toothbrush of this utility model, by the brush holder of releasable connection, brush holder and bristle are formed, and it is characterized in that:

Said brush holder is a hollow cylinder, is provided with motor and battery in the tube, and the brush holder rear end is covered by lid, and the conducting strip on said motor, battery and the bonnet forms the on-off circuit of motor by switch on the brush holder and line thereof.

On the said brush holder inner groovy is arranged, the vibration seat is arranged in this inner groovy, the both sides of its front end form some circle hole grooves respectively, the rear end forms groove, the circle hole groove of front end is inserted with rotor, transverse plane fasten bristles body on this rotor, the rear end groove is then adorned sliding shoe, body brush is also inserted in this sliding shoe upper end, there is a square hole in the central authorities of sliding shoe, two projections of the biasing of inwall up and down in the square hole, cooperatively interact by the rotation of a wave vibrating shaft and square hole and to promote sliding shoe and swing, the drive body brush swings, and the gear 4 of wave vibrating shaft front end drives the rotor that is engaged with and is clockwise, counter rotation drives fixed body brush rotation on the rotor.Brush holder 2 front end faces have a discharge outlet, are through with a drainage with water filling port set on the handle of brush holder rear end.Then cover a hairbrush fixed panel on the inner groovy of brush holder.

On the axle of said motor another gear of gears engaged is arranged, in the time of the wave vibrating shaft fit of the rotating shaft that this another gear extends forward and brush holder, brush holder and brush holder are chimeric just to be fixed, and this fit all is dismantled and assembled mechanical connection with chimeric the connection.

The gear of said wave vibrating shaft front end preferably merges the diclinic herringbone bear that forms by two monocline conical gears, so as simultaneously with the awl tooth engagement of four rotors, promotes four rotors and forms clockwise or counter rotation simultaneously.

Said vibration seat can also be made other shapes, and for example front end two side bottoms are provided with round slot bore, and then bottom portion forms concavo-convex concavo-convexly, and its recess constitutes the tracks that sliding shoe swings.

Said rotor is an inverted cone, and there is a circle hole groove on the last plane of cone, inserts fixing for body brush.

Said sliding shoe is a square, and the both sides, upper surface have circle hole groove, inserts fixing for body brush.

Said body brush lower end is a cylinder, and its waist place is glomeration body slightly, fixing hairbrush on this spheroid, and said hairbrush fixed panel is provided with the spherical hole that passes for body brush.After body brush inserts sliding shoe, this sphere hole cooperates the formation body brush to swing with the spheroid of body brush fulcrum.

Characteristics of the present utility model and function are as follows:

1, simple in structure, convenient disassembly, volume is little, and is easy to carry.

2, easy to use, only with hand starting switch, bristle promptly are clockwise, and counter rotation and swinging makes the tooth each several part can both be subjected to the cleaning action of toothbrush.

The utility model is described in further detail below in conjunction with accompanying drawing.
