Abstract

The utility model relates to an electric toothbrush, wherein toothpaste can be put in a brush body to realize automatic adding the toothpaste, a column body type rotating brush is adopted on a brush head and the electric toothbrush is applied more conveniently. The purpose-made toothpaste is put in a toothpaste box body in the brush body and is abutted on a butt-joint opening in the box body, and a compressing device is arranged in the box body. A toothpaste packing body is compressed by the compressing device by shifting a control knob, and the fluid toothpaste is conveyed on the brush head by a transmitting pipe under the pressure action. A rotation surface of the brush bristles of the column body type brush is perpendicularly acted on the surfaces of teeth, so the utility model can more deeply remove residues and dental calculus in tooth concave and tooth gaps.

Description

Electric toothbrush

This utility model relates to a kind of electric toothbrush.

At present, known electric toothbrush and toothpaste are splits, and it is not very convenient using; The relative dental surface of the bristle surfaces of revolution all is parallel simultaneously, can not better stretch into teeth space and tooth recess and remove tartar.

The purpose of this utility model is to provide a kind of electric toothbrush, and it and toothpaste organically are combined as a whole, and can add toothpaste automatically, uses more convenient; The bristle surfaces of revolution vertically acts on dental surface, can remove better that tooth meets and the residual and tartar of the meal of tooth recess.

The purpose of this utility model is achieved in that

Brush adopts cylinder formula hairbrush, and hairbrush is along its cylinder central axis rotation, and hairbrush center of rotation axis and whole toothbrush central axis are in the same way.Cylinder formula hairbrush places in the brush housing, it is work surface that the one breach face that is parallel to central axis is arranged on the brush housing, could expose when bristle only rotates to the breach face and clean tooth outside with water, hairbrush by dc motor in the brush body by gear and power transmission shaft driven rotary; Simultaneously have toothpaste to fail the hole on the brush housing, its defeated hole is connected with toothpaste outlet on the brush body.Be provided with compressor in the brush body, be used for the compressible toothpaste of special package body (as threaded body packing toothpaste), the toothpaste mouth docks with docking port in the brush body and is fixing.Compressor is made up of push pedal, leading screw, toothpaste control turn-knob, and leading screw is controlled the turn-knob centre bore by brush handle housing inner support and toothpaste and docked with the centre bore female thread, and the leading screw top is fixed in push pedal.Rotate toothpaste control turn-knob, turn-knob promotes leading screw by the centre bore female thread and travels forward, leading screw promotes push pedal and travels forward, push pedal promotes toothpaste packing body afterbody and compresses forward, fluid toothpaste through the defeated brush housing endosome toothpaste outlet place of managing, is opened switch under pressure, and hairbrush rotates toothpaste and is evenly coated in the hairbrush surface, the brush work surface is touched mutually with tooth, expose in the bristle fast rotational at brush work surface place tooth is cleaned with water.For convenient upper and lower row's tooth cleaned with water the rotating of switch controls hairbrush.

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

In Fig. 1, can see being provided with the toothpaste casing in the brush body, open toothpaste Box Cover [9] toothpaste [10] is put into case, dock and toothpaste is fixed in the casing by on docking port [8] and the toothpaste mouth.Support plate is formed compressor in push pedal [11], leading screw [13], toothpaste control turn-knob [12] and the brush body, rotating turn-knob [12] promotion leading screw [13] and push pedal [11] travels forward, push pedal [11] promotes the toothpaste afterbody and compresses forward, compression packing body inner fluid toothpaste under pressure, the defeated pipe of toothpaste outlet in docking port [8] and toothpaste [4] flows to the intravital toothpaste outlet of brush shell [3], and toothpaste sticks on the hairbrush.

By seeing among Fig. 1, Fig. 2 that hairbrush [2] is vertical cylinder formula hairbrush, hairbrush [2] is along its cylinder central axis rotation, and hairbrush center of rotation axis and brush body central axis are in the same way.Hairbrush [2] passes through gear [14] and gear [6] driven rotary by dc motor [15].

By seeing among Fig. 1, Fig. 2 that hairbrush [2] places in the brush housing corresponding with it [1], it is work surface that there is a breach face that is parallel to the hairbrush central axis brush housing top, hairbrush [2] part bristle is exposed at outside the work surface, hairbrush is exposed at also rotation synchronously of part outside the work surface when the housing internal rotation, utilization is exposed at work surface external rotation bristle tooth is cleaned with water.The brush housing below relative with work surface has defeated manage [4] of toothpaste outlet [3] and the toothpaste on the brush body to communicate, and hairbrush [2] touches mutually with toothpaste outlet [3], and the toothpaste that outlet [3] is located can directly adhere on the hairbrush [2].Block outlet for toothpaste is condensed in outlet [3], can make a brush medicated cap, build after the use by head shapes.
