Abstract
The invention provides an electric toothbrush head, which comprises a brush rod, a guide sleeve, a transmission drive rod, a square-head brush, a bracket, a rotary round-head brush and a rotating shaft, wherein the guide sleeve is arranged in the brush rod; the transmission drive rod is arranged in the guide sleeve; the bracket is arranged at one end of the brush rod; the square-head brush is arranged on the bracket in a manner of swinging up and down; the rotary round-head brush is rotationally arranged at one end of the brush rod, and is adjacent to the square-head brush; the transmission drive rod penetrates through the square-head brush and is connected with the rotary round-head brush; the rotating shaft is arranged at the lower end of the rotary round-head brush; a drive shaft is arranged at one end of the rotary round-head brush; and a curved surface matched with the drive shaft is arranged on the back surface of the square-head brush. The electric toothbrush head is simple in structure and good in cleaning effect; the transmission drive rod extends into a transmission clamping groove of the rotary round-head brush to directly drive the rotary round-head brush to carry out rotary movement; and meanwhile, the square-head brush is driven to vertically swing up and down by virtue of the action force of the drive shaft of the rotary round-head brush on the curve of the square-head brush which swings up and down, so as to realize three-dimensional multi-directional movement of bristles.
Description
Technical field
The present invention relates to toothbrush art, particularly relate to a kind of electric toothbrush head.
Background technology
Toothbrush is a kind of utensil for cleaning teeth used in people's daily life.Electric toothbrush common in the market mainly contains brushhead vibration motion, brush clockwise and be rotated counterclockwise, the relative brush holder side direction of brush and forward, the motion mode such as linear movement backward.These toothbrush head motion modes, its brush driving mechanism and toothbrush motion simply to change to relative complex from relative, motion mode also still rests on bristle two dimensional motion, how to break original designing axiom, brush is allowed to realize three-dimensional motion, automatically to be exerted pressure up and down gum massage, dental bed by bristle while cleaning teeth, a lot of research staff have also been made a lot of design and conception, but all because of its structure too complexity be difficult to come true.Therefore, need one to provide simple production, there are little motion parts, and multiple clean and bristle motion can be provided simultaneously to complete the toothbrush of clean, the health care task of tooth.
Summary of the invention

The problem to be solved in the present invention is to provide a kind of electric toothbrush head, too complicated to overcome structure in prior art, is difficult to realize three-dimensional motion, the defect of cleaning effect difference.
(2) technical scheme
For solveing the technical problem, the invention provides a kind of electric toothbrush head, comprising brush holder support, fairlead, transmission drive rod, square toes brush, support, rotation round end brush and rotating shaft; Described fairlead is arranged in described brush holder support; Described transmission drive rod is arranged in described fairlead; Described Bracket setting is in one end of described brush holder support; The setting that described square toes brush can swing up and down on the bracket; Described rotating one end being arranged on described brush holder support of rotation round end brush, adjacent with described square toes brush; Described transmission drive rod is connected with described rotation round end brush through described square toes brush; The lower end of described rotation round end brush is provided with described rotating shaft; One end of described rotation round end brush is provided with driving shaft; The back side of described square toes brush is provided with the curved surface coordinated with described driving shaft.
Further, one end of described transmission drive rod is eccentric shaft, and described rotation round end brush 7 is provided with the transmission draw-in groove coordinated with described eccentric shaft.
Further, described electric toothbrush head also comprises limiting card; Described limiting card is fixed on one end of described brush holder support; Described limiting card upper end and the grafting of described square toes brush.
Further, described limiting card shape is U-shaped.
Further, the other end of described rotation round end brush is provided with alignment pin.
Further, on described transmission drive rod, also cover has sleeve pipe, and the described square toes brush back side is provided with the groove coordinated with described sleeve pipe.
(3) beneficial effect
Electric toothbrush head of the present invention, structure is simple, cleaning effect is good, in the transmission draw-in groove adopting transmission drive rod to extend into rotate round end brush, Direct driver rotates the rotary motion of round end brush, rely on the driving shaft active force rotating round end brush in the curved surface of the square toes brush swung up and down simultaneously, drive square toes brush to swing vertically, thus realize the 3 D multi-directional motion of bristle.

Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
As shown in Figures 1 to 4, a kind of electric toothbrush head of the present invention, comprises brush holder support 1, fairlead 2, transmission drive rod 3, square toes brush 4, support 5, rotates round end brush 7 and rotating shaft 8; Described fairlead 2 is arranged in described brush holder support 1; Described transmission drive rod 3 is arranged in described fairlead 2; Described support 5 is arranged on one end of described brush holder support 1; What described square toes brush 4 can swing up and down is arranged on described support 5; The rotating one end being arranged on described brush holder support 1 of described rotation round end brush 7, adjacent with described square toes brush 4; Described transmission drive rod 3 is connected with described rotation round end brush 7 through described square toes brush 4; The lower end of described rotation round end brush 7 is provided with described rotating shaft 8; One end of described rotation round end brush 7 is provided with driving shaft 10; The back side of described square toes brush 4 is provided with the curved surface 13 coordinated with described driving shaft 10.
