US Patent No. 3732589 discloses a kind of electric toothbrush, the brush of this patent mainly is made of left and right two rotating brushess that arrange in opposite directions, be connected as a single entity by a pipe between two rotating brushess, the outer wall of described pipe also is provided with bristle, be equipped with the brush axle in the pore of pipe, an end of described brush axle is fixed in the termination of brush holder support.The electric toothbrush of this structure, can scrub the blade of lower teeth and tooth simultaneously, further improved the efficient of brushing teeth, but still there is following defective in this patent: because the restriction of structure, the volume of brush is bigger, waste material not only, and be placed on very uncomfortable and mobile inconvenience in the mouth, influence toothbrushing effect.

The utility model content

The purpose of this utility model is: provide that a kind of brush-head structure is simple, volume is little, when brushing teeth in the comprehensive electric toothbrush of conveniently moving in the mouth.

For achieving the above object, this utility model can be taked following technical proposals:

A kind of comprehensive electric toothbrush of this utility model, comprise brush holder, brush holder support, and brush, described brush is by a left side, right two rotating brushess that are fixedly arranged in opposite directions on the brush axle constitute, the right-hand member of described brush axle is rotatable be arranged in the axis hole of brush holder support upper end and by the axle cap axial location of right rotation hairbrush and this brush right-hand member on described axis hole, the gear teeth of power source by the power transmission shaft in the brush holder support and right rotation hairbrush right side that are located in the brush holder are in transmission connection, a left side, the bristle of right rotation hairbrush is by interior, outer two circle bristles constitute, has the suitable spacing a smaller or equal to tooth thickness between bristle termination, outer ring, a left side and the bristle termination, right outer ring, inner ring bristle termination, a left side and right inner ring bristle termination interlock and overlap or have a gap b less than gap a, a left side, right inner ring bristle is with to brush axis parallel or constitute less angle m, a left side, right outer ring bristle constitutes than mitre n with the brush axis.

Described spacing a is 0.5-5 millimeters, and described gap b is 0-3 millimeters, and described angle m is 0-15 degree, and described angle n is 15-70 degree.

Described angle m is 6 degree, and described angle n is 35 degree, and described spacing a is 3 millimeters, and described gap b is 0 millimeter.

Described left inner ring bristle termination is 1 millimeter with right inner ring bristle termination along the staggered coincidence length that overlaps of axis.

Described power source is made of reducing motor and battery, is provided with union joint between described reducing motor and power transmission shaft.

Compared with prior art the beneficial effects of the utility model are: owing to adopt technique scheme, described brush is made of left and right two rotating brushess that are fixedly arranged in opposite directions on the brush axle, this structure, the brush axle can directly drive left and right rotating brushes and rotate, and is simple in structure; The right-hand member of described brush axle is rotatable be arranged in the axis hole of brush holder support upper end and by the axle cap axial location of right rotation hairbrush and this brush axle right-hand member on described axis hole, this structure has been simplified the drive mechanism of brush holder support upper end, has dwindled the size on the brush holder support; A left side, the bristle of right rotation hairbrush is by interior, outer two circle bristles constitute, a left side, right inner ring bristle is parallel with the brush axis or constitute less angle m(0-15 and spend), inner ring bristle termination, a left side and right inner ring bristle termination interlock and overlap or have less than gap a gap b(0-3 millimeter), this structure, a left side, the hair bar of right inner ring bristle can be scrubbed the land of lower teeth, under centrifugal action, a left side, the termination of right inner ring bristle upwarps, the termination also can brush the land of lower teeth, compare with prior art US Patent No. 3732589, saved pipe, dwindled radial dimension greatly, not only saved material, and be placed on and do not have sticky feeling and conveniently moving in the mouth, toothbrushing effect is good; Left and right outer ring bristle constitutes the degree than mitre n(15-70 with the brush axis), have suitable spacing a(0.5-5 millimeter smaller or equal to tooth thickness between bristle termination, outer ring, a left side and the bristle termination, right outer ring), this structure, by the rotation of left and right outer ring bristle, can be from top to bottom, from bottom to top, from left to right the inboard of scrubbing tooth and the outside, compared with prior art, the outer ring bristle only needs much of that once enclosing, save bristle, simplified the structure, alleviated weight.
