Specific embodiment
The embodiment of the present invention is described in detail below.
Electric toothbrush 1 as shown in Figures 1 to 6, including handle 10, brush head 20 and charging socket 30, the handle 10 wrap
Shell 101, the switch button 103 of the internal component 102 being arranged in inside the shell 101 and setting on the housing are included,
The internal component 102 include machine core shelf 1025 and be fixed on the machine core shelf 1025 motor 1021, battery 1022,
Pcb board 1023.The brush head 20 include brush pot 201, the brush head connector 203 that is connected in the 201 lower end cavity of brush pot and
Bristle portion 202 positioned at 201 head of brush pot.
The electric toothbrush, including handle and brush head, the handle are in prism structure, and its top is along the similar prism
Axial shrink to the internal direction of triangular prism is adapted to the brush head, the bristle plane of the electric toothbrush and the prism its
In the angle in a face be 30 °~60 °, it is preferred that the bristle plane of the electric toothbrush and one of face of the prism
Angle be 45 °.
It is more preferably similar positive three in the preferably similar triangular prism of the prismatic handle and similar tetragonous rod structure
Prism and square prism structure.
Preferably, the seamed edge of the prism has carried out chamfered.It is protruded to outside prism the side of the prism
Cambered surface.
As shown in Figure 3 and Figure 4, the lower end of the handle 10 is a kind of Quasi tri-prism structure, and its top is along described similar
Axial shrink to the internal direction of triangular prism of triangular prism is adapted to the brush head 20, the bristle plane of the electric toothbrush 1 and institute
The angle for stating one of face of triangular prism is 30 °~60 °.The grip portions of handle 10 are arranged to triangular prism structure, and are made
The angle for obtaining 30 °~60 ° of formation between the bristle plane of brush head and one of face of triangular prism, can make toothbrush use in this way
The bristle and tooth that person naturally makes toothbrush when brushing teeth can effectively entangle so at the time of contact at certain angle
By the undesirable tooth-brushing habit of bristle perpendicular contact tooth plane when just brushing teeth.The parallel dental surface of bristle plane is brushed teeth, bristle
It is difficult to clean out the spot in interdental gap and gingival sulcus, and adjusts contact of the bristle plane of toothbrush with tooth
Face is at an angle to be more conducive to cleaning out the spot in teeth space.
Preferably, the similar triangular prism is similar regular triangular prism.Best, the bristle plane of the electric toothbrush and institute
The angle for stating one of face of triangular prism is 45 °.The seamed edge of the similar triangular prism has carried out chamfered and the class
The side of Quasi tri-prism is the cambered surface protruded to outside prism.No matter why the handle 10 of regular triangular prism structure can make toothbrush user
Hold toothbrush handle, relative orientation of the toothbrush handle in palm be it is constant, in conjunction with the habit that human body is brushed teeth, when brush head is flat
Side before face and regular triangular prism is in 45 ° of angles, when brushing teeth, it is easier to so that kept between bristle and tooth close to 45° angle,
Close to the method for brushing teeth of Pasteur's brushing.
The brush head and the handle can be structure as a whole also as Detachable connection structure, preferably removably connect
Mode is connect, which can more save use cost, the more convenient replacement head toothbrushes of energy.The case surface of the handle is from upper past
Lower extension is provided with tread plate, and the tread plate tool effectively prevents handle from sliding from palm.
