The present invention relates to an electric toothbrush, and more particularly, to an electric toothbrush which includes a toothbrush body having a power supply unit built therein, a driving motor that receives power from the power supply unit and rotates the driving shaft, and a toothbrush handle coupled to the toothbrush body, A toothbrush according to any one of the preceding claims, wherein each said sole portion comprises a bristle shaft; And a plurality of bristles disposed at equal intervals along a circumferential direction of the bristle shaft, wherein each of the bristles is arranged in a spiral shape along a longitudinal direction of the bristle shaft, The plurality of bristles are spirally arranged on the other sole portion and are engaged with the corresponding bristles corresponding to each other to smoothly rotate the tooth surface so as to smoothly remove foreign matter caught in the gap between the tooth and the teeth.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a power toothbrush, and more particularly, to a power toothbrush capable of easily removing foreign matter in a mouth using motor power.
In general, various devices have been developed for oral health, and electric toothbrush is one of them.
By using a motor to rotate the bristles several times per minute, the electric toothbrush can perform much more brushing than when the user directly wipes his teeth.
Therefore, it is possible to easily remove foreign substances and calculus adhered to the teeth easily.
1, a conventional electric toothbrush disclosed in Registration Practical Utility Model No. 0403315 has a user's intention to perform brushing on the tooth surface, One of the two
Further, in the conventional electric toothbrush, the
In addition, since the
SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a toothbrush capable of uniformly distributing force to tooth surfaces or skin tissues.
Another object of the present invention is to make it possible to easily remove foreign matter caught in a tooth gap by using bristles of a shape having excellent scrubbing property.
It is still another object of the present invention to provide a toothbrush device and a toothbrush which are configured such that only a driving shaft connected to a toothbrush body by a driving motor rotates and a driving shaft connected to the toothbrush holder is stopped, To be reduced significantly.
According to an aspect of the present invention, there is provided a powered toothbrush comprising: a toothbrush body having a power supply unit built therein; a driving motor for receiving power from the power supply unit and rotating the driving shaft; An electric toothbrush comprising an attached toothbrush body,
Wherein each of the soled portions comprises:
Bristle shaft; And
And a plurality of bristles disposed at equal intervals along a circumferential direction of the bristle shaft,
And each of the bristles is arranged in a spiral shape along the longitudinal direction of the bristle shaft.
And the bristles formed on the pair of bristle shafts are configured to rotate in engagement with each other.
A toothbrush socket is formed at the distal end of the toothbrush handle to receive a portion of a pair of toothbrushes,
An idle gear engaged with the driving gear and rotating in a direction opposite to a rotating direction of the driving gear, and a driving gear which is engaged with the driving gear and the idle gear, And a pair of driven gears formed in the circumferential direction are accommodated.
Wherein the drive shaft has a structure in which a first drive shaft and a second drive shaft are separated from each other,
The toothbrush body is provided with a first driving shaft connected to the driving motor and protruding in the longitudinal direction from an end of the toothbrush body, a first rotor shaft having a polygonal columnar shape is connected to one end in the longitudinal direction of the first driving shaft, A second driving shaft is received in the toothbrush handle, a second rotor shaft having a polygonal columnar shape is formed at the other end of the second driving shaft, and a hollow having a polygonal columnar shape for receiving the first rotor shaft and the second rotor shaft inside And a connecting cylinder.
And a plurality of cut-away portions spaced along the circumferential direction are formed on the circumferential surface of the first rotor shaft of the connecting cylinder.
And a contact protruding portion is formed at the free end of the cutout portion so as to protrude toward the inside of the connecting cylinder.
According to the electric toothbrush of the present invention as described above, the plurality of bristles arranged in a spiral shape on one sole are spirally arranged on the other sole and are continuously rotated along the tooth surface by engaging with the corresponding bristles It has the effect of gently removing the foreign matter caught in the gap between the teeth and the teeth.
According to the present invention, when wiping the skin tissue in the oral cavity, when the skin tissue accidentally rubs between the bristles between the bristles, only the driving shaft in the toothbrush body rotates and the driving shaft housed in the toothbrush body is stopped, There is an effect that can be reduced.
In addition, according to the present invention, a pair of sole housed in the toothbrush socket can uniformly distribute the force to the upper teeth and the lower teeth, thereby improving cleaning performance as well as brushing performance.
