Toothbrush

Abstract

The present invention relates to a toothbrush, comprising: a toothbrush body unit having a gripping handle and a head part coupled to the front end of the gripping handle; a bristle implanted in one area of the outer surface of the head part; a laser diode mounted on the gripping handle to emit a laser beam to the inside of the head part; a battery mounted on the gripping handle and electrically connected to the laser diode; a laser driving unit having a start switch installed on the gripping handle; a reflector installed within the head part to guide the laser beam emitted by the laser diode to the bristle; and a light-scattering member having a scattering body which is made of a transparent material and which has a laser passage hole with a cross-sectional area smaller than the illumination area of the laser beam emitted by the laser diode, and which is arranged in the toothbrush body unit to enable the laser beam emitted by the laser diode to pass through the laser passage hole and be scattered.

1 . The toothbrush is characterized to have the toothbrush stem, the toothbrush body with the head which is connected to the front of the toothbrush stem, the bristles which are tufted at the surface of the working area of the head, the laser diode which is installed in the toothbrush stem and irradiates laser towards the inside of the head, the battery which is installed in the toothbrush stem to be connected electrically to the laser diode, the laser actuator which opens and closes electrical connections between laser diode and battery depending on the operational status of the operational switch installed in the toothbrush stem and the laser diode irradiating the laser which is guided to bristles by the reflector installed in the head. It is made of transparent materials and it has the light scatter installed in the toothbrush body to recognize light scattering status of the light scattering body. Laser irradiated from the laser diode passes through the laser path way which has smaller cross sectional area than irradiating area. 
     
     
         2 . According to the  claim 1 , it is characterized that the light scatter is installed in the toothbrush body. 
     
     
         3 . According to the  claim 2 , the head of the toothbrush, which has the head body where bristles are tufted and the toothbrush stem which is the extended line of the head body and has the space for the light scatter, is able to combine or remove through the toothbrush stem connector and the light scatter and;
 The toothbrush is characterized that the light scatter is combined to the toothbrush stem to be landed in the scatter settle space.   
     
     
         4 . According to the  claim 3 ,
 The toothbrush is characterized to include another contact safety part formed from the extension of the outer surface of the light scattering body to have umbrella shape with the cooperation with the light scattering body and the light scatter.
