[0018] 2. The LED of the present invention is placed on the first PCB board, and the light-transmitting board is attached to the edge of the LED position of the first LED board of the UV LED housing, so that water and foreign matter cannot enter the LED, and LED light illuminates the interior better.

[0019] 3. Due to the LED working 吋, the emitted UV light will hurt the human skin and eyes. For safety reasons, prevent the top cover from being closed completely, and the magnet is pressed off, so that the LED is not closed. The invention starts to illuminate and damages the skin and eyes of the person. The present invention particularly provides a light-shielding cover. When the above situation occurs, the light-shielding cover can block the UV light and prevent the UV light from directly illuminating the human skin and the eye damage. And after the light-shielding cover is removed, the first closed telescopic column on the second PCB board under the light-shielding cover will protrude due to the loss of the pressure of the magnet, thereby breaking the LED power supply and simultaneously functioning safely. Similarly, when someone hits the top cover, the second telescopic column on the second PCB board will protrude due to the loss of the magnet pressure, thereby breaking the LED power supply, that is, only the light-shielding cover is placed on the toothbrush box. When the top cover is closed, the LED will emit UV light, and the toothbrush will be automatically cleaned.
