Title:
ＵＶ ＬＥＤを使用した携帯式クリーニング歯ブラシケース及び消毒滅菌方法
Document Type and Number:
Japanese Patent JP7036841
Kind Code:
B2
Abstract:
Disclosed are a movable clean toothbrush case (1) using a UV LED, and a disinfection and sterilization method therefor. A first PCB (21) is installed inside the toothbrush case (1), and one end of the first PCB (21) is perpendicularly connected to a second PCB (22) in a manner of being inserted into same; the other end of the second PCB (22) has a battery (23) installed thereat; the end at which the battery (23) is installed of the second PCB (22) is provided with a first overhead spring (41), an opposite end of the first overhead spring (41) is provided with a second overhead spring (42), the battery (23) is sandwiched and installed between the first overhead spring (41) and the second overhead spring (42), and the second overhead spring (42) and the second PCB (22) are connected by means of a wire (5); and an LED (6) covers the first PCB (21), and several groups of switch assemblies (71, 72) are installed on the second PCB (22). The method comprises: when a top cover (14) is closed, owing to the principle of homopolar repulsion, a magnet (145) on the top cover (14) pressing a magnet (723) in the switch assembly (72) on the second PCB (22) downwards, the magnet (723) in the switch assembly (72) and a PC plastic cover (721) sliding downwards in a concave hole on the toothbrush case (1) so as to compress a telescopic column (724) of a switch and then connect the switch assembly (72), a light-shielding cover (8) shielding UV light, and the second PCB (22) driving the LED (6) to emit light so as to perform disinfection and sterilization; and when the top cover (14) is open, the pressure on the magnet (723) in the switch assembly (72) on the second PCB (22) being released, the telescopic column (724) of the switch, owing to its own elasticity, pushing the magnet (723) in the switch assembly (72) and the PC plastic cover (721) to slide upwards in the concave hole on the toothbrush case (1) so same revert to the original position, thus disconnecting the switch assembly (72), the second PCB (22) driving the LED (6) to stop emitting light, and a disinfection and sterilization operation stopping.
