이하, 본 고안의 작용을 설명한다.Hereinafter, the operation of the present invention.

본 고안의 전동칫솔을 이용하여 치아를 닦고저 할 때에는 도 9의 도시와 같이 양측의 칫솔고정패널(17)에 형성된 요함부(18)에 양측 어금니가 삽입되고 치아전체가 다수의 칫솔(13)사이에 위치되도록 마우스피스를 물듯이 칫솔장착부(2)를입에 문 후, 손잡이케이스(4)에 설치된 스위치(도면에는 도시하지 않음)를 조작하여 모터(5)에 전원을 인가한다.When brushing teeth using the electric toothbrush of the present invention, as shown in FIG. 9, both molar teeth are inserted into the recesses 18 formed in the toothbrush fixing panels 17 on both sides, and the entire tooth is a plurality of toothbrushes 13. The toothbrush mounting portion 2 is held in the mouth as if the mouthpiece is positioned therebetween, and then a power is supplied to the motor 5 by operating a switch (not shown) installed in the handle case 4.

모터(5)에 전원이 인가되면, 모터(5)의 회전축과 연결된 구동부(1)내의 평기어(6)들이 회전하면서 이에 연결된 칫솔구동축(8)과 원형칫솔구동축(7)이 회전하는 것이다.When power is applied to the motor 5, the toothed gear drive shaft 8 and the circular toothbrush drive shaft 7 connected thereto rotate while the spur gears 6 in the driving unit 1 connected to the rotary shaft of the motor 5 rotate.

양측의 원형칫솔구동축(7)이 회전하면서 양측 어금니 사이에 위치된 원형칫솔(14)을 회전시켜 어금니의 상하면을 닦아내게 되는 것이다.As the circular toothbrush driving shaft 7 on both sides rotates, the upper and lower surfaces of the molars are wiped by rotating the circular toothbrush 14 positioned between the molars on both sides.

중앙의 칫솔구동축(8)이 회전하면서 동력전달부(3)의 웜기어(15)를 일측방향으로 회전시키게 되고, 이와 연결된 양측의 웜기어(15')(15")가 동시에 회전하면서 스프링(10)으로 연결된 내,외측 및 상,하측 칫솔(13)이 동시에 회전하게 되는 것이다.As the toothbrush driving shaft 8 in the center rotates, the worm gear 15 of the power transmission unit 3 is rotated in one direction, and the worm gears 15 'and 15 "connected to both sides rotate simultaneously, and the spring 10 is rotated. Inner, outer and upper, lower toothbrush 13 is connected to be rotated at the same time.

이때, 상,하측에 설치된 칫솔(13)은 윗니의 경우 칫솔모가 상측에서 하측으로 향하도록 회전시키고, 아랫니의 경우 칫솔모가 하측에서 상측으로 회전되게 모터(5)의 회전방향을 설정하므로서, 잇몸을 보호하고 보다 깨끗하게 치아를 닦을 수 있는 것이다.At this time, the toothbrush 13 installed on the upper and lower sides rotates the bristles toward the upper side in the case of the upper teeth, and in the case of the lower teeth, sets the rotation direction of the motor 5 so that the bristles rotate from the lower side to the upper side. You can protect and clean your teeth more cleanly.

본 고안의 전동칫솔은 칫솔장착부(2)를 구성하는 고정프레임(12)이 다수의 힌지연결부(9)로 연결되어 있고, 내부에 설치된 다수의 칫솔(13) 및 원형칫솔(14)이 스프링(10)으로 연결되어 있으므로, 스프링(10)의 유연성 및 탄발력에 의해 모터(5)에 의한 회전력을 칫솔(13) 및 원형칫솔(14)에 그대로 전달할 수 있으면서도, 사용자의 치형에 따라 그 형상을 변형하여 사용할 수 있으며, 고정프레임(12)이 칫솔(13)의 회전시 입내부의 살과 접속되는 것을 차단하여 입안내부를 보호할 수 있는 것이다.In the electric toothbrush of the present invention, the fixed frame 12 constituting the toothbrush mounting portion 2 is connected by a plurality of hinge connections 9, and a plurality of toothbrushes 13 and a circular toothbrush 14 installed therein are springs ( 10), it is possible to transfer the rotational force of the motor 5 to the toothbrush 13 and the circular toothbrush 14 by the flexibility and elasticity of the spring 10 as it is, the shape according to the user's teeth Can be used to deform, it is possible to protect the mouth guide by blocking the fixing frame 12 is connected to the flesh in the mouth when the toothbrush 13 rotates.

고정프레임(12)의 내측양면에 설치된 지지대(11)는 외측 칫솔(13)이 회전시 방해를 주지 않으면서 견고히 지지하여 사용중 칫솔(13)이 유동되는 것을 방지하는 것이다.The support 11 installed on both inner sides of the fixing frame 12 is to prevent the toothbrush 13 from flowing during use by firmly supporting the outer toothbrush 13 without disturbing the rotation.
