전동칫솔의 종류를 분류 해보면If you sort the type of electric toothbrush

1; 충전식 과 건전지식.(공급전원으로 분류)One; Rechargeable and battery powered (classified as power supply)

2; 스윙식. 로타리식. 버스식.(칫솔의 움직임방식으로 분류)2; Swing type. Rotary type. Bus type (classified by toothbrush movement)

3; 모터구동식. 진동기구동식.(칫솔을 움직이는 동력으로 분류)3; Motor driven type. Vibration driven type (classified as moving power of toothbrush)

이상 3개 분야로 분류 할수 있는데 종래까지의 이들 모든 분야는 전부 고정속도 구동으로 생산 되어 판매 유통 되고 있다. 이들 고정속도 전동칫솔은 한번 매입한 뒤에는 만족 불만족 여하를 떠나서 폐기 할 때까지 사용자의 취향과 관계없이, 또는 치아의 길이, 폭, 형태, 잇몸의 상태 등과는 관계없이 사용하게 됨으로 결국 양치질로 인한 치아 및 치주의 변형 등 부작용이 없다고 할 수없다. 최근 모든 가전 용품이 디지털화함에 따라 전동칫솔도 디지털 전자회로를 적용 사용함으로 해서 더좋은 그리고 사용자가 더욱 편리하고 안전하며 편하게 쓸 수 있는 최첨단 전동칫솔로 생산 방향이 바뀌고 있는 것이 최근의 상항이며 우리도 이방향의 기술을 최대한 이용하는 새로운 기술로 최첨단 전동칫솔을 개발해야 한다.It can be classified into three fields as above. All these fields until now are all produced and sold in fixed speed drive. These fixed-speed electric toothbrushes can be used regardless of the user's taste or the length, width, shape, and gum condition of the teeth until they are discarded after dissatisfaction and discarded. And there is no side effect such as periodontal deformation. As all household appliances have been digitized in recent years, electric toothbrushes have been applied with digital electronic circuits, and the direction of production is changing with the latest electric toothbrushes, which are better, more convenient, safer and more convenient for users. A new technology that takes full advantage of the company's technology needs to develop state-of-the-art electric toothbrushes.

위에서 언급한 것처럼 어린이들은 치아의 길이가 짧고 잇몸이 약하므로 가능한 속도를 낮게 하여주고 청장년의 경우 치근이 튼튼하고 치아의 길이도 완전히 성장 하였으며 잇몸도 건강하므로 속도를 높게 사용 하는 것이 양치질에 도움을 주는 동시에 치주 마사지를 해주는 효과도 볼수 있다. 또 치주염 환자이거나 치아건강이 좋지 못한 사람 및 노년층의 사용자들은 중간정도의 속도로 사용함이 좋을 것이다. 즉 다단계 가변속도 전동칫솔의 필요성이 여기 있는 것 이다. 이처럼 칫솔 사용자가 자기 구강내의 환경상태와 치아상태에 맞추어 몇단계의 속도를 조정 사용 할 수 있으면 가장 효과적인 치아관리를 할 수 있게 된다. 현재까지는 이처럼 여러 종류의 속도를 사용자가 직접 선택하여 사용 하게끔 제작된 전동칫솔은 없었으므로 이 발명은 전동칫솔 로는 완전히 새로운 아이디어와 새로운 기술적 분야를 개척 하게 되는 발명이다.As mentioned above, children have shorter teeth and weaker gums, so they should be as slow as possible, and in young adults, they have strong roots, full lengths of teeth and healthy gums. At the same time, you can see a periodontal massage effect. In addition, people with periodontitis or those with poor dental health and older users should use it at moderate speed. That is why there is a need for a multi-stage variable speed electric toothbrush. In this way, if the toothbrush user can adjust the speed of several stages according to the environmental condition and the dental condition in his oral cavity, the most effective dental care is possible. Until now, since no electric toothbrush was designed to allow users to select and use various types of speeds, the present invention is an invention in which the electric toothbrush opens up a whole new idea and a new technical field.

이하 첨부된 도면에 따라 상세히 설명하겠다.Hereinafter will be described in detail according to the accompanying drawings.

[도 1]은 일반적인 모터구동식 전동칫솔의 정면도인데 여기서 (A)는 칫솔, (B)는 전동칫솔 본체, (S)는 스위치를, (D)는 LED 또는 LCD Display, 가 위치할 자리를 표시하였다.1 is a front view of a general motor-driven electric toothbrush where (A) is a toothbrush, (B) is an electric toothbrush body, (S) is a switch, (D) is an LED or LCD display, Indicated.

일반 전동칫솔에서는 (S)스위치를 누르면 전원이 ON되어 전동칫솔이 동작하 며 (A)칫솔이 설정된 고정동작(제조회사에따라- 스윙식, 버스식, 로타리식, 등등)으로 고정속도로 작동하고 다시 스위치를 누르면 전원이 OFF되어 동작이 멈추게 된다. (S)스위치는 단순 ON, OFF 동작만 하였을 뿐이다.In the general electric toothbrush, press the (S) switch to turn the power on and the electric toothbrush operates. (A) The toothbrush is operated at a fixed speed by a fixed action (depending on the manufacturer-swing type, bus type, rotary type, etc.). If you press the switch again, the power is turned off and operation stops. The (S) switch only performed ON and OFF operations.

그러나 본 발명 가변속도 전동칫솔은 (S)스위치를 누르는 회수에 따라 속도가 달라지는 다단계동작을 하게 된다. 즉 한번 누르면 저속, 두 번 누르면 중속, 세 번 누르면 고속, 네 번 누르면 고저속 교번(마사지효과), 다섯 번 누르면 정지 등등, 순차적으로 속도가 변하도록 내부에 [도2]와 같은 전자 회로를 설계 장착 하였다. [도2]에서는 2개의 IC를 사용 하였는데 하나는 MCU이고 다른 하나는 PWM DC-DC Converter 이다. 여기서 TR1과 TR2는 M(motor) 에 PWM 전류를 공급하게 되는데 이때 부하변동에 의하여 발생하는 전압변동을 상호 보완 동작 하여 균일전압을 유지케 되에 있다. 또 전압설정은 C1,R1과 R2 (또는 R3 혹은 R4 중 MCU 에 의하여 선택된)와의 분배 비율 전압을 Converter의 FB(Feed back)에 가함으로써 필요전압을 얻게 되어 있다.However, the variable speed electric toothbrush of the present invention has a multi-step operation in which the speed varies depending on the number of times the (S) switch is pressed. In other words, the electronic circuit as shown in Fig. 2 is designed so that the speed is changed sequentially by pressing once for low speed, twice for medium speed, three times for high speed, four times for high and low speed alternation (massage effect), five times for stop, and so on. Was fitted. In Figure 2, two ICs are used, one is MCU and the other is PWM DC-DC Converter. Here, TR1 and TR2 supply PWM current to M (motor). At this time, the voltage fluctuation caused by load fluctuation is complementary to maintain uniform voltage. In the voltage setting, the required voltage is obtained by applying a division ratio voltage between C1, R1 and R2 (or R3 or R4 selected by the MCU) to the converter's FB (Feed back).

TR3,TR4는 MCU의 명령에 따라 R3또는 R4를 접지 단락 하거나 또는 개방 시키기 위하여 사용 한 것 이다. R2,R3,R4는 저항값이 서로 상이하여 선택된 저항마다 전압비가 틀리게 된다. 따라서 R2,R3,R4의 선택접지가 바로 출력전압의 변화로 나타나게 된다. MCU의 출력 O1, O2, O3, 가 스위치(S)의 Push 수에따라 순차적으로 H,도는 L,로 바뀌면서 R2,R3,R4 저항을 접지시켜 여러 단계의 전압을 모터(M)에 공급하게 된다. 여기 [도2] 에서는 동작 상태의 Display를 발광 Diode LED를 사용한다고 가정한 그림으로 D1,D2,D3는 LED 이고 저항 R9,R10,R11은 LED 동작 저항 이다. LCD Display를 장착 사용시 에는 Display부 회로가 달라 질것 이다. TR3 and TR4 are used to short-circuit or open R3 or R4 by MCU command. R2, R3, and R4 have different resistance values, so that the voltage ratio is different for each selected resistor. Therefore, the selective ground of R2, R3, R4 is represented by the change of output voltage. The outputs O1, O2 and O3 of the MCU are sequentially changed to H and L according to the number of pushes of the switch S, and the R2, R3 and R4 resistors are grounded to supply voltages to the motor M. . Here, in FIG. 2, it is assumed that the LED in the operating state uses a light emitting diode LED. D1, D2, and D3 are LEDs, and resistors R9, R10, and R11 are LED operating resistors. When using LCD Display, the circuit of Display part will be different.

[도2]의 C2,C3은 전해 Condenser 이다. TR1,TR2는 MOSFET를 사용함으로써 Motor (M) 에 충분한 전류가 흘러도 TR1,TR2의 내부 저항에 의한 전압강하가 거의 없다. 이상과 같이 (M)에 공급 되는 전압을 임의로 조정하여 (M) 의 속도를 다단계로 조정설정 함으로써 Motor 에 연결되어 있는 Cam(H) 에 삽입된 칫솔의 속도를 다단계로 변속 하게끔 설계한 가변속도 전동칫솔을 발명 하였다.
이들의 동작과 배치상태를 더욱 상세히 설명하기 위하여 위선 여러종류의 전동칫솔 중에서 버스식 전동칫솔의 내부구조도면을 예로 덜어서 내부 도면을 전계 하였다. [도3] 의(가)와 (나)의 두 개의 도면에서 설명 하겠다. (가)도면은 전동칫솔의 단면도이고 (나)도면은 전동칫솔 내부의 사시도 이다. 여기서(E)는 왕복동작을 하는 Cam(H)샤프트의 고정을 위한 베어링 이고 (F)는 모터M의 축에 편심으로 고정 삽입되어 있는 CRANK이다. 캠 하우스 속의 크랭크(F)가 회전하면 캠(H)축이 자우로 왕복운동을 하게되고 여기에 삽입되어 있는 칫솔(A)가 캠의 왕복진폭에 따라 왕복운동을 하게된다. 여기서(P)는 전자회로를 구성하고 있는 PCB기판이고 (K)는 전자회로를 표시 하였다.C2 and C3 in FIG. 2 are electrolytic condenser. Because of the use of MOSFETs, TR1 and TR2 have almost no voltage drop due to the internal resistance of TR1 and TR2 even if sufficient current flows to the motor (M). Variable speed electric motor designed to change the speed of toothbrush inserted in Cam (H) connected to the motor in multiple stages by arbitrarily adjusting the voltage supplied to (M) as described above. Invented a toothbrush.
In order to explain the operation and arrangement of these in more detail, the internal drawings were drawn from the internal structure drawings of the bus-type electric toothbrush among the various types of electric toothbrushes. 3 will be described in (a) and (b). (A) The drawing is a sectional view of the electric toothbrush. (B) The drawing is a perspective view of the electric toothbrush. Here (E) is a bearing for fixing the cam (H) shaft reciprocating operation (F) is CRANK is fixedly inserted into the shaft of the motor M. When the crank F in the cam house rotates, the cam shaft H reciprocates and the toothbrush A inserted therein reciprocates according to the reciprocating amplitude of the cam. Where (P) is the PCB board constituting the electronic circuit and (K) is the electronic circuit.

이상에서 상술한바와 같이 디지털 전자회로를 적용시켜 속도를 가변 시킬 수 있다는 것은 전동칫솔 에서는 새롭게 발명한 아이디어로 전동칫솔 분야에 새로운 바람을 불어 넣을 것으로 보인다. 세계적으로 일류업체들이 치열한 기술경쟁을 하고 있는 중에도 이번 발명 같은 디지털 전자회로를 적용시켜 속도를 다단계로 변화시키는 방법은 전동칫솔 기술을 더욱 업그레이드 시키는 것으로 이 발명은 참신한 새로운 시장개척에 크게 도움을 준다고 확신한다. 세계 일류상품을 향한 발명이다.As described above, it is possible to change the speed by applying a digital electronic circuit to the electric toothbrush, which is a newly invented idea. In the midst of fierce competition among the world's leading companies, the method of applying digital electronic circuits such as this invention to change the speed in multiple stages is to upgrade the electric toothbrush technology further, convinced that this invention greatly helps to open up a new new market. do. It is an invention for world class products.
