Abstract

A circuit for controlling a motor of a power toothbrush operated by several steps is provided to improve a speed selecting function of the motor in the power toothbrush. A circuit for controlling a motor of a power toothbrush operated by several steps includes a MCU, a DC-DC converter, a MOSFET, and a plurality of resisters. The MCU, the DC-DC converter, and the MOSFET are used in the circuit. The plurality of resisters are used in an output side of the circuit. Output voltage rate is feedback to a measuring converter so as to output many kinds of voltage according to the number of clicks. When the MCU turns on by a first click, a signal OUT1 drives the DC-DC converter. The output voltage is set by a feedback signal of the voltage rate between resister R2 and R3. On a second click, a signal OUT2 lets a R3 ground. On a third click, a signal OUT3 has a R4 ground. The output voltage in the converter increases as voltage applied to a FB is decreased.

Description

전동칫솔 모터 속도 다단계 제어회로.{omitted} Electric toothbrush motor speed multi-stage control circuit. {Omitted}

[도1] 모터 속도 다단계 제어회로의 구성 회로도면. [1], the motor speed configuration circuit diagram of a multi-stage control circuit.

[도2] (A)는 사용 MCU 의 Sequence 도면. [Fig. 2] (A) is a view of the Sequence using MCU.

(B)는 모터쪽 OUT 의 출력전압 파형도. (B) shows the output voltage waveform of the motor-side OUT.

현재 까지는 전동칫솔의 속도를 여러 종류의 속도로 바꾸어 가면서 사용할려고 하지 않았다. Until now not going to use trying to change the speed of an electric toothbrush with different kinds of speed. 그러나 전자공학의 발달로 DC-DC Converter 가 활발히 개발됨으로써 이를 응용한 최첨단 전동칫솔을 개발케 된 것이다. But by being actively developed the DC-DC Converter With the development of electronics is the Kane developed a state-of-the-art electric toothbrush this application.

전동칫솔은 내부에 직류 저전압 소형 정류자 모터와 직류전원 즉 BTTERY를 장착하여 그 모터의 구동력으로 칫솔을 움직여 칫솔질을 하게끔 구성되어 있다. Electric toothbrush is composed hagekkeum brushing by moving the brush to the driving force of the motor equipped with a low-voltage direct-current commutator motor and a DC power supply that is compact BTTERY therein. 현재까지의 전동칫솔은 고정된 속도로 가동하게끔 제작되어 전혀 사용자가 속도를 선택사용 할 수가 없다. Electric toothbrush to the current is produced hagekkeum movable at a fixed speed can not be used at all the user selects the speed. 그러나 이번 발명희로를 장착 이용하면 설정된 다단계속도 안에서 사용자가 선택 사용할 수 있어 한층 편리하게 전동칫솔을 쓸 수 있게 된다. However, it is possible by using this invention mounted in huiro set multi-speed users can write it more convenient to use an electric toothbrush choice. 즉 한층 고급의 전동칫솔을 제작 보급함이 그 목적이다. That is further advanced manufacturing bogeupham of the electric toothbrush is that purpose.

[도1] 의 MCU에서 SW 가 클릭되어(1st) ON 되면 OUT1 이 DC-DC Converter 를 가동시키고 이때 출력 전압은 저항 R2와 R3 사이의 전압비를 FB 받아서 설정되고 두 번쩨 클릭되면(2nd) OUT2의 신호가 TR3을 통하여 R3을 접지시키게 되고 이때 FB에 걸리는 전압비는 R1과 R2,R3병열저항값 사이의 전압이 걸리게 되어 출력전압은 상승 하게된다. Is SW clicks on an MCU of Fig. 1] (1st) ON when OUT1 is operating the DC-DC Converter and wherein the output voltage of when the set receives FB the voltage ratio between the resistors R2 and R3 and then double beonjje (2nd) OUT2 voltage ratio signal is thereby ground the R3 through TR3 this time it takes to take FB is the voltage between R1 and R2, R3 byeongyeol resistance value output voltage is increased. 또 세 번쩨 클릭하면(3rd) OUT3 에서 나오는 신호가 TR4를 통하여 R4를 접지시키고 이때 FB에 걸리는 전압비는 R1과 R2,R3,R4병열저항값 사이의 전압이 FB에 걸리게 되고 이때 출력 전압은 더욱 상승케 된다. In three beonjje click to the signal from the OUT3 (3rd) voltage ratio grounded R4 through TR4 and case applied to the FB is the voltage between R1 and R2, R3, R4 byeongyeol resistance being caught by the FB wherein the output voltage is further elevated Kane is. 여기에서는 FB 에 걸리는 전압이 낮아질수록 OUT 출력전압이 상승하는 Converter 를 사용 하였다. Herein The lower the voltage across the FB was used to OUT Converter output voltage rises.

여기서 MOSFET는 CONVERTER에서 나오는 PWM 신호를 받아서 OUT으로 전류를 보내게 되는대 몇Amp의 전류를 보낼려면 내부저항이 가장적은 TR 을 사용 해야 하기 때문에 TR1과 TR2 는 MOSFET를 사용 하였다. The MOSFET receives the PWM signal from the CONVERTER To send a current of about a few Amp that send an electric current to OUT because you have an internal resistance using the fewest TR TR1 and TR2 was used as a MOSFET.

[도2] (A)를 보면 MCU Switch sequence 도로 1st Click 하면 OUT1이 무조건 5th Click 할 때까지 ON(H) 출력되고 다시 2nd Click하면 OUT1이 ON상태에서 OUT2가 ON 되고 다시 3rd Click 하면 OUT1, OUT2 가 모두 ON상태 하에서 OUT3 가 ON 된다. [Fig. 2] (A) a look MCU Switch sequence road when 1st Click OUT1 unconditionally 5th When Click to ON (H) output is again 2nd Click until OUT1 is OUT2 is ON in the ON state again 3rd Click OUT1, OUT2 the OUT3 under the ON state are both ON. 또 4th Click 하면 OUT1은 ON인 상태에서 OUT2, OUT3가 함께 ON-OFF 깜박이 동작으로 바뀌게 되고 5th Click 하면 모든 동작이 멈추게 된다. Also when 4th Click OUT1 is shifted to ON-OFF flashing operation with the OUT2, OUT3 in the ON state when 5th Click stops all operations. (여기서 ON 이란 H Level 을 뜻 한다.) (Wherein means is ON H Level.)

어떤 동작이나 5th click 하면 멈추게 된다. If any action or 5th click stops.

(B) OUT 도면을 보면 1st, 2nd, 3rd 까지 의 출력전압은 점선으로 표시하였 고 4th Click 때의 출력전압은 실선으로 표시 하였다. (B) In the drawings OUT output voltage to the 1st, 2nd, 3rd and 4th time was the output voltage of the Click was indicated by a broken line is shown in solid lines.

디지털 전자의 발달로 좋은 부품 IC 가 있어 이를 전동칫솔에 까지 적용시켜 우리 인간의 생활을 더욱 윤택 하게 하여 주고 있다. There is a good IC component to the development of digital electronics to give it to them to apply to the electric toothbrush more prosperous our human life. 이제는 인간 수명의 연장과 함께 치아의 수명도 연장 하여 생을 종료 할때 까지 건치로 즐거움을 유지하여야 함으로 한층 승급된 칫솔을 요구하게 되고 이에 발마추어 속도 다단계 제어회로를 발명 하여 전동칫솔에 적용 사용코저 한다. Now and require a further promoted by should maintain the pleasure with geonchi and ends when the life is extended also the tooth life toothbrush with the extension of human life thereto to machueo speed invention a multi-stage control circuit kojeo use applied to the electric toothbrush do.
