When the feeling of electric shock is changed according to the change of the electric current, the user feels psychologically anxious, and there is a problem in that a smooth treatment cannot be performed because a feeling of rejection to the electric potential treatment device may occur.

The above term may be used only for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, a 'first component' may be referred to as a 'second component', and similarly, a 'second component' may also be referred to as a 'first component'. can Also, the singular expression includes the plural expression unless the context clearly dictates otherwise.

이하, 도면을 참조하여 본 발명의 다양한 실시 예가 안내하는 본 발명의 구성과 그 구성으로부터 비롯되는 효과에 대해 살펴본다.Hereinafter, the configuration of the present invention guided by various embodiments of the present invention and effects resulting from the configuration will be described with reference to the drawings.
도 1은 본 발명의 바람직한 어느 실시 예에 따른 전위 치료 장치의 전격 방지 회로의 회로도이다.1 is a circuit diagram of an electric shock prevention circuit of a potential therapy device according to a preferred embodiment of the present invention.
본 발명의 전격 방지 회로(100)는 전원 입력부(110), 변압부(120), 출력 저항(130, 132), 스위치부(140) 및 출력부(150)로 구성된다.The electric shock prevention circuit 100 of the present invention includes a power input unit 110 , a transformer 120 , output resistors 130 and 132 , a switch unit 140 , and an output unit 150 .
전원 입력부(110)에는 교류 전원이 입력되어 변압부(120)의 입력 탭으로 전달된다.AC power is input to the power input unit 110 and transferred to the input tap of the transformer 120 .
변압부(트랜스, 120)는 교류 입력 전압을 전위 치료 장치에 필요한 전압으로 변환한다. 이를 위해 변압부(120)는 각각 출력 전압이 다른 복수의 탭으로 구성된다.The transformer (transformer) 120 converts the AC input voltage into a voltage required for the potential treatment device. To this end, the transformer 120 includes a plurality of taps each having different output voltages.
변압부(120)의 복수의 출력 탭은 스위치부(140)에서 선택되어 출력부(150)로 전달됨으로써 사용자는 전위 치료를 받는다.The plurality of output taps of the transformer 120 are selected by the switch unit 140 and transmitted to the output unit 150 , so that the user receives potential treatment.
이때 출력 전압이 사용자에게 그대로 전달되면 사용자가 느끼는 전기 충격(전격)이 크므로 출력을 제한하기 위한 출력 저항(130, 132)이 필요하다.At this time, when the output voltage is delivered to the user as it is, the electric shock (electric shock) felt by the user is large, so the output resistors 130 and 132 for limiting the output are required.
그런데 이 전격감은 변압부(120)의 출력 전압의 크기에 따라 달라질 수밖에 없으므로 전압 변화에 따른 전격감을 최소화할 필요가 있다. 따라서 출력 저항(130, 132)는 변압부(120)의 출력 탭의 전압에 비례하게 설정할 수 있다.However, since this feeling of lightning is inevitably changed according to the magnitude of the output voltage of the transformer 120, it is necessary to minimize the feeling of electric shock caused by the voltage change. Accordingly, the output resistors 130 and 132 may be set in proportion to the voltage of the output tap of the transformer 120 .
변압부(120)의 출력 탭의 전압이 클수록 출력 저항(130, 132)의 저항 값을 크게 설정하면 사용자에게 전달되는 전류는 비슷하게 될 것이므로 전압 변화에 따른 전격감 변화를 적게 느끼게 되기 때문이다.This is because, as the voltage of the output tap of the transformer 120 is increased, if the resistance values of the output resistors 130 and 132 are set to be large, the current delivered to the user will be similar, so that the change in the electric shock according to the voltage change is less felt.
또는 변압부(120)의 출력 전압의 비와 출력 저항(130, 132)의 비가 동일하도록 설정할 수 있다. 출력 전압의 비와 저항의 비가 같으면 전류는 전압을 저항으로 나눈 값이므로 모든 출력 탭에서의 출력 전류가 동일하게 될 것이다. 따라서 출력 전압에 따른 전격감이 동일해지므로 사용자의 불안감을 해소할 수 있다.Alternatively, the ratio of the output voltage of the transformer 120 and the ratio of the output resistors 130 and 132 may be set to be the same. If the ratio of the output voltage to the ratio of the resistance is the same, the current is the voltage divided by the resistance, so the output current at all output taps will be the same. Therefore, the feeling of electric shock according to the output voltage becomes the same, so that the user's anxiety can be eliminated.
도 2는 본 발명의 바람직한 다른 실시 예에 따른 전위 치료 장치의 전격 방지 회로의 회로도이다.Figure 2 is a circuit diagram of the electric shock prevention circuit of the electric potential therapy device according to another preferred embodiment of the present invention.
본 발명의 다른 실시 예에 따른 전격 방지 회로(200)는 전원 입력부(210), 변압부(220), 출력 저항(230, 232), 스위치부(240), 출력부(250) 외에 전압 측정부(260)와 입력 스위치부(270) 및 제어부(280)를 더 포함할 수 있다.In addition to the power input unit 210 , the transformer 220 , the output resistors 230 and 232 , the switch unit 240 , and the output unit 250 , the electric shock prevention circuit 200 according to another embodiment of the present invention includes a voltage measuring unit. 260 and an input switch unit 270 and a control unit 280 may be further included.
변압부(220)의 출력 탭의 출력 전류를 일정하게 하기 위해 출력 저항(230, 232)의 저항 값을 설정하더라도 전원 입력부(210)의 전압이 불안정하다면 사용자가 느끼는 전격감이 달라질 수 있다. 변압부(220)는 입력 탭의 전압을 기준으로 출력 탭으로 전압을 변환하므로 입력 전압에 따라 안정적이지 못할 수 있기 때문이다.Even when the resistance values of the output resistors 230 and 232 are set in order to make the output current of the output tap of the transformer 220 constant, if the voltage of the power input unit 210 is unstable, the user's feeling of electric shock may vary. This is because the transformer 220 converts the voltage to the output tap based on the voltage of the input tap, and thus may not be stable depending on the input voltage.
따라서 전압 측정부(260)에 의해 전원 입력부(210)의 전압을 측정한 후 측정한 전압에 의해 제어부(280)에서 입력 스위치부(270)의 스위칭 듀티(Duty)를 조절함으로써 입력 전압을 일정하게 유지할 수 있다.Therefore, after measuring the voltage of the power input unit 210 by the voltage measuring unit 260, the control unit 280 adjusts the switching duty of the input switch unit 270 by the measured voltage to make the input voltage constant. can keep
이를 위해 전압 측정부(260)는 저전압 변압기로 입력 전압을 변환하고 이를 다시 풀브릿지(Full-Bridge) 정류기로 정류한 다음 저항을 이용하여 전압을 분압할 수 있다.To this end, the voltage measuring unit 260 may convert the input voltage with a low voltage transformer, rectify it again with a full-bridge rectifier, and then divide the voltage using a resistor.
제어부(280)는 전압 측정부(260)에서 분압된 입력 전압을 측정하여 입력 전압의 안정성을 측정하고 그에 따라 입력 스위치부(270)의 스위칭 듀티를 제어함으로써 변압부(220)의 출력 전압을 일정하게 유지할 수 있다. 이를 위해 제어부(280)는 하나 이상의 프로세서 및 메모리를 포함하여 스위치부(270)의 스위칭 듀티를 제어한다.The control unit 280 measures the input voltage divided by the voltage measurement unit 260 to measure the stability of the input voltage, and accordingly controls the switching duty of the input switch unit 270 to set the output voltage of the transformer 220 constant. can keep it To this end, the control unit 280 controls the switching duty of the switch unit 270 including one or more processors and memories.
도 3은 본 발명의 바람직한 또 다른 실시 예에 따른 전위 치료 장치의 전격 방지 회로의 회로도이다.3 is a circuit diagram of an electric shock prevention circuit of a potential therapy device according to another preferred embodiment of the present invention.
본 발명의 또 다른 실시 예에 따른 전격 방지 회로(300)는 전원 입력부(310), 변압부(320), 출력 저항(330, 332), 스위치부(340), 출력부(350) 외에 전압 측정부(360)와 입력 스위치부(370) 및 제어부(380)를 더 포함할 수 있다.The electric shock prevention circuit 300 according to another embodiment of the present invention measures voltage in addition to the power input unit 310 , the transformer 320 , the output resistors 330 and 332 , the switch unit 340 , and the output unit 350 . It may further include a unit 360 , an input switch unit 370 , and a control unit 380 .
도 2의 예와 달리 도 3의 예에서는 전압 측정부(360)를 변압부(320)의 출력 탭에 배치할 수 있다.Unlike the example of FIG. 2 , in the example of FIG. 3 , the voltage measuring unit 360 may be disposed on the output tab of the transformer 320 .
전압 측정부(360)는 저항과 포토 트랜지스터로 구성되어 출력 전압을 측정할 수 있다.The voltage measuring unit 360 may include a resistor and a phototransistor to measure an output voltage.
제어부(380)는 하나 이상의 프로세서 및 제어부로 구성되어 전압 측정부(360)의 전압에 의해 입력 스위치부(370)의 스위칭 듀티를 제어할 수 있다. 따라서 변압부(320)는 입력 스위치부(370)의 스위칭 듀티 제어에 의해 일정한 출력 전압을 출력할 수 있고 출력 저항(330, 332)에 의해 출력 전류가 일정하게 조절되므로 사용자는 전압 변화에 따른 전격감의 변화를 느낄 수 없는 효과가 있다.The control unit 380 may include one or more processors and a control unit to control the switching duty of the input switch unit 370 according to the voltage of the voltage measurement unit 360 . Therefore, the transformer 320 can output a constant output voltage by the switching duty control of the input switch 370 and the output current is constantly adjusted by the output resistors 330 and 332 , so that the user can use the electric current according to the voltage change. There is an effect that you cannot feel the change in the senses.
도 4는 본 발명의 바람직한 또 다른 실시 예에 따른 전위 치료 장치의 전격 방지 회로의 회로도이다.4 is a circuit diagram of an electric shock prevention circuit of a potential therapy device according to another preferred embodiment of the present invention.
본 발명의 또 다른 실시 예에 따른 전격 방지 회로(400)는 전원 입력부(410), 변압부(420), 출력 저항(430, 432), 스위치부(440), 출력부(450) 외에 교류-직류 컨버터부(460) 및 인버터부(470)를 더 포함할 수 있다.In addition to the power input unit 410, the transformer 420, the output resistors 430 and 432, the switch unit 440, the output unit 450, the AC- It may further include a DC converter unit 460 and an inverter unit 470 .
변압부(420)의 출력 전압은 전원 입력부(410)의 입력 전압에 좌우된다. 따라서 전원 입력부(410)의 입력 전압을 안정시키면 변압부(420)의 출력 탭의 출력 전압 역시 안정될 수 있다.The output voltage of the transformer 420 depends on the input voltage of the power input unit 410 . Accordingly, when the input voltage of the power input unit 410 is stabilized, the output voltage of the output tap of the transformer 420 may also be stabilized.
이를 위해 교류-직류(AC-DC) 컨버터부(460)와 인버터부(470)를 이용하여 전압을 안정시킬 수 있다.To this end, the voltage may be stabilized using the AC-DC converter unit 460 and the inverter unit 470 .
교류-직류 컨버터부(460)에 의해 직류로 변환된 전력은 인버터부(470)를 통해 다시 교류로 변환된다. 이 때 인버터부(470)는 정해진 일정한 출력 전압으로 교류를 생성하기 때문에 변압부(420)의 입력 전압을 안정시킬 수 있는 것이다.The power converted into DC by the AC-DC converter unit 460 is converted back into AC through the inverter unit 470 . At this time, since the inverter unit 470 generates an alternating current with a predetermined constant output voltage, it is possible to stabilize the input voltage of the transformer unit 420 .
변압부(420)의 출력 전압은 출력 저항(430, 432)에 의해 동일한 전류로 변환되므로 사용자는 출력 전압에 따른 전격의 변화를 감지하지 못하고 따라서 전격의 변화에 의해 느끼는 불안감을 방지할 수 있다.Since the output voltage of the transformer 420 is converted into the same current by the output resistors 430 and 432 , the user does not sense the change in the electric current according to the output voltage, and thus it is possible to prevent the anxiety felt by the change in the electric current.
도 5는 본 발명의 바람직한 또 다른 실시 예에 따른 전위 치료 장치의 전격 방지 회로의 회로도이다.5 is a circuit diagram of an electric shock prevention circuit of a potential therapy device according to another preferred embodiment of the present invention.

It may further include a unit 560 and a control unit 570 .
전압 측정부(560)는 전원 입력부(510) 또는 변압부(520)의 출력 탭의 전압을 측정할 수 있다.The voltage measuring unit 560 may measure the voltage of the output tap of the power input unit 510 or the transformer 520 .
제어부(570)는 하나 이상의 프로세서 및 메모리를 포함할 수 있다. 제어부(570)는 측정한 전압에 따라 변압부(520)의 출력 전류를 조절하게 된다. 출력 전류는 출력 저항(530, 532)의 저항 값을 조절함으로써 조절될 수 있다.The controller 570 may include one or more processors and memories. The controller 570 adjusts the output current of the transformer 520 according to the measured voltage. The output current may be adjusted by adjusting the resistance values of the output resistors 530 and 532 .
따라서 출력 저항(530, 532)은 가변 저항으로 이루어질 수 있다. 가변 저항에 의해 저항값을 조절함으로써 변압부(520)의 출력 전류를 일정하게 조절하는 것이 가능하고 따라서 사용자는 전격감 변화에 따른 불안감을 느끼지 않을 수 있는 것이다.Accordingly, the output resistors 530 and 532 may be formed of variable resistors. By adjusting the resistance value by the variable resistor, it is possible to constantly adjust the output current of the transformer 520 , and thus the user may not feel anxious due to the change in the feeling of electric shock.
이상과 같은 본 발명의 전격 방지 회로에 따르면 전위 치료 장치의 출력 전압 변화에 따른 전격감을 일정하게 유지함으로써 갑작스런 전격감 변화에 따른 사용자의 불안을 방지할 수 있는 효과가 있다.According to the electric shock prevention circuit of the present invention as described above, there is an effect that can prevent the user's anxiety according to the sudden change in the electric shock by constantly maintaining the electric shock according to the output voltage change of the electric potential treatment device.
