본 고안은 훠니스(FURNACE) 제품의 전자펌프에서 연료가 완전 소모되는 것을 사전에 방지하기 위한 유량검출 및 안전장치에 관한 것으로, 특히 전자펌프에서 연료가 완전 소모되기 전에 이를 감지하여 제품의 동작을 정지시키고 급유램프(LED)로 연료탱크의 연료유무를 표시하기 위한 것이다.The present invention relates to a flow rate detection and safety device to prevent fuel from being completely consumed in an electronic pump of a FURNACE product, and in particular, detects the operation of the product by detecting it before the fuel is completely consumed in the electronic pump. It is to stop and display the fuel tank in the fuel tank with LED lamp.

종래의 안전장치회로에는 연료 검지 기능이 없어서 연료가 완전히 소모될 때 비로소 점검램프가 점등되었다.The conventional safety device circuit does not have a fuel detection function, and thus the inspection lamp is turned on only when the fuel is completely consumed.

따라서 점검램프가 점등된 것 만으로는 제품기능에 이상이 있는지 아니면 연료가 없는지를 쉽게 구별할 수 없었고 사용자가 연료가 없다는 것을 판단한 후에 연료를 재급유해서 제품을 동작시킨 다음에는 반드시 전자펌프의 공기뽑기 작업을 해야 했으며, 또한 숙달이 되지 않은 사용자가 사용시 공기뽑기 작업을 여러번 되풀이하게 되므로 제품의 수명을 단축시키는 한편 이로인해 전자펌프의 고장을 일으키는 요인이 되었다.Therefore, it was not possible to easily distinguish whether the product functioned abnormally or that there was no fuel by only turning on the check lamp.After deciding that the user was out of fuel, the user must re-fuel the fuel before operating the product. In addition, the unskilled user repeated the air extraction several times during use, which shortened the life of the product and caused the failure of the electronic pump.

본 고안은 이와같은 결점을 해소하기 위하여 연료가 전자펌프에서 완전 소모되기 전에 이를 감지하여 제품의 동작을 정지시키는 동시에 급유램프가 점등되어 연료탱크에 연료가 없다는 것을 사용자가 쉽게 알수 있도록 안출된 것으로 이를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.In order to solve this problem, the present invention detects the fuel before it is completely consumed by the electronic pump and stops the operation of the product. At the same time, the refueling lamp is turned on so that the user can easily know that the fuel tank is free. When described in detail based on the accompanying drawings as follows.

즉, 저항(R1, R2), 대진소화장치(A)를 OP 앰프의 반전단자(-)에 접속시키고, 저항(R3, R4), 과열방지장치(B)를 OP 앰프의 비반전단자(+)에 접속시키며, OP 앰프의 출력단에 트랜지스터(Q1-Q3), 저항(R5-R9), 다이오드(D1-D3), 점검램프(LED1)를 접속시켜 상기 트랜지스터(Q1-Q3)가 상호 동작 되도록 하고 트랜지스터(Q3)의 콜렉터측에 전자펌프 및 부하전원 공급선(가)를 접속시켜 구성되는 통상의 유량 안전장치 회로에 있어서, 트랜지스터(Q4), 저항(R11, R12), 급유램프(LED2) 및 스위치(H)로 구성되는 유량검출부(라)를 상기 OP 앰프의 입력단에 접속시키고, 상기 스위치(H)와 기름여과기(D)의 리드 릴레이(REED RELAY)(G)를 유량의 변동에 따라 연동 동작되도록 접속시켜 구성된 것이다.That is, the resistors (R 1 , R 2 ) and the macro-extinguishing device (A) are connected to the inverting terminal (-) of the op amp, and the resistors (R 3 , R 4 ) and the overheat prevention device (B) are non-op amps. Connect the inverting terminal (+), and connect the transistors (Q 1 -Q 3 ), resistors (R 5 -R 9 ), diodes (D 1 -D 3 ), and check lamp (LED 1 ) to the output terminals of the OP amplifier. In the conventional flow safety circuit, which is configured by allowing the transistors Q 1 to Q 3 to operate with each other and connecting the electron pump and the load power supply line A to the collector side of the transistor Q 3 , the transistor Q 4 is provided. ), A flow rate detecting unit (D) consisting of a resistor (R 11 , R 12 ), an oil supply lamp (LED 2 ), and a switch (H) is connected to an input terminal of the OP amplifier, and the switch (H) and an oil filter (D) are connected. It is configured to connect the reed relay (G) of () to the interlocking operation in accordance with the flow rate change.

미설명 부호 C는 필터, E는 기름여과기 공기배출구에 결합된 나사이다.C is a filter, E is a screw connected to the oil filter air outlet.

이와같이 구성된 본 고안의 작용효과를 제3도에 의하여 설명하면 다음과 같다.Referring to Figure 3 illustrates the effects of the present invention configured as described above.

먼저 기름여과기(D)내에 있는 연료가 점선부근까지 내려오면 기름여과기(D)내에 설치되어 연료의 변동에 따라 이동되는 자석(F)이 부력에 의해 리드 릴레이(G) 위치로 내려오게 되므로 리드릴레이(G)가 도통되며 따라서 연동되어 동작하는 스위치(H)도 도통되다.First, when the fuel in the oil filter unit (D) comes to the vicinity of the dotted line, the reel relay is installed in the oil filter unit (D) and moved according to the fluctuation of the fuel. (G) is turned on, so that the switch (H) which is interlocked and operated is also turned on.

스위치(H)가 도통되면 저항(R11)에 인가되는 전압에 의하여 트랜지스터(Q4)가 도통되어 급유램프(LED2)가 점등되며, OP 앰프의 비반전 단자(+)에 Vcc1가 인가되므로 OP 앰프의 출력은 하이(HIGH)가 되어 트랜지스터(Q1)가 도통된다.When the switch (H) continuity resistance is conductive is by the voltage transistor (Q 4) is applied to (R 11) lights up the oil supply lamp (LED 2), applied with the Vcc 1 to the non-inverting terminal (+) of the OP amplifier Therefore, the output of the OP amplifier becomes HIGH, and transistor Q 1 is conducted.

여기서, OP 앰프의 입력단 전압을 스위치(H), 대진소화장치(A)가 차단상태에 있을 때 나, 다의 전위는 나＞다로 설계하여야 한다.Here, when the switch (H) and the macro-extinguishing device (A) are in the blocking state, the input terminal voltage of the OP amplifier should be designed as B> C.

만약, 스위치(H)가 차단되었을 때나 점의 전위는 저항(R11)과 저항(R2)이 병렬 연결되어 있으므로가 된다.If the switch (H) is disconnected or the potential of the dot is connected in parallel with the resistor (R 11 ) and the resistor (R 2 ) Becomes

이때, 나 점의 전위는 다 점의 전위보다 적게되도록 저항(R11)을 설정한다.At this time, the resistance R 11 is set so that the potential of the dot is less than the potential of the multiple points.

한편, 트랜지스터(Q1)가 도통되면 트랜지스터(Q2)도 도통되어 점검램프(LED1)가 점등되고 트랜지스터(Q3)는 차단되도록 전자 펌프 및 부하전원 공급선 (가)에 전원이 차단되어 제품은 동작을 중지하게 된다.On the other hand, when the transistor Q 1 is turned on, the transistor Q 2 is also turned on so that the check lamp LED 1 is turned on and the transistor Q 3 is cut off so that the power is cut off from the electronic pump and the load power supply line (a). Will stop the operation.

이와같이 본 고안장치는 유량이 적정선 이하로 내려가면 이를 감지하는 유량 검출장치에 의하여 급유램프가 점등되고 이어서 점검 램프가 점등되는 동시에 제품의 동작이 중지되므로 사용자가 원료 탱크속에 연료가 없다는 것을 쉽게 파악하여 전자램프의 완전 연료 소모를 사전에 방지할 수 있을 뿐만 아니라 연료급유 후 사용자가 전자펌프의 공기뽑기 작업을 해야했던 불편함이 없어짐은 물론 전자펌프의 수명 곧 제품의 수명을 오래 유지할수 있으며 단지 기름여과기에 있는 공기만 제어하면 되는 사용상의 편의를 주는 유익한 특징이 있는 것이다.In this way, the device is designed so that the oil supply lamp is turned on by the flow detection device that detects when the flow rate falls below the proper line, and then the inspection lamp is turned on and the product is stopped. Not only can the fuel consumption of the electronic lamp be completely prevented in advance, but also the inconvenience of the user having to purify the air of the electronic pump after refueling is eliminated, and the life of the electronic pump can be maintained for a long time. There is an advantageous feature that allows the user to control only the air in the filter.
