Summary:The present invention relates to a flow detection device comprising: a housing having an inlet and an outlet formed respectively at upper and lower ends, having a waterway formed inside, and having a combination hole formed on an outer surface; a housing cover combined with the combination hole of the housing; a switch installed on the outer surface of the housing; and a driving plate, which has a downward protruding resistance plate formed on the inner wall surface of the waterway of the housing, installed to be able to rotate. Accordingly, water moving upward through the waterway generates friction on the bottom surface of the driving plate and the resistance plate, thereby increasing the resistance of the driving plate while increasing the frictional area of water to adjust the rotating speed of the driving plate. According to the present invention, the resistance plate is formed to protrude from the bottom surface at both sides of the driving plate, so there is no risk of an interval between the waterway and the driving plate being reduced, and water is rubbed on the bottom surface of the driving plate and the resistance plate to increase friction while increasing the area of friction. Specifically, the driving plate is operated sensitively by the resistance of water and can be rotated swiftly owing to the increase of friction. Also, the flow of water can be detected accurately owing to the swift operation of the driving plate, the pressure of water supplied to the waterway can be reduced to be proportionate to the resistance of the driving plate. In addition, a flow path detection device can be installed in a pipeline having various water pressures to detect whether water flows in the pipeline, thereby improving the reliability of a product. 본 발명은 유량검지장치에 관한 것으로, 상, 하단 각각에 배출구 및 유입구를 형성하고, 내측에 수로를 형성하며, 외면에 결합홀을 형성한 하우징을 구비하고, 하우징의 결합홀에 하우징커버를 결합하며, 하우징 외면에 스위치를 설치하고, 하우징의 수로 내벽면에 하방으로 돌출된 저항판을 형성한 구동판를 회전가능하게 설치함으로써, 구동판 저면 및 저항판에 수로를 통해 상방으로 이동하는 물이 마찰되도록 하여 물의 마찰면적을 증가시키면서, 구동판의 저항력을 증가시켜 구동판의 회전속도를 조절한다. 본 발명에 따르면, 구동판 양측 저면으로 저항판을 돌출 형성하여, 수로와 구동판 간의 간격이 감소될 우려가 없고, 구동판 저면 및 저항판에 물을 마찰시켜 마찰면적 증가와 동시에 마찰력이 향상되며, 특히, 이 마찰력 향상에 의해 구동판이 물의 저항에 의해 민감하게 작동되어, 구동판을 신속하게 회전시킬 수 있고, 또한, 구동판의 신속한 작동으로 물의 흐름 여부를 정확하게 검지할 수 있으며, 구동판의 저항력에 비례하도록 수로 내로 공급되는 물의 수압을 저감할 수 있고, 또한, 다양한 수압을 갖는 관로 내에 유로감지장치를 설치하여 관로 내로 흐르는 물의 흐름 여부를 검지할 수 있으며, 이에따라, 제품의 신뢰성이 향상되는 장점이 있다.
