The invention relates to the technical field of liquid detection, and discloses a liquid detection device. The device includes a circuit device. The circuit device includes a circuit device body. A circuit board is fixedly connected with one end of the circuit device body. An end of the circuit body near the circuit board is connected inside an outer shell in an inserting manner. A prism is arranged in the middle of the outer shell. A groove is formed at the one end of the circuit device body near the circuit board. An optical coupler realization area is arranged in the groove. An optical coupler circuit is arranged inside the optical coupler realization area, and includes a photoelectric light emitting tube and a photoelectric receiving tube. A dielectric constant detection area is arranged inside the circuit board. The circuit device is connected with the outer shell in an inserting manner. According to the liquid detection device, whether the outer shell is in air, oil or water canbe known through arrangement of the optical coupler realization area and the dielectric constant detection area and cooperation of an optical coupler and dielectric constant detection to achieve the detection purpose.
Description
technical field [0001] The invention relates to the technical field of liquid detection, in particular to a liquid detection device. Background technique [0002] At present, the known device capable of distinguishing liquids with different characteristics consists of a float and several reed switches. After the device is fixed to the corresponding position, the characteristics of the corresponding liquid are confirmed by using the difference in buoyancy of different liquids on the float. However, its structure is large, and it has high requirements on the purity of the liquid, and requires a large amount of liquid to be tested. In the case of moving parts, there is a hidden danger of jamming. In the case of a small amount of liquid to be detected, it is most inapplicable (such as leak detection of double-layer oil tanks in gas stations), which may easily lead to misjudgment. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficie...
