Abstract

The invention discloses a water leakage sensor, which comprises a main body and a resistance measuring instrument, and is characterized in that the main body comprises a water inlet pipe and a water outlet pipe which are used for being connected with a water supply pipe, the water inlet pipe is internally provided with a sealing element; the sealing element can open or close according to pressure variations between two sides of the sealing element; the main body is further configured with a detection probe used for detecting resistance between the two sides of the sealing element, and the detection probe is electrically connected with the resistance measuring instrument. The water leakage sensor provided by the invention can be assembled on the water supply pipe to act as a one-way valve in use, so that the cost is saved, water leakage of any water outlet end of the water supply pipe can be detected, and the detection range is expanded.

Description

technical field [0001] The invention relates to the technical field of water leakage detection technology devices, in particular to a water leakage sensor. Background technique [0002] At present, the detection range and detection points of water leakage sensors on the market are limited. Users must place the water leakage sensor at a precise location with a high risk of water leakage when using it, so that the detection range of the sensor can be covered. However, water leakage has random characteristics. Once the water leakage point is out of the detection range of the sensor, the water leakage will not be prompted. However, if the user arranges a large number of water leakage sensors at home or in public bathrooms, the cost will inevitably increase. Contents of the invention [0003] The object of the present invention is to overcome the defects in the prior art, and provide a water leakage sensor which can be installed on a water terminal and has improved detection r...
