Water heating leakage monitoring device

The utility model discloses a water heating leakage monitoring device which comprises a detection module and a signal sending module which are in electric signal connection. Wherein the detection module comprises a relay, a triode, a resistor and a detection cable, one end of a control end of the relay is connected in series with a collector of the triode, and the other end is connected with a power supply; the emitter of the triode is grounded; the resistor is connected in parallel between the base and the emitter of the triode; the detection cable is connected between the power supply and the base electrode of the triode; the signal sending module is in electric signal connection with a normally-open contact and/or a normally-closed contact of the relay, and sends a preset alarm signal to a fire-fighting host after receiving a normally-open and/or normally-closed switching value signal input by the relay. According to the water heating leakage monitoring device provided by the utility model, the water leaka
