[0036] It can be understood that the water tank bottom can also be provided with two spaced apart conductive rods, and the two conductive rods, the warning light, the buzzer and the driving motor 34 form a closed circuit. Since water has the property of being conductive, when water falls into the water tank bottom, the originally disconnected state of the two conductive rods can be switched to the pass-through state, thereby causing the warning light to emit light, the buzzer to emit a sharp sound, and the driving motor 34 to operate.

[0037] In order to enable the fault alarm device 100 to also emit a sound alarm when the buzzer is damaged and cannot emit a sound, in the embodiment of the present application, the top of the swing body 23 is provided with a warning plate 7, the length direction of the warning plate 7 is perpendicular to the length direction of the swing body 23, and a bell is hung at each end of the warning plate 7.

[0038] When the water tank in the detection main body 1 is not directly below the bottom of the cold water tank 200 or the hot water tank, or the water leakage directly flows down from the side wall of the cold water tank 200 or the hot water tank without passing through the bottom of the cold water tank 200 or the hot water tank, in order to ensure that the water leakage accurately falls into the water tank, in the embodiment of the present application, the water tank includes a guide section 14 and a water collecting section 15. The guide section 14 is in the shape of an inverted circular cone, which can cause the water leakage falling on the guide section 14 to flow in the direction of the water collecting section 15. The water collecting section 15 is in the shape of a column, and the top of the water collecting section 15 is fixedly connected to the bottom of the guide section 14 to collect water leakage. In this way, the bottom of the guide section 14 is provided with the column-shaped water collecting section 15, and compared with the inverted conical water tank, the inverted conical water tank can collect more water leakage under the condition of reaching the same water level. The radius of the bottom surface of the water collecting section 15 can be selected to be the same as the smaller cross-sectional radius of the inverted cone, so that the water leakage collected under the condition of reaching the same water level can cause the water leakage signal to be emitted by the water immersion sensor 4, and the leakage fault of the cold water tank 200 and the hot water tank can be discovered more timely. It can be understood that the slot of the water tank can be below the cold water tank 200 and the hot water tank, or the two detection main bodies 1 can be respectively below the cold water tank 200 and the hot water tank.

[0039] If the inspector does not perform the inspection work due to various reasons or holidays, or the inspector does not notice the fault alarm prompt due to his own reasons, the water in the water receiving tank will slowly reach the tank opening and then overflow the water receiving tank to the ground. In order to reduce the waste of water resources and prevent the ground from being wetted by the leakage, in the embodiment of the present application, the detection main body 1 comprises a containing cavity and an annular groove 11, the containing cavity is arranged away from the water receiving tank, the annular groove 11 is arranged on the top of the detection main body 1 and surrounds the water receiving tank, and the groove bottom of the annular groove 11 is provided with a flow guide hole in communication with the containing cavity. When the leakage in the water receiving tank reaches the tank opening of the water receiving tank, the leakage will flow to all directions and flow into the annular groove 11, and then enter the containing cavity through the flow guide hole, so as to temporarily store the leakage in the containing cavity and avoid the leakage from overflowing to the ground.

[0040] Further, in the embodiment of the present application, the detection main body 1 further comprises a first drain valve 13 and a second drain valve 12, the first drain valve 13 is arranged in the water receiving tank to drain the leakage into the containing cavity, and the second drain valve 12 is arranged on the outer side wall of the detection main body 1 to drain the leakage in the containing cavity to the outside of the detection main body 1. In this way, when the inspector discovers the leakage fault of the cold water tank 200 and the hot water tank through the fault alarm device 100 and handles it, the water bucket can be placed at the second drain valve 12, the first drain valve 13 and the second drain valve 12 are twisted to drain the leakage in the water receiving tank into the water bucket, and then the detection main body 1 can be placed below the cold water tank 200 and the hot water tank to use the fault alarm device 100 repeatedly.
