Therefore, water flow can pass through the notch groove 421 to enter the groove 11, and the top plate 41 can be lifted by arranging the coaming 42, so that the water level detection piece 30 is convenient to mount.

In some alternative embodiments, as shown in fig. 3 and 6, the notched groove 421 includes a plurality of notches spaced around the lower periphery of the enclosing plate 42, and the shape of the notched groove 421 is a circular arc, so that the enclosing plate 42 is surrounded by a plurality of arches, which can ensure that it has sufficient structural strength to support the top plate 41, reduce material consumption, and save cost.

In some embodiments, as shown in fig. 3 and 6, the floating plate 40 is provided with a through hole 412, the water level detecting member 30 extends downward through the through hole 412 to the lower side of the floating plate 40, and the lower end of the water level detecting member 30 is not higher than the top of the notch 421. It can be understood that water flow continuously enters the groove 11 through the notch groove 421, when the inside of the floating plate 40 is not closed by the liquid level, that is, the liquid level does not reach the vertex of the notch groove 421, the floating plate 40 hardly floats, the lower end of the water level detecting member 30 is set to be not higher than the vertex of the notch groove 421, that is, the lower end of the water level detecting member 30 is lower than the vertex of the notch groove 421 or flush with the vertex of the notch groove 421, and thus, water leakage can be detected quickly.

In one embodiment, the water level detecting member 30 is fixedly coupled to the floating plate 40. That is, the water level detecting member 30 is fixedly coupled to the floating plate 40, the water level detecting member 30 does not move relative to the floating plate 40, and the water level detecting member 30 moves together with the floating plate 40.
