The capacitive sensor 2 comprises a detection end, and the detection end is attached to the water containing structure 1. Specifically, the capacitance sensor 2 can determine whether water is near the detection end by detecting the change of the electric quantity at the detection end. When water passes through the water-detecting sensor, the water forms a conductor to take away the electric quantity of the capacitive sensor 2 on the surface of the detecting end, so that the detecting circuit 3 can detect corresponding electric property changes.

In some embodiments, the water containing structure 1 may be an outlet tube 1 as shown in fig. 1, the outlet tube 1 comprising a housing comprising a mounting groove 11 for receiving the capacitive sensor 2. Wherein the shape of the mounting groove 11 matches the shape of the capacitive sensor 2, so as to mount the capacitive sensor 2 in the mounting groove 11. The mounting groove 11 may be a blind groove, and may also penetrate through the shell of the water containing structure 1, and the specific implementation manner is not limited.

The capacitive sensor 2 may be provided with a detent element that engages with the latching recess 12, so that the capacitive sensor 2 is fixed by the detent element being latched into the latching recess 12.

Moreover, the bottom of the mounting groove 11 can be a ceramic bottom plate 13, and the ceramic bottom plate 13 can use a better dielectric constant of the material to improve the detection sensitivity of the capacitance sensor 2.

In other embodiments, the capacitive sensor 2 of the water flow detection assembly is fixedly connected with the water containing structure 1 by installing a fixing member at the outer side.

Referring to fig. 2, another structure of the water flow detecting assembly according to the embodiment of the present application is shown.

As shown in fig. 2, the fixing member is a cover plate 4, and the periphery of the cover plate 4 is fixed on the water containing structure 1, i.e. the outlet pipe 1 in the figure, so that the capacitive sensor 2 is fixed between the water containing structure 1, i.e. the outlet pipe 1 and the cover plate 4 in the figure. The cover plate 4 can be utilized to better fix the capacitive sensor 2 on the water containing structure 1, and the use reliability of the capacitive sensor is improved. Specifically, the cover plate 4 can be fixed by screws 41, which facilitates the assembly and disassembly.

In some embodiments, the capacitance sensors 2 have two or more, and by providing a plurality of capacitance sensors 2, false detection can be avoided, thereby improving detection reliability. Specifically, the capacitive sensors 2 may be disposed at positions close to each other, or may be disposed at two opposite sides of the water containing structure 1, for example, two horizontal opposite sides in the tank, so as to ensure the accuracy of water level detection.

Specifically, the terminal surface of this capacitive sensor 2's sense terminal is ARC structure, and ARC structure's shape matches with the shape of holding water structure 1's casing surface to make capacitive sensor 2 better laminate and hold water structure 1, improve its sensitivity.

Referring to fig. 3, a structure of a detection circuit 3 according to an embodiment of the present disclosure is shown.
