In some embodiments, the position of the sewage inlet 302 in the vertical direction in the sewage chamber 301 may be high

The conductive part 321 is arranged at the position along the vertical direction in the sewage cavity 301, so that the alarm of full water can be sent out when the water level is lower than the sewage inlet 0 port 302, and the sewage is prevented from flowing back from the sewage inlet 302.

The vertical direction can be defined as the X direction, the sewage inlet pipe 311 and the water level detecting member 320 can both extend along the X direction, one end of the water level detecting member 320, where the conductive portion 321 is disposed, extends downward along the X direction, and the position of the conductive portion 321 in the X direction is lower than the sewage inlet 302, when sewage accumulates from the bottom of the sewage cavity 301 toward the top of the sewage cavity 301 along the X direction, the water level of the sewage will contact the conductive portion 321 when being lower than the position of the sewage inlet 302, so that the water level detecting member 320 can feed back and send out the prompt information that the sewage tank 300 is full through the controller.

The specific principle of the water level detecting member 320 for judging the full water level of the sewage tank 300 will be described in detail.

With continued reference to fig. 2 to 7, in one possible implementation, the water level detecting member 320 may include a first electrode plate 320a and a second electrode plate 320b, the first electrode plate 320a and the second electrode plate 320b may be respectively located at opposite sides of the dirt inlet pipe 311, a first end of the water blocking member 330 is located between the first electrode plate 320a and the dirt inlet pipe 311, and a second end of the water blocking member 330 is located between the second electrode plate 320b and the dirt inlet pipe 311.

It is understood that the first electrode plate 320a and the second electrode plate 320b are electrically connected to the controller, when the sewage level in the sewage chamber 301 does not reach the full water level, the conductive portions 321 of the first electrode plate 320a and the second electrode plate 320b are not in contact with the sewage, and at this time, air is between the conductive portions 321 of the first electrode plate 320a and the second electrode plate 320b, so that the resistance between the first electrode plate 320a and the second electrode plate 320b can be approximately infinite, i.e., the first electrode plate 320a and the second electrode plate 320b are in an open state; when the water level in the sewage chamber 301 rises, the conductive portions 321 of the first electrode tab 320a and the second electrode tab 320b are in contact with the sewage, and the first electrode tab 320a and the second electrode tab 320b are in a conductive state due to the conductivity of the sewage. In this way, it is possible to judge whether the water level reaches the height of the water level detecting member 320 through the change of the resistance state between the first electrode tab 320a and the second electrode tab 320b, thereby improving the accuracy of the detection result.
