Referring to fig. 4, 5, 9 and 10, in some embodiments, the sewage tank assembly 100 further includes a second inner housing 180, the second inner housing 180 is connected to the first air duct section 161, the second inner housing 180 has an air duct port 181 and an air inlet channel 182, the second air duct section 162 is inserted into the air duct port 181 and extends toward the bottom of the sewage chamber 110, and the sewage chamber 110, the air inlet channel 182 and the separation chamber 120 are sequentially communicated.

In this way, the fluid may be sucked into the sewage chamber 110 through the sewage duct 160, and then the sucked fluid in the sewage chamber 110 may enter the separation chamber 120 through the air inlet 182, and after being intercepted and filtered by the filter housing 230 in the separation chamber 120 and separated by the water-air separator 220, the air is finally discharged through the air outlet 130. The specific flow direction may be indicated by reference to the dashed arrow in 3.

Referring to fig. 3 and 9, it should be noted that the cleaning apparatus may further include a detection assembly 400, the detection assembly 400 is used for detecting the sewage level in the sewage chamber 110, the detection assembly 400 is connected to the second housing, and a detection end of the detection assembly 400 extends into the sewage chamber 110.

Referring to fig. 4,5, 9 and 10, in one possible implementation, the sewage tank assembly 100 further includes a liquid guide 190, the second inner housing 180 has a liquid return port 183, the liquid guide 190 is connected to the liquid return port 183, and the liquid separated by the water-gas separation member 220 flows to the bottom of the sewage chamber 110 along the liquid return port 183 and the liquid guide 190 in sequence.

Thus, the liquid separated by the water-air separation unit 220 falls back to the second inner housing 180 by gravity, enters the liquid guide 190 through the liquid return port 183, and finally flows back to the sewage chamber 110 through the liquid guide 190 to be collected in the sewage chamber 110.

Illustratively, the liquid guide 190 may be a duckbill valve having a large diameter end and a small diameter end disposed opposite to each other, the large diameter end of the duckbill valve being connected to the liquid return port 183, so that the liquid separated by the water-air separator 220 may flow back to the sewage chamber 110 through the small diameter end of the duckbill valve, and the sewage of the sewage chamber 110 may not enter the duckbill valve, so that the sewage may be prevented from flowing back.

In addition, the sewage tank assembly 100 may further include one or more sealing rings, which may be disposed between the sewage duct member 160 and the tank body 140, or between the second inner case 180 and the tank body 140, and between the tank cover 150 and the tank body 140, to ensure sealability.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and not for limiting the same; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the application.
