The honeycomb duct 20411 is an arc-shaped tubular structure which is arranged along the bottom surface of the dirt collecting box 204, and the water outlet of the honeycomb duct 20411 is arranged along the lowest position of the bottom of the dirt collecting box 204, so that the sewage at the bottom of the dirt collecting box 204 can be smoothly discharged. In this embodiment, in order to achieve better diversion and sewage discharge efficiency, the arc-shaped diversion pipe 20411 is arranged around the bottom surface of the sewage collection box 204 for a half-cycle, and then is communicated with the first sewage discharge pipe 20412, so that sewage enters the second sewage discharge pipe 20413 via the first sewage discharge pipe 20412 and is discharged out of the sewage collection box 204. Specifically, the first sewage draining pipe 20412 is communicated with the second sewage draining pipe 20413 at a high water level point, a flexible blocking part 2043 is arranged at a communication position of the first sewage draining pipe 20412 and the second sewage draining pipe 20413, the flexible blocking part 2043 closes the communication position in a working state or a static state of the cleaning equipment, and the communication position is opened in a sewage draining state, so that sewage enters the second sewage draining pipe 20413 from the first sewage draining pipe 20412 via the high water level point. The purpose of arranging the double drain pipes and communicating the double drain pipes at the high point of the water level is to enable the sewage collecting box 204 to have certain water storage capacity, and prevent sewage from being discharged out of the sewage collecting box 204 through the drain pipes under the action of gravity when the water level is low. Because the sewage disposal channel 2041 pipe diameter of the sewage collection box 204 is small, in order to prevent solid impurities carried by sewage from blocking the sewage disposal channel 2041, a sewage collection box filter screen 2042 is arranged above the flow guide pipe and used for filtering the solid impurities carried by sewage. Specifically, set up the partition surface between honeycomb duct 20411 and the opening that wind-guiding passageway 203 set up in dirty box 204, set up dirty box filter screen 2042 of collection on the partition surface for sewage sets up the opening that the dirty box 204 of collection gets into dirty box 204 of collection via wind-guiding passageway 203, filters through dirty box filter screen 2042 of collection and then discharges by honeycomb duct 20411, avoids solid impurity to block sewage disposal passage 2041.

For example, the switch for controlling the water discharge may be a solenoid valve or the like. It can be understood that the blow-off pipe can also be a blow-off structure with three pipelines and more pipelines communicated end to end, and the arrangement of the multi-pipeline blow-off structure can further improve the water storage capacity of the sewage collecting box 204 so as to prevent sewage from being discharged under the action of gravity when the water level is low.

Thus, in the working state of the cleaning device, the negative pressure device 202 generates enough suction force in the semi-closed space to suck the dirt into the dirt collecting box 204 through the air guide channel 203. The sewage discharge state refers to the operation of a water pump connected with the sewage discharge passage 2041, and under the action of the water pump, sewage in the sewage collection box 204 forms impact force on the flexible blocking member 2043 at the water level high point of the first sewage discharge pipe 20412, so that the flexible blocking member 2043 deforms and displaces, thereby opening the communication position between the first sewage discharge pipe 20412 and the second sewage discharge pipe 20413, and enabling the sewage to enter the second sewage discharge pipe 20413 from the first sewage discharge pipe 20412 via the water level high point.

Wherein the length of the pipeline outside the sewage tank 304 is not less than the set high water level of the sewage tank 304. In order to ensure good sealing performance, a sealing gasket is arranged between the through hole and the wall of the right-angle pipe. The user can rotate the pipe, which is placed outside the sewage tank 304, around the through-hole within a certain range by the right-angle pipe 309. For example, with the horizontal line as a 0 degree axis, the outer right-angle tube can rotate around the through hole within plus or minus 90 degrees. Therefore, sewage in the sewage tank 304 can be discharged only by rotating the outer right-angle pipe, and the sewage tank is convenient and efficient. When the outer right-angle pipe rotates to the position that the height of the pipe opening is lower than the sewage level, sewage is discharged from the sewage tank 304 through the right-angle pipe 309; when the outer right-angle pipe rotates to the height of the pipe orifice higher than the sewage level, the sewage is still stored in the sewage tank 304. Further, a pipeline of the right-angle pipe 309 arranged outside the sewage tank 304 is connected with a floor drain or a sewer opening, and sewage is directly discharged into a sewer.
