As shown in fig. 4, the drainage passage 2041 includes a flow guide tube 20411 disposed at the bottom of the dirt collection box 204, a first drainage pipe 20412 disposed longitudinally and communicated with the flow guide tube 20411, and a second drainage pipe 20413 communicated with the first drainage pipe 20412. The honeycomb duct 20411 is an arc-shaped tubular structure which is arranged along the bottom surface of the sewage collecting box 204, and a water outlet of the honeycomb duct 20411 is arranged along the lowest position of the bottom of the sewage collecting box 204, so that sewage at the bottom of the sewage 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 member 2043 is arranged at a communication position of the first sewage draining pipe 20412 and the second sewage draining pipe 20413, the flexible blocking member 2043 is closed at a working state or a static state of the dust collection system at the communication position, 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. In another embodiment, the drainage pipe is a single pipe, the flow guide pipe 20411 is communicated with the drainage pipe, and a switch for controlling drainage is arranged on one side of the drainage pipe communicated with the external environment, so as to prevent the sewage from being drained under the action of gravity when the water level is low. 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.

The working state of the dust collection system refers to the working of the negative pressure device 202, and the interior of the dust collection system is in a negative pressure environment. Because the one end and the external environment intercommunication of first blow off pipe 20412 are kept away from to second blow off pipe 20413, this flexible baffle 2043 set up the passageway of closed blow off pipe and external environment for dust collecting structure 200 is inside only to be communicated with external environment through wind-guiding passageway 203, forms half confined space. Thus, in the working state of the dust collecting system, 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. In this embodiment, the first and second drain pipes 20412 and 20413 are disposed in an inverted "U" shape, the tops of the two drain pipes are connected, and a through hole for communicating the two drain pipes is reserved at a position close to the top.

Due to the arrangement of the strainer on the surface of the drain valve 307, the solid dirt will not be discharged through the drain valve 307 and will remain in the waste bin 102. Preferably, the waste bin 102 is removably connected to the floor collection structure 100 and is secured to the floor collection structure 100 by the bin cover 109 and the cover latch 1091.
