The working process of the sweeper is as follows:

when the sweeper is lifted or the sweeper is inclined to enable the roller and the ground to be cleaned to be in a non-contact ground-leaving state, the roller 2 and the first connecting rod 31 move downwards under the action of the spring 4, and as the rack part on the first connecting rod 31 and the rack part on the second connecting rod 32 are meshed with the gear 33, the gear 33 is driven to rotate when the first connecting rod 31 moves downwards, the second connecting rod 32 is driven to move upwards, and then the separating plate 5 is driven to move upwards to close the air outlet 101, so that sewage and garbage in the cavity are prevented from contacting the fan 02 after flowing out through the air outlet 101, and the service life of the fan 02 is prevented from being influenced. When the sweeper is placed on a surface to be cleaned and the roller 2 of the sweeper contacts with the surface to be cleaned, the roller 2 and the first connecting rod 31 move upwards, and as the rack part on the first connecting rod 31 and the rack part on the second connecting rod 32 are meshed with the gear 33, the gear 33 is driven to rotate when the first connecting rod 31 moves upwards, the second connecting rod 32 is driven to move downwards, and then the separating plate 5 is driven to move downwards to open the air outlet 101, so that when the sweeper works normally, separated air flows out through the air outlet 101.

When the sweeper is placed on a surface to be cleaned and the bottom of the driving wheel assembly 8 is completely contacted with the surface to be cleaned, the second side of the driving wheel assembly 8 moves upwards, at the moment, the vertical rod 71 is driven to move upwards, the first end of the cross rod is driven to move upwards when the vertical rod 71 moves upwards, at the moment, the second end of the cross rod 72 moves downwards, the rotating piece 73 drives the rotating shaft 151 to rotate, the wind shield 15 opens the air inlet channel 14, and therefore when the sweeper works normally, dust and the like cleaned by the cleaning module enter the separating module through the air inlet channel 14 to be separated, and separated gas is discharged after passing through the air outlet 101, the filter screen and the fan 02. When the sweeper is lifted or dumped to enable the bottom of the driving wheel assembly 8 and the surface to be cleaned to be in a non-contact ground-leaving state, the second side of the driving wheel assembly 8 moves downwards, at the moment, the vertical rod 71 moves downwards under the action of the torsion spring 74 to drive the first end of the cross rod 72 to move downwards, at the moment, the second end of the cross rod 72 moves upwards, the rotating member 73 drives the rotating shaft 151 to rotate reversely to enable the wind shield 15 to close the air inlet channel 14, and sewage and garbage in the chamber 10 are prevented from flowing onto the ground through the air inlet channel 14 and the cleaning module 03.

In the above embodiment, the traveling direction of the sweeper is the front.

The term "fluid communication" as used herein refers to a spatial positional relationship between two components or parts (hereinafter collectively referred to as a first part and a second part, respectively), that is, a fluid (gas, liquid, or a mixture of both) can flow along a flow path from the first part to the second part or/and be transported to the second part, or the first part and the second part may be directly communicated with each other, or the first part and the second part may be indirectly communicated with each other through at least one third party, and the third party may be a fluid channel such as a pipe, a channel, a conduit, a flow guiding member, a hole, a groove, or the like, or a chamber allowing the fluid to flow through, or a combination thereof.
