Referring to fig. 5, in a specific implementation, the water blocking cover 232 may include a main baffle 2321 and at least one side baffle 2322 connected to a side of the main baffle 2321, where the main baffle 2321 is located at a side of the water outlet end of the sewage channel 212 and extends along a height direction of the tank 210, the side baffle 2322 is disposed at a side of the main baffle 2321 along the height direction of the tank 210, and the side baffle 2322 extends at least to a side of the water outlet end of the sewage channel 212 facing away from the tank cover unit 220 in the height direction of the tank 210, so that the main baffle 2321 and the side baffle 2322 are jointly enclosed outside the water outlet end of the sewage channel 212.

That is, the bottom ends of the main and side baffles 2321 and 2322 in the height direction of the tank 210 should be lower than the water outlet end of the sewage passage 212 to enhance the water blocking effect of the water blocking cover 232.

The height direction of the case 210 may refer to the X direction in fig. 1.

In this way, the main baffle 2321 and the side baffles 2322 may be arranged around the outer side of the water outlet end of the sewage channel 212, and block the side of the water outlet end of the sewage channel 212 facing the air inlet 221, so as to prevent sewage at the water outlet end of the sewage channel 212 from entering the filtering unit 240 due to splashing around.

It should be noted that, the water blocking cover 232 may further include a top baffle 2323, where the top baffle 2323 is disposed at the water outlet end of the sewage channel 212, so as to prevent the sewage from impacting upwards and directly splashing into the filtering unit 240 when the impact force of the sewage is large.

In one possible implementation, the side baffles 2322 are two, and the two side baffles 2322 are disposed on opposite sides of the main baffle 2321, and a side of the side baffles 2322 facing away from the main baffle 2321 encloses the opening of the water shield 232.

That is, the two side baffles 2322 and one main baffle 2321 together form a box-shaped water blocking cover 232 having an opening at a side, a part of sewage may flow to the sewage chamber 211 through the opening at the side, the main baffle 2321 and the two side baffles 2322 may block the sewage flowing out from the water outlet end of the sewage passage 212 from three directions to entirely cover one side of the water outlet end of the sewage passage 212 toward the air inlet 221, the water blocking effect of the water blocking cover 232 is better, and a part of sewage may flow back to the sewage chamber 211 along the main baffle 2321 and the two side baffles 2322.

Referring to fig. 3 to 5, in one possible implementation, the water guard 230 further includes a filtering portion 233 and a connecting portion 234, the filtering portion 233 being located on a side of the main baffle 2321 facing away from the cover unit 220, the filtering portion 233 being configured to intercept solid waste in the sewage. The connection portion 234 is connected between the main baffle 2321 and the filter portion 233, and the connection portion 234 has ventilation openings 2341 penetrating opposite sides of the connection portion 234.

In this way, the filtering portion 233 is disposed on the side, facing away from the tank cover unit 220, of the main baffle 2321, so that the filtering portion 233 extends into the sewage, so that when the sewage in the sewage cavity 211 is cleaned after the cleaning operation is completed, the filtering portion 233 can intercept and filter the solid garbage in the sewage, so as to realize solid-liquid separation, and therefore, the cleaning effect of the sewage is improved.

Since the filtering portion 233 is disposed on the water blocking member 230, the lower portion of the water blocking member 230 is immersed in the sewage, and the water blocking member 230 is disposed between the sewage channel 212 and the air inlet 221, which may cause insufficient air flow sucked by the dust collection assembly 110 and further cause a phenomenon that the sewage boils and rolls, the air inlet 2341 is opened at the connection portion 234 between the main baffle 2321 and the filtering portion 233, so as to increase the flow channel of the air flow, thereby increasing the air suction amount of the dust collection assembly 110.

In some embodiments, the vent 2341 communicates with a front side of the dirty water chamber 211 in the cleaning apparatus travel direction and a rear side of the dirty water chamber 211 in the cleaning apparatus travel direction.

Since the main baffle 2321 and the connection part 234 divide the soil chamber 211 into a front side in the cleaning apparatus traveling direction and a rear side in the cleaning apparatus traveling direction, the air inlet and the soil passage 212 are respectively located at the front and rear sides in the cleaning apparatus traveling direction of the soil chamber 211, in order for the air flow to smoothly enter the dust collection assembly 110 through the air vent 2341, it is necessary for the air vent 2341 to communicate with the front side in the cleaning apparatus traveling direction of the soil chamber 211 and the rear side in the cleaning apparatus traveling direction of the soil chamber 211.

It will be appreciated that if the air vent 2341 is connected to the left side of the dirt cavity 211 in the direction of travel of the cleaning apparatus and the right side of the dirt cavity 211 in the direction of travel of the cleaning apparatus, the effect of increasing the amount of suction of the suction assembly 110 cannot be achieved.

Wherein the cleaning device travel direction may refer to the Y direction in fig. 1.

In a specific implementation, at least a portion of the wall surface of the connecting portion 234 is hollowed out to form the ventilation opening 2341. For example, most of the wall surface of the connection portion 234 may be hollowed out, leaving only a small portion of the wall surface structure for connecting the water blocking cover 232 and the filtering portion 233, so that a larger ventilation opening 2341 may be formed, thereby increasing the flow passage of the air flow.

Referring to fig. 2 and 6, in one possible implementation, the sump assembly 200 further includes a water level detection unit 250, the water level detection unit 250 being connected to the cover unit 220, the water level detection unit 250 being configured to detect a water level of the sewage chamber 211.

In this way, the water level detection unit 250 may be disposed in the sewage chamber 211 to detect the water level of the sewage in the sewage chamber 211, so as to prevent the water level of the sewage from being too high, thereby causing a tumbling boiling phenomenon of the sewage and the sewage to enter the filtering unit 240.

With continued reference to fig. 2 and 6, in a specific implementation, the water level detecting unit 250 may include a detecting probe 251 and a connecting member 252 connected to each other, and the connecting member 252 is connected to the cover unit 220, and an extension length of the detecting probe 251 along the height direction of the case 210 is matched with an upper edge of the air vent 2341 along the height direction of the case 210.

In this way, the water level detecting unit 250 may be configured to detect the water level of the sewage by providing the detecting probe 251, and may be configured to fix the detecting probe 251 to the tank cover unit 220 by providing the connection member 252.

In order to ensure the flow channel of the air flow, when the water level of the sewage rises to the upper edge of the ventilation opening 2341, it is indicated that the water level of the sewage is higher, the sewage almost covers all the ventilation openings 2341, which may cause insufficient suction amount of the dust suction assembly 110 to cause tumbling boiling of the sewage, so that the detecting probe 251 needs to detect whether the water level of the sewage rises to the upper edge of the ventilation opening 2341, and the extending length of the detecting probe 251 along the height direction of the box 210 needs to be matched with the upper edge of the ventilation opening 2341, so as to avoid that the sewage completely covers the ventilation opening 2341.

Referring to fig. 6, in one possible implementation, the projection of the detection probe 251 on the sidewall of the case 210 at least partially overlaps with the projection of the ventilation opening 2341 on the sidewall of the case 210.

That is, the lower end of the extension length of the detecting probe 251 along the height direction of the box 210 should be located below the ventilation opening 2341, so that the detecting probe 251 can detect whether the water level of the sewage is higher than the upper edge of the ventilation opening 2341 in time, so as to avoid the sewage from completely blocking the ventilation opening 2341.

Referring to fig. 5, in some embodiments, at least a wall surface of the filtering part 233 is recessed to form a filtering groove 2331, and a wall of the filtering groove 2331 is provided with a plurality of filtering holes 2332.

Thus, when the sewage in the tank 210 is cleaned later, the liquid can flow through the filter holes 2332 at two opposite sides of the filter tank 2331, so that the solid garbage can be intercepted in the filter tank 2331, and the subsequent cleaning of the solid garbage of the filter part 233 is facilitated.

Wherein, the notch of the filter tank 2331 may face the rear side of the sewage chamber 211 in the traveling direction of the cleaning apparatus so as to filter solid garbage in sewage when the sewage is dumped.

In one possible implementation, the air inlet 221 faces the front side of the sewage chamber 211 in the cleaning apparatus traveling direction, and the sewage passage 212 is located at the rear side of the sewage chamber 211 in the cleaning apparatus traveling direction.

Thus, after the sewage flowing out from the water outlet end of the sewage channel 212 is blocked and gathered by the water blocking cover 232, the probability of splashing into the air inlet 221 is greatly reduced, and the air inlet direction of the air inlet 221 faces to the front side of the sewage cavity 211 away from the sewage channel 212, so that the sewage is further prevented from splashing into the filtering unit 240 and being sucked into the filtering unit 240 by air flow.

Referring to fig. 2 and 3, in a specific implementation, the cover unit 220 may include a first cover 222 and a second cover 223, the second cover 223 is connected to the first cover 222, the first cover 222 is connected to the case 210, the water blocking member 230 is connected to the first cover 222, and the filter unit 240 is connected to the second cover 223. The air inlet 221 is located on the first case cover 222, and an air inlet direction of the air inlet 221 forms an included angle with a height direction of the case 210.

In this way, the tank cover unit 220 may be provided by providing the first tank cover 222 to partially close the sewage chamber 211 of the tank body 210, and fixing the water blocking member 230 to the first tank cover 222, and by providing the second tank cover 223 for mounting the filter unit 240 and connecting with the apparatus main body 100. By inclining the air inlet direction of the air inlet 221 and the height direction of the box 210, the sewage is prevented from splashing into the filter unit 240 due to inertia and changing the flowing direction of the air flow when the moving speed of the cleaning device is high, and the sewage is prevented from being sucked into the filter unit 240 by the air flow.

The included angle may be set, for example, between 60 deg. -90 deg..
