[0071] As Figures 1 to 7As shown, the embodiment of the present application provides a cleaning device, which comprises a device main body 100, a floor brush 200 and a water supply assembly 300. The device main body 100 is connected with the floor brush 200, and the water supply assembly 300 is arranged on the device main body 100 or the floor brush 200. The floor brush 200 is used for cleaning a surface to be cleaned. The device main body 100 can be operated or held by a user to drive the floor brush 200 to move to realize the cleaning operation. The water supply assembly 300 is used for supplying cleaning water to the floor brush 200 to realize the functions of wet mopping and hot cleaning.

[0072] The floor brush 200 comprises a floor brush main body 210, a cleaning assembly 240, a hot cleaning assembly 230 and a plurality of cleaning pieces 220. The plurality of cleaning pieces 220 are connected to the floor brush main body 210. When the floor brush 200 performs the cleaning operation, the cleaning pieces 220 are in contact with the surface to be cleaned and wipe the surface to be cleaned. The cleaning assembly 240 and the hot cleaning assembly 230 are arranged on the floor brush main body 210, and the cleaning assembly 240 and the hot cleaning assembly 230 are located between adjacent cleaning pieces 220. The water supply assembly 300 is configured to supply water to the cleaning assembly 240 and the hot cleaning assembly 230 respectively.

[0073] It can be understood that the cleaning assembly 240 can be used to spray water to the cleaning pieces 220 to humidify the cleaning pieces 220. In some scenarios, the cleaning pieces 220 can realize the function of wet mopping, and in other scenarios, the cleaning pieces 220 can be washed to keep the cleaning pieces 220 clean. The floor brush main body 210 can be provided with a spraying channel 211. The hot cleaning assembly 230 comprises a heating module 231. The heating module 231 is configured to heat or evaporate the water supplied by the water supply assembly 300 and spray the hot water or high-temperature steam formed from the spraying channel 211. The hot water or high-temperature steam impacting on the surface to be cleaned can have a good removal effect on stains on the surface to be cleaned.

[0074] In some embodiments, the heating module 231 can be arranged at the side of the spraying channel 211 and communicate with the spraying channel 211. In this way, the heating module 231 is arranged close to the spraying channel 211, which can shorten the communication path between the heating module 231 and the spraying channel 211. The hot water or high-temperature steam generated by the heating module 231 can quickly enter the spraying channel 211 to wash the surface to be cleaned, thereby avoiding heat loss of the hot water or high-temperature steam and maintaining the hot water or high-temperature steam at a relatively high temperature to have a better cleaning effect.

[0075] It should be noted that the cleaning device provided by the embodiments of the present application can realize hot water or steam cleaning of the surface to be cleaned to remove stubborn stains by respectively arranging the cleaning assembly 240 and the hot cleaning assembly 230 on the floor brush 200, and shunting the clean water provided by the water supply assembly 300. The heating module 231 can be a boiler, and the heating module 231 can control the heating temperature by adjusting the power of the heating module 231, so as to control the state of the cleaning water. When the heating module 231 works at low power, hot water can be generated and delivered to the spray channel 211, and when the heating module 231 works at high power, high-temperature steam can be generated and delivered to the spray channel 211. The heating module 231 can also form a mixed fluid of hot water and steam, and only the cleaning function needs to be realized, which is not limited in the embodiments of the present application. In addition, in the embodiments of the present application, the cleaning fluid discharged after the water is heated by the heating module 231 can include but is not limited to hot water, high-temperature steam or a mixture of hot water and steam.

[0076] The specific arrangement positions of the hot cleaning assembly 230 and the cleaning assembly 240 and the specific cleaning process of the cleaning device will be described in detail below.

[0077] The moving direction of the floor brush 200 is defined as the X direction, and the first direction is the X direction, and the Y direction is perpendicular to the moving direction of the floor brush 200, that is, the width direction of the floor brush 200 is the Y direction.

[0078] Please continue to refer to Figures 1 to 7 In a possible implementation, the plurality of cleaning elements 220 can include a first cleaning element 220a and a second cleaning element 220b, and the first cleaning element 220a and the second cleaning element 220b are arranged at two ends of the floor brush main body 210 along the first direction. The cleaning assembly 240 and the hot cleaning assembly 230 are located between the first cleaning element 220a and the second cleaning element 220b.

[0079] It can be understood that the first direction is the moving direction of the floor brush 200 during cleaning, and the first cleaning element 220a and the second cleaning element 220b can be located at the front and rear ends of the floor brush 200 along the cleaning direction, so that one of the first cleaning element 220a and the second cleaning element 220b can be used for wet mopping, and the other can be used for drying the floor. And since the components of the hot cleaning assembly 230 and the cleaning assembly 240 are arranged between the two cleaning elements 220, the space utilization is improved.

[0080] In some embodiments, the spraying channel 211 can be located between the first cleaning member 220a and the second cleaning member 220b, and the spraying channel 211 has a distance from the first cleaning member 220a and the second cleaning member 220b, so that the hot water or high-temperature steam sprayed by the spraying channel 211 can flush the surface to be cleaned corresponding to the area between the first cleaning member 220a and the second cleaning member 220b.

[0081] During the cleaning process of the brush 200, one of the first cleaning member 220a and the second cleaning member 220b can first wet mop the area to be cleaned, then the spraying channel 211 passes through the area, flushes it by hot water or high-temperature steam, removes stubborn stains, and finally the other of the first cleaning member 220a and the second cleaning member 220b passes through the area to dry it.

[0082] For example, the heating module 231 can be arranged between the spraying channel 211 and the first cleaning member 220a, or the heating module 231 can be arranged between the spraying channel 211 and the second cleaning member 220b, so that the distance between the heating module 231 and the spraying channel 211 is short, and the path of the hot water or steam flow is short, thereby avoiding heat loss.

[0083] The spraying channel 211 can be located at a middle position between the first cleaning member 220a and the second cleaning member 220b, for example, the spraying channel 211 can be arranged parallel to the first cleaning member 220a and the second cleaning member 220b, and the distance between the spraying channel 211 and the first cleaning member 220a and the distance between the spraying channel 211 and the second cleaning member 220b can be equal or approximately equal, so that two relatively independent mounting areas are formed on both sides of the spraying channel 211, thereby facilitating the arrangement of the heating module 231 and other components.

[0084] In some embodiments, the spraying channel 211 can extend in a second direction, and the spraying channel 211 has a plurality of nozzles 2111, and the plurality of nozzles 2111 can be arranged at intervals along the extension direction of the spraying channel 211, wherein the second direction has an angle with the first direction.

[0085] It can be understood that the second direction can be the Y direction, and the plurality of nozzles 2111 of the spraying channel 211 are arranged in the width direction of the brush 200, so that the hot water or steam sprayed by the spraying channel 211 through the nozzles 2111 can cover different areas in the width direction of the cleaning path of the cleaning device, thereby increasing the cleaning area.

[0086] The water flow path of the hot cleaning assembly 230 will be described below.

[0087] Please continue to refer to Figures 1 to 7In a possible implementation, the thermal cleaning assembly 230 can further include a first pipeline 232 and a first driving unit 233, the first driving unit 233 can be connected to the first pipeline 232, a water inlet end of the first pipeline 232 is in communication with the water supply assembly 300, and a water outlet end of the first pipeline 232 is in communication with the heating module 231.

[0088] It can be understood that the first driving unit 233 can be a water pump, the first driving unit 233 can provide driving force for water flow from the water supply assembly 300 to enter the first pipeline 232, and the water flow from the water inlet end of the first pipeline 232 to the water outlet end, and the water flow from the water outlet end of the first pipeline 232 can form hot water or high-temperature steam after entering the heating module 231.

[0089] For example, the heating module 231 and the first driving unit 233 can be distributed on opposite sides of the spray channel 211, so as to shorten the water flow path between the first driving unit 233 and the heating module 231, so that the water flow entering the heating module 231 has a higher flow rate and water pressure, and the heating or evaporation speed of the water flow in the heating module 231 is improved. In addition, the water pressure formed by the first driving unit 233 can make the hot water or high-temperature steam sprayed by the spray channel 211 have a certain impact force, thereby having a better cleaning effect on stubborn stains.

[0090] In some embodiments, the side of the spray channel 211 facing the heating module 231 can be provided with a connecting protrusion 2112, the connecting protrusion 2112 has a pipe joint 2113, and the thermal cleaning assembly 230 can further include a steam guide pipe 234, the steam guide pipe 234 is connected between the outlet of the heating module 231 and the pipe joint 2113.

[0091] It can be understood that the hot water or high-temperature steam flowing out of the heating module 231 can enter the steam guide pipe 234, and then enter the spray channel 211 through the pipe joint 2113 after passing through the steam guide pipe 234, and the arrangement of the connecting protrusion 2112 can further shorten the path between the heating module 231 and the spray channel 211, that is, shorten the length of the steam guide pipe 234, so that the hot water and steam flowing out of the heating module 231 can be quickly injected into the spray channel 211.

[0092] The water flow path in the cleaning assembly 240 will be described below.

[0093] Please continue to refer to Figures 1 to 7In a possible implementation, the cleaning assembly 240 can include a second pipeline 242, an adapter 241, a third pipeline 243, and a fourth pipeline 244. The water inlet end of the second pipeline 242 can be in communication with the water supply assembly 300, and the water outlet end of the second pipeline 242 can be in communication with the adapter 241. The water inlet ends of the third pipeline 243 and the fourth pipeline 244 are both in communication with the adapter 241, and the water outlet end of the third pipeline 243 can be directed toward the first cleaning member 220a, and the water outlet end of the fourth pipeline 244 can be directed toward the second cleaning member 220b.

[0094] It can be understood that the cleaning water supplied by the water supply assembly 300 can first enter the second pipeline 242, and after being branched by the adapter 241, the water flows into the third pipeline 243 and the fourth pipeline 244, respectively, and the third pipeline 243 and the fourth pipeline 244 can supply water to the first cleaning member 220a and the second cleaning member 220b, respectively, so as to meet the humidification requirements in different scenarios, and the first cleaning member 220a and the second cleaning member 220b can be cleaned at the same time.

[0095] For example, the adapter 241 can be a tee joint, that is, the adapter 241 has three adapter ports in communication with each other, so as to connect the second pipeline 242, the third pipeline 243, and the fourth pipeline 244.

[0096] In some embodiments, the first cleaning member 220a can be located at the front end of the brush body 210 along the first direction, the second cleaning member 220b can be located at the rear end of the brush body 210 along the first direction, and the cleaning assembly 240 can further include a first control valve 245 connected to the fourth pipeline 244.

[0097] It can be understood that when the brush 200 is in cleaning operation, the first cleaning member 220a can be used for wet mopping, and water is directly supplied to the first cleaning member 220a through the third pipeline 243, and the second cleaning member 220b can be selectively supplied with water for drying the ground. When the second cleaning member 220b needs to be cleaned, the fourth pipeline 244 is opened by the first control valve 245, so that the cleaning water is sprayed to the second cleaning member 220b.

[0098] It should be noted that the water inlet end of the hot cleaning assembly 230 can be connected with a first one-way valve 235, and the water inlet end of the cleaning assembly 240 can be connected with a second one-way valve 246. The first one-way valve 235 and the second one-way valve 246 are both in communication with the water supply assembly 300. The first one-way valve 235 allows the cleaning water to flow from the water supply assembly 300 to the hot cleaning assembly 230 in one direction, and the second one-way valve 246 allows the cleaning water to flow from the water supply assembly 300 to the cleaning assembly 240 in one direction, so as to avoid backflow of the cleaning water and ensure smooth water flow supply.

[0099] Exemplarily, the first one-way valve 235 and the second one-way valve 246 are arranged side by side on the same side of the injection channel 211. When the pipeline of the water supply assembly 300 is connected, the water supply assembly 300 can be connected to the water circuits of the hot cleaning assembly 230 and the cleaning assembly 240 in a centralized manner, improving the convenience of pipeline connection.

[0100] In the cleaning device provided by the embodiments of the present application, the sewage generated during the cleaning process by the cleaning member 220 can be recycled, which will be described in detail below.

[0101] Please continue to refer to Figures 1 to 7 , in a possible implementation manner, the cleaning device may further include a sewage tank 400. The sewage tank 400 may be arranged on the floor brush 200. The floor brush 200 may further include a sewage recovery pipe 250. Both ends of the sewage recovery pipe 250 may be provided with sewage ports 251. The two sewage ports 251 respectively face the first cleaning member 220a and the second cleaning member 220b. Any one of the two sewage ports 251 is communicated with the sewage tank 400.

[0102] It can be understood that the sewage tank 400 can recycle the sewage generated during the cleaning process. By arranging the sewage recovery pipe 250, the sewage generated by the two cleaning members 220 can be centrally recovered, avoiding stain residue and ensuring a good cleaning effect.

[0103] In some embodiments, the sewage recovery pipe 250 may be arranged across the upper part of the injection channel 211. The sewage recovery pipe 250 and the injection channel 211 divide the floor brush main body 210 into multiple installation areas. The hot cleaning assembly 230 and the cleaning assembly 240 are respectively arranged in different said installation areas, thereby improving the rationality of the space layout on the floor brush main body 210 and facilitating the connection of the water flow pipelines.

[0104] Exemplarily, the sewage recovery pipe 250 may be arranged along the X direction. Thus, the sewage recovery pipe 250 and the injection channel 211 may be perpendicular or approximately perpendicular. The sewage recovery pipe 250 and the injection channel 211 divide the inside of the floor brush main body 210 into a "field" - shaped area, that is, four installation areas are formed. The heating module 231 may be arranged in any one of the installation areas, and the first driving unit 233 may be arranged in the installation area adjacent to the heating module 231. The remaining two adjacent installation areas may respectively arrange two first one-way valves 235, the second one-way valve 246, and the first control valve 245.

[0105] In some embodiments, the cleaning device can further include a battery module 110 and a charging module 260, the battery module 110 and the charging module 260 are electrically connected, the battery module 110 is arranged on any one of the floor brush 200 and the device main body 100, the charging module 260 is arranged in any one of the plurality of mounting areas, the cleaning device can be charged through the charging module 260, so that the cleaning device can perform wireless cleaning operation.

[0106] It can be understood that the cleaning device can be equipped with a base station, the cleaning device can be placed on the base station, the base station can be provided with a charging port, the connector of the charging module 260 can be located at the bottom of the floor brush 200, when the floor brush 200 is supported on the base station, the charging module 260 can be docked with the charging port on the base station, thereby realizing charging of the battery module 110.

[0107] The cleaning device provided by the embodiment of the application can be provided with the water supply assembly 300 on the device main body 100 or on the floor brush 200, in order to ensure the compactness of the structure of the floor brush 200, the structure and arrangement mode of the water supply assembly 300 will be described below by taking the water supply assembly 300 arranged on the device main body 100 as an example.

[0108] Please continue to refer to Figures 1 to 7 In a possible implementation, the water supply assembly 300 can include a clean water tank 310, a first water supply pipe 320, a second water supply pipe 330 and a clean water detection module 340, the inlets of the first water supply pipe 320 and the second water supply pipe 330 are in communication with the clean water tank 310, the outlet of the first water supply pipe 320 is in communication with the hot cleaning assembly 230, and the outlet of the second water supply pipe 330 is in communication with the cleaning assembly 240.

[0109] It can be understood that the clean water detection module 340 can be used to detect the water flow flowing through the first water supply pipe 320 and the second water supply pipe 330, so as to ensure the cleanliness of the supplied water flow while realizing the independence of water supply between the cleaning assembly 240 and the hot cleaning assembly 230.

[0110] In some embodiments, the water supply assembly 300 can further include a second driving unit 350 and a filter module 360, the filter module 360 is connected to the first water supply pipe 320, and the filter module 360 is configured to filter the water flowing through the second water supply pipe 330, the second driving unit 350 is connected to the first water supply pipe 320, and the second driving unit 350 is configured to pump water to the cleaning assembly 240. For example, the second driving unit 350 can be a water pump.

[0111] In this way, on the one hand, the water sprayed by the cleaning assembly 240 to the cleaning element 220 has a certain water pressure, and on the other hand, the water flowing into the heating module 231 is free of scale and impurities, thereby avoiding damage to the heating module 231.

[0112] It should be noted that the device body 100 and the floor brush 200 can be movably connected through a hinge or a hose, etc. The device body 100 can rotate relative to the floor brush 200 to realize different cleaning postures. A vertical micro switch and a vertical limit buckle can be arranged on the floor brush 200. The vertical micro switch can be electrically connected with the controller of the cleaning device. When the cleaning device is not in use, the device body 100 can be in a vertical state relative to the floor brush 200. At this time, the device body 100 can trigger the vertical micro switch, so as to control the cleaning device to stop working through the controller to save energy and avoid continuous spraying of cleaning water. The vertical limit buckle can maintain the cleaning device in a vertical state, which is more labor-saving.

[0113] Figure 8 A structure diagram of the sewage tank in the cleaning device provided by the embodiment of the present application is provided, Figure 9 A sectional view of the sewage tank in the cleaning device provided by the embodiment of the present application is provided Figure 1 Figure 10 A bottom structure diagram of the sewage tank in the cleaning device provided by the embodiment of the present application is provided, Figure 11 A top view of the floor brush body in the cleaning device provided by the embodiment of the present application is provided, Figure 12 A sectional view of the sewage tank in the cleaning device provided by the embodiment of the present application is provided Figure 2 Figure 13 An internal structure diagram of the sewage tank in the cleaning device provided by the embodiment of the present application is provided Figure 1 Figure 14 An internal structure diagram of the sewage tank in the cleaning device provided by the embodiment of the present application is provided Figure 2

[0114] Please refer to Figures 3 to 14 The cleaning device provided by the embodiment of the present application can further include a controller. The sewage tank 400 is detachably arranged on the floor brush 200. The sewage tank 400 can include a tank body 410 and a water level detection assembly 420. The tank body 410 has a sewage cavity 401. The water level detection assembly 420 includes a detection piece 421. The detection piece 421 is electrically connected with the controller. The detection piece 421 is arranged on the side wall of the tank body 410 and at least partially extends into the sewage cavity 401 to detect the water level of the sewage in the sewage cavity 401.

[0115] ​​​​It can be understood that the part of the detection piece 421 located in the sewage cavity 401 can be regarded as a conductive contact point. When the water level in the sewage cavity 401 does not reach the height of the detection piece 421, the conductive contact point of the detection piece 421 only contacts air, and the resistance is approximately infinite. When the water level of the sewage in the sewage cavity 401 rises to the height of the detection piece 421, the conductive contact point of the detection piece 421 contacts the sewage. Since the sewage has a conductive property, the electrical signal fed back by the detection piece 421 to the controller changes, thereby determining that the water level in the sewage cavity 401 reaches the full water level, that is, it can be determined that the sewage tank 400 is full.

[0116] It should be noted that the cleaning equipment provided by the embodiment of the present application detects the water level in the sewage tank 400 by setting the water level detection assembly 420 to determine whether the sewage in the sewage tank 400 is full, so that the working of the cleaning equipment can be stopped when the sewage reaches the full water level, prompting to clean the sewage, so as to avoid sewage overflow.

[0117] The specific installation structure of the water level detection assembly 420 and the export mode of the electrical signal of the detection piece 421 will be described in detail below.

[0118] Please continue to refer to Figures 3 to 14 In a possible implementation, the water level detection assembly 420 can further include a conductive elastic needle 422. The conductive elastic needle 422 can be arranged outside the tank body 410. The detection piece 421 can be electrically connected with the conductive elastic needle 422. The adapter contact point 212 can be arranged on the brush body 210 and electrically connected with the controller. When the sewage tank 400 is arranged on the brush 200, the conductive elastic needle 422 abuts against the adapter contact point 212.

[0119] It can be understood that through the conductive elastic adapter, when the sewage tank 400 is installed on the brush 200, the detection piece 421 can be electrically connected with the adapter contact point 212, and then the detection piece 421 can be electrically connected with the controller to form a detection control loop. The arrangement of the conductive elastic needle 422 can ensure the reliability of the electrical connection between the sewage tank 400 and the adapter contact point 212 when the sewage tank 400 is placed on the brush 200, avoiding poor contact.

[0120] It should be noted that the detection piece 421 and the conductive elastic needle 422 can be metal pieces, and the adapter contact point 212 is a metal contact point. The material can include but is not limited to copper, aluminum, iron, silver and other metals or alloys. The specific metal material of the present application is not limited.

[0121] In some embodiments, the water level detection assembly 420 can further include a fixed cover plate 423, which can be connected to the outer wall of the sewage tank 400, and the conductive spring needle 422 is located between the fixed cover plate 423 and the outer wall of the sewage tank 400, and the conductive spring needle 422 at least partially extends from the bottom wall of the sewage tank 400.

[0122] It can be understood that a mounting area can be formed between the fixed cover plate 423 and the side wall of the tank body 410, and the conductive spring needle 422 can be vertically arranged in the mounting area, and the conductive spring needle 422 can be limited by the fixed cover plate 423 to ensure the reliability of the installation of the conductive spring needle 422. In addition, one of the conductive spring needle 422 and the adapter contact 212 can be elastically floating, so that when the two abut, the elastic pre-tightening force of the abutment can be provided, and the conductive spring needle 422 and the adapter contact 212 can always maintain a good electrical connection state.

[0123] For example, the fixed cover plate 423 can be fixed to the side wall of the sewage tank 400 by disassembly, for example, the fixed cover plate 423 can be connected to the side wall of the sewage tank 400 by bolts or screws and the like fasteners, and the side wall of the sewage tank 400 can be provided with a groove, and the water level detection assembly 420 can be arranged in the groove, and the shape of the fixed cover plate 423 matches the shape of the groove, thereby ensuring the flatness of the appearance of the sewage tank 400.

[0124] In some embodiments, the side of the fixed cover plate 423 facing the sewage tank 400 can abut against the detection piece 421, and the side wall of the sewage tank 400 has a through hole, and the detection piece 421 can be arranged in the through hole, and the water level detection assembly 420 can further include a first sealing piece 424, which can be sleeved on the detection piece 421, and the first sealing piece 424 abuts between the detection piece 421 and the outer wall of the sewage tank 400.

[0125] It can be understood that the fixed cover plate 423 can press the detection piece 421 to ensure the stability and reliability of the installation of the detection piece 421 in the through hole of the side wall of the sewage tank 400, and through the arrangement of the first sealing piece 424, the sewage cavity 401 can have good sealing performance while the detection piece 421 extends into the sewage cavity 401, and the leakage of sewage can be avoided.

[0126] For example, the first sealing piece 424 can be a sealing ring, for example, a sealing ring made of elastic sealing materials such as silica gel and rubber.

[0127] It should be noted that the detection piece 421 and the conductive spring needle 422 can be connected by a wire, and the wire can be collected between the fixed cover plate 423 and the side wall of the sewage tank 400, and the wire can also be shielded and fixed by the fixed cover plate 423.

[0128] In addition, the water level detection assembly 420 can be multiple, and the detection pieces 421 of the multiple water level detection assemblies 420 are distributed at different positions of the sewage tank 400 along the length direction of the sewage tank 400, which can improve the accuracy of judging the water level in the sewage tank 400. For example, the water level detection assembly 420 is two, and the two water level detection assemblies 420 can be arranged at both ends of the same side wall of the sewage tank 400. When the sewage tank 400 is tilted, at least one water level detection assembly 420 can still detect whether the sewage is at the full water level, thereby avoiding sewage leakage. The brush main body 210 can be provided with multiple switching contact points 212 at the corresponding positions, and when the sewage tank 400 is installed on the brush 200, the positions of the multiple switching contact points 212 can correspond to the multiple electrically-conductive elastic needles 422 of the water level detection assembly 420 one by one.

[0129] The structure of the sewage recovery of the sewage tank 400 and the sewage recovery mode will be described in detail below.

[0130] Please refer to Figures 7 to 14 In a possible implementation, the cleaning device can further include an air suction fan 500, and the brush 200 can further include an air suction duct 270, the air suction fan 500 and the air suction duct 270 are in communication, and the air inlet 271 of the air suction duct 270 and the sewage cavity 401 are in communication, so that a negative pressure can be formed in the sewage cavity 401.

[0131] It can be understood that when the air suction fan 500 works, the air flow formed by the air suction fan 500 flows from the sewage cavity 401 into the air suction duct 270, and then is discharged from the air suction duct 270 through the air suction fan 500. When the sewage cavity 401 is in a negative pressure state, the sewage generated by the cleaning element 220 can be sucked into the sewage tank 400, thereby improving the sewage recovery efficiency. The size of the negative pressure for sewage recovery in the sewage cavity 401 depends on the power of the air suction fan 500, and the power of the air suction fan 500 can be adjusted, so that different power with different suction force can be used according to different application scenarios.

[0132] In some embodiments, the tank body 410 has a sewage inlet pipe 411 and an air suction pipe 412, the sewage inlet 4111 of the sewage inlet pipe 411 and the sewage recovery pipe 250 are in communication, and the sewage cavity 401 can be provided with a sewage suction port 402, the sewage suction port 402 and the sewage inlet pipe 411 are in communication, the air suction pipe 412 has an air outlet 4121 and an air suction port 4122, the air outlet 4121 can be docked and communicated with the air inlet 271 of the air suction duct 270, and the air suction port 4122 can be communicated with the sewage cavity 401.

[0133] It can be understood that the air flow in the sewage tank 400 can enter the air suction pipe 412 from the air suction port 4122, and flow into the air suction duct 270 from the air outlet 4121, so as to form a negative pressure in the sewage cavity 401. The negative pressure air flow formed in the sewage cavity 401 can suck the sewage into the sewage cavity 401 through the sewage suction port 402, that is, the sewage generated by the cleaning member 220 first enters the sewage recovery pipe 250, then enters the sewage inlet pipe 411 through the inlet, and finally enters the sewage cavity 401 from the sewage suction port 402. In this way, on the one hand, the backflow of the sewage in the sewage suction cavity 401 under the action of gravity can be avoided, and on the other hand, the sewage in the sewage cavity 401 can be prevented from entering the air suction duct 270, so as to ensure the dry working environment of the air suction fan 500.

[0134] For example, the sewage suction port 402 and the air suction port 4122 can be located at opposite sides in the sewage cavity 401, so as to increase the interval distance between the sewage suction port 402 and the air suction port 4122, and prevent the sewage from splashing into the air suction pipe 412. For example, the sewage suction port 402 and the air suction port 4122 can be located at two ends of the sewage tank 400 along the length direction of the sewage tank 400.

[0135] In some embodiments, the sewage inlet pipe 411 can be located at the bottom wall of the sewage cavity 401, and the sewage suction port 402 can be directed to the top wall of the sewage cavity 401, so as to facilitate the docking of the sewage inlet pipe 411 and the sewage recovery pipe 250 on the floor brush 200. The air suction pipe 412 can be located at the top wall of the sewage cavity 401, so as to increase the distance between the air suction pipe 412 and the water surface of the sewage in the sewage cavity 401, and thus the surface sewage can enter the air suction pipe 412.

[0136] In order to block the surge of the sewage in the sewage cavity 401, the sewage tank 400 can further include a first baffle 413, which can be arranged around the sewage suction port 402. In addition, the sewage tank 400 can further include a second baffle 414, which can be arranged around the air suction port 4122, so as to prevent the sewage from splashing into the air suction pipe 412. It should be noted that only one of the first baffle 413 and the second baffle 414 can be provided, or both of them can be provided, and the embodiments of the present application do not make specific limitation thereon.

[0137] For example, the first baffle 413 and the second baffle 414 can be integrally formed with the tank body 410, or the first baffle 413 and the second baffle 414 can be welded to the cavity wall of the sewage cavity 401, and the embodiments of the present application do not make specific limitation thereon.

[0138] In a possible implementation, the sewage tank 400 can further include a first filter 430 and a pressing plate 431. The first filter 430 can be arranged at the air suction port 4122, and the pressing plate 431 can be located at a side of the first filter 430 away from the cavity wall of the sewage cavity 401, and the pressing plate 431 and the first filter 430 abut.

[0139] It can be understood that when the air flow enters the air suction duct 412 from the sewage cavity 401, the air flow first flows through the first filter 430, so that the first filter 430 can filter the air flow entering the air suction duct 412, ensure the dryness and cleanliness of the air flow entering the air suction duct 270, and avoid damage to the air suction fan 500.

[0140] For example, the first filter 430 can be a sponge block or other air-permeable and water-absorbing materials, so that even if part of the water vapor or water droplets enters the air suction port 4122 with the air flow, it can be absorbed by the first filter 430.

[0141] In addition, the pressing plate 431 can also play a blocking role when fixing the first filter 430, so as to avoid the sewage splashed or shaken to wet the first filter 430, thereby reducing the filtering effect of the first filter 430. The pressing plate 431 can be detachably installed on the cavity wall of the sewage tank 400 by screws or other detachable ways, so as to facilitate replacement of the first filter 430, so as to ensure that the first filter 430 can maintain good filtering and water absorption effect.

[0143] Please refer to Figure 15 and Figure 16 , combined with Figure 12 In a possible implementation, the sewage tank 400 can further include a grid plate 415. The grid plate 415 can be arranged in the sewage cavity 401, and the grid plate 415 can divide the sewage cavity 401 into at least two accommodation areas. The sewage suction port 402 and the air suction port 4122 are located in different accommodation areas, so that dry and wet separation can be realized in the sewage cavity 401, thereby improving the convenience of cleaning the sewage cavity 401.

[0144] Exemplarily, the grid plate 415 can be connected with opposite two side walls of the sewage cavity 401, so as to divide the sewage cavity 401 into two accommodation areas arranged along the length direction of the sewage tank 400, and the grid plate 415 can be provided with water passing holes. The suction port 402 can be arranged in the accommodation area a, and the air suction port 4122 can be arranged in the accommodation area b. When sewage mixed with impurities enters the accommodation area a from the suction port 402, the impurities will be left in the accommodation area a due to the blocking of the grid plate 415, and the sewage can enter the accommodation area b from the water passing holes of the grid plate 415, so as to realize the separation of the impurities.

[0145] In some embodiments, the top wall of the sewage cavity 401 can be provided with an accommodation groove 403, the accommodation groove 403 is arranged in a recessed manner away from the bottom wall of the sewage cavity 401, and the air suction duct 412 can be arranged in the accommodation groove 403, so as to increase the distance between the air suction duct 412 and the sewage surface in the sewage cavity 401, and reduce the possibility of sewage entering the air suction port 4122.

[0146] It can be understood that the accommodation groove 403 arranged in the sewage cavity 401 can form a protruding structure on the top of the outer wall of the sewage tank 400, and the shape of the protruding structure can match the shape of the air suction duct 412.

[0147] In order to facilitate opening of the sewage tank 400 for cleaning, the tank body 410 can include a bottom shell 416 and a cover plate 417, the cover plate 417 and the bottom shell 416 can be combined to form the sewage cavity 401, the cover plate 417 is arranged to be openable and closable relative to the bottom shell 416, for example, the cover plate 417 and the bottom shell 416 can be connected through a rotating shaft 418, so that the cover plate 417 can be opened by turning, and the cover plate 417 and the bottom shell 416 can be provided with a buckling structure for docking, so that the cover plate 417 and the bottom shell 416 can be fixed when the cover plate 417 is closed, and the tightness of the docking of the cover plate 417 and the bottom shell 416 is ensured, so that the sewage cavity 401 has good sealing performance.

[0148] In some embodiments, the air suction duct 412 can include a duct body 4123, an air guide pipe 4124 and a second sealing member 4125, the air suction port 4122 is arranged on the duct body 4123, and the air outlet 4121 is arranged on the air guide pipe 4124, wherein the duct body 4123 can be arranged on the cover plate 417, the air guide pipe 4124 can be arranged on the bottom shell 416, and when the cover plate 417 is closed relative to the bottom shell 416, the duct body 4123 and the air guide pipe 4124 are in docking communication, and the second sealing member 4125 abuts between the duct body 4123 and the air guide pipe 4124, so as to realize the communication between the air suction port 4122 and the air outlet 4121, and ensure that the air suction duct 412 has good sealing performance.
