The suction and discharge assembly 700 is connected to the sewage tank 600, and can generate negative pressure in the sewage tank 600, so that sewage in the sewage collecting tank 510 can be sucked into the sewage tank 600 through the sewage outlet 513, the sewage inlet 611 and the water inlet channel 613 communicated with the sewage inlet 611, and overflow of sewage in the sewage collecting tank 510 is avoided.

In an embodiment of the present application, the wiper portion 511 is integrally formed (e.g., integrally injection molded) with the sewage collecting tank 510, and the wiper portion 511 is a protrusion located at the top of a sidewall of the sewage collecting tank 510 facing the drum 410, the protrusion extending toward the drum 410, and located at a side of the sidewall facing away from the surface to be cleaned. In other embodiments, the wiper 511 and the waste water collecting channel 510 may be two separate members, for example, the wiper 511 may be a scraper extending in the axial direction of the drum 410, which may be fixedly or detachably connected to the waste water collecting channel 510 or the waste water tank 600, as long as it can abut against the mop of the drum 410 to squeeze out waste water from the mop and guide the waste water into the waste water collecting channel 510. In some embodiments, the cleaning device may be provided with only the wiper 511 without the waste water collecting trough 510, e.g. the wiper 511 may abut the mop to squeeze out waste water from the mop and direct the waste water directly into the waste bin 600.

Referring to fig. 8-9, in an embodiment of the present application, the lift assembly is capable of switching the drum 410 between a lowered position and a raised position, and the wiper 511 is configured to remain in abutment with the drum 410 when both are in the raised position and the lowered position. Thus, no matter the drum 410 is in the ascending position or the descending position, the water scraping part 511 can scrape off sewage in the mop as long as the drum 410 rotates, so that the mop can be cleaned, and the real-time self-cleaning of the mop can be realized. Further, referring to fig. 10, in the embodiment of the present application, the drum 410 in the raised position and the drum 410 in the lowered position are partially intersected in space, and the wiper 511 is located at an intersection position b of the drum 410 in the raised position and the drum 410 in the lowered position, that is, a position where the mop of the drum 410 in the raised position and the mop of the drum 410 in the lowered position are spatially overlapped, and the wiper 511 is disposed at the intersection position b so that the drum 410 is abutted with the drum 410 in both the raised position and the lowered position.

In some embodiments, the wiper 511 may be configured to abut against only the mop of the drum 410 in the lowered position, but not contact with the mop of the drum 410 in the raised position, so that when the drum 410 cleans the surface to be cleaned, the dirt and other dirt in the mop can be scraped off, and the real-time self-cleaning of the mop is realized during the cleaning of the surface to be cleaned by the drum 410, which may effectively improve the cleaning effect of the drum 410 on the surface to be cleaned. In some embodiments, the wiper 511 may be configured to only abut against the mop of the drum 410 in the raised position, but not contact the mop of the drum 410 in the lowered position, so that after this configuration, the drum 410 in the lowered position may be controlled to clean the surface to be cleaned at a slower rotational speed (e.g., one revolution per 3 minutes or one revolution per 5 minutes, etc.), after one revolution of the drum 410, the drum 410 is switched to the raised position by the lifting assembly, the drum 410 is controlled to rotate at a high speed for a plurality of revolutions to effect cleaning of the mop by the wiper 511, after cleaning of the mop is completed, the drum 410 is switched to the lowered position by the lifting assembly, and cleaning of the surface to be cleaned continues at the slower rotational speed, continuously repeating the above-described process until cleaning of the surface to be cleaned is completed. Compared with the roller 410, the cleaning mode always keeps a higher rotating speed to clean the surface to be cleaned, so that the energy consumption of the cleaning equipment can be effectively reduced, and the cruising time of the cleaning equipment can be increased.

Referring to fig. 6-8, in the embodiment of the present application, the cleaning apparatus further includes an attaching portion 512, where the attaching portion 512 is located below the wiper portion 511, and has an arc surface for keeping the mop of the drum 410 attached, and the arc surface can make the water leaked or overflowed from the lower side of the wiper portion 511 absorbed into the mop again (absorbed by the mop), so as to avoid the sewage from leaking from the lower side of the wiper portion 511 onto the surface to be cleaned, thereby affecting the cleaning effect and user experience. Note that the fitting may include abutting with slight interference. In the embodiment of the present application, the attaching portion 512 is a side wall of the sewage collecting tank 510 facing the drum 410, a surface of the side wall facing the drum 410 is formed into an arc surface, and the arc surface is the same as or similar to the arc of the circumferential side surface of the drum 410, and is attached to the drum 410 when the drum 410 is at the descending position, and the wiper portion 511, the attaching portion 512 and the sewage collecting tank 510 are integrally formed. In some embodiments, the engaging portion 512 and the waste water collecting tank 510 may be two separate members, for example, the engaging portion 512 may be an arc plate having the same or close to the curvature of the circumferential side of the drum 410, which may be integrally formed with the wiper portion 511, or may be fixedly or detachably connected to the waste water collecting tank 510 or the waste water tank 600, as long as it can engage with the mop of the drum 410 under the wiper portion 511 so that the water leaked or overflowed under the wiper portion 511 is absorbed again into the mop. In some embodiments, the fitting portion 512 may be provided separately from the wiper portion 511.

Referring to fig. 6 to 8, in the embodiment of the present application, the sewage collecting assembly 500 further includes a filter member detachably provided in the sewage collecting tank 510 for filtering the sewage scraped by the wiper 511 so as not to block the sewage outlet 513 or the sewage inlet 611. The filter includes a screen support 520 and a screen 530. The filter screen bracket 520 is detachably connected to the sewage collecting tank 510, specifically, the sidewall of the filter screen bracket 520 is overlapped and/or fastened to the opening edge of the top of the sewage collecting tank 510, so that the sewage scraped by the scraping part 511 first enters the filter screen bracket 520, then enters the sewage collecting tank 510, and finally enters the sewage tank 600 through the sewage outlet 513 at the bottom of the sewage collecting tank 510. The filter screen 530 is fixedly or detachably disposed on the filter screen bracket 520, and is used for filtering the sewage entering the filter screen bracket 520, and filtering and retaining the impurities such as hair and particulate matters in the sewage on the filter screen 530, so as to avoid blocking the sewage outlet 513 and the pipeline inside the sewage tank 600. In some embodiments, screen 530 may be integrally injection molded with screen support 520, and screen 530 may act as a bottom wall of screen support 520; in some embodiments, the screen 530 may be removably attached to the screen support 520 by a snap fit, screw connection, or the like. In this embodiment, the user may conveniently remove the filter screen holder 520 (or further remove the filter screen 530 in the filter screen holder 520) to clean or replace the filter screen 530. In some embodiments, the screen support 520 and the screen 530 described above may not be provided in the sewage collection tank 510. In some embodiments, the filter holder 520 and the filter 530 may be replaced with other filter members disposed in the sewage collecting tank 510, and the filter members may be disposed as required by those skilled in the art.

Referring to fig. 8, in the embodiment of the present application, the rotation direction a of the drum 410 (anticlockwise in fig. 8) is opposite to the rotation direction of the traveling wheel 210 (or the track wheel) (the rotation direction of the traveling wheel 210 is clockwise in fig. 8), so that the dirt scraped from the drum 410 by the scraping part 511 can smoothly enter the dirt collecting tank 510, and the dirt on the drum 410 can be effectively prevented from flowing onto the cleaning surface, and besides, the relative movement speed between the drum 410 and the surface to be cleaned is superimposed, the contact time between the mop and the surface to be cleaned is increased, and the cleaning effect of the surface to be cleaned can be effectively improved. In some embodiments, the rotational direction a of the drum 410 (counterclockwise in fig. 8) may be the same as the traveling direction of the cleaning device, i.e., the same as the rotational direction of the traveling wheel 210, i.e., the rotational direction of the traveling wheel 210 in fig. 8 may be configured to rotate in a clockwise direction, in which case the sewage collecting assembly may be provided in front of the drum 410.

That is, the sewage tank 600 can be inserted into the apparatus main body 100 only in a first direction, and the sewage tank 600 inserted into the apparatus main body 100 can be separated from the apparatus main body 100 only in a second direction opposite to the first direction. In an embodiment of the present application, the protrusion 110 may have a receiving space therein, which may be used to receive clear water, i.e., the protrusion 110 may be a part of the clear water tank 800 provided on the apparatus body 100. Therefore, the space on the cleaning device can be fully utilized through the structure arrangement, so that the cleaning device structure is more compact. In the embodiment of the present application, the first and second guide grooves 6211 and 6221 are symmetrically disposed on the first and second convex hulls 621 and 622, and respectively, the first and second guide protrusions 112 and 115 are symmetrically disposed on the first and second sidewalls 111 and 115.

In the embodiment of the present application, the first limiting surface 113 and the second limiting surface 117 are also symmetrically disposed on both sides of the first sidewall 111 and the second sidewall 115. In some embodiments, the tank 600 may be configured to: when the sewage tank 600 is inserted into the protrusion 110 of the apparatus main body 100, the upper surface of the first guide protrusion 112 abuts against the inner wall surface of the upper side of the first guide groove 6211, and the lower surface of the first guide protrusion 112 abuts against the inner wall surface of the lower side of the first guide groove 6211; the upper surface of the second guide protrusion 116 abuts against the upper side of the second guide groove 6221, and the lower surface of the second guide protrusion 116 abuts against the inner wall surface of the lower side of the second guide groove 6221, so that the movement of the sewage tank 600 in the up-down direction of the cleaning apparatus is completely restricted. Note that, the present application is not limited to the above-described embodiments. The abutting in the present application may be close fitting or close fitting (with a small gap).

When the first lock 624 and/or the second lock 625 are in the locked position, the first lock 624 and/or the second lock 625 are engaged with the corresponding first lock slot 114 and/or second lock slot 118; when the first latch 624 and/or the second latch 625 are in the unlatched position, the first latch 624 and/or the second latch 625 are separated from the respective first latch slot 114 and/or second latch slot 118. When the sewage tank 600 is plugged into the device main body 100 and the first lock 624 or the second lock 625 is at the locking position, the first lock 624 or the second lock 625 is engaged with the corresponding first lock groove 114 and second lock groove 118, so that the sewage tank 600 plugged into the device main body 100 is limited to leave the device main body 100 along the second direction, and the sewage tank 600 plugged into the device main body 100 is completely limited on the device main body 100. When the sewage tank 600 is plugged into the device main body 100 and the first latch 624 and the second latch 625 are both in the unlocked position, the first latch 624 and the second latch 625 are separated from the first latch slot 114 and the second latch slot 118, and the sewage tank 600 plugged into the device main body 100 can leave the device main body 100 along the second direction. That is, by switching the first latch 624 and the second latch 625 between the locking position and the unlocking position, the sewage tank 600 can be easily attached to the apparatus body 100 or detached from the apparatus body 100.

It should be noted that in other embodiments, the number of the latch assemblies may be one, three or more, that is, the number of the latches and the latch grooves may be one or three or more, and those skilled in the art may set the number as required. The application improves the stability of the connection between the sewage tank 600 and the device main body 100 by arranging the two lock catches and the two lock catch grooves, and improves the redundancy to a certain extent, even if the matching between one lock catch and the corresponding lock catch groove fails (namely, when one lock catch is in a locking state and the other lock catch is in an unlocking state), the other lock catch and the corresponding lock catch groove can effectively limit the sewage tank 600 inserted into the device main body 100 to leave the device main body 100 along the second direction. In other embodiments, two or more latch assemblies may be provided on each of the first and second convex hulls 621 and 622.

The latch assembly further includes a support member 6245 and an elastic member 6246, wherein the support member 6245 is detachably disposed inside the apparatus body 100 and below the latch body 6241, specifically, a screw groove 6214 is disposed inside the first convex hull 621, a through hole matching the screw groove 6214 is disposed on the support member 6245, and a screw 6247 is passed through the through hole to engage with the screw groove 6214 so as to detachably connect the support member 6245 to the first convex hull 621. The elastic member 6246 is disposed between the supporting member 6245 and the latch body 6241, and is configured to push the first latch 624 to move upwards by self-elastic force until the upper side of the guiding portion 6244 abuts against the top of the first convex hull 621, so that the first latch 624 is in the locking position. When the first latch 624 is in the locked position, the key portion 6243 and the buckling portion 6242 protrude outside the first convex hull 621. When the key portion 6243 is pressed, the elastic member 6246 is compressed (or deformed), the first lock 624 can be switched from the locked position to the unlocked position, and when the first lock 624 is in the unlocked position, the key portion 6243 and the buckling portion 6242 are received in the first convex hull 621 and do not protrude from the upper surface of the first convex hull 621. When the key portion 6243 is no longer pressed, the elastic member 6246 can push the first latch 624 to return from the unlocked position to the locked position.

When the sewage tank 600 is plugged into the device main body 100, during the process that the buckling part 6242 enters the first locking groove 114, the guiding surface can be firstly abutted against the device main body 100 to push the first locking buckle 624 to move downwards, so as to compress the elastic piece 6246, and the first locking buckle 624 can be switched from the locking position to the unlocking position; when the engagement portion 6242 on the first lock 624 in the unlock position moves to the first lock groove 114, the guide surface is separated from the apparatus body 100, and the elastic member 6246 urges the first lock 624 to switch from the unlock position to the lock position. The guide surface is provided so that the user does not need to manually press the key part 6243 to hold it in the unlock position during the insertion of the sewage tank 600 to the apparatus body 100.

Referring to fig. 23, when the sewage tank 600 is plugged into the apparatus main body 100 and the key portion 6243 is pressed to place the first latch 624 in the unlocking position, the key portion 6243 and the latch portion 6242 are received in the first convex hull 621, and the latch portion 6242 received in the first convex hull 621 does not protrude from the upper surface of the first convex hull 621, so that the latch portion 6242 is separated from the first latch groove 114, and movement of the sewage tank 600 in the second direction (i.e., the left direction in fig. 24) is not restricted, and the sewage tank 600 can leave the apparatus main body 100 in the second direction.

In the embodiment of the present application, the first lock 624 and the second lock 625 are disposed in the first convex hull 621 and the second convex hull 622, so that a part of the dead space at the upper part of the sewage tank 600 is fully utilized, occupation of the inner space of the lower housing 610 is avoided, and the effective volume of the sewage tank 600 is increased. And the distance (span) between the first latch 624 and the second latch 625 provided on the first convex hull 621 and the second convex hull 622 is greater than the distance (span) between the first guide groove 6211 and the second guide groove 6221, so that the sewage tank 600 can be more stably and reliably limited, and is not easy to shake. When a user installs the sewage tank 600 on the apparatus main body 100, the user only needs to plug the sewage tank 600 into the apparatus main body along the first direction, so that the first lock 624 and the second lock 625 are buckled with the first lock groove 114 and the second lock groove 118; when the user removes the sewage tank 600 attached to the apparatus main body 100 from the apparatus main body 100, the user simply and conveniently moves the sewage tank 600 in the second direction by pressing the key portion 6243 to disengage the first latch 624 and the second latch 625 from the first latch groove 114 and the second latch groove 118.

The sewage discharging assembly is connected with the sewage tank 600, and a drain port 618 communicating with the accommodation space in the sewage tank 600 is provided at the sewage tank 600 for pumping air outside the sewage tank 600 to the sewage tank 600, so that positive pressure is generated in the sewage tank 600, so that sewage in the accommodation space in the sewage tank 600 is discharged out of the sewage tank 600 through the drain port 618.

Specifically, the first check valve 713 is located at an end of the outlet pipe 712 remote from the sewage pump 710, the first check valve 713 may be a duckbill valve or other suitable check valve that only allows the air from the outlet pipe 712 to be discharged unidirectionally outwardly therethrough into the ambient air (i.e., the first check valve 713 allows the air to be discharged outwardly from the outlet pipe 712 therethrough while restricting the passage of external air into the outlet pipe 712 therethrough), and may provide a resistance to the air discharged therethrough such that it may block the air from being discharged therethrough to some extent when the sewage pump 720 is in operation, thereby enhancing the capacity of the sewage pump 720 to create positive pressure within the sewage tank 600. In some embodiments, the air outlet pipe 712 may not be disposed at the air outlet of the soil pump 710, and the first check valve 713 is directly connected to the air outlet of the soil pump 710.

The outlet pipe of the sewage pump 720 includes a first outlet pipe 722 and a second outlet pipe 723, and a second check valve 724 is located between the first outlet pipe 722 and the second outlet pipe 723, which allows only the gas from the first outlet pipe 722 to pass through it unidirectionally into the second outlet pipe 723 (i.e., the second check valve 724 allows the gas to flow from the sewage pump 720 to the three-way joint 730 and then into the receiving space in the sewage tank 600 while restricting the gas from flowing from the three-way joint 730 to the sewage pump 720), and which can create a certain resistance to the gas entering the second outlet pipe 723 so that it can block the gas from passing through it into the second outlet pipe 723 to a certain extent (i.e., block the gas from the sewage pump 720 from entering the sewage pump 710) when the sewage pump 710 is operated, thereby enhancing the capacity of the sewage pump 710 to generate negative pressure in the sewage tank 600. In an embodiment of the present application, the soil pump 710 and the soil pump 720 are configured to operate at different times to avoid interaction. In some embodiments, the three-way joint 730 may be replaced by a three-way control valve, where the three-way control valve may controllably connect the collecting pipe 740 to the air outlet pipe of the sewage pump 720 (and not to the air inlet pipe 711) or connect the collecting pipe 740 to the air inlet pipe 711 (and not to the air outlet pipe of the sewage pump 720), that is, the three-way control valve may connect the air inlet pipe 711 to the connection port 6212 or connect the air outlet pipe of the sewage pump 720 to the connection port 6212, and there is no need to provide the first check valve 713 and the second check valve 724 on the air inlet pipe 711 and the air outlet pipe of the sewage pump 720.

At this time, a first check valve 713 and a second check valve 724 may be respectively provided on the air inlet pipe 711 and the air outlet pipe of the sewage pump 720 to enhance the capacity of the sewage pump 710 to generate positive and negative pressure in the sewage tank 600.

Referring to fig. 25-38, in the embodiment of the application, a gas inlet and outlet passage, a suction fluid passage, and a discharge fluid passage are provided in the sewage tank 600.

Specifically, the connection port 6212 communicates with an accommodation space for accommodating sewage in the sewage tank 600 through a gas inlet and outlet passage. The gas inlet and outlet passage includes a vent connection port 6215, a first vent interface 616, a receiving chamber 615, a filter assembly 631, a second vent interface 617, a vent tube 632, a vent bracket 633, and a water inlet check valve assembly 634. Specifically, the ventilation connection port 6215 is located on the first convex hull 621 and is in communication with the connection port 6212, the first ventilation insertion port 616, the accommodating cavity 615, the filter assembly 631, the second ventilation insertion port 617, the ventilation tube 632 and the ventilation bracket 633 are located on the lower housing 610, and the first ventilation insertion port 616 is inserted into the ventilation connection port 6215.

Referring to fig. 30-31, the filter assembly 631 includes a housing having a first vent 6311 and a second vent 6312 and a first sponge filter 6313 positioned within the housing. The receiving cavity 615 communicates with the first vent interface 616 and the second vent interface 617, and when the filter assembly 631 is inserted into the receiving cavity 615, the first vent 6311 is in communication with the first vent interface 616 and the second vent 6312 is in communication with the second vent interface 617. The first end of the vent pipe 632 is inserted into the second vent insertion port 617, and the second end of the vent pipe 632 is inserted into the first end of the vent bracket 633 having a gas passage therein.

The second convex hull 622 is provided with a mounting groove on the upper side that mates with the inlet check valve assembly 634, into which the inlet check valve assembly 634 can be inserted in a top-down direction. Referring to fig. 32-35, the water inlet check valve assembly 634 includes a first lower cover 6341 and a first upper cover 6342, the first upper cover 6342 is connected to the first lower cover 6341 (e.g. by a snap connection), the first lower cover 6341 and the first upper cover 6342 are respectively provided with a first chamber and a second chamber which are not communicated with each other, a cylindrical ventilation port 6343 and a hollowed ventilation opening 6344 are provided on a lower side wall (i.e. a side wall facing to the lower casing 610) of the first lower cover 6341 at the first chamber, the ventilation port 6343 and the ventilation opening 6344 are communicated through a space in the second chamber, and a filter screen 6346 and a second sponge filter element 6345 covering the ventilation opening 6344 are provided in the first chamber. A water inlet port 6347 and a water outlet port 6349 are provided on a lower side wall of the first lower cover 6341 at the second chamber (i.e., on a side wall facing the lower housing 610), a water inlet check valve 6348 is provided in the water outlet port 6349, and the water inlet port 6347 and the water outlet port 6349 are communicated through a space in the first chamber. A second end of the breather pipe 632 is inserted into the breather port 6343, and the breather opening 6344 communicates with a containing space for containing sewage in the sewage tank 600. So that when the sewage pump 710 is operated, the air in the accommodating space for accommodating sewage in the sewage tank 600 leaves the sewage tank 600 through the air vent opening 6344, the filter screen 6346, the second sponge filter element 6345, the air vent port 6343, the air vent bracket 633, the second air vent port 617, the second air vent hole 6312, the first sponge filter element 6313, the first air vent hole 6311, the first air vent port 616, the air vent connection port 6215, and the connection port 6212 in this order.

In this embodiment, the arrangement of the first sponge filter 6313, the second sponge filter 6345 and the filter screen 6346 can effectively filter sewage, and prevent large particles and flock in the sewage from entering the sewage suction pump 710 to damage the sewage suction pump 710. The first and second sponge cartridges 6313, 6345 may be cellular reticulated foam or other suitable filter-capable device, as may be desired by one skilled in the art. When the sewage pump 720 is operated, gas flows in a direction opposite to that when the sewage pump 710 is operated to enter the accommodating space for accommodating sewage inside the sewage tank 600 from outside the sewage tank 600, and a description thereof will not be repeated. It should be noted that, in the embodiment of the present application, the connection of each component in the gas inlet and outlet passage is a sealed connection. In some embodiments, one of the first and second sponge cartridges 6313, 6345 may be omitted.

In the embodiment of the present application, the sewage suction liquid path is used for communicating the sewage inlet 611 with the accommodating space in the sewage tank 600 for accommodating sewage, so that when negative pressure is generated in the sewage tank 600, sewage in the sewage collecting tank 510 can enter the accommodating space in the sewage tank 600 for accommodating sewage through the sewage inlet 611 and the sewage suction liquid path. Specifically, the soil pick-up fluid path includes a connector 641, a water inlet pipe 642, a plug connector 6222 and a water inlet check valve assembly 634. The inside of the connection element 641 is provided with a circulation passage, the first end of the connection element 641 is connected with the sewage inlet 611, the second end of the connection element 641 is inserted into the first end of the water inlet pipe 642, and the water inlet pipe 642 is communicated with the sewage inlet 611 through the connection element 641. The second end of the water inlet pipe 642 is inserted into the first end of the insertion port 6222. The plug-in port 6222 is located on the second convex hull 622, when the water inlet check valve assembly 634 is plugged into the corresponding installation groove on the second convex hull 622, the water inlet port 6347 on the water inlet check valve assembly 634 is plugged into the second end of the plug-in port 6222, the water inlet port 6347 and the water outlet 6349 are communicated with the space in the first chamber of the water inlet check valve 6348 assembly, and the water outlet 6349 is communicated with the containing space in the sewage tank 600 for containing sewage. The inlet check valve 6348 allows fluid from the inlet port 6347 to pass unidirectionally therethrough into the receiving space within the tank 600 for receiving sewage (i.e., the inlet check valve assembly 634 allows fluid from the sewage inlet 610 (i.e., from the sewage collection tank 510) to pass therethrough to the receiving space within the tank 600 for receiving sewage while restricting the reverse flow of fluid therethrough), and the inlet check valve 6348 may be a duckbill valve or other suitable check valve. The duckbill valve is made of a flexible material such as rubber and comprises a duckbill valve inlet and a duckbill valve outlet, and only allows fluid (liquid or gas) to flow from the duckbill valve inlet to the duckbill valve outlet, when the fluid has a tendency to flow in the reverse direction, the duckbill valve port portion is in a closed state due to the pressure of the fluid, thereby blocking the reverse flow of the fluid. Thus, when the sewage suction pump 710 operates, the sewage in the sewage tank 600 is at a negative pressure (i.e., when the pressure in the accommodating space in the sewage tank 600 for accommodating sewage is less than the ambient pressure outside the sewage tank 600), the sewage in the sewage collecting tank 510 can sequentially enter the accommodating space in the sewage tank 600 for accommodating sewage through the sewage inlet 611, the connection 641, the water inlet pipe 642, the plug-in port 6222, the water inlet interface 6347, and the water inlet check valve 6348 under the action of the external ambient pressure. In the embodiment of the application, all the parts in the dirt absorbing liquid path are connected in a sealing way. In embodiments of the present application, the inlet check valve assembly 634 is configured to simultaneously achieve the inlet and outlet (and filtering) and one-way inlet functions, and in other embodiments, the inlet check valve assembly 634 is configured to achieve the inlet and outlet (and filtering) and one-way inlet functions, where the inlet check valve assembly 634 is configured to split the inlet and outlet (and filtering) and one-way inlet functions into two separate components.

In the embodiment of the present application, the sewage drain path is used to communicate the receiving space for receiving sewage in the sewage tank 600 with the drain port 618, so that when a positive pressure is generated in the sewage tank 600, the sewage received in the sewage tank 600 can flow to the drain port 618 through the sewage drain path and be discharged to the outside of the sewage tank 600 through the drain port 618. Specifically, connection 651, outlet pipe 652, plug 6216, first drain plug 6217, outlet check valve assembly 653, second drain plug 6181. The connection member 651 has a flow passage therein, a first end thereof having an opening at the bottommost portion of the receiving space for receiving sewage in the sewage tank 600, and a second end thereof inserted into the first end of the water outlet pipe 652. The second end of the water outlet pipe 652 is inserted into the first end of the plug connector 6216, and the plug connector 6216 is located on the first convex hull 621. The upper side of the first convex hull 621 is provided with a mounting groove matched with the water outlet one-way valve component 653, and the water outlet one-way valve component 653 can be inserted into the mounting groove along the direction from top to bottom. Referring to fig. 36-38, the outlet check valve assembly 653 includes a second lower cover 6531 and a second upper cover 6532, where the second upper cover 6532 is removably attached to the second lower cover 6531 (e.g., by snap-fit attachment), and a chamber is defined between the second lower cover 6531 and the second upper cover 6532. The lower side (i.e., the side facing the lower housing 610) of the second lower cover 6531 is provided with a first water outlet port 6533 and a second water outlet port 6435, a water outlet check valve 6534 is provided in the second water outlet port 6435, and the first water outlet port 6533 and the second water outlet port 6435 are communicated through the chamber. When the water outlet check valve component 653 is inserted into the mounting groove, the first water outlet 6533 is inserted into the second end of the insertion port 6216. The first convex hull 621 is further provided with a first drain plug connector 6217, and when the water outlet check valve component 653 is plugged in the mounting groove, the second water outlet connector 6435 abuts against the first end of the first drain plug connector 6217 to form communication. The outlet check valve 6534 only allows fluid from the first outlet port 6533 to flow therethrough to the first drain plug 6217 (i.e., the outlet check valve assembly 653 allows fluid from the receiving space within the tank 600 for receiving wastewater to flow therethrough to the drain 618 while restricting fluid from flowing in a reverse direction therethrough), the outlet check valve 6534 may be a duckbill valve or other suitable check valve. When the first boss 621 is connected to the lower housing 610, the first drain plug connector 6217 is plugged into a second drain plug connector 6181 provided on the lower housing 610, the second drain plug connector 6181 communicating with the drain port 618. Thus, when the sewage pump 720 is operated and the pressure in the sewage tank 600 is positive (i.e., when the pressure in the accommodating space for accommodating sewage in the sewage tank 600 is greater than the ambient pressure outside the sewage tank 600), sewage in the sewage collecting tank 510 can be discharged from the sewage tank 600 through the connector 651, the water outlet pipe 652, the plug-in port 6216, the first water discharge plug-in port 6217, the first water discharge port 6533, the water discharge one-way valve 6534, the first water discharge plug-in port 6217, the second water discharge plug-in port 6181, and the water discharge port 618 in this order under the effect of the pressure. In the embodiment of the application, all the parts in the sewage disposal liquid path are connected in a sealing way. Referring to fig. 39, in some embodiments, a diaphragm valve 6536 is further provided in the outlet check valve assembly 653, where the diaphragm valve 6536 is located in the chamber between the second lower cover 6531 and the second upper cover 6532 and covers the upper end of the first outlet port 6533. The diaphragm valve 6536 is a flexible member made of rubber, and includes a diaphragm valve opening, and the diaphragm valve opening is normally closed. When water pressure passes through, the diaphragm valve opening can be opened, and a certain blocking effect can be achieved on water flow. Thus, when the siphon action occurs, as long as the pressure in the sewage tank 600 is not positive pressure, the sewage in the sewage tank 600 cannot continuously flow outwards against the obstruction of the diaphragm valve 6536, so that the water in the sewage tank 600 can be effectively prevented from continuously flowing outwards due to the siphon action.

The cleaning device of the present application can prevent the sewage suction pump 710 and the sewage discharge pump 720 from directly contacting with sewage by generating negative pressure in the sewage tank 600 and positive pressure in the sewage tank 600, thereby reducing the fault that the impurities such as hair, particles, etc. in the sewage cause blockage or even damage to the pump, and greatly improving the service life of the pump. And the sewage can be automatically discharged by generating positive pressure in the sewage tank 600 through the sewage pump 720, the cleaning robot can be controlled to actively discharge the sewage at the appointed position where the cleaning robot advances (for example, when the cleaning robot advances to a base station or a floor drain), the use scene of the robot is widened, the user is not required to manually clean the sewage, the operation of the user is effectively reduced, the sewage is not required to be discharged by means of a specific sewage discharging structure on the base station, and the cost of the base station can be effectively reduced.

In the embodiment of the present application, when the soil pump 710 is operated, the water inlet check valve 6348 is opened and the water outlet check valve 6534 is closed; when the sewage pump 720 is operated, the water inlet check valve 6348 is closed and the water outlet check valve 6534 is opened. Therefore, when the sewage suction pump 710 or the sewage pump 720 works, good sealing performance can be kept in the sewage tank 600, and the working effects of the sewage suction pump 710 and the sewage pump 720 are improved.

In the embodiment of the present application, the water inlet check valve assembly 634, the water outlet check valve assembly 653 and the filter assembly 631 are detachably disposed on the sewage tank 600, and these assemblies may be damaged or fail after a certain period of use due to contact with sewage, so that a user can conveniently detach these components for cleaning or replacement. In the embodiment of the present application, the water inlet check valve assembly 634 and the water outlet check valve assembly 653 are respectively inserted into the mounting grooves on the second convex hull 622 and the first convex hull 621, when the sewage tank 600 is inserted into the main body 100 of the apparatus, the first limiting surfaces 113 and the second limiting surfaces 117 on both sides of the first sidewall 111 and the second sidewall 115 cover the mounting grooves corresponding to the water outlet check valve assembly 653 and the water inlet check valve assembly 634 respectively, so that the water inlet check valve assembly 634 and the water outlet check valve assembly 653 are completely limited in the mounting grooves, and do not loosen or fall off when the cleaning apparatus works.

Referring to fig. 25-28, in an embodiment of the present application, the cleaning apparatus further includes a water-full detection float 660 and a water-full detection sensor. The water fullness detecting float 660 is located in the sewage tank 600 and can float on the surface of the sewage, and is lifted and lowered synchronously (i.e., is lifted and lowered synchronously) with the lifting of the sewage surface. When the sewage contained in the sewage tank 600 reaches a set capacity, the water fullness detecting float 660 may float up to a preset height. A water-full detection sensor is provided in the sewage tank 600 or in the apparatus main body 100 for detecting whether the water-full detection float 660 rises to a preset height. In the embodiment of the present application, the water-full detection float 660 includes a water-full sensing magnet 612, and the water-full detection sensor is a hall sensor, and when the water-full detection float 660 rises to a preset height, the water-full sensing magnet 612 triggers the hall sensor to output a sensing signal; when the water full detection float 660 does not rise to a preset height, the hall sensor is not triggered and does not output a sensing signal. A controller is also provided in the cleaning apparatus, and the controller may be connected to the water-full detection sensor and the soil pick-up pump 710 to control the soil pick-up pump 710 to stop operating when receiving a sensing signal outputted from the water-full detection sensor. In the embodiment, the ventilation bracket 633 is configured to have an extension extending in the up-down direction, and the water fullness detecting float 660 is sleeved on the extension extending in the up-down direction of the ventilation bracket 633, so that it is limited to be movable only in the up-down direction according to the change of the sewage level in the sewage tank 600, so as to better trigger the water fullness detecting sensor.

In the embodiment of the present application, a communicating pipe (not shown in the drawing) is further disposed in the sewage tank 600, the communicating pipe is a U-shaped pipe or other pipe fitting with a suitable shape, and is located in the cavity of the sewage tank 600, one end of the communicating pipe is located in the second accommodating space (near the top of the second accommodating space) in the first convex hull 621, the other end of the communicating pipe is located in the third accommodating space (near the top of the third accommodating space) in the first convex hull 621, and the gas in the second accommodating space and the gas in the third accommodating space can circulate through the communicating pipe, so that the gas pressure in the first convex hull 621 and the gas pressure in the second convex hull 622 remain balanced.

Referring to fig. 24, in the embodiment of the present application, the clean water tank 800 is fixedly disposed in the apparatus main body 100, and the protrusion 110, which is inserted and engaged with the sewage tank 600, is formed on the outer wall surface of the clean water tank 800, so that the cleaning apparatus has a compact structure, and the size of the cleaning apparatus is reduced. In some embodiments, the fresh water tank 800 may also be detachably disposed on the apparatus body 100 by a screw or a buckle.

In the embodiment of the present application, the fresh water pump assembly 900 includes a fresh water pump 910, a water inlet pipe 920 and a water outlet pipe 930, the fresh water pump 910 is connected to the fresh water tank 800 through the water inlet pipe 920, and the fresh water pump 910 is connected to the fresh water inlet 421 on the lifting support through the water outlet pipe 930, so that the fresh water pump 910 in the fresh water tank 800 can be sent into the cavity in the lifting support, and then evenly sprayed onto the mop of the drum 410 through the fresh water outlet 422 on the lifting support, so as to wet the mop.

When the cleaning device according to the embodiment of the application works, the driving motor drives the driving wheel 210 to rotate so as to drive the cleaning device to travel on the surface to be cleaned, the roller motor drives the roller 410 at the descending position to rotate around the central axis of the roller 410, and the mop on the roller 410 is in surface contact with the surface to be cleaned, so that liquid dirt on the surface to be cleaned can be absorbed, and a dirt removing effect is generated by friction with the surface to be cleaned.

The clear water pump 910 can pump clear water in the clear water tank 800, and the clear water pump 910 is sent into a cavity in the lifting bracket, and evenly sprays the clear water to the mop of the roller 410 through the clear water outlet 422 on the lifting bracket, so that the mop can be wetted.

During the rotation of the drum 410, the scraping part 511 is abutted with the mop of the drum 410 to scrape out the sewage and other dirt in the mop, the scraped sewage flows into the sewage collecting tank 510, and the filter screen 530 in the sewage collecting tank 510 filters the foreign matters such as hair and particles so as to remain on the filter screen 530. The attachment portion 512 remains attached to the mop so that water leaking or spilling under the wiper portion 511 is again absorbed into (taken away by) the mop, thereby avoiding leakage of dirty water from under the wiper portion 511 onto the surface to be cleaned.

The sewage suction pump 710 is controlled to work, air in the sewage tank 600 is pumped out, negative pressure is formed in the sewage tank 600, and sewage in the sewage collecting tank 510 enters the sewage tank 600 through the sewage inlet 611 and the sewage suction liquid path for storage. The sewage suction pump 710 generates negative pressure in the sewage tank 600 to timely suck the sewage in the sewage collecting tank 510 into the sewage tank 600 for storage, so that the sewage basically cannot overflow from the sewage collecting tank 510 to fall onto the surface to be cleaned, and the sewage is prevented from polluting the surface to be cleaned again. And users do not need to frequently wash and replace the mop, so that user experience and cleaning efficiency are effectively improved.

When the sewage in the sewage tank 600 reaches a set capacity, the sewage suction pump 710 and the clean water pump 910 are controlled to stop working, the cleaning apparatus is controlled to travel to a base station or other designated location, and the sewage pump 720 is controlled to pump external air into the sewage tank 600, so that positive pressure is formed in the sewage tank 600, and thus the sewage in the sewage tank 600 is discharged to the base station or other location suitable for receiving the sewage outside the sewage tank 600 through the sewage outlet. After the sewage is discharged, the cleaning device can be controlled to continuously clean the surface to be cleaned through the process.

The cleaning device of the present application can prevent the sewage suction pump 710 and the sewage discharge pump 720 from directly contacting with sewage by generating negative pressure in the sewage tank 600 and positive pressure in the sewage tank 600, thereby reducing the fault that the impurities such as hair, particles, etc. in the sewage cause blockage or even damage to the pump, and greatly improving the service life of the pump.
