Cleaning system

[0001] Cross-reference to related applications

[0002] The present application claims priority to the Chinese patent application No. 202421823403.1, filed on July 30, 2024, and entitled "Cleaning system", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present disclosure relates to the technical field of cleaning equipment, in particular to a cleaning system. BACKGROUND

[0004] A cleaning robot is a product capable of realizing automatic sweeping, dust collection and mopping functions. It has gradually replaced manpower and is widely used in cleaning places in family and commercial scenarios due to its high cleaning efficiency and good cleaning effect.

[0005] After completing the work of cleaning the ground, the cleaning robot returns to the robot parking space of the robot base station and washes the mop of the cleaning robot, and injects clean water or a mixture of clean water and cleaning liquid into the clean water box of the robot. At present, the injection can be realized by the power device of the base station or the power device of the robot itself.

[0006] Through the power device of the robot base station, such as a water pump, clean water or a mixture is extracted from the base station and injected into the robot clean water box. When the clean water box is full, an electrical signal is triggered. The robot needs to send the electrical signal to the base station in a wireless form, so that the base station water pump stops working. This process relies on the wireless communication between the base station and the robot. If the communication is unstable, the base station cannot receive the signal of the full water in the robot clean water box in time, and the base station water pump continues to work, which will cause the clean water in the clean water box to overflow or flow out from the water injection port.

[0007] And through the power device of the robot itself to realize the injection, an additional air pump needs to be installed on the robot body, which occupies the space of the robot body and is not conducive to the miniaturization design of the robot.

DETAILED DESCRIPTION

[0033] In order to enable a more complete understanding of the above-mentioned objects, features and advantages of the present disclosure, the schemes of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0034] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present disclosure, but the present disclosure can also be implemented in other manners different from those described herein; obviously, the embodiments described in the specification are only a part of the embodiments of the present disclosure, and not all the embodiments.

[0035] Embodiment One

[0036] As shown in FIGS. 1-4, the cleaning system according to the embodiments of the present disclosure comprises a base station 100 and a main machine 200. The base station 100 comprises a clean water tank 11 and a water supply column 19 communicating with the clean water tank 11, and the main machine 200 comprises a clean water box 32, a dirty water box 33 and a first suction device 34. The side wall of the main machine 200 is provided with a water receiving port 321 which is connected with the water supply column 19, and the water receiving port 321 communicates with the clean water box 32.

[0037] The first suction device 34 has a first suction branch 341 and a second suction branch 342. The first suction branch 341 communicates with the dirty water box 33 to suck the dirty water generated during cleaning into the dirty water box 33. The second suction branch 342 communicates with the clean water box 32 to suck the water in the clean water tank 11 through the water supply column 19 and the water receiving port 321 into the clean water box 32.

[0038] That is, when the water receiving port 321 and the water supply column 19 are connected, the first suction device 34 can suck the water in the clean water tank 11 of the base station 100 through the second suction branch 342 into the clean water box 32 of the main machine 200. When the main machine 200 is cleaning, the first suction device 34 can suck the dirty water generated during cleaning into the dirty water box 33 of the main machine 200 through the first suction branch 341. The dirty water generated during cleaning is mainly the dirty water scraped from the wiping member 24 by a scraping strip (not shown) on the main machine 200, and the dirty water enters a dirty water collecting tank (not shown). The dirty water in the dirty water collecting tank is sucked into the dirty water box 33 under the suction of the first suction device 34.

[0039] For example, the first suction device 34 can be a gas pump or a vacuum pump, which is used to vacuum the dirty water box 33 or the clean water box 32. When the water receiving port 321 and the water supply column 19 are connected, the first suction device 34 can vacuum the clean water box 32 through the second suction branch 342, so that a negative pressure is generated in the clean water box 32, and the clean water in the clean water tank 11 enters the clean water box 32 through the water supply column 19 and the water receiving port 321 under the action of the negative pressure. When the main machine 200 is cleaning, the first suction device 34 can vacuum the dirty water box 33 through the first suction branch 341, so that a negative pressure is generated in the dirty water box 33, and the dirty water enters the dirty water box 33 under the action of the negative pressure. It should be noted that the vacuuming of the dirty water box 33 through the first suction branch 341 and the vacuuming of the clean water box 32 through the second suction branch 342 are generally performed separately. That is, the first suction device 34 vacuums the dirty water box 33 through the first suction branch 341 when the main machine 200 is cleaning, and vacuums the clean water box 32 through the second suction branch 342 when the main machine 200 enters the base station 100 and the water supply column 19 and the water receiving port 321 are connected.

[0040] In one embodiment, as shown in FIG. 7 and FIG. 8, the chassis of the main machine 200 is provided with a mop 24 and an exhaust hole 25, the exhaust hole 25 is connected to the air outlet of the first suction device 34, and the exhaust hole 25 is located at the top of the mop 24. Connecting the air outlet of the first suction device 34 to the exhaust hole 25 provided on the chassis of the main machine 200, and the exhaust hole 25 is located at the top of the mop 24, so that when the first suction device 34 is filled with water or water vapor is generated in the first suction device 34, the water or water vapor can be discharged from the exhaust hole 25 and dripped on the mop 24, avoiding direct dripping on the ground and affecting the cleaning effect.

[0041] The first suction device 34 can also be a centrifugal fan. When the water inlet 321 and the water supply column 19 are connected, the suction force generated by the first suction device 34 passes through the second air suction branch 342, the water purification box 32, the water inlet 321, the water supply column 19 in turn, and acts on the clean water tank 11 of the base station 100. The clean water in the clean water tank 11 enters the water purification box 32 through the water supply column 19 and the water inlet 321 under the action of the suction force of the first suction device 34. When the main machine 200 is cleaning, the suction force generated by the first suction device 34 passes through the first air suction branch 341 and the sewage box 33 in turn, and acts on the suction port of the main machine 200. The sewage at the suction port enters the sewage box 33 under the action of the suction force.

[0042] Further, referring to FIG. 1 to FIG. 4, the above-mentioned main machine 200 further comprises a third communication valve 35, the third communication valve 35 comprises a first interface and two second interfaces, the first interface is connected to the air inlet of the first suction device 34, and the two second interfaces are connected to the water purification box 32 and the sewage box 33 respectively. The third communication valve 35 can selectively make the first interface conductive with one of the second interfaces.

[0043] Understandably, the second interface connected to the water purification box 32 forms the above-mentioned second air suction branch 342, and the second interface connected to the sewage box 33 forms the above-mentioned first air suction branch 341. The third communication valve 35 can selectively make the first interface conductive with the second interface connected to the water purification box 32, or make the first interface conductive with the second interface connected to the sewage box 33.

[0044] Exemplarily, in a specific implementation, the above-mentioned third communication valve 35 is a three-way electromagnetic valve. The three-way electromagnetic valve is controlled by the controller of the main machine 200 to selectively make the first interface conductive with one of the second interfaces.

[0045] Referring to FIGS. 1-4, the base station 100 further comprises a cleaning liquid tank 12, a communication valve 13, and a base station chassis 14 capable of carrying the main machine 200. The communication valve 13 comprises four interfaces, wherein the first interface is connected to the cleaning liquid output pipe 121 of the cleaning liquid tank 12, the second interface is connected to the water column 19, the third interface is connected to the clean water tank 11, and the fourth interface is connected to the water outlet of the base station chassis 14. The communication valve 13 can selectively connect any at least two of the four interfaces. The third interface is connected to the clean water tank water supply pipe 111 of the clean water tank 11.

[0046] It should be noted that the cleaning liquid and / or clean water sprayed from the water outlet of the base station chassis 14 can clean the wiping element 24 on the main machine 200, and can also achieve self-cleaning of the base station chassis 14.

[0047] Further, referring to FIGS. 1-4, the base station 100 further comprises a second extraction device 15 capable of extracting the cleaning liquid in the cleaning liquid tank 12. The output of the second extraction device 15 is connected to the cleaning liquid output pipe 121.

[0048] It can be understood that the second extraction device 15 can extract the cleaning liquid in the cleaning liquid tank 12 and deliver it to the cleaning liquid output pipe 121, and then output it externally through the communication valve 13.

[0049] For example, the second extraction device 15 can be selected from, but not limited to, a peristaltic pump, a centrifugal pump, a gear pump, and a diaphragm pump.

[0050] Further, referring to FIGS. 1-4, the base station 100 further comprises an on-off valve 16. The inlet of the on-off valve 16 is connected to the second interface of the communication valve 13, and the outlet of the on-off valve 16 is connected to the water column 19. The inlet of the on-off valve 16 is connected to an on-off valve water inlet pipe 161, which is connected to the second interface of the communication valve 13. The outlet of the on-off valve 16 is connected to an on-off valve water outlet pipe 162, which is connected to the water column 19.

[0051] It can be understood that the on-off valve 16 can control the conduction or disconnection of its inlet and outlet. In this way, when the water column 19 and the water inlet 321 are disconnected, the inlet and outlet of the on-off valve 16 can be kept in a disconnected state to prevent water leakage of the water column 19. When the water column 19 and the water inlet 321 are connected, the inlet and outlet of the on-off valve 16 are connected. At this time, if the second interface and the first interface of the communication valve 13 are connected, cleaning liquid can be added to the clean water box 32. If the second interface and the third interface of the communication valve 13 are connected, clean water can be added to the clean water box 32. If the second interface of the communication valve 13 is connected to the first interface and the third interface, clean water and cleaning liquid can be added to the clean water box 32 at the same time.

[0052] Exemplarily, the on-off valve 16 can be selected from, but is not limited to, a solenoid valve. The solenoid valve has an inlet and an outlet, and the inlet and the outlet of the solenoid valve are controlled by the controller of the main machine 200, for example, when the water column 19 and the water receiving port 321 are docked, the controller of the main machine 200 controls the inlet and the outlet of the solenoid valve to be on. When the water column 19 and the water receiving port 321 are undocked, the controller of the main machine 200 controls the inlet and the outlet of the solenoid valve to be off, so as to avoid the water column 19 from leaking.

[0053] Further, referring to FIGS. 1-4, the base station 100 further comprises a third pumping device 17, a water inlet pipe 171 of the third pumping device 17 is communicated with the fourth interface of the communication valve 13, and a water outlet pipe 172 of the third pumping device 17 is communicated with the water spraying port on the base station chassis 14.

[0054] Understandably, the third pumping device 17 can provide power for the cleaning liquid and / or the clean water to enter the base station chassis 14, or the third pumping device 17 can pump the cleaning liquid and / or the clean water to the base station chassis 14, so that the cleaning liquid and / or the clean water can be sprayed through the water spraying port to clean the mop 24 on the main machine 200 or to perform self-cleaning on the base station chassis 14.

[0055] Exemplarily, the third pumping device 17 can be selected from, but is not limited to, a water pump, a magnetic pump, a pneumatic diaphragm pump, a centrifugal pump, etc.

[0056] Further, referring to FIGS. 1-4, the base station 100 further comprises a sewage tank 18 and a fourth pumping device 20, the fourth pumping device 20 has a gas suction pipeline which is communicated with the sewage tank 18, so as to pump the sewage tank 18 to vacuum, so that the sewage on the base station chassis 14 enters the sewage tank 18.

[0057] Understandably, when the water spraying port of the base station chassis 14 sprays the cleaning liquid and / or the clean water to clean the mop 24 on the main machine 200, or to perform self-cleaning on the base station chassis 14, the fourth pumping device 20 can pump the sewage tank 18 to vacuum, so that the sewage tank 18 generates negative pressure, and the sewage on the base station chassis 14 is pumped into the sewage tank 18 under the action of the negative pressure in the sewage tank 18, so as to collect the sewage on the base station chassis 14. The sewage tank 18 and the sewage tank on the base station chassis 14 are communicated through a pipeline.

[0058] Continuing to refer to FIG. 4, the base station 100 further comprises a second muffling box 21 having a second muffling cavity, an exhaust pipeline of the fourth pumping device 20 is communicated with the second muffling cavity, and the second muffling box 21 has a second exhaust hole communicated with the second muffling cavity.

[0059] It can be understood that when the fourth extraction device 20 extracts the sewage tank 18, the exhaust gas enters the second muffling cavity for muffling, and then is discharged to the outside of the base station 100 through the second exhaust hole, so that the noise generated by the fourth extraction device 20 during operation can be avoided.

[0060] Exemplarily, the fourth extraction device 20 can be selected but is not limited to a gas pump, a centrifugal fan, a vacuum pump, an ion pump, etc.

[0061] Further, referring to FIG. 4, the host 200 further comprises a fifth extraction device 36 for extracting water in the clean water tank 32 of the host 200 to wet the mop 24. That is, the water inlet of the fifth extraction device 36 is connected to the clean water tank 32 through a pipeline, and the water outlet of the fifth extraction device 36 is connected to the mop 24 through a pipeline to keep the mop 24 wet during cleaning, thereby improving the cleaning effect.

[0062] Exemplarily, the fifth extraction device 36 can be selected but is not limited to a water pump.

[0063] Further, referring to FIG. 4, the host 200 further comprises a first muffling box 37 having a first muffling cavity, and the air outlet of the first extraction device 34 is connected to the first muffling cavity. The first muffling box 37 further has a first exhaust hole connected to the first muffling cavity. The first exhaust hole is located at the top of the mop 24.

[0064] It can be understood that when the first extraction device 34 extracts the sewage tank 33 or the clean water tank 32, the exhaust gas enters the first muffling cavity for muffling, and then is discharged to the outside of the host 200 through the first exhaust hole, so that the noise generated by the first extraction device 34 during operation can be avoided.

[0072] It should be noted that when the first suction device 34 is used to suck water from the water tank 32 through the second suction branch 342, the second suction device 15 is not working, that is, only clean water is added to the water tank 32 of the main machine 200, so that the cleaning liquid is not added to the water tank 32, thereby avoiding the formation of water marks on the ground during the cleaning process of the mop 24.

[0073] In addition, when the host 200 is located on the base station chassis 14, if the cleaning element 24 of the host 200 is cleaned, if the cleaning element 24 is reversed, the third extraction device 17 and the second extraction device 15 are both operated to clean the cleaning element 24 by the mixed liquid of the clean water and the cleaning liquid. If the cleaning element 24 is forward, only the third extraction device 17 is operated, that is, the cleaning element 24 is cleaned by the clean water, at this time, the cleaning liquid on the cleaning element 24 can be cleaned. Among them, the forward and reverse rotation of the cleaning element 24 is a relative concept, which means that the rotation direction of the cleaning element 24 is opposite in the two cases, and the specific rotation direction of the cleaning element 24 when it is forward and reverse is set according to actual needs.

[0074] It should be noted that the communication valve 13 at this time can be selected as a four-way pipe, which is beneficial to reduce the cost. Of course, it can also be selected as a solenoid valve.

[0075] Exemplarily, in another specific implementation manner, the communication valve 13 can selectively make any two interfaces of the four interfaces thereof communicate.

[0076] If the first interface and the second interface are communicated, when the water column 19 is connected with the water inlet 321 and the inlet and the outlet of the on-off valve 16 are communicated, the first extraction device 34 extracts the clean water box 32 by the second air extraction branch 342, and the cleaning liquid in the cleaning liquid tank 12 can be added into the clean water box 32 of the host 200 through the water column 19.

[0077] If the first interface and the third interface are communicated, the cleaning liquid in the cleaning liquid tank 12 can be introduced into the clean water tank 11 through the second extraction device 15 to mix the cleaning liquid and the clean water.

[0078] If the first interface and the fourth interface are communicated, the cleaning liquid can be delivered to the water outlet of the base station chassis 14 through the third extraction device 17 to clean the cleaning element 24 of the host 200 or realize self-cleaning of the base station chassis 14.

[0079] If the second interface and the third interface are communicated, when the water column 19 is connected with the water inlet 321 and the inlet and the outlet of the on-off valve 16 are communicated, the first extraction device 34 extracts the clean water box 32 by the second air extraction branch 342, and the clean water in the clean water tank 11 can be added into the clean water box 32 of the host 200 through the water column 19.

[0080] If the third interface and the fourth interface are communicated, the clean water can be delivered to the water outlet of the base station chassis 14 through the third extraction device 17 to clean the cleaning element 24 of the host 200 or realize self-cleaning of the base station chassis 14.

[0081] Exemplarily, in another specific implementation manner, the communication valve 13 can selectively make any three interfaces of the four interfaces thereof communicate with each other.

[0082] If the first interface, the second interface and the third interface are in communication with each other, when the water column 19 is connected to the water inlet 321 and the inlet and the outlet of the on-off valve 16 are in communication, the clean water in the clean water tank 11 can be added into the clean water box 32 of the main machine 200 through the water column 19 if the first suction device 34 sucks the clean water box 32 through the second suction branch 342. If the second suction device 15 works at this time, the cleaning liquid and the clean water mixed can be added into the clean water box 32 of the main machine 200 through the water column 19.

[0083] If the first interface, the second interface and the fourth interface are in communication with each other, when the water column 19 is connected to the water inlet 321 and the inlet and the outlet of the on-off valve 16 are in communication, the cleaning liquid in the cleaning liquid tank 12 can be added into the clean water box 32 of the main machine 200 through the water column 19 if the first suction device 34 sucks the clean water box 32 through the second suction branch 342 and the second suction device 15 works at the same time.

[0084] When the third suction device 17 and the second suction device 15 work, the cleaning liquid can be delivered to the water outlet of the base station bottom plate 14 to clean the mop 24 of the main machine 200 or realize self-cleaning of the base station bottom plate 14. When the third suction device 17 works, the first suction device 34 can work or not work, and the inlet and the outlet of the on-off valve 16 can be in communication or disconnected.

[0085] If the first interface, the third interface and the fourth interface are in communication, when the third suction device 17 and the second suction device 15 work, the mixed liquid of the cleaning liquid and the clean water can be delivered to the water outlet of the base station bottom plate 14 to clean the mop 24 of the main machine 200 or realize self-cleaning of the base station bottom plate 14. If only the third suction device 17 works, the clean water can be delivered to the water outlet of the base station bottom plate 14 to clean the mop 24 of the main machine 200 or realize self-cleaning of the base station bottom plate 14.

[0086] If the second interface, the third interface and the fourth interface are in communication with each other, when the water column 19 is connected to the water inlet 321 and the inlet and the outlet of the on-off valve 16 are in communication, the clean water in the clean water tank 11 can be added into the clean water box 32 of the main machine 200 through the water column 19 if the first suction device 34 sucks the clean water box 32 through the second suction branch 342. When the third suction device 17 works, the clean water can be delivered to the water outlet of the base station bottom plate 14 to clean the mop 24 of the main machine 200 or realize self-cleaning of the base station bottom plate 14. When the third suction device 17 works, the first suction device 34 can work or not work, and the inlet and the outlet of the on-off valve 16 can be in communication or disconnected.

[0087] Embodiment two

[0088] As shown in FIG. 6, the cleaning system provided by the embodiment of the present disclosure includes a base station 100 and a main machine 200. The base station 100 includes a clean water tank 11 and a water supply column 19 communicating with the clean water tank 11, and the main machine 200 includes a clean water box 32, a dirty water box 33 and a first suction device 34. The side wall of the main machine 200 is provided with a water receiving port 321 which is connected with the water supply column 19, and the water receiving port 321 communicates with the clean water box 32.

[0089] The first suction device 34 has a first suction branch 341 and a second suction branch 342. The first suction branch 341 communicates with the dirty water box 33 to vacuum the dirty water box 33 to collect the dirty water generated during cleaning. The second suction branch 342 communicates with the clean water box 32 to vacuum the clean water box 32 so that the clean water in the clean water tank 11 enters the clean water box 32 through the water supply column 19 and the water receiving port 321.

[0090] That is, when the water receiving port 321 and the water supply column 19 are connected, the first suction device 34 can vacuum the clean water box 32 through the second suction branch 342, so that the clean water box 32 generates negative pressure, and the clean water in the clean water tank 11 enters the clean water box 32 under the action of negative pressure through the water supply column 19 and the water receiving port 321. When the main machine 200 is cleaning, the first suction device 34 can vacuum the dirty water box 33 through the first suction branch 341, so that the dirty water box 33 generates negative pressure, and the dirty water enters the dirty water box 33 under the action of negative pressure. The dirty water generated during cleaning is mainly the dirty water scraped from the wiping piece 24 by the scraping strip on the main machine 200, which enters the dirty water box 33 under the action of negative pressure in the dirty water box 33.

[0091] It should be noted that the vacuuming of the dirty water box 33 by the first suction device 34 through the first suction branch 341 and the vacuuming of the clean water box 32 by the first suction device 34 through the second suction branch 342 are generally performed separately, that is, the first suction device 34 vacuums the dirty water box 33 through the first suction branch 341 when the main machine 200 is cleaning, and vacuums the clean water box 32 through the second suction branch 342 when the main machine 200 enters the base station 100 and the water supply column 19 and the water receiving port 321 are connected.

[0092] Exemplarily, the first suction device 34 can be a gas pump. The gas pump is arranged in the main machine 200 and used to vacuum the dirty water box 33 or the clean water box 32.

[0093] Further, referring to FIG. 6, the host 200 further comprises a third communication valve 35, which comprises a first interface and two second interfaces, the first interface is in communication with the air outlet of the first extraction device 34, and the two second interfaces are in communication with the clean water box 32 and the sewage box 33 respectively. The third communication valve 35 can selectively make the first interface conductive with one of the second interfaces.

[0094] Understandably, the second interface in communication with the clean water box 32 forms the second air extraction branch 342, and the second interface in communication with the sewage box 33 forms the first air extraction branch 341. The third communication valve 35 can selectively make the first interface conductive with the second interface in communication with the clean water box 32, or make the first interface conductive with the second interface in communication with the sewage box 33.

[0095] Exemplarily, in a specific implementation, the third communication valve 35 is a three-way electromagnetic valve. The three-way electromagnetic valve is controlled by the controller of the host 200 to selectively make the first interface conductive with one of the second interfaces.

[0096] Referring to FIG. 6, the base station 100 further comprises a cleaning liquid tank 12 and a first communication valve 22, the first communication valve 22 comprises three interfaces, the first interface is in communication with the cleaning liquid tank 12, the second interface is in communication with the clean water tank 11, and the third interface is in communication with the water supply column 19. The first communication valve 22 can selectively make any at least two of the three interfaces conductive.

[0097] Further, the base station 100 further comprises a base station chassis 14 and a second communication valve 23, the second communication valve 23 comprises three interfaces, the fourth interface is in communication with the third interface of the first communication valve 22, the fifth interface is in communication with the water supply column 19, and the sixth interface is in communication with the water outlet of the base station chassis 14. The second communication valve 23 can make any at least two of the three interfaces conductive.

[0098] Further, referring to FIG. 6, the base station 100 further comprises a second extraction device 15 capable of extracting the cleaning liquid in the cleaning liquid tank 12, and the output port of the second extraction device 15 is in communication with the cleaning liquid output pipe 121.

[0099] Understandably, the second extraction device 15 can extract the cleaning liquid in the cleaning liquid tank 12 and deliver it into the cleaning liquid output pipe 121, and then output it outward through the first communication valve 22.

[0100] Exemplarily, the second extraction device 15 can be, but is not limited to, a peristaltic pump.

[0101] Further, referring to Fig. 6, the base station 100 further comprises a on-off valve 16, the inlet of the on-off valve 16 is connected to the fifth interface of the second communication valve 23, and the outlet of the on-off valve 16 is connected to the water supply column 19. Understandably, the on-off valve 16 can control the on or off of the inlet and the outlet thereof, so that the inlet and the outlet of the on-off valve 16 can be kept in the off state when the water supply column 19 and the water receiving port 321 are not docked, so as to avoid the water leakage of the water supply column 19. When the water supply column 19 and the water receiving port 321 are docked, the inlet and the outlet of the on-off valve 16 are on, at this time, if the fifth interface of the second communication valve 23 is connected to the fourth interface of the second communication valve 23, the third interface of the first communication valve 22 is connected to the first interface of the first communication valve 22 (at this time, the fourth interface of the second communication valve 23 is connected to the third interface of the first communication valve 22), the cleaning liquid can be added into the water purifying box 32. If the fifth interface of the second communication valve 23 is connected to the fourth interface of the second communication valve 23, the third interface of the first communication valve 22 is connected to the second interface of the first communication valve 22 (at this time, the fourth interface of the second communication valve 23 is connected to the third interface of the first communication valve 22), the clean water can be added into the water purifying box 32. If the fifth interface of the second communication valve 23 is connected to the fourth interface of the second communication valve 23, and the third interface of the first communication valve 22 is connected to the first interface and the second interface of the first communication valve 22 (at this time, the fourth interface of the second communication valve 23 is connected to the third interface of the first communication valve 22), the clean water and the cleaning liquid can be added into the water purifying box 32 at the same time.

[0102] Exemplarily, the on-off valve 16 can be selected but is not limited to a solenoid valve. The solenoid valve has an inlet and an outlet, and the solenoid valve is controlled by the controller of the host 200, for example, when the water supply column 19 and the water receiving port 321 are docked, the controller of the host 200 controls the inlet and the outlet of the solenoid valve to be on. When the water supply column 19 and the water receiving port 321 are not docked, the controller of the host 200 controls the inlet and the outlet of the solenoid valve to be off, so as to avoid the water leakage of the water supply column 19.

[0103] Further, referring to Fig. 6, the base station 100 further comprises a third extraction device 17, the water inlet pipe 171 of the third extraction device 17 is connected to the sixth interface of the second communication valve 23, and the water outlet pipe 172 of the third extraction device 17 is connected to the water spraying port on the base station bottom plate 14.

[0104] Understandably, the third extraction device 17 can provide the power for the cleaning liquid and / or the clean water to enter into the base station bottom plate 14, or the third extraction device 17 can extract the cleaning liquid and / or the clean water to the base station bottom plate 14, so that the cleaning liquid and / or the clean water can be sprayed through the water spraying port to clean the wiping member 24 on the host 200 or to perform the self-cleaning of the base station bottom plate 14.

[0105] Exemplarily, the third extraction device 17 can be selected but is not limited to a water pump.

[0106] Further, referring to FIG. 6, the base station 100 further comprises a sewage tank 18 and a fourth extraction device 20. The fourth extraction device 20 has an air extraction pipeline which is communicated with the sewage tank 18 to extract air from the sewage tank 18 so that sewage on the base station chassis 14 enters the sewage tank 18.

[0107] Understandably, when the water spraying port of the base station chassis 14 sprays cleaning liquid and / or clean water to clean the mopping piece 24 on the main machine 200 or to perform self-cleaning on the base station chassis 14, sewage is generated. The fourth extraction device 20 can extract air from the sewage tank 18 to generate negative pressure in the sewage tank 18. Under the action of the negative pressure in the sewage tank 18, the sewage on the base station chassis 14 is extracted into the sewage tank 18, thereby realizing collection of the sewage on the base station chassis 14. The sewage tank 18 and the sewage tank on the base station chassis 14 are communicated through a pipeline.

[0108] Continuing to refer to FIG. 6, the base station 100 further comprises a second muffling box 21 having a second muffling cavity. An exhaust pipeline of the fourth extraction device 20 is communicated with the second muffling cavity. The second muffling box 21 has a second exhaust hole which is communicated with the second muffling cavity.

[0109] Understandably, when the fourth extraction device 20 extracts air from the sewage tank 18, the exhaust gas enters the second muffling cavity to be muffled and then is discharged to the outside of the base station 100 through the second exhaust hole, thereby avoiding generation of large noise when the fourth extraction device 20 works.

[0110] Exemplarily, the fourth extraction device 20 can be selected but is not limited to a gas pump.

[0111] Further, referring to FIG. 6, the main machine 200 further comprises a fifth extraction device 36. The fifth extraction device 36 is used to extract water in the clean water tank 32 of the main machine 200 to wet the mopping piece 24. That is, a water inlet of the fifth extraction device 36 is communicated with the clean water tank 32 through a pipeline. A water outlet of the fifth extraction device 36 delivers water to wet the mopping piece 24 through a pipeline, so that the mopping piece 24 can be kept in a wet state when cleaning the ground, thereby improving the cleaning effect.

[0112] Exemplarily, the fifth extraction device 36 can be selected but is not limited to a water pump.

[0113] Continuing to refer to FIG. 6, the main machine 200 further comprises a first muffling box 37 having a first muffling cavity. An exhaust branch of the first extraction device 34 is communicated with the first muffling cavity. The first muffling box 37 further has a first exhaust hole which is communicated with the first muffling cavity.

[0114] It can be understood that when the first extraction device 34 performs vacuum extraction on the sewage box 33 or the clean water box 32, the discharged gas enters the first sound attenuation cavity for sound attenuation, and then is discharged to the outside of the main machine 200 through the first exhaust hole, so that the noise generated by the first extraction device 34 during operation can be avoided.

[0115] In this embodiment, the first communication valve 22 can make any two of its three interfaces communicate, or make two of its three interfaces communicate with each other. The second communication valve 23 can make any two of its three interfaces communicate, or make two of its three interfaces communicate with each other.

[0116] For example, in a specific implementation, with reference to FIG. 6, two of the three interfaces of the first communication valve 22 are in communication, and two of the three interfaces of the second communication valve 23 are in communication.

[0117] In a case, when water needs to be added to the clean water box 32 of the main machine 200, the water supply column 19 is connected to the water receiving port 321, the on-off valve 16 makes its inlet and outlet communicate, and the first extraction device 34 performs vacuum extraction on the clean water box 32 through the second air extraction branch 342. If the second extraction device 15 does not work at this time, the clean water in the clean water tank 11 enters the clean water box 32. If the second extraction device 15 works at this time, the clean water in the clean water tank 11 and the cleaning liquid in the cleaning liquid tank 12 are mixed and then enter the clean water box 32.

[0118] In a second case, if only the third extraction device 17 works, the clean water in the clean water tank 11 enters the water spraying port of the base station chassis 14, and at this time, the mop 24 of the main machine 200 can be cleaned or the base station chassis 14 can be self-cleaned.

[0119] In a third case, if the third extraction device 17 and the second extraction device 15 work at the same time, the clean water in the clean water tank 11 and the cleaning liquid in the cleaning liquid tank 12 are mixed and then enter the water spraying port of the base station chassis 14, and at this time, the mop 24 of the main machine 200 can be cleaned or the base station chassis 14 can be self-cleaned.

[0120] In a fourth case, the water supply column 19 is connected to the water receiving port 321, the on-off valve 16 makes its inlet and outlet communicate, and the first extraction device 34 and the third extraction device 17 work at the same time. If the second extraction device 15 works at this time, the first extraction device 34 performs vacuum extraction on the clean water box 32 through the second air extraction branch 342, the mixture of clean water and cleaning liquid enters the clean water box 32, and the third extraction device 17 extracts the mixture of clean water and cleaning liquid to the water spraying port of the base station chassis 14. If the second extraction device 15 does not work at this time, the first extraction device 34 extracts the clean water to the clean water box 32, and the third extraction device 17 extracts the clean water to the water spraying port of the base station chassis 14.

[0121] The working states of the third extraction device 17 and the first extraction device 34 are independent of each other. When the first extraction device 34 is working, the third extraction device 17 can work or not work. Similarly, when the third extraction device 17 is working, the first extraction device 34 can work or not work. Similarly, when the third extraction device 17 is working, the inlet and the outlet of the on-off valve 16 can be in the open state or the closed state.

[0122] It should be noted that when the first extraction device 34 extracts the water tank 32 through the second air extraction branch 342, the second extraction device 15 does not work, that is, only clean water is added to the water tank 32 of the main machine 200, so as to avoid adding cleaning liquid to the water tank 32, thereby avoiding that the mop 24 generates water marks on the ground during the cleaning process.

[0123] In addition, when the main machine 200 is located on the base 14, if the mop 24 of the main machine 200 is cleaned, if the mop 24 is reversed, the third extraction device 17 and the second extraction device 15 work, and the mop 24 is cleaned by the mixture of clean water and cleaning liquid. If the mop 24 is forward, only the third extraction device 17 works, that is, the mop 24 is cleaned by clean water, and at this time, the cleaning liquid on the mop 24 can be cleaned. The forward and reverse rotation of the mop 24 is a relative concept, which means that the rotation directions of the mop 24 in the two cases are opposite, and the specific rotation directions of the forward and reverse rotation of the mop 24 are set according to actual needs.

[0124] It should be noted that the first communication valve 22 and the second communication valve 23 at this time can be selected as a three-way pipe, which is beneficial to reduce the cost. Of course, at least one of the first communication valve 22 and the second communication valve 23 can also be selected as a solenoid valve.

[0125] Exemplarily, in another specific implementation, in the case that the first communication valve 22 can selectively make the two interfaces thereof in communication, when the first interface and the third interface are in communication, the cleaning liquid can be transported, and when the second interface and the third interface are in communication, the clean water can be transported. When the first interface and the second interface are in communication, the cleaning liquid can be added to the clean water tank 11.

[0126] Firstly, it is assumed that the three interfaces of the second communication valve 23 are in communication with each other at this time. The second communication valve 23 at this time can be selected as a three-way pipe, which is beneficial to reduce the cost. Of course, the second communication valve 23 can also be selected as a solenoid valve.

[0127] In the first case, the second interface and the third interface of the first communication valve 22 are in communication.

[0128] When the inlet and outlet of the on-off valve 16 are connected, the water column 19 and the water outlet 321 are connected, and only the first pumping device 34 works, and the second pumping branch 342 is used to pump the clean water box 32, the clean water in the clean water tank 11 enters the clean water box 32 through the on-off valve 16, the water column 19 and the water outlet 321. When the first pumping device 34 works, the third pumping device 17 works, the clean water in the clean water tank 11 enters the clean water box 32 through the on-off valve 16, the water column 19 and the water outlet 321, and the clean water in the clean water tank 11 is pumped to the water outlet of the base station bottom plate 14 through the third pumping device 17. If only the third pumping device 17 works, the clean water in the clean water tank 11 is pumped to the water outlet of the base station bottom plate 14.

[0129] When the inlet and outlet of the on-off valve 16 are disconnected, if the third pumping device 17 works, the clean water in the clean water tank 11 is pumped to the water outlet of the base station bottom plate 14, which can clean the mop of the main machine 200 or realize self-cleaning of the base station bottom plate 14.

[0130] In the second case, the first interface and the third interface of the first communication valve 22 are connected.

[0131] When the inlet and outlet of the on-off valve 16 are connected, the water column 19 and the water outlet 321 are connected, and only the first pumping device 34 works, and the second pumping branch 342 is used to pump the clean water box 32, the clean water in the clean water tank 11 enters the clean water box 32 through the on-off valve 16, the water column 19 and the water outlet 321. When the first pumping device 34 works, the third pumping device 17 works, the clean water in the clean water tank 11 enters the clean water box 32 through the on-off valve 16, the water column 19 and the water outlet 321, and the clean water in the clean water tank 11 is pumped to the water outlet of the base station bottom plate 14 through the third pumping device 17. If only the third pumping device 17 works, the clean water in the clean water tank 11 is pumped to the water outlet of the base station bottom plate 14.

[0132] When the inlet and outlet of the on-off valve 16 are disconnected, if the third pumping device 17 works, the clean water in the clean water tank 11 is pumped to the water outlet of the base station bottom plate 14, which can clean the mop of the main machine 200 or realize self-cleaning of the base station bottom plate 14.

[0133] Secondly, it is assumed that the second communication valve 23 can selectively connect any two interfaces at this time. When the fourth interface and the fifth interface are connected, the water column 19 can be used to add clean water and / or cleaning liquid to the clean water box 32 of the main machine 200, and when the fourth interface and the sixth interface are connected, the water outlet of the base station bottom plate 14 can be used to spray clean water and / or cleaning liquid to clean the mop of the main machine 200 or realize self-cleaning of the base station bottom plate 14.

[0134] In the first case, the second and third interfaces of the first communication valve 22 are connected, and the fourth and sixth interfaces of the second communication valve 23 are connected. At this time, if the third extraction device 17 is working, the clean water in the clean water tank 11 is delivered to the water spraying port of the base plate 14 through the first and second communication valves 22 and 23.

[0135] In the second case, the second and third interfaces of the first communication valve 22 are connected, and the fourth and fifth interfaces of the second communication valve 23 are connected. At this time, if the inlet and outlet of the on-off valve 16 are connected, and the water supply column 19 and the water receiving port 321 are connected, the first extraction device 34 can extract the clean water tank 32 through the second air extraction branch 342, so that the clean water in the clean water tank 11 enters the clean water tank 32 through the first and second communication valves 22 and 23, the on-off valve 16, the water supply column 19 and the water receiving port 321.

[0136] In the third case, the first and third interfaces of the first communication valve 22 are connected, and the fourth and sixth interfaces of the second communication valve 23 are connected. At this time, if the third extraction device 17 is working, the second extraction device 15 is working, the cleaning liquid in the cleaning liquid tank 12 is delivered to the water spraying port of the base plate 14 through the first and second communication valves 22 and 23.

[0137] In the fourth case, the first and third interfaces of the first communication valve 22 are connected, and the fourth and fifth interfaces of the second communication valve 23 are connected. At this time, if the inlet and outlet of the on-off valve 16 are connected, and the water supply column 19 and the water receiving port 321 are connected, the second extraction device 15 is working, and the first extraction device 34 can extract the clean water tank 32 through the second air extraction branch 342, so that the cleaning liquid in the cleaning liquid tank 12 enters the clean water tank 32 through the first and second communication valves 22 and 23, the on-off valve 16, the water supply column 19 and the water receiving port 321.

[0138] Exemplarily, in another specific implementation, if the three interfaces of the first communication valve 22 are connected two by two, and the second communication valve 23 can selectively connect any two of its interfaces.

[0139] In the first case, the fourth interface and the fifth interface are connected, when the inlet and the outlet of the on-off valve 16 are connected, and the water column 19 and the water interface 321 are connected, if only the first extraction device 34 works, and the water tank 32 is vacuumized through the second extraction branch 342, at this time, the clean water in the clean water tank 11 can enter the water tank 32 through the first communication valve 22, the second communication valve 23, the on-off valve 16, the water column 19 and the water interface 321. If the first extraction device 34 works, the water tank 32 is vacuumized through the second extraction branch 342, and the second extraction device 15 works at the same time, at this time, the clean water in the clean water tank 11 and the cleaning liquid in the cleaning liquid tank 12 are mixed in the first communication valve 22, and then enter the water tank 32 through the second communication valve 23, the on-off valve 16, the water column 19 and the water interface 321.

[0140] It should be noted that, preferably, when the first extraction device 34 vacuumizes the water tank 32 through the second extraction branch 342, the second extraction device 15 does not work, that is, only clean water is added to the water tank 32 of the main machine 200, avoiding adding cleaning liquid to the water tank 32, so as to avoid the mop 24 from leaving water marks on the ground during cleaning.

[0141] In the second case, the fourth interface and the sixth interface are connected, at this time, the inlet and the outlet of the on-off valve 16 are connected or disconnected, if only the third extraction device 17 works, the clean water in the clean water tank 11 is transported to the water outlet of the base plate 14 to clean the mop 24 of the main machine 200 or realize self-cleaning of the base plate 14. If the third extraction device 17 works, and the second extraction device 15 works at the same time, the clean water in the clean water tank 11 and the cleaning liquid in the cleaning liquid tank 12 are mixed in the first communication valve 22, and then transported to the water outlet of the base plate 14 through the second communication valve 23 to clean the mop 24 of the main machine 200 or realize self-cleaning of the base plate 14.

[0142] It should be noted that, when the main machine 200 is located on the base plate 14, if the mop 24 of the main machine 200 is cleaned, if the mop 24 is reversed, the third extraction device 17 and the second extraction device 15 work, and the mop 24 is cleaned by the mixed liquid of the clean water and the cleaning liquid. If the mop 24 is forward, only the third extraction device 17 works, that is, the mop 24 is cleaned by the clean water, at this time, the cleaning liquid on the mop 24 can be cleaned. Among them, the forward and reverse rotation of the mop 24 is a relative concept, which means that the rotation direction of the mop 24 is opposite in the two cases, and the specific rotation direction of the mop 24 when it is forward and reverse is set according to actual needs.

[0143] In this implementation, the fifth interface and the sixth interface of the second communication valve 23 are connected, which has no practical significance, so it will not be described again.

[0144] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
