Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning robot. Background Art

[0002] A cleaning robot is a product that can automatically sweep, vacuum, and mop the floor. Due to its high cleaning efficiency and good cleaning effect, it has gradually replaced manpower and is widely used in cleaning places in homes and commercial scenarios.

[0003] When the cleaning robot is mopping the floor, it needs to intermittently use water from the clean water box to clean the floor and the mop, and at the same time, the wastewater from cleaning the mop needs to be collected in the wastewater box of the machine body.

[0004] In existing cleaning robots, an extraction device is typically used to collect wastewater generated by cleaning the mop into a wastewater box. The extraction device is equipped with an air inlet and an air outlet. The air inlet is connected to the wastewater box, and the air outlet is connected to the outside world, such as the exhaust port on the body. The extraction device stops working after receiving a signal that the wastewater box is full of water. If the water full detection structure fails or the body is severely shaken, the air inlet of the extraction device may draw liquid into the wastewater box. Even if all accessories are working normally, the extraction device may still draw water vapor from the wastewater box. The water vapor gathers into liquid in the channel of the extraction device. Under the action of airflow, the liquid passes through the air outlet of the extraction device and is discharged from the exhaust port on the body, causing the body to leak. At the same time, the liquid falling from the body will cause secondary pollution to the ground. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides a cleaning robot, in which the liquid discharged from the exhaust port is absorbed by the mopable part to solve the problem of secondary pollution to the ground.

[0011] Optionally, the machine body further has a top shell, a silencer cavity is provided between the bottom shell and the top shell, the silencer cavity is connected between the air outlet and the exhaust port, and the silencer cavity is provided close to the exhaust port.

[0012] Optionally, the sewage box is located above the wiping member, and the exhaust port is located at one end side of the sewage box.

[0013] Optionally, the mopping member comprises a bracket and a mop rotatably connected to the bracket, the mop has a base and bristles, and a gap of 2 to 5 mm is formed between the base and the bottom shell; and / or,

[0014] Optionally, the diameter of the exhaust port ranges from 4 to 6 mm.

[0015] Optionally, a water purification box is further provided in the machine body, and the first extraction device has a first air extraction branch and a second air extraction branch, the first air extraction branch is connected to the sewage box, and the second air extraction branch is connected to the water purification box.

[0016] Optionally, a third connecting valve is provided in the body, and the third connecting valve includes a first interface and two second interfaces, the first interface is connected to the air suction port of the first extraction device, and the two second interfaces are connected to the clean water box and the sewage box respectively; the third connecting valve is configured to selectively connect the first interface with one of the second interfaces.

[0017] The technical solution provided by the embodiments of the present application has the following advantages compared with the prior art:

[0018] The cleaning robot of the present application has a main body provided with a first extraction device pneumatically connected to a sewage box. The first extraction device is used to extract sewage generated when cleaning the floor or mopping the mop into the sewage box. The air outlet of the first extraction device is connected to an exhaust port provided on the bottom shell. When water enters the first extraction device or water vapor is generated in the first extraction device, the water or water vapor can be discharged from the exhaust port and drip directly onto the floor from the bottom shell, thereby preventing the liquid from contaminating other parts of the robot body. At the same time, the exhaust port is provided on the bottom shell, and the cleaning trajectory of the mopping member on the floor to be cleaned at least covers the movement trajectory of the exhaust port on the floor to be cleaned, so that the liquid dripping from the exhaust port can be absorbed by the mopping member, that is, the liquid dripping from the exhaust port can drip onto the mopping member and be directly absorbed by the mopping member; or after dripping onto the floor, it can be immediately absorbed by the mopping member after it passes by, thereby avoiding secondary contamination of the floor and affecting the cleaning effect.

[0019] In a further embodiment, the exhaust port is positioned above the mopping member, allowing the mopping member to clean the exhaust port in real time, preventing blockage. If the exhaust port is positioned elsewhere on the machine body, such as on the side, the presence of liquid in the exhaust port could contaminate the machine body with dust, affecting its appearance and also posing a risk of clogging. However, positioning the exhaust port above the mopping member not only prevents the appearance of the machine body but also allows the mopping member to scrape and clean the exhaust port in real time, removing any dust contaminated by the exhaust port. Furthermore, positioning the exhaust port directly above the mopping member allows liquid to be directly absorbed by the mopping member from the exhaust port, preventing the mopping member's cleaning trajectory from overlapping the exhaust port's movement trajectory during cornering, thereby improving cleaning efficiency.

[0040] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0042] Example 1

[0043] See also Figures 1 to 3 This embodiment provides a cleaning robot, which includes a body 31. The body 31 has a bottom shell 201. The bottom shell 201 is provided with a wiping member 38 for cleaning the ground. A sewage box 33 and a first extraction device 34 pneumatically connected to the sewage box 33 are provided in the body 31. The first extraction device 34 has an air inlet and an air outlet. The air inlet is connected to the sewage box 33, and the air outlet is connected to the exhaust port 39 located on the body 31. The wiping member 38 has a cleaning track A on the ground to be cleaned. The exhaust port 39 is located on the bottom shell 201. The exhaust port 39 has a moving track B relative to the ground to be cleaned, and the cleaning track A at least covers the moving track B.

[0044] The first extraction device 34 is used to extract sewage generated when cleaning the floor or cleaning the mop into the sewage box 33. The air outlet of the first extraction device 34 is connected to the exhaust port 39 provided above the wiping member 38. When water enters the first extraction device 34 or water vapor is generated in the first extraction device 34, the water or water vapor can be discharged from the exhaust port 39 and drip directly onto the floor from the bottom shell 201, thereby preventing the liquid from contaminating other parts of the body 31, such as the side walls.

[0045] The exhaust port 39 is disposed on the bottom shell 201, and the cleaning track A of the mopping member 38 on the ground to be cleaned at least covers the moving track B of the exhaust port 39 on the ground to be cleaned, so that the liquid dripping from the exhaust port 39 can be absorbed by the mopping member 38, that is, the liquid dripping from the exhaust port 39 can drip onto the mopping member 38 and be directly absorbed by the mopping member; or after dripping onto the ground, it can be immediately absorbed by the mopping member 38 after passing through, thereby avoiding secondary contamination of the ground and affecting the cleaning effect. It is understandable that the mopping member 38 can be a roller mop or a crawler mop. When the cleaning robot is cleaning, the roller mop or crawler mop rotates under the drive of the driving member, generating friction with the ground to remove dirt from the ground. At the same time, the first extraction device 34 sucks the dirt into the sewage box 33.

[0046] It is understood that the first extraction device 34 can be an air pump or a vacuum pump for vacuuming the sewage box 33. When the cleaning robot is cleaning, the first extraction device 34 can vacuum the sewage box 33, thereby generating a negative pressure in the sewage box 33, and the sewage enters the sewage box 33 under the action of the negative pressure.

[0047] The first extraction device 34 can also be a centrifugal fan. When the cleaning robot is cleaning, the suction force generated by the first extraction device 34 acts on the sewage suction port of the host 200 through the sewage box 33, and the sewage at the sewage suction port enters the sewage box 33 under the action of the suction force.

[0048] See also Figure 4 In a specific implementation, the exhaust port 39 is located above the wiping member 38 .

[0049] It is understood that the cleaning trajectory A of the wiping member 38 at least overlaps the movement trajectory B, that is, the wiping member 38 is at least partially located directly behind the exhaust port 39 in the forward direction of the robot body. When the cleaning robot is performing a cleaning operation, the movement trajectory of the robot body 31 can be divided into two types: one is straight along the forward direction of the robot body, and the other is deflected relative to the forward direction of the robot body, that is, turning. Because the wiping member 38 is at least partially located behind the exhaust port 39, if the exhaust port 38 is located near the edge of the robot body in the forward direction of the robot body, the cleaning trajectory A of the wiping member 38 may easily miss the movement trajectory B of the exhaust port 38 during the robot body turning. In this case, the exhaust port 38 can be located near the central axis of the robot body 31, or as close to the wiping member 38 as possible.

[0050] The vent 39 is arranged above the mopping member 38 so that the liquid dripping from the vent 39 can directly drip onto the mopping member 38 and be directly absorbed by the mopping member 38. The liquid dripping from the vent 39 can be processed more efficiently.

[0051] In a further implementation, the bottom shell 201 is provided with an upwardly recessed accommodating cavity 2011 for accommodating the wiping member 38 , and the top of the accommodating cavity 2011 is provided with the above-mentioned exhaust port 39 .

[0052] The bottom shell 201 is directly extended upward to form the accommodating cavity 2011 , and the accommodating cavity 2011 and the bottom shell 201 are integrally formed, thereby reducing body parts and connectors and simplifying the overall structure.

[0053] See also Figure 5 In another specific implementation, the body 31 has a front end and a rear end along the forward direction, the rubbing member 38 is located at the rear end of the body, the body 31 is also provided with a scraping member 40 that abuts against the rubbing member 38, and the exhaust port 39 is arranged close to the scraping member 40.

[0054] It is understood that the scraper 40 can be positioned in front of the wiping member 38, behind the wiping member 39, or obliquely to the side of the wiping member 38 to scrape dirt off the wiping member 38. When the scraper 40 is positioned in front of or obliquely in front of the wiping member 38, the wiping member 38 rotates toward the front of the machine body 31. When the scraper 40 is positioned behind or obliquely behind the wiping member 38, the wiping member 38 rotates toward the rear of the machine body 31. In this way, dirt or sewage scraped off by the scraper 40 can be absorbed by the sewage suction port located at the bottom of the machine body 31. The exhaust port 39 is positioned close to the scraper 40 so that liquid dripping from the exhaust port 39, after being absorbed by the wiping member 38, can be scraped off by the scraper 40 as quickly as possible and enter the sewage box 33 under the suction action of the first extraction device 34.

[0055] In a further implementation, a sewage receiving trough 41 is further provided at the rear end of the body 31 , the scraper 40 is located on one side of the sewage receiving trough 41 , and the sewage box 33 is provided with a sewage extraction pipe (sewage extraction pipe) extending into the sewage receiving trough 41 .

[0056] The sewage scraped off the wiping member by the scraping member 40 is directly collected in the sewage receiving trough 41 , and the sewage in the sewage receiving trough 41 is pumped into the sewage box 33 under the action of the suction force of the first suction device 34 .

[0057] See also Figure 6 and Figure 7 In another specific implementation, the body 31 further has a top shell 202, and a silencer cavity 42 is provided between the bottom shell 201 and the top shell 202. The silencer cavity 42 is connected between the air outlet and the exhaust port 39, and the silencer cavity 42 is provided close to the exhaust port 39.

[0058] When the first extraction device 34 performs the suction operation, the exhausted gas enters the silencer chamber 42 for silencing, and is then discharged to the outside of the main unit 200 through the exhaust port 39, which can reduce the noise generated when the first extraction device 34 is working.

[0059] In another specific implementation, the sewage box 33 is located above the wiping member 38 , and the exhaust port 39 is located at one end of the sewage box 33 .

[0060] The sewage box 33 is positioned above the wiping member 38 to reduce the distance between the sewage suction port and the sewage box 33, thereby improving the suction efficiency of the first extraction device 33. The exhaust port 39 is located at one end of the sewage box 33 to prevent vertical interference between the exhaust port and the sewage box 33, which would affect the layout of the exhaust pipeline.

[0061] In another specific implementation, the body 31 has a bottom shell 202, the mopping member 38 includes a bracket and a mop rotatably connected to the bracket, the mop has a base and planted bristles, and there is a gap of 2 to 5 mm between the base and the bottom shell 202; and / or, the diameter of the exhaust port 39 ranges from 4 to 6 mm.

[0062] A gap of 2 to 5 mm is provided between the base of the wiping member 38 and the bottom shell 202 to allow space for the bristles to form, preventing them from being pressed too tightly against the bottom shell 202 and causing significant resistance to the rotation of the wiping member 38. Furthermore, within this gap, the bristles can sweep the exhaust port 39 to remove dust that has accumulated therein. Setting the diameter of the exhaust port 39 between 4 and 6 mm also facilitates the cleaning of the exhaust port by the bristles of the wiping member 39.

[0063] See also Figure 8 In another specific implementation, a water purification box 32 is further provided in the body 31, and the first extraction device 34 has a first air extraction branch and a second air extraction branch. The first air extraction branch is connected to the sewage box 33, and the second air extraction branch is connected to the water purification box 32.

[0064] The first extraction device 34 can extract water from the base station into the clean water box 32 through the second air extraction branch. When the cleaning robot is cleaning, the first extraction device 34 can extract the sewage generated during cleaning into the sewage box 33 through the first air extraction branch. In this way, the first extraction device 34 can achieve the dual functions of extracting sewage and clean water, eliminating the need for an additional power device specifically for replenishing clean water in the clean water box, thereby reducing the space occupied by the power device.

[0065] In a further implementation, a third connecting valve (not shown in the figure) is provided in the main unit 31, and the third connecting valve includes a first interface and two second interfaces. The first interface is connected to the air suction port of the first extraction device, and the two second interfaces are respectively connected to the clean water box 32 and the sewage box 33; the third connecting valve is configured to selectively connect the first interface with one of the second interfaces.

[0066] Example 2

[0067] like Figures 9 to 12 As shown, an embodiment of the present application provides a cleaning system comprising a base station 100 and a main unit 200. The base station 100 comprises a clean water tank 11 and a water supply column 19 connected thereto. The main unit 200 comprises a clean water box 32, a dirty water box 33, and a first extraction device 34. A water inlet 321 is provided on the side wall of the main unit 200, which interfaces with the water supply column 19 and is connected to the clean water box 32.

[0068] The first extraction device 34 includes a first extraction branch and a second extraction branch. The first extraction branch is connected to the sewage box 33 to extract the sewage generated during cleaning into the sewage box 33. The second extraction branch is connected to the clean water box 32 to extract water from the clean water tank 11 into the clean water box 32 through the water supply column 19 and the water inlet 321.

[0069] That is, when the water inlet 321 is docked with the water supply column 19, the first extraction device 34 can extract water from the clean water tank 11 of the base station 100 through the water supply column 19 and the water inlet 321 via the second air extraction branch, into the clean water box 32 of the main unit 200. When the main unit 200 is being cleaned, the first extraction device 34 can use the first air extraction branch to extract the wastewater generated during cleaning into the wastewater box 33 of the main unit 200. The wastewater generated during cleaning primarily consists of wastewater scraped from the wiping member (not shown) by the scraping bar (not shown) on the main unit 200. This wastewater enters the sewage receiving trough, where it is drawn into the wastewater box 33 by the suction force of the first extraction device 34.

[0070] Illustratively, the first extraction device 34 can be an air pump or a vacuum pump, used to evacuate the sewage box 33 or the clean water box 32. When the water inlet 321 is docked with the water supply column 19, the first extraction device 34 can evacuate the clean water box 32 via the second air extraction branch, thereby generating a negative pressure within the clean water box 32. Under the action of the negative pressure, the clean water in the clean water tank 11 enters the clean water box 32 through the water supply column 19 and the water inlet 321. Furthermore, when the main unit 200 is being cleaned, the first extraction device can evacuate the sewage box 33 via the first air extraction branch, thereby generating a negative pressure within the sewage box 33, and the sewage enters the sewage box 33 under the action of the negative pressure.

[0071] It should be noted that the first extraction device 34 vacuums the sewage box 33 through the first air extraction branch and vacuums the water purification box 32 through the second air extraction branch generally separately, that is, the first extraction device 34 vacuums the sewage box 33 through the first air extraction branch when the host 200 is cleaning, and when the host 200 enters the base station 100, after the water supply column 19 and the water inlet 321 are connected, the first extraction device 34 can vacuum the water purification box 32 through the second air extraction branch.

[0072] In one embodiment, the chassis of the main unit 200 is provided with a mopping member and an exhaust port. The exhaust port is connected to the air outlet of the first extraction device 34 and is located at the top of the mopping member. The air outlet of the first extraction device 34 is connected to an exhaust port provided on the chassis of the main unit 200. The exhaust port is located at the top of the mopping member. When water enters the first extraction device 34 or water vapor is generated within the first extraction device 34, the water or water vapor is discharged through the exhaust port and drips onto the mopping member, preventing it from dripping directly onto the ground and affecting the cleaning effect.

[0073] The first extraction device 34 can also be a centrifugal fan. When the water inlet 321 is docked with the water supply column 19, the suction force generated by the first extraction device 34 sequentially passes through the second air extraction branch, the water purification box 32, the water inlet 321, and the water supply column 19, and acts on the clean water tank 11 of the base station 100. Under the suction force of the first extraction device 34, the clean water in the clean water tank 11 enters the clean water box 32 through the water supply column 19 and the water inlet 321. When the main unit 200 is being cleaned, the suction force generated by the first extraction device sequentially passes through the first air extraction branch and the sewage box 33, and acts on the sewage suction port of the main unit 200. The sewage at the sewage suction port is then sucked into the sewage box 33.

[0074] Further, refer to Figures 9 to 12 The host 200 further includes a third connecting valve 35, which includes a first interface and two second interfaces. The first interface is connected to the air extraction port of the first extraction device 34, and the two second interfaces are respectively connected to the clean water box 32 and the sewage box 33. The third connecting valve can selectively connect the first interface to one of the second interfaces.

[0075] Understandably, the second port connected to the water purification box 32 forms the second air extraction branch, and the second port connected to the sewage box 33 forms the first air extraction branch. The third connecting valve 35 can selectively connect the first port to the second port connected to the water purification box 32, or connect the first port to the second port connected to the sewage box 33.

[0076] For example, in a specific implementation, the third communication valve 35 is a three-way solenoid valve. The three-way solenoid valve is controlled by a controller of the host 200 to selectively connect the first interface and one of the second interfaces.

[0077] Reference Figures 9 to 12The base station 100 also includes a cleaning liquid tank 12, a connecting valve 13, and a base station chassis 14 capable of supporting a host 200. The connecting valve 13 includes four interfaces: a first interface connected to a cleaning liquid output pipe 121 of the cleaning liquid tank 12, a second interface connected to a water supply column 19, a third interface connected to a clean water tank 11, and a fourth interface connected to a water outlet of the base station chassis 14. The connecting valve 13 can selectively connect at least two of the four interfaces. The third interface is connected to a clean water tank water supply pipe 111 connected to the clean water tank 11.

[0078] It should be noted that the cleaning liquid and / or clean water sprayed from the water spray port of the base station chassis 14 can clean the wiping parts on the host 200 and also realize self-cleaning of the base station chassis 14 .

[0079] Further, refer to Figures 9 to 12 The base station 100 further includes a second extraction device 15 capable of extracting cleaning liquid from the cleaning liquid tank 12 , and an output port of the second extraction device 15 is connected to the cleaning liquid output pipe 121 .

[0080] It is understandable that the second extraction device 15 can extract the cleaning liquid in the cleaning liquid tank 12 and transport it to the cleaning liquid output pipe 121, and then output it to the outside through the connecting valve 13.

[0081] For example, the second extraction device 15 may be selected from but not limited to a peristaltic pump, a centrifugal pump, a gear pump, a diaphragm pump, and the like.

[0082] Further, refer to Figures 9 to 12 The base station 100 further includes an on-off valve 16, the inlet of which is connected to the second interface of the communication valve 13, and the outlet of which is connected to the water supply 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, and 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 supply column 19.

[0083] It is understandable that the on-off valve 16 can control the conduction or disconnection of its inlet and outlet, so that the inlet and outlet of the on-off valve 16 can be kept in a disconnected state when the water supply column 19 and the water receiving port 321 are disconnected, so as to avoid the situation where the water supply column 19 leaks. When the water supply column 19 and the water receiving port 321 are docked, 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 connecting valve 13 are connected, cleaning liquid can be added to the water purification box 32. If the second interface and the third interface of the connecting valve 13 are connected, clean water can be added to the water purification box 32. If the second interface of the connecting valve 13 is connected to the first interface and the third interface at the same time, clean water and cleaning liquid can be added to the water purification box 32 at the same time.

[0084] For example, the on-off valve 16 may be, but is not limited to, a solenoid valve. The solenoid valve has an inlet and an outlet, and is controlled by the main unit's controller. For example, when the water supply column 19 is docked with the water inlet 321, the main unit's controller 200 controls the inlet and outlet of the solenoid valve to open. When the water supply column 19 and the water inlet 321 are disconnected, the main unit's controller 200 controls the inlet and outlet of the solenoid valve to open and close, preventing leakage from the water supply column 19.

[0085] Further, refer to Figures 9 to 12 The above-mentioned base station 100 also includes a third extraction device 17, the water inlet pipe 171 of the third extraction device 17 is connected to the fourth interface of the connecting valve 13, and the water outlet pipe 172 of the third extraction device 17 is connected to the water outlet on the base station chassis 14.

[0086] It is understandable that the third extraction device 17 can provide power for the cleaning liquid and / or clean water to enter the base station chassis, or the third extraction device 17 can extract the cleaning liquid and / or clean water to the base station chassis 14, so that the cleaning liquid and / or clean water can be sprayed out through the water nozzle to clean the wiping parts on the host 200 or to self-clean the base station chassis 14.

[0087] For example, the third extraction device 17 may be selected from, but not limited to, a water pump, a magnetic pump, a pneumatic diaphragm pump, a centrifugal pump, and the like.

[0088] Further, refer to Figures 9 to 12 The above-mentioned base station 100 also includes a sewage tank 18 and a fourth extraction device 20. The fourth extraction device 20 has an exhaust pipe, which is connected to the sewage tank 18 to vacuum the sewage tank 18 so that the sewage on the base station chassis 14 enters the sewage tank 18.

[0089] It is understood that when the water outlet of the base station chassis 14 sprays cleaning fluid and / or clean water to clean the mopping parts on the main unit 200, or when the base station chassis 14 is self-cleaned and generates sewage, the fourth extraction device 20 can vacuum 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 drawn into the sewage tank 18, thereby collecting the sewage on the base station chassis 14. The sewage tank 18 and the sewage tank on the base station chassis 14 are connected by a pipeline.

[0090] Continue to refer to Figure 12 The base station 100 further includes a second silencer box 21 having a second silencer cavity. The exhaust pipe of the fourth extraction device 20 is connected to the second silencer cavity. The second silencer box 21 has a second exhaust hole connected to the second silencer cavity.

[0091] It is understandable that when the fourth extraction device 20 vacuums the sewage tank 18, the exhausted gas enters the second silencing chamber for silencing, and is then discharged to the outside of the base station 100 through the second exhaust hole, which can avoid generating loud noise when the fourth extraction device 20 is working.

[0092] Exemplarily, the fourth extraction device 20 may be selected from but not limited to an air pump, a centrifugal fan, a vacuum pump, an ion pump, etc., to achieve vacuuming of the sewage tank 18 .

[0093] Further, refer to Figure 12 The main unit 200 further includes a fifth extraction device 36, which is used to extract water from the clean water box 32 of the main unit 200 to wet the mop. Specifically, the water inlet of the fifth extraction device 36 is connected to the clean water box 32 via a pipeline, and the water outlet of the fifth extraction device 36 delivers water through a pipeline to wet the mop, thereby keeping the mop moist while cleaning the floor and improving the cleaning effect.

[0094] For example, the fifth extraction device 36 may be, but is not limited to, a water pump.

[0095] Further, refer to Figure 12 The main unit 200 further includes a first muffler box 37 having a first muffler cavity. The air outlet of the first extraction device 34 is connected to the first muffler cavity. The first muffler box 37 further includes a first exhaust hole connected to the first muffler cavity. The first exhaust hole is located at the top of the wiping member.

[0096] It is understandable that when the first extraction device 34 vacuums the sewage box 33 or the water purification box 32, the exhausted gas enters the first silencer chamber for silencing, and is then discharged to the outside of the host 200 through the first exhaust hole, which can avoid the first extraction device 34 from generating loud noise when working.

[0097] Further, refer to Figure 13 The host 200 includes a body 31 , on which the water purification box 32 , the sewage box 33 and the first extraction device 34 are all mounted, and the water inlet 321 is provided on the side wall of the body 31 .

[0098] In this embodiment, the connecting valve 13 can selectively connect any two of its four interfaces, or can selectively connect any three of its four interfaces in pairs, or can selectively connect any four interfaces in pairs.

[0099] For example, in a specific implementation, referring to Figures 9 to 13 , the four interfaces of the connecting valve 13 are connected in pairs.

[0100] In one case, when water needs to be added to the clean water box 32 of the main unit 200, when the water supply column 19 and the water inlet 321 are connected, the on-off valve 16 makes its inlet and outlet conductive, and the first extraction device 34 vacuums the clean water box 32 through the second air extraction branch. If the second extraction device 15 is not working at this time, the clean water in the clean water tank 11 enters the clean water box 32; if the second extraction device 15 is working 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 enter the clean water box 32.

[0101] In the second case, if only the third extraction device 17 is operating, the clean water in the clean water tank 11 enters the water outlet of the base station chassis 14, which can then clean the mopping and wiping parts of the main unit 200 or perform self-cleaning of the base station chassis 14. If the third extraction device 17 is operating while the second extraction device 15 is also operating, the clean water in the clean water tank 11 and the cleaning liquid in the cleaning liquid tank 12 mix and then enter the water outlet of the base station chassis 14, which can then clean the mopping and wiping parts of the main unit 200 or perform self-cleaning of the base station chassis 14.

[0102] In the third case, the water supply column 19 and the water inlet 321 may be connected, the on-off valve 16 allows the inlet and outlet to be conductive, and the first extraction device 34 and the third extraction device 17 operate simultaneously. If the second extraction device 15 is operating at this time, the first extraction device 34 vacuums the water purification box 32 through the second air extraction branch, and the mixture of clean water and cleaning liquid enters the water purification box 32. The third extraction device 17 extracts the mixture of clean water and cleaning liquid to the water outlet of the base station chassis 14. If the second extraction device 15 is not operating at this time, the first extraction device 34 extracts clean water into the water purification box 32, and the third extraction device 17 extracts clean water to the water outlet of the base station chassis 14.

[0103] The operating states of third extraction device 17 and first extraction device 34 do not affect each other. When first extraction device 34 is operating, third extraction device 17 may or may not operate. Similarly, when third extraction device 17 is operating, first extraction device 34 may or may not operate. Similarly, when third extraction device 17 is operating, the inlet and outlet of on-off valve 16 may be in either the open or closed state.

[0104] It should be noted that when the first extraction device 34 vacuums the water purification box 32 through the second exhaust branch, the second extraction device 15 does not work, that is, only clean water is added to the water purification box 32 of the main unit 200, avoiding adding cleaning liquid into the water purification box 32, thereby avoiding the mopping part from producing watermarks on the ground during the cleaning process.

[0105] Furthermore, when the host 200 is located on the base station chassis 14, if the mopping and wiping member of the host 200 is being cleaned, if the mopping and wiping member is rotating in reverse, both the third extraction device 17 and the second extraction device 15 will operate, cleaning the mopping and wiping member with a mixture of clean water and cleaning fluid. If the mopping and wiping member is rotating in the forward direction, only the third extraction device 17 will operate, cleaning the mopping and wiping member with clean water, thereby purging the cleaning fluid from the mopping and wiping member. The terms "forward" and "reverse" are relative terms, meaning that the mopping and wiping member rotates in opposite directions in each case. The specific rotational directions of the mopping and wiping member during forward and reverse rotation are set based on actual needs.

[0106] It should be noted that the communication valve 13 at this time can be selected as a four-way pipe, which is conducive to reducing costs. Of course, it can also be selected as a solenoid valve.

[0107] For example, in another specific implementation, the communication valve 13 can selectively connect any two interfaces among its four interfaces.

[0108] If the first interface and the second interface are connected, when the water supply column 19 is connected to the water inlet 321, and the inlet and outlet of the on-off valve 16 are connected, the first extraction device 34 vacuums the clean water box 32 through the second air exhaust branch, and the cleaning liquid in the cleaning liquid tank 12 can be added to the clean water box 32 of the main unit 200 through the water supply column 19.

[0109] If the first interface and the third interface are connected, the cleaning liquid in the cleaning liquid tank 12 can be introduced into the clean water tank 11 through the second extraction device 15, so that the cleaning liquid and the clean water tank are mixed.

[0110] If the first interface and the fourth interface are connected, 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 wiping parts of the host 200 or realize self-cleaning of the base station chassis 14.

[0111] If the second interface and the third interface are connected, when the water supply column 19 is connected to the water inlet 321, and the inlet and outlet of the on-off valve 16 are connected, the first extraction device 34 vacuums the water purification box 32 through the second air extraction branch, and the clean water in the clean water tank 11 can be added to the water purification box 32 of the main unit 200 through the water supply column 19.

[0112] If the third interface and the fourth interface are connected, clean water can be delivered to the water outlet of the base station chassis 14 through the third extraction device 17 to clean the wiping parts of the host 200 or realize self-cleaning of the base station chassis 14.

[0113] For example, in another specific implementation, the connecting valve 13 can selectively connect any three interfaces among its four interfaces in pairs.

[0114] If the first, second, and third interfaces are connected in pairs, when the water supply column 19 is connected to the water inlet 321, and the inlet and outlet of the on-off valve 16 are connected, if the first extraction device 34 vacuums the water purification box 32 through the second air extraction branch, the clean water in the clean water tank 11 can be added to the clean water box 32 of the main unit 200 through the water supply column 19. If the second extraction device 15 is working at this time, the cleaning liquid and clean water are mixed and added to the clean water box 32 of the main unit 200 through the water supply column 19.

[0115] If the first interface, the second interface and the fourth interface are connected in pairs, when the water supply column 19 is connected to the water inlet 321, and the inlet and outlet of the on-off valve 16 are connected, the first extraction device 34 vacuums the clean water box 32 through the second air extraction branch, and the second extraction device 15 works at the same time, then the cleaning liquid in the cleaning liquid tank 12 can be added to the clean water box 32 of the main unit 200 through the water supply column 19.

[0116] When the third extraction device 17 and the second extraction device 15 are in operation, cleaning fluid can be delivered to the water outlet of the base station chassis 14 to clean the mopping parts of the host 200 or to achieve self-cleaning of the base station chassis 14. When the third extraction device 17 is in operation, the first extraction device 34 can be in operation or inoperative, and similarly, the inlet and outlet of the on-off valve 16 can be open or closed.

[0117] If the first, third, and fourth interfaces are connected, and if the third extraction device 17 and the second extraction device 15 are operating, a mixture of cleaning fluid and clean water can be delivered to the water outlet of the base station chassis 14 to clean the mopping parts of the host 200 or to achieve self-cleaning of the base station chassis 14. If only the third extraction device is operating, clean water can be delivered to the water outlet of the base station chassis 14 to clean the mopping parts of the host 200 or to achieve self-cleaning of the base station chassis 14.

[0118] If the second, third, and fourth interfaces are connected, when the water supply column 19 is connected to the water inlet 321, and the inlet and outlet of the on-off valve 16 are connected, the first extraction device 34 vacuums the clean water box 32 via the second exhaust branch. Clean water in the clean water tank 11 can then be added to the clean water box 32 of the main unit 200 through the water supply column 19. When the third extraction device is operating, clean water can be delivered to the water outlet of the base station chassis 14 to clean the mopping parts of the main unit 200 or achieve self-cleaning of the base station chassis 14. When the third extraction device 17 is operating, the first extraction device 34 can be operated or not. Similarly, the inlet and outlet of the on-off valve 16 can be connected or disconnected.

[0119] Example 3

[0120] like Figure 14As shown, an embodiment of the present application provides a cleaning system comprising a base station 100 and a main unit 200. The base station 100 comprises a clean water tank 11 and a water supply column 19 connected thereto. The main unit 200 comprises a clean water box 32, a dirty water box 33, and a first extraction device 34. A water inlet 321 is provided on the side wall of the main unit 200, which interfaces with the water supply column 19 and is connected to the clean water box 32.

[0121] The base station 100 also includes a cleaning liquid tank 12 and a first connecting valve 22. The first connecting valve 22 includes three interfaces, wherein the first interface is connected to the cleaning liquid tank 12, the second interface is connected to the clean water tank 11, and the third interface is connected to the water supply column 19. The first connecting valve 22 can selectively connect any at least two of its three interfaces.

[0122] Furthermore, the base station 100 also includes a base station chassis 14 and a second connecting valve 23. The second connecting valve 23 includes three interfaces, wherein the fourth interface is connected to the third interface of the first connecting valve 22, the fifth interface is connected to the water supply column 19, and the sixth interface is connected to the water outlet of the base station chassis 14. The second connecting valve 23 can make any at least two of its three interfaces conductive.

[0123] Further, refer to Figure 14 The base station 100 further includes a second extraction device 15 capable of extracting cleaning liquid from the cleaning liquid tank 12 , and an output port of the second extraction device 15 is connected to the cleaning liquid output pipe 121 .

[0124] It is understandable that the third extraction device 17 can provide power for the cleaning liquid and / or clean water to enter the base station chassis, or the third extraction device 17 can extract the cleaning liquid and / or clean water to the base station chassis 14, so that the cleaning liquid and / or clean water can be sprayed out through the water nozzle to clean the wiping parts on the host 200 or to self-clean the base station chassis 14.

[0125] For example, the third extraction device 17 may be, but is not limited to, a water pump.

[0126] Further, refer to Figure 14 The above-mentioned base station 100 also includes a sewage tank 18 and a fourth extraction device 20. The fourth extraction device 20 has an exhaust pipe, which is connected to the sewage tank 18 to vacuum the sewage tank 18 so that the sewage on the base station chassis 14 enters the sewage tank 18.

[0127] It is understood that when the water outlet of the base station chassis 14 sprays cleaning fluid and / or clean water to clean the mopping parts on the main unit 200, or when the base station chassis 14 is self-cleaned and generates sewage, the fourth extraction device 20 can vacuum 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 drawn into the sewage tank 18, thereby collecting the sewage on the base station chassis 14. The sewage tank 18 and the sewage tank on the base station chassis 14 are connected by a pipeline.

[0128] Continue to refer to Figure 14 The base station 100 further includes a second silencer box 21 having a second silencer cavity. The exhaust pipe of the fourth extraction device 20 is connected to the second silencer cavity. The second silencer box 21 has a second exhaust hole connected to the second silencer cavity.

[0129] It is understandable that when the fourth extraction device 20 vacuums the sewage tank 18, the exhausted gas enters the second silencing chamber for silencing, and is then discharged to the outside of the base station 100 through the second exhaust hole, which can avoid generating loud noise when the fourth extraction device 20 is working.

[0130] Exemplarily, the fourth extraction device 20 may be, but is not limited to, an air pump.

[0131] Further, refer to Figure 14 The main unit 200 further includes a fifth extraction device 36, which is used to extract water from the clean water box 32 of the main unit 200 to wet the mop. Specifically, the water inlet of the fifth extraction device 36 is connected to the clean water box 32 via a pipeline, and the water outlet of the fifth extraction device 36 delivers water through a pipeline to wet the mop, thereby keeping the mop moist while cleaning the floor and improving the cleaning effect.

[0132] For example, the fifth extraction device 36 may be, but is not limited to, a water pump.

[0133] Continue to refer to Figure 14 The host 200 further includes a first muffler box 37 having a first muffler cavity. The exhaust branch of the first extraction device 34 is connected to the first muffler cavity. The first muffler box 37 also has a first exhaust hole connected to the first muffler cavity.

[0134] It is understandable that when the first extraction device 34 vacuums the sewage box 33 or the water purification box 32, the exhausted gas enters the first silencer chamber for silencing, and is then discharged to the outside of the host 200 through the first exhaust hole, which can avoid the first extraction device 34 from generating loud noise when working.

[0135] In this embodiment, the first connecting valve 22 can connect any two of its three interfaces, or connect two of its three interfaces to each other. The second connecting valve 23 can connect any two of its three interfaces, or connect two of its three interfaces to each other.

[0136] For example, in a specific implementation, referring to Figure 14 The three interfaces of the first connecting valve 22 are connected in pairs, and the three interfaces of the second connecting valve 23 are connected in pairs.

[0137] In one scenario, when water needs to be added to the clean water box 32 of the main unit 200, when the water supply column 19 and the water inlet 321 are connected, the on-off valve 16 connects its inlet and outlet, and the first extraction device 34 vacuums the clean water box 32 through the second air extraction branch. If the second extraction device 15 is not working at this time, the clean water in the clean water tank 11 enters the clean water box 32. If the second extraction device 15 is working at this time, the clean water in the clean water tank 11 and the cleaning liquid in the cleaning liquid tank 12 mix and enter the clean water box 32.

[0138] In the second case, if only the third extraction device 17 is also working, the clean water in the clean water tank 11 enters the water outlet of the base station chassis 14, and the wiping parts of the host 200 can be cleaned or the base station chassis 14 can be self-cleaned.

[0139] In the 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 enter the water outlet of the base station chassis 14. At this time, the wiping parts of the host 200 can be cleaned or the base station chassis 14 can be self-cleaned.

[0140] In the fourth case, the water supply column 19 and the water inlet 321 may be connected, the on-off valve 16 allows the inlet and outlet to be conductive, and the first extraction device 34 and the third extraction device 17 operate simultaneously. If the second extraction device 15 is operating at this time, the first extraction device 34 vacuums the water purification box 32 through the second air extraction branch, and the mixture of clean water and cleaning liquid enters the water purification box 32. The third extraction device 17 extracts the mixture of clean water and cleaning liquid to the water outlet of the base station chassis 14. If the second extraction device 15 is not operating at this time, the first extraction device 34 extracts clean water into the water purification box 32, and the third extraction device 17 extracts clean water to the water outlet of the base station chassis 14.

[0141] The operating states of third extraction device 17 and first extraction device 34 do not affect each other. When first extraction device 34 is operating, third extraction device 17 may or may not operate. Similarly, when third extraction device 17 is operating, first extraction device 34 may or may not operate. Similarly, when third extraction device 17 is operating, the inlet and outlet of on-off valve 16 may be in either the open or closed state.

[0142] It should be noted that when the first extraction device 34 vacuums the water purification box 32 through the second exhaust branch, the second extraction device 15 does not work, that is, only clean water is added to the water purification box 32 of the main unit 200, avoiding adding cleaning liquid into the water purification box 32, thereby avoiding the mopping part from producing watermarks on the ground during the cleaning process.

[0143] Furthermore, when the host 200 is located on the base station chassis 14, if the mopping and wiping member of the host 200 is being cleaned, if the mopping and wiping member is rotating in reverse, both the third extraction device 17 and the second extraction device 15 will operate, cleaning the mopping and wiping member with a mixture of clean water and cleaning fluid. If the mopping and wiping member is rotating in the forward direction, only the third extraction device 17 will operate, cleaning the mopping and wiping member with clean water, thereby purging the cleaning fluid from the mopping and wiping member. The terms "forward" and "reverse" are relative terms, meaning that the mopping and wiping member rotates in opposite directions in each case. The specific rotational directions of the mopping and wiping member during forward and reverse rotation are set based on actual needs.

[0144] It should be noted that both the first connecting valve 22 and the second connecting valve 23 can be selected as three-way pipes, which is conducive to reducing costs. Of course, at least one of the first connecting valve 22 and the second connecting valve 23 can also be selected as a solenoid valve.

[0145] For example, in another specific implementation, when the first connecting valve 22 can selectively connect its two interfaces, when the first interface and the third interface are connected, cleaning liquid can be delivered, and when the second interface and the third interface are connected, clean water can be delivered. When the first interface and the second interface are connected, cleaning liquid can be added to the clean water tank 11.

[0146] First, assume that the three interfaces of the second connecting valve 23 are connected in pairs. The second connecting valve 23 can be selected as a three-way pipe to reduce costs. Of course, the second connecting valve 23 can also be selected as a solenoid valve.

[0147] In the first case, the second port and the third port of the first communication valve 22 are connected.

[0148] With the inlet and outlet of the on-off valve 16 open and the water supply column 19 connected to the water inlet 321, if only the first extraction device 34 is operating and the water purification box 32 is evacuated via the second air extraction branch, the clean water in the clean water tank 11 enters the water purification box 32 through the on-off valve 16, the water supply column 19, and the water inlet 321. If the first extraction device 34 is operating and the third extraction device 17 is operating, the clean water in the clean water tank 11 enters the water purification box 32 through the on-off valve 16, the water supply column 19, and the water inlet 321. At the same time, the clean water in the clean water tank 11 is transported to the water outlet of the base station chassis 14 through the third extraction device 17. If only the third extraction device 17 is operating, the clean water in the clean water tank 11 is transported to the water outlet of the base station chassis 14.

[0149] When the inlet and outlet of the on-off valve 16 are disconnected, if the third extraction device 17 is working, the clean water in the clean water tank 11 is transported to the water outlet of the base station chassis 14, which can clean the wiping parts of the host 200 or realize self-cleaning of the base station chassis 14.

[0150] In the second case, the first port and the third port of the first communication valve 22 are connected.

[0151] With the inlet and outlet of the on-off valve 16 open and the water supply column 19 connected to the water inlet 321, if only the first extraction device 34 is operating and the water purification box 32 is vacuumed via the second air extraction branch, the cleaning liquid in the cleaning liquid tank 12 will enter the water purification box 32 through the on-off valve 16, the water supply column 19, and the water inlet 321. If the first extraction device 34 is operating and the third extraction device 17 is operating, the cleaning liquid in the cleaning liquid tank 12 will enter the water purification box 32 through the on-off valve 16, the water supply column 19, and the water inlet 321. At the same time, the cleaning liquid in the cleaning liquid tank 12 is transported to the water outlet of the base station chassis 14 through the third extraction device 17. If only the third extraction device 17 is operating, the cleaning liquid in the cleaning liquid tank 12 is transported to the water outlet of the base station chassis.

[0152] When the inlet and outlet of the on-off valve 16 are disconnected, if the third extraction device 17 is working, the cleaning liquid in the cleaning liquid tank 12 is transported to the water outlet of the base station chassis 14, which can clean the wiping parts of the host 200 or realize self-cleaning of the base station chassis 14.

[0153] Next, assuming that the second connecting valve 23 can selectively connect any two of its interfaces, when the fourth and fifth interfaces are connected, clean water and / or cleaning fluid can be added to the water purification box 32 of the host 200 via the water supply column 19. When the fourth and sixth interfaces are connected, clean water and / or cleaning fluid can be sprayed through the water spray port of the base station chassis 14 to clean the mopping parts of the host 200 or achieve self-cleaning of the base station chassis 14.

[0154] In the first case, the second interface and the third interface of the first connecting valve 22 are connected, and the fourth interface and the sixth interface of the second connecting 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 transported to the water outlet of the base station chassis 14 through the first connecting valve 22 and the second connecting valve 23.

[0155] In the second case, the second interface and the third interface of the first connecting valve 22 are connected, the fourth interface and the fifth interface of the second connecting valve 23 are connected, and when the inlet and outlet of the on-off valve 16 are connected, and the water supply column 19 and the water inlet 321 are connected, the first extraction device 34 can vacuum the water purification box 32 through the second air extraction branch, so that the clean water in the clean water tank 11 enters the water purification box 32 through the first connecting valve 22, the second connecting valve 23, the on-off valve 16, the water supply column 19 and the water inlet 321.

[0156] In the third case, the first interface and the third interface of the first connecting valve 22 are connected, and the fourth interface and the sixth interface of the second connecting valve 23 are connected. At this time, if the third extraction device 17 is working and the second extraction device 15 is working, the cleaning liquid in the cleaning liquid tank 12 is transported to the water outlet of the base station chassis 14 through the first connecting valve 22 and the second connecting valve 23.

[0157] In the fourth case, the first interface and the third interface of the first connecting valve 22 are connected, the fourth interface and the fifth interface of the second connecting valve 23 are connected, and when 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 works, and the first extraction device 34 can vacuum the clean water box 32 through the second air extraction branch, so that the cleaning liquid in the cleaning liquid tank 12 enters the clean water box 32 through the first connecting valve 22, the second connecting valve 23, the on-off valve 16, the water supply column 19 and the water receiving port 321.

[0158] For example, in another specific implementation, if the three interfaces of the first connecting valve 22 are connected in pairs, the second connecting valve 23 can selectively connect any two interfaces thereof.

[0159] In the first case, the fourth interface and the fifth interface are connected. When the inlet and outlet of the on-off valve 16 are connected, and the water supply column 19 is connected to the water receiving port 321, if only the first extraction device 34 is working and the water purification box 32 is vacuumed through the second air extraction branch, the clean water in the clean water tank 11 can enter the clean water box 32 through the first connecting valve 22, the second connecting valve 23, the on-off valve 16, the water supply column 19 and the water receiving port 321. If the first extraction device 34 is working and the water purification box 32 is vacuumed through the second air extraction branch, and the second extraction device 15 is working 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 connecting valve 22 and then enter the clean water box 32 through the second connecting valve 23, the on-off valve 16, the water supply column 19 and the water receiving port 321.

[0160] It should be noted that, preferably, when the first extraction device 34 vacuums the water purification box 32 through the second exhaust branch, the second extraction device 15 does not work, that is, only clean water is added to the water purification box 32 of the main unit 200, and cleaning liquid is avoided from being added to the water purification box 32, thereby avoiding the mopping part from producing watermarks on the ground during the cleaning process.

[0161] In the second scenario, the fourth and sixth interfaces are connected, and the inlet and outlet of on-off valve 16 are either open or closed. If only third extraction device 17 is operating, the clean water in clean water tank 11 is delivered to the water outlet of base station chassis 14 to clean the mopping parts of main unit 200 or to achieve self-cleaning of base station chassis 14. If third extraction device 17 is operating while second extraction device 15 is operating, the clean water in clean water tank 11 and the cleaning liquid in cleaning liquid tank 12 are mixed in first connecting valve 22 and then delivered through second connecting valve 23 to the water outlet of base station chassis 14 to clean the mopping parts of main unit 200 or to achieve self-cleaning of base station chassis 14.

[0162] It should be noted that when the main unit 200 is located on the base station chassis 14, if the mopping and wiping member of the main unit 200 is being cleaned, if the mopping and wiping member is rotated in reverse, both the third extraction device 17 and the second extraction device 15 will operate, cleaning the mopping and wiping member with a mixture of clean water and cleaning fluid. If the mopping and wiping member is rotating in the forward direction, only the third extraction device 17 will operate, cleaning the mopping and wiping member with clean water, thereby purging the cleaning fluid from the mopping and wiping member. The terms "forward" and "reverse" are relative terms, meaning that the rotation direction of the mopping and wiping member is opposite in each case. The specific rotation direction of the mopping and wiping member in forward and reverse rotation is set according to actual needs.

[0163] In this implementation, there is no practical significance when the fifth port and the sixth port of the second communication valve 23 are connected, so it will not be described in detail.

[0164] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.

[0165] The foregoing description is intended only to provide specific embodiments of the present application, which will enable those skilled in the art to understand and implement the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments described herein, but is intended to be construed in the broadest manner consistent with the principles and novel features disclosed herein.
