[0007] A floor scrubber is typically equipped with a base station. When the user needs to clean a specific area, they remove the scrubber from the base station and use it to clean the area.

[0062] The technical solutions of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present application, not all embodiments. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other unless there is a conflict.

[0063] It should be noted that the terms "first", "second", etc. in the description and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0064] In this application, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit this application.

[0065] As shown in Figures 1 to 4, the present application provides a cleaning device for cleaning a target location, such as a home environment, a shopping mall, an office building, etc. In one exemplary scenario, the cleaning device is a floor scrubber for cleaning the floor. Of course, the cleaning device includes but is not limited to floor scrubbers, and may also be a vacuum cleaner, a sweeper, etc.

[0066] The following description will mainly use the cleaning device 1000 as a floor scrubber as the main scenario, but based on the above description, it can be seen that the protection scope of the embodiments of the present application is not limited thereby.

[0067] Cleaning device 1000 comprises a body, which includes a floor brush assembly 101 and a housing 102 connected to floor brush assembly 101. The bottom of housing 102 is pivotally connected to floor brush 101, and a handle 103 is provided on the top of housing 102 for the user to hold. Handle 103 is provided with control keys for controlling the operating state of cleaning device 1000. These control keys include an on / off button, a cleaning mode button, and a self-cleaning button. These keys can be independent or multiple keys can be a single key.

[0068] A suction source 100 is housed within the body 102. This source is used to generate negative pressure and serves as the power source for the cleaning device 1000. A fresh water tank 104 and a waste collection container 200 are detachably mounted on the body 102. These are located at the front and rear of the body 102, with the side facing away from the user considered the front and the side facing closer to the user considered the rear. The outer walls of the fresh water tank 104 and waste collection container 200 can be considered part of the outer walls of the body 102, resulting in a compact and aesthetically pleasing structure.

[0069] The dirt collection container 200 is used to collect dirt sucked in during the cleaning process. The clean water tank 104 is used to store cleaning liquid. During the floor scrubber cleaning process, the cleaning liquid in the clean water tank 104 is used to wet the roller brush of the floor brush assembly 101 (not shown). The cleaning liquid can be clean water or a mixture of clean water and cleaning liquid, fragrance, fungicide, etc.

[0070] As shown in Figure 4, the interior of the machine body 102 includes an internal sewage suction duct 110 formed between the suction source 100 and the sewage collection container 200. The suction source 100 is located above the internal sewage suction duct 110. The suction airflow generated by the suction source 100 during operation creates a negative pressure within the sewage collection container 200, drawing external dirt on the floor to be cleaned, as well as external dirt generated during self-cleaning, into the sewage collection container 200 through the floor brush assembly 101. After being filtered, the suction airflow continues through the internal sewage suction duct 110 to the suction source 100, and then flows out through the air outlet of the suction source 100.

[0071] Furthermore, an external sewage suction duct 120 is formed inside the body 102 , and the internal sewage suction duct 110 and the external sewage suction duct 120 are independent of each other. The above “independent of each other” means that the internal sewage suction duct 110 and the external sewage suction duct 120 are not connected.

[0072] Among them, the outer wall of the fuselage 102 is also provided with a body docking port 105. One end of the external sewage suction duct 120 is connected to the suction source 100, and the other end is connected to the body docking port 105. In other words, the external sewage suction duct 120 can connect the suction source 100 and the body docking port 105. When the suction source 100 is working, a negative pressure can be formed at the body docking port 105, thereby achieving the purpose of providing suction force to the external device. The above-mentioned "external device" can be a base station 400, or it can be other equipment that requires suction force. The following is an example of the external device being a base station 400.

[0073] In one embodiment, as shown in Figure 18 , base station 400 includes a main unit 410, a dirt storage container 420, and a base station fresh water tank 430. The dirt storage container 420 is connected to a sewage pipe. The main unit 410 is located at the center of the base station 400 to facilitate docking with the floor scrubber. The dirt storage container 420 and the base station fresh water tank 430 are located on opposite sides of the main unit 410. This structure effectively utilizes space.

[0074] The base station 400 also includes a tray 440 provided at the lower part of the host 410. A cleaning cavity is formed on the top of the tray 440. When the floor scrubber is docked with the base station 400, the roller brush of the floor brush assembly 101 of the floor scrubber is located in the cleaning cavity, thereby enabling operations such as cleaning or drying to be performed on the roller brush.

[0075] The liquid in the base station clean water tank 430 can be used to clean the roller brush or replenish the clean water tank 104 of the floor scrubber. The main unit 410 can also be provided with a shelf (not shown) on which a cleaning brush can be placed. The user can use the brush to clean the dirt storage container 420 and the base station clean water tank 430, providing convenient cleaning for the user.

[0076] In another embodiment, as shown in Figure 19, the base station 400 includes a main unit 410 and a waste container 420, with the waste container 420 being mounted on the main unit 410. In this embodiment, the base station 400 does not include a base station fresh water tank 430. The main unit 410 is connected to an external water source via a water inlet pipe (not shown). When the scrubber's fresh water tank 104 requires refilling, the base station 400 refills the tank 104 via the water inlet pipe. This "external water source" can be municipal water or other sources.

[0077] In another embodiment, the base station 400 is provided with a sewage pipe (not shown) and a water inlet pipe (not shown), but is not provided with the sewage storage container 420 and the base station clean water tank 430 .

[0078] When the base station 400 is equipped with a waste storage container 420, the external waste suction duct 120 is used to enable the suction source 100 to provide suction force to the waste storage container 420, thereby sucking the waste in the waste collection container 200 of the floor scrubber into the waste storage container 420 of the base station 400. When the base station 400 is not equipped with a waste storage container 420, the external waste suction duct 120 is used to enable the suction source 100 to provide negative pressure to the waste discharge pipe, thereby sucking the waste in the waste collection container 200 of the floor scrubber into the waste discharge pipe of the base station 400.

[0079] When the floor scrubber is docked with the base station 400, a sewage extraction channel (not shown) is formed between the sewage collecting container 200 on the floor scrubber and the sewage storage container 420 or the sewage discharge pipe on the base station 400. Under the action of the negative pressure provided by the suction source 100, the base station 400 can suck the sewage in the sewage collecting container 200 into the base station 400.

[0080] In one embodiment, the suction source 100 can be connected to the internal sewage suction duct 110 and the external sewage suction duct 120 at the same time, that is, the external dirt can be sucked into the sewage collecting container 200 at the same time, and the dirt in the sewage collecting container 200 can be sucked into the base station 400 to empty the sewage collecting container 200 of the floor scrubber, avoiding the user from manually dumping the dirt, thereby improving the user's experience.

[0081] However, if both the internal and external sewage suction ducts 110, 120 are connected to the suction source 100, the external sewage suction duct 120 will occupy some of the suction force of the suction source 100 while the scrubber itself is performing its suction task, thereby affecting the cleaning efficiency and effectiveness of the scrubber. This is undesirable. In this embodiment, the cleaning device 1000 also includes an air path switching structure 300, which is used to connect the suction source 100 to either the internal or external sewage suction duct 110, 120. In other words, at any given moment, only one of the internal or external sewage suction duct 110, 120, is connected to the suction source 100.

[0082] Specifically, when the scrubber itself is performing a waste suction task, the internal waste suction duct 110 is connected to the suction source 100. At this point, the suction force provided by the suction source 100 is fully used to suck waste, allowing external waste to be smoothly drawn into the waste collection container 200, thereby enhancing the scrubber's cleaning performance. When the scrubber is docked with a base station, if the base station is required to perform a waste suction task, the suction force provided by the suction source 100 is fully utilized by the base station, providing it with a greater negative pressure suction force. This eliminates the need for a separate negative pressure generator on the base station, greatly simplifying its structure.

[0083] As shown in Figure 4, the air path switching structure 300 is arranged between the suction source 100 and the internal sewage suction air duct 110 and the external sewage suction air duct 120, wherein the end of the internal sewage suction air duct 110 close to the suction source 100 is connected to the suction source 100 through the air path switching structure 300, and the end of the external sewage suction air duct 120 close to the suction source 100 is also connected to the suction source 100 through the air path switching structure 300.

[0084] As shown in Figures 5 to 13, the air path switching structure 300 includes a housing 310 and a switching member 320 movably disposed within the housing 310. The housing 310 is provided with a first air port 311 connected to the internal sewage suction duct 110, a second air port 312 connected to the external sewage suction duct 120, and a third air port 313 connected to the suction source 100. The first air port 311, the second air port 312, and the third air port 313 are respectively connected to the inner cavity of the housing 310, which houses the switching member 320.

[0085] The suction source 100 has an air inlet (not shown), and the third air outlet 313 is always connected to the air inlet of the suction source 100. Under the action of an external force, the switching member 320 changes its relative position with the housing 310, so that the third air outlet 313 is connected to either the first air outlet 311 or the second air outlet 312. This allows the suction source 100 to be connected to either the internal sewage suction duct 110 or the external sewage suction duct 120. In other words, a single suction source 100 can generate negative pressure in the internal sewage suction duct 110 and the sewage collection container 200, as well as in the external sewage suction duct 120 and the base station connected thereto.

[0086] The switching member 320 can rotate automatically or manually. When the switching member 320 rotates automatically, the air duct switching structure 300 further includes a drive assembly 360, which is disposed outside the housing 310. The drive assembly 360 includes an output shaft, which is in transmission connection with the switching member 320 and is used to drive the switching member 320 to move. It is worth noting that the movement of the switching member 320 can be rotational or linear reciprocating. Preferably, the switching member 320 is rotated within the housing 310 under the drive of the drive assembly 360.

[0087] Specifically, the switching member 320 has a rotation axis X. The output shaft of the drive assembly 360 can be colinear or parallel to the rotation axis X of the switching member 320, or can be perpendicular to it. This can be achieved by providing a reduction unit between the output shaft and the switching member 320. The drive assembly 360 can be a motor, a rotary cylinder, etc. When the switching member 320 is manually rotated, the rotation axis of the switching member 320 can be extended to the outside of the fuselage 102. The user can manually rotate the switching member 320 to connect the suction source 100 to either the internal suction duct 110 or the external suction duct 120.

[0088] The housing base 310 is separately provided along the rotation axis X of the switching member 320 , or the housing base 310 is separately provided along the radial direction of the switching member 320 , thereby facilitating the installation of the switching member 320 in the housing base 310 .

[0089] Furthermore, the air duct switching structure 300 further includes a rotation limiting unit 340 . The rotation limiting unit 340 is provided between the switching member 320 and the housing base 310 . The rotation limiting unit 340 is used to limit the rotation position of the switching member 320 .

[0090] Specifically, the switching member 320 has a first position when the first air port 311 is connected to the third air port 313 and the second air port 312 is isolated from the third air port 313, and a second position when the first air port 311 is isolated from the third air port 313 and the second air port 312 is connected to the third air port 313. The rotation limiting unit 340 is used to limit the first and second positions of the switching member 320, thereby automatically switching the switching member 320 between the first and second positions. The rotation limiting unit 340 includes a position sensor that detects the position of the switching member 320. The position sensor can be a Hall switch, a limit switch, or the like.

[0091] When the base station 400 needs to perform sewage extraction, the driving component 360 drives the switching member 320 to rotate along the first working direction by a first preset angle so that the switching member 320 is located in the second position. At this time, the external sewage suction duct 120 is connected to the suction source 100, and the suction source 100 is not connected to the base station 400. When the suction source 100 is working, the gas in the base station 400 enters the shell seat 310 through the external sewage suction duct 120, and then enters the suction source 100 after passing through the shell seat 310, thereby forming a negative pressure in the base station 400.

[0092] When the floor scrubber performs the sewage suction operation, the driving component 360 drives the switching member 320 to rotate in the opposite direction, and the switching member 320 rotates along the second working direction by a second preset angle so that the switching member 320 is located in the first position. At this time, the internal sewage suction air duct 110 is connected to the suction source 100, and the external sewage suction air duct 120 is not connected to the suction source 100. When the suction source 100 is working, the gas in the sewage collecting container 200 enters the shell seat 310 through the internal sewage suction air duct 110, and then enters the suction source 100 after passing through the shell seat 310, thereby forming a negative pressure in the sewage collecting container 200.

[0093] The first working direction and the second working direction may be opposite. For example, if the first working direction is clockwise, the second working direction is counterclockwise; and if the first working direction is counterclockwise, the second working direction is clockwise. Of course, the first working direction and the second working direction may also be the same. For example, if the first working direction is clockwise, the second working direction is also clockwise; and if the first working direction is counterclockwise, the second working direction is also counterclockwise.

[0094] The first preset angle and the second preset angle may be the same or different. Preferably, the first preset angle and the second preset angle are the same and may be set to an obtuse angle, for example, any angle such as 100° or 105°, or an acute angle, for example, 72° or 80°, or 90°.

[0095] Furthermore, a planar bearing 350 is disposed between at least one end of the switching member 320 and the inner wall of the housing 310. The provision of the planar bearing 350 enables the switching member 320 to rotate stably and reliably within the inner cavity of the housing 310. A bearing mounting structure (not shown) is disposed on one of the end of the switching member 320 and the inner wall of the housing 310. The planar bearing 350 is mounted on the housing 310 or the switching member 320 via the bearing mounting structure.

[0096] In this embodiment, the air path switching structure has the following structures:

[0097] In the first case, the switching member 320 in the shell base 310 is a baffle, as shown in Figure 13, the first air outlet 311 and the second air outlet 312 are adjacent and distributed side by side, and the first air outlet 311 and the second air outlet 312 are respectively located on opposite sides of the switching member 320, and the switching member 320 has a first state when it rotates along the first direction to close the first air outlet 311, and a second state when it rotates along the second direction to close the second air outlet 312, wherein the first direction is opposite to the second direction, for example, when the first direction is counterclockwise, the second direction is clockwise, and similarly, when the first direction is clockwise, the second direction is counterclockwise.

[0098] In the second case, as shown in Figures 5 to 11, the switching member 320 in the shell base 310 is hollow cylindrical, and the switching member 320 has a blocking portion and a switching channel. The blocking portion is used to close the first air port 311 or the second air port 312, and the switching channel is used to connect the first air port 311 with the third air port 313, or to connect the second air port 312 with the third air port 313, so as to realize the connection between the suction source 100 and either the internal sewage suction duct 110 or the external sewage suction duct 120.

[0099] The first air outlet 311, the second air outlet 312 and the third air outlet 313 are located in the circumferential direction of the shell base 310, and the first air outlet 311, the second air outlet 312 and the third air outlet 313 are respectively distributed at intervals along the circumference of the shell base 310, wherein the first air outlet 311 and the second air outlet 312 are staggered along the rotation axis X direction of the switching member 320.

[0100] The blocking portion is a portion of the circumferential outer wall of the switching member 320. The switching channel includes the hollow cavity of the switching member 320, and a first opening 3211 and a second opening 3221 formed on the circumferential wall of the switching member 320. The first opening 3211 and the second opening 3221 are respectively connected to the hollow cavity of the switching member 320. It can be understood that the switching channel runs through the switching member 320.

[0101] The first opening 3211 cooperates with the first air outlet 311, the second opening 3221 cooperates with the second air outlet 312, and the third air outlet 313 is always connected to the switching channel. When the first air outlet 311 is closed by the blocking portion, the switching channel connects the second air outlet 312 and the third air outlet 313; when the second air outlet 312 is closed by the blocking portion, the switching channel connects the first air outlet 311 and the third air outlet 313.

[0102] The switching member 320 is arranged in a separate body along the rotation axis X. It includes a first switching portion 321 and a second switching portion 322. The first switching portion 321 and the second switching portion 322 are pluggable and mating. Specifically, the plug-in end of one of the first switching portion 321 and the second switching portion 322 is provided with a protrusion 323 extending along the rotation axis X of the switching member 320, while the plug-in end of the other switching portion is provided with a groove 324 that mates with the protrusion 323. The engagement between the protrusion 323 and the groove 324 enables circumferential position limiting. When one of the first switching portion 321 and the second switching portion 322 rotates, the other rotates synchronously. Specifically, as shown in Figures 8 and 9, the first switching portion 321 is connected to the drive assembly 360. When the drive assembly 360 drives the first switching portion 321 to rotate, the second switching portion 322 rotates synchronously. The axial position of the first and second switching portions 321 and 322 is limited by the inner cavity of the housing 310.

[0103] Specifically, the first opening 3211 is located on the circumferential wall surface of the first switching part 321, the second opening 3221 is located on the circumferential wall surface of the second switching part 322, and the blocking part includes a first blocking part 3212 located on the first switching part 321 and a second blocking part 3222 located on the second switching part 322. The first blocking part 3212 can cooperate with the first air outlet 311, and the second blocking part 3222 can cooperate with the second air outlet 312.

[0104] To improve the sealing performance of the first and second sealing portions 3212 and 3222, in this embodiment, the first and second sealing portions 3212 and 3222 are recessed radially inwardly along the switching member 320 to form mounting grooves 325. Sealing members 330 are fixedly disposed within the mounting grooves 325. The sealing members 330 are used to improve the sealing performance of the first and second sealing portions 3212 and 3222. The sealing members 330 may be rubber pads, silicone pads, or the like.

[0105] In the third embodiment, as shown in Figures 14 to 17 , the switching member 320a is in a fan-shaped block shape. The spacing between the first air outlet 311a, the second air outlet 312a, and the third air outlet 313a on the housing 310a in the direction of the rotation axis Xa of the switching member 320a is zero. In other words, the first air outlet 311a, the second air outlet 312a, and the third air outlet 313a are not staggered in the direction of the rotation axis Xa. This structure makes the air path switching structure 300 compact in the direction of the rotation axis Xa.

[0106] The first air outlet 311a and the second air outlet 312a are located on the same circumferential surface centered on the rotation axis Xa, and the third air outlet 313a is located approximately on an extension of the same straight line as either the first air outlet 311a or the second air outlet 312a. Preferably, the third air outlet 313a is located approximately on an extension of the same straight line as the first air outlet 311a to minimize the presence of bends and thereby reduce wind resistance.

[0107] The switching member 320a comprises a blocking portion 321a that engages with the first and second air ports 311a, 312a, and a through-hole 322a extending along the switching member's rotational direction. The blocking portion 321 forms the outer circumference of the switching member 320a and is used to close the first and second air ports 311, 312. The blocking portion 321a is also provided with a sealing sheet 323a, which is attached to the outer surface of the blocking portion 321a. The sealing sheet 323a can be made of an elastic material such as rubber or sponge.

[0108] The through-hole 322a can be considered the switching channel of the switching member 320. The switching channel is used to connect the first air port 311a with the third air port 313a, or to connect the second air port 312a with the third air port 313a. When the first air port 311a is closed by the blocking portion 321a, the through-hole 322a connects the second air port 312a with the third air port 313a. When the second air port 312a is closed by the blocking portion, the through-hole 322a connects the first air port 311a with the third air port 313a, thereby connecting the suction source 100 with either the internal sewage suction duct 110 or the external sewage suction duct 120.

[0109] In this embodiment, as shown in Figure 2, the body docking port 105 is located close to the suction source 100, minimizing the length of the external suction duct 120 and thereby reducing wind damage. A downwardly facing receiving groove 106 is recessed into the outer shell of the body 102, and the body docking port 105 is received within this groove. This prevents the body docking port 105 from being directly exposed to the outer shell of the body 102, resulting in an aesthetically pleasing appearance and an enhanced user experience.

[0110] Furthermore, the suction source 100 also has a protective cover (not shown), and the suction source 100 is accommodated in the protective cover. The protective cover of the suction source 100 can be integrally formed with the housing 310 of the air path switching structure 300, or can be separated from each other.

[0111] The housing 102 is also provided with a refill port (not shown) for replenishing the clean water tank 104 and a drain port (not shown) for discharging waste from the waste collection container 200. The docking port 105 and at least one of the refill port and drain port are located on the same side of the housing 102 to facilitate docking with the base station and simplify the docking structure between the scrubber and the base station. The "same side" refers to surfaces facing the same direction.

[0112] A container cleaning unit (not shown) is installed within the waste collection container 200 and is located on top of the container 200. This unit includes at least one cleaning nozzle (not shown) that sprays the inner wall of the waste collection container 200 to remove any dirt adhering to the inner wall, keeping the container 200 relatively clean. Specifically, the cleaning nozzle of the container cleaning unit is in fluid communication with the clean water tank 104 via a first drive pump unit (not shown). The clean water tank 104 supplies liquid to the container cleaning unit to ensure the proper cleaning process.

[0113] In some application scenarios, the body 102 is not only equipped with the clean water tank 104 and the dirt collection container 200, but also with a liquid agent box (not shown) for storing functional liquid. In this case, the clean water tank 104 is used to store clean water, and the clean water in the clean water tank 104 is transported to the roller brush through a pipeline (not shown). The liquid agent box is connected to the above pipeline via a peristaltic pump. The functional liquid in the liquid agent box can be mixed with the clean water through the pipeline and then transported to the roller brush together.

[0114] Example 2

[0115] As shown in Figures 1, 18, 19 and 20, the present application also provides a cleaning system, which includes a base station 400, a cleaning device 1000 and a control device (not shown). Among them, the cleaning device 1000 is the cleaning device described in Example 1. The floor scrubber (cleaning device 1000) can be docked at the base station 400, so that the base station 400 can maintain the floor scrubber, for example, clean the dirty liquid in the floor scrubber, replenish the floor scrubber with cleaning liquid (such as water, water / detergent mixture, etc.), charge the floor scrubber, etc., so as to facilitate the subsequent use of the floor scrubber. The control device includes a processor, which can be set independently of the floor scrubber and the base station, or can be set in the floor scrubber and / or the base station. In other words, the control device can be a controller in the floor scrubber or the base station, or a controller that cooperates with the floor scrubber and the base station, or a terminal independent of the floor scrubber and the base station. The terminal can be, but is not limited to, a mobile phone, a tablet computer, a portable wearable device, etc.

[0116] In one embodiment, as shown in FIG18 , a base station 400 includes a main unit 410, a waste container 420, and a base station clean water tank 430. The waste container 420 is connected to a sewage pipe (not shown). The sewage pipe can be provided based on actual conditions. For example, when the waste container 420 is fixed to the main unit 410, it is preferably connected to the sewage pipe. When the waste container 420 is detachably attached to the main unit 410, the sewage pipe may or may not be provided.

[0117] The host 410 is located at the center of the base station 400 to facilitate docking with the floor scrubber. The dirt storage container 420 and the base station clean water tank 430 are respectively arranged on opposite sides of the host 410. This structure can effectively utilize space.

[0118] The base station 400 also includes a tray 440 provided at the lower part of the host 410. A cleaning cavity is formed on the top of the tray 440. When the floor scrubber is docked with the base station 400, the roller brush of the floor brush assembly 101 of the floor scrubber is located in the cleaning cavity, thereby enabling operations such as cleaning or drying to be performed on the roller brush.

[0119] The liquid in the base station clean water tank 430 can be used to clean the floor scrubber or to replenish the clean water tank 104 of the floor scrubber. A shelf (not shown) can also be provided on the main unit 410 to hold a cleaning brush. The user can use the brush to clean the dirt storage container 420 and the base station clean water tank 430, providing convenient cleaning for the user.

[0120] As shown in Figure 21, the base station 400's housing is equipped with a base station sewage outlet 460, a base station suction outlet 450, and a water inlet (not shown). The base station sewage outlet 460 and the base station suction outlet 450 are each connected to the sewage storage container 420. Specifically, the main unit 410 has a sewage air duct and a sewage channel. The sewage air duct is used to allow air to flow through, and the sewage channel is used to allow sewage to pass through. The base station suction outlet 450 is connected to the suction source 100 through the sewage air duct. The connection between the sewage air duct and the suction source 100 may also be equipped with a filter structure. The base station sewage outlet 460 is connected to the sewage storage container 420 through the sewage channel. The water inlet is connected to the base station clean water tank 430. After the scrubber is connected to the base station 400, the machine body sewage outlet is sealed with the base station sewage outlet 460, the machine body docking port 105 is sealed with the base station suction outlet 450, and the liquid inlet of the clean water tank 104 is sealed with the water inlet.

[0121] When the body docking port 105 is sealed and docked with the base station suction port 450, the suction source 100 can establish fluid communication with the base station 400 via the external sewage suction duct 120. Fluid communication between the suction source 100 and the base station 400 can refer to fluid communication between the suction source 100 and the sewage storage container 420. Thus, the negative pressure of the suction source 100 can generate a negative pressure in the sewage storage container 420, thereby sucking the sewage in the sewage collection container 200 into the sewage storage container 420, and then automatically discharging the sewage from the sewage storage container 420 to the outside, or allowing the user to manually empty the sewage storage container 420.

[0122] The suction source 100 and the base station 400 are fluidically connected, which may also refer to the suction source 100 and the sewage pipe of the base station 400 (not shown in the figure) forming a fluid connection. In this way, the suction source 100 can generate negative pressure in the sewage pipe of the base station 400, thereby sucking the dirt in the sewage collecting container 200 into the sewage pipe of the base station 400 and discharging it to the outside through the sewage pipe.

[0123] When the control device detects that the base station 400 needs to pump out the sewage from the sewage collection container 200 (for example, the sewage collection container 200 is full, a sewage pumping instruction is received, etc.), the driving component 360 can be controlled to drive the switching component 320 to rotate, so that the suction source 100 is connected to the external sewage suction duct 120. At this time, the suction source 100 and the base station 400 form a fluid connection. The suction force generated by the suction source 100 sucks the gas in the base station 400, causing the sewage storage container 420 or the sewage discharge pipe of the base station 400 to generate negative pressure. Under the action of the negative pressure, the dirt in the sewage collection container 200 is sucked into the base station 400, thereby achieving the goal of automatically recovering the sewage in the sewage collection container 200 of the floor scrubber to the base station 400 without setting a negative pressure device at the base station 400, thereby reducing the number of negative pressure devices, thereby simplifying the overall structure of the cleaning system, facilitating installation and maintenance, and reducing the production cost of the cleaning system.

[0124] In yet another embodiment, as shown in Figures 19 and 20, the base station 400 includes a host 410 and a dirt storage container 420, and the dirt storage container 420 is provided on the host 410. In this solution, the base station 400 is not provided with a base station clean water tank 430, and the host 410 is connected to an external water source through a water inlet pipe (not shown). When the clean water tank 104 of the floor scrubber needs to be replenished with water, the base station 400 replenishes the clean water tank 104 of the floor scrubber through the water inlet pipe. The above-mentioned "external water source" can be municipal water or other forms of water sources. At this time, the external sewage air duct 120 provides suction force to the dirt storage container 420 to suck the dirt in the dirt collection container 200 of the floor scrubber into the dirt storage container 420 of the base station 400.

[0125] In another embodiment, the base station 400 is provided with a sewage discharge pipe (not shown) and a water inlet pipe (not shown), but does not include the sewage storage container 420 and the base station clean water tank 430. The external sewage suction duct 120 is used to enable the suction source 100 to provide negative pressure to the sewage discharge pipe, thereby sucking the sewage in the sewage collection container 200 of the floor scrubber into the sewage discharge pipe of the base station 400.

[0126] Obviously, the embodiments described above are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, ordinary technicians in this field can make other different forms of changes or modifications without making any creative work, which should fall within the scope of protection of this application.
