Technical Field
[0001] This application relates to the technical field of cleaning systems, specifically to a cleaning fluid supply module, a base station, and a cleaning equipment system. Background Technology
[0002] Base stations equipped with cleaning equipment are typically fitted with a cleaning fluid supply module. This module stores cleaning fluid, which flows into the cleaning equipment's water tank. During subsequent cleaning operations, the tank sprays the fluid-laden liquid onto the cleaning cloths, enhancing their cleaning effectiveness. Additionally, the cleaning fluid can also flow into the base station's washing tank, further improving the cleaning ability of the cleaning equipment's cloths.
[0003] In related technologies, the cleaning fluid supply module can only provide a single type of cleaning fluid and cannot select different types of cleaning fluid according to cleaning needs and usage environment requirements, which reduces cleaning efficiency and user experience.

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0045] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, and other quantifiers are similar.
[0046] It should be understood that although the terms "first," "second," "third," etc., may be used in the embodiments of this application, these descriptions should not be limited to these terms. These terms are only used to distinguish the described objects. For example, "first" may also be referred to as "second," and similarly, "second" may also be referred to as "first," without departing from the scope of the embodiments of this application. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0047] It should be understood that the term "and / or" used in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. The singular forms "a" and "the" are also intended to include the plural forms unless the context clearly indicates otherwise.

[0049] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or device. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or device that includes that element.
[0050] In related technologies, cleaning fluid supply modules can only provide a single type of cleaning fluid, and cannot select different types of cleaning fluid according to cleaning needs and usage environment requirements, thus reducing cleaning efficiency and user experience. Even if some cleaning fluid supply modules can provide multiple cleaning fluids, their driving structure or dispensing structure is either complex, failing to simplify the overall structure of the cleaning fluid supply module and increasing usage costs.
[0051] To address the aforementioned problems, this application provides a cleaning fluid supply module, including a housing, a storage chamber, a dispensing assembly, and a switching assembly. The storage chamber is fixed within the housing and includes multiple partitioned sub-chambers for storing cleaning fluid. Each sub-chamber has a drain hole at its bottom, and each drain hole is connected to a first flexible tube. The dispensing assembly is connected to the end of the multiple first flexible tubes furthest from the storage chamber for delivering the cleaning fluid. The switching assembly includes a valve sleeve and a valve core. The valve sleeve is fitted over the multiple first flexible tubes, and the valve core is rotatably disposed within the valve sleeve and located between the multiple first flexible tubes. The outer periphery of the valve core has a squeezing portion and a clearance notch. When the clearance notch corresponds to one of the first flexible tubes, the squeezing portion can simultaneously squeeze the other first flexible tubes. Specifically, when the squeezing portion squeezes a first flexible tube, the first flexible tube is in a closed state due to pressure; when the clearance notch corresponds to a first flexible tube, the first flexible tube can extend towards the clearance notch to open.
[0052] The cleaning fluid supply module of this application has a storage compartment with multiple sub-compartments capable of storing different types of cleaning fluid. Each sub-compartment has a drain hole at its bottom, and each drain hole is sealed and connected to a first flexible tube. When one of the first flexible tubes is released, the cleaning fluid outlet path of the corresponding compartment is opened. At the same time, the other first flexible tubes are squeezed, closing the cleaning fluid outlet path of the corresponding compartment. In this way, the cleaning fluid supply module can intelligently and automatically switch between sub-compartments based on the material of the surface to be cleaned, the environment, or the weather to select the appropriate cleaning fluid. Alternatively, the user can control the switching of sub-compartments according to their personal needs to select the appropriate cleaning fluid. The selection of multiple cleaning fluids enhances cleaning efficiency and improves the user experience.
[0053] The optional embodiments of this application are described in detail below with reference to the accompanying drawings.
[0054] like Figures 1-2 As shown, this application embodiment provides a cleaning fluid supply module for automatically providing different types of cleaning fluid according to the needs of the application scenario or environment. The cleaning fluid supply module provided in this application embodiment includes a storage tank 10, a dispensing component 20, a switch component 30, and a housing 40.
[0055] Among them, such as Figure 2As shown, the storage compartment 10 is fixed inside the shell 40. The storage compartment 10 includes multiple divided sub-compartments 11, each of which is used to independently store cleaning fluid. The cleaning fluid in each sub-compartment 11 is different and can be freely configured according to the cleaning task or environment. Cleaning fluids include, but are not limited to, floor conditioner, degreaser, disinfectant, deodorizer, and fragrance. Each sub-compartment 11 has a drain hole 111 at its bottom, which is used to independently drain the cleaning fluid from the corresponding sub-compartment 11.
[0056] like Figure 3 As shown, each drain hole 111 is connected to a first hose 113, and there are multiple first hoses 113, each corresponding to one of the drain holes 111. When a first hose 113 is open, the cleaning fluid in the corresponding sub-compartment 11 is discharged from the drain hole 111 along the first hose 113; when a first hose 113 is closed, the cleaning fluid in the corresponding sub-compartment 11 cannot be discharged from the drain hole 111. The first hose 113 can be made of a material with elastic deformation properties, such as rubber. The liquid dispensing assembly 20 is connected to the end of the multiple first hoses 113 away from the storage compartment 10 for conveying the cleaning fluid.
[0057] like Figure 4 As shown, the switch assembly 30 includes a valve sleeve 31 and a valve core 32. The valve sleeve 31 is fitted over a plurality of first hoses 113. The valve core 32 is rotatably disposed inside the valve sleeve 31 and located between the plurality of first hoses 113. The valve core 32 is coaxially arranged with the circumference formed by the plurality of first hoses 113. The outer periphery of the valve core 32 has a compression portion 321 and a clearance notch 322. When the clearance notch 322 corresponds to one of the first hoses 113, the compression portion 321 can simultaneously compress the other first hoses 113. Specifically, when the compression portion 321 compresses the first hose 113, the first hose 113 is in a closed state due to the elastic deformation of the first hose 113. When the clearance notch 322 corresponds to the first hose 113, the first hose 113 can extend towards the clearance notch 322 due to the elastic deformation of the first hose 113, so that the first hose 113 is in a conductive state.
[0058] The cleaning fluid supply module proposed in this application features multiple independently designed sub-compartments 11 for holding cleaning fluid, each with an independent drain hole. Each drain hole 111 is sealed and connected to a first flexible tube 113. A switch assembly 30 releases one first flexible tube 113 while simultaneously closing the others, thus allowing the corresponding sub-compartment 11 to be switched on and off in turn. In this way, the cleaning fluid supply module can intelligently and automatically switch between sub-compartments 11 based on the material of the surface to be cleaned, the environment, or the weather, to select the appropriate cleaning fluid. Alternatively, the user can control the switching of sub-compartments 11 according to their individual needs to select the appropriate cleaning fluid. The availability of multiple selectable cleaning fluids enhances cleaning efficiency and improves the user experience.
[0059] In one embodiment, a bracket (not shown in the figure) is fixedly connected inside the housing 40, and the storage compartment 10 is fixedly connected to the bracket. Exemplarily, the bracket has an mounting opening through which the storage compartment passes, and the outer wall of the storage compartment and the inner wall of the mounting opening are fixedly connected. Alternatively, the outer wall of the storage compartment 10 can be directly fixedly connected to the inner wall of the housing 40. The aforementioned fixed connection methods include, but are not limited to, welding, integral molding, and bonding, etc., achieving the fixed connection of the storage compartment 10 within the housing 40 through the bracket or the inner wall of the housing 40.
[0060] In one embodiment, the storage compartment 10 further includes a bottom plate 112, a side plate 116, and a cover plate (not shown in the figure). The side plate 116 encloses a shell structure with an internal cavity and openings at both the bottom and top. The bottom plate 112 is fixedly connected to the bottom opening of the side plate 116, and the fixing method includes, but is not limited to, welding, integral molding, bolting, etc. The cover plate is connected to the top opening of the side plate. The bottom plate 112, side plate 116, and cover plate together enclose the closed cavity inside the storage compartment 10. The connection method between the cover plate and the top opening of the side plate 116 can be any of the following:
[0061] The cover plate is detachably connected to the top opening of the side plate 116. For example, part of the side wall of the cover plate is rotatably connected to the top of the side plate 116, and other parts of the side wall are detachably connected to the top of the side plate 116. For example, the detachable connection method includes, but is not limited to, plug-in, snap-fit, bolt connection, magnetic attraction, etc. When it is necessary to inject liquid into each sub-compartment 11, the user only needs to remove the detachable part of the cover plate, and then rotate the cover plate to open the opening at the top of the side plate 116. Then the user can inject liquid into the corresponding sub-compartment 11 as needed.
[0062] The cover plate can also be detachably connected to the top opening of the side plate 116. For example, the cover plate and the top opening of the side plate 116 are connected by means of plugging, snapping, bolting, magnetic attraction, etc. When liquid needs to be injected into each sub-chamber 11, the user only needs to remove the cover plate from the top opening of the side plate 116.
[0063] The cover plate can also be fixedly connected to the top opening of the side plate 116. The fixed connection method includes, but is not limited to, welding, integral molding, bolt connection, etc. In this case, the cover plate cannot be removed from the side plate 116. At this time, multiple liquid injection ports can be set on the cover plate. The multiple liquid injection ports correspond one-to-one with multiple sub-chambers 11 and are connected one-to-one. Each liquid injection port is provided with an openable and closable sealing cover. When it is necessary to inject liquid into each sub-chamber 11, the user only needs to open the corresponding sealing cover to inject liquid into the corresponding sub-chamber 11 as needed.
[0064] In one embodiment, the storage compartment 10 further includes partitions 117. Multiple partitions 117 are provided within the storage compartment 10, and are distributed in a radiating pattern within the inner cavity of the storage compartment 10. Specifically, the bottom of each partition 117 is fixedly connected to a base plate, one side of each partition 117 parallel to the height direction is fixedly connected to the inner wall of a side plate 116, and the other side parallel to the height direction extends towards the rotation axis of the storage compartment 10. The sides of the multiple partitions 117 extending towards the rotation axis of the storage compartment 10 are fixedly connected to each other. It should be noted that the above-mentioned fixed connection methods include, but are not limited to, welding, integral molding, and bonding. There is a preset angle between two adjacent partitions 117. The preset angles formed by the multiple partitions 117 can be equal or unequal. During the manufacturing and design phase, the workers can determine the angles according to the volume requirements. Two adjacent partitions 117 form a fan-shaped cavity structure through the preset angles; this cavity structure is the sub-compartment 11.
[0065] It should be noted that this application does not specify the number of sub-compartments 11. The number of sub-compartments 11 can be determined by the staff according to the type and quantity of cleaning fluid.
[0066] In one embodiment, each sub-compartment 11 has a different marking on its surface, including at least one of the following: color, silkscreen printing, or engraving. The type of cleaning fluid inside the corresponding sub-compartment 11 can be determined by these different markings, allowing for the selection of the appropriate type of cleaning fluid to be output or the replenishment of the corresponding cleaning fluid as needed.
[0067] In one embodiment, such as Figure 5As shown, the liquid outlet assembly 20 includes a transition chamber 21 and a delivery pump 22. The transition chamber 21 is fixed inside the housing 40. The interior of the transition chamber 21 has an inner cavity for storing cleaning fluid. One end of a plurality of first hoses 113 away from the storage chamber 10 is connected to the inner cavity. The inlet of the delivery pump 22 and the transition chamber 21 are connected by a pipe. Exemplarily, the transition chamber 21 includes an inner cavity, an inlet end 211, and an outlet end 212. The inlet ends 211 are located on the top surface of the transition chamber 21 and are provided in a plurality of them along the circumference. The plurality of inlet ends 211 correspond one-to-one with and are connected to the plurality of first hoses 113. The outlet end 212 is located on the side of the transition chamber 21 and has one and is connected to a second hose 114. One end of the second hose 114 away from the transition chamber 21 is connected to the inlet 221 of the delivery pump 22. The cleaning fluid in the sub-compartment 11 enters the inner cavity of the transition chamber 21 through the drain hole 111 and the first hose 113, and is then discharged through the outlet end 212, the second hose 114, and the transfer pump 22. The transition chamber 21 is a transfer chamber that can temporarily store the cleaning fluid in one of the sub-compartments 11, and then discharge it through the second hose 114 and the transfer pump 22. The outlet of the transfer pump 22 is connected to the outlet pipe 27, through which the cleaning fluid in the corresponding sub-compartment 11 can be discharged to the cleaning fluid supply module. It can be seen that the discharge assembly of this application only requires one transfer pump 22 to realize the switching output of different cleaning fluids in multiple sub-compartments 11. Compared with the structure of configuring a transfer pump 22 for each sub-compartment 11, the discharge assembly 20 of this application has a simpler structure and lower cost.
[0068] In one embodiment, such as Figure 6 As shown, the valve sleeve 31 has an annular structure, and the valve core 32 is coaxially disposed within the valve sleeve 31. The valve sleeve 31 is fixedly installed within the housing 40. The fixing method of the valve sleeve 31 within the housing 40 can refer to the fixing connection method of the storage compartment 10 within the housing 40, which will not be elaborated further in this application. Multiple positioning notches 311 are provided on the inner wall of the valve sleeve 31. The diameter of the positioning notches 311 is slightly larger than the diameter of the first hose 113. Each positioning notch 311 corresponds one-to-one with a different first hose 113, and at least a portion of the first hose 113 is accommodated within the positioning notch 311. The positioning notches 311 are used to position the first hose 113. Thus, when the first hose 113 is subjected to compression and friction from the valve core 32, the positioning of the first hose 113 through the positioning notches 311 reduces the possibility of positional displacement of the first hose 113.
[0069] In one embodiment, the switch assembly 30 further includes a flexible mating member 33, which is located between a plurality of first hoses 113 and sleeved outside the valve core 32. The pressing portion 321 presses the sidewall of the flexible mating member 33 to compress the first hoses 113, thereby placing the first hoses 113 in a closed state; the first hoses 113 and the flexible mating member 33 can extend toward the clearance notch 322 to place the first hoses 113 in a conductive state.
[0070] Specifically, when the clearance notch 322 rotates to a position opposite to one of the first hoses 113, the flexible mating member 33 also retracts towards the clearance notch 322. Since there is a large space between the clearance notch 322 on the outer wall of the valve core 32 and the first hose 113, it will not compress the first hose 113, thus releasing the first hose 113 and making it conductive. Simultaneously, the compression part 321 compresses the flexible mating member 33, which in turn compresses the other first hoses 113, causing them to close due to pressure.
[0071] With this configuration, the flexible mating part 33 can protect the first hose 113 between the first hose 113 and the valve core 32, reducing the possibility of damage to the first hose 113 caused by the valve core 32 directly squeezing and rubbing against it.
[0072] In one embodiment, the inner wall of the flexible mating member 33 has multiple compression protrusions 331, each corresponding to a plurality of first hoses 113. The compression protrusions 331 extend from the inner wall of the flexible mating member 33 towards its center. When the compression part 321 compresses the compression protrusion 331, the outer wall of the flexible mating member 33 compresses the first hoses 113, causing them to be in a closed state. When the clearance notch 322 is directly opposite the compression protrusion 331, the compression protrusion 331 enters the clearance notch 322, causing the first hoses 113 to be in a conductive state. This arrangement reduces the design considerations for the distance between the valve core 32 and the valve sleeve 31. By adding compression protrusions 331 to the flexible mating member 33, the distance between the valve core 32 and the valve sleeve 31 can be adjusted, thereby effectively compressing and releasing the first hoses 113.
[0073] In one embodiment, such as Figure 7 As shown, the switch assembly 30 also includes a drive member 34, which has an output end. An output shaft 341 is coaxially fixed to the output end, and the output shaft 341 is coaxially fixed to the valve core 32. Thus, during operation, the drive member 34 can drive the output shaft 341 to rotate, and the rotation of the output shaft 341 can drive the valve core 32 to rotate synchronously. During the rotation of the valve core 32, the opening and closing of multiple first hoses 113 is realized.
[0074] For example, the drive unit 34 may include a drive motor 342, which is fixedly installed inside the housing 40. The drive shaft of the drive motor 342 is coaxially fixedly connected to the output shaft 341. The drive motor 342 can directly drive the output shaft 341 to rotate, thereby driving the valve core 32 to rotate. In another example, the drive unit 34 may include a drive motor 342 and a gear set 343. The drive motor 342 is fixedly installed inside the housing 40. The gear set 343 may include multiple gears that mesh sequentially and are rotatably connected inside the housing 40. The gear at the beginning of the gear set is coaxially fixed to the drive shaft of the drive motor 342, and the gear at the end of the gear set is coaxially fixed to the output shaft 341. In this way, the speed ratio of the drive unit 34 can be flexibly adjusted through the multiple gears, thereby achieving the adjustment of the speed and torque of the valve core 32. For example, gear set 343 includes a first gear 3431 and a second gear 3432. The first gear 3431 is coaxially fixed with the drive shaft of the drive motor 342, and the second gear 3432 is coaxially fixed with the output shaft 341. The first gear 3431 and the second gear 3432 mesh with each other. The drive motor 342 drives the first gear 3431 to rotate, the first gear 3431 drives the second gear 3432 to rotate, and the second gear 3432 drives the output shaft 341 to rotate, thereby driving the valve core 32 to rotate.
[0075] In one embodiment, the transition chamber 21 has a ring-shaped structure, with a hollow region 213 running vertically through its middle area. The hollow region 213 provides clearance for the installation of the switch assembly 30. After passing through the hollow region 213, the output shaft 341 is coaxially fixed with the valve core 32. This arrangement allows the hollow region 213 to accommodate part of the output shaft 341, reducing the space occupied by the output shaft 341 in the vertical direction, thereby reducing the overall height of the cleaning fluid supply module. After the cleaning fluid supply module is installed in the base station of the cleaning equipment, the overall height of the base station can be reduced, thus improving the adaptability of the base station in a home environment.
[0076] In one embodiment, the transition chamber 21, the output shaft 341, and the valve core 32 are coaxially arranged. This improves the coaxiality of the transition chamber 21, the output shaft 341, and the valve core 32, reduces the diameter of the hollow region 213, thereby reducing the size of the transition chamber 21 in the diametrical direction and thus reducing the overall width of the cleaning fluid supply module.
[0077] In one embodiment, a rotary bearing is fixed between the outer wall of the output shaft 341 and the inner wall of the hollow region 213 of the transition chamber 21. With this arrangement, the rotary bearing improves the rotational stability of the output shaft 341 and the valve core 32, enabling the output shaft 341 to stably drive the valve core 32 through the rotary bearing while the transition chamber 21 remains stationary.
[0078] In one embodiment, such as Figure 8 As shown, the cleaning fluid supply module also includes a detection component 50, which is located at the bottom of the storage compartment 10. The detection component 50 includes a encoder 51 and an optocoupler 52. The encoder 51 is coaxial and fixedly connected to the valve core 32. This arrangement allows the encoder 51 and the valve core 32 to rotate synchronously, improving synchronization and reducing rotation errors. The detection end of the optocoupler 52 is located at the edge of the encoder 51 and is used to detect the rotation angle of the encoder 51, thereby determining the rotation angle of the valve core 32. In this way, through the cooperation of the encoder 51 and the optocoupler 52, the rotation angle of the valve core 32 can be measured. Based on the rotation angle, the cleaning fluid supply module can control the drive component 34 to rotate the valve core 32 to a specified angle so that the clearance notch 322 corresponds to the specified first hose 113, thereby accurately controlling which sub-compartment 11 from which the cleaning fluid is discharged.
[0079] For example, the code disk 51 has a plurality of through holes 511, the same number as the leakage holes 111. A connecting bracket (not shown in the figure) is fixedly connected to the shaft of the output shaft 341 located between the transition chamber 21 and the gear set 343. The connecting bracket is fixedly connected to the code disk 51 on the outer side away from the output shaft 341. In this way, the coaxial fixation between the code disk 51 and the output shaft 341 can be achieved through the connecting bracket, thereby achieving coaxial rotation between the code disk 51 and the valve core 32. The optocoupler 52 is fixedly installed in the housing 40. The optocoupler 52 includes a transmitting element and a receiving element, which are located on the upper and lower sides of the code disk 51, respectively. With this setup, during the rotation of the valve core 32, the output shaft 341 drives the encoder 51 to rotate synchronously. When the transmitting element, the receiving element, and the through hole 511 are on the same straight line, the receiving element can receive the signal from the transmitting element, thereby determining the position of the through hole 511. Then, based on the position of the through hole 511, the position of the clearance notch 322 can be determined. The cleaning fluid supply module can control the corresponding first hose 113 to be connected based on the position of the clearance notch 322.
[0080] As described in the above embodiment, the cleaning fluid supply module is provided with multiple independent sub-chambers 11 for containing cleaning fluid. Each sub-chamber 11 has a drain hole 111 at its bottom. Each drain hole 111 is sealed and connected to a first hose 113. The opening and closing of the first hose 113 can be controlled by rotating the switch assembly 30. When the first hose 113 is released, the cleaning fluid outlet path of the corresponding sub-chamber 11 is opened. At the same time, when other first hoses 113 are squeezed, the cleaning fluid outlet path of the corresponding other sub-chamber 11 is closed, thereby realizing the application requirements of switching different cleaning fluids as needed.
[0081] This application embodiment also provides a base station, including the cleaning fluid supply module as described in any of the above embodiments. After the base station is equipped with the cleaning fluid supply module, the base station can intelligently and automatically switch the sub-chamber 11 by controlling the rotation of the valve core 32 according to the material of the surface to be cleaned, the environment, or the weather, so as to select the cleaning fluid with the corresponding function. Alternatively, the user can control the base station to switch the sub-chamber 11 by controlling the rotation of the valve core 32 according to personal needs, so as to select the cleaning fluid with the corresponding function.
[0082] This application embodiment also provides a cleaning system, including a base station and a cleaning device. The base station includes a cleaning fluid supply module as described in any of the above embodiments. The cleaning device can be a robotic vacuum cleaner, capable of autonomously entering and leaving the base station. The base station has a vacuuming system, a charging system, a cleaning system, a dirt-collecting system, and a water replenishment system. When the cleaning device returns to the base station, the vacuuming system, charging system, cleaning system, dirt-collecting system, and water replenishment system work together with the cleaning device to achieve self-cleaning and charging effects. Specifically, the base station's vacuuming system is used to suck the debris from the cleaning device's dustbin into the base station's dust bag to clean the debris in the cleaning device's dustbin; the base station's charging system is used to charge the cleaning device's battery to ensure that the cleaning device has sufficient energy for subsequent work; the cleaning system is used to inject clean water into the base station's cleaning tank to clean the cleaning device's cloth (when the cleaning device returns to the base station, the cleaning device's cloth is located in the base station's cleaning tank); the base station's dirt-collecting system is used to remove wastewater from the cleaning tank; and the base station's water replenishment system is used to replenish the water tank in the cleaning device to ensure that the cleaning device has sufficient clean water for subsequent work. The outlet pipe 27 of the cleaning fluid supply module is connected to the water replenishment system. When the cleaning equipment enters the base station, the base station can intelligently and automatically switch the sub-chamber 11 by controlling the rotation of the control valve core 32, based on the material of the surface to be cleaned, the environment, or the weather, to select the corresponding cleaning fluid. Alternatively, the user can control the base station to switch the sub-chamber 11 by controlling the rotation of the control valve core 32, based on their personal needs, to select the corresponding cleaning fluid. The selected cleaning fluid is transported to the water replenishment system of the base station via the delivery pump 22, so that the corresponding cleaning fluid enters the water tank of the cleaning equipment. During the cleaning process, the water tank can spray liquid containing cleaning fluid (such as floor maintenance liquid, degreasing cleaning liquid, etc.) onto the mop to improve the cleaning effect of the mop on the surface to be cleaned, or the water tank can spray liquid containing cleaning fluid (such as fragrance liquid) onto the ground to meet the user's environmental needs. The outlet pipe 27 of the cleaning fluid supply module can also be connected to the cleaning system, so that the cleaning fluid (such as degreasing cleaning fluid) can be injected into the clean water tank along with the injected clean water to clean the rag of the cleaning equipment.
[0083] It should be noted that the dust collection system, charging system, cleaning system, dirt suction system and water replenishment system of the above-mentioned base station are all existing conventional technologies, and this application will not elaborate on them further.
