[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, improving their cleaning effectiveness. Additionally, the cleaning fluid can also flow into the base station's washing tank, further enhancing 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 accurately select different types of cleaning fluid according to cleaning needs and usage environment requirements, which reduces cleaning efficiency and user experience.

The storage compartment can rotate under the drive of a drive component and stop at any position, allowing a drain hole at the bottom of any sub-compartment to connect with the outlet hole of a fluid dispensing component.

[0036] 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.

[0041] 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.

[0042] In related technologies, when a base station's cleaning fluid supply module is equipped with different storage sub-compartments, it is necessary to accurately identify and control the corresponding sub-compartment according to application requirements to release the required cleaning fluid. Currently, cleaning fluid supply modules either have a simple structure that cannot provide multiple cleaning fluids, or their identification and control structures are complex, increasing usage costs.

[0043] Based on this, this application provides a cleaning fluid supply module, including a housing, a storage chamber, a drive assembly, a dispensing assembly, and an angle detection system. The storage chamber is rotatably disposed within the housing and includes multiple partitioned sub-chambers for storing cleaning fluid. Each sub-chamber has a drain hole at its bottom. The drive assembly drives the storage chamber to rotate. The dispensing assembly is at least partially abutted against the bottom of the storage chamber and has a dispensing hole. The angle detection system includes a encoder and a sensor assembly. One of the encoder and the sensor assembly is fixedly connected to the storage chamber, and the other is fixed within the housing. The sensor assembly detects the rotation angle of the encoder to determine the rotation angle of the storage chamber, thereby controlling one of the drain holes to communicate with the dispensing hole.

[0044] The cleaning fluid supply module proposed in this application has a storage compartment with multiple sub-compartments capable of storing different types of cleaning fluid. The storage compartment can rotate under the drive of a drive component and stop at any position, allowing a drain hole at the bottom of any sub-compartment to connect with the outlet hole of the dispensing component. The connected drain hole and outlet hole allow the cleaning fluid in the corresponding sub-compartment to be discharged through the dispensing component. In this way, the cleaning fluid supply module can intelligently and automatically switch 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. Simultaneously, the cleaning fluid supply module has an angle detection system that can detect the rotation angle of the storage compartment. This system identifies the position of the drain hole in each sub-compartment and controls one of the drain holes to connect with the outlet hole of the dispensing component, thereby accurately discharging the liquid from the corresponding sub-compartment.

[0045] The optional embodiments of this application are described in detail below with reference to the accompanying drawings.

[0046] like Figure 1 As shown in the figure, this application embodiment provides a cleaning fluid supply module, which is installed in a base station and is used to automatically provide different types of cleaning fluid according to the needs of cleaning equipment or users.

[0047] This application provides a cleaning fluid supply module including a storage tank 10, a drive assembly 50, a liquid dispensing assembly 20, an angle detection system 30, and a housing 40.

[0048] The storage compartment 10 is rotatably disposed within the housing 40, and includes multiple independent sub-compartments 11 for holding cleaning fluid. Each sub-compartment 11 contains a different cleaning fluid, which can be freely configured according to the cleaning task or environment. The cleaning fluid includes, but is not limited to, floor conditioner, degreaser, disinfectant, deodorizer, and fragrance. Each sub-compartment 11 has a drain hole 111 on its bottom plate 112, which is used to independently drain the cleaning fluid from the corresponding sub-compartment 11.

[0049] The drive assembly 50 has an output end connected to the storage compartment 10, and the drive assembly 50 can drive the storage compartment 10 to rotate within the housing 40 through its output end.

[0050] like Figure 1 , Figure 3 As shown, the liquid outlet assembly 20 is at least partially connected to the bottom of the storage chamber 10, and the liquid outlet assembly 20 has a liquid outlet hole 21. Under the driving action of the drive assembly 50, the storage chamber 10 rotates, and the liquid outlet hole 21 can selectively switch to connect with any one of the leakage holes 111 of each sub-chamber 11, thereby exporting the cleaning fluid in the corresponding sub-chamber 10.

[0051] The angle detection system 30 includes an encoder 31 and a sensor assembly 32. One of the encoder 31 and the sensor assembly 32 is fixedly connected to the storage compartment 10, and the other is fixed inside the housing 40. The sensor assembly 32 is used to detect the rotation angle of the encoder 31 to determine the rotation angle of the storage compartment 10, and then control one of the leakage holes 111 to connect with the liquid outlet hole 21, thereby exporting the cleaning fluid in the corresponding connected sub-compartment 11.

[0052] As can be seen, the cleaning fluid supply module proposed in this application has multiple independent sub-compartments 11 for holding cleaning fluid, and each sub-compartment 11 has an independent drain hole 111. Driven by the drive component 50, the drain holes 111 of each sub-compartment 11 are alternately connected to the outlet hole 21 of the liquid dispensing component 20, thereby enabling the switching of the appropriate type of cleaning fluid according to the user's actual needs or the actual requirements of the environment to be cleaned. Simultaneously, the cleaning fluid supply module has an angle detection system 30 that can detect the rotation angle of the storage compartment 10. The angle detection system 30 can detect and identify the position of the drain hole 111 in each sub-compartment 11, and then control one of the drain holes 111 to connect with the outlet hole 21 of the liquid dispensing component 20, thereby accurately dispensing the liquid from the corresponding sub-compartment 11.

[0053] In one embodiment, a bracket (not shown) is fixedly connected inside the housing 40, and the storage compartment 10 is rotatably connected to the bracket. Thus, the bracket both fixes the storage compartment 10 within the housing 40 and enables its rotatable connection within the housing 40. Exemplarily, the bracket has a rotating opening through which the storage compartment passes. A bearing is provided between the outer wall of the storage compartment and the inner wall of the rotating opening. The outer wall of the bearing is fixedly connected to the inner wall of the rotating opening, and the inner wall of the bearing is fixedly connected to the outer wall of the storage compartment. In this way, the bracket and the bearing achieve both the fixation of the storage compartment 10 within the housing 40 and its rotatable connection within the housing 40. In another example, the storage compartment 10 is mounted on a support. The bottom of the storage compartment 10 has a downwardly extending annular edge. The support has an annular groove for inserting the annular edge. A bearing is provided between the outer wall of the annular edge and the inner wall of the annular groove. The outer wall of the bearing is fixedly connected to the inner wall of the annular groove, and the inner wall of the bearing is fixedly connected to the outer wall of the annular edge. In this way, the support and the bearing realize the fixation of the storage compartment 10 in the housing 40 and the rotational connection of the storage compartment 10 in the housing 40.

[0054] In another embodiment, the liquid dispensing assembly 20 has a rotating shaft, and the bottom of the storage chamber 10 has a rotating hole. The rotating hole is fitted outside the rotating shaft, and a bearing is provided between the outer side wall of the rotating shaft and the inner side wall of the rotating hole. The outer side wall of the bearing is fixedly connected to the inner side wall of the rotating hole, and the inner side wall of the bearing is fixedly connected to the outer side wall of the rotating shaft. In this way, the liquid dispensing assembly 20 and the bearing realize the fixation of the storage chamber 10 in the housing 40 and the rotational connection of the storage chamber 10 in the housing 40.

[0055] In one embodiment, the storage compartment 10 further includes a bottom plate 112, a side plate 113, and a cover plate (not shown in the figure). The side plate 113 encloses a shell structure with an internal cavity and openings at both the bottom and top ends. The bottom plate 112 is fixedly connected to the bottom opening of the side plate 113, 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 113. The bottom plate 112, side plate 113, 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 113 can be any of the following:

[0056] The cover plate is detachably connected to the top opening of the side plate 113. For example, part of the side wall of the cover plate is rotatably connected to the top of the side plate 113, and other parts of the side wall are detachably connected to the top of the side plate 113. For example, the detachable connection method includes, but is not limited to, plug-in, snap-in, 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 113. Then the user can inject liquid into the corresponding sub-compartment 11 as needed.

[0057] The cover plate can also be detachably connected to the top opening of the side plate 113. For example, the cover plate and the top opening of the side plate 113 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 113.

[0058] The cover plate can also be fixedly connected to the top opening of the side plate 113. 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 113. 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.

[0059] To facilitate rotation and to increase the capacity of the storage compartment 10 within the same rotational space, the storage compartment 10 can be configured as a cylindrical structure. Of course, in other embodiments, the storage compartment 10 can also be configured as a square or polygonal shape, and there is no limitation thereto.

[0060] In one embodiment, a plurality of drain holes 111 are arranged along the circumferential direction, and the center of the circle formed by the plurality of drain holes 111 is located on the rotation axis of the storage chamber 10. The projection of the circle formed by the plurality of drain holes 111 in the height direction at least partially overlaps with the liquid outlet 21. In this way, during the rotation of the storage chamber 10, the drain holes 111 can be selectively aligned with any liquid outlet 21 along the circumferential direction, thereby draining the cleaning fluid in the corresponding sub-chamber 11.

[0061] In one embodiment, the storage compartment 10 further includes partitions 114. Multiple partitions 114 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 114 is fixedly connected to the bottom plate 112, one side of each partition 114 parallel to the height direction is fixedly connected to the inner wall of the side plate 113, 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 114 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 114. The preset angles formed by the multiple partitions 114 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 114 form a fan-shaped cavity structure through the preset angles; this cavity structure is the sub-compartment 11.

[0062] 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.

[0063] In one embodiment, the surfaces of the multiple sub-compartments 11 each have different markings, including at least one of the following: color, silkscreen printing, or engraving. By using these different markings, the type of cleaning fluid inside the corresponding sub-compartment 11 can be determined, allowing for the selection of the appropriate type of cleaning fluid to be output or the replenishment of the corresponding cleaning fluid as needed.

[0064] In one embodiment, such as Figure 3 As shown, the drive assembly 50 includes a drive member 51 and a rotating gear 52. The rotating gear 52 is fixedly connected to the storage compartment 10, and the rotation axis of the rotating gear 52 is collinear with the rotation axis of the storage compartment 10. The drive member 51 is fixed inside the housing 40 and is used to drive the rotating gear 52 to rotate.

[0065] For example, the drive unit 51 may include a drive motor 511 and a gear set 512. The drive motor 511 is fixedly mounted inside the housing 40. The gear set 512 may be one or more gears. When the gear set 512 is a single gear, the gear is rotatably connected inside the housing 40 and meshes with the rotating gear 52. In this way, the rotating gear 52 can be driven by a single gear, which has the advantages of simple structure and low cost. When the gear set 512 consists of multiple gears, the multiple gears mesh sequentially and are rotatably connected inside the housing 40. The gears located at the beginning of the multiple gears are coaxially fixed with the output shaft of the drive motor 511, and the gears located at the end of the multiple gears mesh with the rotating gear 52. In this way, the speed ratio of the drive unit 51 can be flexibly adjusted by multiple gears, thereby realizing the adjustment of the speed and torque of the rotating gear 52.

[0066] For example, the rotating gear 52 can be located at the bottom of the storage compartment 10 or sleeved on the outside of the storage compartment 10, as long as the rotation axis of the rotating gear 52 is collinear with the rotation axis of the storage compartment 10. This application does not limit the specific position of the rotating gear 52. The rotation axis of the rotating gear 52 is collinear with the rotation axis of the storage compartment 10, so that the rotating gear 52 can stably drive the storage compartment 10 to rotate.

[0067] In one embodiment, a clearance hole 521 extends along the height direction on the rotating gear 52, and at least a portion of the liquid dispensing assembly 20 is connected to the bottom of the storage compartment 10 through the clearance hole 521. This arrangement allows the clearance hole 521 to accommodate a portion of the liquid dispensing assembly 20, reducing the space occupied by the liquid dispensing assembly 20 in the height 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, thereby improving the adaptability of the base station in a home environment.

[0068] In one embodiment, such as Figure 1 , Figure 3 As shown, the liquid discharge assembly 20 includes a conversion element 22 and a transfer pump 23. The side of the conversion element 22 facing the bottom of the storage chamber 10 is pressed against the bottom of the storage chamber 10. The liquid discharge port 21 penetrates through the conversion element 22, and the liquid inlet 231 of the transfer pump 23 is connected to the liquid discharge port 21. The rotating gear 52 drives the storage chamber 10 to rotate relative to the conversion element 22. When the liquid discharge port 21 of the conversion element 22 is connected to one of the leakage ports 111 at the bottom of the storage chamber 10, the cleaning fluid in the corresponding sub-chamber 11 is discharged through the transfer pump 23. It can be seen that by selectively connecting the liquid discharge port 21 to the leakage port 111, the present application can flexibly realize the discharge of cleaning fluid in any sub-chamber 11.

[0069] In one embodiment, the liquid dispensing assembly 20 further includes a first hose 24, one end of which is connected to a liquid outlet 21, allowing the cleaning fluid in the corresponding sub-compartment 11 to be discharged through a leak hole 111, a liquid outlet 21, and the first hose 24. The end of the first hose 24 furthest from the liquid outlet 21 is connected to an inlet 231, allowing the delivery pump 23 to output the cleaning fluid from the corresponding sub-compartment 11. Optionally, the liquid dispensing assembly 20 also includes a liquid outlet pipe 25, which is connected to the outlet 232 of the delivery pump 23. The delivery pump 23 can discharge the cleaning fluid from the corresponding sub-compartment 11 through the interconnected leak hole 111, liquid outlet 21, and first hose 24, and then guide it to a designated container or space via the liquid outlet pipe 25. Therefore, the liquid dispensing assembly 20 of this application only requires one pump to achieve switching output of different cleaning fluids from multiple sub-compartments 11. Compared to a structure where each sub-compartment 11 is equipped with a separate pump, the liquid dispensing assembly 20 of this application has a simpler structure and lower cost.

[0070] In one embodiment, the code disk 31 has a plurality of detection units distributed in the same number as the leakage holes 111. Each detection unit corresponds one-to-one with a leakage hole 11. The sensor assembly 32 can sense the detection units, thereby determining the correspondence between the leakage holes 111 and the outlet holes 21, and controlling one of the leakage holes 111 to connect with the outlet hole 21. For example, the detection unit can be a reflector, and the sensor assembly 32 can be a reflective photoelectric sensor. The reflective photoelectric sensor has a light source and a receiving unit. Light emitted by the light source is reflected by the reflector and received by the receiving unit, thereby identifying the position of the reflector. Since the reflective intensity and area of ​​the multiple reflectors are different, the reflected light signal from each reflector is different. The reflective photoelectric sensor can determine the specific position of the reflector based on the reflected light signal, and thus determine the position of the leakage hole 11 corresponding to that reflector. In other examples, the detection unit can be a magnet, and the sensor assembly 32 can be a Hall sensor. This embodiment does not specifically limit the type of the detection unit and sensor assembly 32, as long as they can achieve the effect of angle measurement.

[0071] In one embodiment, such as Figure 3As shown, the sensor assembly 32 is an optocoupler, comprising a transmitting element 321 and a receiving element 322, the transmitting element 321 and the receiving element 322 are respectively located on two sides of the code disc 31, specifically, the transmitting element 321 and the receiving element 322 are respectively located on the upper side and the lower side of the code disc 31. The detection part is a through hole 311. When the transmitting element 321, the receiving element 322 and the through hole 311 are located on the same straight line, one of the liquid leakage holes 111 and the liquid outlet hole 21 are in a conductible state. Since one of the code disc 31 and the sensor assembly 32 is fixedly connected to the storage compartment 10, and the other is fixed inside the housing 40, the code disc 31 and the sensor assembly 32 are always in a state of relative rotation. During the relative rotation process of the two, when the transmitting element 321, the receiving element 322 and the through hole 311 are located on the same straight line, the signal (e.g., infrared signal) emitted by the transmitting element 321 can be received by the receiving element 322 through the through hole 311, so that the position of the through hole 311 can be identified, and then the position of the corresponding liquid leakage hole 111 can be identified according to the position of the through hole 311, so as to control the discharge of the cleaning liquid in the corresponding sub-compartment 11.

[0072] In an embodiment, as shown in Figure 2 , the plurality of liquid leakage holes 111 are located on a first circumference with a radius R1, the plurality of detection parts are located on a second circumference with a radius R2, the center of the first circumference and the center O of the second circumference are both located on the central axis of the storage compartment 10, and R1<R2. In this way, by arranging the center of the first circumference and the center of the second circumference to be concentric and both located on the central axis of the storage compartment 10, it is convenient to control the rotation stability of the storage compartment 10 and the code disc, and also convenient to record the positional relationship of the two rotating at the same speed. R1 < R2 enables the second circumference formed by the plurality of detection parts to be located outside the first circumference formed by the plurality of liquid leakage holes 111, so that the sensor assembly 32 can detect the detection parts outside the first circumference, which improves the convenience of detection and reduces the difficulty in structural design.

[0073] Optionally, as shown in Figure 2 , the plurality of liquid leakage holes 111 are evenly distributed on the first circumference, and the plurality of through holes 311 are evenly distributed on the second circumference. Exemplarily, for example, there are 5 liquid leakage holes 111 and 5 through holes 311, the 5 liquid leakage holes 111 are evenly distributed on the first circumference, the 5 through holes 311 are evenly distributed on the second circumference, and the angle between every two adjacent liquid leakage holes 111 and between every two adjacent through holes 311 relative to the center O is 72 degrees respectively. By evenly distributing the liquid leakage holes 111 or the through holes 311, the positional correspondence between the two can be controlled more simply, so that the position of the liquid leakage hole 111 can be calculated simply through the position of the through hole 311.

[0074] Optionally, as shown in Figure 2As shown, the extension of the line connecting the projection of the through hole 311 on the storage compartment bottom plate 112 and the leakage hole 111 passes through the center O of the first circumference. Thus, by setting the extension of the line connecting the projection of the through hole 311 on the storage compartment bottom plate 112 and the leakage hole 111 to pass through the center O of the first circumference, the position of the corresponding leakage hole 111 can be easily obtained directly by detecting the position of the through hole 311.

[0075] In one embodiment, the code disk 31 is fixedly connected to the storage compartment 10, and the sensor assembly 32 is fixed inside the housing 40. Exemplarily, the code disk can be fixedly connected to the bottom of the storage compartment 10 or fixedly sleeved on the outside of the storage compartment 10. In this way, the code disk 31 can rotate synchronously with the storage compartment 10, thereby forming a structure where the code disk 31 rotates relative to the sensor assembly 32. During this relative rotation, the sensor assembly 32 senses the rotation angle of the code disk 31 to determine the rotation angle of the storage compartment 10, and then controls one of the leakage holes 111 to connect with the liquid outlet hole 21.

[0076] In one embodiment, the rotation axis of the code disk 31 is collinear with the rotation axis of the storage compartment 10. When the code disk 31 is fixedly connected to the storage compartment 10, the collinearity of the rotation axis of the code disk 31 and the rotation axis of the storage compartment 10 enables the code disk 31 and the storage compartment 10 to rotate coaxially and synchronously, thereby achieving accurate measurement of the rotation angle of the storage compartment 10.

[0077] In other embodiments, the sensor assembly 32 may be fixedly connected to the storage compartment 10, while the code disk 31 may be fixedly connected to the housing 40. In this way, the sensor assembly 32 can rotate synchronously with the storage compartment 10, thereby forming a structure in which the sensor assembly 32 rotates relative to the code disk 31. During the relative rotation, the sensor assembly 32 senses the rotation angle of the code disk 31.

[0078] 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-compartment 11 according to the material of the surface to be cleaned, the environment, or the weather, so as to select the corresponding cleaning fluid. Alternatively, the user can control the base station to switch the sub-compartment 11 according to personal needs to select the corresponding cleaning fluid.

[0079] This application 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-vacuuming system, and a water replenishment system. When the cleaning device returns to the base station, the vacuuming system, charging system, cleaning system, dirt-vacuuming system, and water replenishment system can work together with the cleaning device to achieve self-cleaning and charging effects. Specifically, the base station's dust extraction system sucks the debris from the cleaning equipment's dustbin into the base station's dust bag, thus cleaning the dustbin. The base station's charging system charges the cleaning equipment's battery to ensure sufficient power for subsequent operations. The cleaning system injects clean water into the base station's cleaning tank to clean the cleaning equipment's cloth (which remains in the cleaning tank when the equipment returns). The base station's wastewater extraction system removes wastewater from the cleaning tank. The base station's water replenishment system replenishes the cleaning equipment's water tank to ensure sufficient clean water for subsequent operations. The cleaning fluid supply module's outlet pipe is connected to the water replenishment system. When the cleaning equipment enters the base station, the base station can intelligently and automatically switch 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 base station to switch sub-compartments 11 according to their needs. The selected cleaning fluid is transported to the base station's water replenishment system via a delivery pump, allowing it to enter the cleaning equipment's water tank. During the cleaning process, the water tank of the cleaning equipment can spray liquid containing cleaning fluid (such as floor conditioner or degreaser) onto the mop to improve its cleaning effect on the surface. Alternatively, 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 of the cleaning fluid supply module can also be connected to the cleaning system, allowing the cleaning fluid (such as degreaser) to be injected into the clean water tank along with the water to clean the cleaning equipment's mop.

[0080] 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.
