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 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0047] 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.

[0048] 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.

[0049] To address the aforementioned problems, this application provides a cleaning fluid supply module, including a housing, a storage chamber, and a drive assembly. 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. A dispensing assembly is at least partially abutted against the bottom of the storage chamber and has a dispensing hole. Under the drive of the drive assembly, the dispensing hole can selectively communicate with any one of the drain holes, allowing the dispensing assembly to discharge the cleaning fluid from the corresponding sub-chamber.

[0050] The cleaning fluid supply module of 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 an outlet hole of the outlet component. The connected drain hole and outlet hole allow the cleaning fluid in the corresponding sub-compartment to be discharged through the outlet 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.

[0051] The optional embodiments of this application are described in detail below with reference to the accompanying drawings.

[0052] like Figures 1-3 As shown in the figure, this application embodiment provides a cleaning fluid supply module, which is used to automatically provide different types of cleaning fluid according to the needs of the application scenario or application environment. The cleaning fluid supply module provided in this application embodiment includes a storage tank 10, a drive assembly 20, a liquid dispensing assembly 30, and a housing 40.

[0053] The storage compartment 10 is rotatably disposed within the housing 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. 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 at its bottom for independently draining the cleaning fluid from the corresponding sub-compartment 11.

[0054] The drive assembly 20 is connected to the bottom of the storage compartment 10. For example, at least a portion of the drive assembly 20 is fixedly connected to the bottom of the storage compartment 10 by bolts, and the drive assembly 20 drives the storage compartment 10 to rotate.

[0055] The liquid outlet assembly 30 is at least partially connected to the bottom of the storage chamber 10, and the liquid outlet assembly 30 has a liquid outlet hole 311. Under the driving action of the drive assembly 20, the storage chamber 10 rotates, and the liquid outlet hole 311 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.

[0056] As can be seen, the cleaning fluid supply module proposed in this application sets up multiple independent sub-chambers 11 for containing cleaning fluid, and each sub-chamber 11 is provided with an independent leakage hole 111. The leakage hole 111 of each sub-chamber 11 is turned on to connect with the liquid outlet hole 311 of the liquid outlet component 30 by the drive component 20, so that the corresponding type of cleaning fluid can be switched to be exported according to the actual needs of the user or the actual needs of the environment to be cleaned.

[0057] 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.

[0058] In another embodiment, the liquid dispensing assembly 30 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 30 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.

[0059] 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. The bottom plate 112, the side plate 113, and the 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:

[0060] 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. 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-chamber 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. Then the user can inject liquid into the corresponding sub-chamber 11 as needed.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] In one embodiment, a plurality of drain holes 111 are arranged circumferentially, 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 outlet hole 311. In this way, during the rotation of the storage chamber 10, the drain holes 111 can be selectively aligned with any outlet hole 311 in the circumferential direction, thereby discharging the cleaning fluid in the corresponding sub-chamber.

[0065] 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.

[0066] 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.

[0067] Optionally, each sub-compartment 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.

[0068] In one embodiment, such as Figure 4 As shown, the drive assembly 20 includes a drive member 21 and a rotating gear 22. The rotating gear 22 is fixedly connected to the storage compartment 10, and the rotation axis of the rotating gear 22 is collinear with the rotation axis of the storage compartment 10. The drive member 21 is fixed inside the housing 40 and is used to drive the rotating gear 22 to rotate.

[0069] For example, the drive unit 21 may include a drive motor 211 and a gear set 212. The drive motor 211 is fixedly mounted inside the housing 40. The gear set 212 may be one or more gears. When the gear set 212 is a single gear, the gear is rotatably connected inside the housing 40 and meshes with the rotating gear 22. In this way, the rotating gear 22 can be driven by a single gear, which has the advantages of simple structure and low cost. When the gear set 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 211, and the gears located at the end of the multiple gears mesh with the rotating gear 22. In this way, the speed ratio of the drive unit 21 can be flexibly adjusted by multiple gears, thereby realizing the adjustment of the speed and torque of the rotating gear 22.

[0070] For example, the rotating gear 22 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 22 is collinear with the rotation axis of the storage compartment 10. This application does not limit the specific position of the rotating gear 22. The rotation axis of the rotating gear 22 is collinear with the rotation axis of the storage compartment 10, so that the rotating gear 22 can stably drive the storage compartment 10 to rotate.

[0071] In one embodiment, a clearance hole 221 extends along the height direction on the rotating gear 22, and at least a portion of the liquid dispensing assembly 30 is connected to the bottom of the storage compartment 10 through the clearance hole 221. This arrangement allows the clearance hole 221 to accommodate a portion of the liquid dispensing assembly 30, reducing the space occupied by the liquid dispensing assembly 30 in the height direction, thereby reducing the overall height of the cleaning fluid supply module. After the cleaning fluid supply module is installed on 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.

[0072] In one embodiment, the liquid dispensing assembly 30 further includes a sealing ring 34, which is disposed between the outer side wall of the conversion member 31 and the inner side wall of the clearance hole 221. With this arrangement, if leakage occurs between the liquid dispensing assembly 30 and the bottom of the storage chamber 10, the sealing ring 34 can play a protective role to prevent the cleaning fluid in the storage chamber 10 from leaking out from the gap between the conversion member 31 and the rotating gear 22.

[0073] In one embodiment, such as Figures 4-6As shown, the liquid discharge assembly 30 includes a conversion element 31 and a transfer pump 32. The side of the conversion element 31 facing the bottom of the storage chamber 10 is pressed against the bottom of the storage chamber 10. The liquid discharge port 311 penetrates through the conversion element 31. The liquid inlet 321 of the transfer pump 32 is connected to the liquid discharge port 311. The rotating gear 22 drives the storage chamber 10 to rotate relative to the conversion element 31. When the liquid discharge port 311 of the conversion element 31 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 32. It can be seen that by selectively connecting the liquid discharge port 311 to the leakage port 111, the present application can flexibly realize the discharge of cleaning fluid in any sub-chamber 11.

[0074] In one embodiment, the conversion component 31 includes a mounting base 312 and a sealing member 313. The mounting base 312 has a first receiving cavity 3121 on the side facing the bottom of the storage compartment 10. The sealing member 313 is disposed in the first receiving cavity 3121, and the side of the sealing member 313 facing the bottom of the storage compartment 10 is not lower than the end of the first receiving cavity 3121 facing the bottom of the storage compartment 10, so that the sealing member 313 abuts against the bottom of the storage compartment 10, thereby sealing the conversion component 31 against the bottom of the storage compartment 10 and preventing the cleaning fluid from leaking out from the gap between the top surface of the conversion component 31 and the bottom of the storage compartment 10. In this embodiment, the liquid outlet 311 penetrates the sealing member 313 and the mounting base 312. When the liquid outlet 311 of the conversion component 31 is connected to one of the leakage holes 111 at the bottom of the storage compartment 10, the cleaning fluid in the corresponding sub-compartment 11 can be discharged through the liquid outlet 311. Optionally, the side of the seal 313 facing the bottom of the storage compartment 10 is higher than the end of the first receiving cavity 3121 facing the bottom of the storage compartment 10. For example, the height of the seal 313 above the first receiving cavity 3121 is 1mm-3mm, thereby allowing the seal 313 to abut more tightly against the bottom of the storage compartment 10, further sealing the bottom of the conversion member 31 and the storage compartment 10. The seal 313 is at least partially elastic. For example, the surface of the seal 313 is made of flexible rubber, allowing the flexible rubber surface of the seal 313 to elastically contact the bottom of the storage compartment 10 when the seal 313 abuts against the bottom of the storage compartment 10, thereby improving the sealing performance between the seal 313 and the bottom of the storage compartment 10. In other examples, the middle portion of the seal 313 in the height direction is made of flexible rubber, thus making the seal 313 elastic.

[0075] In one embodiment, the first receiving cavity 3121 of the conversion member 31 has a positioning member 3122 at its center, and correspondingly, the sealing member 313 has a positioning hole 3131 at its center. The positioning hole 3131 is fitted onto the positioning member 3122 to achieve positioning of the sealing member 313. Optionally, the positioning hole 3131 and the positioning member 3122 have the same shape, such as square, polygonal, or circular. To prevent the sealing member 313 from sliding along the first receiving cavity 3121 due to rotation, thereby causing misalignment of the liquid outlet 311, the positioning hole 3131 is preferably a non-circular positioning hole. Optionally, the sealing member 313 and the bottom surface of the first receiving cavity 3121 are provided with other structures for positioning the sealing member 313, such as a concave-convex structure or an adhesive structure, to further prevent misalignment of the liquid outlet 311. The sealing member 313 can be made of elastic materials such as rubber, and there is no limitation on this.

[0076] Optionally, the conversion component 31 includes an intermediate partition 3124, a first receiving cavity 3121 located on the upper side of the intermediate partition 3124, and a second receiving cavity 3123 located on the lower side of the intermediate partition 3124. The liquid outlet 311 passes through the intermediate partition 311 and connects the first receiving cavity 3121 and the second receiving cavity 3123. The liquid outlet 311 extends into the second receiving cavity 3123 and is provided with a connector 3125 for connecting to the first hose 33.

[0077] In one embodiment, the liquid dispensing assembly 30 further includes a first hose 33, one end of which is connected to a liquid outlet 311, allowing the cleaning fluid in the corresponding sub-compartment 11 to be discharged through the leak hole 111, the liquid outlet 311, and the first hose 33. The end of the first hose 33 furthest from the liquid outlet 311 is connected to an inlet 321, allowing the delivery pump 32 to output the cleaning fluid from the corresponding sub-compartment 11. Optionally, the liquid dispensing assembly 30 also includes a liquid outlet pipe 38, which is connected to the outlet of the delivery pump 32. The delivery pump 32 can discharge the cleaning fluid from the corresponding sub-compartment 11 through the interconnected leak hole 111, the liquid outlet 311, and the first hose 33, and guide it to a designated container or space via the liquid outlet pipe 38. Therefore, the liquid dispensing assembly 30 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 of this application has a simpler structure and lower cost.

[0078] In one embodiment, such as Figure 6 and Figure 7 As shown, the liquid dispensing assembly 30 also includes a support member 36 and an elastic member 35. The support member 36 is fixed inside the housing 40, and the conversion member 31 can slide along the height direction on the support member 36. The elastic member 35 is disposed between the conversion member 31 and the inner wall of the housing 40. The elastic force of the elastic member 35 can press the side of the conversion member 31 facing the bottom of the storage compartment 10 against the bottom of the storage compartment 10.

[0079] For example, the support member 36 is a columnar structure extending upward from the bottom of the housing 40 along the height direction. The fixing method between the support member 36 and the bottom of the housing 40 can be a fixed connection such as welding, bonding, or integral molding, or a detachable connection such as snap-fit, plug-in, or threaded connection. This application does not limit this, as long as the support member 36 can be stably fixed inside the housing 40. The number of support members 36 is not less than two. Multiple support members 36 cooperate with the conversion member 31, which improves the stability of the conversion member 31 during the sliding process. The conversion member 31 is provided with a lug 317 corresponding to the position of the support member 36. The lug 317 has a through hole 3171, which passes through and slides with the support member 36. In this way, the sliding cooperation between the through hole 3171 and the support member 36 defines the sliding direction of the conversion member 31, thereby realizing the stable sliding of the conversion member 31 in the height direction.

[0080] The elastic element 35 can be a compression coil spring, a spring sheet, etc. The elastic element 35 is disposed between the conversion element 31 and the inner wall of the housing 40; specifically, it is disposed between the bottom of the conversion element 31 and the bottom of the housing 40. The elastic force of the elastic element 35 allows the conversion element 31 to move upwards, so that the conversion element 31 abuts against the bottom of the storage compartment 10, thereby achieving a sealed connection between the conversion element 31 and the bottom of the storage compartment 10. This reduces the possibility of cleaning fluid leaking out from the gap between the conversion element 31 and the bottom of the sub-compartment 11 during the process of cleaning fluid flowing into the outlet hole 311 through the leakage hole 111, thus improving the sealing performance.

[0081] In one embodiment, a portion of the elastic member 35 is located within the second receiving cavity 3123, while another portion extends out of the second receiving cavity 3123 and abuts against the inner wall of the housing 40, such as the bottom surface of the housing 40. With this arrangement, the second receiving cavity 3123 can accommodate a portion of the elastic member 35, reducing the space occupied by the elastic member 35 in the height direction, thereby reducing the overall height of the cleaning fluid supply module.

[0082] In one embodiment, the elastic member 35 is always in a compressed state, so that the elastic force of the elastic member 35 can always press the side of the conversion member 31 facing the bottom of the storage compartment 10 against the bottom of the storage compartment 10. With this configuration, the elastic member 35, which is always in a compressed state, can always move the conversion member 31 upward, so that the conversion member 31 can always be pressed against the bottom of the storage compartment 10, thereby further improving the sealing performance between the conversion member 31 and the bottom of the storage compartment 10.

[0083] In one embodiment, a limiting member 361 is fixed on the support member 36, and the conversion member 31 passes through the support member 36 and the limiting member 361 at least partially. The end of the limiting member 361 away from the support member 36 is provided with a limiting portion 362, which is located on the side of the conversion member 31 away from the support member 36, and is used to limit the highest position of the conversion member 31 sliding along the height direction.

[0084] Specifically, the lug 317 of the conversion part 31 passes through the support part 36 and the limiting part 361. The fixing method between the limiting part 361 and the support part 36 includes, but is not limited to, threaded connection, plug-in, snap-fit, adhesive, welding, integral molding, etc., as long as the limiting part 361 can be fixed on the support part 36. This application does not limit this. The connection method between the limiting part 362 and the end of the limiting part 361 away from the support part 36 includes, but is not limited to, threaded connection, plug-in, snap-fit, adhesive, welding, integral molding, etc., as long as the limiting part 362 can be fixed on the end of the limiting part 361 away from the support part 36. This application does not limit this. The limiting part 362 is located on the side of the lug 317 away from the support member 36, and the maximum length of the limiting part 362 in the horizontal direction is greater than the diameter of the through hole 3171. In this way, the through hole 3171 cannot pass through the limiting part 362, thereby limiting the maximum sliding distance of the conversion member 31 in the height direction and preventing the conversion member 31 from falling off the support member 36.

[0085] It should be noted that the rotation angle of the aforementioned storage compartment 10 can be achieved by controlling the drive motor 211. For example, the drive motor 211 can be a stepper motor, which has the advantages of high precision and strong controllability. The cleaning fluid supply module can control the rotation angle of the storage compartment 10 by controlling the rotation angle of the stepper motor. The control logic of the stepper motor is existing technology and will not be described in detail here. The rotation angle of the aforementioned storage compartment 10 can also be achieved by setting another sensor. The types of sensors include, but are not limited to, photoelectric speed sensors, magnetoelectric speed sensors, Hall effect speed sensors, etc. Detecting the rotation angle using sensors is existing technology and will not be described in detail here. In this way, by controlling the rotation angle of the storage compartment 10, the alignment accuracy of the liquid outlet 311 and the corresponding leakage hole 111 can be improved.

[0086] This application embodiment also provides a base station, including a cleaning fluid supply module as described in any of the above embodiments. After the base station is equipped with a 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.

[0087] 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 38 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-compartment 11 according to 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-compartment 11 according to their personal needs to select the corresponding cleaning fluid. The selected cleaning fluid is transported to the base station's water replenishment system via the delivery pump 32, 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. 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 38 of the cleaning fluid supply module can also be connected to the cleaning system, allowing the cleaning fluid (such as degreasing cleaning liquid, etc.) to be injected into the clean water tank along with the injected clean water to clean the mop of the cleaning equipment.

[0088] 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.
