[0052] In addition, the terms "first", "second", etc. are used only for descriptive purposes and should not be construed as implying or suggesting relative importance or an indicated number of the technical features. Thus, the features defined with "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0053] The base station provided by the embodiments of the present application will be described.

[0054] The base station provided by the embodiments of the present application is adapted to a cleaning robot and the two are used together.

[0055] Please refer to Figures 1 to 10 , the base station includes an integrated water tank 20; the integrated water tank 20 includes a first liquid storage structure 21 and a second liquid storage structure 22, the first liquid storage structure 21 is arranged inside the second liquid storage structure 22, the first liquid storage structure 21 has flexibility and variable volume; the first liquid storage structure 21 is used for storing a first liquid, and the space between the structural wall of the first liquid storage structure 21 and the structural wall of the second liquid storage structure 22 is used for storing a second liquid; the base station is provided with a first liquid port 113 and a second liquid port, the first liquid storage structure 21 is communicated with the first liquid port 113 through a first passage, and the second liquid storage structure 22 is communicated with the second liquid port through a second passage.

[0056] The base station provided by the embodiments of the present application is provided with an integrated water tank 20, in which the first liquid storage structure 21 is arranged inside the second liquid storage structure 22, the first liquid can be stored in the first liquid storage structure 21, and the second liquid can be stored in the space between the structural wall of the first liquid storage structure 21 and the structural wall of the second liquid storage structure 22. Since the structural wall of the first liquid storage structure 21 has flexibility and variable volume, the volume of the first liquid storage structure 21 can be variable. As the first liquid in the first liquid storage structure 21 decreases, the volume of the first liquid storage structure 21 decreases, and the storage space between the structural wall of the first liquid storage structure 21 and the structural wall of the second liquid storage structure 22 increases, so that the integrated water tank 20 can store more second liquid. Conversely, as the first liquid in the first liquid storage structure 21 increases, the volume of the first liquid storage structure 21 increases, and the storage space between the structural wall of the first liquid storage structure 21 and the structural wall of the second liquid storage structure 22 decreases, so that the liquid storage device can store more first liquid.

[0057] For example, the first liquid is selected as clean water, and the second liquid is selected as wastewater. Before using the base station, clean water is stored in the first liquid storage structure 21 of the liquid collection device, maximizing the storage capacity. During base station operation, the amount of clean water used continuously increases, the volume of the first liquid storage structure 21 continuously decreases, and the storage space between the structural walls of the first liquid storage structure 21 and the second liquid storage structure 22 continuously increases. Since the amount of wastewater generated is the same as the amount of clean water used, the wastewater can be stored in the storage space between the structural walls of the first liquid storage structure 21 and the second liquid storage structure 22.

[0058] In one embodiment, the integrated water tank 20 includes a second liquid storage structure 22 and at least two first liquid storage structures 21. The at least two first liquid storage structures 21 can be arranged inside the second liquid storage structure 22 according to their usage orientation. For example, when the integrated water tank 20 is applied to a larger mopping or washing base station, at least two mopping or washing structures can be evenly distributed around the integrated water tank 20, and the at least two mopping or washing structures are respectively arranged in different orientations of the integrated water tank 20, i.e., the aforementioned usage orientations. One first liquid storage structure 21 is correspondingly connected to one mopping or washing structure, delivering the first liquid to the corresponding mopping or washing structure nearby.

[0059] In one embodiment, the integrated water tank 20 includes a first liquid storage structure 21, a second liquid storage structure 22, and a third liquid storage structure. The first liquid storage structure 21 and the third liquid storage structure are flexible and have variable volumes. The space between the structural wall of the first liquid storage structure 21 and the structural wall of the second liquid storage structure 22 is used to store a second liquid, and the space between the structural wall of the third liquid storage structure and the structural wall of the second liquid storage structure 22 is used to store a second liquid. The first liquid storage structure 21 is used to store a first liquid, and the third liquid storage structure is used to store a third liquid.

[0060] For example, the base station can be preferably a mopping or washing base station, the first liquid can be preferably clean water, the second liquid can be preferably sewage, and the third liquid can be preferably a disinfectant.

[0061] Reference Figure 1 and Figure 2 As shown, in one embodiment, the base station is provided with a cleaning station 111 and a cleaning structure installed below the cleaning station 111. The cleaning structure is used to clean the parts to be cleaned of the cleaning robot. The parts to be cleaned include, but are not limited to, cleaning components and driving components. The cleaning components include, but are not limited to, sweeping components and mopping components. The driving components include, but are not limited to, driving wheels and sprockets.

[0062] The cleaning station 111 is used for parking the cleaning robot, and the first liquid port 113 and the second liquid port are respectively communicated with the cleaning station 111. The first liquid from the first liquid storage structure 21 is supplied to the cleaning station 111 through the first liquid port 113, and the cleaning structure below the cleaning station 111 receives the first liquid to wet it, thereby cleaning the cleaning part of the cleaning robot. After cleaning, the second liquid is generated, and the second liquid from the cleaning station 111 is collected to the space between the structure wall of the first liquid storage structure 21 and the structure wall of the second liquid storage structure 22 through the second liquid port.

[0063] In the preferred embodiment, the first liquid port 113 is arranged above the cleaning station 111, and the clean water is supplied to the cleaning station 111 in the form of liquid drops. The second liquid port is arranged below the cleaning station 111, and the dirty water is sucked away from the cleaning station 111 in the form of suction.

[0064] Specifically, the cleaning slot 112 is preferably arranged on the cleaning station 111. When the cleaning part of the cleaning robot is parked in the cleaning station 111, the cleaning part of the cleaning robot can extend into the cleaning slot 112. In this way, the dirty water can be prevented from flowing everywhere, and the collection of the dirty water is facilitated. In addition, the cleaning liquid or the dirty water splashed by the cleaning part of the cleaning robot can be effectively blocked.

[0065] Further preferably, the first liquid storage structure 21 is a flexible liquid storage bag, and the first liquid storage structure 21 is embedded in the second liquid storage structure 22.

[0066] In the embodiment, the base station includes a base station body 10, and the base station body 10 includes a horizontal part 11 and a vertical part 12. The vertical part 12 is arranged at one end of the horizontal part 11, and the two parts define the cleaning station 111. The vertical part 12 is provided with a water tank support 121, and the integrated water tank 20 is detachably inserted into the water tank support 121. The first liquid port 113 is arranged on the vertical part 12 and can drip liquid from top to bottom. The second liquid port is arranged on the horizontal part 11, and specifically can be arranged below the cleaning station 111 and can receive the second liquid from the cleaning station 111.

[0067] The first liquid storage structure 21 is provided with a liquid outlet 211, and the second liquid storage structure 22 is provided with a liquid outlet structure 223. The liquid outlet structure 223 is provided with a liquid outlet hole 224, and the liquid outlet 211 and the liquid outlet hole 224 are communicated through a liquid outlet passage. The liquid outlet structure 223 is detachably inserted into the water tank support 121, and the liquid outlet hole 224 and the first liquid port 113 are directly or indirectly communicated. The first passage at least includes the liquid outlet 211, the liquid outlet passage and the liquid outlet hole 224 which are communicated in sequence.

[0068] In existing technology, the water tank used to store clean water has its outlet connected to the drip port of the base station via a connecting structure. Clean water flows out of the tank and is then supplied to the drip port via the connecting structure, which in turn supplies the clean water to the cleaning tank 112. However, the water tank needs to be removed from and placed back into the base station frequently. When removing the water tank, the user must disassemble the connecting structure to successfully retrieve it from the base station; when placing the water tank back into the base station, the user must reinstall the connecting structure to ensure a normal supply of clean water. Therefore, the design of the connecting structure complicates the operation of removing and placing the water tank, reduces the convenience for users using the base station and the cleaning robot, and consequently diminishes the user experience.

[0069] In this embodiment, the integrated water tank 20 is detachably inserted into the water tank bracket 121, and the liquid outlet structure 223 of the second liquid storage structure 22 is also detachably inserted into the water tank bracket 121. This insertion allows direct or indirect communication between the liquid outlet 224 and the first liquid port 113. When removing the water tank, the user does not need to dismantle the structure; they only need to use external force to break free from the insertion force between the water tank and the water tank bracket 121 to successfully remove the water tank from the base station. When placing the water tank into the base station, no structural installation is required; simply align the water tank and insert it into the water tank bracket 121. Therefore, based on the detachable insertion of the integrated water tank 20, the insertion of the water tank into the water tank bracket 121 simplifies the retrieval and placement operations, improves the convenience for users using the base station and the cleaning robot, and thus enhances the user experience.

[0070] Among them, reference Figure 2 and Figure 3 As shown, the outer contour of the second liquid storage structure 22 is adapted to the inner contour of the water tank support 121. The second liquid storage structure 22 has an upper opening 221. On the second liquid storage structure 22, a portion of the structural wall adjacent to the upper opening 221 extends outward toward the outer side of the second liquid storage structure 22, forming a first water platform structure 222. Correspondingly, a second water platform structure 222 adapted to the first water platform structure 222 extends from the inner sidewall of the water tank support 121. The first water platform structure 222 is located directly above the second water platform structure 222. The liquid outlet structure 223 is provided on the first water platform structure 222, and the axis of the liquid outlet hole 224 is vertically arranged. The upper opening of the liquid outlet hole 224 is located above the first water platform structure 222, and the lower opening of the liquid outlet hole 224 is located below the first water platform structure 222.

[0071] Reference Figure 2As shown, the base station body 10 is provided with a liquid guide structure 13, preferably a pipe structure. The liquid guide structure 13 is provided with a liquid guide passage extending from top to bottom, and has a first port 131 and a second port communicated with the first port 131 through the liquid guide passage. The first port 131 is located above the second water platform structure 122, and the second port is located below the first port 131 and above the first liquid port 113. The liquid outlet structure 223 is detachably inserted into the first port 131 through the lower hole of the liquid outlet hole 224, so that the liquid outlet hole 224 and the first port 131 are communicated, and the liquid outlet structure 223 is communicated with the liquid outlet 211 of the first liquid storage structure 21 through the upper hole of the liquid outlet hole 224, while the first liquid port 113 is directly or indirectly communicated with the second port. The first passage at least includes the liquid outlet 211, the liquid outlet passage, the liquid outlet hole 224, the first port 131, the liquid guide passage and the second port communicated in sequence.

[0072] Referring to Figure 3 As shown, the second liquid storage structure 22 is further provided with a suction structure 225 provided with a suction port communicated with the second liquid below. The second passage at least includes the suction port, and the second liquid is guided by the second liquid port to the suction port, and then collected in the space between the structure wall of the second liquid storage structure 22 and the first liquid storage structure 21.

[0073] Referring to Figures 3 to 10 As shown, in a specific embodiment, the integrated water tank 20 further includes a connecting piece 23 provided on the outer side of the first liquid storage structure 21. The connecting piece 23 has a first end and a second end 232 spaced from the first end. The first end is provided on the liquid outlet 211, and the first end is provided with a first connecting passage 2312a communicated with the liquid outlet 211. The second end 232 is connected to the liquid outlet structure 223, and the second end 232 is provided with a second connecting passage 2321a communicated with the liquid outlet hole 224. The first connecting passage 2312a and the second connecting passage 2321a are communicated through an intermediate passage 2351 provided on the connecting piece 23. The liquid outlet passage includes the first connecting passage 2312a, the intermediate passage 2351 and the second connecting passage 2321a communicated in sequence.

[0074] Connector 23 serves as the guide component for the first liquid, drawing the first liquid out of the first liquid storage structure 21 and guiding it to the outside of the second liquid storage structure 22. The liquid outlet structure 223 on the structural wall of the second liquid storage structure 22 serves as the exit point for the first liquid from the integrated water tank. At the same time, the liquid outlet structure 223 serves as a detachable insertion point with the water tank bracket 121. This achieves the drawing out of the first liquid from the integrated water tank 20 to the water tank bracket 121, and then supplying it to the first liquid outlet 113 and the cleaning station 111. It also achieves a detachable connection between the drawing out position and the water tank bracket 121, making the integrated water tank 20 easy to pick up and put down.

[0075] In a preferred embodiment, the first end is detachably disposed on the liquid outlet 211, and the second end 232 is detachably connected to the liquid outlet structure 223. In this embodiment, the connector 23 is an integrally molded component, which is detachably and washably installed between the liquid outlet 211 and the liquid outlet structure 223 for easy replacement and maintenance.

[0076] Combination Figure 5 , Figures 7 to 10 As shown in the specific embodiment, the first end is provided with a first annular structure 2311 and a first core rod structure 2312. The first core rod structure 2312 is located inside the first annular structure 2311 and the two are coaxial. A first connecting passage 2312a is provided in the first core rod structure 2312 and is axially connected. The first liquid storage structure 21 is provided with a second annular structure 213, which is arranged around the periphery of the liquid outlet 211. The first annular structure 2311 and the second annular structure 213 are detachably sleeved together.
