[0006] This disclosure relates to the field of cleaning equipment technology, and more particularly to a base station and a cleaning system. Background Technology

[0007] With the improvement of people's living standards, swimming pools have become a common facility in many homes and public places. To maintain the cleanliness of swimming pools, pool robots, as an automated cleaning device, are widely used. During the use of pool robots, the filter box, as a key component for collecting impurities, is crucial, and its cleaning and maintenance directly affect the robot's working efficiency and lifespan.

[0008] Currently, pool robots on the market are usually equipped with a detachable first filter box for collecting trash in the pool. In order to facilitate the cleaning of trash in the first filter box of the pool robot, existing technology has a base station that transfers the trash in the first filter box into the inner cavity of the base station and then discharges the trash outside the base station. That is, the base station only serves as a transition channel to transfer the trash in the first filter box outside the base station. If the trash is discharged directly from the outside of the base station into the outdoors, sewers, or pools, it can easily cause secondary pollution. Summary of the Invention

[0009] In view of this, the present disclosure provides a base station and a cleaning system to solve the problem that secondary pollution is easily caused when garbage is emptied from the first filter box in the pool robot in the prior art, resulting in a poor user experience.

[0010] A first aspect of this disclosure provides a base station, the base station comprising:

[0011] Base station body;

[0012] The second filtering assembly includes at least a second filter box, and at least a portion of the second filter box is disposed within the base station body;

[0013] The second filter box has a third inlet, which allows the dust-laden water from the first filter box inside the pool robot to flow into the second filter box. The second filter box filters the dust-laden water entering it, leaving the debris in the water inside. The filtered water is then discharged from the base station body.

[0014] A second aspect of this disclosure provides a cleaning system, the cleaning system comprising:

[0015] A base station, wherein the base station is the base station described in the first aspect; and a swimming pool robot;

[0016] The pool robot includes:

[0017] The first filter box is at least partially located within the main body;

[0018] The third opening is at least partially located at the bottom of the first filter box;

[0019] A first bottom cover is movably disposed on the third opening for opening or closing the third opening;

[0020] When the pool robot stops on the base station body, the first bottom cover opens the third opening, which is connected to the third inlet, so that the dust-laden water in the first filter box can flow into the second filter box.

[0021] The beneficial effects of the embodiments disclosed herein compared to the prior art are as follows:

[0022] The base station and cleaning system disclosed herein include a base station body and a second filter assembly. The second filter assembly includes at least a second filter box, at least a portion of which is disposed within the base station body. The second filter box has a third inlet for the dust-laden water flow from the first filter box inside the pool robot to enter the second filter box. The second filter box filters the dust-laden water flow entering it, retaining debris within the second filter box, while the filtered water flow is discharged from the base station body. By incorporating a second filter box within the base station and utilizing it to collect debris from the first filter box inside the pool robot, secondary pollution from debris is effectively avoided, significantly improving the user experience.

[0077] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, so as to provide a thorough understanding of the embodiments of this disclosure. However, those skilled in the art will understand that this disclosure may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this disclosure with unnecessary detail.

[0078] As shown in Figures 32 and 33, this disclosure provides a base station and a cleaning system. The cleaning system includes a pool robot 1000 and a base station 2000. The base station is used at least to clean the first filter box 1051 of the pool robot, so that debris in the first filter box is transferred from the pool robot or temporarily stored in the base station.

[0079] In some embodiments, the base station includes a base station body, a first nozzle 2173, and a second filter box 21102. The first nozzle cleans the first filter box by spraying liquid onto it. When the pool robot automatically returns to the base station body or is placed on it by the user, liquid is sprayed through the first nozzle 2173 to clean the first filter box. Debris in the first filter box falls into the second filter box under the influence of the liquid and gravity, thus transferring the debris from the first filter box to the second filter box. No user intervention is required during the cleaning process of the first filter box, achieving automatic cleaning.

[0080] The pool robot 1000 is used to perform cleaning, disinfection, and rescue tasks in a target area. The target area can be any water-containing area where the pool robot 1000 can move. For example, the target area can include, but is not limited to, swimming pools, water tanks, oil wells, sewers, etc. The following description uses a swimming pool (or water tank) as an example. For a swimming pool, the pool includes at least a bottom and pool walls.

[0081] In some embodiments, the pool robot includes a first filter box 1051, at least a portion of which is disposed within a first body 1001. The first filter box includes a third opening 10531 and a first bottom cover 1054. At least a portion of the third opening is disposed on the bottom of the first filter box, and the first bottom cover is movably disposed on the third opening for opening or closing the third opening. When the pool robot stops on the base station body, the first bottom cover opens the third opening, and the third opening communicates with the third inlet 21101 of the second filter box 21102, allowing dust-laden water from the first filter box to flow into the second filter box.

[0082] As shown in Figures 43 and 44, the base station 2000 includes a base station body 20001 and a second filtering assembly. The second filtering assembly includes at least a second filter box 21102, at least a portion of which is disposed within the base station body. The second filter box has a third inlet 21101, through which dust-laden water from the first filter box inside the pool robot flows into the second filter box. The second filter box filters the dust-laden water entering it, leaving debris in the water within the second filter box, while the filtered water is discharged from the base station body.

[0083] In some embodiments, the base station body includes a second dust chamber 2150, and the inner cavity of the second dust chamber serves as a third receiving cavity 2054. The second filter box is removably disposed within the third receiving cavity of the base station body, making it convenient for the user to pull the second filter box out of the base station body and clean out the waste collected inside the second filter box.

[0084] In some embodiments, the second filter box has a first state and a second state relative to the base station body. In the first state, the second filter box is located within the base station body. In the second state, at least a portion of the second filter box is removed from the base station body. Further, in some embodiments, in the second state, the second filter box is completely removed from the base station body, thus leaving the base station.

[0085] In some embodiments, the base station body includes a fourth opening 2055, which connects the third receiving cavity to the outside. The fourth opening is also connected to a third inlet, allowing dust-laden water from the first filter box to flow into the second filter box through the fourth opening and the third inlet.

[0086] Furthermore, in some embodiments, the base station body also includes at least one ninth opening 2056, which communicates the third receiving cavity with the outside. The second filter box is installed into or removed from the third receiving cavity through the ninth opening. In a first state, the second filter box is located inside the third receiving cavity. In a second state, at least a portion of the second filter box is located outside the ninth opening. The ninth opening facilitates the user's removal and placement of the second filter box from the side wall of the base station body. For example, the ninth opening is located on the left or right side wall, or the front or rear side wall of the base station body.

[0087] In other embodiments, a ninth opening may be provided on the top of the base station body, allowing the user to remove the second filter box from the third receiving cavity from the top of the base station body, or to place it into the third receiving cavity. For example, in some embodiments, the ninth opening is the aforementioned fourth opening. Alternatively, the ninth opening may be different from the aforementioned fourth opening, and the ninth opening and the fourth opening may be offset from each other on the top of the base station body.

[0088] As shown in Figures 9 to 28, in some embodiments, the base station further includes at least one sliding mechanism. The sliding mechanism allows the second filter box to slide within the third receiving cavity to switch between a first state and a second state. Specifically, in some embodiments, at least two sliding mechanisms are included, symmetrically arranged, and located on opposite sides of the second filter box.

[0089] The sliding mechanism includes at least one first sliding member and at least one first supporting member. The first sliding member is disposed on the second filter box. The first supporting member is disposed on the third receiving cavity and extends along the sliding direction of the second filter box. The first sliding member can slide on the first supporting member, enabling the second filter box to slide within the third receiving cavity. Furthermore, the first supporting member can raise the second filter box, ensuring a gap between the bottom of the second filter box and the bottom of the third receiving cavity, facilitating the flow of filtered liquid from the second filter box to the bottom of the third receiving cavity and subsequently discharged outside the base station.

[0090] In a specific example, the first sliding member may include, but is not limited to, a slider or a pulley; correspondingly, the first support member may include, but is not limited to, a slide rail adapted to the slider, or a guide rail adapted to the pulley. The sliding mechanism facilitates the quick extraction or insertion of the second filter box from the third receiving cavity. The guide rail or slide rail may be disposed on the third receiving cavity, and the slider or pulley corresponding to the guide rail or slide rail may be disposed on the second filter box.

[0091] In some embodiments, a first slider is disposed on the side of the second filter cartridge. A first support is disposed on the side wall of the third receiving cavity. The first support has at least a first support surface 10019, which extends along the sliding direction of the second filter cartridge. The first slider slidably overlaps the first support surface.

[0092] In some embodiments, the first support surface communicates with the ninth opening so that the first slider engages with the first support surface and the second filter box slides into the third receiving cavity; and the first slider slides away from the first support surface so that the second filter box is completely withdrawn from the third receiving cavity.

[0093] In one specific example, the first slider includes a first outer edge 211021 that protrudes outwardly onto the side of the second filter box. The first outer edge slidably overlaps the first support surface. That is, through the relative sliding between the first outer edge and the first support surface, the second filter box can be slidably disposed within the third receiving cavity.

[0094] In one specific example, the first sliding member includes a first sliding portion 21102a, which is disposed on the second filter box along a side portion substantially parallel to the second filter box. The first sliding portion slidably overlaps the first support surface. The second filter box includes a second outer edge 211022, which protrudes outwardly from the side portion of the second filter box, and the first sliding portion is disposed on the second outer edge. Further, in some embodiments, the second outer edge and the side portion of the second filter box are transitionally connected by an inclined surface 211023. Here, "substantially parallel" means that the included angle between the two surfaces is less than or equal to 30 degrees.

[0095] As shown in Figure 17, in some embodiments, the first support member includes at least one first step 100191, which may be disposed on the side wall of the third receiving cavity. The first step surface of the first step serves as the first support surface. The second filter box can be pulled out of the third receiving cavity or pushed into the third receiving cavity by the relative sliding of the first slider on the first step.

[0096] Specifically, when the first support is a first step, one end of the first step is connected to the ninth opening so that the first sliding member can slide out from this end of the step and the second filter box can leave the base station; or, the first sliding member can slide in from this end and the second filter box can be installed into the third receiving cavity.

[0097] As shown in Figure 19, in some embodiments, the first support member includes at least one groove 100192, which is disposed on the side wall of the third receiving cavity. One wall of the groove serves as a first support surface, and the first sliding member is embedded in the groove and slidably overlaps the first support surface.

[0098] Wherein, when the first support is a chute, one end of the chute is a first open opening, which is connected to the ninth opening, so that the first sliding member can slide out of the chute and the second filter box can leave the base station; or, so that the first sliding member can slide into the chute and the second filter box can be installed into the third receiving cavity.

[0099] In some embodiments, referring to FIG13, the first support surface 10019 may further include a first segment 10019a and a second segment 10019b. The first segment is closer to the ninth opening than the second segment. The first segment is a slope, an arc, or an incline, which facilitates the second filter box sliding into the third receiving cavity. That is, the function of the first segment is to guide and position the second filter box when it enters the third receiving cavity. The second segment is a plane, which ensures that the second filter box is placed horizontally after it is fully entered into the third receiving cavity, thereby ensuring that the third inlet is aligned with the fourth opening, and thus ensuring that the waste can fall accurately into the second filter box.

[0100] As shown in Figures 14 and 18, in some embodiments, the base station further includes a positioning mechanism 2060 for knowing or detecting whether the second filter box is installed in the third receiving cavity.

[0101] As shown in Figures 13 and 17, in some embodiments, the positioning mechanism includes a first protrusion 20601 and a second protrusion 20602. The first protrusion can protrude outwardly from the first sliding member, while the second protrusion can protrude from the sidewall of the third receiving cavity. The second protrusion is movably disposed on the sidewall of the third receiving cavity, which reduces damage to the first protrusion when it slides against the second protrusion.

[0102] During the sliding process of the first slider on the first support surface, preferably, the first slider does not contact the second protrusion. The first slider causes the first protrusion to slide against the second protrusion with an interference fit. After passing or sliding over the second protrusion, one end of the first protrusion abuts against the second protrusion along the sliding direction of the first slider. The second protrusion prevents the first protrusion from sliding outward from the third receiving cavity. When the first protrusion slides against the second protrusion with an interference fit, it provides tactile feedback. That is, when the user pushes the second filter box into the third receiving cavity, the user can feel the contact between the first and second protrusions, or even when the first protrusion passes or slides over the second protrusion. Moreover, the interference fit between the first and second protrusions effectively confines the second filter box within the third receiving cavity, preventing it from sliding out. It should be noted that the number of first and second protrusions can be one or more; the specific number is not specifically limited here.

[0103] In some embodiments, the positioning mechanism includes a fifth positioning detection component for detecting whether the second filter cartridge is installed in the third receiving cavity.

[0104] In some embodiments, as shown in Figures 22 and 23, the fifth positioning detection component includes at least one of a sensing component, an inductive component, and a switching component. The sensing component includes a sensing element (not shown) and a sensing mating element 20603. One of the sensing element and the sensing mating element is located on the second filter box, and the other is located on the third receiving cavity. For example, one of the sensing element and the sensing mating element is a Hall sensor, and the other is an iron element. One of the sensing element and the sensing mating element is located on the side wall of the second filter box, and correspondingly, the other is located on the side wall of the third or fourth receiving cavity 200011; or, one of the sensing element and the sensing mating element is located on the bottom of the second filter box, and correspondingly, the other is located on the bottom of the third receiving cavity. The fifth positioning detection component ensures that the second filter box is in position through electronic detection, and the cleaning system can only run relevant procedures after the second filter box is in position.

[0105] In this example, the positioning mechanism can accurately detect whether the second filter box is installed in place. When the second filter box is installed in the correct position, the first protrusion and the second protrusion can accurately match, or the sensing element and the sensing mating element can sense each other normally, ensuring that the second filter box is in the appropriate position within the base station, guaranteeing the normal operation of filtering and pulling operations, and improving the reliability and security of base station use.

[0106] As shown in Figure 8-1, in some embodiments, the second filter box includes a second frame 2112 and at least one second filter screen (not shown in the figure). The second frame has at least one through hole 211221. The at least one second filter screen is disposed on the second frame, at least covering the through hole to form a filter surface. The second filter box also includes a third inlet, at least a portion of which is disposed on the top of the second frame. In one specific example, the third inlet is disposed on the top of the second frame. In another specific example, the third inlet is partially disposed on the top of the second frame and partially disposed on the side of the second frame.

[0107] In other embodiments, the second filter box includes a box body and a first filter bag. The box body has at least one opening. The first filter bag is at least partially disposed within the box body and is used to receive and filter the dust-laden water flow from the first filter box. The filtered liquid enters the box body and exits from the opening. The second filter box also includes a third inlet, at least partially disposed at the top of the box body. In one specific example, the third inlet is located at the top of the box body. In another specific example, the third inlet is partially located at the top of the box body and partially located at the side of the box body. It should be noted that in this case, the box body does not have a filtering function, but it can discharge the filtered water flow to the outside of the box body.

[0108] In a specific example, the second filter box 21102 includes a second frame 2112 and a second filter screen. The second filter screen is disposed on the second frame to form a filter surface. Alternatively, the second filter screen can be replaced with filter cotton, which can be disposed outside or inside the second frame. The second frame 2112 includes multiple side panels 21121 (such as a front side panel, a left side panel, a rear side panel, and a right side panel) and a bottom plate 21122, wherein the multiple side panels 21121 are detachably or non-detachably connected end to end, and together with the bottom plate 21122 form a frame structure that is hollow inside and open at the top.

[0109] The base plate 21122 has multiple through holes 211221. The through holes are in the shape of a square or a square, etc. The second filter screen 2113 can be a single piece set on the second frame 2112 and cover the multiple through holes 211221. Alternatively, there can be multiple second filter screens 2113, which are arranged one-to-one on the multiple through holes 211221.

[0110] In this example, the second frame 2112 provides stable structural support for the entire second filter box 21102, ensuring that it will not easily deform during use. The through holes 211221 on the base plate 21122 allow liquid to pass through, while the second filter screen 2113 can intercept solid impurities in the object to be cleaned, achieving solid-liquid separation, effectively improving the filtration effect on the object to be cleaned by the pool robot, and facilitating subsequent separate processing of solids and liquids.

[0111] In some embodiments, since the second filter box needs to be manually emptied by the user after it becomes full, the volume of the second filter box is larger than that of the first filter box to reduce the frequency of cleaning. That is, the volume of the second filter chamber of the second filter box is larger than the volume of the first filter chamber of the first filter box. For example, if the volume of the second filter box is 1.5 times, 2 times, 3 times, 4 times, 5 times, or 6 times the volume of the first filter box, then the second filter box can temporarily store the debris from multiple cleanings of the first filter box. This avoids the need for the user to empty the debris from the second filter box every time the first filter box is cleaned. Instead, the user only needs to clean the second filter box once after cleaning the first filter box multiple times, reducing the frequency of cleaning the second filter box and thus improving the dust collection efficiency of the base station.

[0112] In some embodiments, as shown in FIG8-1, the second frame or housing includes a plurality of side panels 21121, which include a front side panel 21121a, a left side panel 21121b, a rear side panel 21121c, and a right side panel 21121d connected in sequence. The front side panel is closer to the ninth opening than the rear side panel. The top of each side panel of the second frame or housing extends in a direction away from the center of the second frame or housing to form a second outer edge 211022, which defines the drawstring mechanism of the second filter bag.

[0113] As shown in Figures 9 and 15, in some embodiments, the top of each side plate of the second frame 2112 or the box body can be transitionally connected to the second outer edge 211022 via an inclined surface 211023, which can guide garbage and liquid falling on it into the second filter box. In some embodiments, drainage holes 21123 are also formed on the inclined surface for draining liquid falling on the inclined surface from the second filter box or draining liquid from inside the second filter box.

[0114] As shown in Figures 8-1 and 8-2, in some embodiments, first reinforcing ribs 2115 are provided on multiple side plates of the second frame or box. The first reinforcing ribs 2115 can extend from the top to the bottom of the side plate. The first reinforcing ribs enhance the structural strength of the second frame or box, preventing the side plates from deforming due to stress during the removal or placement of the second filter box, thus ensuring the overall structural stability of the second filter box.

[0115] In some embodiments, a second reinforcing rib 211225 is provided on the base plate 21122 of the second frame or box. The second reinforcing ribs are arranged in a crisscross pattern, so that the outer periphery of each through hole or opening is surrounded by a second reinforcing rib. The interlacing arrangement of the second reinforcing ribs can form a stable reinforcing network, which greatly enhances the structural strength of the base plate and can withstand the weight of the object to be cleaned and the impact force during the extraction process.

[0116] In this embodiment, at least one guide plate 211222 may also be provided on the base plate. The guide plate is provided near the periphery of the base plate and is located on opposite sides of the base plate along the direction from the front side plate to the rear side plate. The guide plate 211222 includes a first end and a second end. The first end is located further away from the second reinforcing rib than the second end. The first end of the guide plate is inclined towards the second end, and the thickness of the second end is greater than the thickness of the first end, which is beneficial for the accurate alignment of the second filter box 21102 when it is pulled out, and prevents jamming.

[0117] In some embodiments, as shown in Figures 16 and 18, the second filter cartridge further includes a first handle 2114 disposed on the side of the second frame or housing, for a user to operate on the first handle to slide the second filter cartridge, thereby enabling the second filter cartridge to switch between a first state and a second state. In the first state, the first handle is exposed to the environment. Further, in some embodiments, in the first state, the second filter cartridge is located within a third receiving cavity. The first handle is exposed to the environment through a ninth opening. In the second state, at least a portion of the second filter cartridge is located outside the ninth opening.

[0118] In a specific example, as shown in Figure 18, a first handle 2114 is disposed on the second filter box and located on the outside of the second filter box. For example, the first handle 2114 protrudes outward and is disposed on the front side plate 21121a. The first handle provides the user with a convenient part to grasp and move the second filter box, allowing the user to easily pull the second filter box out of or into the third receiving cavity.

[0119] In a specific example, referring to Figures 8-1 to 8-2, the second filter cartridge further includes a second extension 2117, which is disposed on the second filter cartridge along a side portion generally parallel to the second filter cartridge, for example, generally parallel to the front side panel. In this embodiment, the front side panel, the adjacent second outer edge, and the second extension form a recessed region, at least a portion of which serves as a first handle 2114. This arrangement allows the user to easily operate the first handle to drive the second filter cartridge to slide, thereby switching the second filter cartridge between a first state and a second state.

[0120] Furthermore, in some embodiments, referring to Figures 9, 14, and 15, a protrusion 2117a is provided on the inclined surface between the front side plate and the second outer edge, and a first groove 2117b is formed on the back side corresponding to this part. This arrangement can limit and position the first handle, and also provide some space for the user's hand when the user pulls out the second filter box, thus improving the user experience.

[0121] Furthermore, in some embodiments, referring to Figure 8-2, a third reinforcing rib 2117c is also formed within the first groove, which enhances the structural strength of the first handle. The bottom of the third reinforcing rib is higher than the bottom of the second extension. Further, in some embodiments, the third reinforcing rib forms a third notch (not shown in the figure), which is low at both ends and high in the middle, allowing the user's palm to better conform to the handle surface during the pulling process, providing a comfortable grip. Further, in some embodiments, when the distance between two adjacent reinforcing ribs is approximately greater than the width of a finger, a horizontal connecting rod 2117d is provided between the two adjacent reinforcing ribs to prevent fingers from getting stuck between them and effectively enhance the overall rigidity and stability of the first handle.

[0122] In some embodiments, the second filter box further includes a second handle 2116. The second handle is located on the second frame or box body, allowing the second filter box to exit the base station body, and the user can use the second handle to lift the second filter box. That is, the second handle is used by the user to lift the second filter box after it leaves the base station. It should be noted that in some embodiments, when there is a large amount of waste temporarily stored inside the second filter box, making it heavy and difficult for the user to lift, the second handle can also be used by a robotic arm or an industrial robot to lift the second filter box, thereby reducing the user's workload. After the waste inside the second filter box is cleaned, the user can then lift the second filter box using the second handle and place it into the third receiving cavity of the base station.

[0123] In some embodiments, a first region is formed between the first sliding portion and the side of its adjacent second filter cartridge, at least a portion of the first region serving as a second handle.

[0124] In some embodiments, the second filter cartridge further includes a second outer edge connected to a first sliding portion, the first sliding portion, together with the adjacent second outer edge and the side portion of the second filter cartridge, forming a first region. At least a portion of the first region serves as a second handle. For example, the left side plate, the adjacent second outer edge, and the first sliding portion form a first region, and the right side plate, the adjacent second outer edge, and the first sliding portion form a first region, wherein at least a portion of the first region serves as a second handle.

[0125] In some embodiments, the second filter box further includes at least one first reinforcing rib, which is disposed in the first region. The first sliding portion, together with the adjacent first reinforcing rib and the side portion of the second filter box, forms the first region. At least a portion of the first region serves as the second handle. The first reinforcing rib can transfer the force on the second handle to the side plate, enhancing the structural strength of the second handle, preventing damage to the second handle during lifting, and further improving the overall stability of the second filter box.

[0126] In some embodiments, the second filter cartridge includes both at least one first reinforcing rib and a second outer edge. The first sliding portion, together with its adjacent first reinforcing rib, second outer edge, and side portion of the second filter cartridge, may form a first region. At least a portion of the first region serves as a second handle.

[0127] Further, in some embodiments, as shown in Figure 8-1, the first reinforcing ribs in the first region are arranged at intervals along the direction from the rear side plate to the front side plate, and each first reinforcing rib includes a flat section 2115a and an arc section 2115b on the side facing the bottom plate. One end of the flat section is connected to the first sliding part, and the other end is connected to one end of the arc section. The other end of the arc section is connected to the left side plate or the right side plate. Along the direction from the top of the second frame 2112 or the box body to its bottom, the distance from the lowest point of the arc section to the bottom plate is less than the distance from the bottom of the flat section to the bottom plate, and the distance from the bottom of the flat section to the bottom plate is greater than or equal to the distance from the bottom of the first sliding part to the bottom plate. The design of the flat and arc sections of the first reinforcing ribs in the first region allows the user's palm to better fit the handle surface when gripping the second handle, providing a comfortable grip. The arc section can provide the user with a warning to avoid the user's fingers hitting the left and right side plates when gripping the second handle.

[0128] In some embodiments, when the distance between two adjacent first reinforcing ribs in the first region is greater than a set distance (e.g., the width of a finger), a horizontal connecting rod 2117d is provided between the two adjacent first reinforcing ribs to effectively enhance the overall rigidity and stability of the second handle. The horizontal connecting rod acts as a reinforcement when the distance between adjacent first reinforcing ribs is large, enhancing the overall structural strength of the second handle, preventing the first reinforcing ribs from deforming or being damaged under stress, and also preventing fingers from getting stuck between two adjacent first reinforcing ribs, thus improving the user's comfort when lifting the second filter box.

[0129] It should be noted that when the distance between two adjacent first reinforcing ribs in the first region is less than the set distance, multiple first reinforcing ribs can be arranged in a dense manner, which can also improve the overall structural strength of the second handle.

[0130] The reasonable arrangement and placement of the aforementioned second handle not only does not hinder the installation and use of other components, but also facilitates user operation and improves the user experience.

[0131] In some embodiments, as shown in Figures 22, 23, and 25 to 28, a second handle is rotatably disposed on the upper part of the second frame or housing. The second handle has a third state and a fourth state, which can be switched by rotating the second handle. The second handle has a lifting portion for the user to lift the second handle. In the third state, the top of the lifting portion is not higher than the top of the third inlet. In the fourth state, at least a portion of the lifting portion is higher than the top of the third inlet and is located outside the third inlet. When the second filter box is located within the base station body, the second handle is in the third state. When at least a portion of the second filter box is removed from the base station body, the second handle can switch from the third state to the fourth state.

[0132] In one specific example, the two ends of the second handle are rotatably mounted on the left and right side plates, respectively. The second handle has a third state and a fourth state, which can be switched by rotating the second handle. In the third state, the top of the lifting part is not higher than the top of the third inlet, and the second handle can be concealed on the side wall of the third inlet. In the fourth state, at least part of the lifting part is higher than the top of the third inlet and is located outside the third inlet, so that the user can lift the second filter box through the lifting part.

[0133] Furthermore, in some embodiments, as shown in Figures 22, 23, and 32, the upper part of the second frame or box has a second step 2112a. In a third state, at least a portion of the second handle rests on the second step surface of the second step. In a fourth state, the lifting portion moves away from the second step surface. Specifically, in the third state, at least a portion of the second handle rests on the second step surface of the second step, and the second step supports the second handle, preventing it from falling under its own weight.

[0134] The second handle is rotatably located inside the second frame or the box, and the second step is also located inside the second frame or the box. Alternatively, the second handle is rotatably located outside the second frame or the box, and the second step is also located outside the second frame or the box. Placing the second handle outside the second frame or the box prevents debris falling from the first filter box from landing on the second handle and the second step.

[0135] In this example, the rotatable design of the second handle allows it to be hidden when not in use, saving space and maintaining the neat appearance of the base station. When in use, users can easily lift the second filter box to the designated location and empty it by pulling the second handle, providing a labor-saving operation method, especially for the heavier second filter box, reducing the difficulty of operation for users.

[0136] As shown in Figures 22 and 31, in some embodiments, the second filter box 21102 further includes a cover plate 2140, which is movably disposed on the second frame or box body. The cover plate has a fifth state and a sixth state. When the cover plate is in the fifth state, the cover plate covers at least a portion of the third inlet. When the cover plate is in the sixth state, the cover plate opens at least a portion of the third inlet. The cover plate is in the fifth state when the second filter box is located within the base station body. The cover plate is in the sixth state when at least a portion of the second filter box is removed from the base station body.

[0137] In a specific example, one end of the cover is located between and rotatably mounted on the left and right side panels, while the other end is movably mounted on the second frame or housing. In the fifth state, the cover covers at least a portion of the third inlet, preventing splashing of dust-laden liquid. In the sixth state, the cover opens at least a portion of the third inlet, facilitating the discharge of waste from both sides of the cover.

[0138] Specifically, in the fifth state, the cover is positioned close to the front or rear side panel and is fixed to the front or rear side panel by means of a protrusion 2141 and a latch 2142. The protrusion can be located on the second filter box or the box body, while the latch is located on the cover. In the sixth state, the cover rotates to a vertical position to ensure sufficient opening area for dumping waste and to prevent the cover from obstructing waste disposal.

[0139] In some embodiments, as shown in Figures 25 and 28, a first side opening 2118 is provided on at least one side of the second frame or housing to facilitate user observation of the waste status and intervention. The second frame or housing also includes a first side cover 21121a2, which is used to open or close the first side opening. The first side opening allows the user to directly observe the condition inside the second filter box, such as the accumulation status of the waste to be cleaned.

[0140] In a specific example, as shown in Figures 25 and 28, a first side opening 2118 is provided at the front side panel of the second frame or box. The front side panel may include a front side panel body 21121a1 and a first side cover 21121a2, the first side cover being movably connected to the front side panel body to open or close the first side opening. Alternatively, the first side cover 21121a2 is movably connected to the bottom plate to open or close the first side opening.

[0141] In some embodiments, at least one side of the second frame or box body is further provided with at least one locking mechanism 2119, which is used to lock the first side cover.

[0142] In a specific example, as shown in Figures 25 to 28, there are at least two locking mechanisms 2119, respectively disposed on the left and right side panels and adapted to lock the first side cover. Each locking mechanism includes at least one locking lever 21191 and at least one locking plate 21192. The locking lever 21191 cooperates with the corresponding locking plate 21192 to lock the first side cover when closed. The locking lever is rotatably connected to either the left or right side panel. When the first side opening is opened, the locking lever is arranged in a generally vertical direction to ensure that the first side cover can be opened normally. When the first side opening is closed, the locking lever is arranged in a generally horizontal direction to ensure that the first side cover remains closed. The first side cover is rotatably connected to the top surface of the front side panel body, or rotatably connected to the bottom plate. "Generally horizontal" and "generally vertical" can refer to an angle of less than or equal to 30 degrees between the locking lever and a reference surface.

[0143] It should be noted that the first side cover can also be connected to the top or bottom surface of the front side panel body by sliding or magnetic attraction to open and close the first side opening. In addition to using a locking rod to lock the first side cover, the locking mechanism can also use magnets or other methods to lock the first side cover.

[0144] In some embodiments, as shown in FIG14, the base plate 21122 includes a slope section 211223 and a flat section 211224. The two ends of the slope section are connected to the front side plate and the flat section respectively in the direction of extension from the front side plate to the rear side plate, and the slope of the slope section is inclined from the direction from the front side plate to the flat section (i.e., inclined backward and downward).

[0145] Multiple through-holes are located on the flat section. The sloping section design utilizes gravity to facilitate the flow of the material and liquid to be cleaned towards the flat section, ensuring that the material is concentrated in the through-hole area of ​​the flat section for filtration. Furthermore, the through-holes are located on the flat section, not the sloping section, and the flat section is positioned further away from the ninth opening than the sloping section, preventing filtered liquid from flowing out of the ninth opening. The through-holes on the flat section enable more effective solid-liquid separation, improving filtration efficiency. The rational combination of the sloping and flat sections also facilitates the installation and use of the second filter box.

[0146] In some embodiments, the second filtration assembly further includes a second filter bag (not shown). At least a portion of the second filter bag is disposed within the second filter box. The second filter bag is used at least to receive and filter the dust-laden water flow from the first filter box. The second filter box is used at least to perform secondary filtration on the liquid filtered by the second filter bag. The dual-layer filtration of the second filter bag and the second filter box further improves the filtration efficiency of the waste. Furthermore, the second filter bag is detachably disposed within the second filter box for easy periodic replacement.

[0147] The second filter bag has an open end with a fifth inlet. The open end of the second filter bag is located at the third inlet, allowing the dust-laden water in the first filter box to enter the second filter bag. The open end of the second filter bag is folded outwards and fits over the third inlet of the second filter box. In one embodiment, the third inlet of the second filter box has a second outwardly extending edge, and the open end of the second filter bag is folded outwards and fits over this second outer edge.

[0148] For example, the fifth inlet is located on the top of the second filter bag. The top of the second filter bag is placed over the third inlet of the second filter box, so that the fifth inlet communicates with the fourth and third openings. Waste in the first filter box falls into the second filter bag through the third, fourth, and fifth inlets. The liquid filtered by the second filter bag undergoes secondary filtration through the second filter box, while the waste remains inside the second filter bag. Because the waste is collected in the second filter bag, the user only needs to handle the second filter bag. The second filter bag is also lightweight, making it easy for the user to dispose of the waste inside. In some embodiments, the second filter bag is a disposable filter bag. When the second filter bag is full of waste, the user simply discards it and replaces it with a new one; there is no need for the user to clean the second filter bag.

[0149] In some embodiments, the second filter bag is made of a deformable or flexible material.

[0150] In some embodiments, the second filter bag further includes a drawstring mechanism disposed at the open end of the second filter bag. The drawstring mechanism is used to close or open the fifth inlet. When the second filter box is located within the base station body, the drawstring mechanism opens the fifth inlet. When at least a portion of the second filter box is located outside the base station body, the drawstring mechanism is capable of closing the fifth inlet.

[0151] When the second filter bag is full or has collected a preset amount of waste, because it is made of deformable or flexible material, the user can operate the closing mechanism to retract or close the fifth inlet, sealing the waste inside the second filter bag to form a closed waste bag. This makes it easy for the user to remove the second filter bag from the filter box, preventing waste from falling onto the base station or the ground and causing secondary pollution. When the user needs to empty or clean the waste from the second filter bag, the user operates the closing mechanism to open the fifth inlet, allowing the waste in the second filter bag to be emptied through the fifth inlet, and the second filter bag can be reused. Alternatively, the user does not need to empty the waste from the second filter bag through the fifth inlet; the user can directly discard the second filter bag and replace it with a new one.

[0152] It should be noted that the drawstring mechanism can be any of the following: drawstring, elastic band, retainer, rubber band, draw cord, etc. Alternatively, the drawstring mechanism can even be a buckle, button, zipper, etc.

[0153] In some embodiments, the closing mechanism includes at least a strap, and an annular channel is provided at the fifth inlet of the second filter bag. The strap is disposed inside the annular channel, with a portion of the strap located outside the annular channel to facilitate user manipulation of this portion of the strap to close the fifth inlet. For example, the annular channel starts at the fifteenth inlet and ends at the sixteenth inlet, with the fifteenth and sixteenth inlets adjacent or close to each other. This portion of the strap protrudes from the fifteenth and sixteenth inlets, located outside the annular channel. When the user pulls this portion of the strap, more of the strap protrudes from the fifteenth and sixteenth inlets, causing the entire annular channel to close, thus closing the fifth inlet. Conversely, the user can leave the strap unpulled, unfolding the annular channel to open the fifth inlet. Alternatively, the middle section of the annular channel may also have a seventeenth and eighteenth inlet, adjacent or close to each other, or opposite to the fifteenth and sixteenth inlets. Two parts of the strap protrude from the fifteenth and sixteenth inlets and the seventeenth and eighteenth inlets respectively, located outside the annular channel. The user pulls these two parts of the strap to bring the entire annular channel together, closing the fifth inlet. Conversely, the user can leave the strap unpulled, unfolding the annular channel to open the fifth inlet. The strap can be completely inelastic or have low elasticity. When the strap has low elasticity, it ensures greater stability when the second filter bag is fitted onto the second filter box, preventing it from easily falling off. The strap material can be biodegradable, etc.

[0154] In some embodiments, the constriction mechanism includes at least an elastic ring. The elastic ring has a large elastic force and can automatically contract after the external force is removed. The elastic ring is entirely disposed within the annular channel. The user pulls the elastic ring outward, unfolds the annular channel, and places the annular channel onto the second filter box to open the fifth inlet. Conversely, after the external force disappears, the elastic ring automatically contracts under its own elastic force, closing the fifth inlet.

[0155] It should be noted that when the elasticity of the closing mechanism is low, it is sufficient to ensure that the second filter bag does not detach from the second filter box, but the closing mechanism will not automatically retract. In other words, the closing mechanism will keep the top opening of the second filter bag at a certain degree of openness to allow waste to enter the second filter bag.

[0156] Alternatively, if the elasticity of the closure mechanism is high, the closure mechanism can automatically contract, thereby allowing the second filter bag to be firmly fixed on the second filter box. This facilitates the entry of garbage into the second filter bag while preventing the second filter bag from falling off due to the impact of garbage.

[0157] In some embodiments, the second filter bag can be a disposable filter bag or a reusable filter bag. The filter bag material can be selected from woven fabric, non-woven fabric, filter cotton, nylon mesh, biodegradable materials, or composite filter membranes, etc.

[0158] In other embodiments, the second filter box is the first filter bag. Similar to the second filter bag described above, the first filter bag is made of a deformable or flexible material. The first filter bag can be a disposable filter bag or a filter bag that can be reused multiple times. Furthermore, to facilitate the user's cleaning of the waste inside the first filter bag, a drawstring mechanism is provided at the third inlet of the first filter bag for closing or opening the third inlet. This drawstring mechanism is the same as the drawstring mechanism of the second filter bag described above. The first filter bag and the second filter bag are the same, as described above, and will not be repeated here.

[0159] Furthermore, in some embodiments, as shown in Figures 26 and 27, the base station further includes a tray 211041. At least a portion of the tray is located below the second filter box and is used to receive at least a portion of the liquid filtered by the second filter box. The tray has at least one water outlet 211042, which communicates with a drainage assembly on the base station body, allowing the liquid filtered by the second filter box to flow out from the water outlet and then be discharged from the base station body through the drainage assembly. In this embodiment, due to the tray, the liquid filtered by the second filter box falls directly onto the tray, reducing contact between the liquid and the third receiving cavity and preventing contamination of the third receiving cavity. In addition, the tray also provides some support for the second filter box. The tray and the second filter box are removably installed in the third receiving cavity, facilitating cleaning and maintenance of the filtered liquid and the filter box by the user. Simultaneous or separate removal can be selected according to actual needs, improving the flexibility of base station use.

[0160] In other embodiments, when the second filter box is the aforementioned first filter bag, the first filter bag is disposed within a tray, and the tray supports the first filter bag. In some embodiments, the tray is removably disposed within a third receiving cavity, and the first filter bag moves synchronously with the tray to facilitate replacement of the first filter bag. Simultaneously, the tray also serves to receive at least a portion of the liquid filtered by the first filter bag. The tray may have a water outlet, which is connected to a drainage assembly, so that the liquid filtered by the first filter bag flows out through the water outlet and then is discharged from the base station body through the drainage assembly. For example, in some embodiments, the tray is a box with an opening at the top, the third inlet of the first filter bag is fitted onto the top opening of the box, the first filter bag is located inside the box, and the box supports the first filter bag. A water outlet is provided at the bottom of the box for the liquid inside the box to flow out.

[0161] In some embodiments, as shown in Figures 1 to 5, the base station body further includes a fourth baffle 200021, which is movably disposed on the base station body and used to open or close the ninth opening. When the first nozzle cleans the first filter box, the fourth baffle closes the ninth opening to prevent liquid in the third receiving cavity from splashing or flowing out from the ninth opening. When it is necessary to remove or place the second filter box, the fourth baffle is opened to expose the second filter box to the external environment, making it easier for the user to pull the second filter box out of or put it into the third receiving cavity. In some embodiments, during the process of the first nozzle spraying liquid to clean the first filter box, the fourth baffle remains closed at the ninth opening to prevent liquid in the third receiving cavity from flowing out from the ninth opening. For example, a voice prompt can be given through the speaker on the base station to remind the user that the fourth baffle should not be opened during this stage; or a prompt can be displayed on the APP of the electronic device that the fourth baffle should not be opened.

[0162] In some embodiments, the fourth baffle and the base station body can be connected in various ways, such as rotational connection, sliding connection, magnetic connection, etc.

[0163] For example, the fourth baffle is rotatably connected to the base station body via hinges, connecting shafts, or other structures. Alternatively, the fourth baffle is slidably connected to the base station body via the cooperation of a slider and a slide rail, or a gear and a rack. Or, the fourth baffle is connected to the base station body via the magnetic attraction of a magnet and iron. The following explanation uses the example of a fourth baffle rotatably mounted on the base station body.

[0164] In some embodiments, the base station further includes at least one connecting mechanism 2160 for rotatably mounting the fourth baffle on the base station body, such that the fourth baffle switches between a generally horizontal open state and a generally vertical closed state. In the open state, the fourth baffle opens the ninth opening. In the closed state, the fourth baffle closes the ninth opening. "Generally horizontal" and "generally vertical" can refer to an angle of less than or equal to 30 degrees between the fourth baffle and a reference plane.

[0165] In the open state, the fourth baffle is higher than the bottom of the base station body. And / or in the open state, the fourth baffle serves to support at least a portion of the second filter cartridge that has exited the third receiving cavity.

[0166] In a specific example, when the fourth baffle 200021 rotates outward to open the ninth opening 2056, the fourth baffle 200021 can provide a roughly horizontal support surface through the connecting mechanism. The second filter box 21102 can be fully pulled out and smoothly extracted from the third receiving cavity 2054 through the support surface, providing a convenient and safe operating platform for users to pick up, put down, and clean the second filter box 21102. Moreover, at this time, the fourth baffle is higher than the bottom of the base station body, which can ensure that the fourth baffle does not contact the ground, avoid dust and other contaminants on the fourth baffle, and prevent the fourth baffle from being damaged by impact and friction with the ground when opened.

[0167] In addition, the fourth baffle 200021, as a movable opening and closing component, can close the ninth opening 2056 when the base station is in normal use, which can protect the internal structure of the base station body 20001 and prevent dust and debris from entering; it can also be opened when the second filter box 21102 needs to be removed, providing a roughly horizontal support surface, making it convenient for users to pull out the second filter box 21102 smoothly. The operation is simple and convenient, improving the efficiency of users cleaning the objects to be cleaned when using the base station.

[0168] In some embodiments, the fourth baffle is a single-layer panel structure or a double-layer panel structure. The double-layer panel structure offers better structural strength and durability, and is also more aesthetically pleasing. The fourth baffle can be transparent or opaque. A transparent fourth baffle allows the user to easily observe the process of waste falling from the first filter box into the second filter box, as well as the waste storage status within the second filter box. The following explanation uses a double-layer panel structure as an example.

[0169] In some embodiments, referring to FIG11, the fourth baffle may include an inner baffle 2000212 and an outer baffle 2000211. The outer baffle and the inner baffle can be fixed together by means of screws, snap-fits, etc. Reinforcing ribs may be provided on the outer baffle and the inner baffle to enhance the strength of the fourth baffle. The side of the fourth baffle facing the ninth opening is also provided with a clearance space 2056a, which can play a clearance role when the fourth baffle rotates, ensuring that the fourth baffle can smoothly open or close the ninth opening. In some embodiments, the fourth baffle also includes a second groove 2000212a. After the fourth baffle is pressed and the locking mechanism is released from locking the fourth baffle, the second groove can accommodate the user's fingers, and the user can hold the fourth baffle in the second groove and fully open the fourth baffle.

[0170] In some embodiments, as shown in Figures 2 to 5, the connecting mechanisms are distributed away from or offset from the third receiving cavity. For example, there are two connecting mechanisms, symmetrically arranged on the fourth baffle to support the fourth baffle. The two connecting mechanisms are also arranged on both sides of the third receiving cavity, for example, the two connecting mechanisms are respectively arranged in the fourth receiving cavity and the seventh receiving cavity 2057.

[0171] In some embodiments, as shown in Figures 2 to 7, the connecting mechanism includes a first bracket 21603 and a first connecting rod 21604. The first bracket is disposed on the base station body and has a first slide rail 216031 extending generally horizontally, having a first end 21603a and a second end 21603b. The first end is closer to the ninth opening than the second end. One end of the first connecting rod is rotatably connected to a fourth baffle, and the other end has a second sliding portion 216041 intersecting the first connecting rod. The second sliding portion is slidably disposed within the first slide rail. In the closed state, the second sliding portion abuts against or approaches the second end within the first slide rail. In the open state, the second sliding portion abuts against or approaches the first end within the first slide rail. The first and second ends of the first slide rail can restrict the sliding of the second sliding portion.

[0172] The first slide can be a groove or a hole, etc. In one embodiment, when the first slide is a groove, a first protruding edge 21603c is provided around the first slide, and a fourth reinforcing rib 21603d is provided between the first protruding edge and the outer edge of the first bracket. The fourth reinforcing rib can support the first protruding edge and enhance the strength of the first bracket.

[0173] In some embodiments, the connecting mechanism further includes a first base 21602. One end of the first connecting rod is rotatably connected to the first base, and the other end is provided with a second sliding portion. The first base is fixed to the fourth baffle by screws or other fixing methods. Specifically, the inner baffle 2000212 has a third groove 2000212b, an opening within the third groove, the first base being confined within the third groove, and a first protrusion 216021 of the first base protruding from the opening of the inner baffle. Further, the first protrusion 216021 includes a first segment 21602a and a second segment 21602b, the first segment being arc-shaped and the second segment being sloped or inclined. When the fourth baffle is closed, the first segment can accommodate one end of the first connecting rod. When the fourth baffle is open, the second segment can avoid the end of the first connecting rod, preventing obstruction of the first connecting rod's rotation during the opening of the fourth baffle. The end of the first connecting rod is inserted into the first protrusion and rotatably disposed within the first protrusion via a fixed shaft 21605.

[0174] In some embodiments, the connecting mechanism further includes a damping assembly for reducing the sliding speed of the second sliding portion within the first slide rail. The damping assembly includes a damping element 21606 and at least one first elastic element 21607. The damping element is disposed on the second sliding portion and located outside the side of the first slide rail. One end of the first elastic element is connected to the damping element, and the other end is connected to the second sliding portion. The first elastic element generates a preload force on the damping element, forcing the damping element to abut against the side of the first slide rail. When the second sliding portion slides within the first slide rail, the damping element slides along with the second sliding portion and forms sliding friction with the side of the first slide rail. The damping assembly ensures that the fourth baffle rotates slowly from the closed state to the open state, preventing the fourth baffle from opening too quickly. The connection can be either abutting or achieved through other means.

[0175] Furthermore, in some embodiments, the damping element is fitted over the second sliding portion. The damping assembly also includes a limiting element 21608, which is fixed to the second sliding portion. A first elastic element is located between the limiting element and the damping element. The other end of the first elastic element is connected to the limiting element. The connection can be either abutting against each other or through other means.

[0176] In a specific example, the limiting member includes a fastening part 216081 and a limiting part 216082. The fastening part is threaded onto the second sliding part, and the limiting part is fixed outside the fastening part and extends outward. A first elastic member is located between the limiting part and the damping member.

[0177] The second filter box is retractable within the third receiving cavity. To facilitate the retraction of the second filter box, as shown in Figures 18 to 21, in some embodiments, the base station further includes at least one auxiliary roller 2000213, which is rotatably protruding from the inner wall of the fourth baffle. When the fourth baffle is in the open state, during the retraction of the second filter box from the third receiving cavity, the auxiliary roller generates rolling friction with the bottom of the second filter box. The rotation of the auxiliary roller is driven by the frictional force of the sliding second filter box, and is a passive rotation, requiring no dedicated drive component to rotate the auxiliary roller.

[0178] In a specific example, to facilitate the pulling out of the second filter box 21102, at least one auxiliary roller 2000213 is provided on the inner wall of the fourth baffle 200021. At least one mounting platform is also provided on the inner wall of the fourth baffle, and the auxiliary roller is rotatably fixed to the mounting platform 2000215 via a mounting rod 2000214. The top of the auxiliary roller is higher than the top of the mounting platform, and the bottom of the auxiliary roller is higher than the top of the inner wall of the fourth baffle. When the fourth baffle 200021 is in the open state, the auxiliary roller 2000213 is located on the support surface. The auxiliary roller can convert the sliding friction of the second filter box 21102 during the pulling process into rolling friction, making the pulling process smoother and easier. Simultaneously, the auxiliary roller can also provide additional support and guidance for the extraction of the second filter box when the fourth baffle is open, making the extraction of the second filter box easier and smoother.

[0179] In some embodiments, as shown in FIG2 and with reference to FIGS. 3, 11 and 12, the fourth baffle is connected to the base station body via a rotating connector 21601. The rotating connector includes at least a first arcuate segment and a first horizontal segment extending substantially horizontally. The first arcuate segment is connected to the first horizontal segment and is curved relative to the first horizontal segment. The first arcuate segment is fixedly connected to the fourth baffle, and the first horizontal segment is rotatably connected to the base station body.

[0180] One end of the rotating connector 21601 is rotatably mounted on the base station body via a rotating shaft 216011, and the other end is mounted on the fourth baffle via a fixing part 216012. The through hole in the fixing part 216012 corresponds to the hollow post in the fourth groove 2000212e on the inner baffle. A screw passes through the through hole and the hollow post, thereby fixing the fixing part to the inner baffle, achieving a fixed connection between the rotating connector and the fourth baffle.

[0181] In one specific example, the rotating connector 21601 includes a first arc-shaped segment 21601a and a first horizontal segment 21601b extending generally horizontally. One end of the first horizontal segment is rotatably mounted on the base station body, and the other end is connected to one end of the first arc-shaped segment. The other end of the first arc-shaped segment is provided with a fixing part, which fixes the first arc-shaped segment to the fourth baffle. When the fourth baffle is in the open state, the first horizontal segment overlaps the bottom surface of the ninth opening, and the top surface of the first horizontal segment is slightly higher than the bottom surface of the ninth opening.

[0182] In some embodiments, as shown in FIG12, the rotating connector further includes a second arc-shaped segment, one end of which is connected to the first horizontal segment, and the other end is rotatably connected to the base station body. When the fourth baffle opens the ninth opening, the top surface of the first horizontal segment is approximately flush with the bottom surface of the ninth opening.

[0183] In a specific example, the rotating connector includes a first arc-shaped segment 21601a, a first horizontally extending segment 21601b, and a second arc-shaped segment 21601c. One end of the second arc-shaped segment is rotatably mounted on the base station body, and the other end is connected to one end of the first horizontal segment. The other end of the first horizontal segment is connected to one end of the first arc-shaped segment, and the other end of the first arc-shaped segment is provided with a fixing part, which fixes the first arc-shaped segment to the fourth baffle. A third step 20003 is provided at the position corresponding to the rotating connector on the base station body, and the third step surface is lower than the bottom surface of the ninth opening. When the fourth baffle is in the open state, the first horizontal segment overlaps the third step surface, and the top surface of the first horizontal segment is approximately flush with the bottom surface of the ninth opening, which can prevent the rotating connector from hindering the movement of the second filter box during the pulling process of the second filter box. The second arc-shaped segment is used to compensate for the height difference between the rotating shaft and the third step surface.

[0184] In some embodiments, when the fourth baffle opens the ninth opening, the bottom surface of the ninth opening is substantially flush with the top surface of the fourth baffle. Alternatively, the bottom surface of the ninth opening is higher than the top surface of the fourth baffle.

[0185] As shown in Figures 29 and 30, in some embodiments, the base station further includes a locking mechanism 2070. When the fourth baffle closes the ninth opening, the locking mechanism locks the fourth baffle to the base station body, and the fourth baffle remains closed at the ninth opening. The locking mechanism can release the fourth baffle by pressing it at least once.

[0186] Further, referring to Figures 29 and 30, in some embodiments, the locking mechanism 2070 includes a second slider 2071, a first connector 2072, a second connector 2073, and at least one second elastic member (not shown in the figures). The second slider is slidably disposed on the base station body. The first connector is disposed on the second slider. The second connector is disposed on the fourth baffle. The first connector and the second connector are magnetically connected. At least one second elastic member is disposed on the second slider.

[0187] Specifically, pressing the fourth baffle towards the third receiving cavity causes the second connecting member to push the first connecting member inward, thereby moving the second sliding member inward and forcing the second elastic member to deform and store energy. Releasing the pressure on the fourth baffle releases the stored energy from the second elastic member, driving the second sliding member to move outward from the third receiving cavity, causing the first connecting member to push the second connecting member outward, forcing the fourth baffle to rotate away from the ninth opening, thereby opening at least a portion of the ninth opening.

[0188] In one specific example, the first connector includes at least two members, which are disposed on the second slider and located on opposite sides of the second slider. The two first connectors and the second connector are magnetically connected. In other embodiments, the first connectors may be separately disposed from the second slider. The first connectors and the second connector are magnetically connected.

[0189] One of the first and second connecting parts is a magnetic component, and the other is a metal component that can be attracted by the magnetic component. Alternatively, both the first and second connecting parts can be magnets, with opposite polarities at their closest points. For example, one of the first and second connecting parts is a magnet, and the other is iron. The second elastic component can be a spring, etc.

[0190] After pressing the fourth baffle to release the locking mechanism from locking the fourth baffle, the user places their hand in the second groove of the fourth baffle and applies force toward the outside of the third receiving cavity to fully open the fourth baffle.

[0191] In other embodiments, the locking mechanism consists of a first connector and a second connector, which are magnetically connected to lock the fourth baffle onto the base station body, keeping the fourth baffle closed at the ninth opening. A third handle (not shown in the figure) may also be provided on the outer wall of the fourth baffle 200021. The user pulls the third handle toward the outside of the third receiving cavity to release the locking mechanism from the fourth baffle, after which the fourth baffle can open the ninth opening 2056 under its own gravity.

[0192] As shown in Figure 11, in some embodiments, the base station body further includes a drainage assembly, which includes at least one first drain outlet and at least one drainage component. The drainage component has a drainage channel 2080 for draining liquid from the base station body. The first drain outlet 2120 is located at the bottom of the third receiving cavity. Preferably, the first drain outlet is located at the bottommost position of the bottom of the third receiving cavity. The first drain outlet communicates with the drainage channel. Further, in one embodiment, the drainage channel is located below the first drain outlet, and one end of the drainage channel communicates with the first drain outlet. The drainage channel extends from the first drain outlet outwards from the base station body, such that the other end of the drainage channel is exposed on the side of the base station body or extends beyond the side of the base station body.

[0193] In some embodiments, the bottom of the third receiving cavity includes at least one guide surface 20541, which slopes downward from its top toward the first drain outlet to guide liquid on the guide surface to the first drain outlet. By providing the guide surface, liquid can be quickly guided to the first drain outlet and then discharged outside the base station through the drainage channel. Further, in one embodiment, each side of the third receiving cavity corresponds to at least one guide surface, and adjacent guide surfaces are smoothly transitioned together.

[0194] In some embodiments, at least one support protrusion 20542 is provided on the bottom of the third receiving cavity. When the second filter box is located within the base station body, the bottom of the second filter box abuts against the support protrusion, thereby forming a gap between the bottom of the second filter box and the bottom of the third receiving cavity. The liquid filtered by the second filter box enters the gap and is then discharged from the third receiving cavity through the first drain port. Simultaneously, when the weight of the object to be cleaned inside the second filter box is too large, the support protrusion can support the second filter box and prevent it from deforming.

[0195] In some embodiments, the base station further includes a first nozzle 2173 for spraying water into the first filter box to clean the debris inside the first filter box.

[0196] The base station disclosed herein can be used on land, for example, by placing it on the bank of a pool or on the ground. In this case, the base station is in the air, and the pool robot can automatically get out of the pool and walk onto the base station. For example, the base station also includes a support component, one end of which is attached to the base station body, and the other end extending below the surface of the water in the pool, allowing the pool robot to walk from the pool to the support component and then back to the base station body. Alternatively, the pool robot can be manually carried onto the base station body by a user.

[0197] When the base station is used on shore or on the ground, the first filter box is in the air, and the first nozzle sprays water at least to the side and / or bottom of the first filter box to rinse the side and / or bottom of the first filter box, not only flushing the garbage inside the first filter box out of the first filter box, but also washing away the garbage attached to the side and / or bottom of the first filter box.

[0198] When the base station is placed on the shore or on the ground, the water source for cleaning the first filter box can be municipal water from the user's home. For example, water from a tap. Since municipal water is pumped to the user's tap, the base station may or may not need to have a first water pump. Alternatively, the water source for cleaning the first filter box can be other types of water, such as water from a pool or river. In this embodiment, the base station needs to include at least one first water pump, which draws water from the pool or river to the first nozzle, causing the nozzle to spray water.

[0199] The liquid filtered by the second filter can be discharged into the user's sewer or outdoor lawn; alternatively, it can be discharged into a pool for reuse. Furthermore, the base station also includes a second water pump, which is used to pump the liquid filtered by the second filter out of the base station to accelerate the discharge of the liquid from the base station.

[0200] The base station disclosed herein can also be placed inside a pool or in a placement area connected to the pool. For example, the base station can be placed on a raised platform inside the pool. For example, the raised platform can be a sun deck or steps within the pool, wherein the sun deck and steps can be separated in the pool, or the sun deck can serve as a step surface of the steps. Alternatively, a recessed placement area can be provided on the pool bank, communicating with the pool through an opening in the pool wall, and the base station can be installed in this placement area. Alternatively, the base station can be installed on the pool wall; or on the bottom of the pool; or it can be placed in other locations within the pool. When the base station is installed inside the pool or in a placement area, a pool robot can automatically walk back to the base station body from the pool; or the pool robot can be manually carried to the base station body by a user.

[0201] The base station also includes a drainage channel for discharging the liquid filtered by the second filter box outside the base station; one end of the drainage channel connects to the third receiving cavity, and the other end serves as the final drain outlet. In scenarios where the base station is placed in a pool or placement area, when the pool robot is stationary on the base station body, if the final drain outlet is at least partially or completely below the first liquid level in the pool, the base station also includes at least one second water pump for pumping the liquid filtered by the second filter box out of the base station. If the final drain outlet is above the first liquid level in the pool, the base station may or may not have a second water pump.

[0202] If the base station is placed in a pool or within a designated area, when the pool robot is stationary on the base station, if the first liquid level in the pool is lower than or roughly level with the fourth opening of the base station, the first filter box is located above the fourth opening and is therefore in the air. Alternatively, if the first liquid level in the pool is lower than the bottom of the first filter box, the first filter box is also in the air. The first nozzle sprays liquid onto the first filter box to clean it. The cleaning effect of the first nozzle on the first filter box is roughly the same as if the base station were on land or ground. In other words, the first nozzle sprays water onto the first filter box located in the air to clean the debris inside and adhering to the inner wall of the first filter box.

[0203] The main body of the pool robot is provided with at least one first water outlet 1041. At least part of the first water outlet is located on the top of the main body. When the pool robot cleans the liquid in the pool, the liquid filtered by the first filter box is discharged out of the pool robot through the first water outlet.

[0204] In scenarios where the base station is placed in a pool or within a designated area, when the pool robot is stationary on the base station, if the first liquid level in the pool is between the bottom of the first filter box and the first outlet, at least a portion of the side of the first filter box is positioned below the first liquid level, creating a second liquid level within the first filter box. This second liquid level can be higher, lower, or equal to the first liquid level. For example, when the pool robot is stationary on the base station, before the first nozzle and second water pump are running, the first liquid level in the pool is between the bottom of the first filter box and the first outlet; or, when at least one of the first nozzle and second water pump is running, the first liquid level in the pool is between the bottom of the first filter box and the first outlet.

[0205] For example, for ease of description, the side portion of the first filter box located below the second liquid surface is referred to as the first side portion, and the side portion of the first filter box located above the second liquid surface is referred to as the second side portion. Since the first side portion is located below the second liquid surface and the second side portion is located above the second liquid surface, that is, the second side portion is in the air environment, when the first nozzle sprays water onto the first side portion and the second side portion, the first impact force of the water sprayed onto the first side portion is greatly reduced, while the second impact force of the water sprayed onto the second side portion is not reduced. The first impact force is less than the second impact force. Therefore, the water sprayed by the first nozzle can clean the garbage attached to the second side portion, but cannot clean the garbage attached to the first side portion.

[0206] Therefore, in order to clean the debris attached to the first side of the first filter box, in this embodiment, the liquid in the first filter box is continuously drawn into the second filter box by operating the aforementioned second water pump (e.g., turning it on or increasing the operating parameters). The liquid is then filtered by the second filter box, making the outflow of water from the first filter box greater than the flow rate of liquid sprayed from the first nozzle into the first filter box (i.e., the inflow of water into the first filter box); or the drainage volume of the second water pump per unit time is greater than the spray volume of the first nozzle per unit time, causing the second liquid level in the first filter box to drop. This keeps the side of the first filter box continuously exposed above the second liquid level, i.e., in the air environment, thereby reducing the proportion of the first side on the side of the first filter box. This allows the water flow sprayed by the first nozzle to clean the second side above the second liquid level.

[0207] For example, in some embodiments, by operating the second water pump, the second liquid level in the first filter box is lowered to or below the third opening of the first filter box. This means that most of the sides of the first filter box are above the second liquid level, allowing the water jet from the first nozzle to clean most of the sides of the first filter box. For instance, if the second water pump is off before adjusting the second liquid level, the controller turns it on when adjustment is needed. Alternatively, if the second water pump is running before adjusting the second liquid level, the controller increases its operating parameters when adjustment is required. Furthermore, the base station also includes a sensor to detect the second liquid level, allowing the controller to control the second water pump to start or adjust its operating parameters based on the sensor's detection signal.

[0208] Alternatively, in some embodiments, the operation of the second water pump adjusts the height of the second liquid level in the first filter box to a preset height; once the second liquid level reaches the preset height, it is kept at the preset height to facilitate the first nozzle spraying liquid to clean the side of the first filter box.

[0209] For example, a first filter screen 1055 is provided on the side of the first filter box to form a first filter surface. Debris easily adheres to the first filter screen, so when the first nozzle cleans the side of the first filter box, it primarily cleans the first filter screen. The height of the second liquid level is adjusted by operating the second water pump to ensure that the first filter screen is positioned above the second liquid level, i.e., in the air environment. Alternatively, in some embodiments, a first filter screen may or may not be provided at the bottom of the first filter box. If a first filter screen is provided at the bottom of the first filter box, the second liquid level is adjusted by operating the second water pump to ensure that the first filter screen at the bottom of the first filter box is also positioned above the second liquid level, facilitating the cleaning of debris adhering to the first filter screen when the first nozzle sprays liquid onto the bottom of the first filter box.

[0210] In other words, if most or all of the first filter screen is below the second liquid surface, the liquid in the first filter box needs to be sucked away by the operation of the second water pump, so that most of the first filter screen is above the second liquid surface, that is, the first filter screen is in the air environment, which makes it easier for the first nozzle to spray liquid onto the first filter screen to wash away the garbage attached to the first filter screen.

[0211] Furthermore, if the base station is placed in a pool or designated area, when the pool robot is stationary on the base station, if the first liquid level in the pool is higher than the first outlet, when the second water pump operates to adjust the height of the second liquid level, the liquid in the pool will flow back through the first outlet into the first filter box. This increases the amount of water entering the first filter box, requiring the water pump to operate at higher parameters to lower the second liquid level so that most of the first filter screen is above the second liquid level. Therefore, in actual use, it is best to keep the first liquid level below the first outlet; however, it can also be above the first outlet. Alternatively, if the base station is placed in a pool or designated area, the second liquid level in the first filter box can be adjusted without using the second water pump; the first nozzle can also spray water onto the sides and bottom of the first filter box to clean it, although the cleaning effect is relatively weaker, it can still clean most of the debris inside the first filter box.

[0212] In some embodiments, if the base station is placed in a pool or a designated area, the pool robot is charged wirelessly.

[0213] In some embodiments, if the base station is placed in a pool or within a designated area, the water source for cleaning the first filter box can be liquid from the pool. In this case, the base station also includes the aforementioned first water pump to pump the liquid from the pool to the first nozzle. Alternatively, the water source for cleaning the first filter box can be municipal water from the user's home, such as tap water. In this embodiment, the liquid filtered by the second filter box can be discharged back into the pool for reuse; alternatively, it can be pumped into the user's sewer or onto the user's outdoor lawn by the operation of the second water pump.

[0214] Furthermore, regardless of whether the base station is used on land or on the ground, or placed in a pool or designated area, the base station also includes a pressurization component to ensure that the water jet from the first nozzle is high-pressure. The pressurization component can be located in the waterway between the clean water source and the first nozzle. For example, the pressurization component includes, but is not limited to, a booster pump, a water hammer pump, a pressure tank, a mechanical pressurization device, an elevated water tank, etc., or the water pressure of the jet from the first nozzle can be increased by reducing the size of the nozzle on the first nozzle.

Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
