Description

[0001] This disclosure claims priority to PCT application No. PCT / CN2025 / 126025, filed on September 30, 2025, entitled "A base station, a cleaning system, a cleaning system control method and a pool robot", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of cleaning equipment technology, and more particularly to a cleaning system. Background Technology 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.

[0004] 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 acts as a transfer station or 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

[0005] This disclosure aims to solve the above-mentioned problems and discloses a cleaning system that can automatically filter garbage inside the base station and discharge liquid to the outside of the base station in a timely manner. While reducing the space occupied by garbage inside the base station, it avoids secondary pollution through solid-liquid separation and prevents garbage inside the base station from emitting odors. At the same time, it discloses a second cleaning component that can automatically spray the first filter box, achieving the effect of automatic cleaning of the first filter box and centralized collection of dirt. Moreover, the shielding component can effectively prevent the splashing of cleaning water, effectively improving the automation, hygiene and ease of use of the system.

[0006] This disclosure provides a cleaning system comprising a base station and a pool robot; wherein the pool robot comprises: a first body; a first filter box, the first filter box being at least partially disposed within the first body; and a fourth inlet disposed on the first body; wherein the base station comprises: a base station body; a second filter box, at least for receiving debris from the first filter box; and a second cleaning component, including at least one first nozzle; when the pool robot stops on the base station body, the first nozzle extends into the first body through the fourth inlet for spraying liquid into the first filter box; and exits the first body through the fourth inlet.

[0007] This disclosure involves setting up a second filter box to receive the waste in the first filter box, thereby automatically transferring the waste in the first filter box to the second filter box; in addition, the waste received by the second filter box is further filtered, and the filtered liquid is discharged outside the base station in a timely manner, which can prevent the waste from smelling bad in the second filter box.

[0008] This disclosure utilizes a collaborative design between a base station and a pool robot. By using the relative movement between the first nozzle and the pool robot, the first filter box is automatically cleaned without requiring manual disassembly and cleaning by the user. This achieves automatic and comprehensive cleaning of the first filter box, improving the user experience.

[0009] In addition, the second cleaning component also includes a shielding component. When the first nozzle is inserted into the first filter box, the shielding component can prevent the liquid sprayed by the first nozzle from flowing out of the main body from the fourth inlet. The shielding component can effectively prevent the cleaning water from splashing out and improve the user experience.

Detailed Implementation

[0013] 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.

[0014] like Figures 1 to 5 As shown, an exemplary embodiment of this disclosure provides a cleaning system. The cleaning system includes a pool robot 1000 and a base station 2000, wherein the base station is at least used to clean the pool robot's first filter cartridge 1051, so that debris in the first filter cartridge is transferred from the pool robot or temporarily stored in the base station. Further, as... Figure 1 and Figure 2 As shown, in some embodiments, the base station includes at least a base station body 20001 and a second filter box 21102, at least a portion of which is located within the base station body. The second filter box is used to receive and further filter debris from the first filter box.

[0015] The Pool Robot 1000 is the main working unit of the cleaning system, responsible for performing cleaning tasks in the pool.

[0016] Base station 2000 is the support center of the cleaning system, providing services such as docking, cleaning, and charging for the pool robot. The base station body 20001 constitutes the main support structure of the base station, and its top is equipped with a resting surface 200018 for the pool robot to dock.

[0017] It should be noted that the base station in this example can be used on land. For example, the base station can be placed on the bank of a pool or on the ground. In this case, the base station is in the air environment, 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 of which extends below the surface of the pool water, 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 the user.

[0018] When the base station is used on shore or on the ground, the first filter box is in the air, and the first nozzle 2173 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.

[0019] 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; or 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 also includes at least one first water pump, which pumps water from the pool or river to the first nozzle, causing the first nozzle to spray water.

[0020] 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.

[0021] The base station in this embodiment 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, where the sun deck and steps can be separated in the pool, or the sun deck can serve as a step surface of a step. 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, the 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 the user.

[0022] 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.

[0023] 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.

[0024] The first 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 first 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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 maintained at the preset height to facilitate the first nozzle spraying liquid to clean the side of the first filter box.

[0030] For example, a first filter screen 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 second water pump adjusts the height of the second liquid level 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 water pump adjusts the second liquid level 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.

[0031] 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, so that the first nozzle can spray liquid onto the first filter screen to wash away the garbage attached to the first filter screen.

[0032] 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.

[0033] 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 a high-speed water flow from the first nozzle. 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 it can increase the water flow velocity by reducing the diameter of the pipe adjacent to and connected to the first nozzle and / or reducing the orifice diameter (e.g., the outlet) at the water flow outlet.

[0034] In some embodiments, the pool robot can dock with the base station in the following ways: the pool robot docks with the base station underwater or on the water. The positional relationship between the pool robot and the base station when docking can be arranged horizontally or vertically. That is, when the pool robot is on the base station, it can lie on the base station body or carrier in a roughly vertical posture; or, it can be located on the base station body or carrier in a roughly horizontal posture.

[0035] For example, in some embodiments, the base station is located on the water, and at least a portion of the carrier is located underwater. When the base station docks with the pool robot, both the carrier and the pool robot are in a generally vertical position. At this time, the pool robot lies on the carrier to achieve docking between the base station and the pool robot, and the pool robot is located on the left or right side of the carrier. Alternatively, in another embodiment, the base station is located underwater, and when the base station docks with the pool robot, both the base station and the pool robot are in a generally horizontal position, and the pool robot is located above the base station body. Alternatively, in other embodiments, the base station is located on the water, and when the base station docks with the pool robot, both the base station and the pool robot are in a generally horizontal position, and the pool robot is located above the base station body.

[0036] 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.

[0037] In some embodiments, such as Figure 1 , Figure 2 and Figure 18 As shown, the pool robot includes a first body 1001, at least one liquid inlet, at least one first filter box 1051, at least one liquid outlet, and at least one suction assembly. The liquid inlet is used to allow liquid from the pool to enter the pool robot body 1001, enabling the robot to clean at least one of the pool bottom, pool walls, waterline, and water surface. At least a portion of the first filter box is located within the first body, and the first filter box is used to filter the liquid entering it. The liquid outlet is used to discharge the filtered liquid from the first body. The suction assembly generates suction force to guide the liquid flow. The first filter box filters dust-laden water, leaving debris in the water within it. Under the action of the suction assembly, dust-laden water from the pool is drawn into the first filter box through the liquid inlet, filtered, and debris remains in the first filter box. The filtered liquid, after passing through the suction assembly, is finally discharged from the first body through the liquid outlet.

[0038] In some embodiments, such as Figure 2 and 25 As shown, the liquid inlet section includes at least a first inlet 1031, the liquid outlet section includes at least one first outlet 1041, and the suction assembly includes a main water pump 1061. The first inlet 1031, the first filter box 1051, the main water pump 1061, and the first outlet 1041 are sequentially fluidly connected to form a first water path for cleaning the bottom wall, side wall, or waterline of the pool. For example, in some embodiments, there is one first outlet. Alternatively, in other embodiments, there are multiple first outlets. For example, there are two, three, or more first outlets.

[0039] In other embodiments, such as Figure 2 , Figures 24 to 28 As shown, the liquid inlet section includes at least a second water inlet 1032, the liquid outlet section includes at least a first water outlet 1041, and the suction assembly includes a main water pump 1061; the second water inlet 1032, the first filter box 1051, the main water pump 1061 and the first water outlet 1041 are connected in sequence to form a second water channel, which is used to clean the water surface and water line, that is, the second water inlet is at least used to allow the garbage on the liquid surface to enter the first filter box.

[0040] For the first inlet, in some embodiments, such as Figure 1 As shown, the first water inlet 1031 is located at the bottom of the first main body 1001; correspondingly, as... Figure 24As shown, the first filter box is provided with at least one first inlet 10511a, which is adjacent to and communicates with the first water inlet 1031, so that the liquid in the pool enters the first filter box 1051 through the first water inlet 1031 for filtration. Further, in some embodiments, the first inlet is located at the bottom of the first filter box.

[0041] In other embodiments, the second inlet 1032 is located on the side of the first body 1001, correspondingly, such as Figure 19 As shown, the first filter box is provided with at least one second inlet 10511b, which is adjacent to and communicates with the second water inlet 1032, so that the liquid on the surface of the pool water enters the first filter box 1051 through the second water inlet 1032 for filtration. Further, in some embodiments, the second inlet is located on the side of the first filter box.

[0042] In some embodiments, a first baffle 10511c is provided at the first inlet 1031 or the first inlet 10511a. A second baffle 10511d is provided at the second inlet 10511b. When the pool robot is cleaning the water surface, the first baffle is in a closed state to prevent liquid in the pool from entering the first filter box through the first inlet 1031, and the second baffle is in an open state to allow liquid to enter the first filter box through the second inlet and the second inlet. When the pool robot is cleaning the pool bottom or pool wall, the second baffle is in a closed state to prevent liquid from entering the first filter box through the second inlet, and the first baffle is in an open state to allow liquid to enter the first filter box through the first inlet 1031. That is, when cleaning the water surface, the first baffle is in a closed state and the second baffle is in an open state; when cleaning the pool wall or pool bottom, the first baffle is in an open state and the second baffle is in a closed state.

[0043] In some embodiments, a second baffle is rotatably disposed on the first body to open or close the second water inlet. For example, the second baffle opens the second water inlet by rotating outward toward the first body; the second baffle closes the second water inlet by rotating from the outside of the first body toward the second water inlet. Further, the second baffle is rotatably disposed on the side of the first body. Further, in some embodiments, after the second baffle opens the second water inlet, the first nozzle extends through the second water inlet and the second inlet into or out of the first filter box.

[0044] In some embodiments, in order to discharge the waste from the first filter box, such as Figure 1 and Figure 24As shown, the first filter box includes at least one third opening 10531; and a first bottom cover 1054, which can open or close the third opening. At least a portion of the third opening is located on the bottom of the first filter box. When the pool robot stops on the base station body, after the first bottom cover opens the third opening, the third opening can communicate with the third inlet of the second filter box, allowing waste and liquid in the first filter box to be discharged from the third opening and fall into the second filter box through the third inlet.

[0045] In some embodiments, the first filter box 1051 includes a first frame 1053, the aforementioned first bottom cover, and a first filter screen 1055; at least a portion of the third opening is disposed on the bottom of the first frame; or, the bottom opening of the first frame serves as the third opening; the first filter screen is disposed on at least one side wall of the first frame to form a filter surface for filtering liquid entering the first filter box; the first bottom cover is movably disposed on the first frame to open or close the third opening.

[0046] In some embodiments, to facilitate the placement and removal of the first filter cartridge within the pool robot, such as Figure 5 As shown, the pool robot also includes a loading / unloading port 1017 and a first cover 1018. At least a portion of the loading / unloading port is located on the top of the first main body and communicates with the first receiving cavity. The first cover is movably located at the loading / unloading port to open or close it. The loading / unloading port is used for a user to place the first filter box into the first receiving cavity or remove the first filter box from the first receiving cavity.

[0047] In some embodiments, such as Figure 5 As shown, the first filter box also includes an eleventh opening 10532, at least a portion of which is located on the top of the first filter box; the eleventh opening is connected to the inlet / outlet, making it convenient for the user to empty the waste in the first filter box through the eleventh opening.

[0048] In some embodiments, such as Figure 1 As shown, the first main body also includes a first dust bin 1052, which is disposed within the first main body, and the inner cavity of the first dust bin serves as a first receiving cavity. In some embodiments, the loading and unloading port is located on the top of the first dust bin, the first filter box is disposed within the first dust bin, and a first cover 1018 is provided above the first dust bin. The first cover is disposed on the first main body and is used to cover the loading and unloading port of the first dust bin. Opening the first dust bin cover 1018 exposes the first filter box 1051, thereby facilitating the user to remove or put back the first filter box 1051 from the first receiving cavity.

[0049] In some embodiments, the pool robot includes a fourth handle (not shown), which the user holds to easily lift the pool robot out of the pool and bring it out of the water; or, the user can carry the pool robot on the shore. For example, the fourth handle is located on the front of the first body.

[0050] In some embodiments, the base station further includes a second cleaning component, which includes at least one first nozzle 2173. The first nozzle can clean the first filter box by spraying liquid onto it. When the pool robot stops on the resting surface of the base station body, the liquid is sprayed through the first nozzle to clean the first filter box, causing debris in the first filter box to fall into the second filter box, thereby transferring the debris from the first filter box to the second filter box.

[0051] Specifically, the first nozzle is installed on the base station body. When the pool robot stops on the base station body, the first nozzle is used to spray liquid onto the first filter box to rinse the garbage inside the first filter box and the garbage attached to the wall of the first filter box, thereby cleaning the garbage inside the first filter box.

[0052] In some embodiments, the liquid inlet component includes at least one second liquid inlet assembly (not shown) in fluid communication with the first nozzle and capable of fluid communication with the water supply component. In one embodiment, a second shielding cover may be disposed on the second liquid inlet assembly.

[0053] Furthermore, in some embodiments, the liquid inlet component further includes at least one first liquid inlet assembly (not shown in the figure), one end of which is rotatably connected to one end of a second liquid inlet assembly, and the other end of which is connected to a first nozzle; the other end of the second liquid inlet assembly is used to connect to a water supply component. In one embodiment, a second shielding cover is disposed on the first liquid inlet assembly and rotates synchronously with the first liquid inlet assembly. When the first nozzle is in the extended position, the first nozzle extends into the pool robot through the fourth inlet of the pool robot to spray liquid into the first filter box, and the second shielding cover is used to shield the fourth inlet.

[0054] In some embodiments, the second shielding cover may be fixedly or detachably mounted on the first liquid inlet assembly or the second liquid inlet assembly.

[0055] In some embodiments, a first nozzle extends into a first filter box, with at least a portion of the first nozzle (e.g., a nozzle) facing a third opening to rinse at least the debris at the bottom of the first filter box and accelerate the discharge of debris from the third opening; or, at least a portion of the first nozzle faces the side of the first filter box to rinse at least the debris on the side of the first filter box; or, at least a portion of the first nozzle faces both the third opening and the side of the first filter box to rinse the first filter box from all directions.

[0056] In some embodiments, such as Figure 9 As shown, the first nozzle includes at least one nozzle 21732, which is connected to and in communication with the liquid inlet component 21731. The nozzle has at least one first spray nozzle 217321, which is used to spray liquid onto the side of the first filter box. Furthermore, the first spray nozzle is a powered spray nozzle, which can drive the first nozzle to rotate relative to the liquid inlet component 21731 while spraying liquid.

[0057] For example, the power nozzle is set with an offset angle, or the water flow is guided to an inclined channel before being sprayed out; when the high-speed water flow is sprayed out from the offset power nozzle, it will generate a reverse thrust on the nozzle. This thrust has a component force in the direction perpendicular to the rotation axis. This component force forms a torque on the rotation center of the nozzle. Under the continuous action of this torque, the nozzle begins to rotate around its axis.

[0058] In some embodiments, the nozzle is provided with at least one second spray nozzle (not shown in the figure), which is used at least to spray liquid onto the bottom of the first filter box. Further, the second spray nozzle is a non-powered spray nozzle.

[0059] Alternatively, in other embodiments, the nozzle is provided with at least one first spray nozzle and at least one second spray nozzle. The first spray nozzle is used to spray liquid onto the side of the first filter box at least, and the second spray nozzle is used to spray liquid onto the bottom of the first filter box at least, so as to clean the first filter box from all directions. Further, the first spray nozzle is a powered spray nozzle, and the second spray nozzle is a non-powered spray nozzle.

[0060] In some embodiments, the liquid sprayed by the first nozzle, i.e., the cleaning water source or cleaning liquid, can be water from a swimming pool, pool, or river; or tap water supplied to a water tank, faucet, or shower head; or cleaning liquid to further remove oil stains, stubborn dirt, etc. from the filter screen; or a mixture of any two or more of the above water sources, for example, a mixture of tap water and cleaning liquid; or a mixture of water from a swimming pool, pool, or river and cleaning liquid.

[0061] In some embodiments, the cleaning water source is provided by a water supply component. For example, when the cleaning water source is liquid in a swimming pool, pond, river, or water tank, the water supply component can be a swimming pool, pond, river, or water tank. In this case, the second cleaning component may also include a first water pump to supply liquid from the swimming pool, pond, river, or water tank to the first spray head. Alternatively, when the cleaning water source is an indoor or outdoor faucet in a user's home or a sprinkler head on a lawn, the water supply component can be a faucet or a sprinkler head. In this case, the second cleaning component may also include a first water pump connected to the faucet or sprinkler head to provide cleaning water to the first spray head. Alternatively, in this case, the second cleaning component does not include a first water pump, and the faucet or sprinkler head directly provides cleaning water to the first spray head.

[0062] The first nozzle 2173 can effectively clean the various walls (including the top wall, side walls, and bottom wall) of the first filter box 1051 by spraying cleaning liquid into the first filter box 1051. Specifically, it can thoroughly break up and wash away algae, leaf fragments, and other dirt adhering to the walls of the first filter box by rinsing with high-speed water flow, or it can spray cleaning liquid to directionally rinse the first filter box, dissolving or washing away the dirt attached to the filter screen and restoring the filtration performance. Through mechanized and precise spraying, the cleaning effect of the first filter box is ensured to be consistent, while reducing the frequency and difficulty of manual maintenance by users. In addition, the automatic rinsing process can be executed automatically on a regular basis, ensuring that the pool robot is in the best condition every time it starts working, thereby maintaining its long-term cleaning efficiency.

[0063] In some embodiments, through the coordinated operation of the pool robot 1000 and the base station 2000, i.e., based on the relative movement of either the first nozzle 2173 or the pool robot 1000, the first nozzle can be aligned with and enter the area where the first filter box 1051 is located, thereby performing efficient automatic cleaning. For example, when the first nozzle is stationary relative to the base station body, the pool robot 1000 can use corresponding actions such as vertical lifting or horizontal movement to allow the first nozzle to at least partially extend into the pool robot to clean the inside of the first filter box. Alternatively, after the pool robot 1000 stops at a designated position on the resting surface, the rotation and / or extension of the first nozzle allows it to at least partially extend into the pool robot to clean the inside of the first filter box.

[0064] In some embodiments, see Figure 1 , Figure 2As shown, the first body 1001 is provided with at least one fourth inlet 1016. The fourth inlet communicates with the first filter box, allowing the first nozzle to extend into or exit the pool robot through the fourth inlet. Since the first nozzle can extend into the first body to spray liquid onto the first filter box, the liquid sprayed by the first nozzle is ensured to reach the first filter box, guaranteeing its cleaning effect. In other words, the fourth inlet 1016 communicates with the interior of the first body 1001, serving as a dedicated channel for the first nozzle 2173 to enter and exit the interior of the first body, ensuring that the nozzle of the first nozzle can accurately reach the cleaning position while minimizing the impact on the robot's original structure and function.

[0065] Alternatively, in some other embodiments, a fourth inlet is provided on the first body, but the first nozzle does not extend into the first body. The first nozzle is located outside the first body, and the first nozzle sprays liquid from outside the first body through the fourth inlet to the first filter box, which can also achieve the cleaning of the first filter box.

[0066] Regarding the first nozzle extending into the first body to spray liquid onto the first filter box, in some embodiments, at least a portion of the first nozzle extends into the first filter box through a fourth inlet to spray liquid onto the first filter box; or, in other embodiments, at least a portion of the first nozzle extends into the relative gap between the first receiving cavity and the outside of the first filter box through a fourth inlet to spray liquid onto the first filter box, i.e., the first nozzle sprays liquid from the outside of the first filter box into the first filter box. In this embodiment, in order for at least a portion of the first nozzle to extend into the relative gap, the size of the relative gap needs to be relatively large, which will increase the size of the first body; furthermore, the liquid in the relative gap needs to be discharged from the first outlet by the main water pump, which requires the main water pump to generate greater suction force, thus increasing the power of the main water pump; while in the embodiment where the first nozzle extends into the first filter box, the size of the relative gap is relatively small, the structure of the pool robot is compact, and the liquid in the relative gap is discharged from the first outlet by the main water pump, requiring less suction force from the main water pump.

[0067] For ease of explanation, the following description will use the example of the first nozzle extending into the first filter box; of course, in any of the embodiments described below, the method of the first nozzle extending into the first filter box can be replaced by the first nozzle extending into the gap between the first receiving cavity and the first filter box to spray liquid to clean the first filter box. For the sake of brevity, this will not be repeated in the following text.

[0068] For the fourth entrance, such as Figure 1 and Figure 2 As shown, the fourth entry point 1016 can be implemented in several ways: For example, in some embodiments, the fourth inlet 1016 can be reused with the second inlet 1032. The second inlet 1032 is itself used for water intake during surface cleaning. When used as the fourth inlet, the first nozzle 2173 can extend into or exit through the second inlet 1032 in a horizontal direction. This reuse design maximizes the use of the existing structure, avoids additional openings, simplifies the manufacturing process, and maintains the structural integrity and sealing performance of the robot housing. For example, the second inlet is located on the front or rear sidewall of the first body.

[0069] For example, in some embodiments, the fourth inlet 1016 can be reused with the existing pick-and-place port 1017. When used as the fourth inlet, the first nozzle 2173 can extend into or retract vertically through the pick-and-place port. This reuse design saves space and avoids additional openings.

[0070] Alternatively, in other embodiments, the fourth inlet 1016 can be reused with the existing first inlet. The first inlet is itself used for water intake during underwater cleaning. When used as the fourth inlet, the first nozzle 2173 can extend into or retract vertically through the first inlet.

[0071] For example, in some embodiments, the fourth inlet 1016 can be a separate opening on the first main body shell, specifically designed for cleaning functions. For example, in some embodiments, the fourth inlet can be independent of the second water inlet and located on the first main body as a pick-up / drop-off port. For example, the second water inlet may be located on the front sidewall of the first main body, and the fourth inlet on the rear sidewall of the first main body; or, the fourth inlet may also be located on the front sidewall of the first main body, but offset from the second water inlet. Alternatively, in some embodiments, the fourth inlet is not located on the bottom of the first main body; or, in other embodiments, the fourth inlet is located on the bottom of the first main body, but is different from the first water inlet. For example, the fourth inlet and the first water inlet are offset from each other on the first main body.

[0072] In order to allow the first nozzle to extend into the first filter box and clean the first filter box, in some embodiments, a twelfth opening 10536 is provided on the first filter box corresponding to the aforementioned fourth inlet (see reference). Figure 30The fourth inlet and the twelfth opening are adjacent or close to each other and are connected. The first nozzle extends into the first filter box through the fourth inlet and the twelfth opening to spray liquid into the first filter box, and exits the first body through the fourth inlet and the twelfth opening. Further, the first nozzle sequentially extends into the first filter box through the fourth inlet and the twelfth opening, and exits the first body sequentially through the twelfth opening and the fourth inlet. For example, when the second inlet is used as the fourth inlet, the second inlet correspondingly serves as the twelfth opening; or, when the inlet / outlet is used as the fourth inlet, the eleventh opening correspondingly serves as the twelfth opening; or, when the first inlet is used as the fourth inlet, the first inlet correspondingly serves as the twelfth opening.

[0073] In some embodiments, the pool robot also includes a baffle movably disposed at a fourth entrance, the baffle being used to open or close the fourth opening.

[0074] In some embodiments, such as Figures 6 to 9 ,as well as Figures 23 to 32 As shown, this embodiment provides two main implementation methods regarding the relative motion between the first nozzle 2173 and the pool robot 1000: First implementation method: The first nozzle is stationary, while the pool robot moves.

[0075] In this mode, the first nozzle 2173 is fixed relative to the base station body 20001. The movement of the pool robot causes the first nozzle to passively pass through the fourth inlet and extend into or exit from the pool robot.

[0076] Regarding the movement of the pool robot, in some embodiments, the pool robot actively moves on the base station body, causing the first nozzle to passively extend into or out of the pool robot through the fourth inlet. In some embodiments, a clean position and a non-clean position (such as a charging position) are defined on the resting surface 200018 of the base station body. As the pool robot moves from a non-clean position to a clean position, the first nozzle passively extends into the first filter box through the fourth inlet; as the pool robot moves from a clean position to a non-clean position, the first nozzle passively exits from the pool robot through the fourth inlet. A clean position is the position where the pool robot rests on the base station body when the liquid sprayed by the first nozzle can clean the first filter box. A non-clean position is the position where the pool robot rests on the base station body where the liquid sprayed by the first nozzle cannot clean the first filter box. Alternatively, the first nozzle cannot extend into the first body through the fourth inlet, and the liquid sprayed by the first nozzle cannot clean the first filter box. Alternatively, any resting position on the base station body other than the clean position can be considered a non-clean position.

[0077] For example, if the second inlet serves as the fourth inlet and is located on the front sidewall of the first body (e.g., the front shell), the first nozzle extends into the first filter box through the second inlet during the pool robot's forward movement from a non-clean position to a clean position. Conversely, the first nozzle retracts from the pool robot during its backward movement from a clean position to a non-clean position. Alternatively, in other embodiments, if the second inlet serves as the fourth inlet and is located on the rear sidewall of the first body (e.g., the rear shell), the first nozzle extends into the first filter box through the second inlet during the pool robot's backward movement from a non-clean position to a clean position; conversely, the first nozzle retracts from the pool robot during its forward movement from a clean position to a non-clean position.

[0078] Furthermore, in some embodiments, when the second water inlet serves as the fourth inlet, the aforementioned second baffle installed on the second water inlet acts as a barrier. When the pool robot is in a non-clean position, the second baffle opens the second water inlet; subsequently, the pool robot moves from the non-clean position to the clean position.

[0079] In other embodiments, when the pick-up and drop-off port is used as the fourth inlet, the first nozzle is stationary relative to the base station body. The first nozzle is passively inserted into the first filter box or removed from the pool robot by moving the pool robot in the height direction of the first body.

[0080] Regarding the movement of the pool robot, in another embodiment, the user manually moves the pool robot so that the first nozzle passively passes through the fourth inlet and extends into or out of the pool robot. In some embodiments, the base station body includes at least a clean position, where the user can directly place the pool robot, or the pool robot can automatically walk to the clean position via a carrier. In another embodiment, the base station body also includes a non-clean position, where the user can directly place the pool robot, or the pool robot can automatically walk to the non-clean position via a carrier. In this embodiment, the user manually pushes or pulls the pool robot from the non-clean position to the clean position.

[0081] Specifically, when the second water inlet is used as the fourth inlet, the user manually pushes or pulls the pool robot to move horizontally along the base station body; when the first water inlet and the pick-up / drop-off port are used as the fourth inlet, the user manually pushes or pulls the pool robot to move vertically along the first body; or, the user manually pushes or pulls the pool robot to move it in other directions so that the pool robot can move from a non-clean position to a clean position.

[0082] Based on this, the structure of the base station 2000 is effectively simplified in this example. The first nozzle 2173 does not require a complex drive mechanism, reducing costs and failure rates, and improving the long-term reliability of the system. Simultaneously, the movement path of the pool robot can be precisely controlled, ensuring accurate nozzle alignment every time. This approach is particularly suitable for applications with compact base station structures and cost-sensitive requirements.

[0083] The second implementation: The first nozzle moves actively, while the pool robot remains stationary. It should be noted that in this case, the pool robot remaining stationary refers to its stationary position after moving to a designated location on the resting surface.

[0084] In this mode, the first nozzle 2173 is movable relative to the base station body 20001. The first nozzle has an extended position and a retracted position, and the first nozzle can switch between the retracted position and the extended position.

[0085] There are several possibilities regarding the retracted and extended positions of the first nozzle. Specifically: In the first scenario: when the first nozzle is in the retracted position, it is located outside the pool robot; when the first nozzle is in the extended position, it extends into the first main body through the fourth inlet. For example, it extends into the gap between the first receiving cavity and the first filter box, or into the first filter box.

[0086] In the second scenario: When the first nozzle is in the retracted position, it is located outside the pool robot and does not interfere with the user lifting the pool robot vertically or the pool robot moving away from the base station's cleaning position. The first nozzle will not collide with the pool robot, and there is no mutual interference between them. When the first nozzle is in the extended position, it extends into the first main body through the fourth inlet. For example, it extends into the gap between the first receiving cavity and the first filter box, or into the first filter box.

[0087] The third scenario: When the first nozzle is in the retracted position, it is located outside the pool robot and does not interfere with the user lifting the pool robot vertically or the pool robot moving away from the base station's cleaning position. The first nozzle will not collide with the pool robot, and there is no mutual interference between the first nozzle and the pool robot. When the first nozzle is in the extended position, it is located outside the pool robot, but the liquid sprayed by the first nozzle can pass through the fourth inlet to clean the first filter box.

[0088] To facilitate the description of the extended and retracted positions of the first nozzle, the following embodiments will use the first case of the extended and retracted positions as examples. In particular, the description will focus on the case where the first nozzle extends into the first filter box in the extended position. Any of the following embodiments is applicable to other cases of extended and retracted positions.

[0089] In some embodiments, the pool robot includes at least a cleaning position. When the pool robot is in the cleaning position, it opens a cover. If the first nozzle is in the retracted position at this time, it needs to move from the retracted position to the extended position. During this movement, the first nozzle gradually extends into the first filter box through the fourth inlet. When the first nozzle reaches the extended position, it is fully inserted into the first filter box. Conversely, when the first filter box is cleaned by the liquid sprayed by the first nozzle, and the first nozzle needs to exit the pool robot, the pool robot remains in the cleaning position, and the first nozzle moves from the extended position to the retracted position. During this movement, the first nozzle gradually exits the pool robot from the fourth inlet until it reaches the retracted position. In this embodiment, by movably mounting the first nozzle on the base station body, the pool robot only needs to be in the cleaning position, and the movement of the first nozzle actively extends into or exits the pool robot into the first filter box. The entire process does not require the pool robot to move on the base station body.

[0090] The active movement of the first nozzle 2173 can be either rotation or extension / retraction, specifically: In some embodiments where the first nozzle is movably mounted on the base station body, the first nozzle is rotatably mounted on the base station body, and the first nozzle can be rotated to extend into the first filter box or retract from the pool robot.

[0091] In some embodiments, the first nozzle rotates from the retracted position to the extended position by a first angle. The first angle can be any angle between 0 and 360 degrees, for example, approximately 10, 15, 30, 45, 53, 60, 75, 80, 85, 90 degrees, etc. Conversely, the first nozzle rotates approximately from the extended position to the retracted position by a second angle, the second angle also being any angle between 0 and 360 degrees. The sum of the first and second angles can be 0 degrees (i.e., the direction of rotation of the first nozzle from the retracted position to the extended position is opposite to the direction of rotation from the extended position to the retracted position), or 180 degrees (i.e., the direction of rotation of the first nozzle from the retracted position to the extended position is the same as the direction of rotation from the extended position to the retracted position); or any other angle between 0 and 360 degrees.

[0092] For example, when the second inlet serves as the fourth inlet, the first nozzle rotates horizontally about the vertical axis to extend through the second inlet into the first filter box or exit the pool robot. Alternatively, in another embodiment, the first nozzle can rotate about other axes (non-vertical axes) to switch between a retracted position and an extended position. The aforementioned first and second angles can be selected as needed and are not specifically limited.

[0093] For example, when the inlet / outlet is used as the fourth inlet, in some embodiments, the first nozzle rotates vertically about a horizontal axis to allow it to extend into or out of the pool robot. Alternatively, the first nozzle can rotate about other axes (non-horizontal axes) to switch between a retracted position and an extended position. The aforementioned first and second angles are selected as needed and are not specifically limited.

[0094] In one embodiment, when the active movement of the first nozzle is rotational, the first nozzle 2173 can be rotatably mounted on the base station body 20001 via a pivot. For example, when the fourth inlet is the second water inlet 1032 on the side, the first nozzle 2173 can rotate around a vertical axis in the horizontal plane, swinging in or out like a "door". When the fourth inlet is the top access port, the first nozzle 2173 can rotate around a horizontal axis in the vertical plane, raising or lowering like a "windshield wiper". The rotational structure is relatively simple, has a large range of motion, and is suitable for installation scenarios requiring a large clearance space.

[0095] In other embodiments, the first nozzle is retractably mounted on the base station body, and the first nozzle extends into or out of the pool robot by retracting movement.

[0096] For example, when the second inlet is used as the fourth inlet, the first nozzle extends through the second inlet into the first filter box or exits the pool robot by horizontal telescopic movement; or, for example, when the pick-up and drop-off port is used as the fourth inlet, the first nozzle extends through the second inlet into the first filter box or exits the pool robot by vertical telescopic movement.

[0097] In some embodiments, when the fourth inlet is provided with the aforementioned baffle, the baffle is used to open or close the fourth opening; the baffle opens the fourth inlet before the first nozzle switches from the retracted position to the extended position; and the baffle closes the fourth inlet after the first nozzle switches from the extended position to the retracted position.

[0098] For example, when the pool robot stops at the cleaning position, the baffle first opens the fourth inlet, and then the first nozzle moves from the retracted position to the extended position, passing through the fourth inlet and extending into the first filter box. Further, for example, when the second inlet serves as the fourth inlet, the aforementioned second baffle acts as a baffle. As another example, when the loading / unloading port serves as the fourth inlet, the pool robot also includes the aforementioned first cover, which is movably mounted on the loading / unloading port for opening or closing the port; the first cover acts as a baffle.

[0099] In one embodiment, when the active movement mode of the first nozzle is telescopic, the first nozzle 2173 can be telescopically mounted on the base station body 20001 via a linear drive mechanism (such as an electric push rod or cylinder). The first nozzle extends directly into or out of the fourth inlet along a straight path. The telescopic mode offers high motion precision, a direct path, and minimal space requirements, making it suitable for scenarios demanding precise motion trajectories. Based on this, this implementation allows the pool robot 1000 to remain stationary during cleaning, simplifying the control logic of the pool robot. It is particularly suitable for designs that combine cleaning and non-cleaning areas, and the movement path of the first nozzle can be more precisely controlled, providing more stable and accurate cleaning performance.

[0100] In some embodiments, to ensure that the baffle does not close accidentally due to vibration or external force during the cleaning of the first filter box, thereby preventing the first nozzle 2173 from extending into or exiting the pool robot from the fourth inlet, the pool robot 1000 further includes at least one limiting component for limiting the baffle to its open position after the baffle opens the fourth inlet.

[0101] For example, in one embodiment, when the second water inlet is used as the fourth inlet, after the baffle plate, i.e. the second baffle, is opened, it can rest against the fourth handle. At this time, the limiting component can be used to make the baffle plate rest stably against the fourth handle, preventing the baffle plate from affecting the movement of the first nozzle, etc.

[0102] In some embodiments, the limiting component may be implemented using a structure such as magnetic attraction, snap-fit, or pin.

[0103] Specifically, in a preferred embodiment, the limiting component employs a magnetic attraction method, comprising a first magnet (not shown in the figure) disposed on the baffle plate and a second magnet (not shown in the figure) disposed at a corresponding position on the first body 1001. For example, the second magnet may be disposed on the fourth handle. When the baffle plate is opened to a specific position, the first magnet and the second magnet attract each other, generating sufficient magnetic force to stably hold the baffle plate in the open state. The magnets can be permanent magnets, or electromagnets can be used to achieve controllable attraction and release, increasing the flexibility of the cleaning system.

[0104] In some embodiments, the second filter box has at least one filter surface for filtering liquids and waste entering therein and retaining the waste inside the second filter box. The second filter box is provided with at least one third inlet 21101, which serves as the entry point for waste into the second filter box.

[0105] like Figure 1As shown, when the pool robot stops at the cleaning position on the base station body, the third inlet connects to the third opening of the first filter box, allowing the debris in the first filter box to enter the second filter box through the third opening and the third inlet. When the pool robot stops on the base station body, the first nozzle sprays liquid into the first filter box. After the first bottom cover of the first filter box opens the third opening, the debris in the first filter box and the liquid sprayed into the first filter box by the first nozzle enter the second filter box through the third opening and the third inlet. The debris remains in the second filter box, and the liquid is filtered by the second filter box and discharged from the base station body. This process collects or temporarily stores the debris from the first filter box into the second filter box, completing the cleaning of the first filter box. No user intervention is required during the cleaning process of the first filter box, achieving automatic cleaning.

[0106] In some embodiments, when the pool robot rests on the base station, it is in a generally horizontal or generally tilted posture. For example, when the pool robot rests on the resting surface of the base station body, it has a generally horizontal or generally tilted posture. In this case, at least a portion of the base station body has a generally horizontal or generally tilted posture.

[0107] In some embodiments, such as Figures 6 to 8 As shown, for the dwelling surface 200018, the dwelling surface refers to the surface on which the pool robot can rest upon returning to the base station body. The dwelling surface can be a horizontal surface, a curved surface, an arc surface, or an inclined surface, etc. For example, in some embodiments, such as... Figures 6 to 8 As shown, the resting surface is the upper or top surface of the base station body.

[0108] Alternatively, in other embodiments, when the pool robot is stationary on the base station, it is in a generally vertical posture. For example, when the pool robot is stationary on the resting surface or support of the base station body, it has a generally vertical posture. For example, in some embodiments, at least a portion of the base station body is located inside the pool for docking with or for the pool robot to rest on. For example, at least a portion of the resting surface or support of the base station body may be located inside the pool and in a generally vertical or generally horizontal posture, and at least a portion of the corresponding first filter box may be located inside the pool and in a generally vertical or generally horizontal posture. Alternatively, in other embodiments, at least a portion of the base station body may be located outside the pool for accommodating or supporting a second filter box. Further, the portion of the base station body outside the pool is in a generally horizontal or generally tilted posture, and the corresponding second filter box is in a generally horizontal or generally tilted posture.

[0109] In some embodiments, when the pool robot is in the cleaning position of the base station body, at least a portion of the first filter box is located above at least a portion of the second filter box, and at least a portion of the third inlet is located below the third opening, so that the inner cavity of the first filter box communicates with the inner cavity of the second filter box, and the debris inside the first filter box can fall into the second filter box through the third inlet under the action of gravity and / or the impact force of the liquid sprayed by the first nozzle. That is, at least a portion of the first filter box or at least a portion of the first frame and at least a portion of the second filter box are vertically distributed in the height direction of the base station body.

[0110] Furthermore, in some other embodiments, when the pool robot is in the cleaning position of the base station body, the first filter box is located directly above the second filter box, and the third opening is located directly above the third inlet, so that the garbage and liquid in the first filter box can quickly fall into the second filter box under the action of gravity.

[0111] Furthermore, in some embodiments, when the pool robot stops at the cleaning position of the base station body, the third inlet is located directly below the third opening, and the area of ​​the third inlet is greater than or equal to the size of the third opening, thereby ensuring that all the debris and liquid in the second filter box can fall into the second filter box under the action of its own gravity and the impact force of the liquid sprayed by the first nozzle. For example, the second projection of the third opening on the horizontal plane falls into the third projection of the third inlet on the horizontal plane. More specifically, in some embodiments, when the pool robot stops at the cleaning position of the base station body and the first bottom cover closes the third opening, the third inlet is located directly below the third opening, and the first filter chamber is located directly above the second filter chamber, and the fourth projection of the first filter box on the horizontal plane falls into the fifth projection of the second filter box on the horizontal plane.

[0112] In other embodiments, at least a portion of the third opening is located above at least a portion of the third inlet, and the base station further includes a power assembly for drawing debris from the first filter box into the second filter box for filtration. In this embodiment, debris from the first filter box can enter the second filter box under its own weight and / or the impact force of the liquid sprayed from the first nozzle, as well as the suction force of the power assembly, to accelerate the falling of debris from the first filter box into the second filter box. For example, the power assembly includes at least one second water pump, which draws debris from the first filter box into the second filter box.

[0113] In other embodiments, when the pool robot stops at the cleaning position of the base station, at least a portion of the first filter box is located above at least a portion of the second filter box, but the third opening and the third inlet are horizontally offset, and the aforementioned second and third projections do not have overlapping areas. Alternatively, in other embodiments, when the pool robot stops at the cleaning position of the base station, the first and second filter boxes are horizontally offset, and the third opening and the third inlet are horizontally offset. In both of these embodiments, the third opening and the third inlet are connected by a pipe, so that the waste in the first filter box enters the second filter box from the third opening, the pipe, and the third inlet. In this embodiment, the base station also includes the aforementioned power component for sucking the waste in the first filter box into the second filter box for filtration.

[0114] In some embodiments, at least a portion of the second filter cartridge is disposed within the base station body, such as... Figure 1 As shown, the base station body includes a third receiving cavity 2054, and at least a portion of the second filter box is disposed within the third receiving cavity. To allow debris from the first filter box to enter the second filter box, as shown... Figure 1 and Figure 2 As shown, the base station body also includes at least one fourth opening 2055. The fourth opening is disposed on the base station body and connects the third receiving cavity to the outside. The third inlet is connected to the fourth opening. When the pool robot stops at the cleaning position of the base station body, at least a portion of the third opening of the first filter box is connected to at least a portion of the fourth opening, and at least a portion of the fourth opening is connected to at least a portion of the third inlet, so that the garbage discharged from the first filter box can enter the second filter box through the fourth opening and the third inlet.

[0115] In some embodiments, the first nozzle sprays liquid into the first filter box through the aforementioned fourth inlet to clean the first filter box. Specifically, when the first nozzle extends into the first filter box and sprays liquid to flush away debris, at least a portion of the first nozzle is directly above at least a portion of the third opening and at least a portion of the fourth opening. The liquid sprayed by the first nozzle pushes the debris in the first filter box towards the third opening; and under the impact of the sprayed liquid, some of the debris in the first filter box is directly flushed into the second filter box, thereby accelerating the entry of debris from the first filter box into the second filter box through the third opening and the third inlet. For example, at least a portion of the first nozzle is directly above the third opening, and the third opening is directly above the third inlet, further accelerating the cleaning of debris in the first filter box.

[0116] To optimize rinsing efficiency and reduce water and time waste, the nozzle 21732 of the first spray head 2173 is carefully positioned. When the first spray head 2173 extends into the first filter box 1051 for cleaning, the projection of the nozzle 21732 on the horizontal plane is preferably located within the projection range of the third inlet 21101 and / or the fourth opening 2055 on the horizontal plane, more preferably located at its center, so that when the nozzle of the first spray head sprays liquid from top to bottom, some of the liquid directly washes the debris into the second filter box, improving cleaning efficiency.

[0117] In some embodiments, at least a portion of the fourth opening is located above at least a portion of the third inlet; at least a portion of the fourth opening is located below at least a portion of the third opening, so that the waste and liquid in the first filter box fall sequentially from the third opening, the fourth opening and the third opening into the second filter box under their own gravity and / or under the impact force of the liquid sprayed from the first nozzle.

[0118] For example, at least a portion of the fourth opening is located at the top of the third receiving cavity; at least a portion of the third inlet is located at the top of the second filter box, so that the garbage and water in the first filter box can quickly fall into the second filter box from the fourth opening and the third inlet under their own gravity.

[0119] For example, the fourth opening is located directly above the third inlet to ensure that all liquid and waste flowing into the fourth opening 2055 can flow into the third inlet. Alternatively, the area of ​​the fourth opening is smaller than the area of ​​the third inlet to further ensure that all waste entering the fourth opening falls into the second filter box. Or, the projection of the fourth opening onto the horizontal plane falls entirely within the projection of the third inlet onto the horizontal plane, ensuring that all waste entering the fourth opening falls into the second filter box.

[0120] Alternatively, in other embodiments, to ensure that all waste discharged from the first filter box enters the fourth opening, when the pool robot docks on the base station body, the projection of the third opening on the horizontal plane falls entirely within the projection of the fourth opening on the horizontal plane. Alternatively, the fourth opening is located on the upper surface of the base station body, and the projection of the third opening on the upper surface falls entirely within the projection of the fourth opening on the upper surface. Alternatively, the projections of the third and fourth openings on the horizontal plane completely coincide.

[0121] Alternatively, in other embodiments, when the pool robot stops on the base station body, the projection of the third opening on the horizontal plane falls into the projection of the fourth opening on the horizontal plane, and the projection of the fourth opening on the horizontal plane falls entirely into the projection of the third inlet on the horizontal plane, so that all the garbage discharged from the third opening can enter the second filter box through the fourth opening and the third inlet; to avoid the garbage in the first filter box being discharged outside the base station body (for example, the garbage is scattered on the upper surface of the base station body), requiring the user to manually clean the garbage scattered outside the base station body.

[0122] In other words, when the pool robot stops at the cleaning position of the base station body, the third opening is directly above the fourth opening, and the fourth opening is directly above the third inlet. The area of ​​the third opening is smaller than the area of ​​the fourth opening, and the area of ​​the fourth opening is smaller than the area of ​​the third inlet, ensuring that all the garbage discharged from the third opening falls into the fourth opening and then into the second filter box.

[0123] In some embodiments, when the pool robot stops at the cleaning position of the base station body, the first bottom cover of the pool robot opens the third opening, and the first frame of the first filter box remains inside the first body, not extending outside the first body or into the third receiving cavity. That is, the first frame remains above the third receiving cavity or the second filter box. In other embodiments, when the first nozzle sprays liquid onto the first filter box, the first nozzle is located outside the third receiving cavity and the second filter box, and at least a portion of the first nozzle (e.g., the nozzle) is located above at least a portion of the third receiving cavity or at least a portion of the second filter box, so that when the first nozzle sprays liquid onto the side wall and bottom wall of the first filter box, the liquid can rinse the first filter box from top to bottom, making it easier for the sprayed liquid to wash the debris to the third opening and fall into the second filter box more quickly.

[0124] For example, in some embodiments, when the first nozzle sprays liquid into the first filter box, the nozzle of the first nozzle is located above the third receiving cavity or the second filter box; or, the nozzle is located directly above the fourth opening or the third opening, and the projection of the nozzle on the horizontal plane falls into the projection of the fourth opening on the horizontal plane, so that when the nozzle sprays liquid from top to bottom, part of the liquid directly washes the garbage into the second filter box, thereby improving cleaning efficiency.

[0125] For example, in some embodiments, when the first nozzle sprays liquid into the first filter box, the nozzle is located directly above at least a portion of the third opening, directly above at least a portion of the fourth opening, and directly above at least a portion of the third inlet, so that the liquid sprayed by the nozzle can directly flush the waste in the first filter box into the second filter box.

[0126] When the first nozzle is not spraying liquid onto the first filter box, the position of the nozzle is not limited; it can be located inside or outside the base station body. For example, when the first nozzle is cleaning the first filter box, the nozzle is located outside the base station body; when the first nozzle is not cleaning the first filter box, the nozzle can be located outside the base station body or housed inside the base station body; or, the first nozzle can be entirely housed outside the base station body.

[0127] In some embodiments, the base station includes a second dust chamber, the inner cavity of which serves as a third receiving cavity 2054. Further, a fourth opening may be provided on the second dust chamber. For example, a fourth opening may be provided on the top of the second dust chamber to communicate with the outside.

[0128] In some embodiments, the third receiving cavity may not contain a second filter box; that is, the waste and liquid discharged from the first filter box can be directly received or contained within the third receiving cavity. When the pool robot automatically returns to the base station body or the user places the pool robot on the base station body, the waste in the first filter box enters the third receiving cavity through the fourth opening and is discharged outside the base station through the drain outlet. In this embodiment, when the first nozzle sprays liquid onto the first filter box, the nozzle of the first nozzle is located outside the third receiving cavity, and at least a portion of the first nozzle (e.g., the nozzle itself) is located above at least a portion of the third receiving cavity. Compared to other embodiments, this embodiment does not contain a second filter box, and the waste discharged from the first filter box is discharged directly outside the base station without being filtered within the third receiving cavity of the base station.

[0129] The first nozzle 2173 also has two spray direction strategies to suit different cleaning needs: Spraying from the inside out: The first nozzle 2173 extends into the first filter box 1051, spraying from the center outwards to the surrounding side walls and bottom cover. This method provides a strong rinsing force, with the water flow directly acting on the surface where dirt adheres, effectively removing stubborn deposits and achieving the most thorough cleaning effect.

[0130] Spraying from the outside in: The nozzle of the first spray head 2173 is located outside the first filter box 1051, that is, it does not extend into the first filter box. However, the nozzle can extend into the gap between the first receiving cavity and the outside of the first filter box to spray water from the outside into the first filter box. This method is suitable for specific filter screen structures or when the internal space is insufficient to accommodate the spray head. Although the rinsing force is relatively small, it can achieve basic cleaning function.

[0131] The first nozzle 2173 can also have various designs. For example, it can be a simple fixed nozzle that covers all surfaces inside the filter box through multiple nozzles at different angles; it can also be a rotating nozzle that rotates while spraying water for more comprehensive coverage; or it can be a vibrating nozzle that enhances the cleaning effect through high-frequency vibration. These different nozzle designs can be selected according to specific cleaning needs and cost considerations.

[0132] In some embodiments, since the first nozzle extends into the first body through the fourth inlet and the second shielding cover on the fourth inlet is in the open state, some of the liquid sprayed by the first nozzle into the first filter box will splash out of the pool robot from the fourth inlet. The splashed liquid will scatter on the base station or the pool shore, causing a poor user experience.

[0133] To improve user experience and prevent liquid splashing, and to keep the environment around the base station dry and clean, in some embodiments, such as Figure 4 and Figure 5 As shown, the second cleaning assembly also includes a shielding assembly 3000, which is fixed relative to the first nozzle. When the first nozzle is inserted into the first filter box, the shielding assembly is used to close or block at least a portion of the fourth inlet and / or the twelfth opening to prevent the liquid sprayed by the first nozzle from flowing out of the main body from the fourth inlet. When the first nozzle is withdrawn from the main body, the shielding assembly leaves or opens the fourth inlet and the twelfth opening.

[0134] In some embodiments, such as Figures 6 to 9 As shown, the shielding assembly includes a second shielding cover 2177, which is used to shield at least a portion of the fourth inlet to prevent water jets from the first nozzle from flowing out of the main body from the fourth inlet. Alternatively, in another embodiment, the second shielding cover is used to shield at least a portion of the twelfth opening, without shielding the fourth inlet, in which case the second shielding cover is used to prevent water jets from the first nozzle from flowing out of the first filter box from the twelfth opening.

[0135] For example, in one embodiment, when the first nozzle switches from the retracted position to the extended position, the second shield covers the fourth inlet. When some liquid sprayed from the first nozzle splashes onto the fourth inlet, the second shield blocks this portion of liquid within the first body, preventing it from splashing out of the pool robot. When the first nozzle switches from the extended position to the retracted position, the second shield moves with the first nozzle away from the fourth inlet, thus not obstructing it.

[0136] In other words, when the first nozzle 2173 is in the extended position and begins spraying liquid, the second shielding cover is able to cover or block the area around the fourth inlet 1016. In this way, even if a small amount of liquid bounces out from the fourth inlet 1016, it will be blocked by the second shielding cover, preventing the base station surface or the surrounding environment from getting wet, thus keeping the overall area clean and dry.

[0137] In some embodiments, when a second shielding cover is provided, the second baffle and the second shielding cover do not interfere with each other when the second baffle opens the second water inlet and the first nozzle extends into or exits the first filter box through the second water inlet. For example, in some embodiments, such as Figure 19 , Figure 21 and Figure 23 As shown, when the second baffle 10511d opens the second water inlet and the first nozzle extends through the second water inlet into the first filter box, the second shield is approximately located below the second baffle; or, the pivot of the second baffle is approximately located at the upper edge of the second water inlet, so that when the second baffle rotates to open the second water inlet and the first nozzle extends through the second water inlet into the first filter box, the second shield is approximately located below the second baffle, so that the second baffle does not interfere with the movement of the second shield.

[0138] In some embodiments, such as Figures 11-1 to 32 As shown, the blocking assembly also includes a flexible water-blocking member 3001, at least a portion of which is arranged around the outer periphery of the second shielding cover to block the liquid ejected by the first nozzle from flowing out of the first body through the fourth gap 10164 between the second shielding cover and the fourth inlet.

[0139] In some embodiments, such as Figures 11-1 to 22 As shown, the flexible water-blocking component includes a first flexible component 30011. The first flexible component is at least partially wrapped around the outer periphery of the second shielding cover to block at least a portion of the fourth gap, so that the first nozzle can block the fourth gap by means of the first flexible component wrapped around the outer periphery of the second shielding cover, whether it is moving actively or passively.

[0140] For example, in some embodiments, a first flexible member is wrapped around the outer circumference of the second shielding cover to shield the fourth gap. When the first nozzle performs a telescopic movement or a rotational movement, the fourth gap can be shielded by the first flexible member wrapped around the outer circumference of the second shielding cover.

[0141] In some embodiments, such as Figure 18As shown, the first flexible member includes a first open end 30011a, a second open end 30011b, and a buffer cavity 30011c. The first open end is at least partially surrounding the outer periphery of the second shielding cover, and the buffer cavity extends from the first open end to the second open end. When the first nozzle is inserted into the first filter box, at least a portion of the buffer cavity is located within the twelfth opening, and the second open end is close to, adjacent to, or extends into the inner cavity of the first filter box, allowing liquid in the buffer cavity to flow into the first filter box. In this embodiment, the water jet from the first nozzle is sprayed into the buffer cavity, where the buffer cavity cushions the impact force generated by the sprayed water jet, and the water then flows from the buffer cavity into the first filter box.

[0142] Furthermore, in some embodiments, reference is made to Figure 18 and Figure 19 As shown, the bottom of the buffer chamber slopes downwards from the first opening end to the second opening end. This sloped bottom design guides the liquid in the buffer chamber into the first filter box, preventing water accumulation in the buffer chamber.

[0143] In some embodiments, when the first nozzle moves in a telescopic motion, the fourth gap can be perfectly blocked using only the first flexible member.

[0144] In some embodiments, such as Figures 11-1 to 22 As shown, the flexible water-blocking component also includes at least one second flexible component 30012, which is at least partially wrapped around the second opening end of the first flexible component and extends outward; when the first nozzle is inserted into the first filter box, there is a first gap 10161 between the first flexible component and the twelfth opening, and the second flexible component is located in the first filter box to block at least a portion of the first gap.

[0145] In some embodiments, such as Figure 26 , Figure 27 As shown, when the first nozzle extends into the first filter box, a second gap 10162 is formed between the second flexible member and the inner wall of the first filter box. The purpose of this second gap is to prevent the second flexible member from abutting against the inner wall of the first filter box. When the first nozzle exits the first filter box, the second flexible member is stuck at the twelfth opening and cannot exit smoothly from the twelfth opening. That is, the purpose of the second gap is to provide sufficient deformation space for the second flexible member so that it can exit smoothly from the twelfth opening after deformation; or, in another embodiment, the second flexible member abuts against or is close to the inner wall of the first filter box.

[0146] In some embodiments, such as Figures 13 to 21As shown, the second flexible member includes a first blocking section 30012a, at least a portion of which is disposed on the bottom of the second opening end. At this time, the first gap includes a first sub-gap 10161a between the bottom of the first flexible member and the bottom of the twelfth opening. When the first nozzle extends into the first filter box, the first blocking section is located inside the first filter box and is used to block at least a portion of the first sub-gap.

[0147] Furthermore, in some embodiments, such as Figures 22 to 32 As shown, when the first nozzle extends into the first filter box, the bottom of the first shielding section is lower than the bottom of the twelfth opening to better shield at least a portion of the first sub-gap.

[0148] In some embodiments, the first blocking segment is substantially flush with the end face of the second opening end and is in a substantially vertical position to more effectively block at least a portion of the first sub-gap.

[0149] In some embodiments, such as Figure 19 As shown, the second flexible member also includes a second blocking section 30012b, which is disposed on the first side portion 30011b1 at the end of the second opening; at this time, the first gap also includes a second sub-gap 10161b formed between one side portion of the first flexible member and one side portion of the twelfth opening; when the first nozzle extends into the first filter box, the second blocking section is located inside the first filter box and is used to block at least a portion of the second sub-gap.

[0150] In some embodiments, such as Figure 19 As shown, the end face of the second shielding section is not flush with the end of the second opening. For example, the second shielding section includes a first end 30012b1 and a second end 30012b2, with the first end connected to the end of the second opening. Specifically, along the direction from the first opening end to the second opening end, the second end is further away from the second shielding cover than the first end. Alternatively, the first end is closer to the third flexible member than the second end, i.e., the second end faces away from the third flexible member. This arrangement allows the second shielding section to gradually retract with minimal deformation when the first nozzle pulls the flexible water-blocking member out of the twelfth opening and the fourth inlet, preventing the second shielding section from getting stuck in the twelfth opening and the fourth inlet, and ensuring smooth entry and exit of the first nozzle from the first filter box.

[0151] Furthermore, in some embodiments, the outer edge of the second blocking segment is located outside the first side of the twelfth opening to better block at least a portion of the second sub-gap.

[0152] In some embodiments, such as Figure 14As shown, the second flexible member also includes a third blocking section 30012c, which is disposed on the second side portion 30011b2 at the end of the second opening, with the first side portion and the second side portion being distributed opposite to each other. The first gap also includes a third sub-gap 10161c formed between the other side portion of the first flexible member and the other side portion of the twelfth opening. When the first nozzle extends into the first filter box, the third blocking section is located inside the first filter box and is used to block at least a portion of the third sub-gap.

[0153] In some embodiments, such as Figure 14 As shown, the end face of the third shielding section is not flush with the end face of the second opening. For example, the third shielding section includes a third end 30012c1 and a fourth end 30012c2. The third end is connected to the end of the second opening. Along the direction from the end of the first opening toward the end of the second opening, the fourth end is further away from the second shielding cover than the third end. Or, the third end is closer to the third flexible member than the fourth end, i.e., the fourth end faces away from the third flexible member. This arrangement facilitates the gradual retraction and minimal deformation of the third shielding section when the first nozzle drives the flexible water-blocking member out of the twelfth opening and the fourth inlet, ensuring that the third shielding section does not get stuck in the twelfth opening and the fourth inlet, and ensuring a smooth process for the first nozzle to enter or exit the first filter box.

[0154] In some embodiments, the outer edge of the third blocking segment is located outside the other side of the twelfth opening to better block at least a portion of the second sub-gap.

[0155] In some embodiments, such as Figure 14 As shown, the second shielding section and the first shielding section are connected by at least one transition section 30014. The thickness of the transition section is less than the thickness of the first shielding section and the thickness of the second shielding section. This thinning of the transition section allows for greater deformation, making it easier to deform. When the first nozzle drives the flexible water-blocking component to rotate, the large deformation of the transition section prevents the first and second shielding sections from getting stuck in the twelfth opening and the fourth inlet during the rotation of the first nozzle.

[0156] In some embodiments, such as Figure 13 , Figure 14 and Figure 17 As shown, the second flexible member also includes a fourth blocking section 30012d, which is disposed on the top of the second opening end. The first gap includes a fourth sub-gap 10161d formed between the top of the first flexible member and the top of the twelfth opening; when the first nozzle extends into the first filter box, the fourth blocking section is located inside the first filter box and is used to block at least a portion of the fourth sub-gap.

[0157] In some embodiments, the fourth blocking segment extends generally vertically and is flush with the end face of the second opening end to more effectively block at least a portion of the fourth sub-gap.

[0158] In some embodiments, the second flexible member is integrally disposed around the outer circumference of the second opening end to cover the first gap. For example, as... Figures 13 to 21 As shown, the first shielding segment, the second shielding segment, the third shielding segment, and the fourth shielding segment are connected in sequence and form a ring, so that the second flexible member is wrapped around the outer circumference of the second opening end.

[0159] Alternatively, in other embodiments, viewed as a whole, the second flexible member is generally flared in the direction from the first opening end toward the second opening end. This allows the flared section of the second flexible member to gradually close as the first nozzle pulls the flexible baffle out of the twelfth opening and the fourth inlet, preventing the second flexible member from getting stuck in the twelfth opening and the fourth inlet, and ensuring smooth entry and exit of the first nozzle into or from the first filter box.

[0160] In some embodiments, such as Figures 14 to 21 As shown, the first flexible member also includes an annular protrusion 300111, which is provided on the end of the first opening. An annular groove 300111a is provided on the inner wall of the annular protrusion. The first flexible member is sleeved on the outer periphery of the second cover through the annular groove.

[0161] In some embodiments, such as Figure 14 and Figure 21 As shown, the annular protrusion includes a first portion fitted onto the bottom of the second shielding cover; the first portion includes at least an outer sidewall 300111b and an inner sidewall 300111c, with the upper edge of at least a portion of the outer sidewall higher than the upper edge of at least a portion of the inner sidewall. Due to the obstruction of the outer sidewall, liquid entering the annular groove cannot be discharged from the annular groove to the outside of the first body; if the height of the outer sidewall is lower than the height of the inner sidewall, the liquid entering the annular groove will flow out from the outer sidewall of the annular groove, and then flow out of the first body.

[0162] In some embodiments, such as Figure 13 As shown, the flexible water-blocking component also includes at least one third flexible component 30013. At least a portion of the third flexible component is wound around the outer wall of the first flexible component and extends outward. The third flexible component is located between the first opening end and the second opening end. When the first nozzle is inserted into the first filter box, a third gap 10163 exists between the top of the first flexible component and the top of the fourth inlet. The third flexible component is at least used to prevent liquid entering the third gap from flowing out towards the fourth inlet to the outside of the first body, even if liquid in the third gap flows into the first filter box from the twelfth opening.

[0163] In one embodiment, such as Figure 28 As shown, when the first nozzle extends into the first filter box, a fifth gap 10165 is formed between the bottom of the third flexible member and the bottom of the fourth inlet. The purpose of this fifth gap is to prevent the bottom of the third flexible member from abutting against the bottom of the fourth inlet, so that when the first nozzle exits the first filter box, the third flexible member is stuck at the fourth inlet and cannot exit smoothly from the fourth inlet. That is, the purpose of the fifth gap is to provide sufficient deformation space for the third flexible member so that it can exit smoothly from the fourth inlet after deformation; or, in another embodiment, the bottom of the third flexible member abuts against or is close to the bottom of the fourth inlet.

[0164] Furthermore, in some embodiments, such as Figures 25 to 28 As shown, the bottom of the fourth inlet is provided with an upwardly protruding first rib 10166. When the first nozzle extends into the first filter box, the third flexible member is located between the first rib and the second flexible member. The first rib is used to at least block the liquid in the fifth gap from flowing out of the fourth inlet, so that the liquid in the fifth gap can flow into the first filter box from the twelfth opening.

[0165] In some embodiments, such as Figures 13 to 21 As shown, the third flexible member includes at least a fifth blocking section 300131, which is wrapped around at least a portion of the first flexible member to block liquid entering the third gap from flowing out toward the fourth inlet to the outside of the first body through the fifth blocking section.

[0166] Furthermore, in some embodiments, the second and fifth blocking sections are located on the same side of the first flexible member to further prevent liquid from flowing out of the fourth inlet. When the first nozzle rotates, due to the change in the rotation angle of the first nozzle, the second blocking section contacts the fourth inlet before the fifth blocking section during the rotation of the first nozzle. Furthermore, in some embodiments, the outer edge of the second blocking section protrudes beyond the outer edge of the fifth blocking section, so that during the rotation of the first nozzle, the second and fifth blocking sections can smoothly and sequentially extend into the fourth inlet, ultimately placing the second blocking section within the twelfth opening and the fifth blocking section within the fourth inlet.

[0167] In some embodiments, such as Figure 16 , Figure 17As shown, one end of the second shielding cover protrudes from one side of the first flexible member, so that the annular protrusion has a first extension 300111d protruding from the first flexible member. The first extension and the fifth shielding section are located outside the same side of the first flexible member to further prevent liquid from flowing out of the fourth inlet. When the first nozzle rotates, due to the change in the rotation angle of the first nozzle, the fifth shielding section contacts the fourth inlet before the first extension during the rotation of the first nozzle. Furthermore, the outer edge of the fifth shielding section protrudes from the outer edge of the first extension, so that the fifth shielding section can smoothly enter the fourth inlet during the rotation of the first nozzle. Finally, the first extension is located outside the fourth opening, and the fifth shielding section is located inside the fourth inlet.

[0168] In some embodiments, such as Figure 15 As shown, the third flexible member also includes a sixth shielding section 300132, which is connected to the fifth shielding section and forms a ring, so that the third flexible member is arranged around the outer wall or the outer periphery of the first flexible member.

[0169] In some embodiments, such as Figure 21 As shown, the top of the third flexible member is provided with a thinning portion 300133. When the first nozzle extends into the first filter box, the thinning portion is close to, near, or abuts the top of the fourth inlet. When the first nozzle extends into the first filter box, the top of the third flexible member abuts or is close to the top of the fourth inlet; furthermore, in order to ensure that the top of the third flexible member does not affect the rotation of the first nozzle, the thickness of the top of the third flexible member is less than the thickness of other parts of the third flexible member, that is, by reducing the thickness of the third flexible member, the deformation of the third flexible member is increased, so that the third flexible member can generate a larger deformation during the rotation of the first nozzle, so that it will not get stuck on the top of the fourth inlet.

[0170] In some embodiments, such as Figure 20 As shown, the third flexible member includes a fifth end 30013a and a sixth end 30013b. The fifth end is arranged around the first flexible member, and the sixth end is away from the first flexible member. A thinning portion is provided on the sixth end to increase the deformation of the sixth end. By increasing the deformation of the third flexible member, the third flexible member can generate a larger deformation during the rotation of the first nozzle, so that it will not get stuck on the fourth inlet.

[0171] In some embodiments, such as Figure 22As shown, along the direction from the first opening end to the second opening end, the top of the buffer cavity has a first length, and the bottom of the buffer cavity has a second length. The first length is less than the second length, so as to form a first notch 30011b3 at the top of the second opening end. The first flexible member also includes a second extension 300111e, which is disposed at one end of the first notch. The second extension is adjacent to or close to the third flexible member to prevent liquid from flowing from the first notch into the sixth gap 30015 between the third flexible member and the first flexible member.

[0172] In some embodiments, the flexible water-blocking component is made of one or more of the following materials: rubber, silicone, polyurethane, polymer composite material, foam material, coated fabric, etc.

[0173] In some embodiments, the second shielding cover may be made of a flexible or rigid material. In some embodiments, the material of the second shielding cover is the same as that of the flexible water-blocking element, both being flexible materials; or, in other embodiments, the material of the second shielding cover is different from that of the flexible water-blocking element, for example, the second shielding cover is made of a rigid material and the flexible water-blocking element is made of a flexible material.

[0174] In some embodiments, the first shielding cover and the flexible water-blocking member are integrally disposed; or, in other embodiments, the first shielding cover and the flexible water-blocking member are separately disposed.

[0175] In some embodiments, the shape of the second shielding cover matches the shape of the fourth inlet 1016, such as both being approximately circular, elliptical, rectangular, etc., to optimize the sealing effect.

[0176] In one embodiment, such as Figure 1 As shown, the height h1 of the second water inlet is not less than the maximum height h2 of the first nozzle, so that the first nozzle can smoothly extend into the pool robot from the second water inlet, or exit from the pool robot.

[0177] In addition, the base station 2000 can be equipped with various sensors and intelligent control functions. For example, it can detect the amount of debris in the second filter box 21102 using a weight sensor or optical sensor, and remind the user to empty it when it is close to full capacity; it can monitor the water consumption during the cleaning process using a flow sensor to optimize cleaning parameters; it can ensure that the pool robot 1000 accurately docks at the cleaning position using a position sensor; and it can connect to the user's mobile APP through a communication module to provide remote monitoring and control functions, thereby further enhancing the product's technological feel and user experience.

[0178] In terms of manufacturing processes and material selection, key components such as the first nozzle 2173 can be made of corrosion-resistant materials such as stainless steel and engineering plastics to ensure long-term reliability in humid environments. The second filter box 21102 can be made of a semi-transparent material, allowing users to visually understand the waste collection status. Sealing rings and waterproof adhesives can be used at all connection points to ensure good sealing performance.

[0179] In some embodiments, the second cleaning component can be configured as a detachable modular structure. For example, the second cleaning component can be integrated into a whole to form a modular structure, thereby realizing modular assembly. This allows the second cleaning component to be assembled into modules separately before being installed on the base station. This makes installation and disassembly convenient and easy to produce. At the same time, it also makes it easy to disassemble or replace parts during after-sales maintenance.

[0180] The detachable connection mentioned in this application is made by means of at least one of the following: threaded connection, magnetic connection, snap-fit ​​connection, key pin connection, locking connection, plug connection, grooved connection, screw connection, etc.

[0181] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the above-described division of functional units and modules is merely an example. In practical applications, the above functions can be assigned to different functional units and modules as needed, that is, the internal structure of the device can be divided into different functional units or modules to complete all or part of the functions described above. The functional units and modules in the embodiments can be integrated into one processing unit, or each unit can exist physically separately, or two or more units can be integrated into one unit.
