[0005] This disclosure relates to the field of pool cleaning equipment technology, and more particularly to a pool robot and cleaning system. Background Technology

[0006] 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.

[0007] 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

[0008] This application aims to solve the above-mentioned problems. It discloses a base station and a cleaning system that can automatically filter the garbage inside the base station again and discharge the 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 the garbage inside the base station from smelling bad. At the same time, it discloses a first filter box with a third opening at the bottom, so that the garbage in the first filter box can smoothly enter the second filter box under the action of gravity and water flow.

Detailed Implementation

[0037] 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.

[0038] like Figures 1 to 45 As shown, an exemplary embodiment of this disclosure provides a cleaning system. The cleaning system includes a cleaning device 1000 and a base station 2000, wherein the base station is at least used to clean a first filter cartridge 1051 of the cleaning device, so that debris in the first filter cartridge is transferred from the pool robot or temporarily stored in the base station. Further, as... Figures 1 to 5 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 the second filter box is located within the base station body. The second filter box is used to receive and further filter debris from the first filter box. The base station body can be the housing of the base station, used to support and house other functional components.

[0039] The Pool Robot 1000 is the main working unit of the cleaning system, responsible for performing cleaning tasks in the pool.

[0040] Base station 2000 serves as the support center for the cleaning system, providing services such as docking, cleaning, and charging for the pool robots. The base station body 20001 constitutes the main support structure of the base station, with a resting surface on its top for the pool robots to dock.

[0041] The base station disclosed in this application can be used on land, for example, by placing it on the bank of a pool or on the ground. In this case, the base station is in an air environment, and a pool robot can automatically get out of the pool and walk onto the base station. For example, see reference... Figure 18 As shown, the base station also includes a carrier 2040, one end of which is mounted on the base station body, and the other end of which extends below the surface of the water in the pool, allowing the pool robot to walk from the pool onto the carrier and then back onto the base station body. Alternatively, the pool robot can be manually moved onto the base station body by the user.

[0042] When the base station is used on shore or on the ground, the first filter box is in the air, and the first nozzle sprays water at least to the side and / or bottom of the first filter box to rinse the side and / or bottom of the first filter box, not only flushing the garbage inside the first filter box out of the first filter box, but also washing away the garbage attached to the side and / or bottom of the first filter box.

[0043] In addition to cleaning the first filter box using the first nozzle as described above, users can also clean the first filter box manually using a water gun. In some embodiments, the first filter box can also be manually cleaned. For example, users can use a water gun to clean the first filter box. Scenarios for using a water gun include: when the user finds that the first filter box is not completely clean after cleaning, the user can choose to use a water gun to further clean the dust box; or, when the cleaning program is not triggered for some reason, resulting in the first filter box not being cleaned, the user can also choose to use a water gun to further clean the dust box; or any other situation where the user wants to manually clean the first filter box. In this embodiment, during the cleaning operation of the first filter box, the first filter box can be located inside the main body of the cleaning equipment. At this time, the water gun can be inserted into the main body of the cleaning equipment from the fourth inlet or the first nozzle extension inlet and reach the space where the first filter box is located to clean the first filter box. In this case, there is no need to remove the first filter box; simply insert the water gun into the main body of the cleaning equipment, which is convenient. Alternatively, the first filter box can be removed from the main body of the cleaning equipment first, and then rinsed with the water gun. In this case, the first filter box is completely exposed outside the main body of the cleaning equipment, which facilitates rinsing of the first filter box with the water gun and can further improve the cleaning effect. Alternatively, when the first filter box is located inside the main body of the cleaning equipment, the first filter box can be cleaned through the first nozzle, and then the first filter box can be removed from the main body of the cleaning equipment and rinsed with the water gun to further improve the cleaning effect of the first filter box.

[0044] When using a water gun to clean the first filter box and / or the second filter box, the water gun can be referred to as the second nozzle. The water source for the water gun can be the same as the water source for the first nozzle, and the water gun can be connected to the water source via a water pipe.

[0045] In one embodiment, the second base station further includes at least one T-connector. The first end of the T-connector is connected to a clean water source, for example, a household faucet can be connected to provide clean water. The second end of the T-connector is connected to a first nozzle, for example, the second end of the T-connector can be directly connected to the first nozzle, or the second end of the T-connector can be connected to one end of a water pipe, and the other end of the water pipe can be connected to the first nozzle. The third end of the T-connector is connected to a water gun or a second nozzle. Thus, the first filter box and / or the second filter box can be rinsed via the first nozzle and / or the second nozzle through the T-connector.

[0046] When cleaning the debris inside the second filter box, the second filter box can be pulled out of the base station body first, and then the debris inside can be emptied; alternatively, if the second filter box contains a second filter bag, the second filter box can be pulled out of the base station body first, and then the second filter bag can be removed directly. After cleaning the debris collected in the second filter box, if there is still debris or stains remaining, the second filter box can be further cleaned by water flow, airflow, vibration, high temperature, or a combination thereof.

[0047] In some embodiments, the second filter box can be further cleaned by water flow. For example, in some embodiments, the second filter box can be cleaned by water sprayed from the first nozzle and / or the second nozzle, in which case the second filter box may or may not be returned to the base station body. For example, in one embodiment, the second filter box may be located inside the base station body, i.e., returned to the base station body, in which case the second nozzle can extend into the base station body from the fourth opening and reach the space where the second filter box is located to clean the second filter box; or, the second filter box may be located outside the base station body, i.e., not returned to the base station body, and the second filter box can be directly rinsed by the first nozzle and / or the second nozzle. Alternatively, in other embodiments, the second filter box can be directly placed under other water sources for rinsing.

[0048] When the base station is placed on the shore or on the ground, the water source for cleaning the first filter box can be municipal water from the user's home. For example, water from a tap. Since municipal water is pumped to the user's tap, the base station may or may not need to have a first water pump. Alternatively, the water source for cleaning the first filter box can be other types of water, such as water from a pool or river. In this embodiment, the base station needs to include at least one first water pump, which draws water from the pool or river to the first nozzle, causing the nozzle to spray water.

[0049] 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.

[0050] The base station disclosed in this application can also be placed inside a pool or in a placement area connected to the pool. For example, the base station can be placed on a raised platform inside the pool. For example, the raised platform can be a sun deck or steps within the pool, wherein the sun deck and steps can be separated in the pool, or the sun deck can serve as a step surface of the steps. Alternatively, a recessed placement area can be provided on the pool bank, and the placement area can be connected to the pool through an opening in the pool wall, where the base station can be installed. Alternatively, the base station can be installed on the pool wall; or on the bottom of the pool; or it can be placed in other locations within the pool. When the base station is installed inside the pool or in a placement area, a pool robot can automatically walk back to the base station body from the pool; or, the pool robot can be manually carried to the base station body by a user.

[0051] 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.

[0052] 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.

[0053] The main body of the pool robot is provided with at least one first water outlet, and at least part of the first water outlet is located on the top of the main body. When the pool robot cleans the liquid in the pool, the liquid filtered by the first filter box is discharged out of the pool robot through the first water outlet.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] Alternatively, in some embodiments, the operation of the second water pump adjusts the height of the second liquid level in the first filter box to a preset height; once the second liquid level reaches the preset height, it is kept at the preset height to facilitate the first nozzle spraying liquid to clean the side of the first filter box.

[0059] 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.

[0060] In other words, if most or all of the first filter screen is below the second liquid surface, the liquid in the first filter box needs to be sucked away by the operation of the second water pump, so that most of the first filter screen is above the second liquid surface, that is, the first filter screen is in the air environment, which makes it easier for the first nozzle to spray liquid onto the first filter screen to wash away the garbage attached to the first filter screen.

[0061] 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.

[0062] 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, or an elevated water tank. Alternatively, 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.

[0063] 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.

[0064] 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.

[0065] like Figures 1 to 4 , refer to Figure 18 , Figure 22 , Figure 26 , Figure 31 , Figure 35As shown, in some embodiments, the base station further includes a second cleaning component, which includes at least a first nozzle 2173; wherein the first nozzle cleans the first filter box 1051 by spraying liquid onto it. When the pool robot stops on the base station body, it sprays liquid through the first nozzle to clean the first filter box, and the debris in the first filter box falls into the second filter box, thereby transferring the debris in the first filter box into the second filter box.

[0066] In some embodiments, the liquid sprayed by the first nozzle, i.e. the cleaning water source, can be water from a swimming pool, pool, or river; or tap water supplied to a water tank, faucet, or shower head; or cleaning fluid to further remove oil, stubborn stains, 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 fluid; or a mixture of water from a swimming pool, pool, or river and cleaning fluid.

[0067] 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, which serves as the entry point for waste into the second filter box.

[0068] For example, such as Figures 1 to 4 As shown, when the pool robot is stationary on the base station body, the third inlet can connect with the third opening of the first filter box, allowing the waste in the first filter box to enter the second filter box through the third opening and the third inlet. When the pool robot is stationary on the base station body, the first nozzle sprays liquid onto the first filter box. After the first bottom cover 1054 of the first filter box opens the third opening, the waste 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 waste 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 waste from the first filter box into the second filter box, completing the cleaning of the first filter box.

[0069] In the above embodiments, during the process of the first nozzle spraying liquid into the first filter box, the first bottom cover opens the third opening so that when the first nozzle sprays liquid into the first filter box, the garbage immediately falls out of the first filter box through the third opening, thus preventing a large amount of garbage from remaining in the first filter box during the rinsing process and affecting the cleaning efficiency of the first filter box; or, in other embodiments, during the process of the first nozzle spraying liquid into the first filter box, the first bottom cover keeps the third opening closed so that a certain amount of water is retained in the first filter box to soak the garbage in the first filter box and improve the cleaning effect of stubborn garbage.

[0070] In some embodiments, the second filter box includes a second frame and a second filter screen. The second filter screen is disposed on the second frame to form a filter surface. Alternatively, in other embodiments, the second filter box is a first filter bag, which can be a disposable filter bag or a reusable filter bag. If the second filter box is a disposable filter bag, when the first filter bag is full of garbage, the first filter bag can be directly discarded to replace it with a new one, without the need to clean the first filter bag. Alternatively, the second filter screen can be replaced with filter cotton, which can be disposed outside or inside the second frame.

[0071] In some embodiments, a second filter bag (not shown in the figure) is also provided inside the second filter box. The second filter bag has a fifth inlet that communicates with the third opening. The second filter bag is used at least to collect waste that falls into the first filter box; the second filter box is used at least to perform secondary filtration on the liquid filtered by the second filter bag. The dual-layer filtration of the second filter bag and the second filter box further improves the filtration efficiency of the waste. Furthermore, the second filter bag is detachably disposed inside the second filter box for easy periodic replacement.

[0072] 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.

[0073] In some embodiments, such as Figures 1 to 10 As shown, the pool robot 1000 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 pool liquid to enter the first body 1001, enabling the robot to clean at least one of the pool bottom, pool walls, waterline, and water surface. The liquid outlet is used to discharge the liquid filtered by the first filter assembly out of the first body. The suction assembly generates suction force to guide the liquid flow. The first filter box filters the dust-laden water, leaving debris inside. Under the action of the suction assembly, the dust-laden water in the pool is drawn into the first filter box through the liquid inlet, filtered, and the debris remains inside. The filtered liquid, after passing through the suction assembly, is finally discharged out of the first body through the liquid outlet.

[0074] In one embodiment, such as Figure 7 Zhihe Figure 10As 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 one embodiment, there is one first outlet. Alternatively, in other embodiments, there are multiple first outlets; for example, there are two, three, or more first outlets.

[0075] In other embodiments, such as Figures 1 to 10 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 for cleaning the water surface and water line.

[0076] In other embodiments, the liquid inlet includes at least the aforementioned first water inlet and second water inlet.

[0077] In some embodiments, such as Figure 9 , Figure 10 As shown, the first water inlet is located at the bottom of the first main body; correspondingly, as... Figures 7 to 8 As shown, the first filter box is provided with a first inlet 10511a, which is connected to a first water inlet, so that liquid in the pool enters the first filter box through the first water inlet for filtration. In some other embodiments, the first filter box is provided with a second inlet 10511b, which is connected to a second water inlet, so that liquid on the surface of the pool enters the first filter box through the second water inlet for filtration.

[0078] For example, the first inlet is located at the bottom of the first filter box, and the first inlet is connected to the first water inlet. In other embodiments, when the second water inlet is located on the front side wall of the first main body, correspondingly, the second inlet is located on the front side wall of the first filter box, and the second water inlet is located in front of and connected to the second inlet; or, when the second water inlet is located on the rear side wall of the first main body, correspondingly, the second inlet is located on the rear side wall of the first filter box, and the second water inlet is located behind and connected to the second inlet, so that the pool liquid can directly enter the first filter box from the second water inlet and the second water inlet. That is, the second water inlet is located outside the second inlet.

[0079] In other embodiments, such as Figures 7 to 10 As shown, the first inlet is located at the bottom of the first filter box, with the bottom of the first filter box exposed above the first main body or connected to the outside. Liquid in the pool enters the first filter box through the first inlet. That is, the first inlet and the first outlet are a single opening; or, as shown... Figure 11 As shown, a first protrusion 10523 is provided on the bottom of the first filter box. The first protrusion extends into the first filter box and is hollow to form a liquid inlet channel. The outer end of the liquid inlet channel serves as the first water inlet, and the inner end of the liquid inlet channel serves as the first inlet, so that the liquid in the pool enters the first filter box through the first water inlet and the first inlet. The first protrusion moves synchronously with the first bottom cover to open or close the third opening. Alternatively, the entire liquid inlet channel can be used as the first water inlet or the first inlet.

[0080] In some embodiments, such as Figures 7 to 9 As shown, a second baffle 10511d is provided at the second water inlet. When the pool robot is cleaning the water surface, the second baffle is in the open state, allowing liquid to enter the first filter box through the second water inlet. In some embodiments, the second baffle is rotatably disposed on the first body to open or close the second water inlet. For example, the second baffle can be opened by rotating outward toward the first body; the second baffle can be closed 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 into or exits the first filter box through the second water inlet.

[0081] In some embodiments, such as Figures 1 to 5 , Figures 7 to 10 As shown, the first main body is provided with a fourth inlet 1016, which is connected to 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 main body to spray liquid onto the first filter box, the liquid sprayed by the first nozzle can be effectively applied to the first filter box, ensuring its cleaning effect.

[0082] In some embodiments, such as Figures 1 to 5 , Figures 7 to 10 As shown, the fourth inlet can be the first water inlet or the second water inlet; when the first body is provided with a pick-up and drop-off port, the fourth inlet can also be a pick-up and drop-off port, which is used for the user to put the first filter box into the first body or take out the first filter box from the first body; or, in some other embodiments, the fourth inlet can be independent of the first water inlet and the second water inlet, and the pick-up and drop-off port is provided on the first body.

[0083] In some embodiments, such as Figure 7As shown, the pool robot also includes a loading / unloading port 1017, which communicates with the interior of the first main body and is used for the user to place the first filter box into or remove the first filter box from the first main body. This loading / unloading port can be located on the top, side wall, or bottom of the pool robot. Furthermore, in some embodiments, the pool robot also includes a first cover 1018, which is movably disposed at the loading / unloading port to open or close the port.

[0084] In some embodiments, such as Figure 9 , Figure 10 As shown, the pool robot also includes at least two walking mechanisms. Each walking mechanism 1071 is located on the bottom or side of the first main body and is used to drive the pool robot to walk on the pool bottom and walls. Each walking mechanism 1071 includes a drive motor, a first walking wheel, a second walking wheel, and a track wrapped around the outer periphery of the first and second walking wheels. The track and the two walking wheels form an area. The drive motor drives the first walking wheel to rotate, thereby causing the track and the second walking wheel to rotate. There are two walking mechanisms, located on opposite sides of the first main body 1001.

[0085] In some embodiments, the pool robot further includes a propulsion mechanism, which is at least adapted to drive the pool robot to move in or on the surface of the water. For example, such as Figure 6 As shown, the propulsion mechanism includes at least one first thruster 10721. The first thruster is used to drive the pool robot to walk on the water surface or on the pool wall. The first thruster generates an upward thrust on the pool robot, ensuring that the pool robot can walk on the pool wall and preventing the pool robot from falling off the pool wall. For example, there are two first thrusters 10721, which are symmetrically arranged on both sides of the pool robot. By changing the speed difference between the two first thrusters, the pool robot can turn or turn on the water surface or on the pool wall.

[0086] In some embodiments, the pool robot further includes a first cleaning component, such as Figure 9 , Figure 10 As shown, for example, the first cleaning component includes a main roller brush 1131. In some embodiments, there may be two main roller brushes, respectively disposed at a first end and a second end of the first body 1001, and located at the bottom of the pool robot, for scrubbing the pool bottom, pool walls, or waterline. Alternatively, there may be one main roller brush, disposed at either the first or second end of the first body. In other embodiments, the first cleaning component further includes a side brush 1132 for scrubbing the pool walls or waterline. For example, the side brush is disposed at the first end.

[0087] In some embodiments, such as Figure 6As shown, the pool robot also includes at least one lateral propulsion assembly, which comprises a fourth flow channel 115a (i.e., a lateral flow channel), a motor 115b (i.e., a lateral motor), and a second impeller 115c (i.e., a lateral impeller). At least a portion of the fourth flow channel is located on the side of the first main body. One end of the fourth flow channel has a first opening 115d, and the other end has a second opening 115e. One of the first and second openings serves as a fluid inlet, and the other end serves as a fluid jet outlet. The motor and the second impeller are both located within the fourth flow channel. The lateral propulsion assembly provides the pool robot with a thrust component along its lateral direction, driving the pool robot to move laterally on the water surface, in the water, on the pool bottom, and on the pool walls.

[0088] In some embodiments, the pool robot further includes an surfacing and diving mechanism. For example, the surfacing and diving mechanism is disposed within the first body. The surfacing and diving mechanism is used to drive the pool robot to rise from underwater to the surface and enable the pool robot to float on the water surface; it can also be used to drive the pool robot to dive from the surface to underwater. That is, the surfacing and diving mechanism enables the pool robot to switch between underwater and surface conditions.

[0089] In some embodiments, the surfacing and diving mechanism includes at least one float cavity, at least one first adjusting member, and at least one air inlet. The float cavity is used to contain at least gas. One end of the air inlet communicates with the outside, and the other end communicates with the float cavity or the first adjusting member. The first adjusting member is used to adjust the volume of gas in the float cavity. Under the action of the first adjusting member, outside gas enters the float cavity through the air inlet to increase the volume of gas in the float cavity; or, gas in the float cavity is discharged outside the float cavity through the air inlet to reduce the volume of gas in the float cavity. In some embodiments, the float cavity is flexible. In other embodiments, the float cavity is rigid, and the surfacing and diving mechanism further includes a draining section, which includes a discharge outlet. One end of the draining section communicates with the outside, and the other end communicates with the float cavity or the first adjusting member. Under the action of the first adjusting member, outside gas can be driven to enter the float cavity through the air inlet, increasing the volume of gas entering the float cavity, thereby squeezing the liquid in the float cavity out of the float cavity through the draining section, thus increasing the volume of gas in the float cavity and reducing the volume of liquid. In some embodiments, the first adjusting member is an air pump.

[0090] In some embodiments, the pool robot and / or base station may also be equipped with a chemical dispensing component for dispensing chemicals into the pool to treat the water. For example, the chemicals may be reagents for desalination, clarification, disinfection, etc. The chemical dispensing component includes at least a chemical storage component and a dispensing drive component. The dispensing drive component is used to drive and control the flow of chemicals from the chemical storage component through the chemical outlet. In some embodiments, the dispensing drive component includes at least a motor.

[0091] In some embodiments, the pool robot and / or base station may also be equipped with a water quality detection component for acquiring water quality data from various areas of the pool. This data may include pH value, turbidity, total solids content, salinity, etc., to allow users to understand the water quality in the pool. The water quality detection component includes at least a detection strip, a detection assembly, a peeling element, and a drive assembly. The detection strip includes a test strip and a protective film. When water quality testing is required, the peeling element peels off the protective film and the test strip, exposing the detection color patch on the test strip to contact the liquid. When the liquid contacts the detection color patch on the test strip, the color patch changes color. The detection assembly collects the color change data, and the control system processes and compares the data from the detection assembly to obtain water quality testing information. In some embodiments, the drive assembly includes at least a motor.

[0092] 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 35 and Figure 39 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 shield at least a portion of the fourth inlet and / or the second inlet 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 second inlet.

[0093] In some embodiments, such as Figure 35 , Figure 39 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 body from the fourth inlet.

[0094] In some embodiments, such as Figure 39 As shown, the shielding 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 sprayed by the first nozzle from flowing out of the first body through the fourth gap between the second shielding cover and the fourth inlet.

[0095] In some embodiments, in order to discharge the waste from the first filter box, such as Figures 1 to 4 , Figure 8 , Figure 11 As 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. For example, the first bottom cover has an operating state with the third opening open and a non-operating state with the third opening closed.

[0096] When the first filter box is inside the pool robot, the first bottom cover has an operating state with the third opening open and a non-operating state with the third opening closed. For example, when cleaning the first filter box, such as when the pool robot is stationary on the base station and the base station's first nozzle cleans the first filter box by spraying liquid, or when cleaning the first filter box in other ways, the first bottom cover is in the operating state to allow waste to be discharged; when the pool robot is performing a cleaning task, the first bottom cover is in the non-operating state to prevent waste collected in the first filter box from leaking out from the bottom during the movement of the pool robot. Specifically, when cleaning the first filter box, the first bottom cover is in the operating state, at which time the first bottom cover can rotate outwards towards the pool robot, the first frame, or the first body to open the third opening.

[0097] When the first filter cartridge is outside the pool robot, the first bottom cover has an operating state with the third opening open and a non-operating state with the third opening closed. For example, after the first filter cartridge is removed from the pool robot, the user can manually open or close the first bottom cover according to their needs to manually clean the debris. Furthermore, during or after the first filter cartridge is removed from the pool robot, the first bottom cover remains in a non-operating state until the user applies any pressure to it, preventing debris from falling out through the third opening during or after the removal of the filter cartridge. After the first filter cartridge is removed, the third opening of the first bottom cover can only be opened by the user applying pressure to it.

[0098] In the above embodiments, the first filter box has a first state and a second state; in the first state, the first filter box is installed inside the first main body; in this first state, the pool robot is in the pool, and the first bottom cover closes the third opening; or, in this first state, the pool robot is parked on the base station, and the first bottom cover at least opens the third opening so that the waste in the first filter box can be discharged from the first main body through the third opening; in the second state, the first filter box is located outside the first main body; in this second state, the first bottom cover can open and close the third opening; and, during the transition from the first state to the second state, the first bottom cover keeps the third opening closed.

[0099] In some embodiments, such as Figures 1 to 4 , Figure 8 , Figure 11 As shown, at least a portion of the third opening is located on the bottom of the first filter box, facilitating the rapid discharge of waste and liquid inside the first filter box out of the first filter box under the influence of gravity. For example, in some embodiments, the bottom of the first filter box has a bottom opening, which serves as the third opening, and a first bottom cover is movably disposed on the third opening to open or close the third opening.

[0100] When the pool robot stops on the base station, the first bottom cover opens the third opening, which connects to the third inlet of the second filter box on the base station. This allows debris and liquid in the first filter box to drain from the third opening and fall into the second filter box through the third inlet. For example, during the cleaning of the first filter box, the first nozzle 2173 sprays liquid (such as water or cleaning solution) into the first filter box 1051, washing away debris adhering to the inner wall and filter screen. Under the combined action of gravity and the impact of the water flow, the washed-down debris and rinsing liquid pass through the third opening and the third inlet in sequence, eventually falling into and being collected in the second filter box of the base station.

[0101] For example, in some embodiments, when the pool robot is stationary on the base station, at least a portion of the first filter box is located above at least a portion of the second filter box, or at least a portion of the first filter chamber of the first filter box is located above at least a portion of the second filter chamber; when the third opening is open, the waste and liquid in the first filter box are discharged from the first filter box through the third opening under the influence of gravity, and fall into the second filter box through the third inlet. Alternatively, in other embodiments, when the pool robot is stationary on the base station, 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 waste and liquid in the first filter box quickly fall into the second filter box under the influence of gravity. Alternatively, in other embodiments, when the pool robot is stationary on the base station, along the height direction of the base station, the projection of the third opening on the horizontal plane completely falls within the projection of the third inlet on the horizontal plane, or the two completely overlap, to ensure that all waste can enter the second filter box.

[0102] It should be noted that: the bottom of the first filter box being exposed above the first main body or communicating with the outside means that after the third opening is closed by the first bottom cover; the bottom wall of the first bottom cover is flush with the bottom wall of the first main body; or the bottom wall of the first bottom cover protrudes downward beyond the bottom wall of the first main body (i.e., in the height direction of the pool robot, the bottom wall of the first bottom cover is lower than the bottom wall of the first main body); or the bottom wall of the first bottom cover is recessed relative to the bottom wall of the first main body (i.e., in the height direction of the pool robot, the bottom wall of the first bottom cover is higher than the bottom wall of the first main body).

[0103] In other words, when the third opening is closed by the first bottom cover, the user can see the bottom wall of the first bottom cover from the bottom of the pool robot. The bottom wall of the first bottom cover, as part of the bottom wall of the pool robot, is exposed to the external environment. The bottom wall of the pool robot includes at least the bottom wall of the bottom shell, the bottom wall of the first bottom cover, the walking surface of the walking mechanism (e.g., the walking surface of the track), the bottom wall of the main roller brush, etc.

[0104] In some embodiments, such as Figures 11 to 15As shown, 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.

[0105] For example, at least one opening is present on at least one side wall of the first frame, and a first filter screen is disposed at this opening to form a filter surface; in other embodiments, in addition to the first filter screen being disposed on the side wall, the first frame may also be disposed on at least one of the top and bottom of the first frame to form a filter surface. In some embodiments, the material of the first filter screen may be non-woven fabric, nylon, filter cotton, or other materials with filter pores.

[0106] In some embodiments, such as Figure 9 As shown, the bottom of the first main body is provided with a seventh opening 1033. In some embodiments, at least a portion of the third opening is located above at least a portion of the seventh opening in the height direction of the pool robot. When the first bottom cover opens the third opening, the waste in the first filter box is discharged out of the pool robot sequentially through the third opening and the seventh opening. In this embodiment, the seventh opening not only allows the waste to be discharged out of the pool robot, but also needs to avoid the movement of the first bottom cover; that is, the seventh opening serves as the first drain outlet for the waste in the first filter box to be discharged out of the pool robot. For example, the first bottom cover is rotatably disposed at the third opening, and the seventh opening needs to avoid the rotation of the first bottom cover. Specifically, the first bottom cover rotates outward toward the first main body through the seventh opening to open the third opening; or, the first bottom cover rotates toward the third opening through the seventh opening to close the third opening.

[0107] In other embodiments, the seventh opening is located above the third opening, or flush with the third opening. When the first bottom cover opens the third opening, the waste in the first filter box is directly discharged from the pool robot through the third opening. In this case, the seventh opening mainly serves to allow the first bottom cover to rotate and expose the first bottom cover to the external environment when the third opening is closed; or it exposes the third opening to the external environment when the first bottom cover opens. For example, the first bottom cover rotates below the seventh opening to open or close the third opening. In this embodiment, the third opening serves as the first discharge outlet for waste in the first filter box to be discharged from the pool robot.

[0108] The first bottom cover 1054 can move in several ways: In some embodiments, the first bottom cover 1054 is rotatably mounted on the first frame 1053. For example, the first bottom cover opens the third opening 10531 by rotating inward into the first frame; conversely, the third opening is closed when the first bottom cover rotates from inside the first frame towards the third opening. In this embodiment, when the first bottom cover opens the third opening, some debris is blocked inside the first frame because the first bottom cover rotates into the inner cavity of the first filter box, making it difficult to discharge from the first filter box through the third opening. Therefore, in other embodiments, the first bottom cover opens the third opening by rotating outward from the first frame, outward from the pool robot, or outward from the first body; conversely, the third opening is closed when the first bottom cover rotates from outside the first frame towards the third opening. In this embodiment, when the third opening is open, since the first bottom cover is outside the first frame, it does not block debris inside the first filter box, allowing debris to be discharged from the first filter box through the third opening, thereby improving the cleaning effect of the sprayed liquid from the first nozzle on the first filter box.

[0109] Furthermore, in some embodiments, the base station body includes a third receiving cavity, and at least one fourth opening is disposed on the base station body and communicates with the third receiving cavity; at least a portion of the second filter box is disposed in the third receiving cavity; the fourth opening and the third inlet are communicated; when the pool robot stops on the base station body and the first bottom cover rotates outward toward the pool robot to open the third opening, at least a portion of the first bottom cover engages with the fourth opening, so that the garbage in the first filter box falls sequentially from the third opening, the fourth opening, and the third inlet into the second filter box.

[0110] In another embodiment, the first bottom cover 1054 is slidably disposed on the first frame 1053, opening or closing the third opening 10531 by sliding above the third inlet 21101 and / or the fourth opening; or, the first bottom cover is slidably disposed on the first frame, opening or closing the third opening by sliding below the third inlet and / or the fourth opening. For example, in some embodiments, the first bottom cover is slidably disposed on the first frame, and when the pool robot stops on the base station body, the first bottom cover slides above the third inlet of the second filter box to open or close the third opening. In other embodiments, if the base station includes a third receiving cavity, at least a portion of the second filter box is disposed within the third receiving cavity; when the pool robot stops on the base station body, the first bottom cover slides above the fourth opening of the third receiving cavity to open or close the third opening. When the third opening is open, waste and liquid in the first filter box enter the second filter box sequentially through the third opening, the seventh opening, the fourth opening, and the third inlet; or, waste and liquid in the first filter box enter the second filter box sequentially through the third opening, the fourth opening, and the third inlet. Furthermore, in some embodiments, the first bottom cover is positioned above the third inlet and is horizontally slidable at the third opening.

[0111] For the first filter chamber, the first filter chamber is a receiving cavity formed by at least the first frame, the first filter screen, and the first bottom cover. Similarly, the second filter chamber is a receiving cavity formed by at least the second frame, the second filter screen, and the bottom of the second filter box.

[0112] When the pool robot stops at the base station to clean the first filter box, based on the positional relationship between the first filter box 1051, the third receiving cavity 2054, and the second filter box 21102, the following multiple implementation methods are provided: Implementation method 1: The first frame or first filter chamber of the first filter box is located outside the second filter box and / or the third receiving chamber.

[0113] like Figure 3 As shown, when the pool robot stops on the base station to clean the first filter box, the first frame 1053 or the first filter cavity of the first filter box remains within the first main body 1001. That is, the first frame will not extend beyond the first main body and is located outside the third receiving cavity 2054 or the second filter box 21102. It should be noted that at this time, the first frame is located outside the third receiving cavity and the second filter box of the base station, and they are not nested together. The first bottom cover 1054 moves relative to the first frame 1053 to open or close the third opening 10531.

[0114] like Figure 1 , Figure 4As shown, when the first bottom cover 1054 opens the third opening 10531 (i.e., the first bottom cover is in the unlocked state), at least a portion of the first bottom cover 1054 extends into the third receiving cavity 2054 or the second filter box 21102. Alternatively, at least a portion of the first bottom cover 1054 extends into both the third receiving cavity 2054 and the second filter box 21102 simultaneously. Alternatively, the entire first bottom cover 1054 remains outside the third receiving cavity 2054 or the second filter box 21102.

[0115] like Figure 2 , Figure 3 As shown, when the first bottom cover 1054 closes the third opening 10531 (i.e., the first bottom cover is in a locked state), the first filter chamber of the first filter box is located outside the second filter chamber and the third receiving chamber 2054 of the second filter box 21102. In other words, the first filter chamber is located outside the second filter chamber and the third receiving chamber, and they are not nested together.

[0116] In other words, when the pool robot stops at the base station to clean the first filter box, regardless of whether the first bottom cover opens the third opening, the first frame remains inside the first filter chamber and outside the third receiving chamber or the second filter box, and they are not nested together.

[0117] Implementation Method 2: At least a portion of the first frame or the first filter cavity of the first filter box is located within the second filter box and / or the third receiving cavity.

[0118] When the pool robot stops at the base station to clean the first filter box, at least a portion of the first frame 1053 extends from the first body and into the third receiving cavity 2054 or the second filter box 21102. The first bottom cover 1054 moves relative to the first frame 1053 to open or close the third opening 10531.

[0119] When the first bottom cover 1054 opens the third opening 10531 (i.e., the first bottom cover is in the unlocked state), at least a portion of the first bottom cover extends into the third receiving cavity or the second filter box, for example, the entire first bottom cover extends into the third receiving cavity or the second filter box. Alternatively, at least a portion of the first bottom cover extends into both the third receiving cavity and the second filter box simultaneously, for example, the entire first bottom cover extends into both the third receiving cavity and the second filter box simultaneously.

[0120] In some embodiments, such as Figure 11 As shown, the first bottom cover includes a first mounting portion 1054a and a first movable portion 1054b. The first mounting portion is rotatably mounted on the first frame via a first rotating shaft 1054c, and the first movable portion rotates around the first rotating shaft to open or close the third opening. When the first bottom cover opens to reveal the third opening, there are various embodiments for the engagement of at least a portion of the first bottom cover with the fourth opening.

[0121] For example, in some embodiments, the first movable portion of the first bottom cover is close to or near the fourth opening and is located above the fourth opening, and a gap may exist between the first movable portion of the first bottom cover and the fourth opening; or, in other embodiments, the first movable portion of the first bottom cover abuts against the top of the fourth opening to shorten the distance between the third and fourth openings, shortening the path for the waste in the first filter box to fall into the second filter box, facilitating the rapid fall of the waste in the first filter box into the second filter box. Or, in other embodiments, to further shorten the distance between the third and fourth openings, the first movable portion extends into the fourth opening; or, the first movable portion extends through the fourth opening into the second filter box. That is, at least a portion of the first bottom cover extends into the fourth opening or at least a portion extends into the second filter box. In this embodiment, the fourth opening not only serves to allow waste to flow through, but also needs to avoid the rotation of the first bottom cover so that the first movable portion of the first bottom cover can rotate into the fourth opening or the second filter box. That is, when the first bottom cover and the fourth opening are aligned, the first frame remains within the first receiving cavity of the pool robot.

[0122] In some embodiments, the base station body includes a second filter box. When the first bottom cover rotates outward from the first body to open the third opening, at least a portion of the first bottom cover engages with the third inlet of the second filter box, thereby shortening the distance between the third opening and the third inlet, facilitating the rapid fall of waste and liquid from the first filter box into the second filter box. Similar to the aforementioned embodiments, there are various ways to engage at least a portion of the first bottom cover with the third inlet of the second filter box. For example, in some embodiments, the first movable part is close to or adjacent to the third inlet and located above the third inlet, with a gap between the first movable part and the third inlet; or, the first movable part abuts against the top of the third inlet, or the first movable part extends into the third inlet, or extends through the third inlet into the second filter box. That is, when the first bottom cover and the third opening are engaged, the first frame remains within the first receiving cavity of the pool robot.

[0123] Alternatively, in other embodiments, when the first bottom cover opens the third opening, the first bottom cover is entirely located within the third receiving cavity or the second filter box (because the first frame extends into the interior of the third receiving cavity or the second filter box).

[0124] To enable the switching of the first bottom cover between different states (i.e., opening the third opening and closing the third opening), in some embodiments, the pool robot further includes a fourth drive component; in the first state, the pool robot is stationary on the base station, and the fourth drive component is used at least to drive the first bottom cover to move to open the third opening. Furthermore, in some embodiments, the fourth drive component includes at least a fourth drive element, which may be a motor, cylinder, etc.

[0125] For example, in one embodiment, the fourth driving element is a fourth motor 105923, which is located inside the first body. The fourth motor is used at least to open the first bottom cover so that when cleaning the first filter box, the first bottom cover can be automatically driven to move to open the third opening.

[0126] Furthermore, in some embodiments, in the first state, the pool robot is stationary on the base station, and the fourth drive component is at least also used to drive the first bottom cover to close the third opening. Alternatively, in other embodiments, in the first state, the pool robot is stationary on the base station, and the third opening is closed by the user manually driving the first bottom cover to close the third opening.

[0127] In some embodiments, the fourth drive assembly further includes at least one third transmission member connected to the first bottom cover; in the first state, the pool robot is stationary on the base station, and the fourth drive assembly is used at least to drive the third transmission member to move, thereby driving the first bottom cover to move and open the third opening.

[0128] For example, in some embodiments, the fourth driving member is disposed within the first body; in the first state, the fourth driving member establishes a driving relationship with the third transmission member; in the second state, the fourth driving member disconnects from the third transmission member, and the third transmission member is located outside the first body along with the first filter box.

[0129] Furthermore, in some embodiments, in the second state, the third opening is closed by the user manually driving the first bottom cover to move.

[0130] In some embodiments, the fourth drive assembly further includes at least one second transmission member disposed within the first body and connected to the output shaft of the fourth drive member; and the second and third transmission members have a transmission state for establishing transmission and a separation state for disengaging transmission. When the first filter box is in the installation state, i.e., the first filter box is installed within the first body, the third and second transmission members are in the transmission state. At this time, the fourth drive member drives the second transmission member to move, drives the second transmission member to rotate, and drives the first bottom cover to rotate, so as to open or close the third opening; when the first filter box is removed from the first body, the second and third transmission members separate from each other to block the transmission path; or, in the first state, at least one second transmission member establishes a transmission relationship with at least one third transmission member; in the second state, the second and third transmission members separate.

[0131] For example, in some embodiments, when the first bottom cover is rotatably disposed on the first frame of the first filter box; at least one third transmission member is disposed on the rotating shaft of the first bottom cover so that the third transmission member is connected to the first bottom cover; in a first state, the third driving member drives the second transmission member to rotate so as to drive the third transmission member and the first bottom cover to rotate; in a second state, the second transmission member is separated from the third transmission member, and the third driving member cannot drive the third transmission member and the first bottom cover to rotate.

[0132] In one specific embodiment, such as Figure 12 As shown, the fourth driving component is a fourth motor 105923; the second transmission component is a third gear 105921, and the third transmission component is a fourth gear 105922; wherein, the fourth motor and the third gear are located within the first main body, with the third gear located on the output shaft of the fourth motor and the fourth gear located on the rotating shaft of the first bottom cover; in the transmission state, the third gear and the fourth gear mesh, and the fourth motor drives the third gear to rotate, thereby driving the fourth gear to rotate; in the disengagement state, the third gear and the fourth gear separate. Further, in some other embodiments, when the fourth motor drives the first bottom cover to rotate, the pool robot can also use the self-locking force of the fourth motor to keep the first bottom cover closed at the third opening. Alternatively, the self-locking force of the motor and the locking mechanism work together to lock the first bottom cover onto the first frame.

[0133] In other embodiments, a fourth drive assembly is disposed on the first filter box; in a first state, the first drive assembly is located inside the first body along with the first filter box; in a second state, the fourth drive assembly is located outside the first body along with the first filter box. For example, in some embodiments, the fourth drive component is a fourth motor, which is disposed on the first filter box, and the fourth motor is used at least to drive the first bottom cover to move to open the third opening.

[0134] For example, in some embodiments, the first bottom cover is rotatably mounted on the first frame of the first filter box; the fourth drive assembly drives the first bottom cover to rotate, switching between opening and closing the third opening. In this embodiment, a locking mechanism and an unlocking mechanism may be provided to further improve the accuracy of the first bottom cover in opening and closing the third opening; alternatively, the locking mechanism and unlocking mechanism may not be provided.

[0135] In some embodiments, in the second state, the fourth drive component drives the first bottom cover to move to switch between opening and closing the third opening; and / or, in the first state, the pool robot is stationary on the base station, and the fourth drive component drives the first bottom cover to move to switch between opening and closing the third opening.

[0136] Furthermore, in some embodiments, the fourth drive assembly further includes at least one clutch assembly to enable a third state in which the first bottom cover and the fourth motor rotate synchronously under the drive of the fourth motor; and a fourth state in which the first bottom cover rotates relative to the fourth motor under the action of an external driving force but not driven by the fourth motor. In this embodiment, in the second state, the user can manually drive the first bottom cover to open and close the third opening.

[0137] In some embodiments, the first bottom cover only needs to open the third opening when the waste in the first filter box needs to be discharged from the third opening. For example, when the pool robot is parked on the base station, and the first nozzle is cleaning the first filter box, it needs to discharge the waste in the first filter box into the second filter box of the base station, which requires the first bottom cover to open the third opening; or, for example, after the user removes the first filter box from the pool robot, the user manually operates the first bottom cover to open the third opening.

[0138] When the pool robot is in the pool, or on the shore and does not need to discharge waste from the first filter box through the third opening, the first bottom cover is in a closed third opening state. For example, when the pool robot is performing cleaning in the pool, the first filter box is in the first receiving cavity, and the first bottom cover always keeps the third opening closed so that the waste in the first filter box 1051 will not be discharged from the third opening, thus not affecting the pool robot's cleaning of the pool bottom, pool walls, waterline, or water surface. Alternatively, when the pool robot is on the shore, it may or may not be on the base station, but it is not in the process of the first nozzle cleaning the first filter box. If the user wants to remove the first filter box 1051 from the first body 1001, to ensure that the first bottom cover remains closed during or after the user removes the first filter box, and before the user manually opens the first bottom cover, the third opening is kept closed to prevent the waste in the first filter box 1051 from falling out through the third opening.

[0139] Therefore, in some embodiments, the first bottom cover has a locked state and an unlocked state. When the first bottom cover is in the locked state, it is locked to the first frame, keeping the third opening closed. When the first bottom cover is in the unlocked state, it can move relative to the first frame to open or close the third opening. For example, the first bottom cover is in the locked state when the pool robot is inside the pool cleaning the pool liquid or when the pool robot is outside the pool not cleaning the first filter box; the first bottom cover is in the unlocked state when the pool robot is on or off the base station body cleaning the first filter box.

[0140] In some embodiments, such as Figures 14 to 17As shown, the pool robot also includes a locking mechanism 1080, which is used to lock the first bottom cover to the first frame or the side wall of the first filter box so that the first bottom cover remains closed at the third opening; before the first bottom cover opens the third opening, the locking mechanism first releases the lock on the first bottom cover.

[0141] Correspondingly, in some embodiments, such as Figures 13 to 15 , Figures 17 to 18 , Figure 22 , Figure 26 , Figure 31 , Figure 35 , Figure 39 As shown, the pool robot or base station body is equipped with an unlocking mechanism 7003, which is used to unlock the locking mechanism 1080 from locking the first bottom cover. Alternatively, in some other embodiments, in the second state, the locking mechanism is manually operated by the user to unlock the first bottom cover.

[0142] When the first bottom cover is rotatably mounted on the first frame, in some embodiments, in a first state, the pool robot is stationary on the base station, and after the locking mechanism releases the lock on the first bottom cover, the first bottom cover rotates under its own weight and / or the weight of the debris in the first filter box to open the third opening; and / or, in a second state, after the locking mechanism releases the lock on the first bottom cover, the first bottom cover rotates under its own weight and / or the weight of the debris in the first filter box to open the third opening.

[0143] Furthermore, in some embodiments, during the process of the first filter box switching from the first state to the second state, the first bottom cover is kept closed by the locking mechanism to keep the third opening closed.

[0144] There are various implementations for the locking mechanism. For example, in some embodiments, the locking mechanism locks the first bottom cover to the first frame by magnetic attraction. Alternatively, in other embodiments, the locking mechanism locks the first bottom cover to the first frame by a snap-fit ​​structure. Or, in still other embodiments, the locking mechanism locks the first bottom cover to the first frame by the self-locking force of a motor.

[0145] In other embodiments, such as Figures 14 to 17 As shown, the locking mechanism locks the first bottom cover onto the first frame by extending; correspondingly, the unlocking mechanism drives the locking mechanism to retract, thereby releasing the locking mechanism from locking the first bottom cover, allowing the first bottom cover to move relative to the first frame to open or close the third opening.

[0146] In some embodiments, such as Figure 14 , Figure 16 and Figure 17As shown, the locking mechanism includes at least one first limiting portion and at least one first locking member 10802. The first locking member is slidably disposed relative to the first limiting portion, and one of the first locking member and the first limiting portion is disposed on the first bottom cover, while the other is disposed on the first frame. In the locked state, the locking portion of the first locking member extends into the first limiting portion; in the unlocked state, the locking portion of the first locking member retracts from the first limiting portion and separates from it. Correspondingly, the unlocking mechanism is used to drive the first locking member to retract and move back to exit the first limiting hole.

[0147] Furthermore, such as Figure 14 and Figure 17 As shown, the locking mechanism further includes at least one fourth elastic element 10803, which is connected to the first locking element. The fourth elastic element applies a first biasing force, a first preload, or a first elastic force to the first locking element, forcing the locking portion of the first locking element to tend to remain within the first limiting portion.

[0148] For example, such as Figure 14 and Figure 17 As shown, the first limiting part includes at least a first limiting hole 10801, one of the first locking member and the first limiting hole is provided on the first frame, and the other is provided on the first bottom cover; the fourth elastic member applies its elastic force to the first locking member, forcing the first locking member to tend to extend, so as to remain in the first limiting hole and lock the first bottom cover on the first frame; correspondingly, the unlocking mechanism is used to drive the first locking member to retract and move to exit the first limiting hole.

[0149] For example, such as Figure 14 and Figure 17 As shown, the first limiting hole 10801 is provided on the first frame, and the first locking member is telescopically or slidably provided on the first bottom cover. The first locking member has a locking part 108021 and a first mounting end 108022. The fourth elastic member is a compression spring, one end of which is provided on the first mounting end of the first locking member, and the other end is provided on the first bottom cover. The compression spring applies a first elastic force to the first locking member in the direction of the first limiting hole, causing the locking part of the first locking member to tend to extend out of the first bottom cover and into the first limiting hole, thereby locking the first bottom cover on the first frame, and keeping the first bottom cover closed with the third opening closed.

[0150] In some embodiments, the first mounting end of the first locking member is disposed inside the first bottom cover, and the locking portion can extend out of the first bottom cover and into the first limiting hole. For example, as... Figure 14As shown, the first bottom cover includes a first mounting cavity 1054d, the first mounting end of the first locking member is disposed in the first mounting cavity, the fourth elastic member is disposed in the first mounting cavity, the first bottom cover is provided with a first sliding hole 10804, and the locking part of the first locking member is located outside the first bottom cover through the first sliding hole; or, the first locking member is slidably disposed on the first sliding hole, the first mounting end of the first locking member is located in the first mounting cavity, and the locking part of the first locking member is located outside the first bottom cover.

[0151] Furthermore, in other embodiments, because the fourth elastic member applies a biasing force toward the outside of the first locking member towards the first bottom cover, in order to prevent the first locking member from sliding outward from the first bottom cover and disengaging from the first bottom cover, such as... Figure 17 As shown, the locking mechanism further includes a first limiting component, which is disposed on the first bottom cover and is used to block the first locking member on the first bottom cover. For example, in some embodiments, the first limiting component includes a second sliding hole 10805 and a first limiting member 10806, wherein the first limiting member is fixedly or detachably connected to the first locking member, the second sliding hole is disposed on the first bottom cover, and the second sliding hole and the first sliding hole are staggered in the horizontal or vertical direction. The first limiting member moves synchronously with the first locking member and slides in the second sliding hole, thereby limiting the first locking member on the first bottom cover.

[0152] In other embodiments, after the first filter cartridge is removed from the pool robot, the user can press the first limiting member to drive the first locking member to retract, thus manually releasing the first locking member from locking the first bottom cover. This allows the first bottom cover to move, opening the third opening, or the user can manually close the first bottom cover to the third opening. Further, a button is provided at one end of the first limiting member, allowing the user to unlock the first bottom cover by pressing the button. Alternatively, in other embodiments, the user can also directly press the first locking member to retract, manually releasing the first locking member from locking the first bottom cover. In this embodiment, the locking mechanism may or may not include the first limiting component.

[0153] In some embodiments, in a first state, the pool robot is stationary on a base station. The pool robot also includes an unlocking mechanism, which, when driven by the unlocking mechanism, releases the lock on the first bottom cover.

[0154] For example, in some embodiments, the unlocking mechanism is used to drive the first locking member to move, thereby releasing the first locking member from locking the first bottom cover. In some embodiments, such as Figures 13 to 15 , Figure 17As shown, the unlocking mechanism includes at least one first driving component and at least one unlocking component 7003. The first driving component includes at least one first driving member, and the unlocking component includes at least one second unlocking member 70033. The first driving member is at least used to drive the second unlocking member to move, thereby driving the first locking member to move and causing the first locking member to release the first bottom cover from its lock. For example, the first driving member is at least used to drive the second unlocking member to move, so that at least a portion of the second unlocking member extends into the first limiting portion, thereby pushing the locking portion out of the first limiting portion.

[0155] For example, in some embodiments, the first driving member is a first motor 70035, which drives the second unlocking member to extend or rotate, so that at least a portion of the second unlocking member extends into the first limiting portion, thereby pushing the locking portion out of the first limiting portion. Alternatively, in other embodiments, the first driving member directly drives the first locking member to retract, so as to exit the first limiting hole. For example, the first driving member is a cylinder, which drives the first locking member to retract, so as to exit the first limiting hole.

[0156] In some embodiments, in a first state, the pool robot is stationary on the base station, and the locking mechanism is released from the lock on the first bottom cover by the drive of the unlocking mechanism on the base station.

[0157] For example, in some embodiments, such as Figures 18 to 43 As shown, the unlocking component 7003 also includes at least one first unlocking member 70037 disposed on the base station body. A first motor is disposed on the base station, and the first motor drives at least the first unlocking member to move, so that the first unlocking member drives the second unlocking member to move, thereby causing at least a portion of the second unlocking member to extend into the first limiting portion, thereby pushing the first locking member to retract, and the first locking member to exit the first limiting hole, thereby unlocking the first bottom cover.

[0158] Furthermore, in some embodiments, at least a portion of the unlocking component is disposed within the base station body. For example, as shown in the figure, at least a portion of the unlocking component is disposed within the sixth receiving cavity. For example, the first motor is disposed within the sixth receiving cavity; at least a portion of the first unlocking member is disposed within the sixth receiving cavity. Furthermore, the two first motors are distributed on both sides of the fourth opening.

[0159] Furthermore, in some embodiments, at least part of the unlocking components are disposed on the mounting plate. For example, a first motor is disposed on the mounting plate; furthermore, two first motors are symmetrically disposed on opposite sides of the fourth opening.

[0160] In some embodiments, the mounting plate is provided with a second mounting portion 200020, and at least part of the unlocking mechanism is disposed in the second mounting portion, for example, the first motor is disposed in the second mounting portion.

[0161] In other embodiments, after the first bottom cover is unlocked, its rotation is not driven by a motor, but by its own weight; or, the weight of the first bottom cover combined with the weight of the waste and liquid inside the first filter box drives its rotation to open the third opening. When the first bottom cover needs to close the third opening, its closure requires a motor. For example, a closing mechanism within the base station or the first main body can be used to drive the rotation of the first bottom cover to close the third opening.

[0162] In some embodiments, such as Figures 22 to 43 As shown, the base station also includes at least one closing mechanism, which is located on the base station body. The closing mechanism drives the first bottom cover of the first filter box to rotate toward the third opening, thereby closing the third opening. After the liquid sprayed by the first nozzle has cleaned the first filter box, the closing mechanism drives the first bottom cover to rotate and close the third opening. That is, the closing mechanism switches the first bottom cover from an open third opening state to a closed third opening state. Alternatively, in the first state, the pool robot is stationary on the base station, and the closing mechanism on the base station drives the first bottom cover to move, causing the first bottom cover to close the third opening.

[0163] In some embodiments, such as Figures 22 to 43 As shown, the closing mechanism 7004 includes at least a third drive assembly and at least one push assembly. The third drive assembly includes at least one third drive member, and the push assembly includes at least one first push member. The third drive member drives the first push member to perform telescopic movements, switching the first push member between an extended state and a retracted state. When the first nozzle sprays liquid to clean the first filter box, the first push member is in a retracted state to avoid the first bottom cover. After the liquid sprayed by the first nozzle cleans the first filter box, the first push member switches from the retracted state to the extended state to push the first bottom cover to rotate toward the third opening, thereby closing the third opening. After the first bottom cover closes the third opening, the first push member switches back from the extended state to the retracted state. For example, the third drive member can be a third motor 70042 or a cylinder.

[0164] For example, in some embodiments, the pushing component is a push rod assembly, which includes at least one push rod 70041. The push rod includes a third mounting end and a pushing portion, wherein the third mounting end is connected to a motor drive, and the pushing portion is used to push the first bottom cover to rotate toward the third opening. The motor drives the push rod to extend, causing the pushing portion to abut against the first bottom cover, thereby pushing the first bottom cover to rotate toward the third opening and closing the third opening.

[0165] In one embodiment, such as Figures 1 to 4As shown, when the pool robot stops at the cleaning position of the base station body, when the first bottom cover closes the third opening, the closing mechanism is located below the first bottom cover; when the first bottom cover opens the third opening, the closing mechanism is located on one side of the first bottom cover, so as to avoid the first bottom cover while allowing the closing mechanism to subsequently push the first bottom cover to close the third opening; or, when the first bottom cover opens the third opening, the closing mechanism is located below the first bottom cover. In this embodiment, the closing mechanism is always located below the first bottom cover, so that the push rod can push the first bottom cover from bottom to top to close the third opening.

[0166] In some embodiments, the pool robot rests on the base station body. When the first bottom cover opens the third opening, at least a portion of the first bottom cover extends into or through the fourth opening into the second filter box. When the pushing component is in the retracted state, it has at least two embodiments. For example, in some embodiments, the pushing component avoids or is not located within the fourth opening to avoid interfering with the opening of the first bottom cover. In other embodiments, at least a portion of the pushing component is located within the fourth opening; when the first bottom cover opens the third opening, at least a portion of the pushing component (e.g., the aforementioned pushing part) approaches or contacts the first bottom cover; or a clearance groove is provided on the bottom of the first bottom cover, and at least a portion of the pushing component (e.g., the pushing part) is located within the clearance groove, but the pushing component (e.g., the pushing part) does not impact the first bottom cover. Therefore, when the pushing component is in the retracted state, it does not interfere with the first bottom cover.

[0167] When the pushing component is in the extended state, at least a portion of the pushing component (e.g., the pushing part) is located within the fourth opening, or at least a portion of the pushing component (e.g., the pushing part) extends through the fourth opening and above the fourth opening to push the first bottom cover to rotate toward the third opening, thereby closing the third opening. Alternatively, in the height direction of the base station, the first projection of the pushing component on the horizontal plane intersects with the first projection of the first bottom cover on the horizontal plane.

[0168] In some embodiments, at least a portion of the closing mechanism is disposed within the base station body; for example, the base station body further includes a sixth receiving cavity. At least a portion of the pushing component is disposed within the sixth receiving cavity, and this portion extends out of the sixth receiving cavity to push the first bottom cover to move; or at least a portion of the pushing component retracts into the sixth receiving cavity to reset to a retracted state. For example, a third driving member is disposed within the sixth receiving cavity for driving the pushing component to perform a telescopic movement. In one embodiment, the third driving member is disposed on one side of the fourth opening. For example, the third driving member is disposed within the sixth receiving cavity and on one side of the fourth opening. In other embodiments, the at least partially closing mechanism is further away from the first nozzle than the at least partially fourth opening.

[0169] Furthermore, in some embodiments, at least a portion of the sixth receiving cavity is located above the second filter box or at least a portion of the sixth receiving cavity is located above the third receiving cavity. The closing mechanism is disposed in the sixth receiving cavity. The extension and retraction movement of the closing mechanism will not affect the garbage in the second filter box, nor will it affect the user's ability to pull the second filter box in the third receiving cavity, thereby making the structure on the base station compact. At the same time, when the pushing component is in the retracted state, the pushing component will not interfere with the first bottom cover.

[0170] In other embodiments, such as Figures 18 to 43 As shown, the base station body includes at least one mounting plate 200013, which is disposed within the inner cavity of the base station body. Along the height direction of the base station body, the mounting plate divides the inner cavity of the base station body into at least a sixth receiving cavity and a third receiving cavity, with at least a portion of the sixth receiving cavity located above the third receiving cavity. Correspondingly, a portion of the fourth opening (i.e., a contaminant inlet channel) is disposed on the second upper shell at the top of the base station body, and a portion of the fourth opening is disposed on the mounting plate to form an opening with a certain height or thickness. For example, in some embodiments, a mounting step is provided inside the second dust chamber, and the mounting plate is disposed on the mounting step to house the mounting plate within the cavity.

[0171] In one embodiment, at least a partial closing mechanism is disposed on the mounting plate. For example, such as... Figures 23 to 43 As shown, the third motor is mounted on the mounting plate; further, in some embodiments, the third motor is located on one side of the fourth opening and further away from the fourth opening than the pushing component; further, the third motor is further away from the first nozzle than the fourth opening.

[0172] In some embodiments, such as Figure 24 , Figure 29 , Figure 33 , Figure 37 , Figure 42 As shown, the mounting plate is provided with a fourth mounting part 200017, and at least a partial closing mechanism is provided in the fourth mounting part, for example, a third motor is provided in the fourth mounting part.

[0173] Alternatively, in other embodiments, the closing mechanism is located within the first body. For example, the third drive assembly includes a third drive member and at least one of the aforementioned third transmission members, connected to the first bottom cover. In the first state, the pool robot is stationary on the base station, and the third drive member is used at least to drive the third transmission member to move, thereby driving the first bottom cover to close the third opening.

[0174] Furthermore, the third drive assembly also includes at least one of the aforementioned second transmission members, disposed within the first main body, and the second transmission member is connected to the output shaft of the third drive member. In the first state, at least one second transmission member establishes a transmission relationship with at least one third transmission member, the pool robot stops on the base station, and the third drive member is used at least to drive the third transmission member to move, thereby driving the first bottom cover to move and close the third opening. In the second state, the second transmission member and the third transmission member are separated. In this embodiment, the third drive member and the fourth drive member are the same drive member, for example, the fourth motor and the third motor are the same motor.

[0175] When the pool robot stops on the base station and the first nozzle cleans the first filter box, the base station activates the unlocking mechanism to drive the locking mechanism to retract, thus releasing the locking mechanism from locking the first bottom cover. In the unlocked state, the first bottom cover automatically moves outwards from the pool robot under its own weight and / or the weight of the debris and liquid inside the first filter box, thereby opening the third opening and allowing the debris and liquid inside the first filter box to fall naturally and be automatically discharged. Alternatively, when the first nozzle cleans the first filter box, the fourth motor starts, driving the first bottom cover outwards from the pool robot, thereby opening the third opening. After cleaning is complete, the closing mechanism on the base station activates, actively or passively driving the first bottom cover to rotate towards the third opening to close it. Alternatively, the fourth motor starts, driving the first bottom cover inwards from the pool robot, thereby closing the third opening.

[0176] When the pool robot is not on the base station or at least part of the pool robot is off the resting surface, the user can manually unlock and close the first bottom cover. When manual cleaning is required, the user can remove the first filter box from the first body through the access port. During this process, the first bottom cover remains in a non-working state to prevent leakage of waste during disassembly or handling. After the first filter box is completely removed, the user can press the first locking member, the first limiting member, or the button to drive the first locking member to retract, thus manually releasing the first locking member from locking the first bottom cover. This allows the first bottom cover to move relative to the first frame to a working state under its own weight and / or the weight of the waste and liquid inside the first filter box, so that the internal waste and impurities can be manually emptied or rinsed. After cleaning is complete, the user can manually close the first bottom cover to reset the locking mechanism, keeping the first bottom cover in a non-working state.

[0177] It should be noted that for a swimming pool robot to stop on a base station, the walking surface of its tracks must be in contact with the resting surface. If the walking surface of the tracks is not in contact with the resting surface, the swimming pool robot is considered not to have stopped on the base station, or if it has stopped at the designated position on the base station.

[0178] In some embodiments, since the waste and liquid in the first filter box enter the second filter box through the third opening, the fourth opening, and the third inlet, the waste in the second filter box tends to accumulate at or below the fourth opening. The waste accumulated at the fourth opening makes it difficult for the waste in the first filter box to fall into the second filter box.

[0179] Therefore, in some embodiments, such as Figures 18 to 43 As shown, the base station also includes at least one actuating mechanism, which is movably disposed on the base station body. At least a portion of the actuating mechanism reciprocates within the second filter box to actuate the accumulated garbage within the second filter box, dispersing the garbage evenly within the inner cavity of the second filter box, improving the space utilization within the second filter box, preventing garbage from accumulating below the fourth opening, and ensuring that the garbage in the first filter box falls smoothly into the second filter box.

[0180] In some embodiments, such as Figures 18 to 43 As shown, the agitating mechanism includes a second drive assembly and an agitating assembly. The agitating assembly includes at least one agitating element, and the second drive assembly includes at least one second drive element. The second drive element is used to drive the agitating element to reciprocate and / or reciprocate within the second filter box, enabling the agitating element to agitate the debris and facilitate rapid leveling of the debris. For example, the agitating element has at least a fifth position and a fourth position, and the second drive element is at least used to drive the agitating element to reciprocate and / or reciprocate between the fifth position and the fourth position to agitate the debris. In some embodiments, the second drive element can be a motor or a cylinder.

[0181] In one specific embodiment, such as Figures 18 to 43 As shown, the actuating mechanism is a lever mechanism 7006, the actuating assembly can be a lever assembly, the actuating element can be a lever 70062, and the second driving element is a second motor 70067. The lever is connected to the second motor, and the second motor drives the lever to reciprocate and / or reciprocate within the second filter box to actuate the debris. In another embodiment, the actuating element can be a non-lever-shaped structure, such as a plate-like structure or a mesh structure.

[0182] In some embodiments, such as Figures 1 to 4 As shown, when the pool robot is stationary on the base station, and the first bottom cover 1054 closes the third opening 10531, the first bottom cover 1054 is positioned above the lever assembly. When the first bottom cover 1054 opens the third opening 10531, at least a portion of the lever assembly moves below the first bottom cover 1054 to avoid interfering with the movement of the first bottom cover. For example, the lever moves below the fourth opening to move trash; furthermore, the lever moves the trash below the fourth opening and always below the first bottom cover to prevent the movement of the lever from interfering with the first bottom cover when it is open.

[0183] Furthermore, in some embodiments, when the pool robot stops on the base station body and the first bottom cover opens the third opening, at least a portion of the first bottom cover extends into the second filter box through the fourth opening. At this time, the movement of the lever mechanism will not interfere with the rotation of the first bottom cover.

[0184] In some embodiments, such as Figures 31 to 43 As shown, there are two lever mechanisms, symmetrically arranged on the base station body. Further, in one embodiment, each lever is driven by a second motor 70067; for example, the two second motors 70067 are distributed opposite each other along the length or width direction of the fourth opening. Alternatively, in another embodiment, as... Figures 18 to 30 As shown, there is one lever mechanism, and the actuating element is driven by two second motors 70067. For example, the two second motors 70067 are distributed relative to each other along the length or width direction of the fourth opening.

[0185] In some embodiments, at least a portion of the toggle assembly is disposed within the base station body. For example, at least a portion of the toggle assembly is disposed within the sixth receiving cavity. For example, the second motor is disposed within the sixth receiving cavity. Further, two second motors are distributed on either side of the fourth opening.

[0186] Furthermore, in some embodiments, at least part of the actuating mechanism is disposed on the mounting plate. For example, as... Figure 19 , Figure 23 , Figure 28 , Figure 32 and Figure 36 As shown, the second motor 70067 is mounted on the mounting plate; furthermore, the two second motors are symmetrically arranged on opposite sides of the fourth opening.

[0187] In some embodiments, the mounting plate is provided with a third mounting portion 200015, and at least part of the toggle assembly is disposed in the third mounting portion, for example, the second motor is disposed in the third mounting portion.

[0188] In another embodiment, such as Figure 19 , Figure 23 , Figure 28 , Figure 32 and Figure 36 As shown, the second motor is symmetrically arranged on the mounting plate and on opposite sides of the fourth opening, while the third motor is arranged on the other side of the fourth opening. That is, the two second motors and the third motor are respectively arranged on different sides of the fourth opening. In this embodiment, multiple motors are arranged around the fourth opening, so that the overall structure is tightly arranged, which can further reduce the size of the base station.

[0189] For example, in some embodiments, such as Figure 25 , Figure 30 , Figure 34 and Figure 38As shown, the bottom of the aforementioned mounting plate 200013 is provided with an upwardly recessed first clearance area 200013b and a second clearance area 200013c. Both the first and second clearance areas are located above the second filter box and are connected to the third receiving cavity. When the toggle is in the fourth position (e.g., the unlocked position), the toggle is located within the first clearance area and above the second filter box; when the toggle is in the fifth position (e.g., the initial position), the toggle is located within the second clearance area and above the second filter box, thus avoiding the pull-out path of the second filter box within the third receiving cavity.

[0190] like Figures 18 to 43 As shown, in some embodiments, to charge the pool robot, the base station further includes at least one charging component 2090, which charges the pool robot's first battery pack when the pool robot is stationary on the base station body. In some embodiments, the charging component can be a contact charging component or a contactless charging component (wireless charging). Contact charging components require direct physical contact between metal conductors to transfer electrical energy; contactless charging components (wireless charging) transfer energy through electromagnetic field coupling without physical contact.

[0191] Accordingly, the pool robot is equipped with at least one charging receiver 1020, which is electrically connected to the first battery pack. When the pool robot stops on the base station body, the charging component charges the first battery pack by contacting the charging receiver.

[0192] In some embodiments, the charging component includes at least one positive charging component and at least one negative charging component; the at least one positive charging component and at least one negative charging component are electrically connected; wherein, both the positive charging component and the negative charging component include at least one charging element 2091; the charging receiving component includes at least one positive receiving component and at least one negative receiving component; the at least one positive receiving component and at least one negative receiving component are electrically connected; wherein, both the positive receiving component and the negative receiving component include at least one charging element; when the positive charging component abuts against the negative receiving component, and the negative charging component abuts against the positive receiving component, the charging component charges the first battery pack.

[0193] In some embodiments, at least a portion of the charging components are disposed within the base station body. For example, at least a portion of the charging components are disposed within a sixth receiving cavity. For example, at least a portion of the first base is disposed within the sixth receiving cavity. Further, two first bases are disposed side-by-side on one side of the fourth opening. In other embodiments, at least a portion of the charging components are disposed further away from the first nozzle than the fourth opening.

[0194] In some embodiments, at least a portion of the charging components are disposed on the mounting plate. For example, such as Figure 19, Figure 23 , Figure 27 , Figure 32 , Figure 36 , Figure 41 As shown, the first seat is mounted on the mounting plate. Further, in one embodiment, two first seats are mounted on the mounting plate and arranged side-by-side on one side of the fourth opening; further, the two first seats are further away from the first nozzle than the fourth opening.

[0195] Furthermore, in some embodiments, the charging component and the closing mechanism are located on different sides of the fourth opening; or, in other embodiments, such as Figure 23 , Figure 27 , Figure 32 , Figure 36 , Figure 41 As shown, the charging component and the closing mechanism are located on the same side of the fourth opening; furthermore, the two charging components are distributed on both sides of the closing mechanism, for example, the two charging components are arranged side by side with a gap, and the closing mechanism is located between the two charging components, so that the closing mechanism and the charging components are staggered, so that the charging components do not affect the movement of the closing mechanism, and the overall structure is compact.

[0196] In some embodiments, such as Figure 23 , Figure 27 , Figure 32 , Figure 36 , Figure 41 As shown, the charging component and the closing mechanism are located on the same side of the fourth opening, with the closing mechanism closer to the fourth opening than the charging component. Alternatively, in some embodiments, at least a portion of the closing mechanism is closer to the first nozzle than at least a portion of the charging component.

[0197] In some embodiments, such as Figure 20 , Figure 24 , Figure 29 , Figure 33 , Figure 37 , Figure 42 As shown, the mounting plate is provided with a fifth mounting part 200014, and at least part of the charging components are disposed in the fifth mounting part, for example, the first base is disposed in the fifth mounting part.

[0198] Because the pool robot retrieves water from the pool and places it on the resting surface, or automatically returns to the resting surface from the pool, it inevitably carries liquid with it. When the pool robot passes by or stops at the charging position, the liquid it carries will drip onto the charging unit, affecting the charging of the charging receiver. For example, the charging unit may be electrolyzed by the liquid; or a short circuit may occur during the charging process.

[0199] Therefore, in some embodiments, the base station further includes a drying component 2800, which can provide ambient temperature air or hot air to at least dry the charging component, ensuring that the charging component is in a dry state; or, the drying component can also be used to dry both the charging component and the charging receiver simultaneously. For example, when the charging receiver at the bottom of the pool robot docks with the charging component, the drying component can dry both the charging component and the charging receiver simultaneously.

[0200] In some embodiments, such as Figures 18 to 43 As shown, the drying assembly includes at least one fan 2801 and at least one first air duct 2803, wherein the first air duct has at least one first air outlet. Since the aforementioned charging component includes a positive charging component and a negative charging component, the positive charging component is more prone to electrochemical corrosion than the negative charging component. Therefore, at least one first air outlet faces the positive charging component, and the fan blows air onto the positive charging component through the first air outlet to dry the positive charging component and ensure that the positive charging component is in a dry state.

[0201] Furthermore, in some embodiments, there are at least two first air outlets, one of which faces the positive charging component and the other faces the negative charging component, in order to dry the positive and negative charging components. For example, the two first air outlets are located between the positive and negative charging components.

[0202] In some embodiments, at least a portion of the drying assembly is disposed within the base station body. For example, at least a portion of the drying assembly is disposed within a sixth receiving cavity. For example, as... Figures 18 to 43 As shown, the fan is disposed within the sixth receiving cavity, and at least a portion of the first air duct is disposed within the sixth receiving cavity. Further, the fan is disposed on one side of the fourth opening, and the first air duct is disposed on one side of the fourth opening. In other embodiments, at least a portion of the drying assembly is further away from the first nozzle than the fourth opening.

[0203] In some embodiments, such as Figures 19 to 43 As shown, at least a portion of the drying components are disposed on the mounting plate. For example, a fan is disposed on the mounting plate, and at least a portion of the first air duct is disposed on the mounting plate. Further, in one embodiment, the fan and at least a portion of the first air duct are disposed on the mounting plate and disposed on one side of the fourth opening; further, the fan and at least a portion of the first air duct are located further away from the first nozzle than the fourth opening.

[0204] Furthermore, in some embodiments, the drying component and the charging component are located on the same side of the fourth opening, so as to guide the air blown out by the drying component to the charging component as quickly as possible to accelerate the drying speed of the charging component.

[0205] In some embodiments, the drying component and the closing mechanism are located on different sides of the fourth opening; or, in other embodiments, such as Figure 23 , Figure 27 , Figure 32 , Figure 36 , Figure 41 As shown, the drying assembly and the closing mechanism are located on the same side of the fourth opening; for example, the drying assembly and the closing mechanism are located on the same side of the fourth opening; furthermore, in some embodiments, such as Figure 23 , Figure 27 , Figure 32 The drying assembly and the shut-off mechanism are located on the same side of the fourth opening, with the shut-off mechanism closer to the fourth opening than the drying assembly. Alternatively, in some embodiments, at least part of the shut-off mechanism is closer to the first nozzle than at least part of the drying assembly.

[0206] In some embodiments, such as Figure 20 , Figure 24 , Figure 29 , Figure 33 As shown, the mounting plate is provided with a sixth mounting section 200016, and at least a portion of the drying components are disposed in the sixth mounting section, for example, a fan and at least a portion of the first air duct are disposed in the sixth mounting section.

[0207] For the base station body itself, the base station body is the shell of the base station. For example, in some embodiments, such as Figure 44 and Figure 45 As shown, the base station body includes a second upper shell 20001a, multiple second side shells 20001b, and a second bottom shell 20001c. The top of the second side shell is connected to the second upper shell, and the bottom of the second side shell is connected to the second bottom shell. Adjacent second side shells are connected to form a cavity with an opening in one side wall. Further, to form the aforementioned third receiving cavity, the base station body also includes a second dust chamber, which is disposed within the cavity, and the inner cavity of the second dust chamber serves as the third receiving cavity. The second upper shell has a fourth opening that communicates with the third receiving cavity.

[0208] In some embodiments, the mounting plate is detachably connected to the base station body. For example, the mounting plate is detachably connected to the second side shell and / or the second upper shell. In some embodiments, the mounting plate can be connected to the base station body by at least one of the following connection methods: threaded connection, magnetic connection, snap-fit ​​connection, key pin connection, locking connection, plug connection, grooved connection, screw connection, etc.

[0209] For example, in some embodiments, the mounting plate and the second upper shell are fixed by means of screw connection and / or snap-fit ​​connection; specifically, in some embodiments, the top of the second upper shell is fixed to the top of the mounting plate by means of screw connection; and / or, a plurality of snaps are provided at the fourth opening on the second upper shell, and a plurality of grooves adapted to the snaps are provided at the fourth opening on the mounting plate, so as to achieve tight fixation between the second upper shell and the mounting plate by snap-fit ​​connection.

[0210] Furthermore, in some embodiments, the side of the second upper shell is fixed to the side of the mounting plate by means of screw connection and / or snap-fit ​​connection. For example, multiple snaps are provided on the outer wall of the mounting plate, and multiple grooves adapted to the snaps are provided on the base station body to improve the installation and fixing effect of the mounting plate; furthermore, screw holes are provided on the snaps, and the fixing effect is further strengthened by screw connection.

[0211] In some embodiments, the mounting plate and the second side shell are fixed by means of snap-fit ​​connection and / or groove connection; for example, in one embodiment, the second side shell is provided with snap-fit ​​and / or groove, and the side of the mounting plate is provided with groove and / or snap-fit, and the two are fixed by the cooperation of snap-fit ​​and groove, that is, the snap-fit ​​is inserted into the groove; and / or, the second side shell is provided with slot and / or protrusion, and the side of the mounting plate is provided with protrusion and / or slot, and the two are fixed by the cooperation of slot and protrusion, that is, the protrusion is inserted into the slot.

[0212] In some embodiments, the first motor and the second motor are the same motor, and the second mounting part and the third mounting part are the same mounting slot, such as... Figure 20 , Figure 24 , Figure 29 , Figure 33 , Figure 37 , Figure 42 As shown, the mounting plate has two second mounting portions (or third mounting portions), which are symmetrically arranged on opposite sides of the fourth opening, for example, on both sides along the direction of movement of the pool robot. Further, in some embodiments, the mounting plate also has two fifth mounting portions, which are located on the other side of the fourth opening, for example, on the side of the fourth opening away from the first nozzle. Further, in some embodiments, the mounting plate also has one fourth mounting portion, which is located on the same side of the fourth opening as the fifth mounting portion. For example, the fourth mounting portion and the fifth mounting portion are located on the side of the fourth opening away from the first nozzle; for example, in some embodiments, at least a portion of the fourth mounting portion is located between the two fifth mounting portions; or, in other embodiments, such as... Figures 20 to 43 As shown, the fourth mounting part is closer to the fourth opening and / or the first nozzle than the fifth mounting part.

[0213] Furthermore, in other embodiments, such as Figure 20 , Figure 24 , Figure 29 , Figure 33 As shown, the sixth mounting portion and the fifth mounting portion are located on the same side of the fourth opening. For example, the sixth mounting portion and the fifth mounting portion are located on the side of the fourth opening away from the first nozzle; furthermore, in some embodiments, the sixth mounting portion is located on one side of a fifth mounting portion to at least dry the positive electrode charging component, for example, in some embodiments, such as Figure 20 , Figure 24 , Figure 29 As shown, at least part of the sixth mounting part is disposed between the two fifth mounting parts to simultaneously dry the positive charging component and the negative charging component.

[0214] In some embodiments, the second mounting portion, third mounting portion, fourth mounting portion, fifth mounting portion, and sixth mounting portion may be configured as at least one structure selected from mounting grooves, mounting seats, and mounting holes. Further, in some embodiments, multiple vertical plates are spaced apart within the mounting groove to provide structural support and heat dissipation.

[0215] It should be noted that the mounting groove can be formed by a downward indentation from the top of the mounting plate towards the bottom; or by setting multiple partitions on the top of the mounting plate.

[0216] In some embodiments, such as Figure 26 and Figure 27 , Figure 45 As shown, the base station also includes a fourth baffle 200021, which is movably disposed on the base station body to open or close the ninth opening 2056. When the first nozzle cleans the first filter box, the fourth baffle closes the ninth opening to prevent liquid in the third receiving cavity from flowing out of the ninth opening, ensuring that the liquid filtered by the second filter box is discharged outside the base station through the drain outlet. When it is necessary to remove or place the second filter box, the fourth baffle is opened to expose the second filter box to the external environment, making it convenient for the user to remove or place the second filter box from or into the third receiving cavity. In some embodiments, the fourth baffle and the base station body can be connected in various ways, such as a rotational connection, a sliding connection, or a magnetic connection.

[0217] In some embodiments, such as Figure 45 As shown, the fourth baffle is configured as a double-layer structure; or, in other embodiments, the fourth baffle may also be configured as a single-layer structure or a multi-layer structure.

[0218] When the pool robot is positioned on the base station to clean the first filter box, the opening and closing states of each structure are as follows: Since the pool robot is outside the pool at this time, there is no need to clean the pool. Therefore, The pool robot is powered on, but it does not perform cleaning tasks at this time. When the pool robot is powered on, it can communicate with the base station (which is also powered on) to control the opening and closing of various components on the base station. The main water pump of the pool robot is not turned on; The motor of the main roller brush on the pool robot is not turned on; The motor of the walking mechanism of the pool robot is not turned on, so that the pool robot remains stationary on the machine; if the main roller brush and the walking mechanism use the same motor, then the same motor of the main roller brush and the walking mechanism is not turned on. If the pool robot is equipped with a first thruster, the motor of the first thruster will not be turned on; If a side brush is installed on the pool robot, the motor of the side brush will not be turned on; If the pool robot is equipped with a floating and diving mechanism, the motor of the float pump is turned on to discharge the liquid or gas in the float chamber; or, the motor of the float pump is not turned on and the liquid or gas in the float chamber is not discharged; or, the liquid or gas in the float chamber has already been discharged before the machine performs self-cleaning. If the fourth inlet is not the pick-up / discharge port, the first cover at the pick-up / discharge port is closed to prevent liquid from splashing out of the pick-up / discharge port during the self-cleaning process of the first filter box. If the fourth inlet is the second water inlet, the motor of the second baffle is turned on, causing the second baffle to rotate to the open state of the second water inlet; subsequently, the motor of the second baffle can remain on to ensure that the second water inlet is always in the open state, and when the first filter box is cleaned, the motor drives the second baffle to rotate to the closed state of the second water inlet; or, after ensuring that the second baffle rotates to the open state of the second water inlet, the motor of the second baffle can be turned off to save power, and when the first filter box is cleaned, the motor is turned on again to drive the second baffle to rotate to the closed state of the second water inlet; When the pesticide dispensing component is installed on the pool robot, its motor is not turned on. In this case, the pool robot is outside the pool and cannot be used for pesticide dispensing. When the pesticide dispensing component is installed on the base station, its motor is turned on, meaning that it performs pesticide dispensing while self-cleaning the first filter box. Alternatively, the motor may not be turned on, meaning that the motor's operation is independent of whether the first filter box is self-cleaning. When the water quality detection component is mounted on the pool robot, its motor is not turned on. In this case, the pool robot is outside the pool and cannot perform water quality testing. When the water quality detection component is mounted on the base station, its motor is turned on, meaning it performs water quality testing while the first filter box is self-cleaning; alternatively, the motor is not turned on, meaning its operation is independent of whether the first filter box is self-cleaning. When the first nozzle actively rotates or extends into the first filter box, its drive motor activates, causing the nozzle to rotate or extend into the pool robot. This motor can remain continuously running to ensure the nozzle is always extended, and once the first filter box is cleaned, the motor drives the nozzle out of the pool robot. Alternatively, once the nozzle is fully inserted into the pool robot, the motor can be turned off to conserve power. After the first filter box is cleaned, the motor can be turned back on to drive the nozzle out of the pool robot. If the pool robot is equipped with a shielding component, the activation of the first nozzle's drive motor simultaneously rotates the shielding component to close the fourth inlet, preventing liquid from splashing out of the fourth inlet during the self-cleaning process of the first filter box.

[0219] The fourth motor or the first motor of the unlocking mechanism is activated, causing the first bottom cover to open the third opening, and the garbage in the first filter box enters the second filter box; When it is necessary to flatten the garbage accumulated in the second filter box, the second motor of the lever mechanism is turned on, so as to move and disperse the garbage in the second filter box by swinging the lever, so as to avoid the garbage from gathering in one place and improve the utilization rate of the internal volume of the second filter box. Once the first filter box has been cleaned, the fourth motor or the third motor of the closing mechanism is activated to drive the first bottom cover to move and close the third opening. When the pool robot needs to be charged, the charging component is controlled to charge the pool robot. When the charging components need to be dried, if the base station is equipped with a drying component, the fan will be turned on to blow air and dry the charging components.

[0220] In some embodiments, the unlocking mechanism, closing mechanism, toggle mechanism, charging component, drying component, etc., can all be configured as detachable modular structures. For example, the unlocking mechanism can be integrated into a whole to form a modular structure, realizing modular assembly. This allows the unlocking mechanism to be assembled into individual modules first, and then installed on the base station and / or pool robot. 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.

[0221] The detachable and fixed connections mentioned in this application can be made by using at least one of the following methods: threaded connection, magnetic connection, snap-fit ​​connection, key pin connection, locking connection, plug connection, grooved connection, screw connection, etc.

[0222] The above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit it. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this disclosure, and should all be included within the protection scope of this disclosure.
