Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0053] This application provides a water tank cleaning system, including a base station and a water tank cleaning robot. The water tank cleaning robot is equipped with a filtration device. The water tank cleaning robot is detachable from the base station. When the water tank cleaning robot is separated from the base station, the filtration device filters the liquid in the water tank.

[0054] In this embodiment, the pool cleaning robot is equipped with a filter device. After the pool cleaning robot is separated from the base station, the filter device will automatically clean the dirt in the pool during the cleaning operation, thus efficiently cleaning the pool and effectively reducing labor costs.

[0055] As shown in Figures 1-4, the base station 100 is equipped with a waste recycling device 1100. When the pool cleaning robot 200 is connected to the base station 100, the waste in the filter device 220 is recycled into the waste recycling device 1100.

[0056] When the pool cleaning robot 200 is running in the pool, the filter device 220 can continuously collect the garbage in the pool 300. When the filter device 220 is full or nearly full, the pool cleaning robot 200 moves towards the base station 100 and connects to the base station 100. The garbage collection device 1100 can collect the garbage in the filter device 220. When the garbage in the filter device 220 decreases, the pool cleaning robot 200 separates from the base station 100 and continues to run in the pool. The filter device 220 continues to collect the garbage in the pool 300. The pool cleaning robot 200 has a long running time in the pool at one time.

[0057] In this way, by setting up a waste collection device 1100, the pool cleaning system 1 can automatically collect the waste in the filter device 220 of the pool cleaning robot 200, increase the single running time of the pool cleaning robot 200, and eliminate the need for users to manually collect the waste in the filter device 220, thus improving the user experience.

[0058] For example, the filtration device 220 includes a filter screen connected to a vibration device configured to vibrate the filter screen. The vibration device can be an ultrasonic oscillator, a vibration motor, or other device capable of driving an object to vibrate. When liquid from the pool enters the filtration device 220, the filter screen traps debris in the liquid, allowing the liquid to flow back to the pool. During this process, some debris may remain on the filter screen. Therefore, when the pool cleaning robot 200 is connected to the base station 100, the vibration device can cause the filter screen to vibrate, dislodging the debris and maximizing the amount of debris remaining in the filter device 220, which is then recycled to the waste collection device 1100.

[0059] In addition, when the pool cleaning robot 200 is separated from the base station 100, the vibration device can also drive the filter screen to vibrate, so that the garbage on the filter screen is vibrated off. Therefore, the water passage area on the filter screen is restored to the maximum state, improving the water passage efficiency and preventing water accumulation in the filter device 220 from causing garbage to overflow into the pool.

[0060] In some embodiments of this application, as shown in FIG3, the base station 100 may be provided with a suction interface 170. When the pool cleaning robot 200 is connected to the base station 100, the suction interface 170 is connected to the outlet of the filter device 220. The suction interface 170 can be inserted into the filter device 220, or the filter device 220 can be inserted into the suction interface 170 to improve sealing and reduce the risk of garbage leakage.

[0061] As shown in Figures 2 and 3, the aforementioned waste recycling device 1100 includes a collection box 111 and a suction pump 112. When the pool cleaning robot 200 is connected to the base station 100, the collection box 111 is connected to the filter device 220. When the pool cleaning robot 200 is connected to the base station 100, the suction pump 112 operates to suck the waste in the filter device 220 into the collection box 111.

[0062] By setting up a vacuum pump 112, it is easy to pump the garbage in the filter device 220 into the collection box 111. When the pool cleaning robot 200 is connected to the base station 100, the vacuum pump 112 starts to run. When the pool cleaning robot 200 is separated from the base station 100, the vacuum pump 112 stops running. This reduces energy consumption and lowers the cost of use.

[0063] The collection box 111 is detachably connected to the base station 100. That is, the collection box 111 can be pulled out of the base station 100, or it can be pushed into the base station 100. In this way, when the garbage in the collection box 111 reaches a certain level, the collection box 111 can be pulled out of the base station 100 to separate it from the base station 100, making it easier to empty the garbage and clean the collection box 111.

[0064] As shown in Figures 2 and 3, the aforementioned waste recycling device 1100 also includes a suction pipe 113, which is connected to the collection box 111. When the pool cleaning robot 200 is connected to the base station 100, the suction pipe 113 is also connected to the filter device 220. The cross-sectional area of ​​the suction pipe 113 can be smaller than that of the collection box 111. This allows for communication between the collection box 111 and the filter device 220, while also providing more space for the collection box 111 to hold more waste. The smaller cross-sectional area of ​​the suction pipe 113 reduces the space occupied by the waste recycling device 1100, thereby reducing the size of the base station 100.

[0065] Furthermore, there can be multiple suction pipes 113, each equipped with a suction pump 112. These multiple suction pumps 112 can start and stop simultaneously, reducing operational complexity and increasing ease of use; alternatively, the multiple suction pumps 112 can start and stop independently, meaning the start and stop of each pump 112 is not affected by the others. This allows for an increase in the number of pumps 112 that can be activated when there is a large amount of waste, and a decrease in the number of pumps 112 that can be activated when there is less waste, thus reducing energy consumption.

[0066] In addition, the multiple suction pipes 113 can serve as redundancy to prevent blockage of one pipe from affecting the overall operation of the pool cleaning system 1.

[0067] As shown in Figures 2 and 3, the aforementioned waste recycling device 1100 also includes a return water pipe 114. The top end of the return water pipe 114 is connected to the collection tank 111, and the return water pipe 114 is configured to discharge the filtered liquid from the collection tank 111 into the water pool 300. The return water pipe 114 may be equipped with a suction pump 112 to accelerate the discharge of liquid from the waste recycling device 1100.

[0068] By setting up a return water pipe 114, water accumulation in the collection box 111 can be avoided, preventing the garbage in the collection box 111 from being carried out by the accumulated water, reducing the resistance of garbage entering the collection box 111, and reducing the probability of bacteria growing in the garbage in the collection box 111.

[0069] For example, the return water pipe 114 can be connected to the lower area of ​​the collection tank 111 to reduce the amount of liquid residue in the collection tank 111, and the suction pipe 113 can be connected to the upper area of ​​the collection tank 111 to prevent the garbage in the collection tank 111 from flowing back to the suction pipe 113 and reduce the probability of garbage leakage.

[0070] In addition, a return water filter screen can be installed at the inlet of the return water pipe 114 to filter the liquid flowing into the return water pipe 114 and improve the cleanliness of the water tank 300.

[0071] As shown in Figures 1-3, the base station 100 is also equipped with an energy storage device 130, which supplies power to the sewage pump 112. The energy storage device 130 may include a battery or a photovoltaic charging device 131. This eliminates the need for continuous charging via wires during base station 100 operation, making it more convenient and extending its lifespan. Furthermore, the energy storage device 130 can be detached from the base station 100 and moved to other locations for charging, making its charging process more flexible.

[0072] As shown in Figure 1, the energy storage device 130 includes a charging device 131. In this way, the energy storage device 130 can continuously convert solar energy into electrical energy, continuously supply power to the sewage pump 112, and extend the service life of the sewage pump 112.

[0073] In some embodiments of this application, at least a portion of the base station 100 is above the liquid surface 310, and the photovoltaic charging device 131 is disposed on the portion of the base station 100 above the liquid surface 310. The photovoltaic charging device 131 has higher efficiency in contacting sunlight, thus the base station 100 has a stronger endurance and also reduces the risk of short circuit of the photovoltaic charging device 131.

[0074] In some other embodiments of this application, at least a portion of the photovoltaic charging device 131 is located below the liquid surface 310, and the portion of the photovoltaic charging device 131 located below the liquid surface 310 has a waterproof structure. This allows for a reduction in the height of the photovoltaic charging device 131, making its installation on the base station 100 more flexible. Furthermore, the waterproof structure helps prevent short circuits in the photovoltaic charging device 131.

[0075] As shown in Figure 4, the base station 100 is also equipped with a first charging device 140, which is connected to the energy storage device 130. The water tank 300 robot is equipped with a second charging device 225. When the water tank cleaning robot 200 is connected to the base station 100, the first charging device 140 and the second charging device 225 are connected.

[0076] For example, the first charging device 140 can be a plug, the second charging device 225 can be a socket, the first charging device 140 and the second charging device 225 can be plugged and unplugged, or the first charging device 140 and the second charging device 225 can be wirelessly charged, such as electromagnetic charging.

[0077] Through the connection of the first charging device 140 and the second charging device 225, the energy storage device 130 can charge the pool cleaning robot 200. The pool cleaning system 1 can realize the automatic charging of the pool cleaning robot 200. Users do not need to pay attention to the battery level of the pool cleaning robot 200 at all times, which helps to extend the single use time of the pool cleaning robot 200.

[0078] As shown in Figure 3, the pool cleaning system 1 also includes a first sensor 180. The first sensor 180 is located at the base station 100 and connected to the vacuum pump 112. The first sensor 180 is configured to detect whether the pool cleaning robot 200 is connected to the base station 100. The vacuum pump 112 starts and stops according to the signal from the first sensor 180.

[0079] The first sensor 180 can be a pressure sensor, and when the pool cleaning robot 200 is connected to the base station 100, the pool cleaning robot 200 presses the first sensor 180; or the first sensor 180 can be an optical sensor, and when the pool cleaning robot 200 is connected to the base station 100, the pool cleaning robot 200 blocks the first sensor 180.

[0080] For example, when the first sensor 180 detects that the pool cleaning robot 200 is connected to the base station 100, the controller 190 controls the start of the vacuum pump 112; when the first sensor 180 detects that the pool cleaning robot 200 is disconnected from the base station 100, the controller 190 controls the stop of the vacuum pump 112.

[0081] When the pool cleaning robot 200 is separated from the base station 100, the activation of the suction pump 112 not only fails to recycle the waste in the filter device 220 to the waste recycling device 1100, but also sucks liquid from the pool into the waste recycling device 1100, potentially causing waste to overflow. Therefore, this application, by setting the first sensor 180 and the controller 190, ensures that the suction pump 112 sucks up the waste from the filter device 220 when it is activated, which not only improves work efficiency but also prevents waste from overflowing from the waste recycling device 1100.

[0082] In some embodiments of this application, the base station 100 may be equipped with a second sensor (not shown in the figure), which is configured to detect the volume of garbage in the collection bin 111. The second sensor may be connected to an alarm device (e.g., a buzzer or flashlight), the control panel 150 of the base station 100, or a mobile terminal, and is configured to remind the user whether the collection bin 111 is full, facilitating timely cleaning of the collection bin 111 and preventing excessive garbage accumulation.

[0083] In some embodiments of this application, the pool cleaning robot 200 is equipped with a third sensor 227, which is configured to detect the volume of debris inside the filter device 220. For example, the third sensor 227 can check the height of debris inside the filter device 220, the volume of debris inside the filter device 220, or the amount of liquid inside the filter device 220, thereby determining the volume of debris inside the filter device 220.

[0084] By setting a third sensor 227, it is possible to detect whether the amount of garbage in the filter device 220 has reached a preset value. The third sensor 227 will feed back the detection result to an alarm device (such as a buzzer or flashlight), the control panel 150 of the base station 100, or a mobile terminal, etc., to remind the user whether the filter device 220 is full of garbage, so that the user can clean the filter device 220 in time and prevent excessive accumulation of garbage in the filter device 220.

[0085] As shown in Figure 4, the base station 100 is also equipped with a control panel 150 and a first signal device 160. The control panel 150 is connected to the first signal device 160. The pool cleaning robot 200 is also equipped with a second signal device 226. The third sensor 227 is connected to the second signal device 226. The first signal device 160 and the second signal device 226 communicate wirelessly or via wired communication.

[0086] The first signal device 160 and the second signal device 226 can communicate via optical signals or via acoustic signals. This eliminates the need for wiring, allowing the pool cleaning robot 200 to move more flexibly and eliminating the risk of wire wear.

[0087] For example, the control panel 150 can display the current status of the water tank 300 robot, such as the battery level and location of the water tank 300 robot; the control panel 150 can also display the current status of the base station 100, such as the battery level of the base station 100 and the current amount of garbage in the garbage collection device 1100.

[0088] Users can operate the control panel 150. The control panel 150 transmits control signals to the pool cleaning robot 200 through the first signal device 160 and the second signal device 226 to control the separation and connection between the pool cleaning robot 200 and the base station 100, which makes it more convenient for users to operate the pool cleaning robot 200.

[0089] The third sensor 227 feeds back the detection result to the second signal device 226, which in turn feeds back the detection result to the first signal device 160. The control panel 150 can display the garbage storage status in the filter device 220. For example, the control panel 150 can display whether the filter device 220 is full of garbage, or the percentage of the current amount of garbage in the filter device 220 to the total capacity of the filter device 220. The user can actively control whether the pool cleaning robot 200 connects to the base station 100 based on the display results of the control panel 150.

[0090] For example, when the control panel 150 shows that the filter device 220 is full of garbage, the user controls the pool cleaning robot 200 to connect to the base station 100; or when the control panel 150 shows that the current amount of garbage in the filter device 220 is not less than 80% of the total capacity in the filter device 220, the user controls the pool cleaning robot 200 to connect to the base station 100.

[0091] In this way, the control panel 150 can display the current amount of garbage in the filter device 220 in real time. Users can know the current amount of garbage in the filter device 220 in real time, so as to determine whether it is necessary to connect the pool cleaning robot 200 to the base station 100. On the one hand, it is conducive to timely recycling of the garbage in the filter device 220 to the garbage recycling device 1100. On the other hand, users can better plan their time.

[0092] In some embodiments of this application, as shown in Figures 1-4, the pool cleaning system 1 includes a controller 190. The controller 190 controls the connection and separation of the pool cleaning robot 200 and the base station 100 according to the signal of the third sensor 227. The controller 190 is installed on the pool cleaning robot 200 and is connected to the third sensor 227.

[0093] The third sensor 227 feeds back the detection results to the controller 190. When the amount of garbage in the filter device 220 reaches the preset value, the controller 190 controls the pool cleaning robot 200 to connect to the base station 100.

[0094] In some other embodiments of this application, the pool cleaning system 1 includes a controller 190, which controls the connection and disconnection of the pool cleaning robot 200 from the base station 100 based on the signal from the third sensor 227. The controller 190 is installed on the base station 100 and is connected to the first signal device 160. The controller 190 is configured to control the connection and disconnection of the pool cleaning robot 200 from the base station 100.

[0095] The third sensor 227 feeds back the detection result to the second signal device 226, which in turn feeds back the detection result to the first signal device 160. When the amount of garbage in the filter device 220 reaches a preset value, the controller 190 sends a control signal to the second signal device 226 through the first signal device 160 to control the connection between the pool cleaning robot 200 and the base station 100.

[0096] In this way, the pool cleaning system 1 can control the pool cleaning robot 200 to automatically move to the base station 100 according to the volume of garbage in the filter device 220, thereby improving the automation level of the pool cleaning system 1. This is beneficial for timely control of the pool cleaning robot 200 to connect with the base station 100 when the filter device 220 of the pool cleaning robot 200 is full of garbage, so as to recycle the garbage in the filter device 220 into the garbage recycling device 1100.

[0097] Furthermore, the pool cleaning system 1 also includes a connecting device, which includes a first connector and a second connector. The first connector is located on the pool cleaning robot 200, and the second connector is located on the base station 100. The first connector and the second connector are detachably connected. The first connector can be a snap-fit, and the second connector can be a slot, with the first and second connectors engaging in a snap-fit ​​relationship; or the first connector can be an electromagnetic component, and the second connector can be a magnetically attracted device such as iron, with the first and second connectors engaging magnetically; or the first connector can be a hook, and the second connector can be a hook groove, with the first and second connectors engaging in a hook-and-hook relationship.

[0098] This facilitates the separation and integration of the pool cleaning robot 200 and the base station 100.

[0099] In some embodiments of this application, the pool cleaning robot 200 may be equipped with a timing device. After running in the pool for a preset time, the pool cleaning robot 200 can autonomously connect to the base station 100. Generally speaking, when the pool cleaning robot 200 has run in the pool for the preset time, and the filter device 220 is full or nearly full of garbage, the pool cleaning robot 200 automatically connects to the base station 100 to empty the filter device 220, resulting in a higher degree of automation and eliminating the need for user operation.

[0100] As shown in Figures 5 to 10, this application embodiment provides a pool cleaning system 1, which includes a base station 100 and a pool cleaning robot 200. The base station 100 has an interface Ⅰ 102. The pool cleaning robot 200 includes a body 210, a filter device 220, and at least one interface Ⅱ 211. The interface Ⅱ 211 is located in or connected to the body 210. The filter device 220 is located inside or connected to the body 210 and includes a dirt-containing space Ⅰ 228. A water flow path is formed between the interface Ⅱ 211 and the dirt-containing space Ⅰ 228 through a flow channel 229 located inside the body 210, with one end connected to the interface Ⅱ 211 and the other end connected to the dirt-containing space Ⅰ 228. When the pool cleaning robot 200 is connected to the base station 100, at least a portion of the interface Ⅰ 102 is connected to at least one interface Ⅱ 211.

[0101] In the pool cleaning system 1 of this application embodiment, when the pool cleaning robot 200 operates in the pool, its filter device 220 collects waste from the pool. After collecting a significant amount of waste, the filter device 220 returns to and connects to the base station 100. When the pool cleaning robot 200 is connected to the base station 100, at least a portion of the base station 100's interface I 102 connects to at least one interface II 211 of the pool cleaning robot 200, thereby allowing interface I 102 to communicate with the dirt-containing space I 228 of the filter device 220 via a flow channel 229. The base station 100 can then be used to recycle the waste in the dirt-containing space I 228. This eliminates the need for manual cleaning of the filter device 220 by the user, thus reducing the user's workload.

[0102] In some embodiments, as shown in Figures 7 and 10, the pool cleaning robot 200 further includes a cover plate 240, which is disposed between the interface II 211 and the dirt-containing space I. When the cover plate 240 is in a first position, the passage between the dirt-containing space I and the interface II 211 is closed; when the cover plate 240 is in a second position, the dirt-containing space I and the interface II 211 are connected. When the pool cleaning robot 200 is connected to the base station 100, the cover plate 240 can be in the second position.

[0103] After the pool cleaning robot 200 collects a significant amount of trash in the pool, during its journey to the base station 100, the cover 240 can be positioned in a first position. This closes the passage between the dirty storage space I and the interface II 211, preventing trash from overflowing from the dirty storage space I 228. After the pool cleaning robot 200 reaches and connects to the base station 100, the cover 240 can be positioned in a second position, allowing the base station 100's interface I 102 to connect to the dirty storage space I 228 via interface II 211, enabling the base station 100 to recycle the trash in the dirty storage space I 228.

[0104] Furthermore, the cover plate 240 can move from the first position to the second position in at least one of the following ways:

[0105] (1) Motor drive; (2) The interaction between interface I 102 and interface II 211 when the pool cleaning robot 200 is connected to the base station 100; (3) Electromagnetic drive. The electromagnetic drive device can be an electromagnet, and a magnet is provided on the cover plate 240. By controlling the magnetization direction of the electromagnet, the magnet on the cover plate 240 can be attracted or repelled, thereby providing driving force for the movement of the cover plate 240.

[0106] In some embodiments, when the pool cleaning robot 200 is connected to the base station 100, at least a portion of interface I 102 is inserted into interface II 211 and touches the cover plate 240 to hold the cover plate 240 in a second position. That is, the cover plate 240 is moved from a first position to a second position by utilizing the interaction generated by the docking of interface I 102 and interface II 211. This method eliminates the need for other devices to drive the movement of the cover plate 240, saving both cost and space.

[0107] In some embodiments, the cover plate 240 moves from the second position to the first position by at least one of the following methods:

[0108] (1) Elastic effect provided by elastic elements (e.g., springs); (2) Motor drive; (3) Electromagnetic device drive.

[0109] In some embodiments, as shown in Figures 7 and 10, the cover plate 240 includes a main body 241 and at least one protrusion 242. When the pool cleaning robot 200 is connected to the base station 100, the protrusion 242 is disposed on the side of the main body 241 near the interface I 102.

[0110] When the pool cleaning robot 200 is connected to the base station 100, the interface I 102 interacts with the protrusion 242 to move the cover plate 240 from the first position to the second position.

[0111] In other words, during the connection process between the pool cleaning robot 200 and the base station 100, the interface I 102 continuously applies a pushing force to the protrusion 242, causing the protrusion 242 to drive the mainboard body 241 to move. Until the connection between the pool cleaning robot 200 and the base station 100 is completed, the mainboard body 241 moves to the second position, and the interface I 102 remains in contact with the protrusion 242, thus keeping the mainboard body 241 in the second position, thereby maintaining communication between the dirt-containing space I and the interface II 211.

[0112] In one exemplary embodiment, when the cover plate 240 reaches the second position, it forms part of the flow channel 229, thereby keeping the fluid passage between the dirt containment space I and the interface II 211 unobstructed.

[0113] In some embodiments, as shown in Figures 7 and 10, the cover plate 240 includes a main body 241 and at least one protrusion 242. The main body 241 is hinged to the interface II 211. The main body 241 is configured to close or open the fluid passage between the dirt-containing space I and the interface II 211. The protrusion 242 is located on the side of the main body 241 near the interface I 102. When the pool cleaning robot 200 is connected to the base station 100, the interface I 102 actuates the protrusion 242.

[0114] During the connection process between the pool cleaning robot 200 and the base station 100, the interface I 102 continuously applies a pushing force to the protrusion 242, causing the protrusion 242 to drive the mainboard body 241 to rotate. Once the connection between the pool cleaning robot 200 and the base station 100 is complete, the mainboard body 241 rotates to the second position.

[0115] Furthermore, as shown in Figure 10, the main board 241 is an arc-shaped plate. When the pool cleaning robot 200 is connected to the base station 100, the main board 241 is attached to one of the flow channel walls in the flow channel 229.

[0116] In this way, when the pool cleaning robot 200 is connected to the base station 100, the flow channel 229 can maintain a large flow area, which helps to improve the efficiency of the base station 100 in garbage collection.

[0117] In some embodiments, as shown in FIG7, interface II 211 is provided on the body 210, or interface II 211 is provided on the filter device 220. When interface II 211 is provided on the body 210, the inlet of the body 210 forms interface II 211; when interface II 211 is provided on the filter device 220, the opening of the filter device 220 forms interface II 211.

[0118] Furthermore, the filter device 220 is connected to the body 210, with the opening of the filter device 220 opposite to the inlet of the body 210, and a cover plate 240 is located at the opening of the filter device 220. With this configuration, the position of the cover plate 240 can be controlled to connect or close the dirt-containing space I and the interface II 211.

[0119] In some embodiments, as shown in Figures 9 and 10, when the pool cleaning robot 200 is connected to the base station 100, the flow channel 229 extends to the lowest point of the dirt-containing space I.

[0120] Understandably, when base station 100 recycles waste from the soiled storage space I, the wastewater in soiled storage space I needs to flow to the interface I 102. The waste in the filter device 220 will be concentrated at the lowest point of soiled storage space I. In this embodiment, when the pool cleaning robot 200 is connected to base station 100, the flow channel 229 extends to the lowest point of soiled storage space I. With this configuration, during waste recycling, the wastewater in soiled storage space I can flow through the flow channel 229 to the interface I 102, and the waste is flushed into the flow channel 229, thereby allowing the waste to enter base station 100 through the interface I 102.

[0121] Furthermore, as shown in Figure 10, the dirt-containing space I has a ramp 2281, which allows the waste to be deposited by gravity at the flow channel opening. In this way, when the waste is recycled, it is easier for the waste to enter the flow channel 229, and then enter the base station 100 through the flow channel 229 and the interface I 102.

[0122] Furthermore, the end of the flow channel 229 near the lowest point of the dirt-containing space I has a funnel-shaped structure. This allows the waste located at the lowest point of the dirt-containing space I to more easily enter the flow channel 229, and then enter the base station 100 through the flow channel 229 and the interface I 102.

[0123] In some embodiments, as shown in Figures 9 and 10, the flow channel 229 has a first flow channel wall 2210 and a second flow channel wall 2211 disposed opposite to each other along a first direction. The first flow channel wall 2210 includes a third section 22101, the wall surface of the third section 22101 is a concave arc-shaped surface, the third section 22101 and the interface II 211 are disposed opposite to each other along a second direction, the first direction is perpendicular to the normal of the plane where the inlet 228 is located, and the second direction is parallel to the normal of the plane where the interface II 211 is located.

[0124] The flow channel 229 has a first flow channel wall 2210 and a second flow channel wall 2211 arranged opposite to each other along a first direction. The first flow channel wall 2210 includes a third section 22101, the wall surface of which is a concave arc-shaped surface. The third section 22101 and the interface II 211 are arranged opposite to each other along a second direction. With this arrangement, when the pool cleaning robot 200 operates in the pool, external water enters the flow channel 229 through the interface II 211 and is first guided by the third section 22101, changing its flow direction and causing the water flow, originally along the second direction, to deviate towards the first direction. During this change in water flow direction, the debris carried by the water is also blocked by the third section 22101, thus hindering the movement of the debris. This prevents the debris from being washed deep into the dirt-containing space I by the water flow, keeping the debris as close as possible to the flow channel opening. In this way, when recycling waste, it is easier for the waste to enter the flow channel 229, and then enter the base station 100 through the flow channel 229 and the interface I 102.

[0125] In some embodiments, as shown in FIG10, the first flow channel wall 2210 further includes a fourth segment 22102, which is located at the end of the third segment 22101 away from the interface II 211. The fourth segment 22102 is connected to the third segment 22101, and the wall surface of the fourth segment 22102 is an outwardly convex arcuate surface.

[0126] After entering the flow channel 229 through the interface II 211, the external water is guided by the third section 22101 to change its flow direction. It is then guided by the fourth section 22102 of the second flow channel wall 2211 and the first flow channel wall 2210, thus flowing into the dirt-containing space I. The fourth section 22102 is constructed with a convex arc surface, which helps improve the flow characteristics of water passing through the inlet flow channel 229, reduces the probability of vortex formation, and thus improves the working efficiency of the pool cleaning robot 200 when cleaning the pool.

[0127] In some embodiments, as shown in FIG10, the wall surface of the second flow channel wall 2211 is a concave arc-shaped surface. When the pool cleaning robot 200 is connected to the base station 100, the second flow channel wall 2211 is lower than the interface II 211.

[0128] The wall surface of the second flow channel 2211 is a concave arc shape, which can better guide the water flow entering the flow channel 229. In addition, when the pool cleaning robot 200 is connected to the base station 100, the second flow channel wall 2211 is lower than the interface II 211, and the second flow channel wall 2211 can be close to the lowest point of the dirt holding space I. In this way, when garbage is collected, it is easier for garbage to enter the flow channel 229.

[0129] In some embodiments, the pool cleaning system 1 further includes a water flow driving device. Under the action of the water flow driving device, water can flow from the dirt holding space I to the interface I 102. During the above process, the garbage in the dirt holding space I enters the interface I 102 with the water flow and is thus recycled by the base station 100.

[0130] In some embodiments, the water flow reaches the interface I102 and is discharged outside the pool. That is, after the water flow carries the waste into the base station 100, it can be discharged outside the pool, meaning the pool does not recycle water.

[0131] In some embodiments, the water flow drive device includes a pump device mounted on the base station 100. When the pool cleaning robot 200 is connected to the base station 100, the pump device can provide suction to allow water to flow from the dirt-containing space I to the interface I 102.

[0132] Furthermore, as shown in Figures 5, 6, and 8, the pump device includes at least one sewage suction pump 112. That is, the number of sewage suction pumps 112 can be set according to actual usage requirements.

[0133] For example, the pumping device includes two suction pumps 112. On the one hand, this can improve the efficiency of waste recycling; on the other hand, it does not cause a significant increase in cost.

[0134] In some embodiments, as shown in FIG60, a water flow guide 1121 is provided on the sewage pump 112. During the process of water flowing through the sewage pump 112, the water flow guide 1121 can divert the garbage, making it easier for the garbage to pass through the sewage pump 112, thereby preventing garbage from adhering to the impeller of the sewage pump 112 and causing the sewage pump 112 to become blocked.

[0135] In some embodiments, as shown in Figures 5 and 6, the pool cleaning system 1 further includes a suction pipe 113. Under the action of the water flow driving device, water can flow from the dirt holding space I through the interface I 102 into the suction pipe 113. The suction pipe 113 can transport the water flow and the garbage carried by the water flow, so that the water flow and garbage flow to the base station 100.

[0136] Furthermore, the suction pipe 113 is configured to at least partially coincide with the central axis of the base station 100.

[0137] Furthermore, the pump device can be installed on the suction pipe 113. When the pool cleaning robot 200 is connected to the base station 100, the pump device can provide suction force when it is working, so that water can flow from the dirt holding space I to the interface I 102 and into the suction pipe 113.

[0138] In some embodiments, the water flow driving device includes a venturi structure. As shown in FIG11, exemplarily, the pool cleaning system 1 also includes a suction connection pipe 115, which is connected to the suction pipe 112, and a venturi structure is formed at the connection. A pump device is disposed on the connection pipe 115. Under the action of the pump device, sewage in the dirty storage space I is driven by the venturi structure to flow out from the interface I 102 and into the suction pipe 113.

[0139] In this embodiment, the pump is not directly mounted on the suction pipe 113, but rather on the connecting pipe 115 that connects to the suction pipe 113. When the pump is operating, a negative pressure is created at the connection point between the connecting pipe 115 and the suction pipe 112. This negative pressure provides suction force to the suction pipe 113, allowing water to flow from the dirty storage space I through the interface I 102 into the suction pipe 113. This arrangement prevents wastewater from directly passing through the pump, thus avoiding the risk of waste carried by the wastewater accumulating at the pump and causing blockage.

[0140] In some embodiments, the water flow drive includes a pump device disposed within the pool cleaning robot 200. That is, the pump device built into the pool cleaning robot 200 can also be used to provide driving force so that water can flow from the dirt holding space I to the interface I 102.

[0141] Furthermore, the pump device can have a first mode and a second mode. When the water flow drive device is in the first mode, it drives the water flow from the outside of the body 110 to the dirt holding space I. When the water flow drive device is in the second mode, it drives the water flow from the dirt holding space I to the docking interface I 102.

[0142] When the pool cleaning robot 200 is cleaning the pool, the water flow drive device is in the first mode. In this mode, external water can enter the filter device 200 for filtration, and the filtered water can be discharged through the drain outlet of the robot body 210. When the pool cleaning robot 200 is connected to the base station 100, the water flow drive device is in the second mode, allowing water to flow from the dirt-containing space I to the interface I 102, carrying waste into the interface I 102, thereby achieving the purpose of waste recycling.

[0143] In some embodiments, as shown in Figures 6 and 12, the base station 100 further includes a collection box 111, which includes a waste-containing space II. Under the action of a water flow driving device, water flows from the waste-containing space I through the interface I 102 to the waste-containing space II. The collection box 111 is configured to store waste; that is, the waste carried by the water flow can be stored in the collection box 111 to facilitate centralized waste disposal by the user.

[0144] In some embodiments, the suction pipe 113 is disposed between the interface I 102 and the collection tank 111. Under the action of the water flow driving device, water flows from the dirty storage space I through the interface I 102, through the suction pipe 113 and to the collection tank 111.

[0145] In some embodiments, as shown in FIG12, the collection box 111 includes a box body 1111 and a receiving device 1114. Under the action of the water flow driving device, water flows from the docking port I 102 to the box body 1111 of the collection box 111. The receiving device 1114 is disposed inside the box body 1111 and includes the dirt containing space II. The receiving device 1114 can be removed from the box body 1111.

[0146] The trash that enters the collection bin 111 will be concentrated in the dirty containment space II of the containment device 1114. The containment device 1114 can be removed from the bin 1111, which makes it easy to clean the trash in the dirty containment space II.

[0147] Furthermore, the containment device 1114 is a containment box and / or containment bag. The containment device 1114 can be removed from the collection box 111 by pulling it out or by removing it through a door. This makes the containment device 1114 easy to remove.

[0148] In some embodiments, as shown in Figures 6 and 12, the collection tank 111 further includes a filter device 116 and a water return structure 1113. Water in the dirty storage space II is filtered by the filter device 116 and then discharged from the collection tank 111 through the water return structure 1113.

[0149] The filtration device 116 can filter the sewage entering the dirty storage space II, and the filtered water flows back to the pool through the return water structure 1113 of the collection tank 111. This configuration allows the collection tank 111 to separate solid waste from the sewage and collect and store only the solid waste, while the collected water flows back to the pool, thus enabling the reuse of water resources.

[0150] For example, the water return structure 1113 may include a water return hole. The water return hole may be provided in the housing 1111.

[0151] Furthermore, the filtration device 116 may be equipped with a valve. When the housing 1114 is installed in the housing 1111, the valve is opened, and the filtration device 116 mates with the inlet 1112 of the housing 1111 and communicates with the docking interface I 102. When the housing 1114 is separated from the housing 1111, the valve is closed.

[0152] In some embodiments, the filter device 116 is detachably connected to the housing 1114. This facilitates cleaning, maintenance, or replacement of the filter device 116.

[0153] In some embodiments, the pool cleaning system 1 further includes a photovoltaic power generation device configured to power the pool cleaning system 1. The photovoltaic power generation device can convert solar energy into electrical energy for use by the pool cleaning system 1, thereby making the pool cleaning system 1 more energy-efficient and environmentally friendly.

[0154] In some embodiments, the pool cleaning system 1 further includes a chemical storage device, wherein the chemical in the chemical storage device comes into contact with at least a portion of the water flow in the pool cleaning system 1. The chemical can sterilize the water flow, thereby making the water in the pool cleaner after treatment.

[0155] In some embodiments, the installation angle of the collection box 111 is adjustable. This design allows the collection box 111 to adapt well to different installation environments and to be installed stably in various environments.

[0156] In some embodiments, as shown in Figures 5 and 19, the body 210 has a body inlet and a body outlet 212. The pool cleaning robot 200 also includes a pump assembly, under the action of which water flows through the body inlet and the filter device 220 and is discharged from the body outlet 212. The pool cleaning system 1 also includes a rinsing device 250, which is located between the pump assembly and the filter device, and the rinsing device 250 is provided with a plurality of drain holes 2521 facing the filter device 220.

[0157] The pump assembly can have a first mode and a second mode. The pump assembly provides suction force, and the suction force provided in the second mode is in the opposite direction to the suction force provided in the first mode. In the first mode, water flows through the inlet of the unit and the filter device 220, and is discharged from the outlet 212. In the second mode, the water flows in the opposite direction and is discharged through the drain hole 2521 of the flushing device 250, thereby flushing the filter device 220. This flushing action promotes the movement of debris in the dirt-containing space I towards the interface I 102. This arrangement facilitates more thorough cleaning of debris in the filter device 220.

[0158] It is understandable that when interface I 102 is located on fuselage 210, interface I 102 can be used as fuselage inlet at the same time, that is, interface I 102 and fuselage inlet are of the same structure.

[0159] In some embodiments, the drain hole 2521 is tapered. This increases the flow rate of the water jet from the drain hole 2521, thereby improving the rinsing effect on the filter device 220.

[0160] Furthermore, the pump assembly may include a motor and an impeller, with the impeller connected to the motor's output shaft, enabling the motor to rotate the impeller. The pump assembly's mode can be switched by adjusting the motor's rotation direction. For example, when the motor rotates forward, the pump assembly is in the first mode; when the motor rotates in reverse, the pump assembly is in the second mode.

[0161] In some embodiments, when the pool cleaning robot 200 is connected to the base station 100, the connection between interface I 102 and interface II 211 is a sealed connection. This ensures the airtightness of the connection and prevents water leakage.

[0162] In some embodiments, as shown in FIG6, the pool cleaning system 1 further includes a seal 109, which surrounds the interface I 102 and is fixed to the base station 100. When the pool cleaning robot 200 is connected to the base station 100, the seal 109 is compressed between the base station 100 and the body 210. This achieves a sealed connection between the interface I 102 and the interface II 211.

[0163] Figure 15 is a structural schematic diagram of a pool cleaning robot provided in an embodiment of this application; Figure 16 is an exploded view of a pool cleaning robot provided in an embodiment of this application; and Figure 17 is a structural schematic diagram of a rinsing device provided in an embodiment of this application. As shown in Figures 15, 16, and 17, the pool cleaning robot 200 provided in this embodiment includes a body 210, a filter device 220, a pump assembly 230, and a rinsing device 250. The body 210 has an internal mounting cavity 213, and the body 210 has an inlet 214 and an outlet 215 communicating with the mounting cavity 213. The filter device 220 is disposed in the mounting cavity 213 and has a filter screen (not shown in the figure). Pump assembly 230 is disposed in mounting cavity 213. Pump assembly 230 has a first mode and a second mode. When pump assembly 230 is in the first mode, it drives water in mounting cavity 213 to flow from inlet 214 to outlet 215. When pump assembly 230 is in the second mode, it drives water in mounting cavity 213 to flow from outlet 215 to inlet 214. Flushing device 250 is located between pump assembly 230 and filter device 220. Flushing device 250 is provided with multiple drain holes 2521 facing the filter screen.

[0164] The water tank cleaning robot 200 in this embodiment has an installation cavity 213 inside its body 210. The filter device 220 and the pump assembly 230 are disposed in the installation cavity 213. When the pump assembly 230 is in the first mode, the pump assembly 230 can provide suction force, so that external water enters the installation cavity 213 through the water inlet 214, and is discharged from the water outlet 215 after passing through the filter device 220. In this way, the water tank can be cleaned.

[0165] Based on this, a flushing device 250 is also provided in the mounting cavity 213. The flushing device 250 is located between the pump assembly 230 and the filter device 220. When the pump assembly 230 is in the second mode, the pump assembly 230 can provide suction force. The direction of the suction force is opposite to the direction of the suction force in the first mode. Under the action of the suction force, external water enters the mounting cavity 213 through the outlet 215 and flows to the inlet 214. During the flow of water in the mounting cavity 213, it will be discharged through the drain hole 2521 of the flushing device 250 and form a flushing effect on the filter screen of the filter device 220. The flushing effect can wash away the debris attached to the filter screen, so that the pool cleaning robot 200 can maintain a good dirt suction capacity.

[0166] Since the pool cleaning robot 200 can rinse the filter screen by adjusting the working mode of the pump assembly 230, it eliminates the need to disassemble and clean the filter device 220 compared to manual cleaning of the filter screen, thus achieving higher cleaning efficiency. In addition, it can also reduce the burden on people, thereby improving the user experience.

[0167] As shown in Figure 15, in some embodiments, the pump assembly 230 includes a motor 231 and an impeller 232, with the output shaft of the motor 231 connected to the impeller 232. The rotation direction of the motor 231 when the pump assembly 230 is in the first mode is opposite to the rotation direction of the motor 231 when the pump assembly 230 is in the second mode.

[0168] The output shaft of motor 231 is connected to impeller 232, and motor 231 can drive impeller 232 to rotate. By adjusting the rotation direction of motor 231 and impeller 232, the pump assembly 230 can be switched between a first mode and a second mode. In one possible example, when motor 231 drives impeller 232 to rotate forward, pump assembly 230 is in the first mode; when motor 231 drives impeller 232 to rotate in reverse, pump assembly 230 is in the second mode.

[0169] As shown in Figures 15 and 17, in some embodiments, the rinsing device 250 includes a mounting baffle 251 and a plurality of nozzles 252 disposed on the mounting baffle 251. Each nozzle 252 is provided with a drain hole 2521. The mounting baffle 251 is located between the pump assembly 230 and the filter device 220 and is connected to the body 210.

[0170] The mounting baffle 251 is positioned between the pump assembly 230 and the filter device 220. The mounting baffle 251 serves to block the water flow, meaning that the water supply path on the flushing device 250 is only through the drain hole 2521. This allows the water to have a higher flow velocity after exiting through the drain hole 2521, thereby improving the flushing ability of the filter screen.

[0171] In some embodiments, the drain hole 2521 has a first aperture at the end near the pump assembly 230 and a second aperture at the end near the filter device 220, wherein the first aperture is larger than the second aperture.

[0172] When the pump assembly 230 is in the second mode, under the action of the pump assembly 230, external water enters the mounting cavity 213 through the outlet 215 and is discharged to the filter screen through the drain hole 2521. Since the first aperture of the drain hole 2521 near the pump assembly 230 is larger than the second aperture near the filter device 220, the water flow is accelerated as it passes through the drain hole 2521. This helps to further increase the flow rate of the water when it is discharged through the drain hole 2521, thereby further improving the flushing ability of the filter screen.

[0173] As shown in Figure 17, in some embodiments, multiple nozzles 252 are arranged in an array. This arrangement expands the distribution range of the nozzles 252, thereby increasing the rinsing range of the filter screen and facilitating a more comprehensive cleaning of the filter screen.

[0174] Figure 18 is a structural schematic diagram of a flushing device provided in another embodiment of this application, and Figure 19 is a structural schematic diagram of a flushing device provided in another embodiment of this application from another perspective. As shown in Figures 18 and 19, in some embodiments, the mounting baffle 251 is provided with a water passage hole 2511, and the flushing device 250 also includes a one-way mechanism 253 disposed at the water passage hole 2511. When the pump assembly 230 is in the first mode, the one-way mechanism 253 is open, allowing water to flow through the water passage hole 2511; when the pump assembly 230 is in the second mode, the one-way mechanism 253 is closed to block the water passage hole 2511.

[0175] When the pump assembly 230 is in the first mode, external water enters the mounting cavity 213 through the inlet 214, passes through the filter 220, and is discharged through the outlet 215 to clean the pool. In the first mode, the one-way mechanism 253 is open, exposing the water passage hole 2511 on the mounting baffle 251. This increases the water flow rate, thereby improving the cleaning efficiency of the pool cleaning robot 200. When the pump assembly 230 is in the second mode, external water enters the mounting cavity 213 through the outlet 215 and flows in the reverse direction. At this time, the one-way mechanism 253 is closed, blocking the water passage hole 2511, so that the water can only be discharged through the drain hole 2521. This increases the flow rate of the water when it is discharged through the drain hole 2521, thereby improving the water's ability to rinse the filter screen.

[0176] As shown in Figures 18 and 19, in some embodiments, the one-way mechanism 253 includes a baffle plate 2531, the area of ​​which is larger than the area of ​​the water passage 2511. The baffle plate 2531 is located on the side of the mounting baffle 251 away from the filter device 220. The baffle plate 2531 is a rubber plate or a silicone plate, and one edge of the baffle plate 2531 is connected to the mounting baffle 251.

[0177] The area of ​​the baffle plate 2531 is larger than the area of ​​the water passage hole 2511, so that the baffle plate 2531 can cover the water passage hole 2511. The baffle plate 2531 is set on the side of the mounting baffle 251 away from the filter device 220. In this way, when the pump assembly 230 is in the second mode, the water flow entering the mounting cavity 213 through the outlet 215 flows towards the mounting baffle 251. Under the action of the water flow, the baffle plate 2531 will fit more tightly with the mounting baffle 251 and maintain the coverage of the water passage hole 2511. Thus, the baffle plate 2531 can block the water passage hole 2511, so that the water flow can only be discharged through the drain hole 2521. This can increase the flow rate of the water when it is discharged through the drain hole 2521, thereby improving the flushing ability of the water flow on the filter screen. In addition, since the water baffle 2531 is made of rubber or silicone, it is a soft material, which allows for a better sealing effect when the water baffle 2531 is in contact with the mounting baffle 251.

[0178] When the pump assembly 230 is in the first mode, the water flowing into the mounting cavity 213 through the inlet 214 flows to the mounting baffle 251 after passing through the filter device 220. Under the impact of the water flow, the baffle 2531 separates from the mounting baffle 251 and deforms, exposing the water passage hole 2511, thereby allowing the water flow to pass through the water passage hole 2511, which can increase the water flow rate and improve the cleaning efficiency of the pool cleaning robot 200.

[0179] As shown in Figures 18 and 19, in some embodiments, there are multiple water passage holes 2511, and each water passage hole 2511 is provided with a one-way mechanism 253. With multiple water passage holes 2511, when the pump assembly 230 is in the first mode, water can flow through multiple water passage holes 2511 simultaneously, thus further increasing the water flow rate and thereby further improving the cleaning efficiency of the pool cleaning robot 200. In addition, each water passage hole 2511 is provided with a one-way mechanism 253, so that when the pump assembly 230 is in the second mode, all water passage holes 2511 can be blocked by the closed one-way mechanism 253, allowing water to be discharged only through the drain hole 2521.

[0180] In some embodiments, the rinsing device 250 is detachably connected to the body 210. This facilitates the removal of the rinsing device 250 for inspection and maintenance.

[0181] As shown in Figures 15, 16, and 17, in some embodiments, the rinsing device 250 includes a mounting baffle 251 and a plurality of nozzles 252 disposed on the mounting baffle 251, each nozzle 252 having a drain hole 2521. The mounting baffle 251 includes a main body 2512 and a mounting portion 2513 disposed on the edge of the main body 2512. The side wall of the body 210 is provided with a limiting protrusion 216, which defines a mounting groove extending along the height direction of the pool cleaning robot 200. The mounting portion 2513 can be inserted into the mounting groove in an insert manner.

[0182] There can be multiple limiting protrusions 216, and two adjacent limiting protrusions 216 can jointly define the mounting groove.

[0183] The mounting baffle 251 includes a main body 2512 and mounting portions 2513 disposed on the edge of the main body 2512. A nozzle 252 is disposed on the main body 2512. There can be two mounting portions 2513, each disposed on one of two opposite edges of the main body 2512. The mounting groove extends along the height of the pool cleaning robot 200. The mounting portions 2513 can be inserted into the mounting groove in an insert-type manner. This makes the rinsing device 250 detachable from the body 210. Furthermore, the installation of the rinsing device 250 is simple and easy to operate, thereby improving the efficiency of rinsing device 250 assembly and disassembly.

[0184] As shown in Figures 20 and 21, the fixing device 500 in this embodiment of the application can install the base station 100 in a water pool. The fixing device 500 includes a connecting member 510. One end of the connecting member 510 is connected to the pool bank 300 of the water pool, and the other end of the connecting member 510 is configured to be connected to the base station 100, so as to install the base station 100 at the side wall 400 of the water pool.

[0185] The pool bank 300 is a flat surface surrounding the pool, primarily designed to facilitate walking along its edge. Understandably, the pool bank 300 is located outside the pool and is necessarily higher than the waterline.

[0186] The base station 100 can be installed in a pool using the fixing device 500 in this embodiment. In use, one end of the connecting member 510 of the fixing device 500 is connected to the pool bank 300, and the other end is connected to the base station 100, thus installing the base station 100 on the side wall 400 of the pool. This allows the underwater cleaning robot to easily return to the location of the base station 100 and connect to it. In this embodiment, the base station 100 is not directly connected to the pool, but rather connected via the fixing device 500. Furthermore, the end of the connecting member 510 connected to the pool bank 300 is positioned outside the pool and above the waterline, ensuring that the connection strength between the fixing device 500 and the pool bank 300 is not affected by water. Therefore, this installation method improves the installation stability of the base station 100, thereby reducing the risk of the base station 100 falling.

[0187] In some embodiments, the connecting member 510 includes a first connecting portion 511, an extension portion 512, and a second connecting portion 513 connected in sequence. The first connecting portion 511 is configured to connect to the pool bank 300 of the pool, and the second connecting portion 513 is configured to connect to the base station 100, so as to install the base station 100 at the side wall 400 of the pool.

[0188] The connecting member 510 has a first connecting portion 511, an extension portion 512, and a second connecting portion 513. Each part has a different function. The first connecting portion 511 is mainly configured to connect to the pool bank 300, the second connecting portion 513 is mainly configured to connect to the base station 100, and the extension portion 512 is mainly configured to connect the first connecting portion 511 and the second connecting portion 513. The connecting member 510 can be a one-piece structure or a split structure. In the latter case, the first connecting portion 511, the extension portion 512, and the second connecting portion 513 can be separately manufactured and then connected together by screws, rivets, adhesives, or other methods.

[0189] In some embodiments, the first connecting portion 511 has a first abutting surface 5111, and the second connecting portion 513 has a second abutting surface 5131. When the first connecting portion 511 is connected to the pool bank 300, the first abutting surface 5111 abuts against the top surface of the pool bank 300, and the second abutting surface 5131 abuts against the side wall 400 of the pool. This arrangement can increase the connection stability between the first connecting portion 511 and the pool bank 300, and increase the positional stability of the second connecting portion 513 relative to the side wall 400 of the pool.

[0190] In some embodiments, the plane containing the first abutment surface 5111 is perpendicular to the plane containing the second abutment surface 5131. Generally, the top surface of the pool bank 300 and the side wall 400 of the pool are perpendicular to each other. Therefore, in this embodiment, the plane containing the first abutment surface 5111 is perpendicular to the plane containing the second abutment surface 5131. In this way, when the first abutment surface 5111 is in close contact with the top surface of the pool bank 300, the second abutment surface 5131 can also naturally be in close contact with the side wall 400 of the pool. As a result, the first connecting portion 511 and the second connecting portion 513 have better positional stability relative to the pool.

[0191] In other embodiments, the first abutment surface 5111 may not directly abut against the top surface of the pool bank 300, but rather indirectly abut against it. For example, a foot can be provided at the bottom of the first abutment surface 5111, and the foot abuts against the top surface of the pool bank 300. Similarly, the second abutment surface 5131 and the side wall 400 of the pool can also be indirectly abutted against each other, for example, a foot can be provided at the bottom of the second abutment surface 5131, and the foot abuts against the side wall 400 of the pool.

[0192] In some embodiments, at least one bent structure is formed on the extension 512. Some pools have horizontally extending bosses at the edge of the pool bank 300, which protrude from the side wall 400 of the pool, thus forming a structure similar to an "eave". By forming at least one bent structure on the extension 512, the extension 512 is made to have a bent shape as a whole. This allows it to better fit pools with bosses at the edge of the pool bank 300, so that the second abutting surface 5131 of the second connecting portion 513 can abut against the side wall 400 of the pool.

[0193] Furthermore, the bending angle of the bending structure is adjustable. When the bending angle of the bending structure changes, the overall shape of the extension 512 also changes. In this way, the shape of the extension 512 can be adjusted more flexibly to adapt to different pools.

[0194] In some embodiments, as shown in FIG20, the second connecting part 513 is provided with a hook 5132, which is configured to suspend the base station 100. That is, the base station 100 can be connected to the second connecting part 513 by hooking, and when the base station 100 is hooked to the second connecting part 513, a relatively stable connection can be maintained between the base station 100 and the second connecting part 513 under the action of the base station 100's own weight. In this embodiment, using a hooking method to connect the base station 100 and the second connecting part 513 also has the advantages of convenient operation and high installation efficiency.

[0195] Furthermore, the number of hooks 5132 is at least two, and there is a gap between any two adjacent hooks 5132. For example, the number of hooks 5132 can be two, three, four, etc. Having at least two hooks 5132 can improve the connection stability between the base station 100 and the second connection part 513. In addition, the gap between any two adjacent hooks 5132 allows the connection points between the base station 100 and the second connection part 513 to be relatively dispersed, which also helps to improve the connection stability between the base station 100 and the second connection part 513.

[0196] In other embodiments, the second connecting part 513 can also be connected to the base station 100 by screws, rivets, clips, etc., thereby achieving a stable connection between the base station 100 and the second connecting part 513.

[0197] In some embodiments, the first connecting part 511 is fixed to the pool bank 300 by bolts, or by adhesive, or by suction cup. In this embodiment, the first connecting part 511 is directly fixed to the pool bank 300. In practical applications, the connection method can be screw connection, adhesive bonding, or suction cup connection. It is understood that since the first connecting part 511 is outside the pool and above the waterline, even if adhesive bonding is used, a stable connection between the first connecting part 511 and the pool bank 300 can be achieved, that is, the bonding strength will not be affected by water.

[0198] In some embodiments, the connecting member 510 is an engineering plastic part. Engineering plastic parts offer good structural strength and rigidity while also being relatively lightweight. Therefore, using engineering plastic parts for the connecting member 510 helps reduce the overall weight of the fixing device 500, thus facilitating its handling. In other embodiments, the connecting member 510 can also be a metal part, such as stainless steel or aluminum alloy, which provides good structural strength and rigidity.

[0199] In some other embodiments, as shown in FIG21, the fixing device 500 further includes a counterweight component 520, with the first connecting portion 511 connected to the counterweight component 520, which is configured to be fixed to the pool edge 300. In this embodiment, the first connecting portion 511 is fixed to the pool edge 300 via the counterweight component 520, meaning the first connecting portion 511 and the pool edge 300 are indirectly connected. It is understood that the counterweight component 520 has a relatively large weight. When the counterweight component 520 is fixedly connected to the pool edge 300, it can have better positional stability. Even if the connection strength between the counterweight component 520 and the pool edge 300 is insufficient, the counterweight component 520 can still improve its positional stability through its own weight, ensuring that it will not shift.

[0200] In practical applications, the configuration component 520 and the pool bank 300 can be connected by bolts, which can give the counterweight component 520 and the pool bank 300 a high connection strength.

[0201] In some embodiments, as shown in FIG21, the configuration component 520 includes a counterweight plate 521. The counterweight plate 521 can be a metal plate. Metal has a high density, and by using a metal plate, a greater weight can be obtained for the same volume. Of course, the counterweight plate 521 can also be a structure with a large weight, such as a cement board or a stone slab.

[0202] In another embodiment, as shown in Figures 22, 23 and 24, the configuration component 520 includes a counterweight plate 521 and a housing 522, with the counterweight plate 521 mounted on the housing 522.

[0203] The outer shell 522 can protect the counterweight plate 521, for example, to prevent external objects from colliding with the counterweight plate 521. Also, when the counterweight plate 521 is a metal plate, the outer shell 522 can waterproof the metal plate to prevent it from rusting when it comes into contact with water.

[0204] In practical applications, the outer shell 522 can be an engineering plastic component with good structural strength and rigidity, thus providing better protection.

[0205] In some embodiments, as shown in Figures 22 and 25, the fixing device 500 further includes a solar panel 530, which is fixed to the top of the counterweight plate 521. The light-receiving surface of the solar panel 530 is exposed in the housing 522, and the solar panel 530 is configured to supply power to the base station 100. The solar panel 530, also known as a solar cell panel or photovoltaic panel, is a device capable of converting light energy into electrical energy through the photoelectric effect or photochemical effect. In this embodiment, the fixing device 500 further includes the solar panel 530 fixed to the counterweight plate 521, and the light-receiving surface of the solar panel 530 is exposed in the housing 522. This allows for convenient use of the solar panel 530 to supply power to the base station 100.

[0206] In practical applications, the solar panel 530 is equipped with a power connection port, and the cable of the base station 100 can be connected to the power connection port, thereby enabling the base station 100 to be electrically connected to the solar panel 530, so that the solar panel 530 can supply power to the base station 100.

[0207] In some other embodiments, the base station 100 can also be directly connected to an AC power source via a cable, thereby using the AC power source to power the base station 100.

[0208] In some embodiments, as shown in Figures 25 and 26, the outer casing 522 includes a bottom casing 5221 and an upper casing 5222 connected to the bottom casing 5221. The solar panel 530 abuts against the upper casing 5221, and an elastic element 550 is provided between the counterweight plate 521 and the bottom casing 5222. During assembly, the solar panel 530 can be connected to the counterweight plate 521 first, and then the upper casing 5222 and the bottom casing 5221 are used to fasten the solar panel 530 and the counterweight plate 521 between the upper casing 5222 and the bottom casing 5221. Because there may be installation errors when connecting the solar panel 530 and the counterweight plate 521, an elastic element 550 is provided between the counterweight plate 521 and the bottom shell 5222. The elastic element 550 provides support for the counterweight plate 521, and the solar panel 530 abuts against the top shell 5222. In this way, the solar panel 530 and the counterweight plate 521 can be fixed between the top shell 5222 and the bottom shell 5221. Furthermore, the elastic element 521 will undergo adaptive deformation to absorb the installation errors between the solar panel 530 and the counterweight plate 521.

[0209] In practical applications, the elastic element 550 is, for example, a rubber block, a silicone block, a spring, etc.

[0210] In some embodiments, as shown in FIG27, FIG28 and FIG29, the second connecting portion 513 has a second abutting surface 5131, and the first connecting portion 511 is connected to the counterweight plate 521 via a connecting shaft assembly 540. The connecting shaft assembly 540 is configured to adjust the included angle between the second abutting surface 5131 and the counterweight plate 521.

[0211] Therefore, when the first connecting part 511 is fixed to the pool bank 300 by the counterweight assembly 520, the angle between the second abutment surface 5131 and the vertical direction can be adjusted more flexibly by the connecting shaft assembly 540. For example, the second abutment surface 5131 can be adjusted to be parallel to the side wall 400 of the pool, or the second abutment surface 5131 can be adjusted to be inclined relative to the side wall 400.

[0212] Furthermore, the connecting shaft assembly 540 includes a rotating shaft 541, a bearing seat 542, and an adjusting member 543. One of the first connecting portion 511 and the counterweight plate 521 is fixedly connected to the rotating shaft 541, and the other of the first connecting portion 511 and the counterweight plate 521 is fixedly connected to the bearing seat 542. The bearing seat 542 includes a base 5421 and an elastic arm 5422 connected to the base 5421. The elastic arm 5422 and the base 5421 together define a receiving groove, and the rotating shaft 541 is fitted into the receiving groove. The adjusting member 543 abuts against the elastic arm 5422, and the adjusting member 543 is configured to adjust the pressure between the elastic arm 5422 and the rotating shaft 541.

[0213] When it is necessary to adjust the angle between the second abutment surface 5131 and the vertical direction, the adjusting member 543 can be used to release the clamping force on the elastic arm 5422, so that the elastic arm 5422 is no longer clamped to the rotating shaft 541. In this way, the rotating shaft 541 can rotate relative to the seat 5421, thereby changing the angle between the second abutment surface 5131 and the vertical direction. After the adjustment is completed, the adjusting member 543 can be used to clamp the elastic arm 5422 again, so that the elastic arm 5422 clamps the rotating shaft 541. In this way, the rotating shaft 541 can be kept fixed relative to the seat 5421, thereby keeping the angle between the second abutment surface 5131 and the vertical direction unchanged.

[0214] In one possible embodiment, the adjusting member 543 includes an adjusting wrench 5431 and a connecting post 5432. The connecting post 5432 is fixed to the base 5421, and the adjusting wrench 5431 is mounted on the connecting post 5432. The adjusting wrench 5431 includes a clamping part 54311, a handle 54312, and a mounting part 54313. The mounting part 54313 is connected to the mounting post 5432, the clamping part 54311 is rotatably connected to the mounting part 54313, and the handle 54312 is fixedly connected to the clamping part 54311. Thus, the handle 54312 can drive the clamping part 54311 to rotate, and during the rotation of the clamping part 54311, the clamping force between the clamping part 54311 and the elastic arm 5422 changes.

[0215] In some embodiments, the first connecting portion 511 and the counterweight plate 521 are also connected by a hinge shaft 560, the central axis of which coincides with the central axis of the rotating shaft 541. This arrangement improves the connection stability between the first connecting portion 511 and the counterweight plate 521, and during the adjustment of the angle between the second abutment surface 5131 and the vertical direction, it facilitates a smoother rotation of the first connecting portion 511 relative to the counterweight plate 521, preventing wobbling during rotation.

[0216] In some embodiments, at least one of the first connecting portion 511, the extension portion 512, and the second connecting portion 513 is provided with a reinforcing rib 514. This can further improve the structural strength and rigidity of the connecting member 510, making the connecting member 510 less prone to deformation and structural damage, thereby increasing the service life of the fixing device 500.

[0217] An embodiment of the second aspect of this application provides a pool cleaning system, which includes a base station 100, a pool cleaning robot (not shown in the figure), and a fixing device 500 as described in any of the above embodiments, wherein a connecting member 510 is connected to the base station 100.

[0218] The pool cleaning system in this embodiment includes a fixing device 500. The base station 100 can be installed in the pool using the fixing device 500. In use, one end of the connecting member 510 of the fixing device 500 is connected to the pool bank 300, and the other end is connected to the base station 100, thus installing the base station 100 on the side wall 400 of the pool. This allows the underwater cleaning robot to easily return to the location of the base station 100 and connect to it. In this embodiment, the base station 100 is not directly connected to the pool, but rather connected via the fixing device 500. Furthermore, the end of the connecting member 510 connected to the pool bank 300 is positioned outside the pool and above the waterline, ensuring that the connection strength between the fixing device 500 and the pool bank 300 is not affected by water. Therefore, this installation method improves the installation stability of the base station 100, thereby reducing the risk of the base station 100 falling.

[0219] As shown in Figures 30, 31, 32, and 40, the pool cleaning system in this embodiment includes a pool cleaning robot 200 and a base station 100. The base station 100 has a first surface 105 that abuts against or approaches the pool bank 300 and a second surface 121 that abuts against or approaches the pool wall 400. The base station 100 has a first portion 110 and a second portion 120. The first surface 105 is disposed on the first portion 110 of the base station 100, and the second surface 121 is disposed on the second portion 120 of the base station 100. The first portion 110 and the second portion 120 are connected by a fixing device 500. The pool cleaning robot 200 can be connected to the second portion 120 of the base station 100.

[0220] The pool bank 300 is a flat surface surrounding the pool, primarily designed to facilitate walking along its edge. Understandably, the pool bank 300 is located outside the pool and is necessarily higher than the waterline.

[0221] In this embodiment, the base station 100 has a first portion 110 and a second portion 120, which are connected by a fixing device 500. The second portion 120 is located on the pool wall 400 of the pool, allowing the pool cleaning robot 200 to connect to it. The first portion 110 can be disposed on the pool bank 300. When a part of the base station 100 is disposed on the pool bank 300, the first surface 105 abuts against or approaches the pool bank 300. This arrangement eliminates the need for the second portion 120 of the base station 100 to be bonded to the pool wall 400, thus improving the adhesion stability caused by water. Furthermore, the first portion 110 of the base station 100 can be connected to the pool bank 300, or the part of the fixing device 500 near the first portion 110 can be connected to the pool bank 300, making the base station 100 more securely installed and improving its installation stability.

[0222] In some embodiments, as shown in Figures 32 and 33, the fixing device 500 is provided with at least one bent structure. Some pools have horizontally extending protrusions at the edge of the pool bank 300, which protrude from the pool wall 400, thus forming a structure similar to an "eave". By forming at least one bent structure on the fixing device 500, the fixing device 500 is generally bent, which can better adapt to pools with protrusions at the edge of the pool bank 300, so that the first plane on the first part 110 of the base station 100 can abut or approach the pool bank 300, and the second plane on the second part 120 can abut or approach the pool wall 400.

[0223] Furthermore, the bending angle of the bent structure is adjustable.

[0224] Understandably, when the bending angle of the bending structure changes, the overall shape of the fixing device 500 will also change. This allows for more flexible adjustment of the shape of the fixing device 500, enabling it to adapt to different pools.

[0225] In some embodiments, the fixing device 500 and the second part 120 are detachably connected, which facilitates the disassembly and assembly of the second part 120 of the base station 100, thereby facilitating maintenance and repair.

[0226] In some embodiments, as shown in FIG33, the fixing device 500 is provided with a hook 5132, which is configured to suspend the second part 120 of the base station 100. That is, the fixing device 500 can be detachably connected to the second part 120 through the hook 5132.

[0227] When the second part 120 is hung on the fixing device 500, the second part 120 and the fixing device 500 can maintain a relatively stable connection under the action of the second part 120's own weight. In addition, the connection between the second part 120 and the fixing device 500 via the hook 5132 also has the advantages of convenient operation and high installation efficiency.

[0228] Furthermore, the number of hooks 5132 can be one or more. When there are multiple hooks 5132, there is a gap between any two adjacent hooks 5132. For example, the number of hooks 5132 can be one, two, three, four, etc. When there are multiple hooks 5132 and there is a gap between any two adjacent hooks 5132, the connection points between the second part 120 and the fixing device 500 can be relatively dispersed, which also helps to improve the connection stability between the second part 120 and the fixing device 500.

[0229] In other embodiments, the fixing device 500 and the second part 120 can also be connected by screws, rivets, clips, etc., thereby realizing a detachable connection between the fixing device 500 and the second part 120.

[0230] In some embodiments, as shown in FIG34, the distance between the fixing device 500 and the pool wall 400 is adjustable, and the distance between the fixing device 500 and the pool bank 300 is adjustable.

[0231] In practical applications, the fixing device 500 includes a first connecting part 511, an extension part 512, and a second connecting part 513 connected in sequence. The first connecting part 511 is connected to the first part 110 of the base station 100, and the second connecting part 513 is configured to be connected to the second part 120 of the base station 100. The distance between the fixing device 500 and the pool wall 400 is adjustable, which can be understood as the distance between the second connecting part 513 and the pool wall 400 being adjustable; the distance between the fixing device 500 and the pool bank 300 is adjustable, which can be understood as the vertical distance between the second connecting part 513 and the pool bank 300 being adjustable.

[0232] With this setup, when the pool cleaning robot 200 is connected to the base station 100, the position of the pool cleaning robot 200 can be flexibly adjusted according to usage needs.

[0233] For example, an adjustment hole 570 and an adjustment bolt 571 are provided between the extension 512 and the second connecting portion 513. The adjustment hole 570 and the adjustment bolt 571 can adjust the distance between the second connecting portion 513 and the pool wall 400. The extension 512 may include a plurality of sub-segments 5121, and an adjustment hole 570 and an adjustment bolt 571 are provided between adjacent sub-segments 5121. This makes the relative position between adjacent sub-segments 5121 adjustable, so that the vertical distance between the second connecting portion 513 and the pool bank 300 can be adjusted.

[0234] In some embodiments, the angle between the fixing device 500 and the pool wall 400 is adjustable. This allows for flexible adjustment of the angle of the pool cleaning robot 200 when connected to the base station 100.

[0235] As shown in Figures 37, 38 and 39, in some embodiments, the fixing device 500 can be connected to the first part 110 via a connecting shaft assembly 540, which is configured to adjust the angle between the fixing device 500 and the pool wall 400.

[0236] Furthermore, the connecting shaft assembly 540 includes a rotating shaft 541, a bearing seat 542, and an adjusting member 543. One of the fixing device 500 and the first part 110 is fixedly connected to the rotating shaft 541, and the other of the fixing device 500 and the first part 110 is fixedly connected to the bearing seat 542. The bearing seat 542 includes a seat body 5421 and an elastic arm 5422 connected to the seat body 5421. The elastic arm 5422 and the seat body 5421 together define a receiving groove, and the rotating shaft 541 is fitted into the receiving groove. The adjusting member 543 abuts against the elastic arm 5422, and the adjusting member 543 is configured to adjust the pressure between the elastic arm 5422 and the rotating shaft 541.

[0237] When it is necessary to adjust the angle between the fixing device and the pool wall 400, the adjusting member 543 can be adjusted to release the clamping force on the elastic arm 5422, so that the elastic arm 5422 is no longer clamped to the rotating shaft 541. In this way, the rotating shaft 541 can rotate relative to the base 5421, thereby changing the angle between the fixing device 500 and the pool wall 400. After the adjustment is completed, the adjusting member 543 can be used to clamp the elastic arm 5422 again, so that the elastic arm 5422 clamps the rotating shaft 541. In this way, the rotating shaft 541 can be kept fixed relative to the base 5421, thereby keeping the angle between the fixing device and the pool wall 400 unchanged.

[0238] In practical applications, the adjusting component 543 includes an adjusting wrench 5431 and a connecting post 5432. The connecting post 5432 is fixed to the base 5421, and the adjusting wrench 5431 is mounted on the connecting post 5432. The adjusting wrench 5431 includes a clamping part 54311, a handle 54312, and a mounting part 54313. The mounting part 54313 is connected to the mounting post 5432, the clamping part 54311 is rotatably connected to the mounting part 54313, and the handle 54312 is fixedly connected to the clamping part 54311. Thus, the handle 54312 can drive the clamping part 54311 to rotate, and during the rotation of the clamping part 54311, the clamping force between the clamping part 54311 and the elastic arm 5422 changes.

[0239] Furthermore, the fixing device 500 is connected to the first part 110 via a hinge shaft 560, the central axis of which coincides with the central axis of the rotating shaft 541. This arrangement improves the connection stability between the fixing device 500 and the first part 110, and during the adjustment of the angle between the fixing device 500 and the pool wall 400, it facilitates a smoother rotation of the fixing device 500 relative to the first part 110, preventing wobbling during rotation. As shown in Figures 42 and 43, in another embodiment, the fixing device 500 is rotatably connected to the first part 110 (e.g., hinged). The fixing device 500 is provided with a limiting member 501, the height of which is adjustable. The limiting member 501 is configured to limit the maximum angle between the fixing device 500 and the first part 110. That is, during the rotation of the fixing device 500 relative to the first part 110, when the angle reaches its maximum value, the top of the limiting member 501 will abut against the first part 110, preventing the fixing device 500 from rotating further. It is understood that if the height of the limiting member 501 is increased, the maximum value of the angle between the fixing device 500 and the first part 110 will decrease; conversely, if the height of the limiting member 501 is decreased, the maximum value of the angle between the fixing device 500 and the first part 110 will increase.

[0240] For example, the limiting member 501 may be a screw connected to a threaded hole in the fixing device 500. By rotating the screw, the height of the screw can be adjusted, thereby limiting the maximum included angle between the fixing device 500 and the first part 110.

[0241] In some embodiments, as shown in FIG33, the fixing device 500 includes a first connecting portion 511, an extension portion 512, and a second connecting portion 513 connected in sequence. The first connecting portion 511 is connected to a first portion 110 of the base station 100, and the second connecting portion 513 is configured to be connected to a second portion 120 of the base station 100. The first connecting portion 511 has a first abutting surface 5111, and the second connecting portion 513 has a second abutting surface 5131. The first abutting surface 5111 abuts against the top surface of the pool bank 300, and the second abutting surface 5131 abuts against the pool wall 400. This configuration can increase the positional stability of the fixing device 500.

[0242] Furthermore, the fixing device 500 can be a one-piece structure or a split structure. In the latter case, each part of the fixing device 500 can be processed and formed separately, and then connected together by means of screw connection, riveting connection, bonding, etc.

[0243] In some embodiments, the plane containing the first abutment surface 5111 is perpendicular to the plane containing the second abutment surface 5131. Generally, the top surface of the pool bank 300 and the pool wall 400 are perpendicular to each other. Therefore, in this embodiment, the plane containing the first abutment surface 5111 is perpendicular to the plane containing the second abutment surface 5131. In this way, when the first abutment surface 5111 is in close contact with the top surface of the pool bank 300, the second abutment surface 5131 can also naturally be in close contact with the pool wall 400. As a result, the first connecting part 511 and the second connecting part 513 have better positional stability relative to the pool.

[0244] In other embodiments, the first abutment surface 5111 may not directly abut against the top surface of the pool bank 300, but rather indirectly abut against it. For example, a foot can be provided at the bottom of the first abutment surface 5111, and the foot abuts against the top surface of the pool bank 300. Similarly, the second abutment surface 5131 and the pool wall 400 can also be indirectly abutted against each other, for example, a foot can be provided at the bottom of the second abutment surface 5131, and the foot abuts against the pool wall 400.

[0245] In some embodiments, at least one of the first connecting portion 511, the extension portion 512, and the second connecting portion 513 is provided with a reinforcing rib 514. This can further improve the structural strength and rigidity of the fixing device 500, making the fixing device 500 less prone to deformation and structural damage, thereby increasing the service life of the fixing device 500.

[0246] In some embodiments, the fixing device 500 is fixed to the pool bank 300 by bolts, or the fixing device 500 is fixed to the pool bank 300 by adhesive applied to the first surface 105, or the fixing device 500 is fixed to the pool bank 300 by suction cups.

[0247] In practical applications, the first connecting part 511 can be fixed to the pool bank 300 by means of bolts, adhesive, or suction cups. It is understood that since the first connecting part 511 is outside the pool and above the waterline, even if adhesive is used, a stable connection between the first connecting part 511 and the pool bank 300 can be achieved, that is, the bonding strength will not be affected by water.

[0248] In some embodiments, the fixing device 500 is an engineering plastic component. Engineering plastic components offer good structural strength and rigidity while maintaining relatively low weight. Therefore, using engineering plastic components in the fixing device 500 helps reduce its overall weight, thus facilitating its handling. In other embodiments, the fixing device 500 may also be a metal component, such as stainless steel or aluminum alloy, which provides good structural strength and rigidity.

[0249] In some embodiments, as shown in Figures 35 and 36, the first part 110 of the base station 100 is provided with a counterweight 102. Since the counterweight 102 has a large weight, the first part 110 can have better positional stability relative to the pool bank 300.

[0250] Furthermore, the counterweight 102 can be a metal plate, cement board, stone slab, etc.

[0251] In some embodiments, as shown in Figures 35 and 36, a solar panel 103 is provided on the counterweight 102, and the solar panel 103 is configured to supply power to the base station 100. The solar panel 103, also known as a solar cell panel or photovoltaic panel, is a device capable of converting light energy into electrical energy through the photoelectric effect or photochemical effect. In this embodiment, the solar panel 103 is provided on the counterweight 102, thus facilitating the use of the solar panel 103 to supply power to the base station 100.

[0252] In practical applications, the solar panel 103 is equipped with a power connection port, and the cable of the base station 100 can be connected to the power connection port, thereby enabling the base station 100 to be electrically connected to the solar panel 103, so that the solar panel 103 can provide power to the base station 100.

[0253] In some other embodiments, the base station 100 can also be directly connected to an AC power source via a cable, thereby using the AC power source to power the base station 100.

[0254] In some embodiments, as shown in Figures 35 and 36, the first part 110 of the base station 100 may include a housing 101, with a counterweight 102 located inside the housing 101. The housing 101 includes a bottom shell 1011 and an upper shell 1012 connected to the bottom shell 1011. A solar panel 103 abuts against the upper shell 10121, and an elastic member 107 is provided between the counterweight 102 and the bottom shell 1011. During assembly, the solar panel 103 can be connected to the counterweight 102 first, and then the upper shell 1012 and the bottom shell 1011 are used to fasten the solar panel 103 and the counterweight 102 between the upper shell 1012 and the bottom shell 1011. Because there may be installation errors when connecting the solar panel 103 and the counterweight 102, an elastic element 107 150 is provided between the counterweight 102 and the bottom shell 1011. The elastic element 150 provides support for the counterweight 102, and the solar panel 103 abuts against the upper shell 1012. In this way, the solar panel 103 and the counterweight 102 can be fixed between the upper shell 1012 and the bottom shell 1011. Furthermore, the elastic element 150 will undergo adaptive deformation to absorb the installation errors between the solar panel 103 and the counterweight 102.

[0255] In practical applications, the elastic element 107 is, for example, a rubber block, a silicone block, a spring, etc.

[0256] In some embodiments, as shown in Figures 40 and 41, the pool cleaning robot 200 includes a filter device 220 and a locking mechanism 260. When the pool cleaning robot 200 is docked with the base station 100, the filter device 220 can be removed from the pool bank 300 by opening the locking mechanism 260. Exemplarily, the locking mechanism 260 is an elastic buckle.

[0257] This makes it easy to remove the filter device 220 from the pool cleaning robot 200 for cleaning, and after cleaning, it is also easy to put the filter device 220 back into the pool cleaning robot 200.

[0258] Furthermore, the locking mechanism 260 is positioned such that it can be opened or locked manually at the pool bank 300.

[0259] In some embodiments, when the pool cleaning robot 200 is docked with the base station 100, the vertical distance between the locking mechanism 260 and the pool bank 300 does not exceed 50cm. This allows a person on the pool bank 300 to reach the locking mechanism 260 of the pool cleaning robot 200 while leaning over, so as to open or close the locking mechanism 260.

[0260] In some embodiments, the pool cleaning system further includes at least one of a water quality testing system and a drug delivery system; when the pool cleaning system is connected to the base station, the water quality testing system is located underwater; the water quality testing system includes at least one of pH detection, temperature detection, and turbidity detection; the drug delivery system is in contact with the water flow in the base station.

[0261] This setup allows the pool cleaning system to test the water quality in the pool and administer chemicals based on the test results, thus enabling the pool cleaning system to perform both water quality monitoring and purification functions.

[0262] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application 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 or all of the technical features therein.
