Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0082] like Figures 1 to 6 As shown, an embodiment of the present application provides a pool cleaning system 10, which includes a base station 100 and a pool cleaning robot 300. The base station 100 is provided with a docking port I 102. The pool cleaning robot 300 includes a body 310, a filter device 320, and at least one docking port II 311. The docking port II 311 is provided on or connected to the body 310. The filter device 320 is provided within or connected to the body 310. The filter device 320 includes a dirt holding space I 321. A water flow path is formed between the docking port II 311 and the dirt holding space I 321 via a flow channel 322. The flow channel 322 is provided within the body 310, with one end connected to the docking port II 311 and the other end connected to the dirt holding space I 321. When the pool cleaning robot 300 is connected to the base station 100, at least a portion of the docking port I 102 docks with the at least one docking port II 311.

[0083] In the pool cleaning system 10 of the present embodiment, when the pool cleaning robot 300 is operating in the pool, the filter device 320 in the pool cleaning robot 300 can collect garbage in the pool. After collecting a large amount of garbage, the filter device 320 returns to the base station 100 and connects with it. When the pool cleaning robot 300 is connected to the base station 100, at least a portion of the docking interface I 102 of the base station 100 docks with at least one docking interface II 311 of the pool cleaning robot 300. This connects the docking interface I 102 to the dirt storage space I 321 of the filter device 320 via the flow channel 322. The base station 100 can then be used to collect garbage in the dirt storage space I 321. This eliminates the need for the user to manually clean the filter device 320 of the pool cleaning robot 300, thereby reducing the user's burden.

[0084] In some embodiments, as Figure 3 、 Figure 6As shown, the pool cleaning robot 300 further includes a cover 330, which is disposed between the docking port II 311 and the dirt holding space I. When the cover 330 is in a first position, the dirt holding space I and the docking port II 311 are closed. When the cover 330 is in a second position, the dirt holding space I and the docking port II 311 are connected. When the pool cleaning robot 300 is connected to the base station 100, the cover 330 can be in the second position.

[0085] After the pool cleaning robot 300 has collected a large amount of garbage in the pool, the cover 330 can be placed in the first position while the pool cleaning robot 300 is moving toward the base station 100. This position closes the passage between the dirt storage space I and the docking port II 311, preventing the garbage from overflowing from the dirt storage space I 321. After the pool cleaning robot 300 reaches the base station 100 and connects with the base station 100, the cover 330 can be placed in the second position to connect the docking port I 102 of the base station 100 with the dirt storage space I 321 via the docking port II 311, thereby enabling the base station 100 to recycle the garbage from the dirt storage space I 321.

[0086] Furthermore, the cover plate 330 can be moved from the first position to the second position by at least one of the following methods:

[0087] (1) Motor drive; (2) When the pool cleaning robot 300 is connected to the base station 100, the interaction between the docking interface I 102 and the docking interface II 311; (3) Electromagnetic device drive. The electromagnetic drive device can be an electromagnet, and a magnet is provided on the cover 330. By controlling the magnetization direction of the electromagnet, the magnet on the cover 330 can be attracted or repelled, thereby providing driving force for the movement of the cover 330.

[0088] In one embodiment, when the pool cleaning robot 300 is connected to the base station 100, at least a portion of the docking port I 102 is inserted into the docking port II 311, actuating the cover plate 330 to maintain the cover plate 330 in the second position. In other words, the interaction between the docking port I 102 and the docking port II 311 causes the cover plate 330 to move from the first position to the second position. This approach eliminates the need for a separate device to drive the movement of the cover plate 330, saving both cost and space.

[0089] In some embodiments, the cover 330 moves from the second position to the first position by at least one of the following methods:

[0090] (1) Elastic action provided by elastic members (such as springs); (2) Motor drive; (3) Electromagnetic device drive.

[0091] In some embodiments, as Figure 3 、 Figure 6 As shown, the cover 330 includes a main body 331 and at least one protrusion 332 . When the pool cleaning robot 300 is connected to the base station 100 , the protrusion 332 is arranged on one side of the main body 331 close to the docking port I 102 .

[0092] When the pool cleaning robot 300 is connected to the base station 100 , the docking interface I 102 interacts with the protrusion 332 to move the cover plate 330 from the first position to the second position.

[0093] That is, during the connection between the pool cleaning robot 300 and the base station 100, the docking interface I 102 continuously applies a thrust to the protrusion 332, causing the protrusion 332 to drive the main board 331 to move. This continues until the pool cleaning robot 300 and the base station 100 are connected. At this point, the main board 331 moves to the second position, and the docking interface I 102 maintains contact with the protrusion 332, thereby maintaining the main board 331 in the second position, thereby maintaining the connection between the dirt holding space I and the docking interface II 311.

[0094] In a specific embodiment, when the cover plate 330 reaches the second position, it forms a part of the flow channel 322 , so that the fluid passage between the dirt receiving space I and the interface II 311 remains unobstructed.

[0095] In some embodiments, as Figure 3 、 Figure 6 As shown, the cover 330 includes a main body 331 and at least one protrusion 332. The main body 331 is hingedly connected to the docking port II 311. The main body 331 is used to close or open the fluid passage between the dirt holding space I and the port II 311. The protrusion 332 is located on the side of the main body 331 near the docking port I 102. When the pool cleaning robot 300 is connected to the base station 100, the docking port I 102 actuates the protrusion 332.

[0096] During the connection between the pool cleaning robot 300 and the base station 100, the docking interface I 102 continuously applies thrust to the protrusion 332, causing the protrusion 332 to rotate the main board 331. When the connection between the pool cleaning robot 300 and the base station 100 is complete, the main board 331 rotates to the second position.

[0097] Further, if Figure 6 As shown, the main board 331 is an arc-shaped plate. When the pool cleaning robot 300 is connected to the base station 100 , the main board 331 is in contact with one of the flow channel walls in the flow channel 322 .

[0098] In this way, when the pool cleaning robot 300 is connected to the base station 100, the flow channel 322 can maintain a larger flow area, which is beneficial to improving the efficiency of the base station 100 when performing garbage collection.

[0099] In some embodiments, as Figure 3 As shown, docking port II 311 is provided on the body 310, or docking port II 311 is provided on the filter device 320. In the case where docking port II 311 is provided on the body 310, the inlet of the body 310 forms docking port II 311; in the case where docking port II 311 is provided on the filter device 320, the opening of the filter device 320 forms docking port II 311.

[0100] Furthermore, the filter device 320 is connected to the body 310, with the opening of the filter device 320 facing the inlet of the body 310, and the cover plate 330 is provided at the opening of the filter device 320. In this arrangement, the position of the cover plate 330 can be controlled to connect the dirt holding space I and the docking port II 311 or to close the passage.

[0101] In some embodiments, as Figure 5 、 Figure 6 As shown, when the pool cleaning robot 300 is connected to the base station 100, the flow channel 322 extends to the lowest point of the dirt receiving space I.

[0102] It is understood that when the base station 100 collects waste from the dirty holding space I, the wastewater in the dirty holding space I must flow toward the docking port I 102. Waste in the filter device 320 will be concentrated at the lowest point of the dirty holding space I. In this embodiment, when the pool cleaning robot 300 is connected to the base station 100, the flow channel 322 extends to the lowest point of the dirty holding space I. This arrangement allows the wastewater in the dirty holding space I to flow through the flow channel 322 toward the docking port I 102 during waste collection, flushing the waste into the flow channel 322, and then entering the base station 100 through the docking port I 102.

[0103] Further, if Figure 6 As shown, the dirt storage space I has a slope 3211, which allows the garbage to be deposited by gravity at the flow channel opening. This helps the garbage to enter the flow channel 322 more easily when it is recycled, and then enter the base station 100 through the flow channel 322 and the docking port I 102.

[0104] Furthermore, the end of the flow channel 322 near the lowest point of the dirt storage space I has a bell-shaped structure. This allows garbage at the lowest point of the dirt storage space I to more easily enter the flow channel 322 and then enter the base station 100 through the flow channel 322 and the docking port I 102.

[0105] In some embodiments, as Figure 5 、 Figure 6 As shown, the flow channel 322 has a first flow channel wall 323 and a second flow channel wall 324 arranged opposite to each other along a first direction, the first flow channel wall 323 includes a first section 3231, the wall surface of the first section 3231 is a concave arc surface, the first section 3231 and the docking port II 311 are arranged opposite to each other along a second direction, the first direction is perpendicular to the normal of the plane where the water inlet 321 is located, and the second direction is parallel to the normal of the plane where the docking port II 311 is located.

[0106] The flow channel 322 has a first flow channel wall 323 and a second flow channel wall 324 arranged opposite each other along a first direction. The first flow channel wall 323 includes a first section 3231 having an inwardly concave arcuate wall surface. Furthermore, the first section 3231 and the docking port II 311 are arranged opposite each other along a second direction. With this arrangement, when the pool cleaning robot 300 is operating in a pool, external water enters the flow channel 322 through the docking port II 311. It is then first guided by the first section 3231, causing the water, originally flowing in the second direction, to shift toward the first direction. During this redirection, waste carried by the water is also blocked by the first section 3231, thereby hindering its movement. This prevents waste from being swept deep into the dirt-receiving space I and keeps it as close to the flow channel opening as possible. In this way, when garbage is recycled, it is helpful for the garbage to enter the flow channel 322 more easily, and then enter the base station 100 through the flow channel 322 and the docking interface I102.

[0107] In one embodiment, Figure 6 As shown, the first flow channel wall 323 further includes a second section 3232 , which is located at an end of the first section 3231 away from the docking port II 311 , is connected to the first section 3231 , and has a wall surface that is an outwardly convex arc surface.

[0108] After entering flow channel 322 through docking port II 311, external water is directed by first section 3231, changing its direction. It is then guided by second flow channel wall 324 and second section 3232 of first flow channel wall 323, ultimately flowing into dirt holding space I. The second section 3232 is constructed as an outwardly convex curved surface, which improves the flow characteristics of water through inlet flow channel 322 and reduces the likelihood of vortex formation, thereby increasing the efficiency of the pool cleaning robot 300 when cleaning a pool.

[0109] In one embodiment, Figure 6As shown, the wall surface of the second flow channel wall 324 is a concave arc surface. When the pool cleaning robot 300 is connected to the base station 100, the second flow channel wall 324 is lower than the docking port II 311.

[0110] The second flow channel wall 324 has a concave curved surface, which can effectively guide the water flow entering the flow channel 322. In addition, when the pool cleaning robot 300 is connected to the base station 100, the second flow channel wall 324 is lower than the docking port II 311 and can be close to the lowest point of the dirt storage space I. This helps facilitate the entry of garbage into the flow channel 322 during garbage collection.

[0111] In some embodiments, the pool cleaning system 10 also 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 docking port I102. In the above process, the garbage in the dirt holding space I enters the docking port I102 with the water flow, and is thus recovered by the base station 100.

[0112] In one embodiment, the water flows out of the pool after reaching the docking port I 102. That is, after the water flows into the base station 100, it can be discharged out of the pool, that is, the pool does not recycle water.

[0113] In one embodiment, the water flow driving device includes a pump device, which is provided on the base station 100. When the pool cleaning robot 300 is connected to the base station 100, the pump device can provide suction force to enable water to flow from the dirt holding space I to the docking port I 102.

[0114] Further, if Figure 1 、 Figure 2 as well as Figure 4 As shown, the pump device includes at least one sewage suction pump 230. That is, the number of sewage suction pumps 230 can be set according to actual usage requirements.

[0115] Exemplarily, the pump device includes two sewage suction pumps 230. On the one hand, the efficiency of garbage collection can be improved, and on the other hand, the cost will not be significantly increased.

[0116] In one embodiment, Figure 10 As shown, the sewage suction pump 230 is provided with a water flow guide 231. When water flows through the sewage suction pump 230, the water flow guide 231 can divert the garbage, making it easier for the garbage to pass through the sewage suction pump 230, thereby preventing the garbage from adhering to the impeller of the sewage suction pump 230 and causing the sewage suction pump 230 to be blocked.

[0117] In one embodiment, Figure 1 、 Figure 2As shown, the pool cleaning system 10 also includes a sewage suction line 220. Under the action of the water flow drive device, water can flow from the dirt holding space I through the docking port I 102 into the sewage suction line 220. The sewage suction line 220 can transport the water flow and the garbage carried by the water flow, so that the water flow and the garbage flow toward the base station 100.

[0118] Furthermore, the sewage suction pipeline 220 is configured to at least partially coincide with the central axis of the base station 100 .

[0119] Furthermore, a pump device can be provided on the sewage suction pipe 220. When the pool cleaning robot 300 is connected to the base station 100, the pump device can provide suction force during operation, so that water can flow from the dirt holding space I to the docking port I 102 and enter the sewage suction pipe 220.

[0120] In some embodiments, the water flow driving device includes a Venturi structure. Figure 7 As shown, the pool cleaning system 10 also includes a suction connection line 240, which is connected to the sewage suction line 230, forming a venturi structure at the connection point. A pump device is provided in the connection line 240. Under the action of the pump device, the sewage in the sewage holding space I is driven by the venturi structure to flow out of the docking port I 102 and into the sewage suction line 220.

[0121] In this embodiment, the pump device is not directly mounted on the sewage suction pipe 220, but rather on a connecting pipe 240 connected to the sewage suction pipe 220. When the pump device is operating, a negative pressure is generated at the connection point between the connecting pipe 240 and the sewage suction pipe 230. This negative pressure provides suction to the sewage suction pipe 220, allowing water to flow from the dirt holding space I through the docking port I 102 and into the sewage suction pipe 220. This arrangement prevents sewage from passing directly through the pump device, thus avoiding the risk of waste carried by the sewage accumulating at the pump device and causing blockage.

[0122] In some embodiments, the water flow driving device includes a pump device, which is disposed within the pool cleaning robot 300. In other words, the pump device built into the pool cleaning robot 300 can also be used to provide driving force to enable water to flow from the dirt holding space I to the docking port I 102.

[0123] Furthermore, the pump device can have a first mode and a second mode. When the water flow driving 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 driving device is in the second mode, it drives the water flow from the dirt holding space I to the docking port I102.

[0124] When the pool cleaning robot 300 is cleaning a pool, the water flow drive device is in the first mode. At this time, external water can enter the filter device 300 for filtration, and the filtered water can be discharged through the drain port of the body 310. When the pool cleaning robot 300 is connected to the base station 100, the water flow drive device is in the second mode, allowing water to flow from the dirt storage space I to the docking port I 102, carrying garbage into the docking port I 102, thereby achieving the purpose of garbage collection.

[0125] In some embodiments, as Figure 2 、 Figure 8 As shown, base station 100 also includes a collection box 210, which includes a waste storage space II. Under the action of a water flow drive, water flows from waste storage space I through docking port I 102 to waste storage space II. Collection box 210 is used to store waste. In other words, waste carried by the water flow can be stored in collection box 210, allowing users to centrally dispose of waste.

[0126] In one embodiment, the sewage suction pipe 220 is disposed between the docking port I 102 and the collection box 210. Under the action of the water flow driving device, water flows from the sewage receiving space I through the docking port I 102 and reaches the collection box 210 through the sewage suction pipe 220.

[0127] In one embodiment, Figure 8 As shown, collection box 210 includes a box body 211 and a receiving device 212. Under the action of a water flow drive, water flows from docking port I 102 to box body 211 of collection box 210. Receiving device 212 is disposed within box body 211 and includes the aforementioned dirt holding space II. Receiving device 212 can be removed from box body 211.

[0128] The garbage entering the collection box 210 will be collected in the dirt holding space II of the receiving device 212. The receiving device 212 can be taken out of the box body 211, so that the garbage in the dirt holding space II can be easily cleaned out.

[0129] Furthermore, the receiving device 212 is a receiving box and / or a receiving bag. The receiving device 212 can be taken out from the collection box 210 by pulling or by setting a valve. Thus, the receiving device 212 is easy to take out.

[0130] In some embodiments, as Figure 2 、 Figure 8 As shown, the collection box 210 further includes a filtering device 250 and a water return structure 2112 . The water in the dirt holding space II is filtered by the filtering device 250 and can be discharged from the collection box 210 through the water return structure 2112 .

[0131] Filtering device 250 filters the sewage entering dirty holding space II. The filtered water then flows back into the pool through return structure 2112 of collection tank 210. This arrangement allows collection tank 210 to separate solid waste from sewage, collecting and storing only the solid waste, while returning the collected water to the pool, thereby reusing water resources.

[0132] Specifically, the water return structure 2112 may include a water return hole. The recovery hole may be provided in the box body 211.

[0133] Furthermore, the filter device 250 may be provided with a valve. When the receiving device 212 is installed in the housing 211, the valve is opened, and the filter device 250 is docked with the inlet 2111 of the housing 211 and communicates with the docking port I 102. When the receiving device 212 is separated from the housing 211, the valve is closed.

[0134] In some embodiments, the filter device 250 is detachably connected to the receiving device 212. This makes it easier to clean, repair, or replace the filter device 250.

[0135] In some embodiments, the pool cleaning system 10 further includes a photovoltaic power generation device, which is used to power the pool cleaning system 10. The photovoltaic power generation device can convert solar energy into electrical energy for use by the pool cleaning system 10, thereby making the pool cleaning system 10 more energy-efficient and environmentally friendly.

[0136] In some embodiments, the pool cleaning system 10 further includes a chemical storage device, wherein the chemical in the chemical storage device contacts at least a portion of the water flow in the pool cleaning system 10. The chemical can be used to sterilize the water flow, thereby making the water in the pool cleaner after treatment.

[0137] In some embodiments, the installation angle of the collection box 210 is adjustable, so that the collection box 210 can better adapt to different installation environments and can be installed more stably in different installation environments.

[0138] In some embodiments, as Figure 1 、 Figure 9 As shown, the body 310 has a body inlet and a body outlet 312. The pool cleaning robot 300 also includes a pump assembly. Under the action of the pump assembly, water flows through the body inlet and the filter device 320 and is discharged from the body outlet 312. The pool cleaning system 10 also includes a flushing device 340. The flushing device 340 is located between the pump assembly and the filter device and is provided with a plurality of drainage holes 341 facing the filter device 320.

[0139] The pump assembly can have a first mode and a second mode. The pump assembly can provide a suction force. The suction force provided by the pump assembly in the second mode is opposite in direction to the suction force provided by the pump assembly in the first mode. When the pump assembly is in the first mode, water flows through the body inlet and the filter device 320 and is discharged from the body outlet 312. When the pump assembly is in the second mode, the water flow moves in the opposite direction and is discharged through the drainage hole 341 of the flushing device 340, thereby forming a flushing effect on the filter device 320. This flushing effect can be used to encourage garbage in the dirt holding space I to move toward the docking port I 102. This arrangement is conducive to more thorough cleaning of garbage in the filter device 320.

[0140] It can be understood that, when the docking port I 102 is provided on the fuselage 310 , the docking port I 102 can be used as the fuselage inlet at the same time, that is, the docking port I 102 and the fuselage inlet have the same structure.

[0141] In one embodiment, the drainage hole 341 is conical in shape, so as to increase the flow rate of the water sprayed from the drainage hole 341 , thereby facilitating an improvement in the flushing effect on the filter device 320 .

[0142] Furthermore, the pump assembly may include a motor and an impeller, wherein the impeller is connected to an output shaft of the motor, and the motor is capable of rotating the impeller. By adjusting the rotation direction of the motor, the pump assembly can be switched between modes. For example, when the motor rotates forward, the pump assembly is in a first mode, and when the motor rotates reversely, the pump assembly is in a second mode.

[0143] In some embodiments, when the pool cleaning robot 300 is connected to the base station 100, the docking between the docking interface I 102 and the docking interface II 311 is sealed. In this way, the sealing of the two can be ensured during connection to prevent water leakage.

[0144] In one embodiment, Figure 2 As shown, the pool cleaning system 10 further includes a seal 400, which is disposed around the docking port I 102 and is secured to the base station 100. When the pool cleaning robot 300 is connected to the base station 100, the seal 400 is compressed between the base station 100 and the body 310, thereby achieving a sealed connection between the docking port I 102 and the docking port II 311.

[0145] The above content is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
