[0082] like Figures 1 to 6 As shown, the 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 interface I 102, and the pool cleaning robot 300 includes a body 310, a filter device 320 and at least one docking interface II 311, wherein the docking interface II 311 is provided on the body 310 or connected to the body 310, the filter device 320 is provided in the body 310 or connected to the body 310, and the filter device 320 includes a dirt holding space I 321, and a water flow path is formed between the docking interface II 311 and the dirt holding space I 321 through a flow channel 322, and the flow channel 322 is provided in the body 310, and one end thereof is connected to the docking interface II 311, and the other end is connected to the dirt holding space I 321. Wherein, when the pool cleaning robot 300 is connected to the base station 100, at least part of the docking interface I 102 is docked with at least one docking interface II 311.

[0083] In the pool cleaning system 10 of the embodiment of the present application, 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 the filter device 320 collects a lot of garbage, it will return to the base station 100 and connect to the base station 100. When the pool cleaning robot 300 is connected to the base station 100, at least part of the docking interface I102 of the base station 100 docks with at least one docking interface II311 of the pool cleaning robot 300, thereby making the docking interface I102 communicate with the dirty holding space I321 of the filter device 320 through the flow channel 322. Then, the base station 100 can be used to recycle the garbage in the dirty holding space I321. In this way, the user does not need to manually clean the filter device 320 of the pool cleaning robot 300, thereby reducing the burden on the user.

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

[0085] When the pool cleaning robot 300 collects a lot of garbage in the pool, the cover plate 330 can be placed in the first position when the pool cleaning robot 300 goes to the base station 100, so that the cover plate 330 closes the passage between the dirty storage space I and the docking interface II 311, which can prevent the garbage in the dirty storage space I 321 from overflowing. After the pool cleaning robot 300 arrives at the base station 100 and connects with the base station 100, the cover plate 330 can be placed in the second position so that the docking interface I 102 of the base station 100 is connected to the dirty storage space I 321 through the docking interface II 311, so that the base station 100 can recycle the garbage in the dirty storage space I 321.

[0086] Further, the cover plate 330 can move 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 may be an electromagnet, and a magnet is provided on the cover plate 330. By controlling the magnetization direction of the electromagnet, the magnet on the cover plate 330 can be attracted or repelled, thereby providing driving force for the movement of the cover plate 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 interface I 102 is inserted into the docking interface II 311 and touches the cover plate 330, so that the cover plate 330 is kept in the second position. In other words, the cover plate 330 is moved from the first position to the second position by utilizing the interaction generated by the docking of the docking interface I 102 and the docking interface II 311. This method does not require the provision of other devices for driving the cover plate 330 to move, which is conducive to saving costs and space.

[0089] In some embodiments, the cover plate 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 parts (such as springs); (2) Motor drive; (3) Electromagnetic device drive.

[0091] In some embodiments, Figure 3 , Figure 6 As shown, the cover plate 330 includes a main board 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 board 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 will continuously apply thrust to the protrusion 332, so that the protrusion 332 drives the main board 331 to move. Until the pool cleaning robot 300 is connected to the base station 100, at which time, the main board 331 moves to the second position, and the docking interface I 102 keeps in contact with the protrusion 332, so that the main board 331 is kept in the second position, and the dirt holding space I and the docking interface II 311 are kept in a connected state.

[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 containing space I and the interface II 311 remains unobstructed.

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

[0096] During the connection between the pool cleaning robot 300 and the base station 100, the interface I 102 will continuously apply thrust to the protrusion 332, so that the protrusion 332 drives the main board 331 to rotate. When the pool cleaning robot 300 and the base station 100 are connected, the main board 331 rotates to the second position.

[0097] Furthermore, if Figure 6 As shown, the main board body 331 is an arc-shaped plate. When the pool cleaning robot 300 is connected to the base station 100 , the main board body 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, Figure 3 As shown, the docking port II 311 is provided on the body 310, or the docking port II 311 is provided on the filter device 320. When the docking port II 311 is provided on the body 310, the inlet of the body 310 forms the docking port II 311; when the docking port II 311 is provided on the filter device 320, the opening of the filter device 320 forms the docking port II 311.

[0100] Furthermore, the filter device 320 is connected to the body 310, the opening of the filter device 320 is opposite to the inlet of the body 310, and the cover plate 330 is arranged at the opening of the filter device 320. In this way, the dirt holding space I and the docking port II 311 can be connected or the passage can be closed by controlling the position of the cover plate 330.

[0101] In some embodiments, 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 containing space I.

[0102] It is understandable that when the base station 100 recycles the garbage in the dirty holding space I, the sewage in the dirty holding space I needs to flow to the docking port I 102. The garbage 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. In this way, when garbage is recycled, the sewage in the dirty holding space I can flow to the docking port I 102 through the flow channel 322, and flush the garbage into the flow channel 322, and then the garbage enters the base station 100 through the docking port I 102.

[0103] Furthermore, if Figure 6 As shown, the dirt storage space I has a slope 3211, so that the garbage is deposited at the flow channel opening by gravity. In this way, when the garbage is recycled, it is convenient 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 port I102.

[0104] Furthermore, one end of the flow channel 322 close to the lowest part of the dirt storage space I has a bell-shaped structure. In this way, the garbage at the lowest part of the dirt storage space I can enter the flow channel 322 more easily, and then enter the base station 100 through the flow channel 322 and the docking port I102.

[0105] In some embodiments, 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 relatively 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 relatively 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 to each other along the first direction, wherein the first flow channel wall 323 includes a first section 3231, the wall surface of the first section 3231 is an inwardly concave arc surface, and the first section 3231 and the docking port II 311 are arranged opposite to each other along the second direction. With such arrangement, when the pool cleaning robot 300 is operating in the pool, after the external water enters the flow channel 322 through the docking port II 311, it is first guided by the first section 3231 to change the flow direction, so that the water flow originally flowing in the second direction is biased toward the first direction. In the process of changing the direction of the water flow, the garbage carried by the water flow is also blocked by the first section 3231, so that the movement of the garbage is blocked, thereby preventing the garbage from being washed into the depth of the dirt holding space I by the water flow, and making the garbage 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 also includes a second section 3232, which is located at one end of the first section 3231 away from the docking port II 311, and is connected to the first section 3231. The wall surface of the second section 3232 is an outwardly convex arc surface.

[0108] After the external water enters the flow channel 322 through the docking port II 311, it is guided by the first section 3231 to change the flow direction, and then guided by the second flow channel wall 324 and the second section 3232 of the first flow channel wall 323, so as to flow into the dirt holding space I. The second section 3232 is configured as an outwardly convex arc surface, which is conducive to improving the flow characteristics of the water flow when passing through the inlet flow channel 322, reducing the probability of vortex formation, and thus helping to improve the working efficiency of the pool cleaning robot 300 when cleaning the 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 wall surface of the second flow channel wall 324 is a concave arc surface, which can better 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 interface II 311, and the second flow channel wall 324 can be close to the lowest point of the dirt storage space I, so that when the garbage is recycled, it is conducive to making the garbage enter the flow channel 322 more easily.

[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 along 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 disposed 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 the water flow to reach the docking port I102 from the dirt receiving space I.

[0114] Furthermore, 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, Fig.10 As shown, the sewage suction pump 230 is provided with a water flow guide 231. When the water flows through the sewage suction pump 230, the water flow guide 231 can divert the garbage so that the garbage can pass through the sewage suction pump 230 more easily, 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 pipeline 220. Under the action of the water flow driving device, the water flow can enter the sewage suction pipeline 220 from the dirt holding space I through the docking port I 102. The sewage suction pipeline 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, the pump device can be arranged on the sewage suction pipeline 220. When the pool cleaning robot 300 is connected to the base station 100, the pump device can provide suction force when working, so that water can flow from the dirt holding space I to the docking port I102 and enter the sewage suction pipeline 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 pipeline 240, which is connected to the sewage suction pipeline 230, and a venturi structure is formed at the connection point. A pump device is provided in the connection pipeline 240. Under the action of the pump device, the sewage in the dirty holding space I is driven by the venturi structure to flow out from the docking port I 102 and enter the sewage suction pipeline 220.

[0121] In this embodiment, the pump device is not directly disposed on the sewage suction pipeline 220, but is disposed on the connecting pipeline 240 connected to the sewage suction pipeline 220. When the pump device is working, a negative pressure is formed at the connection position between the connecting pipeline 240 and the sewage suction pipeline 230, and the negative pressure provides suction force for the sewage suction pipeline 220, so that the water flow can enter the sewage suction pipeline 220 from the dirt holding space I through the docking port I102. In this arrangement, the sewage does not directly pass through the pump device, which can avoid the risk of garbage carried by the sewage accumulating at the pump device and causing the pump device to be blocked.

[0122] In some embodiments, the water flow driving device includes a pump device, which is disposed in 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 so that the water flow can reach the docking port I 102 from the dirt receiving space I.

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

[0124] When the pool cleaning robot 300 performs cleaning work in the pool, the water flow driving device is in the first mode, at which time, external water can enter the filtering 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 driving device is in the second mode, so that the water flow can flow from the dirt holding space I to the docking port I 102 to carry garbage into the docking port I 102, thereby achieving the purpose of garbage recycling.

[0125] In some embodiments, Figure 2 , Figure 8 As shown, the base station 100 further includes a collection box 210, which includes a dirt holding space II. Under the action of the water flow driving device, the water flows from the dirt holding space I through the docking port I 102 to the dirt holding space II. The collection box 210 is used to store garbage, that is, the garbage carried by the water flow can be stored in the collection box 210, so that users can centrally process the garbage.

[0126] In one embodiment, the sewage suction pipeline 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 dirt holding space I through the docking port I 102 and reaches the collection box 210 through the sewage suction pipeline 220.

[0127] In one embodiment, Figure 8 As shown, the collection box 210 includes a box body 211 and a receiving device 212. Under the action of the water flow driving device, the water flows from the docking port Ⅰ102 to the box body 211 of the collection box 210. The receiving device 212 is arranged in the box body 211, and includes the dirt holding space Ⅱ. The receiving device 212 can be taken out from the box body 211.

[0128] The garbage entering the collection box 210 will be collected in the dirt holding space II of the holding device 212. The holding device 212 can be taken out from the box body 211, so that it is convenient to clean up the garbage in the dirt holding space II.

[0129] Further, 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, 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] The filter device 250 can filter the sewage entering the dirty holding space II, and the filtered water flows back to the pool through the return water structure 2112 of the collection box 210. In this way, the collection box 210 can separate the solid waste from the sewage and only collect and store the solid waste therein, and at the same time, the collected water flows back to the pool, so that the water resources can be reused.

[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, a valve may be provided on the filter device 250. When the receiving device 212 is installed in the box 211, the valve is opened, the filter device 250 is docked with the inlet 2111 of the box 211, and is connected with the docking port I102. When the receiving device 212 is separated from the box 211, the valve is closed.

[0134] In some embodiments, the filter device 250 is detachably connected to the receiving device 212. In this way, the filter device 250 can be easily cleaned, repaired or replaced.

[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 drug storage device, wherein the drug in the drug storage device contacts at least a portion of the water flow in the pool cleaning system 10. The drug can be used to sterilize the water flow, so that the water in the pool can be cleaner after treatment.

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

[0138] In some embodiments, Figure 1 , Fig. 9 As shown, the body 310 has a body inlet and a body outlet 312. The pool cleaning robot 300 further includes a pump assembly, under the action of which, water flows through the body inlet and the filter device 320 and is discharged from the body outlet 312. The pool cleaning system 10 further includes a flushing device 340, which 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, and the pump assembly can provide a suction force. The suction force provided by the pump assembly in the second mode is opposite 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 flows 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. By utilizing this flushing effect, the garbage in the dirt holding space I can be urged to move toward the docking port I102. Such a setting is conducive to cleaning the garbage in the filter device 320 more thoroughly.

[0140] It can be understood that, when the docking port I102 is disposed on the fuselage 310, the docking port I102 can be used as a fuselage inlet at the same time, that is, the docking port I102 and the fuselage inlet are the same structure.

[0141] In one embodiment, the drainage hole 341 is in a conical shape, so that the flow rate of the water sprayed from the drainage hole 341 can be increased, thereby facilitating the improvement of the flushing effect on the filter device 320 .

[0142] Further, the pump assembly may include a motor and an impeller, the impeller being connected to an output shaft of the motor, and the motor being capable of rotating the impeller. By adjusting the rotation direction of the motor, the mode switching of the pump assembly may be achieved. 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 of the docking interface I 102 and the docking interface II 311 is sealed. In this way, the sealing of the two can be ensured when connected to prevent water from leaking out.

[0144] In one embodiment, Figure 2 As shown, the pool cleaning system 10 further includes a seal 400, which is disposed around the docking interface I 102 and fixed 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. Thus, a sealed docking between the docking interface I 102 and the docking interface II 311 is achieved.
