Description

Technical Field

[0001] This application relates to the technical field of robots, and particularly to a water-off base station and a pool cleaning system. Background Art

[0002] As a convenient automated device, the pool cleaning robot is widely used in the cleaning and maintenance of pools. After the cleaning task is completed, the pool robot is immersed in water, and the user needs to manually take the pool cleaning robot out of the water. The fishing process is somewhat dangerous, and the long-term immersion causes the service life of the pool cleaning robot to decline. The existing pool cleaning robots need to be manually put into the water by the user and manually taken out of the water after use, which is inconvenient to operate. Therefore, how to enable the pool cleaning robot to complete operations such as returning to the pile more conveniently and automatically has become a technical problem to be solved. Summary of the Invention

[0003] This application provides a water-off base station and a pool cleaning system that enable the pool cleaning robot to complete returning to the pile more conveniently and automatically.

[0004] In a first aspect, an embodiment of this application provides a water-off base station, which includes: A base station main body; A towing mechanism, which is movably connected to the base station main body. The towing mechanism is used to tow the pool cleaning robot ashore or send the pool cleaning robot into the pool. The towing mechanism includes: A towing main body, including a bottom plate and two side plates provided on both sides of the bottom plate. The bottom plate and the two side plates enclose an accommodation cavity for accommodating the pool cleaning robot, and at least one end of the accommodation cavity is provided with an opening; A movable baffle, which is provided at the opening and rotatably connected to the two side plates. When the movable baffle contacts the pool cleaning robot, it can rotate under the action of the pool cleaning robot to open the opening, and the movable baffle can move toward the inside of the accommodation cavity under the action of the pool cleaning robot.

[0005] A water-off base station provided by the present application, the water-off base station includes a base station main body and a towing mechanism; the towing mechanism is movably connected to the base station main body, and the towing mechanism is used to tow the pool cleaning robot onto the shore or send the pool cleaning robot into the pool. The towing mechanism includes a towing main body and a movable baffle. The towing main body includes a bottom plate and two side plates provided on both sides of the bottom plate. The bottom plate and the two side plates enclose a receiving cavity for receiving the pool cleaning robot, and at least one end of the receiving cavity is provided with an opening; the movable baffle is provided at the opening and is rotatably connected to the two side plates. When the movable baffle contacts the pool cleaning robot, it can rotate under the action of the pool cleaning robot to open the opening, and the movable baffle can move toward the inside of the receiving cavity under the action of the pool cleaning robot; After the pool cleaning robot finishes the cleaning task, the pool cleaning robot moves to the position where the towing mechanism is located. The pool cleaning robot contacts the movable baffle and opens the opening to achieve automatic unlocking and enter the receiving cavity of the towing mechanism; generally, when the pool cleaning robot contacts the movable baffle, if the friction force of the pool wall is large, the pool cleaning robot will continuously apply a force to the entire towing mechanism, and this force may cause the towing mechanism to be lifted up, resulting in a failure of docking; if the friction force of the pool wall is insufficient, the pool cleaning robot will slip in place or stay still until the baffle is opened at a certain angle by the crawler wheels. In the present application, it is designed that the movable baffle can move toward the inside of the receiving cavity under the action of the pool cleaning robot while rotating, so that the pool cleaning robot can continue to move forward after contacting the movable baffle, avoiding the pool cleaning robot from lifting the towing mechanism upward or pushing it out of the direction away from the pool wall, keeping the towing mechanism in contact with the pool wall, or avoiding the pool cleaning robot from staying in place for a while and only being able to move forward after the movable baffle is opened downward, promoting the smooth docking of the pool cleaning robot.

[0006] The above process does not require manually putting the pool cleaning robot into the water and taking it out of the water. Moreover, it can timely take out the pool robot when the pool cleaning robot finishes the cleaning task, reducing the risk of the service life of the pool cleaning robot decreasing due to long-term immersion in water, making the use of the pool cleaning robot more convenient.

[0007] In an optional implementation manner, a rotating chute is provided at a position of the side plate close to the opening; the movable baffle includes a baffle main body, a swing arm and a rotating shaft. The rotating shaft is arranged in the rotating chute, and both ends of the swing arm are respectively connected to the baffle main body and the rotating shaft. When the baffle main body contacts the pool cleaning robot, it can push the rotating shaft to slide in the rotating chute.

[0008] In an optional implementation manner, the extending direction of the rotating chute is consistent with the traveling direction of the pool cleaning robot entering the receiving cavity from the opening.

[0009] In an alternative embodiment, the rotating chute has a first end and a second end. The first end is close to the opening, and the second end is far from the opening. When the rotating shaft is located at the first end, the movable baffle closes the opening. When the rotating shaft is located at the second end, the movable baffle opens the opening.

[0010] In an alternative embodiment, the movable baffle further includes an elastic reset member. One end of the elastic reset member is connected to the rotating shaft, and the other end of the elastic reset member is connected to the side plate. The elastic deformation amount of the elastic reset member when the rotating shaft is located at the first end is less than the elastic deformation amount of the elastic reset member when the rotating shaft is located at the second end.

[0011] In an alternative embodiment, the elastic reset member is a tension spring. The first end of the tension spring is fixedly connected to the side plate, and the second end of the tension spring is connected to the rotating shaft.

[0012] In an alternative embodiment, when the rotating shaft is located at the first end, the tension spring is in a first stretched state. When the rotating shaft is located at the second end, the tension spring is in a second stretched state. The stretching length in the second stretched state is greater than the stretching length in the first stretched state.

[0013] In an alternative embodiment, when the rotating shaft is located at the first end, the extending direction of the swing arm is parallel to the extending direction of the side plate. When the rotating shaft is located at the second end, the extending direction of the swing arm is perpendicular to the extending direction of the side plate.

[0014] In an alternative embodiment, a limiting member is provided outside the rotating chute for limiting the positions of the movable baffle when opening and closing the opening.

[0015] In an alternative embodiment, the limiting member surrounds a part of the circumferential side of the rotating chute. A notch is formed on the outside of the rotating chute that is not surrounded by the limiting member. The rotating shaft can rotate within the area defined by the notch.

[0016] In an alternative embodiment, the movable baffle includes a baffle body, a swing arm and a rotating shaft. The rotating shaft is provided on the side plate. The swing arm includes a fixed arm and a telescopic arm that can telescopically move relative to the fixed arm. The telescopic arm is connected to the baffle body, and the fixed arm is connected to the rotating shaft.

[0017] In an alternative embodiment, the towing mechanism has a deployed position and a retracted position. When the towing mechanism is in the retracted position, it is located on the base station main body. When the towing mechanism is in the deployed position, at least a part of it extends below the water surface of the pool.

[0018] In an alternative embodiment, the towing mechanism has a first position and a second position. When the towing mechanism is in the first position, the towing mechanism is located above the base station main body. When the towing mechanism is in the second position, at least part of the towing mechanism is located below the water surface.

[0019] In a second aspect, an embodiment of the present application provides a pool cleaning system, including a pool cleaning robot and a water-off base station as described in the second aspect. The pool cleaning robot is located in the accommodation cavity of the towing mechanism. The water-off base station is used to tow the pool cleaning robot onto the shore or send the pool cleaning robot into the pool.

[0020] In an alternative embodiment, the pool cleaning robot includes a track, a track driving assembly, and a water pump. The track driving assembly is used to drive the track to rotate. During the process of the pool cleaning robot entering the accommodation cavity, the track driving assembly is used to drive the track to rotate in a first rotation direction, and the track drives the movable baffle to move from the first state to the second state; the water pump is in a working state, and the pressure generated by the water pump on the movable baffle is greater than the restoring force of the movable baffle from the second state to the first state.

[0021] In an alternative embodiment, a plurality of first protrusions are provided on the outer surface of the track, and a number of second protrusions are provided on the surface of the movable baffle facing away from the accommodation cavity. When the track contacts the surface of the movable baffle facing away from the accommodation cavity and the track advances into the accommodation cavity, at least part of the first protrusions engages with at least part of the second protrusions, and the movable baffle moves from the first state to the second state under the action of the track.

[0022] In an alternative embodiment, when the pool cleaning robot is located in the accommodation cavity, the tail end of the track is separated from the movable baffle, and the movable baffle rotates to the first state under the restoring force.

Detailed implementation manners

[0028] The technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in the present application are only a part of the embodiments, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments provided in the present application without creative efforts belong to the protection scope of the present application.

[0029] In the present application, the mention of "embodiment" means that the specific features, structures or characteristics described in connection with the embodiment may be included in at least one embodiment of the present application. The phrase appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it an exclusive, independent or alternative embodiment to other embodiments. Those skilled in the art can explicitly and implicitly understand that the embodiments described in the present application can be combined with other embodiments.

[0030] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example: a component or device including one or more parts is not limited to the one or more parts listed, but optionally further includes one or more parts not listed but inherent in the product shown, or one or more parts that should be possessed based on the described function.

[0031] Please refer to Figures 1 - 3 , the present application provides a water-off base station 1000 for a pool cleaning robot 200.

[0032] Please refer to Figures 1 - 3 , the water-off base station 1000 includes a towing mechanism 100.

[0033] Further optionally, please refer to Figures 1 - 3 , the water-off base station 1000 further includes a base station main body 300.

[0034] The base station main body 300 is fixedly arranged on the bank of the pool, and the towing mechanism 100 is movably connected to the base station main body 300. The towing mechanism 100 is used to tow the pool cleaning robot 200 from the pool onto the shore, so that the pool cleaning robot 200 leaves the water surface; or, the towing mechanism 100 is further used to send the pool cleaning robot 200 in the ashore state into the pool to facilitate the pool cleaning robot 200 to enter the water.

[0035] Please refer to Figures 1 - 3 , the towing mechanism 100 has a second position W2 and a first position W1. In other words, the towing mechanism 100 can move relative to the base station main body 300 to the first position W1 or the second position W2.

[0036] Among them, the first position W1 is the position where the towing mechanism 100 is separated from the water surface and is set on the base station main body 300.

[0037] Please refer to Figure 1 , when the towing mechanism 100 is in the first position W1, the towing mechanism 100 is located above the base station main body 300, that is, the towing mechanism 100 is in the ashore state. When the pool cleaning robot 200 is arranged in the accommodation cavity of the towing main body, the pool cleaning robot 200 is also in the ashore state.

[0038] Please refer to Figure 2 , when the towing mechanism 100 is in the second position W2, at least part of the towing mechanism 100 is located below the water surface. For example, the towing mechanism 100 is hung on the pool wall to facilitate the pool cleaning robot 200 in the accommodation cavity to enter the water or, the pool cleaning robot 200 in the pool enters the towing mechanism 100. In other words, the second position W2 is the position where the towing mechanism 100 fits against the pool wall M1 or other positions at least partially located underwater, so that the pool cleaning robot 200 can move from the pool wall M1 to the towing mechanism 100 or enter and exit the water from the towing mechanism 100.

[0039] Optionally, the towing mechanism 100 is a deployable and retractable structure. The towing mechanism 100 has a deployed position and a retracted position. When the towing mechanism 100 is in the retracted position, it is located on the base station main body 300. When the towing mechanism 100 is in the deployed position, at least part of it extends below the water surface of the pool.

[0040] Please refer to Figure 4 , the towing mechanism 100 includes a towing main body 10 and a movable baffle 20.

[0041] The towing main body 10 includes a bottom plate 14 and two side plates arranged on both sides of the bottom plate 14. The two side plates are the first side plate 11 and the second side plate 13 respectively. The first side plate 11 and the second side plate 13 are oppositely arranged in the width direction X. The bottom plate 14 is connected between the first side plate 11 and the second side plate 13.

[0042] Please refer to Figure 4 , the bottom plate 14 and the two side plates enclose an accommodation cavity 10a for accommodating the pool cleaning robot 200.

[0043] Please refer to Figure 4, at least one end of the receiving cavity 10a is provided with an opening 10b. In this embodiment, one end of the receiving cavity 10a in the Y direction is the opening 10b, and the other end is the front plate 12. The front plate 12 and the opening 10b are oppositely arranged in the Y direction. The front plate 12 is connected between the first side plate 11 and the second side plate 13. The first side plate 11, the front plate 12 and the second side plate 13 are respectively connected to three sides of the bottom plate 14. The bottom plate 14, the first side plate 11, the front plate 12 and the second side plate 13 enclose a receiving cavity 10a for housing the pool cleaning robot 200. In other words, the towing body 10 has a receiving cavity 10a and an opening 10b communicating with the receiving cavity 10a. The opening 10b is located between the first side plate 11 and the second side plate 13 and at a position opposite to the front plate 12. The bottom plate 14 forms the bottom wall of the receiving cavity 10a. The first side plate 11, the front plate 12 and the second side plate 13 respectively form three side walls of the receiving cavity 10a. The side of the towing body 10 opposite to the bottom plate 14 can be open. The receiving cavity 10a is used to house the pool cleaning robot 200.

[0044] In other embodiments, both ends of the receiving cavity 10a in the Y direction are openings 10b. When the pool cleaning robot 200 is disposed in the receiving cavity 10a, the bottom of the pool cleaning robot 200 is engaged with the bottom plate 14, so that the pool cleaning robot 200 can be relatively fixed in the receiving cavity 10a and leave the water surface along with the towing mechanism 100.

[0045] The following embodiments will be described by taking the towing body 10 including the front plate 12 as an example.

[0046] Please refer to Figure 4 and Figure 5 , the movable baffle 20 is rotatably connected to the towing body 10. The movable baffle 20 is disposed at the opening 10b of the receiving cavity 10a and is rotatably connected to the two side plates (i.e., the first side plate 11 and the second side plate 13). The movable baffle 20 is used to open or close the opening 10b of the towing body 10.

[0047] The movable baffle 20 is used to be in transmission cooperation with the pool cleaning robot 200 to be in a second state.

[0048] Specifically, when the movable baffle 20 contacts the pool cleaning robot 200, it can be rotated under the action of the pool cleaning robot 200 to open the opening 10b, so that the movable baffle 20 rotates to the second state relative to the towing body 10.

[0049] Further, for example, the movable baffle 20 can be in direct contact with the pool cleaning robot 200. The walking wheels of the pool cleaning robot 200 rotate, thereby driving the movable baffle 20 to rotate to the second state. The second state is the state where the movable baffle 20 opens the opening 10b.

[0050] Please refer to Figure 5 When the movable baffle 20 is in the second state, the movable baffle 20 opens the opening 10b. The movable baffle 20 is disposed outside the opening 10b. For example, the movable baffle 20 is disposed on the side where the bottom plate 14 is located, and the pool cleaning robot 200 can enter or exit the accommodation cavity 10a from the opening 10b or enter the accommodation cavity 10a from the outside through the opening 10b.

[0051] In the general technology, the pool cleaning robot 200 is locked in the towing mechanism 100 or on the base station main body 300 by means of an electric control component or the like. This method requires the setting of more electronic components, has a complex structural design, and has a certain degree of unreliability. At the same time, the unlocking and removal of the pool cleaning robot 200 also become a limitation. If the design often wants to be able to unlock itself, then the locking will not be too firm and the reliability is relatively poor.

[0052] In this application, by designing the transmission cooperation between the pool cleaning robot 200 and the movable baffle 20, that is, the physical interaction and cooperation between the pool cleaning robot 200 and the movable baffle 20, the movable baffle 20 can be driven to be in the second state, so that the pool cleaning robot 200 can open the movable baffle 20 by itself, and then open the opening 10b. There is no need to set an electric drive member and a transmission member, which reduces the setting of parts and components, saves energy consumption, and at the same time, the pool cleaning robot 200 directly contacts the movable baffle 20 to "open the door", improving the reliability of unlocking.

[0053] For example, after the pool cleaning robot 200 finishes the cleaning task at the bottom of the pool, it will move upward along the pool wall M1 to move to contact the movable baffle 20 of the towing mechanism 100. For example, the walking wheels of the pool cleaning robot 200 rotate to drive the movable baffle 20 to rotate to the second state of opening the opening 10b. The pool cleaning robot 200 enters the accommodation cavity 10a of the towing mechanism 100 through the opening 10b of the towing mechanism 100. After the pool cleaning robot 200 completely enters, the movable baffle 20 closes the opening 10b, and the movable baffle 20 is in the first state. Then the towing mechanism 100 moves relative to the base station main body 300 to drive the pool cleaning robot 200 to move in a direction away from the water surface until the towing mechanism 100 is stacked on the base station main body 300, that is, the towing mechanism 100 is in the first position W1, so as to realize the automatic off-shore of the pool cleaning robot 200 in the pool. When the pool cleaning robot 200 needs to perform the cleaning task, first, the towing mechanism 100 moves relative to the base station main body 300 to drive the pool cleaning robot 200 to move in a direction close to the water surface until the towing mechanism 100 fits against the pool wall M1, and the towing mechanism 100 is in the second position W2. Then the movable baffle 20 opens the opening 10b so that the pool cleaning robot 200 falls into the water, thus realizing the automatic entry of the pool cleaning robot 200 into the water.

[0054] Further, when the pool cleaning robot 200 moves upward along the pool wall M1 to contact the movable baffle 20 of the towing mechanism 100, during the process of the pool cleaning robot 200 opening the movable baffle 20, since the pool cleaning robot 200 still keeps moving forward, when the pool cleaning robot 200 contacts the movable baffle 20, it has a forward thrust force on the movable baffle 20. Without the possibility of yielding, the pool cleaning robot 200 will not be able to move forward, that is, it will slip in place until the movable baffle 20 is pressed down to a certain angle before it can continue to move forward. The material of the pool wall M1 affects the machine friction. For example, on a wall with better friction, the pool cleaning robot 200 may not slip in place as described above, which may cause abnormal movement of the towing mechanism 100, such as the towing mechanism 100 being lifted upward or pushed out and deviating from the direction of the pool wall M1, resulting in the pool cleaning robot 200 being unable to enter the towing mechanism 100, that is, the towing mechanism 100 fails to dock.

[0055] Based on the above problems, the movable baffle 20 can rotate and move synchronously towards the inside of the accommodation cavity 10a (the side where the front plate 12 is located). When the pool cleaning robot 200 contacts the movable baffle 20, it has a pushing force on the movable baffle 20 in the forward direction. The movable baffle 20 can move towards the inside of the accommodation cavity 10a (the side where the front plate 12 is located) under the action of the pushing force of the pool cleaning robot 200 in the forward direction, avoiding the towing main body 10 from being lifted upward or pushed out and deviating from the direction of the pool wall M1. In addition, since the pool cleaning robot 200 contacts the movable baffle 20 and also has a rotating force on the movable baffle 20 downward (towards the pool wall M1), the movable baffle 20 rotates towards the pool wall M1 side while moving towards the inside of the accommodation cavity 10a (the side where the front plate 12 is located). The movable baffle 20 no longer forms an obstruction in the forward direction of the pool cleaning robot 200, that is, the towing mechanism 100 no longer receives a pushing force in the forward direction. The movable baffle 20 rotates to the second state to open the opening 10b, and the pool cleaning robot 200 enters the accommodation cavity 10a through the opening 10b.

[0056] In summary, a water-off base station 1000 provided by the present application includes a base station main body 300 and a towing mechanism 100; the towing mechanism 100 is movably connected to the base station main body 300, and the towing mechanism 100 is used to tow the pool cleaning robot 200 ashore or send the pool cleaning robot 200 into the pool. The towing mechanism 100 includes a towing main body 10 and a movable baffle 20. The towing main body 10 includes a bottom plate 14 and two side plates provided on both sides of the bottom plate 14. The bottom plate 14 and the two side plates enclose an accommodation cavity 10a for accommodating the pool cleaning robot 200, and at least one end of the accommodation cavity 10a is provided with an opening 10b; the movable baffle 20 is provided at the opening 10b and is rotatably connected to the two side plates. When the movable baffle 20 contacts the pool cleaning robot 200, it can rotate under the action of the pool cleaning robot 200 to open the opening 10b, and the movable baffle 20 can move towards the inside of the accommodation cavity 10a under the action of the pool cleaning robot 200.

[0057] After the pool cleaning robot 200 finishes the cleaning task, the pool cleaning robot 200 moves to the position where the towing mechanism 100 is located. The pool cleaning robot 200 contacts the movable baffle 20 and opens the opening 10b to achieve automatic unlocking and enter the accommodation cavity 10a of the towing mechanism 100. Generally, when the pool cleaning robot 200 contacts the movable baffle 20, if the friction force of the pool wall M1 is large, the pool cleaning robot 200 will continuously apply a force to the entire towing mechanism 100, and this force may cause the towing mechanism 100 to be lifted up, resulting in a failure to align with the pile. If the friction force of the pool wall M1 is insufficient, the pool cleaning robot 200 will slip in place or stay still until the baffle 20 is opened by a certain angle through the crawler wheels. In this application, it is designed that while the movable baffle 20 rotates, it can move towards the accommodation cavity 10a under the action of the pool cleaning robot 200, so that the pool cleaning robot 200 can continue to move forward after contacting the movable baffle 20, avoiding the pool cleaning robot 200 from lifting the towing mechanism 100 upwards or pushing it out and deviating from the direction of the pool wall M1, keeping the towing mechanism 100 in contact with the pool wall M1, or avoiding the pool cleaning robot 200 staying in place for a while and only being able to move forward after the movable baffle 20 is opened downwards, promoting the smooth return of the pool cleaning robot 200 to the pile.

[0058] The above process does not require manually putting the pool cleaning robot 200 into the water and taking it out of the water. The pool cleaning robot 200 can be taken out in time when the pool cleaning robot 200 finishes the cleaning task, reducing the risk of the pool cleaning robot 200 having its service life reduced due to being soaked in water for a long time, making the use of the pool cleaning robot 200 more convenient.

[0059] Please refer to Figures 6a - 8b , in an optional implementation manner of the first movable baffle 20, a rotating chute 113 is provided at a position of the side plate close to the opening 10b.

[0060] Please refer to Figure 9 , the movable baffle 20 includes a baffle main body 22, a swing arm 21 and a rotating shaft 23 connected in sequence. Further optionally, the baffle main body 22, the swing arm 21 and the rotating shaft 23 are an integral structural member.

[0061] The baffle main body 22 extends along the width direction.

[0062] Please refer to Figures 6a - 8b , the rotating shaft 23 is arranged in the rotating chute 113, and the rotating shaft 23 can rotate and slide in the rotating chute 113.

[0063] Please refer to Figures 4 - 6b, both ends of the swing arm 21 are respectively connected to the baffle main body 22 and the rotating shaft 23. Further optionally, the axial direction of the rotating shaft 23 is the width direction. The extending direction of the swing arm 21 is perpendicular or nearly perpendicular to the extending direction of the baffle main body 22. The extending direction of the swing arm 21 is perpendicular or nearly perpendicular to the extending direction of the rotating shaft 23. In the width direction, the rotating shaft 23 and the baffle main body 22 are respectively arranged on both sides of the swing arm 21.

[0064] When the baffle main body 22 contacts the pool cleaning robot 200, it can push the rotating shaft 23 to slide in the rotating chute 113.

[0065] Optionally, during the process of the pool cleaning robot 200 entering the accommodating cavity 10a from the outside, when the pool cleaning robot 200 contacts the outer wall of the baffle main body 22, it has a pushing force towards the accommodating cavity 10a and a rotating force towards the pool wall M1 on the baffle main body 22. Based on this, when the baffle main body 22 contacts the pool cleaning robot 200, under the action of the pushing force, it can push the rotating shaft 23 to slide towards the inside of the accommodating cavity 10a in the rotating chute 113, avoiding the towing main body 10 being lifted upwards or pushed out and deviating from the direction of the pool wall M1, or avoiding the pool cleaning robot 200 slipping in place or not moving, and it can only continue to move forward after the movable baffle 20 is opened downwards.

[0066] Optionally, the extending direction of the rotating chute 113 is consistent with the traveling direction of the pool cleaning robot 200 entering the accommodating cavity 10a from the opening 10b.

[0067] Specifically, the extending direction of the rotating chute 113 can be consistent with the advancing direction of the pool cleaning robot 200 entering the accommodating cavity 10a from the opening 10b, so that the force of the pool cleaning robot 200 loaded onto the towing mechanism 100 towards the advancing direction can efficiently drive the rotating shaft 23 of the movable baffle 20 to slide along the rotating chute 113, and the chute of the rotating chute 113 will not generate sliding resistance in other directions on the rotating shaft 23, avoiding the pushing force in the traveling direction of the pool cleaning robot 200 entering the accommodating cavity 10a from the opening 10b from acting on the towing main body 10.

[0068] In other embodiments, the extending direction of the rotating chute 113 can also be a direction having a certain angle with the traveling direction of the pool cleaning robot 200 entering the accommodating cavity 10a from the opening 10b. In this way, during the process of the movable baffle 20 sliding along the rotating chute 113, there is a sliding displacement in the traveling direction of the pool cleaning robot 200 entering the accommodating cavity 10a from the opening 10b, avoiding the abutting force in the traveling direction of the pool cleaning robot 200 entering the accommodating cavity 10a from the opening 10b acting on the towing main body 10. When the movable baffle 20 and the towing main body 10 cannot yield, the pool cleaning robot 200 will not be able to move forward, that is, it will slip in place until the movable baffle 20 is pressed down to a certain angle before it can continue to move forward; or, it may cause abnormal movement of the contact towing mechanism 100, such as the contact towing mechanism 100 being lifted upward or pushed out and deviating from the direction of the pool wall M1, resulting in the pool cleaning robot 200 being unable to enter the towing mechanism 100, that is, the towing mechanism 100 fails to dock with the pile.

[0069] Optionally, please refer to Figures 6a - 8b , the rotating chute 113 has a first end 113a and a second end 113b.

[0070] The first end 113a is close to the opening 10b. The second end 113b is far from the opening 10b. In other words, the second end 113b is closer to the front plate 12 than the first end 113a, and the first end 113a is farther from the front plate 12 than the second end 113b.

[0071] When the rotating shaft 23 is located at the first end 113a, the movable baffle 20 closes the opening 10b.

[0072] When the rotating shaft 23 is located at the second end 113b, the movable baffle 20 opens the opening 10b.

[0073] In this embodiment, during the process of the movable baffle 20 rotating from the first state of closing the opening 10b to the second state of opening the opening 10b under the action of the pool cleaning robot 200, the baffle main body 22 drives the rotating shaft 23 to move from the end close to the opening 10b of the rotating chute 113 towards the end far from the opening 10b of the accommodating cavity 10a.

[0074] Further optionally, please refer to Figures 6a - 8b , the movable baffle 20 further includes an elastic reset member 26.

[0075] One end of the elastic reset member 26 is connected to the rotating shaft 23, and the other end of the elastic reset member 26 is connected to the side plate.

[0076] The elastic deformation amount of the elastic reset member 26 when the rotating shaft 23 is located at the first end 113a is less than the elastic deformation amount of the elastic reset member 26 when the rotating shaft 23 is located at the second end 113b.

[0077] The elastic reset member 26 is used to generate elastic deformation when the rotating shaft 23 moves and rotates from the first end 113a to the second end 113b, so that when the pool cleaning robot 200 no longer exerts a force on the movable baffle 20, or the force exerted by the pool cleaning robot 200 on the movable baffle 20 is less than the deformation recovery force of the elastic reset member 26, the elastic reset member 26 drives the rotating shaft 23 to move and rotate back to the first end 113a under the deformation recovery force, that is, after the pool cleaning robot 200 enters the accommodation cavity 10a, the movable baffle 20 rotates from the second state of opening the opening 10b to the first state of closing the opening 10b under the action of the elastic reset member 26, so that the movable baffle 20 blocks the rear end of the pool cleaning robot 200 during the subsequent movement of the towing mechanism 100, preventing the pool cleaning robot 200 from falling out of the accommodation cavity 10a.

[0078] For example, the elastic reset member 26 includes, but is not limited to, an elastic structure. The elastic reset member 26 includes, but is not limited to, an elastic metal member, or an elastic rubber member, or a gas spring, etc. The elastic metal member includes, but is not limited to, a spring, or a spring sheet, or an elastic clip, or an elastic cord, etc. The spring includes, but is not limited to, a tension spring, or a compression spring, etc.

[0079] In an alternative embodiment, please refer to Figures 6a - 8b , the elastic reset member 26 is a tension spring. The first end 113a of the tension spring is fixedly connected to the side plate, and the second end 113b of the tension spring is connected to the rotating shaft 23.

[0080] Specifically, the elastic tensile amount of the elastic reset member 26 when the rotating shaft 23 is located at the first end 113a is less than the elastic tensile amount of the elastic reset member 26 when the rotating shaft 23 is located at the second end 113b.

[0081] The elastic reset member 26 is used to generate an elastic tensile deformation when the rotating shaft 23 moves and rotates from the first end 113a to the second end 113b, so that when the pool cleaning robot 200 no longer exerts a force on the movable baffle 20, or the force exerted by the pool cleaning robot 200 on the movable baffle 20 is less than the tensile deformation recovery force of the elastic reset member 26, the elastic reset member 26 drives the rotating shaft 23 to move and rotate back to the first end 113a under the tensile deformation recovery force. That is, after the pool cleaning robot 200 enters the accommodation cavity 10a, the movable baffle 20 rotates from the second state of opening the opening 10b to the first state of closing the opening 10b under the action of the elastic reset member 26, so that the movable baffle 20 blocks the rear end of the pool cleaning robot 200 during the subsequent movement of the towing mechanism 100, avoiding the pool cleaning robot 200 from falling out of the accommodation cavity 10a.

[0082] Further optionally, please refer to Figure 7a and Figure 7b , when the rotating shaft 23 is located at the first end 113a, the tension spring is in the first tensile state, and the lifting force of the tension spring on the rotating shaft 23 keeps the movable baffle 20 in the position of the first state.

[0083] Please refer to Figure 8a and Figure 8b , when the rotating shaft 23 is located at the second end 113b, the tension spring is in the second tensile state. The tensile length in the second tensile state is greater than the tensile length in the first tensile state, so that the elastic tensile amount of the elastic reset member 26 when the rotating shaft 23 is located at the first end 113a is less than the elastic tensile amount of the elastic reset member 26 when the rotating shaft 23 is located at the second end 113b.

[0084] Further optionally, the first end 113a of the tension spring is located closer to the first end 113a of the rotating chute 113 and farther from the bottom plate 14. Specifically, the distance between the first end 113a of the tension spring and the first end 113a of the rotating chute 113 is less than the distance between the first end 113a of the tension spring and the second end 113b of the rotating chute 113. The distance between the first end 113a of the tension spring and the bottom plate 14 is less than the distance between the second end 113b of the tension spring and the bottom plate 14.

[0085] In this way, in this embodiment, when the rotating shaft 23 is located at the first end 113a, the tension spring has a lifting force on the rotating shaft 23 away from the bottom plate 14 and a pulling force away from the second end 113b of the rotating chute 113, keeping the movable baffle 20 in the position of the first state.

[0086] Moreover, in the present embodiment, the rotating shaft 23 rotates from the first end 113a (when the baffle main body 22 is in the first state) towards the side where the bottom plate 14 is located (when the baffle main body 22 is in the second state), the tension spring is stretched, and the tension spring generates a rotational torque that causes the rotating shaft 23 to rotate back, so that when the pool cleaning robot 200 no longer exerts a force on the movable baffle 20, or when the force exerted by the pool cleaning robot 200 on the movable baffle 20 is less than the restoring force of the stretched deformation of the tension spring, the tension spring drives the rotating shaft 23 to rotate back to the state where the baffle main body 22 is in the first state.

[0087] Meanwhile, in the present embodiment, the rotating shaft 23 moves from the first end 113a towards the second end 113b, the tension spring is stretched, and the tension spring generates a stretched deformation that causes the rotating shaft 23 to move back, so that when the pool cleaning robot 200 no longer exerts a force on the movable baffle 20, or when the force exerted by the pool cleaning robot 200 on the movable baffle 20 is less than the restoring force of the stretched deformation of the tension spring, the tension spring drives the rotating shaft 23 to move back to the first end 113a.

[0088] Further optionally, please refer to Figures 6a to 7b , when the rotating shaft 23 is located at the first end 113a, the extending direction of the swing arm 21 is parallel to the extending direction of the side plate. On the one hand, the movable baffle 20 is in the first state of closing the opening 10b. At this time, the height of the baffle main body 22 is the same as or close to the center height of the traveling wheels of the pool cleaning robot 200, so that when the traveling wheels 250 of the pool cleaning robot 200 contact the outer side wall of the baffle main body 22, the center line position of the traveling wheels 250 of the pool cleaning robot 200 abuts against the center line position of the baffle main body 22, increasing the friction transmission efficiency between the traveling wheels 250 of the pool cleaning robot 200 and the outer side wall of the baffle main body 22, and facilitating the baffle main body 22 to move towards the side where the bottom plate 14 is located as the traveling wheels 250 of the pool cleaning robot 200 rotate.

[0089] Please refer to Figure 5 , Figure 8a and Figure 8b , when the rotating shaft 23 is located at the second end 113b, the extending direction of the swing arm 21 is perpendicular to the extending direction of the side plate.

[0090] When the movable baffle 20 is in the second state, opening the opening 10b, the baffle body 22 is located on the side of the base plate 14 of the towing body 10. Optionally, the swing arm 21 extends perpendicularly to the direction of extension of the side plate and parallel to the normal of the base plate 14. The baffle body 22 is positioned adjacent to and side by side with the base plate 14. Furthermore, the inner sidewall of the baffle body 22 may be slightly lower than the surface of the base plate 14 (the bottom wall of the accommodating chamber 10a), allowing the baffle body 22 to serve as a step for the pool cleaning robot 200 to climb from the pool wall M1 onto the surface of the base plate 14 (the bottom wall of the accommodating chamber 10a), assisting the pool cleaning robot 200 in climbing from the pool wall M1 onto the base plate 14. Furthermore, the outer sidewall of the baffle body 22 is in contact with or spaced apart from the pool wall M1 to prevent interference between the movable baffle 20 and the pool wall M1 when the movable baffle 20 is in the second state, opening the opening 10b.

[0091] Alternatively, the movable baffle 20 may include two swing arms 21, each connected to one end of the baffle body 22. The two swing arms 21 are symmetrically arranged about the baffle body 22. The movable baffle 20 also includes two rotation shafts 23, each located on a side of the two swing arms 21 away from the baffle body 22.

[0092] There are also two rotating chutes 113 , which are respectively provided at a position close to the opening 10 b of the first side plate 11 and a position close to the opening 10 b of the second side plate 13 . The two rotating chutes 113 are symmetrically distributed.

[0093] There are also two elastic return members 26. One elastic return member 26 is connected to the rotation shaft 23 on the side of the first side plate 11 and the first side plate 11. The other elastic return member 26 is connected to the rotation shaft 23 on the side of the second side plate 13 and the second side plate 13. The two elastic return members 26 are also symmetrically distributed.

[0094] See also Figure 6a and Figure 6b The first side panel 11 comprises a first sub-side panel 11a and a second sub-side panel 11b, which interlock to form a complete side panel. The second sub-side panel 11b is located on the side of the first sub-side panel 11a facing away from the bottom panel 14. A first side panel cavity 11c is defined on the side of the first sub-side panel 11a facing the second sub-side panel 11b. A rotational slot 113 is formed on the first sub-side panel 11a and communicates with the first side panel cavity 11c. The rotational shaft 23 extends through the rotational slot 113.

[0095] See also Figures 7a - 8b, a connecting block 27 is provided at one end of the rotating shaft 23 away from the swing arm 21, and the extending direction of the connecting block 27 is the same as that of the swing arm 21. One end of the connecting block 27 is integrally interconnected with a part of the peripheral side wall of the end of the rotating shaft 23 away from the swing arm 21, and the other end of the connecting block 27 extends toward the side away from the front plate 12. The other end of the connecting block 27 is connected to the second end 113b of the elastic reset member 26.

[0096] Further, the extending length of the connecting block 27 is less than the extending length of the rotating chute 113, so that the connecting block 27 can be installed into the first side plate cavity 11c along the width direction from the opening 10b through the rotating chute 113. Wherein, a U-shaped structure is formed among the connecting block 27, the rotating shaft 23 and the swing arm 21, and a part of the U-shaped structure passes through the rotating chute 113 and is engaged with the first sub-side plate 11a, so that the rotating shaft 23 is reliably fixed in the rotating chute 113.

[0097] Optionally, please refer to Figures 7a - 8b , a limiting member 114 is provided outside the rotating chute 113 to limit the position of the movable baffle 20 when opening and closing the opening 10b, so that when the rotating shaft 23 is located at the first end 113a, the extending direction of the swing arm 21 is parallel to the extending direction of the side plate, and the first state of the movable baffle 20 closing the opening 10b is limited; when the rotating shaft 23 is located at the second end 113b, the extending direction of the swing arm 21 is perpendicular to the extending direction of the side plate, and the second state of the movable baffle 20 opening the opening 10b is limited.

[0098] In an optional implementation manner of the first limiting member 114, please refer to Figures 7a - 8b , the limiting member 114 surrounds a part of the peripheral side of the rotating chute 113. A notch 115 is formed outside the rotating chute 113 that is not surrounded by the limiting member 114. The rotating shaft 23 can rotate within the area defined by the notch 115.

[0099] Specifically, the limiting member 114 protrudes from the cavity wall of the first side plate cavity 11c of the first sub-side plate 11a. The limiting member 114 is generally in the shape of an arc plate. The arc plate surrounds a part of the peripheral side of the rotating chute 113. A notch 115 communicating with the rotating chute 113 is formed outside the rotating chute 113 that is not surrounded by the limiting member 114, and the connecting block 27 of the rotating shaft 23 can rotate within the area defined by the notch 115. When the connecting block 27 of the rotating shaft 23 abuts against one end of the limiting member 114, the rotating shaft 23 is located at the first end 113a, the extending direction of the swing arm 21 is parallel to the extending direction of the side plate, and the movable baffle 20 is in the first state of closing the opening 10b.

[0100] When the connecting block 27 of the rotating shaft 23 abuts against the other end of the limiting member 114, the rotating shaft 23 is located at the second end 113b, the extending direction of the swing arm 21 is perpendicular to the extending direction of the side plate, and the movable baffle 20 is in the second state of opening the opening 10b.

[0101] In an alternative embodiment of the second limiting member 114, please refer to Figure 4 and Figure 5 , the first side plate 11 has a rotating groove 11d near the opening 10b. The swing arm 21 rotates within the rotating groove 11d. The rotating groove 11d has a first groove side wall 111 and a second groove side wall 112 that intersect. The limiting member 114 includes the first groove side wall 111 and the second groove side wall 112.

[0102] Please refer to Figure 4 , when the swing arm 21 rotates to abut against the first groove side wall 111, the rotating shaft 23 is located at the first end 113a, the extending direction of the swing arm 21 is parallel to the extending direction of the side plate, and the movable baffle 20 is in the first state of closing the opening 10b.

[0103] Please refer to Figure 5 , when the swing arm 21 rotates to abut against the second groove side wall 112, the rotating shaft 23 is located at the second end 113b, the extending direction of the swing arm 21 is perpendicular to the extending direction of the side plate, and the movable baffle 20 is in the second state of opening the opening 10b.

[0104] Further optionally, the first groove side wall 111 faces the side where the bottom plate 14 is located. Further, the plane of the first groove side wall 111 is parallel or nearly parallel to the plane of the bottom plate 14.

[0105] Further optionally, the second groove side wall 112 faces away from the side where the front plate 12 is located. Further, the plane of the second groove side wall 112 is perpendicular or nearly perpendicular to the plane of the bottom plate 14.

[0106] The first groove side wall 111 is located on the side of the second groove side wall 112 away from the front plate 12. The second groove side wall 112 is connected to the end face of the bottom plate 14 away from the front plate 12. Thus, when the movable baffle 20 is in the first state, the baffle body 22 is adjacent to or in contact with the bottom plate 14, so that the opening 10b is completely opened.

[0107] Further, the thickness of the swing arm 21 is less than the depth of the rotating groove 11d, that is, the swing arm 21 is always located within the rotating groove 11d during rotation, so as to avoid movement interference when the swing arm 21 protrudes from the rotating groove 11d for the pool cleaning robot 200 to enter and exit the accommodation cavity 10a.

[0108] In an alternative embodiment of the second movable baffle 20, refer to Figure 10 and Figure 11 , the movable baffle 20 includes a baffle body 22, a swing arm 21 and a rotating shaft 23.

[0109] The rotating shaft 23 is provided on the side plate. The rotating shaft 23 is rotatably connected to the side plate. The rotating shaft 23 is arranged in the width direction, and the extending direction of the swing arm 21 is perpendicular to the extending direction of the rotating shaft 23.

[0110] The difference between this embodiment and the alternative embodiment of the first movable baffle 20 is that the rotating groove 11d for the rotating shaft 23 to pass through on the side plate can be a circular hole. The rotating shaft 23 rotates relative to the side plate without moving towards the accommodating cavity 10a relative to the side plate.

[0111] The difference between this embodiment and the alternative embodiment of the first movable baffle 20 is that, refer to Figure 10 and Figure 11 , the swing arm 21 includes a fixed arm 214 and a telescopic arm 212 that can telescopically move relative to the fixed arm 214. The telescopic arm 212 is connected to the baffle body 22. The fixed arm 214 is connected to the rotating shaft 23.

[0112] Further, the fixed arm 214 and the telescopic arm 212 have a certain telescopic space in their connection direction.

[0113] Further optionally, refer to Figure 10 and Figure 11 , the swing arm 21 further includes a telescopic elastic member 213 elastically connected between the fixed arm 214 and the telescopic arm 212. The telescopic elastic member 213 includes but is not limited to an elastic metal member, or an elastic rubber member, or a gas spring, etc. The elastic metal member includes but is not limited to a spring, or a spring sheet, or an elastic clip, or an elastic cord, etc. The spring includes but is not limited to a tension spring, or a compression spring, etc.

[0114] Refer to Figure 10 , when the rotating shaft 23 is located at the first end 113a, the swing arm 21 is in an extended state under the action of the telescopic elastic member 213, the extending direction of the swing arm 21 is parallel to the extending direction of the side plate, and the movable baffle 20 is in the first state of closing the opening 10b.

[0115] Refer to Figure 11 , when the rotating shaft 23 is located at the second end 113b, the swing arm 21 is in a shortened state under the action of the telescopic elastic member 213, the extending direction of the swing arm 21 is perpendicular to the extending direction of the side plate, and the movable baffle 20 is in the second state of opening the opening 10b.

[0116] During the rotation process, the baffle main body 22 can move towards the accommodation cavity 10a under the action of the pool cleaning robot 200. That is, the baffle main body 22 can rotate and move towards the accommodation cavity 10a (the side where the front plate 12 is located) synchronously. So that when the pool cleaning robot 200 contacts the baffle main body 22, it has a pushing force in the forward direction on the baffle main body 22. The baffle main body 22 can move towards the accommodation cavity 10a (the side where the front plate 12 is located) under the action of the pushing force in the forward direction, avoiding the towing main body 10 from being lifted upward or pushed out and deviating from the direction of the pool wall M1, or avoiding the pool cleaning robot 200 from slipping in place or not moving, and can continue to move forward only after the movable baffle 20 is opened downward; in addition, when the pool cleaning robot 200 contacts the baffle main body 22, it also has a rotating force downward (towards the pool wall M1) on the baffle main body 22. While moving towards the accommodation cavity 10a (the side where the front plate 12 is located), the baffle main body 22 rotates towards the pool wall M1 side. The baffle main body 22 no longer forms an obstruction in the forward direction of the pool cleaning robot 200, that is, the towing mechanism 100 no longer receives a pushing force in the forward direction, and the movable baffle 20 rotates to the second state to open the opening 10b, and the pool cleaning robot 200 enters the accommodation cavity 10a through the opening 10b.

[0117] In a second aspect, please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a pool cleaning system 2000. The pool cleaning system 2000 includes a pool cleaning robot 200 and the water separation base station 1000 described in any of the foregoing embodiments. The pool cleaning robot 200 is located in the accommodation cavity 10a of the towing mechanism 100. The water separation base station 1000 is used to tow the pool cleaning robot 200 ashore or send the pool cleaning robot 200 into the pool.

[0118] The following specifically illustrates the structure of the pool cleaning robot 200, how the pool cleaning robot 200 opens the movable baffle 20 by itself, enters the accommodation cavity 10a (returns to the pile), and the movable baffle 20 closes the opening 10b, etc.

[0119] Further optionally, please refer to Figure 12 , the pool cleaning robot 200 includes traveling wheels 250. The traveling wheels 250 include a crawler 210 and a first crawler wheel 220 and a second crawler wheel 230 provided in the crawler 210. The first crawler wheel 220 and the second crawler wheel 230 rotate to drive the crawler 210 to rotate clockwise or counterclockwise, so that the pool cleaning robot 200 moves forward or backward.

[0120] The pool cleaning robot 200 further includes a crawler drive assembly (not shown). The crawler drive assembly is used to drive the first crawler wheel 220 and the second crawler wheel 230 to rotate, so as to drive the crawler 210 to rotate clockwise or counterclockwise, and make the pool cleaning robot 200 move forward or backward.

[0121] Further, the pool cleaning robot 200 further includes a water pump (not shown). When the water pump works, it sprays water towards the pool cleaning robot 200 to generate a pressing force that presses the bottom of the pool cleaning robot 200 from the top, so that the bottom of the pool cleaning robot 200 closely adheres to the pool wall M1 or the pool bottom. Under the traction of the traveling wheels 250, the bottom of the pool cleaning robot 200 closely adheres to the pool wall M1 or the pool bottom and moves forward.

[0122] During the process that the pool cleaning robot 200 climbs the pool wall M1 and enters the accommodation cavity 10a, the crawler drive assembly is used to drive the crawler 210 to rotate in the first rotation direction. Wherein, the first rotation direction is that the front crawler 210 continuously moves towards the pool wall M1 side, and the rear crawler 210 continuously moves from the pool wall M1 side towards the top side of the pool cleaning robot 200.

[0123] The water pump is in a working state, so that the bottom of the pool cleaning robot 200 closely adheres to the pool wall M1.

[0124] The pool cleaning robot 200 climbs the pool wall M1 and moves until the front crawler 210 of the pool cleaning robot 200 contacts the outer wall of the movable baffle 20 (baffle main body 22). The crawler 210 drives the movable baffle 20 to rotate towards the bottom plate 14 through friction transmission or meshing transmission, and the movable baffle 20 moves from the first state to the second state.

[0125] During this process, since the movable baffle 20 can move towards the accommodation cavity 10a under the action of the pool cleaning robot 200 during the rotation process, when the crawler 210 of the pool cleaning robot 200 contacts the movable baffle 20, it has a pushing force in the forward direction and a rotational torque towards the bottom plate 14 side on the movable baffle 20. The movable baffle 20 can move towards the accommodation cavity 10a (the side where the front plate 12 is located) under the action of the pushing force in the forward direction, so as to prevent the towing main body 10 from being lifted up or pushed out and deviating from the direction of the pool wall M1, or prevent the pool cleaning robot 200 from slipping in place or not moving, and it can only continue to move forward after the movable baffle 20 is opened downward; the movable baffle 20 rotates under the rotational torque towards the bottom plate 14 side, and the movable baffle 20 moves from the first state to the second state.

[0126] The water pump is in a working state, and the pressure generated by the water pump on the movable baffle 20 is greater than the restoring force of the movable baffle 20 from the second state to the first state. That is, the pressure generated by the water pump on the movable baffle 20 is greater than the restoring force of the elastic resetting member 26. Therefore, the movable baffle 20 is in a fully depressed state (second state). Since the water jet from the water pump nozzle when the pool cleaning robot 200 climbs the wall causes the pool cleaning robot 200 to exert a pressure on the wall, this pressure can ensure that the pool cleaning robot 200 always overcomes the restoring force of the elastic resetting member 26, presses down the movable baffle 20, and uses the baffle body 22 of the movable baffle 20 as a transition until the pool cleaning robot 200 completely enters the towing mechanism 100.

[0127] Optionally, please refer to Figure 12 , a plurality of first protrusions 211 are provided on the outer surface of the crawler 210. The first protrusions 211 include but are not limited to bump dots or convex strips, etc. In this embodiment, the first protrusions 211 are convex strips. The first protrusions 211 extend along the width direction X.

[0128] Please refer to Figure 12 , a plurality of second protrusions 24 are provided on the surface of the movable baffle 20 facing away from the receiving cavity 10a. The second protrusions 24 include but are not limited to bump dots or convex strips, etc. In this embodiment, the second protrusions 24 are convex strips. The second protrusions 24 extend along the width direction X.

[0129] When the crawler 210 contacts the surface (outer side wall) of the movable baffle 20 facing away from the receiving cavity 10a and the crawler 210 advances towards the inside of the receiving cavity 10a, at least part of the first protrusions 211 engages with at least part of the second protrusions 24 to increase the friction between the crawler 210 and the movable baffle 20, facilitating the crawler 210 to more easily drive the movable baffle 20 to rotate, so as to enable the pool cleaning robot 200 to open the opening 10b by itself. The movable baffle 20 moves from the first state to the second state under the action of the crawler 210.

[0130] Please refer to Figures 13 - 15 , when the pool cleaning robot 200 enters the receiving cavity 10a and reaches the set limit or travels to a certain position, the rear end of the crawler 210 of the pool cleaning robot 200 no longer contacts the movable baffle 20. That is, when the pool cleaning robot 200 is located inside the receiving cavity 10a, the tail end of the crawler 210 is separated from the baffle body 22 of the movable baffle 20. The movable baffle 20 no longer receives the downward pressure from the pool cleaning robot 200. The movable baffle 20 rotates to the first state under the restoring force of the elastic resetting member 26. The movable baffle 20 closes the opening 10b to prevent the pool cleaning robot 200 from falling out of the towing mechanism 100.

[0131] Optionally, during the lifting process of the towing mechanism 100, the crawler 210 is in a stopped rotation state and the water pump stops working. As the pool cleaning robot 200 gradually leaves the water surface, the pool cleaning robot 200 slightly descends under the action of gravity, and the rear end of the crawler 210 contacts the baffle main body 22. The baffle main body 22 is used to support the rear end of the pool cleaning robot 200 to prevent the pool cleaning robot 200 from leaving the towing mechanism 100 until the pool cleaning robot 200 completely comes ashore.

[0132] Further, the center line of the crawler 210 of the pool cleaning robot 200 is aligned with the center line of the baffle main body 22, so that the supporting force of the baffle main body 22 on the rear end of the pool cleaning robot 200 is directly opposite to the pool cleaning robot 200, preventing the pool cleaning robot 200 from tilting and falling in the accommodation cavity 10a.

[0133] Since the acting force of the pool cleaning robot 200 on the baffle main body 22 approximately passes through the axis of the baffle main body 22 during the process of coming ashore and the crawler 210 does not rotate, the baffle main body 22 will not rotate to cause the unlocking of the pool cleaning robot 200.

[0134] Optionally, please refer to Figure 16 and Figure 17 , when the pool cleaning robot 200 is in the accommodation cavity 10a, during the rotation process of the movable baffle 20 from the second state to the first state, it is spaced from the pool cleaning robot 200 to avoid position interference between the movable baffle 20 and the pool cleaning robot 200 during the rotation process, resulting in the problem that the movable baffle 20 cannot rotate to the first state or the second state.

[0135] Optionally, the movement trajectory of the movable baffle 20 from the first state to the second state is an arc trajectory. The rotation trajectory of the movable baffle 20 is close to a 1 / 4 elliptical arc.

[0136] Further optionally, please refer to Figure 16 and Figure 17 , the movable baffle 20 rotates from the first state to the second state by rotating around the 1 / 4 arc crawler 210 of the pool cleaning robot 200. Further optionally, the gap formed between the movable baffle 20 and the 1 / 4 arc crawler 210 of the pool cleaning robot 200 during the rotation process of the movable baffle 20 from the second state to the first state is a non-uniform gap. For example, during the rotation process of the movable baffle 20 from the second state to the first state, the distance between the inner surface of the movable baffle 20 and the outer surface of the crawler 210 gradually increases.

[0137] Further optionally, please refer to Figure 16 and Figure 17When the pool cleaning robot 200 is within the accommodation cavity 10a, the rotation axis center of the movable baffle 20 (hereinafter simply referred to as the first rotation axis center) when the rotation axis 23 of the movable baffle 20 is located at the second end 113b of the rotation chute 113 is concentrically arranged with the axis center of the traveling wheels 250 of the pool cleaning robot 200 (such as the aforementioned second crawler wheel 230).

[0138] Specifically, the first rotation axis center of the movable baffle 20 is the center line of the rotation axis of the swing arm 21. When viewed from the cross-section along the height direction Z and the length direction Y, the first rotation axis center of the movable baffle 20 is the central position of the rotation axis of the swing arm 21.

[0139] When viewed from the cross-section along the height direction Z and the length direction Y, the axis center of the traveling wheels 250 of the pool cleaning robot 200 (such as the aforementioned second crawler wheel 230) is located at the center position of the circle of the traveling wheels 250 of the pool cleaning robot 200 (such as the aforementioned second crawler wheel 230).

[0140] In this embodiment, when the pool cleaning robot 200 is within the accommodation cavity 10a, by concentrically arranging the first rotation axis center of the movable baffle 20 with the axis center of the traveling wheels 250 of the pool cleaning robot 200 (such as the aforementioned second crawler wheel 230), in this way, when the pool cleaning robot 200 is within the accommodation cavity 10a, the gap between the inner surface of the movable baffle 20 and the outer surface of the crawler 210 in the first state is relatively small, so the backward space when the pool cleaning robot 200 retreats to abut against the inner surface of the movable baffle 20 is small, avoiding a large distance between the front end limiting part 51 and the pool cleaning robot 200 when the pool cleaning robot 200 retreats to abut against the inner surface of the movable baffle 20, and further preventing the front end limiting part 51 from being unable to limit the front end of the pool cleaning robot 200, resulting in the pool cleaning robot 200 falling out of the accommodation cavity 10a and tipping over.

[0141] Moreover, the gap between the inner surface of the movable baffle 20 and the outer surface of the crawler 210 in the second state is small, and the height of the step surface formed by the inner surface of the movable baffle 20 and the surface of the bottom plate 14 is small, which is more conducive to the pool cleaning robot 200 crossing the movable baffle 20 and entering the accommodation cavity 10a. In addition, after the pool cleaning robot 200 completely enters the accommodation cavity 10a, the movable baffle 20 will not be subjected to the downward pressure of the traveling wheels 250 in the second state, which is conducive to the movable baffle 20 returning to the first state under the drive of the elastic resetting member 26.

[0142] Further, please refer to Figure 17 and Figure 18, the rotational short radius R2 of the inner surface 201 of the movable baffle 20 can be slightly larger than the radius R1 corresponding to the 1 / 4 circular arc track 210, so as to ensure that the movable baffle 20 will not interfere with the surface of the track 210 during rotation, and the gap is small. Furthermore, on the one hand, the size of the swing arm 21 is relatively small, and then the height and length dimensions of the size of the towing mechanism 100 are also relatively small. On the other hand, if the gap between the tail end of the pool cleaning robot 200 and the movable baffle 20 is large, it will cause a large space for the pool cleaning robot 200 to slide down in the accommodation cavity 10a, resulting in the front end of the pool cleaning robot 200 being easily separated from the front end limiting part 51 (specifically described later). Furthermore, the pool cleaning robot 200 will turn over after falling off in the accommodation cavity 10a. In this embodiment, by setting a small gap between the tail end of the pool cleaning robot 200 and the movable baffle 20, even if the space for the pool cleaning robot 200 to slide down in the accommodation cavity 10a is small, problems such as the pool cleaning robot 200 turning over after falling off in the accommodation cavity 10a are not likely to occur.

[0143] Further, please refer to Figure 17 and Figure 18 , the outer surface of the track 210 is provided with a first convex part 211, the inner surface 201 of the movable baffle 20 is provided with a third convex part 25, and the difference between the rotational short radius R2 of the movable baffle 20 and the radius R1 corresponding to the 1 / 4 circular arc track 210 refers to the distance between the end of the first convex part 211 and the end of the third convex part 25. The distance between the end of the first convex part 211 and the end of the third convex part 25 is H2.

[0144] Of course, in other embodiments, the first rotation axis of the movable baffle 20 and the axis of the traveling wheel 250 (such as the aforementioned second track wheel 230) of the pool cleaning robot 200 are not concentrically arranged. For example, the first rotation axis of the movable baffle 20 and the axis of the traveling wheel 250 (such as the aforementioned second track wheel 230) of the pool cleaning robot 200 are collinear in the length direction Y. Optionally, when the movable baffle 20 is in the first state, the connection line between the center of the baffle main body 22 and the rotation axis of the traveling wheel 250 is parallel to the bottom plate 14. In this way, when the towing mechanism 100 is attached to the pool wall M1, the pool cleaning robot 200 is in a vertical state and the tail end of the track 210 of the pool cleaning robot 200 abuts against the baffle main body 22, which can reduce the eccentricity, and further reduce problems such as the unstable falling off of the pool cleaning robot 200.

[0145] For another example, the first rotation axis of the movable baffle 20 is collinear with the axis of the traveling wheels 250 (such as the aforementioned second crawler wheel 230) of the pool cleaning robot 200 in the height direction Z. Of course, the first rotation axis of the movable baffle 20 is close to the axis of the traveling wheels 250 (such as the aforementioned second crawler wheel 230) of the pool cleaning robot 200, so that the distance between the movable baffle 20 and the 1 / 4 arc crawler 210 is close during the rotation process, reducing the risk of tipping over after falling off in the accommodation cavity 10a, and also reducing the size of the towing main body 10.

[0146] Please refer to Figure 16 , the short rotation radius R3 of the outer surface 202 of the movable baffle 20 (please refer to Figure 17 ) is less than the distance H1 between the first rotation axis of the movable baffle 20 and the back surface (pool wall M1) of the towing main body 10, thereby avoiding collision between the movable baffle 20 and the pool wall M1 when the movable baffle 20 rotates to the second state. The back surface of the towing main body 10 is arranged opposite to the bottom wall of the accommodation cavity 10a.

[0147] The short rotation radius R2 of the inner surface 201 of the movable baffle 20 (please refer to Figure 17 ) is greater than the radius R1 of the outer contour circle of the traveling wheels 250 (such as the aforementioned second crawler wheel 230) of the pool cleaning robot 200. Among them, the outer contour circle of the traveling wheels 250 (such as the aforementioned second crawler wheel 230) of the pool cleaning robot 200 refers to a circle with the projection center of the traveling wheels 250 (such as the aforementioned second crawler wheel 230) along the width direction X as the center of the circle, and with the distance between the farthest point on the corresponding 1 / 4 arc crawler 210 and the center of the circle during the rotation of the movable baffle 20 as the radius.

[0148] From another perspective, please refer to Figure 19 , when the movable baffle 20 is in the second state, the maximum distance H3 (the distance between the end point of the second convex part 24 and the end point of the third convex part 25 in the height direction Z) between the inner surface 201 and the outer surface of the movable baffle 20 is less than the minimum distance H4 between the outer surface of the crawler 210 (the end point of the first convex part 211) and the pool wall M1. In this way, the movable baffle 20 can enter the gap between the outer surface of the crawler 210 and the pool wall M1 in the second state, and avoid movement interference between the movable baffle 20 and the pool wall M1 and the outer surface of the crawler 210 when the movable baffle 20 rotates to the second state.

[0149] Please refer to Figure 19, when the movable baffle 20 rotates to the second state, it is located below the straight part of the crawler 210. There is a gap between the inner surface 201 of the movable baffle 20 and the bottom surface of the traveling wheel 250 (such as the aforementioned second crawler wheel 230) of the pool cleaning robot 200, and the movable baffle 20 will not be pressed by the straight part of the crawler 210 and thus cannot return to the first state under the action of the elastic reset member 26.

[0150] If the inner surface 201 of the movable baffle 20 is flush with the surface of the bottom plate 14 of the pool cleaning robot 200 (the bottom wall of the accommodation cavity 10a), since the movable baffle 20 is located below the straight part of the crawler 210 when it rotates to the second state, it will be pressed by the straight part of the crawler 210, resulting in the movable baffle 20 being unable to return to the first state under the action of the elastic reset member 26. If the movable baffle 20 wants to be successfully reset from the second state under the action of the elastic reset member 26, it is necessary to move the position of the movable baffle 20 in the second state to below the arc surface corresponding to the crawler 210. In this way, even when the movable baffle 20 is reset to the first state, the distance between the baffle main body 22 and the crawler 210 will be relatively large. On the one hand, it will cause the length of the entire towing main body 10 to increase, and on the other hand, it will cause the pool cleaning robot 200 to have a large sliding space in the accommodation cavity 10a, resulting in the front end of the pool cleaning robot 200 being easily separated from the front end limiting portion 51 (to be specifically described later), and then the pool cleaning robot 200 will fall and turn over in the accommodation cavity 10a; in this embodiment, by setting a small gap between the tail end of the pool cleaning robot 200 and the movable baffle 20, even if the pool cleaning robot 200 has a small sliding space in the accommodation cavity 10a, problems such as the pool cleaning robot 200 falling and turning over in the accommodation cavity 10a are not likely to occur.

[0151] Optionally, please refer to Figure 12 , the outer contour of the baffle main body 22 is arc-shaped. Optionally, the outer side wall of the baffle main body 22 is arc-shaped. For example, when the pool cleaning robot 200 contacts the outer side wall of the baffle main body 22 in the first state outside the accommodation cavity 10a, the crawler 210 of the pool cleaning robot 200 first contacts the bottom end (the third convex portion 25) of the outer side wall of the baffle main body 22. As the pool cleaning robot 200 moves forward, the pool cleaning robot 200 presses down the baffle main body 22 (rotates downward by a certain angle). The outer side wall of the baffle main body 22 is also arc-shaped, so that the pool cleaning robot 200 can gradually contact the top end (the third convex portion 25) of the outer side wall of the baffle main body 22 after the baffle main body 22 rotates downward by a certain angle.

[0152] Optionally, please refer to Figures 13 to 15, the towing mechanism 100 includes a front end limiting portion 51. The front end limiting portion 51 is provided on the towing main body 10 and is disposed opposite to the opening 10b. Specifically, the front end limiting portion 51 is provided on the front plate 12. When the pool cleaning robot 200 moves into the accommodating cavity 10a, the front end limiting portion 51 cooperates with the movable baffle 20 to limit the pool cleaning robot 200. Further, the front end limiting portion 51 and the movable baffle 20 cooperate to limit the pool cleaning robot 200 in the traveling direction (front-back direction) and the height direction Z, so that the pool cleaning robot 200 can be stably constrained within the accommodating cavity 10a.

[0153] Specifically, the orthographic projection of the front end limiting portion 51 on the plane where the bottom plate 14 is located is at least partially located on the bottom plate 14, so at least a part of the front end limiting portion 51 protrudes from the front plate 12. Further, an inward concave space is formed between the front end limiting portion 51, the front plate 12, and the bottom plate 14 to accommodate the front end of the pool cleaning robot 200. At least a part of the front end limiting portion 51 is located on the top side of the front end of the pool cleaning robot 200, and the front end limiting portion 51 and the bottom plate 14 cooperate to limit the pool cleaning robot 200 in the height direction Z. The height direction Z is the direction perpendicular to the bottom plate 14.

[0154] Further, please refer to Figure 13 , when the front end of the pool cleaning robot 200 abuts against the front end limiting portion 51 and the movable baffle 20 is in the first state, the movable baffle 20 and the front end limiting portion 51 cooperate to further limit the pool cleaning robot 200 in the front-back direction. In this application, the front-back direction may also refer to the length direction Y, that is, the direction perpendicular to the front plate 12.

[0155] Further optionally, the front end limiting portion 51 can roll relative to the towing main body 10 to reduce the friction between the crawler 210 (or the walking wheel 250) and the front end limiting portion 51 when the crawler 210 (or the walking wheel 250) contacts the front end limiting portion 51 and the crawler 210 (or the walking wheel 250) is in a rotating state.

[0156] Optionally, please refer to Figures 13 - 15, the front end limiting part 51 is a roller part. The distance between the rolling axis of the front end limiting part 51 and the bottom wall of the accommodating cavity 10a (the bottom plate 14) is greater than the distance between the rotation axis 23 of the traveling wheel 250 and the bottom wall of the accommodating cavity 10a (the bottom plate 14) when the pool cleaning robot 200 is located in the accommodating cavity 10a. In this way, the front end limiting part 51 abuts against the top of the front end of the traveling wheel 250, and further, the front end limiting part 51 and the bottom plate 14 limit the pool cleaning robot 200 in the height direction Z; the front end limiting part 51 and the movable baffle 20 in the first state limit the pool cleaning robot 200 in the length direction Y.

[0157] Optionally, the front end limiting part 51 is a roller.

[0158] Optionally, please refer to Figure 4 , the bottom plate 14 is provided with a plurality of protruding parts 141. The protruding parts 141 are arranged along the direction (width direction X) in which the first side plate 11 faces the front plate 12. The protruding parts 141 are used to cooperate with the crawler 210 of the pool cleaning robot 200 when the pool cleaning robot 200 is in the accommodating cavity 10a.

[0159] Specifically, two groups of protruding parts 141 can be provided on the bottom plate 14, and the two groups of protruding parts 141 are spaced apart in the width direction X. Each group of protruding parts 141 includes a plurality of protruding parts 141. The plurality of protruding parts 141 are arranged in sequence along the length direction Y. The protruding parts 141 are convex strips extending along the width direction X.

[0160] Each group of protruding parts 141 cooperates with one crawler 210 to increase the friction between the pool cleaning robot 200 and the bottom plate 14.

[0161] Optionally, please refer to Figure 12 , a brush roller groove 142 is provided in the area of the bottom plate 14 close to the front plate 12. The brush roller groove 142 is used to accommodate the cleaning brush roller of the pool cleaning robot 200 when the pool cleaning robot 200 is in the accommodating cavity 10a, so as to prevent the cleaning brush roller of the pool cleaning robot 200 from being deformed by being squeezed by the bottom plate 14.

[0162] Furthermore, the side of the towing mechanism 100 opposite to the bottom plate 14 is a pick-up and release port. The length direction of the accommodating chamber 10a of the towing mechanism 100 is larger than the length direction of the pool cleaning robot 200. The movable baffle 20 will not restrict the pool cleaning robot 200 from taking and placing the pool cleaning robot 200 in the direction perpendicular to the bottom plate 14, so that the pool cleaning robot 200 in the landed state can be taken out from the accommodating chamber 10a through the pick-up and release port. After the pool cleaning robot 200 is landed, it will not affect the normal taking and placing of the pool cleaning robot 200, and it can be conveniently taken away for cleaning.

[0163] When the machine is onshore, the tail hook will not restrict the machine from being detached or put back in the direction perpendicular to the contact surface of the crawler track 210 , and the user can directly take out or put in the machine.

[0164] When the pool cleaning robot 200 is launched, the towing mechanism 100 is located in a second position W2, for example, hung on the pool wall M1. The pool cleaning robot 200 is located within the accommodating chamber 10a. The track 210 of the pool cleaning robot 200 rotates in a second rotational direction, which is opposite to the first rotational direction.

[0165] Optionally, a third protrusion is provided on the inner sidewall of the baffle body 22. When the pool cleaning robot 200 is within the accommodating chamber 10a, the track 210 rotates in the second rotational direction, and the rear end of the track 210 moves to abut the inner sidewall of the baffle body 22. The first protrusion 211 of the track 210 engages with the third protrusion on the inner sidewall of the baffle body 22. The rotation of the track 210 in the second rotational direction drives the baffle body 22 toward the base plate 14. After the baffle body 22 rotates to a certain angle in the unlocking direction, the pool cleaning robot 200, under the influence of traction, gravity, and the like, passes over the baffle body 22 and falls into the water.

[0166] Alternatively, when the pool cleaning robot 200 is in the accommodating chamber 10a, the track 210 rotates about the second rotation direction, and the pool cleaning robot 200 directly passes over the baffle body 22 and falls into the water under the action of traction, gravity, etc.

[0167] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present application, and these improvements and modifications are also regarded as the scope of protection of the present application.
