Description

Technical Field

[0001] The present application relates to the field of robotics technology, and in particular to an off-water base station and a pool cleaning system. Background Art

[0002] Pool cleaning robots, as convenient automated devices, are widely used for pool cleaning and maintenance. After completing their cleaning tasks, the pool robot remains submerged in water, requiring the user to manually remove it. This process is dangerous, and prolonged immersion reduces the robot's service life. Existing pool cleaning robots require the user to manually place them in the water and remove them after use, making them inconvenient. Therefore, how to more conveniently and automatically complete operations such as returning the robot to its original position has become a technical challenge that needs to be addressed. Summary of the Invention

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

[0004] In a first aspect, an embodiment of the present application provides a water-off-water base station, the water-off-water base station comprising:

[0005] Base station body;

[0006] A towing mechanism is movably connected to the base station body, and is used to tow the pool cleaning robot ashore or send the pool cleaning robot into the pool. The towing mechanism includes:

[0007] The towing body includes a bottom plate and two side plates provided on both sides of the bottom plate, wherein the bottom plate and the two side plates enclose a receiving cavity for accommodating the pool cleaning robot, and at least one end of the receiving cavity is provided with an opening;

[0008] A movable baffle is provided at the opening and is rotatably connected to the two side panels. When the movable baffle comes into contact with the pool cleaning robot, it can be rotated under the action of the pool cleaning robot to open the opening, and the movable baffle can be moved toward the accommodating cavity under the action of the pool cleaning robot.

[0009] The present application provides an off-water base station, which includes a base station body and a towing mechanism; the towing mechanism is movably connected to the base station body, and the towing mechanism is used to tow a pool cleaning robot ashore or send the pool cleaning robot into the pool, and the towing mechanism includes a towing body and a movable baffle. The towing body includes a bottom plate and two side plates arranged on both sides of the bottom plate, and the bottom plate and the two side plates enclose a receiving chamber for accommodating the pool cleaning robot, and at least one end of the receiving chamber 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 comes into contact with the pool cleaning robot, it can be rotated under the action of the pool cleaning robot to open the opening, and the movable baffle can be moved toward the receiving chamber under the action of the pool cleaning robot;

[0010] After the pool cleaning robot finishes its cleaning task, it moves to the location of the towing mechanism, contacts the movable baffle, and opens the opening to achieve automatic unlocking, so as to enter the accommodating cavity of the towing mechanism; generally, when the pool cleaning robot contacts the movable baffle, if the friction of the pool wall is large, the pool cleaning robot will continue to apply loading force to the entire towing mechanism, and this force may cause the towing mechanism to be lifted up, resulting in failure in pile engagement; and if the friction of the pool wall is insufficient, the pool cleaning robot will slip on the spot, or stay still, until the baffle is opened to a certain angle through the track wheels. The movable baffle designed in the present application can move toward the accommodating chamber 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, preventing the pool cleaning robot from lifting the towing mechanism upward or pushing it out of the direction of the pool wall, so that the towing mechanism remains in contact with the pool wall, or preventing the pool cleaning robot from staying in place for a while and waiting until the movable baffle is opened downward before continuing to move forward, thereby promoting the pool cleaning robot to return to the pile smoothly.

[0011] The above process does not require manual putting the pool cleaning robot into the water and taking it out of the water, and the pool cleaning robot can be taken out in time when the pool cleaning robot finishes the cleaning task, reducing the risk of the pool cleaning robot's service life being reduced due to long-term immersion in water, making the pool cleaning robot more convenient to use.

[0012] In an optional embodiment, a rotating groove is provided at a position of the side panel near the opening; the movable baffle includes a baffle body, a swing arm and a rotating shaft, the rotating shaft is provided in the rotating groove, and the two ends of the swing arm are respectively connected to the baffle body and the rotating shaft, and the baffle body can push the rotating shaft to slide in the rotating groove when it contacts the pool cleaning robot.

[0013] In an optional embodiment, the extending direction of the rotating slide groove is consistent with the moving direction of the pool cleaning robot from the opening into the accommodating cavity.

[0014] In an optional embodiment, the rotating slide has a first end and a second end, the first end is close to the opening, and the second end is away from the opening. When the rotating shaft is located at the first end, the movable baffle closes the opening, and when the rotating shaft is located at the second end, the movable baffle opens the opening.

[0015] In an optional embodiment, the movable baffle further includes an elastic return member, one end of the elastic return member is connected to the rotating shaft, and the other end of the elastic return member is connected to the side plate; the elastic deformation of the elastic return member when the rotating shaft is located at the first end is smaller than the elastic deformation of the elastic return member when the rotating shaft is located at the second end.

[0016] In an optional embodiment, the elastic return member is a tension spring, a first end of the tension spring is fixedly connected to the side plate, and a second end of the tension spring is connected to the rotating shaft.

[0018] In an optional embodiment, when the rotation axis is located at the first end, the extension direction of the swing arm is parallel to the extension direction of the side plate; when the rotation axis is located at the second end, the extension direction of the swing arm is perpendicular to the extension direction of the side plate.

[0019] In an optional embodiment, a limiting member is provided on the outer side of the rotating slide groove to limit the position of the movable baffle when opening and closing the opening.

[0020] In an optional embodiment, the limiting member is arranged around a portion of the circumference of the rotating slot, and the limiting member does not surround the outer side of the rotating slot to form a gap, and the rotating shaft can rotate within the area defined by the gap.

[0021] In an optional embodiment, the movable baffle includes a baffle body, a swing arm and a rotating shaft, the rotating shaft is arranged on the side plate, the swing arm includes a fixed arm and a telescopic arm that can be extended and retracted relative to the fixed arm, the telescopic arm is connected to the baffle body, and the fixed arm is connected to the rotating shaft.

[0022] In an optional embodiment, the towing mechanism has an extended position and a retracted position. When the towing mechanism is in the retracted position, it is located on the base station body. When the towing mechanism is in the extended position, it at least partially extends below the water surface of the pool.

DETAILED DESCRIPTION

[0056] The technical solution of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments, not all embodiments. Based on the embodiments provided in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to mutually exclusive, independent, or alternative embodiments to other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0058] The terms "first," "second," and so on, in the specification and claims of this application and the accompanying drawings are used to distinguish between different objects, not to describe a specific order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a component or device comprising one or more parts is not limited to the one or more parts listed, but may optionally include one or more parts that are not listed but are inherent to the illustrated product, or one or more parts that should be present based on the described functionality.

[0059] See also Figure 1-Figure 3 , this application proposes an off-water base station 1000 for a pool cleaning robot 200 .

[0060] See also Figure 1-Figure 3 The water separation base station 1000 includes a towing mechanism 100 .

[0061] For further optional information, see Figure 1-Figure 3 The water-based base station 1000 also includes a base station body 300.

[0062] The base station body 300 is fixedly arranged on the shore of the pool, and the towing mechanism 100 is movably connected to the base station body 300. The towing mechanism 100 is used to tow the pool cleaning robot 200 from the pool to the shore, so that the pool cleaning robot 200 leaves the water surface; alternatively, the towing mechanism 100 is also used to send the pool cleaning robot 200 in the landed state into the pool to facilitate the pool cleaning robot 200 to enter the water.

[0063] See also Figure 1-Figure 3 The dragging mechanism 100 has a second position W2 and a first position W1. In other words, the dragging mechanism 100 can move to the first position W1 or the second position W2 relative to the base station body 300.

[0064] The first position W1 is a position where the towing mechanism 100 is separated from the water surface and is located on the base station body 300 .

[0065] See also Figure 1 When the towing mechanism 100 is in the first position W1, the towing mechanism 100 is located above the base station body 300, i.e., the towing mechanism 100 is in the landed state. When the pool cleaning robot 200 is placed in the accommodation cavity of the towing body, the pool cleaning robot 200 is also in the landed state.

[0066] See also Figure 2 When the towing mechanism 100 is in the second position W2, the towing mechanism 100 is at least partially 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 receiving chamber 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 a position where the towing mechanism 100 is in contact with the pool wall M1 or another position at least partially underwater, allowing the pool cleaning robot 200 to move from the pool wall M1 to the towing mechanism 100, or to enter and exit the water from the towing mechanism 100.

[0067] Optionally, the towing mechanism 100 is an expandable and retractable structure. The towing mechanism 100 has an expanded position and a retracted position. When the towing mechanism 100 is in the retracted position, it is located on the base station body 300. When the towing mechanism 100 is in the expanded position, it is at least partially submerged below the water surface of the pool.

[0068] See also Figure 4 The towing mechanism 100 includes a towing body 10 and a movable baffle 20 .

[0069] The trailer body 10 includes a base plate 14 and two side plates disposed on either side of the base plate 14. The two side plates are a first side plate 11 and a second side plate 13. The first side plate 11 and the second side plate 13 are disposed opposite each other in the width direction X. The base plate 14 is connected between the first side plate 11 and the second side plate 13.

[0070] See also Figure 4 The bottom plate 14 and the two side plates together form a receiving chamber 10a for accommodating the pool cleaning robot 200.

[0071] See also Figure 4 , at least one end of the accommodating chamber 10a is provided with an opening 10b. In this embodiment, one end of the accommodating chamber 10a along 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 arranged opposite to each other 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 the 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 accommodating chamber 10a for accommodating the pool cleaning robot 200. In other words, the towing body 10 has a accommodating chamber 10a and an opening 10b connected to the accommodating chamber 10a. The opening 10b is located between the first side plate 11 and the second side plate 13 and opposite to the front plate 12. The bottom plate 14 forms the bottom wall of the accommodating chamber 10a. The first side panel 11, the front panel 12, and the second side panel 13 respectively form three side walls of the accommodating chamber 10a. The side of the towing body 10 opposite to the bottom panel 14 may be open. The accommodating chamber 10a is used to accommodate the pool cleaning robot 200.

[0072] In other embodiments, both ends of the accommodating chamber 10a along the Y direction are openings 10b. When the pool cleaning robot 200 is placed in the accommodating chamber 10a, the bottom of the pool cleaning robot 200 engages with the bottom plate 14, allowing the pool cleaning robot 200 to be relatively fixed in the accommodating chamber 10a and to leave the water surface along with the towing mechanism 100.

[0073] The following embodiments are described by taking the towing body 10 including the front plate 12 as an example.

[0074] See also Figure 4 and Figure 5 The movable baffle 20 is rotatably connected to the towing body 10. The movable baffle 20 is provided at the opening 10b of the accommodating cavity 10a and is rotatably connected to the two side panels (i.e., the first side panel 11 and the second side panel 13). The movable baffle 20 is used to open or close the opening 10b of the towing body 10.

[0075] The movable baffle 20 is used for transmission cooperation with the pool cleaning robot 200 to be in the second state.

[0076] Specifically, 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 10 b , so that the movable baffle 20 rotates to the second state relative to the towing body 10 .

[0077] For example, the movable baffle 20 can be in direct contact with the pool cleaning robot 200, and the running wheels of the pool cleaning robot 200 rotate, thereby driving the movable baffle 20 to rotate to the second state. The second state is a state where the movable baffle 20 opens the opening 10b.

[0078] See also 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, on the side where the bottom plate 14 is located. The pool cleaning robot 200 can exit the accommodating chamber 10a through the opening 10b or enter the accommodating chamber 10a from the outside through the opening 10b.

[0079] Conventional techniques utilize electronic control components to lock the pool cleaning robot 200 within the towing mechanism 100 or to the base station 300. This approach requires numerous electronic components, resulting in a complex structural design and a degree of unreliability. Furthermore, unlocking and removing the pool cleaning robot 200 is also a limitation. If the design often incorporates self-unlocking features, the locking mechanism will be less secure and less reliable.

[0080] The present application designs a transmission cooperation between the pool cleaning robot 200 and the movable baffle 20, that is, the pool cleaning robot 200 physically interacts with the movable baffle 20, which can drive the movable baffle 20 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, without the need to set up electric drive parts and transmission parts, reducing the setting of parts and devices, and saving energy consumption. At the same time, the pool cleaning robot 200 directly contacts the movable baffle 20 to "open the door", thereby improving the reliability of unlocking.

[0081] For example, after the pool cleaning robot 200 completes its cleaning task at the pool bottom, it moves upward along the pool wall M1 until it contacts the movable baffle 20 of the towing mechanism 100. For example, the running wheels of the pool cleaning robot 200 rotate, driving the movable baffle 20 to rotate to the second state, which opens the opening 10b. The pool cleaning robot 200 enters the accommodating chamber 10a of the towing mechanism 100 through the opening 10b. After the pool cleaning robot 200 is fully inside, the movable baffle 20 closes the opening 10b, and the movable baffle 20 is in the first state. The towing mechanism 100 then moves relative to the base station body 300 to drive the pool cleaning robot 200 away from the water surface until the towing mechanism 100 is stacked on the base station body 300, i.e., the towing mechanism 100 is in the first position W1, thereby achieving automatic departure of the pool cleaning robot 200 from the pool. When the pool cleaning robot 200 is needed to perform a cleaning task, the towing mechanism 100 first moves relative to the base station body 300 to drive the pool cleaning robot 200 to move toward the water surface until the towing mechanism 100 is in contact with the pool wall M1. The towing mechanism 100 is in the second position W2, and then the movable baffle 20 opens the opening 10b to allow the pool cleaning robot 200 to fall into the water, thereby realizing automatic entry of the pool cleaning robot 200 into the water.

[0082] Furthermore, when the pool cleaning robot 200 moves upward along the pool wall M1 until it contacts the movable baffle 20 of the towing mechanism 100, and in the process of opening the movable baffle 20, the pool cleaning robot 200 continues to move forward. When the pool cleaning robot 200 contacts the movable baffle 20, it exerts a force in the forward direction on the movable baffle 20. Since the movable baffle 20 and the towing body 10 cannot retreat, the pool cleaning robot 200 will be unable to move forward, that is, it will slip in place until the movable baffle 20 is pressed down to a certain angle and can continue to move forward. The material of the pool wall M1 affects the friction of the machine. For example, on a wall with good friction, the pool cleaning robot 200 may not slip in place as described above, which may cause abnormal movement of the towing mechanism 100. For example, the towing mechanism 100 may be pushed upward or pushed out of 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 pile.

[0083] Based on the above problems, the present application is to rotate and move the movable baffle 20 toward the accommodating chamber 10a (the side where the front plate 12 is located). The pool cleaning robot 200 contacts the movable baffle 20 and exerts a resisting force on the movable baffle 20 in the forward direction. The movable baffle 20 can move toward the accommodating chamber 10a (the side where the front plate 12 is located) under the action of the resisting force in the forward direction of the pool cleaning robot 200, thereby preventing the towed body 10 from being lifted upward or pushed out of the direction of the pool wall M1. In addition, since the pool cleaning robot 200 contacts the movable baffle 20, the movable baffle 20 can move toward the accommodating chamber 10a (the side where the front plate 12 is located) under the action of the resisting force in the forward direction of the pool cleaning robot 200. While the baffle 20 is moving, it also has a downward rotational force (toward the pool wall M1) on the movable baffle 20. The movable baffle 20 moves toward the accommodating chamber 10a (on the side where the front plate 12 is located) and rotates toward the pool wall M1. The movable baffle 20 no longer forms an obstruction to the forward direction of the pool cleaning robot 200, that is, the towing mechanism 100 is no longer subjected to the resisting 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 accommodating chamber 10a through the opening 10b.

[0084] In summary, the present application provides an off-water base station 1000, which includes a base station body 300 and a towing mechanism 100; the towing mechanism 100 is movably connected to the base station 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 body 10 and a movable baffle 20. The towing body 10 includes a base plate 14 and two side plates arranged on both sides of the base plate 14. The base plate 14 and the two side plates enclose a accommodating chamber 10a for accommodating the pool cleaning robot 200. At least one end of the accommodating chamber 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 be rotated under the action of the pool cleaning robot 200 to open the opening 10b, and the movable baffle 20 can be moved toward the accommodating chamber 10a under the action of the pool cleaning robot 200.

[0085] After the pool cleaning robot 200 completes the cleaning task, the pool cleaning robot 200 moves to the location of the towing mechanism 100, and the pool cleaning robot 200 contacts the movable baffle 20 and opens the opening 10b to achieve automatic unlocking, so as to enter the accommodating 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 continue to apply loading force to the entire towing mechanism 100, and this force may cause the towing mechanism 100 to be lifted up, resulting in failure of piling; and if the friction force of the pool wall M1 is insufficient, the pool cleaning robot 200 will slip on the spot, or stay still, until the baffle 20 is opened to a certain angle through the track wheels. The movable baffle 20 designed in the present application can move toward the accommodating chamber 10a under the action of the pool cleaning robot 200 while rotating, so that the pool cleaning robot 200 can continue to move forward after contacting the movable baffle 20, preventing the pool cleaning robot 200 from lifting the towing mechanism 100 upward or pushing it out of the direction of the pool wall M1, so that the towing mechanism 100 remains in contact with the pool wall M1, or preventing the pool cleaning robot 200 from staying in place for a while and waiting until the movable baffle 20 is opened downward to continue moving forward, thereby promoting the pool cleaning robot 200 to return to the pile smoothly.

[0086] The above process does not require manual putting the pool cleaning robot 200 into the water and taking it out of the water, and 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's service life being reduced due to prolonged immersion in water, making the pool cleaning robot 200 more convenient to use.

[0087] See also Figures 6a-8b In an optional implementation of the first movable baffle 20, a rotation slot 113 is provided at a position of the side panel close to the opening 10b.

[0088] See also Figure 9 The movable baffle 20 includes a baffle body 22, a swing arm 21 and a rotation shaft 23 connected in sequence. Further optionally, the baffle body 22, the swing arm 21 and the rotation shaft 23 are an integrated structural member.

[0089] The baffle body 22 extends in the width direction.

[0090] See also Figures 6a-8b The rotating shaft 23 is disposed in the rotating slot 113 , and the rotating shaft 23 can rotate and slide in the rotating slot 113 .

[0091] See also Figure 4-6bThe ends of the swing arm 21 are connected to the baffle body 22 and the rotation shaft 23, respectively. Optionally, the axial direction of the rotation shaft 23 is the width direction. The swing arm 21 extends in a direction perpendicular or nearly perpendicular to the direction of extension of the baffle body 22. The swing arm 21 extends in a direction perpendicular or nearly perpendicular to the direction of extension of the rotation shaft 23. In the width direction, the rotation shaft 23 and the baffle body 22 are respectively disposed on either side of the swing arm 21.

[0092] When the baffle body 22 contacts the pool cleaning robot 200 , it can push the rotating shaft 23 to slide in the rotating sliding groove 113 .

[0093] Optionally, in the process of the pool cleaning robot 200 entering the accommodating chamber 10a from the outside, the pool cleaning robot 200 has a resisting force toward the accommodating chamber 10a and a rotating force toward the pool wall M1 on the baffle body 22 when contacting the outer wall of the baffle body 22. Based on this, the baffle body 22 can push the rotating shaft 23 in the rotating groove 113 to slide toward the accommodating chamber 10a under the action of the resisting force when contacting the pool cleaning robot 200, thereby preventing the towing body 10 from being lifted upward or pushed out of the direction of the pool wall M1, or preventing the pool cleaning robot 200 from slipping or staying still, and can only continue to move forward after the movable baffle 20 is opened downward.

[0094] Optionally, the extending direction of the rotating slide groove 113 is consistent with the moving direction of the pool cleaning robot 200 from the opening 10b into the accommodating chamber 10a.

[0095] Specifically, the extension direction of the rotating groove 113 can be consistent with the forward direction of the pool cleaning robot 200 entering the accommodating chamber 10a from the opening 10b, so that the force in the forward direction loaded by the pool cleaning robot 200 to the towing mechanism 100 can efficiently drive the rotating shaft 23 of the movable baffle 20 to slide along the rotating groove 113, and the groove of the rotating groove 113 will not generate sliding resistance in other directions to the rotating shaft 23, thereby preventing the resistance force in the forward direction of the pool cleaning robot 200 entering the accommodating chamber 10a from acting on the towing body 10.

[0096] In other embodiments, the extension direction of the rotating slide 113 can also be a direction having a certain angle with the traveling direction of the pool cleaning robot 200 from the opening 10b into the accommodating chamber 10a. In this way, the movable baffle 20 has a sliding displacement in the traveling direction from the opening 10b to the accommodating chamber 10a during the sliding process along the rotating slide 113, thereby preventing the pool cleaning robot 200 from entering the accommodating chamber 10a from the opening 10b. The resisting force in the traveling direction of the pool cleaning robot 200 from the opening 10b acting on the towing body 10, and the movable baffle 20 and the towing body 10 cannot retreat, the pool cleaning robot 200 will not be able to move forward, that is, it will slip on the spot until the movable baffle 20 is pressed down to a certain angle before it can continue to move forward; or, it will cause abnormal movement of the towing mechanism 100, such as the towing mechanism 100 being pushed upward or pushed out of 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 pile.

[0097] Optional, see Figures 6a-8b The rotating slide groove 113 has a first end 113a and a second end 113b.

[0098] The first end 113a is close to the opening 10b, and the second end 113b is far away 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 far away from the front plate 12 than the second end 113b.

[0099] When the rotating shaft 23 is located at the first end 113 a , the movable baffle 20 closes the opening 10 b .

[0100] When the rotating shaft 23 is located at the second end 113 b , the movable baffle 20 opens the opening 10 b .

[0101] In this embodiment, when the movable baffle 20 rotates from a first state closing the opening 10b to a second state opening the opening 10b under the action of the pool cleaning robot 200, the baffle body 22 drives the rotating shaft 23 to move from the end of the rotating slide 113 close to the opening 10b toward the accommodating cavity 10a to the end away from the opening 10b.

[0102] For further optional information, see Figures 6a-8b The movable baffle 20 also includes an elastic reset member 26.

[0103] One end of the elastic return member 26 is connected to the rotating shaft 23 , and the other end of the elastic return member 26 is connected to the side plate.

[0104] The elastic deformation amount of the elastic return member 26 when the rotation shaft 23 is located at the first end 113 a is smaller than the elastic deformation amount of the elastic return member 26 when the rotation shaft 23 is located at the second end 113 b .

[0105] The elastic return member 26 is used to generate elastic deformation when the rotating shaft 23 moves from the first end 113a and rotates to the second end 113b, so that when the pool cleaning robot 200 no longer has an applied force on the movable baffle 20, or when the applied force of the pool cleaning robot 200 on the movable baffle 20 is less than the deformation recovery force of the elastic return member 26, the elastic return member 26 drives the rotating shaft 23 to move from the second end 113b and rotate back to the first end 113a under the deformation recovery force, that is, after the pool cleaning robot 200 enters the accommodating chamber 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 return member 26, so that the movable baffle 20 is blocked at the rear end of the pool cleaning robot 200 during the subsequent movement of the towing mechanism 100, thereby preventing the pool cleaning robot 200 from falling out of the accommodating chamber 10a.

[0106] For example, the elastic return member 26 includes, but is not limited to, an elastic structure. The elastic return member 26 includes, but is not limited to, an elastic metal member, an elastic rubber member, or a gas spring. The elastic metal member includes, but is not limited to, a spring, a spring, an elastic clip, or an elastic pull cord. The spring includes, but is not limited to, a tension spring or a compression spring.

[0107] In an optional implementation, see 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.

[0108] Specifically, the elastic stretching amount of the elastic reset member 26 when the rotating shaft 23 is located at the first end 113a is smaller than the elastic stretching amount of the elastic reset member 26 when the rotating shaft 23 is located at the second end 113b.

[0109] The elastic return member 26 is used to generate elastic tensile deformation when the rotating shaft 23 moves from the first end 113a and rotates to the second end 113b, so that when the pool cleaning robot 200 no longer has an applied force on the movable baffle 20, or when the applied force of the pool cleaning robot 200 on the movable baffle 20 is less than the tensile deformation recovery force of the elastic return member 26, the elastic return member 26 drives the rotating shaft 23 to move from the second end 113b and rotate back to the first end 113a under the tensile deformation recovery force, that is, after the pool cleaning robot 200 enters the accommodating chamber 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 return member 26, so that the movable baffle 20 is blocked at the rear end of the pool cleaning robot 200 during the subsequent movement of the towing mechanism 100, thereby preventing the pool cleaning robot 200 from falling out of the accommodating chamber 10a.

[0110] For further optional information, see Figure 7a and Figure 7b When the rotating shaft 23 is located at the first end 113a, the tension spring is in the first tension state, and the pulling force of the tension spring on the rotating shaft 23 keeps the movable baffle 20 in the first state.

[0111] See also Figure 8a and Figure 8b When the rotating shaft 23 is located at the second end 113b, the tension spring is in a second stretched state. The stretched length in the second stretched state is greater than the stretched length in the first stretched state, so that the elastic stretching amount of the elastic return member 26 when the rotating shaft 23 is located at the first end 113a is less than the elastic stretching amount of the elastic return member 26 when the rotating shaft 23 is located at the second end 113b.

[0112] Further optionally, the first end 113a of the tension spring is located closer to the first end 113a of the rotating slot 113 and further away 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 slot 113 is smaller than the distance between the first end 113a of the tension spring and the second end 113b of the rotating slot 113. The distance between the first end 113a of the tension spring and the bottom plate 14 is smaller than the distance between the second end 113b of the tension spring and the bottom plate 14.

[0113] Thus, in this embodiment, when the rotating shaft 23 is located at the first end 113a, the tension spring has a pulling force on the rotating shaft 23 away from the side of the bottom plate 14 and a pulling force on the second end 113b away from the rotating slide groove 113, so that the movable baffle 20 remains in the position of the first state.

[0114] Moreover, in the present embodiment, the rotating shaft 23 rotates from the first end 113a (the baffle body 22 is in the first state) toward the side where the bottom plate 14 is located (the baffle body 22 is in the second state), and the tension spring is stretched. The tension spring generates a rotational torque to restore the rotating shaft 23 to rotate, so that when the pool cleaning robot 200 no longer has an applied force on the movable baffle 20, or the applied force of the pool cleaning robot 200 on the movable baffle 20 is less than the tensile deformation recovery force of the tension spring, the tension spring drives the rotating shaft 23 to rotate and restore until the baffle body 22 is in the first state.

[0115] At the same time, in this embodiment, the rotating shaft 23 moves from the first end 113a toward the second end 113b, the tension spring is stretched, and the tension spring produces a tensile deformation that causes the rotating shaft 23 to move and recover, so that when the pool cleaning robot 200 no longer has an action force on the movable baffle 20, or the action force of the pool cleaning robot 200 on the movable baffle 20 is less than the tensile deformation recovery force of the tension spring, the tension spring drives the rotating shaft 23 to move and recover to the first end 113a.

[0116] For further optional information, see Figures 6a to 7b When the rotating shaft 23 is located at the first end 113a, the extension direction of the swing arm 21 is parallel to the extension 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 body 22 is the same or close to the center height of the running wheels of the pool cleaning robot 200, so that when the running wheels 250 of the pool cleaning robot 200 contact the outer wall of the baffle body 22, the center line position of the running wheels 250 of the pool cleaning robot 200 abuts against the center line position of the baffle body 22, thereby increasing the friction transmission efficiency between the running wheels 250 of the pool cleaning robot 200 and the outer wall of the baffle body 22, which is beneficial for the baffle body 22 to move toward the side where the bottom plate 14 is located as the running wheels 250 of the pool cleaning robot 200 rotate.

[0117] See also 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] See also Figure 7a-Figure 8bA connecting block 27 is provided at the end of the rotating shaft 23 away from the swing arm 21. The connecting block 27 extends in the same direction as the swing arm 21. One end of the connecting block 27 is integrally connected to a portion of the peripheral sidewall of the end of the rotating shaft 23 away from the swing arm 21. The other end of the connecting block 27 extends toward a 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 return member 26.

[0124] Furthermore, the extension length of the connecting block 27 is shorter than that of the rotating slot 113, allowing the connecting block 27 to be installed in the first side plate cavity 11c along the width direction from the opening 10b through the rotating slot 113. A U-shaped structure is formed between the connecting block 27, the rotating shaft 23, and the swing arm 21. A portion of this U-shaped structure passes through the rotating slot 113 and engages with the first sub-side plate 11a, allowing the rotating shaft 23 to be securely installed in the rotating slot 113.

[0125] Optional, see Figure 7a-Figure 8b A limiting member 114 is provided on the outer side of the rotating slide groove 113 for limiting the position of the movable baffle 20 in opening and closing the opening 10b, so that when the rotating shaft 23 is located at the first end 113a, the extension direction of the swing arm 21 is parallel to the extension direction of the side plate, and the movable baffle 20 is limited in the first state of closing the opening 10b; when the rotating shaft 23 is located at the second end 113b, the extension direction of the swing arm 21 is perpendicular to the extension direction of the side plate, and the movable baffle 20 is limited in the second state of opening the opening 10b.

[0126] For an optional embodiment of the first limiting member 114, please refer to Figure 7a-Figure 8b The limiting member 114 is disposed around a portion of the circumference of the rotating chute 113. A notch 115 is formed outside the rotating chute 113 where the limiting member 114 is not disposed. The rotating shaft 23 can rotate within the area defined by the notch 115.

[0127] Specifically, the limiting member 114 is protruded from the cavity wall of the first side plate cavity 11c of the first sub-side plate 11a. The limiting member 114 is roughly an arc-shaped plate. The arc-shaped plate is arranged around a portion of the circumference of the rotating chute 113. The limiting member 114 does not surround the outer side of the rotating chute 113 to form a gap 115 connected to the rotating chute 113, and the connecting block 27 of the rotating shaft 23 can rotate within the area defined by the gap 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 extension direction of the swing arm 21 is parallel to the extension direction of the side plate, and the movable baffle 20 is in the first state of closing the opening 10b.

[0128] 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 extension direction of the swing arm 21 is perpendicular to the extension direction of the side plate, and the movable baffle 20 is in the second state of opening the opening 10b.

[0129] For an optional implementation of the second limiting member 114, please refer to Figure 4 and Figure 5 The first side plate 11 has a rotation groove 11d near the opening 10b. The swing arm 21 rotates within the rotation groove 11d. The rotation groove 11d has a first groove sidewall 111 and a second groove sidewall 112 that intersect each other. The stopper 114 includes the first groove sidewall 111 and the second groove sidewall 112.

[0130] See also 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 extension direction of the swing arm 21 is parallel to the extension direction of the side plate, and the movable baffle 20 is in the first state of closing the opening 10b.

[0131] See also 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 extension direction of the swing arm 21 is perpendicular to the extension direction of the side plate, and the movable baffle 20 is in the second state of opening the opening 10b.

[0132] Further optionally, the first groove sidewall 111 faces the side where the bottom plate 14 is located. Further, the plane where the first groove sidewall 111 is located is parallel or nearly parallel to the plane where the bottom plate 14 is located.

[0133] Further optionally, the second groove sidewall 112 faces away from the side where the front plate 12 is located. Furthermore, the plane where the second groove sidewall 112 is located is perpendicular or nearly perpendicular to the plane where the bottom plate 14 is located.

[0134] The first groove sidewall 111 is located on the side of the second groove sidewall 112 facing away from the front plate 12. The second groove sidewall 112 is connected to the end surface 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 connected to the bottom plate 14, so that the opening 10b is fully opened.

[0135] Furthermore, the thickness of the swing arm 21 is less than the depth of the rotation groove 11d, that is, the swing arm 21 is always located in the rotation groove 11d during the rotation process, so as to avoid the swing arm 21 protruding from the rotation groove 11d and causing movement interference to the pool cleaning robot 200 entering and exiting the accommodating chamber 10a.

[0136] For an optional embodiment of the second movable baffle 20, please 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.

[0137] The rotating shaft 23 is provided on the side plate and is rotatably connected to the side plate. The rotating shaft 23 is provided along the width direction, and the extending direction of the swing arm 21 is perpendicular to the extending direction of the rotating shaft 23.

[0138] This embodiment differs from the first optional embodiment of the movable baffle 20 in that the rotation slot 11d on the side plate for the rotation shaft 23 to pass through can be a circular hole. The rotation shaft 23 rotates relative to the side plate but does not move relative to the side plate toward the accommodating cavity 10a.

[0139] The difference between this embodiment and the first optional embodiment of the movable baffle 20 is that, please refer to Figure 10 and Figure 11 The swing arm 21 includes a fixed arm 214 and a telescopic arm 212 that can be extended and retracted 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.

[0140] Furthermore, the fixed arm 214 and the telescopic arm 212 have a certain telescopic space in the connection direction thereof.

[0141] For further optional information, see Figure 10 and Figure 11 The swing arm 21 further includes a retractable elastic member 213 elastically connected between the fixed arm 214 and the retractable arm 212. The retractable elastic member 213 includes, but is not limited to, an elastic metal member, an elastic rubber member, or a gas spring. Elastic metal members include, but are not limited to, springs, spring sheets, elastic clips, or elastic pull cords. Springs include, but are not limited to, tension springs or compression springs.

[0142] See also 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 extension direction of the swing arm 21 is parallel to the extension direction of the side plate, and the movable baffle 20 is in the first state of closing the opening 10b.

[0143] See also 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 extension direction of the swing arm 21 is perpendicular to the extension direction of the side plate, and the movable baffle 20 is in the second state of opening the opening 10b.

[0144] During the rotation process, the baffle body 22 can move toward the accommodating chamber 10a under the action of the pool cleaning robot 200. That is, the baffle body 22 can rotate and move synchronously toward the accommodating chamber 10a (the side where the front plate 12 is located). This allows the pool cleaning robot 200 to contact the baffle body 22 while exerting a resisting force on the baffle body 22 in the forward direction. The baffle body 22 can move toward the accommodating chamber 10a (the side where the front plate 12 is located) under the action of the resisting force in the forward direction, thereby preventing the towing body 10 from being lifted upward or pushed out of the direction of the pool wall M1, or preventing the pool cleaning robot 200 from slipping or not moving in place, and can only continue to move forward after the movable baffle 20 is opened downward. In addition, since the pool cleaning robot 200 contacts the baffle body 22, it also has a downward (towards the pool wall M1) rotational force on the baffle body 22. The baffle body 22 moves toward the accommodating chamber 10a (the side where the front plate 12 is located) and rotates toward the pool wall M1 side. The baffle body 22 no longer forms an obstacle to the forward direction of the pool cleaning robot 200, that is, the towing mechanism 100 is no longer subjected to the resisting 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 accommodating chamber 10a through the opening 10b.

[0145] Second, see Figure 1 and Figure 2 The present embodiment provides a pool cleaning system 2000. The pool cleaning system 2000 includes a pool cleaning robot 200 and the water-discharging base station 1000 described in any of the aforementioned embodiments. The pool cleaning robot 200 is located within the accommodating cavity 10a of the towing mechanism 100. The water-discharging base station 1000 is used to tow the pool cleaning robot 200 ashore or to transport the pool cleaning robot 200 into the pool.

[0146] The following provides specific examples of the structure of the pool cleaning robot 200 , how the pool cleaning robot 200 opens the movable baffle 20 by itself, enters the accommodating chamber 10 a (returns to the pile), and how the movable baffle 20 closes the opening 10 b .

[0147] For further optional information, see Figure 12 The pool cleaning robot 200 includes running wheels 250. The running wheels 250 include a track 210 and a first track wheel 220 and a second track wheel 230 disposed within the track 210. The first track wheel 220 and the second track wheel 230 rotate to drive the track 210 to rotate clockwise or counterclockwise, causing the pool cleaning robot 200 to move forward or backward.

[0148] The pool cleaning robot 200 further includes a track drive assembly (not shown) for driving the first track wheel 220 and the second track wheel 230 to rotate, thereby driving the track 210 to rotate clockwise or counterclockwise, so that the pool cleaning robot 200 moves forward or backward.

[0149] Furthermore, the pool cleaning robot 200 includes a water pump (not shown). When in operation, the water pump sprays water toward the pool cleaning robot 200, generating a pressing force from the top against the bottom of the pool cleaning robot 200, forcing the bottom of the pool cleaning robot 200 into close contact with the pool wall M1 or the pool bottom. Under the traction of the running wheels 250, the pool cleaning robot 200 moves forward, keeping its bottom in close contact with the pool wall M1 or the pool bottom.

[0150] When the pool cleaning robot 200 climbs the pool wall M1 and enters the accommodating chamber 10a, the track drive assembly is used to drive the track 210 to rotate about a first rotation direction. The first rotation direction is such that the front track 210 continuously moves toward the pool wall M1, and the rear track 210 continuously moves from the pool wall M1 toward the top of the pool cleaning robot 200.

[0151] The water pump is in working state, so that the bottom of the pool cleaning robot 200 is closely attached to the pool wall M1.

[0152] Pool cleaning robot 200 climbs pool wall M1 until tracks 210 at the front end of robot 200 contact the outer wall of movable baffle 20 (baffle body 22). Tracks 210 drive movable baffle 20 toward base plate 14 via friction or engagement, causing movable baffle 20 to move from the first state to the second state.

[0153] During this process, since the movable baffle 20 can move toward the accommodating chamber 10a under the action of the pool cleaning robot 200 during the rotation process, the track 210 of the pool cleaning robot 200 contacts the movable baffle 20 and has a resisting force in the forward direction and a rotational torque toward the bottom plate 14 side on the movable baffle 20. The movable baffle 20 can move toward the accommodating chamber 10a (the side where the front plate 12 is located) under the action of the resisting force in the forward direction, thereby preventing the towing body 10 from being lifted upward or pushed out of the direction of the pool wall M1, or preventing the pool cleaning robot 200 from slipping or staying still, and can only continue to move forward after the movable baffle 20 opens downward; the movable baffle 20 rotates under the rotational torque toward the bottom plate 14 side, and the movable baffle 20 moves from the first state to the second state.

[0154] The water pump is in operation, and the pressure exerted 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 exerted by the water pump on the movable baffle 20 is greater than the restoring force of the elastic return member 26. Therefore, the movable baffle 20 is in a fully depressed state (the second state). As the pool cleaning robot 200 climbs the wall, water ejected from the water pump nozzle exerts pressure on the wall. This pressure ensures that the pool cleaning robot 200 consistently overcomes the restoring force of the elastic return member 26, depressing the movable baffle 20 and using the baffle body 22 of the movable baffle 20 as a transition until the pool cleaning robot 200 fully enters the towing mechanism 100.

[0155] Optional, see Figure 12 The outer surface of the crawler 210 is provided with a plurality of first protrusions 211. The first protrusions 211 include but are not limited to protrusions, or protrusions. In this embodiment, the first protrusions 211 are protrusions. The first protrusions 211 extend along the width direction X.

[0156] See also Figure 12 The movable baffle 20 is provided with a plurality of second protrusions 24 on the surface facing away from the accommodating cavity 10a. The second protrusions 24 include, but are not limited to, protrusions or protrusions. In this embodiment, the second protrusions 24 are protrusions. The second protrusions 24 extend along the width direction X.

[0157] When the track 210 contacts the surface (outer wall) of the movable baffle 20 facing away from the accommodating chamber 10a and the track 210 advances into the accommodating chamber 10a, at least a portion of the first protrusion 211 engages with at least a portion of the second protrusion 24, thereby increasing friction between the track 210 and the movable baffle 20. This facilitates the track 210 in driving the movable baffle 20 to rotate, thereby enabling the pool cleaning robot 200 to open the opening 10b on its own. The movable baffle 20 moves from the first state to the second state under the action of the track 210.

[0158] See also Figure 13-15 When the pool cleaning robot 200 enters the accommodating chamber 10a and reaches the set limit or moves to a certain position, the rear end of the track 210 of the pool cleaning robot 200 no longer contacts the movable baffle 20. That is, when the pool cleaning robot 200 is located in the accommodating chamber 10a, the rear end of the track 210 separates from the baffle body 22 of the movable baffle 20. The movable baffle 20 is no longer subjected to the downward pressure of the pool cleaning robot 200. The movable baffle 20 rotates to the first state under the restoring force of the elastic return 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.

[0159] Optionally, while the towing mechanism 100 is being lifted, the tracks 210 are stopped, and the water pump stops operating. As the pool cleaning robot 200 gradually leaves the water, it descends slightly under the action of gravity, and the rear end of the tracks 210 contacts the baffle body 22. The baffle body 22 is used to support the rear end of the pool cleaning robot 200, preventing the pool cleaning robot 200 from leaving the towing mechanism 100 until the pool cleaning robot 200 is completely on land.

[0160] Furthermore, the center line of the track 210 of the pool cleaning robot 200 is aligned with the center line of the baffle body 22, so that the support force of the baffle body 22 on the rear end of the pool cleaning robot 200 is aligned with the pool cleaning robot 200, thereby preventing the pool cleaning robot 200 from tilting and falling in the accommodating chamber 10a.

[0161] Since the force exerted by the pool cleaning robot 200 on the baffle body 22 during the landing process approximately passes through the axis of the baffle body 22, and the track 210 does not rotate, the baffle body 22 will not rotate to cause the pool cleaning robot 200 to be unlocked.

[0162] Optional, see Figure 16 and Figure 17 When the pool cleaning robot 200 is in the accommodating chamber 10a, the movable baffle 20 is spaced apart from the pool cleaning robot 200 during the rotation process from the second state to the first state, so as to avoid position interference between the movable baffle 20 and the pool cleaning robot 200 during the rotation process, resulting in the movable baffle 20 being unable to rotate to the first state or the second state.

[0163] Optionally, the motion 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.

[0164] For further optional information, see Figure 16 and Figure 17 The movable baffle 20 rotates from the first state to the second state by rotating around the quarter-circle track 210 of the pool cleaning robot 200. Furthermore, optionally, the gap formed between the movable baffle 20 and the quarter-circle track 210 of the pool cleaning robot 200 during the rotation from the second state to the first state is a non-uniform gap. For example, during the rotation 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 track 210 gradually increases.

[0165] For further optional information, see Figure 16 and Figure 17When the pool cleaning robot 200 is in the accommodating chamber 10a, the rotation axis (hereinafter referred to as the first rotation axis) of the rotating shaft 23 of the movable baffle 20 when it is located at the second end 113b of the rotating slide groove 113 is concentrically arranged with the axis of the walking wheel 250 of the pool cleaning robot 200 (such as the aforementioned second crawler wheel 230).

[0166] Specifically, the first rotation axis of the movable baffle 20 is the center line of the rotation axis of the swing arm 21. From the cross section along the height direction Z and the length direction Y, the first rotation axis of the movable baffle 20 is the center position of the rotation axis of the swing arm 21.

[0167] From the cross-section along the height direction Z and the length direction Y, the axis of the running wheel 250 (such as the aforementioned second track wheel 230) of the pool cleaning robot 200 is located at the center of the running wheel 250 (such as the aforementioned second track wheel 230) of the pool cleaning robot 200.

[0168] In this embodiment, when the pool cleaning robot 200 is in the accommodating chamber 10a, the first rotation axis of the movable baffle 20 is concentrically arranged with the axis of the walking wheel 250 of the pool cleaning robot 200 (for example, the aforementioned second track wheel 230). In this way, when the pool cleaning robot 200 is in the accommodating chamber 10a, the gap between the inner surface of the movable baffle 20 and the outer surface of the track 210 in the first state is relatively small. In this way, the retreat space of the pool cleaning robot 200 when it retreats to abut the inner surface of the movable baffle 20 is small, thereby avoiding a large distance between the pool cleaning robot 200 and the front end limit portion 51 when it retreats to abut the inner surface of the movable baffle 20, thereby causing the front end limit portion 51 to be unable to limit the front end of the pool cleaning robot 200, causing the pool cleaning robot 200 to fall off from the accommodating chamber 10a and overturn.

[0169] Moreover, the gap between the inner surface of the movable baffle 20 and the outer surface of the track 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 accommodating chamber 10a. In addition, it is also beneficial for the pool cleaning robot 200 to completely enter the accommodating chamber 10a. After the movable baffle 20 is in the second state, it will not be subjected to the downward pressure of the walking wheel 250, which is conducive to the movable baffle 20 returning to the first state under the drive of the elastic reset member 26.

[0170] Further, see Figure 17 and Figure 18The short rotation 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 arc track 210 to ensure that the movable baffle 20 does 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 made relatively small, and thus the height and length dimensions of the towing mechanism 100 are also made 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, resulting in a large space for the pool cleaning robot 200 to slide down in the accommodating chamber 10a, the front end of the pool cleaning robot 200 is easily separated from the front end limit portion 51 (detailed description later), and then the pool cleaning robot 200 falls off and flips over in the accommodating chamber 10a; in this embodiment, by setting the gap between the tail end of the pool cleaning robot 200 and the movable baffle 20 to be smaller, even if the space for the pool cleaning robot 200 to slide down in the accommodating chamber 10a is small, it is not easy for the pool cleaning robot 200 to fall off and flip over in the accommodating chamber 10a.

[0171] Further, see Figure 17 and Figure 18 The outer surface of the crawler 210 is provided with a first protrusion 211, and the inner surface 201 of the movable baffle 20 is provided with a third protrusion 25. The difference between the aforementioned short rotation radius R2 of the movable baffle 20 and the radius R1 corresponding to the 1 / 4 arc crawler 210 is the distance between the end of the first protrusion 211 and the end of the third protrusion 25. The distance between the end of the first protrusion 211 and the end of the third protrusion 25 is H2.

[0172] Of course, in other embodiments, the first rotational axis of the movable baffle 20 is not concentric with the axis of the running wheel 250 (e.g., the aforementioned second track wheel 230) of the pool cleaning robot 200. For example, the first rotational axis of the movable baffle 20 and the axis of the running wheel 250 (e.g., the aforementioned second track wheel 230) of the pool cleaning robot 200 are collinear in the longitudinal direction Y. Optionally, when the movable baffle 20 is in the first state, the line connecting the center of the baffle body 22 and the axis of the rotation of the running wheel 250 is parallel to the base plate 14. In this way, when the towing mechanism 100 is in contact with the pool wall M1, the pool cleaning robot 200 is in a vertical position and the tail end of the track 210 of the pool cleaning robot 200 abuts against the baffle body 22, thereby reducing eccentricity and thereby reducing problems such as instability and falling off of the pool cleaning robot 200.

[0173] For another example, the first rotation axis of the movable baffle 20 is collinearly arranged with the axis of the running wheel 250 (e.g., the aforementioned second track wheel 230) of the pool cleaning robot 200 in the height direction Z. Of course, the proximity of the first rotation axis of the movable baffle 20 and the axis of the running wheel 250 (e.g., the aforementioned second track wheel 230) of the pool cleaning robot 200 ensures that the distance between the movable baffle 20 and the quarter-circle track 210 is close during rotation, thereby reducing the risk of the movable baffle 20 falling off and tipping over in the accommodating cavity 10a and reducing the size of the towing body 10.

[0174] See also Figure 16 The outer surface 202 of the movable baffle 20 (see Figure 17 ) is smaller than the distance H1 between the first rotation axis of the movable baffle 20 and the back surface of the towed body 10 (the pool wall M1), thereby preventing the movable baffle 20 from colliding with the pool wall M1 when rotating to the second state. The back surface of the towed body 10 is disposed opposite to the bottom wall of the accommodating chamber 10a.

[0175] The inner surface 201 of the movable baffle 20 (see Figure 17 ) has a short rotation radius R2 greater than the radius R1 of the outer contour circle of the running wheel 250 (e.g., the aforementioned second track wheel 230) of the pool cleaning robot 200. The outer contour circle of the running wheel 250 (e.g., the aforementioned second track wheel 230) of the pool cleaning robot 200 refers to a circle having a radius, the distance between the farthest point on the corresponding quarter-circle track 210 and the center of the circle, and the projection center of the running wheel 250 (e.g., the aforementioned second track wheel 230) along the width direction X as the center of the circle.

[0176] From another perspective, see Figure 19 When the movable baffle 20 is in the second state, the maximum distance H3 between the inner surface 201 and the outer surface of the movable baffle 20 (the distance between the end point of the second protrusion 24 and the end point of the third protrusion 25 in the height direction Z) is smaller than the minimum distance H4 between the outer surface of the crawler 210 (the end point of the first protrusion 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 motion interference between the movable baffle 20 and the pool wall M1 and the outer surface of the crawler 210 when it rotates to the second state.

[0177] See also Figure 19When the movable baffle 20 rotates to the second state, it is located below the straight portion of the crawler track 210. A gap exists between the inner surface 201 of the movable baffle 20 and the bottom surface of the running wheel 250 of the pool cleaning robot 200 (such as the second crawler wheel 230 described above). The movable baffle 20 will not be pressed by the straight portion of the crawler track 210, resulting in the elastic return member 26 being unable to return to the first state.

[0178] 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 accommodating chamber 10a), since the movable baffle 20 is located below the straight portion of the track 210 when it rotates to the second state, it will be pressed by the straight portion of the track 210, resulting in the movable baffle 20 being unable to return to the first state under the action of the elastic return member 26. If the movable baffle 20 wants to be smoothly reset from the second state under the action of the elastic reset member 26, it is necessary to move the movable baffle 20 in the second state to below the curved surface corresponding to the crawler 210. In this way, even if the movable baffle 20 is reset to the first state, the distance between the baffle body 22 and the crawler 210 will be larger, which on the one hand increases the length of the entire towing body 10 and on the other hand results in a large space for the pool cleaning robot 200 to slide down in the accommodating chamber 10a, causing the front end of the pool cleaning robot 200 to easily separate from the front end limit portion 51 (detailed description later), and then the pool cleaning robot 200 falls off and flips over in the accommodating chamber 10a; in this embodiment, by setting the gap between the tail end of the pool cleaning robot 200 and the movable baffle 20 to be smaller, even if the space for the pool cleaning robot 200 to slide down in the accommodating chamber 10a is small, it is not easy for the pool cleaning robot 200 to fall off and flip over in the accommodating chamber 10a.

[0179] Alternatively, see Figure 12 The outer contour of the baffle body 22 is curved. Optionally, the outer sidewall of the baffle body 22 is curved. For example, when the pool cleaning robot 200 contacts the outer sidewall of the baffle body 22 in the first state outside the accommodating chamber 10a, the track 210 of the pool cleaning robot 200 first contacts the bottom end of the outer sidewall of the baffle body 22 (the third protrusion 25). As the pool cleaning robot 200 moves forward, the pool cleaning robot 200 presses the baffle body 22 downward (rotates it downward by a certain angle), and the outer sidewall of the baffle body 22 also becomes curved, allowing the pool cleaning robot 200 to gradually contact the top end of the outer sidewall of the baffle body 22 (the third protrusion 25) after the baffle body 22 rotates downward by a certain angle.

[0180] Optional, see 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 body 10 and is arranged 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. Furthermore, the front end limiting portion 51 cooperates with the movable baffle 20 to limit the pool cleaning robot 200 in the traveling direction (front and back direction) and the height direction Z, so that the pool cleaning robot 200 can be stably restrained in the accommodating cavity 10a.

[0181] Specifically, the orthographic projection of the front end stopper 51 onto the surface of the base plate 14 is at least partially located on the base plate 14, so that at least a portion of the front end stopper 51 protrudes from the front plate 12. Furthermore, a concave space is formed between the front end stopper 51, the front plate 12, and the base plate 14 to accommodate the front end of the pool cleaning robot 200. At least a portion of the front end stopper 51 is located at the top side of the front end of the pool cleaning robot 200. The front end stopper 51 cooperates with the base plate 14 to limit the position of the pool cleaning robot 200 in the height direction Z. The height direction Z is perpendicular to the base plate 14.

[0182] Further, see Figure 13 When the front end of the pool cleaning robot 200 abuts the front end limiter 51 and the movable baffle 20 is in the first state, the movable baffle 20 cooperates with the front end limiter 51 to limit the front-to-back direction of the pool cleaning robot 200. The front-to-back direction in this application may also refer to the longitudinal direction Y, that is, the direction perpendicular to the front plate 12.

[0183] Further optionally, the front end limit portion 51 can roll relative to the towing body 10 so as to reduce the friction between the track 210 (or the running wheel 250) and the front end limit portion 51 when the front end limit portion 51 is in contact with the track 210 (or the running wheel 250) and the track 210 (or the running wheel 250) is in a rotating state.

[0184] Optional, see Figure 13-15The front end limiting portion 51 is a roller member. The distance between the rolling axis of the front end limiting portion 51 and the bottom wall of the accommodating chamber 10a (the bottom plate 14) is greater than the distance between the rotation axis 23 of the running wheel 250 and the bottom wall of the accommodating chamber 10a (the bottom plate 14) when the pool cleaning robot 200 is located in the accommodating chamber 10a. In this way, the front end limiting portion 51 abuts against the top of the front end of the running wheel 250, thereby limiting the pool cleaning robot 200 in the height direction Z between the front end limiting portion 51 and the bottom plate 14. The front end limiting portion 51 and the movable baffle 20 in the first state limit the pool cleaning robot 200 in the length direction Y.

[0185] Optionally, the front end limiting portion 51 is a roller.

[0186] Optional, see Figure 4 The bottom plate 14 is provided with a plurality of raised portions 141. The raised portions 141 are arranged along the direction (width direction X) in which the first side plate 11 and the front plate 12 are opposite each other. The raised portions 141 are configured to engage with the tracks 210 of the pool cleaning robot 200 when the pool cleaning robot 200 is within the accommodating chamber 10a.

[0187] Specifically, the bottom plate 14 may be provided with two groups of raised portions 141, which are spaced apart in the width direction X. Each group of raised portions 141 includes a plurality of raised portions 141. The plurality of raised portions 141 are arranged in sequence along the length direction Y. The raised portions 141 are convex strips extending along the width direction X.

[0188] Each set of protrusions 141 cooperates with a track 210 to increase the friction between the pool cleaning robot 200 and the base plate 14 .

[0189] Optional, see Figure 12 The bottom plate 14 is provided with a roller brush groove 142 in an area near the front plate 12. The roller brush groove 142 is used to accommodate the cleaning roller brush of the pool cleaning robot 200 when the pool cleaning robot 200 is in the accommodating chamber 10a, so as to prevent the cleaning roller brush of the pool cleaning robot 200 from being squeezed by the bottom plate 14 and deformed.

[0190] 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.

[0191] 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.

[0192] 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.

[0193] 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.

[0194] 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.

[0195] 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 this field can change, modify, replace and modify the above embodiments within the scope of the present application, and these improvements and modifications are also considered to be within the scope of protection of the present application.
