Description

Off-water base station and cleaning system

[0001] This application claims priority to Chinese Patent Application No. 2025101211012, filed on January 24, 2025, entitled “Water-free base station and cleaning system”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of cleaning equipment technology, specifically to a water-off base station and cleaning system. Background Technology

[0003] With the improvement of people's living standards, the use of private swimming pools is becoming increasingly popular. Pool cleaning robots, as convenient automated devices, are widely used in pool cleaning and maintenance. After the cleaning task is completed, the pool robot remains submerged in water, requiring users to manually remove it. This retrieval process is somewhat dangerous, and prolonged immersion reduces the robot's lifespan. Therefore, there is an urgent need to provide an off-water base station to assist the robot in automatically retrieving itself from the water.

[0004] To address the aforementioned technical problems, US12084884B2 discloses a device for removing or placing a pool cleaner from water. This device includes a support frame, a movable plate, a motor, and a cable reel. The operation is as follows: the support frame is fixed to the edge of the pool; the motor drives the movable plate from a retracted position (horizontally above the frame) to an extended position (outer edge submerged 10-20 cm underwater); then, the pool cleaner is moved onto the movable plate via cable traction from the cable reel or by the pool cleaner's autonomous movement; finally, the motor drives the movable plate back to the retracted position. However, in this solution, the pool cleaner relies solely on cable traction and surface guidance from the movable plate to transfer to the support frame. This results in low alignment accuracy, an inability to actively correct the pool cleaner's direction of travel, and low fault tolerance, making the device inefficient at removing or placing the pool cleaner from the water. Summary of the Invention

[0005] In view of this, this application provides a water-off base station and a cleaning system. The water-off base station can assist the cleaning robot in getting out of the pool and into the water, eliminating the need for the user to manually retrieve the cleaning robot from the pool, thus avoiding danger to the user during the retrieval process. It can also prevent the cleaning robot from being soaked for a long time, extending the service life of the cleaning robot.

[0006] This application provides a water-removing base station, comprising: a base station body and a towing mechanism, wherein the towing mechanism is movably connected to the base station body; the towing mechanism includes a main body, a movable baffle, and a rotating shaft, wherein the main body is movably connected to the base station body, the main body having a receiving cavity for accommodating a cleaning robot and an opening communicating with the receiving cavity, the movable baffle being located at the opening of the main body, and the movable baffle being rotatably connected to the inner sidewall of the main body via the rotating shaft to open or close the opening; wherein, during the process of opening the opening, the orthographic projection distance between the center of the movable baffle and the center of the rotating shaft on the bottom wall of the main body gradually decreases in the direction from the opening towards the interior of the receiving cavity.

[0007] Furthermore, when the movable baffle closes the opening, the orthographic distance between the center of the movable baffle and the center of the rotating shaft on the bottom wall of the main body is equal to the straight-line distance between the center of the movable baffle and the center of the rotating shaft in the direction from the opening towards the interior of the receiving cavity.

[0008] Furthermore, when the movable baffle closes the opening, in the direction from the opening towards the interior of the receiving cavity, the orthographic projection distance between the center of the movable baffle and the center of the rotating shaft on the bottom wall of the main body is less than the straight-line distance between the center of the movable baffle and the center of the rotating shaft, and along the first direction, the center of the movable baffle is closer to the bottom wall of the receiving cavity than the center of the rotating shaft.

[0009] Furthermore, when the movable baffle opens the opening, the orthographic distance between the center of the movable baffle and the center of the rotating shaft on the bottom wall of the main body is less than the straight-line distance between the center of the movable baffle and the center of the rotating shaft in the direction from the opening towards the interior of the receiving cavity.

[0010] Furthermore, the towing mechanism also includes a limiting member, which is connected to the main body and located on the side of the receiving cavity near the opening, and is used to limit the movable baffle.

[0011] Furthermore, the rotating shaft includes a first sub-shaft and a second sub-shaft, which are respectively disposed on opposite sides of the main body; the movable baffle includes a first rotating part, a blocking part, and a second rotating part connected together. The first rotating part is rotatably connected to the main body through the first sub-shaft, and the second rotating part is rotatably connected to the main body through the second sub-shaft. The first rotating part and the second rotating part cooperate to realize the rotation of the blocking part relative to the main body, thereby opening or closing the opening.

[0012] Furthermore, the towing mechanism also includes a protective plate connected to the main body, the protective plate and the main body forming a protective cavity, the protective cavity being used to house at least one of the first rotating part and the second rotating part.

[0013] Furthermore, the blocking part has a first protrusion on the side away from the receiving cavity, the first protrusion being used to engage with the track wheel of the cleaning robot to open the movable baffle relative to the opening; the blocking part has a second protrusion on the side facing the receiving cavity, the second protrusion being used to engage with the track wheel of the cleaning robot to open or close the movable baffle relative to the opening.

[0014] Furthermore, the towing mechanism also includes a reset mechanism, which is connected to the rotating shaft, the movable baffle, and the towing mechanism respectively. The reset mechanism is used to switch the movable baffle from being open relative to the opening to being closed relative to the opening.

[0015] Furthermore, the reset mechanism is a torsion spring, which includes a sleeve portion, a first torsion arm, and a second torsion arm. The first torsion arm and the second torsion arm are respectively connected to opposite sides of the sleeve portion. The sleeve portion is sleeved on the outer periphery of the rotating shaft. The first torsion arm abuts against the movable baffle, and the second torsion arm abuts against the main body portion.

[0016] Furthermore, the reset mechanism includes a positioning cylinder, a linkage, a transmission assembly, and a rotating wheel. The positioning cylinder is rotatably installed in the receiving cavity and disposed away from the opening. The transmission assembly includes a first transmission member, a second transmission member, and a friction belt. The linkage passes through the positioning cylinder and the first transmission member. In the direction from the opening toward the inside of the receiving cavity, the second transmission member and the first transmission member are spaced apart. The friction belt is sleeved on at least a portion of the outer periphery of the first transmission member and at least a portion of the outer periphery of the second transmission member. The second transmission member engages with the rotating wheel, and the rotating wheel is connected to the movable baffle.

[0017] Furthermore, the towing structure also includes a first guide portion and a second guide portion, both of which are connected to the main body portion. The first guide portion and the second guide portion are located on opposite sides of the opening. The distance between the first guide portion and the second guide portion gradually decreases from the opening toward the interior of the receiving cavity.

[0018] Furthermore, the towing mechanism also includes a plurality of third protrusions, which are spaced apart on the bottom wall of the receiving cavity.

[0019] This application provides a cleaning system, which includes a cleaning robot and a water-off base station provided in this application. The water-off base station is used to assist the cleaning robot in getting out of the pool and in entering the pool.

[0020] Furthermore, the cleaning robot includes a cleaning body and tracked wheels. The tracked wheels are rotatably connected to the cleaning body and are used to drive the cleaning body to move. When the cleaning robot enters the receiving cavity, the rotation direction of the tracked wheels is a first rotation direction. When the cleaning robot exits the receiving cavity, the rotation direction of the tracked wheels is a second rotation direction, and the first rotation direction is opposite to the second rotation direction.

[0021] Furthermore, during the process of the cleaning robot entering the receiving cavity, the end of the track wheel near the movable baffle is the first end, and the first end contacts the movable baffle.

[0022] Furthermore, during the process of the cleaning robot entering the receiving cavity, the end of the movable baffle near the bottom wall of the receiving cavity is the second end, and the vertical distance from the first end to the bottom wall of the receiving cavity is greater than or equal to the vertical distance from the second end to the bottom wall of the receiving cavity.

[0023] In this application, when the water-removing base station is used to assist the cleaning robot in getting out of the pool, the towing mechanism is initially in a first position, the cleaning robot enters the towing mechanism from the pool, and the towing mechanism moves relative to the base station body to a second position, thereby enabling the cleaning robot to leave the pool and get out. When the water-removing base station is used to assist the cleaning robot in entering the pool, the towing mechanism is initially in a second position, and the towing mechanism moves relative to the base station body to a first position, allowing the cleaning robot to detach from the towing mechanism and enter the pool to perform its work. The water-removing base station provided in this application, used to assist the cleaning robot in getting out of the pool and entering the pool, eliminates the need for users to manually retrieve the cleaning robot from the pool, avoiding potential dangers during retrieval and improving the user experience. Furthermore, it prevents the cleaning robot from being submerged for extended periods, extending its lifespan. Moreover, the water-removing base station also enables the cleaning robot to automatically enter the water without manual operation, further improving the robot's performance.

[0024] In this application, the main body is movably connected to the base station body. When the cleaning robot is housed in the receiving cavity, the main body can move the cleaning robot between a first position and a second position to bring the cleaning robot out of or into the pool. In this application, the movable baffle is rotatably connected to the main body via the rotating shaft to open or close the opening. When the movable baffle is open relative to the opening, the cleaning robot can enter and exit the receiving cavity, improving the efficiency of the cleaning robot's entry and exit. When the movable baffle is closed relative to the opening, the movable baffle can prevent the cleaning robot from detaching from the receiving cavity, thereby improving the structural stability of the cleaning robot mounted on the main body.

[0025] In this application, during the switching process of the movable baffle closing relative to the opening and opening relative to the opening, the distance between the orthographic projection of the center of the movable baffle and the center of the rotating shaft on the bottom wall of the main body gradually decreases in the direction from the opening towards the interior of the receiving cavity. In other words, the distance between the orthographic projection of the center of the movable baffle along the first direction and the orthographic projection of the center of the rotating shaft along the first direction in the second direction gradually decreases. This allows the center of the movable baffle to move towards the side away from the cleaning robot during its movement into the receiving cavity, thus avoiding the movable baffle from obstructing the movement of the cleaning robot during its rotation relative to the main body. This ensures the efficiency of the cleaning robot entering the receiving cavity and improves the efficiency of the water-removing base station in assisting the cleaning robot to go ashore. During the switching process of the movable baffle closing relative to the opening and opening relative to the opening, if the distance between the orthographic projection of the center of the movable baffle along the first direction and the orthographic projection of the center of the rotating shaft along the first direction in the second direction increases, it indicates that during the movement of the cleaning robot into the receiving cavity, the center of the movable baffle moves towards the side closer to the cleaning robot. In this case, the movable baffle will exert a reaction force on the cleaning robot in the opposite direction of movement to hinder the forward movement of the cleaning robot, thereby affecting the efficiency of the cleaning robot entering the receiving cavity.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0055] In this document, references to "embodiment" or "implementation" mean that a particular feature, structure, or characteristic described in connection with an embodiment or implementation may be included in at least one embodiment of this application.

[0056] With the improvement of people's living standards, the use of private swimming pools is becoming increasingly popular. Pool cleaning robots, as convenient automated devices, are widely used in pool cleaning and maintenance. After the cleaning task is completed, the pool robot remains submerged in water, requiring users to manually remove it. This retrieval process is somewhat dangerous, and prolonged immersion reduces the robot's lifespan. Therefore, there is an urgent need to provide an off-water base station to assist the robot in automatically retrieving itself from the water.

[0057] In common water-free base stations, if the tracks of a cleaning robot are used to open the baffle of the receiving cavity so that the cleaning robot can enter the receiving cavity, the baffle may exert a reaction force on the cleaning robot in the opposite direction of travel as it rotates under the drive of the tracks, thus hindering the cleaning robot's progress and affecting the efficiency of the cleaning robot entering the receiving cavity.

[0058] Please refer to Figures 1 to 4. This application provides a water-off base station 100, which includes a base station body 110 and a towing mechanism 120, wherein the towing mechanism 120 is movably connected to the base station body 110.

[0059] Understandably, the water-off base station 100 is used to assist the cleaning robot 310 in getting out of the pool, and the water-off base station 100 is also used to assist the cleaning robot 310 in entering the pool.

[0060] Understandably, the base station body 110 is located in the edge area of ​​the pool, that is, on the shore of the pool.

[0061] Understandably, the towing mechanism 120 is movably connected to the base station body 110. The towing mechanism 120 has a first position and a second position relative to the base station body 110. When the towing mechanism 120 is in the first position, the towing mechanism 120 is attached to the pool wall of the swimming pool. When the towing mechanism 120 is in the second position, the towing mechanism 120 is disposed on the surface of the base station body 110.

[0062] Understandably, the towing mechanism 120 is movably connected to the base station body, so that the towing mechanism 120 can change between a first position and a second position relative to the base station body.

[0063] Understandably, when the towing mechanism 120 is in the second position, the towing mechanism 120 is detached from the water surface.

[0064] Optionally, the towing mechanism 120 can be movably connected to the base station body 110 by, but is not limited to, at least one of a hinge, connecting rod, or lead screw, so that the towing mechanism 120 can be set in the first position to facilitate sending the cleaning robot 310 into the pool, or to facilitate the cleaning robot 310 entering the towing mechanism 120 in the pool to further assist the cleaning robot 310 in getting ashore; the towing mechanism 120 can also be set in the second position to avoid the cleaning robot 310 being immersed in water for a long time, which helps to extend the service life of the cleaning robot 310.

[0065] Understandably, in the embodiments of Figures 1 and 3, the towing mechanism 120 is in a first position, and in the embodiments of Figures 2 and 4, the towing mechanism 120 is in a second position.

[0066] In this embodiment, when the off-water base station 100 assists the cleaning robot 310 in getting out of the pool, the towing mechanism 120 is initially in a first position. The cleaning robot 310 enters the towing mechanism 120 from the pool. The towing mechanism 120 moves relative to the base station body to a second position, thus enabling the cleaning robot 310 to leave the pool and get out. When the off-water base station 100 assists the cleaning robot 310 in entering the pool, the towing mechanism 120 is initially in a second position. The towing mechanism 120 moves relative to the base station body to a first position, and the cleaning robot 310 detaches from the towing mechanism 120 and enters the pool to perform its work. The off-water base station 100 provided in this embodiment assists the cleaning robot 310 in getting out of the pool and entering the pool. On the one hand, it eliminates the need for the user to manually retrieve the cleaning robot 310 from the pool, avoiding potential danger during retrieval and improving the user experience. On the other hand, this avoids prolonged immersion of the cleaning robot 310, extending its service life. Furthermore, the water-off base station 100 enables the cleaning robot 310 to automatically enter the water, eliminating the need for manual operation by the user and further improving the performance of the cleaning robot 310.

[0067] Further, please refer to Figures 5 to 12. The towing mechanism 120 includes a main body 130, a movable baffle 140, and a rotating shaft 150. The main body 130 is movably connected to the base station body 110. The main body 130 has a receiving cavity 131 for accommodating the cleaning robot 310 and an opening 132 communicating with the receiving cavity 131. The movable baffle 140 is located at the opening 132 of the main body 130. The movable baffle 140 is rotatably connected to the inner wall of the main body 130 through the rotating shaft 150 to open or close the opening 132.

[0068] Understandably, the cleaning robot 310 enters the receiving cavity 131 from the outlet, and the cleaning robot 310 also exits from the receiving cavity 131 from the outlet.

[0069] Understandably, in the embodiment of FIG5, the towing mechanism 120 is in a first position, and in the embodiment of FIG6, the towing mechanism 120 is in a second position.

[0070] Understandably, in the embodiments of Figures 7 and 10, the movable baffle 140 is closed relative to the opening 132; in the embodiments of Figures 8 and 11, the movable baffle 140 is in a switching process from closed to open relative to the opening 132; and in the embodiments of Figures 9 and 12, the movable baffle 140 is open relative to the opening 132.

[0071] In this embodiment, the main body 130 is movably connected to the base station main body 110. When the cleaning robot 310 is accommodated in the receiving cavity 131, the main body 130 can drive the cleaning robot 310 to switch between the first position and the second position, thereby bringing the cleaning robot 310 out of the pool or into the pool. In this embodiment, the movable baffle 140 is rotatably connected to the main body 130 via the rotating shaft 150 to open or close the opening 132. When the movable baffle 140 is open relative to the opening 132, the cleaning robot 310 can enter and exit the receiving cavity 131, improving the efficiency of the cleaning robot 310 entering and exiting the receiving cavity 131. When the movable baffle 140 is closed relative to the opening 132, the movable baffle 140 can prevent the cleaning robot 310 from detaching from the receiving cavity 131, thereby improving the structural stability of the cleaning robot 310 disposed on the main body 130.

[0072] Further, referring to Figures 10 to 15, during the opening of the opening 132, the distance between the orthographic projections of the center of the movable baffle 140 and the center of the rotating shaft 150 on the bottom wall of the main body 130 gradually decreases in the direction from the opening 132 towards the interior of the receiving cavity 131. In other words, during the switching process from the movable baffle 140 being closed relative to the opening 132 to being open relative to the opening 132, the distance between the orthographic projection of the center of the movable baffle 140 along a first direction (as shown by the X direction in Figure 10) and the orthographic projection of the center of the rotating shaft 150 along the first direction in a second direction (as shown by the Y direction in Figure 10) gradually decreases. Here, the first direction is the height direction of the main body 130, and the second direction is the direction from the opening 132 towards the interior of the receiving cavity 131; the first direction and the second direction intersect.

[0073] Understandably, during the switching process of the movable baffle 140 closing relative to the opening 132 to opening relative to the opening 132, when the movable baffle 140 is closed relative to the opening 132, the distance between the center of the movable baffle 140 and the center of the rotating shaft 150 on the bottom wall of the main body 130 is the greatest in the direction from the opening 132 to the interior of the receiving cavity 131. In other words, the distance between the orthogonal projection of the center of the movable baffle 140 along the first direction and the orthogonal projection of the center of the rotating shaft 150 along the first direction in the second direction is the greatest.

[0074] Optionally, in some embodiments, the first direction is perpendicular to the second direction.

[0075] In this embodiment, during the switching process of the movable baffle 140 closing relative to the opening 132 to opening relative to the opening 132, the distance between the center of the movable baffle 140 and the center of the rotating shaft 150 projected onto the bottom wall of the main body 130 gradually decreases in the direction from the opening 132 towards the interior of the receiving cavity 131. In other words, the distance between the projection of the center of the movable baffle 140 along the first direction and the projection of the center of the rotating shaft 150 along the first direction in the second direction gradually decreases. This allows the center of the movable baffle 140 to move away from the cleaning robot 310 as it enters the receiving cavity 131, thus preventing the movable baffle 140 from obstructing the movement of the cleaning robot 310 during its rotation relative to the main body 130. This ensures the efficiency of the cleaning robot 310 entering the receiving cavity 131 and improves the efficiency of the water-removing base station 100 in assisting the cleaning robot 310 to go ashore. During the switching process of the movable baffle 140 closing relative to the opening 132 and opening relative to the opening 132, if the distance between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction in the second direction increases, it indicates that during the movement of the cleaning robot 310 into the receiving cavity 131, the center of the movable baffle 140 moves toward the side closer to the cleaning robot 310. In this case, the movable baffle 140 will exert a reaction force on the cleaning robot 310 in the opposite direction of movement to hinder the forward movement of the cleaning robot 310, thereby affecting the efficiency of the cleaning robot 310 entering the receiving cavity 131.

[0076] Optionally, during the switching process of the movable baffle 140 closing relative to the opening 132 to opening relative to the opening 132, the distance between the center of the movable baffle 140 and the center of the rotating shaft 150 projected onto the bottom wall of the main body 130 gradually decreases in the direction from the opening 132 towards the interior of the receiving cavity 131. This can be, but is not limited to, the following: First, the movable baffle 140 is provided in an irregular structure such that, along a first direction, the center of the movable baffle 140 is closer to the receiving cavity 131 than the center of the rotating shaft 150. The bottom wall; secondly, the relative position of the movable baffle 140 and the main body 130 is designed such that when the movable baffle 140 is closed relative to the opening 132, the center of the movable baffle 140 is flush with the center of the rotating shaft 150 along the first direction; thirdly, the relative position of the movable baffle 140 and the main body 130 is designed such that when the movable baffle 140 is closed relative to the opening 132, the center of the movable baffle 140 is closer to the bottom wall of the receiving cavity 131 than the center of the rotating shaft 150 along the first direction.

[0077] Optionally, when the movable baffle 140 is closed relative to the opening 132, the orthographic projection of the center of the movable baffle 140 and the center of the rotating shaft 150 onto the bottom wall of the main body 130 in the direction from the opening 132 towards the interior of the receiving cavity 131 is L1. In other words, the distance between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction in the second direction is L1. When the movable baffle 140 is between closed and open relative to the opening 132, the distance between the center of the movable baffle 140 and the center of the rotating shaft 150 onto the bottom wall of the main body 130 in the direction from the opening 132 towards the interior of the receiving cavity 131 is L1. The orthographic projection on the bottom wall of the main body 130 is L2. In other words, the distance between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction in the second direction is L2. When the movable baffle 140 is closed relative to the opening 132, the orthographic projection of the center of the movable baffle 140 and the center of the rotating shaft 150 on the bottom wall of the main body 130 in the direction from the opening 132 to the interior of the receiving cavity 131 is L3. In other words, the distance between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction in the second direction is L3. The following relationship is satisfied: L3 < L2 < L1.

[0078] Specifically, in Figure 13, the distance L3 between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction in the second direction is 0, so L3 is not shown in Figure 13.

[0079] Optionally, in some embodiments, when the movable baffle 140 is closed relative to the opening 132, the orthographic projection distance between the center of the movable baffle 140 and the center of the rotating shaft 150 on the bottom wall of the main body 130 in the direction from the opening 132 towards the interior of the receiving cavity 131 is equal to the straight-line distance between the center of the movable baffle 140 and the center of the rotating shaft 150. In other words, the distance between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction in the second direction is equal to the straight-line distance from the center of the movable baffle 140 to the center of the rotating shaft 150. Furthermore, when the movable baffle 140 is closed relative to the opening 132, the center of the movable baffle 140 is flush with the center of the rotating shaft 150 in the first direction.

[0080] In this embodiment, when the movable baffle 140 is closed relative to the opening 132, the distance between the orthographic projection of the center of the movable baffle 140 and the center of the rotating shaft 150 on the bottom wall of the main body 130 in the direction from the opening 132 to the interior of the receiving cavity 131 is equal to the straight-line distance between the center of the movable baffle 140 and the center of the rotating shaft 150. In other words, the distance between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction in the second direction is equal to the straight-line distance from the center of the movable baffle 140 to the center of the rotating shaft 150. Therefore, the distance between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction in the second direction is the largest. During the process of the cleaning robot 310 entering the receiving cavity 131, the movable baffle 140 switches from being closed relative to the opening 132 to being open relative to the opening 132. The movable baffle 140 rotates relative to the rotating shaft 150 toward the side away from the cleaning robot 310, so that the center of the movable baffle 140 moves toward the side away from the cleaning robot 310. This satisfies the requirement that the distance between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction gradually decreases in the second direction. This is to avoid the movable baffle 140 obstructing the movement of the cleaning robot 310 during its rotation relative to the main body 130, ensuring the efficiency of the cleaning robot 310 entering the receiving cavity 131 and improving the efficiency of the water-removing base station 100 in assisting the cleaning robot 310 to go ashore.

[0081] Optionally, in some embodiments, when the movable baffle 140 is closed relative to the opening 132, in the direction from the opening 132 toward the interior of the receiving cavity 131, the orthographic projection distance between the center of the movable baffle 140 and the center of the rotating shaft 150 on the bottom wall of the main body 130 is less than the straight-line distance between the center of the movable baffle 140 and the center of the rotating shaft 150. In other words, the distance between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction in the second direction is less than the straight-line distance from the center of the movable baffle 140 to the center of the rotating shaft 150, and along the first direction, the center of the movable baffle 140 is closer to the bottom wall of the receiving cavity 131 than the center of the rotating shaft 150.

[0082] In this embodiment, when the movable baffle 140 is closed relative to the opening 132, in the direction from the opening 132 towards the interior of the receiving cavity 131, the distance between the orthographic projection of the center of the movable baffle 140 and the center of the rotating shaft 150 on the bottom wall of the main body 130 is less than the straight-line distance between the center of the movable baffle 140 and the center of the rotating shaft 150. In other words, the distance between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction in the second direction is less than the straight-line distance from the center of the movable baffle 140 to the center of the rotating shaft 150. Therefore, in the first direction, the center of the movable baffle 140 and the center of the rotating shaft 150 are not aligned. If the movable baffle 140 is closed relative to the opening 132... When closed, the center of the movable baffle 140 is farther from the bottom wall of the receiving cavity 131 than the center of the rotating shaft 150. During the rotation of the movable baffle 140 relative to the rotating shaft 150 toward the direction away from the cleaning robot 310, the center of the movable baffle 140 first moves toward the direction closer to the cleaning robot 310, and then moves toward the direction away from the cleaning robot 310. That is, during the switching process of the movable baffle 140 closing relative to the opening 132 and opening relative to the opening 132, the distance between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction in the second direction first increases and then decreases. This will hinder the movement of the cleaning robot 310, thereby reducing the efficiency of the cleaning robot 310 entering the receiving cavity 131. In this embodiment, when the movable baffle 140 is closed relative to the opening 132, the center of the movable baffle 140 is closer to the bottom wall of the receiving cavity 131 than the center of the rotating shaft 150 along the first direction. During the switching process from the movable baffle 140 being closed relative to the opening 132 to being open relative to the opening 132, the distance between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction in the second direction can be gradually reduced. This is to avoid the movable baffle 140 obstructing the movement of the cleaning robot 310 during its rotation relative to the main body 130, thereby enabling the cleaning robot 310 to enter the towing mechanism 120 with high smoothness and efficiency.

[0083] Optionally, in some embodiments, when the movable baffle 140 is open relative to the opening 132, the orthographic projection distance between the center of the movable baffle 140 and the center of the rotating shaft 150 on the bottom wall of the main body 130 in the direction from the opening 132 toward the interior of the receiving cavity 131 is less than the straight-line distance between the center of the movable baffle 140 and the center of the rotating shaft 150. In other words, the distance between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction in the second direction is less than the straight-line distance from the center of the movable baffle 140 to the center of the rotating shaft 150.

[0084] In this embodiment, when the movable baffle 140 is opened relative to the opening 132, the distance between the orthographic projection of the center of the movable baffle 140 and the center of the rotating shaft 150 on the bottom wall of the main body 130 in the direction from the opening 132 towards the interior of the receiving cavity 131 is less than the straight-line distance between the center of the movable baffle 140 and the center of the rotating shaft 150. In other words, the distance between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction in the second direction is less than the distance between the center of the movable baffle 140 and the center of the rotating shaft 150 along the first direction in the second direction. The straight-line distance from the center of the movable baffle 140 to the center of the rotating shaft 150 facilitates the gradual reduction of the distance between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction in the second direction during the switching process of the movable baffle 140 being closed relative to the opening 132 and being open relative to the opening 132. This prevents the movable baffle 140 from obstructing the movement of the cleaning robot 310 during its rotation relative to the main body 130, thereby enabling the cleaning robot 310 to enter the towing mechanism 120 with high smoothness and efficiency.

[0085] Please refer to Figures 7 and 10. In some embodiments, the towing mechanism 120 further includes a limiting member 160, which is connected to the main body 130 and located on the side of the receiving cavity 131 near the opening 132. The limiting member 160 is used to limit the movable baffle 140.

[0086] In this embodiment, the limiting member 160 is used to limit the position of the movable baffle 140 when the movable baffle 140 is closed relative to the opening 132. When the movable baffle 140 switches from being open relative to the opening 132 to being closed relative to the opening 132 under the action of the reset mechanism 180, the limiting member 160 can prevent the movable baffle 140 from continuing to rotate in a direction away from the receiving cavity 131. This ensures that when the movable baffle 140 is closed relative to the opening 132, the distance between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction in the second direction is less than or equal to the straight-line distance from the center of the movable baffle 140 to the center of the rotating shaft 150. This prevents the movable baffle 140 from obstructing the movement of the cleaning robot 310 during its rotation relative to the main body 130, ensuring the efficiency of the cleaning robot 310 entering the receiving cavity 131 and improving the efficiency of the water-removing base station 100 in assisting the cleaning robot 310 to go ashore.

[0087] Optionally, in some embodiments, the number of limiting members 160 is one; in other embodiments, the number of limiting members 160 is two, the two limiting members 160 are respectively connected to the main body 130 and are spaced apart on two opposite side walls of the receiving cavity 131, the two limiting members 160 cooperate with each other to limit the movable baffle 140.

[0088] Please refer to Figures 18 and 19 together. In some embodiments, the rotating shaft 150 includes a first sub-shaft 151 and a second sub-shaft 152, which are respectively disposed on opposite sides of the main body 130. The movable baffle 140 includes a first rotating part 142, a blocking part 143, and a second rotating part 144 connected together. The first rotating part 142 is rotatably connected to the main body 130 through the first sub-shaft 151, and the second rotating part 144 is rotatably connected to the main body 130 through the second sub-shaft 152. The first rotating part 142 and the second rotating part 144 cooperate to realize the rotation of the blocking part 143 relative to the main body 130, thereby opening or closing the opening 132.

[0089] Understandably, the first sub-shaft 151 and the second sub-shaft 152 are located on opposite sides of the opening 132, and the first rotating part 142 and the second rotating part 144 are located on opposite sides of the opening 132.

[0090] In this embodiment, the first rotating part 142 and the second rotating part 144 are located on opposite sides of the blocking part 143. The first rotating part 142 is rotatably connected to the main body part 130 via the first sub-shaft 151, and the second rotating part 144 is rotatably connected to the main body part 130 via the second sub-shaft 152. The first rotating part 142 and the second rotating part 144 cooperate with each other to enable the blocking part 143 to rotate relative to the main body part 130. Specifically, when the blocking part 143 rotates relative to the main body part 130 toward the direction closer to the receiving cavity 131, the movable baffle 140 opens relative to the opening 132; when the blocking part 143 rotates relative to the main body part 130 toward the direction away from the receiving cavity 131, the movable baffle 140 closes relative to the opening 132.

[0091] Optionally, the first rotating part 142 includes a first sub-part 1421 and a second sub-part 1422 that are bent and connected together. The first sub-part 1421 is rotatably connected to the main body part 130 through the first sub-shaft 151. The second sub-part 1422 is located at the end of the first sub-part 1421 that is away from the first sub-shaft 151. When the movable baffle 140 is closed relative to the opening 132, both the first sub-part 1421 and the second sub-part 1422 abut against the limiting member 160. The second sub-part 1422 is also connected to the blocking part 143.

[0092] Optionally, the second rotating part 144 includes a third sub-part 1441 and a fourth sub-part 1442 that are bent and connected together. The third sub-part 1441 is rotatably connected to the main body part 130 through the second sub-shaft 152. The fourth sub-part 1442 is located at the end of the third sub-part 1441 that is away from the second sub-shaft 152. When the movable baffle 140 is closed relative to the opening 132, both the third sub-part 1441 and the fourth sub-part 1442 abut against the limiting member 160.

[0093] Optionally, referring to FIG20, the blocking part 143 has a guide ramp 1433 to guide the cleaning robot 310 into the receiving cavity 131.

[0094] Optionally, referring to FIG21, in some embodiments, the blocking portion 143 protrudes at least partially from the side of the first sub-portion 1421 away from the second sub-portion 1422, such that when the towing mechanism 120 is in the first position, the first end 3121 of the track wheel 312 contacts the movable baffle 140.

[0095] Understandably, the first rotating part 142 and the second rotating part 144 are disposed on the inner sidewall of the main body part 130.

[0096] Please refer to Figure 22. In some embodiments, the towing mechanism 120 further includes a protective plate 170, which is connected to the main body 130. The protective plate 170 and the main body 130 form a protective cavity 171, which is used to house at least one of the first rotating part 142 and the second rotating part 144.

[0097] In this embodiment, the protective plate 170 and the main body 130 form a protective cavity 171 to protect the first rotating part 142 and / or the second rotating part 144. During the process of the cleaning robot 310 entering the receiving cavity 131 from the opening 132, if the traveling direction of the cleaning robot 310 tilts, the track wheels 312 of the cleaning robot 310 may collide with the first rotating part 142 and / or the second rotating part 144, preventing the first rotating part 142 and / or the second rotating part 144 from rotating relative to the main body 130, thereby preventing the blocking part 143 from rotating relative to the main body 130, and consequently affecting the efficiency of the movable baffle 140 opening relative to the opening 132. The protective plate 170 in this embodiment can protect the first rotating part 142 and / or the second rotating part 144 to prevent the cleaning robot 310 from colliding with the first rotating part 142 and / or the second rotating part 144. It can also prevent the track wheels 312 of the cleaning robot 310 from interfering with the first rotating part 142 and / or the second rotating part 144. This allows the movable baffle 140 to rotate smoothly relative to the main body 130, improving the efficiency of the movable baffle 140 from closing relative to the opening 132 to opening relative to the opening 132. This facilitates the improvement of the efficiency and smoothness of the cleaning robot 310 entering the receiving cavity 131, and ultimately improves the efficiency of the water-removal base station 100 in assisting the cleaning robot 310 to get off the pool.

[0098] Optionally, in some embodiments, there are two protective plates 170, which are respectively connected to the main body 130 and form two independent protective cavities 171. One protective cavity 171 is used to house the first rotating part 142, and the other protective cavity 171 is used to house the second rotating part 144.

[0099] Optionally, in some embodiments, the protective cavity 171 is also used to provide a limiting member 160.

[0100] Please refer to Figures 16 and 19 together. In some embodiments, the blocking part 143 has a first protrusion 1431 on the side opposite to the receiving cavity 131. The first protrusion 1431 is used to engage with the track wheel 312 of the cleaning robot 310 so that the movable baffle 140 opens relative to the opening 132.

[0101] Optionally, the first protrusion 1431 may be, but is not limited to, a dot, a strip, etc. In this embodiment, the first protrusion 1431 is a strip, and the first protrusion 1431 extends along the arrangement direction of the first rotating part 142 and the second rotating part 144.

[0102] Understandably, the first protrusion 1431 is used to engage with the track wheel 312 of the cleaning robot 310, which can be that at least a portion of the first protrusion 1431 engages with at least a portion of the track wheel 312.

[0103] In this embodiment, the blocking part 143 has a first protrusion 1431 on the side opposite to the receiving cavity 131. When the towing mechanism 120 is in the first position and the main body 130 is set against the pool wall, the cleaning robot 310 moves along the pool wall toward the receiving cavity 131. During the movement of the cleaning robot 310, the track wheels 312 of the cleaning robot 310 rotate, and at least a portion of the first protrusion 1431 engages with at least a portion of the track wheels 312 to increase the friction between the track wheels 312 and the movable baffle 140, making it easier for the track wheels 312 to drive the movable baffle 140 to rotate. When the movable baffle 140 rotates relative to the main body 130 toward the receiving cavity 131, the movable baffle 140 opens relative to the opening 132, facilitating the cleaning robot 310 to continue moving into the receiving cavity 131.

[0104] Please also refer to Figure 18. In some embodiments, the blocking portion 143 has a second protrusion 1432 on the side facing the receiving cavity 131. The second protrusion 1432 is used to engage with the track wheel 312 of the cleaning robot 310 so that the movable baffle 140 closes relative to the opening 132.

[0105] Optionally, the second protrusion 1432 may be, but is not limited to, a dot, a strip, etc. In this embodiment, the second protrusion 1432 is a strip, and the second protrusion 1432 extends along the arrangement direction of the first rotating part 142 and the second rotating part 144.

[0106] Understandably, the second protrusion 1432 is used to engage with the track wheel 312 of the cleaning robot 310, which can be that at least a portion of the second protrusion 1432 engages with at least a portion of the track wheel 312.

[0107] In this embodiment, the blocking part 143 has a second protrusion 1432 on the side facing the receiving cavity 131. During the process of the water-removing base station 100 assisting the cleaning robot 310 to get out of the pool, when the towing mechanism 120 is in the first position and the cleaning robot 310 is mostly inside the receiving cavity 131, the track wheels 312 of the cleaning robot 310 continue to rotate to drive the cleaning robot 310 to continue moving. At the same time, at least a portion of the track wheels 312 engages with at least a portion of the second protrusion 1432 to increase the friction between the track wheels 312 and the movable baffle 140, making it easier for the track wheels 312 to drive the movable baffle 140 to rotate. When the movable baffle 140 rotates relative to the main body 130 in a direction away from the receiving cavity 131, the movable baffle 140 switches from being open relative to the opening 132 to being closed relative to the opening 132. When the cleaning robot 310 is fully contained within the receiving cavity 131, the movable baffle 140 is closed relative to the opening 132. The movable baffle 140 is used to prevent the cleaning robot 310 from detaching from the receiving cavity 131, facilitating the towing mechanism 120 to switch from the first position to the second position. This allows the towing mechanism 120 and the cleaning robot 310 to detach from the pool and be positioned on one side of the base station body 110. The water-removed base station 100 assists the cleaning robot 310 in getting out of the pool without requiring the user to manually retrieve it, thus avoiding potential dangers during retrieval, improving the user experience, and preventing the cleaning robot 310 from being submerged for extended periods, thereby extending its service life.

[0108] In some embodiments, the blocking portion 143 has a second protrusion 1432 on the side facing the receiving cavity 131. The second protrusion 1432 is used to engage with the track wheel 312 of the cleaning robot 310 so that the movable baffle 140 opens relative to the opening 132.

[0109] In this embodiment, the blocking part 143 has a second protrusion 1432 on the side facing the receiving cavity 131. During the process of the water-removing base station 100 assisting the cleaning robot 310 to enter the pool, the towing mechanism 120 switches from the second position to the first position relative to the base station body. When the towing mechanism 120 is in the first position, the cleaning robot 310 moves towards the opening 132. At least a portion of the track wheel 312 of the cleaning robot 310 engages with at least a portion of the second protrusion 1432 to increase the friction between the track wheel 312 and the movable baffle 140, making it easier for the track wheel 312 to drive the movable baffle 140 to rotate. When the movable baffle 140 rotates relative to the main body 130 toward the receiving cavity 131, the movable baffle 140 switches from being closed relative to the opening 132 to being open relative to the opening 132. When the movable baffle 140 is in the open state relative to the opening 132, it is convenient for the cleaning robot 310 to detach from the receiving cavity 131 through the opening 132 and enter the pool to work. This process does not require the user to manually place the cleaning robot 310, which helps to improve the user experience.

[0110] Please refer to Figures 23 to 25. In some embodiments, the towing mechanism 120 further includes a reset mechanism 180. The reset mechanism 180 is connected to the rotating shaft 150, the movable baffle 140 and the towing mechanism 120 respectively. The reset mechanism 180 is used to switch the movable baffle 140 from being open relative to the opening 132 to being closed relative to the opening 132.

[0111] In this embodiment, the reset mechanism 180 is connected to the rotating shaft 150, the movable baffle 140, and the towing mechanism 120. The reset mechanism 180 is used to change the movable baffle 140 from being open relative to the opening 132 to being closed relative to the opening 132. After the cleaning robot 310 enters the storage cavity, the reset mechanism 180 can assist the rotation of the movable baffle 140 so that the movable baffle 140 is closed relative to the opening 132, thereby preventing the cleaning robot 310 from detaching from the storage cavity 131. This improves the structural stability of the cleaning robot 310 installed in the storage cavity 131 and also improves the smoothness of the water-removal base station 100 in assisting the cleaning robot 310 to go ashore.

[0112] Please refer to Figure 23. In some embodiments, the reset mechanism 180 is a torsion spring 181. The torsion spring 181 includes a sleeve portion 1811, a first torsion arm 1812, and a second torsion arm 1813. The first torsion arm 1812 and the second torsion arm 1813 are respectively connected to opposite sides of the sleeve portion 1811. The sleeve portion 1811 is sleeved on the outer periphery of the rotating shaft 150. The first torsion arm 1812 abuts against the movable baffle 140, and the second torsion arm 1813 abuts against the main body portion 130.

[0113] In this embodiment, the sleeve portion 1811 is sleeved on the outer periphery of the rotating shaft 150. The first torsion arm 1812 abuts against the movable baffle 140, and the second torsion arm 1813 abuts against the main body portion 130. When an external force is applied, such as the track wheel 312 of the cleaning robot 310 abutting against the movable baffle 140, the movable baffle 140 opens relative to the opening 132. The included angle between the first torsion arm 1812 and the second torsion arm 1813 is small, so that the first torsion arm 1812 and the second torsion arm 1813 abut against each other, thereby creating an interaction force between the movable baffle 140 and the main body portion 130. When the external force is removed, the angle between the first torsion arm 1812 and the second torsion arm 1813 gradually increases, thereby driving the movable baffle 140 to rotate relative to the main body 130 in a direction away from the receiving cavity 131. This allows the movable baffle 140 to switch from opening relative to the opening 132 to closing relative to the opening 132. The torsion spring 181 can assist the rotation of the movable baffle 140 to quickly close the opening 132, preventing the cleaning robot 310 from falling out of the receiving cavity 131. This improves the structural stability of the cleaning robot 310 within the receiving cavity 131 and also enhances the smoothness of the water-removing base station 100 in assisting the cleaning robot 310 to go ashore.

[0114] Please refer to Figures 24 and 25. In some embodiments, the reset mechanism 180 includes a positioning cylinder 182, a linkage 183, a transmission assembly 184, and a rotating wheel 185. The positioning cylinder 182 is rotatably mounted within the receiving cavity 131 and disposed away from the opening 132. The transmission assembly 184 includes a first transmission member 1841, a second transmission member 1842, and a friction belt 1843. The linkage 183 passes through the positioning cylinder 182 and the first transmission member 1841. From the opening 132 towards the interior of the receiving cavity 131, the second transmission member 1842 and the first transmission member 1843... 41 are spaced apart. The friction belt 1843 is sleeved on at least a portion of the outer periphery of the first transmission member 1841 and at least a portion of the outer periphery of the second transmission member 1842. The second transmission member 1842 engages with the rotating wheel 185, and the rotating wheel 185 is connected to the movable baffle 140. When the positioning cylinder 182 rotates, it drives the first transmission member 1841 to rotate through the linkage 183, and drives the second transmission member 1842 to rotate through the friction belt 1843. The second transmission member 1842 engages with the rotating wheel 185 to close the movable baffle 140 relative to the opening 132.

[0115] Optionally, the positioning cylinder 182 is rotatably disposed on the bottom wall of the receiving cavity 131.

[0116] In this embodiment, when the cleaning robot 310 enters the receiving cavity 131, the track wheel 312 of the cleaning robot 310 rotates. When the track wheel 312 contacts the positioning cylinder 182 and before the track wheel 312 stops rotating, the positioning cylinder 182 rotates relative to the main body 130 under the drive of the track wheel 312, so as to avoid the cleaning robot 310 directly hitting the side wall of the receiving cavity 131 and damaging the main body 130, which is beneficial to extending the service life of the towing mechanism 120. Furthermore, when the positioning cylinder 182 rotates relative to the main body 130, the linkage 183 connects the positioning cylinder 182 and the first transmission member 1841, causing the first transmission member 1841 to rotate and drive the second transmission member 1842 to rotate via the friction belt 1843. The second transmission member 1842 engages with the rotating wheel 185 to close the movable baffle 140 relative to the opening 132. The reset mechanism 180 can assist the rotation of the movable baffle 140 to quickly close the opening 132, preventing the cleaning robot 310 from detaching from the receiving cavity 131, improving the structural stability of the cleaning robot 310 installed in the receiving cavity 131, and also improving the smoothness of the water-removing base station 100 in assisting the cleaning robot 310 to go ashore.

[0117] In some embodiments, the towing structure further includes a first guide portion 190 and a second guide portion 210, both of which are connected to the main body portion 130. The first guide portion 190 and the second guide portion 210 are located on opposite sides of the opening 132. The distance between the first guide portion 190 and the second guide portion 210 gradually decreases in the direction from the opening 132 toward the interior of the receiving cavity 131.

[0118] In this embodiment, at the end of the opening 132 opposite to the receiving cavity 131, the distance between the first guide portion 190 and the second guide portion 210 is relatively large, so that the towing mechanism 120 has a large fault tolerance, facilitating the cleaning robot 310 to enter the opening 132 and improving the efficiency of the cleaning robot 310 entering the receiving cavity 131 through the opening 132. Furthermore, from the direction from the opening 132 towards the interior of the receiving cavity 131, the distance between the first guide portion 190 and the second guide portion 210 gradually decreases. In other words, the first guide portion 190 and the second guide portion 210 are inclined to guide the cleaning robot 310 into the opening 132 and continuously correct the direction of travel of the cleaning robot 310, so that the cleaning robot 310 can move towards the interior of the receiving cavity 131 along the second direction, improving the efficiency of the cleaning robot 310 entering the receiving cavity 131, and thus improving the efficiency of the water-removal base station 100 in assisting the cleaning robot 310 to get out of the pool.

[0119] In some embodiments, the towing mechanism 120 further includes a plurality of third protrusions 220, which are spaced apart on the bottom wall of the receiving cavity 131.

[0120] Optionally, the third protrusion 220 may be, but is not limited to, a dot, a ridge, etc. In this embodiment, the third protrusion 220 is a ridge, and the third protrusion 220 extends along the arrangement direction of the first rotating part 142 and the second rotating part 144.

[0121] In this embodiment, the plurality of third protrusions 220 are disposed on the bottom wall of the receiving cavity 131 to increase the friction between the track wheels 312 of the cleaning robot 310 and the main body 130, thereby preventing the cleaning robot 310 from detaching from the receiving cavity 131 and improving the structural stability of the cleaning robot 310 disposed on the main body 130. Specifically, when the towing mechanism 120 is in the first position, the towing mechanism 120 is disposed against the pool wall of the pool, and the main body 130 is placed almost vertically. During the process of the cleaning robot 310 entering the receiving cavity 131, the plurality of third protrusions 220 increase the roughness of the bottom wall of the receiving cavity 131 to increase the sliding friction between the track wheels 312 and the main body 130, thereby improving the efficiency of the cleaning robot 310 entering the receiving cavity 131. When the cleaning robot 310 is fully installed in the receiving cavity 131, the plurality of third protrusions 220 can increase the static friction between the track wheel 312 and the main body 130 to prevent the cleaning robot 310 from coming out of the receiving cavity 131, improve the structural stability of the cleaning robot 310 installed on the main body 130, and thus enable the towing mechanism 120 to have better performance.

[0122] Optionally, in some embodiments, the bottom wall of the receiving cavity 131 also has a relief groove 133, which is connected to the receiving cavity 131 and is used to accommodate the roller brush (not shown in the figure) of the cleaning robot 310. This helps to prevent the roller brush of the cleaning robot 310 from being squeezed and deformed, and helps to extend the service life of the roller brush.

[0123] Please refer to Figures 1 to 4. This application provides a cleaning system 300, which includes a cleaning robot 310 and a water-removing base station 100 provided in this application. The water-removing base station 100 is used to assist the cleaning robot 310 in getting out of the pool and to assist the cleaning robot 310 in entering the pool.

[0124] In the cleaning system 300 provided in this embodiment, the water-removing base station 100 is used to assist the cleaning robot 310 in getting out of the pool and entering the pool. Specifically, when the water-removing base station 100 assists the cleaning robot 310 in getting out of the pool, the towing mechanism 120 is initially in a first position, and the cleaning robot 310 enters the towing mechanism 120 from the pool. The towing mechanism 120 moves relative to the base station body to a second position, thereby enabling the cleaning robot 310 to leave the pool and get out. When the water-removing base station 100 assists the cleaning robot 310 in entering the pool, the towing mechanism 120 is initially in the second position, and the towing mechanism 120 moves relative to the base station body to a first position. The cleaning robot 310 then detaches from the towing mechanism 120 and enters the pool to perform its work. In the cleaning system 300 provided in this embodiment, the off-water base station 100 is used to assist the cleaning robot 310 in getting out of the pool and entering the pool, eliminating the need for the user to manually retrieve the cleaning robot 310 from the pool, thus avoiding potential dangers during retrieval and improving the user experience. Furthermore, it prevents the cleaning robot 310 from being submerged for extended periods, extending its service life.

[0125] In the cleaning system 300 provided in this embodiment, the towing mechanism 120 includes a main body 130, a movable baffle 140, and a rotating shaft 150. The main body 130 is movably connected to the base station body 110. The main body 130 has a receiving cavity 131 for accommodating a cleaning robot 310. The receiving cavity 131 has an opening 132 on the side near the movable baffle 140. The movable baffle 140 is rotatably connected to the main body 130 via the rotating shaft 150 to open or close the opening 132. The main body 130 is movably connected to the base station body 110. When the cleaning robot 310 is accommodated in the receiving cavity 131, the main body 130 can drive the cleaning robot 310 to switch between a first position and a second position to bring the cleaning robot 310 out of the pool or into the pool. In this embodiment, the movable baffle 140 is rotatably connected to the main body 130 via the rotating shaft 150 to open or close the opening 132. When the movable baffle 140 is open relative to the opening 132, the cleaning robot 310 can enter and exit the receiving cavity 131, improving the efficiency of the cleaning robot 310 entering and exiting the receiving cavity 131. When the movable baffle 140 is closed relative to the opening 132, the movable baffle 140 can prevent the cleaning robot 310 from detaching from the receiving cavity 131, thereby improving the structural stability of the cleaning robot 310 disposed on the main body 130.

[0126] In the cleaning system 300 provided in this embodiment, during the switching process of the movable baffle 140 being closed relative to the opening 132 to being open relative to the opening 132, the distance between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction in the second direction gradually decreases. The first direction is the height direction of the main body 130, and the second direction is the direction in which the opening 132 points to the interior of the receiving cavity 131. The first direction and the second direction intersect. During the switching process of the movable baffle 140 closing relative to the opening 132 and opening relative to the opening 132, the distance between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction in the second direction gradually decreases. This allows the center of the movable baffle 140 to move away from the cleaning robot 310 as it enters the receiving cavity 131, thus preventing the movable baffle 140 from obstructing the movement of the cleaning robot 310 during its rotation relative to the main body 130. This ensures the efficiency of the cleaning robot 310 entering the receiving cavity 131 and improves the efficiency of the water-removing base station 100 in assisting the cleaning robot 310 to go ashore. During the switching process of the movable baffle 140 closing relative to the opening 132 and opening relative to the opening 132, if the distance between the orthographic projection of the center of the movable baffle 140 along the first direction and the orthographic projection of the center of the rotating shaft 150 along the first direction in the second direction increases, it indicates that during the movement of the cleaning robot 310 into the receiving cavity 131, the center of the movable baffle 140 moves toward the side closer to the cleaning robot 310. In this case, the movable baffle 140 will exert a reaction force on the cleaning robot 310 in the opposite direction of movement to hinder the forward movement of the cleaning robot 310, thereby affecting the efficiency of the cleaning robot 310 entering the receiving cavity 131.

[0127] In some embodiments, the cleaning robot 310 includes a cleaning body 311 and track wheels 312. The track wheels 312 are rotatably connected to the cleaning body 311 and are used to drive the cleaning body 311 to move. When the cleaning robot 310 enters the receiving cavity 131, the rotation direction of the track wheels 312 is a first rotation direction. When the cleaning robot 310 exits the receiving cavity 131, the rotation direction of the track wheels 312 is a second rotation direction, and the first rotation direction is opposite to the second rotation direction.

[0128] In this embodiment, when the cleaning robot 310 enters the receiving cavity 131, the track wheel 312 rotates along the first rotation direction to drive the cleaning robot 310 to travel in the same direction as the second direction. The track wheel 312 contacts the movable baffle 140 and causes the movable baffle 140 to rotate in a direction away from the receiving cavity 131, so that the movable baffle 140 switches from being open relative to the opening 132 to being closed relative to the opening 132. Conversely, when the cleaning robot 310 exits the receiving cavity 131, the track wheel 312 rotates along the first rotation direction to drive the cleaning robot 310 to travel in the opposite direction to the second direction. The track wheel 312 contacts the movable baffle 140 and causes the movable baffle 140 to rotate in a direction closer to the receiving cavity 131, so that the movable baffle 140 switches from being closed relative to the opening 132 to being open relative to the opening 132.

[0129] Optionally, in some embodiments, when the cleaning robot 310 enters the receiving cavity 131, the first rotation direction is clockwise, and the rotation direction of the movable baffle 140 relative to the main body 130 is counterclockwise; when the cleaning robot 310 exits the receiving cavity 131, the second rotation direction is counterclockwise, and the rotation direction of the movable baffle 140 relative to the main body 130 is clockwise.

[0130] Optionally, in some embodiments, when the cleaning robot 310 moves toward the opening 132, the cleaning robot 310 can jump directly over the movable baffle 140 to allow the cleaning robot 310 to detach from the receiving cavity 131.

[0131] Please refer to Figure 16. In some embodiments, during the process of the cleaning robot 310 entering the receiving cavity 131, the end of the track wheel 312 near the movable baffle 140 is the first end 3121, and the first end 3121 contacts the movable baffle 140. In other words, when the towing mechanism 120 is in the first position, the end of the track wheel 312 near the movable baffle 140 is the first end 3121, and the first end 3121 contacts the movable baffle 140.

[0132] Understandably, when the towing mechanism 120 is in the first position, the towing mechanism 120 is disposed in contact with the pool wall; in other words, the main body 130 is disposed in contact with the pool wall.

[0133] Optionally, the water-free base station 100 includes a reset mechanism 180 such that when the movable baffle 140 is opened relative to the opening 132, the movable baffle 140 can automatically return to being closed relative to the opening 132.

[0134] Optionally, in some embodiments, the track wheels 312 of the cleaning robot 310 can engage with the movable baffle 140, so that the movable baffle 140 can rotate relative to the main body 130, thereby enabling the movable baffle 140 to switch between being open relative to the opening 132 and being closed relative to the opening 132.

[0135] Optionally, the track wheel 312 can rotate clockwise or counterclockwise relative to the cleaning body 311, causing the cleaning robot 310 to move forward or backward.

[0136] In this embodiment, when the towing mechanism 120 is in the first position, before the cleaning robot 310 enters the receiving cavity 131, the movable baffle 140 is closed relative to the opening 132. Further, the cleaning robot 310 moves towards the receiving cavity 131, and its first end 3121 contacts the movable baffle 140, facilitating the engagement of the cleaning robot 310's track wheels 312 with the movable baffle 140. This allows the movable baffle 140 to rotate relative to the main body 130, switching from closed relative to the opening 132 to open relative to the opening 132, thus facilitating the cleaning robot 310's entry into the receiving cavity 131. After the cleaning robot 310 has fully entered the receiving cavity 131, the movable baffle 140 is no longer subjected to the force of the track wheels 312. The movable baffle 140 can then close relative to the opening 132 under the action of the reset mechanism 180 to prevent the cleaning robot 310 from detaching from the receiving cavity 131. As the track wheel 312 moves along the pool wall toward the receiving cavity 131, the cleaning robot 310 needs to climb a certain height along the pool wall due to the thickness of the main body 130. The first end 3121 is the end of the track wheel 312 near the movable baffle 140. During the movement of the cleaning robot 310 toward the receiving cavity 131, the first end 3121 should be the first to contact the movable baffle 140. If the first end 3121 fails to contact the movable baffle 140, as the cleaning robot 310 moves, the first end 3121 may abut against the side of the movable baffle 140 facing the pool wall, potentially pushing the movable baffle 140 and the main body 130 away from the pool wall, and ultimately causing the cleaning robot 310 to become stuck between the main body 130 and the pool wall, increasing the risk of wear and tear on the cleaning robot 310 and shortening its service life. In this embodiment, as the cleaning robot 310 moves toward the receiving cavity 131, the first end 3121 contacts the movable baffle 140, so that during the rotation of the track wheel 312, the track wheel 312 can easily engage with the movable baffle 140, and the movable baffle 140 can switch from a closed state relative to the opening 132 to an open state relative to the opening 132. The opening 132 is open, so that the cleaning robot 310 can enter the receiving cavity 131 through the opening 132 and be received in the receiving cavity 131.In this embodiment, the first end 3121 contacts the movable baffle 140 to prevent the cleaning robot 310 from lifting the movable baffle 140 and the main body 130 during the process of entering the receiving cavity 131. This improves the smoothness and efficiency of the cleaning robot 310 entering the receiving cavity 131, enhances the performance of the water-free base station 100, and also helps to extend the service life of the cleaning robot 310.

[0137] Referring to Figure 17, in some embodiments, during the process of the cleaning robot 310 entering the receiving cavity 131, the end of the movable baffle 140 near the bottom wall of the receiving cavity 131 is the second end 141, and the vertical distance from the first end 3121 to the bottom wall of the receiving cavity 131 is greater than or equal to the vertical distance from the second end 141 to the bottom wall of the receiving cavity 131. In other words, when the towing mechanism 120 is in the first position, the end of the movable baffle 140 near the pool wall is the second end 141, and the vertical distance from the first end 3121 to the pool wall is greater than or equal to the vertical distance from the second end 141 to the pool wall.

[0138] Understandably, along the first direction, the first end 3121 is closer to the bottom wall of the receiving cavity 131 than the second end 141.

[0139] Understandably, the end of the movable baffle 140 near the pool wall is the second end 141, which is the part where the movable baffle 140 engages with the track wheel 312 of the cleaning robot 310. In other words, when the movable baffle 140 includes a connected first rotating part 142, a blocking part 143, and a second rotating part 144, and the towing mechanism 120 is in the first position, the second end 141 is the end of the blocking part 143 near the pool wall.

[0140] In this embodiment, when the towing mechanism 120 is in the first position, the vertical distance from the first end 3121 to the pool wall is greater than or equal to the vertical distance from the second end 141 to the pool wall. Therefore, even if the main body 130 of the towing mechanism 120 occupies a certain thickness, during the process of the cleaning robot 310 climbing a certain height along the pool wall, it can be ensured that the first end 3121 can contact the second end 141, that is, that the first end 3121 can contact the movable baffle 140. When the cleaning robot 310 moves towards the receiving cavity 131, the track wheel 312 rotates and engages with the movable baffle 140, thereby switching the movable baffle 140 from a closed state relative to the opening 132 to an open state relative to the opening 132, so that the opening 132 is open, and the cleaning robot 310 enters the receiving cavity 131 through the opening 132 and is accommodated within the receiving cavity 131. If the vertical distance from the first end 3121 to the pool wall is less than the vertical distance from the second end 141 to the pool wall, when the cleaning robot 310 moves towards the receiving cavity 131, the first end 3121 and the second end 141 will be misaligned. This will prevent the first end 3121 from contacting the movable baffle 140. As the cleaning robot 310 continues to move, this increases the risk that the cleaning robot 310 will lift the movable baffle 140 and the main body 130 when entering the receiving cavity 131.
