Description

Technical Field

[0001] This application relates to the field of robotics technology, specifically to an off-water base station. Background Technology

[0002] Pool cleaning robots, as convenient automated devices, are widely used in the cleaning and maintenance of pools. After cleaning, the robot is usually charged in water. However, charging in water poses a risk of electric leakage, and prolonged immersion reduces the robot's lifespan. Furthermore, debris inside the robot can easily cause secondary contamination of the pool during immersion. Therefore, it is necessary to install a water-removal station to take the robot out of the water and avoid prolonged immersion. Utility Model Content

[0003] In view of this, this application provides a water-off-water base station, which facilitates the removal of a water pool cleaning robot from the water pool and has good usability and safety performance.

[0004] This application provides a water-removing base station, which includes a base station body, a towing mechanism, and a drive mechanism. The towing mechanism has an extended position that extends at least partially below the liquid surface and a retracted position located on the base station body. The towing mechanism is used to drive a water tank cleaning robot to leave or enter the water tank. The drive mechanism is disposed on the base station body and includes a drive unit and a swing arm assembly that is driveably connected thereto. The swing arm assembly is located on both sides of the base station body and is rotatably connected to the base station body and the towing mechanism, respectively. The drive unit drives the towing mechanism to move between the extended position and the retracted position.

[0005] Furthermore, the swing arm assembly includes a first swing arm and a second swing arm, which are respectively located on the outer sides of the base station body. One end of each of the first swing arm and the second swing arm is rotatably connected to the base station body, and the other end of each of the first swing arm and the second swing arm is rotatably connected to the towing mechanism.

[0006] Furthermore, the swing arm assembly also includes a first rotating shaft and a second rotating shaft. The drive unit is connected to the first rotating shaft to drive the first rotating shaft to rotate. The first rotating shaft is connected to the first swing arm and the second swing arm respectively. The two ends of the second rotating shaft are connected to the first swing arm and the second swing arm respectively.

[0007] Furthermore, the first rotating shaft includes a first sub-shaft and a second sub-shaft, which are located on opposite sides of the driving unit. The driving unit includes a first output terminal and a second output terminal. The two ends of the first sub-shaft are connected to the first output terminal and the first swing arm, respectively, and the two ends of the second sub-shaft are connected to the second output terminal and the second swing arm, respectively.

[0008] Furthermore, the first rotating axis is arranged parallel to the second rotating axis.

[0009] Furthermore, the towing mechanism has a connecting end and a free end, the connecting end being connected to the swing arm assembly, and the free end being supported on the base station body when the towing mechanism moves between the deployed position and the retracted position.

[0010] Furthermore, a support component is rotatably provided on the base station body, and when the towing mechanism moves between the extended position and the retracted position, the free end is rolled and supported on the support component.

[0011] Furthermore, the load-bearing component includes a rolling cylinder and a limiting groove formed on its surface, and the bottom of the towing mechanism is formed with a limiting protrusion adapted to the limiting groove. When the towing mechanism moves between the extended position and the retracted position, the limiting protrusion is located in the limiting groove.

[0012] Furthermore, the drive unit includes a drive motor and a reduction gearbox, the output shaft of the drive motor is connected to the reduction gearbox, and the output actuator of the reduction gearbox is connected to the swing arm assembly.

[0013] Furthermore, the towing mechanism is configured with a receiving cavity for accommodating the pool cleaning robot. One end of the receiving cavity is provided with an opening for the pool cleaning robot to enter the receiving cavity. A movable baffle for opening or closing the opening is movably provided at the opening.

[0014] In the water-removing base station provided in this application, the drive unit provides power to the swing arm assembly, causing the swing arm assembly to rotate relative to the base station body. Further, the swing arm assembly drives the towing mechanism to rotate, enabling the towing mechanism to switch between an extended position and a retracted position. Specifically, the towing mechanism accommodates a water tank cleaning robot. When the water tank cleaning robot completes its cleaning task or needs charging, the towing mechanism is in the extended position, allowing the water tank cleaning robot in the water tank to enter the towing mechanism. Through the drive unit and the transmission of the swing arm assembly, the towing mechanism switches to the retracted position, thereby enabling the water tank cleaning robot to leave the water tank. This facilitates charging the water tank cleaning robot, avoids the risk of electric leakage while charging in the water tank, prevents the water tank cleaning robot from being submerged in the water for extended periods, thus reducing its service life, and also prevents the water tank from being contaminated by debris inside the water tank. The off-water base station provided in this application facilitates the removal of the pool cleaning robot from the pool, has good usability and safety performance, and enables the pool cleaning robot to have a long service life.

[0032] Pool cleaning robots, as convenient automated devices, are widely used in the cleaning and maintenance of pools. After cleaning, the robot is usually charged in water. However, charging in water poses a risk of electric leakage, and prolonged immersion reduces the robot's lifespan. Furthermore, debris inside the robot can easily cause secondary contamination of the pool during soaking. Manually removing the robot from the water is dangerous and inconvenient. Therefore, it is necessary to install a water-removal station to remove the robot from the water, preventing it from being submerged for extended periods.

[0033] Please see Figures 1 to 4 This application provides a water-removing base station 100, which includes a base station body 110, a towing mechanism 120, and a drive mechanism 130. The towing mechanism 120 has an extended position that extends at least partially below the liquid surface and a retracted position located on the base station body 110. The towing mechanism 120 is used to drive a water tank cleaning robot to leave or enter the water tank. The drive mechanism 130 is disposed on the base station body 110. The drive mechanism 130 includes a drive unit 131 and a swing arm assembly 132 that is rotatably connected to it. The swing arm assembly 132 is located on both sides of the base station body 110 and is rotatably connected to the base station body 110 and the towing mechanism 120, respectively. The drive unit 131 drives the towing mechanism 120 to move between the extended position and the retracted position.

[0034] Understandably, in this application Figure 1 Implementation Examples and Figure 4 In this embodiment, the towing mechanism 120 is in the retracted position; in this application Figure 2 Implementation Examples and Figure 3 In this embodiment, the towing mechanism 120 is in the deployed position.

[0035] Understandably, the base station body 110 and the towing mechanism 120 are rotatably connected through the swing arm assembly 132, and the towing mechanism 120 moves between the deployed position and the retracted position under the drive of the drive unit 131.

[0036] Understandably, when the towing mechanism 120 is in the deployed position, the towing mechanism 120 extends at least partially below the liquid surface, for the purpose of allowing the pool cleaning robot to contact the pool, and for the pool cleaning robot to enter the towing mechanism 120 from the pool, or for the pool cleaning robot to detach from the towing mechanism 120 and enter the pool.

[0037] Understandably, when the towing mechanism 120 is in the retracted position, the pool cleaning robot is located inside the towing mechanism 120, and the pool cleaning robot leaves the pool.

[0038] Understandably, the towing mechanism 120 has a receiving cavity 124 for accommodating the pool cleaning robot.

[0039] In the water-free base station 100 provided in this embodiment, the driving unit 131 is used to provide power to the swing arm assembly 132 so that the swing arm assembly 132 rotates relative to the base station body 110. Furthermore, the swing arm assembly 132 drives the towing mechanism 120 to rotate so as to realize the towing mechanism 120 switching between the extended position and the retracted position. Specifically, the towing mechanism 120 is used to accommodate the pool cleaning robot. When the pool cleaning robot completes its cleaning task or needs charging, the towing mechanism 120 is in the extended position, allowing the pool cleaning robot in the pool to enter the towing mechanism 120. Through the drive unit 131 and the transmission of the swing arm assembly 132, the towing mechanism 120 switches to the retracted position, thereby enabling the pool cleaning robot to leave the pool. This facilitates charging the pool cleaning robot, avoiding the risk of electric leakage when charging in the pool, preventing the pool cleaning robot from being submerged in the pool for a long time, thus reducing its service life, and preventing the pool cleaning robot's internal debris from contaminating the pool. The off-water base station 100 provided in this embodiment facilitates the removal of the pool cleaning robot from the pool, has good usability and safety performance, and gives the pool cleaning robot a long service life.

[0040] Similarly, when the pool cleaning robot is fully charged or needs to perform a cleaning task, the drive unit 131 drives the swing arm assembly 132 to rotate. The swing arm assembly 132 rotates relative to the towing mechanism 120, so that the towing mechanism 120 switches from the retracted position to the extended position. The towing mechanism 120 extends at least partially below the liquid surface, making it easier for the pool cleaning robot to enter the pool and perform the cleaning task.

[0041] Optionally, please also see Figure 5The base station body 110 also includes a charging base 111, which protrudes from the top of the base station body 110 and is equipped with a wireless charging transmitter. The pool cleaning robot is equipped with a wireless charging receiver. When the towing mechanism 120 is in the retracted position, the charging base 111 is used to charge the pool cleaning robot.

[0042] In this embodiment, the charging base 111 protrudes from the top of the base station body 110, so that when the towing mechanism 120 is in the retracted position, the charging base 111 is closer to the bottom of the pool cleaning robot, making the wireless charging transmitter closer to the wireless charging receiver of the pool cleaning robot, thereby enabling the base station body 110 to provide a stable power supply to the pool cleaning robot. Compared to the scheme of charging the pool cleaning robot in the pool, the water-off-water base station 100 in this embodiment charges the pool cleaning robot when it is out of the water. On the one hand, it avoids the risk of leakage when charging in the pool, and on the other hand, the pool cleaning robot does not need to waste power hovering in the pool, which helps to improve the energy utilization rate of the pool cleaning robot.

[0043] Furthermore, please also refer to Figure 6 The towing mechanism 120 also has a through-hole 127 that penetrates the bottom wall of the towing mechanism 120. When the towing mechanism 120 is in the retracted position, the through-hole 127 corresponds to the charging base 111 and the wireless charging receiver of the pool cleaning robot. The charging base 111 can pass through the through-hole 127 and is partially located in the receiving cavity 124 of the towing mechanism 120, which is conducive to the proximity of the wireless charging transmitter and the wireless charging receiver, and improves the efficiency and stability of the water base station 100 in charging the pool cleaning robot.

[0044] In some embodiments, the swing arm assembly 132 includes a first swing arm 1321 and a second swing arm 1322. The first swing arm 1321 and the second swing arm 1322 are respectively located on the outer sides of the base station body 110. One end of each of the first swing arm 1321 and the second swing arm 1322 is rotatably connected to the base station body 110, and the other end of each of the first swing arm 1321 and the second swing arm 1322 is rotatably connected to the towing mechanism 120.

[0045] Understandably, the opposite ends of the first swing arm 1321 are rotatably connected to the base station body 110 and the towing mechanism 120, respectively, and the opposite ends of the second swing arm 1322 are rotatably connected to the base station body 110 and the towing mechanism 120, respectively.

[0046] In this embodiment, the first swing arm 1321 and the second swing arm 1322 are located on the outer sides of the base station body 110, and one end of each of the first swing arm 1321 and the second swing arm 1322 is rotatably connected to the base station body 110. Specifically, the first swing arm 1321 and the second swing arm 1322 rotate relative to the base station body 110 under the drive of the drive unit 131. When the first swing arm 1321 and the second swing arm 1322 rotate, the other end of each of the first swing arm 1321 and the second swing arm 1322 rotates relative to the towing mechanism 120, thereby causing the towing mechanism 120 to move relative to the base station body 110, and thus realizing the movement of the towing mechanism 120 between the deployed position and the retracted position. The first swing arm 1321 and the second swing arm 1322 cooperate with each other to improve the stability of moving the towing mechanism 120, ensure that the forces on both sides of the towing mechanism 120 are uniform and synchronous, and improve the smoothness of the towing mechanism 120 when switching between the extended position and the retracted position.

[0047] In some embodiments, the swing arm assembly 132 further includes a first rotating shaft 1323 and a second rotating shaft 1324. The drive unit 131 is connected to the first rotating shaft 1323 to drive the first rotating shaft 1323 to rotate. The first rotating shaft 1323 is connected to the first swing arm 1321 and the second swing arm 1322 respectively. The two ends of the second rotating shaft 1324 are connected to the first swing arm 1321 and the second swing arm 1322 respectively.

[0048] Understandably, the first rotating shaft 1323 is located further away from the towing mechanism 120 than the second rotating shaft 1324.

[0049] Understandably, the first rotating shaft 1323 connects the first swing arm 1321 and the second swing arm 1322 to the same end near the base station body 110, and the second rotating shaft 1324 connects the first swing arm 1321 and the second swing arm 1322 to the same end near the towing mechanism 120.

[0050] Understandably, the first rotating shaft 1323 passes through the base station body 110 and at least partially protrudes from the base station body 110 to connect with the first swing arm 1321 and / or the second swing arm 1322.

[0051] In this embodiment, the first rotating shaft 1323 is connected to the first swing arm 1321 and the second swing arm 1322 respectively. When the driving unit 131 is turned on, the driving unit 131 drives the first rotating shaft 1323 to rotate, and the first rotating shaft 1323 drives the first swing arm 1321 and the second swing arm 1322 to rotate synchronously. In addition, both ends of the second rotating shaft 1324 are connected to the first swing arm 1321 and the second swing arm 1322 respectively, which can drive the first swing arm 1321 and the second swing arm 1322 to rotate synchronously. The relative position of 1322 is defined, which can further improve the synchronization of the rotation process of the first swing arm 1321 and the second swing arm 1322, so that the swing arm assembly 132 has better rigidity. Even if the towing mechanism 120 and the water cleaning robot it carries are heavy, the swing arm assembly 132 can rotate relative to the towing mechanism 120 and drive the towing mechanism 120 to rotate relative to the base station body 110, thereby improving the performance of the water-removing base station 100 in driving the water cleaning robot to leave or enter the water pool.

[0052] Please see also Figure 7 and Figure 8 In some embodiments, the first rotating shaft 1323 includes a first sub-shaft 1325 and a second sub-shaft 1326. The first sub-shaft 1325 and the second sub-shaft 1326 are respectively located on opposite sides of the driving unit 131. The driving unit 131 includes a first output end and a second output end. The two ends of the first sub-shaft 1325 are respectively connected to the first output end and the first swing arm 1321, and the two ends of the second sub-shaft 1326 are respectively connected to the second output end and the second swing arm 1322.

[0053] In this embodiment, along the arrangement direction of the first swing arm 1321 and the second swing arm 1322, the first swing arm 1321, the first sub-shaft 1325, the first output end, the second output end, the second sub-shaft 1326 and the second swing arm 1322 are arranged in sequence.

[0054] In this embodiment, when the drive unit 131 is activated, the first output terminal of the drive unit 131 drives the first sub-shaft 1325 to rotate. The first sub-shaft 1325 drives the first swing arm 1321 to rotate, thereby causing the first swing arm 1321 to rotate relative to the base station body 110. Similarly, the second output terminal of the drive unit 131 drives the second sub-shaft 1326 to rotate. The second sub-shaft 1326 drives the second swing arm 1322 to rotate, thereby causing the second swing arm 1322 to rotate relative to the base station body 110. The first sub-shaft 1325 and the second sub-shaft 1326 cooperate with each other so that the drive unit 131 can synchronously drive the first swing arm 1321 and the second swing arm 1322 to rotate, improving the synchronicity of the movement of the towing mechanism 120 driven by the first swing arm 1321 and the second swing arm 1322, thereby improving the smoothness of the towing mechanism 120 switching between the deployed position and the retracted position.

[0055] Optionally, please also see Figure 9 The first swing arm 1321 has a first through groove 1327 at the end near the first sub-shaft 1325, and the end of the first sub-shaft 1325 away from the drive unit 131 has a first protrusion (not shown in the figure). The first protrusion of the first sub-shaft 1325 abuts against the inner wall of the first through groove 1327. The second swing arm 1322 has a second through groove 1328 at the end near the second sub-shaft 1326, and the end of the second sub-shaft 1326 away from the drive unit 131 has a second protrusion (not shown in the figure). The second protrusion of the second sub-shaft 1326 abuts against the inner wall of the second through groove 1328.

[0056] Understandably, the first through slot 1327 and the second through slot 1328 are arranged opposite to each other.

[0057] In this embodiment, the first protrusion of the first sub-shaft 1325 abuts against the inner wall of the first through groove 1327, so the first sub-shaft 1325 and the first swing arm 1321 abut against each other, and the first through groove 1327 limits the first protrusion, which is conducive to transmitting a larger torque. Similarly, the second protrusion of the second sub-shaft 1326 abuts against the inner wall of the second through groove 1328, the second sub-shaft 1326 and the second swing arm 1322 abut against each other, and the second through groove 1328 limits the second protrusion, which is conducive to transmitting a larger torque, thereby driving the swing arm assembly 132 to rotate relative to the base station body 110, and then realizing the switching of the towing mechanism 120 between the extended position and the retracted position.

[0058] Optionally, the swing arm assembly 132 further includes a first fastener (not shown) and a second fastener (not shown). The first fastener is sequentially inserted through the first swing arm 1321 and the first sub-shaft 1325 to fix the relative position of the first swing arm 1321 and the first sub-shaft 1325. The second fastener is sequentially inserted through the second swing arm 1322 and the second sub-shaft 1326 to fix the relative position of the second swing arm 1322 and the second sub-shaft 1326.

[0059] Optionally, the first fastener may be, but is not limited to, a screw, and the second fastener may be, but is not limited to, a screw.

[0060] In this embodiment, the first fastener is sequentially inserted through the inner wall of the first through slot 1327 of the first swing arm 1321 and the first sub-shaft 1325. The first fastener is only subjected to axial force and is not used to transmit torque, which helps to extend the service life of the first fastener and improves the fastening effect of the first fastener on the first swing arm 1321 and the first sub-shaft 1325. Similarly, the second fastener is sequentially inserted through the inner wall of the second through slot 1328 of the second swing arm 1322 and the second sub-shaft 1326. The second fastener is only subjected to axial force and is not used to transmit torque, which helps to extend the service life of the second fastener and improves the fastening effect of the second fastener on the second swing arm 1322 and the second sub-shaft 1326.

[0061] In some embodiments, the first rotating shaft 1323 and the second rotating shaft 1324 are arranged in parallel.

[0062] In this embodiment, the first rotation axis 1323 and the second rotation axis 1324 are arranged in parallel. The swing arm assembly 132, constrained by the first and second rotation axes 1323 and 1324, achieves independent rotation around the two axes, thereby enabling the towing mechanism 120 to reach a larger spatial range, i.e., switching between the retracted and extended positions. Furthermore, the parallel arrangement of the first and second rotation axes 1323 and 1324 better constrains the movement of the first and second swing arms 1321 and 1322, avoiding movement errors or jamming due to axial misalignment. This allows the towing mechanism 120 to move more smoothly relative to the base station body 110, improving the usability of the water-removing base station 100.

[0063] In some embodiments, the towing mechanism 120 has a connecting end 121 and a free end 122, the connecting end 121 being connected to the swing arm assembly 132, and the free end 122 being supported on the base station body 110 when the towing mechanism 120 moves between the extended position and the retracted position.

[0064] Understandably, the free end 122 is further away from the second rotation axis 1324 than the connected end 121.

[0065] Understandably, the connecting end 121 is rotatably connected to the swing arm assembly 132.

[0066] In this embodiment, when the towing mechanism 120 moves between the extended position and the retracted position, the first swing arm 1321 and the second swing arm 1322 rotate relative to the base station body 110 and relative to the towing mechanism 120, so that the free end 122 is supported on the base station body 110 and slides relative to the base station body 110, thereby changing the relative position of the towing mechanism 120 and the base station body 110. In this embodiment, the base station body 110 can provide support for the free end 122, allowing the towing mechanism 120 to move along the base station body 110, which helps to improve the efficiency of the towing mechanism 120 moving relative to the base station body 110.

[0067] Please see also Figure 10 In some embodiments, a support component 140 is rotatably provided on the base station body 110, and the free end 122 is rolledly supported on the support component 140 when the towing mechanism 120 moves between the extended position and the retracted position.

[0068] Understandably, the carrier component 140 can roll relative to the base station body 110.

[0069] In this embodiment, when the towing mechanism 120 moves between the extended position and the retracted position, the free end 122 is supported on the bearing assembly 140. When the first swing arm 1321 and the second swing arm 1322 rotate relative to the base station body 110 and relative to the towing mechanism 120, the bearing assembly 140 rolls, causing the free end 122 to slide relative to the bearing assembly 140. This changes the relative position of the towing mechanism 120 and the base station body 110. The sliding of the towing mechanism 120 relative to the bearing assembly 140 has better smoothness, which is beneficial to further improving the efficiency of the towing mechanism 120 moving relative to the base station body 110.

[0070] In some embodiments, the carrier assembly 140 includes a rolling cylinder 141 and a limiting groove 142 formed on its surface, and the bottom of the towing mechanism 120 is provided with a limiting protrusion 123 adapted to the limiting groove 142. When the towing mechanism 120 moves between the extended position and the retracted position, the limiting protrusion 123 is located in the limiting groove 142.

[0071] In this embodiment, when the towing mechanism 120 moves between the extended position and the retracted position, the free end 122 is rolled and supported by the rolling cylinder 141. More specifically, the limiting protrusion 123 of the towing mechanism 120 is located in the limiting groove 142 of the rolling cylinder 141. When the rolling cylinder 141 rolls, the limiting protrusion 123 is always located within the limiting groove 142. This embodiment, through the cooperation of the limiting protrusion 123 and the limiting groove 142, limits and guides the relative movement direction of the towing mechanism 120 and the base station body 110, improving the accuracy of the towing mechanism 120's movement relative to the base station body 110, preventing deviation of the towing mechanism 120's movement direction relative to the base station body 110, improving the accuracy of the towing mechanism 120's switching between the extended and retracted positions, and improving the usability of the water-free base station 100.

[0072] In some embodiments, please also refer to Figure 11 The drive unit 131 includes a drive motor 1313 and a reduction gearbox 1314. The output shaft of the drive motor 1313 is connected to the reduction gearbox 1314, and the output actuator of the reduction gearbox 1314 is connected to the swing arm assembly 132.

[0073] In this embodiment, the output shaft of the drive motor 1313 is connected to the reduction gearbox 1314. The drive motor 1313 typically rotates at a relatively high speed, and the reduction gearbox 1314 reduces the speed at which the drive motor 1313 drives outward. When the output actuator of the reduction gearbox 1314 is connected to the swing arm assembly 132, the speed transmitted to the swing arm assembly 132 decreases, thereby reducing the swing amplitude or frequency of the swing arm assembly 132 and improving the stability of the towing mechanism 120 relative to the base station body 110.

[0074] Understandably, the output actuator of the gearbox 1314 includes the first output terminal and the second output terminal.

[0075] Optionally, the gearbox 1314 includes a worm gear 1315 and a worm wheel 1316. The output shaft of the drive motor 1313 is connected to the worm gear 1315. One end of the worm gear 1315 away from the drive member meshes with the worm wheel 1316. The worm wheel 1316 is also connected to the first rotating shaft 1323.

[0076] In this embodiment, the output shaft of the drive motor 1313 is connected to the worm gear 1315. When the drive motor 1313 is turned on, it drives the worm gear 1315 to rotate around its own axis. The end of the worm gear 1315 facing away from the drive component meshes with the worm wheel 1316, thereby pushing the worm wheel 1316 to rotate around its own axis. Furthermore, the worm wheel 1316 is also connected to the first rotating shaft 1323, thereby driving the first rotating shaft 1323 and the swing arm assembly 132 to rotate, and ultimately realizing the movement of the towing mechanism 120 relative to the base station body 110. The worm gear 1315 has helical teeth with a small number of teeth, while the worm wheel 1316 has a large number of teeth. For each rotation of the worm gear 1315, it only rotates by the angle corresponding to a few teeth, thus making the rotational speed of the worm wheel 1316 less than that of the worm gear 1315, thereby achieving a deceleration effect.

[0077] In some embodiments, the towing mechanism 120 is configured with a receiving cavity 124 for accommodating a pool cleaning robot. One end of the receiving cavity 124 is provided with an opening 125 for the pool cleaning robot to enter the receiving cavity 124. A movable baffle 126 for opening or closing the opening 125 is movably provided at the opening 125.

[0078] Understandably, the opening 125 is located at the free end 122 of the towing mechanism 120.

[0079] In this embodiment, a movable baffle 126 for opening or closing the opening 125 of the receiving cavity 124 is movably provided. When the movable baffle 126 is open relative to the opening 125, it facilitates the water tank cleaning robot to enter the receiving cavity 124 from the water tank, or to enter the water tank from the receiving cavity 124. When the movable baffle 126 is closed relative to the opening 125 and the water tank cleaning robot is located in the receiving cavity 124, the movable baffle 126 can prevent the water tank cleaning robot from leaving the receiving cavity 124, so that the water tank cleaning robot is stably mounted on the towing mechanism 120. The fixing member cooperates with the movable baffle 126 to make the towing mechanism 120 stably mounted on the base station body 110, and the water tank cleaning robot stably mounted on the towing mechanism 120, making it convenient for users to take the water tank cleaning robot out of the water tank or place the water tank cleaning robot in the water, thus improving the usability of the water-free base station 100.

[0080] Optionally, the base station body 110 also has an internal waterproof chamber 112, which is used to house the drive unit 131 to prevent the drive unit 131 from being damaged by water immersion, thereby extending the service life of the water-free base station 100.

[0081] Optionally, the base station body 110 further includes a sealing member 114, the waterproof chamber 112 has a through hole, the first rotating shaft 1323 passes through the through hole and is connected to the drive unit 131, and the sealing member 114 surrounds the outer periphery of the first rotating shaft 1323 and seals the through hole to seal the waterproof chamber 112.

[0082] Optionally, the base station body 110 also has a weight-adding component 113, which is located inside the base station body 110 and spaced apart from the waterproof chamber 112.

[0083] In this embodiment, the weight-adding component 113 can increase the weight of the water-removing base station 100, so that the water-removing base station 100 can be stably set up on the side of the pool. When the towing mechanism 120 switches between the retracted position and the extended position, even if the towing mechanism 120 carries the pool cleaning robot and at least partially extends below the liquid surface, it can prevent the water-removing base station 100 from tipping over and falling into the pool. The water-removing base station 100 has good performance.

[0084] Optionally, the weight-adding component 113 can be, but is not limited to, a water tank. When the water tank is filled with water, the weight of the base station body 110 can be increased, improving the stability of the water-free base station 100 located beside the pool. When the water-free base station 100 needs to be moved, the water in the tank can be drained to reduce the weight of the water-free base station 100, making it easier for users to move or transport.

[0085] Optionally, the base station body 110 also includes an anti-slip pad (not shown in the figure). The anti-slip pad is disposed at the bottom of the base station body 110. On the one hand, it can increase the friction between the base station body 110 and the edge of the pool, thereby improving the stability of the base station 100 placed on the edge of the pool. On the other hand, it can solve the problem of uneven contact surfaces between the base station body 110 and the edge of the pool, so that the base station 100 can be stably placed on the edge of the pool.

[0086] Optionally, in some embodiments, the number of anti-slip pads is four, and the four anti-slip pads are arranged around the outer periphery of the base station body 110.

[0087] Optionally, the water-free base station 100 further includes a liquid level sensor (not shown in the figure), which is used to detect whether the towing mechanism 120 is submerged in water, so as to detect the relative position of the towing mechanism 120 and the base station body 110.
