[0004] This disclosure relates to the field of clean technology, and more particularly to a base station. Background Technology

[0005] When existing pool robots perform cleaning tasks in the water, they need to be cleaned and emptied in a timely manner when the filter box inside the pool robot is full of debris, or when the amount of debris in the filter box reaches the budgeted amount.

[0006] Users typically retrieve the pool robot manually from the pool, remove the filter box inside, and then empty the contents. During this process, some debris often remains on the inner wall of the filter box, requiring manual cleaning and resulting in low cleaning efficiency.

[0007] In addition, in the existing technology, when the pool robot's battery is low and it needs to be charged, the user needs to manually move the pool robot to the charging dock for charging, which is time-consuming and laborious. Summary of the Invention

Detailed Implementation

[0012] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, so as to provide a thorough understanding of the embodiments of this disclosure. However, those skilled in the art will understand that this disclosure may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this disclosure with unnecessary detail.

[0013] like Figure 1 and Figure 2 As shown, this disclosure provides a cleaning system. The cleaning system includes a pool robot 1000 and a base station 2000, wherein the base station is used at least to clean the first filter box 1051 of the pool robot, so that the waste in the first filter box is transferred from the pool robot or temporarily stored in the base station.

[0014] The pool robot 1000 is used to perform cleaning, disinfection, and rescue tasks in a target area. The target area can be any water-containing area where the pool robot 1000 can move. For example, the target area can include, but is not limited to, swimming pools, water tanks, oil wells, sewers, etc. The following description uses a swimming pool (or water tank) as an example. For a swimming pool, the pool includes at least a bottom and pool walls.

[0015] like Figure 3 , Figure 5 , Figure 6 , Figure 9 and Figure 11As shown, the base station 2000 includes a base station body 20001, at least one first nozzle 2173, a second filter box 21102, and a charging assembly 2090. The base station body has a resting surface 200018, including a first resting position and a second resting position, for a swimming pool robot to rest on the base station. The first nozzle is disposed on the base station body and is used at least to spray liquid onto the first filter box of the swimming pool robot to clean the first filter box. The second filter box 21102 is disposed on the base station body and is used at least to receive waste from the first filter box. The charging assembly 2900 is disposed on the base station body 20001. When the swimming pool robot is resting at the first resting position, the first nozzle sprays liquid onto the first filter box, and the second filter box receives waste from the first filter box; when the swimming pool robot is resting at the second resting position, the charging assembly charges the swimming pool robot.

[0016] For the base station body 20001, in some embodiments, the base station body is used for docking of the pool robot to support the pool robot. For example, in some embodiments, the pool robot automatically walks from the pool to the base station body to dock; or, in other embodiments, the user manually moves the pool robot to the base station body to dock. For example, the base station body has a resting surface 200018 for the pool robot to dock; or, the base station body has at least a cleaning position, whereby when the pool robot docks in the cleaning position, the first nozzle of the second cleaning component (mentioned below) cleans the first filter box by spraying liquid onto the first filter box of the pool robot.

[0017] It should be noted that the resting surface for the pool robot to stop and move can be located on the top of the base station body, wherein, referring to Figure 4 As shown, the stopping surface 200018 has a first berth and a second berth. The first berth is configured to perform cleaning operations on the pool robot, and the second berth is configured to perform charging operations on the pool robot. In this embodiment, the positions of the first and second berths are not specifically limited. For example, the first berth can be located near the front end of the base station 2000, and the second berth can be located near the rear end of the base station 2000. Here, the front end and rear end of the base station 2000 refer to the direction along the front side to the rear side of the base station 2000. For another example, the first berth can be located near the rear end of the base station 2000, and the second berth can be located near the front end of the base station 2000. It is sufficient to ensure that the first berth is close to the first nozzle. That is, the first berth is closer to the first nozzle than the second berth. This design ensures that the pool robot's cleaning operation at the first berth does not affect the corresponding charging function. Specifically, as... Figure 4As shown, the first parking space is a cleaning position 7001 with cleaning function, and the second parking space is a charging position 7000 with charging function.

[0018] The dwelling surface 200018 is divided into at least two areas with different functions, namely the first berth and the second berth, which can realize the parallel or sequential operation of cleaning and charging of the pool robot. That is, the first berth is dedicated to cleaning the pool robot, and the second berth is dedicated to charging the pool robot.

[0019] In some embodiments, the first and second parking positions are at least partially offset. For example, using a plane parallel to the horizontal plane as the projection plane, the projections of the first and second parking positions on this plane do not overlap. This design allows the cleaning and charging functions to be completely separated spatially, avoiding interference between the functions. Alternatively, using a plane parallel to the horizontal plane as the projection plane, the projections of the first and second parking positions on this plane at least partially overlap. This design can further reduce the footprint of the base station, making it more compact. Of course, in some embodiments, the first and second parking positions can also completely overlap, i.e., the first and second parking positions are at the same location.

[0020] In some embodiments, the base station body further includes: a third receiving cavity 2054 and at least one fourth opening 2055. The fourth opening communicates with the third receiving cavity. At least a portion of the second filter box is disposed within the third receiving cavity. The fourth opening allows debris from the first filter box to pass through and enter the second filter box. The fourth opening is located within the first parking position.

[0021] Specifically, the base station body is provided with a third receiving cavity 2054, and the second filter box 21102 is removably installed in the third receiving cavity, at least for receiving waste from the first filter box. The top of the third receiving cavity 2054 is provided with at least one fourth opening 2055 communicating with the third receiving cavity. The opening is located in the area of ​​the first parking position, and the fourth opening is used for waste in the first filter box to pass through to enter the second filter box.

[0022] For the first nozzle, such as Figures 3 to 9 As shown, the first nozzle can be installed on the base station body. When the pool robot stops on the base station body, the first nozzle sprays liquid into the first filter box to rinse away the debris inside the first filter box and the debris adhering to the walls of the first filter box, thereby cleaning the debris inside the first filter box. During the cleaning process of the debris inside the first filter box, no manual intervention from the user is required, achieving automatic cleaning of the first filter box, improving cleaning efficiency and effectiveness, and enhancing the user experience.

[0023] The first nozzle 2173 effectively cleans the internal walls (including the top, side, and bottom walls) of the first filter box 1051 by spraying water or a water stream mixed with cleaning solution into the first filter box 1051. Specifically, high-pressure water jets can thoroughly break up and wash away algae, leaf fragments, and other dirt adhering to the walls of the first filter box. Alternatively, liquid sprays (such as clean water or cleaning solution) can be used to directionally rinse the first filter box, dissolving or washing away dirt attached to the filter screen and restoring filtration performance. This mechanized, precise spraying ensures the cleaning effect of the first filter box, guaranteeing that the pool robot is in optimal condition every time it starts working, while reducing the frequency and difficulty of manual maintenance by the user. Specifically, when the pool robot is stationary in the first parking position, the first nozzle sprays liquid into the first filter box for cleaning, while the second filter box receives debris from inside the first filter box.

[0024] For the charging component 2090, such as Figures 3 to 9 As shown, the charging component 2090 is mounted on the base station body, with at least a portion of the charging component 2090 protruding from the dwell surface 200018 for charging the pool robot. Specifically, the charging component 2090 can be positioned within the second berth. When the pool robot completes its cleaning task or runs out of power, it can automatically return to the second berth for charging, thus providing a continuous energy source for the pool robot and ensuring its fully automated operation. Furthermore, the use of the charging component 2090 allows the pool robot to directly return to the base station to replenish its power after completing a cleaning task, eliminating the need for an additional charger and providing energy security for continuous operation.

[0025] In some embodiments, when the first nozzle 2173 remains stationary relative to the base station body 20001; if the charging position 7000 and the cleaning position 7001 are the same position, after the first filter box is cleaned, since the first nozzle remains inserted into the first body, if the user lifts or moves the pool robot in the vertical direction or the height direction of the pool robot at this time, it will cause the first nozzle 2173 and the pool robot to collide, which may easily damage the first nozzle 2173 and the pool robot.

[0026] Therefore, in some embodiments, if the first nozzle 2173 remains stationary relative to the base station body 20001, such as Figure 4As shown, cleaning position 7001 and charging position 7000 are different positions. After the first filter box is cleaned, the pool robot will automatically walk from the cleaning position to the charging position. During the movement of the pool robot, the first nozzle passively and gradually retracts from the pool robot. When the pool robot reaches the charging position, the first nozzle is already outside the pool robot. When the pool robot stops at the charging position, regardless of whether the pool robot is charging or not, if the user lifts the pool robot at this time, the first nozzle and the pool robot will not collide, thus protecting both the first nozzle and the pool robot. Conversely, when the pool robot automatically moves from the charging position 7000 towards the cleaning position 7001, although the first nozzle 2173 does not move during this movement, the robot's movement causes it to gradually extend into the first filter box 1051 or the first gap. When the pool robot reaches the cleaning position 7001, the first nozzle 2173 is either already or just inside the first filter box 1051 or the first gap between the first body and the first filter box, allowing it to spray liquid to clean the first filter box 1051. In this embodiment, if the user manually places the pool robot on the base station, the user needs to place it in a non-cleaning position to avoid collision between the first nozzle and the pool robot. For example, the user can manually place the pool robot in the charging position.

[0027] In other embodiments, if the first nozzle is movable relative to the base station body, for example, by rotating or extending relative to the base station body, the first nozzle 2173 has a first position (i.e., a retracted position) and a second position (i.e., an extended position), and the first nozzle 2173 can switch between the first position and the second position. When the pool robot stops at the cleaning position 7001, the first nozzle 2173 switches from the first position to the second position to extend into the first body of the pool robot through the fourth inlet 1016. After the first nozzle sprays liquid to clean the first filter box, the first nozzle switches from the second position to the first position, and the first nozzle exits the pool robot. The movement of the first nozzle does not interfere with the movement of the pool robot. Therefore, when the first nozzle has a first position and a second position, the charging position and the cleaning position can be the same position, or the charging position and the cleaning position can be different positions. The second water inlet 1032 can serve as the fourth inlet, or the pick-up / drop-off port 1017 can serve as the fourth inlet.

[0028] In some embodiments, in order to discharge the waste from the first filter box, such as Figure 1 , Figure 2As shown, the first filter box includes a first frame 1053, a third opening 10531, and a first bottom cover 1054. The third opening is at least partially located on the bottom of the first frame, and the first bottom cover 1054 is movably disposed on the first frame for opening or closing the third opening. The first bottom cover 1054 has a locked state and an unlocked state. When the first bottom cover is in the locked state, it is locked to the first frame 1053, keeping the third opening 10531 closed. When the first bottom cover is in the unlocked state, it can move relative to the first frame to open or close the third opening.

[0029] In some embodiments, such as Figures 23 to 25 As shown, the pool robot also includes a locking mechanism 1080, which is used to lock the first bottom cover onto the first frame so that the first bottom cover remains closed at the third opening; correspondingly, the pool robot or base station body is provided with an unlocking mechanism, which is used to release the locking mechanism 1080 from locking the first bottom cover.

[0030] In some embodiments, such as Figures 23 to 25 As shown, the locking mechanism includes a first limiting hole 10801, a first locking member 10802, and a fourth elastic member 10803. The first limiting hole 10801 is provided on the first frame, and the first locking member is telescopically or slidably provided on the first bottom cover. The first locking member has a first limiting end 108021 and a first mounting end 108022. The fourth elastic member is a compression spring, with one end of the fourth elastic member provided on the first mounting end of the first locking member and the other end provided on the first bottom cover. The compression spring applies a biasing force to the first locking member in the direction of the first limiting hole, causing the first limiting end of the first locking member to tend to extend out of the first bottom cover and into the first limiting hole, thereby locking the first bottom cover on the first frame and keeping the first bottom cover closed at the third opening. Correspondingly, the unlocking mechanism is used to drive the first locking member to retract and move out of the first limiting hole.

[0031] In some embodiments, such as Figures 21 to 25 And refer to Figure 10 As shown, the unlocking mechanism includes a first motor 70035 and an unlocking component 70031. The first motor is mounted on the base station body, and the unlocking component is at least partially mounted on the base station body. The first motor drives the unlocking component to move, thereby driving the locking mechanism to move and release the locking mechanism from locking the first bottom cover of the first filter box and the first frame of the first filter box, so that the first bottom cover moves relative to the first frame to open or close the third opening.

[0032] In some embodiments, the unlocking component includes at least one first unlocking member 70037. A first motor drives the first unlocking member to perform a lifting movement. When the first unlocking member rises, it drives the locking mechanism to perform a retracting movement, thereby releasing the locking mechanism from locking the first bottom cover. The first unlocking member is movably mounted on the base station body near or adjacent to the fourth opening.

[0033] Furthermore, in some embodiments, the unlocking assembly further includes at least one second unlocking member 70033 and a fifth elastic member 70034, with the second unlocking member at least partially disposed within the pool robot. The pool robot also includes a third clearance opening 1001j, disposed on the bottom of the first main body to expose the force-bearing end of the second unlocking member to the outside. A first motor drives the first unlocking member to move upward, and the first unlocking member pushes the force-bearing end of the second unlocking member to drive the second unlocking member to rotate forward, causing the pushing end of the second unlocking member to rotate through the connecting hole 700331 into the first limiting hole, thereby pushing the first telescopic member to retract, and then the first telescopic member to exit the first limiting hole. The biasing force generated by the fifth elastic member tends to keep the pushing end of the second unlocking member outside the first limiting hole. After the locking mechanism is unlocked, when the first motor drives the first unlocking member to move downward, the first unlocking member removes the force applied to the force-bearing end of the second unlocking member. Under the action of the fifth elastic member, the second unlocking member rotates in the opposite direction to exit the first limiting hole, and the pushing end of the second unlocking member returns to the outside of the first limiting hole. The connecting hole is located in the first receiving cavity, for example, in the first dust chamber 1052. One end of the fifth elastic member abuts against at least a portion of the second unlocking member, and the other end abuts against the outer wall of the first dust chamber. In this embodiment, the fifth elastic member can be a torsion spring or a compression spring; alternatively, it can also be a tension spring.

[0034] like Figure 10 As shown, the base station also includes at least one sliding seat 70038, which is disposed on the resting surface and adjacent to or near the fourth opening. The sliding seat has at least one guide hole 700381, and the first unlocking member is slidably disposed in the guide hole. A first motor drives at least a portion of the first unlocking member to extend upward out of the guide hole to push the force-receiving end. When the first motor removes its push on the first unlocking member, the first unlocking member descends under its own gravity to return to its initial position.

[0035] In some embodiments, the slide protrudes from the resting surface. In the initial position, the top of the first unlocking member is approximately flush with or slightly above the top surface of the slide. This arrangement shortens the upward travel of the first unlocking member and prevents it from obstructing or colliding with the bottom of the pool robot when not unlocked. In some embodiments, the top of the first unlocking member may also be lower than the top surface of the slide.

[0036] In other embodiments, such as Figure 1 , Figure 2 , Figure 21 and Figure 22 As shown, the unlocking mechanism also includes at least one first transmission assembly, and the first motor and the first unlocking member are connected through the transmission assembly. For example, the first transmission assembly includes at least one first transmission member, which has at least one eccentric portion. For example, the transmission member is a cam 70039, which has at least one second protrusion 70040. The second protrusion serves as the eccentric portion. The first motor drives the cam to rotate in the forward direction. When the second protrusion abuts against the first unlocking member, the second protrusion pushes the first unlocking member to move upward, thereby causing the first unlocking member to push the first telescopic member to move or the second unlocking member to rotate, ultimately causing the first telescopic member to retract and exit the first limiting hole. When the first motor drives the cam to rotate in the reverse direction, after the second protrusion separates from the first unlocking member, the first unlocking member moves downward. One of the forward and reverse directions is clockwise, and the other is counterclockwise.

[0037] In some embodiments, since the waste and liquid in the first filter box enter the second filter box through the third opening and the fourth opening, the waste in the second filter box tends to accumulate at or below the fourth opening (e.g., the waste accumulates in a small hill). The waste accumulated at the fourth opening makes it difficult for the waste in the first filter box to fall into the second filter box.

[0038] Therefore, in some embodiments, the base station further includes at least one lever mechanism 7006. The lever mechanism is disposed on the base station body and is at least partially located within the second filter box. At least a portion of the lever mechanism moves reciprocally or oscillates to agitate the accumulated debris within the second filter box, causing the accumulated debris to spread out. By agitating the debris with the lever mechanism, the debris is evenly dispersed within the cavity of the second filter box, improving the space utilization within the second filter box, preventing debris from accumulating below the fourth opening, and ensuring that debris from the first filter box falls smoothly into the second filter box.

[0039] In some embodiments, the lever mechanism includes a third motor 70064 and a lever 70062. The third motor is mounted on the base station body, and at least a portion of the lever is located within the second filter box 21102. The third motor drives the lever to reciprocate or move reciprocally within the second filter box to dislodge debris. In some embodiments, at least a portion of the lever is located directly below at least a portion of the fourth opening.

[0040] In some embodiments, when the base station includes the aforementioned first motor and unlocking component, in this embodiment, the third motor is the first motor. That is, the third motor used to drive the lever movement and the first motor used to drive the first unlocking component movement are the same motor. The third motor drives the lever to swing back and forth or move back and forth, and can also drive the unlocking component to move, so as to drive the locking mechanism to release the lock on the first bottom cover.

[0041] In some embodiments, the lever mechanism further includes at least one second transmission component, with the lever connected to the transmission component. A third motor drives the transmission component to rotate, causing the lever to reciprocate, switching the lever between an initial position (i.e., the fifth position) and an unlocked position (i.e., the fourth position). When the lever is in the initial position, the transmission component is separated from the unlocking component; when the lever is in the unlocked position, the transmission component drives the unlocking component to move upward, thereby driving the locking mechanism to move. In this embodiment, the aforementioned first and second transmission components are also the same transmission component.

[0042] Correspondingly, in some embodiments, the second transmission component includes at least a cam 70039, which has at least one second protrusion 70040 (i.e., an eccentric portion). In the initial position, the eccentric portion is separated from the unlocking component; in the unlocked position, the eccentric portion abuts against the unlocking component, and the eccentric portion pushes the unlocking component to move upward. Specifically, when the lever is in the fourth position, the second protrusion pushes the first unlocking member to move upward, so that the first locking member disengages from the first limiting hole, unlocking the lock on the first bottom cover. When the lever is in the fifth position, the second protrusion disengages from the first unlocking member, and the second protrusion does not push the first unlocking member to move upward. After the first bottom cover is unlocked, and the first bottom cover opens the third opening, the first motor drives the lever to swing back and forth between the fifth and fourth positions to agitate the debris in the second filter box.

[0043] When the first bottom cover is rotatably mounted on the first frame, in some embodiments, the first bottom cover rotates under its own weight; or, under the combined weight of the first bottom cover and the weight of the waste and liquid inside the first filter box, to open the third opening. Correspondingly, in this embodiment, the base station also includes a closing mechanism mounted on the base station body. The closing mechanism drives the first bottom cover of the first filter box of the pool robot to rotate toward the third opening, thereby closing the third opening. Alternatively, the closing mechanism may also be mounted on the pool robot.

[0044] In some embodiments, such as Figure 7 , Figure 9 , Figure 26 As shown, the closing mechanism includes at least one first closing mechanism 7004, which drives the first bottom cover to rotate via a motor, so that the first bottom cover closes the third opening.

[0045] Specifically, in some embodiments, the first closing mechanism includes a driving component and a pushing component. The driving component includes at least a driving member, and the pushing component performs a telescopic movement under the drive of the driving member to switch between an extended state and a retracted state. In the retracted state, the pushing component avoids at least a portion of the first bottom cover extending into the fourth opening; in the extended state, at least a portion of the pushing component extends into the fourth opening to push the first bottom cover to rotate towards the third opening. The reciprocating swing or reciprocating movement of the lever avoids the telescopic movement of the pushing component. The two do not interfere with each other, ensuring that the trash agitation and the closing of the first bottom cover can occur simultaneously.

[0046] During the cleaning process of the first filter box by spraying liquid from the first nozzle, the actuating component is in a retracted state to avoid the first bottom cover. After the liquid sprayed by the first nozzle has cleaned the first filter box, the actuating component switches from the retracted state to the extended state to push the first bottom cover to rotate toward the third opening, thereby closing the third opening. After the first bottom cover closes the third opening, the actuating component switches from the extended state back to the retracted state. For example, the driving component can be a sixth motor 70042 or a cylinder.

[0047] For example, in some embodiments, such as Figure 1 , Figure 2 , Figure 9 and Figure 26 As shown, the pushing assembly is a push rod assembly, which includes at least one push rod 70041. The push rod includes a third mounting portion 700411 and a pushing portion 700412. The third mounting portion is driven and connected to a sixth motor, and the pushing portion is used to push the first bottom cover to rotate toward the third opening. The sixth motor drives the push rod to extend, causing the pushing portion to abut against the first bottom cover, thereby pushing the first bottom cover to rotate toward the third opening and closing the third opening. Specifically, in some embodiments, under the drive of the motor, the push rod performs an inclined extension movement, i.e., the push rod has motion components in both the horizontal and vertical directions. In other embodiments, under the drive of the motor, the push rod extends approximately in the vertical direction. Alternatively, in other embodiments, under the drive of the motor, the push rod extends approximately in the horizontal direction to push the first bottom cover to rotate.

[0048] In some embodiments, the pushing component is disposed on the base station body and located near, around, or on the periphery of the fourth opening, so as to shorten the distance between the pushing component and the fourth opening, so that when the pushing component extends, it can promptly push the first bottom cover to rotate toward the third opening. For example, at least a portion of the pushing component is located inside the base station body and on one side of the fourth opening.

[0049] In some embodiments, such as Figure 9As shown, the base station body also includes a sixth receiving cavity 2020, at least a portion of which is disposed outside the fourth opening (i.e., the fourth opening is a contamination inlet channel), as shown in the figure. Figure 10 As shown, the sixth receiving cavity and the fourth opening are connected through at least one first connecting port 70043. At least a portion of the pushing component is disposed within the sixth receiving cavity. When the pushing component switches from a retracted state to an extended state, at least a portion of the pushing component extends from the sixth receiving cavity to the fourth opening through the first connecting port to push the first bottom cover to rotate toward the third opening; conversely, at least a portion of the pushing component retracts from the fourth opening into the sixth receiving cavity through the first connecting port, causing the pushing component to return to the retracted state.

[0050] In other embodiments, such as Figures 7 to 12 As shown, the closing mechanism includes at least one second closing mechanism 7005. The aforementioned first closing mechanism drives a push component to extend and retract via a motor or cylinder, thereby pushing the first bottom cover to rotate toward the third opening. During the closing of the first bottom cover, the pool robot remains stationary on the base station body or stops at a cleaning position. In this embodiment, the second closing mechanism does not have a drive component. Instead, it relies on the pool robot walking on the base station body. After the first bottom cover comes into contact with the second closing mechanism, the first bottom cover is passively rotated toward the third opening under the contact force of the second closing mechanism to close the third opening. For example, in some embodiments, the second closing mechanism is located on the base station body and is at least partially exposed outside the resting surface. For example, the resting surface is the upper surface of the base station body, that is, at least part of the second closing mechanism is exposed on the upper surface.

[0051] For example, in some embodiments, the second closing mechanism includes at least one second protrusion component 70051, which protrudes from the resting surface of the base station body and is located between the charging component and the fourth opening. During the movement of the pool robot from the first berth to the second berth on the resting surface, the first bottom cover slides against the second protrusion component 70051, forcing the first bottom cover to passively rotate towards the third opening to close it.

[0052] Specifically, in some embodiments, after the first filter box is cleaned by the first nozzle, the pool robot moves from the first docking position to the second docking position on the resting surface, causing the first bottom cover to slide against the second protruding component. The second protruding component forces the first bottom cover to passively rotate towards the third opening to close the third opening. In some embodiments, the second protruding component is rotatably disposed on the base station body, so that during the movement of the pool robot, the second protruding component and the first bottom cover form rolling friction, reducing wear on the first bottom cover. Alternatively, in other embodiments, the second protruding component protrudes and is fixed to the base station body.

[0053] The highest point of the second protrusion component 70051 can be higher than the highest point of the second upper shell 20001a, thereby ensuring that the second protrusion component can abut against the first bottom cover during the movement of the pool robot, causing the first bottom cover to rotate and close the third opening.

[0054] In one embodiment, such as Figures 8 to 10 As shown, the second upper shell is provided with a mounting base 200031, and the mounting base has a first mounting hole 200032. The first mounting hole 200032 corresponds to the second mounting hole 700511 on the second protruding component, and a mounting rod passes through the first mounting hole and the second mounting hole to movably fix the second protruding component on the resting surface. The second upper shell is also provided with a clearance position 200033 to provide sufficient rotation space for the second protruding component and avoid obstructing its rotation. The highest point of the second protruding component can be higher than the highest point of the mounting base to ensure that the second protruding component can abut against the first bottom cover during the movement of the pool robot, causing the first bottom cover to rotate and close the third opening. The second protruding component may include, but is not limited to, a roller, which is rotatably mounted on the mounting base via the mounting rod.

[0055] In some embodiments, the second closing mechanism is located near the fourth opening and protrudes from the base station body. For example, the second protruding component is located at the edge of the fourth opening near the charging component, so that when the pool robot begins to move, the second protruding component immediately abuts against the first bottom cover, causing the first bottom cover to rotate and close the third opening, preventing the third opening from remaining open and contaminating the resting surface during movement. Alternatively, the second protruding component is located between the fourth opening and the charging component to ensure that the third opening is already closed when the first bottom cover reaches the charging position.

[0056] In some embodiments, the base station may be provided with only a first shut-off mechanism; or only a second shut-off mechanism; or, in other embodiments, the base station may be provided with both a first shut-off mechanism and a second shut-off mechanism.

[0057] In some embodiments, such as Figures 3 to 12 As shown, the charging assembly includes at least a charging element 2091 disposed on the resting surface. The pool robot includes a charging receiver 1020 disposed on the bottom of the first main body. The charging element and the charging receiver charge the pool robot by contact, or the charging element and the charging receiver are wirelessly charged.

[0058] The charging component has at least one working state protruding from the dwelling surface for charging the pool robot. The charging component and the fourth opening 2055 are staggered on the dwelling surface. The charging component is located within the second berthing position. The staggered distribution of the charging component and the fourth opening in the horizontal projection achieves physical isolation of the functional areas, ensuring safety.

[0059] In one embodiment, the charging device includes a first charging pad, and correspondingly, the charging receiver includes a second charging pad. The first and second charging pads are brought into contact to achieve charging. Alternatively, in other embodiments, the charging device includes a transmitting coil, and correspondingly, the charging receiver includes a receiving coil. The transmitting coil and the receiving coil are brought into contact or close together to achieve wireless charging. The following description uses the example of a charging device including a first charging pad.

[0060] In some embodiments, the charging component includes two first charging pads 20915, each first charging pad having an upwardly protruding charging bump 20913, one charging bump being a positive electrode and the other a negative electrode. The charging receiver includes two second charging pads 10201, one second charging pad being a positive electrode and the other a negative electrode; the charging bump and the second charging pad form a point-to-surface contact to achieve charging. The presence of one charging bump on each first charging pad is primarily to prevent electrical sparks. If three or more charging bumps are provided, and some of them fail to contact the second charging pad, at least one of the remaining charging bumps will generate electrical sparks due to excessive current. A single charging bump either contacts the second charging pad for charging or does not, thus preventing charging but avoiding electrical sparks.

[0061] In the aforementioned embodiments, since the pool robot carries liquid after the user lifts it out of the pool, the liquid easily forms a water film on the plane of the second charging plate. The water film can easily cause the second charging plate, which serves as the positive electrode, to be electrolyzed, affecting the charging performance.

[0062] Therefore, in some embodiments, the charging device includes two first charging plates, one of which is a positive electrode and the other is a negative electrode. The charging receiver includes two second charging plates, each of which has a downwardly protruding charging bump; one charging bump serves as the positive electrode, and the other as the negative electrode; a point-to-surface contact is formed between the charging bump and the first charging plate to achieve charging. When the user lifts the pool robot out of the pool, the pool robot carries liquid. Because the charging bump is located on the second charging plate, the liquid is less likely to form a water film at the bump, thus the bump, acting as the positive electrode, is less prone to electrolysis, improving its charging performance.

[0063] In some embodiments, the area of ​​the second charging pad is larger than the area of ​​the first charging pad. With this configuration, even if there is a deviation in the center position of the first and second charging pads when they are aligned, the second charging pad can completely cover the first charging pad, thus ensuring charging efficiency. In other words, the area of ​​the second charging pad on the pool robot is larger than the area of ​​the first charging pad on the base station, forming a "small pad to large pad" coverage relationship (the projection of the first charging pad is located within the projection of the second charging pad). This greatly reduces the requirements for the docking accuracy of the pool robot, allows for a certain degree of positional deviation, and improves the fault tolerance and success rate of charging docking.

[0064] When the pool robot stops on the base station and is charged by the charging components on the base station, the second charging pad covers the first charging pad. That is, the first projection of the first charging pad on the vertical plane is located within the second projection of the second charging pad on the vertical plane to ensure stable power transmission.

[0065] In some embodiments, such as Figures 13 to 17 As shown, the charging assembly also includes a first base 2096, which is movably mounted on the base station body, and the charging component is mounted on the first base. Specifically, the first base is movably mounted on the mounting plate 200013, and the charging component is fixed on the first base. The first base can be directly or indirectly mounted on the mounting plate.

[0066] Furthermore, in some embodiments, the bottom of the first base is provided with at least one first support post 2092, and a first elastic member 2093 is sleeved on the first support post. The first elastic member is defined between the mounting plate and the first base. The elastic force of the first elastic member acts on the first base, so that the charging member and the charging receiver can be tightly abutted, ensuring the charging effect of the charging member on the charging receiver.

[0067] Because the charging component protrudes from the resting surface, the bottom of the pool robot may scrape against the charging component when it moves on the resting surface, potentially causing damage. Therefore, in some embodiments, the first base 2096 has a second mounting end 20961 and a second free end 20962 disposed opposite to each other, wherein the second mounting end is movably mounted on the base station body. Through the movement of the first base, the charging component has at least a working position and a avoidance position in the height direction of the base station body. In the working position, the charging component protrudes from the resting surface and is used to abut or approach the charging receiver on the bottom of the pool robot for charging the pool robot. In the avoidance position, the charging component avoids the bottom of the pool robot, preventing the bottom of the pool robot from scraping against the charging component when it moves on the resting surface, thus affecting the charging performance and ensuring the normal movement of the pool robot.

[0068] In some embodiments, the charging assembly further includes at least one second elastic element (not shown in the figure), which, by applying its elastic force to the first base body, tends to hold the charging component in the working position; under the action of an external driving force, the first base body moves to move the charging component downward, and the charging component switches from the working position to the avoidance position; after the driving force is removed, under the action of the elastic force of the second elastic element, the charging component resets from the avoidance position to the working position. That is, the charging component floats relative to the base station body to switch between the working position and the avoidance position.

[0069] For example, in some embodiments, the first base is rotatably connected to the base station body. The second elastic element is a torsion spring. The torsion spring is disposed on the second mounting end of the first base, and one end of the torsion spring is connected to the first base, for example, one end of the torsion spring is fixed to the bottom of the first base, and the other end is connected to the base station body. Under the elastic force generated by the torsion spring on the first base, the charging component can be held in the working position. When the first base is subjected to an external driving force to overcome the elastic force of the torsion spring, the first base rotates, causing the charging component to rotate from the working position to the avoidance position, thereby preventing the bottom of the pool robot from scraping against the charging component when the pool robot moves on the resting surface.

[0070] In other embodiments, the first base is telescopically mounted on the base station body along its height. The second elastic element is a tension spring or a compression spring. Under the action of the second elastic element, the charging component can extend from the avoidance position to the working position; after an external driving force overcomes the force of the second elastic element, the charging component can retract from the working position to the avoidance position. In some embodiments, the second elastic element is a compression spring, which is embedded in the first support column at the bottom of the first base, and the second elastic element is confined between the mounting plate and the first base.

[0071] In some embodiments, such as Figures 3 to 16 As shown, the charging assembly also includes at least one first protrusion component 2094, which is disposed on the first base. When the charging component is in the working position, the first protrusion component protrudes from the resting surface. A second elastic member applies an elastic force to the first base to keep the charging component in the working position. As the pool robot moves from the first docking position to the second docking position on the base station body, the first protrusion component abuts against the bottom of the pool robot before the charging component, forcing the first base to move and causing the charging component to switch from the working position to the avoidance position. When the pool robot moves to the second docking position, the bottom of the pool robot releases its contact with the first protrusion component, and the charging component, under the action of the second elastic member, returns from the avoidance position to the working position.

[0072] Specifically, in some embodiments, the bottom of the pool robot is further provided with a fourth groove 1021. When the pool robot moves to the second parking position, the first protruding component is embedded in the fourth groove 1021, the bottom of the pool robot releases the driving force on the first protruding component, and the charging component, under the action of the second elastic member, resets from the avoidance position to the working position, thereby allowing the charging of the pool robot to begin.

[0073] In some embodiments, the first protruding component is a support roller, which is rotatably mounted on the first base. The support roller is rotatably mounted on the base station body, so that when the pool robot comes into contact with the support roller, rolling friction is generated between the bottom of the pool robot and the support roller, reducing the friction between the bottom of the pool robot and the first protruding component and preventing the bottom of the pool robot from being scraped. The support roller is passively driven; during the movement of the pool robot, the pool robot drives the support roller to rotate. The support roller does not require a motor drive. Of course, the first protruding component can also be a protrusion fixed to the first base.

[0074] When the pool robot is in the second docking position, the support rollers are located within the fourth groove, and the charging component is in the working position. When the pool robot moves from the first docking position to the second docking position, the fourth groove is misaligned with the support rollers. The support rollers are then abutted by the bottom of the pool robot, causing the first base to move. Consequently, the charging component switches from the working position to the avoidance position. In other words, as long as the pool robot moves from the first docking position to the second docking position, the charging component remains in the avoidance position, and the bottom of the pool robot will not scratch the charging component.

[0075] In some embodiments, the fourth opening serves as an entry point for waste to enter the base station body. When the cleaning position and the charging position are the same location, the charging component is located between the first protruding component and the fourth opening; or, when the cleaning position and the charging position are different locations, the first protruding component is located between the charging component and the fourth opening.

[0076] Specifically, in some embodiments, such as Figure 4 As shown, when the cleaning position and the charging position on the base station body are in the same position, the charging component is located between the first protruding component and the fourth opening; or, the charging component is closer to the first nozzle than the first protruding component, so that the bottom of the pool robot can avoid scratching the charging component during the process of the pool robot automatically walking from the pool to the cleaning position with the help of the carrier.

[0077] Alternatively, in some embodiments, such as Figures 4 to 9As shown, when the cleaning position and the charging position on the base station body are different positions, the cleaning position is closer to the first nozzle than the charging position, and the first protruding component is located between the charging component and the fourth opening; or, the first protruding component is closer to the first nozzle than the charging component, so that the bottom of the pool robot avoids scratching the charging component during the process of the pool robot walking from the cleaning position to the charging position.

[0078] In some embodiments, the first base is rotatably mounted on the base station body, and the first protruding component is located between the charging component and the pivot (i.e., the second mounting end) of the first base; or, the charging component is located between the first protruding component and the pivot of the first base. Wherein, the first protruding component is located between the charging component and the second mounting end, allowing the charging component to move downwards a greater distance when the pool robot comes into contact with the first protruding component, resulting in a larger space between the charging component and the bottom of the pool robot, thus better preventing the charging component from being scratched by the bottom of the pool robot.

[0079] In some embodiments, the base station body is provided with at least one fourth clearance port 20002, and the charging component switches between a working position and a clearance position through the fourth clearance port. Specifically, the first base is at least partially disposed within the base station body and at least partially located at the fourth clearance port. The charging component is disposed on the first base and located at the fourth clearance port, such that the charging component switches between a working position and a clearance position through the fourth clearance port.

[0080] When the charging component is in the avoidance position, at least a portion of the charging component enters the base station body, causing the charging component to avoid the bottom of the pool robot; when the charging component is in the working position, at least a portion of the charging component can extend from the base station body through the fourth avoidance port onto the resting surface, and the charging component can come into contact with or approach the charging receiver at the bottom of the pool robot to charge the pool robot.

[0081] In some embodiments, the first housing may also be provided with a drainage hole 20914. For example, the drainage hole is located below the first protruding component. The drainage hole can drain incoming moisture and prevent moisture accumulation from affecting charging.

[0082] In some embodiments, such as Figure 9 , Figure 10 , Figures 12 to 14 As shown, the base station also includes a drying component 2800, which can provide ambient temperature air or hot air to at least dry the charging component, ensuring it is in a dry state; alternatively, the drying component can also be used to dry both the charging component and the charging receiver simultaneously. For example, when the charging receiver at the bottom of the pool robot docks with the charging component, the drying component can dry both the charging component and the charging receiver simultaneously.

[0083] In some embodiments, such as Figure 9As shown, the stopping surface includes a first segment 2000181 and a second segment 2000182. The first segment includes at least a portion of the first berth, and the second segment includes at least a portion of the second berth. The first segment is horizontal, and the second segment is either horizontal or sloping. Specifically, in some embodiments, at least a portion of the charging component is located on the second segment. When the pool robot stops on the first segment, a first nozzle sprays liquid to clean the first filter box; when the pool robot stops on the second segment, the charging component charges the pool robot. The second segment is directly or indirectly connected to the first segment.

[0084] Specifically, in one embodiment, such as Figure 9 As shown, the first segment is roughly horizontal. When the pool robot is stationary on the first segment, it is in a roughly horizontal position, which facilitates the first nozzle to extend horizontally into the first main body through the second inlet 1032 or to exit the pool robot; or, it facilitates the first nozzle to extend vertically into the second filter box through the pick-up and drop-off port 1017 or to exit the pool robot, thus avoiding collisions between the first nozzle and the pool robot when the first nozzle extends into or exits the pool robot.

[0085] Furthermore, in some embodiments, such as Figures 3 to 5 As shown, the second segment is roughly horizontal. When the pool robot is on the second segment, it is in a roughly horizontal position. For example, the first and second segments are roughly on the same horizontal plane, which facilitates the pool robot's movement on a horizontal surface to switch between cleaning and charging positions, and allows it to stop accurately in either position.

[0086] Alternatively, in other embodiments, such as Figure 9 As shown, the second section is a sloping section. When the pool robot is on the second section, it is in a tilted position. Because the second section is tilted, when the charging component is located on the second section, the liquid on the first and / or second sections can flow out from the base station body along the slope of the second section, thus preventing liquid from remaining on the second section and affecting the charging effect.

[0087] In some embodiments, such as Figure 8 and Figure 9 As shown, when the second segment is a sloping section, the base station also includes a support assembly 200023. The support assembly is disposed on the second segment and located on the side wall of the second segment away from the first segment. The support assembly is configured to provide support for a pool robot performing charging operations at the second berth.

[0088] The support assembly includes a support platform 2000231, which is integrally formed with or detachably connected to the base station body. The support platform 2000231 abuts against the rear part 10012 of the pool robot, preventing the pool robot from slipping off the inclined surface of the second section. The top of the support platform can be curved, meaning the part of the support platform that contacts the pool robot is curved, and the curvature of the curved part can be adapted to the contour of the pool robot's shell. This design increases the contact area between the support platform and the pool robot, improving the support effect, while also preventing the support platform from scratching the pool robot. For example, the support platform has a groove 20002311, with the opening of the groove located at the top of the support platform. The shape of the groove matches the shape of the main roller brush of the pool robot, and the width of the groove is greater than or equal to the width of the main roller brush.

[0089] Furthermore, in one embodiment, a flow guide port 2000232 is provided on the support platform. The flow guide port can penetrate the support platform. The flow guide port can drain the liquid flowing from the pool robot and the resting surface to the support assembly, avoiding liquid accumulation on the support assembly. Preferably, the flow guide port is located at the lowest point of the bottom of the groove, thereby facilitating the drainage of liquid on the resting surface.

[0090] In one embodiment, the support assembly further includes auxiliary support components. Multiple auxiliary support components are symmetrically arranged on both sides of the flow guide. The auxiliary support components are rotatably mounted on the support platform. For example, in one embodiment, the auxiliary support components can be rollers, omnidirectional balls, etc. When the pool robot stops on the second section, the auxiliary support components contact at least a portion of the pool robot's bottom shell 1001f, for example, the auxiliary support components contact the bottom shell 1001f between the walking mechanism 1071 and the main roller brush 1131. The auxiliary support components not only support the pool robot but also guide and position it. For example, when the rear of the pool robot is placed on the support platform, the auxiliary support components can guide the pool robot to rotate to the charging position; or when the pool robot walks from the first parking position to the second parking position, the auxiliary support components can guide the pool robot to walk to the support platform and stop. Furthermore, during the process of guiding the pool robot to the charging position, or during the process of the pool robot walking to the support platform and stopping, rolling friction can be formed between the portion of the auxiliary support component and the bottom shell, thereby reducing frictional loss.

[0091] In some embodiments, the dwelling surface 200018 is further provided with an anti-slip component, which is configured to provide guiding support and / or anti-slip support to the pool robot as it moves between the first and second dwelling positions. The anti-slip component can ensure the stability of the pool robot when moving between different functional areas and prevent slipping or deviating from the track.

[0092] Specifically, such as Figures 4 to 7As shown, the anti-slip assembly includes a first anti-slip assembly 7008 and a second anti-slip assembly 7009. Multiple first anti-slip assemblies 7008 are symmetrically arranged and positioned near the second docking position. Multiple second anti-slip assemblies 7009 are symmetrically arranged and positioned near the first docking position. The first and second anti-slip assemblies 7008 and 7009 have identical structures and are mirror-symmetrical, providing corresponding anti-slip support when the pool robot moves in both directions.

[0093] The pool robot also includes at least two walking mechanisms 1071, which are located on the bottom or side of the first main body. The walking mechanisms 1071 are used to drive the pool robot to walk on the pool bottom and pool walls. The walking mechanism 1071 may include at least two wheels with multiple protrusions. Alternatively, the walking mechanism 1071 may include at least two wheels and a track 117, which is wrapped around the outer periphery of the wheels and has multiple teeth 10711.

[0094] Both the first anti-slip component 7008 and the second anti-slip component 7009 are provided with multiple recesses, with the recesses on the first anti-slip component facing opposite directions to those on the second anti-slip component. During the process of the pool robot moving from the second docking position to the first docking position, the teeth 10711 of the walking mechanism 1071 engage with the recesses on the first anti-slip component 7008, applying a force towards the first docking position to the teeth of the walking mechanism 1071 through the recesses on the first anti-slip component 7008. When the walking mechanism 1071 partially moves to the first docking position, sliding friction is formed between the recesses on the second anti-slip component 7009 and the corresponding portion of the teeth on the walking mechanism 1071. Furthermore, during the process of the pool robot moving from the first parking position to the second parking position, the notch on the second anti-slip component 7009 engages with the teeth 10711 on the walking mechanism 1071. This allows the notch on the second anti-slip component 7009 to apply a force towards the second parking position to the teeth of the walking mechanism 1071. Additionally, when the walking mechanism 1071 partially moves to the second parking position, sliding friction is formed between the notch on the first anti-slip component 7008 and that portion of the teeth on the walking mechanism 1071. Based on this, the stability and directionality of the pool robot when moving between the two functional areas can be effectively ensured.

[0095] In one specific embodiment, the first anti-slip component 7008 is disposed on the top of the base station body 20001 and located on both sides of the charging component 2091. When the pool robot docks at the charging position, the bottom surface or teeth 10711 of its tracks (or wheels) will contact the first anti-slip component 7008. At this time, the first anti-slip component 7008 significantly increases the friction between the tracks and the top contact area of ​​the base station body 20001 by increasing the roughness of the contact surface and / or providing mechanical interlocking. Based on this, it can effectively prevent the pool robot from sliding due to gravity, slight ground vibration, or small displacement tendency caused by the operation of the device itself when docked, ensuring that the pool robot is stably docked at the charging position. When the pool robot moves from the charging position 7000 to the cleaning position 7001, the track rotates under the drive of the walking wheels and comes into dynamic contact with the first anti-slip component 7008. The friction provided by the first anti-slip component 7008 enhances the traction of the track on the relatively smooth top of the base station body 20001 (especially in the low adhesion area that may exist at the moment of startup).

[0096] Specifically, the first anti-slip component 7008 includes a plurality of first protrusions 70081 arranged in parallel. Each first protrusion 70081 includes a first end 70082 and a second end 70083. The first end and the second end are connected by a slope or a curved surface. It should be noted that a notch is formed between the second end 70083 of the first protrusion 70081 and the second end 70083 of the second protrusion 70081.

[0097] From the perspective of the pool robot's forward direction (i.e., moving from the charging position to the cleaning position), the first end is the starting point of the ramp, and the second end is the ending point of the ramp, with the second end positioned higher than the first end. Alternatively, from the perspective of the pool robot's backward direction (i.e., moving from the cleaning position to the charging position), the second end is the starting point of the ramp, and the first end is the ending point of the ramp, with the second end positioned higher than the first end. Therefore, when the pool robot stops at the charging position, if there is a tendency to slide backward (i.e., in the opposite direction of forward movement), the higher second end of the first protrusion will form an effective mechanical barrier, preventing the pool robot from sliding backward. When the pool robot moves from the charging position to the cleaning position, the wheels drive the tracks to rotate, and the teeth of the tracks contact the higher second end of the first protrusion (the ending point of the ramp). The second end applies a force towards the cleaning position to the teeth, and under the action of this force, the teeth / bottom surface of the tracks climb upward along the ramp or curved surface until the tracks completely disengage from the first protrusion. The smooth ramp or curved surface design helps the tracks smoothly "climb" over the first protrusion.

[0098] In one specific embodiment, the second anti-slip component 7009 is disposed on the top of the base station body and located on both sides of the first sewage inlet (i.e., the fourth opening 2055). When the pool robot stops at the cleaning position, the bottom surface or teeth of its tracks (or wheels) will contact the first anti-slip component. At this time, the first anti-slip component significantly increases the friction between the tracks and the contact area on the top of the base station body by increasing the roughness of the contact surface and / or providing mechanical interlocking. Based on this, it can effectively prevent the pool robot from sliding due to gravity, slight ground vibration, or small displacement tendency caused by the operation of the equipment itself when it is stopped, ensuring that the pool robot is stably stopped at the cleaning position. When the pool robot walks from the cleaning position to the charging position, the tracks rotate under the drive of the wheels and make dynamic contact with the second anti-slip component. The friction provided by the second anti-slip component enhances the traction of the tracks on the relatively smooth top of the base station body (especially in the low adhesion area that may exist at the moment of startup).

[0099] Specifically, the second anti-slip component includes a plurality of second protrusions 70091 arranged in parallel. Each second protrusion includes a third end 70092 and a fourth end 70093. The third end and the fourth end are connected by a slope or a curved surface. It should be noted that a notch is formed between the fourth end 70093 of the first second protrusion 70091 and the fourth end 70093 of the second second protrusion 70091.

[0100] From the perspective of the pool robot's backward movement (i.e., from the cleaning position to the charging position), the third end is the starting point of the ramp, and the fourth end is the ending point of the ramp, with the fourth end positioned higher than the third end. Alternatively, from the perspective of the pool robot's forward movement (i.e., from the charging position to the cleaning position), the fourth end is the starting point of the ramp, and the third end is the ending point of the ramp, with the fourth end positioned higher than the third end. Therefore, when the pool robot stops at the cleaning position, if there is a tendency to slide backward (i.e., in the opposite direction of the backward movement), the higher fourth end of the first tooth will form an effective mechanical barrier, preventing the pool robot from sliding backward. When the pool robot moves from the cleaning position to the charging position, the wheels drive the tracks to rotate, and the teeth of the tracks contact the higher fourth end of the second protrusion (the ending point of the ramp). The fourth end applies a force towards the charging position to the teeth, and under the action of this force, the teeth / bottom surface of the tracks climb upward along the ramp or curved surface until the tracks completely disengage from the second protrusion. The smooth ramp or curved surface design helps the tracks smoothly "climb" over the second protrusion.

[0101] In some embodiments, the base station body 20001 is provided with a first anti-slip component 7008 and a second anti-slip component 7009. The first anti-slip component is disposed on both sides of the charging component, and when the pool robot stops at the charging position, at least a portion of the track contacts the first anti-slip component; the second anti-slip component is disposed on both sides of the first waste inlet, and when the pool robot stops at the cleaning position, at least a portion of the track contacts the second anti-slip component. Alternatively, in some embodiments, the base station body 20001 is provided with the first anti-slip component 7008. Alternatively, in some embodiments, the base station body 20001 is provided with the second anti-slip component 7009.

[0102] In some embodiments, such as Figure 3 As shown, the base station also includes a carrier 2040, which is rotatably connected to the base station body 20001. For example, one end of the carrier is connected to the base station body, and the other end is adapted to extend into the pool, allowing the pool robot to automatically walk from the pool back to the charging or cleaning position on the base station body using the carrier. For example, the first end 2041 of the carrier is connected to the base station body, and the second end 2042 is adapted to extend into the pool. When the pool robot automatically walks from the pool to the cleaning position on the base station body using the carrier, the first nozzle sprays liquid to clean the first filter box; when the pool robot automatically walks from the pool to the charging position on the base station body using the carrier, the charging component charges the pool robot. In this embodiment, the cleaning position and the charging position on the base station can be the same position or different positions.

[0103] The base station disclosed in this application can be used on land, for example, by placing it on the bank of a pool or on the ground. In this case, the base station is in an air environment, and the pool robot can automatically get out of the pool and walk onto the base station. For example, the base station also includes a support component, one end of which is attached to the base station body, and the other end extending below the surface of the water in the pool, allowing the pool robot to walk from the pool to the support component and then back to the base station body. Alternatively, the pool robot can be manually carried onto the base station body by a user.

[0104] When the base station is used on shore or on the ground, the first filter box is in the air, and the first nozzle sprays water at least to the side and / or bottom of the first filter box to rinse the side and / or bottom of the first filter box, not only flushing the garbage inside the first filter box out of the first filter box, but also washing away the garbage attached to the side and / or bottom of the first filter box.

[0105] When the base station is placed on the shore or on the ground, the water source for cleaning the first filter box can be municipal water from the user's home. For example, water from a tap. Since municipal water is pumped to the user's tap, the base station may or may not need to have a first water pump. Alternatively, the water source for cleaning the first filter box can be other types of water, such as water from a pool or river. In this embodiment, the base station needs to include at least one first water pump, which draws water from the pool or river to the first nozzle, causing the nozzle to spray water.

[0106] The liquid filtered by the second filter can be discharged into the user's sewer or outdoor lawn; alternatively, it can be discharged into a pool for reuse. Furthermore, the base station also includes a second water pump, which is used to pump the liquid filtered by the second filter out of the base station to accelerate the discharge of the liquid from the base station.

[0107] The base station disclosed in this application can also be placed inside a pool or in a placement area connected to the pool. For example, the base station can be placed on a raised platform inside the pool. For example, the raised platform can be a sun deck or steps within the pool, wherein the sun deck and steps can be separated in the pool, or the sun deck can serve as a step surface of the steps. Alternatively, a recessed placement area can be provided on the pool bank, and the placement area can be connected to the pool through an opening in the pool wall, where the base station can be installed. Alternatively, the base station can be installed on the pool wall; or on the bottom of the pool; or it can be placed in other locations within the pool. When the base station is installed inside the pool or in a placement area, a pool robot can automatically walk back to the base station body from the pool; or, the pool robot can be manually carried to the base station body by a user.

[0108] The base station also includes a drainage channel for discharging the liquid filtered by the second filter box outside the base station; one end of the drainage channel connects to the third receiving cavity, and the other end serves as the final drain outlet. In scenarios where the base station is placed in a pool or placement area, when the pool robot is stationary on the base station body, if the final drain outlet is at least partially or completely below the first liquid level in the pool, the base station also includes at least one second water pump for pumping the liquid filtered by the second filter box out of the base station. If the final drain outlet is above the first liquid level in the pool, the base station may or may not have a second water pump.

[0109] If the base station is placed in a pool or within a designated area, when the pool robot is stationary on the base station, if the first liquid level in the pool is lower than or roughly level with the fourth opening of the base station, the first filter box is located above the fourth opening and is therefore in the air. Alternatively, if the first liquid level in the pool is lower than the bottom of the first filter box, the first filter box is also in the air. The first nozzle sprays liquid onto the first filter box to clean it. The cleaning effect of the first nozzle on the first filter box is roughly the same as if the base station were on land or ground. In other words, the first nozzle sprays water onto the first filter box located in the air to clean the debris inside and adhering to the inner wall of the first filter box.

[0110] The main body of the pool robot is provided with at least one first water outlet, and at least part of the first water outlet is located on the top of the main body. When the pool robot cleans the liquid in the pool, the liquid filtered by the first filter box is discharged out of the pool robot through the first water outlet.

[0111] In scenarios where the base station is placed in a pool or within a designated area, when the pool robot is stationary on the base station, if the first liquid level in the pool is between the bottom of the first filter box and the first outlet, at least a portion of the side of the first filter box is positioned below the first liquid level, creating a second liquid level within the first filter box. This second liquid level can be higher, lower, or equal to the first liquid level. For example, when the pool robot is stationary on the base station, before the first nozzle and second water pump are running, the first liquid level in the pool is between the bottom of the first filter box and the first outlet; or, when at least one of the first nozzle and second water pump is running, the first liquid level in the pool is between the bottom of the first filter box and the first outlet.

[0112] For example, for ease of description, the side portion of the first filter box located below the second liquid surface is referred to as the first side portion, and the side portion of the first filter box located above the second liquid surface is referred to as the second side portion. Since the first side portion is located below the second liquid surface and the second side portion is located above the second liquid surface, that is, the second side portion is in the air environment, when the first nozzle sprays water onto the first side portion and the second side portion, the first impact force of the water sprayed onto the first side portion is greatly reduced, while the second impact force of the water sprayed onto the second side portion is not reduced. The first impact force is less than the second impact force. Therefore, the water sprayed by the first nozzle can clean the garbage attached to the second side portion, but cannot clean the garbage attached to the first side portion.

[0113] Therefore, in order to clean the debris attached to the first side of the first filter box, in this embodiment, the liquid in the first filter box is continuously drawn into the second filter box by operating the aforementioned second water pump (e.g., turning it on or increasing the operating parameters). The liquid is then filtered by the second filter box, making the outflow of water from the first filter box greater than the flow rate of liquid sprayed from the first nozzle into the first filter box (i.e., the inflow of water into the first filter box); or the drainage volume of the second water pump per unit time is greater than the spray volume of the first nozzle per unit time, causing the second liquid level in the first filter box to drop. This keeps the side of the first filter box continuously exposed above the second liquid level, i.e., in the air environment, thereby reducing the proportion of the first side on the side of the first filter box. This allows the water flow sprayed by the first nozzle to clean the second side above the second liquid level.

[0114] For example, in some embodiments, by operating the second water pump, the second liquid level in the first filter box is lowered to or below the third opening of the first filter box. This means that most of the sides of the first filter box are above the second liquid level, allowing the water jet from the first nozzle to clean most of the sides of the first filter box. For instance, if the second water pump is off before adjusting the second liquid level, the controller turns it on when adjustment is needed. Alternatively, if the second water pump is running before adjusting the second liquid level, the controller increases its operating parameters when adjustment is required. Furthermore, the base station also includes a sensor to detect the second liquid level, allowing the controller to control the second water pump to start or adjust its operating parameters based on the sensor's detection signal.

[0115] Alternatively, in some embodiments, the operation of the second water pump adjusts the height of the second liquid level in the first filter box to a preset height; once the second liquid level reaches the preset height, it is kept at the preset height to facilitate the first nozzle spraying liquid to clean the side of the first filter box.

[0116] For example, a first filter screen is provided on the side of the first filter box to form a first filter surface. Debris easily adheres to the first filter screen, so when the first nozzle cleans the side of the first filter box, it primarily cleans the first filter screen. The second water pump adjusts the height of the second liquid level to ensure that the first filter screen is positioned above the second liquid level, i.e., in the air environment. Alternatively, in some embodiments, a first filter screen may or may not be provided at the bottom of the first filter box. If a first filter screen is provided at the bottom of the first filter box, the second water pump adjusts the second liquid level to ensure that the first filter screen at the bottom of the first filter box is also positioned above the second liquid level, facilitating the cleaning of debris adhering to the first filter screen when the first nozzle sprays liquid onto the bottom of the first filter box.

[0117] In other words, if most or all of the first filter screen is below the second liquid surface, the liquid in the first filter box needs to be sucked away by the operation of the second water pump, so that most of the first filter screen is above the second liquid surface, that is, the first filter screen is in the air environment, which makes it easier for the first nozzle to spray liquid onto the first filter screen to wash away the garbage attached to the first filter screen.

[0118] Furthermore, if the base station is placed in a pool or designated area, when the pool robot is stationary on the base station, if the first liquid level in the pool is higher than the first outlet, when the second water pump operates to adjust the height of the second liquid level, the liquid in the pool will flow back through the first outlet into the first filter box. This increases the amount of water entering the first filter box, requiring the water pump to operate at higher parameters to lower the second liquid level so that most of the first filter screen is above the second liquid level. Therefore, in actual use, it is best to keep the first liquid level below the first outlet; however, it can also be above the first outlet. Alternatively, if the base station is placed in a pool or designated area, the second liquid level in the first filter box can be adjusted without using the second water pump; the first nozzle can also spray water onto the sides and bottom of the first filter box to clean it, although the cleaning effect is relatively weaker, it can still clean most of the debris inside the first filter box.

[0119] In some embodiments, if the base station is placed inside a pool or in a designated area, the pool robot is charged wirelessly by the base station.

[0120] In some embodiments, if the base station is placed in a pool or within a designated area, the water source for cleaning the first filter box can be liquid from the pool. In this case, the base station also includes the aforementioned first water pump to pump the liquid from the pool to the first nozzle. Alternatively, the water source for cleaning the first filter box can be municipal water from the user's home, such as tap water. In this embodiment, the liquid filtered by the second filter box can be discharged back into the pool for reuse; alternatively, it can be pumped into the user's sewer or onto the user's outdoor lawn by the operation of the second water pump.

[0121] Furthermore, regardless of whether the base station is used on land or on the ground, or placed in a pool or designated area, the base station also includes a pressurization component to ensure that the water jet from the first nozzle is high-pressure. The pressurization component can be located in the waterway between the clean water source and the first nozzle. For example, the pressurization component includes, but is not limited to, a booster pump, a water hammer pump, a pressure tank, a mechanical pressurization device, an elevated water tank, etc., or the water pressure of the jet from the first nozzle can be increased by reducing the size of the nozzle on the first nozzle.
