[0006] This application relates to the field of pool cleaning equipment technology, and more specifically, to a cleaning system. Background Technology

[0007] With the improvement of people's living standards, swimming pools have become a common facility in many homes and public places. To maintain the cleanliness of swimming pools, pool robots, as an automated cleaning device, are widely used. During the use of pool robots, the filter box, as a key component for collecting impurities, is crucial, and its cleaning and maintenance directly affect the robot's working efficiency and lifespan.

[0008] Currently, pool robots on the market are usually equipped with a detachable first filter box for collecting trash in the pool. In order to facilitate the cleaning of trash in the first filter box of the pool robot, existing technology has a base station that transfers the trash in the first filter box into the inner cavity of the base station and then discharges the trash outside the base station. That is, the base station only acts as a transfer station or a transition channel to transfer the trash in the first filter box outside the base station. If the trash is discharged directly from the outside of the base station into the outdoors, sewers, or pools, it can easily cause secondary pollution. Summary of the Invention

[0009] This invention aims to solve the above-mentioned problems. This application discloses a cleaning system including a pool robot, a base station, and an unlocking mechanism, which is used to clean the first filter box of the pool robot and collect the garbage in the first filter box, avoiding the pollution and inefficiency caused by manual operation; at the same time, the unlocking mechanism enables the automatic opening of the first bottom cover without manual intervention.

[0010] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0011] This application provides a cleaning system, including a pool robot, a base station, and an unlocking mechanism;

[0012] The pool robot includes a first filter box, which is at least partially located inside the pool robot.

[0013] The first filter cartridge includes at least:

[0014] First framework;

[0015] The third opening is located, at least partially, at the bottom of the first frame;

[0016] The first bottom cover is movably mounted on the first frame and is used to open or close the third opening;

[0017] The locking mechanism has a locked state and an unlocked state; in the locked state, the locking mechanism is used to lock the first bottom cover onto the first frame, so that the first bottom cover remains closed to the third opening; in the unlocked state, the locking mechanism releases the lock on the first bottom cover, and the first bottom cover can move relative to the first frame to at least open the third opening.

[0018] Among them, base stations include at least:

[0019] The second filter box is used to receive at least the waste from the first filter box;

[0020] The unlocking mechanism is used to drive the locking mechanism to move, so that the locking mechanism switches from the locked state to the unlocked state.

[0021] This application sets up a second filter box to receive the waste in the first filter box, so as to automatically transfer the waste in the first filter box to the second filter box; in addition, the waste received by the second filter box is further filtered, and the filtered liquid is discharged from the base station in a timely manner, which can prevent the waste from smelling bad in the second filter box.

[0022] This application incorporates an unlocking mechanism to drive the locking mechanism on the first filter box, causing the locking mechanism to switch from a locked state to an unlocked state. When the locking mechanism is unlocked, the first bottom cover can be opened by driving force to disengage from the bottom of the first filter box, enabling automatic waste disposal. When the locking mechanism is locked, the reset first bottom cover can be locked to the bottom of the first filter box by the locking mechanism, thus resealing the bottom of the first filter box. Therefore, the unlocking mechanism enables waste to be poured out from the bottom of the first filter box, allowing the cleaning system to automatically complete the sludge discharge process.

The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality" means two or more, unless otherwise explicitly defined.

[0096] As shown in Figures 1 and 34, this application provides a cleaning system including a pool robot 1000 and a base station 2000. As shown in Figures 54 and 55, the base station is used at least to clean the first filter box 1051 of the pool robot, so that waste in the first filter box is transferred from the pool robot or temporarily stored in the base station. Further, as shown in Figure 37, in some embodiments, the base station includes at least a base station body and a second filter box 21102. At least a portion of the second filter box is located within the base station body, and the second filter box is used to receive waste from the first filter box and further filter it.

[0097] As shown in Figures 34, 36, 54, and 55, in some embodiments, the base station further includes a first nozzle 2173; wherein the first nozzle cleans the first filter box by spraying liquid onto it. When the pool robot stops on the base station body, it cleans the first filter box by spraying liquid through the first nozzle, and the debris in the first filter box falls into the second filter box, thereby transferring the debris from the first filter box to the second filter box.

[0098] The pool robot 1000 is used to perform tasks such as cleaning, disinfection, and rescue 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 pool bottom and pool walls.

[0099] In some embodiments, as shown in Figures 1 and 2, the pool robot includes a first body 1001, at least one liquid inlet, at least one first filter box 1051, at least one liquid outlet, and at least one suction assembly. The liquid inlet is used to allow liquid from the pool to enter the first body 1001 of the pool robot, enabling the pool robot to clean at least one of the following: pool bottom, pool walls, waterline, and water surface.

[0100] At least a portion of the first filter box is disposed within the first main body. The first filter box is used to filter the liquid entering it. The liquid outlet is used to discharge the liquid filtered by the first filter box out of the first main body. The suction assembly is used to generate suction force. Under the action of the suction assembly, the dust-laden water in the pool is drawn into the first filter box through the liquid inlet and filtered by the first filter box. The garbage carried in the liquid remains in the first filter box. After passing through the suction assembly, the filtered liquid is finally discharged out of the first main body through the liquid outlet.

[0101] In some embodiments, as shown in Figures 1, 2, and 4, the liquid inlet section includes at least a first water inlet 1031, the liquid outlet section includes at least a first water outlet 1041, and the suction assembly includes a main water pump 1061; the first water inlet 1031, the first filter box 1051, the main water pump 1061, and the first water outlet 1041 are sequentially fluidly connected to form a first water path, which is used to clean the bottom wall, side wall, or waterline of the pool.

[0102] In other embodiments, as shown in Figures 1, 2, and 3, the liquid inlet section includes at least a second water inlet 1032, the liquid outlet section includes at least a first water outlet 1041, and the suction assembly includes a main water pump 1061; the second water inlet 1032, the first filter box 1051, the main water pump 1061, and the first water outlet 1041 are sequentially connected to form a second water path for cleaning the water surface and water line.

[0103] In some embodiments, as shown in Figures 1 and 2, a second baffle 10511d is provided at the second water inlet. When the pool robot is cleaning the water surface, the second baffle is in the open state, allowing liquid to enter the first filter box through the second water inlet. In some embodiments, the second baffle is rotatably mounted on the first body to open and close the second water inlet. For example, the second baffle can be opened by rotating outward toward the first body; the second baffle can be closed by rotating from the outside of the first body toward the second water inlet.

[0104] Furthermore, the second baffle is rotatably disposed on the side of the first body. Furthermore, in some embodiments, after the second baffle opens the second water inlet, the first nozzle extends through the second water inlet into or out of the first filter box.

[0105] In some embodiments, as shown in FIG1, a fourth inlet 1016 is provided on the first body, which communicates with the first filter box, so that the first nozzle can extend into the first body or exit the pool robot through the fourth inlet. Since the first nozzle can extend into the first body to spray liquid onto the first filter box, the liquid sprayed by the first nozzle can be sprayed onto the first filter box, ensuring the cleaning effect of the first filter box.

[0106] In some embodiments, the fourth inlet may be the first water inlet or the second water inlet; when the first body is provided with a pick-and-place port, the fourth inlet may also be a pick-and-place port, which is used for the user to put the first filter box into the first body or to take the first filter box out of the first body. Alternatively, in other embodiments, the fourth inlet may be independent of the first water inlet and the second water inlet, and the pick-and-place port may be located on the first body.

[0107] In some embodiments, the first body is the outer shell of a pool robot, and the first body includes at least a bottom shell, an upper shell, and at least one side shell. For example, in a specific embodiment, as shown in Figures 4 and 5, the first body 1001 is composed of a front shell 1001c, a rear shell 1001d, an upper shell 1001e, a bottom shell 1001f, a first side shell 1001g, and a second side shell 1001h to form a closed outer shell structure. The front shell is connected to the front end or front part of the bottom shell, the first side shell, the second side shell, and the upper shell, and the rear shell is connected to the rear end or rear part of the bottom shell, the first side shell, the second side shell, and the upper shell to form the first outer shell.

[0108] In some embodiments, as shown in Figures 5 and 6, the first body further includes a first dust chamber 1052, which is disposed within the first body, and the inner cavity of the first dust chamber serves as a first receiving cavity. For example, the first dust chamber is fixed to the upper shell, or the first dust chamber is fixed to the bottom shell; or, the first dust chamber is integrally formed on the bottom shell or the upper shell. In some embodiments, the loading and unloading port is located on the top of the first dust chamber, and the first filter box is disposed within the first dust chamber.

[0109] For example, in some embodiments, the first dust chamber is fixed to the aforementioned bottom shell; or, the first dust chamber is fixed to the aforementioned upper shell. As an alternative embodiment of the first dust chamber, the first dust chamber can be replaced by a partition, which is arranged to form a first receiving cavity.

[0110] In some embodiments, all internal cavities within the first body other than the first receiving cavity can serve as second receiving cavities. For example, in some embodiments, a first dust bin is disposed within the first body, and the internal cavity of the first dust bin serves as the first receiving cavity; then, the cavity formed between the inner wall of the first body and the outer wall of the first dust bin serves as the second receiving cavity.

[0111] In some embodiments, to discharge waste from the first filter box, as shown in Figures 1 and 2, the first filter box includes at least one third opening 10531 and a first bottom cover 1054, which can open and close the third opening. At least a portion of the third opening is located on the bottom of the first filter box, as shown in Figures 54 and 55. When the pool robot stops on the base station body, after the first bottom cover opens the third opening, the third opening can communicate with the third inlet of the second filter box, allowing waste and liquid in the first filter box to be discharged from the third opening and fall into the second filter box through the third inlet.

[0112] In some embodiments, as shown in Figures 1, 2, and 58A to 58C, the first filter box 1051 includes a first frame 1053, the aforementioned first bottom cover 1054, and a first filter screen 1055; at least a portion of the third opening is disposed on the bottom of the first frame. Alternatively, the bottom opening of the first frame serves as the third opening; the first filter screen is disposed on at least one side wall of the first frame to form a filter surface for filtering liquid entering the first filter box; the first bottom cover is movably disposed on the first frame to open and close the third opening. In some embodiments, the material of the first filter screen may be non-woven fabric, nylon, filter cotton, or other materials with filter pores.

[0113] In some embodiments, as shown in FIG4, a seventh opening 1033 is provided at the bottom of the first body. In some embodiments, as shown in FIGS. 54 and 55, at least a portion of the third opening is located above at least a portion of the seventh opening in the height direction of the pool robot. When the first base opens the third opening, the waste in the first filter box is discharged out of the pool robot sequentially through the third opening and the seventh opening. In this embodiment, the seventh opening not only allows the waste to be discharged out of the pool robot, but also needs to avoid the movement of the first bottom cover. That is, the seventh opening serves as the first drain outlet for the waste in the first filter box to be discharged out of the pool robot. For example, the first base is rotatably disposed at the third opening, and the seventh opening needs to avoid the rotation of the first base.

[0114] In other embodiments, the seventh opening is located above the third opening, or flush with the third opening. When the first base opens the third opening, the waste in the first filter box is directly discharged from the pool robot through the third opening. In this case, the seventh opening mainly serves to allow the first bottom cover to rotate and expose the first base to the external environment when the first bottom cover closes the third opening; or exposes the third opening to the external environment when the first bottom cover opens the third opening. For example, the first base rotates below the seventh opening to open or close the third opening.

[0115] In some embodiments, as shown in FIG5, the pool robot further includes a loading / unloading port 1017, which communicates with the first main body and is used for a user to place the first filter box into the first main body or remove the first filter box from the first main body. This loading / unloading port can be located on the top, side wall, or bottom of the pool robot.

[0116] In some embodiments, the first inlet 1031 is located at the bottom of the first main body 1001. Correspondingly, the first filter box is provided with a first inlet 10511a, which communicates with the first inlet 1031, so that the liquid in the pool enters the first filter box 1051 for filtration through the first inlet 1031. In other embodiments, the first filter box is provided with a second inlet 10511b, which communicates with the second inlet 1032, so that the liquid on the surface of the pool enters the first filter box 1051 for filtration through the second inlet 1032.

[0117] For example, the first inlet is located at the bottom of the first filter box, and the first inlet is connected to the first water inlet. In other embodiments, when the second water inlet is located on the front side wall of the first main body, correspondingly, the second inlet is located on the front side wall of the first filter box, and the second water inlet is located in front of and connected to the second inlet; or, when the second water inlet is located on the rear side wall of the first main body, correspondingly, the second inlet is located on the rear side wall of the first filter box, and the second water inlet is located behind and connected to the second inlet, so that the pool liquid can directly enter the first filter box from the second water inlet and the second water inlet. That is, the second water inlet is located outside the second inlet.

[0118] In other embodiments, as shown in Figures 4, 58A, 58B, and 58C, the first inlet is located on the bottom of the first filter box. For example, the first inlet is located on the first bottom cover, and the bottom of the first filter box is exposed above the first main body or connected to the outside. Liquid in the pool enters the first filter box through the first inlet. That is, the first inlet and the first entrance are a single opening. For example, as shown in Figure 4, a seventh opening is provided on the bottom of the first main body, exposing the first bottom cover to the outside.

[0119] Alternatively, a first protrusion may be provided on the bottom of the first filter box, extending into the first filter box. The first protrusion is hollow to form a liquid inlet channel. The outer end of the liquid inlet channel serves as the first water inlet, and the inner end of the liquid inlet channel serves as the first inlet, so that liquid in the pool enters the first filter box through the first water inlet and the first inlet. The first protrusion moves synchronously with the first bottom cover to open or close the third opening. Alternatively, the entire liquid inlet channel may serve as the first water inlet or the first inlet.

[0120] In some embodiments, as shown in Figures 58B and 58C, a first baffle 10511c is provided on the first inlet / first water inlet, which is used to open and close the first inlet / first water inlet. In other embodiments, a second baffle 10511d is provided on the second inlet / second water inlet, which is used to open and close the second inlet / second water inlet. When the pool robot is cleaning the water surface, the second baffle opens the second inlet / second water inlet to allow liquid to enter the first filter box from the second water inlet / second water inlet. When the pool robot is cleaning the bottom of the pool, the first baffle opens the first inlet / first water inlet to allow liquid to enter the first filter box from the first water inlet / first water inlet.

[0121] In some embodiments, the first bottom cover is rotatably disposed on the first frame. Alternatively, in other embodiments, the first bottom cover 1054 is slidably disposed on the first frame 1053.

[0122] In some embodiments, the aforementioned first filter box has a first state and a second state. In the first state, the first filter box is installed inside the first body. In this first state, the pool robot is in the pool, and the first bottom cover closes the third opening. Alternatively, in this first state, the pool robot is stationary on the base station, and the first bottom cover at least opens the third opening to allow waste in the first filter box to be discharged from the first body through the third opening. In the second state, the first filter box is located outside the first body. In this second state, the first bottom cover is movable between opening and closing the third opening. Furthermore, during the transition from the first state to the second state, the first bottom cover remains closed with the third opening closed.

[0123] In this embodiment, in the first state, the pool robot is in the pool, and the first bottom cover closes the third opening to prevent trash in the first filter box from falling into the pool. In the second state, the pool robot is stationary on the base station, and the first bottom cover opens the third opening to facilitate the discharge of trash from the first filter box. In the third state, the first filter box is separated from the first main body, and the first bottom cover can switch between opening and closing the third opening, allowing users to choose to open or close the third opening according to their needs. During the transition from the first state to the second state, the first bottom cover remains closed with the third opening closed to ensure that trash in the first filter box does not fall out of the third opening when the user removes the first filter box from the first main body.

[0124] In some embodiments, as shown in Figures 34, 37, and 53, the base station body includes a third receiving cavity 2054, and at least one fourth opening 2055 is disposed on the base station body and communicates with the third receiving cavity; at least a portion of the second filter box is disposed in the third receiving cavity; the fourth opening and the third inlet are communicated; as shown in Figure 55, when the pool robot stops on the base station body and the first bottom cover rotates outward toward the pool robot to open the third opening, at least a portion of the first bottom cover engages with the fourth opening, so that the waste in the first filter box falls sequentially from the third opening, the fourth opening, and the third inlet into the second filter box.

[0125] In some embodiments, the second filter box has at least one filter surface for filtering liquids and waste entering therein, and retaining the waste inside the second filter box. The second filter box is provided with at least one third inlet, which serves as the entry point for waste into the second filter box. When the pool robot stops on the base station body, the third inlet can communicate with the third opening of the first filter box, allowing waste in the first filter box to enter the second filter box through the third opening and the third inlet.

[0126] The swimming pool robot rests on the base station body. The first nozzle sprays liquid into the first filter box. After the first bottom cover of the first filter box opens to the third opening, the debris inside the first filter box and the liquid sprayed from the first nozzle enter the second filter box through the third opening and third inlet. The debris remains in the second filter box, while the liquid is filtered and discharged from the base station body. This process collects or temporarily stores the debris from the first filter box into the second filter box, completing the cleaning of the first filter box. No user intervention is required during the cleaning process of the first filter box, achieving automatic cleaning.

[0127] In some embodiments, the second filter box includes a second frame and a second filter screen. The second filter screen is disposed on the second frame to form a filter surface. Alternatively, in other embodiments, the second filter box is a first filter bag, which can be a disposable filter bag or a reusable filter bag. If the second filter box is a disposable filter bag, when the first filter bag is full of garbage, the first filter bag can be directly discarded to replace it with a new one, without the need to clean the first filter bag. Alternatively, the second filter screen can be replaced with filter cotton, which can be disposed outside or inside the second frame. For example, the filter cotton is made of polyester fiber. For example, the filter cotton can be detachably disposed on the second frame.

[0128] In some embodiments, the first bottom cover only needs to open the third opening when the waste in the first filter box needs to be discharged from the third opening. For example, when the pool robot is parked on the base station, and the first nozzle is cleaning the first filter box, it needs to discharge the waste in the first filter box into the second filter box of the base station, which requires the first bottom cover to open the third opening; or, for example, when the user removes the first filter box from the pool robot, the user manually operates the first bottom cover to open the third opening.

[0129] When the pool robot is in the pool, or on the shore and does not need to discharge waste from the first filter box through the third opening, the first bottom cover is in the closed third opening state (as shown in Figure 2). For example, when the pool robot is performing cleaning in the pool, the first filter box is in the first receiving cavity, and the first bottom cover always keeps the third opening closed so that the waste in the first filter box 1051 will not be discharged from the third opening, thus not affecting the pool robot's cleaning of the pool bottom, pool walls, waterline, or water surface. Alternatively, when the pool robot is on the shore, it may or may not be on the base station, but it is not in the process of the first nozzle cleaning the first filter box. If the user wants to remove the first filter box 1051 from the first body 1001, to ensure that the user removes the first filter box during or after removal, and before the user manually opens the first bottom cover, the first bottom cover remains closed with the third opening closed to prevent waste in the first filter box 1051 from falling out through the third opening.

[0130] Therefore, in some embodiments, the first bottom cover 1054 has a locked state and an unlocked state, wherein when the first bottom cover is in the locked state, the first bottom cover is locked on the first frame and keeps the third opening closed; when the first bottom cover is in the unlocked state, the first bottom cover can move relative to the first frame to switch between opening and closing the third opening.

[0131] In some embodiments, as shown in Figures 1 and 14, a third opening 10531 is disposed on the bottom of the first filter box. The first bottom cover 1054 includes a first base, which is used to open and close the third opening. When the first base opens the third opening, the waste in the first filter box is discharged from the first filter box through the third opening. The first bottom cover also includes a first protrusion (or described as a dust box liquid inlet), which is disposed on the first base and extends into the interior of the first filter box. The first protrusion is hollow to form a liquid inlet channel. The outer end of the first protrusion serves as a first water inlet, and the inner end serves as a first inlet, so that liquid in the pool enters the first filter box through the first water inlet and the first inlet. The first protrusion moves synchronously with the first base to open or close the third opening. Alternatively, the entire liquid inlet channel can be used as the first water inlet or the first inlet. Alternatively, in some other embodiments, the first bottom cover also includes a second base, which is disposed on the first base. At least a portion of the second base is disposed around the outer periphery of at least a portion of the first protrusion, and the first base, the first protrusion, and the second base form a first mounting cavity.

[0132] In some embodiments, as shown in Figures 6, 7, and 8, the pool robot further includes a locking mechanism 1080, which has a locked state and an unlocked state. In the locked state, the locking mechanism is used to lock the first bottom cover to the side wall of the first frame or the first filter box, so that the first bottom cover remains closed at the third opening. In the unlocked state, the locking mechanism releases the lock on the first bottom cover, and the first bottom cover can move relative to the side wall of the first frame or the first filter box to at least open the third opening. Correspondingly, the pool robot or the base station body is provided with an unlocking mechanism, which is used to drive the locking mechanism to move, so that the locking mechanism switches from the locked state to the unlocked state.

[0133] There are various implementations for the locking mechanism. For example, in some embodiments, the locking mechanism locks the first bottom cover to the first frame using magnetic attraction. For instance, the locking mechanism 1080 includes a first magnet and a first iron block, wherein one of the first magnet and the first iron block is disposed on the first bottom cover, and the other is disposed on the first frame. The first magnetic attraction force generated by the magnet and the iron block locks the first bottom cover to the first frame. In this embodiment, the unlocking mechanism includes a first motor and a second unlocking member, wherein the second unlocking member can be a second magnet or a second iron block. The first motor drives the second unlocking member to move, so that the second unlocking member approaches or contacts the first magnet or the first iron block, and the second iron block generates a third magnetic attraction force with the first magnet; or, the second magnet and the first iron block generate a third magnetic attraction force, which is greater than the first magnetic attraction force, driving the first bottom cover to rotate, so that the first magnet and the first iron block move away, thereby releasing the locking mechanism from locking the first bottom cover.

[0134] Alternatively, the locking mechanism 1080 includes a first magnet and a second magnet, one of which is disposed on the first bottom cover and the other on the first frame. One end of the first magnet and one end of the second magnet have opposite polarities to generate a second magnetic attraction force, magnetically attracting the first bottom cover to the first frame. In this embodiment, the unlocking mechanism includes a first motor and a second unlocking member. The second unlocking member can be iron or a third magnet. The first motor drives the second unlocking member to move, causing it to approach or contact the first or second magnet. A fourth magnetic attraction force is generated between the second unlocking member and the first or second magnet. This fourth magnetic attraction force is greater than the second magnetic attraction force, driving the first bottom cover to rotate, causing the first magnet to move away from the second magnet, thereby releasing the locking mechanism from locking the first bottom cover.

[0135] Alternatively, the locking mechanism 1080 includes a first coil and a second coil, one of which is disposed on the first frame and the other on the first bottom cover. By energizing the first coil and the second coil, an electromagnetic field is generated to form a fifth magnetic attraction force, which magnetically attracts the first bottom cover to the first frame. Conversely, by de-energizing at least one of the first coil and the second coil, the fifth magnetic attraction force is removed, thereby releasing the lock on the first bottom cover.

[0136] In other embodiments, the locking mechanism locks the first bottom cover onto the first frame via a latch. For example, the locking mechanism includes a hook and a first mating member, wherein the first mating member can be one of a slot, a hole, a seat (or a boss); one of the hook and the first mating member is located on the first bottom cover, and the other is located on the first frame. The hook engages with the slot or hole, or with the seat, to lock the first bottom cover onto the first frame. In this embodiment, the unlocking mechanism includes a motor and a second unlocking member. The motor drives the second unlocking member to rotate, forcing the first bottom cover to rotate, causing the hook to disengage from the first mating member, thereby releasing the locking mechanism from locking the first bottom cover. In some embodiments, the motor is located on the first bottom cover; in another embodiment, the first motor is located within the first frame or the first body. When the first bottom cover closes the third opening, the motor is driven to connect with the second unlocking member; when the motor drives the second unlocking member to rotate the first bottom cover, the motor disengages from the second unlocking member. For example, the second unlocking component includes a first gear, and a second gear is provided on the first bottom cover. When the first bottom cover closes the third opening, the first gear and the second gear mesh; when the first bottom cover opens the third opening, the first gear and the second gear disengage.

[0137] In other embodiments, as shown in Figures 8 and 25, the locking mechanism locks the first bottom cover onto the first frame by extending; correspondingly, the unlocking mechanism drives the locking mechanism to retract to release the locking mechanism from locking the first bottom cover, so that the first bottom cover can move relative to the first frame to open or close the third opening.

[0138] In some embodiments, as shown in Figures 8, 9, 15, and 16, the locking mechanism includes a first limiting portion and a first locking member 10802. The first locking member is slidably disposed relative to the first limiting portion, and one of the first locking member and the first limiting portion is disposed on the first bottom cover, while the other is disposed on the first frame. In the locked state, the locking portion of the first locking member extends into the first limiting portion; in the unlocked state, the locking portion of the first locking member retracts from the first limiting portion and separates from it.

[0139] Furthermore, as shown in Figures 12, 13, and 15, the locking mechanism further includes at least one fourth elastic element 10803. The fourth elastic element is connected to the first locking element, and the fourth elastic element applies a first biasing force, a first preload, or a first elastic force to the first locking element, forcing the locking portion of the first locking element to tend to remain within the first limiting portion.

[0140] For example, as shown in Figures 9, 10, and 16, the first limiting part includes at least a first limiting hole 10801, one of the first locking member and the first limiting hole is provided on the first frame, and the other is provided on the first bottom cover; the fourth elastic member applies its elastic force to the first locking member, forcing the first locking member to tend to extend, so as to remain in the first limiting hole and lock the first bottom cover on the first frame; correspondingly, the unlocking mechanism is used to drive the first locking member to retract and move to exit the first limiting hole.

[0141] For example, as shown in Figures 9, 10, 15 and 16, 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 locking part 108021 and a first mounting end 108022; the fourth elastic member is a compression spring, one end of which is provided on the first mounting end of the first locking member, and the other end is provided on the first bottom cover; the compression spring applies a first elastic force to the first locking member in the direction of the first limiting hole, causing the locking part 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 with the third opening closed.

[0142] In some embodiments, as shown in Figures 8 and 9, one of the first bottom cover and the first frame has an inwardly recessed first mounting cavity 1054d, and the other has a first limiting portion 10532, with the first limiting portion located outside the first mounting cavity; a first locking member is slidably disposed in the first mounting cavity; a fourth elastic member is disposed in the first mounting cavity and connected to the first locking member, and under the action of a first pre-tightening force, at least a portion of the locking portion is located outside the first mounting cavity.

[0143] For example, as shown in Figures 8, 9, and 11, a first mounting cavity is provided on a first bottom cover, and a first extension 10532 is provided on a first frame. The first extension is located outside the first mounting cavity, and a first limiting part is provided on the first extension. Specifically, the first mounting end of the first locking member is located inside the first bottom cover, and the locking part can extend out of the first bottom cover and into the first extension, for example, into the first limiting hole. The first bottom cover includes a first mounting cavity, the first mounting end of the first locking member is located inside the first mounting cavity, and a fourth elastic member is located inside the first mounting cavity.

[0144] In some embodiments, as shown in Figures 8 and 9, the first mounting cavity includes at least a guide channel extending along the sliding direction of the first locking member, and at least a portion of the first locking member is slidably disposed within the guide channel. Further, as shown in Figures 8 and 16, the first mounting cavity also includes a first sliding hole located at one end of the guide channel and communicating with it; at least a portion of the first locking member is slidably disposed within the guide channel and at least a portion is slidably disposed within the first sliding hole. Specifically, the first bottom cover has a first sliding hole 10804, and the guide channel communicates with the first sliding hole 10804. The locking portion of the first locking member passes through the first sliding hole and is located outside the first bottom cover; or, the first mounting end of the first locking member is located within the first mounting cavity, and the locking portion of the first locking member is located outside the first bottom cover. For example, in a specific embodiment, the first mounting cavity is formed by the aforementioned first base, second base, and first protrusion. A first extension portion is protruding from one side of the first frame, and a first limiting hole 10801 is formed on the first extension portion and aligned with the first sliding hole 10804.

[0145] In another embodiment, the first mounting cavity can be located on the first frame, and the first bottom cover has a first extension located outside the first mounting cavity; a first limiting part is located on the first extension. The above functions can be achieved in the same way.

[0146] In some embodiments, as shown in Figures 15 and 19, a first inclined surface 108026 is provided at the end of the first locking member that is away from the fourth elastic member. When the first bottom cover, along with the locking mechanism, flips up and returns to its original position, before entering the first limiting hole, the first inclined surface 108026 first contacts the outer wall of the first limiting hole. The outer wall of the first limiting hole presses against the first inclined surface, causing the first locking member to retract, and then flips up to smoothly enter the first limiting hole for limiting.

[0147] As shown in Figures 17 and 19, since the first mounting end slides within the first sliding hole, small debris such as sand can easily cause jamming if it enters the hole. Therefore, the first mounting end is provided with at least one first protrusion 10823 at circumferential intervals, and the first protrusion 10823 is slidably connected to the inner wall of the first sliding hole. For example, if the first mounting end is provided with multiple first protrusions 10823 at circumferential intervals, if sand is present, it will be pushed into the gaps between the multiple first protrusions during the movement of the first mounting end, thus avoiding jamming when the first mounting end slides within the first sliding hole.

[0148] In some embodiments, as shown in Figures 8, 9, and 13, one end of the fourth elastic member 10803 abuts against the first sliding hole, and the other end of the fourth elastic member is sleeved on the outside of the first mounting end. In this embodiment, the first protrusion abuts against one end of the fourth elastic member to limit its movement.

[0149] In some other embodiments, as shown in Figures 10 and 12, a first opening 108025 is provided on one side of the first mounting end 108022, and a fourth elastic member 10803 is placed inside the first opening, that is, one end of the fourth elastic member 10803 abuts against the first sliding hole, and the other end of the fourth elastic member is embedded in the first opening. The fourth elastic member is limited by the first opening, thereby facilitating the installation of the fourth elastic member.

[0150] In some embodiments, as shown in Figures 16, 17, 18, and 19, a second protrusion 108024 is provided on the first mounting end, and a limiting groove 10543 is provided on the first bottom cover. The second protrusion is movably embedded in the limiting groove to achieve matching and limiting. The movement of the first locking member is achieved by the second protrusion moving in the limiting groove.

[0151] In other embodiments, as shown in Figures 19, 20, and 21, a limiting protrusion 10544 is provided at the opening end of the limiting groove 10543, dividing the limiting groove into a first inner groove 10545 and a second opening 10546. The first inner groove is located on the side of the limiting protrusion away from the first limiting hole, and the second opening is located on the side of the limiting protrusion, making the width of the second opening smaller than the width of the limiting groove. The second opening is connected to the first inner groove, so that when the first locking member is installed, the second protrusion is inserted into the limiting groove from the second opening and then rotates upward into the first inner groove (for axial limiting). At this time, the elastic force of the fourth elastic member cannot eject the first locking member, thus making assembly more convenient. As shown in Figures 13 and 14, a blocking member 10547 is provided on the first bottom cover. The blocking member 10547 can abut against one side of the limiting protrusion, thereby blocking the second opening and preventing the second protrusion from moving out from the bottom of the first inner groove, thus realizing the function of longitudinal blocking and limiting.

[0152] In some embodiments, the limiting groove can be provided on the second base, and the blocking member 10547 can be provided on the first base 10541. During the assembly process, the first base 10541 is assembled onto the second base 10542. At this time, the blocking member 10547 extends into the limiting groove to block the second protrusion.

[0153] Furthermore, in some embodiments, since the fourth elastic member applies a first preload force toward the outside of the first bottom cover to the first locking member, in order to prevent the first locking member from sliding outward from the first bottom cover and detaching from the first bottom cover, as shown in FIG16, the locking mechanism further includes a first limiting component. The first limiting component is disposed on the first bottom cover and is used to block the first locking member on the first bottom cover. For example, in some embodiments, the first limiting component includes a second sliding hole 10805 and a first limiting member 10806, wherein the first limiting member is fixedly or detachably connected to the first locking member, the second sliding hole is disposed on the first bottom cover, and the second sliding hole and the first sliding hole are staggered in the horizontal or vertical direction. The first limiting member moves synchronously with the first locking member and slides in the second sliding hole, thereby limiting the first locking member on the first bottom cover.

[0154] In other embodiments, after the first filter cartridge is removed from the pool robot, the user can press the first limiting member 10806 to drive the first locking member to retract, thereby manually releasing the first locking member from locking the first bottom cover. This allows the first bottom cover to move, opening the third opening, or the user can manually close the first bottom cover to the third opening. As shown in Figures 17 and 18, a button 10807 is further provided on one end of the first limiting member, allowing the user to unlock the first bottom cover by pressing the button. Alternatively, in other embodiments, the user can also directly press the first locking member to retract, manually releasing the first locking member from locking the first bottom cover. In this embodiment, the locking mechanism may or may not include the first limiting component.

[0155] As shown in Figures 17 and 18, for example, a button 10807 is provided on the end of the first limiting member that protrudes outside the first bottom cover. When the first filter box is removed, the user can directly press the button, causing the first limiting member to retract into the first bottom cover, and similarly disengaging the first locking member from the first limiting hole, thereby unlocking the first bottom cover and completing the manual cleaning of the first filter box. When the first filter box is inside the main body of the pool robot, the first locking member can be extended or retracted directly or indirectly through the unlocking mechanism to achieve unlocking.

[0156] In some embodiments, as shown in FIG18, the first sliding hole 10804 and the second sliding hole 10805 can be combined into one large hole, that is, the first sliding hole and the second sliding hole can be the same hole.

[0157] In some embodiments, the unlocking mechanism drives the first locking member to retract, thereby disengaging it from the first limiting hole. For example, the unlocking mechanism includes a cylinder that drives the first locking member to retract, causing the first locking member to disengage from the first limiting hole. Alternatively, in other embodiments, as shown in Figures 8 and 34-38, the unlocking mechanism includes at least one driving component and at least one unlocking component. The driving component includes at least a first motor 70035 that drives the unlocking component to extend, thereby pushing the first locking member to retract, thus disengaging the first locking member from the first limiting hole. Alternatively, in other embodiments, the first motor drives the first locking member to rotate, thereby disengaging it from the first limiting hole.

[0158] For example, in some embodiments, as shown in FIG8 or FIG24, the unlocking assembly includes at least a second unlocking member 70033, and a first motor is used to drive the second unlocking member to move, so that at least a portion of the second unlocking member extends into the first limiting portion, thereby pushing the locking portion out of the first limiting portion. For example, in one embodiment, as shown in FIG7, FIG8, and FIG9, the second unlocking member is slidably disposed on the first body, for example, the second unlocking member is slidably disposed on the first body in a generally horizontal direction, and the first motor is used to drive the second unlocking member to extend; or, in another embodiment, as shown in FIG24 and FIG25, the second unlocking member is rotatably disposed on the first body, and the first motor is used to drive the second unlocking member to rotate.

[0159] Furthermore, in a specific embodiment, as shown in Figures 13 and 25, the second unlocking member has a first force-receiving part 700606 and a first pushing part 700603; the first motor drives the first force-receiving part, causing the first pushing part to push the first locking member to slide.

[0160] In some embodiments, the first motor is disposed on the first body; or, in other embodiments, as shown in FIG36, the unlocking mechanism further includes at least one first unlocking member 70031 disposed on the base station body; the first motor is disposed on the base station, and the first motor drives the first unlocking member to move, so that the first unlocking member drives the second unlocking member to move, thereby causing at least a portion of the second unlocking member to extend into the first limiting portion. Further, the first unlocking member drives the first force-receiving portion of the second unlocking member, and the first pushing portion of the second unlocking member pushes the first locking member to slide. For example, the first motor is at least used to drive the first unlocking member to move upward in a generally vertical direction to drive the second unlocking member to move; or, the first motor is at least used to drive the first unlocking member to slide left and right in a generally horizontal direction to drive the second unlocking member to move; or, the first motor is at least used to drive the first unlocking member to move in other directions to drive the second unlocking member to move; or, in another embodiment, the first motor is at least used to drive the first unlocking member to rotate to drive the second unlocking member to move.

[0161] In some embodiments, as shown in Figures 8 and 9, the unlocking assembly further includes at least one fifth elastic member 70034. The fifth elastic member is connected to the second unlocking member and applies a second biasing force, a second preload, or a second elastic force to the second unlocking member, forcing the second unlocking member to remain outside the first limiting portion.

[0162] In some specific embodiments, as shown in Figures 8, 9, 11, and 12, the second unlocking member further includes a second telescopic member. A first force-receiving part 700606 and a first pushing part 700603 are disposed on the second telescopic member. A fifth elastic member applies its elastic force to the second telescopic member, forcing it to tend to stay away from the first limiting hole. A first motor drives the second telescopic member to extend into the first limiting hole, thereby pushing the first locking member to move and causing it to exit the first limiting hole. For example, the fifth elastic member is a compression spring, with one end connected to the second telescopic member and the other end disposed on the first main body, the first receiving cavity, or the first dust chamber. The second telescopic member is subjected to a second biasing force, a second pre-tightening force, or a second elastic force from the fifth elastic member and is located outside the first limiting hole. When the first motor removes its driving force on the second telescopic member, the second telescopic member returns to its original position outside the first limiting hole under the elastic action of the fifth elastic member. In some embodiments, the second telescopic member is arranged approximately horizontally.

[0163] In some embodiments, as shown in Figures 7-14, the second unlocking member 70033 further includes a second mating member 70032. The first motor drives the second mating member to move upward, so that the second mating member pushes the second telescopic member towards the first locking member, thereby pushing the first locking member out of the first limiting hole. For example, the second mating member includes a second pushing part 700605 and a second force receiving part 700604. The first unlocking member drives the second force receiving part of the second mating member to drive the second unlocking member to slide. Further, the second pushing part of the second mating member and the first force receiving part of the second unlocking member abut against each other through an inclined surface. Due to the effect of the inclined surface, when the second mating member moves upward, it can push the second telescopic member to move in the horizontal direction, thereby pushing the first locking member to retract. In some embodiments, the second mating member is arranged substantially vertically, that is, the second mating member is arranged on the first body in a substantially vertically movable manner.

[0164] For example, in one specific embodiment, at least a portion of the second mating member is disposed within the first main body, as shown in Figures 3 and 23. The first main body is provided with a third clearance opening 1001j, so that the bottom of the second mating member is connected to the outside, i.e., the second mating member is exposed. A first motor drives a first unlocking member to move upward. The first unlocking member pushes the second mating member upward through the third clearance opening 1001j, thereby driving the second telescopic member to move into the first limiting hole, and then pushing the first locking member to retract. The first locking member exits the first limiting hole, realizing the unlocking function of the first bottom cover. For example, in some embodiments, the initial position of the second mating member can be that the bottom of the second mating member is located within the third clearance opening; the first unlocking member pushes the second mating member upward by extending into the third clearance opening. Alternatively, in other embodiments, the initial position of the second mating member can be that the bottom of the second mating member is located within the first main body; the first unlocking member extends into the first main body through the third clearance opening to push the second mating member upward. Alternatively, in other embodiments, the initial position of the second mating member can be that the bottom of the second mating member extends beyond the bottom of the first main body; the first unlocking member drives the second mating member to move upward outside the first main body. When the first motor removes its force on the second mating member, the second mating member moves downward under its own weight, resetting to its initial position; simultaneously, under the action of the fifth elastic member, the second telescopic member moves to exit the first limiting hole, and the second telescopic member resets to its initial state: the second telescopic member and the second mating member are in a state of renewed contact through the aforementioned inclined surface.

[0165] Furthermore, as shown in Figures 3, 12, 22, and 23, the second force-bearing part of the second mating member is located in the third clearance opening 1001j. The second pushing part 700605 cooperates with the first force-bearing part of the second unlocking member. The first unlocking member extends into the third clearance opening and drives the second force-bearing part of the second mating member, so that the second pushing part of the second mating member contacts the first force-bearing part of the second unlocking member to drive the second unlocking member to slide. The first pushing part of the second unlocking member cooperates with the locking part of the first locking member to push the first locking member and unlock it.

[0166] In some embodiments, as shown in Figures 9 and 22, to achieve stable horizontal movement of the second telescopic member, a first housing 70050 is sleeved outside the second telescopic member and the fifth elastic member. The first housing is fixed to the first body and can be used to protect and (horizontally) limit the movement of the second telescopic member and the fifth elastic member. For example, the first housing is sleeved outside at least a portion of the second telescopic member and at least a portion of the fifth elastic member. The second telescopic member slides inside the first housing and extends to engage with the first locking member. The second telescopic member moves linearly guided by the first housing. In one embodiment, the first housing is fixed to the first dust chamber, for example, the first housing is fixed to the inner or outer side of the first dust chamber.

[0167] In some embodiments, as shown in Figures 9 and 22, in order to achieve stable vertical movement of the second mating member, a second housing 70051 is provided over the second mating member. The second housing is fixed to the first body and serves to protect and (vertically) limit the movement of the second mating member. For example, the second housing is fitted over at least a portion of the second mating member, and the second mating member slides within the second housing and extends to engage with the second telescopic member. The second mating member moves linearly guided by the second housing.

[0168] In some embodiments, as shown in FIG23, the second mating member is provided with at least one third limiting part 700321, such that the bottom surface of the second mating member does not protrude from the bottom surface of the first body and / or the second housing. That is, when the second mating member communicates with the outside through the third clearance opening 1001j, the bottom surface of the second mating member is not lower than the bottom surface of the first body and / or the second housing. For example, the bottom surface of the second mating member is approximately flush with the bottom surface of the first body and / or the second housing. Further, the first body and / or the second housing is provided with at least one limiting groove 700322; for example, the second mating member includes a mating column and a mating base. The mating column is fixed on the mating base, and the surface area of ​​the mating base is larger than the cross-sectional area of ​​the mating column, thereby forming an inverted T structure. A third limiting part is provided on one side of the mating base. Correspondingly, a retaining edge is provided around the edge of the third clearance opening 1001j in the first body. A limiting groove is opened on the retaining edge, and the limiting part slides in the limiting groove to realize the mating installation of the second mating member and the first body.

[0169] Alternatively, the first main body and / or the second housing may be provided with at least one limiting part, and the second mating part may be provided with at least one limiting groove. When the second telescopic member returns to its initial position under its own gravity, the limiting part is engaged in the limiting groove to limit the second telescopic member, keeping it in its initial position and preventing it from falling off the first main body.

[0170] In some embodiments, as shown in Figures 22 and 23, a groove 700511 is provided inside the second housing, and a protrusion 700512 is provided on the second mating member. The guide and limit of the second telescopic member are realized through the cooperation of the protrusion and the groove. Alternatively, the function can also be achieved by providing a protrusion inside the second housing and a groove on the second mating member.

[0171] In other embodiments, as shown in Figures 24-30 and 56, the aforementioned second unlocking member is rotatably disposed within the first main body; without the aforementioned second mating member, the first unlocking member drives the first force-receiving part 700606, and the first pushing part 700603 pushes the first locking member to slide. Specifically, the first motor drives the first unlocking member to move upward, and the first unlocking member drives the second unlocking member to rotate forward by pushing the first force-receiving part of the second unlocking member, causing the first pushing part of the second unlocking member to rotate into the first limiting hole, thereby pushing the first locking member to retract, and then the first locking member to exit the first limiting hole. The second pre-tightening force generated by the fifth elastic member tends to keep the first pushing part 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 on the first force-receiving part 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 first pushing part of the second unlocking member returns to the outside of the first limiting hole. In this embodiment, the fifth elastic element can be a torsion spring or a compression spring; alternatively, it can also be a tension spring. Alternatively, in another embodiment, the aforementioned second unlocking element is rotatably disposed within the first body; and the aforementioned second mating element is provided.

[0172] When the second unlocking member is rotatably mounted on the first body, as shown in Figures 24-30, the fifth elastic member is connected to the second unlocking member and generates a second biasing force, a second pre-tightening force, or a second elastic force on the second unlocking member. Under the second biasing force, the second pre-tightening force, or the second elastic force, the second unlocking member rotates in the first direction.

[0173] In the above embodiments, the first force-bearing part of the second unlocking member can be connected to the outside through the third clearance opening on the first body, and at least a part of the first unlocking member can be inserted into the third clearance opening to push the second unlocking member to move.

[0174] Furthermore, in some embodiments, as shown in Figures 26, 29, 31, and 32, the unlocking assembly further includes at least one second limiting part 700521. The first motor drives the second unlocking member to rotate in a second direction so that the first pushing part extends into the first limiting part. In the locked state, the second limiting part restricts the second unlocking member from rotating in a first direction so that the fifth elastic member generates a second pre-tightening force. That is, the setting of the second limiting part prevents the second unlocking member from rotating outward or in a direction away from the locking structure or the connecting hole.

[0175] As shown in Figures 26, 29, 31, and 32, for example, the second limiting part includes at least a communicating hole 10521; and / or, the second limiting part includes at least a third housing 70052, the third housing is disposed outside the first receiving cavity, and the cavity of the third housing communicates with the communicating hole.

[0176] In one embodiment, as shown in Figures 31 and 32, the third housing is fixed to the first body. Specifically, the third housing is fixed to the outside of the first dust chamber (e.g., inside the second receiving cavity 10522). At least a portion of the third housing is located above the first pushing part, used to limit the second unlocking member. In the unlocked state, the second unlocking member is in the initial position. At this time, at least a portion of the first pushing part of the second unlocking member abuts against the third housing. The third housing restricts the second unlocking member from rotating in the first direction, keeping the second unlocking member in the initial position, i.e., preventing the second unlocking member from rotating outward and moving away from the connecting hole. At this time, the fifth elastic member generates a second pre-tightening force. In this embodiment, when the second unlocking member is in the initial position, at least a portion of the first pushing part of the second unlocking member is located inside the connecting hole. In this embodiment, the third housing can form an annular cavity; or, the third housing can be an open cavity.

[0177] In other embodiments, the connecting hole is used to limit the rotation of the second unlocking member. In this case, a third housing may be provided, which only protects the second unlocking member from damage; or, the third housing and the connecting hole together limit the rotation of the second unlocking member; or, in this case, the third housing may not be provided.

[0178] In some embodiments, as shown in FIG27, the second unlocking member is provided with at least one second limiting part. In the locked state, the second limiting part restricts the second unlocking member from rotating in the first direction so that the fifth elastic member generates a second pre-tightening force. That is, the setting of the second limiting part prevents the second unlocking member from rotating outward or in a direction away from the locking structure or the connecting hole.

[0179] For example, in some embodiments, as shown in Figure 27, the second limiting portion includes at least a limiting protrusion, which cooperates with the bottom of the first body to restrict the second unlocking member from rotating in the first direction; at the same time, as shown in Figure 57, the limiting protrusion is provided so that the bottom surface of the second unlocking member does not protrude from the bottom surface of the first body, that is, when the second unlocking member communicates with the outside through the third clearance opening 1001j, the bottom surface of the second unlocking member is not lower than the bottom surface of the first body, for example, the bottom surface of the second unlocking member is approximately flush with the bottom surface of the first body.

[0180] Alternatively, in other embodiments, as shown in Figures 26, 29, 31, 32, 56, and 57, the first body and the second unlocking member are both provided with a second limiting part, so as to accurately install the second unlocking member inside the first body.

[0181] In some embodiments, as shown in Figures 25 and 26, a first rotating shaft 700601 is provided on the second unlocking member, and the second unlocking member is hinged to the first body via the first rotating shaft. A fifth elastic member applies a spring force to the second unlocking member, forcing the second unlocking member to tend to stay away from the first limiting hole. A first motor is used to drive the second unlocking member to rotate, and the second unlocking member rotates into the first limiting hole to push the first locking member to move, causing the first locking member to exit the first limiting hole. For example, the fifth elastic member is a compression spring, one end of which is connected to the second unlocking member, and the other end is provided on the first body, in the first receiving cavity, or on the first dust chamber. The second unlocking member is subjected to a second preload force from the fifth elastic member and is located outside the first limiting hole. When the first motor removes the driving force on the second unlocking member, under the elastic action of the fifth elastic member, the second unlocking member returns to the outside of the first limiting hole. In some embodiments, the first motor is provided on the first body.

[0182] As shown in Figures 26 and 27, the second unlocking component includes a bent hinge arm 700602. The first pushing part 700603 of the second unlocking component is located at one end of the bent hinge arm 700602 facing the first locking component. The first force-receiving part 700606 of the second unlocking component is located at the other end of the bent hinge arm. The first rotating shaft is located between the first pushing part and the first force-receiving part. When the first force-receiving part is pushed by the power component, it rotates around the first rotating shaft, thereby pushing the first pushing part toward the first locking component to push the first locking component out of the first limiting hole, thereby unlocking the first bottom cover.

[0183] In some embodiments, a fifth elastic element is disposed between the first pushing portion and the first force-receiving portion of the second unlocking member. For example, in one embodiment, as shown in Figures 26 and 28, the fifth elastic element is disposed between the first pushing portion and the first rotating shaft, and the fifth elastic element is a compression spring; in another embodiment, the fifth elastic element is disposed between the first rotating shaft and the first force-receiving portion, and the fifth elastic element is a tension spring.

[0184] In some embodiments, as shown in Figures 25 and 26, the fifth elastic member is connected to the bent hinge arm and / or the first dust chamber via a fixing device. For example, the fixing device includes a first protrusion 700341 and a second protrusion 700342. One end of the fifth elastic member is connected to the bent hinge arm via the first protrusion, and the other end is limited to the second protrusion on the outer wall of the first dust chamber. When the first force-bearing part is not pushed by the power member, the bent hinge arm returns to its original position under the action of the fifth elastic member, thereby moving the first force-bearing part away from the first locking member. The first locking member returns to its original position under the action of the fourth elastic member and locks the first bottom cover.

[0185] In some embodiments, as shown in Figures 31 and 32, the unlocking assembly further includes a mounting member 70070 for fixing the first rotating shaft. The mounting member is fixed to the first body; for example, the mounting member 70070 is fixed to the outside of the first dust chamber, and the first rotating shaft is rotatably mounted on the mounting member. In some embodiments, to enhance the fixing effect of the first rotating shaft, the mounting member is provided with a plurality of reinforcing ribs 70071.

[0186] In some embodiments, as shown in FIG31, the mounting component is integrally disposed with the third housing; in other embodiments, as shown in FIG32, the mounting component is separately disposed with respect to the third housing.

[0187] In some embodiments, as shown in Figures 5 and 6, the first body includes at least a first receiving cavity 10013, a second receiving cavity 10522, and at least one communicating hole 10521. At least a portion of the first filter box is disposed in the first receiving cavity. The second receiving cavity is separated from the first receiving cavity by the wall of the first dust chamber 1052, and the communicating hole connects at least the first receiving cavity and the second receiving cavity. As shown in Figures 7, 9, and 10, or Figures 24, 25, and 26, in the locked state, the first pushing part of the second unlocking member does not extend into the first receiving cavity; furthermore, at least a portion of the first pushing part of the second unlocking member is located in the communicating hole. As shown in Figures 11, 12, and 13, or Figures 27, 28, and 29, during the unlocking process, at least a portion of the first pushing part of the second unlocking member extends into the first receiving cavity and into the first limiting part. For example, when the first bottom cover is locked, the first locking member is located inside the first limiting hole, meaning the first locking member does not extend outside the first limiting hole. If the first locking member extends outside the first limiting hole, it may interfere with the interior of the first dust chamber, thus affecting the removal and placement of the first filter box. Alternatively, at least part of the first locking member extends from the first limiting hole, but its extension distance does not interfere with the interior of the first dust chamber, thus not affecting the removal and placement of the first filter box. As shown in Figures 8 and 28, after unlocking, the first bottom cover flips downwards and is opened.

[0188] Further, as shown in Figures 1, 5, 9, and 26, a first dust chamber 1052 is provided within the first main body 1001. The first dust chamber has a first receiving cavity 10013, and a first filter box is disposed within the first receiving cavity. A second unlocking member is slidably or rotatably disposed on the first dust chamber, and at least the first force-bearing part of the second unlocking member is located outside the first dust chamber, receiving the drive of the first motor. Further, a connecting hole 10521 is provided on the first dust chamber for the second unlocking member to extend into or rotate into the first limiting hole, or to exit from or rotate away from the first limiting hole. As shown in Figures 9-11 (extending in) and 25-27 (rotating), when the locking structure is unlocked, the second unlocking member extends into or rotates into the connecting hole, and then extends into the first limiting hole to push the first locking member out of the first limiting hole.

[0189] In some embodiments, when the first filter box is placed inside the first dust chamber, the unlocking mechanism is located outside the first dust chamber. For example, the second unlocking member is located outside the connecting hole, that is, the second unlocking member is located on the side of the connecting hole away from the first limiting hole; or, as shown in FIG10 or FIG26, the second unlocking member is located inside the connecting hole but does not protrude into the first dust chamber. At this time, the second unlocking member is in the initial position, that is, it does not protrude from the connecting hole to affect the removal and placement of the first filter box inside the first dust chamber.

[0190] It should be noted that the second unlocking component can also be located inside the first dust chamber, as long as it does not affect the removal and placement of the first filter box.

[0191] In other embodiments, a first locking member is rotatably disposed on one of the first bottom cover and the first frame, and a first limiting hole is disposed on the other of the first bottom cover and the first frame. Under the elastic force generated by the fourth elastic member, the locking end of the first locking member tends to remain inserted into the first limiting hole, locking the first bottom cover onto the first frame. In this embodiment, the fourth elastic member can be a torsion spring or a compression spring; alternatively, it can also be a tension spring. Correspondingly, the second unlocking member can push the first locking member to rotate through the aforementioned telescopic movement or rotation, causing the locking end of the first locking member to exit the first limiting hole, thereby unlocking the first locking member.

[0192] When the first bottom cover is rotatably mounted on the first frame, in some embodiments, as shown in FIG33, the first bottom cover is driven to rotate by the first motor 70035. The first motor is mounted on the first body. After the first filter box is removed from the first receiving cavity, the first bottom cover is disconnected from the drive connection of the first motor. When the first filter box is placed into the first receiving cavity, a drive connection is established between the first bottom cover and the first motor.

[0193] Furthermore, in this embodiment, in the first state, the pool robot is stationary on the base station, and the first motor is at least used to drive the first bottom cover to move to open the third opening, so that the waste in the first filter box can be discharged from the third opening into the second filter box of the base station. Further, in some embodiments, in the first state, when the pool robot is stationary on the base station, the first motor is also at least used to drive the first bottom cover to move to close the third opening. For example, after the first nozzle finishes cleaning the first filter box, the first motor needs to drive the first bottom cover towards the third opening to close it, thus achieving automatic closure of the third opening by the first bottom cover.

[0194] For example, as shown in Figure 33, the pool robot also includes a second transmission component, a third transmission component, and a first motor 70035. For example, the second transmission component includes at least one third gear 105921; the third transmission component includes at least one fourth gear 105922. The first motor and the third gear 105921 are mounted on the first main body. For example, the third gear is mounted on the output shaft of the first motor. The fourth gear 105922 is connected to the first bottom cover. For example, the fourth gear is mounted on the rotation shaft of the first bottom cover. Furthermore, the second and third transmission components can also be other structures, such as belt drives, gear and rack drives, etc.

[0195] When the first filter cartridge is inserted into the first receiving cavity (i.e., the first filter cartridge is in its first state), the third gear and the fourth gear mesh. The first motor drives the third gear to rotate, which in turn drives the fourth gear to rotate, thereby rotating the first bottom cover (i.e., the first bottom cover and the first motor establish a driving connection), thus opening or closing the third opening. When the first filter cartridge is removed from the first receiving cavity, the third gear and the fourth gear disengage. The fourth gear, along with the first filter cartridge, is located outside the first main body (i.e., the first filter cartridge is in its second state), and the first motor disengages from the fourth gear. In this embodiment, the third gear and the fourth gear disengage during the removal of the first filter cartridge from the first receiving cavity.

[0196] Furthermore, in some other embodiments, when the first motor drives the first bottom cover to rotate, the pool robot can also use the self-locking force of the motor to keep the first bottom cover closed and the third opening closed. Alternatively, the self-locking force of the first motor and the locking mechanism work together to lock the first bottom cover onto the first frame.

[0197] In some embodiments, since the second and third transmission components are separated, in the second state, the third opening is closed by the user manually driving the first bottom cover. Further, in the second state, the first bottom cover moves under its own weight and / or the weight of the debris inside the first filter box to open the third opening.

[0198] In some embodiments, the pool robot further includes a locking mechanism that locks the first bottom cover to the first frame of the first filter box when the first bottom cover closes the third opening, so that the first bottom cover remains closed at the third opening; before the first bottom cover opens the third opening, the locking mechanism first releases the lock on the first bottom cover. When the locking mechanism releases the lock on the first bottom cover, that is, after the first bottom cover is unlocked, the first bottom cover can move relative to the first frame.

[0199] For example, in the second state, after the locking mechanism releases the first bottom cover from its lock, the first bottom cover moves under its own weight to open the third opening. Alternatively, in the second state, the locking mechanism can be manually activated by the user to release the first bottom cover from its lock.

[0200] In some embodiments, when the locking structure releases the lock on the first bottom cover, i.e., after the first bottom cover is unlocked, the first bottom cover can move relative to the first frame. At this time, the first bottom cover can open the third opening. Furthermore, after opening the third opening, the first bottom cover can also close the third opening under the action of a driving force. In some embodiments, the first bottom cover opens and closes the third opening under the driving force of a motor; or, in other embodiments, the first bottom cover opens the third opening without relying on the driving force of a motor, but closes the third opening under the driving force of a motor. For example, the first bottom cover rotates due to its own weight to open the third opening; or the first bottom cover rotates due to the weight of the first bottom cover, the garbage and liquid in the first filter box; or the first bottom cover rotates due to the weight of the first bottom cover, the garbage and liquid in the first filter box, and the impact force of the liquid sprayed by the first nozzle to open the third opening. Or, in another embodiment, the opening and closing of the third opening of the first bottom cover does not rely on a motor.

[0201] In some embodiments, when a locking mechanism 1080 is provided on the first bottom cover, the locking mechanism includes the aforementioned first locking member, fourth elastic member, and first limiting hole. For example, as shown in Figures 10, 11, 12, and 13, a first extension portion 10536 extending downward is provided on the first frame, and the first limiting hole is provided on the first extension portion. When the first bottom cover needs to close the third opening, the closing mechanism drives the first bottom cover to rotate toward the third opening. When the first locking member reaches the first extension portion and is located below the first limiting hole, the first extension portion squeezes the first locking member to retract, allowing the first bottom cover to continue rotating toward the third opening. When the first locking member rotates to the first limiting hole, the first extension portion releases its squeezing action on the first locking member. Under the action of the fourth elastic member, the first locking member extends to insert into the first limiting hole, thereby locking the first bottom cover.

[0202] In some embodiments, when the first bottom cover is rotatably mounted on the first frame, the first filter box further includes at least one torsion spring (not shown in the figure). The torsion spring is sleeved on a first pivot of the first bottom cover, with one end of the torsion spring acting on the first bottom cover and the other end acting on the first body or the first frame. Under the action of the torsion spring, the first bottom cover tends to close the third opening. In other embodiments, the pool robot may also be equipped with both a torsion spring and a locking mechanism.

[0203] In other embodiments, the aforementioned first motor and second transmission member are disposed on the first frame. In a first state, the first motor, second transmission member, and third transmission member are all located inside the first main body along with the first filter box; in a second state, the first motor, second transmission member, and third transmission member are all located outside the first main body along with the first filter box. That is, the drive assembly is disposed on the first filter box, and the drive assembly is synchronously inserted into the first main body and removed from the first main body along with the first filter box and located outside the first main body.

[0204] In this embodiment, in the second state, the drive component drives the first bottom cover to move, switching between opening and closing the third opening. In the first state, the pool robot is stationary on the base station, and the drive component drives the first bottom cover to move, switching between opening and closing the third opening. Further, in some embodiments, the pool robot also includes the aforementioned locking mechanism, which releases the lock on the first bottom cover before the third opening is opened.

[0205] In some embodiments, when the locking mechanism extends or rotates, it locks the first bottom cover onto the first frame; correspondingly, as shown in Figures 34, 35, 41, and 45, the unlocking mechanism 7003 includes a first motor and an unlocking component. The first motor drives the unlocking component to move, thereby pushing the locking mechanism to retract or rotate, forcing the locking mechanism to release the lock on the first bottom cover.

[0206] For example, the locking mechanism extends in the sixth direction to lock the first bottom cover onto the first frame; correspondingly, the unlocking component pushes the locking mechanism retract in the sixth direction, forcing the locking mechanism to release the lock on the first bottom cover. For example, the sixth direction is a horizontal or vertical direction, or other directions that intersect both the horizontal and vertical directions.

[0207] In some embodiments, both the first motor and the unlocking component are located within the first body of the pool robot; or, in other embodiments, both the first motor and the unlocking component are located on the base station body. Alternatively, in some embodiments, the first motor is located on the base station body, at least a portion of the unlocking component is located on the base station body, and at least a portion of the unlocking component is located within the first body.

[0208] For example, in some embodiments, when the locking mechanism includes the aforementioned first limiting hole, first locking member, and fourth elastic member; and the unlocking component includes the aforementioned second unlocking member, fifth elastic member, second mating member, and first unlocking member; the first motor and first unlocking member are disposed on the base station body; and the second unlocking member, fifth elastic member, and second mating member are disposed within the first main body. Alternatively, when the unlocking component does not include the aforementioned second mating member, the first motor 70035 and first unlocking member are disposed on the base station body, and the second unlocking member and fifth elastic member are disposed within the first main body.

[0209] In some embodiments, as shown in Figures 34, 35, and 36, the first unlocking member and the first motor 70035 are disposed in the base station body, and at least one fifth clearance opening 70036 is provided on the base station body. For example, the fifth clearance opening is provided on the stopping surface at the top of the base station body.

[0210] When the first motor 70035 drives the first unlocking member to move upward, at least a portion of the first unlocking member extends out of the base station body through the fifth clearance opening, driving the second mating member to move upward or driving the second unlocking member to rotate; when the first motor drives the first unlocking member to move downward, at least a portion of the first unlocking member retracts to its initial position inside the base station body through the fifth clearance opening. For example, in some embodiments, both the first unlocking member and the first motor are located within the sixth receiving cavity, and the fifth clearance opening is located on the top surface of the base station body and is near or around the fourth opening. For example, the fifth clearance opening is located on the first upper shell and is distributed away from the fourth opening.

[0211] In one embodiment, as shown in Figures 34 to 48, the first unlocking member 70031 is a first unlocking rod 70037. The first unlocking rod is vertically and flexibly mounted on the base station body, such that the first unlocking rod has at least a first position and an initial position. When the first unlocking rod is in the first position, it extends from the base station body and pushes the second mating member to move upward, causing the first locking member to disengage from the first limiting hole. When the first unlocking rod is in the initial position, it retracts into the base station body and no longer contacts the second mating member, releasing its force on the second mating member. Alternatively, in another embodiment, when the first unlocking rod is in the initial position, it retracts into the base station body, with the top of the first unlocking rod approximately flush with the resting surface of the base station body. At this time, the first unlocking rod still contacts the second mating member, but it does not exert any force on the second mating member.

[0212] Alternatively, when the first unlocking lever is in the first position, the first unlocking lever extends from the base station body and pushes the mating end of the second unlocking member, causing the second unlocking member to rotate so that the first locking member exits the first limiting hole; when the first unlocking lever is in the initial position, it retracts into the base station body and no longer applies force to the mating end of the second unlocking member.

[0213] In other embodiments, the first unlocking lever is fixedly mounted on the base station body. The first unlocking lever only has a first position. In this embodiment, when the pool robot is placed in the cleaning position, the first unlocking lever abuts against the second mating member to push the second mating member to move upward, so that the first locking member disengages from the first limiting hole. When the pool robot is moved away from the cleaning position, the first unlocking lever disengages from the second mating member. Furthermore, the first unlocking lever can be set to any shape, and no limitation is made here.

[0214] In other embodiments, the unlocking component does not include the aforementioned second telescopic member, fifth elastic member, and second mating member; the first unlocking member acts directly on the first locking member to drive the first locking member out of the first limiting hole. For example, the first motor 70035 drives the first unlocking member to extend along the sixth direction to drive the first locking member to retract in the sixth direction, thereby enabling the first locking member to exit the first limiting hole.

[0215] In some embodiments, as shown in Figures 35-48, the unlocking assembly further includes at least one sliding seat 70038. The sliding seat is disposed on the base station body, and the first unlocking member is slidably disposed on the sliding seat. The sliding seat guides the extension or retraction movement or lifting movement of the first unlocking member, enabling the first unlocking member to accurately push the second mating member to move, push the first locking member to retract, or push the second unlocking member to rotate, thereby improving the accuracy of the unlocking mechanism in unlocking the locking mechanism. In some embodiments, the sliding seat is integrally disposed with the base station body; or, in other embodiments, the sliding seat is separately disposed from the base station body.

[0216] In some embodiments, as shown in Figures 36 and 39, the sliding seat is provided with a limiting hole 70038a, and the first unlocking rod 70037 moves within the limiting hole 70038a to guide the lifting and lowering of the first unlocking rod. The limiting hole is at least connected to the fifth clearance opening.

[0217] In some embodiments, as shown in Figures 43 and 46, the first unlocking rod is provided with a limiting ring 70037a, and a limiting hole is located above the limiting ring. The outer diameter of the limiting ring is larger than the inner diameter of the limiting hole. Therefore, by cooperating with the limiting ring through the limiting hole, the first unlocking rod can be prevented from completely sliding out of the limiting hole during the upward movement. The sliding seat can be configured in various shapes, without specific limitations.

[0218] In one embodiment, as shown in Figures 40, 41, 44, and 45, the sliding seat can be disposed on the resting surface at the top of the base station body. In this case, at least a portion of the first unlocking rod is located within the base station body and at least a portion is located within the sliding seat. In this embodiment, when the first unlocking rod is in the first position, it extends from within the sliding seat, pushing the second unlocking member to rotate or the second mating member to slide, thereby causing the first locking member to exit the first limiting hole. When the first unlocking rod is in the initial position, it retracts into the sliding seat and does not contact the second unlocking member or the second mating member, releasing its force on the second unlocking member or the second mating member. Alternatively, in another embodiment, when the first unlocking rod is in the initial position, it retracts into the sliding seat, with the top of the first unlocking rod approximately flush with the top of the sliding seat.

[0219] Alternatively, in another embodiment, as shown in Figures 34, 35, 37, and 38, a sixth receiving cavity 2020 is provided on the base station body, and the sliding seat can be disposed in the sixth receiving cavity. In this case, since the sliding seat is disposed within the base station body, the first unlocking rod is located within the base station body. Alternatively, in another embodiment, the sliding seat is disposed on the resting surface at the top of the base station body and in the sixth receiving cavity to further ensure the stability of the movement of the first unlocking rod.

[0220] As shown in Figures 34-46, two unlocking levers 70037 can be configured, symmetrically arranged on opposite sides of the fourth opening; one first unlocking lever can also be configured, located on one side of the fourth opening, for example, in the middle of one side of the fourth opening. The position and number of the first unlocking levers are matched with the locking mechanism.

[0221] For the base station body, the base station body is the shell of the base station. For example, in some embodiments, as shown in FIG53, the base station body includes a second upper shell 20001a, a plurality of second side shells 20001b, and a second bottom shell 20001c. The top of the second side shell is connected to the second upper shell, the bottom of the second side shell is connected to the second bottom shell, and adjacent two second side shells are connected to form a cavity with an opening in one side wall. Further, to form the aforementioned third receiving cavity 2054, the base station body also includes a second dust chamber, which is disposed in the cavity, and the inner cavity of the second dust chamber serves as the third receiving cavity 2054; the second upper shell has a fourth opening that communicates with the third receiving cavity. Alternatively, in another embodiment, the second dust chamber can be replaced by a partition.

[0222] Furthermore, in some embodiments, to form the aforementioned sixth receiving cavity 2020, as shown in Figures 35, 47, 48, and 53, the base station further includes at least one mounting plate 200013. The mounting plate is disposed within the cavity, and a sixth receiving cavity is formed between the mounting plate 200013 and at least a portion of the second upper shell and a portion of the second side shell. At least a portion of the sixth receiving cavity is located above the third receiving cavity. Correspondingly, a portion of the fourth opening 2055 (i.e., the sewage inlet channel) is disposed on the second upper shell, and a portion of the fourth opening is disposed on the mounting plate to form an opening with a certain height or thickness. For example, in some embodiments, a mounting step is provided inside the second dust chamber, and the mounting plate is disposed on the mounting step to place the mounting plate within the cavity.

[0223] In some embodiments, as shown in Figures 47, 48, and 53, the first motor is disposed within the sixth receiving cavity 2020. For example, the first motor can be directly mounted on the mounting plate; or, the top of the mounting plate is provided with a mounting groove 20201, and the first motor is disposed within the mounting groove. In some embodiments, as shown in Figures 35 and 38, two first motors are symmetrically distributed on opposite sides of the fourth opening.

[0224] In some embodiments, the drive assembly further includes at least one first transmission assembly, through which the first motor and the first unlocking member are connected. The first motor drives the first transmission assembly to rotate, thereby driving the first unlocking member to move upward, thereby directly or indirectly pushing the first unlocking member to push the locking mechanism to move backward or rotate, forcing the locking mechanism to release the lock on the first bottom cover.

[0225] For example, in some embodiments, as shown in Figures 49-52, the first transmission assembly includes at least a first transmission member, which has at least one eccentric portion. For instance, the transmission member is a cam 70039, which has at least one second protrusion 70040. This second protrusion serves as the eccentric portion. A first motor drives the forward-facing wheel to rotate. When the second protrusion abuts against the first unlocking member, it pushes the first unlocking member upwards, causing the first unlocking member to move the second mating member, or the first locking member, or the second unlocking member to rotate, ultimately causing the first locking member to retract and exit the first limiting hole. When the first motor drives the cam to rotate in the opposite direction, after the second protrusion separates from the first unlocking member, the first unlocking member descends. Here, one of the forward and reverse directions is clockwise, and the other is counterclockwise.

[0226] In some embodiments, as shown in FIG55, since the garbage and liquid in the first filter box enter the second filter box through the third opening, the fourth opening, and the third inlet, the garbage in the second filter box tends to accumulate at or below the fourth opening (for example, the garbage accumulates into a small hill). The garbage accumulated at the fourth opening makes it difficult for the garbage in the first filter box to fall into the second filter box.

[0227] In some embodiments, the base station further includes a closing mechanism; in the first state, the pool robot is stationary on the base station, and the closing mechanism on the base station drives the first bottom cover to move, causing the first bottom cover to close the third opening. Further, in some embodiments, in the first state, the first bottom cover moves under at least its own weight and / or the weight of the debris in the first filter box, causing the first bottom cover to open the third opening.

[0228] For example, in one embodiment, the closing mechanism includes a drive member and at least one pusher member. The drive member drives the pusher member to move, and the pusher member pushes the first bottom cover toward the third opening, causing the first bottom cover to close the third opening. For example, the drive member is a motor. Alternatively, the pusher member is a push rod, and the motor drives the push rod to perform extension and retraction movements. The extension movement can be linear or non-linear. For example, the extension movement of the push rod includes linear motion and rotation.

[0229] Furthermore, in some embodiments, the pool robot includes the aforementioned locking mechanism. In the first state, the pool robot is stationary on the base station; the locking mechanism is released from locking the first bottom cover by being driven by the unlocking mechanism on the base station. This achieves the function of the base station automatically unlocking the locking mechanism.

[0230] For example, in the first state, the pool robot is stationary on the base station. The unlocking mechanism on the aforementioned base station drives the locking mechanism to move, thereby releasing the lock on the first bottom cover. The first bottom cover then rotates under its own weight and / or the weight of the debris inside the first filter box, thereby opening the third opening. Similarly, in the second state, after the locking mechanism releases the lock on the first bottom cover, the first bottom cover rotates under its own weight and / or the weight of the debris inside the first filter box, thereby opening the third opening.

[0231] In some embodiments, in the second state, the first bottom cover moves under the manual drive of the user to close or open the third opening. This allows the user to choose to open or close the third opening as needed.

[0232] In some embodiments, when the pool robot includes a locking mechanism, during the transition of the first filter box from a first state to a second state, the locking mechanism keeps the first bottom cover closed over the third opening. This ensures that during the removal of the first filter box from the first body, the first bottom cover remains closed over the third opening, preventing debris from falling out of the first filter box.

[0233] In some embodiments, while the first nozzle is spraying liquid into the first filter box, the first bottom cover remains closed with the third opening closed. The liquid sprayed by the first nozzle is located inside the first filter box, increasing the weight of the liquid inside the first filter box. This allows the first bottom cover to rotate rapidly under its own weight and the weight of the liquid in the first filter box to open the third opening.

[0234] In other embodiments, during the process of the first nozzle spraying liquid into the first filter box, the first bottom cover opens the third opening to facilitate the rapid discharge of waste from the first filter box.

[0235] In some embodiments, in a first state, when the pool robot is stationary on the resting surface and the first bottom cover opens the third opening, at least a portion of the first bottom cover extends into the fourth opening. The third opening and the fourth opening are connected so that the waste in the first filter box can quickly pass through the fourth opening into the second filter box.

[0236] Therefore, in some embodiments, the base station further includes at least one actuating mechanism, which is movably disposed on the base station body and at least partially located inside the second filter box. The actuating mechanism is used to actuate the garbage accumulated in the second filter box to spread or flatten the accumulated garbage, evenly disperse the garbage in the inner cavity of the second filter box, improve the space utilization rate inside the second filter box, avoid garbage accumulation below the fourth opening, and ensure that the garbage in the first filter box falls smoothly into the second filter box.

[0237] In some embodiments, as shown in Figures 47, 48, and 49, the agitating mechanism includes a third motor and an agitating assembly 70061. At least a portion of the agitating assembly 70061 is located within the second filter box. The agitating assembly is used to agitate or flatten the waste in the second filter box. The third motor drives the agitating assembly 70061 to reciprocate or move reciprocally within the second filter box, enabling the agitating assembly to agitate the waste in both directions, facilitating rapid flattening of the waste.

[0238] In some embodiments, the lever mechanism further includes at least one second transmission component, and a third motor is connected to the second transmission component. Driven by the third motor, the second transmission component is driven to reciprocate the lever.

[0239] In other embodiments, when the base station includes the aforementioned first motor and first unlocking member, the third motor used to drive the toggle assembly to move and the first motor used to drive the first unlocking member to move are the same motor. That is, the same first motor drives the lever to swing back and forth, and at the same time can drive the first unlocking member to move upward, so as to drive the first locking member to exit from the first limiting hole. Specifically, the aforementioned first transmission assembly and second transmission assembly are also the same transmission assembly.

[0240] For example, as shown in Figures 45, 47, and 49, when the lever mechanism and the unlocking mechanism share a single motor, the lever mechanism includes at least one lever 70062. The lever 70062 is connected to a first transmission assembly or a second transmission assembly, for example, to an eccentric portion (cam). The first motor or a third motor drives the first transmission assembly or the second transmission assembly to rotate, thereby causing at least a portion of the lever to reciprocate within the second filter box, thus agitating the debris within the second filter box. In this embodiment, the lever has at least an initial position and an unlocked position; in the unlocked position, as shown in Figures 49 and 50, the eccentric portion abuts against the first unlocking member; in the initial position, as shown in Figures 51 and 52, the eccentric portion separates from the first unlocking member.

[0241] In some embodiments, the structure disposed on the first body may be exposed on the surface of the first body or disposed inside the first body; furthermore, it may be disposed directly on the first body or indirectly on the first body, for example, it may be disposed on a structure that remains relatively stationary with respect to the first body.

[0242] In some embodiments, the lever mechanism, unlocking mechanism, and closing mechanism can be configured as detachable modular structures. For example, the unlocking mechanism can be integrated into a whole to form a modular structure, enabling modular assembly. This allows the unlocking mechanism to be assembled into individual modules before installation, and then installed on the base station and / or pool robot. This facilitates installation and disassembly, and is convenient for production. At the same time, it also makes it easy to disassemble or replace parts during after-sales maintenance.

[0243] When the pool robot stops on the base station and needs to clean the first filter box, the controller first controls the second baffle on the second inlet to open, and the first nozzle extends into the first filter box. Then, the controller controls the first nozzle to spray liquid into the first filter box for a preset duration. During this process, the first bottom cover of the first filter box keeps the third opening closed. After the first nozzle has sprayed for the preset duration, the controller controls the unlocking mechanism to unlock the locking mechanism of the first bottom cover. The first bottom cover opens under its own gravity and the gravity of the liquid and debris in the first filter box. The debris and liquid in the first filter box enter the second filter box in the third receiving cavity of the base station body through the third opening, thus completing the first cleaning of the first filter box by the first nozzle. The controller then controls the closing mechanism on the base station to close the third opening of the first bottom cover. The controller controls the first nozzle to withdraw from the first filter box, and then controls the second baffle to close the second inlet.

[0244] Alternatively, when the closing mechanism pushes the first bottom cover to close the third opening, and the first nozzle remains in the first filter box, the controller controls the first nozzle to perform a second cleaning of the first filter box. The cleaning process is the same as the first cleaning process, and will not be described in detail here.

[0245] During the multiple cleaning processes of the first nozzle on the first filter box, the first nozzle remains inside the first filter box. However, after each cleaning, the first nozzle needs to close the first bottom cover using a closing mechanism. After a preset cleaning time, the unlocking mechanism unlocks the locking mechanism of the first bottom cover, opening the third opening. After the required number of cleaning cycles, the controller retracts the first nozzle from the first filter box. Finally, the controller controls the second baffle to close the second water inlet, completing the entire cleaning process of the first nozzle on the first filter box.

[0246] During the process of the first nozzle spraying liquid onto the first filter box, a lever mechanism may operate to agitate debris in the second filter box. And / or, in other embodiments, when the first nozzle cleans the first filter box multiple times, the lever mechanism operates to agitate debris in the second filter box during the interval between the end of the previous cleaning of the first filter box and the beginning of the next cleaning.

[0247] When the lever mechanism and the unlocking mechanism are driven by the same motor, the controller controls the lever of the lever mechanism to move back and forth between the initial position and the unlocking position, but the lever will not reach the unlocking position. This prevents the lever mechanism from driving the first unlocking component to move upward during the process of the first nozzle spraying liquid into the first filter box, thereby unlocking the locking mechanism of the first bottom cover and opening the third opening of the first bottom cover.

[0248] If the lever mechanism and the unlocking mechanism are driven by different motors, their movements are independent, allowing the lever mechanism to be opened or closed at any time. For example, the controller may control the lever mechanism to operate during the liquid spraying process of the first nozzle, and / or during the aforementioned interval time period.

[0249] Alternatively, in some other embodiments, the first nozzle extends into the first filter box, and the controller first controls the unlocking mechanism to unlock the locking mechanism of the first bottom cover, so that the first bottom cover is opened; then the controller controls the first nozzle to spray liquid into the first filter box.

[0250] The detachable connection mentioned in this application is made by means of at least one of the following: threaded connection, magnetic connection, snap-fit ​​connection, key pin connection, locking connection, plug connection, grooved connection, screw connection, etc.

[0251] 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 pool water, 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. Alternatively, the base station is equipped with a support mechanism that automatically scoops the pool robot out of the pool and places it onto the base station body by rotating the support component.

[0252] 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.

[0253] 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.

[0254] 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.

[0255] 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.

[0256] 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.

[0257] 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.

[0258] 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.

[0259] 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.

[0260] 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.

[0261] 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.

[0262] 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.

[0263] 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.

[0264] 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.

[0265] 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.

[0266] 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.

[0267] 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 a high-speed water flow from the first nozzle. 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 it can increase the water flow velocity by reducing the diameter of the pipe adjacent to and connected to the first nozzle and / or reducing the orifice diameter at the water outlet.

[0268] In some embodiments, the pool robot can dock with the base station in the following ways: the pool robot docks with the base station underwater or on the water. The positional relationship between the pool robot and the base station when docking can be arranged horizontally or vertically. That is, when the pool robot is on the base station, it can lie on the base station body or carrier in a roughly vertical posture; or, it can be located on the base station body or carrier in a roughly horizontal posture.

[0269] For example, in some embodiments, the base station is located on the water, and at least a portion of the carrier is located underwater. When the base station docks with the pool robot, both the carrier and the pool robot are in a generally vertical position. At this time, the pool robot lies on the carrier to achieve docking between the base station and the pool robot, and the pool robot is located on the left or right side of the carrier. Alternatively, in another embodiment, the base station is located underwater, and when the base station docks with the pool robot, both the base station and the pool robot are in a generally horizontal position, and the pool robot is located above the base station body. Alternatively, in other embodiments, the base station is located on the water, and when the base station docks with the pool robot, both the base station and the pool robot are in a generally horizontal position, and the pool robot is located above the base station body.

[0270] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
