Detailed Implementation

[0088] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, so as to provide a thorough understanding of the embodiments of this disclosure. However, those skilled in the art will understand that this disclosure may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this disclosure with unnecessary detail.

[0089] like Figures 1 to 39As shown, an exemplary embodiment of this disclosure provides a pool robot 1000, which is used to perform tasks such as cleaning, disinfection, and rescue in a target area. The target area can be a water-containing area where the pool robot 1000 can move. For example, the target area may 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.

[0090] The pool robot can move or stay on the pool bottom. Alternatively, it can be below the water surface but its bottom does not contact the pool bottom, meaning it can float or move in the water. The pool robot can also be on the pool wall, meaning it can climb or stay against the wall. Finally, it can float on the water surface. For example, at least part of the pool robot may be above the water surface and at least part below, allowing it to move or remain still on the surface.

[0091] In some embodiments, such as Figures 35 to 39 As shown, the pool robot 1000 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 pool liquid to enter the first body 1001, enabling the robot to clean at least one of the pool bottom, pool walls, waterline, and water surface. The liquid outlet is used to discharge the liquid filtered by the first filter assembly out of the first body. The suction assembly generates suction force to guide the liquid flow. The first filter box filters the dust-laden water, leaving debris inside. Under the action of the suction assembly, dust-laden water in the pool is drawn into the first filter box through the liquid inlet, filtered, and debris remains inside. The filtered liquid, after passing through the suction assembly, is finally discharged out of the first body through the liquid outlet. The first body constitutes the outer shell structure of the pool robot, which can be made of waterproof material and contains necessary components such as a drive mechanism, control board, and suction assembly.

[0092] In one embodiment, such as Figures 35 to 38As shown, the liquid inlet section includes at least a first inlet 1031, the liquid outlet section includes at least one first outlet 1041, and the suction assembly includes a main water pump 1061. The first inlet 1031, the first filter box 1051, the main water pump 1061, and the first outlet 1041 are sequentially fluidly connected to form a first water path for cleaning the bottom wall, side wall, or waterline of the pool. For example, in one embodiment, there is one first outlet. Alternatively, in other embodiments, there are multiple first outlets; for example, there are two, three, or more first outlets.

[0093] In other embodiments, such as Figures 35 to 39 As shown, 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 connected in sequence to form a second water channel for cleaning the water surface and water line.

[0094] In other embodiments, the liquid inlet includes at least the aforementioned first water inlet and second water inlet.

[0095] For the first inlet, in some embodiments, such as Figure 37 and Figure 38 As shown, the first water inlet 1031 is located at the bottom of the first main body 1001. Correspondingly, as... Figure 2 , Figure 4 As shown, the first filter box is provided with a first inlet 10511a, which communicates with a first water inlet 1031, so that liquid in the pool enters the first filter box 1051 through the first water inlet 1031 for filtration. In other embodiments, such as Figures 1 to 4 As shown, the first filter box is provided with a second inlet 10511b, which is connected to the second water inlet 1032 so that the liquid on the surface of the pool water enters the first filter box 1051 through the second water inlet 1032 for filtration.

[0096] For example, the first inlet is located at the bottom of the first filter box to allow liquid from the water tank to enter the first filter box, and the first inlet is connected to the first water inlet; further, the first inlet is located on the first bottom cover (mentioned later); or, the first inlet is located at the bottom of the first frame (mentioned later) and does not move with the first bottom cover.

[0097] For example, a second inlet is located on the side of the first frame to allow liquid from the pool to enter the first filter box, and the second inlet is connected to the second water inlet. In some 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, facilitating the direct entry of pool liquid into 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.

[0098] In other embodiments, such as Figure 9 and Figure 10 As shown, the first inlet is located at the bottom of the first filter box, with the bottom of the first filter box 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 one opening; or, the bottom of the first filter box has a first protrusion 10523 extending into the first filter box. The first protrusion is hollow to form a liquid inlet channel. The lower end 105232 (or outer end) of the liquid inlet channel serves as the first inlet, and the upper end 105231 (or inner end) of the liquid inlet channel serves as the first entrance, so that liquid in the pool enters the first filter box through the first inlet and the first entrance. The first protrusion moves synchronously with the first base to open or close the third opening (mentioned later). Alternatively, the entire liquid inlet channel can be used as the first inlet or the first entrance.

[0099] It should be noted that: the bottom of the first filter box being exposed above the first main body or communicating with the outside means that when the third opening of the first bottom cover is closed, the bottom wall of the first bottom cover is flush with the bottom wall of the first main body; or the bottom wall of the first bottom cover protrudes downward beyond the bottom wall of the first main body (i.e., in the height direction of the pool robot, the bottom wall of the first bottom cover is lower than the bottom wall of the first main body); or the bottom wall of the first bottom cover is recessed relative to the bottom wall of the first main body (i.e., in the height direction of the pool robot, the bottom wall of the first bottom cover is higher than the bottom wall of the first main body).

[0100] In other words, when the third opening is closed by the first bottom cover, the user can see the bottom wall of the first bottom cover from the bottom of the pool robot. The bottom wall of the first bottom cover, as part of the bottom wall of the pool robot, is exposed to the external environment. The bottom wall of the pool robot includes at least the bottom wall of the bottom shell, the bottom wall of the first bottom cover, the walking surface of the walking mechanism (e.g., the walking surface of the track), the bottom wall of the main roller brush, etc.

[0101] In some embodiments, such as Figure 35 , Figure 36 and Figure 39As shown, the first main body includes a first receiving cavity 10013 and a second receiving cavity 10014, which are separated. A second drain port 10013a is provided on the side wall of the first receiving cavity, connecting the first and second receiving cavities. At least a portion of the first filter box is located in the first receiving cavity; the main water pump is located in the second receiving cavity, and the first water outlet is connected to the second receiving cavity. Thus, the first water inlet, the first filter box, the first receiving cavity, the second drain port, the main water pump, and the first water outlet are sequentially fluidly connected to form a first water path.

[0102] Furthermore, in other embodiments, such as Figure 35 , Figure 36 and Figure 39 As shown, the second receiving cavity 10014 includes a first cavity 10014a and a second cavity 10014b, wherein the first cavity and the second cavity are separated. A second drain port 10013a connects the first receiving cavity and the first cavity, and a first outlet 1041 is provided on the first main body and communicates with the first cavity. The main impeller of the main water pump is located in the first cavity 10014a, and the main motor of the main water pump is located in the second cavity 10014b. The first outlet communicates with the first cavity, and the second drain port connects the first receiving cavity and the first cavity, so that the first inlet, the first filter box, the first receiving cavity, the second drain port, the main impeller in the first cavity, and the first outlet are sequentially fluidly connected to form a first water path. And / or, the second inlet, the first filter box, the first receiving cavity, the second drain port, the main impeller in the first cavity, and the first outlet are sequentially connected to form the aforementioned second water path.

[0103] In some embodiments, such as Figures 35 to 39 As shown, the first main body is provided with a fourth inlet 1016, which is connected to the first filter box, allowing the first nozzle from the outside to extend into or exit the pool robot through the fourth inlet. Since the first nozzle can extend into the first main 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.

[0104] In some embodiments, such as Figures 35 to 39 As shown, the fourth inlet can be the first water inlet or the second water inlet; when the first body is provided with a pick-up and drop-off port, the fourth inlet can also be a pick-up and drop-off port, which is used for the user to put the first filter box into the first body or take out the first filter box from the first body; or, in some other embodiments, the fourth inlet can be independent of the first water inlet and the second water inlet, and the pick-up and drop-off port is provided on the first body.

[0105] In some embodiments, such as Figures 1 to 4As shown, the first filter box also includes an eleventh opening 10532, at least a portion of which is located on the top of the first filter box; as Figure 35 , Figure 36 as well as Figure 39 As shown, the pool robot also includes a pick-up / placement port 1017 and a first cover 1018. At least a portion of the pick-up / placement port is located on the top of the first main body and communicates with the first receiving cavity. The first cover is used to open or close the pick-up / placement port. The pick-up / placement port allows the user to place the first filter box into the first receiving cavity or remove the first filter box from the first receiving cavity. The eleventh opening communicates with the pick-up / placement port, facilitating the user to empty the waste in the first filter box through the eleventh opening. Furthermore, it allows the first nozzle to pass through the pick-up / placement port and the eleventh opening to extend into the first filter box and spray liquid to clean the first filter box when the first nozzle cleans it.

[0106] In some embodiments, the first cover 1018 is movably disposed on the first body. Further, the first cover is movably disposed at the retrieval port; for example, the first cover is slidably or rotatably disposed on the retrieval port. Alternatively, in some embodiments, the first cover is detachably disposed on the retrieval port. For example, when a user needs to remove the first filter box from the first body, the first cover must first be removed from the first body, and then the first filter box can be removed through the retrieval port. Alternatively, in other embodiments, the first cover 1018 is movably disposed on the first filter box, in which case the first cover acts as part of the top of the first body; for example, the first cover is slidably or rotatably disposed on the first filter box, meaning the first cover and the first filter box move simultaneously. For example, when a user needs to remove or place the first filter box from the first body, the first cover and the first filter box can be removed or placed together.

[0107] In other embodiments, such as Figures 1 to 4 As shown, the first filter box also includes a second handle 1057, which is disposed on the first frame to facilitate the user to place the first filter box into or remove it from the first receiving cavity by lifting the second handle.

[0108] In some embodiments, in order to discharge the waste from the first filter box, such as Figures 1 to 4 , Figure 35 and Figure 36 As shown, the first filter box includes at least one third opening 10531; and a first bottom cover 1054, which can open or close the third opening.

[0109] In some embodiments, at least a portion of the third opening is located on the bottom of the first filter box, facilitating the rapid discharge of waste and liquid from the first filter box under gravity. For example, in some embodiments, the bottom of the first filter box has a bottom opening, which serves as the third opening, and a first bottom cover is movably disposed on the third opening to open or close it. For example, the first bottom cover has an operating state with the third opening open and a non-operating state with the third opening closed.

[0110] It should be noted that the third opening 10531 can have different design forms to optimize waste discharge. Specifically, the third opening can occupy a portion or the entire area of ​​the bottom of the first filter box. For example, the third opening can occupy 1 / 2, 1 / 3, 3 / 4, or 4 / 5 of the bottom area of ​​the first filter box. The area occupied by the third opening can be determined according to the actual situation and is not specifically limited. Alternatively, in some embodiments, the third opening includes a first part and a second part, wherein the first part is located on the bottom of the first filter box and the second part is located on the side wall of the first filter box, for example, forming an L-shaped opening to further increase the size of the third opening of the first filter box, facilitating the discharge of large-sized waste from the first filter box. For example, in some embodiments, the third opening includes the aforementioned first part and at least two of the aforementioned second parts, for example, forming a U-shaped opening, thereby further increasing the size of the third opening. In the following embodiments, for ease of description, the example is taken where the third opening is located at the bottom of the first filter box; of course, it is also applicable to the scheme where at least a portion of the third opening is located on the side wall of the first filter box and at least a portion is located at the bottom of the first filter box.

[0111] In some embodiments, such as Figure 3 , Figure 16 , Figure 26 As shown, a first bottom cover is rotatably disposed at the third opening. Rotation of the first bottom cover opens or closes the third opening. For example, the first bottom cover is rotatably disposed at the third opening via a first rotating shaft 1054c. Alternatively, in other embodiments, the first bottom cover is slidably disposed at the third opening. Sliding of the first bottom cover opens or closes the third opening. For example, the first bottom cover is slidably disposed at the third opening via a screw structure, cylinder structure, gear and rack mechanism, or slide rail. Further, for example, the first bottom cover is translatably disposed at the third opening in the horizontal direction; or, the opening or closing of the third opening is achieved by sliding the first bottom cover in the inclined direction. Alternatively, in other embodiments, the first bottom cover is both rotatable and slidable at the third opening. Rotation and sliding of the first bottom cover open or close the third opening.

[0112] In some embodiments, such as Figures 1 to 4 As shown, 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; or, 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; or, at least a portion of the first filter screen is disposed on the side of the first frame to form a filter surface, thereby filtering the liquid entering the first filter box; the first bottom cover is movably disposed on the first frame, switching between opening and closing the third opening.

[0113] In some embodiments, such as Figures 1 to 4 As shown, the first frame includes a first side portion 105311, a second side portion 105312, a third side portion 105313 and a fourth side portion 105314, wherein the second side portion is opposite to the first side portion, and the first side portion, the third side portion, the second side portion and the fourth side portion are connected in sequence to form the first frame.

[0114] In the above embodiments, the first filter screen being disposed on the side of the first frame can be a fixed installation on the side of the first frame, for example, by means of bonding, welding, tensioning, or bolt tightening; alternatively, the first filter screen and the first frame can be sleeved together, for example, the first filter screen is sleeved outside the side of the first frame or embedded inside the side of the first frame. Both of these arrangements involve the first filter screen being disposed on the side of the first frame. When the first filter screen and the first frame are connected by a sleeve, the first filter screen can be made of flexible synthetic fibers, shapeable materials, or metal woven materials. For example, the material of the first filter screen can be non-woven fabric, filter cotton, foam, or stainless steel woven mesh.

[0115] In some embodiments, the first bottom cover is rotatably mounted on the first frame. For example, the first bottom cover opens the third opening when it rotates inward into the first frame; conversely, it closes the third opening when it rotates outward from the first frame towards the third opening. In this embodiment, when the first bottom cover opens the third opening, some waste will be blocked inside the first frame by the first bottom cover as it rotates into the inner cavity of the first filter box, making it difficult to discharge from the first filter box through the third opening.

[0116] Therefore, in other embodiments, the first bottom cover opens the third opening by rotating outward from the first frame, the pool robot, or the first body; conversely, the first bottom cover closes the third opening by rotating from outside the first frame towards the third opening. In this embodiment, when the third opening is open, since the first bottom cover is located outside the first frame, it will not block the debris in the first filter box, allowing the debris in the first filter box to be discharged from the third opening.

[0117] Alternatively, in other embodiments, the first bottom cover is slidably disposed on the first frame to switch between opening and closing the third opening.

[0118] For example, in some embodiments, such as Figure 35 As shown, the third opening 10531 is located at the bottom of the first filter box, as... Figure 6 , Figure 11 , Figure 12 As shown, the first bottom cover includes a first base 10541, which is used to open or close the third opening. When the first base opens the third opening, the garbage in the first filter box is discharged from the third opening out of the first filter box.

[0119] In some embodiments, such as Figure 38 As shown, a seventh opening 1033 is provided at the bottom of the first main body. In some embodiments, 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 waste to be discharged out of the pool robot, but also needs to avoid the movement of the first base; that is, the seventh opening serves as the first drain outlet for 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. Specifically, the first base rotates outward toward the first main body through the seventh opening to open the third opening; or, the first base rotates toward the third opening through the seventh opening to close the third opening.

[0120] In other embodiments, the seventh opening is located above 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 it 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. In this embodiment, the third opening serves as the first drain outlet for discharging waste from the first filter box from the pool robot.

[0121] In some embodiments, when at least a portion of the third opening is located on the bottom of the first filter box and a seventh opening 1033 is provided on the first main body, the first inlet is located on the bottom of the first main body, and a first inlet is also provided on the bottom of the first filter box. The first inlet and the first inlet are connected, and the liquid in the pool enters the first filter box sequentially through the first inlet and the first inlet. The first inlet and the third opening are staggered on the bottom of the first filter box. In this embodiment, the movement of the first base does not synchronously drive the movement of the first inlet and the first inlet, that is, the movement of the first base is independent of the first inlet and the first inlet.

[0122] In this embodiment, for the first water inlet and the seventh opening, in one embodiment, the first water inlet and the seventh opening are staggered and distributed in the first body, and the two are set independently; in other embodiments, the first water inlet and the seventh opening are combined into a large-sized opening, namely the eighth opening, part of the eighth opening is connected to the first inlet, and part of the eighth opening is connected to the third opening.

[0123] In other embodiments, at least a portion of the third opening is located on the bottom of the first filter box, and the first inlet is also located on the bottom of the first filter box, with the first inlet and the third opening offset from each other on the bottom of the first filter box. Pool liquid enters the first filter box through the first inlet. In this embodiment, although the first inlet is located on the bottom of the first filter box, the movement of the first base is independent of the first inlet and does not cause the first inlet to move synchronously.

[0124] In the aforementioned embodiments, since the first inlet or first water inlet is located on the bottom of the first filter box and is horizontally offset from the third opening, the first inlet or first water inlet occupies a portion of the bottom area of ​​the first filter box, making the area of ​​the third opening limited. This can cause large-sized debris in the first filter box to have difficulty falling into the second filter box from the third opening, or large-sized debris to get stuck at the third opening, affecting the cleaning effect of the first nozzle on the debris in the first filter box.

[0125] Therefore, in order to increase the area occupied by the third opening on the bottom of the first filter box and to discharge large debris from the first filter box, in some embodiments, the first bottom cover includes a first base 10541, and a first water inlet is provided on the first base. The first base moves to drive the first water inlet to move synchronously to open or close the third opening, thereby increasing the area of ​​the third opening at the bottom of the first filter box. The third opening can occupy all or most of the area of ​​the bottom of the first filter box, thereby increasing the area of ​​the third opening. This makes it easier for large debris in the first filter box to be discharged from the third opening when the first base opens the third opening, so that it can fall into the second filter box.

[0126] like Figures 35 to 38 As shown, when the first water inlet is located on the first base, it is equivalent to the first water inlet and the first inlet being combined into a single opening. Alternatively, as... Figure 6 , Figure 12 As shown, the first bottom cover also includes a first protrusion 10523, 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 lower end of the first protrusion serves as a first water inlet, and the upper 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.

[0127] For example, when the pool robot is placed on a horizontal surface, the vertical projection of the first water inlet on the horizontal surface is the first projection, and the vertical projection of the third opening on the horizontal surface is the second projection, with the first projection located within the second projection; or the third opening is located directly above the first water inlet, and the area of ​​the third opening is larger than the area of ​​the first water inlet. When the first bottom cover moves away from the third opening, the first bottom cover moves the first water inlet together to open the third opening, allowing large debris in the first filter box to fall into the second filter box of the base station. In some embodiments, when the pool robot stops at the cleaning position of the base station body, the first bottom cover rotates outward from the first body to open the third opening, and when the third opening is open, at least a portion of the first bottom cover extends into the second filter box.

[0128] In some embodiments, such as Figure 38 As shown, when the first water inlet is located on the first bottom cover, the first body is provided with a seventh opening 1033. The seventh opening is at least used to expose the bottom of the first bottom cover to the first body or to the external environment, to avoid the movement of the first bottom cover, and to open or close the third opening.

[0129] For example, in some embodiments, the third opening is higher than the seventh opening in the height direction of the pool robot. When the first bottom cover opens the third opening, the waste in the first filter box is discharged out of the first main body sequentially through the third opening and the seventh opening. The seventh opening serves as the first drain outlet for discharging waste from the first filter box out of the pool robot. Specifically, in some embodiments, at least a portion of the first bottom cover rotates out of the pool robot through the seventh opening to open the third opening; and at least a portion of the first bottom cover rotates back to the third opening through the seventh opening to close the third opening. In other embodiments, the first inlet is lower than or level with the seventh opening, and liquid in the pool enters the first filter box through the first inlet; or, in other embodiments, the first inlet is higher than the seventh opening, and liquid in the pool enters the first filter box through the seventh opening and the first inlet.

[0130] For example, in other embodiments, the third opening is lower than or flush with the seventh opening in the height direction of the pool robot; when the first bottom cover opens the third opening, the waste in the first filter box is discharged from the first main body through the third opening, which serves as the first drain outlet. Specifically, in some embodiments, the first bottom cover rotates below the seventh opening to open or close the third opening. Alternatively, in some embodiments, since the third opening is lower than or flush with the seventh opening, the first water inlet is located on the first bottom cover, and the liquid in the pool enters the first filter box through the first water inlet.

[0131] For example, in other embodiments, in the height direction of the pool robot, if the first water inlet is lower than or level with the seventh opening, the liquid in the pool enters the first filter box through the first water inlet; or, if the first water inlet is higher than the seventh opening, the liquid in the pool enters the first filter box through the seventh opening and the first water inlet.

[0132] In some embodiments, such as Figure 25 As shown, the first frame 1053 includes at least an upper section 1053a, a lower section 1053b, and a transition section 1053c. A second handle 1057 is provided on the upper section, a third opening is provided on the lower section, and the transition section connects the upper section and the lower section.

[0133] Furthermore, in some embodiments, such as Figure 25 As shown, the lower section 1053b is composed of at least a first sidewall 1053b1, a second sidewall 1053b2, a third sidewall 1053b3, and a fourth sidewall 1053b4, wherein the first sidewall, the third sidewall, the second sidewall, and the fourth sidewall are sequentially connected to form the lower section. In some embodiments, the first sidewall and the first bottom cover are rotatably connected via a first pivot.

[0134] In other embodiments, such as Figure 6 , Figure 12 As shown, the first bottom cover also includes at least one counterweight 1056, which is disposed on the first base to adjust the overall weight of the pool robot, making the center of gravity of the pool robot more stable. For example, in some embodiments, the counterweight is foam. When the first base faces the bottom of the pool, the foam makes the buoyancy of the first bottom cover greater than its weight, thereby allowing the first base to be pressed more firmly against the third opening.

[0135] In one embodiment, the counterweight is disposed on the bottom, top, or side wall of the first base; or the counterweight is disposed on the first base and at least partially surrounds at least a portion of the outer periphery of the first protrusion.

[0136] Alternatively, in other embodiments, such as Figure 6 , Figure 12As shown, the first bottom cover has a first mounting cavity 1054d, and at least one counterweight is disposed within the first mounting cavity. For example, the first bottom cover also includes a second base 10542, which is connected to the first base. The aforementioned first protrusion is connected to at least one of the first base and the second base, and a liquid inlet channel is formed within the first protrusion. The first base, the first protrusion, and the second base together form the first mounting cavity, and the counterweight is disposed within the first mounting cavity. For example, in some embodiments, the first mounting cavity is formed between the first base and the second base, and at least a portion of the first mounting cavity surrounds the outer periphery of the first protrusion.

[0137] In some embodiments, at least a portion of the second base is disposed around the outer periphery of at least a portion of the first protrusion, and at least a portion of the first base is disposed around the outer periphery of at least a portion of the first protrusion to expose the liquid inlet channel, such that when the first bottom cover closes the third opening, the lower end of the liquid inlet channel communicates with the outside, and the upper end communicates with the inner cavity of the first frame.

[0138] For example, in some embodiments, such as Figure 6 , Figures 10 to 12 As shown, the second base is located on the upper part of the first base, or in other words, the upper part of the first bottom cover includes the second base, that is, the second base and the first base are arranged vertically; or, in some other embodiments, the second base is located on the left or right side of the first base, that is, the second base and the first base are arranged horizontally.

[0139] In some embodiments, such as Figure 8 , Figure 9 As shown, the second base is located above the first base, and the upper end of the first protrusion passes through the second base and communicates with the outside; or, the second base is provided with a second communication port, and the upper end of the first protrusion is connected to the inner cavity of the first frame through the second communication port.

[0140] Furthermore, in some embodiments, such as Figure 8 , Figure 9 As shown, the lower end of the first protrusion passes through the first base and communicates with the outside; or, the first base is provided with a first communication port, and the lower end of the first protrusion communicates with the outside through the first communication port.

[0141] Alternatively, in some other embodiments, if the first mounting cavity is a sealed cavity, the counterweight can be a gas or liquid sealed therein. That is, the counterweight is located in the first mounting cavity, and the weight in the first mounting cavity can remain stable. The structure of the counterweight is not limited.

[0142] In some embodiments, at least one of the first base and the second base of the first bottom cover is used to close or open the third opening. In some embodiments, the first bottom cover closes and opens the third opening via the second base; for example, in some embodiments, such as Figures 5 to 12As shown, the second base covers or is disposed on the first base and surrounds the outer periphery of the first protrusion, and the second base closes or opens the third opening. That is, the second base presses against or seals the third opening to close it; the first bottom cover moves to move the second base away from the third opening to open it. Alternatively, in some embodiments, the first bottom cover closes and opens the third opening together through the first base and the second base; for example, in some embodiments, the second base is disposed above the first base, and the edge of the second base is located inside the edge of the first base, the first base and the second base together press against or seal the third opening to close it; the first base moves away from the third opening to open it.

[0143] In some embodiments, to ensure that the first or second base can seal the third opening when it is closed, a sealing gasket (e.g., a first shielding member) is provided on the first or second base. When the first or second base closes the third opening, the sealing gasket is pressed tightly against the third opening to seal it, allowing the liquid in the pool to enter the first filter box through the first inlet, instead of entering the dust box through the first gap 105a (or slit) between the first bottom cover and the third opening. If the dust-laden water from the pool flows into the dust box through the slit between the first bottom cover and the third opening, some debris will inevitably get stuck in this slit, affecting the opening or closing action of the first bottom cover.

[0144] The second base 10542 and the first base 10541 can have various mating relationships. For example, the second base 10542 can completely cover the upper surface of the first base 10541 like a cover, while simultaneously surrounding the first protrusion 10523. Alternatively, the second base 10542 can be mainly arranged around the outer periphery of the first protrusion 10523, forming a sandwich structure together with the first base 10541. Functionally, at least one of the first base 10541 and the second base 10542 has its edge portion designed to mate with the opening edge of the bottom frame of the first filter box 1051, thereby achieving the sealing or blocking function of closing or opening the third opening 10531.

[0145] In some embodiments, the first bottom cover is rotatably mounted on the third opening via a first pivot 1054c. In some embodiments, the first pivot is mounted on the first frame; in other embodiments, the first pivot is mounted on the first base or the second base; or in other embodiments, the first pivot is mounted on both the first base and the second base.

[0146] In some embodiments, when the first bottom cover is rotatably connected to the first frame, such as Figures 5 to 12As shown, the first bottom cover includes a first mounting portion 1054a and a first movable portion 1054b, and the first bottom cover is rotatably connected to the first frame via the first mounting portion. The first mounting portion is rotatably mounted on the first frame via a first rotating shaft 1054c, and the first movable portion rotates around the first rotating shaft to open or close the third opening.

[0147] In some embodiments, at least one of the first base and / or the second base is provided with a second fixing seat 1054h, and the first bottom cover is rotatably connected to the first frame through the second fixing seat. Further, in some embodiments, referring to... Figure 3 As shown, a second fixed seat is provided on the first mounting part, and a first fixed seat 1053d is provided on the first frame. A first rotating shaft is fixed on the first fixed seat, and a second fixed seat is rotatably provided on the first rotating shaft; or, the first rotating shaft is fixed on the second fixed seat, and the first fixed seat is rotatably provided on the first rotating shaft, so that the second fixed seat can rotate relative to the first fixed seat, thereby causing the first bottom cover to rotate relative to the first frame.

[0148] To maximize the space within the first filter box that can hold waste, in some embodiments, such as Figures 1 to 12 As shown, at least a portion of the upper part of the first bottom cover is provided with a first recess 1054e; when the first bottom cover is in the closed third opening state, a first recessed area is formed between the first recess and a portion of the bottom of the first frame (e.g., at least a portion of the lower section) for accommodating waste. Further, in some embodiments, the upper part of the first bottom cover includes a second base, and a portion of the second base forms a first recessed area between a portion of the bottom of the first frame (e.g., at least a portion of the lower section).

[0149] As the waste in the first filter box is discharged through the third opening, liquid may flow over or remain on the upper surface of the first bottom cover. Some waste may adhere tightly to or be attached to the upper surface of the first bottom cover, making it difficult for it to fall into the second filter box. For example, some waste may be leaves, which tend to adhere entirely to the upper surface of the first bottom cover.

[0150] Therefore, in other embodiments, such as Figure 6 and Figure 12 As shown, the first bottom cover includes at least one, two, or more first protrusions 105421a. The first protrusions protrude from the upper surface of the first bottom cover, with adjacent first protrusions spaced apart on the upper part of the first bottom cover and located within a first recess. When waste falls from the third opening, some of the waste lands on the upper surface of the first bottom cover. Due to the arrangement of the first protrusions, the upper surface of the first bottom cover forms an uneven surface, preventing the waste from completely adhering to the upper surface of the first bottom cover, thus allowing the waste to fall smoothly from the third opening into the second filter box. For example, the first protrusion can be a dot, a strip, a tooth, or a rib.

[0151] For example, in some embodiments, such as Figure 6 and Figure 12 As shown, the second base 10542 includes at least a first sub-base 105421 and a second sub-base 105422, which are distributed on both sides of the first protrusion or the liquid inlet channel. The first sub-base is closer to the first pivot of the first bottom cover than the second sub-base. In some embodiments, the first and second sub-bases are formed on the first protrusion; or, the first and second sub-bases are detachably disposed on the first protrusion; at least one of the first sub-base, the second sub-base, and the first protrusion is connected to the first base to form a first mounting cavity for the first bottom cover.

[0152] When the first bottom cover opens to the third opening, as Figure 6 , Figure 12 As shown, the first sub-base 105421 is located above the second sub-base 105422. During the process of the garbage in the first filter box being discharged from the first filter box through the third opening, liquid will flow over or remain on the upper surface of the first sub-base. Some garbage will stick to or adhere to the upper surface of the first sub-base, making it difficult to fall into the second filter box.

[0153] Therefore, in other embodiments, such as Figure 6 , Figure 12 As shown, at least two first protrusions 105421a are provided on the second base. The first protrusions protrude from the upper surface of the first sub-base. When the garbage falls from the third opening, some of the garbage falls on the upper surface of the first sub-base. Due to the setting of the first protrusions, the upper surface of the first sub-base forms an uneven surface, preventing the garbage from completely adhering to the upper surface of the first sub-base. Thus, the garbage can fall smoothly from the third opening into the second filter box.

[0154] In other embodiments, if the entire upper surface of the first sub-base is flush with the upper surface of the first protrusion, then the first sub-base and the first protrusion are located inside the first filter box, occupying a portion of the internal space of the first filter box, thus reducing the space available for waste to be contained within the first filter box. To solve this technical problem, the aforementioned first recessed area is formed between the first sub-base and a portion of the bottom of the first frame (e.g., at least a portion of the lower section) to accommodate waste. Further, in other embodiments, such as... Figure 6 , Figure 12 As shown, the first sub-base includes at least a first transition portion 105421b, and a first recessed area is formed between the first transition portion and a portion of the bottom of the first frame (e.g., at least a portion of the lower section). Further, two first protrusions 105421a are provided on the first transition portion 105421b.

[0155] In some embodiments, when the first bottom cover closes the third opening, the first transition portion is an inclined section; or, the upper surface of the first transition portion is an inclined surface, so that when the first bottom cover opens the third opening, the garbage can slide down along the inclined surface of the first transition portion, avoiding garbage residue on the first transition portion.

[0156] In other embodiments, to further increase the volume of the first recessed area, the first transition portion is an arc-shaped segment when the first bottom cover closes the third opening; or, the upper surface of the first transition portion is an arc-shaped surface. Furthermore, at least two first protrusions are arc-shaped protrusions, disposed on the arc-shaped first transition portion.

[0157] Furthermore, in some implementations, when the first bottom cover closes the third opening, a first angle is formed between the first transition portion and the horizontal plane. That is, the first filter box forms a first recessed area (or first concave area) at the first transition portion to accommodate waste, thereby reducing the area occupied by the first sub-base within the first filter box. For example, the first angle may be 15 degrees, 30 degrees, 45 degrees, 60 degrees, 75 degrees, etc. Figure 18 As shown, when the first bottom cover opens the third opening, the setting of the first included angle makes the first transition part tilted as a whole. Therefore, during the process of garbage falling from the third opening into the second filter box, even if some garbage falls onto the first transition part, it will slide down along the tilting direction of the first transition part, preventing garbage residue from remaining on the first transition part. In the above embodiment, when the first transition part is tilted as a whole, there are two possibilities: one is that the first transition part is an inclined section, tilted downwards from its upper end to its lower end relative to the horizontal plane; the other is that the first transition part is an arc-shaped section, curved downwards from its upper end to its lower end relative to the horizontal plane.

[0158] It is worth noting that when the first transition section is an arc-shaped segment, the first angle formed between the first transition section and the horizontal plane refers to the first angle between the tangent line at the concaveest point of the first transition section and the horizontal plane.

[0159] Furthermore, in some embodiments, the first sub-base is closer to the main impeller of the main water pump than the first protrusion, and the upper surface of the first sub-base is located on the path of the first water channel. If the entire upper surface of the first sub-base is flush with the upper surface of the first protrusion, under the drive of the main water pump, after the debris contained in the liquid enters the first filter box, the debris will preferentially remain on the upper surface of the first sub-base. As the debris accumulates on the upper surface of the first sub-base, it is easy to block the first inlet or the first water inlet of the first protrusion. To this end, the first sub-base includes the aforementioned first transition portion 105421b to form a first recessed area. Under the action of the main water pump, the liquid enters the first filter box, and the debris remains in the first recessed area, especially dense debris, such as sand and stones, so that debris will not accumulate on the upper surface of the first sub-base, thus avoiding blockage of the first water inlet or the first water inlet.

[0160] Furthermore, in some embodiments, the first recessed area is closer to the first pivot of the first bottom cover than the second sub-base, and the first recessed area has a higher load-bearing capacity, which can better support heavy objects such as sand and stones within the first recessed area. The connection between the second sub-base and the first frame is more flexible. Furthermore, the first mounting part of the first bottom cover is closer to the main water pump than the first movable part.

[0161] In other embodiments, such as Figure 6 , Figure 12 And refer to Figure 2 As shown, the first sub-base also includes a first mating portion 105421c, which is connected to the first transition portion and fixed to the edge of the first transition portion; when the first bottom cover closes the third opening, the first mating portion abuts against or approaches at least a portion of the bottom of the first frame. In some embodiments, a first recessed area A is formed between the first transition portion, the first mating portion and a portion of the bottom of the first frame (e.g., at least a portion of the lower section).

[0162] In some embodiments, such as Figures 1 to 4 As shown, the first mating portion is closer to the first pivot of the first bottom cover than the first transition portion. For example, when the first bottom cover closes the third opening, the first mating portion is used to close or seal the third opening of the portion, and the first mating portion is connected to the bottom of the first transition portion. When the first bottom cover opens the third opening, the first mating portion is located above the first transition portion. For example, in some embodiments, when the first bottom cover closes the third opening, the first mating portion is a horizontal section, and the connection between the first transition portion and the first mating portion is a smooth transition. The horizontal section of the first mating portion can better press against the third opening to close or seal the third opening of the portion.

[0163] In other embodiments, such as Figure 1As shown, when the first bottom cover closes the third opening, the first mating part is used to close or seal the third opening of the portion. The first mating part is connected to the side and bottom of the first transition portion. For example, in some embodiments, when the first bottom cover closes the third opening, the first mating part provided on the side of the first transition portion is an inclined section or inclined surface, and the first mating part provided at the bottom of the first transition portion is a generally horizontal surface or horizontal section.

[0164] In some embodiments, the first mating portion is further used to connect with the first rotating shaft; or, for mounting the first rotating shaft, in this embodiment, the first mating portion includes a first mounting portion.

[0165] Similar to the first recess, in some embodiments, such as Figure 4 and Figure 5 As shown, at least a portion of the upper part of the first bottom cover is provided with a second recess 1054; when the first bottom cover closes the third opening, a second recessed area B is formed between the second recess and a portion of the bottom of the first frame (e.g., at least a portion of the lower section) for accommodating waste.

[0166] It is worth noting that the first recessed area and the second recessed area refer to the areas where the first bottom cover is recessed downward relative to the upper end of the first protrusion or the liquid inlet channel when the first bottom cover is in the state of closing the third opening.

[0167] In other embodiments, such as Figure 5 and Figure 6 As shown, the first bottom cover includes at least one, two, or more second protrusions 105422c. The second protrusions protrude from the upper surface of the first bottom cover, with adjacent second protrusions spaced apart on the upper part of the first bottom cover and located within a second recess. The arrangement of the second protrusions creates an uneven surface on the upper surface of the first bottom cover, preventing garbage from adhering to the upper surface of the first bottom cover when dumping. For example, the second protrusions can be raised dots, raised strips, raised teeth, or ribs.

[0168] In some embodiments, such as Figure 5 , Figure 6 and Figure 9 As shown, the first bottom cover has a first inlet, and a first recess and a second recess are respectively distributed on both sides of the first inlet. Further, the first recess area and the second recess area are respectively distributed on both sides of the first inlet. Alternatively, in some other embodiments, the first recess and the second recess are arranged around the first inlet.

[0169] In some embodiments, the first recess is closer to the main impeller of the main water pump than the second recess; further, the first recess area is closer to the main impeller of the main water pump than the second recess area.

[0170] In some embodiments, when the first bottom cover is rotatably connected to the first frame, the first recess is closer to the first pivot of the first bottom cover than the second recess; further, the first recess area is closer to the first pivot of the first bottom cover than the second recess area. Alternatively, in some embodiments, the first recess is closer to the first mounting portion than the second recess; further, the first recess area is closer to the first mounting portion than the second recess area.

[0171] In some embodiments, when the first bottom cover is in the state of having the third opening open, the first recess is located above the second recess; further, the first recess area is located above the second recess area.

[0172] In other embodiments, the second sub-base is similar to the first sub-base, such as... Figure 6 , Figure 12 As shown, the second sub-base 105422 includes a second transition portion 105422a, and a second recessed area is formed between the second transition portion and a portion of the bottom of the first frame (e.g., at least a portion of the lower section). Further, at least two second protrusions are provided on the second transition portion; or, at least two second protrusions extend from the second transition portion to the second mating portion. In this embodiment, the second protrusions do not extend into the gap between the bottom of the first frame and the second mating portion when closed, i.e., the second sub-gap, otherwise the first bottom cover cannot close the third opening.

[0173] In some embodiments, when the first bottom cover closes the third opening, the second transition portion is an inclined section; or, the upper surface of the second transition portion is an inclined surface, so that when the first bottom cover opens the third opening, the garbage can slide down along the inclined surface of the second transition portion, avoiding garbage residue on the second transition portion.

[0174] In other embodiments, to further increase the volume of the second recessed area, the second transition portion is an arc-shaped segment when the first bottom cover closes the third opening; or, the upper surface of the second transition portion is an arc-shaped surface. Furthermore, at least two second protrusions are arc-shaped protrusions, provided on the arc-shaped second transition portion.

[0175] Furthermore, in some implementations, when the first bottom cover closes the third opening, a second angle is formed between the second transition portion and the horizontal plane. This reduces the space occupied by the second sub-base within the inner cavity of the first filter box, creating a second recessed area (or second concave area) that can accommodate waste. For example, the second angle can be 15 degrees, 30 degrees, 45 degrees, 60 degrees, 75 degrees, etc. The angle of the second angle can be greater than the first angle, or the angle of the second angle can be equal to or less than the angle of the first angle. The angles of the first and second angles are not limited and can be selected according to actual needs.

[0176] When the first bottom cover closes the third opening, the second included angle causes the second transition portion to be tilted as a whole, reducing the space occupied by the second sub-base within the first filter box. In other embodiments, if the third opening is located above the seventh opening, the second included angle facilitates the first bottom cover to rotate outward through the seventh opening or to rotate towards the third opening through the seventh opening, thereby opening or closing the third opening.

[0177] In the above embodiments, when the second transition portion is in an inclined state, there are two possibilities: one is that the second transition portion is an inclined segment, which is inclined downward relative to the horizontal plane from the upper end to the lower end of the second transition portion; the other is that the second transition portion is an arc-shaped segment, which is curved downward relative to the horizontal plane from the upper end to the lower end of the second transition portion.

[0178] It is worth noting that when the second transition section is an arc-shaped segment, the first included angle between the second transition section and the horizontal plane refers to the first included angle between the tangent line at the concaveest point of the second transition section and the horizontal plane.

[0179] In some embodiments, such as Figure 5 And refer to Figure 2 and Figure 4 As shown, the volume of the first recessed region is greater than the volume of the second recessed region. Alternatively, in some other embodiments, the volume of the first recessed region is not greater than the volume of the second recessed region.

[0180] For example, in another embodiment, the first transition section is closer to the main impeller of the main water pump than the second transition section, and the area of ​​the upper surface of the first filter section is larger than the area of ​​the upper surface of the second transition section, so that the volume of the first recessed area is larger to accommodate more sand, stones and other garbage, and avoid clogging the first inlet or the first water inlet.

[0181] Alternatively, in other embodiments, such as Figure 9 As shown, when the first bottom cover is in the closed third opening state, the bottom of the first recessed area is lower than the bottom of the second recessed area.

[0182] For example, in some embodiments, when the first bottom cover closes the third opening, in the height direction of the first filter box, the first mating part 105421c is lower than the second mating part 105422b, and the first included angle is smaller than the second included angle, thereby forming a larger first recessed area between the first sub-base 105421, the first protrusion, and the first frame, so that some garbage can be deposited in the first recessed area, for example, the garbage is sand, stones, etc.; after the first bottom cover opens the third opening, the garbage in the first recessed area is discharged out of the first filter box through the third opening.

[0183] In other embodiments, similar to the aforementioned first mating portion 105421c, the second sub-base also includes a second mating portion 105422b, which is connected to the second transition portion and fixed to the edge of the second transition portion; when the first bottom cover closes the third opening, the second mating portion abuts against or approaches a portion of the bottom of the first frame (e.g., at least a portion of the lower section). In some embodiments, a second recessed area is formed between the second transition portion, the second mating portion, and the portion of the bottom of the first frame (e.g., at least a portion of the lower section).

[0184] For example, in some embodiments, such as Figure 6 , Figure 12 As shown, the second mating portion is further away from the first pivot of the first bottom cover than the second transition portion. For example, when the first bottom cover closes the third opening, the second mating portion is used to close or seal the third opening of the portion, and the second mating portion is connected to the bottom of the second transition portion. When the first bottom cover opens the third opening, the second mating portion is located below the second transition portion. For example, in some embodiments, when the first bottom cover closes the third opening, the second mating portion is a horizontal segment, and the connection between the second transition portion and the second mating portion is a smooth transition. The horizontal segment of the second mating portion can better press against the third opening to close or seal the third opening of the portion.

[0185] In other embodiments, such as Figure 8 As shown, when the first bottom cover closes the third opening, the second mating part is used to close or seal the third opening of the portion. The second mating part is connected to the side and bottom of the second transition portion. For example, in some embodiments, when the first bottom cover closes the third opening, the second mating part provided on the side of the second transition portion is an inclined section or inclined surface, and the second mating part provided at the bottom of the second transition portion is a generally horizontal surface or horizontal section.

[0186] In other embodiments, similar to the first protrusion described above, such as... Figure 5 and Figure 6 As shown, at least two second protrusions 105422c are provided on the second base. The second protrusions protrude from the upper surface of the second sub-base. Due to the setting of the second protrusions, the upper surface of the second sub-base forms an uneven surface, which prevents garbage from adhering to the upper surface of the second sub-base when dumping garbage.

[0187] In other embodiments, such as Figure 6 , Figure 12As shown, the second base also includes a third sub-base 105423 that connects at least one of the first sub-bases 105421 and 105422. The third sub-base is located between the first and second sub-bases, with one end connected to the first sub-base and the other end connected to the second sub-base; so that the third sub-base, first sub-base, and second sub-base are arranged around the outside of the liquid inlet channel, exposing the liquid inlet channel. For example, there are two third sub-bases to connect the upper portions of the first and second sub-bases and surround the outer periphery of the first protrusion (i.e., forming a clearance opening that exposes the first protrusion). For example, when the first bottom cover closes the third opening, the upper surfaces of the edges of the first, second, and third sub-bases abut or press against the third opening to close it. In some embodiments, the third sub-base is a generally horizontal segment, overlapping or mounted on the upper end of the first base.

[0188] In some embodiments, the first protrusion is disposed on the first base and / or the third sub-base. Further, in some embodiments, the aforementioned first sub-base, second sub-base, and third sub-base are integrally formed on the first protrusion; or, the first sub-base, second sub-base, and third sub-base are integrally formed to form a second base, and then the second base, the first protrusion, and the first base are connected to form a first mounting cavity. For example, the first sub-base, second sub-base, and third sub-base are integrally formed with the first protrusion using an injection molding process to ensure structural strength. Alternatively, in other embodiments, the first sub-base, second sub-base, and third sub-base and the first protrusion may also be configured as a detachable connection for easy maintenance and replacement.

[0189] In some embodiments, to facilitate the installation of the second base onto the first base, the edge of the first base is provided with at least one upwardly protruding first outer edge 105411. The aforementioned first mating portion, second mating portion, and third sub-base are all connected to the first outer edge to form a first mounting cavity. In some embodiments, since the heights of the first mating portion, second mating portion, and third sub-base are different, the first outer edge 105411 includes a first sub-outer edge 105411a, a second sub-outer edge 105411b, and a third sub-outer edge 105411c, wherein the first sub-outer edge is connected to the first mating portion, the second sub-outer edge is connected to the second mating portion, and the third sub-outer edge is connected to the third sub-base.

[0190] In other embodiments, there are two first mounting cavities, each containing at least one counterweight. The two first mounting cavities are distributed on both sides of the first protrusion or the liquid inlet channel. The two first mounting cavities may or may not be connected.

[0191] In another embodiment, the first bottom cover includes the aforementioned first base, second base, and first protrusion; however, no counterweight is provided in the first mounting cavity. The second base facilitates the process where, when the first bottom cover opens the third opening, some of the waste in the first filter box falls onto the second base, allowing it to continue sliding down along the second base and preventing waste residue from remaining on the first bottom cover. Without the second base, during the fall of waste from the first filter box, the first protrusion protrudes from the first base, making it easy for waste to remain on the first protrusion and at the connection point between the first protrusion and the first base, affecting the cleaning effect of the liquid sprayed by the first nozzle on the first filter box.

[0192] In some embodiments, the first filter box further includes a first baffle, which is rotatably disposed on the first bottom cover and is used to open and close the first inlet. For example, the upper end (or inner end) of the first protrusion is provided with a first baffle 10511c, which is used to open or close the upper end of the first protrusion to block the liquid in the pool from entering the first filter box through the first protrusion or to allow the liquid in the pool to enter the first filter box through the first protrusion.

[0193] In some embodiments, such as Figures 8 to 14 As shown, the second mounting part 10511c1 of the first baffle is provided on the first protrusion, and the second movable part 10511c2 of the first baffle can rotate around the second mounting part to open or close the upper end of the first protrusion.

[0194] In some embodiments, such as Figure 6 , Figure 12 As shown, the first bottom cover 1054 includes an overlapping portion 10543 surrounding the outer periphery of the first inlet, and a second mounting portion of the first baffle is rotatably disposed on the overlapping portion. The first baffle abuts against the overlapping portion to close the first inlet; at least a portion of the second movable portion separates from the overlapping portion to open the first inlet. Further, the overlapping portion is disposed around the outer periphery of the first protrusion.

[0195] In some embodiments, the overlapping portion is disposed on the second base, or in other words, the second base includes the overlapping portion; further, in some embodiments, the overlapping portion is disposed on the third sub-base, or in other words, the third sub-base includes the overlapping portion. Alternatively, in other embodiments, the first protrusion includes the overlapping portion, or in other words, the overlapping portion is part of the first protrusion.

[0196] Furthermore, in some embodiments, the overlapping portion includes an overlapping surface, and a first baffle abuts against the overlapping surface. The first baffle closes the first inlet; at least a portion of the second movable portion separates from the overlapping surface, and the first baffle opens the first inlet. For example, in some embodiments, refer to... Figure 7As shown, the overlapping surface includes a first segment 1054241 and a second segment 1054242. When the second mounting part abuts against or is fixed to the first segment, and the second movable part overlaps against or abuts against the second segment, the first bottom cover closes the third opening; when the second movable part separates from the second segment, the first bottom cover opens the third opening. In some embodiments, the width of the first segment is not less than the width of the second segment.

[0197] For example, in some embodiments, the upper part of the second base is higher than the top of the first protrusion, and a step is formed between the upper part of the second base and the top of the first protrusion. The second mounting part of the first baffle is rotatably disposed on the first step surface 105424 of the step. When the first baffle closes the upper end of the first protrusion (i.e., the first inlet or the first water inlet), the second movable part presses tightly against the first step surface of the step to close the upper end of the first protrusion. In this embodiment, the first step surface can serve as an overlapping surface.

[0198] In the above embodiments, the first bottom cover includes the aforementioned first base and second base, with the second base surrounding the overlapping portion; the first base and the second base are connected, and the first protrusion is fixed on the overlapping portion; when the first bottom cover closes the third opening, the upper end of the first protrusion communicates with the inner cavity of the first filter box, and the lower end communicates with the outside; furthermore, at least a portion of the upper part of the second base is higher than the overlapping surface, so that at least a portion of the upper part of the second base forms a step between the upper part of the second base and the abutment portion, and the first step surface of the step can serve as the overlapping surface.

[0199] In some embodiments, refer to Figure 9 As shown, when the first bottom cover closes the third opening, the distance H1 between the second movable part 10511c2 and the upper surface of the first inlet is greater than the distance H2 between the second mounting part 10511c1 and the upper surface of the first inlet. For example, in some embodiments, the first baffle 10511c is inclined downwards from the second mounting part onto the overlapping surface. This arrangement allows the first baffle to be inclinedly overlapped onto the overlapping surface during the opening of the third opening of the first bottom cover. At this time, the first baffle will not open the first opening under its own weight, thus avoiding the situation where garbage gets stuck between the first inlet and the first baffle after the first baffle opens the first opening, causing the first baffle to be unable to seal the first inlet and affecting the cleaning effect. Alternatively, in other embodiments, when the first bottom cover closes the third opening, the first baffle is approximately horizontally overlapped from the second mounting part onto the overlapping surface.

[0200] For example, in some embodiments, such as Figure 19-2 , Figure 20-2As shown, when the first bottom cover is in the closed third opening state, the overlapping surface is an inclined surface that slopes downward from the second mounting portion toward the second movable portion. For example, in one embodiment, in the height direction of the first filter box, the height of the first segment is higher than the height of the second segment. Alternatively, in some embodiments, when the first bottom cover is in the closed third opening state, the overlapping surface is generally planar, and the thickness of the first baffle decreases from the second mounting portion toward the second movable portion. Alternatively, in some embodiments, when the first bottom cover is in the closed third opening state, the overlapping surface is an inclined surface that slopes downward from the second mounting portion toward the second movable portion, and the thickness of the first baffle decreases from the second mounting portion toward the second movable portion.

[0201] For example, in some embodiments, such as Figure 9 As shown, when the first baffle closes the first inlet (or first water inlet) opening, the first step surface of the step slopes downwards from the second mounting part towards the second movable part to form an inclined surface, and the first baffle is in an inclined state; when the first bottom cover opens the third opening, as... Figures 5 to 15 As shown, when trash falls onto the first baffle of the first step surface, since the second movable part of the first baffle is located above the second mounting part and tilts downward from the second movable part to the second mounting part, and the second mounting part is closer to the lower edge of the first protrusion than the second movable part, the trash falling onto the first baffle can slide down along the tilting direction of the first baffle, thus preventing the trash from getting stuck at the first baffle.

[0202] In some embodiments, such as Figure 6 , Figure 12 As shown, the second movable portion of the first baffle is closer to the first pivot of the first bottom cover than the second mounting portion; or, in some embodiments, such as Figure 36 As shown, the second mounting portion of the first baffle is further away from the main water pump of the suction assembly than the second movable portion. Under the action of the main water pump, the second movable portion of the first baffle rotates to open the upper end of the first protrusion, so that the liquid in the pool enters the first filter box through the first protrusion. After being filtered by the first filter box, the liquid passes through the first receiving cavity and the main impeller of the main water pump, and then is discharged from the first outlet of the first body to form the first water path. When the first baffle is open, the first baffle is not in the path of the first water path, and the obstruction force on the water flow is small, so that the liquid flows more smoothly in the first water path.

[0203] Alternatively, in some embodiments, the second movable portion of the first baffle is further away from the first pivot of the first bottom cover than the second mounting portion; or, in some embodiments, the second mounting portion of the first baffle is closer to the main water pump of the suction assembly than the second movable portion.

[0204] In some embodiments, such as Figure 8 , Figure 13 and Figure 14 As shown, the first baffle 10511c includes a first thinning portion 10511c3, which is closer to the second mounting portion than the second movable portion; the thickness of the first thinning portion is less than the thickness of the second mounting portion. The first thinning portion is provided to increase the rotational freedom at the point where the first baffle and the second mounting portion are adjacent, making it easier for the second movable portion to rotate relative to the second mounting portion.

[0205] In some embodiments, the first baffle forms a first thinning portion by providing a recess; or, the first baffle forms a first thinning portion by providing a stepped structure and utilizing the thickness difference of the steps; or, the first baffle forms a first thinning portion by providing a hollow structure.

[0206] In some embodiments, such as Figure 13 As shown, in the width direction of the first baffle, the first distance L1 between the first thinned portion and the second mounting portion is less than half the width of the first baffle; or, in the width direction of the first baffle, the first distance L1 is less than the second distance L2 between the first thinned portion and the middle portion of the first baffle.

[0207] In some embodiments, such as Figure 14 As shown, the first baffle also includes at least two fourth protrusions 10511c4, with adjacent fourth protrusions spaced apart on the top of the first baffle. The presence of these fourth protrusions creates an uneven surface on the upper surface of the first baffle, preventing garbage from adhering to the upper surface of the first baffle when it is dumped. For example, the fourth protrusion can be a dot, a strip, a tooth, or a rib.

[0208] Furthermore, in some embodiments, such as Figure 14 As shown, the first baffle also includes at least one third protrusion 10511c5, which is located between two adjacent fourth protrusions, and the top of the third protrusion is not flush with the top of the fourth protrusion, so as to further prevent garbage from adhering to the upper surface of the first baffle through the uneven surface between the third and fourth protrusions.

[0209] In the above embodiments, the top of the third protrusion is not flush with the top of the fourth protrusion, including but not limited to the top of the third protrusion being higher or lower than the top of the fourth protrusion.

[0210] In some embodiments, the third protrusion and / or the fourth protrusion are disposed away from the second movable portion, the second mounting portion, and the thinning portion; further, the thinning portion is located between the second mounting portion and the third protrusion and / or the fourth protrusion.

[0211] In some embodiments, the first baffle is a flexible component, for example, the first baffle is made of any one or more composite materials selected from rubber, silicone, TPE, TPR, TPU, soft PVC, EVA, flexible PP, and flexible nylon.

[0212] In some embodiments, refer to Figure 17 As shown, at least one of the overlapping portion and the second mounting portion has at least one mounting hole 10511c7, and at least the other has at least one fixing head 10511c6. The fixing head is inserted into the mounting hole, so that the second mounting portion is rotatably disposed on the overlapping portion. Furthermore, the fixing head is a flexible component, for example, the fixing head is made of any one or more composite materials selected from rubber, silicone, TPE, TPR, TPU, soft PVC, EVA, flexible PP, and flexible nylon, and the fixing head can be a mushroom-shaped structure.

[0213] In some embodiments, such as Figures 7 to 9 As shown, the first bottom cover also includes at least one support member 10544 disposed within the first inlet. When the first bottom cover closes the third opening, the support member assists the second section in supporting the second movable part, so that a portion of the second movable part abuts against the top of the support member.

[0214] Furthermore, in some embodiments, such as Figures 7 to 9 As shown, the support member is disposed within the liquid inlet channel. For example, in some embodiments, one side of the liquid inlet channel includes a generally vertical section 1054f and an inclined section 1054g, the inclined section being connected to the vertical section and located above the vertical section, and the support member being disposed on the inclined section; furthermore, the side of the support member facing the liquid inlet channel is approximately flush with the side of the vertical section facing the liquid inlet channel, thereby ensuring that the support member does not occupy the internal space of the liquid inlet channel.

[0215] In some embodiments, such as Figure 2 , Figure 4 , Figure 16 As shown in Figures 19 and 20, the first filter box further includes at least one first guide portion 10512. When the first bottom cover is in the open third opening state, the first guide portion is used to guide the debris falling on it toward the third opening. For example, in some embodiments, the first guide portion is located on the inner side of the side portion of the first frame and protrudes from the aforementioned inner side; for example, as... Figure 2 , Figure 16 As shown in Figures 19 and 20, the first guide portion protrudes from the inner side of the first side portion of the first frame; or, further, the first guide portion protrudes from the inner side of the lower section; for example, the first guide portion protrudes from the inner side of the first side wall and / or the second side wall.

[0216] In some embodiments, such as Figure 2 , Figure 16As shown in Figures 19 and 20, the first guide portion includes a guide segment 105121 for guiding waste in the first filter box to the third opening. In some embodiments, the guide segment is an inclined segment, or in other words, the upper surface of the guide segment is an inclined surface. For example, the guide segment slopes downwards from its upper part to its lower part. Further, the guide segment slopes towards the center of the third opening or the second side of the first frame from its upper part to its lower part, that is, the upper part of the guide segment is farther away from the center of the third opening or the second side of the first frame than its lower part. Alternatively, in other embodiments, the guide segment is a generally vertical segment, or in other words, the upper surface of the guide segment is a generally planar surface. Alternatively, in other embodiments, the guide segment is an arcuate segment, or in other words, the upper surface of the guide segment is an arcuate surface.

[0217] Furthermore, in some embodiments, such as Figure 2 , Figure 16 As shown in Figure 20, the first guide section also includes an extension section 105122 for guiding the waste in the first filter box from the guide section to the third opening. The extension section is connected to the guide section; specifically, the upper part of the extension section is connected to the lower part of the guide section, and the lower part of the extension section is closer to the third opening than its upper part.

[0218] In some embodiments, as shown in FIG20, the extension segment is an inclined segment, or in other words, the upper surface of the extension segment is an inclined surface. Alternatively, in other embodiments, the extension segment is a generally vertical segment, or in other words, the upper surface of the extension segment is a generally planar surface. Alternatively, in other embodiments, the extension segment is an arcuate segment, or in other words, the upper surface of the extension segment is an arcuate surface.

[0219] In some embodiments, the tilt angle of the extension segment is smaller than that of the guide segment. For example, in one embodiment, the guide segment and the extension segment are sequentially connected to form a raised segment. Further, the guide segment tilts from top to bottom toward the center of the third opening or the second side of the first frame, and the extension segment tilts from top to bottom toward the second side of the first frame away from the center of the third opening; that is, the upper part of the extension segment is closer to the center of the third opening and the second side of the first frame than the upper part of the guide segment.

[0220] In the above embodiments, the first bottom cover abuts against the third opening in at least two ways: one is that the first bottom cover and the third opening are in direct contact, i.e., they are in tight contact without any gap; the other is that there is a first gap between the first bottom cover and the third opening. The main purpose of this design is that, during actual manufacturing and assembly, when the first bottom cover closes the third opening, a first gap will naturally exist between the first bottom cover and the third opening. Simultaneously, the existence of this first gap can prevent the first bottom cover from rigidly impacting the first frame during opening and closing, thereby reducing structural wear and noise and extending service life. In some embodiments, the first gap is no greater than 1 cm.

[0221] Therefore, in some embodiments, such as Figure 15 As shown, a first gap 105a1 is formed between the upper part of the first bottom cover and the bottom of the first frame. The existence of this first gap causes some fine sand, algae, and other debris to leak out when the third opening is closed by the first bottom cover. Therefore, in some embodiments, such as... Figure 15 , Figure 16 As shown, the first filter box further includes at least one first shielding member, which is disposed on at least one of the first bottom cover and the first frame. When the first bottom cover is in the closed third opening state, the first shielding member is used to shield at least a portion of the first gap to prevent garbage from leaking out of the first filter box from at least a portion of the first gap.

[0222] Furthermore, in some embodiments, such as Figure 15 , Figure 16 As shown, at least one first shielding member 1058 is located inside the first gap; or, in other embodiments, at least one first shielding member is located inside the first gap or outside the first gap.

[0223] In order to mount the first shielding member onto the first filter box, in some embodiments, such as Figures 21 to 24 As shown, the first filter box further includes a mounting hole 10581 and a fixing protrusion 10582. The mounting hole is provided on one of the first bottom cover and the first frame, and the fixing protrusion is provided on the first shielding member; or, the mounting hole is provided on the first shielding member, and the fixing protrusion is provided on one of the first bottom cover and the first frame; at least a portion of the fixing protrusion is provided in the mounting hole to install the first shielding member on the first bottom cover or the first frame.

[0224] To facilitate the assembly and disassembly of the fixed protrusion, furthermore, in some embodiments, such as Figure 21 and Figure 22 As shown, the mounting hole 10581 communicates with the outside through at least one first notch 105811; the fixing protrusion is installed in the mounting hole through the first notch and removed from the mounting hole.

[0225] Furthermore, in some embodiments, such as Figure 24 As shown, the first shielding member includes a third mounting portion 10583 and a third movable portion 10584, with the third mounting portion disposed on the first frame or the first bottom cover. Further, the first shielding member includes a second thinning portion 10585, which is closer to the third mounting portion than the third movable portion, and its thickness is less than that of the third mounting portion. The second thinning portion is provided to increase the rotational freedom at the point adjacent to the third mounting portion, making it easier for the third movable portion to rotate relative to the third mounting portion, thus facilitating the assembly and disassembly of the first shielding member.

[0226] In some embodiments, the first shielding member forms the second thinning portion by providing a recess; or, the first shielding member forms the second thinning portion by providing a stepped structure and utilizing the difference in step thickness; or, the first shielding member forms the second thinning portion by providing a hollow structure.

[0227] In some embodiments, the first shielding member is a flexible member, for example, the first shielding member is made of any one or more composite materials selected from rubber, silicone, TPE, TPR, TPU, soft PVC, EVA, flexible PP, and flexible nylon.

[0228] In some embodiments, such as Figure 2 and Figure 4 As shown, the first gap 105a1 includes at least a first sub-gap 105a1 and a second sub-gap 105a2. For example, the first mounting portion of the first bottom cover is rotatably disposed on the first side portion. When the first bottom cover is in the state of closing the third opening, a first sub-gap is formed between the first side portion and the first mounting portion; a second sub-gap is formed between the second side portion and the second movable portion.

[0229] Furthermore, in some embodiments, at least one first shielding member is provided on the second side or the second movable part. When the first bottom cover is in the state of closing the third opening, the first shielding member is used to shield the second sub-gap to prevent garbage from leaking out of the first filter box from the second sub-gap.

[0230] In other embodiments, such as Figure 2 and Figure 4 As shown, the first gap also includes a third sub-gap 105a3 and a fourth sub-gap 105a4. For example, when the first bottom cover is in the state of closing the third opening, the second and third sub-gap portions of the first bottom cover are respectively formed between the third side portion 105313 and the fourth side portion 105314.

[0231] Furthermore, in some embodiments, at least one first blocking member is also provided on the third side or the side of the first bottom cover. When the first bottom cover is in the state of closing the third opening, the first blocking member is used to block the third sub-gap to prevent garbage from leaking out of the first filter box from the third sub-gap. Additionally, at least one first blocking member is also provided on the fourth side or the other side of the first bottom cover. When the first bottom cover is in the state of closing the third opening, the fourth blocking member is used to block the fourth sub-gap to prevent garbage from leaking out of the first filter box from the fourth sub-gap.

[0232] In some embodiments, such as Figure 3As shown, the first bottom cover is rotatably connected to the first frame via a first pivot. For example, the first mating part of the first bottom cover is rotatably disposed on the first side of the first frame (e.g., the first sidewall 1053b1). Furthermore, the first mating part of the first bottom cover is rotatably connected to the first side of the first frame (e.g., the first sidewall 1053b1) via a first pivot. When the first bottom cover closes the third opening, the first bottom cover and the first frame are in abutting connection; for example, the first mating part and / or the first transition part are in abutting connection with the first side of the first frame (e.g., the first sidewall). Since it is necessary to ensure a tight abutting connection between the first bottom cover and the first frame when the third opening is closed, therefore, as... Figure 2 As shown, when the first bottom cover opens the third opening, there will be a first sub-gap at the rotatable connection between the first bottom cover and the first frame. For example, there will be a first sub-gap between the first mating part and the first side part (e.g., the first side wall).

[0233] To prevent debris from falling into the first sub-gap and affecting the normal opening and closing of the first bottom cover, debris discharged from the first side of the first frame should be guided as much as possible onto the first bottom cover. This allows the debris to flow away from the first mating part or the first side, preventing it from entering the first sub-gap. For example, debris discharged from the first side of the first frame should be guided as much as possible onto the first sub-base, allowing it to flow away from the first mating part or the first side, preventing it from entering the gap.

[0234] Therefore, in some embodiments, such as Figure 2 As shown, at least one first guide portion is provided on the inner side of the first side portion, and the lower part of the first guide portion is located inside the first sub-gap to guide the garbage as far as possible onto the first bottom cover. That is, the lower part of the first guide portion and the first sub-gap are offset in the height direction, and in the horizontal direction, the lower part of the first guide portion is located inside the first sub-gap. This allows the garbage to fall into the third opening after sliding down from the first guide portion, instead of falling into the first sub-gap, thus preventing the garbage from getting stuck in the first sub-gap.

[0235] In the above embodiments, such as Figure 19-1 and Figure 19-2 As shown, when the first guide portion includes a guide portion, the lower part of the guide portion is located inside the first sub-gap; as Figure 20-1 and Figure 20-2 As shown, when the first guide portion also includes an extension portion, the lower part of the extension portion is located inside the first sub-gap.

[0236] It is worth noting that the lower part of the first guide is located inside the first sub-gap, meaning that in the horizontal direction, the lower part of the first guide is closer to the center of the third opening or the second side of the first frame than the first sub-gap. This allows debris sliding off the first guide to fall into the third opening instead of the first sub-gap, preventing it from getting stuck. For example, debris sliding off the first guide will first be guided to the first sub-base of the first bottom cover and move along the first sub-base away from the first mating part, the first side, or the first sidewall, instead of falling directly into the first sub-gap.

[0237] Furthermore, in other embodiments, such as Figure 6 , Figure 12 As shown, the first bottom cover also includes at least one second guide portion (or a first transition portion 105421b). When the first bottom cover is in the state of having the third opening open, at least a portion of the second guide portion is located directly below the third opening, so that some of the trash falling from the third opening can slide off the first bottom cover under the guidance of the second guide portion. In some embodiments, the second guide portion is the aforementioned first transition portion, and its structure is the same as that of the first transition portion.

[0238] It is worth noting that the garbage falling from the third opening includes garbage that falls directly from inside the first filter box to the third opening, as well as garbage that is guided to the third opening from the first guide section.

[0239] In some embodiments, the second guide portion is disposed on the upper part of the first bottom cover, for example, in one embodiment, such as... Figure 13 As shown, the second guide portion is disposed on the first sub-base. In some embodiments, the second guide portion is the aforementioned first transition portion, and its structure is the same as that of the first transition portion.

[0240] In order to smoothly guide the debris falling on the first bottom cover so that it slides off the first bottom cover, in some embodiments, such as Figure 15 , Figures 17 to 18 As shown, the second guide portion includes a first recess in the first bottom cover. The first recess includes a first end portion 1054e2 and a second end portion 1054e3, with the first end portion being closer to the pivot of the first bottom cover than the second end portion. When the first bottom cover is in the open third opening state, the first recess slopes downward from its first end portion toward its second end portion to form a first guide surface, allowing debris to slide off the first bottom cover along the first guide surface.

[0241] Similar to the first transition section described above, in some embodiments, such as Figures 17 to 18 As shown, the first guide surface is an inclined surface; or, as... Figure 15 As shown, in some other embodiments, the first guide surface is an arc-shaped surface.

[0242] Similar to the first transition section described above, in some embodiments, such as Figure 15 And refer to Figure 2 As shown, the second guide portion also includes at least two first protrusions, with two adjacent first protrusions spaced apart within the first recess.

[0243] In some embodiments, such as Figure 15 As shown in Figures 19 and 20, when the first bottom cover is in the state of having the third opening open, the second guide portion is located above the first protrusion portion, so that some of the garbage on the second guide portion can be removed from the first bottom cover via the first baffle and / or the first protrusion portion.

[0244] Similar to the second guide portion, in some embodiments, the first bottom cover also includes a first clearance portion (or a second transition portion 105422a), with the first clearance portion and the second guide portion distributed on both sides of the first protrusion. When the first bottom cover is in the state of having the third opening open, the first clearance portion is located below the first protrusion. In some embodiments, the first clearance portion is the aforementioned second transition portion, and its structure is the same as the second transition portion.

[0245] In some embodiments, the pool robot further includes a sixth position detection component 1081 (or an opening detection device) for the first filter box, used to detect whether the first bottom cover closes the third opening (or the first drain outlet), that is, to detect whether the first bottom cover opens the third opening. The sixth position detection component includes at least one detection element and at least one mating element. As a preferred example of this application, the detection element is at least one of a Hall sensor 1081a, a photoelectric sensor, a pressure sensor, a capacitive sensor, an inductive sensor, or a micro switch. The position signal of the first bottom cover is generated by the cooperation of the detection element and the mating element to determine whether the first bottom cover closes the third opening.

[0246] For example, such as Figure 33 , Figure 34 and Figure 40 The sixth positioning detection component includes a Hall sensor 1081a and a magnetic element 1081b (e.g., an iron block). One of the magnetic element and the Hall sensor is located on the first bottom cover, and the other is located on the first main body, for example, on or near the first filter box. When the Hall sensor detects the magnetic element, it indicates that the first bottom cover is closed to the third opening; otherwise, it indicates that the first bottom cover is open to the third opening. Alternatively, one of the magnetic element and the Hall sensor is located on the first bottom cover, and the other is located on the base station, for example, on or near the second filter box. When the Hall sensor detects the magnetic element, it indicates that the first bottom cover is open to the third opening; when the Hall sensor does not detect the magnetic element, it indicates that the first bottom cover is closed to the third opening.

[0247] For example, in one embodiment, such as Figure 33 As shown, a Hall sensor is mounted on the first filter box; an iron block 1081b is mounted on the first bottom cover. When the Hall sensor detects the iron block, it indicates that the first bottom cover has closed the third opening; otherwise, it indicates that the first bottom cover has opened the third opening. In this embodiment, the seventh positioning detection component and the sixth positioning detection component can be the same component. That is, when the Hall sensor senses the magnet mounted on the first bottom cover, it is considered that the first bottom cover has closed the third opening, and the first filter box has been installed in place. Alternatively, in another embodiment, as... Figure 34 As shown, a Hall sensor is mounted on the base station, and an iron block is mounted on the first bottom cover. When the Hall sensor detects the iron block, it indicates that the first bottom cover is open at the third opening; otherwise, it indicates that the first bottom cover is closed at the third opening. Alternatively, in another embodiment, two Hall sensors are provided, one on the first main body and the other on the base station, with the iron block mounted on the first bottom cover. When the Hall sensor on the base station detects a magnetic element, but the Hall sensor on the first main body does not, it indicates that the first bottom cover is open at the third opening; conversely, when the Hall sensor on the base station does not detect a magnetic element, but the Hall sensor on the first main body does, it indicates that the first bottom cover is closed at the third opening. In this embodiment, the use of two Hall sensors ensures that the first bottom cover is open and at least a portion of it extends into the fourth opening or at least a portion extends into the second filter box, thus guaranteeing the accuracy of the detection.

[0248] In some embodiments, the pool robot further includes a seventh positioning detection component for the first filter box, used to detect whether the first filter box is properly installed within the first body, i.e., to detect whether the first filter box is correctly installed within the first body. The seventh positioning detection component includes at least one detection element and at least one mating element. As a preferred example of this application, the detection element is at least one of a Hall sensor, photoelectric sensor, pressure sensor, capacitive sensor, inductive sensor, or microswitch. The detection element and the mating element work together to generate a position signal for the first filter box, thereby determining whether the first filter box is properly installed. The sixth and seventh positioning detection components can be the same component or different components.

[0249] For example, the seventh positioning detection component includes a Hall sensor and a magnetic element (e.g., an iron block), wherein one of the magnetic element and the Hall sensor is disposed on the first filter cartridge, and the other is disposed on the first body. When the Hall sensor detects the magnetic element, it indicates that the first filter cartridge has been installed in place within the first body; otherwise, it indicates that the first filter cartridge has not been installed in place within the first body. For example, in some embodiments, such as... Figure 33 and Figure 34As shown, the iron block is disposed on the side or bottom of the first filter box, and the Hall sensor is mounted on the first body. Alternatively, in some embodiments, the iron block is disposed on the first bottom cover, and the Hall sensor is mounted on the first body. In this embodiment, the seventh position detection component and the sixth position detection component can be the same component.

[0250] When the pool robot adopts a double-layer first filter box structure, it includes an outer first filter box (corresponding to the first filter box) and an inner first filter box. The inner first filter box is for fine filtration, and the outer first filter box is for coarse filtration. In this case, the pool robot also has a positioning detection component for the inner first filter box to detect whether the inner first filter box is properly installed in the first main body. The type of positioning detection component for the inner first filter box can be the same as that of the seventh positioning detection component, and will not be described further here. The positioning detection component for the inner first filter box can be the same type as the sixth and / or seventh positioning detection components or different types.

[0251] For example, in one embodiment, an iron block is installed at the bottom of the inner first filter box, and a Hall sensor is installed on the first body. In this embodiment, the positioning detection component of the inner first filter box can be the same component as the sixth positioning detection component and / or the seventh positioning detection component. That is, when the Hall sensor senses the magnet provided on the bottom of the inner first filter box, it is considered that the inner first filter box has been installed in place, and the first filter box is considered to be installed in place.

[0252] 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 through the third opening. For example, when the pool robot is parked on the base station, and the first nozzle needs to discharge the waste in the first filter box into the second filter box of the base station during the cleaning process, the first bottom cover needs to open the third opening; or, when cleaning the first filter box in other ways, the first bottom cover needs 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.

[0253] 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. 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 to prevent waste from the first filter box from being 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 from the first body, to ensure that the first bottom cover remains closed during or after the user removes the first filter box, and before the user manually opens the first bottom cover, the third opening is kept closed to prevent waste from the first filter box from falling out through the third opening.

[0254] Therefore, in some embodiments, the first bottom cover has a locked state and an unlocked state. When the first bottom cover is in the locked state, it is locked to the first frame, keeping the third opening closed. When the first bottom cover is in the unlocked state, it can move relative to the first frame to open or close the third opening. For example, the first bottom cover is in the locked state when the pool robot is inside the pool cleaning the pool liquid or when the pool robot is outside the pool not cleaning the first filter box; the first bottom cover is in the unlocked state when the pool robot is on or off the base station body cleaning the first filter box.

[0255] In some embodiments, such as Figure 1 As shown, the pool robot also includes a locking mechanism 1080, which is used to lock the first bottom cover to the first frame or the side wall of the first filter box 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.

[0256] Correspondingly, in some embodiments, such as Figure 25 As shown, the pool robot or base station body is equipped with an unlocking mechanism 7003, which is used to unlock the locking mechanism 1080 from locking the first bottom cover. Alternatively, in some other embodiments, in the second state, the locking mechanism is manually operated by the user to unlock the first bottom cover.

[0257] 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 by magnetic attraction. Alternatively, in other embodiments, the locking mechanism locks the first bottom cover to the first frame by a snap-fit ​​structure. Or, in still other embodiments, the locking mechanism locks the first bottom cover to the first frame by the self-locking force of a motor.

[0258] For example, in some embodiments, the locking mechanism locks the first bottom cover onto the first frame by extending or rotating; correspondingly, the unlocking mechanism drives the locking mechanism to retract or rotate 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.

[0259] In some embodiments, such as Figures 29 to 32 As shown, the locking mechanism includes at least one first limiting part and at least one locking member 10802. The locking member is slidably disposed relative to the first limiting part, with one of the locking member and the first limiting part located on the first bottom cover and the other on the first frame. In the locked state, the locking part of the locking member extends into the first limiting part, locking the first bottom cover onto the first frame; in the unlocked state, the locking part of the locking member retracts from the first limiting part, separating from it, thus releasing the locking of the first bottom cover onto the first frame. Correspondingly, the unlocking mechanism is used to drive the locking member to retract, thereby disengaging it from the first limiting hole.

[0260] For example, in some embodiments, the locking member switches between entering and exiting the limiting hole by telescopic movement. Alternatively, in other embodiments, the locking member switches between entering and exiting the limiting hole by rotation.

[0261] Furthermore, such as Figures 29 to 32 As shown, the locking mechanism further includes at least one fourth elastic member 10803, which is connected to the locking member. The fourth elastic member applies a first biasing force, a first preload, or a first elastic force to the locking member, forcing the locking portion of the locking member to tend to remain within the first limiting portion.

[0262] For example, such as Figures 29 to 32 As shown, the first limiting part includes at least a first limiting hole 10801, one of the 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 locking member, forcing the 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 locking member to retract and move to exit the first limiting hole.

[0263] For example, such as Figures 29 to 32As shown, the first limiting hole 10801 is provided on the first frame, and the locking member is telescopically or slidably provided on the first bottom cover. The locking member has a locking part 108021 and a first mounting end 108022. The fourth elastic member is a compression spring. One end of the fourth elastic member is provided on the first mounting end of the locking member, and the other end is provided on the first bottom cover. The compression spring applies a first elastic force to the locking member in the direction of the first limiting hole, so that the locking part of the locking member tends 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.

[0264] In some embodiments, such as Figure 29 As shown, one of the first bottom cover and the first frame has a second mounting cavity 1054i, and the other has a first limiting hole, which is located outside the second mounting cavity. A locking member is slidably disposed within the second mounting cavity. A fourth elastic member is disposed within the second mounting cavity and connected to the locking member. Under the action of a first preload, at least a portion of the locking part is located outside the second mounting cavity. In some embodiments, the second mounting cavity may be at least a part of the first mounting cavity; for example, the second mounting cavity may serve as the first mounting cavity.

[0265] For example, the first bottom cover includes a second mounting cavity, the first mounting end of the locking member is disposed in the second mounting cavity, the fourth elastic member is disposed in the second mounting cavity and connected to the locking member, the first bottom cover is provided with a first sliding hole 10804, the first sliding member communicates with the outside, and the locking part of the locking member is located outside the first bottom cover through the first sliding hole; or, the locking member is slidably disposed on the first sliding hole, the first mounting end of the locking member is located in the second mounting cavity, and the locking part of the first telescopic member is located outside the first bottom cover.

[0266] In some embodiments, when the locking member is installed in the first sliding hole, the locking member can be inserted into the first sliding hole from one end for installation; or, in another embodiment, the first sliding hole includes a second notch for the locking member to be installed in the first sliding hole through the second notch. In this embodiment, the locking member can be moved from the upper part of the first bottom cover to the lower part of the first bottom cover (i.e., from top to bottom) to be inserted into the first sliding hole.

[0267] In some embodiments, such as Figure 32 As shown, the first filter box also includes at least one second shield 1059 for preventing external debris from entering the first bottom cover through the first sliding hole. The second shield is disposed between the first sliding hole and the second mounting cavity, and at least blocks at least a portion of the first sliding hole.

[0268] In some embodiments, the second shielding member is a flexible member, for example, the second shielding member is made of any one or more composite materials selected from rubber, silicone, TPE, TPR, TPU, soft PVC, EVA, flexible PP, and flexible nylon.

[0269] Furthermore, in some embodiments, the second shielding member is provided with a second clearance opening 10591, which is connected to the first sliding hole; the locking part of the locking member 10802 extends out of the first bottom cover through the second clearance opening and the first sliding hole.

[0270] Furthermore, referring to Figure 32 As shown, in some embodiments, the second shielding member is further provided with a support portion 10592 located below the second clearance opening and a movable groove 10593 located above the second clearance opening. Correspondingly, an insert portion 10547 and a fifth protrusion 10546 are provided at corresponding positions on the first bottom cover. The support portion is housed within the insert portion, and the fifth protrusion is inserted into the movable groove. That is, the fifth protrusion cooperates with the movable groove and assists in the fitting relationship between the support portion and the insert portion, thereby ensuring that the second shielding member can be stably mounted on the first bottom cover and improving the structural stability of the second shielding member.

[0271] In some embodiments, such as Figure 5 , Figures 9 to 10 As shown, the first bottom cover 1054 is also provided with at least one receiving groove 10545, and when the first bottom cover closes the third opening, at least a portion of the locking member 10802 is located in the receiving groove. Further, in some embodiments, when the first bottom cover closes the third opening, at least a portion of the first extension 10536 is located in the receiving groove.

[0272] In some embodiments, the unlocking mechanism drives the locking member to retract, thereby disengaging it from the first limiting hole. For example, the unlocking mechanism includes at least one driving component and at least one unlocking component. The driving component includes at least a first motor, which drives the unlocking component to extend or rotate, thereby pushing the locking member to retract and disengage it from the first limiting hole. The driving component may also be a cylinder or other driving source. The unlocking component may be at least one unlocking rod or other non-rod-shaped structure.

[0273] In other embodiments, the user can press the locking member into the second mounting cavity to drive the locking member to retract and exit the limiting hole, thereby manually releasing the locking member from the first bottom cover. The first bottom cover can then move relative to the first frame to open the third opening.

[0274] When the locking member on the first bottom cover is unlocked by the unlocking mechanism or manually released, allowing the third opening to be opened, the first bottom cover can be manually driven or driven by other forces to move toward the third opening, thereby closing the third opening. At this time, under the action of the elastic member, the locking member extends into the limiting hole, completing the locking of the first bottom cover.

[0275] In other embodiments, the locking member is rotatably disposed on one of the first bottom cover and the first frame, and the 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 spring, the locking end of the locking member tends to be kept 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; or it can also be a tension spring. Correspondingly, the unlocking member can push the locking member to rotate through the aforementioned telescopic movement or rotation, causing the locking end of the locking member to exit the first limiting hole, thereby unlocking the locking member.

[0276] In some embodiments, when a locking mechanism 1080 is provided on the first bottom cover, the locking mechanism includes the aforementioned locking member, the fourth elastic member, and the first limiting hole. For example, as... Figures 26 to 30 As shown, the first frame is provided with a downwardly extending first extension 10536, and a first limiting hole is provided on the first extension. When the first bottom cover needs to close the third opening, the closing mechanism provided in the base station or the first main body drives or manually drives the first bottom cover to rotate toward the third opening. When the locking member reaches the first extension and is located below the first limiting hole, the first extension squeezes the locking member to retract, so that the first bottom cover can continue to rotate toward the third opening. When the locking member rotates to the first limiting hole, the first extension removes the squeezing action on the locking member. Under the action of the fourth elastic member, the locking member extends to insert into the first limiting hole, thereby realizing the locking of the first bottom cover.

[0277] In some embodiments, such as Figure 29 As shown, the end of the inner side of the first extension 10536 (i.e. the side closer to the first bottom cover) is set as a slope. The slope is set so that when the first bottom cover rotates to close the third opening, the slope contacts the first bottom cover first, so as to guide the first bottom cover to smoothly close the third opening and reduce the jamming when the first bottom cover moves to close the third opening.

[0278] like Figures 35 to 41 As shown, an exemplary embodiment of this disclosure also provides a cleaning system. The cleaning system includes a pool robot 1000 and a base station 2000, wherein the base station is at least used to clean the pool robot's first filter cartridge 1051, so that debris in the first filter cartridge is transferred from the pool robot or temporarily stored in the base station. Further, as... Figures 40 to 42 As shown, in some embodiments, the base station includes at least a base station body 20001 and a second filter box 21102, at least a portion of which is located within the base station body. The second filter box is used to receive and further filter debris from the first filter box.

[0279] Base station 2000 is the support center of the cleaning system, providing services such as docking, cleaning, and charging for the pool robot. The base station body 20001 constitutes the main support structure of the base station, and its top is equipped with a resting surface 200018 for the pool robot to dock.

[0280] In some embodiments, the base station further includes a second cleaning component, which includes at least one first nozzle 2173. The first nozzle can clean the first filter box by spraying liquid onto it. When the pool robot stops on the resting surface of the base station body, the liquid is sprayed through the first nozzle to clean the first filter box, causing debris in the first filter box to fall into the second filter box, thereby transferring the debris from the first filter box to the second filter box.

[0281] In some embodiments, at least a portion of the third opening is located on the bottom of the first filter box. When the pool robot stops on the base station body and the first bottom cover opens the third opening, the third opening can communicate with the third inlet of the second filter box, so that the garbage and liquid in the first filter box can be discharged from the third opening and fall into the second filter box through the third inlet.

[0282] In some embodiments, such as Figure 42 As shown, the second filter box 21102 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 21101, which serves as the entry point for waste into the second filter box.

[0283] For the second filter cartridge, in some embodiments, such as Figure 42 As shown, the second filter box includes a second frame 2112 and a second filter screen 2113. The second filter screen is disposed on the second frame to form a filter surface.

[0284] In some embodiments, such as Figure 42 As shown, the second filter box also includes at least one positioning hole 2114, which cooperates with at least one positioning post (not shown) in the base station to stably install the second filter box in the base station.

[0285] To prevent excessive liquid residue in the second filter box from causing the collected waste inside to smell, in some embodiments, such as Figure 42 As shown, the second filter box also includes at least one second water outlet 2115 for timely discharge of at least a portion of the liquid inside the second filter box. Furthermore, the second water outlet is positioned at a location at least above the bottom of the filter surface of the second filter box; for example, the second water outlet is closer to the top of the filter box or the third inlet than the filter surface of the second filter box.

[0286] Alternatively, in some embodiments, the second filter box is the 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 located outside or inside the second frame.

[0287] Alternatively, in some embodiments, such as Figures 42 to 43 As shown, a second filter bag 2116 is also provided inside the second filter box. The second filter bag has a fifth inlet 21161, which can communicate with the third opening. The second filter bag is used at least to collect garbage falling from the first filter box; the second filter box is used at least to perform secondary filtration on the liquid filtered by the second filter bag. Through the dual-layer filtration of the second filter bag and the second filter box, the filtration effect of garbage is further improved. Furthermore, the second filter bag is detachably installed inside the second filter box for easy periodic replacement.

[0288] The first filter bag and the second filter bag can have the same structure or different structures. The following explanation will only use the structure of the second filter bag as an example.

[0289] In some embodiments, the second filter bag is made of a deformable material; such as Figure 43 As shown, the second filter bag also includes a closing mechanism 2117, which is movably disposed at the fifth inlet 21161 of the second filter bag. The closing mechanism is used to close or open the fifth inlet. When the second filter bag is full or has collected a preset amount of garbage, because the second filter bag is made of a deformable material, the user can operate the closing mechanism to close or shut the fifth inlet, sealing the garbage inside the second filter bag to form a sealed garbage bag. This makes it easy for the user to remove the second filter bag from the second filter box, preventing the garbage inside the second filter bag from falling onto the base station or the ground and causing secondary pollution. When the user needs to empty or clean the garbage from the second filter bag, the user operates the closing mechanism to open the fifth inlet, allowing the garbage inside the second filter bag to be cleaned out through the fifth inlet, and the second filter bag can be reused. Alternatively, the user does not need to clean the garbage inside the second filter bag through the fifth inlet; the user can directly discard the second filter bag and replace it with a new one.

[0290] In some embodiments, the second filter bag can be a disposable filter bag or a reusable filter bag. The filter bag material can be non-woven fabric, filter cotton, nylon mesh, biodegradable materials, or composite filter membranes, etc.

[0291] In some embodiments, such as Figures 44 to 46As shown, the drawstring mechanism 2117 includes at least a drawstring 21171. An annular channel is provided at the fifth inlet of the second filter bag, and the drawstring is disposed inside the annular channel with both ends outside the annular channel to facilitate user operation of the drawstring ends to close or open the fifth inlet. Furthermore, in some embodiments, the drawstring may be configured as an elastic pull cord.

[0292] For example, the starting end of the annular channel is the fifteenth opening, and the ending end is the sixteenth opening. The fifteenth and sixteenth openings are adjacent or close to each other. The two ends of the strap are located outside the annular channel, starting from the fifteenth and sixteenth openings respectively. When the user pulls the two ends of the strap, the annular channel is brought together as a whole, closing the fifth entrance. Conversely, when the user does not pull the strap, the annular channel is unfolded to open the fifth entrance. In some embodiments, the fifteenth and sixteenth openings are merged into one large opening.

[0293] In some embodiments, after the second filter bag is gathered, the user can lift the second filter bag with the strap for subsequent operations, or directly lift the gathered second filter bag; or, in some embodiments, the annular channel is provided with at least two seventeenth openings, so that the user can pull out the strap through the two seventeenth openings to lift the second filter bag, or the user can pull out the strap through the seventeenth opening to bring the annular channel together as a whole to gather the fifth inlet.

[0294] In some embodiments, such as Figures 44 to 48 As shown, the drawstring mechanism 2117 also includes at least one limiting member 21172 for limiting the filter bag and / or the drawstring. For example, as Figure 43 As shown, when the fifth inlet is in the deployed state, the annular channel is also in the deployed state, and the contact length between the strap and the annular channel is the first length; as Figure 44 As shown, after the strap gathers the fifth inlet, the annular channel is confined to the gathered state by operating the limiting member. At this time, the contact length between the strap and the annular channel is limited to the second length, which is less than the first length, thereby confining the fifth inlet to the gathered state.

[0295] In some embodiments, such as Figure 47 , Figure 48 As shown, the limiting member 21172 includes a first telescopic member 211721 and a second telescopic member 211722. The relative movement of the first telescopic member and the second telescopic member enables the annular channel to switch between an expanded state and a retracted state, or enables the contact length between the strap and the annular channel to switch between a first length and a second length, thereby enabling the fifth inlet to switch between an open state and a retracted state.

[0296] Further, in some embodiments, the first telescopic member includes a first segment 21172a and a second segment 21172b, the cross-sectional area of ​​the first segment is larger than that of the second segment, the first segment has a first through hole 21172c, and the second segment has a second through hole 21172d. The first telescopic member and the second telescopic member have the same structure. An elastic element 21173 (e.g., a spring, a sheet) is sleeved on the second segment of the first telescopic member and the second telescopic member, with one end of the elastic element connected to the first segment of the first telescopic member and the other end connected to the first segment of the second telescopic member. One end of the strap is inserted sequentially through the first through hole of the first telescopic member and the second through hole of the second telescopic member, and the other end of the strap is inserted sequentially through the first through hole of the second telescopic member and the second through hole of the first telescopic member. By pressing the elastic element, the user causes the overlapping area between the first through hole of the first telescopic member and the second through hole of the second telescopic member, as well as the overlapping area between the first through hole of the second telescopic member and the second through hole of the first telescopic member, to change. When the aforementioned overlapping area increases, the strap can move freely between the first through hole and the second through hole. When the aforementioned overlapping area decreases, the strap is restricted from moving, thereby allowing the strap to switch between the first length and the second length.

[0297] In the above embodiment, since the strap has a certain thickness, when the limiting member is in the unfolded state, the two ends of the strap are limited by part of the first through hole and part of the second through hole, and the strap cannot move at this time; at this time, the strap restricts the two telescopic members from continuing to move in opposite directions; when it is necessary to pull the strap to close and open the fifth inlet, the first telescopic member and the second telescopic member are pressed to increase the overlapping area of ​​the first through hole of the first telescopic member and the second through hole of the second telescopic member. At the same time, the overlapping area of ​​the first through hole of the second telescopic member and the second through hole of the first telescopic member increases accordingly, and the strap can move within the first through hole and the second through hole to adjust the size of the fifth inlet.

[0298] In some embodiments, such as Figure 46 As shown, the limiting member also includes a fixing member 211723, which is provided on the first telescopic member and the second telescopic member. For example, the fixing member is provided on the second segment. Since the first telescopic member and the second telescopic member can move relative to each other, the limiting member has an unfolded state and a compressed state. When the limiting member moves from the compressed state to the unfolded state, the first telescopic member and the second telescopic member move in opposite directions, that is, the two first segments move away from each other to release the spring. At the same time, the fixing member restricts the first telescopic member and the second telescopic member from continuing to move in the opposite direction. At this time, the strap is restricted from moving. When the limiting member moves from the unfolded state to the compressed state, the two telescopic members move towards each other, that is, the two first segments move closer to each other to compress the spring. At this time, the strap can move freely between the first through hole and the second through hole.

[0299] The detachable and fixed connections mentioned in this application can be made by using at least one of the following methods: threaded connection, magnetic connection, snap-fit ​​connection, key pin connection, locking connection, plug connection, grooved connection, screw connection, etc.
