[0006] This invention belongs to the field of cleaning equipment technology, and particularly relates to a pool robot and cleaning system. Background Technology

[0007] With the widespread use of swimming pools in homes, commercial spaces, and public areas, the demand for cleaning pool bottoms, walls, waterlines, and surfaces continues to increase. Manual cleaning methods, due to their high labor intensity, low efficiency, and the significant impact of human factors on cleaning quality, are gradually failing to meet the requirements of high-frequency, high-standard cleaning. Therefore, swimming pool cleaning robots are gradually becoming the mainstream cleaning equipment, and related technologies are relatively mature.

[0008] Such devices typically include a main body and a first filter box located inside it, which is used to filter out debris carried in the liquid. However, when the debris in the first filter box accumulates to a certain amount, existing technologies generally require users to remove the robot from the water, manually open the outer shell, and remove the filter box for emptying and cleaning. If stubborn dirt is found adhering to the filter screen or the inner wall of the box, users also need to perform additional brushing or rinsing. The entire process is not only time-consuming and laborious, resulting in a poor user experience, but also suffers from incomplete cleaning, easy cross-contamination, and low cleaning efficiency.

[0009] Therefore, a new technical solution is needed to address the problems existing in the aforementioned technologies. Summary of the Invention

[0010] This invention aims to solve the problem of low cleaning efficiency in existing pool robots. In view of this, this invention provides a pool robot, comprising: a first main body; a first filter box, at least partially disposed within the first main body; the first filter box includes: a first inlet, at least partially disposed at the bottom of the first filter box; and a third opening disposed on the first filter box; when the first filter box is held within the first main body, pool liquid flows into the first filter box through at least the first inlet and is filtered by the first filter box, forming a first water path for the pool robot to clean the pool liquid; when the first filter box is held within the first main body, cleaning liquid flows into the first filter box, and liquid used to rinse debris from the first filter box flows out through the third opening, forming a cleaning water path for cleaning the first filter box.

[0011] In some embodiments, the present invention also provides a cleaning system, comprising: a base station and a pool robot, wherein the pool robot is the pool robot described above; the base station comprises: a base station body; and a first nozzle; when the pool robot stops on the base station body, the first nozzle extends into the first body and sprays liquid into the first filter box to rinse the first filter box.

[0012] Compared with existing technologies, the pool robot and cleaning system described in this invention have the following advantages:

[0013] This application sprays liquid into the first filter box of the pool robot through the first nozzle, effectively flushing away the garbage and dirt attached to the filter screen. The resulting dirty liquid flows out through the third opening, thus automatically completing the cleaning of the filter box and the separation of dirty liquid without human intervention, significantly improving cleaning efficiency and cleaning effect.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0072] This application provides a cleaning system, as shown in Figures 1 to 31. The cleaning system includes a pool robot 1000 and a base station 2000. The base station is used at least to clean the first filter box 1051 of the pool robot, so that the garbage in the first filter box is transferred from the pool robot or temporarily stored in the base station.

[0073] In one embodiment, as shown in FIG29, the base station includes a base station body 20001, a second cleaning component 2170, and a third receiving cavity 2054; wherein, the second cleaning component includes at least one first nozzle 2173, which is disposed on the base station body. The first nozzle cleans the first filter box by spraying liquid onto the first filter box; when the pool robot stops on the base station body, the first nozzle is used to spray liquid onto the first filter box to rinse the garbage inside the first filter box and the garbage attached to the wall surface of the first filter box, thereby cleaning the garbage inside the first filter box; at the same time, the garbage inside the first filter box falls into the third receiving cavity, thereby transferring the garbage inside the first filter box into the third receiving cavity.

[0074] In one embodiment, as shown in FIG29, the base station further includes a second filter box 21102 for receiving and further filtering debris from the first filter box. The second filter box may be disposed within a third receiving cavity.

[0075] Pool robots are used to perform tasks such as cleaning, disinfection, and rescue in a target area. The target area can be any water-containing area where the robot can move. For example, the target area can include, but is not limited to, swimming pools, water tanks, oil wells, and sewers. The following description uses a swimming pool (or water tank) as an example. For a swimming pool, it includes at least a pool bottom and pool walls.

[0076] For pool robots, they can be powered by a built-in rechargeable battery or by an external cable. If the pool robot has bottom and wall movement capabilities, it can clean the pool bottom and walls. If it has bottom, wall, and surface movement capabilities, it can clean the pool bottom, walls, and surface. A pool robot with movement capabilities is considered an autonomous walking pool robot, requiring no user pushing or pulling.

[0077] This application discloses a swimming pool robot, as shown in Figures 1 to 4 and Figures 10 to 13, comprising: a first body 1001; and a first filter box, at least partially disposed within the first body. The first filter box includes: a first inlet 10511a, at least partially disposed on the bottom of the first filter box; and a third opening 10531 disposed on the first filter box. When the first filter box is held within the first body, pool liquid flows into the first filter box through the first inlet and is filtered by the first filter box, forming a first water path for the swimming pool robot to clean the pool liquid; when the first filter box is held within the first body, cleaning liquid flows into the first filter box, and liquid used to rinse debris from the first filter box flows out through the third opening, forming a cleaning water path for cleaning the first filter box.

[0078] In one embodiment, the third opening and the first inlet are the same opening. The first filter box also includes a first baffle 10511c for opening or closing the first inlet. When the first baffle opens the first inlet, the first water path or the cleaning water path operates. In this embodiment, the first baffle needs to be driven by a motor to open or close the first inlet.

[0079] In this embodiment, the first filter box has only one opening at the bottom, which serves to simultaneously handle water intake and sludge discharge, thus simplifying the structure while ensuring cleaning effectiveness.

[0080] In another embodiment, as shown in Figures 3 and 4, the first inlet and the third opening are different openings. The first filter box further includes: a first baffle for opening or closing the first inlet; and a first bottom cover 1054 for opening or closing the third opening. When the first bottom cover closes the third opening and the first baffle opens the first inlet, the first water path can operate; when the first bottom cover opens the third opening, the cleaning water path can operate.

[0081] In this embodiment, the first baffle is made of soft rubber. When the first water channel is running, the first baffle opens the first inlet under the suction action of the suction component 1060. When the cleaning water channel is running, the first baffle can keep the first inlet closed, or there can be a gap between the first baffle and the first inlet.

[0082] In this embodiment, when the first bottom cover closes the third opening and the first baffle opens the first inlet, the liquid in the pool enters the first filter box through the first inlet and is filtered. The filtered liquid is discharged outside the first main body, thereby forming a first water path for cleaning the pool liquid. When the first bottom cover opens the third opening, the cleaning liquid enters the first filter box to rinse the garbage in the filter box. The garbage is discharged through the third opening, thereby forming a cleaning water path for cleaning the first filter box.

[0083] In some embodiments, as shown in Figures 4 and 30, at least a portion of the third opening is located on the bottom of the first filter box. For example, in some embodiments, the third opening is located entirely on the bottom of the first filter box, or a portion of the third opening is located on the bottom of the first filter box and a portion is located on the side of the first filter box.

[0084] In some embodiments, as shown in Figures 6 and 7, the first filter box further includes a twelfth opening 10536, which is a different opening from the first inlet. Cleaning liquid enters the first filter box through the twelfth opening to rinse away debris inside the first filter box and flows out through the third opening.

[0085] In some embodiments, as shown in Figures 4 and 5, the pool robot further includes a fourth inlet 1016 disposed on the first body. The fourth inlet is adjacent to and communicates with the twelfth opening, so that cleaning liquid flows from the fourth inlet and the twelfth opening into the first filter box. The cleaning liquid flows sequentially through the fourth inlet, the twelfth opening, the first filter box, and the third opening to form a cleaning water path.

[0086] In some embodiments, a fourth inlet is provided on the side of the first body, and a twelfth opening is provided on the side of the first filter box.

[0087] In some embodiments, as shown in Figures 2, 3, 4, and 5, the pool robot further includes a liquid inlet 1030, which includes at least one second inlet 1032, located on the front or rear side of the first body. A second inlet 10511b is located on the side of the first filter box. The second inlet is adjacent to or near the second inlet and communicates with it, at least for allowing debris on the liquid surface to flow into the first filter box. The second inlet serves as a fourth inlet and a twelfth opening.

[0088] The second inlet is also equipped with a second baffle 10511d, which is used to open or close the second inlet.

[0089] In other embodiments, as shown in Figures 7 and 11, the pool robot further includes a pick-up / placement port 1017, at least partially located on the top of the first body, for inserting or removing the first filter box from the first body. The first filter box also includes an eleventh opening 10532, at least partially located on the top of the first filter box. The eleventh opening and the pick-up / placement port are adjacent to or near each other and communicate with each other, allowing cleaning liquid to flow into the first filter box from both the pick-up / placement port and the eleventh opening. The pick-up / placement port serves as a fourth inlet, and the eleventh opening serves as a twelfth opening.

[0090] In some embodiments, the first filter box may not have the aforementioned twelfth opening. The cleaning liquid flows directly into the first filter box from the first filter screen 1055 to rinse the debris in the first filter box and flows out from the third opening.

[0091] This application employs various configuration designs for the inlet structure, slag discharge structure, and coordinated control method of the first baffle / first bottom cover of the first filter box. This allows the pool robot to selectively operate the first water path for pool liquid filtration and the cleaning water path for cleaning the first filter box within the same filter box structure. By considering whether to include a twelfth opening, whether the first and third inlets are combined, and the drive or adaptive opening method of the baffle, a flexible balance between structural simplification and functional diversification is achieved.

[0092] In some embodiments, as shown in Figures 1, 3, and 11, the pool robot includes: a liquid inlet; a liquid outlet 1040, including a first outlet 1041, at least partially disposed on the top of the first main body; and a suction assembly disposed within the first main body. Under the action of the suction assembly, the liquid in the pool flows sequentially through the liquid inlet, the first filter box, the suction assembly, and the liquid outlet to form a first water path or a second water path.

[0093] The swimming pool robot disclosed in this application includes a first body, a liquid inlet, a liquid outlet, a suction assembly, and a first filter box. The first filter box, which is at least partially located in the first body, is used to filter the dust-laden liquid that enters it, so as to clean the bottom, walls, waterline, or surface of the swimming pool. The swimming pool robot also has a cleaning water path for automatically or semi-automatically cleaning the first filter box, so as to flush and discharge the garbage in the first filter box when the robot returns to the base station or under specific working conditions.

[0094] In some embodiments, as shown in Figures 3 and 4, the liquid inlet section includes at least a first inlet 1031, and the liquid outlet section includes at least one first outlet. The first inlet, the first filter box, the suction assembly, and the first outlet 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 some embodiments, there is one first outlet. Alternatively, in other embodiments, there are multiple first outlets. For example, there are two, three, or more first outlets.

[0095] In other embodiments, the liquid inlet includes at least a second water inlet, and the liquid outlet includes at least a first water outlet; the second water inlet, the first filter box, the suction assembly, and the first water outlet are sequentially connected to form a second water path for cleaning the water surface and water line. In some embodiments, as shown in Figures 1 and 5, the first body includes a front portion 10011 and a rear portion 10012. The second water inlet is located on the front or rear portion of the first body.

[0096] In some embodiments, a first baffle is provided at the first water inlet or the first inlet; a second baffle is provided at the second water inlet or the second inlet. When the pool robot is cleaning the water surface, the first baffle is in a closed state to prevent liquid in the pool from entering the first filter box through the first water inlet, and the second baffle is in an open state to allow liquid to enter the first filter box through the second water inlet and the second inlet. When the pool robot is cleaning the pool bottom or pool wall, the second baffle is in a closed state to prevent liquid from entering the first filter box through the second water inlet, and the first baffle is in an open state to allow liquid to enter the first filter box through the first water inlet. That is, when cleaning the water surface, the first baffle is in a closed state and the second baffle is in an open state; when cleaning the pool wall or pool bottom, the first baffle is in an open state and the second baffle is in a closed state.

[0097] In some embodiments, the liquid inlet includes at least one first water inlet, which is located on the bottom of the first body and is connected to a first inlet.

[0098] In one specific example, the first inlet is located on the bottom of the first main body, and the first inlet is located on the bottom of the first filter box. The first inlet is connected to the first inlet, 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 bottom cover does not synchronously drive the movement of the first inlet and the first inlet; that is, the movement of the first bottom cover is independent of the first inlet and the first inlet.

[0099] In this embodiment, since the first inlet is located at the bottom of the first filter box and is staggered from the third opening in the horizontal direction, the first inlet occupies a part of the bottom area of ​​the first filter box, which limits the area of ​​the third opening. This makes it difficult for large-sized debris in the first filter box to fall into the second filter box from the third opening, or large-sized debris may get stuck at the third opening, affecting the cleaning effect of the liquid sprayed by the first nozzle on the debris in the first filter box.

[0100] Therefore, in order to increase the area occupied by the third opening at the bottom of the first filter box and to allow large debris inside the first filter box to be discharged outside, in some embodiments, as shown in FIG4, the liquid inlet includes at least one first water inlet, which is the same opening as the first inlet, and is located at the bottom of the first filter box. The first body also includes a seventh opening 1033, located at the bottom of the first body, for at least exposing the bottom of the first filter box to the outside.

[0101] In some embodiments, the first filter box includes: a first frame 1053; a third opening, at least partially disposed on the bottom of the first frame; a first filter screen, at least disposed on the side of the first frame; and a first bottom cover, movably disposed on the first frame, for opening or closing the third opening. A first water inlet is disposed on the first bottom cover. A seventh opening is used to expose the first bottom cover to the outside environment.

[0102] In this embodiment, the third opening can occupy the entire area or most of the area of ​​the bottom of the first filter box, thereby increasing the area of ​​the third opening. This allows large-sized debris in the first filter box to be discharged from the third opening and fall into the second filter box when the first base opens the third opening.

[0103] In a specific example, as shown in Figures 6 and 7, the first filter box includes a first frame, a first bottom cover, and a first filter screen. At least a portion of the third opening is located on the bottom of the first frame; alternatively, the entire bottom of the first frame forms a bottom opening as the third opening. The first filter screen is located on at least one side wall of the first frame to form a filter surface for filtering liquid entering the first filter box. The first bottom cover is rotatably mounted on the first frame to open or close the third opening. For example, the first bottom cover opens the third opening by rotating outward from the first frame, outward from the pool robot, or outward from 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 example, when the third opening is open, since the first bottom cover is located outside the first frame, it does not obstruct debris from entering the first filter box, allowing debris to be discharged from the first filter box through the third opening, thus improving the cleaning effect of the sprayed liquid from the first nozzle on the first filter box. The first bottom cover can be automatically opened in a clean state by a flow of clean water, a drive mechanism, or a control component, thereby achieving automatic drainage of the first filter box.

[0104] In some embodiments, as shown in Figures 3 and 5, the first main body includes: a first receiving cavity 10013, a first filter box disposed within the first receiving cavity and forming a first gap 10582 between the filter box and the first receiving cavity; and a second receiving cavity 10014, separated from the first receiving cavity. The first receiving cavity and the second receiving cavity are connected through at least one second drain port 10013a, and a suction assembly is disposed within the second receiving cavity. Liquid in the pool flows sequentially through the inlet section, the first filter box, the first gap, the second drain port, the suction assembly, and the outlet section to form a first water path or a second water path.

[0105] The first inlet, the first filter box, the first gap, the second drain, the suction assembly, and the first outlet are sequentially connected in fluid order to form a first water path. The second inlet, the first filter box, the first gap, the second drain, the suction assembly, and the first outlet are sequentially connected in order to form a second water path.

[0106] In some embodiments, as shown in FIG4, the second receiving cavity includes a first cavity 10014a and a second cavity 10014b, which are spaced apart. The suction assembly includes a main motor 10611 and a main impeller 10612, the main motor driving the main impeller to rotate. The main motor is disposed in the second cavity, and the main impeller is disposed in the first cavity. The output shaft of the main motor extends into the first cavity and is connected to the main impeller. The liquid outlet communicates with the first cavity.

[0107] Furthermore, in some embodiments, both the first cavity and the second cavity are located outside the first receiving cavity.

[0108] In some embodiments, as shown in Figures 3 and 4, the pool robot further includes a cover 1015, which is detachably fixed to the control box. The cover is specifically a first cavity, with one end located on the side wall of the first receiving cavity and covering or surrounding the second drain port so that the second drain port communicates with the first cavity. The other end of the cover is connected to the first water outlet. The portion of the second receiving cavity outside the cover serves as the second cavity. The control box is located within the second cavity, and the main motor of the main water pump 1061 is located within the control box. The output shaft of the main motor extends out of the control box and into the cover, connecting to the main impeller.

[0109] Regarding the second cavity, in some embodiments, all internal cavities outside the first cavity of the first body, except for the first receiving cavity, can serve as the second cavity. For example, in some embodiments, the first dust chamber 1052 is disposed within the first body, and the inner cavity of the first dust chamber serves as the first receiving cavity. The cavity formed between the inner wall of the first body and the outer wall of the first dust chamber then serves as the second receiving cavity. The cavities other than the cover are considered the second cavity. The first body is the outer shell of the pool robot.

[0110] In other embodiments, the first cavity is located inside the first receiving cavity, and the second cavity is located outside the first receiving cavity.

[0111] In some embodiments, the suction assembly includes at least one main water pump; in other embodiments, there are multiple suction assemblies, each corresponding to at least one outlet.

[0112] In some embodiments, as shown in Figures 2, 8, 9, and 31, the first body further includes: at least one third drain port 10013b, disposed on the first receiving cavity; at least one first drain port 105, disposed on the bottom and / or side of the first body, both the third drain port and the first drain port communicating with the second receiving cavity; and a third baffle 10013c, movably disposed outside the first receiving cavity, for closing or opening the third drain port. When the pool robot leaves the pool in an inclined posture, the third baffle opens the third drain port under the gravity of the liquid in the first receiving cavity. The first receiving cavity, the third drain port, the second receiving cavity, and the first drain port are sequentially fluidly connected to form a third waterway for rapid drainage.

[0113] The third baffle can be made of soft rubber. With this setup, when the pool robot is cleaning in the pool, the suction assembly creates negative pressure in the first receiving cavity, causing the third baffle to adhere to the outside of the first receiving cavity and close the third drain outlet. When the pool robot leaves the pool, the suction assembly stops operating, the negative pressure in the first receiving cavity is removed, and the suction effect on the third baffle is canceled. As the pool robot leaves the pool at an angle, the gravity of the liquid in the first receiving cavity causes the third baffle to rotate and open the third drain outlet. In other words, when the first or second water channel is running, the third baffle closes the third drain outlet.

[0114] In some embodiments, as shown in FIG1, the pool robot further includes a fourth handle 122, which the user can grip to lift the pool robot out of the pool and allow it to exit the water; or, the user can carry the pool robot on the shore. For example, the fourth handle is located on the front of the first body, and there are multiple first drain ports, some located on the rear of the first body and some located on the bottom of the first body. When the user lifts the fourth handle, the pool robot exits the water at an angle. At this time, the first drain port on the rear of the first body is located below the first drain port on the bottom of the first body. After the liquid in the first receiving cavity enters the second cavity through the third drain port, it can be quickly discharged from the first drain port on the rear of the first body, further accelerating the drainage speed of the pool robot during the exiting process.

[0115] In some embodiments, as shown in FIG3, when the first water inlet is located on the first bottom cover, since the top of the first main body has a pick-up and drop-out port and the bottom of the first main body has a seventh opening, both of which are connected to the first receiving cavity, the first receiving cavity forms a through cavity on the first main body. A first gap is formed between the outer side of the first filter box and the first receiving cavity, and the first gap is connected to the outside. Due to the existence of the first gap, when the pool robot cleans the pool bottom, pool wall, waterline, or water surface, under the action of the suction component, some of the liquid in the pool directly enters the main water pump from the first gap and is finally discharged from the first main body through the first water outlet to form the fifth water channel.

[0116] In this embodiment, some liquid enters the main impeller of the main water pump directly through the first gap without being filtered by the first filter box, resulting in poor cleaning effect of the pool robot; at the same time, the garbage carried in the liquid will remain at the main impeller of the main water pump, which can easily cause the impeller of the main water pump to get stuck and not rotate normally.

[0117] Therefore, in some other embodiments, as shown in FIG3, the pool robot further includes at least one first interceptor 10581. The first interceptor is disposed in the first gap and located below the second drain port to cut off or block the liquid in the pool from entering the main impeller of the main water pump through the first gap and the second drain port, and from the first outlet. This ensures that when the pool robot cleans the pool bottom, pool wall, waterline or water surface, the liquid in the pool enters the first filter box through the first inlet or the second inlet.

[0118] The first interceptor is detachably or fixedly mounted on the first frame or the first receiving cavity. In some embodiments, if the user's requirements for cleaning effect are not high, the first interceptor may not be provided in the first gap. In this case, when the pool robot performs cleaning of the pool bottom, pool walls, waterline, or water surface, the liquid in the pool is discharged from the pool robot through the fifth water channel. For example, when the pool robot is cleaning the pool wall, some liquid is discharged from the pool robot through the fifth water channel. This portion of liquid can exert a thrust on the pool robot towards the pool wall, making the pool robot stick tightly to the pool wall and preventing the pool robot from falling off the pool wall.

[0119] In some embodiments, as shown in Figures 11 to 14, the pool robot further includes at least one propulsion mechanism. The propulsion mechanism includes: a surface propulsion assembly 116 having a first propulsion water path for at least driving the pool robot to walk on the water surface, the first propulsion water path being different from the cleaning water path; and / or a lateral propulsion assembly 115 having a second propulsion water path for at least driving the pool robot to move laterally, the second propulsion water path being different from the cleaning water path.

[0120] This application provides at least one propulsion mechanism to a pool robot, in addition to the cleaning water path, to provide additional driving force for the robot, enabling position adjustment, posture correction, or movement along a specific path. The propulsion mechanism includes a surface propulsion component and / or a lateral propulsion component. The first propulsion water path of the surface propulsion component and the second propulsion water path of the lateral propulsion component are different from the cleaning water path and do not participate in the filtration and cleaning process of the pool liquid during operation. This avoids interference with filtration efficiency caused by propulsion movements and significantly improves the pool robot's maneuverability at the water surface, waterline, and pool walls.

[0121] In some embodiments, as shown in FIG11, the water surface propulsion assembly includes: a third flow channel 116a, one of the two openings of the third flow channel serving as a first fluid inlet and the other as a first fluid jet outlet; and a first thruster 116f disposed within the third flow channel. Liquid flows sequentially through at least the first fluid inlet, at least a portion of the first thruster, and the first fluid jet outlet to form a first propulsion waterway.

[0122] In a specific example, the water propulsion assembly includes a third flow channel and a first thruster. The first thruster includes a fifth motor 116b and a first impeller 116c. The two ends of the third flow channel are a thirteenth opening 116d and a fourteenth opening 116e, respectively. One of the thirteenth and fourteenth openings serves as a first fluid inlet, and the other as a first fluid ejection port. The fifth motor and the first impeller are located within the third flow channel. When the fifth motor drives the first impeller to rotate in the forward direction, liquid flows into the third flow channel from the thirteenth opening, passes through at least a portion of the first thruster, and then is ejected from the fourteenth opening, forming a sixth water path. The ejected liquid generates a first driving force on the pool robot. The direction of the first driving force is opposite to the direction of the liquid ejected from the fourteenth opening, thereby propelling the pool robot forward on the water surface, in the water, or on the pool wall. Conversely, the fifth motor drives the first impeller to rotate in the opposite direction. Liquid flows into the third channel from the fourteenth opening, passes through at least part of the first thruster, and then sprays out from the thirteenth opening to form the seventh water channel. The sprayed liquid generates a second driving force on the pool robot. The direction of the second driving force is opposite to the direction of the liquid sprayed from the thirteenth opening, that is, the direction of the second driving force is opposite to the direction of the first driving force, thus pushing the pool robot backward.

[0123] For example, in some embodiments, the stator and rotor of the fifth motor are connected by ceramic bearings, and the rotor and motor housing are connected by ceramic bearings.

[0124] In some embodiments, there are two water surface propulsion components, each disposed on one side of the pool robot. The pool robot has a forward direction, which is from the rear of the pool robot to the front of the pool robot.

[0125] In some embodiments, the third flow channel extends generally in the forward direction. That is, the third flow channel is a generally straight flow channel.

[0126] Alternatively, in other embodiments, the third flow channel includes at least one first sub-flow channel 116a1 and at least one second sub-flow channel 116a2, wherein the first sub-flow channel extends generally along the forward direction, and the second sub-flow channel extends generally along a second direction intersecting the forward direction. That is, the third flow channel is a non-linear flow channel, a generally polygonal flow channel, or a curved flow channel.

[0127] In some embodiments, the water propulsion assembly is located on the side of the first body and above the walking mechanism 1071.

[0128] In other embodiments, as shown in FIG11, the water surface propulsion assembly is disposed on the side of the first body and located within the walking mechanism. Each walking mechanism includes two wheels (i.e., a first wheel 1171 and a second wheel 1172), a track 117, and an outer cover plate 1174. The track is wound around the two wheels. The outer cover plate is disposed on the first body to at least cover the two wheels. The outer cover plate has a first grille 11741 and a second grille 11742, one of which serves as a first fluid inlet and the other as a first fluid jet outlet. A third flow channel is formed between the side of the first body and the outer cover plate, and the third flow channel is located between the two wheels.

[0129] In some embodiments, as shown in Figures 13 and 14, the lateral propulsion assembly includes: a fourth flow channel 115a, with a first opening 115d and a second opening 115e at its two ends, one of which serves as a second fluid inlet and the other as a second fluid jet outlet, at least the second fluid jet outlet being located on the side of the pool robot; and a second thruster 115f disposed within the fourth flow channel. Liquid flows sequentially through the second fluid inlet, at least a portion of the second thruster, and the second fluid jet outlet to form a second propulsion waterway.

[0130] In one specific example, the lateral propulsion assembly includes a fourth flow channel and a second propeller. The second propeller includes a second motor 115b and a second impeller 115c. At least a portion of the fourth flow channel is located on the side of the first body. One end of the fourth flow channel has a first opening, and the other end has a second opening. One of the first and second openings serves as a second fluid inlet, and the other end serves as a second fluid jet outlet. Both the second motor and the second impeller are located within the fourth flow channel.

[0131] When the second motor drives the second impeller to rotate, liquid enters the fourth flow channel from the second fluid inlet, passes through the second impeller, and is ejected from the second fluid jet nozzle. The water jet from the second fluid jet nozzle is directed away from the side of the first main body. This jet of water generates a second thrust on the pool robot, which provides at least a lateral thrust component to the pool robot, enabling it to stay close to the pool sidewall as it moves along the water surface; and to move laterally along the waterline on the pool wall to clean the waterline; and the pool robot... When a person is at the bottom of the pool, the robot walks along the edge of the pool, close to the sidewall, to clean the pool bottom. It also drives the pool robot to move laterally on the water surface, in the water, on the pool bottom, and on the pool walls to adjust its position, allowing it to return to the support surface of the carrier from any position on the water surface or pool wall; or, the pool robot can return to the pool shore from any position on the water surface, pool wall, or pool bottom (or, return to a preset docking point on the pool shore, i.e., fixed-point docking), ready for the user to retrieve it from the pool. The lateral direction is perpendicular to the robot's direction of travel.

[0132] In some embodiments, the second fluid inlet is connected to the first receiving cavity. In this embodiment, the first receiving cavity is used to contain liquid filtered by the first filter box, one end of the fourth flow channel forms the second fluid inlet, and the other end forms the second fluid jet outlet. When the lateral propulsion assembly is working, the second propeller drives the filtered liquid from the first receiving cavity into the fourth flow channel. The liquid flows sequentially through the second fluid inlet, the second propeller, and is ejected from the second fluid jet outlet to form the second propulsion water path. During this process, the suction force in the first receiving cavity is increased by the suction action of the second propeller. The second propeller continuously draws out the liquid in the first receiving cavity, creating a negative pressure in the first receiving cavity. This makes it easier for the liquid in the pool to enter the first filter box for filtration through the liquid inlet, improving the liquid inlet efficiency of the first or second water path without the need for additional suction components.

[0133] Alternatively, in other embodiments, as shown in Figures 2, 20, 28, and 31, the pool robot further includes at least one first drain port, at least partially located on the bottom and / or side of the first body, communicating the second receiving cavity with the outside. A second fluid inlet communicates with the second receiving cavity. In this example, the second receiving cavity is used to temporarily store liquid inside the pool robot, but does not include liquid filtered by the first filter box. When the lateral propulsion assembly is activated, the second propeller drives the liquid in the second receiving cavity into the fourth flow channel, and the liquid is ejected through the second fluid jet port and discharged outside the pool robot.

[0134] Alternatively, in other embodiments, the fourth flow channel is arranged laterally along the first body to penetrate both sides of the pool robot, with the second fluid inlet and the second fluid jet outlet respectively located on both sides of the pool robot. In this example, both the second fluid inlet and the second fluid jet outlet are directly connected to the liquid in the pool. When the lateral propulsion assembly operates, the liquid in the pool enters the fourth flow channel from the second fluid inlet located on one side, passes through the second thruster, and is ejected from the second fluid jet outlet on the other side. The jetting water generates lateral thrust on the pool robot.

[0135] In some embodiments, the pool robot further includes two locomotion mechanisms, respectively disposed on both sides of the first body. Each locomotion mechanism includes: two locomotion wheels (i.e., a first locomotion wheel and a second locomotion wheel); a track wound around the two locomotion wheels; and an outer cover plate disposed on the first body to at least cover the two locomotion wheels. The two locomotion wheels, the track, and the outer cover plate form a first region 1173. At least a second fluid injection port is disposed on the outer cover plate of one of the locomotion mechanisms. At least a portion of a fourth flow channel is located within the first region.

[0136] In some embodiments, the second fluid inlet is located on the outer cover plate of another traveling mechanism, and the two ends of the fourth flow channel are respectively located in the first region of the two traveling mechanisms, so that the two ends of the fourth flow channel penetrate through the outer cover plates of the two traveling mechanisms.

[0137] The pool robot typically has left-edge and / or right-edge modes. In this embodiment, the left-edge mode refers to the pool robot's left edge being close to or adjacent to the edge of the target area (e.g., the pool), and the right-edge mode refers to the pool robot's right edge being close to or adjacent to the edge of the target area. For example, in the left-edge mode, the second fluid jet is located on the right side wall of the first body to generate a second thrust towards the left of the pool robot. Conversely, in the right-edge mode, the second fluid jet is located on the left side wall of the first body to generate a second thrust towards the right of the pool robot.

[0138] In some embodiments, as shown in Figures 15 to 19, the pool robot further includes a water path auxiliary component 118 to increase the liquid output of the liquid outlet. The water path auxiliary component includes: a third inlet 1181 disposed on the first receiving cavity; and a seventh baffle 1182, one end of which is rotatably disposed on the first receiving cavity and located outside the first receiving cavity. The seventh baffle opens or closes the third inlet by rotation. When the pool robot is at the bottom of the pool, the seventh baffle closes the third inlet; when the pool robot crawls from the bottom of the pool to the pool wall or is on the pool wall, the seventh baffle opens the third inlet. The third inlet, the first gap, the suction component, and the liquid outlet are sequentially fluidly connected to form an auxiliary water path.

[0139] In this embodiment, the water path auxiliary component is structurally isolated from the first water path and the second water path, and functionally works in conjunction with or independently of the cleaning water path. It is used to provide auxiliary liquid that has not been filtered by the first filter box to the liquid outlet under specific working conditions, so that the liquid outlet's drainage capacity does not completely depend on the unobstructed state of the first filter box, thereby enhancing the adhesion stability of the pool robot under pool wall or waterline working conditions.

[0140] The area outside the first receiving cavity is the second receiving cavity, which is connected to the outside. The liquid in the pool first enters the second receiving cavity, and then enters the first gap through the second receiving cavity and the third inlet, without being filtered by the first filter box.

[0141] In this example, no motor is used to drive the seventh baffle to rotate. The seventh baffle can open or close the third water inlet mainly because of the swimming pool robot's posture. When the swimming pool robot is at the bottom of the pool, the first receiving cavity is in a roughly vertical position, and the seventh baffle, under its own gravity, can remain in the closed state of the third water inlet. When the swimming pool robot is on the pool wall, the first receiving cavity is in a roughly horizontal position. Due to the change in the posture of the first receiving cavity, the seventh baffle rotates under its own gravity to open the third water inlet.

[0142] In some embodiments, there are two water channel auxiliary components, which are respectively disposed on two sides of the first receiving cavity along the lateral direction of the pool robot. For example, the forward direction of the pool robot is approximately perpendicular to the lateral direction of the pool robot. Along the forward direction of the pool robot, the first receiving cavity includes a first side 10013d ​​and a second side 10013e that are distributed opposite to each other; along the lateral direction of the pool robot, the first receiving cavity includes a third side 10013f and a fourth side 10013g that are distributed opposite to each other. The water channel auxiliary components are disposed on the third side and the fourth side. The aforementioned second drain outlet is disposed on the second side, and the third drain outlet is disposed on the second side.

[0143] In some embodiments, the seventh baffle opens or closes the third water inlet by rotating on the outer wall of the first receiving cavity. The upper end of the seventh baffle is rotatably disposed on the first receiving cavity. The water channel auxiliary assembly also includes at least one counterweight 1183 disposed on the lower end of the seventh baffle. The lower end of the seventh baffle has a mounting cavity in which the counterweight is embedded. The seventh baffle rotating on the outer wall of the first receiving cavity means that the rotation axis of the seventh baffle is approximately perpendicular to the side of the first receiving cavity. During rotation, the seventh baffle remains in contact with or close to the outer wall of the first receiving cavity, without moving away from it, thus minimizing the space required for rotation. If the rotation axis of the seventh baffle is approximately parallel to the side of the first receiving cavity, the seventh baffle rotates away from the side of the first receiving cavity to open the third water inlet. This would require sufficient space between the outer side of the first receiving cavity and the outer shell of the first main body to allow the seventh baffle to rotate, resulting in a larger size for the first main body and a less compact structure for the pool robot. As an alternative embodiment, the rotation axis of the seventh baffle can be substantially parallel to the side of the first receiving cavity, but a space needs to be formed between the outer shell of the first body and the first receiving cavity to allow the rotation of the seventh baffle to open or close the third inlet.

[0144] When the pool robot is on the pool wall, the liquid discharged from the outlet by the suction assembly creates a first thrust towards the pool wall, allowing the robot to stay close and preventing it from falling off. However, when the first filter box becomes clogged, the liquid entering the filter box cannot enter the first gap and is discharged from the outlet by the suction assembly. This reduces the amount of liquid discharged, thus decreasing the first thrust towards the pool wall and making it easier for the robot to fall off. In this embodiment, by setting up a water path auxiliary assembly, when the pool robot is on the pool wall, the seventh baffle opens the third inlet, and the liquid is discharged from the outlet through the auxiliary water path, increasing the discharge volume and thus increasing the first thrust of the liquid discharged from the outlet on the pool robot, especially when the first filter box is clogged, preventing the robot from falling off the pool wall.

[0145] This application, through a multi-waterway isolation architecture, enables the independent operation of the cleaning waterway, the rapid drainage structure, and the propulsion waterway, achieving a comprehensive performance improvement in stable sludge suction, continuous filtration, rapid drainage, reliable propulsion, and self-cleaning of the filter box. This significantly enhances the operational efficiency and reliability of the pool robot in various scenarios such as pool bottom, pool wall, water surface, and waterline.

[0146] In some embodiments, as shown in FIG22, the pool robot further includes at least one downward-looking detection component 119 for detecting obstacles or the environment below the bottom of the pool robot. The downward-looking detection component includes: a distance sensor 1191 disposed within the first body of the pool robot; a first channel 1192 disposed on the bottom of the first body and extending into the first body; the distance sensor communicates with the outside through the first channel, such that there is a gap between the distance sensor and the bottom of the first body.

[0147] The distance sensor is used to detect the positions of steps, basking platforms, slopes, etc., encountered by the pool robot during operation, providing good detection information for the robot's movement. The distance sensor can be an ultrasonic sensor, an infrared sensor, an image acquisition device, etc.

[0148] Distance sensors have blind spots; when the distance between the sensor and an object is less than a preset value, the sensor may not receive a signal, or the received signal may be of low accuracy. By setting up a first channel and positioning the distance sensor at a certain distance from the bottom of the main body, the pool robot can accurately detect objects even when they are close below, allowing for a faster response. Simultaneously, the first channel can be used to concentrate the signal, directing it more effectively in a specific direction and improving detection performance.

[0149] In some embodiments, the upper end of the first channel is narrower than the lower end. The wider lower end of the first channel can expand the range of the transmitted or received signal, while the narrower upper end can make the signal more concentrated and improve the detection effect.

[0150] Furthermore, in some embodiments, the first channel is approximately conical in shape from its upper end to its lower end. Compared to structures such as square or polygonal holes, the conical shape of the first channel avoids signal reflection and disturbance on the sidewalls of the channel, further improving the detection effect.

[0151] In some embodiments, the first channel can also cooperate with the limiting component on the base station to limit / position the pool robot, ensuring that the pool robot stops at the designated position on the base station.

[0152] In some embodiments, as shown in FIG20, the pool robot further includes a scraper 109 and a fourth handle. The fourth handle is disposed on the first body. The scraper includes at least a first segment 1091 and two second segments 1092. The first segment is disposed on the first bottom cover; the two second segments are disposed on the bottom of the first body and are located on the outer sides of the first bottom cover, so that the scraper surrounds the outer periphery of the first water inlet. The first water inlet is closer to the fourth handle than the first segment. The second segments are closer to the fourth handle than the first segment.

[0153] In this embodiment, a fourth handle is located on the first main body for the user to lift or move the pool robot; a scraper is located at the bottom area of ​​the first main body to gather or guide trash as the pool robot moves along the pool bottom or wall, thereby improving the efficiency of trash entering the first water inlet. Combined with the optimized design of the first water inlet, the first section, and the second section relative to the fourth handle, the scraper forms a barrier or guide structure in front of the pool robot's direction of travel.

[0154] In some embodiments, a first segment is fixedly disposed on the lower surface of a first bottom cover and rotates with the first bottom cover; a second segment is fixedly disposed on the bottom of a first body and does not rotate with the first bottom cover. The two second segments are symmetrically distributed on both sides of the central axis of the pool robot and located to the left and right outer sides of the first segment. In some examples, the shape of the second segment can be arc-shaped or guide-shaped to guide the dust-laden water or debris collected from the areas on both sides of the pool robot to the first water inlet located in the center, thereby effectively widening the coverage width of a single cleaning without increasing the size of the first water inlet.

[0155] In some embodiments, as shown in FIG21, the first segment and / or the second segment includes: a mounting strip 1093; at least two scrapers 1094 fixed to the mounting strip, with a gap formed between adjacent scrapers. The mounting strip is disposed on the first body or the first bottom cover.

[0156] The scraper blades surround the outer periphery of the first inlet, serving two purposes: firstly, preventing liquid behind the blades from flowing towards the inlet; and secondly, increasing the suction force in the area in front of the blades, concentrating the suction at the inlet and making it easier for liquid in front of the blades to enter the first filter box. Furthermore, when the pool robot moves along the pool bottom or wall, some debris in front of the blades may not be able to enter the first filter box in time. The blades, moving with the robot, can push this debris closer to the inlet and into the filter box. Gaps are formed between adjacent blades. When the blades encounter large obstacles, they can increase the deformation of the blades, allowing them to overcome obstacles without getting stuck.

[0157] In some embodiments, the scraper is mounted on the first body or the first bottom cover through a combination of a limiting groove, a limiting through hole, and a limiting rod. In some embodiments, the interference fit between the limiting rod and the limiting through hole and the limiting groove allows the scraper to be reliably fixed without screws or additional fasteners; in some embodiments, the limiting rod includes a cylindrical portion and a conical or frustum-shaped transition portion, making it easy to press in during installation, not easy to loosen during use, and quick to disassemble by applying upward force during maintenance or replacement.

[0158] In other embodiments, part of the first segment is located on the first bottom cover and part is located on the first main body; or, only the first segment is provided without the second segment; or, the number, length, or shape of the first and second segments are adjusted according to cleaning needs. None of these structural changes affect the basic function of the scraper to gather debris around the first water inlet and improve cleaning efficiency.

[0159] In some embodiments, as shown in Figures 22, 24, and 25, the pool robot further includes: a locking mechanism 1080, which locks the first bottom cover onto the first frame when the third opening is closed; and an unlocking mechanism 7003, which drives the locking mechanism to move to release the locking mechanism from locking the first bottom cover.

[0160] In this embodiment, the pool robot includes a locking mechanism and an unlocking mechanism. When the first bottom cover closes the third opening, the locking mechanism locks the first bottom cover onto the first frame to keep the first bottom cover closed. The unlocking mechanism, under the action of a driving force, drives the locking mechanism to move, thereby releasing the locking mechanism from the first bottom cover and allowing the first bottom cover to move relative to the first frame, thus opening the third opening. The driving force can be a manual force applied by the user or a driving force applied by the unlocking structure mounted on the base station; the specific source of the external force is not limited in this specification.

[0161] In some embodiments, the unlocking mechanism includes at least: at least one second unlocking member 70033, at least partially disposed within the pool robot; and a third clearance opening 1001j, disposed on the bottom of the first body. The second unlocking member has a force-receiving end 700331 and a pushing end 700332, and the third clearance opening exposes the force-receiving end to the outside. The force-receiving end moves under the action of a driving force, causing the pushing end of the second unlocking member to drive the locking mechanism to move, thereby releasing the locking mechanism from locking the first bottom cover.

[0162] In some embodiments, the locking mechanism locks the first bottom cover onto the first frame by extending in a generally horizontal direction. A second unlocking member is rotatably disposed within a second receiving cavity. The first receiving cavity has a connecting hole 10013h. The force-receiving end rotates under the action of a driving force, and the pushing end extends through the connecting hole into the first receiving cavity to push the locking mechanism to retract, thereby releasing the locking mechanism from locking the first bottom cover.

[0163] In one specific embodiment, the locking mechanism includes a first limiting hole 10801, a first locking member 10802, and a fourth elastic member 10803. One of the first locking member and the first limiting hole is disposed on the first frame, and the other is disposed on the first bottom cover. The fourth elastic member applies its elastic force to the first locking member, forcing the first locking member to tend to extend, so as to remain within the first limiting hole and lock the first bottom cover onto the first frame; correspondingly, the unlocking mechanism is used to drive the first locking member to retract, so as to exit the first limiting hole.

[0164] For example, the first limiting hole is provided on the first frame, and the first locking member is telescopically or slidably provided on the first bottom cover; the fourth elastic member is a compression spring, one end of the fourth elastic member is provided on one end of the first locking member, and the other end is provided on the first bottom cover; the compression spring applies a biasing force to the first locking member in the direction of the first limiting hole, so that the other end of the first 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 the first bottom cover remains closed with the third opening closed.

[0165] In a specific example, the unlocking mechanism includes a second unlocking member and a fifth elastic member 70034. The second unlocking member is rotatably disposed within a second receiving cavity, with its force-bearing end exposed to the outside, and its pushing end extending into the first receiving cavity through a connecting hole. When the force-bearing end rotates under external force, the second unlocking member rotates as a whole, causing its pushing end to rotate through the connecting hole into the first limiting hole, thereby pushing the first locking member to retract, and thus the first locking member to exit the first limiting hole. The biasing force generated by the fifth elastic member tends to keep the pushing end of the second unlocking member outside the first limiting hole. After the locking mechanism unlocks, the driving force at the force-bearing end of the second unlocking member is removed, and under the action of the fifth elastic member, the second unlocking member rotates in the opposite direction to exit the first limiting hole, and the pushing end of the second unlocking member returns to its original position outside the first limiting hole. The connecting hole is located in the first receiving cavity, for example, in the first dust chamber. One end of the fifth elastic member abuts against at least a portion of the second unlocking member, and the other end abuts against the outer wall of the first dust chamber. In this embodiment, the fifth elastic element can be a torsion spring or a compression spring; alternatively, it can also be a tension spring.

[0166] In some embodiments, the pool robot further includes a charging receiver 1020 disposed on the bottom of the first body, for receiving external electrical energy when the pool robot docks at a preset position (e.g., a charging dock or a preset position on a base station) to charge the first battery pack inside the pool robot. The charging receiver includes at least a conductive structure or an electromagnetic coupling structure, and can receive electrical energy through contact charging or wireless charging, which is not limited in this specification.

[0167] In some embodiments, as shown in FIG28, the charging receiver includes two second charging plates 10201, each of which has a downwardly protruding charging bump, one charging bump serving as the positive electrode and the other as the negative electrode. When the user lifts the pool robot from the pool, the robot carries liquid. Because the charging bump is located on the second charging plate, the liquid is less likely to form a water film at the bump, thus the bump serving as the positive electrode is less prone to electrolysis, improving its charging performance. Furthermore, having only one charging bump on each second charging plate avoids the occurrence of electrical sparks. If two or more charging bumps are provided, and one of them cannot contact the external charging plate, at least one of the remaining charging bumps will generate electrical sparks due to excessive current. However, having only one charging bump means it either contacts the external charging plate for charging or does not, thus preventing charging but avoiding the occurrence of electrical sparks.

[0168] In some embodiments, the bottom of the first main body of the pool robot integrates multiple functional units such as a downward detection component, an unlocking mechanism, a scraper, a water inlet structure, a charging receiver, and a drainage structure. These functional units are staggered along the forward and lateral directions of the pool robot at the bottom of the first main body to avoid mutual interference.

[0169] In some embodiments, there are two unlocking mechanisms and one locking mechanism, with one unlocking mechanism corresponding to one locking mechanism. A third clearance opening is provided on the bottom of the first body, which exposes the force-bearing end of the second unlocking member of the unlocking mechanism to the outside. There are two third clearance openings, located on the outside of the seventh opening or the two sides of the first bottom cover, respectively.

[0170] There are two downward-facing detection components. The bottom of the corresponding first main body has two first channels, each corresponding to a distance sensor. Along the forward direction of the pool robot, the first channels are located behind the main roller brush 1131 at the front of the pool robot.

[0171] The two second sections of the scraper are distributed on both sides of the seventh opening or the first bottom cover. The first section and the two second sections roughly form a flared structure around the outer periphery of the first water inlet. Along the forward direction of the pool robot, the second section is located between the first channel and the third clearance opening; along the lateral direction of the pool robot, the second section is located between the third clearance opening and the seventh opening or the first bottom cover. The third clearance opening is located outside the second section, mainly to avoid affecting the negative pressure zone formed by the scraper in front of the second water inlet, and also to make the structure of the pool robot compact.

[0172] As shown in Figures 23 and 28, an inspection port 1001f5 is also provided on the bottom of the first main body for repairing or replacing the liquid circulation section 1104 of the buoyancy and submersion mechanism. There are two inspection ports, located on the outer sides of the seventh opening or the first bottom cover, respectively, along the forward direction of the pool robot. The inspection ports are located behind the second section and behind the third clearance opening.

[0173] The two second charging pads of the charging receiver and the first drain port are located behind the seventh opening or the first bottom cover, and behind the inspection port. In some embodiments, multiple first drain ports are provided at the bottom of the first body for draining liquid inside the robot. The first portion of the first drain ports is located between the second charging pads and the seventh opening or the first bottom cover, and this portion of the first drain ports is also located in the area between two second charging pads. The second portion of the first drain ports is located between two second charging pads. The third portion of the first drain ports is located behind the second charging pads, thereby preventing the liquid discharged from the first drain ports from affecting the second charging pads, especially when charging the pool robot.

[0174] In some embodiments, as shown in Figures 26 and 27, the pool robot further includes a floating and diving mechanism, which is used at least to keep the pool robot afloat on the liquid surface. The floating and diving mechanism includes at least one first float cavity 1101, a float cavity pump 1102, and at least one gas circulation section 1103. The first float cavity is disposed within a first body, at least partially located at the front and at least partially located at the rear of the first body. The float cavity pump is in fluid communication with the first float cavity. The gas circulation section is in communication with the first float cavity and is located at the front of the first body.

[0175] When the gas flow section is above the liquid surface or waterline, outside air enters the first float chamber through the gas flow section under the action of the float pump, increasing the volume of gas inside the first float chamber and causing the pool robot to float on the liquid surface. Under the action of the float pump, the gas inside the first float chamber is discharged through the gas flow section, reducing the volume of gas inside the first float chamber and causing the pool robot to sink from the liquid surface to the bottom of the pool. Alternatively, the pool robot can move along the pool wall; when the pool robot reaches the waterline, the gas flow section is above the liquid surface or waterline. The pool robot may also include a third propeller, which drives the pool robot directly from the bottom of the pool to the liquid surface, ensuring that the gas flow section is above the liquid surface or waterline.

[0176] In some embodiments, the pool robot includes a floating and diving mechanism disposed within a first main body, used to adjust the overall buoyancy of the pool robot, thereby switching the pool robot between an underwater state and a floating state on the water surface. Specifically, by adjusting the ratio of gas volume to liquid volume within the first floating cavity of the floating and diving mechanism, the balance state of buoyancy and gravity acting on the pool robot is changed, thereby enabling the pool robot to float or dive.

[0177] Furthermore, in some embodiments, when the first float cavity is made of a rigid material, the buoyancy and submersion mechanism further includes at least one liquid flow section. The liquid flow section communicates with the first float cavity and is located within the first main body. Under the action of the float cavity pump, water is drawn in or pumped into the first float cavity from the liquid flow section. The liquid entering the first float cavity forces the gas within it out of the gas flow section, thereby reducing the volume of gas in the first float cavity and increasing the volume of liquid within it, causing the pool robot to sink from the liquid surface. Conversely, under the action of the float cavity pump, water in the first float cavity is pumped out from the liquid flow section, allowing outside air to be drawn into the first float cavity from the gas flow section, thus increasing the volume of gas within the first float cavity.

[0178] It should be noted that the surfacing and diving mechanism in this application cannot directly switch from underwater to the surface. The pool robot needs to walk from the bottom of the pool to the surface or waterline, for example, by climbing a wall or by being driven by a third thruster, so that the gas circulation part is exposed above the surface. Only then can the pool robot float on the surface of the liquid and maintain a roughly horizontal posture by inflating the first floating cavity.

[0179] In some embodiments, as shown in FIG26, the first float cavity includes a first sub-float cavity 11011 and a second sub-float cavity 11012. The gas flow section is connected to the first sub-float cavity via a first pipe, the first and second sub-float cavities are connected via a second pipe, the second sub-float cavity and the float pump are connected via a third pipe, and the float pump and the liquid flow section are connected via a fourth pipe. A spring may be fitted on at least one of the first, second, third, and fourth pipes to facilitate bending deformation and support the pipes. Further, in some embodiments, the end of the first pipe away from the gas flow section is located on the top of the first sub-float cavity and is connected to it. Since the gas in the first sub-float cavity mainly concentrates in the top portion of the first sub-float cavity, connecting this end of the first pipe to the top of the first sub-float cavity allows the gas in the first sub-float cavity to be discharged from the first sub-float cavity more quickly, or allows the gas to flow from the gas flow section into the first sub-float cavity more quickly. Preferably, this end of the first conduit is located on top of the first sub-float cavity and near the front of the first sub-float cavity.

[0180] In some embodiments, there may be two first float cavities, each corresponding to a float pump. The two first float cavities may share a gas flow section, or each may correspond to a separate gas flow section. Each float cavity corresponds to a liquid flow section, and the two liquid flow sections are distributed on both sides of the first bottom cover.

[0181] The bottom of the first body is provided with at least one inspection port, and an inspection cover 1001f6 is provided on the inspection port. The liquid flow part is located inside the inspection port. When the inspection cover is opened, the liquid flow part is exposed, which facilitates maintenance or replacement of the liquid flow part through the inspection port.

[0182] In some embodiments, as shown in Figure 28, inspection ports are provided on both sides of the bottom shell 1001f along the width direction of the seventh opening. Each inspection port is equipped with an openable inspection cover. In the non-maintenance state, the inspection cover covers the inspection port; in the maintenance state, the inspection cover opens to expose the inspection port, thereby allowing maintenance or replacement of the internal liquid flow section. The inspection cover can be sealed by means of screw fixing, snap connection, or waterproof adhesive strip. The inspection port is designed to be directly opposite the liquid flow section of the buoyancy and descent mechanism inside the pool robot. When it is necessary to unclog or inspect the liquid flow section, maintenance personnel or users only need to open the corresponding inspection cover, and the liquid flow section is fully exposed, allowing for direct cleaning or inspection with tools without any complex disassembly work, greatly improving the maintainability of the cleaning system.

[0183] In some embodiments, to prevent the charging receiver from being affected by liquids on the pool robot, especially liquids discharged through the liquid flow section, further protective measures are provided on the pool robot. For example, an eighth baffle 1001f8 is provided inside the bottom shell of the pool robot on both sides of the seventh opening in the lateral direction. The eighth baffle extends generally in the lateral direction, with one end connected to the edge of the seventh opening and the other end connected to the inner sidewall of the bottom shell, thereby forming a barrier inside the robot that physically separates the seventh opening area, the inspection port area, and the charging interface area. This barrier can effectively prevent liquids from directly reaching the charging receiver.

[0184] However, a completely sealed enclosure could prevent water from draining into the access area, potentially causing water accumulation. Therefore, a drain outlet 1001f9 is provided on the side wall of the bottom shell. This outlet is located close to the access area and away from the charging receiver. This ensures that even if a small amount of water accumulates in the access area, it will flow through the drain outlet to the outside of the pool robot, preventing it from accumulating inside the compartment and overflowing over the eighth baffle to reach the charging receiver.

[0185] This application also discloses a cleaning system, including a base station and a pool robot. The pool robot is the aforementioned pool robot. The base station includes a base station body and a first nozzle. When the pool robot stops on the base station body, the first nozzle extends into the first body and sprays liquid into the first filter box to rinse the first filter box.

[0186] In a specific example, when the pool robot stops on the base station body, the first nozzle passes through the fourth inlet and the twelfth opening in sequence and extends into the first filter box to spray liquid into the first filter box to rinse the first filter box.

[0187] The base station disclosed in this application can be used on land, for example, by placing it on the bank of a pool or on the ground. In this case, the base station is in an air environment, and the pool robot can automatically get out of the pool and walk onto the base station. For example, the base station also includes a support component, one end of which is attached to the base station body, and the other end extending below the surface of the water in the pool, allowing the pool robot to walk from the pool to the support component and then back to the base station body. Alternatively, the pool robot can be manually carried onto the base station body by a user.

[0188] When the base station is used on shore or on the ground, the first filter box is in the air, and the first nozzle sprays water at least to the side and / or bottom of the first filter box to rinse the side and / or bottom of the first filter box, not only flushing the garbage inside the first filter box out of the first filter box, but also washing away the garbage attached to the side and / or bottom of the first filter box.

[0189] When the base station is placed on the shore or on the ground, the water source for cleaning the first filter box can be municipal water from the user's home. For example, water from a tap. Since municipal water is pumped to the user's tap, the base station may or may not need to have a first water pump. Alternatively, the water source for cleaning the first filter box can be other types of water, such as water from a pool or river. In this embodiment, the base station needs to include at least one first water pump, which draws water from the pool or river to the first nozzle, causing the nozzle to spray water.

[0190] The liquid filtered by the second filter can be discharged into the user's sewer or outdoor lawn; alternatively, it can be discharged into a pool for reuse. Furthermore, the base station also includes a second water pump, which is used to pump the liquid filtered by the second filter out of the base station to accelerate the discharge of the liquid from the base station.

[0191] The base station disclosed in this application can also be placed inside a pool or in a placement area connected to the pool. For example, the base station can be placed on a raised platform inside the pool. For example, the raised platform can be a sun deck or steps within the pool, wherein the sun deck and steps can be separated in the pool, or the sun deck can serve as a step surface of the steps. Alternatively, a recessed placement area can be provided on the pool bank, and the placement area can be connected to the pool through an opening in the pool wall, where the base station can be installed. Alternatively, the base station can be installed on the pool wall; or on the bottom of the pool; or it can be placed in other locations within the pool. When the base station is installed inside the pool or in a placement area, a pool robot can automatically walk back to the base station body from the pool; or, the pool robot can be manually carried to the base station body by a user.

[0192] The base station also includes a drainage channel for discharging the liquid filtered by the second filter box outside the base station; one end of the drainage channel connects to the third receiving cavity, and the other end serves as the final drain outlet. In scenarios where the base station is placed in a pool or placement area, when the pool robot is stationary on the base station body, if the final drain outlet is at least partially or completely below the first liquid level in the pool, the base station also includes at least one second water pump for pumping the liquid filtered by the second filter box out of the base station. If the final drain outlet is above the first liquid level in the pool, the base station may or may not have a second water pump.

[0193] If the base station is placed in a pool or within a designated area, when the pool robot is stationary on the base station, if the first liquid level in the pool is lower than or roughly level with the fourth opening of the base station, the first filter box is located above the fourth opening and is therefore in the air. Alternatively, if the first liquid level in the pool is lower than the bottom of the first filter box, the first filter box is also in the air. The first nozzle sprays liquid onto the first filter box to clean it. The cleaning effect of the first nozzle on the first filter box is roughly the same as if the base station were on land or ground. In other words, the first nozzle sprays water onto the first filter box located in the air to clean the debris inside and adhering to the inner wall of the first filter box.

[0194] The main body of the pool robot is provided with at least one first water outlet, and at least part of the first water outlet is located on the top of the main body. When the pool robot cleans the liquid in the pool, the liquid filtered by the first filter box is discharged out of the pool robot through the first water outlet.

[0195] In scenarios where the base station is placed in a pool or within a designated area, when the pool robot is stationary on the base station, if the first liquid level in the pool is between the bottom of the first filter box and the first outlet, at least a portion of the side of the first filter box is positioned below the first liquid level, creating a second liquid level within the first filter box. This second liquid level can be higher, lower, or equal to the first liquid level. For example, when the pool robot is stationary on the base station, before the first nozzle and second water pump are running, the first liquid level in the pool is between the bottom of the first filter box and the first outlet; or, when at least one of the first nozzle and second water pump is running, the first liquid level in the pool is between the bottom of the first filter box and the first outlet.

[0196] For example, for ease of description, the side portion of the first filter box located below the second liquid surface is referred to as the first side portion, and the side portion of the first filter box located above the second liquid surface is referred to as the second side portion. Since the first side portion is located below the second liquid surface and the second side portion is located above the second liquid surface, that is, the second side portion is in the air environment, when the first nozzle sprays water onto the first side portion and the second side portion, the first impact force of the water sprayed onto the first side portion is greatly reduced, while the second impact force of the water sprayed onto the second side portion is not reduced. The first impact force is less than the second impact force. Therefore, the water sprayed by the first nozzle can clean the garbage attached to the second side portion, but cannot clean the garbage attached to the first side portion.

[0197] Therefore, in order to clean the debris attached to the first side of the first filter box, in this embodiment, the liquid in the first filter box is continuously drawn into the second filter box by operating the aforementioned second water pump (e.g., turning it on or increasing the operating parameters). The liquid is then filtered by the second filter box, making the outflow of water from the first filter box greater than the flow rate of liquid sprayed from the first nozzle into the first filter box (i.e., the inflow of water into the first filter box); or the drainage volume of the second water pump per unit time is greater than the spray volume of the first nozzle per unit time, causing the second liquid level in the first filter box to drop. This keeps the side of the first filter box continuously exposed above the second liquid level, i.e., in the air environment, thereby reducing the proportion of the first side on the side of the first filter box. This allows the water flow sprayed by the first nozzle to clean the second side above the second liquid level.

[0198] For example, in some embodiments, by operating the second water pump, the second liquid level in the first filter box is lowered to or below the third opening of the first filter box. This means that most of the sides of the first filter box are above the second liquid level, allowing the water jet from the first nozzle to clean most of the sides of the first filter box. For instance, if the second water pump is off before adjusting the second liquid level, the controller turns it on when adjustment is needed. Alternatively, if the second water pump is running before adjusting the second liquid level, the controller increases its operating parameters when adjustment is required. Furthermore, the base station also includes a sensor to detect the second liquid level, allowing the controller to control the second water pump to start or adjust its operating parameters based on the sensor's detection signal.

[0199] Alternatively, in some embodiments, the operation of the second water pump adjusts the height of the second liquid level in the first filter box to a preset height; once the second liquid level reaches the preset height, it is kept at the preset height to facilitate the first nozzle spraying liquid to clean the side of the first filter box.

[0200] For example, a first filter screen is provided on the side of the first filter box to form a first filter surface. Debris easily adheres to the first filter screen, so when the first nozzle cleans the side of the first filter box, it primarily cleans the first filter screen. The second water pump adjusts the height of the second liquid level to ensure that the first filter screen is positioned above the second liquid level, i.e., in the air environment. Alternatively, in some embodiments, a first filter screen may or may not be provided at the bottom of the first filter box. If a first filter screen is provided at the bottom of the first filter box, the second water pump adjusts the second liquid level to ensure that the first filter screen at the bottom of the first filter box is also positioned above the second liquid level, facilitating the cleaning of debris adhering to the first filter screen when the first nozzle sprays liquid onto the bottom of the first filter box.

[0201] In other words, if most or all of the first filter screen is below the second liquid surface, the liquid in the first filter box needs to be sucked away by the operation of the second water pump, so that most of the first filter screen is above the second liquid surface, that is, the first filter screen is in the air environment, which makes it easier for the first nozzle to spray liquid onto the first filter screen to wash away the garbage attached to the first filter screen.

[0202] Furthermore, if the base station is placed in a pool or designated area, when the pool robot is stationary on the base station, if the first liquid level in the pool is higher than the first outlet, when the second water pump operates to adjust the height of the second liquid level, the liquid in the pool will flow back through the first outlet into the first filter box. This increases the amount of water entering the first filter box, requiring the water pump to operate at higher parameters to lower the second liquid level so that most of the first filter screen is above the second liquid level. Therefore, in actual use, it is best to keep the first liquid level below the first outlet; however, it can also be above the first outlet. Alternatively, if the base station is placed in a pool or designated area, the second liquid level in the first filter box can be adjusted without using the second water pump; the first nozzle can also spray water onto the sides and bottom of the first filter box to clean it, although the cleaning effect is relatively weaker, it can still clean most of the debris inside the first filter box.

[0203] In some embodiments, if the base station is placed inside a pool or in a designated area, the pool robot is charged wirelessly by the base station.

[0204] In some embodiments, if the base station is placed in a pool or within a designated area, the water source for cleaning the first filter box can be liquid from the pool. In this case, the base station also includes the aforementioned first water pump to pump the liquid from the pool to the first nozzle. Alternatively, the water source for cleaning the first filter box can be municipal water from the user's home, such as tap water. In this embodiment, the liquid filtered by the second filter box can be discharged back into the pool for reuse; alternatively, it can be pumped into the user's sewer or onto the user's outdoor lawn by the operation of the second water pump.

[0205] Furthermore, regardless of whether the base station is used on land or on the ground, or placed in a pool or designated area, the base station also includes a pressurization component to ensure that the water jet from the first nozzle is high-pressure. The pressurization component can be located in the waterway between the clean water source and the first nozzle. For example, the pressurization component includes, but is not limited to, a booster pump, a water hammer pump, a pressure tank, a mechanical pressurization device, an elevated water tank, etc., or the water pressure of the jet from the first nozzle can be increased by reducing the size of the nozzle on the first nozzle.
