[0005] This invention belongs to the technical field of swimming pool cleaning equipment, and particularly relates to a cleaning system. Background Technology

[0006] Currently, to address the cleaning needs of pool bottoms, sidewalls, and surfaces, pool robots have gradually replaced manual cleaning as the mainstream solution. These devices typically consist of a main body and a first filter box inside, used to filter debris carried in the liquid. However, when debris accumulates in the first filter box to a certain level, current technology generally requires 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 adheres to the filter screen or the inner wall of the box, users also need to perform additional scrubbing or rinsing. This entire process is not only time-consuming and laborious, resulting in a poor user experience, but also suffers from incomplete cleaning, cross-contamination, and low cleaning efficiency. Summary of the Invention

[0007] In view of this, the present invention provides a cleaning system designed to solve the problem of low cleaning efficiency of pool robots in the prior art.

[0008] This application discloses a cleaning system, including a base station and a pool robot. The base station includes: a base station body having a third receiving cavity, a fourth opening, and at least one drainage component; a second cleaning component including at least one first nozzle; and a second filter component, at least partially disposed within the third receiving cavity. The fourth opening is at least used to allow liquid carrying waste to flow to the second filter component. The drainage component is at least used to discharge the liquid filtered by the second filter component out of the base station body. The pool robot includes: a first body; a first filter box, at least partially disposed within the first body; and a third opening on the first filter box, the third opening being at least used to discharge waste from the first filter box. The pool robot rests on the base station body, and the first nozzle, the first filter box, the second filter component, and the drainage component are sequentially fluidly connected to form a first cleaning water path for cleaning the first filter box.

[0009] The cleaning system of this application, through the coordinated design of jet rinsing and filtration recovery, enables the water flow to form a continuous closed loop throughout the entire process of "cleaning-filtration-discharge". The first nozzle sprays liquid into the first filter box of the pool robot, effectively flushing away the debris and dirt attached to the filter screen. The resulting waste liquid then enters the second filter component through the third and fourth openings, realizing an automatic transfer and re-filtration process. Thus, the cleaning of the filter box and the separation of waste liquid are automatically completed without human intervention, significantly improving cleaning efficiency and cleaning effect.

[0015] like Figures 1-24 As shown, this application discloses a cleaning system, including: a base station 2000 and a pool robot 1000.

[0016] The base station includes: a base station body 20001 having a third receiving cavity 2054, a fourth opening 2055, and at least one drainage assembly; a second cleaning assembly 2170 including at least one first nozzle; and a second filter assembly 2110, at least partially disposed within the third receiving cavity. The fourth opening is at least used to allow liquid carrying waste to flow to the second filter assembly. The drainage assembly is at least used to discharge the liquid filtered by the second filter assembly out of the base station body.

[0017] The pool robot includes: a first body 1001; a first filter box 1051, at least partially disposed within the first body; and a third opening 10531 on the first filter box, the third opening being used at least to discharge waste from the first filter box.

[0018] The pool robot stops on the base station body, and the first nozzle, the first filter box, the second filter component and the drainage component are connected in sequence to form the first cleaning water channel for cleaning the first filter box.

[0019] The cleaning system disclosed in this application integrates a third receiving chamber, a second filter assembly, and a second cleaning assembly to construct a compact and streamlined automatic cleaning and wastewater discharge system. After the pool robot completes its cleaning task, it automatically returns to the base station or is placed on it by the user. The second cleaning assembly activates and sprays cleaning liquid into the pool robot's first filter box. The sprayed liquid, under impact, peels off dirt adhering to the filter screen, chamber walls, or the inside of the first filter box, and entrains it into the water flow, forming wastewater carrying impurities. Subsequently, under the influence of gravity and fluid guidance, the wastewater flows into the third receiving chamber through a fourth opening in the base station. At this point, the inlet of the second filter assembly aligns with the fourth opening, allowing the wastewater to directly enter the second filter assembly for solid-liquid separation. Waste is trapped in the second filtration component, while clean water passes through the filter screen and settles to the bottom of the third containment chamber. It is then quickly discharged outside the base station through the drainage component. Depending on actual needs, the discharged liquid can be directed to the sewer, lawn, or returned to the swimming pool. This avoids liquid accumulation in the third containment chamber and enables wastewater to be discharged or recycled. The system can flexibly adapt to different environments. The entire process does not require user intervention and achieves fully automatic closed-loop operation from cleaning, collection, filtration to discharge. This not only improves the self-cleaning efficiency of the pool robot but also enhances the base station's own anti-fouling and self-maintenance capabilities.

[0020] In some examples of this application, such as Figure 10 As shown, the first filter box includes: a first frame 1053; a third opening, at least on the bottom of the first frame; a first filter screen 1055, at least on the side and / or bottom of the first frame; and a first bottom cover 1054, rotatably disposed on the first frame, for opening or closing the third opening.

[0021] In some embodiments, 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 sidewall of the first frame to form a filter surface for filtering liquid entering the first filter box; alternatively, in addition to having the first filter screen on the sidewall, the first frame may also have a first filter screen on at least one of its top and bottom surfaces to form a filter surface. The first bottom cover is movably located on the first frame to open or close the third opening.

[0022] In some embodiments of this application, such as Figure 3 , Figure 4The second filter assembly includes: a second filter box 21102, the second filter box having a third inlet 21101, the third inlet and the fourth opening being in communication.

[0023] In some embodiments, the second filtration assembly includes at least a second filter box having at least one filter surface and at least one third inlet for filtering liquids and debris entering therein, so that debris is trapped inside the second filter box, while liquids are discharged from the base station body after being filtered by the filter surface. When the pool robot is placed on the base station body, the third inlet can be aligned and connected with the fourth opening of the base station, so that debris and liquids in the first filter box enter the second filter box through the fourth opening and the third inlet under the action of gravity.

[0024] In some embodiments, when the pool robot stops at the cleaning position of the base station body, the first nozzle sprays liquid onto the first filter box, and at least a portion of the first nozzle is located above the second filter box.

[0025] After the first bottom cover of the first filter box opens to the third opening, the garbage in the first filter box and the liquid sprayed into the first filter box by the first nozzle enter the second filter box through the fourth opening and the third inlet. The garbage is retained in the second filter box, and the liquid is discharged from the base station body after being filtered by the second filter box. This process concentrates or temporarily stores the garbage in the first filter box into the second filter box, thus completing the automatic cleaning of the first filter box.

[0026] In some embodiments, at least a portion of the fourth opening is located directly above at least a portion of the third inlet, so that water carrying waste can flow through the fourth opening and the third inlet and fall into the second filter box.

[0027] Furthermore, the area of ​​the fourth opening is smaller than that of the third inlet, so that all the garbage entering the fourth opening can fall into the second filter box.

[0028] Alternatively, when the base station is placed on a horizontal surface, the first projection of the fourth opening on the horizontal surface is located within the second projection of the third entrance on the horizontal surface, so that all the garbage entering the fourth opening can fall into the second filter box.

[0029] In some embodiments of this application, the second filter box includes: a second frame 2112 having at least one hole; a third inlet, at least partially disposed on the top of the second frame; and at least one second filter screen 2113 disposed on the second frame, at least covering the hole to form a second filter surface.

[0030] In the above embodiments, the second filter screen may be disposed on the bottom of the second frame, or on the side of the second frame, or both on the bottom and side of the second frame.

[0031] In some other embodiments, the second filter cartridge includes: a cartridge body having at least one opening, with at least a portion of a third inlet located on the top of the cartridge body; and a first filter bag, at least partially located within the cartridge body. The first filter bag has an open end with a sixth inlet (not shown), which communicates with the fourth opening. The open end of the first filter bag is located on the third inlet. The cartridge body is in communication with a drainage assembly.

[0032] In other embodiments, the second filter box itself is a filter bag structure, meaning the first filter bag is directly used as the second filter box. The first filter bag can be a disposable filter bag or a filter bag that can be reused multiple times.

[0033] In some embodiments of this application, such as Figure 5 , Figure 6 As shown, the second filter assembly also includes a first tray 211041, disposed within the third receiving cavity. A second filter box is disposed on the first tray. At least one second drain outlet 211042 is provided on the first tray, and the second drain outlet communicates with the drainage assembly. The first nozzle, first filter box, second filter box, first tray, and drainage assembly are sequentially fluidly connected to form a first clean water path.

[0034] In some embodiments, at least a portion of the first tray is located below the second filter box. The liquid filtered by the second filter box first enters the first tray, then flows from the second drain outlet to the drainage assembly, and is discharged outside the base station through the drainage assembly.

[0035] In some embodiments, the second drain outlet is provided on the first side of the first tray. A seventh guide portion 211043 is provided at the bottom of the first tray, such that the bottom of the first tray slopes downward from the side away from the second drain outlet toward the side closer to the first side, so that the clean water naturally converges to the second drain outlet along the inclined surface under the action of gravity.

[0036] In some embodiments of this application, such as Figure 3 , Figure 5 , Figure 6 As shown, the drainage assembly includes a first drain outlet 2120 and a drainage channel 2000261. The first drain outlet is located on the side of the third receiving cavity. The first drain outlet and the second drain outlet are connected or interlocked. The drainage channel is located on the base station body and outside the third receiving cavity. The drainage channel is connected to the second drain outlet, allowing the liquid treated by the second filter box and the first tray to be discharged from the base station body.

[0037] In some embodiments, such as Figure 5As shown, the drainage assembly also includes a first transition chamber 2000262. The second drain outlet is located above the drainage channel. Through the first transition chamber, water discharged from the second drain outlet first enters the first transition chamber and then enters the drainage channel. In some embodiments, a third guide portion 2000263 is provided at the bottom of the first transition chamber. For example, the third guide portion is arranged in a spiral inclined shape, so that when liquid flows out from the first tray, it can immediately slide along the spiral inclined surface and quickly concentrate in the drainage channel, thereby increasing the water flow speed and reducing the possibility of liquid staying on the plane.

[0038] In some embodiments, the second filter box is a first filter bag, which is disposed within a first tray that supports the first filter bag. For example, in some embodiments, the first tray is a box with an opening at the top, and the third inlet of the first filter bag is fitted over the opening at the top of the box. The first filter bag is located inside the box, and the box supports the first filter bag. A second drain outlet is provided at the bottom of the box to allow liquid inside the box to drain out of the base station.

[0039] In some embodiments, the first tray is detachably disposed within the third receiving cavity. For example, the first tray is pull-out disposed within the third receiving cavity, allowing the user to remove the entire tray for cleaning when residual liquid or debris needs to be removed. In some embodiments, when both the first tray and the second filter box are pull-out disposed within the third receiving cavity, the first tray and the second filter box can be configured as a synchronously pull-out or independently pull-out structure.

[0040] In some embodiments of this application, the second filtration assembly further includes a second filter bag, at least partially disposed within the second filter box. The second filter bag has an open end with a fifth inlet communicating with a fourth opening. The open end of the second filter bag is located at a third inlet. The second filter box is used to filter the liquid filtered by the second filter bag. The first nozzle, the first filter box, the second filter bag, the second filter box, and the drainage assembly are sequentially fluidly connected to form a first clean water path.

[0041] The dual-layer filtration system, consisting of a second filter bag and a second filter box, further enhances the filtration efficiency of the waste. Furthermore, the second filter bag is detachably located within the second filter box for easy periodic replacement.

[0042] In some embodiments, the second filter bag is made of a deformable or flexible material. The second filter bag can be a disposable filter bag or a reusable filter bag. The filter bag material can be woven fabric, non-woven fabric, filter cotton, nylon mesh, biodegradable material, or composite filter membrane, etc. The material of the first filter bag is similar to that of the second filter bag.

[0043] In some embodiments of this application, such as Figure 3 , Figure 4As shown, the drainage assembly includes: a first drain outlet, located on the third receiving cavity, for discharging the liquid filtered by the second filter box out of the third receiving cavity.

[0044] In some embodiments, the first drain outlet is located at the bottom of the third receiving cavity; or, the first drain outlet is located on the side of the third receiving cavity.

[0045] In some embodiments, such as Figure 3 As shown, a second gap 2110413 is formed between the second filter box and the third receiving cavity. For example, in some embodiments, at least two support protrusions 200025 are provided on the bottom of the third receiving cavity and at least one of the bottoms of the second filter box, so that a second gap is formed between the bottom of the second filter box and the bottom of the third receiving cavity. The liquid filtered by the second filter box enters the second gap and is then discharged from the third receiving cavity through the first drain outlet. At the same time, the provision of support protrusions provides a stable pressure-bearing support for the second filter box, which can effectively disperse the concentrated stress caused by the accumulation of garbage or the impact of water flow during cleaning operation, and prevent the second filter box from undergoing structural deformation such as denting, bending or edge warping. Optionally, at least two support protrusions are provided on the bottom of the third receiving cavity, and the support protrusions abut against the bottom of the second filter box. Structurally, a hollow column is provided inside the support protrusion, and a hollow protrusion is provided on the second bottom shell 20001c of the base station body. The hollow column is correspondingly provided with the hollow protrusion, and a through hole is provided in the hollow protrusion. The connecting screw passes through the through hole and extends into the hollow column to achieve at least a partial fixed connection between the support protrusion and the second bottom shell. This arrangement further enhances the structural strength near the support protrusion and prevents the structure near the support protrusion from sinking or deforming under stress. In some embodiments, the second filter box overlaps the side of the third receiving cavity to form a second gap between the bottom of the second filter box and the bottom of the third receiving cavity.

[0046] In some embodiments, the bottom of the third receiving cavity includes at least one first guide portion 2110411, which slopes downward from its top towards the first drain outlet to guide liquid on the first guide portion to the first drain outlet. This prevents liquid from spreading disorderly at the bottom of the third receiving cavity or from accumulating water in corners, thereby preventing internal dampness from causing mold or component corrosion. Further, in some embodiments, each side of the third receiving cavity has at least one first guide portion 2110411, with adjacent first guide portions 2110411 smoothly transitioning together. Figure 3 As shown, a first guide portion and a second guide portion 2110412 are respectively provided on both sides of the first drain outlet at the bottom of the third receiving cavity. The first drain outlet is located at the lowest point of the inclined position of the first guide portion and the second guide portion.

[0047] In some embodiments of this application, such as Figure 3 , Figure 7As shown, the drainage assembly also includes a drainage component 2000265. The drainage component has a drainage channel, is disposed on the base station body, and at least a portion of the drainage component is located outside the third receiving cavity. One open end of the drainage component is connected to the first drain outlet, and the other open end serves as the third drain outlet 2000269 (or may be the final drain outlet), which is exposed to the external environment. The first nozzle, first filter box, second filter box, first drain outlet, and drainage component are sequentially fluidly connected to form a first clean water path.

[0048] To adapt to various drainage needs, the third drain outlet can be directly connected to the sewer, or the liquid discharged from the third drain outlet can be diverted to the sewer, lawn area, or swimming pool / pond via an output pipe. The output pipe can be made of corrugated PVC or rubber hose, which can effectively prevent corrosion and resist aging. The output pipe can be fixedly connected to the third drain outlet of the drainage component through threaded connection, snap-fit ​​connection, or sealing joint, ensuring reliable sealing and easy operation during the drainage process.

[0049] In some embodiments, the third drain outlet is exposed to the external environment from the side of the base station body. This configuration changes the drainage path from vertical to lateral, allowing users to directly connect the output pipe without raising the base station body or adjusting the installation angle, enabling quick connection and immediate discharge. This avoids slow drainage or backflow problems caused by bends obstructing the water flow, allowing the water to flow out naturally and smoothly under the guidance of the drainage component. In some embodiments, a leveling structure 200029 is provided at the lower end of the base station body to adjust the horizontal state of the base station body. In the initial position (when the base station is at its lowest height), the lowest point of the drainage component is higher than the lowest point of the leveling structure, meaning there is a certain distance between the drainage component and the ground, thus providing the user with a certain amount of operating space.

[0050] In some embodiments of this application, such as Figure 3 , Figure 7 As shown, the drainage assembly also includes a water receiving chamber 2000264, at least partially located below the third receiving cavity. The first drain outlet is connected to the sixth inlet of the water receiving chamber, and the drainage component is connected to the outlet of the water receiving chamber and communicates with the inside of the water receiving chamber. The first nozzle, the first filter box, the second filter box, the first drain outlet, the water receiving chamber, and the drainage component are sequentially fluidly connected to form a first clean water path.

[0051] In some embodiments, the first drain outlet extends into the sixth inlet, and the cross-sectional area of ​​the sixth inlet is greater than or equal to the cross-sectional area of ​​the first drain outlet. In this example, by adopting an embedded docking design between the first drain outlet and the sixth inlet of the water receiving chamber, and ensuring that the cross-sectional area of ​​the sixth inlet is greater than or equal to the cross-sectional area of ​​the first drain outlet, the problems of easy leakage, overflow, and poor drainage in existing base station water circuits are fundamentally solved. The design that the cross-sectional area of ​​the sixth inlet is greater than that of the first drain outlet provides more ample space for water flow. Even if a large amount of cleaning water instantly accumulates in the third receiving chamber during the cleaning process, the sixth inlet can quickly receive the entire flow, preventing backflow or splashing.

[0052] In some embodiments, such as Figure 4 As shown, the second bottom shell of the base station body includes at least one fifth guide section 20001c1. The fifth guide section slopes downward from its top towards the sixth inlet of the water receiving tank or an opening of the drainage component. The fifth guide section enables all water flowing to the surface of the second bottom shell to continue flowing in a predetermined inclined direction and converging into the water receiving tank or drainage component, avoiding water stagnation or dead zones. In addition, the inclined direction of the fifth guide section is basically consistent with the inclined direction of the first guide section and / or the second guide section, so that the upper and lower guide surfaces are perfectly connected in geometric direction, forming a continuous gravity guide path. This not only improves the drainage efficiency but also reduces turbulence and backflow of water at the bottom, ensuring a clear and smooth drainage path.

[0053] In some embodiments, such as Figure 3 As shown, a sixth guide section 20001c2 is provided on the side of the water receiving chamber near the fifth guide section. The tilt angle of the sixth guide section is greater than that of the fifth guide section. The sixth guide section can guide the water flow into the water receiving chamber quickly and smoothly, and then out of the base station from the drain component, avoiding the accumulation of liquid in the corners of the water receiving chamber.

[0054] In some embodiments, such as Figure 7 As shown, the water receiving tank is an independent structure connected to the bottom of the second bottom shell and / or the third receiving cavity. A guide step 211044 is provided at the bottom of the third receiving cavity. The guide step serves both as a water flow guide and a structural fixation function. It can guide the liquid entering the third receiving cavity to converge towards the target area and also serve as a fixing platform to facilitate the connection and positioning of the water receiving tank below it. In some embodiments, the guide step is provided at the inclined end of the first guide portion and / or the second guide portion near the water receiving tank.

[0055] In some embodiments, such as Figure 3 , Figure 4 , Figure 7As shown, the first drain outlet is located at the bottom of the third receiving chamber. At least a portion of the sixth inlet is located at the top of the water receiving tank, and the first drain outlet is located directly above at least a portion of the sixth inlet. This arrangement allows the liquid collected in the third receiving chamber to flow vertically into the water receiving tank under the influence of gravity, forming a continuous and smooth downward drainage path.

[0056] In some embodiments, a guide portion is provided around the periphery of the first drain outlet. The guide portion is arranged in a funnel shape, a cone shape, or an inclined shape, so that the liquid can be guided to the sixth inlet when it flows out of the first drain outlet.

[0057] In some embodiments, the first drain outlet is located at the lowest point of the bottom of the third receiving cavity. This arrangement forms a water flow convergence point for the entire cavity, ensuring that no stagnation zones or dead zones form within the third receiving cavity. Regardless of where the liquid flows out from the second filter box, it will eventually converge at the lowest point of the bottom of the third receiving cavity and drain smoothly, preventing the liquid from stagnating on the surface of the third receiving cavity and causing poor drainage.

[0058] In other embodiments, the first drain outlet is located on the side of the third receiving cavity. For example, in some embodiments, the first drain outlet is located on one side of the third receiving cavity, and to facilitate the smooth discharge of liquid from the third receiving cavity, the first drain outlet is located at the lowest point of the bottom of the third receiving cavity, which is located at the junction of the side and the bottom of the third receiving cavity. At least a portion of the sixth inlet is located at this junction and communicates with the first drain outlet.

[0059] In some embodiments of this application, such as Figure 7 As shown, the drainage assembly also includes at least one second driving component 2000266, disposed on the first clean water path and located downstream of the second filter box, for driving the liquid filtered by the second filter box to drain from the base station body. For example, the second driving component is a second water pump. By setting the second driving component downstream of the first clean water path, the drainage process is upgraded from relying solely on gravity discharge to a combined gravity and active driving drainage, thereby improving the overall drainage efficiency.

[0060] In some embodiments, the second water pump includes: a second motor; and a second impeller, wherein the second motor drives the second impeller to rotate, and the second impeller is located at least on the first cleaning water path and downstream of the second filter box, and between the first drain outlet and the third drain outlet. In some embodiments, the second impeller is located downstream of the first drain outlet and upstream of the third drain outlet.

[0061] In some embodiments, the second impeller is located within the water receiving chamber. This arrangement allows the liquid to be driven immediately upon entering the water receiving chamber, reducing the residence time of the liquid within the chamber. In some embodiments, the draining component is intersecting with the water receiving chamber, meaning at least a portion of the draining component overlaps structurally or spatially with the water receiving chamber, thereby achieving a compact integration of the draining drive structure. In other embodiments, the draining component and the water receiving chamber may also be arranged in parallel.

[0062] In some embodiments, the second motor of the second water pump may be located in the seventh receiving cavity, and the output shaft of the second motor extends through the seventh receiving cavity into the water receiving chamber and connects to the second impeller. Alternatively, the second water pump may not be located in the seventh receiving cavity.

[0063] In some embodiments, the second pump is a centrifugal pump. Alternatively, the second pump can also be other types of pumps, such as axial flow pumps, mixed flow pumps, positive displacement pumps, etc. The centrifugal pump includes a second motor 20002661, an impeller housing 20002662, and a centrifugal impeller (not shown in the figure). The centrifugal impeller is disposed inside the impeller housing, which has an inlet 20002662a and an outlet 20002662b. The inlet is connected to a water receiving chamber, and the outlet is connected to a drainage channel. The output shaft of the second motor extends into the impeller housing and is connected to the centrifugal impeller.

[0064] Liquid in the third receiving chamber enters the water receiving tank through the first drain outlet. Liquid in the water receiving tank then enters the centrifugal impeller through the inlet. The second motor drives the centrifugal impeller to rotate, discharging the liquid from the outlet to the drainage channel, and finally out of the base station. In this embodiment, because the second water pump is a centrifugal pump, it can quickly discharge the liquid in the third receiving chamber out of the base station with a large flow rate, preventing liquid accumulation in the third receiving chamber and the water receiving tank.

[0065] Furthermore, in some embodiments, such as Figure 25-27 As shown, the water receiving chamber includes a first sub-water receiving chamber 20002641 and a second sub-water receiving chamber 20002642. The first and second sub-water receiving chambers are connected and communicate with each other. The drainage component is located on the second sub-water receiving chamber. The base station also includes a bracket 200028 for installing a centrifugal water pump. The bracket is located on the second water receiving chamber. When the centrifugal water pump is installed on the bracket, the water inlet of the impeller housing is communicated with the inside of the second sub-water receiving chamber, and the water outlet of the impeller housing is in fluid communication with the drainage channel.

[0066] For example, in some embodiments, the bottom of the seventh receiving cavity has an opening or notch through which the upper part of the support is located within the seventh receiving cavity, and the lower part of the support extends into the second sub-water receiving chamber, so that both the inlet and outlet of the impeller housing are connected to the second water receiving chamber. For example, an output water pipe can be provided on the outlet of the impeller housing, extending into the drainage channel, so that the outlet of the impeller housing and the drainage channel are connected. Alternatively, the outlet of the impeller housing is located in the second sub-water receiving chamber and is directly connected to the drainage channel.

[0067] In some embodiments of this application, such as Figure 8 , Figure 9 As shown, the second cleaning component also includes a liquid inlet mechanism, at least for conveying liquid from the water supply component to the first nozzle. The liquid inlet mechanism, the first nozzle, the first filter box, the second filter component, and the liquid draining component are sequentially fluidly connected to form a first cleaning water path. The water supply component can be any structure capable of providing a water source, such as a faucet, pool, or tank. The water supply component is not part of the base station structure.

[0068] In some embodiments, such as Figure 8 As shown, the liquid inlet mechanism includes at least: a first liquid inlet component 21801, one end of which is connected to the first nozzle; and a second liquid inlet component 21791, one end of which is connected to the first liquid inlet component, and the other end of which is in fluid communication with the water supply component.

[0069] In some embodiments, the second liquid inlet component and the water supply component can be fixed by various detachable connection methods such as threaded connection (with waterproof seal), quick-connect connector (quick-connect male and quick-connect female), snap-fit ​​connection, pagoda connector + hose clamp connection, magnetic connection, and flange connection.

[0070] In some embodiments, the first liquid inlet component and the second liquid inlet component are rotatably and sealingly connected to switch the first nozzle between a first position (i.e., the extended position) and a second position (i.e., the retracted position). In the first position, the first nozzle extends into the first body; in the second position, the first nozzle retracts from the first body.

[0071] In some embodiments, the second cleaning component further includes at least one driving component for driving the first liquid inlet component to rotate, thereby switching the first nozzle between a first position and a second position. The driving component may be disposed within the base station body or the support base 2171. The driving component includes, but is not limited to, motor drive, hydraulic drive, pneumatic drive, magnetic drive, mechanical drive, etc. For example, in some embodiments, such as... Figure 8As shown, the drive assembly includes a third motor, which is disposed within the support base. The third motor is rotatably connected to the first liquid inlet component, and drives the first liquid inlet component to rotate, thereby switching the first nozzle 2173 between a first position and a second position. For example, the third motor drives a transmission assembly to rotate the first liquid inlet component, thereby switching the first nozzle between the first position and the second position. Further, in some embodiments, when the third motor 2174 is not activated, the user can manually drive the first liquid inlet component to move the first nozzle, thereby switching the first nozzle between the first position and the second position.

[0072] In some embodiments, at least a portion of the second liquid inlet component is disposed within the base station body; and at least a portion is exposed outside the base station body or the external environment, for fluid communication with the water supply component. At least a portion of the first liquid inlet component is exposed outside the base station body for connection to the first nozzle; at least a portion of the first liquid inlet component extends into the base station body and connects to the second liquid inlet component.

[0073] In some embodiments, such as Figure 8 As shown, the first liquid inlet component includes at least a first delivery pipe 21802 (also referred to as a nozzle support arm or support arm) and a first connecting pipe 21803. The two ends of the first delivery pipe are connected to the first nozzle and the first connecting pipe, respectively, and both the first delivery pipe and the first nozzle are located above the base station body. A portion of the first connecting pipe extends into the base station body and connects to the second liquid inlet component. A waterproof sealing ring is provided between the first connecting pipe and the first delivery pipe to achieve a sealed connection, prevent liquid leakage, and maintain the sealing stability of the water system.

[0074] In some embodiments, such as Figure 8 As shown, the second liquid inlet component includes at least a second delivery pipe 21793 and a second connecting pipe 21796. One end of the second connecting pipe is connected to the first connecting pipe. One end of the second delivery pipe is connected to the second connecting pipe, and the other end extends out of the base station body or is exposed to the external environment for fluid communication with the water supply component.

[0075] When the second delivery pipe is connected to the second connecting pipe, the second delivery pipe can deform to make an interference fit with the barb 217961 on the outside of the second connecting pipe, ensuring a sealing effect at the interface. Furthermore, a fastener can be added to the outside of the water inlet pipe at the connection between the water inlet pipe and the second connecting pipe. The fastener can better ensure the sealing effect at the interface, prevent liquid leakage, and maintain the sealing stability of the water system.

[0076] In some embodiments of this application, such as Figure 4 , Figure 20As shown, the base station body also includes a sixth receiving cavity 2020, at least partially located above at least a portion of the third receiving cavity. At least a portion of the first liquid inlet component extends into the sixth receiving cavity and is connected to at least a portion of the second liquid inlet component.

[0077] In some embodiments of this application, such as Figure 8 As shown, the base station body also includes a seventh receiving cavity 2057, at least partially located below at least a portion of the sixth receiving cavity and spaced apart from the third receiving cavity. At least a portion of the second liquid inlet component is located within the sixth receiving cavity and connected to the first liquid inlet component. At least a portion of the second liquid inlet component is located within the seventh receiving cavity, and at least a portion of the second liquid inlet component extends out of the seventh receiving cavity from the base station body or is exposed to the external environment. Horizontally, the seventh receiving cavity and the third receiving cavity are adjacent to or close to each other.

[0078] Specifically, a portion of the first connecting pipe extends into the sixth receiving cavity, and at least a portion of the second connecting pipe is located within the sixth receiving cavity. The first and second connecting pipes are sealed together. A waterproof sealing ring is provided between the second and first connecting pipes to ensure a sealed connection, prevent liquid leakage, and maintain the sealing stability of the water system. At least a portion of the second delivery pipe is located within the seventh receiving cavity. For example, the second connecting pipe may be located within the sixth receiving cavity, with one end extending into the sixth receiving cavity and connecting to the second connecting pipe, while the other end extends out of the seventh receiving cavity from the base station body or is exposed to the external environment, facilitating connection between the second delivery pipe and the water supply component.

[0079] In some embodiments, the second delivery pipe is an explosion-proof water pipe, which can prevent the water pipe from bursting under excessive water pressure, and can also prevent damage caused by twisting and bending, resulting in a long service life. The interface of the explosion-proof water pipe is equipped with a pure copper or brass connector with an anti-slip tooth design, which can tightly engage with faucets, etc., and is not easy to fall off due to water pressure or pulling, and the interface is not prone to leakage. The connector can also be equipped with a quick coupling, which allows users to quickly install or remove the water pipe, while also preventing liquid leakage.

[0080] In some embodiments, the second liquid inlet component further includes a third delivery pipe, one end of which is in fluid communication with the water supply component, and the other end of which is connected to the second delivery pipe. The third delivery pipe is located outside the base station body or exposed to the external environment.

[0081] In some embodiments of this application, such as Figure 8 As shown, the liquid inlet mechanism also includes at least one one-way valve 21792, disposed on at least one of the first liquid inlet component and the second liquid inlet component; or disposed between the first liquid inlet component and the second liquid inlet component. The one-way valve only allows liquid from the water supply component to flow unidirectionally from the second liquid inlet component to the first liquid inlet component and the first nozzle.

[0082] The one-way valve is at least one of a solenoid valve, a baffle valve, a ball valve, or a butterfly valve. Because the liquid inlet mechanism includes a one-way valve, the faucet can be in a normally open state when the first nozzle is connected to an indoor or outdoor faucet in the user's home. The opening or closing of the one-way valve is controlled by the base station's control module to control whether the first nozzle sprays or stops spraying cleaning liquid.

[0083] When a check valve is positioned between the first and second inlet components, for example, on valve mounting base 21795 between the first and second inlet components, the solenoid valve may deviate from the central axis of the first inlet component when the first inlet component rotates, causing concentric misalignment and resulting in liquid leakage at the connection. Furthermore, if the check valve is misaligned during installation, the concentric misalignment problem will be more severe when the first inlet component rotates.

[0084] Therefore, in the embodiments of this application, such as Figure 8 As shown, the base station body includes a seventh receiving cavity, which is separated from the third receiving cavity. A one-way valve is disposed on a second liquid inlet component, and at least a portion of the second liquid inlet component and the one-way valve are both disposed within the seventh receiving cavity. At least a portion of the second liquid inlet component extends out of the seventh receiving cavity to be exposed to the external environment or the base station body.

[0085] In this example, the check valve is mounted on the second inlet component, which remains essentially stationary, and there is no issue of concentric misalignment between the check valve and the second inlet component.

[0086] In embodiments of this application, the liquid inlet mechanism further includes at least one first driving member, disposed on the first liquid inlet component and / or the second liquid inlet component; or disposed between the first liquid inlet component and the second liquid inlet component; or disposed between the water supply component and the second liquid inlet component. The first driving member is used to drive the liquid from the water supply component to flow to the first nozzle. For example, the first driving member is a first water pump.

[0087] In some embodiments, the first driving element is located outside the base station body; or, the first driving element is located inside the base station body.

[0088] For example, the first water pump is located between the water supply component and the second liquid inlet component, or the first water pump is located on the second liquid inlet component and outside the base station; or the first water pump is located on the second liquid inlet component and inside the base station body, for example, the first water pump is located in the seventh accommodating cavity; or the first water pump is located in the sixth accommodating cavity.

[0089] At least a portion of the drain component is located below at least a portion of the seventh receiving cavity. Both the drain component and the second inlet component are exposed to the environment on the same side of the base station. With this configuration, the base station structure is more compact, space utilization is higher, and users do not need to detour or frequently change positions; all water supply and drainage operations can be completed from one side of the base station, greatly simplifying the equipment usage process, especially in narrow or wall-mounted environments, where all connection operations can be easily completed. In some embodiments, the first water pump includes a first motor, which is located within the seventh receiving cavity. In this example, both the second and first motors are located within the seventh receiving cavity, which helps optimize space utilization and maintain a compact layout.

[0090] In the embodiments of this application, such as Figure 18 , Figure 24 The pool robot also includes at least one fourth inlet 1016, located on the first body, for allowing cleaning liquid from the first nozzle to enter the interior of the first body to perform self-cleaning on the first filter box.

[0091] In some embodiments, the first body includes a first receiving cavity 10013 disposed on the first body. At least a portion of the first filter cartridge is disposed within the first receiving cavity. A fourth inlet communicates with the first receiving cavity. A first nozzle extends through the fourth inlet into the first receiving cavity for spraying liquid into the first filter cartridge.

[0092] In some embodiments, the first nozzle extends into the first filter box of the pool robot through the fourth inlet and sprays liquid into the first filter box. In other embodiments, the first nozzle extends into the first body through the fourth inlet but is located outside the first filter box (e.g., the first gap 10582 between the first receiving cavity and the outside of the first filter box), spraying liquid from the outside of the first filter box into the first filter box. The first nozzle may extend partially or completely into the first gap. Alternatively, in other embodiments, the first nozzle may not extend into the first body; the first nozzle remains outside the pool robot, and the liquid sprayed by the first nozzle is sprayed into the first filter box through the fourth inlet.

[0093] In some embodiments, the fourth inlet is in communication with the inner cavity of the first filter box. The first nozzle extends into the first filter box through the fourth inlet to spray liquid into the first filter box.

[0094] In some embodiments, the first body further includes a pick-and-place port 1017, at least partially disposed on the top of the first body, communicating with the first receiving cavity, for inserting or removing the first filter cartridge into or from the first receiving cavity. The first filter cartridge includes an eleventh opening 10532, at least partially disposed on the top of the first filter cartridge. The eleventh opening communicates with the pick-and-place port. The pick-and-place port serves as a fourth inlet, through which the first nozzle extends into the first filter cartridge.

[0095] In other embodiments, the first body further includes a second inlet 1032, located on the side of the first body, for at least allowing debris on the liquid surface to enter the first filter box. The first filter box includes at least one second inlet 10511b, located on the side of the first filter box. The second inlet and the second inlet are adjacent to and communicate with each other. The second inlet serves as a fourth inlet, through which the first nozzle extends into the first filter box.

[0096] In some embodiments, a first nozzle extends into a first filter cartridge, with at least a portion of the nozzle facing the third opening and / or the side of the first filter cartridge.

[0097] In some embodiments, such as Figure 12 As shown, the first nozzle includes at least one first spray nozzle 217321, which is used at least to spray liquid onto the side of the first filter box; and / or at least one second spray nozzle 217322, which is used at least to spray liquid onto the bottom of the first filter box.

[0098] By setting multiple water outlets with different directions on the first nozzle, the liquid is sprayed in different directions from the different nozzles, so that the liquid is sprayed onto different side walls and bottom walls inside the first filter box, thus ensuring the cleaning effect of the first filter box.

[0099] In the embodiments of this application, such as Figure 22 As shown, the first body also includes a second baffle 10511d, which is rotatably disposed on the side of the first body to open or close the second water inlet. After the second baffle opens the second water inlet, the first nozzle extends into or exits the first filter box through the second water inlet.

[0100] When the second shielding cover 21811 is provided on the first liquid inlet component, when the second baffle opens the second water inlet, the second shielding cover is approximately located below the second baffle, that is, the pivot of the second baffle is approximately located at the upper edge of the second water inlet. The second shielding cover can prevent part of the liquid sprayed by the first nozzle from flowing out of the pool robot from the second water inlet.

[0101] In the embodiments of this application, such as Figure 22 As shown, the first body also includes a seventh opening 1033, at least partially disposed on the bottom of the first body, communicating with the first receiving cavity. The first filter box also includes a first bottom cover, movably disposed on the third opening, for closing or opening the third opening. The seventh opening is at least used to expose the first bottom cover to the bottom of the first body or to the external environment.

[0102] Additionally, the seventh opening also allows the first bottom cover to rotate at the seventh opening to open or close the third opening. For example, the first bottom cover can rotate through the seventh opening to the outside of the bottom of the first body to open the third opening. When the first bottom cover closes the third opening, the first bottom cover serves as part of the bottom of the pool robot, and the first bottom cover is roughly flush with the bottom of the first body, together forming the bottom of the pool robot.

[0103] In the embodiments of this application, such as Figure 23 As shown, a first gap is formed between the first receiving cavity and the first filter box. The first gap communicates with the outside through at least a seventh opening. The first nozzle, the first filter box and / or the first gap, the second filter box, and the drainage assembly are sequentially fluidly connected to form a first cleaning water path.

[0104] Specifically, after the liquid sprayed from the first nozzle enters the first receiving cavity, it can form two water paths: a main water path exiting from the first filter box and its third opening, and an auxiliary water path exiting from the first gap and its seventh opening. If the first gap is not sealed, both the main and auxiliary water paths exist. If the first gap is sealed, the liquid mainly exits from the third opening of the first filter box; or, if the first gap is very small, the auxiliary water path can be ignored. In both cases, only the main water path exists.

[0105] In the embodiments of this application, such as Figure 8 , Figure 9 , Figure 11 , Figure 16 As shown, the first nozzle is rotatably connected to the first liquid inlet component.

[0106] In some embodiments, the first nozzle includes at least one first spray nozzle, from which liquid is sprayed to drive the first nozzle to rotate relative to the first liquid inlet component. Specifically, the first nozzle may be a spinning nozzle, which does not require an external motor drive. During the spraying process, high-pressure liquid enters the first liquid inlet component and is sprayed out from the first spray nozzle. The liquid sprayed from the first spray nozzle exerts a force on the first nozzle to drive it to rotate, causing the first spray nozzle to spray liquid in different directions into the first filter box, thereby enabling thorough cleaning of the first filter box. Alternatively, in other embodiments, the first nozzle may also be driven by a motor to rotate relative to the first liquid inlet component.

[0107] In some embodiments, such as Figure 16As shown, to allow the first nozzle to extend into the first filter box and clean it, corresponding to the aforementioned fourth inlet, the pool robot also includes at least one twelfth opening 10536. The twelfth opening is located on the first filter box, and the fourth inlet and the twelfth opening are adjacent or close to each other and communicate with each other. The first nozzle extends into the first filter box or exits the first body through the fourth inlet and the twelfth opening. In some embodiments, the twelfth opening is located at the top, side, or near the top of the first filter box. For example, when the second inlet is used as the fourth inlet, the second inlet is correspondingly used as the twelfth opening; or, when the pick-up / drop-off port is used as the fourth inlet, the eleventh opening is correspondingly used as the twelfth opening.

[0108] Since the first nozzle extends into the first body of the pool robot from the fourth inlet, and the first nozzle is within the height range of the fourth inlet, when the first nozzle rotates to spray liquid, some liquid will flow out of the pool robot from the fourth inlet.

[0109] Therefore, in some embodiments of this application, such as Figures 11 to 18 As shown, the second cleaning assembly also includes a shielding assembly 2181, which is fixed relative to the first nozzle. When the first nozzle extends into the first filter box, the shielding assembly is used to shield at least a portion of the fourth inlet and / or the twelfth opening to prevent the liquid sprayed by the first nozzle from flowing out of the first body from the fourth inlet; when the first nozzle exits the first body, the shielding assembly leaves the fourth inlet and the twelfth opening, allowing the fourth inlet and the twelfth opening to be exposed again, thereby forming a dynamic seal or semi-seal structure under the condition of spraying cleaning liquid, effectively suppressing the overflow of cleaning liquid from the fourth inlet.

[0110] When the second inlet is used as the twelfth opening, the first nozzle can extend into the first filter box through the second inlet and the second inlet in sequence. The shielding component is used to shield at least a portion of the second inlet and / or the second inlet to prevent the liquid sprayed by the first nozzle from flowing out of the first body from the fourth inlet.

[0111] In some embodiments of this application, such as Figure 11 As shown, the shielding assembly includes: a second shielding cover for shielding at least a portion of the fourth inlet when the first nozzle is inserted into the first filter box; and a flexible water-blocking member 21812, at least partially surrounding the outer periphery of the second shielding cover, for preventing liquid ejected by the first nozzle from flowing out of the first body through the sixth gap 2181244 between the second shielding cover and the fourth inlet.

[0112] By setting a shielding component on the first liquid inlet component that moves synchronously with the first liquid inlet component, the leakage of high-pressure jet liquid through the sixth gap is effectively suppressed without affecting the insertion or withdrawal of the first nozzle, thus preventing the cleaning liquid from splashing to the outside of the pool robot, improving the water utilization rate of internal cleaning operations and the overall sealing reliability of the machine.

[0113] In some embodiments, such as Figure 13 , Figure 14 As shown, the flexible water-blocking component includes a first flexible component 218121, which is at least partially wrapped around the outer periphery of the second shielding cover for shielding at least a portion of the sixth gap.

[0114] Furthermore, in some embodiments, such as Figure 15 , Figure 16 As shown, the first flexible member includes: a first open end 2181211, at least partially surrounding the outer periphery of the second shielding cover; a second open end 2181212; and a buffer cavity 2181213 extending from the first open end to the second open end. When the first nozzle is inserted into the first filter box, at least a portion of the buffer cavity is located within the twelfth opening, and the second open end is close to, adjacent to, or extends into the inner cavity of the first filter box, for allowing liquid in the buffer cavity to flow into the first filter box.

[0115] By forming a buffer cavity with a flow guiding function on the first flexible component, it not only serves to block water but also guides the sprayed liquid back into the filter box, achieving a composite effect of "blocking without clogging and leaking without leakage," thus avoiding turbulence or liquid backflow at the inlet and further improving the reliability of the seal.

[0116] In some embodiments of this application, such as Figure 13 , Figure 14 , Figure 17 As shown, the flexible water-blocking component also includes At least one second flexible member 218122 is at least partially wrapped around the second open end of the first flexible member and extends outward. When the first nozzle is inserted into the first filter box, a third gap 2181241 exists between the first flexible member and the twelfth opening. The second flexible member is located inside the first filter box to cover at least a portion of the third gap.

[0117] In some embodiments of this application, such as Figure 17 As shown, when the first nozzle extends into the first filter box, a fourth gap 2181242 is formed between the second flexible member and the inner wall of the first filter box.

[0118] By providing a second flexible member inside the first flexible member, the third gap is blocked a second time, further improving the overall sealing coverage area at the entrance of the first nozzle into the first filter box. A fourth gap is provided between the second flexible member and the inner wall of the first filter box to prevent the second flexible member from contacting the inner wall of the first filter box. When the first nozzle moves, the second flexible member is stuck at the twelfth opening and cannot smoothly exit from the twelfth opening, thus improving the smoothness of the first nozzle's movement.

[0119] In some embodiments, such as Figure 13 The first flexible member also includes an annular protrusion 2181214, which is disposed on the end of the first opening. An annular groove 2181215 is provided on the inner wall of the annular protrusion. The first flexible member is sleeved on the outer periphery of the second cover through the annular groove.

[0120] In some embodiments, such as Figure 13 , Figure 14 , Figure 18 As shown, the flexible water-blocking component also includes at least one third flexible component 218123, which is at least partially wrapped around the outer wall of the first flexible component and extends outward. The third flexible component is located between the first opening end and the second opening end. When the first nozzle is inserted into the first filter box, a fifth gap 2181243 exists between the top of the first flexible component and the top of the fourth inlet. The third flexible component serves at least to prevent liquid entering the fifth gap from flowing out toward the fourth inlet.

[0121] By using the third flexible component to directionally seal the fifth gap, the liquid entering this area is preferentially guided back into the first filter box, preventing it from overflowing along the top of the inlet, and further enhancing the leak-proof capability of the first nozzle extending into the inlet area of ​​the first filter box.

[0122] In some embodiments, such as Figure 18 As shown, the bottom of the fourth inlet has an upwardly protruding first rib 10161. When the first nozzle extends into the first filter box, a seventh gap 2181245 is formed between the bottom of the third flexible member and the bottom of the fourth inlet. The third flexible member is located between the first rib and the second flexible member. The first rib is at least used to prevent liquid in the seventh gap from flowing out of the fourth inlet.

[0123] In this example, the first rib allows the liquid in the seventh gap to flow from the twelfth opening into the first filter box. The seventh gap is formed between the bottom of the third flexible member and the bottom of the fourth inlet primarily to prevent the third flexible member from obstructing or affecting the rotation of the first nozzle. If the bottom of the third flexible member were to abut against the bottom of the fourth inlet, the third flexible member could easily become stuck at the bottom of the fourth inlet, causing the first nozzle to rotate unevenly.

[0124] In some embodiments of this application, the first nozzle is retractably or vertically mounted on the first liquid inlet component. In the height direction of the pool robot, the first nozzle has an initial position and a working position. In the initial position, the first nozzle can extend into or out of the first body through the fourth inlet, and the first nozzle is within the height range of the fourth inlet; in the working position, in the height direction of the pool robot, the first nozzle is below the lower edge of the fourth inlet. The first nozzle switches between the working position and the initial position through retracting or vertical movement.

[0125] In this example, since the first nozzle is below the lower edge of the fourth inlet in the working position, the range of liquid sprayed by the first nozzle is approximately below the fourth inlet, and the sprayed liquid will not flow out of the pool robot from the fourth inlet. By controlling the height of the first nozzle, it is positioned within the inlet height range when entering or exiting the main body, and then lowered to below the fourth inlet during cleaning operations, preventing liquid from overflowing beyond the inlet at the source. In this case, no shielding component is needed on the first liquid inlet component. In this embodiment, when the first nozzle switches between the initial position and the working position, it can use a linear extension and retraction along the axial direction of the first liquid inlet component, or it can use a lifting and lowering motion along a vertical guide rail structure, or it can use a mechanical linkage, eccentric wheel, or cam mechanism for height switching. The first nozzle is driven by a motor, lead screw, or electric push rod to achieve lifting and lowering.

[0126] In some embodiments of this application, such as Figure 2 , Figure 3 , Figure 19 As shown, the base station body also includes a dwelling area 21823, at least partially disposed on the top of the base station body, the dwelling area being used at least for the pool robot to dock. A fourth opening is located within the dwelling area. The base station also includes a drainage mechanism, including at least one first drainage port 21831 disposed on the dwelling area, the first drainage port being in fluid communication with a third receiving cavity, for draining at least a portion of the liquid in the dwelling area into the third receiving cavity.

[0127] In some embodiments, a dwelling area is provided on the top of the base station body (such as on the second upper shell 20001a). When the pool robot docks on the top of the base station, its body surface, bottom and spray residue can naturally collect in the dwelling area under the action of gravity, and be quickly introduced into the third receiving cavity through the first drainage port, so as to avoid the liquid from stagnating on the top of the base station or overflowing outward.

[0128] Furthermore, in some embodiments Figure 20 In the middle, the first drainage port is densely arranged, or a filter screen is installed on the first drainage port, so as to effectively prevent debris and dust from clogging it.

[0129] In some embodiments, as shown, the drainage mechanism further includes: at least one second transition cavity 21832 communicating with the first drainage port; and at least one second drainage port 21833 communicating the second transition cavity and the third receiving cavity. The first drainage port, the second transition cavity, the second drainage port, and the third receiving cavity are sequentially fluidly connected to form a drainage water path.

[0130] By setting up a second transition chamber, the liquid from the residence area first enters the buffer space and then flows into the third receiving chamber in an orderly manner, which can reduce the impact of instantaneous water flow, avoid water splashing, and improve the overall controllability of the flow.

[0131] In some embodiments, such as Figure 20 As shown, the bottom of the second transition cavity includes at least one first guide surface 218321. The first guide surface slopes downward from its upper end to its lower end, and the lower end of the first guide surface extends approximately to the second drain port. By using the inclined first guide surface, gravity can be used to guide the liquid to quickly concentrate to the second drain port, reducing liquid stagnation at the bottom of the second transition cavity and improving drainage efficiency.

[0132] In some embodiments, such as Figure 20 As shown, the base station body includes a sixth receiving cavity, at least partially located above and spaced apart from the third receiving cavity. The sixth receiving cavity includes at least one second transition cavity, and a second drainage port is located at the bottom of the sixth receiving cavity. By arranging the second transition cavity within the sixth receiving cavity, a three-dimensional arrangement of the drainage structure is achieved, allowing the water path to connect naturally in space with the lower second filter box and drainage assembly, thus improving the overall compactness of the base station.

[0133] In some embodiments, such as Figure 20 , Figure 21 As shown, the base station body also includes a mounting plate 200013, which is disposed in the inner cavity of the base station body. Along the height direction of the base station body, the mounting plate divides the inner cavity of the base station body into at least a sixth receiving cavity and a third receiving cavity, with at least a portion of the sixth receiving cavity located above the third receiving cavity. The mounting plate 200013 is provided with a partition 21836, which is used to separate electrical components from water flow on the mounting plate, keeping the electrical component area dry and preventing short circuits or component damage caused by splashing or accumulating water during cleaning. Simultaneously, the first guide surface and / or the second drain port on the mounting plate allow liquid flowing down from the first drain port of the second upper shell to quickly flow to the third receiving cavity, preventing liquid accumulation or stagnation on the mounting plate and achieving smooth flow from the second upper shell to the second filter box.

[0134] In some embodiments of this application, such as Figure 2 , Figure 3 , Figure 19As shown, the top of the base station body includes at least: a resting part 21821, the upper surface of which is for the pool robot to rest; and a mounting part 21822, at least partially disposed around the edge of the resting part. The mounting part and the resting part together form a resting area. At least a portion of at least one first drainage port is disposed on the resting part; and / or at least a portion of at least one first drainage port is disposed on the mounting part, such that the first drainage port is located near the edge of the resting surface 200018.

[0135] The upper surface of the mounting part may be flush with the upper surface of the dwelling part, or the upper surface of the mounting part may be higher than the upper surface of the dwelling part, or the upper surface of the mounting part may be lower than the upper surface of the dwelling part.

[0136] In some embodiments, at least a portion of the mounting portion protrudes upwards and is disposed outside the edge of the dwell portion. At least a portion of at least one first drainage port is disposed on the inner sidewall of the mounting portion. For example, in some embodiments, the mounting portion protrudes upwards and surrounds the outer periphery of the dwell portion, with the mounting portion and the dwell portion together forming a recessed dwell area. The enclosing structure of the dwell portion and the mounting portion can form a partially recessed dwell area, allowing the liquid to naturally flow towards the edge and reducing the risk of spillage.

[0137] In some embodiments, such as Figure 3 , Figure 19 , Figure 20 As shown, the dwell section includes at least a first segment 2000181 and a second segment 2000182, with one end of the second segment fixedly connected to the first segment. The mounting section includes at least a second seat 218222, which is located at the edge of the other end of the second segment. At least a portion of at least one first drain port is located on the second seat. The second segment slopes generally downward from the first segment toward the second seat to form a second guide surface 21834.

[0138] In some embodiments, the dwell portion includes at least a third segment 2000183, one end of which is fixedly connected to a first segment, and the first segment is located between the third and second segments. The mounting portion also includes at least one third seat 218223, which is disposed at the edge of the other end of the third segment. At least a portion of at least one first drain port is disposed on the third seat. The third segment slopes generally downward from the first segment toward the third seat to form a third guide surface 21835. In some embodiments, the middle portion of the third seat does not have a first drain port, which can prevent liquid from flowing through the first drain port onto the fourth motor 70042 of the first closing mechanism 7004 on the mounting plate, thus avoiding any impact on the motor.

[0139] Furthermore, in some embodiments, the tilt angle of the third segment is greater than that of the second segment, allowing some of the liquid on the pool robot to be quickly discharged from the first drain port 105 at its bottom and then rapidly flow to the first drainage port on the third seat. Simultaneously, when the pool robot is placed on the resting surface, the larger tilt angle of the third segment provides sufficient accommodating space for the rear end of the pool robot.

[0140] In some embodiments, the mounting portion further includes at least one first seat 218221, at least partially disposed at the edge of the first segment. At least a first drainage port is at least partially disposed on the first seat.

[0141] By using multiple resting surfaces with different inclination angles and corresponding mounting bases with first drainage ports, residual liquid in different areas of the pool robot is diverted to the corresponding mounting bases, improving drainage efficiency and optimizing spatial adaptability when docking.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] 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.

[0149] The first body of the pool robot is provided with at least one first water outlet 1041. At least part of the first water outlet is located on the top of the first 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] 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.

[0154] 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.

[0155] 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.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] 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.

Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
