[0006] This invention belongs to the technical field of swimming pool cleaning equipment, and particularly relates to a base station. Background Technology

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

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

[0009] This application aims to solve the above-mentioned problems and discloses a base station that can automatically filter the garbage inside the base station and discharge the liquid to the outside of the base station in a timely manner. While reducing the space occupied by garbage inside the base station, it avoids secondary pollution through solid-liquid separation and prevents the garbage inside the base station from smelling bad. At the same time, it also discloses a nozzle driving device that can drive the first nozzle to automatically enter the pool robot and rinse the first filter box, so that the cleaning can be carried out without manual intervention and can accurately target the cleaning area, ultimately achieving stable automatic cleaning of the first filter box and improving the overall cleaning efficiency and ease of use.

[0010] This application discloses a base station for cleaning a first filter box of a swimming pool robot and receiving waste from the first filter box. The base station includes a base station body; a second filter box, at least partially disposed on the base station body, for receiving waste from the first filter box of the swimming pool robot; a second cleaning component disposed on the base station body; the second cleaning component includes at least one first nozzle for spraying liquid onto the first filter box to clean it; at least one second liquid inlet component fluidly connected to the first nozzle and fluidly connected to a water supply component; and a drive component for driving the first nozzle to move, such that the first nozzle switches between at least a first position and a second position. When the first nozzle moves from the second position to the first position, the first nozzle extends from outside the swimming pool robot into the swimming pool robot to spray liquid onto the first filter box, and the waste in the first filter box is received by the second filter box, thereby achieving automatic cleaning of the first filter box without manual intervention from the user. When the first nozzle moves from the first position to the second position, the first nozzle retracts outside the swimming pool robot.

[0011] This application also discloses a cleaning system, including a base station and a pool robot; wherein the base station is the base station described above.

[0012] This application sets up a second filter box to receive the waste in the first filter box, so as to automatically transfer the waste in the first filter box to the second filter box; in addition, the waste received by the second filter box is further filtered, and the filtered liquid is discharged from the base station in a timely manner, which can prevent the waste from smelling bad in the second filter box.

[0013] This application provides a nozzle drive device that can actively drive the first nozzle to move, so that the first nozzle can automatically move from the storage position to the working position and back to the storage position according to the control signal during the cleaning process. This eliminates the need for the user to manually connect or align the nozzle with the first filter box, allowing the first filter box to be fully and evenly rinsed without user intervention.

[0020] like Figures 1-62 As shown, this application discloses a swimming pool robot cleaning system, including a swimming pool robot 1000 and a base station 2000. The base station is at least used to clean the first filter box 1051 of the swimming pool robot, so that debris in the first filter box is transferred from the swimming pool robot or temporarily stored in the base station. Further, in some embodiments, the base station includes a base station body 20001 and at least one second filter box 21102. The second filter box is at least partially disposed on the base station body and configured to receive debris from the first filter box of the swimming pool robot and further filter it.

[0021] The Pool Robot 1000 is the main working unit of the cleaning system, responsible for performing cleaning tasks in the pool.

[0022] Base station 2000 serves as the support center for the cleaning system, providing services such as docking, cleaning, and charging for the pool robots. The base station body 20001 constitutes the main support structure of the base station, with a resting surface on its top for the pool robots to dock.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] Furthermore, regardless of whether the base station is used on land or on the ground, or placed in a pool or designated area, the base station also includes a pressurization component to ensure a high-speed water flow from the first nozzle. The pressurization component can be located in the waterway between the clean water source and the first nozzle. For example, the pressurization component includes, but is not limited to, a booster pump, a water hammer pump, a pressure tank, a mechanical pressurization device, an elevated water tank, etc., or it can increase the water flow velocity by reducing the diameter of the pipe adjacent to and connected to the first nozzle and / or reducing the orifice diameter at the water outlet (e.g., the nozzle).

[0040] In some embodiments, the pool robot can dock with the base station in the following ways: the pool robot docks with the base station underwater or on the water. The positional relationship between the pool robot and the base station when docking can be arranged horizontally or vertically. That is, when the pool robot is on the base station, it can lie on the base station body or carrier in a roughly vertical posture; or, it can be located on the base station body or carrier in a roughly horizontal posture.

[0041] For example, in some embodiments, the base station is located on the water, and at least a portion of the carrier is located underwater. When the base station docks with the pool robot, both the carrier and the pool robot are in a generally vertical position. At this time, the pool robot lies on the carrier to achieve docking between the base station and the pool robot, and the pool robot is located on the left or right side of the carrier. Alternatively, in another embodiment, the base station is located underwater, and when the base station docks with the pool robot, both the base station and the pool robot are in a generally horizontal position, and the pool robot is located above the base station body. Alternatively, in other embodiments, the base station is located on the water, and when the base station docks with the pool robot, both the base station and the pool robot are in a generally horizontal position, and the pool robot is located above the base station body.

[0042] In some embodiments, such as Figure 1 , Figure 62As shown, the base station also includes at least one second cleaning component 2170; the second cleaning component includes at least one first nozzle, which cleans the first filter box by spraying liquid onto it. When the pool robot stops on the base station body, it sprays liquid through the first nozzle to clean the first filter box, and the debris in the first filter box falls into the second filter box, thereby transferring the debris in the first filter box into the second filter box.

[0043] The pool robot 1000 is used to perform cleaning, disinfection, and rescue tasks in a target area. The target area can be any water-containing area where the pool robot 1000 can move. For example, the target area can include, but is not limited to, swimming pools, water tanks, oil wells, sewers, etc. The following description uses a swimming pool (or water tank) as an example. For a swimming pool, the pool includes at least a bottom and pool walls.

[0044] In some embodiments, such as Figure 58 , Figure 59 , Figure 60 As shown, the pool robot includes a first body 1001, at least one liquid inlet, at least one first filter box 1051, at least one liquid outlet, and at least one suction assembly. The liquid inlet allows pool liquid to enter the pool robot body 1001, enabling the robot to clean at least one of the pool bottom, pool walls, waterline, and water surface. The liquid outlet discharges the liquid filtered by the first filter box from the first body. The suction assembly generates suction to guide the liquid flow. The first filter box 1051 filters dust-laden water, retaining debris within it.

[0045] Under the action of the suction component, the dust-laden water in the pool is drawn into the first filter box 1051 through the liquid inlet and filtered by the first filter box 1051. The garbage carried in the liquid remains in the first filter box 1051. After being filtered, the liquid is discharged from the first main body through the liquid outlet after passing through the suction component.

[0046] In some embodiments, such as Figure 59 , Figure 60 As shown, the liquid inlet section includes at least a first inlet 1031, the liquid outlet section includes at least one first outlet 1041, and the suction assembly includes a main water pump 1061. The first inlet 1031, the first filter box 1051, the main water pump 1061, and the first outlet 1041 are sequentially fluidly connected to form a first water path for cleaning the bottom wall, side wall, or waterline of the pool. For example, in 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.

[0047] In other embodiments, such as Figure 59 , Figure 60 As shown, the liquid inlet section includes at least a second water inlet 1032, the liquid outlet section includes at least a first water outlet 1041, and the suction assembly includes a main water pump 1061; the second water inlet 1032, the first filter box 1051, the main water pump 1061 and the first water outlet 1041 are connected in sequence to form a second water channel for cleaning the water surface and water line.

[0048] In some embodiments, such as Figure 58 As shown, the first main body is provided with a fourth inlet 1016, which is connected to the first filter box, allowing the first nozzle to extend into or exit the pool robot through the fourth inlet. Since the first nozzle can extend into the first main body to spray liquid onto the first filter box, the liquid sprayed by the first nozzle can be effectively applied to the first filter box, ensuring its cleaning effect.

[0049] In some embodiments, a fourth inlet is provided on the first body, but the first nozzle does not extend into the first body. The first nozzle is located outside the first body, and the first nozzle sprays liquid from outside the first body through the fourth inlet to the first filter box, which can also achieve cleaning of the first filter box.

[0050] In some embodiments, the fourth inlet may be the first water inlet or the second water inlet; when the first body is provided with a pick-up and drop-off port, the fourth inlet may also be a pick-up and drop-off port, which is used for the user to put the first filter box into the first body or take out the first filter box from the first body; or, in other embodiments, the fourth inlet may be independent of the first water inlet and the second water inlet, and the pick-up and drop-off port may be provided on the first body.

[0051] In some embodiments, the pool robot also includes a baffle movably disposed at the fourth inlet, the baffle being used to open or close the fourth opening 2055.

[0052] In some embodiments, in order to discharge the waste from the first filter box, such as Figure 60 As shown, the first filter box includes at least one third opening 10531; and a first bottom cover, which can open or close the third opening. At least a portion of the third opening is located on the bottom of the first filter box. When the pool robot stops on the base station body, after the first bottom cover opens the third opening, the third opening can communicate with the third inlet 21101 of the second filter box, so that waste and liquid in the first filter box can be discharged from the third opening and fall into the second filter box through the third inlet.

[0053] In some embodiments, the second filter box has at least one filter surface for filtering liquids and waste entering therein, and retaining waste within the second filter box. The second filter box is provided with at least one third inlet, which serves as the entry point for waste into the second filter box. Figure 62As shown, when the pool robot is stationary on the base station body, the third inlet connects to the third opening of the first filter box, allowing the waste in the first filter box to enter the second filter box through the third opening and the third inlet. When the pool robot is stationary on the base station body, the first nozzle sprays liquid into the first filter box. After the first bottom cover 1054 of the first filter box opens the third opening, the waste 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 third opening and the third inlet. The waste remains in the second filter box, and the liquid is filtered by the second filter box and discharged from the base station body. This process collects or temporarily stores the waste from the first filter box into the second filter box, completing the cleaning of the first filter box. No user intervention is required during the cleaning process of the first filter box, achieving automatic cleaning.

[0054] In some embodiments, the second filter box includes a second frame and a second filter screen. The second filter screen is disposed on the second frame to form a filter surface. Alternatively, in other embodiments, the second filter box is a first filter bag, which can be a disposable filter bag or a reusable filter bag. If the second filter box is a disposable filter bag, when the first filter bag is full of garbage, the first filter bag can be directly discarded to replace it with a new one, without the need to clean the first filter bag. Alternatively, the second filter screen can be replaced with filter cotton, which can be disposed outside or inside the second frame.

[0055] In some embodiments, when the fourth inlet is provided with the aforementioned baffle, the baffle is used to open or close the fourth opening; the baffle opens the fourth inlet before the first nozzle switches from the retracted position to the extended position; and the baffle closes the fourth inlet after the first nozzle switches from the extended position to the retracted position.

[0056] In some embodiments, since the first nozzle extends into the first body through the fourth inlet and the baffle on the fourth inlet is in the open state, some of the liquid sprayed by the first nozzle into the first filter box will splash out of the pool robot from the fourth inlet. The splashed liquid will scatter on the base station or the pool shore, resulting in a poor user experience.

[0057] Therefore, in some embodiments, the second cleaning assembly further includes a second shielding cover 2177, which is used to close or shield the fourth inlet when the first nozzle is in the extended position; and to open the fourth inlet when the first nozzle is in the retracted position. The second shielding cover is disposed on at least one of the first delivery pipe and the support arm. As the first delivery pipe and the first nozzle move synchronously, when the first nozzle switches from the retracted position to the extended position, the second shielding cover shields the fourth inlet. When some liquid sprayed from the first nozzle splashes onto the fourth inlet, the second shielding cover prevents this liquid from splashing into the first body, thus preventing it from splashing outside the pool robot. When the first nozzle switches from the extended position to the retracted position, the second shielding cover moves with the first nozzle away from the fourth inlet, thereby not shielding the fourth inlet.

[0058] In some embodiments, the first nozzle is detachably disposed relative to the base station body to facilitate replacement of the first nozzle. The first nozzle 2173 can be selected from a single-hole nozzle, a multi-hole nozzle, a rotating nozzle, a non-rotating nozzle, a high-pressure nozzle, a low-pressure nozzle, etc. In some embodiments, the rotating nozzle is a mechanically driven rotating nozzle, that is, the rotation of the nozzle is achieved by a mechanical structure; or, the rotating nozzle is a recoil-driven rotating nozzle, that is, the rotation of the nozzle is achieved by the reaction force of the water flow, also known as a self-spinning nozzle.

[0059] In some embodiments, the first nozzle 2173 has at least one nozzle 21732 connected to a first delivery pipe. An external water source or water from a pool first flows into the first delivery pipe, and then the liquid flows through the first delivery pipe to the nozzle, which is used to spray liquid into the first filter box. When the first nozzle sprays liquid into the first filter box, the nozzle is positioned above at least a portion of the second filter box, causing the liquid sprayed by the nozzle to fall downwards into the second filter box along with debris in the first filter box.

[0060] In some embodiments, the first nozzle may be selected as a spinning nozzle. The spinning nozzle does not require an external motor to drive the nozzle to rotate. During the process of water spraying by the first nozzle, the liquid enters the first delivery pipe and is sprayed out from the first nozzle. The sprayed liquid exerts a reaction force on the nozzle to drive the first nozzle to rotate, so as to spray liquid in different directions in the first filter box, thereby enabling the first filter box to be thoroughly cleaned.

[0061] For example, in some embodiments, the nozzle is provided with at least one powered jet nozzle, from which liquid is ejected to form a high-speed liquid, driving the nozzle to rotate at least relative to the first delivery pipe. The powered jet nozzle is configured such that the ejected liquid generates a tangential thrust while producing a high-speed direct current flush, driving the nozzle to rotate continuously about its own axis.

[0062] In other embodiments, the nozzle is further provided with at least one non-powered spray nozzle, from which liquid cannot drive the nozzle to rotate relative to the first delivery pipe. The non-powered spray nozzle is used to spray liquid into the area of ​​the first filter box to supplement the cleaning blind spot of the powered spray nozzle.

[0063] In some embodiments, the first nozzle is stationary relative to the base station body, and the movement of the pool robot causes the first nozzle to passively pass through the fourth inlet into the first filter box or exit the pool robot.

[0064] It should be noted that when the first nozzle is stationary or fixed relative to the base station body, it means that the first delivery pipe is stationary or fixed relative to the base station body, not that the nozzle of the first nozzle is stationary or fixed relative to the base station body.

[0065] In other embodiments, the first nozzle is movably disposed relative to the base station body, and the movement of the first nozzle causes the first nozzle to actively extend into or out of the pool robot.

[0066] It should be noted that: the first nozzle being movable relative to the base station body refers to the first delivery pipe being movable relative to the base station body, not the nozzle being movable relative to the base station body.

[0067] In some embodiments, the first nozzle has an extended position and a retracted position relative to the base station. When the first nozzle moves from the retracted position to the extended position, the first nozzle extends from outside the pool robot into the first body through the fourth inlet. At this cleaning position, the first nozzle can spray liquid onto the first filter box to clean the first filter box. When the first nozzle moves from the extended position to the retracted position, the first nozzle exits outside the pool robot through the fourth inlet.

[0068] Furthermore, in some embodiments, the first nozzle is rotatably mounted on the base station body, and the first nozzle can switch between an extended position and a retracted position by rotation. For example, a support arm drives the first nozzle to rotate synchronously, and the support arm can pivot relative to the base station body to allow the first nozzle to extend into the first filter box or retract from the pool robot. For example, the support arm is rotatably mounted on a support base, which is fixed to the base station body; or, no support base is provided, and the support arm is rotatably connected to the base station body.

[0069] For example, in some embodiments, the first nozzle rotates horizontally about a generally vertical axis, such that during rotation, the first nozzle rotates through the fourth inlet into or out of the first body. For example, as... Figure 61 , Figure 62 As shown, the fourth inlet is the second water inlet, and the first nozzle rotates about a roughly vertical axis to switch between an extended position and a retracted position.

[0070] Alternatively, in other embodiments, the first nozzle rotates vertically about a generally horizontal axis, such that during rotation, the first nozzle rotates into or out of the first body via a fourth inlet. For example, the fourth inlet is a pick-and-place port, and the first nozzle rotates about a generally horizontal axis to switch between an extended position and a retracted position. Alternatively, in other embodiments, the first nozzle rotates about a third axis, which intersects the horizontal axis but is not a vertical axis.

[0071] In other embodiments, the first nozzle is retractably mounted on the base station body, and the first nozzle can switch between an extended position and a retracted position by telescopic movement. For example, the support arm drives the first nozzle to extend, so that the first nozzle extends into the first body; or, the support arm drives the first nozzle to retract, so that the first nozzle exits the first body.

[0072] Furthermore, in some embodiments, the first nozzle performs a telescopic movement in the horizontal direction. For example, when the fourth inlet is the second water inlet, the first nozzle performs a telescopic movement in the horizontal direction to extend into the first body through the second water inlet, or to exit the first body from the second water inlet.

[0073] Alternatively, in some embodiments, the first nozzle retracts or extends vertically. For example, when the fourth inlet is a pick-and-place port, the first nozzle retracts or extends vertically to pass through the pick-and-place port into the first body, or to exit the first body from the pick-and-place port.

[0074] In other embodiments, the first nozzle can extend and retract in a fifth direction, which intersects both the vertical and horizontal directions, allowing the first nozzle to pass through the fourth inlet and extend into or exit the first body. For example, the fifth direction may intersect the horizontal direction at angles of 5, 10, 15, 20, 30, 45, 60, 75, or 85 degrees.

[0075] In some embodiments, the second cleaning assembly further includes at least one second liquid inlet assembly 2179, the first nozzle 2173 is in fluid communication with the second liquid inlet assembly 2179 and the second liquid inlet assembly is in fluid communication with an external water supply component to provide cleaning liquid to the first nozzle.

[0076] Furthermore, in some embodiments, the second cleaning component further includes at least one driving component 2178, which is used to drive the first nozzle to switch between a first position and a second position, such that when the first nozzle moves from the second position to the first position, the first nozzle extends from outside the pool robot into the pool robot to spray liquid onto the first filter box, and when the first nozzle moves from the first position to the second position, the first nozzle retracts outside the pool robot to avoid the robot stopping or leaving the base station.

[0077] In one specific embodiment, the first nozzle is rotatably mounted on the base station body relative to the second liquid inlet assembly. The first nozzle can switch between a first position and a second position by rotating. The rotatable connection between the first nozzle and the second liquid inlet assembly 2179 allows the nozzle to switch spatial positions around its rotation pivot point within a limited area of ​​the base station body. The rotatable structure occupies less space, can better adapt to the limited installation environment inside the base station, and also reduces the risk of wear.

[0078] In one specific embodiment, at least one end of a second liquid inlet component is rotatably embedded in one end of a first liquid inlet component, or rotatably sleeved on one end of the first liquid inlet component, so that the inner cavity of the second liquid inlet component communicates with the inner cavity of the first liquid inlet component. When a rotatable embedded fit is used, one end of the second liquid inlet component is a cylindrical structure adapted to the inner cavity of the first liquid inlet component; when a rotatable sleeve fit is used, one end of the second liquid inlet component can be an annular sleeve structure. Both fit methods ensure that the inner cavities of the two components are coaxially aligned and that fluid communication is uninterrupted during rotation.

[0079] In one specific embodiment, such as Figure 4 As shown, the second cleaning assembly 2170 further includes a first liquid inlet assembly 2180, which includes at least a first liquid inlet component 21801, and a second liquid inlet assembly 2179, which includes at least a second liquid inlet component 21791. One end of the first liquid inlet component and one end of the second liquid inlet component are rotatably connected, and the other end of the first liquid inlet component is connected to the first nozzle. The other end of the second liquid inlet component is used to connect to the water supply component. The drive assembly drives the first liquid inlet component to rotate relative to the second liquid inlet component. This arrangement allows the first nozzle 2173 to rotate around the connecting axis with the first liquid inlet component 21801 without affecting the stable delivery of liquid. The power of the drive assembly 2178 directly acts on the first liquid inlet component 21801, causing it and the first nozzle 2173 to switch positions in the same manner of movement.

[0080] For the cleaning water source, the cleaning water source can be liquid from a swimming pool or municipal water. For example, in some embodiments, the first water source inlet can be connected to an indoor or outdoor faucet in a user's home via a first pipe to provide cleaning water to the first showerhead. In some embodiments, to facilitate the user's connection of the first pipe to the first water source inlet, the first water source inlet is located on a side wall of the base station body and exposed to the external environment, making it convenient for the user to install or remove the first pipe from the side of the base station body.

[0081] In some embodiments, the liquid sprayed by the first nozzle, i.e., the cleaning water source or cleaning liquid, can be water from a swimming pool, pool, or river; or tap water supplied to a water tank, faucet, or shower head; or cleaning liquid to further remove oil stains, stubborn dirt, etc. from the filter screen; or a mixture of any two or more of the above water sources, for example, a mixture of tap water and cleaning liquid; or a mixture of water from a swimming pool, pool, or river and cleaning liquid.

[0082] In some embodiments, the cleaning water source is provided by a water supply component. For example, when the cleaning water source is liquid in a swimming pool, pond, river, or water tank, the water supply component can be a swimming pool, pond, river, or water tank. In this case, the second cleaning component may also include a first water pump to supply liquid from the swimming pool, pond, river, or water tank to the first spray head. Alternatively, when the cleaning water source is an indoor or outdoor faucet in a user's home or a sprinkler head on a lawn, the water supply component can be a faucet or a sprinkler head. In this case, the second cleaning component may also include a first water pump connected to the faucet or sprinkler head to provide cleaning water to the first spray head. Alternatively, in this case, the second cleaning component does not include a first water pump, and the faucet or sprinkler head directly provides cleaning water to the first spray head.

[0083] In the above embodiment, the water supply component, the second liquid inlet component, the first liquid inlet component, and the first nozzle are sequentially fluidly connected to form a fourth water path, thereby delivering clean water to the first nozzle, and the first nozzle sprays liquid onto the first filter box to clean the first filter box.

[0084] In some embodiments, the second liquid inlet component can be fixed to the faucet, shower head or water pump using 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.

[0085] In some embodiments, the user can manually or automatically control the faucet to open or close, thereby controlling the first nozzle to spray liquid onto or stop spraying liquid onto the first filter box.

[0086] Alternatively, in other embodiments, the second cleaning component further includes at least one valve located on the fourth water path, upstream of the first nozzle, for connecting or disconnecting the water flow between the faucet (or cleaning water source) and the first nozzle, thereby controlling the first nozzle to spray liquid into or stop spraying liquid into the first filter box. Due to the valve, the faucet can be normally open, and the processor on the base station or pool robot controls the opening or closing of the valve to control the first nozzle to start or stop spraying liquid. In this embodiment, the faucet is normally open, eliminating the need for manual control by the user, further eliminating the need for user intervention during the cleaning process of the first filter box; or, in other words, no faucet is required between the cleaning water source and the first water source inlet. The valve can be installed on at least one of the support arm, support base, and the pipeline between the first water source inlet and the faucet. In some embodiments, the valve can be selected as a one-way valve, for example, at least one of a solenoid valve, baffle valve, ball valve, butterfly valve, etc.

[0087] Furthermore, when the valve's outlet port is located at the first water source inlet, the first water source inlet can be either not exposed or exposed to the external environment. When the valve's inlet port is exposed to the external environment, it is convenient for the user to connect the pipeline to the valve's inlet port and the faucet, without requiring the user to install the valve. If the user needs to install the valve, then the first water source inlet is exposed to the environment, which facilitates the user's installation of the valve and the first pipeline.

[0088] In some embodiments, the valve may be disposed on the first inlet component and / or the second inlet component. For example, in some embodiments, the valve is disposed on the first delivery pipe, the support arm, or the first connecting pipe; or, the inlet end of the valve is connected to the support arm and the outlet end of the valve is connected to the first delivery pipe; or, the inlet end of the valve is connected to the first connecting pipe and the outlet end of the valve is connected to the support arm. In other embodiments, the valve is disposed on the second connecting pipe, the second delivery pipe, or the third delivery pipe; or, the inlet end of the valve is connected to the second delivery pipe and the outlet end of the valve is connected to the second connecting pipe; or, the inlet end of the valve is connected to the third delivery pipe and the outlet end of the valve is connected to the second connecting pipe.

[0089] For example, in one specific embodiment, the second liquid inlet component further includes at least one one-way valve. The one-way valve is located on the second liquid inlet component and only allows water from the water supply component to flow unidirectionally from the second liquid inlet component to the first liquid inlet component. This arrangement can effectively restrict the flow direction of the base station cleaning liquid path without changing the overall structural layout, ensuring that the liquid movement path always remains in a single direction: from the external water supply component into the second liquid inlet component 21791 and flowing to the first liquid inlet component 21801. This prevents internal liquid from flowing back into the water source or back into the second liquid inlet component due to pressure fluctuations during the cleaning process or when the nozzle is withdrawn.

[0090] In one specific embodiment, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the second liquid inlet component includes at least a second connecting pipe, one end of which is rotatably connected to the first liquid inlet component; a second delivery pipe, one end of which is connected to the second connecting pipe, and the other end of which is used to connect to the water supply component; a one-way valve is provided on the second connecting pipe or the second delivery pipe; or, the water inlet end of the one-way valve is connected to the second delivery pipe, and the water outlet end of the one-way valve is connected to the second connecting pipe.

[0091] In some embodiments, the second delivery pipe 21793 can be a rigid pipe, a flexible pipe, or an explosion-proof pipe, etc., so that the liquid circuit can maintain a stable connection under different water supply environments and installation conditions, and provide high safety under high-speed impact or external force pulling.

[0092] In some embodiments, the drive component may be disposed within the base station body or within the support base. The drive component includes, but is not limited to, motor drive, hydraulic drive, pneumatic drive, magnetic drive, mechanical drive, etc.

[0093] For example, in some embodiments, the drive assembly includes a motor 2174 disposed within a support base, the motor being rotatably connected to the first nozzle, and the motor driving the first nozzle to rotate to switch between an extended position and a retracted position.

[0094] Alternatively, in some embodiments, the drive assembly further includes at least one transmission assembly disposed between the drive assembly and the first nozzle, for transmitting the driving force provided by the drive assembly to the first nozzle to achieve rotation of the first nozzle. The transmission assembly may be configured as a gear mechanism, linkage mechanism, cam mechanism, etc.

[0095] In one specific embodiment, such as Figure 8 , Figure 11 , Figure 20As shown, the drive assembly 2178 includes at least a motor 2174 and at least one transmission assembly 2181. The transmission assembly 2181 includes at least a second transmission wheel 21811, which is connected to the first liquid inlet component. The motor drives the second transmission wheel to rotate, thereby driving the first liquid inlet component and the first nozzle to rotate. When the motor drives the second transmission wheel to rotate around a preset axis, the transmission assembly structure drives the first liquid inlet component to rotate synchronously, thereby driving the support arm and the first nozzle to switch between a first position and a second position. The rotation process does not affect the liquid delivery function of the first liquid inlet component. Further, the second transmission wheel 21811 is rotatably sleeved on the second liquid inlet component. One end of the second liquid inlet component passes through the second transmission wheel 21811 and is rotatably connected to one end of the first liquid inlet component. The second transmission wheel 21811 is connected to the first liquid inlet component in a transmission manner, so that the motor 2174 drives the second transmission wheel 21811 to rotate, thereby driving the first liquid inlet component and the first nozzle 2173 to rotate and switch between the first position and the second position. In one embodiment, the second transmission wheel 21811 may be a gear-type transmission wheel, a friction transmission ring, a pulley structure, etc., to adapt to different output torque requirements.

[0096] In some embodiments, the transmission assembly further includes at least one first transmission wheel, the output shaft of the motor is connected to the first transmission wheel, and the first transmission wheel is drivingly connected to a second transmission wheel. In some embodiments, the first transmission wheel and the second transmission wheel transmit power through any one or a combination of gear meshing transmission, belt transmission, sprocket transmission, and track transmission; furthermore, the transmission assembly also includes at least one third gear to change the transmission direction or adjust the reduction ratio.

[0097] In some embodiments, such as Figure 2 , Figure 3 , Figure 6 , Figure 18 , Figure 20 , Figure 29 , Figure 48 , Figure 49 As shown, the second cleaning assembly 2170 also includes a support arm 2172 (which can also be described as a nozzle support arm), one end of which is disposed on the base station body, and the other end is connected to the first nozzle. For example, one end of the support arm is fixedly or movably disposed on the base station body, and the other end of the support arm is connected to the first delivery pipe. Further, for example, one end of the support arm is fixedly or movably disposed on the top or side wall of the base station body, so that the first nozzle is located above the top of the base station body.

[0098] In one specific embodiment, such as Figure 4 , Figure 8As shown, the first liquid inlet component 21801 includes at least one support arm 2172. One end of the support arm 2172 is rotatably connected to one end of the second liquid inlet component 21791 and forms fluid communication, while the other end is detachably connected to the first nozzle 2173. Further, a transmission assembly is drively connected to the support arm, and a motor 2174 drives the transmission assembly 2181 to rotate, thereby causing the first liquid inlet component and the first nozzle to rotate synchronously relative to the second liquid inlet component. In some embodiments, the support arm is an integrally formed hollow tube; or, the support arm is composed of multiple segments connected by a sealed rotating shaft. In some embodiments, the support arm and the first nozzle can be connected by a snap-fit ​​connection, a threaded connection, or a quick-release structure to facilitate daily maintenance and disassembly / cleaning. In different embodiments, the support arm and the second liquid inlet component rotate through a rotary joint, a sealed bearing, or a spherical seal structure to prevent leakage at the connection point. In some embodiments, the drive assembly may use a DC motor, brushless motor, stepper motor or geared motor as the power source and cooperate with gear set, worm gear, rack drive or linkage mechanism to form a transmission assembly to stably transmit motor torque to the support arm.

[0099] In one specific embodiment, such as Figure 8 , Figure 9 , Figure 18 , Figure 19 , Figure 20 , Figure 32 , Figure 33 As shown, the first liquid inlet component further includes a first connecting pipe 21784. One end of the first connecting pipe is rotatably connected to one end of the second liquid inlet component, and the other end of the first connecting pipe is fixedly connected to one end of the support arm. The first connecting pipe is connected to a transmission assembly for transmission, thereby connecting the support arm to the transmission assembly. When the motor drives the transmission assembly to rotate, it drives the support arm to rotate around the axis of the second liquid inlet component via the first connecting pipe, thereby causing the first nozzle to switch positions. In some embodiments, the first connecting pipe adopts an integrally formed or segmented hollow pipe structure.

[0100] In one specific embodiment, one end of the first connecting tube is rotatably sleeved on or embedded within one end of the second liquid inlet component; the other end of the first connecting tube is sleeved on or embedded within one end of the support arm, so that the inner cavity of the first liquid inlet component, the inner cavity of the first connecting tube, and the inner cavity of the support arm are sequentially connected. Both configurations ensure that the inner cavities of the second liquid inlet component, the first connecting tube, and the support arm are coaxially aligned and sequentially connected, guaranteeing smooth liquid flow.

[0101] In one specific embodiment, such as Figure 7As shown, the support arm 2172 includes a first connecting arm 21724 and a second connecting arm 21725. One end of the second connecting arm is engaged with a transmission assembly to receive rotational force. One end of the first connecting arm intersects and is fixedly connected to the other end of the second connecting arm to change the direction of water flow within the second connecting arm. The other end of the first connecting arm is connected to a first nozzle. When the second connecting arm rotates with the transmission assembly, it drives the first connecting arm and the first nozzle to rotate synchronously around the axis of the second liquid inlet component, thereby switching between a first position and a second position. In specific implementations, the first connecting arm 21724 and the second connecting arm can be hollow fluid tubes or reinforcing arms with built-in channels. In some embodiments, the intersection angle between the first connecting arm and the second connecting arm can be a right angle, an acute angle, or an obtuse angle to accommodate different spray angle requirements.

[0102] In some embodiments, such as Figure 8 As shown, the first liquid inlet component 21801 further includes at least one first delivery pipe 21802. One end of the first delivery pipe 21802 is connected to the other end of the support arm 2172, and the other end of the first delivery pipe is connected to the first nozzle. At least a portion of the first delivery pipe near the first nozzle (such as the guide portion 218021) has a longitudinal cross-sectional area smaller than the longitudinal cross-sectional area of ​​the support arm near the corresponding portion of the first nozzle (such as the first connecting portion 218022), so as to form a liquid delivery path that gradually narrows from the support arm to the first nozzle. In specific embodiments, the first delivery pipe can be a rigid pipe or a flexible pipe, etc. In some embodiments, the first delivery pipe can be a multi-segment structure or a one-piece molded structure. In some embodiments, the first delivery pipe can be a tapered pipe or a constant-diameter pipe.

[0103] In some embodiments, such as Figure 51 , Figure 52 , Figure 53 , Figure 55 As shown, the transmission assembly includes at least a first gear 2175 and a second gear 2176. The first gear is fixed to the output shaft of the motor, and the second gear is installed at one end of the support arm. The first gear and the second gear mesh. When the motor drives the first gear to rotate, it drives the second gear and the support arm connected thereto to rotate, thereby driving the first nozzle to rotate to switch between the extended position and the retracted position.

[0104] In some embodiments, when the motor 2174 is not turned on, the user can manually drive the support arm to rotate or extend the first nozzle, thereby switching the first nozzle between the extended and retracted positions. For example, when the user wants to manually intervene to drive the first nozzle to rotate; or when the first nozzle fails to switch between the retracted and extended positions, the user can manually drive the first nozzle to rotate, thereby switching the first nozzle between the retracted and extended positions.

[0105] As a preferred example of this application, the first nozzle can be driven by a motor or manually. The drive assembly 2178 also includes a clutch structure configured to disconnect the motor drive connection during manual operation. As the core switching mechanism between the two drive modes, the clutch structure can stably transmit torque during motor drive and automatically disengage the power coupling during manual operation, thereby preventing structural damage to the internal gear system of the motor caused by human operation and significantly improving the safety and service life of the system.

[0106] For example, in some specific embodiments, such as Figure 19 As shown, the drive assembly also includes a clutch mechanism 21812, which can be mounted between the first liquid inlet component and the second transmission wheel. This allows the first liquid inlet component and the second transmission wheel to rotate synchronously when driven by the motor (i.e., when the motor is running); and to rotate relative to the second transmission wheel when not driven by the motor (i.e., when the motor is not running but is subjected to external driving force (e.g., manual drive)). In other words, the clutch mechanism has two operating states: the first state, when the motor outputs power, fixes the first liquid inlet component and the second transmission wheel, causing them to rotate synchronously; the second state, when the motor stops driving and the first liquid inlet component is subjected to external driving force, releases the fixation between the first liquid inlet component and the second transmission wheel, allowing the first liquid inlet component to rotate independently relative to the second transmission wheel.

[0107] In some embodiments, the clutch mechanism may employ a ball pin slot structure to automatically slip when the torque exceeds a threshold, or a friction clutch structure in which elastic pressure plates and meshing teeth cooperate to generate relative sliding under external force, or a magnetic attraction structure to allow separation and relative rotation when the magnetic attraction force is insufficient.

[0108] In some specific embodiments, such as Figure 13 , Figures 14-17 , Figures 18-28 As shown, the clutch mechanism 21812 includes at least one telescopic component 21786 and at least two first mating parts. The at least two first mating parts are spaced apart along the rotation direction of the first liquid inlet component. Each first mating part 21814 has a recessed area 218141, and a protruding area 218142 is formed between two adjacent first mating parts. One of the telescopic component 21786 and the first mating part 21814 is disposed on the second transmission wheel, and the other is disposed on the first liquid inlet component. In the first state, the telescopic component 21786 is embedded in the recessed area 218141 so that the first liquid inlet component rotates synchronously with the second transmission wheel 21811. In the second state, the telescopic component 21786 can pass through at least one protruding area and rotate from the previous recessed area to the next recessed area, so as to allow the first liquid inlet component 21801 to rotate independently relative to the second transmission wheel 21811 under the action of external force.

[0109] In some embodiments, the telescopic component may be in the form of an elastic push rod, with a spring providing preload so that it naturally embeds into the recessed area when there is no external force interference; in other embodiments, the telescopic component may be a sliding column or a structure with a flexible deformable section to adapt to different installation directions and stroke requirements; and the multiple first mating parts may be evenly distributed or non-equidistantly arranged to adapt to specific switching angle requirements; the raised area formed between adjacent first mating parts may be a stepped slope or an arc surface, etc.

[0110] In one specific embodiment, such as Figure 17 As shown, the first mating component 21814 is a first concave tooth 218143. The groove of each first concave tooth forms a recessed area 218141, and the tooth tip between two adjacent first concave teeth forms a first convex tooth 218144, i.e., a raised area 218142. Further, one of the telescopic component 21786 and the first concave tooth 218143 is assembled on the end face or outer periphery of the second transmission wheel 21811, and the other is assembled on the corresponding end face or outer periphery of the first liquid inlet component 21801. In the first state, the telescopic component 21786 is embedded in the groove of the first concave tooth 218143 to achieve circumferential fixation, so that the first liquid inlet component rotates synchronously with the second transmission wheel. In the second state, the telescopic component overcomes its own elastic force and disengages from the current groove under the action of external force, slides along the tooth tip of the first convex tooth, and then embeds into the groove of the adjacent first concave tooth, so as to realize the independent rotation of the first liquid inlet component 21801 relative to the second transmission wheel 21791. In some embodiments, the first concave teeth may be arranged at equal intervals or at non-equal intervals. In some embodiments, the sidewalls of the first concave teeth may be designed as straight walls, inclined walls, or composite curved surfaces. In some embodiments, the first convex teeth may be pointed or arc-shaped.

[0111] In some specific embodiments, such as Figure 23 , Figure 24 As shown, the first mating part 21814 consists of grooves or holes spaced circumferentially along the rotation direction of the first liquid inlet component. The groove cavity or the inner cavity of the hole forms a recessed area 218141, and the solid area between two adjacent grooves or holes forms a raised area 218142. In some embodiments, the groove can be a straight groove, an arc groove, a conical groove, or a closed hole, a semi-through hole, or a stepped hole. In some embodiments, the raised area can be arc-shaped, pointed, planar, etc. In some embodiments, the grooves and raised areas can be arranged at equal or unequal intervals.

[0112] In some specific embodiments, such as Figure 14 , Figure 15 , Figure 21 , Figure 23 , Figure 24As shown, the first connecting pipe 21784 has an outwardly extending first boss 217841, and the second transmission wheel 21811 has a second boss 21815 distributed opposite to the first boss 217841. One of the telescopic component and the first mating component is assembled on the first boss, and the other is assembled on the second boss. In some embodiments, the first boss can be integrally formed on the first liquid inlet component, or it can be a separate component fixedly connected to its outer periphery. In some embodiments, the second boss can be integrally formed on the second transmission wheel, or it can be a separate component fixedly connected to its outer periphery. In some embodiments, a groove, hole, or tooth can be formed on the first boss, and the telescopic component is disposed on the second boss; or, a groove, hole, or tooth can be disposed on the second boss, and the telescopic component is disposed on the first boss. In some embodiments, the shapes of the first boss and the second boss can be wedge-shaped, annular, fan-shaped, or multi-segmented structures, etc.

[0113] In some specific embodiments, such as Figure 20 , Figure 21 , Figure 53 As shown, the second transmission wheel 21811 is the second gear 2176, the second tooth 21816 is located on one end of the second gear, the second boss is provided on one end of the second gear, and the distribution area of ​​the second boss avoids the area where the second tooth of the second gear is located.

[0114] In some specific embodiments, such as Figure 16 , Figure 26 As shown, the telescopic assembly 21786 includes at least a telescopic head 217861 and at least one elastic element 217865. The elastic element 217865 applies a preload, elastic force, or bias force to 217861. Under the action of the preload, elastic force, or bias force, the telescopic head tends to remain in the recessed area (without external force). When the telescopic head 217861 abuts against the protruding area 218142, the elastic element 217865 deforms to store energy. When rotating to the next recessed area 218141, the elastic element releases the elastic force, causing the telescopic head to re-enter the current recessed area. That is, in the first state, at least a portion of the telescopic head extends into the recessed area; in the second state, the telescopic head can pass through at least one raised area, rotating from the previous recessed area to the next; wherein, the telescopic head retracts to abut against the raised area, forcing the elastic element to deform and store energy; when the telescopic head rotates to the next recessed area, the elastic element releases the stored energy, causing at least a portion of the telescopic head to extend into the current recessed area. In actual use, in the initial state, such as Figure 25 As shown, the ball head of the telescopic head abuts against the recessed area 218141, and the telescopic head is in the first state. Under the action of external force, the telescopic head rotates together with the support arm 2172, and the telescopic head compresses the elastic element 217865 to perform a retracting movement, and then abuts against the protruding area 218142. At this time, the telescopic head is in the second state, as shown. Figure 27 , Figure 28 As shown, the telescopic head then rotates further with the support arm 2172 to the next recessed area 218141. Under the action of the elastic element 217865, the ball head extends, causing at least a portion of the ball head to extend into the recessed area. At this time, the telescopic head returns to the first state, and its structural form is as follows. Figure 25 As shown.

[0115] In some embodiments, the telescopic assembly further includes a third mounting base 217866, a first mounting cavity 217867 having at least one open end, and a telescopic head slidably disposed at least at the open end of the mounting cavity; an elastic element is disposed within the first mounting cavity; in a first state, at least a portion of the telescopic head is located outside the open end to extend into a second recessed area; in a second state, at least a portion of the telescopic head retracts into the first mounting cavity, allowing the telescopic head to pass through a protruding area; when the telescopic head rotates to the next recessed area, at least a portion of the telescopic head extends out of the open end to extend into the current recessed area.

[0116] In some embodiments, the telescopic head can be cylindrical, spherical, toothed, frustoconical, or irregularly shaped. In other embodiments, the elastic element can be a compression spring, leaf spring, bending spring, rubber elastomer, or magnetic elastic element. In some embodiments, the elastic element can be located inside the telescopic assembly, on the first boss, or on the second boss.

[0117] In some embodiments, when the telescopic assembly is disposed on the first liquid inlet component, one end of the elastic element is connected to the first liquid inlet component and the other end is connected to the telescopic head; or, in another embodiment, when the telescopic assembly is disposed on the second transmission wheel, one end of the elastic element is connected to the second transmission wheel and the other end is connected to the telescopic head. Further, when the telescopic assembly is assembled on the first boss, one end of the elastic element is engaged with the first boss or the first liquid inlet component, and the other end is engaged with the telescopic head; when the telescopic assembly is assembled on the second boss, one end of the elastic element is engaged with the second boss or the second transmission wheel, and the other end is engaged with the telescopic head, and the elastic element always applies a preload force to the telescopic head.

[0118] In some embodiments, the connection between the two ends of the elastic element 217865 and the telescopic head and the first liquid inlet component or the second transmission wheel can be direct or indirect. For example, Figure 16 As shown, in one embodiment, the telescopic head 217861 is toothed, and the elastic element is a compression spring, with one end of the compression spring directly connected to the telescopic head and the other end directly connected to the first liquid inlet component; or, in another embodiment, as shown... Figure 22 , Figure 26 , Figure 28As shown, the telescopic head 217861 is spherical, and the elastic element is a compression spring. One end of the compression spring is directly connected to the telescopic head, and the other end is indirectly connected to the first liquid inlet component. For example, the compression spring is installed inside the telescopic head, and the other end of the compression spring is indirectly connected to the first liquid inlet component through the telescopic head.

[0119] In some specific embodiments, such as Figure 13 , Figure 16 As shown, the telescopic head is toothed, for example, a third tooth 217862 is provided on the telescopic head 217861; the telescopic head is also provided with a third limiting part 217863 for limiting the axial movement of the telescopic head. The telescopic head is also provided with a sliding rod 217864. The third tooth 217862 is provided on the side of the telescopic head 217861 near the second gear 2176, and the sliding rod 217864 is provided on the telescopic head 217861 and extends away from the third tooth 217862. Correspondingly, a first groove 217251 is provided at the end of the second connecting arm 21725 near the first boss 217841. An elastic element 217865 (such as a compression spring) is sleeved on the sliding rod 217864 and extends into the first groove 217251. The telescopic head 217861 is embedded in the first boss 217841 and can be limited in stroke by the third limiting part 217863.

[0120] In some specific embodiments, such as Figures 22-28 As shown, the telescopic head is spherical. For example, the telescopic component 21786 is a positioning bead 21813. The positioning bead includes a ball head (i.e., the telescopic head), an elastic element 217865, and a third mounting base. The elastic element is disposed in the first mounting cavity of the third mounting base. The ball head is slidably disposed at least at the opening end of the first mounting cavity. One end of the elastic element is connected to the ball head, and the other end is connected to the mounting base. The ball head can slide and rotate relative to the third mounting base at the same time.

[0121] In some specific embodiments, such as Figure 32 , Figure 13 , Figure 19As shown, the first transmission wheel is the first gear 2175, and the second transmission wheel is the second gear 2176. The first gear 2175 is connected to the output shaft of the motor 2174, and the second gear 2176 meshes with the first gear 2175 for transmission. In this embodiment, after the motor 2174 starts, it drives the first gear 2175 to rotate. The first gear 2175 meshes with the second gear 2176 for transmission. At this time, the elastic element 217865 pushes the telescopic head 217861 so that the third convex tooth 217862 or the ball head automatically embeds into the first groove 21761 of the second gear 2176. The power is transmitted to the first liquid inlet component 21801 through the clutch mechanism. The motor 2174 outputs torque and transmits power steadily between itself and the support arm 2172, thereby driving the support arm 2172 to drive the first nozzle to rotate. When manual intervention is required, the user can directly operate the device manually. Rotating the support arm 2172, the motor is in the off state, so it will not drive the second gear to rotate. The first groove on the second gear remains stationary. At this time, the support arm 2172 drives the telescopic head 217861 to overcome the elastic force of the elastic element 217865, causing the third protrusion 217862 or ball head to disengage from the first groove 21761 to disconnect the transmission connection, preventing reverse torque from acting on the motor 2174 and preventing damage to the motor. When the driving force is removed, the elastic element 217865 releases its stored energy, and the third protrusion 217862 or ball head continues to be embedded in the first groove 21761 and enters a standby state. By setting a clutch mechanism, the first nozzle can smoothly switch between motor-driven and manual-driven operation modes, thus meeting the needs of both automated operation and emergency manual control.

[0122] Alternatively, in some other embodiments, the second telescopic head is the first friction plate, and the second mating part is the second friction plate. In this case, there is no need to provide a second recessed area on the second mating part. The first liquid inlet component and the second transmission wheel have a first state and a second state only through the conversion between the static friction force and the dynamic friction force between the first friction plate and the second friction plate.

[0123] In some embodiments, a sealing assembly 21787 is provided between the first connecting pipe 21784 and the support arm 2172 and / or between the first connecting pipe 21784 and the second connecting pipe 21785. The sealing assembly may be a waterproof sealing ring, a gasket, an oil seal, etc.

[0124] For example, in some specific embodiments, such as Figure 37As shown, the first connecting pipe 21784 includes a first pipe body 217842. A first boss can be disposed at one end of the first pipe body, and the first boss and the first pipe body are stepped together. The first boss is disposed on the side near the second gear. A second groove 217843 is disposed on the side of the first pipe body away from the first boss. A first waterproof sealing ring 217871 is disposed in the second groove 217843 to achieve a sealed connection between the first connecting pipe and the support arm. The first boss and the first pipe body can be disposed separately or integrally.

[0125] In some specific embodiments, such as Figure 38 As shown, the second connecting pipe 21785 includes a second pipe body portion 217851. A third groove 217852 is provided at one end of the second pipe body portion 217851, and a second waterproof sealing ring 217872 is provided within the third groove 217852 to achieve a sealed connection between the second pipe body portion and the first pipe body portion. Furthermore, the second connecting pipe also includes a second limiting portion 217853. The second pipe body portion is embedded inside the first pipe body portion and is limited by the second limiting portion cooperating with the first boss. The other end of the second pipe body portion 217851 extends into the second gear 2176 and is connected through a first bearing, so that while the first connecting pipe rotates with the second gear, the second connecting pipe 21785 remains stationary.

[0126] In some specific embodiments, such as Figure 9 As shown, at least two first bearings 21788 are assembled between the second gear 2176 and the second connecting pipe 21785. The two first bearings are distributed along the axial direction of the second connecting pipe 21785 to form a double bearing support. The two first bearings share the load and limit the circumferential movement of the second gear 2176. The double support structure enables self-alignment to allow for smaller installation and rotational errors. In some embodiments, the first bearings may be deep groove ball bearings, needle roller bearings, angular contact bearings, or ceramic bearings to adapt to different load environments and corrosion resistance requirements.

[0127] In some specific embodiments, such as Figure 9 As shown, limiting members disposed on the second gear 2176 and / or the second connecting pipe 21785 axially limit the first bearing between the second gear and the second connecting pipe. For example, the limiting members include at least one first step 218111 formed on the second gear 2176 and at least one second step 217855 formed on the second connecting pipe 21785, so that each first bearing, in the installed state, abuts against the corresponding step and is thus limited to a preset axial position, thereby maintaining stable support and rotational engagement between the first bearing and the gear transmission assembly.

[0128] In some specific embodiments, such as Figure 9As shown, at least one retaining ring 21817 is provided between the second connecting pipe 21785 and the second gear 2176 to axially limit the second gear, so that the second gear is held in a preset axial position without axial displacement during operation. In some embodiments, the retaining ring can be a metal retaining ring or an elastic retaining ring, etc. In some instances, the retaining ring can adopt a combined structure or a segmented retaining ring.

[0129] In some embodiments, such as Figure 48 , Figure 50 , Figure 51 , Figure 55 As shown, the second cleaning component also includes a support base 2171, through which a support arm is mounted on the base station body. For example, one end of the support base is mounted on the base station body, and the other end is detachably or non-detachably connected to the support arm. For example, one end of the support base is mounted on the top or side wall of the base station body.

[0130] In some examples, such as Figure 7 , Figure 10 , Figure 11 , Figure 20 , Figure 52 As shown, the support base includes at least a motor mount 21781, which is used to mount the motor and fix it to the base station body.

[0131] In some embodiments, such as Figure 2 , Figure 7 , Figure 11 , Figure 20 , Figure 54 As shown, the support base also includes a first protective cover 21711, which is fixed to the motor mount or the base station body. The first protective cover 21711 at least partially protrudes from the base station body or is flush with the top of the base station body; or, the first protective cover is at least partially embedded in the base station body. In some embodiments, the motor is securely connected to the base station body by any of the following methods: screws, clips, welding, or sleeves; the first protective cover is securely connected to the motor mount or the base station body by any of the following methods: screws, clips, welding, or sleeves.

[0132] In some embodiments, the support base further includes at least one bushing 21782, which is fixedly connected to the motor base and / or the first protective cover. For example, the first protective cover and the bushing are fixedly connected by at least one of the following methods: protrusion, groove, and screw. In some embodiments, the first protective cover is positioned by a protrusion embedded in a groove on the outer periphery of the bushing, or it can be locked by multiple screws to the threaded holes of the bushing, or the groove can be engaged with the annular flange on the outer wall of the bushing for limiting. In some embodiments, such as Figure 32 , Figure 34 As shown, bushing 21782 can be equivalent to the first protective cover. The first protective cover prevents dust on the one hand and acts as the bushing on the other.

[0133] In some examples, such as Figure 9 As shown, at least one second bearing 21783 is provided between the support arm and the first protective cover. The second bearing 21783 is used to support the rotation of the support arm 2172 relative to the first protective cover 21711 and improve rotational stability. In another embodiment, two second bearings are provided vertically between the support arm and the first protective cover.

[0134] In some examples, this application also discloses an embodiment of a clutchless mechanism in which the second gear and the support arm are fixedly connected. For example... Figures 48-54 As shown, the second gear 2176 is fixedly engaged with the support arm via a groove, protrusion, or screw, and the second gear drives the support arm to rotate. Further, as... Figure 53 , Figure 54 As shown, a first connecting cover 21726 is provided on the side of the support arm 2172 near the drive assembly 2178. The first connecting cover 21726 has a third connecting hole 217261 and an insertion end 21727 extending towards the drive assembly. The insertion end 21727 can be inserted into the inner surface of the second gear 2176 and is limited by the cooperation of the guide protrusion 217271 and the fourth groove 21763. The guide protrusion 217271 is provided on the outer surface of the insertion end 21727, and the fourth groove 21763 is provided on the inner surface of the second gear 2176. The second gear 2176 has a fourth connecting hole 21762 corresponding to the third connecting hole. The third connecting hole and the fourth connecting hole are fixed by connecting screws to realize the connection between the support arm and the second gear. Furthermore, in this embodiment, the bushing 21782 is provided with a first connecting hole 217825, and the first protective cover 21711 is provided with a second connecting hole 217111 corresponding to the first connecting hole 217825. The first connecting hole and the second connecting hole are fixed by screws to realize the connection between the bushing and the first protective cover.

[0135] In some embodiments, such as Figure 2 , Figure 7 , Figure 20 As shown, the support base 2171 also includes a second protective cover 21712, which is used to cover the first protective cover and is detachably connected to the first protective cover. For example, the first protective cover and the second protective cover are connected by screws.

[0136] In other embodiments, such as Figure 7 , Figure 20As shown, the support base 2171 also includes a third protective cover 21713, which is used to cover the second protective cover and is detachably connected to the second protective cover. For example, the second and third protective covers are magnetically connected. In some embodiments, the top of the third protective cover is substantially flush with the top of the base station body or at least partially protrudes upward from the top of the base station body. In the base station structure provided in this application, the support base introduces a multi-layered protective assembly of a first protective cover, a second protective cover, and a third protective cover, forming a closed protection system that covers from the inside out. The first protective cover is fixedly installed and integrally embedded inside the base station body, so that the internal drive structure, rotating parts, and liquid inlet connection area are protected from external water flow, impurity particles, and user operation interference during daily use. The second protective cover is detachably set and covers the first protective cover, enabling quick assembly and disassembly. This allows maintenance personnel to easily remove the second protective cover without damaging the base station body, and then simultaneously remove the third protective cover, the first liquid inlet component, the first nozzle, and other structures fixed to the second protective cover for disassembly. Meanwhile, the second protective cover further shields the outer surface of the first protective cover, preventing it from aging or being damaged by long-term exposure to water splashes, sunlight, or chemical substances. The third protective cover, as the outermost protective structure, is also detachably installed and covers the second protective cover to improve the overall appearance of the base station. In some embodiments, the outer surface of the third protective cover may be provided with anti-slip textures, water-guiding ribs, or curved structures to enhance user experience and environmental adaptability. In other embodiments, a flexible sealing ring or annular water-blocking plate may be configured between any two of the first, second, and third protective covers to improve sealing performance.

[0137] In some examples of this application, such as Figure 56 , Figure 57As shown, the support base 2171 also includes a fourth protective cover 21714 for protecting the second connecting pipe during base station transportation. The fourth protective cover 21714 includes a flat portion 217141, a protrusion 217142, and a receiving portion 217143. The protrusion 217142 is disposed on the upper surface of the flat portion 217141, and the receiving portion 217143 is disposed on the lower surface of the protrusion 217142 and extends through the flat portion 217141. In the installed state, the flat portion of the fourth protective cover is flush with the top of the base station body or at least partially protrudes from the top of the base station body. During base station transportation, the first nozzle and the first liquid inlet component need to be removed from the base station body to avoid damage during transportation. At this time, the second and third protective covers can be removed simultaneously with the first nozzle and the first liquid inlet component. Since the second connecting pipe 21785 and part of the clutch mechanism are exposed, the fourth protective cover can be placed on the first protective cover to prevent dust from falling in or structural damage during transportation. At this time, the top of the second connecting pipe 21785 extends into the receiving portion 217143 on the lower surface of the protrusion 217142. During base station installation, the fourth protective cover can be removed from the first protective cover, and then the second protective cover, the third protective cover, the first nozzle, and the first liquid inlet component can be simultaneously assembled onto the base station body.

[0138] In some embodiments, the fourth protective cover may be made of flexible or soft rubber material or elastic material, etc.

[0139] In some examples, such as Figures 35-40 As shown, the base station also includes a rotation limiting structure, which includes a limiting protrusion 217845 and a first limiting groove 217822. The limiting protrusion 217845 and the first limiting groove 217822 cooperate to limit the rotation path of the support arm 2172, so that the first nozzle 2173 switches between the retracted position and the extended position. In the example of this application, the limiting protrusion 217845 is disposed on the support arm 2172 or on a structure that moves synchronously with the support arm 2172, and the first limiting groove 217822 is disposed on the base station body 20001 or on a structure fixed relative to the base station body 20001. In a specific example of this application, the limiting protrusion 217845 is disposed on the first protrusion 217841 of the first connecting pipe 21784, and the first limiting groove 217822 is disposed on the bushing 21782. A first limiting protrusion 217823 and a second limiting protrusion 217824 are formed on opposite sides of the first limiting groove 217822 to limit the rotation range of the support arm 2172, so that the first nozzle 2173 switches between the retracted position and the extended position.

[0140] In some examples, such as Figure 7 , Figure 11 , Figure 20 , Figure 39 as well as Figures 43-48 As shown, the base station also includes a positioning detection mechanism 21789, which is disposed on the base station body or the second cleaning component. It is used to detect whether the first nozzle 2173 has reached the preset first position and second position, so as to feed back the position signal to the control unit of the base station and assist in achieving accurate docking of the first nozzle at the target cleaning position.

[0141] In some embodiments, the positioning detection mechanism 21789 includes at least two detection elements and at least one second mating element. The two detection elements are disposed on the base station body 20001 or on a structure fixed relative to the base station body 20001, respectively corresponding to the storage position (second position) and extension position (first position) of the first nozzle 2173. The second mating element is disposed on the support arm 2172 or on a structure that moves synchronously with the support arm 2172.

[0142] As a preferred example of this application, the detection element is at least one of a Hall sensor, a micro switch, a photoelectric sensor, a pressure sensor, a capacitive sensor, and an inductive sensor. The second mating element is adapted to the detection element; for example, when the detection element is a Hall sensor, the second mating element is a magnet; when the detection element is a micro switch, the second mating element is a pusher; when the detection element is a photoelectric sensor, the second mating element is a light-shielding element, etc. The position signal of the first nozzle is generated by the interaction between the detection element and the second mating element to determine whether the first nozzle is in the retracted or extended position.

[0143] In some examples, the positioning detection mechanism 21789 includes a first detection element 217891 and a second detection element 217892, as well as at least one second mating element 217893. One of the detection element and the second mating element 217893 is disposed on the first liquid inlet component 21801, and the other is disposed on the base station body 20001. When the first detection element 217891 detects the second mating element 217893, the first nozzle 2173 is in a first position. When the second detection element 217892 detects the second mating element 217893, the first nozzle 2173 is in a second position.

[0144] For example, in one specific embodiment, such as Figures 42-47 As shown, the first detection element 217891 and the second detection element 217892 are disposed on the motor base 21781 and / or the bushing. The first detection element 217891 is used to detect whether the first nozzle 2173 is in the retracted position or the extended position, and the second detection element 217892 is used to detect whether the first nozzle 2173 is in the extended position or the retracted position. The second mating part 217893 is disposed on the first connecting pipe 21784, and it cooperates with the first detection element 217891 and the second detection element 217892 to realize the position detection of the first nozzle 2173.

[0145] This application achieves high precision and high reliability in the position recognition of the first nozzle 2173 by arranging a positioning detection mechanism 21789 consisting of "dual detection components + synchronous cooperation components". The two detection components are used to detect whether the nozzle is in the retracted position or the extended position, forming a complete monitoring closed loop. This ensures that the first nozzle 2173 has a clear position signal output at any working stage, avoiding the problems of "false judgment of non-position" or "mid-position drift" that may occur in traditional single-point detection. The detection cooperation component set on the support arm 2172 moves synchronously with it, so that the detection behavior is always consistent with the actual position of the first nozzle 2173. Whether the first nozzle 2173 is driven by a motor or manually rotated by the user, the detection result can reflect the nozzle status in real time.

[0146] In one embodiment, such as Figures 39-41 As shown, both the first detection element 217891 and the second detection element 217892 are Hall sensors, which are set on the first limiting seat 217811 of the motor base 21781 and can be covered by the second limiting seat 217821 on the bushing 21782. The second mating part 217893 is a magnet, which can be set on the support arm or the first connecting tube. For example, the magnet is set on the first connecting tube 21784. Further, the magnet is set in the first mounting hole 217844 of the first boss 217841.

[0147] When the first filter cartridge needs cleaning, the first nozzle can be reset by turning on the drive motor to rotate it to the second position (retracted position). When the second detector 217892 detects a magnet, it indicates that the first nozzle 2173 is in the second position. Subsequently, the drive motor rotates the first nozzle from the second position to the first position (extended position). When the second detector 217892 does not detect a magnet, but the first detector 217891 detects a magnet, it indicates that the first nozzle 2173 is in the first position. The processor on the base station 2000 or the pool robot 1000 can control the first nozzle 2173 to start spraying liquid. After the first filter box is cleaned, the processor on the base station 2000 or the pool robot 1000 can control the first nozzle 2173 to stop spraying liquid. The drive motor causes the first nozzle to rotate from the first position to the second position. When the second detection element 217892 detects a magnet and the first detection element 217891 does not detect a magnet, it indicates that the first nozzle 2173 is in the storage position, and then the drive motor can be turned off.

[0148] In some embodiments, the first nozzle further has a third position located between the first and second positions, wherein the third position is a dynamically changing position. For example, the third position is an intermediate position between the first and second positions.

[0149] Therefore, in some embodiments, there are at least two second mating parts; wherein, the two second mating parts are distributed at intervals along the rotation direction of the first liquid inlet component; when the first detection element abuts against the second mating part, the second detection element separates from the other second mating part, and the first nozzle is in a first position; when the first detection element separates from the second mating part, and the second detection element separates from the other second mating part, the first nozzle is in a second position; when the first detection element abuts against the second mating part, and the second detection element abuts against the other second mating part, the first nozzle is in a third position.

[0150] In one specific embodiment, such as Figures 42-47 As shown, both the first detection element 217891 and the second detection element 217892 are microswitches. There are two second mating parts, namely the first sub-matting part 2178931 and the second sub-matting part 2178932. Both the first sub-matting part and the second sub-matting part are pushers. Furthermore, the first detection element and the second detection element are mounted on the motor base, and the pushers are mounted on the first connecting pipe 21784 and spaced apart along the rotation direction of the first connecting pipe. Furthermore, the pushers are mounted on the first boss.

[0151] like Figure 42 , Figure 43 As shown, when the first sub-mate does not trigger the first detection element and the second sub-mate does not trigger the second detection element, the first nozzle is in the second position, that is, the first nozzle is in the initial state; as Figure 46 , Figure 47 As shown, when the first sub-mate triggers the first detection element and the second sub-mate triggers the second detection element, the first nozzle is in the third position; as... Figure 44 , Figure 45 As shown, when the first sub-component triggers the first detection element and the second sub-component does not trigger the second detection element, the first nozzle is in the first position, that is, the first nozzle is in the working state.

[0152] To implement the above triggering logic, in one specific embodiment, such as Figure 42 , Figure 44 , Figure 46 As shown, the length of the first sub-mate is longer than the length of the second sub-mate, so that the first sub-mate can trigger the first detection element at both the first and third positions of the first nozzle, but the second sub-mate can only trigger the second detection element at the third position and cannot trigger the second detection element at the first position; or, in another embodiment, along the rotation direction of the first liquid inlet component, the distance between the first sub-mate at the second position and the first detection element is longer than the distance between the second sub-mate at the second position and the second detection element.

[0153] In the above embodiments, the positioning detection mechanism can identify the first position, second position and third position of the first nozzle to accurately know the working status of the first nozzle.

[0154] In some specific embodiments, such as Figure 5 , Figure 6 , Figure 7 As shown, a second delivery pipe 21793 is also provided on one side of the basic body. The second delivery pipe is connected to the first nozzle and is used to provide cleaning liquid to the first nozzle. For example, the second delivery pipe is connected to a second connecting pipe, and the connection method can be threaded, snap-fit, or plug-in. In some embodiments, the second connecting pipe can adopt a straight pipe, bent pipe, or flexible hose structure according to the internal layout of the base station.

[0155] In some specific embodiments, such as Figure 5 , Figure 6 As shown, a third delivery pipe 21794 is also provided on one side of the base station body. The third delivery pipe is detachably connected to the second delivery pipe. The end of the third delivery pipe away from the second delivery pipe extends out from one side or bottom of the base station body and is used to connect to a household faucet to supply cleaning liquid to the second delivery pipe. In some embodiments, the third delivery pipe serves as the inlet for external water supply and can be a rigid pipe, corrugated hose, etc. In some embodiments, the third delivery pipe is connected to the second delivery pipe through a quick-connect coupling, threaded coupling, or locking coupling to facilitate quick disassembly or replacement during transportation, installation, and subsequent maintenance.

[0156] In some embodiments, if there is a height difference or distance difference between the faucet and the base station, at least a fourth delivery pipe may be provided between the third delivery pipe and the household faucet to connect the third delivery pipe and the household faucet.

[0157] In some specific embodiments, such as Figure 3 As shown, a one-way valve 21792 is disposed between the second and third delivery pipes to control the flow of water, thereby controlling the flow of water from the first nozzle. For example, one end of the one-way valve is detachably connected to the second delivery pipe, and the other end is detachably connected to the third delivery pipe; furthermore, one end of the one-way valve is connected to the second delivery pipe via a connecting joint; the other end of the one-way valve is connected to the third delivery pipe via a connecting joint.

[0158] In some embodiments, such as Figure 3 As shown, a second mounting base 21795 is also provided on one side of the base station body, and a one-way valve 21792 (solenoid valve) is located in the second mounting base 21795.

[0159] In some embodiments, the second connecting pipe and the second conveying pipe are interference-fitted; furthermore, after the second connecting pipe and the second conveying pipe are connected, a cable tie is provided on the outside of the second connecting pipe to ensure a tight connection between the two. Specifically, as shown... Figure 19As shown, a second connecting part 217854 is provided at the lower end of the second connecting pipe, and the second connecting part 217854 is fixed to the upper end of the second conveying pipe by an interference fit or a sleeve connection.

[0160] In some embodiments, the second cleaning component can be configured as a detachable modular structure. For example, the second cleaning component can be integrated into a whole to form a modular structure, thereby realizing modular assembly. This allows the second cleaning component to be assembled into modules separately before being installed on the base station. This makes installation and disassembly convenient and easy to produce. At the same time, it also makes it easy to disassemble or replace parts during after-sales maintenance.

[0161] The detachable connection mentioned in this application is made by means of at least one of the following: threaded connection, magnetic connection, snap-fit ​​connection, key pin connection, locking connection, plug connection, grooved connection, screw connection, etc.
