Therefore, achieving efficient cleaning while reducing water consumption and optimizing wastewater management has become a pressing technical challenge. Summary of the Invention

[0003] In view of this, this application provides a cleaning base station for lawnmowers to solve the problems of excessive water consumption and waste caused by the existing lawnmower cleaning methods, as well as the increased environmental maintenance burden due to disorderly discharge of sewage.

[0004] The first aspect of this application provides a cleaning base station for lawnmowers, comprising: The base station body is located in the cleaning chamber used to accommodate the lawnmower; A cleaning device includes a rinsing component, a first water pump, and an automatic valve assembly.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Smart lawnmowers are a common sight in the daily lives of many users as a type of lawn maintenance equipment. After use, these machines often have dirt, grass clippings, and other debris stuck to their bottoms. Currently, users frequently use external water sprayers to remove this debris. However, directly using external water sprayers results in excessive water consumption and waste, and the resulting uncontrolled wastewater discharge also increases the burden on environmental maintenance. Therefore, achieving efficient cleaning while reducing water consumption and optimizing wastewater management has become a pressing technical challenge.

[0021] Based on this, see Figures 1 to 6 As shown, this embodiment of the invention provides a cleaning base station 10 for lawnmowers, which includes a base station body 100, a cleaning device 200, and a wastewater collection device 300. The base station body 100 is disposed in a cleaning chamber 110 for accommodating a lawnmower. The cleaning device 200 includes a flushing component, a first water pump 210, and an automatic valve assembly 220. The flushing component is disposed in the cleaning chamber 110, and the automatic valve assembly 220 is connected to the first water pump 210 and the flushing component, respectively. The automatic valve assembly 220 is used to control the connection or disconnection of the flushing component. The wastewater collection device 300 is connected to the cleaning chamber 110, and the input end of the first water pump 210 is connected to the wastewater collection device 300.

[0022] The base station body 100 serves as the basic support structure for the entire cleaning base station 10. Its material can be high-strength engineering plastics or metal alloys to ensure sufficient rigidity and corrosion resistance. The cleaning chamber 110 is formed inside or on top of the base station body 100, and its shape is adapted to the shape of the lawnmower to be cleaned, such as a rectangular or U-shaped trough, so that the lawnmower can be parked stably within it. The inner wall of the cleaning chamber 110 may be provided with anti-slip textures or positioning protrusions to limit the displacement of the lawnmower during the cleaning process.

[0023] The first water pump 210 is installed on an internal or external support of the base station body 100. Its inlet is connected to an external water source (such as a tap water network or a built-in clean water tank) via an inlet pipe, and its outlet is sealed to the inlet of the automatic valve assembly 220 via a pipe. The first water pump 210 can be a centrifugal pump or a diaphragm pump, and its rated head and flow rate are selected according to the size of the cleaning chamber 110 and the pressure requirements of the flushing components to provide a stable high-pressure water flow. The automatic valve assembly 220 is arranged in series in the flow channel between the first water pump 210 and the flushing components. Its valve body is fixed to the upstream and downstream pipes respectively by threaded connection, quick-connect fitting, or flange connection to ensure the sealing of the connection. The flushing components are fixedly installed on the inner wall, top, or bottom of the cleaning chamber 110, with their nozzles facing the surface of the lawnmower to be cleaned. When cleaning is required, the control system starts the first water pump 210 and opens the automatic valve assembly 220. The cleaning water is pressurized and flows through the automatic valve assembly 220 into the flushing unit, and is sprayed out from the nozzle to wash the lawnmower.

[0024] In the lawnmower cleaning base station 10 of this embodiment, since the input end of the first water pump 210 is connected to the sewage collection device 300, and the sewage collection device 300 is connected to the cleaning chamber 110, this structure allows the sewage collected in the sewage collection device 300 to be pumped by the first water pump 210 and transported to the rinsing component. By using the recycled sewage to rinse and clean the lawnmower located in the cleaning chamber 110, water resources are recycled, thereby reducing water consumption during the cleaning process of the smart lawnmower.

[0025] In the lawnmower cleaning base station 10 of this embodiment, an automatic valve assembly 220 is provided, which is connected to both the first water pump 210 and the flushing component. The automatic valve assembly 220 can adjust the connection or disconnection of the water path according to the control signal. This structure facilitates precise control of the start and stop of the flushing operation, avoids disordered discharge or continuous flow of water, helps optimize the wastewater management process, and further improves the orderliness of the cleaning process and the efficiency of resource utilization.

[0026] The automatic valve assembly 220 is designed for more precise and rapid water circuit control. Compared to traditional solutions, this assembly maintains a stable seal under high-pressure water flow, effectively preventing leaks caused by delayed valve closure or seal failure. This not only protects the electronic components inside the base station from moisture corrosion but also ensures accurate water volume control during each cleaning process, avoiding water waste. Simultaneously, the compact connection structure reduces the number of pipe interfaces, simplifies the assembly process, and improves production efficiency and product consistency.

[0027] The wastewater collection device 300 in this embodiment includes a collection tank 310 and a second water pump 320. The collection tank 310 is connected to the cleaning chamber 110, and the second water pump 320 is connected to the outlet of the collection tank 310. With this configuration, wastewater generated during the cleaning process can flow into the collection tank 310 through the cleaning chamber 110 for temporary storage, achieving centralized collection and management of wastewater and avoiding environmental pollution and odor generation caused by direct discharge of wastewater. Furthermore, the second water pump 320 can actively pump the wastewater out of the collection tank 310, eliminating the need for frequent manual emptying or cleaning of the collection container by the user, reducing the workload of later maintenance, and facilitating closed-loop management of the cleaning process and maintenance of environmental hygiene.

[0028] The collection tank 310 acts as a buffer and sedimentation unit, temporarily holding the mixed wastewater generated during cleaning and preventing it from overflowing or clogging the drainage pipes immediately. The active discharge function of the second water pump 320 breaks the limitations of traditional gravity drainage, allowing the base station to be installed in any location without relying on floor drains or specific drainage slopes. This proactive wastewater management mechanism significantly improves the user experience; users only need to empty the wastewater tank once when it is full, eliminating the need for manual intervention after each cleaning, truly achieving intelligent, unattended cleaning.

[0029] Specifically, the automatic valve assembly 220 includes a valve drive 221, a valve body 222, and a valve stem 223. The valve body 222 is connected to the first water pump 210 and the flushing component, respectively. The valve stem 223 is connected to the output end of the valve drive 221, and the valve drive 221 is used to drive the valve stem 223 to rotate so that the valve body 222 is connected or disconnected.

[0030] The valve actuator 221 serves as a power source, with its output shaft fixedly connected to one end of the valve stem 223. The connection method can be a key connection, pin connection, or interference fit to ensure effective torque transmission. The other end of the valve stem 223 extends into the flow channel inside the valve body 222 and is fixed with a valve core or sealing ball. The valve body 222 has inlet and outlet channels that are perpendicular or at a certain angle to each other. The rotation of the valve stem 223 causes the valve core to change position, thereby opening or closing these two channels. For example, when the valve stem 223 rotates 90 degrees, the through hole on the valve core aligns with the flow channel, allowing water to flow through; when the valve stem 223 rotates back to its original position, the solid part of the valve core blocks the flow channel, stopping the water flow. The valve actuator 221 can be a rotary actuator driven by a micro DC motor, stepper motor, or electromagnet. Using a stepper motor allows for precise angle control, facilitating flow rate adjustment; using an electromagnet results in a simple structure and low cost, suitable for scenarios requiring only full open or full close control. The valve body 222 should be made of materials with good water pressure resistance and corrosion resistance, such as brass, stainless steel or reinforced nylon.

[0031] In one embodiment, the automatic valve assembly 220 further includes a mounting base 224, which is detachably connected to the valve body 222, and the valve drive 221 is disposed on the mounting base 224.

[0032] Mounting base 224 serves to support and position valve actuator 221, and its structure matches that of valve body 222. Mounting base 224 can be fixed to the outer wall of valve body 222 by screws, snap-fit ​​locking, or threaded engagement. This detachable connection design makes valve actuator 221 an independent module, facilitating individual testing, maintenance, or replacement. For example, when valve actuator 221 malfunctions, technicians can simply loosen the connection between mounting base 224 and valve body 222 to remove the entire actuator module without disassembling complex water pipes, significantly reducing maintenance difficulty and time costs. Furthermore, mounting base 224 can be internally fitted with bearings or bushings to support valve stem 223, reducing frictional resistance and radial runout during valve stem rotation, thereby improving valve smoothness and sealing surface fit accuracy. Mounting base 224 can also integrate a waterproof sealing ring to prevent moisture from seeping into valve actuator 221 along valve stem 223, extending the service life of electrical components.

[0033] Furthermore, the rinsing component includes a first rinsing component 240 and a second rinsing component 250, which are respectively connected to the automatic valve assembly 220. The first rinsing component 240 and the second rinsing component 250 are spaced apart in the cleaning chamber 110. The first rinsing component 240 and the second rinsing component 250 are used to spray water toward the lawnmower.

[0034] The first flushing component 240 and the second flushing component 250 form a three-dimensional flushing network distributed internally and externally or vertically. The first flushing component 240 mainly covers the outer area of ​​the lawnmower and the edge of the chassis, while the second flushing component 250 focuses on cleaning the central area or upper surface of the machine. The spacing between the two avoids interference between water flows, ensuring targeted cleaning of different parts of the lawnmower, improving cleaning efficiency and coverage.

[0035] In one embodiment, a first rinsing member 240 is disposed around the edge of the cleaning chamber 110, and a second rinsing member 250 is rotatably connected to the base station body 100 and located inside the first rinsing member 240.

[0036] The first rinsing component 240 is arranged circumferentially along the cleaning chamber 110, forming a ring-shaped spray structure that can converge water flow from all sides to the center, effectively removing dirt adhering to the lawnmower's side brushes, chassis edges, and the outer sides of the travel wheels. The second rinsing component 250 is located at the inner center of the ring structure. Its rotating connection allows it to perform rotary scanning cleaning during operation, compensating for any blind spots that may exist with the fixed nozzle. It is particularly suitable for cleaning precision components such as sensors and charging contacts on the top of the lawnmower.

[0037] Furthermore, the first flushing component 240 is provided with a plurality of first water outlets, which are spaced apart along the first flushing component 240.

[0038] Multiple first water outlets are evenly distributed on the pipe wall or nozzle seat of the first flushing component 240. The spacing can be optimized according to the size of the cleaning chamber 110 and the water pressure requirements, for example, one water outlet can be set at a preset distance. This discrete distribution method can form a dense water curtain, ensuring the continuity of water flow coverage and avoiding cleaning dead zones.

[0039] In one embodiment, at least a portion of the first water outlet is oriented at an angle to the central axis of the travel wheel so that the first water outlet can wash the tire surface of the travel wheel, and the other portion of the first water outlet is oriented towards the side of the travel wheel so as to wash the outer side of the wheel hub of the travel wheel.

[0040] For the driving wheels, a critical area prone to mud accumulation, the first water outlet features a multi-angle directional design. The outlet facing the tire tread sprays at a certain angle (e.g., 30°-60°), using the impact of the water flow to remove stones and large pieces of mud deep within the tire treads. The outlet facing the wheel hub sprays horizontally or slightly downwards, washing away grass clippings and mud from the wheel hub crevices. This combined washing strategy effectively solves the problem of wheel cleaning, preventing mud buildup from affecting the lawnmower's walking accuracy and motor lifespan.

[0041] In one embodiment, the second flushing member 250 is provided with a plurality of second water outlets, which are arranged at an angle to the rotation axis of the second flushing member 250.

[0042] The axis of the second water outlet is not parallel to the rotation center line of the second flushing component 250, but rather forms a certain tilt angle (e.g., 30°, 45°). When high-pressure water is ejected from these tilted outlets, a tangential reaction force component is generated. This reaction force forms a torque, driving the second flushing component 250 to rotate automatically around its axis. This self-driving mechanism eliminates the need for an additional motor or transmission mechanism, simplifying the structural design, reducing energy consumption and noise, while the dynamic water flow generated by the rotation has a stronger agitation capability, helping to loosen and remove stubborn stains.

[0043] The second flushing component 250 is rotatably connected to the base station body 100. By providing multiple second water outlets, the second flushing component 250 can be driven to rotate under the reaction force of the water flow. Specifically, the second flushing component 250 is mounted on the bracket of the base station body 100 via bearings, bushings, or pivot structures, ensuring its stability and coaxiality during rotation. Changes in water pressure can directly adjust the rotation speed; higher water pressure results in faster rotation and stronger cleaning force. This passive rotational design is not only reliable and durable but also adaptively adjusts its working state according to the water supply pressure, improving the system's reliability.

[0044] To ensure smooth rotation of the second flushing component 250, a grease-lubricated bushing or a self-lubricating material can be used at the rotating connection between it and the base station body 100. The support structure should have sufficient rigidity to resist vibrations caused by the reaction force of the water flow. Furthermore, a rotary joint can be installed at the water inlet end of the second flushing component 250 to ensure that the water supply pipeline does not become entangled or twisted during rotation. By adjusting the output power of the first water pump 210, the rotational speed of the second flushing component 250 can be indirectly controlled, thereby achieving graded adjustment of cleaning intensity to meet the cleaning needs of different levels of dirt.

[0045] Furthermore, the cleaning device 200 also includes a diversion component 230, which includes an inlet 231, a first outlet 232, and a second outlet 233 connected together. The inlet 231 is connected to the first water pump 210, the first outlet 232 is connected to the first flushing component 240, and the second outlet 233 is connected to the second flushing component 250. There are two sets of automatic valve assemblies 220, and the two sets of automatic valve assemblies 220 are respectively connected to the first outlet 232 and the second outlet 233.

[0046] As the core component for water distribution, the diverter 230's internal flow channel design should ensure uniform water distribution or proportional distribution as needed. The inlet 231 receives high-pressure water from the first pump 210 and diverts it to the first outlet 232 and the second outlet 233. Two sets of automatic valve assemblies 220 are installed downstream of the first outlet 232 and the second outlet 233, respectively, independently controlling the flow of water to the first flushing element 240 and the second flushing element 250. This dual-valve independent control architecture supports multiple cleaning modes: for example, opening only the valve connected to the first flushing element 240 for powerful chassis flushing; opening only the valve connected to the second flushing element 250 for gentle body cleaning; or opening both sets of valves simultaneously for comprehensive deep cleaning. Independent control not only improves cleaning flexibility but also helps save water resources and avoid unnecessary energy consumption. The diverter 230 can be integrally cast or injection molded to reduce leakage points and improve structural strength.

[0047] In one embodiment, the sewage collection device 300 further includes a first filter screen 330, which is disposed in the collection tank 310 and divides the internal space of the collection tank 310 into a first cavity 311 and a second cavity 312. The first cavity 311 is connected to the cleaning chamber 110, and the second cavity 312 is located at the bottom of the first cavity 311 and is connected to the second water pump 320.

[0048] The first filter screen 330, as a key component in solid-liquid separation, has a rationally designed mesh size that effectively intercepts large particles of grass clippings, mud clods, and other debris mixed in with the wastewater. The first chamber 311, serving as the primary sedimentation and filtration zone, receives high-concentration wastewater from the washing chamber 110, where larger impurities are trapped and deposited. The filtered water flows through the first filter screen 330 into the second chamber 312 located at the bottom. Because the second chamber 312 is lower in position and contains fewer impurities, the impeller of the second pump 320 is less prone to jamming or wear when drawing wastewater from here, thus ensuring the long-term stable operation of the sewage system. Furthermore, this stratified design helps to mitigate water flow impact, allowing some fine sediment to settle naturally in the first chamber 311, further reducing the solid content entering the pump.

[0049] Specifically, the sewage collection device 300 also includes a sewage tank 340, which is located on the base station body 100. The second water pump 320 is connected to the sewage tank 340 and the second cavity 312 respectively, and the first water pump 210 is connected to the sewage tank 340.

[0050] Wastewater tank 340, as the final wastewater storage container, typically has a large volume to reduce the frequency of user cleaning. The second water pump 320 pumps wastewater from the second chamber 312 of the collection tank 310 to the wastewater tank 340 for centralized storage. The wastewater tank 340 can be designed as a detachable structure for easy removal and cleaning by the user; or it can be equipped with a transparent observation window for easy visual assessment of the wastewater level. By separating the temporary storage (collection tank 310) from the final collection (wastewater tank 340), the risk of direct overflow due to fluctuations in water volume during a single cleaning cycle can be avoided, improving the system's fault tolerance.

[0051] In one embodiment, the inlet 231 is connected to the output end of the sewage tank 340 through the flushing inlet pipe 211, and the first water pump 210 is installed on the flushing inlet pipe 211. The first outlet 232 is connected to the first flushing component 240 through the first flushing pipe 212, and the second outlet 233 is connected to the second flushing component 250 through the second flushing pipe 213.

[0052] This pipeline layout establishes a complete fluid transport path from sewage storage to final flushing. The flushing input pipe 211 serves as the main water supply trunk, connecting the sewage tank 340 to the branch pipe 230. The first water pump 210 is connected in series on this pipe, providing the power source for the circulating water. The first flushing pipe 212 and the second flushing pipe 213 serve as branch pipes, precisely delivering the diverted water flow to the corresponding first flushing component 240 and second flushing component 250. This zoned pipeline design not only clarifies the connection relationships between each functional module but also facilitates independent pressure testing and sealing checks during assembly. The pipes can be made of flexible corrosion-resistant hoses or rigid engineering plastic pipes, securely connected to each interface using clamps or quick-connect fittings to ensure they do not detach or leak under high-pressure water pressure.

[0053] Specifically, the wastewater tank 340 is used to store and collect the wastewater output from the water tank 310 (which can be pumped by the second water pump 320). When the lawnmower needs to be cleaned using the flushing component, the automatic valve assembly 220 is opened and the first water pump 210 is started, so that the water in the wastewater tank 340 enters the inlet 231 of the diverter 230 through the flushing inlet pipe 211. After passing through the diverter 230, the water is diverted and transported to the first flushing component 240 through the first outlet 232 along the first flushing pipe 212, and to the second flushing component 250 through the second outlet 233 along the second flushing pipe 213.

[0054] This process achieves automated wastewater recycling. During the cleaning phase, the control system first confirms that the automatic valve assembly 220 is open, then starts the first water pump 210. Water from the wastewater tank 340 is drawn into the flushing input pipe 211 under negative pressure, and after being pressurized by the first water pump 210, it enters the diversion component 230. The diversion component 230, based on its internal flow channel structure, distributes the water flow to two branches, which are then sprayed out by the first flushing component 240 and the second flushing component 250 to perform the cleaning task. This process has a clear logic, and the actions of each component are coordinated and orderly, ensuring the continuity and stability of the cleaning operation. By controlling the speed of the first water pump 210, the water pressure entering the diversion component 230 can also be adjusted to meet the cleaning needs of different levels of dirt.

[0055] Furthermore, the sewage collection device 300 also includes a second filter screen 360, which is located inside the sewage tank 340, and the first water pump 210 is located downstream of the second filter screen 360.

[0056] The placement of the second filter screen 360, as a fine filtration element in the circulating water system, is crucial. Positioned within the wastewater tank 340 and upstream of the first water pump 210, it ensures that all water entering the circulating pump must first pass through this filter. This arrangement effectively prevents fine particles, fibers, or sediments remaining in the wastewater from entering the first water pump 210, avoiding impeller wear, jamming, or seal failure. Simultaneously, it protects downstream pipes and flushing nozzles from clogging, maintaining the stability and uniformity of the jet flow. The mesh size of the second filter screen 360 is typically smaller than that of the first filter screen 330, achieving a deeper purification effect. Water treated by the second filter screen 360 exhibits a significantly reduced suspended solids content, meeting the water quality standards for circulating flushing. This not only improves the cleaning effect and prevents secondary pollution but also extends the service life of the entire water system. Regular cleaning or replacement of the second filter screen 360 maintains the system's efficient operation; maintenance is simple, reducing user costs.

[0057] In one embodiment, the sewage collection device 300 further includes a sewage input pipe 370, one end of which is connected to the output end of the collection tank 310, the sewage input pipe 370 is installed inside the sewage tank 340, and the other end of the sewage input pipe 370 is located upstream of the second filter screen 360. The second water pump 320 is installed on the sewage input pipe 370.

[0058] Wastewater inlet pipe 370 forms a transfer channel from primary collection to final storage. A second water pump 320 is installed on this pipe, providing active power for wastewater discharge. The design of the pipe running inside the wastewater tank 340 utilizes the tank space, reducing exposed external pipes and making the base station look cleaner and more aesthetically pleasing. Furthermore, the internal pipes are protected by the tank, making them less susceptible to external environmental influences or physical damage. The pipe outlet is located upstream of the second filter screen 360, ensuring that wastewater entering the wastewater tank 340 has the opportunity to have impurities removed through gravity settling or filter interception before settling or being pumped for circulation.

[0059] In this embodiment, the water output from the collection tank 310 is pumped by the second water pump 320 and enters the sewage tank 340 for storage via the sewage inlet channel 370. By placing the output end of the sewage inlet channel 370 upstream of the second filter screen 360, it can be ensured that the water output from the sewage inlet channel 370 is filtered by the second filter screen 360 before being pumped for cleaning by the first water pump 210. Therefore, regardless of whether the sewage enters the sewage tank 340 by natural flow or pumping, it must pass through the second filter screen 360 before being re-extracted by the first water pump 210. This forms a dual protection mechanism: the first line of defense is the first filter screen 330 in the collection tank 310, and the second line of defense is the second filter screen 360 in the sewage tank 340. The two-stage filtration works in series, removing impurities of different particle sizes step by step, maximizing the cleanliness of the recycled water, thereby improving the reliability and durability of the overall cleaning system.

[0060] By embedding the sewage inlet pipe 370 within the sewage tank 340, this built-in piping layout optimizes the space utilization inside the base station, eliminates the extra volume occupied by external connecting pipes, and facilitates the miniaturization of the base station design. Simultaneously, this integrated structure reduces pipe connection points in the assembly process, lowers the risk of leakage during production, and improves product consistency and yield. For users, the simple external structure also facilitates daily cleaning and maintenance, enhancing the overall quality of the product.

[0061] In one embodiment, the sewage collection device 300 further includes a sewage valve 350, which is connected to the second water pump 320 and the sewage tank 340.

[0062] A sewage valve 350 is located between the outlet of the second water pump 320 and the inlet of the sewage tank 340 to control the opening and closing of the sewage discharge passage. When the second water pump 320 stops working, the sewage valve 350 is in the closed state. This not only prevents sewage in the sewage tank 340 from flowing back into the collection tank 310 or the cleaning chamber 110, but also effectively blocks the diffusion of odors generated in the sewage tank 340, maintaining a fresh air environment around the base station. The sewage valve 350 can be a one-way check valve or a solenoid control valve to ensure good sealing performance while stopping the pump immediately.

[0063] Furthermore, the sewage collection device 300 also includes a liquid level sensor, which is located inside the sewage tank 340 and is connected to the second water pump 320.

[0064] A liquid level sensor monitors the water level in the sewage tank 340 in real time and feeds the signal back to the main control unit of the base station. When the water level in the sewage tank 340 reaches the preset high-level warning line, the main control unit controls the second water pump 320 to stop working and issues a full-tank alarm (such as an audible and visual alarm or a push notification on a mobile app), reminding the user to clean the sewage tank 340 in time to prevent sewage from overflowing and polluting the ground. When the user has finished cleaning and the water level has dropped below the low-level safety line, the system is unlocked, allowing the second water pump 320 to restart for sewage discharge. This intelligent feedback mechanism realizes fully automated management of the sewage collection process, avoiding equipment failures or environmental sanitation problems caused by human negligence.
