Description

Technical Field

[0001] This application relates to the field of lawn mowing equipment technology, and more particularly to a cleaning base station for lawn mowers. Background Technology

[0002] Automatic cleaning stations for lawnmowers are typically equipped with a cleaning system and wastewater collection structure to wash away grass clippings and dirt adhering to the bottom of the lawnmower when it is recharged, and to collect and treat the resulting mixed wastewater to maintain the cleanliness of the equipment's interior and surrounding environment.

[0003] Existing wastewater collection solutions often employ fixed collection trays or designs integrated with the base. Because wastewater contains a large amount of fibrous grass clippings and silt, scale easily accumulates at the bottom of the container after long-term operation. This fixed structure necessitates disassembling the external cover or using tools to access the interior for cleaning and maintenance, a cumbersome process that makes it difficult to thoroughly clean hard-to-reach areas. Furthermore, fixed collection structures cannot achieve quick separation, making it inconvenient for users to empty wastewater and clean the container, impacting the efficiency and convenience of daily maintenance. Therefore, existing solutions still fall short in balancing wastewater collection functionality with ease of maintenance. Summary of the Invention

[0004] In view of this, this application provides a cleaning base station for lawnmowers to solve the problem of inconvenient maintenance caused by the fixed or integrated structure of traditional lawnmower base station wastewater collection.

[0005] The first aspect of this application provides a cleaning base station for lawnmowers, comprising: The chassis structure has an internal receiving cavity, and the chassis structure has a cleaning cavity and a drain hole. The cleaning cavity is used to receive the lawnmower, and the drain hole is connected to the cleaning cavity and the receiving cavity respectively. A water collection box is movably connected to the chassis structure, and the water collection box is provided with a water collection cavity, which is connected to the drain hole and used to collect sewage; and A cleaning device is provided within the chassis structure, and the cleaning device is used to clean the lawnmower.

[0006] In one possible implementation, the water collection box is provided with a drain outlet that is connected to the water collection chamber and used to discharge sewage.

[0007] In one possible implementation, the bottom of the water collection cavity is provided with an inclined guide surface, the bottom of which faces the drain outlet.

[0008] In one possible implementation, the water collection box includes a box body and a flow guide, the water collection cavity is disposed in the box body, the flow guide is disposed at the bottom of the water collection cavity, and the extension direction of the flow guide is toward the drain outlet.

[0009] In one possible implementation, there are multiple flow guides, which are spaced apart within the water collection cavity, and at least two adjacent flow guides are spaced apart to form a flow channel, the cross-section of which gradually decreases along the path toward the drain outlet.

[0010] In one possible implementation, the drain outlet includes a first drain outlet and a second drain outlet, the first drain outlet and the second drain outlet being spaced apart, and the bottom of the first drain outlet being lower than the bottom of the second drain outlet.

[0011] In one possible implementation, the water collection box is provided with a pull-out portion located at the opening of the water collection box facing the receiving cavity; And / or, the water collection box is provided with a support portion, which is located at the bottom of the water collection box.

[0012] In one possible implementation, the chassis structure includes a cleaning chamber and a bottom plate, the bottom plate being detachably connected to the cleaning chamber and enclosing the cleaning chamber to form the receiving cavity, the cleaning cavity being located at the top of the cleaning chamber, and the drain hole being located through the bottom of the cleaning chamber.

[0013] In one possible implementation, the base plate is provided with a support portion that protrudes from the bottom of the receiving cavity and is used to support the water collection box; And / or, the base plate is provided with a guide surface, the guide surface is set at an angle to the opening direction of the receiving cavity, and the guide surface is used to guide the water collection box into the receiving cavity.

[0015] Implementing the embodiments of this application has the following beneficial effects: In this embodiment of the lawnmower cleaning base station, the water collection box and the chassis structure are movably connected. Since the water collection box has a water collection chamber that communicates with the cleaning chamber through a drain hole, wastewater generated during lawnmower cleaning can flow into the water collection chamber for collection via the drain hole. When it is necessary to clean the wastewater or remove deposits, the user can directly remove the water collection box from the chassis structure without disassembling other parts of the chassis structure or using tools to access the interior. This structural design simplifies the steps of removing and placing the wastewater collection container, improving the convenience of daily maintenance.

[0016] Furthermore, the movable water collection box, acting as an independent wastewater collection unit, can be directly emptied and rinsed after removal, avoiding the incomplete cleaning problems caused by hard-to-reach corners in fixed structures.

[0020] 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.

[0021] Automatic cleaning stations for lawnmowers are typically equipped with a cleaning system and wastewater collection structure to wash away grass clippings and dirt adhering to the bottom of the lawnmower when it is recharged, and to collect and treat the resulting mixed wastewater to maintain the cleanliness of the equipment's interior and surrounding environment.

[0022] Existing wastewater collection solutions often employ fixed collection trays or designs integrated with the base. Because wastewater contains a large amount of fibrous grass clippings and silt, scale easily accumulates at the bottom of the container after long-term operation. This fixed structure necessitates disassembling the external cover or using tools to access the interior for cleaning and maintenance, a cumbersome process that makes it difficult to thoroughly clean hard-to-reach areas. Furthermore, fixed collection structures cannot achieve quick separation, making it inconvenient for users to empty wastewater and clean the container, impacting the efficiency and convenience of daily maintenance. Therefore, existing solutions still fall short in balancing wastewater collection functionality with ease of maintenance.

[0023] Based on this, see Figures 1 to 4 As shown, this embodiment of the invention provides a cleaning base station 10 for lawnmowers, which includes a chassis structure 100, a water collection box 200, and a cleaning device 300. The chassis structure 100 has a receiving cavity 111 inside, and the chassis structure 100 has a cleaning cavity 112 and a drain hole 113. The cleaning cavity 112 is used to receive the lawnmower, and the drain hole 113 is connected to the cleaning cavity 112 and the receiving cavity 111 respectively. The water collection box 200 is movably connected to the chassis structure 100, and the water collection box 200 has a water collection cavity 211, which is connected to the drain hole 113 and is used to collect sewage. The cleaning device 300 is disposed inside the chassis structure 100 and is used to clean the lawnmower.

[0024] The chassis structure 100, serving as the main support frame of the base station, can be injection molded from engineering plastics or bent and welded from metal sheets. Its internal cavity 111 provides installation space for other functional modules. The cleaning cavity 112 is located on the upper surface or side of the chassis structure 100, its outline conforming to the bottom shape of the lawnmower to be cleaned, and can be surrounded by a water-retaining edge to prevent splashing of cleaning water. The drain hole 113 serves as a fluid channel, its diameter adjustable according to the maximum particle size of impurities in the wastewater, for example, between 10mm and 50mm, to ensure smooth passage of grass clippings without clogging. The drain hole 113 vertically penetrates the bottom plate of the chassis structure 100, connecting the upper cleaning cavity 112 with the lower cavity 111. The water collection box 200, as an independent modular component, has a water collection chamber 211 with a volume greater than the maximum wastewater volume generated in a single cleaning operation, and can be equipped with a level sensor to monitor full load status. The "movable connection" between the water collection box 200 and the chassis structure 100 can be specifically manifested in various ways such as sliding rail engagement, snap locking, magnetic positioning, or hinge flipping, aiming to achieve a detachable sealed connection between the two.

[0025] In the lawnmower cleaning base station 10 of this embodiment, the water collection box 200 and the chassis structure 100 are connected in a movable manner. This movable connection can be implemented in several ways: a guide rail is provided at the opening of the receiving cavity 111 of the chassis structure 100, and a corresponding slider is provided on the outer wall of the water collection box 200; the two are slidably engaged to achieve pull-out installation. Alternatively, an elastic buckle is provided on the edge of the water collection box 200, which is press-fitted with a slot on the chassis structure 100, allowing for quick disassembly and assembly by pressing to unlock. Another option is to utilize magnetic components, with opposite magnetic poles provided on the contact surfaces of the water collection box 200 and the chassis structure 100, using magnetic attraction to maintain a stable position while allowing manual separation by applying external force. Regardless of the specific connection method used, when the water collection box 200 is installed in place, the inlet end of its water collection cavity 211 can form a tight fluid seal with the outlet end of the drain hole 113, preventing sewage leakage to other areas of the receiving cavity 111. Because the water collection box 200 has a water collection chamber 211 that is connected to the cleaning chamber 112 via a drain hole 113, wastewater generated from cleaning the lawnmower can flow into the water collection chamber 211 for collection through the drain hole 113. When it is necessary to clean the wastewater or remove deposits, the user can directly remove the water collection box 200 from the chassis structure 100 without disassembling other parts of the chassis structure 100 or using tools to access the interior. This structural design simplifies the steps of removing and placing the wastewater collection container, which helps to improve the convenience of daily maintenance.

[0026] Furthermore, the movable water collection box 200 serves as an independent wastewater collection unit, allowing for direct emptying and rinsing after removal, thus avoiding the incomplete cleaning problems caused by hard-to-reach corners in fixed structures. This design makes wastewater collection and maintenance processes independent, improving the cumbersome cleaning of existing fixed water collection trays, helping to maintain the hygiene inside the base station and extend the service life of the equipment.

[0027] During operation, the lawnmower enters and positions itself in the cleaning chamber 112. The cleaning device 300 activates and sprays cleaning fluid onto the bottom of the lawnmower. The mud and water mixture washed down collects at the bottom of the cleaning chamber 112 under gravity, then flows through the drain hole 113 and either falls directly into or is guided into the water collection chamber 211 of the water collection box 200 below. During this process, the interface between the drain hole 113 and the water collection chamber 211 can be designed as a funnel-shaped flared structure to increase the water collection area, reduce the requirements for installation accuracy, and ensure that even with slight positional deviations, the wastewater can accurately fall into the water collection chamber 211. Specifically, the user only needs to perform a single unlocking action (such as pulling the handle to release the latch, pulling the slider outward, or overcoming magnetic attraction to lift the box) to remove the entire water collection box 200, along with the accumulated wastewater and sediment, from the base station body. This process completely avoids the cumbersome steps of disassembling the casing and digging with tools required in traditional solutions, simplifying a complex maintenance task that might take several minutes into a simple operation of a few seconds, significantly reducing the user's operational threshold and time cost. By designing the easily soiled collection components as independent detachable modules, the design concept of "dirty and clean separation" is realized, so that maintenance actions are no longer limited by the fixed structure of the base station, thereby effectively improving the user experience of the product.

[0028] Once the water collection box 200 is removed, the user can move it directly over a sink, toilet, or outdoor drain, and tilt the box to empty the liquid wastewater and suspended impurities inside in one go. Subsequently, since the water collection chamber 211 is completely exposed and unobstructed, the user can directly rinse the inner wall with a faucet or easily scrub the bottom and corners of the chamber with a brush to thoroughly remove attached fibrous grass clippings and hardened silt, ensuring the container's interior is restored to a clean state. In contrast, fixed structures often have blind spots and deep corners that tools cannot reach, while the independent box design of this embodiment eliminates these physical obstacles, allowing cleaning operations to achieve the same thoroughness as cleaning ordinary household containers. Because the water collection box 200 can be cleaned frequently and thoroughly, it avoids the foul odors produced by the long-term accumulation and fermentation of dirt, which can corrode internal electronic components or seals. It also prevents the risk of sewage overflow caused by heavy dirt clogging the drainage path. This ease of maintenance encourages users to perform regular cleaning and maintenance, thereby ensuring the long-term stability and reliability of the cleaning base station 10 from the source and extending the overall operating cycle of the unit.

[0029] In one embodiment, the drain hole 113 may be a rectangular structure to increase the drainage capacity.

[0030] Specifically, the rectangular drainage hole 113 is located in the bottom connecting area of ​​the chassis structure 100. Its short side extends along the main path of sewage flow, while its long side is perpendicular to the flow direction. Compared to traditional circular holes, the rectangular cross-section provides a larger effective flow area under the same maximum profile size constraint, thereby significantly reducing the resistance coefficient when the fluid passes through. When the cleaning device 300 generates a large amount of instantaneous flushing water, the wide rectangular opening can quickly receive and guide mixed sewage containing large pieces of grass clippings, leaf fragments, and clumps of soil, effectively avoiding turbulent accumulation caused by excessive local flow velocity or blockage caused by limited orifice diameter. In addition, the right-angled or rounded edge design of the rectangular structure facilitates alignment and matching with the corresponding rectangular water inlet on the water collection box 200, forming a line seal or surface seal connection, further improving the reliability of the drainage connection. This choice of geometry not only helps to increase the sewage discharge capacity per unit time but also reduces the probability of dirt accumulating at the edge of the orifice, ensuring the continuity and smoothness of the cleaning process.

[0031] In one embodiment, the water collection box 200 is provided with a drain outlet, which is connected to the water collection chamber 211 and used to discharge sewage.

[0032] The drain outlet is typically located at the lowest point of the side wall or bottom wall of the water collection box 200. Its orifice size can be designed to match the flow parameters of the sewage pump or the flow velocity requirements of gravity discharge. The drain outlet can optionally be equipped with a sealing cap, a one-way valve, or a quick-connect fitting. When the water collection box 200 is installed within the chassis structure 100, the drain outlet can automatically connect to the sewage pipes inside the base station to achieve automatic sewage extraction. When the water collection box 200 is removed for independent use, the user can open the sealing cap or connect a hose to directly discharge sewage into the sewer. This dual-discharge design meets the unattended operation requirements of fully automatic operation while retaining the flexibility and convenience for manual intervention, ensuring efficient sewage discharge operations in different usage scenarios.

[0033] Furthermore, the bottom of the water collection cavity 211 is provided with an inclined guide surface 212, with the bottom of the guide surface 212 facing the drain outlet. This guide surface 212 can be an inclined surface integrally formed on the inner wall of the box body 210, or it can be a partially inclined structure formed by an additional guide plate. The inclined direction of the partially inclined structure is set towards the central axis of the drain outlet, using the component of gravity to cause the sewage and suspended impurities deposited at the bottom of the cavity to converge towards the lower area. By eliminating the horizontal stagnation area at the bottom, the guide surface 212 effectively prevents sewage from accumulating in corners, ensuring that the liquid in the water collection cavity 211 can be completely drained, reducing the risk of residual sewage breeding bacteria or producing odors.

[0034] See Figure 4 As shown, the angle between the guide surface 212 and the horizontal is R. The value range of this angle R has been verified by fluid dynamics simulation and experiments, and it is preferably set between 5° and 45°, more preferably between 10° and 30°. If the angle R is less than 5°, the component of gravity along the slope is too small, which may cause viscous mud or long-fiber grass clippings to crawl slowly or even stop on the slope, resulting in poor drainage. If the angle R is greater than 45°, although the flow rate is extremely fast, it will excessively compress the effective volume of the water collection chamber 211, resulting in a significant decrease in the water storage capacity of the water collection box 200 under the same external dimensions, increasing the frequency of users dumping sewage. Therefore, selecting a moderate angle R can achieve the best balance between ensuring rapid drainage and maintaining a large effective volume, which helps to improve sewage discharge efficiency and extend the service life of a single maintenance.

[0035] In one embodiment, the water collection box 200 includes a box body 210 and a flow guide 220. The water collection cavity 211 is disposed inside the box body 210, and the flow guide 220 is disposed at the bottom of the water collection cavity 211, with the extension direction of the flow guide 220 facing the drain outlet.

[0036] The housing 210, serving as the primary load-bearing container, can be made of corrosion-resistant and impact-resistant polymer materials. The flow guide 220, acting as a functional enhancement component, can be an integrally injection-molded rib or boss, or a separately bonded or snap-fitted flow guide plate. The flow guide 220 extends from the distal end of the water collection chamber 211 towards the drain outlet. Its smooth surface and slope guide the fluid along a predetermined path. For wastewater containing a large amount of solid particles, the flow guide 220 also acts as a sorting agent, preventing large impurities from laterally accumulating and clogging the flow channel, ensuring smooth flow of wastewater to the drain outlet. The flow guide 220 facilitates the guidance of wastewater to the drain outlet, especially in conditions where the wastewater has high viscosity or contains a large amount of fibrous material. The directional guidance provided by the flow guide 220 overcomes the viscous resistance within the fluid, accelerating the collection process of wastewater towards the discharge point, thereby shortening the emptying time and improving the turnaround efficiency of the base station.

[0037] Furthermore, there are multiple guide sections 220, which are spaced apart in the water collection cavity 211, and at least two adjacent guide sections 220 are spaced apart to form a guide channel, the cross-section of which gradually decreases on the path toward the drain outlet.

[0038] These parallel or radially arranged guide sections 220 divide the bottom space of the collection chamber 211 into several independent or interconnected guide channels. As the fluid flows towards the drain outlet, the distance between adjacent guide sections 220 gradually decreases, causing the cross-sectional area of ​​the guide channels to contract in a stepped or continuous manner. According to the fluid continuity equation, under constant flow conditions, the reduction in channel cross-sectional area will lead to an increase in fluid velocity. This structure helps to carry more sediment towards the drain outlet at high speed, preventing impurities from settling during flow. At the same time, the gradually narrowing channel structure can also squeeze and break up large debris, making it easier for them to pass through the drain outlet, further reducing the risk of blockage. Setting multiple guide sections 220 can form at least one guide channel to improve flow efficiency. The multi-channel design also provides redundancy backup. Even if one channel is temporarily blocked by individual large foreign objects, the other channels can remain unobstructed, ensuring that the sewage discharge system does not completely fail, significantly improving the system's reliability and fault tolerance.

[0039] In one embodiment, two guide sections 220 are symmetrically arranged to form a conical guide channel. This symmetrical layout typically centers on the drain outlet, with the two guide sections 220 converging inward in a "V" or funnel shape. The conical structure has excellent spatial convergence characteristics, enabling it to uniformly collect sewage from all directions of the collection chamber 211 and guide it to the central drain outlet, eliminating dead zones in the flow. Furthermore, the symmetrical conical channel is more evenly stressed, able to withstand fluid impacts from all directions without easily deforming, and its smooth converging surface helps reduce fluid friction resistance, allowing sewage to naturally and rapidly slide down under gravity, achieving a highly efficient and residue-free sewage discharge effect.

[0040] In one embodiment, the drain outlet includes a first drain outlet 213 and a second drain outlet 214, the first drain outlet 213 and the second drain outlet 214 are spaced apart, and the bottom of the first drain outlet 213 is lower than the bottom of the second drain outlet 214.

[0041] This staggered dual-outlet design constitutes a graded discharge mechanism. The first outlet 213, located at the lowest point, serves as the main discharge outlet, responsible for discharging the majority of wastewater and sediment at normal liquid levels. The second outlet 214, positioned relatively higher, can serve as an overflow outlet or auxiliary discharge outlet. When wastewater is generated extremely rapidly and the liquid level quickly rises beyond the discharge capacity of the first outlet 213, excess wastewater can be discharged through the second outlet 214, preventing the water collection box 200 from overflowing. Alternatively, the second outlet 214 can be connected to different treatment pipelines to separate liquids of different properties (such as clearer water at the top and water with high mud content at the bottom). The first outlet 213 and the second outlet 214 can be connected to the main sewage pump and backup sewage pipeline inside the base station, respectively, or correspond to different discharge modes (such as a high-powered sewage discharge mode and an energy-saving sewage discharge mode). This dual-outlet design not only improves the system's safety redundancy and prevents overflow accidents caused by blockage or insufficient discharge at a single outlet, but also provides users with a more flexible wastewater management strategy to adapt to various complex cleaning conditions.

[0042] Specifically, the water collection box 200 is provided with a pull-out part 230, which is located at the opening of the water collection box 200 facing the receiving cavity 111.

[0043] The pull-out part 230 can be an outwardly protruding handle, groove, pull ring, or an extension wing integrally formed with the box body. Its position is designed with ergonomics in mind, ensuring a natural and comfortable grip for the user when standing or bending over. Once the water collection box 200 slides into the receiving cavity 111, a portion of the pull-out part 230 can be exposed on the outside of the chassis structure 100 or through a pre-reserved operating window, facilitating direct force application by the user. In terms of structural strength, the connection between the pull-out part 230 and the box body 210 is typically thickened or reinforced to withstand the overall weight when filled with wastewater, preventing breakage or deformation during the pull-out process. The pull-out part 230 facilitates the user's removal of the water collection box 200 from the receiving cavity 111. By providing a clear point of force application, the pull-out part 230 transforms a potentially difficult prying action into a simple linear pull-out action, effectively reducing operational difficulty and improving maintenance convenience.

[0044] Furthermore, the water collection box 200 is provided with a support part 240, which is located at the bottom of the water collection box 200.

[0045] The support 240 can be a pair of feet distributed at the four corners of the box bottom, a reinforcing rib frame extending along the edge, or a full-surface anti-slip mat. When the water collection box 200 is removed from the chassis structure 100 and placed on the ground, countertop, or next to a cleaning pool, the support 240 ensures that the box maintains a stable upright posture, preventing it from tipping over due to uneven bottom or slippery ground, and avoiding secondary spillage of sewage into the surrounding environment. In addition, the support 240 raises the bottom wall of the box body 210 a certain distance from the contact surface, creating an air circulation gap. This not only helps the outside of the box dry, preventing long-term moisture corrosion of the bottom, but also makes it easier for users to rinse the outside of the box bottom with a water gun during cleaning, leaving no dead corners for hygiene. The support 240 makes it easy to place the water collection box 200 on the ground. This detailed design reflects a thorough consideration of the user's actual usage scenario, ensuring the independent stability and easy cleaning of the water collection box 200 after it is removed from the base station body, further improving the practicality and reliability of the entire sewage collection and maintenance system.

[0046] In one embodiment, the chassis structure 100 includes a cleaning chamber 110 and a bottom plate 120. The bottom plate 120 is detachably connected to the cleaning chamber 110 and surrounds the cleaning chamber 110 to form a receiving cavity 111. The cleaning cavity 112 is located at the top of the cleaning chamber 110, and the drain hole 113 is located through the bottom of the cleaning chamber 110.

[0047] Specifically, the cleaning chamber 110, as the upper main body of the chassis structure 100, typically adopts a one-piece injection-molded shell structure, and its internal space constitutes the main fluid handling area. The bottom plate 120, as a sealing component, is sealed and fixed to the lower edge of the cleaning chamber 110 through threaded fasteners, snap-locking mechanisms, or slide rail insertion. After the two are combined, a complete receiving cavity 111 is defined inside. This cavity not only provides installation space for the water collection box 200, but can also be used to arrange auxiliary components such as sewage pumps, pipelines, and control circuits. The cleaning chamber 112 is located at the top opening of the cleaning chamber 110, directly receiving the cleaning operation at the bottom of the lawnmower; the drain hole 113 vertically penetrates the bottom wall of the cleaning chamber 110, serving as the only fluid channel connecting the upper cleaning area and the lower collection area.

[0048] This modular design, compared to the limitations of traditional integral welding or gluing processes, allows the chassis structure 100 to be disassembled into flat components during transportation, storage, and maintenance, significantly reducing logistics costs and improving assembly flexibility. The detachable base plate 120 and cleaning chamber 110 facilitate the assembly and disassembly of the chassis structure 100. In maintenance scenarios, if deep-seated dirt needs to be cleaned from the housing 111 or internal piping needs to be inspected, technicians only need to unlock the base plate 120 to fully open the housing 111, without having to flip the entire base station or disassemble external decorative parts, greatly simplifying the maintenance process. Furthermore, this modular design allows for the replacement of cleaning chambers 110 of different depths or shapes for different types of lawnmowers, while retaining the universal base plate 120 component, thereby improving the versatility and scalability of the product platform.

[0049] During assembly, the base plate 120 can be combined with the cleaning chamber 110 first, or the water collection box 200 can be installed in the receiving cavity 111 first, and then the base plate 120 can be connected to the cleaning chamber 110. This flexible assembly sequence provides the production line with multiple process options: either the chassis body can be sealed first on the final assembly line, and then the water collection box 200 can be pushed in through the side or bottom opening; or the water collection box 200 can be pre-positioned on the base plate 120, and then the base plate 120 and the water collection box 200 can be installed together under the cleaning chamber 110 and locked in one go. The latter method is particularly beneficial for ensuring the alignment accuracy of the water collection box 200 and the drain hole 113, avoiding the misalignment risk that may occur when installing the water collection box separately, and reducing repeated adjustment actions in the assembly process, effectively improving production efficiency.

[0050] Furthermore, the base plate 120 is provided with a support portion 121, which protrudes from the bottom of the receiving cavity 111 and is used to support the water collection box 200.

[0051] The specific form of the support 121 can be an annular protrusion extending upward along the inner surface of the base plate 120, a cross-shaped array of reinforcing ribs, or several evenly distributed support columns. These protruding structures define the installation height of the water collection box 200 in the vertical direction, maintaining a preset gap between its bottom and the base plate 120, or the support 121 directly bears the gravity load of the water collection box 200 when fully loaded. By precisely controlling the height dimension of the support 121, it can be ensured that the inlet of the water collection chamber 211 at the top of the water collection box 200 and the outlet of the drain hole 113 at the bottom of the cleaning chamber 110 are at the optimal docking distance. Setting the support 121 allows the water collection box 200 to be closer to the drain hole 113, shortening the vertical drop between the drain hole 113 and the water collection chamber 211, which can effectively reduce splashing and atomization during the sewage falling process and prevent aerosols containing pathogens from spreading to other areas of the receiving chamber 111.

[0052] In one embodiment, the base plate 120 is provided with a guide surface 122, which is set at an angle to the opening direction of the receiving cavity 111, and the guide surface 122 is used to guide the water collection box 200 into the receiving cavity 111.

[0053] The guide surface 122 is typically machined at the edge of the base plate 120 facing the opening of the receiving cavity 111, or integrated into the inlet end of the support portion 121. Its surface is characterized by a smooth slope, a rounded transition, or a flared shape. When the user pushes the water collection box 200 into the receiving cavity 111, even if there is a slight deviation in the initial insertion angle, the corners or sidewalls of the water collection box 200 will first contact the guide surface 122. Under the action of the thrust, the guide surface 122 generates a normal component force, automatically correcting the movement trajectory of the water collection box 200 and guiding it to the correct central axis. The guide surface 122 can guide the water collection box 200 to a preset installation position when it enters the receiving cavity 111. This self-alignment mechanism significantly reduces the user's requirements for operational precision and avoids problems such as scratches on plastic parts, jamming, or damage to seals caused by forced insertion. Especially in operating environments with insufficient light or obstructed vision, the physical guidance provided by the guide surface 122 allows the water collection box 200 to slide smoothly and unobstructed into place and achieve precise docking with the drain hole 113, greatly improving the smoothness of human-computer interaction and the durability of the product.

[0054] Furthermore, the cleaning device 300 includes a cleaning assembly 310 and a scraper assembly 340. The water outlet of the cleaning assembly 310 is located inside the cleaning chamber 112, and the scraper assembly 340 is movably connected to the chassis structure 100. The scraper assembly 340 is used to push the sewage in the cleaning chamber 112 into the drain hole 113.

[0055] The cleaning assembly 310, as an active cleaning unit, is equipped with nozzles that can generate high-pressure jets or wide-angle atomized water flow to effectively remove stubborn dirt from the lawnmower's blades, axles, and chassis crevices. The scraper assembly 340, as a passive or active auxiliary cleaning unit, is designed to balance rigidity and flexibility, typically made of wear-resistant rubber or polymer composite materials. This ensures that it can closely adhere to the bottom surface of the cleaning chamber 112 during movement without damaging the base station surface or its own structure due to excessive frictional resistance. Working together, they form a closed-loop cleaning logic of "rinsing-scraping": first, the cleaning assembly 310 uses fluid impact to loosen the dirt and suspend it in water; then, the scraper assembly 340 intervenes, using mechanical thrust to directionally drive the wastewater containing suspended matter to the lower drain hole 113, thereby eliminating residue caused by liquid surface tension. The cleaning assembly 310 can be used to spray water to clean the lawnmower. By precisely controlling water pressure, flow rate, and spray angle, the cleaning assembly 310 can achieve comprehensive, thorough cleaning without damaging the lawnmower's delicate electronic components. Especially in areas with severe grass clipping, the high-pressure water flow effectively cuts and washes away the debris. The scraper assembly 340 pushes wastewater to the drain hole 113, preventing residue in the cleaning chamber 112. After cleaning, a thin film of water or scattered impurities often remains on the bottom surface of the cleaning chamber 112, which cannot be completely emptied by gravity alone. The scraper assembly 340, through reciprocating or unidirectional movement, physically removes these residual liquids, forcing them into the drain channel. This not only keeps the inside of the cleaning chamber 112 dry and clean, preventing secondary contamination of the next lawnmower, but also effectively reduces the evaporation time of wastewater in the open chamber, inhibiting odor generation and bacterial growth.

[0056] Furthermore, the lawnmower cleaning station 10 also includes a filter element 400, located between the drain hole 113 and the water collection chamber 211, for filtering wastewater. The filter element 400 can be designed as a detachable filter screen, filter basket, or multi-layer composite filter cotton, with its mesh size selected according to the characteristic dimensions of the main impurities (such as grass clipping length and sediment particle size). The installation position of the filter element 400 is crucial; it should be adjacent to the outlet end of the drain hole 113 or the inlet end of the water collection chamber 211, forming the first solid-liquid separation barrier. When mixed wastewater flows through this area, large solid particles are intercepted above or inside the filter element 400, while the liquid flows smoothly into the water collection chamber 211. This pre-filtration design effectively protects the subsequent sewage pump, pipelines, and water collection box 200 from blockage or wear by large debris, extending the service life of core components. In addition, the filter element 400 can be designed to be removed together with the water collection box 200 or extracted independently, which makes it convenient for users to clean up the trapped grass clippings at the same time when dumping sewage, realizing the classification and treatment of solid and liquid waste and simplifying the maintenance process.

[0057] In one embodiment, the cleaning assembly 310 includes a first cleaning component 311 and a second cleaning component 312. The first cleaning component 311 is located at the center of the cleaning chamber 112, and the second cleaning component 312 is located at the edge of the cleaning chamber 112. The water outlets of both the first cleaning component 311 and the second cleaning component 312 are located inside the cleaning chamber 112, preferably facing the chassis and sides of the lawnmower. The first cleaning component 311 typically uses a rotating nozzle or a multi-hole direct-fire nozzle to specifically target the central area of ​​the lawnmower's bottom, i.e., the blade mounting position and the motor heat dissipation vent, for high-intensity, targeted rinsing to ensure the cleanliness of the core components. The second cleaning component 312 is evenly distributed or arranged in a ring around the circumference of the cleaning chamber 112, with its spray direction slightly tilted inward, forming a three-dimensional water curtain covering the sides of the lawnmower, the outer side of the wheel assembly, and the edge of the chassis. This layout strategy combining the center and the edge creates a comprehensive cleaning coverage network, eliminating blind spots that may exist with a single water source. Regardless of the position in which the lawnmower enters the cleaning chamber 112, the first cleaning component 311 and the second cleaning component 312 can work together to ensure that the bottom and sides of the machine body can receive effective water flow rinsing, significantly improving the overall cleaning efficiency and uniformity.

[0058] Furthermore, the cleaning device 300 also includes a water tank assembly 320, which is connected to the cleaning assembly 310 via pipes to supply water to the cleaning assembly 310. The water tank assembly 320 serves as the water reservoir for the entire cleaning system, and its capacity is designed to meet the needs of multiple continuous cleaning operations. The connecting pipes can be food-grade silicone tubing or rigid PVC tubing, with check valves installed at key points to prevent backflow. The water tank assembly 320 can also integrate a water level sensor to monitor the remaining water level in real time and automatically trigger an alarm or pause the cleaning program when water is insufficient, protecting the water pump from damage due to dry running. In addition, a heating module or detergent dispensing device can be optionally installed in the piping system to enhance the effectiveness of hot water cleaning or chemical decontamination, adapting to cleaning needs of different seasons and varying degrees of dirt.

[0059] In one embodiment, the water tank assembly 320 includes a clean water tank 321 and a wastewater tank 322. The clean water tank 321 is connected to the cleaning assembly 310 via a clean water pump 323, and the wastewater tank 322 is connected to the collection box 200 via a wastewater pump 324 and is used to transport wastewater from the collection box 200 to the wastewater tank 322. The clean water tank 321 is dedicated to storing unused cleaning water, and its material should have light-proof and antibacterial properties to prevent long-term water deterioration. The clean water pump 323 provides stable high-pressure power to transport the clean water in the clean water tank 321 to the cleaning assembly 310 to perform the cleaning task. The wastewater tank 322 serves as a temporary transfer station or final collection container for waste liquid (if it is not directly discharged from the collection box 200), and its volume is usually larger than the maximum amount of wastewater generated in a single cleaning cycle. Wastewater pump 324 has a strong solids-passing capacity, capable of pumping and transferring wastewater that has undergone preliminary sedimentation or filtration in collection box 200 to wastewater tank 322 for temporary storage, or pumping it directly to the external sewer. This dual-tank design with separate clean and wastewater flows completely avoids cross-contamination between clean and dirty water, ensuring that fresh water is used for each cleaning operation, thereby guaranteeing optimal cleaning results and equipment hygiene standards.

[0060] Specifically, the scraper assembly 340 includes a scraper drive 341 and a scraper 342. The scraper drive 341 is mounted on the chassis structure 100, and the scraper 342 is connected to the output end of the scraper drive 341. The end of the scraper 342 abuts against the bottom surface of the cleaning chamber 112. Driven by the scraper drive 341, the scraper 342 pushes the sewage in the cleaning chamber 112 into the drain hole 113. The lower edge of the scraper 342 is typically provided with an elastic scraping lip. In its natural state, the scraping lip is slightly higher than the bottom surface of the cleaning chamber 112, but it undergoes slight deformation under the installation preload or its own weight, forming a line contact seal with the bottom surface. This design ensures tightness when pushing water, preventing sewage from leaking under the scraper, and also reduces the coefficient of friction, reducing drive load and wear noise. The scraper drive 341 is responsible for providing precise motion control, driving the scraper 342 to perform unidirectional sweeping, reciprocating oscillation, or specific trajectory movements to adapt to different stain distributions. In terms of control logic, the action of the scraper assembly 340 can be linked with the start and stop of the cleaning assembly 310, for example, automatically executing the scraping program after the water spraying ends, or starting the emergency drainage mode when the liquid level sensor signal is detected.

[0061] In one embodiment, the number of scraper drive components 341 can be two sets, and the two sets of scraper drive components 341 are symmetrically arranged on opposite sides of the cleaning chamber 112, with the two sets of scraper drive components 341 respectively connected to opposite ends of the scraper 342. This dual-drive symmetrical layout significantly improves the smoothness and synchronization of the scraper 342's movement. When the scraper 342 has a large span, single-point drive can easily lead to uneven force on the distal end, resulting in skewness or jamming, while simultaneous drive at both ends can balance the lateral load, ensuring that the scraper 342 remains parallel and in contact with the bottom surface throughout the entire stroke, avoiding local gaps that could lead to sewage residue. In addition, the dual-drive structure also provides a redundant safety mechanism; if one drive fails, the other can still maintain basic operation or issue a fault alarm, improving the system's reliability. Specifically, the scraper drive component 341 can be, for example, a combination of a drive motor and a lead screw transmission structure, or a linear drive scheme such as a linear module. The screw drive system offers advantages such as good self-locking, high positioning accuracy, and large thrust, making it suitable for applications requiring precise control of the scraper position and maintenance of constant thrust. The linear module system, on the other hand, features a compact structure, fast response, and maintenance-free operation, making it suitable for high-frequency, rapid reciprocating cleaning tasks. Regardless of the specific drive method used, the control system can integrate limit switches or Hall effect sensors to precisely define the start and end positions of the scraper 342, preventing overtravel and impact damage to the equipment, and ensuring that each scraping action completely covers the effective area of ​​the cleaning chamber 112.

[0062] In one embodiment, the cleaning device 300 further includes a scrubbing assembly 330, which includes a support roller 331 and a cleaning brush 332. The support roller 331 is rotatably connected to the chassis structure 100, and the cleaning brush 332 is connected to the chassis structure 100. The support roller 331 is used to support the travel wheel of the lawnmower, and the cleaning brush 332 is used to scrub the travel wheel.

[0063] Specifically, the support roller 331 can be made of wear-resistant nylon or rubber-coated metal and is rotatably mounted on a specific bracket of the chassis structure 100 via bearings or pins. Its top surface is slightly higher than or flush with the bottom surface of the cleaning chamber 112, so that when the lawnmower enters, its travel wheels can naturally engage with the support roller 331. This design not only provides the lawnmower with an additional fulcrum, distributing the weight of the machine and preventing heavy lawnmowers from directly pressing against the bottom surface of the cleaning chamber, causing deformation or wear, but more importantly, the rotatable nature of the support roller 331 allows the lawnmower's travel wheels to rotate freely in place or with slight movement, thereby continuously driving different areas of the tire surface through the working range of the cleaning brush 332. The cleaning brush 332 is made of high-density nylon or steel wire bristles flocked together. Its bristle length and hardness are specifically designed to penetrate deep into the tire tread grooves to remove embedded stones, mud, and tangled grass ropes without excessively abrading the tire rubber. During operation, when the lawnmower stops or moves slowly, the support roller 331 rotates with the wheel, and the cleaning brush 332 continuously mechanically scrapes and washes the rotating tire surface. Combined with the water flow sprayed by the cleaning component 310, a combined cleaning effect of "rinsing-brushing-draining" is formed, which effectively solves the pain point of the tire sidewalls and deep treads that are difficult to clean in traditional solutions.

[0064] Furthermore, the cleaning chamber 110 is also provided with a receiving groove 115 that communicates with the cleaning cavity 112, and the brushing assembly 330 is housed in the receiving groove 115.

[0065] The receiving groove 115 is a dedicated installation space formed by a downward indentation along the side wall or bottom of the cleaning chamber 112. Its outline is adapted to the shape of the brush assembly 330, ensuring that the upper part of the support roller 331 is exposed to contact the wheel, while the main body of the cleaning brush 332 and the drive mechanism (if any) are completely hidden in the groove. This embedded layout has multiple technical advantages: First, it avoids the brush assembly 330 protruding from the plane of the cleaning chamber 112 and obstructing the normal entry or exit of the lawnmower, ensuring a smooth and flat passageway; second, the receiving groove 115 forms a natural splash barrier, which can limit the spread of splashed water and spun dirt during brushing to the outside of the base station or other electronic component areas, controlling the pollution within a local area; third, the bottom of the receiving groove 115 can be designed with an independent guide slope or small holes to directly collect the dirty water generated during brushing into the main drain hole 113 or a separate collection channel, preventing sewage from accumulating in the groove and corroding the components. In addition, the design of the receiving tank 115 facilitates modular maintenance. If the scrubbing component 330 needs to be replaced or the tangled material needs to be cleaned, technicians can directly access the tank from above or the side to operate without disassembling the entire cleaning chamber 110, which significantly improves the maintainability and service life of the equipment.

[0066] In one embodiment, the chassis structure 100 further includes a ramp 130 connected to the front end of the cleaning chamber 110. The ramp 130 is provided with an inclined ramp to facilitate the lawnmower entering the cleaning chamber 112 from the ramp 130.

[0067] The ramp component 130 is typically made of high-strength engineering plastic injection molding or metal sheet stamping and bending. Its front end smoothly transitions to the ground, and its rear end is securely connected to the inlet edge of the cleaning chamber 110 via clips, threaded fasteners, or welding. The inclination angle of the ramp is precisely calculated and is usually set between 5° and 20° to accommodate the climbing ability and ground clearance of different lawnmower models. The ramp surface can be further textured with anti-slip textures, transverse ribs, or covered with rubber pads to increase the friction coefficient between the tires and the ramp, preventing the lawnmower from slipping or rolling backward in wet conditions. When the lawnmower performs a recharge task, its drive wheels first contact the ramp component 130, ascend the ramp, and smoothly enter the cleaning chamber 112. This process effectively overcomes the height difference between the bottom surface of the cleaning chamber 112 and the ground, avoiding mechanical damage caused by the lawnmower chassis hitting the inlet edge, and ensuring the smoothness and safety of the automatic return process.

[0068] Furthermore, the chassis structure 100 is provided with a drainage surface 114, which is located at the bottom of the cleaning chamber 112 and is inclined.

[0069] The drainage surface 114 is not perfectly horizontal, but rather has a preset tilt angle relative to the horizontal plane, either entirely or partially, with the tilt direction strictly pointing towards the center of the drainage hole 113. The tilt angle can be optimized based on fluid flow and impurity settling characteristics, for example, set to 2° to 10°. Under gravity, wastewater and suspended particles accumulated at the bottom of the cleaning chamber 112 will naturally converge downwards along the drainage surface 114, forming a directional flow. This structural design eliminates any flat stagnation areas that may exist at the bottom, preventing wastewater from adhering to the bottom of the chamber due to surface tension and forming "puddles," while also reducing the probability of sediment deposition in dead corners. The drainage surface 114 allows for faster wastewater flow to the drainage hole 113. By utilizing gravitational potential energy to convert into fluid kinetic energy, the drainage surface 114 significantly accelerates the wastewater discharge process, shortens the emptying time after cleaning operations, and makes the scraper assembly 340 more efficient and less labor-intensive in pushing wastewater, ensuring that the cleaning chamber 112 can quickly return to a dry state after each operation, thus improving the turnaround efficiency of the base station.

[0070] In one embodiment, the water collection box 200 is slidably engaged with the chassis structure 100.

[0071] This sliding engagement mechanism means that the water collection box 200 and the chassis structure 100 achieve relative linear movement through a specific guide mechanism. Users only need to apply a horizontal pushing or pulling force to pull the water collection box 200 out of the receiving cavity 111. Compared to hinged flipping or completely detachable retrieval, the sliding engagement provides a more stable movement trajectory, avoiding the risk of wastewater spillage due to shaking during retrieval. Simultaneously, the sliding rail can be designed with damping or positioning latches, allowing the water collection box 200 to automatically lock into place when fully pushed in and maintain smooth and stable operation when pulled out, greatly optimizing the human-computer interaction experience. Specifically, the water collection box 200 can be connected to the chassis structure 100 via a linear slide rail. This linear slide rail may include a fixed guide rail installed on the inner wall of the chassis structure 100 and a sliding slider disposed on the outer wall of the water collection box 200. The two achieve rolling or sliding contact through balls, rollers, or wear-resistant pads with a low coefficient of friction. The guide rails can be in one or more pairs, symmetrically distributed on both sides or bottom of the water collection box 200 to ensure uniform force distribution and prevent jamming on one side. In addition, limit blocks can be set at the ends of the guide rails to prevent the water collection box 200 from being pulled out excessively and falling off, or from being pushed in excessively and hitting the internal pipes, thus ensuring operational safety and structural durability.

[0072] Furthermore, the lawnmower cleaning base station 10 also includes a water level sensor, which is located inside the water collection chamber 211.

[0073] Water level sensors can employ various detection principles, such as float type, electrode type, ultrasonic type, or photoelectric type. Their installation location should avoid areas prone to water inrush to prevent false alarms caused by water flow fluctuations. The sensor is electrically connected to the main control circuit board of the base station via wires or a wireless module to monitor changes in the liquid level in the collection chamber 211 in real time. The water level sensor can be used to obtain the sewage level in the collection box 200. Based on real-time water level data, the control system can execute various intelligent logics: when the water level reaches a preset high liquid level threshold, the system can automatically trigger an alarm to prompt the user to clean, or automatically start the sewage pump to transfer the sewage to an external pipeline to prevent overflow and contamination of the base station; when the water level is below the low liquid level threshold, the system can determine that the collection box 200 has been emptied or is not properly installed, thereby prohibiting the start of the cleaning program to avoid dry running and damage to the equipment. This closed-loop feedback mechanism achieves automation and intelligence in sewage management, significantly reducing the frequency of manual inspections and improving the operational reliability of the equipment.

[0074] In one embodiment, the water collection box 200 is provided with an observation window, which is a semi-transparent or transparent structure.

[0075] The observation window is typically made of materials with excellent optical properties, such as plastic, acrylic, or high-transparency glass. It is embedded or integrally molded into the side wall or front baffle of the water collection box 200, and its visible area should cover the main liquid level variation range of the water collection chamber 211. To enhance the accuracy of readings, the outer surface of the observation window may also be engraved with liquid level scale lines or color warning indicators (such as green for normal and red for full load). This facilitates observation of the water level within the water collection box 200. Users can directly and quickly determine the amount of wastewater and its turbidity within the water collection box 200 by visually observing the observation window without opening the base station cover or using the electronic display screen. This design not only helps users grasp the optimal cleaning time and avoid wastewater overflow, but also allows users to check for abnormal sediment buildup inside, providing a convenient visual window for daily maintenance and enhancing the ease of use of the product.

[0076] Furthermore, the lawnmower cleaning base station 10 also includes a sealing strip that seals the opening of the water collection chamber 211 between the chassis structure 100.

[0077] The sealing strip can be made of materials with high elasticity, aging resistance, and corrosion resistance, such as silicone rubber, rubber, or thermoplastic elastomers. Its cross-sectional shape can be designed as O-type, D-type, P-type, or irregular structures to adapt to different compression amounts and sealing requirements. The sealing strip can be fixed to the upper edge of the water collection box 200 or the corresponding contact surface of the chassis structure 100 via adhesive bonding, slot embedding, or two-color injection molding. When the water collection box 200 is pushed into place and locked, the sealing strip undergoes axial or radial compression deformation, filling the microscopic gaps between the water collection box 200 and the chassis structure 100, forming a continuous elastic sealing interface. This ensures a seal between the water collection box 200 and the chassis structure 100. This sealing structure effectively blocks the path of sewage, odor, and insects leaking outward through the interface gaps, prevents the diffusion of bacterial aerosols into the external environment of the base station, and also prevents external dust from entering the water collection chamber 211 and contaminating the water quality. Good sealing performance is a key guarantee for ensuring the hygiene of the base station, preventing short circuits, and extending the service life of the equipment. The reliable role of the sealing strip is especially important under long-term high humidity and high pollution conditions.
