Description

Technical Field

[0001] This application relates to the field of intelligent lawnmower maintenance equipment technology, and in particular to a lawnmower base station integrating a water supply system. Background Technology

[0002] Intelligent lawn mowing robots are now widely used in lawn maintenance scenarios such as courtyards and parks. After the equipment operates, the chassis, blades and other parts are prone to adhering to grass clippings, mud and other impurities, which usually require the support of a base station to achieve automatic cleaning and maintenance.

[0003] Most lawnmower cleaning stations on the market currently only use a single spray cleaning mode, which is insufficient for cleaning. They are either ineffective at cleaning stubborn deposits or fail to thoroughly clean the components of the equipment. This results in high water consumption during the cleaning process and a significant waste of water resources. Summary of the Invention

[0004] The purpose of this application is to at least overcome the technical problems existing in the above-mentioned related technologies and provide a lawnmower base station that can enrich the cleaning modes of the lawnmower base station. In actual use, different modes can be selected as needed to clean the lawnmower, improve the cleaning effect, and balance the water consumption in the cleaning process to avoid waste of water resources.

[0005] To achieve the above objectives, this application provides a lawnmower base station, comprising: The base station body includes a base assembly that allows a lawnmower to enter; A water supply system includes a water supply pump, a three-way pipe, a valve assembly, a first cleaning assembly, and a second cleaning assembly. The water supply pump, the first cleaning assembly, and the second cleaning assembly are respectively connected to the three ports of the three-way pipe. The water supply pump is used to connect to a water supply device to pump the cleaning water from the water supply device to the first cleaning assembly and the second cleaning assembly, respectively. The outlet flow rate and / or outlet pressure of the first cleaning assembly and the second cleaning assembly are different. A valve assembly is provided between the first cleaning component and the three-way pipe, and between the second cleaning component and the three-way pipe, respectively. The valve assembly is used to control the flow rate of cleaning water flowing out of the corresponding interface of the three-way pipe.

[0006] In one embodiment, the first cleaning component is disposed on the bottom surface of the base assembly, with the water outlet facing upward, to rinse the bottom of the lawnmower that enters the base station body.

[0007] In one embodiment, the first cleaning component and the second cleaning component each have multiple water outlets. The water outlet of the first cleaning component is located in the middle area of ​​the base component, and the water outlet of the second cleaning component is located in the peripheral area of ​​the base component and faces the middle area. The second cleaning component surrounds the first cleaning component therein.

[0008] In one embodiment, the outlet of the second cleaning component is inclined toward the upper surface of the base component.

[0009] In one embodiment, the water supply system further includes a controller, each valve assembly including a valve body and an actuator drivenly connected to the valve body, the controller being connected to each actuator to control the opening degree of the corresponding valve body through the actuator.

[0010] In one embodiment, the water supply pump, the three-way pipe, and the valve assembly are all located on the back of the base assembly. A portion of the first cleaning assembly and a portion of the second cleaning assembly are located on the back of the base assembly, while a portion penetrates the base assembly and is exposed on the upper surface of the base assembly.

[0011] As one embodiment, the base assembly has a waste collection port; The lawnmower base station also includes a liquid circulation tank assembly, which is connected to the waste collection port to collect waste generated after the lawnmower is cleaned.

[0012] As one implementation, the lawnmower base station further includes: A wastewater tank is connected to the liquid circulation tank assembly to collect wastewater discharged from the liquid circulation tank assembly.

[0013] In one embodiment, the wastewater tank includes a wastewater inlet, a clean water outlet, and a water purification component disposed between the wastewater inlet and the clean water outlet, wherein the clean water outlet is connected to the inlet of the water supply pump.

[0014] In one embodiment, the water supply device includes a water tank connected to the inlet of the water supply pump.

[0015] The lawnmower base station provided in this application is equipped with a novel water supply system. This system uses a three-way pipe to split the cleaning water from the water supply device into two branches, each connected to a cleaning component of different specifications. Each branch's valve assembly controls the water output of the different cleaning components, allowing the two cleaning components to operate independently or simultaneously. The valves can precisely regulate the water output, matching the cleaning intensity as needed, reducing ineffective spraying, and lowering water consumption. Therefore, this application can achieve combined cleaning with different pressures and flow rates, enriching the cleaning modes and balancing cleaning effectiveness with appropriate water consumption, thus avoiding water waste.

[0016] In addition, the wastewater from cleaning can be recycled, filtered, purified, and reused, which greatly improves the utilization rate of water resources and avoids waste of resources. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] It should be noted that the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to direct setup or connection, or indirect setup or connection through centered components or centered structures.

[0021] Furthermore, in the embodiments of this application, terms such as "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" are used to indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings or in a conventional placement or usage state. These terms are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure, feature, device, or element referred to must have a specific orientation or positional relationship, nor that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In the description of this application, unless otherwise stated, "multiple" means two or more.

[0022] The various specific technical features and embodiments described in the detailed implementation can be combined in any suitable manner without contradiction. For example, different implementation methods can be formed by combining different specific technical features / implementations. In order to avoid unnecessary repetition, the various possible combinations of the various specific technical features / implementations in this application will not be described separately.

[0023] In related technologies, if the intelligent lawnmower base station uses a single water path and a single set of spray structures for cleaning, the water path structure is simple and the water output parameters are fixed, making it impossible to match the corresponding cleaning intensity to the dirt characteristics of different parts of the lawnmower robot. After the lawnmower robot has finished operating, thick and compacted grass clippings, mud, and other stubborn impurities adhere to the blade and chassis. A single low-pressure spray cannot effectively remove them, and cleaning residue is very likely to occur. On the other hand, if high-pressure, high-flow-rate spraying is used throughout the process, it will result in a large amount of ineffective water loss, and the cleaning energy and water consumption will remain high.

[0024] Meanwhile, base stations often lack comprehensive wastewater recycling and purification systems, resulting in direct discharge of cleaning wastewater. This not only causes significant water waste but also pollutes the lawn environment with scattered wastewater and debris, making the base station equipment less environmentally friendly and economical. Furthermore, traditional cleaning water systems lack independent opening control mechanisms and cannot adaptively adjust water flow or pressure based on the degree of dirtiness of the lawnmower. The cleaning modes are rigid, lack intelligence, and have poor adaptability.

[0025] To address the aforementioned technical deficiencies, this application designs a dual-path, independently controllable, differentiated spray water circuit, coupled with a wastewater recycling and purification closed-loop circulation system. Through cleaning components with different outlet water pressures and flow rates, it achieves precise cleaning by zone and grade. At the same time, through electrically adjustable valve components, it independently controls the outlet water status of each water circuit, and is equipped with a waste recycling and wastewater purification return structure. Structurally, it completely solves the technical problems of incomplete cleaning, water waste, single operating conditions, and poor adaptability of traditional base station cleaning.

[0026] Figure 1 This illustration shows a schematic diagram of the usage status of a lawnmower base station provided in an embodiment of this application; Figure 2 This illustration shows a schematic diagram of the internal structure of a lawnmower base station provided in an embodiment of this application; Figure 3 This illustration shows a three-dimensional structural diagram of the front of a lawnmower base station provided in an embodiment of this application; Figure 4 A schematic diagram of the water supply system for a lawnmower base station provided in an embodiment of this application is shown.

[0027] like Figure 1-4 As shown, an embodiment of this application provides a lawnmower base station 100, including a base station body 101 and a water supply system 111. The base station body 101 serves as the main frame of the base station, which can be used to support and install various components, and is a carrier that provides basic functions such as parking, charging, and storage for the lawnmower. The water supply system 111 is mainly used to provide a source of cleaning water for rinsing the lawnmower body, blades, and other parts.

[0028] In some embodiments, the base station body 101 includes a base assembly 102, which serves as a docking platform for lawnmowers to drive into and park, guiding the lawnmowers to accurately drive into the designated parking location.

[0029] Combination Figure 3 and Figure 4 As shown, the water supply system 111 is installed inside the base station body 101 and includes a water supply pump 112, a three-way pipe 113, a valve assembly 114, a first cleaning assembly 115, and a second cleaning assembly 116. The water supply pump 112, the first cleaning assembly 115, and the second cleaning assembly 116 are respectively connected to the three ports of the three-way pipe 113. The water supply pump 112 is used to connect to the water supply device to pump the cleaning water from the water supply device to the first cleaning assembly 115 and the second cleaning assembly 116 respectively.

[0030] In some embodiments, the first cleaning component 115 and the second cleaning component 116 have at least one different outlet flow rate and outlet water pressure, thereby providing different cleaning effects. Specifically, a valve assembly 114 is provided between the first cleaning component 115 and the three-way pipe 113, and between the second cleaning component 116 and the three-way pipe 113, respectively. The valve assembly 114 is used to control the flow rate of the cleaning water flowing out of the corresponding interface of the three-way pipe 113. For example, the outlet water flow rate and pressure of the first cleaning component 115 are both greater than those of the second cleaning component 116. The first cleaning component 115 can be used for high-flow rinsing, while the second cleaning component 116 can be used for low-flow spraying.

[0031] By employing a three-way pipe to divide the water path into two, and combining them with two sets of cleaning components with different water output parameters, the appropriate cleaning intensity can be matched to different dirty parts of the lawnmower. Independently deployed valve components allow for individual control of the on / off status and water flow of each water path, eliminating the need for a single spray mode. Either cleaning structure can be started or stopped individually as needed, switching to a differentiated cleaning mode to target and remove lightly or heavily soiled grass clippings, mud, and other impurities. Simultaneously, the two water paths can be activated and work in tandem, forming a three-dimensional, full-coverage spray cleaning water curtain through a combination of concentrated high-pressure rinsing and surrounding low-pressure auxiliary spraying. This effectively removes stubborn, compacted dirt from the chassis and blades with high-pressure water flow, while also cleaning residual debris from machine edges and corners with a wide-area spray. The complementary use of strong and weak water flows completely eliminates cleaning blind spots, significantly improving the uniformity and cleanliness of the entire machine. Compared to a single cleaning mode, both cleaning efficiency and cleaning quality are doubled.

[0032] For example, the cleaning system can be flexibly activated or deactivated individually based on the actual dirt level of the lawnmower. Specifically, when only the first cleaning component is activated, high-pressure, concentrated water flow can be used to target heavily soiled and stubborn dirt and compacted grass clippings on the chassis and blades, making it suitable for heavily soiled cleaning scenarios. When only the second cleaning component is activated, a large-coverage, low-pressure, gentle water flow can be used to complete the routine cleaning of floating dust and loose debris on the entire machine, making it suitable for daily light cleaning and maintenance. This allows for precise individual adaptation to light and heavy working conditions, effectively avoiding water waste caused by ineffective water spraying.

[0033] For example, when two cleaning components are activated simultaneously based on the actual soiling condition of the lawnmower, the first cleaning component creates a high-pressure direct water jet at the center of the base, impacting and removing stubborn deposits from the blades and the heavily soiled core areas of the chassis. The second cleaning component creates an inclined, surrounding spray curtain, thoroughly cleaning the lawnmower's side walls, wheel assembly, chassis edges, and other areas prone to dirt accumulation. High-pressure targeted dirt removal and low-pressure all-area cleaning work in tandem, complementing each other. This differentiated dual-flow structure allows for the simultaneous removal of stubborn dirt, cleaning of loose debris, and rinsing of the entire machine's surface in the same cleaning process. This completely solves the shortcomings of traditional single-flow cleaning, such as limited intensity, incomplete coverage, and numerous dead-angle residues. It significantly shortens the overall cleaning time, significantly improving cleaning cleanliness and uniformity while eliminating ineffective water consumption through intelligent division of labor in the spray mode, balancing cleaning effectiveness and energy efficiency.

[0034] In some embodiments, the first cleaning component 115 is fixedly installed on the bottom surface of the base component 102, with its outlet facing upwards, to rinse the bottom of the lawnmower 200 entering the base station body 101. This bottom-up high-pressure rinsing arrangement allows the water flow to be perpendicular to the cutting area of ​​the lawnmower's blade and the flat attachment area of ​​the chassis. The water flow impact force acts perpendicularly on the soiled surface, minimizing force loss and maximizing impact efficiency. For compacted and clumped soil and tangled grass clippings after mowing, the high-pressure direct water flow can break down and quickly peel them off layer by layer, avoiding the problems of dispersed impact force and ineffective cleaning of heavy soil in traditional oblique water flow. It precisely enhances the cleaning ability of core heavily soiled areas, ensuring that the core components of the robot are clean and residue-free, and preventing malfunctions such as blade jamming and increased rotational resistance caused by long-term dirt accumulation.

[0035] In some embodiments, the first cleaning component 115 and the second cleaning component 116 are each provided with a plurality of independent water outlets. The water outlets of the first cleaning component 115 are distributed in the middle region of the base component 102, and the water outlets of the second cleaning component 116 are distributed in the peripheral region of the base component 102 and face the middle region. The second cleaning component 116 surrounds the first cleaning component 115 therein.

[0036] In this embodiment, the water outlets are arranged in sections at the center and periphery of the base assembly 102, employing a zoned layout of concentrated central spraying and surrounding peripheral spraying, ensuring that the cleaning area completely covers the robot's bottom projection range. The central area of ​​the base assembly 102 relies on the high-density water outlets of the first cleaning component to form a concentrated rinsing zone, ensuring no blind spots in the core area; the peripheral area of ​​the base assembly 102 relies on the ring-shaped water outlets of the second cleaning component to form a surrounding water curtain, sealing off outer dead corners and preventing debris from escaping and remaining at the chassis edges. The double-layer surrounding spray layout achieves full-coverage cleaning without dead corners, significantly improving the integrity of cleaning coverage compared to traditional spray structures and completely solving the problem of inadequate edge cleaning.

[0037] In some embodiments, such as Figure 3 As shown, the water outlet of the second cleaning component 116 is inclined towards the upper surface of the base component 102. During the operation of the second cleaning component 116, the inclined water outlet angle provides an inward and downward spray trajectory for the surrounding spray water flow. The water flow can obliquely wash the inside of the mower's wheels, the chassis folds, the bottom of the machine's side walls, and other dead corners that cannot be covered by vertical water spray, thus compensating for the limited coverage of vertical water spray. The inclined water flow has both sweeping and rinsing effects, which can change the direction of water spray, washing away and collecting fine grass clippings remaining at the edges towards the center, and then flushing them out with the central high-pressure water flow, further improving the uniformity and cleanliness of the entire machine cleaning.

[0038] Figure 5 A schematic diagram of a valve assembly provided in an embodiment of this application is shown; Figure 6 A control system block diagram of a water supply system provided in an embodiment of this application is shown.

[0039] In some embodiments, such as Figure 5 and Figure 6 As shown, the water supply system 111 also has a built-in controller Q. Each valve assembly 114 includes a valve body 1140 and an actuator 1141 that is driven and connected to the valve body 1140. The controller Q is connected to each actuator 1141 to control the opening degree of the corresponding valve body 1140 through the actuator 1141.

[0040] In some embodiments, the actuator 1141 can be a common on / off solenoid valve, and the valve body 1140 can have two opening levels: open and closed. The controller Q can control the opening and closing of the valve body 1140 through the solenoid valve. In some embodiments, the actuator 1141 can be an electrically controlled stepless opening adjustment structure. Unlike traditional common on / off solenoid valves, the valve body 1140 can have more than two opening levels. That is, in addition to open and closed, the opening itself has multiple opening degrees, which can realize precise and continuous adjustment of water flow and water pressure. For example, the lawnmower base station has a detection module for detecting the degree of dirt on the robot, or a preset cleaning program. The controller can accurately control the opening and closing degree of the valve body according to the preset cleaning program or the robot dirt detection data, realizing multi-level adaptive adjustment of small opening for light cleaning, medium opening for regular cleaning, and large opening for heavy cleaning. The two valve components are independently controlled and do not interfere with each other. They can achieve single-channel fine-tuning and dual-channel ratio adjustment, intelligently matching different dirty working conditions. This can avoid excessive water spraying and waste of water resources, and also prevent insufficient opening from causing incomplete cleaning, greatly improving the intelligent adaptability of the equipment.

[0041] Figure 7 This paper shows a schematic diagram of the internal waterway structure of a lawnmower base station according to an embodiment of the present application; Figure 8 for Figure 7 Enlarged view of point B in the middle; Figure 9 This illustration shows a top view of a lawnmower base station provided in an embodiment of this application; Figure 10 An oblique side view of a lawnmower base station provided in an embodiment of this application is shown.

[0042] Combination Figure 5-10 As shown, in some embodiments, the water supply pump 112, the tee pipe 113, and the valve assembly 114 are all uniformly installed on the back of the base assembly 102, and a portion of the first cleaning assembly 115 and the second cleaning assembly 116 are located on the back of the base assembly 102 (e.g., Figure 7 , 8 A portion of it penetrates the base assembly 102 and is exposed on the upper surface of the base assembly 102 (e.g., Figure 9 That is, both the first cleaning component 115 and the second cleaning component 116 have a portion of pipes that pass through and are fixed to the base component 102. The portion located on the back of the base component 102 is connected to the outlet of the valve body 1140 of the corresponding valve component 114 through the pipes. Both the first cleaning component 115 and the second cleaning component 116 have a portion of pipes located above the base component 102 to rinse the corresponding parts of the lawnmower 200 that enter the base component 102.

[0043] For example, combined Figure 3 , 9As shown in Figure 10, the first cleaning component 115 located above the base component 102 is a flushing structure facing the chassis of the lawnmower 200, and it has several high-pressure water outlets. The second cleaning component 116 located above the base component 102 is an annular spray pipe fixed on the surrounding frame of the base component 102. The inner part of the spray pipe has several spray nozzles. When the lawnmower 200 enters the station, each spray nozzle of the spray pipe is arranged around the lawnmower 200 and sprays water downwards. On the one hand, it can wash the surrounding parts of the lawnmower 200. On the other hand, it can also carry dirt downwards to the waste collection port 1020, and it can also form a shielding water curtain to block the outer dead corners and prevent debris from escaping outwards and remaining on the edge of the chassis.

[0044] Because most of the core water channels and control components of the lawnmower base are concealed and integrated into the back of the base, with only the water outlets of the various cleaning components exposed on the front, the overall structure is compact and well-organized. This effectively prevents mud, sand, and wastewater from directly accumulating on the pipe surfaces during operation and cleaning, thus preventing pipe blockage, corrosion, and damage from impacts. In addition, the centralized layout can minimize the length of the water supply pipeline, reduce water resistance and pressure loss along the water path, ensure stable outlet pressure and uniform water output, and improve the stability of the spray cleaning operation and the service life of the equipment.

[0045] Specifically, such as Figure 4 and Figure 5 As shown, a bracket 117 can also be installed on the back of the base assembly 102. Two valve assemblies 114 are fixed on the bracket 117, and a three-way pipe 113 is located on one side of the bracket 117. The inlet of the valve assembly 114 is connected to the interface of the three-way pipe 113, and the outlets of the two valve assemblies 114 are respectively connected to the corresponding first cleaning assembly 115 and second cleaning assembly 116 through different pipes (not shown) located on the back of the base assembly 102.

[0046] If the wastewater generated during the cleaning process is discharged directly, it will not only cause serious waste of water resources, but the scattered wastewater and debris will also pollute the lawn environment, and the environmental friendliness and economic efficiency of using base station equipment will also deteriorate. Figure 2 As shown, some embodiments of this application also have a waste collection port 1020 on the base assembly 102. The waste collection port 1020 can be located at the lowest point of the base assembly 102 so that the waste generated during cleaning can be automatically collected under the action of gravity.

[0047] Correspondingly, the lawnmower base station 100 also includes a liquid circulation tank assembly 1, which is connected to the waste collection port 1020 to collect the waste generated after the lawnmower 200 is cleaned. Once the liquid circulation tank assembly 1 is installed, wastewater, shed grass clippings, and sediment generated during base station cleaning can be quickly collected from the waste collection port 1020 into the liquid circulation tank assembly 1. This prevents wastewater from accumulating on the back of the base assembly 102 and soaking the equipment components, thus preventing malfunctions such as metal corrosion and circuit dampness caused by long-term moisture accumulation. The liquid circulation tank assembly 1 can initially settle large particles of impurities, achieving preliminary separation of wastewater and wastewater, providing pretreatment for subsequent wastewater purification and circulation, and reducing the probability of clogging of the downstream water purification components.

[0048] In some embodiments, the lawnmower base station 100 also includes a wastewater tank 2, the inlet of which is connected to a liquid circulation tank assembly 1 to collect wastewater discharged from the liquid circulation tank assembly 1. By classifying and collecting wastewater and transferring waste liquid step by step, the liquid circulation tank assembly 1 serves as a temporary buffer sedimentation transfer tank, and the wastewater tank 2 serves as the final collection container. This enables centralized collection and treatment of cleaning wastewater, preventing disorderly flow and overflow of wastewater that pollutes the lawn, effectively improving the problems of indiscriminate wastewater discharge and messy site conditions associated with traditional base stations, and enhancing the environmental friendliness and adaptability of the equipment. For example, a solid-liquid separation system can also be installed inside the liquid circulation tank assembly 1 to separate solid waste from the waste, and the resulting wastewater directly enters the wastewater tank 2.

[0049] Of course, a water purification component can be further installed inside the wastewater tank 2. Specifically, the wastewater tank 2 includes a wastewater inlet, a clean water outlet, and a water purification component located between the wastewater inlet and the clean water outlet. The clean water outlet is connected to the inlet of the water supply pump 112. After the wastewater enters the wastewater tank 2, it undergoes multi-stage filtration, sedimentation, and purification treatment. Large particles of silt and grass debris are intercepted, and suspended solids and impurities in the water are effectively filtered out. The purified clean water meets the standards for cleaning water and can be directly returned to the inlet of the water supply pump 112 to participate in the spray cleaning operation again. This closed-loop water circulation structure can realize the resource reuse of wastewater, significantly reduce the frequency of external clean water access, fundamentally reduce the water consumption of cleaning operations, and achieve significant energy-saving and environmental protection effects.

[0050] In some embodiments, the lawnmower base station 100 further includes a suction mechanism and a trash can 3. The liquid circulation tank assembly 1 also has an air inlet and an air outlet. The air outlet is connected to the suction end of the suction mechanism to collect the garbage in the waste entering the liquid circulation tank assembly 1 into the trash can 3 under the suction force of the suction mechanism. The air inlet is connected to the exhaust end of the suction mechanism to form a circulating suction loop with the air outlet and the suction mechanism.

[0051] This embodiment adds an independent suction mechanism and a waste bin 3 to the lawnmower base station 100, and uses the suction end and exhaust end of the suction mechanism to connect to the air outlet and air inlet respectively, to construct a closed-loop circulating suction air path within the lawnmower base station 100. When the mixed waste generated by the base station cleaning enters the liquid circulation tank assembly 1, the suction mechanism is activated, and the suction end generates a continuous negative pressure suction force, which can adsorb and extract the light grass clippings, fine mud and sand and other solid waste floating in the liquid circulation tank assembly 1; at the same time, the airflow output from the exhaust end flows back into the liquid circulation tank assembly 1 through the air inlet, forming an airflow circulation disturbance. Compared to static filtration, this closed-loop suction circuit can actively extract suspended and accumulated solid waste in the liquid circulation tank component 1, preventing waste from accumulating and clogging at the bottom of the liquid circulation tank component 1. At the same time, there is no need to add an air blowing device. Airflow circulation can be achieved by relying on the suction mechanism. The structure is simplified and the energy consumption is lower. It can automatically collect solid waste and transport it to the waste bin 3 to achieve automatic solid-liquid separation, which can significantly reduce the frequency of manual cleaning.

[0052] In some embodiments, the water supply device itself may also include a water tank, which is connected to the inlet of the water supply pump 112. The built-in independent water tank can independently store cleaning water, allowing the lawnmower base station 100 to operate without relying on a municipal water source. It can independently complete fully automatic cleaning operations in courtyards and outdoor areas without a fixed water supply interface, greatly expanding the applicable scenarios for the equipment. Simultaneously, the water tank can be used in conjunction with the wastewater tank 2 and the water supply pump 112 to form a circulating clean water loop. Through this dual protection structure of clean water storage and wastewater circulation, the equipment can still operate stably after long periods of continuous cleaning operations.

[0053] An embodiment of this application provides a lawnmower base station 100, which is composed of a base station body 101, a water supply system 111, a liquid circulation tank assembly 1, and a wastewater tank 2. The base station body 101 includes a base assembly 102, which serves as a carrier for the lawnmower to dock and be cleaned. The water supply system 111 is a core spray water supply structure that uses a water pump 112, a three-way pipe 113, and a valve assembly 114 in conjunction with a first cleaning assembly 115 and a second cleaning assembly 116 to achieve differentiated cleaning. The base assembly 102 has a waste collection port 1020, which is connected to the liquid circulation tank assembly 1 and the wastewater tank 2 in sequence to form a wastewater recycling and purification loop. The purified water can be returned to the water supply end for recycling, or it can be supplied with clean water by an independent water tank. The entire structure works together to complete the fully automatic cleaning operation of the lawnmower.

[0054] When the lawnmower base station is operating, the cleaning water first flows into the water supply pump 112. After being pressurized by the water supply pump 112, it is sent to the three-way pipe 113 to complete the water diversion. The diverted water flows through the valve assembly 114 of their respective branches. The valve assembly 114 regulates the water flow and pressure before delivering it to the first cleaning assembly 115 and the second cleaning assembly 116 for spraying, completing the lawnmower spray cleaning. The wastewater after cleaning, carrying grass clippings and mud, flows out from the waste collection port 1020 and enters the liquid circulation tank assembly 1 and the wastewater tank 2 in sequence for impurity filtration and water purification. The purified water flows back to the inlet of the water supply pump 112 and re-enters the water circuit to participate in the cleaning operation, forming a complete closed-loop water circuit of water intake - pressurization and diversion - spray cleaning - wastewater recovery - purification and reuse. This water circuit has graded flow control and recycling, which can output water flow with different rinsing intensities as needed to meet cleaning requirements, while minimizing clean water loss.

[0055] With the above-described configuration, this application achieves the following technical effects: 1. The dual sets of cleaning components with different parameters, combined with a multi-angle spray layout, can thoroughly clean all parts of the lawnmower without dead angles, making the removal of stubborn stains more thorough and effectively improving the poor performance of traditional single-spray cleaning.

[0056] 2. The electronically controlled valve body can flexibly adjust the water outlet opening, match the cleaning intensity as needed, reduce ineffective water spraying loss, and significantly reduce daily water consumption.

[0057] 3. The wastewater recycling and purification cycle structure can realize the reuse of water resources, save clean water resources, avoid water waste, and make the use more energy-efficient and environmentally friendly.

[0058] 4. The concealed integrated layout of water system components makes the equipment structure compact and stable, and not easily damaged. At the same time, the water supply mode with built-in water tank is suitable for a variety of outdoor sites, making it more widely applicable.

[0059] 5. It can automatically complete the entire process of parking, cleaning, and wastewater collection without human intervention, achieving high efficiency in intelligent maintenance and adapting to routine maintenance operations for large lawns.

[0060] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this application should be included within the protection scope of this application.
