[0004] This application provides the following technical solution: In a first aspect, embodiments of this application provide a lawnmower cleaning base station, the cleaning base station comprising: case; An air source assembly is disposed in the housing. The air source assembly includes an air tank and an air compressor. The air inlet of the air tank and the exhaust port of the air compressor are connected. A purging assembly is disposed in the housing. The purging assembly has a purging inlet and a purging outlet that are connected to each other. The purging inlet of the purging assembly is connected to the outlet of the gas tank.

[0005] In some embodiments of the first aspect, the cleaning base station further includes a control component, the control component including a pressure sensor and a controller, the signal input terminal of the controller being electrically connected to the signal output terminal of the pressure sensor, the signal output terminal of the controller being electrically connected to the signal input terminal of the air compressor, and the pressure sensor being disposed on the air tank to detect the air pressure of the air tank; The controller is configured to start the air compressor when the air pressure is lower than a first preset threshold. The controller is also configured to control the air compressor to stop operating when the air pressure is higher than a second set threshold; wherein the first set threshold is equal to or less than the second set threshold.

[0006] In some embodiments of the first aspect, the cleaning base station further includes a cleaning station, and the control component further includes a position sensor disposed near the cleaning station, the position sensor being triggerable by a lawnmower moved to the cleaning station.

[0007] In some embodiments of the first aspect, the control component further includes a switching valve disposed at the gas outlet of the gas tank to control the opening and closing of the corresponding gas outlet.

[0008] In some embodiments of the first aspect, the switching valve is a control valve, the signal output terminal of the position sensor is electrically connected to the signal input terminal of the controller, and the signal input terminal of the control valve is electrically connected to the signal output terminal of the controller; when the position sensor is triggered and the gas pressure of the gas tank meets the first set threshold, the controller controls the control valve to open the gas outlet of the gas tank.

[0009] In some embodiments of the first aspect, the number of gas cylinders is N, and the gas cylinders are arranged in series. The air inlet of the first gas cylinder is connected to the exhaust port of the air compressor. The air inlet of the purging assembly is connected to the air outlet of the Nth gas cylinder, and satisfies: N≥2, where N is a positive integer.

[0010] In some embodiments of the first aspect, the number of purging components is at least two, the number of air outlets of the Nth gas tank is at least two, the air outlets of the Nth gas tank are spaced apart, and the air outlets of the Nth gas tank are respectively connected to the purging air inlet of the corresponding purging component.

[0011] In some embodiments of the first aspect, the cleaning base station further has a cleaning station, wherein when the lawnmower is located at the cleaning station, the blowing outlets of each of the blowing components are directed toward different areas of the bottom of the lawnmower.

[0012] In some embodiments of the first aspect, the housing includes a bearing surface located at the cleaning station, the bearing surface being used to support the lawnmower; Each of the aforementioned cleaning base stations also includes a waste recycling component, which includes a recycling bin and a bin door. The recycling bin has a feed inlet, and the bin door is configured to be openable and closable at the feed inlet. Among the various purge air outlets, at least one of the purge air outlets is a first purge air outlet. Each first purge air outlet is located on one side of the cleaning station, and the purge area of ​​each first purge air outlet together covers the cleaning station and faces the feed inlet located on the other side of the cleaning station, so as to blow the garbage toward the feed inlet.

[0013] Secondly, this application also provides a lawnmower cleaning system, which includes a lawnmower and a cleaning base station as described in any of the above embodiments. When cleaning the lawnmower, the blowing air outlet of the blowing assembly faces the bottom of the lawnmower.

[0014] The embodiments of this application have the following advantages: This application provides a cleaning base station. When the air compressor is running, it compresses external air and delivers it to an air tank for storage, forming a stable high-pressure air source. When the lawnmower enters the cleaning base station, the high-pressure gas stored in the air tank flows through the tank's outlet to the blowing inlet of the blowing assembly. After being accelerated by the blowing assembly, the high-pressure gas is ejected at high speed from its blowing outlet, forming a strong airflow that impacts the lawnmower chassis, effectively removing grass clippings, dirt, and other debris adhering to the chassis.

[0015] Therefore, high-pressure airflow can quickly remove accumulated grass clippings from the lawnmower chassis, significantly reducing labor intensity and saving maintenance time and labor costs. During breaks in operation, the lawnmower can quickly return to the base station to complete chassis cleaning, reducing efficiency losses caused by grass clippings and ensuring long-term high-efficiency operation. Furthermore, the air compressor generates high-pressure gas, which is delivered to the air tank to store energy, converting unstable airflow into stable high-pressure potential energy and preparing a powerful instantaneous impact force. During cleaning, the stable high-pressure gas stored in the air tank is distributed to the purging components, forming a uniform and highly impactful airflow. The air tank releases a stable high-pressure airflow, effectively breaking down and peeling away stubborn, hardened dirt. Additionally, the air compressor can operate intermittently, utilizing stored energy for operation, resulting in higher energy efficiency.

[0025] As shown in Figure 1, Figure 2 and Figure 3 As shown, to solve the above-mentioned technical problems, this application provides a lawnmower cleaning base station. The cleaning base station includes a housing 500, an air source component 400, and a blowing component 200. The air source component 400 is disposed in the housing 500 and includes an air tank 410 and an air compressor 420. The air inlet of the air tank 410 and the exhaust port of the air compressor 420 are connected. The blowing component 200 is disposed in the housing 500 and has a connected blowing inlet and a blowing outlet 210. The blowing inlet of the blowing component 200 is connected to the air outlet 411 of the air tank 410.

[0026] In these embodiments, the housing 500 is an integral frame structure, such as made of stainless steel or engineering plastic, with sufficient mechanical strength to support the internal components, and has an opening area for the lawnmower to drive into.

[0027] The air supply assembly 400 is fixedly installed inside the housing 500 and includes an air compressor 420 and an air tank 410. The air compressor 420 has its air inlet open to the outside atmosphere, and its exhaust port is sealed to the air inlet of the air tank 410 via a high-pressure hose. The air tank 410 is a pressure-resistant container and may be equipped with a pressure sensor and a safety valve inside for monitoring and controlling the air pressure inside the tank.

[0028] The blowing assembly 200 is located in the bottom area of ​​the housing 500, directly below the lawnmower chassis. For example, the blowing assembly 200 includes multiple nozzles arranged side-by-side, interconnected via a main pipe to form a unified blowing inlet and multiple blowing outlets 210. The blowing inlet is connected to the outlet 411 of the air tank 410 via another high-pressure pipeline. The nozzles exit upwards at a certain angle to ensure that the high-speed airflow effectively impacts different areas of the lawnmower chassis, including areas prone to grass accumulation such as the blade disc and wheel axle gaps.

[0029] The working process is as follows: After the lawnmower completes one round of work, it is automatically or manually guided into the housing 500 of the cleaning base station and parked in the preset position (which can be confirmed by positioning blocks or photoelectric sensors). At this time, the control system (which can be integrated into the base station or the lawnmower) triggers the cleaning program.

[0030] First, if the air pressure inside the air tank 410 is lower than the set threshold, the air compressor 420 starts, compresses ambient air, and delivers it to the air tank 410 for storage until the target pressure is reached, at which point it stops. This process can be completed in advance during lawnmower operation, enabling energy storage for later use.

[0031] Subsequently, the solenoid valve (not shown) of the gas tank 410 opens, and high-pressure gas flows out from the gas outlet 411 of the tank, enters the purge inlet of the purge assembly 200 through the high-pressure pipeline, and is quickly distributed to each nozzle. Since the outlet cross-sectional area of ​​the nozzle is much smaller than that of the inlet pipeline, the gas is accelerated here, forming a high-speed jet, which is sprayed upward from the purge outlet 210.

[0032] The high-speed airflow directly impacts the surface of the lawnmower chassis, instantly stripping and scattering attached grass clippings, wet mud, broken leaves, and other debris. The blown-off debris can be cleaned periodically or collected further by connecting a negative pressure vacuum system.

[0033] The entire blowing process effectively removes debris from the chassis, significantly outperforming traditional manual scrubbing methods. The entire cleaning process requires no human intervention, is time-efficient, and highly effective.

[0034] In another embodiment, the nozzle of the blowing assembly 200 is designed with an adjustable angle and is driven by a servo motor. It can automatically adjust the spray direction according to the chassis structure of different lawnmower models to improve cleaning coverage.

[0035] In addition, an image recognition module, such as a camera working in conjunction with a controller, can be added inside the housing 500 to determine the degree of dirt on the chassis by recognizing the image and to intelligently adjust the blowing time and air pressure to avoid energy waste.

[0036] In some embodiments, the clean base station also includes a control component, which includes a pressure sensor and a controller. The signal input terminal of the controller is electrically connected to the signal output terminal of the pressure sensor, and the signal output terminal of the controller is electrically connected to the signal input terminal of the air compressor 420. The pressure sensor is disposed in the air tank 410 to detect the air pressure of the air tank 410.

[0037] The controller is configured to start the air compressor 420 when the air pressure is lower than a first set threshold.

[0038] The controller is also configured to stop the air compressor 420 from operating when the air pressure is higher than a second set threshold; wherein the first set threshold is equal to or less than the second set threshold.

[0039] In some embodiments, a pressure sensor is installed inside the gas tank 410 or connected to the vicinity of the gas outlet 411 of the tank via a pipeline, for real-time monitoring of the gas pressure inside the gas tank 410 and outputting its detection signal to the controller.

[0040] For example, the controller can be a microcontroller, PLC, or embedded microcontroller, and its signal input terminal is electrically connected to the signal output terminal of the air pressure sensor. At the same time, the signal output terminal of the controller is electrically connected to the control terminal (i.e., signal input terminal) of the air compressor 420, thereby realizing automatic control of the start and stop of the air compressor 420.

[0041] Specifically, the controller has two preset pressure thresholds: a first preset threshold P1 and a second preset threshold P2, where P1 ≤ P2.

[0042] The controller is configured to execute the following control logic: When the pressure sensor detects that the actual pressure inside the air tank 410 is lower than the first set threshold P1, the controller outputs a start signal to control the air compressor 420 to start running and fill the air tank 410 with air. When the pressure sensor detects that the actual pressure inside the air tank 410 is higher than the second set threshold P2, the controller outputs a stop signal to stop the air compressor 420 from running.

[0043] The aforementioned hysteresis control strategy can effectively prevent the air compressor 420 from frequently starting and stopping near the pressure critical point, extend the equipment life, reduce operating noise, and ensure that the air tank 410 is always maintained in the usable high pressure range, providing a stable air source for purging operations.

[0044] Furthermore, when the lawnmower enters the cleaning station and triggers the cleaning command, if the current air pressure in the air tank 410 is already higher than P1, there is no need to wait for refilling; the purge solenoid valve can be opened immediately for cleaning, further improving the response speed. During non-operational periods, the system can maintain a low-power standby state, only briefly starting the compressor when the air pressure is insufficient, achieving energy-saving operation.

[0045] In some embodiments, the cleaning base station also has a cleaning station, and the control components also include a position sensor located near the cleaning station, which can be triggered by a lawnmower moved to the cleaning station.

[0046] In these embodiments, the cleaning station is a specific area pre-defined within the housing 500, used to guide or position the lawnmower so that its chassis is positioned directly above the blowing assembly 200, ensuring that the high-pressure airflow can accurately cover the area to be cleaned.

[0047] Furthermore, the control components also include a position sensor. The position sensor is installed in the perimeter of the cleaning station, such as embedded in the ground, fixed to a side wall, or located at the entrance, with its sensing surface facing the path of the lawnmower. For example, the position sensor may be an infrared beam sensor, an ultrasonic sensor, a microswitch, a Hall effect sensor (in conjunction with a magnet on the lawnmower), or a photoelectric switch.

[0048] When the lawnmower moves into the cleaning station and reaches the cleaning position, its body or chassis structure triggers the position sensor, for example, by blocking the infrared beam, approaching the Hall element, or pressing a mechanical switch. Once triggered, the position sensor outputs a positioning signal to the controller. Upon receiving this signal, the controller performs the cleaning operation described above, which will not be elaborated further.

[0049] By integrating position sensors with the cleaning stations, the system enables fully automated, trigger-based cleaning without manual intervention or additional commands. It also prevents accidental activation of the sweeping mechanism before the lawnmower is in position, thus avoiding energy waste or ineffective cleaning.

[0050] In one embodiment, the cleaning station is equipped with a physical limit block. When the front wheel of the lawnmower comes into contact with the block, it is considered to be accurately positioned. At this time, the position sensor is triggered synchronously, providing double protection for positioning reliability.

[0051] In another embodiment, multiple position sensors are arranged at the front, back, left, and right sides of the cleaning station to determine whether the lawnmower has fully entered and is centered, thereby improving cleaning coverage and safety.

[0052] In some embodiments, the control component further includes a switching valve disposed at the gas outlet 411 of the gas tank 410 to control the opening and closing of the corresponding gas outlet 411.

[0053] In these embodiments, a switching valve is installed at the gas outlet 411 of the gas tank 410 to control whether high-pressure gas flows from the gas tank 410 to the purging assembly 200.

[0054] The switching valve can be a solenoid valve, pneumatic valve, or electro-proportional valve. For example, a normally closed two-position two-way solenoid valve is selected, which is closed by default and only turns on when it receives an opening command from the controller.

[0055] The control terminal of the switching valve is electrically connected to the signal output terminal of the controller. The controller controls the opening and closing of the switching valve according to preset logic, specifically including the following operating modes: Standby mode: When no lawnmower enters or no cleaning command is triggered, the switch valve remains closed, so that even if the gas tank 410 contains high-pressure gas, it will not leak into the blow-off assembly 200, thereby reducing gas consumption and improving safety.

[0056] Cleaning execution status: When the position sensor detects that the lawnmower has arrived and the controller confirms that the air pressure in the air tank 410 meets the cleaning conditions, the controller outputs a control signal.

[0057] By setting up the switching valve, not only is precise timing control of the high-pressure airflow achieved, but pressure drops caused by minor leaks in the pipeline or misoperation are also effectively avoided, ensuring the reliability of the next cleaning operation. Furthermore, when maintaining or repairing the purging assembly 200, the switching valve can be forcibly closed via the controller to isolate the air path and improve operational safety.

[0058] In a variant embodiment, the switching valve is respectively set to correspond to multiple branches of the purging assembly 200, that is, each nozzle group is equipped with an independent switching valve. The controller can selectively open some nozzles according to the lawnmower model or the dirty area to realize zoned purging on demand, further saving energy and reducing consumption.

[0059] In some embodiments, the switching valve is a control valve, the signal output terminal of the position sensor is electrically connected to the signal input terminal of the controller, and the signal input terminal of the control valve is electrically connected to the signal output terminal of the controller; when the position sensor is triggered and the air pressure of the gas tank 410 meets the first set threshold, the controller controls the control valve to open the gas outlet 411 of the gas tank 410.

[0060] In these embodiments, the switching valve in the control component is specifically a control valve, such as an electrically controlled normally closed solenoid valve, whose function is not limited to on / off switching, but also serves as a key actuator for cleaning execution and is regulated by the controller.

[0061] Specifically, the signal output terminal of the position sensor is electrically connected to the signal input terminal of the controller, and is used to provide real-time feedback to the controller on whether the lawnmower has moved to the cleaning position. At the same time, the signal input terminal of the control valve is electrically connected to the signal output terminal of the controller, and receives the controller's opening or closing commands.

[0062] In some embodiments, there are N gas cylinders 410, which are connected in series. The air inlet of the first gas cylinder 410 is connected to the exhaust port of the air compressor 420. The air inlet of the purging assembly 200 is connected to the air outlet 411 of the Nth gas cylinder 410, and satisfies: N≥2, where N is a positive integer.

[0063] In these embodiments, the gas tanks 410 are connected in series along the gas flow direction to form a multi-stage gas storage unit. The specific connection relationship is as follows: The air inlet of the first gas tank 410 is connected to the exhaust port of the air compressor 420 via a high-pressure pipeline. The air outlet 411 of the first gas tank 410 is connected to the air inlet of the second gas tank 410. The air outlet 411 of the second gas tank 410 is connected to the air inlet of the third gas tank 410. And so on, until the Nth gas tank. The outlet 411 of one gas tank 410 is connected to the inlet of the Nth gas tank 410. Finally, the purge inlet of the purge assembly 200 is connected to the outlet 411 of the Nth gas tank 410.

[0064] Through the above-described series structure, after the high-pressure gas is discharged from the air compressor 420, it flows sequentially through the first to the Nth gas tanks 410, and finally outputs from the Nth gas tank 410 to the purging assembly 200.

[0065] As the gas passes through multiple gas tanks 410 in stages, the turbulence is reduced and the pressure fluctuations are absorbed, making the airflow that is finally output to the purging assembly 200 more stable and uniform. This helps to form a consistent purging effect and avoids nozzle wear or uneven cleaning caused by instantaneous pressure spikes.

[0066] Connecting multiple gas tanks 410 in series can significantly increase the total effective volume of the system, providing a more sufficient reserve of high-pressure gas without increasing the pressure of a single tank, to meet the needs of long-term continuous operation or rapid rotation cleaning of multiple lawnmowers.

[0067] Users can flexibly choose N=2, 3 or more based on the actual cleaning frequency and the number of lawnmowers to achieve on-demand customization of base station configuration.

[0068] In addition, the pressure sensor in the control assembly can be set inside the Nth gas tank 410 or near its outlet to accurately monitor the actual pressure supplied to the purging assembly 200, ensuring that the control logic makes judgments based on the actual available pressure.

[0069] In some embodiments, the number of purging components 200 is at least two, the number of canister outlets 411 of the Nth gas canister 410 is at least two, the canister outlets 411 of the Nth gas canister 410 are spaced apart, and the canister outlets 411 of the Nth gas canister 410 are respectively connected to the purging inlet of the corresponding purging component 200.

[0070] In these embodiments, the number of purging components 200 in the cleaning base station is at least two, including, for example, a first purging component 200 and a second purging component 200. Correspondingly, the number of canister outlets 411 of the Nth gas canister 410 is also at least two, including a first canister outlet 411, a second canister outlet 411, etc.

[0071] Each tank outlet 411 is spaced apart on the tank body of the Nth tank 410, for example, evenly distributed along the circumference or axis of the tank body, maintaining a certain physical distance from each other, so as to avoid airflow interference and facilitate pipeline layout.

[0072] Furthermore, each outlet 411 of the Nth gas tank 410 is connected to the purge inlet of the corresponding purge assembly 200. Specifically, the first outlet 411 is connected to the purge inlet of the first purge assembly 200 via a first high-pressure pipeline. The second outlet 411 is connected to the purge inlet of the second purge assembly 200 via a second high-pressure pipeline. If there are more purge assemblies 200, this process continues.

[0073] In addition, each blowing assembly 200 can be independently arranged in different areas within the housing 500. For example, the first blowing assembly 200 is located at the front of the cleaning station and is used to clean the area in front of the lawnmower's front wheels and blade head. The second blowing assembly 200 is located at the rear of the cleaning station and is used to clean the rear wheels and the rear of the chassis.

[0074] In some embodiments, the cleaning base station also has a cleaning station, in which the blowing outlets 210 of each blowing assembly 200 are directed toward different areas of the bottom of the lawnmower when the lawnmower is in the cleaning station.

[0075] In these embodiments, the cleaning station is used to guide the lawnmower to a preset position. When the lawnmower is in the cleaning station, the blow outlets 210 of each blow assembly 200 are directed toward different areas on the bottom of the lawnmower to achieve targeted cleaning of the chassis.

[0076] The position, angle, and jet direction of each purge outlet 210 can be set as needed to ensure that the high-speed airflow can effectively impact the target area, while avoiding mutual interference of airflows or energy waste.

[0077] In some embodiments, the housing 500 includes a bearing surface 100 located at the cleaning station and used to support a lawnmower. Each cleaning station also includes a waste collection assembly 300, which includes a collection bin 320 and a bin door 310. The collection bin 320 has a feed inlet 321, and the bin door 310 is closable at the feed inlet 321. At least one of the purge outlets 210 is a first purge outlet 211. Each first purge outlet 211 is located on one side of the cleaning station, and the purge area of ​​each first purge outlet 211 collectively covers the cleaning station and faces the feed inlet 321 located on the other side of the cleaning station, so as to blow waste towards the feed inlet 321.

[0078] In these embodiments, the bottom of the housing 500 is provided with a bearing surface 100, which is located within the cleaning station 5 and is used to directly support the wheels or chassis support of the lawnmower. The bearing surface 100 may be made of wear-resistant steel plate, anti-slip grating or high-strength engineering plastic, and the surface is flat to ensure stable parking of the lawnmower and facilitate the sliding off of debris.

[0079] Furthermore, the cleaning station also includes a waste recycling assembly 300. A recycling bin 320 is located inside the housing 500 or on one side of the bottom, and has an inlet 321 facing the cleaning station. A bin door 310 is installed at the inlet 321 in an openable manner, for example, by a hinge and equipped with an electric push rod or a manual pull handle, for opening when needed to clean up accumulated grass clippings, dirt, and other waste inside the bin, and keeping it closed at other times to prevent dust or foreign objects from entering.

[0080] Crucially, in this embodiment, at least one of the purge outlets 210 is configured as a first purge outlet 211. All first purge outlets 211 are located on one side of the cleaning station, such as the front side, while the feed inlet 321 of the recovery bin 320 is located on the opposite side of the cleaning station, such as the rear side.

[0081] The airflow path of each first purge outlet 211 spans the entire cleaning station, and the purging area together covers all or most of the bearing surface 100. The airflow eventually converges and points towards the feed inlet 321.

[0082] Thus, when high-pressure gas is ejected at high speed from the first blow-out port 211, it can not only peel off the attached materials on the lawnmower chassis, but also push the blown grass clippings, broken leaves, mud clods, etc. along the bearing surface 100 to the feed inlet 321 of the recycling bin 320, and enter the recycling bin 320 under the guidance of the airflow to realize the clipping collection function.

[0083] In one embodiment, the cleaning station is rectangular, with the bearing surface 100 set horizontally. The recycling bin 320 is located at the rear end of the cleaning station, the feed inlet 321 is open to the front, and two first purge air outlets 211 are symmetrically arranged on the left and right front sides of the cleaning station. The nozzle angle is adjusted to tilt backward, and the airflow forms a confluence area above the bearing surface 100, which pushes the debris to the rear feed inlet 321.

[0084] In addition, the bearing surface 100 can be designed as a slightly tilted structure, using gravity to assist the waste to slide down into the feed inlet 321, further improving recycling efficiency.

[0085] The combination of the waste recycling component 300 and the directional purging design creates a closed-loop, spill-free, and easy-to-maintain cleaning process. Users only need to periodically open the compartment door 310 to empty the recycling compartment 320 to complete waste disposal, significantly reducing the frequency of manual intervention.

[0086] In some embodiments, this application also provides a lawnmower cleaning system, which includes a lawnmower and a cleaning base station as described in any of the above embodiments. When cleaning the lawnmower, the blowing outlet 210 of the blowing assembly 200 faces the bottom of the lawnmower.

[0087] In these embodiments, the lawnmower is an autonomous or remote-controlled intelligent lawnmower equipped with a navigation module (such as GPS, visual SLAM, or magnetic strip guidance), an operation status monitoring unit, and a communication interface. After completing a preset task, it can return to the cleaning base station for chassis maintenance.

[0088] When performing a cleaning operation, the lawnmower drives into and parks at the cleaning station's cleaning position, with its chassis facing the blowing assembly 200. At this time, as mentioned earlier, the blowing outlets 210 of the blowing assembly 200 all face the bottom of the lawnmower, ensuring that the high-speed airflow directly acts on areas prone to grass accumulation. After cleaning is completed, the lawnmower can continue operating.

[0089] This lawnmower cleaning system achieves closed-loop operation and maintenance, maintaining the lawnmower's long-term efficient operation without manual intervention. It is especially suitable for scenarios requiring multi-machine collaboration and high-frequency operation, such as large gardens, golf courses, and smart parks.

[0090] In one embodiment, the lawnmower and the cleaning base station exchange status information, such as battery level, operating time, and chassis dirt level, via wireless communication (e.g., Wi-Fi, Bluetooth, or LoRa). The base station dynamically adjusts the blowing intensity and duration accordingly to achieve on-demand cleaning.

[0091] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0092] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0093] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
