Base station, lawnmower and lawnmower lens cleaning system and method

Abstract

This invention provides a base station, a lawnmower, and a lawnmower lens cleaning system and method. The base station includes a base station body and a spraying mechanism. The base station body has a parking area for parking the lawnmower. The spraying mechanism is disposed on the base station body and includes a spray head. The spray head is located above the parking area and is mounted on the base station body via a support structure. The spray head has a water nozzle facing the parking area. When the lawnmower is parked in the parking area, the water nozzle is directed towards the lawnmower's sensor lens. When the lawnmower enters the base station and parks in the parking area, the base station's spray head can spray water or a special cleaning solution towards the lawnmower's sensor lens, softening or liquefying the dirt on the sensor lens surface. This significantly reduces the friction of the dirt on the sensor lens surface, preventing excessive wear from the lawnmower's brushes when cleaning the sensor lens surface, thus providing good protection for the sensor lens.

Description

Technical Field

[0001] This application relates to the field of lawnmower cleaning technology, and more particularly to a base station, a lawnmower, and a lawnmower lens cleaning system and method. Background Technology

[0002] When current lawnmower robots operate outdoors, their vision lenses are prone to accumulating contaminants such as grass clippings, mud, and grass juice. Traditional cleaning solutions often employ a single wiper structure, which presents the following problems: Severe physical wear: Dry, hard particles create a "sandpaper effect" when the wipers are used, abrading the lens's anti-reflective coating and causing a 15% decrease in light transmittance. 20%, affecting the accuracy of visual recognition. Incomplete cleaning: Sticky stains cannot be completely removed by mechanical scraping, leaving a fog-like residue that can easily lead to misjudgment of images.

[0003] The robot's built-in cleaning system has limitations: due to limited space, small water storage capacity, and low water pump power, the cleaning effect is poor, and frequent water filling and maintenance are inconvenient. Summary of the Invention

[0004] The purpose of this invention is to at least overcome the technical problem in the prior art where dry, hard particles cause damage to the lens during windshield wiper operation. A base station, a lawnmower, and a lawnmower lens cleaning system and method are provided.

[0005] This application provides a base station comprising a base station body and a sprinkler mechanism. The base station body has a parking area for parking a lawnmower. The sprinkler mechanism is disposed on the base station body and includes a spray head located above the parking area and supported by a support structure on the base station body. The spray head has a water nozzle facing the parking area. When the lawnmower is parked in the parking area, the water nozzle is positioned towards the lawnmower's sensor lens.

[0006] In some embodiments, the base station is provided with a cleaning fluid storage tank and / or a water source connection component for connecting to an external water source; The spray head is connected to the cleaning fluid storage tank and / or the water source connection.

[0007] In some embodiments, the spraying mechanism further includes a water pump in communication with the spray head, the water pump being connected to the cleaning fluid storage tank and / or the water source connection.

[0008] In some embodiments, the spray head is provided with a water flow channel communicating with the spray nozzle. When water is sprayed from the spray head, the inner diameter of the water flow channel gradually decreases or decreases in stages to form a pressurization structure.

[0009] This application provides a lawnmower comprising a lawnmower body and a wiper mechanism. The lawnmower body has a sensor lens, and when the lawnmower body is parked in the parking area of ​​the aforementioned base station, the sensor lens faces the spray head. The wiper mechanism is disposed on the lawnmower body and close to the sensor lens. The wiper mechanism includes a brush body for cleaning the sensor lens and a drive assembly for driving the brush body to move. The brush body can move in contact with the sensor lens to clean it.

[0010] In some embodiments, the drive assembly has a drive motor, one end of the brush body is connected to the output of the drive motor, and the drive motor drives the brush body to oscillate.

[0011] In some embodiments, the wiper mechanism further includes a clamping assembly for pressing the brush body against the sensing lens, the clamping assembly being connected to the output end of the drive motor or to the lawnmower body, and elastically abutting against the brush body.

[0012] In some embodiments, the brush body is provided with a sleeve hole, and the brush body is sleeved on the output end of the drive motor through the sleeve hole; The clamping assembly includes an elastic element and a clamping screw. The clamping screw is threadedly connected to the output end of the drive motor. The elastic element elastically abuts against the clamping screw and the brush body to maintain the brush body pressing against the sensing lens.

[0013] This application provides a lawnmower lens cleaning system comprising a base station and a lawnmower. When the lawnmower is parked in the parking area of ​​the base station, the spray head of the base station is positioned towards the sensing lens of the lawnmower. The lawnmower lens cleaning system further includes a control module, a sensing module, a first control component disposed on the lawnmower, and a second control component disposed on the base station. The control module is disposed on the base station, and the second control component is electrically connected to the control module and the water pump. The sensing module is electrically connected to the control module and has a sensing end for sensing the position of the lawnmower, the sensing end being positioned relative to the parking area. The first control component is electrically connected to the drive assembly, and the first control component is wirelessly connected to the control module.

[0014] This application provides a lawnmower lens cleaning method using the aforementioned lawnmower lens cleaning system, the lawnmower lens cleaning method comprising: S1. Park the lawnmower in the parking area by means of a predetermined program or manually; S2. The spraying mechanism is activated, causing the spray head to spray water or cleaning fluid toward the sensing lens to rinse and wet the sensing lens. S3. The driving component drives the brush body to reciprocate against the sensing lens to clean the sensing lens.

[0015] The present invention provides a base station where, after a lawnmower has completed its mowing operation or a phase of operation, it can drive into the base station and park in the designated parking area. At this time, the spray head in the sprinkler mechanism, positioned towards the lawnmower's sensor lens, can spray water or a special cleaning solution onto the sensor lens. This wets and softens or liquefies dirt, mud, and other foreign matter adhering to the sensor lens surface. Then, when the brush body in the lawnmower's wiper mechanism, located near the sensor lens, brushes the sensor lens, the dirt on the sensor lens surface is softened or liquefied by the water or special cleaning solution sprayed from the spray head. The brush body can easily brush off the dirt and greatly reduce the friction between the dirt and the sensor lens surface. This prevents the brush body from causing significant wear to the sensor lens surface due to dry brushing, thus providing good protection for the sensor lens and facilitating the mower's mowing and cleaning maintenance.

For example, different implementation methods can be formed by combining different specific technical features / embodiments. In order to avoid unnecessary repetition, the various possible combinations of the various specific technical features / embodiments in this invention will not be described separately.

[0023] like Figure 1 , Figure 2 and Figure 3 , Figure 4 As shown in the figure, an embodiment of the present invention provides a lawnmower lens cleaning system including a lawnmower 100 and a base station 200.

[0024] The aforementioned base station 200 includes a base station body 21 and a sprinkler mechanism 22. The base station body 21 has a parking area 201 for parking the lawnmower 100. The sprinkler mechanism 22 is disposed on the base station body 21 and includes a spray head 221. The spray head 221 is located above the parking area 201 and is disposed on the base station body 21 by a support structure. The spray head 221 has a water nozzle 01 facing the parking area 201. When the lawnmower 100 is parked in the parking area 201, the water nozzle 01 is positioned facing the sensor lens 111 of the lawnmower 100.

[0025] The lawnmower 100 includes a lawnmower body 11 and a wiper mechanism 12. The lawnmower body 11 has a sensor lens 111 and can be parked in the parking area 201 of the base station 200. When the lawnmower 100 is parked in the base station 200, the sensor lens 111 of the lawnmower 100 is positioned towards the spray head 221. The wiper mechanism 12 is disposed on the lawnmower body 11 and is located close to the sensor lens 111. The wiper mechanism 12 includes a brush body 121 for cleaning the sensor lens 111 and a drive assembly 122 for driving the brush body 121. The brush body 121 can move in contact with the sensor lens 111 to clean the sensor lens 111.

[0026] In practical applications, the aforementioned base station 200 can be a charging and cleaning integrated base station used for charging and cleaning the lawnmower 100. The aforementioned sensor lens 111 is typically mounted on the top of the lawnmower 100 to identify its operating environment, allowing the lawnmower 100 to identify its working range and avoid obstacles during operation. The sensor lens 111 can also be used to identify the specific location of the base station 200, enabling the lawnmower 100 to accurately enter the base station 200 for cleaning, charging, and other operations. From the above description, it is clear that the aforementioned sensor lens 111 plays a crucial role in the mowing and cleaning maintenance of the lawnmower 100. With the above design, after the lawnmower 100 finishes mowing or completes a phase of work, the lawnmower 100 can drive into the base station 200 and park in the parking area 201 of the base station 200. At this time, the spray head 221 of the spray mechanism 22 facing the sensor lens 111 of the lawnmower 100 can spray water or special cleaning fluid onto the sensor lens 111, so that the stains, dirt and other foreign objects attached to the surface of the sensor lens 111 are moistened and become soft or liquefied. Then, the brush body 121 of the wiper mechanism 12 located near the sensor lens 111 can move against the surface of the sensor lens 111 under the drive of the drive component 122 to perform a brushing operation on the sensor lens 111. Before the brushing operation, the stains on the surface of the sensor lens 111 have been softened or liquefied by the water or special cleaning solution sprayed from the spray head 221. The brush body 121 can easily brush off the stains and greatly reduce the friction of the stains on the surface of the sensor lens 111. This prevents the brush body 121 from causing significant wear on the surface of the sensor lens 111 due to dry brushing, thus providing good protection for the sensor lens 111 and facilitating the mowing and cleaning maintenance of the lawnmower 100.

[0027] In addition to the aforementioned beneficial effects, the lawnmower lens cleaning system provided in this application, by placing the spraying mechanism 22 on the base station 200, eliminates the need for a component in the lawnmower 100 to hold cleaning fluid or water, and also eliminates the need for a water channel structure inside the lawnmower 100, thus avoiding any risk to the internal circuitry of the lawnmower 100 from water channels. This improves the compactness and safety of the internal structure of the lawnmower 100.

[0028] In some embodiments, the spray head 221 is slidably or rotatably mounted on the base station body 21. Specifically, the support structure 23 may be a rotating mechanism (not shown in the figure), which has a rotating end. The spray head 221 is mounted on the rotating end and can rotate with the rotating end. The rotating mechanism may be driven by a motor to rotate, so that when the spray head 221 sprays liquid into the sensing lens 111 of the lawnmower 100, it can expand the spraying area of ​​the spray head 221 and change the angle and pressure of the liquid impacting the sensing lens 111 through its own rotation, which helps to improve the scouring and wetting effect of the spray head 221 on the sensing lens 111.

[0029] In some embodiments, base station 200 is provided with a cleaning fluid storage tank and / or a water source connection assembly for connecting to an external water source. Spray head 221 is also connected to the cleaning fluid storage tank and / or the water source connection assembly.

[0030] Preferably, the base station 200 is equipped with a cleaning fluid storage tank and a water source connection component for connecting to an external water source. The spray head 221 is connected to both the cleaning fluid storage tank and the water source connection component. In practical applications, the cleaning fluid storage tank is used to hold a dedicated cleaning fluid containing surfactants and other ingredients, which can quickly emulsify or decompose stains on the surface of the sensor lens 111 and accelerate the removal of stains from the sensor lens 111 compared to water. The water source connection component can specifically be a connector for connecting to an external tap water system. With the above design, the spray head 221 can spray both dedicated cleaning fluid and water. Thus, when the lawnmower 100 is parked in the parking area 201, the dedicated cleaning fluid can be sprayed onto the sensor lens 111 through the spray head 221 to make it easier for stains to detach from the surface of the sensor lens 111. Then, the sensor lens 111 can be brushed by the brush body 121, and finally, clean water can be sprayed through the spray head 221 to clean away any remaining cleaning fluid. The above process helps to further improve the cleaning effect on the sensor lens 111.

[0031] Furthermore, the base station 200 is also equipped with a clean water tank for storing clean water, a first solenoid valve, and a second solenoid valve. The clean water tank is connected to the spray head 221, and the water source connection component is connected to the clean water tank. The first solenoid valve is located between the cleaning fluid storage tank and the spray head to control the on / off connection between the spray head 221 and the cleaning fluid storage tank. The second solenoid valve is located between the clean water tank and the spray head 221 to control the on / off connection between the spray head 221 and the clean water tank. In practical applications, the clean water tank can be replenished with clean water through the water source connection component. When cleaning fluid needs to be sprayed, the first solenoid valve opens and the second solenoid valve closes; when clean water needs to be sprayed, the first solenoid valve closes and the second solenoid valve opens. With the above design, the sensor lens 111 can be cleaned with cleaning fluid first, and then the residual cleaning fluid on the sensor lens 111 can be cleaned with clean water. Because the cleaning solution has a stronger softening and liquefaction effect on stains than water, the above design allows the stains on the sensor lens 111 to be softened or liquefied more quickly, thus more effectively preventing the sensor lens 111 from being scratched when brushed by the brush body 121. Finally, the water cleaning solution improves the cleanliness of the sensor lens 111, which is beneficial for the mower 100's mowing and cleaning maintenance.

[0032] In some implementations, such as Figure 9 , Figure 10 As shown, the spraying mechanism 22 also includes a water pump 222 that is connected to the spray head 221, and the water pump 222 is connected to the cleaning liquid storage tank and / or water source connection.

[0033] Preferably, the water pump 222 is connected to the cleaning fluid storage tank and the water source connection assembly via a two-way connector (which has one inlet and two outlets, a common component in water circuit connections, and will not be described in detail here). The first solenoid valve is located in the pipeline between the cleaning fluid storage tank and the water pump 222, and the second solenoid valve is located in the pipeline between the water source connection assembly and the water pump 222. The connection between the water pump 222 and the cleaning fluid storage tank and the water source connection assembly can be controlled by the first and second solenoid valves, thereby controlling the spray head 221 to spray cleaning fluid or clean water. In some embodiments, the clean water tank is connected to both the water source connection assembly and the second solenoid valve. The water pump 222 obtains clean water from the clean water tank, and the water source connection assembly can replenish the clean water tank. In this way, the water tank can store clean water, allowing the base station 200 to clean the sensor lens 111 of the lawnmower 100 in places where it is inconvenient to connect to an external water source, and the cleaning process is less likely to scratch the sensor lens 111.

[0034] The above design integrates both the water tank and the cleaning solution storage tank into the base station 200, saving space inside the lawnmower 100 for cleaning components and reducing energy consumption. Details are as follows: In practical applications, the base station 200 is usually fixed in one location, which facilitates connection to an external power source and the installation of a water tank and cleaning solution storage tank, as well as easy access to an external water source. However, since the lawnmower 100 needs to move continuously, installing a cleaning solution storage tank or water tank would put a load on the movement of the lawnmower 100 and accelerate the energy consumption inside the lawnmower 100.

[0035] In some implementations, such as Figure 3 , Figure 4 and Figure 5 , Figure 6 As shown, the drive assembly 122 has a drive motor, and one end of the brush body 121 is connected to the output end of the drive motor. The drive motor drives the brush body 121 to swing. In practical applications, one end of the brush body 121 is connected to the output end of the drive motor, and the other end is a free end. When the drive motor drives it to swing, its side can come into contact with the surface of the sensing lens 111 to scrape and remove dirt from the surface of the sensing lens 111. In some embodiments, the scraping principle can be the same as that of common car windshield wipers. The brush body 121 can come into contact with the surface of the sensing lens 111 and reciprocate to repeatedly clean the sensing lens 111.

[0036] In some implementations, such as Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the wiper mechanism 12 also includes a clamping assembly 123 for pressing the brush body 121 against the sensor lens 111. The clamping assembly 123 is connected to the output end of the drive motor or to the lawnmower 100, and elastically abuts against the brush body 121. Through this design, the clamping assembly 123 allows the brush body 121 to continuously press against the sensor lens 111, ensuring that the side of the brush body 121 that is in contact with the sensor lens 111 remains firmly against the surface of the sensor lens 111 when wiping it, thus better cleaning the sensor lens 111. In addition to the above-mentioned beneficial effects, the close contact between the brush body 121 and the surface of the sensor lens 111 also prevents dirt and other foreign objects adhering to the surface of the sensor lens 111 from easily entering between the brush body 121 and the surface of the sensor lens 111, effectively preventing the sensor lens 111 from being scratched. In particular, when the sensor lens 111 is sprayed with cleaning liquid or water, the adhesion of foreign objects such as dirt on its surface is reduced. The brush body 121 can better scrape away foreign objects such as dirt by adhering closely to the surface of the sensor lens 111. At the same time, sand particles in the dirt are less likely to enter between the brush body 121 and the surface of the sensor lens 111. This improves the cleaning effect of the brush body 121 on the sensor lens 111 and also reduces the possibility of the sensor lens 111 being scratched.

[0037] Specifically, such as Figure 7 , Figure 8As shown, the brush body 121 is provided with a sleeve hole 04, through which the brush body 121 is sleeved onto the output end of the drive motor. The clamping assembly 123 includes an elastic element 1231 and a clamping screw 1232. The clamping screw 1232 is threadedly connected to the output end of the drive motor. The elastic element 1231 elastically abuts against the clamping screw 1232 and the brush body 121 to maintain the brush body 121 pressing against the sensing lens 111. In practical applications, the sleeve hole 04 is provided at one end near the brush body 121, and the sleeve hole 04 is not a circular hole, specifically a square hole; this arrangement can prevent the brush body 121 from slipping when rotating with the output end of the drive motor. Please refer to the figure. The drive motor is fixed relative to the sensing lens 111 (both the sensing lens 111 and the drive motor are fixed to the main body of the lawnmower 100), and a threaded hole is provided at the output end. The clamping screw 1232 is threadedly connected to the output end of the drive motor through this threaded hole. The connection direction between the clamping screw 1232 and the drive motor is perpendicular to the swing plane of the brush body 121. Please refer to the figure. Figure 8 The aforementioned elastic element 1231 can be a spring, with a diameter larger than the diameter of the sleeve hole 04 and smaller than the head diameter of the clamping screw 1232. When the clamping screw 1232 is connected to the output end of the drive motor, one end of the spring abuts against the head of the clamping screw 1232, and the other end abuts against the brush body 121. In this way, the spring can continuously apply a pressure towards the sensing lens 111 to the brush body 121, so that the brush body 121 can always keep in contact with the surface of the sensing lens 111 during the swinging process. In addition to the above-mentioned beneficial effects, it is understood that by rotating the clamping screw 1232, the distance between the head of the clamping screw 1232 and the brush body 121 can be changed, thereby changing the degree of spring compression, so that the holding force between the brush body 121 and the sensing lens 111 changes. In this way, the holding force between the brush body 121 and the sensing lens 111 can be adjusted by rotating the clamping screw 1232, so that the brush body 121 can better clean the sensing lens 111.

[0038] Furthermore, such as Figure 6 , Figure 7 , Figure 8 As shown, the brush body 121 includes a scraper arm 1211 and a scraping member 1212 connected to the scraper arm 1211. One end of the scraper arm 1211 is connected to the output end of the drive motor, and the other end is free. The scraping member 1212 is disposed on the side of the scraper arm 1211 near the sensing lens 111 and is used to press against the sensing lens 111. The side of the scraping member 1212 used to press against the sensing lens 111 is made of an elastic material, specifically rubber or silicone. When rubbing against the surface of the sensing lens 111, it can effectively scrape away dirt and other stains, while also avoiding hard contact with the sensing lens 111 and scratching it.

[0039] Understandably, in practical applications, the scraper 1212 will wear and age after prolonged use, reducing the cleaning effect of the brush body 121 on the sensor lens 111. To address this issue, the scraper 1212 is detachably connected to the scraper arm 1211. Specifically, the scraper arm 1211 has a slot 05 on the side opposite the sensor lens 111, into which the scraper 1212 is inserted and protrudes from the side of the scraper arm 1211 that is close to the sensor lens 111. With this design, when the scraper 1212 wears or ages, the brush body 121 can be removed from the output end of the drive motor, and the scraper 1212 can be quickly replaced. Because the scraper 1212 is pressed between the scraper arm 1211 and the sensor lens 111, the scraper 1212 will not come out of the slot 05.

[0040] In some implementations, such as Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown, the spray head 221 is provided with a water flow channel 02 that communicates with the water nozzle 01. The direction of water flow in the water flow channel 02 when the spray head 221 sprays water is along the direction of water flow when spraying water. Figure 12 In the X direction, the inner diameter of the water jet channel 02 gradually decreases or decreases in stages to form a pressurization structure. This design helps to increase the pressure of the liquid flow sprayed from the spray head 221, allowing the liquid flow to impact the surface of the sensing lens 111 with stronger pressure. This washes away large particles of foreign matter such as dirt adhering to the surface of the sensing lens 111, preventing these large particles from scratching the sensing lens 111 when the brush body 121 scrapes it later.

[0041] To enhance the wetting and rinsing effect of the spray head 221 on the sensor lens 111, the spraying mechanism 22 has multiple high-pressure spray heads for spraying high-pressure liquid streams and at least one atomizing spray head. Correspondingly, the spraying structure has two water pumps 222, one connected to the high-pressure spray head and the other connected to the atomizing spray head. With this design, when the lawnmower 100 is parked in the parking area 201 of the base station 200, cleaning liquid can first be sprayed through the atomizing spray head. After the cleaning liquid softens or liquefies the dirt and other stains on the surface of the sensor lens 111, high-pressure water streams are then sprayed through the high-pressure spray head to rinse the sensor lens 111. This operation significantly reduces the amount of dirt and other stains adhering to the surface of the sensor lens 111 before the brush body 121 performs the brushing operation, thereby reducing the possibility of the sensor lens 111 being scratched during brush body 121 brushing.

[0042] Specifically, the high-pressure spray head is connected to the clean water tank or water source connection assembly via a first pipeline, and the atomizing spray head is connected to the cleaning fluid storage tank via a second pipeline. Two water pumps 222 are respectively installed in the first and second pipelines. In practical applications, the cleaning fluid is typically a surfactant, primarily used to soften, liquefy, and dissolve dirt and other contaminants on the surface of the sensor lens 111. The liquid sprayed from the atomizing spray head is in a mist form, allowing for thorough and comprehensive application of the cleaning fluid to the surface of the sensor lens 111, minimizing dead zones. The high-pressure spray head primarily uses high-pressure liquid flow to wash away dirt and other contaminants from the surface of the sensor lens 111. However, it consumes a large amount of liquid during spraying, making it suitable for rinsing with clean water. Through this design, clean water and cleaning fluid are sprayed through spray heads with different functions, saving on cleaning fluid usage while ensuring effective cleaning of the sensor lens 111.

[0043] In some implementations, such as Figure 11 , Figure 12 As shown, the spray head 221 is also provided with a water flow dispersion structure 03 for transforming the shape of the water flow sprayed from the spray head 221 into a fan shape. The water flow dispersion structure 03 is connected to the water spray channel.

[0044] Specifically, the aforementioned water flow dispersion structure 03 can be a fan-shaped nozzle (a common structure in the art, which will not be described in detail here). This fan-shaped nozzle is disposed at the end of the spray head 221 where the water nozzle 01 is provided, and is connected to the water nozzle 01. The fan-shaped water flow can increase the rinsing area of ​​the spray head 221 on the sensing lens 111, which helps to reduce the amount of dirt and other stains adhering to the surface of the sensing lens 111, thereby reducing the possibility of the sensing lens 111 being scratched when brushed by the brush body 121.

[0045] In some embodiments, the lawnmower lens cleaning system provided in this application further includes a control module, a sensing module, a first control unit disposed on the lawnmower 100, and a second control unit disposed on the base station 200. The control module is disposed on the base station 200, and the second control unit is electrically connected to the control module and the water pump 222. The sensing module is electrically connected to the control module and has a sensing end for sensing the position of the lawnmower 100, the sensing end being disposed relative to the stopping area 201. The first control unit is electrically connected to the drive assembly 122, and the first control unit is wirelessly connected to the control module. In practical applications, the first control unit is used to control the drive assembly 122 to drive the brush body 121 to move, the second control unit is used to control the operation of the water pump 222, and the sensing module can be an infrared sensing module or a visual sensing module for identifying whether the lawnmower 100 is in the stopping area 201. When the lawnmower 100 is parked in the parking area 201, the sensing module sends a signal to the control module. The control module then controls the water pump 222 to start via the second control unit, causing the spray head 221 to spray cleaning fluid or water towards the sensing lens 111 of the lawnmower 100. The control module then sends a wireless signal to the first control unit, which in turn controls the drive assembly 122 to move the brush body 121 to clean the sensing lens 111. During this process, because the spray head 221 wets and properly rinses the surface of the sensing lens 111 before the brush body 121 cleans it, the brush body 121 does not cause significant wear to the surface of the sensing lens 111 due to dry brushing. This provides good protection for the sensing lens 111 and facilitates the mowing and cleaning maintenance of the lawnmower 100.

[0046] In some embodiments, the control module is also electrically connected to the first and second solenoid valves; thus, different liquid flows can be controlled by changing the connection between the spray head 221 and the cleaning fluid storage tank and the clean water tank. This helps improve the cleaning effect of the base station 200 on the sensor lens 111 of the lawnmower 100.

[0047] This application provides a lawnmower lens cleaning method using the aforementioned lawnmower lens cleaning system, which includes: S1. The lawnmower 100 is parked in the parking area 201 by a predetermined program or manually. In some embodiments, the lawnmower 100 may be an intelligent lawnmower that can automatically locate the base station 200 and park in the predetermined parking area 201 of the base station 200 when cleaning is needed or the battery is low, so that the base station 200 can clean and / or recharge it. In other embodiments, the lawnmower 100 may also be a manual lawnmower, which is parked in the predetermined parking area 201 of the base station 200 manually or remotely.

[0048] S2. The spray mechanism 22 is activated, causing the spray head 221 to spray water or cleaning fluid toward the sensor lens 111 to rinse and wet the sensor lens 111. S3, the drive assembly 122 drives the brush body 121 to reciprocate in contact with the sensing lens 111 to clean the sensing lens 111.

[0049] The above method allows the surface of the sensor lens to be pre-wetted or properly rinsed by the spray mechanism on the base station before the brush body washes it. This reduces the amount of dirt and other stains adhering to the sensor lens surface, thereby reducing the possibility of the sensor lens being scratched during brush washing.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
