[0003] To address the inconvenience of cleaning and maintaining lawnmowers in existing technologies, this invention provides a lawnmower cleaning base station.

[0004] This application provides a lawnmower cleaning base station comprising a base station base, a water storage tank, and a spraying assembly. The base station base has a cleaning water path and a wastewater discharge path. The water storage tank includes a clean water tank and a wastewater tank, both connected to the base station base. The clean water tank is connected to the cleaning water path, and the wastewater tank is connected to the wastewater discharge path. The spraying assembly is also connected to the base station base and communicates with the cleaning water path. The spraying assembly is connected to a first pump body, which is connected to the clean water tank.

[0005] The base station base is provided with a sewage collection chamber, which is connected to the sewage discharge path, and the sewage discharge path is connected to a second pump body.

[0006] The lawnmower cleaning base station also includes a filter element, which is disposed in the sludge collection chamber or the sewage discharge path. The filter element forms a first chamber and a second chamber arranged along the water flow direction. A filter body with filter holes is detachably disposed between the filter element and the first and second chambers.

[0007] In some embodiments, the base station base is further provided with a sewage outlet communicating with the sewage collection chamber, the sewage discharge path is connected to the sewage outlet, the first chamber is located on the side of the filter element close to the sewage outlet, and the second chamber is located on the side of the filter element away from the sewage outlet.

[0008] In some embodiments, the lawnmower cleaning base station further includes a power unit connected to the first pump body and the second pump body to drive the first pump body and the second pump body.

[0009] In some embodiments, the clean water tank and the wastewater tank are detachably connected to the base station base, and a communication structure is provided between the clean water tank and the base station base, and between the wastewater tank and the base station base; or The clean water tank and the wastewater tank are integrated with the base station base.

[0010] In some embodiments, the lawnmower cleaning base station further includes a disinfectant adding component connected to the clean water tank and having a chamber for holding disinfectant, the chamber being in communication with the clean water tank.

[0011] In some embodiments, the spray assembly includes a plurality of first spray heads, all of which are connected to the base station base. Each first spray head is provided with an angle adjustment structure to adjust the spray angle of the first spray head.

[0012] In some embodiments, the lawnmower cleaning base station further includes a control component, which includes a first sensor, a second sensor, and an MCU module.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] like Figure 1The illustrated lawnmower cleaning base station includes a base station base 100, a water storage tank 200, and a spray assembly 300. The base station base 100 has a cleaning water path and a wastewater discharge path. The water storage tank 200 includes a clean water tank 21 and a wastewater tank 22, both connected to the base station base 100. The clean water tank 21 is connected to the cleaning water path, and the wastewater tank 22 is connected to the wastewater discharge path. The spray assembly 300 is also connected to the base station base 100 and is connected to the cleaning water path. The spray assembly 300 is connected to a first pump body, which is connected to the clean water tank 21. Under the action of the first pump body, the spray assembly 300 can spray water towards the bottom of the lawnmower. It should be noted that the base station base 100 is used to park the lawnmower, the cleaning water path is used to transport clean water or a special cleaning solution, the wastewater discharge path is used to discharge the wastewater after cleaning from the lawnmower cleaning base station, the clean water tank 21 is used to store the clean water used for cleaning, and the wastewater tank 22 is used to store the wastewater generated after cleaning. Typically, the aforementioned cleaning water path and sewage discharge path can be pipes or channels installed on the lawnmower cleaning base station, and the spray assembly 300 can spray water towards various parts of the bottom of the lawnmower.

[0026] like Figure 2 , Figure 4 As shown, the base station base 100 is provided with a sewage collection chamber 101, which is connected to a sewage discharge path, and the sewage discharge path is connected to a second pump body 400. Sewage generated from cleaning the lawnmower can be collected in the sewage collection chamber 101 by natural flow, and the collected sewage is discharged through the second pump body 400.

[0027] like Figure 2 , Figure 4 As shown, the lawnmower cleaning base station provided in this application also includes a filter element 500. The filter element 500 is disposed in the sewage collection chamber 101 or the sewage discharge path. The filter element 500 forms a first chamber 1011 and a second chamber 1012 arranged along the water flow direction. A filter body 800 with filter holes is detachably disposed between the filter element 500 and the first chamber 1011 and the second chamber 1012. The filter element 500 is used to filter sewage to prevent excessively large solid matter in the sewage from clogging and damaging the second pump body 400. In practical applications, the filter body 800 can be a disposable net, and the filter element 500 can be a filter screen structure with a mesh size of 2 mm. After sewage enters the sewage collection chamber 101, it flows from the first chamber 1011 into the second chamber 1012. The net and the filter element 500 will block solid matter mixed in the sewage that is larger than its mesh diameter in the first chamber 1011 to prevent clogging and damage to the second pump body 400. After cleaning, users can directly remove the mesh bag and discard it along with the filtered grass clippings and other debris. A new mesh bag can be replaced for the next use, making cleaning quick and easy. Alternatively, users can remove the mesh bag, wash it, and reuse it.

[0028] Specifically, the filter body 800 is a mesh bag, detachably mounted on the filter element 500. The filter element 500 includes a filter section 51 for filtration and a pressing ring 52 for fixing the edge of the mesh bag. The pressing ring 52 is detachably connected to the filter section 51. The filter section 51 has a filter cavity, and the sidewall of the filter cavity has holes. When the mesh bag is mounted on the filter element 500, the edge of the mesh bag is pressed between the edge of the filter section 51 and the pressing ring 52 to fix the mesh bag. In some embodiments, the pressing ring 52 and the filter section 51 can be connected by magnetic attraction.

[0029] With the above design, after the lawnmower finishes its mowing operation, it can be driven into the lawnmower cleaning station and parked on the station base 100. The spray assembly 300 draws water from the clean water tank 21 through the first pump and sprays water towards the bottom of the lawnmower to wash away the attached dirt, causing it to fall off and flow into the wastewater collection chamber 101 for collection. The collected wastewater is then filtered by the filter element 500 and discharged into the wastewater tank 22 by the second pump 400 for collection. The above cleaning process only requires driving the lawnmower into the lawnmower cleaning station and parking it on the station base 100. The spray assembly 300 can draw water from the clean water tank 21 and directly rinse the bottom of the lawnmower, without the need for an external water source or manual operation such as turning the lawnmower over, greatly reducing the difficulty of cleaning and maintaining the lawnmower. The wastewater generated during the cleaning process is temporarily stored in the wastewater tank 22, so there is no need to worry about wastewater discharge. The above design is highly integrated, which greatly facilitates the cleaning and maintenance of the lawnmower.

[0030] The technical details of each component will be introduced below.

[0031] In some implementations, such as Figure 4 , Figure 5 As shown, the base station base 100 is also provided with a sewage outlet 102 connected to the sewage collection chamber 101. A sewage discharge path is connected to the sewage outlet 102. The second chamber 1012 is located on the side of the filter element 500 near the sewage outlet 102, and the first chamber 1011 is located on the side of the filter element 500 away from the sewage outlet 102. The second pump body 400 is connected to the second chamber 1012. This design ensures that when sewage enters the sewage discharge path, it will not be mixed with excessively large solid materials, guaranteeing the normal flow of the sewage discharge path and the normal operation of the second pump body 400. The first chamber 1011 has a certain storage capacity for excessively large solid materials, reducing the frequency of manual maintenance.

[0032] Further, please refer to Figure 4 , Figure 5In some embodiments, the volume of the first chamber 1011 is more than twice the volume of the second chamber 1012. Specifically, in practical applications, the volume of the first chamber 1011 is 10 liters, and the volume of the second chamber 1012 is 4 liters. Since wastewater is collected in the first chamber 1011 immediately, its larger volume reduces the possibility of overflow. The larger volume also allows for the temporary storage of larger solids, facilitating continuous operation of the lawnmower cleaning station. Wastewater entering the second chamber 1012, having been filtered by the filter element 500, does not contain larger solids and can be quickly pumped away by the second pump body 400, preventing accumulation.

[0033] Furthermore, such as Figure 4 , Figure 5 As shown, in some embodiments, the first chamber 1011 is formed above the second chamber 1012 relative to the bottom surface of the base station base 100. This design facilitates the rapid discharge of wastewater, which will be analyzed in detail below: Please see Figure 4 , Figure 5 To understand this, wastewater first enters the first chamber 1011, then flows through the filter element 500, and finally enters the second chamber 1012. If there are too many large-diameter solids in the first chamber 1011, the filtration efficiency of the filter element 500 will decrease. When the filtration efficiency of the filter element 500 decreases to a certain level, the wastewater in the first chamber 1011 will accumulate. With the above design, since the first chamber 1011 is located above the second chamber 1012, when the sewage in the first chamber 1011 becomes rich, it will completely submerge the connection between the first chamber 1011 and the second chamber 1012, i.e., the location of the filter element 500. At this time, after the second pump body 400 pumps out the sewage from the second chamber 1012, it will create a negative pressure environment in the second chamber 1012, which will then generate a negative pressure suction effect on the sewage rich in the first chamber 1011, so as to help the sewage filter from the first chamber 1011 to the second chamber 1012, increase the filtration efficiency of the filter element 500, and increase the difficulty of sewage overflowing the collection chamber 101.

[0034] In some other embodiments, the base station base 100 is further provided with an agitation device (not shown in the figure). This agitation device has an agitation end, which is located near the filter element 500 to agitate the solid matter filtered out by the filter element 500, thereby improving the filtration efficiency of the filter element 500. Specifically, the agitation device includes an agitation motor and an agitation paddle connected to the output end of the agitation motor. The agitation motor is located on the base station base 100 and is connected to a power supply or energy storage device such as a battery. The agitation paddle is located on the side of the filter element 500 near the first chamber 1011. The agitation paddle agitates the wastewater by rotating, thereby causing the solid matter accumulated on the side of the filter element 500 near the first chamber 1011 to be continuously moved by the disturbance of the wastewater, preventing long-term clogging of the filter holes and increasing the filtration efficiency of the filter element 500.

[0035] In some embodiments, the lawnmower cleaning base station provided in this application further includes an energy component (not shown in the figures), which is connected to the first pump body and the second pump body 400 to drive the first pump body and the second pump body 400. In practical applications, the energy component can be a rechargeable battery, which can supply power to the first pump body and the second pump body 400 when there is no external power source. This allows the lawnmower cleaning base station provided in this application to perform cleaning operations on lawnmowers in usage scenarios where it is inconvenient to connect to a power source, such as outdoor grasslands or mobile cleaning operations. In particular, through the above design, the lawnmower cleaning base station can be installed on a mobile vehicle so that the lawnmower can be cleaned and maintained at any time.

[0036] Furthermore, in some embodiments, the lawnmower cleaning base station provided in this application also includes a power generation device (not shown in the figure), which is connected to the aforementioned energy component to supplement the energy component with electrical energy. In practical applications, the aforementioned power generation device can be a solar power generation device or a fuel power generation device, such as a gasoline or diesel generator, which can charge the energy component when its energy is insufficient, thereby extending the operating time of the lawnmower cleaning base station.

[0037] Preferably, the aforementioned power generation device is a solar power generation device. It should be noted that: First, people typically use lawnmowers to trim lawns in good weather. In good weather, solar power generation devices can generate sufficient power, making them more suitable for the working environment of lawnmowers. Second, the lawnmower cleaning station is used to clean the lawnmower after it has finished mowing. In typical usage scenarios, such as home use, lawnmowers are used periodically, not daily or frequently. Therefore, considering practical usage, the lawnmower cleaning station can have a sufficiently long standby time to allow the solar power generation device to replenish the energy source. Furthermore, solar power generation devices produce clean energy, eliminating the need for additional consumables such as fuel and avoiding the exhaust fumes produced by burning polluting fuels. They also do not produce odors or noise during power generation. In conclusion, solar power generation devices are better suited for typical usage scenarios, such as home use.

[0038] In some implementations, such as Figure 1 , Figure 2 As shown, the clean water tank 21 and the wastewater tank 22 are detachably connected to the base station base 100. A communication structure connecting the clean water tank 21 to the base station base 100 and communicating with the clean water path is provided, and a communication structure connecting the wastewater tank 22 to the base station base 100 and communicating with the wastewater path is also provided (not shown in the figure). Normally, the above-mentioned communication structures are located at the bottom of the clean water tank 21 and the wastewater tank 22, and can be a common self-locking connector. When the clean water tank 21 or the wastewater tank 22 is connected to the base station base 100, the above-mentioned communication structure opens to allow the clean water tank 21 or the wastewater tank 22 to communicate with the clean water path or the wastewater path; when the clean water tank 21 or the wastewater tank 22 is separated from the base station base 100, the above-mentioned communication structure closes to seal the bottom of the clean water tank 21 or the wastewater tank 22 to prevent leakage of clean water or wastewater.

[0039] In practical applications, the above design allows the lawnmower cleaning base station to be used in scenarios where water access or drainage is inconvenient.

[0040] In some other embodiments, the aforementioned clean water tank 21 and wastewater tank 22 are integrated with the base station base 100. This design enhances the compactness of the lawnmower cleaning base station.

[0041] In some implementations, such as Figure 1 , Figure 2As shown, the lawnmower cleaning base station provided in this application also includes a disinfectant adding component 600. The disinfectant adding component 600 is connected to the clean water tank 21 and has a chamber 02 for holding disinfectant, which is connected to the clean water tank 21. The disinfectant adding device can dissolve disinfectant in the water in the clean water tank 21. Firstly, the disinfectant can make the water sprayed by the spray component 300 have a bactericidal and disinfecting effect, which can inhibit the growth of bacteria on the lawnmower chassis. Secondly, the water in the clean water tank 21 contains disinfectant, which can prevent the growth of moths and algae in the clean water during storage. Moths and algae will pollute the clean water and may also block the communication structure between the clean water tank 21 and the cleaning water channel. Thirdly, since the clean water contains disinfectant, the wastewater generated after cleaning the lawnmower will also contain disinfectant. The wastewater contains a large amount of organic matter, and the disinfectant can inhibit the growth and reproduction of bacteria in the wastewater, thereby preventing the wastewater in the wastewater tank 22 from producing an odor under the action of bacteria.

[0042] Specifically, the disinfectant mentioned above can be a solution containing chlorine dioxide, which is easily soluble in water and inexpensive.

[0043] It should be added that the disinfectant adding component 600 also has a pumping mechanism for pumping disinfectant into the clean water tank 21. In some embodiments, the pumping mechanism can be a press-type pumping mechanism, in use, the disinfectant is pumped from the chamber 02 into the clean water tank 21 by squeezing, which is similar to the pumping mechanism of common shower gels and shampoos. In other embodiments, the disinfectant adding component 600 includes a pump body for pumping out disinfectant and a control component. The pump body is connected to the chamber 02 and the clean water tank 21, and the control component is electrically connected to the pump body to control the pump body to pump out disinfectant. In practical applications, the above design can directly pump disinfectant into the clean water tank 21 without manual addition, making it more convenient to use. Furthermore, the control component also includes a metering module for controlling the pumped-out dosage of disinfectant, and the metering module is connected to the pump body. In this way, the predetermined single pumping dosage can be set according to the volume of the clean water tank 21 and the user's needs, ensuring the disinfection effect while avoiding the waste of disinfectant.

[0044] In some implementations, such as Figure 1 , Figure 2As shown, the spray assembly 300 includes multiple first spray heads 31, all of which are connected to the base station base 100. Each first spray head 31 is equipped with an angle adjustment structure to adjust its spray angle. These multiple first spray heads 31 are used to clean different parts of the lawnmower's bottom. The angle adjustment structure allows for adjustment of the spray angle of the spray assembly 300, thus adapting to different lawnmower bottom structures and enhancing the adaptability and cleaning effect of the lawnmower cleaning base station.

[0045] Specifically, such as Figure 3 , Figure 6 , Figure 7 , Figure 8 As shown, the first spray head 31 includes a nozzle body 311, a connecting seat 312, a guide ball head 313, and a locking member 314. The connecting seat 312 is disposed on the nozzle body 311 and has a spray nozzle 01. The guide ball head 313 is movably connected to the connecting seat 312 and is disposed at the spray nozzle 01. The locking member 314 is connected to the connecting seat 312 and abuts against the guide ball head 313 to press and lock the guide ball head 313. The locking member 314, the guide ball head 313, and the connecting seat 312 cooperate to form the angle adjustment structure described above. The locking member 314 includes a locked state and a relaxed state. The guide ball head 313 is provided with a guide channel 03 communicating with the spray nozzle 01. One end of the guide channel 03 is connected to the spray nozzle 01, and the other end is used to face the bottom of the lawnmower. When the locking member 314 is in the relaxed state, the guide ball head 313 can roll relative to the connecting seat 312 within a certain range to change the orientation of the guide channel 03. When the locking member 314 is in the locked state, it presses the guide ball head 313 to prevent it from rolling, thereby locking the guide ball head 313 and causing the guide channel 03 to face a predetermined direction. In some embodiments, the locking member 314 is sleeved on the outside of the connecting seat 312 and threadedly connected to the connecting seat 312. The locking member 314 gradually approaches the guide ball head 313 through thread engagement to achieve pressing and locking of the guide ball head 313.

[0046] In some embodiments, the lawnmower cleaning base station provided in this application further includes a control component. The control component includes a first sensor, a second sensor, and an MCU module. The first sensor is disposed on the base station base 100 and positioned relative to the lawnmower chassis. The second sensor is disposed on the base station base 100 and senses the position of the lawnmower relative to the base station base 100. The MCU module is electrically connected to the first sensor, the second sensor, the first pump body, and the second pump body 400. Specifically, the first sensor can be a vision sensor camera, which can photograph and identify the bottom of the lawnmower. Using an internal visual training database for determining whether the bottom of the lawnmower is clean, the camera compares the photographed image of the lawnmower chassis with the visual training database to determine whether the bottom of the lawnmower is clean. The second sensor can be an infrared distance sensor, which determines whether the lawnmower has entered the predetermined position of the lawnmower cleaning base station by emitting and receiving infrared light. Through this design, the lawnmower cleaning system can automatically determine whether the lawnmower has entered the lawnmower cleaning base station and whether the lawnmower has been cleaned. If the lawnmower enters the lawnmower cleaning station, the MCU module controls the first and second pumps 400 to start pumping water to clean the lawnmower and discharge the wastewater generated during the cleaning process. If the lawnmower is clean, the cleaning process stops; if the lawnmower is not clean, the cleaning operation continues.

[0047] In some embodiments, the lawnmower cleaning base station provided in this application includes a cleaning mode switching module, and a first pump body is a variable frequency pump, electrically connected to the cleaning mode switching module. The cleaning mode switching module changes the cleaning intensity on the bottom of the lawnmower by controlling the operating frequency of the first pump body, in order to adapt to different cleaning needs and different stages in the cleaning process.

[0048] Furthermore, the aforementioned first spray head 31 includes a jet nozzle and an atomizing nozzle, both of which are connected to the first pump body. Solenoid valves for controlling water flow are installed between the jet nozzle and the first pump body, and between the atomizing nozzle and the first pump body. These solenoid valves are electrically connected to the cleaning mode switching module. Through this design, the cleaning mode switching module can change the cleaning mode of the lawnmower cleaning base station by controlling the connection between the jet nozzle and the atomizing nozzle and the first pump body. The atomizing nozzle can thoroughly and comprehensively rinse and wet the bottom of the lawnmower, while the jet nozzle can spray a high-pressure jet of water for a high-intensity rinse of the bottom of the lawnmower.

[0049] In some implementations, such as Figure 9 , Figure 10As shown, the lawnmower cleaning base station provided in this application also includes a cover 700, which covers the base station base 100 and is detachably connected to the base station base 100 via a quick-release structure. The cover 700 and the base station base 100 together form a cleaning cavity S. The cover 700 can prevent water splashing during the cleaning process. When it is necessary to clean the lawnmower cleaning base station, the cover 700 can be removed to facilitate cleaning of the lawnmower cleaning base station.

[0050] Specifically, the quick-release structure described above can be a snap-fit ​​mechanism that allows for rapid connection and separation. Alternatively, in some other embodiments, the cover 700 is provided with a first magnetic element, and the base station base 100 is provided with a second magnetic element. When the cover 700 is assembled onto the base station base 100, the first magnetic element and the second magnetic element are positioned opposite each other and magnetically attracted to each other, thereby forming the quick-release structure between the cover 700 and the base station base 100.

[0051] In some implementations, such as Figure 10 As shown, the aforementioned cover 700 includes a main body 71, a second water spray head 72, and a water supply connector. The second water spray head 72 is disposed inside the main body 71, and the water supply connector is connected to the main body 71 and communicates with the second water spray head 72. A rinsing water passage is connected between the water supply connector and the second water spray head 72. The rinsing water passage can be a pipe or channel installed on the cover 700. The second water spray head 72 is used to spray water toward the base station base 100 to rinse the base station base 100 and the outer surface of the lawnmower to a certain extent. Correspondingly, the base station base 100 is provided with a water supply section that communicates with the water supply assembly. When the cover 700 is placed over the base station base 100, the water supply connector communicates with the water supply section. The water supply section is used to connect to the water supply connector to supply water to each rinsing head. In this way, the water supply assembly supplies water to both the spray assembly 300 and the rinsing heads on the cover 700, enhancing the integration of the lawnmower cleaning base station.

[0052] Specifically, the water supply unit is equipped with a socket. When the cover 700 is installed on the base station base 100, the water supply connector is inserted into the socket so that the water supply component can be connected to the flushing head.

[0053] In some embodiments, the lawnmower cleaning base station also includes a drying assembly disposed on the base station base 100 and having a drying air outlet facing the lawnmower chassis. Specifically, the drying assembly is internally equipped with an airflow generating device (fan or turbine) and an electric heating device (heating wire). The generated airflow is heated by the heating wire and then blown out from the drying air outlet, thereby drying the bottom of the lawnmower, preventing residual water from breeding bacteria and producing odors, and also preventing the lawnmower components from rusting.
