Description

Technical Field

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

[0002] With the development of smart device technology, smart lawnmowers are gradually becoming widely used. Lawnmowers can replace manual labor in trimming and cutting lawns within a designated area. They can autonomously control their travel route and work area. After mowing, a large amount of grass clippings accumulate on the mower's chassis. If not cleaned promptly, these clippings will adhere to the chassis with the grass juice, making them very difficult to remove. Therefore, it is essential to clean the lawnmower's chassis after each use. Typically, a lawnmower cleaning station is installed to facilitate parking and cleaning. The lawnmower can automatically enter and leave this station. When the mower finishes mowing and docks at the cleaning station, the station usually uses water jets to wash the chassis, removing the remaining grass clippings. The water pressure of the water jet from the lawnmower cleaning station has a significant impact on the cleaning effect on the lawnmower chassis. However, lawnmower cleaning stations usually have multiple water nozzles. The multiple nozzles can easily lead to insufficient water pressure when cleaning the lawnmower, thus affecting the rinsing effect on the lawnmower chassis. Summary of the Invention

[0003] To address the problem of insufficient water pressure in the water jet from existing lawnmower cleaning base stations, which reduces the cleaning effect on the lawnmower chassis, this invention provides a lawnmower cleaning base station.

[0004] This application provides a lawnmower cleaning base station comprising a base station base, a water spraying component, a water distribution device, and at least two first pump bodies. The base station base is provided with a sludge collection chamber. The water spraying component is connected to the base station base and has multiple spray heads. The water distribution device has at least one inlet end and multiple outlet ends, with each outlet end connected to one of the spray heads. At least two of the first pump bodies are connected to the inlet end via a first pipe.

[0005] The lawnmower cleaning base station provided in this application also includes a second pump body, which is connected to the sludge collection chamber via a second pipe.

[0008] In some embodiments, the base station base is further provided with a sewage discharge connector that communicates with the sewage discharge outlet. A sewage flow channel is formed between the sewage discharge outlet and the end of the sewage discharge connector away from the sewage discharge outlet. The cross-sectional area of ​​the sewage flow channel is S3, where S3≥2S1.

[0009] In some embodiments, the second pipe is connected to the sewage discharge connector, and one end of the second pipe used to connect to the sewage discharge connector is sleeved on the outside of the sewage discharge connector.

[0010] In some embodiments, the second pump body has a second pump inlet and a second pump outlet, the second conduit is connected to the second pump inlet, and one end of the second conduit used to connect to the second pump inlet is at least partially inserted into the port of the second pump inlet.

[0011] In some embodiments, the lawnmower cleaning base station further includes a control component, and the plurality of first pump bodies are electrically connected to the control component; The first pump body is a fixed-frequency pump, and the control component controls the number of the first pump bodies in operation.

[0012] In some embodiments, the water inlet is provided with a multi-channel adapter with multiple connection ports, and multiple first pump bodies are connected to each connection port of the multi-channel adapter through the first pipe; Along the first pipeline, a one-way valve is provided between each of the first pump bodies and the water distribution device.

[0013] In some embodiments, the lawnmower cleaning base station further includes a water tank, which is connected to the first pump body; The water distribution device is provided with multiple water inlets, which are evenly distributed along the side of the water distribution device.

[0014] In some embodiments, the water distribution device is provided with a water distribution chamber and a plurality of water distribution channels communicating with the water distribution chamber. The plurality of water distribution channels are correspondingly connected to a plurality of water outlets, and each water distribution channel is connected to the water distribution chamber.

[0015] Compared with existing technologies, the lawnmower cleaning base station provided by this invention has the following advantages: The lawnmower cleaning base station provided by this application can distribute the cleaning water pumped in by the first pump body through a water distribution device, so that the cleaning water can be evenly sprayed from each spray head to rinse various parts of the lawnmower chassis.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] like Figure 1The illustrated lawnmower cleaning base station includes a base station base 100, a water spraying component 200, a water distribution device 300, and at least two first pump bodies 400. The base station base 100 has a collection chamber 101 for collecting wastewater and debris. The water spraying component 200 is connected to the base station base 100 and has multiple spray heads 21 facing the lawnmower chassis. The water distribution device 300 has at least one inlet end 31 and multiple outlet ends 32, each connected to a spray head 21. Both first pump bodies 400 are connected to the inlet end 31 via a first pipe 600. The first pump 400 pumps the cleaning water into the water distribution device 300. The cleaning water enters the water distribution device 300 from the inlet 31 and is then distributed to various outlets 32. Each outlet 32 ​​is connected to a spray head 21, allowing all spray heads 21 to spray water simultaneously for a wide-area rinsing of the lawnmower's chassis. The wastewater and grass clippings washed off the lawnmower chassis are collected in the collection chamber 101 of the base station base 100 along with the wastewater flow for subsequent processing.

[0025] The design of at least two first pump bodies 400 increases the water intake of the water distribution device 300 per unit time, and correspondingly increases the water output of the water outlet 32 ​​of the water distribution device 300 per unit time. In other words, the design of at least two first pump bodies 400 enhances the water pressure of the water jet from the spray head 21, resulting in a better rinsing and cleaning effect on the chassis of the lawnmower.

[0026] It should be noted that, because the water distribution device 300 has multiple outlets 32, while the number of inlet ends 31 is far less than the number of outlets 32, the water entering from the inlet ends 31 is distributed to each outlet end 32, causing a drop in water pressure at each outlet end 32, making it difficult to guarantee a good rinsing effect on the lawnmower chassis. Therefore, the design of at least two first pump bodies 400, by increasing the water intake, ensures that the water jet from the spray head 21 has good water pressure, which can produce a good rinsing and cleaning effect on the lawnmower chassis.

[0027] Please continue reading. Figure 1 The lawnmower cleaning station provided in this application also includes a second pump body 500, which is connected to the sewage collection chamber 101 via a second pipe 700. The second pump body 500 is used to pump the sewage collected in the sewage collection chamber 101 out of the sewage collection chamber 101, and then discharge the collected sewage into a container for collecting sewage or directly into the sewer system.

[0028] In summary, the lawnmower cleaning base station provided in this application can distribute the cleaning water pumped in by the first pump body 400 through the water distribution device 300, so that the cleaning water can be evenly sprayed from each water nozzle 21 to wash various parts of the lawnmower chassis. Furthermore, by setting multiple first pump bodies 400, it ensures that the water nozzles 21 can spray water with sufficient pressure to clean the lawnmower chassis. This guarantees the cleaning effect of the lawnmower cleaning base station on the lawnmower.

[0029] The technical details of each component will be introduced below.

[0030] In some implementations, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 To understand this, the cross-sectional area of ​​the cavity of the first pipe 600 is S1, and the cross-sectional area of ​​the cavity of the second pipe 700 is S2, where S2 ≥ 2S1. Specifically, the cross-sectional area of ​​the cavity of the first pipe 600 is 1 square centimeter, and the cross-sectional area of ​​the cavity of the second pipe 700 is 3 square centimeters. This design improves the efficiency of sewage discharge from the collection chamber 101. In practical applications, sewage in the collection chamber 101 needs to be discharged promptly to prevent it from accumulating and overflowing. This design provides a good structural guarantee for the timely discharge of sewage from the collection chamber 101, and a larger cavity diameter allows for a larger flow rate.

[0031] In practical applications, because the spray head 21 needs to ensure effective rinsing of the lawnmower chassis, the water flow velocity in the first pipe 600 is usually greater than that in the second pipe 700. Therefore, to ensure that the second pipe 700 can quickly discharge wastewater, the cross-sectional area of ​​the second pipe 700's cavity needs to be larger than that of the first pipe 600's cavity. Based on the above description, the design of S2≥2S1 can structurally prevent the wastewater in the collection chamber 101 from failing to be discharged in a timely manner.

[0032] To better prevent the sewage in the collection chamber 101 from failing to drain in a timely manner, the pumping volume of the second pump body 500 per unit time is greater than the sum of the pumping volumes of each of the first pump bodies 400 per unit time. Specifically, as shown... Figure 1 , Figure 3 , Figure 4 , Figure 5As shown, the lawnmower provided in this application includes two first pump bodies 400 and one second pump body 500. The pumping rate of the first pump body 400 is 8 L / min, therefore the pumping rate of the second pump body 500 must be greater than 16 L / min, specifically 20 L / min. This ensures that the drainage rate of the wastewater collection chamber 101 is always greater than the sum of the spray rates of all the spray heads 21, guaranteeing timely discharge of wastewater.

[0033] In some embodiments, the second pump body 500 can be a centrifugal impurity pump, so that even if the sewage contains a large amount of solid matter such as grass clippings and silt, the second pump body 500 can still pump the solid matter such as grass clippings and silt out of the sewage chamber along with the sewage.

[0034] In some implementations, such as Figure 1 , Figure 6 , Figure 7 As shown, the base station base 100 includes a filter element 11, which is disposed in the sludge collection chamber 101 to form a first chamber 1011 and a second chamber 1012 in the sludge collection chamber 101. The filter element 11 has filter holes. The filter element 11 can filter sewage, filtering out solid materials such as grass clippings and mud with a volume larger than the diameter of the filter holes, preventing them from entering the second pipe 700 and causing blockage, and from entering the second pump body 500 and causing damage to the second pump body 500.

[0035] Please continue reading. Figure 6 , Figure 7 The base station base 100 is also provided with a sewage outlet 102 communicating with the sewage collection chamber 101. The first chamber 1011 is located on the side of the filter element 11 near the sewage outlet 102, and the second chamber 1012 is located on the side of the filter element 11 away from the sewage outlet 102. Through the above design, the filter element 11 can block all large solid materials in the second chamber 1012, thereby preventing them from entering the second pipe 700 and the second pump body 500 and causing pipe blockage and pump damage.

[0036] In some implementations, such as Figure 7 As shown, the second chamber 1012 is formed above the first chamber 1011, relative to the bottom surface of the base station base 100. This design facilitates the rapid discharge of wastewater, as detailed below: Please see Figure 7It is understandable that the sewage first enters the second chamber 1012, then flows through the filter element 11, then enters the first chamber 1011, and finally exits from the second pipe 700. If there are too many large-diameter solids in the sewage, the filtration efficiency of the filter element 11 will decrease. When the filtration efficiency of the filter element 11 decreases to a certain extent, the sewage in the second chamber 1012 will accumulate more and more. With the above design, since the second chamber 1012 is located above the first chamber 1011, when the sewage in the second chamber 1012 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 11). At this time, after the second pump body 500 pumps out the sewage from the first chamber 1011, it will create a negative pressure environment in the first chamber 1011, which will then generate a negative pressure suction effect on the sewage rich in the second chamber 1012, so as to help the sewage filter from the second chamber 1012 to the first chamber 1011, increase the filtration efficiency of the filter element 11, and prevent the sewage from overflowing the collection chamber 101.

[0037] In some other embodiments, the base station base 100 is further provided with an agitation device. This agitation device has an agitation end positioned close to the filter element 11 to agitate the solid matter filtered out by the filter element 11, thereby improving the filtration efficiency of the filter element 11. 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 source or energy source (such as a battery or energy storage device). The agitation paddle is positioned on the side of the filter element 11 near the second chamber 1012. The agitation paddle agitates the wastewater by rotating, causing the solid matter accumulated on the side of the filter element 11 near the second chamber 1012 to move continuously due to the disturbance of the wastewater, thus preventing prolonged clogging of the filter holes and increasing the filtration efficiency of the filter element 11.

[0038] In some implementations, such as Figure 1 , Figure 6 , Figure 7As shown, the base station base 100 is also provided with a sewage discharge connector 12 connected to the sewage discharge outlet 102. A sewage flow channel 103 is formed between the sewage discharge outlet 102 and the end of the sewage discharge connector 12 away from the sewage discharge outlet 102. The cross-sectional area of ​​the sewage flow channel 103 is S3, where S3 ≥ 2S1. The sewage discharge connector 12 is used to connect to the second pipe 700. After the sewage in the collection chamber 101 flows out of the sewage discharge outlet 102, it enters the sewage flow channel 103 inside the sewage discharge connector 12, and then enters the second pipe 700. Through the above design, similar to the size relationship between the cavities of the first pipe 600 and the second pipe 700, the above design can structurally ensure that the sewage discharge rate is greater than the sum of the spray rates of all the water spray heads 21, which is beneficial to ensure that the sewage can be quickly discharged from the collection chamber 101. Specifically, the cross-sectional area of ​​the cavity of the first pipe 600 is 1 square centimeter, and the cross-sectional area of ​​the sewage flow channel 103 is 3 square centimeters.

[0039] In some implementations, such as Figure 1 , Figure 6 , Figure 7 As shown, the second pipe 700 is connected to the sewage discharge connector 12, and one end of the second pipe 700 for connecting to the sewage discharge connector 12 is sleeved on the outside of the sewage discharge connector 12. This design ensures that solid matter discharged from the sewage discharge connector 12 can smoothly enter the cavity of the second pipe 700 without being blocked by the end of the second pipe cavity. For easier understanding, please refer to the following... Figure 8 , Figure 9 , Figure 10 , Figure 11 Detailed explanation: If the end of the second pipe 700 is inserted into the interface of the first connector (see...) Figure 9 Because the second pipe 700 has a certain thickness, solid matter flowing out of the sewage discharge connector 12 may collide with the end of the second pipe 700, thus affecting the discharge of solid matter. However, through the above design (see...) Figure 8 This can avoid the aforementioned adverse situations.

[0040] In some implementations, such as Figure 1 As shown, the second pump body 500 has a second pump inlet end 51 and a second pump outlet end. A second pipe 700 is connected to the second pump inlet end 51, and at least one end of the second pipe 700 used to connect to the second pump inlet end 51 is inserted into the port of the second pump inlet end 51. This design ensures that solid material flowing out of the second pipe 700 can smoothly enter the second pump body 500 without being blocked by the second pump inlet end 51 of the second pump body 500. For easier understanding, please refer to the following... Figure 8 , Figure 9 , Figure 10 , Figure 11 Detailed explanation: If the end of the second pipe 700 is sleeved outside the second pump inlet 51 (see...) Figure 11 If the second pump inlet 51 is located inside the cavity of the second pipe 700, the solid material flowing into the second pump body 500 from the second pipe 700 may collide with the end of the second pump inlet 51, affecting the discharge of the solid material. However, through the above design (see...), Figure 10 This can avoid the aforementioned adverse situations.

[0041] In some embodiments, the lawnmower cleaning base station provided in this application further includes a control component, with multiple first pump bodies 400 electrically connected to the control component. The control component can be an MCU module. The multiple first pump bodies 400 are fixed-frequency pumps, and the control component controls the number of first pump bodies 400 operating. Fixed-frequency pumps are cheaper than variable-frequency pumps. By changing the number of fixed-frequency pumps operating, the water inlet 31 of the water distribution device 300 is changed per unit time, thereby changing the water pressure of the spray head 21 and adapting to different cleaning intensities. This design can reduce production costs.

[0042] In some embodiments, the aforementioned water inlet 31 is provided with a multi-channel adapter 800 having multiple connection ports, and multiple first pump bodies 400 are connected to each connection port of the multi-channel adapter 800 via first pipes 600. For example... Figure 3 , Figure 4 , Figure 5 As shown, the multi-channel adapter 800 has a "Y" shaped structure, with one end connected to the water inlet 31 and the other end used to connect to the two first pump bodies 400. The "Y" shaped structure can reduce the mutual interference effect of water flow in the two channels when they converge, which is beneficial to reducing the energy loss of water flow pumped out by the two first pump bodies 400 when they converge, and improving the pressurization effect of the two first pump bodies 400.

[0043] Furthermore, along the first conduit 600, a one-way valve is provided between each first pump body 400 and the water distribution device 300, with the flow direction of the one-way valve from the first pump body 400 towards the water distribution device 300. In practical applications, the control component can control the number of first pump bodies 400 operating, thereby changing the impact intensity of the water flow when cleaning the lawnmower. Please refer to [link / reference]. Figure 5 To understand this, when a portion of the first pump body 400 is not operating, the water flow in the first pipe 600 will exert pressure on the non-operating first pump body 400, causing it to reverse and resulting in pressure loss. Through the above design, the check valve can effectively prevent the water flow in the second pipe 700 from exerting pressure on the non-operating first pump body 400, thus avoiding pressure loss.

[0044] In some implementations, such as Figure 1 , Figure 6 As shown, the lawnmower cleaning base station provided in this application also includes a water tank 900, which is connected to the first pump body 400. The water tank 900 is used to store cleaning water, so that the chassis of the lawnmower can still be effectively washed even when the external water supply is insufficient or interrupted.

[0045] In some embodiments, the water tank 900 may include a clean water tank 900 and a wastewater tank 900. The clean water tank 900 stores clean water used for cleaning, and the wastewater tank 900 stores wastewater after cleaning. The wastewater tank 900 is connected to the second pump body 500. In practical applications, the second pump body 500 pumps wastewater from the collection chamber 101 into the wastewater tank 900 for storage. This design facilitates the use of the lawnmower cleaning base station in scenarios where drainage is inconvenient.

[0046] The aforementioned water distribution device 300 is provided with multiple water inlet ends 31, which are evenly distributed along the side of the water distribution device 300. This design helps to evenly distribute the water pressure at each water outlet end 32 of the water distribution device 300, so that each spray head 21 can have good spray water pressure.

[0047] like Figure 3 , Figure 4 , Figure 5 As shown, to further even out the water pressure at each outlet 32 ​​of the water distribution device 300, multiple outlets 32 are evenly distributed along the side of the water distribution device 300. In addition to the aforementioned benefits, this design also facilitates the connection of pipes between each outlet 32 ​​and the spray head 21. The details are as follows: In practical applications, each water nozzle 21 is positioned at a different location on the base station base 100 to enhance the overall rinsing effect on the lawnmower chassis. Multiple water outlets 32 are evenly distributed along the side of the water distribution device 300, allowing the side of the water distribution device 300 to have outlets 32 facing different directions. This enables each water nozzle 21 to be connected to an outlet with the appropriate orientation, reducing the bends and length of the pipeline and facilitating the connection between the water distribution device 300 and each water nozzle 21.

[0048] In some implementations, such as Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, the water distribution device 300 has a water distribution chamber 301 and multiple water distribution channels 302 connected to the water distribution chamber 301. These multiple water distribution channels 302 are connected to multiple water outlets 32, and each water distribution channel 302 is connected to the water distribution chamber 301. Water flows in from the inlet 31 and then into the water distribution chamber 301. The water distribution chamber 301 acts as a buffer for the water flow. When the water distribution chamber 301 is full, the water inside the chamber exerts a relatively uniform pressure on its inner wall. The water first flows into the water distribution chamber 301 and then into each water distribution channel 302 connected to it, which helps to make the water pressure at each water outlet 32 ​​more uniform, thus allowing each spray head 21 to effectively wash the chassis of the lawnmower.

[0049] In some implementations, such as Figure 4 , Figure 5 As shown, the water distribution device 300 has one inlet end 31 and multiple outlet ends 32. The water distribution chamber 301 is symmetrical about the W plane. An inlet channel 303 is provided inside the water distribution device 300, connecting the inlet end 31 and the water distribution chamber 301. The inlet channel 303 and the inlet end 31 are located on or near the W plane. The water distribution device 300 also has two symmetrically arranged water distribution channels, A302 and B302, about the W plane. Water distribution channel A302 connects to outlet end A32, and water distribution channel B302 connects to outlet end B32. Through this design, the water pressure in water distribution channel A302 and water distribution channel B302 can be the same or similar, thus ensuring that the outlet water pressure in outlet end A32 and outlet end B32 is also the same or similar. Corresponding to the above design, each spray head 21 includes an A spray head A21 and a B spray head B21 located on opposite sides (e.g., left and right sides) of the base station base 100. An A water distribution channel A302 is connected to the A spray head A21, and a B water distribution channel B302 is connected to the B spray head B21. This design allows the A spray head A21 and the B spray head B21 to have the same or similar spray pressure, thus enabling the lawnmower cleaning base station to clean opposite sides of the lawnmower to the same or similar degree in practical applications. This improves the cleaning effect of the lawnmower cleaning base station.

[0050] Furthermore, such as Figure 4 , Figure 5 As shown, the relative directions of the above-mentioned spray head A21 and spray head B21 are consistent with the relative directions of the above-mentioned water inlet end 31 A and water inlet end 31 B. This design allows for convenient installation of pipelines between the spray head 21 and the water outlet end 32.

[0051] In some other embodiments, the water distribution device 300 has multiple inlet ends 31 and multiple outlet ends 32. The water distribution chamber 301 is symmetrical about the W plane. Multiple inlet channels 303 are provided inside the water distribution device 300, with each inlet end 31 corresponding to and connected to one of the multiple inlet channels 303. All inlet channels 303 are connected to the water distribution chamber 301 and are symmetrically distributed about the W plane. The water distribution device 300 also has two symmetrically arranged water distribution channels, A302 and B302, about the W plane. Water distribution channel A302 connects to outlet end A32, and water distribution channel B302 connects to outlet end B32. This design ensures that the water pressure in water distribution channels A302 and B302 is the same, thus ensuring that the outlet water pressure in outlet end A32 and outlet end B32 is also the same. Corresponding to the above design, each spray head 21 includes an A spray head A21 and a B spray head B21 located on opposite sides (e.g., left and right sides) of the base station base 100. An A water distribution channel A302 is connected to the A spray head A21, and a B water distribution channel B302 is connected to the B spray head B21. This design allows the A spray head A21 and the B spray head B21 to have the same spray pressure, thus enabling the lawnmower cleaning base station to clean opposite sides of the lawnmower chassis to the same degree in practical applications. This improves the cleaning effect of the lawnmower cleaning base station.
