Description

Technical Field

[0001] This application relates to the field of clean technology, and in particular to a tray assembly, base station, and cleaning system. Background Technology

[0002] Cleaning devices such as robotic vacuum cleaners can work with base stations to clean the cleaning components of the robot, such as its rollers or mops, achieving self-cleaning. Taking the roller as an example, to prevent water from splashing out of the base station during cleaning, a tray can be installed on the base station to hold the roller, temporarily storing the dirt generated during cleaning. As dirt accumulates in the tray, some dirt becomes difficult to drain, and the tray can easily accumulate dirt, leading to bacterial growth. Utility Model Content

[0003] This application provides a tray assembly, a base station, and a cleaning system, designed to improve the problem of difficulty in removing dirt from inside the tray.

[0004] To achieve the above technical effects, one technical solution adopted in this application is: providing a tray assembly for a base station, the tray assembly comprising:

[0005] case;

[0006] The pallet body is disposed within the housing; the pallet body forms a cleaning tank, and the cleaning tank is provided with a drain outlet; and

[0007] A spray assembly is disposed in the housing. The spray assembly includes nozzles, and the number of nozzles is at least two sets, which are arranged opposite to each other in the left-right direction along the cleaning tank.

[0008] In this application example, a cleaning tank is provided on the pallet body, and water is sprayed into the cleaning tank using a spray assembly installed on the housing to flush away at least part of the dirt in the pallet and discharge it with the water flow. Furthermore, the spray assembly includes nozzles that are arranged opposite each other in the left-right direction of the cleaning tank to counter-flushing the dirt in the cleaning tank, thereby concentrating the dirt in the pallet towards the central area of ​​the pallet and discharging it promptly with the water flow, preventing the dirt from spreading to the corners or edges of the pallet and improving the cleaning effect.

[0009] This application also provides another example of a tray assembly for a base station, the tray assembly comprising:

[0010] case;

[0011] A tray body is disposed within the housing; the tray body forms a cleaning tank, and the cleaning tank is provided with a drain outlet; and

[0012] A spray assembly is disposed in the housing, the spray assembly including a nozzle, the nozzle being disposed toward the cleaning tank;

[0013] The nozzle includes a spray channel and a water outlet facing the cleaning tank. The spray channel includes an output port. The spray channel is used to pressurize the water flow in the spray assembly and then shoot it out through the output port. The water outlet is used to adjust the shape of the water flow shot out through the output port before shooting it out. In the water outlet direction of the spray assembly, the water outlet is located downstream of the output port.

[0014] In this application example, a cleaning tank is provided on the tray body, and water is sprayed into the cleaning tank using a spray assembly installed on the housing to flush away at least part of the dirt in the tray and discharge it with the water flow. Furthermore, the spray assembly includes a nozzle, which includes a spray channel and a water outlet. The water flow within the spray assembly is pressurized through the spray channel, and the water outlet adjusts the water outlet shape before it is sprayed outwards. By increasing the water flow pressure, the dirt flushing effect in the cleaning tank is improved. By adjusting the water outlet shape, the water coverage area is increased, avoiding the problem of the pressurized water flow shape in the spray channel being too concentrated or dispersed, failing to adapt to the cleaning tank, and resulting in poor cleaning coverage. This improves the dirt flushing effect of the cleaning tank.

[0015] Based on the aforementioned tray assembly, this application also proposes a base station, comprising: a base station body, a water supply assembly, and the tray assembly as described above; the water supply assembly and the tray assembly are disposed on the base station body, and the water supply assembly is used to supply water to the spray assembly; wherein, the base station further comprises a heating assembly, which is used to heat the water in the water supply assembly or the spray assembly.

[0016] In this example, a water supply component supplies water to the spray component, which then rinses the cleaning tank through the nozzles to remove dirt from the tray, thus improving the cleanliness of the base station cleaning tank. Simultaneously, heating the water further enhances the dissolving effect, further improving the cleaning efficiency of the tray.

[0017] Based on the aforementioned base station, this application also proposes a cleaning system, which includes a cleaning robot and the base station as described above. The cleaning robot is used to perform self-cleaning through the base station.

[0018] In this example, the cleaning robot can perform self-cleaning through the cleaning system. Since the water supply component can supply water to the spray component, after the cleaning robot completes self-cleaning, it can rinse the cleaning tank through the nozzles of the spray component to improve the problem of dirt accumulating in the cleaning tank and not being able to be discharged.

[0044] Please see Figure 1 and Figure 2The base station 100 can be used to dock and temporarily store cleaning equipment, such as sweepers, mops, sweeper-mop combos, or other devices capable of cleaning surfaces like floors or carpets. Taking a sweeper as an example, when the sweeper is docked at the base station 100, its rollers can be cleaned through the base station 100. The resulting dirt can be temporarily stored at the base station 100 or discharged to a designated location via a pipe. A tray assembly 10 can be installed on the base station 100. When cleaning the sweeper's rollers, the tray assembly 10 can hold the rollers to prevent dirt from splashing out of the base station 100. After cleaning, the tray assembly 10 can also be used to temporarily store the dirt.

[0045] However, since the dirt generated after cleaning components such as rollers contain hair, mud, oil and other dirt, the tray assembly 10 may accumulate dirt during long-term use and cannot be discharged.

[0046] Please see Figures 2 to 7 This application addresses the problem of dirt accumulation in the tray body 11 by proposing an example of a tray assembly 10. The tray assembly 10 can be used in a base station 100. The tray assembly 10 includes a housing 13, a tray body, and a spray assembly 120. The tray body 11 is disposed on the housing 13. The tray body 11 forms a cleaning tank 113, and the cleaning tank 113 is provided with a drain outlet 114. The spray assembly 120 is disposed on the housing 13 and includes nozzles 12. The number of nozzles 12 is at least two sets, and the at least two sets of nozzles 12 are arranged opposite each other in the left-right direction along the cleaning tank 113.

[0047] The tray body 11 has a cleaning tank 113, which can be used to hold cleaning components such as rollers to clean the rollers; when cleaning the rollers, the dirt generated during cleaning can be temporarily stored in the cleaning tank 113.

[0048] The housing 13 can serve as an intermediate connector between the tray body 11 and the base station 100. When the tray body 11 needs to be installed, the housing 13 can be connected to the base station 100 first, and then the tray body 11 can be installed on the housing 13. Alternatively, the tray body 11 and the housing 13 can be installed together, and then both can be directly and integrally installed on the base station 100. In some examples, the housing 13 can be integrally set with the tray body 11. In some examples, the housing 13 and the tray body 11 are separately set and connected to each other. The housing 13 can be used to support the tray body 11, and the housing 13 can be provided with a docking structure for engaging with the tray body 11. The docking structure can be a snap, a protrusion, a groove, or other structure that can limit the position of the tray body 11.

[0049] The tray body 11 is mounted on the housing 13. The tray body 11 is used to accommodate the rollers and the dirt generated during the cleaning of the rollers. The tray body 11 includes a tray bottom 111 and a surrounding edge 112. The tray bottom 111 can form the bottom wall of the tray body 11. When the tray body 11 is mounted on a base station, the tray bottom 111 can be parallel to the horizontal plane. Optionally, the tray bottom 111 can also be inclined at a certain angle relative to the horizontal plane. The surrounding edge 112 is connected to the tray bottom 111 and surrounds the edge of the tray bottom 111 so that the surrounding edge 112 and the tray bottom 111 can form a cleaning groove 113, which can be used to accommodate the rollers and dirt. In this example, the shape of the cleaning groove 113 can be adapted to the shape of the rollers. The cleaning groove 113 is provided with a drain outlet 114, which can be a through hole penetrating the tray body 11.

[0050] The spray assembly 120 is used to spray water into the cleaning tank 113. The spray assembly 120 may include a nozzle 12, which is mounted on the housing 13. In some examples, the spray assembly 120 may also include a pipe connected to the nozzle 12 and a valve body or other structure disposed on the pipe.

[0051] The cleaning tank 113 is provided with nozzles 12 on both sides in the left and right direction, and the nozzles 12 on the left and right sides of the cleaning tank 113 are arranged opposite to each other, so as to rinse the inner wall surface of the cleaning tank 113 from both sides in the left and right direction through the nozzles 12.

[0052] Spray nozzles 12 spray water into the cleaning tank 113 from both the left and right sides, allowing the water flow to clean the inner wall of the cleaning tank 113. The cleaned dirt can then be discharged through the drain port 114. In this example, by installing spray nozzles 12 on both the left and right sides of the cleaning tank 113, water can be input from both sides, allowing the water flow to cover a larger area within the cleaning tank 113, reducing cleaning dead zones and improving the cleaning efficiency of the cleaning tank 113. Since the spray nozzles 12 on both sides can create opposing water flows within the cleaning tank 113, the accumulation of impurities within the cleaning tank 113 can be reduced, facilitating the removal of impurities. In some examples, at least two spray nozzles can be installed on each of the left and right sides of the cleaning tank 113 to increase the water volume and accelerate the flow of impurities.

[0053] During the operation of the cleaning robot, its rollers may accumulate particulate matter such as hair and sand, as well as foreign objects such as oil stains. After the rollers are cleaned in the cleaning tank 113, these foreign objects may remain on the inner wall and corners of the cleaning tank 113. In this example, by using nozzles 12 to spray water into the cleaning tank 113, the water flow can propel the foreign objects towards the drain outlet 114, reducing the possibility of foreign objects accumulating in the cleaning tank 113 and forming stubborn stains that are difficult to remove. In this example, nozzles 12 are installed on both the left and right sides of the cleaning tank 113, which can create a convection current. The water flow sprayed from the left and right sides of the cleaning tank 113 can agitate the impurities at the edges and corners of the cleaning tank 113, and collect them with the dirt towards the central area of ​​the cleaning tank. The large volume of water at the collection point can dissolve and carry away more dirt, which is then discharged with the water flow.

[0054] To further improve the sewage discharge effect, in this example, the sewage outlet is positioned away from the left and right ends of the cleaning tank. Since the nozzles are located at the left and right ends of the cleaning tank, the water flow from the nozzles will accumulate at a position away from the left and right ends. Therefore, positioning the sewage outlet away from the left and right ends makes it easier for impurities to be discharged from the sewage outlet 114. In this example, the nozzles 12 on the left and right sides of the cleaning tank 113 spray water flow, making it easier for the water flow in both directions to converge at the edge of the cleaning tank 113 to form a vortex. This accelerates the participation of impurities at the edges and corners of the cleaning tank 113 in the water flow, making it less likely for impurities to accumulate at the edges and corners of the cleaning tank 113, thereby further improving the cleaning efficiency of impurities.

[0055] In some examples, the drain outlet 114 is positioned away from the left and right ends of the cleaning tank 113. In this example, by positioning the drain outlet 114 away from the left and right ends of the cleaning tank 113, the drain outlet 114 can be positioned away from the nozzles 12 on the left and right sides of the cleaning tank 113. The water jets from the nozzles 12 can cover a wider area of ​​the inner wall of the cleaning tank 113, and dirt can flow along the inner wall of the cleaning tank 113 towards the drain outlet 114. During the flow of water and dirt, impurities on the inner wall of the cleaning tank 113 can be flushed towards the drain outlet 114, thereby improving the utilization efficiency of the water flow.

[0056] In some examples, at least a portion of the cleaning tank 113 is recessed to form a drain outlet 114; in this example, the bottom 111 of the tray may be partially recessed to form the drain outlet 114, to facilitate the formation of the drain outlet 114. Because the bottom 111 of the tray is partially recessed, dirt and impurities can be guided through the recessed deformation portion, thereby reducing the possibility of impurities and dirt accumulating in the cleaning tank 113.

[0057] In some examples, a filter element 115 is provided inside the drain outlet 114. The filter element 115 is used to filter impurities at the drain outlet 114 to reduce the possibility of clogging the drain outlet 114. The filter element 115 can be a mesh structure or other structure with through holes that can filter dirt.

[0058] In some examples, the nozzle 12 includes a spray channel 121 and an outlet 126 facing the cleaning tank 113. The outlet 1211 of the spray channel 121 is connected to the outlet 126. The spray channel 121 includes an outlet 1211. The spray channel 121 is used to pressurize the water flow in the spray assembly 120 and then eject it outward through the outlet 1211. The outlet 126 is used to adjust the shape of the water flow ejected from the outlet 1211 and then eject it outward. In the water outlet direction of the spray assembly 120, the outlet 126 is located downstream of the outlet 1211.

[0059] The nozzle 12 provided in this application example includes a spray channel 121, through which water flow is pressurized to enhance the scouring effect of the water flow. The pressurization of the water flow through the spray channel 121 can be based on fluid dynamics principles, by gradually decreasing the outlet cross-sectional area of ​​the spray channel 121 along the water flow direction, thereby increasing the water flow pressure. The pressurized water flow is ejected outward through the outlet 1211 of the spray channel 121. The outlet 1211 of the spray channel 121 in this application can be, for example, a nozzle, through which the pressurized water flow is ejected outward.

[0060] Furthermore, the nozzle 12 of this application also includes a water outlet 126, which can be a separate water outlet component located downstream of the spray channel and connected to the output port of the spray channel, i.e., the nozzle. The water outlet component is used to further adjust the shape of the water flow ejected from the nozzle so that the shape of the ejected water flow is adapted to the cleaning tank. For example, the water outlet width can be adjusted to match the width of the cleaning tank; further, the water outlet angle can be adjusted so that the water outlet angle is within a certain angle range, such as within 20 degrees up and down, which can improve the concentration of water flow and further improve the dirt flushing effect; further, the water outlet surface can be adjusted so that the upper and lower ends of the water outlet surface are flat, which can further improve the dirt flushing effect, while avoiding water splashing caused by the water outlet surface not being flat, which would cause dirt to be flushed out of the cleaning tank and contaminate other parts of the base station or cause pollution to the user's home.

[0061] Furthermore, in the water outlet direction of the spray channel 121, the cross-sectional area of ​​the outlet 126 gradually increases in the direction perpendicular to the central axis of the outlet 126. The spray channel 121 is used to output water flow. The outlet 126 is a hollow channel on the nozzle 12 facing the cleaning tank 113. The output port of the spray channel 121 can be connected to a water source, and the output port 1211 of the spray channel 121 is connected to the outlet 126. In the water outlet direction of the spray channel 121, the cross-sectional area of ​​the outlet 126 gradually increases in the direction perpendicular to the central axis of the outlet 126, so that the water flow output from the output port 1211 of the spray channel 121 is distributed in a fan shape, thereby increasing the effective area of ​​the water flow output, allowing the water flow to radiate to the inner surface of the cleaning tank 113, cleaning the inner surface of the cleaning tank 113 through the water flow and reducing the problem of bacterial growth in the cleaning tank 113. Because the outlet 126 has a gradually increasing cross-sectional area, the water flow radiates over a larger area, reducing the problem of numerous cleaning dead spots in the cleaning tank 113 caused by the overly concentrated position of the sprayed water flow, thereby improving the cleaning effect of the tray body 11. In this example, the water flow first enters the spray channel 121. Since the shape of the outlet 1211 of the spray channel 121 is usually relatively fixed and difficult to adjust according to actual needs, the water flow is pressurized in the spray channel 121 and then output to the outlet 126. This application sets the outlet 126 outside the outlet 1211 of the spray channel 121. The outlet 126 can further constrain and restrict the shape and angle of the water flow output from the outlet 1211 of the spray channel 121, that is, further shape the shape of the water flow. This makes the output shape and angle of the water flow more consistent with the shape and size of the cleaning tank 113, which can better wash away the dirt on the cleaning tank 113 and greatly improve the washing coverage and washing effect.

[0062] In some examples, the central axis of the outlet 126 of the nozzle 12 is inclined downwards; the central axis of the outlet 126 of the nozzle 12 is a straight line connecting the geometric center of the inlet and outlet of the outlet 126. In this example, the central axis of the outlet 126 of the nozzle 12 is inclined downwards, so that the water flow output by the nozzle 12 can be sprayed downwards at an angle onto the surface of the cleaning tank 113. On the one hand, it can concentrate the water flow towards the inner wall of the cleaning tank to increase the impact force of the water flow on the impurities on the inner wall of the cleaning tank 113. On the other hand, it can reduce the problem of water splashing out of the tray body 11 due to the excessively high water flow angle of the nozzle 12.

[0063] In some examples, the water outlet 126 is angled downwards. In this example, the water outlet 126 is angled downwards to concentrate the water flow onto the inner wall of the cleaning tank 113, reducing the problem of water splashing outwards.

[0064] In some examples, the spray channel 121 has an outlet 1211, the inner annular wall 1212 of which is at least partially elliptical. The elliptical shape of the outlet 1211 allows the water flow from the spray channel 121 to radiate in a fan shape, thereby increasing the coverage area of ​​the water flow and improving the cleaning efficiency of the cleaning tank 113. The elliptical shape of the inner annular wall 1212 of the outlet 121 means that when the nozzle 12 is projected onto a horizontal plane, the outline of the outlet 1211 in the projection plane is at least partially elliptical.

[0065] In some examples, the major axis of the ellipse containing the inner ring wall 1212 of the outlet 1211 is arranged along the horizontal direction of the cleaning tank 113. In this example, by making the major axis of the ellipse containing the inner ring wall 1212 of the outlet 1211 parallel to the cleaning tank 113, the water flow output from the outlet 1211 can radiate more along a direction parallel to the cleaning tank 113 onto the inner wall surface of the cleaning tank 113, thereby increasing the coverage area of ​​the water flow.

[0066] In some examples, the maximum opening distance of the output port does not exceed 0.35 mm. The output port 1211 includes an upper end face and a lower end face, and the maximum distance between the upper and lower end faces does not exceed 0.35 mm. In this example, by limiting the distance between the upper and lower end faces of the output port, the maximum opening of the output port 1211 can be limited, thereby facilitating the control of the water flow rate in the spray channel 121 and improving the cleaning effect of the nozzle 12. In some examples, the distance between the upper and lower end faces of the output port can be 0.25 mm, 0.3 mm, 0.35 mm, or any other value within the above range. In this application example, the corresponding numerical range can be selected according to the type of water flow being sprayed. The water flow in this application can be clean water or cleaning fluid.

[0067] Please see Figure 10In some examples, the outlet 126 has a horizontal water outlet angle less than or equal to 120°. The horizontal water outlet angle of the outlet 126 is β, where β does not exceed 120°. In this example, the width of the outlet 126 gradually increases from the output port 1211 of the jet channel 121 towards the outlet 126, forming a gradually expanding jet channel. By limiting the horizontal water outlet angle of the output port 1211, the maximum horizontal jet width of the outlet 126 can be limited. On the one hand, this limits the range of the jet width of the water flow output from the outlet 126, allowing the water flow to act more on the inner wall of the cleaning tank 113. On the other hand, it facilitates the control of the rinsing intensity of the water flow output from the outlet 126, reducing the problem of reduced output water velocity due to excessive width of the outlet 126 in the horizontal direction. In this example, the horizontal water outlet angle β of the outlet 126 can be 90°, 100°, 110°, 120° or any value within the above range. In this example, the specific range of the included angle β can be determined based on the width of the tray body 1111 along the horizontal direction.

[0068] In some examples, in the water outlet direction of the nozzle 12, the outlet 126 is located downstream of the output port 1211, and the outlet 126 is located adjacent to the output port 1211; wherein, the width of the outlet 126 is greater than the width of the output port 1211. In this example, by making the width of the outlet 126 greater than the width of the output port 1211, the maximum radiation range of the outlet 126 in the width direction can be easily controlled, so that the radiation range of the water flow output from the outlet 126 is controlled within the cleaning tank 113, thereby reducing the possibility of water splashing out of the cleaning tank 113.

[0069] In some examples, the outlet 126 includes an upper outlet end 1261 and a lower outlet end 1262, both of which are planar, and the angle between the upper outlet end 1261 and the lower outlet end 1262 does not exceed 25°. In this example, by limiting the angle between the upper outlet end 1261 and the lower outlet end 1262 of the outlet 126, the maximum spray height of the spray channel 121 in the output direction can be limited. On the one hand, this limits the spray height of the water flow output by the spray channel 121, allowing the water flow to act more on the inner wall of the cleaning tank 113. On the other hand, it facilitates the control of the rinsing intensity of the water flow output by the spray channel 121, reducing the problem of reduced output water velocity due to excessive output height of the spray channel 121. In this example, the angle α between the upper outlet end 1261 and the lower outlet end 1262 can be 15°, 18°, 20°, 22°, 25°, or any value within the above range.

[0070] In some examples, the nozzle 12 includes a first housing 122 and a second housing 123. The first housing 122 has a first groove 1221, and the second housing 123 has a second groove 1231. The second housing 123 is mounted on the first housing 122, and the first groove 1221 and the second groove 1231 enclose and form a spray channel 121. In the water outlet direction of the nozzle 12, the cross-sectional area of ​​the spray channel 121 gradually decreases in the direction perpendicular to the central axis of the spray channel 121.

[0071] In this example, the first housing 122 and the second housing 123 are combined to form the nozzle 12, which facilitates the separate molding and assembly of the first housing 122 and the second housing 123. This allows for easy mold making and facilitates the formation of a pre-shaped spray channel 121 within the nozzle 12. The first groove 1221 is a groove formed on the first housing 122, and the second groove 1231 is a groove formed on the second housing 123. Optionally, the depth of at least one of the first groove 1221 and the second groove 1231 can be gradually varied so that the combination of the first groove 1221 and the second groove 1231 can form a spray channel 121 with a gradually changing cross-section. In this example, the first housing 122 and the second housing 123 can be connected and fixed to each other by snap-fit, pin-fit, screw connection, or other means.

[0072] At least one of the first housing 122 and the second housing 123 is mounted on the housing 13. In this example, the second housing 123 is mounted on the housing 13. The second housing 123 can be directly connected and fixed to the housing 13, or the second housing 123 can be fixed to the housing 13 through an intermediate connector. In some examples, the tray assembly 10 also includes a housing 13, and the second housing 123 can be connected to the housing 13.

[0073] In this example, in the water outlet direction of the nozzle 12, the cross-sectional area of ​​the spray channel 121 gradually decreases in the direction perpendicular to the central axis of the spray channel 121, so that one end of the spray channel 121 can form a constriction shape. When the water flows from the spray channel 121 into the outlet 126, it can be pressurized to form a jet state, which helps to increase the output speed of the water flow, so as to facilitate the control of the flow rate and velocity of the water delivered to the spray channel 121 and improve the flushing effect of the water flow on the cleaning tank 113.

[0074] In some examples, the first housing 122 and the second housing 123 can be joined together in the vertical direction to form the nozzle 12, or the first housing 122 and the second housing 123 can be joined together in the front-back direction to form the nozzle 12.

[0075] In some examples, the first housing 122 is also provided with a third groove 1222 that communicates with the first groove 1221, and the second housing 123 is also provided with a fourth groove 1232 that communicates with the second groove 1231. The third groove 1222 and the fourth groove 1232 together form an input flow channel 124 that communicates with the injection channel 121.

[0076] The third groove 1222 is a groove formed on the first housing 122, and the third groove 1222 connects to the first groove 1221. The fourth groove 1232 is a groove formed on the second housing 123, and the fourth groove 1232 connects to the second groove 1231. When the first housing 122 and the second housing 123 are connected, the third groove 1222 and the fourth groove 1232 are connected to each other and enclose to form an input channel 124, which can be used to connect to a water source. Optionally, at least one of the first housing 122 and the second housing 123 can be provided with a connector 125 connecting to the input channel 124, which can be used to connect to a water source. In this example, the input channel 124 can be used to store water flow to facilitate control of the flow rate and flow of the nozzle 12. Optionally, the input channel 124 can also serve as a cavity for mixing cleaning substances and water to improve the uniformity of the output water flow.

[0077] In some examples, the nozzle 12 also has an input channel 124 connecting the spray channel 121 and the outside of the nozzle 12. Along the water outlet direction of the nozzle 12, the inner diameter of the spray channel 121 near the outlet 126 gradually decreases. The input channel 124 in this example can be used to connect to a water source. Optionally, the input channel 124 can be formed by enclosing the first housing 122 and the second housing 123 in any of the above examples. The input channel 124 has a front end and a rear end. The front end of the input channel 124 is connected to the inlet of the spray channel 121, and the rear end of the input channel 124 is away from the inlet of the spray channel 121. From the rear end to the front end, the cross-sectional area of ​​the spray channel 121 gradually decreases so that one end of the spray channel 121 can form a constricted shape, so as to facilitate the control of the flow rate and velocity of the water delivered to the spray channel 121.

[0078] This application also provides an embodiment of a tray assembly for a base station. The tray assembly includes: a housing; a tray body disposed on the housing; the tray body forming a cleaning tank with a drain outlet; and a spray assembly disposed on the housing. The spray assembly includes a nozzle facing the cleaning tank. The nozzle includes a spray channel and a water outlet facing the cleaning tank. The spray channel includes an output port. The spray channel pressurizes the water flow in the spray assembly and ejects it outward through the output port. The water outlet adjusts the shape of the water flow ejected from the output port before ejecting it outward. In the water outlet direction of the spray assembly, the water outlet is located downstream of the output port.

[0079] For details, please refer to Figures 2 to 7 This application addresses the problem of dirt accumulation in the tray body 11 by proposing an example of a tray assembly 10. The tray assembly 10 can be used in a base station 100. The tray assembly 10 includes a housing 13, a tray body, and a spray assembly 120. The tray body 11 is disposed on the housing 13. The tray body 11 forms a cleaning tank 113, and the cleaning tank 113 is provided with a drain outlet 114. The spray assembly 120 is disposed on the housing 13 and includes a nozzle 12, which is arranged toward the cleaning tank 113.

[0080] The tray body 11 has a cleaning tank 113, which can be used to hold cleaning components such as rollers to clean the rollers; when cleaning the rollers, the dirt generated during cleaning can be temporarily stored in the cleaning tank 113.

[0081] In some examples, the nozzle 12 includes a spray channel 121 and an outlet 126 facing the cleaning tank 113. The outlet 1211 of the spray channel 121 is connected to the outlet 126. The spray channel 121 includes an outlet 1211. The spray channel 121 is used to pressurize the water flow in the spray assembly 120 and then eject it outward through the outlet 1211. The outlet 126 is used to adjust the shape of the water flow ejected from the outlet 1211 and then eject it outward. In the water outlet direction of the spray assembly 120, the outlet 126 is located downstream of the outlet 1211.

[0082] The nozzle provided in this application includes a spray channel that pressurizes the water flow to enhance its scouring effect. The pressurization of the water flow can be achieved based on fluid dynamics principles, by gradually decreasing the outlet cross-sectional area of ​​the spray channel along the water flow direction, thereby increasing the water pressure. The pressurized water flow is then ejected outward through the outlet of the spray channel. The outlet of the spray channel in this application can be, for example, a nozzle, through which the pressurized water flow is ejected outward.

[0083] Furthermore, the nozzle of this application also includes a water outlet, which can be a separate water outlet component located downstream of the spray channel and connected to the output port of the spray channel, i.e., the nozzle. The water outlet component is used to further adjust the shape of the water flow ejected from the nozzle so that the shape of the ejected water flow is adapted to the cleaning tank. For example, the water outlet width can be adjusted to match the width of the cleaning tank; further, the water outlet angle can be adjusted so that the water outlet angle is within a certain angle range, such as within 20 degrees up and down, which can improve the concentration of water flow and further improve the dirt flushing effect; further, the water outlet surface can also be adjusted so that the upper and lower ends of the water outlet surface are flat, which can further improve the dirt flushing effect, while avoiding water splashing caused by the water outlet surface not being flat, which would cause dirt to be flushed out of the cleaning tank and contaminate other parts of the base station or cause pollution to the user's home.

[0084] Furthermore, the water outlet includes an upper water outlet end and a lower water outlet end, both of which are planar, and the angle between the upper water outlet end and the lower water outlet end does not exceed 25°.

[0085] Specifically, in some examples, the water outlet 126 includes an upper water outlet end 1261 and a lower water outlet end 1262, both of which are planar, and the angle between the upper water outlet end 1261 and the lower water outlet end 1262 does not exceed 25°. In this example, by limiting the angle between the upper water outlet end 1261 and the lower water outlet end 1262 of the water outlet 126, the maximum spray height of the spray channel 121 in the output direction can be limited. On the one hand, this limits the spray height of the water flow output by the spray channel 121, allowing the water flow to act more on the inner wall surface of the cleaning tank 113. On the other hand, it facilitates the control of the rinsing intensity of the water flow output by the spray channel 121, reducing the problem of reduced output water velocity due to excessive output height of the spray channel 121. In this example, the angle α between the upper water outlet end 1261 and the lower water outlet end 1262 can be 15°, 18°, 20°, 22°, 25°, or any value within the above range.

[0086] In the water outlet direction of the spray assembly, the cross-sectional area of ​​the outlet gradually increases in the direction perpendicular to the central axis of the outlet.

[0087] Specifically, in the water outlet direction of the spray channel 121, the cross-sectional area of ​​the outlet 126 gradually increases in the direction perpendicular to the central axis of the outlet 126. The spray channel 121 is used to output water flow. The outlet 126 is a hollow channel on the nozzle 12 facing the cleaning tank 113. The output port of the spray channel 121 can be connected to a water source, and the output port 1211 of the spray channel 121 is connected to the outlet 126. In the water outlet direction of the spray channel 121, the cross-sectional area of ​​the outlet 126 gradually increases in the direction perpendicular to the central axis of the outlet 126, so that the water flow output from the output port 1211 of the spray channel 121 is distributed in a fan shape, thereby increasing the effective area of ​​the water flow output, allowing the water flow to radiate to the inner surface of the cleaning tank 113, cleaning the inner surface of the cleaning tank 113 through the water flow and reducing the problem of bacterial growth in the cleaning tank 113. Because the outlet 126 has a gradually increasing cross-sectional area, the water flow radiates over a larger area, reducing the problem of numerous cleaning dead spots in the cleaning tank 113 caused by the overly concentrated position of the sprayed water flow, thereby improving the cleaning effect of the tray body 11. In this example, the water flow first enters the spray channel 121. Since the shape of the outlet 1211 of the spray channel 121 is usually relatively fixed and difficult to adjust according to actual needs, the water flow is pressurized in the spray channel 121 and then output to the outlet 126. This application sets the outlet 126 outside the outlet 1211 of the spray channel 121. The outlet 126 can further constrain and restrict the shape and angle of the water flow output from the outlet 1211 of the spray channel 121, that is, further shape the shape of the water flow. This makes the output shape and angle of the water flow more consistent with the shape and size of the cleaning tank 113, which can better wash away the dirt on the cleaning tank 113 and greatly improve the washing coverage and washing effect.

[0088] Furthermore, in this example, the outlet is positioned immediately adjacent to the output outlet, and the width of the outlet is greater than the width of the output outlet. The outlet has a horizontal water outlet angle, which is less than or equal to 120°.

[0089] Please see Figure 10In some examples, the outlet 126 has a horizontal water outlet angle less than or equal to 120°. The horizontal water outlet angle of the outlet 126 is β, where β does not exceed 120°. In this example, the width of the outlet 126 gradually increases from the output port 1211 of the jet channel 121 towards the outlet 126, forming a gradually expanding jet channel. By limiting the horizontal water outlet angle of the output port 1211, the maximum horizontal jet width of the outlet 126 can be limited. On the one hand, this limits the range of the jet width of the water flow output from the outlet 126, allowing the water flow to act more on the inner wall of the cleaning tank 113. On the other hand, it facilitates the control of the rinsing intensity of the water flow output from the outlet 126, reducing the problem of reduced output water velocity due to excessive width of the outlet 126 in the horizontal direction. In this example, the horizontal water outlet angle β of the outlet 126 can be 90°, 100°, 110°, 120° or any value within the above range. In this example, the specific range of the included angle β can be determined based on the width of the tray body 1111 along the horizontal direction.

[0090] In some examples, in the water outlet direction of the nozzle 12, the outlet 126 is located downstream of the output port 1211, and the outlet 126 is located adjacent to the output port 1211; wherein, the width of the outlet 126 is greater than the width of the output port 1211. In this example, by making the width of the outlet 126 greater than the width of the output port 1211, the maximum radiation range of the outlet 126 in the width direction can be easily controlled, so that the radiation range of the water flow output from the outlet 126 is controlled within the cleaning tank 113, thereby reducing the possibility of water splashing out of the cleaning tank 113.

[0091] Please see Figure 11 and Figure 12In some examples, the housing 13 has a suction channel 131 that connects the drain port 114 to the outside of the housing 13. The housing 13 can be used to support the tray body 11 so that the tray body 11 can be installed at a preset position on the base station 100. In this example, the tray body 11 can be installed at a preset position above the housing 13. The suction channel 131 is provided on the housing 13 for the flow of dirt. The suction channel 131 connects the drain port 114 to the outside of the housing 13 so that dirt in the cleaning tank 113 can be discharged to the outside of the tray assembly 10 through the drain port 114 and the suction channel 131. In this example, the suction channel 131 can be a channel formed by a partially hollow area on the housing 13. Optionally, a pipe can be provided on the housing 13 to form the suction channel 131. In some examples, a negative pressure device as described in the above example is provided outside the tray body 11. The negative pressure device can be connected to the drain port 114 through the suction channel 131. In some examples, the working time of the negative pressure device can be determined based on the water output of the nozzle 12; in some examples, the working time of the negative pressure device can be determined based on the water level in the cleaning tank 113; in some examples, the working time of the negative pressure device can be determined based on the cleaning requirements of the roller, including the cleanliness of the roller. For example, the required cleaning time and water consumption will differ depending on whether the roller is being cleaned simply or deeply. When deep cleaning is being performed, the roller stays in the cleaning tank 113 for a longer time. In this case, the start time of the negative pressure device can be delayed accordingly, and the negative pressure device can be started to pump water when the roller has finished cleaning.

[0092] In some examples, the housing 13 is at least partially recessed downwards to form a recess 134, with the drain outlet 114 embedded within it, and the suction channel 131 connected to the recess 134. The recess 134, formed by the downward indentation on the housing 13 corresponding to the drain outlet 114, serves two purposes: firstly, it accommodates the drain outlet 114 and provides initial positioning for the tray body 11 and the housing 13, limiting the displacement of the tray body 11 relative to the housing 13; secondly, it accommodates the dirt discharged from the drain outlet 114, allowing dirt in the collection trough 1141 to flow into the recess 134 through the drain outlet 114. The suction channel 131 connects to the recess 134, allowing dirt to enter the suction channel 131 via the recess 134.

[0093] In some examples, the housing 13 is provided with a first pipe 132 and a second pipe 133 connected to the first pipe 132. The end of the first pipe 132 away from the second pipe 133 is connected to a settling tank 134, and the end of the second pipe 133 away from the first pipe 132 is connected to the outside of the housing 13. The first pipe 132 and the second pipe 133 are connected to form a suction channel 131. The first pipe 132 is connected to the settling tank 134 so that dirt in the settling tank 134 can be discharged to the outside through the first pipe 132. The second pipe 133 is connected to the first pipe 132 and the outside of the housing 13. In this example, the first pipe 132 can be a bent pipe, a straight pipe, or a combination thereof. By setting the first pipe 132, the first pipe 132 can serve as an intermediate connecting pipe between the second pipe 133 and the settling tank 134, so as to facilitate the setting of the suction channel 131 and make the position of the suction channel 131 compatible with that of the settling tank 134. The first pipe 132 and the second pipe 133 can be plugged into each other. In some examples, the second pipe 133 can be integrally formed with the housing 13. In this example, by using multiple pipe segments to form the suction channel 131, the position of the suction channel 131 can correspond to the shape of the housing 13, reducing the difficulty of connecting the suction channel 131 and the settling tank 134. In some examples, a third pipe 135 can also be provided outside the housing 13. The third pipe 135 is connected to the end of the second pipe 133 away from the first pipe 132, and the third pipe 135 can be connected to a negative pressure device outside the housing 13.

[0094] Please see Figure 1 This application also proposes an example of a base station 100, which includes a base station body 20, a water supply component 30, and a tray component 10 as in any of the above examples. The water supply component 30 and the tray component are disposed on the base station body 20, and the tray component 10 is installed on the base station body 20. The water supply component 30 is used to supply water to the spray component 120.

[0095] The base station 100 can be used to dock cleaning equipment such as sweepers, and can also be used to charge the cleaning equipment. The tray assembly 10 is installed below the base station body 20 so that when the cleaning equipment is docked on the base station 100, the tray body 11 can be used to hold cleaning components such as the rollers of the cleaning equipment. When cleaning the rollers and other cleaning components, dirt can be held by the tray body 11.

[0096] Please see Figure 13In some examples, the base station 100 also includes a water supply assembly 30, which is mounted on the base station body 20 or the tray assembly 10. The water supply assembly 30 is connected to the nozzle 12 and is used to supply water to the nozzle 12. The water supply assembly 30 can be mounted on the base station body 20 or the tray assembly 10. Taking the water supply assembly 30 mounted on the base station body 20 as an example, the water supply assembly 30 can include a water tank and a water pump, which can supply water to the nozzle 12. In some examples, the water supply assembly 30 can also include a water flow tank for storing cleaning materials, and the water supply assembly 30 can be used to pump the liquid in the water tank and the water flow tank into the nozzle 12.

[0097] In some examples, the base station 100 also includes a heating component 40, which is disposed on the base station body 20. The heating component 40 is used to heat the water in the water supply component 30 or the spray component 120. The heating component 40 heats the water delivered to the spray nozzle 12, and by spraying hot water, impurities can be dissolved more quickly, improving the cleaning effect of the water flow. The heating component 40 can be installed on the base station body 20 or the tray component 10. In this example, the heating component 40 can be integrated into the water supply component 30.

[0098] This application also proposes another example of a tray assembly 10 for use in a base station. The tray assembly 10 includes a tray housing 13, a tray body 11, and a spray assembly 120. The tray body 120 is disposed on the housing 13. The tray body 11 forms a cleaning tank 113, and the cleaning tank 113 is provided with a drain outlet 114. The spray assembly 120 is disposed on the housing 13 and includes a nozzle 12, which is disposed toward the cleaning tank 113. The nozzle 12 includes a spray channel 121 and a water outlet 126 disposed toward the cleaning tank 113. The water outlet 126 is connected to the output port 1211 of the spray channel 121. In the water outlet direction of the nozzle 12, the cross-sectional area of ​​the water outlet 126 gradually increases in the direction perpendicular to the central axis of the water outlet 126.

[0099] The structure and installation method of the shell 13 and the tray body 11 in this example are the same as those in the previous example, and will not be repeated here.

[0100] The end of the spray channel 121 of the nozzle 12 furthest from the outlet 126 can be connected to a water source. The central axis of the outlet 126 of the nozzle 12 is a straight line connecting the geometric center of the inlet and outlet of the outlet 126. This allows the water flow from the outlet 1211 of the spray channel 121 to be distributed in a fan shape, thereby increasing the effective area of ​​the water flow and enabling the water flow to radiate to the inner surface of the cleaning tank 113. This cleans the inner surface of the cleaning tank 113 and reduces the problem of bacterial growth within the cleaning tank 113. Because the outlet 126 has a gradually increasing cross-sectional area, the area radiated by the water flow is larger, reducing the problem of numerous cleaning dead spots within the cleaning tank 113 caused by overly concentrated water flow, thus improving the cleaning effect of the tray body 11. In this example, the water first enters the spray channel 121. Since the shape of the outlet 1211 of the spray channel 121 is usually fixed and difficult to adjust according to actual needs, the water is pressurized in the spray channel 121 and then output to the outlet 126. This application sets the outlet 126 outside the outlet 1211 of the spray channel 121. The outlet 126 can further constrain and restrict the shape and angle of the water output from the outlet 1211 of the spray channel 121, that is, further shape the shape of the water flow. This makes the output shape and angle of the water flow more consistent with the shape and size of the cleaning tank 113, which can better wash the dirt on the cleaning tank 113 and greatly improve the washing coverage and washing effect.

[0101] In some examples, multiple nozzles 12 may be provided on the cleaning tank 113, and the multiple nozzles 12 may be arranged at intervals along the outer periphery of the cleaning tank 113. Optionally, at least one nozzle may be provided on each side of the cleaning tank 113 along its length to flush impurities in the cleaning tank 113 toward the drain port 114 by spraying simultaneously or intermittently from both sides of the cleaning tank 113 along its length.

[0102] This application also provides an example of a cleaning system, which includes a cleaning robot and a base station 100 as in any of the examples above. The cleaning robot may include cleaning equipment such as a sweeping robot, a mopping robot, or a combined sweeping and mopping robot. The base station 100 can be used to dock the cleaning equipment and can also be used to charge or refill the cleaning equipment with water.

[0103] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
