Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a tray structure, a cleaning base station, and a cleaning device. Background Technology

[0002] With the development of intelligent cleaning technology, robotic vacuum cleaners are entering more and more homes, greatly reducing the labor involved in house cleaning. To achieve more effective cleaning, many robotic vacuum cleaners are equipped with mopping functions. While these improve cleaning results to some extent, they also bring the hassle of washing the mop cloth. To solve this problem, robotic vacuum cleaners are usually used in conjunction with a cleaning station. After mopping, the robotic vacuum cleaner can automatically return to the cleaning station to wash or refill the mop cloth. During the self-cleaning process inside the cleaning station, the wastewater suction nozzle on the tray at the bottom of the station promptly sucks away the wastewater, improving cleaning effectiveness and efficiency; however, the suction nozzle generates considerable noise during the wastewater suction process.

[0003] Currently, to address the noise issue caused by suction nozzles during sewage suction, two methods exist: one is to reduce noise by changing the size and shape of the nozzle, and the other is to cover the outside of the nozzle with decorative covers or other materials to block noise. However, the noise reduction method of changing the size and shape of the nozzle is not only ineffective in reducing suction noise, but also affects suction efficiency and is prone to clogging, making it difficult to effectively screen out larger particles. In addition, the noise reduction method of covering the outside of the nozzle with decorative covers or other materials has a complex structure, high cost, and is difficult to install and clean after dirt accumulates. Summary of the Invention

[0004] The purpose of this application is to provide a tray structure, a cleaning base station, and a cleaning device that can reduce noise during sewage pumping while also having good pumping efficiency.

[0005] To achieve the above objectives, the technical solution adopted in this application is: a tray structure suitable for cleaning base stations, the tray structure including a tray, a suction nozzle and a suction nozzle sleeve, the suction nozzle being disposed on the tray and having a suction port; the suction nozzle sleeve covering the suction port, the suction nozzle sleeve having multiple water suction holes, each of the water suction holes communicating with the suction port, and the diameter of the water suction hole being smaller than the diameter of the suction port.

[0006] Optionally, the tray has a water-holding trough for holding wastewater, and the suction hole is disposed close to the bottom surface of the water-holding trough.

[0007] Optionally, the plurality of water-absorbing holes are arranged to form a water-absorbing area, and the suction nozzle sleeve is provided with a filter screen for blocking large particles of impurities from entering the water-absorbing holes, and the filter screen surrounds the water-absorbing area.

[0008] Optionally, the filter screen includes a plurality of support columns protruding from the suction nozzle sleeve, the plurality of support columns being spaced apart around the water absorption area, and the support columns abutting against the bottom surface of the water holding tank.

[0009] Optionally, the nozzle sleeve is a nozzle rubber sleeve.

[0010] Optionally, the nozzle sleeve is detachably connected to the nozzle, or the nozzle sleeve is integrally formed with the nozzle.

[0011] Optionally, the suction nozzle includes a suction tube and a fixing bracket. The suction tube has a first section and a second section that are connected to each other. The suction port is formed on the end of the first section facing away from the second section. The suction sleeve covers the first section. The second section is connected to the fixing bracket. The fixing bracket is fixed to the tray and located between the tray and the second section. The water suction hole is opened at the bottom of the suction sleeve. In the direction facing away from the second section, the first section extends downward at an angle toward the water suction hole, so that the suction port is set close to the water suction hole.

[0012] Optionally, the tray structure further includes an adapter and a connecting pipe. The side wall of the tray is provided with a through hole. The adapter is installed on the tray, and one end of the adapter passes through the through hole and is used to communicate with the sewage suction device in the cleaning base station. The other end of the adapter is connected to one end of the connecting pipe, and the other end of the connecting pipe is connected to the suction nozzle.

[0013] The tray structure provided in this application has at least one of the following technical effects: When the wastewater from cleaning accumulates in the tray, the suction port of the nozzle promptly removes the wastewater, avoiding secondary pollution and improving the cleaning effect. During this process, the wastewater first enters the nozzle sleeve through multiple suction holes and then is sucked into the suction port of the nozzle. The diameter of the suction holes is smaller than the diameter of the suction port, meaning that the wastewater enters the large-diameter suction port of the nozzle from multiple small-diameter suction holes. The small-diameter suction holes are less likely to suck in air, resulting in less suction noise and solving the problem of loud suction noise. At the same time, the suction force of the wastewater is more uniform, the suction noise is lower, and the multiple suction holes also ensure a sufficiently large suction port diameter, giving the tray structure good suction efficiency and effect. In addition, the small diameter of the suction holes can also prevent large particles of impurities from entering the nozzle, avoiding blockage.

[0014] In another embodiment of this application, a cleaning base station is provided, including a base station body and the aforementioned tray structure. The tray is disposed at the bottom of the base station body and forms a cleaning station for cleaning a cleaning robot with the base station body.

[0015] The cleaning base station in this embodiment of the application adopts the aforementioned tray structure. When the wastewater from cleaning accumulates in the tray, the suction port of the nozzle promptly removes the wastewater, avoiding secondary pollution and improving the cleaning effect. During this process, the wastewater first enters the nozzle sleeve through multiple suction holes and then is sucked into the suction port of the nozzle. The diameter of the suction holes is smaller than the diameter of the suction port, meaning that the wastewater enters the large-diameter suction port of the nozzle from multiple small-diameter suction holes. The small-diameter suction holes are less likely to suck in air, resulting in less suction noise and solving the problem of loud suction noise. At the same time, the suction force of the wastewater is more uniform, and the suction noise is lower. Furthermore, the multiple suction holes ensure a sufficiently large suction port diameter, giving the tray structure good suction efficiency and effect. In addition, the small diameter of the suction holes can also prevent large particles of impurities from entering the nozzle, avoiding blockage.

[0016] In another embodiment of this application, a cleaning device is provided, including a cleaning robot and the aforementioned cleaning base station.

[0017] The cleaning equipment of this application embodiment, by employing the aforementioned cleaning base station, allows for timely removal of wastewater from the suction port of the nozzle when it accumulates in the tray, preventing secondary pollution and improving cleaning efficiency. During this process, the wastewater first enters the nozzle sleeve through multiple suction holes before being drawn into the suction port. The diameter of the suction holes is smaller than the diameter of the suction port, meaning the wastewater enters the large-diameter suction port of the nozzle through multiple small-diameter suction holes. The small-diameter suction holes are less prone to air intake, resulting in less suction noise and solving the problem of loud suction. Simultaneously, the suction force is more uniform, and the suction noise is lower. Furthermore, the multiple suction holes ensure a sufficiently large suction port diameter, giving the tray structure excellent suction efficiency and effect. Additionally, the small diameter of the suction holes also prevents large particles of impurities from entering the nozzle, avoiding blockage. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0027] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0028] like Figures 1-4 As shown, in one embodiment of this application, a tray structure is provided, suitable for cleaning base stations and used in conjunction with a cleaning robot. The tray structure includes a tray 10, a suction nozzle 20, and a suction nozzle sleeve 30. The suction nozzle 20 is disposed on the tray 10 and has a suction port. In specific applications, the tray 10 is disposed at the bottom of the base station body and forms a cleaning station with the bottom surface of the base station body. When the cleaning components on the cleaning robot need to be cleaned, the cleaning robot enters the tray 10, that is, enters the cleaning station. The cleaning components in the cleaning station clean the cleaning components. At the same time, the wastewater flowing down from the cleaning process is collected in the tray 10 and is promptly sucked away through the suction port of the suction nozzle 20 to avoid secondary pollution and improve the cleaning effect. The suction nozzle sleeve 30 covers the suction port and has multiple suction holes 31. Each suction hole 31 is connected to the suction port, and the diameter of the suction hole 31 is smaller than the diameter of the suction port.

[0029] The tray structure of this application embodiment will be further explained below. When the wastewater from the cleaning robot's cleaning components accumulates in the tray 10, the suction port of the suction nozzle 20 promptly removes the wastewater, avoiding secondary pollution and improving the cleaning effect. In this process, the wastewater first enters the suction nozzle sleeve 30 through multiple suction holes 31, and then is sucked into the suction port of the suction nozzle 20. The diameter of the suction holes 31 is smaller than the diameter of the suction port, that is, the wastewater enters the large-diameter suction port of the suction nozzle 20 from multiple small-diameter suction holes 31. The small-diameter suction holes 31 are less likely to suck in air, resulting in less suction noise, thus solving the problem of loud suction noise. At the same time, the suction force of the wastewater is more uniform, and the suction noise is lower. Furthermore, the multiple suction holes 31 also ensure a sufficiently large suction port diameter, giving the tray structure good suction efficiency and effect. In addition, the small diameter of the suction holes 31 can also prevent large particles of impurities from entering the suction nozzle 20, avoiding blockage.

[0030] In this embodiment, the cleaning base station is equipped with a clean water tank and a wastewater tank. The cleaning solution in the clean water tank flows into the cleaning station through a pipe, wetting the cleaning components at the bottom of the cleaning robot. Then, the cleaning components in the cleaning station clean the cleaning components. A wastewater suction device is provided between the suction nozzle 20 and the wastewater tank. The wastewater flowing down from the cleaning is sucked by the wastewater suction device, so that the wastewater enters the suction nozzle 20 through the water suction hole 31 on the suction nozzle sleeve 30, and finally returns to the wastewater tank. This realizes the recycling of wastewater and the cleaning of the cleaning components. The suction device can be a water pump. The cleaning components can be cleaning nozzles, cleaning brushes, or raised structures in the cleaning station, etc. The specific structure is not limited here. In addition, the cleaning robot can be a mopping robot, a sweeping robot, a window cleaning robot, or other cleaning robots with cleaning functions. The cleaning components can be rags, brushes, roller brushes, scrapers, or other parts with cleaning functions.

[0031] In another embodiment of this application, the nozzle sleeve 30 of the tray structure is detachably connected to the nozzle 20. Specifically, the nozzle sleeve 30 can be snapped onto the nozzle 20, or the nozzle sleeve 30 can be directly sleeved onto the nozzle 20. In this way, the nozzle sleeve 30 and the nozzle 20 are easy to assemble and disassemble and are easy to clean. In addition, its structure is simple and its manufacturing cost is low.

[0032] In another embodiment of this application, the suction sleeve 30 of the tray structure is integrally formed with the suction nozzle 20, which has a simple manufacturing process, good structural strength, and low manufacturing cost.

[0033] In another embodiment of this application, combined with Figure 1 , Figure 2 and Figure 3 As shown, the tray 10 provided with this tray structure has a water-holding tank 11 for holding sewage, and the suction hole 31 is set close to the bottom surface of the water-holding tank 11. When the sewage in the tray 10 accumulates on the water-holding tank 11 of the tray 10, at this time, the suction hole 31 is close to the bottom of the sewage. In this way, the suction force of the suction hole 31 is large, the sewage suction efficiency is high, and the sewage can be completely sucked out. In addition, the suction hole 31 can be completely immersed in the sewage for suction, preventing air from being drawn into the suction hole 31 and reducing suction noise.

[0034] In this embodiment, a slope plate 12 is connected to one side of the tray 10 to facilitate the entry of the cleaning robot into the tray 10. The inner cavity of the tray 10 is directly a water tank 11, or the bottom surface of the inner cavity of the tray 10 is recessed downward to form a water tank 11. The suction nozzle sleeve 30 is located in the recess of the inner cavity of the tray 10 to facilitate the collection and suction of sewage.

[0035] In another embodiment of this application, combined with Figure 2 , Figure 3 and Figure 4As shown, the tray structure provided has multiple suction holes 31 that enclose a suction area. The suction nozzle sleeve 30 is equipped with a filter screen to prevent large particles of impurities from entering the suction holes 31. The filter screen surrounds the suction area. Under the suction action of the suction holes 31, sewage enters the suction holes 31 after being filtered by the filter screen around the suction area. When the sewage passes through the filter screen, large particles in the sewage are blocked and cannot pass through the filter screen, thereby achieving the sewage filtration effect and preventing large particles of impurities from clogging the suction holes 31 and the suction nozzle 20.

[0036] In another embodiment of this application, combined with Figure 2 , Figure 3 and Figure 4 As shown, the provided tray structure filter screen includes multiple support columns 32 protruding from the suction nozzle sleeve 30. The multiple support columns 32 are spaced around the water absorption area, and the support columns 32 abut against the bottom surface of the water tank 11. The filter screen is composed of multiple spaced support columns 32, and its structure is simple and easy to manufacture. Under the suction action of the water absorption hole 31, sewage flows into the water absorption hole 31 through the gaps between the support columns 32 around the water absorption area, and finally returns to the sewage tank through the suction nozzle 20. In this way, sewage recycling is achieved. When the sewage passes through the gaps between the support columns 32, large particles in the sewage are blocked and cannot pass through the gaps, thereby achieving the sewage filtration effect and preventing large particles of impurities from clogging the water absorption hole 31 and the suction nozzle 20. It should be noted that the spacing between the support columns 32 can be designed according to the shape and size of impurities in the sewage, the diameter of the suction hole 31, the diameter of the suction port, the usage requirements of the sewage suction device, and the pipe size, as long as the sewage suction is smooth and there is no blockage problem. No specific limit is made here.

[0037] In this embodiment, the number of water absorption holes 31 can be three, four, five or more. The specific number and the diameter of the water absorption holes 31 can be set according to actual needs and are not limited here.

[0038] In a specific embodiment, combined with Figure 2 As shown, there are nine suction holes 31. Three suction holes 31 are distributed along the length of the nozzle sleeve 30, and the other six suction holes 31 are evenly distributed around the three front suction holes 31. Based on this structure, the suction holes 31 are evenly distributed, resulting in gentler and more uniform water absorption, effectively reducing suction noise. Furthermore, the nozzle sleeve 30 can be in the form of a cuboid, cylinder, ellipse, or other structural shapes, which are not limited here. For example, combined with... Figure 2 As shown, the nozzle sleeve 30 is a cuboid, with nine water-absorbing holes 31 located in the middle of the bottom surface of the nozzle sleeve 30. The nine water-absorbing holes 31 form a water-absorbing area. The support columns 32 are distributed in a rectangular pattern along the circumference of the cuboid. Its structure is regular and easy to manufacture.

[0039] In another embodiment of this application, the nozzle sleeve 30 of the tray structure provided is a nozzle rubber sleeve. The nozzle sleeve 30 is made of rubber material. On the one hand, its manufacturing process is simple, and rubber material is not prone to bacterial growth, is easy to clean, and is not easily damaged by water immersion, ensuring hygiene and avoiding secondary pollution, and ensuring reliability in use; on the other hand, the nozzle rubber sleeve is easy to deform, which also facilitates the disassembly and assembly of the nozzle sleeve 30 and the nozzle 20.

[0040] In another embodiment of this application, combined with Figure 2 and Figure 3 As shown, the provided tray structure suction nozzle 20 includes a suction tube 21 and a fixing bracket 22. The suction tube 21 has a first section 211 and a second section 212 that are connected. The suction port is formed on the end of the first section 211 facing away from the second section 212. The suction sleeve 30 covers the first section 211. The second section 212 is connected to the fixing bracket 22. The fixing bracket 22 is fixed to the tray 10 and is located between the tray 10 and the second section 212. The suction hole 31 is opened at the bottom of the suction sleeve 30. In the direction facing away from the second section 212, the first section 211 extends downward at an angle toward the suction hole 31 so that the suction port is close to the suction hole 31. Based on this structure, the suction port at the end of the first section 211 is positioned as close as possible to the water suction hole 31. On the one hand, the sewage suction force is strong and the sewage suction effect is good. On the other hand, sewage entering the water suction hole 31 can quickly enter the suction port, preventing air from being sucked into the suction port and causing loud water suction noise. At the same time, the fixing bracket 22 fixes the nozzle 20 and lifts the second section 212 to prevent impurities in the sewage from accumulating at the connection between the tray 10 and the second section 212, making cleaning easier.

[0041] In this embodiment, the suction hole 31 is set close to the bottom surface of the water tank 11, so that when there is less sewage, the suction hole 31 and the suction port are still completely immersed in the sewage, thereby preventing air from entering the suction hole 31 and reducing suction noise. In a specific embodiment, combined with Figure 2 and Figure 3 As shown, the fixed bracket 22 includes a connecting plate 221 and fixed sleeves 222 disposed at both ends of the connecting plate 221. The two fixed sleeves 222 are connected to the outer wall of the suction tube 21 and are located on opposite sides of the suction tube 21. The water tank 11 of the tray 10 is provided with two spaced fixed posts 14. The two fixed sleeves 222 are respectively sleeved on the fixed posts 14 and fixed on the fixed posts 14 by fasteners. The connecting plate 221 is located between the second section of the suction tube 21 and the water tank 11. The fixed bracket 22 can be integrally formed with the suction tube 21. Its manufacturing process is simple and the manufacturing cost is low.

[0042] In another embodiment of this application, combined with Figure 2 and Figure 3 As shown, the provided tray structure also includes an adapter 40 and a connecting pipe 50. A through hole 13 is provided on the side wall of the tray 10. The adapter 40 is installed on the tray 10, with one end of the adapter 40 passing through the through hole 13 and used to communicate with the sewage suction device inside the cleaning base station. The other end of the adapter 40 is connected to one end of the connecting pipe 50, and the other end of the connecting pipe 50 is connected to the suction nozzle 20. The suction nozzle 20 located in the middle of the tray 10 can be connected to the sewage suction device inside the cleaning base station through the connecting pipe 50 and the adapter 40. Its structure is simple, easy to manufacture, and has low processing costs. Furthermore, it should be noted that the adapter 40 can be easily disassembled and reassembled with the sewage suction device inside the cleaning base station, facilitating manufacturing.

[0043] In a specific embodiment, combined with Figure 2 and Figure 3 As shown, the adapter 40 includes an adapter pipe 41 and connecting sleeves 42 disposed on both sides of the adapter pipe 41. The water tank 11 of the tray 10 is provided with two spaced connecting posts 15. The connecting pipe 50 is connected to the second section 212 of the suction pipe 21. The adapter pipe 41 connects the connecting pipe 50 and the sewage suction device. The two connecting sleeves 42 are fitted on the connecting posts 15 and finally fixed by fasteners. Its fixed connection has good reliability, and its structure is simple, convenient to process and manufacture, and reduces costs.

[0044] In this embodiment, the fastener may be a screw, bolt, or bolt.

[0045] In another embodiment of this application, the connecting tube 50 of the tray structure is a silicone tube. The nozzle sleeve 30 is made of silicone material. On the one hand, its manufacturing process is simple, and silicone material is not prone to bacterial growth, is easy to clean, and is not easily damaged by water immersion, ensuring hygiene and avoiding secondary pollution, thus ensuring reliable use. On the other hand, silicone tubes are easy to deform, which also facilitates the assembly and disassembly of the connecting tube 50.

[0046] In another embodiment of this application, a cleaning base station is provided, including a base station body and the aforementioned tray structure. The tray 10 is disposed at the bottom of the base station body and forms a cleaning station for cleaning a cleaning robot around the base station body.

[0047] The cleaning base station of this application embodiment, due to the adoption of the above-mentioned tray structure, allows the wastewater from the cleaning robot's cleaning components to accumulate in the tray 10. The suction port of the nozzle 20 promptly removes the wastewater, preventing secondary pollution and improving the cleaning effect. During this process, the wastewater first enters the nozzle sleeve 30 through multiple suction holes 31 and then is sucked into the suction port of the nozzle 20. The diameter of the suction holes 31 is smaller than the diameter of the suction port, meaning that the wastewater enters the large-diameter suction port of the nozzle 20 through multiple small-diameter suction holes 31. The small-diameter suction holes 31 are less likely to suck in air, resulting in less suction noise and solving the problem of loud suction noise. At the same time, the suction force of the wastewater is more uniform, and the suction noise is lower. Furthermore, the multiple suction holes 31 ensure a sufficiently large suction port diameter, giving the tray structure good suction efficiency and effect. In addition, the small diameter of the suction holes 31 also prevents large particles of impurities from entering the nozzle 20, avoiding blockage. The cleaning base station in this application adopts the tray structure of all the above embodiments, and the cleaning base station also has the beneficial effects of all the above embodiments, which will not be repeated here.

[0048] In another embodiment of this application, a cleaning device is provided, including a cleaning robot and the aforementioned cleaning base station.

[0049] The cleaning equipment of this embodiment, by employing the aforementioned cleaning base station, allows for timely removal of wastewater from the cleaning robot's cleaning components when it accumulates in the tray 10. This prevents secondary pollution and improves cleaning efficiency. During this process, the wastewater first enters the nozzle sleeve 30 through multiple suction holes 31 before being drawn into the suction port of the nozzle 20. The diameter of the suction holes 31 is smaller than the diameter of the suction port, meaning the wastewater enters the large-diameter suction port of the nozzle 20 through multiple small-diameter suction holes 31. The small-diameter suction holes 31 are less prone to air intake, resulting in less suction noise and solving the problem of loud suction. Simultaneously, the suction force is more uniform, and the suction noise is lower. Furthermore, the multiple suction holes 31 ensure a sufficiently large suction port diameter, giving the tray structure good suction efficiency and effect. Additionally, the small diameter of the suction holes 31 also prevents large particles of impurities from entering the nozzle 20, avoiding blockage. The cleaning device in this application uses the cleaning base station of all the above embodiments, and the cleaning device also has the beneficial effects of all the above embodiments, which will not be repeated here.
