[0002] Cleaning robots, such as robotic vacuum cleaners, can be equipped with base stations that control the cleaning cloths or rollers of the cleaning equipment. During the cleaning process, the wastewater generated contains a large amount of particulate matter. Because these particulate matter tends to settle in the tray, it cannot be properly drained, leading to an accumulation of impurities in the water tank. Utility Model Content

It should be understood that those skilled in the art will recognize that this application can be made without using these specific details.

Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0033] Cleaning robots can clean surfaces; for example, a robotic vacuum cleaner can be used to clean floors. During the cleaning process, particulate matter and impurities may accumulate on the robot's rollers or cloth. When equipped with a cleaning base station, the robot can dock on it, aligning its rollers or cloth with the base station's tray. The base station then cleans the rollers or cloth. The tray at the bottom of the base station provides space to hold the rollers or cloth, and wastewater generated during cleaning can be collected within it.

[0034] After cleaning the roller or cloth, when draining the wastewater from the tray, the particulate impurities are relatively heavy and tend to settle at the bottom of the tray, making it difficult for them to flow out with the wastewater. This leads to the accumulation of impurities and the growth of bacteria in the tray.

[0035] This application addresses the problem of particulate impurities easily accumulating in a tray by proposing a tray comprising a tray body and an air inlet assembly disposed on the tray body. The tray body is at least partially recessed to form a washing tank. The tray body has a drain outlet and an air inlet connected to the washing tank. One end of the air inlet assembly is connected to the air inlet, and the other end is used to connect to an air source. The air inlet assembly is used to connect to the air source to inject gas into the water when there is water in the washing tank. In this example, the connected air source can generate a surge in the washing tank, thereby agitating the particulate impurities at the bottom of the washing tank and reducing the possibility of particulate impurities accumulating at the bottom of the washing tank.

[0036] Please see Figure 1 In this application example, the tray 10 can be used for the cleaning base station 100, which can be used to dock cleaning robots such as sweeping robots. When the sweeping robot docks on the cleaning base station 100, the sweeping robot's roller can be partially contained in the water washing tank 111 of the tray 10. Clean water or a mixture of clean water and cleaning liquid is introduced into the water washing tank 111 to clean the roller. After the roller is cleaned, an air source can be connected through the air intake component 12 so that a surge can be formed in the water washing tank 111 during the sewage discharge process, reducing the deposition of particulate impurities at the bottom of the water washing tank 111.

[0037] The tray 10 in this application example can be used for cleaning equipment, which may include a cleaning base station 100 and a cleaning robot. The cleaning robot may be a sweeping robot, a mopping robot, a sweeping and mopping robot, or other devices that can be used to clean the surface to be cleaned.

[0038] Please see Figure 2 , Figure 3 and Figure 4This application proposes an example of a tray 10 for cleaning a base station 100. The tray 10 includes a tray body 11 and an air intake assembly 12. A water washing tank 111 is formed on the tray body 11. A drain outlet 112 and an air inlet 113 communicating with the water washing tank 111 are provided on the tray body 11. The air intake assembly 12 is disposed on the tray body 11 and communicates with the air inlet 113 for injecting gas into the water through the air inlet 113 when there is water in the water washing tank 111.

[0039] The disc body 11 can serve as the main structure of the tray 10, and can be fixedly or detachably connected to the base station body 20 of the cleaning base station 100. A water washing tank 111 is formed on the disc body 11, including at least a portion of the upper surface or side of the disc body 11 recessed inward to form a space for accommodating a roller or a wiping cloth. Alternatively, an intermediate connector with a recessed groove can be provided on the disc body 11, forming a space for accommodating a roller or a wiping cloth on the disc body 11 through the intermediate connector. In this example, the position and size of the water washing tank 111 can be adapted to the cleaning robot that is compatible with the cleaning base station 100. Taking a sweeping robot with rollers as an example, the water washing tank 111 can be a recessed groove formed by the downward inward recess of the upper surface of the disc body 11. The size of the water washing tank 111 can be slightly larger than the size of the roller. When the sweeping robot is parked on the cleaning base station 100, the roller of the sweeping robot can be suspended in the water washing tank 111. When clean water or a mixture of cleaning solution and clean water (hereinafter referred to as cleaning solution) is introduced into the washing tank 111, the roller is cleaned by the cleaning solution.

[0040] Please refer to the following: Figure 5 The disc body 11 has a drain outlet 112 that connects to the washing tank 111. The drain outlet 112 can be a through hole that penetrates the bottom wall or side wall of the disc body 11, and can be used to discharge sewage from the washing tank 111. In this example, the drain outlet 112 can be located at the lowest point of the washing tank 111 so that sewage can flow towards the drain outlet 112. In some examples, a water suction pipe 115 can be provided on the disc body 11. The water suction pipe 115 can be used to connect a negative pressure device such as a water pump 22, so that a negative pressure is formed at the drain outlet 112 through the negative pressure device, thereby accelerating the discharge of sewage.

[0041] The disc body 11 has an air inlet 113 that connects to the water washing tank 111. The air inlet 113 can be a through hole that penetrates the bottom wall or side wall of the disc body 11.

[0042] The air intake assembly 12 is located on the disc body 11, meaning that the air intake assembly 12 can be directly or indirectly connected to a preset position on the disc body 11. One end of the air intake assembly 12 is connected to the air inlet 113, and the other end can be used to connect to an air source. The air source refers to a device outside the washing tank 111 that can output airflow to the air intake assembly 12. In this example, the air intake assembly 12 is connected to the outside of the disc body 11 through the air source assembly 14. The airflow from the air source can be delivered to the air inlet 113 via the air intake assembly 12. The gas input into the air inlet 113 can enter the washing tank 111. By injecting gas into the washing tank 111, the water in the washing tank 111 is agitated. As the gas disturbs the flow of sewage in the washing tank 111, particulate impurities in the sewage are less likely to adhere to the bottom wall of the washing tank 111. This makes it easier for particulate impurities in the sewage to flow towards the drain outlet 112, reducing the deposition of particulate matter in the washing tank 111. In this example, the air intake assembly 12 can partially pass through the air intake port 113 and extend into the water washing tank 111. The air intake assembly 12 can also be connected to the outer wall of the disc body 11 and communicate with the air intake port 113.

[0043] In this example, when there is water in the washing tank 111, an air source is connected through the air intake assembly 12 to inject gas into the water in the washing tank 111. During the gas injection process, the gas can cause the water in the washing tank 111 to surge or eddy, thereby agitating the particles at the bottom of the washing tank 111, making it easier for the particles to flow towards the drain outlet 112 along with the sewage. Optionally, in this example, the water in the washing tank 111 can be cleaning fluid injected into the washing tank 111 when the washing tank 111 is empty or nearly empty. Specifically, in this example, after the cleaning of the roller is completed, the sewage in the washing tank 111 can be drained first, and then cleaning fluid for cleaning the washing tank 111 can be introduced into the washing tank 111. Then, an air source is connected through the air intake assembly 12 to agitate the cleaning fluid in the washing tank 111. The agitated cleaning fluid cleans the washing tank 111 and reduces the adhesion of particulate impurities to the inner wall of the washing tank 111.

[0044] Optionally, the water in the washing tank 111 in this example can be wastewater generated after cleaning the roller; specifically, in this example, after cleaning the roller, while discharging the wastewater, an air source can be connected through the air intake component 12 to agitate the wastewater so that particulate impurities in the wastewater do not easily adhere to the inner wall surface of the washing tank 111.

[0045] Optionally, the water in the washing tank 111 in this example can be the cleaning fluid that enters the washing tank 111 during the cleaning of the roller. Specifically, in this example, when cleaning the roller, an air source can be connected through the air intake component 12 to agitate the cleaning fluid used to clean the roller, so as to reduce the adhesion of particulate matter on the inner wall surface of the washing tank 111. When the sewage in the washing tank 111 is discharged, the particulate impurities can flow with the sewage to the drain outlet 112.

[0046] In some examples, the timing of the air intake assembly 12 injecting cleaning fluid into the washing tank 111 can be determined based on the water level in the washing tank 111. When the water level in the washing tank 111 is too low, the agitation effect of the gas injected by the air intake assembly 12 may be relatively low. Therefore, in this application, the cleaning fluid can be injected into the washing tank 111 only when the water level in the washing tank 111 reaches a preset range, based on parameters such as the shape and depth of the washing tank 111. The preset water level can mean that the air intake assembly 12 injects gas into the washing tank 111 when the water level itself in the washing tank 111 reaches a preset height. Optionally, when the water level in the washing tank 111 does not reach the preset height, cleaning fluid or clean water can be injected into the washing tank 111 first to bring the water level in the washing tank 111 to the preset height before the air intake assembly 12 injects gas into the washing tank 111. Optionally, when the water in the washing tank 111 has been drained, cleaning fluid can be injected into the washing tank 111 first. When the water level of the cleaning fluid reaches a preset height, gas is then injected into the washing tank through the air intake component 12. In this example, the gas injected by the air intake component 12 is used to agitate the liquid flow in the washing tank 111, and the preset water level can be selected according to the specific shape of the washing tank 111.

[0047] In this example, the position of the air inlet 113 and the flow rate and velocity of the gas input into the air inlet 113 can be determined based on parameters such as the depth of the washing tank 111 and the position of the drain outlet 112. This ensures that the airflow injected into the washing tank 111 can agitate the water inside the washing tank 111 without causing water to splash out. Optionally, in this example, the air inlet 113 can be positioned towards the bottom of the washing tank 111, so that the air inlet 113 injects gas towards the bottom of the washing tank 111. On the one hand, the gas directly acts on the particulate impurities near the inside of the washing tank 111. On the other hand, it can generate a surge in the washing tank 111, prolonging the time that the water flow acts on the particulate matter, making it easier for the particulate matter to be discharged from the drain outlet 112 along with the sewage.

[0048] In some examples, there can be multiple air inlets 113. By adjusting the angle and number of air inlets 113, the airflow injected from the air inlets 113 can form a vortex in the washing tank 111, thereby reducing the deposition of particulate matter at the bottom of the washing tank 111.

[0049] In some examples, the air inlet 113 and the drain outlet 112 are located on opposite sides of the disc 11. In this example, the air inlet 113 can act directly on the water on the side opposite to the drain outlet 112, causing particulate impurities to tend to move towards the drain outlet 112, increasing the likelihood that particulate impurities will be discharged from the drain outlet 112 along with the sewage.

[0050] In some examples, the washing tank 111 has a length direction, and the drain outlet 112 extends along the length direction of the washing tank 111. In this example, by making the length direction of the drain outlet 112 extend along the length direction of the washing tank 111, the coverage area of ​​the drain outlet 112 can be extended, increasing the possibility that particulate matter inside the washing tank 111 can be discharged from the drain outlet 112.

[0051] In some examples, the air inlet 113 is positioned towards the drain outlet 112. In this example, the air inlet 113 can be used to inject gas directly towards the drain outlet 112, pushing particulate matter towards the drain outlet 112 and thus increasing the likelihood of particulate matter exiting from the drain outlet 112. The air inlet 113 being positioned towards the drain outlet 112 in this example includes the air inlet 113 being directly opposite the drain outlet 112, or the air inlet 113 being inclined at an angle to the drain outlet 112, so that the air inlet 113 pushes particulate impurities near the drain outlet 112 towards the drain outlet 112. In this example, the likelihood of particulate impurities flowing towards the drain outlet 112 can be increased by using combinations of air inlets 113 with different positions and / or different angles.

[0052] In some examples, the air inlet 113 is elongated and extends along the length of the drain outlet 112. In this example, at least one elongated air inlet 113 can be used to extend the effective area of ​​the air inlet 113, generate a larger range of surges in the washing tank 111, and thus reduce the possibility of particulate matter depositing at the bottom of the washing tank 111.

[0053] In some examples, there are multiple air inlets 113, which are spaced apart along the length of the drain outlet 112. In this example, by setting multiple air inlets 113, airflow injection points can be formed at multiple locations within the washing tank 111, increasing the effective area of ​​the airflow. Multiple air inlets 113 facilitate water agitation within the washing tank 111. The interaction of airflows injected from different inlets 113 increases the complexity of water flow disturbance within the washing tank 111, allowing more particulate impurities to float with the water flow and preventing them from depositing on the bottom wall of the washing tank 111. In this example, the multiple air inlets 113 are spaced apart along the length of the drain outlet 112, ensuring that all inlets 113 can act on the area near the drain outlet 112, increasing the likelihood of particulate impurities being discharged from the drain outlet 112.

[0054] In some examples, there are multiple air inlets 113, with at least some air inlets 113 positioned opposite to drain outlets 112. Taking the width direction of the disc body 11 as an example, the drain outlet 112 can be located on one side of the disc body 11 along its width direction, and all air inlets 113 can be located on the other side of the disc body 11 along its width direction; alternatively, the drain outlet 112 can be located on one side of the disc body 11 along its width direction, some air inlets 113 can be located on the same side as the drain outlet 112, and some air inlets 113 can be located on the other side of the disc body 11 along its width direction. In this application, by injecting gas into the washing tank 111 through the air inlet 113 located on the opposite side of the drain outlet 112, the particles in the washing tank 111 can be subjected to a pushing force towards the drain outlet 112, thereby accelerating the output of the particles from the drain outlet 112. When the air inlet 113 is located on the same side as the drain outlet 112, the airflow injected through the air inlet 113 located on the same side of the drain outlet 112 can generate vortices in the washing tank 111, thereby increasing the area of ​​the airflow acting on the water flow.

[0055] In some examples, the washing tank 111 has a length direction, wherein the drain outlet 112 is centrally located along the length direction of the washing tank 111, so that the sewage and impurities on both sides of the drain outlet 112 can flow more evenly towards the drain outlet 112, reducing the problem of uneven distribution of water and impurities in the washing tank 111 caused by the offset of the position of the drain outlet 112 relative to the midpoint of the length direction of the washing tank 111, and helping to improve cleaning efficiency.

[0056] In some examples, the washing tank 111 has a length direction, wherein the air inlet 113 is centrally located in the length direction of the washing tank 111, so that the gas input through the air inlet 113 can form a surge in the middle of the washing tank 111, accelerate the water flow in the washing tank 111, and reduce the problem of impurities accumulating in some parts of the washing tank 111 due to the offset of the air injection position.

[0057] In some examples, the washing tank 111 has a length direction, wherein the drain outlet 112 is centrally located along the length direction of the washing tank 111, and the air inlet 113 is centrally located along the length direction of the washing tank 111. In this example, the gas injected into the air inlet 113 can directly impact the drain outlet 112, thereby reducing the accumulation of impurities at the drain outlet 112 of the washing tank 111 and helping to accelerate the flow of impurities from the drain outlet 112.

[0058] In some examples, the drain outlet 112 is elongated and extends along the length of the washing tank 111, so that the drain outlet 112 can cover a larger area along the length of the washing tank 111, and impurities in the washing tank 111 can flow out through the drain outlet 112 nearby, thereby increasing the possibility of sewage and impurities being discharged from the drain outlet 112.

[0059] In some examples, the tray 10 also includes a water level detection component 15, which detects the water level in the washing tank 111 and injects gas into the tray 10 when the water level reaches a preset depth. Optionally, in this example, the water level in the washing tank 111 can be detected during drainage after the rollers have been cleaned. When the water level reaches the preset level, gas is then injected into the washing tank 111 through the air intake component 12. By determining the water level before injecting gas, the problem of wastewater splashing during agitation due to excessively high water levels in the washing tank 111 can be reduced. Optionally, in this example, cleaning fluid can be injected into the washing tank 111 after it is empty or nearly empty. The water level detection component 15 detects the water level of the injected cleaning fluid, and gas is then injected through the air source component 14 when the water level reaches the preset level.

[0060] In some examples, the tray 10 also includes an air supply assembly 14, which is connected to the air intake assembly 12 and is used to supply gas to the air intake assembly 12. In this example, the air supply assembly 14 can be used to pressurize and draw airflow from outside the tray 10 to the air intake assembly 12. The air supply assembly 14 can be directly connected to the tray body 11, or it can be indirectly connected to the tray body 11 via an intermediate connector. Optionally, the air supply assembly 14 includes at least one of an air pump and a fan.

[0061] In some examples, tray 10 also includes a water level detection component 15 and an air source component 14. The water level detection component 15 is mounted on tray body 11 and is used to detect the water level signal in the washing tank 111. The air source component 14 is connected to air intake component 12 and is electrically connected to the water level detection component 15. The air source component 14 is used to pump gas to air intake component 12 according to the water level signal. The electrical connection between air source component 14 and water level detection component 15 means that air source component 14 can receive the electrical signal from water level detection component 15. In this example, the controller can receive the electrical signal from water level detection component 15 and control the operation of air source component 14. The controller can be an integrated controller integrated on water pump 22, or it can be an integrated module integrated on tray 10 or cleaning base station 100. In this example, air source component 14 can be used to pressurize and pump airflow from outside tray 10 to air intake component 12. Air source component 14 can be directly connected to tray body 11, or it can be indirectly connected to tray body 11 through an intermediate connector. The water level detection component 15 is used to detect the water level in the washing tank 111 so that gas is injected into the tray 10 when the water level in the tray 10 reaches a certain depth. Optionally, in this example, the water level in the washing tank 111 can be detected when draining after the rollers have been cleaned. When the water level reaches a preset level, the air source component 14 is then activated to inject gas into the washing tank 111. By determining the water level before injecting gas, the problem of wastewater splashing during agitation due to excessively high water levels in the washing tank 111 can be reduced. Optionally, in this example, cleaning fluid can be injected into the washing tank 111 after it is empty or nearly empty. The water level detection component 15 detects the water level of the injected cleaning fluid, and gas is injected through the air source component 14 when the water level reaches a preset level.

[0062] In some examples, there are multiple air inlets 113, and the air intake assembly 12 may include multiple branch pipes 122 that are respectively connected to the air source assembly 14. Alternatively, the air intake assembly 12 may include a plurality of branch pipes 122 and at least one main pipe 121, wherein the plurality of branch pipes 122 are respectively connected to the plurality of air inlets 113, and the main pipe 121 is connected between the plurality of branch pipes 122 and the air source assembly 14.

[0063] In some examples, the tray body 11 is also provided with a water inlet 114 that connects to the water washing tank 111. The tray 10 also includes a water inlet component 13, which is disposed on the tray body 11. One end of the water inlet component 13 is connected to the water inlet 114. The water inlet component 13 is used to spray water into the water washing tank 111 through the water inlet 114.

[0064] The water inlet 114 can be a through hole provided on the disc body 11. The water inlet 114 is used to connect to the water inlet assembly 13 so that the cleaning fluid input by the water inlet assembly 13 can enter the water washing tank 111. In this example, the water inlet assembly 13 can pass through the water inlet 114 and extend into the water washing tank 111, or the water inlet assembly 13 can be connected to the outer wall surface of the disc body 11 and communicate with the water inlet 114.

[0065] The external water source can be a water tank 21 installed on the panel 11 or the cleaning base station 100, or other water sources. The water inlet assembly 13 is used to connect to the external water source so that the external water source can enter the washing tank 111 through the water inlet assembly 13 and the water inlet 114.

[0066] In this example, by setting an inlet 114 and an inlet component 13 that can be connected to an external water source, cleaning fluid can be injected into the washing tank 111 when needed to clean the washing tank 111. When the cleaning fluid in the washing tank 111 reaches a preset water level, gas can be injected into the cleaning fluid in the washing tank 111 through the air inlet 113 to agitate the cleaning fluid, making it difficult for particulate impurities to settle in the washing tank 111. When the cleaning fluid is discharged from the drain outlet 112, more particulate impurities can be discharged from the drain outlet 112 along with the cleaning fluid.

[0067] In some examples, the washing tank 111 has a length direction, and at least one end of the washing tank 111 along the length direction is provided with a water inlet 114. In this example, by injecting cleaning liquid into at least one end of the washing tank 111 along the length direction of the water inlet 114, the effective area of ​​the cleaning liquid in the washing tank 111 is increased, and particulate impurities on the bottom wall of the washing tank 111 are flushed toward the drain outlet 112.

[0068] In some examples, the washing tank 111 has a first end 116 and a second end 117 disposed opposite each other along its length, and a drain outlet 112 is located between the first end 116 and the second end 117, so that impurities can collect in the area between the first end 116 and the second end 117 of the washing tank 111. Optionally, water inlets 114 are respectively provided at both ends of the washing tank 111 along its length, and the drain outlet 112 can be located between the water inlets 114 at both ends of the washing tank 111 along its length, so that the water inlets 114 at both ends of the washing tank 111 can be used to inject cleaning fluid, and the particulate impurities are flushed toward the drain outlet 112.

[0069] In some examples, the washing tank 111 has a first end 116 and a second end 117 arranged opposite each other along its length. Both the first end 116 and the second end 117 of the washing tank 111 are provided with inlets 114 to allow cleaning fluid to be introduced from both ends along the length of the washing tank 111. The cleaning fluid introduced from both sides rinses the inner wall surface and corner areas of the washing tank 111, reducing the adhesion of impurities to the inner wall surface of the washing tank 111. Since cleaning fluid can be introduced from both sides along the length of the washing tank 111, the coverage area of ​​the cleaning fluid can be increased, reducing the problem of impurities accumulating at the other end due to the cleaning fluid being injected only at one end of the washing tank 111.

[0070] In some examples, the washing tank 111 has a first end 116 and a second end 117 arranged opposite each other along the length direction. Both the first end 116 and the second end 117 of the washing tank 111 are provided with water inlets 114, and the drain outlet 112 is centrally located along the length direction of the washing tank 111. This allows the water inlets 114 located at the first end 116 and the second end 117 to flush impurities at both ends of the washing tank 111 toward the middle of the washing tank 111, thereby reducing the accumulation of impurities at the edges and corners of the washing tank 111.

[0071] In some examples, the inlet 114 is located on the side wall of the washing tank 111 so that the cleaning liquid sprayed from the inlet 114 can act on the bottom surface of the washing tank 111. This improves the cleaning efficiency and accelerates the flow of the cleaning liquid on the bottom surface of the washing tank 111, thereby accelerating the formation of waves in the washing liquid and further reducing the adhesion of particulate impurities at the bottom of the washing tank 111.

[0072] Please see Figure 2 , Figure 6 as well as Figure 7 In some examples, the tray 10 also includes a nozzle 16 connected to the inlet 114. The nozzle 16 includes a nozzle portion 168 and a limiting portion 162 located downstream of the nozzle portion 168. The limiting portion 162 is used to limit the angle of the water flow ejected from the nozzle portion 168.

[0073] The nozzle 16 is connected to the water inlet 114. The nozzle part 168 can be the main structure of the nozzle 16. The nozzle part 168 is provided with a water inlet channel 161 that communicates with the water inlet assembly 13. The nozzle 16 has a limiting part 162 facing the water washing tank 111, and the limiting part 162 communicates with the water inlet channel 13.

[0074] The nozzle 168 can be connected to the output end of the water inlet assembly 13. In this example, the limiting part 162 can be inserted into the water inlet 114, and the cleaning liquid is sprayed into the washing tank 111 through the limiting part 162. The limiting part 162 has a water outlet surface 165, wherein the water outlet surface 165 of the limiting part 162 is arranged facing the washing tank 111. In this example, the limiting part 162 can be arranged to be inclined downward relative to the bottom surface of the washing tank 111, or the limiting part 162 can be arranged perpendicular to the horizontal plane.

[0075] A water inlet channel 161 is provided inside the nozzle section 168, and the water inlet channel 161 is connected to the water inlet assembly 13 so that the cleaning fluid in the water inlet assembly 13 can enter the water inlet channel 161. A limiting part 162 is provided on the nozzle 16, and the limiting part 162 is connected to the water inlet channel 161 so that the cleaning fluid in the water inlet channel 161 can be output to the water washing tank 111 through the limiting part 162.

[0076] In this example, by providing the nozzle section 168, the flow rate and velocity of the cleaning fluid input into the washing tank 111 can be easily controlled. The limiting section 162 can be used to control the flow direction of the cleaning fluid output from the nozzle section 168. Taking the limiting section 162 forming a regular circular cross-section water outlet channel as an example, by adjusting the angle of the water outlet channel of the limiting section 162, the output direction of the cleaning fluid from the nozzle 16 can be adjusted, thereby enabling directional rinsing of specific parts within the washing tank 111.

[0077] In some examples, the limiting part 162 is disposed adjacent to the nozzle part 168; wherein, in the horizontal direction, the width of the limiting part 162 is greater than the width of the nozzle part 168; when the cleaning fluid enters the limiting part 162 from the nozzle part 168, since the width of the nozzle part 168 is relatively smaller than the width of the limiting part 162, the cleaning fluid can be pressurized before entering the limiting part 162, accelerating the output of the cleaning fluid from the nozzle part 168, so that the cleaning fluid forms a jet state. By increasing the spray speed of the cleaning fluid, the scouring force of the cleaning fluid on the inner wall surface of the washing tank 111 can be increased, thereby reducing the adhesion of impurities on the inner wall surface of the washing tank 111. As the spray speed of the cleaning fluid increases, the cleaning fluid can form a vortex in the washing tank 111, accelerating the flow of impurities in the washing tank 111, making it less likely for impurities to accumulate on the inner wall surface or corner areas of the washing tank 111, thereby improving the impurity discharge efficiency. Optionally, nozzles 16 are provided at both ends of the water washing tank 111 along its length. By accelerating the output of cleaning liquid from both sides, the corner areas at both ends of the water washing tank 111 along its length can be quickly rinsed by the relatively flowing cleaning liquid.

[0078] In some examples, the limiting part 162 includes an upper end face 163 and a lower end face 164, both of which are planar. In this example, both the upper end face 163 and the lower end face 164 of the limiting part can restrict the flow direction of the cleaning fluid. By using planar surfaces, the cleaning fluid can be concentrated and sprayed into a preset position in the washing tank 111 along the channel formed by the upper end face 163 and the lower end face 164 of the limiting part. This reduces the problem of cleaning fluid splashing out of the washing tank 111 and increases the scouring force of the cleaning fluid on the inner wall of the washing tank 111 by reducing cleaning fluid waste.

[0079] In some examples, the limiting part 162 is elongated, and the angle between the length direction of the limiting part 162 and the horizontal plane is no greater than 90°. In this example, by setting the limiting part 162 to be elongated, after the cleaning fluid enters the limiting part 162 from the water inlet channel 161, it can form a fan-shaped output state along the length direction of the limiting part 162, thereby increasing the coverage area when the cleaning fluid is output. The angle between the length direction of the limiting part 162 and the horizontal plane is no greater than 90°, so that the limiting part 162 is parallel to the horizontal plane or inclined relative to the horizontal plane, thereby increasing the coverage area of ​​the limiting part 162 along the horizontal direction, so that the cleaning fluid sprayed by the nozzle 16 can cover more of the inner wall surface of the washing tank 111.

[0080] In some examples, the limiting portion 162 has an inlet end 166 for connecting to the water inlet channel 161 and an outlet end 167 facing the washing tank 111, with the outlet end 167 of the limiting portion 162 inclined downward. The limiting portion 162 has an upper end surface 163 and a lower end surface 164 that are disposed opposite to each other, with the upper end surface 163 located above the lower end surface 164; the extension line of the upper end surface 163 from the inlet end 166 to the outlet end 167 can extend to the bottom surface of the washing tank 111. The upper end surface 163 and the lower end surface 164 of the limiting portion 162 are disposed opposite to each other, forming a channel for the flow of cleaning fluid between the upper end surface 163 and the lower end surface 164. The inlet end 166 of the limiting part 162 is connected to the water inlet channel 161. The inlet end 166 of the limiting part 162 is away from the water inlet channel 161 and is located on the water outlet surface 165. The extension line of the upper end surface 163 of the limiting part from the inlet end 166 to the outlet end 167 can extend downward to the bottom surface of the washing tank 111, so that the water output from the nozzle 16 can tend to spray towards the bottom surface of the washing tank 111. In this example, the angle of the water outlet surface 165 relative to the horizontal plane can be not adjusted. The water outlet direction of the nozzle 16 is limited by the angle of the upper end surface 163 and the lower end surface 164 of the limiting part, so that the cleaning liquid sprayed by the nozzle 16 can be concentrated towards the bottom surface of the washing tank 111. On the one hand, it can improve the cleaning effect of the cleaning liquid, and on the other hand, it can reduce the splashing of the cleaning liquid outside the washing tank 111.

[0081] In some examples, the central axis of the limiting part 162 is inclined downwards, and the central axis of the limiting part 162 refers to the line connecting the geometric centers of the inlet end 166 and the outlet end 167 of the limiting part 162. In this example, by making the central axis of the limiting part 162 inclined downwards, the cleaning fluid output by the limiting part 162 can be concentrated and sprayed towards the inner wall surface of the washing tank 111, thereby improving cleaning efficiency.

[0082] In some examples, the cross-sectional area of ​​the limiting part 162 gradually increases in the water outlet direction. In this example, by limiting the cross-sectional area of ​​the limiting part 162 to gradually increase, the cleaning fluid output from the limiting part 162 is arranged in a fan-shaped radial pattern, which allows the cleaning fluid to spray over a larger area and act on a larger surface, thereby improving the cleaning effect.

[0083] Please see Figures 1 to 8Based on the example of tray 10 described above, this application also proposes an example of a cleaning base station 100. The cleaning base station 100 includes a base station body 20, a dust collection fan 22, and a tray 10 as described in any of the above examples. The tray 10 is disposed on the base station body 20, and the dust collection fan 22 is used to supply gas to the air intake assembly 12. In this example, the tray 10 can be installed at the bottom of the base station body 20 so that when the cleaning robot docks on the cleaning base station 100, the cleaning robot's roller or cloth can be positioned above the tray 10, making it easier for the roller or cloth to move into the washing tank 111. The dust collection fan 22 can be a fan on the base station 100 used for cleaning the cleaning robot.

[0084] Based on the aforementioned cleaning base station 100, this application also proposes an example of a cleaning device. The cleaning device includes a cleaning robot and the cleaning base station 100 described above. The cleaning robot is used to clean the surface to be cleaned; the cleaning base station 100 is used to dock the cleaning robot.
