[0002] At present, the water circulation solutions of the sweeping robot system are mainly divided into manual water tank replacement solution and automatic water supply and drainage solution. The manual water tank replacement solution mainly sets up a clean water tank and a sewage tank in the base station of the sweeping robot system. The clean water tank requires the user to manually add water, and the sewage tank requires the user to manually pour water; the automatic water supply and drainage solution requires connecting to the tap water pipe and floor drain for the input of clean water and the output of sewage, and has high requirements on the installation environment. In fact, the automatic water supply and drainage solution also requires clean water tanks and sewage tanks in the base station for temporary storage of clean water and sewage, but their volume is relatively small compared to the manual water tank replacement solution.

[0003] Since a clean water tank and a sewage tank need to be set in the base station of the sweeping robot system, not only does the base station structure become more complicated, but users also need to operate the clean water tank and the sewage tank separately, and the maintenance process is relatively cumbersome.

[0044] In order to illustrate the technical solution of the present application, a description is given below with reference to specific drawings and embodiments.

[0045] Please refer to Figures 1 to 5 , Figure 1 is a schematic diagram of the structure of a sewage treatment device in one embodiment of the present application, Figure 2 yes Figure 1 The structural diagram of the cleaning element 10 in the sewage treatment device shown in FIG.

Figure 4 yes Figure 3A schematic structural diagram of the confluence member, the collecting member and the condensing member from another perspective, Figure 5 yes Figure 3 Schematic diagram of the structure of the collecting element shown.

[0046] In a first aspect, an embodiment of the present application provides a sewage treatment device, which is used in a base station of a sweeping robot system. The sweeping robot system may further include a sweeping robot, and the sweeping robot is provided with a mop.

[0047] The sewage treatment device comprises a cleaning element 10 , a heating element 20 , a confluence element 30 , a collecting element 40 and a clean water tank 50 .

[0048] The cleaning part 10 is provided with a cleaning tank 11, which is used to contain sewage. The cleaning tank 11 can also be used to contain a mop. The sweeping robot can use clean water in the cleaning tank 11 to clean the mop. After cleaning, the clean water becomes sewage and is contained in the cleaning tank 11. Sewage includes water and impurities insoluble in water.

[0049] The heating element 20 is used to heat the sewage in the cleaning tank 11 so that at least part of the sewage evaporates into water vapor.

[0050] The heating element 20 may include a heating wire, an electric heater or an electric heating tube, etc. The heating element 20 may be disposed at the bottom of the cleaning tank 11. After the heating element 20 heats the sewage in the cleaning tank 11, the water in the sewage evaporates into water vapor, and the impurities in the sewage are deposited at the bottom of the cleaning tank 11.

[0051] The confluence member 30 is disposed above the cleaning tank 11 , and the surface of the confluence member 30 facing the cleaning member 10 is a confluence surface 31 , and the confluence surface 31 is used for contacting with water vapor to condense the water vapor into liquid.

[0052] Specifically, after part of the sewage evaporates into water vapor, the water vapor rises and contacts the confluence surface 31. Since the temperature of the confluence surface 31 is generally low, the water vapor will condense into liquid. The liquid at this time is clean water without impurities, and the impurities can be collected by the dust collection component 80 of the base station.

[0053] The collecting member 40 is provided with a collecting groove 41, and the collecting groove 41 is used for collecting liquid.

[0054] For example, the collecting member 40 may be disposed below or at the edge of the confluence member 30, and the liquid on the confluence surface 31 may flow along the Figure 1 The liquid flows into the collecting tank 41 in the directions indicated by arrows A and B.

[0055] The clean water tank 50 is provided with a clean water chamber 51 , which is communicated with the collecting tank 41 and the cleaning tank 11 .

[0056] The liquid collected in the collecting tank 41 can be Figure 1 The direction indicated by the middle arrow C enters the clean water chamber 51, and the liquid in the clean water chamber 51 can flow along Figure 1 The direction indicated by arrows D and E enters the cleaning tank 11 for reuse, thereby enabling the reuse of sewage. The clean water tank 50 can be filled with water manually or directly connected to tap water.

[0057] As can be seen from the above, the sewage treatment device provided in the embodiment of the present application includes a cleaning part 10, a heating part 20, a conduit 30, a collecting part 40 and a clean water tank 50, so the sewage in the cleaning tank 11 can be heated by the heating part 20 first, so that at least part of the sewage evaporates into water vapor, and then the conduit surface 31 of the conduit 30 contacts the water vapor, so that the water vapor condenses into liquid, and the liquid is collected by the collecting tank 41 of the collecting part 40. Since the clean water chamber 51 of the clean water tank 50 is connected to the collecting tank 41, and the clean water chamber 51 is connected to the cleaning tank 11, the liquid collected by the collecting tank 41 of the collecting part 40 can enter the clean water chamber 51, and can continue to enter the cleaning tank 11 for reuse. The sewage treatment device provided in the embodiment of the present application does not need to set up a sewage tank separately, can simplify the structure of the base station, and is convenient for maintenance.

[0058] The sewage treatment device provided in the embodiment of the present application can directly utilize the existing cleaning part 10 of the base station and the space above the cleaning part 10 for modification, or can be separately set as a closed device. The sewage treatment device provided in the embodiment of the present application only requires the replacement or input of clean water in the clean water tank 50, and no additional intervention is required for the sewage; the integration is high, no additional modules are required, and the manufacturing cost is low.

[0059] Optionally, the middle of the converging surface 31 is convex relative to the edge of the converging surface 31 in a direction away from the cleaning element 10, and the collecting element 40 is arranged at the edge of the converging surface 31. In this way, the liquid condensed on the converging surface 31 can flow along the converging surface 31 from the middle of the converging surface 31 to the edge of the converging surface 31, so that it is convenient to use the collecting element 40 to collect it.

[0060] In this embodiment, the shape of the confluence member 30 can be set to be a semiconical shape, and the shape of the collecting member 40 can be set to be a semicircular ring shape. After the water vapor passes through the middle pore of the collecting member 40, it contacts the confluence surface 31. Such a configuration can make the structure of the sewage treatment device more compact.

[0061] In other embodiments, the collector 30 and the collector 40 may also be configured in other shapes, such as the collector 30 may be configured in a conical shape, and the collector 40 may be configured in a ring shape.

[0062] For example, see Figure 6 and Figure 7 , Figure 6 is a schematic structural diagram of a current collector 30 in another embodiment. Figure 7 It is a schematic structural diagram of a collecting member 40 in another embodiment.

[0063] In another embodiment, the collector 30 includes two collector plates 32 , the two collector plates 32 are connected at an angle, and the collecting groove 41 extends along a rectangular path.

[0064] Please refer to Figure 1 In some embodiments, the sewage treatment device includes a condensing element 60 , and the condensing element 60 is used to reduce the temperature of the confluence surface 31 .

[0065] By adopting the above solution, the water vapor can be condensed into liquid more quickly after contacting the converging surface 31, thereby improving the condensation efficiency.

[0066] For example, the condensing unit 60 may include a compressor, a condenser, an evaporator, a refrigerant, and the like.

[0067] Optionally, a plurality of condensing members 60 may be provided.

[0068] Please continue to refer to Figure 1 In some embodiments, the sewage treatment device further includes a vibration motor 70 , which is connected to the cleaning element 10 .

[0069] By adopting the above solution, it can be avoided that after part of the sewage in the cleaning tank 11 evaporates into water vapor, the remaining impurities in the cleaning tank 11 are adhered to the bottom of the cleaning tank 11 and cannot be collected by the dust collecting component 80.

[0070] Please refer to Figure 2 Optionally, the cleaning member 10 includes a main body 12 and an elastic deformation portion 13 connected to each other, and the elastic deformation portion 13 defines the bottom surface of the cleaning tank 11. In this way, when the vibration motor 70 is working, the vibration amplitude of the bottom surface of the cleaning tank 11 can be increased, and impurities can be further prevented from adhering to the bottom of the cleaning tank 11. Manual cleaning by the user is not required, and there is no obvious odor. The impurities remaining on the bottom surface of the cleaning tank 11 can be raised to form dust through the vibration of the vibration motor 70, which is convenient for subsequent dust collection by the dust collection component 80.

[0071] Specifically, the elastic deformation part 13 can be made of soft rubber materials such as silicone, rubber, etc. A plurality of vibration motors 70 can be provided.

[0072] Please refer to Figure 1In order to prevent the remaining impurities in the cleaning tank 11 from overflowing after part of the sewage in the cleaning tank 11 evaporates into water vapor, in some embodiments, the sewage treatment device includes a dust collecting component 80, which is connected to the cleaning tank 11 and is used to collect impurities in the cleaning tank 11.

[0073] By adopting the above solution, impurities in the cleaning tank 11 can be collected by the dust collecting assembly 80 to prevent the impurities from overflowing.

[0074] For example, after the vibration motor 70 vibrates to raise the impurities remaining on the bottom surface of the cleaning tank 11 to form dust, the dust in the cleaning tank 11 can be collected by the dust collecting assembly 80 to prevent the dust from overflowing.

[0075] Specifically, the dust collecting assembly 80 may include a dust collecting bag 81 and a fan 82. The dust collecting bag 81 is connected to the cleaning tank 11, and the fan 82 blows the impurities in the cleaning tank 11 along the dust collecting bag 81. Figure 1 The dust is sucked into the dust bag 81 in the direction indicated by the arrow M, and the fan 82 moves along Figure 1 The gas is discharged in the direction indicated by the arrow N.

[0076] Optionally, the sewage treatment device includes a dust cover (not shown in the figure), which can be opened and closed to cover the notch of the cleaning tank 11. Such an arrangement can further prevent the impurities in the cleaning tank 11 from overflowing.

[0077] For example, the dust cover and the cleaning member 10 can be detachably connected by magnetic adsorption connection, screw connection, bolt connection or snap connection, so that the dust cover can be opened and closed to cover the notch of the cleaning tank 11.

[0078] Please refer to Figure 1 and Figure 2 In some embodiments, the sewage treatment device includes a water level monitoring component and a first power component 90, the water level monitoring component is used to monitor the liquid level in the collection tank 41, and the first power component 90 is used to pump the liquid from the collection tank 41 to the clean water chamber 51.

[0079] By adopting the above solution, when the liquid level in the collecting tank 41 exceeds a threshold value, the first power member 90 can be used to pump the liquid from the collecting tank 41 to the clean water tank 50 to prevent the liquid from overflowing the collecting tank 41 .

[0080] Specifically, the water level monitoring component may include a liquid level gauge, and the first power component 90 may include a water pump or a vacuum pump, etc.

[0081] For example, the first power member 90 includes a vacuum air pump, which is connected to the clean water chamber 51 of the clean water tank 50. The clean water chamber 51 is connected to the collecting tank 41 through a pipeline. After the vacuum air pump is working, the air in the clean water chamber 51 is pumped along the Figure 1Pull out in the direction indicated by the arrow J and Figure 1 The liquid in the collecting tank 41 is discharged in the direction indicated by the arrow K, so that a negative pressure environment is formed in the clean water chamber 51, and the liquid in the collecting tank 41 flows along the Figure 1 The water flows into the clean water chamber 51 in the direction indicated by the middle arrow C.

[0082] Optionally, the sewage treatment device includes a second power member 91, which may include a water pump or a vacuum pump. The second power member 91 is used to transfer liquid from the clean water chamber 51 along the Figure 1 The water is pumped to the cleaning tank 11 in the direction indicated by the arrows D and E. In this embodiment, the second power member 91 includes a water pump.

[0083] In a second aspect, an embodiment of the present application provides a base station, which includes a sewage treatment device as in the first aspect.

[0084] The base station provided in the embodiment of the present application, since the sewage treatment device therein includes a cleaning part 10, a heating part 20, a conduit part 30, a collecting part 40 and a clean water tank 50, the sewage in the cleaning tank 11 can be heated by the heating part 20 first, so that part of the sewage evaporates into water vapor, and then the conduit surface 31 of the conduit part 30 contacts the water vapor, so that the water vapor condenses into liquid, and the liquid is collected by the collecting tank 41 of the collecting part 40. Since the clean water cavity 51 of the clean water tank 50 is connected to the collecting tank 41, and the clean water cavity 51 is connected to the cleaning tank 11, the liquid collected by the collecting tank 41 of the collecting part 40 can enter the clean water cavity 51, and can continue to enter the cleaning tank 11 for reuse. The base station provided in the embodiment of the present application does not need to set up a sewage tank separately, which can simplify the structure of the base station and facilitate maintenance.

[0085] In a third aspect, an embodiment of the present application provides a sweeping robot system, comprising a sweeping robot and a base station as in the second aspect.

[0086] In the sweeping robot system provided by the embodiment of the present application, since the sewage treatment device in the base station includes a cleaning part 10, a heating part 20, a confluence part 30, a collecting part 40 and a clean water tank 50, the sewage in the cleaning tank 11 can be heated by the heating part 20 first, so that at least part of the sewage evaporates into water vapor, and then the confluence surface 31 of the confluence part 30 contacts the water vapor, so that the water vapor condenses into liquid, and the liquid is collected by the collecting tank 41 of the collecting part 40. Since the clean water chamber 51 of the clean water tank 50 is connected to the collecting tank 41, and the clean water chamber 51 is connected to the cleaning tank 11, the liquid collected by the collecting tank 41 of the collecting part 40 can enter the clean water chamber 51, and can continue to enter the cleaning tank 11 for reuse. The sweeping robot system provided by the embodiment of the present application does not need to set up a sewage tank separately, can simplify the structure of the base station, and is convenient for maintenance.

[0087] The cleaning robot system provided in the embodiment of the present application includes the following process when in use:

[0088] First, the second power member 91 is used to pump liquid from the clean water chamber 51 to the cleaning tank 11 for cleaning the mop after the sweeping robot returns to the base station. After the mop is cleaned, the clean water will be converted into dirty sewage and remain in the cleaning tank 11.

[0089] Next, the sweeper temporarily leaves the base station and the evaporation recovery process starts, that is, the heating element 20 starts to work, so that part of the sewage evaporates into water vapor, and the confluence surface 31 contacts the water vapor to condense the water vapor into liquid. Under the action of gravity, the liquid flows along the confluence surface 31 to the collection tank 41.

[0090] When the liquid level in the collection tank 41 reaches a threshold, the first power member 90 operates to extract the air in the clean water chamber 51 , thereby forming a negative pressure environment in the clean water chamber 51 and allowing the liquid in the collection tank 41 to flow into the clean water chamber 51 .

[0091] Finally, the vibration motor 70 and the dust collecting assembly 80 are started, and the dust collecting assembly 80 sucks and collects the dust in the cleaning tank 11.

[0092] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
