[0037] Intelligent home appliances, especially cleaning robots, are currently a hot topic. To meet user needs, current cleaning robots can not only perform cleaning but also work in conjunction with a matching base station to clean the robot.

[0038] However, when the base station cleans the cleaning unit of the cleaning robot, it is also necessary to determine the cleanliness of the cleaning unit in order to improve cleaning efficiency and enhance user experience.

[0039] To address the aforementioned technical problems, this application provides a base station for a cleaning device and a cleaning system.

[0040] The base station for the cleaning equipment provided in this application includes: a cleaning tank for cleaning the cleaning unit of the cleaning equipment; a suction pipe including a suction port and a discharge port, the suction port being located in the cleaning tank and the discharge port being connected to the inlet of the sewage tank; and a sewage detection device disposed on the sewage flow path, the sewage detection device being used to detect the cleanliness of the sewage.

[0041] This application utilizes a suction pipe to draw out and discharge wastewater from the cleaning tank. A wastewater detection device is installed along the wastewater flow path to detect the cleanliness of the wastewater. Therefore, this application demonstrates that the wastewater detection device can detect the cleanliness of the wastewater along its flow path, thereby providing a more accurate assessment of the cleanliness of the wastewater in the cleaning tank. Figure 1 Schematic diagrams of the cleaning system provided in some embodiments of this application; Figure 2 Schematic diagrams of the cleaning system provided in some embodiments of this application; Figure 3 A schematic diagram of the structure of a cleaning device provided for some embodiments of this application.

[0042] like Figures 1 to 3 As shown, the base station 10 of the cleaning equipment in this application can form a cleaning system 1 with the cleaning equipment 20. The cleaning equipment 20 can be used for cleaning, such as sweeping, mopping, or a combined sweeping and mopping function. The cleaning equipment 20 may include a cleaning unit, which may be a sweeping brush, a mop, etc. Figure 3 As shown, the mop can generally be installed at the bottom of the cleaning device 20, for example, it can be detachably installed on the mounting section 21. The detachable installation of the mop allows it to be replaced after it becomes damaged, worn out, or dirty.

[0043] like Figure 1 and Figure 2 As shown, the base station 10 of the cleaning equipment may include a cleaning tank 11, a suction pipe 12, and a wastewater detection device 13. The cleaning tank 11 may be located at the base station and is used to clean the cleaning unit of the cleaning equipment 20, typically located at the lower part of the base station 10. After the cleaning equipment 20 completes the cleaning operation, it returns to the base station 10, and the mop can enter the cleaning tank 11 for cleaning.

[0044] Figure 4 A perspective structural diagram of a base station for a cleaning device provided in some embodiments of this application, such as... Figure 4As shown, the base station 10 of the cleaning equipment may include a clean water tank and a wastewater tank, which can be respectively installed in the first receiving portion 110 and the second receiving portion 120 of the base station 10. The wastewater tank can be detachably disposed in the second receiving portion 120 of the base station body to facilitate removal of the wastewater tank for cleaning or wastewater discharge. In some embodiments, the wastewater tank can also be connected to a drainage pipe, allowing wastewater to be discharged directly without removing the wastewater tank.

[0045] Figure 5 Schematic diagrams of the suction pipe and sewage detection device provided for some embodiments of this application, such as... Figure 4 and Figure 5 As shown, the base station 10 may include a suction pipe 12, which may include a suction port 122, a discharge port 123, and a water storage section. The suction port 122 and the discharge port 123 may be located at opposite ends of the suction pipe 12. The suction port 122 may be located in the cleaning tank 11, and wastewater in the cleaning tank 11 may enter the suction pipe 12 through the suction port 122. The wastewater enters the suction pipe 12 through the suction port 122 and is then discharged from the discharge port 123. For example, the discharge port 123 may be connected to the inlet of a wastewater tank, so that wastewater in the cleaning tank 11 may be discharged into the wastewater tank through the suction pipe 12.

[0046] In this application, the path of wastewater flowing from the cleaning tank 11 through the suction port 122 to the discharge port 123 can be the wastewater flow path. The wastewater detection device 13 can be installed on the wastewater flow path.

[0047] In this application, the base station 10 may be equipped with a drive device for discharging wastewater from the cleaning tank into a wastewater tank through the suction pipe 12. The drive device may be a motor, a water pump, etc.

[0048] In this application, the wastewater flow path may include a water storage section. For example, the water storage section is located between the suction port 122 and the discharge port 123. During the process of wastewater discharge from the suction pipe 12, some wastewater will remain in the water storage section. Compared to other locations, the water storage section can retain wastewater for a relatively long time. The wastewater detection device 13 can be installed at the location of the water storage section. This arrangement allows the wastewater detection device 13 sufficient detection time to improve the accuracy of the detection results.

[0049] In some exemplary embodiments, the wastewater detection device 13 may be installed on the base station body. For example, such as Figure 4 As shown, the wastewater detection device 13 can be located on the side 102 of the base station 10. Specifically, the base station 10 can include a bottom wall 101 and a side wall 102. The bottom wall 101 can be the part of the base station 10 that is in contact with the ground when the base station 10 is in the installed state. The side wall 102 of the base station 10 can be the side that intersects with the bottom wall 101.

[0050] In some exemplary embodiments, the wastewater detection device 13 may be located on the side of the suction pipe 12, thereby detecting the cleanliness of the wastewater inside the suction pipe 12. By detecting the cleanliness of the wastewater inside the suction pipe 12, the cleanliness of the wastewater in the cleaning tank 11 can be determined. Thus, the cleanliness of the mop can be determined by the wastewater detection device 13, and based on the cleanliness of the mop, the wastewater detection device 13 can further control whether to continue cleaning the mop.

[0051] In this application, the wastewater detection device 13 can also be connected in series with the suction pipe 12, thus dividing the suction pipe into two sections. Based on the wastewater flow path, these two sections can be divided into an upstream section and a downstream section. With this configuration, wastewater must pass through the wastewater detection device 13 after flowing from the suction pipe 12, allowing the device to promptly obtain the cleanliness level of the wastewater within the suction pipe 12. Since the wastewater in the suction pipe 12 has not yet been discharged or entered into the wastewater tank, the cleanliness level of the wastewater in the suction pipe 12 can accurately reflect the cleanliness level of the wastewater in the cleaning tank 11.

[0052] In this application, the wastewater detection device 13 can also be connected in series downstream of the suction pipe 12. Thus, wastewater discharged through the suction pipe 12 can pass through the wastewater detection device 13 before being discharged or discharged into a wastewater tank. With this arrangement, the cleanliness of the wastewater downstream of the suction pipe 12 can be detected, thereby providing information on both the cleanliness of the wastewater in the cleaning tank 11 and the cleanliness of the wastewater before discharge or before entering the wastewater tank.

[0053] In this application, the suction pipe may include a bend. Due to the bend, the rate of sewage passing through the suction pipe is slowed down. The sewage detection device is located on the side of the suction pipe or connected in series with the suction pipe, and the detection results can be more accurate.

[0054] In some embodiments, the base station 10 may include a control module (not shown), which can be communicatively connected to the wastewater detection device 13. The wastewater detection device 13 can transmit clean data of the wastewater to the control module, which can then determine whether to continue cleaning the mop. Due to this precise control, the base station 10 can control whether to continue or stop cleaning the mop based on the cleanliness of the wastewater in the suction pipe 12. This setup ensures the mop is cleaned thoroughly when it is dirty, and reduces the frequency of mop cleaning when it is relatively clean, thus reducing water waste. In summary, it can be seen that the base station of this application controls the cleaning unit of the cleaning equipment, improving cleaning efficiency, enhancing user experience, and significantly saving water resources.

[0055] In some exemplary embodiments, the wastewater detection device 13 can be fitted onto the outer wall of the suction pipe 12. This arrangement reduces the distance between the wastewater detection device 13 and the suction pipe 12, which is beneficial for the accurate detection of wastewater by the device 13.

[0056] In some exemplary embodiments, the suction pipe 12 may include a light-transmitting portion, and the wastewater detection device 13 may be located on one side of the light-transmitting portion. The wastewater detection device 13 may include a light-emitting module and a detection module, the detection module including a turbidity sensor and / or a total dissolved solids sensor. However, this disclosure is not limited to detecting the cleanliness of wastewater by means of light; in some embodiments, the wastewater detection device 13 may be a device that detects wastewater using other methods.

[0057] In some exemplary embodiments, such as Figure 5 As shown, the bend 121 can be located between the suction port 122 and the discharge port 123. The wastewater detection device 13 can be located on the side between the bend 121 and the discharge port 123 of the suction pipe 12. The wastewater flows from the cleaning tank 11 through the suction port 122 into the suction pipe 12, and then through the discharge port 123 of the suction pipe 12 into the wastewater tank 15. It can be seen that in the wastewater flow path, the detection position of the wastewater detection device 13 is after the bend 121.

[0058] In this application, the bend 121 may include a higher pipe section, which is a segment of the bend 121 that is relatively higher than other parts in the gravity direction x. The highest point of the higher pipe section is set to be no higher than the height of the sewage outlet. The sewage detection device 13 can be located downstream of the higher pipe section, and the position of the sewage detection device 13 in the gravity direction x is no higher than the position of the higher pipe section. This arrangement ensures that the water storage area where the sewage detection device is located is always filled with sewage, and that there are no air bubbles in the sewage, thus preventing false detections by the sewage detection device.

[0059] In this application, the wastewater detection device 13 can be installed in the horizontal section or the rising section downstream of the elevated pipe section along the wastewater flow path. For example, the elevated pipe section may include a horizontally extending section called the horizontal section, or it may include a section extending upward in the gravity direction x called the rising section. The rising section can be formed as a rising section that rises vertically along the gravity direction x, or it can be formed as a rising section that rises at a certain inclination relative to the gravity direction x.

[0060] In some exemplary embodiments, such as Figures 5 to 8As shown, in the direction of gravity x, the position of the sewage detection device 13 is no higher than the top A of the bend 121. The so-called top A can be the highest point of the bend 121, that is, the highest point of the high-level pipe section. This setting ensures that the detection position of the sewage detection device 13 is always filled with sewage, and there are no air bubbles in the sewage, so that the sewage detection device 13 will not produce false judgments, thereby improving the detection accuracy of the sewage detection device 13.

[0061] In some exemplary embodiments, such as Figure 5 and Figure 8 As shown, the curved portion 121 can be configured to protrude upwards in the gravity direction x. This configuration can further slow down the flow rate of sewage, which is beneficial to improving the detection accuracy of the sewage detection device 13. However, this disclosure is not limited to this; in some embodiments, the curved portion 121 can be configured to protrude in any direction.

[0062] However, the curved portion 121 of this application is not limited to the above embodiments, such as... Figure 6 and Figure 7 In this case, the curved part can also bend downwards in the direction of gravity (x). For example... Figure 8 As shown, multiple bends 121 can be provided. Multiple bends 121 can be connected in sequence.

[0063] In some exemplary embodiments, such as Figure 5 As shown, the suction pipe 12 may include a first pipe section 124 and a second pipe section 125. The upstream end of the first pipe section 124 serves as the suction port 122, and the downstream end of the second pipe section 125 serves as the discharge port 123. A bend 121 connects the first pipe section 124 and the second pipe section 125. The upstream end of the bend 121 is connected to the downstream end of the first pipe section 124, and the downstream end of the bend 121 is connected to the upstream end of the second pipe section 125. The wastewater detection device 13 may be installed in the second pipe section 125 at a position no higher than the upper pipe section along the direction of gravity.

[0064] In this application, the hardness of the second pipe segment 125 can be greater than the hardness of the bend 121, and the second pipe segment 125 can be fixed to the side of the base station body. For example, in some embodiments, the bend 121 can be a flexible hose, which facilitates the installation of the bend 121. Specifically, in terms of manufacturing process, ordinary flexible hoses can be directly purchased and bent during installation to adaptably form the bend, without the need for additional molds or production lines for forming the bend. Furthermore, the use of a flexible hose also helps to extend the service life of the suction pipe 12.

[0065] In this application, as Figure 5As shown, the first pipe section 124 and the bend 121 can be integrated. For example, the same flexible hose can be used to install the first pipe section 124 and the bend 121.

[0066] In some exemplary embodiments, the suction pipe 12 can be detachably installed on the base station body, and can be disassembled, replaced or cleaned after the suction pipe 12 has been used for a certain period of time.

[0067] In some exemplary embodiments, such as Figure 4 As shown, the base station 10 may include a bracket 16, which can be used to support the curved portion 121. The bracket 16 helps to maintain the curved shape of the suction pipe 12 on the base station 10. That is, it facilitates the bending of the curved portion 121.

[0068] like Figure 4 As shown, the bracket 16 may include a first bracket 161 and a second bracket 162. The first bracket 161 and the second bracket 162 may be located on both sides of the curved portion 121 to support the curved portion 121. For example, the first bracket 161 may be located at the lower part of the curved portion 121 to support the curved portion 121, and the second bracket 162 may be located at the upper part of the curved portion 121, together with the first bracket 161, clamping the curved portion 121.

[0069] It should be noted that this application is not limited to Figure 4 In some embodiments, as shown, a bracket may be provided only at the lower part of the bent portion 121 or only at the upper part of the bent portion 121, as long as the bent portion 121 can be fixed.

[0070] In some exemplary embodiments, such as Figure 4 As shown, the suction pipe 12 can extend along the outer wall of the sewage tank 15, the bend 121 can be located on the side of the sewage tank 15, and the sewage detection device 13 can be disposed on the outer wall of the sewage tank 15. For example, the sewage detection device 13 can be fixed to the outer wall of the sewage tank 15.

[0071] In some exemplary embodiments, the wastewater detection device 13 is disposed on the side of the base station body by means of screw connection, snap connection, bonding or clamping connection, etc., and this disclosure does not impose specific limitations. Figure 5 As shown, the wastewater detection device 13 can be fixed by screws 14.

[0072] Based on the same concept, this application also provides a cleaning system 1, such as Figure 1 and Figure 2 As shown, the cleaning system may include a cleaning device 20 and a base station 10 for the cleaning device. The base station 10 for the cleaning device may be the same as the base station 10 shown in the previous embodiments, and will not be described again here.

[0073] This application describes a method where wastewater from a cleaning tank is drawn out via a suction pipe and discharged into a wastewater tank. A wastewater detection device is installed on the base station body and is used to detect the cleanliness of the wastewater within the suction pipe. Therefore, this application demonstrates that the wastewater detection device can detect the cleanliness of the wastewater before it enters the wastewater tank, thus providing a more accurate assessment of the cleanliness of the wastewater in the cleaning tank.

[0074] In this application, due to the bend in the pipe, the rate of sewage flow slows down as it passes through the suction pipe, and the sewage detection device is located on the side of the suction pipe, making the detection more accurate.

[0075] In some embodiments, the base station 10 may include a control module (not shown), which can be communicatively connected to the wastewater detection device 13. The wastewater detection device 13 can transmit clean data of the wastewater to the control module, which can then determine whether to continue cleaning the mop. Due to this precise control, the base station 10 can control whether to continue or stop cleaning the mop based on the cleanliness of the wastewater in the suction pipe 12. This setup ensures the mop is cleaned thoroughly when it is dirty, and reduces the frequency of mop cleaning when it is relatively clean, thus reducing water waste. In summary, it can be seen that the base station of this application controls the cleaning unit of the cleaning equipment, improving cleaning efficiency, enhancing user experience, and significantly saving water resources.

[0076] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and they should all be covered within the scope of the claims and specification of this application.
