[0047] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0048] With reference to Figures 1-19, and in particular with reference to Figures 1, 2, and 4, the present application discloses a cleaning system, which includes a surface cleaning device 101 and a base station 102 docked therewith. After the surface cleaning device 101 is docked to the base station 102, it can perform self-cleaning. In order to make it more convenient for users to use, and to avoid leaving dirt on the ground after the surface cleaning device 101 stops, the surface cleaning device 101 can be driven by the user into the base station 102, and the user does not need to stop the device and then lift the device and then place it into the base station 102. The base station 102 includes a charging bracket 103 and a tray 104. The charging bracket 103 can charge the device, and the tray 104 can be detachably connected to the base station 102. An inclined opening is provided on one side of the tray 104, and the surface cleaning device 101 can be driven from the opening to the tray 104. After the user stands the surface cleaning device 101 upright, the surface cleaning device 101 can be controlled to perform self-cleaning.

[0049] The surface cleaning device 101 is used to clean the surface to be cleaned. The surface cleaning device 101 includes a dirt recovery system, which includes a suction motor 4 for generating a suction airflow and a recovery tank 1 for recovering dirt. The surface cleaning device 101 also includes a cleaning liquid supply system, which includes a cleaning liquid tank 3. In one embodiment, the cleaning liquid tank 3 and the recovery tank 1 are integrally formed (see Figure 5). The surface cleaning device 101 may also include a water pump for delivering liquid from the cleaning liquid tank 3 to the surface to be cleaned or to the cleaning head 30. To ensure a more thorough cleaning, the cleaning liquid supply system also includes an electrolytic water assembly for generating a sterilizing liquid that can sterilize the roller brush or the surface to be cleaned. The electrolytic water assembly can be located within the cleaning liquid tank 3 or in the pipeline between the water pump and the cleaning liquid tank 3. In one specific embodiment, the electrolytic water assembly is located within the cleaning head 30 and includes a window through which the user can clearly see bubbles generated by the electrolytic water assembly.

[0050] With reference to Figures 5-7, and also with reference to Figures 15-19, the surface cleaning device 101 generally includes a main body 10 and a cleaning head 30 and a handle 20 located at both ends of the main body 10. Since the surface cleaning device 101 is a wet cleaning device, its waterproof performance needs to be better than that of an ordinary vacuum cleaner. A battery assembly 5 for powering the suction motor 4 is provided in the main body 10. A first cavity 21 for accommodating the battery assembly 5 and a receiving space 22 for accommodating a container are defined in the main body 10. The battery assembly 5 includes a battery pack 52 and a circuit board 51. The circuit board 51 is integrated with a cell controller for controlling the battery pack 52 and a motor controller for controlling the suction motor 4. The container can be a recycling box 1 or a cleaning liquid tank 3. Of course, in one embodiment, the recycling box 1 and the cleaning liquid tank 3 can be integrally formed and placed together in the receiving space 22, which can effectively save space. Furthermore, only one receiving space 22 is required to accommodate two containers at the same time, which can improve the waterproof performance of the main body 10.

[0051] Referring to Figures 8-14, the recovery tank 1 is provided with a separation device 19, which also includes a filter 14 for solid-liquid separation. The filter 14 is mounted on a support plate 122, which has a connecting hole 168 formed therein. A baffle 121 is positioned at the connecting hole 168. The baffle 121 prevents liquid below the baffle 121 from flowing back into the area where the filter 14 is located. When the recovery tank 1 is in a flat position (i.e., when the main body 10 is substantially parallel to the ground), the baffle 121 closes the connecting hole 168, preventing liquid from flowing back from the underside of the support plate 122. This prevents the suction motor 4 from drawing in large amounts of liquid when the device is in a flat position. The filter 14 can rotate relative to the support plate 122, but its rotation angle is less than 90 degrees, preferably less than 60 degrees or less than 45 degrees. The filter 14 is rotatable, primarily to allow the user to quickly remove any items stuck to it while cleaning it. To limit the rotation angle of the filter 14, the filter 14 includes a filter body 141 and a retaining structure 142 connected to the filter body 141. The retaining structure 142 can contact the support plate 122 to limit the rotation angle of the filter 14. When the filter 14 is installed in the cup 11 of the recycling bin 1, the retaining structure 142 can contact the cup 11 after rotating a certain angle, preventing the filter 14 from rotating excessively. Specifically, the filter 14 can rotate less when inside the cup 11 than when outside the cup 11. The advantage of this design is that when the recycling bin 1 is in normal use, the smaller the angle of rotation of the filter 14, the more likely solid waste will enter the area between the filter 14 and the support plate 122, especially when the recycling bin is in a flat position. Of course, the best design is that when the filter 14 is placed in the cup body 11, the filter 14 hardly rotates, and the filter 14 can only rotate after the separation device 19 is removed.

[0052] Referring to Figures 15-19, integrating the cell controller and the motor controller into a circuit board 51 can effectively save costs. At the same time, placing the battery pack 52 and the circuit board 51 together in the first cavity 21 for sealing can effectively improve the sealing effect. In order to achieve a better heat dissipation effect for the battery pack 52 and the circuit board 51, part of the heat can be taken away by the airflow discharged by the suction motor 4. Specifically, the first cavity 21 and the accommodating space 22 are separated only by the inner plate 25 of the main body 10. A circulation channel 26 is defined between the inner plate 25 and the container, and the airflow discharged by the suction motor 4 flows through the circulation channel 26 and then is discharged from the main body 10. Because the circulation channel 26 and the first cavity 21 are separated only by the inner plate 25, the heat in the first cavity 21 can be carried away by the airflow after being transferred to the inner plate 25, thereby playing a cooling role.

[0053] Referring to Figure 2, other controllers can also be integrated on the circuit board 51. The cleaning head 30 includes a roller brush and a drive motor 331 for driving the roller brush. The circuit board 51 is integrated with a drive controller for controlling the drive motor 331. It also includes a cleaning liquid supply system, which includes a cleaning liquid tank 3 and a water pump. The circuit board 51 is integrated with a supply controller for controlling the cleaning liquid supply system. The cleaning liquid supply system also includes an electrolytic water component. The circuit board 51 is integrated with an electrolytic water controller for controlling the electrolytic water component. Integrating multiple controllers onto a single circuit board 51 can more effectively solve the waterproofing problem.

[0054] Referring to Figures 5 and 6 , in one embodiment, after the recycling bin 1 is installed in the storage space 22, the cleaning liquid tank 3 is positioned between the inner panel 25 and the recycling bin 1. This design minimizes the space occupied by the cleaning liquid tank 3. The first cavity 21 is located directly in front of the storage space 22 along the travel direction of the surface cleaning device 101. Placing the container behind the battery assembly 5 shifts the center of gravity of the main body 10 as far forward as possible, making it relatively easy for the user to use the device. It also makes it easier for the user to access the recycling bin.

[0055] Referring to Figures 17-19, the main body 10 includes an outer housing 2, which is integrally formed. The outer housing 2 can be integrally molded or die-cast from a metal material. The outer housing 2 defines a first cavity 21 and a second cavity 23 located above the first cavity 21. The first cavity 21 includes a first opening 211, and the second cavity 23 includes a second opening 231. The first opening 211 and the second opening 231 are respectively arranged at opposite ends of the outer housing 2. The first opening 211 faces the location of the cleaning head 30, and the second opening 231 faces the location of the handle 20. When in use, the first opening 211 faces downward, because the liquid in most cases flows downward along the main body 10, which can effectively prevent the liquid from entering the first cavity 21 from the first opening 211. Meanwhile, the second opening 231 is located at the very top of the main body 10, which is the highest point of the main body 10 and is adjacent to the handle 20. At this position, contact with liquid is minimal. Therefore, positioning the opening toward the handle 20 facilitates installation of electrical components such as the suction motor 4 and display screen, and improves the waterproof performance of the main body 10. Furthermore, positioning the cleaning liquid tank 3 and the recovery tank 1 as close to the cleaning head 30 as possible effectively lowers the center of gravity of the entire main body 10, shifting it downward and closer to the cleaning head 30. This allows the cleaning head 30 to bear the majority of the weight of the main body 10, saving the user effort during use. To ensure tightness, the first opening 211 and the second opening 231 can be sealed.

[0056] Referring to Figures 15 and 16, in order to facilitate the installation of the circuit board 51 of the battery pack 52, the battery assembly 5 also includes a bracket 53. After the battery pack 52 and the circuit board 51 are installed on the bracket 53, they can be loaded into the first cavity 21 from the first opening 211. A sealing strip is also provided on the bracket 53, and the sealing strip is in contact with the inner wall of the outer casing 2 to seal the first opening 211. Specifically, the battery pack 52 can be welded and plugged into the circuit board 51 first, and then the two can be fixed together to the bracket 53. After the wiring harness is plugged into the circuit board 51, the battery assembly 5 can be installed in the first cavity 21. The wiring harness can extend to the outside through the wire hole and connect with other electrical components. The filter hole needs to be sealed, which can generally be sealed with glue, but other sealing methods can also be used.

[0057] The battery assembly 5 also includes a bracket 53 for mounting the battery pack 52 and / or circuit board 51. The bracket 53 is provided with at least one heat dissipation hole 531, allowing at least a portion of the battery pack 52 and / or circuit board 51 to directly face the inner panel 25. This arrangement effectively improves heat dissipation efficiency. The bracket 53 can also be a frame structure, and the battery pack 52 and circuit board 51 only need to be mounted on the bracket 53.

[0058] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
