[0021] refer to Figure 1 , Figure 1 A cleaning system 100 is disclosed, comprising a surface cleaning device 10 and a base station for docking with the surface cleaning device 10. The base station is equipped with a dust collection motor. When the surface cleaning device 10 is docked with the base station, the airflow generated by the dust collection motor is used to transfer dirt in the dust cup assembly 2 through the dust discharge port 27 of the dust cup assembly 2 to the dust storage chamber of the base station.

[0022] refer to Figure 2-15 , Figure 2-4 A surface cleaning device 10 is disclosed, which is used to clean the surface to be cleaned. The surface cleaning device 10 shown in the figure is a robotic vacuum cleaner, capable of autonomously cleaning the surface. The working principle of robotic vacuum cleaners is well-established and will not be detailed here. Of course, the surface cleaning device 10 can also be other types of cleaning devices. See below for reference. Figure 5-9 The dust cup assembly 2 is described in detail below. The robotic vacuum cleaner includes a main body 1, which defines an installation space 11. The installation space 11 is used to install the dust cup assembly 2, and the interior of the dust cup assembly 2 defines a dust storage space 21 for containing dirt. A suction motor 3 is installed inside the main body 1. The suction motor 3 generates a suction airflow to collect dirt into the dust cup assembly 2 through a fluid channel. The dust cup assembly 2 also defines a receiving cavity 22, which is connected to the dust storage space 21 through a connecting port 25. A filter element 4 is installed in the connecting port 25. After the dust cup assembly 2 is installed in the installation space 11, at least part of the suction motor 3 is located in the receiving cavity 22. The suction port of the suction motor 3 is located at the connecting port 25. Thus, the suction airflow generated by the suction motor 3 enters the dust storage space 21 from the dust inlet 26 of the dust cup assembly 2 and is separated at the filter element 4. The dirt is retained in the dust storage space 21, and the airflow flows through the filter element 4, enters the suction port of the suction motor 3, and is then discharged from the suction motor 3. By adopting this structure, at least part of the suction motor 3 is placed in the receiving cavity 22 defined by the dust cup assembly 2, which can effectively utilize the internal space of the surface cleaning device 10 and increase the dust storage capacity of the dust cup assembly 2.

[0023] Continue to refer to Figure 5-15The dust cup assembly 2 includes a housing 23 and a cover 24, which together define an annular dust storage space 21. The housing 23 includes an inner wall 231, an outer wall 232, and a bottom wall 233. The inner wall 231, outer wall 232, and bottom wall 233 together define the annular dust storage space 21. The inner wall 231 is a boss structure 234, defining a receiving cavity 22. The receiving cavity 22 is used to receive a suction motor 3. A communication opening 25 is provided at the top of the inner wall 231, and the suction port of the suction motor 3 is located nearby. A mounting structure 5 is provided on the boss structure 234 for mounting a filter element 4.

[0024] Continue to refer to Figure 5-15 The cover 24 is placed on the housing 23, and the inner wall of the cover 24, the mounting structure 5, and the boss structure 234 together form a cavity for installing the filter element 4. The cover 24 can be opened, allowing the dirt in the dust storage space 21 to be emptied from the opening. After the cover 24 is opened, the user can also replace the filter element 4 through the opening. The annular dust storage space 21 is located on the outer periphery of the receiving cavity 22. At this time, the motor axis is basically in a vertical state. This facilitates the disassembly and assembly of the dust cup assembly 2. Of course, in other embodiments, the motor axis can also be at a certain angle relative to the height direction of the entire body 1 to adapt to different structural arrangements. The suction motor 3 is installed in the body 1 through the motor cover 6. The dust cup assembly 2 is covered outside the motor cover 6, that is, at least part of the motor cover 6 is disposed in the receiving cavity 22. The motor cover 6 defines an air inlet 61 and an air outlet 62. The air inlet 61 passes through the connecting port 25, and the filter element 4 is disposed near the air inlet 61. The opening of the air inlet 61 faces the second end 43 of the filter screen 41. This ensures that most of the airflow, after entering the dust storage space 21 from the dust inlet 26, flows along the extension direction of the filter screen 41, rather than directly entering the air inlet 61 from the first end 42 of the filter screen 41. After most of the airflow flows along the extension direction of the filter screen 41, it finally enters the suction motor 3 from the air inlet 61. In this way, as the airflow flows along the extension direction of the filter screen 41, most of the dirt first accumulates near the second end 43 of the filter screen 41, thus effectively utilizing the dust storage space 21.

[0025] refer to Figure 7 and 8 The filter element 4 includes a filter screen 41 and a filter HEPA filter 44 located downstream of the filter screen 41. The filter screen 41 extends around the air intake of the suction motor 3. This configuration not only effectively increases the filtration area without increasing the height of the filter element 4, but also effectively reduces the height of the robot vacuum cleaner, making it easier for it to enter relatively low spaces.

[0026] refer to Figure 7Along the extending direction of the filter screen 41, the filter screen 41 includes a first end 42 near the dust inlet 26 of the dust cup assembly 2 and a second end 43 away from the dust inlet 26, with a preset distance between the first end 42 and the dust inlet 26. The preset distance is generally between 3 and 10 centimeters. Setting a distance between the first end 42 of the filter screen 41 and the dust inlet 26 can effectively ensure that the airflow flows along the annular dust storage space 21 after exiting the dust inlet 26, thereby preventing dirt from accumulating at the dust inlet 26.

[0027] refer to Figure 8 Along the height direction of the dust cup assembly 2, the top of the filter screen 41 is higher than the top of the dust inlet 26. With this design, the airflow carrying dirt, especially heavier dirt, can quickly accumulate below the filter screen 41 after entering the dust storage space 21, which is conducive to the dust settling to the bottom of the dust storage space 21, and will not clog the filter screen 41 too quickly, causing a decrease in the suction power of the surface cleaning device 10.

[0028] refer to Figure 8 The dust cup assembly 2 also includes a dust discharge port 27, which is located near the second end 43 of the filter screen 41. This facilitates the transfer of dirt from the dust discharge port 27. By positioning the dust inlet 26 and the dust discharge port 27 at opposite ends of the filter screen 41, dirt can be effectively emptied from the entire dust storage space 21 during dust discharge.

[0029] Continue to refer to Figure 7 and 8 A guide surface 28 is provided between the second end 43 of the filter screen 41 and the dust inlet 26. The height of the guide surface 28 gradually increases along the direction from the dust outlet 27 to the dust inlet 26. There is a certain gap between the guide surface 28 and the cover 24, so that airflow can be ensured to flow over the guide surface 28 during dust collection, facilitating the removal of dirt from the guide surface 28. The presence of the guide surface 28 also allows the airflow to guide dirt and debris to gradually gather towards the second end 43 of the filter screen 41 during the operation of the sweeping robot, effectively improving the utilization rate of the dust storage space 21.

[0030] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
