[0039] The present application discloses a cleaning system 100, which includes a surface cleaning device 101 and a base station 102. The surface cleaning device 101 is used to clean a surface to be cleaned. The surface cleaning device 101 includes a suction motor 11 for generating a suction airflow and a dust cup 12 for storing dirt. The suction airflow recycles dirt on the surface to be cleaned into the dust cup 12. Figure 1 and 2 The surface cleaning device 101 may be a handheld vacuum cleaner, an upright vacuum cleaner, a horizontal vacuum cleaner or a sweeping robot, which is only used as an example and is not a clear limitation. The base station 102 is used to connect to the surface cleaning device 101. The base station 102 includes a dust storage space 21, which is used to accommodate dirt transferred from the dust cup 12. A dust bag may be provided in the dust storage space 21, and a container with a separation device may also be provided.

In this embodiment, no fan is provided in the base station 102, and the dirt in the dust cup 12 is transferred to the dust storage space 21 of the base station 102, which requires the airflow generated by the suction motor 11 to be realized. In order to achieve the above functions, a three-way structure 13 is provided upstream of the suction port 111 of the suction motor 11, and the three-way structure 13 includes a first air inlet 131, a second air inlet 132 and an air outlet 133. The first air inlet 131 is fluidly connected to the dust cup 12 to form a first air duct (refer to Fig.13 , the arrow direction in the figure is the gas flow direction), the first air duct is the suction air duct when the surface cleaning device 101 is used alone, in order to clean the surface to be cleaned. The second air inlet 132 is fluidly connected to the dust storage space 21 to form a second air duct (reference Fig.14 and 15, the direction of the arrow in the figure is the direction of airflow), the second air duct is turned on after the surface cleaning device 101 is docked to the base station 102, and the airflow generated by the suction motor 11 passes through the second air duct, so that the dust storage space 21 in the base station 102 generates negative pressure, and then the dirt in the dust cup 12 is transferred to the base station 102. Only one of the first air duct and the second air duct can be connected. The air outlet 133 is fluidly connected to the suction port 111. When the surface cleaning device 101 is docked to the base station 102, the first air duct is cut off and the second air duct is turned on. The base station 102 includes a first docking area 22, and a channel 26 for connecting the second air inlet 132 and the dust storage space 21 is provided in the first docking area 22. The base station 102 includes a second docking area 23, and the second docking area 23 is used to dock the dust cup 12. The bottom cover of the dust cup 12 can be opened, thereby connecting the dust cup 12 and the dust storage space 21 of the base station 102. In order to redirect the airflow generated by the suction motor 11, the surface cleaning device 101 also includes an air duct switching component 14. The air duct switching component 14 is configured to: after the surface cleaning device 101 is docked to the base station 102, the first air inlet 131 is closed, and the second air inlet 132 is opened at the same time, at this time, the second air duct is connected. After the surface cleaning device 101 leaves the base station 102, the first air inlet 131 is opened, and the second air inlet 132 is closed at the same time, at this time, the first air duct is connected. In this way, when the surface cleaning device 101 is docked to the base station 102, the two air ducts are switched between each other without the need for manual operation, and there is no need to set up additional components to control the air duct switching component 14.

[0041] refer to Figure 6-12 In a specific embodiment, the air duct switching assembly 14 includes a first connecting rod 141, a second connecting rod 142 connected to the first connecting rod 141, and a closed structure 143 connected to the second connecting rod 142. The first connecting rod 141 rotates to drive the second connecting rod 142, so that the second connecting rod 142 drives the closed structure 143 to close the first air inlet 131 or the second air inlet 132. The transmission end 147 of the second connecting rod 142 is connected to the linkage end 146, and the fixed end 148 of the second connecting rod 142 is fixedly connected to the closed structure 143, so that the second connecting rod 142 drives the closed structure 143 to rotate around the second pivot structure 149; wherein, when the linkage end 146 rotates around the first pivot structure 144, it drives the second connecting rod 142 to rotate around the second pivot structure 149.

The rotating arm 156 is fixedly connected to the second connecting rod 142. When the second connecting rod 142 rotates, the rotating arm 156 rotates with the second connecting rod 142, and the closed plate 157 rotates with the rotating arm 156 to achieve the switching of the air duct. The first connecting rod 141 is installed in the surface cleaning device 101 through the first pivot structure 144. The first connecting rod 141 includes a butt end 145 and a linkage end 146 respectively located at both ends of the first pivot structure 144.

The reset structure is configured to move the closed structure 143 from the position where the first air inlet 131 is closed to the position where the second air inlet 132 is closed and remain in this position after the surface cleaning device 101 leaves the base station 102. The reset structure can be a spring, one end of the spring is fixed to the first connecting rod 141, and the other end of the spring is fixed in the surface cleaning device 101. The reset structure can also be a torsion spring, which is arranged at the first pivot structure 144. The reset of the air duct switching component 14 is achieved by the elastic force of the spring or the torsion spring.

The air duct switching assembly 14 is generally arranged inside the surface cleaning device 101. When docked to the base station 102, the push rod structure 25 extends into the guide hole of the surface cleaning device 101 to push the first connecting rod 141. A charging structure 24 and a pushing structure for pushing the first connecting rod 141 are also arranged in the first docking area 22 of the base station 102. Arranging the charging structure 24, the pushing structure, etc. in one area can not only save space, but also play a role in positioning, making it convenient for users to dock the surface cleaning device 101 to the base station 102.
