[0049] Continuing to refer to FIG. 1, the liquid supply system further comprises a branch valve 31, a main flow channel 32 enabling the branch valve 31 to be in fluid communication with the first liquid supply nozzle 33, and a branch flow channel 34 enabling the branch valve 31 to be in fluid communication with the second liquid supply nozzle 35. Figure 5

[0050] ​​​The bypass valve 31 is located downstream of the liquid pump 30 and in fluid communication with the main flow channel 32 in terms of the flow direction of the cleaning liquid. The bypass valve 31 is configured to: when the first side portion 103 is in contact with the wall, connect the main flow channel 32 and the bypass flow channel 34 to provide the cleaning liquid to the second liquid supply nozzle 35; when the first side portion 103 is separated from the wall, block the fluid communication between the main flow channel 32 and the bypass flow channel 34.

[0051] The working principle of the surface cleaning device 100 is described as follows. When the surface cleaning device 100 is cleaning the ground far away from the wall, the liquid pump 30 is started, and the cleaning liquid in the solution tank 22 is distributed to the first liquid supply nozzle 33 under the action of the liquid pump 30. The driving device 14 is started to drive the brush roller 12 and the side brush 13 to rotate.

[0052] The suction motor 25 is started to form a negative pressure on the fluid path from the lower opening 181 to the suction motor 25. Under the action of the negative pressure, the dirty liquid at the lower opening 181 and the dirty liquid scraped by the second scraping strip 19 are guided to the dirty liquid recovery path and stored in the dirty liquid tank 23.

[0053] When the surface cleaning device 100 is close to the wall for cleaning, the liquid pump 30 is started, and the cleaning liquid in the solution tank 22 is distributed to the first liquid supply nozzle 33 under the action of the liquid pump 30. The driving device 14 is started to drive the brush roller 12 and the side brush 13 to rotate.

[0054] The liquid distribution device 31 is triggered to open, and the sealing member 15 is attached to the wall surface to close the opening 161 of the side brush cavity 16 and make the side brush cavity 16 semi-closed. Part of the cleaning liquid in the main flow channel 32 is transported to the second liquid supply nozzle 35 through the bypass flow channel 34, and the cleaning liquid of the second liquid supply nozzle 35 wets the cleaning member 132 of the side brush 13. The rotating cleaning member 132 cleans the surface (wall, ground, corner, etc.) contacted by the opening 161, the lower opening 162 and the front opening 163 of the side brush cavity 16. The cleaning liquid of the first liquid supply nozzle 33 wets the brush roller 12, and the brush roller 12 cleans the ground with the cleaning liquid.

[0055] The suction motor 25 is started to form a negative pressure on the fluid path from the lower opening 181 to the suction motor 25. The side brush cavity 16 is in communication with the lower opening 181 through the gap 1033 to form a stable negative pressure in the side brush cavity 16. Under the action of the negative pressure, the dirty liquid (including the wall and the ground) near the side brush cavity 16 enters the inside of the side brush cavity 16 and reaches the lower opening 181 through the gap 1033. The dirty liquid at the lower opening 181 and the dirty liquid scraped by the second scraping strip 19 are guided to the recovery path and stored in the dirty liquid tank 23 under the action of the negative pressure.

[0056] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit of the present application should be covered within the protection scope of the present application.
