The side brush 13 has a brush holder 131, cleaning members 132 arranged on the brush holder 131, and an end 133 engageable with the recess 1032. The cleaning members 132 include bristle tufts 1321 arranged in clusters and a blade 1322 arranged in a sheet-like manner, the bristle tufts 1321 having a longer radial length than the wiper strip 1322. The connection of the connecting end portion 133 to the first end portion 10341 is designed as a pull-and-insert type connection structure, one of which is a socket and the other of which is a tab fitted to the socket, thereby facilitating the user to detach the side brush 13 from the outside of the first side portion 103. The horizontal axis line X2 of the side brush 13 is on the same straight line as the brush roller axis line X1 of the brush roller 12. In other embodiments, the side brushes and the brush roller may be arranged so that they are driven by different drive means or so that the horizontal axes of the side brushes are offset from the axis of the brush roller. The right end of brushroll 12 engages second end 10342 of pivot connection 1034 so that side brushes 13 are drivingly connected to brushroll 12 through pivot connection 1034.

In this example, the outside edges of the blades 1322 of the side brush 13 are substantially flush with the opening 161 to clean the contacted wall; some of the bristle tufts 1321 exit through the lower opening 162 of the side brush chamber 16 to clean the floor surface in contact therewith; part of the bristle tufts 1321 and part of the wiper 1322 pass through the front opening 163 of the side brush chamber 16 to achieve cleaning of the corners of the wall.

An alternative side brush 13' is shown in fig. 8, which alternative side brush 13' includes cleaning elements 132' secured to a holder 131' of the holder 131' all in tufts. The inner end of the brush holder 131 'has a connection end 133'. The connecting end 133' also mates with the end 10341 of the shaft coupling 1034.

As shown in FIG. 9, another alternative side brush 13", the alternative side brush 13" includes a cleaning member 132 "of a brush holder 131" fixed to the brush holder 131 "as a cleaning pad. The inner end of the brush holder 131 "has a connection end 133". The connecting end 133 "also mates with the end 10341 of the shaft coupling 1034.

In other embodiments, the cleaning elements may be tufts of bristles, or may be in the form of a wiping pad, sponge strip, in whole or in part.

As shown in fig. 10, the side brush 13 may be pulled out from the outside of the cleaning base 1 to clean the side brush 13, or the side brush 13 may be replaced with another type of side brush (e.g., a replacement side brush 13', a replacement side brush 13 ").

As shown in fig. 3 and 7, the sealing member 15, the front portion 1031, the side brushes 13 and the brush roller 12 are configured to constitute an assembly 200, and the assembly 200 is configured such that the assembly 200 can be detached from the housing 10 as a whole after the top cover 11 is removed from the housing 10. Wherein the side brush 13 is also configured to be separately detachable from the outside of the cleaning base 1, so that the user can replace or clean the side brush 13 conveniently.

With continued reference to FIG. 5, the liquid supply system further includes a branch valve 31, a main flow passage 32 fluidly connecting the branch valve 31 to a first supply nozzle 33, and a branch flow passage 34 fluidly connecting the branch valve 31 to a second supply nozzle 35.

The bypass valve 31 is located downstream of the liquid pump 30 with respect to the flow direction of the cleaning liquid and is in fluid communication with the main flow channel 32. The bypass valve 31 is configured to: when the first side 103 contacts the wall, the main channel 32 is communicated with the branch channel 34 to provide the cleaning liquid to the second liquid supply nozzle 35; when the first side 103 is separated from the wall, the primary channel 32 is blocked from fluid communication with the bypass channel 34.

The operation of the surface cleaning apparatus 100 will now be described. When the surface cleaning apparatus 100 is used for cleaning a floor surface remote from a wall, the liquid pump 30 is activated, and the cleaning liquid in the solution tank 22 is dispensed to the first nozzle 33 by the liquid pump 30. The drive means 14 is activated to simultaneously rotate the brush rolls 12 and the side brushes 13.

The suction motor 25 is activated and creates a negative pressure on the fluid path from the lower opening 181 to the suction motor 25. Under the negative pressure, the dirty liquid at the lower opening 181 and the dirty liquid scraped by the second wiper strip 19 reach the dirty liquid tank 23 through the dirty liquid recovery path and are stored therein.

When the surface cleaning apparatus 100 is used to clean a wall, the liquid pump 30 is activated and the cleaning liquid in the solution tank 22 is dispensed to the first nozzle 33 by the liquid pump 30. The drive means 14 is activated to simultaneously rotate the brush rolls 12 and the side brushes 13.

The liquid dispensing means 31 is triggered to open and the seal 15 is applied to the wall surface to close the open mouth 161 of the side brush chamber 16 and to render the side brush chamber 16 semi-closed. Part of the cleaning liquid in the main flow passage 32 is delivered to the second liquid supply nozzle 35 through the branch flow passage 34, the cleaning liquid of the second liquid supply nozzle 35 wets the cleaning member 132 of the side brush 13, and the rotating cleaning member 132 cleans the surface to be cleaned (wall, floor, corner, etc.) contacted through the opening 161, the lower opening 162 and the front opening 163 of the side brush chamber 16. The cleaning fluid from first fluid supply nozzle 33 wets brush roller 12, and brush roller 12 cleans the floor surface with the cleaning fluid.

The suction motor 25 is activated and creates a negative pressure on the fluid path from the lower opening 181 to the suction motor 25. The side brush chamber 16 communicates with the lower opening 181 through the notch 1033 to form a stable negative pressure in the side brush chamber 16. Under the action of the negative pressure, the dirty liquid (including the wall and the floor) near the side brush chamber 16 enters the inside of the side brush chamber 16 and reaches the lower opening 181 through the notch 1033. The dirty liquid at the lower opening 181 and the dirty liquid scraped by the second wiper strip 19 reach and are stored in the dirty liquid tank 23 through the recovery path by the negative pressure.

The above embodiments are only for illustrating the technical idea and features of the present invention, and the purpose of the present invention is to enable those skilled in the art to understand the content of the present invention and implement the present invention, and not to limit the protection scope of the present invention by this means. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
