The flow distributor 26 and the flow resistance member 27 are both located in the second chamber of the roller chamber 25, and the flow resistance member 27 is located downstream of the flow distributor 26 and near the front of the lower opening 251 with respect to the rotational direction of the cleaning roller 23, and the flow distributor 26 is located downstream of the wiping roller edge 28. The top cover 22 is located outside the cleaning roller 23 and covers an upper portion and a partial front portion of the roller chamber 25, and the fluid dispenser 26 is located on an upper side of the cleaning roller 23 and is configured to be in fluid communication with the feeding path 33, the fluid dispenser 26 serving to dispense cleaning solution to the bristle layer of the cleaning roller 23.

Referring to fig. 8 and 10, the spoiler 27 is disposed on the top cover 22 and faces the cleaning roller 23. The spoiler 27 includes a base body 271 extending in the left-right direction, the base body 271 having an inner side surface 272 facing the cleaning roller 23 and fitting to the surface contour of the cleaning roller 23. The inner side surface 272 is arranged with a plurality of micro protrusions 273 and a plurality of connection ribs 274 connecting adjacent two micro protrusions 273. The flow preventing member 27 serves to prevent the excessive cleaning liquid from flowing out of the roller chamber 25 through the lower opening 251.

The connecting rib 274 extends towards the cleaning roller 22 and extends into the surface of the bristle layer of the cleaning roller 23, and the micro-protrusions 272 also extend towards the cleaning roller 22 and protrude relative to the connecting rib 274, wherein the connecting rib extends into the bristle layer 231 for 0-1mm, and the top end parts of the micro-protrusions 272 extend into the bristle layer 231 for 1-2mm. The plurality of micro-protrusions 273 are arranged in two rows in the vertical direction, and every two micro-protrusions 273 adjacent to each other in the horizontal direction are vertically shifted. The plurality of micro protrusions 273, the plurality of connecting ribs 274, a portion of the inner side surface 272, and the surface of the bristle layer 231 of the cleaning roller 23 collectively define a plurality of micro sumps 275 each having an upward opening, and the plurality of micro sumps 275 are capable of temporarily storing an excess of the cleaning liquid not absorbed by the bristle layer 231 to prevent the excess of the cleaning liquid from flowing out of the front portion of the lower opening 251.

As shown in fig. 6, the lower portion of the housing 21 is further provided with a flexible wiper strip 29, and the wiper strip 29 is located at the rear side of the lower opening 251 and is configured to contact the surface to be cleaned. The wiper strip 29 serves to collect the contaminated liquid on the surface to be cleaned at the lower side of the lower opening 251.

The operation of the surface cleaning apparatus 100 will now be described. When the surface cleaning apparatus 100 is used for cleaning, the transfer pump 32, the suction source 42 and the cleaning motor 233 are simultaneously activated, and the cleaning liquid in the tank 31 is supplied to the fluid dispenser 26 through the liquid supply passage 33 by the transfer pump 32. The fluid dispenser 26 dispenses the cleaning solution to the bristle layer of the cleaning roller 23, and the excess cleaning solution on the bristle layer of the cleaning roller 23 is scraped off by the flow-resisting member 27 and stored in the micro-reservoir 275. The cleaning roller 23 performs a cleaning operation on the surface to be cleaned with a cleaning liquid by the driving of the driving motor 29, and the dirty liquid on the surface to be cleaned is intercepted by the wiper strip 29 at the lower side of the lower opening 251. The dirty liquid carried by the cleaning roller 23 from the surface to be cleaned is scraped off by the roller edge brush 28 and drips down to the bottom of the base body 21. The suction source 42 forms a negative pressure on the recovery passage 43 and the first chamber, and the dirty liquid received at the bottom of the seat body 21 passes through the first chamber and the recovery passage 43 in sequence under the action of the negative pressure and is stored in the dirty liquid tank 41.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but various changes and modifications may be made without departing from the spirit and scope of the invention, the scope of which is defined by the appended claims, the description and the equivalents thereof.
