At this time, the cleaning roller 3 'provides the wiper strip 202' with a first frictional force rotating in the opposite direction of the second position T2, the elastic member 205 'provides the wiper strip 202' with a force rotating in the direction of the second position T2 'to keep the wiper strip 202' abutting on the outer surface of the cleaning roller 3 ', and the first rotation stopping rib 20151' prevents the wiper strip 202 'from passing the first position T1'. Under the combined action of the resilient member 205 ', the first rotation stopping rib 20151' and the cleaning roller 3 ', the scraper bar 204' is in the first position and the supporting diverter 2101 is at the first height H1.

As shown in fig. 10, when the user moves the switch housing 2103 to the right to abut the cover 204 ', the first inclined surface M1 separates from the second inclined surface M2, the left-right displacement of the slide block 2103 translates into the up-down displacement of the diverter 2101, the diverter 2101 moves downward, the diverter moves to the second height H2 and presses the wiper strip 202 ' to the second position T2 '. At this time, the cleaning roller 3 ' provides the wiper strip 202 ' with a frictional force for rotating toward the first position T1 ', the elastic member 206 ' provides the wiper strip 202 ' with a force for rotating toward the first position T1 ', and the second rotation stopping rib 20152 prevents the wiper strip 202 ' from passing the second position T2.
