Abstract

L'invention concerne un mécanisme de guidage de l'eau d'un rouleau de nettoyage (2), comprenant un support de guidage de l'eau (31) et une couche élastique (32) montée sur le support de guidage de l'eau (31), une chambre variable (5) étant prévue entre la couche élastique (32) et le support de guidage de l'eau (31). Le support de guidage de l'eau (31) met la couche élastique (32) en contact avec une surface du rouleau de nettoyage (2), de sorte qu'une certaine étanchéité est formée entre la couche élastique (32) et la surface du rouleau de nettoyage (2), et que les eaux usées pressées par le rouleau de nettoyage (2) peuvent être guidées vers une position appropriée. La couche élastique (32) peut fournir une certaine marge de déformation élastique, et la couche élastique (32) et le support de guidage de l'eau (31) peuvent fournir une plus grande marge de déformation entre eux, de sorte qu'il est possible de garantir que, lorsque la surface du rouleau de nettoyage (2) est usée en raison d'une utilisation prolongée, l'étanchéité peut encore être formée avec la surface du rouleau de nettoyage (2), évitant ainsi le phénomène de suintement des eaux usées au cours du processus d'utilisation, et prolongeant la durée de vie utile. En outre, comme la couche élastique (32) s'étend séparément dans la direction circonférentielle du rouleau de nettoyage (2) vers deux côtés, la surface de contact entre celle-ci et la surface du rouleau de nettoyage (2) est élargie, ce qui améliore encore l'étanchéité et augmente manifestement la résistance du rouleau de nettoyage (2).
