Abstract

Un mécanisme de nettoyage comprend un orifice d'aspiration de conduit d'air (12) disposé sur un fond (11) d'un boîtier (1) et au moins une brosse de nettoyage (15) disposée sur le fond (11) du boîtier (1) et séparée de l'orifice d'aspiration de conduit d'air (12), chaque brosse de nettoyage (15) se déplaçant en va-et-vient lorsqu'elle est entraînée. Chaque brosse de nettoyage (15) effectue un mouvement de va-et-vient lorsqu'elle est entraînée à proximité et à l'opposé de l'orifice d'aspiration de conduit d'air (12). Chaque brosse de nettoyage (15) effectue un mouvement de va-et-vient dans sa propre direction d'axe (A1, A2) ou dans une direction (B1, B2) perpendiculaire à son propre axe. L'invention concerne en outre un robot de nettoyage. Le mécanisme de nettoyage et le robot de nettoyage peuvent résoudre efficacement des problèmes tels qu'un blocage d'aspiration de poussière provoqué par enroulement en raison de la présence d'une brosse principale roulante (108) dans un orifice d'aspiration d'air (107), et améliorent l'efficacité et l'effet d'aspiration de poussière.
