Abstract

L'invention concerne une buse d'aspiration (12) pour un appareil (10) d'aspiration pour surfaces dures portatif comprenant : un boîtier de buse d'aspiration (30), dans lequel un canal d'aspiration (38) est disposé et sur la face frontale de boîtier (40) dudit boîtier une raclette (44) élastiquement déformable et une lèvre de support (46) élastiquement déformable sont disposées, lesquelles font saillie à partir du boîtier de buse d'aspiration (30) et lesquelles définissent entre elles une chambre d'aspiration (80) à laquelle le canal d'aspiration (38) est raccordé, la raclette (44) comportant un bord de raclette (54), faisant saillie à partir de la zone d'extrémité avant du boîtier de buse d'aspiration (30) et la lèvre de support (46) comportant un bord de lèvre de support (56), dans sa zone d'extrémité avant, faisant saillie à partir de la buse d'aspiration (30), le bord de raclette (54) étant disposé, par rapport à une direction de raclage (108) de la buse d'aspiration (12), en aval du bord de lèvre de support (56) et la lèvre de support (46) comportant au moins une ouverture. L'invention vise à perfectionner la buse d'aspiration (12) de telle sorte qu'un résultat de nettoyage amélioré peut être obtenu. A cet effet, la raclette (44) comporte une section longitudinale (50) qui fait saillie vers l'avant à partir de la face frontale de boîtier (40) dans la direction opposée au canal d'aspiration (38) et qui est prolongée par au moins un appendice de raclette (52), lequel est incliné vers la section longitudinale (50) dans la position initiale non déformée de la raclette (44), l'appendice formant, à son extrémité libre, un bord de la raclette (54). L'invention concerne en outre un appareil d'aspiration pour surfaces dures portable et doté d'une telle buse d'aspiration.
