Abstract

La présente invention fait appel à : un module de déplacement gauche/droite disposé entre une lèvre supérieure et une lèvre inférieure, qui fournissent une buse dans une lame d'air, de façon à pouvoir être déplacé dans la direction gauche/droite par une unité d'entraînement ; un premier élément de déplacement avant/arrière et un second élément de déplacement avant/arrière disposés à gauche et à droite sur le module de déplacement gauche/droite de façon à pouvoir être déplacés dans la direction avant/arrière, et comportant respectivement une première pointe de nettoyage de surface avant venant en contact avec une surface avant de la lèvre supérieure, et une seconde pointe de nettoyage de surface avant venant en contact avec une surface avant de la lèvre inférieure ; et un premier élément élastique ainsi qu'un second élément élastique qui, en utilisant une force élastique, maintiennent la première pointe de nettoyage de surface avant et la seconde pointe de nettoyage de surface avant dans l'état de contact étroit avec la surface avant de la lèvre supérieure et avec la surface avant de la lèvre inférieure.
