Abstract

La présente invention concerne une station d'aspirateur. Un module de commutation de canal selon la présente invention comprend : un boîtier ; un tuyau de raccordement doté d'une fente qui se déplace le long de la circonférence interne du boîtier, et qui est sélectivement accouplé à une première partie de raccordement au canal d'aspirateur ou à une seconde partie de raccordement au canal d'aspirateur ; un moteur de commutation, qui est disposé sur un côté du boîtier et qui génère de l'énergie ; une came d'entraînement, qui est accouplée au moteur de commutation, qui comprend une unité de détection faisant saillie sur un côté et qui transmet de l'énergie au tuyau de raccordement ; et un capteur de position disposé sur un côté de l'unité de détection et comprenant un commutateur activé ou désactivé au moyen de l'unité de détection, de manière à détecter la position du tuyau de raccordement, et donc, la station d'aspiration comportant des premier et second liens qui déplacent le tuyau de raccordement, il est facile de déterminer si le tuyau de raccordement est accouplé à la première partie du canal d'aspiration ou à la seconde partie du canal d'aspiration et, simultanément, si le tuyau de raccordement est accouplé à la première partie du canal d'aspiration ou à la seconde partie du canal d'aspiration, même si un utilisateur ne réassemble pas directement le tuyau de raccordement.
