Abstract

Un mode de réalisation de la présente invention concerne un aspirateur comprenant : un corps principal comprenant une partie entrée d’air ; un canal interne formé dans le corps principal pour permettre à l’air introduit par la partie entrée d’air de s’écouler ; un dispositif de séparation de poussière couplé au corps principal de sorte à être amovible et comprenant une chambre de séparation de poussière destinée à séparer les substances étrangères de l’air s’écoulant à travers le canal interne ; et une unité de formation de canal disposée entre le canal interne et la chambre de séparation de poussière et comportant une surface inclinée destinée à changer le sens d’écoulement de l’air qui est passé à travers le canal interne. L’aspirateur selon l’invention est avantageux en ce qu’il réduit la perte d’écoulement d’air.
