Abstract

L'invention est constitué d'un dispositif qui est placé à l'intérieur d'appareils qui aspirent de l'air à l'aide de ventilateurs, dans ce cas spécifique à l'intérieur d'un sèche-cheveux; il exploite rationnellement les flux d'air produits par l'aspiration et les dépressions créées par le dispositif pour acheminer l'air et les particules étrangères dissoutes dans celui-ci dans les zones de sortie constituées d'un conduit doté d'une nouvelle forme de cône tronqué convexe creux qui change les dépressions à l'intérieur de l'appareil, agit comme un filtre mécanique et génère une éjection facile et automatique de la poussière filtrée vers l'ouverture d'aspiration de l'appareil. Grâce au dispositif qui fait l'objet de la présente invention, l'appareil est protégé de la poussière et, par conséquent, des défaillances et de l'usure.
