Abstract
(EN) A collection device includes a dust suction pipe (21), a first wind inlet passage, a first dust gathering chamber (22), and a first filter (23) provided in the first dust gathering chamber (22). The collection device also includes a second filter (25) provided in the first filter (23), a second wind inlet passage which connects the first filter (23) with the second filter (25), and a wind baffle plate (26) which radially separates the first filter (23) and the second filter (25). The second dust gathering chamber (24) is provided at the top end of the first filter (23). At least one of the first wind inlet passage and the second wind inlet passage is provided with an axially extended spiral structure. The collection device can increase dust collecting efficiency, applicability and airflow cleaning degree, extend service life of the filter, and reduce changing frequency of the filters and repairing cost. A vacuum cleaner having the collection device is also provided.
(FR) L'invention concerne un dispositif de ramassage qui comprend un tuyau (21) d'aspiration de la poussière, un premier canal d'entrée de courant d'air, une première chambre (22) pour ramasser la poussière et un premier filtre (23) disposé dans la première chambre (22) de ramassage de poussière. Le dispositif de ramassage comprend aussi un second filtre (25) disposé dans le premier filtre (23), un second canal d'entrée de courant d'air qui relie le premier filtre (23) au second filtre (25) et une chicane (26) de courant d'air qui sépare radialement le premier filtre (23) du second filtre (25). Une seconde chambre (24) de ramassage de poussière est disposée à l'extrémité supérieure du premier filtre (23). Le premier canal d'entrée de courant d'air et/ou le second canal d'entrée de courant d'air sont dotés d'une structure en spirale s'étendant axialement. Le dispositif de ramassage peut accroître l'efficacité du ramassage de poussière, le degré d'applicabilité et de nettoyage du courant d'air, prolonger la durée de vie du filtre et réduire la fréquence de changement des filtres et le coût de réparation. L'invention concerne aussi un aspirateur comportant ce dispositif de ramassage.
