Abstract

La présente invention concerne un filtre et un dispositif anti-poussière pour une boîtier d'ordinateur comportant une plaque latérale du boîtier (10), un ventilateur d'aspiration (6), une enveloppe de filtre (1), un capot supérieur (2) et un capot inférieur (3). Le capot supérieur (2) et le capot inférieur (3) sont fixés avec une vis pour former l'enveloppe de filtre (1), dans laquelle un conduit d'air est installé. Des orifices d'entrée d'air sont ménagés autour du capot supérieur (2). Une rainure circulaire centrale (12), une rainure annulaire interne (13) et une rainure annulaire externe (14) sont prévues dans le capot inférieur (3) respectivement. Des éponges de filtre à air sont installées dans la rainure circulaire centrale (12), la rainure annulaire interne (13) et la rainure annulaire externe (14). Cette structure combine un triple filtre d'air avec un ventilateur d'aspiration pour résoudre efficacement un problème d'épuration d'air dans le boîtier d'ordinateur, afin de protéger les éléments électroniques d'un ordinateur contre l'érosion entraînée par la poussière nuisible et prolonger la durée de vie d'un ordinateur. Dans le même temps, la structure est pratique pour l'assemblage et le désassemblage, et facilite le lavage et le remplacement des éponges de filtre.
