Abstract

Un dispositif de ramassage de poussière est doté : d'un corps (1) ayant une ouverture d'aspiration (2) pour aspirer la poussière ; d'un souffleur électrique (11) qui génère un flux d'air d'aspiration ; d'une chambre de ramassage de poussière (3) qui reçoit la poussière aspirée par l'ouverture d'aspiration (2) ; et d'un passage d'écoulement interne (16) qui s'étend dans le corps (1) depuis l'ouverture d'aspiration (2) et qui comprend un conduit (14) et un passage (15). Le conduit (14) a une forme qui provoque la diminution progressive de la superficie transversale du conduit (14) depuis l'ouverture d'aspiration (2) vers le passage (15) à l'intérieur du corps (1). Du fait de cette configuration, le dispositif de ramassage de poussière transporte efficacement la poussière vers la chambre de ramassage de poussière (3).
