ASPIRATEUR DE POUSSIERE EQUIPE D'UN DISPOSITIF D'AFFICHAGE DU DEGRE DE REMPLISSAGE DE SON SAC REMPLACABLE COLLECTEUR DE POUSSIERE

L'INVENTION CONCERNE UN ASPIRATEUR DE POUSSIERE COMPORTANT UN DISPOSITIF AFFICHANT LE DEGRE DE REMPLISSAGE DE SON SAC COLLECTEUR.DANS LEDIT ASPIRATEUR, LE DISPOSITIF D'AFFICHAGE EST INFLUENCE PAR LA DIFFERENCE ENTRE LES PRESSIONS REGNANT AUX FACES INTERNE ET EXTERNE DU SAC COLLECTEUR 10 EQUIPE D'UNE PLAQUE DE SUPPORT RIGIDE 21 PERCEE DE DEUX ORIFICES. DANS L'UN D'EAU, EST EMBOITE LE MANCHON D'ASPIRATION 2 DE L'ASPIRATEUR, TANDIS QU'UN MANCHON 5 DE RACCORDEMENT A UN DISPOSITIF MANOMETRIQUE EST INTRODUIT DANS L'AUTRE DE CES ORIFICES. LESDITS ORIFICES SONT ENTOURES DE GARNITURES ELASTIQUES D'ETANCHEITE 7, 8.APPLICATION AUX ASPIRATEURS DE POUSSIERE. A vacuum cleaner has a housing with an inlet which can be closed by a cover. A dust bag can be installed in the housing suspended from a plate which is located inwardly of the cover and has two openings both of which communicate with the interior of the bag. The cover carries a suction nipple which sealingly enters one of the openings when the cover is closed. A connecting nipple is also carried by the cover and sealingly enters the other opening when the cover is closed. The entire connecting nipple, or a diaphragm mounted in the same, moves in direction towards the cover when, in response to increasing filling of the bag and clogging of the filter pores thereof, the pressure in the bag rises to a level higher than the pressure at the other side of the connecting nipple or diaphragm, respectively. This movement is transmitted to an indicator observable from the exterior of the vacuum cleaner and provides an indication of the degree to which the bag is filled.
