Abstract
1,262,775. Dust-collecting suction apparatus. ELECTROLUX Ltd. 17 Oct., 1969 [8 Nov., 1968], No. 51156/69. Heading BIT. [Also in Division G1] A suction cleaner or floor polisher, wherein dust is drawn into the filter bag through a channel 11, has a signal device which indicates when the pressure drop across the bag exceeds a certain value, comprising a diaphragm 17 bearing on a ferro-magnetic flap 21, whose free end normally engages an annular magnet 28, closing aperture 30 which communicates with the ambient air through accoustic device 35. The diaphragm is subject to the pressures inside the filter bag and inside the cleaner/ polisher housing on its respective sides, and when the pressure difference is sufficient diaphragm 17 forces flap 21 suddenly away from the magnet, initiating the accoustic signal as air is drawn in through device 35.
