DUST EXTRACTOR COMPRISING A DUST CYCLONE CONTAINER ADJACENT TO A FINE FILTER SECTION WITH A BATTERY POWERED BLOWER/FAN MOTOR

Filed:2021-06-04Pub:2023-06-29
Applicant:HUSQVARNA AB

The present disclosure relates to dust extractor ( 1 ) comprising a dust cyclone container ( 3 ) having a contaminated portion downstream an air inlet ( 2 ) and a clean portion downstream the contaminated portion, and a dust separating part ( 9 ) there between. The contaminated portion is provided with a dust container ( 59 ). The dust extractor ( 1 ) comprises a fine filter section ( 12 ) arranged adjacent to the dust cyclone container ( 3 ) and having a contaminated section and a clean section downstream the contaminated section, and a fine filter part ( 15 ) is adapted to be provided between the contaminated section and the clean section. An air channel ( 47 ) runs between a clean side of the dust cyclone container ( 3 ) and a contaminated side of the fine filter part ( 15 ). The dust extractor also comprises a mobility section ( 66 ) comprising wheels and a blower/fan motor ( 10 ) for drawing air from the air inlet ( 2 ) through the dust extractor. The dust cyclone container ( 3 ) has a center axis ( 48 ) along its longitudinal extension, and the fine filter part ( 15 ) is provided at a radial distance from the dust cyclone container ( 3 ) along a plane (P) perpendicular to the center axis ( 48 ) of the dust cyclone container ( 3 ), the plane (P) coinciding with the dust cyclone container ( 3 ) and a portion of the fine filter part ( 15 ). The blower/fan motor ( 10 ) is adapted to be powered at least partly by at least one onboard battery ( 61 ), and preferably two batteries ( 61 ), wherein the at least one battery ( 61 ) is arranged to be received in at least one battery slot ( 62 ) provided in the fine filter section ( 12 ) or in the mobility section ( 66 ).
