FIELD: engines and pumps. ^ SUBSTANCE: proposed dust capture device contains a primary dust capture unit, a secondary dust capture unit mounted on one side of the primary capture unit, a dust collector for collection of dust having been captured by the primary and the secondary dust capture units mounted on the bottom parts of both the primary and the secondary dust capture units. A dust capturing casing encapsules the primary and the secondary dust capture units and has an aperture on its bottom surface. The dust collector is detachably mounted on the dust capturing casing bottom surface. The primary and the secondary dust capture units are represented by cyclone-type dust capture units providing for turbulent motion of dust-laden air and separation of dust from the air; at least one of them (the primary one or the secondary one) is horizontally mounted. The dust collector is vertical mounted. The primary and the secondary dust capture units are positioned serially to provide for inlet of air supplied from the primary dust capture unit into the secondary dust capture unit. With the proposed design version the vacuum cleaner dust capture device contains a primary implement for separation of dust from the air, a secondary implement for separation of dust, positioned horizontally and designed so that to enable inlet of air supplied from the primary implement for separation of dust, a vertically positioned dust capture implement and a dust capture casing encapsuling the primary and the secondary implements for separation of dust and having an aperture on its bottom surface. The dust capture implement is detachably mounted on the dust capturing casing bottom surface. The primary and the secondary implements for separation of dust are represented by cyclone-type implements for separation of dust providing for turbulent motion of dust-laden air. ^ EFFECT: space-effectiveness of the dust capture device and the vacuum cleaner combined with improved dust capturing performance and increase of the dust collection reservoir volume without increase of the capture device overall dimensions. ^ 11 cl, 5 dwg |
