FIELD: engines and pumps. ^ SUBSTANCE: cyclone device for extracting dust out of sucked in outer air and outlet of a cleaned air is designed for vacuum cleaner. The device consists of at least one the first cyclone case of a cylinder shape creating the first cyclone camera wherein outer air circulates, and at least one the second cyclone case creating the second cyclone camera wherein air discharged out of the first cyclone camera is forced to circulate for dust extraction. Outer air is sucked through a lower end of the first cyclone camera and discharged through an upper end of the first cyclone camera, while air discharged out of the first cyclone camera is sucked through an upper end of the second cyclone camera and is discharged through an upper end of the second cyclone camera. An inlet aperture for air suction into the first cyclone camera of the first cyclone runs through the lower end of the first cyclone case. The device comprises discharge pipe extending from the upper end of the first cyclone camera to the lower end of the first cyclone camera and partially installed inside the first cyclone camera, and pipe having the first outlet aperture for discharge of air cleaned in the first cyclone camera. The first aperture for the dust discharge, separated by the first cyclone camera, is located in the upper portion of the first cyclone camera on its upper periphery. Dust having passed through the first aperture for the dust discharge, is collected in the first dust collector. The first outlet aperture is situated lower than the first aperture for dust discharge. ^ EFFECT: reduces losses of suction force; eliminates collision of flows; reduces noise and increases efficiency of air cleaning. ^ 22 cl, 7 dwg |
