FIELD: personal use articles. ^ SUBSTANCE: double cyclone dust-collecting device may be used in vacuum cleaner. Dust-collecting device comprises a body of cyclone, including air suction to suck in ambient air, two cyclone chambers that swirl ambient air and separate dirt or dust, two dust-collecting chambers, which are arranged as separated in parallel relative to cyclone chambers, and dirt or dust separated from ambient air is collected, and two outlets for air, where ambient air is released from cyclone chambers. Air suction is arranged in lower part of cyclone body, and air outlet is provided in lower surface of cyclone chamber. Each cyclone chamber comprises a discharge pipe, which protrudes from lower surface of cyclone chamber, and is connected to air outlet, and alignment pipe passing from upper surface of cyclone chamber and supporting swirling force of air, which arises in cyclone chamber. ^ EFFECT: development of more intense suction force in device, prevention of return of dust collected in dust-collecting chambers and compactness of device with small height. ^ 12 cl, 9 dwg |
