FIELD: designs of vacuum cleaners.
SUBSTANCE: cyclone dust trap includes housing of cyclone having inlet air duct through which dust-laden air is fed to housing of cyclone. At least part of air sucked to housing of cyclone generates vortex flow. Housing of cyclone has outlet air duct communicated with unit for creating evacuation in order to suck air through outlet air duct out of vortex flow. Housing of cyclone also has flow-through guiding member arranged in outlet air duct, spaced from inlet of said duct and designed for lowering speed of air sucked through outlet air duct and for decreasing turbulence of air flow passing through said duct. Such cyclone dust trap is used in vacuum cleaner. Group of invention provides lowered sped of air sucked in inlet air duct.
EFFECT: lowered noise in outlet air duct of cyclone trap.
