Abstract: The present invention relates to a cyclone unit and a contaminants-collecting apparatus having the same. The cyclone unit includes a cylindrical body disposed inside a dust-collecting receptacle; at least one supporting bracket extending from an outer circumferential surface of the cylindrical body to an inner circumferential surface of the dust collecting receptacle to support the cylindrical body and to separate the cylindrical body from the inner circumferential surface of the dust-collecting receptacle; and an air inlet pipe having one end in fluid communication with the air inlet port of the dust-collecting receptacle and the other end in fluid communication with the cylindrical body in a tangential direction.

Abstract: A dust collecting apparatus for a vacuum cleaner including a cyclone body provided with a cyclone chamber and a contaminant collecting chamber formed therein, a cyclone case provided in the cyclone body having the cyclone chamber and the contaminant collecting chamber separated from each other; an air inflow tube penetrating an outer wall of the cyclone body such that a suction passage at an outside of the cyclone body is fluidly communicated with a lower end of the cyclone chamber; and an air outlet tube penetrating sequentially a bottom of the cyclone case and a bottom the cyclone body to guide the air discharged from the cyclone chamber to a discharge passage placed at an outside of the cyclone body, wherein the contaminant collecting chamber is connected to the cyclone chamber through a contaminant discharge port formed at a side surface of upper end of the cyclone chamber.

Abstract: A suction nozzle of a vacuum cleaner includes jet units for jetting air into positions where air streams collide with each other as air is drawn into a suction port of the nozzle from both side portions thereof, so as to prevent substantially the collision of air streams.

Abstract: A suction brush for a vacuum cleaner including a body, the bottom side of which is formed with a suction port; a cover for covering the top side of the body; and an air jetting path for absorbing ambient air from the bottom side of the body and jetting the air toward a surface to be cleaned, to space the bottom side from the surface to be cleaned.

Abstract: A suction brush of a vacuum cleaner includes: a body configured to communicate with a dust collection device and including at least one suction port; a cover configured to cover a top of the body; and at least one rolling pin configured to be rotatably coupled at a bottom of the body.

Abstract: A vacuum cleaner includes: a main body; a suction brush configured to draw particulates into the main body; a motor installed at the main body; and a decelerating unit configured to connect a driving shaft of the motor with an impeller to transfer a rotation force of the driving shaft to the impeller and to set the rotation speed of the driving shaft lower than that of the impeller.
