Abstract: Cyclone collector including a body having an inlet (14) for drawing air, and a cyclone (1) inside of the body (12), having an outlet (14) for discharging air from the body, wherein the outlet (14) includes a passage portion having a passage, and a closed portion under the passage portion (142), the closed portion being closed.

Abstract: Cyclone collector including a primary cyclone (1) having a first inlet (14) for drawing external air, and a first outlet (14) for discharging air, a secondary cyclone (3) connected to the primary cyclone (1), and flow guide means (200) over the first outlet for preventing a flow direction of the air discharged from the first outlet (14) from turning sharply.

Abstract: An agitator (100) for a suction nozzle (10) in a vacuum cleaner is disclosed for largely improving efficiency of the vacuum cleaner, the agitator (100) including a body rotatably provided at an inlet (12) of the suction nozzle (10), and at least one blade assembly (120) including a plurality of blades (121) configured to come in contact with a surface to be cleaned, and mounted at the body (110) along a length direction thereof.

Abstract: A suction nozzle and a head of a cleaner having the same includes a suction hole to which a suction force is applied; an air channel formed as a closed region having predetermined area and depth and having the suction hole therein; and scraper longer than an end of an edge of the air channel, positioned in the air channel, and for scraping carpet fibers in cleaning a carpet. Especially when cleaning a carpet, the suction nozzle and the head of a cleaner having the same sufficiently push back carpet fibers to their root portions by the scraper to suck dust and alien substances, so that the carpet can be cleaned more cleanly, a suction path through which external air is introduced is formed in a direction that a cleaning proceeds, and thus dust or alien substances can be effectively removed.

Abstract: A dust separator of a cyclone type cleaner includes a first dust separator connected to a suction pipe, for separating dust from air by a centrifugal force for the first time; a collecting container connected to a lower portion of the first dust separator and in which the dust separated in the first dust separator is collected; and a second dust separator connected to an upper portion of the first dust separator, for sucking air which has passed through the dust separation in the first dust separator and separating dust from the air by a centrifugal force for the second time, so that an efficiency of collecting dust is improved without deteriorating a suction force of air.
