<p><P>PROBLEM TO BE SOLVED: To provide a suction brush for a vacuum cleaner, which is capable of preventing the suction force at the periphery of a suction inlet from being reduced while preferably maintaining operability of the suction brush when the suction brush moves forward. <P>SOLUTION: The suction brush for the vacuum cleaner includes front and rear blocking members 40 and 50 mounted to the bottom surface of a brush body 10 to seal off the periphery of a suction inlet 13a formed thereon and generate a high suction force between a surface D to be cleaned and the suction inlet during cleaning, wherein the front blocking member is pivotaly mounted to the brush body with their one ends connected to each other, and includes first and second blocking pieces 43 and 45 to maintain the high suction force between the suction inlet and the surface to be cleaned along with the rear blocking member, while being alternately brought into close contact with the surface to be cleaned when the brush body moves forwards or backwards; and the first blocking piece is formed with a plurality of air suction grooves 43a to restrict air flowing into the suction inlet while the first blocking piece is in close contact with the surface to be cleaned when the brush body moves forwards. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
