摘要： A nozzle assembly of a vacuum cleaner is provided that includes a casing, a suction port, a drum brush, a fan, and a blocking plate. The drum brush is rotatably disposed in the casing so drum bristles hit a surface being cleaned. The fan is disposed in the casing to be rotated by air drawn in through the suction port so that the fan rotates the drum brush. The blocking plate is adjacent to the front of the fan to screen most of the fan except for a lower portion of the fan. The fan includes a circular fan body, a shaft member, and a plurality of blades. The inside edge of each of the blades is at a distance from the shaft member so that the drawn-in air passes through a space defined between the inside edge of each of the blades and the shaft member.
