Abstract: An apparatus for deodorizing dust particles includes a housing chamber, a powdering/granulating unit installed in the housing chamber, a deodorant disposed to be movable relative to the powdering/granulating unit, and a driving unit for driving the powdering/granulating unit or the deodorant. The deodorant is formed into granules or powders by a relative movement of the deodorant and the powdering/granulating unit, and thus obtained deodorant in granule or powder form is mixed with the dust particles.

Abstract: An electric blower includes an electric motor having a rotating shaft and an impeller fixed to the rotating shaft for rotation. The impeller has a rear shroud fixed to the rotating shaft, a front shroud which faces the rear shroud and has an inlet hole to take in air, a plurality of blades disposed between the rear shroud and the front shroud, and an inducer which streamlines air flowing from the inlet hole and has a three dimensional-shaped vane. The inducer is formed separately from the blade and is disposed between the rear shroud and the front shroud, whereby an electric blower that is simple in structure, lower in clearance between parts, higher in strength, and lower in air loss is realized. Also, a practicable vacuum cleaner high in sucking performance is realized by the utilization of the electric blower.
