Abstract
A portable air purifier may include at least one blower fan which rotates with respect to a rotational shaft extending in a first direction, and includes a hub, and a plurality of fan blades radially connected around the hub; and a fan cover provided with at least one shielding plate that shields the hub, and a plurality of guide vanes that guides a discharge direction of air discharged by the at least one blower fan. A foreground of a rotational area of the plurality of fan blades forms a blowing surface, and the plurality of guide vanes may be arranged in front of the blowing surface and extend radially with respect to the rotational shaft. Each of the plurality of guide vanes may include a first guide surface positioned adjacent to the at least one blower fan and a second guide surface connected to the first guide surface and positioned further from the at least one blower fan than the first guide surface. The second guide surface may extend parallel to the first guide surface. The first guide surface may be oriented at a predetermined angle with respect to the blowing surface.
