Nozzle Unit

摘要

A nozzle unit (200) for a vacuum cleaner (10) is provided that can generate electrical energy by itself using air drawn in by the vacuum cleaner (10). The nozzle unit (200) includes an ultraviolet sterilizer (280) that radiates ultraviolet rays toward a surface being cleaned and sterilizes the surface, a lighting device (260) that emits light, a displaying device (270) that displays a cleaning state, a fan (220) that rotates by drawn in air, and a generator (230) that converts rotational energy of the fan (220) into electric energy so as to supply the electric energy to the ultraviolet sterilizer (280), the lighting device (260), and the displaying device (270).
