Vacuum cleaner with ultraviolet sterilization lamp

摘要

The cyclone-type dust collecting apparatus for a vacuum cleaner can reduce reverse flow of dirt and kill any bacteria in the dirt-collecting receptacle. The cyclone-type dust-collecting apparatus has a protruding flow path formed on the front side of the cyclone body and a lamp-positioning groove depressed inwardly at one side of the dirt-collecting receptacle for an ultraviolet lamp disposed in the cleaner body to apply ultraviolet rays radiated into the dirt-collecting receptacle. Accordingly, various bacteria inside the dirt collecting receptacle can be killed as the ultraviolet lamp disposed in the lamp positioning groove of the dirt collecting receptacle continuously applies the ultraviolet rays into the dirt collecting receptacle while the cleaner is on. Moreover, reverse flow of the dirt through the protruding flow path can be reduced as the storage level of the dirt stored near the protruding flow path of the dirt collecting receptacle is lowered and the space between the dirt near the protruding flow path of the dirt collecting receptacle and the cyclone body is expanded.
