Patent ID: 8362451

Claim:
A portable ultraviolet (UV) beam generator comprising: a housing extending in a longitudinal direction; an UV lamp having an elongated shape and installed in the longitudinal direction in the housing; a fan installed at a front end opening of the housing for cooling the UV lamp, the fan installed at an angle slanted from 95° to 170° relative to the longitudinal axis of the housing; a tilted plate installed in the housing at a rear side of the fan, the tilted plate inclined at an angle to direct an air flow from the fan in an upwardly inclined direction in the housing; and a guide partition installed in the housing at a rear side of the tilted plate, the guide partition having an open front end to receive the air flow there-through and defining an internal chamber in the housing, the internal chamber extending in the longitudinal direction of the housing and having the UV lamp installed therein, the internal chamber having its internal volume gradually reducing from a front side to a rear side thereof such that the air flow from the fan becomes faster as it approaches from the front side toward the rear side of the internal chamber to effectively cool the UV lamp installed therein.
