ABSTRACT:
A portable vaporizer including a base, a steam stack which includes a baffle and a cup for retaining a liquid, a vented collar, a steam cap and a boiling chamber. The boiling chamber includes a heating element adapted to vaporize a liquid received therein. The vapor exiting the boiling chamber rises through a plurality of openings in the vented collar and mixes with ambient air drawn in through a second set of openings, resulting in a temperature drop in the vapor. The mixture hits the baffle, thus breaking the fluid stream into smaller streams, resulting in a further reduction in the vapor temperature. Consequently, the vapor leaving the vaporizer is at a lower temperature than that discharged from the boiling chamber.
