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.
Claims8
A vaporizer comprising:
- a base defining a reservoir for retaining a liquid;
- a boiling chamber comprising a housing which defines a hollow center, a top surface defining a vapor outlet, a bottom surface and a sidewall surface, the boiling chamber is received in and detachably mounted to the base such that liquid from the reservoir is received in the boiling chamber;
- a heating element received within the hollow center of the boiling chamber and adapted to induce evaporation of liquid in the boiling chamber;
- a vented collar disengagably mounted over the top surface of the boiling chamber, the vented collar defines a plurality of ambient air openings and a second plurality of openings juxtaposed thereto;
- a steam stack detachably mounted to the vented collar, the steam stack comprises a top surface defining a vapor outlet and a sidewall surface defining an open bottom and a hollow center;
- and
- a baffle received in the hollow center of the steam stack,
- whereby evaporated liquid exiting the boiling chamber rises through the second plurality of openings in the vented collar and mixes with ambient air drawn in through the ambient air openings, thus resulting in a temperature drop in the vapor;
- the mixture contacts the baffle, breaking the fluid stream into smaller fluid streams, resulting in a second temperature drop in the vapor.

- a heating element received within the hollow center of the boiling chamber and adapted to induce evaporation of liquid in the boiling chamber;
- a steam cap mounted to an upper end of the heating element and detachably mounted over the top surface of the boiling chamber, the steam cap defines a vapor discharge opening that is in fluid communication with the boiling chamber;
- a vented collar mounted over the steam cap, the vented collar defines a plurality of ambient air openings and a second plurality of openings juxtaposed thereto;
- a steam stack detachably mounted to the vented collar, the steam stack comprises a top surface defining a vapor outlet and a sidewall surface defining an open bottom and a hollow center;
- and
- a baffle received in the hollow center of the steam stack.
