ABSTRACT:
An intra-convertible thermal vapor extraction and delivery system comprising: an ergonomically-shaped casing comprising a heating element, a fan, an output nozzle thermally coupled to the heating element and having a nozzle base and a tapered nozzle end, and a nozzle sleeve; and a cradle having a bottom surface and a top surface, wherein bottom surface is substantially planar, and top surface is substantially concave so as to accept and securely hold the casing, wherein the fan is positioned substantially behind the heating element so as to blow ambient air through the element, heating it to a desired temperature, and forcing it through the output nozzle, and wherein the nozzle base is positioned to receive the air before the tapered nozzle end, and the nozzle base has a greater outer diameter than the tapered nozzle end, creating a step at the transition between the nozzle base and the tapered nozzle end.
