Patent ID: 8490627

Claim:
A device for vaporizing volatiles of a botanical substance, comprising: a) a pipe assembly having an inhalation air pathway and a reservoir positioned in the inhalation air pathway that is configured to receive the botanical substance to be vaporized; b) a heat exchanger assembly operatively coupled to the pipe assembly in communication with the inhalation air pathway, wherein the heat exchanger assembly has a substantially planar, non-porous heat exchanger member having a first face and an opposing second face in which the first face is configured to be exposed to a combustion source and combustion byproducts and the second face is exposed to the inhalation air pathway and wherein the non-porous heat exchanger member maintains separation of the inhalation air pathway from the combustion byproducts; and c) a substantially planar air guide spaced apart from the second face of the heat exchanger member so as to define at least one inlet pathway and at least one outlet pathway in communication with the inhalation air pathway of the pipe assembly.
