A vaporizer device that uses a flame for vaporizing flavor and
psychoactive compounds from smoking materials such as tobacco. The
present device has a filter unit 34 with a porous flame filter 36. The
flame filter 36 can be made of open-cell ceramic or metal foam, sintered
ceramic or metal granules or other porous, heat resistant materials. In
use, flame is supplied to the flame filter, and inhalation causes ambient
air to enter the flame filter as well. The flame exhaust and ambient air
are mixed within the flame filter and produce an air stream of
intermediate temperature. The intermediate temperature air stream is hot
enough to vaporize desirable components from the smoking material, but
generally is not hot enough to burn the smoking material. The temperature
of the air stream can be controlled by adjusting the amount of flame
supplied to the flame filter 36.
