An extract vaporizer has been disclosed. The vaporizer includes an adjustable-volume reservoir adapted to contain extract. The adjustable-volume reservoir is generally cylindrical. The vaporizer further includes a vaporization chamber. The reservoir and vaporization chamber are connected by a port. The vaporizer further includes a heating element proximal to the vaporization chamber. The vaporizer further includes a conduit adapted to ventilate the vaporization chamber.
1. An Extract vaporizer, comprising:
an adjustable-volume reservoir adapted to contain Extract, wherein said adjustable-volume reservoir comprises:
a cylinder top that is mechanically coupled to a first set of helical threads,
a cylinder bottom that is mechanically coupled to a second set of helical threads,
said first set of helical threads being coaxial with said cylinder top,
said second set of helical threads being coaxial with said cylinder bottom, and
said cylinder top and said cylinder bottom being slidably coupled to substantially enclose a reservoir volume,
a vaporization chamber, wherein said reservoir and said vaporization chamber being connected by a port,
a heating element proximal to said vaporization chamber, and
a conduit adapted to ventilate said vaporization chamber.
2. The Extract vaporizer of claim 1 , wherein said adjustable-volume reservoir is generally cylindrical.
3. The Extract vaporizer of claim 2 , wherein
said first and second sets of helical threads being capable of interacting to affect relative displacement of said cylinder top and said cylinder bottom, such that when said cylinder top is rotated with respect to said cylinder bottom, said first and second sets of helical threads will interact to adjust said volume of said adjustable-volume reservoir.
4. The Extract vaporizer of claim 1 , further comprising a plurality of visible relative displacement graduations.
5. The Extract vaporizer of claim 1 , wherein said heating element is an ohmic resistance heater.
6. The Extract vaporizer of claim 1 , wherein said vaporization chamber contains a porous solid element.
7. The Extract vaporizer of claim 6 , wherein said porous solid element is fritted glass.
8. An Extract vaporizer, comprising:
a reservoir adapted to contain Extract, wherein said reservoir substantially enclosing a volume,
a means for adjusting said volume of said reservoir,
a vaporization chamber, wherein said reservoir being in fluid communication with said vaporization chamber via a port,
a vaporization chamber heating means,
a conduit adapted to ventilate said vaporization chamber, and
a detent mechanism for providing tactile feedback.
9. The Extract vaporizer of claim 8 , further comprising:
a means for visually indicating said reservoir volume adjustment.
10. The Extract vaporizer of claim 8 , wherein said detent mechanism is capable of providing the tactile feedback for reservoir volume adjustment.
11. The Extract vaporizer of claim 8 , wherein said vaporization chamber contains a fritted glass element.
