Abstract

Systems, methods and apparatuses for vaporizing all or substantially all plant matter, liquid and/or other material to be vaporized are disclosed. Embodiments of the invention comprise a vaporization chamber sealed except for at least two conduits, heating element, a first conduit coupled to a source of fully or almost fully non-oxygenated gas, a heating element capable of heating the vaporization chamber to a temperature above a combustion temperature, a second conduit configured to transport vaporization gases and vaporized elements out of the vaporization chamber and at least one valve positioned in the second conduit preventing the flow of atmospheric air into the vaporization chamber. In some instances, the first gas substantially clears the vaporization chamber of atmospheric air prior to reaching combustion temperature. A second gas containing oxygen may be intermixed with the vaporization gases and vaporized elements proximal to the combustion chamber.

First claim

The invention claimed is:

1. A device for vaporization of compounds comprising:
a vaporization chamber for placement of the compounds, the vaporization chamber sealed during operation of the device, except for at least two conduits;
the vaporization chamber having a receptacle for the compounds;
a first conduit of the at least two conduits operably coupled to a first source of a first gas having a set amount of oxygen;
where the first gas is a compressed gas delivered at above ambient pressure;
a heating element capable of heating the vaporization chamber to a temperature above an upper temperature limit for vaporization that avoids combustion;
a second conduit of the at least two conduits, the second conduit configured to transport vaporized elements of the compounds out of the vaporization chamber; and
an oxygen detection mechanism located upstream of the vaporization chamber preventing the first gas from entering the vaporization chamber if the temperature in the vaporization chamber is above a threshold temperature for a level of oxygen in the first gas.

2. The device of claim 1 , wherein the set amount is substantially non-oxygenated.

3. The device of claim 1 , wherein the first gas is helium.

4. The device of claim 1 , wherein the first gas is nitrogen.

5. The device of claim 1 , wherein the first gas is argon.

6. The device of claim 1 , wherein a cooling element is downstream of the vaporization chamber, the cooling element configured to cool gas passing through it.

7. The device of claim 6 , wherein the cooling element comprises piping.

8. The device of claim 1 , wherein the heating is accomplished, at least in part, using resistance heating.

9. The device of claim 1 , wherein the set amount is an amount of oxygen insufficient to sustain combustion.

10. The device of claim 1 , wherein the receptacle contains unground cannabis.

11. The device of claim 1 , where a valve is present at the connection of the first gas source to a remainder of the system.

12. The device of claim 1 , where oxygenated gas is intermixed with the vaporized elements downstream of the vaporization chamber.

13. The device of claim 1 , where one or more of a combination code, passcode, retinal scan, fingerprint scan, or other biometric measurement is required prior to actuation of the heating element.

14. The device of claim 1 , where an intake is present in a portion of the device downstream of the vaporization chamber, which intake provides a source of atmospheric oxygen and is controlled by blocking the intake with a finger.

15. The device of claim 1 , where the temperature in the vaporization chamber gradually rises to a temperature where there is a risk of denaturing one or more of desired molecules being vaporized.

16. The device of claim 1 , where portions of plant matter that accumulate on parts of devices used to aerosolize plant matter are heated within the device to a temperature where some or all of those portions of plant matter become aerosolized.

17. A device for vaporization of compounds comprising:
a vaporization chamber for placement of the compounds, the vaporization chamber sealed during operation of the device, except for at least two conduits;
the vaporization chamber containing unground cannabis flower;
a first conduit of the at least two conduits operably coupled to a first source of a helium gas;
where the helium gas is compressed and delivered at above ambient pressure;
a heating element capable of heating the vaporization chamber to a temperature above the upper temperature limit for vaporization that avoids combustion;
a second conduit of the at least two conduits, the second conduit configured to transport vaporized elements of the compounds out of the vaporization chamber; and
a chopping element internal to the vaporization chamber to break down the cannabis flower into smaller pieces.
