Devices for vaporization of compounds comprising an oxygen detection mechanism upstream of the vaporization chamber and vaporization device with chopping element internal to the vaporization chamber

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.
