niman Posted September 30, 2019 Author Report Share Posted September 30, 2019 (edited) United States Patent 9,549,573 Monsees , et al. January 24, 2017 Vaporization device systems and methods Abstract Vaporization devices and methods of operating them. In particular, described herein are methods for controlling the power applied to a resistive heater of a vaporization device by measuring the resistance of the resistive heater at discrete intervals. Changes in the resistance during heating may be used to control the power applied to heat the resistive heater during operation. Also described herein are vaporization devices that are configured to measure the resistance of the resistive heater during heating and to control the application of power to the resistive heater based on the resistance values.

niman Posted September 30, 2019 Author Report Share Posted September 30, 2019 (edited) In preferred embodiments, the tobacco or botanical is heated to about 300.degree. C. at most. In other preferred embodiments, the tobacco or botanical is heated to about 200.degree. C. at most. In still other preferred embodiments, the tobacco or botanical is heated to about 160.degree. C. at most. It should be noted that in these lower temperature ranges (<300.degree. C.), pyrolysis of tobacco or botanical does not typically occur, yet vapor formation of the tobacco or botanical components and flavoring products does occur. In addition, vapor formation of the components of the humectant, mixed at various ratios will also occur, resulting in nearly complete vaporization, depending on the temperature, since propylene glycol has a boiling point of about 180.degree.-190.degree. C. and vegetable glycerin will boil at approximately 280.degree.-290.degree. C. http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=23&f=G&l=50&co1=AND&d=PTXT&s1=monsees.INNM.&s2=bowen.INNM.&OS=IN/monsees+AND+IN/bowen&RS=IN/monsees+AND+IN/bowen Edited October 22, 2019 by niman 1 Link to comment Share on other sites More sharing options...
