Mid-temperature e-cigarette

Abstract

A mid-temperature electronic cigarette that heats ingredients to a temperature range between 125 and 145 degrees Fahrenheit. The temperature range is critical for a consistent cigarette-like taste, aroma, and physiological satisfaction. The ingredients can include tobacco extract, ethyl nicotinate, ethanol, nicotine and ethanol-based flavors, DMEA, but not propylene glycol (PG) or vegetable glycerin (VG). Due to the consistent temperature range, the mid-temperature electronic cigarette can consistently deliver 8-10 μg nicotine per puff, for at least 10 puffs, over 2-8 hours.

1 . A cigarette substitute device comprising:
 a supply reservoir that contains a composition that includes both nicotine and ethanol, but not propylene glycol (PG) or vegetable glycerin (VG); and   a heater configured to heat the composition to a predetermined temperature range between 125-145 degrees Fahrenheit.   
     
     
         2 . The cigarette substitute device of  claim 1 , wherein the predetermined temperature range is 130-140 degrees Fahrenheit. 
     
     
         3 . The cigarette substitute device of  claim 1 , wherein the predetermined temperature range is 134-136 degrees Fahrenheit. 
     
     
         4 . The cigarette substitute device of  claim 1 , wherein the heater stops heating when the composition is above 145 degrees Fahrenheit, and starts heating when the composition is below 125 degrees Fahrenheit. 
     
     
         5 - 6 . (canceled) 
     
     
         7 . The cigarette substitute device of  claim 1 , wherein the composition further comprising ethyl nicotinate. 
     
     
         8 . The cigarette substitute device of  claim 1 , wherein the composition further comprising an ethanol-based flavor. 
     
     
         9 . The cigarette substitute device of  claim 1 , wherein the heater is positioned within the supply reservoir. 
     
     
         10 . (canceled) 
     
     
         11 . The cigarette substitute device of  claim 1 , further comprising a sensor for sensing a temperature inside the supply reservoir. 
     
     
         12 . The cigarette substitute device of  claim 1 , further comprising an air hole. 
     
     
         13 . The cigarette substitute device of  claim 1 , further comprising a microprocessor configured to control heating of the composition. 
     
     
         14 . The cigarette substitute device of  claim 13 , wherein the microprocessor is programed to turn on the heater when temperature inside the reservoir is below 125 degrees Fahrenheit, and to turn off the heater when temperature inside the reservoir is above 145 degrees Fahrenheit. 
     
     
         15 - 18 . (canceled) 
     
     
         19 . A cigarette substitute device having a single supply reservoir, and configured to deliver differing amounts of nicotine as a function of temperature of a composition in the supply reservoir, and an amount breathed in by a user, comprising:
 the composition comprising tobacco extract, ethyl nicotinate, and ethanol, but not propylene glycol (PG) or vegetable glycerin (VG);
 and 
   a heater configured to heat the supply reservoir to a predetermined temperature range between 125-145 degrees Fahrenheit.   
     
     
         20 . (canceled)
