First Claim
Patent Images
1. An electronic vaporizer, comprising:
- a heating element for heating a fluid to produce a vapor;
a power source to provide electrical power to the heating element for heating the fluid; and
a power control circuit configured to regulate a supply of electrical power from the power source to the heating element based at least in part on an operating temperature of the heating element and a temperature setting to prevent the operating temperature of the heating element from exceeding the temperature setting.

17. A power control circuit for an electronic vaporizer having a power source and a heating element, comprising:
-
a current sense configured to measure a current provided to the heating element; a voltage sense configured to measure a voltage applied to the heating element; and a processor-based controller configured to determine an operating temperature of the heating element based at least in part on the current and voltage, and to regulate a supply of electrical power from the power source to prevent the operating temperature of the heating element from exceeding a temperature setting. - View Dependent Claims (18, 19)

20. A method for controlling temperature of a heating element in an electronic vaporizer, comprising:
-
determining an operating temperature of the heating element based at least in part on a measured resistance of the heating element and calibration information established with respect to the heating element; comparing the operating temperature to a temperature setting; and regulating a power supplied to the heating element from a power source to maintain the operating temperature at or below the temperature setting. - View Dependent Claims (21, 22, 23)
