Abstract
A flavored vapor generator (100, 200, 300, 400) used for an electronic smoking apparatus (10) comprises a housing; a liquid retention material (155, 255) which is filled, soaked or immersed with a flavored liquid and received inside the housing; an electric heater (150, 350, 450) for heating the liquid retention material (155, 255) to generate flavored vapor; and a sensor (156, 356, 456) for monitoring soaking or wetness conditions of the liquid retention material (155, 255) and providing signals for determining whether the flavored liquid in the liquid retention material (155, 255) is exhausted or almost exhausted.
Claims18
An electronic smoking apparatus comprising:
- a liquid reservoir configured to store a liquid;
- an electric heater configured to heat the liquid of the liquid reservoir to generate a vapor;
- a wick configured to draw liquid from the liquid reservoir, wherein a sensor is wound around the wick;
- and
- an electronic controller connected to ends of the sensor through respective first terminals, the electronic controller configured to
- measure an electrical resistance using the sensor, and
- detect depletion of the liquid in the liquid reservoir based on the electrical resistance of the sensor.
