1. A vapor generating apparatus comprising:
- a wick;
a liquid reservoir configured to store a liquid and to supply the liquid to the wick;
a heating coil wound around the wick, the heating coil having a terminal at a first end and being configured to heat liquid on the wick; and
a sensor including at least one rigid resistive wire, the at least one rigid resistive wire having a terminal at a first end and being embedded in the wick such that the at least one rigid resistive wire is arranged at an axis of the heating coil, the sensor configured to detect depletion of the liquid in the liquid reservoir based on an electrical resistance between the terminal at the first end of the heating coil and the terminal at the first end of the at least one rigid resistive wire.

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.
