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.

A vaporizer may include a battery portion, a cartomizer connectable with the battery portion, and a sleeve fitable over the cartomizer. The sleeve and an outer shell of the battery portion may have the same or complimentary colors or patterns. The battery portion may further include a plurality of illuminable indicators, which may illuminate to indicate, for instance, remaining voltage of a battery housed within the battery portion.

This electronic cigarette (1) comprises: —a heating element (10) able to vapourize a substrate during a smoking period; —means (30) for measuring an approximation (AUIOMESOO, UIOMESOO) of a characteristic of the voltage (U10(t)) across the terminals of the heating element (10) during this smoking period, said approximation being measured across the terminals (BI, B2) of a circuit (500) no component of which exhibits intrinsic characteristics not disturbed by the inhalations; —means (30) of estimating an approximation (AU10TH(t), UIO-m(t)) of said characteristic of the voltage (U10(t)) across the terminals of the heating element (10) in the absence of inhalation during said smoking period; means (30) of calculating an intensity (F) representative of the intensity of the inhalations during said smoking period on the basis of an integration of the difference between said approximations during said smoking period; and —means (30) of estimating the said quantity of substrate vapourized by the heating element at least on the basis of said intensity.
