Abstract
This electronic cigarette () comprises: —a heating element () able to vapourize a substrate during a smoking period; —means () for measuring an approximation (AUIOMESOO, UIOMESOO) of a characteristic of the voltage (U()) across the terminals of the heating element () during this smoking period, said approximation being measured across the terminals (BB) of a circuit () no component of which exhibits intrinsic characteristics not disturbed by the inhalations; —means () of estimating an approximation (AUTH(t), UIO-m(t)) of said characteristic of the voltage (U()) across the terminals of the heating element () in the absence of inhalation during said smoking period; means () 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 () of estimating the said quantity of substrate vapourized by the heating element at least on the basis of said intensity.
