Abstract (en)
An aerosol generation device (1) comprises:- a reservoir (5) storing an aerosol-forming liquid,- a heater (18) arranged, when supplied with electrical power, for heating this aerosol-forming liquid to induce generation of an aerosol that can be inhaled by a user during a puff, and- an electrical and control device comprising a controller arranged for controlling electrical power supply to this heater (18) and, after each puff, for estimating a first quantity of aerosol-forming liquid consumed from at least an electrical power supplied to the heater (18), a puff duration and a flow rate of the generated aerosol, and a second quantity remaining in the reservoir (5) by subtracting the estimated first quantity from the last second quantity remaining before the puff, and for triggering an alert for the user when this estimated second quantity is smaller than a chosen threshold.
