Abstract
An electronic smoking device comprises a housing accommodating a battery as an electric power source powering an electrically heatable atomizer comprising an electric heater and adapted to atomize a liquid supplied from a reservoir to provide an aerosol exiting from the atomizer. The heater of the atomizer is controlled by means of control electronics. A puff detector indicates an aerosol inhaling puff to the control electronics. The control electronics operates, for a puff, the heater of the atomizer with a predetermined level of electric power. Preferably, the electronic smoking device comprises a voltage sensor measuring the battery voltage, wherein the control electronics distributes the predetermined level of electric power, for a puff, by pulse width modulation, based on the battery voltage measured by the voltage sensor.
