Embodiment Construction

[0067] The electrically heated aerosol-generating system 100 includes an aerosol-generating device having a housing 10 and an aerosol-forming article 20 (eg, a cigarette). The aerosol-forming article 20 comprises an aerosol-forming substrate pushed into the housing 10 into thermal proximity with the heater 30 . The aerosol-forming substrate will release various volatile compounds at different temperatures. By controlling the maximum operating temperature of the electrically operated aerosol generating system 100, the selective release of undesired compounds can be controlled by preventing the release of selected volatile compounds.

[0068] Inside the housing 10 is an electrical power supply 40, for example a rechargeable Li-ion battery. The control circuit 50 is connected to the heater 30 , the power supply 40 , the replacement indicator 60 (such as a light, a display or an audible alarm) and a memory 70 . The control circuit 50 controls the power supplied to the heater 30 ...

Abstract

An aerosol generating device comprising a vaporiser configured to vaporise an aerosol-forming substrate; a battery connected to the vaporiser; a control circuit for controlling the supply of power from the battery to the vaporiser; a memory for storing a usage record of the device; and a replacement indicator for signalling to a user. The control circuit is configured to compare a measured voltage across the battery to a threshold voltage and to generate an error signal to update the usage record if the measured voltage is less than the threshold voltage during an operation cycle. The control circuit is configured to access the usage record and to activate the replacement indicator depending on the status of the usage record.

Description

technical field [0001] The invention relates to an aerosol generating device. In particular, the present invention relates to an aerosol-generating device comprising a vaporizer configured for vaporizing an aerosol-forming substrate of a smoking article. Background technique [0002] There is an increasing need for hand-held aerosol-generating devices capable of delivering an aerosol for inhalation by a user. There is a particular need for a heated smoking device that releases volatile flavor compounds by heating the aerosol-forming substrate without burning the aerosol-forming substrate. The released volatile compounds are delivered to the user in the aerosol. [0003] Any aerosol-generating device that is required to operate by heating an aerosol-forming substrate must contain a heating element. An aerosol-generating device of known type for heating an aerosol-forming substrate in a smoking article by inserting an electric heater into the solid-state aerosol-forming sub...
