Abstract
An aerosol-generating device for use in an aerosol-generating system is provided, the aerosol-generating device including a cavity configured to receive an aerosol-generating article; a heat exchanger having a first portion proximate to the cavity and a second portion distal to the cavity for capturing heat from a lighter; and a retractable cover, wherein the retractable cover is movable from a first position in which the retractable cover covers the second portion of the heat-exchanger to a second position in which the second portion of the heat exchanger is exposed for heating by a lighter and wherein the retractable cover is configured to automatically return from the second position to the first position when the second portion of the heat exchanger reaches a threshold temperature.
