Abstract
Thermal cleaning of an electrically heated smoking device, and in particular the removal of condensates formed within the smoking device as a result of extended periods of use, is achieved with a cleaning system that utilizes inductive heating that provides efficient and intense localized heating in the cleaning process. The thermal power of the inductive heating process is increased or the power necessary to activate the inductive heating process is decreased by the addition of a magnetic shell by itself or in combination with a magnetic pin.
