Cigarette and heater for use in an electrical smoking system

摘要

A cigarette (23) comprises a tobacco rod having filled and unfilled portions arranged so that electrical heater elements (31) may overlap both portions. The tobacco rod includes a tubular tobacco web, which is constructed by converting tobacco feedstock into a continuous sheet of tobacco web into one or more bobbins of tobacco web suitable for automated manufacture of cigarettes. A heater (25) comprises a supporting hub and heater blades (37) defining a receptacle (27) for an inserted cigarette (23). Each blade comprises first and second heater blade arms having first and second end connecting section connecting the second end of the first arm and first end of the second arm. The blades (37) are heated by a resistive heating circuit and heat the inserted cigarette (23). The arms are separated by a gap to permit retracting of flavour substances upon drawing of the cigarette.
