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 rod includes a tubular tobacco web. The web is constructed by converting tobacco feedstock into a continuous sheet of tobacco web and converting the continuous sheet of tobacco web into one or ore bobbins of tobacco web suitable for automated manufacture of cigarettes. A heater (25) comprises a supporting hub and electrically resistive heater blades (37) defining a receptacle (27) for an inserted cigarette (23). Each blade comprises first and second heater blade legs each having a first end and a second end, and a connecting section connecting the second end of the first leg and the first end of the second leg. The blades (37) are heated by a resistive heating circuit and heat the inserted cigarette (23). The legs are separated by a gap to permit entrainment of flavour substances upon drawing.
