The vapour flow passage is extendable such that a length between the heater and the mouth end is adjustable.

A vaporiser for an aerosol generating device comprises: a heating element including a sheet of heating material; a tubular heater housing arranged to hold the heating element within the heater housing; and a liquid store . The heater housing comprises a longitudinal gap running along the length of the tubular heater housing, and the heating element is arranged such that a peripheral edge of the heating element is supported within the gap. The gap is arranged to allow a liquid to pass from the liquid store into the heater housing to be vaporised by the heating element during use. The size of the gap is variable to change the rate of liquid flow through the gap , and, in particular, to maintain an optimum liquid flow rate despite a varying viscosity of the vaporisable liquid due to temperature or to differing types of vaporisable liquid being used.
