Title
(EN) APPARATUS FOR HEATING SMOKABLE MATERIAL
(FR) APPAREIL POUR LE CHAUFFAGE D'UN MATERIAU DESTINE A ETRE FUME
Abstract
(EN)

An apparatus (1) arranged to heat smokable material to
volatilise at least one component of said smokable material. The apparatus
comprises: a housing (9); the housing (9) having a first opening
(20 at a first end (3) through which a consumable article (21) containing
smokable material can be removably inserted into the apparatus; at
least one heater arrangement (23) arranged within the housing (9) for
heating smokable material within the consumable article (21) when in
use and a hollow chamber (35) between the first opening (20) and the
at least one heater (23). The hollow chamber (35) surrounds at least a
portion of the consumable article (21) when the consumable article is
inserted into the device and an inner wall of the chamber and the at least
a portion of the consumable article define an air gap (36) there between.
Hot vapours that escape the consumable article in use can condense on
the inner wall of the chamber.
