Definitions

the aerosol generation chamber 15 may simply be an interior volume of the housing 2, but the aerosol generation chamber 15 is preferably enclosed by an insulating enclosure within the housing 2, so that additional components such as control circuitry and an electrical power source (not shown) are insulated from heat provided within the aerosol generation chamber 15.
the housing may generally be made from any rigid material such as a thermoplastic or a metal (e.g. aluminium).
the insulating enclosure may be made from a heat-resistant material such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), or polyamide (PA) in order to prevent thermal deformation or melting.
the heat resistant material may be a super engineering plastic such as polyimide (PI), polyphenylenesulfide (PPS) or polyether ether ketone (PEEK).
Aerosol generation device 1 may also comprise securing means 25 which are configured to secure lid 7 with respect to housing 2 when lid 7 is in closed position as can be seen in Fig. 10.
fixing means 25 may be provided as a pair of magnets securing lid 7 to housing 2 while providing haptic feedback to a user of the device.
Figure 9 depicts the embodiment of aerosol generation device 1 with the lid 7 being in between the open and closed position. As can be seen, if only one bolt 14 is provided, only one end of the sliding element is translated towards heating element 10, which means only one edge of the substrate 11 may be pressed towards heating element 10 by means of the bolt. A second edge maybe pressed towards heating element 10 by means of securing means 25 which ensures that the whole surface of substrate 11 is pressed towards heating element 10.
