Abstract: An aerosol-generating device (3) comprises an axially extending heating chamber (15) configured to at least partially receive an aerosol-generating article (5). The aerosol-generating device (3) further comprises a heater actuation mechanism (47) configured to move between an engaging configuration and a non-engaging configuration. The heater actuation mechanism (47) is configured to act on a heater (7) in the engaging configuration to operate the heater (7) to generate heat. The heater actuation mechanism (47) is configured to not act on the heater (7) in the non-engaging configuration to stop generation of the heat by the heater (7). The heater actuation mechanism (47) comprises an operating element (57). The operating element (57) is configured to be moved to move the heater actuation mechanism (47) from the non-engaging configuration into the engaging configuration. The aerosol-generating device (3) further comprises a blocking mechanism (59). The blocking mechanism (59) is configured to temporarily block a movement of the heater actuation mechanism (47) from the engaging configuration into the non-engaging configuration or from the non-engaging configuration into the engaging configuration.

Abstract: An aerosol-forming substrate comprises a first material and a second material, the first material being comprised in the aerosol-forming substrate as a first plurality of discrete elements and the second material being comprised in the aerosol-forming substrate as a second plurality of discrete elements. The first material comprises an aerosol-former and has a first thermal conductivity, and the second material has a second thermal conductivity that is greater than the first thermal conductivity. The presence of the discrete elements of the second material in the aerosol-forming substrate produces a substrate with augmented thermal conductivity resulting in improvements in aerosol generation and delivery.
