Aerosol generation apparatus

An aerosol generation apparatus, for heating a smokable material to generate an aerosol for smoking, comprising a housing, wherein a heat insulation cylinder comprising an open end and a closed end is disposed in the housing;

• the heat insulation cylinder is internally provided with:
• a bracket, configured as a tubular shape extending along an axial direction of the heat insulation cylinder, at least a part of a tubular hollow of the bracket forming a cavity, and the smokable material being capable of being at least partially received within or removed from the cavity through the open end;
• a heater, configured as a pin or blade shape at least partially extending along the axial direction of the cavity;
• a first air medium layer, surrounding the cavity due to that a certain interval is kept between the bracket and the heat insulation cylinder, the first air medium layer being configured to reduce outward conduction of heat generated by the heater along a radial direction;
• and
• an airflow channel, comprising a first portion extending at least partially within the first air medium layer from the closed end to the open end, and a second portion extending within the cavity from the open end to the closed end.
