Abstract
A heat insulation mechanism suitable for an electromagnetic induction-type aerosol generation device and an aerosol generation device are provided. The aerosol generation device comprises a magnetic field generator and a susceptor that are inductively coupled; a heat insulator configured to reduce conduction of heat from the susceptor to the outside, the heat insulator comprising a tube wall, and a central region defined by the tube wall, the tube wall containing a metal or an alloy, and the pressure in the central region being configured to be lower than the pressure outside the heat insulator; and a magnetic field shield, configured to isolate the heat insulator from a varying magnetic field, so as to prevent the heat insulator from being penetrated by the varying magnetic field to generate heat. The aerosol generation device can shield the vacuum heat insulator from the magnetic field as far as possible.
