1. A vapor generation device, configured to heat an inhalable material to generate an aerosol for inhalation, comprising: a housing, wherein the housing is internally provided with:
a cavity, configured to receive an inhalable material;
an infrared emitter, comprising an infrared emission material, wherein the infrared emission material is configured to radiate an infrared ray to the inhalable material received in the cavity, so as to heat the inhalable material;
a temperature sensing material, formed on the infrared emitter and insulated from the infrared emission material, wherein the temperature sensing material has a positive or negative resistance-temperature coefficient; and
a circuit, configured to obtain a resistance value of the temperature sensing material and determine a temperature of the infrared emitter from the resistance value.
