Abstract

This application relates to the field of cigarette devices, and provides an aerosol generation device and an infrared heater. The aerosol generation device includes a chamber, configured to receive an aerosol forming substrate; and at least one infrared heater, including a plurality of carbon material heating tubes, where the plurality of carbon material heating tubes are constructed to heat the aerosol forming substrate received in the chamber in an infrared radiation manner. In this application, a plurality of carbon material heating tubes heat an aerosol forming substrate received in a chamber in an infrared radiation manner. Because infrared has a strong penetrability, temperatures inside and outside a cigarette may be distributed more evenly, a heating speed is higher, and fragrance is released more fully, thereby improving inhaling experience of a user.
