Abstract
A smoking article comprises a smoke generating section, having a tube wall and a tube cavity; the tube cavity being configured to contain the aerosol-forming matrix; an infrared radiation layer, being formed on at least part of the inner surface of the tube wall; the infrared radiation layer being configured to be heated by the smoking set to generate infrared rays and at least heat the aerosol-forming matrix by radiation. The infrared radiation layer is arranged on the inner surface of the tube wall, so that the infrared radiation layer is heated by the smoking set to generate infrared rays and at least heat the aerosol-forming matrix by radiation. The infrared rays have relatively long wavelength, and they can penetrate substance and “resonate” with molecules and atoms inside the substance and produce strong vibration and rotation, so that the temperature of the substance rises to achieve the purpose of heating.
