  • Publication number: 20240049782
    Abstract: An aerosol-generating system includes a cigarette and an aerosol-generating apparatus. The cigarette includes a medium part including a tobacco material, a flavor unit including a flavoring material and a moisturizer, and a wrapper configured to wrap the medium part and the flavor unit. The aerosol-generating apparatus includes a first heater arranged on a portion corresponding to the medium part and configured to directly heat the medium part and indirectly heat the flavor unit by using heat transmitted through the wrapper, and a processor configured to control the first heater to make the aerosol-generating apparatus operate in a smoke-free mode in which no visible smoke is generated.

  • Publication number: 20240032587
    Abstract: An aerosol generation device having a smokeless function and an aerosol-generating article used therewith are provided. The aerosol-generating article according to some embodiments of the present disclosure may include a tobacco rod which includes a first filter segment, a second filter segment, and a cavity segment. Here, the cavity segment may be filled with tobacco granules. Since content of moisture and/or content of an aerosol-forming agent in the tobacco granules is lower than that in other types of tobacco materials, generation of visible smoke can be significantly reduced. Also, accordingly, the smokeless function of the aerosol generation device can be easily implemented.

  • Publication number: 20240016218
    Abstract: An aerosol-generating article and an aerosol generation device used therewith are provided. The aerosol generation device according to some embodiments of the present disclosure may include a housing configured to form an accommodation space in which an aerosol-generating article is accommodated and a heater part configured to heat the aerosol-generating article accommodated in the accommodation space, wherein the aerosol-generating article may include a tobacco rod, which includes a cavity segment filled with tobacco granules, and a filter rod. By the heater part having a structure that heats only the cavity segment or heats the tobacco rod from the inside and outside simultaneously, the tobacco granules filled in the cavity segment can be effectively heated.

  • Publication number: 20230292818
    Abstract: A tobacco rod, an aerosol-generating article including the same, and an aerosol generation device used with the aerosol-generating article are provided. The tobacco rod according to some embodiments of the present disclosure may include a first filter segment, a second filter segment, and a cavity segment which is formed by the first filter segment and the second filter segment and filled with a tobacco material. Here, at least one of the first filter segment and the second filter segment may include a paper material that is grease-resistant or water-resistant. Accordingly, a problem that vapor production is decreased due to moisture absorption from components of smoke can be addressed, and a heat-resistant tobacco rod can be manufactured.
