AEROSOL-GENERATING ARTICLE WITH DOWNSTREAM SECTION HAVING LOW RESISTANCE TO DRAW Russian patent published in 2025 - IPC A24D1/20 A24F40/20 

FIELD: smoking accessories.

SUBSTANCE: group of inventions relates to the tobacco industry, in particular to devices simulating the tobacco smoking process. Aerosol-generating article (10) comprises a rod of aerosol-generating substrate (12). Aerosol-generating substrate contains one or more aerosol-forming substances. Content of the aerosol-forming substance in the aerosol-forming substrate ranges from 10 percent to 20 percent by weight in terms of dry weight. Aerosol-generating article comprises mouthpiece (50) located downstream of the aerosol-generating substrate rod. Mouthpiece element contains at least one mouthpiece filtering segment made of fibrous filtering material. Tightening resistance of the mouthpiece filtering segment ranges from 4 mm  of H₂O to 11 mm of H₂O. Aerosol-generating article comprises hollow tubular element (20). Hollow tubular element is provided between rod of aerosol-generating substrate and mouthpiece element. Total length of the hollow tubular element and the mouthpiece is from 24 mm to 32 mm. Aerosol-generating system (100) comprises the claimed aerosol-generating article (10) and aerosol-generating device (1) comprising a heating chamber for accommodating the aerosol-generating article and at least a heating element provided in the heating chamber or around its periphery.

EFFECT: increased phase of useful cooling and aerosol nucleation, as well as providing low variability of resistance to draw.
