The invention provides a consumable for a heat-not-burn
aerosol product as well as a preparation method and application of the consumable, and relates to the technical field of tobacco products. The interior of the consumable is hollow to form the
airflow channel, and after the
aerosol generating sheet is heated, the generated
aerosol overflows to the
airflow channel along with the butt seam of each layer of rolling material, so that the overflow of the aerosol and
smoke is more stable, and the suction resistance stability in the suction process is ensured. The
consumables provided by the invention are of a spiral winding structure, and the same
layers of the rolling materials on the same layer do not contact with each other, so that the number of
layers of the cross sections of the
consumables is the same everywhere, the
consumables are uniformly heated everywhere after being heated, aerosol is uniformly overflowed, and the stability of draw resistance is further ensured. And the breadth of the rolling material is calculated through a formula, so that the preparation process of consumables is more efficient, the risk that the edge parts of the same layer are mutually overlapped in the winding process is reduced, meanwhile, the number of winding turns is reduced, and industrial large-scale production is favorably realized.
