Definitions

  • the present invention relates to the technical field of heat-not-burning cigarettes, in particular to an aerosol generating product with a sectional aerosol generating substrate rod.
  • a smoke producing material of particulate heated cigarettes is loose smoke producing particles.
  • the loose smoke producing particles cannot be fixed and must be loaded into an outer tube in a filling mode, and particles on two sides of a smoke producing particle section need to be fixed in a mode of sealing paper and a plugging part, production efficiency is low, and a defective rate is high.
  • the present invention binds the loose smoke producing particles together through an adhesive to form a cylindrical aerosol generating substrate rod. Then, the aerosol generating substrate rod is wrapped with an outer tube, and is then used as a solid aerosol generating substrate rod separately. Then, the solid aerosol generating substrate rod is combined with other elements through a filling, rolling, or composite process to produce an aerosol generating product. Due to the fact that this kind of smoke producing section is already a whole cylindrical aerosol generating substrate rod, there will be no problem of falling and scattering of the smoke producing particles, so there is no need to arrange sealing films or plugging parts on both sides of the smoke producing section. In addition, it is not limited to combine the aerosol generating substrate rod with other elements to produce the aerosol generating product in the filling form.
  • the method of preparing the cylindrical aerosol generating substrate rod by bonding the scattered smoke producing particles with the adhesive is to directly place the scattered tobacco particles in a mixer, add a large amount of adhesives to the mixer, stir and mix evenly, and then extrude and cool.
  • the problems of the aerosol generating substrate rod prepared by this method are: 1, due to the addition of the large amount of adhesives in the stirring process, there is also a cooled adhesive in a gap between the adjacent tobacco particles in the aerosol generating substrate rod after cooling, which leads to low porosity and low axial permeability of the aerosol generating substrate rod; 2, if, in order to avoid the first problem, a small amount of adhesive is added directly in the stirring and mixing process, it will lead to uneven dispersion of the adhesive, and tobacco particles with no glue applied on the surfaces are adjacent, resulting in the inability to bond and the problem of scattering of the smoke producing particles; and 3, another more critical problem is that the addition of the large amount of adhesives may further lead to the application of a large amount of adhesives on the surface of each tobacco particle, seriously affecting the release of aerosol after the tobacco particles are heated. Essentially, the purpose of gluing is only to make scattered tobacco particles bond, but it is not desirable for places where the tobacco particles do not bond to be glued, which affects the aerosol
