Definitions

  • the present disclosure relates to the technical field of low-temperature heat-not-burn products, and particularly relates to an aerosol generating product with a dense segment.
  • the heating temperature for heating a heat-not-burn aerosol generating substrate is usually 250-350°C.
  • heat-not-burn aerosol generating products can greatly reduce harmful substances in the aerosol generating substrate to smokers while reserving the taste of conventional cigarettes, without a high-temperature burning pyrolysis process, so that the release amount of tar and other harmful substances in the aerosol generating substrate is reduced, and thus, the harm of second hand smoking can be greatly reduced.
  • the heating technology for heating the aerosol generating product usually includes resistance heating or magnetic heating.
  • forms of a heating element usually include a tubular heating tube for heating around the aerosol generating product and/or a heating sheet/heating needle inserted into the aerosol generating product for heating.
  • a resistance heating element it heats the aerosol generating product by heat generated by a resistance circuit on the heating element energized.
  • an electromagnetic heating element it generates a current and heat by an induced magnetic field to heat the aerosol generating product.
  • An existing heat-not-burn aerosol generating product usually includes a filter segment through which a user inhales by mouth and an aerosol generating substrate segment away from the filter segment.
  • Air may enter the aerosol generating product from the end surface of the aerosol generating substrate segment and flows out from the end surface of the filter segment.
  • the problem brought about by this is as follows: regardless of heating the aerosol generating substrate with the heating tube or the heating sheet/heating needle, on one hand, when the user does not inhale, there is still a small amount of cold air enters the aerosol generating substrate through the end surface of the aerosol generating substrate segment, a small part of atomized aerosol in the aerosol generating substrate segment encounters the cold air and is condensed to form a liquid, and the liquid flows out from the end surface of the aerosol generating substrate to pollute the device; and on the other hand, when the user inhales, the negative pressure of the aerosol generating substrate segment is low, which makes the aerosol flow to the filter segment, and when the user does not inhale, without the inhaling of the user, under the action of the negative pressure, the small part of aerosol flows from the filter segment to the aerosol generating substrate segment and forms the
  • the present disclosure provides an aerosol generating product with a dense segment, including a dense segment 1, an aerosol generating substrate segment 2, an airway segment 3, and a filter segment 4, .
  • the axial air permeability of the dense segment 1 is 0, that is, the gas is not allowed to pass through axially. It should be noted here that when the dense segment 1 is selected from an airdense material, the axial air permeability of the prepared dense segment 1 is 0. That is, the gas is not allowed to pass through axially, so as to play a role of preventing the gas from entering the aerosol generating substrate segment 2 via the dense segment 1.
  • the density of the dense segment 1 is higher than that of the aerosol generating substrate segment 2, that is, the axial air permeability of the dense segment 1 is less than that of the aerosol generating substrate segment 2, so as to play a role of reducing the gas entering the aerosol generating substrate segment 2 via the dense segment 1.
  • the dense segment 1, the aerosol generating substrate segment 2, the airway segment 3, and the filter segment 4 are segments coiled and formed in the aerosol generating product by a wrapper, or segments filled and formed in the aerosol generating product by being filled into an integrally formed pipe fitting.
  • the dense segment 1 is selected from a non-aerosol-generating material, and is selected from, but is not limited to, a carbon fiber material, a metal membrane, a ceramic or a high molecular material.
  • the high molecular material is selected from, but is not limited to, polyethylene, polypropylene, polyvinyl chloride, polyethylene glycol terephthalate or polylactic acid.
  • the dense segment 1 is selected from an aerosol generating material, the bulk density of the dense segment 1 is higher than that of the aerosol generating substrate segment 2, so as to guarantee that the axial air permeability of the dense segment 1 is less than that of the aerosol generating substrate segment 2. That is, the material of the dense segment 1 is consistent with that of the aerosol generating substrate segment 2 in this case and both the materials are the aerosol generating material. The degrees of compaction at both ends are completely inconsistent.
  • the density of the dense segment 1 is higher than that of the aerosol generating substrate segment 2.
  • the axial air permeability of the dense segment 1 is less than that of the aerosol generating substrate segment 2.

  • an axial position of the side flow hole 32 is close to one end of the aerosol generating substrate segment 2 and is away from one end of the filter segment 4.
  • the reason why the axial position of the side flow hole is closer to one end of the aerosol generating substrate segment 2 is that the closer the axial position of the side flow hole 32 is to the aerosol generating substrate segment 2, the easier it is to extract the aerosol from the aerosol generating substrate segment 2.
  • the number of the side flow holes 32 may be, but is not limited to, 6-8.

  • the inner diameter of the hollow cavity of the first airway segment 33 is less than the inner diameter of the hollow cavity of the second airway segment 34, more aerosols may be gathered in the second airway segment 34, so that the condensation effect on the aerosol is better, the cooling effect on the aerosol is better, and the aerosol is more suitable to inhale.
  • the airway segment 3 is cylindrical and is prepared from, but is not limited to, a cellulose acetate fiber material and a high molecular material.
  • the aerosol generating substrate segment 2 contains the aerosol generating material, and the aerosol generating material is an aerosol generating material in the form of particles or filaments.
  • the forms of the aerosol generating material are only illustrated but are not limited to the above several forms actually, and aerosol generating media capable of generating the aerosol are applicable.
  • the total length of the aerosol generating product in the present disclosure may be 30-80 mm, where the range of the dense segment is 2-10 mm, preferably 5 mm; the length of the aerosol generating substrate segment 2 is 8-25 mm, preferably 12 mm; the length of the airway segment 3 is 10-20 mm, preferably 15 mm; and the length of the filter segment 4 is 8-15 mm, preferably 10 mm.
  • the negative pressure of the aerosol substrate segment will not increase, and thus the aerosol can be prevented from flowing back to the aerosol substrate segment and flowing out from the end surface of the aerosol generating substrate segment when inhaling is stop, so as to further solve the problem that the aerosol condensate flows out from the end surface of the aerosol generating substrate segment to pollute the device.
