  • the filter part may further include a mouthpiece filter at the rear side of the cooling filter.
  • the present invention provides a device for generating aerosol including the article for generating aerosol.
  • the article for generating aerosol of the present invention includes a cooling filter having a cavity structure filled with a particulate coolant therein to increase a contact with the aerosol, thereby securing an improved cooling effect.
  • the article for generating aerosol of the present invention further includes a tube filter which is disposed in front of the cooling filter and has a hollow hole having a size at which the particulate coolant does not pass, thereby improving filtration performance for foreign substances and pyrolysis components in an aerosol flow.
  • the aerosol generated from the article for generating aerosol of the present invention is excellent in quality, thereby improving the user's satisfaction with smoking and increasing productivity and economics in terms of process and cost.
  • front and rear used in the present invention are defined based on an aerosol flow.
  • FIG. 1 is a diagram illustrating an embodiment of an article for generating aerosol (or a heating-type cigarette) according to the present invention.
  • an article for generating aerosol 3 of the present invention includes a medium part 310 and a filter part 320.
  • the medium part 310 and the filter part 320 have cylindrical shapes and the same outer diameters to have an integrated shape in which the medium part 310 and the filter part 320 are connected to each other.
  • the filter part 320 may include a tube filter 321, a cooling filter 322 and a mouthpiece filter 323.
  • the article for generating aerosol 3 illustrated in FIG. 1 is only an embodiment, and some components may be omitted.
  • the article for generating aerosol 3 at least one of the tube filter 321, the cooling filter 322 and the mouthpiece filter 323 may not be included.

  • the aerosol generating material may include at least one selected from the group consisting of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and oleyl alcohol.
  • the length of the medium part 310 may be about 12 mm, but is not limited thereto.

  • the medium part 310 may be filled with tobacco cut fillers.
  • the tobacco cut fillers may be generated by finely crushing a tobacco sheet.
  • a process for allowing the tobacco sheet to be easily folded is additionally required. Accordingly, compared to filling the medium part 310 with the tobacco sheet, it is easier to fill the medium part with the tobacco cut fillers, and productivity and efficiency of the process for producing the medium part 310 may be further increased.
  • the medium part 310 may be filled with a plurality of tobacco strands in which the tobacco sheet is finely cut.

  • One tobacco strand may be formed in a cuboid shape having a horizontal length of 1 mm, a vertical length of 12 mm, and a thickness (height) of 0.1 mm, but is not limited thereto.
  • the medium part 310 filled with the tobacco strands may generate a larger amount of aerosol. If the tobacco sheet or the tobacco strands are filled in the same space, compared to the tobacco sheet, the tobacco strands ensure a larger surface area. The large surface area means that there is more opportunity for the aerosol generating material to contact external air. Accordingly, when the medium part 310 is filled with the tobacco strands, a larger amount of aerosol may be generated than the medium part filled with the tobacco sheet.
  • the medium part 310 filled with the tobacco strands may be more easily separated than the medium part filled with the tobacco sheet.
  • a frictional force generated when the tobacco strands are in contact with a heater for heating is smaller. Accordingly, when the medium part 310 is filled with the tobacco strands, the medium part may be more easily separated from the holder than the medium part filled with the tobacco sheet.
  • the tobacco sheet may be formed by crushing the tobacco raw material in a slurry form and then drying the slurry. For example, 15% to 30% of an aerosol generating material may be added to the slurry.

  • the cross section of the inner hollow hole of the tube filter 321 is formed in a polygonal shape other than the circular shape to prevent the tobacco cut fillers included in the medium part 310 from being introduced and increase a surface area in contact with the aerosol to cool a hot aerosol generated from the medium part 310, thereby improving a cooling effect of the aerosol.
  • the tube filter 321 includes one hollow hole therein, and the hollow hole may be a shape of forming 3 to 8 straight channels extending toward an outer circumferential surface of the tube filter 321 from a central axis of the tube filter 321.

Further, the tube filter may have a circumferential ratio of the outside of the tube filter and the inside of the hollow hole of from 1:0.60 to 1:0.90, preferably from 1:0.70 to 1:0.85.
  • the cross-sectional area ratio and the circumferential ratio of the outside of the tube and the inside of the hollow hole of the tube filter are associated with the volume and the surface area of the hollow hole, and when the cross-sectional area ratio and the circumferential ratio are less than the above ranges, a passage in the tube filter 321 is narrowed so that the aerosol flow generated from the medium part 310 may be reduced. On the contrary, when the cross-sectional area ratio and the circumferential ratio exceed the above ranges, the passage in the tube filter 321 is increased so that a desired effect cannot be obtained.
  • the length of the tube filter 321 may be from 7 to 15 mm, preferably from 7 to 10 mm.
  • the length of the tube filter 321 may be shorter than about 7 mm, but may have a length that does not impair a function of at least one filter part element (e.g. a cooling filter, a capsule, a mouthpiece filter, etc.).

  • a combustion-type or non-combustion type (heating-type) cigarette For example, an aerosol generated in the combustion-type or non-combustion type (heating-type) cigarette is cooled by external air to generate liquid substances (e.g. moisture, etc.).
  • the smoke is generated by combusting at a high temperature of 800 °C or higher, the smoke is dry without moisture, so that a perceived temperature of the mainstream smoke felt by smokers is also not high.
  • the moisture content in the smoke is relatively high by vaporizing the aerosol generating material at a low temperature of about 200 °C. Accordingly, the perceived temperature of the mainstream smoke is high, which may be a factor that degrades the smoker's feeling of use. Therefore, in the case of the article for generating aerosol, a role of the cooling filter is very important for improving the quality and the feeling of use of the aerosol.
