  • the mouthpiece is composed of a dual support structure, that is, the central portions 511 and 712 and the outer portions 521 and 522, thereby preventing the perfume solution from penetrating into the wrapper.
  • the outer portions 521 and 522 are formed of a compressed polymer material having a high packing density. Perfume of 532 can be prevented from penetrating the wrapper surrounding the mouthpiece.

  • the inner diameter of the second support segment 630 has a larger value than the inner diameter of the first support segment 620, such that air passing through the hollow of the first support segment 620 is disposed in the hollow of the second support segment 630. It can be introduced and diffused.
  • the air diffused in the hollow of the second support segment 630 may increase the contact area and the contact time with the outside air introduced through the perforation 631 as the deflection in the downstream direction of the cigarette 600 is reduced. . Accordingly, the cooling effect can be improved.

  • the mouthpiece 640 includes a central portion 641 formed of an incompressible polymer material and an outer portion 642 formed of a compressed polymer material surrounding the central portion, wherein air introduced through the perforation 631 is introduced into the mouthpiece ( As it passes 640, it is concentrated and moved toward the center 641. That is, by concentrating air toward the center portion 641 where the suction resistance is relatively low, it is possible to prevent the migration amount of the aerosol from decreasing.
  • the air introduced from the outside through the perforation 631 may join the air introduced from the tobacco rod 610 end. That is, when the user inhales the cigarette 600, not only the air introduced from the cigarette rod 610 end but also the air introduced through the perforation 631 of the second support segment 630 is delivered to the user, thereby providing the aerosol. You can increase the amount of transition.
