  • the method of online laser drilling is often used to perforate in the hollow support segment of the heating cigarette, and the pipe wall of the hollow support segment as well as the shaping paper and tipping paper wrapping the hollow support segment are perforated to form ventilation pores and introduce air; however, this method still has the following problems: 1.
  • the process of online laser drilling has higher requirements on the pipe-wall material and thickness of the hollow support segment, the material of the hollow support segment pipe wall can neither collapse during the process, nor be too thick to perforate during the process; 2.
  • ventilation pores are formed by punching through the hollow support segment as well as the shaping paper and tipping paper wrapping the hollow support segment, outside air directly enters the hollow support segment through the ventilation pores, quick air introduction of ventilation pores, limited contact area between the introduced air and the snoke, and uneven mixing may result in an increase in the amount of smoke inhaled into the consumer's mouth, while smoke concentration is low as it is obviously mixed with a large amount of air, so that smoking quality is seriously affected.
  • problems of using physical perforation method to make the wall of heating cigarette pipe ventilate include nonadjustable permeability volume and fixed permeability position; as introduction of air through physical perforation only lies in where to perforate and where to introduce ambient air for ventilation and cooling, permeability rate is fixed with the size of the hole.
  • permeability rate is fixed with the size of the hole.

  • the heating cigarette with adjustable pipe-wall air permeability and permeation position includes a smoking segment 1 and a heating cigarette filter rod with natural permeability function, the smoking segment and the heating cigarette filter rod are assembled and molded by a shaping paper 4; a tipping paper 5 wraps around at least part of the outer side of the shaping paper 4 wrapping the heating cigarette filter rod with natural permeability function;
  • the smoke extraction segment 2 has a hollow structure, including a pipe wall 21 and a pipe cavity 22.
  • the pipe wall 21 does not need to be perforated due to its permeability function, there are ventilation pores disposed inside the pipe wall 21, outside air can enter the pipe cavity 22 through the ventilation pores inside the pipe wall 21.
  • the cross-segmental area of the pipe cavity 22 is not limited to a circle, which can also be of any shape such as a triangle, a polygon, or a pentagram.
  • the tipping paper 5 covers 1/6-5/6 of the axial length of the smoke extraction segment 2.
  • air permeability of the shaping paper 4 is 1000-10000CU.
  • the pipe wall 21 is molded by particles adhesion and extrusion, and the voids among the particles after molding are used as the ventilation pores, the pipe wall 21 itself has a permeability function;
