Intermediate breathable ternary composite filter stick and heating cigarette comprising same

Abstract

The invention discloses an intermediate breathable ternary composite filter stick and a heating cigarette comprising the same, from a far lip end to a near lip end, the intermediate breathable ternary composite filter stick comprises a support blocking section (6), a smoke extraction section (2) and a functional filter stick section (3); the supporting blocking section (6) and the functional filter stick section (3) do not have a ventilation function; the smoke extraction section (2) has a ventilation function; tipping paper (5) only partially wraps the smoke extraction section (2), the forming paper (4) is breathable, and the tipping paper (5) is airtight. According to the invention, the smoke extraction section (2) separated from the fuming section serves as the ventilation section for the first time, and after the heating cigarette is inserted into the cigarette, the cooling effect and the smoke amount are better. Meanwhile, according to the cigarette heating structure, the air permeability and the air permeability position of the smoke extraction section (2) can be adjusted by adjusting the size and the position of the area, covering the smoke extraction section (2), of the tipping paper (5), and therefore the air permeability and the air permeability position of the heated cigarette are adjusted.

Description

technical field [0001] The invention belongs to the field of heated cigarettes, and in particular relates to a middle air-permeable ternary composite filter rod and a heated cigarette containing the same. Background technique [0002] As consumers pay more attention to health issues and demand for personalized experience of cigarette products, the tobacco industry continues to respond to the upgrading of consumer demand and develops various heated cigarettes with reduced tar and harm. Among them, heat-not-burn cigarettes can provide a healthier smoking experience while satisfying consumers' sensory needs for cigarette products because their cigarettes are heated in a different way than traditional cigarette products. [0003] Existing heated cigarettes mainly include a smoking core section, a hollow support section, a cooling section, and a filtering section. In order to introduce air, increase the ventilation rate, and effectively reduce the temperature of the smoke, the he...

AI Technical Summary

Problems solved by technology

[0003] Existing heated cigarettes mainly include a smoking core section, a hollow support section, a cooling section, and a filtering section. In order to introduce air, increase the ventilation rate, and effectively reduce the temperature of the smoke, the heated cigarette usually adopts an online laser drilling method to heat the cigarette. The hollow support section punches through the hollow support section tube wall and the molding paper and tipping paper wrapping the hollow support section to form ventilation holes and introduce air, but the method still has the following problems: 1. The process of online laser drilling There are high requirements on the material and thickness of the tube wall of the hollow support section. First of all, the material of the tube wall of the hollow support section cannot collapse during the online laser drilling process, and the tube wall of the hollow support section should not be particularly thick, so as to avoid the online laser drilling. 2. The online laser drilling process has high requirements on laser power. If the laser drilling equipment fails to penetrate the tube wall of the hollow support section, the production of heated cigarettes will be unqualified and the smoke temperature will be overheated. 3. At present, ventilation holes are formed by piercing through the hollow support section and the forming paper and tipping paper wrapped around the hollow support section. The outside air directly enters the interior of the hollow support section through the ventilation hole. The contact area between the air and the smoke is limited and the mixing is uneven, resulting in an increase in the amount of smoke inhaled into the consumer's mouth, but the smoke concentration is low, the smoke is obviously mixed with a large amount of air, and the quality of smoking is seriously reduced

[0004] In addition, the existing heated cigarettes usually perforate the outer wall of the support section adjacent to the smoking section so that the hot smoke and air can be mixed most directly. The vent hole is also located deep in the cigarette holder chamber of the smoking appliance, and the heated cigarette is in close contact with the inner wall of the cigarette holder chamber, which makes the amount of air introduced by the vent hole very small, which has the effect of cooling the smoke and increasing the amount of smoke not obvious

[0005] In addition, the use of physical drilling to ventilate the heated cigarette tube wall still has the problem of non-adjustable ventilation volume and fixed ventilation position. Due to the introduction of air through physical drilling, the only way to punch holes is to introduce ambient air from there. Perform ventilation and cooling, and the ventilation rate is fixed with the size of the hole
