Heating cigarette capable of adjusting air permeability and ventilation position of pipe wall and adjusting method

Abstract

The invention discloses a heating cigarette capable of adjusting the air permeability and the ventilation position of a pipe wall, the heating cigarette comprises a fuming section (1) and a heating cigarette filter stick with a natural air permeability function, the heating cigarette filter stick with the natural air permeability function sequentially comprises a smoke extraction section (2) and a functional filter stick section (3), and the smoke extraction section (2) has the air permeability function; the tipping paper (5) only partially wraps the smoke extraction section (2), only the forming paper (4) is arranged on the outer side of a partial area of one side, close to the fuming section (1), of the smoke extraction section (2), and the tipping paper (5) is not wrapped; the forming paper (4) is breathable, the tipping paper (5) is airtight, and the length and the position of the tipping paper (5) are adjustable. 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 a heated cigarette are adjusted.

Description

technical field [0001] The invention belongs to the field of heating cigarettes, and in particular relates to a heating cigarette and an adjustment method capable of adjusting the air permeability and the ventilation position of the tube wall. 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 redu...

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 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, it can only be drilled somewhere, and then the ambient air will be introduced from where to ventilate and cool down. , the airflow rate which is fixed with the hole size
