Heating cigarette filter stick with natural ventilation function and heating cigarette comprising same

Abstract

The invention discloses a heating cigarette filter stick with a natural ventilation function, which sequentially comprises a smoke extraction section (2) and a functional filter stick section (3) from one side close to a fuming section (1) to one side close to a lip end, and forming paper (4) and tipping paper (5) are arranged on the outer sides of the smoke extraction section (2) and the functional filter stick section (3); the smoke extraction section (2) is of a hollow structure and comprises a pipe wall (21) and a pipe cavity (22), the pipe wall (21) does not need to be punched and has a ventilation function, vent holes are formed in the pipe wall (21), and external air can enter the pipe cavity (22) through the vent holes in the pipe wall (21). The pipe wall (21) of the smoke extraction section (2) has a natural ventilation effect, the pipe wall of the cooling section is ventilated by being matched with the forming paper and the tipping paper, external air enters a heated cigarette through pores to be mixed with smoke, and the problem caused by punching the pipe wall of the cooling section is avoided.

Description

technical field [0001] The invention belongs to the field of heated cigarettes, and in particular relates to a heated cigarette filter stick with natural ventilation function 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...

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
