A cigarette that changes the traditional smoke dilution process

Abstract

The invention discloses a cigarette which changes the traditional flue gas dilution process, and belongs to the field of harm reduction and tar reduction of cigarettes. The present invention is characterized in that the tipping paper of the cigarette filter is provided with two separated ventilation hole zones, and the air permeability of the two ventilation hole zones differs by 100-2000CU, wherein the ventilation hole zone near the mouth end The air permeability is low, and the air permeability is high in the ventilation hole belt area of ​​the shredded tobacco section; a single row of holes or multiple rows of holes are arranged in the ventilation hole belt area, and the distance between the center of the ventilation hole belt closest to the mouth end and the mouth end is controlled at 8-15mm. Compared with other ventilation filter cigarettes, the present invention can reduce the carbon monoxide tar ratio of cigarette smoke to 0.15 at the maximum when the total ventilation degree of the cigarette is the same, and the double ventilation cigarette has a higher suction resistance of about 100-150Pa.

Description

technical field [0001] The invention relates to a cigarette which changes the traditional flue gas dilution process when smoking. Background technique [0002] With the development of smoking and health and low-tar and low-hazard cigarettes, tobacco companies are looking for low-tar cigarette technology. So far, cigarette filter ventilation technology is a mature technology for reducing smoke tar. Cigarette filter ventilation means that there is a ventilation area on the cigarette tipping paper. When smoking, a part of the air enters from the filter ventilation area, which effectively reduces the suction capacity of the combustion cone. With the reduction of the suction capacity, the The shredded tobacco amount burned during inhalation also decreases, and the gas phase content and particle phase amount of the smoke also decrease. [0003] At present, most cigarettes use ventilation dilution technology to reduce the amount of tar in cigarettes, but the use of ventilation dil...

AI Technical Summary

Problems solved by technology

[0003] At present, most cigarettes use ventilation and dilution technology to reduce the amount of tar in cigarettes, but the use of ventilation and dilution technology will inevitably lead to deterioration of the sensory quality of the smoke, and the loss of substances that contribute greatly to the smoking quality in the smoke is large

Cigarettes that adopt ventilation dilution technology have a significant reduction in cigarette draw resistance as the ventilation rate increases. When the ventilation rate is high, the cigarette draw resistance is low, and people have a feeling of emptying when smoking, which affects the quality of cigarette smoking.
