Abstract
The utility model discloses a cigarette prepared with a dual-ventilation technology, belonging to the field of harm reduction and tar reduction of cigarettes. The cigarette is characterized in that tipping paper of a cigarette filter is provided with two separated ventilation hole zones; the difference between the air permeability of the two ventilation hole zones is 100-2000CU; the air permeability of the ventilation hone zone close to a filter end is lower while the air permeability of the ventilation hole zone close to tobacco shred segment is higher; one or more rows of holes are formed in the ventilation hole zones; the distance between the center of the ventilation hole zone closest to the filter end and the filter end is controlled at 8-15 millimeters. Compared with other ventilation filter cigarettes, the cigarette has the advantages that while the total ventilation degree of the cigarette is the same, the tar-oil ratio of carbon monoxide in cigarette smoke is 0.15, and the suction resistance of a dual-ventilation cigarette is about 100-150Pa.
Description
Technical field
The utility model changes the cigarette of traditional flue gas dilution while relating to a kind of suction.
Background technology
Along with the development of smoking and health and the low hazard cigarette of low tar, tobacco enterprise is sought the technology of low-coke tar cigarette one after another, and up to the present cigarette filter aeration technology is a ripe technology that reduces tarry matters in smoke.Cigarette filter ventilates and refers on cigarette tipping paper, there is a plenum area, during suction, from filter tip plenum area, enter portion of air, effectively reduced the suction capacity of burning cone, along with the minimizing of suction capacity, the pipe tobacco amount of burning during suction also just reduces, and flue gas gas phase content and grain phasor also just reduce.
Current most cigarette adopts ventilation dilution Techniques For Reducing tar content in cigarette, but adopts ventilation dilution technology unavoidably to bring aesthetic quality's variation of flue gas, more to the larger material damage of suction quality contribution in flue gas.Adopt its Cigarette Draw Resistance of cigarette of ventilation dilution technology significantly to reduce with ventilation rate increase, when height ventilates, Cigarette Draw Resistance is lower, has the sensation of finding time when people aspirates, and affects cigarette smoking quality.
Utility model content
The purpose of this utility model aims to provide the cigarette of a kind of pair of aeration technology, can effectively increase the resistance to suction of cigarette, keeping cigarette smoking quality simultaneously, effectively reduces the content of cigarette smoke tar, carbon monoxide.
The technical solution of the utility model is:
A kind of cigarette that adopts two aeration technologies, the tipping paper of cigarette filter is provided with two ventilation pore areas that separate, the air permeability of two described ventilation pore areas differs 100-2000CU, wherein low by the air permeability of the ventilation pore area of mouth end, high by the ventilation pore area air permeability of pipe tobacco section; In described ventilation pore area, be provided with single row of holes or many rounds, the width of the ventilation pore area of described single row of holes or many rounds is 5-12mm, by the nearest ventilation pore area center of mouth end and the distance of mouth end, is controlled at 8-15mm.
Between two described ventilation pore area centers, distance is 8-25mm.
Described close mouth end ventilation pore area air permeability is 100-500CU; By the ventilation pore area air permeability 300-2500CU of pipe tobacco section.
In the described air vent region on tipping paper and forming paper, on correspondence position, be adhesive-free area;
In region outside pore area and the forming paper of ventilating on described tipping paper, between correspondence position, be bonding connection.
The technical solution of the utility model compared with prior art has following unexpected technique effect: although first the utility model adopts, be the cigarette of two aeration structures, technical staff originally thinks may further reduce resistance to suction, but adopt after technology of the present utility model, not only can reduce the sensation that low-coke tar cigarette is found time, increase resistance to suction, change flue gas gas grain and balance each other.Different from tradition ventilation dilution is, dilution is elongated, diluted concentration gradient diminishes, effectively reduce the loss of fragrance matter in flue gas, when being conducive to keep cigarette smoking quality, also can effectively reduce harmful constituent in flue gas, as tarry matters in smoke, carbon monoxide, change cigarette smoke carbon monoxide tar ratio.By the utility model scheme, flue gas dilution is divided into two steps, change the process of traditional flue gas dilution, cause flue gas gas granule phase substance ratio to change, bilateral wind pore area cigarette is compared with common single-pass wind pore area cigarette, under identical degree of ventilation, bilateral wind Cigarette Draw Resistance obviously improves 50-150Pa, reduces cigarette smoke carbon monoxide tar ratio and can reach 0.15.
