Description
Technical field
The invention belongs to novel tobacco technical field, particularly relates to a kind of Novel heating and do not burn cigarette.
Background technique
Burning tobacco is not to be heated by special heating source to pipe tobacco for heating, nicotine when heating in pipe tobacco and
The substances such as fragrance generate flue gas by volatilization to meet a kind of new tobacco products of smoker's demand.Compared with traditional cigarette,
The great change for heating the cigarette that do not burn is in process of consumption that environment temperature locating for tobacco-containing material is lower, usually 300 DEG C
Left and right, and the combustion section temperature of traditional cigarette is up to 900 DEG C or more, the pipe tobacco of cigarette passes through a series of chemistry such as burning, cracking
Thousands of kinds of products can be generated by reacting, and in these products, not only increase the actual bodily harm to consumer, but also to other people or ring
Bring biggish injury in border.
For heating the cigarette that do not burn, consumer is in use, temperature locating for tobacco-containing material is lower than 500 DEG C, and is mainly
Flue gas is generated by the pyrolytic reaction to tobacco-containing material, the probability of poisonous and harmful substance generation can be limited in this way, reduction offsets
The harm of the person of expense and environment.
Existing Cigarette tobacco segment part of not burning of heating is in tobacco substrate mostly by being coated with cigarette at high proportion
Careless extract, adhesive and other feature auxiliary materials are made, but are primarily present following problems:
1, heating Cigarette tobacco segment part consumptive link time from produce to using of not burning is long, easily leads to and heats not
The lost of tobacco extract, adhesive and other feature auxiliary materials, the oxygen being coated at high proportion in burning Cigarette tobacco segment part
Change, is rotten etc..
2, prolonged storage easily lead to heating do not burn tobacco extract that Cigarette tobacco rod is coated at high proportion,
Adhesive and the dip dyeing of other feature auxiliary materials, influence appearance.
3, finished product tobacco segment part generally keeps higher moisture content, and tobacco segment part adds by high temperature in aspiration procedure
Heat, release first be high-temperature vapor and minimal amount of coating tobacco extract and other characteristic body volatile matters
Matter causes drawing smoke temperature excessively high and insipid.
Summary of the invention
It does not burn cigarette the object of the present invention is to provide a kind of Novel heating, it is broken to solve capsule existing in the prior art
The problem of flue gas caused by splitting loses, just suction sensory effects are bad and impregnate to cigarette paper.
The present invention is achieved by the following technical solutions:
A kind of Novel heating does not burn cigarette, including fillter section and bringing-up section；The fillter section is connect with the bringing-up section
It is structure as a whole；
The bringing-up section includes the cigarette paper layer of tobacco section and outer layer；
The tobacco section is by load matrix and is adsorbed in the intracorporal tobacco microcapsules of load base and forms.
The outer surface of the tobacco section is provided with protective film layer.
The load matrix is cylindrical structure.
The load matrix is tobacco, porous support materials or the gas permeable material containing cavity.
The porous support materials refer to the incombustible porous material of heating.
The porous support materials include one or more of zeolite, diatomite, activated carbon, porous silicate
Combination.
The porous silicate refers to the doughnut of cupric silicate or silicic acid nickel.
The partial size of the tobacco microcapsules is less than 300 μm.
The core material of the tobacco microcapsules includes tobacco extract, tobacco extract, pure tobacco oil, essential oil of tobaccos or tobacco wind
One of taste essence or multiple combinations and smoke agent.
The wall material of the tobacco microcapsules includes natural macromolecular material, semi-synthetic high molecular material or fully synthetic macromolecule
Material.
The beneficial effects of the present invention are:
The technical program is set as by that will heat cigarette tobacco segment part of not burning using load matrix and load tobacco
Load is had the microcapsules of tobacco extract or other property materials to be carried on load matrix, passes through height compared to tradition by microcapsules
Ratio coating tobacco extract, adhesive and other feature auxiliary materials are made, and finished product tobacco rod can obviously reduce its moisture content, keep away
Exempt from scattering and disappearing and contact caused oxidation deterioration, and the leaching to cigarette paper layer with air for tobacco extract and other property materials
Stain has improved the flue gas mass stability that consumer just inhales, and improves sensory effects.
The technical solution of the application is that can satisfy the cigarette of radial heating smoking set.
