Description
Technical field
The utility model belongs to and heats not burning type cigarette filter tip technical field, is specifically related to a kind of NEW TYPE OF COMPOSITE mouth rod for heating not burning type cigarette.
Background technology
Heat not burning type cigarette, its heating-up temperature is less than 500 DEG C usually.Research shows, smoke of tobacco harmful components burst size and heating, ignition temperature are closely related, reduces heating or ignition temperature can significantly reduce harmful ingredients in flue gas burst size.While meeting the impression of consumer tobacco feature, reducing harmful ingredients in flue gas burst size, reduce the harm to consumer, is the starting point of the heating not burning type Cigarette design research and development with " heat tobacco but not burning tobacco " feature.Based on this, compare the novel tobacco goods of other type such as smokeless tobacco and electronic cigarette, heat not burning type cigarette at physiology impression, psychological response, suck in mode etc. closest to traditional cigarette, there is obvious harm reduction feature simultaneously, as produced " second-hand-cigarette " hardly, visible main flume is considerably less, and the harmful substance kind that smoker takes in and intake significantly decline, and have good development potentiality.
Heat not burning type cigarette technological development and start from 1985, at present, defined three kinds of main heating not burning type cigarette technology: electric heating type do not burn cigarette and the chemical heat type of cigarette, fuel hot type that do not burn or not cigarette.
In view of the unique advantage heating not burning type cigarette, Philip Mirris Products Inc's (being called for short phenanthrene not), R.J. Rainolds Tobacco CO.'s (abbreviation Reynolds), British-American Tobacco Company Limited's (being called for short Great Britain and America) etc. have carried out system research for heating not burning type cigarette correlation technique, have especially carried out intellectual property layout for heating not burning type Cigarette.Chinese patent CN96194107.3, CN201190000997.0, CN201280018570.2, CN201280026033.2, CN201280054623.6, CN201280048973.1, CN201280054563.8, CN201180016009.6, CN101778578 A, CN 103889254 A of Fei Mo tobacco company application, Chinese patent CN201180031721.3, CN200780045783.3 of Reynolds Tobacco Company's application disclose the cigarette technology heating not burning type cigarette.
From heating the not exploitation of burning type cigarette product and marketing, do not burn cigarette and fuel hot type of electric heating type does not burn the listing of cigarette existing procucts.Wherein, " heating " (Heatbar) that " passing through " (Accord) of Philips-Philip Morris (Philip Morris USA) successively exploitation and the Fei Mo world (PMI) research and develop and IQOS are that electric heating type does not burn the representative of cigarette, and three is by special cigarette and electric heater two parts formation.Fuel hot type does not burn cigarette aspect, the thermal source used comprises burnable solid, liquid or gas, at present, the three generation products that RJ Reynolds Tobacco Holdings ,Inc. successively releases all adopts solid carbonaceous fuel: " brilliance " (Premier) of listing in 1988, " Yi Kelaisi " (Eclipse) of nineteen ninety-five listing and the REVO by listing in 2015, the thermal source that these three kinds of products use is carbon solid fuel.Physical and chemical reaction hot type tobacco product, its feature is that the origin of heat of heat tobacco is in physical and chemical reaction, but the control of this series products to heat is poor, and technique relative complex, not yet realizes commercialization.
But, so far, the do not burn test marketing of cigarette product (Accord, HeatBar) of the luxuriant and rich with fragrance front two commercialization electric heating type do not released all does not obtain successfully, this further illustrates the electric heating type cigarette product that do not burn and is also in early days of growth at present, still there is a lot of problem, wherein especially the problem of core be electric heating type do not burn cigarette suction impression poor, limit its marketing to a certain extent, it is embodied in: flue-gas temperature is high, flue gas suction homogeneity is poor, response time length, amount of smoke relative deficiency etc.
And cigarette directly affect electric heating type do not burn cigarette suction impression, therefore, for the problems referred to above, carrying out cigarette structure innovation will have important practical significance.
For the problems referred to above, the utility model provides a kind of composite tip stick of the novel cigarette that do not burn for electric heating type.
