Description
Technical field
The present invention relates to new cigarette technical field, be specifically related to a kind of Resistant heating device of non-burning cigarette.
Background technology
Traditional cigarette, as the main product form of tobacco consumption, has the history of more than 100 year.Along with transformation, the quick progress of science and technology and the continuous quickening of commodity upgrading speed of people life style and consumption idea, tobacco consumption person's demand and focus constantly change, be subject to the impact of the factors such as tobacco control, public opinion simultaneously, the development of traditional cigarette is restricted, and the appearance of new cigarette has become inevitable.
It is huge that research shows that the cigarette smoke of cigarette burning generation endangers non-smokers, and the hard fire being caused by smoking is to stop.Nicotine and most tobacco aroma component just can be transferred in flue gas at 200-500 degree Celsius, conventional cigarette burning temperature is more than 800 degrees Celsius, if cigarette heating temperature is reduced to below 500 degrees Celsius, the multiple harmful components of flue gas can significantly reduce, and the impact that flavor component is subject to is simultaneously relatively little.Therefore, study a kind of non-burning cigarette of heating smoking apparatus of avoiding pipe tobacco burning to meet again consumer's craving for tobacco demand very meaningful.
At present, the low temperature cigarette that market occurs transmits nicotine and fragrance by the do not burn mode of tobacco of heating to human body, its filling be tobacco material.Low temperature cigarette product has changed traditional cigarette burning and has taked visible smog, adopts the mode of " heating is not burnt ".Correlative study shows, under the lower temperature below 500 ℃, only heats but the tobacco of not burning, and nicotine and Partial Tobacco flavor component just can change and transfer in flue gas.Compared with traditional cigarette, low temperature cigarette can overall significantly reduce the burst size of tar and harmful components.Meanwhile, substantially there is no side-stream smoke, very little to other people, the harm of environment.
At present, gone on the market in the world or the low temperature cigarette researched and developed mainly contains: electrical heating low temperature cigarette, fuel heating low temperature cigarette and chemical heat low temperature cigarette.Electrical heating low temperature cigarette, take electric power as thermal source, heating tobacco material, produces nicotine smog.Fuel heating low temperature cigarette, take extra fuel piece as thermal source, heating tobacco material produces nicotine smog.Chemical heat low temperature cigarette, utilizes chemical reactor to heat as thermal source.
Philip Mirris Products Inc has applied for a kind of smoking article (application number: 89104827.8 applyings date: 1989-07-21), the heat that one of them carbon heat source burning produces passes to spices section, and produce, add cigarette smoke, carbonaceous thermal source and spices section are contained in a cylinder type hollow porcelain bushing not firing.Smoking article does not produce excessive cigarette substantially.The heat that thermal source sends is by convection current and radiation delivery, and this patent adopts carbon rod as heating source, and this mode of heating is disposable, cannot reuse.
Philip Mirris Products Inc has also applied for that a kind of described cigarette of cigarette (application number: 94102530.6 applyings date: 1994-02-25) for the cigarette smoking system at least with an electric heater of tobacco flavor being given to smoker comprises in addition: a carrying pipe, described carrying pipe has longitudinal separated the first and second ends and has the first and second surfaces, first surface crosses a chamber between the first and second ends, and second surface has one to be used for abutting in a region on electric heater; And one deck cigarette Studies of The Aromatic Substances layer, described cigarette Studies of The Aromatic Substances layer is configured on carrying pipe first surface, when being subject to heating, in chamber, produce the tobacco flavor of giving smoker, wherein said carrying pipe and cigarette Studies of The Aromatic Substances layer allow in crossflow inflow chamber, this patent adopts electrically heated mode, not high for the Electric heating efficiency of heating surface.
In addition, for above-mentioned low temperature cigarette, when aspirating, TPM is lower during initial suction, final but it is tending towards progressively improving, the sensation of bringing flue gas intensity to increase gradually to consumer; When heating chamber takes integral type mode of heating to aspirate conventional cigarette, flue gas initial extremely a little less than, then rapidly rise, then, along with the increase of puff number, exhaust gas volumn significantly reduces.This is mainly because it utilizes former mouthfuls of suctions to reach optimum temperature, make tobacco product produce high concentration aerosol, but along with suction process, aerosol produces totally.Compared with conventional cigarette, smoke delivery is uncontrollable, and between different puff numbers, sense organ differs greatly, and sucks the later stage, and organoleptic attribute is tending towards weakening.In addition, heating too early cigarette does not heat position and can cause generating portion smog or this position of cigarette is caused owing to being heated thermic degraded changing self quality; Reheat the position being previously heated and can cause producing offending smell or harmful components.
