Description
Technical field
The invention belongs to electrical heating new cigarette field, be specifically related to a kind of smoking set that utilizes electromagnetic induction to heat.
Background knowledge
Along with public's increasing to cigarette control dynamics to the reinforcement of cigarette recognizing dangers and government, countries in the world tobacco enterprise has been strengthened the exploitation to novel tobacco goods.At present, novel tobacco goods mainly comprise new cigarette, smoke-free tobacco product and the large class of electronics cigarette 3.Wherein new cigarette at physiology impression, psychological response, suck the aspects such as mode and approach traditional cigarette most, there is good development potentiality.
Existing research shows, the most of harmful components in traditional cigarette flue gas are that tobacco produces through reactions such as thermal cracking, thermal synthesis in high-temp combustion process.Therefore,, if the temperature in the time of reducing cigarette and produce flue gas is used heating but not the mode of burning tobacco produces flue gas, can reduce most ardent solution and thermal synthesis etc. and react, the burst size of whole reduction harmful substances in flue gas.Since 1985, luxuriant and rich with fragrance not, the large-scale tobacco enterprise such as Reynolds, Great Britain and America carried out the R&D work of hot type new cigarette in succession, formed three kinds of main hot type new cigarette technology: electrical heating new cigarette, fuel heating new cigarette and chemical heat new cigarette.
Electrical heating new cigarette aspect, " passing through " of Philips-Philip Morris (Philip Morris USA) exploitation (Accord) He Feimo international (PMI) research and development " heating " (Heatbar) product be the representative of electric heating type tobacco product, both are by special cigarette and electric heater two parts formation.Fuel hot type cigarette aspect, the thermal source of use comprises burnable solid, liquid or gas, and wherein the existing commercial prod of solid carbonaceous fuel is released, and combustible liquid or gas only have patent to there is no product." brilliance " of RJ Reynolds Tobacco Holdings ,Inc. 1988 listing (Premier) and " Yi Kelaisi " of nineteen ninety-five listing (Eclipse) belong to fuel hot type tobacco product, the modified that wherein the latter is the former.The thermal source that these two kinds of products are used is carbon solid fuel.Physical and chemical reaction hot type tobacco product, its feature is that the origin of heat that heats tobacco is in physical and chemical reaction, and still, this series products is poor to the control of heat, and technique relative complex not yet realizes commercialization.
Wherein, electrical heating new cigarette has the advantages such as heating-up temperature is controlled, mode of heating is flexible, fashion easy to use, more easily caters to different consumers' consumption habit and is accepted by consumer.
In world wide, Fei Mo company occupy leading position in electrical heating new cigarette field.Fei Mo company (PM) successively develops a generation, two generations electrical heating cigarette smoking system (EHCSS, Electrically Heated Cigarette Smoking System) as brands such as Accord, Heatbar.Meanwhile, aspect electrically heated cigarette smoking system, Philips-Philip Morris discloses multinomial electrical heating new cigarette patent of invention (US6615840, US20070074734, US2007102013, US20110155151, US20050172976, US20040129280, US7690385, US20070256697, US20060070633, US20040261802, US20040200488, US7392809, US7293565, US7234470, US7163015, US6810883, US6026820, US6040560, US5988176, US5967148, US5954979, US5934289, US5915387, US5902501, US5878752, US5750964, US5708258, US5692526, US5692525, US5692291, US5666978, US5666976, US5665262, US5591368, US5530225, US5505214, US5499636, US5498855, US5432882, US5388594, US5372148, US5144962, US5060671), introduced multiple electrically heated cigarette smoking system.
Yet, so far, the test marketing of the luxuriant and rich with fragrance two commercialization electrical heating new cigarette product of not releasing does not all obtain successfully, this further illustrates electrical heating new cigarette product at present also in early days of growth, still there are a lot of problems, be wherein especially embodied in the low and Sensory Quality of Cigarette of electric heater performance and differ from two aspects.And heater can affect by its efficiency of heating surface etc. the destructive distillation effect of smoking material, thereby remote-effects arrive the aesthetic quality of new cigarette.Therefore, electric heater performance is one of central factor affecting the development of electrical heating new cigarette goods and market approval.
At present, traditional following problem of resistance heated electrical heating new cigarette ubiquity: heat utilization rate is low, the response time is long, temperature control is difficult, stability and security is not good enough, service life is short.
Still need to be with the smoking set of new type heater.
