Description
Technical field
The utility model belongs to electrical heating new cigarette field, is specifically related to a kind of electromagnetic induction that utilizes and carries out the smoking set heated.
Background technology
Along with the public to the reinforcement of cigarette recognizing dangers and government to the increasing of cigarette control dynamics, countries in the world tobacco enterprise strengthens the exploitation to novel tobacco goods.At present, novel tobacco goods mainly comprise the large class of new cigarette, smoke-free tobacco product and electronic cigarette 3.Wherein new cigarette at physiology impression, psychological response, to suck in mode etc. closest to traditional cigarette, there is good development potentiality.
Existing research shows, the most of harmful components in traditional cigarette flue gas are that tobacco produces through the reaction such as thermal cracking, thermal synthesis in high-temp combustion process.Therefore, if temperature when cigarette produces flue gas can be reduced, namely use heating but not the mode of burning tobacco produces flue gas, the reactions such as most ardent solution and thermal synthesis can be reduced, the burst size of overall reduction harmful substances in flue gas.From 1985, luxuriant and rich with fragrance not, Reynolds, the large-scale tobacco enterprise such as Great Britain and America carried out the R&D work of hot type new cigarette in succession, defines 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 " (Accord) that Philips-Philip Morris (Philip Morris USA) develops and " heating " (Heatbar) product that the Fei Mo world (PMI) researches and develops are the representatives of electric heating type tobacco product, and both are formed by special cigarette and electric heater two parts.Fuel hot type cigarette aspect, the thermal source of use comprises burnable solid, liquid or gas, and wherein solid carbonaceous fuel has commercial prod release, and combustible liquid or gas then only have patent to there is no product." Yi Kelaisi " (Eclipse) that " brilliance " (Premier) of RJ Reynolds Tobacco Holdings ,Inc. 1988 listing and nineteen ninety-five go on the market belongs to fuel hot type tobacco product, wherein the latter's modified that is the former.The thermal source that these two 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.
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 the consumption habit of different consumer and is esthetically acceptable to the consumers.
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, in 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), multiple electrically heated cigarette smoking system is described.
But, so far, the test marketing of the luxuriant and rich with fragrance two commercialization electrical heating new cigarette product do not released all does not obtain successfully, this further illustrates electrical heating new cigarette product and is also in early days of growth at present, still there is a lot of problem, 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 the destructive distillation effect of smoking material by its efficiency of heating surface etc., thus remote-effects are to 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 accreditation.
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 the smoking set with new type heater.
