Description
Technical field
The present invention relates to the technical field for heating the cigarette that do not burn, the electric heating for more particularly, to heating the cigarette that do not burn is made pottery
Porcelain heater and preparation scheme.
Background technology
Traditional cigarette is still the main product form of tobacco consumption at present, because its mode burnt by heating produces
Flue gas, the temperature of cigarette end can be more than 800 DEG C, and what is discharged in cigarette smoke includes carbon monoxide, tar, amine, phenols, nitrogen
The harmful components such as oxide, nicotine, turn into modern people's focus of attention problem.With concern of the people to health, life
The change of mode and the change of consumption idea, tobacco consumer are badly in need of a novel tobacco product, can have traditional cigarette similar
Experience, but need greatly to reduce influence of the harmful substance to personal, family and society in smoking process.
Heat the cigarette that do not burn under the premise of this to be born, by special cigarette, more low temperature can be used
Heater.Such tobacco product, it is not required to light by naked light, in the case of 300 DEG C of heating are incombustible so that material and perfume (or spice)
Taste is evaporated, and produces similar mouthfeel, but largely avoid the harmful components of 800 DEG C of high temperature above cracking release.Consumption
Person reduces the harmfulness to body while satisfaction obtains.Meanwhile along with the reduction of heating-up temperature, second-hand smog
Amount decrease a lot, it is seen that flue gas it is especially few, it is passive to take in harmful substance species and under intake obtains significantly
Drop.Due to heating these incombustible advantages, in recent years, such as R.J. Reynolds tobacco (R.J. Reynolds) company, Fei Li
Pu Molisi（Philip Morris）Etc. external major company successively be proposed the heating such as IQOS, Eclipse do not burn cigarette production
Product, and applied for domestic and international patent of invention CN101557728A, CN101557728A, CN101778578A, US8851081B2
Deng, it is seen that its attention to the market.
Heating the cigarette that do not burn wants one of successful key to be mode, the stability, uniformity heated.Heating can
Control, stable smog can provide the mouthfeel of similar traditional cigarette, be advantageous to heat the popularization for the cigarette that do not burn.Heat incombustible
Cigarette heating is presently disclosed charcoal heating（CN104585884A）, graphite heating（CN103734910A）, electrical heating
（CN103431525A,CN104585886A）Etc. several ways.Different types of heater is because the heating element heater used differs
Sample, heating effect have very big difference.The heating element heater that heater uses in presently disclosed patent has heating to imitate respectively
Rate is not high, stability is bad, uniformity is inadequate, short life and the shortcomings of without active control smog temperature.Therefore need a kind of new
The heating element heater of type, can be on the premise of stable and uniform heating be provided, on the premise of the life-span for lifting heater, there is provided temperature control
Element, it can be lifted with active control heating-up temperature and absorb experience.
