2000000000 dollars, amplification is up to 691%.The research also shows：Japan, which is that the current whole world is maximum, heats the tobacco product that do not burn
The 96% of such product global marketing amount is occupied in market；Germany is second largest market, and the U.S. will be more than Germany in 2021；The
Three and the fourth-largest market be Switzerland and Portugal respectively, the two countries are also fastest-rising markets.Based on this, the whole world is large-scale
Tobacco enterprise starts volume increase one after another and is not necessarily to the heating lighted not burner and its heating rod.In fact, production IQOS (overstate by love
Think) the Philips Mo Lisi tobacco international corporation of burner has not put into a huge sum of money for 2017 and has built in German east for heating
If new factory, not burner and its matched heating rod also heat in Italy, Switzerland and Greece's production in the said firm.British American Tobacco
Company is proposed similar products GLO- lattice Shandong on Korean market, and international corporation of Japan Tobacco is home proposed heating in the market

Tobacco aroma is discharged under the premise of burning, and smoker can be made to reduce while obtaining satisfaction and actively and passively smoked to human body
Harmfulness.
The flue gas that traditional cigarette burning generates cools down mainly by rear end pipe tobacco and filter stick filter process, to reach
Temperature is sucked to what human body was suitable for.It heats the cigarette that do not burn to carry out in the heating device that baking temperature is 200-400 DEG C, generate
Flue gas cooling processing need to be also carried out in mouthpiece filter segment, reach the temperature of human body appropriate contact, while meeting smoker to cigarette
The requirement of port sense.In order to fully ensure that effective rate of utilization that low-temperature heat tobacco smoke is sucked by human body, need as far as possible
The flue gas adsorption rate of fillter section is reduced, i.e. fillter section should can cool down and adsorb less as far as possible again.
Philips Mo Lisi tobacco international corporation exploitation low temperature not burning cigarette IQOS include tobacco product section, it is hollow
Filter tip section, poly-lactic acid material section.Wherein tobacco product segment length is 11mm or so, this section of main contributions flue gas；Hollow filter tip
Segment length is 8mm or so, primarily serves certain cooling and heat-blocking action；Poly-lactic acid material section is by with a thickness of 0.05mm or so
Polylactic acid sheet material folding roll, filling rate be 30% or so, porosity be 70% or so, smoke contacts area about 4000
Square millimeter had not only played a supporting role as exhaust gases passes but also had had cooling effect.The product is undoubtedly given using poly-lactic acid material
Burning cigarette has not sticked environmental protection label to low temperature, is even more utilized that polylactic acid glass transition temperature is low, the more low physics of melt temperature
Feature, effectively reduces the temperature of sucking of flue gas, similar technology further include CN201510502839X,
CN2013800033776.However this poly-lactic acid material can melt when touching the flue gas of initial, excessive temperature, lead to cigarette
Gas channel jam, it is therefore necessary to enough distances be set with heater, this is exactly that IQOS product must be in the front end of polylactic acid
The reason of one section of hollow filter section is designed between heater.Nonetheless, after sucking, front end polylactic acid film is still
There is part fusing, the phenomenon that partial fume channel jam occurs.Furthermore development test result is also shown that Philips Mo Lisi
The flue-gas temperature of tobacco international corporation IQOS product is ideal not enough, still there is slight boiling hot mouth sense.
Adapt to the development trend of cigarette products simultaneously in order to solve the above problem, the applicant will be creative pure/modified to be gathered
Lactic acid particle is uniformly embedded into filter stick, using polylactic acid particle as heat absorption carrier, both effectively reduces flue-gas temperature
In turn avoid exhaust gases passes blockage problem caused by melting because of polylactic acid.When the polylactic acid particle of insertion and the contact surface of flue gas
Product can significantly reduce greatly the temperature of flue gas to a certain extent.In flue gas suction process, even if head temperature is higher to be caused
The softening of part polylactic acid or melting, but enough gaps are remained between polylactic acid particle, the stifled of large area will not be generated
Plug or deformation, because without being had an impact to exhaust gases passes.This filter stick for being embedded in polylactic acid particle can be leaned on directly
