Description
Technical Field
The utility model relates to a tobacco substitute technical field, a novel heating noncombustible suction product cooling section.
Background
With the enhancement of the desire of people for healthy life and the increasingly strict situation of controlling cigarettes, the novel cigarette designed by taking the concept of 'heating without combustion' becomes an important direction for researching and developing new-generation tobacco products and substitutes.
The non-combustible tobacco product is generally heated by physically separating the tobacco from the heat source, which is divided into: the cigarette comprises GLO of an electric heating type Fei Mo International iQOS and Ying Mei tobacco, REVO of a fuel heating type Reynolds company and a physicochemical reaction heating type, wherein the electric heating and the fuel heating are the technologies which occupy the leading positions at present, and for the electric heating and the carbon heating type heating non-combustion cigarettes, the problem of higher smoke temperature during smoking exists, meanwhile, as the tobacco raw materials of the heating non-combustion cigarettes are not combusted, the smoke release amount is less than that of the traditional cigarettes, and if the smoke temperature is reduced by adopting the traditional technical means of increasing filtering and ventilating dilution, the smoke volume of the product can be further reduced, and the smoking feeling of the product is seriously influenced. Therefore, the reasonable reduction of the smoke temperature is a key technology for heating the non-combustible cigarettes.
In order to solve the problem, the foreign enterprises such as Felmo International adopt polylactic acid films (PLA) as the material for cooling the smoke, and the technology is applied to the design of carbon-heated cigarettes. Although the polylactic acid film has a cooling effect, the polylactic acid film is easy to shrink when heated, and is not beneficial to the research and development of related technologies and products in China due to the problems of technical monopoly and the like, so that a plurality of other technologies for cooling smoke are generated.
For example, CN201710191528.5 reports a cigarette cooling filter stick added with heat absorbing gel, which is prepared by preparing heat absorbing gel with a melting point of 40-65 ℃, and making the heat absorbing gel into particles and threads, and then distributing the particles and threads in a common cigarette filter stick, or directly coating a certain amount of heat absorbing gel on the surface of a paper filter material and processing the particles into a paper filter stick, heating and melting the gel through the temperature of the mainstream smoke to absorb the heat of the smoke in the process of melting the gel, thereby reducing the temperature of the mainstream smoke of the cigarette and improving the smoking comfort of the cigarette and the cigarette which is not heated and combusted.
The above technical solution has several disadvantages:
firstly, on the same cigarette which is not burnt when being heated as the cigarette in the application, the heat absorption gel is coated on the paper filter material to prepare the paper filter stick by the scheme, but the hardness of the common paper filter stick is reduced, the common paper filter stick is more easily softened after being coated with the gel, the common paper filter stick is easy to collapse, and the forming of the paper filter stick is not facilitated.
Secondly, the heat absorption gel in the scheme is changed into liquid after absorbing heat, the liquidity is large, the filtering material can be blocked to a certain extent no matter the coating amount, the absorption resistance is increased, and the suction effect is influenced; therefore, only the coating amount of the heat absorption gel can be controlled, the upper limit value and the lower limit value of temperature reduction are influenced, and the application range of the whole scheme is finally reduced.
Thirdly, the heat absorption gel is essentially a means for adjusting smoke smell absorption and modulating and increasing aroma; because of the evaporation and volatilization of a small part of the heated smoke, the smoke is mixed with peculiar smell, and the smoke is harmful for the purpose of cooling the smoke, and the smoking quality is influenced.
Aiming at the two problems, the prior art also provides a solution, and the ' Chinese scientific and technical paper ' CAS No. 9 phase 935 and 939 in 2013, page 5, Experimental research on heat storage performance of paraffin type composite phase change material ', and patent CN201410624331.2 all report that the phase change material with excellent heat transfer performance is prepared by combining the composite phase change heat storage material with high adsorbability and high heat conductivity material, after the phase change material is added into a cigarette filter stick, the temperature of smoke sucked by the cigarette can be effectively reduced, and the problem after the phase change material is liquefied can be effectively solved; but the proposal still has the problem that the heat absorbing material is gasified and volatilized to influence the pumping quality.
