Description
Technical Field
The invention relates to the technical field of heating cigarettes, in particular to an electromagnetic induction heating cigarette and a preparation method thereof.
Background
Traditional tobacco maintains smoldering state after being ignited, and utilizes the temperature generated by smoldering to heat tobacco raw materials near a combustion area, releasing smoke for smoking. In this process, the tobacco material temperatures at different locations are different from one another according to the difference in location from the combustion cone. The smoke release process of the traditional tobacco products is carried out in a system with a large temperature change range and poor heating uniformity. The temperature instability leads to very complex composition of the compounds in the smoke constituents, which also leads to an affected stability of the smoke suction quality and also to a difficult control of the release of many harmful chemical constituents.
In recent years, scientific researches show that the combustion temperature of cigarettes is effectively controlled and reduced, the release amount of harmful components in smoke can be obviously improved, and the safety of tobacco products is improved. Based on this theory, a heating non-combustible product was developed. The heating non-combustion products are obtained by heating and baking tobacco materials through a heating element, and controlling the heating temperature to be about 300 ℃ so that the tobacco can release smoke and still keep a non-combustion state. Compared with the traditional cigarette, the temperature stability of the smoke released by the tobacco is improved to a great extent by heating the non-combustible tobacco, and the harm of the product is further reduced.
Electromagnetic induction heating is to generate alternating magnetic field through high frequency current, cut alternating magnetic force lines corresponding to the metal surface to generate alternating current (namely vortex), the vortex makes metal atoms move randomly at high speed, and atoms collide and rub with each other to generate heat energy, so as to play a role in heating articles. Because the iron container generates heat, the heat conversion efficiency is far higher than that of the traditional heating mode of contact type heat transfer. The patent document with publication number CN108835707a discloses an electromagnetic induction heating cigarette, which comprises a tobacco section and a filter tip section, wherein the tobacco section is wrapped by tobacco section cigarette paper, and the tobacco section is curled after being compounded by metal foil and tobacco to form a cigarette-shaped structure, wherein a certain gap is arranged between layers in the cigarette-shaped structure.
In this application, first, tobacco section is curled after being compounded by metal foil and tobacco and forms, and wherein, metal foil can be curled, must have better ductility and elasticity, and this can lead to its after the crimping shaping, by external force pinching, just be out of shape easily to lead to its layer and the clearance that supplies the flue gas to circulate between the layer to seal, influence the problem of flue gas circulation. Secondly, the tobacco and the metal foil are pressed together, when the metal foil is deformed by external force, the deformation capability of the tobacco and the metal foil is inconsistent, and gaps are generated between the tobacco and the metal foil, so that the tobacco is easy to fall off from the metal foil.
