Technical Field

The invention relates to the technical field of production of heating non-burning cigarettes, in particular to a heating non-burning cigarette filter stick with heat insulation performance and a cigarette comprising the same.

Background

Along with the attention of consumers to health problems and the improvement of the demand of individualized experience of cigarette products, the tobacco industry continuously responds to the demand upgrade of consumers and develops various cigarettes with tar and harm reduction. The cigarette heating mode of the non-combustion type cigarette is different from that of the traditional cigarette product, so that the cigarette heating mode can meet the sensory requirements of consumers on the cigarette product and provide healthier smoking experience.

The heating non-combustible cigarette filter stick mainly comprises a supporting section, a cooling section and a filter tip section, reduces the temperature of smoke delivered to the mouth of a consumer, the cooling section is mostly a gathered polylactic acid film at present, adhesion is easy to occur between the cooling section and the cooling section after heat absorption, the smoke volume is reduced, the cooling effect is not ideal, and the temperature entering the mouth of the consumer is high. To address this problem, researchers are now largely two improvements: on one hand, the using amount of the cooling material of the cooling section is increased, namely the effect of reducing the smoke temperature of the cooling section is further improved, and on the other hand, the heat dissipation effect of the forming paper or the tipping paper wrapping the filter stick is improved, so that part of the smoke temperature is dissipated to the environment through the filter stick to reduce the temperature. However, in the actual cigarette smoking process, the two improvement methods have disadvantages, one is that when smoke passes through the filter stick, partial temperature of the smoke is transferred to the surface of the filter stick along with the heat transfer effect of the filter stick material, so that the filter tip is directly too hot, and most consumers consider that the surface temperature of the cigarette filter stick is high and the filter tip is hot. On the other hand, partial temperature is dissipated to the surface of the filter stick, the cooling effect is only achieved through smoke passing through the cooling material of the cooling section, the utilization rate of the cooling material is low, the cooling effect is not fully exerted, the using amount of the cooling material is further increased, the cooling effect is only slightly improved, and the cost of the cooling section is greatly improved.

Therefore, the preparation of the cigarette with the advantages of no nozzle burning on the surface of the filter stick and high utilization rate of the cooling material of the cooling section is desirable.

The present invention has been made to solve the above problems.
