Heat-not-burn cigarette filter stick with heat insulation performance and cigarette comprising the same

Abstract

The invention discloses a heat-not-burn cigarette filter stick with heat insulation performance. The heat-not-burn cigarette filter stick comprises a supporting section (1), a cooling section (2), a filtering section (3) and heat insulation forming paper (4) wrapping the supporting section (1), the cooling section (2) and the filtering section (3). The heat insulation forming paper (4) has a plantfiber paper layer (41) and a heat insulation layer (42). Compared with the prior art, the invention adopts an opposite way, the heat dissipation effect of the forming paper or tipping paper wrappingthe filter stick is not improved, on the contrary, the heat insulation layer (42) is arranged on the inner side of the forming paper, when smoke passes through the filter stick, the heat insulation layer (42) prevents the smoke temperature from being transmitted to the surface of the filter stick, therefore the problem that the filter tip scalds the mouth is solved. Furthermore, due to the existence of the heat insulation layer (42), the scorching smoke is completely isolated in the filter stick, and when the smoke passes through the cooling section (2), the temperature is reduced by a coolingmaterial, so that the utilization rate of the cooling material is improved. And the heat insulation forming paper (4) is easy to process, and the compounding efficiency of the filter stick is not influenced.

Description

technical field [0001] The patent of the present invention relates to the technical field of production of heat-not-burn cigarettes, in particular to a heat-not-burn cigarette filter rod with heat insulation performance and a cigarette containing it. Background technique [0002] As consumers pay more attention to health issues and demand for personalized experience of cigarette products, the tobacco industry has continuously responded to the upgrading of consumers' needs and developed various cigarettes with reduced tar and harm. Among them, heat-not-burn cigarettes can provide a healthier smoking experience while satisfying consumers' sensory needs for cigarette products because their cigarettes are heated in a different way than traditional cigarette products. [0003] Heat-not-burn cigarette filter rods mainly include a support section, a cooling section and a filter section to reduce the temperature of the smoke delivered to the consumer's mouth. At present, most of the...

AI Technical Summary

Problems solved by technology

However, in the actual cigarette smoking process, these two improved methods have disadvantages. First, when the smoke passes through the filter rod, part of the temperature of the smoke is transferred to the surface of the filter rod due to the heat transfer of the filter rod material, which directly leads to The mouth is too hot, and most consumers think that the surface temperature of the heated cigarette filter rod is high, which burns the skin of the mouth

On the other hand, part of the temperature is lost to the surface of the filter rod, and only the flue gas passing through the cooling material in the cooling section can achieve the cooling effect. The cooling effect is slightly improved, but the cost of the cooling section is greatly increased
