Heat-not-burn cigarette filter stick with cooling and heat-insulating properties and cigarette

Abstract

The invention discloses a heat-not-burn cigarette filter stick with cooling and heat-insulating properties. The heat-not-burn cigarette filter stick comprises: a supporting cooling section (2), a ventilating section (3), a filtering section (4) and heat-insulating forming paper (5) wrapping the supporting cooling section (2), the ventilating section (3) and the filtering section (4). The supporting cooling section (2) is provided with a pipe wall (22) and a pipe cavity (23), and a plurality of cooling lines (21) are arranged on one side, close to the pipe cavity (23), in the pipe wall (22). The heat-insulating forming paper (5) has a plant fiber paper layer (51) and a heat insulation layer (52). The heat insulation layer (52) can prevent smoke temperature from being transmitted to the surface of a filter stick, therefore the problem that the filter tip scalds mouth is solved. Furthermore, due to the existence of the heat insulation layer (52), scorching smoke is completely isolated inthe filter stick, the temperature is reduced through a cooling material, and the utilization rate of the cooling material is increased. Meanwhile, the cooling lines (21) are arranged on the inner sideof the pipe wall (22), the cooling effect is improved, and meanwhile comfortable smoking experience and a good fuming amount are provided for consumers.

Description

technical field [0001] The patent of the invention relates to the technical field of production of heat-not-burn cigarettes, in particular to a heat-not-burn cigarette filter rod and cigarette stick with cooling and heat-insulating properties. 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 coolin...

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

In other words, simply increasing the amount of cooling material will not effectively improve the cooling effect of the cooling section. Instead, after a few puffs, the phase change material will collapse and block the airflow channel, and the suction resistance will increase significantly. , affecting the pumping experience
