使用时，空气由加热不燃烧烟支的气溶胶发生基材10的外端进入，穿透整个加热不燃烧烟支到达滤嘴30的外端，加热气溶胶基材所产生的气溶胶通过多个开放通道进入气流阻力调节件20，气流阻力调节件20具有连接该多个开放通 道的一空间，该空间对气流阻力进行调整；气流阻力调节件20还具有连接滤嘴30的多个开放通道的另一空间，该空间不仅提供多个进入滤嘴30的点，还可以进一步调整气溶胶的气流阻力，给吸烟者提供好的吸烟体验。When in use, air enters from the outer end of the heating non-combustible cigarette aerosol generating substrate 10, penetrates the entire heating non-combustible cigarette to the outer end of the filter 30, and the aerosol generated by heating the aerosol substrate passes through more Two open channels enter the airflow resistance adjusting member 20. The airflow resistance adjusting member 20 has a space connecting the plurality of open channels, and the space adjusts the airflow resistance; the airflow resistance adjusting member 20 also has a plurality of open channels connected to the filter 30 This space not only provides multiple points for entering the filter 30, but also can further adjust the airflow resistance of the aerosol to provide smokers with a good smoking experience.

于本实施例中，加热不燃烧烟支的参数如下表所列。In this embodiment, the parameters of heating and not burning cigarettes are listed in the following table.

相较于现有技术，本发明提供了一种加热不燃烧烟支的包装材料，所述包装材料包括一包装材料基材50以及形成于所述包装材料基材50上的至少一隔热层40，所述隔热层40具有粘性。该包装材料可减少加热不燃烧烟支的气溶胶发生基材10到加热不燃烧烟支外表面的热量散失，还可减少包装材料与加热不燃烧烟支内部零件之间的间隙，从而减少透过包装材料进入加热不燃烧烟支内部的气流，进而减少加热不燃烧烟支受热部分的热量损失，从而为吸烟者更好地控制气溶胶的浓度。另，这种粘性的隔热层40也省去了给加热不燃烧烟支的滤嘴30加接装纸，减少了工序，节约了成本。包装材料减少透过其的热量损失，从而能够让加热源能在较低的工作温度下把气溶胶发生基材10加热到应有的温度，继而加热源较低的加热温度可以允许去掉气溶胶冷却件的必要性。在去掉 气溶胶冷却件的情况下，加热不燃烧烟支的制造过程也会得到很大的简化。另一方面，典型的加热不燃烧烟支的包装材料是木纤维制成，在环绕内部零件之后由胶水进行粘合。隔热层40的粘性可以保证内部零件与包装材料之间几乎存在零间隙，这种间隙的消除和减少可以显著改善加热不燃烧烟支的气溶胶发生基材10所产生的气溶胶温度和质量。Compared with the prior art, the present invention provides a packaging material for heating non-burning cigarettes. The packaging material includes a packaging material base 50 and at least one heat insulation layer formed on the packaging material base 50 40. The heat insulation layer 40 has viscosity. The packaging material can reduce the heat loss from the aerosol generating substrate 10 of the heat-not-burn cigarette to the outer surface of the heat-not-burn cigarette, and can also reduce the gap between the packaging material and the internal parts of the heat-not-burn cigarette, thereby reducing penetration The airflow entering the heat-not-burn cigarette through the packaging material, thereby reducing the heat loss of the heated part of the heat-not-burn cigarette, so as to better control the aerosol concentration for smokers. In addition, this viscous heat-insulating layer 40 also eliminates the need to add tipping paper to the heat-not-burning cigarette filter 30, which reduces the number of processes and saves costs. The packaging material reduces the heat loss through it, so that the heating source can heat the aerosol generating substrate 10 to a proper temperature at a lower working temperature, and then the lower heating temperature of the heating source can allow the aerosol to be removed The necessity of cooling parts. In the case of removing the aerosol cooling element, the manufacturing process of the heat-not-burn cigarette will also be greatly simplified. On the other hand, the typical packaging material for heat-not-burn cigarettes is made of wood fiber, which is bonded by glue after surrounding the internal parts. The viscosity of the thermal insulation layer 40 can ensure that there is almost zero gap between the internal parts and the packaging material. The elimination and reduction of this gap can significantly improve the temperature and quality of the aerosol generated by the aerosol generating substrate 10 of heating non-burning cigarettes. .

以上所揭露的仅为本发明的优选实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明申请专利范围所作的等同变化，仍属本发明所涵盖的范围。The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of rights of the present invention cannot be limited by this. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope of the present invention.
