A heat-not-burn tobacco aerosol source member or consumable includes a first heating section with a front end. The first heating section contains a liquid aerosol precursor existing as a free liquid in an unbound form. A second heating section is provided with a mouth end. The second heating section contains a solid tobacco substrate. A first thermal barrier that is vapor permeable but liquid impermeable is located between the first heating section and the second heating section. The system has a simple structure and lowers processing costs, and greatly reduces undesirable harmful chemicals because of its lower heating temperatures for the first and second heating sections of the consumable.
一种加热不燃烧烟草气溶胶源部件或消耗品包括一个带有前端的第一加热段。第一加热部分包含以未结合形式存在的自由液体气溶胶前体。第二加热部分具有口端。第二加热段包含固体烟草基质。在第一加热段和第二加热段之间有一个可渗透蒸汽但不可渗透液体的第一隔热层。该系统结构简单,降低了加工成本,并且由于其第一和第二加热段的加热温度较低,大大减少了有害
化学物质。
