| 摘要 |
一种烟品(2、34、38、42、44、48)包括：一可燃热源(4)，其具有相对正面(6)及背面(8)；一个或一个以上气流通道(18)，其从该可燃热源(4)之正面(6)延伸至该可燃热源(4)之背面(8)；一气溶胶形成基体(10)，其在该可燃热源(4)之背面(8)的下游；一烟嘴(14)，其在该气溶胶形成基体(10)之下游；以及一个或一个以上进气口(32、36)，其位于该可燃热源(4)之背面(8)的下游及该烟嘴(14)之上游。该一个或一个以上进气口(32、36)位于该可燃热源(4)之背面(8)与该气溶胶形成基体(10)之下游端间。在使用中，通过该气溶胶形成基体(10)所引入之空气系经由该一个或一个以上气流通道(18)及该一个或一个以上进气口(32、36)进入该烟品(2、34、38、42、44、48)及通过该气溶胶形成基体(10)所引入之至少一些空气与该可燃热源(4)之一可燃部分直接接触。; one or more airflow channels (18) extending from the front face (6) to the rear face (8) of the combustible heat source (4); an aerosol-forming substrate (10) downstream of the rear face (8) of the combustible heat source (4); a mouthpiece (14) downstream of the aerosol-forming substrate (10); and one or more air inlets (32, 36) located downstream of the rear face (8) of the combustible heat source (4) and upstream of the mouthpiece (14). The one or more air inlets (32, 36) are located between the rear face (8) of the combustible heat source (4) and a downstream end of the aerosol-forming substrate (10). In use, air drawn through the aerosol-forming substrate (10) enters the smoking article (2, 34, 38, 42, 44, 48) through the one or more airflow channels (18) and the one or more air inlets (32, 36) and at least some of the air drawn through the aerosol-forming substrate (10) comes into direct contact with a combustible portion of the combustible heat source (4). |
