烟气回流段靠近增香段2一侧上下分别设有一个进气孔3，位于最上端的第一气流隔板置于上侧进气孔3的下方，其一端与增香段2接触密封，另一端与滤嘴段间隔一定距离形成开口，位于开口下方的第二气流隔板一端与滤嘴段接触密封，另一端与增香段2间隔一定距离形成开口，这样第一气流隔板和第二气流隔板交错设置，使得上第一气流隔板与烟气回流段上侧壁之间、第一气流隔板端部与滤嘴段形成的开口、第二气流隔板端部与增香段2形成的开口形成来回弯折的烟气回流气路4，烟支加热后，烟气通过进气孔3进入，通过烟气回流气路4，在烟气回流段中增加烟气的流通距离，热气流与气流隔板5及内壁进行热交换降低烟气的温度，通过出气孔6流出后，依次进入到实心过滤嘴7和空心过滤嘴8，最后烟气温度被降到45℃以下。
第三气流隔板、第四气流隔板与下侧进气孔3的设置与上述描述类似，在此不再赘述。
在本实例中，烟草段1由烟丝、烟草薄片、雾化剂、辅料、烟草提取物、烟用香精香料等组成，其中，烟丝占总重量的70％，烟草薄片占总重量的14％，雾化剂由甘油：乙二醇按照质量比3:1组成，占总重量的12％，辅料占总重量的1％，烟草提取物占总重量的2.8％，香精香料占总重量的0.2％。

较佳的，可在气流隔板5的表层敷设吸附载体，吸附载体上附着有香精香料，可达到对烟气进行增香处理的效果。
本实例制备的新型卷烟结构，可明显的降低卷烟烟气的温度，烟草香味明显。
实施例三

在本实例中，烟草段1由烟丝、烟草薄片、雾化剂、烟草提取物、烟用香精香料等组成，其中，烟丝占总重量的60％，烟草薄片占总重量的15％，雾化剂由甘油：乙二醇：水按照质量比10:10:1组成，占总重量的20％，烟草提取物占总重量的4.9％，香精香料占总重量的0.1％。
在本实例中，增香段2中由醋酸纤维包裹的含有调配好的烟用香 精香料的易碎胶囊9，在加热烟草段1之前，将易碎胶囊9捏破，香精香料释放出来，利用烟草段1的热气流将香精香料带出来，增加烟气的香气饱满度。
