WIPO Patent Application WO/2019/072131
Kind Code:
A1
Abstract:
A smoking set, comprising: an elongated housing (10), a power supply provided in the housing (10), an opening (11) provided at an end of the housing (10), a cavity (12), for accommodating a cigarette (20), extending from the opening (11) in a longitudinal direction of the housing (10), and an airflow passage (13) extending in a longitudinal direction of the gap between the cigarette (20) and the housing (10), a barrier layer (30) being provided in the airflow passage (13) for weakening the transverse flow of air. The barrier layer (30), provided in the airflow passage (13), for weakening the transverse flow of air not only prevents heat from diffusing outwardly, but also has the effect of cooling a tube wall (14). The barrier layer (30) itself is made of a heat insulation material, which greatly reduces the speed of heat diffusion from the cavity (12) to the tube wall (14) while separating air into a plurality of portions; in addition, the barrier layer (30) and the flowing airflow have a larger contact area therebetween, and during smoking, the flowing of air effectively carries the heat of the barrier layer (30) itself and the outer wall of the housing (10), having the effect of cooling the tube wall (14) of the housing (10).
