Abstract (en)
[origin: EP4005422A1] The present disclosure relates to the field of heating non-combustion smoking set, and in particular, to a plug-in oxygen-deficient heating smoking set, as well as a cigarette system and smoking method containing the smoking set. The smoking set includes a smoke extraction element (6) that can be detached from the smoking set or fixed in a cigarette accommodating cavity (3); the smoke extraction element (6) includes a hollow smoke extraction cone (6-1) and a mainstream smoke forming tube (6-2) that can be fixedly or detachedly sleeved on the periphery of a cone body (6-1-1) of the smoke extraction cone (6-1); the mainstream smoke forming tube (6-2) has an internal cavity (6-2-1), and the outline of the cavity (6-2-1) has a Venturi tube structure. The mainstream smoke forming tube of the present disclosure has an internal cavity, and the outline of the cavity has a Venturi tube structure, the smoke extraction effect is enhanced, and the oxygen content of the tobacco section can be reduced while the fresh smoke generated in the enclosed space can be extracted, which can meet the requirements of smoke concentration.
