The utility model belongs to novel cigarette smoking set field, in particular to hyperboloid rotary seal's heating smoking set. The smoking set comprises a deformable cigarette accommodating cavity 2 and a heating element fixing seat 3; the heating element fixing seat 3 comprises a hollow first frustum body; the cigarette accommodating cavity 2 comprises a hollow second truncated cone, and when the second truncated cone and the first truncated cone are in a first position of threaded connection, the cigarette accommodating cavity 2 has a first minimum inner diameter; when the second truncated cone and the first truncated cone are in the second position of threaded connection, the cigarette accommodating cavity 2 has the second minimum inner diameter. The utility model discloses adopt the hyperboloid structure that second truncated cone and first truncated cone formed for the first time, designed a cigarette and held the changeable smoking set of chamber minimum internal diameter. When the smoking set is used in cooperation with the oxygen-deficient heating type cigarette, the tobacco section of the cigarette can be sealed at the bottom of the cigarette accommodating cavity and the bottom of the heating element fixing seat, and the oxygen-deficient heating type cigarette does not need to be independently prepared with the sealed tobacco section, so that the preparation process of the cigarette is simplified. |
