The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

As shown in fig. 1 and 2, the sectional heating cigarette heating smoking set provided by the embodiment of the present application comprises: heating core 100, heating ring 200, fixed tube 300, base 400.

The fixing tube 300 is provided with an axial through hole 310, and the axial through hole 310 comprises an upper section hole 311, a middle section hole 312 and a lower section hole 313 which are sequentially arranged from top to bottom; the inner wall of the middle section hole 312 of the axial through hole 310 is provided with an annular groove. The heating ring 200 is positioned in the middle section hole 312 of the axial through hole 310, the heating ring 200 is embedded in the annular groove, and the inner wall of the heating ring 200 is flush with the inner wall of the axial through hole 310; the base 400 is fixedly connected with one end of the fixed tube 300; the heating core 100 is located in the lower hole 313, and one end of the heating core 100 extends out of the axial through hole 310 and is fixedly connected with the base 400.

In this embodiment, the cigarette 10 includes a filter section 11, a cooling section 12, a hollow section 13, a sheet upper section 14 and a sheet lower section 15, which are connected in sequence. When smoking the cigarette 10, the cigarette 10 is inserted into the axial through hole 310. The hollow section 13, the sheet upper section 14 and the sheet lower section 15 are located in the axial through hole 310, the heating core 100 is inserted into the sheet lower section 15, and the sheet upper section 14 contacts with the heating ring 200.

In this embodiment, since the heating ring 200 needs to heat the outer periphery of the upper sheet segment 14, the cross section of the axial through hole 310 is circular, and the diameter of the axial through hole is the same as the outer diameter of the cigarette 10 or slightly larger than the outer diameter of the cigarette 10, so that the upper sheet segment 14 of the cigarette 10 can be better contacted with the heating ring 200, and the heating ring 200 can sufficiently heat the upper sheet segment 14.

As will be appreciated by those skilled in the art, to facilitate insertion of the cigarette 10 into the axial through hole 310, the heating ring 200 is disposed with its inner wall flush with the inner wall of the axial through hole 310 in this embodiment. Specifically, the inner wall of the heating ring 200 is flush with the inner wall of the axial through hole 310, so that on one hand, the heating ring 200 is prevented from protruding the side wall of the axial through hole 310 to cause the cigarette 10 to be inserted into the axial through hole 310, and the cigarette 10 can be ensured to be smoothly inserted into the axial through hole 310; on the other hand, the inner wall of the heating ring 200 is prevented from sinking relative to the inner wall of the axial through hole 310, so that the heating ring 200 cannot contact with the cigarette 10 after the cigarette 10 is inserted into the axial through hole 310, and the heating effect is not affected.

It can be further understood by those skilled in the art that the hollow section 13 is inserted into the axial through hole 310, so as to prevent the cigarette 10 from being broken due to too short insertion into the axial through hole 310, and at the same time, to perform the function of preliminary cooling.

In this embodiment, after the cigarette 10 is inserted into the axial through hole 310, the heating core 100 heats the lower sheet segment 15 of the cigarette 10 first, so that the lower sheet segment 15 generates smoke for the consumer to smoke. In this process, in order to avoid the smoke temperature from being too high and burning the consumer, the cigarette 10 is further provided with the cooling section 12 extending out of the axial through hole 310, the cooling section 12 is exposed relative to the axial through hole 310, that is, the length of the fixing tube 300 is slightly greater than the sum of the lengths of the hollow section 13, the upper sheet section 14 and the lower sheet section 15, and the length of the axial through hole 310 is equal to the sum of the lengths of the hollow section 13, the upper sheet section 14 and the lower sheet section 15. The higher smog of temperature through heating thin slice hypomere 15 production at first carries out primary cooling through cavity section 13, carries out the secondary cooling through cooling section 12 again, supplies the suction of consumer through filter segment 11 at last for smog gradually cools down, and when making smog reach filter tip 11 department, the temperature of smog just suits, can avoid scalding the consumer.

When the lower segment 15 of the sheet is sucked 5 to 6 times, the amount of smoke obtained by heating the lower segment 15 of the sheet by the heating core 100 is gradually reduced, and at this time, the heating ring 200 starts to heat the upper segment 14 of the sheet to generate smoke so as to supplement the shortage of smoke of the lower segment 15 of the sheet. Thereby ensuring that the amount of smoke is maintained at a relatively constant level, resulting in a consistent taste for the consumer. When about 12 puffs are taken, the heating ring 200 and the heating core 100 stop heating the cigarette 10, i.e. the cigarette needs to be replaced. Of course, those skilled in the art may make the specific arrangement according to the variety of the cigarette 10.

As can be seen from the above, in the sectional heating cigarette heating smoking set provided in the embodiment of the present application, the heating core 100 is used to heat the lower sheet segment 15 from the inside, so that the lower sheet segment 15 is heated from the inside, and the heat is gradually transferred to the outer periphery, and at this time, the center of the upper sheet segment 14 is also slightly heated by the influence of the heating core 100. After the lower segment 15 of the sheet is sufficiently heated, the heating ring 200 is used to heat the upper segment 14 of the sheet, the upper segment 14 of the sheet is heated from the outer periphery, and the heat is gradually transferred to the center, at this time, the heat generated by the heating ring 200 can also spread to the lower segment 15 of the sheet, so that the outer periphery of the lower segment 15 of the sheet is slightly heated. Therefore, the heating ring 200 and the heating core 100 are heated complementarily, so that the upper sheet section 14 and the lower sheet section 15 can be heated sufficiently, the heating sufficiency is improved, and meanwhile, different parts of the cigarette are controlled and heated at different time, so that the smoke generated in the heating process of the cigarette is released continuously and uniformly.
