A twelfth aspect of the invention provides the use of a heated cigarette according to any of the seventh aspects in a heated smoking article.

Herein, "upstream" to "downstream" are relative terms. When the smoke section or the heating cigarette is smoked, the smoke flow direction in the smoke section or the heating cigarette is from 'upstream' to 'downstream'.

Herein, "proximal lip end", "distal lip end" are relative terms referring to the two ends of a smoking article or a segment thereof, respectively. "proximal lip" refers to the end of a smoking article or a segment thereof that is closer to the user's lips when the smoking article is in use. "distal lip" refers to the end of the smoking article or a segment thereof that is farther from the user's lips when the smoking article is in use.

Accordingly, if the smoking article or a segment thereof is segmented, the segment comprising the proximal lip end is referred to herein as the "proximal lip segment" and the segment comprising the distal lip end is referred to herein as the "distal lip segment".

I.e. the smoking article presents a "proximal lip end", "distal lip end", a proximal lip segment "," distal lip segment ". Accordingly, there is also a "proximal lip end", "distal lip end", proximal lip segment "," distal lip segment "of a certain segment of the smoking article.

The smoking article may be a heated cigarette or a smoke generating segment.

Compared with the prior art, the invention has the following beneficial effects:

1. the invention creatively designs a pluggable smoke generating section which is characterized in that a near-lip section is provided with cavity sections 1-6. The smoke generating segment may be used alone as a cartridge, for example, to add heated puffs to a smoking article having a cooling segment and a filtering segment. The smoke generating segment is particularly suitable for being added into a smoking set with a filtering segment for sucking, because the smoking set is provided with the cavity segments 1-6, the volume of the matched smoking set can be reduced, and the cavity segments are not needed to be reserved in the smoking set. The smoke generating section can be further combined with the hollow cooling section 2-4 and/or the filtering section 2-2 to form a cigarette, and then the cigarette is inserted into a smoking set for heating and sucking.

2. The far lip section of the smoke section of the heating cigarette is provided with the heat homogenizing piece 1-1, and both ends of the cigarette bullet are respectively provided with the heat homogenizing piece 1-1 and the blocking piece 1-4 for blocking granular smoke substances. And, after the cartridge is heated, the air in the air chamber 1-1-1 of the heat homogenizing member 1-1 includes the original air and the air which enters subsequently is heated into hot air. The hot air enters the smoking material through the holes on the proximal lip end of the heat distribution member 1-1 for air flow heating. The introduction of air flow heating greatly improves the heating uniformity of the fuming material, and enables the distal lip end fuming material to be fully heated by contacting with high-temperature air. Therefore, the heat homogenizing member 1-1 has the effects of blocking the granular smoke substance and heating the air flow at the same time.

3. From the standpoint of the manufacturing process of the particle-type smoke generating segment, such a heat homogenizing member 1-1 with a hole at the bottom is also very easy to be filled into a hollow paper tube, and can be directly plugged into the hollow paper tube from the far lip end or the near lip end. Therefore, the smoke generating segment is very suitable for the filling process of the granular heating cigarettes.

4. When the smoke generating section or the heating cigarette is used, the heating mode comprises the following three modes:

method one, cycle Xiang Jiare + end gas flow heating:

the circumferential heating tube can be used for heating the smoke generating section or the cigarette, the heating tube can be used for directly heating the smoke generating section or the cigarette shell, heat is conducted to the smoke generating substance 1-2 through the smoke generating section or the cigarette shell, and the air in the heat homogenizing part 1-1 can be heated to comprise original air and subsequently entering air, so that the hot air can be used for carrying out air flow heating on the smoke generating substance 1-2;

method two, center heating+end air flow heating:

the central heating element is used for heating a smoke generating section or heating cigarettes, the heating element is inserted into the heat homogenizing piece 1-1 or extends into the smoke generating substance 1-2, the air in the central heating element heating heat homogenizing piece 1-1 comprises original air and subsequently entering air, so that the hot air carries out air flow heating on the smoke generating substance 1-2, and the central heating element can also directly conduct heat to the smoke generating substance 1-2;

method three, end air flow heating:

the soaking piece 1-1 is a ferromagnetic heating element and is matched with an electromagnetic heating type smoking set for use, and the soaking piece 1-1 heats air (including original air and subsequently entering air) in the smoking material after heating, so that the hot air heats the smoking material 1-2 in an airflow manner.

5. The pluggable smoke generating section of the invention can also be suitable for being plugged with any filter tip, and cigarettes can be formed for users to suck after plugging.

5. If the heat homogenizing member 1-1 is in a cup-shaped structure with a standing side, when the smoke generating section 1 is manufactured by a rolling process or a filling process, attention must be paid to the problem of orientation of the heat homogenizing member 1-1, and the bottom end of the cup of the heat homogenizing member 1-1 is close to a smoke generating substance. And thus, an identification device for identifying the orientation of the heat homogenizing part 1-1 must be added, which greatly increases the cost and complexity of the manufacturing process.

The radial partition plates 1-1-2 are creatively arranged in the middle of the heat homogenizing part 1-1, and the axial section of the heat homogenizing part 1-1 is similar to an H shape. Thus, the two ends of the heat homogenizing element 1-1 face the smoke generating section 1 with the same effect, and the problem of the facing of the heat homogenizing element 1-1 is not considered. Therefore, the identification device for identifying the orientation of the heat homogenizing part 1-1 is avoided, the cost is greatly reduced, and the manufacturing process is simplified.
