[0049] Result Detection

[0050] 400 tobacco matrixes mentioned above were prepared, and a sucking experiment was carried out with the cooperation of a heater.

[0051] A specific sucking experiment was as follows:

[0052] (1) inserting the heat-not-burn cigarette into the heating cavity through the cigarette insertion opening and contacting with the positioning piece;

[0053] (2) pressing a power switch to start heating, so that the heat of the heating element heated the heat-not-burn tobacco matrix for people to suck; and

[0054] (3) rotating for at least 30 degrees after sucking, and pulling out the heat-not-burn cigarette.

[0055] A fall-out rate of the cut tobacco after heating and sucking was evaluated, wherein a score of 5 referred to that no cut tobacco fell out basically; a score of 4 referred to that a small amount of cut tobacco fell out; a score of 3 referred to that part of the cut tobacco fell out obviously; a score of 2 referred to a large number of cut tobacco fell out; and a score of 1 referred to that all the cut tobacco fell out basically.

[0056] A method in ISO standard 6565:2002 was used to measure the sucking resistance. It should be noted that, when testing the sucking resistance, measurement results of cigarettes inserted into the heating cavity of the heater are as shown in Table 3.

TABLE-US-00003 TABLE 3 Serial Sucking number resistance (kPa) Embodiment 1 0.251 Embodiment 2 0.445 Embodiment 3 0.321 Embodiment 4 0.283 Embodiment 5 0.246 Embodiment 6 0.346 Embodiment 7 0.575 Embodiment 8 0.484 Embodiment 9 0.535 Embodiment 10 0.433 Embodiment 11 0.258

COMPARATIVE EXAMPLE 1

[0057] A heat-not-burn tobacco matrix was formed by rolling tobacco sheet, wherein the tobacco sheet were the same as those in Embodiment 1, with a thickness of 0.1 mm, a length of 2 mm and a width of 1 mm. A score of a fall-out rate of the cut tobacco after sucking was 4, and a sucking resistance was 0.935 kPa.

COMPARATIVE EXAMPLE 2

[0058] A heat-not-burn tobacco matrix was formed by disorderly mixing tobacco sheet and expanded cut tobacco and then rolling, wherein the tobacco sheet were the same as those in Embodiment 1, with a thickness of 0.1 mm, a length of 2 mm and a width of 1 mm. A fill-rate of the expanded cut tobacco was 7.12 cm.sup.3/g, a whole cut rate of the expanded cut tobacco was 83%, and a mass fraction of the expanded cut tobacco was 5%. A score of a fall-out rate of the cut tobacco after sucking was 3, and a sucking resistance was 0.845 kPa.

COMPARATIVE EXAMPLE 3

[0059] A heat-not-burn tobacco matrix was formed by disorderly mixing tobacco sheet and expanded cut tobacco and then rolling, wherein the tobacco sheet were the same as those in Embodiment 1, with a thickness of 0.1 mm, a length of 2 mm and a width of 1 mm. A fill-rate of the expanded cut tobacco was 7.12 cm.sup.3/g, a whole cut rate of the expanded cut tobacco was 83%, and a mass fraction of the expanded cut tobacco was 50%. A score of a fall-out rate of the cut tobacco after heating and sucking was 5, and a sucking resistance was 0.445 kPa, but the heat-not-burn tobacco matrix had a very poor sucking taste and bland aroma.

[0060] From the foregoing embodiments and comparative examples, it can be seen that the tobacco matrix formed by rolling the tobacco sheet without the expanded cut tobacco in Comparative Example 1 is easy to fall out after heating and sucking, which is obviously inferior to the embodiments; the content of the expanded cut tobacco added in Comparative Example 2 is too low, and the phenomenon of the cut tobacco falling out after heating and sucking of the obtained tobacco matrix is also obvious, which is not as good as that of the embodiments; and the addition amount of the expanded cut tobacco in Comparative Example 3 is too large, which can control the fall-out rate of the cut tobacco well, but excessive addition of the expanded cut tobacco will damage overall aroma and overall sensory evaluation of the tobacco matrix.

[0061] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly illustrating the present invention, but are not intended to limit the implementations of the present invention. For those of ordinary skills in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary or possible to exhaust all the implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall all fall within the scope of protection claimed by the present invention.
