- the first segment 11 includes an aerosol-generating material excluding nicotine

- the component and content of the aerosol-generating material included in the first segment 11 and the component and content of the aerosol-generating material included in the second segment 12 may not be the same. Therefore, in order for a user to have a satisfactory feeling of smoking, the first segment 11 and the second segment 12 need to be heated to different temperatures. For example, when the second segment 12 is heated to a temperature suitable for the first segment 11 , a user may feel a burnt taste. Alternatively, when the first segment 11 is heated to a temperature suitable for the second segment 12 , sufficient aerosol may not be generated.
- the first segment 11 and the second segment 12 may be heated to different temperatures by different heaters. For example, if the first segment 11 is heated to A ° C. by a heater to produce a sufficient amount of aerosol, and the second segment 12 is heated to B ° C. by another heater to volatilize an appropriate amount of nicotine, and a user may have a satisfactory feeling of smoking.
- the first segment 11 and the second segment 12 may be heated by a single heater. In this case, it is difficult to heat the first segment 11 and the second segment 12 to different temperatures. Thus, even if the first segment 11 and the second segment 12 are heated by one heater, at least one of the wrappers 15 may include a thermally conductive wrapper so that each of the first segment 11 and the second segment 12 may be heated to an appropriate temperature. An example in which the first segment 11 and the second segment 12 are heated by a single heater will be described later with reference to FIGS. 3 and 4 .
- the first segment 11 and the second segment 12 may include an aerosol-generating material, and the aerosol-generating material may include a moisturizing material.
- the moisturizing material may include glycerin, propylene glycol, or a combination thereof, but is not limited thereto.
- glycerin and propylene glycol may be combined at a ratio of 8:2.
- the combination ratio is not limited to the example described above.
- the moisturizing material included in the first segment 11 may contribute to the amount of the aerosol produced. In other words, the total amount of atomization of the aerosol-generating article 1 may be determined by the weight of the moisturizing material included in the first segment 11 .
- the moisturizing material included in the second segment 12 may be involved in the smoking taste of the aerosol-generating article 1 . In other words, the smoking taste of the aerosol-generating article 1 may be determined by the nicotine and the moisturizing material included in the second segment 12 .
- the first segment 11 In order to generate a sufficient amount of atomization from the aerosol-generating article 1 , the first segment 11 must contain a sufficient amount of moisturizing material. In particular, the first segment 11 may include a greater amount of moisturizing material than the second segment 12 . However, when an excessive moisturizing material is included in the first segment 11 , the moisturizing material may leak out of the aerosol-generating article 1 . This is undesirable in view of the appearance of the aerosol-generating article 1 .
- the amount of the moisturizing material included in the second segment 12 increases, the amount of heat required for the moisturizing material to vaporize also increases. Accordingly, the amount of vaporization of nicotine and other aerosol-generating materials included in the second segment 12 is reduced, and results in a decrease in the satisfaction of a smoking feeling of the user.
- the first segment 11 includes a moisturizing material in an amount capable of ensuring a sufficient amount of atomization and preventing a change in the appearance of the aerosol-generating article 1 .

- Table 1 shows the results of analyzing the weight (unit: mg) of components included in the aerosol for each weight (unit: mg) of the moisturizing material included in the first segment 11 .
- the aerosol means the sum of the aerosols discharged to the outside of the aerosol-generating article 1 by a predetermined number of puffs.
- TPM total particulate matter
- the content of the moisturizing material in the first segment 11 is more than a certain amount, it may be seen that the effect of nicotine in the second segment 12 being discharged to the outside of the aerosol-generating article 1 is small.
- the TPM in the aerosol is greater than or equal to about 40 mg, a result similar to the content of nicotine shown in Table 1 was confirmed.
- the content of the moisturizing material in the first segment 11 is about 30 mg, it is confirmed that about 40 mg of TPM is contained in the aerosol. That is, when the moisturizing material in the first segment 11 is greater than or equal to about 40 mg, it is confirmed that a sufficient amount of atomization is ensured and an adequate amount of nicotine transfer may be ensured.
- leakage may mean that the moisturizing material oozes out of the surface of at least one wrapper surrounding the first segment 11 .

- The technical problem to be solved by the present inventive concept is to provide an aerosol-generating article including a segment containing nicotine and another segment containing an aerosol-generating material excluding nicotine. However, the technical problem to be solved is not limited thereto, and other technical problems may be inferred from the following examples.
- An aerosol-generating article according to one aspect may include a first segment including a first aerosol-generating material that excludes nicotine, and a second segment including a second aerosol-generating material that includes the nicotine, wherein the first aerosol-generating material includes a moisturizing material in an amount of at least 30 mg by weight.
- An aerosol-generating article includes a plurality of segments, and the plurality of segments contain different components and amounts of the aerosol-generating material. Therefore, the satisfactory amount of atomization and the feeling of smoking can be guaranteed for a user. In addition, even if the aerosol-generating article is heated by a single heater, an excellent quality of an aerosol can be generated. In addition, due to a filtering of the aerosol by the portion not heated by a heater, a user can feel a different feeling of smoking compared to a conventional heating-type aerosol-generating article.

second segment 12 may have a length in the range of about 6 mm to 18 mm, but the length not limited thereto. Preferably, the length of thesecond segment 12 may be about 12 mm, but is not limited thereto. - The
third segment 13 may generate a cooling effect of the aerosol. Thus, a user may inhale the cooled aerosol at an appropriate temperature. - For example, the
third segment 13 is made of cellulose acetate, and may be a tube-shaped structure including a hollow inside. For example, thethird segment 13 may be manufactured by adding a plasticizer (e.g., triacetin) to a cellulose acetate tow. For example, the mono denier of thethird segment 13 may be 5.0, and the total denier may be 28,000, but is not limited thereto. - For example, the
third segment 13 is made of paper and may be a tube-shaped structure including a hollow inside. In addition, thethird segment 13 may include at least one hole through which external air may be introduced. - The
third segment 13 may be manufactured by lamination made of several papers. For example, thethird segment 13 may be manufactured by a laminate composed of an outer paper, an intermediate paper, and an inner paper, but is not limited thereto. An inner surface of the inner paper constituting the laminate may be coated with a predetermined material (e.g., polylactic acid). - In a case where the
third segment 13 is made of a paper, the total thickness of thethird segment 13 may be in the range of 330 μm to 340 μm. Preferably, the total thickness of thethird segment 13 may be about 333 μm, but is not limited thereto. - In addition, when the

The length of thethird segment 13 may be within the range of 4 mm to 30 mm, but is not limited thereto. Preferably, the length of thethird segment 13 is about 12 mm, but is not limited thereto. - The
third segment 13 is not limited to the above-described examples, and if thethird segment 13 is capable of performing a function of cooling the aerosol, it may be applicable without limitation. - The
fourth segment 14 may be manufactured by adding a plasticizer (e.g., triacetin) to a cellulose acetate tow. The length of thefourth segment 14 may be within the range of about 4 mm to 30 mm, but is not limited thereto. Preferably, the length of thefourth segment 13 is about 14 mm, but is not limited thereto. - The
fourth segment 14 may be manufactured to generate a flavor. As an example, the flavoring liquid may be sprayed on thefourth segment 14, or a separate fiber coated with the flavoring liquid may be inserted into thefourth segment 14. - In addition, at least one capsule may be included in the
fourth segment 14. Here, the capsule may perform a function of generating a flavor or may perform a function of generating an aerosol. For example, the capsule may have a structure in which a liquid containing perfume is wrapped with a film. The capsule may have a spherical or cylindrical shape, but is not limited thereto. - The aerosol-generating
article 1 may be wrapped by a plurality ofwrappers 15. At least one hole may be formed in the wrappers so that external air flows in or internal gas flows out through the at least one hole. - For example, as shown in
FIG. 1A , thefirst segment 11 is wrapped by afirst wrapper 151, thesecond segment 12 is wrapped by asecond wrapper 152, thethird segment 13 may be wrapped by athird wrapper 153, and thefourth segment 14 may be wrapped by afourth wrapper 154. In addition, the entire aerosol-generatingarticle 1 may be rewrapped by asixth wrapper 156. - Alternatively, as shown in
FIG. 1B , thefirst segment 11 is wrapped by afirst wrapper 151, thesecond segment 12 is wrapped by asecond wrapper 152, thethird segment 13 may be wrapped by athird wrapper 153, and thefourth segment 14 may be wrapped by afourth wrapper 154. In addition, the entire aerosol-generatingarticle 1 may be rewrapped by thesixth wrapper 156. In addition, a part of thethird segment 13 and thefourth segment 14 may be rewrapped by afifth wrapper 155. - The
first wrapper 151 may be formed by bonding a metal foil such as aluminum foil to a general filter wrapper. For example, the total thickness of thefirst wrapper 151 may be in the range of about 40 μm to 80 μm. Preferably, the total thickness of thefirst wrapper 151 is about 64 μm, but is not limited thereto. In addition, the thickness of the metal foil of thefirst wrapper 151 may be in the range of about 10 μm to 30 μm. Preferably, the thickness of the metal foil of thefirst wrapper 151 is about 20 μm, but is not limited thereto. - The total basis weight of the

second wrapper 152 may be formed by bonding a metal foil such as aluminum foil to a general filter wrapper. Thefirst wrapper 151 may have a different thickness and/or basis weight from thesecond wrapper 152. - For example, the thickness of the
second wrapper 152 may be in the range of about 80 μm to 110 μm. Preferably, the total thickness of thesecond wrapper 152 is about 108 pn, but is not limited thereto. In addition, the thickness of the metal foil of thesecond wrapper 152 may be in the range of about 10 um to 30 μm. Preferably, the thickness of the metal foil of thesecond wrapper 152 is about 20 μm, but is not limited thereto. - In addition, the total basis weight of the
second wrapper 152 may be in the range of about 120 g/m2 to 130 g/m2. Preferably, the total basis weight of thesecond wrapper 152 is about 124 g/m2, but is not limited thereto. In addition, the basis weight of the metal foil of thesecond wrapper 152 may be in the range of about 50 g/m2 to 60 g/m2. Preferably, the basis weight of the metal foil of thesecond wrapper 152 is about 54 g/m2, but is not limited thereto. - Meanwhile, the aerosol-generating
article 1 may not include thethird wrapper 153. For example, when thethird segment 13 has a structure including a hollow made of a paper, thethird segment 13 may be wrapped by thesixth wrapper 156 without thethird wrapper 153. - The
fourth wrapper 154 may be made of a wrapper having oil resistance. For example, the thickness of thefourth wrapper 154 may be in the range of about 90 μm to 110 μm. Preferably, the thickness of thefourth wrapper 154 is about 100 μm, but is not limited thereto. In addition, the basis weight of thefourth wrapper 154 may be in the range of about 70 g/m2 to 80 g/m2.

Preferably, the basis weight of thesixth wrapper 156 is about 50 g/m2, but is not limited thereto. In addition, the thickness of thesixth wrapper 156 may be in the range of about 55 μm to 65 μm. Preferably, the thickness of thesixth wrapper 156 is about 61 μm, but is not limited thereto. - In the aerosol-generating
article 1, thefirst segment 11 includes an aerosol-generating material excluding nicotine, and thesecond segment 12 includes an aerosol-generating material including the nicotine. The component and content of the aerosol-generating material included in thefirst segment 11 and the component and content of the aerosol-generating material included in thesecond segment 12 may not be the same. Therefore, in order for a user to have a satisfactory feeling of smoking, thefirst segment 11 and thesecond segment 12 need to be heated to different temperatures. For example, when thesecond segment 12 is heated to a temperature suitable for thefirst segment 11, a user may feel a burnt taste. Alternatively, when thefirst segment 11 is heated to a temperature suitable for thesecond segment 12, sufficient aerosol may not be generated. - As an example, the
first segment 11 and thesecond segment 12 may be heated to different temperatures by different heaters. For example, if thefirst segment 11 is heated to A ° C. by a heater to produce a sufficient amount of aerosol, and thesecond segment 12 is heated to B ° C. by another heater to volatilize an appropriate amount of nicotine, and a user may have a satisfactory feeling of smoking. - As another example, the
first segment 11 and thesecond segment 12 may be heated by a single heater. In this case, it is difficult to heat thefirst segment 11 and thesecond segment 12 to different temperatures. Thus, even if thefirst segment 11 and thesecond segment 12 are heated by one heater, at least one of thewrappers 15 may include a thermally conductive wrapper so that each of thefirst segment 11 and thesecond segment 12 may be heated to an appropriate temperature. An example in which thefirst segment 11 and thesecond segment 12 are heated by a single heater will be described later with reference toFIGS. 3 and 4 . - As described above with reference to
FIGS. 1A and 1B , thefirst segment 11 and thesecond segment 12 may include an aerosol-generating material, and the aerosol-generating material may include a moisturizing material. For example, the moisturizing material may include glycerin, propylene glycol, or a combination thereof, but is not limited thereto. When glycerin and propylene glycol are combined to form a moisturizing material, glycerin and propylene glycol may be combined at a ratio of 8:2. However, the combination ratio is not limited to the example described above. - The moisturizing material included in the
first segment 11 may contribute to the amount of the aerosol produced. In other words, the total amount of atomization of the aerosol-generatingarticle 1 may be determined by the weight of the moisturizing material included in thefirst segment 11. The moisturizing material included in thesecond segment 12 may be involved in the smoking taste of the aerosol-generatingarticle 1. In other words, the smoking taste of the aerosol-generatingarticle 1 may be determined by the nicotine and the moisturizing material included in thesecond segment 12. - In order to generate a sufficient amount of atomization from the aerosol-generating
article 1, thefirst segment 11 must contain a sufficient amount of moisturizing material. In particular, thefirst segment 11 may include a greater amount of moisturizing material than thesecond segment 12. However, when an excessive moisturizing material is included in thefirst segment 11, the moisturizing material may leak out of the aerosol-generatingarticle 1. This is undesirable in view of the appearance of the aerosol-generatingarticle 1. - On the other hand, when a large amount of moisturizing material is included in the
second segment 12, there may be a negative effect on the smoking feeling of the user. For example, as the amount of the moisturizing material included in thesecond segment 12 increases, the amount of heat required for the moisturizing material to vaporize also increases. Accordingly, the amount of vaporization of nicotine and other aerosol-generating materials included in thesecond segment 12 is reduced, and results in a decrease in the satisfaction of a smoking feeling of the user. - Therefore, in order to prevent the appearance of the aerosol-generating
article 1 from degrading and to increase the user's satisfaction of smoking feeling, it is important to properly adjust the weight of the moisturizing material included in thefirst segment 11 and the moisturizing material included in thesecond segment 12. - In particular, the
first segment 11 according to an embodiment includes a moisturizing material in an amount capable of ensuring a sufficient amount of atomization and preventing a change in the appearance of the aerosol-generatingarticle 1. For example, the weight of the moisturizing material included in thefirst segment 11 may be at least 30 mg. Alternatively, the weight of the moisturizing material included in thefirst segment 11 may be at least 40 mg. Alternatively, the weight of the moisturizing material included in thefirst segment 11 may be at least 50 mg. Alternatively, the weight of the moisturizing material included in thefirst segment 11 may be at least 60 mg. Alternatively, the weight of the moisturizing material included in thefirst segment 11 may be less than or equal to 95 wt % of the weight of the sheet impregnated with the moisturizing material. Alternatively, the weight of the moisturizing material included in thefirst segment 11 may be less than or equal to 85 wt % of the weight of the sheet impregnated with the moisturizing material. Alternatively, the weight of the moisturizing material included in thefirst segment 11 may be less than or equal to 75 wt % of the weight of the sheet impregnated with the moisturizing material. - In order to determine the optimal amount of the moisturizing material included in the
first segment 11, the following experiment was conducted. In the experiment below, a sheet made of a paper was impregnated with a moisturizing material, and the weight of the sheet was set to 98 mg. In addition, the moisturizing material was set to be mixed with glycerin and propylene glycol at a ratio of 8:2. Some of the experimental results are illustrated in Table 1 below. -
TABLE 1 Weight of moisturizing Item material TPM Nicotine PG Gly. Moisture 1 40 49.8 1.02 5.41 12.2 20.0 2 59 63.3 1.00 7.78 16.0 24.4 3 78 74.2 1.04 10.2 19.8 28.1 - Table 1 shows the results of analyzing the weight (unit: mg) of components included in the aerosol for each weight (unit: mg) of the moisturizing material included in the
first segment 11. Here, the aerosol means the sum of the aerosols discharged to the outside of the aerosol-generatingarticle 1 by a predetermined number of puffs. Referring to Table 1, it is confirmed that the content of total particulate matter (TPM) in the aerosol varies greatly depending on the content of the moisturizing material in thefirst segment 11. In particular, although the content of PG (propylene glycol), Gly (glycerin) and moisture in the aerosol is different, it is confirmed that the content of nicotine in the aerosol is not significantly different. That is, when the content of the moisturizing material in thefirst segment 11 is more than a certain amount, it may be seen that the effect of nicotine in thesecond segment 12 being discharged to the outside of the aerosol-generatingarticle 1 is small. When the TPM in the aerosol is greater than or equal to about 40 mg, a result similar to the content of nicotine shown in Table 1 was confirmed. In addition, when the content of the moisturizing material in thefirst segment 11 is about 30 mg, it is confirmed that about 40 mg of TPM is contained in the aerosol. That is, when the moisturizing material in thefirst segment 11 is greater than or equal to about 40 mg, it is confirmed that a sufficient amount of atomization is ensured and an adequate amount of nicotine transfer may be ensured. - On the other hand, another experiment was conducted in order to determine the optimized amount of the moisturizing material included in the
first segment 11. The conditions of the experiment are the same as those in the experiment described above with reference to Table 1. Some of the experimental results are as described in Table 2 below. -
TABLE 2 Item 1 2 3 4 Ratio of 75.0 82.5 90.0 97.5 moisturizing material (wt%) Weight of 600 660 720 780 moisturizing material (mg) Results on Good Good Good Leakage leakage - In Table 2, the results of a moisturizing substance leakage from the aerosol-generating
article 1 according to the ratio of the weight of the moisturizing material to the weight of the sheet impregnated with the moisturizing material is shown. Here, leakage may mean that the moisturizing material oozes out of the surface of at least one wrapper surrounding thefirst segment 11. Referring to Table 2, when the ratio of the weight of the moisturizing material to the weight of the sheet impregnated with the moisturizing material is 97.5 wt %, it is confirmed that the moisturizing material leaks. In addition, when the ratio is less than or equal to 90.0 wt %, it is confirmed that no moisturizing material has leaked. In addition, when the ratio of the weight of the moisturizing material to the weight of the sheet impregnated with the moisturizing material is less than or equal to about 95 wt %, it is confirmed that no moisturizing material has leaked. - Also, a moisturizing material may be included in the
second segment 12 according to an exemplary embodiment, and an optimal amount of the moisturizing material is determined to maximize the user's smoking feeling. For example, the weight of the moisturizing material included in thesecond segment 12 may be less than or equal to 30 wt % of the total weight of the aerosol-generating material included in thesecond segment 12. Alternatively, the weight of the moisturizing material included in thesecond segment 12 may be less than or equal to 25 wt % of the total weight of the aerosol-generating material included in thesecond segment 12. Alternatively, the weight of the moisturizing material included in thesecond segment 12 may be less than or equal to 20 wt % of the total weight of the aerosol-generating material included in thesecond segment 12. Alternatively, the weight of the moisturizing material included in thesecond segment 12 may be less than or equal to 15 wt % of the total weight of the aerosol-generating material included in thesecond segment 12. - Hereinafter, an example of the content of the moisturizing material included in the
second segment 12 will be described with reference toFIGS. 2A and 2B . -
FIGS. 2A and 2B are graphs showing heating temperatures of the second segment according to the content of the moisturizing material. - In
FIGS. 2A and 2B , when the content of the moisturizing material in thesecond segment 12 is 3 wt % (A), 10 wt % (B) and 25 wt % (C), graphs showing the relationship between the heating time and temperature of thesecond segment 12 are shown. - Table 3 below shows the total weight of the aerosol-generating material contained in the
second segment 12 and the time taken to reach a specific temperature (e.g., 100° C., 150° C.) when thesecond segment 12 is heated, based on the graph shown inFIG. 2A . -
TABLE 3 Item A B C Ratio of moisturizing 3 10 25 material (wt %) Content of aerosol- 100 170 300 generating material (mg) Time to reach 100° C. 24.1 27.5 45.3 (sec) Time to reach 150° C. 85.6 95.9 152.3 (sec) - In addition, according to the graph shown in
FIG. 2B , Table 4 below summarizes the total weight of the aerosol-generating material contained in thesecond segment 12 and the time taken to reach a specific temperature (e.g., 100° C., 150° C.) when thesecond segment 12 is heated. -
TABLE 4 Item A B C Ratio of moisturizing 3 10 25 material (wt%) Content of aerosol- 100 100 190 generating material (mg) Time to reach 100° C. 24.1 25.6 38.3 (sec) Time to reach 150° C. 85.6 81.1 114.4 (sec) - Comparing the items B and C in Table 3 and the items B and C in Table 4, even if the ratio of the moisturizing material is the same, it is confirmed that the temperature increase rate of the
second segment 12 is high when the total weight of the aerosol-generating material included in thesecond segment 12 decreases. That is, it is confirmed that the temperature increase rate of thesecond segment 12 may be adjusted by controlling the total weight of the aerosol-generating material included in thesecond segment 12. In addition, when the weight of the moisturizing material included in thesecond segment 12 is less than or equal to about 30 wt % of the total weight of the aerosol-generating material included in thesecond segment 12, it is confirmed that the rate of temperature increase of thesecond segment 12 was appropriate. - In addition, the
first segment 11 and thesecond segment 12 may be heated by a single heater. In other words, a single heater may be placed over at least a portion of thefirst segment 11 and at least a portion of thesecond segment 12. Hereinafter, an example in which a single heater is placed over thefirst segment 11 and thesecond segment 12 will be described with reference toFIG. 2B . -
FIG. 3 is a diagram for describing an example of arrangement of a single heater, a first segment, and a second segment. - The aerosol-generating
article 1 may include afirst segment 11 and asecond segment 12 including materials of different compositions in order to produce an abundant amount of aerosol, as well as to transport nicotine and tobacco flavor. For example, thefirst segment 11 may contain only an aerosol-generating material excluding nicotine to generate an aerosol in an abundant amount. In addition, thesecond segment 12 may include not only an aerosol-generating material, but also nicotine for transporting tobacco flavor. In addition, the more the moisturizing material is included, the larger the amount of aerosol is generated. Therefore, thefirst segment 11 may contain a larger amount of the moisturizing material than thesecond segment 12. - The
first segment 11 and thesecond segment 12 according to an embodiment may be heated by asingle heater 410. For example, thesingle heater 410 may heat a first portion d1 of thefirst segment 11 and a second portion d2 of the second segment. In this case, the area of the first portion d1 and the area of the second portion d2 may be the same. - In
FIG. 3 , a cross section of thesingle heater 410 is shown, however, thesingle heater 410 may be configured to surround thefirst segment 11 and thesecond segment 12. Therefore, when the lengths of the first portion d1 and the second portion d2 are the same, the area of thefirst segment 11 and the area of thesecond segment 12, wrapped by thesingle heater 410 are also the same. - The
single heater 410 may directly contact thefirst segment 11 and thesecond segment 12, and may indirectly contact thefirst segment 11 and thesecond segment 12 through other configurations. For example, thesingle heater 410 may indirectly contact thefirst segment 11 or thesecond segment 12 through a thermally conductive wrapper or thermally conductive tube, and a heating temperature difference between thefirst segment 11 and thesecond segment 12 may be realized by indirect heating method through the thermally conductive wrapper or the thermally conductive tube. On the other hand, it was confirmed that when the heating temperature of thesingle heater 410 is greater than or equal to about 120° C., the user's smoking feeling may be satisfied. - The portion of the
second segment 12 that is not heated may perform a function of filtering an aerosol. In other words, an aerosol generated by thesingle heater 410 may be filtered by the remaining portions of thesecond segment 12 other than the second portion d2. Hereinafter, an example in which aerosol is filtered will be described with reference toFIG. 4 . -
FIG. 4 is a diagram for describing an example in which an aerosol is filtered by at least a portion of a second segment. -
FIG. 4 shows an example of an aerosol-generatingarticle 1. In particular, thesecond segment 12 may be divided into aportion 121 heated by a heater and aportion 122 that is not heated by the heater. - As at least a
portion 121 of thefirst segment 11 and at least aportion 122 of thesecond segment 12 are heated by the heater, an aerosol is generated. The generated aerosol moves along the downstream of the aerosol-generatingarticle 1 and is finally delivered to the user. In this case, as the generated aerosol passes through theportion 122 of thesecond segment 12 that is not heated, some materials may be filtered. Here, filtering not only filters some of the components included in the aerosol, but may also filter other components contained in the aerosol. - That is, the
portion 122 that is not heated may cause changes in the components in the aerosol. For example, as the aerosol passes through theunheated portion 122, some components in the aerosol may be filtered out, and some components included in theunheated portion 122 may be further included in the aerosol. Accordingly, the aerosol discharged to the outside of the aerosol-generatingarticle 1 may be different from the component of the aerosol initially generated. Thus, compared to thesecond segment 12 being entirely heated, a user may feel a different feeling of smoking. - Those of ordinary skill in the art may understand that various changes in form and details can be made therein without departing from the scope of the embodiments described above. The embodiments should be considered in a descriptive sense, and should not be construed as limiting the embodiments of the disclosure. The scope of the present disclosure is defined by the appended claims, and any modifications, substitutions and equivalents thereof should be construed as falling within the scope of the present disclosure.
