Therefore, the terms used in the various embodiments of the present disclosure should be defined based on the meaning of the terms and the description provided herein.

[0025] In addition, unless explicitly described to the contrary, the term "include" and variations such as "include" or "includes" will be understood to mean including the stated elements but not excluding any other elements. In addition, the terms "-component", "-device" and "module" described in the application documents refer to units for processing at least one function and operation, and can be implemented by hardware components or software components and combinations thereof.

[0026] As used herein, when a statement such as "at least any one" is placed after an element of an arrangement, the statement modifies all elements rather than each element of the arrangement. For example, the statement "at least any one of a, b, and c" should be interpreted as: including a, including b, including c, or including a and b, including a and c, including b and c, or including a, b, and c.

[0027] In an embodiment, the aerosol generating device may be a device that generates aerosol by electrically heating a cigarette accommodated in an internal space of the aerosol generating device.

[0028] The aerosol generating device may comprise a heater. In an embodiment, the heater may be a resistive heater. For example, the heater may comprise a conductive trace, and the heater may be heated when an electric current flows through the conductive trace.

[0029] The heater may include a tubular heating element, a plate heating element, a needle heating element or a rod heating element, and the heater may heat the inside or outside of the cigarette depending on the shape of the heating element.

The cartridge may be formed integrally with the main body or assembled with the main body, and the cartridge may also be fixed to the main body without being removed from the main body by the user. The cartridge may be mounted on the main body while the aerosol generating substance is contained in the cartridge. However, the present disclosure is not limited thereto. When the cartridge is connected to the main body, the aerosol generating substance may also be injected into the cartridge.

[0034] The cartridge may contain an aerosol-generating substance in any of various states such as liquid, solid, gaseous, gel, etc. The aerosol-generating substance may include a liquid composition. For example, the liquid composition may be: a liquid containing a tobacco substance having a volatile tobacco flavor component; or a liquid containing a non-tobacco substance.

[0035] The cartridge can be operated by an electrical signal or a wireless signal transmitted from the main body to perform the function of generating an aerosol by converting the phase of the aerosol-generating substance in the cartridge into a gas phase. Aerosol may refer to a gas of vaporized particles generated by the aerosol-generating substance mixed with air.

The aerosol-generating substance absorbed in the core may be converted into a gas phase by the heat and / or ultrasonic vibration transferred from the vibrator, and thus an aerosol may be generated.

[0041] For example, the viscosity of the aerosol generating substance absorbed in the core may be reduced by heat generated by the vibrator, and when the aerosol generating substance having the reduced viscosity is granulated by ultrasonic vibration generated by the vibrator, aerosol may be generated, but is not limited thereto.

[0042] In another embodiment, the aerosol generating device is a device that generates an aerosol by heating an aerosol generating article housed in the aerosol generating device by induction heating.

Although the drawings show an embodiment in which the cross section of the housing 120 is formed in a semicircular shape as a whole, the shape of the housing 120 is not limited thereto. According to an embodiment (not shown), the housing 120 may be formed in a cylindrical shape or a polygonal prism (e.g., a triangular prism or a quadrangular prism) shape as a whole.

[0051] In one embodiment, components for generating aerosol by heating the aerosol generating article 110 inserted into the housing 120 and components of a screen for outputting the state of the aerosol generating device 100 may be arranged in the internal space of the housing 120, and a detailed description of these components is given below.

At least a portion of the aerosol generating article 110 may be inserted into or accommodated in the housing 120 through the opening 100h.

[0053] Aerosol may be generated when the aerosol generating article 110 inserted into the housing 120 or housed in the housing 120 is heated within the housing 120. The generated aerosol may be discharged to the outside of the aerosol generating device 100 through the inserted aerosol generating article 110 and / or a space between the aerosol generating article 110 and the opening 100h, and the user may inhale the discharged aerosol.

The information displayed on the display 130 is an example and is not limited to the above-mentioned embodiments.

[0059] Figure 2 is an enlarged view of some components of an aerosol generating system according to an embodiment.

[0060] Reference Figure 2 According to an embodiment, an aerosol generating system 1000 may include an aerosol generating article 110 and an aerosol generating device 100, wherein the aerosol generating device 100 includes a housing 120 (eg, Figure 1 The components of the aerosol generating system 1000 according to the embodiment may be connected to Figure 1 At least one of the components of the aerosol generating system 1000 shown in FIG. 1 is substantially the same or similar, and redundant descriptions of these components are omitted below.

[0061] The heating element 200 can generate an aerosol by heating the aerosol generating article 110 inserted into the housing 120 through the opening 100h or accommodated in the housing 120. The heating element 200 can heat the aerosol generating article 110, for example, by generating heat using the received electric power. In this case, the aerosol can be generated by mixing vaporized particles generated by heating the aerosol generating article 110 with air introduced into the housing 120 through the opening 100h.

[0062] According to one embodiment, the heating element 200 may include an induction heating type heater. For example, the heating element 200 may include a coil 201 (or "conductive coil") and a susceptor 202, the coil 201 being used to provide a magnetic field that changes according to the supplied power, the susceptor 202 generating heat by the changing magnetic field generated by the coil 201, and the heating element 200 may heat the aerosol generating article 110 accommodated in the housing 120 by using an induction heating method.

[0063] When the aerosol-generating article 110 is accommodated in the housing 120, the susceptor 202 is arranged to surround at least a portion of the outer peripheral surface of the aerosol-generating article 110 to heat the aerosol-generating article 110 accommodated in the housing 120. The susceptor 202 can generate heat by, for example, an alternating magnetic field generated by the coil 201, and thus, the aerosol-generating article 110 can be heated.

[0064] According to one example, the receptor 202 may be arranged to surround at least a portion of the outer peripheral surface of the medium portion of the aerosol generating article 110 including the aerosol generating substance, and the coil 201 may be arranged to surround at least a portion of the outer peripheral surface of the receptor 202, and thus, the aerosol generating article 110 housed in the shell 120 may generate an aerosol by heating.

[0065] According to another embodiment, the heating element 200 may include a resistive heater. For example, the heating element 200 may include a film heater arranged to cover at least a portion of the outer peripheral surface of the aerosol generating article 110 housed in the housing 120. The film heater may include conductive traces, and as current flows through the conductive traces, the film heater may generate heat to heat the aerosol generating article 110 inserted into the housing 120.

[0067] The heating element 200 is not limited to the above-described embodiment, and the embodiment of the heating element 200 may be modified as long as the aerosol generating article 110 can be heated to a specified temperature. In the present disclosure, "specified temperature" may refer to a temperature at which an aerosol generating substance included in the aerosol generating article 110 can be heated to generate an aerosol. The specified temperature may be a temperature preset in the aerosol generating device 100, but the corresponding temperature may be changed according to the type of the aerosol generating device 100 and / or the operation of the user.

Since the supporting portion 204 supports the aerosol generating article 110 and the heating element 200 so that the aerosol generating article 110 and the heating element 200 have different heights from the bottom surface of the housing 120 in the +z-axis direction, the heating element 200 can heat a desired area of ​​the aerosol generating article 110.

[0072] The heat insulating structure 256 may be arranged around the outer peripheral surface of the heating element 200 to prevent the heat generated from the heating element 200 from being discharged to the outside, and thus, the ambient temperature of the heating element 200 may be maintained at a high temperature. In addition, the heat insulating structure 256 may seal the heating element 200 to prevent droplets generated during the aerosol generation process from leaking out.

[0073] According to one embodiment, the thermal insulation structure 256 may be arranged to surround an area (e.g., bottom surface and / or side surface) of the outer peripheral surface of the heating element 200.

[0075] In one example, the second thermal insulation structure 206 may include a vacuum insulation layer and may vacuum-insulate the susceptor 202, but is not limited thereto. In another example, the second thermal insulation structure 206 may be coupled to at least one region of the lower end of the first thermal insulation structure 205, or the first thermal insulation structure 205 and the second thermal insulation structure 206 may be integrally formed.

For example, the length E of the cooling portion 640 may be appropriately selected within the range of about 10 mm to about 14 mm. Preferably, the length E of the cooling portion 640 may be about 12 mm, but is not limited thereto. The diameter of the cooling portion 640 may be appropriately selected within the range of about 7 mm to about 7.4 mm, but is not limited thereto. Preferably, the diameter of the cooling portion 640 may be about 7.2 mm, but is not limited thereto.

[0102] The length F of the filter portion 650 may be appropriately selected within the range of about 12 mm to about 16 mm, but is not limited thereto. Preferably, the length F of the filter portion 650 may be about 14 mm, but is not limited thereto. The diameter of the filter portion 650 may be appropriately selected within the range of about 7 mm to about 7.4 mm, but is not limited thereto. Preferably, the diameter of the filter portion 650 may be about 7.2 mm, but is not limited thereto.

[0103] The susceptor 602 may be arranged to surround at least a portion of the second dielectric portion 620 and a portion of the first dielectric portion 630, and the susceptor 602 may be provided by a coil (eg, Figure 2 The alternating magnetic field generated by the coil 201) is used to generate heat to heat at least some areas of the second dielectric portion 620 and the first dielectric portion 630.

[0104] exist Figure 6 , the total length of the susceptor 602 may be represented as B + C. In this case, the length of the susceptor 602 arranged to surround the outer peripheral surface of the second dielectric portion 620 to heat the second dielectric portion 620 is represented as B, and the length of the susceptor 602 arranged to surround the outer peripheral surface of the first dielectric portion 630 to heat the first dielectric portion 630 is represented as C.

[0105] The total length B+C of the susceptor 602 may be appropriately selected within the range of about 12 mm to about 16 mm, but is not limited thereto. Preferably, the total length B+C of the susceptor 602 may be approximately 14 mm, but is not limited thereto. The diameter of the susceptor 602 may be appropriately selected within the range of about 7 mm to about 7.4 mm, but is not limited thereto. Preferably, the diameter of the susceptor 602 may be approximately 7.27 mm, but is not limited thereto.

[0106] In the aerosol generating system 1000 according to the embodiment, the area of ​​the outer circumferential surface of the first medium portion 630 and the second medium portion 620 surrounded by the susceptor 602 and / or the area of ​​the outer circumferential surface of the susceptor 602 surrounded by the coil may be various. The quality of the generated aerosol may be changed according to the area or position of the outer circumferential surface of the first medium portion 630 and the second medium portion 620 surrounded by the susceptor 602 and / or the area or position of the outer circumferential surface of the susceptor 602 surrounded by the coil. In the present disclosure, "the quality of the aerosol" may refer to the amount of the generated aerosol and / or the inhalation resistance that the user can feel when inhaling the aerosol, and the expression may be used with the same meaning below.

[0107] In the aerosol generating system 1000 according to the embodiment, a partial area of ​​the outer peripheral surface of the first medium portion 630 and a partial area of ​​the outer peripheral surface of the second medium portion 620 may be arranged to be surrounded by one susceptor 602 and one coil. Since the aerosol generating article is heated by using one susceptor 602 and one coil, the structure of the aerosol generating device may be simplified and the weight of the aerosol generating device may be reduced.

[0108] The inhalation resistance may refer to the force with which a user inhales aerosol when smoking, and in order to provide a stable smoking feeling to the user experimentally, the size of the inhalation resistance needs to be maintained at about 6 mmWG.

[0109] In the aerosol generating system 1000 according to the embodiment, the inhalation resistance can be adjusted by setting the length C of the first medium portion 630 whose outer peripheral surface is surrounded by the receptor 602 and the length B of the second medium portion 620 whose outer peripheral surface is surrounded by the receptor 602 in different ways, and thus, the inhalation resistance that can improve the user's smoking sensation can be maintained.

[0110] For example, as the area of ​​the first media portion 630 heated by the susceptor 602 increases, the pores in the first media portion 630 may expand, and thus, the magnitude of the suction resistance may decrease. In addition, as the area of ​​the second media portion 620 heated by the susceptor 602 decreases, the heat transferred to the first media portion 630 decreases, and thus, the pores in the first media portion 630 may decrease, and thus, the magnitude of the suction resistance may increase.

[0111] That is, when the length C of the first medium portion 630 whose outer peripheral surface is surrounded by the sensor 602 is greater than the length B of the second medium portion 620 whose outer peripheral surface is surrounded by the sensor 602, the magnitude of the suction resistance can be reduced, but when the length B of the second medium portion 620 whose outer peripheral surface is surrounded by the sensor 602 is reduced too much, the magnitude of the suction resistance may increase instead.

[0112] Therefore, in the aerosol generating system 1000 according to the embodiment, by adjusting the ratio of the length C of the first medium portion 630 whose outer peripheral surface is surrounded by the receptor 602 and the length B of the second medium portion 620 whose outer peripheral surface is surrounded by the receptor 602, an inhalation resistance for providing the user with an optimal smoking experience can be achieved.

[0113] For example, in the aerosol generating system 1000 according to the embodiment, by adjusting the ratio of the length C of the first medium portion 630 whose outer peripheral surface is surrounded by the receptor 602 to the length B of the second medium portion 620 whose outer peripheral surface is surrounded by the receptor 602, the size of the inhalation resistance can be maintained at about 6 mmWG to provide an optimal smoking experience.

[0114] Hereinafter, changes in suction resistance according to a ratio of a length C of a first medium portion 630 whose outer peripheral surface is surrounded by the susceptor 602 to a length B of a second medium portion 620 whose outer peripheral surface is surrounded by the susceptor 602 are described with reference to Table 1.

[0115] In Table 1, Example 1 shows that the length C of the first dielectric portion 630 whose outer peripheral surface is surrounded by the susceptor 602 is 7 mm, the length B of the second dielectric portion 620 whose outer peripheral surface is surrounded by the susceptor 602 is 7 mm, and the ratio of the length C of the first dielectric portion 630 whose outer peripheral surface is surrounded by the susceptor 602 to the length B of the second dielectric portion 620 whose outer peripheral surface is surrounded by the susceptor 602 is 1:1.

[0116] In addition, Example 2 shows that the length C of the first dielectric portion 630 is 8 mm, the length B of the second dielectric portion 620 whose outer peripheral surface is surrounded by the susceptor 602 is 7 mm, and the ratio of the length C of the first dielectric portion 630 whose outer peripheral surface is surrounded by the susceptor 602 to the length B of the second dielectric portion 620 whose outer peripheral surface is surrounded by the susceptor 602 is 1.3:1.

[0117] In addition, Example 3 shows that the length C is 9 mm, the length B of the second dielectric portion 620 whose outer peripheral surface is surrounded by the susceptor 602 is 5 mm, and the ratio of the length C of the first dielectric portion 630 whose outer peripheral surface is surrounded by the susceptor 602 to the length B of the second dielectric portion 620 whose outer peripheral surface is surrounded by the susceptor 602 is 1.8:1.

[0118] Experimental Example 1: Inhalation resistance measurement experiment

[0119] 150 (100%) aerosol generating systems 1000 arranged as in Examples 1 to 3 were prepared, and aerosols were generated to measure the inhalation resistance (mmWG) generated when a user inhaled the generated aerosols. The measurement results are as follows.

[0120] In the aerosol generating system 1000 of Example 1, one inhalation resistance (0.7%) was measured as 5 mmWG, 42 inhalation resistances (28.0%) were measured as 6 mmWG, 107 inhalation resistances (71.3%) were measured as 7 mmWG, and the average resistance was measured as 6.71 mmWG. In the aerosol generating system 1000 of Example 2, 4 inhalation resistances (2.7%) were measured as 5 mmWG, 119 inhalation resistances (79.3%) were measured as 6 mmWG, 27 inhalation resistances (19.0%) were measured as 7 mmWG, and the average resistance was measured as 6.15 mmWG. In the aerosol generating system 1000 of Example 3, 3 inhalation resistances (2.0%) were measured at 5 mmWG, 62 inhalation resistances (41.3%) were measured at 6 mmWG, 85 inhalation resistances (56.7%) were measured at 7 mmWG, and the average resistance was measured at 6.57 mmWG. The measured inhalation resistances are shown in Table 1 below.

[0121]

Table 1

[0122]

[0123] Referring to Table 1, it can be seen that in the aerosol generating system 1000 according to the embodiment, when the ratio of the length C of the first medium portion 630 whose outer peripheral surface is surrounded by the susceptor 602 to the length B of the second medium portion 620 whose outer peripheral surface is surrounded by the susceptor 602 is less than 1:1 or greater than 1.8:1, as described above, the magnitude of the inhalation resistance increases. Therefore, it can be seen that in the range of 1:1 to 1.8:1, the inhalation resistance for providing the user with the best smoking experience can be achieved, and in particular, when the ratio is 1.4:1, an inhalation resistance of about 6.15 mmWG can be achieved.

[0124] The aerosol generating system 1000 can generate multiple aerosols from a single aerosol generating article. For example, in the aerosol generating system 1000, the amount of atomization generated when a user performs multiple puffs on an aerosol generating article may not be constant. The smaller the deviation of the amount of atomization generated when performing multiple puffs, the more the continuity of the aerosol generating system 1000 can be increased.

[0125] The aerosol generating system 1000 according to an embodiment may include an area where the susceptor 602 surrounds the outer peripheral surface of the first medium portion 630 and an area where the susceptor 602 does not surround the outer peripheral surface of the first medium portion 630. For example, the ratio between the two areas can be expressed as a ratio of a length C of the first medium portion 630 whose outer peripheral surface is surrounded by the susceptor 602 to a length D of the first medium portion 630 whose outer peripheral surface is not surrounded by the susceptor 602.

[0126] In the aerosol generating system 1000 according to the embodiment, when an initial puff action (e.g., 1 to 7 puff actions) is performed, the first area (e.g., Figure 6 aerosol is generated in the region C of the first medium portion 630, and when subsequent puffs are performed (e.g., 8 to 14 puffs), a second region (e.g., Figure 6 For example, during the initial puffing action, the aerosol may be generated mainly from the first area of ​​the first medium portion 630 that is directly heated by the susceptor 602, and, in the subsequent puffing action, the aerosol may be generated mainly from the second area of ​​the first medium portion 630 due to the heat conducted by the susceptor 602.

[0127] Since the length C of the first medium portion 630 whose outer peripheral surface is surrounded by the susceptor 602 is long, the amount of aerosol generated initially may be sufficient. In addition, as the length D of the first medium portion 630 whose outer peripheral surface is not surrounded by the susceptor 602 decreases, the amount of aerosol generated subsequently may decrease. That is, in the aerosol generating system 1000, the continuity of the amount of atomization provided to the user may be changed according to the ratio of the length C of the first medium portion 630 whose outer peripheral surface is surrounded by the susceptor 602 to the length D of the first medium portion 630 whose outer peripheral surface is not surrounded by the susceptor 602.

[0128] Since the amount of atomization is continuously generated during multiple puffing actions, a better smoking experience can be provided to the user. By adjusting the ratio of the length C of the first medium portion 630 whose outer peripheral surface is surrounded by the susceptor 602 to the length D of the first medium portion 630 whose outer peripheral surface is not surrounded by the susceptor 602, a uniform amount of atomization can be provided to the user during the puffing action. For example, by adjusting the ratio of the length C of the first medium portion 630 whose outer peripheral surface is surrounded by the susceptor 602 to the length D of the first medium portion 630 whose outer peripheral surface is not surrounded by the susceptor 602, the deviation of the amount of atomization generated during the puffing action can be greatly reduced.

[0129] According to an embodiment, the aerosol generating system 1000 can heat an aerosol generating article including a first medium part 630 and a second medium part 620 by using a receptor 602 and a coil. The receptor 602 can be arranged to surround only some areas of the first medium part 630 and the second medium part 620, and by adjusting the ratio of the length C of the first medium part 630 whose outer peripheral surface is surrounded by the receptor 602 to the length D of the first medium part 630 whose outer peripheral surface is not surrounded by the receptor 602, the amount of atomization can be continuously generated without providing additional components.

[0130] In order to heat the first medium portion 630 and the second medium portion 620 to a desired temperature or generate a desired amount of atomization, a susceptor 602 or a coil may be additionally arranged. However, the aerosol generating system 1000 can achieve structural simplification and lightweighting of the device while continuously generating an optimal amount of atomization without additionally arranging a susceptor 602 or a coil by adjusting the ratio of the length C of the first medium portion 630 whose outer peripheral surface is surrounded by the susceptor 602 to the length D of the first medium portion 630 whose outer peripheral surface is not surrounded by the susceptor 602.

[0131] Hereinafter, with reference to Table 2, the uniformity of the amount of atomization according to the ratio of the length C of the first medium portion 630 whose outer peripheral surface is surrounded by the susceptor 602 to the length D of the first medium portion 630 whose outer peripheral surface is not surrounded by the susceptor 602 during the suction action is described.

[0132] Examples 1 to 3 in Table 2 used the same aerosol-generating articles as those of Examples 1 to 3 in Table 1, and redundant descriptions of these aerosol-generating articles are omitted below.

[0133] Experimental Example 2: Atomization Continuity Evaluation Experiment

[0134] The aerosol generating system 1000 arranged as in Examples 1 to 3 was operated for a total of 14 puffs, and the amount of aerosol generated per puff was measured. It was assumed that the user inhaled 55cc of aerosol in 1.5 seconds per puff. The measurement results are as follows.

[0135] Fig. 7A is a graph showing relative changes in atomization amount of a puff action according to the aerosol generating system of Example 1. In the aerosol generating system 1000 of Example 1, the maximum value of atomization amount generated is 1.2, the minimum value of atomization amount generated is 0.50, and the deviation is 0.70. Figure 7B is a graph showing relative changes in atomization amount of a puff action according to the aerosol generating system of Example 2. In the aerosol generating system 1000 of Example 2, the maximum value of atomization amount generated is 0.99, the minimum value of atomization amount generated is 0.60, and the deviation is 0.39. Figure 7C is a graph showing the relative change of the atomization amount according to the puff action of the aerosol generating system of Example 3. In the aerosol generating system 1000 of Example 3, the maximum value of the atomization amount generated is 1.0, the minimum value of the atomization amount generated is 0.50, and the deviation is 0.50. The measured atomization amount is shown in Table 2 below.

[0136]

Table 2

[0137] Maximum Minimum deviation Example 1 1.2 0.50 0.70 Example 2 0.99 0.60 0.39 Example 3 1.0 0.50 0.50

[0138] Referring to Table 2, it can be seen that in the aerosol generating system 1000 according to the embodiment, when the ratio of the length C of the first medium portion 630 whose outer peripheral surface is surrounded by the susceptor 602 to the length D of the first medium portion 630 whose outer peripheral surface is not surrounded by the susceptor 602 is less than 1.4:1 or greater than 3:1, as described above, the deviation between the maximum value and the minimum value of the generated atomization amount increases. Therefore, it can be seen that in the range of 1.4:1 to 3:1, the atomization amount for providing the user with the best smoking experience can be continuously provided to the user, and in particular, when the ratio is 2:1, the atomization amount with the minimum deviation can be continuously provided to the user during the puffing action.

[0139] Referring to Tables 1 and 2, in an aerosol generating system 1000 according to an embodiment, in order to achieve optimal inhalation resistance and generate a constant amount of atomization from an aerosol generating product while performing multiple puffing actions, the ratio of the length C of the first medium portion 630 whose outer peripheral surface is surrounded by the receptor 602 to the length B of the second medium portion 620 whose outer peripheral surface is surrounded by the receptor 602 can be in the range of 1:1 to 1.8:1, or preferably 1.4:1, and the ratio of the length C of the first medium portion 630 whose outer peripheral surface is surrounded by the receptor 602 to the length D of the first medium portion 630 whose outer peripheral surface is not surrounded by the receptor 602 can be in the range of 1.4:1 to 3:1, or preferably 2:1.

[0140] Therefore, the ratio of the length B of the second media portion 620 whose outer peripheral surface is surrounded by the susceptor 602 to the length A of the second media portion 620 whose outer peripheral surface is not surrounded by the susceptor 602 may be in the range of 1:1 to 2.3:1, preferably 2:3.

[0141] Mainstream smoke may refer to smoke inhaled into the user's mouth when the user smokes, and the temperature of the mainstream smoke needs to be maintained at about 50° C. to provide the user with the best smoking experience.

[0142] The aerosol generating system 1000 according to the embodiment can maintain the temperature of the mainstream smoke capable of increasing the smoking sensation of the user by adjusting the ratio of the length C of the first medium portion 630 whose outer peripheral surface is surrounded by the susceptor 602 to the length E of the cooling portion 640 .

[0143] The temperature of the mainstream smoke may be affected by the degree to which the first media portion 630 is heated, and may increase as the length C of the first media portion 630 whose outer peripheral surface is surrounded by the susceptor 602 increases. In addition, as the length E of the cooling portion 640 increases, the temperature of the mainstream smoke may decrease.

[0144] For example, the aerosol generating system 1000 according to the embodiment can maintain the temperature of the mainstream smoke at 50° C. by adjusting the ratio of the length C of the first medium portion 630 whose peripheral surface is surrounded by the susceptor 602 to the length E of the cooling portion 640 to provide an optimal smoking experience.

[0145] Hereinafter, the following is described by referring to Table 3: The temperature of mainstream smoke varies according to the ratio of the length C of the first medium portion 630 whose outer peripheral surface is surrounded by the susceptor 602 to the length E of the cooling portion 640 .

[0146] Examples 1 to 3 in Table 3 used the same aerosol-generating articles as those of Examples 1 to 3 in Table 1, and redundant descriptions of these aerosol-generating articles are omitted below.

[0147] Experimental Example 3: Temperature measurement experiment of mainstream smoke

[0148] Ten aerosol generating systems 1000 arranged as in Examples 1 to 3 were prepared and aerosol was generated to measure the temperature (° C.) of the generated mainstream smoke. The measurement results are as follows.

[0149] In the aerosol generating system 1000 of Example 1, the minimum temperature of the mainstream smoke was measured to be 61.4°C, the maximum temperature of the mainstream smoke was measured to be 67.3°C, and the average temperature was measured to be 64.1°C. In the aerosol generating system 1000 of Example 2, the minimum temperature of the mainstream smoke was measured to be 62.2°C, the maximum temperature of the mainstream smoke was measured to be 68.1°C, and the average temperature was measured to be 64.4°C. In the aerosol generating system 1000 of Example 3, the minimum temperature of the mainstream smoke was measured to be 66.8°C, the maximum temperature of the mainstream smoke was measured to be 69.5°C, and the average temperature was measured to be 65.4°C. The measured temperatures of the mainstream smoke are shown in Table 3 below.

[0150]

Table 3

[0151]

[0152] Referring to Table 3, it can be seen that in the aerosol generating system 1000 according to the embodiment, as the length C of the first medium portion 630 whose outer peripheral surface is surrounded by the susceptor 602 increases, as described above, the temperature of the mainstream smoke increases. Therefore, it can be seen that in the aerosol generating system 1000 according to the embodiment, in the range of 1.3:1 to 1.7:1 of the ratio of the length E of the cooling portion 640 to the length C of the first medium portion 630 whose outer peripheral surface is surrounded by the susceptor 602, the user can be provided with mainstream smoke of an optimal temperature while achieving an optimal inhalation resistance and continuously generating a smoke amount, and in particular, when the ratio is 1.5:1, the deviation of the smoke amount generated during the puffing action can be greatly reduced, and the temperature of the mainstream smoke can be maintained at about 50°C while maintaining the size of the inhalation resistance to about 6 mmWG.

[0153] Figure 8 is a diagram showing an aerosol generating system according to an embodiment.

[0154] Reference Figure 8According to an embodiment, the aerosol generating system 1000 may further include a sensor 810 and a processor 1010. According to an example, the sensor 810 may be electrically connected to the processor 1010 or operatively connected to the processor 1010, and the sensor 810 may be arranged adjacent to the opening 100h of the housing 120 to detect the type of the aerosol generating article 110 accommodated in the opening 100h and / or detect whether the aerosol generating article 110 is accommodated.

[0155] According to another example, the sensor 810 may detect an inductance value inside the housing 120, which corresponds to the type of the aerosol generating article 110 accommodated in the opening 100h and / or whether the aerosol generating article 110 is accommodated or removed. The processor 1010 may obtain the inductance value corresponding to the type of the aerosol generating article 110 and / or whether the aerosol generating article 110 is accommodated or removed through the sensor 810, and the processor 1010 may detect the type of the aerosol generating article 110 accommodated in the opening 100h and / or whether the aerosol generating article 110 is accommodated or removed based on the obtained inductance value.

[0156] In the aerosol generating system 1000 according to another embodiment, the processor 1010 may detect whether the aerosol generating article 110 is accommodated in the opening 100h through the sensor 810. For example, the processor 1010 may detect whether the aerosol generating article 110 is accommodated in the opening 100h or removed from the opening 100h through the sensor 810.

[0157] Although not shown, the aerosol-generating article 110 may include a thermally conductive film therein. Thus, when the aerosol-generating article 110 is received in or removed from the opening 100h, electrical characteristics in the housing 120 may change.

[0158] The processor 1010 may detect changes in electrical characteristics in the housing 120 through the sensor 810 , and may detect whether the aerosol generating article 110 is accommodated in the opening 100h or removed from the opening 100h based on the detection result.

[0159] In an aerosol generating system 1000 according to another embodiment, the processor 1010 may detect the type of the aerosol generating article 110 accommodated in the opening 100h through the sensor 810. For example, the processor 1010 may detect whether the aerosol generating article 110 accommodated in the opening 100h is Figure 3A and Figure 3B Aerosol-generating products, Figure 4A and Figure 4B Aerosol-generating products or Figure 5A and Figure 5B Aerosol-generating products are tested.

[0160] Since the aerosol generating article 110 includes a thermally conductive film therein, when the aerosol generating article 110 is accommodated in the opening 100h, the electrical characteristics in the housing 120 may change. The size, shape, material, etc. of the thermally conductive film included in the aerosol generating article 110 may change according to the type of the aerosol generating article 110, and therefore, the electrical characteristics in the housing 120 may change according to the type of the aerosol generating article 110 accommodated in the opening 100h.

[0161] The processor 1010 may detect changes in electrical characteristics in the housing 120 through the sensor 810 , and detect the type of the aerosol generating article 110 accommodated in the opening 100h based on the detection result.

[0162] Fig. 9 is a flow chart showing an operating method of an aerosol generating device according to an embodiment. Fig. 9 When describing the method of operation of the aerosol generating device shown in Figure 1 and / or Figure 8 A description is given of the components of the aerosol generating system 1000 shown in FIG.

[0163] Reference Fig. 9 In operation 910, the aerosol generating device of the aerosol generating system 1000 according to the embodiment may determine whether the aerosol generating article 110 is accommodated through the sensor 810. When the aerosol generating article 110 is accommodated in the internal space through the opening 100h, the processor 1010 may detect a change in the electrical characteristics in the housing 120 through the sensor 810, and detect whether the aerosol generating article 110 is accommodated in the housing 120 based on the detection result.

[0164] In operation 920 , when it is determined that the aerosol generating article 110 is accommodated in the accommodation space through the opening 100h , operation 930 may be performed, and when it is determined that the aerosol generating article 110 is not accommodated in the accommodation space, the aerosol generating system 1000 may stop processing without operating.

[0165] When it is determined in operation 920 that the aerosol generating article 110 is accommodated in the housing 120, the aerosol generating device of the aerosol generating system 1000 may detect the type of the aerosol generating article 110 accommodated in the accommodation space of the housing 120 through the inductive sensor included in the sensor 810 in operation 930. The processor 1010 may detect the change of the electrical characteristics in the housing 120, which are different according to the type of the aerosol generating article 110 accommodated in the internal space through the opening 100h, through the sensor 810, and detect the type of the accommodated aerosol generating article 110 based on the detection result. For example, the processor 1010 may detect whether the accommodated aerosol generating article 110 is Figure 3A and Figure 3B Aerosol-generating products, Figure 4A and Figure 4B aerosol generating products or Figure 5A and Figure 5B Aerosol-generating products are tested.

[0166] In operation 940, the aerosol generating device of the aerosol generating system 1000 may control the power supplied to the heating element 200 according to the type of the aerosol generating article 110 detected in operation 930. The processor 1010 may supply power to the heating element when a first aerosol generating article is accommodated in the accommodation space so that the heating element is heated according to a first temperature curve, and the processor 1010 may supply power to the heating element when a second aerosol generating article different from the first aerosol generating article is accommodated in the accommodation space so that the heating element is heated according to a second temperature curve. Figure 3A and Figure 3B The temperature curve corresponding to the aerosol generating article 110 can be input by the user or preset in the aerosol generating system 1000, and when it is determined Figure 3A and Figure 3B When the aerosol-generating article 110 is accommodated, the processor 1010 may control the power supplied to the coil so that the susceptor 602 generates heat according to the temperature curve.

[0167] Fig.10 is a block diagram of an aerosol generating device 100 according to another embodiment.

[0168] The aerosol generating device 100 may include a controller 1010, a sensing unit 1020, an output unit 1030, a battery 1040, a heater 1050, a user input unit 1060, a memory 1070, and a communication unit 1080. However, the internal structure of the aerosol generating device 100 is not limited to Fig.10That is, according to the design of the aerosol generating device 100, a person skilled in the art will understand that: Fig.10 Some of the components shown in FIG. 1 may be omitted, or new components may be added.

[0169] The sensing unit 1020 can sense the state of the aerosol generating device 100 and the state around the aerosol generating device 100, and transmit the sensed information to the controller 1010. Based on the sensed information, the controller 1010 can control the aerosol generating device 100 to perform various functions, such as controlling the operation of the heater 1050, restricting smoking, determining whether an aerosol generating article (e.g., a cigarette, a cartridge, etc.) is inserted, displaying a notification, etc.
