When the cover 224 is covering the heating portion 222, the aerosol generating device 200 may remain deactivated. The cover 224 may slide up and down on the front surfaces 212c and 214c of the pad unit 210 of the aerosol generating device 200. When an aerosol generating article (e.g., an aerosol generating article 3 of FIG.
4) is inserted into an elongated cavity (e.g., an elongated cavity 240 of FIG. 3) of the aerosol generating device 200, the aerosol generating article 3 may push an end of the cover 224 such that the cover 224 covering the heating portion 222 slides down and uncover the heating portion 222. As a result, the aerosol generating device 200 is activated.

[93] The hinge unit 230 may allow the aerosol generating device 200 to smoothly transform between the spread mode MS and the rolling mode MR. The hinge unit may be a fixed hinge, a cylinder hinge, a table hinge, a piano hinge, or a combination thereof, but is not limited thereto.
[94] FIG. 3 is a diagram illustrating a rolling mode MR state of the aerosol generating device 200 according to an embodiment.
[95] In an embodiment, the aerosol generating device 200 may be transformed such that both edges of the edge pad unit 212 contact each other. The aerosol generating device 200 may be transformed into the rolling mode MR such that the front surfaces 212c and 214c of the pad units 212 and 214 face toward a central axis X-X. When the aerosol generating device 200 is transformed from the spread mode MS of FIG.

In this example, the edges of the edge pad units 212 may be coupled in a magnetic coupling manner, a snap-fit coupling manner, an interference fit manner, a snap and sliding manner, and the like. Desirably, the edges of the edge pad units 212 may be coupled in the magnetic coupling manner. However, the coupling of the ends of the edges of the edge pad units 212 is not limited to the above-mentioned coupling manners and may include other coupling manners.
14 [96] The pad units 212 and 214 may further include side surfaces 212e and 214e formed between the first end surfaces 212a and 214a and the second end surfaces 212b and 214b and between the front surfaces 212c and 214c and the rear surfaces 212d and 214d. The aerosol generating device 200 may be transformed to the rolling mode MR
(see Fig. 3) as the side surfaces 212e and 214e of the pad units 212 and 214 move away from each other, while the side surfaces 212e and 214e are disposed adjacent to each other between the respective pad units 212 and 214 in the spread mode MS
(see FIG. 2a).
[97] As the aerosol generating device 200 is transformed into the rolling mode MR, the elongated cavity 240 may be formed. The elongated cavity 240 may be a space in which an aerosol generating article is accommodated. The aerosol generating article may be accommodated in the elongated cavity 240 and heated by the heating unit of the aerosol generating device 200. The description related thereto is described in detail with reference to FIGS. 5a and 5b.
[98] FIG. 4 is a diagram illustrating an aerosol generating system S in which the aerosol generating article 3 is accommodated in a rolling mode MR state of the aerosol generating device 200 according to an embodiment.
[99] In the aerosol generating system S, the aerosol generating article 3 may be ac-commodated in the elongated cavity 240 of the aerosol generating device 200.
[100] When the aerosol generating article 3 is accommodated in the elongated cavity 240 of the aerosol generating device 200, the aerosol generating article 3 may open a cover (e.g., the cover 224 of FIG. 2b) of the heating unit 220 disposed on the front surfaces 212c and 214c of the respective pad units 212 and 214 of the aerosol generating device 200. While being inserted into the elongated cavity 240, the aerosol generating article 3 may push the cover 224 of the heating unit 220 downward and open the cover 224.
When the cover 224 of the heating unit 220 opens, the heating portion 222 covered by the cover 224 may be exposed to be disposed on a same plane as the front surfaces 212c and 214c of the pad units 212 and 214. The heating portion 222 may contact the aerosol generating article 3 and heat a medium and other aerosol generating articles disposed in the aerosol generating article 3 such that an aerosol is transmitted to a mouth of a user. Hereinafter, a structure for efficiently heating the aerosol generating article 3 is described in detail with reference to FIGS. 5a and 5b.
[101] FIGS. 5a and 5b are plan views of a state in which the aerosol generating article 3 is not inserted into the aerosol generating device 200 according to various embodiments.
[102] Referring to FIG. 5a, the aerosol generating device 200 may include the elongated cavity 240 having a triangular shape in a rolling mode MR (see FIG. 3). As described above, when the aerosol generating article 3 is inserted into the elongated cavity 240 of the aerosol generating device 200, and the aerosol generating article 3 may push the
(see Fig. 3) as the side surfaces 212e and 214e of the pad units 212 and 214 move away from each other, while the side surfaces 212e and 214e are disposed adjacent to each other between the respective pad units 212 and 214 in the spread mode MS
(see FIG. 2a).
[97] As the aerosol generating device 200 is transformed into the rolling mode MR, the elongated cavity 240 may be formed. The elongated cavity 240 may be a space in which an aerosol generating article is accommodated. The aerosol generating article may be accommodated in the elongated cavity 240 and heated by the heating unit of the aerosol generating device 200. The description related thereto is described in detail with reference to FIGS. 5a and 5b.
[98] FIG. 4 is a diagram illustrating an aerosol generating system S in which the aerosol generating article 3 is accommodated in a rolling mode MR state of the aerosol generating device 200 according to an embodiment.
[99] In the aerosol generating system S, the aerosol generating article 3 may be ac-commodated in the elongated cavity 240 of the aerosol generating device 200.
[100] When the aerosol generating article 3 is accommodated in the elongated cavity 240 of the aerosol generating device 200, the aerosol generating article 3 may open a cover (e.g., the cover 224 of FIG. 2b) of the heating unit 220 disposed on the front surfaces 212c and 214c of the respective pad units 212 and 214 of the aerosol generating device 200. While being inserted into the elongated cavity 240, the aerosol generating article 3 may push the cover 224 of the heating unit 220 downward and open the cover 224.
When the cover 224 of the heating unit 220 opens, the heating portion 222 covered by the cover 224 may be exposed to be disposed on a same plane as the front surfaces 212c and 214c of the pad units 212 and 214. The heating portion 222 may contact the aerosol generating article 3 and heat a medium and other aerosol generating articles disposed in the aerosol generating article 3 such that an aerosol is transmitted to a mouth of a user. Hereinafter, a structure for efficiently heating the aerosol generating article 3 is described in detail with reference to FIGS. 5a and 5b.
[101] FIGS. 5a and 5b are plan views of a state in which the aerosol generating article 3 is not inserted into the aerosol generating device 200 according to various embodiments.
[102] Referring to FIG. 5a, the aerosol generating device 200 may include the elongated cavity 240 having a triangular shape in a rolling mode MR (see FIG. 3). As described above, when the aerosol generating article 3 is inserted into the elongated cavity 240 of the aerosol generating device 200, and the aerosol generating article 3 may push the
15 cover 224 of the heating unit 220 downward and contact the heating portion 222. In this example, the aerosol generating article 3 having a circular cross-section may be heated by linearly contacting each surface of the elongated cavity 240 having a triangular cross-section.
[103] As the number of center pad units 214 of the pad units 210 included in the aerosol generating device 200 increases, the number of angles of the elongated cavity increases in the rolling mode MR. For example, an elongated cavity of an aerosol generating device with two center pad units 214 may have a quadrangular shape, and an elongated cavity of an aerosol generating device with four center pad units 214 may have a hexagonal shape. That is, as the number of center pad units 214 increases, the elongated cavity formed by the aerosol generating device in the rolling mode MR may become closer to a circle. As a result, a contact area of the heating portion 222 and the aerosol generating article 3 inserted into the elongated cavity may increase, and thus, efficient heating may be accomplished.
[104] Referring to FIG. 5b, the aerosol generating device 200 may include the elongated cavity 240 having a circular cross-section in the rolling mode MR (see FIG.
3).
According to another embodiment, the cover 224 and the heating portion 222 of a heating unit (e.g., the heating unit 220 of FIG. 2a and/or 2b) may have an arch structure. When the cover 224 and the heating portion 222 have an arch structure, the aerosol generating device 200 may form the elongated cavity 240 having the circular cross-section in the rolling mode MR, as illustrated in FIG. 5b. When the elongated cavity 240 is formed in a circular shape, the heating portion 222 and the aerosol generating article 3 inserted into the elongated cavity 240 may be in surface contact with each other, and thus, more efficient heating may be accomplished.
[105] As shown in FIGS. 5a and 5b, the side surface 212e of the edge pad unit 212 may include a first side surface 212e-1 and a second side surface 212e-2. In an embodiment, the first side surface 212e-1 may correspond to a side surface disposed adjacent to the center pad unit 214, and the second side surface 212e-2 may correspond to a side surface disposed to be spaced apart from the center pad unit 214.
[106] In an embodiment, an angle a between the second side surface 212e-2 and the front surface 212c of the edge pad unit 212 may correspond to an obtuse angle ranging from 90 degrees to 180 degrees. In this case, the second side surfaces 212e-2 may be in close contact with each other in the rolling mode MR, as illustrated in FIGS.
5a and/or 5b. Two angles a, each formed by the second side surface 212e-2 and the front surface 212c of the edge pad unit 212, may be different obtuse angles, but it is desirable that the two angles a are the same, as illustrated in FIGS. 5a and/or 5b. In an embodiment, the angle between the first side surface 212e-1 and the front surface 212c of the edge pad unit 212 and an angle between the side surface 214e and the front surface 214c of
[103] As the number of center pad units 214 of the pad units 210 included in the aerosol generating device 200 increases, the number of angles of the elongated cavity increases in the rolling mode MR. For example, an elongated cavity of an aerosol generating device with two center pad units 214 may have a quadrangular shape, and an elongated cavity of an aerosol generating device with four center pad units 214 may have a hexagonal shape. That is, as the number of center pad units 214 increases, the elongated cavity formed by the aerosol generating device in the rolling mode MR may become closer to a circle. As a result, a contact area of the heating portion 222 and the aerosol generating article 3 inserted into the elongated cavity may increase, and thus, efficient heating may be accomplished.
[104] Referring to FIG. 5b, the aerosol generating device 200 may include the elongated cavity 240 having a circular cross-section in the rolling mode MR (see FIG.
3).
According to another embodiment, the cover 224 and the heating portion 222 of a heating unit (e.g., the heating unit 220 of FIG. 2a and/or 2b) may have an arch structure. When the cover 224 and the heating portion 222 have an arch structure, the aerosol generating device 200 may form the elongated cavity 240 having the circular cross-section in the rolling mode MR, as illustrated in FIG. 5b. When the elongated cavity 240 is formed in a circular shape, the heating portion 222 and the aerosol generating article 3 inserted into the elongated cavity 240 may be in surface contact with each other, and thus, more efficient heating may be accomplished.
[105] As shown in FIGS. 5a and 5b, the side surface 212e of the edge pad unit 212 may include a first side surface 212e-1 and a second side surface 212e-2. In an embodiment, the first side surface 212e-1 may correspond to a side surface disposed adjacent to the center pad unit 214, and the second side surface 212e-2 may correspond to a side surface disposed to be spaced apart from the center pad unit 214.
[106] In an embodiment, an angle a between the second side surface 212e-2 and the front surface 212c of the edge pad unit 212 may correspond to an obtuse angle ranging from 90 degrees to 180 degrees. In this case, the second side surfaces 212e-2 may be in close contact with each other in the rolling mode MR, as illustrated in FIGS.
5a and/or 5b. Two angles a, each formed by the second side surface 212e-2 and the front surface 212c of the edge pad unit 212, may be different obtuse angles, but it is desirable that the two angles a are the same, as illustrated in FIGS. 5a and/or 5b. In an embodiment, the angle between the first side surface 212e-1 and the front surface 212c of the edge pad unit 212 and an angle between the side surface 214e and the front surface 214c of
16 the center pad unit 214 may each be 90 degrees, but the embodiments are not limited thereto.
[107] FIG. 6 is a diagram illustrating a state in which a pad cover 216 of the aerosol generating device 200 is taken off according to an embodiment.
[108] Referring to FIG. 6, various electronic/mechanical components may be included in each of the pad units 212 and 214. In an embodiment, magnetic bodies M1 and M2, a heat insulating member 250, a battery 260, and a controller 17 may be included in each of the pad units 212 and 214.
[109] The magnetic bodies M1 and M2 may be disposed on side surfaces of the edge pad unit 212. When the aerosol generating device 200 is in the rolling mode MR
(see FIG.
3), edges of the edge pad unit 212 may contact each other. In this example, the edges of the edge pad unit 212 may desirably be coupled in a magnetic coupling manner. The magnetic body M1 disposed on a side surface of the edge pad unit 212 disposed at an end of the aerosol generating device and the magnetic body M2 disposed on a side surface of the edge pad unit 212 disposed at another end of the aerosol generating device may generate an attractive force to be attached, and the aerosol generating device 200 may remain in a rolling mode MR state.
[110] The heat insulating member 250 may prevent heat generated by the heating portion 222 of the heating unit 220 from being transferred to rear surfaces (e.g., the rear surfaces 212d and 214d of FIG. 2b) of the pad units 212 and 214. The heat insulating member 250 may be disposed to enclose at least one surface of the heating portion 222, as illustrated in FIG. 6. Desirably, the heat insulating member 250 may be disposed to enclose at least three of surfaces except for surfaces facing front surfaces (e.g., the front surfaces 212c and 214c of FIG. 2a) of the pad units 212 and 214. More desirably, the heat insulating member 250 may be disposed to enclose all surfaces except for surfaces facing the front surfaces (e.g., the front surfaces 212c and 214c of FIG. 2a) of the pad units 212 and 214. The heat insulating member 250 may increase heating ef-ficiency of the aerosol generating article 3 of the aerosol generating device 200, and thus heat transferred to a gripping portion may decrease when a user uses the aerosol generating device 200.
[111] In an embodiment, the battery 260 may be disposed in at least one of the plurality of pad units 210. When the battery 260 is disposed in only one pad unit of the plurality of pad units 210, a weight of the aerosol generating device 200 may decrease, thereby in-creasing its portability. When the battery 260 is disposed in two or more pad units of the plurality of pad units 210, a total battery capacity of the aerosol generating device 200 may increase, thereby increasing power efficiency and hours of use.
[112] In an embodiment, the controller 270 may control the overall operation of the aerosol generating device 200. In an embodiment, the controller 270 may include at least one

[109] The magnetic bodies M1 and M2 may be disposed on side surfaces of the edge pad unit 212. When the aerosol generating device 200 is in the rolling mode MR
(see FIG.
3), edges of the edge pad unit 212 may contact each other. In this example, the edges of the edge pad unit 212 may desirably be coupled in a magnetic coupling manner. The magnetic body M1 disposed on a side surface of the edge pad unit 212 disposed at an end of the aerosol generating device and the magnetic body M2 disposed on a side surface of the edge pad unit 212 disposed at another end of the aerosol generating device may generate an attractive force to be attached, and the aerosol generating device 200 may remain in a rolling mode MR state.
[110] The heat insulating member 250 may prevent heat generated by the heating portion 222 of the heating unit 220 from being transferred to rear surfaces (e.g., the rear surfaces 212d and 214d of FIG. 2b) of the pad units 212 and 214. The heat insulating member 250 may be disposed to enclose at least one surface of the heating portion 222, as illustrated in FIG. 6. Desirably, the heat insulating member 250 may be disposed to enclose at least three of surfaces except for surfaces facing front surfaces (e.g., the front surfaces 212c and 214c of FIG. 2a) of the pad units 212 and 214. More desirably, the heat insulating member 250 may be disposed to enclose all surfaces except for surfaces facing the front surfaces (e.g., the front surfaces 212c and 214c of FIG. 2a) of the pad units 212 and 214. The heat insulating member 250 may increase heating ef-ficiency of the aerosol generating article 3 of the aerosol generating device 200, and thus heat transferred to a gripping portion may decrease when a user uses the aerosol generating device 200.
[111] In an embodiment, the battery 260 may be disposed in at least one of the plurality of pad units 210. When the battery 260 is disposed in only one pad unit of the plurality of pad units 210, a weight of the aerosol generating device 200 may decrease, thereby in-creasing its portability. When the battery 260 is disposed in two or more pad units of the plurality of pad units 210, a total battery capacity of the aerosol generating device 200 may increase, thereby increasing power efficiency and hours of use.
[112] In an embodiment, the controller 270 may control the overall operation of the aerosol generating device 200. In an embodiment, the controller 270 may include at least one
17 processor. The processor may be implemented as an array of a plurality of logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory in which a program executable by the microprocessor is stored. In addition, it is to be understood by one of ordinary skill in the art to which the disclosure pertains that the processor may be implemented in other types of hardware. In an embodiment, the controller 270 may be disposed across two or more pad units 210, in which case, the controller 270 may include a flexible printed circuit board (FPCB) to operate smoothly in the spread mode MS and the rolling mode MR of the aerosol generating device 200. In an embodiment, the controller 270 may control the aerosol generating device 200 such that the aerosol generating device 200 remains deactivated in the spread mode MS (see FIG. 2a) and is activated to operate in the rolling mode MR (see FIG. 3).
