[0069] The second blade 330 may include a second blade body 331 and a second blade chamfer 332. The second blade body 331 may have a circular cross section. The second blade chamfer 332 may define an inclined surface at the lower end of the second blade body 331. The second blade chamfer 332 may be formed by obliquely cutting the lower surface of the second blade body 331. The second blade chamfer 332 may be provided in pairs.

[0070] The second blade 330 may include a second blade edge 333. The second blade edge 333 may define an edge at an end of the second blade 333. A pair of second blade chamfered surfaces 332 may intersect each other at the second blade edge 333. A pair of second blade chamfered surfaces 332 may extend obliquely upward to opposite sides from the second blade edge 333. The second blade edge 333 may extend in a horizontal direction. The second blade 330 may be made of a metal material.

[0071] The center of the second blade 330 may be opened to define a second blade hole 334. The second blade hole 334 may be formed in a cylindrical shape and may be elongated upward. The second blade 330 may be inserted into the first insertion space 14, and the heater rod 31 may be inserted into the second blade hole 334 (see Figure 35 to Figure 3 7).

[0072] The diameter D1 or width D1 of the first blade 310 may be different from the diameter D2 or width D2 of the second blade 330. The diameter D2 of the second blade 330 may be greater than the diameter D1 of the first blade 310. The diameter of the first insertion space 14 may be greater than the diameter of the second insertion space 24. The first blade 310 may be inserted into the second insertion space 24 (see Figure 1 ) to clean the inside of the second insertion space 24. The diameter D1 of the first blade 310 may be substantially similar to the diameter of the second insertion space 24. The second blade 330 may be inserted into the first insertion space 14 (see Figure 1 ) to clean the inside of the first insertion space 14. The diameter D2 of the second blade 330 may be substantially similar to the diameter of the first insertion space 14.

[0073] Each of the pair of first rods 210 may be configured to be bent toward the second rod 220. Therefore, the first rod 210 and the second rod 220 may be closer to each other. This may narrow the width of the slit 204 between the first rod 210 and the second rod 220. Here, the first stopper 211, the wing 212, and the second stopper 213 fixed to the first rod 210 may move toward the second rod 220 together with the first rod 210. The rod 200 may be made of a material having excellent rigidity and elasticity. For example, the rod 200 may be made of plastic.

[0074] Reference Fig. 9 , the first blade 310 may include a first blade fixing member 315. The first blade fixing member 315 may be formed at the lower end of the first blade 310. The first blade fixing member 315 may protrude downward from the first blade body 311. The first blade fixing member 315 may include a cross section having a non-circular shape. For example, the outer peripheral surface of the first blade fixing member 315 may have a sawtooth shape or a concave-convex shape that causes friction in the circumferential direction. Alternatively, the first blade fixing member 315 may include a horizontal cross section having a triangular shape, a square shape, etc.

[0075] The first rod head 232 may have a first blade coupling groove 234 opened at the top. The first blade fixing member 315 may be inserted into the first blade coupling groove 234 and fixed to the first blade coupling groove 234. The inner circumferential surface 235 of the first rod head 232 may have a shape corresponding to the outer circumferential surface of the first blade fixing member 315. For example, the outer circumferential surface of the first blade fixing member 315 and the inner circumferential surface 235 of the first rod head 232 may have a sawtooth shape corresponding to each other so as to be engaged with each other in the circumferential direction. The outer circumferential surface of the first blade fixing member 315 and the outer circumferential surface 235 of the first blade coupling groove 234 (i.e., the inner circumferential surface 235 of the first rod head 232) may be engaged with each other, thereby preventing the first blade 310 from circumferentially moving relative to the rod 200.

[0076] The pin 320 may include a pin body 323. The pin body 323 may be vertically elongated. The pin body 323 may extend downward from the pin blade 321. The pin 320 may include a pin fixing member 325. The pin fixing member 325 may be formed below the pin body 323. The pin fixing member 323 may include a cross section having a non-circular shape. For example, the outer peripheral surface of the pin fixing member 323 may have a sawtooth shape or a concave-convex shape that causes friction in the circumferential direction. Alternatively, the pin fixing member 323 may include a cross section having a triangular shape, a square shape, etc.

[0077] The first blade 310 may have a first blade hole 314 opened at the top. The outer peripheral surface of the first blade hole 314 may have a shape corresponding to the outer peripheral surface of the pin fixing member 323. For example, the outer peripheral surface of the pin fixing member 323 and the outer peripheral surface of the blade hole 314 may have a sawtooth shape corresponding to each other so as to be engaged with each other in the circumferential direction. When the outer peripheral surface of the pin fixing member 325 and the outer peripheral surface of the first blade hole 314 are engaged with each other, the pin 320 can be prevented from circumferentially moving relative to the rod 200.

[0078] Therefore, when the cleaning kit is rotated in the circumferential direction (see Fig.26 ), which can prevent the first blade 310 and / or the pin 320 from rotating relative to the rod 200 along the circumferential direction, thereby fixing the first blade 310 and / or the pin 320.

[0079] Reference Fig.10 , the second blade 330 may include a second blade fixing member 335. The second blade fixing member 335 may be formed at the upper end of the second blade 330. The second blade fixing member 335 may protrude upward from the second blade body 331. The second blade fixing member 335 may include a cross section having a non-circular shape. For example, the outer peripheral surface of the second blade fixing member 335 may have a sawtooth shape or a concave-convex shape that causes friction in the circumferential direction. Alternatively, the second blade fixing member 335 may include a cross section having a triangular shape, a square shape, etc.

[0080] The second rod head 242 may have a second blade coupling groove 244 opened at the bottom. The second blade fixing member 335 may be inserted into the second blade coupling groove 244 and fixed to the second blade coupling groove 244. The inner circumferential surface 245 of the second rod head 242 may have a shape corresponding to the outer circumferential surface of the second blade fixing member 335. For example, the outer circumferential surface of the second blade fixing member 335 and the inner circumferential surface 245 of the second rod head 242 may have a sawtooth shape corresponding to each other so as to engage with each other in the circumferential direction. The outer circumferential surface of the second blade fixing member 335 and the outer circumferential surface 245 of the second blade coupling groove 244 (i.e., the inner circumferential surface 245 of the second rod head 242) may engage with each other, thereby preventing the second blade 330 from moving in the circumferential direction relative to the rod 200.

[0081] Therefore, when the cleaning kit is rotated in the circumferential direction (see Fig.34 ), which can prevent the second blade 330 from rotating relative to the rod 200 along the circumferential direction, thereby fixing the second blade 330.

[0083] The inner wall 120 of the frame 120 may include a first inner wall 120a and a second inner wall 120b. A pair of the first inner walls 120a and a pair of the second inner walls 120b may define the rod hole 104. The pair of first inner walls 120a may be disposed at opposite sides relative to the rod hole 104 to face each other. A pair of second inner walls 120b may be disposed at opposite sides relative to the rod hole 104 to face each other. The opposite ends of the first inner wall 120a may be connected to the corresponding ends of the pair of second inner walls 120b. The opposite ends of the second inner wall 120b may be connected to the corresponding ends of the pair of first inner walls 120a. The first inner wall 120a and the second inner wall 120b may be arranged alternately along the circumferential direction.

[0084] The frame 100 may include a first engagement portion 121. The first engagement portion 121 may be formed on the first inner wall 120a of the frame 100. The upper end of the first inner wall 120a of the frame 100 may be recessed downward to define the first engagement portion 121. A pair of first engagement portions 121 may be disposed opposite to each other with respect to the rod hole 104.

[0085] The frame 100 may include a second engaging portion 123. The second engaging portion 123 may be formed on the first inner wall 120a of the frame 100. The lower end of the first inner wall 120a of the frame 100 may be recessed upward to define the second engaging portion 123. A pair of second engaging portions 123 may be arranged opposite to each other relative to the rod hole 104. The second engaging portion 123 may be formed at a position corresponding to the first engaging portion 121 in the vertical direction. The second engaging portion 123 may be positioned below the first engaging portion 121. The first engaging portion 121 and the second engaging portion 123 may be vertically spaced apart from each other by a predetermined distance. The spacing distance between the first stopper 121 and the second stopper 123 may be equal to or approximate to the spacing distance between the first stopper 211 and the second stopper 213.

[0086] The frame 100 may include a slide groove 124. The second inner wall 120b of the frame 100 may be recessed outward from the rod hole 104 to define the slide groove 124. The slide groove 124 may be vertically elongated. The slide groove 124 may be in communication with the rod hole 104. A pair of slide grooves 124 may be disposed opposite to each other with respect to the rod hole 104.

[0087] The frame 100 may include a third engaging portion 125. The third engaging portion 125 may be formed adjacent to the upper side of the sliding groove 124. The third engaging portion 125 may be bent from the upper end of the second inner wall 120b toward the rod hole 104. The third engaging portion 125 may protrude toward the rod hole 104. A pair of third engaging portions 125 may be disposed on opposite sides with the sliding groove 124 interposed therebetween. The pair of third engaging portions 125 may be positioned opposite to each other relative to the rod hole 104 so as to face each other.

[0088] Reference Figures 13 to 15 , the rod 200 may be coupled to the frame 100 or supported by the frame 100. The rod 200 may pass through the rod hole 104 of the frame 100 so as to protrude upward and downward from the frame 100. A portion of the circumference of the rod 200 may be surrounded by the inner wall 120 of the frame 100. The rod 200 may be supported by the inner wall 120 of the frame 100. The first cap 410 and / or the second cap 430 may be coupled to the frame 100. The upper end of the rod 200 may be disposed inside the first cap 410. The lower end of the rod 200 may be disposed inside the second cap 430.

[0089] The edge of the second rod 220 may be inserted into the slide groove 124. The edge of the second rod 220 may be supported by the second inner wall 120b of the frame 100 in the slide groove 124. The slide groove 124 and the second rod 220 may be elongated in a vertical or longitudinal direction.

[0090] The rod 200 may be located at a first position relative to the frame 100. The first position may be a state before the rod 200 is moved from the frame 100.

[0091] Reference Fig.13, the outer surface of the first rod 210 may be supported by the inner surface of the first inner wall 120a of the frame 100. The first stopper 211 may be supported by the second engaging portion 123. The first stopper 211 may be disposed below the second engaging portion 123. The wing 212 (see Figure 7 ) can be supported by the inner surface of the first inner wall 120a.

[0092] Reference Fig.14 and Fig.15 , the opposite ends of the third stopper 221 may be supported by the third engaging portion 125 at the opposite side. The third stopper 221 may be disposed on the third engaging portion 125. The third engaging portion 125 may support the opposite surface of the rod 200. The opposite ends of the fourth stopper 223 may be supported by the inner surface of the second inner wall 120b of the frame 100.

[0093] Therefore, the frame 100 can support the bottom of the third stopper 221 and the top of the first stopper 211, thereby fixing the rod 200 in the longitudinal direction relative to the frame 100. In addition, the frame 100 can surround and support the rod 200, thereby fixing the rod 200 in the transverse direction relative to the frame 100.

[0094] Reference Fig.16 and Fig.17 , the first cap portion 410 may include a side wall 411 and an upper wall 412. The periphery of the first chamber 414 may be surrounded by the side wall 411 of the first cap portion 410. The upper portion of the first chamber 414 may be covered by the upper wall 412 of the first cap portion 410. The lower portion of the first chamber 414 may be open.

[0095] The side wall 411 of the first cap portion 410 may be opened to define a pusher hole 4114. The pusher hole 4114 may be communicated with the first chamber 414. A pair of pusher holes 4114 may be disposed opposite to each other with respect to the first chamber 414 so as to face each other.

[0096] The positioning portion 413 may protrude downward from the inner surface of the upper wall 412 of the first cap portion 410 toward the first chamber 414. The positioning portion 413 may be disposed near the center of the upper wall 412. A pair of positioning portions 413 may be disposed opposite to each other relative to the center. A pair of positioning portions 413 may be vertically aligned with the position of the first blade 310. The lower surface of the positioning portion 413 may be recessed upward. The lower surface of the positioning portion 413 may have a shape corresponding to the upper surface of the first blade 310. The lower surface of the positioning portion 413 may be inclined to correspond to the upper end of the first blade 310.

[0097] The pusher assembly 420 may include a first pusher 421 and a second pusher 422. The pusher assembly 420 may include a first pusher bar 425. The pusher assembly 420 may include a second pusher bar 426.

[0098] The pair of first pusher bars 425 may be elongated vertically. The pair of first pusher bars 425 may be spaced apart from each other by a predetermined distance so as to be arranged parallel to each other. The second pusher bar 426 may be disposed between the pair of first pusher bars 425. The second pusher bar 426 may connect the upper ends of the pair of first pusher bars 425. The second pusher bar 426 may be elongated in the horizontal direction. The first pusher bar 425 may extend downward from the end of the second pusher bar 426.

[0099] The first pusher 421 may be adjacent to a lower end of the first pusher bar 425. The first pusher 421 may protrude from an outer surface of the first pusher bar 425 toward the outside of the pusher assembly 420.

[0100] The second pusher 422 may be disposed at a position corresponding to the first pusher 421. The first pusher 422 may be adjacent to the lower end of the first pusher strip 425. The first pusher strip 425 may be disposed between the first pusher 421 and the second pusher 422. The second pusher 422 may be disposed opposite to the first pusher strip 425. The second pusher 422 may be adjacent to the end of the first pusher strip 425. The second pusher 422 may protrude from the inner surface of the first pusher strip 425 toward the inside of the pusher assembly 420. The inner surface of the second pusher 422 may be curved. The inner surface of the second pusher 422 may be concave inwardly. The inner surface of the second pusher 422 may correspond to the curved outer peripheral surface of the first rod 210. The inner surface of the second pusher 422 may be in close contact with one side of the outer peripheral surface of the first rod 210 in a covering manner.

[0101] The rib 423 may protrude inward from the inner surface of the first pusher bar 425. The rib 423 may be disposed at a position corresponding to the first pusher 421. The rib 423 may extend from the inner surface of the first pusher bar 425 toward the second pusher 422. The rib 423 may support the second pusher 422. The rib 423 may enhance the rigidity of the second pusher 422. The rib 423 may be inclined so that its width gradually decreases upward.

[0102] The second pusher bar 426 may be opened to define a slit 424. The slit 424 may be elongated in a longitudinal direction of the second pusher bar 426. The slit 424 may be formed at a position corresponding to the positioning portion 413.

[0103] The pusher assembly 420 may be inserted into the first chamber 414 defining the interior of the first cap portion 410. The first pusher 421 may pass through the pusher hole 4114 to protrude out of the first cap portion 410. The second pusher 422 may protrude toward the first chamber 414. The positioning portion 413 may pass through the slot 424 to protrude below the slot 424.

[0104] The pusher assembly 420 may be supported by the first cap portion 410. The outer surface of the first pusher bar 425 may be supported by the inner surface of the side wall 411 of the first cap portion 410. The first pusher bar 425 may extend longer along the side wall 411 of the first cap portion 410 to the upper wall 412 of the first cap portion 410. The upper surface of the second pusher bar 426 may be supported by the lower surface of the upper wall 412 of the first cap portion 410. The second pusher bar 426 may be fixed to the first cap portion 410.

[0105] The pusher assembly 420 can be made of a material having excellent elasticity and rigidity. For example, the pusher assembly 420 can be made of plastic. The pusher assembly 420 can have a restoring force. The first pusher 421 can move horizontally in the pusher hole 4114. When the first pusher 421 is pressed toward the inside of the first cap 410, the first pusher strip 425 can be tilted toward the inside of the first cap 410 relative to the second pusher strip 426. The first pusher 421 and the second pusher 422 can move toward the inside of the first cap 410 together with the first pusher strip 425. The gap between a pair of second pushers 422 can be narrowed. When the first pusher 421 is not pressed, the first pusher strip 425 can be tilted toward the outside of the first cap 410 relative to the second pusher strip 426, so that the first pusher 421 and the second pusher 422 return to their initial positions.

[0106] Reference Figures 18 to 22 , the rod 200 may be movably coupled to the frame 100. The rod 200 may be movable in its longitudinal direction relative to the frame 100. The rod 200 may be elongated in the vertical direction, and the rod 200 may be movable up and down relative to the frame 100. The rod 200 may be moved relative to the frame 100 from a first position (see Fig.18 ) moves up to the second position (see Fig.21 and Fig. 22 ). A method in which the rod 200 is movably coupled to the frame 100 in a longitudinal direction of the rod 200 relative to the frame 100 may vary. The following description is merely an example, and the moving method of the rod 200 is not limited thereto.

[0107] In the first position, the first stopper 211 may be supported by the second engagement portion 123, thereby fixing the rod 200. In the second position, the first stopper 211 may be supported by the first engagement portion 121, and the second stopper 213 may be supported by the second engagement portion 123, thereby fixing the rod 200. This may put the first blade 310 and the pin 320 in a usable state.

[0108] The height H2 from the bottom of the second insertion space 24 to the insertion hole 44 may be greater than the height H1 of the first insertion space 14 (see Figure 2). Thus, by moving the rod 200 to the second position, the upper portion of the rod 200 may further protrude upward from the frame 100, so that the cleaning kit is changed into a shape suitable for cleaning the second insertion space 24. In addition, the cleaning kit may be manufactured in a compact size.

[0109] Reference Fig.18 and Fig.19 When the first pusher 421 is pressed, the first pusher bar 425 may be tilted toward the inside of the first cap portion 410 relative to the second pusher bar 426 , thereby allowing the first pusher 421 and the second pusher 422 to move toward the inside of the first cap portion 410 .

[0110] Therefore, the pair of second pushers 422 may respectively press the pair of first rods 210 toward the second rod 220. With respect to the first connection portion 231 and the second connection portion 241, the pair of first rods 210 may be configured to bend toward the second rod 220 along the thickness direction of the first rod 210. The first rod 210 may be bent inward. This may narrow the width of the slit 204.

[0111] The first stopper 211 may be moved toward the second rod 220 together with the first rod 210. The width between the pair of first rods 210 may be narrowed. The width between the pair of first stoppers 211 may be narrowed.

[0112] The first stopper 211 may be further moved inwardly relative to the second engagement portion 123 and the first inner wall 120a of the frame 100. The first stopper 211 may be in a state of being released from the second engagement portion 123.

[0113] Therefore, the first cap portion 410 may be removed upward from the frame 100, and at the same time, the rod 200 in the first position may be moved upward by picking up or holding the rod 200 using the pusher assembly 420. The first coupling protrusion 115a may be separated from the first coupling groove 415. The first stopper 211 may be supported on the inner side of the first inner wall 120a and may slide upward.

[0114] Reference Fig.19 and Fig. 20 , when the first cap 410 moves upward while reducing the force pressing the first pusher 421, the first cap 410 may move upward relative to the rod 200. Here, the second pusher 422 may support the first rod 210 and slide upward along the first rod 210, so that the first cap 410 moves while being aligned relative to the rod 200. When the first cap 410 moves upward while reducing the force pressing the first pusher 421, the second pusher 422 may be inserted into the recessed portion 233 and engaged with the recessed portion 233 while moving.

[0115] Reference Fig. 20 and Fig.21, when the second pusher 422 is inserted into and engaged with the recessed portion 233, the pusher assembly 420 may not receive resistance from the restoring force of the first rod 210. Therefore, the rod 200 may move upward relative to the frame 100 with a relatively reduced force pressing the first pusher 421. Alternatively, by pressing the first pusher 421 with the same force, the rod 200 may move upward without the second pusher 422 being inserted into the recessed portion 233.

[0116] When the rod 200 moves a predetermined distance to reach the second position, the bent first rod 210 may be restored to a state parallel to the second rod 220. The first stopper 211 may be engaged with the first engagement portion 121. The second stopper 213 may be engaged with the second engagement portion 123. An outer peripheral surface of the first rod 210 between the first stopper 211 and the second stopper 213 may be supported by the first inner surface 120a of the frame 100.

[0117] Thus, in the second position, the rod 200 may be fixed in position relative to the frame 100 .

[0118] Reference Fig.21 and Fig. 22 When the first pusher 421 is not pressed, the second pusher 422 inserted into the recess 233 may be separated from the recess 233. Therefore, when the lever 200 is located at the second position, the first cap 410 may be removed from the lever 200, and the first blade 310 and the pin 320 may be exposed to the outside.

[0119] Reference Fig.14 and Fig.23 , when the rod 200 moves from the first position to the second position, the second rod 220 may slide upward on the sliding groove 124. The third stopper 221 may be separated upward from the third engaging portion 125. When the rod 200 moves, the second rod 220 may be supported by the second inner wall 120b of the frame 100 and the third engaging portion 125. Therefore, the rod 200 may move in a stable manner. In the second position, the disk 243 may be engaged with and supported by the lower end of the inner wall 120 of the frame 100. Therefore, the upward movement of the rod 200 may be limited or suppressed.

[0120] Reference Fig.15 and Fig.24 , the fourth stopper 223 may be supported by the second inner wall 120b of the frame 100. When the rod 200 moves from the first position to the second position, the fourth stopper 223 may be supported by the second inner wall 120b of the frame 100 and may slide upward. Therefore, the rod 200 may move in a stable manner.

[0121] In the first position, the third stopper 221 may be supported by the upper portion of the third engaging portion 125. In the second position, the third stopper 221 may be separated from the third engaging portion 125, and the fourth stopper 223 may be engaged with and supported by the lower portion of the third engaging portion 125. Thus, the upward movement of the rod 200 may be limited or suppressed.

[0122] Reference Fig.25 In a state where the first cap 410 is removed from the frame 100 , the rod 200 , the first blade 310 , and the pin 320 located at the second position may be inserted in the second insertion space 24 of the extractor 20 .

[0123] The length from the upper end of the frame 100 to the end of the first blade 310 may be equal to or greater than the height H2 from the bottom of the second insertion space 24 to the insertion hole 44 (see Figure 2 ). When the first blade 310 and the upper portion of the rod 200 are inserted into the second insertion space 24, the upper end of the frame 100 may be spaced apart from the upper housing 40. The end of the first blade 310 may contact the second flange 22 of the extractor 20. The pin 320 may be inserted into the through hole 23. The outer circumferential surface of the rod 200 and the second insertion space 24 may have a cylindrical shape corresponding to each other. The through hole 23 may have a circular cross-section.

[0124] Therefore, the user may rotate the cleaning kit in the circumferential direction while holding the frame 100 and / or the second cap 430 to rotate the first blade 310 and the pin 320 in the second insertion space 24 , thereby allowing cleaning of the extractor 20 .

[0125] Reference Figure 26 to Figure 28 , when the cartridge S is removed from the second insertion space 24 of the extractor 20 after using the aerosol generating device (see Figure 2 ), residues a1, a2, and a3 as aerosol residues or residues leaked from the cartridge S may accumulate in the extractor 20. These residues a1, a2, and a3 adhered to the extractor 20 at high temperatures may cool and harden into a solid, making them difficult to remove from the extractor 20.

[0126] The first blade 310 may be inserted into the second insertion space 24 so as to move toward the second flange 22. The first blade edge 313 may contact the second flange 22. The pin 320 may pass through the through hole 23. The first blade 310 and the pin 320 may remove the residues a1, a2, and a3 adhered to the extractor 20. The first blade 310 and the pin 320 may be made of a metal having higher rigidity than the residues a1, a2, and a3 in a solid state.

[0127] When the pin 320 passes through the through hole 23, the first residue a1 adhered around the through hole 23 may be removed. Here, the remaining first residue a1 may be scraped off as the pin blade 321 rotates in the circumferential direction in the through hole 23, thereby removing the remaining first residue a1. The maximum diameter D3 of the pin blade 321 may be equal to or similar to the diameter D4 of the through hole 23. Since the pin tip 322 is obliquely formed, that is, formed in a chamfered shape, although the diameter D4 of the through hole 23 is narrowed due to the first residue a1, the pin tip 322 may easily pass through the through hole 23, thereby removing the first residue a1.

[0128] The first blade 310 can move toward the second flange 22, and then can collide with the second residue a2 and the third residue a3 adhered to the upper surface of the second flange 22. The first blade edge 313 can collide with the second residue a2 and the third residue a3, thereby decomposing the second residue a2 and the third residue a3. The second residue a2 and the third residue a3 can be decomposed into smaller pieces by repeating the above process. The first blade 310 positioned in the second insertion space 24 can rotate along the circumferential direction when adjacent to or in contact with the second flange 22, so as to scrape off the undecomposed second residue a2 and the third residue a3. Therefore, the second residue a2 and the third residue a3 can be easily removed.

[0129] Reference Figure 29 to Figure 32 , the first cap portion 410 may push the rod 200 to the first position when it is again coupled to the frame 100, so that the second cap portion 430 may be removed from the frame 100. This may place the second blade 330 in a usable state.

[0130] Reference Fig.29 and Fig.30 When the lever 200 is located at the second position, the first blade 310 and the pin 320 may be inserted into the first chamber 414 inside the first cap 410. Here, the lower surface of the positioning portion 413 may contact the first blade chamfered surface 312 (see Fig.23 ). The lower surface of the positioning portion 413 may have a slope substantially corresponding to the slope of the pair of first blade chamfered surfaces 312. The lower surface of the positioning portion 413 may contact the first blade chamfered surfaces 312 so as to guide the positioning portion 413 to align with the first blade chamfered surfaces 312.

[0131] Therefore, the first cap portion 410 can be aligned in place relative to the frame 100. Here, the pair of second pushers 422 can respectively contact the outer peripheral surfaces of the pair of first rods 210. In addition, the position of the first coupling protrusion 115a and the position of the first coupling groove 415 can be vertically aligned with each other. In addition, the position of the first cap portion guide 117a and the position of the first guide groove 417 can be vertically aligned with each other.

[0132] Reference Fig.30 and Fig.31 , in a state where the first cap portion 410 is properly aligned with respect to the frame 100, the first pusher 421 may be pressed toward the inside of the first cap portion 410. When the first pusher 421 is pressed, the first pusher bar 425 may be tilted toward the inside of the first cap portion 410 relative to the second pusher bar 426, and the first pusher 421 and the second pusher 422 may move toward the inside of the first cap portion 410.

[0133] Therefore, the pair of second pushers 422 may respectively press the pair of first rods 210 toward the second rod 220. With respect to the first connection portion 231 and the second connection portion 241, the pair of first rods 210 may be configured to bend toward the second rod 220 along the thickness direction of the first rod 210. The first rod 210 may be bent inward. This may narrow the width of the slit 204.

[0134] The first stopper 211 may be moved toward the second rod 220 together with the first rod 210. The width between the pair of first rods 210 may be narrowed. The width between the pair of first stoppers 211 may be narrowed.

[0135] The first stopper 211 may be further moved inwardly relative to the first engagement portion 121 and the first inner wall 120a of the frame 100. The first stopper 211 may be in a state of being released from the first engagement portion 121.

[0136] Therefore, the rod 200 in the second position may be moved downward by pushing downward the first cap portion 410. The first stopper 211 may be supported on the inner side of the first inner wall 120a and may slide downward.

[0137] Reference Fig.31 and Fig.32 , the rod 200 can be moved to the first position by pushing the first cap portion 410 downward, and the first cap portion 410 can be coupled to the frame 100. When the first pusher 421 is not pressed, the first stopper 211 can be engaged with and supported by the second engagement portion 123. The first stopper 211 can be supported by the second engagement portion 123, thereby limiting the upward movement of the rod 200. The third stopper 221 (see Fig.14 ) may be engaged with and supported by the third engaging portion 125. The third stopper 221 may be supported by the third engaging portion 125, thereby limiting or inhibiting downward movement of the rod 200. The first stopper 211 and the third stopper 221 may be supported by the frame 200, thereby fixing the rod 200 to the frame 100.

[0138] When the second cap 430 is removed from the frame 100 in a state where the lever 200 is located at the first position, the second blade 330 may be exposed to the outside. A lower end of the lever 200 and the second blade 330 may protrude downwardly from the frame 100.

[0139] Reference Fig.33 In a state where the second cap 430 is removed from the frame 100 , the rod 200 and the second blade 330 located at the first position may be inserted into the first insertion space 14 .

[0140] The length from the lower end of the frame 100 to the end of the second blade 330 may be equal to or greater than the height H1 of the first insertion space 14 (see Figure 2 In a state where the lower portion of the second blade 330 and the lower portion of the rod 200 are inserted into the first insertion space 14 , the lower end of the frame 100 may be spaced apart from the body 100 .

[0141] Therefore, the user may rotate the cleaning kit in the peripheral direction 14 while holding the frame 100 and / or the first cap 410 to rotate the second blade 330 in the first insertion space 14 , thereby allowing the inside of the first insertion space 14 to be cleaned.

[0142] Reference Figure 34 to Figure 36 , when the cigarette cartridge S is removed from the second insertion space 24 after using the aerosol generating device (see Figure 2 ), residues a4, a5, and a6 that are aerosol residues or residues leaked from the cigarette cartridge S may accumulate in the first insertion space 14. These residues a4, a5, and a6 that adhere to the outer peripheral surfaces of the pipes (11, 12) and the heater assembly 30 at high temperatures may cool and harden into a solid, making them difficult to remove from the pipes (11, 12) or the heater assembly 30.

[0143] The second blade 330 may be inserted into the first insertion space 14 to move toward the first flange 12. The second blade edge 333 may contact the first flange 12. The heater assembly 30 may be inserted into the second blade hole 334. The outer peripheral surface of the heater assembly 30 and the outer peripheral surface of the second blade hole 334 (i.e., the inner peripheral surface of the second blade 330) may have shapes corresponding to each other. The second blade 330 may remove the residues a4, a5, and a6 adhered to the pipe (11, 12) and the heater assembly 30. The second blade 330 may be made of a metal having a higher rigidity than the residues a4, a5, and a6 in a solid state.

[0144] When the heater assembly 30 is inserted into the second blade hole 334, the fourth residue a4 adhered to the outer peripheral surface of the heater assembly 30 can be scraped off by the inner peripheral surface of the second blade 330, thereby removing the fourth residue a4. The diameter D5 of the second blade hole 334 may be equal to or similar to the diameter D6 of the heater assembly 30. Here, in order to remove the remaining fourth residue a4 by rotating the cleaning kit, the inner peripheral surface of the second blade 330 may have a concave-convex shape such as a sawtooth shape.

[0145] The second blade 330 can move toward the first flange 12, and then can collide with the fifth residue a5 and the sixth residue a6 adhered to the upper surface of the first flange 12. The second blade edge 333 can collide with the fifth residue a5 and the sixth residue a6, thereby decomposing the fifth residue a5 and the sixth residue a6. The fifth residue a5 and the sixth residue a6 can be decomposed into smaller pieces by repeating the above process. The second blade 330 positioned in the first insertion space 14 can rotate along the circumferential direction when adjacent to or in contact with the first flange 12, so as to scrape off the undecomposed fifth residue a5 and the sixth residue a6. Therefore, the fifth residue a5 and the sixth residue a6 can be easily removed.

[0146] The outer circumferential surface of the disk 243 may be in contact with the inner circumferential surface of the first sidewall 11 of the duct (11, 12). The outer circumferential surface of the second blade 330 may be spaced inwardly from the inner circumferential surface of the first sidewall 11.

[0147] Therefore, the contact resistance with the second blade 330 can be reduced, so that the second blade 330 can be easily rotated. In addition, damage to the pipe (11, 12) or the second blade 330 can be reduced.
