[0067] The second blade 330 can be fixed to the lower end of the rod 200. The second blade 330 can be coupled to the second rod head 242. The second blade 330 may have a tip shape that gradually becomes thinner towards the lower side.

[0068] The second blade 330 can include a second blade body 331 and a second blade chamfer 332. The second blade body 331 can have a circular cross-section. The second blade chamfer 332 can form an inclined surface at the lower end of the second blade body 331. The second blade chamfer 332 can be formed by obliquely cutting the lower surface of the second blade body 331. The second blade chamfers 332 can be formed in a pair.

[0069] The second blade 330 can include a second blade edge 333. The second blade edge 333 can form a corner at the end of the second blade 331. The second blade chamfers 332 can be in contact with each other at the second blade edge 333. The pair of second blade chamfers 332 can be formed to incline upward from the second blade edge 333 to both sides. The second blade edge 333 can extend in the lateral direction. The second blade 330 can be formed of a metal material.

[0070] The center of the second blade 330 can be open to form a second blade hole 334. The second blade hole 334 is formed in a cylindrical shape and can extend long upward. The second blade 330 can be inserted into the first insertion space 14, and the heater rod 31 can be inserted into the second blade hole 334 (see FIGS. 35 to 37).

[0071] 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 larger than the diameter D1 of the first blade 310. The diameter of the first insertion space 14 may be larger than the diameter of the second insertion space 24. The first blade 310 can be inserted into the second insertion space 24 (see FIG. 1) and can clean the inside of the second insertion space 24. The diameter D1 of the first blade 310 may be substantially the same as the diameter of the second insertion space 24. The second blade 330 can be inserted into the first insertion space 14 (see FIG. 1) and can clean the inside of the first insertion space 14. The diameter D2 of the second blade 330 may be substantially the same as the diameter of the first insertion space 14.

[0072] Each of the pair of first rods 210 can bend toward the second rod 220. Thus, the first rod 210 and the second rod 220 can approach each other. Thus, the width of the slit 204 between the first rod 210 and the second rod 220 can be reduced. Here, the first stopper 211, the wing 212, and the second stopper 213 fixed to the first rod 210 can move toward the second rod 220 together with the first rod 210. The rod 200 can be formed of a material having high rigidity and elasticity. For example, the rod 200 can be formed of plastic.

[0073] Referring to FIG. 9, the first blade 310 can include a first blade fixer 315. The first blade fixer 315 can be formed at the lower end of the first blade 310. The first blade fixer 315 can protrude below the first blade body 311. The cross section of the first blade fixer 315 can have a non-circular shape. For example, the outer peripheral surface of the first blade fixer 315 can have a serration shape or an uneven shape that provides friction in the circumferential direction. Alternatively, the cross section of the first blade fixer 315 can have a cross-sectional shape such as a triangle or a quadrilateral.

[0074] The first rod head 232 can be provided with a first blade coupling groove 234 that opens upward inside. The first blade fixer 315 can be inserted and fixed into the first blade coupling groove 234. The inner peripheral surface 235 of the first rod head 232 can be formed in a shape corresponding to the outer peripheral surface of the first blade fixer 315. For example, the inner peripheral surface 235 of the first blade fixer 315 and the first rod head 232 can have a corresponding serration shape and can mesh with each other in the circumferential direction. The outer peripheral surfaces 235 of the first blade fixer 315 and the first blade coupling groove 234 mesh with each other and can prevent the relative movement of the first blade 310 with respect to the rod 200 based on the circumferential direction.

[0075] The pin 320 can include a pin body 323. The pin body 323 can extend longitudinally up and down. The pin body 323 can extend downward from the pin blade 321. The pin 320 can include a pin fixer 325. The pin fixer 325 can be formed on the lower side of the pin body 323. The cross section of the pin fixer 323 can have a non-circular shape. For example, the outer peripheral surface of the pin fixer 323 can have a serration shape or an uneven shape that gives friction in the circumferential direction. Alternatively, the cross section of the pin fixer 323 can have a cross-sectional shape such as a triangle or a quadrilateral.

[0076] The first blade 310 can be provided with a first blade hole 314 that opens upward. The outer peripheral surface of the first blade hole 314 can have a shape corresponding to the outer peripheral surface of the pin fixer 323. For example, the outer peripheral surface of the pin fixer 323 and the outer peripheral surface of the first blade hole 314 can have a corresponding serration shape and can mesh with each other in the circumferential direction. The outer peripheral surfaces of the pin fixer 325 and the first blade hole 314 mesh with each other and can prevent the relative movement of the pin 320 with respect to the rod 200 based on the circumferential direction.

[0077] Therefore, when the cleaning kit is rotated in the circumferential direction (see FIG. 26), the first blade 310 and / or the pin 320 can be prevented from rotating relative to the rod 200 in the circumferential direction, and the first blade 310 and / or the pin 320 can be fixed.

[0078] Referring to FIG. 10, the second blade 330 can include a second blade fixer 335. The second blade fixer 335 can be formed at the upper end of the second blade 330. The second blade fixer 335 can protrude above the second blade body 331. The cross-section of the second blade fixer 335 can have a non-circular shape. For example, the outer peripheral surface of the second blade fixer 335 can have a serration shape or an uneven shape that provides friction in the circumferential direction. Alternatively, the cross-section of the second blade fixer 335 can have a cross-sectional shape such as a triangle or a quadrilateral.

[0079] The second rod head 242 can be provided with a second blade coupling groove 244 that opens downward inside. The second blade fixer 335 can be inserted into and fixed in the second blade coupling groove 244. The inner peripheral surface 245 of the second rod head 242 can be formed in a shape corresponding to the outer peripheral surface of the second blade fixer 335. For example, the outer peripheral surfaces of the second blade fixer 335 and the inner peripheral surface 245 of the second rod head 242 can have corresponding serration shapes and can mesh with each other in the circumferential direction. The outer peripheral surfaces of the second blade fixer 335 and the second blade coupling groove 244 can mesh with each other to prevent the relative movement of the second blade 330 relative to the rod 200 in the circumferential direction.

[0080] Therefore, when the cleaning kit is rotated in the circumferential direction (see FIG. 34), the second blade 330 can be prevented from rotating relative to the rod 200 in the circumferential direction, and the second blade 330 can be fixed.

[0084] The frame 100 can include a second engaging portion 123. The second engaging portion 123 can be formed on the first inner wall 120a of the frame 100. The second engaging portion 123 can be formed by the lower end of the first inner wall 120a of the frame 100 sinking upward. A pair of second engaging portions 123 can be formed to face each other on both sides with the rod hole 104 as the center. The second engaging portion 123 can be formed at a position corresponding to the first engaging portion 121 in the vertical direction. The second engaging portion 123 can be located below the first engaging portion 121. The first engaging portion 121 and the second engaging portion 123 can be separated from each other by a predetermined distance in the vertical direction. The distance between the first engaging portion 121 and the second engaging portion 123 can be the same as or similar to the distance between the first stopper 211 and the second stopper 213 when they are separated from each other.

[0085] The frame 100 can include a slide groove 124. The slide groove 124 can be formed by the second inner wall 120b of the frame 100 sinking outward from the rod hole 104. The slide groove 124 can extend long in the vertical direction. The slide groove 124 can communicate with the rod hole 104. A pair of slide grooves 124 can be formed to face each other on both sides with the rod hole 104 as the center.

[0086] The frame 100 can include a third engaging portion 125. The third engaging portion 125 can be formed adjacent to the upper side of the slide groove 124. The third engaging portion 125 can be formed by bending from the upper end of the second inner wall 120b toward the rod hole 104. The third engaging portion 125 can protrude toward the rod hole 104. The third engaging portion 125 can be formed on both sides with the slide groove 124 interposed therebetween. A pair of third engaging portions 125 can face each other with the rod hole 104 as the center.

[0087] Referring to FIGS. 13 to 15, the rod 200 can be coupled to or supported by the frame 100. The rod 200 can penetrate through the rod hole 104 of the frame 100 and protrude vertically from the frame 100. A part of the periphery of the rod 200 can be surrounded by the inner wall 120 of the frame 100. The rod 200 can be supported by the inner wall 120 of the frame 100. The first cap 410 and / or the second cap 430 can be coupled to the frame 100. The upper end of the rod 200 can be disposed inside the first cap 410. The lower end of the rod 200 can be disposed inside the second cap 430.

[0088] The edge of the second rod 220 can be inserted into the slide groove 124. The edge of the second rod 220 can be supported by the second inner wall 120b of the frame 100 from the slide groove 124. Both side edges of the second rod 220 and the second rod 220 can extend long in the vertical direction or the longitudinal direction.

[0089] The rod 200 can be located at a first position relative to the frame 100. The first position can be a state where the rod 200 does not move from the frame 100.

[0090] Referring to FIG. 13, the outer surface of the first rod 210 can be supported by the inner surface of the first inner wall 120a of the frame 100. The first stopper 211 can be supported by the second engaging portion 123. The first stopper 211 can be disposed below the second engaging portion 123. The wing 212 (see FIG. 7) can be supported by the inner surface of the first inner wall 120a.

[0091] Referring to FIGS. 14 and 15, both ends of the third stopper 221 can be supported by the third engaging portions 125 on both sides. The third stopper 221 can be disposed above the third engaging portion 125. The third engaging portion 125 can support both sides of the rod 200. Both ends of the fourth stopper 223 can be supported by the inner surface of the second inner wall 120b of the frame 100.

[0092] Therefore, the frame 100 can support the lower side of the third stopper 221 and the upper side of the first stopper 211 to fix the rod 200 in the vertical direction with respect to the frame 100. And the frame 100 can support while surrounding the rod 200 to fix the rod 200 in the horizontal direction with respect to the frame 100.

[0093] Referring to FIGS. 16 and 17, the first cap 410 can include a side wall 411 and an upper wall 412. The periphery of the first chamber 414 can be surrounded by the side wall 411 of the first cap 410. The upper part of the first chamber 414 can be covered by the upper wall 412 of the first cap 410. The lower part of the first chamber 414 can be open.

[0094] The pusher hole 4114 can be formed by the opening of the side wall 411 of the first cap 410. The pusher hole 4114 can communicate with the first chamber 414. A pair of pusher holes 4114 can face each other opposite to the center of the first chamber 414.

[0095] The positioning portion 413 can project downward from the inner surface of the upper wall 412 of the first cap 410 toward the first chamber 414. The positioning portion 413 can be arranged near the center of the upper wall 412. A pair of positioning portions 413 can face each other with respect to the center. The positioning portion 413 can be aligned with the position of the first blade 310 in the vertical direction. The lower surface of the positioning portion 413 can be recessed upward. The lower surface of the positioning portion 413 can include a shape corresponding to the upper surface of the first blade 310.

[0096] The pusher assembly 420 can include a first pusher 421 and a second pusher 422. The pusher assembly 420 can include a first pusher bar 425. The pusher assembly 420 can include a second pusher bar 426.

[0097] A pair of first pusher bars 425 can extend vertically long. The pair of first pusher bars 425 can be spaced apart from each other by a predetermined distance and can be arranged side by side. The second pusher bar 426 can be positioned between the pair of first pusher bars 425. The second pusher bar 426 can connect the upper ends of the pair of first pusher bars 425. The second pusher bar 426 can extend horizontally long. The first pusher bar 425 can extend downward long from the end of the second pusher bar 426.

[0098] The first pusher 421 can be adjacent to the lower end of the first pusher bar 425. The first pusher 421 can protrude from the outer surface of the first pusher bar 425 to the outside of the pusher assembly 420.

[0099] The second pusher 422 can be arranged at a position corresponding to the first pusher 421. The first pusher 422 can be adjacent to the lower end of the first pusher bar 425. The first pusher bar 425 can be arranged between the first pusher 421 and the second pusher 422. The second pusher 422 can face the first pusher 422 around the first pusher bar 425. The second pusher 422 can be adjacent to the end of the first pusher bar 425. The second pusher 422 can protrude from the inner surface of the first pusher bar 425 to the inside of the pusher assembly 420. The inner surface of the second pusher 422 can be formed to have a curvature. The inner surface of the second pusher 422 can be recessed in a concave shape. The inner surface of the second pusher 422 can correspond to the outer peripheral surface having the curvature of the first rod 210. The inner surface of the second pusher 422 can surround and be in close contact with one side of the outer peripheral surface of the first rod 210.

[0100] The rib 423 can protrude inward from the inner surface of the first pusher bar 425. The rib 423 can be disposed at a position corresponding to the first pusher 421. The rib 423 can extend from the inner surface of the first pusher bar 425 to the second pusher 422. The rib 423 can support the second pusher 422. The rib 423 can reinforce the rigidity of the second pusher 422. The rib 423 can be formed obliquely such that the width gradually becomes narrower toward the upper side.

[0101] The slot 424 can be formed by the opening of the second pusher bar 426. The slot 424 can be formed long in the longitudinal direction of the second pusher bar 426. The slot 424 can be formed at a position corresponding to the positioning portion 413.

[0102] The pusher assembly 420 can be inserted into the first chamber 414 which is inside the first cap 410. The first pusher 421 can penetrate the pusher hole 4114 and protrude outside the first cap 410. The second pusher 422 can protrude into the first chamber 414. The positioning portion 413 can penetrate the slot 424 and protrude below the slot 424.

[0103] The pusher assembly 420 can be supported by the first cap 410. The outer surface of the first pusher bar 425 can be supported by the inner surface of the side wall 411 of the first cap 410. The first pusher bar 425 can extend long along the side wall 411 of the first cap 410 to the upper wall 412 of the first cap 410. The upper surface of the second pusher bar 426 can be supported by the lower surface of the upper wall 412 of the first cap 410. The second pusher bar 426 can be fixed to the first cap 410.

[0104] The pusher assembly 420 can be formed of a material with good elasticity and rigidity. For example, the pusher assembly 420 can be formed of plastic. The pusher assembly 420 can have a restoring force. The first pusher 421 can move laterally from the pusher hole 4114. When the first pusher 421 is pushed toward the inside of the first cap 410, the first pusher bar 425 can tilt inwardly of the first cap 410 about the second pusher bar 426. The first pusher 421 and the second pusher 422 can move inwardly of the first cap 410 together with the first pusher bar 425. The distance between the pair of second pushers 422 can be narrowed. If the first pusher 421 is not pushed, the first pusher bar 425 can tilt outwardly of the first cap 410 about the second pusher bar 426 to restore the first pusher 421 and the second pusher 422 to their original positions.

[0105] Referring to FIGS. 18 to 22, the rod 200 can be movably coupled to the frame 100. The rod 200 can move in the longitudinal direction of the rod 200 relative to the frame 100. The rod 200 extends long in the vertical direction, and the rod 200 can move up and down relative to the frame 100. The rod 200 can move upward relative to the frame 100 from the first position (see FIG. 18) to the second position (see FIGS. 21 and 22). The manner in which the rod 200 is coupled to the frame 100 so as to be movable in the longitudinal direction of the rod 200 relative to the frame 100 is diverse. The following description is merely an example, and the manner in which the rod 200 moves is not limited thereto.

[0106] At the first position, the first stopper 211 can be supported by the second engaging portion 123 to fix the rod 200. At the second position, the first stopper 211 is supported by the first engaging portion 121, and the second stopper 213 is supported by the second engaging portion 123 to fix the rod 200. Thus, the first blade 310 and the pin 320 can be brought into a state where they can be used.

[0107] The height H2 from the bottom of the second insertion space 24 to the insertion port 44 may be higher than the height H1 of the first insertion space 14 (see FIG. 2). Therefore, by moving the rod 200 to the second position, the upper part of the rod 200 protrudes further upward from the frame 100, and the cleaning kit can be deformed so that the second insertion space 24 can be cleaned. Furthermore, the cleaning kit can be manufactured in a compact size.

[0108] Referring to FIGS. 18 and 19, when the first pusher 421 is pushed, the first pusher bar 425 tilts inward of the first cap 410 about the second pusher bar 426, and the first pusher 421 and the second pusher 422 can move inside the first cap 410.

[0109] Therefore, each of the pair of second pushers 422 can push each of the pair of first rods 210 toward the second rod 220. The pair of first rods 210 can bend in the thickness direction of the first rod 210 toward the second rod 220 with the first connecting portion 231 and the second connecting portion 241 as axes. The first rod 210 can bend into a concave shape inward. The width of the slit 204 can be narrowed.

[0110] The first stopper 211 can move together with the first rod 210 toward the second rod 220. The width between the pair of first rods 210 can be narrowed. The width between the pair of first stoppers 211 can be narrowed.

[0111] The first stopper 211 can move inside the second engaging portion 123 and the first inner wall 120a of the frame 100. The first stopper 211 can be in a state of not engaging with the second engaging portion 123.

[0112] Therefore, the first cap 410 can be separated upward from the frame 100, and the rod 200 can be grasped via the pusher assembly 420 and moved upward at the first position of the rod 200. The first coupling protrusion 115a can be disengaged from the first coupling groove 415. The first stopper 211 is supported inside the first inner wall 120a and can slide upward.

[0113] Referring to FIGS. 19 and 20, when the first cap 410 is moved upward while reducing the force pressing the first pusher 421, the first cap 410 can move upward with respect to the rod 200. Here, the second pusher 422 supports the first rod 210 and slides upward along the first rod 210, and the first cap 410 can move while being aligned with the rod 200. When the first cap 410 is moved upward while reducing the force pressing the first pusher 421, the second pusher 422 can be inserted into the recessed portion 233 during the movement.

[0114] Referring to FIGS. 20 and 21, when the second pusher 422 is inserted into the recessed portion 233 and engaged, the pusher assembly 420 can be free from the resistance of the restoring force of the first rod 210. Therefore, the rod 200 can be moved upward with respect to the frame 100 while relatively reducing the force pressing the first pusher 421. Of course, as another example, the rod 200 can also be moved upward with the first pusher 421 being pushed with the same force and the second pusher 422 not being inserted into the recessed portion 233.

[0115] When the rod 200 moves a predetermined distance and reaches the second position, the bent first rod 210 can be restored to a state parallel to the second rod 220. The first stopper 211 can be engaged with the first engaging portion 121. The second stopper 213 can be engaged with the second engaging portion 123. The outer peripheral surface of the first rod 210 between the first stopper 211 and the second stopper 213 can be supported by the first inner surface 120a of the frame 100.

[0116] Therefore, at the second position, the rod 200 can be fixed to the frame 100.

[0117] Referring to FIGS. 21 and 22, when the first pusher 421 is not pressed, the second pusher 422 inserted into the recess 233 can be disengaged from the recess 233. Therefore, with the rod 200 positioned at the second position, the first cap 410 can be separated from the rod 200, and the first blade 310 and the pin 320 can be exposed to the outside.

[0118] Referring to FIGS. 14 and 23, when the rod 200 moves from the first position to the second position, the second rod 220 can slide upward in the slide groove 124. The third stopper 221 can be disengaged upward from the third engaging portion 125. As the rod 200 moves, the second rod 220 can be supported by the second inner wall 120b of the frame 100 and the third engaging portion 125. Therefore, the rod 200 can be moved stably. At the second position, the disk 243 can be supported against the lower end of the inner surface 120 of the frame 100. Therefore, the upward movement of the rod 200 can be restricted.

[0119] Referring to FIGS. 15 and 24, the fourth stopper 223 can 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 can be supported by the second inner wall 120b of the frame 100 and slide upward. Therefore, the rod 200 can be moved stably.

[0120] At the first position, the third stopper 221 can be supported by the upper portion of the third engaging portion 125. At the second position, the third stopper 221 is disengaged from the third engaging portion 125, and the fourth stopper 223 can be supported against the lower portion of the third engaging portion 125. Therefore, the upward movement of the rod 200 can be restricted.

[0121] Referring to FIG. 25, in a state where the first cap 410 is separated from the frame 100, the rod 200, the first blade 310, and the pin 320 located at the second position can be inserted into the second insertion space 24 of the extractor 20.

[0122] The length from the upper end of the frame 100 to the end of the first blade 310 may be the same as or greater than the height H2 (see FIG. 2) from the bottom of the second insertion space 24 to the insertion port 44. With the upper parts of the first blade 310 and the rod 200 inserted into the second insertion space 24, the upper end of the frame 100 can be separated from the upper case 40. The end of the first blade 310 can contact the second flange 22 of the extractor 20. The pin 320 can be inserted into the through hole 23. The outer peripheral surface of the rod 200 and the second insertion space 24 may have corresponding cylindrical shapes. The through hole 23 can have a circular cross section.

[0123] Therefore, the user can rotate the first blade 310 and the pin 320 within the second insertion space 24 and clean the extractor 20 by grasping the frame 100 and / or the second cap 430 and rotating the cleaning kit in the circumferential direction.

[0124] Referring to FIGS. 26 to 28, when using an aerosol generating device and detaching the stick S (see FIG. 2) from the second insertion space 24 of the extractor 20, residues a1, a2, a3 of the aerosol or residues a1, a2, a3 leaked from the stick S may accumulate inside the extractor 20. Such residues a1, a2, a3 may become difficult to separate from the extractor 20 by solidifying while cooling in a state of sticking to the extractor 20 at a high temperature and becoming solids.

[0125] The first blade 310 can be inserted into the second insertion space 24 and move toward the second flange 22. The first blade edge 313 can contact the second flange 22. The pin 320 can penetrate through the through hole 23. The first blade 310 and the pin 320 can remove the residues a1, a2, a3 adhering to the extractor 20. The first blade 310 and the pin 320 can be formed of a metal that is more rigid than the solid-state residues a1, a2, a3.

[0126] When the pin 320 penetrates through the through hole 23, the first residue a1 adhering around the through hole 23 can be removed. Here, the remaining first residue a1 can be removed by scraping out the remaining first residue a1 when the pin blade 321 rotates circumferentially within the through hole 23. The maximum diameter D3 of the pin blade 321 can be the same as or similar to the diameter D4 of the through hole 23. Since the pin tip 322 is obliquely formed in a chamfer shape, even if the first residue a1 narrows the diameter D4 of the through hole 23, it can easily penetrate through the through hole 23 to remove the first residue a1.

[0127] The first blade 310 moves toward the second flange 22 and can collide with the second residue a2 and the third residue a3 adhering 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 to break down the second residue a2 and the third residue a3. The second residue a2 and the third residue a3 can be broken down into smaller pieces by repeating the above process. The first blade 310 located within the second insertion space 24 can rotate circumferentially in a state adjacent to or in contact with the second flange 22 to scrape out and break down the second residue a2 and the third residue a3 that have not been broken down. Therefore, the second residue a2 and the third residue a3 can be easily removed.

[0128] Referring to FIGS. 29 to 32, the first cap 410 can also be coupled to the frame 100 to push out the rod 200 to the first position and remove the second cap 430 from the frame 100. Thus, the second blade 330 can be made available for use.

[0129] Referring to FIGS. 29 and 30, with the rod 200 positioned at the second position, the first blade 310 and the pin 320 can be inserted into the first chamber 414 inside the first cap 410. Here, the lower surface of the positioning portion 413 can contact the first blade chamfer 312 (see FIG. 23). The lower surface of the positioning portion 413 can have an inclination substantially corresponding to the pair of first blade chamfers 312. The lower surface of the positioning portion 413 contacts the first blade chamfer 312 and can guide the positioning portion 413 to be aligned with the first blade chamfer 312.

[0130] Thus, the first cap 410 can be aligned in a fixed position with respect to the frame 100. Here, each of the pair of second pushers 422 can contact the outer peripheral surface of each of the pair of first rods 210. And the positions of the first coupling protrusion 115a and the first coupling groove 415 can be aligned in the vertical direction. Also, the positions of the first cap guide 117a and the first guide groove 417 can be aligned in the vertical direction.

[0131] Referring to FIGS. 30 and 31, with the first cap 410 aligned in a fixed position with respect to the frame 100, the first pusher 421 can be pushed inside the first cap 410. When the first pusher 421 is pushed, the first pusher bar 425 tilts inside the first cap 410 about the second pusher bar 426, and the first pusher 421 and the second pusher 422 can move inside the first cap 410.

[0132] Therefore, each of the pair of second pushers 422 can push each of the pair of first rods 210 toward the second rod 220. The pair of first rods 210 can bend in the thickness direction of the first rod 210 toward the second rod 220 around the first connecting portion 231 and the second connecting portion 241. The first rod 210 can bend inwardly in a concave shape. The width of the slit 204 can be narrowed.

[0133] The first stopper 211 can move together with the first rod 210 toward the second rod 220. The width between the pair of first rods 210 can be narrowed. The width between the pair of first stoppers 211 can be narrowed.

[0134] The first stopper 211 can move inside the first engaging portion 121 and the first inner wall 120a of the frame 100. The first stopper 211 can be in a state of not being engaged with the first engaging portion 121.

[0135] Therefore, by pushing the first cap 410 downward, the rod 200 in the second position can be moved downward. The first stopper 211 is supported inside the first inner wall 120a and can slide downward.

[0136] Referring to FIGS. 31 and 32, by pushing the first cap 410 downward, the rod 200 can be moved to the first position and the first cap 410 can be coupled to the frame 100. If the first pusher 421 is not pushed, the first stopper 211 can be engaged with and supported by the second engaging portion 123. The first stopper 211 can be supported by the second engaging portion 123 to limit the upward movement of the rod 200. The third stopper 221 (see FIG. 14) can be engaged with and supported by the third engaging portion 125. The third stopper 221 can be supported by the third engaging portion 125 to limit the downward movement of the rod 200. The first stopper 211 and the third stopper 221 can be supported by the frame 200 to fix the rod 200 to the frame 100.

[0137] When the second cap 430 is separated from the frame 100 with the rod 200 in the first position, the second blade 330 can be exposed to the outside. The lower end of the rod 200 and the second blade 330 can protrude long below the frame 100.

[0138] Referring to FIG. 33, with the second cap 430 separated from the frame 100, the rod 200 and the second blade 330 in the first position can be inserted into the first insertion space 14.

[0139] The length from the lower end of the frame 100 to the end of the second blade 330 may be the same as or greater than the height H1 (see FIG. 2) of the first insertion space 14. With the lower portions of the second blade 330 and the rod 200 inserted into the first insertion space 14, the lower end of the frame 100 can be separated from the body 100.

[0140] Therefore, the user can grasp the frame 100 and / or the first cap 410 and rotate the cleaning kit in the circumferential direction to rotate the second blade 330 within the first insertion space 14, so as to clean the inside of the first insertion space 14.

[0141] Referring to FIGS. 34 to 36, when using an aerosol generating device and detaching the stick S (see FIG. 2) from the second insertion space 24, residues a4, a5, a6 of the aerosol or residues a4, a5, a6 leaked from the stick S may accumulate inside the first insertion space 14. Such residues a4, a5, a6 adhere to the outer peripheral surfaces of the pipes 11, 12 and the heater assembly 30 in a high-temperature state and solidify while cooling to become solids, so they may become difficult to separate from the pipes 11, 12 and the heater assembly 30.

[0142] The second blade 330 can be inserted into the first insertion space 14 and move toward the first flange 12. The second blade edge 333 can contact the first flange 12. The heater assembly 30 can 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 (the inner peripheral surface of the second blade 330) can have corresponding shapes to each other. The second blade 330 can remove the residues a4, a5, a6 stuck to the pipes 11, 12 and the heater assembly 30. The second blade 330 can be formed of a metal that is more rigid than the residues a4, a5, a6 in a solid state.

[0143] When the heater assembly 30 is inserted into the second blade hole 334, the inner peripheral surface of the second blade 330 can scrape and remove the fourth residue a4 stuck to the outer peripheral surface of the heater assembly 30. The diameter D5 of the second blade hole 334 is the same as or similar to the diameter D6 of the heater assembly 30. Here, in order to rotate the cleaning kit to remove the remaining fourth residue a4, the inner peripheral surface of the second blade 330 can have an uneven shape such as a serration shape.

[0144] The second blade 330 can move toward the first flange 12 and collide with the fifth residue a5 and the sixth residue a6 stuck 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 to break down the fifth residue a5 and the sixth residue a6. The fifth residue a5 and the sixth residue a6 can be broken down into smaller pieces by repeating the above process. The second blade 330 located in the first insertion space 14 can rotate circumferentially in a state adjacent to or in contact with the first flange 12 to scrape and break down the fifth residue a5 and the sixth residue a6 that have not been broken down. Therefore, the fifth residue a5 and the sixth residue a6 can be easily removed.

[0145] The outer peripheral surface of the disk 243 can contact the inner peripheral surface of the first side wall 11 of the pipes 11 and 12. The outer peripheral surface of the second blade 330 can be spaced inwardly from the inner peripheral surface of the first side wall 11.

[0146] Therefore, the contact resistance against the second blade 330 is reduced, so that it can rotate easily. Also, damage to the pipes 11 and 12 and the second blade 330 can be reduced.
