Referring to fig. 1, a heater 30 may be electrically connected to the battery 11. The heater 30 may generate heat when receiving current directly from the battery 11 without the need for the induction coil 35 (refer to fig. 2).

Referring to fig. 2, the aerosol-generating device 100 may comprise an induction coil 35. When the extractor 20 is inserted into the body 10, the induction coil 35 may surround the extractor 20 and the heater 30. The induction coil 35 may cause the heater 30 to generate heat. The heater 30 may be a susceptor. The heater 30 may generate heat due to a magnetic field generated by the alternating current flowing through the induction coil 35. The magnetic field may pass through the heater 30 to generate eddy currents in the heater 30. The current may cause the heater 30 to generate heat.

Referring to fig. 3 and 4, the body 10 may have an insertion space 14 defined therein. The insertion space 14 may be upwardly opened. The induction coil 35 may be wound around the insertion space 14. The extractor 20 may be removably inserted into the insertion space 14 through an opening in the insertion space 14. The insertion space 14 and the extractor 20 may have cylindrical shapes corresponding to each other. The extractor 20 may include a cylindrical interior.

The heater 30 may have a cylindrical body. The heater 30 may have a pointed upper end. The upper end of the heater 30 may be inserted into the rod 400 inserted into the cavity 224 in the second extractor 22. The induction coil 35 surrounding the insertion space 14 may cause the heater 30 to generate heat. Thus, the heater 30 may heat the rod 400 to generate an aerosol.

In another example, the heater 30 may receive power directly from a power source to generate heat without the need for the induction coil 35. In this case, the heater 30 may be in contact with a terminal formed on the bottom of the insertion space 14 via a terminal formed under the bottom 211 of the first extractor 21, and thus may be electrically connected to a power source.

Referring to fig. 5 and 6, the extractor 20 may include a first extractor 21 and a second extractor 22. The second extractor 22 may be coupled to the interior of the first extractor 21. The extractor 20 formed by the coupling between the first extractor 21 and the second extractor 22 may have a cylindrical shape. The second extractor 22 may be coupled to the first extractor 21 so as to be movable upward.

The first extractor 21 may have an upwardly open first cavity 214 defined therein. The first cavity 214 may be defined by the bottom 211 and the sidewall 212 of the first extractor 21.

The pair of side walls 212 of the first extractor 21 may extend longer. In another example, the sidewall 212 of the first extractor 21 may extend in a circumferential direction to surround the first cavity 214. Alternatively, the plurality of side walls 212 of the first extractor 21 may be arranged in the circumferential direction. The sidewall 212 of the first extractor 21 may be referred to as a first sidewall 212.

The second extractor 22 may be formed in a cylindrical shape. The second extractor 22 may have an upwardly open second cavity 224 defined therein. The second cavity 224 may have a cylindrical shape. The second cavity 224 in the second extractor 22 may be defined by a bottom 221 and a sidewall 222 of the second extractor 22. The bottom 221 of the second extractor 22 may have a disk shape or a bowl shape. The sidewall 222 of the second extractor 22 may extend upwardly from the bottom 221 of the second extractor 22. The sidewall 222 of the second extractor 22 may extend in a circumferential direction to surround the second cavity 224.

The third coupling portion 225b may be a magnet provided on the sidewall 222 of the second extractor 22 to generate an attractive force with the first coupling portion 215. In another example, the first coupling portion 215 may be a magnet disposed on the sidewall 222 of the second extractor 22, and the second and third coupling portions 225a and 225b may be magnets disposed on the sidewall 212 of the first extractor 21. The first coupling portion 215 may be detachably coupled to each of the second coupling portion 225a and the third coupling portion 225b using an attractive force generated therebetween. The first coupling portion 215 may be referred to as a first magnet 215. The second coupling portion 225a may be referred to as a second magnet 225a. The third coupling portion 225b may be referred to as a third magnet 225b.

The first coupling parts 215 may be formed in a pair, and the pair of first coupling parts 215 may be positioned opposite to each other. The second coupling parts 225a may be formed in a pair, and the pair of second coupling parts 225a may be positioned opposite to each other. The third coupling portions 225b may be formed in a pair, and the pair of third coupling portions 225b may be positioned opposite to each other. The third coupling portion 225b may be formed under the second coupling portion 225 a. However, the present disclosure is not limited thereto. At least one coupling portion may also be formed below the third coupling portion 225 b.

The sidewalls 212 of the first extractor 21 may be formed in a pair, and the pair of sidewalls 212 of the first extractor 21 may be positioned opposite to each other with respect to the first cavity 214. The pair of side walls 212 of the first extractor 21 may extend parallel to each other. Each of the pair of first coupling portions 215 may be formed on a corresponding one of the pair of side walls 212 of the first extractor 21. The pair of side walls 212 of the first extractor 21 may be formed to be pivotable inward and outward about the bottom 211 of the first extractor 21. Each of the pair of first coupling portions 215 may protrude inward from an upper portion of a corresponding one of the pair of side walls 212 of the first extractor 21.

The recess 226 may be formed in such a manner that the outer surface of the sidewall 222 of the second extractor 22 is recessed inward. The concave portion 226 may have a shape corresponding to the side wall 212 of the first extractor 21. The concave portion 226 may be elongated in an upward and downward direction. The concave portions 226 may be formed in a pair, and the pair of concave portions 226 may be positioned opposite to each other with respect to the second cavity 224. Each of the pair of concave portions 226 may be formed at a position corresponding to a corresponding one of the pair of side walls 212 of the first extractor 21. The recessed portion 226 may have an open underside. The recessed portion 226 may have a closed upper side. The sidewall 212 of the first extractor 21 may be inserted into the groove formed by the concave portion 226 to cover the concave portion 226. The side wall 212 of the first extractor 21 can slide upward and downward in the recessed portion 226. The concave portion 226 may guide the upward and downward sliding movement of the side wall 212 of the first extractor 21. The first coupling portion 215 may be formed in the recess portion 226. Alternatively, the second coupling portion 225a and the third coupling portion 225b may be formed in the recess portion 226.

The first guide portion 217 may be formed on a corner of an upper end of the sidewall 212 of the first extractor 21. The first guide portion 217 may be formed curvedly on a corner of the sidewall 212 of the first extractor 21. The second guide portion 227 may be curvedly formed on a corner of the open side of the recess portion 226. The sidewall 212 of the first extractor 21 may be guided by contact between the first guide portion 217 and the second guide portion 227 so as to be inserted into the recess portion 226.

Referring to fig. 7 to 9, a through hole 223 may be formed through the bottom 221 of the second extractor 22. The through holes 223 may be formed corresponding to the heater 30. The heater 30 may pass through the through hole 223. The heater 30 may protrude through the through hole 223 to the inside of the second cavity 224. Each of the through hole 223 and the heater 30 may have a circular cross section. The diameter of the through hole 223 may be larger than the diameter of the heater 30. When the heater 30 is inserted into the through hole 223, a gap may be formed between an inner circumferential surface of the second extractor 22 defining the bottom 221 of the through hole 223 and an outer circumferential surface of the heater 30.

The second extractor 22 may be coupled to the first extractor 21 so as to be movable upward and downward. The second extractor 22 may be located at a first position corresponding to the lowest position of the second extractor 22 relative to the first extractor 21 (refer to fig. 7). The second extractor 22 may be located at a second position corresponding to the uppermost position of the second extractor 22 relative to the first extractor 21 (refer to fig. 8). The second extractor 22 may be movable relative to the first extractor 21 from a first position to a second position or from the second position to the first position.

The second extractor 22 may be fixed at a first location and a second location. The second extractor 22 is movable between a first position and a second position. When the second extractor 22 is located at the first position, the bottom 211 of the first extractor 21 and the bottom 221 of the second extractor 22 may be adjacent to or in contact with each other. When the second extractor 22 is located at the second position, the bottom 211 of the first extractor 21 and the bottom 221 of the second extractor 22 may be positioned relatively far from each other.

In an example, the first coupling portion 215 may be formed on the first sidewall 212, and the second coupling portion 225a and the third coupling portion 225b may be formed on the second sidewall 222. When the second extractor 22 is located at the first position, the first coupling portion 215 may be coupled to the second coupling portion 225a, whereby the second extractor 22 may be fixed to the first extractor 21. When the second extractor 22 is pulled upward away from the first extractor 21 with a predetermined amount of force, the first coupling portion 215 coupled to the second coupling portion 225a may be separated from the second coupling portion 225 a. When the first coupling portion 215 is separated from the second coupling portion 225a, the second extractor 22 may be released and become movable upward with respect to the first extractor 21. The second extractor 22 is movable from a first position to a second position. When the second extractor 22 reaches the second position, the first coupling portion 215 may be coupled to the third coupling portion 225b, and thus the second extractor 22 may be fixed to the first extractor 21. When the second extractor 22 located at the second position is pushed down toward the first extractor 21, the first coupling portion 215 may be separated from the third coupling portion 225b, and the second extractor 22 may be moved toward the first position. When the second extractor 22 reaches the first position, the first coupling portion 215 may be coupled to the second coupling portion 225a, and thus the second extractor 22 may be fixed to the first extractor 21.

The first coupling portion 215 may be formed at a height corresponding to an upper portion of the heater 30. The third coupling portion 225b may be formed adjacent to the bottom 221 of the second extractor 22. When the second extractor 22 is located at the second position where the first coupling portion 215 is coupled to the third coupling portion 225b, the bottom 221 of the second extractor 22 may be located at a position corresponding to the upper portion of the heater 30 passing through the through hole 223.

Foreign substances generated from the stick 400 or the like may adhere to the bottom 221 of the second extractor 22 and the outer surface of the heater 30 and harden. With the above-described structure, foreign matter can be easily removed from the bottom 221 of the second extractor 22 and the outer surface of the heater 30. In addition, cleaning of the interior of the extractor 20 may be facilitated.

The coupling force between the first coupling portion 215 and the third coupling portion 225b may be greater than the coupling force between the first coupling portion 215 and the second coupling portion 225 a. Accordingly, the first coupling portion 215 and the third coupling portion 225b may be separated from each other without using a force pulling the second extractor 22 upward away from the first extractor 21, so as to separate the first coupling portion 215 and the second coupling portion 225a from each other.

The second extractor 22 located at the second position (refer to fig. 8) may be upwardly separated from the first extractor 21 (refer to fig. 9). When the second extractor 22 is located at the second position, the pair of side walls 212 of the first extractor 21 may pivot away from each other such that the first coupling portion 215 may be separated from the third coupling portion 225 b. Thus, the second extractor 22 may become separable upward from the first extractor 21. The second extractor 22 may be separate from the first cavity 214. The heater 30 may be separated from the through hole 223.

Therefore, each of the first extractor 21 and the second extractor 22 can be easily cleaned.

Meanwhile, the extractor 20 may include a first support 228. The first support 228 may protrude from an inner circumferential surface of the sidewall 222 of the second extractor 22 toward the second cavity 224. The first support 228 may be provided in plurality, and the plurality of first supports 228 may be arranged in the circumferential direction. An upper end of each of the first supports 228 may be inclined downward. A lower end of each of the first supports 228 may protrude upward from the bottom 221 of the second extractor 22.

Accordingly, the plurality of first supporters 228 may support the outer circumferential surface and the bottom of the rod 400 inserted into the second cavity 224, and a gap may be formed between the rod 400 and the second extractor 22 to allow air to flow through the gap. Accordingly, when the user holds the stick 400 in the mouth and sucks air, the air may be introduced into the lower portion of the stick 400 through a gap between the outer circumferential surface of the stick 400 and the inner circumferential surface of the sidewall 222 of the second extractor 22, and then may be delivered to the user through the stick 400 (see fig. 3).

Referring to fig. 10 to 13, the second support 229 may protrude outward from the outer circumferential surface of the extractor 20. The second support 229 may protrude outward from the outer circumferential surface of the first extractor 21 or the outer circumferential surface of the second extractor 22. The second support 229 may be formed on an upper end of the second extractor 22. The second support 229 may be provided in plurality, and the plurality of second supports 229 may be arranged to be spaced apart from each other in the circumferential direction. Accordingly, when the extractor 20 is inserted into the insertion space 24 in the main body 10, the extractor 20 may be supported by the second support 229. The second support 229 may form a gap between the outer circumferential surface of the extractor 20 and the sidewall defining the outer circumferential surface of the insertion space 24 to allow air to flow through the gap.

An inlet hole 218 may be formed in an outer circumferential surface of the bottom 211 of the first extractor 21 so as to communicate with the first cavity 214 in the first extractor 21. The inlet aperture 218 may be open in a lateral direction. The inlet hole 218 may be formed in plurality. The plurality of inlet holes 218 may be arranged in a circumferential direction.

When the second extractor 22 is located at the first position, the bottom 221 of the second extractor 22 may be spaced upwardly from the bottom 211 and/or the inlet aperture 218 of the first extractor 21. The stopper 219 may support the bottom 221 of the second extractor 22. The stopper 219 may be formed at a position higher than the inlet hole 218. The stopper 219 may protrude from the sidewall 212 of the first extractor 21 at a position higher than the inlet hole 218. Thus, a passage may be formed extending from the inlet aperture 218 to the through-hole 223.

Accordingly, when the user holds the wand 400 in the mouth and inhales air, air may be introduced into the inlet aperture 218 through the gap between the outer peripheral surface of the extractor 20 and the side wall defining the insertion space 24. Air introduced into the inlet hole 218 may be introduced into the lower portion of the wand 400 through the through-hole 223 and then may be delivered to a user through the wand 400.

Referring to fig. 13 and 14, the upper housing 40 may be coupled to the extractor 20. The upper housing 40 may be coupled to an upper end of the second extractor 22. The extractor 20 may be detachably coupled to the upper housing 40. The upper case 40 may have an insertion hole 44 formed therein to communicate with the opening of the second cavity 224.

The upper case 40 may be detachably coupled to the main body 10. The upper case 40 may cover an upper portion of the main body 10. The upper case 40 may cover the insertion space 24 and the periphery of the insertion space 24.

The extractor 20 may protrude downward from the upper housing 40. When the upper housing 40 is coupled to the main body 10, the extractor 20 may be inserted into the insertion space 24. When the upper case 40 is separated from the main body 10, the extractor 20 may be separated from the insertion space 24. The second extractor 22 may be located at the first position or the second position even in a state where the extractor 20 is coupled to the upper case 40. In a state where the second extractor 22 is coupled to the upper case 40, the first extractor 21 may be separated from the second extractor 22.

The upper case 40 may include a cap 45 for opening and closing the insertion hole 44. A cap 45 may be disposed on the insertion hole 44. The cap 45 may be mounted to be movable toward and away from the area above the insertion hole 44. When the cap 45 opens the insertion hole 44, the second cavity 224 may be opened so that the rod 400 may be inserted therein. The cap 45 may close the insertion hole 44 to prevent external foreign matters from entering the second cavity 224 and the insertion space 24.

Therefore, one side of the body 10 can be protected from the external environment. Furthermore, the introduction of external foreign matter into the main body 10 can be prevented. In addition, the extractor 20 can be more easily separated from the main body 10. In addition, foreign substances generated from the stick 400 or the like and adhered to the bottom 221 of the second extractor 22 and the outer surface of the heater 30 and hardened can be easily removed.
