[0049] In one embodiment, the cartridge (19) may include a chamber (20) for receiving an aerosol generating material. A liquid delivery means (25) for impregnating the aerosol generating material may be disposed inside the chamber (20). The liquid delivery means (25) may include a wick, such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

[0050] In one embodiment, the heater (24) may be disposed in the cartridge (19) or the body (10). Although the drawing illustrates that the heater (24) is disposed inside the cartridge (19), the present invention is not limited thereto, and the heater (24) may be disposed in the body (10) and be detachably disposed from the cartridge (19). The heater (24) may include an electrically conductive track, and the electrically conductive track of the heater (24) may be a coil structure that winds the liquid delivery means (25). Alternatively, the heater (24) may be formed in a structure that contacts a portion of the liquid delivery means (25).

[0051] In one embodiment, the heater (24) can generate an aerosol. As the liquid delivery means (25) is heated by the heater (24), an aerosol can be generated. The generated aerosol can be inhaled into the user's oral cavity through the airflow channel (23).

[0052] In one embodiment, an airflow channel (23) may be provided in the cartridge (19). The airflow channel (23) may communicate with the outside of the cartridge and an atomizing space in which a heater (24) or a liquid delivery means (25) is disposed. One end of the airflow channel (23) may be opened to the atomizing space in which the heater (24) or the liquid delivery means (25) is disposed, and the other end of the airflow channel (23) may be communicated with a mouthpiece (35).

[0053] For example, referring to FIG. 1, the airflow channel (23) may extend along the length of the cartridge (19) from one side of the chamber (20) of the cartridge (19). Or, for example, referring to FIG. 2, the airflow channel (23) may extend along the length of the cartridge (19) by penetrating the chamber (20) of the cartridge (19).

[0054] In one embodiment, the battery (11) can supply power to operate components of the aerosol generating device (1). The battery (11) can be a power source or power source. The battery (11) can supply power to at least one of the control unit (12), the sensor (13), and the heater (24).

[0055] In one embodiment, the control unit (12) can control the overall operation of the aerosol generating device (1). For example, the control unit (12) can control the operation of at least one of the battery (11), the sensor (13), and the cartridge (19).

[0056] In one embodiment, the control unit (12) may include at least one processor. The at least one processor may be implemented as an array of multiple logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory storing a program executable by the microprocessor. Furthermore, the at least one processor may be implemented as other types of hardware.

[0057] In one embodiment, the control unit (12) may include a memory. The memory may be operatively connected to at least one processor, and the memory may store executable instructions. The at least one processor may control the operation of the aerosol generating device (1) by executing the instructions stored in the memory.

[0058] In one embodiment, the control unit (12) can control the operation of a display, motor, etc. installed in the aerosol generating device (1). The control unit (12) can check the status of each component of the aerosol generating device (1) to determine whether the aerosol generating device (1) is in an operable state.

[0059] In one embodiment, the control unit (12) can analyze the results detected by the sensor (13) and control the processes to be performed thereafter. For example, the control unit (12) can control the power supplied to the heater (24) so ​​that the operation of the heater (24) is initiated or terminated based on the results detected by the sensor (13).

[0060] For example, the control unit (12) can control the amount of power supplied to the heater (24) and the time for which the power is supplied so that the heater (24) can be heated to a predetermined temperature or maintained at an appropriate temperature based on the result detected by the sensor (13).

[0061] In one embodiment, the sensor (13) may include at least one of a temperature sensor, a puff sensor, a cartridge detection sensor, and a motion detection sensor. For example, the sensor (13) may sense at least one of the temperature of the heater (24), the temperature of the battery (11), and the temperature inside and outside the body (10).

[0062] For example, the sensor (13) can sense the user's puff. For example, the sensor (13) can sense whether the cartridge is mounted. For example, the sensor (13) can sense the movement of the aerosol generating device (1).

[0064] Referring to FIGS. 3a, 3b, 3c and 3d, an aerosol generating device (100) according to one embodiment (e.g., the aerosol generating device (1) of FIG. 1 or 2) may include at least one housing structure (111, 112).

[0065] Hereinafter, any content that overlaps with the above-described content will be omitted for explanation, and it is to be understood that some components and structures of the aerosol generating device (100) may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one component or feature of the embodiments described above may be combined in the aerosol generating device (100) unless it is technically clearly impossible.

[0066] In one embodiment, at least one housing structure (111, 112) may form the exterior of the aerosol generating device (100). Alternatively, at least one housing structure (111, 112) may house other components of the aerosol generating device (100) internally and protect them from the exterior.

[0067] In one embodiment, at least one housing structure (111, 112) may be formed of two housing structures, for example, at least one housing structure (111, 112) may include a first housing structure (111) and a second housing structure (112).

[0068] However, in this document, terms such as "first," "second," or "first" or "second" may be used simply to distinguish one component from another and do not limit the components in any other respect (e.g., importance or order). Furthermore, "first" and "second" may be omitted, changed, or replaced as needed.

[0069] In one embodiment, the first housing structure (111) and the second housing structure (112) may be detachably coupled to each other. For example, the first housing structure (111) may be a main body or body portion (e.g., body (10) of FIG. 1 or 2) of the aerosol generating device (100). The second housing structure (112) may be a sub-body or cartridge (e.g., cartridge (19) of FIG. 1 or 2).

[0070] In one embodiment, the cover (113) can surround at least a portion of the outer circumferential surface of the first housing structure (111) and the second housing structure (112). The cover (113) can be a separate, separate component from the first housing structure (111) and the second housing structure (112). Alternatively, the cover (113) can be a continuous component with the first housing structure (111). The cover (113) can assist in the coupling of the first housing structure (111) and the second housing structure (112).

[0071] In one embodiment, the first housing structure (111) can accommodate at least one of a battery (105) (e.g., battery (11) of FIG. 1 or 2), a control unit (107) (e.g., control unit (12) of FIG. 1 or 2), and a heater module (120) (e.g., heater (24) of FIG. 1 or 2).

[0072] In one embodiment, the battery (105) can supply power necessary for the operation of the components of the aerosol generating device (100). The control unit (107) can control the operation of at least one of the components of the aerosol generating device (100).

[0073] In one embodiment, the heater module (120) may be placed in the first housing structure (111). An atomizing space (115) may be provided inside the first housing structure (111). The heater module (120) may be placed in the atomizing space (115).

[0074] In one embodiment, the heater module (120) can heat the wick (121) and the heater (125). The heater (125) can be coupled to one side of the wick (121) (e.g., the side in the -Z direction) to heat the wick (121).

[0075] In one embodiment, the wick (121) may be placed in the atomizing space (115). One side of the wick (121) (e.g., the side in the +Z direction) may be at least partially exposed to one side of the first housing structure (111). The wick (121) may absorb a liquid substance or an aerosol generating substance.

[0076] In one embodiment, the terminal (126) may be electrically connected to the heater module (120). The terminal (126) may supply power to the heater module (120). The terminal (126) may be disposed within the first housing structure (111).

[0077] In one embodiment, the heater (125) may be electrically connected to the battery (105) via a terminal (126). The heater (125) may be powered by the battery (105) and may generate heat. The heater (125) may be a resistive heater.

[0078] In one embodiment, the first housing structure (111) may have a first aerosol passage (119) communicating with the atomizing space (115). The first aerosol passage (119) may be communicated from the atomizing space (115) to the exterior of the first housing structure (111). For example, as illustrated in the drawing, the first aerosol passage (119) may be arranged on at least one side (e.g., in the +Y direction or the -Y direction) of the heater module (120).

[0079] In one embodiment, the first aerosol passage (119) can transfer aerosol generated in the atomizing space (115) to the outside of the first housing structure (111). For example, the first aerosol passage (119) can be connected to the second aerosol passage (129) of the second housing structure (112) to transfer aerosol to the second housing structure (112).

[0080] In one embodiment, the second housing structure (112) may include at least one of a chamber (127) (e.g., chamber (20) of FIG. 1 or 2) and an airflow channel (131) (e.g., airflow channel (23) of FIG. 1 or 2). The second housing structure (112) may store an aerosol generating material in the chamber (127). The chamber (127) may be a storage tank.

[0081] In one embodiment, the mouthpiece (130) may be positioned on one side (e.g., in the +Z direction) of the second housing structure (112). Alternatively, the mouthpiece (130) may cover an upper portion of the second housing structure (112). The mouthpiece (130) may include an intake port (135) that communicates with the exterior of the second housing structure (112).

[0082] In one embodiment, the airflow channel (131) may be in communication with the second aerosol path (129) and the intake port (135). The airflow channel (131) may be physically partitioned from the chamber (127). The intake port (135) may receive aerosol generated in the atomization space (115) from the airflow channel (131).

[0083] In one embodiment, the first housing structure (111) can be detachably coupled to the second housing structure (112). For example, the second housing structure (112) can be detachably inserted into one side (e.g., in the + Z direction) of the first housing structure (111). When the first housing structure (111) and the second housing structure (112) are coupled, the first aerosol flow path (119) and the second aerosol flow path (129) can be mutually connected.

[0084] In one embodiment, when the second housing structure (112) is coupled to the first housing structure (111), the second housing structure (112) can supply the aerosol generating material stored in the chamber (127) to the wick (121).

[0085] For example, when the first housing structure (111) and the second housing structure (112) are combined, the wick (121) can be directly or indirectly connected to the chamber (127). For example, some areas of the absorbent member (158) can be connected to the chamber (127), and other areas of the absorbent member (158) (e.g., the lower surface or the surface in the -Z direction) can be connected to the wick (121).

[0086] In one embodiment, the wick (121) can receive and absorb an aerosol generating substance from the second housing structure (112). The heater module (120) can heat the wick (121) that has absorbed the aerosol generating substance to generate an aerosol in the atomizing space (115).

[0087] In one embodiment, when the second housing structure (112) is coupled to the first housing structure (111), the second aerosol passage (129) and the first aerosol passage (119) can be connected. A user can hold the mouthpiece (130) in his / her mouth and inhale air from the inlet (135). The aerosol formed in the atomizing space (115) can pass through the first aerosol passage (119), the second aerosol passage (129), and the airflow channel (131) and be delivered to the inlet (135).

[0088] In one embodiment, the first housing structure (111) and the second housing structure (112) can be replaced independently of each other. For example, the consumption cycle of the aerosol generating substance stored in the second housing structure (112) and the appropriate replacement cycle of the first housing structure (111) may be different. The user can separately replace only the second housing structure (112) or separately replace only the first housing structure (111).

[0089] For example, the consumption cycle of the aerosol generating material stored in the second housing structure (112) may be shorter than the appropriate replacement cycle of the first housing structure (111). When the second housing structure (112) is replaced multiple times, the first housing structure (111) may be replaced only once. By replacing only the second housing structure (112), the user can use the first housing structure (111) for a longer period of time, and the replacement cost of some components can be reduced.

[0090] In one embodiment, the first sealing member (151) may be disposed on an upper surface (e.g., a surface in the +Z direction) of the first housing structure (111). The first sealing member (151) may extend to one side (e.g., in the +Z direction). At least a portion of the upper surface of the first sealing member (151) may be open to form a first aerosol passage (119). The first aerosol passage (119) may be connected to an inner side of the first housing structure (111) (e.g., an atomizing space (115)).

[0091] In one embodiment, the first sealing member (151) may be arranged to surround at least a portion of the wick (121). For example, the wick (121) may be arranged on one side (e.g., in the -Z direction) of the first sealing member (151). The first sealing member (151) may form an upper surface of the atomizing space (115).

[0092] In one embodiment, the case (155) may be arranged to surround at least a portion of the wick (121). The case (155) may be coupled with the first sealing member (151) to form an atomizing space (115) between the first sealing member (151) and the case (155).

[0093] In one embodiment, the terminal (126) may be fixedly arranged on the bottom of the case (155). The terminal (126) may protrude from the case (155) toward the atomizing space (115) and be connected to the heater (125) of the heater module (120). The terminals (126) may be provided as a pair spaced horizontally from each other.

[0094] In one embodiment, the heater (125) can be heated when current is supplied by the terminal (126). The heater (125) can be coupled to one surface of the wick (121). For example, the heater (125) can be insert-coupled to the bottom surface (e.g., the surface in the -Z direction) of the wick (121). The heater (125) can heat the wick (121) when current is supplied.

[0095] In one embodiment, the heater (125) can form a pattern on the lower surface of the wick (121). For example, the heater (125) can form a pattern that is bent or extended multiple times along the longitudinal direction (e.g., X direction) of the wick (121).

[0096] In one embodiment, the wick (121) may be formed of a porous rigid body that absorbs aerosol-generating substances. For example, the wick (121) may be formed of porous ceramic. A wick (121) made of a ceramic material may have greater rigidity and heat resistance than a wick made of cotton or resin. The wick (121) may be formed of a material that does not deform or has minimal deformation. In addition, a wick (121) made of a ceramic material may have excellent durability and lifespan, and may increase the replacement cycle of the first housing structure (111) to which the wick (121) is coupled.

[0097] In one embodiment, the air inlet (155a) may be connected to the exterior of the first housing structure (111). The air inlet (155a) may supply air to the atomizing space (115). The air inlet (155a) may be formed at the bottom of the case (155).

[0098] In one embodiment, the air inlet (155a) may be formed in multiple numbers to form a multi-hole shape. The air inlet (155a) may be spaced apart horizontally from the terminal (126). Alternatively, the air inlet (155a) may be formed by opening a lateral wall of the case (155) and / or a lateral wall of the first sealing member (151). The first aerosol path (119) may be formed at a position facing the air inlet (155a).

[0099] In one embodiment, the first sealing member (151) may cover the upper surface of the case (155). The first sealing member (151) may be formed of an elastic material. For example, the first sealing member (151) may be formed of a rubber or silicone material.

[0100] In one embodiment, the airflow inlet (155a) and the first aerosol channel (119) may be arranged in parallel in both directions (e.g., in the Z-axis direction). For example, the airflow inlet (155a) may be formed at the lower side of the atomization space (115). The first aerosol channel (119) may extend from the atomization space (115) in a direction facing the second housing structure (112). Air may be introduced into the atomization space (115) through the airflow inlet (155a) and discharged to the outside of the atomization space (115) through the first aerosol channel (119). The aerosol generated when the wick (121) is heated and the air surrounding it may flow toward the first aerosol channel (119).

[0101] In one embodiment, the second sealing member (152) may be disposed on the lower surface (e.g., the surface in the -Z direction) of the second housing structure (112). The second sealing member (152) may be disposed to surround at least a portion of the first housing structure (111) and the first sealing member (151) when the first housing structure (111) and the second housing structure (112) are coupled.

[0102] In one embodiment, the second sealing member (152) may be a portion or a structure of the second housing structure (112). For example, the second sealing member (152) may be formed integrally with the lower surface of the second housing structure (112), and may be a portion surrounding the absorbent member (158) exposed to the lower surface of the second housing structure (112).

[0103] In one embodiment, the chamber hole (127a) may be in communication with the chamber (127). The chamber hole (127a) may be formed on one side (e.g., in the -Z direction) of the chamber (127). The aerosol generating material stored in the chamber (127) may be delivered to the wick (121) through the chamber hole (127a) and the absorbent member (158).

[0104] In one embodiment, an absorbent member (158) may be positioned at the bottom of the chamber hole (127a). The absorbent member (158) may absorb aerosol generating substances passing through the chamber hole (127a). For example, the absorbent member (158) may be made of felt or cotton.

[0105] In one embodiment, the absorbent member (158) may be disposed to penetrate the second sealing member (152). A portion of the absorbent member (158) (e.g., a surface in the -Z direction or a lower surface) may be exposed to the outside of the second housing structure (112). The absorbent member (158) may protrude from the second housing structure (112) and be connected to the wick (121). For example, when the first housing structure (111) and the second housing structure (112) are coupled, the absorbent member (158) and the wick (121) may contact or face each other.

[0106] In one embodiment, a protective film may be detachably attached to the lower surface of the absorbent member (158). The protective film may be made of a waterproof material. The protective film may prevent aerosol generating substances from leaking from the absorbent member (158). Before attaching the second housing structure (112) to the first housing structure (111), the user may remove the protective film from the absorbent member (158).

[0107] In one embodiment, when the second housing structure (112) is combined with the first housing structure (111), the second housing structure (112) can supply an aerosol generating substance to the wick (121). For example, the aerosol generating substance stored in the chamber (127) can pass through the chamber hole (127a) and be absorbed by the absorbent member (158), and the absorbent member (158) that has absorbed the aerosol generating substance can contact the wick (121) to deliver the aerosol generating substance. The aerosol generating substance absorbed by the wick (121) can diffuse inside the wick (121). The heater (125) can heat the aerosol generating substance in the wick (121) to generate an aerosol.

[0108] In one embodiment, the first sealing member (151) can seal a portion of the wick (121) that protrudes outward from the atomizing space (115). When the second housing structure (112) is coupled to the first housing structure (111), the first sealing member (151) can seal between the first housing structure (111) and the second housing structure (112).

[0109] In one embodiment, the second housing structure (112) may include a switching member (160). The switching member (160) may be formed on one surface (e.g., a surface in the -Z direction) of the second housing structure (112) that is coupled to the first housing structure (111).

[0110] In one embodiment, the switch (170) may be provided in the first housing structure (111). The receiving space (161) may be a portion of the first housing structure (111) for receiving the switch (170). The switch (170) may detect whether the first housing structure (111) and the second housing structure (112) are coupled.

[0111] FIG. 4a is a cross-sectional view of an aerosol generating device (100) according to one embodiment, FIG. 4b is a cross-sectional view of an aerosol generating device (100) according to one embodiment, FIG. 4c is a cross-sectional perspective view of an aerosol generating device (100) according to one embodiment, and FIGS. 4d and 4e are perspective views of some components of an aerosol generating device (100) according to one embodiment.

[0112] Referring to FIGS. 4a, 4b, 4c, 4d and 4e, an aerosol generating device (100) according to one embodiment may include a first aerosol path (119) and a second aerosol path (129).

[0113] Hereinafter, any content that overlaps with the above-described content will be omitted for explanation, and it is to be understood that some components and structures of the aerosol generating device (100) may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one component or feature of the embodiments described above may be combined in the aerosol generating device (100) unless it is technically clearly impossible.

[0114] In one embodiment, the first housing structure (111) may include a first aerosol flow path (119). The first aerosol flow path (119) may be connected from the atomizing space (115) to the exterior of the first housing structure (111). For example, the first aerosol flow path (119) may transfer aerosol generated in the atomizing space (115) to a second aerosol flow path (129) of the second housing structure (112).

[0115] In one embodiment, the second housing structure (112) may include a second aerosol passage (129). The second aerosol passage (129) may be connected to an intake port (135) that discharges aerosol. For example, the second aerosol passage (129) may transfer aerosol from a first aerosol passage (119) provided in the first housing structure (111) to the intake port (135).

[0116] In one embodiment, the absorbent member (158) may include a protruding region (158a) protruding from the second housing structure (112). The protruding region (158a) may be inserted into the first housing structure (111). For example, when the first housing structure (111) and the second housing structure (112) are coupled, the protruding region (158a) may be positioned on the inside of the first housing structure (111).

[0117] In one embodiment, the absorbent member (158) may be made of felt or cotton. The absorbent member (158) may absorb a liquid aerosol generating substance from the chamber (127) and transfer it to the wick (121). The protruding region (158a) may be positioned to face the wick (121) or to contact the wick (121), so that the liquid aerosol generating substance may move from the absorbent member (158) to the wick (121).

[0118] In one embodiment, the wick (121) may be made of ceramic or a porous thermoconductive material. The wick (121) is heated by a heater (125) and can atomize a liquid aerosol generating material. The aerosol generated by the wick (121) can spread into the atomization space (115).

[0119] In one embodiment of the present document, the protruding region (158a) of the absorbent member (158) can reduce the volume of the wick (121), improve space efficiency, and provide manufacturing advantages for the aerosol generating device (100).

[0120] For example, considering the material properties of the absorbent member (158) and the wick (121), the aerosol generating device (100) can provide manufacturing economy and efficiency by reducing the volume of the wick (121) and increasing the volume of the absorbent member (158).

[0121] In one embodiment, the first aerosol flow path (119) can be deployed in a direction (e.g., +Z direction) that at least partially surrounds the wick (121) and the protruding region (158a) of the absorbent member (158). For example, as illustrated in FIGS. 4b and 4c, the first aerosol flow path (119) can be deployed in a direction (e.g., +Z direction) that surrounds a portion of both side surfaces (e.g., surfaces in the Y-axis direction) of the wick (121) and a portion of both side surfaces of the protruding region (158a).

[0122] Alternatively, in one embodiment, the first aerosol path (119) may be deployed adjoining the wick (121) and the protruding region (158a) of the absorbent member (158). Here, deploying adjoining a component may mean deploying adjacent to the component, deploying surrounding the component, deploying parallel to the component, or deploying in the same direction as the direction in which the component extends.

[0123] In one embodiment of the present document, the aerosol generating device (100) can provide space efficiency or the manufacturing difficulty of the wick (121) can be improved by having the first aerosol path (119) unfold in a direction surrounding the wick (121) and the absorbent member (158).

[0124] For example, when the first aerosol flow path (119) extends through either the wick (121) or the absorbent member (158), the wick (121) and the absorbent member (158) must be provided with an opening or groove for the first aerosol flow path (119) to pass through. The first aerosol flow path (119) is arranged adjacent to the side surfaces of the wick (121) and the protruding region (158a) and is deployed to surround the wick (121) and the protruding region (158a), thereby ensuring autonomy and efficiency in the arrangement and structural design of the wick (121) and the absorbent member (158).

[0125] In one embodiment, the wick (121) may include a first surface (121a), a second surface (121b), and a plurality of third surfaces (121c). The first surface (121a) may face the protruding region (158a) of the absorbent member (158). Alternatively, the first surface (121a) may be a surface (or upper surface) facing the first housing structure (111). The second surface (121b) may be a surface opposite to the first surface (121a). Alternatively, the second surface (121b) may be a surface (or lower surface) facing the surface where the heater (125) is disposed or the atomization space (115). The plurality of third surfaces (121c) may be surfaces extending from the first surface (121a) to the second surface (121b). Alternatively, the plurality of third sides (121c) may be side sides (or lateral sides).

[0126] In one embodiment, the wick (121) may have a hexahedral shape. Alternatively, the wick (121) may have a rectangular or elongated hexahedral shape. For example, the plurality of third faces (121c) may include a plurality of first faces (121d) and a plurality of second faces (121e). The plurality of second faces (121e) may be positioned between the plurality of first faces (121d) and may have a larger area than the plurality of first faces (121d). However, this is merely an example, and the wick (121) may be formed of various geometrical structures. For example, the first face (121a), the second face (121b), and the plurality of third faces (121c) may be continuous with each other in at least some areas.

[0127] In one embodiment, the first aerosol channel (119) may extend in a direction surrounding at least one of the plurality of second side surfaces (121e). The first aerosol channel (119) may have an elongated structure along the second side surface (121e), thereby providing aerosol delivery efficiency compared to a case where the first aerosol channel (119) extends surrounding the first side surface (121d).

[0128] In one embodiment, the first housing structure (111) may include a plurality of first aerosol channels (119). The plurality of first aerosol channels (119) may extend in a direction surrounding each of the plurality of second side surfaces (121e). The plurality of second aerosol channels (129) may extend to surround each of the relatively wide second side surfaces (121e), thereby providing aerosol delivery efficiency.

[0129] In one embodiment, the second housing structure (112) may include a plurality of second aerosol channels (129). The plurality of second aerosol channels (129) may be arranged on each of the two sides of the wick (121). The plurality of second aerosol channels (129) may be connected to each of the plurality of first aerosol channels (119). The plurality of second aerosol channels (129) may provide aerosol received from the plurality of first aerosol channels (119) to the inlet (135).

[0130] In one embodiment, the second aerosol flow path (129) may include a first flow region (129a) and a second flow region (129b). The first flow region (129a) may be connected to the first aerosol flow path (119). The first flow region (129a) may surround the absorbent member (158) and may be bent at least once. The second flow region (129b) may be connected from the first flow region (129a) to the suction port (135).

[0131] In one embodiment of the present document, the first euro area (129a) is bent at least once and extends to surround multiple surfaces (e.g., side surfaces and upper surfaces) of the absorbent member (158), thereby providing space efficiency and aerosol delivery efficiency of the aerosol generating device (100).

[0132] In one embodiment, the second aerosol flow path (129) may include a plurality of first flow path areas (129a). The plurality of first flow path areas (129a) may be respectively positioned on opposite sides of the absorbent member (158). The second flow path area (129b) may be formed as a single flow path. The plurality of first flow path areas (129a) may extend to surround each of the plurality of side surfaces of the absorbent member (158).

[0133] In one embodiment of the present document, the second aerosol flow path (129) may have a shape in which a plurality of first flow path areas (129a) are combined at a second flow path area (129b) and extend to the suction port (135). The plurality of first flow path areas (129a) are arranged to surround each of the plurality of side surfaces of the absorbent member (158), thereby providing an aerosol delivery efficiency of the second aerosol flow path (129).

[0134] In one embodiment, the first housing structure (111) may include a first sealing member (151), and the second housing structure (112) may include a second sealing member (152). At least one of the first sealing member (151) and the second sealing member (152) may be made of an elastic material, a soft material, or a waterproof material, such as rubber or silicone. The first sealing member (151) and the second sealing member (152) may be coupled to each other to seal a joint area of ​​the first housing structure (111) and the second housing structure (112).

[0135] In one embodiment of the present document, since the first housing structure (111) and the second housing structure (112) are detachably coupled, an aerosol or a liquid aerosol-generating substance may leak to the outside from the coupling area. Alternatively, external air or foreign substances may enter the aerosol generating device (100) through the coupling area. The first sealing member (151) and the second sealing member (152) can stably seal the first housing structure (111) and the second housing structure (112) by preventing leakage and inflow.

[0136] In one embodiment, the first sealing member (151) may be positioned to face the second housing structure (112). The first housing structure (111) may partially surround the protruding region (158a) of the absorbent member (158). The first sealing member (151) may be positioned to surround the protruding region (158a), thereby preventing the liquid aerosol generating material from leaking in an undesired direction or to an undesired target through the protruding region (158a).

[0137] In one embodiment, the second sealing member (152) may be positioned to face the first sealing member (151). The second sealing member (152) may partially surround the protruding area (158a) of the absorbent member (158) together with the first sealing member (151).

[0138] For example, the first sealing member (151) and the second sealing member (152) may be arranged to surround a side surface (e.g., a surface in the XY plane direction) of the protruding area (158a). The second sealing member (152) may be arranged to surround the protruding area (158a) and the wick (121), thereby assisting the movement of a liquid aerosol generating substance from the protruding area (158a) to the wick (121).

[0139] In one embodiment, the first sealing member (151) may include a first opening (119a). The first opening (119a) may be in communication with the first aerosol passage (119). The first opening (119a) may be an outlet of the first aerosol passage (119). The first opening (119a) may be positioned on at least one of both sides of the protruding region (158a) of the absorbent member (158).

[0140] In one embodiment, the second sealing member (152) may include a second opening (129c). The second opening (129c) may be in communication with the second aerosol passage (129). The second opening (129c) may be positioned to face each of the first openings (119a). The second opening (129c) may be an inlet of the second aerosol passage (129).

[0141] In one embodiment, the first opening (119a) may be formed to protrude from the first sealing member (151) and be inserted into the second opening (129c). By forming the first opening (119a) in a shape to be inserted into the second opening (129c), it is possible to reduce or prevent aerosol transmitted from the first aerosol passage (119) to the second aerosol passage (129) from leaking to the outside. In addition, it is possible to provide joint stability of the first housing structure (111) and the second housing structure (112).

[0142] In one embodiment, the second opening (129c) may be formed to protrude from the second sealing member (152) and be inserted into the first opening (119a). By forming the second opening (129c) in a shape to be inserted into the first opening (119a), it is possible to reduce or prevent aerosol transmitted from the first aerosol passage (119) to the second aerosol passage (129) from leaking to the outside. In addition, it is possible to provide joint stability of the first housing structure (111) and the second housing structure (112). In addition, referring to FIGS. 4d and 4e, when the second sealing member (152) is coupled to the second sealing member (152) in a shape that surrounds the outer surface of the first sealing member (151), the protruding shape of the second opening (129c) can be provided on the inner side of the outer surface of the second sealing member (152) to provide structural stability.
