[0046] According to one embodiment, the aerosol generating device 1 may include at least one of a battery 11, a control unit 12, and a sensor 13. At least one of the battery 11, control unit 12, and sensor 13 may be disposed inside the main body 10. The main body 10 may contain a cartridge 19 for generating aerosol. A user can hold the mouthpiece disposed at one end of the cartridge 19 in their mouth and inhale the aerosol.

[0047] According to one embodiment, the cartridge 19 may contain an aerosol-generating substance within its internal chamber 20. The aerosol-generating substance may be in any state, such as liquid, solid, gas, or gel. The aerosol-generating substance may comprise a liquid composition. For example, the liquid composition may be a liquid containing substances found in tobacco (including volatile tobacco flavor components) or a liquid containing non-tobacco substances.

[0048] In one embodiment, the cartridge 19 can be detachably coupled to the body 10. The cartridge 19 can be coupled to the body 10 by insertion into it. The body 10 can be configured to allow external air to flow into its interior when the cartridge 19 is inserted. At this time, the external air flowing into the body 10 can pass through the cartridge 19 and flow into the user's mouth.

[0049] In one embodiment, the cartridge 19 may include a chamber 20 containing aerosol-generating material. A liquid delivery means impregnated with the aerosol-generating material may be disposed inside the chamber 20. The liquid delivery means may include a core material, such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

[0050] In one embodiment, the heater 24 may be disposed within the cartridge 19 or the body 10. In the drawings, the heater 24 is shown disposed inside the cartridge 19, but is not limited thereto, and the heater 24 may also be disposed within the body 10 and separate from the cartridge 19. The heater 24 includes electrically conductive traces, which may be a coil structure wound around the liquid delivery means 25. Alternatively, the heater 24 may be configured to contact a portion of the liquid delivery means 25.

[0051] In one embodiment, heater 24 is capable of generating an aerosol. An aerosol is generated when liquid delivery means 25 is heated by heater 24. The generated aerosol is then inhaled into the user's mouth via airflow channel 23.

[0052] In one embodiment, the airflow channel 23 may be disposed in the cartridge 19. The airflow channel 23 may connect the atomizing space where the heater 24 or the liquid delivery means 25 is arranged and the outside of the cartridge. One end of the airflow channel 23 is open to the atomizing space where the heater 24 or the liquid delivery means 25 is arranged, and the other end of the airflow channel 23 may be connected to the mouthpiece 35.

[0053] For example, referring to FIG1, the airflow channel 23 may extend lengthwise along the length of the cartridge 19 from one side of the chamber 20 of the cartridge 19. For example, referring to FIG2, the airflow channel 23 may pass through the chamber 20 of the cartridge 19 and extend lengthwise along the length of the cartridge 19.

[0054] In one embodiment, battery 11 can supply the power required for the operation of components of aerosol generating device 1. Battery 11 can be referred to as a power source or power supply. Battery 11 can supply power to at least one of control unit 12, sensor 13, and heater 24.

[0055] In one embodiment, the control unit 22 can control the overall operation of the aerosol generating device 1. For example, the control unit 22 can control the operation of at least one of the battery 11, sensor 13, and cartridge 19.

[0056] In one embodiment, the control unit 12 may include at least one processor. The processor may be implemented as a plurality of gate arrays, or as a combination of a general-purpose microprocessor and a memory storing a program executable by the microprocessor. Alternatively, the at least one processor may be other forms 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. 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 the 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 operational state.

[0059] In one embodiment, the control unit 12 can analyze the detection results of the sensor 13 and control subsequent processes. For example, the control unit 12 can control the power supplied to the heater 24 based on the detection results of the sensor 13, thereby starting or stopping the heater 24.

[0060] In one embodiment, the control unit 12 can control the amount of power supplied to the heater 24 and the power supply time based on the detection results of the sensor 13, so that the heater 24 is heated to a predetermined temperature or maintained at a suitable temperature.

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

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

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

[0065] Hereinafter, any repetitive descriptions related to the above description will be omitted. It should be understood that in the aerosol generating apparatus 100, certain components and structures can be substituted, added, or omitted to the extent readily understood by those skilled in the art with reference to the accompanying drawings and the following description. Furthermore, unless it is clearly not technically feasible, at least one component or feature of the above embodiments can be incorporated into the aerosol generating apparatus 100.

[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 these components from external influences.

[0067] In one embodiment, at least one shell structure 111, 112 may be composed of two shell structures. For example, at least one shell structure 111, 112 may include a first shell structure 111 and a second shell structure 112.

[0068] However, in this document, terms such as "first" or "second" are used only to distinguish the corresponding component from other components and do not limit these components in any other way (e.g., in terms of importance or order). Furthermore, terms such as "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 together. For example, the first housing structure 111 may be the main body or main body portion of the aerosol generating device 100 (e.g., the main body 10 of FIG. 1 or FIG. 2). The second housing structure 112 may be a sub-body or a cartridge (e.g., cartridge 19 of FIG. 1 or FIG. 2).

[0070] In one embodiment, the cover 113 may surround at least a portion of the outer peripheral surfaces of the first housing structure 111 and the second housing structure 112. The cover 113 may be a separate component detachable from the first housing structure 111 and the second housing structure 112. Alternatively, the cover 113 may be a continuous component with the first housing structure 111. The cover 113 facilitates coupling between the first housing structure 111 and the second housing structure 112.

[0071] In one embodiment, the first housing structure 111 may 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, battery 105 provides the power required for the operation of each component of aerosol generating apparatus 100. Control unit 107 controls the operation of at least one component of aerosol generating apparatus 100.

[0073] In one embodiment, the heater module 120 may be disposed within the first housing structure 111. The atomizing space 115 may be disposed inside the first housing structure 111. The heater module 120 may be disposed within the atomizing space 115.

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

[0075] In one embodiment, the core material 121 may be disposed within the atomization space 115. One side of the core material 121 (e.g., the side along the +Z direction) may be at least partially exposed to one side of the first housing structure 111. The core material 121 may absorb liquid substances or aerosol-generating substances.

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

[0077] In one embodiment, heater 125 can be electrically connected to battery 105 via terminal 126. Heater 125 can receive power from battery 105 and generate heat. Heater 125 can be a resistance heater.

[0078] In one embodiment, the first housing structure 111 may be provided with a first aerosol channel 119 communicating with the atomization space 115. The first aerosol channel 119 may communicate with the outside of the first housing structure 111 from the atomization space 115. For example, as shown, the first aerosol channel 119 may be provided on at least one side of the heater module 120 (e.g., along the +Y direction or the -Y direction).

[0079] In one embodiment, the first aerosol channel 119 can transport the aerosol generated in the atomization space 115 to the outside of the first housing structure 111. For example, the first aerosol channel 119 can communicate with the second aerosol channel 129 of the second housing structure 112, thereby transporting the 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 passage 131 (e.g., airflow passage 23 of FIG. 1 or 2). The second housing structure 112 may store aerosol-generating substances in the chamber 127. The chamber 127 may be a liquid storage tank.

[0081] In one embodiment, the mouthpiece 130 may be disposed on one side of the second housing structure 112 (e.g., along the +Z direction). Alternatively, the mouthpiece 130 may cover the upper part of the second housing structure 112. The mouthpiece 130 may include an air inlet 135 communicating with the outside of the second housing structure 112.

[0082] In one embodiment, the airflow channel 131 may communicate with the second aerosol channel 129 and the air inlet 135. The airflow channel 131 may be physically separated from the chamber 127. The air inlet 135 may receive aerosol generated in the atomization space 115 from the airflow channel 131.

[0083] In one embodiment, the first housing structure 111 is detachably coupled to the second housing structure 112. For example, the second housing structure 112 is detachably inserted into one side of the first housing structure 111 (e.g., along the +Z direction). When the first housing structure 111 and the second housing structure 112 are coupled, the first aerosol channel 119 and the second aerosol channel 129 can communicate with each other.

[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 core material 121.

[0085] For example, when the first housing structure 111 and the second housing structure 112 are coupled, the core material 121 may be directly or indirectly connected to the chamber 127. For example, a portion of the absorption member 158 may be connected to the chamber 127, while another portion of the absorption member 158 (e.g., the underside or the surface in the -Z direction) may be connected to the core material 121.

[0086] In one embodiment, the core material 121 may receive and absorb aerosol-generating material from the second housing structure 112. The heater module 120 may heat the core material 121 that has absorbed the aerosol-generating material, thereby generating an aerosol within the atomization space 115.

[0087] In one embodiment, when the second housing structure 112 is coupled to the first housing structure 111, the second aerosol channel 129 and the first aerosol channel 119 can be interconnected. The user can hold the mouthpiece 130 in their mouth and inhale air through the air inlet 135. The aerosol formed in the atomization space 115 can sequentially pass through the first aerosol channel 119, the second aerosol channel 129, and the airflow channel 131, ultimately reaching the air inlet 135.

[0088] In one embodiment, the first housing structure 111 and the second housing structure 112 can be replaced independently. For example, the consumption cycle of the aerosol-generating material stored in the second housing structure 112 may differ from the corresponding replacement cycle of the first housing structure 111. The user can replace the second housing structure 112 individually, or the first housing structure 111 individually.

[0089] For example, the consumption cycle of aerosol-generating substances stored in the second housing structure 112 can be shorter than the appropriate replacement cycle of the first housing structure 111. While the second housing structure 112 requires multiple replacements, the first housing structure 111 may only need to be replaced once. By replacing only the second housing structure 112, users can extend the service life of the first housing structure 111, thereby reducing the replacement costs of some components.

[0090] In one embodiment, a first sealing member 151 may be disposed on the upper surface of the first housing structure 111 (e.g., the surface along the +Z direction). The first sealing member 151 may extend to one side (e.g., along 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 channel 119. The first aerosol channel 119 may communicate with the interior of the first housing structure 111 (e.g., the atomization space 115).

[0091] In one embodiment, the first sealing member 151 may be configured to enclose at least a portion of the core material 121. For example, the core material 121 may be disposed on one side of the first sealing member 151 (e.g., along the -Z direction). The first sealing member 151 may form above the atomization space 115.

[0092] In one embodiment, the housing 155 may be configured to enclose at least a portion of the core material 121. The housing 155 may be coupled to the first sealing member 151 to form an atomizing space 115 between the first sealing member 151 and the housing 155.

[0093] In one embodiment, terminal 126 may be disposed and fixed to the bottom of housing 155. Terminal 126 may protrude from housing 155 into atomizing space 115 and may be connected to heater 125 of heater module 120. A pair of terminals 126 may be provided, which are horizontally spaced apart.

[0094] In one embodiment, the heater 125 can be heated when the terminal 126 is energized. The heater 125 can be coupled to one side of the core material 121. For example, the heater 125 can be inserted into the bottom surface (e.g., the surface along the -Z direction) of the core material 121. When energized, the heater 125 can heat the core material 121.

[0095] In one embodiment, the heater 125 may form a pattern on the underside of the core material 121. For example, the heater 125 may form a pattern of multiple bends or extensions along the longitudinal direction (e.g., the X direction) of the core material 121.

[0096] In one embodiment, the core material 121 may be composed of a porous rigid body that absorbs aerosol-generating substances. For example, the core material 121 may be composed of porous ceramic. Compared to core materials made of cotton or resin materials, the core material 121 made of ceramic material has higher rigidity and heat resistance. The core material 121 may be made of a material with no change in shape or very little change in shape. Furthermore, the core material 121 made of ceramic material has excellent durability and service life, and can extend the replacement cycle of the first shell structure 111 coupled to the core material 121.

[0097] In one embodiment, the airflow inlet 155a may communicate with the outside of the first housing structure 111. The airflow inlet 155a may supply air to the atomizing space 115. The airflow inlet 155a may be formed at the bottom of the housing 155.

[0098] In one embodiment, multiple airflow inlets 155a may be formed, and they may be formed in a porous shape. The airflow inlets 155a may be spaced horizontally from the terminals 126. Alternatively, the airflow inlets 155a may be formed by opening the sidewall of the housing 155 and / or the sidewall of the first sealing member 151. A first aerosol channel 119 may be formed at a position facing the airflow inlets 155a.

[0099] In one embodiment, the first sealing member 151 may cover the top of the housing 155. The first sealing member 151 may be made of an elastic material. For example, the first sealing member 151 may be made of rubber or silicone material.

[0100] In one embodiment, the airflow inlet 155a and the first aerosol channel 119 can be arranged parallel to each other in two directions (e.g., along the Z-axis). For example, the airflow inlet 155a can be formed on the lower side of the atomization space 115. The first aerosol channel 119 can extend from the atomization space 115 in a direction facing the second housing structure 112. Air can enter the atomization space 115 through the airflow inlet 155a and be discharged to the outside of the atomization space 115 through the first aerosol channel 119. The aerosol generated by the heated core material 121 and the surrounding air can flow into the first aerosol channel 119.

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

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

[0103] In one embodiment, the chamber aperture 127a may communicate with the chamber 127. The chamber aperture 127a may be formed on one side of the chamber 127 (e.g., along the -Z direction). Aerosol-generating substances stored in the chamber 127 may be transported to the core material 121 through the chamber aperture 127a and the absorption member 158.

[0104] In one embodiment, the absorption member 158 may be disposed at the lower part of the chamber orifice 127a. The absorption member 158 can absorb aerosol-generating substances that pass through the chamber orifice 127a. For example, the absorption member 158 may be made of felt or cotton material.

[0105] In one embodiment, the absorbent member 158 may extend through the second sealing member 152. A portion of the absorbent member 158 (e.g., the face or underside along the -Z direction) may be exposed to the exterior of the second housing structure 112. The absorbent member 158 may protrude from the second housing structure 112 and connect to the core material 121. For example, when the first housing structure 111 and the second housing structure 112 are coupled, the absorbent member 158 and the core material 121 may be in contact with each other or opposite each other.

[0106] In one embodiment, a protective film is detachably attached to the underside of the absorbent member 158. The protective film may be made of a waterproof material. The protective film prevents aerosol-generating substances from leaking from the absorbent member 158. The user can remove the protective film from the absorbent member 158 before coupling the second housing structure 112 to the first housing structure 111.

[0107] In one embodiment, when the second housing structure 112 is coupled to the first housing structure 111, the second housing structure 112 can deliver aerosol-generating substances to the core material 121. For example, aerosol-generating substances stored in the chamber 127 can enter the absorption member 158 through the chamber opening 127a and be absorbed. The absorption member 158, having absorbed the aerosol-generating substances, can then contact the core material 121, thereby releasing the aerosol-generating substances. The aerosol-generating substances absorbed by the core material 121 can diffuse within the core material 121. The heater 125 can heat the aerosol-generating substances on the core material 121, thereby generating aerosols.

[0108] In one embodiment, the first sealing member 151 can seal a portion of the core material 121 protruding outward from the atomization space 115. When the second housing structure 112 is coupled to the first housing structure 111, the first sealing member 151 can seal the space 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 side (e.g., the side along the -Z direction) of the second housing structure 112 coupled to the first housing structure 111.

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

[0112] Referring to Figures 4a, 4b, 4c, 4d and 4e, an aerosol generating apparatus 100 according to one embodiment may include a first aerosol flow channel 119 and a second aerosol flow channel 129.

[0113] Hereinafter, any repetitive descriptions related to the above description will be omitted. It should be understood that in the aerosol generating apparatus 100, certain components and structures can be substituted, added, or omitted to the extent readily understood by those skilled in the art with reference to the accompanying drawings and the following description. Furthermore, unless it is clearly not technically feasible, at least one component or feature of the above embodiments can be incorporated into the aerosol generating apparatus 100.

[0114] In one embodiment, the first housing structure 111 may include a first aerosol channel 119. The first aerosol channel 119 may communicate with the outside of the first housing structure 111 from the atomization space 115. For example, the first aerosol channel 119 may transport aerosol generated in the atomization space 115 to a second aerosol channel 129 of the second housing structure 112.

[0115] In one embodiment, the second housing structure 112 may include a second aerosol channel 129. The second aerosol channel 129 may communicate with an air inlet 135 for discharging aerosols. For example, the second aerosol channel 129 may deliver aerosols from the first aerosol channel 119 in the first housing structure 111 to the air inlet 135.

[0116] In one embodiment, the absorption member 158 may include a protruding region 158a projecting 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 located inside the first housing structure 111.

[0117] In one embodiment, the absorber 158 may be made of felt or cotton material. The absorber 158 can absorb liquid aerosol generating material from the chamber 127 and transport it to the core material 121. The protruding region 158a may face or contact the core material 121, thereby allowing the liquid aerosol generating material to flow from the absorber 158 to the core material 121.

[0118] In one embodiment, the core material 121 may be made of ceramic or a porous thermally conductive material. The core material 121 may be heated by the heater 125 and atomize the liquid aerosol generating substance. The atomized aerosol from the core material 121 may diffuse into the atomization space 115.

[0119] In one embodiment of this disclosure, the protruding region 158a of the absorbing member 158 can reduce the volume of the core material 121, improve space utilization, and bring advantages to the manufacture of the aerosol generating device 100.

[0120] For example, considering the material properties of the absorbing component 158 ​​and the core material 121, the aerosol generating apparatus 100 can improve manufacturing economy and efficiency by reducing the volume of the core material 121 and increasing the volume of the absorbing component 158.

[0121] In one embodiment, the first aerosol channel 119 may extend in a direction (e.g., the +Z direction) that at least partially encompasses the protruding regions 158a of the core material 121 and the absorber member 158. For example, as shown in Figures 4b and 4c, the first aerosol channel 119 may extend in a direction (e.g., the +Z direction) that encompasses portions of both sides (e.g., the Y-axis direction) of the core material 121 and portions of both sides of the protruding regions 158a.

[0122] Alternatively, in one embodiment, the first aerosol channel 119 may be arranged adjoining with the protruding region 158a of the core material 121 and the absorber 158. Here, "arranged adjoining with a component" can mean arranged next to a component, arranged around a component, arranged parallel to a component, or arranged in the same direction as the extension direction of a component.

[0123] In one embodiment of this disclosure, since the first aerosol channel 119 is arranged in a direction surrounding the core material 121 and the absorption member 158, the aerosol generating apparatus 100 can improve space utilization or reduce the manufacturing difficulty of the core material 121.

[0124] For example, when the first aerosol channel 119 extends through the core material 121 or the absorber 158, openings or grooves need to be provided on the core material 121 and the absorber 158 to allow the first aerosol channel 119 to pass through. The first aerosol channel 119 can be located near the side of the core material 121 and the protruding region 158a, and surround the core material 121 and the protruding region 158a, thereby ensuring the autonomy and efficiency of the arrangement and structural design of the core material 121 and the absorber 158.

[0125] In one embodiment, the core material 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 absorption member 158. Alternatively, the first surface 121a may be a surface (or the top 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 where the heater 125 is located, or it may be a surface (or a lower surface) facing 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 surfaces 121c may be side surfaces (or lateral surfaces).

[0126] In one embodiment, the core material 121 may be hexahedral in shape. Alternatively, the core material 121 may be rectangular or elongated hexahedral in shape. For example, the plurality of third surfaces 121c may include a plurality of first side surfaces 121d and a plurality of second side surfaces 121e. The plurality of second side surfaces 121e may be disposed between the plurality of first side surfaces 121d, and their area may be larger than that of the plurality of first side surfaces 121d. However, this is only an example, and the core material 121 may be constructed from various geometric shapes. For example, the first surface 121a, the second surface 121b, and the plurality of third surface surfaces 121c may be continuous with each other in at least a partial region.

[0127] In one embodiment, the first aerosol channel 119 may extend along a direction surrounding at least one of a plurality of second side surfaces 121e. The first aerosol channel 119 having an elongated structure along the second side surface 121e provides higher aerosol delivery efficiency compared to the case where it extends around 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 a plurality of second side surfaces 121e. The plurality of second aerosol channels 129 may each surround a relatively wide second side surface 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 respectively disposed on both sides of the core material 121. The plurality of second aerosol channels 129 may be respectively connected to a plurality of first aerosol channels 119. The plurality of second aerosol channels 129 may transport aerosol received from the plurality of first aerosol channels 119 to the air inlet 135.

[0130] In one embodiment, the second aerosol channel 129 may include a first channel region 129a and a second channel region 129b. The first channel region 129a may be connected to the first aerosol channel 119. The first channel region 129a surrounds the absorption member 158 and may be bent at least once. The second channel region 129b may communicate from the first channel region 129a with the air inlet 135.

[0131] In one embodiment of this disclosure, the first flow channel region 129a may bend at least once and extend around multiple surfaces (e.g., sides and top) of the absorption member 158, thereby improving the space utilization and aerosol delivery efficiency of the aerosol generation device 100.

[0132] In one embodiment, the second aerosol channel 129 may include a plurality of first channel regions 129a. The plurality of first channel regions 129a may be respectively disposed on both sides of the absorber member 158. The second channel region 129b may be formed as a single channel. The plurality of first channel regions 129a may extend around multiple sides of the absorber member 158.

[0133] In one embodiment of this disclosure, the shape of the second aerosol channel 129 may be such that multiple first channel regions 129a converge into a second channel region 129b and extend to the air inlet 135. The multiple first channel regions 129a may be arranged around multiple sides of the absorption member 158, thereby improving the aerosol delivery efficiency of the second aerosol channel 129.

[0134] In one embodiment, the first housing structure 111 may include a first sealing member 151; 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 (e.g., rubber or silicone), a flexible material, or a waterproof material. The first sealing member 151 and the second sealing member 152 may be coupled to each other to seal the coupling area of ​​the first housing structure 111 and the second housing structure 112.

[0135] In one embodiment of this disclosure, since the first housing structure 111 and the second housing structure 112 are detachably coupled together, aerosol or liquid aerosol generating substances can leak from the coupling region to the outside. Alternatively, outside air or foreign matter can enter the interior of the aerosol generating device 100 through the coupling region. 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 face the second housing structure 112. The first housing structure 111 may partially enclose the protruding region 158a of the absorbing member 158. The first sealing member 151 may enclose the protruding region 158a, thereby preventing liquid aerosol generating substances from leaking through the protruding region 158a into an undesirable direction or onto an undesirable target.

[0137] In one embodiment, the second sealing member 152 may face the first sealing member 151. The second sealing member 152 may, together with the first sealing member 151, partially cover the protruding region 158a of the absorbent member 158.

[0138] For example, the first sealing member 151 and the second sealing member 152 can be configured to cover the side surface (e.g., the surface in the XY plane direction) of the protruding region 158a. The second sealing member 152 can be configured to cover the protruding region 158a and the core material 121, thereby facilitating the flow of liquid aerosol generating material from the protruding region 158a to the core material 121.

[0139] In one embodiment, the first sealing member 151 may include a first opening 119a. The first opening 119a may communicate with the first aerosol channel 119. The first opening 119a may be an outlet of the first aerosol channel 119. The first opening 119a may be provided on at least one side of the protruding region 158a of the absorption member 158.

[0140] In one embodiment, the second sealing member 152 may include a second opening 129c. The second opening 129c may communicate with the second aerosol channel 129. The second opening 129c may face each of the first openings 119a. The second opening 129c may be an inlet of the second aerosol channel 129.

[0141] In one embodiment, a first opening 119a may protrude from the first sealing member 151 and be inserted into the second opening 129c. Since the first opening 119a can be inserted into the second opening 129c, leakage of aerosol delivered from the first aerosol channel 119 to the second aerosol channel 129 to the outside can be reduced or prevented. Furthermore, coupling stability between the first housing structure 111 and the second housing structure 112 can be provided.

[0142] In one embodiment, the second opening 129c can be formed by protruding from the second sealing member 152 and inserted into the first opening 119a. Since the second opening 129c can be inserted into the first opening 119a, leakage of aerosol from the first aerosol channel 119 to the second aerosol channel 129 to the outside can be reduced or prevented. Furthermore, coupling stability between the first housing structure 111 and the second housing structure 112 can be provided. Additionally, referring to Figures 4d and 4e, when coupled with the second sealing member 152 such that the second sealing member 152 wraps around the outer peripheral surface of the first sealing member 151, the protruding shape of the second opening 129c can be positioned inside the outer peripheral surface of the second sealing member 152 to provide structural stability.

[0143] The embodiments of this disclosure described above, or other embodiments, are not mutually exclusive or distinct from each other. The constituent elements or functions of the embodiments of this disclosure described above, or other embodiments, can be used together or combined with each other.

[0144] For example, this means that component A illustrated in a particular embodiment and / or drawing can be combined with component B illustrated in other embodiments and / or drawings. That is, this means that even if the combination between components is not directly described, they can be combined except where it is stated that combination is impossible.
