[0052] Air flows into the cartridge 300 through the cartridge inlet 301 and can be discharged to the outside of the cartridge 300 through the cartridge outlet 304. The air that flows into the cartridge 300 passes through the inlet 302, the connecting hole 351, the chamber inlet 303, the second chamber C2, the chamber outlet 332, and the cartridge outlet 304 in sequence, and can be discharged to the outside.

[0053] When the heater 342 heats the wick 341, an aerosol may be formed in the second chamber C2 from the wick 341. Air passing through the cartridge 300 may be discharged from the second chamber C2 to the cartridge outlet 304, carrying the aerosol with it.

[0054] 7, the extension 140 may extend to one side from the upper portion of the pipe portion 120. The upper end surface 312 of the cartridge 300 may be covered by the extension 140.

[0055] The connecting channel 123 may be formed inside the upper body 120. The connecting channel 123 may be in communication with a lower end of the insertion space 124. The connecting channel 123 may extend downward from the lower end of the insertion space 124 and then bend to open outward. When the cartridge 300 is coupled to the upper body 120, the discharge port 323 may be inserted into the connecting channel 123. The cartridge outlet 304 may be in communication with the connecting channel 123. The connecting channel 123 may connect the cartridge outlet 304 and the insertion space 124.

[0056] Air can flow into the cartridge inlet 301 through the opening 201 of the upper case 200. The air that flows into the cartridge inlet 301 can flow into the second chamber C2 by sequentially passing through the inlet 302 and the chamber inlet 303. The air that flows into the second chamber C2 can be discharged to the outside of the cartridge 300 through the outlet 304, together with the aerosol generated around the core 341. The air discharged through the outlet 304 can be supplied to the insertion space 124 and the stick 400 inserted into the insertion space 124 through the connecting channel 123.

[0057] The sensor 80 may be provided inside the extension portion 140. The sensor 80 may face the top surface of the cartridge 300 or the cartridge inlet 301. The sensor 80 may be provided adjacent to the cartridge inlet 301. The sensor 80 may be located above the cartridge inlet 301. The sensor 80 may overlap with the cartridge inlet 301 in the up-down direction.

[0058] The sensor 80 can sense the flow of air in the surrounding area. The sensor 80 can be an air flow sensor or a pressure sensor. The sensor 80 can sense the flow of air based on changes in the surrounding air pressure. The extension 140 can have a hole for sensing the flow of air at a position adjacent to the cartridge inlet 301. The sensor 80 can be mounted on a substrate 81 disposed inside the extension 140 and electrically connected to the control unit 20 (see FIGS. 1 and 2). The control unit 20 (see FIG. 1) can control the operation of various components connected to the sensor 80 based on the air flow detected by the sensor 80.

[0059] Referring to FIG. 8 , the aerosol generating device may include a backflow prevention membrane 50. The backflow prevention membrane 50 may protrude inward from the outer circumferential surface of the connecting channel 123. The backflow prevention membrane 50 may extend in a circumferential direction along the outer circumferential surface of the connecting channel 123. One end of the backflow prevention membrane 50 may be fixed to the outer circumferential surface of the connecting channel 123. Both sides of the backflow prevention membrane 50 may be flat. The backflow prevention membrane 50 may be made of a material that is deformable and has elasticity and restoring force. For example, the backflow prevention membrane 50 may be made of a rubber or silicone material. The backflow prevention membrane 50 may be tiltable around the outer circumferential end of the backflow prevention membrane 50 fixed to the outer circumferential surface of the connecting channel 123.

[0060] 8(a), the backflow prevention membrane 50 may be located in a first position when separated from the discharge port 323. In the first position, the backflow prevention membrane 50 may have a flange shape or a ring shape. The backflow prevention membrane 50 may protrude in a direction perpendicular to the discharge port 323. The backflow prevention membrane 50 may protrude perpendicular to the periphery of the connecting channel 123.

[0061] Referring to FIG. 8(b), the backflow prevention membrane 50 pushed by the exhaust port 323 may be located in a second position. The exhaust port 323 may be inserted into the connecting channel 123. The end of the exhaust port 323 may push the backflow prevention membrane 50 in the direction in which the exhaust port 323 protrudes. The protruding direction of the exhaust port 323 may be the same as the direction in which the exhaust port 323 is inserted or the air flow direction. As the backflow prevention membrane 50 is pushed by the exhaust port 323, the air flow direction may be tilted in the direction in which air flows from the exhaust port 304. The backflow prevention membrane 50 may be formed such that the layer hole 54 gradually narrows in the air flow direction. When the exhaust port 323 is separated from the backflow prevention membrane 50, the backflow prevention membrane 50 may return to the first position (see FIG. 8(a)).

[0062] The backflow prevention membrane 50 may include a layer hole 54. The layer hole 54 may be surrounded by the inner circumferential edge of the backflow prevention membrane 50. The layer hole 54 may be in communication with the connecting channel 123. The layer hole 54 may expand as the backflow prevention membrane 50 moves from the first position to the second position. The width W22 or circumference of the layer hole 54 in the second position may be greater than the width W21 or circumference of the layer hole 54 in the first position. In the first position, the layer hole 54 appears smaller or non-existent. In the first position, the width W21 or circumference of the layer hole 54 may be smaller than the width W1 or circumference of the cartridge outlet 304. In the second position, the width W22 or circumference of the layer hole 54 may be smaller than the width W1 or circumference of the cartridge outlet 304.

[0063] Therefore, the air is guided to flow from the cartridge outlet 304 to the connecting flow path 123, and it is possible to prevent the air from flowing back from the connecting flow path 123 toward the cartridge outlet 304 (see FIG. 9).

[0064] In addition, when the cartridge 300 is separated from the body 100, the backflow prevention membrane 50 located at the first position can block external foreign matter from entering the connecting channel 123 and the insertion space .

[0065] The end surface 3231 of the discharge port 323 that contacts the backflow prevention membrane 50 may be inclined. The end surface 3231 of the discharge port 323 may be referred to as an inclined surface 3231. The inclined surface 3231 may have a circumference that gradually decreases toward the end (or tip).

[0066] 8(b), the inclined surface 3231 can support the backflow prevention membrane 50. In the second position, the inclination of the inclined surface 3231 and the inclination of the backflow prevention membrane 50 in the second position can correspond to each other. The backflow prevention membrane 50 can be in close contact with the inclined surface 3231 to form an inclination corresponding to the inclined surface 3231.

[0067] Therefore, the gap between the backflow prevention membrane 50 and the discharge port 323 is reduced, improving the efficiency of air flow. In addition, since the backflow prevention membrane 50 is fixed at a set or predetermined inclination, the structural safety of the backflow prevention membrane 50 can be improved.

[0068] The aerosol generating device may include a stopper 127. The stopper 127 may be formed around the connecting channel 123. One side of the stopper 127 may surround a portion of the connecting channel 123. The other side of the stopper 127 may face one side 321 of the second container 321 outside the connecting channel 123. The stopper 127 may be made of an elastic material. For example, the stopper 127 may be made of rubber or silicone.

[0069] When the cartridge 300 is coupled to the body 100 and the discharge port 323 is inserted into the connecting channel 123, one side of the stopper 127 may surround the discharge port 323. One side of the stopper 127 may be in close contact with the outer circumferential surface of the discharge port 323. One side of the stopper 127 may be in close contact with the side portion 321 of the second container 321 formed around the discharge port 323.

[0070] Therefore, the stopper 127 can adjust the depth to which the discharge port 323 is inserted into the connecting channel 123, and can adjust the inclination of the backflow prevention membrane 50 based on the adjusted insertion depth of the discharge port 323. In addition, the gap between the second container 321 and the stopper 127 is reduced, thereby improving the air flow efficiency.

[0071] 10, the backflow prevention membrane 500 may include a first part 510 and a second part 520. The backflow prevention membrane 500 may be made of a material that is deformable and has elasticity and restoring force. For example, the backflow prevention membrane 500 may be made of a rubber or silicone material.

[0072] The first part 510 may protrude inward from the outer circumferential surface of the connecting channel 123. The first part 510 may extend in a circumferential direction along the outer circumferential surface of the connecting channel 123. One end of the first part 510 may be fixed to the outer circumferential surface of the connecting channel 123. Both surfaces of the first part 510 may be flat. The first part 510 may be formed to be tiltable around the outer circumferential end of the first part 510 fixed to the outer circumferential surface of the connecting channel 123.

[0073] The second part 520 may extend from the first part 510. Both surfaces of the second part 520 may be flat. One end of the second part 520 may be fixed to the other end of the first part 510. The second part 520 may be formed to be tiltable around a portion between the first part 510 and the second part 520.

[0074] The layer hole 540 may be formed inside the backflow prevention membrane 500. The layer hole 540 may be in communication with the connecting channel 123. The layer hole 540 may be surrounded by the first part 510 and the second part 520. The first part 510 and the second part 520 may form predetermined angles θ21 and θ22 outside the layer hole 540. Outside the layer hole 540, the angles θ21 and θ22 between the first part 510 and the second part 520 may be less than 180 degrees.

[0075] 10(a), the backflow prevention membrane 500 separated from the discharge port 323 may be located in a first position. In the first position, the first part 510 may have a hollow truncated cone shape. In the first position, the first part 510 may extend from the periphery of the connecting channel 123 toward the opening of the connecting channel 123 at an angle. In the first position, the second part 520 may extend from the end of the first part 510 toward the opening of the connecting channel 123. In the first position, the second part 520 may face the discharge port 323. In the first position, the second part 520 may have a hollow cylindrical shape or a hollow truncated cone shape. An angle θ21 between the first part 510 and the second part 520 formed outside the layer hole 540 may be an obtuse angle.

[0076] 10(b), the backflow prevention membrane 500 pushed by the discharge port 323 may be located at a second position. The discharge port 323 may be inserted into the connecting channel 123. The end of the discharge port 323 may push the backflow prevention membrane 500 in the direction in which the discharge port 323 protrudes. Because the backflow prevention membrane 500 is pushed by the discharge port 323 and moves in the protruding direction of the discharge port 323, the backflow prevention membrane 500 may be supported by the discharge port 323 at the second position.

[0077] When the backflow prevention membrane 500 moves from the first position to the second position, the first part 510 may tilt around one end of the first part 510 fixed to the outer circumferential surface of the connecting channel 123. The second part 520 may tilt around the other end of the first part 510. When the backflow prevention membrane 500 moves from the first position to the second position, the distance between the first part 510 and the second part 520 may gradually narrow. At the second position, the angle θ22 between the first part 510 and the second part 520 formed outside the layer hole 540 may be an acute angle. The angle θ22 between the first part 510 and the second part 520 at the second position may be smaller than the angle θ21 between the first part 510 and the second part 520 at the first position.

[0078] The first part 510 faces the opening of the connecting channel 123 in the first position, and may be tilted such that angles θ11, θ12 between the first part 510 and the periphery of the connecting channel 123 increase toward the second position. The angle θ12 between the first part 510 and the periphery of the connecting channel 123 in the second position may be larger than the angle θ11 between the first part 510 and the periphery of the connecting channel 123 in the first position.

[0079] The first part 510 may have a flange shape or a ring shape at the first position of the backflow prevention membrane 500. The first part 510 may protrude in a direction perpendicular to the discharge port 323. The first part 510 may protrude perpendicular to the periphery of the connecting channel 123.

[0080] In the second position of the backflow prevention membrane 500, the second part 520 may be formed to be inclined in the air flow direction. In the second position, the second part 520 may be inclined such that the layer hole 540 gradually narrows in the air flow direction.

[0081] The backflow prevention membrane 500 may include a third part 530. The third part 530 may protrude perpendicularly from the end of the first part 510. The third part 530 may extend in the circumferential direction of the first part 510. At the first position, the third part 530 may protrude into the layer hole 540. At the first position, the third part 530 may have a flange shape or a ring shape. At the first position, the third part 530 may be formed perpendicular or obliquely to the discharge port 323. At the second position, the third part 530 may be formed parallel to the air flow direction. At the second position, the width W3 of the layer hole 540 surrounded by the third part 530 may be constant in the air flow direction. The width W3 of the layer hole 540 surrounded by the third part 530 may be smaller than the width W1 of the cartridge discharge port 304.

[0082] The aerosol generating device may include a supporter 550. The supporter 550 may protrude from the periphery of the connecting channel 123. The supporter 550 may be disposed adjacent to the first part 510, rearward of the first part 510, or downstream of the first part 510. When the backflow prevention membrane 500 is in the second position, the supporter 550 may support one surface of the first part 510. When the backflow prevention membrane 500 is in the second position, the supporter 550 may support a portion of the third part 530. The supporter 550 may limit movement of the first part 510 and fix the backflow prevention membrane 500 in the second position.

[0083] Therefore, the air is guided to flow from the cartridge ejection port 304 to the connecting flow path 123, and it is possible to prevent the air from flowing back from the connecting flow path 123 toward the cartridge ejection port 304 (see FIG. 11).

[0084] The aerosol generating device may include a stopper 127, the details of which are the same as those described above.

[0085] An end surface of the discharge port 323 may include an inclined surface 3232 and a pressing surface 3233. The inclined surface 3232 may be inclined so that the circumference gradually narrows in the direction in which the discharge port 323 protrudes. The inclination of the inclined surface 3232 and the inclination of the second part 520 in the second position may correspond to each other. The second part 520 may be in close contact with the inclined surface 3232, forming an inclination that corresponds to the inclined surface 3232.

[0086] The pressing surface 3233 may face the connecting channel 123. The pressing surface 3233 may be formed flat. The pressing surface 3233 may be perpendicular to the protruding direction of the discharge port 323. The pressing surface 3233 may press the second part 520 to move the second part 520 from the first position to the second position.

[0087] Therefore, the gap between the backflow prevention membrane 500 and the discharge port 323 is reduced, improving the air flow efficiency. In addition, since the backflow prevention membrane 500 is fixed so as to be inclined at a set or predetermined inclination, the structural safety of the backflow prevention membrane 500 can be improved.
