For example, the cover 310 can be provided at the upper end of the first container 210 at a position adjacent to the insertion space 214. For example, the cover 310 can be provided on the cap 300 at a position adjacent to the insertion space 214.

[0050] The cover 310 may be provided to be pivotable. The cover 310 may pivot to open and close the insertion space 214. The cover 310 may pivot toward the inside of the insertion space 214 to open the insertion space 214. The direction in which the cover 310 pivots to open the insertion space 214 may be referred to as a first direction. The cover 310 may pivot toward the outside of the insertion space 214 to close the insertion space 214. The direction in which the cover 310 pivots to close the insertion space 214 may be referred to as a second direction.

[0051] When an end of the stick 400 contacts the cover 310 and pushes the cover 310 out, the cover 310 can pivot in a first direction to open the insertion space 214. The stick 400 can push the cover 310 out and be inserted into the insertion space 214. When the stick 400 is removed from the insertion space 214, the cover 310 can pivot in a second direction to close the insertion space 214.

[0052] A spring 312 (see FIG. 12) may provide a resilient force to the cover 310 in the second direction. One end of the spring 312 may support the cover 310, and the other end of the spring 312 may support the top end or the cap 300 of the first container 210. The spring 312 may be wound around a pivot axis of the cover 310.

[0053] The cover 310 may be provided around the insertion opening 304 of the cap 300. The cover 310 may be pivotally provided on the cap 300. The cover 310 may be pivotally moved to open and close the insertion opening 304. The cover 310 may be pivoted in a first direction to open the insertion opening 304. The cover 310 may be pivoted in a second direction to close the insertion opening 304.

[0054] The stick 400 may be inserted into the insertion space 214 through the insertion opening 304 of the cap 300. When one end of the stick 400 contacts the cover 310 and pushes the cover 310 out, the cover 310 may pivot in a first direction to open the insertion space 214 and the insertion opening 304. The stick 400 may be inserted into the insertion space 214 through the insertion opening 304 by pushing the cover 310 out. When the stick 400 is removed from the insertion space 214, the cover 310 may pivot in a second direction to close the insertion space 214 and the insertion opening 304.

[0055] When the stick 400 is inserted into the insertion space 214, one end of the stick 400 is exposed to the outside of the cap 300, and the other end of the stick 400 may be disposed adjacent to and above the second chamber C2. A user may inhale air by holding the exposed end of the stick 400 in their mouth.

[0056] Air can flow into the inside of the aerosol generating device through the cap inlet 304a. The air flowing in from the cap inlet 304a can flow into the cartridge inlet 224. The air can flow into the inside of the cartridge 200 through the cartridge inlet 224. The air that has passed through the cartridge inlet 224 can flow into the second chamber C2 and flow toward the insertion space 214. The air can pass through the stick 400 along with the aerosol generated in the second chamber C2.

[0057] Therefore, by inserting the stick 400 into the insertion space 214 , the cover 310 can be pivoted, thereby opening the insertion space 214 .

[0058] Furthermore, when the stick 400 is removed from the insertion space 214, the cover 310 pivots at the same time, so that the insertion space 214 can be automatically closed.

[0119] Therefore, the liquid in the second chamber C2 can be prevented from passing through the cartridge inlet 224 and leaking to the outside of the cartridge 200.

[0120] The sealing member 250 may be disposed between the first chamber C1 and the second container 220. The sealing member 250 may surround and adhere to an edge of the first chamber C1. The sealing member 250 may be made of an elastic material. For example, the sealing member 250 may be made of a material such as rubber or silicone. The sealing member 250 may prevent liquid stored in the first chamber C1 from leaking from the first chamber C1 through gaps between components.

[0121] The sealing member 250 may include at least one of a first sealing portion 251 and a second sealing portion 252. The first sealing portion 251 may extend along the outer wall 211 of the first container 210. The first sealing portion 251 may surround an edge of the outer wall 211 of the first container 210. The first sealing portion 251 may be in close contact between the outer wall 211 of the first container 210 and the frame 240. The first sealing portion 251 may be in close contact between the outer wall 211 of the first container 210 and the first frame portion 241.

[0122] Therefore, the liquid stored in the first chamber C1 can be prevented from leaking through the gap between the outer wall 211 of the first container 210 and the frame 240.

[0123] The second sealing portion 252 may extend from the first sealing portion 251 along the inner wall 212 of the first container 210. The second sealing portion 252 may surround and be in close contact with an edge of the inner wall 212 of the first container 210. The second sealing portion 252 may be in close contact between the inner wall of the first container 210 and the frame 240. The second sealing portion 252 may be in close contact between the inner wall of the first container 210 and the second frame portion 242. The second sealing portion 252 may be inserted into the frame 240. The second sealing portion 252 may be inserted into the second frame portion 242. A lower end of the inner wall 212 of the first container 210 may press the second sealing portion 252 toward the frame 240.

[0124] Therefore, the liquid stored in the first chamber C1 can be prevented from leaking through the gap between the inner wall 212 of the first container 210 and the frame 240.

[0125] The mount 130 may include a sensor receiving portion 137. The sensor receiving portion 137 may provide a space formed at the bottom of one side wall of the mount 130. The second sensor 180 may be received inside the sensor receiving portion 137. The lower case 230 may cover the sensor receiving portion 137. The lower case 230 may surround one side of the sensor receiving portion 137. One side wall of the receiving portion 231 of the lower case 230 may face a side of the sensor receiving portion 137. The extension portion 232 of the lower case 230 may cover an upper portion of the sensor receiving portion 137.

[0126] A gap through which air can flow may be formed between the sensor receiving part 137 and the lower case 230. Air may pass between the sensor receiving part 137 and the lower case 230 and flow into the cartridge inlet 224. The second sensor 180 may sense the flow of air passing between the sensor receiving part 137 and the lower case 230 and flowing into the cartridge inlet 224.

[0127] 15 and 16, the cartridge 200 may include a stick stopper 217 protruding inward from the periphery of the insertion space 214 at a position adjacent to the other end or the lower end of the insertion space 214. The stick stopper 217 may protrude in a radially inward direction. The stick stopper 217 may be formed on the outer wall 211 and / or the inner wall 212 of the first container 210.

[0128] The stick stopper 217 may include a plurality of stick stoppers. The stick stopper 217 may include three stick stoppers. A plurality of stick stoppers 217 may be arranged along the periphery of the insertion space 214. The stick stoppers 217 may be arranged in the circumferential direction. The stick stoppers 217 may be arranged spaced apart from each other. The stick stopper 217 may have a rib shape or a ring shape extending in the circumferential direction along the periphery of the insertion space 214. The stick 400 may hang around the periphery of the stick stopper 217. The stick stopper 217 may have a shape that gradually widens toward the upper side.

[0129] Thus, when the stick 400 is inserted into the insertion space 214, the stick stopper 217 can contact the end of the stick 400 and thereby restrict the stick 400 from moving beyond the insertion space 214 into the second chamber C2.

[0130] In addition, the reduction in the amount of air flowing from the second chamber C2 into the insertion space 214 can be minimized.

[0131] Furthermore, the stick stopper 217 does not prevent the aerosol generated in the second chamber C2 from extracting certain components from the medium of the stick 400.

[0132] 17 and 18, the pivot axis or shaft 311 of the cover 310 may be disposed above the insertion space 214. The pivot axis or shaft 311 of the cover 310 may be disposed between the insertion space 214 and the insertion opening 304. The cover 310 may pivot toward the inside of the insertion space 214 to open the insertion space 214 and / or the insertion opening 304. The direction in which the cover 310 pivots toward the inside of the insertion space 214 may be defined as a first direction.

[0133] When the cover 310 pivots in the first direction to open the insertion space 214, the cover 310 may be accommodated in the cover groove 215. When the cover 310 opens the insertion space 214, the cover 310 may be accommodated in the cover groove 215 and may overlap the inner wall 212 of the first container 210 located below the cover groove 215. When the cover 310 opens the insertion space 214, the cover 310 may be arranged parallel to the inner wall 212 of the first container 210 located below the cover groove 215.

[0134] The first guide 216 may be formed to be inclined from the bottom of the cover groove 215 toward the lower side of the insertion space 214. The first guide 216 may be formed to be inclined such that the insertion space 214 becomes gradually narrower as it goes downward. When the cover 310 opens the insertion space 214, the first guide 216 may be disposed adjacent to one end of the cover 310 on the lower side of the cover 310. When the cover 310 opens the insertion space 214, the first guide 216 may protrude into the insertion space 214 beyond the end of the cover 310.

[0135] The cover 310 may pivot toward the outside of the insertion space 214 to close the insertion space 214 and / or the insertion opening 304. The direction in which the cover 310 pivots toward the outside of the insertion space 214 may be defined as a second direction. One end of the spring 312 may support the cover 310, and the other end of the spring 312 may support the cap 300. The spring 312 may provide an elastic force to the cover 310 in a direction in which the cover 310 closes the insertion space 214. The cover 310 may pivot in the second direction via the spring 312.

[0136] The second guide 306 may be formed at an incline such that the inner space gradually narrows toward the lower side. The second guide 306 may be disposed adjacent to the pivot radius of the cover 310. The second guide 306 may be disposed outside the pivot radius of the cover 310. The second guide 306 may extend at an incline along the pivot radius of the cover 310.

[0137] One end of the second guide 306 may be located adjacent to the insertion opening 304. One end of the second guide 306 may be disposed outside the insertion opening 304. One end of the second guide 306 may be disposed below the insertion opening wall 305. The insertion opening wall 305 may protrude inward beyond the one end of the second guide 306. When the cover 310 pivots in the second direction to close the insertion space 214, the cover 310 can contact the insertion opening wall 305 to limit the movement of the cover 310.

[0138] The other end of the second guide 306 may be located adjacent to the insertion space 214. The other end of the second guide 306 may be located adjacent to the outer wall 211 of the first container 210 that defines the periphery of the insertion space 214. The other end of the second guide 306 may be disposed on the upper side of the outer wall 211 of the first container 210 that defines the insertion space 214. The second guide 306 may have a shape that extends obliquely from one end of the second guide 306 to the other end.

[0139] 19 to 22, the stick 400 can push the cover 310 inward or in a first direction of the insertion space 214. When the stick 400 is inserted into the insertion space 214 while pushing out the cover 310, the cover 310 can open the insertion space 214 and / or the insertion opening 304.

[0140] 19 and 20, when the end of the stick 400 passes through the insertion opening 304, the end of the stick 400 may contact the insertion opening wall 305. When the end of the stick 400 contacts the insertion opening wall 305, the insertion opening wall 305 can guide the stick 400 to a fixed position within the insertion opening 304. When the stick 400 passes through the insertion opening 304, the end of the stick 400 can push out the cover 310, causing the cover 310 to pivot in a first direction.

[0141] 20 and 21, when the stick 400 passes through the insertion opening 304, the cover 310 can be inserted into the cover groove 215. The cover 310 overlaps the inner wall 212 of the first container 210 and can form one side wall of the insertion space 214 together with the inner wall 212 of the first container 210.

[0142] 21 and 22, the stick 400 can be inserted into the insertion space 214 by sliding along the surface of the cover 310. The second guide 306 can be disposed on the opposite side of the pivot axis of the cover 310 with the insertion opening 304 as the center. The second guide 306 can be disposed on the opposite side of the cover groove 215. When the stick 400 is inserted into the insertion space 214, an end of the stick 400 can come into contact with the second guide 306. When the end of the stick 400 comes into contact with the second guide 306, the second guide 306 can guide the stick 400 to a fixed position in the insertion space 214.

[0143] The first guide 216 may be disposed at a position opposite to the second guide 306. The first guide 216 may be disposed below the second guide 216. The first guide 216 may be disposed below the cover groove 215. The first guide 216 may be disposed below the cover 310. The first guide 216 may extend in a circumferential direction along the inner wall 212 of the first container 210. When the stick 400 is inserted into the insertion space 214, the end of the stick 400 may contact the first guide 216. The end of the stick 400 may first contact the second guide 306 to be guided in position, and then contact the first guide 216. When the end of the stick 400 contacts the first guide 216, the first guide 216 can guide the stick 400 to a fixed position in the insertion space 214.

[0144] When inserted into the insertion space 214, the end of the stick 400 may come into contact with the stick stopper 217. The stick stopper 217 can contact the end of the stick 400 to restrict the stick 400 from moving downward in the insertion space 214 or into the second chamber C2.

[0145] Therefore, when a user pushes out the cover 310 using the stick 400, the stick 400 can smoothly pass through the insertion opening 304 and be guided to a correct position so as to push out the cover 310.

[0146] In addition, even if the stick 400 pushes out the cover 310 and the cover 310 is positioned inside the insertion space 214, the cover 310 is accommodated in the cover groove 215, so that the stick 400 can adhere closely to the wall that defines the insertion space 214.

[0147] In addition, since the stick 400 is in close contact with the wall partitioning the insertion space 214, unnecessary air flow between the insertion space 214 and the stick 400 is prevented when the user inhales air through the stick 400, thereby reducing wasted suction force and preventing a decrease in the efficiency of air flow.

[0148] In addition, when the user pushes out the cover 310 through the stick 400, the cover 310 can guide the stick 400 to be accurately inserted into the insertion space 214 even if an external force is applied to the end of the stick 400 in the second direction.

[0149] In addition, the stick 400 can be restricted from moving inside the second chamber C2.

[0337] An inner surface of the first flow guide 2318 may be connected to one side of the outer circumferential surface of the insertion space 214. The inner surface of the first flow guide 2318 may extend outwardly from the lower portion of the second chamber C2 toward one side of the lower end of the outer circumferential surface of the insertion space 214 in a rounded shape.

[0338] The chamber inlet 2424 may open toward the wick 261. The chamber inlet 2424 may be formed on a side of the wick 261. The chamber inlet 2424 may be formed in a part of the second inclined wall 2423. The chamber inlet 2424 may face the wick 261. The chamber inlet 2424 may overlap the wick 261. The wick 261 may be disposed between the chamber inlet 2424 and the first flow guide 2318. The wick 261 may be disposed below the insertion space 214.

[0339] The blocking wall 2314 may be located between the first sloping wall 2313 and the second sloping wall 2423. The support bar 2316 may be located between the blocking wall 2314 and the second sloping wall 2423. The support bar 2316 may support the second sloping wall 2423.

[0340] A side wall 2311 of the receiving portion 231' may support a side wall 2421 of the second frame 242'. A bottom 2312 of the receiving portion 231' may support a bottom 2421 of the second frame 242'.

[0341] The outer wall 211 of the first container 210 may be coupled to the peripheral portion 2322 of the lower case 230. The inner wall 212 of the first container 210 may press the second frame 242 downward toward the lower case 230. The lower case 230 may support the second frame 242. A portion of the bottom 2411 of the first frame 241 may be supported by the bottom 2311 of the extension portion 232'. The extension portion 232' may support the bottom 2411 of the first frame 241 between the engagement hook 2329 and the inner wall 212 of the first container 210.

[0342] The engagement hook 2329 can be inserted into the engagement groove 2419 and hooked onto the first frame 241. The engagement hook 2329 can protrude upward from the bottom 2321 of the extension 232'. The engagement hook 2329 can be disposed adjacent to an edge of the extension 232'. The engagement hook 2329 can protrude upward from the bottom 2321 of the extension 232 and have a hook shape that is bent in a predetermined direction. The first frame 241 and the engagement hook 2329 can receive a supporting force from each other in the vertical direction.

[0343] When the inner wall 212 of the first container 210 presses the second frame 242 downward toward the lower case 230, the first frame 241 connected to the second frame 242 can receive a deformation force such that the engagement groove 2419 is directed upward with respect to the extension 232' supporting the first frame 241. The first frame 241 can press the engagement hook 2329 upward. The engagement hook 2329 can support the first frame 241. The engagement hook 2329 can support the first frame 241 downward.

[0344] Therefore, during assembly of the cartridge 200', deformation of the frame 240 can be prevented, improving the structural stability of the cartridge 200'. Also, the number of locations using adhesive members can be minimized, improving the convenience of assembly of the cartridge 200'.

[0345] The pipe 212a may be defined by the inner wall 212 and the outer wall 211 of the first container 210 surrounding the insertion space 214. The first container 210 may be provided with a pipe 212a. The pipe 212a may surround the insertion space 214. The pipe 212a may be open in the vertical direction.

The first flow guide 2318 may be recessed on the outside of the second chamber C2 and extend roundly toward the insertion space 214. The first flow guide 2318 may cover the other side of the second chamber C2.

[0347] An inner surface of the first flow guide 2318 may be connected to a part of the outer circumferential surface of the insertion space 214. The inner surface of the first flow guide 2318 and the outer circumferential surface of the insertion space 214 may be flush with each other at their contact portions. The inner surface of the first flow guide 2318 and the outer circumferential surface of the insertion space 214 may form a continuous surface. A lower portion of the first flow guide 2318 may be located at a position lower than the height of the chamber inlet 2424. An upper portion of the first flow guide 2318 may be connected to one side of the outer wall 211 surrounding the insertion space 214. The other side portion of the second chamber C2 surrounded by the first flow guide 2318 may be located below the insertion space 214.

[0348] The second sloping wall 2423 may extend upward from the bottom of the second chamber C2. The second sloping wall 2423 may cover one side of the second chamber C2. The chamber inlet 2424 may be formed in a portion of the second sloping wall 2423.

[0349] The chamber inlet 2424 may open towards the wick 261. The chamber inlet 2424 may completely overlap with the wick 261. The chamber inlet 2424 may face the wick 261. The height difference W0 between the centre of the chamber inlet 2424 and the centre of the wick 261 may be 1 mm or less. The height difference W0 between the centre of the chamber inlet 2424 and the centre of the wick 261 may be 0.5 mm.

[0350] The chamber inlet 2424 may be located above the bottom of the second chamber C2. The wick 261 may be located above the bottom of the second chamber C2. The height H from the bottom of the second chamber C2 to the bottom end of the chamber inlet 2424 may be approximately the same as the height H from the bottom of the second chamber C2 to the bottom end of the wick 261. The height from the bottom of the second chamber C2 to the center of the wick 261 may be greater than the height from the bottom of the second chamber C2 to the center of the chamber inlet 2424. The height from the bottom of the second chamber C2 to the top end of the wick 261 may be greater than the height from the bottom of the second chamber C2 to the top end of the chamber inlet 2424. The chamber inlet 2424 may be located within the diameter W1 of the wick 261.

[0351] The width W2 of the chamber inlet 2424 may be smaller than the diameter W1 of the wick 261. The chamber inlet 2424 may taper off towards the second chamber C2 or the wick 261. The distance between the wick 261 and the chamber inlet 2424 may be the same as or similar to the width W2 of the chamber inlet 2424.

[0352] The center line L can be defined as an imaginary line passing through the center of the insertion space 214 in the longitudinal direction of the insertion space 214. The wick 261 can be disposed between the center line L and the chamber inlet 2424. The chamber inlet 2424 and the first flow guide 2318 can be located on opposite sides of the center line L. The wick 261 and the first flow guide 2318 can be located on opposite sides of the center line L. The wick 261 can be spaced apart from the center line L. The wick 261 overlaps the chamber inlet 2424 and the insertion space 214, but does not overlap the center line L.

[0353] The wick 261 may contact the chamber inlet 2424. The wick 261 may be positioned closer to the chamber inlet 2424 than to the first flow guide 2318. In cross-sectional view, the wick 261 may be positioned closer to an inner wall 212 of the first container 210 surrounding the insertion space 214 than to an outer wall 211 of the first container 210 surrounding the insertion space 214.

[0354] When the user inhales air through the stick 400, the air may flow into the second chamber C2 through the chamber inlet 2424. Liquid may be supplied to the wick 261 from the first chamber C1 and absorbed. When the heater 262 heats the wick 261 that has absorbed the liquid, an aerosol may be generated. The air flowing into the second chamber C2 through the chamber inlet 2424 may diffuse around the wick 261 and may come into contact with or pass through the wick 261.

[0355] Air that comes into contact with the wick 261 or passes through the wick 261 and carries the aerosol can flow above and below the wick 261. Air flowing above the wick 261 can flow into the insertion space 214. Air flowing below the wick 261 can flow toward the first flow guide 2318. A portion of the air flowing toward the first flow guide 2318 immediately flows toward the insertion space 214, and the remaining air can come into contact with the first flow guide 2318. The first flow guide 2318 can guide the air that comes into contact with the first flow guide 2318 to the insertion space 214.

[0356] Therefore, air can be discharged uniformly from the chamber inlet 2424 to the wick 261. In addition, since the air flowing into the second chamber C2 from the chamber inlet 2424 passes through the wick 261, the amount of aerosol accompanying the air can be increased. In addition, when the air flows into the second chamber C2 from the chamber inlet 2424 and flows toward the insertion space 214, the first flow guide 2318 can prevent the air from stagnating or forming a vortex. In addition, the first flow guide 2318 can guide the air that comes into contact with it to the insertion space 214.

[0357] A lower inner circumferential surface of the outer wall 211 of the first container 210 surrounding the insertion space 214 may include an outer wall inclined surface 218 that gradually widens in a radially outward direction toward the upper side. The outer wall inclined surface 218 may be formed obliquely outward so as to expand from the second chamber C2 toward the insertion space 214. The outer wall inclined surface 218 may be located above the first flow guide 2318.

[0358] Therefore, the air and aerosol flowing from the second chamber C2 into the insertion space 214 can be uniformly diffused onto the lower end surface of the stick 400 inserted into the insertion space 214.
