[0094] When the first frame space 2415 is connected to the second frame space 2425, a second chamber C2 can be formed. The second chamber C2 can be surrounded by the first frame body 2411 and the second frame body 2421. The chamber entrance 2414 can communicate with the second chamber C2. The connecting hole 2424 can communicate with the second chamber C2.

[0095] Core 246 can be installed in the second chamber C2. Core 246 can be connected to the first chamber C1. Liquid stored in the first chamber C1 can be supplied to core 246. When core 246, supplied with liquid, is heated by heater 247, aerosol can be formed in the second chamber C2. Air can be introduced into the second chamber C2 through cylinder inlet 234 and chamber inlet 2414. The air introduced into the second chamber C2 can mix with the aerosol generated in the second chamber C2 and can be supplied to insertion space 214 through connection hole 2424.

[0096] When the first part 210, the second part 220, and the third part 230 are connected to each other, the support member 250 can support the lower end of the tube 211. A washer 260 can be disposed or inserted between the lower end of the tube 211 and the support member 250. The tube 211 can press down on the support member 250.

[0097] The engaging portion 2112 may protrude from the lower end of the tube 211 toward the insertion space 214. The engaging portion 2112 may protrude from the inner circumferential surface of the tube 211 toward the insertion space 214.

[0099] The first frame 241 may be made of an elastic material. The second frame 242 may be made of an elastic material. The washer 260 may be made of an elastic material. The elastic material may be rubber.

[0100] The lower end of tube 211 can press down on washer 260. When washer 260 is pressed, it may deform due to its elasticity. Washer 260 may exert a downward force on support 250 due to its restoring force. The lower end of tube 211 and washer 260 can press down on support cap 252 near support port 253. The portion of support cap 252 near support port 253 may be shaped to face support space 255 (see...). Figure 11 The upper side of the first frame 241 and the second frame 242 deform downwards. The support member 250 can be pressed against the first frame 241, and the first frame 241 and the second frame 242 can be pressed downwards, so that the first frame 241 and the second frame 242 are pressed against each other. The support member 250 can be pressed against the upper end of the support wall 233. The support wall 233 can support the support member 250. The end of the core 246 can be in close contact with the first core groove 2416, the second core groove 2426, the third core groove 256, and the fourth core groove 2336.

[0101] Therefore, the first chamber C1, configured to store liquid therein, can be arranged around the rod 400 (see...). Figure 31 () and / or the supply rod 400 is inserted into the insertion space 214 therein, thereby improving the utilization efficiency of the space configured to store liquid therein.

[0102] Furthermore, since the distance between the rod 400 and the core 246 connected to the first chamber C1 and the heater 247 is reduced, the heat transfer efficiency of the aerosol can be improved.

[0103] In addition, it can prevent the liquid stored in the first chamber C1 from leaking into the second chamber C2 and the outside of the cylinder 200 through the gaps between the assembled components.

[0104] Furthermore, it can minimize the number of joint areas and components, and improve the ease of assembly.

[0105] In addition, the rigidity of the area connected to the cylinder 200 can be increased.

[0106] Reference Figure 18 The cylinder inlet 234 and the chamber inlet 2414 can be aligned with each other. The core 246 can be aligned with the connecting hole 2424. The connecting hole 2424 and the insertion space 214 can be aligned with each other.

[0107] The chamber may be misaligned with core 246. The chamber inlet 2414 may be misaligned with connection hole 2424. The chamber inlet 2414 may be misaligned with insertion space 214. The chamber inlet 2414 may be offset in one direction based on the second chamber C2. The chamber inlet 2414 may be offset toward post 140.

[0108] The chamber inlet port 2413 can extend upward from the bottom of the second chamber C2. The upper end of the chamber inlet port 2413 can be positioned above the bottom of the second chamber C2.

[0109] Therefore, it is possible to prevent droplets generated in the second chamber C2 from leaking out of the cylinder 200 through the cylinder inlet 234.

[0110] Furthermore, even when the user tilts the aerosol generating device including the cylinder 200 while performing a suction action, droplets can fall from the core 246 toward the bottom of the second chamber C2 and be collected on the bottom of the second chamber C2, thereby preventing droplets from moving to the chamber inlet 2414.

[0111] Reference Figure 17 and Figure 18 A portion of the insertion space 214 may extend outward to form a cover recess 215. The cover recess 215 may be adjacent to an opening in the upper end of the insertion space 214.

[0140] Core 246 can be installed in the second chamber C2. Core 246 can be connected to the first chamber C1. Core 246 can receive liquid from the first chamber C1. Heater 247 can heat core 246. Heater 247 can be installed in the second chamber C2. Heater 247 can be wound around core 246 multiple times. Heater 247 can be electrically connected to battery 190 and / or controller. Heater 247 can be a resistance coil. When heater 247 is activated to heat core 246, the liquid supplied to core 246 is atomized, thereby generating an aerosol in the second chamber C2.

[0141] A printed circuit board (PCB) assembly 150 may be mounted in post 140. PCB assembly 150 may include PCB 151. PCB assembly 150 may include a light source 153. PCB assembly 150 may include a first sensor 155. PCB assembly 150 may include a second sensor 157. Light source 153 may be mounted on PCB 151. First sensor 155 may be mounted on PCB 151. Second sensor 157 may be mounted on PCB 151. Light source 153, first sensor 155, and second sensor 157 may be mounted on a single PCB 151. PCB assembly 150 may extend along post 140.

[0142] The light source 153 can be installed in the column 140. The light source 153 can be mounted on the inner wall 141 of the column 140, facing the cylinder 200. The light source 153 can be positioned above the sensor receiving part 145. The light source 153 can provide light to the first chamber C1. The light source 153 can be an LED.

[0143] Therefore, even in the dark, the amount of liquid remaining in cylinder 200 and the condition of rod 400 can be checked (see...). Figure 31 ).

[0144] Furthermore, various designs for aerosol generation devices can be provided by means of light emitted from light source 153.

[0145] The first sensor 155 can be installed in the column 140 and the sensor receiving portion 145. The first sensor 155 can be installed on the upper part of the sensor receiving portion 145. The first sensor 155 can be positioned below the light source 153. The first sensor 155 can be oriented to face the insertion space 214. The first sensor 155 can be oriented to be tilted upwards.

[0146] The first sensor 155 can detect information about the cylinder 200. For example, the first sensor 155 can detect at least one of the following: information about changes in the remaining amount of liquid stored in the first chamber C1 of the cylinder 200; information about the type of liquid stored in the first chamber C1 of the cylinder 200; information about the rod 400 (see...). Figure 31 Information regarding whether the cylinder 200 is inserted into the insertion space 214 of the cylinder 200; information regarding the type of rod 400 inserted into the insertion space 214 of the cylinder 200; information regarding the amount of rod 400 used or remaining in the insertion space 214 of the cylinder 200; information regarding whether the cylinder 200 inserted into the insertion space 214 of the cylinder 200 is connected to the main body 100; and information regarding the type of cylinder 200 connected to the main body 100. Information regarding the cylinder 200 is not limited to this.

[0147] The first sensor 155 can detect changes in the electromagnetic properties of the cylinder 200, and therefore can detect information about the cylinder 200. The first sensor 155 can detect changes in the electromagnetic properties caused by adjacent objects. For example, the first sensor 155 can be a capacitive sensor. For example, the first sensor 155 can be a magnetic proximity sensor. The type of the first sensor 155 is not limited to these. For example, when the rod 400 is inserted into the insertion space 214 in the cylinder 200, or when the amount of liquid stored in the first chamber C1 changes, the electromagnetic properties detected by the first sensor 155 change, and the first sensor 155 can measure this change to detect information about the cylinder 200.

[0148] The second sensor 157 can be installed in the column 140 and the sensor receiving portion 145. The second sensor 157 can be installed on the lower part of the sensor receiving portion 145. The second sensor 157 can be positioned below the first sensor 155. The first sensor 155 can detect airflow. The second sensor 157 can detect the airflow introduced into the cylinder inlet 234. The second sensor 157 can be a pressure sensor or an airflow sensor. The second sensor 157 can face the side of the cylinder 200. The second sensor 157 can detect the airflow through the third channel P3, which communicates with the second channel P2. The second sensor 157 can be positioned upstream of the second chamber C2 and the cylinder inlet 234.

[0149] Therefore, various information about aerosol generating devices can be detected, and user convenience can be improved.

[0150] Reference Figure 26 and Figure 27 The cover 310 can open and close the insertion space 214. The cover 310 can open and close the opening through which the insertion space 214 is exposed to the outside. The cover 310 can be mounted adjacent to the opening of the insertion space 214. The cover 310 can be mounted adjacent to the upper end of the insertion space 214. For example, the cover 310 can be mounted on the first part 210 adjacent to the upper end of the insertion space 214. For example, the cover 310 can be mounted on the cap 300 adjacent to the upper end of the insertion space 214.

[0151] The cover 310 can be pivotally mounted. The cover 310 can pivot to open and close the insertion space 214. The cover 310 can pivot towards the inside or underside 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 can be referred to as a first direction. The cover 310 can pivot towards the outside or top side 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 can be referred to as a second direction.

[0152] The cover 310 can be mounted near the insertion opening 304 in the cap 300. The cover 310 can be pivotally mounted on the cap 300. The cover 310 can pivot to open and close the insertion opening 304. The cover 310 can pivot in a first direction to open the insertion opening. The cover 310 can pivot in a second direction to close the insertion opening 304.

[0153] Spring 312 can provide elastic force to cover 310 in a second direction. Spring 312 can support cover 310 at one end and support first part 210 or cap 300 at the other end. Spring 312 can be wound around pivot axis 311 of cover 310.

[0154] Reference Figures 28 to 31 When the end of the rod 400 contacts and pushes the cover 310, the cover 310 pivots in a first direction to open the insertion space 214. The rod 400 can be inserted into the insertion space 214 while pushing the cover 310. When the rod 400 separates from the insertion space 214, the cover 310 pivots in a second direction to close the insertion space 214.

[0155] A rod 400 can be inserted into an insertion space 214 through an insertion opening 304. When one end of the rod 400 contacts the cover 310 and thus pushes the cover 310, the cover 310 can pivot in a first direction to open the insertion space 214 and the insertion opening 304. The rod 400 can pass through the insertion opening 304 while pushing the cover 310. When the rod 400 is separated from the insertion space 214, the cover 310 can pivot in a second direction to close the insertion space 214 and the insertion opening 304.

[0156] When the rod 400 is inserted into the insertion space 214, one end of the rod 400 may be exposed outside the cap 300, and the other end of the rod 400 may be positioned directly above the second chamber C2. The user can inhale air while holding one end of the rod 400 in his / her mouth.

[0157] The cap 300 may include an insertion opening wall 305 forming the periphery of the insertion opening 304. The insertion opening wall 305 may have a circumferentially extending shape. The inner peripheral surface of the insertion opening wall 305 may surround the periphery of the insertion opening 304.

[0158] The inner circumferential surface of the insertion opening wall 305 can be circular. The inner circumferential surface of the insertion opening wall 305 can bulge inward toward the insertion opening 304 or be circular. The inner circumferential surface of the insertion opening wall 305 can move downward from top to bottom, narrowing and then widening.

[0159] The end or periphery of the cover 310 can engage with the underside of the insertion opening wall 305. When the cover 310 closes the insertion opening 304, the insertion opening wall 305 can contact the cover 310, thereby restricting the movement of the cover 310. In other words, the insertion opening wall 305 can contact the end or periphery of the cover 310, thereby restricting the upward pivoting movement of the cover 310 from the insertion opening 304. The cover 310 can have a size larger than the size of the insertion opening 304.

[0160] Reference Figure 28 and Figure 29 When the end of the rod 400 passes through the insertion opening 304, the end of the rod 400 can contact the insertion opening wall 305. When the end of the rod 400 contacts the insertion opening wall 305, the insertion opening wall 305 can guide the rod 400 to its normal position in the insertion opening 304. When the rod 400 passes through the insertion opening 304, the end of the rod 400 can push the cover 310, thereby causing the cover 310 to pivot in a first direction.

[0161] Reference Figure 29 and Figure 30 When the rod 400 passes through the insertion opening 304, the cover 310 can pivot in the first direction and can be received or inserted into the cover groove 215. At this time, the cover 310 can overlap with the tube 211.

[0162] Reference Figure 30 and Figure 31 The rod 400 can be inserted into the insertion space 214 while sliding along the surface of the cover 310. The second guide 217 can be positioned relative to the pivot axis of the cover 310 based on the insertion opening 304. The second guide 217 can also be positioned relative to the cover recess 215.

[0163] When the rod 400 is inserted into the insertion space 214, the end of the rod 400 can contact the second guide 217. When the end of the rod 400 contacts the second guide 217, the second guide 217 can guide the rod 400 to its normal position in the insertion space 214.

[0164] The first guide 216 may be positioned opposite the second guide 217. The first guide 216 may be positioned below the second guide 217. The first guide 216 may be located below the cover recess 215. The first guide 216 may be located below the cover 310. The first guide 216 may extend circumferentially along the inner circumferential surface of the tube 211. When the rod 400 is inserted into the insertion space 214, the end of the rod 400 may contact the first guide 216. The end of the rod 400 may first contact the second guide 217 for positioning, and then contact the first guide 216. When the end of the rod 400 contacts the first guide 216, the first guide 216 may guide the rod 400 to its normal position in the insertion space 214.

[0165] When rod 400 is inserted into insertion space 214, the end of rod 400 may contact rod stop 219. Rod stop 219 may contact the end of rod 400, thereby restricting rod 400 from moving downward beyond insertion space 214 or into second chamber C2.

[0166] Therefore, the rod 400 inserted into the insertion space 214 can pivot the cover 310, thereby opening the insertion space 214.

[0167] Furthermore, when the user pushes the cover 310 with the rod 400, the rod 400 can be guided to its normal position so that the rod 400 can pass smoothly through the insertion opening 304. Even when the cover 310 applies external force to the end of the rod 400 in the second direction, the rod 400 can be guided so that it can be precisely inserted into the insertion space 214.

[0168] Furthermore, even when the rod 400 pushes the cover 310, thereby positioning the cover 310 in the insertion space 214, the cover 310 can be received in the cover recess 215, allowing the rod 400 to make close contact with the wall defining the insertion space 214. Therefore, when the user draws air in through the rod 400, unnecessary airflow between the wall of the insertion space 214 and the rod 400 can be prevented.

[0169] In addition, the movement of rod 400 into the second chamber C2 can be restricted.

[0170] Furthermore, since the cover 310 pivots when the rod 400 is separated from the insertion space 214, the insertion space 214 can be automatically closed.

[0171] In addition, it can protect the interior of the insertion space 214 from external contaminants.

The mounting member 130 can be threaded onto the lower body 110.

[0173] A rib groove 136 may be formed in the outer surface 132 of the mounting member 130. The rib groove 136 may have a shape that causes the outer surface 132 of the mounting member 130 to be recessed inward. The rib groove 136 may have a shape that extends along the periphery of the outer surface 132 of the mounting member 130.

[0174] The main body rib 116 may have a shape that protrudes from the inner peripheral surface of the sidewall 111. The main body rib 116 may have a shape that extends along the inner peripheral surface of the sidewall 111 of the lower body 110. The main body rib 116 may be made of an elastic material. For example, the main body rib 116 may be made of rubber, silicone, etc. The main body rib 116 may be inserted into or in close contact with the rib groove 136 in the mounting member 130. The main body rib 116 may be in close contact with the rib groove 136 to stably hold the mounting member 130 in its normal position in the lower body 110 and to prevent the upper body 120 from shaking relative to the lower body 110.

[0175] Reference Figure 32 and Figure 33 The column 140 may extend upward from one side of the mounting member 130. The column 140 may surround a portion of the mounting space 135.

The first sensor 155 can be positioned facing the first chamber C1. The first sensor 155 can be positioned facing the insertion space 214. The second sensor 157 can face the mounting space 135. Because the first sensor 155 is tilted upwards, its sensitivity can be increased when it is used to detect information about the rod 400.

[0181] The inner wall 141 of the pillar 140 divides the internal space into mounting space 144 and mounting space 135. The inner wall 141 can cover one side of the mounting space 144. The inner wall 141 can cover the PCB assembly 150. The inner wall 141 can be connected to the pillar 140 via a threaded engagement between a screw and a screw in the mounting space 144.

The screw 138 may engage with the second threaded hole 1335 through the first threaded hole 1338 to attach the mounting member 130 to the lower body 110.

[0200] Reference Figure 38 and Figure 39 The cylinder 200 can be inserted into the mounting space 135. The mounting member 130 can surround and support the third portion 230 of the cylinder 200 inserted into the mounting space 135.

[0203] Therefore, it can prevent the accumulation of liquid generated in the second chamber C2 or liquid leaked from the second chamber C2 at the second sensor 157, and can prevent the second sensor 157 from malfunctioning.

[0204] Reference Figure 39 and Figure 40Air can be introduced into the aerosol generating device when the user inhales air while holding the stick in his / her mouth. External air can pass through the gap between the insertion opening wall 305 of the cap 300 and the stick 400 and can be introduced into the aerosol generating device.
