The lower end of the inner wall 212 of the first container 210 can press the second sealing portion 252 toward the frame 240.

[0128] Therefore, it is possible to prevent the liquid stored in the first chamber C1 from leaking into the gap between the inner wall 212 of the first container 210 and the frame 240.

[0129] Mounting member 130 may include a sensor receiving portion 137. The sensor receiving portion 137 may provide space formed at the lower portion of a sidewall of mounting member 130.

An extension 232 of the lower housing 230 may cover the upper portion of the sensor receiving portion 137.

[0130] A gap can be formed between the sensor housing 137 and the lower housing 230 for airflow. Air can pass through the gap between the sensor housing 137 and the lower housing 230 and can be introduced into the cylinder inlet 224. The second sensor 180 can sense the flow of air entering the cylinder inlet 224 through the gap between the sensor housing 137 and the lower housing 230.

[0131] Reference Figure 15 and Figure 16 The cylinder 200 may include a rod stop 217 that protrudes inwardly from the periphery of the insertion space 214 at a location adjacent to the opposite end or lower end of the insertion space 214. The rod stop 217 may protrude in a radially inward direction. The rod stop 217 may be formed on the outer wall 211 and / or inner wall 212 of the first container 210.

[0132] Multiple rod stops 217 can be provided. Three rod stops 217 can be provided. Multiple rod stops 217 can be arranged along the periphery of the insertion space 214. The rod stops 217 can be arranged in a circumferential direction. The rod stops 217 can be spaced apart from each other. The rod stops 217 can be formed in the shape of a rib or ring, which extends circumferentially along the periphery of the insertion space 214. A rod 400 can be positioned above the rod stops 217. The rod stops 217 can have a shape that gradually widens in the upward direction.

[0133] Therefore, when the rod 400 is inserted into the insertion space 214, the end of the rod 400 can contact the rod stop 217, which prevents the rod 400 from moving beyond the insertion space 214 into the second chamber C2.

[0134] In addition, the reduction in the amount of air flowing from the second chamber C2 to the insertion space 214 can be minimized.

[0135] Furthermore, the rod stop 217 can not prevent the aerosol generated in the second chamber C2 from extracting specific components from the medium in the rod 400.

[0136] Reference Figure 17 and Figure 18 The pivot or shaft 311 of the cover 310 may be positioned above the insertion space 214. The pivot or shaft 311 of the cover 310 may be positioned between the insertion space 214 and the insertion hole 304. The cover 310 may pivot toward the interior of the insertion space 214 to open the insertion space 214 and / or the insertion hole 304. The direction of pivoting of the cover 310 toward the interior of the insertion space 214 may be defined as a first direction.

[0137] When the cover 310 pivots in a first direction to open the insertion space 214, the cover 310 can be received in the cover recess 215. When the cover 310 opens the insertion space 214, the cover 310 can be received in the cover recess 215 and can overlap with the inner wall 212 of the first container 210 disposed below the cover recess 215. When the cover 310 opens the insertion space 214, the cover 310 can be configured to be parallel to the inner wall 212 of the first container 210 located below the cover recess 215.

[0138] The first guide 216 may be formed to slope downwards from the bottom of the cover recess 215 toward the insertion space 214. The first guide 216 may be sloped such that the insertion space 214 gradually narrows downwards. When the cover 310 opens the insertion space 214, the first guide 216 may be positioned adjacent to one end of the cover 310 at a location below the cover 310. When the cover 310 opens the insertion space 214, the first guide 216 may protrude further toward the insertion space 214 than the end of the cover 310.

[0139] The cover 310 can pivot outward toward the insertion space 214 to close the insertion space 214 and / or the insertion hole 304. The direction of pivoting of the cover 310 toward the insertion space 214 can be defined as a second direction. One end of the spring 312 can support the cover 310, and the other end of the spring 312 can support the cap 300. The spring 312 can provide a spring force to the cover 310 in the direction that the cover 310 closes the insertion space 214. The cover 310 can pivot in the second direction via the spring 312.

[0140] The second guide 306 may be angled such that the internal space gradually narrows towards its lower side. The second guide 306 may be positioned adjacent to the pivot radius of the cover 310. The second guide 306 may be positioned outside the pivot radius of the cover 310. The second guide 306 may extend angled along the pivot radius of the cover 310.

[0141] One end of the second guide 306 may be adjacent to the insertion hole 304. The end of the second guide 306 may be located outside the insertion hole 304. The end of the second guide 306 may be located below the insertion hole wall 305. The insertion hole wall 305 may protrude inwardly further than the end of the second guide 306. When the cover 310 pivots in the second direction to close the insertion space 214, the cover 310 may contact the insertion hole wall 305, thus restricting its movement.

[0142] The other end of the second guide 306 may be adjacent to the insertion space 214. The other end of the second guide 306 may be adjacent to the outer wall 211 of the first container 210 that forms the periphery of the insertion space 214. The other end of the second guide 306 may be positioned above the outer wall 211 of the first container 210 defining the insertion space 214. The second guide 306 may have a shape that extends in an inclined manner from one end to the other.

[0143] Reference Figures 19 to 22 The rod 400 can push the cover 310 in the inward direction of the insertion space 214 or in a first direction. When the rod 400 pushes the cover 310 and is inserted into the insertion space 214, the cover 310 can open the insertion space 214 and / or the insertion hole 304.

[0144] Reference Figure 19 and Figure 20 When the end of the rod 400 passes through the insertion hole 304, one end of the rod 400 can contact the insertion hole wall 305. When the end of the rod 400 contacts the insertion hole wall 305, the insertion hole wall 305 can guide the rod 400 into the correct position in the insertion hole 304. After passing through the insertion hole 304, the end of the rod 400 can push the cover 310, causing the cover 310 to pivot in a first direction.

[0145] Reference Figure 20 and Figure 21 When the rod 400 has fully passed through the insertion hole 304, the cover 310 can be received in the cover recess 215. The cover 310 can overlap with the inner wall 212 of the first container 210, thereby forming a sidewall of the insertion space 214 together with the inner wall 212 of the first container 210.

[0146] Reference Figure 21 and Figure 22 The rod 400 can slide along the surface of the cover 310 and can be inserted into the insertion space 214. The second guide 306 can be positioned pivotally opposite the cover 310 relative to the insertion hole 304. The second guide 306 can be positioned opposite the cover recess 215. When the rod 400 is inserted into the insertion space 214, the end of the rod 400 can contact the second guide 306. When the end of the rod 400 contacts the second guide 306, the second guide 306 can guide the rod 400 to the correct position in the insertion space 214.

[0147] The first guide 216 may be positioned opposite the second guide 306. The first guide 216 may be positioned below the second guide 306. The first guide 216 may be positioned below the cover recess 215. The first guide 216 may be positioned below the cover 310. The first guide 216 may extend circumferentially along the inner wall 212 of the first container 210. When the rod 400 is inserted into the insertion space 214, the end of the rod 400 may contact the first guide 216. After being guided to the correct position by contacting the second guide 306, the end of the rod 400 may contact the first guide 216. When the end of the rod 400 contacts the first guide 216, the first guide 216 can guide the rod 400 to the correct position in the insertion space 214.

[0148] The end of rod 400 inserted into insertion space 214 may contact rod stop 217. Rod stop 217, which contacts the end of rod 400, can prevent rod 400 from moving to the area below insertion space 214 or to the second chamber C2.

[0149] Therefore, when the user uses the rod 400 to push the cover 310, the rod 400 can be guided to the correct position so as to smoothly pass through the insertion hole 304 and push the cover 310.

[0150] Furthermore, when the rod 400 pushes the cover 310 and thus the cover 310 is positioned in the insertion space 214, the cover 310 is received in the cover recess 215, so the rod 400 can come into close contact with the wall defining the insertion space 214.

[0151] Furthermore, since the rod 400 is in close contact with the wall of the defined insertion space 214, unnecessary airflow between the insertion space 214 and the rod 400 can be prevented when the user inhales air through the rod 400, and the waste of suction force can be reduced, thereby preventing the deterioration of airflow efficiency.

[0152] Furthermore, even when the user uses the stick 400 to push the cover 310, the cover 310 applies an external force to the end of the stick 400 in the second direction, the stick 400 can be guided to be correctly inserted into the insertion space 214.

[0153] In addition, it can prevent rod 400 from moving into the interior of the second chamber C2.

[0154] Reference Figure 23 The upper body 120 can be connected to the upper portion of the lower body 110. The mounting member 130 can cover the upper portion of the lower body 110. The lower portion of the mounting member 130 can be surrounded by the upper portion of the side wall 111 of the lower body 110. The mounting member 130 can be connected to the upper portion of the lower body 110. The mounting member 130 can be connected to the lower body 110 in a snap-fit ​​manner. The mounting member 130 can engage with the lower body 110 so as not to detach from the lower body 110.

[0155] The second sensor 180 can be disposed on one side of the upper portion of the lower body 110. The sensor support portion 185 can have a shape extending upward from the upper portion of the lower body 110. The sensor support portion 185 can support the second sensor 180. The second sensor 180 can be coupled to the sensor support portion 185. The second sensor 180 can be coupled to the sensor support portion 185 for orientation in the lateral direction. The sensor receiving portion 137 of the mounting member 130 can receive and cover the second sensor 180 and the sensor support portion 185.

[0156] Reference Figures 24 to 26 A fastening hole 135 may be formed in the lower portion of the mounting member 130. The fastening hole 135 may be formed on the side of the lower portion of the mounting member 130. Multiple fastening holes 135 may be formed, and the multiple fastening holes 135 may be arranged along the periphery of the lower portion of the mounting member 130. A body latch 115 provided at the upper portion of the lower body 110 can be inserted into the fastening hole 135, thereby allowing the mounting member 130 and the lower body 110 to engage with each other (see...). Figure 28 and Figure 29 ).

[0157] A rib recess 136 may be formed in the outer surface 132 of the mounting member 130. The rib recess 136 may have a shape that is recessed inward from the outer surface 132 of the mounting member 130. The rib recess 136 may have a shape that extends along the periphery of the outer surface 132 of the mounting member 130. A body rib 116 extending along the inner periphery of the upper portion of the lower body 110 may be inserted into the rib recess 136, thereby allowing the mounting member 130 and the lower body 110 to engage with each other. The body rib 116 may be made of an elastic material. For example, the body rib 116 may be made of a material such as rubber or silicone. The body rib 116 may be in close contact with the rib recess 136. Therefore, the position of the mounting member 130 can be reliably fixed to the lower body 110, and the upper body 120 can be prevented from shaking relative to the lower body 110 (see...). Figure 28 and Figure 29 ).

[0158] A first fixing portion 138 may be formed at the lower portion of the mounting member 130. The first fixing portion 138 may be recessed upwards or protruded downwards from the lower portion of the mounting member 130. The first fixing portion 138 may be formed around the periphery of the lower portion of the mounting member 130. Multiple first fixing portions 138 may be formed, and multiple first fixing portions 138 may be arranged along the periphery of the lower portion of the mounting member 130. A second fixing portion 118 provided at the upper portion of the lower body 110 may be connected to the first fixing portion 138. Therefore, the position of the mounting member 130 can be reliably fixed to the lower body 110, and vibration of the upper body 120 relative to the lower body 110 can be prevented (see...). Figure 28 and Figure 29 ).

[0159] The upper body 120 may include an upwardly extending column 140. The column 140 may extend upwardly from one side of the mounting member 130. Side walls 141 and 142 of the column 140 may connect to side surfaces 131 and 132 of the mounting member 130. The column 140 may cover a portion of the space 134 provided by the mounting member 130. The inner side wall 141 of the column 140 may have an outwardly concave shape. The column 140 may face the side portion of the cylinder 200 (see...). Figure 6 The column 140 may cover one side portion of the cylinder 200. The column 140 may be open toward one side portion of the cylinder 200.

[0160] The column 140 may house the PCB assembly 150. The PCB assembly 150 may provide light to the cylinder 200 or sense information about the cylinder 200. For example, the information about the cylinder 200 may include 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 whether the rod 400 is inserted into the insertion space 214 of the cylinder 200; information about the type of rod 400 inserted into the insertion space 214 of the cylinder 200; information about the degree of use or availability of the rod 400 inserted into the insertion space 214 of the cylinder 200; information about whether the cylinder 200 with the rod 400 inserted into the insertion space 214 is connected to the body 100; or information about the type of cylinder 200 connected to the body 100. The information about the cylinder 200 is not limited to the information described above. The column 140 may house a light source 153 configured to emit light. The column 140 may accommodate a first sensor 154, which is configured to sense information about the cylinder 200.

[0161] The column 140 may have an installation space 144 therein. The installation space 144 may have a shape that extends vertically along the column 140. The inner sidewall 141 of the column 140 may surround the installation space 144. The installation space 144 may open toward the space 134 in the mounting member 130. The installation space 144 may open toward one side portion of the cylinder 200.

[0162] PCB assembly 150 can be mounted in mounting space 144. Board 160 can cover PCB assembly 150 and can be positioned in mounting space 144. Window 170 can cover PCB assembly 150 and mounting space 144. PCB assembly 150, board 160, and window 170 can be stacked sequentially. Mounting space 144 can be referred to as component receiving space 144.

[0163] PCB assembly 150 may include at least one of a printed circuit board (PCB) 151, a light source 153, or a first sensor 154. The light source 153 may be mounted on the PCB 151. At least one light source 153 may be provided. The first sensor 154 may be mounted on the PCB. The light source 153 and the first sensor 154 may be mounted at different locations on a single PCB. The first sensor 154 may be mounted in an area that avoids at least one light source 153.

[0164] The PCB assembly 150 may be disposed inside the post 140 facing the cylinder 200. The PCB assembly 150 may face the first container 210, which is provided with a first chamber C1 and an insertion space 214. The PCB assembly 150 may extend vertically along the post 140. A connector 152 for electrical connection may be formed at one end of the PCB assembly 150.

[0165] PCB 151 can extend vertically along post 140. PCB 151 can be a flexible printed circuit board (FPCB). Connector 152 can be formed at one end of PCB 151. Multiple light sources 153 can be arranged on PCB 151. First sensor 154 can be located at the center of PCB 151. First sensor 154 can be located between light sources 153, and at least one light source 153 can be disposed on each side of first sensor 154. Multiple light sources 153 can be arranged vertically along PCB 151. Multiple light sources 153 can be arranged in the longitudinal direction of post 140. First sensor 154 can be configured to face insertion space 214. Light sources 153 can be configured to face the outside of insertion space 214. Light sources 153 can emit light toward the outside of insertion space 214, such that light is provided to first chamber C1. Light source 153 can be LED.

[0166] Therefore, the light source 153 can provide uniform light to the first chamber C1.

[0167] In addition, it can prevent the path of light provided by the light source 153 from being blocked by the rod 400 inserted into the insertion space 214.

[0168] The first sensor 154 can extend vertically along the PCB 151. The first sensor 154 can extend along the first container 210 or the insertion space 214. The first sensor 154 can face the insertion space 214. The first sensor 154 can sense information about the cylinder 200. For example, the first sensor 154 can sense 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 whether the rod 400 is inserted into the insertion space 214 of the cylinder 200; information about the type of rod 400 inserted into the insertion space 214 of the cylinder 200; information about the degree of use or availability of the rod 400 inserted into the insertion space 214 of the cylinder 200; information about whether the cylinder 200 with the rod 400 inserted into the insertion space 214 is connected to the body 100; or information about the type of cylinder 200 connected to the body 100. The information about the cylinder 200 is not limited to the information described above.

[0169] The first sensor 154 can sense changes in the electromagnetic properties of the cylinder 200 to sense information about the cylinder 200. The first sensor 154 can sense changes in the electromagnetic properties caused by adjacent objects. For example, the first sensor 154 can be a capacitive sensor. For example, the first sensor 154 can be a magnetic proximity sensor. The type of the first sensor 154 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 volume of the liquid stored in the first chamber C1 changes, the electromagnetic properties sensed by the first sensor 154 can change, and the first sensor 154 can measure this change to sense information about the cylinder 200.

[0170] Window 170 can be attached to post 140. Window 170 can be formed of a transparent material. Window 170 allows light to pass through it. Window 170 can be attached to post 140 to cover PCB assembly 150 (see...). Figure 26 Window 170 may have a shape that extends vertically along column 140. Window 170 may be disposed between column 140 and cylinder 200. Window 170 may be disposed adjacent to the inner sidewall 141 of column 140. Window 170 may cover one side portion of cylinder 200. Window 170 may face the side portion of cylinder 200. Window 170 may be formed thin such that PCB assembly 150 is adjacent to cylinder 200.

[0171] A surface 171a of window 170 may contact a side portion of cylinder 200 to support cylinder 200 (see [link]). Figures 4 to 6 The opposing surface 171b of window 170 can be in close contact with PCB assembly 150 (see...). Figure 27 ). Surface 171a of window 170 may be referred to as the front surface of window 170. The opposite surface 171b of window 170 may be referred to as the rear surface of window 170.

[0172] The surface 171a of window 170 may have a shape corresponding to the shape of the outer wall 211 of the first container 210 forming the periphery of the insertion space 214. The insertion space 214 may be adjacent to the pillar 140 and the PCB assembly 150 (see [link]). Figure 15The insertion space 214 may be located between the first chamber C1 and the column 140. The outer wall 211 of the first container 210 surrounding the periphery of the insertion space 214 may have a circular shape extending along the periphery of the insertion space 214. The surface 171a of the window 170 may have a circular shape surrounding the outer side of the insertion space 214. The surface 171a of the window 170 may have a circular shape surrounding the outer wall 211 of the first container 210, which forms the periphery of the insertion space 214. The surface 171a of the window 170 may have a recessed shape in the direction opposite to that of the cylinder 200. The surface 171a of the window 170 may support one sidewall of the cylinder 200.

[0173] At least one recess 174 accommodating a light source 153 may be formed in the opposing surface 171b of the window 170. The recess 174 may be referred to as a light source recess 174 or a window recess 174. The light source recess 174 may be recessed from the opposing surface 171b of the window 170 toward the surface 171a. Each of the plurality of light source recesses 174 may accommodate and cover a corresponding light source among the plurality of light sources 153. Each of the plurality of light source recesses 174 may be formed at a position corresponding to the position of a corresponding light source among the plurality of light sources 153. The plurality of light source recesses 174 may be arranged vertically. A first sensor 154 may be located between the plurality of light source recesses 174, and at least one light source recess 174 may be disposed on each side of the first sensor 154.

[0174] The opposing surface 171b of window 170 may include a planar portion 172, which is formed to be flat. The planar portion 172 can be in close contact with PCB assembly 150. The planar portion 172 can be inserted into mounting space 144 in post 140 (see [link to mounting space]). Figure 24 The light source recess 174 can be formed by recessing the planar portion 172.

[0175] The PCB assembly 150 may have a plurality of through holes 151a formed therein. The through holes 151a may be formed on one side of the PCB 151. The through holes 151a may be formed in the upper portion of the PCB 151. The through holes 151a may be located above the light source 153 and / or the first sensor 154. The through holes 151a may be located on both sides of the PCB 151.

[0176] Window 170 may include multiple through protrusions 172a. Through protrusions 172a may protrude from the opposing surface 171b of window 170. Through protrusions 172a may be formed at positions corresponding to vias 151a. Through protrusions 172a may protrude toward vias 151a. Through protrusions 172a may pass through vias 151a. Multiple through protrusions 172a may be provided. Each of the multiple through protrusions 172a may pass through a corresponding via in the multiple vias 151a. Because through protrusions 172a pass through vias 151a, PCB assembly 150 and window 170 can be positioned correctly.

[0177] Window 170 may include latch protrusions 173. Latch protrusions 173 may be formed on opposing surfaces 171b of window 170. Latch protrusions 173 may project from each side of planar portion 172. Multiple latch protrusions 173 may be provided, and the multiple latch protrusions 173 may be arranged in a vertical direction. Each of the multiple latch protrusions 173 may have a shape that extends vertically to correspond to a side flange portion 1451.

[0178] The column 140 may include a flange 145. The flange 145 may be disposed within the inner wall 141 of the column 140. The flange 145 may project inwardly from the inner wall 141 of the column 140. The flange 145 may be integrally formed with the column 140. The flange 145 may project inwardly toward the column 140 to form an edge. The flange 145 may extend along the periphery of the component receiving space 144. The flange 145 may have an open center through which the component receiving space 144 and the cylinder receiving space 134 may be connected to each other.

[0179] The flange 145 may include at least one of a side flange portion 1451, a lower flange portion 1452, or an upper flange portion 1453. The flange 145 may be formed such that the side flange portions 1451, lower flange portions 1452, and upper flange portions 1453 are connected to each other. The side flange portions 1451 may have a shape that extends in the longitudinal direction of the post 140. The side flange portions 1451 may be arranged in pairs, and the pair of side flange portions 1451 may be spaced apart from each other and may be formed on both sides of the post 140. The lower flange portion 1452 and the upper flange portion 1453 may be disposed between the pair of side flange portions 1451 and may be connected to the side flange portions 1451. The side flange portions 1451, lower flange portions 1452, and upper flange portions 1453 may be connected to each other to form the outer periphery of the flange 145. The area surrounded by the side flange portion 1451, the lower flange portion 1452 and the upper flange portion 1453 can be open, so that the component receiving space 144 and the cylinder receiving space 134 can communicate with each other.

[0180] The opposing surface 171b of window 170 can be attached to flange 145. The edge of the opposing surface of window 170 can be attached to flange 145. The opposing surface 171b of window 170 can be attached to flange 145 using an adhesive member. For example, the adhesive member can be a piece of tape or glue. The adhesive member is not limited thereto. Latch protrusion 173 can engage with flange 145, thus window 170 can be coupled to flange 145. Latch protrusion 173 can engage with side flange portion 1451. Flange 145 can have a shape corresponding to the shape of the opposing surface 171b of window 170 adjacent to the edge of window 170. Lower flange portion 1452 and upper flange portion 1453 can have concave shapes.

[0181] Therefore, the PCB assembly 150 can be protected from external influences and the PCB assembly 150 can be prevented from becoming separated.

[0182] In addition, light emitted from PCB assembly 150 can be supplied to tube 200.

[0183] Furthermore, the window 170, cylinder 200, and PCB assembly 150 can be reliably connected or fixed to each other.

[0184] Board 160 may cover an area of ​​PCB assembly 150 that avoids at least one light source 153. Board 160 may be attached to PCB assembly 150 to cover first sensor 154. Board 160 may allow electromagnetic waves to pass through it. Board 160 allowing electromagnetic waves to pass through may not allow visible light to pass through it, or it may be translucent.

[0185] The printed circuit connected to the light source 153 can be printed on an area of ​​the PCB 151 adjacent to the light source 153. The board 160 can cover the printed circuit on the PCB 151 near the light source 153. The board 160 can have a shape that extends vertically along the first sensor 154 and extends further toward the printed circuit from its vertically extending portion.

[0186] Board 160 may expose the light source 153, rather than covering it. The light source 153 may be positioned on either side of the first sensor 154, with the first sensor 154 inserted between the light sources 153, and the light sources 153 may be arranged vertically. The portion of board 160 corresponding to the position of the light source 153 may be open. When board 160 is attached to PCB assembly 150, the light source 153 may be exposed through the open portion of board 160.

[0187] Therefore, the light emitted from the light source 153 can be unobstructed, and the first sensor 154 and / or the printed circuit printed on the PCB 151 can be kept out of the external environment and protected from external influences.

[0188] Furthermore, the first sensor 154 can sense changes in the electromagnetic properties of the surrounding environment while it is covered by the plate 160.

[0189] Reference Figure 27 PCB assembly 150 may be disposed inside post 140 and may extend along post 140. PCB 151 may extend along post 140. Connector 152 formed at one end of PCB assembly 150 may be exposed downward from upper body 120. Connector 152 may be exposed downward from post 140. Connector 152 may be exposed downward from mounting member 130. The lower end of post 140 may be open to form gap 146. Connector 152 may be exposed downward through gap 146. Gap 146 may communicate with mounting space 144 (see...). Figure 24 ).

[0190] Mounting member 130 may include a sensor receiving portion 137. The sensor receiving portion 137 may be formed in a sidewall of mounting member 130. The sensor receiving portion 137 may provide a space 137b formed in the sidewall of mounting member 130 to open downwards to receive a second sensor 180 inserted therein. The space 137b provided by the sensor receiving portion 137 may be referred to as sensor receiving space 137b. The inner surface of the sensor receiving portion 137 may form a portion of the inner surface 131 of mounting member 130. The outer surface of the sensor receiving portion 137 may form a portion of the outer surface 132 of mounting member 130. The sensor receiving portion 137 may be formed at a position opposite to the post 140 relative to the cylindrical receiving space 134. The post 140 may extend upwards from one side of mounting member 130, and the sensor receiving portion 137 may be formed on the opposite side of mounting member 130.

[0191] The inner surface 131 of the sensor receiving portion 137 may be open to form a sensing hole 137a. The sensing hole 137a may be formed between the sensor receiving space 137b and the cylinder receiving space 134 to interconnect the sensor receiving space 137b and the cylinder receiving space 134. The sensing hole 137a may be adjacent to the cylinder inlet 224 (see [link]). Figure 15 The sensing port 137a can face the cylinder inlet 224.

[0192] The sensing aperture 137a can be open in the lateral direction. The side portion of the second container 220 can be open to form a cylinder inlet 224, and the laterally open sensing aperture 137a can face the cylinder inlet 224 (see [reference]). Figure 15 ).

[0193] Reference Figure 28 and Figure 29The partition wall 112 of the lower body 110 can cover the upper side of the battery 190.

Among the plurality of uneven portions 2515, at least one uneven portion may be formed at a height corresponding to each of the first portion 2511 and the second portion 2512 of the first sealing portion 251. For example, one of the two first uneven portions 2515 may be formed at a height corresponding to the first portion 2511, and thus the other may be formed at a height corresponding to the second portion 2512.

[0252] The first sealing portion 251 can engage with hooks 2415. A plurality of hooks 2415 can be arranged along the periphery of the first frame portion 241 and can engage with the periphery of the first sealing portion 251.

The support portion 2428 may support the sealing member 250. The support portion 2428 may support the second sealing portion 252. The support portion 2428 may support the lower side of the body 2521 of the second sealing portion.

[0263] Reference Figure 39 The core retainer 2526 can be inserted into or in close contact with the core insertion recess 2426. The core retainer 2526 can press down on the end of the core 261 that is inserted into the core insertion recess 2426. Each of a pair of core retainers 2526 can press down on the corresponding end of the two ends of the core 261 that is inserted into the corresponding core insertion recess 2426. The core retainer 2526 can be in close contact with the sidewall 2421 of the core 261 and the second frame portion 242 where the core insertion recess 2426 is formed.

[0264] Therefore, core 261 can be stably connected or fixed, and the liquid supplied to core 261 can be prevented from leaking into the area around core 261.

[0265] Reference Figure 40 The connecting space 2417 interconnects the first chamber C1 and the second chamber C2. The connecting space 2417 may be formed between the first chamber C1 and the second chamber C2, or it may be formed in the portion of the first chamber C1 adjacent to the second chamber C2. The connecting space 2417 may be referred to as the chamber connecting space 2417.

[0266] An end of the core 261 may be disposed within the connecting space 2417. The end of the core 261 may pass through the gap between the core insertion recess 2426 and the core holder 2526 and may be exposed in the connecting space 2417. The connecting spaces 2417 may be provided in pairs. Each of the pair of connecting spaces 2417 may be positioned adjacent to a corresponding end of the two ends of the core 261. The pair of connecting spaces 2417 may be formed between the first sealing portion 251 and the second sealing portion 252. An inclined portion 2416 may be formed below the connecting space 2417. Each of the pair of inclined portions 2416 may be formed below a corresponding connecting space in the pair of connecting spaces 2417.

[0267] Reference Figure 41 and Figure 42 The sidewall 2421 of the second frame portion 242 may surround the side portion of the second chamber C2. The sidewall 2421 of the second frame portion 242 may be adjacent to the lower end of the inner wall 212 of the first container 210.

[0268] The lower support surface 2522 and the side support surface 2523 may surround the lower edge of the inner wall 212 of the first container 210 and be in close contact with the lower edge of the inner wall 212 of the first container 210. The lower support surface 2522 may support the lower end surface of the inner wall 212 of the first container 210. The lower support surface 2522 may extend along the periphery of the inner wall 212 of the first container 210.

[0269] The side support surface 2523 may extend along the periphery of the inner wall 212 of the first container 210. The side support surface 2523 may support a side surface adjacent to the lower end surface of the inner wall 212 of the first container 210.

[0270] The support portion 2428 can be disposed below the inner wall 212 of the first container 210. The support portion 2428 can be positioned along a line extending outward from the inner wall 212 of the first container 210.

[0271] The first container 210 can be connected to the second container 220. The outer wall 211 of the first container 210 can be connected to the periphery of the lower outer shell 230. The lower end of the outer wall 211 of the first container 210 can be recessed upward, so that the outer peripheral portion 2322 is inserted into the lower end. The outer wall 211 of the first container 210 can be attached to the outer peripheral portion 2322.

[0272] When the first container 210 is connected to the lower outer shell 230, the first sealing portion 251 can be in close contact with the first frame portion 241 and the outer wall 211 of the first container 210.

[0273] When the first container 210 is connected to the lower outer casing 230, the inner wall 212 of the first container 210 can press the second sealing portion 252 against the second frame portion 242. When the inner wall 212 of the first container 210 presses against the second sealing portion 252, the second sealing portion 252 can come into close contact with both the inner wall 212 of the first container 210 and the second frame portion 242. The second sealing portion 252 can transmit the force received from the inner wall 212 of the first container 210 to the first sealing portion 251 and the second frame portion 242.

[0274] Therefore, the number of parts connected using adhesive components can be reduced, and the number of parts used for connecting components can also be reduced. As a result, the structure of the components used in the connecting cylinder 200 can be simplified, and manufacturing efficiency can be improved.

[0275] Furthermore, the sealing member 250 can be stably connected or fixed without the use of a separate adhesive member, and can be in close contact with adjacent parts, thereby providing an airtight seal to the adjacent parts.

[0276] Reference Figure 43 Multiple first uneven portions 2515 may be formed on the outer peripheral surface of the first sealing portion 251. When the first container 210 is connected to the second container 220, the first uneven portions 2515 may be in close contact with the outer wall 211 of the first container 210.

[0277] At least one of the first uneven portions 2515 may be formed at a height corresponding to the first portion 2511 of the first sealing portion 251. The outer wall 211 of the first container 210 may be in close contact with the first uneven portion 2515 formed at a height corresponding to the first portion 2511.

[0278] Therefore, the first sealing portion 251 can receive the inward force of the outer wall 211 of the first container 210, and thus can make closer contact with the side portion of the side wall 2412 of the first frame portion 241.

[0279] At least one of the first uneven portions 2515 may be formed at a height corresponding to the second portion 2512 of the first sealing portion 251. The outer wall 211 of the first container 210 may be in close contact with the first uneven portion 2515 formed at a height corresponding to the second portion 2512.

[0280] Therefore, when the outer wall 211 of the first container 210 is connected to the lower outer shell 230, the second part 2512 of the first sealing part 251 can receive forces in the inward and downward directions, thereby pressing down on the upper part of the side wall 2412 of the first frame part 241.

[0281] In addition, the entire first sealing portion 251 can be in close contact with the outer wall 211 and the first frame portion 241 of the first container 210, thereby preventing liquid leakage.

The blocking wall 2317 can protrude upwards, and the cylinder inlet 224 can face in the lateral direction. The cylinder inlet 224 can face the surface of the blocking wall 2317. The cylinder inlet 224 can face the sensing hole 137a and the second sensor 180.

[0298] When a user inhales air through rod 400, outside air can be introduced into the aerosol generating device through cap inlet 304a. The air introduced into cap inlet 304a can sequentially pass through second channel P2 and first channel P1, and then through cylinder inlet 224 into cylinder 200. Second sensor 180 can sense the airflow through first channel P1. Second sensor 180 can sense the airflow through cylinder inlet 224.

[0299] Air that has passed through cylinder inlet 224 can pass through connecting channel 2314 and then through chamber inlet 2424 to be introduced into the second chamber C2. Air flowing through connecting channel 2314 can flow along circular surface 2418 toward chamber inlet 2424. Air introduced into the second chamber C2 can be supplied together with aerosol generated in the second chamber C2 to rod 400 inserted into insertion space 214.

[0300] Therefore, it is possible to prevent the liquid collected in the second chamber C2 from leaking out of the cylinder 200 through the cylinder inlet 224.

[0301] In addition, it can prevent aerosols generated in the cylinder 200 or liquids in the cylinder 200 from contacting the sensor 180, thereby preventing sensor 180 from malfunctioning.

[0302] In addition, it can improve the airflow efficiency outside the cylinder 200 and improve the sensing performance of the sensor 180.

[0303] In addition, it can reduce airflow loss in cylinder 200.

[0304] Reference Figure 46The rod 400 may include a medium portion 410. The rod 400 may include a cooling portion 420. The rod 400 may include a filter portion 430. The cooling portion 420 may be disposed between the medium portion 410 and the filter portion 430. The rod 400 may include a package 440. The package 440 may enclose the medium portion 410. The package 440 may enclose the cooling portion 420. The package 440 may enclose the filter portion 430. The rod 400 may have a cylindrical shape.

[0305] The medium portion 410 may include a medium 411. The medium portion 410 may include a first medium cover 413. The medium portion 410 may include a second medium cover 415. The medium 411 may be disposed between the first medium cover 413 and the second medium cover 415. The first medium cover 413 may be disposed at one end of the rod 400. The medium portion 410 may have a length of 24 mm.

[0306] Medium 411 may contain a multi-component substance. The substance contained in the medium may be a multi-component flavoring substance. Medium 411 may consist of multiple particles. Each of the multiple particles may have a size from 0.4 mm to 1.12 mm. These particles may occupy approximately 70% of the volume of medium 411. The length L2 of medium 411 may be 10 mm. A first medium cover 413 may be made of acetate material. A second medium cover 415 may be made of acetate material. The first medium cover 413 may be made of paper material. The second medium cover 415 may be made of paper material. At least one of the first medium cover 413 or the second medium cover 415 may be made of paper material and may be rolled up to wrinkle, and multiple gaps may be formed between these wrinkles to allow air to flow through these gaps. Each of the gaps may be smaller than each of the particles in medium 411. The length L1 of the first medium cover 413 may be shorter than the length L2 of medium 411. The length L3 of the second medium cover 415 may be shorter than the length L2 of medium 411. The length L1 of the first medium cover 413 can be 7mm. The length L2 of the second medium cover 415 can be 7mm.

[0307] Therefore, it is possible to prevent each particle of medium 411 from separating from medium portion 410 and rod 400.

[0308] The cooling section 420 may have a cylindrical shape. The cooling section 420 may have a hollow shape. The cooling section 420 may be disposed between the medium section 410 and the filter section 430. The cooling section 420 may be disposed between the second medium cover 415 and the filter section 430. The cooling section 420 may be formed in the shape of a tube surrounding the cooling path 424 formed therein. The cooling section 420 may be thicker than the packaging 440. The cooling section 420 may be made of a paper material thicker than the paper material of the packaging 440. The length L4 of the cooling section 420 may be equal to or approximately equal to the length L2 of the medium 411. The length L4 of each of the cooling section 420 and the cooling path 424 may be 10 mm. When the rod 400 is inserted into the aerosol generating device (see...) Figure 3 At least a portion of the cooling section 420 may be exposed to the outside of the aerosol generating device.

[0309] Therefore, the cooling section 420 can support the media section 410 and the filter section 430, and can ensure the rigidity of the rod 400. Furthermore, the cooling section 420 can support the package 440 between the media section 410 and the filter section 430, and can provide a portion for the package 440 to adhere to. Additionally, heated air and aerosol can be cooled as they pass through the cooling path 424 in the cooling section 420.

[0310] The filter section 430 may consist of a filter made of acetate material. The filter section 430 may be located at the other end of the rod 400. When the rod 400 is inserted into the aerosol generating device (see...), Figure 3 The filter section 430 can be exposed to the outside of the aerosol generating device. The user can inhale air while holding the filter section 430 in their mouth. The length L5 of the filter section 430 can be 14 mm.

[0311] The packaging 440 may wrap around or surround the medium portion 410, the cooling portion 420, and the filter portion 430. The packaging 440 may form the appearance of the rod 400. The packaging 440 may be made of paper material. An adhesive portion 441 may be formed along one edge of the packaging 440. The packaging 440 may surround the medium portion 410, the cooling portion 420, and the filter portion 430, and the adhesive portions 441 formed along one edge and the other edge of the packaging 440 may be adhered to each other. The packaging 440 may surround the medium portion 410, the cooling portion 420, and the filter portion 430, but may not cover one end or the other end of the rod 400.

[0312] Therefore, the packaging 440 can secure the media section 410, the cooling section 420, and the filter section 430, and can prevent these components from separating from the rod 400.

[0313] The first film 443 may be disposed at a position corresponding to the first medium cover 413. The first film 443 may be disposed between the package 440 and the first medium cover 413, or it may be disposed on the outside of the package 440. The first film 443 may surround the first medium cover 413. The first film 443 may be made of a metallic material. The first film 443 may be made of aluminum. The first film 443 may be in close contact with the package 440, or it may be coated thereon.

[0314] The second film 445 may be disposed at a position corresponding to the second medium cover 415. The second film 445 may be disposed between the package 440 and the second medium cover 415, or it may be disposed on the outside of the package 440.

The second inclined wall 2423 can be formed at a position corresponding to the first inclined wall 2313. The support rod 2316 can support the second inclined wall 2423.

[0323] Therefore, when the frame 240' is inserted into the receiving space 2310, the second inclined wall 2423 can slide along the support rod 2316, thereby guiding its positioning.

[0324] The latch hook 2329 may be formed to protrude upward from the bottom portion 2321 of the extension 232'. The latch hook 2329 may extend upward from the bottom portion 2321 and may be bent toward the insertion space 2310 to form a hook shape.

The sealing links 2531 can be arranged radially around the second sealing portion body 2521 toward the first sealing portion 251. The sealing links 2531 can be spaced apart from each other, and gaps can be formed between the sealing links 2531. Sealing hooks 2415 can be provided between the sealing links 2531. For example, four sealing links 2531 can be provided, and three sealing hooks 2415 can be provided such that one of the sealing hooks 2415 is located between a corresponding pair of adjacent sealing links 2531 among the four sealing links.

[0330] At least one pair of sealing links 2531 may be arranged parallel to each other.

[0333] A mounting groove 254 may be formed between the mounting portion 255 and the first portion 2511 of the first sealing portion 251. The mounting groove 254 may be open in the downward direction of the sealing member 250'. The second portion 2512 of the first sealing portion 251 may cover the upper side of the mounting groove 254.

[0334] The frame edge 2412 can be inserted into the mounting groove 254 to be fitted into the first sealing portion 251. The frame edge 2412 can be force-fitted into the mounting groove 254. The first sealing portion 251 can cover the frame edge 2412.

[0335] Therefore, the sealing member 250' can be securely fixed to the frame 240', and thus can be prevented from separating from the frame.

[0336] Reference Figure 54 and Figure 55 The inner wall 212 of the first container 210 can come into close contact with the second sealing portion 252 while pressing it downwards. When the inner wall 212 of the first container 210 presses down on the second sealing portion 252, a deformation force can be applied to the second sealing portion 252 in the radial direction. The deformation force applied to the second sealing portion 252 can be transmitted to the sealing link 2531. The sealing link 2531 can be arranged radially around the second sealing portion 252. The sealing hook 2415 can hold the first sealing portion 251 in a position near the sealing link 2531. The sealing hook 2415 can support the inner circumferential surface of the first sealing portion 251.

[0337] Therefore, when the components of the cylinder 200' are connected, deformation of the sealing member 250' or movement of the sealing member 250' from its correct position can be prevented.

[0338] Reference Figure 55 and Figure 56 The chamber inlet 2424 can open on one side of the second chamber C2 in a direction intersecting the longitudinal direction of the insertion space 214.

[0344] The sidewall 2311 of the receiving portion 231' can support the sidewall 2421 of the second frame 242'. The bottom 2312 of the receiving portion 231' can support the bottom 2422 of the second frame 242'.

[0345] The outer wall 211 of the first container 210 can be connected to the outer periphery 2322 of the lower outer shell 230. The inner wall 212 of the first container 210 can press the second frame 242 downward toward the lower outer shell 230. The lower outer shell 230 can support the second frame 242. A portion of the bottom portion 2411 of the first frame 241 can be supported by the bottom portion 2321 of the extension portion 232'. The extension portion 232' can support the bottom portion 2411 of the first frame 241 at a position between the latch hook 2329 and the inner wall 212 of the first container 210.

[0346] The latch hook 2329 can be inserted into the latch recess 2419 and thus can be engaged in the first frame 241. The latch hook 2329 can protrude upward from the bottom portion 2321 of the extension 232'. The latch hook 2329 can be positioned adjacent to the edge of the extension 232'. The latch hook 2329 can have a hook shape that protrudes upward from the bottom portion 2321 of the extension 232' and curves along a predetermined direction. The first frame 241 and the latch hook 2329 can receive supporting forces from each other in the vertical direction.

[0347] When the inner wall 212 of the first container 210 presses down on the second frame 242 toward the lower outer shell 230, the first frame 241 connected to the second frame 242 can receive a deformation force, causing the portion of it with the latch recess 2419 to be oriented upward relative to the extension 232' supporting the first frame 241. The first frame 241 can press the latch hook 2329 upward. The latch hook 2329 can support the first frame 241. The latch hook 2329 can support the first frame 241 in a downward direction.

[0348] Therefore, when assembling the cylinder 200', shape deformation of the frame 240 can be prevented, and the structural stability of the cylinder 200' can be improved. Furthermore, the number of parts connected using adhesive components can be minimized, thereby improving the ease of assembly of the cylinder 200'.

[0349] The inner wall 212 and outer wall 211 of the first container 210 surrounding the insertion space 214 may define a tube 212a. The first container 210 may be provided with the tube 212a.

The height difference W0 between the center of the chamber inlet 2424 and the center of the core 261 may be 1 mm or less. The height difference W0 between the center of the chamber inlet 2424 and the center of the core 261 may be 0.5 mm.

[0354] The chamber inlet 2424 can be located above the bottom of the second chamber C2. The core 261 can be located above the bottom of the second chamber C2. The height H from the bottom of the second chamber C2 to the lower end of the chamber inlet 2424 can be approximately equal to the height H from the bottom of the second chamber C2 to the lower end of the core 261. The height from the bottom of the second chamber C2 to the center of the core 261 can 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 upper end of the core 261 can be greater than the height from the bottom of the second chamber C2 to the upper end of the chamber inlet 2424. The chamber inlet 2424 can be set within the diameter W1 of the core 261.

[0355] The width W2 of the chamber inlet 2424 can be smaller than the diameter W1 of the core 261. The width of the chamber inlet 2424 can gradually increase toward the second chamber C2 or the core 261. The distance between the core 261 and the chamber inlet 2424 can be approximately equal to or approximately equal to the width W2 of the chamber inlet 2424.

[0356] The centerline 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 core 261 can be disposed between the centerline L and the chamber inlet 2424. The chamber inlet 2424 and the first flow guide 2318 can be positioned relative to each other with respect to the centerline L. The core 261 and the first flow guide 2318 can be positioned relative to each other with respect to the centerline L, but they do not need to overlap with the centerline L.

[0357] Core 261 may be adjacent to chamber inlet 2424. Core 261 may be positioned closer to chamber inlet 2424 than to the first flow guide 2318. In a cross-sectional view, core 261 may be positioned closer to the inner wall 212 of the first container 210 surrounding insertion space 214 than to the outer wall 211 of the first container 210 surrounding insertion space 214.

[0358] When a user inhales air through rod 400, air can be introduced into the second chamber C2 from chamber inlet 2424. Liquid can be supplied from the first chamber C1 to the core 261 and can be absorbed by the core 261. When heater 262 heats the core 261, which contains absorbed liquid, an aerosol can be generated. Air introduced into the second chamber C2 from chamber inlet 2424 can diffuse into the area surrounding the core 261 and can come into contact with or pass through the core 261.

[0359] After contacting or passing through core 261, aerosol-containing air can flow above and below core 261. Air flowing above core 261 can be introduced into insertion space 214. Air flowing below core 261 can move toward first flow guide 2318. A portion of the air moving toward first flow guide 2318 can be directly introduced into insertion space 214, and the remainder of the air can contact first flow guide 2318. First flow guide 2318 can guide the air in contact with it into insertion space 214.

[0360] Therefore, air can move uniformly from the chamber inlet 2424 to the core 261. Furthermore, since the air flowing from the chamber inlet 2424 towards the second chamber C2 passes through the core 261, the amount of aerosol contained in the air can be increased. Additionally, as the air introduced into the second chamber C2 from the chamber inlet 2424 moves towards the insertion space 214, the first flow guide 2318 can prevent air from remaining in the second chamber C2 or prevent the generation of eddies. Furthermore, the first flow guide 2318 can guide the air in contact with it to the insertion space 214.

[0361] The inner peripheral surface of the lower portion of the outer wall 211 surrounding the insertion space 214 of the first container 210 may include an inclined outer wall surface 218, which gradually widens toward its upper side in a radially outward direction. The inclined outer wall surface 218 may be inclined outward to gradually widen from the second chamber C2 toward the insertion space 214. The inclined outer wall surface 218 may be located above the first flow guide 2318.

[0362] Therefore, the air and aerosol introduced from the second chamber C2 into the insertion space 214 can be uniformly diffused to the lower surface of the rod 400 inserted into the insertion space 214.

An upper window frame portion 163 may be formed at the upper portion of the window frame 160'. Both ends of the upper window frame portion 163 may be connected to the upper ends of the opposite side window frame portion 161.

[0372] Reference Figure 60 and Figure 61 The PCB assembly 150' can be connected to the rear surface 172 of the window 170'. A first retaining arm 151b can project forward from the rear surface of the PCB 151. The first retaining arm 151b can be located on the upper side of the PCB 151. The first retaining arm 151b can be positioned adjacent to the third sensor 155.

[0374] Reference Figures 62 to 64 The latching protrusion 173 can be spaced rearward from the side window edge portion 1701 to form a gap. The latching protrusion 173 can be inserted into the gap 1454 in the rear side of the side flange portion 1451 formed in the post 140'. The latching protrusion 173 can be engaged in the side flange portion 1451. The side flange portion 1451 can be inserted into the gap between the latching protrusion 173 and the side window edge portion 1701. The latching protrusion 173 can be snap-fitted to the side flange portion 1451 and the gap 1454. The latching protrusion 173 can prevent the window 170' from separating from the post 140'.

[0375] The side window edge portion 1701 may cover the side flange portion 1451. The lower window edge portion 1702 may cover the lower flange portion 1452. The upper window edge portion 1703 may cover the upper flange portion 1453.

When the window 170' is attached to the post 140', the first retaining arm 151b and the second retaining arm 151c may be held in place by the rear surface of the window 170', thus the PCB assembly 150' may be secured to the window 170' in the correct position. One surface 171a or the front surface 171a of the window 170' may face the cylindrical receiving space 134. The opposite surface 171b or the rear surface 172 of the window 170' may face the interior of the post 140'.

[0376] Therefore, window 170' can be connected to post 140' via a snap-fit ​​connection so as not to separate from post 140'. Furthermore, the process of assembling window 170' to post 140' can be simplified. Additionally, window 170' can be stably fixed to post 140'.

The rear surface of the sidewall 1372 of the sensor cover 137' can be adhered to the front surface of the sensing frame 183 using an adhesive member.

[0392] Therefore, the sensor cover 137' can be easily attached and secured to the mounting piece 130', and can protect the second sensor 180.

[0393] Reference Figures 70 to 72 The lower outer casing 230' can be inserted into the cylindrical receiving space 134.

One side of the mounting member 130' or the sensor cover 137' can support the first inclined wall 2313.

[0396] The first inclined wall 2313 and side wall 1372 of the sensor cover 137' may be spaced apart from each other. A second flow guide 1373 may protrude from the sensor cover 137' toward the cylinder 200' and may be in close contact with the cylinder 200'. The second flow guide 1373 may contact the first inclined wall 2313. Because the second flow guide 1373 contacts the first inclined wall 2313, the first inclined wall 2313 may be spaced apart from the recessed cover surface 1374 and the sensing hole 137a. The second flow guide 1373 may be referred to as spacer 1373.

[0397] The cylinder inlet 224 can be disposed inside the second flow guide 1373. The cylinder inlet 224 can face the sensing aperture 137a. First side channel portion P12 (see...)

Each guide protrusion 131b may have a shape that gradually narrows upwards. The guide protrusion 131b may contact or connect to the bottom 132 of the mounting member 130'.

[0399] The guide recess 221b can be formed such that a portion of the sidewall 2311 of the receiving portion 231' is recessed. The guide recess 221b can have a shape that gradually narrows towards its upper side. The guide recess 221b can be recessed in a shape corresponding to the guide protrusion 131b. The lower end of the guide recess 221b can be open downwards. The guide recess 221b can be formed below the recessed portion 221a. The guide recesses 221b can be provided in pairs, and the pair of guide recesses 221b can be formed respectively in two opposing sidewalls 2311 of the receiving portion 231'. Each of the pair of guide recesses 221b can be disposed below a corresponding recessed portion in the pair of recessed portions 221a. The pair of guide recesses 221b can be disposed adjacent to the recessed portion 221a.

[0400] The protruding portion 131a can be inserted into the recessed portion 221a. The protruding portion 131a can be detachably engaged with the recessed portion 221a in a snap-fit ​​manner. The guide protrusion 131b can be inserted into the guide recess 221b. The guide protrusion 131b and the guide recess 221b may not engage with each other.

[0401] When the cylinder 200' is inserted into the space 134 in the mounting member 130', the first inclined wall 2313 can slide along the side wall 1372 of the sensor cover 137' or the second flow guide 1373. When the lower housing 230' is inserted into the cylinder receiving space 134, the guide recess 221b can slide along the guide protrusion 131b while contacting it. The front surface 171a of the pillar 140' or window 170' can support one surface of the cylinder 200'. When the cylinder 200' is inserted into the space 134 in the mounting member 130', the surface of the cylinder 200' can slide along the front surface 171a of the window 170'.

[0402] Therefore, the protruding portion 131a and the recessed portion 221a can be easily guided to their engagement positions. Furthermore, the lower housing 230' can be easily inserted into and engaged with the space 134 in the mounting member 130'.

[0403] refer to Figure 73 and Figure 74 The first channel P1 may include a first upper channel portion P11 and a first side channel portion P12. The first upper channel portion P11 may be formed between the upper wall 1371 of the sensor cover 137' and the extension portion 232'. The first upper channel portion P11 may be formed between the upper wall 1371 of the sensor cover 137' and the channel forming portion 2323. The first upper channel portion P11 may be formed between the second channel P2 and the first side channel portion P12. The first side channel portion P12 may be perpendicular to the second channel P2. The first side channel portion P12 may be surrounded by the second flow guide 1373 (see reference). Figure 66 ).

[0404] The first side channel portion P12 can be formed between the sidewall 1372 of the sensor cover 137' and the first inclined portion 2313. The first side channel portion P12 can also be formed between the recessed cover surface 1374 and the first inclined portion 2313. The first side channel portion P12 can interconnect the first upper channel portion P11 and the cylinder inlet 224. The first side channel portion P12 can also interconnect the first upper channel portion P11 and the sensing hole 137a. The first side channel portion P12 can also interconnect the sensing hole 137a and the cylinder inlet 224. The sensing hole 137a and the cylinder inlet 224 can face each other, with the first side channel portion P12 inserted between them. The first side channel portion P12 can be formed to slope downwards from the first upper channel portion P11.

[0405] When the user inhales air, the air can be introduced into the second channel P2 through the cap inlet 304a. The air passing through the second channel P2 can flow to the first upper channel portion P11 and the first side channel portion P12. Air can flow obliquely from the first upper channel portion P11 to the first side channel portion P12. The second flow guide 1373 (see...) Figure 66 The air flowing from the first upper channel portion P11 to the first side channel portion P12 can be guided to the sensing hole 137a and the cylinder inlet 224.

[0406] Therefore, air can be prevented from flowing outside the sensing hole 137a and the cylinder inlet 224 or from leaking outside the sensing hole 137a and the cylinder inlet 224. Furthermore, airflow efficiency can be improved. Additionally, the accuracy of the second sensor 180 can be improved.

[0407] Reference Figure 75 and Figure 76 A shaft 311 may be formed at one end of the cover 310. The shaft 311 may extend in a direction intersecting the cover 310. The cover 310 may pivot about the shaft 311.

[0408] Surface 313 of cap 310 can contact rod 400 (see...) Figure 80 Surface 313 of cover 310 may be referred to as front cover surface 313 or contact surface 313. Another surface 314 of cover 310 may be formed opposite to surface 313 of cover 310. Another surface 314 of cover 310 may be referred to as rear cover surface 314 or support surface 314. Cover support rod 317 may protrude from rear cover surface 314 of cover 310. Cover support rod 317 may extend in the longitudinal direction of shaft 311.

[0409] The cover edge 315 may extend in a circular shape along the edge of the cover 310. The cover edge 315 may be formed between the end of the front cover surface 313 and the edge of the rear cover surface 314. At least a portion of the cover edge 315 may have an upper insertion hole 304 (see reference). Figure 78 ) and lower insertion hole 3040 (reference) Figure 78 The corresponding shape. At least a portion of the edge 315 of the cover may have an arc shape or an arch shape.

[0410] A toe portion 315a may be formed at the end of the cover 310 or at the end of the cover edge 315. The toe portion 315a may be positioned relative to the cover 310 opposite to the shaft 311. The toe portion 315a may be formed to protrude outward from the front cover surface 313 to the rear cover surface 314. The toe portion 315a may have one side corresponding to the upper insertion hole 304 (see...). Figure 78 ) and one side of the lower insertion hole 3040 (reference) Figure 78 The toe portion 315a may have a shape corresponding to the outer peripheral surface of the upper end of the insertion space 214 (see [reference]). Figure 79 ).

[0411] The stick grip 316 can be connected to the pivot of the cover 310 and can pivot together with the cover 310. The stick grip 316 can be formed such that a portion of the shaft 311 is recessed. The stick grip 316 can form a side surface of the shaft 311. The stick grip 316 can be connected to the front cover surface 313. The stick grip 316 can protrude further than the front cover surface 313. The stick grip 316 can have a shape corresponding to one side of the outer peripheral surface of the stick 400 (see...). Figure 3 The bar gripper 316 can be formed such that a portion of the shaft 311 is concave into a circular shape. The bar gripper 316 can have one side that interacts with the outer peripheral surface of the insertion space 214 (see...). Figure 2 ) or one side of the inner circumferential surface of the inner wall 212 of cylinder 200 or 200' (see Figure 2 The corresponding shape.

[0412] The gripping recess 316a can be formed such that a portion of the shaft 311 is recessed. A bar gripping portion 316 can surround a portion of the gripping recess 316a. The gripping recess 316a can be formed in the portion where the shaft 311 connects to the front cover surface 313. The gripping recess 316a can be formed such that a portion of the shaft 311 is recessed from the front surface of the cover 310 into the shaft 311. A portion of the gripping recess 316a can be concavely recessed into a circle to form a curved surface.

[0413] A spring support surface 312a may be formed in a portion of the rear cover surface 314. The spring support surface 312a may be formed such that a portion of the rear cover surface 314 is recessed. The spring support surface 312a may extend in a direction intersecting the longitudinal direction of the shaft 311. Spring 312 (see...) Figure 12It can be wound around shaft 311. One side of spring 312 (see...) Figure 12 It can support the spring support surface 312a.

[0414] Reference Figure 77 The cover 310 may have a shape that is bent to bulge in a predetermined direction. The front cover surface 313 may bulge in a predetermined direction. The front cover surface 313 may be formed in an arc shape or an arch shape. The front cover surface 313 may bulge in a direction intersecting the longitudinal direction of the shaft 311.

[0415] The front cover surface 313 may include a protruding portion 313a and a boundary portion 313b. The protruding portion 313a may be an arched raised portion of the front cover surface 313, and the boundary portion 313b may be the remaining portion of the front cover surface 313 other than the protruding portion 313a. The front cover surface 313 may be formed as a continuous surface and may be circular from the protruding portion 313a to the boundary portion 313b.

[0416] The protruding portion 313a may protrude further than the boundary portion 313b in a predetermined direction. The protruding portion 313a may be formed between a pair of boundary portions 313b. The protruding portion 313a may be spaced apart from the bar gripping portion 316 and the gripping recess 316a. The protruding portion 313a may protrude in a direction intersecting the longitudinal direction of the shaft 311.

[0417] Boundary portions 313b may be located on two opposite sides of the protrusion 313a. Either of the boundary portions 313b may be adjacent to the shaft 311. Either of the boundary portions 313b may be closer to the shaft 311 than the protrusion 313a. Either of the boundary portions 313b may be connected to the rod gripping portion 316 and the gripping recess 316a. The other of the boundary portions 313b may be adjacent to the toe cap 315a.

[0418] The reference line Ls can be defined as an imaginary line connecting the end of the protrusion 313a and the end of the bar gripper 316. The boundary portion 313b can be spaced apart from the reference line Ls.

[0419] One outer peripheral surface of the rod 400 can be in close contact with the reference line Ls to be parallel to the reference line. The outer peripheral surface of one side of the rod 400 can pass through the gripping recess 316a. When the rod 400 is in close contact with the reference line Ls, the outer peripheral surface of one side of the rod 400 can contact the front cover surface 313 and the shaft 311. When the rod 400 is in close contact with the reference line Ls, the rod 400 can contact and be supported by the protrusion 313a and the rod gripping portion 316. When the rod 400 is in close contact with the reference line Ls, the rod 400 can be spaced apart from the boundary portion 313b. When the rod 400 is in close contact with the reference line Ls, the rod gripping portion 316 can surround and support the outer peripheral surface of one side of the rod 400.

[0420] Reference Figure 78 The lower insertion hole 3040 can be located below the insertion hole 304 in the cap 300. The insertion hole 304 can be referred to as the upper insertion hole 304. The upper insertion hole 304 can be formed in the upper head 340. The lower insertion hole 3040 can be formed in the lower head 330. The lower insertion hole 3040 can communicate with the upper insertion hole 304. The lower insertion hole 3040 can be located between the upper insertion hole 304 and the insertion space 214 (see...). Figure 79 ).

[0421] The outer peripheral insertion surface 306b may surround the outer periphery of the lower insertion hole 3040. The lower insertion hole 3040 may open upwards and downwards. The outer peripheral insertion surface 306b may have an arched shape. The outer peripheral insertion surface 306b may have a shape corresponding to the cover edge 315 (see...). Figure 75 The cover 310 and the shaft 311 can be located on one side of the lower insertion hole 3040.

[0422] The second rod guide 306 can protrude from the outer peripheral insertion surface 306b toward the lower insertion hole 3040. The second rod guide 306 can be configured relative to the lower insertion hole 3040 to be opposite to the shaft 311 of the cover 310. The second rod guide 306 can be tilted so that it gradually moves closer to the shaft 311 from its upper side to its lower side. The second rod guide 306 can protrude toward the shaft 311. When the rod 400 passes through the upper insertion hole 304 and the lower insertion hole 3040, the rod 400 can slide along the second rod guide 306 while contacting the second rod guide 306.

[0423] A rod support protrusion 306a may be formed at the lower end of the second rod guide 306. The rod support protrusion 306a may be the highest part of the second rod guide 306. The rod support protrusion 306a may have a shape extending from an arcuate shape to a circular shape. The rod support protrusion 306a may extend in a shape corresponding to one side of the outer peripheral surface of the insertion hole 304. The rod support protrusion 306a may extend in a shape corresponding to one side of the outer peripheral surface of the rod 400 (see...). Figure 80).

[0424] When the rod 400 is inserted into the insertion hole 304 and the insertion space 214, the rod support protrusion 306a can surround and support the outer peripheral surface of one side of the rod 400 (see...). Figure 80 When the rod is 400 (see...) Figure 80 When the rod 400 is inserted through the upper insertion hole 304 and the lower insertion hole 3040 is fixed, the rod 400 can be spaced apart from the outer peripheral insertion surface 306b.

[0425] Reference Figure 79 and Figure 80 The cover 310 can pivot about axis 311 to open and close the insertion hole 304 and the insertion space 214. The cover 310 can pivot in a first direction to open the insertion hole 304 and the insertion space 214. When the cover 310 opens the insertion hole 304, the cover 310 can be inserted into the cover recess 215. The cover 310 can pivot in a second direction to close the insertion hole 304 and the insertion space 214. When the cover 310 closes the insertion hole 304, the cover 310 can disengage from the cover recess 215. The cover 310 can receive a spring force in the second direction from an elastic member that provides elasticity. The elastic member can be a spring 312.

[0426] The rod 400 can pass through the upper insertion hole 304 and the lower insertion hole 3040, and can then be inserted into the insertion space 214. When the lower end of the rod 400 pushes the cover 310 to move through the insertion hole 304 into the insertion space 214, the cover 310 can pivot in a first direction. When the rod 400 separates from the insertion space 214 and the insertion hole 304, the cover 310 can pivot in a second direction. When the cover 310 pivots in the first direction, the shaft 311 and the rod gripping part 316 can also pivot in the same direction.

[0427] The rod support protrusion 306a can be configured to face the cover 310. The rod support protrusion 306a can protrude toward the cover 310. The rod support protrusion 306a can overlap the insertion space 214 in the vertical direction. The cover 310 can pivot toward the rod support protrusion 306a to close the opening in the insertion space 214. When the rod 400 is inserted into the insertion space 214, the cover 310 can press the rod 400 toward the rod support protrusion 306a. The opposite side of the rod 400 can be supported by the cover 310 and the rod support protrusion 306a.

[0428] When the cover 310 pivots in a first direction to open the opening in the insertion space 214, the protrusion 313a of the cover 310 may protrude toward the rod support protrusion 306a. When the cover 310 opens the opening in the insertion space 214, the protrusion 313a may overlap the insertion space 214 in the vertical direction. When the rod 400 pushes the cover 310 to open the insertion space 214, the end of the rod 400 may slide along the protrusion 313a from the boundary portion 313b of the cover 310. When the rod 400 is inserted into the insertion space 214, the rod 400 may contact the protrusion 313a but may not contact the boundary portion 313b. The opposite sides of the rod 400 may be supported by the protrusion 313a and the rod support protrusion 306a.

[0429] The rod grip 316 can be connected to a pivot or shaft 311 of the cover 310 to pivot together with the cover 310. When the cover 310 closes the insertion space 214, the rod grip 316 can face upwards. When the cover 310 closes the insertion space 214, the rod grip 316 can not overlap with the insertion space 214 in the vertical direction. When the cover 310 opens the insertion space 214, the rod grip 316 can protrude toward the rod support protrusion 306a and can overlap with the insertion space 214 in the vertical direction. When the rod 400 passes through the insertion hole 304 toward the insertion space 214, the rod grip 316 can be free from being jammed by or contacting the rod 400. After the rod 400 is inserted into the insertion space 214, the rod grip 316 can support the outer peripheral surface of the rod 400.

[0430] The bar gripper 316 may have a concave shape to correspond to a portion of the outer peripheral surface of the insertion space 214 (see [reference]). Figure 75 The rod grip 316 may have a shape corresponding to a portion of the outer peripheral surface of the rod 400. The outer peripheral surface of the insertion space 214 may include a shape corresponding to the outer peripheral surface of the rod 400. When the cover 310 opens the insertion space 214, the rod grip 316 may be parallel or aligned with a portion of the outer peripheral surface of the insertion space 214. The inner peripheral surface of the inner wall 212 of the first container 210 and the rod grip 316 may be in close contact with the outer peripheral surface of the rod 400 inserted into the insertion space 214, thereby supporting or surrounding the outer peripheral surface of the rod 400.

[0431] When the cover 310 opens the insertion space 214, the rod support protrusion 306a can face the area between the protrusion 313a and the rod grip 316. When the cover 310 opens the insertion space 214, the rod support protrusion 306a can be positioned at a height corresponding to the position between the protrusion 313a and the rod grip 316. The rod 400 inserted into the insertion space 214 can contact and be supported by all of the protrusion 313a, the rod grip 316, and the rod support protrusion 306a.

[0432] When the cover 310 opens the insertion space 214, the outer peripheral surfaces of the protrusion 313a, the rod gripping part 316, and the lower part of the insertion space 214 can be parallel to each other. The rod 400 inserted into the insertion space 214 can contact and be supported by all of the protrusion 313a, the rod gripping part 316, and the outer peripheral surfaces of the lower part of the insertion space 214.

[0433] A cover support wall 307 may be formed in the cap 300 at a position adjacent to the cover 310. The cover support wall 307 may be positioned opposite the rod support protrusion 306a relative to the lower insertion hole 3040. The cover support wall 307 may face downward into the insertion hole 3040. The cover support wall 307 may be positioned adjacent to the lower side of the shaft 311.

[0434] When the cap 310 pivots in the first direction to open the insertion hole 304, the cap support rod 317 can contact and be supported by the cap support wall 307. When the cap support rod 317 contacts the cap support wall 307, it prevents the cap 310 from moving further in the first direction. When the cap support rod 317 is supported by the cap support wall 307, the cap 310 can be spaced apart from, rather than in contact with, the inner wall 212 surrounding the cap recess 215 of the first container 210.

[0435] The width W10 or diameter W10 of the lower end of the insertion space 214 can be smaller than the width W20 or diameter W20 of the insertion hole 304. The width direction can be perpendicular to the longitudinal direction of the insertion space 214. When the cover 310 opens the insertion hole 304, the distance W10 in the width direction between the rod gripping part 316 and the rod support protrusion 306a can be approximately equal to the width W10 or diameter W10 of the insertion space 214. When the cover 310 opens the insertion hole 304, the distance W10 in the width direction between the protrusion 313a of the front cover surface 313 and the rod support protrusion 306a can be approximately equal to the width W10 or diameter W10 of the insertion space 214.

[0436] The width of the insertion space 214 may gradually decrease downwards. The insertion space 214 may have a conical shape. The width W10 or diameter W10 of the lower end of the insertion space 214 may be smaller than the width W30 or diameter W30 of the upper end of the insertion space 214. The outer wall 211 and inner wall 212 of the first container 210 surrounding the insertion space 214 may be inclined such that the distance between the outer wall 211 and the inner wall 212 gradually decreases downwards.

[0437] The diameter W10 of the lower end of the insertion space 214 can be approximately equal to the diameter W10 of the outer peripheral surface of the rod 400. The diameter W20 of the insertion hole 304 can be larger than the diameter W10 of the outer peripheral surface of the rod 400. The diameter W30 of the upper end of the insertion space 214 can be larger than the diameter W10 of the outer peripheral surface of the rod 400. Based on the width direction, the distance W10 between the rod gripping portion 316 and the rod support protrusion 306a can be approximately equal to the diameter W10 of the outer peripheral surface of the rod 400. Based on the width direction, the distance W10 between the protrusion 313a of the front cover surface 313 and the rod support protrusion 306a can be approximately equal to the diameter W10 of the outer peripheral surface of the rod 400.

[0438] When the rod 400 is inserted into the insertion space 214, the rod 400 can pass through the insertion hole 304 and can slide downwards while contacting at least one of the insertion hole wall 305, shaft 311, rod grip 316, front cover surface 313, second rod guide 306, or rod support protrusion 306a. When the rod 400 is inserted into the insertion space 214, the rod 400 can slide downwards along the outer peripheral surface of the insertion space 214.

[0439] When the rod 400 is inserted into the insertion space 214, the protrusion 313a of the front cover surface 313 can contact one side of the outer peripheral surface of the rod 400 and support one side of the outer peripheral surface of the rod 400. When the rod 400 is inserted into the insertion space 214, the rod gripping part 316 (see...) Figure 75 and Figure 77 A portion of the outer peripheral surface of the rod 400 may surround and support it. When the rod 400 is inserted into the insertion space 214, the rod support protrusion 306a (see...) Figure 78 The first container 210 can surround and support a portion of the outer peripheral surface of the rod 400. When the rod 400 is inserted into the insertion space 214, the outer wall 211 and inner wall 212 of the first container 210 surrounding the lower end of the insertion space 214 can be in close contact with and surround the lower end of the rod 400.

[0440] Therefore, the rod 400 can be easily inserted into the insertion space 214. Furthermore, with the rod 400 fully inserted into the insertion space 214, the position of the rod 400 can be stably fixed.

[0441] Reference Figure 81 Light LT can be emitted from light source 153 of PCB assembly 150' (see Figure 59 The first container 210 may be formed of a transparent or translucent material through which light LT passes. The sidewall 301 of the cap 300 may be formed of a transparent or translucent material through which light LT passes.

[0442] At least a portion of the light LT emitted from the light source 153 may travel toward the outer wall 211 of the first container 210. The light LT traveling toward the outer wall 211 of the first container 210 may be defined as first light LT1. At least a portion of the light LT emitted from the light source 153 may travel toward the upper wall 213 and the cap inlet 304a of the first container 210. The light LT traveling toward the upper wall 213 and the cap inlet 304a of the first container 210 may be defined as second light LT2.

[0443] A cap inlet 304a may be formed at a portion of the upper end of the cap 300. The cap inlet 304a may include a first cap inlet 3041. The cap inlet 304a may include a second cap inlet 3042. The cap inlet 304a may include a third cap inlet 3043. The first cap inlet 3041 may be located above the second cap inlet 3042. The second cap inlet 3042 may be located between the first cap inlet 3041 and the third cap inlet 3043. The third cap inlet 3043 may be located below the second cap inlet 3042. The second cap inlet 3042 may communicate with both the first cap inlet 3041 and the third cap inlet 3043. The first cap inlet 3041 may communicate with the outside of the aerosol generating device. The third cap inlet 3043 may be connected to the upper end of the second channel P2.

[0444] The entrance wall 308 can be formed to have a height corresponding to the cap entrance 304a. The entrance wall 308 can be formed in the heads 330 and 340 of the cap 300. The entrance wall 308 can cover or surround one side of the cap entrance 304a. The upper portion of the side wall 301 of the cap 300 can cover or surround the other side of the cap entrance 304a. The cap entrance 304a can be surrounded by the upper portion of the side wall 301 of the cap 300 and the entrance wall 308. The first container 210 can be located between the cap entrance 304a and the light source 153.

[0445] The entrance wall 308 may include a first entrance wall 3081, a second entrance wall 3082, and a third entrance wall 3083. The first entrance wall 3081 may be formed at a height corresponding to the first cap entrance 3041. The first entrance wall 3081 may cover or surround one side of the first cap entrance 3041. The second entrance wall 3082 may be disposed below the first entrance wall 3081. The second entrance wall 3082 may be disposed between the first entrance wall 3081 and the third entrance wall 3083. The second entrance wall 3082 may be connected to the first entrance wall 3081 and the third entrance wall 3083. The second entrance wall 3082 may be formed at a height corresponding to the second cap entrance 3042. The second entrance wall 3082 may cover or surround one side of the second cap entrance 3042. The third entrance wall 3083 may be disposed below the second entrance wall 3082. The third entrance wall 3083 may be formed at a height corresponding to the third cap entrance 3043. The third entrance wall 3083 may cover or surround one side of the third cap entrance 3043.

[0446] The light-shielding member 307 can protrude from the side wall 301 of the cap 300 toward the interior of the cap inlet 304a. The light-shielding member 307 can be positioned above the second channel P2. The light-shielding member 307 can be positioned between the cap inlet 304a and the second channel P2. The light-shielding member 307 can be positioned above the upper wall 213 of the first container 210. The light-shielding member 307 can be made of a light-blocking material.

[0447] A light-shielding member 307 may be formed at a position corresponding to the third cap inlet 3043 and the third inlet wall 3083. The light-shielding member 307 may protrude from the upper portion of the side wall 301 of the cap 300 to the third cap inlet 3043. The light-shielding member 307 may be disposed between the second cap inlet 3042 and the second channel P2. The side surface of the light-shielding member 307 may face the third cap inlet 3043 and the third inlet wall 3083. The third cap inlet 3043 may be surrounded by the light-shielding member 307 and the third inlet wall 3083. The light-shielding member 307 may be disposed below the first cap inlet 3041 and the second cap inlet 3042, and may cover at least a portion of the lower portion of the first cap inlet 3041 and the second cap inlet 3042.

[0448] The width of the light-shielding member 307 protruding toward the third cap inlet 3043 can be approximately equal to or approximately equal to the width of the first cap inlet 3041. The first cap inlet 3041 can completely overlap with the light-shielding member 307 in the vertical direction. The second inlet wall 3082 and the third inlet wall 3083 may not overlap with the light-shielding member 307 in the vertical direction. The ends of the light-shielding member 307 and the ends of the first inlet wall 3081 can intersect or overlap with each other in the vertical direction.

[0449] The first entrance wall 3081 may protrude further toward the cap entrance 304a than the second entrance wall 3082.
