The inner surface 1511 may be closer to the substrate insertion hole 154 than the upper surface 1512.

[0064] The first sealing portion 151 may include a substrate guide surface 1513. The substrate guide surface 1513 may be formed between the inner surface 1511 and the upper surface 1512. The substrate guide surface 1513 may extend in the longitudinal direction of the first sealing portion 151. The substrate guide surface 1513 may be inclined downward from the upper surface 1512 toward the inner surface 1511. The substrate guide surface 1513 may face the substrate insertion hole 154. The substrate guide surface 1513 may be inclined downward so that the substrate insertion hole 154 gradually narrows downward. Therefore, even if the second substrate 162 comes into contact with the first sealing portion 151, it can be guided by the substrate guide surface 1513 to penetrate the substrate insertion hole 154.

[0065] The coupling groove 1515 may be formed on the lower surface of the first sealing portion 151. The coupling groove 1515 may open downwards.

The substrate insertion hole 154 is located above the first space S1 and can communicate with the first space S1.

[0068] Therefore, the sealing member 150 can be connected to the extension 140 and stably fixed.

[0069] The first sensor 161 can be housed in the housing groove 1565 and in close contact with the sensor housing portion 156. The first sensor 161 can face downward within the sensor housing portion 156. The first sensor 161 can be connected to the outside through the first sensing hole 144 and the second sensing hole 1564. The second substrate 162 (or the second sensor 162) can be inserted into the first space S1 by passing through the substrate insertion hole 154.

[0070] The first connector 126 may be exposed from the first space S1 to the extension 140. The first connector 126 may be exposed upward through the substrate insertion hole 154 of the sealing member 150 coupled to the extension 140. The second connector 166 mounted on the third substrate 163 may be electrically connected by contact with the first connector 126 exposed through the substrate insertion hole 154.

The inner plate 171 can cover at least a portion of the upper part of the pipe 130. The inner plate 171 can support the sealing member 150, the sensor assembly 160 and the pipe 130 and prevent them from separating.

[0073] Screw through holes 1741 and 1742 can be formed by openings in the inner plate 171. Screws 1771 and 1772 can be fastened through the screw through holes 1741 and 1742 into screw fastening holes 137 and 147, thereby joining the inner plate 171 to the upper body 120. Screws 1771 and 1772 can press the inner plate 171 downwards by screwing them into the screw fastening holes 137 and 147. The inner plate 171 may be positioned inside the rim portion 142.

[0074] The first screw through-hole 1741 may be formed on one side of the inner plate 171. Multiple first screw through-holes 1741 may be formed. Each of the multiple first screw through-holes 1741 may be formed at a position corresponding to each of the multiple first screw fastening holes 137.

[0076] The pressing projection 175 may protrude downward from the lower surface of the inner plate 171. The pressing projection 175 may extend along the edge of the sealing member 150 and around the sensor housing 156. The pressing projection 175 can press against the sealing member 150.

[0077] The pressing projection 175 may include a first pressing portion 1751. The first pressing portion 1751 may be formed in a position corresponding to the first sealing portion 151. The first pressing portion 1751 may extend along the first sealing portion 151. The width of the first pressing portion 1751 may be less than the width of the upper surface of the first sealing portion 151. The first pressing portion 1571 can press the upper surface of the first sealing portion 151 downwards.

[0078] The pressing projection 175 may include a second pressing portion 1752. The second pressing portion 1752 may extend along the periphery of the sensor housing portion 156 formed in the second sealing portion 152. The second pressing portion 1752 can press downwards against the upper surface of the second sealing portion 152 formed around the sensor housing portion 156.

[0079] The pressing projection 175 may include a third pressing portion 1753. The third pressing portion 1753 can connect the first pressing portion 1751 and the second pressing portion 1752. Each of the pair of third pressing portions 1753 may be formed at a position corresponding to each of the pair of third sealing portions 153. The third pressing portion 1753 may extend along the third sealing portion 153. The width of the third pressing portion 1753 may be less than the width of the upper surface of the third sealing portion 153. The third pressing portion 1753 can press the upper surface of the third sealing portion 153 downwards.

[0080] Therefore, the inner plate 171 can press the sealing member 150 downwards and make close contact with the sealing member 150. In addition, the first and second spaces S1 and S2 can be sealed, preventing foreign matter such as liquids from flowing into the first and second spaces S1 and S2, and protecting the connector 126 and sensor assembly 160 from external foreign matter.

[0081] Furthermore, since one side of the inner cover 170 is connected to the extension 140 and the other side of the inner cover 170 is connected to the pipe 130, the upper part of the pipe 130 inserted into the upper body 120 is supported, and the pipe 130 can be stably fixed. In addition, the sealing member 150 can be stably fixed.

[0082] Referring to Figures 9 to 12, the outer cover 180 may be positioned on the upper part of the upper body 120 and the upper part of the extension 140. The outer cover 180 can be coupled to the upper body 120 and / or the extension 140. The outer cover 180 may be positioned inside the rim portion 142.

[0083] The outer cover 180 may include an outer plate 181. The outer plate 181 can be positioned inside the rim portion 142 to cover the inner cover 170 and the pipe 130. The periphery of the outer plate 181 can contact or be tightly fitted to the inner circumferential surface of the rim portion 142. A cover hole 184 may be formed by opening one side of the outer plate 181 vertically. The cover hole 184 may correspond to the opening of the insertion space 134.

[0084] The cover coupling groove 185 may be formed on the underside of the outer plate 181. Multiple cover coupling grooves 185 may be provided. The cover coupling groove 185 may be located adjacent to the edge of the outer plate 181. The cover coupling groove 185 may open in a lateral direction intersecting the vertical direction.

[0085] The hook 186 may protrude downward from the outer plate 181. Multiple hooks 186 may be provided. The hook 186 may be positioned adjacent to the edge of the outer plate 181.

[0086] The cover coupling projection 125 may protrude inward from the inner circumferential surface of the rim portion 142 around the upper part of the pipe 130. Multiple cover coupling projections 125 may be formed. The cover coupling projection 125 may correspond to the cover coupling groove 185. Therefore, by inserting the cover coupling projection 125 into the cover coupling groove 185, one side of the outer cover 180 and the upper body 120 can be coupled to each other.

[0087] The hook engagement groove 176 can be formed on one side of the inner plate 171. The hook engagement groove 176 can open laterally. The hook 186 can be inserted into the hook engagement groove 176 and engage with the inner plate 171. Thus, the other side of the outer cover 180 and the inner cover 170 can be coupled to each other, and the other side of the outer cover 180 can be fixed to the extension 140 side.

[0088] The upper body 120 can seal the gap between the pipe 130 and the outer wall 121 or between the pipe 130 and the rim portion 142. The upper body 120 can seal the gap between the pipe 130 and the partition wall 125. The upper body 120 can seal the gap between the pipe 130 and the inner plate 171. The upper body 120 can seal the gap between the inner plate 171 and the rim portion 142. The upper body 120 can seal the gap between the sealing member 150 and the rim portion 142.

[0089] Therefore, the upper body 120 and the upper exterior of the extension can be formed, and foreign matter can be prevented from flowing into the gaps between the components from the outside.

[0090] The second terminal 178 can be coupled to the inner plate 171. The inner plate 171 can be formed by injection molding onto the second terminal 178. The upper end of the second terminal 178 may protrude and be exposed on the upper side of the inner plate 171. The lower end of the second terminal 178 may protrude and be exposed on the lower side of the inner plate 171. The second terminal 178 may be conductive. The lower part of the second terminal 178 may be electrically connected by contact with the first terminal 168 coupled to the second connector 166.

[0091] The first terminal hole 188 may be formed by opening one side of the outer plate 181. The first terminal hole 188 may correspond to the second terminal 178. The upper end of the second terminal 178 may be exposed on the upper side of the outer cover 180 through the first terminal hole 188.

[0092] Referring to Figures 3 and 13, the sensor assembly 160 may be located in a space separate from the pipe 130 and the cartridge 300. The sensor assembly 160 may be located in a first space S1 and a second space S2. The second substrate 162 (or second sensor 162) may be located in the first space S1. The first sensor 161 may be located in the second space S2. The third substrate 163 may be located in the second space S2. The first connector 126 may be exposed from the first space S1 to the second space S2 (see Figure 6). The second connector 166 may be located in the second space S2. The second connector 166 may be connected to the first connector 126 in the second space S2.

[0093] The first sealing portion 151 may be positioned between the first bulkhead portion 1251 and the inner plate 171. The first sealing portion 151 can surround and tightly seal the upper end of the first bulkhead portion 1251. The first sealing portion 151 can tightly seal the lower end of the inner plate 171.

[0094] The sensor housing portion 156 of the second sealing portion 152 can seal the area around the first sensing hole 144. The sensor housing portion 156 can be in close contact with the extension plate 141 around the first sensing hole 144. The second sensing hole 1564 formed in the sensor housing portion 156 can communicate with the first sensing hole 144. The sensor housing portion 156 can surround and tightly contact the first sensor 161.

[0095] Therefore, it is possible to prevent foreign matter or aerosols discharged from around the opening of the pipe 130 from flowing into the first space S1. Furthermore, it is possible to prevent foreign matter from flowing into the second space S2 through the first sensing hole 144. In addition, it is possible to prevent failure of the substrate or sensor.

[0096] Referring to Figure 14, the upper case 200 may include an outer case 210. The upper case 200 may include an inner case 220. The upper case 200 may include a grounding substrate 230.

[0097] The outer case 210 can form the outer shape of the upper case 200. The outer case 210 may have a hollow shape with an open bottom. The outer case 210 may include side walls 211 that form the periphery of the hollow and an upper wall 212 that covers the top of the hollow.

[0098] An outer window 216 may be formed in the side wall 211 of the outer case 210. The outer window 216 may extend vertically. The outer window 216 may be formed in a position corresponding to the first chamber C2 of the cartridge 300. The first outer insertion opening 214 and slide hole 213 may be formed in the upper wall 212. A cap 215 for opening and closing the first insertion opening 214 may be installed on the upper wall 212 of the outer case 210.

[0099] The inner case 220 can be inserted into and joined to the hollow of the outer case 210. The inner case 220 can surround the hollow of the upper case 200. The inner case 220 may have a hollow shape with an open bottom. The inner case 220 may include side walls 221 that form the periphery of the hollow and an upper wall 222 that covers the top of the hollow.

[0100] An inner window 226 may be formed in the side wall 221 of the inner case 220. The inner window 226 may extend vertically. The inner window 226 may correspond to the outer window 216. A second insertion opening 224 may be formed by an opening in the upper wall 222 of the inner case 220. The second insertion opening 224 may correspond to the first insertion opening 214. A rail 223 may extend in the upper wall 222 of the inner case 220 in the direction in which the slide hole 213 extends. The rail 223 supports the lower part of the cap 215 and can guide the cap 215 to move along the slide hole 213.

[0101] The grounding substrate 230 can extend along the perimeter of the side wall 221 of the inner case 220, forming a perimeter. The grounding substrate 230 can surround the outside of the side wall 221 of the inner case 220. The grounding substrate 230 can be positioned between the inner case 220 and the outer case 210. The grounding substrate 230 can be used to ground the second sensor 162 (see Figure 6).

[0102] The incision space 236 can be formed by cutting the grounding substrate 230. The incision space 236 can be formed in a position corresponding to the inner window 226 and the outer window 216. The size of the incision space 236 is larger than the inner window 226 and the outer window 216, and the grounding substrate 230 does not need to cover the inner window 226 and the outer window 216.

[0103] Referring to Figure 15, the grounding substrate 230 can be bent to form an inward space 234. The grounding substrate 230 may be flexible. The grounding substrate 230 may be an FPCB (Flexible Printed Circuit Board). The size of the gap 237 and space 234 formed between both ends of the grounding substrate 230 may vary.

[0104] The grounding substrate 230 may include a connecting portion 232. The connecting portion 232 may be formed at the upper end of the grounding substrate 230. The connecting portion 232 may be formed by bending inward from one upper end of the grounding substrate 230 toward the space 234. The connecting portion 232 may be bent in the inward thickness direction of the grounding substrate 230. The connecting portion 232 may be conductive. A third terminal 238 may be attached to the connecting portion 232. The third terminal 238 may extend downward from the lower surface of the connecting portion 232. The third terminal 238 may be a conductive terminal of clip type or pogo pin type (see Figure 22). The third terminal 238 may be electrically connected to the grounding substrate 230.

[0105] Referring to Figure 16, the second terminal hole 228 can be formed by opening one side of the upper wall 222 of the inner case 220 vertically. The second terminal hole 228 may correspond to the third terminal 238. The second terminal hole 228 can be formed adjacent to the edge of the upper wall 222. The engaging projection 227 can project from the upper wall 222 onto the upper side of the second terminal hole 228.

[0106] The ribs 2231 and 2232 may project outward in the thickness direction from the side wall 221 of the inner case 220. The ribs 2231 and 2232 may extend along the periphery of the side wall 221 to form a periphery.

[0107] The first rib 2231 may be adjacent to the upper wall 222 of the inner case 220. The first rib 2231 may be formed at the upper end of the inner case 220. The first rib 2231 may protrude from the side wall 221 and form a first locking step 2231a on its lower side.

[0108] The second rib 2232 may be separated downward from the first rib 2231. The second rib 2232 may be formed at the lower end of the inner case 220. The second rib 2232 may protrude from the side wall 221 to form a second locking step 2232a on its upper side. The connecting projection 225 may protrude from the second rib 2232. Multiple connecting projections 225 may be arranged along the circumferential direction of the second rib 2232.

[0109] Referring to Figures 17 to 19, the grounding substrate 230 can be coupled to the inner case 220 and cover the side wall 221 of the inner case 220. The cutout space 236 may correspond to the inner window 226.

[0110] When the grounding substrate 230 is coupled to the inner case 220, the connecting portion 232 above the third terminal 238 can be inserted into the second terminal hole 228 and cover the second terminal hole 228. The third terminal 238 can be exposed downwards through the second terminal hole 228. Thus, the third terminal 238 can be exposed toward the hollow 204 inside the inner case 220 (see Figure 20).

[0111] The engaging projection 227 may be positioned above the connecting portion 232. The upper surface of the connecting portion 232 can engage with the engaging projection 227. The engaging projection 227 can restrict the vertical movement of the connecting portion 232. Thus, it is possible to prevent the connecting portion 232 and the third terminal 238 from detaching upward from the second terminal hole 228, and to fix the positions of the connecting portion 232 and the third terminal 238.

[0112] The grounding substrate 230 may be positioned between the first rib 2231 and the second rib 2232. The upper end of the grounding substrate 230 may be located below the first rib 2231. The upper end of the grounding substrate 230 may be supported by the first locking step 2231a of the first rib 2231. The lower end of the grounding substrate 230 may be located above the second rib 2232. The lower end of the grounding substrate 230 may be supported by the second locking step 2232a of the second rib 2232.

[0113] The inner case 220 and the grounding substrate 230 can be inserted into the hollow of the outer case 210. The inner case 220 and the outer case 210 can be coupled together.

[0114] The connecting projection 225 is inserted into a groove formed on the inside of the outer case 210, thereby allowing the side wall 221 of the inner case 220 and the side wall 211 of the outer case 210 to be joined in a snap-fit ​​manner. The upper wall 222 of the inner case 220 can be joined to the upper wall 212 of the outer case 210. The first insertion opening 214 and the second insertion opening 224 can correspond to each other. The inner window 226 and the outer window 216 can correspond to each other.

[0115] The periphery of the grounding substrate 230 may be positioned between the side wall 211 of the outer case 210 and the side wall 221 of the inner case 220. The side wall 211 of the outer case 210 can cover the outer circumferential surface of the grounding substrate 230. The side wall 221 of the inner case 220 can cover the inner circumferential surface of the grounding substrate 230. The ribs 2231 and 2232 can contact the side wall 211 of the outer case 210 and block the space through which the upper and lower ends of the grounding substrate 230 can move. The connecting portion 232 may be positioned between the upper wall 222 of the inner case 220 and the lower wall 212 of the outer case 210.

[0116] Therefore, the position of the grounding substrate 230 can be fixed, and it is possible to prevent the grounding substrate 230 from detaching from the inner case 220.

[0117] Referring to Figures 20 to 22, the third terminal 238 may be exposed through the hollow 204 of the upper case 200. The third terminal 238 may face the hollow 204 from inside the upper case 200. The third terminal 238 may be exposed through the hollow 204 at the top of the upper case 200 and extend downwards. The third terminal 238 may protrude from the inner case 220 into the hollow 204. The third terminal 238 may be a clip-type or pogo-pin type conductive terminal.

[0118] The upper case 200 can be detachably coupled to or mounted on the upper body 120. When the upper case 200 is separated from the upper body 120, the third terminal 238 can be detached from the second terminal 178 and no longer electrically connected. When the upper case 200 is mounted on the upper body 120, the upper case 200 can cover the upper body 120 so as to surround it. The grounding substrate 230 can cover the upper body 120 so as to surround it. The grounding substrate 230 can surround the second sensor 162 (see Figure 6). When the upper case 200 is mounted on the upper body 120, the third terminal 238 can be electrically connected by contacting the upper end of the second terminal 178. The third terminal 238 can be electrically connected to the first terminal 168.

[0119] Therefore, when the upper case 200 is coupled to the upper body 120, the grounding substrate 230 and the second sensor 162 are connected to each other, and the second sensor 162 can be grounded via the grounding substrate 230.

[0120] Furthermore, when the second sensor 162 is activated, sensing noise of the second sensor 162 caused by changes in the dielectric constant of the second sensor 162 due to the user's body or other objects in contact with the aerosol generator can be prevented. For example, the grounding substrate 230 connected to the second sensor 162 prevents noise generated around the second sensor 162 from outside the upper case 200, thereby improving accuracy when sensing information about the stick or the remaining amount of liquid stored in the cartridge.

[0121] The windows 216 and 226 are formed in positions corresponding to the first chamber C1 and may extend vertically along the height of the first chamber C1. Through the windows 216 and 226 formed in the upper case 200 of the first chamber C1, the volume or state of the liquid stored in the first chamber C1 of the cartridge 300 can be visually inspected.
