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

[0128] 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 airflow that passes through the gap between the sensor housing 137 and the lower housing 230 and enters the cylinder inlet 224.

[0129] 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 position adjacent to the opposite end or lower end of the insertion space 214. The rod stop 217 may protrude radially inward. The rod stop 217 may be formed on the outer wall 211 and / or inner wall 212 of the first container 210.

[0130] 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 as ribs or rings extending circumferentially along the periphery of the insertion space 214. The rod 400 can be located above the rod stops 217. The rod stops 217 can have a shape that gradually widens in the upward direction.

[0131] 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.

[0132] In addition, the reduction in the amount of air flowing from the second chamber C2 to the insertion space 214 can be minimized.

[0133] Furthermore, the rod stop 217 can prevent the aerosol generated in the second chamber C2 from extracting specific components from the medium in the rod 400.

[0134] Reference Figure 17 and Figure 18 The pivot axis or shaft 311 of the cover 310 may be located above the insertion space 214. The pivot axis or shaft 311 of the cover 310 may be located 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.

[0135] When the cover 310 pivots in the 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 located below the cover recess 215. When the cover 310 opens the insertion space 214, the cover 310 can be positioned parallel to the inner wall 212 of the first container 210 located below the cover recess 215.

[0136] 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 formed to slope such that the insertion space 214 gradually narrows toward its downward side. When the cover 310 opens the insertion space 214, the first guide 216 may be positioned below the cover 310, adjacent to one end of 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.

[0137] 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 in which the cover 310 pivots outward 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 in which the cover 310 closes the insertion space 214. The cover 310 can pivot in the second direction via the spring 312.

[0138] The second guide 306 can be angled so that the internal space gradually narrows towards its lower side. The second guide 306 can be positioned adjacent to the pivot radius of the cover 310. The second guide 306 can be positioned outside the pivot radius of the cover 310. The second guide 306 can extend to be angled along the pivot radius of the cover 310.

[0139] 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 further inward 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, thereby restricting the movement of the cover 310.

[0140] 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, which 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 to slope from one end to the other.

[0141] Reference Figures 19 to 22 The rod 400 can push the cover 310 in the inward direction of the insertion space 214 or in the first direction. When the rod 400 pushes the cover 310 and inserts it into the insertion space 214, the cover 310 can open the insertion space 214 and / or the insertion hole 304.

[0142] Reference Figure 19 and Figure 20 When the end of the rod 400 passes through the insertion hole 304, the 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.

[0143] 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.

[0144] 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 relative to the insertion hole 304, opposite to the pivot axis of the cover 310. 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.

[0145] 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.

[0146] The end of the rod 400 inserted into the insertion space 214 can contact the rod stop 217. The rod stop 217, in contact with the end of the rod 400, can prevent the rod 400 from moving to the area below the insertion space 214 or moving to the second chamber C2.

[0147] 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.

[0148] 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.

[0149] Furthermore, since the rod 400 is in close contact with the wall of the defined insertion space 214, when the user inhales air through the rod 400, unnecessary airflow between the insertion space 214 and the rod 400 can be prevented, and the waste of suction force can be reduced, thereby preventing the deterioration of airflow efficiency.

[0150] Furthermore, even when the user pushes the cover 310 with the stick 400, the cover 310 applies an external force to the end of the stick 400 in the second direction, which can guide the stick 400 to be properly inserted into the insertion space 214.

[0151] In addition, it can prevent rod 400 from moving into the interior of the second chamber C2.

[0152] refer to Figure 23The upper body 120 can be connected to the upper part of the lower body 110. The mounting member 130 can cover the upper part of the lower body 110.

The mounting member 130 can be connected to the upper part of the lower body 110. The mounting member 130 can be connected to the lower body 110 by a snap-fit ​​engagement. The mounting member 130 can engage with the lower body 110 so as not to separate from it.

[0153] The second sensor 180 can be disposed on one side of the upper part of the lower body 110. The sensor support 185 can have a shape that extends upward from the upper part of the lower body 110. The sensor support 185 can support the second sensor 180. The second sensor 180 can be coupled to the sensor support 185. The second sensor 180 can be coupled to the sensor support 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 185.

[0154] Reference Figures 24 to 26 A fastening hole 135 may be formed in the lower part of the mounting member 130. The fastening hole 135 may be formed on the side of the lower part 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 part of the mounting member 130. A body latch 115 provided at the upper part 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 reference). Figure 28 and Figure 29 ).

[0155] A rib groove 136 may be formed in the outer surface 132 of the mounting member 130. The rib groove 136 may have a shape that is recessed inward from the outer surface 132 of the mounting member 130. The rib groove 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 part of the lower body 110 may be inserted into the rib groove 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 groove 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 wobbling relative to the lower body 110 (see reference). Figure 28 and Figure 29 ).

[0156] A first fixing portion 138 may be formed at the lower part of the mounting member 130. The first fixing portion 138 may be recessed upwards or protruded downwards from the lower part of the mounting member 130. The first fixing portion 138 may be formed at the periphery of the lower part 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 part of the mounting member 130. A second fixing portion 118 provided at the upper part 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 the upper body 120 can be prevented from wobbling relative to the lower body 110 (see reference). Figure 28 and Figure 29 ).

[0157] 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 walls 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 recessed shape. The column 140 may face the side of the cylinder 200 (see reference). Figure 6 The column 140 may cover one side of the cylinder 200. The column 140 may have an opening toward one side of the cylinder 200.

[0158] The column 140 may house the PCB assembly 150. The PCB assembly 150 may provide light to the cylinder 200 or may 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 in the first chamber C1 stored in 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 in the cylinder 200; information about the type of rod 400 inserted into the insertion space 214 in the cylinder 200; information about the degree of use or availability of the rod 400 inserted into the insertion space 214 in 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 can accommodate a first sensor 154, which is configured to sense information about the cylinder 200.

[0159] The column 140 may provide 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 a space 134 in the mounting member 130. The installation space 144 may open toward a side of the cylinder 200.

[0160] 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.

[0161] 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.

[0162] PCB assembly 150 can be disposed inside post 140 to face cylinder 200. PCB assembly 150 can face first container 210, which has a first chamber C1 and an insertion space 214. PCB assembly 150 can extend vertically along post 140. Connector 152 for electrical connection can be formed at one end of PCB assembly 150.

[0163] 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.

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.

[0164] Therefore, the light source 153 can provide uniform light to the first chamber C1.

[0165] 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.

[0166] 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.

[0167] 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.

[0168] 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.

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.

[0170] The shape of the surface 171a of window 170 may correspond to the shape of the outer wall 211 of the first container 210 forming the periphery of insertion space 214. Insertion space 214 may be adjacent to pillar 140 and PCB assembly 150 (see reference). Figure 15 The 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 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.

[0171] At least one recess 174 for 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.

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.

[0172] The opposing surface 171b of window 170 may include a flat portion 172, which is formed to be flat. The flat portion 172 can be in close contact with PCB assembly 150. The flat portion 172 can be inserted into the mounting space 144 in post 140 (see reference). Figure 24 The light source recess 174 can be formed by pressing the flat portion 172.

[0173] 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 part of the PCB 151. The through holes 151a may be located above the light source 153 and / or the first sensor 154.

[0174] Window 170 may include a plurality of through protrusions 172a. The through protrusions 172a may project from an opposing surface 171b of window 170. The through protrusions 172a may be formed at locations corresponding to vias 151a. The through protrusions 172a may project toward the via 151a. The through protrusions 172a may pass through the via 151a. A plurality of through protrusions 172a may be provided. Each of the plurality of through protrusions 172a may pass through a corresponding one of the plurality of vias 151a. Because the through protrusions 172a may pass through the vias 151a, PCB assembly 150 and window 170 can be positioned correctly.

[0175] Window 170 may include latching protrusions 173. Latching protrusions 173 may be formed on opposing surfaces 171b of window 170. Latching protrusions 173 may project from each side of the flat portion 172. Multiple latching protrusions 173 may be provided, and the multiple latching protrusions 173 may be arranged vertically.

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 provided as a pair, 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 thereto. The side flange portions 1451, lower flange portions 1452, and upper flange portions 1453 may be connected to each other to form the periphery of the flange 145. The area surrounded by the side flange 1451, the lower flange 1452 and the upper flange 1453 can be opened, so that the component receiving space 144 and the cylinder receiving space 134 can communicate with each other.

[0178] 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 component. The adhesive component can be, for example, a piece of tape or glue. The adhesive component is not limited thereto. Latch protrusion 173 can engage with flange 145, thus window 170 can be connected 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.

[0179] Therefore, the PCB assembly 150 can be protected from external influences and the PCB assembly 150 can be prevented from separating.

[0180] In addition, light emitted from PCB assembly 150 can be provided to tube 200.

[0181] In addition, the window 170, the cylinder 200 and the PCB assembly 150 can be reliably connected or fixed to each other.

[0182] 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 through which electromagnetic waves pass may not allow visible light to pass, or may be translucent.

[0183] 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 printed 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 further extends from its vertical extension toward the printed circuit.

[0184] Board 160 may expose the light source 153, rather than cover it. The light source 153 may be positioned on either side of the first sensor 154, with the first sensor 154 inserted between them, and the light source 153 may be arranged vertically. A 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 opening in board 160.

[0185] 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.

[0186] In addition, the first sensor 154 can sense changes in the electromagnetic properties of the surrounding environment while it is covered by the plate 160.

[0187] refer to Figure 27 PCB assembly 150 can be disposed inside post 140 and can extend along post 140. PCB 151 can extend along post 140.

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 the 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.

[0189] The inner surface 131 of the sensor receiving portion 137 can be opened to form a sensing hole 137a. The sensing hole 137a can 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 can be adjacent to the cylinder inlet 224 (see reference). Figure 15 The sensing port 137a can face the cylinder inlet 224.

[0190] The sensing aperture 137a can be open in the lateral direction. The side of the second container 220 can be opened to form a cylinder inlet 224, and the sensing aperture 137a, which is open in the lateral direction, can face the cylinder inlet 224 (see reference). Figure 15 ).

The partition wall 112 can be disposed in the upper part of the lower body 110 in a direction intersecting with the side wall 111 of the lower body 110. The partition wall 112 can cover the upper side of the internal components of the lower body 110. The partition wall 112 can separate the space in which the internal components of the lower body 110 are installed from the space in which the upper body 120 is connected. The partition wall 112 can be disposed below the upper body 120. The side wall 111 of the lower body 110 can extend upward beyond the partition wall 112 and can surround the periphery of the partition wall 112.

The core retainer 2526 can be in close contact with the core 261 and the sidewall 2421 of the second frame portion 242, wherein the core insertion recess 2426 is formed.

[0262] 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.

[0263] refer to Figure 40 The connecting space 2417 can interconnect the first chamber C1 and the second chamber C2. The connecting space 2417 can be formed between the first chamber C1 and the second chamber C2, or it can be formed in the portion of the first chamber C1 adjacent to the second chamber C2. The connecting space 2417 can be referred to as the chamber connecting space 2417.

[0264] The end of the core 261 can be disposed in the connecting space 2417. The end of the core 261 can pass through the gap between the core insertion recess 2426 and the core holder 2526 and can be exposed in the connecting space 2417. The connecting spaces 2417 can be configured as a pair. Each of the pair of connecting spaces 2417 can be disposed adjacent to a corresponding one of the two ends of the core 261. The pair of connecting spaces 2417 can be formed between the first sealing portion 251 and the second sealing portion 252. An inclined portion 2416 can be formed below the connecting space 2417. Each of the pair of inclined portions 2416 can be formed below a corresponding one of the pair of connecting spaces 2417.

[0265] refer to Figure 41 and Figure 42 The sidewall 2421 of the second frame portion 242 may surround the side 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.

[0266] The lower support surface 2522 and the side support surface 2523 can surround and be in close contact with the lower edge of the inner wall 212 of the first container 210. The lower support surface 2522 can support the lower end surface of the inner wall 212 of the first container 210. The lower support surface 2522 can extend along the periphery of the inner wall 212 of the first container 210.

[0267] 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 the side surface adjacent to the lower end surface of the inner wall 212 of the first container 210.

[0268] The support portion 2428 may be disposed below the inner wall 212 of the first container 210. The support portion 2428 may be positioned along a line extending outward from the inner wall 212 of the first container 210.

[0269] 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 housing 230. The lower end of the outer wall 211 of the first container 210 can be recessed upward so that the peripheral portion 2322 is inserted therein. The outer wall 211 of the first container 210 can be attached to the peripheral portion 2322.

[0270] When the first container 210 is connected to the lower housing 230, the first sealing part 251 can be in close contact with the first frame part 241 and the outer wall 211 of the first container 210.

[0271] When the first container 210 is connected to the lower housing 230, the inner wall 212 of the first container 210 can press the second sealing portion 252 toward the second frame portion 242. When the inner wall 212 of the first container 210 presses the second sealing portion 252, the second sealing portion 252 can come into close contact with 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.

[0272] Therefore, the number of parts connected using adhesive components can be reduced, and the number of components used to connect the various parts can also be reduced. Consequently, the structure of the components used in the connecting cylinder 200 can be simplified, and manufacturing efficiency can be improved.

[0273] 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.

[0274] Reference Figure 43Multiple first uneven portions 2515 can 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 can be in close contact with the outer wall 211 of the first container 210.

[0275] 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.

[0276] Therefore, the first sealing part 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 of the side wall 2412 of the first frame part 241.

[0277] At least one of the first uneven portions 2515 may be formed at the height of the second portion 2512 corresponding to the height 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 the height corresponding to the second portion 2512.

[0278] Therefore, when the outer wall 211 of the first container 210 is connected to the lower housing 230, the second part 2512 of the first sealing part 251 can receive inward and downward forces, thereby pressing down on the upper part of the side wall 2412 of the first frame part 241.

[0279] In addition, the entire first sealing part 251 can be in close contact with the outer wall 211 and the first frame part 241 of the first container 210, thereby preventing liquid leakage.
