[0030] Terms including ordinal numbers, such as "first," "second," etc., can be used to describe a variety of components, but it should be understood that the components are not limited by such terms. These terms are used solely for the purpose of distinguishing one component from another.

[0031] When we say that one component is "linked" to another, it is understandable that other components may exist in between. On the other hand, when we say that one component is "directly linked" to another, it is understandable that there are no other components in between.

[0032] A singular expression includes plural expressions unless explicitly indicated otherwise in the context.

[0033] Referring to Figure 1, the aerosol generator can include a body 10 and cartridges 20 and 30. The cartridges 20 and 30 can include a first container 20 and a second container 30. The cartridges 20 and 30 can be coupled to the body 10.

[0034] The body 10 can house a power supply 11 and a control unit 12. The power supply 11 can supply the power necessary for the configuration to operate. The power supply 11 can be called a battery 11. The control unit 12 can control the operation of the configuration.

[0035] The first container 20 may have a first chamber C1 inside. The first container 20 may be equipped with a core 25. The core 25 may be placed in the first chamber C1. The upper end of the core 25 may protrude from the first chamber C1 to the upper side of the first container 20.

[0036] The first container 20 may be equipped with a heater 2531. The heater 2531 may be located in the first chamber C1. The heater 2531 can heat the wick 25. The heater 2531 may be attached to the wick 25. The first container 20 may be equipped with a terminal 223 inside. The terminal 223 may be exposed on the underside of the first container 20. The terminal 223 may be electrically connected to the heater 2531. The first container 20 may be called the lower container 20 or heating module 20.

[0037] The first container 20 may be equipped with a first airflow inlet 241 formed by opening the first chamber C1. The first container 20 may be equipped with a first airflow outlet 242 formed by opening the first chamber C1.

[0038] The second container 30 can have a second chamber C2 inside. The second container 30 can store liquid in the second chamber C2. The second container 20 can be equipped with an airflow discharge channel 340. Both ends 341, 342 of the airflow discharge channel 340 can be open. The airflow discharge channel 340 can be partitioned from the second chamber C2. The second container 30 can be called the upper container 30 or the liquid storage section 30.

[0039] The mouthpiece 35 can be coupled to the upper side of the second container 30. The mouthpiece 35 can cover the top of the second container 30. The mouthpiece 35 may have a second airflow outlet 354 inside. The second airflow outlet 354 can communicate with the other end 342 of the airflow outlet 340. The mouthpiece 35 can be tilted via an axis to open and close the airflow outlet 340.

[0040] The first container 20 can be coupled to the body 10. The first container 20 can be inserted inside the body 10. When the first container 20 is coupled to the body, the heater 2531 can be electrically connected to the power supply 11 via terminal 223. The heater 2531 can receive power from the power supply 11 and generate heat. The heater 2531 may be a resistive heater.

[0041] The second container 30 can be coupled to the upper side of the first container 20. The coupling of the second container 30 to the first container 20 can include the second container 30 being directly coupled to the first container 20, or the second container 30 being coupled to the body 10 and indirectly coupled to the first container 20.

[0042] When the second container 30 is coupled to the first container 20, the second container 30 can supply the stored liquid to the wick 25. The wick 25 can receive and absorb the liquid from the second container 30. The heater 2531 can heat the wick that has absorbed the liquid to generate an aerosol in the first chamber C1.

[0043] Body 10 can be opened on one side to form a second airflow inlet 141. When the first container 20 is coupled to body 10, the first airflow inlet 241 can communicate with the second airflow inlet 141. When the second container 30 is coupled to the first container 20, one end 341 of the airflow discharge channel 340 and the first airflow outlet 242 can communicate. Thus, a flow path for air can be formed. The user can inhale air by placing the mouthpiece 35 in their mouth. When the user inhales air, the outside air can be supplied to the user by sequentially passing through the second airflow inlet 141, the first airflow inlet 241, the first chamber C1, the first airflow outlet 242, the airflow discharge channel 340, and the second airflow outlet 354. The air can flow together with the aerosol generated in the first chamber C1.

[0044] Therefore, the first container 20 and the second container 30 can be replaced independently of each other. For example, the consumption cycle of the liquid stored in the second container 30 and the appropriate replacement cycle of the first container 20 may differ, and the user can replace only the second container 30 separately, or only the first container 20 separately. For example, the consumption cycle of the liquid stored in the second container 30 may be shorter than the appropriate replacement cycle of the first container 20, and when the second container 30 is replaced several times, the first container 20 may only be replaced once. Therefore, the first container 20 can be used for a longer period, and cartridge replacement costs can be reduced.

[0045] Referring to Figure 2, the first container 20 can be detachably coupled to the body 10. The first coupler 151 can detachably couple the first container 20 and the body 10. For example, the first coupler 151 may include a hook groove 225 and a hook 125 that is detachably fastened to the hook groove 225. The hook 125 may be made of a material such as rubber or silicone and may also seal the space between the body and the first container 20 around the second airflow inlet 141. In another example, the first coupler 151 can couple the first container 20 and the body 10 by magnetic force.

[0046] The second container 30 can be detachably coupled to the first container 20. The second container 30 can be coupled to the upper side of the first container 20. The second container 30 can be coupled to the body 10 and indirectly coupled to the first container 20. The second coupler 152 can detachably couple the second container 30 and the body 10. For example, the second coupler 152 may include a hook groove 325 and a hook 135 that is detachably fastened to the hook groove 325. As another example, the second coupler 152 can couple the second container 30 and the body 10 by magnetic force.

[0047] Referring to Figures 3 to 5, the first container 20 may include a case 21, a wick 25, and a heater 2531. The case 21 may include a first case 22 and a second case 23.

[0048] The second case 23 can be coupled to the upper side of the first case 22. The first case 22 may have an opening on the upper side and a space 224 that forms the first chamber C1. The second case 23 may have an opening on the lower side and a space 234 that forms the first chamber C1. The first case 22 and the second case 23 can be coupled vertically to form the first chamber C1 inside.

[0049] Terminals 223 are fixed to the bottom of the first case 22 and can be exposed on the underside of the first case 22. Terminals 223 can project upward from the first case 22 toward the first chamber C1. Terminals 223 can consist of a pair that are horizontally spaced apart from each other.

[0050] The first airflow inlet 241 may be formed at the bottom of the first case 22. The first airflow inlet 241 may be formed as a plurality of perforated holes.

[0051] Case 21 may comprise one configuration of the first coupler 151 (see Figures 1 and 2). For example, the hook groove 225 may be formed by a recess in the lower periphery of the first case 22. In another example, the hook 125 may be formed by a protrusion in the lower periphery of the first case 22. In yet another example, the first case 21 may comprise a magnet or a ferromagnetic material.

[0052] The first airflow outlet 242 may be formed on the upper wall of the second case 23. As another example, the first airflow outlet 242 may be formed on the side wall of the second case 23. The first airflow outlet 242 may be formed in a position opposite the first airflow inlet 241.

[0053] A liquid inlet 235 may be formed on the upper wall of the second case 23. The liquid inlet 235 may be formed on the upper side of the first chamber C1.

The second core part 252 can protrude upward through the liquid inlet 235 and the first core sealing part 265.

[0056] The heater 2531 can be coupled to the first core part 251. The heater 2531 can heat the first core part 251. The first terminals 2533 formed at both ends of the heater 2531 can contact the second terminals 223, thereby electrically connecting the heater 2531 and the second terminals 233.

[0057] The supporter 227 can protrude upward from the bottom of the first case 22. The supporter 227 may be formed around the terminal 223.

The second supporter 227b may be formed between the terminal 223 and the first airflow inlet 241. The second supporters 227b may be formed as a pair. The pair of second supporters 227b can be separated from each other to form a first gap 227c between them. The first supporter 227a and the second supporter 227b can be separated from each other to form a second gap 227d between them.

[0059] The sealer 26 can be attached to the upper side of the first container 20. The sealing plate 261 of the sealer 26 can cover the upper surface of the case 21. The sealer 26 can be made of an elastic material. For example, the sealer 26 can be made of rubber or silicone material.

[0060] The sealer 26 may include a first core sealing portion 265.

The airflow sealing section 268 may be formed on the outside of the sealing walls 266, 267.

[0064] Referring to Figures 6 and 7, the core 25 can be formed from a porous rigid body that absorbs liquid. For example, the core 25 can be formed from a porous ceramic. The core 25 can have higher rigidity and heat resistance than a cotton core.

[0065] Therefore, the core 25 is not easily deformable and can be embodied in a variety of shapes. In addition, the durability of the core 25 can be improved, and the replacement cycle of the first container 20 equipped with the core 25 can be extended.

The first supporter 227a may extend along the right edge between the lower surface 2513 and the side surface 2512 of the first core part 251. The first supporter 227a may support the right corner between the lower surface 2513 and the side surface 2512 of the first core part 251. A pair of second supporters 227b may support the left corner of the first core part 251.

[0078] A pair of second supporters 227b can be separated from each other to form a first gap 227c through which air can flow between the periphery of the heater 2531 and the first airflow inlet 242. The first supporter 227a and the second supporter 227b can be separated from each other to form a second gap 227d through which air can flow between the periphery of the heater 2531 and the first airflow inlet 242. The first gap 227c and the second gap 227d can be formed around the lower surface 2513 of the first core part 251.

[0079] Therefore, the aerosol generated in the core 25 and the surrounding air can flow smoothly towards the first airflow outlet 242 by passing around the multiple supporters 227.

[0080] The first core sealing portion 265 may be positioned between the circumferential surface 2522 of the second core part 252 and the circumferential surface 235a of the liquid inlet 235. The inner circumferential surface of the first core sealing portion 265 can be in close contact with the circumferential surface 2522 of the second core part 252. The first core sealing portion 265 can seal the space between the circumferential surface 2522 of the second core part 252 and the circumferential surface 235a of the liquid inlet 235.

[0081] The perimeter of the upper surface 2511 of the first core part 251 may be larger than the perimeter of the liquid inlet 235. The perimeter of the upper surface 2511 of the first core part 251 may be formed horizontally outward than the perimeter of the liquid inlet 235. The edge portion of the first core part 251 can absorb liquid leaking between the liquid inlet 235 and the circumferential surface 2522 of the second core part 252.

[0082] The second core sealing portion 262 can protrude downward from the vicinity of the liquid inlet 235 toward the upper surface 2511 of the first core part 251. The second core sealing portion 262 can be in close contact with the upper surface 2511 of the first core part 251. The second core sealing portion 262 can support the upper surface 2511 of the first core part 251.

[0083] Therefore, the liquid supplied from the second container 30 to the core 25 is not absorbed by the core 25 and is prevented from leaking into the first chamber C1 through the space between the second core part 252 and the circumferential surface 235a of the liquid inlet 235.

[0084] Referring to Figures 10 to 12, the second container 30 can provide a second chamber C2 for storing liquid. The second chamber C2 can be defined by the lower wall 311, side walls 321, 322 and upper wall 33 of the second container 30. The side walls 321, 322 can extend vertically. The side walls 321, 322 may include an outer wall 321 forming the exterior of the second container 30 and an inner wall 322 formed inside the second container 30. The inner wall 322 is formed between the second chamber C2 and the airflow discharge channel 340, and can partition the second chamber C2 and the airflow discharge channel 340 from each other.

[0085] The liquid outlet 314 may be formed by opening the second chamber C2. The liquid outlet 314 may be formed at the bottom of the second chamber C2. The liquid outlet 314 may consist of multiple holes. The liquid stored in the second chamber C2 can be discharged through the liquid outlet 314.

[0086] The discharge guide 313 may be formed around the liquid outlet 314. The discharge guide 313 may be formed to slope downward toward the liquid outlet 314. The discharge guide 313 may be formed on the lower surface 311 of the second chamber C2. The discharge guide 313 can guide the liquid stored in the second chamber C2 to the liquid outlet 314.

[0087] The absorbent portion 316 can block the lower part of the liquid outlet 314. The absorbent portion 316 can absorb the liquid that has passed through the liquid outlet 314. For example, the absorbent portion 316 may be made of felt material.

[0088] The bracket 317 can protrude downward from the second container 30 around the liquid outlet 314. The bracket 317 can surround the side perimeter of the absorbent section 316. The absorbent section 316 can be exposed from the bracket 317 to the underside of the second container 30. The bracket 317 can fix the absorbent section 316 to the lower part of the first container 30. The bracket 317 can support the lower perimeter of the absorbent section 316 in a hook shape.

[0089] The film 316a can be detachably attached to the lower surface of the absorbent section 316. The edges of the film 316a can be attached to the lower surface of the bracket 317. The film 316a may be made of a waterproof material. The film 316a can prevent liquid from leaking from the absorbent section 316. Prior to joining the second container 30 to the first container 20, the user can remove the film 316a from the absorbent section 316.

[0090] The recess 315 can be formed by the lower surface 312 of the second container 30 being recessed upward. The groove formed by the recess 315 can surround the bracket 317.

[0091] The second container 30 may have one configuration of the second coupler 152 (see Figures 1 and 2). For example, the hook groove 325 may be formed by a recess in the outer wall 321 of the second container 30. In another example, the hook 135 may be formed by a protrusion of the outer wall 321 of the second container 30. In yet another example, the second container 30 may be equipped with a magnet or a ferromagnetic material.

[0092] The second container 30 may have an airflow discharge channel 340. The airflow discharge channel 340 may be separated from the second chamber C2 by the inner wall 322 of the second container 30. The airflow discharge channel 340 may be defined by the outer wall 321 and the inner wall 322 of the second container 30. Both ends of the airflow discharge channel 340 may be open. One end of the airflow discharge channel 340 may open downwards. The other end of the airflow discharge channel 340 may open upwards. One end of the airflow discharge channel 340 may be formed by an opening in the lower surface 312 of the second container 30. The other end of the airflow discharge channel 340 may communicate with a second airflow outlet 354 formed inside the mouthpiece 35. The airflow discharge channel 340 may be called the second channel CN2.

[0093] Referring to Figures 13 and 14, the first container 20 can be detachably coupled to the body 10. The first coupler 151 can detachably couple the first container 20 and the body 10. The second container 30 can be detachably coupled to the first container 20. The second container 30 can be indirectly coupled to the first container 20 by coupling to the body 10 via the second coupler 152. The second container 30 can be coupled to the upper side of the first container 20.

[0094] When the second container 30 is coupled with the first container 20, the second container 30 can supply liquid to the wick 25. The liquid stored in the second chamber C2 passes through the liquid outlet 314 and is absorbed into the absorbent section 316. The absorbent section 316, having absorbed the liquid, can then come into contact with the second wick part 252 and transfer the liquid. The liquid absorbed into the second wick part 252 can then diffuse to the first wick part 251. The heater 3531 can heat the first wick part 251, which has absorbed the liquid, to generate an aerosol.

[0095] The sealer 26 can seal around the liquid inlet 235 where the core 25 is exposed from the first chamber C1. When the second container 30 is joined to the top of the first container 20, the sealer 26 can seal between the first container 20 and the second container 30.

[0096] The sealing walls 266 and 267 can project toward the second container 30. The sealing walls 266 and 267 can be in close contact with the second container 30. The sealing walls 266 and 267 can surround the liquid inlet 235.

[0097] Therefore, it is possible to prevent the liquid discharged from the second container 30 from leaking into the gap between the first container 20 and the second container 30.

[0098] Referring to Figure 15, the first sealing wall 266 can surround the liquid inlet 235 and the periphery 2522 of the second core part 252. The first sealing wall 266 can be in close contact with the bottom of the second container 30. The first sealing wall 266 can be in close contact with the protruding portion formed inside the recess 266. For example, the first sealing wall 266 can be in close contact with the bracket 317. The bracket 317 and the first sealing wall 266 can surround the periphery 2522 of the second core part 252. Thus, the bracket 317 can not only fix the absorbent part 316 but also press the first sealing wall 266 to seal the periphery of the second core part 252 and the liquid inlet 235.

[0099] The second sealing wall 267 can protrude higher than the first sealing wall 266. The second sealing wall 267 can be positioned horizontally outside the first sealing wall 266 and surround the first sealing wall 266. The second sealing wall 267 can be in close contact with the bottom of the second container 30. The second sealing wall 267 can be inserted into the groove formed by the recess 315 and be in close contact with the recess 315.

[0100] Therefore, the first sealing wall 266 can seal around the second core part 252 and the liquid inlet 235. Furthermore, even if the liquid flows beyond the first sealing wall 266, it can be sealed by the second sealing wall 267.

[0101] Referring to Figures 15 and 16, the first channel CN1 may be formed on the left side of the first chamber C1. The core 25 and heater 2531 may be located on the right side of the first chamber C1. The first channel CN1 may include a first airflow inlet 241 and a first airflow outlet 242. The first airflow inlet 241 may be formed at one end of the first channel CN1. The first airflow outlet 242 may be formed at the other end of the first channel CN1. The first channel CN1 may be offset from the core 25 with respect to the vertical. The core 25 may be spaced apart from the first airflow inlet 241 and the second airflow inlet 242. Unlike the illustrations, at least one of the first airflow inlet 241 and the first airflow outlet 242 may be formed by an opening in the side wall of the first container 20 in the first channel CN1.

[0102] When the first container 20 is coupled to the body 10, the second airflow inlet 141, which is formed by an opening on one side of the body 10, can communicate with the first airflow inlet 241. The gap between the body 10 and the first container 20 can be sealed around the second airflow inlet 141. For example, a hook 125 can seal the gap between the body 10 and the first container 20 around the second airflow inlet 141.

[0103] When the second container 30 is coupled to the first container 20, the first airflow outlet 242 and the lower end of the second channel CN2 can communicate. The first channel CN1 and the second channel CN2 can communicate to form a single flow path CN. The second channel CN2 can communicate with the second airflow outlet 354.

[0104] When a user places the mouthpiece 35 in their mouth and inhales air, external air can be supplied to the user by sequentially passing through the second airflow inlet 141, the first channel CN1, the second channel CN2, and the second airflow outlet 354. Aerosols can be generated in the first chamber C1, which is separated from the first channel CN1. Due to the inhalation force and pressure difference, the air passing through the first channel CN1 can flow together with the air and aerosols in the first chamber C1. The air and aerosols can flow into the first channel CN1 by passing through the first gap 227c and the second gap 227d between the supporters 227.

[0105] Therefore, by ensuring that air flows only to one side of the first chamber C1, the size of the flow path can be reduced, and the size of the aerosol generator can be reduced or optimized. In addition, the airflow resistance can be reduced from the structure supporting the core 25.

[0106] The airflow sealing section 268 can be in close contact with the lower part of the second container 30 around the lower end of the second channel CN2. The airflow sealing section 268 can surround the lower end of the second channel CN2 and the first airflow outlet 242. The airflow sealing section 268 can seal the space between the first container 20 and the second container 30 around the lower end of the airflow discharge channel 340 and the first airflow outlet 242.

[0107] Therefore, it is possible to prevent air passing through the airflow discharge channel 340 from the first airflow outlet 242 from leaking between the first container 20 and the second container 30, thereby improving the airflow efficiency.

[0108] Referring to Figure 17, the first airflow inlet 241' and the second airflow inlet 141' may be formed in different locations than in the embodiment of Figure 16. The first airflow inlet 241' may be formed on the side of the first chamber C1. The second airflow inlet 141' may be formed in the body 10 and may communicate with the first airflow inlet 241'. The second airflow inlet 141' may face the first airflow inlet 241'.

[0109] The first channel CN1' is formed in the first chamber C1 and may have a first airflow inlet 241' and a first airflow outlet 242 at both ends. The core 25 may be positioned between the first airflow inlet 241' and the first airflow outlet 242. The first channel CN1' can pass through the core 25. The first channel CN1' can communicate with the second channel CN2 to form a flow path CN' through which air flows.

[0110] The four second supporters 227b can support the four lower vertices of the first core part 251. The first gap 227c can be formed around the lower periphery of the first core part 251. The first channel CN1' can pass through the first gap 227c.

[0111] Air can be discharged by sequentially flowing through the second airflow inlet 141', the first channel CN1', the second channel CN2, and the second airflow outlet. The air may be accompanied by aerosols from the first chamber C1 as it passes through the first channel CN1'.

[0112] Therefore, the size of the flow path can be reduced, and the size of the aerosol generator can be reduced. In addition, the airflow resistance from the structure supporting the core 25 can be reduced.

[0113] Referring to Figures 18 and 19, the second container 30 can be detachably coupled to the upper side of the first container 20. The second container 30 can be coupled to the body 10 and indirectly coupled to the first container 20. The second container 30 can be coupled to the upper side of the first container 20 and exposed to the upper side of the body 10.

[0114] The aerosol generator may further include an upper case 36. The upper case 36 may have a hollow 364 opening on the lower side. The upper case 36 may be detachably coupled to the upper side of the body 10. A mouthpiece 35 may be coupled to the upper case 36. A second container 30 is inserted into the hollow 364 of the upper case 36, and the outer wall 361 of the upper case 36 may surround and cover the outside of the second container 30. A second airflow outlet 354 of the mouthpiece 35 may communicate with a first airflow outlet 342. The portion of the outer wall 361 of the upper case 36 corresponding to the second chamber C2 may be at least partially light-transmitting. The upper case 36 may have a window in the outer wall 361.

[0115] The second container 30 may be provided with an inclined wall 319. The inclined wall 319 may be formed such that one corner (or edge) of the second container 30 is tapered at an angle. The inclined wall 319 may be formed by chamfering one corner of the second container 30. The inclined wall 319 may be provided with a second chamber C2 (see Figure 22).

[0116] The inclined wall 319 may be positioned around the absorption section 316. The inclined wall 319 may be formed opposite the airflow discharge channel 340 relative to the absorption section 316. For example, the airflow discharge channel 340 may be formed to the left of the absorption section 316, and the inclined wall 319 may be formed to the right of the absorption section 316.

[0117] The cover 70 may be positioned around the first container 20. The cover 70 may be positioned horizontally away from the first container 20. For example, the first container 20 may be positioned on the left side and the cover 70 on the right side. The cover 70 may be positioned opposite the first airflow outlet 242 with respect to the core 25. For example, the first airflow outlet 242 may be formed on the left side of the core 25 and the cover 70 may be positioned on the right side of the core 25. The cover 70 may be positioned above the first container 20.

[0118] The cover 70 may be positioned in a location corresponding to the inclined wall 319. The cover 70 may be formed to slope (or incline) to the gradient (or inclination) corresponding to the inclined wall 319. The cover 70 may be positioned below the inclined wall 319. The inclined wall 319 may cover the cover 70. When the second container 30 is coupled to the first container 20, the inclined wall 319 may slide on the cover 70.

[0119] Referring to Figures 20 and 21, the containment space 84 can be separated from the first chamber C1 by a partition wall 222. The partition wall 222 can extend vertically between the first chamber C1 and the containment space 84. The first chamber C1 may be formed to the left of the partition wall 222, and the containment space 84 may be formed to the right of the partition wall 222. The containment space 84 and the partition wall 222 can extend above the first container 20. The containment space 84 can open upwards.

[0120] The light source 86 may be placed in the containment space 84. The light source 86 may face the opening of the containment space 84. The light source 86 may emit light in the direction it is facing. For example, the light source 86 may be an LED. The light source 86 may be mounted on a substrate 85. The substrate 85 may be directly or indirectly connected to the power supply 11 and / or the control unit 12. The substrate 85 may be tilted at an angle. The light source 86 may be tilted at an angle together with the substrate 85. The light source 86 may be tilted in a direction in which the inclined portion 319 forms an inclination. The light source 86 may emit light toward the second container 30.

[0121] The sensor 87 may be positioned around the light source 85. The sensor 87 may be installed on the substrate 85. The sensor 87 may be adjacent to the opening of the housing space 84. The sensor 87 may be a proximity sensor. The sensor 87 may detect changes in the surrounding electromagnetic field.

[0122] The cover 70 can cover the upper opening of the housing space 84. The cover 70 can cover the light source 86. The cover 70 may be made of a light-transmitting material. The cover 70 can transmit light emitted from the light source 86. The cover 70 can cover the sensor 86.

[0123] The cover 70 may include a first cover part 71 that is tilted at an angle, and a second cover part 72 that extends downward from the periphery of the first cover part 71. The first cover part 71 may be tilted in the direction in which the light source 86 is tilted. The second cover part 72 may form the periphery of the cover 70.

[0124] The second cover part 72 can be supported by a cover supporter 81 formed on the upper edge of the containment space 84. The cover supporter 81 may include a lower support portion 811 that projects inward from the edge of the containment space 84. The lower support portion 811 can support the lower end of the second cover part 72. The cover supporter 81 may include a side support portion 812 that projects upward from the lower support portion 811 and surrounds the upper part of the containment space 84. The side support portion 812 can support the side of the second cover part 72.

[0125] Referring to Figures 22 and 23, the lower wall 311 and side walls 321 and 322 forming the second chamber C2 can transmit light. The upper wall 33 of the second chamber C2 can transmit light. The portion of the outer wall 361 of the upper case 36 that covers the second chamber C2 can transmit light at least partially.

[0126] The inclined wall 319 may be formed between the lower wall 311 and the outer wall 321a of the second chamber C2. The inclined wall 319 may be formed to slope downward from the outer wall 321a toward the lower wall 311. The inclined wall 319 may cover the second chamber C2.

[0127] The second container 30 can be detachably coupled to the first container 20. The cover 70 may be positioned below the inclined wall 319. The cover 70 may be positioned between the inclined wall 319 and the light source 86. The cover 70 and the inclined wall 319 may have corresponding slopes. The cover 70 may face the inclined wall 319. The cover 70 may be in contact with the inclined wall 319.

[0128] The light source 86 can be adjacent to the cover 70 and the inclined wall 319. The light source 86 can be directed towards the cover 70 and the inclined wall 319. The light source 86 can be tilted in the direction in which the inclined wall 319 is tilted. Light emitted from the light source 86 can be transmitted through the cover 70 and the inclined wall 319 and supplied to the second chamber C2.

[0129] Therefore, the volume of liquid stored in the second chamber C2 can be easily confirmed with the naked eye. Furthermore, the volume of liquid stored in the second chamber C2 can be easily confirmed even in a dark environment.

[0130] Furthermore, the area within the second chamber C2 that receives light can be expanded, reducing the dark side where light is not supplied. In addition, the liquid storage capacity and structural space efficiency of the second chamber C2 can be improved compared to when the light source 86 is positioned on the side of the second chamber C2 and directed towards the second chamber C2.

[0131] When the second container 30 approaches the first container 20, the sensor 87 can detect an electromagnetic change. The sensor 87 can detect the electromagnetic change and transmit a signal to the control unit 12. Based on the signal received from the sensor 87, the control unit 12 can determine that the second container 30 is adjacent to or coupled with the first container 20.

[0132] Referring to Figure 24, the illumination range is shown depending on the tilt angle of the light source 86 with respect to the horizontal. The light source 86 can be tilted to a predetermined angle with respect to the horizontal toward the second chamber C2.

[0133] For example, the light source 86 is an LED and can have a light diffusion range of approximately 120 degrees. As an example, in Figures 24(a), (b), and (c), the light source 86 is tilted at 40 degrees, 30 degrees, and 20 degrees, respectively, with respect to the horizontal direction. In Figures 24(a), (b), and (c), dark areas Da1, Da2, Db1, Db2, and Dc1 can be formed on one and the other side of the second chamber C2. The size of the dark areas Da1, Da2, Db1, Db2, and Dc1 can vary depending on the arrangement angle of the light source 86. Compared to the case where the light source 86 is arranged vertically, the size of the dark areas can be reduced when the light source 86 is arranged at an angle.

[0134] Referring to Figure 25, the light source 88 is directed toward the reflector 88 and can supply light to the reflector 88. The reflector 88 can reflect the light transmitted from the light source 86 to the second chamber C2 back into the second chamber C2. The light that flows into the reflector 88 can be reflected toward the dark area.

[0135] The reflector 88 can be attached to the wall of the second chamber C2 and can face toward the second chamber C2. The inclined wall 319 can face toward the reflector 88. The reflector 88 can be attached to the wall of the second chamber C2 adjacent to the corner facing the inclined wall 319 relative to the second chamber C2. For example, the inclined wall 319 has a tapered corner between the lower wall 311 and the outer wall 321a of the second chamber C2, and the reflector 88 can be attached to at least a portion of the upper wall 33 and the inner wall 322 of the second chamber C2.

[0136] The first reflector 881 may be positioned on the inner wall 322 of the second chamber C2. The first reflector 881 can reflect light received from the light source 86 to the outer wall 321a of the second chamber C2 or to the second reflector 882. The second reflector 882 may be positioned on the upper wall 33 of the second chamber C2. The second reflector 882 can reflect light received from the light source 86 to the outer wall 321a of the second chamber C2 or to the first reflector 881.

[0137] The first reflector 881 can reflect the light reflected from the second reflector 882 to the outer wall 321a of the second chamber C2. The second reflector 882 can reflect the light reflected from the first reflector 881 to the first outer wall 321a of the second chamber C2.

[0138] Therefore, the reflector 88 can reduce or eliminate dark areas.

[0139] As another example, the light source 86 can be positioned below the second chamber C2 and directed perpendicularly upwards toward the second chamber C2. The inclined portion 319 can be eliminated. The reflector 88 can reduce or eliminate dark areas by reflecting the light received from the light source 86 off the outer wall 321a of the second chamber C2.

[0140] Referring to Figures 26 to 28, the cover 70 may include a light guide plate 73. The light guide plate 73 may be inclined to a slope corresponding to the inclined wall 319. The light guide plate 73 may face the inclined wall 319. The light guide plate 73 may form a first cover part 71 and a second cover part 72. The first cover part 71 may have a shape and size corresponding to the inclined wall 319. The light guide plate 73 may cover the light source 86. The light guide plate 73 may receive light from the light source 86 and distribute the light throughout the entire light guide plate 73. The light guide plate 73 may spread the light incident from the light source 86 widely.

[0141] The light source 86 can be in contact with or adjacent to one side of the light guide plate 73. For example, referring to Figure 27, the light source 86 can be adjacent to or in contact with the first cover part 71 of the light guide plate 73, and the light source 86 can supply light to the first cover part 71. For another example, referring to Figure 28, the light source 86 can be adjacent to or in contact with the second cover part 72 of the light guide plate 73, and the light source 86 can supply light to the second cover part 71. The light flowing from the light source 86 into the light guide plate 73 is totally reflected inside the light guide plate 73, and the light can be distributed throughout the entire light guide plate 73.

[0142] The cover 70 may include a diffuser 75. The diffuser 75 can be called a diffuser plate 75 or a diffuser sheet 75. The diffuser 75 can cover the light source 86. The diffuser 75 can diffuse the light emitted from the light source 86 into the second chamber C2. The diffuser 75 can prevent the light emitted from the light source 86 from being partially concentrated, thereby distributing the light more uniformly.

[0143] The diffuser 75 may be positioned above the light guide plate 73. One side of the diffuser 75 can closely cover one side of the light guide plate 73. The diffuser 75 can diffuse the light emitted from the light guide plate 73 into the second chamber C2. The diffuser 75 can prevent the light emitted from the light guide plate 73 from being partially concentrated, and can distribute the light more uniformly. The diffuser 75 can be tilted to an angle corresponding to the inclined wall 319. The diffuser 75 can come into contact with the inclined wall 319.

[0144] Referring to Figure 28, the light emitted from the light source 86 is uniformly distributed across the entire surface via the cover 70, allowing for surface emission toward the inclined wall 319 (see Figure 28).
