[0030] Terms including ordinal numbers such as first, second, etc. may be used to describe various components, but it should be understood that the components are not limited by the terms, and the terms are used only to distinguish one component from another.

[0031] When an element is said to be "connected" to another element, it will be understood that there can be other elements in between, whereas when an element is said to be "directly connected" to another element, it will be understood that there are no other elements in between.

[0032] The singular expression includes the plural expression unless the context clearly indicates otherwise.

[0033] 1, the aerosol generating device may include a body 10 and cartridges 20, 30. The cartridges 20, 30 may include a first container 20 and a second container 30. The cartridges 20, 30 may be coupled to the body 10.

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

[0035] The first container 20 may provide a first chamber C1 therein. The first container 20 may include a wick 25. The wick 25 may be disposed in the first chamber C1. An upper end of the wick 25 may protrude from the first chamber C1 to the upper side of the first container 20.

[0036] The first container 20 may include a heater 2531. The heater 2531 may be disposed in the first chamber C1. The heater 2531 may heat the wick 25. The heater 2531 may be attached to the wick 25. The first container 20 may include a terminal 223 therein. The terminal 223 may be exposed to a lower side of the first container 20. The terminal 223 may be electrically connected to the heater 2531. The first container 20 may be referred to as a lower container 20 or a heating module 20.

[0037] The first container 20 may include a first air inlet 241 formed by opening the first chamber C1. The first container 20 may include a first air outlet 242 formed by opening the first chamber C1.

[0038] The second container 30 may provide a second chamber C2 therein. The second container 30 may store liquid in the second chamber C2. The second container 30 may include an airflow discharge passage 340. Both ends 341, 342 of the airflow discharge passage 340 may be open. The airflow discharge passage 340 may be partitioned from the second chamber C2. The second container 30 may be referred to as an upper container 30 or a liquid storage unit 30.

[0039] The mouthpiece 35 may be coupled to the upper side of the second container 30. The mouthpiece 35 may cover the upper part of the second container 30. The mouthpiece 35 may have a second airflow outlet 354 therein. The second airflow outlet 354 may be connected to the other end 342 of the airflow exhaust passage 340. The mouthpiece 35 may be tilted via the shaft to open and close the airflow exhaust passage 340.

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

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

[0042] When the second container 30 is coupled to the first container 20, the second container 30 can supply a stored liquid to the wick 25. The wick 25 can receive and absorb 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] The body 10 may have an opening at one side to form a second airflow inlet 141. When the first container 20 is coupled to the body 10, the first airflow inlet 241 may 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 passage 340 may communicate with the first airflow outlet 242. Thus, a passage through which air flows may be formed. A user may inhale air by holding the mouthpiece 35 in his / her mouth. When the user inhales air, the outside air may be provided 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 passage 340, and the second airflow outlet 354. The air may 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 proper replacement cycle of the first container 20 are different from each other, so the user can replace only the second container 30 separately, or replace 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 proper replacement cycle of the first container 20, so that when the second container 30 is replaced several times, the first container 20 may be replaced only once. Therefore, the first container 20 can be used for a longer period of time, and the cost of replacing cartridges can be reduced.

[0045] 2, the first container 20 may be detachably coupled to the body 10. The first coupler 151 may detachably couple the first container 20 to the body 10.

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

[0079] Therefore, the aerosol generated by the wick 25 and the air around it can smoothly flow through the periphery of the plurality of supporters 227 toward the first airflow outlet 242 .

[0080] The first wick sealing portion 265 may be disposed between the circumferential surface 2522 of the second wick part 252 and the circumferential surface 235a of the liquid inlet 235. The inner circumferential surface of the first wick sealing portion 265 may be in intimate contact with the circumferential surface 2522 of the second wick part 252. The first wick sealing portion 265 may provide a seal between the circumferential surface 2522 of the second wick part 252 and the circumferential surface 235a of the liquid inlet 235.

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

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

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

[0084] 10 to 12, the second container 30 may provide a second chamber C2 for storing liquid. The second chamber C2 may be defined by a lower wall 311, side walls 321 and 322, and an upper wall 33 of the second container 30. The side walls 321 and 322 may extend vertically. The side walls 321 and 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 may be formed between the second chamber C2 and the airflow discharge passage 340, and may separate the second chamber C2 and the airflow discharge passage 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 in the lower part of the second chamber C2. The liquid outlet 314 may be composed of a plurality of holes. The liquid stored in the second chamber C2 may be discharged through the liquid outlet 314.

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

[0087] The absorbent part 316 can close the lower part of the liquid outlet 314. The absorbent part 316 can absorb the liquid that has passed through the liquid outlet 314. For example, the absorbent part 316 can be formed of a felt material.

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

[0089] The film 316a may be detachably attached to the lower surface of the absorbent part 316. An edge of the film 316a may be attached to the lower surface of the bracket 317. The film 316a may be made of a waterproof material. The film 316a may prevent liquid from leaking from the absorbent part 316. Before combining the second container 30 with the first container 20, a user may remove the film 316a from the absorbent part 316.

[0090] The recess 315 may be formed by recessing the lower surface 312 of the second container 30 upward. The groove formed by the recess 315 may surround the periphery of the bracket 317.

[0091] The second container 30 may have one configuration of the second coupler 152 (see FIGS. 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. As another example, the hook 135 may be formed by a protrusion in the outer wall 321 of the second container 30. As another example, the second container 30 may include a magnet or a ferromagnetic material.

[0092] The second container 30 may have an airflow exhaust passage 340. The airflow exhaust passage 340 may be partitioned from the second chamber C2 by the inner wall 322 of the second container 30. The airflow exhaust passage 340 may be defined by the outer wall 321 and the inner wall 322 of the second container 30. Both ends of the airflow exhaust passage 340 may be open. One end of the airflow exhaust passage 340 may be open to the lower side. The other end of the airflow exhaust passage 340 may be open to the upper side. One end of the airflow exhaust passage 340 may be formed by opening the lower surface 312 of the second container 30. The other end of the airflow exhaust passage 340 may be connected to a second airflow exhaust port 354 formed inside the mouthpiece 35. The airflow exhaust passage 340 may be referred to as a second channel CN2.

[0093] 13 and 14, the first container 20 may be detachably coupled to the body 10. A first coupler 151 may detachably couple the first container 20 and the body 10. The second container 30 may be detachably coupled to the first container 20. The second container 30 may be indirectly coupled to the first container 20 by being coupled to the body 10 via a second coupler 152. The second container 30 may be coupled to the upper side of the first container 20.

[0094] When the second container 30 is combined 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 by the absorbing part 316, and the absorbing part 316 that has absorbed the liquid can contact the second wick part 252 and transfer the liquid. The liquid absorbed by the second wick part 252 can diffuse into the first wick part 251. The heater 3531 can heat the first wick part 251 that has absorbed the liquid to generate an aerosol.

[0095] The sealer 26 can seal the periphery of the liquid inlet 235 through which the wick 25 is exposed from the first chamber C1. When the second container 30 is coupled to the top side 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, 267 may protrude toward the second container 30. The sealing walls 266, 267 may be in close contact with the second container 30. The sealing walls 266, 267 may surround the periphery of 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] 15, the first sealing wall 266 may surround the liquid inlet 235 and the periphery 2522 of the second wick part 252. The first sealing wall 266 may be in close contact with the lower part of the second container 30. The first sealing wall 266 may be in close contact with a protruding portion formed on the inner side of the recessed portion 266. For example, the first sealing wall 266 may be in close contact with the bracket 317. The bracket 317 and the first sealing wall 266 may surround the periphery 2522 of the second wick part 252. Therefore, the bracket 317 may not only fix the absorbing part 316, but also press the first sealing wall 266 to seal the periphery of the second wick part 252 and the liquid inlet 235.

[0099] The second sealing wall 267 may protrude higher than the first sealing wall 266. The second sealing wall 267 may be disposed horizontally outside the first sealing wall 266 and may surround the periphery of the first sealing wall 266. The second sealing wall 267 may be closely attached to the lower part of the second container 30. The second sealing wall 267 may be inserted into a groove formed by the recessed portion 315 and closely attached to the recessed portion 315.

[0100] Therefore, the first sealing wall 266 can seal the periphery of the second wick part 252 and the liquid inlet 235. Even if the liquid flows beyond the first sealing wall 266, it can be sealed by the second sealing wall 267.

[0101] 15 and 16, the first channel CN1 may be formed on the left side of the first chamber C1. The wick 25 and the heater 2531 may be disposed 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 wick 25 based on the vertical direction. The wick 25 may be spaced apart between the first airflow inlet 241 and the second airflow inlet 242. Unlike the illustrated example, at least one of the first airflow inlet 241 and the first airflow outlet 242 may be formed by opening a sidewall of the first container 20 at the first channel CN1.

[0102] When the first container 20 is coupled to the body 10, the second air inlet 141 formed by opening one side of the body 10 may communicate with the first air inlet 241. A gap between the body 10 and the first container 20 may be sealed around the second air inlet 141. For example, a hook 125 may seal between the body 10 and the first container 20 around the second air 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 with each other. The first channel CN1 and the second channel CN2 can communicate with each other to form a single flow path CN. The second channel CN2 can communicate with the second airflow outlet 354.

[0104] When a user holds the mouthpiece 35 in his mouth and inhales air, the outside air passes through the second air inlet 141, the first channel CN1, the second channel CN2, and the second air outlet 354 in sequence and is provided to the user. Aerosol may be generated in the first chamber C1 separated from the first channel CN1. The air passing through the first channel CN1 may flow together with the air and aerosol in the first chamber C1 due to the suction force and pressure difference. The air and aerosol may flow into the first channel CN1 through the first gap 227c and the second gap 227d between the supporters 227.

[0105] Therefore, by allowing air to flow only to one side of the first chamber C1, the size of the flow passage can be reduced, and the size of the aerosol generating device can be reduced or optimized. Also, air flow resistance from the structure supporting the wick 25 can be reduced.

[0106] The airflow sealing part 268 may 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 part 268 may surround the lower end of the second channel CN2 and the periphery of the first airflow exhaust port 242. The airflow sealing part 268 may seal between the first container 20 and the second container 30 around the lower end of the airflow exhaust passage 340 and the periphery of the first airflow exhaust port 242.

[0107] Therefore, the air passing through the air discharge passage 340 from the first airflow outlet 242 is prevented from leaking between the first container 20 and the second container 30, and the air flow efficiency can be improved.

[0108] 17, the first airflow inlet 241' and the second airflow inlet 141' may be formed at different positions from those in the embodiment of FIG 16. The first airflow inlet 241' may be formed at a 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' may be formed in the first chamber C1 and may have a first airflow inlet 241' and a first airflow outlet 242 at either end. The wick 25 may be disposed between the first airflow inlet 241' and the first airflow outlet 242. The first channel CN1' may pass through the wick 25. The first channel CN1' may communicate with the second channel CN2 to form a flow path CN' through which air flows.

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

[0111] The air may flow through the second airflow inlet 141', the first channel CN1', the second channel CN2, and the second airflow outlet in sequence, and may be discharged. The air may be accompanied by the aerosol in the first chamber C1 as it passes through the first channel CN1'.

[0112] This allows for a reduction in the size of the flow passage and therefore a reduction in the size of the aerosol generating device, and also reduces the air flow resistance from the structure supporting the wick 25.

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

[0114] The aerosol generating device may further include an upper case 36. The upper case 36 may have a hollow 364 that is open to the lower side. The upper case 36 may be detachably coupled to the upper side of the body 10. The mouthpiece 35 may be coupled to the upper case 36. The second container 30 may be inserted into the hollow 364 of the upper case 36, and an outer wall 361 of the upper case 36 may surround and cover the outside of the second container 30. The second airflow outlet 354 of the mouthpiece 35 may be in communication with the first airflow outlet 342. A portion of the outer wall 361 of the upper case 36 that corresponds 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 include a sloping wall 319. The sloping wall 319 may be formed such that one corner (or edge) of the second container 30 is obliquely tapered. The sloping wall 319 may be formed by chamfering one corner of the second container 30. The sloping wall 319 may include a second chamber C2 (see FIG. 22).

[0116] The inclined wall 319 may be disposed around the periphery of the absorption unit 316. The inclined wall 319 may be formed at a position facing the airflow discharge channel 340 with respect to the absorption unit 316. For example, the airflow discharge channel 340 may be formed on the left side of the absorption unit 316, and the inclined wall 319 may be formed on the right side of the absorption unit 316.

[0117] The cover 70 may be disposed around the periphery of the first container 20. The cover 70 may be horizontally spaced apart from the first container 20. For example, the first container 20 may be disposed on the left side and the cover 70 on the right side. The cover 70 may be disposed in a position opposite the first airflow outlet 242 with respect to the wick 25. For example, the first airflow outlet 242 may be formed on the left side of the wick 25 and the cover 70 may be disposed on the right side of the wick 25. The cover 70 may be disposed above the first container 20.

[0118] The cover 70 may be disposed at a position corresponding to the inclined wall 319. The cover 70 may be formed to be inclined at a gradient (or inclination) corresponding to the inclined wall 319. The cover 70 may be disposed 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 over the cover 70.

[0119] 20 and 21, the accommodating space 84 may be partitioned from the first chamber C1 by a partition 222. The partition 222 may extend vertically between the first chamber C1 and the accommodating space 84. The first chamber C1 may be formed on the left side of the partition 222, and the accommodating space 84 may be formed on the right side of the partition 222. The accommodating space 84 and the partition 222 may extend upward beyond the first container 20. The accommodating space 84 may be open upward.

[0120] The light source 86 may be disposed in the receiving space 84. The light source 86 may face the opening of the receiving space 84. The light source 86 may emit light in the direction in which the light source faces. 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 source 11 and / or the control unit 12. The substrate 85 may be inclined obliquely. The light source 86 may be inclined obliquely together with the substrate 85. The light source 86 may be inclined in a direction in which the inclined portion 319 forms a slope. The light source 86 may emit light toward the second container 30.

[0121] The sensor 87 may be disposed around the light source 85. The sensor 87 may be mounted on the substrate 85. The sensor 87 may be adjacent to an opening of the receiving space 84. The sensor 87 may be a proximity sensor. The sensor 87 may detect electromagnetic changes in the surroundings.

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

[0123] The cover 70 may include a first cover part 71 that is inclined obliquely, 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 inclined in the direction in which the light source 86 is inclined. The second cover part 72 may form the periphery of the cover 70.

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

[0125] 22 and 23, the bottom wall 311 and side walls 321, 322 forming the second chamber C2 are light-transmitting. The top wall 33 of the second chamber C2 is light-transmitting. A portion of the outer wall 361 of the upper case 36 covering the second chamber C2 is at least partially light-transmitting.

[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 may be detachably coupled to the first container 20. The cover 70 may be disposed under the inclined wall 319. The cover 70 may be disposed 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 contact the inclined wall 319.

[0128] The light source 86 may be adjacent to the cover 70 and the inclined wall 319. The light source 86 may face the cover 70 and the inclined wall 319. The light source 86 may be tilted in the inclined direction of the inclined wall 319. Light emitted from the light source 86 may be provided to the second chamber C2 through the cover 70 and the inclined wall 319.

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

[0130] In addition, the area where light is provided inside the second chamber C2 can be expanded, and the dark side where light is not provided can be reduced. Also, the liquid storage capacity and structural space efficiency of the second chamber C2 can be improved compared to the case where the light source 86 is arranged toward the second chamber C2 from the side of the second chamber C2.

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

[0132] 24 shows the irradiation range depending on the inclination angle of the light source 86 with respect to the horizontal direction. The light source 86 can be inclined at a predetermined angle with respect to the horizontal direction toward the second chamber C2.

[0133] For example, the light source 86 may be an LED and have a light diffusion range of about 120 degrees. For example, in the cases of (a), (b), and (c) of FIG. 24, the light source 86 has an inclination of 40 degrees, 30 degrees, and 20 degrees with respect to the horizontal direction, respectively. In the cases of (a), (b), and (c) of FIG. 24, dark areas Da1, Da2, Db1, Db2, and Dc1 may be formed on one side and the other side of the second chamber C2. The size of the dark areas Da1, Da2, Db1, Db2, and Dc1 may 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 may be reduced when the light source 86 is arranged at an angle.

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

[0135] The reflector 88 may be attached to a wall of the second chamber C2 and may face the second chamber C2. The inclined wall 319 may face the reflector 88. The reflector 88 may be attached to a wall of the second chamber C2 adjacent to a corner opposite the inclined wall 319 with respect to the second chamber C2. For example, the inclined wall 319 may be tapered at a corner between the bottom wall 311 and the outer wall 321a of the second chamber C2, and the reflector 88 may be attached to at least a portion of the top wall 33 and the inner wall 322 of the second chamber C2.

[0136] The first reflector 881 may be disposed on the inner wall 322 of the second chamber C2. The first reflector 881 may reflect light received from the light source 86 to the outer wall 321a of the second chamber C2 or the second reflector 882. The second reflector 882 may be disposed on the upper wall 33 of the second chamber C2. The second reflector 882 may reflect light received from the light source 86 to the outer wall 321a of the second chamber C2 or 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] Thus, the reflector 88 can reduce or eliminate the dark areas.

[0139] As another example, the light source 86 may be disposed below the second chamber C2 and may face the second chamber C2 vertically upward. The inclined portion 319 may be eliminated. The reflector 88 may reflect the light received from the light source 86 to the outer wall 321a of the second chamber C2 to reduce or eliminate the dark portion.

[0140] 26 to 28, the cover 70 may include a light guide plate 73. The light guide plate 73 may be inclined at an inclination 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 a 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 light guide plate 73. The light guide plate 73 may widely spread the light incident from the light source 86.

[0141] The light source 86 may be in contact with or adjacent to one side of the light guide plate 73. As an example, referring to Fig. 27, the light source 86 may be in contact with or adjacent to the first cover part 71 of the light guide plate 73, and the light source 86 may provide light to the first cover part 71. As another example, referring to Fig. 28, the light source 86 may be in contact with or adjacent to the second cover part 72 of the light guide plate 73, and the light source 86 may provide light to the second cover part 71. The light entering the light guide plate 73 from the light source 86 may be totally reflected inside the light guide plate 73, and the light may be distributed throughout the light guide plate 73.

[0142] The cover 70 may include a diffuser 75. The diffuser 75 may be referred to as a diffusion plate 75 or a diffusion sheet 75. The diffuser 75 may cover the light source 86. The diffuser 75 may diffuse the light emitted from the light source 86 into the second chamber C2. The diffuser 75 may prevent the light emitted from the light source 86 from being concentrated in a certain area, and may distribute the light more uniformly.

[0143] The diffuser 75 may be disposed above the light guide plate 73. One surface of the diffuser 75 may be in close contact with and cover one surface of the light guide plate 73. The diffuser 75 may diffuse the light emitted from the light guide plate 73 into the second chamber C2. The diffuser 75 may prevent the light emitted from the light guide plate 73 from being partially concentrated, and may distribute the light more uniformly. The diffuser 75 may be inclined at an inclination angle corresponding to the inclined wall 319. The diffuser 75 may be in contact with the inclined wall 319.

[0144] 28, the light emitted from the light source 86 can be uniformly distributed over the entire surface through the cover 70 and emitted toward the inclined wall 319 (see FIG. 28).
