Referring to FIGS. 20 and 21 , when the stick 400 passes through the insertion hole 304 , the cover 310 may be inserted into the cover groove 215 . The cover 310 may overlap the inner wall 212 of the first container 210 and form one side wall of the insertion space 214 together with the inner wall 212 of the first container 210.

Referring to FIGS. 21 and 22 , the stick 400 may slide along the surface of the cover 310 and be inserted into the insertion space 214 . The second guide 306 may be disposed at a position opposite the pivot axis of the cover 310, with the insertion hole 304 as the center. The second guide 306 may be disposed in a position opposite to the cover groove 215. When the stick 400 is inserted into the insertion space 214, the end of the stick 400 may contact the second guide 306. When the end of the stick 400 contacts the second guide 306, the second guide 306 may guide the stick 400 to the correct position in the insertion space 214.

The first guide 216 may be disposed in a position opposite to the second guide 306. The first guide 216 may be disposed lower than the second guide 216.

When the end of the stick 400 contacts the first guide 216, the first guide 216 may guide the stick 400 to the correct position in the insertion space 214.

When inserted into the insertion space 214, the end of the stick 400 may contact the stick stopper 217. The stick stopper 217 may contact the end of the stick 400 to restrict the stick 400 from moving to the lower side of the insertion space 214 or the second chamber C2.

Accordingly, when the user pushes the cover 310 through the stick 400, the position of the stick 400 is guided to an accurate position so that it can smoothly pass through the insertion hole 304, so that the cover 310 can be pushed out.

In addition, even if the stick 400 pushes the cover 310 and the cover 310 is placed inside the insertion space 214, the cover 310 is received in the cover groove 215, so that the stick 400 is inserted. It may be in close contact with the wall dividing the space 214.

In addition, since the stick 400 is in close contact with the wall dividing the insertion space 214, when the user inhales air through the stick 400, air is unnecessarily drawn between the insertion space 214 and the stick 400. It is possible to prevent the air flow efficiency from being reduced by preventing it from flowing and reducing wasted suction power.

In addition, even when the user pushes the cover 310 through the stick 400 and the cover 310 applies an external force to the end of the stick 400 in the second direction, the stick 400 remains in the insertion space 214. It can be guided to be inserted correctly.

Referring to FIG. 35, the aerosol generating device 1000 may monitor a signal from a motion sensor in operation S3510. For example, the aerosol generating device 1000 may monitor signals from an acceleration sensor and/or a gyro sensor.

The aerosol generating device 1000 may determine the direction in which the aerosol generating device 1000 is heading in operation S3520. For example, the aerosol generating device 1000 may determine the direction in which the aerosol generating device 1000 is heading in the Cartesian coordinate system based on the signal output from the acceleration sensor. Here, the direction in which the aerosol generating device 100 faces may mean the direction in which the top of the aerosol generating device 100, for example, the upper wall 303 of the cap 300, faces.

The aerosol generating device 1000 may determine whether a predetermined input is received from the user in operation S3530. At this time, the user can input a predetermined input using the movement of the aerosol generating device 1000. For example, the aerosol generating device 1000 may determine whether a tap input for tapping the aerosol generating device 1000 is received a preset number of times, based on signals from an acceleration sensor and/or a gyro sensor.

When a predetermined input is received from the user in operation S3540, the aerosol generating device 1000 may determine whether the direction toward which the aerosol generating device 1000 is heading is a preset direction. For example, the preset direction may be a direction in which the upper end of the aerosol generating device 1000 is directed upward and the lower end of the aerosol generating device 1000 is directed downward.

The aerosol generating device 1000 may radiate light through the light source 153 when the direction toward which the aerosol generating device 1000 faces is a preset direction in operation S3550.

36 and 37, with the top and bottom of the aerosol generating device 1000 facing upward and downward, respectively, the user taps the lower body 110 a preset number of times (e.g., 3 times). A predetermined input can be entered into the aerosol generating device 1000 through the tap input 3610.

Since the aerosol generating device 1000 receives a predetermined input while facing a preset direction, it can irradiate light through the light source 153. At this time, the light emitted from the light source 153 may be directed to the chamber C1 through the outside of the insertion space 214. Additionally, the light irradiated toward the chamber C1 may be emitted to the outside of the cap 300 through the chamber C1, the outer wall 211, and the cap body 310 in sequence.

Additionally, as light radiates outward through the outer wall 211 and the cap body 310, the interior 3710 of the first container 210 may be displayed to the outside.

Additionally, the user can accurately check the volume 3715 of liquid stored in the chamber C1 even in a dark environment.

Meanwhile, the aerosol generating device 1000 can change the color of light emitted through the light source 153. The aerosol generating device 1000 may determine the color of light emitted through the light source 153 according to the number of puffs the user takes. For example, the aerosol generating device 1000 displays white when the current number of puffs stored in the memory 1400 is less than the first number, blue when the number is greater than or equal to the first number and less than the second number, and blue when the number of puffs is greater than or equal to the first number. The color of the light can be determined as yellow if the number of puffs is less than the maximum, and red if the number of puffs is more than the maximum.

Since the aerosol generating device 1000 receives a predetermined input while facing a direction different from the preset direction, the aerosol generating device 1000 receives a predetermined tap input a preset number of times (e.g., 3 times), unrelated to the light source 153. The corresponding action can be performed.

For example, an operation corresponding to a predetermined input unrelated to the light source 153 may be an operation of updating data stored in the memory 1400. When a predetermined input is received while facing a direction different from the preset direction, the aerosol generating device 1000 selects a temperature profile corresponding to the predetermined input from among a plurality of temperature profiles stored in the memory 1400 as the temperature profile to be used. It can be updated with .

For example, an operation corresponding to a predetermined input unrelated to the light source 153 may be an operation to activate the lock mode. The aerosol generating device 1000 may block the supply of power to the heater 262 when a predetermined input is received while facing a direction different from the preset direction.

For example, an operation corresponding to a predetermined input unrelated to the light source 153 may be an operation to activate a function to release the lock mode. When a predetermined input is received while facing a direction different from a preset direction, the aerosol generating device 1000 may activate a function to release the lock mode and monitor a signal from a motion sensor. At this time, the aerosol generating device 1000 may check the direction in which the aerosol generating device 1000 is heading and/or the pattern of the number of times a tap input is received through a signal from the motion sensor. Additionally, the aerosol generating device 1000 may release the lock mode and supply power to the heater 262 when the confirmed pattern corresponds to a preset pattern.
