  • a heater can be disposed surrounding an outer surface of the elongated cavity (114) to heat the aerosol-generating article accommodated in the elongated cavity (114). In one embodiment, the heater can be disposed surrounding at least a portion of the outer surface of the elongated cavity (114).
  • the aerosol generating device (11) may further include general-purpose components in addition to the battery (111), control unit (112), vaporizer (113), and elongated cavity (114).
  • the aerosol generating device (11) may include a sensing unit, an output unit, a user input unit, a memory, and a communication unit.
  • the aerosol generating device (11) may include vaporizers (113) and elongated cavities (114) arranged in series or parallel.
  • the aerosol generated by the vaporizer (113) can flow into the elongated cavity (114) through the airflow passage in the aerosol generating device (11) and pass through the aerosol generating article (12). Accordingly, tobacco flavor or nicotine can be added to the aerosol that has passed through the aerosol generating article (12), and the user can inhale the aerosol added with tobacco flavor or nicotine by inhaling one end of the aerosol generating article (12) with the mouth.
  • a vaporizer (113) may include a liquid storage unit, a liquid delivery means, a heating element, and an airflow passage.
  • Each component of the vaporizer (113) may be made of a polycarbonate material, but is not limited thereto.
  • control unit (112) can control the temperature of the heating element by controlling the current supplied to the heating element. Accordingly, the control unit (112) can control the amount of aerosol generated from the liquid composition by controlling the current supplied to the heating element. In addition, the control unit (112) can control to supply current to the heating element for a preset period of time when the user's puff is detected. For example, the control unit (112) can control to supply current to the heating element for 1 to 5 seconds from the time the user's puff is detected.
  • control unit (112) can control the opening/closing state of the airflow passage to control the amount of aerosol emitted from the vaporizer (113). Specifically, the control unit (112) can increase the size of the gap in the airflow passage to increase the amount of aerosol emitted from the vaporizer (113), and can decrease the size of the gap in the airflow passage to decrease the amount of aerosol emitted from the vaporizer (113). For example, the control unit (112) can control the gap in the airflow passage using a dial method.
  • control unit (112) can notify the user of a shortage of liquid composition through a vibration motor or a display when the liquid composition in the liquid storage unit is less than a preset amount.
  • control unit (112) can control the temperature at which the heater heats the aerosol-generating article (12).
  • control unit (112) can regulate the temperature at which the heater heats the medium.
  • control unit (112) can control the heater between a non-heating mode and a low-temperature heating mode.
  • the heater may not heat the aerosol-generating article (12), and the medium portion may not be heated at this time.
  • the heater may low-temperature heat the aerosol-generating article (12) to a temperature of 0 degrees Celsius or higher and 150 degrees Celsius or lower.
  • the medium portion may be low-temperature heated to a temperature of 0 degrees Celsius or higher and 150 degrees Celsius or lower.
  • the taste intensity can be adjusted.
  • the amount of nicotine transferred from the medium portion is relatively low, so the taste intensity can be relatively low.
  • the amount of nicotine transferred from the medium portion is relatively high, so the taste intensity can be relatively high. Therefore, in the low-temperature heating mode, a sufficient taste intensity can be secured even without increasing the pH of the medium portion.
  • Example 2 As shown in Table 1 above, compared to Example 1 (control group) consisting of only a moisturizer, the composition of Example 2 with WS-3 added showed a slight increase in menthol migration amount, but the composition of Example 3 with menthol added showed a decrease in menthol migration amount. It is thought that when menthol is added alone, it has a detrimental effect on atomization due to compositional imbalance such as precipitation.
  • Example 4 which added both a moisturizer and WS-3 and menthol, showed a much higher menthol migration amount compared to the composition of Example 2, which added a moisturizer and WS-3, or Example 3, which added a moisturizer and menthol. It can be seen that the simultaneous addition of WS-3 and menthol has a synergistic effect in improving the menthol migration amount.
  • composition (No.) furtherance Menthol transfer amount (mg)
  • Example 5 WS-3 1.0 wt% + menthol 10 wt% 1.70
  • Example 6 WS-3 1.0 wt% + menthol 10 wt% + WS-23 1.0 wt% 3.89
  • Example 7 WS-3 1.0 wt% + menthol 10 wt% + WS 2.0 wt% 4.08
  • Example 8 WS-3 1.0 wt% + menthol 10 wt% + WS 3.0 wt% 4.18
