Aerosol generation device

Abstract

An aerosol generation device includes a storage chamber storing an aerosol source, a heating chamber configured to heat the aerosol source, and an accommodation portion accommodating a flavor source therein. The heating chamber accommodates at least a part of a holding portion configured to transport the aerosol source stored in the storage chamber to the heating chamber and hold the aerosol source in the heating chamber, and at least a part of a first load configured to heat the aerosol source held by the holding portion to vaporize and/or atomize the aerosol source. The aerosol source and the flavor source each contain menthol. The aerosol generation device further comprises an aerosol flow path connecting the heating chamber and the accommodation chamber, and configured to transport the aerosol source vaporized and/or atomized by the first load in the heating chamber to the accommodation chamber.

         4 . The aerosol generation device according to  claim 3 , wherein
 the aerosol flow path is formed such that a cross-sectional area at a second end portion connected to the accommodation chamber is larger than a cross-sectional area at a first end portion connected to the heating chamber, and increases in cross-sectional area from the first end portion toward the second end portion.   
     
     
         5 . The aerosol generation device according to  claim 4 , further comprising:
 a power supply; and   a controller configured to control discharge from the power supply to the first load and discharge from the power supply to the second load, wherein   the controller is configured to control,   during aerosol supply in which the aerosol source held by the holding portion is heated by the first load, and the vaporized and/or atomized aerosol source is aerosolized and supplied to the accommodation chamber,   the discharge from the power supply to the second load such that a temperature of the second load, a temperature of the accommodation chamber, or a temperature of the flavor source becomes a temperature lower than a temperature of the first load.   
     
     
         6 . The aerosol generation device according to  claim 5 , wherein
 the controller is configured to control, during the aerosol supply, the discharge from the power supply to the second load such that the temperature of the second load, the temperature of the accommodation chamber, or the temperature of the flavor source becomes a temperature higher than a melting point of the menthol and lower than a boiling point of the menthol.   
     
     
         7 . The aerosol generation device according to  claim 6 , wherein
 the controller is configured to control, during the aerosol supply, the discharge from the power supply to the first load such that the temperature of the first load is equal to or higher than the boiling point of the menthol.   
     
     
         8 . The aerosol generation device according to  claim 5 , wherein
 the controller is configured to control, during the aerosol supply, the discharge from the power supply to the second load such that the temperature of the second load, the temperature of the accommodation chamber, or the temperature of the flavor source is higher than the melting point of the menthol and is 90 [°C] or lower.   
     
     
         9 . The aerosol generation device according to  claim 1 , wherein
 the second load has an annular shape, and   at least a part of the accommodation chamber is accommodated in a hollow portion of the annular second load.   
     
     
         10 . The aerosol generation device according to  claim 1 , wherein
 the aerosol source vaporized and/or atomized by the first load is aerosolized in the heating chamber and the aerosol flow path to generate an aerosol, and   the accommodation chamber includes:
 an inlet portion for introducing the aerosol from the aerosol flow path into the accommodation chamber; and 
 an outlet portion for discharging the aerosol introduced into the accommodation chamber to an outside of the accommodation chamber, and 
   in a flow direction of the aerosol in the accommodation chamber in which the aerosol flows from the inlet portion to the outlet portion,   the accommodation chamber includes a first space in which the flavor source is present, and a second space located between the first space and the outlet portion, adjacent to the outlet portion, and in which the flavor source is not present.   
     
     
         11 . The aerosol generation device according to  claim 1 , wherein
 the aerosol source vaporized and/or atomized by the first load is aerosolized in the heating chamber and the aerosol flow path to generate an aerosol, and   the accommodation chamber includes:
 an inlet portion for introducing the aerosol from the aerosol flow path into the accommodation chamber; and 
 an outlet portion for discharging the aerosol introduced into the accommodation chamber to an outside of the accommodation chamber, and 
   in a flow direction of the aerosol in the accommodation chamber in which the aerosol flows from the inlet portion to the outlet portion,   the accommodation chamber includes a heating region in which the second load is disposed, and a non-heating region located between the heating region and the outlet portion, adjacent to the outlet portion, and in which the second load is not disposed.
