  • Publication number: 20200085098
    Abstract: A flavor source unit includes a columnar lump body formed of a plurality of flavor pieces and a cylindrical body containing the columnar lump body. The cylindrical body includes a first cylindrical body end face that forms an air inflow end, a second cylindrical body end face that forms an air outflow end, and a cylindrical body side wall connecting an outer periphery of the first cylindrical body end face and an outer periphery of the second cylindrical body end face. The columnar lump body includes a first lump body end face that forms an air inflow end, a second lump body end face that forms an air outflow end, and a lump body side face that continues into an outer periphery of the first lump body end face and an outer periphery of the second lump body end face. The columnar lump body is disposed in such a way as to block an inside space of the cylindrical body side wall by the lump body side face contacting any portion of an inner surface of the cylindrical body side wall.

  • Patent number: 10172390
    Abstract: A non-combustion-type flavor inhaler includes a shape extending from a non-mouthpiece end to a mouthpiece end in a predetermined direction. The non-combustion-type flavor inhaler includes: an aerosol source generating aerosol; an atomizer atomizing the aerosol source without combustion; a power source supplying electric power to the atomizer; and a controller controlling an electric energy supplied from the power source to the atomizer. The controller randomly controls the electric energy supplied to the atomizer.

  • Patent number: 9808032
    Abstract: A non-burning type flavor inhaler includes: an aerosol source that generates an aerosol; an atomizer that atomizes the aerosol source without burning; a power source that supplies power to the atomizer; and a control unit that controls a power amount supplied from the power source to the atomizer. The control unit increases the power amount supplied to the atomizer stepwise from a reference power amount along with an increase in the number of puff actions for inhaling the aerosol.

  • Patent number: 9730473
    Abstract: A non-burning type flavor inhaler includes a main body unit having the non-inhalation end; and a capsule unit configured to be attachable/detachable to/from the main body unit. The main body unit includes an aerosol source, an atomizer, and a power source. The capsule unit includes a solid flavor source, and a filter adjacent to the inhalation end side with respect to the flavor source. A part of an outer surface of the flavor source except a portion adjacent to the filter is covered with a predetermined film composed of an impermeable member. The main body unit is provided with a breaker for breaking the part of the predetermined film in a part adjacent to the capsule unit.
