  • the reservoir 116 may have a construction which allows replenishment of a consumed aerosol source.
  • the reservoir 116 may be constructed in such a manner that the reservoir 116 itself is allowed to be replaced when the aerosol source is exhausted.
  • the aerosol source is not limited to that in a liquid form, and it may be solid. In the case that the aerosol source is solid, the reservoir 116 may be a hollow container which does not use fibrous or porous material, for example.
  • the atomizer 118 is constructed to generate aerosol from an aerosol source. Specifically, the atomizer 118 generates aerosol by atomizing or vaporizing an aerosol source. In the case that the inhaler 100 is a medical inhaler such as a nebulizer or the like, the atomizer 118 generates aerosol by atomizing or vaporizing an aerosol source including a medicine. When a puff action is detected by the sensor 70, the atomizer 118 generates aerosol by receiving supply of electric power from the electric power source part 20. For example, a wick (not shown in the figure) may be installed for connection between the reservoir 116 and the atomizer 118.
  • a part of the wick extends to the inside of the reservoir 116 and is in contact with the aerosol source.
  • the other part of the wick extends toward the atomizer 118.
  • the aerosol source is sent from the reservoir 116 to the atomizer 118 by capillary effect in the wick.
  • the atomizer 118 comprises a heater which is electrically connected to the electric power source part 20. The heater is arranged to be in contact with or to be positioned close to the wick.
  • the controller 50 controls the heater in the atomizer 118 to heat an aerosol source, which is conveyed via the wick, to thereby atomize the aerosol source.
  • the other example of the atomizer 118 may be an ultrasonic-type atomizer which atomizes an aerosol source by ultrasonic vibration.
  • a vent for taking air for making the air flow into the inside of the reservoir 116 is formed therein. Further, the air taking-in flow path 120 connected to the vent is connected to the atomizer 118, and leads to the outside of the inhaler 100. The aerosol generated in the atomizer 118 is mixed with air that is taken via the air taking-in flow path 120. The fluid mixture comprising the aerosol and the air is sent to the aerosol flow path 121, as shown by an arrow 124.
  • the aerosol flow path 121 has a tubular structure, which extends through the second member 104 and the third member 126, for sending the fluid mixture comprising the air and the aerosol, that is generated in the atomizer 118, to the puff opening part 122 in the third member 126.
  • the flavor source holder 128 is a component for adding flavor to aerosol.
  • the flavor source holder 128 is positioned in the middle of the aerosol flow path 121.
  • the fluid mixture comprising the air and the aerosol generated by the atomizer 118 (the fluid mixture may simply be referred to as aerosol, hereinafter) flows to the puff opening part 122 through the aerosol flow path 121.
  • the flavor source holder 128 is arranged in a position downstream the atomizer 118.
  • the position of the flavor source holder 128 is closer to the puff opening part 122 than the position of the atomizer 118.
  • the aerosol generated in the atomizer 118 passes through the flavor source holder 128 and thereafter arrives at the puff opening part 122.
  • fragrance-inhaling-taste components included in the flavor source holder 128 are added to the aerosol.
  • the flavor source holder 128 may be that which originates from tobacco, such as shredded tobacco, a product which is made by processing tobacco raw material to have a granular form, a sheet form, or a powder form, or the like. Further, flavor source holder 128 may be that which does not originate from tobacco, such as a product made by use of a plant other than tobacco (for example, mint, a herb, and so on). For example, flavor source holder 128 comprises a nicotine component. The flavor source holder 128 may comprise a flavor component such as menthol or the like.
  • the reservoir 116 may also have a material comprising a fragrance-inhaling-taste component.
  • the inhaler 100 may be constructed in such a manner that the flavor source holder 128 holds flavor material which originates from tobacco and the reservoir 116 includes flavor material which does not originate from tobacco.
  • the controller 50 performs judgment based on whether the respective values of the total number of times of supply of electric power and the number of times of normal supply of electric power coincide with each other, and, in the case that the values do not coincide with each other, judges that the state of the electric power source part 20 is "electric-power-source abnormality.”
  • the controller 50 performs judgment based on whether the respective values of the total number of times of supply of electric power and the number of times of normal supply of electric power coincide with each other, and, in the case that the values do not coincide with each other, judges that the state of the electric power source part 20 is "electric-power-source abnormality."
  • the controller 50 performs judgment based on whether the respective values of the total number of times of supply of electric power and the number of times of normal supply of electric power coincide with each other, and, in the case that the values do not coincide with each other, judges that the state of the electric power source part 20 is "electric-power-source abnormality."
  • the number of times of normal supply of electric power is not counted, in the case that
  • the controller 50 judges the state of the electric power source part 20 in a manner similar to that in the flow shown in each of modification examples in Fig. 7 and Fig. 8 shown in relation to the first embodiment.
  • the controller 50 judges whether a difference (the number of times of non-counted cases) between the total number of times of supply of electric power and the number of times of normal supply of electric power has reached a predetermined threshold number of times. That is, in the case that the number of times of normal supply of electric power was not counted plural times, as a result that the voltage Vbatt of the electric power source part 20 has become a value less than a voltage threshold value, and, thus, the number of times of non-counted cases has reached a predetermined threshold number of times, the state of the electric power source part 20 is judged as "electric-power-source abnormality.”
  • the controller 50 associates the total number of times of supply of electric power and the number of times of normal supply of electric power with each other and stores them in the memory 80. Thereafter, the controller 50 judges whether a difference (the number of times of non-counted cases occurred consecutively) between the total number of times of supply of electric power and the number of times of normal supply of electric power has reached a predetermined threshold number of times, as a result that the number of times of normal supply of electric power was not counted plural times consecutively.
  • the state of the electric power source part 20 is judged as "electric-power-source abnormality.”
  • the matter that the number of times of normal supply of electric power is not "consecutively" measured corresponds to the matter that an event that the voltage Vbatt of the electric power source part 20 becomes that lower than a voltage threshold value occurs during certain electric power supplying operation and the above event also occurs during next electric power supplying operation following the above certain electric power supplying operation.
  • the above electric power supplying operation is operation for supplying electric power from the electric power source part 20 to the heater 40, that is performed as a result that a user performs a series of puff actions, during a period from a start to an end of the series of puff actions.
  • the controller 50 in the electric power source unit is made to be able to further precisely judge the abnormal state of the electric power source part in a battery discharge period.
