  • the non-combustible heating-type smoking device 1 in the present embodiment causes only the external heater 35 to operate at the heating start time at which heating with respect to the tobacco rod 11 is started and performs preheating (initial heating) of the tobacco rod 11.
  • the external heater 35 is disposed along the cavity side peripheral wall 32 positioned at the outer peripheral portion (side surface) of the receiving cavity 34 and thus can efficiently heat the outer peripheral portion of the tobacco rod 11 received in the receiving cavity 34. That is, it is possible to efficiently preheat, in particular, the outer peripheral portion of the tobacco rod 11 before heating of the tobacco rod 11 by the internal heater 36 is started at the time T1 (internal heating start time).
  • the preheating period can be set as a period from the heating start time (that is, start of preheating) to a point of time when an elapsed time since the heating start time reaches a predetermined set time or when the temperature of the external heater 35 reaches a predetermined set temperature.
  • the controller 4 may set the set temperature to control the external heater 35 at 300°C.
  • the tobacco rod 11 is heated by both the external heater 35 and the internal heater 36 during a period (hereinafter referred to as "simultaneous heating period") from the heating start time to a point of time when an elapsed time since the heating start time reaches a predetermined set time or when the temperature of the external heater 35 reaches a predetermined set temperature, that is, from the time T1 (internal heating start time) to the time T2 (external heating stop time).
  • the internal heater 36 is disposed to have the same axis as the center axis CL1 of the receiving cavity 34.
  • the heat of the internal heater 36 penetrating the tobacco rod 11 (the filling material 111) is transmitted radially from the center side toward the outer peripheral side of the tobacco rod 11.
  • an aerosol-source material for example, glycerin and the like
  • water (moisture) in the filling material 111 first evaporates with an increase in the article temperature.
  • the evaporation occurs at around the boiling point (100°C) of water. It is considered that, when the article temperature of the filling material 111 in the tobacco rod 11 is further increased, nicotine whose atmospheric boiling point is about 250°C next starts to be volatilized, and, when the article temperature is further increased, glycerin whose atmospheric boiling point is 290°C evaporates and sucked as aerosol.
  • the controller 4 controls the temperature of the external heater 35 to be higher than the temperature of the internal heater 36 during the simultaneous heating period (times T1 to T2). For example, during the simultaneous heating period, the controller 4 sets the set temperature of the external heater 35 to 300°C and the set temperature of the internal heater 36 to 250°C and control the external heater 35 and the internal heater 36.
  • the temperature of the outer peripheral portion of the tobacco rod 11 is increased rapidly and efficiently by the external heater 35 in contact with or close to the outer peripheral portion during the preheating period of the tobacco rod 11, and the temperature of the external heater 35 is controlled to be higher than the temperature of the internal heater 36 also during the subsequent simultaneous heating period.
  • the external heater 35 is positioned at the base end side (the side of the mouthpiece portion 12) of the tobacco rod 11 received in the receiving cavity 34. It is thus possible to intensively heat, in particular, the region on the base end side of the outer peripheral portion in the tobacco rod 11 by the external heater 35. This provides an advantage that it is possible to effectively suppress condensation of aerosol generated on the leading end side (upstream side) of the tobacco rod 11 from occurring on the base end side (downstream side) of the tobacco rod 11.
  • the external-heater width dimension which is the length of the external heater 35 extending in the direction of the center axis CL1 of the receiving cavity 34, is preferably at least a dimension more than or equal to one-third the tobacco rod 11. Consequently, it is possible to sufficiently preheat the outer peripheral portion of the tobacco rod 11 during the preheating period of the tobacco rod 11 before the start of heating by the internal heater 36.
  • the temperature of the tobacco rod 11 can be maintained at a temperature at which condensation of aerosol does not occur by only heating with the internal heater 36.
  • the controller 4 thus stops the operation of the external heater 35 at a point of time when the external heating stop time (time T2) is reached. At this time, the controller 4 stops the operation of the external heater 35 before the temperature of the internal heater 36 exceeds the temperature of the external heater 35.
  • the external heating stop time (time T2) at which the operation of the external heater 35 is stopped can be set as a point of time when an elapsed time since the heating start time (that is, start of preheating) reaches a predetermined set time or when the temperature of the external heater 35 reaches a predetermined set temperature.
  • various forms can be employed, and the operation of the external heater 35 may be stopped at a point of time when a certain period has elapsed since the temperature of the external heater 35 has reached a predetermined set temperature.
  • the tobacco rod 11 is heated by only the internal heater 36, and the temperature of the external heater 35 decreases naturally. Therefore, as illustrated in Fig. 8 , the temperature of the internal heater 36 exceeds the temperature of the external heater 35 at an intermediate point in a period (hereinafter referred to as "internal heating period") from the external heating stop time (time T2) to the heating stop time (time T3).
  • Heating efficiency in heating the tobacco rod 11 is excellent in the internal heater 36 disposed at a center portion, compared with the external heater 35 disposed on the outer peripheral side of the receiving cavity 34. It is thus possible to generate aerosol stably and continuously by heating the tobacco rod 11 with only the internal heater 36, in which heating efficiency is excellent, during a remaining smoking period in which conditions for suppressing easy condensation of aerosol are met due to the temperature of the entirety of the tobacco rod 11 being increased sufficiently during the simultaneous heating period.
  • the controller 4 may control power supply from the power source 5 to the internal heater 36 so as to increase the temperature of the internal heater 36 compared with the temperature before stopping of the operation of the external heater 35.

  • the target article temperature is, for example, 150°C. As illustrated in Fig. 10 to Fig.
  • the non-combustible heating-type smoking device 1 in the present embodiment includes the internal heater 36 that is disposed in the receiving cavity 34 and that heats the tobacco rod 11 from inside to thereby volatilize the aerosol-source material, and the external heater 35 that is disposed at the side peripheral portion of the receiving cavity 34 and that preheats the outer peripheral portion of the tobacco rod 11 at least during the preheating period of the tobacco rod 11 to thereby suppress condensation of aerosol generated during the operation of the internal heater 36. Consequently, the temperature of the outer peripheral portion of the tobacco rod 11, which has difficulty in receiving heat from the internal heater and has a likelihood of easily receiving an influence (heat radiation loss) of outdoor air, can be previously increased sufficiently during the preheating period by the external heater. It is thus possible to suppress occurrence of condensation of aerosol generated during the operation of the internal heater 36. Therefore, it is possible to sufficiently ensure the delivery amount of aerosol during smoking and possible to improve the smoke voluminous feel.
  • the external heater 35 is not disposed in the first region R1 including the base end 32c at which the cavity bottom portion 331 of the cavity side peripheral wall 32 (side peripheral portion) is provided and the third region R3 including the insertion port 38, and the external heater 35 is disposed in the second region R2 positioned closer than the first region R1 to the insertion port 38. It is thus possible to intensively heat, of the outer peripheral portion in the tobacco rod 11, in particular, the region on the base end side by the external heater 35. Consequently, the aerosol generated on the leading end side (upstream side) of the tobacco rod 11 can be effectively suppressed from condensing on the base end side (downstream side) of the tobacco rod 11.
  • the internal heater 36 in the present embodiment has a tapered shape whose diameter decreases from the base end portion 36a toward the leading end portion 36b, and therefore, the amount of heat radiation with respect to the tobacco rod 11 tends to be smaller at the leading end portion 36b of the internal heater 36 than that on the base end side.
  • the external heater 35 is not disposed in the third region R3 in the cavity side peripheral wall 32 (side peripheral portion). It is thus possible to suppress, for example, the filter segment positioned at the front end portion of the mouthpiece portion 12 from burning or melting due to the heat of the external heater 35 when the external heater 35 is operated.
  • the shape of the internal heater 36 is a truncated cone shape.
  • the internal heater 36 is enabled to easily penetrate the filling material 111 of the tobacco rod 11 inserted into the receiving cavity 34.
  • generated heat of the internal heater 36 is easily transmitted to the filling material 111, which can improve efficiency in heating of the filling material 111.
  • the internal heater 36 is caused to penetrate the filling material 111 of the tobacco rod 11 inserted into the receiving cavity 34 in the present embodiment, the internal heater 36 may be inserted into a recessed portion formed on an end surface of the filling material 111 on the leading end side (upstream side) in the tobacco rod 11.
  • the internal heater 36 may have a conic solid shape (cone or pyramid shape) or a frustum shape (truncated cone or pyramid shape) and have a shape tapered from the side of the cavity bottom portion 331 toward the side of the insertion port 38.
  • a cone shape instead of the truncated cone shape, a cone shape may be employed.
  • the internal heater 36 may have a columnar shape. In this case, a conical portion may be formed at the columnar part of the internal heater 36 on the leading end side thereof.
  • the internal heater 36 may have n-fold symmetry with respect to the center axis CL1 of the receiving cavity 34, and n may be a whole number more than or equal to 3.
  • the leading end portion 36b of the internal heater 36 in the heating device 3 is disposed at a position corresponding to the leading end (an end portion on the side of the insertion port 38) of the second region R2 in the cavity side peripheral wall 32 (side peripheral portion).
  • the position of the leading end portion 36b is, however, not limited thereto.
  • the leading end portion 36b of the internal heater 36 may be disposed at a position corresponding to an intermediate portion of the second region R2.
  • the leading end portion 36b of the internal heater 36 may be disposed at a position corresponding to the third region R3.
  • the leading end portion 36b of the internal heater 36 may be disposed at a position corresponding to the first region R1.
  • non-combustible heating-type smoking device according to the present invention is not limited thereto, and the embodiment 149+14and the modifications can be combined together as far as possible.
