  • the curve from the third channel 83 to the second channel 82 and the curve from the second channel 82 to the first channel 81 increase resistance of the intake channel, so that even if the aerosol flows backward from the atomization chamber toward the inlet 120IN, the aerosol flowing backward through the intake channel is decreased in temperature due to pressure loss.
  • the heater assembly 30 includes a cylindrical member provided along the outer lateral face of the columnar member 110 at a position adjacent to the second channel 82.
  • Figs. 13 to 15 are views for explaining a cylindrical member 90 according to Modification Example 1.
  • Fig. 13 is a cross-section of the heater assembly 30.
  • Figs. 14 and 15 are perspective views of the container 40.
  • Figs. 14 and 15 show the cylindrical member 90 as well as the container 40.
  • the heater assembly 30 includes the cylindrical member 90.
  • the cylindrical member 90 may comprise a heat conductive member (for example, metal such as SUS (steel use stainless)).
  • the cylindrical member 90 may comprise the same member as the container 40.
  • the cylindrical member 90 is provided at a position adjacent to the second channel 82.
  • the cylindrical member 90 is provided along the outer lateral face of the columnar member 110. In other words, the cylindrical member 90 has an inner lateral face that partitions off the fifth channel 85.
  • the container 40 includes a tapered portion 43 that outwardly spreads toward the second end 40B.
  • the tapered portion 43 is provided continuously to the holding portion 42A but not to the separated portion 42B in the predetermined direction X.
  • the tapered portion 43 holds the cylindrical member 90 so that the inner lateral face of the cylindrical member 90 is aligned with an inner lateral face of the holding portion 42A. Accordingly, the cylindrical member 90 contacts the container 40 at the tapered portion 43.
  • the cylindrical member 90 is located away from the separated portion 42B for the necessity of bringing the second and third channels 82 and 83 into communication.
  • a gap is provided between the cylindrical member 90 and the separated portion 42B.
  • the cylindrical member 90 may include a portion overlapping the container 40 in the intersecting direction Y.
  • the cylindrical member 90 may include a portion overlapping part of the tapered portion 43 or a portion overlapping the separated portion 42B.
  • Fig. 16 shows the second channel 82 according to Modification Example 1.
  • Fig. 16 is a cross-section along a line D-D in Fig. 13 .
  • the second channel 82 is a channel connecting the first channel 81 and the third channel 83.
  • the second channel 82 is a channel extending from the first channel 81 along the intersecting direction Y intersecting with the predetermined direction X as viewed in a section (see Fig. 13 , for example) of the heater assembly 30 along the predetermined direction X.
  • At least part of the second channel 82 is formed by the outer lateral face of the cylindrical member 90.
  • the second channel 82 is formed between the inner lateral face of the wall body 34 of the collar member 31 and the outer lateral face of the cylindrical member 90.
  • the second channel 82 may be formed between the inner lateral face of the holding portion 42A of the container 40 and the outer lateral face of the cylindrical member 90.
  • the second channel 82 has a shape extending along the outer periphery of the aerosol channel (namely, the cylindrical member 90).
  • the second channel 82 includes the channel 82 1 extending in the first direction along the inner periphery of the aerosol channel and the channel 82 2 extending along the inner periphery of the aerosol channel in the second direction that is opposite to the first direction.
  • Fig. 17 is a view for explaining the leakage of the aerosol according to Modification Example 1.
  • Fig. 17 is a perspective cross-section of the heater assembly 30.
  • a mechanism of the aerosol leakage is basically the same as the one illustrated in Fig. 12 . It should be noted, however, that the aerosol flowing backward through the second channel 82 (aerosol flow R2) passes outside the cylindrical member 90.
  • At least part of the second channel 82 comprises the cylindrical member 90.
  • at least part of the second channel 82 is separated away from the columnar member 110, which improves an efficiency of cooling the aerosol flowing backward through the intake channel.

  • the second channel 82 includes a channel extending in two directions (the channels 82 1 and 82 2 ) (see Figs. 11 and 16 ).
  • the embodiment and the like are not limited to the configuration mentioned above.
  • the second channel 82 may include a channel extending in one direction (for example, either one of the channels 82 1 and 82 2 ).
  • the second channel 82 may have a shape extending in a spiral manner along the outer periphery of the aerosol channel (columnar member 110 or cylindrical member 90). With such a configuration, the second channel 82 is increased in channel length, which improves the efficiency of cooling the aerosol flowing backward through the intake channel.
  • the second channel 82 has the shape extending along the outer periphery of the aerosol channel (columnar member 110 or cylindrical member 90).
  • the embodiment does not necessarily have to include the second channel 82 in such a shape.
  • the second channel 82 may have a shape extending along the inner periphery of the aerosol channel.
  • the second channel 82 may be disposed in an inner side of the sixth channel 86 so that the second channel 82 is divided by the sixth channel 86 and a partition wall or the like.
  • the heater 50 may be provided only in the holding portion 42A of the container 40 without being provided in the separated portion 42B of the container 40. With such a configuration, the heater 50 is not disposed in a region that does not contribute to the heating of the columnar member 110 (a region adjacent to the third channel 83). This suppresses a decrease in efficiency of cooling the aerosol flowing backward through the third channel 83.
  • the embodiment and the like illustrate the case where the heater 50 is disposed in the outer lateral face of the container 40.
  • the embodiment is not limited to the foregoing case.

  • the first channel 81, the second channel 82, and the sixth channel 86 may be provided as separate hollow spaces partitioned by partition walls or the like.
  • the heater assembly 30 includes the single channel group as a channel group of the first channel 81, the second channel 82, and the third channel 83, albeit having a configuration that the second channel 82 is divided.
  • the heater assembly 30 may include two or more channel groups.
  • the two or more channel groups may be so configured as not to be connected to each other.
  • the two or more channel groups also may share at least some channels.
  • the heater assembly 30 may include two or more first channels 81 and further include a second channel 82 connected to all of the two or more first channels 81.
  • the heater assembly 30 may include a single third channel 83 or two or more third channels 83.
  • the above-discussed embodiment and the like illustrate the case where the aerosol source is solid.
  • the embodiment and the like do not necessarily have to include such an aerosol source.
  • the aerosol source may be liquid.
