     Embodiment 
     (Non-Burning Type Flavor Inhaler) 
     A non-burning type flavor inhaler according to an embodiment will be described below.  FIG. 1  is a cross-sectional view illustrating a non-burning type flavor inhaler  1  according to the embodiment.  FIG. 2  is a cross-sectional view illustrating a power source unit  10  according to the embodiment.  FIG. 3  is a cross-sectional view illustrating a first cartridge  20  according to the embodiment.  FIG. 4  is a diagram illustrating an internal structure of the first cartridge  20  according to the embodiment. It should be noted that a reservoir  21  that will be described later is omitted from  FIG. 4 .  FIG. 5  is a side view illustrating a second cartridge  30  according to the embodiment.  FIG. 6  is an exploded perspective view of the second cartridge  30  according to the embodiment.  FIG. 7  is a cross-sectional view (cross-sectional view taken along A-A illustrated in  FIG. 5 ) illustrating a flavor source container  31  according to the embodiment.  FIG. 8  is a cross-sectional view (cross-sectional view taken along B-B illustrated in  FIG. 7 ) illustrating the flavor source container  31  according to the embodiment. It should be noted that a flavor source  31 A that will be described later is omitted from  FIG. 6 . 
     As illustrated in  FIG. 1 , the non-burning type flavor inhaler  1  has a shape extending in a predetermined direction A from a non-mouthpiece end toward a mouthpiece end. The non-burning type flavor inhaler  1  is an instrument for inhaling flavor without burning. 
     Specifically, the non-burning type flavor inhaler  1  has the power source unit  10 , the first cartridge  20 , and the second cartridge  30 . The first cartridge  20  is attachable to and detachable from the power source unit  10 , and the second cartridge  30  is attachable to and detachable from the first cartridge  20 . In other words, the first cartridge  20  and the second cartridge  30  are each replaceable. 
     As illustrated in  FIG. 2 , the power source unit  10  has a shape extending along the predetermined direction A, and has at least a battery  11 . The battery  11  may be a disposable battery and may be a rechargeable battery. An initial value of output voltage of the battery  11  is preferably in a range of from 1.2 to 4.2 V. In addition, the battery capacity of the battery  11  is preferably in a range of from 100 to 1000 mAh. 
     As illustrated in  FIG. 3  and  FIG. 4 , the first cartridge  20  has a shape extending along the predetermined direction A. The first cartridge  20  has a reservoir  21 , an atomizer  22 , a flow path forming body  23 , an outer frame  24 , and an end cap  25 . The first cartridge  20  has a first flow path  20 X provided on the downstream than the atomizer  22  as an aerosol flow path extending along the predetermined direction A. It should be noted that in the aerosol flow path, a side near to the atomizer  22  is referred to as upstream and a side away from the atomizer  22  is referred to as downstream. 
     The reservoir  21  retains an aerosol source  21 A. The reservoir  21  is positioned on the periphery of the flow path forming body  23  in a cross section orthogonal to the first flow path  20 X (predetermined direction A). In the embodiment, the reservoir  21  is positioned in a gap between the flow path forming body  23  and the outer frame  24 . For example, the reservoir  21  is constituted by a porous body such as a resin web or cotton. However, the reservoir  21  may be constituted by a tank that accommodates the liquid aerosol source  21 A. The aerosol source  21 A includes a liquid such as glycerin or propylene glycol. 
     The atomizer  22  atomizes the aerosol source  21 A not accompanying burning caused by power supplied from the battery  11 . In the embodiment, the atomizer  22  is constituted by a heating wire (coil) wound at a predetermined pitch, and preferably the atomizer  22  is constituted by a heating wire that has a resistance value in the range of from 1.0 to 3.0Ω. The predetermined pitch is a value or more such that the heating wires do not contact, and preferably is a small value. For example, the predetermined pitch is preferably 0.40 mm or less. The predetermined pitch is preferably fixed to stabilize atomization of the aerosol source  21 A. Note that, the predetermined pitch is an interval in the center of heating wires that are adjacent to each other. 
     The flow path forming body  23  has a shape extending along the predetermined direction A. The flow path forming body  23  has a cylindrical shape that forms the first flow path  20 X extending along the predetermined direction A. 
     The outer frame  24  has a shape extending along the predetermined direction A. The outer frame  24  has a cylindrical shape that accommodates the flow path forming body  23 . In the embodiment, the outer frame  24  accommodates a part of the second cartridge  30  while extending to the downstream side than the end cap  25 . 
     The end cap  25  is a cap that closes a gap between the flow path forming body  23  and the outer frame  24  from the downstream side. The end cap  25  suppresses a situation such that the aerosol source  21 A retained in the reservoir  21  leaks to the second cartridge  30  side. 
     As illustrated in  FIG. 5  and  FIG. 6 , the second cartridge  30  has at least the flavor source  31 A. The second cartridge  30  is mounted in the non-burning type flavor inhaler  1 . In the embodiment, the second cartridge  30  is connected to the first cartridge  20 . More particularly, a part of the second cartridge  30  is accommodated in the outer frame  24  of the first cartridge  20  as described above. 
     The second cartridge  30  has a shape extending along the predetermined direction A. The second cartridge  30  has the flavor source container  31 , a mesh body  32 , a filter  33 , and a cap  34 . The second cartridge  30  has a second flow path  30 X provided on the downstream than the first flow path  20 X as the aerosol flow path. 
     The second cartridge  30  imparts flavor to the aerosol by letting the aerosol atomized by the atomizer  22  pass through. Here, in the embodiment, it should be noted that it is possible to impart flavor to the aerosol without heating the flavor source  31 A. It should be noted that the aerosol is not practically generated from the flavor source  31 A. 
     In the predetermined direction A, preferably a maximum size of the second cartridge  30  is 40 mm or less. Furthermore, in the predetermined direction A, preferably the maximum size of the second cartridge  30  is 25 mm or less. Meanwhile, in the predetermined direction A, preferably a minimum size of the second cartridge  30  is 5 mm or more. Furthermore, in the predetermined direction A, preferably the minimum size of the second cartridge  30  is 1 mm or more. In a direction orthogonal to the predetermined direction A, preferably the maximum size of the second cartridge  30  is 20 mm or less. Furthermore, in the direction orthogonal to the predetermined direction A, preferably the maximum size of the second cartridge  30  is 10 mm or less. Meanwhile, in the direction orthogonal to the predetermined direction A, preferably the minimum size of the second cartridge  30  is 3 mm or more. Furthermore, in the direction orthogonal to the predetermined direction A, preferably the minimum size of the second cartridge  30  is 1 mm or more. 
     The flavor source container  31  has a cylindrical shape and forms the second flow path  30 X extending along the predetermined direction A. The flavor source container  31  accommodates the flavor source  31 A. The flavor source  31 A that imparts flavor to the aerosol is accommodated in the second flow path  30 X. Here, in a cross section orthogonal to the aerosol flow path (predetermined direction A), preferably the size of the first flow path  20 X is small to secure volume of the reservoir  21  that retains the aerosol source  21 A. Accordingly, in a case in which the second cartridge  30  is accommodated in the outer frame  24  that has a fixed cross-sectional area across the aerosol flow path (predetermined direction A), as a result, the size of the second flow path  30 X tends to be larger than the size of the first flow path  20 X described above. 
     The flavor source  31 A is constituted by raw material pieces that impart flavor to the aerosol generated by the non-burning type flavor inhaler  1 . Preferably the lower limit of the size of the raw material pieces is from 0.2 to 1.2 mm. Furthermore, preferably the lower limit of the size of the raw material pieces is from 0.2 to 0.7 mm. The smaller the size of the raw material pieces included in the flavor source  31 A, the more the specific surface area increases, therefore a flavor component tends to be released from the raw material pieces included in the flavor source  31 A. It is possible to use shredded tobacco or a molded body in which a tobacco raw material is granularly formed as the raw material pieces included in the flavor source  31 A. The flavor source  31 A may be constituted by a plant other than tobacco (for example, mint and herbs). Flavorings such as menthol may be added to the flavor source  31 A. 
     Here, for example, the raw material pieces included in the flavor source  31 A are obtained by sieving compliant with JIS Z 8815 using a stainless steel sieve compliant with JIS Z 8801. For example, the raw material pieces that pass through the stainless steel sieve that has sieve openings of 0.71 mm are obtained by sieving the raw material pieces over 20 minutes by a drying and mechanical shaking method using the stainless steel sieve that has the sieve openings of 0.71 mm. Subsequently, the raw material pieces that pass through the stainless steel sieve that has sieve openings of 0.212 mm are removed by sieving the raw material pieces over 20 minutes by the drying and mechanical shaking method using the stainless steel sieve that has the sieve openings of 0.212 mm. That is, the raw material pieces included in the flavor source  31 A are raw material pieces that pass through the stainless steel sieve (sieve openings=0.71 mm) that regulates the upper limit and do not pass through the stainless steel sieve (sieve openings=0.212 mm) that regulates the lower limit. Accordingly, in the embodiment, the lower limit of the size of the raw material pieces included in the flavor source  31 A is defined by the sieve openings of the stainless steel sieve that regulates the lower limit. Note that, the upper limit of the size of the raw material pieces included in the flavor source  31 A is defined by the sieve openings of the stainless steel sieve that regulates the upper limit. 
     In the embodiment, as illustrated in  FIG. 6  and  FIG. 7 , preferably the flavor source container  31  has a protruding portion  31 E that protrudes to the upstream side (in the embodiment, the flow path forming body  23  or the end cap  25  side) from an outer edge of an upstream end portion (here, the mesh body  32 ) of the flavor source container  31  in a cross section orthogonal to the aerosol flow path (predetermined direction A). The protruding portion  31 E may be continuously provided along the outer edge of the upstream end portion (here, the mesh body  32 ) of the flavor source container  31  and may be intermittently provided along the outer edge of the flavor source container  31 . Note that, when there is a gap between the outer frame  24  and the flavor source container  31 , preferably the protruding portion  31 E is continuously provided along the outer edge of the upstream end portion (here, the mesh body  32 ) of the flavor source container  31 . Thereby, it is possible to suppress retention of aerosol in the gap formed in the upstream part of a taper part  31 T. 
     In the embodiment, as illustrated in  FIG. 6  and  FIG. 7 , preferably an outer wall surface of the flavor source container  31  includes the taper part  31 T that becomes wide from the upstream to the downstream. The taper part  31 T may be contained in a part of the outer wall surface of the flavor source container  31 . For example, a taper angle α of the taper part  31 T is approximately 5 degrees. 
     In the embodiment, as illustrated in  FIG. 7 , preferably a rib  31 R extending along the predetermined direction A from the upstream to the downstream is provided in an inner wall surface of the flavor source container  31 . Although not particularly limited, preferably the number of ribs  31 R is two or more. Preferably the downstream end portion of the ribs  31 R does not reach the downstream end portion of the flavor source container  31 . For example, in the predetermined direction A, a length L 2  from the mesh body  32  to the downstream end portion of the ribs  31 R is shorter than a length L 1  from the mesh body  32  to the downstream end portion of the flavor source container  31 . In other words, in a state in which the filter  33  is inserted in the flavor source container  31 , preferably the downstream end portion of the ribs  31 R contacts the filter  33  without reaching the downstream end portion of the flavor source container  31 . 
     The mesh body  32  is provided on the upstream (non-mouthpiece side) than the flavor source  31 A. In the embodiment, the mesh body  32  is provided on the upstream end portion of the flavor source container  31 . When the mesh body  32  provided in the flavor source container  31  is very small, from the perspective of securing strength of the mesh body  32 , preferably the flavor source container  31  and the mesh body  32  are integrally formed. That is, in the embodiment, the mesh body  32  is a part of the flavor source container  31 . In such a case, preferably the flavor source container  31  and the mesh body  32  are configured by resin. For example, it is possible to use one or more resins that are selected from polypropylene, polyethylene terephthalate, polyethylene resin, and ABS resin as the resin. From the perspective of moldability and texture, preferably the resin is polypropylene. The flavor source container  31  and the mesh body  32  are constituted by metallic molding or injection molding. 
     In the embodiment, as illustrated in  FIG. 8 , the mesh body  32  has a plurality of openings  32 A. Each of the plurality of openings  32 A has a polygon shape that has an internal angle of 180° or less. Each of the plurality of openings  32 A has, as widths through which each center of gravity of the plurality of openings  32 A passes, a minimum width Wmin having the smallest width and a maximum width Wmax having the largest width. The minimum width Wmin is smaller than the lower limit of the size of the raw material pieces included in the flavor source  31 A. More particularly, since the raw material pieces that actually constitutes the flavor source  31 A are non-spherical, from the perspective of suppressing drop out of the raw material pieces, preferably the minimum width Wmin is smaller than ½ the lower limit of the size of the raw material pieces included in the flavor source  31 A. The maximum width Wmax is larger than the minimum width Wmin. For example, preferably the maximum width Wmax is larger than the lower limit of the size of the raw material pieces. Alternatively, preferably the maximum width Wmax is from √2 times to six times of the minimum width Wmin. That is, each of the plurality of openings  32 A is a shape different from a circle. Furthermore, since the raw material pieces tend not to fit in the opening  32 A, preferably each of the plurality of openings  32 A is a rectangular shape. Note that, each side of the rectangular shape that the opening  32 A may include a nonlinear part generated in manufacturing the opening  32 A. In addition, each vertex of the rectangular shape that the opening  32 A may include a curved part generated in manufacturing the opening  32 A. 
     Here, as illustrated in  FIG. 9  to  FIG. 12 , preferably each of the plurality of openings  32 A has a shape selected from square, rectangular, diamond, hexagonal, and octagonal. As illustrated in  FIG. 9  to  FIG. 11 , the shape of each of the plurality of openings  32 A may be one type, and as illustrated in  FIG. 12 , may be two types. The shape of each of the plurality of openings  32 A may be three types or more. Note that, from the perspective of arrangement efficiency, manufacturability, or the like of the plurality of openings  32 A, preferably each of the plurality of openings  32 A has a rectangular shape. 
     In the examples illustrated in  FIG. 9  to  FIG. 12 , preferably the plurality of openings  32 A are provided such that sides of the openings  32 A adjacent to each other become parallel. Preferably an interval P of the openings  32 A adjacent to each other is from 0.15 to 0.30 mm. In such a case, preferably the thickness of the mesh body  32  is from 0.1 to 1 mm. 
     The filter  33  is configured by a predetermined fiber and has a roughness to a degree such that the raw material pieces do not pass through. The filter  33  is provided on the downstream than the flavor source  31 A. For example, the filter  33  is an acetate filter. The cap  34  is provided on the downstream (on the mouthpiece side) than the filter  33 . 
     Note that, preferably the flavor source container  31  (here, containing the mesh body  32 ), the filter  33 , and the cap  34  are adhered or welded to each other. 
     In the embodiment, preferably all openings provided in the mesh body  32  are the opening  32 A described above, but the embodiment is not limited to this. The openings provided in the mesh body  32  may include openings other than the opening  32 A described above. 
     (Connection State) 
     Hereinafter, a connection state of the first cartridge  20  and the second cartridge  30  according to the embodiment will be described.  FIG. 13  is a diagram illustrating a connection state of the first cartridge  20  and the second cartridge  30  according to the embodiment.  FIG. 14  is a diagram illustrating the cross-section taken along C-C illustrated in  FIG. 13 . However, it should be noted that in  FIG. 13 , the reservoir  21 , the atomizer  22 , the flavor source  31 A, the filter  33 , and the cap  34  are omitted. 
     As illustrated in  FIG. 13 , an aerosol flow adjustment chamber G that adjusts the flow of aerosol supplied from the first flow path  20 X is provided between the first flow path  20 X and the second flow path  30 X such that polarization of the flow of the aerosol in the second flow path  30 X is suppressed. In the embodiment, the aerosol flow adjustment chamber G is formed between the downstream end portion of the flow path forming body  23  and the upstream end portion of the flavor source container  31 . More particularly, the aerosol flow adjustment chamber G is formed between the end cap  25  and the mesh body  32 . 
     Here, a filling rate of the flavor source  31 A accommodated in the flavor source container  31  may not be 100% of the capacity of the flavor source container  31 . That is, a gap may be formed in the flavor source container  31 . However, it is needless to say that the aerosol flow adjustment chamber G has a different gap generated by the filling rate of the flavor source  31 A not being 100%. 
     In the embodiment, in a cross section orthogonal to the predetermined direction A, a shifted distance may be defined by a distance from an outer edge of the first flow path  20 X to an outer surface of the second flow path  30 X on a line from the center of gravity of the first flow path  20 X toward the outside of the first flow path  20 X. A length LG of the aerosol flow adjustment chamber G in the predetermined direction A may be determined based on the largest shift distance among the shift distances. That is, the length LG of the aerosol flow adjustment chamber G may be determined according to the largest shift distance. From the perspective of suppressing polarization of flow of the aerosol that flows inside the flavor source container  31 , preferably the longer the largest shift distance, the longer the length LG of the aerosol flow adjustment chamber G. Preferably the length LG of the aerosol flow adjustment chamber G is 1/10 or more of the largest shift distance. 
     For example, as illustrated in  FIG. 14 , in the cross section orthogonal to the predetermined direction A, when the first flow path  20 X and the second flow path  30 X are coaxial circles, the length LG of the aerosol flow adjustment chamber G in the predetermined direction A is determined according to a difference (that is, the shift distance) between a radius R 1  of the first flow path  20 X and a radius R 2  of the second flow path  30 X. 
     In the embodiment, as described above, the flavor source container  31  has a protruding portion  31 E that protrudes to the upstream side (in the embodiment, the flow path forming body  23  or the end cap  25  side) from an outer edge of an upstream end portion (here, the mesh body  32 ) of the flavor source container  31  in a cross section orthogonal to the aerosol flow path (predetermined direction A). That is, the flavor source container  31  has the protruding portion  31 E (first protruding portion) as a spacer that forms the aerosol flow adjustment chamber G. 
     In the embodiment, preferably the entirety of the downstream end portion of the flow path forming body  23  (first flow path  20 X) is exposed to the aerosol flow adjustment chamber G. Preferably the entirety of the upstream end portion of the flavor source container  31  (second flow path  30 X) is exposed to the aerosol flow adjustment chamber G. Thereby, it is possible to effectively adjust the flow of the aerosol led from the first flow path  20 X to the second flow path  30 X using the aerosol flow adjustment chamber G. 
     Preferably the aerosol flow adjustment chamber G does not contain a part that protrudes more to the upstream side than the downstream end portion of the flow path forming body  23  (first flow path  20 X). Preferably the aerosol flow adjustment chamber G does not contain a part that protrudes more to the downstream side than the upstream end portion of the flavor source container  31  (second flow path  30 X). Thereby, it is possible to suppress retention of aerosol in an unnecessary gap. 
     Preferably an inner wall surface that constitutes the aerosol flow adjustment chamber G is continuous without including a step from the outer edge of the downstream end portion of the flow path forming body  23  (first flow path  20 X) across the outer edge of the upstream end portion of the flavor source container  31  (second flow path  30 X). 
     In the embodiment, as illustrated in  FIG. 13  and  FIG. 14 , in the cross section orthogonal to the aerosol flow path (predetermined direction A), preferably an outer edge  25 out of the end cap  25  contacts an inner wall surface  24 in of the outer frame  24  and an inner edge  25 in of the end cap  25  is positioned between the outer edge  23 out of the flow path forming body  23  and the inner edge  23 in of the flow path forming body  23 . Thereby, it is difficult to remove the end cap  25  from the downstream side. In addition, when the end cap  25  is provided inside the outer frame  24 , it is difficult for the end cap  25  to interfere with the flow path forming body  23 . 
     (Control Circuit) 
     A control circuit according to the embodiment will be mainly described below.  FIG. 15  is a diagram mainly illustrating a function block of a control circuit  50  according to an embodiment. 
     As illustrated in  FIG. 15 , the non-burning type flavor inhaler  1  has a notification unit  40  and the control circuit  50 . 
     The notification unit  40  notifies a variety of information. The notification unit  40  may be constituted by a light emitting element, may be constituted by a vibration element, and may be constituted by a sound output element. The notification unit  40  may combine two or more elements out of the light emitting element, the vibration element, and the sound output element. Preferably the notification unit  40  is provided in the power source unit  10 , but the embodiment is not limited thereto. The notification unit  40  may be provided in the first cartridge  20  and may be provided in the second cartridge  30 . 
     The control circuit  50  has a detector  51 , a notification controller  52 , and a power controller  53 . 
     The detector  51  detects the puff action. In such a case, the detector  51  is connected to an inhalation sensor and detects the puff action based on an output result of the inhalation sensor. In addition, the detector  51  detects power supply from the battery  11  to the atomizer  22 . In such a case, the detector  51  is connected to a voltage sensor provided on a power line that connects the battery  11  and the atomizer  22  and detects power supply based on the output result of the voltage sensor. 
     The notification controller  52  controls the notification unit  40  to notify various information. For example, the notification controller  52  controls the notification unit  40  to notify a replacement timing of the second cartridge  30  according to detection of the replacement timing of the second cartridge  30 . As described above, the notification unit  40  may notify the replacement timing of the second cartridge  30  due to light emission by the light emitting element, may notify the replacement timing of the second cartridge  30  due to vibration by the vibration element, and may notify the replacement timing of the second cartridge  30  due to sound output by the sound output element. 
     Here, the notification controller  52  detects the replacement timing of the second cartridge  30  based on the number of puff actions or an energization time of the atomizer  22 . Note that, the number of puff actions may be set according to the puff action detected by the detector  51  described above. In the same manner, the energization time of the atomizer  22  may be set according to the power supply detected by the detector  51  described above. 
     Specifically, the notification controller  52  has a counter  52 X that counts the number of puff actions or the energization time of the atomizer  22 . When a count value of the counter  52 X reaches a predetermined value, the notification controller  52  detects the replacement timing of the second cartridge  30  and resets the count value of the counter  52 X. Note that, preferably the notification controller  52  resets the count value of the counter  52 X after the second cartridge  30  is replaced. Alternatively, when the count value of the counter  52 X reaches the predetermined value, the notification controller  52  notifies the replacement timing of the second cartridge  30  and resets the count value of the counter  52 X according to the predetermined operation of the user. when a hardware interface (for example, a switch or button) for switching the power source of the non-burning type flavor inhaler  1  on or off or a hardware interface (for example, a switch or a button) for controlling power supply to the atomizer  22  is provided in the non-burning type flavor inhaler  1 , the predetermined operation of the user may be an operation of the hardware interface. Alternatively, the predetermined user operation may be an operation of taking in breath from the mouthpiece of the non-burning type flavor inhaler  1  if it is possible for the detector  51  to detect the puff action. Alternatively, the predetermined operation of the user may be an operation of inhaling breath (for example, an operation of inhaling two times in a short time) in a mode in which it is possible for the detector  51  to detect the puff action and it is possible to identify a general puff action. The counter  52 X may be a count type counter and may be a countdown type counter. 
     In the embodiment, preferably the notification controller  52  controls the notification unit  40  to notify the replacement timing of the first cartridge  20  according to detection of the replacement timing of the first cartridge  20 . In such a case, preferably the notification controller  52  detects the replacement timing of the first cartridge  20  based on the number of replacement times of the second cartridge  30 . More particularly, the notification controller  52  detects the replacement timing of the first cartridge  20  when the number of replacement times of the second cartridge  30  reaches a predetermined number of times. 
     In the embodiment, preferably the notification controller  52  controls the notification unit  40  to notify the replacement timing of the battery  11  or the charging timing of the battery  11  according to detection of the replacement timing of the battery  11  or the charging timing of the battery  11 . In such a case, preferably the notification controller  52  detects the replacement timing of the battery  11  or the charging timing of the battery  11  based on output voltage of the battery  11 . More particularly, preferably the notification controller  52  detects the replacement timing or the charging timing of the battery  11  when the output voltage of the battery  11  is a predetermined threshold. 
     However, the embodiment is not limited thereto, but the notification controller  52  may detect the replacement timing of the battery  11  or the charging timing of the battery  11  based on the number of puff actions or the energization time of the atomizer  22 . More particularly, the notification controller  52  may detect the replacement timing of the battery  11  or the charging timing of the battery  11  when the number of puff actions or the energization time of the atomizer  22  exceeds the predetermined threshold. 
     Note that, the notification unit  40  notifies the replacement timing of the first cartridge  20 , the replacement timing of the battery  11 , or the charging timing of the battery  11  according to the light emission of the light emitting element, the vibration of the vibration element, or the output sound of the sound output element in the same manner as the replacement timing of the second cartridge  30 . 
     The power controller  53  outputs a predetermined instruction to the battery  11  as an instruction to the battery  11 , the predetermined instruction instructing the battery  11  to make the aerosol amount, atomized by the atomizer  22 , falls within the desired range. The output of the predetermined instruction may be performed one time in each puff action. In addition, it should be noted that the power controller  53  instructs output of power to the atomizer  22  to the battery  11  in the puff period in which the puff action is performed, but does not instruct output of power to the atomizer  22  to the battery  11  in the non-puff period in which the puff action is not performed. Note that, the puff period and the non-puff period may be set according to the puff action detected by the detector  51  described above. 
     Here, the power controller  53  controls the predetermined instruction such that the aerosol amount atomized by the atomizer  22  falls within the desired range. For example, the power controller  53  modifies the predetermined instruction accompanying a reduction of the accumulated amount in the battery  11 . In addition, the power controller  53  stops power supply from the battery  11  to the atomizer  22  when the predetermined period elapses from the start of power supply to the atomizer  22 . In other words, the power controller  53  stops power supply from the battery  11  to the atomizer  22  when the puff period exceeds the predetermined period even in the puff period in which the puff action is actually performed by the user. 
     In addition, the power controller  53  stops power supply from the battery  11  to the atomizer  22  when the puff action ends even prior to the predetermined period elapse from the start of the puff action. Thereby, since the aerosol is not generated in the period in which the puff action is not performed (non-puff period), it is possible to suppress a situation in which droplets are generated by retaining and condensing the aerosol in the aerosol flow path in the non-puff period and the aerosol generated by the puff action next to the non-puff period is trapped in the droplets, and suppress a concern of hindering supply of the aerosol amount in the desired range, deterioration of taste caused by the droplets, and the like. 
     Here, the predetermined period is shorter than the upper limit value of the standard puff period derived from statistics of the puff period of the user. Furthermore, preferably the predetermined period is shorter than an average value of the puff period derived from statistics of the puff period of the user. Of course, the average value of the puff period is shorter than the upper limit value of the standard puff period. 
     Since the predetermined period is determined to suppress variation of the puff period of the user, it is necessary for there to be a certain number or more of users whose puff period is longer than the predetermined period. From such a perspective, preferably the predetermined period is derived from statistics. Furthermore, since it is possible for the energization time of the atomizer  22  in most puff actions is fixed in the predetermined period by the predetermined period being shorter than the average value of the puff period derived from statistics, it is possible to suppress variation of the aerosol amount caused by variance of the puff period of the user. 
     For example, the predetermined period is from one to three seconds. By the predetermined period being one second or more, the energization time of the atomizer  22  is not too short compared to the puff period, and therefore discomfort imparted to the user is mitigated. Meanwhile, it is possible to set the puff action in which the energization time of the atomizer  22  is fixed to the predetermined period to a certain number or more by the predetermined period being three seconds or less. 
     Furthermore, the predetermined period may be from 1.5 to 2.5 seconds. Thereby, it is possible to mitigate discomfort imparted to the user, and increase the puff action in which the energization time of the atomizer  22  is fixed to the predetermined period. 
     In the embodiment, preferably the predetermined period is set in advance. In such a case, preferably the predetermined period is determined according to the standard puff period derived from statistics of puff periods of a plurality of users. 
     Note that, the standard puff period may be derived from statistics of puff periods of users, and is a period between the lower limit value of puff periods of a plurality of users and the upper limit value of puff periods of a plurality of users. The lower limit value and the upper limit value, for example, may be derived from the upper limit value and the lower limit value of a 95% confidence interval of the average value and may be derived as m±no (here, m is the average value, σ is standard deviation, and n is a positive real number) based on distribution of puff period data of the users. 
     In the embodiment, preferably the power controller  53  modifies (or corrects) the predetermined instruction such that the aerosol amount atomized by the atomizer  22  falls within the desired range accompanying the reduction of the accumulated amount in the battery  11 . For example, when the amount of power supplied from the battery  11  to the atomizer  22  is controlled by pulse control, preferably the power controller  53  increases a duty ratio output to the battery  11  in one puff action accompanying the reduction of the accumulated amount in the battery  11  as a modification of the predetermined instruction. 
     As illustrated in  FIG. 16 , for example, the power controller  53  controls an interval (pulse interval) of an on time at which power is supplied from the battery  11  to the atomizer  22 . Specifically, the power controller  53  increases the duty ratio output to the battery  11  in one puff action by modifying a pulse interval P 1  to a pulse interval P 2 . 
     Alternatively, as illustrated in  FIG. 17 , the power controller  53  controls a length (pulse width) of the on time at which power is supplied from the battery  11  to the atomizer  22 . Specifically, the power controller  53  increases the duty ratio output to the battery  11  in one puff action by modifying a pulse width W 1  to a pulse width W 2 . 
     Note that, the power controller  53  may gradually increase the duty ratio and may continuously increase the duty ratio as a modification of the predetermined instruction accompanying the reduction of the accumulated amount in the battery  11 . 
     In the embodiment, preferably the power controller  53  estimates the accumulated amount in the battery  11  based on a voltage value output from the battery  11 . Alternatively, the power controller  53  may estimate the accumulated amount in the battery  11  based on the number of times of the puff action and the energization time of the atomizer  22 . Note that, the number of puff actions may be set according to the puff action detected by the detector  51  described above. In the same manner, the energization time of the atomizer  22  may be set according to the power supply detected by the detector  51  described above. 
     In the embodiment, preferably the power controller  53  stops the power supply from the battery  11  to the atomizer  22  from the count value of the counter  52 X reaching the predetermined value until the count value is reset. In other words, preferably the power controller  53  stops the power supply from the battery  11  to the atomizer  22  from the notification of the replacement timing of the second cartridge  30  until the count value is reset. That is, power supply from the battery  11  to the atomizer  22  is stopped until the second cartridge  30  is replaced. Accordingly, use of the second cartridge  30 , in which it is only possible to impart a small amount of flavor to the aerosol, is suppressed. 
     (Control Method) 
     A control method according to the embodiment will be described below.  FIG. 18  is a flowchart illustrating the control method according to the embodiment.  FIG. 18  is a flowchart illustrating the control method of the amount of power supplied from the battery  11  to the atomizer  22  in one puff action. It is noted that the flow illustrated in  FIG. 18  starts in response to detection of the start of the puff action. 
     It is noted that as the premise of the flow illustrated in  FIG. 18 , the non-burning type flavor inhaler  1  (that is, the power controller  53 ) instructs to the battery  11  output of power to the atomizer  22  in the puff period in which the puff action is performed, but does not instruct to the battery  11  output of power to the atomizer  22  in the non-puff period in which the puff action is not performed. 
     As illustrated in  FIG. 18 , in step S 10 , the non-burning type flavor inhaler  1  (that is, the power controller  53 ) estimates the accumulated amount in the battery  11 . As described above, preferably the non-burning type flavor inhaler  1  estimates the accumulated amount in the battery  11  based on the voltage value output from the battery  11 . 
     In step S 20 , the non-burning type flavor inhaler  1  (that is, the power controller  53 ) determines the predetermined instruction (for example, the duty value) output to the battery  11 . More particularly, the non-burning type flavor inhaler  1  determines the duty ratio output to the battery  11  such that the duty ratio increases along with the reduction of the accumulated amount in the battery  11 . In other words, the non-burning type flavor inhaler  1  increases the duty ratio as a modification of the predetermined instruction. 
     In step S 30 , the non-burning type flavor inhaler  1  (that is, the power controller  53 ) determines whether or not the predetermined period elapses from the start of power supply to the atomizer  22 . In other words, the non-burning type flavor inhaler  1  determines whether or not the puff period exceeds the predetermined period. When the determination result is YES, the non-burning type flavor inhaler  1  transitions to a process in step S 50 , and when the determination result is NO, the non-burning type flavor inhaler  1  transitions to a process in step S 40 . 
     In step S 40 , the non-burning type flavor inhaler  1  (that is, the power controller  53 ) estimates whether or not the puff action ends. When the determination result is NO, the non-burning type flavor inhaler  1  returns to the process in step S 30 , and when the determination result is YES, the non-burning type flavor inhaler  1  stops power supply to the atomizer  22  and ends the series of processes. Note that, as described above, the end of the puff action may be detected by the detector  51  if it is possible for the detector  51  to detect the puff action. Alternatively, the end of the puff action may be detected according to the operation of the hardware interface (for example, the switch or the button) for switching whether or not power is supplied to the atomizer  22 . 
     In step S 50 , the non-burning type flavor inhaler  1  (that is, the power controller  53 ) stops power supply from the battery  11  to the atomizer  22  even in the puff period in which the puff action is actually performed by the user. 
     (Operation and Effect) 
     In the embodiment, the power controller  53  stops power supply from the battery  11  to the atomizer  22  when the predetermined period elapses from starting power supply to the atomizer  22 . The predetermined period is shorter than the upper limit value of the standard puff period derived from statistics of puff periods of users. Accordingly, even if the non-burning type flavor inhaler is used by the user who has a puff period longer than the predetermined period, it is easy to suppress an extreme decrease of the accumulated amount in the battery  11  and easy to control the predetermined instruction such that the aerosol amount atomized by the atomizer  22  falls within the desired range. 
     In this manner, it is possible that the aerosol amount supplied per one puff action falls within the desired range through the puff action from the start of smoking (an initial stage in which an accumulated amount in a battery  11  is sufficient) until the end of smoking (that is, a final stage in which the accumulated amount in the battery  11  decreases), regardless of the length of a puff period of the user and the accumulated amount in the battery  11 . 
     In the embodiment, the power controller  53  modifies the predetermined instruction output to the battery  11  in one puff action accompanying the reduction of the accumulated amount in the battery  11 . It is possible to suppress a difference in the amount of power actually supplied from the battery  11  to the atomizer  22  between an initial step in which the accumulated amount in the battery  11  is sufficient and a final stage in which the accumulated amount in the battery  11  is insufficient. Thereby, it is possible for the aerosol amount atomized by the atomizer  22  to fall in the desired range regardless of the length of the puff period of the user and the accumulated amount in the battery  11 . 
     In the embodiment, the notification controller  52  controls the notification unit  40  to notify a replacement timing of the second cartridge  30  according to detection of the replacement timing of the second cartridge  30 . Accordingly, it is possible for the user to easily ascertain the replacement timing of the second cartridge  30 . 
     In the embodiment, the notification controller  52  controls the notification unit  40  to notify the replacement timing of the first cartridge  20  according to detection of the replacement timing of the first cartridge  20 . Accordingly, it is possible for the user to easily ascertain the replacement timing of the first cartridge  20 . 
     In the embodiment, the notification controller  52  detects the replacement timing (lifespan) of the first cartridge  20  based on the number of replacement times of the second cartridge  30 . Accordingly, detection of the replacement timing of the first cartridge  20  is easy. Furthermore, it is possible to mitigate a possibility that the lifespan of the first cartridge  20  comes to an end while the second cartridge  30  is in use. Note that, of course the replacement timing (lifespan) of the first cartridge  20  corresponds to the number (number of times of replacement) of the second cartridge  30  usable in one first cartridge  20 . 
     In the embodiment, the notification controller  52  controls the notification unit  40  to notify the replacement timing of the battery  11  or the charging timing of the battery  11  according to detection of the replacement timing of the battery  11  or the charging timing of the battery  11 . Accordingly, it is possible for the user to easily ascertain the replacement timing of the battery  11  or the charging timing of the battery  11 . 
     In the embodiment, the power controller  53  stops the power supply from the battery  11  to the atomizer  22  from the count value of the counter  52 X reaching the predetermined value until the count value is reset. Accordingly, power supply from the battery  11  to the atomizer  22  is stopped until the second cartridge  30  is replaced. Accordingly, use of the second cartridge  30 , in which it is only possible to impart a small amount of flavor to the aerosol, is suppressed. 
     In the embodiment, the power controller  53  stops power supply from the battery  11  to the atomizer  22  when the predetermined instruction is controlled such that the aerosol amount atomized by the atomizer  22  falls within the desired range and a predetermined period elapses from the start of power supply to the atomizer  22 . Accordingly, since the variation of the amount of power consumed in one puff action reduces, the detection accuracy of the replacement timing of the second cartridge  30  is improved when the replacement timing of the second cartridge  30  is detected based on the number of puff actions. 
     In the embodiment, an aerosol flow adjustment chamber G that adjusts the flow of aerosol supplied from the first flow path  20 X is provided between the first flow path  20 X and the second flow path  30 X such that polarization of the flow of the aerosol in the second flow path  30 X is suppressed. Thereby, the flavor source tends to pass through without the aerosol supplied from the first flow path  20 X biasing in the second cartridge  30 X. 
     In the embodiment, the reservoir  21  is positioned on the periphery of the flow path forming body  23  in a cross section orthogonal to the first flow path  20 X (predetermined direction A). Thereby, it is possible to secure the volume of the reservoir  21  in which the aerosol source  21 A is retained while suppressing the entire length of the first cartridge  20  in the first flow path  20 X (predetermined direction A). 
     In the embodiment, in the cross section orthogonal to the aerosol flow path (predetermined direction A), the size of the second flow path  30 X is larger than the size of the first flow path  20 X. In other words, since the first flow path  20 X is small in the cross section orthogonal to the aerosol flow path (predetermined direction A), it is possible to secure volume of the reservoir  21  positioned on the periphery of the flow path forming body  23 . Since the size of the second flow path  30 X is large in the cross section orthogonal to the aerosol flow path (predetermined direction A), it is possible to efficiently remove the flavor component from the flavor source  31 A. 
     In the embodiment, in the cross section orthogonal to the aerosol flow path (predetermined direction A), the outer edge  25 out of the end cap  25  contacts the inner wall surface  24 in of the outer frame  24  and the inner edge  25 in of the end cap  25  is positioned between the outer edge  23 out of the flow path forming body  23  and the inner edge  23 in of the flow path forming body  23 . Thereby, it is difficult to remove the end cap  25  from the downstream side. In addition, when the end cap  25  is provided inside the outer frame  24 , it is difficult for the end cap  25  to interfere with the flow path forming body  23 . 
     In the embodiment, in a cross section orthogonal to the predetermined direction A, when a distance from an outer edge of the first flow path  20 X to an outer surface of the second flow path  30 X is a shifted distance on a line from the center of gravity of the first flow path  20 X toward the outside of the first flow path  20 X, a length LG of the aerosol flow adjustment chamber G in the predetermined direction A is determined according to the largest shift distance. Thereby, it is possible to appropriately adjust the flow of the aerosol led from the first  20 X to the second flow path  30 X using the aerosol flow adjustment chamber G, and the flavor source  31 A tends to pass through without the aerosol supplied from the first flow path  20 X biasing in the second cartridge  30 . 
     In the embodiment, each of the plurality of openings  32 A provided in the mesh body  32  has a polygon shape that has an internal angle of 180° or less. Each of the plurality of openings  32 A has a minimum width Wmin having the smallest width and a maximum width Wmax having the largest width as widths through which each center of gravity of the plurality of openings  32 A passes. Here, since the minimum width Wmin is smaller than the size of the raw material pieces included in the flavor source  31 A, it is possible to suppress drop out of the raw material pieces included in the flavor source  31 A, and since the maximum width Wmax is larger than the minimum width Wmin, it is possible to increase an opening ratio for the entirety of the mesh body. 
     In this manner, it is possible to secure the opening ratio for the entirety of the mesh body  32  while suppressing drop out of the raw material pieces forming the flavor source in the second cartridge  30  for the non-burning type flavor inhaler. 
     In the embodiment, the maximum width Wmax of the opening  32 A is larger than the lower limit of the size of the raw material pieces included in the flavor source  31 A. Accordingly, the opening ratio is improved for the entirety of the mesh body  32 . 
     In the embodiment, the maximum width Wmax of the opening  32 A is from √2 times to six times of the minimum width Wmin of the opening  32 A. Accordingly, it is possible to improve the opening ratio for the entirety of the mesh body  32  by the maximum width Wmax being √2 times or more of the minimum width Wmin and maintain the strength of the mesh body  32  by the maximum width Wmax being six times or less of the minimum width Wmin. 
     In the embodiment, each of the plurality of openings  32 A has a shape selected from square, rectangular, diamond, hexagonal, and octagonal. The plurality of openings  32 A are provided such that sides of the openings  32 A adjacent to each other become parallel. The interval P of the openings  32 A that are adjacent to each other are from 0.15 to 0.30 mm. Thereby, it is possible to efficiently provide the plurality of openings  32 A, and it is possible to maintain the strength of the mesh body  32  while improving the opening ratio for the entirety of the mesh body  32 . 
     In the embodiment, the inner wall surface of the flavor source container  31  is provided with the rib  31 R extending along the predetermined direction A from the upstream to the downstream. Accordingly, the flavor component tends to be removed from the flavor source  31 A without the flow of the aerosol in the predetermined direction A being inhibited by the rib  31 R in the flavor source container  31  while the rib  31 R reinforces the flavor source container  31 . 
     In the embodiment, the outer wall surface of the flavor source container  31  includes the taper part  31 T that becomes wide from the upstream to the downstream. Accordingly, the second cartridge  30  tends to fit in the outer frame  24  of the first cartridge  20 , and drop out of the second cartridge  30  is suppressed while permitting manufacturing error of the outline of the flavor source container  31 . 
     In the embodiment, in the predetermined direction A, a length L 2  from the mesh body  32  to the downstream end portion of the rib  31 R is shorter than a length L 1  from the mesh body  32  to the downstream end portion of the flavor source container  31 . In other words, the downstream end portion of the rib  31 R comes into contact with the filter  33  without reaching the downstream end portion of the flavor source container  31 . Accordingly, a function of positioning the filter  33  can be achieved while reinforcing the flavor source container  31  using the rib  31 R. 
     First Modification 
     A first modification of the embodiment will be described below. Differences from the embodiment are mainly described below. 
     Specifically, in the embodiment, the flavor source container  31  has the protruding portion  31 E (first protruding portion) as a spacer that forms the aerosol flow adjustment chamber G. Conversely, in the first modification, the flavor source container  31  does not have the protruding portion  31 E. 
       FIG. 19  is a diagram illustrating a connection state of the first cartridge  20  and the second cartridge  30  according to the first modification. However, it should be noted that in  FIG. 19 , the reservoir  21 , the atomizer  22 , the flavor source  31 A, the filter  33 , and the cap  34  are omitted. 
     As illustrated in  FIG. 19 , the flavor source container  31  has a main body portion  31 P that accommodates the flavor source  31 A and a flange portion  31 Q provided on the side surface of the main body portion  31 P. It should be noted that in the cross section orthogonal to the aerosol flow path (predetermined direction A), the flange portion  31 Q overhangs to the outside than the main body portion  31 P, and overhangs outside to the same degree or more as the inner surface of the outer frame  24 . In  FIG. 19 , the flange portion  31 Q is provided on the side surface of the downstream end portion of the main body portion  31 P, but is not limited thereto, and may be provided somewhere on the side surface of the main body portion  31 P in a mode of being locked to the inner surface of the outer frame  24 . 
     Here, a distance L 3  from the downstream end portion of the outer frame  24  to the end cap  25  (that is, a distance from a part in which the outer frame  24  abuts the flange portion  31 Q to the downstream end portion of the end cap  25 ) is longer than a length L 4  of the main body portion  31 P (that is, a distance from an upstream end portion of the flange portion  31 Q to the upstream end portion of the main body portion  31 P). Accordingly, the aerosol flow adjustment chamber G that adjusts the flow of aerosol supplied from first flow path  20 X is formed even if the flavor source container  31  does not have the protruding portion  31 E by the flange portion  31 Q catching on the downstream end portion of the outer frame  24 . 
     Note that, when the first cartridge  20  does not have the end cap  25 , a distance from the downstream end portion of the outer frame  24  to the downstream end portion of the flow path forming body  23  (that is, a distance from a part in which the outer frame  24  abuts the flange portion  31 Q to the downstream end portion of the flow path forming body  23 ) is longer than a length of the main body portion  31 P (that is, a distance from an upstream end portion of the flange portion  31 Q to the upstream end portion of the main body portion  31 P). 
     Second Modification 
     A second modification of the embodiment will be described below. Differences from the embodiment are mainly described below. 
     Specifically, in the embodiment, the flavor source container  31  has the protruding portion  31 E (first protruding portion) as a spacer that forms the aerosol flow adjustment chamber G. Conversely, in the second modification, the flavor source container  31  does not have the protruding portion  31 E. 
       FIG. 20  is a diagram illustrating a connection state of the first cartridge  20  and the second cartridge  30  according to the second modification. However, it should be noted that in  FIG. 20 , the reservoir  21 , the atomizer  22 , the flavor source  31 A, the filter  33 , and the cap  34  are omitted. The protruding portion  25 E contacts the upstream end portion of the flavor source container  31  (preferably, the outer edge of the upstream end portion). 
     As illustrated in  FIG. 20 , the end cap  25  has the protruding portion  25 E that protrudes from the outer edge of the downstream end portion of the end cap  25  to the downstream side (flavor source container  31  side) in the cross section orthogonal to the aerosol flow path (predetermined direction A). The protruding portion  25 E may be continuously provided along the outer edge of the end cap  25  and may be intermittently provided along the outer edge of the end cap  25 . Note that, when there is a gap between the outer frame  24  and the flavor source container  31 , preferably the protruding portion  25 E is continuously provided along the outer edge of the end cap  25 . Thereby, it is possible to suppress retention of aerosol in the gap formed in the upstream part of a taper part  31 T. 
     In this manner, the aerosol flow adjustment chamber G that adjusts the flow of the aerosol supplied from first flow path  20 X is formed even if the flavor source container  31  does not have the protruding portion  31 E by the protruding portion  25 E being provided in place of the protruding portion  31 E. 
     Note that, when the first cartridge  20  does not have the end cap  25 , the flow path forming body  23  has the same protruding portion as the protruding portion  25 E that protrudes from the outer edge of the downstream end portion of the flow path forming body  23  to the downstream side (flavor source container  31  side) in the cross section orthogonal to the aerosol flow path (predetermined direction A). 
     Third Modification 
     A third modification of the embodiment will be described below. Differences from the embodiment are mainly described below. 
     Specifically, in the embodiment, the first flow path  20 X completely overlaps the second flow path  30 X viewed from the predetermined direction A. In addition, in the cross section orthogonal to the aerosol flow path (predetermined direction A), preferably the size of the second flow path  30 X is larger than the size of the first flow path  20 X. 
     In contrast, in the third modification, as illustrated in  FIG. 21 , viewed from the predetermined direction A, the first flow path  20 X is shifted from the second flow path  30 X without completely overlapping the second flow path  30 X. In such a case, in the cross section orthogonal to the aerosol flow path (predetermined direction A), the size of the second flow path  30 X is not particularly limited, but may be to the same degree as the size of the first flow path  20 X, and may be smaller than the size of the first flow path  20 X. However, the size of the second flow path  30 X may be larger than the size of the first flow path  20 X. 
     Fourth Modification 
     Hereinafter, the fourth modification of the embodiment will be described with reference to  FIG. 22  to  FIG. 25 . Differences from the embodiment are mainly described below. In  FIG. 22  to  FIG. 25 , the vertical axis represents the aerosol amount (amount of total particulate matter (TPM)) (mg/puff action), and the horizontal axis represents the number of puff actions (puff number). The vertical axis and the horizontal axis represent larger values as it is away from the intersection point of both axes. 
     In the fourth modification, in the same manner as in the embodiment, the power controller  53  stops power supply from the battery  11  to the atomizer  22  when a predetermined period elapses from the start of power supply to the atomizer  22 . The predetermined period is shorter than an upper limit value of a standard puff period derived from statistics of puff periods of users. 
     Note that, the aerosol amount atomized by the atomizer  22  depends on the puff period in which the puff action is actually performed by the user and the output voltage output to the battery  11 . Here, the explanation may be given assuming that the standard puff period derived from statistics of the puff period of the user may be considered as following a normal distribution having an average of 2.4 seconds and a standard deviation of 1 second. Note that, in such a case, as described above, the upper limit value of the standard puff period is derived as m+no (here, m is the average value, σ is standard deviation, and n is a positive real number), and for example, is to the degree of three to four seconds. Here, description is made assuming a case in which the upper limit value of the standard puff period is three seconds (n=0.6). 
     In sample E, an initial value of the output voltage of the battery  11  is 4.2 V, and the battery capacity of the battery  11  is 220 mAh. In addition, the atomizer  22  is constituted by the heating wire wound around, and the resistance value of the heating wire is 3.5Ω. In  FIG. 22 , a sample E 1  indicates a relationship between the number of puffs and the aerosol amount when sample E is inhaled in the puff period of two seconds per one puff action, and a sample E 2  indicates the relationship between the number of puffs and the aerosol amount when sample E is inhaled in the puff period of three seconds per one puff action. Here, it should be noted that when the standard puff period follows an average of 2.4 seconds and normal distribution of the standard deviation of one second, probability of inhaling in the puff period of three seconds or more per one puff action as indicated in sample E 2  is approximately 27%, and is a circumstance that sufficiently occurs. 
     In sample F, the configuration of the battery  11  and the atomizer  22  is the same as the sample E. In  FIG. 23 , a sample F 1  indicates a relationship between the number of puffs and the aerosol amount when sample F is inhaled in the puff period of two seconds per one puff action, and a sample F 2  indicates the relationship between the number of puffs and the aerosol amount when sample F is inhaled in the puff period of three seconds per one puff action. However, in the sample F 1  and the sample F 2 , the power controller  53  stops power supply from the battery  11  to the atomizer  22  when a predetermined period elapse from the start of power supply to the atomizer  22  (here, 2.2 seconds). Here, it should be noted that the predetermined period is 2.2 seconds that is shorter than the upper limit value of the standard puff period derived from statistics of the puff period of the user, and is shorter than the average value of the puff period. 
     In a sample G, the configuration of the battery  11  is the same as the samples E and F. Meanwhile, the atomizer  22  is constituted by the heating wire wound at a predetermined pitch, and is different from samples E and F in that the resistance value of the heating wire is 2.9Ω. In  FIG. 24 , a sample G 1  indicates a relationship between the number of puffs and the aerosol amount when the sample G is inhaled in the puff period of two seconds per one puff action, and a sample G 2  indicates the relationship between the number of puffs and the aerosol amount when the sample G is inhaled in the puff period of three seconds per one puff action. However, in the sample G 1  and the sample G 2 , the power controller  53  stops power supply from the battery  11  to the atomizer  22  when a predetermined period elapse from the start of power supply to the atomizer  22  (here, 2.2 seconds). 
     In a sample H, the configuration of the battery  11  and the atomizer  22  is the same as the sample G. However, the predetermined pitch of the heating wire forming the atomizer  22  is uniformly wound in a range of from 0.35 to 0.40 mm, and is narrower than the predetermined pitch of the sample G. In  FIG. 25 , a sample H 1  indicates a relationship between the number of puffs and the aerosol amount when the sample H is inhaled in the puff period of two seconds per one puff action, and a sample H 2  indicates the relationship between the number of puffs and the aerosol amount when the sample H is inhaled in the puff period of three seconds per one puff action. In addition, in the sample H 1  and the sample H 2 , in the same manner as the sample G, the power controller  53  stops power supply from the battery  11  to the atomizer  22  when a predetermined period elapse from the start of power supply to the atomizer  22  (here, 2.2 seconds). However, in the sample H 1  and the sample H 2 , the duty ratio is modified during power supply to the atomizer  22  according to the value of the output voltage of the battery  11  detected by the detector  51 . Specifically, as described above, since the output voltage of the battery  11  lowers accompanying reduction of the accumulated amount in the battery  11 , the duty ratio of the power supplied to the atomizer  22  is increased according to lowering of the output voltage of the battery  11 . 
     Under such premises, as illustrated in  FIG. 22 , the sample E in which the puff period and the energization time to the atomizer  22  match regardless of the length of the puff period is modified such that the aerosol amount is large when the puff period is three seconds and when the puff period is two seconds. In addition, as understood by comparing inclination of the sample E 1  and the sample E 2 , variation of the aerosol amount from the initial puff up to the final puff is more remarkable the longer the puff period, that is, the energization time. 
     Focusing on such results, an inventor and the like found that when the predetermined period is set shorter than the upper limit value of the standard puff period derived from statistics of the puff period of the user and the predetermined period elapses from the start of power supply to the atomizer  22  in one puff action, as illustrated in  FIG. 23 , it is possible to suppress variation of the aerosol amount from the initial puff up to the final puff even in the sample F 2  in which the puff period is three seconds by stopping power supply from the battery  11  to the atomizer  22 . Thereby, it is possible to suppress variation of the aerosol amount because of variation of the puff period of the user. 
     Furthermore, focusing on such results, as illustrated in  FIG. 24 , the inventor and the like found that it is possible for the aerosol amount atomized by the atomizer  22  falls within the desired range across the number of longer puffs from the initial puff to the final puff by modifying the configuration of the atomizer  22  such that the aerosol amount atomized by the atomizer  22  falls within the desired range when the energization time of the atomizer  22  is the predetermined period. Here, comparing the sample G 2  illustrated in  FIG. 24  and the sample F 2  illustrated in  FIG. 23 , in the sample G 2 , the aerosol amount atomized by the atomizer  22  falls within the desired range across the number of puffs that are longer than the sample F 2 , whereas a fluctuation range of the aerosol amount from the initial puff to the final puff is increased more than the fluctuation range in the sample F 2 . Thereby, the amount of power supply from the battery  11  to the atomizer  22  increases in one puff action by modifying the configuration of the atomizer  22 . 
     Furthermore, focusing on such results, the inventor and the like found that it is possible to mitigate a reduction rate of the aerosol amount by carrying out the following modifications. Specifically, it is possible to mitigate the reduction rate of the aerosol amount by increasing the duty ratio of the power supplied to the atomizer  22  in response to lowering of the output voltage of the battery  11 . In addition, it is possible to mitigate the reduction rate of the aerosol amount even if the predetermined pitch of the heating wire is narrow. As illustrated in  FIG. 25 , by such a modification, it was found that the aerosol amount atomized by the atomizer  22  falls within the desired range across the entire period from the initial puff to the final puff in either of H 1  in which the puff period is two seconds and H 2  in which the puff period is three seconds. 
     Based on these results, the inventor and the like newly found that it is effective to perform control as indicated below on the power supply from the battery  11  to the atomizer  22 . 
     (1) The power controller  53  stops power supply from the battery  11  to the atomizer  22  when a predetermined period elapses from the start of power supply to the atomizer  22 . Here, preferably the predetermined period is shorter than the upper limit value of the standard puff period derived from statistics of the puff period of the user, and is shorter than the average value of the puff period. 
     (2) The resistance value of the heating wire of the atomizer  22  is determined such that the aerosol amount in the desired range is atomized when the energization time of the atomizer  22  is the predetermined period. Here, preferably the resistance value of the heating wire is determined such that the voltage supplied from the battery  11  to the atomizer  22  is set as the voltage in the final stage in which the accumulated amount in the battery  11  is insufficient and the aerosol amount atomized by the atomizer  22  falls within the desired range when the energization time of the atomizer  22  is the predetermined period. 
     (3) Furthermore, the power controller  53  increases the duty ratio of power supplied to the atomizer  22  in response to a reduction of the output voltage of the battery  11  such that the aerosol amount atomized by the atomizer  22  falls within the desired range across the entire period from the initial puff to the final puff. 
     By the control described above, regardless of the length of the puff period of the user, it is possible to suppress a difference of the amount of power actually supplied from the battery  11  to the atomizer  22 , through the initial step, in which the accumulated amount in the battery  11  is sufficient, to the final step, in which the accumulated amount in the battery  11  is insufficient, and it is easy for the aerosol amount to fall within the desired range. 
     That is, in the fourth modification, the atomizer  22  is configured to be capable of atomizing the aerosol of a larger amount than the desired range of the amount of supply of the aerosol in one puff action at the start of use of at least the atomizer  22  (in other words, while the battery  11  is fully charged) by adjusting the predetermined pitch of the heating wire forming the atomizer  22  and the resistance value. 
     Under such premises, the predetermined instruction (here, duty ratio) output from the power controller  53  is determined based on the length of the predetermined period such that the aerosol amount atomized by the atomizer  22  in the predetermined period falls within the desired range. In other words, the predetermined instruction is determined based on the length of the predetermined period in a state in which variance of the aerosol amount caused by the variance of the length of the puff period of the user is suppressed by determining the predetermined period. Accordingly, it is possible for the aerosol amount to easily fall in the desired range regardless of the length of the puff period of the user from the initial step (start of smoking) in which the accumulated amount in the battery  11  is sufficient up to the final step (end of smoking) in which the accumulated amount in the battery  11  is insufficient. 
     In the fourth modification, preferably the upper limit of the aerosol amount (desired range) atomized by the atomizer  22  is 4.0 mg per one puff action. Furthermore, preferably the upper limit is 3.0 mg per one puff action. Deterioration of the raw material pieces included in the flavor source  31 A accommodated in the second cartridge  30  is suppressed by the value described above being the upper limit. 
     Meanwhile, preferably the lower limit of the aerosol amount (desired range) atomized by the atomizer  22  is 0.1 mg per one puff action. By setting the value described above to the lower limit, it is possible to supply the aerosol to the user at an amount that does not impart a sense of shortage, and it is possible to remove the flavor component from the flavor source  31 A accommodated in the second cartridge  30  using the aerosol. 
     Fifth Modification 
     A fifth modification of the embodiment will be described below. Differences from the embodiment are mainly described below. 
     In the embodiment described above, the predetermined period is determined according to the standard puff period derived from statistics of the puff periods of the plurality of users. In contrast, in the fifth modification, the predetermined period is derived from statistics of the puff period of the user who actually uses the non-burning type flavor inhaler  1 . 
       FIG. 26  is a diagram mainly illustrating a function block of the control circuit  50  according to the fifth modification. In  FIG. 26 , the same reference numerals are given to the same configuration as in  FIG. 15 , and description of the same configuration as in  FIG. 15  is omitted. 
     As illustrated in  FIG. 26 , the control circuit  50  has a memory  54  and a calculator  55  in addition to the configuration illustrated in  FIG. 15 . 
     The memory  54  stores the puff period that is a period in which the user performs the puff action. 
     The calculator  55  calculates the predetermined period described above from statistics of the puff period stored in the memory  54 . That is, the predetermined period is derived from statistics of the puff period stored in the memory  54 . However, it should be noted that the predetermined period is shorter than the upper limit of the standard puff period described above. 
     For example, the calculator  55  operates the predetermined period in the following procedures. 
     Firstly, in the same manner as in the embodiment described above, in the initial setting, the predetermined period (I seconds) is determined in advance according to the standard puff period derived from statistics of the puff periods of the plurality of users. 
     Secondly, for example, the average value is derived from statistics of the puff period detected in a fixed period (for example, from the start of use of the first cartridge  20  up to replacement of the first cartridge  20 ). 
     Thirdly, the predetermined period is modified to the average value (X seconds). 
     Fourthly, the duty ratio is modified such that the amount of power supply to the atomizer  22  during inhaling for X seconds is equal to the amount of power supply during initial setting (during inhaling for I seconds). That is, when the average value (X)&lt;initial setting value (I), the duty ratio that corresponds to each battery voltage is relatively increased. Meanwhile, when the average value (X)&gt;initial setting value (I), the duty ratio is reduced. 
     Note that, preferably for example, the predetermined period is recalculated in each fixed period (for example, replacement of the first cartridge  20 ). 
     (Operation and Effect) 
     In the fifth modification, the predetermined period is derived from statistics of the puff period of the user who actually uses the non-burning type flavor inhaler  1 . Accordingly, it is possible to set a period appropriate to the user as the predetermined period referenced when stopping the power supply from the battery  11  to the atomizer  22 . More particularly, it is possible to mitigate discomfort because of supply of the aerosol across the entirety of the puff period applied to the user who has a long puff period, and it is possible to increase the number of puff actions in which aerosol is supplied in the desired range to a user who has a short puff period compared to a case in which the predetermined period derived from statistics of the puff periods of a plurality of users is used by setting the predetermined period appropriate in the actual puff period of the user. 
     Sixth Modification 
     A sixth modification of the embodiment will be described below. Differences from the embodiment are mainly described below. 
     In the embodiment described above, the predetermined period is determined according to the standard puff period derived from statistics of the puff periods of the plurality of users. In contrast, in the sixth modification, the predetermined period is derived from statistics of the puff period of the user who actually uses the non-burning type flavor inhaler  1 . 
       FIG. 27  is a diagram mainly illustrating a function block of the control circuit  50  according to the sixth modification. In  FIG. 27 , the same reference numerals are given to the same configuration as in  FIG. 15 , and description of the same configuration as in  FIG. 15  is omitted. 
     As illustrated in  FIG. 27 , the control circuit  50  has a memory  54  and an interface  56  in addition to the configuration illustrated in  FIG. 15 . 
     The memory  54  stores the puff period a period in which the user performs the puff action. 
     The interface  56  is an interface for communicating with an external device  200  provided separately from the non-burning type flavor inhaler  1 . The interface  56  may be a USB port, may be a wired LAN module, may be a wireless LAN module, and may be a near field communication module (for example, Bluetooth or FeliCa). The external device  200  may be a personal computer, and may be a smartphone. 
     Specifically, the interface  56  transmits the puff period stored in the memory  54  to the external device  200 . The interface  56  receives the predetermined period calculated from statistics from the external device  200  based on the puff period using the external device  200 . 
     It should be noted that the external device  200  calculates the predetermined period using the same method as the calculator  55  according to the fifth modification. 
     (Operation and Effect) 
     In the sixth modification, the predetermined period is derived from statistics of the puff period of the user who actually uses the non-burning type flavor inhaler  1 . Accordingly, it is possible to set a period appropriate to the user as the predetermined period referenced when stopping the power supply from the battery  11  to the atomizer  22 . More particularly, it is possible to mitigate discomfort because of supply of the aerosol across the entirety of the puff period applied to the user who has a long puff period, and it is possible to increase the number of puff actions in which aerosol is supplied in the desired range to a user who has a short puff period compared to a case in which the predetermined period derived from statistics of the puff periods of a plurality of users is used by setting the predetermined period appropriate in the actual puff period of the user. 
     Seventh Modification 
     A seventh modification of the embodiment will be described below. Differences from the embodiment are mainly described below. 
     In the embodiment described above, the notification controller  52  has the counter  52 X that counts the number of puff actions or the energization time of the atomizer  22 . In contrast, in the seventh modification, as illustrated in  FIG. 28 , the notification controller  52  has a first counter  52 A and a second counter  52 B as the counter  52 X that counts the number of puff actions or the energization time of the atomizer  22 . 
     In the seventh modification, it should be noted that the lifespan of the first cartridge  20  is the lifespan of the second cartridge  30 ×T (T is an integer)+β. Note that, β is a value smaller than the lifespan of the second cartridge  30 , but is not particularly limited thereto. 
     The notification controller  52  detects the replacement timing of the second cartridge  30  when the count value of the first counter  52 A reaches a first predetermined value. The notification controller  52  detects the replacement timing of the first cartridge  20  when the count value of the second counter  52 B reaches a second predetermined value. The second predetermined value is an integral multiple of the first predetermined value. 
     Alternatively, when the count value of the first counter  52 A reaches a predetermined value P, the notification controller  52  may detect the replacement timing of the second cartridge  30  and increment the count value of the second counter  52 B. Thereby, the notification controller  52  may detect the replacement timing of the first cartridge  20  when the count value of the second counter  52 B reaches a predetermined value Q. That is, in the same manner as in the embodiment described above, the notification controller  52  may detect the replacement timing of the first cartridge  20  when the number of replacement times of the second cartridge  30  reaches a predetermined number of times (predetermined value Q). 
     In this manner, it should be noted that as a result of the second predetermined value being an integral multiple of the first predetermined value, the notification controller  52  detects the replacement timing of the first cartridge  20  based on the number of times of replacement of the second cartridge  30 . 
     In the seventh modification, when the count value of the first counter  52 A reaches the first predetermined value, the notification controller  52  may detect the replacement timing of the second cartridge  30  and reset the count value of the first counter  52 A. Alternatively, when the count value of the first counter  52 A reaches the first predetermined value, the notification controller  52  may detect the replacement timing of the second cartridge  30  and reset the count value of the first counter  52 A according to the predetermined operation of the user. In such a case, preferably the power controller  53  stops the power supply from the battery  11  to the atomizer  22  from the count value of the first counter  52 A reaching the first predetermined value until the count value is reset. 
     In the seventh modification, when the count value of the second counter  52 B reaches the second predetermined value, the notification controller  52  may detect the replacement timing of the first cartridge  20  and reset the count value of the second counter  52 B. Alternatively, when the count value of the second counter  52 B reaches the second predetermined value, the notification controller  52  may detect the replacement timing of the first cartridge  20  and reset the count value of the second counter  52 B according to the predetermined operation of the user. In such a case, preferably the power controller  53  stops the power supply from the battery  11  to the atomizer  22  from the count value of the second counter  52 B reaching the second predetermined value until the count value is reset. 
     (Operation and Effect) 
     In the seventh modification, it is possible to improve convenience for the user by notifying the replacement timing of the first cartridge  20  and the second cartridge  30  at the same timing even when replacement of the second cartridge  30  is repeated because the second predetermined value is an integral multiple of the first predetermined value. 
     Eighth Modification 
     An eighth modification of the embodiment will be described below. Differences from the embodiment are mainly described below. 
     In the eighth modification, a package provided with the first cartridge and the second cartridge is described.  FIG. 29  is a diagram illustrating a package  300  according to the eighth modification. 
     As described in  FIG. 29 , the package  300  has the first cartridge  20  and the second cartridge  30 . The number of second cartridges  30  is determined according to the lifespan of the first cartridge  20 . For example, the package  300  illustrated in  FIG. 29  has one first cartridge  20  and five second cartridges  30 . In other words, the number of second cartridges  30  is determined such that the lifespan of one first cartridge  20  comes to an end when five second cartridges  30  are used up. 
     Specifically, a permissible puff number that is the number of puff actions permissible for the first cartridge  20  or a permissible energization time that is the energization time permitted in the first cartridge  20  is determined for the first cartridge  20 . The number of permissible puffs and the permissible energization time are values for suppressing depletion of the aerosol source  21 A. In other words, the number of permissible puffs or the permissible energization time is upper limit value allows to atomize appropriate aerosol while stably supplying the aerosol source  21 A to the atomizer  22 . A timing at which the number of puff actions or the energization time of the atomizer  22  reaches the predetermined value is determined as the replacement timing of the second cartridge  30 . The number of second cartridges  30  is an integral part of a quotient in which the permissible puff number or the permissible energization time is divided by the predetermined value. Here, the permissible puff number or the permissible energization time may not be divided by the predetermined value. In other words, the lifespan of the first cartridge  20  may be a lifespan that has a margin with respect to the number of second cartridges  30 . 
     Alternatively, a timing at which the number of puff actions or the energization time of the atomizer  22  reaches the first predetermined value is the replacement timing of the second cartridge  30 . A timing at which the number of puff actions or the energization time of the atomizer  22  reaches the second predetermined value is the replacement timing of the first cartridge  20 . The second predetermined value is an integral multiple T of the first predetermined value. The integral multiple T is the number of the second cartridges  30  that are contained in the package  300 . 
     (Operation and Effect) 
     In the eighth modification, convenience for the user is improved since the replacement timing of the first cartridge  20  and the second cartridge  30  are aligned even when replacement of the second cartridge  30  is repeated since the number of second cartridges  30  is determined according to the lifespan of the first cartridge  20 . In other words, it is possible for the user to easily ascertain the replacement timing of the first cartridge  20  by using up the second cartridge  30  contained in the package  300 . 
     Ninth Modification 
     A ninth modification of the embodiment will be described below. Main differences from the embodiment are described below. 
     In the ninth modification, the power controller  53  carries out a detection process in which the replacement timing of the second cartridge  30  is detected when power supply from the battery  11  to the atomizer  22  is stopped. According to such a configuration, power supply from the battery  11  to the atomizer  22  is continuous even when an original timing at which the second cartridge  30  is to be replaced (for example, a timing at which an energization time to the atomizer  22  reaches the predetermined value) is included in the way of the puff action. In comparison to a case in which power supply from the battery  11  to the atomizer  22  is forcibly stopped at the original timing at which the second cartridge  30  is to be replaced, aerosol of a desired amount is able to be supplied in the final puff action and it is possible to mitigate discomfort imparted to the user. 
     In such a case, preferably the power controller  53  carries out the detection process from stopping of power supply from the battery  11  to the atomizer  22  until a determination period has elapsed. Here, preferably the determination period is a period that is assumed to be shorter than a period from the end of a current puff action until a subsequent puff action starts. As the determination period, for example, it is possible to use a period such as three seconds or one second. According to such a configuration, a circumstance is suppressed in which a possibility that the detection process is carried out until the subsequent puff starts is high and aerosol of the desired amount is not supplied in the subsequent puff action (final puff action). 
     In addition, preferably the notification controller  52  controls the notification unit  40  so as to notify the replacement timing of the second cartridge  30  from stopping of power supply from the battery  11  to the atomizer  22  until the determination period has elapsed (notification process) when the replacement timing of the second cartridge  30  is detected in the detection process. According to such a configuration, it is possible to prompt such that the possibility that the notification process is carried out up to the subsequent puff starting is high and the user does not start the subsequent puff action in which aerosol of the desired amount is not supplied. 
     However, preferably the power controller  53  carries out the detection process until power supply from the battery  11  to the atomizer  22  starts in response to the start of the puff action when the puff action starts from stopping of power supply from the battery  11  to the atomizer  22  until the detection process is carried out. In other words, preferably the power controller  53  carries out the detection process prior to resuming power supply from the battery  11  to the atomizer  22  in the subsequent puff action. According to such a configuration, at least a circumstance in which aerosol of the desired amount is not supplied in the subsequent puff action is suppressed. Note that, preferably the notification controller  52  carries out the notification process prior to resuming power supply from the battery  11  to the atomizer  22  in the subsequent puff action when the replacement timing of the second cartridge  30  is detected in the detection process. 
     (Control Method) 
     A control method according to the ninth modification will be described below.  FIG. 30  is a flowchart illustrating the control method according to the embodiment.  FIG. 30  is a flowchart illustrating the control method of the amount of power supplied from the battery  11  to the atomizer  22  in one puff action. 
     As illustrated in  FIG. 30 , in step S 110 , the non-burning type flavor inhaler  1  (that is, the control circuit  50 , hereinafter the same) determines whether or not the start of the puff action is detected. If a determination result is YES, the non-burning type flavor inhaler  1  transitions to a process of step S 120 . If a determination result is NO, the non-burning type flavor inhaler  1  is in a standby state. 
     In step S 120 , the non-burning type flavor inhaler  1  starts power supply to the atomizer  22 . In the same manner as in the embodiment, the non-burning type flavor inhaler  1  outputs to the battery  11  a predetermined instruction instructed to the battery  11  such that the aerosol amount atomized by the atomizer  22  falls in the desired range. 
     In step S 130 , the non-burning type flavor inhaler  1  determines whether or not the end of the puff action is detected. If a determination result is YES, the non-burning type flavor inhaler  1  transitions to a process of step S 140 . If a determination result is NO, the non-burning type flavor inhaler  1  is in a standby state. However, in the same manner as in the embodiment, the non-burning type flavor inhaler  1  may stop power supply to the atomizer  22  also in the puff period in which the puff action is actually performed by the user when the predetermined period from the start of power supply to the atomizer  22  has elapsed. 
     In step S 140 , the non-burning type flavor inhaler  1  stops power supply to the atomizer  22 . 
     In step S 150 , the non-burning type flavor inhaler  1  counts up the counter  52 X. In the same manner as in the embodiment, the counter  52 X may count the number of puff actions and may count the energization time of the atomizer  22 . 
     In step S 160 , the non-burning type flavor inhaler  1  determines whether or not the count value of the counter  52 X reaches the predetermined value. If a determination result is YES, the non-burning type flavor inhaler  1  transitions to a process of step S 170 . When the determination result is NO, the non-burning type flavor inhaler  1  returns to the process of step S 110 . 
     In step S 170 , the non-burning type flavor inhaler  1  carries out the end process. For example, the end process may be a process in which the replacement timing of the second cartridge  30  is notified from the notification unit  40  and may be a process in which the power source of the non-burning type flavor inhaler  1  is forcibly switched off. 
     As described above, in the flow illustrated in  FIG. 30 , preferably step S 150  (count up of the counter  52 X) and step S 160  (determination of whether or not a count value of the counter  52 X reaches the predetermined value) are performed from stopping of power supply from the battery  11  to the atomizer  22  until the determination period has elapsed. Preferably step S 160  (for example, a process in which the replacement timing of the second cartridge  30  is notified) is also performed from stopping of power supply from the battery  11  to the atomizer  22  until the determination period has elapsed. 
     Other Embodiments 
     The present invention is described through the above-described embodiments, but it should not be understood that this invention is limited to the statements and the drawings constituting a part of this disclosure. From this disclosure, various alternative embodiments, examples, and operational technologies will be obvious to those skilled in the art. 
     In the embodiment, the first cartridge  20  has the end cap  25 , but the embodiment is not limited thereto. For example, the first cartridge  20  may not have the end cap  25  when the reservoir  21  has a configuration (for example, a tank) in which it is possible to suppress leakage of the aerosol source  21 A. In such a case, the aerosol flow adjustment chamber G is formed between the downstream end portion of the flow path forming body  23  and the upstream end portion of the flavor source container  31 . 
     In the embodiment, the second cartridge  30  is accommodated in the first cartridge  20  (protruding portion  25 E), but the embodiment is not limited thereto. For example, the power source unit  10  may accommodate the first cartridge  20  and the second cartridge  30 . Alternatively, the first cartridge  20  and the second cartridge  30  may be connected at end surfaces to face each other. In such a case, for example, the first cartridge  20  and the second cartridge  30  are connected by screwing. 
     Although not particularly mentioned in the embodiment, preferably the end cap  25  is joined to the reservoir  21  to suppress refilling and the like of the aerosol source  21 A in the reservoir  21 . 
     In the embodiment, the end cap  25  has the protruding portion  25 E that protrudes from the outer edge of the end cap  25  to the downstream side (flavor source container  31  side) in the cross section orthogonal to the aerosol flow path (predetermined direction A). However, the embodiment is not limited thereto. Note that, when the end cap  25  is not provided, the flow path forming body  23  may have the protruding portion  25 E that protrudes from the outer edge of the flow path forming body  23  to the downstream side (flavor source container  31  side) in the cross section orthogonal to the aerosol flow path (predetermined direction A). The protruding portion  25 E contacts the upstream end portion of the flavor source container  31  (for example, the outer edge of the upstream end portion). 
     In the embodiment, a case is exemplified in which the atomizer  22  has a heating wire (coil) wound at a predetermined pitch. However, the embodiment is not limited thereto. The shape of the heating wire forming the atomizer  22  is arbitrary. 
     In the embodiment, a case is exemplified in which the atomizer  22  is configured by the heating wire. However, the embodiment is not limited thereto. The atomizer  22  may atomize the aerosol source  21 A using ultrasonic waves. 
     In the embodiment, the first cartridge  20  is replaceable. However, the embodiment is not limited thereto. Specifically, in place of the first cartridge  20 , an atomizing unit that has the reservoir  21  and the atomizer  22  may be provided in the non-burning type flavor inhaler  1 , and the atomizing unit may be a unit that is not replaced. 
     In the embodiment, the second cartridge  30  is replaceable. However, the embodiment is not limited thereto. Specifically, in place of the second cartridge  30 , the flavor source unit that has the flavor source  31 A may be provided in the non-burning type flavor inhaler  1 , and the flavor source unit may be a unit that is not replaced. However, the second cartridge  30  is not necessarily an essential feature. 
     In the embodiment, the first cartridge  20  and the second cartridge  30  are replaceable. However, the embodiment is not limited thereto. Specifically, a configuration having the first cartridge  20  and the second cartridge  30  may be provided in the non-burning type flavor inhaler  1 . 
     In the embodiment, the package  300  has one first cartridge  20 . However, the embodiment is not limited thereto. The package  300  may have two or more first cartridges  20 . 
     In the embodiment, the power controller  53  controls the amount of power supplied from the battery  11  to the atomizer  22  by pulse control. However, the embodiment is not limited thereto. The power controller  53  may control the output voltage of the battery  11 . In such a case, preferably the power controller  53  modifies (or corrects) the predetermined instruction such that the aerosol amount atomized by the atomizer  22  falls within the desired range accompanying the reduction of the accumulated amount in the battery  11 . Specifically, the power controller  53  may increase the instruction voltage output to the battery  11  accompanying the reduction of the accumulated amount in the battery  11  as the modification of the predetermined instruction. The modification (or correction) of the output voltage of the battery  11  is realized using, for example, a DC/DC converter. The DC/DC converter may be a step-down converter, or may be a boost converter. Note that, the power controller  53  may control both pulse control and output voltage such that the aerosol amount atomized by the atomizer  22  falls within the desired range. 
     In the embodiment, the power controller  53  increases the duty ratio output to the battery  11  in one puff action accompanying the reduction of the accumulated amount in the battery  11  as the modification of the predetermined instruction. However, the embodiment is not limited thereto. The power controller  53  may extend the predetermined period for stopping power supply from the battery  11  to the atomizer  22  accompanying the reduction of the accumulated amount in the battery  11  as the modification of the predetermined instruction. 
     In the embodiment, the detector  51  is connected to a voltage sensor provided on a sensor line that connects the battery  11  and the atomizer  22 , and detects power supply based on the output result of the voltage sensor. However, the embodiment is not limited thereto. For example, the detector  51  may be connected to a current sensor provided on the sensor line that connects the battery  11  and the atomizer  22 , and may detect power supply based on the output result of the current sensor. 
     In the embodiment, the power controller  53  instructs, to the battery  11 , output of power to the atomizer  22  in the puff period in which the puff action is performed, but does not instruct, to the battery  11 , output of power to the atomizer  22  in the non-puff period in which the puff action is not performed. However, the embodiment is not limited thereto. The power controller  53  may switch power output to the atomizer  22  according to the operation of the hardware interface (for example, the switch or the button) for performing power output to the atomizer  22 . That is, the puff action and the non-puff action are switched according to the operation of the hardware interface. 
     INDUSTRIAL APPLICABILITY 
     It is possible to provide a non-burning type flavor inhaler and a package that are able to improve convenience for the user by notifying to the user a replacement timing of a first cartridge or a replacement timing of a second cartridge.
