[Flavor suction system according to first embodiment]
FIG. 2 shows an example of the flavor suction system according to the first embodiment of the present invention. The flavor suction system shown in FIG. 2 includes a combustion type flavor suction device 1 and a heating device 10. The heating device 10 has a cylindrical housing 11 having a bottom. The housing 11 is made of a heat insulating material. The bottom of the housing 11 constitutes an ash receiver 14 capable of collecting ash generated during combustion of tobacco rods. A plurality of ring-shaped heaters 12 that can be heated independently are provided on the inner side surface of the housing 11. The ring-shaped heater 12 can be an electric heater. As shown in FIG. 2, the tobacco rod of the combustion type flavor inhaler 1 is arranged inside the plurality of ring-shaped heaters 12. Note that since FIG. 2 is schematically illustrated, there is a gap between the tobacco rod of the combustion-type flavor inhaler 1 and the ring-shaped heater 12, but from the viewpoint of more efficient heat transfer, Preferably, the tobacco rod is in contact with a plurality of ring-shaped heaters 12. Further, as will be described later, the ring-shaped heater 12 is a heater whose heating portion is movable toward the suction end (movable in direction A) as heating or combustion of the tobacco rod progresses. A thermally conductive fire spread prevention plate 13 that can come into contact with the tobacco rod when the combustion type flavor inhaler 1 is not in use is provided in the gap between each of the ring-shaped heaters 12 . The material of the fire spread prevention plate 13 is not particularly limited as long as it is a thermally conductive material, and examples thereof include metals such as aluminum and stainless steel, heat-resistant ceramics, and glass. A fixing member 15 is provided near the opening of the housing 11 to fix the combustion type flavor inhaler 1 by sandwiching the filter portion of the combustion type flavor inhaler 1. The heating device 10 also includes a switch (not shown) that can control heating on/off of the ring-shaped heater 12.

A user first inserts the combustion type flavor inhaler 1 into the casing 11 of the heating device 10. At this time, the tobacco rod portion of the combustion type flavor inhaler 1 is placed inside the ring-shaped heater 12. Further, the combustion type flavor inhaler 1 is fixed by the fixing member 15. When the user turns on the heating device 10, the ring-shaped heater 12 closest to the non-sucking end side (the ash receiver 14 side of the housing 11) of the combustion-type flavor inhaler 1 generates heat, and the combustion-type flavor inhaler 1 generates heat. Burn or heat the tip of the tobacco rod in device 1. For example, when burning a tobacco rod, the tip of the tobacco rod is first ignited, and the ignited portion advances in direction A in FIG. In FIG. 2, 17 indicates the ignited portion of the tobacco rod, and 16 indicates the carbonized portion of the tobacco rod after ignition. The advancing speed of the ignition portion 17 is measured in advance, and the plurality of ring-shaped heaters 12 are caused to generate heat at the same speed as the advancing speed. That is, after the first ring-shaped heater 12 closest to the non-sucking end side (the ash receiving part 14 side of the housing 11) of the combustion type flavor inhaler 1 is made to generate heat, the ring-shaped heater 12 is placed next to it in accordance with the traveling speed. The second ring-shaped heater 12 is made to generate heat, and the first ring-shaped heater 12 is made to stop generating heat. Thereafter, the third, fourth, etc. ring-shaped heaters 12 are sequentially made to generate heat in accordance with the traveling speed. In FIG. 2, the ring-shaped heater 12a corresponding to the ignition portion 17 is generating heat, and the other ring-shaped heaters 12 are not generating heat. In this way, by sequentially causing the ring-shaped heater 12 to generate heat in accordance with the traveling speed, the tobacco rod can be efficiently burned. The same applies when the tobacco rod is heated rather than burned.

When the user completes use, all ring-shaped heaters 12 stop generating heat by turning off the heating device 10. At the same time, the fire spread prevention plate 13a located immediately after the ring-shaped heater 12a that was generating heat (the fire spread prevention plate adjacent to the ring-shaped heater 12a that was generating heat, and located on the suction end side) , is moved and pressed so as to come into contact with the tobacco rod. Since the fire spread prevention plate 13a has thermal conductivity, it can release heat from the ignited portion 17 of the tobacco rod and not only extinguish the fire but also prevent the spread of the fire. Even when the tobacco rod is heated rather than burned, the heat of the heated portion 17 can be released to lower the temperature. In this way, in this embodiment, the fire can be extinguished when not in use and the spread of the fire can be prevented, so that the generation of sidestream smoke can be significantly reduced when not in use. Furthermore, since the igniting portion 17 does not advance naturally when not in use, wear of the tobacco rod due to natural combustion when not in use can be suppressed, and the total number of puffs per tobacco rod can be increased.

When the user resumes use, by turning on the switch of the heating device 10 again, the fire spread prevention plate 13a is separated from the tobacco rod, and the ring-shaped heater 12a, which was generating heat when the switch was turned off, is removed. , fever resumes. In this embodiment, the flavor can be freely changed by changing the heating temperature by the ring-shaped heater 12a. Further, the carbonized portion 16 can be stored in the ash receiving portion 14 as ash. In the flavor suction system according to this embodiment, the heat generation of the ring-shaped heater 12 is controlled by a switch, but for example, a suction sensor (differential pressure gauge, anemometer, etc.) is provided near the opening of the housing 11 to control the suction. The ring-shaped heater 12 may be heated by sensing. The same applies to the flavor suction system according to the second embodiment described below.

[Flavor suction system according to second embodiment]
An example of a flavor suction system according to a second embodiment of the present invention is shown in FIG. The flavor suction system shown in FIG. 3 includes a combustion type flavor suction device 1 and a heating device 20. The heating device 20 has a cylindrical housing 21 having a bottom. The housing 21 is made of a heat insulating material. The bottom of the housing 21 constitutes an ash receiver 24 capable of collecting ash generated during combustion of tobacco rods. The heating device 20 includes a planar heater 22 whose heating portion has a planar shape. The planar heater 22 can be an electric heater. The heating portion of the sheet heater 22 is arranged so as to be able to come into contact with the tip of the tobacco rod. The planar heater 22 is connected to the bottom of the casing 21, and includes a drive section 23 that can move the planar heater 22 toward the mouth end (moveable in direction A) as the tobacco rod burns. Connected. The drive unit 23 can be an actuator, a spring, or the like. A fixing member 26 is provided near the opening of the housing 21 to fix the combustion type flavor inhaler 1 by sandwiching the filter portion of the combustion type flavor inhaler 1. The heating device 20 also includes a switch (not shown) that can control heating on/off of the sheet heater 22.

A user first inserts the combustion type flavor inhaler 1 into the casing 21 of the heating device 20. At this time, the tip of the tobacco rod of the combustion type flavor inhaler 1 is brought into contact with the planar heater 22. Further, the combustion type flavor inhaler 1 is fixed by the fixing member 26. When the user turns on the heating device 20, the sheet heater 22 generates heat and the tip of the tobacco rod ignites. The ignition portion 25 advances in the direction of travel A in FIG. Here, the ignited part 25 that has finished burning is carbonized, but the planar heater 22 is moved in the traveling direction A by the driving part 23 at the same speed as the advancing speed of the ignited part 25, and is pressed against the tip of the tobacco rod. Therefore, the carbonized portion falls as ash and is stored in the ash receiver 24. Then, the tip portion of the tobacco rod is heated by the planar heater 22 while removing the carbonized portion. In this manner, by moving and pressing the sheet heater 22 in accordance with the advancing speed of the ignition portion 25, the tobacco rod can be efficiently burned while removing the carbonized portion.

When the user completes use, the sheet heater 22 stops generating heat by turning off the heating device 20. Since the sheet heater 22 is pressed against the tip of the tobacco rod even after the heat generation has stopped, it is possible to release the heat of the ignited part 25 and not only extinguish the fire but also prevent the spread of the fire. In this way, in this embodiment, the fire can be extinguished when not in use and the spread of the fire can be prevented, so that the generation of sidestream smoke can be significantly reduced when not in use. Furthermore, since the igniting portion 25 does not advance naturally when not in use, wear of the tobacco rod due to natural combustion when not in use can be suppressed, and the total number of puffs per tobacco rod can be increased.

When the user resumes use, the sheet heater 22 resumes generating heat by turning on the heating device 20 again. In this embodiment, by changing the heating temperature by the planar heater 22, the flavor can be freely changed.

Another example of the flavor suction system according to the second embodiment of the present invention is shown in FIG. 4. The flavor suction system shown in FIG. 4 is similar to the flavor suction system shown in FIG. 3, except that the heating part of the planar heater 22 includes a needle part 27 into which a tobacco rod can be pierced. In the flavor suction system shown in FIG. 4, the sheet heater 22 is moved in the traveling direction A by the drive unit 23 while piercing the tobacco rod with the needle unit 27. Thereby, the tobacco rod can be heated efficiently. Moreover, the carbonized portion of the tobacco rod can be efficiently dropped into the ash receiving portion 24 as ash and stored therein. Note that the needle portion 27 may be a blade-shaped blade portion.

[Flavor suction system according to third embodiment]
An example of a flavor suction system according to a third embodiment of the present invention is shown in FIG. The flavor suction system shown in FIG. 5 is the same as the flavor suction system according to the second embodiment shown in FIG. This is similar to the flavor suction system according to the second embodiment shown in No. 3. The needle-shaped heater 28 may be a blade-shaped heater. In the flavor suction system shown in FIG. 5, the needle-shaped heater 28 is moved in the traveling direction A by the drive unit 23 while piercing and heating the tobacco rod with the needle-shaped heater 28. Thereby, the tobacco rod can be heated efficiently. Moreover, the carbonized portion of the tobacco rod can be efficiently dropped into the ash receiving portion 24 as ash and stored therein. The surface of the tip portion (needle portion) of the needle heater 28 may be unprocessed or may be processed into a drill shape. The thickness of the needle-shaped heater 28 is about the same as the thickness of the combustion type flavor inhaler 1, so that the tobacco rod can be heated as a whole, and the carbonized portion of the tobacco rod can be more efficiently turned into ash and sent to the ash receiver 24. This is preferable because it can be dropped. The thickness of the needle-shaped heater 28 can be, for example, 5 to 10 mm.

Hereinafter, specific examples of this embodiment will be described, but the present invention is not limited thereto.

[Example 1]
A flavor suction system shown in FIG. 2 was prepared. First, a commercially available combustion type flavor inhaler (cigarette) was prepared as the combustion type flavor inhaler 1. Further, as the heating device 10, a heating device 10 including a ring-shaped heater 12 with an inner diameter of 9.1 mm was prepared. Using the flavor suction system, a suction test was conducted using a piston-type suction device ("RM 26" manufactured by Borgwaldt) under conditions of a flow rate of 27.5 ml/sec and a suction time of 2 seconds/time. First, when the tip of the tobacco rod of the combustion-type flavor inhaler 1 was ignited with a lighter and inhaled, it was confirmed that the combustion distance per puff (2 seconds) was 3 mm on average. From this, the moving speed of the heater that generates heat was defined on the assumption that combustion progresses by 3 mm with one puff (2 seconds). The combustion type flavor inhaler 1 was inserted into the housing 11 of the heating device 10. At this time, a gap existed between the ring-shaped heater 12 and the tobacco rod of the combustion type flavor inhaler 1. The combustion type flavor inhaler 1 was fixed by the fixing member 15, and the heating device 10 was turned on. The heating temperature of the ring-shaped heater 12 was 800°C, 500°C, or 300°C. When the heating temperature was 800°C or 500°C, the tobacco rod was burned, and when the heating temperature was 300°C, the tobacco rod was heated without burning. When one puff was made by the suction device after combustion or heating, the switch was turned off, the heat generation of the ring-shaped heater 12a was stopped, and the fire spread prevention plate 13a was moved and pressed so as to come into contact with the tobacco rod. At this time, we checked to see if sidestream smoke was occurring between the puffs. 30 seconds after turning off the switch, turn on the switch again, separate the fire spread prevention plate 13a from the tobacco rod, restart heat generation from the ring-shaped heater 12a that was generating heat when the switch was turned off, and combustion or After heating, one puff was applied using an aspirator. This was repeated until the combustion type flavor inhaler 1 was completely used, and the total number of puffs was measured and the flavor was evaluated. The results are shown in Table 1.

[Example 2]
Example 1 was carried out in the same manner as in Example 1, except that the inner diameter of the ring-shaped heater 12 was changed to 7.5 mm so that the ring-shaped heater 12 and the tobacco rod of the combustion-type flavor inhaler 1 came into contact with each other. The results are shown in Table 1.

[Example 3]
A flavor suction system shown in FIG. 3 was prepared. As the combustion type flavor inhaler 1, the same combustion type flavor inhaler (cigarette) as in Example 1 was used. A suction test was conducted using the same suction device as in Example 1 under the same conditions as in Example 1. In this example as well, the moving speed of the planar heater 22 by the drive unit 23 was defined on the assumption that combustion progresses by 3 mm with one puff (2 seconds). The combustion type flavor inhaler 1 was inserted into the casing 21 of the heating device 20 so that the tip of the tobacco rod came into contact with the planar heater 22. The combustion type flavor inhaler 1 was fixed by the fixing member 26, the heating device 20 was turned on, and the planar heater 22 was made to generate heat. The heating temperature of the planar heater 22 was 800°C, 500°C, or 300°C. When the heating temperature was 800°C or 500°C, the tobacco rod was burned, and when the heating temperature was 300°C, the tobacco rod was heated without burning. After one puff was made by the suction device after combustion or heating, the switch was turned off and the heat generation of the sheet heater 22 was stopped. At this time, we checked to see if sidestream smoke was occurring between the puffs. Thirty seconds after turning off the switch, the switch was turned on again to resume heat generation by the planar heater 22, and after combustion or heating, one puff was made with the suction device. This was repeated until the combustion type flavor inhaler 1 was completely used, and the total number of puffs was measured and the flavor was evaluated. The results are shown in Table 1.

[Comparative example 1]
As the combustion type flavor inhaler 1, the same combustion type flavor inhaler (cigarette) as in Example 1 was used, and the tip of the tobacco rod was ignited using a lighter. A suction test was conducted using the same suction device as in Example 1 under the same conditions as in Example 1. After burning and taking one puff with the aspirator, the flame was not extinguished and waited for 30 seconds, and then one puff was taken again with the aspirator. This was repeated until all combustion-type flavor inhalers 1 were used, and the total number of puffs was measured and the flavor was evaluated. The results are shown in Table 1.

As shown in Table 1, in the flavor suction systems of Examples 1 to 3, by changing the heating temperature, the flavor obtained with the high-temperature heating type non-combustion heated flavor suction device and the flavor obtained with the combustion type flavor suction device can be improved. Both flavors were obtained. Specifically, by controlling the heating temperature to 800° C. or 500° C., a flavor equivalent to that of lighter heating in Comparative Example 1 (flavor obtained with a combustion-type flavor inhaler) was obtained. On the other hand, by controlling the heating temperature to 300° C., a flavor equivalent to that obtained with a high-temperature heating non-combustion heating flavor inhaler was obtained.

Furthermore, in the flavor suction systems of Examples 1 to 3, the fire was extinguished at the end of each puff, preventing the spread of the fire, so there was no generation of sidestream smoke between the puffs. On the other hand, in Comparative Example 1, the fire was not extinguished at the end of each puff, and sidestream smoke was generated due to spontaneous combustion between the puffs. In addition, in the flavor suction systems of Examples 1 to 3, the fire was extinguished at the end of each puff and the spread of the fire was prevented, so consumption of the tobacco rod when not in use was suppressed, and the total number of puffs was increased. On the other hand, in Comparative Example 1, the fire was not extinguished at the end of each puff, and the tobacco rod was consumed due to natural combustion between puffs, resulting in a small total number of puffs. In Example 3, when the heating temperature was 300° C., the tobacco rod did not burn, the tobacco rod was not carbonized, and the sheet heater 22 could not be pushed forward, so the total number of puffs was one.
