　以下、加熱式たばこ用ヒータ１０およびこれを備えた加熱式たばこ装置１００の一例について図面を参照して説明する。 Hereinafter, an example of the heating type tobacco heater 10 and the heating type tobacco device 100 including the heating type heater 10 will be described with reference to the drawings.
　本開示の加熱式たばこ用ヒータ１０は、図１に示すように、基体１と、発熱抵抗体２と、フランジ４と、接続端子３と、を有している。 The heating type tobacco heater 10 of the present disclosure has a base body 1, a heating resistor 2, a flange 4, and a connection terminal 3, as shown in FIG. 1.
　基体１は、発熱抵抗体２を保護する部材である。基体１は、長手方向を有する部材である。基体１は、例えば棒状、板状または筒状の部材である。基体１は、例えば先端が尖った形状であってもよい。基体１は、例えば中空の筒状部と、筒状部の一方の開口を塞ぐ先端部とを有していてもよい。この場合は、基体１の熱容量を低減できる。そのため、発熱抵抗体２で生じた熱を効果的に被加熱物であるたばこに伝えることができる。基体１は、絶縁性を有する部材である。基体１は、例えば樹脂材料またはセラミック材料等を有する。基体１は、セラミック材料を有する場合は、例えば酸化アルミニウム、窒化珪素または酸化ジルコニウムを用いることができる。 The base 1 is a member that protects the heating resistor 2. The base body 1 is a member having a longitudinal direction. The base 1 is, for example, a rod-shaped, plate-shaped, or tubular member. The base 1 may have a shape with a sharp tip, for example. The base 1 may have, for example, a hollow tubular portion and a tip portion that closes one opening of the tubular portion. In this case, the heat capacity of the base 1 can be reduced. Therefore, the heat generated in the heating resistor 2 can be effectively transferred to the tobacco, which is the object to be heated. The base 1 is a member having an insulating property. The base 1 has, for example, a resin material or a ceramic material. When the base 1 has a ceramic material, for example, aluminum oxide, silicon nitride or zirconium oxide can be used.
　基体１の寸法は、例えば基体１が板状の場合は、主面の形状が長方形であるときに、長辺の長さを５～２０ｍｍに、短辺の長さを１～１０ｍｍに、厚さを０．０８～１ｍｍにすることができる。また、基体１は、先端または全体が反ってもよい。 The dimensions of the base 1 are, for example, in the case where the base 1 is plate-shaped, the length of the long side is 5 to 20 mm, the length of the short side is 1 to 10 mm, and the thickness is 1 to 10 mm when the main surface has a rectangular shape. The height can be 0.08 to 1 mm. Further, the base 1 may be warped at the tip or the whole.
　また、基体１が筒状である場合は、長手方向の長さを５～２０ｍｍに、内径を８～２０ｍｍに、外径を８．５～２２ｍｍにすることができる。 If the base 1 is tubular, the length in the longitudinal direction can be 5 to 20 mm, the inner diameter can be 8 to 20 mm, and the outer diameter can be 8.5 to 22 mm.
　発熱抵抗体２は、被加熱物を加熱するための部材である。発熱抵抗体２は、例えば基体１の表面または内部に設けられている。発熱抵抗体２は、例えば線状または帯状の部材である。発熱抵抗体２は、例えば折返し部を有している。発熱抵抗体２は、外部電源に電気的に接続されている。発熱抵抗体２は、電流が流れることによって発熱し、被加熱物であるタバコを加熱することができる。発熱抵抗体２は、基体１の長手方向に沿って設けられていてもよい。 The heating resistor 2 is a member for heating an object to be heated. The heating resistor 2 is provided, for example, on the surface or inside of the base 1. The heating resistor 2 is, for example, a linear or strip-shaped member. The heating resistor 2 has, for example, a folded portion. The heating resistor 2 is electrically connected to an external power supply. The heating resistor 2 generates heat when an electric current flows, and can heat a cigarette which is an object to be heated. The heating resistor 2 may be provided along the longitudinal direction of the base 1.
　発熱抵抗体２は、例えばタングステン、モリブデン、クロム、これらの炭化物または金、銀、パラジウム、白金等の金属からなる。また、発熱抵抗体２は、金属以外の成分として、アルミナまたは窒化ケイ素等を有していてもよい。発熱抵抗体２の寸法は、例えば長さが５～５０ｍｍ、幅が０．２～２ｍｍ、厚さが０．００５～０．１ｍｍである。 The heating resistor 2 is made of, for example, tungsten, molybdenum, chromium, a carbide thereof, or a metal such as gold, silver, palladium, platinum. Further, the heating resistor 2 may have alumina, silicon nitride, or the like as a component other than metal. The dimensions of the heating resistor 2 are, for example, 5 to 50 mm in length, 0.2 to 2 mm in width, and 0.005 to 0.1 mm in thickness.
　発熱抵抗体２は、基体１の先端から後端まで設けられていてもよい。また、発熱抵抗体２は、基体１の先端側で折り返し形状を有していてもよい。また、図３に示すように、発熱抵抗体２は、発熱部２１とリード部２２とを有してもよい。このときに、リード部２２は、発熱部２１よりも抵抗値を小さくすることができる。これにより、リード部２２における発熱量を低減することができる。このときに、基体１のうち発熱部２１が設けられた領域を加熱領域１１とし、基体１のうちリード部２２が設けられた領域を、非加熱領域１２とすることができる。加熱領域１１は、例えば基体１の先端から発熱部２１とリード部２２との境界までの領域である。 The heating resistor 2 may be provided from the front end to the rear end of the base body 1. Further, the heating resistor 2 may have a folded shape on the tip side of the base 1. Further, as shown in FIG. 3, the heating resistor 2 may include a heating portion 21 and a lead portion 22. At this time, the lead portion 22 can have a smaller resistance value than the heat generating portion 21. Thereby, the amount of heat generated in the lead portion 22 can be reduced. At this time, the region of the substrate 1 where the heat generating portion 21 is provided can be the heating region 11, and the region of the substrate 1 where the lead portion 22 is provided can be the non-heating region 12. The heating region 11 is, for example, a region from the tip of the base 1 to the boundary between the heat generating portion 21 and the lead portion 22.
　発熱抵抗体２は、例えば、基体１の後端側において、接続端子３に接続されていてもよい。接続端子３は、発熱抵抗体２に電力を供給するための部材である。接続端子３は、電源に直接的または間接的に接続されることによって、発熱抵抗体２に通電することができる。電源は、加熱式たばこ装置１００に一体となって形成されていてもよいし、別体であってもよい。接続端子３は、例えば線状の部材である。接続端子３は、例えばニッケルまたは銅等の部材からなる。 The heating resistor 2 may be connected to the connection terminal 3 on the rear end side of the base body 1, for example. The connection terminal 3 is a member for supplying electric power to the heating resistor 2. The connection terminal 3 can be energized to the heating resistor 2 by being directly or indirectly connected to a power source. The power source may be formed integrally with the heating tobacco device 100 or may be a separate body. The connection terminal 3 is, for example, a linear member. The connection terminal 3 is made of a member such as nickel or copper.
　フランジ４は、基体１を保持するための部材である。フランジ４は、例えば基体１の長手方向を囲むように設けられていてもよい。フランジ４は、例えばセラミック材料等からなる。フランジ４は、例えば熱伝導率の低い部材にすることができる。フランジ４は、例えば酸化アルミニウムまたは酸化ジルコニウムを用いることができる。 The flange 4 is a member for holding the base body 1. The flange 4 may be provided, for example, so as to surround the base 1 in the longitudinal direction. The flange 4 is made of, for example, a ceramic material. The flange 4 can be a member having low thermal conductivity, for example. For the flange 4, for example, aluminum oxide or zirconium oxide can be used.
　接続端子３は、基体１から離れる方向に伸びる部分を有している。ここで、「基体１から離れる方向」とは、例えば図１に示すように基体１の長手方向であってもよいし、基体１の長手方向に垂直な方向であってもよい。 The connection terminal 3 has a portion extending in a direction away from the base body 1. Here, the “direction away from the substrate 1” may be the longitudinal direction of the substrate 1 as shown in FIG. 1 or the direction perpendicular to the longitudinal direction of the substrate 1.
　本開示の加熱式たばこ用ヒータ１０においては、フランジ４は、接続端子３に固定されている。これにより、フランジ４に外力が加わった際に、フランジ４が固定されている接続端子３が変形することで、基体１に生じる応力を低減することができる。そのため、基体１が破損するおそれを低減することができる。その結果、加熱式たばこ用ヒータ１０の耐久性を高めることができる。 In the heating type tobacco heater 10 of the present disclosure, the flange 4 is fixed to the connection terminal 3. Thus, when an external force is applied to the flange 4, the connection terminal 3 to which the flange 4 is fixed is deformed, so that the stress generated in the base body 1 can be reduced. Therefore, it is possible to reduce the possibility that the base body 1 is damaged. As a result, the durability of the heating type tobacco heater 10 can be improved.
　また、接続端子３は、基体１よりも弾性率が小さい部材であってもよい。これにより、フランジ４に外力が加わった際に、接続端子３が効率的に変形することができる。そのため、より効率的に基体１に生じる応力を低減することができる。そのため、基体１が破損するおそれを低減することができる。加えて、基体１の弾性率が接続端子３よりも大きいことにより、基体１は外力により変形しないため、加熱式たばこを突き刺しやすくすることができる。その結果、ユーザーの利便性を高めることができる。 The connection terminal 3 may be a member having a smaller elastic modulus than the base body 1. This allows the connection terminal 3 to be efficiently deformed when an external force is applied to the flange 4. Therefore, the stress generated in the substrate 1 can be reduced more efficiently. Therefore, it is possible to reduce the possibility that the base body 1 is damaged. In addition, since the elastic modulus of the base body 1 is larger than that of the connection terminal 3, the base body 1 is not deformed by an external force, so that the heating type cigarette can be easily pierced. As a result, the convenience of the user can be improved.
　なお、接続端子３にフランジ４を固定する方法としては、例えばフランジ４に接続端子３を挿入できる貫通孔４４を設けて、セラミックスまたは樹脂等の接着剤で固定することができる。また、接続端子３は、接着剤を用いずに、フランジ４にはめ込まれて固定されていてもよい。 As a method of fixing the flange 4 to the connection terminal 3, for example, a through hole 44 into which the connection terminal 3 can be inserted is provided in the flange 4, and the connection terminal 3 can be fixed with an adhesive such as ceramics or resin. Further, the connection terminal 3 may be fitted and fixed to the flange 4 without using an adhesive.
　また、図２に示すように、フランジ４は、接続端子３に固定されて、長手方向に垂直な方向に伸びる第１部分４１と、第１部分４１に連続し、長手方向に伸びる第２部分４２と、第２部分４２に連続し、長手方向に垂直な方向に伸び、基体１に固定される第３部分４３と、を有していてもよい。これにより、フランジ４が接続端子３のうち第１部分４１にのみ固定されている場合と比較して、フランジ４とヒータとを強固に固定することができる。第１部分４１、第２部分４２および第３部分４３は一体に形成されていてもよいし、別々に形成されたものが接合されていてもよい。第１部分４１、第２部分４２および第３部分４３が別々に形成されたものである場合は、第１部分４１及び第３部分４３は円板状の部材、第２部分４２は円筒状の部材を用いることができる。 Further, as shown in FIG. 2, the flange 4 is fixed to the connection terminal 3 and has a first portion 41 extending in a direction perpendicular to the longitudinal direction, and a second portion continuous with the first portion 41 and extending in the longitudinal direction. 42 and a third portion 43 that is continuous with the second portion 42, extends in a direction perpendicular to the longitudinal direction, and is fixed to the base body 1. Thereby, as compared with the case where the flange 4 is fixed only to the first portion 41 of the connection terminal 3, the flange 4 and the heater can be firmly fixed. The 1st part 41, the 2nd part 42, and the 3rd part 43 may be formed integrally, and what was formed separately may be joined. When the first portion 41, the second portion 42, and the third portion 43 are formed separately, the first portion 41 and the third portion 43 are disc-shaped members, and the second portion 42 is a cylindrical member. Members can be used.
　さらに、第３部分４３の厚みは、第１部分４１の厚みよりも小さくてもよい。これにより、基体１の熱が第３部分４３に伝わりにくくすることができる。したがって、加熱式たばこ装置１００本体への熱の伝わりを抑制することができる。その結果、加熱式たばこ装置１００の使用時に、持ち手が熱くなるおそれを低減できる。また、厚みが大きい第１部分４１により、フランジ４とヒータとを強固に固定することができる。その結果、加熱式たばこ装置１００の耐久性を高めつつ、加熱式たばこ装置１００本体への熱の伝わりを抑制することができる。 Furthermore, the thickness of the third portion 43 may be smaller than the thickness of the first portion 41. This makes it difficult for the heat of the base body 1 to be transferred to the third portion 43. Therefore, it is possible to suppress the transfer of heat to the main body of the heating type tobacco device 100. As a result, it is possible to reduce the risk of the handle becoming hot when the heating type cigarette device 100 is used. Moreover, the flange 4 and the heater can be firmly fixed by the first portion 41 having a large thickness. As a result, it is possible to suppress the transfer of heat to the main body of the heating-type tobacco device 100 while improving the durability of the heating-type tobacco device 100.
　この場合、第１部分４１は、例えば板状の部材であって、厚みを１～１０ｍｍに、長さを３～１０ｍｍにすることができる。また、第２部分４２は、例えば円筒状の部材であって、厚みを１～１０ｍｍに、長さを３～３０ｍｍにすることができる。また、第３部分４３は、例えば板状の部材であって、厚みを１～１０ｍｍに、長さを３～１０ｍｍにすることができる。第１部分４１、第２部分４２および第３部分４３は、それぞれ別の部材で形成されていてもよい。第１部分４１および第３部分４３は、第２部分４２よりも熱伝導率が低い部材であってもよい。 In this case, the first portion 41 is, for example, a plate-shaped member, and can have a thickness of 1 to 10 mm and a length of 3 to 10 mm. The second portion 42 is, for example, a cylindrical member, and can have a thickness of 1 to 10 mm and a length of 3 to 30 mm. The third portion 43 is, for example, a plate-shaped member, and can have a thickness of 1 to 10 mm and a length of 3 to 10 mm. The first portion 41, the second portion 42, and the third portion 43 may be formed of different members. The first portion 41 and the third portion 43 may be members having a lower thermal conductivity than the second portion 42.
　また、図３に示すように、発熱抵抗体２は、発熱部２１およびリード部２２を有し、基体１は、発熱部２１が設けられた加熱領域１１と、リード部２２が設けられた非加熱領域１２と、を有し、第３部分４３は、加熱領域１１に固定されていてもよい。この場合は、第３部分４３が非加熱領域１２に設けられている場合と比較して、基体１のうち先端側を固定することができる。そのため、基体１のうちフランジ４の外に出た部分の長さを短くすることができる。これにより、例えばヒータにたばこを抜き差しする過程で、基体１の先端に外力が加わった場合に、基体１のうち第３部分４３に固定される部分に加わる力のモーメントを低減することができる。その結果、基体１のうち第３部分４３に固定される部分において、基体１が折れてしまうおそれを低減することができる。 Further, as shown in FIG. 3, the heat generating resistor 2 has a heat generating portion 21 and a lead portion 22, and the base 1 has a heating region 11 in which the heat generating portion 21 is provided and a non-leading portion 22. The heating region 12 and the third portion 43 may be fixed to the heating region 11. In this case, compared with the case where the third portion 43 is provided in the non-heated region 12, the tip side of the base 1 can be fixed. Therefore, it is possible to shorten the length of the portion of the base 1 that extends outside the flange 4. Accordingly, for example, when an external force is applied to the tip of the base body 1 in the process of inserting and removing the cigarette in the heater, the moment of the force applied to the portion of the base body 1 fixed to the third portion 43 can be reduced. As a result, it is possible to reduce the risk that the base body 1 will be broken at the portion of the base body 1 that is fixed to the third portion 43.
　また、発熱抵抗体２は、発熱部２１およびリード部２２を有し、基体１は、発熱部２１が設けられた加熱領域１１と、リード部２２が設けられた非加熱領域１２と、を有し、第３部分４３は、非加熱領域１２に固定されていてもよい。この場合は、第３部分４３が加熱領域１１に設けられている場合と比較して、第３部分４３に伝わる熱量を低減することができる。これにより、加熱式たばこ装置１００本体への熱の伝わりを抑制することができる。その結果、加熱式たばこ装置１００の使用時に、持ち手が熱くなるおそれを低減できる。 The heating resistor 2 has a heating portion 21 and a lead portion 22, and the base 1 has a heating region 11 in which the heating portion 21 is provided and an unheated region 12 in which the lead portion 22 is provided. However, the third portion 43 may be fixed to the non-heated region 12. In this case, the amount of heat transferred to the third portion 43 can be reduced as compared to the case where the third portion 43 is provided in the heating region 11. Thereby, heat transfer to the main body of the heating-type tobacco device 100 can be suppressed. As a result, it is possible to reduce the risk of the handle becoming hot when the heating type cigarette device 100 is used.
　また、図４に示すように、フランジ４は、基体１の一方の端面に接触していてもよい。これにより、フランジ４と基体１の一方の端面との間に、たばこ葉等が付着するおそれを低減できる。その結果、付着物により喫煙時の風味が悪化するおそれを低減することができる。 Further, as shown in FIG. 4, the flange 4 may be in contact with one end surface of the base body 1. As a result, it is possible to reduce the risk that tobacco leaves or the like will adhere between the flange 4 and one end surface of the base 1. As a result, it is possible to reduce the risk of the attached matter deteriorating the flavor during smoking.
　また、図５に示すように、フランジ４は、弾性部材５を介して、基体１の一方の端面に接触していてもよい。フランジ４に外力が加わった際に、弾性部材５が変形することで、基体１に生じる応力を低減することができる。そのため、基体１が破損するおそれを低減することができる。その結果、加熱式たばこ用ヒータ１０の耐久性を高めることができる。弾性部材５は、フランジ４よりも弾性率が低い部材にすることができる。弾性部材５は、例えば樹脂等の部材を用いることができる。 Further, as shown in FIG. 5, the flange 4 may be in contact with one end surface of the base body 1 via the elastic member 5. When an external force is applied to the flange 4, the elastic member 5 is deformed, so that the stress generated in the base 1 can be reduced. Therefore, it is possible to reduce the possibility that the base body 1 is damaged. As a result, the durability of the heating type tobacco heater 10 can be improved. The elastic member 5 can be a member having a lower elastic modulus than the flange 4. As the elastic member 5, a member made of resin or the like can be used.
　また、図６に示すように、フランジ４は一方の表面に凹部を有しており、凹部の内部に基体１の一方の端面が位置していてもよい。これにより、フランジ４と基体１の一方の端面との間に、たばこ葉等が付着するおそれを低減できる。その結果、付着物により喫煙時の風味が悪化するおそれを低減することができる。 Further, as shown in FIG. 6, the flange 4 may have a concave portion on one surface, and one end surface of the base 1 may be located inside the concave portion. As a result, it is possible to reduce the risk that tobacco leaves or the like will adhere between the flange 4 and one end surface of the base 1. As a result, it is possible to reduce the risk of the attached matter deteriorating the flavor during smoking.
　また、図７に示すように、フランジ４は、接合材６によって、接続端子３に固定されていてもよい。接合材６は、例えば、接続端子３よりも弾性率が小さい部材であってもよい。これにより、接続端子３とフランジ４の固定部分に応力が集中し、接続端子３が破損してしまうおそれを低減することができる。その結果、加熱式たばこ用ヒータ１０の耐久性を高めることができる。また、接合材６は、弾性部材５と同じ部材であってもよい。この場合、弾性部材５と接合材６との間の熱膨張差による応力を低減することができる。そのため、弾性部材５と接合材６との間で剥離が生じるおそれを低減できる。その結果、加熱式たばこ用ヒータ１０の耐久性を高めることができる。 Further, as shown in FIG. 7, the flange 4 may be fixed to the connection terminal 3 by the bonding material 6. The bonding material 6 may be, for example, a member having a smaller elastic modulus than the connection terminal 3. As a result, it is possible to reduce the risk that the stress concentrates on the fixed portion between the connection terminal 3 and the flange 4 and the connection terminal 3 is damaged. As a result, the durability of the heating type tobacco heater 10 can be improved. Further, the bonding material 6 may be the same member as the elastic member 5. In this case, the stress due to the difference in thermal expansion between the elastic member 5 and the bonding material 6 can be reduced. Therefore, the risk of peeling between the elastic member 5 and the bonding material 6 can be reduced. As a result, the durability of the heating type tobacco heater 10 can be improved.
　また、図８に示すように、フランジ４は、接続端子３に固定されて、前記長手方向に垂直な方向に伸びる第１部分４１と、第１部分４１に連続し、長手方向に伸びる第２部分４２と、第２部分４２に連続し、長手方向に垂直な方向であって、基体１に向かう方向に伸びる第３部分４３と、を有しており、第３部分４３と基体１との間に隙間があってもよい。これにより、基体１の熱が第３部分４３に伝わるおそれを低減できる。また、たばこ挿入時に基体１に外力が加わったときに基体１が第３部分４３に触れることによって、基体１の変形、破損を抑制することができる。この場合、第３部分４３のうち基体１に面する部位に、弾性部材５が設けられていてもよい。この場合は、また、たばこ挿入時に基体１に外力が加わったときに基体１が第３部分４３に触れた場合に、弾性部材５が応力を低減することができる。その結果、基体１が破損するおそれを低減することができる。 Further, as shown in FIG. 8, the flange 4 is fixed to the connection terminal 3 and has a first portion 41 extending in a direction perpendicular to the longitudinal direction, and a second portion continuous with the first portion 41 and extending in the longitudinal direction. It has a portion 42 and a third portion 43 which is continuous with the second portion 42 and which is perpendicular to the longitudinal direction and extends in the direction toward the base body 1. There may be a gap between them. This can reduce the risk that the heat of the base 1 is transferred to the third portion 43. Further, the deformation and damage of the base 1 can be suppressed by the base 1 coming into contact with the third portion 43 when an external force is applied to the base 1 during the insertion of the cigarette. In this case, the elastic member 5 may be provided in a portion of the third portion 43 facing the base body 1. In this case, the elastic member 5 can reduce the stress when the base 1 comes into contact with the third portion 43 when an external force is applied to the base 1 during the insertion of the cigarette. As a result, it is possible to reduce the risk that the substrate 1 will be damaged.
　また、図９に示すように、加熱式たばこ装置１００は、上記の加熱式たばこ用ヒータ１０と、フランジ４に固定されたハウジング７とを備えていてもよい。これにより、加熱式たばこ装置１００の耐久性を高めることができる。 Further, as shown in FIG. 9, the heating type tobacco device 100 may include the heating type tobacco heater 10 and the housing 7 fixed to the flange 4. Thereby, the durability of the heating type tobacco device 100 can be improved.
