従来のヒータにおいて、フランジ部を設けて基体を保持する際には、基体のうち発熱抵抗体が設けられていない非発熱領域に固定されていた。このようなヒータにおいては、ヒータの小型化が困難であった。   In a conventional heater, when a base is held by providing a flange portion, the base is fixed to a non-heat generating region in the base where a heating resistor is not provided. In such a heater, it is difficult to reduce the size of the heater.

本開示のヒータは、長手方向を有する絶縁基体と、該絶縁基体の内部または表面に設けられて、折返し部を有する発熱抵抗体とを備え、前記絶縁基体の前記発熱抵抗体が設けられた発熱領域に、保持部材が固定されており、該保持部材は、前記発熱領域のうち前記折返し部の直上に固定されていることを特徴とする。   The heater of the present disclosure includes an insulating base having a longitudinal direction and a heating resistor provided inside or on the surface of the insulating base and having a folded portion, and the heat generation provided with the heating resistor of the insulating base. A holding member is fixed to the region, and the holding member is fixed immediately above the folded portion in the heat generating region.

本開示のヒータによれば、保持部材は、発熱領域のうち折返し部の直上に固定されている。これにより、絶縁基体の長手方向の長さを低減することができる。その結果、ヒータを小型化することができる。   According to the heater of the present disclosure, the holding member is fixed immediately above the folded portion in the heat generation region. Thereby, the length of the insulating substrate in the longitudinal direction can be reduced. As a result, the heater can be reduced in size.

The insulating substrate 1 may be a plate-like member as shown in FIG. 1 or a cylindrical member as shown in FIG. Further, the insulating substrate 1 may be a rod-shaped member.

絶縁基体１の寸法は、例えば絶縁基体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、絶縁基体１は、端部に被加熱物を挿入しやすいように、先端が尖っていてもよい。また、絶縁基体１は、先端または全体が反ってもよい。 The dimensions of the insulating base 1 are, for example, when the insulating base 1 is plate-shaped, and when the shape of the main surface is rectangular, the length of the long side is 5 to 20 mm and the length of the short side is 1 to 10 mm The thickness can be 0.08 to 1 mm. The insulating base 1 may have a sharp tip so that an object to be heated can be easily inserted into the end. Further, the insulating base 1 may be warped at the tip or the whole.

また、絶縁基体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。   When the insulating substrate 1 is cylindrical, 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、例えば絶縁基体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、被加熱物を加熱することができる。発熱抵抗体２は、絶縁基体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 insulating substrate 1. The heating resistor 2 is, for example, a linear or belt-shaped member.

Further, the heating resistor 2 may have alumina or silicon nitride as a component other than metal. The dimensions of the heating resistor 2 are, for example, a length of 5 to 50 mm, a width of 0.2 to 2 mm, and a thickness of 0.005 to 0.1 mm.

発熱抵抗体２は、絶縁基体１の先端から後端まで設けられていてもよい。また、図１に示すうに、発熱抵抗体２は、リード部６に接続されていてもよい。このときに、リード部６は、発熱抵抗体２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６における発熱を低減することができる。また、発熱抵抗体２は、図２に示すように、絶縁基体１の後端側において、電極パッド５に接続されており、電極パッド５を介して、端子４に接続されていてもよい。   The heating resistor 2 may be provided from the front end to the rear end of the insulating substrate 1. As shown in FIG. 1, the heating resistor 2 may be connected to the lead portion 6. At this time, the lead portion 6 can have a resistance value smaller than that of the heating resistor 2. Thereby, the heat_generation | fever in the lead part 6 can be reduced. Further, as shown in FIG. 2, the heating resistor 2 is connected to the electrode pad 5 on the rear end side of the insulating base 1, and may be connected to the terminal 4 through the electrode pad 5.

絶縁基体１は、発熱抵抗体２が設けられた発熱領域１１を有している。ここで、発熱領域１１とは、ヒータ１０が実質的に発熱する領域を意味しており、具体的には、例えば絶縁基体１の先端から発熱抵抗体２とリード部６との境界までの領域である。また、例えば、発熱抵抗体２は、絶縁基体１の先端から後端まで設けられていている場合は、絶縁基体１の先端から後端までの領域が発熱領域１１である。   The insulating substrate 1 has a heat generating region 11 provided with a heat generating resistor 2. Here, the heat generating region 11 means a region where the heater 10 substantially generates heat. Specifically, for example, a region from the tip of the insulating base 1 to the boundary between the heating resistor 2 and the lead portion 6. It is. Further, for example, when the heating resistor 2 is provided from the front end to the rear end of the insulating substrate 1, the region from the front end to the rear end of the insulating substrate 1 is the heat generation region 11.

また、図２に示すように絶縁基体１は、発熱領域１１以外の領域であって、電極パッド５またはリード部６を有する、非発熱領域１２を有していてもよい。この場合は、非発熱領域１２は、ヒータ１０が実質的に発熱していない領域を意味している。具体的には、例えば発熱抵抗体２とリード部６との境界から絶縁基体１の後端までの領域である。   In addition, as shown in FIG. 2, the insulating base 1 may have a non-heat generating region 12 that is an area other than the heat generating region 11 and has the electrode pad 5 or the lead portion 6. In this case, the non-heat generating region 12 means a region where the heater 10 does not substantially generate heat. Specifically, for example, a region from the boundary between the heating resistor 2 and the lead portion 6 to the rear end of the insulating substrate 1.

保持部材３は、絶縁基体１を保持するための部材である。保持部材３は、発熱領域１１において固定されている。これにより、絶縁基体１の長手方向の長さを低減することができる。その結果、ヒータ１０を小型化することができる。例えば図１〜図４に示す例においては、保持部材３は、Ａに示す部位に固定されている。   The holding member 3 is a member for holding the insulating substrate 1. The holding member 3 is fixed in the heat generating region 11. Thereby, the length of the insulating substrate 1 in the longitudinal direction can be reduced. As a result, the heater 10 can be reduced in size. For example, in the example shown in FIGS. 1 to 4, the holding member 3 is fixed to a portion indicated by A.

保持部材３は、例えば絶縁基体１の長手方向を囲むように設けられていてもよい。保持部材３は、例えばセラミック材料等からなる。保持部材３は、例えば接着剤等によって絶縁基体１に固定されていてもよい。   The holding member 3 may be provided so as to surround the longitudinal direction of the insulating base 1, for example. The holding member 3 is made of, for example, a ceramic material. The holding member 3 may be fixed to the insulating base 1 with, for example, an adhesive.

また、図４に示すように、ヒータ１０は、筒状であってもよい。これにより、筒の内側に被加熱物を挿入することによって、被加熱物を加熱することができる。なお、図４は斜視図であるが、理解しやすさを優先して、保持部材３を省略して示している。また、図４は斜視図であるが、理解しやすさを優先して、発熱抵抗体２を透過して示している。   Moreover, as shown in FIG. 4, the heater 10 may be cylindrical. Accordingly, the object to be heated can be heated by inserting the object to be heated inside the cylinder. Although FIG. 4 is a perspective view, the holding member 3 is omitted for the sake of easy understanding. FIG. 4 is a perspective view, but shows the heat generating resistor 2 in a transparent manner, giving priority to easy understanding.

また、本開示の加熱式タバコ用装置は、ヒータ１０を加熱手段として備えている。これにより、加熱式タバコ用装置を小型化することができる。   Moreover, the apparatus for heating cigarettes of this indication is equipped with the heater 10 as a heating means. Thereby, the apparatus for heating cigarettes can be reduced in size.
