Description

Electric heating type cigarette lighter and smoking system for carbon heat source type scent suction tool

The invention relates to an electric heating lighter and a smoking system for a carbon heat source type flavoring and smoking appliance.

There are known carbon heat source type flavoring tasters, which are provided with: a cylindrical holder, which contains a fragrance generating source; and a carbon heat source, which is provided at an end in the axial direction of the holder (refer to, for example, the following Patent Document 1). This kind of carbon heat source type scent absorbing tool is to heat the scent generation source without burning the scent generation source by the heat generated by burning the carbon heat source, to absorb the mist containing the scent component generated from the scent generation source (aerosol).

Compared with the paper cigarette of the conventional technology, the above-mentioned carbon heat source type flavoring taster has the problems of difficulty in igniting the carbon heat source and time-consuming ignition of the carbon heat source. In addition, when the carbon heat source is damp, it is obviously very difficult to ignite. Therefore, in order to prevent the carbon heat source from absorbing moisture before smoking, it is also necessary to wrap the carbon heat source type flavoring applicator to prevent the moisture film from being individually wrapped and packaging.

As far as the cigarette lighter for the carbon heat source type flavoring and smoking appliance is concerned, the electric heating type cigarette lighter has the advantage of resisting wind. However, when the conventional electric cigarette lighter is used to ignite the carbon heat source of the carbon heat source type flavoring applicator, it is necessary to supply a sufficient amount of power to ignite the carbon heat source to the electric heating line.

The present invention has been completed in light of the above circumstances, and aims to provide a technology for an electric-type cigarette lighter suitable for igniting a carbon heat source of a carbon heat source type flavoring applicator.

The present invention that solves the above-mentioned problems is an electric-type cigarette lighter for a carbon heat source type flavoring applicator provided with a cylindrical holder containing a flavor generating source, and a carbon heat source provided at an axial end of the holder The electric cigarette lighter includes an electric heater for igniting the carbon heat source; the electric heater includes a bottom surface heating portion for heating the front end surface of the carbon heat source, and the carbon heat source Side heating part for the side.

Based on the above-mentioned carbon heat source type scent absorbing electric appliance The cigarette lighter can simultaneously heat the front end surface and the side surface of the carbon heat source with the bottom surface heating portion and the side surface heating portion. Therefore, even with small power, the front end portion and the side peripheral portion of the carbon heat source can be ignited in a short time. Therefore, even if the carbon heat source contains moisture, the carbon heat source can be ignited. Therefore, it is not necessary to individually wrap the carbon heat source type flavoring applicator as in the conventional technology.

In addition, in the electric-type cigarette lighter of the present invention, the bottom heating portion and the side heating portion may be formed integrally, or may be formed independently (for example, separated from each other). In addition, the bottom surface heating portion and the side surface heating portion may be formed using, for example, an electric heating coil (coil), or may be formed using a plate-shaped resistance heating element.

Here, the electric heater system may have a bottomed cylindrical shape as a whole, and may be formed by a series of electrothermal coil wires connected to the bottom surface heating portion and the side surface heating portion. The wire system such as the electric heating coil wire can be easily bent into an arbitrary shape, so it is suitable as a material constituting the electric heater. As for the electric heating coil wire, a Kanthal wire can be suitably used to withstand a large electric power supply. However, the material forming the electric heater is not limited to the electric heating coil wire. For example, it is possible to bend a resistive heating element formed into a planar meandering shape, a spiral shape, or a spiral plate shape, thereby producing an electric heater having a bottomed cylindrical shape as a whole.

In addition, the bottom heating portion may have a disk shape and the side heating portion may have a cylindrical shape. At least a part of the height of the side heating portion may have a diameter greater than that of the bottom heating portion Big. By doing as described above, it is possible to suppress excessive resistance when the carbon heat source is inserted inside the side heating portion of the electric heater Degrees increase. As a result, when the carbon heat source of the carbon heat source type flavor applicator is inserted into and removed from an electric heater, the carbon heat source can be prevented from being broken, broken, or peeled.

For example, the side heating portion may be configured to have a tapered diameter as the diameter increases away from the bottom heating portion. According to this, not only can the electric heater properly heat the carbon heat source, but also the resistance when the carbon heat source is inserted inside the side heating portion of the electric heater can be reduced appropriately. Therefore, damage to the carbon heat source during ignition can be appropriately suppressed.

Here, the electric cigarette lighter system of the present invention may further include a holding portion that holds the holder. By holding the holder of the carbon heat source-type flavor odor applicator with the holder, the carbon heat source can be ignited in a stable posture. The holder holds the holder, for example, the carbon heat source can be inserted into the heating section at an appropriate angle. That is, the holding portion can also serve as a guide member for inserting the carbon heat source into the heating portion at an appropriate angle. The holding portion may have an inner diameter larger than the outer diameter of the holder, and the ring may be inserted and removed freely. According to the ring-shaped body as described above, the function of holding the holder in a stable posture and the guiding function of inserting the carbon heat source into the electric heater at an appropriate angle can be realized with a simple structure. In addition, the carbon heat source inserted into the electric heater is positioned by abutting the front end surface of the carbon heat source to the bottom surface heating portion. Therefore, it is possible to provide an electrothermal cigarette lighter with excellent usability.

In addition, the electric heating type cigarette lighter system may further include a support body that supports the bottom surface heating portion. At this time, in order to reduce the heat loss from the bottom surface heating portion to the support body due to heat transfer from the bottom surface heating portion, the Preferably, the support body is formed of a material with a low thermal conductivity. From the viewpoint as described above, the thermal conductivity of the support can be 10 W/(m‧K) or less. In addition, the support system is preferably designed to have a thermal conductivity of 5 W/(m‧K) or less, and particularly preferably a thermal conductivity of 1W/(m‧K) or less.

In addition, the support system is deeply trapped in the high temperature due to the heat transferred from the bottom surface heating portion, so it is preferable to form the support body with a material having excellent heat resistance. From the viewpoint of ensuring the heat resistance of the support, the support system preferably has a heat resistance temperature of 150°C or higher, and particularly preferably has a heat resistance temperature of 200°C or higher. Examples of materials with low thermal conductivity and excellent heat resistance as described above include ceramics (ceramic plates).

Here, the support system may include a base and a support provided on the surface of the base and supporting the bottom heating unit.

Here, the support portion may include a plurality of support wall portions provided upright from the base portion and supporting the bottom surface heating portion with the top surface thereof. By supporting the bottom surface heating portion from the top surface of the plate-shaped support wall portion that is provided upright from the base, the function of supporting the bottom surface heating portion can be achieved, and the contact area with the bottom surface heating portion can be reduced, so the carbon heat source can be easily reduced The heat of the bottom heating part is lost due to the heat transfer from the bottom heating part to the supporting part during the ignition.

In addition, the support portion may have a plurality of support wall portions, and an air flow path for supplying air to the carbon heat source when the carbon heat source is ignited is formed between the support wall portions. By forming an air flow path between the plurality of plate-shaped support walls as described above, the When the source is ignited, the air required for the combustion of the carbon heat source can be sufficiently supplied to the carbon heat source, and the carbon heat source can be ignited in a shorter time.

In addition, at least one of the bottom heating portion and the side heating portion may be formed with an air flow path for supplying air to the front end surface of the carbon heat source when the carbon heat source is ignited. By forming the air flow path as at least one of the bottom heating portion and the side heating portion, the air required for the combustion of the carbon heat source can be sufficiently supplied to the carbon heat source, and the carbon heat source can be ignited in a shorter time.

In addition, at least any one of the portion that forms the bottom heating portion and the portion that forms the side heating portion among the electric heating coil wires may be formed between adjacent windings of the electric heating coil wire The gap forms an air flow path for supplying air to the side surface of the carbon heat source when the carbon heat source is ignited by the gap between the coils. By the above method, the air required for the combustion of the carbon heat source can be sufficiently supplied to the carbon heat source with a simple configuration.

In addition, the present invention may also be a smoking system, including: a carbon heat source type flavoring applicator, a cylindrical holder including a flavor generating source, and a carbon heat source provided at an axial end of the holder ; And any of the aforementioned electric cigarette lighters. According to the smoking system as described above, the aforementioned advantages can be enjoyed.

In the smoking system, the carbon heat source may include: a body portion provided with a hollow portion in ventilating communication along the long axis direction of the carbon heat source; and a groove provided at the ignition end of the body portion and The hollow portion communicates; the groove extends by extending in a direction across the body portion It is extended and exposed on the side of the aforementioned ignition end. By forming a groove at the ignition end of the carbon heat source as described above, the heat from the bottom heating portion is efficiently transferred to the ignition end, specifically, from the start of combustion to the initial puff In the period until now, good ignitability is obtained.

In addition, in the case of igniting a carbon heat source type flavoring applicator having a groove formed at the ignition end of the carbon heat source as described above, it is preferably between the support wall portions of the support portion of the electric cigarette lighter The configuration for forming the air flow path may be combined with the configuration for forming the air flow path in at least one of the bottom heating portion and the side heating portion. The air supplied to the internal space of the heating portion via the air flow path passes through the hollow portion formed in the main body of the carbon heat source after being heated by the electric heater. This promotes the generation of flavor from the flavor generating source contained in the holder of the carbon heat source type flavoring applicator, and sufficient flavor can be supplied to the smoker from the initial puff.

In addition, the height dimension of the side heating portion may be larger than the depth dimension of the groove from the front end of the carbon heat source to the groove bottom where the groove is exposed on the side surface. By igniting the carbon heat source as described above, the groove at the ignition end of the carbon heat source can be covered with the side heating portion of the electric cigarette lighter. According to the electric cigarette lighter of the present invention, the ignition end portion of the carbon heat source is ignited together with the side peripheral portion. Therefore, when smoking with a carbon heat source type flavor applicator, the The air flowing into the hollow portion of the body portion through the groove can be heated by the side peripheral portion of the ignited carbon heat source. In addition, when smoking with a carbon heat source type flavoring applicator, the air flowing into the hollow portion of the body portion through the groove formed at the ignition end of the carbon heat source can also be performed by the side heating portion heating. As a result, it is possible to further promote the generation of flavor from the flavor generating source contained in the holder.

In addition, the height dimension of the side heating portion may be designed to be smaller than the length of the carbon heat source protruding from the holder in the long axis direction. According to this, it is possible to suppress the end portion of the holder from contacting the side heating portion when the carbon heat source is ignited or smoked. As a result, it is possible to suppress the end portion of the holder from being directly heated by the side heating portion, and it is possible to suppress the holder from catching fire, scorching, damage, or the like.

In addition, the effective width dimension of the bottom heating portion may be larger than the diameter of the carbon heat source. By doing as described above, when the carbon heat source is ignited, the front end surface of the carbon heat source can be brought into contact with the bottom surface heating portion of the electric heater. Thereby, the heating efficiency of the front end surface of the carbon heat source by the bottom surface heating unit can be further improved.

In addition, the electric heater system may be configured such that when the carbon heat source is ignited, at least a part of the front end surface of the carbon heat source is in contact with the bottom surface heating portion. Thereby, the heating efficiency of heating the front end surface of the carbon heat source by the bottom heating unit can be further improved. In addition, the resistance when the carbon heat source can be inserted inside the side heating portion of the electric heater can be reduced appropriately. Therefore, damage to the carbon heat source during ignition can be appropriately suppressed.

In addition, the electric heater system may be configured such that when the carbon heat source is ignited, at least a part of the front end surface of the carbon heat source abuts on the bottom surface heating portion, and the side surface of the carbon heat source and the side surface The heating section does not abut. Accordingly, it is appropriate to raise the bottom surface The heating efficiency of the heating portion heating the front end surface of the carbon heat source can also appropriately suppress damages such as breakage, chipping, and peeling of the carbon heat source during ignition.

In addition, the height dimension of the side heating portion may be set so that the side heating portion covers at least a part of the flavor generating source when the carbon heat source is ignited. According to this, it is possible to further promote the generation of flavor from the flavor generating source contained in the holder.

The shortest distance between the side surface of the carbon heat source and the electric heater may be smaller than the shortest distance between the electric heater and the side surface of the holder. Here, both the bottom heating portion and the side heating portion of the electric heater can be used as the starting point of the shortest distance dimension. The shortest distance between the outer surface of the carbon heat source and the heating part may be the shortest distance between the outer surface of the carbon heat source and the bottom heating part, or the shortest distance between the outer surface of the carbon heat source and the side heating part. With the above configuration, it is possible to supply sufficient heat to the ignition end of the carbon heat source, and to suppress excessive heat supply to the holder. In addition, the shortest distance between the side surface of the carbon heat source and the electric heater may be smaller than the shortest distance between the electric heater and the side surface of the holder.

In addition, means for solving the problems of the present invention can be adopted in combination as much as possible.

According to the present invention, it is possible to provide a technology related to an electric heating cigarette lighter suitable for igniting a carbon heat source of a carbon heat source type flavoring applicator.

At this time, the holder 8 is guided by the guide surface 31 of the holder 3, so that the ignition front end surface 62A of the carbon heat source 6 provided at the end of the holder 8 and the bottom heating unit 41 can face each other. The carbon heat source 6 is smoothly led to the electric heater 4. In addition, in the present embodiment, the central axis CL of the electric heater 4 and the central axis of the annular body forming the holding portion 3 are designed to be coaxial, so that the carbon heat source 6 can be guided to the electric The ignition hollow 4B of the heater 4 is inside.

FIG. 10 shows that after the carbon heat source 6 and the holder 8 of the carbon heat source type flavor applicator 5 are partially inserted into the housing 2 from the insertion port 30, the carbon heat source 6 is housed in the hollow of the electric heater 4 for ignition In the state of the part 4B, the holder 8 is positioned and held by the holding part 3. In FIG. 10, the outline of the carbon heat-source type flavoring applicator 5 in which the holder 8 is positioned and held by the holder 3 is schematically shown by chain lines.

FIG. 11 is a diagram illustrating a state where the carbon heat source 6 is housed in the hollow portion 4B for ignition of the electric heater 4.

That is, by energizing the bottom heating unit 41 and the side heating unit 42 formed by the series-connected electric heating coil wires, the electric heating coil wires forming the bottom heating unit 41 and the side heating unit 42 are brought into a red hot state. The electric heater 4 according to the present embodiment includes a bottom surface heating portion 41 for heating the ignition front end surface 62A of the carbon heat source 6 housed in the ignition hollow portion 4B, and a side surface (side peripheral surface) 63A for heating the carbon heat source 6 Since the side heating portion 42 is used, the ignition front end surface 62A and the side surface 63A of the carbon heat source 6 can be heated at the same time. As a result, the ignition end portion 62 and the side peripheral portion 63 of the carbon heat source 6 can be efficiently heated, so the ignition end portion 62 and the side peripheral portion 63 can be easily ignited in a short time. In addition, according to the electric-type cigarette lighter 1 of the present embodiment, the carbon heat source 6 has excellent ignitability, so it is easy to ignite the carbon heat source 6 even if the carbon heat source 6 contains moisture. Therefore, it is not necessary to individually wrap the carbon heat source type flavoring applicator as in the conventional technology. In addition, according to the electric cigarette lighter 1 of the present embodiment, even if the electric power supplied from the power source 14 to the electric heater 4 is small, the carbon heat source 6 can be easily ignited in a short time, so the capacity of the power source can be reduced Electric design.

In addition, according to the electric heater 4 of the present embodiment, the bottom surface heating portion 41 and the side surface heating portion 42 are formed by series-connected electric heating coil wires. Therefore, compared with the bottom surface heating portion 41 and the side surface heating portion 42 individually, the number of terminals can be reduced. The number. However, the bottom heating unit 41 and the side heating unit 42 may be formed by individual electrothermal coil wires.

In addition, the electric heater 4 series bottom surface heating portion 41 has The shape of the disc and the side heating portion 42 have a cylindrical shape, so the bottom heating portion 41 is brought into contact with the ignition front end surface 62A of the carbon heat source 6 housed in the ignition hollow portion 4B and the side heating portion 42 is opposed to the carbon heat source 6 The side surface 63A can efficiently heat the carbon heat source 6.

In addition, when using the electric-type cigarette lighter 1 of the present embodiment, the smoker system is preferably to ignite the carbon heat source 6 while sucking (sucking) the filter 9 of the carbon heat source type flavoring taster 5 . According to the electric heater 4 of the present embodiment, as shown in FIG. 11, a side air flow path C1 is formed between the windings 421 to 427 of the side heating section 42, and each winding 411 of the bottom heating section 41 The bottom air flow path C2 is formed between 414. Accordingly, a sufficient amount of oxygen can be supplied to the ignition end 62 of the carbon heat source 6 when the carbon heat source 6 is ignited, so that the ignition end 62 of the carbon heat source 6 can be ignited in a shorter time. In addition, the electric cigarette lighter 1 is formed with a vent hole 20 at an appropriate place in the housing 2, and sufficient fresh air is supplied from the vent hole 20 to the inside of the housing 2, so that when the carbon heat source 6 is ignited There is a sufficient amount of oxygen around the electric heater 4.

According to this, when the electric heater 4 is energized, it is possible to suppress the end portion of the holder 8 from contacting the side heating portion 42. As a result, it is possible to suppress the end portion of the holder 8 from being directly heated by the side heating section 42, and thus it is possible to suppress the holder from catching fire, burning, or damage.

In addition, in the present embodiment, the effective width dimension of the bottom heating portion 41 of the electric heater 4 is designed to be larger than the diameter Dc1 of the carbon heat source 6. The effective width dimension of the bottom surface heating portion 41 here refers to an effective width that can abut on the ignition front end surface 62A of the carbon heat source 6, and in the present embodiment corresponds to the inner diameter Ri1 of the side heating portion 42. As described above, by setting the effective width dimension of the bottom heating portion 41 (the inner diameter Ri1 of the side heating portion 42) to be larger than the diameter Dc1 of the carbon heat source 6, the ignition front end surface 62A of the carbon heat source 6 can be brought into contact with the bottom surface The heating unit 41 can increase the heating efficiency of the ignition front end surface 62A of the carbon heat source 6 when the electric heater 4 is energized.

In addition, the electric heater 4 is not necessary to make the bottom surface heating portion 41 contact the entire ignition front end surface 62A of the carbon heat source 6 when the carbon heat source 6 is ignited, and the bottom surface heating portion 41 and the ignition front end surface may also be used At least a part of 62A abuts. By configuring the electric heater 4 such that the bottom surface heating portion 41 contacts at least a part of the ignition front end surface 62A of the carbon heat source 6, the carbon heat source 6 can be ignited in a shorter time. In addition, as described above, the electric heater 4 is designed such that the inner diameter Ri1 of the side heating portion 42 is larger than the diameter Dc1 of the carbon heat source 6, so that the side surface 63A of the carbon heat source 6 and the side heating portion 42 are not in contact . According to this, when the carbon heat source 6 is accommodated in the hollow portion 4B for ignition, it is possible to suppress breakage, breakage, chipping, and the like of the carbon heat source 6.

In addition, the support plate 12 provided with the electric heater 4 of this embodiment is configured to support the bottom surface heating portion 41 by the top surface 121A of the support wall portion 121 provided upright from the base 120, so that the support plate 12 and the bottom surface heating can be reduced The contact area of the portion 41. Thereby, when the carbon heat source 6 is ignited, the heat generation loss of the electric heater 4 can be reduced. In addition, the support plate 12 is formed of pottery (ceramic plate) having a low thermal conductivity, so that the heat of the electric heater 4 when the carbon heat source 6 is ignited can be appropriately reduced by the support plate 12.

Here, both the bottom heating portion 41 and the side heating portion 42 of the electric heater 4 can be used as the starting point of the above-mentioned shortest distance dimension. The shortest distance between the outer surface of the carbon heat source 6 and the electric heater 4 may be the shortest distance between the outer surface of the carbon heat source 6 and the bottom heating unit 41, or the shortest distance between the outer surface of the carbon heat source 6 and the side heating unit 42 Distance size. With the above configuration, it is possible to suppress the supply of excessive heat to the holder 8 while supplying sufficient heat to the ignition end 62 of the carbon heat source 6. In this embodiment, the shortest distance between the side surface 63A of the carbon heat source 6 and the side heating portion 42 is designed to be smaller than the shortest distance between the side heating portion 42 and the side surface of the holder 8. Thereby, the ignition end 62 of the carbon heat source 6 is heated efficiently, It is also possible to suppress excessive heat supply to the holder 8.

In addition, with regard to the carbon heat source 6 of the carbon heat source type flavor odor applicator 5 of the present embodiment, the groove 62B formed in the ignition front end surface 62A of the ignition end 62 is exposed by extending in a direction crossing the body 61 The side surface (side peripheral surface) 63A of the ignition end 62. In addition, the height dimension Lh1 of the side heating portion 42 of the electric heater 4 is designed to be larger than the trench depth dimension Lc2 from the ignition front end surface 62A of the carbon heat source 6 to the portion where the trench 62B is exposed on the side surface 63A, that is, the trench bottom. According to this, when the smoker ignites the carbon heat source 6 while absorbing the carbon heat source type flavoring taster 5, the ignition end 62 of the carbon heat source 6 is ignited together with the side peripheral portion 63. When the heat-source type flavoring applicator 5 smokes, the air flowing into the hollow portion 61A of the body portion 61 through the groove 62B formed in the ignition end 62 of the carbon heat source 6 can be ignited on the side circumference of the ignited carbon heat source 6 Section 63 is heated. In addition, when smoking with the carbon heat source type flavoring applicator 5, the air heated by the side heating portion 42 of the electric heater 4 is introduced from the groove 62B of the ignition end 62 through the hollow portion 61A to the hollow portion of the body portion 61 Within 61A. That is, according to the carbon heat source type flavoring applicator 5, the air flowing into the hollow portion 61A through the groove 62B of the ignition end 62 during smoking can also be heated by the side peripheral portion 63 of the ignited carbon heat source 6 . As a result, the generation of flavor from the flavor generating source 7 contained in the holder 8 is promoted, and a sufficient amount of flavor can be supplied to the smoker immediately after the smoker starts to taste (at the time of initial smoking).

In addition, according to the electric cigarette lighter 1 of the present embodiment, the case 2 is provided, and the electric heater 4 is housed in the case 2, so it is possible to The carbon heat source 6 of the carbon heat source type fragrance absorbing tool 5 is ignited under the weather. However, the electric heater 4 of the electric cigarette lighter 1 can also be exposed to the external space.

In addition, the electric heater 4 of the present embodiment can adopt various modifications. For example, in the above-mentioned embodiment, although the example in which the bottom heating portion 41 and the side heating portion 42 are formed by the electric heating coil wires connected in series in the electric heater 4 is described, it is not limited to this. For example, the electric heater 4 may be manufactured by bending a member formed by winding a resistive heating element in a planar shape into a bottomed cylindrical shape. In this case, it is needless to say that the bottom heating unit 41 and the side heating unit 42 may be individually manufactured by using members formed by meandering the resistance heating element in a planar shape.

<Modification 1>

The electric heater 400 of this modification is designed so that the diameter of the side heating portion 42 is larger than the diameter of the bottom heating portion 41 in at least a part of the height direction of the side heating portion 42. In the example shown in FIG. 12, in the electric heater 400, the diameter of the side heating portion 42 increases in a tapered shape as the distance from the bottom heating portion 41 increases.

In addition, the electric heater 400 is designed such that the height dimension Lh1 of the side heating portion 42 is larger than the carbon heat source protrusion length Lc1 of the carbon heat source type flavor applicator 5, so that the side heating portion 42 covers the fragrance of the holder 8 The height dimension Lh1 of the side heating portion 42 is set so that at least a part of the source 7 is generated. As shown in FIG. 12, in a state where the carbon heat source 6 is housed in the ignition hollow portion 4B of the electric heater 400, the side heating portion 42 is coated laterally of the fragrance generating source 7, thereby 6 When the ignition is performed, not only the carbon heat source 6 but also the flavor generation source 7 can be heated at the same time. Thereby, when the carbon heat source 6 is ignited, the generation of the fragrance from the fragrance generation source 7 can be promoted. Therefore, it is possible to supply a sufficient amount of flavor to the smoker immediately after the smoker starts smoking.

In addition, as shown in FIG. 12, in a state where the ignition front end surface 62A of the carbon heat source 6 abuts on the bottom surface heating portion 41 of the electric heater 400, the holder 8 is not separated from the side heating portion 42 of the electric heater 400 The inner diameter Ri1 of the side heating portion 42 is adjusted so that interference occurs. In addition, in the electric heater 400 of the present modification, the diameter of the side heating portion 42 increases in a tapered shape as the distance from the bottom heating portion 41 increases, so that the side surface is heated at least in part in the height direction of the side heating portion 42 The diameter of the portion 42 is designed to be larger than the diameter of the bottom heating portion 41. Therefore, it is easy to insert the carbon heat source 6 into the ignition hollow 4B. In addition, it is possible to suppress the occurrence of damage such as breakage, breakage, or chipping of the carbon heat source 6 when the carbon heat source 6 is inserted into and removed from the ignition hollow portion 4B. In addition, when the electric heater 400 is energized, the side heating portion 42 can face the side surface 63A of the carbon heat source 6, so the carbon heat source 6 can be efficiently ignited in a short time.

<Modification 2>

FIG. 13 is a diagram showing an electric heater 400A of Modification 2. FIG.
