By providing the ventilation hole 103 in the cooling segment 121, when the cigarette stick 100 is sucked, low-temperature air flows into the cooling segment 121 from the outside, volatilization flowing in from the cigarette rod portion 110. It can lower the temperature of ingredients or air. Additionally, the vapor containing the aerosol-generating substrate and the tobacco flavor component is condensed by being cooled by low-temperature air introduced into the cooling segment 121 through the ventilation hole 103. As a result, the production of aerosol is promoted and the size of aerosol particles can be controlled.

When filling the cooling segment 121 with a sheet for cooling volatile components or air flowing into the cooling segment 121 from the cigarette rod 110, the total surface area of the cooling segment 121 is not particularly limited. , for example, 300mm ² /mm or more and 1000mm ² /mm or less. This surface area is the surface area per length (mm) of the cooling segment 121 in the ventilation direction. The total surface area of the cooling segment 121 is preferably 400 mm ² /mm or more, more preferably 450 mm ² /mm or more, while it is preferably 600 mm ² /mm or less, and more preferably 550 mm ² /mm or less.

The cooling segment 121 preferably has a large overall surface area in its internal structure. Accordingly, in a preferred embodiment, the cooling segments 121 may be formed by sheets of thin material that are crimped, then gathered, and folded into small pieces to form channels. The more small folds or creases an element has within a given volume, the larger the total surface area of the cooling segments 121 is. The thickness of the constituent material of the cooling segment 121 is not particularly limited, and may be, for example, 5 μm or more and 500 μm or less, or 10 μm or more and 250 μm or less.

The ventilation hole 103 in the cooling segment 121 is preferably disposed at a distance of 4 mm or more from the boundary between the cooling segment 121 and the filter segment 122. As a result, not only can the cooling ability of the cooling segment 121 be improved, but also the retention of components generated by heating in the cooling segment 121 can be suppressed, thereby improving the delivery amount of the components. In addition, it is preferable that the chip paper 130 has an opening provided at a position immediately above the ventilation hole 103 provided in the cooling segment 121 (a position overlapping vertically). The apertures of the cooling segment 121 are the ratio of air inflow from the aperture when suction is taken at 17.5 ml/sec with an automatic smoker (air inflow from the aperture when the ratio of air suctioned from the inlet end is 100% by volume) It is desirable to install it so that the volume ratio) is 10 to 90 volume%, preferably 50 to 80 volume%, more preferably 55 to 75 volume%, for example, per opening group. This can be achieved by selecting the number of pores (V) from the range of 5 to 50, selecting the diameter of the pores (V) from the range of 0.1 to 0.5 mm, and combining these selections. The air inflow rate can be measured by a method based on ISO9512 using an automatic smoker (for example, a 1-piece automatic smoker manufactured by Borgwaldt).

In the example shown in FIG. 2, the filter segment 122 is comprised of a single segment, but the filter segment 122 may be comprised of a plurality of segments. When the filter segment 122 is composed of a plurality of segments, for example, a hollow segment such as a center hole is placed on the upstream side (tobacco rod portion 110 side), and a hollow segment such as a center hole is placed on the downstream side (inlet end 101 side). As a segment of, an acetate filter whose mouth section is filled with cellulose acetate tow is disposed. According to this aspect, unnecessary loss of generated aerosol can be prevented and the appearance of the cigarette stick 100 can be improved. In addition, from the viewpoint of change in sensation of inhalation and feeling when biting, an acetate filter is placed on the upstream side (tobacco rod portion 110 side), and a center hole, etc. is placed on the downstream side (inlet end 101 side).

The ventilation resistance of the filter segment 122 is a predetermined value from one end surface (first end surface) to the other end surface (second end surface) in a state in which air is not transmitted through the side surface of the filter segment 122. This refers to the air pressure difference between the first cross section and the second cross section when air with an air flow rate (17.5 cc/min) is flowed. The unit of ventilation resistance can generally be expressed as mmH ₂ O. It is known that the relationship between the ventilation resistance of the filter segment 122 and the length of the filter segment 122 is proportional in the commonly used length range (length 5 mm to 200 mm), and when the length of the filter segment 122 is doubled, , the ventilation resistance is also doubled.

The upper surface of each pedestal portion 73 is at the tip of the cigarette rod portion 110 ( It is formed as a positioning bottom surface 731 that is positioned by contacting 102). The positioning bottom surface 731 of each pedestal portion 73 is flat and positioned at the same height within the heating chamber 60. The cigarette stick 100 inserted into the heating chamber 60 is inserted to a specified position from the point when the tip 102 of the cigarette rod portion 110 comes into contact with the positioning bottom surface 731 of each pedestal portion 73. It has specifications that meet the requirements. That is, in the hollow tube heater 21, the position (specified position) of the positioning bottom surface 731 of each pedestal portion 73 corresponds to the innermost position of the heating chamber 60. In a state where the cigarette stick 100 is inserted to the innermost position of the heating chamber 60, the tip 102 of the cigarette rod portion 110 is at the upper part of the gap SP1 formed between the set of pedestals 73. It is witty enough to exceed. When sucking the cigarette stick 10 using the electric heating device 1, the air flowing into the heating chamber 60 of the hollow tube heater 21 from the insertion port 5A is After being introduced to the bottom side of the heating chamber 60 through the gap between the inner wall surface and the cigarette stick 10, it is introduced from the tip 102 of the cigarette rod portion 110 through the gap SP1 to the cigarette rod portion 110. introduced internally.

As shown in FIG. 6, the chamber tube 6 in this embodiment has a heater region RH formed in at least a part of the compression cylinder portion 63. The heater region RH of the compression cylinder portion 63 is a heat generating region for heating at least the tobacco rod portion 110 among the tobacco sticks 100 inserted into the heating chamber 60 from the outer peripheral side, and generates heat by applying electricity. A heater element 23 is installed. In addition, in drawings other than FIG. 6, illustration of the heater element 23 is appropriately omitted. The heater element 23 installed in the heater area RH is an element that generates heat when operating power is supplied from the power source 40, and is not particularly limited. The heater region RH of the compression cylinder portion 63 is, for example, a metal tube such as stainless steel, and a metal thin film heater may be disposed along the outer peripheral surface of the metal tube. A metal thin film heater is a planar heater that uses a metal thin film as a heating element and has flexibility. Additionally, in the heater region RH of the compression cylinder portion 63, a film heater may be disposed along the outer peripheral surface of the metal tube instead of the metal thin film heater. For example, a film heater may have a structure in which a layer made of an electrical insulating material and a layer made of a heating track, which is an example of a heating element, are overlapped. Additionally, for example, it may have a structure in which a layer made of a heating track is disposed between the heater element 23, a layer made of two layers of electrical insulating material. The electrical insulating material may be, for example, polyimide, and the heating track may be metal, for example, stainless steel. Additionally, the heater region RH of the compression cylinder portion 63 may contain ceramic material. Examples of ceramic materials include alumina, aluminum nitride, and silicon nitride ceramic, and these may be laminated and sintered.

When the control unit 30 of the electric heating device 1 performs heating control of the hollow tube heater 21, it is installed on the heating wall RH of the hollow tube heater 21 by supplying power from the power source 40. When the heater element is energized, the heating wall portion RH generates heat, and as a result, the tobacco rod portion 110 of the cigarette stick 100 inserted into the heating chamber 60 can be heated from the outer peripheral side.

In this embodiment, the heater element 23 is disposed over the entire section in the axial direction of the compression cylinder portion 63 in the hollow tube heater 21, so that the heating wall portion RH is maintained over the section. It is formed. In the example shown in FIG. 6, the outer peripheral surface of the compression cylinder portion 63 extends from the upper end in the axial direction of the compression cylinder portion 63 to a position corresponding to the height of the positioning bottom surface 731 of the pedestal portion 73. The heater element 23 is installed to cover the heating wall portion RH in the corresponding area. However, the installation mode of the heater element 23 installed in the compression cylinder portion 63 is not particularly limited. That is, the heating wall portion RH may be formed over the entire length section of the compression cylinder portion 63, or may be formed only in a section shorter than the range shown in FIG. 6. Additionally, the heater element 23 in the compression cylinder portion 63 does not need to be installed on the outer peripheral side of the compression cylinder portion 63. For example, the heater element 23 may be embedded inside the wall of the compression cylinder portion 63 or may be disposed on the inner circumference side.

Here, FIG. 11 is a diagram showing a cross section (A-A cross section) at the A-A position of the hollow tube heater 21 shown in FIG. 6. FIG. 12 is a diagram showing a cross section (B-B cross section) at the B-B position of the hollow tube heater 21 shown in FIG. 6. The A-A cross section of the hollow tube heater 21 corresponds to the cross section of the insertion cylinder 5, and the B-B cross section corresponds to the cross section of the compression cylinder 63 in the chamber tube 6.

The compression cylinder portion 63 in the hollow tube heater 21 is configured to compress the tobacco rod portion 110 at least from the outer peripheral side when the tobacco stick 100 is inserted into the heating chamber 60. Hereinafter, when simply referring to the diameter of the cigarette stick 100 (cigarette rod portion 110, mouthpiece portion 120), it is the diameter when circular (before compression by the compression cylinder portion 63). The diameter is intended, and if the diameter of the cigarette stick 100 (cigarette rod portion 110, mouthpiece portion 120) is intended after compression by the compression cylinder portion 63, that effect is specified. do.

The insertion cylinder portion 5 of the hollow tube heater 21 has a relatively large internal cross-sectional area compared to the cross-sectional area of the cigarette stick 100 (cigarette rod portion 110 and mouthpiece portion 120). More specifically, the inner diameter of the insertion cylinder 5 is relatively larger than the diameter of the cigarette stick 100 (cigarette rod portion 110, mouthpiece portion 120). The symbol L1 shown in the A-A cross section of FIG. 6 represents the outer shape (contour) of the cigarette stick 100 in the cross-sectional direction when inserted into the insertion cylinder 5 of the hollow tube heater 21. As shown, a gap is formed between the inner wall surface 50 of the insertion cylinder 5 and the outline L1 of the cigarette stick 100. With this configuration, when the user inserts the cigarette stick 100 through the insertion hole 5A, the cigarette stick 100 can be smoothly inserted into the heating chamber 60. In addition, when the cigarette stick 100 is inserted into the heating chamber 60, a gap between the inner wall surface 50 of the insertion cylinder 5 and the cigarette stick 100 can be formed as an air flow path.

On the other hand, the compression cylinder portion 63 of the hollow tube heater 21 has a roughly oval (elliptical) cylinder shape as described above. Therefore, as shown in the internal hole cross-sectional view B-B in FIG. 6, the internal hole cross-section in the compressed cylinder portion 63 is formed as a roughly oval shape (elliptical shape). As long as the compression cylinder 63 connects a pair of opposing sandwiching wall portions 631, 631 extending along the axial direction of the compression cylinder 63, and the ends of each clamping wall portion 631, 631. It is formed by a pair of circular arc wall portions 632, 632. Here, the inner wall surfaces 631A and 631A of the pair of clamping wall portions 631 and 631 extend along the axial direction of the compressed cylinder portion 63 and are arranged to face each other in parallel. Additionally, the inner wall surfaces 632A and 632A of the pair of circular arc wall portions 632 and 632 extend along the axial direction of the compressed cylinder portion 63 and are arranged to face each other in parallel.

The distance between the inner wall surfaces 631A and 631A of a pair of interposing wall portions 631 and 631 is referred to as the “distance between intersecting wall surfaces D1”. The distance D1 between the clamping walls is set to a dimension smaller than the diameter of the cigarette stick 100 (cigarette rod portion 110, mouthpiece portion 120). In the B-B internal cross-sectional view of Fig. 6, the outer shape (contour) of the cigarette stick 100 in the cross-sectional direction when it is circular is indicated by symbol L2. In this embodiment, the cross-sectional area of the cigarette stick 100 (cigarette rod portion 110, mouthpiece portion 120) is relatively large compared to the internal cross-sectional area of the compression cylinder portion 63, and the compression cylinder portion 63 ) is specified so that the cigarette stick 100 (cigarette rod portion 110, mouthpiece portion 120) inserted into the cigarette is compressed by the inner wall surface of the compression cylinder portion 63. More specifically, the distance D1 between the clamping wall surfaces of the pair of opposing clamping wall portions 631, 631 in the compressed cylinder portion 63 is the same as that of the cigarette stick 100 (cigarette rod portion 110, mouthpiece). The dimension is set to be smaller than the diameter of the portion 120). Therefore, when the cigarette stick 100 is inserted into the compressed cylinder portion 63 of the hollow tube heater 21, the cigarette stick 100 is attached to the inner wall surface 631A of the pair of sandwiching wall portions 631, 631. , 631A) and is compressed from the outer circumference side. Furthermore, in this embodiment, when the cigarette stick 100 is inserted into the compression cylinder portion 63 of the hollow tube heater 21, the inner wall surfaces 632A and 632A of the pair of circular arc wall portions 632 and 632 and , the specification is such that a gap is formed between the main surface of the cigarette stick 100, but the specification may be such that the inner wall surfaces 632A, 632A are in contact with the main surface of the cigarette stick 100.

The distance D1 between the clamping walls of the compressed cylinder 63 is substantially equal to the minor axis dimension of the inner cross section of the compressed cylinder 63 having an approximately oval (elliptical) shape. Additionally, the major axis dimension of the internal hole cross section in the compressed cylinder portion 63 is not particularly limited. As an example, in this embodiment, the major axis dimension of the internal hole cross section in the compressed cylinder portion 63 is the same as the diameter of the cigarette stick 100 (cigarette rod portion 110, mouthpiece portion 120). However, the major axis dimension of the inner cross section of the compressed cylinder portion 63 may be set to a smaller dimension compared to the diameter of the cigarette stick 100 (cigarette rod portion 110, mouthpiece portion 120), or , it may be set to a large size.

FIG. 14 is a diagram illustrating a state in which the cigarette stick 100 is inserted to a specified position into the heating chamber 60 of the electric heating device 1 according to the embodiment. As shown in FIG. 14, the cigarette stick 100 inserted to the specified position in the heating chamber 60 has the tip 102 of the cigarette rod portion 110 positioned at the base portion 73 of the hollow tube heater 21. is positioned in contact with the bottom surface 731 for positioning, that is, the bottom surface of the heating chamber 60. Additionally, as shown in FIG. 14, in a state where the cigarette stick 100 is inserted to the specified position (positioning bottom 731) of the heating chamber 60, the mouthpiece portion 120 (cooling segment 121) ), the position (height) of the ventilation hole 103 coincides with the position (height) of the insertion port 5A.

Additionally, the axial direction of the compression cylinder portion 63 in the hollow tube heater 21 extends from the upper end of the compression cylinder portion 63 until it reaches the positioning bottom surface 731 in the pedestal portion 73. The length is larger than the length dimension of the tobacco rod portion 110. Therefore, in the cigarette stick 100 inserted to the specified position of the heating chamber 60 in the hollow tube heater 21, the entire cigarette rod portion 110 and a portion of the mouthpiece portion 120 are compressed into the cylinder portion 63. ) is inserted into. As a result, the entire tobacco rod portion 110 and a portion of the mouthpiece portion 120 are sandwiched between the inner wall surfaces 631A and 631A of the pair of sandwiching wall portions 631 and 631, so that they are positioned on the outer peripheral side. It is compressed from .

Then, when the operation button of the electric heating device 1 is turned on by a predetermined operation by the user, the control unit 30 starts supplying power from the power source 40 to the hollow tube heater 21, thereby cigarette smoking. Heating control for heating the tobacco rod portion 110 in the stick 100 is started. When heating control is started, the heater element 23 installed on the heating wall RH of the compressed cylinder portion 63 in the hollow tube heater 21 is energized, causing the heating wall RH to generate heat. As a result, the tobacco filling 111 included in the tobacco rod portion 110 of the cigarette stick 100 can be heated without burning, and vapor containing the aerosol generating base material and the tobacco flavor component can be generated.

The entire area of the compressed cylinder portion 63 of the hollow tube heater 21 according to the present embodiment in the axial direction is formed as a heating wall portion RH. Therefore, when operating the hollow tube heater 21, the tobacco rod portion 110 is heated in a state in which the tobacco rod portion 110 is compressed by the compression cylinder portion 63 (heating wall portion (RH)). You can. In this way, by compressing and heating the tobacco rod portion 110 from the outer peripheral side, the heat generated by the heating wall portion RH (heater element 23) can be efficiently transmitted to the tobacco filling 111 of the tobacco rod portion 110. . As a result, the tobacco filling 111 of the tobacco rod 110 is heated efficiently, thereby increasing the delivery amount of aerosol and flavor components.

Additionally, the tobacco rod portion 110 of the cigarette stick 100 is supported by the wrapper 112 in a state in which the tobacco filler 111 randomly orients the tobacco flesh. Therefore, the tobacco flesh is arranged in a uniformly dispersed state in the cross section of the tobacco rod portion 110, and the gap between the tobacco pieces can be reduced. As a result, even if the tobacco rod portion 110 is compressed from the outer circumference side upon insertion into the compression cylinder portion 63, it is possible to suppress a significant change in ventilation resistance during suction. In other words, it becomes difficult for each cigarette stick 100 to vary in ventilation resistance during suction, which contributes to ensuring stable quality for the flavor of the cigarette stick 100. That is, according to the cigarette stick 100 of the present embodiment and the non-combustion heated tobacco product provided therewith, it is possible to secure the delivery amount of the flavor component of the cigarette stick 100 and suppress the variation in ventilation resistance. there is.

In addition, the cross-sectional area of the tobacco rod portion 110 in the present embodiment after insertion into the compression cylinder portion 63 in the electric heating device 1 is 60% or more and 99% or less compared to the cross-sectional area before insertion. It is preferable that it is specified to be 80% or more and 98 or less. In addition, the diameter of the tobacco rod portion 110 is defined as a dimension of 105% or more and 200% or less with respect to the gap between the inner wall surfaces 631A and 631A in the pair of sandwiching wall portions 631 and 631. It is preferable, and it is more preferable that it is specified as a dimension of 109% or more and 140% or less. According to these, during operation of the hollow tube heater 21 in the electric heating device 1, the heat generated by the heating wall portion RH (heater element 23) is more efficiently generated by the tobacco rod portion 110. By delivering it to the tobacco filling 111, the tobacco filling 111 can be heated more efficiently. In addition, when the cross-sectional area of the tobacco rod portion 110 after insertion into the compression cylinder portion 63 in the electric heating device 1 is less than 60% based on the thickness before insertion, the There is a risk that the cigarette rod portion 110 may be excessively compressed upon insertion. As a result, there is a risk that the wrapper 112 may be torn when inserted into the compressed cylinder portion 63, or that suction may become difficult due to the ventilation resistance of the cigarette rod portion 110 becoming excessively large.

In addition, the vapor containing the aerosol generating base and the tobacco flavor component generated in the tobacco rod portion 110 when the hollow tube heater 21 is operated cools the mouthpiece portion 120 from the tobacco rod portion 110. It flows into the segment 121 and is cooled by contact with air blown into the cavity of the cooling segment 121 from the ventilation hole 103. In this way, the temperature of the ingredients or air flowing from the cigarette rod unit 110 can be lowered. Then, the vapor of the aerosol-generating substrate is liquefied by cooling in the cooling segment 121, thereby promoting the generation of aerosol. Then, the aerosol containing the flavor component passes through the filter segment 122 and is then sucked into the oral cavity from the suction end 101.

As described above, with the cigarette stick 100 inserted to the specified position in the heating chamber 60, the entire cigarette rod portion 110 and a portion of the mouthpiece portion 120 (cooling segment 121) are compressed. It is configured to be compressed by the inner wall surface of the cylinder portion 63 (inner wall surfaces 631A, 631A in the pair of sandwiching wall portions 631, 631). During operation of the hollow tube heater 21, not only the cigarette rod portion 110 of the cigarette stick 100 but also the mouthpiece portion 120 (cooling segment 121) is attached to the inner wall surface of the compression cylinder portion 63. By heating in a compressed state, it is possible to obtain the effect that it becomes difficult for vapor or aerosol to adhere to the inner wall of the mouthpiece portion 120 (cooling segment 121). In addition, the cross-sectional area of the mouthpiece portion 120 is preferably defined so that the cross-sectional area after insertion into the compression cylinder portion 63 is 60% or more and 99% or less compared to before insertion, and is 80% or more and 98% or less. It is more desirable to specify that . As a result, the above-mentioned effect of suppressing adhesion of vapor or aerosol can be more significantly achieved. Additionally, in the case where the cross-sectional area of the mouthpiece portion 120 after insertion into the compression cylinder portion 63 of the electrically heated device 1 is less than 60% of the area before insertion, the There is a risk that the mouthpiece portion 120 may be excessively compressed upon insertion. As a result, there is a risk that the mouthpiece portion 120 may be damaged when inserted into the compression cylinder portion 63. Conversely, when the cross-sectional area of the mouthpiece 120 after insertion into the compression cylinder 63 exceeds 99% of the area before insertion, the adhesion between the mouthpiece 120 and the hollow tube heater 21 As this decreases, there is a risk that it will become difficult to fully achieve the effect of making it difficult for vapor or aerosol to adhere to the inner wall of the mouthpiece portion 120.

In addition, when the tobacco stick 100 is inserted into the heating chamber 60 of the hollow tube heater 21 in the electric heating device 1, a pair of sandwiching wall portions 631 in the compression cylinder portion 63 , 631) and is inserted into the specified position (positioning bottom 731) of the heating chamber 60 while receiving resistance. That is, in this embodiment, even before the tip 102 of the cigarette stick 100 comes into contact with the positioning bottom surface 731 of the heating chamber 60, the insertion resistance is increased due to contact with the clamping wall portions 631 and 631. Because this occurs, the user can determine the moment when the tip 102 of the cigarette stick 100 touches the positioning bottom 731 of the heating chamber 60 from the change in the insertion resistance of the cigarette stick 100. It gets difficult.

In contrast, the cigarette stick 100 has a mouthpiece portion ( The position (height) of the ventilation hole 103 provided in 120 (cooling segment 121) is specified to match the position (height) of the insertion port 5A of the heating chamber 60. Accordingly, the user can, based on the relative position between the position (height) of the ventilation hole 103 and the position (height) of the insertion port 5A when inserting the tobacco stick 100 into the heating chamber 60, It is easy to visually determine when the insertion operation will stop. That is, when inserting the cigarette stick 100 into the heating chamber 60, the position of the ventilation hole 103 is used as a mark, and the position (height) of the ventilation hole 103 is the position of the insertion port 5A ( The moment when the tip 102 of the cigarette stick 100 touches the positioning bottom surface 731 of the heating chamber 60 at the time when it is visually confirmed that the height matches the height, the moment the cigarette stick 100 is inserted It can be determined without relying on changes in resistance.

As a result, when inserting the cigarette stick 100 into the hollow tube heater 21 in the electric heating device 1, the position of the ventilation hole 103 in the cigarette stick 100 is that of the insertion port 5A. By simply inserting the cigarette stick 100 until it matches the height, the cigarette stick 100 can be accurately inserted to the specified position. And, because the timing at which the cigarette stick 100 was inserted into the specified position can be properly determined, even though the tip 102 of the cigarette stick 100 is in contact with the positioning bottom surface 731 of the heating chamber 60 , it is possible to prevent an attempt to push the cigarette stick 100 further into the heating chamber 60 from that state. Thereby, it is possible to prevent the cigarette stick 100 from buckling or being distorted in the axial direction. In addition, when inserting the cigarette stick 100 into the heating chamber 60 of the hollow tube heater 21, the user exerts insertion resistance due to contact between the cigarette stick 100 and the clamping wall portions 631 and 631 to insert the cigarette. It is also possible to prevent the insertion operation of the cigarette stick 100 from stopping before the specified position due to confusion with the tip 102 of the stick 100 coming into contact with the positioning bottom 731 of the heating chamber 60. .

In addition, the ventilation hole 103 for introducing external air into the cooling segment 121 of the mouthpiece unit 120 is located on the upstream side of the cooling segment 121 (tobacco rod unit 110 side). When the cigarette stick 100 is inhaled, the cooling effect of the vapor of volatile components emitted from the heated tobacco filling 111 is significant. On the other hand, when the cigarette stick 100 is sucked, if the ventilation hole 103 is located within the heating chamber 60 (the area surrounded by the wall of the hollow tube heater 21 below the insertion port 5A), when the tobacco stick 100 is sucked, It becomes difficult to smoothly introduce external air into the mouthpiece portion 120 (cooling segment 121) through the ventilation hole 103. In contrast, the cigarette stick 100 of the present embodiment has the mouthpiece portion 120 in a state in which the cigarette stick 100 has been inserted to the specified position (positioning bottom 731) of the heating chamber 60. Since the position (height) of the ventilation hole 103 (of the cooling segment 121) matches the position (height) of the insertion port 5A of the heating chamber 60, the cooling segment 121 during suction It is possible to achieve both the cooling effect and the efficiency of blowing in external air through the ventilation hole 103. In other words, from the viewpoint of achieving both the cooling effect of the cooling segment 121 during suction and the efficiency of taking in outside air through the ventilation hole 103, the position of the ventilation hole 103 in the cigarette stick 100 and , the insertion depth of the heating chamber 60 can be defined in an optimal relative relationship.

In addition, the cigarette stick 100 in the present embodiment has a lip release region R1 located between the mouth end 101 of the mouthpiece 120 and the ventilation hole 103 (FIGS. 1 and 2). 14, etc.), the outer surface of the chip paper 130 is covered with a lip release material. In this embodiment, the tip 102 of the cigarette rod portion 110 (cigarette stick 100) is positioned at the lip release material arrangement region R1 where the lip release material is disposed at a defined position ( When inserted up to the positioning bottom surface 731 (the innermost position), it is defined as an area located at least on the insertion port 5A side rather than the heating wall portion RH of the compression cylinder portion 63. According to this, when the heating wall portion RH of the compression cylinder portion 63 generates heat due to the operation of the hollow tube heater 21 in the electric heating device 1, the lip release material arrangement in the cigarette stick 100 It is possible to suppress the lip release material in the region R1 from being directly heated by the heating wall portion RH. As a result, components that may affect the flavor of the tobacco stick 100 can be suppressed from being released from the lip release material. In this embodiment, in particular, the lip release material arrangement area R1 is defined as an area located between the mouth end 101 of the mouthpiece portion 120 and the ventilation hole 103. As described above, the ventilation hole 103 of the mouthpiece portion 120 is such that the tip 102 of the cigarette stick 100 is positioned at a specified position (positioning bottom 731, innermost position) of the heating chamber 60. ), it is specified to match the position (height) of the insertion port 5A of the heating chamber 60. Therefore, by setting the range of the lip release material arrangement area R1 in the cigarette stick 100 as described above, when the cigarette stick 100 is inserted to the innermost position of the heating chamber 60, the lip release The material placement area R1 can be positioned more reliably on the insertion port 5A side than the heating wall portion RH of the compression cylinder portion 63.

Here, an example of a method for quantifying the application amount of the lip release material on chip paper will be described. The instruments used in this quantitative method include a rotary evaporator, constant temperature water bath, cooling pipe, and absorbance measurement device. First, a sample of chip paper coated with a lip release material is prepared, and the sample is placed in a previously weighed Erlenmeyer flask to weigh the sample (step 1). Next, 100 ml of acetone as a reagent is added to the Erlenmeyer flask, and ultrasonic extraction is performed for 30 minutes (step 2). Next, the extract extracted in step 2 is transferred to a 300 ml eggplant flask, and the acetone in the extract is volatilized using a rotary evaporator (step 3). In step 3, volatilization of acetone is performed with the eggplant-shaped flask set so that it is submerged in a constant temperature water bath set to a water temperature of 40°C. Next, 25 ml of acetone is added to the eggplant-shaped flask in several portions, and the non-volatile substances remaining in the flask are dissolved again (step 4). Next, 50 ml of the solution in which the non-volatile matter was dissolved again in step 4 is transferred to another eggplant-shaped flask, and then the acetone in the solution is volatilized using an evaporator (step 5). Next, 10 ml of acetone and 10 ml of 10% KOH were added to the eggplant-shaped flask containing the solution in which acetone was volatilized in step 5, and a cooling tube was set in the eggplant-shaped flask, followed by refluxing for 1 hour in a constant temperature water bath at a water temperature of 60°C. Carry out (step 6). Next, the solution is cooled to room temperature on ice and then filtered using filter paper (step 7). For filtration in step 7, 50 ml of the filtrate was placed in a volumetric flask, and the volumetric flask was filled up to the line with a mixed solution of acetone and water (acetone:water = 2:1). Next, the absorbance of the solution filtered in step 7 is measured using an absorbance measuring device.

The embodiments related to the present invention have been described above, but each configuration and combination thereof in the embodiments are examples, as appropriate, without departing from the main spirit of the present invention. Additions, omissions, substitutions, and other changes to the configuration are possible. For example, if the cross-sectional area of the compressed cylinder portion 63 in the hollow tube heater 21 of the electric heating device 1 is relatively small compared to the cross-sectional area of the tobacco stick 100, the compressed cylinder portion 63 may be compressed in a specific embodiment. There is no particular limitation on this. Therefore, in the above embodiment, an embodiment in which the compressed cylinder portion 63 includes a pair of sandwiching wall portions 631 and 631 opposed in parallel along the axial direction has been described as an example, but instead of this, a non-parallel An aspect in which the cigarette stick 100 inserted into the compression cylinder 63 is compressed from the outer circumference side by sandwiching the cigarette stick 100 between the wall parts may be adopted.

Additionally, the compressed cylinder portion 63 in the hollow tube heater 21 may be a cylindrical body having an inner diameter smaller than the diameter of the cigarette stick 100. In this case, the constriction cylinder 62 located between the connection cylinder 61 and the compression cylinder 63 in the chamber tube 6 is connected to the compression cylinder 63 from the upper end side connected to the connection cylinder 61. The inner diameter may be gradually reduced to a tapered shape toward the lower end where it is connected to. In either of the above aspects, the cigarette stick 100 can be compressed from the outer circumference side by the inner wall surface of the compression cylinder portion 63, and the cigarette stick 100 is compressed when the hollow tube heater 21 is operated. Compression heating becomes possible.
