Abstract

A support for a incense core capable of stabilizing the flow of aerosol in the incense core is provided. A flow channel (301) (flow channel 301A-flow channel 301D) for the through-flow of aerosol passing from the inlet end (300A) toward the outlet end (300B) is provided in the wick support (300). Further, an alternating current space (302) for causing the flow of the aerosol from the aerosol-generating member (110) shown in fig. 1 and 2(a) to the support member (300) to be alternating current is provided at the inlet end of the flow passage (301) of the support member (300). The alternating current space section (302) uniformizes the flow rate and flow velocity of the aerosol from the aerosol generating member (110) toward the support member (300) due to the type and filling amount of the base material (110A) of the aerosol generating member (110), and facilitates the inhalation of the fragrance component from the aerosol generating member (110) by the user.

Description

Support member for incense core and incense core having the same

Technical Field

The present invention relates to a wick support member to be attached to a heating type incense burner and a wick having the same.

Background

In recent years, electronic smoking articles are becoming popular (for example, patent documents 1 and 2), which are in line with the smoke suppression tendency and which vaporize tobacco components to inhale them by heating a cartridge containing the tobacco components without a flame.

The electronic cigarette of patent document 1 generates an aerosol containing a tobacco component by inserting a heating element into an aerosol-forming substrate of a cartridge and heating the aerosol-forming substrate. The cartridge has a hollow tubular support supporting the aerosol-forming substrate, the support being subjected to a force to which the cartridge is subjected when the heating element is inserted into the aerosol-forming substrate. Aerosols of tobacco components released from the aerosol-forming substrate by heating pass through the hollow of the support and are sent to a downstream located mouthpiece for inhalation by a user.

Patent document 2 discloses a device for heating a smoking material and an aerosol-cooling member used therefor. The aerosol-cooling member described in patent document 2 is, for example, a one-piece rod having a first end portion and a second end portion, and having a plurality of through holes extending between the first and second end portions.

Disclosure of Invention

Problems to be solved by the invention

The electronic cigarette of patent document 1 has a problem that it is difficult for a user to inhale a fragrance component due to, for example, unevenness in clogging of a filler as a base material in an aerosol-forming base material. For example, due to the unevenness of clogging in the longitudinal direction of the filler and the unevenness in the cross section perpendicular thereto, the flow rate and the flow velocity of the aerosol of the tobacco component released by heating change with time when the aerosol moves toward the support member, and therefore, in addition to the unevenness with time or the time difference, the aerosol has a large flow rate and a high flow velocity only in the through hole region as compared with other portions, and the flow rate from the other regions is small and the flow velocity is low, so that it is difficult to inhale the aromatic component at a uniform flow rate and flow velocity.

Similarly, the aerosol cooler described in patent document 2 has a problem that since a plurality of through holes having the same diameter extend straight between the first end and the second end of the monolith rod, the flow of aerosol in the aerosol cooler tends to become unstable. In the respective plural through holes (flow channels), there is a similar time difference with respect to the individual flow channels, and in addition, there is a difference in place between the flow channels, so that it is difficult to suck the aromatic components in a stable state.

Further, in the electronic cigarette of patent document 1, in addition to being difficult to inhale, there is a problem that the inside of the aerosol-forming substrate is subjected to an excessively high load when the heating element is inserted into the aerosol-forming substrate. In this case, too high a load may make the insertion difficult, and the cartridge may be bent during the insertion, and the heating element itself may be broken.

The present invention has been made to solve the above-described problems of the prior art, and an object of the present invention is to provide a holder for a replaceable cartridge of an electronic cigarette, which can stabilize the flow of aerosol in the replaceable cartridge of the electronic cigarette.

Further, another object of the present invention is to provide a support member which, while ensuring a flow path for transporting an aerosol within an electronic cigarette cartridge, also stably supports an aerosol-forming substrate upon insertion of a heating element, while not causing defects within the cartridge due to insertion of the heating element, and without causing problems with the electronic cigarette itself.

It is a further object of the present invention to facilitate insertion of a cartridge when using an electronic cigarette, thereby improving operability.

Means for solving the problems

Hereinafter, in the present invention, the electronic cigarette and the electronic cigarette replaceable cartridge are referred to as a heating type fumigator and a wick, respectively.

Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. In the following description, the ranges necessary for explaining the objects of the present invention are shown by modes, and the ranges necessary for explaining the portions of the present invention are mainly explained, and the descriptions are omitted based on the known techniques.

Fig. 1 shows one usage form of the incense core of the present embodiment. The wick 100 is mounted to the heating type fumigator main body 200 when the user uses it. The heating type incense device main body 200 is provided with an insertion port 210 into which the incense core 100 is inserted.

A heating element 211 is provided in the heating type fumigator main body 200. The heating element 211 has a needle-like or blade-like member with a sharpened front end, and is inserted into the aerosol-generating member 110 of the incense wick 100 and heats the aerosol-generating member 110. Specifically, the heating element 211 pierces a substantially central portion of the aerosol generating member 110 when the wick 100 is inserted into the insertion port 210 of the heated fumigator main body 200. In the illustrated example, the heating element 211 may have one or more pointed or blade-like portions.

The heating element 211 directly generates heat or indirectly generates heat by electric power supplied from a battery (not shown) built in the heating type fumigator main body 200. The aerosol-generating member 110 is heated by the heat generation of the heating element 211, thereby generating an aerosol containing a fragrant component.

The generated aerosol is then sent to the filter 130 also serving as a mouthpiece through the support member 300 and the transport member 120 in the incense core 100 described below, and is inhaled from the filter 130 side by the user, whereby the aromatic components reach the oral cavity of the user.

FIG. 2(A) shows an example of the structure of the incense core 100 shown in FIG. 1. In the incense core 100, the aerosol-generating member 110, the support member 300, the conveying member 120, and the filter member 130 are arranged in this order from the side where the heating element 211 (fig. 1) is inserted.

The support 300, which is arranged adjacent to the aerosol-generating member 110, is a member that supports the aerosol-generating member 110, with its sides meeting the peripheral member 140 provided at the periphery of the incense wick 100. The outer peripheral member 140 is a member for packing the incense core 100, and is integrally formed so as to cover the outer periphery of the incense core 100.

The support 300 is suitably made of, for example, silicone, but is not limited to silicone, and other materials excellent in heat resistance may be used. The transport element 120 is a member having a function for cooling the aerosol sent from the support 300 to the filter element 130.

As shown in fig. 2(B), instead of extending the filter member 130 without the delivery member 120, the filter member 130 may have an aerosol cooling function. Thus, the ventilation property in the incense core 100 is improved, the aromatic components in the aerosol can be easily absorbed, and the number of parts of the incense core 100 can be reduced.

Further, as shown in fig. 2(C), by providing the baffle 170 between the aerosol-generating member 110 and the support member 300, it is possible to avoid a problem that the aerosol-generating member 110 moves in the incense core 100 due to vibration during transportation or the like. The material of the barrier 170 is, for example, a material that is damaged when the heating element is inserted into the aerosol-generating device 110 (fig. 1), such as paper or a filter material having good air permeability.

As shown in fig. 2(D), a cap 180 may be provided on the side of the aerosol generating member 110 into which the heating element 211 (fig. 1) is inserted. Accordingly, while the escape of the aromatic component in the aerosol-generating member 110 can be suppressed, the disadvantage that the aerosol-generating member 110 falls off the incense core 100 due to vibration during transportation or the like can be avoided. Examples of the material of the cap 180 include paper, filter material, and sponge. Furthermore, by providing one or more cut-outs in a portion of the cover 180, insertion of the heating element 211 into the aerosol generating member 110 (fig. 1) is facilitated by providing circular or polygonal guide holes. As shown in fig. 2(E), the aerosol-cooling function may be provided to the support 300 by extending the support 300 in the configuration of fig. 2 (B).

As shown in fig. 3, it is preferable that the base material 110A constituting the aerosol-generating member 110 is filled with a material having a rod-like or rectangular shape along the longitudinal direction of the aerosol-generating member 110, so that the aerosol airflow is stabilized and the inhalation of the fragrant component by the user is facilitated.

Fig. 4 shows a state in which the side portions (outer circumferential portions) of the aerosol-generating material 110, the carrier 300, the conveyor 120, and the filter 130 shown in fig. 2 a are wound into a rod shape by an outer circumferential material 140 such as cigarette paper. The outer peripheral member 140 is fixed to the respective sides of the aerosol-generating member 110, the support member 300, the transport member 120, and the filter member 130, for example, by an adhesive. As the base material 110A constituting the aerosol-generating member 110, the following non-tobacco plants were used.

The detailed structure of the support member 300 of the incense core 100 shown in FIGS. 1 and 2(A) to 2(E) will be described below. Although the following embodiment describes an example in which the incense core 100 has the structure shown in fig. 2(a), the structure of the support member 300 can be applied to the case where the incense core 100 has the structure shown in fig. 2(B) to 2 (E).

First embodiment

The support 300 of the present embodiment has the following features as shown in fig. 5. The support member 300 has an inlet end 300A (see fig. 5(a)) on the aerosol-generating member 110 side as shown in fig. 1 and 2(a) and an outlet end 300B (see fig. 5(B)) on the transport member 120 side.

A flow passage 301 (flow passage 301A to flow passage 301D) through which aerosol passing from the inlet end 300A to the outlet end 300B flows is provided in the cylindrical side portion (outer circumferential portion) of the support 300. The number of the flow paths 301 is four in the illustrated example, but may be three or less or five or more.

The four flow paths 301A to 301D are constituted by a plurality of flow paths having different cross-sectional areas from each other. In the illustrated example, the cross-sectional areas of the

flow channels

301A and 301C are smaller than the cross-sectional areas of the

flow channels

301B and 301D.

At an inlet end 300A of the flow passage 301 of the holder 300, an alternating current space portion 302 for allowing an aerosol to flow through and communicate from the aerosol-generating member 110 toward the holder 300 as shown in fig. 1 and 2(a) is provided. Specifically, a step (inlet end position difference) is provided between the inlet end 300A of the support 300 and the inlet end of the flow channel 301 (see fig. 5 a), and the ac space 302 is formed by an inlet end space formed by the step. On the other hand, a flat continuous surface having no step (outlet end position difference) is formed between the outlet end 300B of the support 300 and the outlet end of the flow channel 301 (see fig. 5B).

The flow path 301 and the ac space 302 are formed in the incense core 100 by a space portion where the outer peripheral member 140 (see fig. 2 a) is not filled with the constituent material of the support member 300. Further, an outer peripheral member forming only a part of the outer periphery of the support member 300 may be formed integrally with the support member 300.

In this way, by providing the alternating-current space section 302 for allowing the aerosol to flow through alternating current at the inlet end 300A of the flow passage 301 of the support 300, the aerosol from the aerosol-generating member 110 toward the support 300 temporarily stays in the alternating-current space section 302 in terms of time and space, and then flows into the flow passages 301A to 301D.

This provides an effect that the aerosol is uniformized in the ac space portion 302 even when the time and place are different due to the unevenness in the flow rate and the flow velocity of the aerosol from the aerosol-generating member 110 toward the support member 300 caused by the type, the filling amount, and the like of the base material 110A of the aerosol-generating member 110, and thereby the aerosol flow through the support member 300 is stabilized, and the user can easily inhale the fragrant component from the aerosol-generating member 110.

As described above, in the present embodiment, since the cross-sectional areas of the flow passages 301A to 301D are made different from each other, the flow rate and the flow velocity of the aerosol flowing through the support 300 vary for each of the flow passages 301A to 301D. This has the effect that the through-flow of aerosol through the support 300 and towards the transport element 120 becomes more stable.

Also, in the case where the ac space portion 302 is provided at the inlet end of the flow path of the supporter 300, when the heating element 211 provided in the heating type fumigator main body 200 shown in fig. 1 is inserted into the aerosol-generating member 110, an excessive load applied to the aerosol-generating member 110 by the heating element 211 can be reduced.

In the present embodiment, the ac space 302 is formed by an inlet end space formed by a step difference between the inlet end 300A of the support 300 and the inlet end of the flow channel 301, but the ac space 302 may be formed by an outlet end space formed by a step difference provided between the outlet end 300B of the support 300 and the outlet end of the flow channel 301. Further, the ac space portion 302 may be formed at both the inlet end 300A side and the outlet end 300B side of the supporter 300.

Fig. 6 shows an example in which a restricting member 150 for restricting the passage region of aerosol from the support member 300 toward the transport member 120 (refer to fig. 1 and 2(a)) is provided at the inlet end 300A of the support member 300.

The stopper 150 is formed of a thin plate having a plurality of small-sized openings 151 for allowing the aerosol to pass therethrough, and is fitted into the ac space 302 of the holder 300. When the restriction member 150 is fitted into the ac space portion 302, one or more protrusions 303 supporting the restriction member 150 are provided on the inlet end 300A side of the support member 300, and the ac space portion 302 occurs between the restriction member 150 and the inlet end of the flow passage 301.

By providing the stopper 150, it is possible to prevent a defect that a part of the base material 110A of the aerosol-generating member 110 leaks out on the side of the support 300 and is inhaled by the user.

Further, the stopper 150 may be provided flush with the inlet end 300A, but may be provided at an intermediate position in the depth direction of the ac space portion 302 by height adjustment of the plurality of protrusions 303. At this time, slight protrusion (bulging) of the base material 110A of the aerosol-generating member 110 which occurs when the heating element 211 penetrates is easily allowed without becoming overloaded.

Although the restriction member 150 may be provided on the outlet end 300B side of the support member 300, it is preferably provided in the ac space portion 302 in view of easy attachment.

In the example shown in fig. 5, the inlet-end space portion formed by the step difference (inlet-end position difference) between the inlet end 300A of the support 300 and the inlet end of the flow channel 301 is the alternating-current space portion 302, but as shown in fig. 7, it is also possible to provide an inclination between the inlet end 300A of the support 300 and the inlet end of the flow channel 301, and the inlet-end space portion formed by this inclination is the alternating-current space portion 302.

Fig. 7(a) shows an example in which the outermost periphery of the inlet end 300A of the support member 300 is inclined toward the center, and fig. 7(B) shows an example in which the outermost periphery of the inlet end 300A is formed in a flat surface and is inclined toward the center from the inner side thereof, but in any case, the same effect as in the example shown in fig. 5 can be obtained. Here, although illustration is omitted, in the form shown in fig. 7, the restricting member 150 that restricts the aerosol passage region may be provided at the inlet end 300A of the support member 300 as in the form shown in fig. 6. In this case, by using the inclination in fig. 17 and 19 as in the following example, the protrusion 303 in fig. 6 may not be provided, and the alternating-current space portion 302 may also occur between the restriction member 150 and the inlet end of the flow passage 301. Further, by using the inclination, it is possible to easily set the ac space portion 302 at the middle position in the depth direction as well as flush with the entrance end 300A.

An example of the dimensions of the support 300 shown in fig. 5 is shown in table 1. The dimensions of the support member 300 shown in table 1 are an example of the optimum dimensions, but are actually obtained as a function of the type and number of the substrates 110A of the aerosol-generating member 110, and the like. Here, the material of the support 300 is composed of silicone and has a diameter of 6.93 mm. The diameters of the

flow paths

301B and 301D are 2.50 mm, respectively, and the diameters of the

flow paths

301A and 301C are 2.20 mm, respectively.

TABLE 1

Second embodiment

The support member 400 of the present embodiment has the following features as shown in fig. 8. The support member 400 has an inlet end 400A (see fig. 8 a) on the aerosol-generating member 110 side as shown in fig. 1 and 2 a and an outlet end 400B (see fig. 8B) on the transport member 120 side.

A flow passage 401 (flow passage 401A-flow passage 401D) through which aerosol flows from the inlet end 400A toward the outlet end 400B is provided in the support 400. The number of the flow passages 401 penetrating the support 400 is four in the illustrated example, but may be three or less or five or more.

The four flow paths 401A to 401D are constituted by a plurality of flow paths having different cross-sectional areas from each other. In the illustrated example, the cross-sectional areas of the

flow channels

401A and 401C are smaller than the cross-sectional areas of the

flow channels

401B and 401D.

At the inlet end of the flow channel 401 of the holder 400, an alternating current space 402 is provided for allowing an aerosol to flow through and communicate from the aerosol-generating member 110 to the holder 400 as shown in fig. 1 and 2 (a). Specifically, a step (inlet end position difference) is provided between the inlet end 400A of the support 400 and the inlet end of the flow channel 401 (see fig. 8 a), and the ac space 402 is formed by an inlet end space formed by the step. On the other hand, a flat continuous surface having no step (outlet end position difference) is formed between the outlet end 400B of the support 400 and the outlet end of the flow channel 401 (see fig. 8B).

This provides an effect that the aerosol flow-through is stabilized by providing the alternating-current space 402 for allowing the aerosol to flow through the alternating-current space at the inlet end of the flow passage 401 of the holder 400, and the user can easily inhale the fragrant components from the aerosol-generating member 110.

In the present embodiment, the alternating-current space portion 402 is formed by an inlet end space portion formed by a step difference between the inlet end 400A of the support 400 and the inlet end of the flow channel 401, but the alternating-current space portion 402 may be formed by an outlet end space portion formed by a step difference provided between the outlet end 400B of the support 400 and the outlet end of the flow channel 401. In addition, the ac space 402 may be formed on both the inlet end 400A side and the outlet end 400B side of the support 400.

Fig. 9 shows an example in which a restricting member 160 for restricting a passage area of aerosol from the support member 400 toward the transport member 120 (refer to fig. 1 and 2(a)) is provided at the inlet end 400A of the support member 400.

The restricting member 160 is formed of a thin plate having a minute-sized opening 161 that allows the aerosol to pass therethrough, and is fitted into the ac space portion 402 of the holder 400. When the restriction member 160 is fitted into the ac space part 402, one or more protrusions 403 (fig. 9(B)) supporting the restriction member 160 are provided on the inlet end 400A side of the support member 400, and the ac space part 402 is present between the restriction member 160 and the inlet end of the flow passage 401. By providing the restriction member 160, a defect that a part of the base material 110A of the aerosol-generating member 110 leaks out to the support member 300 side can be prevented.

The stoppers 160 may be provided flush with the inlet end 400A, as with the stoppers 150, or may be provided at an intermediate position in the depth direction of the ac space 402, so that the slight protrusion (bulge) of the base material 110A generated when the heating element 211 penetrates can be easily allowed, in addition to preventing the base material 110A from coming off and moving.

The stopper 160 may be provided on the outlet end 400B side of the support member 400, that is, on the ac void part 402 side, but is preferably provided in the ac void part 402 in view of easy attachment.

In the example shown in fig. 8, the inlet-end space formed by the step difference (inlet-end position difference) between the inlet end 400A of the support 400 and the inlet end of the flow channel 401 is the ac space 402, but as shown in fig. 10, an inclination may be provided between the inlet end 400A of the support 400 and the inlet end of the flow channel 401, and the inlet-end space formed by the inclination may be the ac space 402. Although not shown, the restricting member 160 may be provided at the inlet end 400A or the outlet end 400B of the support member 400 in the embodiment shown in fig. 10, as in the embodiment shown in fig. 9. In this case, since the inclination is used, the alternating current space 402 can be generated between the stopper 160 and the inlet end of the flow path 401 without providing the protrusion 403 in fig. 9, and since the inclination is used, the alternating current space can be easily provided not only flush with the inlet end 400A but also at an intermediate position in the depth direction of the alternating current space 402.

Third embodiment

As shown in fig. 11, the support member 500 of the present embodiment has an inlet end 500A on the aerosol-generating member 110 side as shown in fig. 1 and 2(a) and an outlet end 500B on the transport member 120 side. Further, a flow passage 501 through which the aerosol passes from the inlet end 500A to the outlet end 500B is provided in the support 500.

As shown in fig. 11(a), an alternating-current space 502 for restricting an aerosol passage region is provided in the middle of the flow channel 501 of the support 500. Specifically, a step is provided in the middle of the flow channel 501, and the ac space 502 is formed by a middle space formed by the step.

By providing the alternating-current space portion 502 for allowing the aerosol to flow in alternating current in the middle of the flow passage 501 of the holder 500, the aerosol flow through the holder 500 is stabilized, and the user can easily inhale the fragrant components from the aerosol-generating member 110.

As shown in fig. 11(B), in the supporter 500 of the present embodiment as well, similarly to the first and second embodiments, by providing the stopper 160 having the plurality of openings 161 in the ac space portion 502, it is possible to prevent a defect that a part of the base material 110A of the aerosol-generating material 110 leaks out to the supporter 500 side. The restricting member 160 may also be disposed adjacent to the aerosol-generating member 110 (refer to fig. 1 and 2) on the inlet end 500A side of the supporting member 500.

In the example shown in fig. 11, the alternating current space 502 is defined as a space formed by a step in the middle of the flow path 501, but as shown in fig. 12, the alternating current space 302 may be defined as a space formed by an inclination in the middle of the flow path 301.

In the case of the form of the first embodiment shown in fig. 5, the outer peripheral side of the inlet end 300A of the support member 300 protrudes further toward the aerosol-generating member 110 than the center side, but as shown in fig. 13(a), a structure is also possible in which the center side of the inlet end 300A of the support member 300 protrudes further toward the aerosol-generating member 110 than the outer peripheral side.

Similarly, in the case of the form shown in fig. 7 of the first embodiment, the outer peripheral side of the inlet end 300A of the holder 300 protrudes further toward the aerosol-generating member 110 than toward the center, but as shown in fig. 13, a structure is also possible in which the center of the inlet end 300A of the holder 300 protrudes further toward the aerosol-generating member 110 than toward the outer peripheral side.

The shape of the

support

300, 400, 500 is not limited to the shape defined in the above example, and various design changes are possible. For example, as shown in fig. 14 and 15, the support member 300 may have a spherical outer periphery of the inlet end 300A. The outer peripheral side of the inlet end 300A protrudes more toward the aerosol-generating member 110 than toward the center in the support 300 shown in fig. 14, and the center of the inlet end 300A protrudes more toward the aerosol-generating member 110 than toward the outer peripheral side in the support 300 shown in fig. 15.

Fourth embodiment

In the first to third embodiments, the form in which four flow paths are provided on the support member is explained, but in the present embodiment, the form in which 1 or 2 flow paths are provided on the support member while an alternating-current space portion is provided at the inlet end of the support member is described. In all the drawings for describing the following embodiments, components having the same functions are denoted by the same reference numerals in principle, and redundant description thereof will be omitted.

In fig. 16, there are shown oblique, front, side and bottom views of one form of the support 600. Fig. 16 is a form in which a flow channel 601 is provided at the center of a cylindrical bearing member 600, an inclination is provided between the inlet end of the bearing member 600 and the inlet end of the flow channel 601, and an inlet end space portion formed by the inclination is an alternating current space portion 602.

Fig. 17 shows a form in which a restricting member 190 for restricting a passage region of aerosol from the support member 600 toward the transport member 120 (refer to fig. 1 and 2(a)) is provided at the inlet end of the support member 600 shown in fig. 16. Fig. 17(a) shows an example in which the regulating member 190 is provided at the outermost periphery of the inlet end of the support member 600, and fig. 17(B) shows an example in which the regulating member 190 is provided at a position closer to the central portion (the flow passage 601) than the outermost periphery of the inlet end of the support member 600.

The stopper 190 may be a thin plate provided with a plurality of small-sized openings 191 that allow the aerosol to pass therethrough (fig. 17C), or may be a member having a lattice-shaped frame 192 (fig. 17D). In the case of the restricting member 190 shown in fig. 17(D), the function for restricting the passing region of the aerosol from the aerosol-generating member 110 toward the support member 600 is weak, so that an effect of reducing the excessive load that the heating element 211 gives to the aerosol-generating member 110 when the heating element 211 provided in the heated fumigator main body 200 shown in fig. 1 is inserted into the aerosol-generating member 110 is obtained.

The central portion 193 is fixed in the flow path 601 by a fixing portion 194 formed integrally with the central portion 193, and the flow path 601 is formed in a gap between the inner peripheral surface of the bearing 600 and the central portion 193.

In the embodiment shown in fig. 32, the inlet end of the support 600 protrudes further on the aerosol-generating member 110 (fig. 1 and 2(a)) side than the end of the central portion 193, but like the form shown in fig. 33, the end of the central portion 193 may also protrude further on the aerosol-generating member 110 side than the inlet end of the support 600.

In the present embodiment, an alternating-current space portion 602 for allowing aerosol to flow through alternating current is provided at the inlet end of the flow channel 601 of the support 600, and thus aerosol heading from the aerosol-generating member 110 to the support 300 temporarily stays in the alternating-current space portion 302 for a certain time and space and then flows into the flow channel 601.

Accordingly, the conventional time-varying unevenness, time difference, or area unevenness caused by the time-varying changes in the flow rate and flow velocity of the aerosol due to the unevenness caused by the clogging state of the filler as the base material in the aerosol-forming base material is uniformized by the ac space portion 602. This achieves the effect that the aerosol through-flow through the support 600 becomes stable and it becomes easy for the user to inhale the fragrance composition from the aerosol generating member 110.

In addition, in order to solve the conventional problem that the aerosol-forming substrate is subjected to an excessive load when the heating element is inserted into the aerosol-forming substrate, in addition to the difficulty in inhalation, the flow path for transporting the aerosol in the heating type incense core is ensured, and the excessive load is prevented by stably supporting the aerosol-forming substrate when the heating element is inserted, thereby achieving the effect that the insertion of the heating element becomes easy and the operability can be improved.

The present invention made by the present inventors has been specifically described above based on embodiments thereof, but the present invention is not limited to the embodiments, and it goes without saying that various modifications are possible without departing from the gist thereof.
