Air passing through the upstream passage portion 21a flows into the load passage portion 22 through the hole 72c, and air passing through the upstream passage portion 21b flows into the load passage portion 22 through the hole 72d.

In this embodiment, the direction of air flow in the upstream passage portions 21 a and 21 b is opposite to the direction of air flow in the downstream passage portion 23 . Specifically, in the present embodiment, the direction of air flow in the upstream passage portions 21a and 21b is the -Z direction, and the direction of air flow in the downstream passage portion 23 is the Z direction.

2, 3A and 3B, wall portions 70b, 70c, 70e, 70f, 70g, 71a and There is a space separated by 71b. The space is partitioned by walls 70h and 70i, respectively, and a first liquid storage portion 50a and a second liquid storage portion 50b are arranged.

They are arranged on one side (the side in the -X direction) of each other. On the other hand, the upstream passage portion 21b is arranged on the other side (the side in the X direction) with the two liquid storage portions 50 interposed therebetween in this cross-sectional view. In other words, the upstream passage portion 21a is arranged on the side of the first liquid storage portion 50a in the width direction of the suction tool 10, and the upstream passage portion 21b is arranged on the side of the second liquid storage portion 50b in the width direction of the suction tool 10. placed on the side.

The wick 30 is a member for introducing the liquid in the liquid storage section 50 to the load 40 in the load passage section 22 . The specific configuration of the wick 30 is not particularly limited as long as it has such a function. 50 liquids are introduced to the load 40; Hereinafter, when the bottom surface 52a of the first liquid storage portion 50a and the bottom surface 52b of the second liquid storage portion 50b are not distinguished from each other, they are referred to as the bottom surface 52 respectively. Liquid is movably connected between the liquid containing portion 50 and the wick 30 via the bottom surface 52 .

The load 40 is an electrical load for introducing the liquid in the liquid containing portion 50 and atomizing the introduced liquid to generate an aerosol. A specific configuration of the load 40 is not particularly limited, and for example, a heating element such as a heater or an element such as an ultrasonic generator can be used. In this embodiment, a heater is used as an example of the load 40 . As this heater, a heating resistor (that is, a heating wire), a ceramic heater, a dielectric heating type heater, or the like can be used. In this embodiment, a heating resistor is used as an example of this heater. Moreover, in this embodiment, the heater as the load 40 has a coil shape. That is, the load 40 according to this embodiment is a so-called coil heater. This coil heater is wound around a wick 30 .

Further, the load 40 according to the present embodiment is arranged in the wick 30 portion inside the load passage portion 22 as an example. The load 40 is electrically connected to the power supply and the control device of the power supply unit 11 described above, and heats up when electricity from the power supply is supplied to the load 40 (that is, heats up when energized). Also, the operation of the load 40 is controlled by a control device. The load 40 heats the liquid in the liquid containing portion 50 introduced into the load 40 through the wick 30 to atomize the liquid to generate an aerosol.

The configurations of the wick 30 and the load 40 are the same as the wick and the load used in a known suction tool as exemplified in Patent Document 2, for example, so further detailed description will be omitted.

The liquid containing portion 50 is a part for containing liquid for atomization. Hereinafter, this liquid is appropriately called an atomizing liquid Ld. The first liquid storage portion 50a is provided in a region surrounded by a wall portion 71a, a wall portion 71b, and a cylindrical wall portion 70h. The second liquid storage portion 50b is provided in a region surrounded by the wall portion 71a, the wall portion 71b, and the cylindrical wall portion 70i. Further, in the present embodiment, the downstream passage portion 23 described above is provided along the direction of the central axis CL between the first liquid storage portion 50a and the second liquid storage portion 50b.

The molded body 60 and the atomizing liquid Ld are accommodated in the first liquid accommodation portion 50a and the second liquid accommodation portion 50b, respectively. The first liquid storage portion 50a has a columnar shape consisting of an inner side surface 51a, a bottom surface 52a and an upper surface 53a. The second liquid storage portion 50b has a cylindrical shape consisting of an inner side surface 51b, a bottom surface 52b and an upper surface 53b. In the first liquid storage portion 50a, the atomizing liquid Ld is arranged on the bottom surface 52a side along the longitudinal direction, and the molded body 60 is arranged on the upper surface 53a side. Since the relative arrangement of the second liquid storage portion 50b, the atomizing liquid Ld, and the molded body 60 is the same as the arrangement in the first liquid storage portion 50a, description thereof will be omitted.

The atomizing liquid Ld contains at least one of natural nicotine and synthetic nicotine. That is, the nicotine contained in the liquid for atomization Ld may be natural nicotine alone, synthetic nicotine alone, or both natural nicotine and synthetic nicotine.

In addition, since natural nicotine is generally considered to be cheaper than synthetic nicotine, the manufacturing cost of the inhaler 10 is generally lower when natural nicotine is used than when synthetic nicotine is used. can be made cheaper. However, if for some reason it is not easy to obtain high-purity natural nicotine in the region where the suction device 10 is used, natural nicotine contained in the atomizing liquid Ld may be Synthetic nicotine is preferably used in conjunction with or in place of natural nicotine.

The atomizing liquid Ld can be a predetermined solvent containing at least one of natural nicotine and synthetic nicotine. Although the specific type of the predetermined solvent is not particularly limited, for example, one substance selected from the group consisting of glycerin, propylene glycol, triacetin, 1,3-butanediol, and water, Alternatively, a liquid containing two or more substances selected from this group can be used. Glycerin and propylene glycol can be used as examples of predetermined solvents.

When natural nicotine is used as the nicotine contained in the atomizing liquid Ld, natural nicotine extracted and refined from tobacco leaves can be used as the natural nicotine. For such a method for producing natural nicotine, for example, a well-known technique as exemplified in Non-Patent Document 1 can be applied, and detailed description thereof will be omitted.

Further, when natural nicotine is used as the nicotine contained in the liquid for atomization Ld, the tobacco leaf extract is purified to remove components other than natural nicotine from the tobacco leaf extract as much as possible, thereby reducing natural nicotine. Purified and natural nicotine with this enhanced purity may be used. To give a specific numerical example, the purity of the natural nicotine contained in the predetermined solvent of the liquid for atomization Ld may be 99.9 wt% or more (that is, in this case, the impurities contained in the natural nicotine ( ingredients other than natural nicotine) is less than 0.1 wt%).

On the other hand, when synthetic nicotine is used as the nicotine contained in the atomizing liquid Ld, nicotine produced by chemical synthesis using chemical substances can be used as the synthetic nicotine. The purity of this synthetic nicotine may also be 99.9 wt% or more, like natural nicotine.

The method for producing synthetic nicotine is not particularly limited, and known production methods can be used.

The ratio (% by weight (wt%)) of at least one of natural nicotine and synthetic nicotine contained in the atomizing liquid Ld is not particularly limited, but is, for example, 0.1 wt% or more and 7.5 wt% or less. A value selected from a range can be used.

The atomizing liquid Ld may contain flavor components other than natural nicotine and synthetic nicotine. Specific examples of flavor components of tobacco leaves include nicotine and neophytadiene.

FIG. 4 is a schematic perspective view of the molded body 60. FIG. 2, 3A, 3B, and 4, molded body 60 is formed by hardening tobacco leaves into a predetermined shape. Two molded bodies 60 according to the present embodiment are arranged inside each of the two liquid storage portions 50 . However, the number of molded bodies 60 and liquid storage portions 50 is not limited to this, and may be one or three or more. Also, a plurality of molded bodies 60 may be arranged in one liquid storage portion 50 .

The molded body 60 has a first surface S1, a second surface S2 facing the first surface S1, and a connection surface S3 connecting the first surface S1 and the second surface S2. In the example of the present embodiment, the molded body 60 has a cylindrical shape with the first surface S1 as the bottom surface and the connection surface S3 as the cylindrical surface.

The shapes of the liquid containing portion 50 and the molded body 60 are not particularly limited as long as at least part of the molded body 60 contacts the inner wall surface of the liquid containing portion 50 . The shape of the molded body 60 may be, for example, a bar shape extending in a predetermined direction (that is, a shape whose length is longer than its width), or a cubic shape (a shape having sides of the same length). Alternatively, it may be in the form of a sheet or in some other shape.

The shape of the molded body 60 according to the present embodiment is rod-like as an example. Specifically, the rod-shaped molded body 60 according to the present embodiment has, as an example, a rod-shaped polyhedron shape, and as an example, has a columnar shape with a circular cross section. Note that the cross-sectional shape of the molded body 60 is not limited to a circle, and other examples include polygons (triangles, quadrilaterals, pentagons, or polygons having 6 or more corners). may Further, when a sheet-shaped molded article 60 is used, specifically, a paper sheet of tobacco leaves, a cast sheet of tobacco leaves, a rolled sheet of tobacco leaves, or the like can be used as the molded article 60 .

From the viewpoint of efficiently accommodating the molded body 60 in the liquid storage portion 50, it is preferable that the molded body 60 is covered with a member that shrinks into a pre-stored shape. The molded body 60 is rod-shaped and is preferably covered with a heat-shrinkable tube.

In addition, specific values of the width (that is, the outer diameter) (W), which is the length in the lateral direction of the molded body 60, and the total length (L), which is the length in the longitudinal direction of the molded body 60, are particularly limited. An example of numerical values is as follows. That is, as the width (W) of the molded body 60, a value selected from a range of, for example, 2 mm or more and 20 mm or less can be used. As the total length (L) of the molded body 60, a value selected from the range of, for example, 5 mm or more and 50 mm or less can be used. However, these values are merely examples of the width (W) and the total length (L) of the molded body 60, and the width (W) and the total length (L) of the molded body 60 are suitable for the size of the suction tool 10. value should be set.

Further, in the present embodiment, the density (mass per unit volume) of the compact 60 is, for example, 1100 mg/cm ³ or more and 1450 mg/cm ³ or less. However, the density of the compact 60 is not limited to this, and may be less than 1100 mg/cm ³ or greater than 1450 mg/cm ³ .

The shape of the liquid containing portion 50 is preferably based on the shape of the molded body 60 . This makes it easier for the inner wall surface of the liquid containing portion 50 to come into contact with the compact 60 over a large area, and as a result, the area of the compact 60 that can come into contact with the atomizing liquid Ld can be reduced, and the tobacco leaves swell. can be suppressed.

When housing the molded body 60 in the liquid storage portion 50 , it is preferable that at least a portion of the connection surface S<b>3 of the molded body 60 contacts the inner wall surface of the liquid storage portion 50 . This makes it difficult for the atomizing liquid Ld to come into contact with at least one surface of the molded body 60 connected to the connection surface S3. More preferably, 25% or more of the area of the connecting surface S3 is substantially in contact with the inner wall surface of the liquid containing portion 50, and 50% or more is substantially in contact with the inner wall surface of the liquid containing portion 50 when the molded body 60 is accommodated in the liquid containing portion 50. It is more preferable that 75% or more of the connection surface S3 is substantially in contact, and it is even more preferable that the entire connection surface S3 is substantially in contact. A certain point on the connection surface S3 of the molded body 60 “substantially contacts” the inner wall surface of the liquid containing portion 50 means that the point on the molded body 60 is within 0.1 mm in the normal direction from the inner wall surface. means to exist. Therefore, it is more preferable that 25% or more of the area of the connecting surface S3 of the molded body 60 exists within 0.1 mm from the inner wall surface of the liquid containing portion 50, and more preferably 50% or more exists. % or more, and more preferably the entire connecting surface S3 is present. As the contact area of the connection surface S3 increases, the contact area of the liquid for atomization Ld and the formed body 60 can be reduced, and the swelling of the tobacco leaves can be suppressed. In the example of the present embodiment, the entire connecting surface S3 of the molded body 60 is in contact with the inner side surface (the inner side surface of the wall portion 70h) 51a of the first liquid storage portion 50a.

In this embodiment, the first surface S1 of the molded body 60 is in contact with or can be in contact with the atomizing liquid Ld, and the second surface S2 opposite to the first surface S1 is prevented from being in contact with the atomizing liquid Ld. Also, the molded body 60 is housed in the liquid housing portion 50 . As a result, the part of the compact 60 that the liquid for atomization Ld contacts is limited to a part of the surface (the first surface S1).

The method of housing the molded body 60 in the liquid containing portion 50 is not particularly limited as long as the contact between the molded body 60 and the liquid containing portion 50 can be maintained. The molded body 60 is preferably fixed to the liquid containing portion 50 . In the example of this embodiment, the molded body 60 is inserted into the first liquid storage portion 50a after being compressed in the width direction and the thickness direction. The inner surface 51a of the first liquid storage portion 50a is pressed by the restoring force from the compression of the compact 60 . The molded body 60 is fixed to the inner surface 51a by the frictional force based on this restoring force. Such a storage method does not require a member to be arranged inside the liquid storage section 50, and can efficiently store the compact 60. FIG. In addition, the atomization liquid Ld is less likely to flow along the inner side surface 51a of the liquid containing portion 50a, so that it can be suppressed from going around the inner side surface 51a toward the upper surface side, thereby suppressing the swelling of the tobacco leaves.

The suction using the suction tool 10 is performed as follows. First, when the user starts sucking air, the air passes through the upstream passage portions 21 a and 21 b of the air passage 20 and flows into the load passage portion 22 . Aerosol generated in the load 40 is added to the air that has flowed into the load passage portion 22 . This aerosol contains the flavor component eluted from the compact 60 placed in the atomizing liquid Ld, and at least one of natural nicotine and synthetic nicotine. The aerosol-added air passes through the downstream passage portion 23 and is discharged from the discharge port 13 to be sucked by the user.

According to the suction tool 10 according to the present embodiment as described above, the tobacco leaf flavor component contained in the molded body 60 can be added to the aerosol generated by the load 40 . This makes it possible to fully enjoy the flavor of tobacco leaves.

Further, according to the suction tool 10 according to the present embodiment, the molded tobacco leaf 60 is arranged in contact with the inner side surfaces 51a and 51b inside the first liquid storage portion 50a and the second liquid storage portion 50b, respectively. This reduces the contact area between the liquid containing portion 50 and the compact 60, thereby suppressing the swelling of the tobacco leaves. As a result, the compact 60 and the electrical load 40 of the suction tool 10 are physically separated, so that attachment of tobacco leaves to the load 40 of the suction tool 10 can be suppressed. As a result, deterioration of the load 40 of the suction tool 10 can be suppressed. Also, it is possible to suppress a decrease in the usable amount of the atomizing liquid Ld.

Also, the amount (mg) of the carbonized component contained in 1 g of the atomizing liquid in which the compact 60 is arranged is preferably 6 mg or less, more preferably 3 mg or less.

According to this configuration, it is possible to enjoy the flavor of tobacco leaves while suppressing the amount of carbonized components adhering to the electrical load 40 as much as possible. As a result, it is possible to enjoy the flavor of tobacco leaves while minimizing the occurrence of scorching of the load 40 .

It should be noted that "the carbonized component contained in the atomizing liquid in which the compact 60 is arranged" specifically refers to the carbonized component contained in the atomizing liquid before the compact 60 is arranged. and the amount of the carbonized component eluted into the atomizing liquid Ld from the compact 60 placed in the atomizing liquid Ld.

In addition, in the present embodiment, "carbonized component" refers to a component that becomes a carbide when heated to 250°C. Specifically, the term "carbonized component" refers to a component that does not form a carbide at a temperature of less than 250°C, but that forms a carbide when the temperature is maintained at 250°C for a predetermined period of time.

The "amount (mg) of the carbonized component contained in 1 g of the atomizing liquid in which the compact 60 is arranged" can be measured, for example, by the following method. First, a predetermined amount (g) of the atomizing liquid Ld in which the molded body 60 is arranged is prepared. Next, the atomizing liquid Ld is heated to 180° C. to volatilize the solvent (liquid component) contained in the atomizing liquid Ld, thereby obtaining a “residue composed of non-volatile components”. The residue is then heated to 250° C. to carbonize the residue to obtain a carbide. The amount (mg) of this carbide is then measured. By the above method, it is possible to measure the amount (mg) of chars contained in a predetermined amount (g) of the atomizing liquid, and based on this measured value, the amount of chars contained in 1 g of the atomizing liquid. (that is, the amount (mg) of the carbonized component) can be calculated.

Next, the relationship between the amount of carbonized components contained in 1 g of the atomizing liquid and the TPM reduction rate will be described. FIG. 5 is a diagram showing the results of measuring the TPM reduction rate with respect to the amount of carbonized component contained in 1 g of atomizing liquid. The horizontal axis of FIG. 5 indicates the amount of carbonized component contained in 1 g of the atomizing liquid, and the vertical axis indicates the TPM reduction rate (R _TPM ) (%).

The TPM reduction rate (R _TPM : %) in FIG. 5 was measured by the following method. First, a plurality of suction tool samples having different amounts of carbonized components contained in 1 g of the atomizing liquid were prepared. Specifically, five samples (sample SA1 to sample SA5) were prepared as samples of the plurality of suction tools. These five samples were prepared by the following steps.

(Step 1)
20 (wt%) of potassium carbonate in terms of dry weight was added to tobacco raw material composed of tobacco leaves, and then heat distillation treatment was performed. The distillation residue after the heat distillation treatment is immersed in water of 15 times the weight of the tobacco raw material before the heat distillation treatment for 10 minutes, dehydrated with a dehydrator, and then dried with a dryer to obtain tobacco. A residue was obtained.

(Step 2)
Next, a portion of the tobacco residue obtained in step 1 was washed with water to prepare a tobacco residue containing a small amount of charcoal.

(Step 3)
Next, 25 g of an immersion liquid (propylene glycol 47.5 wt%, glycerin 47.5 wt%, water 5 wt%) as an extract liquid was added to 5 g of the tobacco residue obtained in step 2, and the temperature of the immersion liquid was raised to 60. °C and allowed to stand. By varying the standing time (that is, the immersion time in the immersion liquid), the amount of carbonized component eluted into the immersion liquid (extract) was varied.

Through the above steps, a plurality of samples with different amounts of carbonized components contained in 1 g of the immersion liquid (extract) were prepared.

Next, automatic smoking was performed on the plurality of samples prepared in the above-described steps using an automatic smoking machine ("Analytical Vaping Machine" manufactured by Borgwaldt) under "CRM (Coresta Recommended Method) 81 smoking conditions". Ta. The CRM 81 smoking condition is a condition in which 55 cc of aerosol is inhaled over 3 seconds, and is performed multiple times every 30 seconds.

The amount of total particulate matter collected by the Cambridge filter of the automatic smoking machine was then measured. Based on the measured amount of total particulate matter, the TPM reduction rate (R _TPM ) was calculated using the following formula (1). The TPM reduction rate (R _TPM ) in FIG. 5 was measured by the above method.

R _TPM (%) = (1-TPM (201 puff to 250 puff) / TPM (1 puff to 50 puff)) x 100 (1)

Here, TPM (Total Particle Molecule) indicates the total particulate matter captured by the Cambridge filter of the automatic smoking machine. “TPM (1 puff to 50 puff)” in the formula (1) indicates the amount of total particulate matter collected by the Cambridge filter from the 1st puff to the 50th puff of the automatic smoking machine. "TPM (201 puff to 250 puff)" in equation (1) indicates the amount of total particulate matter captured by the Cambridge filter from the 201st puff to the 250th puff of the automatic smoking machine.

That is, the TPM reduction rate (R _TPM ) in Equation (1) is defined as "the amount of total particulate matter collected by the Cambridge filter from the 201st puff to the 250th puff of the automatic smoking machine. 1 minus the value obtained by dividing by the amount of total particulate matter collected by the Cambridge filter from the 1st puff to the 50th puff, and multiplied by 100.

As can be seen from FIG. 5, there is a proportional relationship between the amount of carbonized components contained in 1 g of the atomizing liquid and the TPM reduction rate. As can be seen particularly from samples SA1 to SA4 in FIG. 5, when the amount of carbonized component contained in 1 g of the atomizing liquid is 6 mg or less, the TPM reduction rate can be suppressed to 20% or less.

FIG. 6 is a flowchart for explaining the manufacturing method of the atomization unit for suction tools according to this embodiment.

In the extraction process of step S10, flavor components are extracted from tobacco leaves. Although the specific method of step S10 is not particularly limited, for example, the following method can be used. First, an alkaline substance is applied to tobacco leaves (referred to as alkaline treatment). As the alkaline substance used here, for example, a basic substance such as an aqueous solution of potassium carbonate can be used.

Next, the alkali-treated tobacco leaves are heated at a predetermined temperature (for example, a temperature of 80°C or more and less than 150°C) (referred to as heat treatment). Then, during this heat treatment, for example, one substance selected from the group consisting of glycerin, propylene glycol, triacetin, 1,3-butanediol, and water, or a substance selected from this group Two or more substances are brought into contact with tobacco leaves.

By this heat treatment, released components (flavor components are included here) released from tobacco leaves into the gas phase are collected in a predetermined collection solvent. As the collection solvent, for example, one substance selected from the group consisting of glycerin, propylene glycol, triacetin, 1,3-butanediol, and water, or two types selected from this group The above substances can be used. As a result, a collection solvent containing flavor components can be obtained (that is, flavor components can be extracted from tobacco leaves).

Alternatively, step S10 can be configured without using the collection solvent as described above. Specifically, in this case, after subjecting the alkali-treated tobacco leaves to the above-described heat treatment, the components released from the tobacco leaves into the gas phase are cooled using a condenser or the like. can be condensed to extract flavor components.

Alternatively, step S10 may be configured without the alkali treatment as described above. Specifically, in this case, in step S10, tobacco leaves (tobacco leaves that have not been subjected to alkali treatment) are treated with glycerin, propylene glycol, triacetin, 1,3-butanediol, and water. A selected substance or two or more substances selected from this group are added. Next, the tobacco leaves to which this has been added are heated, and the components released during this heating are collected in a collection solvent or condensed using a condenser or the like. Flavor components can also be extracted by such a process.

Alternatively, in step S10, an aerosol in which one substance selected from the group consisting of glycerin, propylene glycol, triacetin, 1,3-butanediol, and water is aerosolized, or an aerosol selected from this group Tobacco leaves (tobacco leaves that have not been subjected to alkali treatment) are passed through the aerosol in which two or more kinds of substances are aerosolized, and the aerosol that has passed through the tobacco leaves is collected by a collection solvent. Flavor components can also be extracted by such a process.

After step S10, the molding process of step S20 is executed. In step S20, the "tobacco residue", which is the tobacco leaves after being extracted in the extraction step of step S10, is hardened and molded into a predetermined shape (in this embodiment, a rod shape as an example), thereby forming the compact 60. to manufacture. A specific example of this step S20 is as follows.

For example, in step S20, after the tobacco residue is hardened into a predetermined shape to produce the molded body 60, the surface of the molded body 60 is coated with a coating material. As a result, the molded body 60 having a structure in which the surface of the tobacco residue hardened into a predetermined shape is covered with the coating material can be manufactured.

For example, wax can be used as this coating material. Examples of this wax include Microcrystalline WAX manufactured by Nippon Seiro Co., Ltd. (model number: Hi-Mic-1080 or model number: Hi-Mic-1090), and water-dispersed ionomer manufactured by Mitsui Chemicals (model number: Chemipearl S120). ), Mitsui Chemicals Hi-Wax (model number: 110P), or the like can be used.

Alternatively, corn protein can be used as the coating material. A specific example of this is Zein (model number: Kobayashi Zein DP-N) manufactured by Kobayashi Koryo Co., Ltd.

Alternatively, polyvinyl acetate can be used as the coating material.

The coating material covering the surface of the molded body 60 is provided with a plurality of holes (fine holes) through which the flavor component remaining in the tobacco residue can pass while suppressing passage of the tobacco residue. preferably. That is, the pores of the coating material may be larger than the size of the flavor component and smaller than the size of the tobacco residue. According to this configuration, the flavor component remaining in the tobacco residue can be eluted into the atomizing liquid Ld while suppressing the elution of the tobacco residue into the atomizing liquid Ld.

The specific size (diameter) of the holes provided in this coating material is not particularly limited, but to give a specific example, for example, a value selected from the range of 10 μm or more and 3 mm or less can be used. can.

A net-like mesh member can also be used as the coating material. In this case as well, the flavor component remaining in the tobacco residue can be eluted into the atomizing liquid Ld while suppressing the elution of the tobacco residue into the atomizing liquid Ld. Also, the molded body may be covered with a shape memory member such as a heat-shrinkable tube.

Further, in the molding process of step S20, the tobacco residue can be mixed with a resin to harden the tobacco residue to produce the molded body 60. In this case as well, the flavor component remaining in the tobacco residue can be eluted into the atomizing liquid Ld while suppressing the elution of the tobacco residue into the atomizing liquid Ld.

Alternatively, in the molding process of step S20, the tobacco residue may be washed with a cleaning liquid, and the molded product 60 may be manufactured by molding the washed tobacco residue by the method described above. According to this configuration, the amount of carbonized components contained in the tobacco residue is reduced as much as possible by washing, and the compact 60 can be manufactured using the tobacco residue with the reduced amount of carbonized components. As a result, it is possible to effectively suppress adhesion of carbonized components to the load 40 . As a result, scorching of the load 40 can be effectively suppressed.

After step S20, the accommodation process related to step S30 is executed. Specifically, in step S30, the atomization unit 12 in which the molded body 60 is not stored is prepared, and the molded body 60 after step S20 is placed in the liquid storage section 50 of the atomization unit 12. The molded body 60 is housed in the liquid housing portion 50 so that at least a portion of the molded body 60 is in contact with the wall surface of the liquid housing portion 50 . Next, at least one of natural nicotine and synthetic nicotine and one substance selected from the group consisting of glycerin, propylene glycol, triacetin, 1,3-butanediol, and water, or , and a solvent such as two or more substances selected from this group. In this case, a flavor component may be added to the atomizing liquid Ld contained in the liquid container 50 in addition to the flavor component added to the compact 60 in step S20. Further, a configuration may be adopted in which the user is provided with an atomizing unit for a suction device without storing the liquid to be atomized Ld, and the user stores the liquid to be atomized Ld in the liquid storage section 50 by himself or herself.

Through the above steps, the atomization unit 12 of the suction tool 10 according to this embodiment is manufactured. According to the manufacturing method according to the present embodiment, it is possible to manufacture the atomization unit 12 of the suction tool 10 in which swelling of tobacco leaves is suppressed while effectively using tobacco residue as a material for the molded body 60 . As a result, deterioration of the load 40 of the suction tool 10 can be suppressed, and reduction in usable atomization liquid can be suppressed.

As a result, the movement of the molded body is restricted by the spacer, so that it is possible to suppress the atomization liquid from entering surfaces other than the first surface of the molded body.

FIG. 7 is a cross-sectional view schematically showing the liquid containing portion 501 of this modified example. The liquid containing portion 501 includes an inner surface 51 , a bottom surface 52 connected to the wick 30 , and a top surface 53 .

A spacer 90 is arranged between the bottom surface 52 and the first surface S1 of the molded body 60 in the liquid containing portion 501 . The spacer 90 is arranged so that its first end contacts the bottom surface 52 and its second end contacts the molded body 60 to limit the movement of the molded body 60 toward the wick 30 side. Therefore, it is difficult for the atomizing liquid Ld to reach the second surface S2. The size or shape of the spacer 90 is not particularly limited as long as it can at least partially restrict the movement of the molded body 60, and it may or may not be fixed.

For example, membrane 62 can comprise at least one of cellulose acetate, aromatic polyamide, polyvinyl alcohol and polysulfone. Membrane 62 also preferably comprises a non-woven fabric. For example, the film 62 can be formed by bonding the material of the film 62 to the molded body 600 by thermal welding, or fixing the film 62 on the molded body 600 using a heat-shrinkable tube. In addition, the film 62 is preferably arranged on the first surface of the molded body at the portion facing the opening 91h in the fourth modification described above or the portion facing the opening 92s in the fifth modification described above.
