Detailed Description
(embodiment)
Hereinafter, a suction tool 10 according to an embodiment of the present invention will be described with reference to the drawings. In addition, the drawings of the present application are schematically illustrated for easy understanding of the features of the embodiments, and the dimensional ratios and the like of the respective constituent elements are not necessarily the same as those of the actual ones. In the drawings of the present application, orthogonal coordinates of X-Y-Z are illustrated as needed.
Fig. 1 is a perspective view schematically showing the external appearance of a suction tool 10 according to the present embodiment. The suction device 10 of the present embodiment is a suction device of a non-combustion heating type, specifically, an electronic cigarette of a non-combustion heating type.
The suction tool 10 of the present embodiment extends in the direction of the center axis CL of the suction tool 10 as an example. Specifically, the suction tool 10 has, as an example, an external shape having a "longitudinal direction (direction of the center axis CL)", a "width direction" orthogonal to the longitudinal direction, and a "thickness direction" orthogonal to the longitudinal direction and the width direction. The dimensions of the suction tool 10 in the longitudinal direction, the width direction, and the thickness direction become smaller in order. In the present embodiment, the direction of the Z axis (Z direction or-Z direction) in the orthogonal coordinates of X-Y-Z corresponds to the longitudinal direction, the direction of the X axis (X direction or-X direction) corresponds to the width direction, and the direction of the Y axis (Y direction or-Y direction) corresponds to the thickness direction.
The suction tool 10 has a power supply unit 11 and an atomizing unit 12. The power supply unit 11 is detachably connected to the atomizing unit 12. A battery, a control device, and the like as a power source are disposed inside the power source unit 11. When the atomizing unit 12 is connected to the power supply unit 11, the power supply of the power supply unit 11 is electrically connected to a load 40 described later of the atomizing unit 12.
The atomizing unit 12 is provided with an air outlet 13. Air containing aerosol is discharged from the discharge port 13. When the suction tool 10 is used, a user of the suction tool 10 can inhale air discharged from the discharge port 13.
A sensor that outputs a value of pressure change in the interior of the suction tool 10 generated by suction of the user through the discharge port 13 is arranged in the power supply unit 11. When the user starts sucking air, the sensor senses the start of sucking air and transmits the air to the control device, and the control device starts energization to a load 40 of the atomizing unit 12 described later. When the user finishes sucking air, the sensor senses the end of sucking air and transmits the air to the control device, which ends the energization to the load 40.
The power supply unit 11 may be provided with an operation switch for transmitting an air suction start request and an air suction end request to the control device by a user operation. In this case, the user can transmit the air suction start request and the air suction end request to the control device by operating the operation switch. Then, the control device that received the suction start request and suction end request starts and ends the energization to the load 40.
The configuration of the power supply unit 11 described above is the same as that of a known suction tool as exemplified in patent document 1, and therefore a further detailed description thereof is omitted.
Fig. 2 is a schematic cross-sectional view showing a main part of the atomizing unit 12 of the suction tool 10. Specifically, fig. 2 schematically illustrates a cross section of a main portion of the atomizing unit 12 cut in a plane including the center axis CL. Fig. 3 is a view schematically showing a section along line A1-A1 of fig. 2 (i.e., a section taken along a section normal to the center axis CL). The atomizing unit 12 will be described with reference to fig. 2 and 3.
The atomizing unit 12 of the present embodiment includes a plurality of wall portions (wall portions 70a to 70 g) extending in the longitudinal direction (the direction of the center axis CL), and a plurality of wall portions (wall portions 71a to 71 c) extending in the width direction. The atomizing unit 12 includes an air passage 20, a wick 30, an electric load 40, a liquid storage portion 50, and a filler 60.
The Air passage 20 is a passage for Air (Air) to pass through when the user sucks Air (i.e., sucks aerosol). The air passage 20 of the present embodiment includes an upstream passage portion, a load passage portion 22, and a downstream passage portion 23. The upstream passage portion of the present embodiment includes a plurality of upstream passage portions, specifically, an upstream passage portion 21a (i.e., a "first upstream passage portion") and an upstream passage portion 21b (i.e., a "second upstream passage portion").
The upstream passage portions 21a and 21b are disposed upstream of the load passage portion 22 (upstream in the air flow direction). Downstream end portions of the upstream passage portions 21a, 21b communicate with the load passage portion 22. The load path 22 is a path in which the load 40 is disposed. The downstream passage portion 23 is a passage portion disposed downstream (downstream in the air flow direction) of the load passage portion 22. The upstream end of the downstream passage portion 23 communicates with the load passage portion 22. The downstream end of the downstream passage portion 23 communicates with the discharge port 13. The air having passed through the downstream passage portion 23 is discharged from the discharge port 13.
Specifically, the upstream passage portion 21a of the present embodiment is provided in a region surrounded by the wall portions 70a, 70b, 70e, 70f, 71a, and 71 b. The upstream passage portion 21b is provided in a region surrounded by the wall portions 70c, 70d, 70e, 70f, 71a, and 71 b. The load path portion 22 is provided in a region surrounded by the wall portions 70a, 70d, 70e, 70f, 71b, and 71 c. The downstream passage portion 23 is provided in a region surrounded by the cylindrical wall portion 70 g.
The wall portion 71a is provided with a hole 72a and a hole 72b. The air flows into the upstream passage portion 21a from the hole 72a, and flows into the upstream passage portion 21b from the hole 72b. The wall portion 71b is provided with a hole 72c and a hole 72d. The air passing through the upstream passage portion 21a flows into the load passage portion 22 from the hole 72c, and the air passing through the upstream passage portion 21b flows into the load passage portion 22 from the hole 72d.
In the present embodiment, the flow direction of the air in the upstream passage portions 21a, 21b is the opposite direction to the flow direction of the air in the downstream passage portion 23. Specifically, in the present embodiment, the flow direction of the air in the upstream passage portions 21a and 21b is the-Z direction, and the flow direction of the air in the downstream passage portion 23 is the Z direction.
Referring to fig. 2 and 3, the upstream passage portion 21a and the upstream passage portion 21b of the present embodiment are disposed adjacent to the liquid storage portion 50 so as to sandwich the liquid storage portion 50 between the upstream passage portion 21a and the upstream passage portion 21 b.
Specifically, as shown in fig. 3, the upstream passage portion 21a of the present embodiment is disposed on one side (-X direction side) via the liquid containing portion 50 when the cross section is taken by a cross section taken along the center axis CL as a normal line. On the other hand, in this cross-section, the upstream passage portion 21b is disposed on the other side (on the side in the X direction) with the liquid storage portion 50 interposed therebetween. In other words, the upstream passage portion 21a is disposed on one side of the liquid containing portion 50 in the width direction of the suction tool 10, and the upstream passage portion 21b is disposed on the other side of the liquid containing portion 50 in the width direction of the suction tool 10.
The cross-sectional shapes of the upstream passage portion 21a and the upstream passage portion 21b are not limited to the polygonal shape illustrated in fig. 3 (a quadrangle is an example in fig. 3), and may be other shapes (e.g., a circle or the like).
The wick 30 is a member for introducing the extracting solution of the liquid storage portion 50 into the load 40 of the load path portion 22. The specific structure of the wick 30 is not particularly limited as long as it has such a function, but the wick 30 of the present embodiment introduces the extraction liquid of the liquid storage portion 50 into the load 40 by capillary phenomenon as an example.
The load 40 is an electric load for generating aerosol by atomizing the introduced extracting solution introduced into the liquid storage portion 50. The 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 the present embodiment, a heater is used as an example of the load 40. As the heater, a heating resistor (i.e., heating wire), a ceramic heater, an induction heating type heater, or the like can be used. In the present embodiment, a heat generating resistor is used as an example of the heater, and a heat generating resistor having a coil shape is used as an example of the heat generating resistor. That is, the load 40 of the present embodiment is a so-called coil heater. The coil heater is wound around the die 30.
The load 40 of the present embodiment is disposed in the die 30 in the load path 22 as an example. The load 40 is electrically connected to the power supply and the control device of the power supply unit 11, and generates heat by supplying power from the power supply to the load 40 (i.e., generates heat when energized). The operation of the load 40 is controlled by the control device. The aerosol is generated by the load 40 by heating and atomizing the extraction liquid introduced into the liquid storage portion 50 of the load 40 via the wick 30.
The die 30 and the load 40 have the same structure as the die and the load used in the known suction tool as exemplified in patent document 1, and therefore, a further detailed description thereof is omitted.
The liquid storage portion 50 is a portion for storing an extraction liquid (Le) of tobacco leaves. The liquid storage portion 50 of the present embodiment is provided in a region surrounded by the wall portions 70b, 70c, 70e, 70f, 71a, and 71 b. In the present embodiment, the downstream passage portion 23 is provided as an example to penetrate the liquid storage portion 50 in the direction of the center axis CL. However, the configuration is not limited to this, and for example, the downstream passage portion 23 may be provided adjacent to the liquid containing portion 50 in the thickness direction (Y-axis direction) of the suction tool 10.
In the present embodiment, as the tobacco leaf extract, a substance containing a flavor component of tobacco leaf in a predetermined solvent is used. The specific type of the predetermined solvent is not particularly limited, but a liquid containing, for example, one selected from the group consisting of glycerin, propylene glycol, triacetin, 1, 3-butanediol, and water, or two or more selected from the group can be used. In the present embodiment, glycerin and propylene glycol are used as an example of a predetermined solvent.
Further, if specific examples of the flavor component of tobacco leaf are given, nicotine is given.
The filler 60 is a filler of tobacco leaves. Specifically, the filler 60 of the present embodiment is made of tobacco leaves filled in a part of the air passage 20. The filler 60 of the present embodiment fills the upstream passage portion 21a and the upstream passage portion 21b, respectively.
The filling rate (filling rate defined by the volume ratio) of the filler 60 at the portion (in the present embodiment, the upstream passage portion 21a and the upstream passage portion 21 b) of the air passage 20 where the filler 60 is disposed is not particularly limited, but is 60% or more as an example in the present embodiment. That is, the filling ratio of the filler 60 filled in the upstream passage portion 21a and the filling ratio of the filler 60 filled in the upstream passage portion 21b in the present embodiment are respectively 60% to 100%. However, this value is merely an example, and the filling rate of the filler 60 is not limited thereto. The filling rate of the filler 60 in the upstream passage portion 21a and the filling rate of the filler 60 in the upstream passage portion 21b need not be the same value, but may be different values from each other.
The tobacco leaves constituting the filler 60 may be "cut tobacco (cut tobacco) of tobacco leaves," granular particles "of tobacco leaves, or" shaped bodies "in which cut tobacco, granular particles, or granular particles are solidified and shaped into a predetermined shape. The particles of tobacco leaf mean a substance obtained by pulverizing tobacco leaf into powder. The particles of tobacco leaf means particles having a size larger than the particles by solidifying a plurality of particles.
In the present embodiment, as an example of the filler 60, a "molded body" formed into a predetermined shape by solidifying tobacco shreds of tobacco leaves is used, and the surface of the "molded body" is coated with a coating material such as wax. Such filler 60 fills the upstream passage portion 21a and the upstream passage portion 21b, respectively. In addition, the coating material may not be used for coating. However, it is preferable to coat the surface of the molded body with a coating material in order to easily maintain the shape of the molded body.
The shape of the molded body of the filler 60 is not particularly limited, and may be, for example, a rod shape (a shape having a longer length than a width), a cube shape (a shape having sides of the same length), or other shapes. The shape of the packing 60 of the present embodiment is a rod-like shape, specifically a rod-like polyhedron, as an example.
In this way, by using the molded body as the filler 60, the filler 60 can be transported alone more easily than in the case where the filler 60 is constituted by simply incorporating tobacco into the upstream passage portions 21a, 21 b. This facilitates the handling of the packing 60.
In the present embodiment, the density (mass per unit volume) of the filler 60 is 1100mg/cm as an example 3 1450mg/cm above 3 The following is given. However, the density of the filler 60 is not limited thereto, and may be less than 1100mg/cm 3 Or can be greater than 1450mg/cm 3 。
The suction using the suction tool 10 is performed as follows. First, when the user starts sucking air, air flows into the load path portion 22 through the upstream path portions 21a and 21b of the air path 20. The air flowing into the load passage portion 22 contains the flavor component of the tobacco leaf contained in the filler 60. The aerosol generated in the load 40 is added to the air flowing into the load passage 22. The aerosol contains tobacco leaf aroma components contained in the extract. The air to which the aerosol is added is discharged from the discharge port 13 through the downstream passage portion 23, and is sucked by the user.
According to the suction device 10 of the present embodiment described above, the tobacco leaf extract is stored in the liquid storage portion 50, and the filler 60 is disposed in the air passage 20, so that the flavor component of the tobacco leaf contained in the extract and the flavor component of the tobacco leaf contained in the filler 60 can be added to the air passing through the air passage 20. Thus, the flavor of tobacco leaves can be sufficiently tasted.
Further, according to the present embodiment, a flavor which cannot be fully expressed by only the flavor components of the tobacco leaves contained in the extracting solution or only the flavor components of the tobacco leaves contained in the filler 60 may be designed.
Next, a method of manufacturing the suction tool 10 will be described. Fig. 4 is a flowchart for explaining the manufacturing method of the present embodiment.
First, the extraction process of step S10 is performed. In this step S10, a flavor component is extracted from tobacco leaves. The specific method of step S10 is not particularly limited, but for example, the following method can be used. First, tobacco leaves are given an alkaline substance (called alkaline treatment). As the alkaline substance used herein, for example, an alkaline substance such as an aqueous potassium carbonate solution can be used.
Subsequently, the tobacco leaves subjected to the alkali treatment are heated at a predetermined temperature (for example, a temperature of 80 ℃ or higher and less than 150 ℃) (referred to as heat treatment). In the heat treatment, for example, tobacco leaves are contacted with one selected from the group consisting of glycerin, propylene glycol, triacetin, 1, 3-butanediol, and water, or two or more selected from the group.
By this heat treatment, the released component (including the flavor component here) released from the tobacco leaves into the gas phase is trapped by a predetermined trapping solvent. As the capturing solvent, for example, one selected from the group consisting of glycerin, propylene glycol, triacetin, 1, 3-butanediol, and water, or two or more selected from the group can be used. Thereby, a capturing solvent containing a flavor component (i.e., flavor component can be extracted from tobacco leaves) can be obtained.
Alternatively, the step S10 may be configured so as not to use the above-described trapping solvent. Specifically, in this case, after the tobacco leaves subjected to the alkali treatment are subjected to the above-described heat treatment, the tobacco leaves may be cooled by using a condenser or the like, so that the released components released from the tobacco leaves into the gas phase are condensed to extract the flavor components.
Alternatively, step S10 may be configured not to perform the alkali treatment as described above. Specifically, in this case, in step S10, one selected from the group consisting of glycerin, propylene glycol, triacetin, 1, 3-butanediol, and water, or two or more selected from the group are added to tobacco (tobacco not subjected to alkali treatment). Then, the tobacco leaves to which the above-described composition is added are heated, and the components released during the heating are trapped in a trapping solvent, or condensed by using a condenser or the like. By this step, the flavor component can be extracted.
Alternatively, in step S10, an aerosol obtained by aerosolizing one selected from the group consisting of glycerin, propylene glycol, triacetin, 1, 3-butanediol, and water, or an aerosol obtained by aerosolizing two or more selected from the group is passed through tobacco (tobacco not subjected to alkali treatment), and the aerosol passed through the tobacco is captured by a capturing solvent. By this step, the flavor component can be extracted.
In addition, step S10 of the present embodiment may further include reducing the amount of "carbonized component which becomes carbide when heated to 250 ℃. According to this configuration, the amount of the carbonized component adhering to the load 40 can be reduced, and thus the occurrence of scorching on the load 40 can be effectively suppressed.
The specific method for reducing the amount of the carbonized component contained in the extracted flavor component is not particularly limited, but for example, the component precipitated by cooling the extracted flavor component may be filtered with a filter paper or the like, thereby reducing the amount of the carbonized component contained in the extracted flavor component. Alternatively, the extracted flavor component may be centrifuged by a centrifugal separator to reduce the amount of carbonized component contained in the extracted flavor component. Alternatively, the amount of carbonized component contained in the extracted flavor component may be reduced by using a reverse osmosis membrane (RO filter).
After step S10, the processing step of step S20 and the concentration step of step S30 described below are performed.
In step S20, the "tobacco residue" which is the tobacco leaf extracted in the extraction step of step S10 is processed into cut tobacco, powder particles, or granules, thereby producing a "processed product". Alternatively, these processed products are solidified and formed into a predetermined shape to produce a "formed body". In the present embodiment, in step S20, tobacco leaves extracted in the extraction step of step S10 are processed into tobacco shreds (i.e., processed products), and then the tobacco shreds are solidified and formed into a predetermined shape (in the present embodiment, a rod shape is an example), thereby producing a molded article. The specific example of this step S20 is as follows.
For example, in step S20, a molded body is produced by solidifying cut tobacco to form a predetermined shape, and then the surface of the molded body is coated with a coating material. In addition, as the coating material, for example, wax can be used.
In this case, it is preferable that the coating material covering the surface of the molded body is provided with a plurality of holes (fine holes) through which the flavor components remaining in the tobacco shreds can pass while suppressing the passage of the tobacco shreds. That is, the pores of the coating material may be pores having a size larger than the size of the flavor component and smaller than the size of the tobacco shred. According to this configuration, the flavor components remaining in the tobacco shreds can be moved to the extraction liquid while suppressing the tobacco shreds from moving to the extraction liquid.
The specific size (diameter) of the pores provided in the coating material is not particularly limited, but a value selected from a range of 10 μm to 3mm can be used, for example, if specific examples are given.
Further, as the coating material, a mesh-shaped mesh member may be used instead of wax. In this case, the flavor components remaining in the tobacco shreds can be moved to the extraction liquid while suppressing the tobacco shreds from moving to the extraction liquid.
In the processing step of step S20, the processed product (tobacco shred, powder particle, or granule) may be mixed with a resin to produce a molded article.
Alternatively, in the processing step of step S20, the tobacco residue may be washed with a washing liquid, and the washed tobacco residue may be processed by the above-described method to produce a processed product. According to this configuration, the amount of the carbonized component can be reduced as much as possible by cleaning, and the molded article can be produced using the processed product in which the amount of the carbonized component is reduced. This effectively suppresses the occurrence of scorching on the load 40.
On the other hand, in the concentration step of step S30, the flavor component extracted in step S10 is concentrated. Specifically, in step S30 of the present embodiment, the flavor component contained in the capturing solvent containing the flavor component extracted in step S10 is concentrated.
After step S30, the extract liquid manufacturing process of step S40 is performed. In step S40, the flavor component extracted in step S10 (specifically, in the present embodiment, the flavor component after concentration in step S30) is added to a predetermined solvent, thereby producing an extract of tobacco leaves. The specific type of the predetermined solvent is not particularly limited, but for example, one selected from the group consisting of glycerin, propylene glycol, triacetin, 1, 3-butanediol, and water, or two or more selected from the group can be used.
After step S40, the assembly process of step S50 is performed. Specifically, in step S50, the atomizing unit 12 is prepared in a state in which the extracting solution and the filler 60 are not stored, the "extracting solution for tobacco leaves" produced in step S40 is stored in the liquid storage portion 50 of the atomizing unit 12, and the air passage 20 is filled with the processed product or the molded product (the filled material corresponds to the filler 60) produced in the processing step of step S20. The suction tool 10 (specifically, the atomizing unit 12 of the suction tool 10) is manufactured through the above steps.
According to the manufacturing method of the present embodiment described above, the suction tool 10 can be manufactured while effectively using tobacco residue as the material of the filler 60.
In addition, the present embodiment may adopt a configuration not including step S30. In this case, in step S40, the flavor component extracted in step S10 may be added to a predetermined solvent to produce an extract of tobacco leaves. However, the case of including step S30 is preferable in that the amount of the flavor component contained in the tobacco leaf extract is larger than the case of not including step S30.
The amount (mg) of the carbonized component contained in 1g of the extract of the tobacco leaves produced in step S40 is preferably 6mg or less, more preferably 3mg or less.
According to this configuration, the flavor of tobacco leaves can be tasted while suppressing the amount of carbonized components adhering to the electric load 40 as much as possible. This makes it possible to taste the flavor of tobacco leaves while suppressing the occurrence of scorching of the load 40 as much as possible.
In the present embodiment, the "carbonized component" contained in 1g of the extract liquid means "a component that becomes a carbide when heated to 250 ℃. Specifically, the "carbonized component" refers to a component that does not become a carbide at a temperature of less than 250 ℃, but becomes a carbide when maintained at a temperature of 250 ℃ for a predetermined time.
The "amount (mg) of the carbonized component contained in 1g of the extract" can be measured, for example, by the following method. First, an extract of tobacco leaves of a predetermined amount (g) is prepared. Subsequently, the extract was heated to 180 ℃, and the solvent (liquid component) contained in the extract was volatilized, thereby obtaining "residue composed of nonvolatile components". Next, the residue was carbonized by heating the residue to 250 ℃ to obtain carbide. Next, the amount (mg) of the carbide was measured. By the above method, the amount (mg) of carbide contained in the tobacco leaf extract of a predetermined amount (g) can be measured, and based on the measured value, the amount (i.e., the amount (mg) of carbide component) contained in 1g of the tobacco leaf extract can be calculated.
Next, a relationship between the amount of the carbonized component contained in 1g of the tobacco leaf extract and the TPM reduction ratio will be described. Fig. 10 is a graph showing the results of measuring the TPM reduction rate with respect to the amount of carbonized components contained in 1g of the tobacco leaf extract. In FIG. 10, the horizontal axis represents the amount of carbonized components contained in 1g of the tobacco leaf extract, and the vertical axis represents the TPM reduction rate (R TPM )(％)。
TPM reduction rate (R) of FIG. 10 TPM : % by the following method. First, samples of a plurality of suction devices having different amounts of carbonized components contained in 1g of an extract liquid of tobacco leaves were prepared. Specifically, five samples (samples SA1 to SA 5) were prepared as samples of the plurality of suction devices. These five samples were prepared by the following procedure.
(Process 1)
To a tobacco raw material composed of tobacco leaves, 20 (wt%) of potassium carbonate by dry weight was added, followed by heat distillation treatment. The distillation residue after the heat distillation treatment was immersed in 15 times the weight of water relative to the tobacco material before the heat distillation treatment for 10 minutes, and then dehydrated by a dehydrator, and then dried by a dryer, thereby obtaining a tobacco residue.
(Process 2)
Next, a part of the tobacco residue obtained in step 1 is washed with water, and a tobacco residue containing a small amount of carbide is prepared.
(step 3)
Next, 25g of an impregnating liquid (propylene glycol 47.5wt%, glycerin 47.5wt%, water 5 wt%) was added to 5g of the tobacco residue obtained in step 2 as an extracting solution, and the impregnating liquid was allowed to stand at 60 ℃. By making the standing time (i.e., the immersion time in the immersion liquid) different, the amount of the carbonized component eluted into the immersion liquid (extract liquid) is made different.
Through the above steps, a plurality of samples having different amounts of carbonized components contained in 1g of the impregnating liquid (extract) were prepared.
Next, for the plurality of samples prepared in the above-described steps, automatic smoking was performed using an automatic smoking machine (Analytical Vaping Machine manufactured by Borgwaldt corporation) under the smoking condition of CRM (Coresta Recommended Method) 81. In addition, the smoking condition of CRM81 means a condition in which 55cc of aerosol is sucked every 30 seconds for 3 seconds.
Next, the amount of all particulate matters trapped in the cambridge filter included in the automatic smoking machine was measured. Based on the measured amount of all particulate matters, the TPM reduction rate (R) was calculated using the following formula (1) TPM ). The TPM reduction rate (R) of fig. 10 was measured by the above method TPM )。
R TPM (％)＝(1－TPM(201puff～250puff)/TPM(1puff～50puff))×100
···(1)
Here TPM (Total Particle Molecule) represents all particulate matter trapped by the cambridge filter of an automatic smoking machine. "TPM (1-50 puffs)" in the formula (1) represents the amount of all particulate matters trapped by the Cambridge filter between the first suction and the 50 th suction of the automatic smoking machine. "TPM (201-250 puff)" in expression (1) represents the amount of all particulate matter trapped by the cambridge filter between the 201 st puff and the 250 th puff of the automatic smoking machine.
Namely, the TPM reduction rate (R) of formula (1 TPM ) Calculated by subtracting a value obtained by dividing a value obtained by "the amount of all particulate matters trapped by the Cambridge filter between the 201 st suction and the 250 th suction of the automatic smoking machine by the amount of all particulate matters trapped by the Cambridge filter between the first suction and the 50 th suction of the automatic smoking machine" by 1 and multiplying the value by 100.
As can be seen from fig. 10, the amount of the carbonized component contained in 1g of the tobacco leaf extract has a proportional relationship with the TPM reduction rate. Further, as is clear from fig. 10, in particular, samples SA1 to SA4, when the amount of the carbonized component contained in 1g of the tobacco leaf extract is 6mg or less, the TPM reduction rate can be suppressed to 20% or less.
Next, a modification of the embodiment will be described. In the following modification, the same or corresponding components as those of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted as appropriate.
Modification 1
Fig. 5 is a schematic cross-sectional view showing a main part of the atomizing unit 12 of the suction tool 10A according to modification 1 of the embodiment. The suction tool 10A according to the present modification differs from the suction tool 10 of fig. 2 described above mainly in that tobacco particles are used as the filler 60A instead of tobacco.
In addition, upstream end portions of the upstream passage portions 21a and 21b are disposed in the upstream passage portion 21a and the upstream passage portion 21b, respectively, of the suction tool 10A of the present modification, and the filter 25a is disposed in the downstream end portions of the upstream passage portions 21a and 21 b. The region between the filters 25a and 25b is filled with a filler 60A composed of particles of tobacco leaves.
The filters 25a and 25b are made of porous members that allow air to pass therethrough and suppress the passage of particles of tobacco leaves. Specifically, the filters 25a and 25b are constituted by members having a plurality of holes having a size smaller than the size of the particles of tobacco leaves. By the filters 25a and 25b, the particles constituting the filler 60A are effectively prevented from leaking out of the holes 72a, 72b, 72c, and 72d to the outside of the upstream passage portions 21a and 21 b.
In this modification, the same operational effects as those of the suction tool 10 of the aforementioned embodiment can be achieved.
In the present modification, as the filler 60A, a filler filled with particles of tobacco leaves may be used.
Modification 2
Fig. 6 is a schematic cross-sectional view showing a main part of the atomizing unit 12 of the suction tool 10B according to modification 2 of the embodiment. Specifically, fig. 6 schematically illustrates a cross-sectional view in the thickness direction of the main portion of the atomizing unit 12 of the present modification. The air passage 20B of the suction tool 10B of the present modification is different from the air passage 20 of the suction tool 10 described above mainly in that only one upstream passage portion (only the upstream passage portion 21 a) is provided and in that the upstream passage portion 21a is disposed adjacent to the liquid storage portion 50 in the thickness direction of the suction tool 10B.
In this modification, the same operational effects as those of the suction tool 10 of the aforementioned embodiment can be achieved.
In this modification, the filler 60A of modification 1 may be used instead of the filler 60.
Modification 3
Fig. 7 is a schematic cross-sectional view showing a main part of the atomizing unit 12 of the suction tool 10C according to modification 3 of the embodiment. The suction tool 10C according to the present modification is different from the suction tool 10 described above mainly in that the air passage 20C does not have an upstream passage portion, and in that the filler 60 fills the downstream passage portion 23.
In the present modification, a hole 72e through which air flows is provided in the wall portion 71c of the load path portion 22. The air flows into the load passage portion 22 from the hole 72e, passes through the downstream passage portion 23 after passing through the load passage portion 22, and is discharged from the discharge port 13.
The downstream passage portion 23 of the present modification has an enlarged diameter portion 24a. The enlarged diameter portion 24a is a portion provided in a part of the downstream passage portion 23 and enlarged in diameter from the "other portion 24b (i.e., non-enlarged diameter portion)" of the downstream passage portion 23. Specifically, the entire downstream passage portion 23 of the present modification is disposed inside the liquid housing portion 50. The enlarged diameter portion 24a of the present modification is disposed at a portion of the downstream passage portion 23 in the middle of the passage. Specifically, the other portion 24b is disposed upstream of the expanded diameter portion 24a, and the other portion 24b is also disposed downstream of the expanded diameter portion 24a (that is, the expanded diameter portion 24a is sandwiched by the other portions 24 b). The filler 60 according to the modification is filled in the enlarged diameter portion 24a.
In this modification, the same operational effects as those of the suction tool 10 of the aforementioned embodiment can be achieved. Specifically, in the present modification, the flavor component of tobacco leaves contained in the extracting solution and the flavor component of tobacco leaves contained in the filler 60 can be added to the air passing through the air passage 20C, so that the flavor of tobacco leaves can be sufficiently tasted.
Further, according to the present modification, since the filler 60 is filled in the enlarged diameter portion 24a, the ventilation resistance value of the air passing through the filler 60 (an index indicating that the air is difficult to pass when the air passes) can be suppressed to be lower than that in the case where the filler 60 is filled in the other portion 24b, for example.
Further, according to the present modification, since the air whose temperature has risen by the load 40 passes through the filler 60, for example, compared with the case where the filler 60 is filled in the upstream passage portions 21a, 21b, the flavor component of the tobacco leaf contained in the filler 60 can be effectively added to the air in the downstream passage portion 23 (that is, the flavor component can be effectively attached to the air). In this case, the flavor of the tobacco leaves can be sufficiently tasted. Further, according to the present modification, the filler 60 is disposed only in the downstream passage portion 23, and therefore the filler 60 can be easily attached to and detached from the suction tool 10C.
As described above, the downstream passage portion 23 according to the present modification is disposed entirely inside the liquid storage portion 50, but the present invention is not limited to this configuration. The downstream passage portion 23 may be disposed adjacent to the liquid containing portion 50 in the thickness direction of the suction tool 10C.
Modification 4
Fig. 8 is a schematic cross-sectional view showing a main part of the atomizing unit 12 of the suction tool 10D according to modification 4 of the embodiment. The suction tool 10D according to the present modification differs from the suction tool 10C according to modification 3 mainly in that a filler 60A filled with tobacco particles is used instead of the filler 60.
In the present modification, a filter 25a is disposed at an upstream end of the expanded diameter portion 24a, and a filter 25b is disposed at a downstream end of the expanded diameter portion 24a. A filler 60A is filled in a region between the filters 25a and 25b, and the filler 60A is filled with particles of tobacco leaves. The filters 25a and 25b are the same as those described in the modification 1 (fig. 5), and therefore, detailed description thereof is omitted.
In this modification, the same operational effects as those of the suction tool 10C of modification 3 described above can be obtained.
In the present modification, as the filler 60A, a filler filled with particles of tobacco leaves may be used.
Modification 5
Fig. 9 is a schematic cross-sectional view showing a main part of the atomizing unit 12 of the suction tool 10E according to modification 5 of the embodiment. The suction tool 10E according to the present modification differs from the suction tool 10C according to modification 3 in that the "other portion 24b" of the downstream passage portion 23 is mainly provided so as to penetrate the inside of the liquid storage portion 50, and the enlarged diameter portion 24a is disposed downstream of the "other portion 24b" in the air flow direction. That is, the downstream passage portion 23 of the present modification has another portion 24b on the upstream side, and has an enlarged diameter portion 24a on the downstream side of the other portion 24 b. The enlarged diameter portion 24a of the present modification also functions as a downstream extension portion extending downstream of the liquid containing portion 50 in the air flow direction.
The enlarged diameter portion 24a of the present modification has an enlarged diameter having a width and a thickness equal to the width and the thickness of the liquid storage portion 50. However, the shape of the expanded diameter portion 24a is not limited thereto.
In this modification, the same operational effects as those of the suction tool 10C of modification 3 described above can be obtained.
Further, according to the present modification, since the enlarged diameter portion 24a is not disposed inside the liquid storage portion 50 (or is not adjacent to the liquid storage portion 50 in the thickness direction of the suction tool 10E), the cross-sectional area of the enlarged diameter portion 24a, the length in the air flow direction (length in the Z direction) in the enlarged diameter portion 24a, and the like can be easily adjusted. This makes it possible to easily adjust the ventilation resistance value of the air passing through the filler 60 to a desired value.
In this modification, the air passing through the expanded diameter portion 24a may also flow so as to spread in the radial direction of the expanded diameter portion 24a as illustrated in fig. 9. Specifically, in this case, as illustrated in the partial enlarged view of fig. 9, the inner peripheral wall surface of the enlarged diameter portion 24a extending in the Z-axis direction may be provided with "at least one groove 24c (a plurality of grooves 24c are illustrated in fig. 9)" extending in the circumferential direction of the enlarged diameter portion 24 a. As shown in the partial enlarged view of fig. 9 (a perspective view shown by "A1"), the inner peripheral wall surface of the enlarged diameter portion 24a extending in the X-axis direction (inner peripheral wall surface in the X-Y plane) may be provided with "at least one groove 24c (a plurality of grooves 24c are illustrated in fig. 9) extending in the X-axis direction. According to this configuration, the air can be effectively diffused in the radial direction of the enlarged diameter portion 24 a.
In this modification, the filler 60A of modification 4 described above may be used instead of the filler 60. In this case, the filters 25a and 25b may be further disposed in the enlarged diameter portion 24a.
The other portion 24b of the downstream passage portion 23 is not limited to the structure penetrating the inside of the liquid storage portion 50 as illustrated in fig. 9. As another example, the other portion 24b may be adjacent to the liquid storage portion 50 in the thickness direction of the suction tool 10E.
The groove 24c provided in the enlarged diameter portion 24a of the present modification may be provided in the enlarged diameter portion 24a of the suction tool of the above-described modification 3 (fig. 7) or modification 4 (fig. 8).
The embodiments and modifications of the present invention have been described in detail above, but the present invention is not limited to the specific embodiments and modifications, and various modifications and alterations can be made within the scope of the gist of the present invention described in the claims.
