20250064106
The present application claims priority to Korean Patent Application No. 10-2023-0109855, filed on Aug. 22, 2023, the entire contents of which is incorporated herein for all purposes by this reference.
The present disclosure relates to a smoking article usable in both heated and combustible types, more specifically a smoking article and an aerosol-generating system including the same.
Consumers in the tobacco market can be categorized depending on their preference as follows: those who prefer heated tobacco, those who prefer combustible tobacco, or those who carry both types of tobacco for interchangeable use based on preference, place, or time.
Combustible tobacco enables aerosol generated from a medium combusted by a heat source to transition to a consumer when inhaled, without a device. Heated tobacco enables aerosol resulting from a medium heated by a heating source of a device to transition to a consumer when inhaled. These two smoking types significantly differ from each other in the temperature of each medium during smoking. To allow tobacco ingredients to transition well to consumers at each temperature, cigarettes or sticks are designed.
Typically, when heating a combustible smoking article to a temperature of 400° C. or lower for inhalation, there are problems in that aerosol is hardly generated, and the transition of a medium component is constrained. In addition, when combusting a heated smoking article for inhalation, there are problems in that combustion fails to occur smoothly, and ignition either fails to occur or lasts shortly. For this reason, consumers who interchangeably use heated tobacco and combustible tobacco have to deal with the inconvenience of carrying both types of tobacco.
The present disclosure, which has been proposed to solve the problems, aims to provide a smoking article usable in both heated and combustible types.
In addition, the present disclosure aims to provide an aerosol-generating system including the smoking article.
Objectives of the present disclosure are not limited to the objectives mentioned above. Other objectives and advantages of the present disclosure not mentioned will be clearly understood from the description and embodiments of the present disclosure below.

In addition to the effects described above, specific effects of the present disclosure will be described below with reference to specific details for carrying out the present disclosure.
As used herein, unless the context clearly indicates otherwise, the singular forms are intended to include the plural forms.
As used herein, “configured to” may be used interchangeably with, for example, “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, or “capable of”, depending on some embodiments. The term “configured to (or set to)” may not necessarily mean “specifically designed to” in terms of hardware. Instead, in some embodiments, the expression “device configured to” may mean that the device is “capable of” being in combination with other devices or components.
As used herein, “at least one of a, b, and c” may include a, b, or c alone or a combination of two or more selected from the group consisting of a, b, and c.
As used herein, the term “connected” not only means that certain members are directly connected but also means that members are indirectly connected by interposing other members therebetween.
As used herein, the term “to” refers to a numerical range including the respective values listed before and after this term as lower and upper limits. When a plurality of numerical values is disclosed for the upper and lower limits of a numerical range, the numerical range disclosed herein may be understood as a numerical range including any one value of the plurality of lower limit values and any one value of the plurality of upper limit values as the lower limit value and the upper limit value, respectively. For example, assuming that “a to b” or “c to d” is stated herein, this may be understood as follows: a or more and b or less, a or more and d or less, c or more and d or less, or c or more and b or less.
As used herein, the term “upstream” or “upstream direction” may refer to a direction moving away from the mouth end of a smoker, and the term “downstream” or “downstream direction” may refer to a direction approaching the mouth end of a smoker. The terms “upstream” and “downstream” may be used to describe the relative positions of the elements constituting a smoking article.
As used herein, the term “longitudinal direction” may refer to a direction corresponding to the longitudinal axis of a smoking article.
As used herein, the term “glass transition temperature (Tg)” may refer to a starting point of transition from a glass state to a rubber-like state. For example, the glass transition temperature may be analyzed using Differential Scanning calorimeter 250 purchased from TA Instruments and, specifically, be derived by analyzing an inflection point of a melting endothermic curve observed when heating a multifunctional material under a condition of 10° C./min.
According to an aspect of the present disclosure, provided is a smoking article including a first part including a medium and a wrapper wrapped around the medium and a second part including a multifunctional material having a glass transition temperature of higher than 180° C., wherein the wrapper includes a combustion improver, and the multifunctional material includes a moisturizer. A method of increasing the amount of a moisturizer included in a medium may be adopted to apply typical cigarettes to a heated type. However, problems with difficulties in the manufacturing process and with a wrapper wrapped around the medium getting wet by the moisturizer occurred. When using oil-resistant or water-resistant paper as the wrapper to solve such problems, there was a problem that combustion hardly occurred. According to an aspect of the present disclosure, with the combination of the wrapper including the combustion improver and the multifunctional material having a glass transition temperature of higher than 180° C., the smoking article not only enabling rich aerosol to deliver the medium component to a user using the moisturizer when heated but also facilitating smoke to deliver to a user due to smooth combustion when combusted may be implemented. According to another aspect of the present disclosure, with the combination of the wrapper including the combustion improver and the multifunctional material having a glass transition temperature of higher than 180° C., the smoking article usable in both heated and combustible types may be provided. Accordingly, consumers who interchangeably use heated tobacco and combustible tobacco may implement both smoking types using a single smoking article without the inconvenience of carrying both types of tobacco.
Hereinafter, the configuration of the present disclosure will be described in more detail with reference to the drawings.
Referring to
The first smoking article 100A, according to the present disclosure, includes the first part 110 and the second part 120. Specifically, the first part 110 and the second part 120 may be arranged in such an order along the longitudinal direction of the first smoking article 100A.
The first part 110, according to the present disclosure, may include the medium 110A capable of generating an aerosol and/or smoke as it is combusted. Specifically, the mainstream smoke generated as the first part 110 is combusted may be inhaled by a user through the second part 120, which will be described later, from the first part 110 in the longitudinal direction of the first smoking article 100A.
For example, the medium is not particularly limited and may be any substance capable of generating an aerosol and/or smoke commonly used in the related art to which the present disclosure pertains. Specifically, the medium may include tobacco raw materials, such as tobacco leaf pieces, tobacco stems, and the like, and materials processed therefrom. For a more specific example, the medium may include crushed tobacco leaves, expanded stems, tobacco shreds (for example, leaf tobacco shreds and reconstituted tobacco shreds), tobacco sheets (for example, reconstituted tobacco leaves), and the like.
According to some embodiments of the present disclosure, the medium may further include a flavoring agent. For example, the flavoring agent may be added to enhance flavor. Specifically, the flavoring agents may include licorice, sucrose, fructose syrup, ISO sweet, cocoa, lavender, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, mint oil, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, salvia, spearmint, ginger, cilantro, clove extract (or clove substance), coffee, or the like.
The first part 110, according to the present disclosure, includes the wrapper 110W wrapped around the medium 110A. Typically, the wrapper may affect the aesthetic characteristics of the exterior, mainstream smoke, sidestream smoke, puff count, combustion rate, flavor, ash, and the like. When additives are included in the wrapper as needed, specific purposes may be realized depending on the characteristics of the additives.
The wrapper 110W, according to the present disclosure, includes the combustion improver 112 to implement both combustible and heated types using a single smoking article. Specifically, the combustion improver may facilitate combustion when using the smoking article in the combustible type. In addition, when the smoking article is received in an aerosol-generating device and used in the heated type, the combustion improver 112 may be combined with the multifunctional material including the moisturizer, which will be described later, and allow rich aerosol and tobacco ingredients to deliver to a user.
According to some embodiments of the present disclosure, based on the total weight of the wrapper 110W, the combustion improver 112 may be included in an amount of: 0.5 wt % or more, 0.6 wt % or more, 0.7 wt % or more, 0.8 wt % or more, 0.9 wt % or more, 1.0 wt % or more, 1.1 wt % or more, 1.2 wt % or more, 1.3 wt % or more, 1.4 wt % or more, 1.5 wt % or more, 1.6 wt % or more, 1.7 wt % or more, 1.8 wt % or more, 1.9 wt % or more, 2.0 wt % or more, 2.1 wt % or more, 2.2 wt % or more, 2.3 wt % or more, 2.4 wt % or more, 2.5 wt % or more, 2.6 wt % or more, 2.7 wt % or more, 2.8 wt % or more, or 2.9 wt % or more; 3.0 wt % or less, 2.9 wt % or less, 2.8 wt % or less, 2.7 wt % or less, 2.6 wt % or less, 2.5 wt % or less, 2.4 wt % or less, 2.3 wt % or less, 2.2 wt % or less, 2.1 wt % or less, 2.0 wt % or less, 1.9 wt % or less, 1.8 wt % or less, 1.7 wt % or less, 1.6 wt % or less, 1.5 wt % or less, 1.4 wt % or less, 1.3 wt % or less, 1.2 wt % or less, 1.1 wt % or less, 1.0 wt % or less, 0.9 wt % or less, 0.8 wt % or less, 0.7 wt % or less, or 0.6 wt % or less; or in a range including any one value of the plurality of lower limit values above and any one value of the plurality of upper limit values above as the lower limit value and the upper limit value, respectively. Specifically, the amount of the combustion improver may be in the range of 0.5 to 3.0 wt %, 0.5 to 2.5 wt %, 0.8 to 2.5 wt %, 0.8 to 2.0 wt %, or 0.8 to 1.5 wt %. According to some embodiments of the present disclosure, when the amount of the combustion improver is less than the above numerical range, a problem that the medium is incompletely combusted when using the smoking article in the combustible type may occur due to the catalytic action. On the contrary, when the amount of the combustion improver is more than the above numerical range, changes may occur in the taste and flavor of the smoke, or the smoke may be unevenly generated.
For example, the combustion improver is not particularly limited, and any combustion improver commonly used in the field of the related art to which the present disclosure pertains may be used. Specifically, the combustion improver may include one or more selected from the group consisting of a citric acid-based compound, an acetic acid-based compound, a phosphate-based compound, and a tartaric acid-based compound. For example, the citric acid-based compound may include at least one of sodium citrate and potassium citrate, the acetic acid-based compound may include sodium acetate, the phosphate-based compound may include sodium phosphate, and the tartaric acid-based compound may include tartrate.
When using the smoking article in the combustible type, the second part 120, according to the present disclosure, may perform a filtration function on the aerosol and/or smoke generated in the first part 110. Specifically, the second part 120 may be placed downstream of the first part 110 and thus connected to a downstream end of the first part 110.
The second part 120, according to the present disclosure, includes the multifunctional material having a glass transition temperature of 180° C. or higher combined with the combustion improver included in the wrapper described above to implement both heated and combustible types using a single smoking article.
The multifunctional material, according to the present disclosure, may have a glass transition temperature (Tg) of higher than 180° C., which is preferably higher than 200° C., 210° C. or higher, 220° C. or higher, or 230° C. or higher. Specifically, the glass transition temperature may be higher than 200° C. and 300° C. or lower. A heater in an aerosol-generating device, which will be described later, may raise the temperature of the multifunctional material up to 200° C. For this reason, the glass transition temperature of the multifunctional material, according to the present disclosure, is more preferably higher than 200° C. Therefore, when the glass transition temperature of the multifunctional material is lower than the above numerical range, the smoking article is received in a receiving space in the aerosol-generating device, which will be described later. Thus, when heated by the heater, deformation or partial melting may occur, blocking or changing airflow and leading to a change in pressure drop. As a result, problems with draw resistance or a lack of uniformity in tobacco taste may occur. For example, a method of differential scanning calorimetry (DSC) analysis may be used as a method of analyzing the glass transition temperature of the multifunctional material.
According to some embodiments of the present disclosure, the multifunctional material 120A may be in contact with the medium 110A. Specifically, when the smoking article is inserted into the aerosol-generating device, which will be described later, and heated, the region of the heater is relatively reduced by the multifunctional material 120A being in contact with the medium 110A, which may be advantageous in terms of energy efficiency.
For example, the multifunctional material 120A may include one or more of a paper sheet, a cellulose filament, and a cotton sheet, which may specifically include a crimped paper sheet. According to some embodiments of the present disclosure, the crimped paper sheet may be well-impregnated with the moisturizer when included in the second part.
For example, the basis weight of the paper sheet may be: 30 gsm or more, 31 gsm or more, 32 gsm or more, 33 gsm or more, 34 gsm or more, 35 gsm or more, 36 gsm or more, 37 gsm or more, 38 gsm or more, 39 gsm or more, 40 gsm or more, 41 gsm or more, 42 gsm or more, 43 gsm or more, 44 gsm or more, 45 gsm or more, 46 gsm or more, 47 gsm or more, 48 gsm or more, 49 gsm or more, 50 gsm or more, 51 gsm or more, 52 gsm or more, 53 gsm or more, 54 gsm or more, 55 gsm or more, 56 gsm or more, 57 gsm or more, 58 gsm or more, 59 gsm or more, 60 gsm or more, 61 gsm or more, 62 gsm or more, 63 gsm or more, 64 gsm or more, 65 gsm or more, 66 gsm or more, 67 gsm or more, 68 gsm or more, 69 gsm or more, or 70 gsm or more; 70 gsm or less, 69 gsm or less, 68 gsm or less, 67 gsm or less, 66 gsm or less, 65 gsm or less, 64 gsm or less, 63 gsm or less, 62 gsm or less, 61 gsm or less, 60 gsm or less, 59 gsm or less, 58 gsm or less, 57 gsm or less, 56 gsm or less, 55 gsm or less, 54 gsm or less, 53 gsm or less, 52 gsm or less, 51 gsm or less, 50 gsm or less, 49 gsm or less, 48 gsm or less, 47 gsm or less, 46 gsm or less, 45 gsm or less, 44 gsm or less, 43 gsm or less, 42 gsm or less, 41 gsm or less, 40 gsm or less, 39 gsm or less, 38 gsm or less, 37 gsm or less, 36 gsm or less, 35 gsm or less, 34 gsm or less, 33 gsm or less, 32 gsm or less, 31 gsm or less, 30 gsm or less, 29 gsm or less, 28 gsm or less, 27 gsm or less, 26 gsm or less, 25 gsm or less, 24 gsm or less, 23 gsm or less, 22 gsm or less, or 21 gsm or less; or in a range including any one value of the plurality of lower limit values above and any one value of the plurality of upper limit values above as the lower limit value and the upper limit value, respectively. Specifically, the basis weight of the paper sheet may be in the range of 30 to 70 gsm, 40 to 70 gsm, 50 to 70 gsm, or 55 to 65 gsm. According to some embodiments of the present disclosure, when the basis weight of the paper sheet is less than the above numerical range, a problem that the paper sheet is hardly impregnated with a sufficient amount of the moisturizer may occur. On the contrary, when the basis weight of the paper sheet is more than the above numerical range, a problem that the paper sheet is hardly crimped, making a filter manufacturing process challenging, may occur.
According to some embodiments of the present disclosure, the thickness of the paper sheet may be in the range of 120 to 180 μm, 130 to 170 μm, 140 to 160 μm, or 145 to 155 μm. Specifically, when the thickness of the paper sheet is smaller than the above numerical range, a problem that the paper sheet tears easily may occur. On the contrary, when the thickness of the paper sheet is larger than the above numerical range, transportation may be challenging when manufacturing the filter. In addition, there may be a problem that the filter is manufactured with low roundness, leading to poor quality performance.
According to some embodiments of the present disclosure, the air permeability of the paper sheet may be in the range of 1,000 to 4,000 CU, 1,500 to 3,500 CU, 2,000 to 3,000 CU, 2,100 to 2,900 CU, or 2,400 to 2,600 CU. Specifically, when the air permeability of the paper sheet falls within the above numerical range, the paper sheet may be sufficiently impregnated with the moisturizer.
On the other hand, the bulk of the paper sheet is a thickness value with respect to the basis weight of the paper sheet. Typically, the higher the air permeability of the paper sheet, the higher the bulk of the paper sheet may be. For example, the bulk of the paper sheet may be in a range including: any one value of a plurality of lower limit values selected from 2 cm3/g or higher, 2.1 cm3/g or higher, 2.2 cm3/g or higher, 2.3 cm3/g or higher, 2.4 cm3/g or higher, 2.5 cm3/g or higher, 2.6 cm3/g or higher, 2.7 cm3/g or higher, 2.8 cm3/g or higher, 2.9 cm3/g or higher, 3.0 cm3/g or higher, 3.1 cm3/g or higher, 3.2 cm3/g or higher, 3.3 cm3/g or higher, 3.4 cm3/g or higher, 3.5 cm3/g or higher, 3.6 cm3/g or higher, 3.7 cm3/g or higher, 3.8 cm3/g or higher, or 3.9 cm3/g or higher as the lower limit value; and any one value of a plurality of upper limit values selected from 4.0 cm3/g or lower, 3.9 cm3/g or lower, 3.8 cm3/g or lower, 3.7 cm3/g or lower, 3.6 cm3/g or lower, 3.5 cm3/g or lower, 3.4 cm3/g or lower, 3.3 cm3/g or lower, 3.2 cm3/g or lower, 3.1 cm3/g or lower, 3.0 cm3/g or lower, 2.9 cm3/g or lower, 2.8 cm3/g or lower, 2.7 cm3/g or lower, 2.6 cm3/g or lower, 2.5 cm3/g or lower, 2.4 cm3/g or lower, 2.3 cm3/g or lower, 2.2 cm3/g or lower, or 2.1 cm3/g or lower as the upper limit value. Specifically, when the bulk of the paper sheet falls within the above numerical range, the paper sheet may be sufficiently impregnated with the moisturizer.
According to some embodiments of the present disclosure, the paper sheet may be formed by being rolled into a cylindrical shape and have a circumference in the range of 20 to 25 mm. For example, the paper sheet may be formed by crimping base paper and rolling the crimped paper or manufactured by rolling the base paper into a cylindrical shape when dried. In this case, the circumference of the paper sheet may be the circumference of the bottom surface of the cylindrical shape after being rolled.
For example, the cotton sheet may have a basis weight of 30 gsm or more and 70 gsm or less. In addition, the cotton sheet may have a thickness of 120 μm or larger and 180 μm or smaller. As a method of manufacturing the cotton sheet, a manufacturing method of a single-layer non-woven fabric or cross-web may be used. In addition, the cotton sheet may be processed in the same manner as in the case of the paper sheet so as to be included in the second part.
The multifunctional material, according to the present disclosure, includes the moisturizer to implement both the heated and combustible types using a single smoking article. A method of increasing the amount of a moisturizer included in a medium may be adopted to apply typical cigarettes to a heated type. However, problems with difficulties in the manufacturing process and with a wrapper wrapped around the medium getting wet by the moisturizer occurred. When using oil-resistant or water-resistant paper as the wrapper to solve such problems, there was a problem that combustion hardly occurred. According to an aspect of the present disclosure, with the combination of the wrapper including the combustion improver and the multifunctional material including the moisturizer, the moisturizer is enabled to be included in a non-combusted part when using the smoking article in the combustible type, thus not only having excellent manufacturability but also not requiring water-resistant/oil-resistant paper. In addition, when using the smoking article in the heated type, both the medium and the multifunctional material including the moisturizer are heated simultaneously, thus allowing rich aerosol and the medium component to deliver to a user.
According to some embodiments of the present disclosure, based on the total length of the multifunctional material, the moisturizer may be included in an amount of: 1 mg/mm or more, 2 mg/mm or more, 3 mg/mm or more, 4 mg/mm or more, 5 mg/mm or more, 6 mg/mm or more, 7 mg/mm or more, 8 mg/mm or more, or 9 mg/mm or more; 10 mg/mm or less, 9 mg/mm or less, 8 mg/mm or less, 7 mg/mm or less, 6 mg/mm or less, 5 mg/mm or less, 4 mg/mm or less, 3 mg/mm or less, or 2 mg/mm or less; or in a range including any one value of the plurality of lower limit values above and any one value of the plurality of upper limit values above as the lower limit value and the upper limit value, respectively. Specifically, the amount of the moisturizer included may be in the range of 1 to 10 mg/mm, 2 to 9 mg/mm, 3 to 8 mg/mm, 4 to 7 mg/mm, or 5 to 6 mg/mm. According to some embodiments of the present disclosure, when the amount of the moisturizer included is less than the above numerical range, a problem with the aerosol being insufficiently delivered to a user may occur when using the smoking article in the heated type because the amount of atomization generated is insufficient. On the contrary, when the amount of the moisturizer included is more than the above numerical range, the moisturizer may ooze out, thus contaminating the smoking article.
According to non-limiting examples, the moisturizer may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol.

For example, the average coarseness of the pulp fiber 122 may be: 13 mg/100 m or higher, 14 mg/100 m or higher, 15 mg/100 m or higher, 16 mg/100 m or higher, 17 mg/100 m or higher, 18 mg/100 m or higher, 19 mg/100 m or higher, 20 mg/100 m or higher, 21 mg/100 m or higher, 22 mg/100 m or higher, 23 mg/100 m or higher, 24 mg/100 m or higher, 25 mg/100 m or higher, 26 mg/100 m or higher, 27 mg/100 m or higher, or 28 mg/100 m or higher; 40 mg/100 m or lower, 39 mg/100 m or lower, 38 mg/100 m or lower, 37 mg/100 m or lower, 36 mg/100 m or lower, 35 mg/100 m or lower, 34 mg/100 m or lower, 33 mg/100 m or lower, 32 mg/100 m or lower, 31 mg/100 m or lower, 30 mg/100 m or lower, 29 mg/100 m or lower, or 28 mg/100 m or lower; or in a range including any one value of the plurality of lower limit values above and any one value of the plurality of upper limit values above as the lower limit value and the upper limit value, respectively. More specifically, the average coarseness of the pulp fiber may be 13 mg/100 m or higher, in the range of 13 to 29 mg/100 m, in the range of 14 to 29 mg/100 m, in the range of 15 to 28 mg/100 m, in the range of 16 to 28 mg/100 m, in the range of 17 to 28 mg/100 m, in the range of 18 to 28 mg/100 m, in the range of 19 to 28 mg/100 m, in the range of 20 to 28 mg/100 m, in the range of 21 to 28 mg/100 m, in the range of 22 to 28 mg/100 m, in the range of 23 to 28 mg/100 m, in the range of 24 to 28 mg/100 m, in the range of 25 to 28 mg/100 m, in the range of 26 to 28 mg/100 m, or in the range of 27 to 28 mg/100 m.
The second part 120, according to the present disclosure, may include wrapping paper 120W wrapped around the multifunctional material 120A. For example, the wrapping paper 120W may include filter wrapping paper wrapped around the multifunctional material, tip paper, or a combination thereof. In this case, the tip paper may be wrapped around the filter wrapping paper.
Referring to
The second part 120 of the second smoking article 100B, according to the present disclosure, may include a first region 120R1 and a second region 120R2 that differs from the first region 120R1. In this case, the first region 120R1 may be in contact with the first part 110. In addition, the first region 120R1 may include the multifunctional material 120A. According to some embodiments of the present disclosure, the first region 120R1 includes the multifunctional material 120A while being in contact with the first part 110. Thus, when the smoking article is inserted into the aerosol-generating device, which will be described later, and heated, the region of the heater is relatively reduced, which may be advantageous in terms of energy efficiency.
For example, the second region 120R2 may include any one of a cellulose acetate filter, a paper tube, and a hollow filter. The cellulose acetate filter may function as a filter in the combustible type. In this case, the cellulose acetate filter may have a glass transition temperature of 200° C. or lower. For this reason, when placed in the first region 120R1, a problem of deformation or melting may occur. The paper tube may be a paper tube formed from paper material and having a hollow cylindrical shape. Specifically, the inner surface of the paper tube may be coated with polylactic acid. According to some embodiments of the present disclosure, the inner surface of the paper tube may be coated with polylactic acid, thus more effectively cooling tobacco mainstream smoke and/or aerosol generated by combusting the first part or heating the first and second parts. The hollow filter through which the atomization moves may be a hollow-structured cellulose acetate filter.
According to another aspect of the present disclosure, provided is an aerosol-generating system including an aerosol-generating device including a receiving space therein and a proximal end provided on one end thereof and the smoking article, according to some embodiments, configured to be inserted into the receiving space, wherein the receiving space includes a first space adjacent to the proximal end and a second space that differs from the first space, the first space is filled with the first part, and the second space is filled with the second part. The “first space adjacent to the proximal end” herein may be, for example, defined as a space from one end of the proximal end by the length of the first part so as to be sufficiently filled with the first part. In addition, the smoking article, according to some embodiments, described above may be replaced with an “aerosol-generating article”.
Referring to
The aerosol-generating device 200, according to the present disclosure, includes the receiving space H therein and the proximal end ME provided on one end thereof.
The receiving space H, according to the present disclosure, may be a space into which the smoking article, according to some embodiments, is inserted. Specifically, the receiving space H may include the first space H1 and the second space H2 that differs from the first space H1. In this case, the first space H1 is filled with the first part 110, and the second space H2 is filled with the second part 120.
Both the first part 110 and the second part 120, with which the first space H1 and the second space H2 are respectively filled, may be heated simultaneously by the heater 220, which will be described later, thus enabling the aerosol generated as the moisturizer is heated to deliver the medium component to a user in a first direction D1. In this case, the first direction D1 may be the direction in which the aerosol is delivered, specifically from the second part 120 to the first part 110. In other words, when using the smoking article, according to the present disclosure, in the heated type, the aerosol may be delivered from the second part 120 to the first part 110, unlike when using the smoking article in the combustible type.
The proximal end ME, according to the present disclosure, may be a part making contact with the mouth of a user. For example, the proximal end ME, provided on one end of the aerosol-generating device 200, may be variously modified in shapes. Alternatively or additionally, the proximal end ME may include the cellulose acetate filter.
The aerosol-generating device 200, according to the present disclosure, may further include the heater 220 configured to heat the first part 110 and the second part 120. Specifically, the heater 220 may heat both the first part 110 and the second part 120 inserted into the receiving space H. More specifically, the heater 220 may heat each portion of the first part 110 and the second part 120. In this case, the second part 120 includes the multifunctional material having a glass transition temperature of higher than 180° C., so the multifunctional material may not be melted by the heater 220. For example, the maximum temperature raised by applying the heater 220 may be 300° C. According to some embodiments of the present disclosure, the aerosol generated by the moisturizer included in the multifunctional material may enable the medium component in the first part 110 to deliver toward the proximal end ME by heating both the first part 110 and the second part 120.
Referring to
The aerosol-generating device 200, according to the present disclosure, may further include the heater 220 configured to heat the first part 110 and the first region 120R1. Specifically, the heater 220 may heat the first region 120R1 and a portion of the first part 110. In this case, the heater configured to heat the second region 120R2 may not be provided in the aerosol-generating device 200. When the heater configured to heat the second region 120R2 is provided, a problem that the cellulose acetate filter in the second region 120R2 is deformed or melted by heat may occur. Although the paper tube may not be melted by the heater even when included in the second region 120R2, the heater configured to heat only the first part 110 and the first region 120R1 is preferably provided in terms of energy efficiency. In this case, a portion of the first part 110 may be in contact with the first region 120R1.
The heater 220, according to the present disclosure, may be appropriately placed in a position such that the first part 110 and the second part 120 are heated. For example, the heater 220 may be placed on both sides of the smoking article 100 configured to be inserted into the receiving space H. For example, the heater 220 may also be modified as an internally heated type or externally heated type. For example, the heater 220 may be implemented as an electric resistance heater or an induction-heated type.
The aerosol-generating device 200, according to the present disclosure, may further include a housing, a control part, and a battery.
The housing, according to the present disclosure, may form the exterior of the aerosol-generating device 200 and may form the receiving space H configured to receive the smoking article 100 according to some embodiments.
The control part, according to the present disclosure, may be configured to control the overall operation of the aerosol-generating device. For example, the control part may be configured to control the operation of the heater and the battery or to control the operation of other components included in the aerosol-generating device. Specifically, the control part may control the power supplied by the battery, the heating temperature of the heater, and the like. In addition, the control part may check the status of each configuration of the aerosol-generating device to determine whether the aerosol-generating device is operable or inoperable.
The control part, according to the present disclosure, may be implemented by at least one processor. The processor may be implemented as an array of multiple logic gates or as a combination of a general-purpose microprocessor and memory in which programs enabled to be executed on this microprocessor are stored.
The battery, according to the present disclosure, may supply power usable in operating the aerosol-generating device 200. For example, the battery may supply power to the heater or may supply the power necessary for the control part to operate. In addition, the battery may supply the power necessary for electrical components such as a display, a sensor, a motor, and the like installed in the aerosol-generating device to operate.
Although the preferred embodiments of the present disclosure have been described in detail hereinabove, the scope of the present disclosure is not limited thereto. That is, several modifications and alternatives made by those skilled in the art using a basic concept of the present disclosure as defined in the appended claims fall within the scope of the present disclosure.
