Description

Technical Field

[0001] This invention relates to a cigarette comprising a tobacco stick and a filter stick. Background Technology

[0002] In recent years, there has been an increasing demand for alternative methods to overcome the drawbacks of regular cigarettes. For example, there is a growing need for methods that generate aerosols by heating aerosol-generating substances within cigarettes, rather than by burning the cigarettes.

[0003] Cigarettes include filters that either filter out specific components contained in the aerosol or cool the aerosol. The problem is that if the filter's performance is too high, the amount of aerosol transferred is low; if the performance is too low, it cannot filter out the specific components contained in the aerosol.

[0004] Therefore, research is underway on filters that can achieve appropriate performance by changing the components that make up the filter or by changing the structure of the filter. Summary of the Invention

[0005] The problem the invention aims to solve

[0006] One or more embodiments provide a cigarette in which sucrose constitutes the cooling substance of the cooling section. The technical problem to be solved by this embodiment is not limited to the technical problem described above, and other technical problems can be deduced from the following embodiments.

[0007] means for solving problems

[0008] A cigarette is disclosed, comprising: a tobacco stick; and a filter stick connected to the downstream end of the tobacco stick.

[0009] In this embodiment, a portion of the filter rod is composed of a cooling section, which contains sucrose as a cooling substance.

[0010] A cigarette is provided, comprising a tobacco stick and a filter rod connected to the downstream end of the tobacco stick, wherein a portion of the filter rod is composed of a cooling section containing sucrose as a cooling substance, the sucrose absorbing heat from heated aerosols generated in the tobacco stick and undergoing a phase change, the filter rod including a cooling section, a tubular section, and a mouthpiece; the cooling section is connected to the downstream end of the tobacco stick, the tubular section is connected to the downstream end of the cooling section, the mouthpiece is connected to the downstream end of the tubular section, and the cooling substance is bead-shaped with minute protrusions formed on at least a portion of its surface.

[0011] Invention Effects

[0012] According to the present invention, heated aerosols can be effectively cooled by using sucrose, which constitutes the cooling section, as the cooling substance. When the heated aerosol passes through the cooling section, the temperature of the sucrose reaches a temperature above its melting point, thus causing a phase change in the sucrose. During this process, the sucrose absorbs heat from the surrounding environment, thereby cooling the heated aerosol.

[0013] In addition, due to the property of sucrose to absorb moisture from the surrounding environment, the moisture absorbed by the sucrose will be added to the aerosol passing through the cooling section, thus increasing the amount of aerosol. Attached Figure Description

A portion of the filter stick comprises a cooling section containing sucrose as a cooling substance.

[0022] The terminology used in the embodiments has been selected as widely used and common terms as possible, taking into account the functionality of the invention. However, these terms may be changed based on the intent of those skilled in the art, precedents, or the emergence of new technologies. Furthermore, in certain cases, the applicant has arbitrarily selected some terms; in such cases, the meanings of the selected terms will be described in detail in the description of the invention. Therefore, the terminology used in this invention should be defined based on its meaning and the overall content of the invention, and not merely on the name of the term.

[0023] Throughout this specification, the phrase "includes" a component means that, unless there is a description of its characteristics to the contrary, other components may also be included, rather than excluding other components. Furthermore, terms such as "...section" and "...module" used in this specification refer to a unit that processes at least one function or action, which can be implemented in hardware or software, or a combination of hardware and software.

[0024] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings to enable those skilled in the art to readily implement the invention. However, the present invention is not limited to the embodiments described herein, but can be implemented in various different ways.

[0025] In the following embodiments, the terms "upstream" or "downstream" are used to indicate the relative positions between the segments that make up a cigarette. When a user inhales air from the cigarette, the portion from which air enters the cigarette from the outside is the "upstream," and the portion from which air flows out of the cigarette is the "downstream." When using a cigarette, the user may bite down on the downstream end of the cigarette. Alternatively, the term "end" may also be referred to as "terminus."

[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0027] Figures 1 to 3 This is a diagram showing an example of a cigarette being inserted into an aerosol generating device.

[0028] Reference Figure 1 The aerosol generating device 10000 includes a battery 11000, a control unit 12000, and a heater 13000. (See reference...) Figure 2 and Figure 3 The aerosol generating device 10000 also includes a vaporizer 14000. Additionally, a cigarette 20000 can be inserted into the internal space of the aerosol generating device 10000.

[0029] Figures 1 to 3The aerosol generating apparatus 10000 shown only includes components relevant to this embodiment. Therefore, those skilled in the art should understand that the aerosol generating apparatus 10000 may also include components other than those shown in this embodiment. Figures 1 to 3 Other common constituent elements besides those shown.

[0030] in addition, Figure 2 and Figure 3 The aerosol generating apparatus 10000 shown includes a heater 13000, but the heater 13000 may be omitted if necessary.

[0031] Figure 1 The image shows the battery 11000, control unit 12000, and heater arranged in a row. Additionally, Figure 2 The diagram shows the battery 11000, control unit 12000, carburetor 14000, and heater 13000 arranged in a row. Additionally, Figure 3 The vaporizer 14000 and heater 13000 are shown arranged side by side. However, the internal structure of the aerosol generating device 10000 is not limited to this. Figures 1 to 3 As shown. In other words, the configuration of the battery 11000, control unit 12000, heater 13000 and vaporizer 14000 can be changed according to the design of the aerosol generating device 10000.

[0032] When cigarette 20000 is inserted into aerosol generating device 10000, aerosol generating device 10000 activates heater 13000 and / or vaporizer 14000, thereby generating aerosol from cigarette 20000 and / or vaporizer 14000. The aerosol generated by heater 13000 and / or vaporizer 14000 is delivered to the user via cigarette 20000.

[0033] If necessary, even if the cigarette 20000 is not inserted into the aerosol generating device 10000, the aerosol generating device 10000 can still heat the heater 13000.

[0034] Battery 11000 supplies power to operate aerosol generating apparatus 10000. For example, battery 11000 can power heater 13000 or vaporizer 14000, and can supply power to control unit 12000. In addition, battery 11000 can supply power to displays, sensors, motors, etc. installed in aerosol generating apparatus 10000.

[0035] The control unit 12000 provides overall control of the operation of the aerosol generating device 10000. Specifically, in addition to controlling the battery 11000, heater 13000, and vaporizer 14000, the control unit 12000 also controls the operation of other structures included in the aerosol generating device 10000. Furthermore, the control unit 12000 can determine whether the aerosol generating device 10000 is in an operational state by checking the status of each structure of the aerosol generating device 10000.

[0036] The control unit 12000 includes at least one processor. The processor can be composed of multiple logic gate arrays, or it can be implemented using a combination of a general-purpose microprocessor and a memory storing a program executable by the microprocessor. Furthermore, as will be understood by those skilled in the art to which this embodiment pertains, it can also be implemented in other forms of hardware.

[0037] The heater 13000 can be heated by power supplied by the battery 11000. For example, when a cigarette is inserted into the aerosol generating device 10000, the heater 13000 can be located inside the cigarette. Therefore, the heated heater 13000 can raise the temperature of the aerosol generating substances inside the cigarette.

[0038] Heater 13000 can be a resistance heater. For example, heater 13000 may include a conductive track, and heater 13000 can be heated by current flowing in the conductive track. However, heater 13000 is not limited to the above example, and there are no special limitations as long as it can heat to the desired temperature. Here, the desired temperature can be preset in the aerosol generating device 10000, or it can be set by the user.

[0039] On the one hand, as another example, heater 13000 can be an induction heating heater. Specifically, heater 13000 may include a conductive coil for heating cigarettes in an induction heating manner, and the cigarettes may include a heat-sensitive element capable of being heated by the induction heating heater.

[0040] For example, heater 13000 may include tubular heating elements, plate heating elements, needle heating elements, or rod heating elements, which can heat the inside or outside of cigarette 20000 depending on the shape of the heating elements.

[0041] Furthermore, the aerosol generating apparatus 10000 may be equipped with multiple heaters 13000. In this case, the multiple heaters 13000 may be configured to be inserted inside the cigarette 20000, or they may be configured to be located outside the cigarette 20000. Alternatively, some of the multiple heaters 13000 may be configured to be inserted inside the cigarette 20000, while the others may be located outside the cigarette 20000. Additionally, the shape of the heaters 13000 is not limited to... Figures 1 to 3 The shape shown can also be made into many other shapes.

[0042] The vaporizer 14000 generates an aerosol by heating a liquid composition, and the generated aerosol can be delivered to the user via the cigarette 20000. In other words, the aerosol generated by the vaporizer 14000 can move along the airflow channel of the aerosol generating device 10000, and the airflow channel can be configured to allow the aerosol generated by the vaporizer 14000 to be delivered to the user via the cigarette.

[0043] For example, the vaporizer 14000 may include a liquid storage unit, a liquid transfer unit, and a heating element, but is not limited thereto. For example, the liquid storage unit, the liquid transfer unit, and the heating element may be provided as independent modules in the aerosol generating apparatus 10000.

[0044] The liquid storage unit is capable of storing a liquid composition. For example, the liquid composition may be a liquid containing tobacco substances including volatile tobacco flavor components, or it may be a liquid containing non-tobacco substances. The liquid storage unit may be made so that it can be detached from or installed on the vaporizer 14000, or it may be made integral with the vaporizer 14000.

[0045] For example, the liquid composition may include water, solvent, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures. Fragrances may include, but are not limited to, menthol, peppermint oil, spearmint oil, and various fruity aroma components. Flavorings may include ingredients capable of providing the user with a variety of fragrances or flavors. Vitamin mixtures may be, but are not limited to, a mixture of at least one of vitamins A, B, C, and E. Additionally, the liquid composition may include aerosol forming agents such as glycerin and propylene glycol.

[0046] The liquid transfer unit is capable of transferring the liquid composition from the liquid storage section to the heating element. For example, the liquid transfer unit can be a core made of materials such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic, but is not limited to these.

[0047] A heating element is a component used to heat a liquid composition transferred through a liquid transfer unit. For example, the heating element can be a metal hot wire, a metal hot plate, a ceramic heater, etc., but is not limited to these. Alternatively, the heating element can be constructed from a conductive heating wire, such as nickel-chromium wire, and can be arranged in a structure wound around the liquid transfer unit. The heating element can be heated by an electric current supply and transfer heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, an aerosol can be generated.

[0048] For example, the vaporizer 14000 may be called an electronic cartomizer or an atomizer, but is not limited to these terms.

[0049] On one hand, the aerosol generating device 10000 may also include other general structures besides the battery 11000, control unit 12000, heater 13000, and vaporizer 14000. For example, the aerosol generating device 10000 may include a display capable of outputting visual information and / or a motor for outputting tactile information. Additionally, the aerosol generating device 10000 may include at least one sensor (a suction sensor, a temperature sensor, and a cigarette insertion sensor). Furthermore, the aerosol generating device 10000 may be configured to allow external air to flow in or internal gas to flow out even when the cigarette 20000 is inserted.

[0050] Although Figures 1 to 3 Although not shown, the aerosol generating device 10000 can be configured as a system with a separately provided bracket. For example, the bracket can be used to charge the battery 11000 of the aerosol generating device 10000. Alternatively, the heater 13000 can also be used for heating when the bracket is combined with the aerosol generating device 10000.

[0051] Cigarette 20000 can be similar to ordinary combustible cigarettes. For example, cigarette 20000 can be divided into a first part including aerosol-generating substances and a second part including a filter, etc. Alternatively, the second part of cigarette 20000 may also include aerosol-generating substances. For example, aerosol-generating substances made in the form of granules or capsules can be inserted into the second part.

[0052] The entire first part can be inserted inside the aerosol generating device 10000, while the second part can be exposed. Alternatively, only a portion of the first part can be inserted inside the aerosol generating device 10000, or the entire first part and a portion of the second part can be inserted. The user can inhale the aerosol while holding the second part in their mouth. At this time, external air passes through the first part, thereby generating an aerosol, which is then delivered to the user's mouth via the second part.

[0053] As an example, external air can flow in through at least one air passage formed in the aerosol generating device 10000. For example, the opening and closing of the air passage formed in the aerosol generating device 10000 and / or the size of the air passage can be adjusted by the user. Thus, the user can adjust the amount of vaporization, the smoking sensation, etc. As another example, external air can also flow into the interior of the cigarette 20000 through at least one hole formed on the surface of the cigarette 20000.

[0054] The following is for reference Figure 4 The example of 20,000 cigarettes will be used to illustrate this.

[0055] Figure 4This is a diagram showing an example of a cigarette.

[0056] Reference Figure 4 Cigarette 20000 includes tobacco stick 21000 and filter stick 22000. (See reference) Figures 1 to 3 The first part includes a tobacco stick 21000, and the second part 32000 includes a filter stick 22000.

[0057] Figure 4 The filter rod 22000 shown is a single segment, but is not limited thereto. In other words, the filter rod 22000 may be composed of multiple segments. For example, the filter rod 22000 may include segments for cooling aerosols and segments for filtering specified components in the aerosols. In addition, depending on the requirements, the filter rod 22000 may also include at least one segment that performs other functions.

[0058] Cigarette 20000 can be wrapped with at least one wrapping paper 24000. The wrapping paper 24000 may have at least one hole for allowing external air to flow in or internal gas to flow out. For example, cigarette 20000 can be wrapped with one wrapping paper 24000. As another example, cigarette 20000 can also be wrapped with two or more wrapping papers 24000 stacked together. For instance, a first wrapping paper can be used to wrap the tobacco stick 21000, and a second wrapping paper can be used to wrap the filter stick 22000. Furthermore, the tobacco stick 21000 and filter stick 22000, each wrapped with a single wrapping paper, can be combined and then wrapped with a third wrapping paper to form the entire cigarette 20000. If the tobacco stick 21000 or filter stick 22000 is composed of multiple segments, each segment can be wrapped with a single wrapping paper. Furthermore, the entire cigarette 20000, composed of segments wrapped with single wrapping papers, can be wrapped with other wrapping papers.

[0059] The tobacco stick 21000 contains aerosol-generating substances. For example, the aerosol-generating substances may include, but are not limited to, at least one of glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. Additionally, the tobacco stick 21000 may contain other additives such as flavoring agents, humectants, and / or organic acids. Furthermore, flavoring liquids such as menthol or humectants may be added to the tobacco stick 21000 by spraying it into the tobacco stick 21000.

[0060] The tobacco stick 21000 can be manufactured in various ways. For example, the tobacco stick 21000 can be made of sheet material or strand material. Alternatively, the tobacco stick 21000 can be made from tobacco leaves obtained by slicing tobacco sheets into small pieces. Furthermore, the tobacco stick 21000 can be surrounded by a heat-conducting material. For example, the heat-conducting material can be a metal foil such as aluminum foil, but is not limited to this. As an example, the heat-conducting material surrounding the tobacco stick 21000 can evenly distribute the heat transferred to the tobacco stick 21000, thereby increasing the thermal conductivity applied to the tobacco stick, which can improve the flavor of the tobacco. Additionally, the heat-conducting material surrounding the tobacco stick 21000 can function as a heat-sensor heated by an induction heater. In this case, although not shown in the figure, the tobacco stick 21 may include an additional heat-sensor in addition to the heat-conducting material surrounding the exterior.

[0061] The filter rod 22000 can be a cellulose acetate tow filter. On one hand, the shape of the filter rod 22000 is not limited. For example, the filter rod 22000 can be a cylindrical rod or a hollow tubular rod. Additionally, the filter rod 22000 can be a recessed rod. If the filter rod 22000 is composed of multiple segments, at least one of the segments can be made into a different shape.

[0062] The filter rod 22000 can be made to produce fragrance. As an example, flavoring liquid can be sprayed into the filter rod 22000, or individual fibers coated with flavoring liquid can be inserted into the interior of the filter rod 22000.

[0063] Additionally, the filter rod 22000 may include at least one capsule 23000. Here, the capsule 23000 can function to generate fragrance and also to generate aerosols. For example, the capsule 324000 may be a structure consisting of an internal solution containing fragrance encapsulated by a membrane. The capsule 324000 may have a spherical or cylindrical shape, but is not limited to these.

[0064] If the filter rod 22000 includes a section for cooling aerosols, the cooling section may be made of a polymer or a biodegradable polymer. For example, the cooling section may be made of pure polylactic acid, but is not limited to this. Alternatively, the cooling section may be made of a multi-perforated cellulose acetate tow filter. However, the cooling section is not limited to the above examples, and there are no restrictions as long as the aerosol can perform a cooling function.

[0065] On the one hand, although Figure 4Not shown, one embodiment of the cigarette 20000 may further include a front-end filter. The front-end filter is located on the side of the tobacco stick 21000 facing the filter stick 22000. The front-end filter can prevent the tobacco stick 21000 from detaching to the outside and can also prevent liquefied aerosol from flowing from the tobacco stick 21000 into the aerosol generating device during smoking.

[0066] Figure 5 This is a diagram illustrating an example of a cigarette including a cooling section according to one embodiment.

[0067] Reference Figure 5 The cigarette 5 includes: a tobacco rod 510; and a filter rod 520 connected to the downstream end of the tobacco rod 510. The filter rod 520 may include a cooling section 521, a tubular section 522, and a mouthpiece section 523.

[0068] like Figure 5 As shown, in one embodiment, the cooling section 521 can be connected to the downstream end of the tobacco stick 510, the tubular section 522 can be connected to the downstream end of the cooling section 521, and the mouthpiece 523 can be connected to the downstream end of the tubular section 522. That is, the positions of each segment can be arranged in the order of tobacco stick 510, cooling section 521, tubular section 522, and mouthpiece 523.

[0069] In other embodiments, the tubular portion 522 may be connected to the downstream end of the tobacco stick 510, the cooling portion 521 may be connected to the downstream end of the tubular portion 522, and the mouthpiece portion 523 may be connected to the downstream end of the cooling portion 521. That is, the segments may be arranged in the order of tobacco stick 510, tubular portion 522, cooling portion 521, and mouthpiece portion 523.

[0070] However, the types of filter segments included in the filter rod 520 and the order in which the filter segments constituting the filter rod 520 are arranged are not limited to this.

[0071] On the one hand, cigarette 5 can be packaged with multiple wrapping papers. These multiple wrapping papers can be made of ordinary paper rolls, which can be perforated or non-perforated paper rolls.

[0072] For example, the tobacco stick 510 can be wrapped with a first wrapping paper, and the tubular part 522 can be wrapped with a second wrapping paper. In addition, the cooling part 521 can be wrapped with a third wrapping paper, and the mouthpiece part 523 can be wrapped with a fourth wrapping paper.

[0073] A fifth wrapping paper can be used to wrap the exterior of the first, second, and third wrapping papers. In other words, the tobacco stick 510, tubular portion 522, and cooling portion 521 of cigarette 5 can be re-wrapped with the fifth wrapping paper. Furthermore, a sixth wrapping paper can be used to wrap at least a portion of the fifth wrapping paper and the exterior of the fourth wrapping paper. In other words, at least a portion of the cooling portion 521 and the filter tip 523 of cigarette 5 can be re-wrapped with the sixth wrapping paper.

[0074] The diameter of the cigarette 5 can be in the range of 5mm to 9mm, and the length can be about 48mm, but is not limited to these. For example, the length of the tobacco stick 510 can be about 12mm, the length of the tubular part 522 can be about 10mm, the length of the cooling part 521 can be about 14mm, and the length of the mouthpiece 523 can be about 12mm, but is not limited to these.

[0075] The tobacco stick 510 contains an aerosol-generating substance. For example, the aerosol-generating substance may contain at least one of glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol.

[0076] In addition, tobacco stick 510 may contain other additives such as flavoring agents, humectants, and / or organic acids. For example, flavoring agents may include licorice, sucrose, fructose syrup, isosweet, cocoa powder, lavender, cinnamon, cardamom, celery, fenugreek, balsam bark, sandalwood, bergamot, geranium, honey extract, rose oil, vanilla, lemon oil, orange oil, peppermint oil, cinnamon, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, sage, spearmint, ginger, coriander, or coffee, etc. Humectants may include glycerin or propylene glycol, etc.

[0077] As one example, the tobacco stick 510 may be filled with reconstituent tobacco sheets. As another example, the tobacco stick 510 may be filled with tobacco leaves. The tobacco leaves can be generated by shredding the reconstituent tobacco sheets. As yet another example, the tobacco stick 310 may be filled with multiple tobacco shreds formed from finely shredded reconstituent tobacco sheets. For example, the tobacco stick 310 can be formed by combining the tobacco shreds in the same direction (parallel direction) or randomly.

[0078] In addition, before wrapping the tobacco sticks 510 in wrapping paper, flavoring liquids such as menthol or humectants can be added to the tobacco sticks 510 by spraying them into the center.

[0079] The tubular portion 522 can be a cellulose acetate filter. For example, the tubular portion 522 can be a hollow tubular structure. The length of the tubular portion 522 can be suitably used in the range of 4 mm to 30 mm, but is not limited thereto. The length of the tubular portion 522 is preferably 10 mm, but is not limited thereto. The diameter of the hollow portion included in the tubular portion 522 can be suitably used in the range of 2 mm to 4.5 mm, but is not limited thereto.

[0080] When manufacturing the tubular portion 522, the hardness of the tubular portion 522 can be adjusted by adjusting the content of the plasticizer. In addition, when manufacturing the tubular portion 522, structures such as membranes or tubes made of the same or different materials can be inserted into the interior of the tubular portion 522 (e.g., hollow).

[0081] Cellulose acetate can be used to manufacture the tubular portion 522. This prevents the internal contents of the tobacco stick 510 from being squeezed to the rear when the heater is inserted, and also produces an aerosol cooling effect.

[0082] The cooling section 521 may contain sucrose (or sucbiose) as a cooling substance. Sucrose has a melting point of approximately 160°C to 180°C. If the temperature of the sucrose exceeds its melting point, it will undergo caramelization, during which it will absorb heat from its surroundings.

[0083] The cooling section 521 cools the aerosol generated by the heater heating the tobacco stick 510. Therefore, the user can inhale the aerosol cooled to a suitable temperature.

[0084] Specifically, when the cigarette 5 is inserted into the aerosol generating device, the aerosol generating device activates the heater to heat the tobacco stick 510 of the cigarette 5. When the user inhales air while holding the mouthpiece 523 of the cigarette 5 inserted into the aerosol generating device in their mouth, air flows into the inside of the cigarette 5 from the outside, and aerosol is generated as the air flowing into the cigarette 5 passes through the heated tobacco stick 510.

[0085] As the aerosol generated in the tobacco stick 510 passes through the cooling section 521, the temperature of the sucrose contained in the cooling section 521 as a cooling substance rises. When the sucrose reaches its melting point or a higher temperature, it undergoes a caramelization reaction. During this process, the sucrose can cool the heated aerosol by absorbing heat from the surrounding environment. Therefore, the user can inhale the aerosol cooled to a suitable temperature.

[0086] Furthermore, the sucrose contained in the cooling section 521 has the property of absorbing ambient moisture without releasing it. Therefore, the moisture absorbed by the sucrose is added to the aerosol passing through the cooling section 521, thereby increasing the amount of aerosol and maintaining the amount of aerosol until the latter half of the smoking process.

[0087] In addition, if the sucrose is a highly concentrated sugar concentrate, its high osmotic pressure and high preservative properties ensure its stability during storage.

[0088] In one embodiment, the sucrose contained in the cooling section 521 may have a bead-like, sheet-like, or block-like shape.

[0089] Bead-shaped sucrose can be spherical or fillet-shaped. Flake-shaped sucrose can be made of either porous paper or edible film. Block-shaped sucrose can be cylindrical, tubular, or honeycomb-shaped.

[0090] The length or diameter of the cooling section 521 can vary depending on the shape of the cigarette 5. For example, the length of the cooling section 521 can be appropriately adopted in the range of 7 mm to 20 mm. Preferably, the length of the cooling section 521 can be about 14 mm, but it is not limited thereto.

[0091] On the one hand, such as Figure 5 As shown, the cooling section 52 is located upstream of the cigarette 5 compared to the tubular section 522 and the mouthpiece section 523, thus preventing the tubular section 522 and the mouthpiece section 523 from melting or shrinking due to heat.

[0092] Figure 6 This is an example diagram illustrating a bead-shaped cooling material according to one embodiment.

[0093] Reference Figure 6 The cooling unit 600 may include a first filter element 610, a second filter element 620, and a cooling substance 630.

[0094] The first filter element 610 may be located at one end of the cooling section 600, and the second filter element 620 may be located at the other end of the cooling section 600. Alternatively, the first filter element 610 and the second filter element 620 may be separated by a predetermined distance to form a cavity between them. A cooling substance 630 containing sucrose may be located within this cavity.

[0095] In one embodiment, the first filter element 610 and the second filter element 620 may be hollow tubular structures, but the shapes of the first filter element 610 and the second filter element 620 are not limited thereto.

[0096] The cooling material 630 located in the cavity between the first filter element 610 and the second filter element 620 can be bead-shaped. The bead-shaped cooling material 630 can be spherical or rounded.

[0097] In one embodiment, bead-shaped cooling material 630 can be produced by laminating a sucrose layer onto sucrose seeds using a tangential spray or a top spray method. The bead-shaped cooling material 630 produced in this way can have a spherical or rounded shape.

[0098] Additionally, the surface of the bead-like cooling material 630 can be coated. Film-forming polymers, gums, or starches can be used as coating agents for the surface of the cooling material 630. For example, shellac, hydroxypropyl methylcellulose (HPMC), corn starch, or combinations thereof can be used as coating agents for the surface of the cooling material 630. Preferably, shellac can be used as the coating agent for the surface of the cooling material 630. Coating the surface of the cooling material 630 facilitates the insertion of the cooling material 630 into the cooling section 600 and improves the storage convenience of the cooling material 630.

[0099] Furthermore, at least a portion of the surface of the cooling material 630 may have minute protrusions. Because of these minute protrusions, the contact area between the cooling material 630 and the aerosol passing through the cooling section 600 is increased. As a result, the cooling effect of the cooling material 630 is improved.

[0100] In one embodiment, the volume ratio of the bead-shaped cooling material 630 to the total volume of the cooling section 600 can be 30% to 35%. Furthermore, the diameter of the bead-shaped cooling material 630 can be approximately 3 mm to 5 mm, and its weight can be approximately 0.3 to 1.0 g.

[0101] On the one hand, at least one wrapping paper 640 can be used to package the first filter element 610, the second filter element 620, and the cooling substance 630 included in the cooling section 600.

[0102] Figures 7a to 7b This is a schematic diagram illustrating a sheet-like cooling material according to one embodiment.

[0103] The cooling substance 710 containing sucrose can be in the form of a sheet.

[0104] In one embodiment, the cooling material 710 may be a porous paper sheet. The porous paper may be a material with elastic resilience and flexibility; for example, the porous paper may be made from cellulose-based materials such as birch or bamboo used to make packaging paper.

[0105] When the cooling substance 710 is formed from porous paper, it can be coated with a coating consisting of sucrose (e.g., sucrose powder), distilled water, and starch syrup. The starch syrup contained in the coating acts to adjust the viscosity and inhibit the precipitation of sugar / glucose crystals.

[0106] On the one hand, the materials included in the coating are not limited to the above-described embodiments, and other substances may be added to improve the efficiency of the coating and drying of the cooling substance 710.

[0107] In one embodiment, the concentration of sucrose (e.g., sucrose powder) may be between 30% wt and 70% wt relative to the overall concentration of the coating applied to the porous paper, and the weight of starch syrup may be less than 40% relative to the overall weight of the coating, but is not limited thereto.

[0108] In another embodiment, the cooling material 710 may be an edible film.

[0109] Edible films can contain biodegradable film materials. For example, starch, cellulose, and their derivatives such as pectin, alginate, carrageenan, and chitosan can be used as biodegradable film materials. Additionally, pullullan, which has excellent coating and film-forming capabilities, can be added to edible films.

[0110] An edible film-like cooling substance 710 can be formed by mixing the above-mentioned biodegradable membrane material with sucrose.

[0111] In yet another embodiment, the sheet-like cooling material 710 may have the same viscosity as wax. To obtain the same viscosity as wax, the cooling material 710 may consist of sucrose, an acidic solution, and distilled water. The acidic solution may be lemon juice, vinegar, etc.

[0112] Reference Figure 7a The sheet-like cooling material 710 can be wound around the cooling material 720. When the wound cooling material 720 is located inside the cooling section 700, the wound cooling material 720 can be located inside the cooling section 700 so that the airflow (e.g., aerosol) passes through along the length direction of the cooling section 700. That is, the wound cooling material 720 can be located inside the cooling section 700 with its length direction parallel to the length direction of the cooling section 700.

[0113] exist Figure 7a In the cooling section 700, since multiple coiled cooling materials 720 are located in the cooling section 700, a honeycomb-shaped airflow path may be formed inside the cooling section 700.

[0114] Additionally, refer to Figure 7b The sheet-like cooling material 710 can be arranged in various patterns in the cooling section 700 so that airflow can pass through along the length of the cooling section 700. For example, cooling material 731 rolled into an irregular pattern, vortex-shaped cooling material 732, or concentric circle-shaped cooling material 733 can be located inside the cooling section 700.

[0115] Figures 8a to 8b This is a schematic diagram illustrating a block-shaped cooling material according to one embodiment.

[0116] The cooling substance containing sucrose can be in block form. In one embodiment, the block cooling substance can be produced by pouring syrup or powdered sucrose into a mold and hardening it.

[0117] Reference Figure 8a The block cooling material can be cylindrical, hollow tubular, or honeycomb-like in shape with multiple pores penetrating its interior. However, the shape of the block cooling material is not limited to these.

[0118] Reference Figure 8b At least one channel may be formed on the outer surface of the block-shaped cooling material. The at least one channel formed on the outer surface of the cooling material may be formed in the length direction of the cooling material so that airflow can pass through in the length direction of the cooling material.

[0119] In one embodiment, at least one channel formed on the outer surface of the cooling material can be a regular or irregular pattern, such as a straight line, curve, spiral, or serrated line. Additionally, protrusions or grooves in a spiral pattern can be formed on the outer surface of the cooling material to serve as channels for airflow.

[0120] Figure 9 This is a diagram illustrating the cooling effect produced by using sucrose as a cooling substance according to an embodiment.

[0121] Reference Figure 9 Cigarettes 910 to 970 consist of a tobacco stick, a tubular section, a cooling section, and a mouthpiece.

[0122] During the heating of the tobacco sticks in cigarettes 910 to 970, air flows into the interior of cigarettes 910 to 970 from the outside whenever the user bites down on and puffs the mouthpiece of cigarettes 910 to 970. Aerosols are generated as the air flows in from the outside through the heated tobacco stick.

[0123] Table 1 below shows the results of measuring the aerosol temperature using cigarettes 910 to 970 according to the first to seventh schemes, wherein the aerosol is generated from the tobacco stick and reaches the upstream end of the mouthpiece after passing through the cooling section. That is, the degree to which the aerosol is cooled when passing through the cooling section in each of the first to seventh schemes can be confirmed by Table 1 below.

[0124] For the measurements in Table 1 below, the aspiration volume was set to 55 ml, the aspiration time to 2 seconds, the aspiration cycle to 20 seconds, and the number of aspirations to 12. In Table 1, the highest temperature refers to the average of the highest temperatures within each aspiration cycle, and the average temperature refers to the average of the average temperatures within each aspiration cycle.

[0125] [Table 1]

[0126]

[0127] In the following text, the tubular part and the cooling part according to the first to seventh embodiments are hollow tubular structures.

[0128] In the first embodiment, the tubular portion of cigarette 910 is made of CA (Cellulose Acetate), and the cooling portion is made of PLA (Polylactic Acid) fabric. The results of measuring the aerosol temperature at the measurement location using cigarette 910 of the first embodiment show a maximum temperature of 79.2°C and an average temperature of 65.8°C.

[0129] In the second embodiment, the tubular portion of cigarette 920 is CA, and the cooling portion is also CA. The results of measuring the aerosol temperature at the measurement location using cigarette 920 of the second embodiment show a maximum temperature of 68.8°C and an average temperature of 57.7°C.

[0130] In the third embodiment, the tubular portion of cigarette 930 is a plate-shaped leaf, and the cooling portion is CA. The results of measuring the aerosol temperature at the measurement location using cigarette 930 in the third embodiment show a maximum temperature of 86.8℃ and an average temperature of 69.0℃.

[0131] In the fourth embodiment, the tubular portion of cigarette 940 is paper, and the cooling portion is CA. The results of measuring the aerosol temperature at the measurement location using cigarette 940 in the fourth embodiment show a maximum temperature of 69.5°C and an average temperature of 55.7°C.

[0132] In the fifth embodiment, the tubular portion of cigarette 950 is CA, and the cooling portion is a plate-shaped leaf. The results of measuring the aerosol temperature at the measurement location using cigarette 950 in the fifth embodiment are as follows: the highest temperature is 77.3℃, and the average temperature is 61.8℃.

[0133] In the sixth embodiment, the tubular portion of cigarette 960 is CA, and the cooling portion is paper. The results of measuring the aerosol temperature at the measurement location using cigarette 960 of the sixth embodiment show a maximum temperature of 85.7°C and an average temperature of 72.7°C.

[0134] In the seventh embodiment, the tubular portion of cigarette 970 is CA, and the cooling portion is sucrose. The results of measuring the aerosol temperature at the measurement location using cigarette 970 of the seventh embodiment show a maximum temperature of 47.3°C and an average temperature of 42.6°C.

[0135] That is, using the cigarettes 910 to 970 according to the first to seventh schemes to measure the aerosol temperature at the upstream end of the nozzle, the highest and average temperatures measured were lowest in the seventh scheme where the cooling substance in the cooling section is sucrose.

[0136] The sucrose contained in the cooling section undergoes caramelization when its temperature reaches its melting point or higher. During this process, the sucrose effectively cools the heated aerosol by absorbing heat from the surrounding environment. Therefore, the user can inhale the aerosol cooled to a suitable temperature.

[0137] Those skilled in the art related to this embodiment should understand that modifications can be made without departing from the essential characteristics of the described content. Therefore, the disclosed methods should not be understood as limiting but as illustrative. The scope of the invention is not embodied in the foregoing description but in the claims, and all distinctions within the equivalent scope should be interpreted as included within the invention.
