Description

The present disclosure relates to aerosol products and aerosol generating devices.

Generally, tobacco refers to a perennial plant of the Solanaceae family of dicotyledonous plants, but in recent times it has come to refer to a product made for smoking, with tobacco leaves wrapped in rolling paper and a filter on one side. There are thousands of varieties of such cigarettes around the world, and they are sold in a variety of patterns and shapes.

Among these, in the case of combustible tobacco products that are lit and smoked, such as cigarettes, cigars, and pipe tobacco, the smoke contains not only aerosols that contain nicotine, but also large amounts of other components such as tar, nitroamines, hydrocarbons, and carbon monoxide.

As an alternative to these shortcomings of combustible cigarettes, a method in which aerosol is generated by heating an aerosol-generating substance in a cigarette, rather than by burning a cigarette, is widely used and demand for this method is increasing. As a result, research into heated cigarettes and heated aerosol generating devices is being actively conducted.

Specifically, aerosol generators have a similar form to conventional combustible cigarettes, and generate mainstream smoke containing aerosols by heating the aerosol-generating material in the heated cigarettes using a heater, ultrasonic vibration, or other methods. This has the advantage of minimizing emissions of substances such as tar while fulfilling the smoker's desire to smoke, creating a new market to replace conventional combustible cigarettes.

However, when a heated cigarette is heated by an aerosol generating device, high-temperature mainstream smoke is generated inside the cigarette, and this high-temperature aerosol can be transmitted to the user. The high-temperature mainstream smoke can cause inconvenience to the user or cause burns. Alternatively, the heated cigarette may not be heated evenly, preventing the aerosol from moving smoothly inside the cigarette.

To solve the above problems, the objective of the present disclosure is to provide an aerosol product that can prevent the user from experiencing inconvenience or being burned.

Another object of the present disclosure is to provide an aerosol product that can uniformly heat the tobacco medium portion to form a rich aerosol.

According to one embodiment, an aerosol product can be provided that includes a tobacco medium portion, a filter portion spaced apart from the tobacco medium portion, a cooling portion disposed between the tobacco medium portion and the filter portion, and a heat transfer portion surrounding at least a portion of the cooling portion.

As described above, the aerosol product according to one aspect of the present disclosure can prevent the user from experiencing inconvenience or being burned by high-temperature mainstream smoke.

In addition, the tobacco medium can be heated uniformly to form a rich aerosol.

The aerosol product according to the first embodiment of the present disclosure is described below.

Figure 1 is a schematic exploded perspective view of an aerosol product according to a first embodiment of the present disclosure, and Figure 2 is a schematic perspective view of an aerosol product according to a first embodiment of the present disclosure. Figure 3 is an enlarged view of the inside of region A in Figure 2, and Figure 4 is a cross-sectional view of an aerosol product according to a first embodiment of the present disclosure.

Referring to Figs. 1 to 4, an aerosol product (100) according to one embodiment of the present disclosure may include a tobacco medium section (110), a cooling section (130), a filter section (150), and a wrapper (170). Here, a person having ordinary skill in the art related to this embodiment may understand that in addition to the components illustrated in Figs. 1 to 4, other general-purpose components may be further included in the aerosol product (100).

The aerosol product (100) according to this embodiment can be inserted into an aerosol generating device (300, see FIGS. 22 and 23) described below and heated. When the aerosol product (100) is heated, mainstream smoke can be delivered to the user. The mainstream smoke can be an airflow flowing from upstream to downstream inside the aerosol product (100). Here, the upstream can refer to the tobacco medium part (110) side, and the downstream can refer to the filter part (150) side. The user of the aerosol product (100) can inhale the mainstream smoke through the downstream end of the aerosol product (100).

The aerosol product (100) may have a cylindrical shape. In this case, the diameter of the aerosol product (100) may be 4.7 mm to 9.9 mm. The tobacco medium section (110), the cooling section (130) and the filter section (150) may also be cylindrical with a diameter of 4.7 mm to 9.9 mm.

The aerosol product (100) may also have a length of 31 mm to 60 mm. The length of the tobacco medium portion (110) may be 17 mm to 30 mm. The length of the cooling portion (130) may be 4 mm to 10 mm, and the length of the filter portion (150) may be 10 mm to 20 mm.

The values for the shape, diameter, and length of the aerosol product (100) and components are shown as examples, but are not necessarily limited thereto. The shape and values of the aerosol product (100) may be modified to the extent that would be acceptable to one skilled in the art.

The tobacco medium portion (110) is located upstream of the aerosol producing product (100) and may contain a tobacco medium for generating an aerosol. The tobacco medium of the tobacco medium portion (110) contains nicotine, allowing mainstream smokers to experience the taste and aroma characteristic of cigarettes.

When the aerosol product (100) according to this embodiment is heated by the aerosol generating device (300, see FIG. 23) described below, and the aerosol generated by the aerosol generating device (300) is flowed into the aerosol product (100), nicotine can be adsorbed on the aerosol surface and delivered to the user as the aerosol passes through the tobacco medium portion (110).

In this case, the nicotine contained in the tobacco medium may be one or more of free base nicotine and nicotine salt, and the nicotine may be naturally occurring nicotine or synthetic nicotine.

Nicotine salts can be formed by adding a suitable acid, including an organic acid or an inorganic acid, to nicotine. The acid for forming the nicotine salt can be appropriately selected taking into consideration the rate of nicotine absorption in the blood, the heating temperature of the heater, the flavor or taste, solubility, and the like. For example, the acid for forming the nicotine salt can be, but is not limited to, a single acid selected from the group consisting of benzoic acid, lactic acid, salicylic acid, lauric acid, sorbic acid, levulinic acid, pyruvic acid, formic acid, acetic acid, propionic acid, butyric acid, valeric acid, caproic acid, caprylic acid, capric acid, citric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, phenylacetic acid, tartaric acid, succinic acid, fumaric acid, gluconic acid, saccharic acid, malonic acid, or malic acid, or a mixture of two or more acids selected from the group.

Meanwhile, the tobacco medium of the tobacco medium portion (110) can be prepared in various forms. For example, the tobacco medium can be prepared in a sheet or a strand. The tobacco medium can also be prepared in the form of shredded tobacco, in which the tobacco sheet is finely cut. The tobacco medium can also be prepared in the form of granules containing tobacco.

The tobacco medium portion (110) may have a cylindrical shape. However, the shape of the tobacco medium portion (110) is not necessarily limited to this, and may have a bar shape having a cross section of various shapes.

In this case, the tobacco medium portion (110) can be produced by folding a tobacco sheet so that it is wrinkled, into a cylindrical shape, or by forming tobacco strands, cut tobacco, or tobacco granules into a cylindrical shape.

When the tobacco medium portion (110) is composed of a plurality of tobacco strands obtained by shredding a tobacco sheet, the tobacco medium portion (110) may be formed by combining a plurality of tobacco strands in the same direction (parallel) or randomly. Specifically, the tobacco medium portion (110) may be formed by combining a plurality of tobacco strands to form a plurality of longitudinal channels through which the aerosol can pass. In this case, the longitudinal channels may be uniform or non-uniform depending on the size and arrangement of the tobacco strands.

The tobacco medium portion (110) may further include an aerosol generating material to increase the amount of atomization. For example, the aerosol generating material may include, but is not limited to, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol.

The tobacco medium portion (110) may further include a flavoring substance to add flavor to the aerosol. For example, the tobacco medium portion (110) may contain other additives such as flavoring agents, humectants, and/or organic acids. In addition, a flavoring liquid such as menthol or a humectant may be added to the tobacco medium portion (110) by being sprayed onto the tobacco medium portion (110).

In this case, the flavoring agent may include licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, mint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, salvia, spearmint, ginger, coriander, or coffee. The humectant may include glycerin or propylene glycol.

Meanwhile, in this embodiment, the tobacco medium portion (110) may be composed of at least one segment. For example, the tobacco medium portion (110) may be composed of one segment or two segments. Specifically, the tobacco medium portion (110) according to this embodiment illustrated in FIG. 4 may be composed of one segment. Also, as illustrated in FIG. 10 and FIG. 11, the tobacco medium portion (110) may be composed of two segments.

Referring to FIG. 4, the tobacco medium portion (110) of this embodiment may consist of one segment. The segment of the tobacco medium portion (110) may be filled with tobacco medium. That is, in this embodiment, the tobacco medium portion (110) may consist of one segment filled with tobacco medium.

In this case, the segment can be prepared by folding a tobacco sheet into a cylindrical shape as described above, or by forming tobacco strands, cut tobacco, or tobacco granules into a cylindrical shape. The segment can further include an aerosol generating material and/or a flavoring material that can increase the amount of atomization.

The segment of the tobacco medium portion (110) may also be heated by coupling it to a heating portion (370, see FIG. 22) of the aerosol generating device (300) that heats the aerosol product (100). In FIG. 22, the heating portion (370) may be inserted inside the aerosol product (100) to heat the tobacco medium portion (110).

On the other hand, in the variant illustrated in Figures 10 and 11, the tobacco medium portion (110) may consist of two segments, one of which may contain the tobacco medium and the other of which may not contain the tobacco medium.

Referring to Figures 10 and 11, the tobacco medium portion (110) may include a first tobacco segment (111) and a second tobacco segment (113). The first tobacco segment (111) is a segment filled with tobacco medium and may be the same as the segment of the tobacco medium portion (110) of Figure 4 described above.

The second tobacco segment (113) is located at the upstream end of the aerosol product (100) and can prevent the first tobacco segment (111) containing the tobacco medium from escaping to the outside of the aerosol product (100). That is, the tobacco medium portion (110) of this modified example can be arranged in the order of the second tobacco segment (113) and the first tobacco segment (111) from the upstream side.

The second tobacco segment (113) can prevent impurities from flowing into the first tobacco segment (111) from the outside and can prevent the aerosol liquefied during smoking from flowing into the aerosol generating device (300, see Figure 22 or Figure 23).

In addition, when the aerosol product (100) is inserted into the aerosol generating device (300), the second tobacco segment (113) can support the aerosol product (100) so that the aerosol product (100) is fixed to the aerosol generating device (300).

The second tobacco segment (113) may be a cellulose acetate filter. For example, the second tobacco segment (113) may be made of cellulose acetate tow to which a plasticizer such as triacetin has been added. The cellulose acetate tow may also include an aerosol-generating substance.

The aerosol generating substance contained in the second tobacco segment (113) may exclude nicotine. For example, the second tobacco segment (113) may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. However, the aerosol generating substance contained in the second tobacco segment (113) is not necessarily limited thereto. For example, the second tobacco segment (113) may include a substance in which glycerin and propylene glycol are mixed in a ratio of approximately 8:2. However, the mixture ratio is not limited to the above-mentioned ratio.

In addition, the second tobacco segment (113) may contain other additives such as flavorings, humectants, and/or organic acids. However, the material and type of the second tobacco segment (113) are not necessarily limited thereto and may be varied within the scope of what can be adopted by those skilled in the art.

The second tobacco segment (113) may have a through hole formed therein through which the aerosol flows from the outside to form mainstream smoke inside the aerosol product (100). The through hole formed in the second tobacco segment (113) may have a circular or Y-shaped cross section. However, the cross-sectional shape of the through hole is not necessarily limited thereto and may have various cross-sectional shapes.

On the other hand, if the second tobacco segment (113) comprises a crimped sheet impregnated with an aerosol-generating substance, no holes may be formed in the second tobacco segment (113).

When a portion of the aerosol product (100) is inserted into the aerosol generating device (300, see FIG. 23), the aerosol generated in the aerosol generating device (300) flows into the aerosol product (100) through the second tobacco segment (113), and the aerosol forms mainstream smoke inside the aerosol product (100) and can be delivered to the user. Also, the aerosol generated inside the second tobacco segment (113) containing the aerosol generating substance can form mainstream smoke and be delivered to the user.

In this case, the tobacco medium section (110) may be heated by the heating section (390) of the aerosol generating device (300) being disposed around the tobacco medium section (110). The heat transfer section (190) may surround the first cooling segment (131) of the cooling section (130), or may surround not only the first cooling segment (131) but also at least a portion of the second cooling segment (133). A detailed description of this will be given later.

Referring again to FIG. 1 to FIG. 4, in this embodiment, the filter portion (150) may be located at the downstream end away from the tobacco medium portion (110). The filter portion (150) may filter at least one of the substances contained in mainstream smoke.

The filter portion (150) may be a cellulose acetate filter, which may be made by adding a plasticizer such as triacetin to cellulose acetate tow. However, the material and type of the filter portion (150) are not necessarily limited thereto, and may be changed within the range that can be adopted by a person skilled in the art.

The filter portion (150) may be cylindrical. However, the shape of the filter portion (150) is not necessarily limited to this and may have various shapes corresponding to the shape of the tobacco medium portion (110).

The filter portion (150) may be fabricated to emit a flavor. For example, a flavoring liquid may be sprayed onto the filter portion (150), or separate fibers onto which the flavoring liquid is applied may be included inside the filter portion (150).

Alternatively, the filter portion (150) may include at least one capsule (not shown). The capsule may generate a flavor or may generate an aerosol. For example, the capsule may have a structure in which a liquid containing a flavoring is enveloped in a membrane. In this case, the capsule may have a spherical or cylindrical shape, but the shape of the capsule is not necessarily limited thereto.

In the aerosol product (100) according to this embodiment, the cooling section (130) is disposed between the tobacco medium section (110) and the filter section (150) to cool the high-temperature aerosol passing through the inside. The high-temperature aerosol emitted from the tobacco medium section (110) is cooled as it moves through the cooling section (130), and the cooled aerosol can be delivered to the user through the filter section (150). This prevents the high-temperature aerosol from being directly delivered to the user.

In this embodiment, the cooling section (130) may be composed of a first cooling segment (131) and a second cooling segment (133). That is, the cooling section (130) may be composed of two segments. However, the cooling section (130) is not necessarily limited to this and may be composed of two or more segments.

The first cooling segment (131) and the second cooling segment (133) may be arranged adjacent to the tobacco medium section (110) in this order. Specifically, the first cooling segment (131) may be arranged in contact with the tobacco medium section (110), and the second cooling segment (133) may be arranged between the first cooling segment (131) and the filter section (150). That is, in this embodiment, the tobacco medium section (110), the first cooling segment (131), the second cooling segment (133), and the filter section (150) may be arranged in this order from upstream.

The first cooling segment (131) not only cools the aerosol coming out of the tobacco medium section (110), but also prevents the tobacco medium in the tobacco medium section (110) from escaping to the second cooling segment (133). For example, when a heating section (370, see FIG. 22) for heating the aerosol product (100) is inserted into the tobacco medium section (110), the tobacco medium in the tobacco medium section (110) may detach and move to the second cooling segment (133). By disposing the first cooling segment (131) between the tobacco medium section (110) and the second cooling segment (133), the tobacco medium in the tobacco medium section (110) can be prevented from escaping to the second cooling segment (133).

The first cooling segment (131) may be made by adding a plasticizer, such as triacetin, to cellulose acetate tow. The cellulose acetate tow may also contain an aerosol-generating substance.

The first cooling segment (131) may contain at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. However, the aerosol generating material contained in the first cooling segment (131) is not necessarily limited thereto. For example, the first cooling segment (131) may contain a material in which glycerin and propylene glycol are mixed in a ratio of approximately 8:2. However, the mixture ratio is not limited to the above-mentioned ratio.

In addition, the first cooling segment (131) may contain other additives such as flavorings, humectants, and/or organic acids. However, the material and type of the first cooling segment (131) are not necessarily limited thereto and may be changed within the scope of what can be adopted by a person skilled in the art.

The first cooling segment (131) may have a through hole through which the aerosol flows from the tobacco medium portion (110) to form a main flow inside the aerosol product (100). The through hole formed in the first cooling segment (131) may have a circular or Y-shaped cross section. However, the cross-sectional shape of the through hole is not necessarily limited thereto and may have various cross-sectional shapes.

The second cooling segment (133) is disposed between the first cooling segment (131) and the filter section (150) and can further cool the aerosol that has passed through the first cooling segment (131).

The second cooling segment (133) may have a tubular shape through which the aerosol can pass. Specifically, the second cooling segment (133) may have a through hole (T) formed therein. The through hole (T) is a space formed in the center of the second cooling segment (133), through which the aerosol can move from the tobacco medium section (110) to the filter section (150). In this embodiment, the diameter of the through hole (T) of the second cooling segment (133) may be larger than the through hole of the first cooling segment (131). However, the diameter of the through hole (T) of the second cooling segment (133) is not necessarily limited thereto, and the diameter of the through hole (T) of the second cooling segment (133) may be the same as or smaller than the through hole of the first cooling segment (131).

The high-temperature aerosol flowing into the inlet of the second cooling segment (133) can be cooled as it passes through the through hole (T) of the second cooling segment (133). During the aerosol cooling process, some of the heat contained in the aerosol can be discharged to the outside through the main body of the second cooling segment (133). At this time, a separate member containing PLA (polylactic acid) can be placed inside the through hole (T) of the second cooling segment (133). For example, the inside of the through hole (T) can be at least partially filled with PLA.

The main body of the second cooling segment (133) may be made by adding a plasticizer such as triacetin to cellulose acetate tow. Alternatively, the main body of the second cooling segment (133) may be made of a paper insert composed of multiple papers. For example, the main body may be a paper insert composed of an outer paper, a middle paper, and an inner paper, but is not necessarily limited to this, and may be a single paper. In this case, a cooling substance may be coated on the inside of the paper insert, and a cooling film may be attached. Here, the cooling substance or cooling film may include various substances having high thermal efficiency. However, the material and type of the main body of the second cooling segment (133) are not necessarily limited to this and may be changed within the range that can be adopted by a person skilled in the art.

When the main body of the second cooling segment (133) is made of cellulose acetate tow, the mono denier of the filaments constituting the cellulose acetate tow may be 3 to 20. Preferably, the mono denier of the filaments of the main body may be 9 to 12.

The cross section of the filament constituting the main body of the second cooling segment (133) may be Y-shaped. Here, the filament may refer to a long fiber connected in a single strand that constitutes the cellulose acetate tow.

Meanwhile, the main body of the second cooling segment (133) may contain other additives such as flavoring agents, humectants, and/or organic acids. In this case, the flavoring agents may include licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, mint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, salvia, spearmint, ginger, coriander, or coffee. The humectant may include glycerin or propylene glycol.

The body of the second cooling segment (133) may have a donut-shaped cross section due to the through hole (T). In this case, the inner diameter of the body may be 2 mm or more. Preferably, the inner diameter of the body may be 3.8 to 4.2 mm.

At this time, a plurality of openings (160) may be formed in the body of the second cooling segment (133) so that outside air can flow in and internal air can flow out. The plurality of openings (160) may be formed spaced apart from one another in the circumferential direction of the body.

In this embodiment, a plurality of openings (160) may be disposed on the inlet side of the second cooling segment (133), i.e., adjacent to the first cooling segment (131). The aerosol passing through the second cooling segment (133) can be further cooled by the outside air flowing in through the plurality of openings (160). This allows the aerosol flowing into the filter portion (150) to be cooled again, thereby preventing the high-temperature aerosol from being inhaled into the user's mouth.

In this embodiment, the multiple openings (160) are described as being disposed on the inlet side of the second cooling segment (133), but the location of the multiple openings (160) is not necessarily limited thereto, and the multiple openings (160) may be disposed at other locations on the second cooling segment (133), for example, on the outlet side of the second cooling segment (133) or in the central region of the second cooling segment (133).

According to this embodiment, the heat transfer unit (190) may be disposed to surround at least a portion of the cooling unit (130). The heat transfer unit (190) may heat or cool the aerosol inside the aerosol product (100). A specific process in which the heat transfer unit (190) heats or cools the aerosol will be described later with reference to FIGS. 5 and 6.

The heat transfer section (190) surrounds the outer peripheral surface of the cooling section (130), but may surround only a portion of the cooling section (130) along the longitudinal direction of the cooling section (130) or may surround the entire cooling section (130).

Specifically, as shown in FIG. 4, in this embodiment, the heat transfer section (190) can surround the entire outer circumferential surface of the first cooling segment (131) of the cooling section (130).

Alternatively, in the variation of FIG. 7, the heat transfer portion (190) can surround only a portion of the first cooling segment (131).

Alternatively, in the modified example of FIG. 8, the heat transfer section (190) can surround the entire first cooling segment (131) and only a portion of the second cooling segment (133). In this case, the heat transfer section (190) can be positioned up to just before the position where the opening (160) is formed in the second cooling segment (133) so as not to cover the opening (160).

Alternatively, in the modified example of FIG. 9, the heat transfer section (190) can surround the entire first cooling segment (131) and the entire second cooling segment (133). That is, the heat transfer section (190) can be arranged to surround the entire cooling section (130). In this case, the heat transfer section (190) can have an opening formed at a position corresponding to the opening (160) of the second cooling segment (133).

In this embodiment, the heat transfer section (190) may extend from the inlet of the cooling section (130) that contacts the tobacco medium section (110). As shown in FIG. 4, the heat transfer section (190) may be disposed at the position where the tobacco medium section (110) and the cooling section (130) contact each other, i.e., from the inlet of the cooling section (130) to surround the cooling section (130). As a result, the heat transfer section (190) can keep the downstream side of the tobacco medium section (110) warm so that it is heated to the same temperature as the other sections of the tobacco medium section (110) while the tobacco medium section (110) is heated by the heating section (370). In addition, the heat transfer section (190) can further cool the aerosol moving inside the cooling section (130). A specific process for this will be described later.

Below, with reference to Figures 5 and 6, the process by which the heat transfer section (190) heats or cools the aerosol in the aerosol product (100) according to this embodiment will be described.

Figure 5 is a diagram illustrating the process in which a heating unit is inserted into an aerosol product according to the first embodiment of the present disclosure to heat the tobacco medium portion, and Figure 6 is a diagram illustrating the process in which a heating unit is inserted into a conventional aerosol product to heat the tobacco medium portion.

The heat transfer unit (190) of this embodiment can keep the aerosol warm while heating the tobacco medium unit (110) before the user inhales the mainstream smoke, and can cool the aerosol while the user inhales the mainstream smoke.

The process in which a user inhales mainstream smoke using the aerosol product (100) of this embodiment can be divided into a process in which the heating section (370) of the aerosol generating device (300, see FIG. 22) inserted into the tobacco medium section (110) first heats the tobacco medium section (110) to generate an aerosol, and a process in which the user then inhales mainstream smoke through the mouth when the tobacco medium section (110) reaches a predetermined temperature and an aerosol is generated.

Referring to FIG. 5, while the heating section (370) first heats the tobacco medium section (110), the heat transfer section (190) can keep the downstream side (P) of the tobacco medium section (110) adjacent to the cooling section (130) warm. This allows the heat transfer section (190) to heat the entire section of the tobacco medium section (110) at a uniform temperature while the initial tobacco medium section (110) is being heated.

The heat transfer section (190) is in the form of a metal foil and can prevent heat generated from the heating section (370) on the downstream side (P) of the tobacco medium section (110) from being released to the outside through the main body of the cooling section (130). By preventing heat from being released to the outside by the heat transfer section (190), it is possible to prevent the temperature of the downstream side (P) of the tobacco medium section (110) from becoming too low, unlike in the past.

Figure 6 illustrates the process in which a conventional aerosol product (100) is heated by a heating section (370). First, while the heating section (370) heats the tobacco medium section (110), the heat inside the downstream side (P) of the tobacco medium section (110) can be released through the adjacent cooling section (130) (see Figure 6 (A)). As a result, the temperature of the downstream side (P) of the tobacco medium section (110) becomes lower than the temperature of the other sections (M) of the tobacco medium section (110) (see Figure 6 (B)).

The heating section (370) is in the form of an electric resistance heater (H) surrounded by a ceramic material (C), and since the high temperature of the heating section (370) may melt the cooling section (130), the end of the heating section (370) cannot be inserted close to the cooling section (130). That is, the end of the heating section (370) cannot be inserted to the very end of the tobacco medium section (110). As such, since the end of the heating section (370) cannot be inserted to the very end of the tobacco medium section (110), the downstream side (P) of the tobacco medium section (110) is heated less than the other sections (M), and the heat inside the downstream side (P) is released through the adjacent cooling section (130), so that the temperature of the downstream side (P) of the tobacco medium section (110) may be lower than the temperature of the other sections (M).

When the temperature of the downstream side (P) of the tobacco medium section (110) is low, the aerosol generated in other sections (M) of the tobacco medium section (110) is liquefied on the downstream side (P) of the tobacco medium section (110) where the temperature is low, and this impedes the flow of the aerosol on the downstream side (P) of the tobacco medium section (110). In other words, the aerosol generated in the tobacco medium section (110) cannot flow smoothly to the cooling section (130).

Therefore, in this embodiment, the heat transfer section (190) keeps the downstream side of the tobacco medium section (110) warm while the tobacco medium section (110) is first heated, so that the aerosol generated in the tobacco medium section (110) can flow smoothly to the cooling section (130) without being stagnant on the downstream side of the tobacco medium section (110).

Meanwhile, when the tobacco medium section (110) reaches a predetermined temperature and aerosol is generated, and the user inhales mainstream smoke through the mouth, the heat transfer section (190) can further cool the high-temperature aerosol moving inside the cooling section (130). When the high-temperature aerosol is cooled while passing through the inside of the cooling section (130), the heat transfer section (190) surrounding the cooling section (130) dissipates heat to the outside of the cooling section (130), thereby further cooling the high-temperature aerosol. This can prevent the high-temperature aerosol from being directly transferred to the user.

In this case, the heat transfer part (190) may be in the form of a metal foil. That is, the heat transfer part (190) may surround the cooling part (130) in the form of a thin metal plate. The metal heat transfer part (190) is disposed on the outer periphery of the cooling part (130) adjacent to the tobacco medium part (110), so that the aerosol can be kept warm or cooled during smoking.

The heat transfer part (190) may include a metal material. For example, the heat transfer part (190) may include at least one of aluminum, copper, ferrite, and martensite. Preferably, the heat transfer part (190) may be in the form of a metal foil including aluminum. However, the heat transfer part (190) is not necessarily limited thereto, and various materials having high thermal conductivity may be applied.

In this embodiment, the heat transfer unit (190) may be disposed around the outer periphery of the cooling unit (130) in the form of a metal plate (see FIG. 1). Alternatively, as shown in the modified examples of FIGS. 12 to 14, the heat transfer unit (190) may be disposed around the outer periphery of the cooling unit (130) in the form of multiple metal bands. The multiple metal bands constituting the heat transfer unit (190) may be disposed at a distance from each other.

Referring to FIG. 12, the heat transfer unit (190) may surround the outer periphery of the first cooling segment (131) of the cooling unit (130) in the form of metal bands spaced apart from each other. In this case, the heat transfer unit (190) in the form of multiple metal bands may be arranged parallel to the extension direction of the cooling unit (130). That is, the multiple metal bands may be arranged parallel to the cooling unit (130).

Referring to FIG. 13, the heat transfer section (190) is arranged in the form of multiple metal bands, which may be arranged diagonally with respect to the extension direction of the cooling section (130). That is, unlike FIG. 12 described above, the multiple metal bands may be arranged not parallel to the extension direction of the cooling section (130). Specifically, the multiple metal bands may be arranged in a spiral shape wrapped around the outer circumferential surface of the cooling section (130).

Referring to FIG. 14, the heat transfer section (190) is arranged in the form of multiple metal bands and is arranged parallel to the extension direction of the cooling section (130), although the metal bands may be arranged in a serpentine form.

Referring again to FIG. 4, the aerosol product (100) according to this embodiment can be wrapped by a wrapper 170. The wrapper (170) can surround the tobacco medium section (110), the cooling section (130) and the filter section (150) arranged in a row. In this way, when the wrapper (170) surrounds the tobacco medium section (110), the cooling section (130) and the filter section (150), the aerosol product (100) can maintain its inherent cylindrical shape.

The wrapper (170) can surround the entire outer periphery of the tobacco medium section (110), the cooling section (130) and the filter section (150).

Each of the tobacco medium portion (110), cooling portion (130) and filter portion (150) constituting the aerosol product (100) of this embodiment may be individually wrapped in a separate wrapper (not shown). When the tobacco medium portion (110) includes multiple segments, each of the multiple segments may be wrapped in a separate wrapper, or the multiple segments may be wrapped in a single wrapper. In this manner, when the tobacco medium portion (110), cooling portion (130) and filter portion (150) are individually wrapped, the individually wrapped tobacco medium portion (110), cooling portion (130) and filter portion (150) may be repackaged in a wrapper (170).

The wrapper (170) may have a number of openings (not shown) formed therein to allow outside air to flow into the aerosol product (100) and allow internal air to flow out. The openings may be formed at positions corresponding to the openings (160) of the cooling section (130).

The wrapper (170) may be made of a conventional wrapping paper. For example, the wrapper (170) may be a porous wrapping paper or a non-porous wrapping paper.

The wrapper (170) may include a specific material. Here, the specific material may be silicon, but is not necessarily limited to this. For example, silicon may have properties such as heat resistance, which means that it does not change much with temperature, oxidation resistance, resistance to various chemicals, water repellency, and electrical insulation. However, any material other than silicon that has the above-mentioned properties may be applied to the wrapper (170) without restrictions.

In addition, since the wrapper (170) contains a non-flammable substance, it is possible to prevent the aerosol product (100) of this embodiment from being burned. For example, when the tobacco medium portion (110) is heated by the heating portion (370) of the aerosol generating device (300), the aerosol product (100) may be burned. Specifically, when the temperature of any one of the substances contained in the tobacco medium portion (110) rises above the ignition point, the aerosol product (100) may be burned.

The wrapper (170) can prevent the aerosol generating device (300) from being contaminated by the substance generated by the aerosol product (100) of this embodiment. When smoking, a liquid substance can be generated within the aerosol product (100). For example, a liquid substance such as water can be generated by cooling the aerosol generated by the aerosol product (100) with the outside air.

The wrapper (170) wraps the tobacco medium section (110), the cooling section (130), and the filter section (150), thereby preventing the liquid substance generated in the aerosol product (100) from leaking outside the aerosol product (100). Therefore, the inside of the aerosol generating device (300) can be prevented from being contaminated by the liquid substance generated in the aerosol product (100).

Since the wrapper (170) forms the outermost surface of the aerosol product (100), the shape of the aerosol product (100) can be changed according to the shape of the wrapper (170). For example, the wrapper (170) can be printed with letters, patterns, symbols, images, etc., and the letters, patterns, symbols, images, etc. printed on the wrapper (170) can be changed, so that the aerosol product (100) can provide different visual information from each other.

The following describes the aerosol product according to the second embodiment of the present disclosure and its modified example.

Figure 15 is a cross-sectional view of an aerosol product according to a second embodiment of the present disclosure, Figures 16 to 18 show modified examples of the tobacco medium portion of the aerosol product according to the second embodiment of the present disclosure, and Figure 19 shows a modified example of the filter portion of the aerosol product of Figure 16.

Referring to FIG. 15, the aerosol product according to the second embodiment has the same structure as the aerosol product according to the first embodiment (100) except for the tobacco medium section (110) and the cooling section (130), so a duplicated description of the same components will be omitted.

According to this embodiment, as shown in FIG. 15, the cooling unit (130) may be configured as one segment, unlike the cooling unit (130) of the first embodiment. That is, in the first embodiment described above, the cooling unit (130) is configured as two segments, but in this embodiment, the cooling unit (130) may be configured as one segment.

In this case, the cooling section (130) can be configured with the same shape and material as the second cooling segment (133) of the first embodiment described above.

The cooling section (130) may have a tubular shape through which the aerosol can pass. Specifically, the cooling section (130) may have a through hole (T) formed therein. The through hole (T) is a space formed in the center of the cooling section (130), through which the aerosol can move from the tobacco medium section (110) to the filter section (150).

The high-temperature aerosol that flows into the inlet of the cooling unit (130) can be cooled as it passes through the through hole (T) of the cooling unit (130). During the aerosol cooling process, some of the heat contained in the aerosol can be discharged to the outside through the main body of the cooling unit (130).

The body of the cooling section (130) may be made of cellulose acetate tow with the addition of a plasticizer such as triacetin. Alternatively, the body of the cooling section (130) may be made of a laminated paper made of multiple papers. The body of the cooling section (130) may contain other additives such as flavoring agents, humectants, and/or organic acids.

In this embodiment, the heat transfer section (190) may be arranged to surround the outer circumferential surface of the cooling section (130). As in the first embodiment, the heat transfer section (190) may extend from the inlet of the cooling section (130) adjacent to the tobacco medium section (110). In this case, the heat transfer section (190) may extend up to the front of the opening (160) of the cooling section (130). However, the heat transfer section (190) is not necessarily limited to this, and may be arranged to surround a part or the entirety of the cooling section (130).

Meanwhile, in this embodiment, the tobacco medium part (110) may consist of one segment containing tobacco medium, similar to the first embodiment described above. Here, the tobacco medium part (110) may have the same shape and material as the tobacco medium part (110) of the first embodiment described above.

Figures 16 to 18 show a modified example of the tobacco medium portion (110) of this embodiment, in which the tobacco medium portion (110) can consist of two segments.

Referring to FIG. 16, the tobacco medium part (110) may include a first tobacco segment (111) and a second tobacco segment (113). The first tobacco segment (111) may be made of the same material and shape as the tobacco medium part (110) of the first embodiment described above. For example, the first tobacco segment (111) includes a tobacco medium, which may be made into a sheet or a strand. The tobacco medium may also be made into shredded tobacco, which is a tobacco sheet cut into small pieces. The tobacco medium may also be made into a granular form containing tobacco.

In addition, when the aerosol product (100) is inserted into the aerosol generating device (300), the second tobacco segment (113) can support the aerosol product (100) so that the aerosol product (100) is fixed to the aerosol generating device (300).

The second tobacco segment (113) may be a cellulose acetate filter. For example, the second tobacco segment (113) may be made of cellulose acetate tow to which a plasticizer such as triacetin has been added. The cellulose acetate tow may also include an aerosol-generating substance.

The aerosol generating substance contained in the second tobacco segment (113) may exclude nicotine. For example, the second tobacco segment (113) may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. However, the aerosol generating substance contained in the second tobacco segment (113) is not necessarily limited thereto.

In addition, the second tobacco segment (113) may contain other additives such as flavorings, humectants, and/or organic acids. However, the material and type of the second tobacco segment (113) are not necessarily limited thereto and may be varied within the scope of what can be adopted by those skilled in the art.

The second tobacco segment (113) may have a through hole through which aerosol flows from the outside to form mainstream smoke inside the aerosol product (100). The through hole formed in the second segment (119) may have a circular or Y-shaped cross section. However, the cross-sectional shape of the through hole is not necessarily limited thereto and may have various cross-sectional shapes.

Referring to FIG. 17, the tobacco medium portion (110) may include a first tobacco segment (111) and a third tobacco segment (115). The first tobacco segment (111) may be made of the same material and shape as the first tobacco segment (111) described above. Meanwhile, the third tobacco segment (115) is located in front of the first tobacco segment (111) and may include a crimped sheet impregnated with an aerosol-generating substance.

Referring to FIG. 18, the tobacco medium portion (110) may include a fourth tobacco segment (117) and a fifth tobacco segment (119). The fourth tobacco segment (117) and the fifth tobacco segment (119) may be in the form of a liquid nicotine solution or a nicotine salt impregnated into a crimped sheet.

Figure 19 shows a modified example of the filter section (150) of this embodiment, in which a recess section (180) may be formed downstream of the filter section (150). The recess section (180) has a structure in which the wrapper (170) surrounding the filter section (150) extends further downstream than the filter section (150). That is, in this embodiment, the wrapper (170) extends further outside the filter section (150) than in the aerosol product (100) of the above-mentioned embodiment. Due to the shape of the wrapper (170), the filter section (150) may have a recessed rod shape.

The recessed portion (180) can prevent nicotine traces that occur on the end of the downstream filter portion (150) from being easily exposed to the outside. Therefore, nicotine traces that occur on the filter portion (150) of the aerosol product (100) during smoking or after smoking is completed are not exposed to the outside, which may not spoil the aesthetic appearance.

Below, the process by which the heat transfer section (190) heats or cools the aerosol in the aerosol product (100) according to this embodiment will be described with reference to Figures 20 and 21.

Figure 20 is a diagram explaining the process in which a conventional aerosol product is heated by the heating unit of an aerosol generating device, and Figure 21 is a diagram explaining the process in which an aerosol product according to the second embodiment of the present disclosure is heated by the heating unit of an aerosol generating device,

Referring to FIG. 20, conventionally, the heating unit (370) is arranged to surround the entire tobacco medium unit (110) in order to heat the entire tobacco medium unit (110) uniformly. The heating unit (370) is arranged up to the top of the aerosol generating device (300), which may cause the top of the aerosol generating device (300) to heat up to a high temperature, resulting in burns to the user.

Referring to FIG. 21, the heat transfer section (190) is disposed on the inlet side of the cooling section (130) adjacent to the tobacco medium section (110), and the heating section (390) of the aerosol generating device (300) can be disposed only up to a position spaced a certain distance (G) from the downstream side of the tobacco medium section (110). This prevents the top of the aerosol generating device (300) from being heated to a high temperature by the heating section (390), and prevents a user who comes into contact with the top of the aerosol generating device (300) from being burned.

The following describes an aerosol generating device into which an aerosol product according to one embodiment of the present disclosure is inserted.

Figure 22 is a schematic diagram of an aerosol generating device into which an aerosol product according to the first embodiment of the present disclosure is inserted, and Figure 23 is a modified example of the aerosol generating device of Figure 22.

22 and 23, the aerosol generating device (300) according to this embodiment may include a heating unit (370, 390), a power supply unit (330), a control unit (310), and an aerosol generating unit (350). In addition to the components shown in FIGS. 22 and 23, a person having ordinary skill in the art related to this embodiment may understand that other general-purpose components may be further included in the aerosol generating device (300).

Meanwhile, in FIG. 23, the power supply unit (330), the control unit (310), and the aerosol generating unit (350) are illustrated as being arranged in a line, but the arrangement of the power supply unit (330), the control unit (310), and the aerosol generating unit (350) may be changed as necessary. Also, as in FIG. 22, the aerosol generating unit (350) may be omitted, and the aerosol product (100) may be operated only by being heated by the heating unit (370).

An aerosol product (100) may be inserted into the aerosol generating device (300). The aerosol product (100) may be inserted and fixed into the aerosol generating device (300) by a fixing means. In this embodiment, the tobacco medium portion (110) of the aerosol product (100) may correspond to the fixing means. However, in addition to the tobacco medium portion (110), other fixing means may also be added.

The heating section (370, 390) can heat the aerosol product (100). The heating section (370, 390) is heated by the power supplied from the power supply section (330), thereby allowing the heating section (370, 390) to transfer heat to the aerosol product (100).

The heating units (370, 390) may be electrically resistive heaters. The heating units (370, 390) may include an electrically conductive track, and the heating units (370, 390) may heat the aerosol product (100) by passing an electric current through the electrically conductive track by a power source provided by the power source unit (330).

As another example, the heating unit (370, 390) may be an induction heater. The heating unit (370, 390) may include an electrically conductive coil for inductively heating the aerosol product (100), and the aerosol product (100) may include a susceptor that may be heated by the induction heater.

The power supply unit (330) supplies the power used by the aerosol generating device (300). For example, the power supply unit (330) can supply power to heat the heating units (370, 390) and can supply the power necessary for the control unit (310) to operate. The power supply unit (330) can also supply the power necessary for the display, sensor, motor, etc. of the aerosol generating device (300) to operate.

The control unit (310) controls the overall operation of the aerosol generating device (300). Specifically, the control unit (310) controls the operation of the power supply unit (330) and other components included in the aerosol generating unit (350). The control unit (310) can also check the state of each component of the aerosol generating device (300) to determine whether the aerosol generating device (300) is in an operable state.

The aerosol generating unit (350) can heat the liquid composition to generate an aerosol, and the generated aerosol can be transmitted to the user through the aerosol product (100). In other words, the aerosol generated by the aerosol generating unit (350) can flow into the tobacco medium portion (110) of the aerosol product (100).

The aerosol generating unit (350) may include, but is not limited to, a liquid storage unit, a liquid transfer means, and a heating element. For example, the liquid storage unit, the liquid transfer means, and the heating element may be included in the aerosol generating device (300) as separate modules.

The liquid storage unit can store a liquid composition. For example, the liquid composition can be a liquid containing a tobacco-containing substance, including a volatile tobacco aroma component, or a liquid containing a non-tobacco substance. The liquid storage unit can be made to be removable or can be made to be integral with the aerosol generating device (300).

When the aerosol generating unit (350) according to one embodiment of the present disclosure contains a liquid containing a non-tobacco substance, the liquid composition stored in the liquid storage unit included in the aerosol generating unit (350) may not contain nicotine, and the aerosol generated from the aerosol generating unit (350) may flow into the tobacco medium unit (110) without containing nicotine. In this case, the aerosol that does not contain nicotine passes through the tobacco medium unit (110) and adsorbs nicotine, and the aerosol that has passed through the tobacco medium unit (110) contains nicotine.

The liquid composition contained in the aerosol generating unit (350) may include water, solvent, ethanol, plant extract, fragrance, flavoring agent, or vitamin mixture. The fragrance may include, but is not limited to, menthol, peppermint, spearmint oil, various fruit fragrance ingredients, etc. The flavoring agent may include ingredients that can provide various flavors or tastes to the user. The vitamin mixture may be, but is not limited to, a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E. The liquid composition may also include an aerosol forming agent such as glycerin and propylene glycol.

Although one embodiment of the present disclosure has been described above, a person having ordinary skill in the art may modify and change the present disclosure in various ways by adding, changing, deleting or adding components, without departing from the spirit of the present disclosure as set forth in the claims, and this would also be considered to be within the scope of the rights of the present disclosure.
