[0038] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings so that those skilled in the art can easily implement the present disclosure. The present disclosure can be implemented in many different forms and is not limited to the embodiments described below.

[0039] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0040] Figures 1 to 3 is a diagram showing an example of an aerosol-generating article inserted into an aerosol-generating device according to an embodiment.

[0041] Reference Figure 1 The aerosol generating device 1 includes a battery 11, a controller 12 and a heater 13. Figure 2 as well as Figure 3 The aerosol generating device 1 may further include a vaporizer 14. In addition, an aerosol generating article 2 (eg, a cigarette) may be inserted into the inner space of the aerosol generating device 1.

[0042] Figures 1 to 3 The aerosol generating device 1 may include components related to the embodiments described herein. Therefore, a person skilled in the art of the present disclosure understands that the aerosol generating device 1 includes Figures 1 to 3 Other common components may be included in addition to the components shown.

[0043] Furthermore, although the heater 13 is Figure 2 and Figure 3 Although shown as being included in the aerosol generating device 1 , the heater 3 may be omitted as desired.

[0044] Figure 1 The linear alignment of the battery 11, the controller 12 and the heater 13 is shown. Figure 2 The linear alignment of the battery 11, controller 12, vaporizer 14, and heater 13 is shown. Figure 3 The vaporizer 14 is shown aligned in parallel with the heater 13. However, the internal structure of the aerosol generating device 1 is not limited to Figures 1 to 3 In other words, the alignment of the battery 11 , the controller 12 , the heater 13 , and the vaporizer 14 may be changed according to the design of the aerosol generating device 1 .

[0045] When the aerosol-generating article 2 is inserted into the aerosol-generating device 1, the aerosol-generating device 1 may operate the heater 13 and / or the vaporizer 14 to generate an aerosol. The aerosol generated by the heater 13 and / or the vaporizer 14 may pass through the aerosol-generating article 2 to reach the user.

[0046] Even when the aerosol-generating article 2 is not inserted into the aerosol-generating device 1 , the aerosol-generating device 1 may heat the heater 13 as required.

[0047] The battery 11 can provide power to be used to operate the aerosol generating device 1. For example, the battery 11 can provide power to heat the heater 13 or the vaporizer 14, and can provide power required for the controller 12. In addition, the battery 11 can provide power required for operating a display, a sensor, a motor, etc. installed in the aerosol generating device 1.

[0048] The controller 12 can control the overall operation of the aerosol generating device 1. Specifically, in addition to controlling the operation of the battery 11, the heater 13, and the vaporizer 14, the controller 12 can also control the operation of other components included in the aerosol generating device 1. In addition, the controller 12 can verify the state of each of the components of the aerosol generating device 1 to determine whether the aerosol generating device 1 is in an operable state.

[0049] The controller 12 includes at least one processor. The processor may be implemented as a plurality of logic gate arrays, or may be implemented as a combination of a general-purpose microprocessor and a memory, wherein the memory stores a program that can be executed by the microprocessor. In addition, it is understood by those skilled in the art that the present disclosure belongs that the processor may be implemented with other types of hardware.

[0050] The heater 13 may be heated by the power provided by the battery 11. For example, when the cigarette is inserted into the aerosol generating device 1, the heater 13 may be arranged outside the cigarette. Therefore, the heated heater 13 may increase the temperature of the aerosol generating substance in the cigarette.

[0051] The heater 13 may be a resistive heater. For example, the heater 13 may include an electrically conductive track, and the heater 13 may be heated when current flows through the electrically conductive track. However, the heater 13 is not limited to the aforementioned example, and any example of heating the heater 13 to a desired temperature may be used without limitation. Here, the desired temperature may be pre-set in the aerosol generating device 1, or the desired temperature may be set by a user.

[0052] As another example, the heater 13 may be an induction heater. Specifically, the heater 13 may include an electrically conductive coil for heating the cigarette by induction heating, and the cigarette may include a susceptor to be heated by the induction heater.

[0053] For example, the heater 13 may include a tubular heating element, a plate heating element, a needle heating element, or a rod heating element, and may heat the inside or outside of the aerosol-generating article 2 according to the shape of the heating element.

[0054] In addition, a plurality of heaters 13 may be provided in the aerosol generating device 1. In this case, the plurality of heaters 13 may be arranged to be inserted into the aerosol generating article 2, or the plurality of heaters 13 may be arranged outside the aerosol generating article 2. In addition, some of the plurality of heaters 13 may be arranged to be inserted into the aerosol generating article 2, and the remaining heaters may be arranged outside the aerosol generating article 2. However, the shape of the heater 13 is not limited to Figures 1 to 3 The shape shown in FIG. 1 is not limited to the shape shown in FIG. 1 , but may be provided in various shapes.

[0055] The vaporizer 14 can heat the liquid composition to generate an aerosol, and the generated aerosol can pass through the aerosol generating article 2 to reach the user. In other words, the aerosol generated by the vaporizer 14 can travel along the airflow path of the aerosol generating device 1, and the airflow path can be configured so that the aerosol generated by the vaporizer 14 can pass through the cigarette to reach the user.

[0056] For example, the vaporizer 14 may include a liquid storage portion, a liquid delivery device, and a heating element. However, the embodiment is not limited thereto. For example, the liquid storage portion, the liquid delivery device, and the heating element may be included in the aerosol generating device 1 as independent modules.

[0057] The liquid storage portion can store a liquid composition. For example, the liquid composition can be a liquid comprising a tobacco-containing substance with a volatile tobacco aroma component, or a liquid comprising a non-tobacco substance. The liquid storage portion can be manufactured to be detachable from the vaporizer 14 and to be attached to the vaporizer 14, or can be manufactured to be in a form that is integral with the vaporizer 14.

[0058] For example, the liquid composition may include water, solvents, ethanol, plant extracts, spices, flavoring agents, or vitamin mixtures. Spices may include, for example, menthol, peppermint, spearmint oil, and various fruity ingredients. However, embodiments are not limited thereto. Flavoring agents may include ingredients that provide various scents or flavors to users. The vitamin mixture may be a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E. However, embodiments are not limited thereto. The liquid composition may also include an aerosol former such as glycerol and propylene glycol.

[0059] The liquid conveying device can convey the liquid composition in the liquid storage part to the heating element. For example, the liquid conveying device can be a wick, and the wick is, for example, cotton fiber, ceramic fiber, glass fiber, porous ceramic. However, the embodiment is not limited thereto.

[0060] The heating element may be an element for heating the liquid composition conveyed by the liquid conveying device. For example, the heating element may be a metal heating wire, a metal hot plate, a ceramic heater, etc. However, the embodiment is not limited thereto. In addition, the heating element may include a conductive wire such as a nickel-chromium alloy wire, and may be arranged to be wound around the liquid conveying device. The heating element may be heated when an electric current is supplied, and heat may be transferred to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, an aerosol may be generated.

[0061] For example, the vaporizer 14 may also be referred to as a cartomizer or an atomizer. However, the embodiment is not limited thereto.

[0062] In addition, in addition to the battery 11, the controller 12, the heater 13, and the vaporizer 14, the aerosol generating device 1 may also include other common components. For example, the aerosol generating device 1 may include a display that outputs visual information and / or a motor that outputs tactile information. In addition, the aerosol generating device 1 may include at least one sensor (e.g., a suction detection sensor, a temperature detection sensor, an aerosol generating article insertion detection sensor, etc.). In addition, the aerosol generating device 1 may be manufactured to have a structure that allows external air to be introduced or internal air to flow out even when the aerosol generating article 2 is inserted.

[0063] although Figures 1 to 3 Although not shown in the figure, the aerosol generating device 1 can constitute a system together with a separate cradle. For example, the cradle can be used to charge the battery 11 of the aerosol generating device 1. Alternatively, the cradle can be used to heat the heater 13 when the cradle is coupled to the aerosol generating device 1.

[0064] The aerosol-generating article 2 may be similar to a conventional combustion-type cigarette. For example, the aerosol-generating article 2 may be divided into a first portion including an aerosol-generating substance and a second portion including a filter or the like. Alternatively, the second portion of the aerosol-generating article 2 may also include an aerosol-generating substance. For example, an aerosol-generating substance provided in the form of particles or capsules may be inserted into the second portion.

[0065] The first part may be inserted as a whole into the aerosol generating device 1, and the second part may be exposed to the outside. Alternatively, only the first part may be partially inserted into the aerosol generating device 1, or the first part may be inserted as a whole into the aerosol generating device 1, and the second part may be partially inserted into the aerosol generating device 1. The user may inhale the aerosol with the second part located in the user's mouth. In this case, an aerosol may be generated when external air passes through the first part, and the generated aerosol may pass through the second part to reach the user's mouth.

[0066] For example, external air may be introduced through at least one air path formed in the aerosol generating device 1. In this example, the user may adjust the opening or closing of the air path formed in the aerosol generating device 1 and / or the size of the air path. Thus, the user may adjust the amount of atomization, the feeling of smoking, etc. As another example, external air may be introduced into the interior of the aerosol generating article 2 through at least one hole formed on the surface of the aerosol generating article 2.

[0067] Below, we will refer to Figure 4 and Figure 5 An example of an aerosol-generating article 2 is described below.

[0068] Figure 4 and Figure 5 is a diagram showing an example of an aerosol-generating article according to an embodiment.

[0069] Reference Figure 4 , the aerosol generating article 2 comprises a tobacco rod 21 and a filter rod 22. Figures 1 to 3 The depicted first portion 21 and second portion 22 may include a tobacco rod 21 and a filter rod 22, respectively.

[0070] exist Figure 4 In the embodiment, the filter rod 22 is shown as having a single segment. However, the embodiment is not limited thereto. In other words, alternatively, the filter rod 22 may include a plurality of segments. For example, the filter rod 22 may include a segment for cooling the aerosol and a segment for filtering a predetermined component contained in the aerosol. In addition, the filter rod 22 may also include at least one segment that performs other functions as required.

[0071] The diameter of the aerosol-generating article 2 may be in the range of about 5 millimeters (mm) to about 9 millimeters (mm), and the length of the aerosol-generating article 2 may be about 48 mm. However, the embodiments are not limited thereto. For example, the length of the tobacco rod 21 may be about 12 mm, the length of the first section of the filter rod 22 may be about 10 mm, the length of the second section of the filter rod 22 may be about 14 mm, and the length of the third section of the filter rod 22 may be about 12 mm. However, the embodiments are not limited thereto.

[0072] The aerosol generating article 2 can be packaged with at least one package 24. The package 24 can have at least one hole through which external air is introduced or internal gas flows out. As an example, the aerosol generating article 2 can be packaged with one package 24. As another example, the aerosol generating article 2 can be packaged with two or more packages 24 in an overlapping manner. For example, the tobacco rod 21 can be packaged with a first package 241, and the filter rod 22 can be packaged with packages 242, 243, and 244. In addition, the aerosol generating article 2 as a whole can be packaged again with a single package 245. For example, when the filter rod 22 includes a plurality of segments, each segment can be packaged with packages 242, 243, and 244, respectively.

[0073] The first package 241 and the second package 242 can be formed by general filtering packaging paper. For example, the first package 241 and the second package 242 can be porous packaging paper or non-porous packaging paper. In addition, the first package 241 and the second package 242 can be formed by oil-proof paper and / or aluminum laminated packaging material.

[0074] The third packaging member 243 may be formed of hard packaging paper. For example, the basis weight of the third packaging member 243 may be about 88 g / m 2 About 96g / m 2 In the range of about 90 g / m 2 About 94g / m 2 In addition, the thickness of the third package member 243 may be in the range of about 120 micrometers (μm) to about 130 micrometers (μm), and desirably may be 125 μm.

[0075] The fourth packaging member 244 can be formed of a hard packaging paper that is oil-proof. For example, the basis weight of the fourth packaging member 244 can be about 88 g / m 2 About 96g / m 2 In the range of about 90 g / m 2 About 94g / m 2 In addition, the thickness of the fourth package member 244 may be in the range of about 120 μm to about 130 μm, and desirably may be about 125 μm.

[0076] The fifth package 245 may be formed of sterile paper (e.g., MFW). Here, sterile paper (MFW) may refer to specially prepared paper such that the paper has increased tensile strength, water resistance, smoothness, etc. compared to general paper. For example, the basis weight of the fifth package 245 may be about 57 g / m 2 About 63g / m 2and may be about 60 g / m 2 In addition, the thickness of the fifth package member 245 may be in the range of about 64 μm to about 70 μm, and desirably may be 67 μm.

[0077] The fifth package 245 may have a predetermined material added inside. The material may be, for example, silicon. However, the embodiment is not limited thereto. Silicon has the following properties: for example, heat resistance, characterized by small temperature changes; oxidation resistance, resistance to various chemicals, water resistance, or electrical insulation. However, it is not necessary to use silicon, but any material having the above properties may be applied (or coated) to the fifth package 245 without limitation.

[0078] The fifth package 245 can prevent the aerosol-generating article 2 from burning. For example, when the tobacco rod 21 is heated by the heater 13, the aerosol-generating article 2 may burn. Specifically, when the temperature rises above the ignition point of any material included in the tobacco rod 21, the aerosol-generating article 2 may burn. Even in this case, since the fifth package 245 includes a non-combustible material, the aerosol-generating article 2 can still be prevented from burning.

[0079] In addition, the fifth packaging member 245 can prevent the holder 1 from being contaminated by substances generated in the aerosol-generating article 2. For example, liquid substances can be generated in the aerosol-generating article 2 when the user draws. For example, when the aerosol generated in the aerosol-generating article 2 is cooled by the external air, such liquid substances (e.g., moisture, etc.) can be generated. Since the aerosol-generating article 2 is packaged with the fifth packaging member 245, the liquid substances generated in the aerosol-generating article 2 can be prevented from leaking from the aerosol-generating article 2.

[0080] The tobacco rod 21 may include an aerosol-generating substance. The aerosol-generating substance may include, for example, at least one of glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. However, the embodiment is not limited thereto. The tobacco rod 21 may also include other additives, such as, for example, flavoring agents, wetting agents, and / or organic acids. In addition, the tobacco rod 21 may include a flavoring liquid, such as menthol or a moisturizer, etc., which is added when sprayed onto the tobacco rod 21.

[0081] The tobacco rod 21 can be manufactured in various forms. For example, the tobacco rod 21 can be formed into a sheet or a strand. Alternatively, the tobacco rod 21 can be formed into a tubular tobacco, which is formed by small pieces cut from a tobacco sheet. In addition, the tobacco rod 21 can be wrapped with a heat-conductive material. The heat-conductive material can be, for example, a metal foil, such as an aluminum foil. However, the embodiment is not limited to this. For example, the heat-conductive material wrapping the tobacco rod 21 can evenly distribute the heat transmitted to the tobacco rod 21 to improve the thermal conductivity to be applied to the tobacco rod, thereby improving the taste of the tobacco. In addition, the heat-conductive material wrapping the tobacco rod 21 can be used as a susceptor heated by an induction heater. In this case, although not shown, the tobacco rod 21 can include another susceptor in addition to the heat-conductive material wrapping the outside thereof.

[0082] The filter rod 22 may be a cellulose acetate filter. However, there is no limitation on the shape of the filter rod 22. For example, the filter rod 22 may be a cylindrical rod, or a tubular rod including a hollow portion therein. The filter rod 22 may also be a recessed rod. For example, when the filter rod 22 includes a plurality of segments, at least one of the segments may be manufactured in a different shape.

[0083] The first section of the filter rod 22 may be a cellulose acetate filter. For example, the first section may be a tubular structure including a hollow portion therein. When the heater 13 is inserted into the tobacco rod 21, the first section may prevent the inner material of the tobacco rod 21 from being pushed back, and the first section may cool the aerosol. The desired diameter of the hollow portion included in the first section may be adopted in the range of about 2 mm to about 4.5 mm. However, the embodiment is not limited thereto.

[0084] The desired length of the first segment can be in the range of about 4 mm to about 30 mm. However, the embodiment is not limited thereto. It is desirable that the length of the first segment can be 10 mm. However, the embodiment is not limited thereto.

[0085] The first segment may have a hardness that can be adjusted by adjusting the content of the plasticizer during the process of manufacturing the first segment. In addition, the first segment may be manufactured by inserting a structural member such as a film or a tube of the same or different material inside (eg, a hollow portion).

[0086] The second section of the filter rod 22 can cool the aerosol generated when the heater 13 heats the tobacco rod 21. Therefore, the user can inhale the aerosol cooled to a suitable temperature.

[0087] The length or diameter of the second segment can be determined in various ways according to the shape of the aerosol-generating article 2. For example, the desired length of the second segment can be adopted in the range of about 7 mm to about 20 mm. It is desirable that the length of the second segment can be about 14 mm. However, the embodiment is not limited thereto.

[0088] The second section may be manufactured by weaving polymer fibers. In this case, the flavoring liquid may be applied to the fibers formed of the polymer. As another example, the second section may be manufactured by weaving together separate fibers to which the flavoring liquid is applied and fibers formed of the polymer. As yet another example, the second section may be formed of a curled polymer sheet.

[0089] For example, the polymer may be prepared using a material selected from the group consisting of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polylactic acid (PLA), cellulose acetate (CA), and aluminum foil.

[0090] Since the second section is formed of woven polymer fibers or curled polymer sheets, the second section may include a single channel or multiple channels extending in the longitudinal direction.A channel as used herein may refer to a path through which a gas (eg, air or aerosol) passes.

[0091] For example, the second segment formed of the rolled polymer sheet can be formed of a material having a thickness between about 5 μm and about 300 μm, for example, the second segment formed of the rolled polymer sheet can be formed of a material having a thickness between about 10 μm and about 250 μm. In addition, the total surface area of ​​the second segment can be about 300 mm 2 / mm and about 1000mm 2 / mm. In addition, the aerosol-cooling element can be composed of a specific surface area of ​​about 10mm 2 / mg and about 100mm 2 / mg of material is formed.

[0092] In addition, the second segment may include a thread containing a volatile flavor component. The volatile flavor component may be menthol. However, the embodiment is not limited thereto. For example, the thread may be filled with a sufficient amount of menthol to provide at least 1.5 (mg) of menthol to the second segment.

[0093] The third section of the filter rod 22 may be a cellulose acetate filter. The desired length of the third section may be in the range of about 4 mm to about 20 mm. For example, the length of the third section may be about 12 mm. However, the embodiment is not limited thereto.

[0094] The third section can be manufactured so that flavor is generated by spraying flavoring liquid onto the third section during the manufacturing process of the third section. Alternatively, a separate fiber to which the flavoring liquid is applied can be inserted into the third section. The aerosol generated in the tobacco rod 21 can be cooled when the aerosol passes through the second section of the filter rod 22, and the cooled aerosol can pass through the third section to reach the user. Therefore, when the flavoring element is added to the third section, the fragrance transmitted to the user can last longer.

[0095] In addition, the filter rod 22 may include at least one capsule 23. Here, the capsule 23 may perform a function of generating flavor or a function of generating aerosol. For example, the capsule 23 may have a structure in which a liquid containing a flavor is film-wrapped. The capsule 23 may have a spherical or cylindrical shape. However, the embodiment is not limited thereto.

[0096] Reference Figure 5 The aerosol generating article 3 may further include a front end plug 33. The front end plug 33 may be arranged on a side of the tobacco rod 31 opposite to the filter rod 32. The front end plug 33 may prevent the tobacco rod 31 from escaping to the outside, and may also prevent the aerosol liquefied in the tobacco rod 31 from flowing into the aerosol generating device (e.g., Figures 1 to 3 Aerosol generating device 1).

[0097] The filter rod 32 may include a first section 321 and a second section 322. Here, the first section 321 may correspond to Figure 4 The first section of the filter rod 22, and the second section 322 may correspond to Figure 4 The third section of the filter rod 22.

[0098] The diameter and overall length of the aerosol-generating article 3 may correspond to Figure 4 The diameter and total length of the aerosol generating article 2. For example, the length of the front end plug 33 may be about 7 mm, the length of the tobacco rod 31 may be about 15 mm, the length of the first section 321 may be about 12 mm, and the length of the second section 322 may be about 14 mm. However, the embodiment is not limited thereto.

[0099] The aerosol generating article 3 may be packaged by at least one package 35. The package 35 may have at least one hole through which external air is introduced or through which internal gas flows out. For example, the front end plug 33 may be packaged by a first package 351, the tobacco rod 31 may be packaged by a second package 352, the first section 321 may be packaged by a third package 353, and the second section 322 may be packaged by a fourth package 354. In addition, the aerosol generating article 3 as a whole may be packaged again by a fifth package 355.

[0100] In addition, at least one perforation 36 may be formed in the fifth packing member 355. For example, the perforation 36 may be formed in a region surrounding the tobacco rod 31.

In addition, although Figure 6 Although not shown in the figure, the aerosol generating device 400 may also include a connection interface such as a universal serial bus interface, and may be connected to other external devices via a connection interface such as a USB interface to transmit and receive information or charge the battery 440.

[0133] The memory 470 is hardware for storing various data processed in the aerosol generating device 400, and the memory 470 can store data processed by the controller 410 and data to be processed. The memory 470 includes at least one type of the following storage media: flash memory, hard disk memory, multimedia card micro memory, card memory (such as SD or XD memory, etc.), random access memory, static random access memory, read-only memory, electrically erasable programmable read-only memory, programmable read-only memory, magnetic memory, magnetic disk, or optical disk.

[0137] The controller 410 may control the overall operation of the aerosol generating device 400. In an embodiment, the controller 410 may include at least one processor. The processor may be implemented as a plurality of logic gate arrays, or may be implemented as a combination of a general-purpose microprocessor and a memory, wherein the memory stores a program that can be executed by the microprocessor. In addition, it is understood by a person skilled in the art to which the present disclosure belongs that the processor may be implemented in other forms of hardware.

[0138] The controller 410 may control the temperature of the heater 450 by controlling the power provided by the battery 440 to the heater 450. For example, the controller 410 may control the supply of power by switching a switching element between the battery 440 and the heater 450. In another example, the direct heating circuit may control the supply of power to the heater 450 according to a control command of the controller 110.

[0139] The controller 410 may analyze the sensing result obtained by the sensing of the sensing unit 420 and control the subsequent process to be performed. For example, the controller 410 may control the power to be supplied to the heater 450 based on the sensing result obtained by the sensing unit 420, thereby turning on and off the operation of the heater 450. In another example, the controller 410 may control the amount of power to be supplied to the heater 450 and the time for supplying the power based on the sensing result obtained by the sensing unit 420, so that the heater 450 may be heated to a predetermined temperature or maintained at a suitable temperature.

[0140] Controller 410 may control output unit 430 based on the sensing result obtained by sensing unit 420. For example, when the number of puffs counted by puff sensor 426 reaches a preset number, controller 410 may notify the user through at least one of display 432, tactile portion 434, or sound outputter 436 that aerosol generating device 400 is about to be stopped.

[0141] According to an embodiment, the controller 410 may control the power supply time and / or power supply amount to the heater 450 according to the state of the aerosol generating product sensed by the sensing unit 420. For example, when the aerosol generating product (e.g., the aerosol generating product 201) is in an over-humidified state, the controller 410 may control the power supply time to the induction coil, thereby extending the preheating time compared to the case of the aerosol generating product in a normal state.
