Description

TECHNICAL FIELD

[0001] According to various embodiments of the present disclosure, there are provided an aerosol generating system, a method of operating the same, and an aerosol generating article included in the aerosol generating system, which determines information of the aerosol generating article based on a sensed value sensed by a light emitting material included in the aerosol generating article. BACKGROUND

[0002] In recent years, there is an increasing demand for alternative methods to overcome the shortcomings of conventional cigarettes. For example, there is an increasing demand for a system that generates an aerosol by heating a cigarette or an aerosol generating material using an aerosol generating device, rather than by combusting a cigarette.

[0003] In recent years, there is a tendency for the types of sensors included in an aerosol generating device to diversify in order to sense whether a cigarette is inserted / removed, the type of a cigarette, and whether a cigarette is counterfeit, etc. In particular, as the types of cigarettes diversify and counterfeit cigarettes are present on the market, there is an increasing demand for an aerosol generating device having a function capable of distinguishing between the same.

[0004] However, for various reasons, the sensed value of a sensor in an aerosol generating device can deteriorate, or a heater or the like for heating a cigarette can limit the implementation of sensor performance. For example, in the case of an aerosol generating device that automatically determines whether a cigarette is counterfeit for the convenience of a user and performs a function of stopping the operation of a heater when it is determined that the cigarette is counterfeit, if the accuracy of the sensor is low and causes a malfunction, it can rather adversely affect the user's experience of use.

[0005] In addition, as the trend of individualization accelerates recently, a customized cigarette that satisfies the preferences of various users is being produced. As described above, rather than mass-producing a small number of types of cigarettes, a method of producing a small number of cigarettes in a large number of types can cause limitations in a method of identifying the types of cigarettes by relying only on limited identification means.

[0006] In addition, since an aerosol generating device belongs to a small electronic product, the assembly space of electronic components is limited, and it is inevitable that a power consumption problem caused by a battery capacity limitation can occur. SUMMARY

[0007] PROBLEMS TO BE SOLVED BY THE INVENTION By the present disclosure, it is possible to provide an aerosol generating device in which the sensitivity of a sensor is improved.

[0008] In addition, by the present disclosure, it is possible to provide an aerosol generating device capable of identifying a plurality of types of cigarettes using limited identification means.

[0023] A reflective substance can be disposed on the inclined surface.

[0024] The partition wall can be formed of black epoxy molding compound, and the molding member can be formed of transparent molding compound.

[0083] Hereinafter, the embodiments will be described in detail with reference to the attached drawings.

[0084] Hereinafter, the present application will be described in detail by referring to the attached drawings, so that one of ordinary skill in the art can easily practice the present application. However, the present application can be implemented in various different forms, and is not limited to the embodiments described herein.​​Figures 1 to 3 An example of an aerosol generating article will be described.

[0085] Figures 1 to 3 A diagram illustrating an example of an aerosol generating article.

[0086] Figure 1 In the example, the filter rod 22 is illustrated as a single segment, but is not limited thereto. In other words, the filter rod 22 can also be composed of a plurality of segments. For example, the filter rod 22 can include a first segment for cooling an aerosol and a second segment for filtering a predetermined component contained in the aerosol. In addition, if necessary, at least one segment performing other functions can also be included in the filter rod 22.

[0087] The aerosol generating article 2 can be wrapped by at least one wrapper 24. At least one hole can be formed in the wrapper 24 to allow external air to flow in or internal gas to flow out. As an example, the aerosol generating article 2 can be wrapped by one wrapper 24. As another example, the aerosol generating article 2 can also be wrapped by two or more wrappers 24 in a superposed manner. For example, the tobacco rod 21 can be wrapped by a first wrapper 24a, and the filter rod 22 can be wrapped by wrappers 24b, 24c, 24d. Also, the entire aerosol generating article 2 can be re-wrapped by a single wrapper 24e. If the filter rod 22 is composed of a plurality of segments, each segment can be wrapped by the wrappers 24b, 24c, 24d.

[0088] The tobacco rod 21 contains an aerosol generating material. For example, the aerosol generating material can contain at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol, but is not limited thereto. In addition, the tobacco rod 21 can contain other additive materials such as a flavoring agent, a humectant, and / or an organic acid. In addition, the tobacco rod 21 can be added by spraying a perfuming liquid such as menthol or a moisturizing agent to the tobacco rod 21.

[0089] The tobacco rod 21 can be manufactured in various ways. For example, the tobacco rod 21 can be manufactured as a sheet, or as a strand. In addition, the tobacco rod 21 can also be manufactured from tobacco shreds cut from a tobacco sheet. In addition, the tobacco rod 21 can also be surrounded by a heat conductive material. For example, the heat conductive material can be a metal foil such as an aluminum foil, but is not limited thereto. As an example, the heat conductive material surrounding the tobacco rod 21 can uniformly disperse heat transferred to the tobacco rod 21, thereby increasing the heat conductivity applied to the tobacco rod, and further improving the taste of the tobacco. In addition, the heat conductive material surrounding the tobacco rod 21 can function as a susceptor heated by an induction heating type heater. At this time, although not illustrated in the drawings, the tobacco rod 21 can include an additional susceptor in addition to the heat conductive material surrounding the outside.

[0090] The filter rod 22 can be a cellulose acetate filter. In another aspect, the shape of the filter rod 22 is not limited. For example, the filter rod 22 can be a cylindrical rod, or a tubular rod having a hollow portion inside. In addition, the filter rod 22 can be an embedded rod. If the filter rod 22 is composed of a plurality of segments, at least one of the plurality of segments can also be made in a different shape.

[0091] The filter rod 22 can also be made to generate a flavor. As an example, a flavoring liquid can be sprayed to the filter rod 22, or a separate fiber coated with a flavoring liquid can be inserted into the inside of the filter rod 22.

[0092] In addition, at least one capsule 23 can also be included in the filter rod 22. Here, the capsule 23 can generate a flavor or an aerosol. For example, the capsule 23 can be a structure in which a liquid containing a flavor is wrapped with a film. The capsule 23 can have a spherical or cylindrical shape, but is not limited thereto.

[0093] If a segment for cooling an aerosol is included in the filter rod 22, the cooling segment can be made of a high molecular substance or a biodegradable high molecular substance. For example, the cooling segment can be made of only pure polylactic acid, but is not limited thereto. Alternatively, the cooling segment can be made of a cellulose acetate filter having a plurality of holes. However, the cooling segment is not limited to the above-described examples, and can be applied without limitation as long as it can perform a function of cooling an aerosol.

[0094] Referring to Figure 2 , the aerosol generating article 3 can further include a front end plug 33. The front end plug 33 can be located at a side opposite to the filter rod 32 in the tobacco rod 31. The front end plug 33 can prevent the tobacco rod 31 from being detached to the outside, and can prevent an aerosol liquefied from the tobacco rod 31 from flowing into an aerosol generating device during smoking.

[0095] The filter rod 32 can include a first segment 321 and a second segment 322. Here, the first segment 321 can correspond to the first segment of the filter rod 22 in Figure 1 , and the second segment 322 can correspond to the second segment of the filter rod 22 in Figure 1 .

[0096] The diameter and the overall length of the aerosol generating article 3 can correspond to the diameter and the overall length of the aerosol generating article 2 in Figure 1 . For example, the length of the front end plug 33 can be about 7 mm, the length of the tobacco rod 31 can be about 15 mm, the length of the first segment 321 can be about 12 mm, and the length of the second segment 322 can be about 14 mm, but is not limited thereto.

[0097] The aerosol generating article 3 can be wrapped by at least one wrapper 35. At least one hole can be formed in the wrapper 35 to allow external air to flow in or internal gas to be discharged. For example, a first wrapper 35a can be used to wrap the front end plug 33, a second wrapper 35b can be used to wrap the tobacco rod 31, a third wrapper 35c can be used to wrap the first segment 321, and a fourth wrapper 35d can be used to wrap the second segment 322.

[0098] Also, a fifth wrapper 35e can be used to rewrap the aerosol generating article 3 as a whole. Also, at least one perforation 36 can be formed in the fifth wrapper 35e. For example, the perforation 36 can be formed in a region surrounding the tobacco rod 31, but is not limited thereto. The perforation 36 can function to transfer heat generated by the heater to the inside of the tobacco rod 31.

[0099] Also, the second segment 322 can include at least one capsule 34. Here, the capsule 34 can generate a flavor or an aerosol. For example, the capsule 34 can be a structure in which a liquid containing a flavor is wrapped with a film. The capsule 34 can have a spherical or cylindrical shape, but is not limited thereto.

[0100] Figure 3 FIG. 1 is a view illustrating one example of an aerosol generating article.

[0101] Referring to Figure 3 The aerosol generating article 4 can include a first aerosol generating rod 41, a second aerosol generating rod 42, a cooling rod 43, and a filter rod 44. Also, the aerosol generating article 4 can be wrapped by at least one wrapper 45.

[0102] The first aerosol generating rod 41, the second aerosol generating rod 42, the cooling rod 43, and the filter rod 44 can be aligned in sequence in a length direction of the aerosol generating article 4. Here, the length direction of the aerosol generating article 4 can be a direction in which the aerosol generating article 4 extends in length. For example, the length direction of the aerosol generating article 4 can be a direction from the first aerosol generating rod 41 toward the filter rod 44.

[0103] Aerosols generated by the first aerosol generating rod 41 and the second aerosol generating rod 42 can pass through the first aerosol generating rod 41, the second aerosol generating rod 42, the cooling rod 43, and the filter rod 44 in sequence, thereby forming an air flow that a smoker can inhale from the filter rod 44.

[0104] The first aerosol generating rod 41 can be heated to generate an aerosol. The first aerosol generating rod 41 can include an aerosol generating material. The first aerosol generating rod 41 can contain other additive materials such as a humectant and / or an organic acid, and can contain a flavoring liquid such as menthol.

[0105] The first aerosol generating rod 41 can include an aerosol generating substrate impregnated with an aerosol generating material. The aerosol generating substrate can include a crimped sheet, and the aerosol generating material can be included in the first aerosol generating rod 41 in a state of being impregnated in the crimped sheet. In addition, other additive materials such as a flavoring agent, a humectant, and / or an organic acid, and a flavoring liquid can be included in the first aerosol generating rod 41 in a state of being absorbed in the crimped sheet.

[0106] The aerosol generating substrate can be disposed in a wound state inside the first aerosol generating rod 41. The wound aerosol generating substrate can be wound around an axis extending in the length direction of the aerosol generating article 4, but is not limited thereto.

[0107] The crimped sheet can be a sheet material composed of a high molecular material. For example, the high molecular material can include at least one of paper, cellulose acetate, lyocell, and polylactic acid. For example, the crimped sheet can be a paper sheet that does not generate an odor due to heat even under high-temperature heating.

[0108] The first aerosol generating rod 41 can extend from the end of the aerosol generating article 4 to a position of about 7 mm to about 20 mm, and the second aerosol generating rod 42 can extend from the end of the first aerosol generating rod 41 to a position of about 7 mm to about 20 mm. However, it is not necessarily limited to the numerical range, and the extension length of each of the first aerosol generating rod 41 and the second aerosol generating rod 42 can be appropriately adjusted within a range that can be easily changed by one of ordinary skill in the art.

[0109] The second aerosol generating rod 42 can be heated to generate an aerosol containing nicotine. For example, the second aerosol generating rod 42 can include a tobacco material. The tobacco material can be in the form of a tobacco shred, a tobacco particle, a tobacco sheet, a tobacco bead, a tobacco granule, a tobacco powder, or a tobacco extract, but is not limited thereto.

[0110] For example, the second aerosol generating rod 42 can include a plurality of tobacco shreds, and the plurality of tobacco shreds can include reconstituted tobacco shreds. The reconstituted tobacco shreds can be prepared by shredding a reconstituted tobacco sheet. The reconstituted tobacco shreds can be prepared by the following process. After pulverizing a tobacco raw material, a slurry is prepared by mixing an aerosol generating material (e.g., glycerol, propylene glycol, etc.), a flavoring liquid, a binder (e.g., guar gum, xanthan gum, carboxymethyl cellulose, etc.), and water. Natural pulp or cellulose can be added to the slurry, and more than one binder can be mixed and used. The slurry can be cast to form a sheet, and the reconstituted tobacco sheet can be prepared after a drying process. The reconstituted tobacco shreds can be prepared by cutting or shredding the prepared reconstituted tobacco sheet. The tobacco raw material can be tobacco leaves, tobacco stems, and / or tobacco fines generated in a tobacco processing process. In addition, the reconstituted tobacco sheet can further include other additives such as lignocellulosic fibers.

[0111] In addition, the second aerosol generating rod 42 can include tobacco shreds prepared by cutting a mixture of a plurality of types of tobacco leaves. In addition, the second aerosol generating rod 42 can include a mixture of reconstituted tobacco shreds and tobacco shreds.

[0112] As another example, the second aerosol generating rod 42 can include a plurality of tobacco granules. The tobacco granules can be granules having a diameter of about 100 µm to about 2000 µm. The tobacco granules can be prepared by mixing a tobacco leaf powder, a pH adjuster, and a solvent and then extruding the mixture.

[0113] The plurality of tobacco granules can be disposed between filter materials. The filter materials can include, for example, a bundle of cellulose acetate fibers polymerized to form a fiber bundle. The plurality of tobacco granules can be disposed in a state of being uniformly dispersed between the plurality of cellulose acetate fibers. As another example, the filter materials can include a crimped paper sheet. The crimped paper sheet can be disposed in a crimped state inside the second aerosol generating rod 42. The crimped paper sheet can be crimped around an axis extending in a length direction of the aerosol generating article 4. The plurality of tobacco granules can be dispersedly disposed inside the crimped paper sheet.

[0114] In addition, the second aerosol generating rod 42 can include an aerosol generating substrate impregnated with a liquid aerosol generating composition. The aerosol generating substrate can include a crimped sheet, and the liquid aerosol generating composition can be included in the second aerosol generating rod 42 in a state of being impregnated in the crimped sheet. The foregoing description of the aerosol generating substrate included in the first aerosol generating rod 41 can be equally applicable to the aerosol generating substrate included in the second aerosol generating rod 42.

[0115] The liquid aerosol-generating composition can include nicotine. The nicotine can include freebase nicotine and nicotine salt. The freebase nicotine can refer to neutral nicotine to which no proton is added. For example, when a strong base such as ammonia is added to a positively charged nicotine salt, the strong base can be converted into a cation and the nicotine salt can become freebase nicotine in a neutral state.

[0116] In addition, the liquid aerosol-generating composition can include an aerosol-generating material. The same can apply to the foregoing with respect to the aerosol-generating material included in the first aerosol-generating rod 41.

[0117] The liquid aerosol-generating composition can be impregnated in an amount of about 0.05 g to about 1.0 g per 1 g of the aerosol-generating material. For example, the liquid aerosol-generating composition can be impregnated in an amount of about 0.1 g to about 0.8 g per 1 g of the aerosol-generating material.

[0118] The cooling rod 43 can cool the aerosol generated by the first aerosol-generating rod 41 and the second aerosol-generating rod 42. The cooling rod 43 can be made of a biodegradable high molecular material and can have a cooling function. For example, the cooling rod 43 can be made of a polylactic acid (PLA) fiber, but is not limited thereto.

[0119] Alternatively, the cooling rod 43 can be made of a cellulose acetate filter. However, the cooling rod 43 is not limited to the above-described example, and a material capable of performing a function of cooling the aerosol can be applied thereto without limitation. For example, the cooling rod 43 can be a tubular filter including a hollow portion or a paper tube made of paper.

[0120] At least one hole 431 can be formed at an outer surface of the cooling rod 43. The at least one hole 431 can be formed in a circumferential direction of the cooling rod 43, thereby forming more than one row. The at least one hole 431 can introduce external air into the inside of the cooling rod 43. The external air flowing into the inside of the cooling rod 43 can mix with the high-temperature aerosol generated by the first aerosol-generating rod 41 and the second aerosol-generating rod 42, thereby cooling the aerosol.

[0121] The filter rod 44 can filter part of the components included in the aerosol passing through the filter rod 44. The filter rod 44 can include a filter material. For example, the filter rod 44 can be a cellulose acetate filter. The filter rod 44 can be made by adding a plasticizer (e.g., triacetin) to a cellulose acetate tow.

[0122] The shape of the filter rod 44 is not limited. For example, the filter rod 44 can be a cylindrical rod, or a tubular rod having a hollow portion inside. Alternatively, the filter rod 44 can be an embedded rod having an open end and a hollow portion. If the filter rod 44 is composed of a plurality of segments, at least one of the plurality of segments can be made in a different shape.

[0123] The filter rod 44 can also be made to generate a flavor. As an example, the filter rod 44 can contain a flavoring liquid, or a separate fiber containing a flavoring liquid can be inserted into the inside of the filter rod 44.

[0124] In addition, the filter rod 44 can contain at least one capsule. Here, the capsule can generate a flavor or an aerosol. For example, the capsule can be a structure in which a liquid containing a flavor is wrapped with a film. The capsule can be spherical or cylindrical, but is not limited thereto.

[0125] The aerosol generating article 4 can include a wrapper 45 surrounding at least a portion of the first aerosol generating rod 41 to the filter rod 44. In addition, the aerosol generating article 4 can include a wrapper 45 surrounding all of the first aerosol generating rod 41 to the filter rod 44. The wrapper 45 can be located at the outermost side of the aerosol generating article 4, and the wrapper 45 can be a single wrapper or a combination of a plurality of wrappers.

[0126] The aerosol generating article 4 can be wrapped by two or more wrappers overlapping each other. For example, a first wrapper 45a can be used to wrap the first aerosol generating rod 41, a second wrapper 45b can be used to wrap the second aerosol generating rod 42, a third wrapper 45c can be used to wrap the cooling rod 43, and a fourth wrapper 45d can be used to wrap the filter rod 44. Also, a fifth wrapper 45e can be used to rewrap the entire aerosol generating article 4.

[0127] The first wrapper 45a can surround the first aerosol generating rod 41, and the second wrapper 45b can surround the second aerosol generating rod 42. The first wrapper 45a and the second wrapper 45b can be a structure in which paper and a metal foil such as an aluminum foil are combined. For example, the first wrapper 45a and the second wrapper 45b can be a laminate sheet in which paper and a metal foil are laminated. The first wrapper 45a and the second wrapper 45b can be a laminate sheet in which one surface of a metal foil is provided with paper, or a laminate sheet in which both surfaces of a metal foil are provided with paper.

[0128] The paper of the first wrapper 45a can contain an oil-resistant substance. For example, the paper of the first wrapper 45a can contain polyvinyl alcohol (PVOH) or silicone. The paper of the first wrapper 45a can be coated with polyvinyl alcohol or silicone on the surface.

[0129] The third wrapping paper 45c can surround the cooling rod 43. The third wrapping paper 45c can include a paper web. The paper web of the third wrapping paper 45c can be a porous paper web or a non-porous paper web. At least one perforation 45f can be formed in the third wrapping paper 45c. For example, the third wrapping paper 45c can wrap the cooling rod 43 in which at least one hole 431 is formed, and the at least one perforation 45f formed in the third wrapping paper 45c can be formed at a position corresponding to the at least one hole 431 formed in the cooling rod 43.

[0130] The fourth wrapping paper 45d can surround the filter rod 44. The fourth wrapping paper 45d can include a hard paper web having a greater thickness and a greater basis weight than a general paper web. For example, the hard paper web can have a thickness of about 70 um to about 150 um and a basis weight of about 50 g / m 2 to about 100 g / m 2 In addition, the hard paper web can include an oil-resistant substance. For example, the hard paper web can include a surface treatment by an oil-resistant substance such as polyvinyl alcohol or silicone.

[0131] The fifth wrapping paper 45e can entirely surround the first aerosol generating rod 41 wrapped by the first wrapping paper 45a, the second aerosol generating rod 42 wrapped by the second wrapping paper 45b, the cooling rod 43 wrapped by the third wrapping paper 45c, and the filter rod 44 wrapped by the fourth wrapping paper 45d. The fifth wrapping paper 45e can prevent the outside of the aerosol generating article 4 from being contaminated due to the aerosol generated by the aerosol generating article 4. By the user's puffing, a liquid substance can be generated within the aerosol generating article 4. For example, the aerosol generated in the aerosol generating article 4 is cooled by the outside air, and thus a liquid substance (e.g., moisture, etc.) can be generated. When the fifth wrapping paper 45e wraps the outer surface of the aerosol generating article 4, the generated liquid substance can be prevented from leaking to the outside of the aerosol generating article 4.

[0132] Embodiments of the disclosure relate to an aerosol generating article and an aerosol generating device that can distinguish between different types of aerosol generating articles and identify aerosol generating articles suitable for use with the aerosol generating device and aerosol generating articles unsuitable for use with the aerosol generating device.

[0133] To this end, the aerosol generating article according to an embodiment can include an identification substance. The identification substance can be disposed in one component of the aerosol generating article. For example, the identification substance can be disposed in a wrapping paper, a filter rod, a tobacco rod, a front end plug, and / or an aerosol generating rod. The following embodiments will be described based on the example in which the identification substance is disposed in a wrapping paper, but as described above, the component in which the identification substance can be disposed can vary.

[0134] The recognition substance can have a physical, chemical, or optical property. The recognition substance can be a substance having a property of changing a wavelength of received light and emitting. Specifically, the recognition substance can be excited by absorbing light of a predetermined wavelength range. In the present disclosure, "a substance is excited" can mean a state of the substance is changed from a ground state to an excited state. Subsequently, the recognition substance can emit light of a predetermined wavelength range in a process in which the state of the recognition substance is changed from the excited state to the ground state. For example, the recognition substance can be a substance contained in a lanthanide series, and can include a substance composed of at least one element between atomic numbers 57 and 71.

[0135] In an embodiment, the recognition substance can include a taggant. The taggant can include a signature capable of being recognized when absorbing light and / or emitting light. The taggant can absorb a specific range of wavelengths in a case in which the light irradiation part of the aerosol generating device irradiates light. The taggant can be excited by absorbing light, and can emit at least one transition light from the wavelength of the excitation light. At this time, the light emitted by the taggant can be in the form of photoluminescence, and can be phosphorescence or fluorescence.

[0136] The light emitted by the taggant having a specific range of wavelengths can be received by the light receiving part of the aerosol generating device. Based on the wavelength of the light received by the light receiving part, the aerosol generating device can recognize the kind of the aerosol generating article.

[0137] The specific range of wavelengths emitted by the taggant can be determined by the amount, concentration, kind, and / or composition ratio of the taggant substance.

[0138] The taggant can include an organic substance. In an embodiment, the taggant can include an organic substance selected from one or more of the group consisting of a quinazolinone-based compound, a thiophene-based compound, a sulfobenzoic acid-based compound, and a naphthyridine-based compound.

[0139] The quinazolinone-based compound can include a quinazolinone derivative or a salt thereof. For example, the quinazolinone-based compound can include 4(3H)-quinazolinone, 6-chloro-2-(5-chloro-2-hydroxyphenyl); 4(3H)-quinazolinone, 6-chloro-2-(4-chloro-2-hydroxyphenyl); 4(3H)-quinazolinone, 7-chloro-2-(5-chloro-2-hydroxyphenyl); 2-(5-chloro-2-hydroxy-phenyl)-3H-quinazolin-4-one.

[0140] The thiophene-based compound can include a thiophene derivative or a salt thereof. For example, the thiophene-based compound can include 2,5-bis(5-tert-butyl-2-benzoxazolyl)thiophene.

[0141] The sulfobenzoic acid-based compound can include a sulfobenzoic acid derivative or a salt thereof. For example, the sulfobenzoic acid-based compound can include benzoic acid, 2-[(2-hydroxy-5-sulfophenyl)methyl]amino]-, monosodium salt.

[0142] The naphthyridine-based compound can include a naphthyridine derivative or a salt thereof. For example, the naphthyridine-based compound can include a 1,8-naphthyridine derivative; a 1,5-naphthyridine derivative.

[0143] In addition, the marker can include an inorganic substance. In an embodiment, the marker can include one or more inorganic substances selected from the group consisting of a rare earth, an Actinide metal oxide, and a ceramic. For example, the rare earth can include one lanthanide selected from the group consisting of lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium.

[0144] In addition, the marker can be a substance in which an organic substance and an inorganic substance are combined. In an embodiment, the marker can include a substance in which an organic substance and an inorganic substance are combined by a covalent bond, a coordination bond, an ionic bond, or a covalent bond. For example, the marker can be a substance in which a lanthanide inorganic substance and an organic substance are combined by a coordination bond. For example, the marker can include europium, tris[7-chloro-1-cyclopropyl-6-fluoro-1,4-dihydro-4-(oxo-κO)-1,8-naphthyridine].

[0145] The difference between the maximum absorption wavelength (Abs max The difference between the maximum absorption wavelength (Abs

[0146] Experimental Example: Light emission experiment of a recognition substance including a marker After irradiating light to the recognition substance containing the marker, the wavelength of the emitted light was confirmed. The wavelength of the irradiated light was 365 nm, and the main wavelength of the emitted light was measured, and the results are described in Table 1 below.

[0147] Example 1 described in Table 1 is 4(3H)-quinazolinone, 6-chloro-2-(5-chloro-2-hydroxyphenyl) as a quinazolinone compound, Example 2 is 2-(5-chloro-2-hydroxy-phenyl)-3H-quinazolin-4-one as a quinazolinone compound, Example 3 is a mixture of 2,5-bis(5-tert-butyl-2-benzoxazolyl)thiophene as a thiophene compound and benzoic acid, 2-[(2-hydroxy-5-sulfophenylcarbonyl)amino]-, monosodium salt as a sulfobenzoic acid compound (85~90:10~15 weight ratio), and Example 4 is europium, tris[7-chloro-1-cyclopropyl-6-fluoro-1,4-dihydro-4-(oxo-KO)-1,8-naphthyridine].

[0148] [Table 1]

[0149] As can be confirmed from Table 1, Examples 1 to 4 can absorb light and be excited, and the wavelength of the emitted light is different from the wavelength of the absorbed light. In addition, Examples 1 to 4 can confirm that the difference between the maximum absorption wavelength (Abs max ) of the irradiated light and the main wavelength of the emitted light is about 20% or more based on the maximum absorption wavelength (Example 1: about 38%, Example 2: about 36%, Example 3: about 29%, Example 4: about 63%).

[0150] The marker can be prepared by being added to a paper pulp or paper paste before drying the constituent element (e.g., a wrapping paper) of the aerosol generating article, or by being coated or sprayed on the constituent element. The marker can be contained in the constituent element of the aerosol generating article at a content of the order of nanograms.

[0151] In an embodiment, the aerosol generating article can contain the marker at a first content or more. Accordingly, the aerosol generating article can contain a sufficient amount of the marker so that light of a specific wavelength range can be emitted. As an example, when the marker is sprayed on a surface, the spraying solution can contain the marker at a concentration of about 1 ppm to about 1000 ppm. As another example, the marker can also be contained in the wrapping paper at a content of about 6 mg / mm 2 The above amount is contained on the wrapping paper.

[0152] In an embodiment, an identification substance solution can be coated on a surface of a constituent element of an aerosol generating article. The identification substance solution can refer to a liquid composition including an identification substance. For example, the identification substance solution can be used to coat a surface of a wrapping paper of the aerosol generating article. As another example, the identification substance solution can be printed on a surface of a wrapping paper of the aerosol generating article.

[0153] For example, the identification substance solution can be prepared according to a preparation method including a step of preparing an identification substance, a step of mixing the identification substance with an OP varnish to prepare a first solution, and a step of mixing the first solution with a diluent to prepare the identification substance solution. The prepared identification substance can be applied to a constituent element of an aerosol generating article.

[0154] The step of preparing the identification substance can be a pre-treatment step performed in such a way that the identification substance has a shape or a property suitable for being applied to a constituent element of an aerosol generating article. For example, the identification substance included in the identification substance solution can be a plurality of particles having a diameter of about 0.1 μm to about 10 μm. The identification substance can be processed by grinding to have a diameter in the aforementioned range. When the identification substance has a diameter in the aforementioned range, the identification substance can be uniformly dispersed on a surface of an aerosol generating article coated with the identification substance solution, and thus printability can be improved. When the identification substance has a diameter less than about 0.1 μm, it can be difficult to detect light emitted by the identification substance. When the identification substance has a diameter exceeding about 10 μm, it can be difficult to achieve uniform dispersion of the identification substance, and printability can be reduced. The identification substance can have a diameter of, for example, about 0.5 μm to about 5 μm, or about 0.7 μm to 3 μm.

[0155] The identification substance solution can include an OP varnish. In the present disclosure, the OP varnish can refer to a liquid coating solidified by curing. For example, the OP varnish can include one or more substances selected from the group consisting of nitrocellulose, polyamide, propyl acetate, isopropyl alcohol, ethyl acetate, and 1,2-cyclohexanedicarboxylic acid diisononyl ester (DINCH).

[0156] The solution of the identification substance can include a diluent. The diluent can be a diluent known in the art for intaglio printing or lithography. For example, the diluent can include one or more selected from the group consisting of water, an alcohol having 1 to 4 carbon atoms, a vegetable oil, a fatty amine, propyl acetate, isopropyl alcohol, and ethyl acetate. The vegetable oil can include one or more selected from the group consisting of linseed oil, soybean oil, castor oil, corn oil, tung oil, otticita oil, and coconut oil. The fatty amine can be one or more selected from the group consisting of oleyl amine, stearyl amine, and oleoyl diamine.

[0157] For example, the solution of the identification substance can include the identification substance in an amount of about 0.01% to about 20% by weight, the OP varnish in an amount of about 10% to about 40% by weight, and the diluent in an amount of about 50% to about 85% by weight, but is not limited thereto. The solution of the identification substance can include the identification substance in an amount of about 0.05% to about 10% by weight, the OP varnish in an amount of about 15% to about 30% by weight, and the diluent in an amount of about 60% to about 80% by weight.

[0158] Hereinafter, a plurality of embodiments regarding the configuration position / way of the identification substance will be sequentially viewed. Figures 4a to 4d

[0159] Figures 4a to 4d A side cross-sectional view of an aerosol generating article for illustrating an example of a configuration position / way of an identification substance.

[0160] Referring to Figures 4a to 4d , the cigarette 5 can include the identification substance 10, a tobacco rod 51, a filter rod 52, and a wrapper 53. In Figures 4a to 4d at least one of the constituent elements of the cigarette 5 illustrated in FIG. 1 is the same as or similar to at least one of the constituent elements of the aerosol generating article described above, and thus repeated explanations will be omitted hereinafter. Also, referring to the following drawings and explanations, of course, part of the constituent elements and structures can be replaced, added, or omitted within a range that can be easily understood by those skilled in the art.

[0161] Referring to Figure 4a , the identification substance 10 can be disposed uniformly along the length direction of the wrapper 53 over the entire area of the wrapper 53. Accordingly, the sensor module of the aerosol generating device can sense the entire area of the wrapper 53 in which the identification substance 10 is arranged, and thus the degree of freedom of the configuration structure of the sensor module can be improved. Accordingly, the easiness of the manufacturing process of the aerosol generating device can be improved.

[0162] ​Further, since the identification substance 10 is exposed to the outer surface of the wrapper 53, the sensor module of the aerosol-generating device can easily identify the identification substance 10. That is, the sensitivity of the sensor module can be improved.

[0163] Figure 4a The illustrated identification substance 10 can be uniformly disposed in the entire area of the wrapper 53 by being added to the paper pulp or paper paste during the manufacturing process of the wrapper 53.

[0164] Referring to Figure 4b , the identification substance 10 can be disposed on the outer circumferential surface of the wrapper 53 in the length direction of the wrapper 53. Accordingly, the sensor module of the aerosol-generating device can sense the entire area of the length direction of the wrapper 53 in which the identification substance 10 is arranged, and thus the degree of freedom of the configuration structure of the sensor module can be improved.

[0165] Further, since the identification substance 10 is exposed to the outer surface of the wrapper 53, the sensor module of the aerosol-generating device can easily identify the identification substance 10. That is, the sensitivity of the sensor module can be improved.

[0166] Further, based on the improved sensitivity, the amount of use of the identification substance 10 can be reduced compared to the illustrated embodiment. Figure 4a

[0167] Figure 4b The illustrated identification substance 10 can be disposed in the length direction of the wrapper 53 in a manner of being sprayed on the surface of the wrapper 53.

[0168] Referring to Figure 4c , the identification substance 10 can be disposed on the inner surface of the wrapper 53 in the length direction of the wrapper 53. Accordingly, the identification substance 10 can not be separated from the wrapper 53 without a separate adhesive. Accordingly, the accuracy of the work of the aerosol-generating device to identify the identification substance 10 can be improved, and a process for adhering the identification substance 10 to the wrapper 53 in the manufacturing process of the cigarette 5 can be omitted.

[0169] Figure 4c The illustrated identification substance 10 can be disposed on the inner surface of the wrapper 53 in a manner of being sprayed on the inner surface of the wrapper 53. At this time, the thickness of the wrapper 53 can be set to an appropriate range so that the sensor module of the aerosol-generating device can identify the identification substance 10 disposed on the inner surface of the wrapper 53. For example, the thickness of the wrapper 53 can be in the range of about 10 μm to about 200 μm.

[0170] Referring to Figure 4d ​The two wrapping papers 53 can overlap around the cigarette 5. The identification substance 10 can be disposed in the length direction between the two overlapping wrapping papers 53. Accordingly, the identification substance 10 can not be separated from the wrapping paper 53 without a separate adhesive. Accordingly, the accuracy of the operation of the aerosol generating device to identify the identification substance 10 can be improved, and a process for adhering the identification substance 10 to the wrapping paper 53 in the manufacturing process of the cigarette 5 can be omitted.

[0171] In addition, compared to the embodiment illustrated in FIG. 1, the sensor module of the aerosol generating device can easily identify the identification substance 10. Figure 4c In addition, compared to the embodiment illustrated in FIG. 1, the sensor module of the aerosol generating device can easily identify the identification substance 10. Figure 4c In addition, compared to the embodiment illustrated in FIG. 1, the sensor module of the aerosol generating device can easily identify the identification substance 10.

[0172] Figure 5 is a perspective view of an aerosol generating article for explaining a disposition position of an identification substance.

[0173] Figure 5 The cigarette 5 illustrated in FIG. 5 can be at least one of the above-described aerosol generating articles, and thus the repeated explanation will be omitted below.

[0174] In addition, the cigarette 5 can incorporate at least one configuration or feature of the above-described embodiments unless technically obviously unfeasible. For example, Figure 5 The above-described embodiments are explained based on the identification substance 10 being disposed on the outer surface of the wrapping paper, but are not limited thereto, Figure 5 The identification substance 10 illustrated in FIG. 5 can also be disposed on the inner surface of the wrapping paper.

[0175] Referring to FIG. 6, Figure 5 The identification substance 10 can be disposed in a pattern in the circumferential direction of the cigarette 5, but can be disposed in only a partial region in the length direction of the cigarette 5. In this case, the sensor module of the aerosol generating device can be disposed at a predetermined position in the circumferential direction of the cigarette 5 to identify the identification substance 10, and thus the degree of freedom of the configuration structure of the sensor module can be improved.

[0176] In addition, compared to the embodiment in which the identification substance 10 is disposed in the entire region in the length direction of the wrapping paper, the use amount of the identification substance 10 can be reduced.

[0177] For example, the disposition region of the identification substance 10 can extend by about 1 mm to about 10 mm in the length direction of the cigarette 5. For example, the disposition region of the identification substance 10 can extend by about 2 mm to about 7 mm in the length direction of the cigarette 5.

[0178] Further, the cigarette 5 includes the tobacco rod 51 and the filter rod 52 aligned in sequence along the length direction of the cigarette 5, and the identification substance 10 can be disposed in an area extending from the boundary BL of the tobacco rod 51 and the filter rod 52 in a direction toward the filter rod 52.

[0179] The length from the lower end of the disposition area of the identification substance 10 to the boundary BL of the tobacco rod 51 and the filter rod 52 can be about 0 mm to about 5 mm. Within the above range, heat applied to the cigarette 5 can be prevented from being transferred to the identification substance 10. For example, the length from the lower end of the disposition area of the identification substance 10 to the boundary BL of the tobacco rod 51 and the filter rod 52 can be about 1 mm to about 3 mm.

[0180] Hereinafter, the separation preventing portion preventing the identification substance from being separated from the wrapper will be described with reference to the drawings in an embodiment in which the identification substance is disposed on the outer surface of the wrapper.

[0181] Figure 6a and Figure 6b is a view illustrating separation of the tobacco rod, the filter rod, and the wrapper in the aerosol generating article.

[0182] Referring to Figure 6a and Figure 6b , the cigarette 5 can include the identification substance 10, the separation preventing portion 20, the tobacco rod 51, the filter rod 52, and the wrapper 53. In Figure 6a and Figure 6b , at least one of the constituent elements of the cigarette 5 is the same as or similar to at least one of the constituent elements of the aerosol generating article described above, and thus repeated descriptions will be omitted hereinafter. Further, with reference to the following drawings and descriptions, of course, part of the constituent elements and structures can be replaced, added, or omitted within a range that can be easily understood by those skilled in the art.

[0183] The separation preventing portion 20 can perform a function of preventing the identification substance 10 from being detached from the wrapper 53. The separation preventing portion 20 can be disposed on the wrapper 53 to cover the disposition area of the identification substance 10. The separation preventing portion 20 can have a transparent property even though it covers the disposition area of the identification substance 10, so as not to shield light irradiated to the identification substance 10.

[0184] As illustrated in Figure 6b , the separation preventing portion 20 can change color at a temperature at which the tobacco rod 51 is heated. For example, the separation preventing portion 20 can be transparent before heating, and can include a thermochromic substance that changes color after being exposed to heat. Since the separation preventing portion 20 is disposed to cover the identification substance 10, the identification substance 10 can be shielded when the separation preventing portion 20 changes color. Accordingly, a user can easily determine whether the cigarette 5 is used or not by the naked eye. For example, the separation preventing portion 20 can change from a transparent color to an opaque brown color when heated at a temperature of 200℃ to 400℃.

[0185] The color change temperature of the separation preventing portion 20 can be higher than the activation temperature of the identification substance 10. In the present disclosure, the activation temperature of the identification substance 10 can be a critical temperature at which the identification substance 10 emits light having a wavelength different from that of the irradiation light. When the color change temperature of the separation preventing portion 20 is lower than the activation temperature of the identification substance 10, the separation preventing portion 20 can change color before the identification substance 10 emits light, thereby possibly blocking light irradiated to the identification substance 10, resulting in that the sensor module can not be able to identify the identification substance 10. According to an embodiment, since the color change temperature of the separation preventing portion 20 is higher than the activation temperature of the identification substance 10, the integrity of the operation of the sensor module to identify the identification substance 10 can be guaranteed.

[0186] In an embodiment, the area of the separation preventing portion 20 can be greater than the area of the arrangement region of the identification substance 10, and the separation preventing portion 20 can be arranged so that the arrangement region of the identification substance is not exposed. For example, the end portion of the separation preventing portion 20 can be maintained at a predetermined distance 20L from the end portion of the identification substance 10. The aforementioned predetermined distance 20L can be about 1 mm to about 10 mm.

[0187] When the predetermined distance 20L is less than about 1 mm, the possibility that the identification substance 10 is detached from the wrapping paper 53 can increase. In addition, when the predetermined distance 20L exceeds about 10 mm, the area of the separation preventing portion 20 is excessively large, and thus the separation preventing portion 20 can be accidentally heated.

[0188] In an embodiment, the separation preventing portion 20 can include a material having adhesion. The separation preventing portion 20 can include the same material as the OP varnish of the identification substance solution. For example, the separation preventing portion 20 can include one or more selected from the group consisting of nitrocellulose, polyamide, propyl acetate, isopropyl alcohol, ethyl acetate, and 1,2-cyclohexanedicarboxylic acid diisononyl ester (DINCH).

[0189] An aerosol generating device using the aerosol generating article described above is explained below with reference to the accompanying drawings.

[0190] Figure 7 is a schematic side view of an aerosol generating system according to an embodiment. In the present disclosure, the aerosol generating system can be used to refer to a system including an aerosol generating article and an aerosol generating device.

[0191] Referring to Figure 7The aerosol-generating device 1 can include an aerosol-generating device body 100, a control portion 110, a battery 120, a memory 130, a heater 140, and a sensor portion 150. However, the constituent elements of the aerosol-generating device 1 are not limited thereto, and according to embodiments, other constituent elements can be added, or at least one constituent element can be omitted.

[0192] Further, Figure 7 At least one of the constituent elements of the aerosol-generating system illustrated is the same as or similar to at least one of the constituent elements of the aerosol-generating system described above, and thus the repeated explanation is omitted below. Further, within the scope in which a person skilled in the art can easily understand with reference to the following drawings and explanations, of course, some of the constituent elements and structures can be replaced, added, or omitted.

[0193] The aerosol-generating device body 100 can form the overall appearance of the aerosol-generating device 1. The aerosol-generating device body 100 can accommodate the constituent elements of the aerosol-generating device 1.

[0194] A cavity 100a in which the cigarette 5 can be accommodated can be formed in the aerosol-generating device body 100. The cigarette 5 accommodated in the cavity 100a can be heated by the heater 140. The cavity 100a can be an elongated cavity, a coupling region, an insertion region, or a heating region in which the cigarette 5 is accommodated. The cavity 100a can have a shape corresponding to at least a partial region of the cigarette 5. For example, the cavity 100a can have a shape extending in one direction (for example, -Z direction) from an opening. The cigarette 5 can be inserted into the cavity 100a in a length direction through the opening.

[0195] The cigarette 5 accommodated in the cavity 100a can include the above-described identification portion ID. The identification portion ID can be disposed at at least a partial region of an outer circumferential surface of the cigarette 5. When the cigarette 5 is accommodated in the cavity 100a, the identification portion ID can be located inside the aerosol-generating device body 100.

[0196] The control portion 110 can control the overall operation of the aerosol-generating device 1. The control portion 110 can be implemented by an array of a plurality of logic gates, or by a combination of a general-purpose microcontroller and a memory in which a program executable in the microcontroller is stored, but is not limited thereto.

[0197] The control portion 110 can control the power supplied from the battery 120 to the heater 140. For example, the control portion 110 can control the amount of power supplied from the battery 120 to the heater 140 and the power supply time, so that the heater 140 is heated to a predetermined temperature or maintained at a designated temperature.

[0198] In an embodiment, the control portion 110 can receive a sensing result from the sensor portion 150. The memory 130 can be connected to the control portion 110, and can store executable instructions. The control portion 110 can control driving of the aerosol generating device 1 by executing the instructions stored in the memory 130.

[0199] In an embodiment, the control portion 110 receives a sensing result from the sensor portion 150, and identifies identification information of the cigarette 5 according to a light amount of light emitted from the identification portion ID by executing instructions related to the sensor portion 150 stored in the memory 130. For example, the identification information can be information about a kind of the cigarette 5, whether it is a genuine product, and / or a contained substance. The control portion 110 can control an operation of the aerosol generating device 1 according to the identified identification information.

[0200] Specifically, the control portion 110 can control power supply to the heater 140 based on the determined information of the cigarette 5. The control portion 110 can control driving of the heater 140 differently according to the identification information by executing instructions related to driving of the heater 140 stored in the memory 130.

[0201] The battery 120 can supply power required for an operation of the aerosol generating device 1. For example, the battery 120 can be electrically connected to the heater 140, and supply power for heating of the heater 140. In addition, the battery 120 can also supply power required for an operation of other constituent elements (e.g., the control portion 110, etc.) of the aerosol generating device 1. The battery 120 can be a rechargeable battery or a disposable battery. For example, the battery 120 can be a lithium polymer (LiPoly) battery, but the kind of the battery 120 is not limited thereto.

[0202] The memory 130 can be hardware for storing various data processed in the aerosol generating device 1, and can store data processed in the control portion 110 and data to be processed.

[0203] The memory 130 can have information related to appropriate temperature profiles and driving according to a kind of the cigarette 5, a kind of a contained substance, a content ratio of a substance, a content amount of a substance, and a degree of over-wetting, etc. The control portion 110 can perform an operation corresponding to the cigarette 5 based on the identification portion ID by executing instructions about driving of the heater 140 (e.g., a driving period, a driving intensity, etc.) acquired from the memory 130.

[0204] The heater 140 can obtain power from the battery 120, and heat at least a portion of the cigarette 5. For example, the heater 140 can be disposed outside a tobacco rod of the cigarette 5, and heat the tobacco rod.

[0205] The heater 140 is not limited to Figure 7The illustrated embodiment. That is, although Figure 7 The illustrated heater 140 is configured outside the cigarette 5, but the heater 140 can include a tubular heating element, a plate-shaped heating element, a needle-shaped heating element, or a rod-shaped heating element. At this time, the heater 140 can be inserted into the cigarette 5 to heat the inside of the cigarette 5.

[0206] The sensor portion 150 can be configured in the aerosol generating device body 100 to identify the identification portion ID of the cigarette 5. The sensor portion 150 can be configured at the periphery of the cavity 100a so as to be located at a position corresponding to the identification portion ID.

[0207] Although not illustrated in Figure 7 , the sensor portion 150 according to an embodiment can be of a light sensor package type including a light emitting portion and a light receiving portion, etc. Regarding the light sensor package, a detailed description will be given in Figures 24a to 32b .

[0208] The light emitting portion can emit light of a first wavelength toward the cavity 100a. For example, the light emitting portion can be configured of at least one light emitting diode that emits light of the first wavelength when a current flows therethrough.

[0209] In an embodiment, at least a portion of the light of the first wavelength emitted by the light emitting portion can be transmitted to the identification portion ID of the cigarette 5. The light of the first wavelength is excited at the identification portion ID, and the identification portion ID can emit light of a second wavelength different from the first wavelength. The wavelength and the amount of light, etc., of the light emitted from the identification portion ID can be determined according to the amount, the concentration, the kind, and / or the composition ratio of the identification portion ID.

[0210] The light receiving portion can receive the light emitted from the identification portion ID of the cigarette 5. For example, the light receiving portion can be configured of at least one light receiving diode that causes a current to flow when irradiated with light.

[0211] The light receiving portion can identify the identification information of the cigarette 5 by sensing the optical characteristics (e.g., the amount of light of the second wavelength) of the light emitted from the cigarette 5. The light receiving portion can provide the sensing result to the control portion 110.

[0212] Hereinafter, the light of the first wavelength emitted by the light emitting portion and the light of the second wavelength received by the light receiving portion will be described.

[0213] In an embodiment, the light of the first wavelength can be infrared rays, and the light of the second wavelength can be infrared rays having a wavelength different from that of the first wavelength. As an example, the first wavelength can be a wavelength in the range of 930 nm to 990 nm. The second wavelength can be a wavelength in the range of 1000 nm to 1020 nm. For example, the first wavelength can be a wavelength of 980 nm, and the second wavelength can be a wavelength of 1012 nm.

[0214] Accordingly, the sensor part 150 can recognize the identification information of the cigarette 5 without exposing the user's vision by using the light of the first wavelength composed of infrared rays and the light of the second wavelength.

[0215] In one embodiment, the light of the first wavelength can be ultraviolet rays, and the light of the second wavelength can be infrared rays. As an example, the first wavelength can be a wavelength in the range of 300 nm to 340 nm. The second wavelength can be a wavelength in the range of 1000 nm to 1020 nm. For example, the first wavelength can be a wavelength of 320 nm, and the second wavelength can be a wavelength of 1012 nm.

[0216] In one embodiment, the light of the first wavelength can be ultraviolet rays, and the light of the second wavelength can be visible rays. At this time, the light receiving part can be a color sensor. The color sensor can include an RGB (Red Green Blue) sensor or an XYZ light sensor for measuring, discriminating, or distinguishing the color of the identification mark. The RGB sensor includes light sources of three colors, and detects color information by reflecting light to an object. The XYZ light sensor includes a photo-digital converter, and can detect xy chromaticity coordinates according to the 1931 color space of the Commission Internationale de l'Eclairage (CIE).

[0217] As an example, the first wavelength can be a wavelength in the range of 340 nm to 375 nm, and the second wavelength can be a wavelength in the range of 380 nm to 780 nm. For example, the first wavelength can be a wavelength of 365 nm, and the second wavelength can be a wavelength of 613 nm to 627 nm (red light). As another example, the first wavelength can be a wavelength of 365 nm, and the second wavelength can be a wavelength of 540 nm to 551 nm (yellow light). In addition, the first wavelength can be a wavelength of 365 nm, and the second wavelength can be a wavelength of 513 nm to 537 nm (green light). In addition, the first wavelength can be a wavelength of 365 nm, and the second wavelength can be a wavelength of 437 nm to 477 nm (blue light).

[0218] As another example, the first wavelength can be a wavelength in the range of 250 nm to about 260 nm, and the second wavelength can be a wavelength in the range of 400 nm to about 750 nm. For example, the first wavelength can be a wavelength of 255 nm, and the second wavelength can be a wavelength of 580 nm (yellow light).

[0219] In an embodiment, the first wavelength can be a wavelength in the range of 600 nm to 900 nm, and the second wavelength can be a wavelength in the range of 1000 nm to 1020 nm. For example, the first wavelength can be a wavelength of 700 nm, and the second wavelength can be a wavelength of 1012 nm. At this time, the sensor portion 150 can include a near-infrared (NIR) sensor.

[0220] As described above, the sensor portion 150 can improve the recognition accuracy of the cigarette 5 by using different kinds of light (or light having a relatively large wavelength variation) of the first wavelength and the second wavelength.

[0221] For example, based on the sensing value of about 1012 nm received by the light receiving portion, the control portion 110 can determine that the cigarette 5 inserted into the aerosol generating device 1 is a first kind of cigarette 5. For another example, based on the sensing value of about 1012 nm received by the light receiving portion, the control portion 110 can also determine that the cigarette 5 inserted into the aerosol generating device 1 is a genuine product that is not counterfeit.

[0222] If it is determined that the kind of the cigarette 5 is a first kind of aerosol generating article, the control portion 110 can control the supply of power to the heater 140 based on a temperature profile corresponding to the first kind of aerosol generating article. For another example, if it is determined that the cigarette 5 is a counterfeit article, the control portion 110 can not supply power to the heater 140, or cut off the power being supplied.

[0223] When the kind of the cigarette 5 is sensed based on the sensing value sensed by the light receiving portion, the battery 120 can supply power to the heater 140 according to a temperature profile corresponding to the detected kind of cigarette 5. For another example, when it is determined that the cigarette 5 is a counterfeit article based on the sensing value sensed by the light receiving portion, the battery 120 can not supply power to the heater 140.

[0224] The light emitting portion and the light receiving portion can be disposed adjacent to each other in the cavity 100a. For example, the light emitting portion and the light receiving portion can be disposed at a predetermined distance apart in the z-axis direction along the direction in which the cavity 100a extends. For another example, the light emitting portion and the light receiving portion can be disposed at a predetermined distance apart in the x-axis direction along the direction in which the cavity 100a extends, in a manner of surrounding at least one region of the cavity 100a. At this time, the "at least one region of the cavity" can refer to a region corresponding to a region in which the recognition portion ID is disposed in the cigarette 5 when the cigarette 5 is accommodated in the cavity 100a.

[0225] Figure 8 is an aerosol-generating system having a heating method different from that of Figure 7 is an aerosol-generating system having a heating method different from that of

[0226] Referring to Figure 8The aerosol generating device 1 can include an aerosol generating device body 100, a control portion 110, a battery 120, a memory 130, a heater 140, and a sensor portion 150. Figure 8 At least one of the constituent elements of the aerosol generating system (for example, the sensor portion 150) illustrated in FIG. 1 can be the same as or similar to at least one of the constituent elements of the aerosol generating system of the related art, and thus overlapping descriptions will be omitted below. Figure 7 At least one of the constituent elements of the aerosol generating system (for example, the sensor portion 150) illustrated in FIG. 1 can be the same as or similar to at least one of the constituent elements of the aerosol generating system of the related art, and thus overlapping descriptions will be omitted below.

[0227] The aerosol generating device 1 can generate an aerosol by heating the cigarette 5 accommodated in the cavity 100a in an induction heating manner. The induction heating manner can refer to a manner in which an alternating magnetic field, which periodically changes direction, is applied to a magnetic body that heats by an external magnetic field to heat the magnetic body.

[0228] When the alternating magnetic field is applied to the magnetic body, energy loss caused by eddy current loss and hysteresis loss can occur in the magnetic body, and the lost energy can be released from the magnetic body in the form of heat energy. The greater the amplitude or frequency of the alternating magnetic field applied to the magnetic body, the more heat energy can be released from the magnetic body. The aerosol generating device 1 can heat the cigarette 5 by applying the alternating magnetic field to the magnetic body, causing the magnetic body to release heat energy, and transferring the heat energy released from the magnetic body to the cigarette 5.

[0229] To this end, the heater 140 can include a susceptor 140a and a coil 140b.

[0230] The susceptor 140a is a magnetic body that heats under a magnetic field. The susceptor 140a can be disposed inside the aerosol generating device body 100 and disposed in a manner of surrounding the cigarette 5 accommodated in the cavity 100a. In this case, the susceptor 140a can be integrally formed in a hollow cylindrical shape, but the shape thereof is not limited thereto.

[0231] In a modified embodiment, the susceptor 140a can also be disposed inside the cigarette 5 accommodated in the cavity 100a. In this case, the susceptor 140a can be included in the cigarette 5 in the shape of a piece, a sheet, or a strip, or the like.

[0232] At least a portion of the susceptor 140a can be formed of a ferromagnetic substance. For example, the susceptor 140a can include a metal or carbon. The susceptor 140a can include at least one of ferrite, a ferromagnetic alloy, stainless steel, and aluminum (Al). Also, the susceptor 140a can include at least one of ceramic such as graphite, molybdenum, silicon carbide, niobium, a nickel alloy, a metal film, zirconia, etc., a transition metal such as nickel (Ni), cobalt (Co), etc., a metalloid such as boron (B), phosphorus (P).

[0233] The coil 140b can apply an alternating magnetic field to the susceptor 140a, causing the susceptor 140a to heat. The coil 140b can be configured to surround the outside of the susceptor 140a. The battery 120 can include a battery cell that supplies direct current to the coil 140b and a conversion portion that converts the direct current supplied by the battery cell into alternating current that is supplied to the coil 140b.

[0234] The sensor portion 150 can identify the identification portion ID of the cigarette 5 accommodated in the cavity 100a, and the control portion 110 can control the supply of power to the coil 140b based on information of the cigarette 5.

[0235] Figure 9 is a flowchart of an aerosol generating system determining information of an aerosol generating article and controlling the supply of power to a heater according to an embodiment. Regarding Figure 9 The description of the aerosol generating system of the above-described embodiment is the same as or similar to the above-described embodiment, and thus repetitive description can be omitted.

[0236] Referring to Figure 9 The method of operation of the aerosol generating system according to an embodiment can include four steps.

[0237] First, in operation S100, the control portion of the aerosol generating device can irradiate light to the identification substance through the light emitting portion.

[0238] In an embodiment, when it is detected that the aerosol generating article is inserted, the control portion can irradiate light having a predetermined wavelength through the light emitting portion. For example, the aerosol generating device can include an inductive sensor, a capacitive sensor, or an insertion sensing sensor such as a pressure sensor, and when insertion of the aerosol generating article is sensed through the insertion sensing sensor, the control portion can irradiate light having a predetermined wavelength through the light emitting portion.

[0239] In another embodiment, when receiving a user input to the aerosol generating device, the control portion can irradiate light having a predetermined wavelength through the light emitting portion. For example, the aerosol generating device can include a physical button that enables a user to select a device state (e.g., power on / off), and when receiving a user input to the physical button, the control portion can irradiate light having a predetermined wavelength through the light emitting portion.

[0240] In an embodiment, the wavelength of the light irradiated through the light emitting portion can correspond to a first wavelength range. At this time, the first wavelength range can refer to a wavelength range of light capable of exciting the identification substance, and thus can be set in advance in a manner corresponding to the identification substance. For example, to identify an aerosol generating article containing an identification substance excited at a wavelength of about 365 nm, the first wavelength range can be set in advance to a range of about 340 nm to about 375 nm.

[0241] In an embodiment, the first wavelength range capable of exciting the identification substance can include at least one of a wavelength range of about 250 nm to about 260 nm, about 300 nm to about 340 nm, about 350 nm to about 390 nm, about 600 nm to about 900 nm, and about 930 nm to about 990 nm.

[0242] For example, when the first wavelength range includes a wavelength range of about 300 nm to about 340 nm, the control portion can irradiate ultraviolet light of about 320 nm to the identification substance of the aerosol generating article through the light emitting portion.

[0243] For another example, when the first wavelength range includes a wavelength range of about 340 nm to 375 nm, the control portion can irradiate ultraviolet light of about 365 nm to the identification substance of the aerosol generating article through the light emitting portion.

[0244] For yet another example, when the first wavelength range includes a wavelength range of about 930 nm to 990 nm, the control portion can also irradiate infrared light of about 980 nm to the identification substance of the aerosol generating article through the light emitting portion.

[0245] Subsequently, in act S200, the control portion can sense light emitted by the identification substance through the light receiving portion.

[0246] In an embodiment, the wavelength of the light sensed through the light receiving portion can correspond to a second wavelength range. At this time, the second wavelength range can refer to a wavelength range of light emitted by the identification substance excited due to the irradiation of the light of the first wavelength range. For example, when the identification substance is excited at a wavelength of about 320 nm, it can emit light in a range of about 1000 nm to about 1020 nm, and the control portion can determine the wavelength range of about 1000 nm to about 1020 nm obtained through the light receiving portion as the second wavelength range emitted by the identification substance.

[0247] In an embodiment, the control portion can sense the light emitted by the identification substance by receiving the ADC value from the light receiving portion. At this time, upon receiving the light from the identification substance, the light receiving portion can acquire an analog signal, and the "ADC value" can refer to a digital value converted from the analog signal acquired by the light receiving portion, which is recognizable by the control portion. For example, based on the ADC value received from the light receiving portion, the control portion can determine the wavelength range of the light emitted by the identification substance.

[0248] Subsequently, in action S300, the control portion can determine the information of the aerosol generating article based on the sensing value sensed by the light receiving portion. At this time, the information of the aerosol generating article can include the kind of the aerosol generating article, whether the aerosol generating article is counterfeit, or the like.

[0249] In an embodiment, the control portion can determine the information of the aerosol generating article based on different sensing values sensed due to the difference in the kind of the identification substance.

[0250] For example, the identification substance can include a first identification substance emitting light of about 1012 nm and a second identification substance emitting light of about 700 nm.

[0251] At this time, when the sensing value sensed by the light receiving portion corresponds to the wavelength value (about 1012 nm) emitted by the first identification substance, the control portion can determine that the aerosol generating article is a first kind of aerosol generating article containing the first identification substance.

[0252] Alternatively, when the sensing value sensed by the light receiving portion corresponds to the wavelength value (about 700 nm) emitted by the second identification substance, the control portion can determine that the aerosol generating article is a second kind of aerosol generating article containing the second identification substance.

[0253] The difference between the wavelength value emitted by the first identification substance and the wavelength value emitted by the second identification substance can be about 15 nm or more. If the difference between the wavelength value emitted by the first identification substance and the wavelength value emitted by the second identification substance is less than about 15 nm, the accuracy of the control portion in discriminating the kind of the identification substance can decrease. Herein, the wavelength value emitted by the first identification substance and the wavelength value emitted by the second identification substance can each refer to a main wavelength. For example, the difference between the wavelength value emitted by the first identification substance and the wavelength value emitted by the second identification substance can be about 30 nm or more, about 50 nm or more, or about 100 nm or more.

[0254] In an embodiment, the control portion can determine the information of the aerosol generating article based on different sensing values sensed due to the difference in the concentration of the identification substance.

[0255] For example, the identification substance can include the same kind of substance, but include an identification substance having a first concentration (for example: 20%) of a first concentration and an identification substance having a second concentration (for example: 30%) of a second concentration.

[0256] At this time, when the sensing value sensed by the light receiving part exceeds the first threshold value, the control part can determine that the aerosol generating article is the first kind of aerosol generating article including the identification substance of the first concentration.

[0257] Alternatively, when the sensing value sensed by the light receiving part exceeds a second threshold value greater than the first threshold value, the control part can determine that the aerosol generating article is the second kind of aerosol generating article including the identification substance of the second concentration.

[0258] Subsequently, in action S400, the control part 110 can control the supply of power to the heater based on the information of the aerosol generating article.

[0259] In an embodiment, the control part can control the supply of power to the heater based on the kind of the aerosol generating article. For example, when the kind of the aerosol generating article is determined to be the first kind of aerosol generating article, the control part can control the supply of power to the heater based on a first temperature profile preset for the first kind of aerosol generating article. For another example, when the kind of the aerosol generating article is determined to be the second kind of aerosol generating article, the control part can control the supply of power to the heater based on a second temperature profile preset for the second kind of aerosol generating article. At this time, the preset first and second temperature profiles can be different from each other.

[0260] In an embodiment, the control part can control the supply of power to the heater based on whether the aerosol generating article is counterfeit or not. For example, when the aerosol generating article is determined to be an authentic product, the control part can control the supply of power to the heater based on a temperature profile preset for the cigarette 5. For another example, when the aerosol generating article is determined to be a counterfeit product, the control part can not supply power to the heater or cut off the power being supplied.

[0261] Figure 10a is one example of a wavelength chart emitted from the first identification substance when a wavelength of a first wavelength range is irradiated. Figure 10b is one example of a wavelength chart emitted from the second identification substance when a wavelength of a first wavelength range is irradiated.

[0262] Referring to Figure 10a The first identification substance included in the aerosol generating article is excited by the light of the first wavelength range irradiated by the light emitting part, and thus can emit light having a predetermined wavelength range. At this time, the first wavelength range can be a wavelength range of about 300 nm to about 340 nm.

[0263] In an embodiment, the control portion of the aerosol generating device can determine the wavelength range 520 exceeding the threshold value 510 as the second wavelength range in a wavelength chart emitted by the first identification substance, that is, the first chart 500a. For example, the control portion can receive a sensing value corresponding to the wavelength range 520 through the light receiving portion, and the wavelength range 520 as the second wavelength range can be a wavelength range of about 1000 nm to about 1020 nm.

[0264] Referring to Figure 10b , the second identification substance contained in the aerosol generating article can be excited by the light of the first wavelength range irradiated by the light emitting portion, thereby emitting light having a predetermined wavelength range. At this time, the first wavelength range can be a wavelength range of about 930 nm to about 990 nm.

[0265] In an embodiment, the control portion 110 (refer to Figure 7 ) of the aerosol generating device can determine the wavelength range 520 exceeding the threshold value 510 as the second wavelength range in a wavelength chart emitted by the second identification substance, that is, the second chart 500b. For example, the control portion can receive a sensing value corresponding to the wavelength range 520 through the light receiving portion, and the wavelength range 520 as the second wavelength range can be a wavelength range of about 1000 nm to about 1020 nm.

[0266] For convenience of explanation, Figure 10a the first chart 500a and Figure 10b the second chart 500b are illustrated in the same form, but are not limited thereto. For example, in the first chart 500a of Figure 10a and the second chart 500b of Figure 10b , the wavelength range exceeding the threshold value 510 is partially similar, but the overall chart form can be different.

[0267] Figure 11a is one example of a wavelength chart emitted from the third identification substance when a wavelength of the first wavelength range is irradiated. Figure 11b is one example of a wavelength chart emitted from the third identification substance when a wavelength of the first wavelength range is irradiated.

[0268] Referring to Figure 11a , the third identification substance contained in the aerosol generating article can be excited by the light of the first wavelength range irradiated by the light emitting portion, thereby emitting light having a predetermined wavelength range. At this time, the first wavelength range can be a wavelength range of about 340 nm to about 375 nm.

[0269] In an embodiment, the control portion of the aerosol generating device can determine the wavelength range 620 exceeding the threshold 610 as the second wavelength range in a wavelength chart emitted by the third identification substance, that is, the third chart 600a. For example, the control portion can receive a sensing value corresponding to the wavelength range 620 through the light receiving portion, and the wavelength range 620 as the second wavelength range can be a part of a wavelength range of about 400 nm to about 750 nm.

[0270] For example, when the wavelength range 620 is about 450 nm to about 490 nm, the control portion can determine that the sensing value sensed through the light receiving portion corresponds to "blue", and can determine that the aerosol generating article in which the identification substance appears in "blue" is the first kind of aerosol generating article.

[0271] For another example, when the wavelength range 620 is about 490 nm to about 570 nm, the control portion can determine that the sensing value sensed through the light receiving portion corresponds to "green", and can determine that the aerosol generating article in which the identification substance appears in "green" is the second kind of aerosol generating article.

[0272] For still another example, when the wavelength range 620 is about 630 nm to about 750 nm, the control portion can determine that the sensing value sensed through the light receiving portion corresponds to "red", and can determine that the aerosol generating article in which the identification substance appears in "red" is the third kind of aerosol generating article.

[0273] Referring to Figure 11b , the third identification substance included in the aerosol generating article can be excited by the light of the first wavelength range irradiated by the light emitting portion, thereby emitting light having a predetermined wavelength range. At this time, the first wavelength range can be a wavelength range of about 250 nm to about 260 nm. That is, the third identification substance can be excited not only in a wavelength range of about 350 nm to about 390 nm, but also in a wavelength range of about 250 nm to about 260 nm.

[0274] In an embodiment, the control portion of the aerosol generating device can determine the wavelength range 620 exceeding the threshold 610 as the second wavelength range in a wavelength chart emitted by the third identification substance, that is, the fourth chart 600b. For example, the control portion can receive a sensing value corresponding to the wavelength range 620 through the light receiving portion, and the wavelength range 620 as the second wavelength range can be a part of a wavelength range of about 400 nm to about 750 nm.

[0275] For convenience of explanation, Figure 11a the third chart 600a and Figure 11b the fourth chart 600b are illustrated in the same form, but are not limited thereto. For example, in Figure 11a the third chart 600a and Figure 11bThe fourth graph 600b of FIG. 6A, the wavelength range exceeding the threshold 610 is partially similar, but the overall graph form can be different.

[0276] Figure 12 A flowchart of a specific other example of determining information of an aerosol generating article by an aerosol generating system according to an embodiment. Figure 12 A flowchart further specifying the actions of Figure 9 A flowchart further specifying the actions of Figure 12 In the description of

[0277] Referring to Figure 12 The action S200 can include an action S210 and an action S220.

[0278] First, the control portion of the aerosol generating device can stop irradiating the identification substance with light by the light emitting portion in the action S210 after irradiating the identification substance with light by the light emitting portion.

[0279] For example, the state of the identification substance can change from the ground state to the excited state when a first time elapses from the time when the light is emitted from the light emitting portion. At this time, the "first time" can refer to a time when no further change in the state of the substance occurs after the identification substance is excited by the light being absorbed. The control portion can irradiate the identification substance with light by the light emitting portion for the first time and stop irradiating the identification substance with light by the light emitting portion after the first time elapses.

[0280] Subsequently, in the action S220, the control portion can sense the light emitted from the identification substance by the light receiving portion when a second time elapses from the time when the light emitting portion stops irradiating the identification substance with light. At this time, the "second time" can refer to a time that elapses after the light originally irradiated by the light emitting portion is no longer sensed by the light receiving portion after the light emitting portion stops irradiating the light.

[0281] That is, the light receiving portion needs to mainly sense the light emitted by the identification substance, but since the light irradiated by the light emitting portion can be simultaneously sensed by the light receiving portion, a part of noise can be included in the sensing value.

[0282] However, according to the identification substance of the present disclosure, even if the light irradiated by the light emitting portion is blocked, it is possible to emit light (i.e., residual light) for a predetermined time. Therefore, in order for the light receiving portion to sense only the light emitted by the identification substance, the control portion can sense the light emitted by the identification substance by the light receiving portion after the second time elapses from the time when the light emitting portion stops irradiating the light.

[0283] In an embodiment, the control portion can sense the light emitted by the identification substance by the light receiving portion after a time of about 200 µs to about 2000 µs elapses from the time when the light emitting portion stops irradiating the identification substance with light.

[0284] For example, when the recognition substance is a first kind of substance that emits light for a long time even after the light irradiated from the light emitting section is blocked, or a substance of a first concentration, the control section can sense the light emitted from the recognition substance by the light receiving section after a lapse of a time of about 500 μs to about 2000 μs.

[0285] For another example, when the recognition substance is a second kind of substance that emits light for a short time even after the light irradiated from the light emitting section is blocked, or a substance of a second concentration lower than the first concentration, the control section can sense the light emitted from the recognition substance by the light receiving section after a lapse of a time of about 200 μs to about 500 μs. On the other hand, in another embodiment, the light receiving section can receive the light emitted from the recognition substance while the light emitting section emits light. Thereby, the time for the sensor section to recognize the recognition substance can be shortened.

[0286] Hitherto, the following embodiment has been described as an example: the recognition section ID (or the recognition substance 10) has a pattern (or a shape) formed at a prescribed distance from the boundary BL between the tobacco rod 51 and the filter rod 52 of the cigarette 5 in a direction toward the filter rod 52.

[0287] However, since the recognition substance 10 such as a marker has a characteristic of being excited by light of a specific first wavelength and emitting light of a specific second wavelength, the sensor section 150 can roughly well judge whether the cigarette 5 is counterfeit or not based on the change in the wavelength of the emitted light and the wavelength of the received light, however, in order to recognize the kind of the cigarette 5, it is necessary to base the correct wavelength value of the received light, and thus in a case where external noise is mixed in, it can not be possible to correctly recognize the kind of the cigarette 5. For example, the sensor section 150 can not be able to calculate an accurate sensing value due to the uneven state of the surface of the wrapping paper of the cigarette 5 or the surrounding environment. In particular, the sensor section 150 is very sensitive to the distance to the sensing object (for example: the recognition section ID), and thus it can be difficult to process these errors by a software algorithm alone. Therefore, it is necessary to propose a scheme capable of more accurately recognizing the kind of the cigarette 5 by changing the amount, concentration, and / or composition ratio of the recognition substance 10 included in the recognition section ID or changing the shape thereof.

[0288] Hereinafter, the following embodiment will be described in detail, in which the kind of the cigarette 5 can be accurately judged by deformation of the recognition section ID. Figures 13 to 23b

[0289] Figure 13 is a diagram for explaining a cigarette including a recognition section according to an embodiment. Figure 14a and Figure 14b are diagrams for explaining a recognition Figure 13 ​​A diagram of the sensor section for different types of cigarettes. Figures 15a to 15d It is a graph showing the individual sensing values ​​for multiple regions of the recognition unit.

[0290] at this time, Figure 14a and Figure 14b The aerosol generating device 1 shown is... Figure 7 The aerosol generating apparatus 1 shown is essentially the same, so the following mainly describes the differences and will omit repeated descriptions.

[0291] Reference Figure 13 According to one embodiment, the cigarette 5 includes a tobacco rod 51 and a filter rod 52, and may include an identification portion ID1 formed in a region extending from the boundary BL between the tobacco rod 51 and the filter rod 52 in a direction toward the filter rod 52.

[0292] According to one embodiment, the identification unit ID1 may include multiple regions (e.g., A1, A2, A3) with different concentrations of the identified substance.

[0293] For example, the identification unit ID1 may include a first region A1, a second region A2 and a third region A3 in a strip shape surrounding the outer peripheral surface of the cigarette 5, and the first region A1, the second region A2 and the third region A3 may be arranged adjacent to each other in a direction from the boundary BL toward the filter rod 52.

[0294] The identification substance may comprise substances of the same kind, including an identification substance with a first concentration (e.g., 7%), an identification substance with a second concentration (e.g., 20%), and an identification substance with a third concentration (e.g., 30%). The identification substance with the first concentration may be disposed in a first region A1, the identification substance with the second concentration may be disposed in a second region A2, and the identification substance with the third concentration may be disposed in a third region A3.

[0295] Reference Figure 14a and Figure 14b The aerosol generating device 1 may include: a body 100, including a cavity 100a for inserting a cigarette 5; a sensor unit 150 disposed around the cavity 100a and used to sense the identification unit ID1; and a control unit 110, which identifies the type of cigarette 5 based on the sensing value sensed by the sensor unit 150.

[0296] For example, when the cigarette 5 is fully inserted into the cavity 100a, the sensor unit 150 can be positioned at a position corresponding to the third region A3 of the cigarette 5. Therefore, during the process of inserting the cigarette 5 into the cavity 100a, the sensor unit 150 can sequentially sense the first region A1, the second region A2, and the third region A3 of the cigarette 5.

[0297] At this time, the sensor section 150 can be configured to determine a first concentration of the recognition substance having a first concentration (e.g., 7%) when the sensed value sensed by the light receiving section is within a first threshold range (e.g., 6% to 8%), and determine a second concentration of the recognition substance having a second concentration (e.g., 20%) when the sensed value sensed by the light receiving section is within a second threshold range (e.g., 19% to 21%). Likewise, the sensor section 150 can be configured to determine a third concentration of the recognition substance having a third concentration (e.g., 30%) when the sensed value sensed by the light receiving section is within a third threshold range (e.g., 29% to 31%).

[0298] Figures 15a to 15d is an exemplary chart for explaining a concentration pattern with respect to a plurality of regions. Thus, the number of cases of the concentration pattern is not limited to this. For example, when distinguishing whether the concentration difference between adjacent regions is a first-order difference (e.g., changing from a first concentration to a second concentration) or a second-order difference (e.g., changing from a first concentration to a third concentration), a pattern of more cases can be generated. Furthermore, even in a case where the number of regions included in the recognition section ID1 increases, the number of cases of the concentration pattern can increase.

[0299] Referring to Figure 15a , the first region Al has a first concentration, the second region A2 has a second concentration, and the third region A3 has a third concentration. At this time, the concentration intensity of the recognition substance decreases in the order of the third concentration (e.g., 30%), the second concentration (e.g., 20%), and the first concentration (e.g., 7%), and in the embodiment shown in Figure 15a , the sensor section 150 can determine that the first concentration pattern in which the sensed value has a right-upward tendency when the recognition section ID1 moves from the first region Al to the third region A3.

[0300] Furthermore, referring to Figure 15b , the first region Al can have a third concentration, the second region A2 can have a second concentration, and the third region A3 can have a first concentration. At this time, the concentration intensity of the recognition substance decreases in the order of the third concentration (e.g., 30%), the second concentration (e.g., 20%), and the first concentration (e.g., 7%), and in the embodiment shown in Figure 15b , the sensor section 150 can determine that the second concentration pattern in which the sensed value has a left-downward tendency when the recognition section ID1 moves from the first region Al to the third region A3.

[0301] Furthermore, referring to Figure 15c , the first region Al can have a first concentration, the second region A2 can have a third concentration, and the third region A3 can have a first concentration. At this time, in the concentration intensity of the recognition substance, since the third concentration (e.g., 30%) is greater than the first concentration (e.g., 7%), in the embodiment shown in Figure 15cIn the illustrated embodiment, the sensor portion 150 can determine a third concentration pattern in which the identification portion ID1 has a maximum value in the second region A2 of the upper fold shape.

[0302] Further, referring to Figure 15d , the first region A1 can have a third concentration, the second region A2 can have a first concentration, and the third region A3 can have a third concentration. At this time, in the concentration intensity of the identification substance, since the third concentration (for example, 30%) is greater than the first concentration (for example, 7%), in Figure 15d In the illustrated embodiment, the sensor portion 150 can determine a fourth concentration pattern in which the identification portion ID1 has a minimum value in the second region A2 of the lower fold shape.

[0303] The aerosol generating device 1 can further include a memory 130 including different concentration intensity change patterns for each kind of the cigarette 5. For example, the memory 130 can include a lookup table in which a concentration intensity change pattern is matched for each kind of the cigarette 5.

[0304] The control portion 110 can be configured to compare the respective sensing value intensity change patterns (for example, the first concentration pattern to the fourth concentration pattern) of the first region A1, the second region A2, and the third region A3 determined by the sensor portion 150 with the concentration intensity change patterns pre-stored in the memory 130 to determine the kind of the cigarette 5 inserted into the cavity 100a.

[0305] For example, the control portion 110 can be configured to determine the cigarette 5 as a first kind of aerosol generating article when the sensor portion 150 determines the sensing value of the identification portion ID1 as the first concentration pattern, as a second kind of aerosol generating article when the sensor portion 150 determines the sensing value of the identification portion ID1 as the second concentration pattern, as a third kind of aerosol generating article when the sensor portion 150 determines the sensing value of the identification portion ID1 as the third concentration pattern, and as a fourth kind of aerosol generating article when the sensor portion 150 determines the sensing value of the identification portion ID1 as the fourth concentration pattern.

[0306] As described above, when the aerosol generating device 1 senses the concentration pattern formed by the concentration difference of the identification substance included in the identification portion ID1 and identifies the kind of the cigarette 5 based on the sensed concentration pattern, an effect of preventing a malfunction due to a sensing error caused by a distance between the sensor portion 150 and the identification portion ID1 and a sensing error caused by unevenness of the surface of the wrapping paper of the cigarette 5 can be expected.

[0307] Figure 16 is a diagram for explaining a cigarette including an identification portion according to an embodiment. Figure 17a and Figure 17bIt is used to illustrate identification. Figure 16 A diagram of the sensor section for different types of cigarettes.

[0308] at this time, Figure 17a and Figure 17b The aerosol generating device 1 shown is... Figure 7 The aerosol generating apparatus 1 shown is essentially the same, so the following mainly describes the differences and will omit repeated descriptions.

[0309] Reference Figure 16 According to one embodiment, the cigarette 5 may include a tobacco stick 51 and a filter stick 52, and includes an identification portion ID2 formed in a region extending from the boundary BL between the tobacco stick 51 and the filter stick 52 in a direction toward the filter stick 52.

[0310] According to one embodiment, the identification unit ID2 may include multiple regions (e.g., A1, A2, A3, A4, A5) with different concentrations of the identified substance.

[0311] For example, the identification unit ID2 may include a strip-shaped first region A1, a second region A2, a third region A3, a fourth region A4, and a fifth region A5 surrounding the outer periphery of the cigarette 5, and the first region A1, the second region A2, the third region A3, the fourth region A4, and the fifth region A5 may be arranged adjacent to each other in a direction from the boundary BL toward the filter rod 52. Figure 16 Although the number of multiple regions is shown as 5 in the example, this is only an example and is not a limitation. Therefore, the number of multiple regions can be increased or decreased depending on the length of the cigarette 5 and the number of types of cigarette 5 that need to be identified.

[0312] The identified substances comprise the same type of substance, but the concentration of the identified substance in each of the multiple regions A1, A2, A3, A4, and A5 can be either a first concentration between a first threshold and a second threshold, or a second concentration between a third threshold and a fourth threshold. In this case, to clearly distinguish between the first and second concentrations, the difference between the second and third thresholds can be greater than the differences between the first and second thresholds, and also the differences between the third and fourth thresholds. For example, the first threshold could be 5%, and the second threshold could be 15%. Furthermore, the third threshold could be 30%, and the fourth threshold could be 40%.

[0313] When the identification part ID2 is formed, even if the adjacent regions among the plurality of regions A1, A2, A3, A4, and A5 are judged as the same concentration (for example, the first concentration), in order to distinguish the regions, the actual concentration values thereof can be set to be different. For example, even if the first region A1, the second region A2, and the third region A3 are all judged as the first concentration, the actual concentration value of the first region A1 can be 7%, the actual concentration value of the second region A2 can be 10%, and the actual concentration value of the third region A3 can be 13%.

[0314] Referring to Figure 17a and Figure 17b , the aerosol generating device 1 can include a body 100 including a cavity 100a into which the cigarette 5 is inserted, a sensor part 150 disposed at a periphery of the cavity 100a and configured to sense the identification part ID2, and a control part 110 configured to identify the kind of the cigarette 5 based on a sensing value sensed by the sensor part 150.

[0315] For example, when the cigarette 5 is completely inserted into the cavity 100a, the sensor part 150 can be disposed at a position corresponding to the fifth region A5 of the cigarette 5. Accordingly, during the process in which the cigarette 5 is inserted into the cavity 100a, the sensor part 150 can sequentially sense the first region A1, the second region A2, the third region A3, the fourth region A4, and the fifth region A5 of the cigarette 5.

[0316] The control part 110 according to an embodiment can be configured to convert the sequence of the sensing values of the first region A1 to the fifth region A5 into a binary code when one region of the identification part ID2 is judged as the first concentration, corresponding to "0", and when one region of the identification part ID2 is judged as the second concentration, corresponding to "1". That is, the identification part ID2 can function as a binary code part.

[0317] For example, when the actual concentration value of the first region A1 is 7%, the actual concentration value of the second region A2 is 10%, the actual concentration value of the third region A3 is 33%, the actual concentration value of the fourth region A4 is 7%, and the actual concentration value of the fifth region A5 is 33%, the control part 110 can convert the sensing value result of the identification part ID2 into a binary code having a value of 00101.

[0318] The aerosol generating device 1 can further include a memory 130 including different identification codes corresponding to the kind of each cigarette 5. For example, the memory 130 can include a look-up table in which an identification code is matched for the kind of each cigarette 5.

[0319] The control unit 110 can be configured to compare the binary code determined based on the sensing value of the sensor unit 150 with the identification code pre-stored in the memory 130 to determine the type of cigarette 5 inserted into the cavity 100a.

[0320] As shown above, when the aerosol generating device 1 calculates a binary code based on the concentration difference of the identification substance contained in the identification unit ID2, and identifies the type of cigarette 5 based on the calculated binary code, it is expected to prevent malfunctions caused by sensing errors due to the distance between the sensor unit 150 and the identification unit ID2, and sensing errors caused by the unevenness of the cigarette 5 packaging paper surface.

[0321] On the other hand, with the recent acceleration of personalization trends, various customized cigarettes are being produced in a diverse range to meet the preferences of different users. However, the types of markers that emit visible light when excited by ultraviolet light are limited. As mentioned above, markers can be excited by ultraviolet light and emit any one of red, green, blue, and yellow visible light. As shown above, there are limitations to using a limited number of markers to distinguish multiple types of cigarettes.

[0322] If a marker that emits visible light when excited by ultraviolet light is used to construct the identification unit, the following advantages are available: users can visually identify the type of cigarette with the naked eye; and because the wavelengths of each color are sufficiently separated, it has strong robustness to external noise. Therefore, research is needed to identify multiple types of cigarettes using a limited number of markers.

[0323] Figure 18 This is a diagram illustrating a cigarette including an identification section according to one embodiment. Figure 19a and Figure 19b It is used to illustrate identification. Figure 18 A diagram of the sensor section for different types of cigarettes.

[0324] at this time, Figure 19a and Figure 19b The aerosol generating device 1 shown is... Figure 7 The aerosol generating apparatus 1 shown is essentially the same, so the following mainly describes the differences and will omit repeated descriptions.

[0325] Reference Figure 18 According to one embodiment, the cigarette 5 may include a tobacco stick 51 and a filter stick 52, and includes an identification portion ID3 formed in a region extending from the boundary BL between the tobacco stick 51 and the filter stick 52 in a direction toward the filter stick 52.

[0326] According to one embodiment, the identification unit ID3 may include multiple regions (e.g., A1, A2) that identify different types of substances.Figure 18 In the embodiment, the identification portion ID3 is illustrated as including only two regions for convenience of explanation, but is not limited thereto, and the number of regions can be increased or decreased depending on the length of the cigarette 5 and the number of types of the cigarette 5 to be distinguished.

[0327] For example, the identification portion ID3 can include first and second regions A1 and A2 in the form of a band surrounding the outer circumferential surface of the cigarette 5, and the first and second regions A1 and A2 can be sequentially and adjacently disposed in a direction from the boundary BL toward the filter rod 52.

[0328] When the types of the identification substances included in the plurality of regions A1 and A2 are different from each other, the identification substances can respectively emit different second wavelengths of light by being excited by the first wavelength of light. For example, the first and second regions A1 and A2 of the identification portion ID3 according to an embodiment can be excited by ultraviolet light emitted by the sensor portion 150, and thus emit any one of red visible light, green visible light, blue visible light, and yellow visible light.

[0329] In Figure 18 In the embodiment, it is exemplarily illustrated that the first region A1 emits blue visible light when excited by ultraviolet light, and the second region A2 emits red visible light when excited by ultraviolet light. However, the first region A1 can emit any one of red visible light, green visible light, blue visible light, and yellow visible light when excited by ultraviolet light, and likewise, the second region A2 can also emit any one of red visible light, green visible light, blue visible light, and yellow visible light when excited by ultraviolet light. That is, the identification portion ID3 is divided into two regions, and when the light emitted by each region excited by ultraviolet light has four colors, the color pattern can have a number of 16 cases.

[0330] The identification portion ID3 can include an organic substance, and the organic substance can include one or more organic substances selected from the group consisting of quinazolinone-based compounds, thiophene-based compounds, sulfobenzoic acid-based compounds, and naphthylidine-based compounds.

[0331] Referring to Figure 19a and Figure 19b The aerosol-generating device 1 can include a body 100 including a cavity 100a into which the cigarette 5 is inserted, a sensor portion 150 disposed at a periphery of the cavity 100a and configured to sense the identification portion ID3, and a control portion 110 configured to identify the type of the cigarette 5 based on a sensed value sensed by the sensor portion 150.

[0332] For example, when the cigarette 5 is completely inserted into the cavity 100a, the sensor portion 150 can be disposed at a position corresponding to the second region A2 of the cigarette 5. Accordingly, the sensor portion 150 can sequentially sense the first and second regions A1 and A2 of the cigarette 5 during insertion of the cigarette 5 into the cavity 100a.

[0333] The aerosol-generating device 1 can further include a memory 130 including different color information corresponding to each kind of cigarette 5. For example, the memory 130 can include a lookup table in which color information is matched for each kind of cigarette 5.

[0334] The control portion 110 can be configured to compare the color pattern determined based on the sensor portion 150 with the color information pre-stored in the memory 130 to determine the kind of the cigarette 5 inserted into the cavity 100a.

[0335] Figure 20 is a diagram for explaining a cigarette including an identification portion according to an embodiment. Figure 21a and Figure 21b is a diagram for explaining a sensor portion identifying Figure 20 the kind of a cigarette. At this time, Figure 21a and Figure 21b The aerosol-generating device 1 shown in Figure 7 is substantially the same as the aerosol-generating device 1 shown in

[0336] Referring to Figure 20 , the cigarette 5 according to an embodiment can include a tobacco rod 51 and a filter rod 52, and include an identification portion ID2 formed in a region extending in a direction from a boundary BL of the tobacco rod 51 and the filter rod 52 toward the filter rod 52.

[0337] In the identification portion ID4 according to an embodiment, the band pattern BP including the first identification substance and the grid pattern GP including the second identification substance can be formed to overlap in a thickness direction.

[0338] When the kind of the first identification substance included in the band pattern BP and the kind of the second identification substance included in the grid pattern GP are different from each other, different second wavelengths of light can be respectively emitted by being excited by the same first wavelength of light. For example, the band pattern BP and the grid pattern GP of the identification portion ID4 according to an embodiment can be excited by ultraviolet light emitted by the sensor portion 150, thereby emitting any one of red visible light, green visible light, blue visible light, and yellow visible light.

[0339] For example, the band pattern BP can emit blue visible light when excited by ultraviolet light, and the grid pattern GP can emit red visible light when excited by ultraviolet light. However, it is not limited thereto, and the band pattern BP can emit any one of red visible light, green visible light, blue visible light, and yellow visible light when excited by ultraviolet light, and likewise, the grid pattern GP can also emit any one of red visible light, green visible light, blue visible light, and yellow visible light when excited by ultraviolet light.

[0340] The identification portion ID 4 can include an organic material, which can include one or more organic materials selected from the group consisting of quinazolinone-based compounds, thiophene-based compounds, sulfobenzoic acid-based compounds, and naphthylidine-based compounds.

[0341] Referring to Figure 21a and Figure 21b , the aerosol generating device 1 can include a body 100 including a cavity 100a into which the cigarette 5 is inserted, a sensor portion 150 disposed at a periphery of the cavity 100a and configured to sense the identification portion ID 4, and a control portion 110 configured to identify a kind of the cigarette 5 based on a sensed value sensed by the sensor portion 150.

[0342] At this time, the light emitting portion of the sensor portion 150 can include an ultraviolet light emitting diode, and the light receiving portion of the sensor portion 150 can include an RGB optical diode.

[0343] For example, when the cigarette 5 is completely inserted into the cavity 100a, the sensor portion 150 can be disposed at a position corresponding to the identification portion ID 4 of the cigarette 5. Accordingly, after the cigarette 5 is inserted into the cavity 100a, the sensor portion 150 can simultaneously sense the band pattern BP and the grid pattern GP of the identification portion ID 4.

[0344] The aerosol generating device 1 can further include a memory 130 including different color information corresponding to each kind of the cigarette 5. For example, the memory 130 can include a look-up table in which color information is matched for each kind of the cigarette 5.

[0345] The control portion 110 can be configured to compare color information of the identification portion ID 4 determined based on the sensor portion 150 with color information pre-stored in the memory 130 to determine a kind of the cigarette 5 inserted into the cavity 100a. At this time, the color information of the identification portion ID 4 can be a mixed color of a color of visible light emitted by the first identification substance of the band pattern BP and a color of visible light emitted by the second identification substance of the grid pattern GP. In the above example, if the band pattern BP emits blue visible light when excited by ultraviolet light and the grid pattern GP emits red visible light when excited by ultraviolet light, the color information of the identification portion ID 4 can be purple.

[0346] Figure 22 is a diagram for explaining a cigarette including an identification portion according to an embodiment. Figure 23a and Figure 23b are diagrams for explaining a sensor portion identifying Figure 22 a kind of a cigarette. At this time, Figure 23a and Figure 23b the aerosol generating device 1 shown in FIGS.Figure 7 The only difference of the illustrated aerosol generating device 1 is that the cavity 100a is rotated around a rotation axis coinciding with the central axis of the cigarette 5 (for example, +z and -z directions), and the rest of the structure is substantially the same. Hereinafter, the difference part will be mainly described, and the repeated description will be omitted.

[0347] Referring to Figure 22 The cigarette 5 according to an embodiment can include a tobacco rod 51 and a filter rod 52, and include an identification part ID5 formed in an area extending in a direction from a boundary BL of the tobacco rod 51 and the filter rod 52 toward the filter rod 52.

[0348] The identification part ID5 according to an embodiment is in a band shape around the outer circumferential surface of the cigarette 5 as a whole, and can include a plurality of areas (for example, A1, A2, A3, A4) continuously arranged in the circumferential direction (for example, +x and -x directions) of the cigarette 5.

[0349] When the types of the identification substances each contained in the plurality of areas A1, A2, A3, A4 are different from each other, different second wavelengths of light can be respectively emitted by being excited by the same first wavelength of light. For example, each of the plurality of areas A1, A2, A3, A4 of the identification part ID5 according to an embodiment can be excited by the ultraviolet light emitted by the sensor part 150, and emit any one of red visible light, green visible light, blue visible light, and yellow visible light.

[0350] For example, the first area A1 can emit red visible light when excited by ultraviolet light, the second area A2 can emit green visible light when excited by ultraviolet light, the third area A3 can emit blue visible light when excited by ultraviolet light, and the fourth area A4 can emit yellow visible light when excited by ultraviolet light.

[0351] Each of the plurality of areas A1, A2, A3, A4 of the identification part ID5 can contain an organic substance, and the organic substance can contain one or more organic substances selected from the group consisting of quinazolinone-based compounds, thiophene-based compounds, sulfobenzoic acid-based compounds, and naphthylidine-based compounds.

[0352] Referring to Figure 23a and Figure 23b The aerosol generating device 1 can include a body 100 including a cavity 100a into which the cigarette 5 is inserted, a sensor part 150 arranged at the periphery of the cavity 100a and configured to sense the identification part ID5, and a control part 110 configured to identify the type of the cigarette 5 based on a sensed value sensed by the sensor part 150.

[0353] The aerosol-generating device 1 can further include a driving device 160 for generating a driving force to rotate the cavity 100a. For example, the driving device 160 is configured inside the body 100, and can be a motor that operates by an electric signal. When an electric signal from the control portion 110 is applied to the motor of the driving device 160, the shaft of the motor performs a rotational motion, and the cavity 100a can be rotated by the driving force of the motor.

[0354] Embodiments of rotating the cavity 100a are not limited to Figure 23a and Figure 23b For example, the driving device 160 can further include various power transmission elements such as gears, belts, sprockets, etc.

[0355] The light emitting portion of the sensor portion 150 can include an ultraviolet light emitting diode, and the light receiving portion of the sensor portion 150 can include an RGB optical diode.

[0356] When the cigarette 5 is completely inserted into the cavity 100a, the sensor portion 150 can be configured at a position corresponding to the identification portion ID5 of the cigarette 5. Accordingly, after the cigarette 5 is inserted into the cavity 100a, the sensor portion 150 can sequentially sense a plurality of regions (e.g., A1, A2, A3, A4) of the identification portion ID5 during one rotation of the cavity 100a in one direction about the rotation axis. Accordingly, the sensor portion 150 can sense color pattern information of visible light emitted when the plurality of regions (e.g., A1, A2, A3, A4) are excited by ultraviolet light.

[0357] Although not explicitly shown in Figure 22 , the identification portion ID5 according to an embodiment can further include an additional region (not shown) between the plurality of regions (e.g., A1, A2, A3, A4). The identification substance contained in the additional region can emit light (e.g., infrared) of a non-visible wavelength when excited by ultraviolet light. Since it is not known which region (e.g., A1, A2, A3, A4) of the identification portion ID5 is first correspondingly configured at the sensor portion 150 when the cigarette 5 is inserted into the cavity 100a, the additional region that emits infrared light when excited by ultraviolet light can be provided to define a color pattern with the region emitting infrared light as a reference point.

[0358] For example, the cigarette 5 has a circular cross-section, and thus the red-green-blue-yellow pattern, the green-blue-yellow-red pattern, the blue-yellow-red-green pattern, and the yellow-red-green-blue pattern can be recognized as the same color pattern depending on the position of the region of the identification portion ID 5 that the sensor portion 150 first senses. Thus, when the color pattern is defined with the region emitting infrared light as a reference, the infrared-red-green-blue-yellow pattern, the infrared-green-blue-yellow-red pattern, the infrared-blue-yellow-red-green pattern, and the infrared-yellow-red-green-blue pattern are formed, and thus the color pattern can be distinguished regardless of which region of the identification portion ID 5 that the sensor portion 150 first senses. In other words, the number of types of color patterns can be further ensured.

[0359] The aerosol generating device 1 can further include a memory 130 including different color pattern information corresponding to each type of cigarette 5. For example, the memory 130 can include a lookup table in which color pattern information is matched for each type of cigarette 5.

[0360] The control portion 110 can be configured to compare the color pattern information of the identification portion ID 5 determined based on the sensor portion 150 with the color pattern information pre-stored in the memory 130 to determine the type of the cigarette 5 inserted into the cavity 100a.

[0361] On the other hand, the aerosol generating device 1 can cause the sensing value of the sensor portion 150 to deteriorate due to various reasons (e.g., external light interference, occurrence of crosstalk, inflow of contaminant, etc.), or can cause a limitation on the performance of the sensor portion 150 (e.g., a decrease in the amount of light emitted by the light emitting portion, etc.) due to heat generated by the heater 140 for heating the cigarette 5, etc. In addition, since the aerosol generating device 1 belongs to a small electronic product, the assembly space of the electronic components is limited, and it is inevitable that a power consumption problem due to the capacity limitation of the battery 120 can occur.

[0362] To overcome the above problems, the sensor portion 150 can be basically formed in a sensor package type. Hereinafter, an embodiment of a light sensor package will be specifically described. Figures 24a to 32b , an embodiment of a light sensor package will be specifically described.

[0363] Figure 24a is a diagram for explaining an aerosol generating system according to an embodiment. Figure 24b is a top view of a light sensor package according to an embodiment, Figure 24c is a cross-sectional view of the light sensor package taken along the I-I' line of Figure 24b . Figure 24d is a diagram for explaining a sensing operation of a light sensor package according to an embodiment.

[0364] Referring toFigures 24a to 24d According to an embodiment, an aerosol generating system can include a cigarette 5 including an identification portion ID that emits light of a second wavelength different from a first wavelength when excited by light of the first wavelength, and an aerosol generating device 1.

[0365] The aerosol generating device 1 can include a body 100 including a cavity 100a into which the cigarette 5 is inserted, a light sensor package PKG disposed at a periphery of the cavity 100a and configured to sense the identification portion ID, and a control portion 110 configured to identify whether the cigarette 5 is counterfeit and a type of the cigarette 5 based on a sensed value sensed by the light sensor package PKG. Figure 24a The aerosol generating device 1 illustrated in FIG. 1A can correspond to the aerosol generating device 1 illustrated in Figure 7 and Figure 8 The aerosol generating device 1 illustrated in FIG. 1A can correspond to the aerosol generating device 1 illustrated in

[0366] According to an embodiment, the light sensor package PKG can include a package substrate SUB, a light emitting portion LU, a semiconductor chip SC, a light receiving portion PU, and a molding member ENC.

[0367] In an embodiment, in the package substrate SUB, a first element PE1 and a second element PE2 can be formed on a first surface S1 (e.g., a +Z-directional surface), and a substrate terminal TE can be formed on a second surface S2 (e.g., a -Z-directional surface) opposite the first surface S1.

[0368] In an embodiment, the first surface S1 can be a surface of the light sensor package PKG facing the identification portion ID of the cigarette 5. The substrate terminal TE can be electrically and / or physically connected to the aerosol generating device 1 of the present disclosure in which the light sensor package PKG is mounted.

[0369] The identification substance 10 can be excited when absorbing light of a predetermined wavelength range, and at this time, the "substance is excited" can mean that a state of the substance is changed from a ground state to an excited state. Subsequently, the light emitting substance can emit light of the predetermined wavelength range in a process in which the state of the identification substance 10 is changed from the excited state to the ground state.

[0370] In an embodiment, the identification substance 10 can be excited by light irradiated by the light emitting portion LU and can emit light of a wavelength range different from the wavelength range of the irradiated light. For example, the identification substance 10 can be excited by light of a first wavelength range irradiated by the light emitting portion LU and can emit light of a second wavelength range different from the first wavelength range.

[0371] For example, the recognition substance 10 can be a first light-emitting substance that emits light in a second wavelength range of about 400 nm to about 750 nm when excited by light in a first wavelength range of about 350 nm to about 390 nm. Accordingly, the light-emitting unit LU can irradiate ultraviolet light of about 365 nm to the first light-emitting substance, and the light-receiving unit PU can sense visible light (i.e., red light) of 700 nm emitted by the first light-emitting substance.

[0372] In an embodiment, the light-emitting unit LU can be composed of at least one light-emitting diode that emits light (L) of the first wavelength when a current flows therethrough. For example, Figures 24a to 24c Both of the light-emitting units LU shown can be ultraviolet light-emitting diodes. Accordingly, the optical sensor package PKG can provide a light-emitting amount sufficient to sense the recognition unit ID of the cigarette 5.

[0373] In an embodiment, the semiconductor chip SC can be composed of an application specific integrated circuit (ASIC) for controlling the overall operation of the optical sensor package PKG.

[0374] The semiconductor chip SC according to an embodiment includes a signal processing unit electrically connected to the light-receiving unit PU, and the signal processing unit can include an analog-to-digital converter (not shown) for converting a sensed value in the form of an analog signal from the light-receiving unit PU into a digital signal.

[0375] The aerosol-generating device 1 according to an embodiment can include a first flexible printed circuit board FPCB1 electrically connected to the heater 140 and a second flexible printed circuit board FPCB2 electrically connected to the optical sensor package PKG. At this time, the first flexible printed circuit board FPCB1 and the second flexible printed circuit board FPCB2 can be disposed adjacent to each other in an electrically insulated state. Accordingly, if an analog signal sensed by the optical sensor package PKG, i.e., a sensed value, is transmitted to the control unit 110 for processing via the second flexible printed circuit board FPCB2, there can be a problem in that noise is introduced due to the heater 140 (particularly, a heater of an induction heating type) and the second flexible printed circuit board FPCB1 disposed in the periphery.

[0376] To minimize such a problem, the optical sensor package PKG can perform signal processing on the sensed sensed value through the semiconductor chip SC, convert a result value thereof into a digital signal, and transmit the digital signal to the control unit 110.

[0377] The control unit 110 can determine whether the cigarette 5 is counterfeit and the type of the cigarette 5 based on the digital signal generated by the signal processing unit.

[0378] In an embodiment, the light-receiving portion PU can be constituted by at least one light-receiving diode through which a current flows when receiving light (L') of a second wavelength different from the light (L) of the first wavelength. For example, Figures 24a to 24d The illustrated light-receiving portion PU can be an RGB sensing sensor. The RGB sensing sensor can internally include a first light diode PU1 for sensing red light, a second light diode PU2 for sensing green light, and a third light diode PU3 for sensing blue light. The RGB sensing sensor can sense a color of the light (L') of the second wavelength based on a proportion of the amount of light each of the first light diode PU1, the second light diode PU2, and the third light diode PU3 receives.

[0379] In an embodiment, the light sensor package PKG can include a first element PE1, a second element PE2, and a first conductive member W1.

[0380] In an embodiment, the first element PE1 and the second element PE2 can be formed on the first surface S1. The first element PE1 can be connected to the light-emitting portion LU constituted by a light-emitting diode, and the second element PE2 can be connected to the semiconductor chip SC.

[0381] In an embodiment, the first conductive member W1 can electrically connect the first element PE1 and the light-emitting portion LU. For example, the first element PE1 can be constituted by two terminals including a cathode terminal and an anode terminal. The light-emitting portion LU can be directly bonded to either of the two terminals. The first conductive member W1 can connect the light-emitting portion LU and the other of the two terminals.

[0382] Further, the solder ball SD can electrically connect the second element PE2 and the semiconductor chip SC. For example, the second element PE2 can be constituted by a plurality of terminals corresponding to the pad electrodes formed on the back surface of the semiconductor chip SC. The semiconductor chip SC can configure the solder ball SD between the pad electrodes of the semiconductor chip SC and the plurality of electrodes of the second element PE2, and be bonded to the second element PE2 through a reflow process.

[0383] In an embodiment, the first element PE1 and the second element PE2 can be configured adjacent to each other on the first surface S1. Thereby, the light-emitting portion LU and the semiconductor chip SC can be configured adjacent to each other on the first surface S1 of the package substrate SUB.

[0384] In an embodiment, the light-receiving portion PU can be configured on the semiconductor chip SC. For example, the light-receiving portion PU can be integrally manufactured at the time of manufacturing the semiconductor chip SC. In Figure 24aThe light-receiving portion PU is disposed on the left upper end of the semiconductor chip SC, and the area of the light-receiving portion PU accounts for about 1 / 4 of the semiconductor chip SC, as shown in the middle. However, this is merely exemplary and is not limited thereto. That is, the size and disposition position of the light-receiving portion PU can be variously changed according to the requirements of a customer.

[0385] According to an embodiment, a height H1 from the first surface S1 (or the upper surface) of the package substrate SUB to the upper surface of the semiconductor chip SC can be higher than a height H2 from the first surface S1 (or the upper surface) of the package substrate SUB to the upper surface of the light-emitting portion LU. For example, the height H1 from the first surface S1 (or the upper surface) of the package substrate SUB to the upper surface of the semiconductor chip SC can be about 610 μm, and the height H2 from the first surface S1 (or the upper surface) of the package substrate SUB to the upper surface of the light-emitting portion LU can be about 150 μm.

[0386] As described above, when the height H1 from the first surface S1 (or the upper surface) of the package substrate SUB to the upper surface of the semiconductor chip SC is higher than the height H2 from the first surface S1 (or the upper surface) of the package substrate SUB to the upper surface of the light-emitting portion LU, since the light-receiving portion PU is disposed on the semiconductor chip SC, it is possible to prevent the light (L) emitted from the light-emitting portion LU from being directly incident on the light-receiving portion PU without passing through the identification portion ID of the cigarette 5. That is, the semiconductor chip SC can function as a partition wall in terms of shielding the light radiated from the light-emitting portion LU.

[0387] Thus, the optical sensor package PKG of the present application can expect to improve the sensing sensitivity of the optical sensor package PKG by preventing the light (L) emitted from the light-emitting portion LU from being directly incident on the light-receiving portion PU, thereby causing a crosstalk phenomenon.

[0388] In an embodiment, the molding member ENC can be disposed on the first surface S1 of the package substrate SUB. The molding member ENC can protect the first surface S1 of the package substrate SUB and other constituent elements (e.g., the light-emitting portion LU, the semiconductor chip SC, and the light-receiving portion PU) mounted to the first surface S1. The molding member ENC can be made of a non-conductive material. The molding member ENC can reduce or prevent the first surface S1 of the package substrate SUB and other constituent elements mounted to the first surface S1 from being electrically disconnected or unnecessarily short-circuited.

[0389] In an embodiment, the molding member ENC can be formed on the first surface S1 of the package substrate SUB to surround the light-emitting portion LU, the semiconductor chip SC, and the light-receiving portion PU.

[0390] In an embodiment, the molding member ENC can be made of a light-transmissive substance. For example, the molding member ENC can be a transparent molding compound (CMC). The molding member ENC can guide the light emitted by the light emitting portion LU to the sensing object of the light sensor package PKG, i.e., the identification portion ID of the cigarette 5.

[0391] In an embodiment, the molding member ENC can connect the regions respectively surrounding the light emitting portion LU, the semiconductor chip SC, and the light receiving portion PU to form a single structure. The molding member ENC can be substantially uniformly coated and cured on the first surface S1 of the package substrate SUB. The molding member ENC formed of a single structure can improve the manufacturing efficiency of the light sensor package PKG.

[0392] Figure 25a is a plan view of a light sensor package according to an embodiment, Figure 25b is a cross-sectional view of the light sensor package taken along Figure 25a the line II-II' of

[0393] Figure 25a and Figure 25b The light sensor package PKG shown in Figures 24a to 24d differs from the light sensor package PKG shown in

[0394] Referring to Figure 25a and Figure 25b , the light sensor package PKG according to an embodiment can include a package substrate SUB, a light emitting portion LU, a semiconductor chip SC, a light receiving portion PU, and a molding member ENC.

[0395] The identification substance 10 can be included on a surface of the cigarette 5.

[0396] The identification substance 10 can be excited when absorbing light in a predetermined wavelength range, and at this time, the "substance is excited" can mean that the state of the substance is changed from a ground state to an excited state. Subsequently, in a process in which the state of the identification substance 10 is changed from the excited state to the ground state, the light emitting substance can emit light in the predetermined wavelength range.

[0397] In an embodiment, the identification substance 10 can be excited by light irradiated by the light emitting portion LU and can emit light in a wavelength range different from the wavelength range of the irradiated light. For example, the identification substance 10 can be excited by light in a first wavelength range irradiated by the light emitting portion LU and can emit light in a second wavelength range different from the first wavelength range.

[0398] For example, the recognition substance 10 can be a first luminescent substance that emits light in a second wavelength range of about 400 nm to about 750 nm when excited by light in a first wavelength range of about 350 nm to about 390 nm. Accordingly, the light emitting portion LU can irradiate the first luminescent substance with ultraviolet light of about 365 nm, and the light receiving portion PU_1 can sense visible light (i.e., red light) of 700 nm emitted by the first luminescent substance.

[0399] For another example, the recognition substance 10 can be a second luminescent substance that emits light in a second wavelength range of about 1000 nm to about 1020 nm when excited by light in a first wavelength range of about 300 nm to about 340 nm. Accordingly, the light emitting portion LU can irradiate the second luminescent substance with ultraviolet light of about 325 nm, and the light receiving portion PU_1 can sense infrared light of 1012 nm emitted by the second luminescent substance.

[0400] For yet another example, the recognition substance 10 can be a third luminescent substance that emits light in a second wavelength range of about 1000 nm to about 1020 nm when excited by light in a first wavelength range of about 930 nm to about 990 nm. Accordingly, the light emitting portion LU can irradiate the third luminescent substance with infrared light of about 980 nm, and the light receiving portion PU_1 can sense infrared light of about 1012 nm emitted by the third luminescent substance.

[0401] Figure 25a And Figure 25b The embodiment illustrated can include a light emitting portion LU composed of an ultraviolet light emitting diode and a light emitting portion LU_1 composed of an infrared light emitting diode.

[0402] In an embodiment, the semiconductor chip SC can be composed of an application specific integrated circuit for controlling the overall operation of the optical sensor package PKG.

[0403] In an embodiment, the light receiving portion PU_1 can be composed of at least one light receiving diode through which a current flows when receiving light (L’) of a second wavelength different from light (L) of a first wavelength. For example, Figure 25a And Figure 25b The light receiving portion PU_1 illustrated can be an RGB sensing sensor. The RGB sensing sensor can internally include a first light diode PU1 for sensing red light, a second light diode PU2 for sensing green light, and a third light diode PU3 for sensing blue light. In addition, the light receiving portion PU_1 can further include an infrared light receiving diode PU4 capable of receiving light of an infrared wavelength (i.e., about 1000 nm to about 1020 nm).

[0404] Therefore, when the identifying substance contained in the cigarette 5 is the first luminescent substance, the light emitted by the luminescent part LU, which is composed of an ultraviolet light-emitting diode, can be sensed by the RGB sensing sensor (e.g., PU1, PU2, PU3) of the light-receiving part PU_1. When the identifying substance is the second luminescent substance, the light emitted by the luminescent part LU, which is composed of an ultraviolet light-emitting diode, can be sensed by the infrared light-receiving diode PU4 of the light-receiving part PU_1.

[0405] Furthermore, when the identifying substance contained in the cigarette 5 is a third luminescent substance, the infrared light emitted by the luminescent part LU_1, which is composed of an infrared light-emitting diode, can be excited into infrared light of the second wavelength and sensed by the infrared light-receiving diode PU4 of the light-receiving part PU_1.

[0406] On the other hand, the infrared light emitted by the light-emitting part LU_1, which is composed of an infrared light-emitting diode, can be directly sensed by the infrared light-receiving diode PU4 of the light-receiving part PU_1 with its original first wavelength infrared light.

[0407] In one embodiment, the optical sensor package PKG may include a first conductive member W1_1. In one embodiment, the first conductive member W1_1 can electrically connect a first element PE1_1 and a light-emitting part LU_1.

[0408] In one embodiment, the light-receiving part PU_1 may be disposed on the semiconductor chip SC. Furthermore, the height H1 from the first surface S1 (or upper surface) of the packaging substrate SUB to the upper surface of the semiconductor chip SC may be higher than the height H2 from the first surface S1 (or upper surface) of the packaging substrate SUB to the upper surface of the light-emitting part LU.

[0409] With Pass Figures 24a to 24d The situation is the same as described above. Figure 25a and Figure 25b In the optical sensor package PKG shown, the semiconductor chip SC has a partition function, which can prevent crosstalk and thus improve the sensing sensitivity of the optical sensor package PKG.

[0410] Figure 26a This is a top view of a light sensor package according to one embodiment. Figure 26b It is along Figure 26a A cross-sectional view of the optical sensor package taken from line III-III'.

[0411] Figure 26a and Figure 26b The optical sensor package PKG shown is Figures 24a to 24dThe light sensor package PKG shown in FIG. 1 is different from the light sensor package PKG shown in FIG. 2 in that the former includes an infrared light diode instead of an RGB sensing sensor, and the rest of the configurations are substantially the same. Hereinafter, the configurations that are different will be mainly described, and the repeated description of the same configurations will be omitted.

[0412] Referring to Figure 26a and Figure 26b , the light sensor package PKG according to an embodiment can include a package substrate SUB, a light emitting part LU, a semiconductor chip SC, a light receiving part PU_2, and a molding member ENC.

[0413] An identification substance 10 can be included on a surface of a cigarette 5.

[0414] The identification substance 10 can be excited when absorbing light of a predetermined wavelength range, and at this time, the "substance is excited" can mean that the state of the substance is changed from a ground state to an excited state. Subsequently, the light emitting substance can emit light of a predetermined wavelength range in a process in which the state of the identification substance 10 is changed from the excited state to the ground state.

[0415] In an embodiment, the identification substance 10 can be excited by light irradiated from the light emitting part LU and can emit light of a wavelength range different from the wavelength range of the irradiated light. For example, the identification substance 10 can be excited by light of a first wavelength range irradiated from the light emitting part LU and can emit light of a second wavelength range different from the first wavelength range.

[0416] For example, the identification substance 10 can be a second light emitting substance that emits light of a second wavelength range of about 1000 nm to about 1020 nm when excited by light of a first wavelength range of about 300 nm to about 340 nm. Accordingly, the light emitting part LU can irradiate ultraviolet light of about 325 nm to the second light emitting substance, and the light receiving part PU_2 can sense infrared light of 1012 nm emitted from the second light emitting substance.

[0417] Figure 26a and Figure 26b Both of the light emitting parts LU shown in FIG. 1 and FIG. 2 can be ultraviolet light emitting diodes.

[0418] In an embodiment, the semiconductor chip SC can be configured of an application specific integrated circuit for controlling the overall operation of the light sensor package PKG.

[0419] In an embodiment, the light receiving part PU_2 can be configured of at least one light receiving diode through which a current flows when receiving light (L') of a second wavelength different from light (L) of a first wavelength. For example, Figure 26a and Figure 26b The light receiving part PU_2 shown in FIG. 1 and FIG. 2 can be configured of an infrared light receiving diode capable of receiving light of an infrared wavelength, i.e., about 1000 nm to about 1020 nm.

[0420] Therefore, when the identifying substance contained in the cigarette 5 is a second luminescent substance, the light emitted by the luminescent part LU, which is composed of an ultraviolet light-emitting diode, can be sensed by the infrared light-receiving diode of the light-receiving part PU_2.

[0421] In one embodiment, the light-receiving part PU_2 may be disposed on the semiconductor chip SC. Furthermore, the height H1 from the first surface S1 (or upper surface) of the packaging substrate SUB to the upper surface of the semiconductor chip SC may be higher than the height H2 from the first surface S1 (or upper surface) of the packaging substrate SUB to the upper surface of the light-emitting part LU.

[0422] With Pass Figures 24a to 24d The situation is the same as described above. Figure 26a and Figure 26b In the optical sensor package PKG shown, the semiconductor chip SC has a partition function, which can prevent crosstalk and thus improve the sensing sensitivity of the optical sensor package PKG.

[0423] Figure 27a This is a top view of a light sensor package according to one embodiment. Figure 27b It is along Figure 27a A cross-sectional view of the optical sensor package taken along line IV-IV'.

[0424] Figure 27a and Figure 27b The optical sensor package PKG shown is Figures 24a to 24d The difference between the optical sensor package PKG shown is that the former also includes an additional light-receiving unit PU5, while the rest of the structure is essentially the same. The following will mainly describe the differences in the structure, and repeated descriptions of the same structure will be omitted.

[0425] Reference Figure 27a and Figure 27b In one embodiment, the optical sensor package PKG may further include an additional light-receiving part PU5, a third element PE3, and a second conductive member W2.

[0426] In one embodiment, the third element PE3 may be formed on the first surface S1 of the package substrate SUB. The third element PE3 may be connected to an additional light-collecting section PU5 composed of an infrared light-collecting diode.

[0427] For example, the third element PE3 can be composed of two terminals, including a cathode terminal and an anode terminal. The additional light-collecting part PU5 can be directly coupled to either of the two terminals. The second conductive member W2 can connect the additional light-collecting part PU5 to the other of the two terminals.

[0428] In one embodiment, the third element PE3 can be disposed on the first surface S1 opposite to the side where the first element PE1 is located, with the second element PE2 as a reference, and disposed adjacent to the second element PE2 on the first surface S1. Furthermore, the additional light-receiving part PU5 can be disposed on the first surface S1 opposite to the side where the light-emitting part LU is located, with the semiconductor chip SC as a reference, and disposed adjacent to the semiconductor chip SC on the first surface S1.

[0429] Since a semiconductor chip SC is disposed between the additional light-receiving part PU5 and the light-emitting part LU, the semiconductor chip SC can perform the function of a neighboring unit.

[0430] The surface of cigarette 5 may contain identification substance 10.

[0431] The identification substance 10 can be excited by light irradiated by the light-emitting part LU and can emit light in a wavelength range different from the wavelength range of the irradiated light. For example, the identification substance 10 can be excited by light in a first wavelength range irradiated by the light-emitting part LU and can emit light in a second wavelength range different from the first wavelength range.

[0432] For example, the identifying substance 10 can be a first luminescent substance that, when excited by light in a first wavelength range of about 350 nm to about 390 nm, emits light in a second wavelength range of about 400 nm to about 750 nm. Therefore, the luminescent part LU can irradiate the first luminescent substance with ultraviolet light of about 365 nm, and the light-receiving part PU can sense the visible light (i.e., red light) of 700 nm emitted by the first luminescent substance.

[0433] For example, the identifying substance 10 can be a second luminescent substance that, when excited by light in the first wavelength range of about 300 nm to about 340 nm, emits light in the second wavelength range of about 1000 nm to about 1020 nm. Therefore, the luminescent part LU can irradiate the second luminescent substance with ultraviolet light of about 325 nm, and the light-receiving part PU can sense the infrared light of 1012 nm emitted by the second luminescent substance.

[0434] Therefore, when the identifying substance contained in the cigarette 5 is the first luminescent substance, the light emitted by the luminescent part LU, which is composed of an ultraviolet light-emitting diode, can be sensed by the RGB sensing sensors (PU1, PU2, PU3) of the light-collecting part PU. When the identifying substance is the second luminescent substance, the light emitted by the luminescent part LU, which is composed of an ultraviolet light-emitting diode, can be sensed by the infrared light-collecting diode of the additional light-collecting part PU5.

[0435] Figure 28a This is a top view of a light sensor package according to one embodiment. Figure 28b It is along Figure 28a A cross-sectional view of the optical sensor package taken by the V-V' line.

[0436] Figure 28a and Figure 28b The optical sensor package PKG shown is Figure 27a and Figure 27b The difference between the optical sensor package PKG shown is that the former includes a light-emitting part LU composed of an ultraviolet light-emitting diode and a light-emitting part LU_1 composed of an infrared light-emitting diode, while the latter only includes a light-emitting part LU composed of an ultraviolet light-emitting diode; the rest of the components are essentially the same. The following will mainly describe the differences in the components; repeated descriptions of identical components will be omitted.

[0437] In the optical sensor package PKG, when the identification substance contained in the cigarette 5 is the first light-emitting substance, the light emitted by the light-emitting part LU, which is composed of an ultraviolet light-emitting diode, can be sensed by the RGB sensing sensors (PU1, PU2, PU3) of the light-receiving part PU. When the identification substance is the second light-emitting substance, the light emitted by the light-emitting part LU, which is composed of an ultraviolet light-emitting diode, can be sensed by the infrared light-receiving diode of the additional light-receiving part PU5.

[0438] Furthermore, when the identifying substance contained in the cigarette 5 is a third luminescent substance, the infrared light of the first wavelength emitted by the luminescent part LU_1, which is composed of an infrared light-emitting diode, can be excited into infrared light of the second wavelength and sensed by the infrared light-receiving diode of the attached light-receiving part PU5. On the other hand, the infrared light of the first wavelength emitted by the luminescent part LU_1, which is composed of an infrared light-emitting diode, can be directly sensed by the infrared light-receiving diode of the attached light-receiving part PU as the original infrared light of the first wavelength.

[0439] Since a semiconductor chip SC is disposed between the additional light-receiving part PU5 and the light-emitting parts LU and LU_1, the semiconductor chip SC can perform the function of the adjacent part.

[0440] Figure 29a This is a top view of a light sensor package according to one embodiment. Figure 29b It is along Figure 29a A cross-sectional view of the optical sensor package taken from line VI-VI'.

[0441] Figure 29a and Figure 29b The optical sensor package PKG shown is Figure 28a and Figure 28b The difference between the optical sensor package PKG shown is that the former does not include an RGB sensing sensor, but only includes an additional light-collecting part PU5 composed of an infrared light-collecting diode, while the latter includes a light-emitting part LU that includes both an RGB sensing sensor and the additional light-collecting part PU5 composed of an infrared light-collecting diode. The rest of the configuration is essentially the same. The following will mainly describe the different configurations, and repeated descriptions of the same configurations will be omitted.

[0442] In the light sensor package PKG illustrated in Figure 29a and Figure 29b When the identification substance contained in the cigarette 5 is the second luminescent substance, the light emitted from the light emitting portion LU composed of the ultraviolet light emitting diode can be sensed by the infrared light receiving diode of the additional light receiving portion PU5.

[0443] Further, when the identification substance contained in the cigarette 5 is the third luminescent substance, the infrared light of the first wavelength emitted from the light emitting portion LU_1 composed of the infrared light emitting diode can be excited to the infrared light of the second wavelength and sensed by the infrared light receiving diode of the additional light receiving portion PU5. On the other hand, the infrared light of the first wavelength emitted from the light emitting portion LU_1 composed of the infrared light emitting diode can be directly sensed by the infrared light receiving diode of the additional light receiving portion PU as the infrared light of the original first wavelength.

[0444] Since the semiconductor chip SC is disposed between the additional light receiving portion PU5 and the light emitting portion LU, LU_1, the semiconductor chip SC can function as a partition wall.

[0445] Figure 30a is a plan view of a light sensor package according to an embodiment, Figure 30b is a cross-sectional view of the light sensor package taken along the line VII-VII' of Figure 30a .

[0446] Figure 30a and Figure 30b The light sensor package PKG illustrated in Figure 24a to 24d differs from the light sensor package PKG illustrated in that the former does not include the semiconductor chip SC and includes only the light receiving portion PU composed of the RGB sensing sensor, while the latter includes the light receiving portion PU composed of the RGB sensing sensor disposed on the semiconductor chip SC, and the remaining configurations are substantially the same. Hereinafter, the configuration in which the difference exists will be mainly described, and the repeated description of the same configuration will be omitted.

[0447] Referring to Figure 30a and Figure 30b , in an embodiment, the light sensor package PKG can include the light receiving portion PU composed of the RGB sensing sensor, a fourth element PE4, and a third conductive member W3.

[0448] In an embodiment, the fourth element PE4 can be formed on the first surface S1 of the package substrate SUB. The fourth element PE4 can be connected to the light receiving portion PU composed of the RGB sensing sensor. The RGB sensing sensor can include a first photodiode PU1 for sensing red light, a second photodiode PU2 for sensing green light, and a third photodiode PU3 for sensing blue light.

[0449] For example, the fourth element PE4 can be composed of two terminals, including a cathode terminal and an anode terminal. The first photodiode PU1 can be directly connected to either of the two terminals. The third conductive member W3 can connect the first photodiode PU1 to the other of the two terminals. Similarly, the second photodiode PU2 can be directly connected to either of the two terminals. The third conductive member W3 can connect the second photodiode PU2 to the other of the two terminals. Likewise, the third photodiode PU3 can be directly connected to either of the two terminals. The third conductive member W3 can connect the third photodiode PU3 to the other of the two terminals.

[0450] Since the light-receiving unit (PU) can only sense visible light, the probability of crosstalk caused by the light-emitting unit (LU), which is composed of ultraviolet light-emitting elements, is theoretically low. Based on this, with... Figures 24a to 29b The illustrated embodiment differs from the one shown, corresponding to an embodiment in which the semiconductor chip SC, which has a separator function, is omitted. That is, Figure 30a and Figure 30b The optical sensor package PKG shown has advantages in miniaturization and reduced production costs. However, in reality, without a physical shielding structure, there is a possibility that the sensing sensitivity may be degraded due to the introduction of various noises.

[0451] On the contrary, as will be described later Figures 31a to 32b The optical sensor package PKG shown is obtained by... Figures 24a to 29b The illustrated embodiment also forms a partition structure, which can further reduce the possibility of crosstalk, thereby enhancing sensing sensitivity.

[0452] Below, in Figures 31a to 32b For ease of explanation, the following is shown: Figure 24a to 24d The illustrated embodiment shows an example of adding a spacer structure to the optical sensor package PKG. However, it is not limited to this; of course, other embodiments are also possible. Figures 25a to 30b A partition structure is added to the optical sensor package PKG shown.

[0453] Figure 31a This is a top view of a light sensor package according to one embodiment. Figure 31b It is along Figure 31a A cross-sectional view of the optical sensor package taken along line VIII-VIII'.

[0454] Figure 31a and Figure 31b The sensor package PKG shown is Figure 24a to 24dThe light sensor package shown in FIG. 1 is different from the light sensor package shown in FIG. 2 in that the former is provided with the partition wall PTW between the light emitting portion LU and the light receiving portion PU (or the semiconductor chip SC), whereas the latter does not include the partition wall PTW, and the rest of the configurations are substantially the same. Hereinafter, the configurations that are different will be mainly described, and the repeated description of the same configurations will be omitted.

[0455] Referring to Figure 24a to 24d , Figure 31a and Figure 31b , the partition wall PTW is located between the light emitting portion LU and the light receiving portion PU, and can prevent the light output from the light emitting portion LU from directly entering the light receiving portion PU.

[0456] The partition wall PTW is preferably formed of a material having a low light transmittance with respect to the light emitted from the light emitting portion LU, so as to reduce the incidence rate of the light output from the light emitting portion LU into the light receiving portion PU. For example, the partition wall PTW can be formed using black epoxy molding compound (EMC).

[0457] Conventionally, when a separately manufactured partition wall member is adhered to the package substrate SUB by an adhesive resin or the like, there is a problem that the light of the light emitting portion LU leaks and enters the light receiving portion PU through the portion where the adhesive resin is formed. In contrast, according to the manufacturing method of the light sensor package PKG of the present application, the partition wall PTW can be directly formed on the package substrate SUB by a transfer molding process. As described above, the light sensor package PKG of the present application can effectively prevent the light leakage phenomenon caused by the adhesive resin, by directly forming the partition wall PTW on the package substrate SUB without using the adhesive resin.

[0458] Further, the partition wall PTW is combined with the package substrate SUB, and thus can be formed of a material having a similar coefficient of thermal expansion to that of the package substrate SUB. For example, the coefficient of thermal expansion of the partition wall PTW can be 0.8 to 1.2 times the coefficient of thermal expansion of the package substrate SUB. In this case, the bonding force between the package substrate SUB and the partition wall PTW increases, and the warping phenomenon of the partition wall PTW decreases, so that the partition wall PTW can stably maintain the combined state with the package substrate SUB.

[0459] As shown in Figure 31a and Figure 31b , the partition wall PTW is located only between the light receiving portion PU and the light emitting portion LU, but in the optical sensor package PKG according to other embodiments, the partition wall PTW can be additionally formed along the periphery of the package substrate SUB, as shown in Figure 32a and Figure 32b , in addition to being located between the light receiving portion PU and the light emitting portion LU.

[0460] The optical sensor package PKG can include a molding member ENC disposed on the upper surface of the exposed portion of the package substrate SUB, the light emitting portion LU, the semiconductor chip SC, and the light receiving portion PU.

[0461] In one embodiment, the molding member ENC can be composed of a light-transmissive substance. For example, the molding member ENC can be a clear molding compound (CMC). The molding member ENC can guide the light emitted by the light emitting portion LU to be transmitted to the sensing object of the optical sensor package PKG, i.e., the identification portion ID of the cigarette 5.

[0462] The upper surface of the partition wall PTW is in the same plane as the upper surface of the molding member ENC, and the side surfaces of the partition wall PTW, except for the side surfaces opposite the light emitting portion LU, the light receiving portion PU, and the semiconductor chip SC, can be in the same plane as the side surfaces of the molding member ENC.

[0463] Figure 32a is a plan view of an optical sensor package according to one embodiment. Figure 32b is a cross-sectional view of the optical sensor package taken along the line VIIII-VIIII' of Figure 32a

[0464] Figure 32a and Figure 32b The optical sensor package PKG shown in Figure 31a and Figure 31b The optical sensor package PKG of

[0465] Referring to Figure 32a and Figure 32b The optical sensor package PKG can include a partition wall PTW including a first partition wall portion PTW1 disposed between the light emitting portion LU and the light receiving portion PU (or the semiconductor chip SC) and a second partition wall portion PTW2 extending in the first surface S1 direction (e.g., the +Z direction) along the edge of the package substrate SUB.

[0466] The partition wall PTW is preferably composed of a material having a relatively low light transmissivity with respect to the light emitted by the light emitting portion LU, to reduce the incidence of the light output by the light emitting portion LU into the light receiving portion PU. For example, the partition wall PTW can be formed using black epoxy molding compound (EMC).

[0467] ​The optical sensor package PKG can include a molding member ENC including a first molding part ENC1 disposed on an upper surface of an exposed portion of the package substrate SUB and the light emitting part LU, and a second molding part ENC2 disposed on an upper surface of another exposed portion of the package substrate SUB and the light receiving part PU and the semiconductor chip SC.

[0468] In an embodiment, the molding member ENC can be composed of a light-transmissive substance. For example, the molding member ENC can be a transparent molding compound (CMC). The molding member ENC can guide the light emitted by the light emitting part LU to be transferred to a sensing object of the optical sensor package PKG, i.e., the identification part ID of the cigarette 5.

[0469] An inner side surface of the partition wall PTW, which is in contact with the first molding part ENC1, can have a first inclined surface CL1 forming an obtuse angle with the first surface S1 (or the upper surface) of the package substrate SUB.

[0470] A reflective substance can be disposed on the inclined surface. The reflective substance can reflect the light diverging from the light emitting part LU to be uniformly diffused. For example, the reflective substance can include at least one material selected from the group consisting of glass, quartz, ceramic, poly methyl methacrylate (PMMA), polycarbonate, silicone resin, and plastic WEMC (white epoxy molding compound), PPA (polyphthalamide), PCT (poly 1,4-cyclohexane dimethanol terephthalate).

[0471] Further, an inner side surface of the partition wall PTW, which is in contact with the second molding part ENC2, can have a second inclined surface CL2 forming an obtuse angle with the first surface S1 (or the upper surface) of the package substrate SUB.

[0472] Figure 33a is a top view of an optical sensor package including a temperature sensor part according to an embodiment, Figure 33b is a cross-sectional view of the optical sensor package taken along the X-X' line of Figure 33a .

[0473] Referring to Figure 24a , Figure 33a and Figure 33b , an aerosol generating system according to an embodiment can include a cigarette 5 including an identification part ID that emits light of a second wavelength different from a first wavelength when excited by light of the first wavelength and an aerosol generating device 1.

[0474] The aerosol generating device 1 can include a body 100 including a cavity 100a into which the cigarette 5 is inserted, a light sensor package PKG disposed at a periphery of the cavity 100a and configured to sense the identification portion ID, and a control portion 110 configured to identify whether the cigarette 5 is counterfeit and a type of the cigarette 5 based on a sensed value sensed by the light sensor package PKG. At this time, Figure 24a The aerosol generating device 1 illustrated in FIG. 1 can correspond to the aerosol generating device 1 illustrated in Figure 7 and Figure 8 The aerosol generating device 1 illustrated in FIG. 1 can correspond to the aerosol generating device 1 illustrated in

[0475] The light sensor package PKG according to an embodiment can include a package substrate SUB, a light emitting portion LU, a semiconductor chip SC, a light receiving portion PU, a temperature sensor portion TS, and a molding member ENC.

[0476] In an embodiment, the first surface S1 can be a surface of the light sensor package PKG facing the identification portion ID of the cigarette 5. The substrate terminal TE can be electrically and / or physically connected to the aerosol generating device 1 of the present disclosure in which the light sensor package PKG is mounted.

[0477] The identification portion ID can include an identification substance. The identification substance can be excited when absorbing light of a predetermined wavelength range, and at this time, the "substance is excited" can mean that a state of the substance is changed from a ground state to an excited state. Subsequently, the light emitting substance can emit light of a predetermined wavelength range in a process in which the state of the identification substance is changed from the excited state to the ground state.

[0478] In an embodiment, the identification substance can be excited by light irradiated by the light emitting portion LU and can emit light of a wavelength range different from the wavelength range of the irradiated light. For example, the identification substance can be excited by light of a first wavelength range irradiated by the light emitting portion LU and can emit light of a second wavelength range different from the first wavelength range.

[0479] For example, the identification substance can be a first light emitting substance that emits light of a second wavelength range of about 400 nm to about 750 nm when excited by light of a first wavelength range of about 350 nm to about 390 nm. Accordingly, the light emitting portion LU can irradiate ultraviolet light of about 365 nm to the first light emitting substance, and the light receiving portion PU can sense visible light (i.e., red light) of 700 nm emitted by the first light emitting substance.

[0480] For another example, the identification substance can be a second light emitting substance that emits light of a second wavelength range of about 1000 nm to about 1020 nm when excited by light of a first wavelength range of about 300 nm to about 340 nm. Accordingly, the light emitting portion LU can irradiate ultraviolet light of about 325 nm to the second light emitting substance, and the light receiving portion PU_1 can sense infrared light of 1012 nm emitted by the second light emitting substance.

[0481] In one embodiment, the semiconductor chip SC can be constituted by an application specific integrated circuit for controlling the overall operation of the optical sensor package PKG.

[0482] In one embodiment, the light receiving section PU_1 can be constituted by at least one light receiving diode through which a current flows when receiving light (L') of a second wavelength different from the light (L) of the first wavelength. For example, Figure 33a and Figure 33b The light receiving section PU_1 illustrated in FIG. 8 can be an RGB sensing sensor. The RGB sensing sensor can internally include a first light diode PU1 for sensing red light, a second light diode PU2 for sensing green light, and a third light diode PU3 for sensing blue light. In addition, the light receiving section PU_1 can further include an infrared light receiving diode PU4 capable of receiving light of an infrared wavelength (i.e., about 1000 nm to about 1020 nm).

[0483] Therefore, when the identification substance contained in the cigarette 5 is the first luminescent substance, the light emitted from the light emitting section LU constituted by the ultraviolet light emitting diode can be sensed by the RGB sensing sensor (e.g., PU1, PU2, PU3) of the light receiving section PU_1, and when the identification substance is the second luminescent substance, the light emitted from the light emitting section LU constituted by the ultraviolet light emitting diode can be sensed by the infrared light receiving diode PU4 of the light receiving section PU_1.

[0484] In addition, when the identification substance contained in the cigarette 5 is the third luminescent substance, the first wavelength infrared light emitted from the light emitting section LU_1 constituted by the infrared light emitting diode can be excited to the second wavelength infrared light and sensed by the infrared light receiving diode PU4 of the light receiving section PU_1.

[0485] In one embodiment, the temperature sensor section TS can be disposed on the package substrate SUB. The solder balls SD can electrically connect the fifth element PE5 and the temperature sensor section TS. For example, the fifth element PE5 can be constituted by a plurality of terminals corresponding to the pad electrodes formed on the back surface of the temperature sensor section TS. The temperature sensor section TS can be combined to the fifth element PE5 by disposing the solder balls SD between the pad electrodes of the temperature sensor section TS and the plurality of electrodes of the fifth element PE5 and by a reflow process.

[0486] For example, the temperature sensor section TS can be constituted by an infrared temperature sensor TS_I. The temperature sensor section TS can include a case TS_C having an upper side partially opened, an infrared temperature sensor TS_I fitted to the inside of the case TS_C, a thermistor TS_T, and an infrared transmission window TS_F provided on the upper side of the opening of the case TS_C.

[0487] The infrared transmission window TS_F may, for example, include an infrared filter and a lens provided at an upper portion of the infrared temperature sensor TS_I. The infrared transmission window TS_F can transmit infrared light and provide the infrared light to the infrared temperature sensor TS_I.

[0488] Accordingly, the temperature sensor portion TS selects infrared light of a specific band from among infrared light incident through the infrared transmission window TS_F and provides the infrared light to the infrared temperature sensor TS_I, and converts the infrared light into an electrical signal through the thermistor TS_T, so that the ambient temperature of the cavity 100a can be measured.

[0489] In the aerosol generating device 1, the ambient temperature of the cavity 100a can increase when the heater 140 is in operation. Since the light emitting element (for example, a light emitting diode) of the light emitting portion LU changes in characteristics due to heat, the amount of light emitted by the light emitting portion LU can decrease when the temperature of the heater 140 increases, thereby causing the sensing function of the photosensor package PKG to decrease. Accordingly, to prevent the decrease in the amount of light emitted by the light emitting portion LU due to the increase in the temperature of the heater 140, the aerosol generating device 1 can correct the amount of light emitted by the light emitting portion LU.

[0490] For example, if the ambient temperature of the cavity 100a increases, the amount of light emitted by the light emitting portion LU can decrease. In this case, when the measured temperature of the temperature sensor portion TS changes by more than a preset reference temperature range, the semiconductor chip SC can correct the amount of light emitted by the light emitting portion LU according to the difference between the measured temperature and the upper limit value of the reference temperature range. By correcting the amount of light emitted by the light emitting portion LU, it is possible to prevent the sensing ability of the photosensor package PKG from decreasing. That is, the aerosol generating device 1 can compensate for the sensing value of the photosensor package PKG by increasing the amount of light emitted by the light emitting element of the light emitting portion LU, which decreases as the temperature of the heater 140 increases.

[0491] The semiconductor chip SC can control the duty cycle through pulse width modulation of the light emitting portion LU based on the offset value. The memory 130 can include a lookup table that corresponds the difference between the measured temperature and the upper limit value of the reference temperature range to the offset value for correcting the amount of light emitted by the light emitting portion LU. For example, as the ambient temperature of the cavity 100a increases, the difference between the measured temperature and the upper limit value of the reference temperature range increases, and thus the offset value can also increase.

[0492] The control portion 110 can determine whether the cigarette 5 is counterfeit and the type of the cigarette 5 based on the sensing value sensed by the photosensor package PKG.

[0493] In an embodiment, the molding member ENC can be disposed on the first surface S1 of the package substrate SUB. The molding member ENC can protect the first surface S1 of the package substrate SUB and other constituent elements (e.g., the light emitting part LU, the semiconductor chip SC, the temperature sensor part TS, and the light receiving part PU) mounted to the first surface S1. The molding member ENC can be made of a non-conductive material. The molding member ENC can reduce or prevent electrical disconnection or unnecessary short-circuit of the first surface S1 of the package substrate SUB and other constituent elements mounted to the first surface S1.

[0494] In an embodiment, the molding member ENC can be formed on the first surface S1 of the package substrate SUB to surround the light emitting part LU, the semiconductor chip SC, the temperature sensor part TS, and the light receiving part PU.

[0495] Figure 34 is a flowchart for explaining a light emitting amount correction operation method of an aerosol-generating system according to an embodiment.

[0496] Referring to Figure 24a , Figures 33a to 34 , the operation method of the aerosol-generating system according to an embodiment can include: a step S10 of inserting the cigarette 5 into the cavity 100a of the aerosol-generating device 1; a step S20 of measuring a peripheral temperature of the cavity 100a using the temperature sensor part TS included in the light sensor package PKG; and a step S30 of determining whether to correct a light emitting amount of the light emitting part LU included in the light sensor package PKG based on the measured peripheral temperature of the cavity 100a.

[0497] Specifically, in the step S10, the cigarette 5 can include an identification part ID that emits light of a second wavelength different from a first wavelength when excited by light of the first wavelength. The identification part ID can contain an identification substance that can be excited by ultraviolet light to thereby emit any one of red visible light, green visible light, blue visible light, and yellow visible light. For example, the identification substance can contain an organic substance that can contain one or more organic substances selected from the group consisting of quinazolinone-based compounds, thiophene-based compounds, sulfobenzoic acid-based compounds, and naphthylidine-based compounds.

[0498] In the step S20, the temperature sensor part TS can be constituted by an infrared temperature sensor TS_I. The temperature sensor part TS can include: a housing TS_C having an upper side partially open, an infrared temperature sensor TS_I mounted to the inside of the housing TS_C, a thermistor TS_T, and an infrared transmission window TS_F provided at the upper side of the opening of the housing TS_C.

[0499] The infrared transmission window TS_F may, for example, include an infrared filter and a lens disposed at an upper portion of the infrared temperature sensor TS_I. The infrared transmission window TS_F can transmit infrared light and provide the infrared light to the infrared temperature sensor TS_I.

[0500] Accordingly, the temperature sensor portion TS selects infrared light of a specific band from among infrared light incident through the infrared transmission window TS_F and provides the infrared light to the infrared temperature sensor TS_I, and converts the infrared light to an electrical signal through the thermistor TS_T, so that the ambient temperature of the cavity 100a can be measured.

[0501] In the aerosol generating device 1, the ambient temperature of the cavity 100a can increase when the heater 140 is in operation. Since the light emitting element (for example, a light emitting diode) of the light emitting portion LU changes in characteristics due to heat, the amount of light emitted by the light emitting portion LU can decrease when the temperature of the heater 140 increases, thereby causing the sensing function of the photosensor package PKG to decrease.

[0502] In step S30, when the ambient temperature of the cavity 100a measured by the temperature sensor portion TS is higher than the upper limit value of the preset reference temperature range, the semiconductor chip SC can determine to correct the amount of light emitted by the light emitting portion. At this time, the reference temperature range can be set in advance through experiments.

[0503] When the measured temperature of the temperature sensor portion TS varies above the preset reference temperature range, the semiconductor chip SC can correct the amount of light emitted by the light emitting portion LU according to the difference between the measured temperature and the upper limit value of the reference temperature range. By correcting the amount of light emitted by the light emitting portion LU, it is possible to prevent the sensing ability of the photosensor package PKG from decreasing. That is, the aerosol generating device 1 can compensate for the sensing value of the photosensor package PKG by increasing the amount of light emitted by the light emitting element of the light emitting portion LU, which decreases as the temperature of the heater 140 increases.

[0504] The semiconductor chip SC can control the duty cycle through pulse width modulation of the light emitting portion LU based on the offset value. The memory 130 can include a lookup table that corresponds the difference between the measured temperature and the upper limit value of the reference temperature range to the offset value for correcting the amount of light emitted by the light emitting portion LU. For example, as the ambient temperature of the cavity 100a increases, the difference between the measured temperature and the upper limit value of the reference temperature range increases, and thus the offset value can also increase.

[0505] On the other hand, since the aerosol generating device 1 belongs to small electronic products, the assembly space of various electronic components is limited, and the space for assembling the battery 120 can also be limited. Therefore, an effective solution is needed to effectively utilize the limited capacity of the battery 120.

[0506] ByFigures 24a to 33b The sensor part 150 (or, the optical sensor package PKG) includes a light emitting part LU, and to identify an identification part ID that emits light of a second wavelength different from a first wavelength when excited by light of the first wavelength, a light emitting diode for emitting ultraviolet light is commonly included. However, ultraviolet light belongs to light having a very short wavelength, and to make the light emitting part LU generate such light, higher power consumption is required compared to the case of generating visible light or infrared light. Therefore, from the viewpoint of reducing power consumption, regarding a scheme to minimize the operation of the light emitting part LU that emits ultraviolet light, the following is described in detail. Figures 35a to 36

[0507] Figure 35a is a top view of an optical sensor package including a light emitting part that emits visible light according to an embodiment, Figure 35b is a cross-sectional view of the optical sensor package taken along XI-XI' line of Figure 35a .

[0508] Referring to Figure 24a , Figure 35a and Figure 35b , the aerosol-generating system according to an embodiment can include a cigarette 5 and an aerosol-generating device 1, wherein the cigarette 5 includes an identification part ID that emits light of a second wavelength different from a first wavelength when excited by light of the first wavelength.

[0509] The aerosol-generating device 1 can include a body 100 including a cavity 100a into which the cigarette 5 is inserted, an optical sensor package PKG disposed at a periphery of the cavity 100a and used to sense the identification part ID, and a control part 110 that identifies whether the cigarette 5 is counterfeit and a kind of the cigarette 5 based on a sensed value sensed by the optical sensor package PKG. At this time, Figure 24a The aerosol-generating device 1 illustrated in Figure 7 and Figure 8 corresponds to the aerosol-generating device 1. Hereinafter, repeated descriptions are omitted.

[0510] The optical sensor package PKG according to an embodiment can include a package substrate SUB, a light emitting part LU, LU_2, a semiconductor chip SC, a light receiving part PU, and a molding member ENC. At this time, the optical sensor package PKG not only includes the light emitting part LU that emits ultraviolet light, but also can include a light emitting part LU_2 that emits visible light or ultraviolet light.

[0511] In an embodiment, the first surface S1 can be a surface of the optical sensor package PKG facing the identification part ID of the cigarette 5. The substrate terminal TE can be electrically and / or physically connected with the aerosol-generating device 1 of the present application in which the optical sensor package PKG is mounted.

[0512] Referring to Figure 20 ​The identification portion ID4 can be formed by overlapping the band pattern BP including the first identification substance and the grid pattern GP including the second identification substance in a thickness direction.

[0513] When the light emitting portion LU_2 is constituted by a white light emitting diode, the first identification substance can include a visible light reflecting substance. However, it is not limited thereto, and when the light emitting portion LU_2 is constituted by an infrared light emitting diode, the first identification substance can also include an infrared reflecting substance.

[0514] The second identification portion can include a second identification substance that emits light of a second wavelength different from the first wavelength when excited by light of the first wavelength.

[0515] The second identification substance can be excited when absorbing light of a predetermined wavelength range, and at this time, "the substance is excited" can mean that the state of the substance is changed from a ground state to an excited state. Subsequently, in a process in which the state of the second identification substance is changed from the excited state to the ground state, the light emitting substance can emit light of the predetermined wavelength range.

[0516] In an embodiment, the second identification substance can be excited by light irradiated from the light emitting portion LU and can emit light of a wavelength range different from the wavelength range of the irradiated light. For example, the second identification substance can be excited by light of a first wavelength range irradiated from the light emitting portion LU and can emit light of a second wavelength range different from the first wavelength range.

[0517] For example, the second identification substance can be a first light emitting substance that emits light of a second wavelength range of about 400 nm to about 750 nm when excited by light of a first wavelength range of about 350 nm to about 390 nm. Accordingly, the light emitting portion LU can irradiate ultraviolet light of about 365 nm to the first light emitting substance, and the light receiving portion PU can sense visible light (i.e., red light) of 700 nm emitted from the first light emitting substance.

[0518] For another example, the second identification substance can be a second light emitting substance that emits light of a second wavelength range of about 1000 nm to about 1020 nm when excited by light of a first wavelength range of about 300 nm to about 340 nm. Accordingly, the light emitting portion LU can irradiate ultraviolet light of about 325 nm to the second light emitting substance, and the light receiving portion PU_1 can sense infrared light of 1012 nm emitted from the second light emitting substance.

[0519] In an embodiment, the semiconductor chip SC can be constituted by an application specific integrated circuit for controlling the overall operation of the optical sensor package PKG.

[0520] In an embodiment, the light receiving portion PU_1 can be constituted by at least one light receiving diode through which a current flows when receiving light (L') of a second wavelength different from light (L) of a first wavelength. For example, Figure 35aand Figure 35b The light-receiving portion PU_1 shown can be an RGB sensing sensor. The RGB sensing sensor can internally include a first photodiode PU1 for sensing red light, a second photodiode PU2 for sensing green light, and a third photodiode PU3 for sensing blue light. In addition, the light-receiving portion PU_1 can also include an infrared light-receiving diode PU4 capable of receiving light of an infrared wavelength (i.e., about 1000 nm to about 1020 nm).

[0521] Therefore, when the second identification substance contained in the cigarette 5 is the first luminescent substance, the light emitted by the light-emitting portion LU composed of the ultraviolet light-emitting diode can be sensed by the RGB sensing sensor (e.g., PU1, PU2, PU3) of the light-receiving portion PU_1, and when the second identification substance is the second luminescent substance, the light emitted by the light-emitting portion LU composed of the ultraviolet light-emitting diode can be sensed by the infrared light-receiving diode PU4 of the light-receiving portion PU_1.

[0522] In addition, when the first identification substance contained in the cigarette 5 is a visible light reflecting substance, the white light emitted by the light-emitting portion LU_2 composed of the white light-emitting diode can be sensed by the RGB sensing sensor PU1, PU2, PU3 of the light-receiving portion PU_1.

[0523] On the other hand, the light-emitting portion LU_2 can also be composed of an infrared light-emitting diode. When the second identification substance contained in the cigarette 5 is an infrared reflecting substance, the infrared light can also be reflected and directly sensed by the infrared light-receiving diode PU4 of the light-receiving portion PU_1.

[0524] In an embodiment, the molding member ENC can be configured on the first surface S1 of the packaging substrate SUB. The molding member ENC can protect the first surface S1 of the packaging substrate SUB and other constituent elements (e.g., the light-emitting portions LU, LU_2, the semiconductor chip SC, and the light-receiving portion PU) assembled to the first surface S1. The molding member ENC can be made of a non-conductive material. The molding member ENC can reduce or prevent the first surface S1 of the packaging substrate SUB and other constituent elements assembled to the first surface S1 from being electrically disconnected or unnecessarily short-circuited.

[0525] In an embodiment, the molding member ENC can be formed on the first surface S1 of the packaging substrate SUB to surround the light-emitting portions LU, LU_2, the semiconductor chip SC, and the light-receiving portion PU.

[0526] Hereinafter, for convenience of explanation, a combination of the light emitting part LU_2 composed of a white light emitting diode (or an infrared light emitting diode) and the light receiving part PU_1 is defined as a first sensor part, and a combination of the light emitting part LU composed of a UV light emitting diode and the light receiving part PU_1 is defined as a second sensor part. The first sensor part according to an embodiment can repeat an ON state and an OFF state at a predetermined period, and can sense whether the cigarette 5 is inserted into the cavity 100a. For example, when the visible light (or infrared light) emitted from the light emitting part LU_1 is received by the light receiving part PU_1 after being reflected by the band pattern BP including the first recognition substance, the control part 110 can determine that the cigarette 5 is inserted into the cavity 100a, and switch the first sensor part to the OFF state and the second sensor part to the ON state.

[0527] Thereafter, the second sensor part can identify whether the cigarette 5 is counterfeit and the kind of the cigarette 5. For example, when the UV light emitted from the light emitting part LU is received by the light receiving part PU_1 after being excited and converted into visible light at the grid pattern GP including the second recognition substance, the control part 110 can compare the color information of the second recognition substance sensed by the second sensor part with the color information pre-stored in the memory 130, thereby determining the kind of the cigarette inserted into the cavity 100a.

[0528] At the end of the second recognition substance sensing event, the control part 110 can switch the second sensor part to the OFF state.

[0529] Subsequently, the control part 110 can operate in such a manner that the first sensor part repeats the ON state and the OFF state at a predetermined period. Through the sensing operation of the first sensor part, the moving state of the cigarette 5 can be sensed. For example, when the light amount of the visible light (or infrared light) reflected by the band pattern BP is sensed to be below a predetermined threshold value by the first sensor part, the control part 110 can determine that the cigarette 5 moves within the cavity 100a. At this time, the state in which the cigarette 5 moves means a state in which the cigarette 5 is difficult to be sufficiently heated by the heater 140, resulting in a state in which a sufficient smoking sensation cannot be provided to a user of the aerosol generating device 1.

[0530] Upon determining that the cigarette 5 moves within the cavity 100a, the control part 110 can perform an intelligent shutdown operation to stop the operation of the heater 140.

[0531] Figure 36 is a flowchart for explaining a power consumption reduction operation of the aerosol generating system according to an embodiment.

[0532] Referring to Figure 24a , Figure 35a and Figure 36, the method of operation of the aerosol generating system according to an embodiment can include: step S11, inserting the cigarette 5 into the cavity 100a of the aerosol generating device 1; step S21, determining whether the cigarette 5 is inserted into the cavity 100a based on a sensing value of a first identification portion (for example: Figure 20 of the band pattern BP) sensed by a first sensor portion included in the light sensor package PKG disposed on the periphery of the cavity 100a; and step S31, when it is determined that the cigarette 5 is inserted into the cavity 100a, determining the type of the cigarette 5 based on a sensing value of a second identification portion (for example: Figure 20 of the grid pattern GP) sensed by a second sensor portion included in the light sensor package PKG.

[0533] Specifically, in step S11, with reference to Figure 20 , the identification portion ID4 can be formed by overlapping the band pattern BP including the first identification substance and the grid pattern GP including the second identification substance in the thickness direction. When the light emitting portion LU_2 is composed of a white light emitting diode, the first identification substance can include a visible light reflecting substance. However, it is not limited thereto, and when the light emitting portion LU_2 is composed of an infrared light emitting diode, the first identification substance can also include an infrared reflecting substance.

[0534] The second identification portion can include a second identification substance that emits light of a second wavelength different from the first wavelength when excited by light of the first wavelength. The second identification substance can be excited by ultraviolet light and emit any one of red visible light, green visible light, blue visible light, and yellow visible light. For example, the second identification substance can include an organic substance, and the organic substance can include one or more organic substances selected from the group consisting of quinazolinone-based compounds, thiophene-based compounds, sulfobenzoic acid-based compounds, and naphthylidine-based compounds.

[0535] In step S21, the first sensor portion can repeat an ON state and an OFF state at a predetermined period, and can sense whether the cigarette 5 is inserted into the cavity 100a. For example, when the visible light (or infrared light) emitted from the light emitting portion LU_1 is received by the light receiving portion PU_1 after being reflected by the band pattern BP including the first identification substance, the control portion 110 can determine that the cigarette 5 is inserted into the cavity 100a, and switch the first sensor portion to the OFF state and the second sensor portion to the ON state.

[0536] In step S31, the second sensor portion can identify whether the cigarette 5 is counterfeit or not and the type of the cigarette 5. For example, when the ultraviolet light emitted from the light emitting portion LU is excited by the grid pattern GP containing the second identification substance and converted into visible light, which is then received by the light receiving portion PU_1, the control portion 110 can compare the color information of the second identification substance sensed by the second sensor portion with the color information stored in advance in the memory 130, thereby determining the type of the cigarette inserted into the cavity 100a.

[0537] At the end of the second identification substance sensing event, the control portion 110 can switch the second sensor portion to the off state.

[0538] The method of operation of the aerosol generating system according to an embodiment can further include a step of, after starting the supply of power to the heater 140, stopping the operation of the heater 140 if the first sensor portion fails to sense the first identification portion.

[0539] The control portion 110 can operate in such a manner that the first sensor portion repeats the on state and the off state at a predetermined period. Through the sensing operation of the first sensor portion, the movement state of the cigarette 5 can be sensed. For example, when the amount of light of the visible light (or infrared light) reflected by the band pattern BP is sensed by the first sensor portion to be below a predetermined threshold value, the control portion 110 can determine that the cigarette 5 has moved within the cavity 100a. At this time, the state in which the cigarette 5 moves means a state in which the cigarette 5 is difficult to be sufficiently heated by the heater 140, resulting in a state in which a sufficient smoking sensation cannot be provided to the user of the aerosol generating device 1.

[0540] When it is determined that the cigarette 5 moves within the cavity 100a, the control portion 110 can perform an intelligent shutdown operation to stop the operation of the heater 140.

[0541] Figure 37 is a block diagram of an aerosol generating device according to another embodiment.

[0542] The aerosol generating device 1000 can include a power supply 1100, a control portion 1200, a sensor 1300, an output portion 1400, an input portion 1500, a communication portion 1600, a memory 1700, and at least one heater (e.g., a heater 1800, 2400). However, the internal structure of the aerosol generating device 1000 is not limited to that shown in Figure 37 that is, depending on the design of the aerosol generating device 1000, it can be understood by those skilled in the art that Figure 37 part of the configuration shown in

[0543] The sensor 1300 can sense a state of the aerosol generating device 1000 or a state of the surroundings of the aerosol generating device 1000, and deliver the sensed information to the control portion 1200. The control portion 1200 can control the aerosol generating device 1000 based on the sensed information to perform various functions, such as action control of the cartomizer heater 2400 and / or the heater 1800, restriction of smoking, judgment of insertion or non-insertion of the aerosol generating article and / or the cartomizer, notification display, etc.

[0544] The sensor 1300 can include at least one of a temperature sensor 1310, a puffing sensor 1320, an insertion sensing sensor 1330, a reuse sensing sensor 1340, a cartomizer sensing sensor 1350, a cap sensing sensor 1360, and a movement sensing sensor 1370.

[0545] The temperature sensor 1310 can sense a temperature at which the cartomizer heater 2400 and / or the heater 1800 is heated. The aerosol generating device 1000 can include a separate temperature sensor for sensing the temperature of the cartomizer heater 2400 and / or the heater 1800, or the cartomizer heater 2400 and / or the heater 1800 itself can function as the temperature sensor.

[0546] The temperature sensor 1310 can output a signal corresponding to the temperature of the cartomizer heater 2400 and / or the heater 1800. For example, the temperature sensor 1310 can include a resistance element whose resistance value changes in response to a change in the temperature of the cartomizer heater 2400 and / or the heater 1800. This can be implemented by a thermistor or the like having a property that the resistance changes with temperature. At this time, the temperature sensor 1310 can output a signal corresponding to the resistance value of the resistance element as a signal corresponding to the temperature of the cartomizer heater 2400 and / or the heater 1800. For example, the temperature sensor 1310 can be constituted by a sensor that senses the resistance value of the cartomizer heater 2400 and / or the heater 1800. At this time, the temperature sensor 1310 can output a signal corresponding to the resistance value of the cartomizer heater 2400 and / or the heater 1800 as a signal corresponding to the temperature of the cartomizer heater 2400 and / or the heater 1800.

[0547] The temperature sensor 1310 can be disposed around the power supply 1100 to monitor the temperature of the power supply 1100. The temperature sensor 1310 can be disposed adjacent to the power supply 1100. For example, the temperature sensor 1310 can be attached to a surface of a battery that is the power supply 1100. For example, the temperature sensor 1310 can be mounted on a surface of a printed circuit board.

[0548] The temperature sensor 1310 is disposed inside the aerosol generating device body and can sense an internal temperature of the aerosol generating device body.

[0549] The puffing sensor 1320 can sense a user's puffing based on various physical changes of the airflow passage. The puffing sensor 1320 can output a signal corresponding to the puffing. For example, the puffing sensor 1320 can be a pressure sensor. The puffing sensor 1320 can output a signal corresponding to an internal pressure of the aerosol generating device. Herein, the internal pressure of the aerosol generating device 1000 can correspond to a pressure of the airflow passage in which the gas flows. The puffing sensor 1320 can be disposed corresponding to the airflow passage in which the gas flows in the aerosol generating device 1000.

[0550] The insertion sensing sensor 1330 can sense insertion and / or removal of the aerosol generating article. The insertion sensing sensor 1330 can sense a change in a signal due to the aerosol generating article being inserted and / or removed. The insertion sensing sensor 1330 can be disposed at a periphery of the insertion space. The insertion sensing sensor 1330 can sense insertion and / or removal of the aerosol generating article according to a change in a dielectric constant inside the insertion space. For example, the insertion sensing sensor 1330 can be an inductive sensor and / or a capacitive sensor.

[0551] The inductive sensor can include at least one coil. The coil of the inductive sensor can be disposed adjacent to the insertion space. For example, when a magnetic field of a periphery of the coil through which a current flows changes, according to Faraday's law of electromagnetic induction, a characteristic of the current flowing through the coil can change. Herein, the characteristic of the current flowing through the coil can include a frequency of an alternating current, a current value, a voltage value, an inductance value, an impedance value, etc.

[0552] The inductive sensor can output a signal corresponding to the characteristic of the current flowing through the coil. For example, the inductive sensor can output a signal corresponding to an inductance value of the coil.

[0553] The capacitive sensor can include an electric conductor. The electric conductor of the capacitive sensor can be disposed adjacent to the insertion space. The capacitive sensor can output a signal corresponding to an electromagnetic characteristic of the periphery, for example, a capacitance of the periphery of the electric conductor. For example, when the aerosol generating article including a wrapping paper of a metallic material is inserted into the insertion space, the electromagnetic characteristic of the periphery of the electric conductor can change due to the wrapping paper of the aerosol generating article.

[0554] The reuse sensing sensor 1340 can sense whether the aerosol generating article is reused. The reuse sensing sensor 1340 can be a color sensor. The color sensor can sense the color of the aerosol generating article. The color sensor can sense the color of a portion of the wrapping paper wrapping the outside of the aerosol generating article. The color sensor, based on light reflected from an object, can sense a value of an optical characteristic corresponding to the color of the object. For example, the optical characteristic can be the wavelength of light. The color sensor can be implemented as a single structure together with the proximity sensor, or as a separate structure different from the proximity sensor.

[0555] The color of at least a portion of the wrapping paper constituting the aerosol generating article can change due to aerosol. The reuse sensing sensor 1340 can be disposed at a position corresponding to a position at which at least a portion of the wrapping paper whose color changes due to aerosol is disposed when the aerosol generating article is inserted into the insertion space. For example, before the aerosol generating article is used by a user, the color of at least a portion of the wrapping paper can be a first color. At this time, in a process in which aerosol generated by the aerosol generating device 1000 passes through the aerosol generating article, as at least a portion of the wrapping paper is wetted by the aerosol, the color of at least a portion of the wrapping paper can change to a second color. In addition, the color of at least a portion of the wrapping paper can be maintained at the second color after changing from the first color to the second color.

[0556] The cartridge sensing sensor 1350 can sense the installation and / or removal of the cartridge. The cartridge sensing sensor 1350 can be implemented by an inductance-based sensor, a capacitive sensor, a resistance sensor, a hall sensor (hall IC) utilizing a hall effect, or the like.

[0557] The cap sensing sensor 1360 can sense the installation and / or removal of the cap. When the cap is separated from the aerosol generating device body, a portion of the cartridge and the aerosol generating device body covered by the cap can be exposed to the outside. The cap sensing sensor 1360 can be implemented by a contact sensor, a hall sensor, an optical sensor, or the like.

[0558] The movement sensing sensor 1370 can sense the movement of the aerosol generating device. The movement sensing sensor 1370 can be implemented by at least one of an acceleration sensor and a gyro sensor.

[0559] The sensor 1300 can further include at least one of a humidity sensor, an air pressure sensor, a magnetic sensor, a location sensor (GPS), and a proximity sensor, in addition to the above-described sensors (1310 to 1370). The functions of the respective sensors can be intuitively inferred by those skilled in the art from their names, and thus specific descriptions will be omitted.

[0560] The output 1400 can output the state information of the aerosol generating device 1000 and provide it to the user. The output 1400 can include at least one of a display 1410, a haptic 1420, and an audio output 1430, but is not limited thereto. When the display 1410 forms a layered structure with a touch panel and constitutes a touch screen, the display 1410 can be used as an input device in addition to being an output device.

[0561] The display 1410 can provide information of the aerosol generating device 1000 to the user in a visual manner. For example, the information of the aerosol generating device 1000 can be various information such as a charging / discharging state of the power supply 1100 of the aerosol generating device 1000, a preheating state of the heater 1800, an insertion / removal state of the aerosol generating article and / or the cartridge, a mounting / removal state of the cover, or a state in which the use of the aerosol generating device 1000 is limited (for example: an abnormal article is sensed), and the display 1410 can output the information to the outside. For example, the display 1410 can be in the form of an LED light emitting element. For example, the display 1410 can be a liquid crystal display panel (LCD), an organic light emitting display panel (OLED), or the like.

[0562] The haptic 1420 converts an electrical signal into a mechanical stimulus or an electrical stimulus, and thus can provide information of the aerosol generating device 1000 to the user in a tactile manner. For example, when initial power is supplied to the cartridge heater 2400 and / or the heater 1800 for a set time, the haptic 1420 can emit a vibration corresponding to the completion of the initial preheating. The haptic 1420 can include a vibration motor, a piezoelectric element, or an electrical stimulation device.

[0563] The audio output 1430 can provide information of the aerosol generating device 1000 to the user in an auditory manner. For example, the audio output 1430 can convert an electrical signal into an audio signal and output it to the outside.

[0564] The power supply 1100 can supply power required for the operation of the aerosol generating device 1000. The power supply 1100 can supply power to enable the cartridge heater 2400 and / or the heater 1800 to be heated. In addition, the power supply 1100 can supply power required for the operation of other structures (the sensor 1300, the output 1400, the input 1500, the communication 1600, and the storage 1700) provided in the aerosol generating device 1000. The power supply 1100 can be a rechargeable battery or a primary battery. For example, the power supply 1100 can be a lithium polymer (LiPoly) battery, but is not limited thereto.

[0565] Figure 37Although not illustrated, the aerosol generating device 1000 can further include a power protection circuit. The power protection circuit is electrically connected with the power supply 1100 and can include a switching element.

[0566] The power protection circuit can block a circuit of the power supply 1100 according to a predetermined condition. For example, when a voltage level of the power supply 1100 is above a first voltage corresponding to overcharge, the power protection circuit can block the circuit of the power supply 1100. For example, when the voltage level of the power supply 1100 does not reach a second voltage corresponding to overdischarge, the power protection circuit can block the circuit of the power supply 1100.

[0567] The heater 1800 receives power from the power supply 1100 and can heat a medium or an aerosol generating material within an aerosol generating article. Figure 37 Although not illustrated, the aerosol generating device 1000 can further include a power conversion circuit (e.g., a DC / DC converter) that converts power of the power supply 1100 and supplies the power to the cartridge heater 2400 and / or the heater 1800. In addition, when the aerosol generating device 1000 generates an aerosol in an inductive heating method, the aerosol generating device 1000 can further include a DC / AC converter that converts a direct current power of the power supply 1100 into an alternating current power.

[0568] The control portion 1200, the sensor 1300, the output portion 1400, the input portion 1500, the communication portion 1600, and the storage 1700 can receive power from the power supply 1100 to perform functions. Figure 37 Although not illustrated, a power conversion circuit, such as a low dropout (LDO) circuit or a voltage regulator circuit, that converts power of the power supply 1100 to supply the power to each constituent element can be further included. In addition, Figure 37 Although not illustrated, a noise filter can be further provided between the power supply 1100 and the heater 1800. The noise filter can be a low pass filter. The low pass filter can include at least one inductor and a capacitor. A blocking frequency of the low pass filter can correspond to a frequency of a high-frequency switching current applied from the power supply 1100 to the heater 1800. Through the low pass filter, a high-frequency noise component can be prevented from being applied to the sensor 1300, such as the insertion sensing sensor 1330.

[0569] In an embodiment, the cartridge heater 2400 and / or the heater 1800 can be formed of any suitable electrically resistive material. For example, the suitable electrically resistive material can be a metal or a metal alloy including titanium, zirconium, tantalum, platinum, nickel, cobalt, chromium, hafnium, niobium, molybdenum, tungsten, tin, gallium, manganese, iron, copper, stainless steel, nichrome, etc., but is not limited thereto. In addition, the heater 1800 can be implemented by a metal heating plate configured with a metal heating wire, an electrically conductive track, a ceramic heating element, etc., but is not limited thereto.

[0570] In other embodiments, the heater 1800 can be a heater of an induction heating type. For example, the heater 1800 can include a susceptor that is heated by a magnetic field applied by a coil and heats an aerosol generating material.

[0571] The input 1500 can receive information input by a user or output information to the user. For example, the input 1500 can be a touch panel. The touch panel can include at least one touch sensor that senses a touch. For example, the touch sensor can include a capacitive touch sensor, a resistive touch sensor, an ultrasonic touch sensor (surface acoustic wave touch sensor), an infrared touch sensor, etc., but is not limited thereto.

[0572] The display 1410 and the touch panel can be implemented by one panel. For example, the touch panel can be inserted into the display 1410 (On-Cell type or In-Cell type). For example, the touch panel can be an Add-On type that is an additional member on the panel of the display 1410.

[0573] In addition, the input 1500 can include a button, a keypad, a dome switch, a jog wheel, a jog switch, etc., but is not limited thereto.

[0574] The memory 1700, which is hardware that stores various data processed within the aerosol generating device 1000, can store data processed by the control portion 1200 and data to be processed. The memory 1700 can include at least one type of storage medium among a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (e.g., an SD or XD memory, etc.), a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, and an optical disk. The memory 1700 can store data, such as an operation time of the aerosol generating device 1000, a maximum number of puffs, a current number of puffs, at least one temperature profile, and a user's smoking pattern.

[0575] The communication portion 1600 can include at least one component for communication with other electronic devices. For example, the communication portion 1600 can include at least one of a short-range communication portion and a wireless communication portion.

[0576] The short-range communication portion (short-range wireless communication unit) can include a Bluetooth communication portion, a Bluetooth Low Energy (BLE) communication portion, a Near Field Communication unit, a WLAN (Wi-Fi) communication portion, a Zigbee communication portion, an infrared Data Association (IrDA) communication portion, a Wi-Fi Direct (WFD) communication portion, an ultra-wideband (UWB) communication portion, an Ant+ communication portion, etc., but is not limited thereto.

[0577] The wireless communication portion can include a cellular network communication portion, an Internet communication portion, a computer network (e.g., a LAN or a WAN) communication portion, etc., but is not limited thereto.

[0578] Figure 37Although not illustrated, the aerosol generating device 1000 can further include a connection interface such as a universal serial bus (USB) interface, and be connected to other external devices through the connection interface such as the USB interface to transmit and receive information or charge the power supply 1100.

[0579] The control portion 1200 can control the overall operation of the aerosol generating device 1000. In an embodiment, the control portion 1200 can include at least one processor. The processor can be implemented by an array of a plurality of logic gates, or can be implemented by a combination of a general-purpose microprocessor and a memory in which a program executable in the microprocessor is stored. In addition, it can also be implemented by other forms of hardware as long as it is understood by those of ordinary skill in the art to which the present embodiment pertains.

[0580] The control portion 1200 can control the temperature of the heater 1800 by controlling the power supply of the heater 1800 by the power supply 1100. The control portion 1200 can control the temperature of the cartridge heater 2400 and / or the heater 1800 based on the temperature of the cartridge heater 2400 and / or the heater 1800 sensed by the temperature sensor 1310. The control portion 1200 can adjust the power supplied to the cartridge heater 2400 and / or the heater 1800 based on the temperature of the cartridge heater 2400 and / or the heater 1800. For example, the control portion 1200 can determine a target temperature for the cartridge heater 2400 and / or the heater 1800 based on a temperature profile stored in the memory 1700.

[0581] The aerosol generating device 1000 can include a power supply circuit (not illustrated) electrically connected to the power supply 1100 between the power supply 1100 and the cartridge heater 2400 and / or the heater 1800. The power supply circuit can be electrically connected to the cartridge heater 2400, the heater 1800, or the induction coil. The power supply circuit can include at least one switching element. The switching element can be implemented by a bipolar junction transistor (BJT), a field effective transistor (FET), or the like. The control portion 1200 can control the power supply circuit.

[0582] The control portion 1200 can control the power supply by controlling the turn-on and turn-off of the switching element of the power supply circuit. The power supply circuit can be an inverter that converts the direct current power output from the power supply 1100 into alternating current power. For example, the inverter can be constituted by a full-bridge circuit or a half-bridge circuit including a plurality of switching elements.

[0583] The control portion 1200 can cause the switching element to be turned on to cause the power supply 1100 to supply power to the cartridge heater 2400 and / or the heater 1800. The control portion 1200 can cause the switching element to be turned off to block the supply of power to the cartridge heater 2400 and / or the heater 1800. The control portion 1200 can adjust the current supplied by the power supply 1100 by adjusting the frequency and / or the duty ratio of the current pulse input to the switching element.

[0584] The control portion 1200 can control the voltage output by the power supply 1100 by controlling the turning on and off of the switching element of the power supply circuit. The power conversion circuit can convert the voltage output by the power supply 1100. For example, the power conversion circuit can include a Buck-converter that steps down the voltage output by the power supply 1100. For example, the power conversion circuit can be implemented by a Buck-boost converter, a Zener diode, or the like.

[0585] The control portion 1200 can adjust the level of the voltage output in the power conversion circuit by controlling the turning on or off action of the switching element included in the power conversion circuit. When the on state of the switching element is maintained, the level of the voltage output by the power conversion circuit can correspond to the level of the voltage output by the power supply 1100. The duty ratio of the turning on or off action of the switching element can correspond to the ratio of the voltage output by the power conversion circuit to the voltage output by the power supply 1100. As the duty ratio of the turning on or off action of the switching element decreases, the level of the voltage output by the power conversion circuit can also decrease. The heater 1800 can be heated based on the voltage output by the power conversion circuit.

[0586] The control portion 1200 can supply power to the heater 1800 using at least one of a pulse width modulation (PWM) method and a Proportional-Integral-Differential (PID) method.

[0587] For example, the control portion 1200 can control the supply of the current pulse having a predetermined frequency and a duty ratio to the heater 1800 using the PWM method. The control portion 1200 can control the power supplied to the heater 1800 by adjusting the frequency and the duty ratio of the current pulse.

[0588] For example, the control portion 1200 can determine a target temperature that becomes a control target based on a temperature profile. The control portion 1200 can control the power supplied to the heater 1800 using the PID method (a feedback control method using a difference between the temperature of the heater 1800 and the target temperature, a value obtained by integrating the difference over time, and a value obtained by differentiating the difference over time).

[0589] The control portion 1200 can prevent the cartomizer heater 2400 and / or the heater 1800 from being overheated. For example, when the temperature of the cartomizer heater 2400 and / or the heater 1800 exceeds a preset limit temperature, the control portion 1200 can control the operation of the power conversion circuit in a manner of interrupting the supply of power to the cartomizer heater 2400 and / or the heater 1800. For example, when the temperature of the cartomizer heater 2400 and / or the heater 1800 exceeds a preset limit temperature, the control portion 1200 can reduce the amount of power supplied to the cartomizer heater 2400 and / or the heater 1800 by a predetermined ratio. For example, when the temperature of the cartomizer heater 2400 exceeds the limit temperature, the control portion 1200 can determine that the aerosol generating material accommodated in the cartomizer is depleted, and block the supply of power to the cartomizer heater 2400.

[0590] The control portion 1200 can control the charging and discharging of the power supply 1100. The control portion 1200 can confirm the temperature of the power supply 1100 based on the output signal of the temperature sensor 1310.

[0591] When the electric wire is connected to the battery terminal of the aerosol generating device 1000, the control portion 1200 can confirm whether the temperature of the power supply 1100 is above a first limit temperature that is a reference for blocking the charging of the power supply 1100. When the temperature of the power supply 1100 does not reach the first limit temperature, the control portion 1200 can control to charge the power supply 1100 based on a preset charging current. When the temperature of the power supply 1100 is above the first limit temperature, the control portion 1200 can block the charging of the power supply 1100.

[0592] When the power supply of the aerosol generating device 1000 is in a turned-on state, the control portion 1200 can confirm whether the temperature of the power supply 1100 is above a second limit temperature that is a reference for blocking the discharging of the power supply 1100.
