Description

[Technical Field]

[0001] The present invention relates to an aerosol generating apparatus and a method for manufacturing an external cover for an aerosol generating apparatus, and more particularly to an aerosol generating apparatus including an external cover that can reduce the positional deviation between the light source and the external cover, and make the holes for transmitting light invisible from the outside, thereby ensuring uniformity of the light emitted to the outside and improving the overall aesthetics of the aerosol generating apparatus, and a method for manufacturing an external cover for an aerosol generating apparatus. [Background technology]

[0002] Recently, there has been a growing demand for alternative methods to overcome the shortcomings of conventional cigarettes. For example, there is a growing demand for systems that generate aerosols by heating cigarettes or aerosol-generating materials using aerosol generators, rather than by burning cigarettes to produce aerosols.

[0003] As aerosol generators become increasingly versatile, a variety of notification functions are being added. In particular, multiple light-emitting elements are being used to precisely display information such as the number of puffs and battery level. However, the increased number of light-emitting elements in an aerosol generator leads to problems such as an increase in the number of components required for displaying them, and a decrease in aesthetics due to tolerances between parts. [Overview of the Initiative] [Problems that the invention aims to solve]

[0004] The various embodiments of the present invention aim to improve the overall aesthetics of an aerosol generating device while ensuring uniformity of the light emitted to the outside, by making the holes for transmitting light emitted from the light-emitting member and displaying it on the outer cover invisible from the outside.

[0007] Furthermore, a method for manufacturing an external cover for an aerosol generating apparatus according to one embodiment includes the steps of: providing a base layer; sequentially laminating a light-transmitting layer, a shielding layer, and a coating layer on the front surface of the base layer; and arranging a circuit layer on the back surface of the base layer, wherein the base layer, the light-transmitting layer, the shielding layer, and the coating layer contain a light-transmitting material, and the light emitted from the light-emitting member is transmitted through the base layer, the light-transmitting layer, the shielding layer, and the coating layer in that order.

[0008] The means of solving the problem are not limited to those described above, but include any matters that can be inferred by analogy to those skilled in the art throughout this specification. [Effects of the Invention]

[0009] The aerosol generating apparatus according to this embodiment can utilize multiple light sources efficiently and provide a structure that does not impair the overall aesthetics of the apparatus.

Modes for Carrying Out the Invention

[0012] In the embodiments, the terminology used has been selected to be as widely used and general as possible, taking into account the functions of the present invention. However, this may change depending on the intentions of those skilled in the art, precedents, the emergence of new technologies, etc. In certain cases, the applicant may have arbitrarily selected some terms, in which case their meaning will be described in detail in the description of the invention. Therefore, the terminology used in the present invention must not be merely names of terms, but must be defined based on the meaning of the term and the overall content of the present invention.

[0013] Throughout the specification, when a part "includes" a component, this means, unless otherwise stated, that it may include other components, not exclude them. Furthermore, terms such as "~part" and "~module" used in the specification refer to a unit that processes at least one function or operation, which may be embodied in hardware or software, or in a combination of hardware and software.

[0014] As used herein, when an expression such as "at least one of the listed components" precedes a list of components, it modifies the group of components as a whole, rather than each of the listed components. For example, the expression "at least one of a, b, and c" must be interpreted as including a, b, c, or a and b, a and c, b and c, or a, b, and c.

[0015] Furthermore, while ordinal terms such as "first" or "second" used herein may be used to describe various components, the components should not be limited by these terms. The terms are used solely for the purpose of distinguishing one component from others.

[0016] Throughout the specification, the “aerosol generating device” is a device that generates an aerosol using an aerosol generating substance in order to generate an aerosol that can be directly inhaled into the user’s lungs through the user’s mouth.

[0017] Throughout this specification, “cigarette” means an article used for smoking. For example, a cigarette may be a combustion cigarette used by being ignited and burned, or a heated cigarette used by being heated by an aerosol generator.

[0018] The embodiments of the present invention will be described in detail below with reference to the attached drawings, so that those skilled in the art can easily implement them. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein.

[0019] Embodiments of the present invention will be described in detail below with reference to the drawings.

[0020] Figures 1 through 3 show examples of a cigarette being inserted into an aerosol generator.

[0021] Referring to Figure 1, the aerosol generator 1 comprises a battery 11, a control unit 12, and a heater 13. Referring to Figures 2 and 3, the aerosol generator 1 further comprises a vaporizer 14. A cigarette 2 is inserted into the internal space of the aerosol generator 1.

[0022] The aerosol generator 1 shown in Figures 1 to 3 represents the components according to this embodiment. Therefore, those skilled in the art will understand that, in addition to the components shown in Figures 1 to 3, other general-purpose components may be further provided in the aerosol generator 1.

[0023] Furthermore, although Figures 2 and 3 show that the aerosol generator 1 is equipped with a heater 13, the heater 13 may be omitted if necessary.

[0024] Figure 1 shows that the battery 11, control unit 12, and heater 13 are arranged in a line. Figure 2 shows that the battery 11, control unit 12, vaporizer 14, and heater 13 are arranged in a line. Figure 3 shows that the vaporizer 14 and heater 13 are arranged in parallel. However, the internal structure of the aerosol generator 1 is not limited to what is shown in Figures 1 to 3. In other words, the arrangement of the battery 11, control unit 12, heater 13, and vaporizer 14 may be changed depending on the design of the aerosol generator 1.

[0025] When a cigarette 2 is inserted into the aerosol generator 1, the aerosol generator 1 activates the heater 13 and / or vaporizer 14 to generate an aerosol. The aerosol generated by the heater 13 and / or vaporizer 14 passes through the cigarette 2 and is transmitted to the user.

[0026] If necessary, the aerosol generator 1 will heat the heater 13 even if the cigarette 2 is not inserted into the aerosol generator 1.

[0027] The battery 11 supplies the power used when the aerosol generator 1 operates. For example, the battery 11 supplies power to heat the heater 13 or vaporizer 14, and supplies the power necessary for the control unit 12 to operate. The battery 11 also supplies the power necessary for the operation of the display, sensors, motors, etc., provided in the aerosol generator 1.

[0028] The control unit 12 controls the overall operation of the aerosol generator 1. Specifically, the control unit 12 controls the operation of not only the battery 11, heater 13, and vaporizer 14, but also other components of the aerosol generator 1. The control unit 12 can also check the status of each component of the aerosol generator 1 and determine whether the aerosol generator 1 is operational.

[0029] The control unit 12 comprises at least one processor. The processor may be embodied as an array of numerous logic gates, or as a combination of a general-purpose microprocessor and memory in which a program executed by the microprocessor is stored. Those skilled in the art will understand that it may also be embodied as other forms of hardware.

[0030] The heater 13 is heated by power supplied from the battery 11. For example, when a cigarette is inserted into the aerosol generator 1, the heater 13 is located outside the cigarette. Therefore, the heated heater 13 raises the temperature of the aerosol-generating substance inside the cigarette.

[0031] The heater 13 may be an electrical resistance heater. For example, the heater 13 may have an electrical conductive track, and an electric current may flow through the electrical conductive track to heat the heater 13. However, the heater 13 is not limited to the above example and can be used without restriction as long as it can be heated to a desired temperature. Here, the desired temperature may already be set in the aerosol generator 1, or it may be set to a desired temperature by the user.

[0032] On the other hand, as another example, the heater 13 may be an induction heater. Specifically, the heater 13 includes an electrically conductive coil for heating the cigarette by induction heating, and the cigarette includes a susceptor that is heated by the induction heater.

[0033] For example, the heater 13 includes a tubular heating element, a plate-shaped heating element, a needle-shaped heating element, or a rod-shaped heating element, and heats the inside or outside of the cigarette 2 depending on the shape of the heating element.

[0034] Furthermore, the aerosol generator 1 may have multiple heaters 13. In this case, the multiple heaters 13 may be arranged so as to be inserted inside the cigarette 2, or they may be arranged outside the cigarette 2. Alternatively, some of the multiple heaters 13 may be arranged so as to be inserted inside the cigarette 2, and the rest may be arranged outside the cigarette 2. Also, the shape of the heaters 13 is not limited to the shapes shown in Figures 1 to 3, and they may be manufactured in a variety of shapes.

[0035] The vaporizer 14 heats the liquid composition to generate an aerosol, which is then delivered to the user through the cigarette 2. In other words, the aerosol generated by the vaporizer 14 travels along the airflow passage of the aerosol generator 1, which is configured so that the aerosol generated by the vaporizer 14 is delivered to the user through the cigarette.

[0036] For example, the vaporizer 14 includes a liquid storage unit, a liquid transfer means, and a heating element, but is not limited to these. For instance, the liquid storage unit, liquid transfer means, and heating element may be provided in the aerosol generator 1 as independent modules.

[0037] The liquid storage unit stores a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing substance that includes volatile tobacco flavor components, or a liquid containing a non-tobacco substance. The liquid storage unit may be manufactured to be detachable from the vaporizer 14, or it may be manufactured integrally with the vaporizer 14.

[0038] For example, a liquid composition may include water, solvent, ethyl alcohol, plant extracts, fragrances, flavoring agents, or vitamin mixtures. Fragrances may include, but are not limited to, menthol, peppermint, spearmint oil, and various fruit fragrance components. Flavoring agents may include components that provide users with a variety of flavors or aromas. Vitamin mixtures may be, but are not limited to, a mixture of at least one of vitamins A, B, C, and E. Furthermore, a liquid composition may include aerosol-forming agents such as glycerin and propylene glycol.

[0039] The liquid transfer means transfers the liquid composition of the liquid storage section to the heating element. For example, the liquid transfer means may be, but is not limited to, a wick made of cotton fibers, ceramic fibers, glass fibers, or porous ceramics.

[0040] The heating element is an element for heating the liquid composition transmitted by the liquid transmission means. For example, the heating element may be, but is not limited to, a metal heating wire, a metal heating plate, or a ceramic heater. The heating element may also be composed of a conductive filament such as a nichrome wire, or it may be arranged in a structure that is wound around the liquid transmission means. The heating element is heated by the supply of electric current, and heat is transferred to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, an aerosol is generated.

[0041] For example, the steam maker 14 is called a cartomizer or atomizer, but is not limited to these terms.

[0042] On the other hand, the aerosol generator 1 may further include general-purpose components in addition to the battery 11, control unit 12, heater 13, and vaporizer 14. For example, the aerosol generator 1 may include a display capable of outputting visual information and / or a motor for outputting tactile information. The aerosol generator 1 may also include at least one sensor (such as a puff detection sensor, a temperature detection sensor, or a cigarette insertion detection sensor). Furthermore, the aerosol generator 1 may be constructed in such a way that outside air flows in or internal gas flows out even when a cigarette 2 is inserted.

[0043] Although not shown in Figures 1 to 3, the aerosol generator 1 may be configured with a separate cradle. For example, the cradle is used to charge the battery 11 of the aerosol generator 1. Alternatively, the heater 13 is heated while the cradle and the aerosol generator 1 are coupled together.

[0044] Cigarette 2 is similar to a typical combustible cigarette. For example, Cigarette 2 is divided into a first part containing an aerosol-generating substance and a second part containing a filter, etc. Alternatively, the second part of Cigarette 2 may also contain an aerosol-generating substance. For example, an aerosol-generating substance made in the form of granules or capsules may be inserted into the second part.

[0045] The entire first part is inserted into the aerosol generator 1, while the second part is exposed to the outside. Alternatively, only a portion of the first part may be inserted into the aerosol generator 1, or both the entire first part and a portion of the second part may be inserted. The user inhales the aerosol with the second part in their mouth. At this time, the aerosol is generated as outside air passes through the first part, and the generated aerosol is transmitted to the user's mouth by passing through the second part.

[0046] As an example, outside air flows in through at least one air passage formed in the aerosol generator 1. For example, the opening and closing of the air passage formed in the aerosol generator 1 and / or the size of the air passage can be adjusted by the user. This allows the amount of atomization, the smoking sensation, etc., to be adjusted by the user. As another example, outside air flows into the cigarette 2 through at least one hole formed on the surface of the cigarette 2.

[0047] The following example of cigarette 2 will be explained with reference to Figures 4 and 5.

[0048] Figures 4 and 5 are diagrams showing examples of cigarettes.

[0049] Referring to Figure 4, cigarette 2 comprises a tobacco rod 210 and a filter rod 220. Referring to Figures 1 to 3, the first part described above comprises the tobacco rod 210, and the second part comprises the filter rod 220.

[0050] Figure 4 shows the filter rod 220 as a single segment, but it is not limited to this. In other words, the filter rod 220 may consist of multiple segments. For example, the filter rod 220 may include a segment for cooling the aerosol and a segment for filtering out predetermined components contained in the aerosol. Alternatively, the filter rod 220 may further include at least one segment that performs other functions, as needed.

[0051] The diameter of the cigarette 2 is within the range of 5 mm to 9 mm, and the length is approximately 48 mm, but is not limited to these dimensions. For example, the length of the tobacco rod 210 is approximately 12 mm, the length of the first segment of the filter rod 220 is approximately 10 mm, the length of the second segment of the filter rod 220 is approximately 14 mm, and the length of the third segment of the filter rod 220 is approximately 12 mm, but is not limited to these dimensions.

[0052] The cigarette 2 is packaged by at least one flaps 240. The flaps 240 have at least one hole through which outside air enters or internal gases exit. As an example, the cigarette 2 is packaged by one flaps 240. As another example, the cigarette 2 may be packaged in layers by two or more flaps 240. For example, the tobacco rod 210 is packaged by a first flaps 241, and the filter rod 220 is packaged by flaps 242, 243, and 244. The entire cigarette 2 is then repackaged by a single flaps. If the filter rod 220 consists of multiple segments, each segment may be packaged by flaps 242, 243, and 244.

[0053] The first and second flaps 241 and 242 are made from general filter wrapping paper. For example, the first and second flaps 241 and 242 are made from porous or non-porous wrapping paper. Alternatively, the first and second flaps 241 and 242 may be made from oil-resistant paper and / or aluminum-laminated wrapping materials.

[0054] The third flap 243 may be made of hard-wound paper. For example, the basis weight of the third flap 243 may be 88 g / m². 2 or 96g / m 2 It is included within the range, preferably 90 g / m². 2 or 94g / m 2 It falls within the specified range. Furthermore, the thickness of the third flank 243 is within the range of 120 μm to 130 μm, preferably 125 μm.

[0055] The fourth flap 244 is made from oil-resistant hard-wrapped paper. For example, the basis weight of the fourth flap 244 is 88 g / m². 2 or 96g / m 2 It is included within the range, preferably 90 g / m². 2 or 94g / m 2 It falls within the specified range. Furthermore, the thickness of the fourth flank 244 falls within the range of 120 μm to 130 μm, preferably 125 μm.

[0056] The fifth wrapper 245 can be made of sterilized paper (MFW). Here, the sterilized paper (MFW) refers to paper that is specially manufactured so that its tensile strength, water resistance, smoothness, etc. are improved compared to ordinary paper. For example, the basis weight of the fifth wrapper 245 is included within the range of 57 g / m 2 to 63 g / m 2 and preferably is 60 g / m 2 . Also, the thickness of the fifth wrapper 245 is included within the range of 64 μm to 70 μm and preferably is 67 μm.

[0057] The fifth wrapper 245 is incorporated with a predetermined substance. Here, examples of the predetermined substance include, but are not limited to, silicon. For example, silicon has properties such as heat resistance with little change due to temperature, oxidation resistance that is not oxidized, resistance to various chemicals, water repellency to water, or electrical insulation. However, even if it is not silicon, as long as it is a substance having the above-described properties, it can be applied (or coated) to the fifth wrapper 245 without limitation.

[0058] The fifth wrapper 245 prevents the phenomenon of the cigarette 2 being combusted. For example, if the tobacco rod 210 is heated by the heater 13, there is a possibility that the cigarette 2 will be combusted. Specifically, if any one of the substances contained in the tobacco rod 310 is heated to above the ignition point, there is a risk that the cigarette 2 will be combusted. Even in such a case, since the fifth wrapper 245 contains a non-combustible substance, the phenomenon of the cigarette 2 being combusted is prevented.

[0059] Also, the fifth wrapper 245 prevents the holder from being contaminated by the substances generated by the cigarette 2. Depending on the puff of the user, a liquid substance is generated inside the cigarette 2. For example, when the aerosol generated by the cigarette 2 is cooled by the outside air, a liquid substance (such as moisture, etc.) is generated. By the fifth wrapper 245 packaging the cigarette 2, it is possible to prevent the liquid substance generated inside the cigarette 2 from leaking outside the cigarette 2.

[0060] The tobacco rod 210 contains an aerosol-generating substance. For example, the aerosol-generating substance includes, but is not limited to, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. The tobacco rod 210 may also contain other additives such as flavoring agents, humectants, and / or organic acids. Furthermore, a flavoring liquid such as menthol or a humectant may be added to the tobacco rod 210 by spraying it.

[0061] The tobacco rod 210 can be manufactured in various ways. For example, the tobacco rod 210 may be made from a sheet or from a strand. Alternatively, the tobacco rod 210 may be made from shredded tobacco obtained by cutting a tobacco sheet. The tobacco rod 210 may also be surrounded by a heat conductive material. For example, the heat conductive material may be a metal foil such as aluminum foil, but is not limited to this. As an example, the heat conductive material surrounding the tobacco rod 210 evenly distributes the heat transferred to the tobacco rod 210, improving the thermal conductivity applied to the tobacco rod and thereby improving the tobacco flavor. The heat conductive material surrounding the tobacco rod 210 also functions as a susceptor heated by an induction heater. Although not shown in the drawings, the tobacco rod 210 may also have a susceptor in addition to the heat conductive material surrounding its exterior.

[0062] The filter rod 220 may be a cellulose acetate filter. On the other hand, there are no restrictions on the shape of the filter rod 220. For example, the filter rod 220 may be a cylindrical rod, or a tubular rod containing a hollow inside. The filter rod 220 may also be a recessed rod. If the filter rod 220 is composed of multiple segments, at least one of the segments will be manufactured in a different shape.

[0063] The first segment of the filter rod 220 is also a cellulose acetate filter. For example, the first segment is a tubular structure containing a hollow interior. When the heater 13 is inserted along the first segment, it prevents the internal material of the tobacco rod 210 from being pushed backward, and also generates an aerosol cooling effect. The diameter of the hollow interior of the first segment is a suitable diameter within the range of 2 mm to 4.5 mm, but is not limited to these values.

[0064] The length of the first segment can be any length appropriate within the range of 4 mm to 30 mm, but is not limited to these. Preferably, the length of the first segment is 10 mm, but is not limited to these.

[0065] The hardness of the first segment is adjusted by controlling the plasticizer content during its manufacture. The first segment is also manufactured by inserting a structure such as a film or tube of the same or different material into its interior (for example, hollow).

[0066] The second segment of the filter rod 220 cools the aerosol generated when the heater 13 heats the tobacco rod 210. Thus, the user can inhale the aerosol cooled to a suitable temperature.

[0067] The distance or diameter of the second segment is determined in various ways depending on the form of cigarette 2. For example, the length of the second segment is appropriately taken within the range of 7 mm to 20 mm. Preferably, the length of the second segment is 14 mm, but it is not limited to this.

[0068] The second segment is produced by weaving polymer fibers. In this case, a fragrance solution may be applied to the polymer fibers. Alternatively, the second segment may be produced by weaving together a separate fiber coated with a fragrance solution and a polymer fiber. Alternatively, the second segment is formed from a rolled polymer sheet.

[0069] For example, polymers are made from materials selected from the group consisting of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polylactic acid (PLA), cellulose acetate (CA), and aluminum foil.

[0070] The second segment is formed from woven polymer fibers or a crimped polymer sheet, and the second segment comprises one or more longitudinally extending channels, where the channels represent passages through which a gas (e.g., air or aerosol) passes.

[0071] For example, the second segment, which consists of a rolled polymer sheet, is formed from a material with a thickness between approximately 5 μm and approximately 300 μm, for example, between approximately 10 μm and approximately 250 μm. The total surface area of ​​the second segment is approximately 300 mm². 2 / mm and approximately 1000mm 2 It falls between / mm. Furthermore, the aerosol cooling element has a specific surface area of ​​approximately 10mm². 2 / mg and approximately 100mm 2 Formed from materials between / mg

[0072] On the other hand, the second segment contains threads containing volatile flavor components. Here, the volatile flavor component is menthol, but is not limited to menthol. For example, the threads are filled with a sufficient amount of menthol to provide 1.5 mg or more of menthol to the second segment.

[0073] The third segment of the filter rod 220 is also a cellulose acetate filter. The length of the third segment is appropriately chosen within the range of 4 mm to 20 mm. For example, the length of the third segment may be 12 mm, but it is not limited to these values.

[0074] The third segment may be manufactured in such a way that flavor is generated by spraying a flavoring liquid onto it during the manufacturing process. Alternatively, a separate fiber coated with a flavoring liquid may be inserted into the third segment. The aerosol generated in the tobacco rod 210 is cooled by passing through the second segment of the filter rod 220, and the cooled aerosol is transmitted to the user through the third segment. Therefore, when a flavoring element is added to the third segment, the effect of improving the persistence of the flavor transmitted to the user occurs.

[0075] Furthermore, the filter rod 220 includes at least one capsule 230. Here, the capsule 230 may perform a function of generating flavor or a function of generating an aerosol. For example, the capsule 230 has a structure in which a liquid containing a flavor is enclosed in a film. The capsule 230 may be spherical or cylindrical, but is not limited to these.

[0076] Referring to Figure 5, the cigarette 3 further comprises a front plug 330. The front plug 330 is located on one side of the tobacco rod 310 opposite the filter rod 320. The front plug 330 prevents the tobacco rod 310 from detaching to the outside and prevents liquefied aerosol from flowing from the tobacco rod 310 into the aerosol generator (Figures 1 to 3-1) during smoking.

[0077] The filter rod 320 comprises a first segment 321 and a second segment 322. Here, the first segment 321 corresponds to the first segment of the filter rod 220 in Figure 4, and the second segment 322 corresponds to the third segment of the filter rod 220 in Figure 4.

[0078] The diameter and overall length of cigarette 3 correspond to the diameter and overall length of cigarette 2 in Figure 4. For example, the length of the front plug 330 is approximately 7 mm, the length of the tobacco rod 310 is approximately 15 mm, the length of the first segment 321 is approximately 12 mm, and the length of the second segment 322 is approximately 14 mm, but these are not limited to these dimensions.

[0079] The cigarette 3 is packaged by at least one flap 350. The flap 350 has at least one hole through which outside air enters or internal gases exit. For example, the front plug 330 is packaged by a first flap 351, the tobacco rod 310 is packaged by a second flap 352, the first segment 321 is packaged by a third flap 353, and the second segment 322 is packaged by a fourth flap 354. The entire cigarette 3 is then repackaged by a fifth flap 355.

[0080] Furthermore, at least one perforation 36 is formed in the fifth trumpet 355. For example, the perforation 36 is formed in the region surrounding the tobacco rod 310, but is not limited to this. The perforation 36 serves to transfer the heat generated by the heater 13 shown in Figures 2 and 3 into the interior of the tobacco rod 310.

[0081] Furthermore, the second segment 322 includes at least one capsule 340. Here, the capsule 340 may perform a function to generate flavor or a function to generate an aerosol. For example, the capsule 340 has a structure in which a liquid containing a flavor is enclosed in a film. The capsule 340 may be spherical or cylindrical, but is not limited to these.

[0082] The first wrapper 351 is made of a general filter wrapping paper bonded with a metal foil such as aluminum foil. For example, the overall thickness of the first wrapper 351 is in the range of 45 μm to 55 μm, preferably 50.3 μm. The thickness of the metal foil of the first wrapper 351 is in the range of 6 μm to 7 μm, preferably 6.3 μm. The basis weight of the first wrapper 351 is 50 g / m². 2 or 55g / m 2 It falls within the range, preferably 53 g / m². 2 That is the case.

[0083] The second and third wrappers 352 and 353 are made from common filter paper. For example, the second and third wrappers 352 and 353 are made from porous or non-porous paper.

[0084] For example, the porosity of the second flank 352 is 35,000 CU, but is not limited to this. The thickness of the second flank 352 is within the range of 70 μm to 80 μm, preferably 78 μm. The basis weight of the second flank 352 is 20 g / m². 2 or 25g / m 2 It falls within the range, preferably 23.5 g / m². 2 That is the case.

[0085] For example, the porosity of the third flank 353 is 24,000 CU, but is not limited to this. The thickness of the third flank 353 is within the range of 60 μm to 70 μm, preferably 68 μm. The basis weight of the third flank 353 is 20 g / m². 2 or 25g / m 2 It is included within the range, preferably 21 g / m² 2 That is the case.

[0086] The fourth flank 354 is made of PLA laminate. Here, PLA laminate means a triple layer of paper including a paper layer, a PLA layer, and another paper layer. For example, the thickness of the fourth flank 354 is within the range of 100 μm to 120 μm, preferably 110 μm. The basis weight of the fourth flank 354 is 80 g / m². 2 or 100g / m 2 It falls within the range, preferably 88 g / m² 2 That is the case.

[0087] The fifth trumpet 355 is made from sterile paper (MFW). Here, sterile paper (MFW) refers to paper specially manufactured to have improved tensile strength, water resistance, smoothness, etc., compared to ordinary paper. For example, the basis weight of the fifth trumpet 355 is 57 g / m². 2 or 63g / m 2 It is included within the range, preferably 60 g / m². 2 Furthermore, the thickness of the fifth flank 355 is within the range of 64 μm to 70 μm, preferably 67 μm.

[0088] The fifth trumpet 355 is infused with a predetermined substance. While silicon is an example of such a substance, it is not limited to silicon. For instance, silicon possesses properties such as heat resistance (minimal change with temperature), oxidation resistance (no oxidation), resistance to various chemicals, water repellency, and electrical insulation. However, any substance possessing the aforementioned properties, even if not silicon, may be applied (or coated) to the fifth trumpet 355 without limitation.

[0089] The front plug 330 is made of cellulose acetate. For example, the front plug 330 is made by adding a plasticizer (e.g., triacetin) to a cellulose acetate tow. The mono denier of the filament constituting the cellulose acetate tow is in the range of 1.0 to 10.0, preferably in the range of 4.0 to 6.0. More preferably, the mono denier of the filament of the front plug 330 is 5.0. The cross-section of the filament constituting the front plug 330 is also Y-shaped. The total denier of the front plug 330 is in the range of 20,000 to 30,000, preferably in the range of 25,000 to 30,000. More preferably, the total denier of the front plug 330 is 28,000.

[0090] Furthermore, if necessary, the front plug 330 includes at least one channel, and the cross-sectional shape of the channel can be manufactured in a variety of ways.

[0091] The tobacco rod 310 corresponds to the tobacco rod 210 mentioned above, as shown in Figure 4. Therefore, a detailed explanation of the tobacco rod 310 will be omitted below.

[0092] The first segment 321 is made of cellulose acetate. For example, the first segment is a tubular structure containing a hollow interior. The first segment 321 is made by adding a plasticizer (e.g., triacetin) to cellulose acetate tow. For example, the monodenier and total denier of the first segment 321 are the same as the monodenier and total denier of the front plug 330.

[0093] The second segment 322 is made of cellulose acetate. The monodenier of the filaments constituting the second segment 322 is in the range of 1.0 to 10.0, preferably in the range of 8.0 to 10.0. More preferably, the monodenier of the filaments of the second segment 322 is 9.0. The cross-section of the filaments of the second segment 322 is Y-shaped. The total denier of the second segment 322 is in the range of 20,000 to 30,000, preferably 25,000.

[0094] Figure 6A is a drawing showing the external appearance of an aerosol generating device according to one embodiment.

[0095] Referring to Figure 6A, the aerosol generating device 1 according to one embodiment comprises a main body 110 and an external cover 120 coupled to the main body 110.

[0096] The outer cover 120 is coupled to a portion of the main body 110 to protect the components of the aerosol generator 1 that are placed on the main body 110. The coupled main body 110 and outer cover 120 form the overall appearance of the aerosol generator 1. The main body 110 and the outer cover 120 are either bonded to each other and inseparable, or they are coupled detachably by coupling means such as coupling grooves, but the coupling method can be implemented in various ways.

[0097] As will be described later, the components of the aerosol generator 1, excluding the circuit layer 121 included in the outer cover 120, are included in the main body 110. For example, the main body 110 may include, but is not limited to, a storage space into which a cigarette can be inserted, a heater for heating the cigarette, and a user interface (e.g., a USB interface) for electrically connecting the aerosol generator 1 to an external device.

[0098] Figure 6B is a schematic diagram showing the position where the circuit layer 121 is attached to the outer cover of an aerosol generating device according to one embodiment.

[0099] Figure 6B shows only a portion of the external cover 120. The external cover 120 includes a circuit layer 121, a base layer, a light-transmitting layer, a shielding layer, and a coating layer 125 arranged sequentially from the back to the front of the external cover 120, and one or more light-emitting members 121a placed on the circuit layer 121. However, in Figure 6B, the components other than the circuit layer 121, light-emitting members 121a, and coating layer 125 are omitted in order to schematically show the position where the circuit layer 121 is attached to the external cover 120.

[0100] Referring to Figure 6B, the front surface of the outer cover 120 includes a coating layer 125, which indicates the appearance of the outer cover 120. The coating layer 125 indicates the hue of the front surface of the outer cover 120. The coating layer 125 may also indicate the texture of the outer cover 120.

[0101] In one embodiment, the coating layer 125 further includes a hard coating layer to increase the strength of the outer cover 120 and protect its surface. In this case, the hard coating layer is made of a transparent material so that the hue of the coating layer 125 is visible on the front surface of the outer cover 120.

[0102] Referring to Figure 6B, the circuit layer 121 includes one or more light-emitting members 121a. Light emitted from the light-emitting members 121a is transmitted toward the front surface of the outer cover 120. The circuit layer 121 on which the one or more light-emitting members 121a are arranged is located on the back surface of the outer cover 120. The circuit layer 121 is formed by methods such as bonding it to the back surface of the outer cover 120 or transferring it to the back surface, but is not limited to these methods.

[0103] Figures 7 to 12 are schematic cross-sectional views of the external cover of an aerosol generating device according to one embodiment.

[0104] Figures 7 to 12 relate to various embodiments of the external cover 120 of the aerosol generator 1, and redundant explanations are omitted. It goes without saying that various embodiments described later with respect to Figure 7 are also applied to Figures 8 to 12.

[0105] Figure 7 is a cross-sectional view of the external cover 120 of the aerosol generating device 1 according to the first embodiment.

[0106] In one embodiment, the external cover 120 of the aerosol generating device 1 includes a configuration that emits light toward the front of the external cover 120. That is, the emitted light is displayed on the front of the external cover 120, which can be visually recognized by the user.

[0107] Specifically, the outer cover 120 includes a circuit layer 121, a base layer 122, a light-transmitting layer 123, a shielding layer 124, and a coating layer 125, which are arranged sequentially from the back to the front of the outer cover 120.

[0108] The circuit layer 121 includes one or more light-emitting members 121a disposed on the circuit layer 121. The base layer 122, the light-transmitting layer 123, the shielding layer 124, and the coating layer 125 include light-transmitting materials.

[0109] Light emitted from the light-emitting member 121a placed in the circuit layer 121 is transmitted through the base layer 122, the light-transmitting layer 123, the shielding layer 124, and the coating layer 125 in that order, and is displayed on the front surface of the outer cover 120.

[0110] The external cover 120 has a circuit layer 121 on its back surface that includes a light-emitting element 121a, which reduces the distance between the position from which light is emitted from the light-emitting element 121a and the position from which the emitted light is transmitted and displayed. As a result, the phenomenon of light appearing uneven due to positional deviation can be reduced.

[0111] A base layer 122 is placed on the circuit layer 121, a light-transmitting layer 123 is placed on the base layer 122, a shielding layer 124 is placed on the light-transmitting layer 123, and a coating layer 125 is placed on the shielding layer 124. The coating layer 125 constitutes the front surface of the outer cover 120. That is, the base layer 122, light-transmitting layer 123, shielding layer 124, and coating layer 125 are arranged sequentially in the front direction of the circuit layer 121, which coincides with the front direction of the outer cover 120.

[0112] The light-emitting member 121a includes a light source. The light source is, for example, an LED (Light Emitting Diode), but is not limited to this, and may include other light sources such as lamps. The light-emitting member 121a is positioned on the back or front of the circuit layer 121.

[0113] Light emitted from the light-emitting member 121a is transmitted to the front of the outer cover 120. Specifically, the light emitted from the light-emitting member 121a is transmitted in the following order: base layer 122, light-transmitting layer 123, shielding layer 124, and coating layer 125.

[0114] One or more light-emitting members 121a provide various information to the front of the external cover 120 by partially or completely lighting up or turning off. The light-emitting members 121a also provide various information through changes in the intensity and hue of the light they emit.

[0115] The light-emitting member 121a displays the operating status of the aerosol generator 1 by emitting light in one of several predetermined hues. For example, the system is set so that the hue of the light emitted from the light-emitting member 121a changes as the temperature of the aerosol generator 1 rises during preheating, and such a change in hue is displayed on the front of the external cover 120 so that the user can visually recognize it. However, this is not limited to this, and includes any embodiment that can inform the user. The operation of the light-emitting member 121a is controlled by a control unit (not shown).

[0116] The circuit layer 121 is located on the outermost side of the back of the outer cover 120, and when the main body 110 and the outer cover 120 are joined, the circuit layer 121 and the main body 110 come into contact. However, other components such as a protective film may be included in the direction of the back of the circuit layer 121, which coincides with the direction of the back of the outer cover 120.

[0117] The circuit layer 121 is a PCB (Printed Circuit Board) or FPCB (Flexible Printed Circuit Board), and the light-emitting element 121a is mounted on the circuit layer 121. However, the arrangement and installation method of the light-emitting element 121a are not limited. The circuit layer 121 also includes at least one electrical connector (not shown) for electrically connecting to the light-emitting element 121a, a control unit (not shown), etc.

[0118] As an example, the base layer 122 is placed on the circuit layer 121 and is formed to be transparent or semi-transparent so as to allow light to pass through. Base layer 122 It is composed of a material that transmits light with a predetermined transmittance. Specifically, a translucent material is one in which the light transmittance exceeds 0% but is less than 100%.

[0119] More specifically, the material of the base layer 122 includes glass, or plastic materials such as polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), and polycarbonate (PC). However, it is not limited to these, and may be composed of other materials.

[0120] The base layer 122 serves as a base for laminating the light-transmitting layer 123, the shielding layer 124, and the coating layer 125, and provides rigidity to the outer cover 120.

[0121] As an example, in order to secure the arrangement of the circuit layer 121 and the base layer 122, a support member 121c is further included between the circuit layer 121 and the base layer 122. The support member 121c may be formed separately from the circuit layer 121 and the base layer 122, or it may be formed integrally with the circuit layer 121, or it may be formed integrally with the base layer 122.

[0122] The support member 121c is positioned between the circuit layer 121 and the base layer 122, preventing the light-emitting member 121a and other components (not shown) of the circuit layer 121 from coming into contact with the base layer 122. The support member 121c is formed in a portion of the circuit layer 121 where no components are placed, or is formed to abut against a portion where no components are placed, thereby creating a space 121b between the circuit layer 121 and the base layer 122. Through this space 121b, light emitted from the light-emitting member 121a is transmitted towards the base layer 122. In one embodiment, the surface of the support member 121c that abuts against the space 121b has the property of reflecting light.

[0123] As an example, the light-transmitting layer 123 is placed on the base layer 122. Light emitted from the light-emitting member 121a passes through the base layer 122 and then through the light-transmitting layer 123. The light-transmitting layer 123 contains a light-transmitting material.

[0124] The light-transmitting layer 123 includes one or more light-transmitting portions 123a that can transmit light and one or more light-blocking portions 123b that can block light. That is, the light-transmitting portions 123a can have an even higher light transmittance than the light-blocking portions 123b.

[0125] The light-transmitting portion 123a is formed at a position through which light emitted from the light-emitting member 121a is transmitted.

[0126] For example, multiple light-emitting members 121a may be formed at positions corresponding to multiple light-transmitting portions 123a, or multiple light-transmitting portions 123a may be formed at positions corresponding to one light-emitting member 121a. Alternatively, one light-transmitting portion 123a may be formed at a position corresponding to multiple light-emitting members 121a, and it goes without saying that a variety of combinations are possible in the aforementioned arrangements.

[0127] Furthermore, the light emitted from the light-emitting member 121a is adjusted to travel along a desired path through reflection, refraction, etc., and one or more light-transmitting parts 123a are placed along the adjusted path of the light.

[0128] The translucent layer 123 is formed by printing on the base layer 122 using a printing process such as screen printing or other transfer processes.

[0129] The light-blocking portion 123b blocks the light emitted from the light-emitting member 121a and is printed using colored ink. The ink is black or other colored. The color of the ink is the same as or similar to the color of the shielding layer 124 or the coating layer 125.

[0130] The light-transmitting portion 123a transmits light emitted from the light-emitting member 121a and is the remaining portion of the light-transmitting layer 123 in which the light-blocking portion 123b is not formed. The light-transmitting portion 123a is formed at a position corresponding to the light-emitting member 121a. Therefore, when the light-emitting member 121a emits light, the light-transmitting portion 123a transmits the light, exposing the light to the outside.

[0131] The light-transmitting portion 123a is the remaining area excluding the light-blocking portion 123b. The light-transmitting portion 123a is a perforated hole or is formed of a light-transmitting material. The light-blocking portion 123b is formed by printing a light-blocking material, and the light-transmitting portion 123a is formed in an area where the light-blocking material is not printed, so that the light-transmitting portion 123a is manufactured to have the aforementioned holes. The light-transmitting material is, for example, a urethane resin.

[0132] Each light-transmitting portion 123a can have a variety of sizes and shapes, for example, circular or polygonal.

[0133] The light-transmitting portion 123a transmits light emitted from the light-emitting member 121a, exposing it to the front surface of the outer cover 120 for user observation. Specifically, the light emitted from the light-emitting member 121a is transmitted in the following order: base layer 122, light-transmitting portion 123a of the light-transmitting layer 123, shielding layer 124, and coating layer 125, and is observed by the user.

[0134] By turning on or off one or more light-emitting elements 121a, the multiple light-transmitting sections 123a display pictures, numbers, letters, etc., on the front surface of the outer cover 120.

[0135] As an example, the shielding layer 124 is placed on the light-transmitting layer 123. When the light-emitting member 121a is off, the light-transmitting portion 123a is shielded by the shielding layer 124, and when observed from the front of the outer cover 120, the light-transmitting portion 123a is not visible.

[0136] The shielding layer 124 allows light emitted from the light-emitting member 121a when the light-emitting member 121a is lit to pass through toward the front surface of the outer cover 120, and when the light-emitting member 121a is turned off, it shields the light-transmitting portion 123a so that it cannot be seen from the front surface of the outer cover 120. In other words, the shielding layer 124 allows light emitted from the light-emitting member 121a to pass through to the outside (i.e., toward the front), but prevents light incident from the outside from passing through to the inside (i.e., toward the back).

[0137] The shielding layer 124 prevents the user from recognizing the internal structure of the light-emitting element 121a or the light-transmitting section 123a that transmits light emitted from the light-emitting element 121a, and only allows them to perceive the light transmitted from the light-emitting element 121a to the front surface of the outer cover 120. This implementation improves the design effect.

[0138] The shielding layer 124 is in the form of a very thin metallic layer. For example, it is formed by printing metallic ink or applying a semi-permeable spray. However, it may be embodied by other materials with adjustable transmittance, but is not limited to these.

[0139] As an example, the coating layer 125 is placed on the shielding layer 124. The coating layer 125 forms the appearance of the front surface of the outer cover 120 of the aerosol generating device 1. The coating layer 125 forms the hue, texture, etc. of the front surface of the outer cover 120. The coating layer 125 is formed, for example, by film transfer.

[0140] The coating layer 125 includes a light-transmitting material. Light emitted from the light-emitting member 121a is transmitted through the base layer 122, the light-transmitting layer 123, the shielding layer 124, and the coating layer 125 in that order, and is displayed on the front surface of the outer cover 120. The front surface of the outer cover 120 is the front surface of the coating layer 125.

[0141] As an example, in order to enhance the surface hardness of the front surface of the outer cover 120 and improve its durability, the coating layer 125 further includes a hard coating layer with high hardness.

[0142] Figure 8 is a cross-sectional view of the external cover 120 of the aerosol generating device 1 according to the second embodiment.

[0143] As explained with reference to Figure 7, the circuit layer 121 and light-emitting member 121a, base layer 122, light-transmitting layer 123, shielding layer 124, coating layer 125, etc. shown in Figure 8 are the same as the components described above, so a redundant explanation will be omitted.

[0144] As described above, the light-transmitting layer 123 includes one or more light-transmitting portions 123a that can transmit light and one or more light-blocking portions 123b that can block light. The light-transmitting portions 123a are formed at positions through which light emitted from the light-emitting member 121a is transmitted.

[0145] Referring to Figure 8, multiple light-transmitting sections 123a are formed at positions through which light emitted from a single light-emitting member 121a is transmitted.

[0146] In Figure 8, assuming that the path of light emitted from one light-emitting member 121a does not overlap with the path of light emitted from other light-emitting members 121a, the light emitted from one light-emitting member 121a is arranged to pass through two light-transmitting sections 123a, the light emitted from another light-emitting member 121a is arranged to pass through three light-transmitting sections 123a, and the light emitted from yet another light-emitting member 121a is arranged to pass through five light-transmitting sections 123a.

[0147] The number, spacing, and size of the light-transmitting sections 123a can be varied. By suitably setting the number, spacing, and size of the light-transmitting sections 123a, it is possible to form at least one shape from among pictures, letters, numbers, and symbols. In other words, the light-transmitting sections 123a transmit light emitted from one or more of the light-emitting members 121a, and the light transmitted through the light-transmitting sections 123a reaches the front surface of the outer cover 120, allowing the user to recognize at least one shape from among pictures, letters, numbers, and symbols.

[0148] Figure 9 is a drawing showing a cross-section of the external cover 120 of the aerosol generating device 1 according to the third embodiment.

[0149] Referring to Figure 9, unlike the embodiments in Figures 7 and 8, it includes a light-diffusing layer 126 positioned between the circuit layer 121 and the base layer 122. The remaining circuit layer 121 and light-emitting member 121a, base layer 122, light-transmitting layer 123, shielding layer 124, coating layer 125, etc., are the same as the components described above, so a redundant explanation will be omitted.

[0150] The light diffusion layer 126 is positioned between the circuit layer 121 and the base layer 122 and guides the light emitted from the light-emitting member 121a so that it is transmitted to the light-transmitting portion 123a. The light diffusion layer 126 includes one or more light-guiding portions 126a and one or more light-reflecting portions 126b.

[0151] The light guide portion 126a transmits light emitted from the light-emitting member 121a, and the light reflecting portion 126b reflects light emitted from the light-emitting member 121a. By including the light guide portion 126a and the light reflecting portion 126b, light can be concentrated towards the light-transmitting portion 123a of the light-transmitting layer 123. As a result, relatively bright light can be displayed even with a small amount of light, and relatively less power can be used when the light-emitting member 121a emits light.

[0152] The light-reflecting portion 126b is formed of a light-reflecting material, or contains a light-reflecting material only in the portion that contacts the light-guiding portion 126a. If the light-reflecting portion 126b contains a light-reflecting material only in a portion of it, the rest is filled with a light-impermeable material, so that the light emitted from the light-emitting member 121a is transmitted only through the light-guiding portion 126a.

[0153] Figure 10 is a drawing showing a cross-section of the external cover 120 of the aerosol generating device 1 according to the fourth embodiment.

[0154] Referring to Figure 10, the optical guide portion 126a includes a shape in which its size gradually increases from the circuit layer 121 to the base layer 122. This shape allows light to be further concentrated towards the light-transmitting portion 123a of the light-transmitting layer 123. When the optical guide portion 126a has the shape shown in Figure 10, the light-reflecting portion 126b includes a shape in which its size gradually decreases relative to the circuit layer 121 to the base layer 122. However, its shape is not limited as long as the aforementioned objective can be achieved.

[0155] Figure 11 is a drawing showing a cross-section of the external cover 120 of the aerosol generating device 1 according to the fifth embodiment.

[0156] Referring to Figure 11, unlike the embodiments in Figures 7 to 10, the light-emitting member 121a is positioned on the back surface of the circuit layer 121. The remaining circuit layer 121, light-emitting member 121a, base layer 122, light-transmitting layer 123, shielding layer 124, coating layer 125, etc., are the same as the components described above, so a redundant explanation will be omitted.

[0157] Light emitted from the light-emitting member 121a, positioned on the back of the circuit layer 121, passes through the base layer 122, the light-transmitting layer 123, the shielding layer 124, and the coating layer 125, and is displayed on the front of the outer cover 120.

[0158] As shown in Figure 11, when the light-emitting member 121a is placed on the back surface of the circuit layer 121, the spacing between the circuit layer 121 and the base layer 122 can be reduced, thereby reducing positional deviations due to tolerances. In other words, the distance between the position from which light is emitted from the light-emitting member 121a and the position from which the emitted light is transmitted and displayed is reduced, thereby reducing the phenomenon in which light appears uneven due to positional deviations.

[0159] Figure 12 is a drawing showing a cross-section of the external cover 120 of the aerosol generating device 1 according to the sixth embodiment.

[0160] Referring to Figure 12, similar to the embodiment in Figure 11, the light-emitting member 121a is positioned on the back surface of the circuit layer 121. Also, unlike the embodiment in Figure 11, it includes a light-diffusing layer 126 positioned between the circuit layer 121 and the base layer 122. The remaining circuit layer 121, light-emitting member 121a, base layer 122, light-transmitting layer 123, shielding layer 124, coating layer 125, etc., are the same as the components described above, so a redundant explanation will be omitted.

[0161] The light diffusion layer 126 is positioned between the circuit layer 121 and the base layer 122 and guides the light emitted from the light-emitting member 121a so that it is transmitted to the light-transmitting portion 123a. The light diffusion layer 126 includes one or more light-guiding portions 126a and one or more light-reflecting portions 126b.

[0162] The light guide portion 126a transmits light emitted from the light-emitting member 121a, and the light reflecting portion 126b reflects light emitted from the light-emitting member 121a. By including the light guide portion 126a and the light reflecting portion 126b, light can be concentrated towards the light-transmitting portion 123a of the light-transmitting layer 123. As a result, relatively bright light can be displayed even with a small amount of light, and relatively less power can be used when the light-emitting member 121a emits light.

[0163] The number and shape of the light guides 126a are not limited, as long as the light guides 126a can concentrate the light towards the light-transmitting portion 123a.

[0164] The external cover 120 for the aerosol generating apparatus 1 according to the above-described embodiment is manufactured by providing a base layer 122, sequentially laminating a light-transmitting layer 123, a shielding layer 124, and a coating layer 125 on the front surface of the base layer 122, and arranging a circuit layer 121 on the back surface of the base layer 122 on which one or more light-emitting members 121a are arranged. As described above, the base layer 122, the light-transmitting layer 123, the shielding layer 124, and the coating layer 125 include a light-transmitting material, and the light emitted from the light-emitting member 121a is transmitted in the order of the base layer 122, the light-transmitting layer 123, the shielding layer 124, and the coating layer 125.

[0165] As mentioned above, the light-transmitting layer 123 includes one or more light-transmitting portions 123a that transmit light and one or more light-blocking portions 123b that block light. In this case, the light-blocking portions 123b are formed by printing a light-blocking material, and the light-transmitting portions 123a are formed in areas where the light-blocking material is not printed, but it goes without saying that the method is not limited to these.

[0166] Furthermore, the step of placing the circuit layer 121 on the back surface of the base layer 122 includes the step of either adhering the circuit layer 121 to the back surface of the base layer 122 or forming the circuit layer 121 on the back surface of the base layer 122.

[0167] Specifically, bonding can be carried out using common bonding methods in the industry, such as using adhesives or adhesive tapes, or by fusion bonding. Placing the circuit layer 121 on the back of the base layer 122 may be done by directly transferring the circuit layer 121 to the back of the base layer 122, but is not limited to this.

[0168] Figure 13 is a block diagram of an aerosol generator 1300 according to another embodiment.

[0169] The aerosol generator 1300 comprises a control unit 1310, a sensing unit 1320, an output unit 1330, a battery 1340, a heater 1350, a user input unit 1360, a memory 1370, and a communication unit 1380. However, the internal structure of the aerosol generator 1300 is not limited to that shown in Figure 13. That is, a person skilled in the art will understand that depending on the design of the aerosol generator 1300, some of the components shown in Figure 13 may be omitted or new components may be added.

[0170] The sensing unit 1320 senses the state of the aerosol generator 1300 or the state of the area around the aerosol generator 1300 and transmits the sensed information to the control unit 1310. Based on the sensed information, the control unit 1310 controls the aerosol generator 1300 to perform various functions such as controlling the operation of the heater 1350, restricting smoking, determining whether or not to insert aerosol products (e.g., cigarettes, cartridges, etc.), and displaying notifications.

[0171] The sensing unit 1320 includes, but is not limited to, at least one of the temperature sensor 1322, insertion sensing sensor 1324, and puff sensor 1326.

[0172] The temperature sensor 1322 senses the temperature at which the heater 1350 (or the aerosol-generating material) is heated. The aerosol generator 1300 may have a separate temperature sensor that senses the temperature of the heater 1350, or the heater 1350 itself may act as the temperature sensor. Alternatively, the temperature sensor 1322 may be positioned around the battery 1340 to monitor the temperature of the battery 1340.

[0173] The insertion sensing sensor 1324 detects the insertion and / or removal of aerosol products. For example, the insertion sensing sensor 1324 includes at least one of a film sensor, a pressure sensor, a light sensor, a resistive sensor, a capacitive sensor, an inductive sensor, and an infrared sensor, and detects a signal change caused by the insertion and / or removal of aerosol products.

[0174] The puff sensor 1326 detects user puffs based on various physical changes in the airflow passage or airflow channel. For example, the puff sensor 1326 detects user puffs based on any one of the following: temperature changes, flow rate changes, voltage changes, and pressure changes.

[0175] In addition to the aforementioned sensors (temperature sensor 1322, insertion sensor 824, and puff sensor 1326), the sensing unit 1320 further includes at least one of the following: a temperature / humidity sensor, a pressure sensor, a magnetic sensor, an acceleration sensor, a gyroscope sensor, a position sensor (e.g., GPS), a proximity sensor, and an RGB sensor (illuminance sensor). The function of each sensor can be intuitively inferred by an average engineer from its name, so a detailed explanation is omitted.

[0176] The output unit 1330 outputs information about the status of the aerosol generator 1300 and provides it to the user. The output unit 1330 includes, but is not limited to, at least one of the display unit 1332, the haptic unit 1334, and the acoustic output unit 1336. When the display unit 1332 and the touchpad form a layered structure to constitute a touchscreen, the display unit 1332 is used not only as an output device but also as an input device.

[0177] The display unit 1332 visually provides the user with information about the aerosol generator 1300. For example, the information about the aerosol generator 1300 can include various types of information such as the charge / discharge status of the battery 1340 of the aerosol generator 1300, the preheating status of the heater 1350, the insertion / removal status of aerosol products, or conditions under which the use of the aerosol generator 1300 is restricted (e.g., detection of abnormal items), and the display unit 1332 outputs this information to the outside. The display unit 1332 can be, for example, a liquid crystal display panel (LCD), an organic light-emitting display panel (OLED), or an LED light-emitting element.

[0178] The haptic unit 1334 converts electrical signals into mechanical or electrical stimuli to provide the user with tactile information about the aerosol generator 1300. For example, the haptic unit 1334 may include a motor, a piezoelectric element, or an electrical stimulator.

[0179] The acoustic output unit 1336 provides the user with auditory information about the aerosol generator 1300. For example, the acoustic output unit 1336 converts electrical signals into acoustic signals and outputs them externally.

[0180] Battery 1340 supplies power used to operate the aerosol generator 1300. Battery 1340 also supplies power to heat the heater 1350. In addition, battery 1340 supplies power necessary for the operation of other components within the aerosol generator 1300 (e.g., sensing unit 1320, output unit 1330, user input unit 1360, memory 1370, and communication unit 1380). Battery 1340 is either a rechargeable battery or a disposable battery. For example, battery 1340 is a lithium polymer (LiPoly) battery, but is not limited to this.

[0181] The heater 1350 is powered by the battery 1340 to heat the aerosol-generating material. Although not shown in Figure 13, the aerosol generator 1300 may further include a power conversion circuit (e.g., a DC / DC converter) that converts the power from the battery 1340 and supplies it to the heater 1350. Also, if the aerosol generator 1300 generates aerosols using an induction heating method, the aerosol generator 1300 may further include a DC / AC converter that converts the DC power supply of the battery 1340 into AC power supply.

[0182] The control unit 1310, sensing unit 1320, output unit 1330, user input unit 1360, memory 1370, and communication unit 1380 are powered by the battery 1340 and perform their functions. Although not shown in Figure 13, the system further includes power conversion circuits, such as an LDO (low dropout) circuit or a voltage regulator circuit, that convert the power from the battery 1340 and supply it to each component.

[0183] In one embodiment, the heater 1350 is formed of any suitable electrical resistant material. For example, suitable electrical resistant materials include, but are not limited to, metals or metal alloys, including titanium, zirconium, tantalum, platinum, nickel, cobalt, chromium, hafnium, niobium, molybdenum, tungsten, tin, gallium, manganese, iron, copper, stainless steel, and nichrome. The heater 130 is also not limited to, but is embodied in a metal heating wire, a metal heating plate on which an electrically conductive track is arranged, or a ceramic heating element.

[0184] In other embodiments, the heater 1350 is an induction heating type heater. For example, the heater 1350 includes a susceptor that heats the aerosol-generating material by generating heat through a magnetic field applied by a coil.

[0185] The user input unit 1360 receives information input from the user or outputs information to the user. For example, the user input unit 1360 may be a keypad, dome switch, touchpad (contact-type capacitive type, pressure-type resistive type, infrared sensing type, surface ultrasonic conduction type, integral tension measurement type, piezoelectric effect type, etc.), jog wheel, jog switch, etc., but is not limited to these. Although not shown in Figure 13, the aerosol generator 1300 is further equipped with a connection interface such as a USB (universal serial bus) interface, and connects with other external devices via the USB interface to send and receive information or charge the battery 1340.

[0186] Memory 1370 is hardware that stores various data processed within the aerosol generator 1300, and stores data processed by the control unit 1310 and data being processed. Memory 1370 includes at least one type of recording medium from among flash memory type, hard disk type, multimedia card micro type, card type memory (e.g., SD or XD memory), RAM (random access memory), SRAM (static random access memory), ROM (read-only memory), EEPROM (electrically erasable programmable read-only memory), PROM (programmable read-only memory), magnetic memory, magnetic disk, and optical disk. Memory 1370 stores data such as the operating time of the aerosol generator 1300, the maximum number of puffs, the current number of puffs, at least one temperature profile, and the user's smoking pattern.

[0187] The communication unit 1380 includes at least one component for communication with other electronic devices. For example, the communication unit 1380 comprises a short-range communication unit 1382 and a wireless communication unit 1384.

[0188] The short-range communication unit 1382 includes, but is not limited to, Bluetooth® communication units, BLE (Bluetooth Low Energy) communication units, short-range wireless communication units, WLAN (Wi-Fi) communication units, Zigbee communication units, infrared (IrDA, infrared Data Association) communication units, WFD (Wi-Fi Direct) communication units, UWB (ultra wideband) communication units, Ant+ communication units, etc.

[0189] The wireless communication unit 1384 includes, but is not limited to, a cellular network communication unit, an Internet communication unit, or a computer network (e.g., LAN or WAN) communication unit. The wireless communication unit 1384 can verify and authenticate the aerosol generator 1300 within the communication network using subscriber information (e.g., International Mobile Subscriber Identifier (IMSI)).

[0190] The control unit 1310 controls the overall operation of the aerosol generator 1300. In one embodiment, the control unit 1310 comprises at least one processor. The processor may be embodied as an array of numerous logic gates, or as a combination of a general-purpose microprocessor and memory in which a program executed by the microprocessor is stored. Those skilled in the art will understand that it may also be embodied as other forms of hardware.

[0191] The control unit 1310 controls the temperature of the heater 1350 by controlling the supply of power from the battery 1340 to the heater 1350. For example, the control unit 1310 controls the power supply by controlling the switching of a switching element between the battery 1340 and the heater 1350. In another example, a direct heating circuit may control the power supply to the heater 1350 by a control command from the control unit 1310.

[0192] The control unit 1310 analyzes the results sensed by the sensing unit 1320 and controls subsequent processing. For example, based on the results sensed by the sensing unit 1320, the control unit 1310 controls the power supplied to the heater 1350 so that the heater 1350 starts or stops operating. As another example, based on the results sensed by the sensing unit 1320, the control unit 1310 controls the amount of power supplied to the heater 1350 and the duration of power supply so that the heater 1350 is heated to a predetermined temperature or maintained at an appropriate temperature.

[0193] The control unit 1310 controls the output unit 1330 based on the results sensed by the sensing unit 1320. For example, when the number of puffs counted through the puff sensor 1326 reaches a predetermined number, the control unit 1310 notifies the user that the aerosol generator 1300 will soon be finished, through at least one of the display unit 1332, the haptic unit 1334, and the acoustic output unit 1336.

[0194] One embodiment also embodies a recording medium containing computer-executable instructions, such as a program module executed by a computer. Computer-readable media are any available medium accessible by a computer, and include both volatile and non-volatile media, and isolated and non-isolated media. Computer-readable media also include both computer recording media and communication media. Computer recording media include both volatile and non-volatile, isolated and non-isolated media, embodied in any method or technique for storing information, such as computer-readable instructions, data structures, program modules, or other data. Communication media typically include computer-readable instructions, data structures, program modules, or other data such as modulated data signals or other data, and include any information transmission medium.
