Description

Technical Field

[0001] This disclosure relates to an aerosol generating apparatus. Background Technology

[0002] Recently, there has been a growing demand for alternative methods to overcome the shortcomings of traditional aerosol-generating products. For example, there is a growing need for aerosol-generating devices that generate aerosols by heating aerosol-generating substances contained in aerosol-generating products (such as cigarettes) instead of through combustion. Therefore, research on heated aerosol-generating devices is actively underway. In particular, research is actively being conducted to provide users with a consistent smoking experience in various environments. Summary of the Invention

[0003] Technical issues

[0004] When using an aerosol generating device in different environments or when using different aerosol generating articles, the temperature variation of the heater may differ, even when supplied with electricity according to the same curve. As a result, preheating time deviations occur, potentially providing users with an inconsistent smoking experience. Therefore, it is necessary to reduce preheating time deviations to provide users with a consistent smoking experience.

[0005] The technical problems to be solved by this disclosure are not limited to those described above, and other technical problems can be deduced from the following embodiments.

[0006] Technical solution

[0007] According to one or more embodiments, an aerosol generating apparatus includes a heater, a temperature sensor, and a processor. The heater is configured to heat an aerosol-generating article, the temperature sensor is configured to measure the temperature of the heater, and the processor is configured to: acquire an initial temperature of the heater as measured by the temperature sensor when receiving user input to initiate heating operation of the heater; compare the initial temperature of the heater with a first temperature; control the heater to perform heating operation according to a preset temperature curve based on the initial temperature being lower than the first temperature; and control the heater to stop heating operation for a first delay time when the temperature of the heater reaches a second temperature higher than the first temperature.

[0008] Beneficial effects

[0009] Aerosol generating devices can minimize variations in preheating time across different environments by performing heating operations based on the initial temperature of the heater, thus providing users with a consistent smoking experience.

For example, the expression “at least one of a, b, and c” should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0026] In the following description, the present disclosure will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the present disclosure are shown to enable those skilled in the art to readily implement the present disclosure. However, the present disclosure may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein.

[0027] In the following, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0028] Figures 1 to 3 This is a view showing an example of an aerosol-generating article being inserted into an aerosol-generating apparatus.

[0029] Reference Figure 1 The aerosol generating device 100 may include a battery 110, a processor 120, and a heater 130.

[0030] Reference Figure 2 and Figure 3 The aerosol generating apparatus 100 may also include a vaporizer 140. Furthermore, the aerosol generating article 200 may be inserted into the internal space of the aerosol generating apparatus 100.

[0031] Figures 1 to 3Components of the aerosol generating apparatus 100 relevant to this embodiment are shown. Therefore, those skilled in the art who are familiar with this embodiment will understand that, in addition to… Figures 1 to 3 In addition to the components shown, the aerosol generating apparatus 100 may also include other general-purpose components.

[0032] also, Figure 2 and Figure 3 The aerosol generating apparatus 100 shown includes a heater 130. However, the heater 130 may be omitted if necessary.

[0033] Figure 1 A battery 110, processor 120, and heater 130 arranged in series are shown. Additionally, Figure 2 A battery 110, processor 120, carburetor 140, and heater 130 arranged in series are shown. Additionally, Figure 3 The vaporizer 140 and heater 130 are shown arranged in parallel. However, the internal structure of the aerosol generating device 100 is not limited to... Figures 1 to 3 The structure shown. In other words, depending on the design of the aerosol generating device 100, the battery 110, processor 120, heater 130, and vaporizer 140 can be arranged in different ways.

[0034] When the aerosol generating article 200 is inserted into the aerosol generating apparatus 100, the aerosol generating apparatus 100 can operate the heater 130 and / or the vaporizer 140 to generate aerosols from the aerosol generating article 200 and / or the vaporizer 140. The aerosols generated by the heater 130 and / or the vaporizer 140 are delivered to the user by passing through the aerosol generating article 200.

[0035] If necessary, the aerosol generating device 100 can heat the heater 130 even if the aerosol generating article 200 is not inserted into the aerosol generating device 100.

[0036] Battery 110 can supply the power required to operate the aerosol generating device 100. For example, battery 110 can supply power to heat heater 130 or vaporizer 140, and can supply power to operate processor 120. In addition, battery 110 can supply power to operate displays, sensors, motors, etc. installed in aerosol generating device 100.

[0037] The processor 120 typically controls the operation of the aerosol generating device 100. Specifically, the processor 120 can control not only the operation of the battery 110, heater 130, and vaporizer 140, but also the operation of other components included in the aerosol generating device 100. Furthermore, the processor 120 can check the status of each component of the aerosol generating device 100 to determine whether the aerosol generating device 100 is capable of operation.

[0038] The processor 120 may be implemented as an array of logic gates, or as a combination of a general-purpose microprocessor and a memory storing a program that can be executed in the microprocessor. Those skilled in the art will understand that the processor may be implemented in other forms of hardware.

[0039] The heater 130 can be heated by electricity supplied by the battery 110. For example, when the aerosol generating article 200 is inserted into the aerosol generating apparatus 100, the heater 130 can be located outside the aerosol generating article 200. Therefore, the heated heater 130 can raise the temperature of the aerosol generating substance in the aerosol generating article 200.

[0040] Heater 130 may include a resistance heater. For example, heater 130 may include an electrically conductive trace, and heater 130 may be heated when current flows through the electrically conductive trace. However, heater 130 is not limited to the above examples and may include all heaters that can be heated to a desired temperature. Here, the desired temperature may be preset in the aerosol generating apparatus 100, or it may be set to a temperature desired by the user.

[0041] As another example, heater 130 may include an induction heater. Specifically, heater 130 may include an electrically conductive coil for heating the aerosol-generating article by an induction heating method, and the aerosol-generating article may include a base that can be heated by the induction heater.

[0042] For example, heater 130 may include tubular heating elements, plate heating elements, needle heating elements or rod heating elements, and may heat the interior or exterior of aerosol generating article 200 depending on the shape of the heating element.

[0043] Furthermore, the aerosol generating apparatus 100 may include a plurality of heaters 130. Here, the plurality of heaters 130 may be inserted into the aerosol generating article 200 or may be arranged outside the aerosol generating article 200. Additionally, some of the plurality of heaters 130 may be inserted into the aerosol generating article 200, while others may be arranged outside the aerosol generating article 200. Furthermore, the shape of the heaters 130 is not limited to... Figures 1 to 3The shape shown can be, and can include various shapes.

[0044] The vaporizer 140 can generate an aerosol by heating the liquid composition, and the generated aerosol can be delivered to the user through the aerosol generating article 200. In other words, the aerosol generated by the vaporizer 140 can move along the airflow channel of the aerosol generating device 100, and the airflow channel can be configured such that the aerosol generated by the vaporizer 140 can be delivered to the user through the aerosol generating article 200.

[0045] For example, vaporizer 140 may include, but is not limited to, a liquid reservoir, a liquid delivery element, and a heating element. For example, the liquid reservoir, the liquid delivery element, and the heating element may be included as separate modules in aerosol generating apparatus 100.

[0046] The liquid reservoir can store a liquid composition. For example, the liquid composition may be a liquid containing tobacco-containing materials having volatile tobacco flavor components, or a liquid containing non-tobacco materials. The liquid reservoir may be detachable from the vaporizer 140, or it may be integrally formed with the vaporizer 140.

[0047] For example, the liquid composition may include water, solvent, ethanol, plant extracts, fragrance, flavoring agents, or vitamin mixtures. Fragrances may include, but are not limited to, menthol, peppermint, spearmint oil, and various fruit flavoring ingredients. Flavoring agents may include ingredients capable of providing the user with a variety of fragrances or flavors. Vitamin mixtures may be, but are not limited to, a mixture of at least one of vitamins A, B, C, and E. Furthermore, the liquid composition may contain aerosol-forming substances such as glycerin and propylene glycol.

[0048] A liquid delivery element can deliver a liquid composition from a liquid reservoir to a heating element. For example, the liquid delivery element can be a core, such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic, but is not limited thereto.

[0049] A heating element is a component used to heat a liquid composition conveyed by a liquid conveying element. For example, a heating element can be a metal heating wire, a metal hot plate, a ceramic heater, etc., but is not limited to these. Furthermore, the heating element may include a conductive wire, such as a nichrome alloy wire, and the heating element may be positioned to wrap around the liquid conveying element. The heating element can be heated by an electric current supply and can transfer heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, an aerosol can be generated.

[0050] For example, the vaporizer 140 may be referred to as a cartomizer or atomizer, but is not limited to these terms.

[0051] In addition to the battery 110, processor 120, heater 130, and vaporizer 140, the aerosol generating apparatus 100 may also include common components. For example, the aerosol generating apparatus 100 may include a display capable of outputting visual information and / or a motor for outputting tactile information. Furthermore, the aerosol generating apparatus 100 may include at least one sensor (suction sensor, temperature sensor, aerosol generating article insertion detection sensor, etc.). Moreover, the aerosol generating apparatus 100 may be configured to allow the introduction of external air or the exhaust of internal air even when the aerosol generating article 200 is inserted into the aerosol generating apparatus 100.

[0052] Despite Figures 1 to 3 Not shown, but the aerosol generating device 100 and the additional bracket can form a system together. For example, the bracket can be used to charge the battery 110 of the aerosol generating device 100. Alternatively, the heater 130 can be heated when the bracket and the aerosol generating device 100 are connected to each other.

[0053] The aerosol generating article 200 can be similar to a conventional combustible cigarette. For example, the aerosol generating article 200 can be divided into a first part including aerosol generating material and a second part including a filter, etc. Alternatively, the second part of the aerosol generating article 200 can also include aerosol generating material. For example, aerosol generating material in the form of granules or capsules can be inserted into the second part.

[0054] The entire first part can be inserted into the aerosol generating device 100, while the second part can be exposed to the outside. Alternatively, only a portion of the first part can be inserted into the aerosol generating device 100, or the entire first part and a portion of the second part can be inserted into the aerosol generating device 100. The user can inhale the aerosol while the second part is held in the user's mouth. In this case, the aerosol is generated by outside air passing through the first part, and the generated aerosol passes through the second part and is delivered to the user's mouth.

[0055] For example, outside air can flow into at least one air passage formed in the aerosol generating device 100. For example, the opening and closing and / or size of the air passage formed in the aerosol generating device 100 can be adjusted by the user. Therefore, the user can adjust the amount of smoke and the smoking experience. As another example, outside air can flow into the aerosol generating article 200 through at least one hole formed in the surface of the aerosol generating article 200.

[0056] Figure 4 This is a view showing an example of an aerosol generating apparatus employing an induction heating method.

[0057] Reference Figure 4 The aerosol generating apparatus 100 may include a battery 110, a processor 120, a coil 410, and a base 420. Furthermore, at least a portion of the aerosol generating article 200 may be housed in the cavity 430 of the aerosol generating apparatus 100. Figure 4 The aerosol generating product 200, battery 110, and processor 120 can respectively correspond to Figures 1 to 3 The aerosol generating product 200, battery 110, and processor 120. Additionally, Figure 4 The coil 410 and the base 420 can be included Figures 1 to 3 In heater 130. Therefore, repeated descriptions of it are omitted.

[0058] Figure 4 An aerosol generating apparatus 100 including components relevant to this embodiment is shown. Therefore, those skilled in the art will understand that the aerosol generating apparatus 100 may further include… Figure 4 Other general-purpose components besides those shown.

[0059] Coil 410 can be wound around cavity 430. Figure 4 The coil 410 is shown surrounding the cavity 430, but this disclosure is not limited thereto.

[0060] When the aerosol generating article 200 is placed in the cavity 430 of the aerosol generating apparatus 100, the aerosol generating apparatus 100 can supply power to the coil 410, causing the coil 410 to generate a variable magnetic field. When the magnetic field generated by the coil 410 passes through the base 420, the base 420 can be heated.

[0061] For example, when the magnetic field strength in the base 420 changes, an electric field is generated in the base 420, thereby causing eddy currents to flow in the base 420. The eddy currents generate heat proportional to the current density and conductor resistance in the base 420.

[0062] The base 420 is heated by an eddy current, and the aerosol generating material in the aerosol generating article 200 is heated by the heated base 420, thus generating an aerosol. The aerosol generated by the aerosol generating material passes through the aerosol generating article 200 and is delivered to the user.

[0063] Battery 110 can supply power to coil 410 to generate a magnetic field. Processor 120 can be electrically connected to coil 410.

[0064] The coil 410 may be a conductive coil that generates a variable magnetic field by using power supplied from the battery 110. The coil 410 may surround at least a portion of the cavity 430. The variable magnetic field generated by the coil 410 may be applied to a base 420 disposed at the inner end portion of the cavity 430.

[0065] When the variable magnetic field generated from coil 410 passes through base 420, base 420 is heated, and base 420 may comprise metal or carbon. For example, base 420 may comprise at least one of ferrite, ferromagnetic alloy, stainless steel, and aluminum.

[0066] Furthermore, the base 420 may include at least one of the following: ceramics, such as graphite, molybdenum, silicon carbide, niobium, nickel alloys, metal films, or zirconium oxide; transition metals, such as nickel (Ni) or cobalt (Co); and metalloids, such as boron (B) or phosphorus (P). However, the base 420 is not limited to the examples described above and may be made of any material, as long as the material can be heated to a desired temperature when a variable magnetic field is applied to it. Here, the desired temperature may be preset in the aerosol generating device 100 or set to a temperature desired by the user.

[0067] When the aerosol generating article 200 is housed in the cavity 430 of the aerosol generating apparatus 100, the base 420 may surround at least a portion of the aerosol generating article 200. Therefore, the heated base 420 can raise the temperature of the aerosol generating substance in the aerosol generating article 200.

[0068] Figure 4 The illustration shows at least a portion of the aerosol-generating article surrounded by a base 420, but this disclosure is not limited thereto. For example, the base 420 may include tubular heating elements, plate heating elements, needle heating elements, or rod heating elements, and may heat the interior or exterior of the aerosol-generating article 200 depending on the shape of the heating elements.

[0069] Furthermore, the aerosol generating apparatus 100 may include a plurality of bases 420. In this case, the plurality of bases 420 may be arranged outside the aerosol generating article 200, or the plurality of bases 420 may be arranged to be inserted into the aerosol generating article. Additionally, some of the plurality of bases 420 may be inserted into the aerosol generating article 200, while others may be arranged outside the aerosol generating article 200. Furthermore, the shape of the bases 420 is not limited to... Figure 4 The shape shown can be transformed into various shapes.

[0070] In the following text, reference will be made to Figure 5 and Figure 6 An example of aerosol-generated article 200 is described.

[0071] Figure 5 and Figure 6 An example of an aerosol-generated article is shown.

[0072] Reference Figure 5 The aerosol-generating article 200 may include a tobacco stick 210 and a filter stick 220. (See above for reference.) Figures 1 to 3 The first part of the description may include a tobacco stick 210, and the second part may include a filter stick 220.

[0073] Figure 5 The filter rod 220 is shown to include a single segment. However, the filter rod 220 is not limited to this. In other words, the filter rod 220 may include multiple segments. For example, the filter rod 220 may include a first segment configured to cool the aerosol and a second segment configured to filter specific components contained in the aerosol. Furthermore, the filter rod 220 may also include at least one segment configured to perform other functions, as needed.

[0074] At least one package 240 can be used to package the aerosol generating article 200. The package 240 may have at least one opening through which external air can be introduced or internal air can be exhausted. For example, the aerosol generating article 200 may be packaged by one package 240. As another example, the aerosol generating article 200 may be double-packaged by two or more packages 240. For example, the tobacco stick 210 may be packaged by a first package 241, and the filter stick 220 may be packaged by packages 242, 243, and 244. Furthermore, the entire aerosol generating article 200 may be repackaged by a single additional package 245. When the filter stick 220 comprises multiple segments, each segment may be packaged by packages 242, 243, and 244.

[0075] The tobacco stick 210 may include aerosol-generating substances. For example, the aerosol-generating substances may include, but are not limited to, at least one of glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. Furthermore, the tobacco stick 210 may include other additives, such as flavoring agents, humectants, and / or organic acids. Additionally, the tobacco stick 210 may include flavored liquids, such as menthol or humectants, injected into the tobacco stick 210.

[0076] The tobacco stick 210 can be manufactured in various forms. For example, the tobacco stick 210 can be formed as a sheet or shreds. Furthermore, the tobacco stick 210 can be formed as a tubular cigarette made from tiny fragments cut from a tobacco sheet. Additionally, the tobacco stick 210 can be surrounded by a heat-conducting material. For example, the heat-conducting material can be, but is not limited to, a metal foil such as aluminum foil. For example, the heat-conducting material surrounding the tobacco stick 210 can make the heat transferred to the tobacco stick 210 evenly distributed, thus increasing the thermal conductivity applied to the tobacco stick and improving the flavor of the tobacco. Furthermore, the heat-conducting material surrounding the tobacco stick 210 can serve as a base for heating by an induction heater. Here, although not shown in the figures, in addition to the heat-conducting material surrounding the tobacco stick 210, the tobacco stick 210 may also include an additional base.

[0077] The filter rod 220 may include a cellulose acetate filter. The shape of the filter rod 220 is not limited. For example, the filter rod 220 may include a cylindrical or tubular rod with a hollow interior. Furthermore, the filter rod 220 may include a concave rod. When the filter rod 220 comprises multiple segments, at least one of the segments may have a different shape.

[0078] The filter rod 220 can be configured to produce fragrance. For example, a fragrance liquid can be injected into the filter rod 220, or additional fibers coated with fragrance liquid can be inserted into the filter rod 220.

[0079] Furthermore, the filter rod 220 may include at least one capsule 230. Here, the capsule 230 may generate a fragrance or aerosol. For example, the capsule 230 may have a configuration in which a liquid containing a fragrance material is encapsulated by a membrane. For example, the capsule 230 may have a spherical shape or a cylindrical shape, but is not limited thereto.

[0080] When the filter rod 220 includes a section configured to cool the aerosol, the cooling section may comprise a polymeric material or a biodegradable polymeric material. For example, the cooling section may comprise only pure polylactic acid, but the material used to form the cooling section is not limited thereto. In some embodiments, the cooling section may comprise a cellulose acetate filter having multiple pores. However, the cooling section is not limited to the examples described above and is not restricted as long as the cooling section cools the aerosol.

[0081] Reference Figure 6 The aerosol generating article 300 may further include a front plug 330. The front plug 330 may be located on the side of the tobacco stick 310 opposite to the filter rod 320. During smoking, the front plug 330 prevents the tobacco stick 310 from separating outwards and prevents liquefied aerosol from flowing from the tobacco stick 310 into the aerosol generating device. Figures 1 to 3 (of 100)

[0082] The filter rod 320 may include a first segment 321 and a second segment 322. Here, the first segment 321 may correspond to... Figure 5 The first segment of the filter rod 220, and the second segment 322 can correspond to Figure 5 The second section of the filter rod 220.

[0083] The diameter and total length of the aerosol-generated article 300 can correspond to Figure 5 The diameter and total length of the aerosol-generating article 200. For example, the length of the front plug 330 is about 7 mm, the length of the tobacco stick 310 is about 15 mm, the length of the first segment 321 is about 12 mm, and the length of the second segment 322 is about 14 mm, but not limited thereto.

[0084] At least one package 350 can be used to package the aerosol-generating article 300. Package 350 may have at least one opening through which external air can be introduced or internal air can be expelled. For example, the tip plug 330 may be packaged in a first package 351, the tobacco stick 310 in a second package 352, the first segment 321 in a third package 353, and the second segment 322 in a fourth package 354. Furthermore, the entire aerosol-generating article 300 may be repackaged in a fifth package 355.

[0085] Furthermore, at least one perforation 360 may be formed in the fifth package 355. For example, the perforation 360 may be formed in the area surrounding the tobacco stick 310, but is not limited thereto. The perforation 360 can be used to... Figure 2 and Figure 3 The heat generated by the heater 130 shown is transferred to the interior of the tobacco stick 310.

[0086] Furthermore, the second segment 322 may include at least one capsule 340. Here, the capsule 340 may generate a fragrance or aerosol. For example, the capsule 340 may have a configuration in which a liquid containing a fragrance material is encapsulated by a membrane. For example, the capsule 340 may have a spherical shape or a cylindrical shape, but is not limited thereto.

[0087] Figure 7 This is a block diagram showing the configuration of an aerosol generating apparatus according to an embodiment.

[0088] Reference Figure 7 The aerosol generating device 100 may include a heater 130, a temperature sensor 710, and a processor 120. Figure 7 The heater 130 can correspond to Figures 1 to 4 The heater 130, coil 410, and base 420, and Figure 7 The processor 120 can correspond to Figures 1 to 4The processor is 120. Therefore, redundant descriptions have been omitted.

[0089] Figure 7 An aerosol generating apparatus 100 including components relevant to this embodiment is shown. Therefore, those skilled in the art will understand that the aerosol generating apparatus 100 may further include… Figure 7 Other general-purpose components besides those shown.

[0090] Heater 130 can heat the aerosol generating article. For example, heater 130 can heat the aerosol generating article disposed in aerosol generating apparatus 100, thereby heating the aerosol generating substance contained in the aerosol generating article.

[0091] Temperature sensor 710 can be arranged adjacent to heater 130 to directly or indirectly measure the temperature of heater 130. For example, temperature sensor 710 can detect the temperature of heater 130 and output a voltage corresponding to the detected temperature. Alternatively, temperature sensor 710 may include a thermistor for outputting a resistance value corresponding to the detected temperature. Processor 120 can determine the temperature of heater 130 based on information received from temperature sensor 710 (e.g., voltage or resistance value). However, the above-described method of operating temperature sensor 710 is merely an example, and any method can be applied to temperature sensor 710 as long as it is a method of sensing or measuring temperature.

[0092] The processor 120 can respond to user input. User input is an input initiating a heating operation of the aerosol generating apparatus 100 by the user, and the input method can be varied. For example, the input method may include pressing a button, touching a touchscreen, inserting an aerosol generating article, etc. The input method based on the insertion of an aerosol generating article will be described later. However, this is only an example, and the user input method can include any method that the aerosol generating apparatus 100 can respond to. In response to user input, the processor 120 can execute a process for heating operation of the aerosol generating apparatus 100.

[0093] The processor 120 can change the heating operation process based on the initial temperature of the heater 130, which is the temperature at which the user input is received. For example, when the initial temperature of the heater 130 is close to room temperature, the processor 120 can immediately perform the heating operation, while when the initial temperature of the heater 130 is the temperature of a state that has already been heated, the processor 120 can perform the heating operation after a certain period of time.

[0094] In response to user input, processor 120 can determine the process for performing the heating operation. Processor 120 can compare the initial temperature of heater 130, measured by temperature sensor 710, with a first temperature to determine the process. The first temperature can be set to a suitable value to determine whether the initial temperature of heater 130 is close to room temperature or a temperature under heating conditions. For example, the first temperature can be about 50°C to about 80°C.

[0095] When the initial temperature of heater 130 is lower than a first temperature, processor 120 can use heater 130 to perform a heating operation. For example, processor 120 can perform a heating operation using heater 130 according to a preset temperature curve. When the second temperature is reached as heater 130 is heated, processor 120 can stop the heating operation for a first delay time. Processor 120 can restart the heating operation after the first delay time has elapsed. (Refer to...) Figure 9 The operation method of the aerosol generating device 100 when the initial temperature of the heater 130 is lower than the first temperature is described in detail.

[0096] When the initial temperature of heater 130 is higher than or equal to the first temperature, processor 120 may not immediately perform a heating operation using heater 130, but may perform the heating operation after a second delay time. Processor 120 may determine the second delay time based on the initial temperature of heater 130. (Refer to...) Figure 11 The operation method of the aerosol generating device 100 when the initial temperature of the heater 130 is higher than or equal to the first temperature is described in detail.

[0097] The aerosol generating apparatus 100 may further include a cavity (not shown) for accommodating the aerosol generating article. The cavity may form a accommodating space for accommodating the aerosol generating article in the aerosol generating apparatus 100. Figure 7 The cavity can correspond to Figure 4 Cavity 430. Therefore, redundant descriptions of it are omitted.

[0098] In one embodiment, the aerosol generating apparatus 100 may further include an insertion detection sensor (not shown). The insertion detection sensor can detect whether the aerosol generating article is inserted into the cavity. For example, the aerosol generating article may include a metallic material such as aluminum, and the insertion detection sensor may include a sensing sensor for sensing changes in the magnetic field that occur when the aerosol generating article is inserted into the cavity. However, this disclosure is not limited thereto, and the insertion detection sensor may include an optical sensor, a temperature sensor, a resistance sensor, etc.

[0099] In this scenario, the insertion of the aerosol-generating article into the cavity, detected by the insertion detection sensor, can serve as user input for the heating operation. That is, when the insertion of the aerosol-generating article is detected, the processor 120 can automatically execute the heating operation without additional external input.

[0100] In another embodiment, the aerosol generating apparatus 100 may further include an identification sensor (not shown) that identifies the type of aerosol generating article in the insertion cavity based on an identification mark provided by the aerosol generating article. For example, the identification mark indicating the type of aerosol generating article may be printed on or attached to packaging of the aerosol generating article or included in the aerosol generating article as a metal material. Therefore, identification marks provided on aerosol generating articles of the same type may be identical, and identification marks provided on aerosol generating articles of different types may be different. For example, the identification mark may include, but is not limited to, a mark representing a specific color, a specific phrase, a barcode, a quick response (QR) code, or a specific metal material.

[0101] The identification sensor can identify identification marks affixed to the aerosol-generating article contained in the aerosol generating apparatus 100. The identification sensor can identify the identification mark by detecting its color, pattern, shape, or material. Depending on the type of identification mark, the identification sensor can include a suitable configuration. For example, depending on the type of identification mark, the identification sensor can include an inductive sensor, a color sensor, an optical scanner, a near-field communication (NFC) reader, a radio frequency identification (RFID) reader, etc. The above examples are for illustrative purposes only and are not intended to limit the type of identification sensor. The identification sensor is not limited, as long as it can identify the identification mark.

[0102] When the identification sensor includes an inductive sensor, the identification mark can be made of metallic material. The identification sensor can identify the type of aerosol-generating article based on the amount of inductance change detected when the aerosol-generating article is inserted. In this case, the identification sensor can also be used as an insertion detection sensor.

[0103] Processor 120 can determine the first delay time based on the type of aerosol-generated article identified by the identification sensor. (See reference...) Figure 9 This describes in detail a method for determining the first delay time based on the type of aerosol-generated article.

[0104] In another embodiment, heater 130 may include a coil (not shown) and a base (not shown). The coil may surround a cavity and generate a variable magnetic field. The base may be disposed inside the coil and may be heated by the variable magnetic field. Figure 7 The coil and base can correspond to Figure 4The coil 410 and the base 420. Therefore, redundant descriptions of them are omitted.

[0105] The processor 120 can perform or stop the heating operation by controlling the power supplied to the coil. For example, the processor 120 can perform the heating operation by controlling the battery of the aerosol generating device 100 to supply power to the coil, and the processor 120 can stop the heating operation by controlling the battery to stop supplying power to the coil. Furthermore, the processor 120 can restart the heating operation by controlling the battery of the aerosol generating device 100 to supply power to the coil again after a first delay time following the cessation of the heating operation. (Referring below...) Figure 9 Describe the operation of the coil and base during the first delay time.

[0106] Figure 8 It is a graph showing the deviation in time from the target temperature when the initial temperature of the heater is lower than the first temperature.

[0107] Reference Figure 8 Figure 810 and Figure 820 are shown. Figure 810 and Figure 820 illustrate the results of performing heating operations on the aerosol generating apparatus in different environments. For example, different environments can refer to situations where the external temperature or humidity of the aerosol generating apparatus differs, or where different types of aerosol generating articles are used. Alternatively, different environments can refer to using different types of cigarettes, even if these different types of cigarettes belong to the same type of aerosol generating article. The target temperature is the temperature at which preheating is complete, therefore the time t1 or t2 to reach the target temperature can correspond to the time at which preheating is complete.

[0108] Depending on the type of aerosol-generated article, the thickness and material composition of the packaging may vary. Furthermore, even among the same type of aerosol-generated articles, deviations in packaging thickness and material composition may occur between individual articles during the manufacturing process. Therefore, even when power is supplied to the heater according to the same curve, the time to reach the target temperature may differ depending on the type of aerosol-generated article or the unique characteristics between articles of the same type. Figure 8 As shown, there is a difference Δt between the target temperature reaching time t1 according to the first curve 810 and the target temperature reaching time t2 according to the second curve 820. For example, in the second curve 820, the aerosol-generating article may have a thicker package than the aerosol-generating article in the first curve 810.

[0109] The processor can use proportional-integral-derivative (PID) control to perform the heating operation. PID control can be implemented to reduce both the time it takes to reach the target temperature and overshoot. Therefore, the heater temperature initially rises rapidly to reach the target temperature, but then rises slowly as it approaches the target temperature to reduce overshoot. Thus, as... Figure 8 As shown, as the heater temperature approaches the target temperature, the time difference between the first curve 810 and the second curve 820 becomes larger.

[0110] Therefore, when preheating time varies depending on changes in the aerosol-generating product or the external environment, it may not provide users with a consistent smoking experience. However, Figure 7 The aerosol generating apparatus 100 can provide a more consistent preheating time (i.e., the time to reach the target temperature) by applying a first delay time and a second delay time to the heating operation using the heater, regardless of differences in the aerosol generating article being used or the external environment.

[0111] Figure 9 It is a graph showing the operation method of the aerosol generating apparatus according to the embodiment when the initial temperature of the heater is lower than the first temperature.

[0112] Reference Figure 9 The first graph 910 and the second graph 920 are shown. Figure 9 The first curve 910 shows the relationship with Figure 8 The first curve (810) shows the results of heating operations performed in the same environment, and Figure 9 The second curve, Graph 920, shows the relationship with... Figure 8 The second curve, Graph 820, shows the results of heating operations performed in the same environment. For example, Figure 9 The first curve 910 and Figure 8 The first graph 810 can show the results of the heating operation performed on the same aerosol-generating article.

[0113] like Figure 9 As shown, if the initial temperature of the heater is measured to be lower than the first temperature, the processor can immediately perform a heating operation using the heater. When the second temperature is reached as the heater is heated, the processor can stop the heating operation after a first delay time t. d .

[0114] The second temperature can be set to a suitable value taking into account at least one of the heater's performance, the power supplied to the heater, the target temperature of the heater, and the time it takes for the heater to reach the target temperature. For example, the second temperature can be from about 100°C to about 130°C.

[0115] First delay time td This is the time between when the heating operation stops and when it restarts. The difference Δt between the times t1 and t2 when the target temperature is reached can be determined based on the first delay time t. d The length varies. The first delay time t d It can be set to a suitable time so that the difference Δt between the time t1 and t2 for the target temperature to be reached decreases and the time t1 and t2 for the target temperature to be reached do not increase significantly.

[0116] The first delay time can be a preset time during the design process of manufacturing the aerosol generating device. Furthermore, the first delay time can be determined by a processor. For example, the first delay time can be determined based on at least one of the heater's performance, the power supplied to the heater, the target temperature of the heater, and the time it takes for the heater to reach the target temperature. For example, the first delay time can be set to approximately 2 seconds to approximately 5 seconds.

[0117] Even if the same first delay time is applied to the second curve 920 at the second temperature, the difference Δt between the time to reach the target temperature and the time to reach the target temperature will differ due to at least one of the following reasons. Figure 8 The difference Δt can still be reduced compared to the previous value.

[0118] Packaging and composition materials can vary between different types of aerosol-generating articles or between unique articles of the same type. Since the packaging and materials of the aerosol-generating articles soften during the first delay time after the heater has heated to the second temperature, the differences between aerosol-generating articles can be reduced. The processor can reduce the difference Δt between the time it takes to reach the target temperature by restarting the heating operation in a state where the differences between aerosol-generating articles have been reduced.

[0119] Alternatively, when the heating operation restarts after the first delay time, according to PID control, the heating operation can be restarted by executing the same processing as when the first heating operation began. Therefore, when the heating operation restarts, the heater temperature will rise rapidly, similar to the case when heating is performed at the initial temperature. In this case, because the difference between the second temperature and the target temperature is smaller than the difference between the initial temperature and the target temperature, the heating rate (i.e., the rate of temperature rise) will be higher than if the first delay time were not applied. Figure 8 The temperature curve in graph 820 begins to decrease at higher temperatures. Therefore, the time period of lower heating rate becomes shorter, and the difference Δt between the time to reach the target temperature decreases.

[0120] like Figure 9As shown, even during the first delay period after the heating operation stops (i.e., when power from the battery to the heater is cut off), the heater temperature may still rise, albeit at a slower rate than during the heating operation. Specifically, the heater can continue heating using any remaining power supplied to it but not consumed until the heating operation stops. Because the heater temperature rises slowly even after the heating operation stops, the time to reach the target temperature can be reduced compared to when the heater temperature is maintained or decreased.

[0121] The heater includes a coil and a base (see...) Figure 4 In this embodiment, the base can continue to conduct heat to the aerosol-generated article during a first delay time after the heating operation stops, via residual eddy currents induced from the variable magnetic field. Even if power is stopped to the coil, a portion of the eddy currents generated in the base may be retained, thus allowing heating of the base to continue.

[0122] Furthermore, the coil can still generate a variable magnetic field using the supplied and remaining power. Due to the remaining power, the base can continue to conduct heat to the aerosol-generated article through the variable magnetic field generated by the coil. Because the coil surrounds a large portion of the base and is wound multiple times, the variable magnetic field generated by the remaining power can effectively maintain heating of the base even after the heating operation has stopped. Therefore, when the heater includes both a coil and a base, heating of the base can be effectively maintained during the first delay period after the heating operation stops, thereby reducing the time to reach the target temperature.

[0123] The processor can determine the first delay time using various methods described below. For example, the processor can determine the first delay time based on the time it takes for the heater to reach the second temperature from the start of the heating operation. The first delay time can be negatively correlated with the time it takes for the heater to reach the second temperature. In other words, as the time it takes for the heater to reach the second temperature becomes longer, the first delay time can be reduced, minimizing the difference between the times the target temperature is reached.

[0124] Alternatively, the processor can determine the first delay time based on the initial temperature of the heater. In this case, the first delay time can be positively correlated with the initial temperature of the heater. In other words, as the initial temperature of the heater increases, the first delay time can be increased to minimize the difference between the time it takes for the target temperature to be reached.

[0125] Alternatively, the processor can determine the first delay time based on the type of aerosol-generating article identified by the identification sensor. The memory of the aerosol-generating device can store the first delay time corresponding to each type of aerosol-generating article. The first delay time stored in the memory can be predetermined such that various types of aerosol-generating articles have substantially the same target temperature reaching time. For example, for aerosol-generating article types that heat relatively quickly, the first delay time can be set relatively long. The processor can determine the first delay time corresponding to the identified aerosol-generating article type from the various first delay times stored in the memory.

[0126] Figure 10 It is a graph showing the deviation in time from the target temperature when the initial temperature of the heater is higher than or equal to the first temperature.

[0127] Reference Figure 10 The diagram illustrates a first graph 1010 and a second graph 1020. First graph 1010 and second graph 1020 show the results of a heating operation that begins after a previous heating operation and before the heater's high temperature drops to room temperature. First graph 1010 and second graph 1020 show the results of heating operations performed by the aerosol generating device in different environments. For example, first graph 1010 may have a higher initial temperature than second graph 1020 because the heating operation begins a shorter time after the previous heating operation has ended.

[0128] Even when power is supplied to the heater according to the same curve, the time to reach the target temperature may differ depending on the initial temperature of the heater. For example... Figure 10 As shown, the target temperature reaching time t1 of the first curve 1010, which has a higher initial temperature, can be earlier than the target temperature reaching time t2 according to the second curve 1020. Therefore, due to the difference in initial temperature, a difference Δt can occur in the target temperature reaching time.

[0129] If the preheating time deviates whenever the initial temperature of the heater changes, it may not provide users with a consistent smoking experience. Figure 7 The aerosol generating device 100 can provide a more consistent preheating time (or target temperature attainment time) regardless of the initial temperature of the heater by applying a second delay time to the heating operation using the heater.

[0130] Figure 11 It is a graph showing the operation method of the aerosol generating apparatus according to the embodiment when the initial temperature of the heater is higher than or equal to the first temperature.

[0131] Reference Figure 11The first curve 1110 and the second curve 1120 are shown. Figure 11 The first curve 1110 shows the relationship with Figure 10 The first curve (1010) shows the results of heating operations performed in the same environment, and Figure 11 The second curve, Figure 1120, shows the relationship between... Figure 10 The second curve, Graph 1020, shows the results of heating operations performed in the same environment. For example, Figure 11 The first curve 1110 can be shown in relation to Figure 10 The first curve 1010 shows the result of the heating operation performed at the same initial temperature.

[0132] like Figure 11 As shown, when the initial temperature of the heater is measured to be greater than or equal to the first temperature, the processor can initiate a second delay time t. d1 or t d2 Heating is then performed. If the initial temperature of the heater is higher than or equal to the first temperature, the processor may begin the heating operation after a second delay time has elapsed since the initial temperature of the heater was measured or since receiving user input for the heating operation (e.g., when insertion of an aerosol-generating article is detected). The difference between the target temperature arrival time and the target temperature arrival time can vary depending on the length of the second delay time. The second delay time can be set to a suitable duration such that the difference between the target temperature arrival times is reduced and the target temperature arrival time does not increase significantly.

[0133] The processor can determine the second delay time based on the initial temperature of the heater. The second delay time can be positively correlated with the initial temperature of the heater. In other words, as the initial temperature of the heater increases, the second delay time can be increased to minimize the difference between the time it takes for the target temperature to be reached.

[0134] like Figure 11 As shown, the second delay time t of the first curve 1110 with a lower initial temperature d1 The second delay time t can be compared to the second curve 1120. d2 Shorter. Because the heating operation for the first curve 1110, which shows a lower initial temperature, begins earlier than the heating operation for the second curve 1120, therefore compared to... Figure 10 The difference between the time it takes for the target temperature to be reached can be reduced.

[0135] Figure 12 This is a flowchart illustrating the operation method of the aerosol generating apparatus according to an embodiment.

[0136] Reference Figure 12The operation method of the aerosol generating apparatus according to the embodiment includes... Figure 7 The operation is handled in the aerosol generating apparatus 100 shown. Therefore, it can be seen from the above regarding... Figure 7 The description of the aerosol generating device 100 shown can also be applied to Figure 12 The operating method of the aerosol generating device is the same, even if it is omitted below.

[0137] In operation 1210, the aerosol generating device can determine whether user input has been received. If no user input is received, the aerosol generating device can wait until user input is received. For example, the aerosol generating device can repeatedly perform operation 1210 according to a preset cycle. When user input is received, the aerosol generating device can perform operation 1220. User input may include pressing a button, touching a touchscreen, detecting the insertion of the aerosol-generated article, etc.

[0138] In operation 1220, the aerosol generating device can measure the initial temperature of the heater using a temperature sensor; this initial temperature is the temperature at which the user input is received. Furthermore, the aerosol generating device can compare the initial temperature of the heater with a first temperature.

[0139] In operation 1230, the aerosol generating apparatus can determine whether the initial temperature of the heater is lower than a first temperature. The aerosol generating apparatus can perform operation 1240 when the initial temperature of the heater is lower than the first temperature, and the aerosol generating apparatus can perform operation 1280 when the initial temperature of the heater is higher than or equal to the first temperature.

[0140] In operation 1240, the aerosol generating apparatus can use a heater to perform a heating operation. When the initial temperature of the heater is measured to be below a first temperature, the aerosol generating apparatus can immediately use the heater to perform the heating operation.

[0141] In operation 1250, the aerosol generating device can determine whether the heater temperature has reached the second temperature. The aerosol generating device can measure the temperature of the heated heater in real time using a temperature sensor. When the heater temperature reaches the second temperature, the aerosol generating device can perform operation 1260.

[0142] In operation 1260, the aerosol generating device may stop the heating operation for a preset first delay time. For example, the first delay time may be a preset time that takes into account at least one of the heater's performance, the power supplied to the heater, the target temperature of the heater, and the time it takes for the heater to reach the target temperature.

[0143] In operation 1270, after a first delay time has elapsed since the heating operation was stopped in operation 1260, the aerosol generating apparatus can restart the heating operation. By applying the first delay time to the heating operation, the aerosol generating apparatus can provide a consistent preheating time (or target temperature attainment time), even when using the aerosol generating apparatus in different external environments or using different aerosol-generated articles.

[0144] In operation 1280, the aerosol generating apparatus can determine a second delay time based on the initial temperature of the heater. The aerosol generating apparatus can determine a second delay time that is positively correlated with the initial temperature of the heater. Unlike operation 1240, when the initial temperature of the heater is measured to be higher than or equal to the first temperature, the aerosol generating apparatus may not immediately perform the heating operation but may wait until the second delay time has elapsed.

[0145] In operation 1290, the aerosol generating device can perform the heating operation after a second delay time. By applying the second delay time to the heating operation, the aerosol generating device can provide a consistent preheating time (or target temperature attainment time), even when the initial temperatures of the heaters are different.

[0156] In operation 1361, the aerosol generating device can stop the heating operation for a first delay time.

[0157] In operation 1362, the aerosol generating apparatus can restart the heating operation after a first delay time. The aerosol generating apparatus can determine the first delay time based on the heating rate of the heater or the initial temperature of the heater, thereby providing a consistent preheating time (i.e., the time to reach the target temperature), even when the aerosol generating apparatus is used in different external environments or when different aerosol generating articles are used.

[0158] In operation 1370, the aerosol generating device can determine the second delay time based on the initial temperature of the heater.

[0159] In operation 1371, the aerosol generating device may perform the heating operation after a second delay time.
