Description

[Technical Field]

[0001] The present invention relates to a mobile communication terminal and a control method thereof.

[0002] More particularly, the present invention relates to a mobile communication terminal capable of generating aerosols and a method for controlling the same. [Background technology]

[0003] Conventional electronically driven aerosol generators use a device equipped with a heater to insert a stick, which is then heated by the user, generating an aerosol that is then inhaled through the mouth.

[0004] As technology advances, the number of aerosol generating devices that communicate with mobile communication terminals through communication modules is increasing.

[0005] Furthermore, some conventional aerosol generating devices are installed in communication terminals such as mobile phones (U.S. Patent Publication No. US9,894,938). The aerosol generator installed in the communication terminal is configured to receive power from a power supply (such as a battery) installed inside the communication terminal and heat the aerosol-generating material.

[0006] However, such a structure only shares a power supply and does not provide a functional or structural solution that actually embodies one integrated device.

[0007] For example, if an aerosol generating device and a mobile communication terminal are provided as a single device, many components must be placed in the space within the device, resulting in a very narrow mounting space and a reduced separation distance between components, which can lead to severe interference between the components.

[0008] This causes a problem of reduced performance and deterioration of components (display, processor, memory, etc.).

[0009] If the aerosol generating device and mobile communication terminal are provided as a single device, the stick insertion part may protrude from the current mobile communication terminal or increase the thickness of the device, which may cause inconvenience in portability.

[0010] In addition, if the aerosol generating device and the mobile communication terminal are provided as a single device, droplets may be generated in the combined mobile communication terminal, which may cause defects in other components.

[0011] Furthermore, debris of the aerosol-generating material adhering to the heating section of the aerosol-generating device creates a hygiene problem, which requires cleaning, which is inconvenient.

[0012] On the other hand, when an aerosol generating device and a mobile communication terminal are provided as a single device, depending on the combination method, it may be difficult to measure and control the temperature inside the aerosol generating unit, and as a result, device control such as PID control (Proportional-Integral-Differential control) may not be possible. Summary of the Invention [Problem to be solved by the invention]

[0013] The present disclosure is intended to solve the above-mentioned problems and to provide a mobile communication terminal and a control method thereof that allow a user to conveniently experience aerosol inhalation in various ways using the mobile communication terminal.

[0014] In addition, the present invention provides a mobile communication terminal and a control method thereof that can minimize the performance and deterioration of components even when an aerosol generating device and a mobile communication terminal are provided as a single device.

[0015] In addition, the present invention provides a mobile communication terminal and a control method thereof that can maintain portability even when an aerosol generating device and a mobile communication terminal are provided as a single device, and minimizes hygiene issues and the inconvenience of cleaning the device.

[0016] The present invention also provides a mobile communication terminal and a control method thereof that are capable of controlling the temperature in the heating unit during aerosol generation and controlling the device accordingly. [Means for solving the problem]

[0022] The mobile communication terminal also includes a display and a power supply unit, and the control unit controls the display to display information and controls the power applied to the aerosol generation unit based on the magnetic change of the susceptor.

[0023] The control unit is further configured to estimate the temperature of the susceptor based on the equivalent resistance of the aerosol generating unit, and to control the display based on the temperature of the susceptor and the estimated temperature of the display.

[0024] The control unit is also characterized in that it is configured to measure a change in a resonance frequency generated in the aerosol generation unit due to a change in temperature of the susceptor, and to control the temperature of the susceptor based on the change in the resonance frequency.

[0025] The control unit may be configured to sense a change in magnetic force generated in the aerosol generating unit due to a change in temperature of the susceptor, and to control the temperature of the susceptor based on the change in magnetic force.

[0026] The control unit is also characterized by generating first temperature information regarding the temperature of the display, controlling the display based on the first temperature information, and further acquiring second temperature information regarding the temperature of the aerosol generation unit by the stick being contained in the aerosol generation unit.

[0027] The mobile communication terminal further includes an antenna for receiving location information, the antenna being coupled to the aerosol generating unit, being positioned on the body of the aerosol generating unit, and being provided with a patch made of a conductor, and a ground spaced apart from the patch.

[0034] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Regardless of the drawing reference numerals, the same or similar components will be given the same reference numerals, and redundant description thereof will be omitted.

[0035] Hereinafter, the substance that generates the aerosol will be referred to as an aerosol-producing product (cigarette), and the explanation will be given on the assumption that the product is in the form of a stick.

[0036] FIG. 1 is a block diagram showing a mobile communication terminal according to an embodiment of the present invention.

[0037] This embodiment illustrates the logical configuration of a mobile communication terminal.

[0038] The mobile communication terminal includes, for example, a control unit 100, an aerosol generating unit 200, a power supply unit 300, a communication unit 400, a sensing unit 500, an input unit 600, an output unit 700, a memory unit 800, and an interface unit 900.

[0039] The control unit 100 controls the following components or outputs controllable signals:

[0040] The power supply unit 300 receives an external power source and an internal power source and supplies power to each component included in the mobile communication terminal under the control of the control unit 100. The power supply unit 300 includes a battery, which may be a built-in battery or a replaceable battery.

[0041] The aerosol generating unit 200 receives power from the power supply unit 300 and, under the control of the control unit 200, allows the user to generate and experience aerosol.

[0042] The aerosol generating unit 200 accommodates an aerosol product or cigarettes. Hereinafter, a cigarette is assumed to be stick-shaped, but the present invention is not limited thereto. The internal structure of the stick may also vary depending on the embodiment, and detailed embodiments of this will be described below.

[0043] The aerosol-generating unit 200 has a storage space or an insertion space, and stores an aerosol product, a cartridge, a cigarette, etc. The aerosol-generating unit 200 may have various shapes, but the following description will be given taking a pipe-shaped aerosol-generating unit as an example.

[0044] Various methods for heating the aerosol product or cigarettes can include a heater or heating element. The heater can also include multiple components, in which case it is referred to as a heater assembly or heating assembly.

[0045] The aerosol generating unit 200 heats the aerosol product or cigarettes by one of various heating methods. For example, the aerosol generating unit 200 heats the aerosol product by heating a susceptor in the receiving space using a magnetic field from a coil disposed inside the housing of the receiving space, or by directly or inductively heating the aerosol product using a heating pattern element on the housing or a heating element or pin inside the housing.

[0048] An embodiment in which the control unit 100 senses the temperature of the aerosol generating unit 200 and stably controls a system including PID (Proportional-Integral-Differential) control of a mobile communication terminal including the aerosol generating unit 200 based on the sensed temperature is shown in Figures 36 to 60.

[0049] To ensure that various functions of the mobile communication terminal can operate smoothly, the control unit 100 controls the mobile communication terminal so that the entire terminal or each part of the terminal is not significantly affected by the temperature based on the temperature obtained from the sensing unit 500, etc. Even when the aerosol generating unit 200 is operating, the control unit 100 controls the mobile communication terminal to receive appropriate power from the power supply unit 200, thereby adjusting the functions.

[0050] A detailed embodiment of this will be described below.

[0051] The communication unit 400 includes one or more modules that enable wireless communication between the mobile communication terminal and a wireless communication system, between the mobile communication terminal and another mobile communication terminal, or between the mobile communication terminal and an external server.

[0053] The communication unit 400 also includes one or more modules that connect the mobile communication terminal to one or more networks.

[0054] The communication unit 400 includes at least one of a broadcast receiving module, a mobile communication module, a wireless Internet module, a short-range communication module, and a location information module.

The broadcast channel includes a satellite channel and a terrestrial channel. Two or more broadcast receiving modules may be included in a mobile communication terminal for simultaneous broadcast reception of at least two broadcast channels or for broadcast channel switching.

[0056] The mobile communication module (not shown) transmits and receives radio signals to and from at least one of a base station, an external terminal, and a server on a mobile communication network established by a technical standard or communication method for mobile communication (e.g., GSM (Global System for Mobile communication), CDMA (Code Division Multi Access), CDMA2000 (Code Division Multi Access 2000), EV-DO (Enhanced Voice-Data Optimized or Enhanced Voice-Data Only), WCDMA (Wideband CDMA), HSDPA (High Speed ​​Downlink Packet Access), HSUPA (High Speed ​​Uplink Packet Access), LTE (Long Term Evolution), LTE-A (Long Term Evolution-Advanced), 5G NR, etc.).

The short-range wireless communication network may be a wireless personal area network. For example, the communication unit 400 recognizes data or communicates related data through NFC communication including an antenna module having a loop coil.

[0061] If the communication unit 400 includes a location information module, the location information module of the communication unit 400 is a module for acquiring the location (or current location) of the mobile communication terminal, and representative examples thereof include a Global Positioning System (GPS) module or a Wireless Fidelity (WiFi) module. For example, if the mobile communication terminal uses a GPS module, it acquires its location using signals transmitted from GPS satellites. As another example, if the mobile communication terminal uses a Wi-Fi module, it acquires its location based on information from a Wireless Access Point (AP) that transmits or receives wireless signals from the Wi-Fi module. If necessary, the location information module may alternatively or additionally perform the functions of any of the other modules of the wireless communication unit to obtain data related to the location of the mobile communication terminal. The location information module is a module used to acquire the location (or current location) of the mobile communication terminal, and is not limited to a module that directly calculates or acquires the location of the mobile communication terminal.

[0062] The antenna of the communication unit 400 may be combined with the aerosol generating unit 200 or may be a combined module. For example, the antenna of the communication unit 400 may be located on the body of the aerosol generating unit 200, and the antenna may be provided as a patch made of a conductor and a ground spaced apart from the patch. Hereinafter, a detailed embodiment of this will be described.

[0063] The sensing unit 500 includes one or more sensors for sensing at least one of information within the mobile communication terminal, information about the surrounding environment surrounding the mobile communication terminal, and user information. For example, the sensing unit 500 includes at least one of a proximity sensor, an illumination sensor, a touch sensor, an acceleration sensor, a magnetic sensor, a gravity sensor, a gyroscope sensor, a motion sensor, an RGB sensor, an infrared sensor (IR sensor), a fingerprint recognition sensor, an ultrasonic sensor, an optical sensor, a microphone, a battery gauge of a power supply, an environmental sensor (e.g., a barometer, a hygrometer, a thermometer, a radiation detection sensor, a heat detection sensor, a gas detection sensor, etc.), and a chemical sensor (e.g., an electronic nose, a health care sensor, a biometric recognition sensor, etc.).

[0064] The input unit 600 includes a camera module 610 or a video input unit for inputting a video signal, a microphone module 620 for inputting an audio signal, etc. The input unit 600 includes a user input unit for a user to input information, such as a touch key, a mechanical key, etc. The voice data and image data collected by the input unit 400 are analyzed and processed according to a user's control command.

[0065] The camera module 610 processes image frames, such as still or video images, acquired by an image sensor. The processed image frames are displayed on the display module 710 of the output unit 700 or stored in the storage unit 800.

[0066] The camera module 610 is coupled to the sensing unit 500, which includes a plurality of sensors.

[0067] The output unit 700 is for generating an output related to vision, hearing, touch, or the like, and includes a display module 710 and an audio output module 720. The output unit 700 further includes a haptic module, an optical output unit, and the like.

[0068] The display module 710 may be layered with or integrally formed with a touch sensor to implement a touch screen, which may function as a module of a user input unit that provides an input interface between the mobile communication terminal and a user, or as a module of an output unit that interfaces between the mobile communication terminal and a user.

[0069] The display module 710 includes or is connected to a touch sensor capable of sensing touch input. When the display module 710 is connected to a touch sensor, the touch sensor may be included in the sensing unit 500.

[0070] The touch sensor senses a touch (or touch input) applied to the touch screen using at least one of various touch methods such as a resistive method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method.

[0071] For example, the touch sensor is configured to convert a change in pressure applied to a predetermined location on the touch screen of the display module 710 or a change in capacitance generated at a predetermined location into an electrical input signal. The touch sensor is configured to detect the position, area, pressure at the time of touch, capacitance at the time of touch, etc., of a touch target that applies a touch to the touch screen.

[0072] The audio output module 720 outputs audio data received from the communication unit 400 or stored in the memory unit 800 in signal reception, call mode, recording mode, voice recognition mode, broadcast reception mode, etc. The audio output unit 152 can also output audio signals related to functions performed in the mobile communication terminal (e.g., signal reception sound, message reception sound, etc.). The audio output module 720 includes a receiver, a speaker, a buzzer, etc.

[0073] If the output unit 700 includes a haptic module, the haptic module generates various haptic effects that can be felt by the user. A representative example of a haptic effect generated by the haptic module is vibration. The strength and pattern of the vibration generated by the haptic module are controlled by user selection or control unit settings. For example, the haptic module may combine different vibrations and output them or output them sequentially.

[0074] If the output unit 700 includes an optical output unit, the optical output unit outputs a signal for notifying the occurrence of an event using light from a light source of the mobile communication terminal. Examples of events generated by the mobile communication terminal include receiving a message, receiving a signal, a missed call, an alarm, a schedule alarm, receiving a mail, receiving information from an application, etc.

[0075] The memory unit 800 also stores data supporting various functions of the mobile communication terminal. The memory unit 800 stores a plurality of application programs (or applications) run on the mobile communication terminal, as well as data and commands for the operation of the mobile communication terminal. At least some of these application programs are downloaded from an external server via wireless communication. At least some of these application programs exist on the mobile communication terminal from the time of delivery for the basic functions of the mobile communication terminal (e.g., incoming call, outgoing call, message reception, outgoing call functions).

[0101] FIG. 3 is an exploded view showing an embodiment of a mobile communication terminal.

[0102] The exploded view of the mobile communication terminal includes a main body 1110 and a rear frame 1210. The rear frame 1210 is separated from a camera frame 1220.

[0103] Camera frame 1220 provides a frame in which a camera module array including a first camera module 1221, a second camera module 1225, and a third camera module 1227 is positioned.

[0104] An antenna module 1310 for wireless communication is located below the main body 1110.

[0105] The main body 1110 includes a circuit board set having a first circuit board 1410 , a second circuit board 1420 , a third circuit board 1430 and a fourth circuit board 1440 .

[0106] Each circuit board includes various chips on both sides that perform control functions. For example, the first circuit board 1410 includes a front-end chip for communications and an audio amplifier chip. The second circuit board 1420 includes a mobile processor, a communications modulator, a power control chip, and memory.

[0107] A third circuit board 1430 contains a camera control module that controls the camera module array, and a fourth circuit board 1440 is mounted with a laser control chip for the camera module array.

[0108] The loop coil module 1730 includes a coil and its control circuit for short-range wireless antenna communication and wireless charging.

[0109] A fifth circuit board 1710 contains circuitry for audio output, and a battery module 1910 for providing power is included in the main body 1110 .

[0110] Meanwhile, the aerosol-generating unit 1100 is located at the top of the main body 1110 and is electrically connected to the circuit board set of the main body 1110. The aerosol-generating unit 1100 accommodates a stick S containing an aerosol product and cigarettes.

[0111] In this embodiment, a cylindrical aerosol-generating unit 1110 and a stick are shown, but they may be modified depending on the embodiment. In the following embodiment, for convenience, a cylindrical aerosol-generating unit 1110 and a stick are used as an example.

[0112] Hereinafter, an embodiment of the aerosol generating unit of the mobile communication terminal will be described in detail.

[0113] The aerosol generating unit serves to generate aerosol by electrically heating cigarettes contained in the internal space.

[0114] The aerosol generating unit 200 includes a heater. In one embodiment, the heater is an electrically resistive heater. For example, the heater includes an electrically conductive track, and when an electric current is passed through the electrically conductive track, the heater heats up.

[0115] The heater may include 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 depending on the shape of the heating element, examples of which are described in detail below.

[0116] Cigarettes include a tobacco rod and a filter rod. The tobacco rod may be manufactured as a sheet, a strand, or a shredded tobacco sheet. The tobacco rod may also be surrounded by a heat-conductive material.

[0117] For example, but not limited to, the thermally conductive material is a metal foil such as aluminum foil.

[0118] The filter rod may be a cellulose acetate filter. The filter rod may be composed of at least one segment. For example, the filter rod may include a first segment that cools the aerosol and a second segment that filters out selected components contained in the aerosol.

[0119] In other embodiments, the aerosol generator may generate the aerosol using a cartridge containing the aerosol-generating material.

[0120] The aerosol generating unit includes a cartridge having an aerosol-generating material and a body supporting the cartridge. The cartridge may be detachably coupled to the mobile communication terminal or the aerosol generating unit, but is not limited thereto. The cartridge may be integrally formed or assembled with the mobile communication terminal or the aerosol generating unit and fixed so as not to be detachable by the user. The cartridge is attached to the body with the aerosol-generating material contained therein. However, without being limited thereto, the aerosol-generating material may be injected into the cartridge while the cartridge is coupled to the mobile communication terminal or the aerosol generating unit.

[0121] The cartridge contains an aerosol-forming material in any one of a variety of states, such as liquid, solid, gas, or gel. The aerosol-forming material includes a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing substance including a volatile tobacco flavor component, or a liquid containing a non-tobacco substance.

[0122] The cartridge is activated by an electrical or wireless signal transmitted from the main body to convert the phase of the aerosol-generating material inside the cartridge into a gas phase, thereby generating an aerosol. The aerosol refers to a gas mixture of vaporized particles generated from the aerosol-generating material and air.

[0123] In another embodiment, the aerosol mobile communication terminal or the aerosol generating unit heats the liquid composition to generate an aerosol, and the generated aerosol passes through the cigarette and is delivered to the user. That is, the aerosol generated from the liquid composition moves along the airflow passage of the aerosol generating unit, and the airflow passage is configured to allow the aerosol to pass through the cigarette and be delivered to the user.

[0124] In another embodiment, an aerosol is generated from an aerosol-generating material using an aerosol mobile communication terminal or an aerosol generator and an ultrasonic vibration method, where the ultrasonic vibration method refers to a method of generating an aerosol by atomizing the aerosol-generating material using ultrasonic vibration generated by a vibrator.

[0125] The aerosol generating unit includes a vibrator that generates short-period vibrations to atomize the aerosol generating material. The vibrations generated by the vibrator may be ultrasonic vibrations, and the frequency band of the ultrasonic vibrations is approximately 100 kHz to 3.5 MHz, but is not limited to this.

[0126] The aerosol-generating unit further includes a wick that absorbs the aerosol-generating substance. For example, the wick is disposed so as to surround at least a region of the vibrator or so as to contact at least a region of the vibrator.

[0127] When a voltage (e.g., an AC voltage) is applied to the vibrator, heat and / or ultrasonic vibrations are generated from the vibrator, and the heat and / or ultrasonic vibrations generated from the vibrator are transferred to the aerosol-forming substance absorbed in the wick. The aerosol-forming substance absorbed in the wick is converted into a gas phase by the heat and / or ultrasonic vibrations transferred from the vibrator, resulting in the generation of an aerosol.

[0128] For example, the heat generated from the vibrator reduces the viscosity of the aerosol-generating substance absorbed in the core, and the ultrasonic vibrations generated from the vibrator break the reduced viscosity aerosol-generating substance into fine particles, thereby generating an aerosol, but this is not limitative.

[0129] In another embodiment, the aerosol generating unit may generate the aerosol by heating the aerosol product accommodated in the aerosol generating unit using induction heating.

[0130] The aerosol generating unit includes a susceptor and a coil. In one embodiment, the coil applies a magnetic field to the susceptor. When power is supplied from the aerosol generating unit to the coil, a magnetic field is formed inside the coil. In one embodiment, the susceptor may be a magnetic material that generates heat when an external magnetic field is applied. When the susceptor is located inside the coil and a magnetic field is applied, heat is generated, thereby heating the aerosol product. Alternatively, the susceptor may be located inside the aerosol product.

[0131] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, with reference to the accompanying drawings, embodiments of the present invention will be described in detail so that those skilled in the art can easily carry out the present invention.

[0132] An example including a heater that heats the aerosol-generating substance by a non-contact external induction method will be described below.

[0133] FIG. 4 is a cross-sectional view of an embodiment of an aerosol generation module taken in one direction.

[0134] The aerosol generating unit 200 includes a heater that heats an aerosol product inserted into the pipe-shaped internal space in one of various ways.

[0135] Here, the aerosol generating unit 200 according to one embodiment includes an inner cylinder 2200 , a first support unit 2210 , a second support unit 2220 and a heater 2300 .

[0136] The inner barrel 2200 is located in the interior space of the housing 2100. The inner barrel 2200 includes a storage space 2205 for storing the aerosol production product 220.

[0137] The receiving space 2205 not only receives the aerosol generating product 220 but also serves as a passageway through which air flows in from the outside. An internal passageway 2202 is formed between the internal cylinder 2200 and the heater 2300 so that air flowing into the receiving space 2205 through an inlet passageway (not shown) of the first support part 2210 can flow to the second support part 2220. The air flowing into the receiving space 2205 travels along the internal passageway 2202 and reaches the second support part 2220.

[0138] The first support part 2210 is disposed at the entrance of the storage space 2205 and supports at least a portion of the aerosol product 220 housed in the storage space 2205. The first support part 2210 also allows air existing outside the aerosol generating part 200 to flow into the storage space 2205.

[0139] The first support part 2210 includes a support (not shown) for supporting at least a part of the aerosol production product and an inflow passage for allowing air outside the aerosol-generating part 200 to flow into the receiving space 2205 .

[0140] The first support part 2210 includes a puff sensing hole 2211 that is connected to the puff sensor 2330. The puff sensing hole 2211 is disposed at the lower end of the puff sensor 2330 adjacent to the first support part 2210. Air that has passed through the inlet passage passes through the puff sensing hole 2211 and enters the puff sensor 2330.

[0141] The puff sensing hole 2211 narrows toward the puff sensor 2330, but is not limited to this.

[0142] The second support portion 2220 is disposed inside the receiving space 2205 and supports the end portion of the aerosol production product 220. In addition, the second support portion 2220 allows air present inside the receiving space 2205 to flow into the aerosol production product 220.

[0143] The second support 2220 includes a communication passage (not shown) that allows air in the receiving space 2205 to flow into the aerosol producing article.

[0144] One end of the heater 2300 is inserted into the second support portion 2220. In this way, the heater 2300 is supported by the second support portion 2220.

[0145] The connecting portion 2230 is connected to the lower end of the first support portion 2210 .

[0146] The coupling part 2230 includes a first air hole (not shown) that allows the air that has passed through the inflow passage of the first support part 2210 to flow into the receiving space 2205 .

[0147] When the coupling part 2230 and the first support part 2210 are coupled together, a puff sensing passage 2301 is formed between the upper end of the coupling part 2230 and the first support part 2210. The puff sensing passage 2301 connects the inlet passage and the puff sensor 2330. Air that has passed through the inlet passage of the first support part 2210 passes through the puff sensing passage 2301 and flows into the puff sensor 2330 adjacent to the first support part 2210.

[0148] According to one embodiment, air traveling along puff sensing passageway 2301 passes through puff sensing hole 2211 in first support portion 2210 and reaches puff sensor 2330 .

[0149] A portion of the coupling portion 2230 surrounds the outer periphery of the inner tube 2200. Other components outside the coupling portion 2230 contact the portion of the coupling portion 2230 described above and are supported by the coupling portion 2230.

[0150] Another part of the coupling part 2230 is open, which allows the aerosol-generating part 200 to have a space therein in which other components can be placed.

[0151] The coupling portion 2230 further includes a guide 2310 that guides the insertion of the aerosol production article 220 .

[0152] At least a portion (e.g., the upper end) of the guide 2310 may be chamfered to prevent the aerosol product 220 from getting caught on the guide 2310 and interfering with the insertion when the aerosol product 220 is inserted into the aerosol generating unit 200. The chamfered portion has a sloped or rounded shape.

[0153] In other embodiments, the guide 2310 supports at least a portion of the outer periphery of the aerosol production article 220 .

[0154] One end (for example, the upper end) of the inner tube 2200 is inserted into the connecting portion 2230. In this way, the inner tube 2200 is supported by the connecting portion 2230.

[0155] The outer tube 2250 is positioned at a distance from the outer side of the inner tube 2200 .

[0156] The outer cylinder 2250 prevents the heat generated by the heater 2300 from being transferred to the outside. To improve the efficiency of heat insulation, the outer cylinder 2250 has a double-wall structure.

[0157] The outer cylinder 2250 includes an inner wall 2251 facing the inner cylinder 2200, an outer wall 2252 spaced from the inner wall 2251 toward the outside of the outer cylinder 2250, and a heat insulating space 2253 formed between the inner wall 2251 and the outer wall 2252. The heat insulating space 2253 may be placed in a vacuum state to minimize heat transfer to the outside of the aerosol generating unit 200. Here, the "vacuum state" does not only mean a state where there is no air at all, but also includes a state where the pressure is lower than the surrounding atmospheric pressure.

[0158] The outer tube 2250 includes a through hole (not shown) at the bottom end thereof. One or more electric wires or magnetic field generators 2310 are discharged to the outside of the outer tube 2250 through the through hole of the outer tube 2250.

[0159] The inner barrel 2200 includes one or more supports 2201 that contact the lower end of the inside of the outer barrel 2250. The supports 2201 position the inner barrel 2200 at a distance toward the inside of the outer barrel 2250 and support the inner barrel 2200 by the outer barrel 2250 in the length direction, which is the direction in which the aerosol production article 220 is inserted.

[0160] The shielding portion 2260 is disposed so as to surround at least a portion of the outer circumferential surface of the coupling portion 2230. The shielding portion 2260 is in contact with at least a portion of the outer circumferential surface of the coupling portion 2230 and is supported by the coupling portion 2230.

[0161] The shielding part 2260 prevents the induced magnetic field generated inside the aerosol generating part 200 from leaking to the outside of the aerosol generating part 200 .

[0162] The shielding portion 2260 includes a wiring hole (not shown) that is open in the radial direction of the accommodation space 2205 so that the temperature sensing wiring 2320 can pass through.

[0163] The sealing portion 2270 is disposed at the lower end of the outer cylinder 2250 and can prevent leakage of liquid. The sealing portion 2270 includes an elastic material such as rubber or silicone.

[0164] The sealing portion 2270 includes a wiring passage (not shown) through which one or more electrical wires or magnetic field generators 2310 pass. The one or more electrical wires or magnetic field generators 2310 are led out of the sealing portion 2270 through the wiring passage of the sealing portion 2270.

[0165] The heater 2300 is disposed inside the storage space 2205. The heater 2300 accommodates at least a portion of the aerosol production product 220 inserted inside the housing 2100. The heater 2300 supports the outer peripheral surface of the aerosol production product 220 accommodated in the storage space 2205.

[0166] Heater 2300 generates heat when power is supplied to it, and at least a region of the contained aerosol production article 220 is heated by heater 2300. When aerosol production article 220 is heated, vaporized particles generated from aerosol production article 220 are mixed with air in the interior space of housing 2100 to generate an aerosol.

[0167] The aerosol generation unit 200 according to one embodiment includes a magnetic field generator 2310. In this case, the heater 2300 becomes a susceptor.

[0168] The magnetic field generator 2310 is coupled to the inner cylinder 2200. For example, the magnetic field generator 2310 is attached to the outside of the inner cylinder 2200.

[0169] The magnetic field generator 2310 heats at least a region of the aerosol product 220 contained in the containing space 2205 by induction heating.

[0170] The magnetic field generator 2310 is disposed so as to surround the outer periphery of the susceptor 2300, and generates an induction magnetic field toward the susceptor 2300 by power supplied from a battery (not shown).

[0171] The susceptor 2300 is disposed so as to surround at least a portion of the outer circumferential surface of the aerosol product 220 accommodated in the accommodation space 2205. The susceptor 2300 generates heat by the alternating magnetic field generated by the magnetic field generator 2310, thereby heating the aerosol product accommodated in the accommodation space 2205.

[0172] As another example of the heater 2300, the aerosol generating unit 200 includes an electrical resistance heater, such as a film heater arranged to surround at least a portion of the outer periphery of the aerosol production product inserted inside the housing 2100. The film heater includes an electrically conductive track, and when an electric current flows through the electrically conductive track, the film heater generates heat and heats the aerosol production product inserted into the housing 2100.

[0173] As another example of the heater 2300, the aerosol generating unit 200 includes at least one of a needle heater, a rod heater, and a tubular heater that can heat the inside of the aerosol product inserted into the housing 2100. The heaters described above are inserted into at least one region of the aerosol product, for example, to heat the inside of the aerosol product.

[0174] The heater 2300 is not limited to the specific embodiment described above, and the heater may be modified into various forms to heat the aerosol product 220 to a designated temperature. In the present invention, the "designated temperature" refers to a temperature at which the aerosol-generating material contained in the aerosol product 220 is heated to generate an aerosol. The designated temperature may be a temperature preset in the aerosol-generating unit 200. Alternatively, the designated temperature may be changed depending on the type of the aerosol-generating unit 200 and / or a user operation.

[0175] The temperature sensing wire 2320 is an example of a temperature sensor. The temperature sensing wire may be a thermocouple. As another example, the temperature sensing wire is a thermally conductive wire for transferring heat, and a sensor module that generates a signal in response to a temperature change is connected to the temperature sensing wire.

[0176] A portion of the temperature sensing wire 2320 may be coupled to the heater 2300. The temperature sensing wire 2320 detects a change in the temperature of the heater 2300 while the heater is in operation.

[0177] The temperature sensing wire 2320 is drawn out from the receiving space 2205 to the outside of the inner tube 2200 through the space between the inner tube 2200 and the coupling part 2230. The temperature sensing wire 2320 is extended through the space between the inner tube 2200 and the outer tube 2250.

[0178] The other part of the temperature sensing wire 2320 passes through the external cylinder 2250 via a through hole in the external cylinder 2250 and is drawn out to the outside of the external cylinder 2250 .

[0179] The heater 2300 further includes a protruding portion 301 protruding outward. A portion of the temperature sensing wire 2320 is connected to the protruding portion 301 of the heater 2300.

[0180] The puff sensor 2330 detects a change in pressure in the airflow passage caused by a puff action by the user. The puff sensor 2330 is disposed adjacent to the first support portion 2210.

[0181] The positions and shapes of the above-described components are not limited to this embodiment and can be modified in various ways.

[0182] FIG. 5 is another cross-sectional view of an embodiment of the aerosol generation module.

[0183] The same reference numerals as those in the above-described embodiment denote the same components, and the same description as that of the above-described embodiment will be omitted.

[0184] The embodiment shown in this figure shows that the aperture 2254 of the outer barrel 2250 and the wiring passage 2270 of the sealing portion 2270 are located away from the central longitudinal axis of the aerosol production article 220 .

[0185] At least a portion of the sealing portion 2270 is inserted into the through hole 2254 of the outer barrel 2250. One or more electrical wires or magnetic field generators 2310 pass through the through hole 2254 of the outer barrel 2250 and through the wire passage 2272 of the sealing portion 2270.

[0186] FIG. 6 is an enlarged cross-sectional view of some components of one embodiment of an aerosol generation module.

[0187] This figure shows the process of air movement due to a user's puffing action in an embodiment of an aerosol generating module.

[0188] When a user touches the aerosol generating product 220 with their mouth and performs a puffing action, a pressure difference occurs between the outside of the aerosol generating module and the internal space of the housing 2100, and external air flows into the inside of the housing 2100 through the first support part 2210.

[0189] External air flowing into the housing 2100 passes through the inlet passage 2204 of the first support part 2210. The air passing through the inlet passage 2204 passes through the first air hole 2231 and the second air hole 2241 and reaches the internal passage 2202 between the internal cylinder 2200 and the heater 2300. The air moving along the internal passage 2202 flows into the second support part 2220.

[0190] The air flowing into the transmission passage 2227 of the second support part 2220 passes through the transmission passage 2227 in a U-shape along the shape of the second support part 2220 and flows into the end of the aerosol product 220 inserted into the storage space 2205.

[0191] The air flowing into the aerosol-producing product 220 can be mixed with vaporized particles generated as the aerosol-producing product 220 is heated to generate an aerosol. The user inhales the generated aerosol from the receiving space 2205 by puffing the aerosol-producing product 220.

[0192] FIG. 7 is a diagram illustrating the process of air movement in the second support part 2220 according to an embodiment of the present invention.

[0193] When an aerosol production product (not shown) is inserted into the aerosol generation section 200 and comes into contact with the inner surface of the second support section 2220, a transmission passage 2227 is formed in the space between the second support section 2220 and the aerosol production product (not shown).

[0194] The air that has moved along the internal passage 2002 between the internal cylinder 2200 and the heater 2300 flows into the transfer passage 2227 of the second support part 2220. The transfer passage 2227 has a U-shape that matches the shape of the second support part 2220. The air that has moved along the transfer passage 2227 reaches the end of the aerosol product.

[0195] However, the arrangement and shape of the transmission passage 2227 are not limited to the above-described embodiment, and can be modified in various ways.

[0196] Here, an example is shown in which the aerosol generating unit 200 heats the aerosol product by using a film-type heater outside the product.

[0197] As described above, the aerosol generating unit 200 includes a heater that heats an aerosol product inserted into the pipe-shaped internal space in one of various ways.

[0198] FIG. 8 is a diagram illustrating an example in which a stick is inserted into an aerosol generating unit of a mobile communication terminal according to an embodiment of the present invention.

[0199] Referring to this figure, the aerosol generating unit 200 includes a heating assembly 2530 shown as a dotted cylinder in the figure, and the aerosol generating unit 200 is connected to the control unit 100 and power supply unit 300 of the mobile communication terminal described above.

The control unit 100 checks the status of each component of the aerosol generating unit 200 and determines whether the aerosol generating unit 200 is in an operable state.

[0206] A cartridge (not shown) stores a liquid. The cartridge generates an aerosol from the stored liquid. The aerosol generated in the cartridge is delivered to the user through a stick 210 inserted into the aerosol generating unit 200.

[0207] The cartridge includes a liquid chamber for storing a liquid and an atomization chamber through which air passes and through which an aerosol is generated. The cartridge includes a wick disposed within the atomization chamber to which liquid is supplied from the liquid chamber. The cartridge 40 includes a heating coil for heating the wick to generate the aerosol. Air flowing into the cartridge inlet passes through the liquid chamber, carrying the aerosol with it, and is discharged through the cartridge outlet.

[0208] The lower end of the stick 210 is inserted into the insertion space 2540, and the upper end is exposed to the outside from the insertion space 2540. The user holds the exposed upper end of the stick 210 in their mouth and inhales air. The air passes through the inside of the aerosol generating unit 200 and is provided to the user together with the aerosol.

[0209] 9 and 10 are diagrams showing an example of the structure of an aerosol generating unit 200 capable of accommodating a stick according to an embodiment of the present invention.

[0210] Referring to these figures, the lower pipe 2502 is inserted into the lower side of the upper pipe 2501. The heating assembly 2530 is inserted into the upper pipe 2501. The heating assembly 2530 is disposed between the upper end of the upper pipe 2501 and the upper end of the lower pipe 2502.

[0211] The heating assembly 2530 has a pipe shape extending in the vertical direction. The heating assembly 2530 has a cylindrical shape. The heating assembly 2530 has a first insertion space 2541 formed therein. The first insertion space 2541 has a cylindrical shape extending in the vertical direction. The first insertion space 2541 is open at the top and bottom. The upper end of the first insertion space 2541 is open to the outside.

The heating element 2430 is an electric resistance heater. The heating element 2430 is made of a conductive metal.

[0216] The heating assembly 2530 includes a heat insulating layer 2440. The heat insulating layer 2440 has a cylindrical shape that extends in the vertical direction. The heat insulating layer 2440 surrounds the outer periphery of the heating element 2430. The heat insulating layer 2440 can prevent heat generated from the heating element 2430 from radiating outward instead of into the first insertion space 2541.

[0217] The first connector 2450 extends downward from the lower end of the heating element 2430. The first connector 2450 is formed integrally with the heating element 2430. The first connector 2450 is made of a conductive metal. The first connector 2450 is connected to the second connector 2460, which is connected to the power supply unit 300 and / or the control unit 100. The second connector 2460 sends power to the first connector 2450. This supplies power to the heating element 2430.

[0218] 11 and 12 are diagrams showing a portion of an aerosol generating device in which heating is performed by a film-type heater outside the aerosol product.

[0219] Referring to these figures, the periphery 2521 of the lower pipe 2502 is cylindrical and extends in the vertical direction. The lower pipe 2502 is disposed inside and below the upper pipe 2501. The periphery 2521 is also referred to as a side wall.

[0220] The lower pipe 2502 has a second insertion space 2562. A periphery 2521 of the lower pipe 2502 surrounds the periphery of the second insertion space 2562. The second insertion space 2562 is cylindrical and open at the top and bottom.

[0221] The light absorbing portion 2523 is formed on the outer peripheral surface of the peripheral edge 2521 at the top of the lower pipe 2502. The light absorbing portion 2523 extends in the circumferential direction along the outer peripheral surface of the peripheral edge 2521. The light absorbing portion 2523 is "C" shaped or "O" shaped. The light absorbing portions 2523 face radially outward.

[0222] The first support rib 2525 is formed on the upper part of the outer peripheral surface of the peripheral edge 2521 of the lower pipe 2502. The first support rib 2525 is formed around the light absorbing portion 2523. The first support rib 2525 protrudes radially outward from the upper end and / or lower end of the light absorbing portion 2523 and faces upward. However, the position of the first support rib 2525 is not limited thereto. The first support rib 2525 extends in the circumferential direction along the light absorbing portion 2523. The first support rib 2525 forms a step on the peripheral edge 2521.

[0223] An upper end surface 2522 of the peripheral edge 2521 of the lower pipe 2502 extends in the circumferential direction along the peripheral edge 2521. The upper end surface 2522 faces the upper side of the lower pipe 2502. The upper end surface 2522 is "C" shaped or "O" shaped.

[0224] The heater support rib 2526 is formed on the upper end of the circumferential edge 2521 of the lower pipe 2502. The heater support rib 2526 is formed by recessing the upper end of the inner circumferential surface of the circumferential edge 2521 of the lower pipe 2502 radially outward. The heater support rib 2526 forms a step on the upper end of the inner circumferential surface of the circumferential edge 2521 of the lower pipe 2502. The heater support rib 2526 is adjacent to the upper end surface 2522. The heater support rib 2526 faces the second insertion space 2562 radially inward.

[0225] One side of the periphery 2521 of the lower pipe 2502 is recessed radially inward to form a recessed groove 5244. The recessed groove 5244 extends to the upper end surface 2522 of the periphery 2521 of the lower pipe 2502. The recessed groove 5244 is formed between both ends of the "C"-shaped light absorbing portion 2523. One side of the periphery 2521 of the lower pipe 2502 is opened to form a connecting hole 5243. The connecting hole 5243 is located below the recessed groove 5244.

[0226] The first connector 2450 is inserted into the recessed groove 5244. The first connector 2450 and / or the second connector 2460 pass through the connecting hole 5243 and are connected to each other.

[0228] The support bar 2529 extends upward from the base 2528 along the periphery 2521 of the lower pipe 2502. The support bar 2529 protrudes radially outward from the periphery 2521. The support bar 2529 is formed on both sides of the lower pipe 2502.

[0229] The inlet 5422 is formed by opening a lower portion on one side of the periphery 2521 of the lower pipe 2502. The inlet 5422 communicates with the connecting channel.

[0230] The following embodiment describes an aerosol generating unit that is a heater for heating a stick containing an aerosol product, and includes a film-type heating pattern heater and a sensor pattern for temperature control.

[0231] The control unit 100 controls the power supplied from the power supply unit 110 to the heater assembly 2630 based on the temperature measured using a sensor pattern described below.

[0232] Here, the heater assembly 2630 performs the heating function similarly to the heating assembly 2530 described above, but since it includes a heat generating pattern or a sensor pattern, it is specifically referred to as the heater assembly 2630 in order to distinguish the heater type.

[0233] The control unit 100 checks the state of each of the components included in the aerosol generation unit 200 and determines whether the aerosol generation unit 200 is in an operable state.

[0234] The aerosol generating unit 200 includes a substrate on which a circuit for transmitting an electrical signal transmitted from the control unit 100 is printed inside the body of the aerosol generating unit 200 .

[0235] Accordingly, the heater assembly 2630 may be electrically connected to the control unit 100, the power supply unit 110, and a substrate, or the control unit 100 may include a substrate that performs this function.

[0236] The substrate connects the aerosol generating unit 200 and the control unit 100 via a bridge. Depending on the implementation, the bridge may be included in the aerosol generating unit 200, the control unit 100, or a substrate connected to the control unit 100.

[0237] The bridge is provided inside the body of the aerosol generating unit 200. Thus, the bridge electrically connects the heater assembly 2630 and the substrate.

[0238] The bridge is disposed between the heater assembly 2630 and the substrate 121. The bridge includes an electrically conductive pattern. The bridge is formed of a material with low thermal conductivity. The bridge is made of a material with a thermal conductivity lower than that of the heater assembly 2630. The bridge is made of a material with a temperature coefficient of resistance (TCR) lower than that of the heater assembly 2630.

[0239] As a result, power is transferred to the heater assembly 2630 via the bridge, but the amount of heat generated by the heater assembly 2630 transferred to the substrate via the bridge is reduced, preventing the substrate from overheating and causing malfunction or breakdown. Also, heating of the surroundings other than the heater assembly 2630 can be prevented.

[0240] FIG. 13 is a diagram showing another embodiment of the aerosol generating unit.

[0241] Referring to this figure, a pipe 2601 forming the body of the aerosol generating unit 200 is hollow and has an insertion space 2604 therein. The insertion space 2604 is open to one side and the other side of the pipe 2601.

[0242] One side of the insertion space 2604 is open to the outside. The stick 210 is inserted into the pipe 2601 through the opening of the insertion space 2604. The insertion space 2604 has a cylindrical shape that is long in the vertical direction.

[0243] In this embodiment, the pipe 2601 forming the body of the aerosol generating unit 200 includes an upper pipe and a lower pipe.

[0244] In order to distinguish such heaters as they include a heating pattern or a sensor pattern, the pipe 2601 forming the body of the aerosol generation unit 200 is described herein as including a first pipe section 2602 and a second pipe section 2603.

[0245] A first pipe section 2602 and a second pipe section 2603 are joined or assembled together to form a pipe 2601 .

[0246] The first pipe section 2602 is located above the second pipe section 2603. The inner circumferential surface of the first pipe section 2602 surrounds the upper part of the insertion space 2604, and the inner circumferential surface of the second pipe section 2603 surrounds the lower part of the insertion space 2604. The lower end of the second pipe section 2603 is opened to form an inlet 2605.

[0247] The inlet 2605 communicates with the insertion space 2604. Air flows into the insertion space 2604 through the inlet 2605.

[0248] The heater assembly 2630 is placed inside the pipe 2601 and fixed thereto.

[0249] The upper periphery of the heater assembly 2630 is covered by the upper periphery of the pipe 2601 .

[0250] The outer circumferential surface of the heater assembly 2630 is covered by the inner circumferential surface of the pipe 2601. The heater assembly 2630 surrounds at least a portion of the insertion space 2604. The inner circumferential surface of the heater assembly 2630 forms the insertion space 2604. The heater assembly 2630 heats the insertion space 2604.

[0251] FIG. 14 is a cutaway view of the second layer 2722 of an embodiment of an aerosol-generating portion.

[0252] The inner pipe 2710 is made of a thermally conductive material.

[0253] The inner pipe 2710 may be made of a conductive or non-conductive material and may be made of various materials with excellent thermal conductivity.

[0254] The inner pipe 2710 may have an appropriate strength to maintain the shape of the insertion space 2604 in which the stick 210 is accommodated, and an appropriate thickness to efficiently transfer heat from the heating pattern 2730.

[0255] The first layer 2721 covers the inside of the heating pattern 2730 and the sensor pattern 2740 .

[0256] The first layer 2721 has electrical insulation properties and heat resistance sufficient to withstand the heat generated from the heating pattern 2730.

[0257] The first layer 2721 is made of paper, glass, ceramic, or coated metal.

[0258] The first layer 2721 may be made of a variety of suitable materials and is not limited to the examples described above.

[0259] The second layer 2722 covers the outside of the heating pattern 2730 and the sensor pattern 2740. The second layer 2722 has electrical insulation properties. The second layer 2722 has heat resistance sufficient to withstand the heat generated from the heating pattern 2730.

[0260] The second layer 2722 has thermal insulating properties and can reduce heat loss from the heater assembly 2630 to the outside.

[0261] The heater assembly 2630 includes a heating pattern 2730. The heating pattern 2730 is printed integrally on the first layer 2721. The heating pattern 2730 is formed between the first layer 2721 and the second layer 2722. The heating pattern 2730 is realized using an electrically resistive element. The electrically resistive heating element generates heat when power is supplied from the power supply unit 110 and an electric current flows through the electrically resistive heating element. The heating pattern 2730 is made of aluminum, tungsten, gold, platinum, silver, copper, nickel, palladium, or a combination thereof.

[0262] The heating pattern 2730 may include, but is not limited to, an alloy. The resistance value of the heating pattern 2730 can be set in various ways depending on the constituent material, length, width, thickness, or pattern of the electrical resistive element.

[0263] The heating pattern 2730 can be made of a material with a low temperature coefficient of resistance.

[0264] A low temperature coefficient of resistance reduces power loss during heating and increases heat transfer efficiency. For example, heating pattern 2730 is made of constantan. Constantan is an alloy made of nickel and copper in a ratio of 45% and 55%, respectively. Constantan has a temperature coefficient of resistance of 0.000008, which converges to zero.

[0265] This allows the heat generating pattern 2730 to generate heat and transfer the heat to the insertion space 2604 with high efficiency.

[0266] The heater assembly 2630 includes a sensor pattern 2740. The sensor pattern 2740 is printed integrally with the heating pattern 2730 on the first layer 2721. The sensor pattern 2740 is located between the first layer 2721 and the second layer 2722. The sensor pattern 2740 is formed by printing a resistor having a temperature coefficient of resistance. The sensor pattern 2740 is formed adjacent to and between the heating patterns 2730.

[0267] The sensor pattern 2740 is made of at least one material selected from the group consisting of ceramic, semiconductor, metal, and carbon. The sensor pattern 2740, like the heating pattern 2730, is made of an electrically resistive element or an electrically conductive element.

[0268] The electrical resistance of the resistor of the sensor pattern 2740 changes depending on the temperature. The change in resistance is derived by passing a current through the resistor of the sensor pattern 2740 and measuring the change in voltage value. In this way, the change in electrical resistance of the sensor pattern 2740 due to the temperature change is measured, and the temperature of the heater assembly 2630 is measured. However, this is not limiting, and the change in resistance can also be derived by applying a voltage to the resistor of the sensor pattern 2740 and measuring the change in current value.

[0269] The first terminal 2731 is formed at the end of the heating pattern 2730. The first terminal 2731 electrically connects the heating pattern 2730 to the power supply unit 110. The first terminal 2731 serves as an electrical connection terminal that provides power supplied from the power supply unit 110 to the heating pattern 2730. The first terminal 2731 is exposed to the outside from the heater assembly 2630.

[0270] The second terminal 2741 is formed at the end of the sensor pattern 2740. The second terminal 2741 electrically connects the sensor pattern 2740 to the power supply unit 110. The second terminal 2741 serves as an electrical connection terminal that provides power supplied from the power supply unit 110 to the sensor pattern 2740. The second terminal 2741 is exposed to the outside from the heater assembly 2630.

[0271] The terminal portion 2735 extends from the layer 2720 to one side. The terminal portion 2735 is exposed from the layer 2720. The heating pattern 2730 extends from the layer 2720 to the terminal portion 2735 and is printed on the terminal portion 2735. The first terminal 2731 is formed at an end of the heating pattern 133 and is located on the terminal portion 2735. The sensor pattern 2740 extends from the layer 2720 to the terminal portion 2735 and is printed on the terminal portion 2735. The second terminal 2741 is formed at an end of the sensor pattern 2740 and is located on the terminal portion 2735.

[0272] 15 to 17 are diagrams showing the coupling circuits and blocks of the aerosol generating unit.

[0273] Referring to these figures, the aerosol generating unit 200 includes a first substrate 2621. The first substrate 2621 transmits electrical signals to control the operation of various components. A circuit pattern for transmitting the electrical signals is formed on the first substrate 2621. The first substrate 2621 is electrically connected to the power supply unit 300 and the control unit 100. The control unit 100 is mounted on the first substrate 2621. The first substrate 2621 is also referred to as a main substrate.

[0274] The aerosol generation unit 200 includes a bridge 2650. The bridge 2650 electrically connects the heater assembly 2630 and the first substrate 2621. One end of the bridge 2650 is coupled to a terminal portion 2735 of the heater assembly 2630. The other end of the bridge 2650 is coupled to the first substrate 2621.

[0275] The bridge 2650 includes a second substrate 2651. The second substrate 2651 is also referred to as a connecting substrate. The second substrate 2651 extends from the heater assembly 2630 to the first substrate 2621. The second substrate 2651 is formed of a flexible printed circuit board (FPCB). Because the second substrate 2651 is flexible, it can be easily installed inside the aerosol generation unit 200.

[0276] The bridge 2650 includes a connecting pattern 2650 printed on a second substrate 2651. The connecting pattern 2650 extends from one end to the other end of the second substrate 2651. The connecting pattern 2650 is made of an electrically conductive material.

[0277] A plurality of connecting patterns 2650 are formed corresponding to the first terminals 2731 and the second terminals 2741. The connecting patterns 2650 are covered with a layer having electrical and thermal insulation properties.

[0278] The bridge 2650 includes a connecting terminal 2653. The connecting terminal 2653 is located at one end of the bridge 2650. The connecting terminal 2653 is formed at one end of each of the connecting patterns 2650. A plurality of connecting terminals 2653 are provided corresponding to the first terminals 2731 and the second terminals 2741. The connecting terminals 2653 contact and are electrically connected to the first terminals 2731 and the second terminals 2741 of the terminal unit 2735. The connecting terminals 2653 are coupled or joined to the first terminals 2731 and the second terminals 2741. For example, the connecting terminals 2653 are joined to the first terminals 2731 and the second terminals 2741 by soldering.

[0279] The bridge 2650 includes a connector 2654. The connector 2654 is formed at the other end of the connecting pattern 2650. The connector 2654 faces the connecting terminal 2653 of the connecting pattern 2650. The connector 2654 is coupled to the first substrate 2621, and couples the connecting pattern 2650 of the bridge 2650 to the first substrate 2621.

[0280] As a result, the first substrate 2621 and the heater assembly 2630 are electrically connected to each other. The power supply unit 110 connected to the first substrate 2621 supplies power to the heater assembly 2630 via the bridge 2650.

[0281] The heater assembly 2630 is made of a material having a temperature coefficient of resistance lower than that of the bridge 2650. The heating pattern 2730 is made of a material having a temperature coefficient of resistance lower than that of the connecting pattern 2650 of the bridge 2650.

[0282] For example, the heating pattern 2730 may be constantan with a temperature coefficient of resistance of 0.000008, which converges to zero, and the bridge 2650 may be nickel with a temperature coefficient of resistance of 0.006 or copper with a temperature coefficient of resistance of 0.00386.

[0283] The materials of the heating pattern 2730 and the connecting pattern 2263 of the bridge 2650 are not limited to these. The lower the temperature coefficient of resistance, the higher the efficiency of heat transfer and the less loss of available power. Also, the lower the temperature coefficient of resistance, the faster the temperature rise of the heating element when power is applied.

[0284] The connecting pattern 2650 may have low thermal conductivity. The bridge 2650 is made of a material with lower thermal conductivity than that of the heater assembly 2630. The connecting pattern 2650 is made of a material with lower thermal conductivity than that of the heating pattern 2730 of the heater assembly 2630. The amount of heat generated by the connecting pattern 2650 is less than that of the heating pattern 2730.

[0285] The interconnect pattern 2650 is covered with a layer having thermal insulating properties.

[0286] This reduces the amount of heat generated by the heater assembly 2630 that is conducted to the first substrate 2621 via the bridge 2650, preventing the first substrate 2621 from overheating and breaking down. It also prevents other parts other than the heater assembly 2630 from becoming hot.

[0287] Another embodiment of the aerosol generating unit will now be described.

[0288] In the following, an embodiment of the aerosol generating unit 200 will be described, which is a heater for heating the stick containing the aerosol product, which is inserted inside the stick and heats according to the induction heating type.

[0289] FIG. 18 is a diagram showing a part of an embodiment of an aerosol generating unit 200 that is inserted into the inside of a stick and that implements an induction heating method.

[0290] Referring to this figure, heater 2950 is inserted into hollow 2814 of heater pin 2810. Heater 2950 is formed long in the vertical direction. Heater 2950 is a magnetic material and generates heat by induced current. Heater 2950 has the shape of a wound thin plate.

[0291] The sensor 2850 is inserted into the hollow 2814. The sensor 2850 is disposed below the heater 2950. The sensor 2850 senses the temperature of the heater 2950. The sensor lead wires 2859 are connected to the sensor 2850. The sensor lead wires 2859 are provided in pairs. The sensor lead wires 2859 transmit power supplied from a power supply to the sensor 2850. The sensor lead wires 2859 transmit a control signal to the sensor 2850.

[0292] Reinforcement member 2840 is inserted into hollow 2814 of heater pin 2810. Reinforcement member 2840 is placed below sensor 2850. Reinforcement member 2840 supports the lower part of sensor 2850. Reinforcement member 2840 is fixed in close contact with the inner circumferential surface of heater pin 2810 in hollow 2814. Reinforcement member 2840 fills hollow 2814. Sensor lead wire 2859 passes through reinforcing member 2840 and is exposed to the outside of heater pin 2810.

[0293] FIG. 19 is a diagram showing a part of a heater in an embodiment of the aerosol generating unit.

[0294] Referring to this figure, heater 2950 is formed to be long in the vertical direction. Heater 2950 is cylindrical. Heater 2950 is flexible. Heater 2950 has a shape in which a thin plate is rolled or folded into a cylindrical shape. The folding direction BD in which heater 2950 is folded intersects with the length direction LD of heater 2950. For example, the folding direction BD of heater 2950 is perpendicular to the length direction LD of heater 2950.

[0295] Referring to (a) of this figure, heater 2950 is bent in the bending direction BD. One side of heater 2950 is cut along the length direction LD of heater 2950. Heater 2950 has a cylindrical side with a cut gap 2853 extending long in the length direction LD. Heater 2950 has a C-shaped cross section. Heater hole 2954 is defined as a space formed inside heater 2950. Heater 2950 surrounds the sides of heater hole 2954. Heater hole 2954 extends long from the inside of heater 2950 upward and downward. Heater hole 2954 communicates with cut gap 2853. Heater hole 2954 is open at the top and bottom.

[0296] Referring to (b) of this figure, in another example, heater 2950 is a cylindrical heater rolled in the circumferential direction. Heater 2950 has a helical cross section. In this case, heater holes 2954 are also formed inside heater 2950. In this case, there is also a cut gap 2853 on one side that extends long in the length direction LD.

[0297] The heater 2950 in the second state 2952 has a smaller curvature than the heater 2950 in the first state 2951. The heater 2950 in the second state 2952 has a larger radius of curvature than the heater in the first state 2951. The heater 2950 in the second state 2952 has larger heater holes 2954 and larger incision gaps 2853 than the heater in the first state 2951.

[0298] The heater 2950 is formed of an elastic body. The heater 2950 has a property of restoring itself from a first state 2951 in which it is wound up to a second state 2952 in which it is opened outward by elastic force. The heater 2950 has a restoring force or elastic force in a direction in which the curvature decreases. The heater 2950 has a restoring force or elastic force in a direction in which the radius of curvature of the heater 2950 increases. The heater 2950 has a restoring force or elastic force in a direction in which the size of the heater hole 2954 and the incision gap 2853 increases.

[0299] FIG. 20 is a diagram showing a heater in an embodiment of the aerosol generating unit.

[0300] Referring to this figure, heater 2950 in first state 2951 is inserted into hollow 2814 of heater pin 2810. Diameter D1 of the outer periphery of heater 2950 in first state 2951 is smaller than diameter D3 of hollow 2814. Diameter D2 of the outer periphery of heater 2950 in second state 2952 is larger than diameter D3 of hollow 2814.

[0301] Within hollow 2814, heater 2950 has an elastic force or restoring force that moves from first state 2951 to second state 2952. Within hollow 2814, diameter D1 of the outer circumferential surface of heater 2950 is the same as diameter D2 of hollow 2814. Within hollow 2814, the curvature of the outer circumferential surface of heater 2950 is the same as the curvature of hollow 2814. Within hollow 2814, heater 2950 uses its elastic force to push out the inner circumferential surface of heater pin 2810, applying pressure to the inner circumferential surface of heater pin 2810.

[0302] As a result, the outer peripheral surface of heater 2950 is tightly attached and fixed to the inner peripheral surface of heater pin 2810 within hollow 2814. Furthermore, the manufacturing process is simplified because there is no need for bonding to fix heater 2950 inside heater pin 2810 and no lead wire is required for heater 2950. Furthermore, problems such as twisting or breakage of the lead wire can be avoided.

[0303] The heater 2950 shown in this figure is inserted into the heater pin 2810. When inserting the heater 2950 into the heater pin 2810, the heater 2950 is bent into a first position 2951. In this case, the heater 2950 in the first position 2951 is inserted into the hollow 2814 of the heater pin 2810 through an opening. The heater 2950 is inserted into the hollow 2814 in the bent state into the first position 2951. When inserting the heater 2950 into the heater pin 2810, the heater 2950 presses against the inner circumferential surface of the heater pin 2810 in the hollow 2814, making tight contact and being fixed inside the heater pin 2810. When the heater 2850 is inserted into the heater pin 2810, the heater 2950 is positioned higher than the cover portion 2851.

[0304] FIG. 21 is a diagram showing a heater including an induction coil as an example of the aerosol generating unit.

[0305] Referring to this figure, the passage of the pipe 208 is formed cylindrically. The passage of the pipe 208 wraps around the pin body 2811 and the pin tip 2812 on the sides.

[0306] Induction coil 2860 is wound multiple times around the outer periphery of pipe 2821. Induction coil 2860 surrounds heater 2950. Heater 2950 generates heat via induction coil 2860 by induction heating.

[0307] The hollow 2814 communicates with the cover hole 2958. The heater 2950 extends vertically. The heater 2950 is inserted into and fixed in the hollow 2814 through the cover hole 254. The heater 2950 is in close contact with the inner circumferential surface of the pin body 2811 in the hollow 2814. The heater 2950 is disposed above the bottom of the insertion space 2824. The heater 2950 is disposed above the first cover portion 2931. The heater 2950 is disposed above the first flange 2901. The first line L1-L1' is defined as an imaginary line that is flush with the bottom of the insertion space 2824 or the upper surface of the first cover portion 2931. The second line L2-L2' is defined as an imaginary line that is flush with the bottom of the heater 2950 and aligned with the first line L1-L1'. The second line L2-L2' is spaced upward from the first line L1-L1' by a predetermined distance d, which is equal to or greater than 0 mm.

[0308] This reduces the effect of heat generated from the heater 2950 on the first cover part 2931. In addition, it prevents the first cover part 2931 from being thermally deformed, which would cause a gap between the heater pin 2810 or widen the gap, thereby preventing leakage of liquid or other physical substances through the gap.

[0309] FIG. 22 is a diagram showing a heater including an induction coil as an example of the aerosol generating unit.

[0310] Referring to this figure, sensor 2850 is inserted into heater hole 2954. Sensor 2850 has a shape corresponding to heater hole 2954. Sensor 2850 is formed to be long in both the vertical direction. For example, sensor 2850 has a long, elongated cylindrical shape. Sensor 2850 is surrounded by heater 2950. Sensor 2850 is inside heater 2950 and senses the temperature of heater 2950.

[0311] The sensor lead wire 2859 extends from the sensor 2850 to the underside of the heater 2950. The sensor lead wire 2859 passes through the stiffener 2840 and extends to the underside of the second cover portion 2932.

[0312] The reinforcing member 2840 overlaps the upper surface of the first flange 2901. The reinforcing member 2840 extends vertically. The upper end of the reinforcing member 2840 is located above the upper surface of the first flange 2901. The lower end of the reinforcing member 2840 is located below the upper surface of the first flange 2901. The reinforcing member 2840 is located inside the upper surface of the first flange 2901, and reinforces the rigidity of the pin body 2811 around the upper surface of the first flange 2901.

[0313] This reduces the effect of heat generated from the heater 2950 on the first cover portion 2931. In addition, it is possible to prevent the first cover portion 2931 from being thermally deformed, which would cause a gap between the heater pin 2810 to form or widen, thereby preventing foreign matter such as liquid from leaking into the gap.

[0314] Additionally, the stiffener 2840 can prevent the heater pin 2810 from bending around the first flange 2901 .

[0315] The aerosol generating unit 200 according to one aspect of the present invention includes a pipe 208 that provides an insertion space 2824, covers 2931, 2932 that close one side of the insertion space 2824 and form a bottom, a heater pin 2810 that extends long, one side of which is fixed to the covers 2931, 2932 and the other side of which is disposed in the insertion space 2824, and that provides a hollow 2814 that extends long inside, and a heater 300 that is inserted into the hollow 2814 and is disposed longer than the covers 2931, 2932.

[0316] According to another aspect of the present disclosure, the heater 2850 further includes an induction coil 2860 surrounding the pipe 208 around the heater pin 2810 to generate heat.

[0317] Below, we will describe another embodiment of an aerosol generating unit, which is a heater for heating a stick containing an aerosol product, which is inserted inside the stick and heats according to the induction heating type.

[0318] FIG. 23 is a diagram showing another embodiment of the aerosol generating unit 200 that is inserted into the inside of a stick and that implements an induction heating method.

[0319] The embodiment of the aerosol generating unit includes a heater 3010 and a heater body 3011. The heater body 3011 extends long in the vertical direction. The heater body 3011 is cylindrical.

[0320] The heater 3010 has a heater tip 3012. The heater tip 3012 is formed at one end of the heater 3010. The heater tip 3012 is connected to the heater body 3011 at the upper side of the heater body 3011. The heater tip 3012 has a shape that narrows toward the upper side. The heater tip 3012 has a sharp end. A cigarette or a stick is inserted into the heater 3010.

[0321] An example of an aerosol generating unit includes covers 3020, 3030 having a chamber formed therein.

[0322] For ease of explanation, the structure in which the heater 3010, the first cover 3020 and the second cover 3030 are combined will be referred to as a heater assembly HA.

[0323] The covers 3020 and 3030 are opened to form a heater insertion hole through which the heater 3010 passes. The chamber C includes a first cover 3020 surrounding a first space on one side thereof, and a second cover 3030 coupled to the first cover 3020 and surrounding a second space on the other side thereof.

[0324] The first cover 3020 includes a first plate 3021 having a heater insertion hole formed therein. The second cover 3030 includes a second plate 3031 supporting the other end of the heater 3010, and extends from the second plate 3031 to be in close contact with the inner circumferential surface of the pipe 3041.

[0325] The first plate 3021 covers the upper side of the second peripheral portion 3032. The first plate 3021 is in close contact with the upper side of the second peripheral portion 3032. The first plate 3021 covers the upper side of the chamber C.

[0326] The second peripheral portion 3032 has an open inlet hole 3324 , is in close contact with the inner circumferential surface of the pipe 3041 , and is connected to a sealing member (not shown) inside the chamber C through the inlet hole 3324 .

[0327] The pipe 3041 is in close contact with the inner circumferential surface of the pipe 3041, and the pipe 3041 is integrally connected to the sealing member 3134 inside the chamber C through the inlet hole 3324.

[0328] The first cover 3020 is disposed on or coupled to the top of the second cover 3030 .

[0329] The hooks 3222 are inserted into the hook holes 3322 and hook onto the second peripheral edge 3032. The hooks 3222 can restrict the first cover 3020 from being separated upward from the second cover 3030. The first cover 3020 protrudes to support the sides of the heater 3010.

[0330] The first positioning protrusion 3035 is spaced inward from the edge of the second plate 3031 to form a spaced apart portion 3315. The second positioning protrusion 3036 is spaced inward from the edge of the second plate 3031 to form a spaced apart portion 3315.

[0331] When the first positioning protrusion 3035 and the second positioning protrusion 3036 are inserted into a mold, the separation portion 3315 can ensure a tolerance margin and ensure stability in manufacturing.

[0332] The positioning pin 3313 protrudes downward from the lower part of the second plate 3031. There are multiple positioning pins 3313. The positioning pin 3313 is cylindrical with rounded ends.

[0333] The hook 3222 is inserted into the hook hole 3322 to fasten the first cover 3020 and the second cover 3030 together.

[0334] When the first cover 3020 and the second cover 3030 are joined, a flange (not shown) is disposed inside the chamber C.

[0335] The first lead wire 3161 and the second lead wire 3162 are exposed on the underside of the second plate 3031 .

[0336] The heater 3010 is electrically coupled to the first lead wire 3161 and is supplied with power.

[0337] The second plate 3031 does not have to cover the lower side of the inlet hole 3324. The inlet hole 3324 is open downward. The second plate 3031 is recessed radially inward with the inlet hole 3324 spaced radially inward from the lower part of the inlet hole 3324. The lower part of the second peripheral portion 3032 located between the inlet holes 3324 is called a recess 3321. The recess 3321 is exposed downward as the edge of the second plate 3031 is recessed radially inward.

[0338] 24 and 25 are cross-sectional views from different sides showing an example of an aerosol generating unit in which a heater assembly is included.

[0339] Referring to these figures, the first cover 3020 is placed or coupled to the top of the second cover 3030. The hooks 3222 are inserted into the hook holes 3322 and hook onto the second rim 3032. The hooks 3222 restrict the first cover 3020 from being disengaged upward from the second cover 3030.

[0340] The first plate 3021 covers the upper side of the second peripheral portion 3032. The first plate 3021 is in close contact with the upper side of the second peripheral portion 3032. The first plate 3021 covers the upper side of the chamber C. The first plate 3021 is hooked onto the upper side of the second peripheral portion 3032, and the first peripheral portion 3022 is inserted into the second space 3034. The first peripheral portion 3022 is disposed inside the second peripheral portion 3032. The outer peripheral surface of the second peripheral portion 3022 is surrounded by the second peripheral portion 3032. The lower portion of the first peripheral portion 3022 is spaced upward from the second plate 3031.

[0341] The heater body 3011 passes through an insertion opening (not shown) of the first plate 3021 and is press-fitted into the first plate 3021. The flange 3013 is disposed in the first space 3224.

[0342] The first space 3224 is located below the first plate 3021, and the first plate 3021 covers the upper side of the first space 3224. The inner peripheral surface 223 of the first peripheral portion 3022 surrounds the sides of the first space 3224. The first space 3224 is open downward.

[0343] The support guide 3226 is formed by sloping the lower end of the support bar 3225. The support guide 3226 slopes upward from the lower end of the support bar 3225 toward the first space 3224.

[0344] The first positioning protrusion 3035 is spaced inward from the edge of the second plate 3031 to form a spaced apart portion 3315. The second positioning protrusion 3036 is spaced inward from the edge of the second plate 3031 to form a spaced apart portion 3315.

[0345] The flange 3013 is supported or fixed by the support bar 3225. The flange 3013 is spaced from the first peripheral edge portion 3022 by the support bar 3225. The flange 3013 is spaced from the first peripheral edge portion 3022 and the first plate 3021 to form a gap in the first space 3224. The flange 3013 is spaced upward from the second plate 3031. The lower end portion 3151 and the fixing portion 3152 of the heater 3010 are supported or fixed by the first plate 3031.

[0346] The sensor 3016 senses the temperature of the heater 3010. The sensor 3016 is provided inside the heater 3010. The heater 3010 is hollow, and the sensor 3016 is inserted into the heater 3010. The sensor 3016 is formed to be long in one direction and is arranged along the longitudinal direction of the heater body 3011. The sensor 3016 is electrically connected to the second lead wire 3162 and power is supplied to the sensor 3016. The heater 3010 is electrically connected to the first lead wire 3161 and power is supplied to the sensor 3016.

[0347] This allows the first cover 3020 and the second cover 3030 to be stably coupled to each other, forming a chamber C therein. Furthermore, movement of the heater 3010 is prevented or minimized within the covers 3020 and 3030 of the chamber C, and the heater 3010 is arranged long toward the upper side. Furthermore, this prevents the first lead wire 3161 and the second lead wire 3162 from contacting each other, being twisted with each other, or being broken.

[0348] The port portion 3213 protrudes downward from the first plate 3021 around the heater insertion opening 3214. The port portion 3213 surrounds the periphery of the lower end of the heater insertion opening 3214. The port portion 3213 is formed to be inclined upward toward the heater insertion opening 3214.

[0349] 26 and 27 are cross-sectional views from different sides showing an example of an aerosol generating unit in which a heater assembly is included.

[0350] Referring to these figures, the pipe 3041 is cylindrical. The pipe 3041 has an insertion space 3044 therein, which is open on both sides. The insertion space 3044 is cylindrical. The insertion space 3044 is formed long in the vertical direction.

[0351] The upper side of the insertion space 3044 is connected to the outside. The pipe 3041 is connected to the heater assembly HA. The heater assembly HA closes the lower part of the pipe 3041. The first plate 3021 is disposed between the insertion space 3044 and the first space 3224. The first plate 3021 separates the insertion space 3044 and the first space 3224.

[0352] The pipe 3041 may be integrally formed and connected to the sealing member 3134 in the heater assembly HA. The pipe 3041 and the sealing member 3134 are integrally connected to each other via the inlet hole 3324.

[0353] The pipe 3041 and the sealing member 3134 are integrally connected to each other via a hook hole 3322 .

[0354] The flange 3013 is fixed within the sealing member 3134. When the heater 3010 passes through the heater insertion opening 3214, the flange 3013 comes into contact with and slides against the support guide 3226 and the second support bar 3227, and is guided into the first space 3224. The first support bar 3225 and the second support bar 3227 support the sides of the flange 3013 that are disposed in the first space 3224.

[0355] The heater body 3011 and the heater tip 3012 are disposed in the insertion space 3044. A cigarette is inserted into the insertion space 3044, and the bottom is penetrated by the heater 3010. The heater 3010 generates heat to heat the cigarette. The first lead wire 3161 and the second lead wire 3162 are exposed at the bottom of the pipe 3041.

[0356] The locking claws 3415 may be formed integrally with the pipe 3041. The locking claws 3415 protrude radially inward from the inner circumferential surface of the pipe 3041. The locking claws 3415 cover and support the upper edge of the first plate 3021. The locking claws 3415 extend in the circumferential direction along the upper edge of the first plate 3021. The locking claws 3415 restrict the heater assembly HA from moving upward.

[0357] The pipe bottom 3411 is formed at the lower part of the pipe 3041. The pipe bottom 3411 covers the recess 3321 (see FIG. 6). The pipe bottom 3411 contacts the recess 3321 and supports the lower part of the second cover 3030. The pipe bottom 3411 restricts the heater assembly HA from moving downward.

[0358] This allows the gaps between the components of the heater assembly HA to be completely filled, and also the gaps between the housing 3040 and the heater assembly HA to be completely filled.

[0359] Furthermore, foreign matter such as liquid can be prevented from leaking into the gap around the heater 3010.

[0360] In addition, the heater assembly HA is stably fixed or supported in the housing 3040. In addition, the positions of the first lead wire 3161 and the second lead wire 3162 can be prevented from being twisted or broken relative to each other.

[0361] In addition, the assembling process of the heater assembly HA can be further simplified, and the process of connecting the heater assembly HA and the housing 3040 can be further simplified.

[0362] Hereinafter, an embodiment of a mobile communication terminal combined with an aerosol generating unit will be described based on a detailed embodiment of a heater.

[0363] The aerosol generator disclosed herein may be coupled to a mobile communication terminal in various ways, and the layout and shape of components of the mobile communication terminal may be changed depending on the coupling method.

[0364] Here, as described above, an example will be described in which an aerosol generating unit having a cylindrical pipe-shaped attachment portion is coupled to a mobile communication terminal. A cigarette or stick-shaped aerosol product is inserted into the pipe-shaped attachment portion. The cigarette inserted into the attachment body is heated by various heating methods, such as the heater or heating portion described above.

[0365] The above-described embodiment includes a case where the antennas of the aerosol generating unit 200 and the communication unit 400 are coupled to each other depending on the position of the aerosol generating unit in the mobile communication terminal.

[0366] For convenience, an example in which the antennas of the aerosol generation unit 200 and the communication unit 400 are coupled is referred to as a coupled module 4100.

[0367] FIG. 28 is a diagram showing a part of the aerosol generating unit 200 and the communication unit 400 combined together as an embodiment of the mobile communication terminal.

[0368] The mobile communication terminal does not necessarily require a combination module, and the aerosol generation unit 200 and the communication unit 400 may exist separately without the combination module 4100 depending on the location of the aerosol generation unit 200. Conversely, when the aerosol generation unit 200 is located near the communication unit 400, they may be provided as a single combination module 4100. In the embodiment shown here, the antennas of the aerosol generation unit 200 and the communication unit 400 are combined, as will be described in detail below.

[0373] The medium 4240 is a liquid or granular solid that emits volatile compounds capable of forming an aerosol when thermal energy is applied. The medium 4240 is configured to contain volatile flavor compounds including tobacco (plant material) and nicotine. The medium 4240 can be composed of a plurality of granules, the size of which is 0.4 mm to 112 mm.

[0374] A cooling unit 4230 is provided between the filter 4220 and the medium 4240, and the cooling unit 4230 is provided in a hollow cylindrical shape. In addition, to prevent the medium 4240 from being discharged from the article body 4210 or into the cooling unit 4230, a first cover 4241 is provided on the bottom surface of the article body 4210, and a second cover 4242 is provided between the medium 4240 and the cooling unit 4230.

[0375] The first cover 4241 and the second cover 4242 are made of a porous material that allows air to move but prevents the medium 4240 from escaping, and the article body 4210 is made of paper or the like that surrounds the first cover 4241, the medium 4240, the second cover 4242, the cooling part 4230, and the filter 4220.

[0376] 28 and 29, the mounting part 4110 is provided with a mounting body 4111 having an accommodating space 4112 for the medium 4240. The mounting body 4111 is cylindrical with the accommodating space 4112 formed therein, and is made of a dielectric material.

[0377] The dielectric material is a thermoplastic resin such as polyester resin, cellulose resin, polycarbonate resin, acrylic resin, styrene resin, polyolefin resin, vinyl chloride resin, amide resin, imide resin, polyethersulfone resin, sulfone resin, polyetheretherketone resin, polyphenylene sulfide resin, vinyl alcohol resin, vinylidene chloride resin, vinyl butyral resin, arylate resin, polyoxymethylene resin, epoxy resin, etc. The mounting portion 4110 may be made of any one or a combination of two or more of the above-mentioned materials.

[0378] The upper surface 4113 of the mounting body is provided with an insertion port 4116 for the article body 4210 to enter and exit, the antenna 4130 is fixed to the circumferential surface 4114 of the mounting body, and a heating unit wire 4126 for controlling the heating unit 4120 is fixed to the bottom surface 4115 of the mounting body.

[0379] The heating unit 4120 may be provided as an internal heating type heat source that supplies heat energy from inside the article body 4210, or may be provided as an external heating type heat source that supplies heat energy from outside the article body 4210.

[0380] FIG. 29 shows an example of an internal heating method, and the heating unit 4120 according to this embodiment includes a coil 4121 that inductively heats a conductor 4250 (such as a metal plate) located inside the medium 4240 .

[0381] In this case, the coil 4121 is provided inside the mounting body 4111 and is provided to surround the accommodating space 4112. That is, the coil 4121 is wound along the height direction (Y-axis direction) of the mounting body and is provided to surround the accommodating space 4112.

[0382] The coil 4121 is supplied with power via a heater wire 4126, and FIG. 29 shows an example in which the heater wire 4126 passes through the bottom surface 4115 of the mounting body and is connected to the coil 4121.

[0383] When current is supplied to the coil 4121 via the heating wire 4126, the conductor 4250 located inside the medium 4240 is heated, and when the user inhales outside air through the filter 4220, the aerosol generated from the medium 4240 is supplied to the user through the filter 4220.

[0384] FIG. 30 shows another embodiment of a coupling module according to the present invention.

[0385] Figure 30(a) shows another embodiment of an internal heating type heating unit, and the heating unit 4120 in this embodiment is provided with a heater 4123 that penetrates the article body 4210 and contacts the medium 4240 when the article body 4210 is inserted into the accommodating space 4112.

[0386] The heater 4123 according to this embodiment is made of a bar- or plate-shaped metal that is fixed to the bottom surface 4115 of the mounting body and positioned inside the receiving space 4112. In this case, when the article body 4210 is inserted into the receiving space 4112, the free end of the heater 4123 penetrates the first cover 4241 (the bottom surface of the article body) and is positioned inside the medium 4240.

[0387] Figures 30(b) and 30(c) show examples of indirect heating type heating units. The heating units in Figures 30(b) and 30(c) are similar in that they include a pipe-shaped heater 4124 that surrounds the circumferential surface of the article body 4210 inserted into the storage space 4112. The pipe-shaped heater 4124 is fixed to the mounting body 4111 so as to be located inside the storage space 4112.

[0388] On the other hand, the heater 4124 in Figure 30(b) is distinguished from the heater 4124 in Figure 30(c) in that it receives power via the heating wire 4126, but generates heat via a coil 125 located inside the mounting body 4111.

[0389] As in the above-described embodiment, the antenna 4130 is configured to include a patch 4131 (first patch) fixed to the mounting body 4111 and positioned outside the receiving space 4112, and a ground 4132 (first ground) fixed to the mounting body 4111 and positioned outside the receiving space 4112. The patch 4131 and the ground 4132 are made of a conductor such as a metal plate and need to be fixed to the mounting body 4111 so as to be positioned at points separated from each other.

[0390] The antenna 4130 is supplied with current through a feed line 4134 (first feed line) connected to the patch 4131 and an antenna wire 4133 connecting the feed line 4134 to the communication unit 400. The feeding refers to the operation of applying current to the patch 4131.

[0391] The patch 4131 and the ground 4132 may be arranged in various ways to set the radiation direction of the antenna 4130. That is, when the mounting body 4111 is provided in a cylindrical shape, the patch 4131 and the ground 4132 may be arranged to be spaced apart along the circumferential direction of the mounting body 4111, or along the height direction (Y-axis direction) of the mounting body 4111.

[0392] Meanwhile, unlike the illustrations, the mounting body 4111 may be provided in a prismatic shape. In this case, the patch 4131 and the ground 4132 may be arranged to be spaced apart along the circumferential direction of the mounting body 4111 (see FIG. 28) or along the height direction of the mounting body 4111 (see FIG. 31).

[0393] The shape of the patch 4131, the size and thickness of the patch 4131, the distance between the patch 4131 and the ground 4132, the material and thickness of the mounting body 4111 which is a dielectric, etc. must be set according to the frequency band desired for transmission and reception.

[0394] When the mounting body 4111 is provided in a cylindrical or prismatic shape, the patch 4131 and the ground 4132 fixed to the outer circumferential surface of the mounting body 4111 are curved.

[0395] As shown in Figure 29(b), the patch 4131 and ground 4132 are curved to fit the cross-sectional shape of the mounting body 4111, and such a shape of the patch and ground can sometimes improve the efficiency of transmission and reception (depending on the set transmission and reception frequency band).

[0396] The communication and aerosol generating unit 100 having the above-described structure can be provided in a communication terminal having a communication unit and a power supply unit, thereby realizing wireless communication function and aerosol generating function.

[0397] In order to ensure compatibility with communication terminals, the combination module 4100 has a heating unit connector 4127 on the heating unit wire 4126 that can be detachably connected to a circuit (such as a board) of the communication terminal, and an antenna connector 4135 (first antenna connector) on the antenna wire 4133 that can be detachably connected to a circuit (such as a board) of the communication terminal.

[0398] Meanwhile, the combination module 4100 further includes a control board 4160 for controlling the operation of the heating unit 4120 and a communication unit 400 for controlling wireless communication through the antenna 4130 .

[0399] The control board 4160 is provided as a device for controlling the power supplied to the coils 4121, 4125 and heaters 4123, 4124 via the heating unit wire 4126, and the communication unit 300 (communication module or communication circuit) is provided as a device for realizing wireless communication functions suitable for the application of the communication terminal to which the combination module 4100 is attached.

[0400] In order to ensure compatibility with the communication and aerosol generating unit 100 equipped with the control board 4160 and the communication unit 400, the connection module 4100 further includes a PCB 4140 to which the control unit and the communication unit are fixed.

[0401] The PCB 4140 is provided with a first connector 4141 to which the heating unit connector 4127 is connected, a second connector 4142 to which the antenna connector 4135 is connected, and a third connector 4143 to which a control unit of a communication terminal (such as a terminal control unit or an application processor) is connected.

[0402] Therefore, an embodiment of the present invention can provide a combined module 4100 of a communication unit and an aerosol generator that can embody both a wireless communication function and an aerosol generation function and is applicable to various communication terminals.

[0403] FIG. 32 shows yet another embodiment of a coupling module 4100. In FIG.

[0404] The coupling module 4100 according to this embodiment is distinguished from the previous embodiments in that it further includes an extension body 4117 extending from the mounting body 4111 .

[0405] The extension body 4117 is formed as a plate protruding in the radial direction (X-axis direction) of the mounting body from the circumferential surface of the mounting body 4111. The extension body 4117 is made of a dielectric material, and may be made of the same dielectric material as the mounting body 4111 or a different dielectric material from the mounting body 4111.

[0406] When the extension body 4117 is provided, the feed line 4134 provided in the patch 4131 is provided in the extension body 4117. The antenna wire 4133 is connected to the feed line 4134 by bonding, and in this case, the extension body 4117 serves as a means for improving the durability of the coupling module 4100 by maintaining a stable connection between the antenna wire 4133 and the feed line 4134.

[0407] Figure 32(a) shows that the patch 4131 and the ground 4132 are arranged so as to be spaced apart along the circumferential surface of the mounting body 4111, and Figure 32(b) shows that the patch 4131 and the ground 4132 are arranged so as to be spaced apart along the height direction (Y-axis direction) of the mounting body 4111.

[0408] On the other hand, as shown in FIG. 32(c), the patch 4131 may be fixed to the circumferential surface of the mounting body 4111, the power supply line 4134 may be fixed to the upper surface of the extension body 4117, and the ground 4132 may be fixed to the lower surface of the extension body 4117 (the surface opposite to the surface to which the power supply line is fixed).

[0409] If necessary to set the radiation direction of the antenna 4130, the coupling module 4100 of Fig. 32(c) may be configured so that the ground 4132 is fixed to the same plane as the plane on which the feed line 4134 is located (see dotted line). Also, unlike Fig. 32(c), the patch 4131 may be fixed to the extension body 4117, and the ground 4132 may be fixed to the mounting body 4111.

[0410] FIG. 33 shows another embodiment of the coupling module 4100, in which the patch 4131 and the ground 4132 are located on the extension body 4117.

[0411] 33(a), the patch 4131 and the ground 4132 are fixed to the extension body 4117 so as to be spaced apart along the height direction (Y-axis direction) of the mounting body. The patch 4131 and the ground 4132 are provided on the same plane provided by the extension body 4117, but FIG. 33 shows that the patch and ground are fixed to the upper surface of the extension body 4117.

[0412] Unlike FIG. 33(a), the patch 4131 and the ground 4132 may be fixed to the extension body 4117 so as to be spaced apart along the radial direction (for example, the Z-axis or X-axis direction) of the mounting body.

[0413] FIG. 33( b ) shows an embodiment in which one of the patch 4131 and the ground 4132 is fixed to the upper surface of the extension body 4117 , and the other of the patch and the ground is fixed to the lower surface of the extension body 4117 .

[0414] In the communication and aerosol generation unit 100 having the above-described structure, when the item 4200 is inserted into the storage space 4112, the dielectric constant of the mounting portion 4110 changes, and therefore the possibility cannot be ruled out that the function set for the antenna 4130 may be reduced.

[0415] To solve the above-mentioned problem, the combining module 4100 further includes a second antenna 4170 .

[0416] FIG. 34 is a diagram showing another embodiment of a combined module in which the antenna of the communication unit and the aerosol generation unit are combined.

[0417] 34, the combination module 4100 according to this embodiment also includes a mounting portion 4110, a heating portion 4120, and a first antenna 4130. The structures of the mounting portion 4110, the heating portion 4120, and the first antenna 4130 are similar to those of the previous embodiment, and therefore detailed descriptions thereof will be omitted.

[0418] The second antenna 4170 is configured to include a dielectric body 4171 made of a dielectric and located at a position separated from the mounting portion 4110, a second patch 4172 made of a conductor and fixed to the dielectric body 4171, and a second ground 4173 made of a conductor, fixed to the dielectric body 4171, and located at a position separated from the second patch 4172.

[0419] The material of the dielectric body 4171 may be the same as or different from the material of the mounting body 4111. The second patch 4172 and the second ground 4173 may be located on the same plane provided by the dielectric body 4171 or may be fixed to the dielectric body 4171 so as to face each other, and Fig. 34 shows the latter case.

[0420] The combination module 4100 according to this embodiment includes a PCB 4140 having a circuit for switching between the first antenna 4130 and the second antenna 4170, a control board 4160 provided on the PCB and controlling the operation of the heating unit 4120, and a communication unit 400 shown in FIG. 1 that supplies current to the antennas 4130 and 4170.

[0421] The second patch 4172 is provided with a second feed line 4174, which is connected to the communication unit 400 via a second antenna wire 4175. To this end, the PCB is provided with a fourth connector 4144, and the second antenna wire 4175 is provided with a second antenna connector that is fastened to the fourth connector 4144.

[0422] FIG. 35 is a diagram showing another embodiment of a combined module in which the antenna of the communication unit and the aerosol generation unit are combined.

[0423] As shown in Figure 35(a), the PCB 4140 is provided with a first circuit 4154 that connects the communication unit 400 and the first antenna 4130, a second circuit 4156 that connects the communication unit 400 and the second antenna 4170, and a switch 4153 that controls the opening and closing of the two circuits 4154, 4156.

[0424] The structures of the circuits 4154, 4156 and the switch 4153 can be embodied in various ways, but FIG. 35(a) shows that one circuit (communication unit circuit 4151) in which the first circuit 4154 and the second circuit 4156 are connected to the communication unit 400 is branched off from the switch 4153.

[0425] The communication unit circuit 4151 is equipped with an amplifier 4152 (Low Noise Amplifier or Linear Power Amplifier), and for impedance matching, the first circuit 4154 is equipped with a first matching network 155, and the second circuit 4156 is equipped with a second matching network 157.

[0426] Figure 35(b) shows yet another embodiment, which is distinguishable from the embodiment of Figure 35(a) in that the first circuit 4154 includes a first amplifier 4158 and a first matching network 4155, and the second circuit 4156 includes a second amplifier 4159 and a second matching network 4157.

[0427] 35(a) and 35(b), in which the communication unit and the aerosol generation unit are combined, when the aerosol product 4200 is not inserted into the storage space 4112, the switch 4153 closes the first circuit 4154 (connecting the communication unit to the first antenna) and opens the second circuit 4156 (disconnecting the communication unit to the second antenna). However, when the item 4200 is inserted into the storage space 4112, the switch 4153 closes the second circuit 4156 (connecting the communication unit to the second antenna) and opens the first circuit 4154 (disconnecting the communication unit to the first antenna).

[0428] Therefore, in one embodiment, by making it possible to select an antenna that performs wireless communication function from among multiple antennas depending on whether or not the aerosol generation function is being executed, it is possible to minimize the degradation of wireless communication function due to changes in the dielectric constant of the mounting portion 4110.

[0429] The combination module 4100 of the communication unit and the aerosol generator is provided in a mobile communication terminal. In this case, the antennas 4130 and 4170 provided in the combination module 4100 are connected to the communication unit 400 via the antenna wires 4133 and 4175, and the heater 4120 of the combination module 4100 is connected to the control unit 100 via the heater wire 4126.

[0430] The combination module 4100 including the communication unit 400 and the control board 4160 may be included in a mobile communication terminal.

[0431] In the mobile communication terminal according to this embodiment, the communication unit 400 and the control board 4160 are mounted on a PCB 4140. In this case, the communication unit 400 and the control board 4160 are configured to be connected to the control unit 100 via a third connector 4143 of the PCB.

[0432] The above-described communication and aerosol generating unit, and the structure and control method of a communication terminal equipped with the module are merely examples of the present invention.

[0433] The above describes the manner in which the aerosol-generating unit heats the aerosol product or the cigarette containing the aerosol product, and the heating methods are divided into internal heating and external heating depending on whether the heating is inside or outside the aerosol product or the cigarette.

[0434] ` In the case of external heating, the cigarette is heated by induction heating or a patterned film-type capsule, while in the case of internal heating, a needle is inserted into the cigarette to heat it directly, or the needle acts as a susceptor to heat the cigarette.

[0435] Hereinafter, an embodiment will be described in which, when an aerosol generating unit is located in a mobile communication terminal using the above-described heating method, the temperature of the aerosol generating unit is sensed and the system is precisely controlled accordingly.

[0436] When controlling the temperature of the heating section of the aerosol generating section, a temperature sensor can be directly attached to the inside or outside of the aerosol generating section to measure and sense the temperature. In this case, there is a possibility that the temperature sensor may be damaged. To prevent this, a non-contact temperature sensor may be positioned outside the heating section, but in this case, there is a possibility that power efficiency may be reduced.

[0437] Hereinafter, an embodiment will be described in which the temperature of the aerosol generating unit of a mobile communication terminal is accurately measured without damaging the sensor.

[0438] FIG. 36 is a simplified diagram showing an embodiment of the aerosol generating unit for ease of explanation.

[0439] The aerosol generating unit 5100 of the mobile communication terminal generates aerosol by heating the cigarette accommodated in the aerosol generating unit 5100 using an induction heating method. The induction heating method refers to a method of applying an alternating magnetic field, the direction of which is periodically changed, to a magnetic material that generates heat due to an external magnetic field, thereby generating heat from the magnetic material.

[0440] When an alternating magnetic field is applied to a magnetic material, energy loss occurs in the magnetic material due to eddy current loss and hysteresis loss, and the lost energy is released from the magnetic material as heat energy. The greater the amplitude or frequency of the alternating magnetic field applied to the magnetic material, the more heat energy is released from the magnetic material.

[0441] The aerosol generating unit 5100 applies an alternating magnetic field to the magnetic material, causing the magnetic material to emit thermal energy, and transfers the thermal energy emitted from the magnetic material to the cigarette.

[0442] The magnetic material that generates heat due to an external magnetic field may be a susceptor 5110. The susceptor 5110 is formed in the shape of a piece, a thin piece, a strip, or the like.

[0443] The susceptor 5110 includes a metal or carbon. The susceptor 5110 includes at least one of ferrite, a ferromagnetic alloy, stainless steel, and aluminum (Al).

[0444] The susceptor 5110 may also include at least one of graphite, molybdenum, silicon carbide, niobium, nickel alloy, metal film, ceramic such as zirconia, transition metal such as nickel (Ni) or cobalt (Co), and metalloid such as boron (B) or phosphorus (P).

[0445] The aerosol generating unit 5100 includes a storage space 5120 for storing cigarettes. The storage space 5120 includes an opening that opens from the outside of the storage space 5120 so as to store the cigarettes in the aerosol generating unit 5100. The cigarettes are stored in the aerosol generating unit 5100 through the opening of the storage space 5120 in a direction from the outside of the storage space 5120 toward the inside of the storage space 5120.

[0446] 36(a), a susceptor 5110 is disposed at the inner end of the accommodating space 5120. The susceptor 5110 is attached to the bottom surface formed at the inner end of the accommodating space 5120. A cigarette is inserted into the susceptor 5110 from the upper end thereof and is accommodated in the accommodating space 5120 up to the bottom surface thereof.

[0447] 36(b), the aerosol generating unit 5100 may not include the susceptor 5110. In this case, the susceptor 5110 is included in the cigarette.

[0448] The aerosol generating unit 5100 applies an alternating magnetic field to the susceptor 5110 and includes a coil unit 5130 whose resonance frequency varies in response to a temperature change of the susceptor 5110 due to induction heating of the susceptor 5110. The coil unit 5130 includes at least one coil.

[0449] The coil is embodied as a solenoid. The coil may be a solenoid wound along the side of the receiving space 5120, and the cigarette 5200 is received in the internal space of the solenoid. The material of the conductor constituting the solenoid is copper (Cu).

[0450] However, the material of the conductor that makes up the solenoid is not limited to this, and can be any material that has a low resistance value and allows a high current to flow, such as silver (Ag), gold (Au), aluminum (Al), tungsten (W), zinc (Zn), and nickel (Ni), or an alloy containing at least one of these.

[0451] The coil unit 5130 is wound along the outer surface of the receiving space 5120 and is disposed at a position corresponding to the susceptor 5110. The arrangement of the coil of the coil unit 5130 will be described in detail below.

[0452] The aerosol generating unit 5100 supplies power to the coil unit 5130 from a power supply unit of the mobile communication terminal.

[0453] The power supply may be, but is not limited to, a lithium iron phosphate (LiFePO4) battery. For example, the battery may be a lithium cobalt oxide (LiCoO2) battery, a lithium titanate battery, etc.

[0454] The control unit controls the power supplied to the coil unit 5130. When the coil unit 5130 includes a plurality of coils, the control unit can vary the driving frequency of the coils.

[0455] The control unit controls the driving frequency to inductively heat the susceptor 5110. In addition, the control unit senses the resonance frequency of the coil that is changed by the induction heating of the susceptor 5110, and calculates the temperature of the susceptor based on the sensed resonance frequency.

[0456] Hereinafter, an embodiment in which the control unit senses the resonant frequency will be described in detail.

[0457] FIG. 37 is a diagram showing an example of an aerosol product or cigarette that can be coupled to the aerosol generating unit of a mobile communication terminal.

[0458] The cigarette 5200 includes a tobacco rod 5210 and a filter rod 5220. While Figure 37 shows the filter rod 5220 constructed as a single section, the filter rod 5220 is not limited to this and may be constructed from multiple segments.

[0459] For example, the filter rod 5220 includes a first segment that cools the aerosol and a second segment that filters out certain components contained in the aerosol.

[0460] Additionally, the filter rod 5220 may further include at least one segment that performs other functions.

[0461] The cigarette 5200 is wrapped in at least one wrapper 5240. The wrapper 5240 has at least one hole formed therein through which external air can enter or internal air can escape.

[0462] As an example, the cigarette 5200 is wrapped in one wrapper 5240 .

[0463] As another example, the cigarette 5200 is wrapped in two or more overlapping wrappers 240. Specifically, a first wrapper wraps the tobacco rod 5210, and a second wrapper wraps the filter rod 5220. The tobacco rod 5210 and the filter rod 5220 wrapped in each wrapper are joined together, and the entire cigarette 5200 is rewrapped in a third wrapper.

[0464] The tobacco rod 5210 includes an aerosol-forming material, such as, but 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 5210 may also include other additives, such as flavoring agents, humectants, and / or organic acids.

[0465] A flavoring liquid such as menthol or a moisturizer may be added to the tobacco rod 5210 by spraying it onto the tobacco rod 5210.

[0466] The tobacco rod 5210 can be produced in various ways. For example, the tobacco rod 5210 can be produced in a sheet or strand. Alternatively, the tobacco rod 5210 can be produced as shredded tobacco, which is a tobacco sheet cut into small pieces.

[0467] As shown in Figure 37(b), the cigarette 5200 further includes a susceptor 5110. In this case, the susceptor 5110 is disposed on the tobacco rod 5210, as shown in Figure 37(b). The susceptor 5110 extends from the end of the tobacco rod 5210 toward the filter rod 5220.

[0468] The tobacco rod 5210 is surrounded by a thermally conductive material. For example, the thermally conductive material may be, but is not limited to, a metal foil such as aluminum foil. The thermally conductive material surrounding the tobacco rod 5210 can evenly distribute heat transferred to the tobacco rod 5210 and improve the thermal conductivity applied to the tobacco rod 5210, thereby improving the flavor of the aerosol generated from the tobacco rod 5210.

[0469] The filter rod 5220 may be a cellulose acetate filter. The filter rod 5220 may be formed in a variety of shapes. For example, the filter rod 5220 may be a cylindrical rod, a tubular rod with a hollow interior, or a recessed rod with a cavity interior.

[0470] When the filter rod 5220 is made up of multiple segments, the multiple segments can be made with different shapes.

[0471] The filter rod 5220 is fabricated so that flavor is released from the filter rod 5220.

[0472] For example, a scented liquid is sprayed onto the filter rod 5220, and another fiber onto which the scented liquid is applied is inserted into the filter rod 5220.

[0473] The filter rod 5220 includes at least one capsule 5230. The capsule 5230 generates a flavor and may also generate an aerosol. For example, the capsule 5230 may be formed by a structure in which a liquid containing a flavoring agent is enclosed in a coating.

[0474] The capsule 5230 may be, but is not limited to, a spherical or cylindrical shape.

[0475] When the filter rod 5220 includes a cooling segment for cooling the aerosol, the cooling segment is made of a polymeric or biodegradable polymeric material. For example, the cooling segment is made of pure polylactic acid.

[0476] Alternatively, the cooling segment may be made of a cellulose acetate filter containing a plurality of perforations. However, the cooling segment may be made of any structure and material that cools the aerosol.

[0477] FIG. 38 is a diagram showing an example in which a cigarette is inserted into an aerosol generating unit of a mobile communication terminal.

[0478] FIG. 38( a ) shows an example of a cigarette 5200 inserted into the aerosol generating unit 5100 when the susceptor 5110 is disposed in the aerosol generating unit.

[0479] FIG. 38( b ) shows an example of a cigarette 5200 inserted into the aerosol generating unit 5100 when the susceptor 5110 is placed on the cigarette 5200 .

[0480] 38(a), the cigarette 5200 is accommodated in the accommodation space along the length direction of the cigarette 5200. The susceptor 5110 is inserted into the cigarette 5200 accommodated in the aerosol generating unit 5100.

[0481] When the cigarette 5200 is inserted into the susceptor 5110, the tobacco rod 5210 comes into contact with the susceptor 5110. The susceptor 5110 has a structure that extends in the length direction of the aerosol-generating unit 5100 so as to be inserted into the cigarette 5200.

[0482] The susceptor 5110 is located in the center of the receiving space 5120 so as to be inserted into the center of the cigarette 5200 .

[0483] 38(a), the susceptor 5110 is, but is not limited to, a single unit. In other words, the aerosol-generating unit of the present invention may include multiple susceptors 5110 that extend in the length direction of the aerosol-generating unit and are arranged parallel to each other so as to be inserted into the cigarette 5200.

[0484] The coil unit 5130 includes at least one coil, which is wound along the outer surface of the receiving space 5120 and extends in the longitudinal direction. The coil extending in the longitudinal direction is disposed on the outer surface of the receiving space 5120. The coil extends in the longitudinal direction to a length corresponding to the susceptor 5110 and is disposed at a position corresponding to the susceptor 5110.

[0485] 38(b), the cigarette 5200 is accommodated in the accommodation space 5120 along the length direction of the cigarette 5200. When the cigarette 5200 is inserted into the accommodation space 5120, the susceptor 5110 is surrounded by the coil portion 5130.

[0486] For uniform heat transfer, the susceptor 5110 is located at the center of the tobacco rod 5210. In Fig. 38(b), the susceptor 5110 is a single unit, but the present invention is not limited to this.

[0487] In other words, the aerosol-generating portion 5100 of the present invention may include a plurality of susceptors 5110 contained within the cigarette 5200 .

[0488] The coil portion 5130 includes at least one coil, which is wound along the outer surface of the receiving space 5120 and extends in the longitudinal direction. The coil extending in the longitudinal direction is disposed on the outer surface of the receiving space 5120. The coil extends in the longitudinal direction to a length corresponding to the susceptor 5110 and is disposed at a position corresponding to the susceptor 5110.

[0489] FIG. 39 is a diagram showing an example of a method for winding a coil in an aerosol generating unit.

[0490] FIG. 39(a) shows a method of winding a coil when the coil portion 5130 includes only one coil, and FIGS. 39(b) and (c) show a method of winding a coil when the coil portion 5130 includes multiple coils.

[0491] Figure 39 shows that a cigarette containing a susceptor 5110 is contained in a storage space within the aerosol generating unit 5100, but the following embodiment also applies when the susceptor 5110 is needle-shaped and fixedly positioned in the aerosol generating unit 5100.

[0492] 39(a), (b), and (c), the inner surface of the accommodating space 5120 refers to the area that abuts the area where the cigarette 5200 is inserted, and the outer surface of the accommodating space 5120 refers to the opposite side of the inner surface. The length direction of the aerosol-generating portion refers to the direction perpendicular to the end surface of the accommodating space where the cigarette 5200 is inserted.

[0493] 39(a), the coil portion 5130 includes a first coil 5131. The first coil 5131 surrounds the outer surface of the accommodation space.

[0494] The first coil 5131 is wound along the length direction of the aerosol generating part 5100 from the outer surface of the accommodation space.

[0495] The first coil 5131 is wound along the length direction from the outer surface of the accommodation space so as to correspond to the susceptor 5110.

[0496] On the other hand, in FIG. 39(a), the aerosol generation part 5100 includes only one coil, and therefore the first coil 5131 is also referred to as the coil 5131.

[0497] As shown in FIG. 39(a), when the aerosol generating unit 5100 uses only one coil 5131 to inductively heat the susceptor 5110 and measure the temperature of the susceptor 5110, there is an advantage in that the manufacturing convenience is increased.

[0498] 39(b), the coil portion 5130 further includes a second coil 5132. The first coil 5131 and the second coil 5132 are wound alternately along the length direction from the outer surface of the accommodation space.

[0499] 39(c), the coil portion 5130 further includes a second coil 5132. The first coil 5131 is wound in a first region 5171 on the outer surface of the accommodating space 5120, and the second coil 5132 is wound in a second region 5172 different from the first region.

[0500] As shown in Figures 39(b) and (c), when the aerosol generation unit 5100 includes multiple coils 5131, 5132, the aerosol generation unit 5100 continuously heats the susceptor 5110 via the first coil 5131 while measuring the temperature of the susceptor 5110 in real time via the second coil 5132.

[0501] An embodiment capable of measuring the temperature of the susceptor 5110 in real time will be described in detail below.

[0502] FIG. 40 is a flowchart for explaining an example of measuring the temperature of the heating unit of the aerosol generating unit.

[0503] In the above-described embodiment of the aerosol generating unit, the temperature of the heating unit can be measured as follows.

[0504] In step S910, when power is supplied to the aerosol generating unit or the insertion of a cigarette is detected in the aerosol generating unit, the control unit of the mobile communication terminal causes the aerosol generating unit to drive the first coil 5131 within a first frequency range.

[0505] For example, when driving the first coil 5131 within a first frequency range, the current applied to the first coil 5131 is greatest at the first resonant frequency.

[0506] That is, the current changes depending on the drive frequency applied to the coil, and the control unit controls the aerosol generating unit using information about the frequency response characteristics. Hereinafter, a detailed description will be given with reference to a diagram showing the relationship between the frequency applied to the coil and the frequency response characteristics.

[0507] In step S920, the control unit detects a change in the resonant frequency of the second coil based on the second frequency range.

[0508] When the temperature of the susceptor changes, the frequency response of the second coil is varied from the first frequency response to a second frequency response.

[0509] In response to a change in temperature of the susceptor, the controller senses a second resonant frequency of the second coil within a second frequency range.

[0510] The control unit detects a change in the resonant frequency due to a temperature change of the susceptor in the aerosol generating unit using a sensor in the aerosol generating unit or an NFC antenna of the mobile communication terminal.

[0511] The NFC antenna includes a loop antenna module including a loop coil, and the loop antenna module of the NFC antenna of the mobile communication terminal according to the embodiment detects a frequency corresponding to a temperature change of a susceptor heated by magnetic induction.

[0512] Hereinafter, a detailed description will be given with reference to a diagram showing the relationship between the resonant frequency and response characteristics due to temperature changes of the susceptor.

[0513] In step S930, the control unit calculates the temperature of the susceptor based on the change in the resonant frequency of the second coil.

[0514] When the temperature of the susceptor changes, the control unit calculates the temperature of the susceptor using the difference in frequency response characteristics.

[0515] The control unit detects the difference in frequency using a frequency detection sensor in the aerosol generating unit or an NFC antenna of the mobile communication terminal, and calculates the temperature of the susceptor based on the difference.

[0516] When a difference occurs in the frequency characteristics due to the temperature of the susceptor heated by magnetic induction in the aerosol generating unit, the loop antenna coil of the NFC antenna receives the frequency response characteristics and provides information about the response characteristics to the control unit.

[0517] As a result, the control unit varies the drive frequency applied to the aerosol generation coil to control the temperature of the susceptor of the aerosol generation unit.

[0518] The specific logic by which the control unit calculates the temperature of the susceptor in accordance with the frequency response characteristics of the coil will be described in detail below with reference to figures relating to the difference in resonant frequency and the change in frequency response characteristics.

[0519] FIG. 41 is a diagram showing the relationship between the drive frequency applied to the coil and the frequency response characteristics.

[0520] In FIG. 41, the horizontal axis represents frequency, and the vertical axis represents the intensity of the frequency signal.

[0521] The current applied to the first coil 5131 varies according to the first drive frequency for driving the first coil 5131 .

[0522] Assuming that the frequency response characteristic of the first coil 5131 is maximized at the first resonant frequency f01, the current applied to the first coil 5131 is maximized at the first resonant frequency fo1.

[0523] The first resonant frequency fo1 is determined by the first coil 5131 and a first capacitor coupled in series to the first coil 5131.

[0524] Furthermore, the response characteristics of the first coil 5131 decrease as the frequency increases, with the first resonance frequency fo1 as a reference.

[0525] For example, the magnitude h1 of the response characteristic of the first coil 5131 at a first frequency f1 that is greater than the first resonant frequency fo1 is greater than the magnitude h2 of the response characteristic of the first coil 5131 at a second frequency f2 that is greater than the first frequency f1.

[0526] The control unit controls the current applied to the first coil 5131 by varying the first drive frequency within a preset first frequency range.

[0527] When the current applied to the first coil 5131 is variable, the temperature of the susceptor 5110 provided in the aerosol generating unit also varies.

[0528] The aerosol product may be a cigarette as described above. For example, the control unit sets the first drive frequency to the first resonant frequency fo1, thereby supplying maximum power to the first coil 5131. This heats the susceptor 5110 to a maximum temperature.

[0529] As another example, the control unit supplies the first coil 5131 with a first power that is smaller than the maximum power by setting the first drive frequency to a first frequency f1 that is larger than the first resonance frequency fo1.

[0530] This causes the temperature of the susceptor 5110 to be heated to a first temperature that is lower than the maximum temperature.

[0531] As another example, the control unit sets the first drive frequency to a second frequency f2 that is greater than the first frequency f1, thereby supplying a second power that is less than the first power to the first coil 5131. As a result, the temperature of the susceptor 5110 is heated to a second temperature that is less than the first temperature.

[0532] FIG. 42 is a diagram showing the relationship between the change in resonant frequency due to the temperature change of the susceptor and the response characteristics.

[0533] Specifically, frequency responses 1111, 1112, 1113 of the second coil 5132 due to temperature changes of the susceptor 5110 are shown.

[0534] When the susceptor 5110 is at a first temperature, the response characteristic of the second coil 5132 is maximized at a second resonant frequency fo2, which is determined by the second coil 5132 and a second capacitor coupled in series with the second coil 5132.

[0535] Furthermore, the second resonant frequency fo2 of the second coil 5132 increases as shown by Fo2'' or decreases as shown by Fo2' as the temperature of the susceptor 5110 increases.

[0536] As the second resonant frequency fo2 is varied, the frequency at which the maximum current is output also changes. The control unit 5150 sweeps the second drive frequency of the second coil 5132 within the second frequency range, and obtains information indicating the second resonant frequency fo2 of the second coil 5132 based on the result of the frequency sweep.

[0537] For example, the control unit 5150 sweeps the second drive frequency of the second coil within the second frequency range and determines the drive frequency at which the current applied to the second coil 5132 is maximum as the second resonant frequency.

[0538] On the other hand, when the second frequency range overlaps with the first frequency range, the susceptor 5110 is inductively heated by the second coil 5132. The heating by the second coil 5132 is unexpected, which may cause inaccurate temperature control of the susceptor 5110. Therefore, the second resonant frequency fo2 is set lower than the first resonant frequency fo1.

[0539] The second frequency range may be set to be different from the first frequency range. For example, the lower limit of the first frequency range may be set to be greater than the upper limit of the second frequency range. As another example, from the lower limit of the first frequency range, the susceptor 5110 is heated to a first heating temperature, and from the upper limit of the second frequency range, the susceptor 5110 is heated to a second heating temperature lower than the first heating temperature. The second heating temperature is a temperature at which no aerosol is generated.

[0540] Furthermore, if the upper limit of the second frequency range affects the temperature change of the susceptor 5110, the temperature of the susceptor 5110 may change even during the frequency sweep of the second coil 5132. Therefore, the upper limit of the second frequency range is set to a frequency that does not affect the temperature change of the susceptor 5110. For example, if the first frequency range is 2 MHz to 4 MHz, the second frequency range is set to 0.1 MHz to 0.3 MHz, but is not limited to this.

[0541] FIG. 43 is a diagram showing the relationship between the difference in resonant frequency and the change in frequency response characteristics.

[0542] 43 shows frequency responses 1210, 1220 of the second coil 5132 due to changes in the temperature of the susceptor 5110. As the temperature of the susceptor 5110 changes, the frequency response of the second coil 5132 changes from a first frequency response 1210 to a second frequency response 1220.

[0543] After heating of the susceptor 5110 begins, the control unit calculates the temperature of the susceptor 5110 based on the frequency difference fo2d between the third resonant frequency fo2a of the second coil sensed at a first point in time and the fourth resonant frequency fo2b at a second point in time a predetermined time after the first point in time.

[0544] The control unit calculates the temperature of the susceptor 5110 based on matching data between the resonance frequency difference fo2d and the temperature of the susceptor 5110. The matching data between the resonance frequency difference fo2d and the temperature of the susceptor 5110 may be already stored in the memory in the storage unit 800 as a lookup table.

[0545] FIG. 44 is a flowchart illustrating another example of the operation method of the aerosol generating unit, and a diagram showing the control cycle thereof.

[0546] FIG. 44(a) shows another example of the operation method of the aerosol generation unit, in which the aerosol generation unit 200 heats the susceptor 5110 with only one coil and calculates the temperature of the susceptor 5110.

[0547] FIG. 44(b) shows the control cycle of the flowchart shown in FIG. 44(a).

[0548] The control unit 100 controls the coil of the aerosol generating unit at a preset control period. Each control period includes a heating period and a sensing period. The control unit 100 heats the aerosol product or the susceptor 5110 via the coil of the aerosol generating unit in the heating period, and calculates the temperature of the susceptor 5110 via the coil in the sensing period.

[0549] Specifically, in step S1310, the control unit 100 drives the coil of the aerosol generating unit based on the first frequency range in the heating section.

[0550] The method for driving the coil of the aerosol generating unit in the heating section is the same as the method described above. The control unit 100 controls the current applied to the coil of the aerosol generating unit by varying the driving frequency within a preset frequency range. When the current applied to the coil of the aerosol generating unit is varied, the temperature of the aerosol product or the susceptor 5110 also varies.

[0551] In step S1320, the control unit 100 senses a change in the resonant frequency of the coil of the aerosol generating unit based on the second frequency range in the sensing section.

[0552] The method of detecting the change in the resonant frequency of the coil 5131 in the detection section is the same as the detection method described above. The control unit 100 sweeps the drive frequency of the coil of the aerosol generation unit within the second frequency range, and detects the resonant frequency of the coil of the aerosol generation unit based on the result of the frequency sweep.

[0553] For example, the control unit 100 sweeps the drive frequency of the coil of the aerosol generation unit within the second frequency range, and determines the drive frequency when the current applied to the coil of the aerosol generation unit is at its maximum as the resonant frequency.

[0554] In this embodiment, the first frequency range and the second frequency range are set to be the same because the control unit heats the susceptor 5110 using only one coil in the aerosol generation unit and calculates the temperature of the susceptor 5110. For example, the first frequency range and the second frequency range are set to 2 MHz to 4 MHz, but are not limited to this.

[0555] Meanwhile, the size of the heating section is set to be larger than the size of the sensing section. When the size of the heating section is larger than the size of the sensing section, the controller can minimize the temperature change of the susceptor 5110 and accurately measure the temperature of the susceptor 5110.

[0556] In step S1330, the control unit 100 calculates the temperature of the susceptor 5110 based on the change in the resonance frequency of the coil of the aerosol generating unit.

[0557] The method for calculating the temperature of the susceptor 5110 in the sensing section is the same as in the case of the two coil sets described above.

[0558] The control unit 100 calculates the temperature of the susceptor 5110 based on the frequency difference between the fifth resonant frequency of the coil 5131 sensed at a first point in time after the sensing period begins and the sixth resonant frequency at a second point in time a predetermined time after the first point in time.

[0559] The control unit 100 calculates the temperature of the susceptor 5110 based on matching data between the resonant frequency difference and the temperature of the susceptor 5110. The matching data between the resonant frequency difference and the temperature of the susceptor 5110 may be already stored in the storage unit 800 as a lookup table.

[0560] FIG. 45 is a block diagram showing an example of a mobile communication terminal capable of easily controlling the temperature and system of an aerosol generating unit.

[0561] Referring to FIG. 45, the mobile communication terminal according to the embodiment includes a control unit 100, an aerosol generating unit 200, a power supply unit 300, and a memory unit 800.

[0562] Although not shown in FIG. 45, the susceptor may be included in the aerosol-generating unit 200 or in a cigarette coupled to the aerosol-generating unit 200 .

[0563] The power supply unit 300 supplies power to the internal components of the aerosol generating unit 200. The power supply unit 300 provides DC power, and a power converter (not shown) of the aerosol generating unit 200 converts the DC power provided by the power supply unit 300 into AC power and transmits it to the aerosol generating unit 200, and the aerosol generating unit 200 heats the susceptor by magnetic induction using the AC power.

[0564] The heating section of the aerosol-generation section 200 includes at least one coil. In one embodiment, the heating section of the aerosol-generation section 200 includes a first coil.

[0565] In another embodiment, the heating section of the aerosol generation section 200 includes a first coil 5131 and a second coil 5132 .

[0566] The heating unit of the aerosol generating unit 200 may further include a capacitor connected in series or parallel to the coil. In one embodiment, the heating unit of the aerosol generating unit 200 includes a first capacitor connected in series or parallel to the first coil.

[0567] In another embodiment, the heating unit of the aerosol generating unit 200 includes a first capacitor connected in series or parallel to a first coil and a second capacitor connected in series or parallel to a second coil. Although only the case where the capacitors are connected in series to the coils will be described below, the following description also applies to the case where the capacitors are connected in parallel to the coils.

[0568] The control unit 100 controls the driving frequency of the heating unit of the aerosol generation unit 200. In the series resonant circuit, the current flowing through the first coil and / or the second coil (if there is a second coil) is maximized at the resonant frequency. By controlling the driving frequency of the heating unit of the aerosol generation unit 200, the control unit 100 heats the susceptor of the aerosol generation unit 200 and obtains information regarding the temperature detection of the susceptor using a frequency detection sensor.

[0569] The frequency detection sensor may utilize an NFC antenna in the communication unit 400 or may include a detection sensor in the aerosol generation unit 200.

[0570] The control unit 100 obtains information about a change in the resonance frequency due to a change in the temperature of the susceptor in the aerosol generating unit 200 using a frequency detection sensor such as an NFC antenna of the communication unit 400.

[0571] The control unit 100 heats the susceptor via the first coil and obtains information corresponding to the temperature change of the susceptor by an NFC antenna or another frequency sensor based on the change in the resonant frequency of the second coil, or the control unit 110 heats the susceptor using only one of the first coils and obtains information on the change in the resonant frequency corresponding to the susceptor temperature by an NFC antenna or another frequency sensor.

[0572] The memory unit 800 stores matching data between the resonant frequency and the susceptor temperature or matching data between the change in the resonant frequency and the susceptor temperature in the form of a lookup table, and the control unit 100 calculates the susceptor temperature based on the lookup table stored in the memory unit 800.

[0573] In addition, the control unit 100 can stably control the entire system including the PID (Proportional-Integral-Differential) control of the mobile communication terminal including the aerosol generating unit 200 based on the calculated temperature.

[0574] An example in which the control unit 100 controls the first coil and the second coil, or controls the temperature using only the first coil 5131, has been described in detail above.

[0575] Hereinafter, another embodiment will be described in which the temperature of a susceptor in an aerosol generating unit of a mobile communication terminal can be sensed and controlled by the system of the mobile communication terminal.

[0576] In this embodiment, the alternating current supplied to the coil portion is controlled to heat the susceptor.

[0577] Alternatively, in another embodiment, the AC current supplied to the first coil is controlled to heat the susceptor, and then the DC current supplied to the first coil is controlled to induce a change in the magnetism of the susceptor, thereby calculating the temperature of the susceptor.

[0578] In another embodiment, the AC current supplied to the first coil is controlled to heat the susceptor, and then the DC current supplied to the second coil is controlled to induce a change in the magnetism of the susceptor, thereby calculating the temperature of the susceptor.

[0579] The mobile communication terminal detects the change in magnetism in the coil using a magnetic force sensing unit of the aerosol generating unit or a magnetic sensor of a sensing unit within the mobile communication terminal.

[0580] The controller of the mobile communication terminal calculates the temperature of the susceptor based on the detected change in magnetism, and controls the system accordingly, as will be described in detail below.

[0581] FIG. 46 is a diagram showing an example of a method for winding a coil in an aerosol generating unit.

[0582] Figure 46 shows that a cigarette containing a susceptor 5110 is placed in a storage space within the aerosol generating unit 5100, but the following embodiments also apply when the susceptor 5110 is fixed and positioned in the aerosol generating unit 5100 in a needle-like or similar form.

[0583] FIG. 46(a) shows a method of winding a coil when the coil portion 5130 includes only one coil, and FIGS. 46(b) and (c) show a method of winding a coil when the coil portion 5130 includes multiple coils.

[0584] The magnetic force sensing unit senses a change in the magnetic force of the susceptor.

[0585] Here, the magnetic force sensing unit may be separately provided in the aerosol generating unit, or may be a magnetic sensor in a sensing unit in the mobile communication terminal or a magnetic sensor in a camera module.

[0586] For the sake of convenience, this embodiment shows that the magnetic force sensing unit is located within the aerosol generating unit. However, the same embodiment is also applicable when using a magnetic sensor of a sensing unit of a mobile communication terminal or a magnetic sensor of a camera module in an input unit, and is defined as a magnetic force sensing unit here.

[0587] The magnetic force sensing unit includes at least one Hall sensor, and the control unit measures the temperature of the susceptor based on the change in magnetic force sensed by the magnetic force sensing unit.

[0588] The Hall sensor measures the magnitude of the magnetic field due to the voltage (Hall voltage) generated by the current in the orthogonal coil and the magnetic field. Therefore, when the magnetic force sensor measures the change in magnetism caused by magnetic induction in the aerosol generator, the controller receives and controls the corresponding susceptor temperature information.

[0589] In FIG. 46(a), the coil part 5131 includes a coil wound along the length direction of the aerosol generation part 5100 from the outer surface of the accommodation space.

[0590] The control unit controls the AC current to the coil unit 5131 to heat the susceptor 5110 and induce a change in magnetism.

[0591] As another example, the control unit heats the susceptor 5110 by controlling the alternating current supplied to the coil unit 5131, and induces magnetism in the susceptor 5110 by controlling the direct current supplied to the coil unit 5131.

[0592] The magnetic force sensor senses the magnetism induced in the susceptor 5110 and transmits the information to the controller, which then calculates and controls the temperature of the susceptor 5110 based on the changed magnetism.

[0593] In FIG. 46(b), the coil portion 5130 includes a first coil 5131 and a second coil 5132 wound alternately along the length direction from the outer surface of the accommodation space.

[0594] In Figure 46(c), the coil portion 5130 includes a first coil 5131 wound in a first region 5171 on the outer surface of the storage space 5120, and a second coil 5132 wound in a second region 5172 different from the first region.

[0595] In this case, the control unit heats the susceptor 5110 by controlling the AC current supplied to the first coil 5131, and induces magnetism in the susceptor 5110 by controlling the DC current supplied to the second coil 5132.

[0596] The magnetic force sensor senses the magnetism induced in the susceptor 5110 and transmits the information to the controller, which then calculates and controls the temperature of the susceptor 5110 based on the changed magnetism.

[0597] FIG. 47 is a diagram showing the change in magnetic force and output voltage due to the change in temperature of the susceptor.

[0598] Figure 47(a) shows magnetic force change 5291 due to temperature change of the susceptor. The horizontal axis represents temperature, and the vertical axis represents magnetic force. As shown in Figure 47(a), the magnetic force decreases as the temperature of the susceptor increases. The memory unit 800 of the mobile communication terminal stores data indicating magnetic force change due to temperature change of the susceptor in the form of a lookup table.

[0599] This allows the relationship between the temperature change of the susceptor and the change in magnetic force to be determined. When the magnetic force sensor detects a change in the magnetic force of the susceptor, it outputs an output value corresponding to the magnetic force of the susceptor. The output value is set to a voltage, current, frequency, or the like.

[0600] 47(b) shows the relationship between the magnetic force value of the susceptor and the output voltage 5301. That is, the horizontal axis represents the magnitude of the magnetic force change, and the vertical axis represents the output voltage. It can be seen that the larger the magnetic force change value of the susceptor, the larger the output voltage. Therefore, the memory unit 800 of the mobile communication terminal stores the output values ​​according to the magnetic force change in a lookup table, and when the control unit receives the output value of the magnetic force sensing unit, the corresponding magnetic force change value of the susceptor is obtained based on the lookup table stored in the memory unit, thereby obtaining the temperature information of the susceptor.

[0601] Based on this, the control unit controls the temperature of the susceptor.

[0602] FIG. 48 is a diagram showing an example of controlling the temperature of a susceptor by a coil of an aerosol generating unit of a mobile communication terminal.

[0603] A flowchart illustrating an example of a method for sensing the temperature of the susceptor 5110 based on a change in the magnetic force of the susceptor 5110 when the susceptor 5110 is formed of a permanent magnet is shown.

[0604] When the susceptor 5110 is formed of a permanent magnet, there is no need to induce magnetism in the susceptor 5110. In other words, the first coil 5131 of the aerosol generation unit is used only for heating the susceptor 5110.

[0605] Therefore, for convenience of explanation, the first coil 5131 will be referred to as coil 5131.

[0606] In step S1110, the control unit 100 inductively heats the susceptor 5110. The susceptor 5110 is provided in the aerosol product or the aerosol generating unit 200. The aerosol product is the aforementioned cigarette, and the susceptor 5110 is formed of a permanent magnet.

[0607] The control unit 100 controls the alternating current supplied to the coil 5131. When an alternating current is supplied to the coil 5131, the direction of the magnetic field formed inside the coil 5131 is periodically changed. When the susceptor 5110 is exposed to the alternating magnetic field formed by the coil 5131, the susceptor 5110 is induction heated.

[0608] The control unit 100 controls the temperature of the susceptor 5110 by varying the amplitude, frequency, etc. of the alternating current supplied to the coil 5131 in accordance with a preset temperature profile.

[0609] In step S1120, the magnetic force sensing unit senses a change in magnetic force due to a change in temperature of the susceptor 5110.

[0610] In one embodiment, the magnetic force sensor outputs a magnetic force value corresponding to the temperature value of the susceptor 5110 as information in the form of a voltage or the like.

[0611] In step S1130, the control unit 100 calculates the temperature of the susceptor 5110 based on the magnetic force change information output by the magnetic force sensing unit, or obtains stored temperature information.

[0612] For example, the control unit 100 obtains the temperature of the susceptor 5110 corresponding to the output value output by the magnetic force sensor from the lookup table stored in the storage unit 800.

[0613] As another example, the control unit 100 obtains the magnetic force difference between a first magnetic force value of the susceptor 5110 sensed at a first time point after starting heating and a second magnetic force value at a second time point a predetermined time after the first time point.

[0614] Furthermore, the control unit 100 obtains the temperature of the susceptor 5110 corresponding to the magnetic force value difference from the lookup table stored in the storage unit 800.

[0615] 48, when the susceptor 5110 is a permanent magnet, the susceptor 5110 itself has magnetism. Therefore, the control unit 100 does not need to induce magnetism in the susceptor 5110.

[0616] In this case, the aerosol generating unit 200 of the mobile communication terminal has a simple design, and the control unit 100 of the mobile communication terminal can easily control the temperature of the aerosol generating unit 200.

[0617] Meanwhile, in an embodiment in which the susceptor 5110 is limited to a permanent magnet, many design constraints may arise due to the electrical or mechanical properties of the permanent magnet. Therefore, even if the susceptor 5110 of the aerosol generation unit 200 of the present invention is not a permanent magnet, the temperature of the susceptor 5110 can be measured by inducing magnetism in the susceptor 5110.

[0618] Below, an embodiment will be described showing how to measure the temperature of the susceptor 5110 when the susceptor 5110 is not a permanent magnet.

[0619] FIG. 49 is a diagram showing the relationship between the control period and the interval for controlling the susceptor of the aerosol generating unit.

[0620] The control unit 100 controls the coil unit 5130 in a preset control cycle. Each control cycle includes a first section in which the susceptor 5110 is heated and a second section in which magnetism is induced in the susceptor 5110.

[0621] The control unit 100 heats the susceptor 5110 in the first section, and calculates the temperature of the susceptor 5110 in the second section.

[0622] The control unit 100 inductively heats the susceptor 5110 using only the first coil 5131, thereby inducing magnetism in the susceptor 5110. Alternatively, the control unit 100 heats the susceptor 5110 via the first coil 5131, and induces magnetism in the susceptor 5110 via the second coil 5132.

[0623] A method in which the control unit 100 measures the temperature of the susceptor 5110 using only the first coil 5131, and a method in which the control unit 100 measures the temperature of the susceptor 5110 using the first coil 5131 and the second coil 5132 will be described in detail below.

[0624] FIG. 50 is a diagram showing an example of controlling a susceptor when the coil part of the aerosol generating part is formed by one coil part.

[0625] 50, in step S1310, the control unit 100 inductively heats the susceptor 5110 through the coil 5131 in the first section. The method of inductively heating the susceptor 5110 through the coil 5131 in the first section is the same as the induction heating method described above. That is, the control unit 100 controls the AC current supplied to the coil 5131 in the first section.

[0626] When an alternating current is supplied to the coil 5131, the direction of the magnetic field formed inside the coil 5131 is changed periodically. When the susceptor 5110 is exposed to the alternating magnetic field formed by the coil 5131, the susceptor 5110 is inductively heated.

[0627] In this case, the susceptor 110 is provided in the aerosol generating unit 200 or a cigarette, which is an aerosol product.

[0628] The control unit 100 controls the temperature of the susceptor 5110 by varying the amplitude, frequency, etc. of the alternating current supplied to the coil 5131 in accordance with a preset temperature profile.

[0629] In step S1320, the control unit 100 induces magnetism in the susceptor 5110 via the coil 5131 in the second section.

[0630] The control unit 100 controls the DC current supplied to the coil 5131 in the second section. When the DC current is supplied to the coil 5131, a magnetic field is formed outside the coil 5131. When the susceptor 5110 is exposed to the magnetic field, a magnetic moment reacts inside the susceptor 5110, and the susceptor 5110 is magnetized.

[0631] In step S1330, the magnetic force sensing unit senses a change in magnetic force due to a change in temperature of the susceptor 5110 in the second section.

[0632] In the second section, the magnetic force sensing method of the susceptor 5110 is the same as the magnetic force sensing method described above, that is, the magnetic force sensing unit outputs a magnetic force value corresponding to the temperature value of the susceptor 5110 in the form of a voltage.

[0633] On the other hand, the size of the first section is set to be larger than the size of the second section, in which case the temperature change of the susceptor 5110 can be minimized and the temperature of the susceptor 5110 can be measured accurately.

[0634] In step S1340, the control unit 100 calculates the temperature of the susceptor 5110 based on the change in magnetic force.

[0635] In the second interval, the control unit 100 calculates the temperature in the same manner as described above. In other words, the control unit 100 obtains the temperature of the susceptor 5110 corresponding to the output value output by the magnetic force sensor from the lookup table stored in the storage unit 800. As another example, the control unit 100 obtains a magnetic force difference between a first magnetic force value of the susceptor 5110 detected at a first time point after the start of heating and a second magnetic force value detected at a second time point after a predetermined time has elapsed from the first time point.

[0636] Furthermore, the control unit 100 may obtain the temperature of the susceptor 5110 corresponding to the magnetic force value difference from a lookup table stored in the storage unit 800.

[0637] FIG. 51 is a diagram showing an example of controlling a susceptor when the coil part of the aerosol generating part is formed of two or more coil parts.

[0638] This embodiment is a flowchart for explaining a method for measuring the temperature of the susceptor 5110 via the first coil 5131 and the second coil 5132.

[0639] In step S1410, the control unit 100 inductively heats the susceptor 5110 in the first section via the first coil 5131. The method of inductively heating the susceptor 5110 in the first section via the first coil 5131 has been described above. That is, the control unit 100 controls the AC current supplied to the first coil 5131 in the first section.

[0640] When an alternating current is supplied to the first coil 5131, the direction of the magnetic field formed inside the first coil 5131 is changed periodically. When the susceptor 5110 is exposed to the alternating magnetic field formed by the first coil 5131, the susceptor 5110 is inductively heated. In this case, the susceptor 5110 is provided in a cigarette or the aerosol generating unit 200, which is an aerosol product.

[0641] The control unit 100 controls the temperature of the susceptor 5110 by varying the amplitude, frequency, etc. of the alternating current supplied to the first coil 5131 in accordance with a preset temperature profile.

[0642] In step S1420, the control unit 100 induces magnetism in the susceptor 5110 via the second coil 5132 in the second section.

[0643] The control unit 100 controls the DC current supplied to the second coil 5132 in the second section. At this time, the control unit 100 does not need to supply power to the first coil 5131. When a DC current is supplied to the second coil 5132, a magnetic field is formed outside the second coil 5132. When the susceptor 5110 is exposed to the magnetic field, a magnetic moment reacts inside the susceptor 5110, and the susceptor 5110 is magnetized.

[0644] In step S1430, the magnetic force sensing unit senses a change in magnetic force due to a change in temperature of the susceptor 5110 in the second section.

[0645] The method of sensing magnetic force by the susceptor 5110 in the second section has been described above. That is, the magnetic force sensing unit converts the magnetic force value corresponding to the temperature value of the susceptor 5110 into a voltage form and outputs it.

[0646] On the other hand, the size of the first section is set larger than the size of the second section in order to minimize the temperature change of the susceptor 5110 and to measure the temperature of the susceptor 5110 accurately.

[0647] In step S1440, the control unit 100 calculates the temperature of the susceptor 5110 based on the change in magnetic force.

[0648] The method by which the control unit 100 calculates the temperature in the second section has been described above. That is, the control unit 100 obtains the temperature of the susceptor 5110 corresponding to the output value output by the magnetic force sensor from the lookup table stored in the memory unit 800.

[0649] As another example, the control unit 100 obtains the magnetic force difference between a first magnetic force value of the susceptor 5110 sensed at a first time point after starting heating and a second magnetic force value at a second time point a predetermined time after the first time point.

[0650] Furthermore, the control unit 100 may obtain the temperature of the susceptor 5110 corresponding to the magnetic force value difference from a lookup table stored in the storage unit 800.

[0651] As described above, the magnetic force sensing unit may be provided separately in the aerosol generating unit, or may use a magnetic sensor in the sensing unit or camera module of the mobile communication terminal.

[0652] FIG. 52 is a diagram showing an embodiment of a mobile communication terminal that can easily control the temperature and system of an aerosol generating unit.

[0653] To facilitate the explanation of the embodiments, a block diagram is shown based on a logical configuration, and the blocks correspond to the physical components described above.

[0654] Referring to FIG. 52, the mobile communication terminal according to the embodiment includes a control unit 100, an aerosol generating unit 200, a power supply unit 300, a sensing unit 500, and a memory unit 800.

[0655] Although not shown in FIG. 52, the susceptor may be included in the aerosol-generating unit 200 or in a cigarette coupled to the aerosol-generating unit 200 .

[0656] The coil section of the aerosol generation section 200 includes at least one coil, and the coil section includes a first coil and a second coil that are wound alternately or wound in different regions from each other.

[0657] The power supply unit 300 supplies power to the internal components of the aerosol generating unit 200. The power supply unit 300 provides DC power, and a power converter (not shown) of the aerosol generating unit 200 converts the DC power provided by the power supply unit 300 into AC power and transmits it to the aerosol generating unit 200. The aerosol generating unit 200 heats a susceptor of the aerosol generating unit 200 by magnetic induction using the AC power.

[0658] The control unit 100 controls the power supplied to the coil of the aerosol generation unit 200.

[0659] For example, the control unit 100 heats the susceptor by controlling the AC current supplied to the first coil. In another embodiment, the control unit 100 heats the susceptor by controlling the AC current supplied to the first coil, or induces magnetism in the susceptor by controlling the DC current supplied to the first coil.

[0660] In another embodiment, the control unit 100 heats the susceptor by controlling the AC current supplied to the first coil, and induces magnetism in the susceptor by controlling the DC current supplied to the second coil.

[0661] When the control unit 100 heats the susceptor of the aerosol generating unit 200 to induce magnetism, the magnetic force sensing unit or magnetic sensor of the sensing unit 500 senses a change in the magnetic force of the susceptor of the aerosol generating unit 200 .

[0662] In this embodiment, the magnetic force sensing unit or magnetic sensor of the sensing unit 500 is physically included in a composite sensor chip of the mobile communication terminal or in a camera module.

[0663] Based on the change in magnetic force sensed by the magnetic force sensing unit or magnetic sensor, the control unit 100 calculates the temperature of the susceptor of the aerosol generating unit 200. The relationship between the change in magnetic force of the susceptor and the temperature has been described above.

[0664] The storage unit 800 stores matching data or a lookup table relating to the relationship between the susceptor magnetic force change and the temperature change.

[0665] The control unit 100 calculates the temperature of the susceptor based on the matching data and the lookup table stored in the storage unit 800.

[0666] Hereinafter, another embodiment will be described in which the temperature of a susceptor in an aerosol generating unit is sensed and used to control the system of a mobile communication terminal.

[0667] 53 is a block diagram showing a simplified configuration of a mobile communication terminal including an aerosol generating unit. Hereinafter, a description that overlaps with the above description will be omitted.

[0668] Referring to FIG. 53, the mobile communication terminal includes a control unit 100, an aerosol generating unit 200, a power supply unit 300, a sensing unit 500, and an output unit 700.

[0669] As described above, the control unit 100 performs overall control operations related to the operation of the mobile communication terminal. Furthermore, the control unit 100 performs control operations related to aerosol generation by the aerosol generating unit 200. For example, the control unit 100 performs control operations such as controlling the power applied to the aerosol generating unit 200 and back-counting (or counting) of a counter related to the aerosol generating unit 200. The control unit also controls the performance of the display module 710 included in the output unit 700 to generate output related to the visual, auditory, or tactile senses.

[0670] As described above, when a stick is accommodated, the aerosol generating unit 200 generates an aerosol by heating the stick. The aerosol generating unit 200 includes the external induction heater and the internal insertion type induction heater described with reference to FIGS. 4 to 27 in relation to heating the stick. In particular, the aerosol generating unit 200 performs operations related to the generation of an aerosol based on the external induction heater shown in FIGS. 4 to 17 that inductively heats a susceptor included in the stick.

[0671] The power supply unit 300 includes a rechargeable battery that supplies DC power to the mobile communication terminal, and is electrically connected to the aerosol generating unit 200 to supply DC power to the aerosol generating unit 200.

[0672] As described above, the sensing unit 500 includes one or more sensors for sensing at least one of information within the mobile communication terminal, information about the surrounding environment surrounding the mobile communication terminal, and user information. The sensing unit 500 also includes sensors for sensing voltages, currents, etc., of components included in the mobile communication terminal.

[0673] As mentioned above, when the aerosol generation unit 200 is based on an external induction heater, it is difficult to directly measure the temperature of the physically separated susceptor, so the control unit 100 needs to estimate the temperature of the susceptor using an indirect temperature measurement method in order to control the power of the aerosol generation unit 200.

[0674] Specifically, the control unit 100 estimates the temperature of the susceptor by considering the relationship between the equivalent resistance and temperature of the susceptor. To this end, the sensing unit 500 separately senses the current, voltage, and power of the aerosol generating unit 200 among the components included in the mobile communication terminal and generates first load information. In this case, the control unit 100 acquires the first load information from the sensing unit 500 and indirectly estimates the temperature of the susceptor by estimating the equivalent resistance of the susceptor based on the first load information. The control unit 100 controls the power applied to the aerosol generating unit 200 based on the estimated susceptor temperature.

[0675] Alternatively, the mobile communication terminal or the control unit 100 measures or estimates the temperature of the susceptor or aerosol generation unit by further considering at least one of a change in resonance frequency (see FIGS. 36 to 45), a change in magnetism (see FIGS. 46 to 52), and a change in susceptor characteristics (see FIGS. 57 to 60). Alternatively, for example, the control unit 100 directly measures or estimates the temperature of the susceptor or aerosol generation unit 200 using a sensor (included in the sensing unit) that senses the temperature of the display module 710, or the control unit 100 estimates or measures the temperature of the susceptor or aerosol generation unit 200 based on at least one of a change in resonance frequency (see FIGS. 36 to 45), a change in magnetism (see FIGS. 46 to 52), an equivalent resistance (see FIGS. 53 to 56), and a change in susceptor characteristics (see FIGS. 57 to 60) calculated or sensed by the sensing unit 500.

[0676] Alternatively, the mobile communication terminal or the control unit 100 controls the performance of the display module 710 based on the estimated or measured temperature of the susceptor or aerosol generation unit 200 and / or the temperature of the display module (see FIGS. 61 to 65). For example, the mobile communication terminal estimates second temperature information based on the equivalent resistance or a change in the equivalent resistance of the susceptor or aerosol generation unit 200, and controls the performance of the display module based on the estimated second temperature information and the first temperature information measured for the display module 710.

[0677] Alternatively, the display module 710 may include a flexible display including a first region in contact with a first surface of the aerosol generating unit 200 (see FIGS. 66 to 78). When insertion of a stick into the aerosol generating unit 200 is detected, the first region of the flexible display is deformed into a curved surface. Also, as described above, the mobile communication terminal or the control unit 100 calculates the equivalent resistance (or change in magnetism, magnetic flux density, or resonant frequency) of the aerosol generating unit 200 or the susceptor in response to the change in the curve of the first region, and estimates the temperature of the susceptor.

[0678] Alternatively, the mobile communication terminal further includes a heat pipe whose interior is vacuum-treated and contains a fluid (see FIGS. 79 to 83). One region of the heat pipe is connected to a first region of the aerosol generator, and another region of the heat pipe is connected to a second region of the mobile communication terminal. The control unit 100 predicts a temperature change of the aerosol generator 200 by further considering the thermal conductivity of the heat pipe, and controls the power of the aerosol generator 200 or the performance of the display module 710 based on the predicted temperature change.

[0679] Alternatively, the mobile communication terminal may include an antenna having a conductive patch and a ground spaced apart from the patch, the antenna being coupled to the aerosol generator and positioned within the body of the aerosol generator (see FIGS. 28 to 35).

[0680] Hereinafter, a method for the control unit 100 to estimate the equivalent resistance of the susceptor in order to estimate the temperature of the susceptor will be described in detail.

[0681] FIG. 54 is a diagram for explaining an aerosol generating unit based on an external induction heating method.

[0682] Referring to FIG. 54, the aerosol generating unit 200 includes a DC / AC converting unit 6011, an impedance matching unit 6011, and an inductor 6015.

[0683] The aerosol generator receives DC current and / or DC power from a DC power source 6019 and converts the DC current into AC current through a DC / AC converter 6011. Here, the DC power source 6019 is the power supply unit 300 included in the mobile communication terminal. The AC current is impedance matched by an impedance matching unit 6011 (or a transformer) and then applied to an inductor 6015. The inductor 6015 receives the AC current and generates an alternating magnetic field whose polarity changes according to the frequency of the AC current. The alternating magnetic field generates heat in a susceptor 6017 included in the stick. Here, the inductor 6015 has a cylindrical shape wound in a spiral, but is not limited thereto and can be formed of a coil of various shapes capable of generating the alternating magnetic field.

[0684] The stick includes a material capable of generating an aerosol and a susceptor 6017. The susceptor 6017 includes a conductor that is inductively heated by the inductor 6015. Specifically, the susceptor 6017 includes a conductor that generates heat when an alternating magnetic field is generated by the inductor 6015, such as stainless steel, that generates heat when the alternating magnetic field is generated. The susceptor 6017 may have various shapes, such as a rectangular, circular, or elliptical shape. The heat generated when the susceptor 6017 is inductively heated is transferred to the material capable of generating an aerosol contained in the stick, and the transferred heat causes the material to generate an aerosol.

[0685] As described above, the sensing unit generates the first load information by measuring the voltage of the DC power supply and the DC current applied to the DC / AC converter 6011 or the aerosol generator. For example, the sensing unit senses the DC current and DC voltage applied to the aerosol generator through electrical connection with the DC power supply and / or the DC / AC converter 6011.

[0686] The control unit receives the first load information from the sensing unit, calculates an equivalent resistance for the aerosol generation unit based on the first load information, and controls a DC / AC conversion unit 6011 of the aerosol generation unit to control the power applied to the aerosol generation unit based on the calculated equivalent resistance.

[0687] The equivalent resistance calculated by the control unit based on the first load information will be described in more detail below.

[0688] FIG. 55 is a diagram for explaining the equivalent resistance of an aerosol generating unit that houses a stick including a susceptor.

[0689] 55, the equivalent resistance RT of the aerosol generation unit corresponds to the sum of the first resistance RTL of the inductor and the second resistance RTS of the susceptor. Here, the resistance of the DC / AC conversion unit described with reference to FIG. 55 has a resistance value that is negligibly low compared to the resistances of the susceptor and the inductor. Here, the second resistance RTS of the susceptor changes depending on the temperature.

[0690] For example, the second resistance RTS of the susceptor increases in response to an increase in the susceptor temperature and decreases in response to a decrease in the susceptor temperature. Because the second resistance RTS of the susceptor changes with temperature, the equivalent resistance RT including the second resistance RTS of the susceptor also changes with temperature. In this case, the equivalent resistance RT corresponds to a single value of the susceptor temperature, and the equivalent resistance RT and the susceptor temperature have a monotonic function relationship. That is, since the equivalent resistance RT and the susceptor temperature have a one-to-one relationship, the correspondence between the equivalent resistance RT and the susceptor temperature is analyzed in advance, and a lookup table for the correspondence between the equivalent resistance RT and the susceptor temperature is pre-constructed. In this case, the control unit estimates the susceptor temperature corresponding to the calculated equivalent resistance based on the predefined correspondence between the equivalent resistance RT and the susceptor temperature.

[0691] Hereinafter, a method for the control unit to control the power of the aerosol generation unit based on the correspondence relationship between the susceptor temperature and the equivalent resistance RT will be described in detail.

[0692] FIG. 56 is a flowchart for explaining a method in which the control unit controls the power of the aerosol generation unit based on the calculated equivalent resistance.

[0693] 56, the control unit detects or monitors whether a stick is placed in the aerosol generating unit (S6501). For example, the control unit detects whether a stick is placed in the aerosol generating unit based on an optical sensor, a pressure sensor, etc. included in the aerosol generating unit.

[0694] When a stick is accommodated in the aerosol generation unit, the control unit starts applying power to the aerosol generation unit and acquires first load information from the sensing unit (S6503). Here, the first load information includes information regarding the voltage applied to the aerosol generation unit and the current to the aerosol generation unit, as described above. As described above, the voltage and / or current included in the first load information is a DC voltage and / or a DC current.

[0695] The control unit calculates the equivalent resistance of the aerosol generation unit based on the first load information (S6505). For example, the control unit calculates the equivalent resistance of the aerosol generation unit based on the relationship between voltage and current included in the first load information according to Ohm's law. For example, the control unit calculates the equivalent resistance based on the value obtained by dividing the voltage by the current. As described above, the equivalent resistance increases or decreases depending on the temperature change of the susceptor. For example, as the temperature of the susceptor increases, the equivalent resistance also increases, and as the temperature of the susceptor decreases, the equivalent resistance also decreases. Meanwhile, the control unit can also calculate the equivalent resistance based on the rate of change of voltage.

[0696] The control unit periodically or aperiodically acquires first load information from the sensing unit and calculates a change in the equivalent resistance based on the first load information acquired periodically or aperiodically. In this case, the control unit estimates whether the temperature of the susceptor will increase or decrease based on the change in the equivalent resistance. For example, if the change in the equivalent resistance is a negative value, the control unit estimates that the temperature of the susceptor has decreased, and if the change in the equivalent resistance is a positive value, the control unit estimates that the temperature of the susceptor has increased.

[0697] The control unit controls the power or amount of power applied to the aerosol generation unit based on the equivalent resistance calculated based on the first load information (S6507). Specifically, as described above, the control unit estimates the susceptor temperature corresponding to the calculated equivalent resistance based on a predefined correspondence relationship between the equivalent resistance and the susceptor temperature (e.g., from a preconfigured lookup table). In this case, the control unit determines whether the estimated susceptor temperature has reached a first critical temperature. If the estimated susceptor temperature has reached or is equal to or higher than the first critical temperature, the control unit stops applying power to the aerosol generation unit. Alternatively, if the estimated susceptor temperature has reached or is equal to or higher than the first critical temperature, the control unit applies a preset minimum amount of power to the aerosol generation unit.

[0698] Thereafter, the control unit continuously (or periodically) calculates an equivalent resistance based on the first load information, and increases (or resumes application of power to) or decreases the amount of power applied to the aerosol generation unit based on the change in the equivalent resistance. Through this operation, the control unit can maintain the temperature of the susceptor within a predetermined range around the first critical temperature. Alternatively, the control unit can calculate a temperature change value, which is the difference between the temperature of the first susceptor corresponding to the first equivalent resistance calculated at a first time point and the temperature of the second susceptor corresponding to the second equivalent resistance calculated at a second time point (a time point immediately after the first time point), based on the first load information acquired periodically or aperiodically. In this case, the control unit increases or decreases the amount of power applied to the aerosol generation unit based on the temperature change value.

[0699] For example, the control unit adjusts the period (switching period) of the DC / AC converter included in the aerosol to control the amount of power applied to the aerosol generator. For example, when the change in the equivalent resistance is a negative value, the control unit decreases the period of the DC / AC converter (increases the AC frequency) and increases the power applied to the aerosol generator. When the change in the equivalent resistance is a positive value, the control unit increases the period of the DC / AC converter (decreases the AC frequency) and decreases the power applied to the aerosol generator.

[0700] The control unit also performs a control operation related to the aerosol generator based on the equivalent resistance. Specifically, the control unit backoff-counts (or counts) a counter value related to the aerosol generator based on a change in the equivalent resistance. Here, the counter value is set to a base value equal to the maximum number of times the aerosol generator can generate aerosol (or the maximum number of puffs) after the stick is retracted. For example, if the change in the equivalent resistance is equal to or greater than a first critical change value, the control unit backoff-counts the counter value by one. The first critical change value is a preset value based on the amount of decrease in the equivalent resistance of the aerosol generator (or the amount of decrease in the temperature of the susceptor) caused by the inflow of outside air due to the inhalation of aerosol by a user of the mobile communication terminal or the aerosol generator. For example, if the temperature of the susceptor decreases to an average first temperature due to the inflow of outside air, the first critical change value is preset to a value corresponding to the amount of change in equivalent resistance caused by the decrease in the first temperature or the first temperature.

[0701] The control unit outputs the back-off counted counter value through the display module. When the counter value reaches 0, the control unit stops applying power to the aerosol generating unit and initializes or resets the counter value to an initial value.

[0702] Alternatively, the control unit acquires first temperature information about the display module from the sensing unit and determines an increase rate and / or decrease rate of the power applied to the aerosol generation unit based on the first temperature information. For example, the increase rate of the amount of power when the first temperature information is equal to or greater than a predetermined critical temperature is preset to be smaller than the increase rate of the amount of power when the first temperature information is below the predetermined critical temperature. Or, the decrease rate of the amount of power when the first temperature information is equal to or greater than the predetermined critical temperature is preset to be larger than the decrease rate of the amount of power when the first temperature information is below the predetermined critical temperature. In this case, the control unit increases the amount of power at a slower rate or decreases the amount of power at a faster rate when the first temperature information is equal to or greater than the critical temperature, thereby maximally delaying the temperature of the display module from increasing to the maximum allowable temperature. Here, the predetermined critical temperature is set to a temperature that is lower than the maximum allowable temperature but at which the first temperature information (or the temperature of the display module) is likely to reach the maximum allowable temperature within a predefined first time period due to the temperature of the susceptor. For example, the first time period is determined based on an average operating time or a predefined duration from when a stick is accommodated in the aerosol generating unit until the generation of the aerosol ends.

[0703] Alternatively, the control unit may limit the performance of the mobile communication terminal including the aerosol generation unit when a stick is inserted into the aerosol generation unit. For example, when a stick is inserted into the aerosol generation unit, the control unit switches the mobile communication terminal to a standby mode (e.g., a terminal mode with minimum standby power by turning off the display of a display module) to minimize power consumption of the internal components of the mobile communication terminal. In this case, the internal equivalent resistance of the mobile communication terminal (other internal equivalent resistances excluding the equivalent resistance of the aerosol generation unit) is maintained constant. Therefore, the control unit may detect a change in the equivalent resistance of the susceptor due to a change in the temperature of the susceptor from the equivalent resistance of the mobile communication terminal, and estimate the temperature of the susceptor based on the detected change.

[0704] Hereinafter, another embodiment will be described in which the temperature of a susceptor in an aerosol generating unit is sensed and used to control the system of a mobile communication terminal.

[0705] 57 is a block diagram showing a simplified configuration of a mobile communication terminal including an aerosol generating unit. Hereinafter, a description that overlaps with the above description will be omitted.

[0706] Referring to FIG. 57, the mobile communication terminal includes a control unit 100, an aerosol generating unit 200, a power supply unit 300, a sensing unit 500, and an output unit 700.

[0707] As described above, the control unit 100 performs overall control operations related to the operation of the mobile communication terminal. Furthermore, the control unit 100 performs control operations related to aerosol generation by the aerosol generating unit 200. For example, the control unit 100 performs control operations such as controlling the power applied to the aerosol generating unit 200 and back-counting (or counting) of a counter related to the aerosol generating unit 200. The control unit also controls the performance of the display module 710 included in the output unit 700 to generate output related to the visual, auditory, or tactile senses.

[0708] As described above, when a stick is accommodated, the aerosol generating unit 200 generates an aerosol by heating the stick. The aerosol generating unit 200 includes the external induction heater and the internal insertion type induction heater described with reference to FIGS. 4 to 27 in relation to heating the stick. In particular, the aerosol generating unit 200 performs operations related to the generation of an aerosol based on the external induction heater described with reference to FIGS. 4 to 17 that inductively heats a susceptor included in the stick.

[0709] The power supply unit 300 includes a rechargeable battery capable of supplying DC power to the mobile communication terminal, and is electrically connected to the aerosol generating unit 200 to supply DC power to the aerosol generating unit 200.

[0710] As described above, the sensing unit 500 includes one or more sensors for sensing at least one of information within the mobile communication terminal, information about the surrounding environment surrounding the mobile communication terminal, and user information. The sensing unit 500 also includes a characteristic change sensing unit 6801 for sensing a change in magnetism associated with the aerosol generating unit 200 or a susceptor included in the stick. Alternatively, the characteristic change sensing unit 6801 may measure or estimate power loss associated with the aerosol generating unit 200 based on the voltage and current associated with the aerosol generating unit 200, and sense a change in magnetism associated with the susceptor based on the estimated power loss.

[0711] The control unit 100 can indirectly measure or estimate the temperature of the susceptor in a predetermined manner using the characteristic change sensing unit 6801, even if the susceptor of the stick housed in the aerosol generation unit 200 based on the external induction heater is physically separated. For example, as described below, the control unit 100 senses a characteristic change (change in magnetism and / or change in power loss) associated with the susceptor due to a change in the susceptor temperature, estimates the temperature of the susceptor, and controls the power applied to the aerosol generation unit 200 based on the estimated susceptor temperature.

[0712] Alternatively, the mobile communication terminal or the control unit 100 may measure or estimate the temperature of the susceptor or aerosol-generating unit 200 by further considering at least one of a change in resonance frequency (see FIGS. 36 to 45), a change in magnetism (see FIGS. 46 to 52), and an equivalent resistance (see FIGS. 53 to 56). Alternatively, for example, the control unit 100 may directly measure or estimate the temperature of the susceptor or aerosol-generating unit 200 through a sensor (included in the sensing unit) that senses the temperature of the display module 710. Alternatively, the control unit 100 may estimate or measure the temperature of the susceptor or aerosol-generating unit 200 based on at least one of a change in resonance frequency (see FIGS. 36 to 45), a change in magnetism (see FIGS. 46 to 52), an equivalent resistance (see FIGS. 53 to 56), and a change in susceptor characteristics (see FIGS. 57 to 60) calculated or sensed through the sensing unit 500.

[0713] Alternatively, the mobile communication terminal or the control unit 100 controls the performance of the display module based on the estimated or measured temperature of the susceptor or aerosol generating unit 200 and / or the temperature of the display module (see FIGS. 61 to 65). For example, the mobile communication terminal estimates second temperature information based on the magnetic change or characteristic change of the susceptor, and controls the performance of the display module 710 based on the estimated second temperature information and the first temperature information measured for the display module.

[0714] Alternatively, the display module 710 may include a flexible display including a first region in contact with a first surface of the aerosol generating unit 200 (see FIGS. 66 to 78). When the insertion of a stick into the aerosol generating unit 200 is detected, the first region of the flexible display is deformed into a curved surface. Also, as described above, the mobile communication terminal or the control unit 100 senses a change in the characteristics or magnetism of the susceptor (or a change in equivalent resistance, magnetism, or resonant frequency) in response to the change in the curve of the first region, and confirms that the susceptor has reached a predetermined temperature.

[0715] Alternatively, the mobile communication terminal may further include a heat pipe whose interior is vacuum-treated and contains a fluid (see FIGS. 79 to 83). One region of the heat pipe is connected to a first region of the aerosol generator, and another region of the heat pipe is connected to a second region of the mobile communication terminal. The control unit 100 predicts a temperature change of the aerosol generator 200, further taking into account the thermal conductivity of the heat pipe, and controls the power to the aerosol generator 200 or the performance of the display module 710 according to the predicted temperature change.

[0716] Alternatively, the mobile communication terminal may include an antenna having a conductive patch and a ground spaced apart from the patch, the antenna being coupled to the aerosol generator and positioned in the body of the aerosol generator (see FIGS. 28 to 35).

[0717] An embodiment showing a method for sensing the change in the properties of the susceptor (or the change in the magnetic properties of the susceptor) will now be described in detail.

[0718] FIG. 58 is a diagram illustrating a method in which the aerosol generating unit inductively heats a susceptor contained in a stick.

[0719] Referring to FIG. 58, the aerosol generation unit 200 includes a DC / AC conversion unit 6711, an impedance matching unit 6711, and an inductor 6715.

[0720] The aerosol generator 200 receives DC current and / or DC power from a DC power source 6719 and converts the DC current into AC current through a DC / AC converter 6711. Here, the DC power source 6719 is the power supply unit 300 included in the mobile communication terminal. The AC current is impedance matched by an impedance matching unit 6711 (or a transformer) and then applied to an inductor 6715. The inductor 6715 receives the AC current and generates an alternating magnetic field whose polarity changes according to the frequency of the AC current. The alternating magnetic field generates heat in a susceptor 6717 included in the stick. Here, the inductor 6715 is a cylindrical coil wound in a spiral, but is not limited thereto and can be formed of various coil shapes capable of generating the alternating magnetic field.

[0721] The susceptor 6717 is contained in a stick adjacent to the aerosol-generating material. The susceptor 6717 is physically separated from the inductor 6715. The susceptor 6717 is inductively heated by an alternating magnetic field generated by the inductor 6715. For example, the susceptor 6717 comprises a conductor such as stainless steel that generates heat due to the alternating magnetic field generated by the inductor 6715. The susceptor 6717 can have a variety of shapes, such as rectangular, circular, or elliptical.

[0722] Furthermore, the susceptor 6717 includes a ferromagnetic material or a ferromagnetic substance whose magnetism changes from ferromagnetic to paramagnetic when heated to a predetermined temperature (or Curie temperature). In this case, the susceptor 6717 loses its ferromagnetic properties and acquires paramagnetic properties when heated to the predetermined temperature. Here, the predetermined temperature is the optimum temperature at which the aerosol-generating material is suitable for generating aerosol. Furthermore, when the susceptor 6717 is heated to the predetermined temperature, the magnetic change of the susceptor 6717 may significantly reduce power loss below a predetermined value.

[0723] FIG. 59 is a diagram for explaining a method in which the characteristic change sensing unit senses a change in the characteristics of the susceptor.

[0724] 59, the mobile communication terminal includes a characteristic change sensor 6801 and an aerosol generator 200. Here, the characteristic change sensor 6801 is disposed at a position where it can sense the magnetism of the susceptor 6810, and may be included in the aerosol generator 200, if necessary.

[0725] The aerosol generation unit 200 includes an inductor 6820. A stick including a susceptor 6810 is accommodated in the aerosol generation unit 200. The inductor 6820 includes a coil wound along the length of the aerosol generation unit 200 from the outer surface of the accommodation space. When an alternating current is applied to the inductor 6831, the inductor 6831 generates an alternating magnetic field, which heats the susceptor 6810.

[0726] The susceptor 6810 included in the stick may change its magnetic property from ferromagnetic to paramagnetic when heated above a predetermined temperature, or from paramagnetic to ferromagnetic when cooled below the predetermined temperature. Furthermore, the change in magnetic property of the susceptor 6810 may cause a sudden increase or decrease in power loss. For example, when the susceptor 6810 is heated above the predetermined temperature and its ferromagnetic properties change to paramagnetic properties, the power loss of the susceptor 6810 decreases significantly. In contrast, when the susceptor 6810 is cooled below the predetermined temperature and its magnetic properties change from paramagnetic to ferromagnetic, the power loss of the susceptor 6810 increases significantly.

[0727] The property change detector 6801 transmits information about the change in the magnetism of the susceptor 6810, which is detected based on the change in the magnetism of the susceptor 6810, to the controller 100. For example, if the magnetism of the susceptor 6810 detected at a first time point (after the susceptor 6810 is heated to a predetermined temperature or higher) is not detected at a second time point, which is the next detection time point, the property change detector 6801 transmits first information about the change in the magnetism of the susceptor to the controller 100. In this case, the controller 100 determines that the magnetism of the susceptor has changed from ferromagnetic to paramagnetic based on the first information. Alternatively, if the magnetism of the susceptor 6810, which has not been detected since the second time point (when the susceptor 6810 is cooled below the predetermined temperature), is detected again at a third time point, the characteristic change detection unit 6801 transmits second information regarding the change in the magnetism of the susceptor to the control unit 100. In this case, the control unit 100 determines that the magnetism of the susceptor has changed from paramagnetic to ferromagnetic. Meanwhile, the characteristic change detection unit 6801 may be a geomagnetic field sensor included in the mobile communication terminal. Alternatively, the characteristic change detection unit 6801 may provide only the first information of the first and second information to the control unit 100.

[0728] Alternatively, the characteristic change detector 6801 transmits information regarding the presence or absence of a change in the magnetic property of the susceptor 6810 to the controller 100 based on the power loss measured for the susceptor 6810 or the aerosol generator 200. For example, if the power loss measured for the susceptor 6810 or the aerosol generator 200 decreases by a predetermined amount or more, the characteristic change detector 6801 transmits the first information regarding the change in the magnetic property of the susceptor 6810 to the controller 100. Alternatively, if the power loss measured for the susceptor 6810 or the aerosol generator 200 increases by a predetermined amount or more, the characteristic change detector 6801 transmits the second information regarding the change in the magnetic property of the susceptor 6810 to the controller 100.

[0729] Below, an embodiment of a method in which the control unit 100 estimates the temperature of the susceptor 6810 based on the first information and second information of the characteristic change sensing unit 6801 and controls the power of the aerosol generating unit 200 based on the estimated temperature of the susceptor 6810 will be described in detail.

[0730] FIG. 60 is a diagram for explaining a method in which the control unit controls the power to the aerosol generation unit based on the estimated temperature of the susceptor.

[0731] 60, the control unit detects whether a stick is present in the aerosol generating unit (S6901). When the control unit detects the presence of a stick in the aerosol generating unit, it starts applying power to the aerosol generating unit to inductively heat the susceptor.

[0732] Next, the control unit estimates the temperature of the susceptor based on the information acquired from the characteristic change sensing unit (S6903). Specifically, the control unit receives first information from the characteristic change sensing unit when the magnetism of the susceptor has changed from ferromagnetic to paramagnetic. In this case, the control unit estimates, based on the first information, that the temperature of the susceptor is at or above a predetermined temperature (or Curie temperature). Alternatively, the control unit receives second information from the characteristic change sensing unit when the magnetism of the susceptor has changed from paramagnetic to ferromagnetic. In this case, the control unit estimates, based on the second information, that the temperature of the susceptor is below a predetermined temperature (or Curie temperature).

[0733] Next, the control unit controls the power of the aerosol generation unit based on the estimated susceptor temperature (S6905). Specifically, the control unit estimates, based on the first information, that the susceptor temperature has reached the first temperature or the Curie temperature. In this case, the control unit stops applying power to the aerosol generation unit (or reduces the amount of power applied). That is, the control unit stops applying power to the aerosol generation unit and cools the susceptor. Alternatively, the control unit estimates, based on the second information, that the susceptor temperature is lower than the second temperature or the Curie temperature. In this case, the control unit resumes applying power to the aerosol generation unit (or increases the amount of power) and heats the susceptor to the predetermined temperature or above. In this manner, the control unit can maintain the susceptor temperature within a predetermined range from the predetermined temperature or the Curie temperature.

[0734] Alternatively, the control unit controls the power to the aerosol generator based on first information transmitted by the characteristic change detection unit. In other words, the control unit receives only the first information from the characteristic change detection unit. For example, the control unit estimates that the temperature of the susceptor is equal to or higher than the predetermined temperature based on the first information and stops applying power to the aerosol generator. In this case, the control unit stops applying power for a preset time and resumes applying power to the aerosol generator after the preset time has elapsed. Here, the preset time is set based on temperature information of a display module included in the mobile communication terminal. For example, if the temperature of the display module is lower than a first critical temperature, the preset time is set to a time set as a base value. If the temperature of the display module is equal to or higher than the first critical temperature, the preset time is set to or adjusted to a value smaller than the base value.

[0735] Alternatively, the control unit may backoff the counter value associated with the aerosol generator based on the detection of the magnetic change of the susceptor. For example, when the control unit receives second information from the characteristic change detection unit, the control unit backoffs the counter value by one. The control unit may also output the backoff counter value using the display module.

[0736] 61 is a block diagram showing an example of a mobile communication terminal including an aerosol generating unit. Hereinafter, a description that overlaps with the above description will be omitted.

[0737] Referring to FIG. 61, the mobile communication terminal includes a control unit 100, an aerosol generating unit 200, an output unit 700, and a sensing unit 500.

[0738] The output unit 700 includes a display module 710 for generating an output related to a visual, an auditory, or a tactile sense, etc. The sensing unit 500 includes an environmental sensor that senses the temperature of the display module 710 and generates first temperature information.

[0739] The control unit 100 acquires first temperature information including the sensed temperature of the display module 710 from the sensing unit 500. The control unit 100 controls the performance of the display module 710 based on the first temperature information. Here, the performance of the display module 710 includes brightness, frame rate, resolution, etc.

[0740] For example, the controller 100 reduces or increases the performance of the display module 710 based on the first temperature information. Here, the reduction in performance of the display module 710 refers to a reduction in the brightness, a reduction in the frame rate, or a reduction in the resolution, and the increase in performance of the display module 710 refers to an increase in the brightness, an increase in the frame rate, or an increase in the resolution. The controller 100 prevents the temperature of the display module 710 from rising to a maximum allowable temperature of the display module 710 by controlling the performance of the display module 710 based on the first temperature information. Here, the maximum allowable temperature is the maximum temperature at which the display module 710 can operate normally. Alternatively, control parameters related to the performance of the display module 710 corresponding to the first temperature information are preset. For example, a lookup table mapping control parameters corresponding to the first temperature information is pre-stored in the mobile communication terminal, and the controller 100 controls the performance of the display module 710 using the control parameters for the performance corresponding to the first temperature information based on the lookup table.

[0741] Alternatively, the control unit 100 may further consider second temperature information measured for the aerosol generation unit 200 as temperature information for controlling the performance of the display module 710, depending on whether a stick is housed in the aerosol generation unit 200. For example, when no stick is housed in the aerosol generation unit 200, the control unit 100 controls the performance of the display module 710 based on first temperature information for the display module 710 from the sensing unit 500, whereas when a stick is housed in the aerosol generation unit 200, the control unit 100 controls the performance of the display module 710 by further considering second temperature information for the aerosol generation unit 200 obtained from the sensing unit 500. Here, the second temperature information is temperature information for the aerosol generation unit 200, and more specifically, includes an airflow path temperature for the airflow that flows into and is discharged from the aerosol generation unit 200.

[0742] Alternatively, the sensing unit 500 turns on / off electrical connection for temperature sensing with the display module 710 and / or the aerosol generation unit 200 under the control of the control unit 100. For example, when a stick is not accommodated in the aerosol generation unit 200, the sensing unit 500 turns on electrical connection for temperature sensing with the display module 710 and turns off electrical connection for temperature sensing with the aerosol generation unit 200. On the other hand, when a stick is accommodated in the aerosol generation unit 200, the sensing unit 500 turns on electrical connection for temperature sensing with the aerosol generation unit 200.

[0743] Alternatively, the mobile communication terminal or the control unit 100 measures or estimates the temperature of the susceptor or the aerosol generation unit by further considering at least one of a change in resonance frequency (see FIGS. 36 to 45), a change in magnetism (see FIGS. 46 to 52), an equivalent resistance (see FIGS. 53 to 56), and a change in susceptor characteristics (see FIGS. 57 to 60). For example, the control unit 100 measures or estimates the temperature of the susceptor or the aerosol generation unit 200 based on at least one of a change in resonance frequency (see FIGS. 36 to 45), a change in magnetism (see FIGS. 46 to 52), an equivalent resistance (see FIGS. 53 to 56), and a change in susceptor characteristics (see FIGS. 57 to 60) calculated or sensed by the sensing unit 500.

[0744] Alternatively, the display module 710 may include a flexible display including a first region in contact with a first surface of the aerosol generating unit 200 (see FIGS. 66 to 78). When the insertion of a stick into the aerosol generating unit 200 is detected, the first region of the flexible display is deformed into a curved surface. Also, as described above, the mobile communication terminal or the control unit 100 starts measuring second temperature information for the aerosol generating unit 200 in response to the change in the curve of the first region.

[0745] Alternatively, the mobile communication terminal further includes a heat pipe whose interior is vacuum-treated and contains a fluid (see FIGS. 79 to 83). One region of the heat pipe is connected to a first region of the aerosol generator, and another region of the heat pipe is connected to a second region of the mobile communication terminal. The control unit 100 predicts a temperature change of the aerosol generator 200 by further considering the thermal conductivity of the heat pipe, and controls the power of the aerosol generator 200 or the performance of the display module 710 based on the predicted temperature change.

[0746] Alternatively, the mobile communication terminal may include an antenna having a conductive patch and a ground spaced apart from the patch, the antenna being coupled to the aerosol generator and positioned in the body of the aerosol generator (see FIGS. 28 to 35).

[0747] Hereinafter, an embodiment showing a method in which the control unit 100 controls the performance of the display module 710 based on temperature information acquired depending on whether or not a stick is housed in the aerosol generating unit 200 will be described in detail.

[0748] 62 and 63 are diagrams for explaining a method in which the control unit controls the performance of the display module depending on whether or not the aerosol generating unit contains a stick.

[0749] 62, the control unit detects whether a stick is contained in the aerosol generating unit (S6101). The presence or absence of the stick is detected based on a pressure sensor, an optical sensor, etc. included in the aerosol generating unit.

[0750] The control unit controls the sensing unit to acquire first temperature information based on the fact that the aerosol generating unit does not detect the presence of a stick in the aerosol generating unit (S6103), where the first temperature information includes the temperature measured for the display module as described above.

[0751] The control unit controls the performance of the display module based on the first temperature information (S6104). For example, the control unit controls the performance of the display module to a first performance corresponding to the first value (or a preset control parameter corresponding to the first performance) based on the first temperature information including the first value. The control unit controls the performance of the display module to a second performance corresponding to the second value (or a preset control parameter corresponding to the second performance) based on the first temperature information including the second value. In this case, if the second value is higher than the first value, the second performance may be lower than the first performance. For example, the resolution and / or frame rate of the display module according to the second performance is lower than the resolution and / or frame rate of the display module according to the first performance.

[0752] 63(a), the control unit acquires first temperature information including a second value TP2 at a first time point, and controls the performance of the display module to have a frame rate (1 / T1) according to the second performance corresponding to the second value TP2. The control unit acquires first temperature information including a first value TP1 lower than the second value TP2 at a second time point after the first time point, and controls the performance of the display module to have a frame rate (1 / T2) according to the first performance corresponding to the first value TP1. At this time, since T2 is smaller than T1, the performance of the display module is improved.

[0753] Alternatively, referring to Figure 63(b), the control unit acquires first temperature information including a second value TP2 at a first time point and controls the performance of the display module to have a first resolution according to the second performance corresponding to the second value TP2. The control unit acquires first temperature information including a first value TP1 lower than the second value TP2 at a second time point after the first time point and controls the performance of the display module to have a second resolution according to the first performance corresponding to the first value TP1, where the second resolution is higher than the first resolution. The control unit may also control the performance of the display module by simultaneously controlling the resolution and frame rate of the display module based on the first temperature information.

[0754] The control unit controls the sensing unit to acquire first temperature information and second temperature information based on the detection of the insertion of a stick in the aerosol generation unit (S6105). As described above, the sensing unit is configured to sense not only the temperature of the display module but also the temperature of the aerosol generation unit, and the control unit controls the sensing unit to acquire the second temperature information in response to the detection of the insertion of a stick in the aerosol generation unit. Alternatively, the control unit can acquire only the second temperature information from the sensing unit.

[0755] Next, the control unit controls the performance of the display module based on the first temperature information and the second temperature information (S6106).

[0756] Specifically, the control unit corrects the first temperature information based on the second temperature information and controls the performance of the display module based on the corrected first temperature information. For example, an expected temperature increase associated with the first temperature information due to the temperature difference may be predefined, taking into account the temperature difference between the first temperature information and the second temperature information, the thermal conductivity between the display module and the aerosol generator, etc. For example, a second lookup table in which expected temperature increases are defined for each temperature difference may be predefined. The control unit corrects the first temperature information to additionally reflect the expected temperature increase determined based on the second lookup table, and controls the performance of the display module based on the corrected first temperature information. Alternatively, the second lookup table may predefine a temperature increase rate instead of the expected temperature increase corresponding to the temperature difference.

[0757] That is, when a stick is contained in the aerosol generating unit, the control unit controls the performance of the display module based on first temperature information corrected to reflect the expected temperature increase determined based on the temperature difference between the first temperature information and the second temperature information, rather than the current first temperature information of the display module.

[0758] For example, when the first temperature information includes a first value and the second temperature information includes a second value, the control unit calculates a first temperature difference, which is the difference between the first value and the second value, and determines an expected temperature increase corresponding to the first temperature difference (based on the second lookup table). The control unit corrects the first value to a third value by reflecting the expected temperature increase in the first value, and controls the performance of the display module based on the third value (or a temperature corresponding to the third value). For example, when a stick is not housed in the aerosol generating unit, the control unit controls the performance of the display module based on a first performance corresponding to the first value, or when a stick is housed in the aerosol generating unit, controls the performance of the display module based on a third performance corresponding to the third value instead of the first value. In this case, the first value is corrected to a higher third value, and the third performance corresponding to the third value sets a lower resolution and / or frame rate than the first performance corresponding to the first value. In this case, the control unit can minimize damage to the display module due to the high temperature of the aerosol generation unit by controlling the performance of the display module in advance, taking into account the expected temperature increase of the display module due to the temperature of the aerosol generation unit.

[0759] In addition, the control unit may perform operations related to the aerosol generator as well as the display module based on the second temperature information, the details of which will be described in detail below.

[0760] 64 and 65 are diagrams for explaining a method in which the control unit performs an operation related to the aerosol generation unit based on the second temperature information.

[0761] The control unit controls operations related to the aerosol generation unit based on the second temperature information, including controlling the operating state of the aerosol generation unit, controlling the power applied to the aerosol generation unit, and back-off counting of a counter value related to the aerosol generation unit.

[0762] 64, the control unit backs off the counter value of the counter associated with the aerosol generating unit based on the second temperature information, where the counter presets a counter value corresponding to the maximum number of aerosols generated via the aerosol generating unit (or the maximum number of puffs of an electronic cigarette).

[0763] Specifically, the control unit detects the placement of a stick in the aerosol generation unit (S6201). In this case, when the stick is placed in the aerosol generation unit, the control unit acquires second temperature information from the sensing unit. Here, the second temperature information is the airflow path temperature in the aerosol generation unit, as described above.

[0764] The control unit backs off a counter associated with the aerosol generator based on the second temperature information (S6203). Specifically, when a stick is accommodated in the aerosol generator, the control unit periodically acquires second temperature information of the aerosol generator and detects whether the temperature of the aerosol generator drops below a first critical temperature based on the periodically acquired second temperature information. When the temperature of the aerosol generator drops below the first critical temperature based on the second temperature information, the control unit backs off the counter value by one. Alternatively, the control unit outputs the backed off counter value via the display module to provide information about the remaining number of aerosol generations (or the remaining number of puffs) to a user of the aerosol generator or a user of the mobile communication terminal.

[0765] When the count value of the counter reaches 0, the control unit resets or initializes the counter value of the counter (i.e., sets it to the maximum number of times the aerosol is generated) (S6205).

[0766] The control unit also controls the amount of power applied to the aerosol generation unit based on the second temperature information.

[0767] Referring to FIG. 65, the control unit applies power to the aerosol generating unit in response to the detection of the placement of a stick in the aerosol generating unit (S6301).

[0768] The control unit controls the sensing unit described above, acquires the second temperature information for the aerosol generation unit, and controls the amount of power applied to the aerosol generation unit based on the second temperature information (S6303).

[0769] For example, when a stick is placed in the aerosol generating unit, the control unit applies power to the aerosol generating unit so that the second temperature information reaches a second critical temperature. If a decrease in the temperature of the aerosol generating unit is detected based on the second information periodically acquired thereafter, the control unit increases the amount of power applied to the aerosol generating unit. Alternatively, if an increase in the temperature of the aerosol generating unit is detected based on the second information periodically acquired thereafter, the second control unit decreases the amount of power applied to the aerosol generating unit.

[0770] Alternatively, the control unit controls the amount of power applied to the aerosol generation unit by further taking the first temperature information into consideration. Specifically, the control unit increases or decreases the amount of power applied to the aerosol generation unit based on the second temperature information, and the rate of increase or decrease of the amount of power is determined based on the first temperature information. For example, the rate of increase of the amount of power when the first temperature information is equal to or greater than a predetermined critical temperature is preset to be smaller than the rate of increase of the amount of power when the first temperature information is below the predetermined critical temperature. Or, the rate of decrease of the amount of power when the first temperature information is equal to or greater than the predetermined critical temperature is preset to be larger than the rate of decrease of the amount of power when the first temperature information is below the predetermined critical temperature. In this case, the control unit increases or decreases the amount of power more slowly or more quickly when the first temperature information is equal to or greater than the predetermined critical temperature, thereby delaying the temperature of the display module from increasing to the maximum allowable temperature as much as possible. Here, the predetermined critical temperature is set to a temperature that is lower than the maximum allowable temperature but at which the first temperature information (or the temperature of the display module) is likely to reach the maximum allowable temperature within a predefined first time interval due to the temperature of the susceptor. For example, the first time interval is determined based on an average operating time or a predefined duration from when a stick is accommodated in the aerosol generating unit until the generation of the aerosol ends.

[0771] Alternatively, if the first temperature information is equal to or greater than the predetermined critical temperature, the control unit adjusts the second critical temperature based on the first temperature information. For example, if the first temperature information is less than the predetermined critical temperature, the control unit increases the temperature of the aerosol generation unit to the second critical temperature, but if the first temperature information is equal to or greater than the predetermined critical temperature, the control unit increases the temperature of the aerosol generation unit only to a third critical temperature lower than the second critical temperature. For example, such adjustment of the second critical temperature based on the first temperature information is determined by the first temperature information obtained when the storage of the stick is detected.

[0772] Next, the control unit determines or judges whether at least one of the preset conditions is satisfied (S6305). Here, the preset conditions include the counter value reaching 0, a preset time elapses after the stick is placed in the aerosol generation unit, the stick is removed from the aerosol generation unit, or the first temperature information being equal to or higher than a predetermined critical temperature. Here, the predetermined critical temperature is predetermined to be lower than the maximum allowable temperature but higher than the predetermined critical temperature. If the preset condition is not satisfied, the control unit can continue to control the power of the aerosol generation unit based on the second temperature information.

[0773] The control unit stops applying power to the aerosol generating unit when at least one of the preset conditions is satisfied (S6307). At this time, the control unit controls the sensing unit to cut off electrical connection for measuring second temperature information of the aerosol generating unit. Alternatively, as described above, the control unit resets the counter value of the counter when the preset conditions are satisfied.

[0774] 66 is a front view showing a mobile communication terminal in a state where the stick is not housed according to an embodiment of the present invention. Hereinafter, a description that overlaps with the above content will be omitted.

[0775] The mobile communication terminal includes a flexible display 7711 including an aerosol-generating unit 7200 and a first region 7712 in contact with a first surface of the aerosol-generating unit 7200 .

[0776] This figure is a front view showing a mobile communication terminal in a state where a stick (not shown) is not accommodated in the aerosol generating unit 7200. That is, since the stick is not accommodated in the aerosol generating unit 7200, the first region 7712 of the flexible display 7711 maintains a flat surface.

[0777] In one embodiment, at least one area of ​​the flexible display 7711 of the present invention is deformed into a flat or curved surface depending on whether a stick is contained in the aerosol generating unit 7200 or not.

[0778] To this end, the flexible display 7711 includes multiple layers that allow at least one region to be transformed into a flat or curved surface, as will be described in more detail below.

[0779] 67 is a front view showing a mobile communication terminal in a state where a stick is housed according to an embodiment of the present invention. Hereinafter, a description that overlaps with the above content will be omitted.

[0780] The mobile communication terminal includes a flexible display 7711 including an aerosol-generating unit 7200 and an area 7712 in contact with a first surface of the aerosol-generating unit 7200. Here, the aerosol-generating unit 7200 is formed to have a first length h. Here, the first length h is determined based on the length of the stick 7100.

[0781] In this embodiment, a front view of a mobile communication terminal is shown in a state in which a stick 7100 is accommodated in an aerosol generating unit 7200. Here, the stick 7100 is merely an example, and any aerosol producing product capable of generating aerosol may be used.

[0782] That is, when the stick 7100 is accommodated in the aerosol generating unit 7200, at least a portion of one region of the flexible display 7711 is deformed into a curved surface. That is, the first region 7712 of the flexible display 7711 is deformed into a curved surface or a flat surface having various curvatures, unlike a conventional curved display that is maintained as a flat or flat surface. At this time, the curvature for forming the curved surface of the first region 7712 is characterized by being such that physical damage is not caused to the flexible display 7711.

[0783] Furthermore, since the length of the aerosol generation unit 7200 is the first length h, the flexible display 7711 forms a first region 7712 of the flexible display 7711 by the first length h.

[0784] Various configurations required for the first region 7712 of the flexible display 7711 to be deformed into a curved surface will be described in detail below.

[0785] 68 is a top view showing a mobile communication terminal in a state where the stick is not housed according to an embodiment of the present invention. Hereinafter, a description that overlaps with the above content will be omitted.

[0786] Here, the first area 7712, the second area 7713, and the third area 7714 contact the support member in the direction A, and contact the panel displaying an image in the direction A'. In this case, the direction A indicates the rear side of the mobile communication terminal, and the direction A' indicates the front side of the mobile communication terminal. This also applies to the following figures.

[0787] In one embodiment, when no stick is contained in the aerosol generating unit 7200, the first surface 7201 of the aerosol generating unit 7200 can remain flat.

[0788] For this purpose, the first surface 7201 (dotted line) of the aerosol generating unit 7200 is formed of a ductile material (for example, a ductile plastic or polymer) or a flexible material. In this case, the first surface 7201 of the aerosol generating unit 7200 is formed of a different material from the other surfaces except for the first surface 7201. As a result, when a stick is inserted, the other surfaces except for the first surface 7201 maintain a fixed shape, and the first surface 7201 changes from a flat surface to a curved surface. An embodiment in which the first surface 7201 of the aerosol generating unit 7200 is transformed into a curved surface will be described in detail below.

[0789] Similarly, a first region 7712 (dotted line), a second region 7713, and a third region 7714 of the flexible display 7711 can remain flat due to the stick not being housed therein.

[0790] The mobile communication terminal of the present invention includes a flexible display 7711 including an aerosol-generating unit 7200 and a first region 7712 in contact with a first surface 7201 of the aerosol-generating unit 7200 .

[0791] The aerosol generating unit 7200 accommodates a stick (not shown) that generates aerosol. In one embodiment, a controller of the mobile communication terminal detects that the stick is accommodated in the aerosol generating unit 7200. At this time, the first region 7712 is deformed into a curved shape as the stick is accommodated in the aerosol generating unit 7200. In one embodiment, when the stick is accommodated in the flexible display 7711, the first region 7712 is deformed into a curved shape due to the pressure of the stick. This will be described in detail below.

[0792] On the other hand, the second region 7713 and the third region 7714 that are not in contact with the first surface 7201 of the aerosol generation portion 7200 remain flat.

[0793] Below, we will explain in detail the flexible display 7711, which is composed of multiple layers, because when the stick is contained in the aerosol generating unit 7200, at least a portion of the first region 7712 in contact with the first surface 7201 is deformed into a curved surface.

[0794] 69 is a plan view showing a mobile communication terminal in a state where the stick is not housed according to an embodiment of the present invention. Hereinafter, a description that overlaps with the above content will be omitted.

[0795] In one embodiment, the aerosol-generating unit 7200 includes a first hinge unit 7202, a second hinge unit 7203, a first portion 7204, a second portion 7205, and a third portion 7206. Here, the first hinge unit 7202 and the second hinge unit 7203 are formed symmetrically corresponding to the aerosol-generating unit 7200. The first portion 7204 corresponds to a member portion located on a surface of the aerosol-generating unit 7200 that contacts a support member of the mobile communication terminal, and the second portion 7205 and the third portion 7206 correspond to member portions located on a surface of the aerosol-generating unit 7200 that contacts a flexible display 7711 of the mobile communication terminal.

[0796] The first hinge portion 7202 is formed with a structure that connects the first part 7204 and the second part 7205 of the aerosol generation portion 7200, and the second hinge portion 7203 is formed with a structure that connects the first part 7204 and the third part 7206 of the aerosol generation portion 7200.

[0797] In one embodiment, first hinge portion 7202 folds and unfolds second portion 7205, and second hinge portion 7203 folds and unfolds third portion 7206. To this end, first hinge portion 7202 and second hinge portion 7203 are fixed to first portion 7204. Figure 70 shows second portion 7205 and third portion 7206 in a folded state.

[0798] 70 is a plan view showing a mobile communication terminal in a state where a stick is accommodated according to an embodiment of the present invention. Hereinafter, a description that overlaps with the above content will be omitted.

[0799] 70, when a stick (not shown) is inserted, the second part 7205 and the third part 7206 connected to the first hinge part 7202 and the second hinge part 7203 of the aerosol-generating part 7200, respectively, are deformed into an unfolded shape. At this time, the first part 7204 of the aerosol-generating part 7200 can be maintained in a fixed state because it is the part that abuts against the support member (rear surface) of the mobile communication terminal.

[0800] At this time, when the user physically inserts the stick into the aerosol generating unit 7200, the second part 7205 connected to the first hinge part 7202 is unfolded, and the third part 7206 connected to the second hinge part 7203 is unfolded. In another embodiment, as shown in the drawings described later, the second part 7205 connected to the first hinge part 7202 is unfolded and the third part 7206 connected to the second hinge part 7203 is unfolded under the control of the mobile communication terminal.

[0801] For this reason, the first portion 7204, the second portion 7205, and the third portion 7206 of the aerosol-generating portion 7200 are formed of different materials. For example, the first portion 7204, the second portion 7205, and the third portion 7206 of the aerosol-generating portion 7200 are formed of plastic, metal, ceramic, or the like.

[0802] This causes the second part 7205 connected to the first hinge part 7202 to unfold, and the third part 7206 connected to the second hinge part 7203 to unfold, thereby allowing the aerosol generating part 7200 to secure space large enough to accommodate the stick.

[0803] That is, the angle at which the second section 7205 is deployed by the first hinge section 7202 and the angle at which the third section 7206 is deployed by the second hinge section 7203 corresponds to the angle at which the stick is stored.

[0804] In addition, as the second part 7205 and the third part 7206 of the aerosol generating unit 7200 are unfolded, the first region 7712 of the flexible display 7711 expands toward the front of the mobile communication terminal, which will be described in detail with reference to other figures.

[0805] 71 is a diagram illustrating the operation of a mobile communication terminal in a stick storage mode according to an embodiment of the present invention. Hereinafter, a description that overlaps with the above description will be omitted.

[0806] The mobile communication terminal outputs various applications on the flexible display 7711. In one embodiment, the mobile communication terminal outputs an application icon 7715 related to the stick storage mode.

[0807] Here, the stick storage mode corresponds to a mode in which a user generates aerosol using the aerosol generating unit 7200 included in the mobile communication terminal, and uses the mobile communication terminal as an electronic cigarette.

[0808] To this end, the mobile communication terminal outputs an application icon 7715 for providing the stick accommodation mode. In one embodiment, the mobile communication terminal receives a control signal 7716 for selecting an application icon 7715 associated with the stick accommodation mode. For example, the control signal 7716 corresponds to a control signal generated when a user touches an application icon 7715 displayed on the flexible display 7711 of the mobile communication terminal.

[0809] By receiving a control signal for selecting an application icon 7715 related to the stick accommodation mode, the mobile communication terminal can change the aerosol generating unit 7200 into a shape that can accommodate the stick.

[0810] At this time, the method for transforming the aerosol generating unit 7200 into a shape that can be housed in a stick may be referred to the above-mentioned drawings. Also, as the aerosol generating unit 7200 transforms into a shape that can be housed in a stick, the first region 7712 of the flexible display 7711 is bent or folded. This will be described below with reference to the drawings.

[0811] 72 is a diagram illustrating a first area of ​​a flexible display of a mobile communication terminal according to an embodiment of the present invention. Hereinafter, a description that overlaps with the above description will be omitted.

[0812] The flexible display 7711 of the present invention includes a cover window 7811, a polarizing panel 7812, a touch panel 7813, a flexible display panel 7814 that displays an image, and a base film 7815 disposed on the outside of the flexible display panel 7814. For ease of explanation, a first region 7712 that can be transformed into a flat or curved surface of the flexible display 7711 will be described as an example. Of course, a second region (not shown) and a third region (not shown) of the flexible display 7711 also have the same configuration. However, the first region 7712 that can be transformed into a flat or curved surface and the second and third regions that maintain a flat surface may be formed in different shapes or have different structures from the multiple layers included in the first region 7712.

[0813] Each layer of the first area 7712 of the flexible display 7711 according to one embodiment will now be described.

[0814] The flexible display 7711 is formed by stacking multiple layers, each of which is included in a first region 7712, a second region, and a third region.

[0815] More specifically, the cover window 7811 is disposed in front of the flexible display 7711 (direction A') and can protect the flexible display 7711 from external impact. The cover window 7811 includes a material that has physical flexibility. The cover window 7811 also includes a transparent material that has high light transmittance.

[0816] In one embodiment, the cover window 7811 included in the first region 7712 of the flexible display 7711 and the cover window 7811 included in the second region or the third region are formed of different materials. In one embodiment, the cover window 7811 included in the second region or the third region is formed of a rigid material, and the cover window 7811 included in the first region 7712 is formed of a relatively ductile material. For this reason, the cover window 7811 included in the second region or the third region requires greater mechanical rigidity than the cover window 7811 included in the first region 7712, and therefore preferably includes an additional window layer.

[0817] In particular, since the second or third region is further exposed to the front surface of the mobile communication terminal, the cover window 7811 included in the second or third region may include multiple sub-layers to ensure reliability such as impact resistance. In one embodiment, the cover window 7811 includes a double cover window.

[0818] On the other hand, the cover window 7811 included in the first region 7712 is formed thinner or includes fewer layers than the second or third region due to the flexibility of the first region 7712 of the flexible display 7711.

[0819] The polarizing panel 7812 is bonded onto the touch panel 7813. The polarizing panel 7812 can prevent external light reflection to ensure black visibility of the flexible display 7711. For example, by preventing reflection of light incident through a cover window 7811 disposed on the polarizing panel 7813, the user's visibility can be improved.

[0820] In one embodiment, the polarizing panel 7812 includes a polyethylene terephthalate (PET) film, a tri-acetyl cellulose (TAC) film, a cyclic olefin polymer (COP) film, or a polyvinyl alcohol (PVA) film. To ensure the flexibility of the flexible display 7711 according to another embodiment, the polarizing panel 7812 is formed of a thin film, unlike the polarizing layer of a conventional display. The polarizing panel 7812 is also disposed between the touch panel 7813 and the cover window 7811.

[0821] The touch panel 7813 is disposed between the polarizing panel 7812 and the flexible display panel 7814. In one embodiment, the touch panel 7813 is formed to have a plurality of touch electrodes arranged thereon. The touch electrodes are controlled by a touch sensor IC, and detect touch input or hover input at a predetermined position by, for example, measuring a change in a signal (e.g., voltage, light intensity, resistance, or charge amount) at a predetermined position on the flexible display 7711, and provide information (e.g., position, area, pressure, or time) related to the detected touch input or hover input to a controller of the mobile communication terminal. In one embodiment, at least a portion of the touch panel 7813 (e.g., the touch sensor IC) is included as part of a display driver IC, or the display, or as part of another component (e.g., an auxiliary processor) outside the display.

[0822] In one embodiment, the touch panel 7813 may be formed of a thin film, on which a thin film touch electrode is formed.

[0823] The flexible display panel 7814 may be a liquid crystal display (LCD) panel, a light emitting diode (LED) display panel, an organic light emitting diode (OLED) display panel, a microelectromechanical system (MEMS) display panel, or an electronic paper display panel. For example, it may have an organic light emitting diode (OLED) structure. The organic light emitting diode panel has an organic light emitting layer disposed between an upper substrate and a lower substrate. A polarizing panel 7812 is disposed on the upper substrate, which is the light emitting side. The flexible display 7711 further includes a touch panel 7813 as an input means.

[0824] The base film 7815 is disposed on the rear surface of the flexible display panel 7814 and can protect the flexible display panel 7814. In this case, the base film 7815 is made of a flexible material (for example, PI).

[0825] In one embodiment, the base film 7815 is made of a flexible material. A typical display includes a base substrate made of glass that is disposed under the display panel. Glass is not suitable for displays that are subject to constant bending or flexing, such as the flexible display 7711 according to various embodiments. Therefore, the base film 7815 includes an embossing layer and / or a cushion layer. However, depending on the flexibility of the flexible display 7711, the embossing layer and / or cushion layer may be omitted.

[0826] In one embodiment, the cover window 7811, the polarizer panel 7812, the touch panel 7813, the flexible display panel 7814 and the base film 7815 are adhered to each other by an optically clear adhesive layer (OCA) (not shown).

[0827] In one embodiment, the flexible display 7711 further comprises various optical panels or optical films.

[0828] The first region 7712 of the flexible display 7711 formed with this structure is deformed into a flat or curved surface depending on whether or not a stick of the aerosol generating unit (not shown) is accommodated.

[0829] 73 is a diagram illustrating a first area of ​​a flexible display of a mobile communication terminal according to another embodiment of the present invention. Hereinafter, a description that overlaps with the above description will be omitted.

[0830] The multiple layers included in the first region 7712 of the flexible display 7711 are shown forming a curvature as the stick is housed in the aerosol generating section.

[0831] As a result, the cover window 7811, the polarizing panel 7812, the touch panel 7813, the display panel 7814, and the base film 7815 included in the first region 7712 are deformed based on the stick shape of the aerosol generating unit (not shown).

[0832] More specifically, the curvature formed by the cover window 7811, polarizing panel 7812, touch panel 7813, display panel 7814, and base film 7815 included in the first region 7712 is determined based on the stick shape. For example, if the stick shape is a perfect circle, each component module included in the first region 7712 is deformed to a curvature that surrounds a circular stick. If the stick shape is an ellipse, each component module included in the first region 7712 is deformed to a curvature that surrounds an elliptical stick. In this case, each component module included in the first region 7712 forms a curvature that surrounds the stick, but can maintain a minimum curvature to prevent damage to each component module.

[0833] 74 is a diagram illustrating a flexible display of a mobile communication terminal according to an embodiment of the present invention. Hereinafter, a description that overlaps with the above description will be omitted.

[0834] As described above, the flexible display 7711 is composed of multiple layers, among which the flexible display panel 7814 includes a substrate 7911, a pixel array 7912 formed on the substrate 7911, and a thin film encapsulation (TFE) layer 7913 that encapsulates the pixel array 7912.

[0835] The pixel array 7912 includes a plurality of pixels, each including a light-emitting diode (LED). The light-emitting diodes are electrically connected to a display driver circuit and can emit light in response to an electrical signal. The display driver circuit includes a driver IC, which transmits power or video signals to the light-emitting diodes via conductive lines.

[0836] A thin film encapsulation layer 7913 for encapsulating the plurality of light emitting diodes is formed on the pixel array 7912. Because the OLED element is highly susceptible to moisture and oxygen, the thin film encapsulation layer 7913 serves to prevent water and oxygen from permeating into the light emitting diodes. The thin film encapsulation layer 7913 can protect the plurality of light emitting diodes from moisture or oxygen by forming a plurality of organic or inorganic layers. In this case, the thin film encapsulation layer 7913 may have a structure in which composite layers including organic layers and inorganic layers are alternately stacked. The thin film encapsulation layer 7913 may further include a thin film evaporation film.

[0837] In one embodiment, the pixel array 7912 includes sub-pixels, each of which includes an anode electrode formed on the substrate 7911, an organic material capable of expressing R, G, and B formed on the anode electrode, and a cathode electrode formed on the organic material. Here, the anode electrode is electrically connected to the flexible display panel 7814, and may be formed in multiple layers or in a single layer.

[0838] A thin film encapsulation layer 7913 covers the cathode electrode. The cathode electrode may be electrically connected to the pixels. The cathode electrode is configured in the form of a layer disposed on top of a plurality of pixels. The cathode electrode is disposed on top of the pixel array 7912.

[0839] In one embodiment, the flexible display 7711 includes a first region 7712, a second region 7713, and a third region 7714, and Figure 72 shows multiple layers included in the second region 7713 and the third region 7714 of the flexible display 7711. That is, the structures, shapes, or forms of the multiple layers included in the first region 7712, which can be deformed into a curved surface, and the second region 7713 and the third region 7714, which remain flat, may be different.

[0840] Unlike the first region 7712, the base film 7815 in the second region 7713 or the third region 7714 is formed to be flat.

[0841] The touch panel 7813 in the second region 7713 or the third region 7714 includes a plurality of touch electrodes arranged on a substrate 7911 and a touch panel circuit electrically connected to each touch electrode for controlling the touch electrodes. The touch panel circuit formed on the touch panel 7813 includes conductive lines 7914 and 7915 extending in the column and row directions of the touch panel 7813. The conductive lines are formed of a conductive pattern printed on the substrate 7911.

[0842] In this case, the conductors include a first conductor 7914 which is a conductor in the column direction and a second conductor 7915 which is a conductor in the row direction. In addition, one of the first conductor and the second conductor is connected to a receiving electrode, and the other is connected to a transmitting electrode. The first conductor and the second conductor are electrically shorted.

[0843] 75 is a diagram illustrating a flexible display of a mobile communication terminal according to an embodiment of the present invention. Hereinafter, a description that overlaps with the above description will be omitted.

[0844] This diagram shows multiple layers included in a first region 7712 of a flexible display 7711. Therefore, there are differences in some layers compared to the second region 7713 and the third region 7714 described above. The following description will focus on the differences from the above-described configuration.

[0845] When the thin film encapsulation layer 7913 described in the second region 7713 and the third region 7714 is provided to cover the pixel array 7912 included in the first region 7712, cracks may occur in the continuously bending or flexing thin film encapsulation layer 7913. If cracks occur in the thin film encapsulation layer 7913, black spots will appear on the display panel 7814. To prevent this, the thin film encapsulation layer 7913 included in the first region 7712 is formed to independently encapsulate some of the light emitting diodes of the plurality of light emitting diodes.

[0846] More specifically, the encapsulating members of the thin film encapsulation layer 7913 are spaced apart from one another, and an adhesive having a high elastic modulus and a low modulus is filled between each encapsulating member. To this end, the encapsulating member encapsulates one or more capsules in a trapezoidal shape. The encapsulating member individually encapsulates one or more pixels, minimizing stress applied to the thin film encapsulation layer 7913 and preventing cracks from occurring in the layer. That is, the encapsulating member can independently encapsulate the organic material and the cathode electrode. This allows the flexible display 7711 to be smoothly bent without damaging the thin film encapsulation layer 7913.

[0847] Unlike the second region 7713 and the third region 7714, the base film 7815 in the first region 7712 has grooves formed in a direction perpendicular to the extension direction of the base film 7815. Here, the grooves formed in the base film 7815 are formed perpendicular to the bending direction of the flexible display 7711. This makes it possible to prevent damage to the base film 7815 when the first region 7712 bends or flexes.

[0848] The touch panel 7813 in the first region 7712 includes a plurality of touch electrodes arranged on a substrate 7911 and a touch panel circuit electrically connected to control each touch electrode. Similarly, the touch panel circuit formed on the touch panel 7813 includes conductive lines 7914 and 7915 extending in the column and row directions of the touch panel 7813. However, the conductive lines included in the first region 7712 may have a different structure from the conductive lines 7914 and 7915 included in the second region 7713 or the third region 7714.

[0849] In one embodiment, the second conductive line 7915 included in the first region 7712 is formed in a zigzag conductive pattern, while the first conductive line 7914 is formed in a straight line, similar to the second region 7713 or the third region 7714.

[0850] Considering the bending direction of the first region 7712, when the first conducting wire 7914 is bent perpendicular to the bending direction, a relatively small stress can act in the longitudinal direction of the first conducting wire 7914. Therefore, the first conducting wire 7914 is less likely to be damaged or short-circuited due to bending.

[0851] On the other hand, the second conductive wire 7915 formed in parallel in the bending direction generates a relatively large stress in the length direction of the second conductive wire 7915. This acts as stress on the conductive wires formed on the substrate 7911, and the second conductive wire 7915 may be short-circuited or damaged. Therefore, the second conductive wire 7915 is formed to have a zigzag pattern. This allows the stress acting on the second conductive wire 7915 in the bending direction to be effectively dispersed.

[0852] 76 is a diagram showing a pressure sensor array of a flexible display according to an embodiment of the present invention. Hereinafter, a description that overlaps with the above content will be omitted.

[0853] In particular, a pressure sensor array 7921 included in the second region 7713 or the third region 7714 of a flexible display 7711 according to one embodiment of the present invention will be described.

[0854] The pressure sensor array 7921 includes at least one pressure sensor 7922 arranged on an array and wiring for electrically connecting the pressure sensors 7922 together.

[0855] However, in one embodiment, the pressure sensor array 7921 can be omitted from the second region 7713 or the third region 7714. This is because the first region 7712 needs to sense pressure due to the insertion of a stick, but the second region 7713 or the third region 7714 does not need to sense pressure.

[0856] 77 is a diagram showing a pressure sensor array of a flexible display according to an embodiment of the present invention. Hereinafter, a description that overlaps with the above description will be omitted.

[0857] In particular, a pressure sensor array 7921 included in a first region 7712 of a flexible display 7711 according to one embodiment of the present invention will be described.

[0858] The pressure sensor array 7921 included in the first region 7712 includes a plurality of grooves 7923 .

[0859] Here, the plurality of grooves 7923 are formed between the pressure sensors 7922 and extend in a direction perpendicular to the bending direction, or in directions parallel and perpendicular to the bending direction. In particular, the grooves 7923 formed in a direction perpendicular to the bending or bending direction of the flexible display 7711 can disperse stress acting on the base film 7815.

[0860] In one embodiment, the pressure sensor array 7921 detects pressure applied to the first region 7712 of the mobile communication terminal. For example, when a user inserts a stick into the aerosol generating unit, the pressure sensor array 7921 detects the pressure applied to the first region 7712. As a result, when the stick is accommodated in the flexible display 7711, the first region 7712 is deformed into a curved shape due to the pressure.
