Description

Technical Field

[0001] The following disclosure relates to a mobile communication terminal and a control method thereof.

[0002] More specifically, the following disclosure relates to a mobile communication terminal capable of generating aerosol and a control method thereof. Background Art

[0003] In a conventional electrically driven aerosol generating device, a user inserts a cigarette stick into a separate device equipped with a heating element and then inhales the aerosol generated by the heating of the cigarette stick through the mouth.

[0004] With the advancement of technology, more and more aerosol generating devices of this type are equipped with communication modules to communicate with mobile terminals.

[0005] In addition, conventional aerosol generating devices are provided in communication terminals such as mobile phones (see, for example, U.S. Pat. No. 9,894,938). The aerosol generator provided in the communication terminal is powered by a power supply unit (battery, etc.) provided inside the communication terminal to heat the aerosol generating substance.

[0006] However, this structure is merely a shared power supply device and does not provide the functional or structural solution that can actually be achieved by a single combined device.

[0007] For example, if the aerosol generating device and the mobile communication terminal are provided as a single device, multiple components must be arranged within the space of the device, which may result in a very narrow installation space and severe interference between components as the spacing between components decreases.

[0008] This can result in poor performance and component (display, processor, memory, etc.) degradation.

[0009] If the aerosol generating device and the mobile communication terminal are provided as a single device, the cigarette rod insertion portion may protrude from the mobile communication terminal or increase the thickness of the device, thereby causing inconvenience in portability.

[0010] Furthermore, if the aerosol generating device and the mobile communication device are provided as a single device, droplets or the like may be generated on the mobile communication device, causing adhesion of other components.

[0011] Furthermore, residues of aerosol-generating substances adhering to the heating portion of the aerosol-generating device may cause hygiene problems and may also be inconvenient because of the need for cleaning.

[0012] If the aerosol generating device and the mobile communication terminal are provided as a single device, it may be difficult to measure and control the temperature in the aerosol generating device depending on how the aerosol generating device and the mobile communication terminal are connected. Therefore, device control such as proportional-integral-derivative (PID) control may not be possible. Summary of the invention

[0118] The aerosol generator 200 may receive power input from the power supply unit 300 and may generate aerosol for the user to experience under the control of the controller 200 .

[0119] The aerosol generator 200 may contain an aerosol generating article or a cigarette. It is envisioned here that the cigarette is in the form of a cigarette rod, but the concept of the present disclosure is not necessarily limited thereto. The internal structure of the cigarette rod may be different in different embodiments, and its detailed embodiments will be disclosed below.

[0120] The aerosol generator 200 has a housing space or an insertion space and can house an aerosol generating article, a cigarette cartridge or a cigarette. The aerosol generator 200 can have various shapes, but will be described below taking a tubular shape as an example.

[0121] The aerosol generator 200 may include a heater or heating portion in various ways to heat the aerosol generating article or cigarette. The heater may include multiple components. In this case, the heater is referred to as a heater assembly or heating assembly.

[0122] The aerosol generator 200 may heat the aerosol generating article or cigarette using one of a variety of heating methods. For example, the aerosol generator 200 may heat a susceptor in the housing space using a magnetic field from a coil embedded in a housing of the housing space, thereby heating the aerosol generating article, or may directly or inductively heat the aerosol generating article using, for example, a heating pattern element on the housing, a heating element or a needle in the housing.

Voice data or image data collected by the input unit 600 may be analyzed and processed into a user's control command.

[0142] The camera module 610 processes an image frame such as a still image or a moving image obtained by the image sensor. The processed image frame may be displayed on the display module 710 of the output unit 700 or stored in the storage 800.

For example, the haptic module may synthesize and output different vibrations or output vibrations in sequence.

[0151] When the output unit 700 includes an optical output unit, the optical output unit uses light from a light source of the mobile communication terminal to output a signal to indicate the occurrence of an event. Examples of events occurring on the mobile communication terminal may be message reception, call signal reception, missed calls, alarms, schedule notifications, email reception, and information reception through an application.

[0152] The storage unit 800 stores data supporting various functions of the mobile communication terminal. The storage unit 800 can store applications (or applications) executed on the mobile communication terminal, as well as data and instructions for operating the mobile communication terminal. At least some of these applications can be downloaded from an external server via wireless communication. In addition, at least some of these applications exist when the mobile communication terminal leaves the factory to implement the basic functions of the mobile communication terminal (e.g., receiving calls, making calls, receiving messages, and sending messages). The application can be stored in the storage unit 800 and installed on the mobile communication terminal, and executed by the controller 100 to implement the operation (or function) of the mobile communication terminal.

[0153] The interface 900 is used as a channel for various types of external devices to be connected to the mobile communication terminal.

When an external device is connected to the interface 900, the mobile communication terminal can perform appropriate control related to the connected external device.

[0154] In addition to the operation related to the application program, the controller 100 generally controls the overall operation of the mobile communication terminal. The controller 100 can provide or process appropriate information or functions for the user in the following ways: by processing the signals, data, information, etc. input or output by the above components, or by executing the application program stored in the storage unit 800.

In addition, the operation, control or control method of the mobile communication terminal may be implemented by executing at least one application stored in the memory 800.

[0157] The above modules represent a logical structure. In terms of physical structure, two or more modules can constitute one physical structure, or one module can include two or more physical structures.

[0177] In this case, a structure for preventing the performance of the GPS antenna from being degraded may be required, and its detailed implementation will be disclosed below.

[0178] Figure 3 is an exploded view of an embodiment of a mobile communication terminal.

[0179] The exploded view of the mobile communication terminal includes a body 1110 and a rear frame 1210. The rear frame 1210 is separable from the camera frame 1220.

[0180] The camera frame 1220 may provide a frame in which a camera module array part including a first camera module 1221 , a second camera module 1225 , and a third camera module 1227 is disposed.

[0181] An antenna module 1310 for wireless communication may be disposed on a lower side of the body 1110 .

[0182] The body 1110 may include a circuit board group including a first circuit board 1410 , a second circuit board 1420 , a third circuit board 1430 , and a fourth circuit board 1440 .

[0183] Each circuit board may include various chips on both surfaces of the circuit board. These chips perform control functions. For example, the first circuit board 1410 may include a front-end chip for communication and an audio amplifier chip. The second circuit board 1420 may include a mobile processor, a communication modulator, a power control chip, and a memory.

[0184] The third circuit board 1430 may include a camera control module for controlling the camera module array part, and the fourth circuit board 1440 may have a laser control chip attached thereto for the camera module array part.

[0185] The loop coil module 1730 may include a coil for short-range radio antenna communication and wireless charging and a control circuit thereof.

[0186] The fifth circuit board 1710 may include a circuit for audio output. A battery module 1910 that supplies power to the circuit may be included in the body 1110 .

[0187] The aerosol generator 1100 may be disposed at the top of the body 1110 and electrically connected to the circuit board group of the body 1110. The aerosol generator 1100 may accommodate a cigarette rod S including an aerosol generating article or a cigarette.

[0188] Although the aerosol generator 1110 and the smoke rod are shown as cylindrical in this example, they may be implemented in different ways according to different embodiments. In the embodiments described below, the aerosol generator 1110 and the smoke rod are shown as cylindrical for simplicity.

[0189] The implementation of the aerosol generator for the mobile communication terminal will be disclosed in detail below.

[0190] The disclosed aerosol generator is used to generate aerosol by electrically heating a cigarette accommodated in an inner space of the aerosol generator.

[0191] The aerosol generator 200 may include a heater. In one embodiment, the heater may be a resistive heater. For example, the heater may include an electrically conductive track, and the heater may be heated when current flows through the conductive track.

[0192] The heater may include a tubular heating element, a plate heating element, a needle heating element or a rod heating element, and may heat the inside or outside of the cigarette according to the shape of the heating element. Related embodiments will be described in detail below.

[0193] The cigarette may include a tobacco rod and a filter rod. The tobacco rod may be made of a thin sheet, may be made of a linear portion, or may be made of shredded tobacco sheets. In addition, the tobacco rod may be surrounded by a heat conductive material.

[0194] For example, the thermally conductive material may be, but is not limited to, a metal foil such as aluminum foil.

[0195] The filter rod may be a cellulose acetate filter. The filter rod may include at least one section. For example, the filter rod may include a first section for cooling the aerosol and a second section for filtering a predetermined component contained in the aerosol.

[0196] In another embodiment, the aerosol generator may generate the aerosol using a cartridge holding an aerosol generating substance.

[0197] The aerosol generator may include a cartridge configured to hold an aerosol generating substance and a body supporting the cartridge. The cartridge may be removably connected to a mobile communication terminal or an aerosol generator, but is not limited thereto. The cartridge may be integrally formed or connected to a mobile communication terminal or an aerosol generator, and may be fixed so that the user cannot remove it. The cartridge may be mounted to the body while containing an aerosol generating substance. However, embodiments are not limited thereto. The aerosol generating substance may be injected into the cartridge while the cartridge is connected to a mobile communication terminal or an aerosol generator.

[0198] The cigarette cartridge can hold an aerosol-generating substance in any of the following states: for example, a liquid state, a solid state, a gaseous state, and a gel state. The aerosol-generating substance can include a liquid component. For example, the liquid component can be a liquid containing a tobacco-containing substance that includes a volatile tobacco flavor component, or can be a liquid containing a non-tobacco substance.

[0199] The cartridge is operated by an electrical signal or a wireless signal sent from the body, thereby converting the phase of the aerosol-generating substance in the cartridge into a gas phase to generate an aerosol. Aerosol may refer to a gas containing a mixture of vaporized particles generated by the aerosol-generating substance and air.

[0200] In another embodiment, an aerosol can be generated by heating an aerosol mobile communication terminal or an aerosol generator and a liquid component. The generated aerosol can be delivered to a user through a cigarette. That is, the aerosol generated from the liquid component can move along an airflow channel in the aerosol generator. The airflow channel can be configured to allow the aerosol to pass through the cigarette and be delivered to the user.

[0201] In another embodiment, aerosol may be generated from an aerosol generating substance using an aerosol mobile communication terminal or an aerosol generator and an ultrasonic vibration method. Here, the ultrasonic vibration method may refer to a method of generating aerosol by atomizing an aerosol generating substance through ultrasonic vibration generated by a vibrator.

[0202] The aerosol generator may include a vibrator, and may generate short-period vibrations through the vibrator to atomize the aerosol generating substance. The vibration generated from the vibrator may be ultrasonic vibration, and the frequency band of the ultrasonic vibration may be from about 100 kHz to about 3.5 MHz, but is not limited thereto.

[0203] The aerosol generator may further comprise a core that absorbs the aerosol generating substance.For example, the core may be arranged to surround at least one region of the vibrator or to be in contact with at least one region of the vibrator.

[0204] When a voltage (e.g., an AC voltage) is applied to the vibrator, the vibrator may generate heat and / or ultrasonic vibrations. The heat and / or ultrasonic vibrations generated from the vibrator may be transferred to the aerosol-generating substance absorbed by the core. The aerosol-generating substance absorbed into the core may be converted into a gas phase by the heat and / or ultrasonic vibrations transferred from the vibrator. As a result, an aerosol may be generated.

[0205] For example, the viscosity of the aerosol generating substance absorbed into the core may be reduced due to the heat generated by the vibrator. The aerosol generating substance whose viscosity is reduced due to the ultrasonic vibration generated by the vibrator may be converted into fine particles, thereby generating aerosol. However, embodiments are not limited thereto.

[0206] In another embodiment, the aerosol generator may generate the aerosol by heating an aerosol-generating article housed in the aerosol generator by induction heating.

[0207] The aerosol generator may include a susceptor and a coil. In one embodiment, the coil may apply a magnetic field to the susceptor. When power is supplied from the aerosol generator to the coil, a magnetic field may be formed inside the coil. In one embodiment, the susceptor may be a magnetic component that generates heat by an external magnetic field. When the susceptor is arranged inside the coil and a magnetic field is applied, the aerosol generating article may be heated by generating heat. In addition, optionally, the susceptor may be arranged in the aerosol generating article.

[0208] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings to facilitate implementation by those skilled in the art.

[0209] Disclosed examples include a heater that heats an aerosol-generating substance according to a non-contact, external induction method.

[0210] Figure 4 is a cross-sectional view of one embodiment of an aerosol generating module taken along one direction.

[0211] The aerosol generator 200 may include a heater capable of heating the aerosol-generating article when the aerosol-generating article is inserted into the tubular interior space using one of several methods.

[0212] Here, the aerosol generator 200 according to one embodiment may include an inner container 2200 , a first support portion 2210 , a second support portion 2220 , and a heater 2300 .

[0213] The inner container 2200 may be disposed in the inner space of the housing 2100. The inner container 2200 may include an accommodation space 2205 for accommodating the aerosol generating article 220.

[0214] The accommodating space 2205 can not only accommodate the aerosol generating article 220, but also serve as a passage for the flow of air from the outside. An internal passage 2202 can be formed between the internal container 2200 and the heater 2300 to allow the air introduced into the accommodating space 2205 to flow toward the second support portion 2220 through the inflow channel (not shown) of the first support portion 2210. The air introduced into the accommodating space 2205 can flow along the internal passage 2202 and reach the second support portion 2220.

[0215] The first support portion 2210 may be disposed at the entrance of the accommodation space 2205 to support at least a portion of the aerosol generating article 220 accommodated in the accommodation space 2205. In addition, the first support portion 2210 may allow air existing outside the aerosol generator 200 to flow into the accommodation space 2205.

[0216] The first support portion 2210 may include a support member (not shown) arranged to support at least a portion of the aerosol generating substance, and an inflow channel allowing air outside the aerosol generator 200 to flow into the accommodating space 2205 .

[0217] The first support portion 2210 may include a suction sensing hole 2211 leading to the suction sensor 2330. The suction sensing hole 2211 may be provided at a lower end portion of the suction sensor 2330, the lower end portion of the suction sensor 2330 being adjacent to the first support portion 2210. The air having passed through the inflow channel may flow into the suction sensor 2330 through the suction sensing hole 2211.

[0218] The suction sensing hole 2211 may become narrower as it extends toward the suction sensor 2330. However, the suction sensing hole 2211 is not limited to the above shape.

[0219] The second support portion 2220 may be disposed inside the accommodation space 2205 to support one end of the aerosol generating article 220. In addition, the second support portion 2220 may allow air present in the accommodation space 2205 to flow into the aerosol generating article 220.

[0220] The second support portion 2220 may include a delivery channel (not shown) that allows air in the accommodation space 2205 to flow into the aerosol-generating article through the delivery channel.

[0221] One end portion of the heater 2300 may be inserted into the second support portion 2220 . Therefore, the heater 2300 may be supported by the second support portion 2220 .

[0222] The coupling piece 2230 may be coupled to a lower end portion of the first supporting portion 2210 .

[0223] The coupling 2230 may include a first air hole (not shown) that allows air, having passed through the inflow channel of the first support portion 2210 , to flow into the accommodating space 2205 through the first air hole.

[0224] Once the coupling 2230 and the first support portion 2210 are coupled, a suction sensing passage 2301 may be formed between the upper end portion of the coupling 2230 and the first support portion 2210. The suction sensing passage 2301 may connect the inflow passage and the suction sensor 2330. Air having passed through the inflow passage of the first support portion 2210 may pass through the suction sensing passage 2301 and flow into the suction sensor 2330 adjacent to the first support portion 2210.

[0225] According to one embodiment, the air moving along the suction sensing passage 2301 may pass through the suction sensing hole 2211 of the first support portion 2210 and reach the suction sensor 2330 .

[0226] A portion of the coupling 2230 may surround the outer circumference of the inner container 2200. Other components outside the coupling 2230 may be arranged to contact a portion of the coupling 2230, thereby being supported by the coupling 2230.

[0227] Another portion of the coupling 2230 may be open. As a result, the aerosol generator 200 can ensure an internal space in which other components can be arranged.

[0228] The coupling 2230 may further include a guide 2331 to guide the insertion operation of the aerosol-generating article 220 .

[0229] To prevent the guide 2310 from obstructing the insertion of the aerosol-generating article 220 into the aerosol generator 200, at least a portion (eg, an upper portion) of the guide 2310 may be chamfered. The chamfered portion may be beveled or rounded.

[0230] In another example, the guide 2310 may support at least a portion of the outer circumferential surface of the aerosol-generating article 220 .

[0231] One end portion (eg, an upper end portion) of the inner container 2200 may be inserted into the coupling 2230. Thus, the inner container 2200 may be supported by the coupling 2230.

[0232] The outer container 2250 may be positioned to be spaced apart from the inner container 2200 so as to face the outside of the inner container 2200 .

[0233] The outer container 2250 may block the heat generated by the heater 2300 from being transferred to the outside. In order to improve the heat insulation efficiency, the outer container 2250 may include a double wall structure.

[0234] The outer container 2250 may include an inner wall 2251 facing the inner container 2200, an outer wall 2252 spaced apart from the inner wall 2251 and facing the outside of the outer container 2250, and an insulating space 2253 defined between the inner wall 2251 and the outer wall 2252. The insulating space 2253 may maintain a vacuum state to minimize heat transferred to the outside of the aerosol generator 200. "Vacuum" as used herein not only means a complete absence of air, but also includes a pressure lower than the ambient atmospheric pressure.

[0235] The outer container 2250 may include a through hole (not shown) at its lower end. One or more wires or magnetic field generators 2310 may extend to the outside of the outer container 2250 through the through hole in the outer container 2250 .

[0236] The inner container 2200 may include one or more supports 2201 in contact with the inner lower end of the outer container 2250. Due to these supports 2201, the inner container 2200 may be arranged to be spaced apart from the interior of the outer container 2250 and may be supported by the outer container 2250 in the longitudinal direction in which the aerosol generating article 220 is inserted.

[0237] The shielding portion 2260 may be disposed to surround at least a portion of the outer circumferential surface of the coupling 2230. The shielding portion 2260 may be disposed to contact at least a portion of the outer circumferential surface of the coupling 2230 to be supported by the coupling 2230.

[0238] The shielding portion 2260 may block the induced magnetic field generated inside the aerosol generator 200 from leaking to the outside of the aerosol generator 200 .

[0239] The shielding portion 2260 may include a wiring hole (not shown) opened in a radial direction of the accommodating space 2205 to allow the temperature sensing line 2320 to extend through the wiring hole.

[0240] The sealing portion 2270 may be provided at the outer lower end portion of the outer container 2250 to prevent liquid leakage. For example, the sealing portion 2270 may include an elastic material such as rubber or silicone.

[0241] The sealing portion 2270 may include a routing channel (not shown) through which one or more wires or magnetic field generators 2310 extend. The one or more wires or magnetic field generators 2310 may extend to the outside of the sealing portion 2270 through the routing channel in the sealing portion 2270.

[0242] The heater 2300 may be disposed inside the accommodation space 2205. The heater 2300 may accommodate at least a part of the aerosol-generating article 220 inserted into the housing 2100. The heater 2300 may support the circumferential surface of the aerosol-generating article 220 accommodated in the accommodation space 2205.

[0243] When powered, the heater 2300 generates heat. At least one area of the accommodated aerosol-generating article 220 may be heated by the heater 2300. The aerosol-generating article 220 may be heated so that the vaporized particles generated from the aerosol-generating article 220 are mixed with the air in the internal space of the housing 2100, thereby generating an aerosol.

[0244] According to one embodiment, the aerosol generator 200 may include a magnetic field generator 2310. In this case, the heater 2300 may be a susceptor.

[0245] The magnetic field generator 2310 may be coupled to the inner container 2200. For example, the magnetic field generator 2310 may be mounted on the outside of the inner container 2200.

[0246] The magnetic field generator 2310 may heat at least one area of the aerosol-generating article 220 accommodated in the accommodation space 2205 by induction heating.

[0247] The magnetic field generator 2310 may be arranged to surround the circumferential surface of the susceptor 2300, and may generate an induced magnetic field towards the susceptor 2300 using the power supplied from a battery (not shown).

[0248] The susceptor 2300 may be arranged to surround at least a part of the circumferential surface of the aerosol-generating article 220 accommodated in the accommodation space 2205. The susceptor 2300 may generate heat due to the alternating magnetic field generated by the magnetic field generator 2310, thereby heating the aerosol-generating article accommodated in the accommodation space 2205.

[0249] As another example of the heater 2300, the aerosol generator 200 may include a resistive heater. For example, the aerosol generator may include a film-type heater arranged to surround at least a part of the circumferential surface of the aerosol-generating article inserted into the housing 2100. The film-type heater may include conductive traces. When an electric current flows through the conductive traces, the film-type heater may generate heat to heat the aerosol-generating article inserted into the housing 2100.

[0250] As another example of the heater 2300, the aerosol generator 200 may include at least one of the following heaters capable of heating the interior of the aerosol generating article inserted into the housing 2100: a needle heater, a rod heater, and a tubular heater. For example, the above heater may be inserted into at least one region of the aerosol generating article to heat the interior of the aerosol generating article.

[0251] These examples are not limited by the specific implementation method of the heater 2300. The heater may be modified in various forms to heat the aerosol generating article 220 to a specified temperature. In the present disclosure, "specified temperature" may refer to a temperature at which the aerosol generating substance contained in the aerosol generating article 220 is heated to generate an aerosol. The specified temperature may be a temperature preset in the aerosol generator 200. Alternatively, the specified temperature may be changed due to the type of the aerosol generator 200 and / or user operation.

[0252] The temperature sensing line 2320 is an example of a temperature sensor. The temperature sensing line may be a thermocouple. As another example, the temperature sensing line may be a heat conducting line for transferring heat, and a sensor module that generates a signal according to a temperature change may be connected to the temperature sensing line.

[0253] A portion of the temperature sensing line 2320 may be connected to the heater 2300. The temperature sensing line 2320 may sense a temperature change of the heater 2300 when the heater 2300 operates.

[0254] The temperature sensing line 2320 may extend from the accommodation space 2205 to the outside of the inner container 2200 through the space between the inner container 2200 and the coupling 2230. The temperature sensing line 2320 may extend through the space between the inner container 2200 and the outer tube 2250.

[0255] Another portion of the temperature sensing line 2320 may pass through the outer container 2250 via a through hole in the outer container 2250 and extend to the outside of the outer container 2250 .

[0256] The heater 2300 may further include a protrusion 301 protruding outward. A portion of the temperature sensing line 2320 may be connected to the protrusion 301 of the heater 2300.

[0257] The suction sensor 2330 may detect a pressure change in the airflow channel in response to a user's suction action. The suction sensor 2330 may be disposed adjacent to the first support portion 2210 .

[0258] The positions and shapes of the above-described components are not limited to the disclosed embodiments and may be modified in various ways.

[0259] Figure 5is a cross-sectional view of one embodiment of the aerosol generating module disclosed above taken along another direction.

[0260] The same reference numerals as those in the above-described embodiment denote the same components, and descriptions of the same components overlapping with the above contents will be omitted.

[0261] In the embodiment shown in the figure, the through hole 2254 of the outer container 2250 and the wiring channel 2270 of the sealing portion 2270 can be arranged at a certain distance from the central axis along the longitudinal direction of the aerosol generating article 220.

[0262] At least a portion of the sealing portion 2270 may be inserted into the through hole 2254 of the outer container 2250. One or more wires or magnetic field generators 2310 may extend through the through hole 2254 of the outer container 2250 and the wiring channel 2272 of the sealing portion 2270.

[0263] Figure 6 is an enlarged cross-sectional view of some of the components of the embodiments of the aerosol generating module disclosed above.

[0264] The figure discloses the air movement process according to the puffing action of the user in an embodiment of the aerosol generating module.

[0265] When the user contacts the aerosol generating article 220 with the mouth to perform an inhalation action, a pressure difference may be generated between the outside of the aerosol generating module and the internal space of the housing 2100 , causing external air to flow into the housing 2100 through the first support portion 2210 .

[0266] External air introduced into the housing 2100 may pass through the inflow channel 2204 of the first support portion 2210. The air having passed through the inflow channel 2204 may pass through the first air hole 2231 and the second air hole 2241 and reach the inner channel 2202 between the inner container 2200 and the heater 2300. The air moving along the inner channel 2202 may flow into the second support portion 2220.

[0267] The air introduced into the delivery channel 2227 of the second support portion 2220 may pass through the delivery channel 2227 in a U-shape according to the shape of the second support portion 2220 , and flow into the end of the aerosol generating article 220 inserted into the accommodating space 2205 .

[0268] The air introduced into the aerosol generating article 220 may mix with vaporized particles generated when the aerosol generating article 220 is heated to generate an aerosol. The user may inhale the aerosol generated in the accommodation space 2205 by a puffing action of inhaling the aerosol generating article 220.

[0269] Figure 722 is a view showing an example of an air movement process in the second supporting portion 2220 according to the above embodiment.

[0270] Once an aerosol-generating article (not shown) is inserted into the aerosol generator 200 and contacts the inner surface of the second support portion 2220 , a delivery channel 2227 may be formed in the space between the second support portion 2220 and the aerosol-generating article (not shown).

[0271] The air moving along the inner passage 2002 between the inner container 2200 and the heater 2300 may flow into the delivery passage 2227 of the second support portion 2220. The delivery passage 2227 may have a U-shape following the shape of the second support portion 2220. The air moving along the delivery passage 2227 may reach the end of the aerosol generating article.

[0272] However, the arrangement and shape of the delivery passage 2227 are not limited to the above-described embodiment, and may be changed in various ways.

[0273] In the disclosed example, the aerosol generator 200 uses a film-type heater external to the aerosol-generating article to heat the aerosol-generating article.

[0274] As described, when the aerosol-generating article is inserted into the tubular interior space, the aerosol generator 200 may include a heater capable of heating the aerosol-generating article using one of several methods.

[0301] The heater support rib 2526 may be formed at the upper end of the peripheral portion 2521 of the lower pipe 2502. The heater support rib 2526 may be formed by recessing the upper end of the inner circumferential surface of the peripheral portion 2521 of the lower pipe 2502 radially outward.

[0307] An embodiment of an aerosol generator including a film-type heat generating pattern portion heater as a heater for heating a cigarette rod including an aerosol generating article and a sensor pattern portion for temperature control is described below.

[0308] The controller 100 may control the power supplied from the power supply unit 110 to the heater assembly 2630 based on the temperature measured using the sensor pattern portion disclosed below.

[0309] Here, the heater assembly 2630 performs the same heating function as the above-described heating assembly 2530. However, since the heater assembly 2630 includes a heat generating pattern portion or a sensor pattern portion, the heater assembly is separately referred to as the heater assembly 2630 to distinguish the heater type.

[0310] The controller 100 may check the state of each component included in the aerosol generator 200 and determine whether the aerosol generator 200 is in an operable state.

[0311] The aerosol generator 200 may include a substrate on which a circuit for transmitting an electrical signal transmitted from the controller 100 is printed. The substrate may be disposed inside a body of the aerosol generator 200.

[0312] Therefore, the heater assembly 2630 may be electrically connected through the controller 100, the power supply unit 110, and the substrate, or the controller 100 may include the substrate performing the same function.

[0313] The substrate may connect the aerosol generator 200 and the controller 100 through a bridge portion. According to an implementation method, the bridge portion may be included in the aerosol generator 200, the controller 100, or a substrate connected to the controller 100.

[0314] The bridge portion may be disposed inside the body of the aerosol generator 200. Thus, the bridge portion may electrically connect the heater assembly 2630 with the substrate.

[0315] The bridge portion may be disposed between the heater assembly 2630 and the substrate 121. The bridge portion may include a conductive pattern portion. The bridge portion may be formed of a material having low thermal conductivity. The bridge portion may be formed of a material having lower thermal conductivity than the heater assembly 2630. The bridge portion may be formed of a material having a temperature coefficient of resistance (TCR) less than the TCR of the heater assembly 2630.

[0316] Therefore, power can be transmitted to the heater assembly 2630 through the bridge portion, but heat generated from the heater assembly 2630 and transmitted to the substrate through the bridge portion can be reduced, and overheating, which may cause malfunction or damage to the substrate, can be prevented. Moreover, the surrounding area other than the heater assembly 2630 can be prevented from being heated.

[0317] Fig.13 An aerosol generator according to another embodiment is shown.

[0318] Reference Fig.13 , the pipe 2601 constituting the body of the aerosol generator 200 may be hollow and have an insertion space 2604 in the pipe. The insertion space 2604 may be open at one side and the other side of the pipe 2601.

[0319] One side of the insertion space 2604 may be open to the outside. The cigarette rod 210 may be inserted into the duct 2601 through the opening of the insertion space 2604. The insertion space 2604 may have a cylindrical shape that is elongated in the vertical direction.

[0320] In the disclosed example, the duct 2601 constituting the body of the aerosol generator 200 includes an upper duct and a lower duct.

[0321] In order to distinguish the heater including the heat generating pattern portion or the sensor pattern portion, the duct 2601 constituting the body of the aerosol generator 200 is described as including the first duct 2602 and the second duct 2603 .

[0322] The first pipe 2602 and the second pipe 2603 can be coupled or connected to each other to form the pipe 2601.

[0323] The first pipe 2602 may be disposed on top of the second pipe 2603. The inner circumferential surface of the first pipe 2602 may surround the upper portion of the insertion space 2604, and the inner circumferential surface of the second pipe 2603 may surround the lower portion of the insertion space 2604. The lower end of the second pipe portion 2603 may be open, and thus an inlet 2605 is provided.

[0324] The inlet 2605 may communicate with the insertion space 2604. Air may flow into the insertion space 2604 through the inlet 2605.

[0325] The heater assembly 2630 can be disposed and fixed inside the pipe 2601.

[0326] The upper end peripheral portion of the heater assembly 2630 may be covered by the upper end peripheral portion of the pipe 2601 .

[0327] The outer circumferential surface of the heater assembly 2630 may be covered by the inner circumferential surface of the pipe 2601. The heater assembly 2630 may surround at least a portion of the insertion space 2604. The inner circumferential surface of the heater assembly 2630 may define the insertion space 2604. The heater assembly 2630 may heat the insertion space 2604.

[0328] Fig.14 is a cross-sectional view of the second layer 2722 in one embodiment of an aerosol generator.

[0329] The inner tube 2710 may be formed of a thermally conductive material.

[0330] The inner pipe 2710 can be formed of a conductor or a non-conductor. The inner pipe can be formed of various suitable materials with good thermal conductivity.

[0331] The inner pipe 2710 may have an appropriate strength to maintain the shape of the insertion space 2604 for accommodating the cigarette rod 210 , and may have an appropriate thickness to effectively transfer heat from the heat emitting pattern part 2730 .

[0332] The first layer 2721 may cover the insides of the heat emitting pattern part 2730 and the sensor pattern part 2740 .

[0333] The first layer 2721 may have electrical insulation properties. The first layer 2721 may have heat resistance sufficient to withstand heat generated by the heat generating pattern part 2730 .

[0334] The first layer 2721 may be made of paper, glass, ceramic, or coated metal.

[0335] The first layer 2721 may be made of various suitable materials and is not limited to the above examples.

[0336] The second layer 2722 may cover the outside of the heat emitting pattern part 2730 and the sensor pattern part 2740. The second layer 2722 may have electrical insulation properties. The second layer 2722 may have heat resistance sufficient to withstand the heat generated by the heat emitting pattern part 2730.

[0337] The second layer 2722 may have heat insulating properties. The second layer 2722 may reduce heat loss from the heater assembly 2630 to the outside.

[0338] The heater assembly 2630 may include a heating pattern portion 2730. The heating pattern portion 2730 may be integrally printed on the first layer 2721. The heating pattern portion 2730 may be formed between the first layer 2721 and the second layer 2722. The heating pattern portion 2730 may be implemented using an element having a resistor. When power is supplied from the power supply unit 110 and current flows through the resistive heating element, the resistive heating element may generate heat. The heating pattern portion 2730 may be made of aluminum, tungsten, gold, platinum, silver, copper, nickel, palladium, or a combination thereof.

[0339] The heat emitting pattern part 2730 may include an alloy and is not limited to the above examples. The resistance of the heat emitting pattern part 2730 may be set in various ways according to the constituent material, length, width, thickness or pattern of the resistance element.

[0340] The heat emitting pattern part 2730 may be made of a material with a low TCR.

[0341] When the TCR is small, the power loss during heating may be low and the heat transfer efficiency may be high. For example, the heat generating pattern portion 2730 may be constantan. Constantan may be an alloy in which nickel and copper are combined in a ratio of 45% and 55%. The TCR of constantan is 0.000008 and may be close to 0.

[0342] Therefore, the heat transfer efficiency in which the heat emitting pattern part 2730 generates heat and transfers the heat to the insertion space 2604 may be high.

[0343] The heater assembly 2630 may include a sensor pattern portion 2740. The sensor pattern portion 2740 may be integrally printed on the first layer 2721 together with the heat generating pattern portion 2730. The sensor pattern portion 2740 may be disposed between the first layer 2721 and the second layer 2722. The sensor pattern portion 2740 may be formed by printing a resistor having a TCR. The sensor pattern portion 2740 may be formed adjacent to the heat generating pattern portion 2730.

[0344] The sensor pattern part 2740 may be formed of at least one of ceramic, semiconductor, metal, and carbon. Like the heat emitting pattern part 2730, the sensor pattern part 2740 may be made of a resistive element or a conductive element.

[0345] The resistance of the resistor of the sensor pattern portion 2740 may vary according to temperature. The change in resistance may be obtained by measuring the change in voltage when current flows through the resistor of the sensor pattern portion 2740. Therefore, by measuring the change in resistance of the sensor pattern portion 2740 according to the change in temperature, the temperature of the heater assembly 2630 may be measured. However, the embodiment is not limited thereto. The change in resistance may be obtained by applying a voltage to the resistor of the sensor pattern portion 2740 and measuring the change in current.

[0346] The first terminal 2731 may be formed at an end of the heat generating pattern portion 2730. The first terminal 2731 may electrically connect the heat generating pattern portion 2730 and the power supply unit 110. The first terminal 2731 may correspond to an electrical connection terminal for supplying power provided by the power supply unit 110 to the heat generating pattern portion 2730. The first terminal 2731 may be exposed to the outside from the heater assembly 2630.

[0347] The second terminal 2741 may be formed at an end of the sensor pattern portion 2740. The second terminal 2741 may electrically connect the sensor pattern portion 2740 and the power supply unit 110. The second terminal 2741 may correspond to an electrical connection terminal for supplying power provided by the power supply unit 110 to the sensor pattern portion 2740. The second terminal 2741 may be exposed to the outside from the heater assembly 2630.

[0348] The terminal portion 2735 may extend from the layer 2720 toward one side. The terminal portion 2735 may be exposed from the layer 2720. The heat generating pattern portion 2730 may extend from the layer 2720 to the terminal portion 2735 and be printed on the terminal portion 2735. The first terminal 2731 may be formed at an end of the heat generating pattern portion 133 and disposed on the terminal portion 2735. The sensor pattern portion 2740 may extend from the layer 2720 to the terminal portion 2735 and be printed on the terminal portion 2735. The second terminal 2741 may be formed at an end of the sensor pattern portion 2740 and disposed on the terminal portion 2735.

[0349] Figures 15 to 17 The coupling circuits and modules of the aerosol generator are shown.

[0350] Reference Figures 15 to 17 , the aerosol generator 200 may include a first substrate 2621. The first substrate 2621 may transmit electrical signals to control the operation of various components. A circuit pattern for transmitting electrical signals may be formed on the first substrate 2621. The first substrate 2621 may be electrically connected to the power supply unit 300 and the controller 100. The controller 100 may be mounted on the first substrate 2621. The first substrate 2621 may be referred to as a main board.

[0351] The aerosol generator 200 may include a bridge portion 2650. The bridge portion 2650 may electrically connect the heater assembly 2630 and the first substrate 2621. One end of the bridge portion 2650 may be coupled to the terminal portion 2735 of the heater assembly 2630. The opposite end of the bridge portion 2650 may be coupled to the first substrate 2621.

[0352] The bridge portion 2650 may include a second substrate 2651. The second substrate 2651 may be referred to as a connecting substrate. The second substrate 2651 may extend from the heater assembly 2630 to the first substrate 2621. The second substrate 2651 may be formed of a flexible printed circuit board (FPCB). The second substrate 2651 is flexible and can be easily installed inside the aerosol generator 200.

[0353] The bridge portion 2650 may include a connection pattern portion 2650 printed on the second substrate 2651. The connection pattern portion 2650 may extend from one end of the second substrate 2651 to the opposite end of the second substrate 2651. The connection pattern portion 2650 may be made of a conductive element.

[0354] A plurality of connection pattern parts 2650 may be formed to correspond to the first terminal 2731 and the second terminal 2741. The connection pattern part 2650 may be covered with a layer having electrical and thermal insulation properties.

[0355] The bridge portion 2650 may include a connection terminal 2653. The connection terminal 2653 may be provided at one end of the bridge portion 2650. The connection terminal 2653 may be formed at one end of each connection pattern portion 2650. A plurality of connection terminals 2653 may be provided to correspond to the first terminal 2731 and the second terminal 2741. The connection terminal 2653 may be electrically connected to the first terminal 2731 and the second terminal 2741 of the terminal portion 2735. The connection terminal 2653 may be coupled or bonded to the first terminal 2731 and the second terminal 2741. For example, the connection terminal 2653 may be bonded to the first terminal 2731 and the second terminal 2741 by welding.

[0356] The bridge portion 2650 may include a connector 2654. The connector 2654 may be formed at opposite ends of the connection pattern portion 2650. The connector 2654 may face away from the connection terminal 2653 relative to the connection pattern portion 2650. The connector 2654 may be coupled to the first substrate 2621 to couple the connection pattern portion 2650 of the bridge portion 2650 and the first substrate 2621.

[0357] Thus, the first substrate 2621 and the heater assembly 2630 may be electrically connected to each other. The power supply unit 110 connected to the first substrate 2621 may supply power to the heater assembly 2630 through the bridge portion 2650 .

[0358] The heater assembly 2630 may be made of a material having a smaller temperature coefficient of resistance (TCR) than the bridge portion 2650. The heat generating pattern portion 2730 may be made of a material having a smaller temperature coefficient of resistance (TCR) than the bridge portion 2650.

[0359] For example, the heat generating pattern portion 2730 may be constantan, whose TCR is 0.000008 and approaches 0, and the bridge portion 2650 may be nickel having a TCR of 0.006 or copper having a TCR of 0.00386.

[0360] The materials of the connection pattern portion 2263 of the heat generating pattern portion 2730 and the bridge portion 2650 are not limited to the above materials. As the TCR decreases, the heat transfer efficiency may be improved and the loss of available power may be reduced. In addition, as the TCR decreases, the temperature rise rate of the powered heating element may increase.

[0361] The connection pattern portion 2650 may have low thermal conductivity. The bridge portion 2650 may be made of a material having lower thermal conductivity than the heater assembly 2630. The connection pattern portion 2650 may be made of a material having lower thermal conductivity than the heat generating pattern portion 2730 of the heater assembly 2630. The heat generating rate of the connection pattern portion 2650 may be lower than the heat generating rate of the heat generating pattern portion 2730.

[0362] The connection pattern part 2650 may be covered by a heat insulating layer.

[0363] Therefore, heat generated from the heater assembly 2630 and conducted to the first substrate 2621 through the bridge portion 2650 can be reduced, and the first substrate 2621 can be prevented from being overheated and damaged. In addition, other components except the heater assembly 2630 can be prevented from being heated.

[0364] Another embodiment of the aerosol generator is disclosed below.

[0367] Reference Fig.18 , the heater 2950 may be inserted into the hollow portion 2814 of the heating needle 2810. The heater 2950 may be elongated in the vertical direction. The heater 2950 may be a magnetic component and may generate heat by induction current. The heater 2950 may have the shape of a rolled thin plate.

[0368] The sensor 2850 may be inserted into the hollow portion 2814. The sensor 2850 may be disposed below the heater 2950. The sensor 2850 may sense the temperature of the heater 2950. A sensor lead 2859 may be connected to the sensor 2850. A pair of sensor leads 2851 may be provided. The sensor lead 2851 may transmit power supplied from a power source to the sensor 2850. The sensor lead 2851 may transmit a control signal to the sensor 2850.

[0369] The reinforcing member 2840 may be inserted into the hollow portion 2814 of the heating needle 2810. The reinforcing member 2840 may be disposed below the sensor 2850. The reinforcing member 2840 may support the lower portion of the sensor 2850. The reinforcing member 2840 may be fixed in the hollow portion 2814 to be in close contact with the inner circumferential surface of the heating needle 2810. The reinforcing member 2840 may fill the hollow portion 2814. The sensor lead 2859 may be exposed to the outside of the heating needle 2810 through the reinforcing member 2840.

[0370] Fig.19 is a view showing a portion of a heater in an embodiment of an aerosol generator.

[0371] Reference Fig.19The heater 2950 may be elongated in the vertical direction. The heater 2950 may have a cylindrical shape. The heater 2950 may be flexible. The heater 2950 may be formed into a cylindrical curled or bent shape made of a thin plate. The bending direction BD in which the heater 2950 is bent may intersect with the longitudinal direction LD of the heater 2950. For example, the bending direction BD of the heater 2950 may be orthogonal to the longitudinal direction LD of the heater 2950.

[0372] Reference Fig.19 (a), the heater 2950 may be bent in the bending direction BD. One side of the heater 2950 may be cut off along the longitudinal direction LD of the heater 2950. The heater 2950 may be provided with a slit 2953 extending a long distance along the longitudinal direction LD on one side of the cylindrical shape. The heater 2950 may have a C-shaped cross section. The heater hole 2954 may be defined as a space formed inside the heater 2950. The heater 2950 may surround the side portion of the heater hole 2954. The heater hole 2954 may extend vertically inside the heater 2950. The heater hole 2954 may be connected to the slit 2953. The heater hole 2954 may be open at the top and the bottom.

[0373] Reference Fig.19 (b), as another example, the heater 2950 may have a cylindrical shape curled in the circumferential direction. The heater 2950 may have a spiral cross section. Even in this case, the heater hole 2954 may be formed inside the heater 2950. Even in this case, a slit 2953 extending a long distance in the longitudinal direction LD may be formed on one side.

[0374] The curvature of the heater 2950 at the second position 2952 may be smaller than the curvature of the heater 2950 at the first position 2951. The radius of curvature of the heater 2950 at the second position 2952 may be greater than the radius of curvature of the heater at the first position 2951. The heater hole 2954 and the slit 2953 of the heater 2950 at the second position 2952 may be larger than the heater hole and the slit of the heater at the first position 2951.

[0375] Heater 2950 may be formed of an elastic material. When heater 2950 is curled and in first position 2951, the heater may be subject to an elastic force tending to expand the heater outward to return to second position 2952. Heater 2950 may have a restoring force or elastic force in a direction in which the curvature decreases. Heater 2950 may have a restoring force or elastic force that increases the radius of curvature or radius of the heater. Heater 2950 may have a restoring force or elastic force that increases the size of heater hole 2954 and slit 2953.

[0376] Fig. 20 is a view showing a heater in an embodiment of an aerosol generator.

[0377] Reference Fig. 20 , the heater 2950 at the first position 2951 may be inserted into the hollow portion 2814 of the heating needle 2810. The diameter D1 of the outer circumferential surface of the heater 2950 at the first position 2951 may be smaller than the diameter D3 of the hollow portion 2814. The diameter D2 of the outer circumferential surface of the heater 2950 at the second position 2952 may be larger than the diameter D3 of the hollow portion 2814.

[0378] In the hollow portion 2814, the heater 2950 may have an elastic force or a restoring force applied from the first position 2951 to the second position 2952. In the hollow portion 2814, the diameter D1 of the outer circumferential surface of the heater 2950 may be equal to the diameter D2 of the hollow portion 2814. In the hollow portion 2814, the curvature of the outer circumferential surface of the heater 2950 may be equal to the curvature of the hollow portion 2814. In the hollow portion 2814, the heater 2950 may push the inner circumferential surface of the heating needle 2810 by elastic force and apply pressure to the inner circumferential surface of the heating needle 2810.

[0379] Therefore, the outer circumferential surface of the heater 2950 can be fixed in the hollow part 2814 to be in close contact with the inner circumferential surface of the heating needle 2810. In addition, a bonding operation of fixing the heater 2950 to the inside of the heating needle 2810 may be unnecessary, and a lead wire of the heater 2950 may not be required. Therefore, the manufacturing process can be simplified. Moreover, problems such as twisting or breaking of the lead wire can be avoided.

[0380] The heater 2950 disclosed in the figure may be inserted into the heating needle 2810. When the heater 2950 is inserted into the heating needle 2810, the heater 2950 may be bent to the first position 2951. In this case, the heater 2950 in the first position 2951 may be inserted into the hollow portion 2814 of the heating needle 2810 through the opening. The heater 2950 may be inserted into the hollow portion 2814 with the heater bent to the first position 2951. When the heater 2950 is inserted into the heating needle 2810, the heater 2950 may be in close contact with the inner circumferential surface of the heating needle 2810 and fixed in the heating needle 2810 by the pressure in the hollow portion 2814. When the heater 2850 is inserted into the heating needle 2810, the heater 2950 may be disposed at a higher position than the cover 2851.

[0382] Reference Fig.21 , the channel of the pipe 208 can be formed in a cylindrical shape. The channel of the pipe 208 can surround the side around the needle body 2811 and the needle tip 2812.

[0383] The induction coil 2860 may be wound a plurality of times around the outer circumferential surface of the pipe 2821 to surround the outer circumferential surface. The induction coil 2860 may surround the heater 2950. The heater 2950 may generate heat by induction heating through the induction coil 2860.

[0384] The hollow portion 2814 may be communicated with the cover hole 254. The heater 2950 may extend vertically. The heater 30 may be inserted into the hollow portion 2814 through the cover hole 254 and fixed in the hollow portion 2814. The heater 2950 may be in close contact with the inner circumferential surface of the needle-shaped portion body 2811 in the hollow portion 2814. The heater 2950 may be arranged above the bottom of the insertion space 2824. The heater 2950 may be arranged above the first cover portion 2831. The heater 2950 may be arranged above the first flange 2901. The first line L1-L1' may be defined as an imaginary line in the same plane as the bottom of the insertion space 2824 or the top surface of the first cover portion 2831. The second line L2-L2' is in the same plane as the bottom of the heater 2950 and may be defined as an imaginary line parallel to the first line L1-L1'. The second line L2 - L2 ′ may be spaced apart upward from the first line L1 - L1 ′ by a predetermined distance d. The predetermined distance d may be greater than or equal to 0 mm.

[0385] Therefore, the influence of the heat generated by the heater 2950 on the first covering portion 2831 can be reduced. In addition, the following situations can be prevented: the first covering portion 2831 is thermally deformed to form a gap between the first covering portion 2831 and the heating needle portion 2810, or the first covering portion 2831 is thermally deformed to expand the gap between the first covering portion 2831 and the heating needle portion 2810, and foreign matter such as liquid can be prevented from leaking through the gap.

[0386] Fig. 22 is a view showing a heater including an induction coil as an embodiment of an aerosol generator.

[0387] Reference Fig. 22 , the sensor 2850 may be inserted into the heater hole 2954. The sensor 2850 may have a shape corresponding to the heater hole 2954. The sensor 2850 may be elongated in the vertical direction. For example, the sensor 2850 may have an elongated cylindrical shape. The heater 2950 may surround the sensor 2850. The sensor 2850 may sense the temperature of the heater 2950 inside the heater 2950.

[0388] The sensor lead 2851 may extend from the sensor 2850 to below the heater 2950. The sensor lead 2851 may extend through the reinforcing member 2840 to below the second covering portion 2932.

[0389] The reinforcing member 2840 may overlap with the top surface of the first flange 2901. The reinforcing member 2840 may extend vertically. The upper end of the reinforcing member 2840 may be disposed at a position higher than the top surface of the first flange 2901. The lower end of the reinforcing member 2840 may be disposed at a position lower than the top surface of the first flange 2901. The reinforcing member 2840 may strengthen the rigidity of the needle body 2811 around the top surface of the first flange 2901 and inside the top surface of the first flange 2901.

[0390] Therefore, the influence of the heat generated by the heater 2950 on the first covering portion 2831 can be reduced. In addition, the following situations can be prevented: the first covering portion 2831 is thermally deformed to form a gap between the first covering portion 2831 and the heating needle portion 2810, or the first covering portion 2831 is thermally deformed to expand the gap between the first covering portion 2831 and the heating needle portion 2810, and foreign matter such as liquid can be prevented from leaking through the gap.

[0391] In addition, the reinforcing member 2840 may prevent the heating needle 2810 from breaking around the first flange 2901 .

[0452] The first cover 4241 and the second cover 4242 may be formed of a porous material that allows air to pass through but prevents the medium 4240 from being discharged. The product body 4210 may be formed of paper or the like surrounding the first cover 4241, the medium 4240, the second cover 4242, the cooling portion 4230, and the filter 4220.

[0453] like Fig.28 and Fig.29 As shown, the mounting portion 4110 may include a mounting body 4111 having an accommodation space 4112 for the medium 4240. The mounting body 4111 may be formed in a cylindrical shape defining the accommodation space 4112 therein, and the mounting body 4111 may be formed of a dielectric material.

[0454] The dielectric material may be a thermoplastic resin, such as a polyester-based resin, a cellulose-based resin, a polycarbonate-based resin, an acrylic-based resin, a styrene-based resin, a polyolefin-based resin, a vinyl chloride-based resin, an amide-based resin, an imide-based resin, a polyethersulfone-based resin, a sulfone-based resin, a polyetheretherketone-based resin, a polyphenylene sulfide-based resin, a vinyl alcohol-based resin, a vinylidene chloride-based resin, a vinyl butyral-based resin, an allyl ester-based resin, a polyoxymethylene-based resin, or an epoxy-based resin. The mounting portion 4110 may be formed of any one of the above materials or a combination of two or more of the above materials.

[0455] The top surface 4113 of the mounting body may be provided with an inlet 4116 for the product body 4210 to enter and exit, and the antenna 4130 may be fixed to the circumferential surface 4114 of the mounting body. In addition, a heating portion wire 4126 for controlling the heating portion 4120 may be fixed to the bottom surface 4115 of the mounting body.

[0456] The heating portion 4120 may be provided with an internal heating type heat source that supplies heat energy from inside the product body 4210 , or the heating portion 4120 may be provided with an external heating type heat source that supplies heat energy from outside the product body 4210 .

[0457] Fig.29 An example of an internal heating type heating portion is shown. According to the present embodiment, the heating portion 4120 may include a coil 4121 that inductively heats a conductor (eg, a metal plate) 4250 disposed inside a medium 4240 .

[0458] In this case, the coil 4121 may be arranged inside the mounting body 4111 to surround the accommodation space 4112. In other words, the coil 4121 may be wound along the height direction (Y-axis direction) of the mounting body to surround the accommodation space 4112.

[0459] The coil 4121 may be supplied with power via the heating portion line 4126 . Fig.29 The illustrated embodiment shows an example in which the heating portion line 4126 is connected to the coil 4121 through the bottom surface 4115 of the mounting body.

[0460] When current is supplied to the coil 4121 through the heating portion wire 4126, the conductor 4250 provided inside the medium 4240 is heated. Therefore, when the user inhales external air through the filter 4220, the aerosol generated in the medium 4240 will be supplied to the user through the filter 4220.

[0461] Fig.30 are views showing other examples of the above-mentioned connection module.

[0462] Fig.30 (a) shows another embodiment of the internal heating type heater. According to this embodiment, the heating portion 4120 may include a heater 4123, and when the product body 4210 is inserted into the accommodation space 4112, the heater 4123 contacts the medium 4240 through the product body 4210.

[0463] According to the present embodiment, the heater 4123 may be in the form of a metal rod or a metal plate fixed to the bottom surface 4115 of the mounting body and located in the accommodation space 4112. In this case, when the product body 4210 is inserted into the accommodation space 4112, the free end of the heater 4123 will be placed in the medium 4240 through the first cover 4241 (bottom surface of the product body).

[0464] Fig.30 (b) and Fig.30 (c) shows an embodiment of the heating part of the indirect heating type. Fig.30 (b) and Fig.30 (c) is similar in that they include a tubular heater 4124 surrounding the circumferential surface of the product body 4210 inserted into the accommodation space 4112. The tubular heater 4124 may be fixed to the mounting body 4111 to be located within the accommodation space 4112.

[0465] Although Fig.30 (b) The heater 4124 is supplied with power through the heater line 4126, but Fig.30 The heater 4124 of (c) may be heated by a coil 125 located inside the mounting body 4111 .

[0466] As disclosed in the above-mentioned embodiment, the antenna 4130 may include: a sheet member (first sheet member) 4131 fixed to the mounting body 4111 and disposed outside the accommodating space 4112; and a grounding portion (first grounding portion) 4132 fixed to the mounting body 4111 and disposed outside the accommodating space 4112. The sheet member 4131 and the grounding portion 4132 may be formed of a conductor, such as a metal plate, and the sheet member 4131 and the grounding portion 4132 may be fixed to the mounting body 4111 to be disposed at positions separated from each other.

[0467] The antenna 4130 may be supplied with power through a feeder (first feeder) 4134 connected to the sheet 4131 and an antenna wire 4133 connecting the feeder 4134 to the communicator 400. Feeding means an operation of applying current to the sheet 4131.

[0468] In order to set the radiation direction of the antenna 4130, the sheet member 4131 and the ground portion 4132 may be arranged in various ways. Specifically, when the mounting body 4111 is formed in a cylindrical shape, the sheet member 4131 and the ground portion 4132 may be arranged to be spaced apart from each other in the circumferential direction of the mounting body 4111, or the sheet member 4131 and the ground portion 4132 may be arranged to be spaced apart from each other in the height direction (Y-axis direction) of the mounting body 4111.

[0469] Contrary to what is shown in the figure, the mounting body 4111 may be formed in a prism shape. In this case, the sheet member 4131 and the grounding portion 4132 may be arranged spaced apart from each other along the circumferential direction of the mounting body 4111 (see Fig.28 ), or the sheet member 4131 and the grounding portion 4132 may be arranged spaced apart from each other along the height direction of the mounting body 4111 (see Fig.31 ).

[0470] The shape of the sheet member 4131, the size and thickness of the sheet member 4131, the distance between the sheet member 4131 and the ground portion 4132, the material and thickness of the mounting body 4111 as a dielectric, etc. should be set according to the desired transmission and reception frequency band.

[0471] In the case where the mounting body 4111 is formed in a cylindrical shape and in the case where the mounting body 4111 is formed in a prismatic shape, the sheet member 4131 and the grounding portion 4132 fixed on the outer circumferential surface of the mounting body 4111 will have a curved shape.

[0472] As shown above Fig.29As shown in (b), the sheet member 4131 and the grounding portion 4132 have a curved shape according to the cross-sectional shape of the mounting body 4111, and this shape of the sheet member and the grounding portion can improve the transmission and reception efficiency in some cases (depending on the frequency band set for transmission and reception).

[0473] The communication and aerosol generator 100 having the above structure may be provided in a communication terminal having a communicator and a power supply unit, thereby realizing a wireless communication function and an aerosol generating function.

[0474] In order to ensure the compatibility of the connecting module 4100 with the communication terminal, the heating part line 4126 can be provided with a heating part connector 4127 which is removably connected to the circuit (substrate, etc.) of the communication terminal, and the antenna wire 4133 can be provided with an antenna connector (first antenna connector) 4135 which is removably connected to the circuit (substrate, etc.) of the communication terminal.

[0475] The coupling module 4100 may further include a control board 4160 configured to control the operation of the heating portion 4120 , and a communicator 400 configured to control wireless communication through the antenna 4130 .

[0476] The control board 4160 can be configured as a device for controlling the power supplied to the coils 4121, 4125 or the heaters 4123, 4124 through the heating part line 4126, and the communicator (communication module or communication circuit) 300 can be configured as a device for implementing a wireless communication function that is suitable for the purpose of the communication terminal to be installed in the connection module 4100.

[0477] In order to ensure the compatibility of the communication with the aerosol generator 100 having the control board 4160 and the communicator 400, the connection module 4100 may further include a PCB 4140 on which the controller and the communicator are fixed.

[0478] PCB 4140 can be provided with a first connector 4141, a second connector 4142 and a third connector 4143, the heating part connector 4127 is connected to the first connector 4141, the antenna connector 4135 is connected to the second connector 4142, and the controller of the communication terminal (terminal controller or application processor) is connected to the third connector 4143.

[0479] Therefore, the embodiments of the present disclosure can provide a connection module with communication and an aerosol generator, which can realize both wireless communication function and aerosol generation function, and the connection module is suitable for various communication terminals.

[0481] The coupling module 4100 according to the present embodiment is different from the previous embodiment in that the coupling module 4100 according to the present embodiment further includes an extending body 4117 extending from the mounting body 4111 .

[0482] The extension body 4117 may be a plate protruding from the circumferential surface of the mounting body 4111 along the diameter direction (X-axis direction) of the mounting body. The extension body 4117 may be formed of a dielectric material, which may be the same as or different from the material of the mounting body 4111.

[0483] When the extension body 4117 is provided, the feeder 4134 provided to the sheet member 4131 may be provided to the extension body 4117. The antenna wire 4133 may be connected to the feeder 4134 by bonding. In this case, the extension body 4117 may improve the durability of the coupling module 4100 by maintaining a stable connection between the antenna wire 4133 and the feeder 4134.

[0484] Fig.32 (a) shows the sheet member 4131 and the grounding portion 4132 are spaced apart from each other along the circumferential surface of the mounting body 4111, while Fig.32 (b) shows a situation where the sheet member 4131 and the grounding portion 4132 are spaced apart from each other along the height direction (Y-axis direction) of the mounting body 4111 .

[0485] like Fig.32 As shown in (c), the sheet member 4131 can be fixed to the circumferential surface of the mounting body 4111, the feed line 4134 can be fixed to the top surface of the extension body 4117, and the grounding portion 4132 can be fixed to the bottom surface of the extension body 4117 (opposite to the surface to which the feed line is fixed).

[0486] If you need to set the radiation direction of antenna 4130, Fig.32 The connection module 4100 of (c) may be configured such that the grounding portion 4132 is fixed on the same surface as the surface on which the feeder line 4134 is provided (see the dotted line). Fig.32 Compared to the arrangement shown in (c), the sheet member 4131 can be fixed to the extension body 4117, and the grounding portion 4132 can be fixed to the mounting body 4111.

[0487] Fig.33 41 is a view showing another embodiment of the coupling module 4100 . In the coupling module 4100 according to this embodiment, a sheet member 4131 and a grounding portion 4132 may be provided on the extension body 4117 .

[0488] like Fig.33As shown in (a), the sheet 4131 and the grounding portion 4132 may be fixed to the extension body 4117 so that the sheet 4131 and the grounding portion 4132 are spaced apart from each other along the height direction (Y-axis direction) of the mounting body. The sheet 4131 and the grounding portion 4132 may be disposed on the same plane provided by the extension body 4117. This figure shows an example case where the sheet and the grounding portion are fixed to the top surface of the extension body 4117.

[0489] and Fig.33 Contrary to the case shown in (a), the sheet member 4131 and the grounding portion 4132 may be fixed to the extension body 4117 so as to be spaced apart from each other along a diameter direction (eg, Z-axis or X-axis direction) of the mounting body.

[0490] Fig.33 (b) shows an embodiment in which one of the sheet member 4131 and the ground portion 4132 is fixed to the top surface of the extension body 4117 , and the other of the sheet member and the ground portion is fixed to the bottom surface of the extension body 4117 .

[0491] For the communication and aerosol generator 100 having the above-described structure, when the article 200 is inserted into the accommodation space 4112 , the dielectric constant of the mounting portion 4110 may change, resulting in degradation of the functional setting for the antenna 4130 .

[0492] In order to solve the above problem, the connection module 4100 may further include a second antenna 4170 .

[0493] Fig.34 is a view showing another embodiment of a coupling module in which an antenna of a communicator is coupled to an aerosol generator.

[0494] like Fig.34 As shown in FIG. 4 , the connection 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 in the previous embodiment, so they are not repeated here.

[0495] The second antenna 4170 may include a dielectric body 4171 formed by a dielectric material and disposed at a point separated from the mounting portion 4110, a second sheet member 4172 formed by a conductor and fixed to the dielectric body 4171, and a second grounding portion 4173 formed by a conductor and fixed to the dielectric body 4171, and the second grounding portion 4173 is disposed at a point separated from the second sheet member 4172.

[0496] The dielectric body 4171 may be made of the same material as the mounting body 4111, or the dielectric body 4171 may be made of a different material from the mounting body 4111. The second sheet 4172 and the second grounding portion 4173 may be disposed on the same plane provided by the dielectric body 4171, or the second sheet 4172 and the second grounding portion 4173 may be fixed to the dielectric body 4171 so that the second sheet 4172 and the second grounding portion 4173 face each other. In the present embodiment, the latter case is taken as an example for description.

[0497] The coupling module 4100 according to the present embodiment may include a PCB 4140 provided with a circuit for switching the first antenna 4130 and the second antenna 4170, a control board 4160 provided on the PCB to control the operation of the heating part 4120, and Figure 1 The communicator 400 is configured to supply current to the antennas 4130 and 4170.

[0498] The second sheet 4172 may be provided with a second feeder 4174. The second feeder 4174 may be connected to the communicator 400 via a second antenna conductor 4175. To this end, the PCB may be provided with a fourth connector 4144, and the second antenna conductor 4175 may be provided with a second antenna connector coupled with the fourth connector 4144.

[0499] Fig.35 is a view showing another embodiment of a coupling module in which an antenna of a communicator is coupled to an aerosol generator.

[0500] like Fig.35 As shown in (a), the PCB 4140 may be provided with a first circuit 4154 connecting the communicator 400 and the first antenna 4130, a second circuit 4156 connecting the communicator 400 and the second antenna 4170, and a switch 4153 configured to control the opening and closing of the two circuits 4154 and 4156.

[0501] The circuits 4154 and 4156 and the switch 4153 may be implemented in various structures. Fig.35 (a) shows an example case of a first circuit 4154 and a second circuit 4156 , in which a circuit (communicator circuit) 4151 connected to the communicator 400 is branched into the first circuit 4154 and the second circuit 4156 at a switch 4153 .

[0502] The communicator circuit 4151 may have an amplifier (a low noise amplifier or a linear power amplifier) ​​4152. The first circuit 4154 may be provided with a first matching network 4155 for impedance matching, and the second circuit 4156 may be provided with a second matching network 4157.

[0503] Another embodiment is by Fig.35 The structure of (b) is disclosed. Fig.35 The implementation method of (b) is Fig.35 The embodiment of (c) is different in that the first circuit 4154 is provided with a first amplifier 4158 and a first matching network 4155 , and the second circuit 4156 is provided with a second amplifier 4159 and a second matching network 4157 .

[0504] for Fig.35 (a) and Fig.35 For the connection module 4100 in which the communicator is connected to the aerosol generator shown in (b), when the aerosol generating article 4200 is not inserted into the accommodating space 4112, the switch 4153 operates to close the first circuit 4154 (to connect the communicator to the first antenna) and disconnect the second circuit 4156 (to disconnect the communicator from the second antenna). On the other hand, when the article 4200 is inserted into the accommodating space 4112, the switch 4153 closes the second circuit 4156 (to connect the communicator to the second antenna) and disconnects the first circuit 4154 (to disconnect the communicator from the first antenna).

[0505] Therefore, according to an embodiment of the present disclosure, an antenna performing a wireless communication function can be selected from a plurality of antennas according to whether an aerosol generation function is performed, thereby minimizing deterioration of the wireless communication function due to a change in the dielectric constant of the mounting portion 4110.

[0506] The connection module 4100 having the above-mentioned communicator and aerosol generator can be installed in a mobile communication terminal. At this time, the antennas 4130 and 4170 provided in the connection module 4100 can be connected to the communicator 400 through antenna wires 4133 and 4175, and the heating part 4120 of the connection module 4100 can be connected to the controller 100 through the heating part line 4126.

[0507] The connection module 4100 having the communicator 400 and the control board 4160 may be included in the mobile communication terminal.

[0508] In the mobile communication terminal according to an embodiment, the communicator 400 and the control board 4160 may be mounted on the PCB 4140. At this time, the communicator 400 and the control board 4160 may be connected to the controller 100 through the third connector 4143 of the PCB.

[0509] The above-mentioned communication and aerosol generator, and the structure and control method of the communication terminal including the module are described in the embodiments of the present disclosure.

[0510] The above describes methods for heating an aerosol-generating article or a cigarette containing the aerosol-generating article. The heating methods are classified as internal heating or external heating depending on whether the heating is performed inside or outside the aerosol-generating article or cigarette.

[0511] For external heating, the cigarette can be heated by induction heating or by a capsule in the form of a patterned film. For internal heating, the cigarette can be heated directly by inserting a needle into the cigarette or using the needle as a receptor.

[0512] An embodiment in which an aerosol generator is positioned within a mobile communication terminal according to the above-mentioned heating type will be disclosed below, and system control may be finely performed by sensing the temperature of the aerosol generator.

[0513] When the temperature of the heating part of the aerosol generator is controlled, the temperature may be measured and sensed by directly attaching a temperature sensor to the inside or outside of the aerosol generator. In this case, the temperature sensor may be damaged. To avoid damage, a non-contact temperature sensor may be provided outside the heating part. However, in this case, power efficiency may be reduced.

[0514] An embodiment of accurately measuring the temperature of an aerosol generator of a mobile communication terminal without damaging the sensor is disclosed below.

[0515] Fig.36 is a view schematically showing an embodiment of an aerosol generator.

[0516] The aerosol generator 5100 of the mobile communication terminal may generate aerosol by heating the cigarette contained in the aerosol generator 5100 through induction heating. Induction heating may refer to a method of generating heat from a magnetic member by applying an alternating magnetic field having a periodically changing direction to the magnetic member configured to generate heat through an external magnetic field.

[0517] When an alternating magnetic field is applied to a magnetic member, the magnetic member may suffer energy loss such as eddy current loss and hysteresis loss, and the lost energy may be emitted from the magnetic member in the form of heat energy. As the amplitude or frequency of the alternating magnetic field applied to the magnetic member increases, the heat energy emitted from the magnetic member may increase.

[0518] The aerosol generator 5100 may cause heat energy to be emitted from the magnetic member by applying an alternating magnetic field to the magnetic member, and the aerosol generator 5100 may transfer the heat energy emitted from the magnetic member to the cigarette.

[0519] The magnetic member that generates heat due to the external magnetic field may be a susceptor 5110. The susceptor 5110 may be formed in the shape of a slice, a sheet, or a strip.

[0520] The susceptor 5110 may include metal or carbon. The susceptor 5110 may include at least one of ferrite, ferromagnetic alloy, stainless steel, and aluminum (Al).

[0521] The susceptor 5110 may also include at least one of graphite, molybdenum, silicon carbide, niobium, nickel alloys, metal films, ceramics such as zirconium oxide, transition metals such as nickel (Ni) or cobalt (Co), or semi-metals such as boron (B) or phosphorus (P).

[0522] The aerosol generator 5100 may include an accommodation space 5120 for accommodating a cigarette. The accommodation space 5120 may include an opening formed to be opened outside the accommodation space 5120 to accommodate the cigarette in the aerosol generator 5100. The cigarette may be accommodated in the aerosol generator 5100 through the opening of the accommodation space 5120 in a direction from the outside of the accommodation space 5120 to the inside of the accommodation space 5120.

[0523] like Fig.36 As shown in (a), a sensor 5110 can be set at the inner end of the accommodating space 5120, the sensor 5110 can be attached to the bottom surface formed at the inner end of the accommodating space 5120, the cigarette can be installed on the sensor 5110 from the upper end of the sensor 5110, and the cigarette can be received until the bottom of the accommodating space 5120.

[0524] like Fig.36 As shown in (b), the aerosol generator 5100 may not include the susceptor 5110, in which case the susceptor 5110 may be included in the cigarette.

[0525] The aerosol generator 5100 may include a coil unit 5130 that applies an alternating magnetic field to the susceptor 5110, and a resonant frequency changes in response to a temperature change of the susceptor 5110 caused by induction heating of the susceptor 5110. The coil unit 5130 may include at least one coil.

[0526] The coil may be implemented as a solenoid. The coil may be a solenoid wound along the side surface of the accommodation space 5120, and the cigarette 5200 may be accommodated in the inner space of the solenoid. The material of the conductor constituting the solenoid may be copper (Cu).

[0527] However, the conductor is not limited thereto. Silver (Ag), gold (Au), aluminum (Al), tungsten (W), zinc (Zn), and nickel (Ni), or an alloy including at least one of them, may be used as a material for the conductor constituting the solenoid that has a low resistivity and allows a large current to flow.

[0528] The coil unit 5130 may be wound along the outer lateral surface of the accommodation space 5120, and the coil unit 5130 may be disposed at a position corresponding to the susceptor 5110. The coil arrangement of the coil unit 5130 will be described in detail below.

[0529] The aerosol generator 5100 may supply power to the coil unit 5130 from a power supply unit of the mobile communication terminal.

[0530] The power supply unit 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, or the like.

[0531] The controller may control power supplied to the coil unit 5130. When the coil unit 5130 includes a plurality of coils, the controller may change a driving frequency of the coils.

[0532] The controller may inductively heat the susceptor 5110 by controlling the driving frequency. In addition, the controller may sense the resonant frequency of the coil changed due to the inductive heating of the susceptor 5110, and calculate the temperature of the susceptor based on the sensed resonant frequency.

[0533] An implementation in which the controller senses the resonant frequency will be described in detail below.

[0534] Fig.37 is a diagram showing an example of an aerosol generating article or cigarette that can be coupled to an aerosol generator of a mobile communication terminal.

[0535] Cigarette 5200 may include a tobacco rod 5210 and a filter rod 5220. Fig.37 The filter rod 5220 shown in FIG. 5 is composed of a single region, but is not limited thereto. The filter rod 5220 may include multiple sections.

[0536] For example, the filter rod 5220 may include: a first section to cool the aerosol; and a second section to filter specific components contained in the aerosol.

[0537] The filter rod 5220 may also include at least one section for performing another function.

[0538] The cigarette 5200 may be packaged by at least one packing member 5240. The packing member 5240 may be provided with at least one hole through which external air flows in or through which internal air flows out.

[0539] For example, cigarette 5200 can be packaged in a packaging member 5240.

[0540] For another example, the cigarette 5200 may be packaged in an overlapping manner by two or more packages 5240. Specifically, the tobacco rod 5210 may be packaged by a first package, and the filter rod 5220 may be packaged by a second package. The tobacco rod 5210 and the filter rod 5220 packaged by each package in the package may be combined, and the entire cigarette 5200 may be packaged by a third package.

[0541] The tobacco rod 5210 may include an aerosol-generating substance. For example, the aerosol-generating substance may include, but is not limited to, at least one of glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. The tobacco rod 5210 may include other additives, such as flavoring agents, humectants, and / or organic acids.

[0542] Flavoring agents may be added to the tobacco rod 5210 by spraying the tobacco rod 5210 with a flavoring agent such as menthol or a humectant.

[0543] The tobacco rod 5210 can be manufactured in various ways. For example, the tobacco rod 5210 can be formed by a sheet or a filament. Alternatively, the tobacco rod 5210 can be formed by a tobacco sheet cut into small pieces.

[0544] like Fig.37 As shown in (b), the cigarette 5200 may further include a sensor 5110. In this case, the sensor 5110 may be disposed in the tobacco rod 5210, such as Fig.37 The sensor 5110 may extend from one end of the tobacco rod 5210 to the filter rod 5220 .

[0545] The tobacco rod 5210 may be surrounded by a heat conductive material. For example, the heat conductive material may be a metal foil, such as an aluminum foil, but is not limited thereto. The heat conductive material surrounding the tobacco rod 5210 may evenly distribute the heat transferred to the tobacco rod 5210 to increase the thermal conductivity applied to the tobacco rod 5210, thereby enhancing the flavor of the aerosol.

[0546] The filter rod 5220 may be a cellulose acetate filter. The filter rod 5220 may be formed in various shapes. For example, the filter rod 5220 may be a cylindrical cigarette rod or a tubular cigarette rod including a hollow formed in the tubular cigarette rod. Alternatively, the filter rod 220 may be a concave rod including a cavity formed therein.

[0547] When the filter rod 5220 includes multiple sections, the multiple sections can be formed into different shapes.

[0548] The filter rod 5220 may be formed such that a flavor is generated from the filter rod 5220 .

[0549] For example, a flavored liquid may be sprayed onto the filter rod 5220 and separate fibers to which the flavored liquid is applied may be inserted into the filter rod 5220.

[0550] The filter rod 5220 may include at least one capsule 5230. The capsule 5230 may generate a flavor and may generate an aerosol. For example, the capsule 5230 may be formed into a structure in which a liquid containing a flavor is surrounded by a film.

[0551] The capsule 5230 may have a spherical or cylindrical shape, but is not limited thereto.

[0552] When the filter rod 5220 includes a cooling section for cooling the aerosol, the cooling section can be made of a polymer material or a biodegradable polymer material. For example, the cooling section can be made entirely of pure polylactic acid.

[0553] Alternatively, the cooling section may be made of a cellulose acetate filter including a plurality of perforations. However, the embodiment is not limited thereto. The cooling section may be composed of a structure and material that cools the aerosol.

[0554] Fig.38 An example of inserting a cigarette into an aerosol generator of a mobile communication terminal is shown.

[0555] Fig.38 (a) shows an example of a cigarette 5200 inserted into an aerosol generator 5100 when a susceptor 5110 is provided in the aerosol generator 5100.

[0556] Fig.38 (b) shows an example of the cigarette 5200 inserted into the aerosol generator 5100 when the susceptor 5110 is provided in the cigarette 5200 .

[0557] First, refer to Fig.38 (a), the cigarette 5200 may be accommodated in the accommodation space along the longitudinal direction of the cigarette 5200. The susceptor 5110 may be inserted into the cigarette 5200 accommodated in the aerosol generator 5100.

[0558] When the cigarette 5200 is assembled on the susceptor 5110, the tobacco rod 5210 may contact the susceptor 5110. The susceptor 5110 may extend in the longitudinal direction of the aerosol generator 5100 so as to be inserted into the cigarette 5200.

[0559] The susceptor 5110 may be disposed at a central portion of the accommodation space 5120 so as to be inserted into a central portion of the cigarette 5200 .

[0560] Although Fig.38 (a) of Fig.38 shows a single receptor 5110 being provided, embodiments are not limited thereto. In other words, the aerosol generator of the present disclosure may include a plurality of receptors 5110 extending in the longitudinal direction of the aerosol generator, and these receptors 5110 are arranged parallel to each other such that the receptors can be inserted into the cigarette 5200.

[0561] The coil unit 5130 may include at least one coil. The coil may be wound around the outer lateral surface of the accommodation space 5120 to extend in the longitudinal direction. The coil extending in the longitudinal direction may be provided on the outer lateral surface of the accommodation space 5120. The coil may extend in the longitudinal direction for a length corresponding to the receptor 5110, and the coil may be provided at a position corresponding to the receptor 5110.

[0562] Referring Fig.38 to (b) of Fig.38 , the cigarette 5200 may be accommodated in the accommodation space 5120 in the longitudinal direction of the cigarette 5200. When the cigarette 5200 is inserted into the accommodation space 5120, the receptor 5110 may be surrounded by the coil unit 5130.

[0563] The receptor 5110 may be provided at the central portion of the tobacco rod 5210 for uniform heat transfer. Although Fig.38 (b) of Fig.38 shows a single receptor 5110 being provided, embodiments are not limited thereto.

[0564] In other words, the aerosol generator 5100 of the present disclosure may include a plurality of receptors 5110 provided in the cigarette 5200.

[0565] The coil unit 5130 may include at least one coil. The coil may be wound around the outer lateral surface of the accommodation space 5120 to extend in the longitudinal direction. The coil extending in the longitudinal direction may be provided on the outer lateral surface of the accommodation space 5120. The coil may extend in the longitudinal direction for a length corresponding to the receptor 5110, and the coil may be provided at a position corresponding to the receptor 5110.

[0566] Fig.39 Examples of methods for winding coils in the aerosol generator are shown.

[0567] Fig.39 (a) of Fig.39 shows a coil winding method used when the coil unit 5130 includes only one coil, Fig.39 and (b) of Fig.39 and Fig.39 (c) of Fig.39 show coil winding methods used when the coil unit 5130 includes a plurality of coils.

[0568] Although Fig.39The case where a cigarette including a susceptor 5110 is accommodated in the accommodation space of the aerosol generator 5100 is shown, and even in the case where the susceptor 5110 is fixedly provided in the aerosol generator 5100 in the form of a needle, the following embodiments are also applicable.

[0569] exist Fig.39 (a) Fig.39 (b) and Fig.39 In (c), the inner lateral surface of the accommodating space 5120 refers to the area in contact with the area where the cigarette 5200 is inserted, and the outer lateral surface of the accommodating space 5120 refers to the side away from the inner lateral surface. The longitudinal direction of the aerosol generator may refer to a direction perpendicular to the end surface of the accommodating space into which the cigarette 5200 is inserted.

[0570] refer to Fig.39 (a), the coil unit 5130 may include a first coil 5131. The first coil 5131 may surround an outer lateral surface of the accommodation space.

[0571] The first coil 5131 may be wound around the outer lateral surface of the accommodating space along the longitudinal direction of the aerosol generator 5100 .

[0572] The first coil 5131 may be wound around the outer lateral surface of the accommodation space in the longitudinal direction to correspond to the susceptor 5110 .

[0573] exist Fig.39 In (a), the aerosol generator 5100 includes only one coil, so the first coil 5131 can be referred to as coil 5131.

[0574] In the case where the aerosol generator 5100 utilizes only one coil 5131 to inductively heat the susceptor 5110 and measure the temperature of the susceptor 5110, as shown in FIG. Fig.39 As shown in (a), the convenience of manufacturing can be improved.

[0575] exist Fig.39 In (b), the coil unit 5130 may further include a second coil 5132. The first coil 5131 and the second coil 5132 may be alternately wound around the outer lateral surface of the accommodating space along the longitudinal direction.

[0576] exist Fig.39 In (c), the coil unit 5130 may further include a second coil 5132. The first coil 5131 may be wound around a first region 5171 on the outer lateral surface of the accommodation space 5120, and the second coil 5132 may be wound around a second region 5172 different from the first region.

[0577] When the aerosol generator 5100 includes Fig.39When the multiple coils 5131 and 5132 are shown in (b) and (c) of 39, the aerosol generator 5100 can continuously heat the receptor 5110 through the first coil 5131, and at the same time measure the temperature of the receptor 5110 in real time through the second coil 5132.

[0578] A detailed implementation of measuring the temperature of the sensor 5110 in real time will be disclosed below.

[0579] Fig.40 is a flow chart illustrating an example of measuring the temperature of a heating portion of an aerosol generator.

[0580] In the above-disclosed embodiment of the aerosol generator, the temperature of the heating portion may be measured as follows.

[0581] In operation S910, when power is supplied to the aerosol generator or a cigarette is sensed to be inserted into the aerosol generator, the controller of the mobile communication terminal may cause the aerosol generator to drive the first coil 5131 within a first frequency range.

[0582] For example, when the first coil 5131 is driven within the first frequency range, the current applied to the first coil 5131 is maximized at the first resonant frequency.

[0583] In other words, the current may vary according to the driving frequency applied to the coil, and the controller may control the aerosol generator based on information about the frequency response characteristics. This will be described in detail below with reference to the accompanying drawings showing the relationship between the applied frequency and the frequency response characteristics of the coil.

[0584] In operation S920, the controller may sense a change in the resonant frequency of the second coil based on the second frequency range.

[0585] The frequency response of the second coil may change from a first frequency response to a second frequency response when the temperature of the susceptor changes.

[0586] As the temperature of the susceptor changes, the controller may cause a second resonant frequency of the second coil to be sensed within a second frequency range.

[0587] The controller may sense the change in the resonant frequency according to the temperature change of the susceptor in the aerosol generator using a detection sensor in the aerosol generator or an NFC antenna of the mobile communication terminal.

[0588] The NFC antenna may include a loop antenna module including a loop coil. The loop antenna module of the NFC antenna of the mobile communication terminal according to the present embodiment may sense a frequency according to a temperature change of a susceptor heated by magnetic induction.

[0589] The relationship between the resonance frequency and the response characteristics according to the temperature change of the sensor will be described in detail with reference to the accompanying drawings.

[0590] In operation S930, the controller may calculate the temperature of the sensor based on the change in the resonance frequency of the second coil.

[0591] As the temperature of the sensor changes, the controller may calculate the temperature of the sensor based on the difference in the frequency response characteristics.

[0592] The controller may use a frequency detection sensor in the aerosol generator or the NFC antenna of the mobile communication terminal to sense the frequency difference and calculate the temperature of the sensor based on the difference.

[0593] If there is a difference in the frequency characteristics according to the temperature of the sensor heated by magnetic induction in the aerosol generator, the loop antenna coil of the NFC antenna receives the corresponding frequency response characteristics and provides information about the response characteristics to the controller.

[0594] Therefore, the controller may control the temperature of the sensor in the aerosol generator by changing the drive frequency applied to the coil for aerosol generation.

[0595] A specific example of the logic for the controller to calculate the temperature of the sensor based on the frequency response characteristics of the coil will be described in detail below with reference to the accompanying drawings related to the difference in the resonance frequency and the change in the frequency response characteristics.

[0596] Fig.41 is a graph depicting the relationship between the drive frequency applied to the coil and the frequency response characteristics.

[0597] In this graph, the horizontal axis represents the frequency and the vertical axis represents the intensity of the frequency signal.

[0598] The current applied to the first coil 5131 may depend on the first drive frequency for driving the first coil 5131.

[0599] When assuming that the frequency response characteristics of the first coil 5131 are maximized at the first resonance frequency fo1, the current applied to the first coil 5131 may be maximized at the first resonance frequency fo1.

[0600] The first resonance frequency fo1 may be determined by the first coil 5131 and the first capacitor connected in series with the first coil 5131.

[0601] In addition, based on the first resonance frequency fo1, the response characteristics of the first coil 5131 may gradually decrease as the frequency increases.

[0602] For example, the amplitude h1 of the response characteristic of the first coil 5131 at a first frequency f1 higher than the first resonance frequency fo1 may be greater than the amplitude h2 of the response characteristic of the first coil 5131 at a second frequency f2 higher than the first frequency f1.

[0603] The controller may control the current applied to the first coil 5131 by changing the first driving frequency within a preset first frequency range.

[0604] When the current applied to the first coil 5131 varies, the temperature of the susceptor 5110 provided in the aerosol generator may also vary.

[0605] The aerosol generating article may be the above-mentioned cigarette. For example, the controller may supply maximum power to the first coil 5131 by setting the first driving frequency to the first resonant frequency fo1. Thus, the susceptor 5110 may be heated to a maximum temperature.

[0606] As another example, the controller may supply the first power, which is smaller than the maximum power, to the first coil 5131 by setting the first driving frequency to a first frequency f1 which is higher than the first resonance frequency fo1.

[0607] Thus, the susceptor 5110 may be heated to a first temperature that is lower than the maximum temperature.

[0608] As another example, the controller may supply a second power smaller than the first power to the first coil 5131 by setting the first driving frequency to a second frequency f2 higher than the first frequency f1. Thus, the susceptor 5110 may be heated to a second temperature lower than the first temperature.

[0609] Fig.42 : is a graph showing the relationship between the change in resonance frequency and the response characteristic according to the temperature change of the susceptor.

[0610] Specifically, Fig.42 The frequency responses 1120 , 1110 , 1130 of the second coil 5132 as a function of the temperature change of the susceptor 5110 are depicted.

[0611] When the susceptor 5110 is at the first temperature, the response characteristic of the second coil 5132 may be maximized at the second resonant frequency fo2. The second resonant frequency fo2 may be determined by the second coil 5132 and a second capacitor connected in series with the second coil 5132.

[0612] In addition, as the temperature of the susceptor 5110 increases, the second resonant frequency fo2 of the second coil 5132 may increase according to Fo2" or decrease according to Fo2'.

[0613] As the second resonant frequency fo2 changes, the frequency of the output maximum current may also change. The controller 5150 may scan the second driving frequency of the second coil 5132 within the second frequency range, and obtain information of sensing the second resonant frequency fo2 of the second coil 5132 based on the result of the frequency scanning.

[0614] For example, the controller 5150 may sweep the second driving frequency of the second coil within the second frequency range, and determine the driving frequency at the maximum current applied to the second coil 5132 as the second resonant frequency.

[0615] When the second frequency range overlaps the first frequency range, the susceptor 5110 may be inductively heated by the second coil 5132. Since the heating by the second coil 5132 corresponds to accidental heating, it may cause inaccurate temperature control of the susceptor 5110. Therefore, the second resonant frequency fo2 may be set lower than the first resonant frequency fo1.

[0616] In addition, the second frequency range may be set differently 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. In another example, at the lower limit of the first frequency range, the temperature of the susceptor 5110 may be increased to a first heating temperature. At the upper limit of the second frequency range, the temperature of the susceptor 5110 may be increased to a second heating temperature lower than the first heating temperature. The second heating temperature may be a temperature at which no aerosol is generated.

[0617] 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 also change even during the frequency sweep of the second coil 5132. Therefore, the upper limit of the second frequency range may be set to a frequency that does not affect the temperature change of the susceptor 5110. For example, when the first frequency range is 2 MHz to 4 MHz, the second frequency range may be set to, for example, 0.1 MHz to 0.3 MHz, but the present disclosure is not limited thereto.

[0618] Fig.43 It is a graph showing the difference in resonance frequency and the change in frequency response characteristics.

[0619] Specifically, the figure shows frequency responses 1210 and 1220 of the second coil 5132 according to the temperature change of the susceptor 5110. As the temperature of the susceptor 5110 changes, the frequency response of the second coil 5132 changes from the first frequency response 1210 to the second frequency response 1220.

[0620] The controller may calculate the temperature of the susceptor 5110 based on a frequency difference fo2d between the third resonant frequency fo2a of the second coil sensed at a first time after the susceptor 5110 starts heating and the fourth resonant frequency fo2b at a second time, the second time being a preset time later than the first time.

[0621] The controller may calculate the temperature of the susceptor 5110 according to the matching data of the resonant frequency difference fo2d and the temperature of the susceptor 5110. The matching data related to the resonant frequency difference fo2d and the temperature of the susceptor 5110 may be pre-stored in the memory of the storage device 800 in the form of a lookup table.

[0622] Fig.44 A flow chart of another example of a method of operating an aerosol generator and a schematic diagram of a control cycle of an aerosol generator are shown.

[0623] Fig.44 (a) is a flowchart showing another example of an operation method of the aerosol generator, in which the aerosol generator 200 heats the susceptor 5110 using only one coil and the aerosol generator 200 calculates the temperature of the susceptor 5110 .

[0624] Fig.44 (b) shows that according to Fig.44 The control cycle of the flowchart disclosed in (a) is shown in FIG.

[0625] The controller 100 may control the coil of the aerosol generator within a preset control cycle. Each control cycle may include a heating cycle and a sensing cycle. The controller 100 may use the coil of the aerosol generator to heat the aerosol generating article or the receiver 5110 during the heating cycle, and the controller 100 may use the coil to calculate the temperature of the receiver 5110 during the sensing cycle.

[0626] Specifically, in operation S1310, the controller 100 may drive the coil of the aerosol generator based on the first frequency range during a heating period.

[0627] The method of driving the coil of the aerosol generator during the heating cycle can be the same as described above. The controller 100 can control the current applied to the coil of the aerosol generator by changing the driving frequency within a preset frequency range. When the current applied to the coil of the aerosol generator changes, the temperature of the aerosol generating article or the susceptor 5110 may also change.

[0628] In operation S1320, the controller 100 may sense a change in the resonance frequency of the coil of the aerosol generator based on the second frequency range in the sensing period.

[0629] The method of sensing the change of the resonant frequency of the coil 5131 in the sensing period can be similar to the sensing method exemplarily described above. The controller 100 can scan the driving frequency of the coil of the aerosol generator within the second frequency range, and the controller 100 senses the resonant frequency of the coil of the aerosol generator based on the result of the frequency scanning.

[0630] For example, the controller 100 may scan the driving frequency of the coil of the aerosol generator within the second frequency range, and determine the driving frequency at the maximum current applied to the coil of the aerosol generator as the resonant frequency.

[0631] In this embodiment, the controller uses only one coil in the aerosol generator to heat the susceptor 5110 and calculates the temperature of the susceptor 5110. Therefore, the first frequency range and the second frequency range can be set to be the same. For example, the first frequency range and the second frequency range can be set to 2MHz to 4MHz, but are not limited thereto.

[0632] The heating period may be set to be longer than the sensing period. By setting the heating period to be longer than the sensing period, the controller can accurately measure the temperature of the susceptor 5110 while minimizing the temperature variation of the susceptor 5110.

[0633] In operation S1330, the controller 100 may calculate the temperature of the susceptor 5110 based on a change in the resonance frequency of the coil of the aerosol generator.

[0634] The method of calculating the temperature of the susceptor 5110 during the sensing period can be similar to the method used above given two coils.

[0635] The controller 100 may calculate the temperature of the susceptor 5110 based on a frequency difference between the fifth resonant frequency of the coil 5131 sensed at a first time after the sensing period starts and the sixth resonant frequency at a second time, the second time being a preset time later than the first time.

[0636] The controller 100 may calculate the temperature of the susceptor 5110 based on matching data related to the resonant frequency difference and the temperature of the susceptor 5110. The matching data related to the resonant frequency difference and the temperature of the susceptor 5110 may be pre-stored in the storage device 800 in the form of a lookup table.

[0637] Fig.45 is a block diagram of an example of a mobile communication terminal that can conveniently control the temperature of an aerosol generator and a system.

[0638] refer to Fig.45 , the mobile communication terminal according to the embodiment may include a controller 100 , an aerosol generator 200 , a power supply unit 300 , and a storage device 800 .

[0639] Although not shown in this figure, the susceptor is included in the aerosol generator 200 or a cigarette coupled to the aerosol generator 200 .

[0640] The power supply unit 300 may supply power to the internal components of the aerosol generator 200. The power supply unit 300 may provide direct current, and a power converter (not shown) of the aerosol generator 200 may convert the direct current provided by the power supply unit 300 into alternating current and supply the alternating current to the aerosol generator 200. The aerosol generator 200 may heat the susceptor by magnetic induction according to the alternating current.

[0641] The heating portion of the aerosol generator 200 may include at least one coil. In one embodiment, the heating portion of the aerosol generator 200 may include a first coil.

[0642] In another embodiment, the heating portion of the aerosol generator 200 may include a first coil 5131 and a second coil 5132 .

[0643] The heating portion of the aerosol generator 200 may also include a capacitor connected in series or in parallel with the coil. In one embodiment, the heating portion of the aerosol generator 200 may include a first capacitor connected in series or in parallel with the first coil.

[0644] In another embodiment, the heating portion of the aerosol generator 200 may include a first capacitor connected in series or in parallel with the first coil and a second capacitor connected in series or in parallel with the second coil. In the following description, it is assumed that the capacitor is connected in series with the coil. However, even if the capacitor is connected in parallel with the coil, the following description is also applicable.

[0645] The controller 100 may control the driving frequency of the heating portion of the aerosol generator 200. In the series resonant circuit, the current flowing through the first coil and / or the second coil (if the second coil is present) may be maximized at the resonant frequency. The controller 100 may heat the susceptor of the aerosol generator 200 by controlling the driving frequency of the heating portion of the aerosol generator 200, and the controller 100 may obtain information about the temperature of the susceptor using a frequency detection sensor.

[0646] The frequency detection sensor may use the NFC antenna of the communicator 400 , or the frequency detection sensor may include a detection sensor in the aerosol generator 200 .

[0647] The controller 100 may obtain information related to a change in the resonance frequency according to a temperature change of the susceptor in the aerosol generator 200 from a frequency detection sensor, for example, an NFC antenna of the communicator 400 .

[0648] The controller 100 heats the susceptor through the first coil, and the controller 100 may obtain information corresponding to the temperature change of the susceptor through the NFC antenna or a separate frequency detection sensor according to the change in the resonant frequency of the second coil. Alternatively, the controller 110 may heat the susceptor only through the first coil, and obtain resonant frequency change information corresponding to the temperature of the susceptor through the NFC antenna or a separate frequency detection sensor.

[0649] The storage device 800 may store matching data related to the resonance frequency and the susceptor temperature or matching data related to the resonance frequency change and the susceptor temperature in the form of a lookup table, and the controller 100 may calculate the temperature of the susceptor based on the lookup table.

[0650] The controller 100 may reliably control the entire system of the mobile communication terminal including the aerosol generator 200 based on the calculated temperature, including proportional integral derivative (PID) control.

[0651] Examples in which the controller 100 controls the first coil and the second coil or controls the temperature using only the first coil 5131 have been described above in detail.

[0652] Another embodiment is disclosed below, in which the temperature of a receptor in an aerosol generator of a mobile communication terminal can be sensed to control a system of the mobile communication terminal.

[0653] In one embodiment, the susceptor may be heated by controlling the alternating current supplied to the coil unit.

[0654] In another embodiment, the susceptor may be heated by controlling the alternating current supplied to the first coil, and then the direct current supplied to the first coil may be controlled to induce a change in the magnetic properties of the susceptor, thereby calculating the temperature of the susceptor.

[0655] In another embodiment, the susceptor may be heated by controlling the alternating current supplied to the first coil, and then the direct current supplied to the second coil may be controlled to induce a change in the magnetic properties of the susceptor, thereby calculating the temperature of the susceptor.

[0656] The mobile communication terminal may sense the magnetic change within the coil using a magnetic sensor of the aerosol generator or a magnetic sensor in a sensor in the mobile communication terminal.

[0657] Based on the sensed magnetic changes, the controller of the mobile communication terminal can calculate the temperature of the receptor and control the system. A detailed implementation of the operation is disclosed below.

[0658] Fig.46 An embodiment of a method of winding a coil in an aerosol generator is shown.

[0659] Although Fig.46 It is shown that the cigarette including the susceptor 5110 is accommodated in the accommodation space in the aerosol generator 5100, but the embodiments disclosed below are applicable even in the case where the susceptor 5110 is fixed to the aerosol generator 5100 in the form of a needle or the like.

[0660] Fig.46 (a) shows a coil winding method used when the coil unit 5130 includes only one coil, Fig.46 (b) and Fig.46 (c) shows a coil winding method adopted when the coil unit 5130 includes a plurality of coils.

[0661] The magnetic sensor can sense the changes in the magnetic field of the receptor.

[0662] Here, the magnetic sensor may be separately provided in the aerosol generator, and the magnetic sensor may also refer to a magnetic sensor in a sensor in a mobile communication terminal or a magnetic sensor in a camera module.

[0663] For simplicity, this embodiment shows that the magnetic sensor is provided in the aerosol generator. However, the same embodiment can also be applied when a magnetic sensor in a sensor in a mobile communication terminal or a magnetic sensor in a camera module in an input unit is used. Here, they are similarly referred to as magnetic sensors.

[0664] The magnetic sensor may include at least one Hall sensor, and the controller may measure the temperature of the receptor according to a change in magnetic force sensed by the magnetic sensor.

[0665] The Hall sensor measures the magnitude of the magnetic field based on the mutually orthogonal voltage (Hall voltage) generated by the current in the coil and the magnetic field. Therefore, when the magnetic sensor measures the magnetic change in the aerosol generator due to magnetic induction, the controller can receive information corresponding to the corresponding temperature of the receptor to perform control operations.

[0666] exist Fig.46 In (a), the coil unit 5131 includes a coil wound around the outer lateral surface of the accommodating space along the longitudinal direction of the aerosol generator 5100.

[0667] The controller may control the alternating current in the coil unit 5131 to heat the susceptor 5110 and induce a change in magnetic properties.

[0668] As another example, the controller may heat the susceptor 5110 by controlling the alternating current supplied to the coil unit 5131 , and the controller may induce magnetism in the susceptor 5110 by controlling the direct current supplied to the coil unit 5131 .

[0669] The magnetic sensor can sense the magnetism induced in the receptor 5110 and transmit information related to the induced magnetism to the controller, and the controller can calculate and control the temperature of the receptor 5110 according to the changing magnetism.

[0670] exist Fig.46 In (b), the coil unit 5130 includes a first coil 5131 and a second coil 5132 alternately wound around the outer lateral surface of the accommodating space in the longitudinal direction.

[0671] exist Fig.46 In (c), the coil unit 5130 includes a first coil 5131 wound around a first area 5171 on the outer lateral surface of the accommodating space 5120, and a second coil 5132 wound around a second area 5172 on the outer lateral surface different from the first area.

[0672] In this case, the controller may heat the susceptor 5110 by controlling the alternating current supplied to the first coil 5131 , and induce magnetism in the susceptor 5110 by controlling the direct current supplied to the second coil 5132 .

[0673] The magnetic sensor may sense magnetism induced in the susceptor 5110 and transmit information related to the induced magnetism to the controller, and the controller may calculate and control the temperature of the susceptor 5110 based on the changed magnetism.

[0674] Fig.47 The changes in magnetic force and output voltage due to the temperature change of the receptor are plotted.

[0675] Fig.47 (a) depicts the change of magnetic force 5291 caused by the temperature of the receptor. The horizontal axis represents temperature and the vertical axis represents magnetic force. As shown in the figure, as the temperature of the receptor increases, the magnetic force decreases. The storage device 800 of the mobile communication terminal can store data representing the change of magnetic force with the temperature of the receptor in the form of a lookup table.

[0676] Therefore, the relationship between the change in the temperature of the receptor and the change in the magnetic force of the receptor can be determined. When the magnetic sensor senses the change in the magnetic force of the receptor, the magnetic sensor can output an output value corresponding to the magnetic force of the receptor. The output value can be set as voltage, current or frequency.

[0677] Fig.47(b) depicts an output voltage 5301 according to the magnetic force of the receptor. 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 as the magnetic force change value of the receptor increases, the output voltage also increases. Therefore, the storage device 800 of the mobile communication terminal can store the output value according to the magnetic force change as a lookup table. When the controller receives the output value from the magnetic sensor, the corresponding value of the magnetic force change of the receptor can be obtained according to the lookup table stored in the storage unit, and the temperature information about the receptor can be obtained accordingly.

[0678] Based on this information, the controller can control the temperature of the susceptor.

[0679] Fig.48 An example of using a coil to control the temperature of a susceptor in an aerosol generator of a mobile communication terminal is shown.

[0680] This figure is a flow chart showing a method of sensing the temperature of the susceptor 5110 according to a change in the magnetic force of the susceptor 5110 when the susceptor 5110 is formed of a permanent magnetic material.

[0681] When the susceptor 5110 is formed of a permanent magnetic material, it is not necessary to induce magnetism in the susceptor 5110. That is, the first coil 5131 of the aerosol generator is only used to heat the susceptor 5110.

[0682] Therefore, for simplicity, the first coil 5131 will be referred to as coil 5131.

[0683] In operation S1110, the controller 100 may inductively heat the susceptor 5110. The susceptor 5110 may be disposed in the aerosol-generating article or the aerosol generator 200. The aerosol-generating article may be the cigarette shown above, and the susceptor 5110 may be formed of a permanent magnetic material.

[0684] The controller 100 may control the AC power supplied to the coil 5131. When the AC power is supplied to the coil 5131, the direction of the magnetic field formed inside the coil 5131 may change periodically. When the susceptor 5110 is exposed to the AC magnetic field formed by the coil 5131, the susceptor 5110 may be inductively heated.

[0685] The controller 100 may control the temperature of the susceptor 5110 by changing the amplitude, frequency, etc. of the alternating current supplied to the coil 5131 according to a preset temperature curve.

[0686] In operation S1120 , the magnetic sensor may sense a change in magnetic force according to a temperature change of the receptor 5110 .

[0687] In one embodiment, the magnetic sensor may output a magnetic value corresponding to the temperature of the receptor 5110 as information such as voltage.

[0688] In operation S1130, the controller 100 may calculate the temperature of the receptor 5110 based on the magnetic force variation information output by the magnetic force sensor or acquire stored temperature information.

[0689] For example, the controller 100 may acquire the temperature of the receptor 5110 corresponding to the output value output by the magnetic sensor from a lookup table stored in the storage device 800 .

[0690] As another example, the controller 100 acquires a magnetic force difference between a first magnetic force of the susceptor 5110 sensed at a first time after the start of heating and a second magnetic force at a second time, the second time being a preset time later than the first time.

[0691] The controller 100 may also obtain the temperature of the receptor 5110 corresponding to the magnetic force difference from a lookup table stored in the storage device 800 .

[0692] Referring to the drawing, when the susceptor 5110 is formed of a permanent magnetic material, the susceptor 5110 has magnetism. Therefore, the controller 100 does not need to induce magnetism in the susceptor 5110.

[0693] In this case, the design of the aerosol generator 200 of the mobile communication terminal may be simpler, and the controller 100 of the mobile communication terminal may easily control the temperature of the aerosol generator 200 .

[0694] In embodiments where the susceptor 5110 is limited to a permanent magnet, many design considerations may arise due to the electrical or mechanical properties of the permanent magnet. Therefore, when the susceptor 5110 of the aerosol generator 200 of the present disclosure is not formed of a permanent magnetic material, the temperature of the susceptor 5110 can be measured by inducing magnetism in the susceptor 5110.

[0695] An embodiment of a method of measuring the temperature of the susceptor 5110 when the susceptor 5110 is not formed of a permanent magnetic material will be described below.

[0696] Fig.49 is a diagram showing a relationship between a control cycle and an interval according to an example of controlling a receptor of an aerosol generator.

[0697] The controller 100 may control the coil unit 5130 based on a preset control cycle. Each control cycle may include a first interval for heating the susceptor 5110 and a second interval for inducing magnetism in the susceptor 5110.

[0698] The controller 100 may heat the susceptor 5110 during the first interval and calculate the temperature of the susceptor 5110 during the second interval.

[0699] The controller 100 may inductively heat the susceptor 5110 using only the first coil 5131 and induce magnetism in the susceptor 5110. Alternatively, the controller 100 may heat the susceptor 5110 using the first coil 5131 and induce magnetism in the susceptor 5110 using the second coil 5132.

[0700] A method in which the controller 100 measures the temperature of the susceptor 5110 using only the first coil 5131 and a method in which the controller 100 measures the temperature of the susceptor 5110 using the first coil 5131 and the second coil 5132 will be described in detail below.

[0701] Fig.50 An example of controlling the susceptor when the coil unit of the aerosol generator is configured as a single coil unit is shown.

[0702] See also Fig.50 In operation S1310, the controller 100 may inductively heat the susceptor 5110 using the coil 5131 during the first interval. The inductive heating of the susceptor 5110 using the coil 5131 during the first interval may be the same as the inductive heating disclosed above. That is, the controller 100 may control the alternating current supplied to the coil 5131 during the first interval.

[0703] When alternating current is supplied to the coil 5131, the direction of the magnetic field formed inside the coil 5131 may change periodically. When the susceptor 5110 is exposed to the alternating magnetic field formed by the coil 5131, the susceptor 5110 may be inductively heated.

[0704] The susceptor 110 may be disposed in a cigarette or an aerosol generator 200, which is an aerosol generating article.

[0705] The controller 100 may control the temperature of the susceptor 5110 by changing the amplitude, frequency, etc. of the alternating current supplied to the coil 5131 according to a preset temperature curve.

[0706] In operation S1320, the controller 100 may sense the magnetism of the susceptor 5110 through the coil during the second interval.

[0707] The controller 100 may control the direct current supplied to the coil 5131 during the second interval. When the direct current is supplied to the coil 5131, a magnetic field may be formed outside the coil 5131. When the susceptor 5110 is exposed to the magnetic field, a magnetic moment reacts inside the susceptor 5110, so that the susceptor 5110 may be magnetized.

[0708] In operation S1330, the magnetic sensor may sense a change in magnetic force according to a temperature change of the receptor 5110 within the second interval.

[0709] The method of sensing the magnetic force of the receptor 5110 in the second interval may be the same as the magnetic force sensing method disclosed above. That is, the magnetic sensor may output a magnetic force value corresponding to the temperature of the receptor 5110 in the form of voltage.

[0710] The first interval may be set to be longer than the second interval. In this case, the temperature of the susceptor 5110 may be accurately measured while minimizing the temperature variation of the susceptor 5110.

[0711] In operation S1340, the controller 100 may calculate the temperature of the susceptor 5110 based on the change in magnetic force.

[0712] The temperature calculation method of the controller 100 in the second interval may be the same as the temperature calculation method disclosed above. In other words, the controller 100 may obtain the temperature of the susceptor 5110 corresponding to the output value output by the magnetic sensor from the lookup table stored in the storage device 800. As another example, the controller 100 obtains the magnetic force difference between the first magnetic force of the susceptor 5110 sensed at the first time after the start of heating and the second magnetic force at the second time, the second time being a preset time later than the first time.

[0713] The controller 100 may also obtain the temperature of the receptor 5110 corresponding to the magnetic force difference from a lookup table stored in the storage device 800 .

[0714] Fig.51 An example of controlling the susceptor when the coil unit of the aerosol generator includes two or more coils is shown.

[0715] This figure is a flowchart showing a method of measuring the temperature of the susceptor 5110 by the first coil 5131 and the second coil 5132.

[0716] In operation S1410, the controller 100 may inductively heat the susceptor 5110 using the first coil 5131 within a first interval. The method of inductively heating the susceptor 5110 using the first coil 5131 within the first interval has been disclosed above. That is, the controller 100 may control the alternating current supplied to the first coil 5131 within the first interval.

[0717] When an alternating current is supplied to the first coil 5131, the direction of the magnetic field formed inside the first coil 5131 may change periodically. When the susceptor 5110 is exposed to the alternating magnetic field formed by the first coil 5131, the susceptor 5110 may be inductively heated. The susceptor 110 may be disposed in a cigarette or an aerosol generator 200.

[0718] The controller 100 may control the temperature of the susceptor 5110 by changing the amplitude, frequency, etc. of the alternating current supplied to the first coil 5131 according to a preset temperature curve.

[0719] In operation S1420, the controller 100 may induce magnetism in the susceptor 5110 using the second coil 5132 within a second interval.

[0720] The controller 100 may control the direct current supplied to the second coil 5132 within the second interval. At this time, the controller 100 may not supply power to the first coil 5131. When a direct current is supplied to the second coil 5132, a magnetic field may be formed outside the second coil 5132. When the susceptor 5110 is exposed to the magnetic field, the magnetic moment reacts inside the susceptor 5110, so the susceptor 5110 may be magnetized.

[0721] In operation S1430, the magnetic force sensor may sense a change in magnetic force according to a change in the temperature of the susceptor 5110 within the second interval.

[0722] The method of sensing the magnetic force of the susceptor 5110 in the second interval is the same as that disclosed above. That is, the magnetic force sensor may convert the magnetic force value corresponding to the temperature of the susceptor 5110 into a voltage and output the voltage.

[0723] The first interval may be set to be longer than the second interval. This is intended to accurately measure the temperature of the susceptor 5110 while minimizing the temperature change of the susceptor 5110.

[0724] In operation S1440, the controller 100 may calculate the temperature of the susceptor 5110 based on the change in magnetic force.

[0725] The temperature calculation method of the controller 100 in the second interval may be similar to that disclosed above. In other words, the controller 100 may obtain the temperature of the receptor 5110 corresponding to the output value output by the magnetic sensor from the lookup table stored in the storage device 800.

[0726] As another example, the controller 100 obtains a magnetic force difference between a first magnetic force of the susceptor 5110 sensed at a first time after the start of heating and a second magnetic force at a second time, the second time being a preset time later than the first time.

[0727] The controller 100 may also obtain the temperature of the receptor 5110 corresponding to the magnetic force difference from the lookup table stored in the storage device 800 .

[0728] As described above, the magnetic sensor may be separately provided in the aerosol generator, or the magnetic sensor may use a sensor of the mobile communication terminal or a magnetic sensor in a camera module.

[0729] Fig.52 An embodiment of a mobile communication terminal capable of conveniently controlling the temperature of an aerosol generator and the system is shown.

[0730] To facilitate description of the present embodiment, a block diagram is disclosed according to a logical configuration, and the disclosed blocks may correspond to the physical components disclosed above.

[0731] See also Fig.52 , the mobile communication terminal according to the embodiment may include a controller 100 , an aerosol generator 200 , a power supply unit 300 , a sensor 500 , and a storage device 800 .

[0732] Although not shown in the drawings, the susceptor is included in the aerosol generator 200 or a cigarette coupled to the aerosol generator 200 .

[0733] The coil unit of the aerosol generator 200 may include at least one coil. The coil unit may include a first coil and a second coil that are alternately wound or wound in different regions.

[0734] The power supply unit 300 may supply power to the internal component blocks of the aerosol generator 200. The power supply unit 300 may provide direct current, and a power converter (not shown) of the aerosol generator 200 may convert the direct current provided by the power supply unit 300 into alternating current and supply the alternating current to the aerosol generator 200. The aerosol generator 200 may heat the susceptor of the aerosol generator 200 by magnetic induction according to the alternating current.

[0735] The controller 100 may control power supplied to the coil of the aerosol generator 200 .

[0736] For example, the controller 100 may heat the susceptor by controlling the AC power supplied to the first coil. In another embodiment, the controller 100 may heat the susceptor by controlling the AC power supplied to the first coil, or induce magnetism in the susceptor by controlling the DC power supplied to the first coil.

[0737] In yet another embodiment, the controller 100 may heat the susceptor by controlling the alternating current supplied to the first coil, and induce magnetism in the susceptor by controlling the direct current supplied to the second coil.

[0738] When the controller 100 heats the susceptor of the aerosol generator 200 and induces magnetism, the magnetic force sensor or magnetic sensor of the sensor 500 may sense the change in magnetism of the susceptor of the aerosol generator 200 .

[0739] In an embodiment, the magnetic force sensor or magnetic sensor of the sensor 500 may be physically included in a complex sensor chip of the mobile communication terminal, or may be included in a camera module.

[0740] The controller 100 may calculate the temperature of the susceptor of the aerosol generator 200 according to the magnetic force change sensed by the magnetic sensor or the magnetic sensor. The relationship between the magnetic force change and the temperature of the susceptor has been disclosed above.

[0741] The storage device 800 may store matching data or a lookup table related to the relationship between the magnetic force variation of the receptor and the temperature.

[0742] The controller 100 may calculate the temperature of the susceptor based on the matching data and the lookup table stored in the storage device 800 .

[0743] Another embodiment of a system for sensing the temperature of a susceptor in an aerosol generator and controlling a mobile communication terminal based on the temperature is disclosed below.

[0744] Fig.53 is a block diagram showing a mobile communication terminal including an aerosol generator. In the following description, redundant descriptions of the above details will be omitted.

[0745] refer to Fig.53 , the mobile communication terminal may include a controller 100 , an aerosol generator 200 , a power supply unit 300 , a sensor 500 , and an output unit 700 .

[0746] As described above, the controller 100 may perform overall control operations related to the operation of the mobile communication terminal. In addition, the controller 100 may perform control operations related to aerosol generation by the aerosol generator 200. For example, the controller 100 may perform control operations such as controlling the power applied to the aerosol generator 200 and counting down (or counting) a counter related to the aerosol generator 200. In addition, the controller may control the performance of the display module 710, which is configured to generate outputs related to vision, hearing, or touch, and which is included in the output unit 700.

[0747] When a cigarette stick is accommodated, the aerosol generator 200 can generate an aerosol by heating the cigarette stick as described above. With respect to heating the cigarette stick, the aerosol generator 200 may include an external induction heater and an internally inserted induction heater, as described above with reference to Figures 4 to 27 Specifically, the aerosol generator 200 can be based on the above reference Figures 4 to 17 The external induction heater performs operations related to the generation of aerosol, and the external induction heater performs induction heating on the susceptor included in the cigarette rod.

[0748] The power supply unit 300 may include a rechargeable battery capable of supplying direct current power to the mobile communication terminal. The power supply unit 300 may be electrically connected to the aerosol generator 200 to supply direct current power to the aerosol generator 200.

[0749] As described above, the sensor 500 may include one or more sensors configured to sense at least one of information in the mobile communication terminal, information related to the surrounding environment around the mobile communication terminal, and user information. The sensor 500 may also include a sensor capable of sensing a voltage, a current, etc. of a component included in the mobile communication terminal.

[0750] As described above, when the aerosol generator 200 is based on an external induction heater, it is difficult to directly measure the temperature of a physically separated susceptor. Therefore, the controller 100 needs to use an indirect temperature measurement method to estimate the temperature of the susceptor in order to control the power to the aerosol generator 200.

[0751] Specifically, the controller 100 may estimate the temperature of the susceptor by considering the relationship between the equivalent resistance of the susceptor and the temperature. To this end, the sensor 500 may be configured to generate the first load information by respectively sensing the current, voltage, and power of the aerosol generator 200 among the components included in the mobile communication terminal. In this case, the controller 100 may acquire the first load information from the sensor 500, and indirectly estimate the temperature of the susceptor by estimating the equivalent resistance of the susceptor based on the first load information. The controller 100 may control the power applied to the aerosol generator 200 based on the estimated susceptor temperature.

[0752] Alternatively, the mobile communication terminal or the controller 100 may also consider the change of the resonance frequency (see Figure 36 to Figure 45 ), changes in magnetism (see Figures 46 to 52 ) and changes in receptor properties (see Figures 57 to 60 ) to measure or estimate the temperature of the receptor or aerosol generator 200. Alternatively, for example, the controller 100 may directly measure or estimate the temperature of the receptor or aerosol generator 200 by a sensor (included in the sensor) configured to sense the temperature of the included display module 710. Alternatively, the controller 100 may calculate or estimate the change in the characteristic of the receptor based on the sensor 500 or the change in the characteristic of the aerosol generator 200 (see Figures 57 to 60 ), changes in resonant frequency (see Figure 36 to Figure 45 ), changes in magnetism (see Figures 46 to 52 ), and equivalent resistance (see Figure 53 to Figure 56 ) to measure or estimate the temperature of the sensor or the aerosol generator 200.

[0753] Alternatively, the mobile communication terminal or controller 100 may be configured based on the estimated or measured temperature of the sensor or aerosol generator 200 and / or the sensor or display module (see Figure 61 to Figure 65 ) to control the performance of the display module 710. For example, the mobile communication terminal may estimate the second temperature information based on the equivalent resistance of the susceptor or the aerosol generator 200 or the change of the equivalent resistance, and control the performance of the display module based on the estimated second temperature information and the first temperature information measured for the display module 710.

[0754] Alternatively, the display module 710 may include a flexible display including a first area in contact with a first surface of the aerosol generator 200 (see Figures 66 to 78). When it is sensed that a cigarette stick is accommodated in the aerosol generator 200, the first area of ​​the flexible display can be deformed into a curved surface. In addition, as described above, in response to the first area becoming a curved surface, the mobile communication terminal or the controller 100 can calculate the equivalent resistance (or magnetic change or resonant frequency change) of the aerosol generator 200 or the receptor, and estimate the temperature of the receptor.

[0755] Optionally, the mobile communication terminal may further include a heat pipe which is internally evacuated and includes a fluid (see Figure 79 to Figure 83 ). One area of ​​the heat pipe may be connected to the first area of ​​the aerosol generator, and another area of ​​the heat pipe may be connected to the second area of ​​the mobile communication terminal. The controller 100 may predict the temperature change of the aerosol generator 200 by further considering the thermal conductivity of the heat pipe, and may control the power of the aerosol generator 200 or control the performance of the display module 710 based on the predicted temperature change.

[0756] Alternatively, the mobile communication terminal may include an antenna provided with a sheet formed of a conductor and a ground portion spaced apart from the sheet. The antenna may be coupled to the aerosol generator and provided on the body of the aerosol generator (see Figure 28 to Figure 35 ).

[0757] A method of estimating the temperature of the susceptor by estimating the equivalent resistance of the susceptor through the controller 100 will be described in detail below.

[0758] Fig.54 Schematic diagram of an aerosol generator based on the external induction heating method.

[0759] See also Fig.54 The aerosol generator 200 may include a DC / AC converter 6011 , an impedance matcher 6013 , and an inductor 6015 .

[0760] The aerosol generator may receive DC and / or DC power from a DC power supply 6019, and convert the DC into AC through a DC / AC converter 6011. Here, the DC power supply 6019 may be a power supply unit 300 included in a mobile communication terminal. AC may be applied to the inductor 6015 after impedance matching through an impedance matcher (or transformer) 6013. The inductor 6015 may generate an alternating magnetic field whose polarity varies according to the frequency of the AC when AC is applied. The alternating magnetic field may generate heat in a susceptor 6017 included in the cigarette stick. Here, the inductor 6015 may be in the form of a spirally wound cylindrical coil, but is not limited thereto. It may be composed of various types of coils capable of generating an alternating magnetic field.

[0761] The cigarette rod may include an aerosol generating substance and a susceptor 6017. The susceptor 6017 may include a conductor that may be inductively heated by the inductor 6015. Specifically, the susceptor 6017 may include a conductor from which heat is generated by an alternating magnetic field generated by the inductor 6015. For example, the conductor may include stainless steel, etc., from which heat is generated by an alternating magnetic field. The susceptor 6017 may have various shapes, such as rectangular, circular, and elliptical. The heat generated by the inductive heating of the susceptor 6017 is transferred to the aerosol generating substance included in the cigarette rod, and an aerosol may be generated from the material by the transferred heat.

[0762] As described above, the sensor can generate the first load information by measuring the voltage of the DC power supply and the DC applied to the DC / AC converter 6011 or the aerosol generator. For example, the sensor can sense the DC and DC voltage applied to the aerosol generator by being electrically connected to the DC power supply and / or the DC / AC converter 6011.

[0763] The controller may receive first load information from the sensor and calculate an equivalent resistance of the aerosol generator based on the first load information. The controller may control the DC / AC converter 6011 of the aerosol generator to control power applied to the aerosol generator based on the calculated equivalent resistance.

[0764] The equivalent resistance calculated by the controller based on the first load information will be described in more detail below.

[0765] Fig.55 is a graph showing the equivalent resistance of an aerosol generator housing a smoke rod including a susceptor.

[0766] refer to Fig.55 , the equivalent resistance R of the aerosol generator T The first resistance R of the inductor may correspond to TL and the second resistor R of the sensor TS Here, reference Fig.55 The resistance of the described DC / AC converter may have a negligibly low resistance compared to the resistance of the susceptor and the inductor. Here, the second resistance R of the susceptor TS Can vary with temperature.

[0767] For example, the second resistor R TS The second resistance R of the susceptor may increase in response to an increase in the temperature of the susceptor, or TS can decrease in response to a decrease in the temperature of the susceptor. TS The second resistor R of the sensor is included because it changes according to the temperature. TS The equivalent resistance R TIt can also vary with temperature. In this case, the equivalent resistance R T The temperature of the corresponding susceptor can have a single value. The equivalent resistance R of the susceptor T and temperature may have a monotonic function relationship with respect to each other. That is, due to the equivalent resistance R of the sensor T It has a one-to-one correspondence with temperature and can be obtained by calculating the equivalent resistance R of the sensor. T The corresponding relationship between the temperature is pre-analyzed and the equivalent resistance R for the sensor is pre-configured T In this case, the controller can be based on the predetermined equivalent resistance R of the sensor. T The corresponding relationship between the resistance and the temperature is used to estimate the temperature of the sensor corresponding to the calculated equivalent resistance.

[0768] The following will describe in detail the temperature and equivalent resistance R based on the above sensor. T The corresponding relationship between the method of controlling the power of the aerosol generator through the controller.

[0769] Fig.56 is a flow chart illustrating a method of controlling power to an aerosol generator based on an equivalent resistance calculated by a controller.

[0770] refer to Fig.56 , the controller may sense or monitor whether a cigarette stick is accommodated in the aerosol generator (S6501). For example, the controller may sense whether a cigarette stick is accommodated in the aerosol generator based on an optical sensor, a pressure sensor, etc. included in the aerosol generator.

[0771] When the cigarette stick is accommodated in the aerosol generator, the controller may start supplying power to the aerosol generator and obtain first load information from the sensor (S6503). Here, the first load information may include information about the voltage applied to the aerosol generator and the current applied to the aerosol generator as described above. As described above, the voltage and / or current included in the first load information may be a direct current (DC) voltage and / or a DC current.

[0772] The controller may calculate the equivalent resistance of the aerosol generator based on the first load information (S6505). For example, the controller may calculate the equivalent resistance of the aerosol generator based on the relationship between the voltage and the current included in the first load information according to Ohm's law. For example, the controller may calculate the equivalent resistance based on the value obtained by dividing the voltage by the current. As described above, the equivalent resistance may increase or decrease as the temperature of the receptor changes. For example, when the temperature of the receptor increases, the equivalent resistance may increase. When the temperature of the receptor decreases, the equivalent resistance may decrease. The controller may calculate the equivalent resistance based on the rate of change of the voltage.

[0773] In addition, the controller may periodically or irregularly acquire the first load information from the sensor, and calculate the change value of the equivalent resistance based on the first load information acquired periodically or irregularly. In this case, the controller may estimate whether the temperature of the receptor has increased or decreased based on the change value of the equivalent resistance. For example, if the change value of the equivalent resistance is negative, the controller may estimate that the temperature of the receptor has decreased. If the change value of the equivalent resistance is positive, the controller may estimate that the temperature of the receptor has decreased.

[0774] The controller may control the power or amount of power applied to the aerosol generator based on the equivalent resistance calculated according to the first load information (S6507). Specifically, the controller may estimate the temperature of the susceptor corresponding to the calculated equivalent resistance based on the correspondence between the predetermined equivalent resistance and the temperature of the susceptor as described above (e.g., a preconfigured lookup table). In this case, the controller may determine whether the estimated temperature of the susceptor reaches a first threshold temperature. When the estimated temperature of the susceptor reaches or exceeds the first threshold temperature, the controller may stop applying power to the aerosol generator. Alternatively, when the estimated temperature of the susceptor reaches or exceeds the first threshold temperature, the controller may apply a preset minimum amount of power to the aerosol generator.

[0775] Subsequently, the controller may continuously (or periodically) calculate the equivalent resistance based on the first load information, and may increase the amount of power applied to the aerosol generator (or restore power application) based on the change value of the equivalent resistance, or reduce the amount of power applied to the aerosol generator. Thus, the controller may maintain the temperature of the susceptor within a certain range starting from the first threshold temperature. Alternatively, the controller may calculate a temperature change value, which is the difference between the temperature of the susceptor corresponding to the first equivalent resistance calculated at the first time based on the first load information obtained regularly or irregularly and the temperature of the susceptor corresponding to the second equivalent resistance calculated at the second time (the time immediately after the first time). In this case, the controller may increase or decrease the amount of power applied to the aerosol generator based on the temperature change value.

[0776] For example, the controller can control the amount of power applied to the aerosol generator by adjusting the cycle (switching cycle) of a DC / AC converter included in the aerosol generator. For example, if the change value of the equivalent resistance is negative, the controller can increase the power applied to the aerosol generator by reducing the cycle of the DC / AC converter (increasing the alternating current (AC) frequency). If the change value of the equivalent resistance is positive, the power applied to the aerosol generator can be reduced by increasing the cycle of the DC / AC converter (reducing the AC frequency).

[0777] In addition, the controller may perform control operations related to the aerosol generator based on the equivalent resistance. Specifically, the controller may deduct (or count) the count value of the counter related to the aerosol generator based on the change value of the equivalent resistance. Here, the count value may be set to a default value of the maximum number of times (or the maximum number of puffs) that the aerosol generator can generate aerosol after receiving the cigarette stick. For example, when the change value of the equivalent resistance is greater than or equal to the first threshold change value, the controller may deduct the count value of the counter by 1. In addition, the first threshold change value may be a preset value based on the reduction in the equivalent resistance of the aerosol generator (or the reduction in the temperature of the receptor), which is a decrease in response to the inhalation of aerosol by a user of the mobile communication terminal or the aerosol generator due to the inflow of external air. For example, when the temperature of the receptor decreases by an average of the first temperature in response to the introduction of external air, the first threshold change value may be preset to the change in the equivalent resistance corresponding to the first temperature reduction, or to a value corresponding to the first temperature.

[0778] The controller may output the inverted count value through the display module. In addition, when the count value of the counter becomes 0, the controller may stop supplying power to the aerosol generator and initialize or reset the count value of the counter to an initial value.

[0779] Alternatively, the controller may obtain first temperature information about the display module from the sensor, and determine the increase rate and / or decrease rate of the power applied to the aerosol generator based on the first temperature information. For example, when the first temperature information is higher than or equal to a predetermined threshold temperature, the increase rate of the power amount may be preset to be lower than the increase rate of the power amount when the first temperature information is lower than the predetermined threshold temperature. Alternatively, when the first temperature information is higher than or equal to a predetermined threshold temperature, the decrease rate of the power amount may be preset to be higher than the decrease rate of the power amount when the first temperature information is lower than the predetermined threshold temperature. In this case, when the first temperature information is higher than or equal to the predetermined threshold temperature, the controller may increase the power amount at a slower speed or decrease the power amount at a faster rate to delay the display module temperature increase value to the maximum allowable temperature as much as possible, as described above. Here, the predetermined threshold temperature may be set to a temperature lower than the maximum allowable temperature, but at the predetermined threshold temperature, the first temperature information (or the temperature of the display module) may reach the maximum allowable temperature due to the temperature of the receptor within a predetermined first time interval. For example, the first time interval may be determined based on an average operation time from when the cigarette rod is received into the aerosol generator until aerosol generation is terminated, or based on a preset duration.

[0780] Alternatively, when the smoke stick is accommodated in the aerosol generator, the controller may limit the performance of the mobile communication terminal including the aerosol generator. For example, when the smoke stick is accommodated in the aerosol generator, the controller may switch the mobile communication terminal to standby mode (for example, by turning off the display of the display module to enter a terminal mode with minimum standby power), thereby minimizing the power consumption of the internal components of the mobile communication terminal. In this case, the internal equivalent resistance of the mobile communication terminal (the internal equivalent resistance does not include the equivalent resistance of the aerosol generator) may remain unchanged. Therefore, the controller may sense the change in the equivalent resistance of the receptor according to the temperature change of the receptor based on the equivalent resistance of the mobile communication terminal, and may estimate the temperature of the receptor based on the sensed change.

[0781] Another embodiment will be described below, in which the temperature of a susceptor in an aerosol generator can be sensed and used to control a system of a mobile communication terminal.

[0782] Fig.57 is a block diagram showing a mobile communication terminal including an aerosol generator. In the following description, redundant descriptions of the above details will be omitted.

[0783] refer to Fig.57 , the mobile communication terminal may include a controller 100 , an aerosol generator 200 , a power supply unit 300 , a sensor 500 , and an output unit 700 .

[0784] As described above, the controller 100 may perform overall control operations related to the operation of the mobile communication terminal. In addition, the controller 100 may perform control operations related to the generation of aerosols by the aerosol generator 200. For example, the controller 100 may perform control operations such as controlling the power applied to the aerosol generator 200 and reversing (or counting) a counter associated with the aerosol generator 200. In addition, the controller may control the performance of the output unit 700, which includes a display module 710 configured to generate outputs associated with visual, auditory, or tactile scenes.

[0785] When the cigarette stick is accommodated, the aerosol generator 200 can generate aerosol by heating the cigarette stick as described above. Regarding heating the cigarette stick, the aerosol generator 200 may include an external induction heater and an internally inserted induction heater, as described above with reference to Figures 4 to 27 In particular, the aerosol generator 200 can be based on the above reference Figures 4 to 17 An external induction heater performs operations related to aerosol generation, and the external induction heater heats the susceptor included in the cigarette rod inductively.

[0786] The power supply unit 300 may include a rechargeable battery capable of supplying DC power to the mobile communication terminal. The power supply unit 300 may be electrically connected to the aerosol generator 200 to supply DC power to the aerosol generator 200.

[0787] As described above, the sensor 500 may include one or more sensors configured to sense information within the mobile communication terminal, information about the surrounding environment of the mobile communication terminal, and user information. The sensor 500 may also include a characteristic change detection sensor 6801 configured to sense a magnetic change associated with a receptor included in the aerosol generator 200 or a cigarette stick. Alternatively, the characteristic change detection sensor 6801 may measure or estimate the power loss associated with the aerosol generator 200 based on the voltage and current associated with the aerosol generator 200, and sense the magnetic change associated with the receptor based on the estimated power loss.

[0788] Even if the susceptor of the cigarette stick accommodated in the aerosol generator 200 based on the external induction heater is physically separated from the aerosol generator 200, the controller 100 can indirectly measure or estimate the temperature of the susceptor using the characteristic change detection sensor 6801 in a specific manner. For example, as described below, the controller 100 can estimate the temperature of the susceptor by sensing the characteristic change (magnetic change and / or power loss change) related to the susceptor caused by the temperature change of the susceptor, and control the power applied to the aerosol generator 200 based on the estimated temperature of the susceptor.

[0789] Alternatively, the mobile communication terminal or the controller 100 may further consider the change of the resonance frequency (see Figure 36 to Figure 45 ), magnetic changes (see Figures 46 to 52 ) and equivalent resistance (see Figure 53 to Figure 56 ) to measure or estimate the temperature of the susceptor or aerosol generator 200. Alternatively, for example, the controller 100 may directly measure or estimate the temperature of the susceptor or aerosol generator 200 by a sensor (included in the sensor) configured to sense the temperature of the included display module 710. Alternatively, the controller 100 may measure or estimate the temperature of the susceptor or aerosol generator 200 by at least one of the following: a change in the resonant frequency calculated or sensed by the sensor 500 (see Figure 36 to Figure 45 ), magnetic changes (see Figures 46 to 52 ), equivalent resistance (see Figure 53 to Figure 56 ) and changes in the characteristics of the receptors (see Figures 57 to 60 ).

[0790] Alternatively, the mobile communication terminal or controller 100 may be based on the estimated or measured temperature of the sensor or aerosol generator 200 and / or the temperature of the display module (see Figure 61 to Figure 65 For example, the mobile communication terminal may estimate the second temperature information based on the magnetism or characteristic change of the receptor, and control the performance of the display module 710 based on the estimated second temperature information and the first temperature information measured for the display module.

[0791] Alternatively, the display module 710 may include a flexible display including a first area in contact with a first surface of the aerosol generator 200 (see Figures 66 to 78 ). When it is sensed that the cigarette stick is accommodated in the aerosol generator 200, the first area of ​​the flexible display can be deformed into a curved surface. In addition, as described above, in response to the first area becoming a curved surface, the mobile communication terminal or the controller 100 can sense a change in the characteristics or magnetism of the receptor (or a change in equivalent resistance, magnetism, or resonant frequency), and determine that the receptor has reached a specific temperature.

[0792] Alternatively, the mobile communication terminal may further include a heat pipe, the interior of the heat pipe is vacuum and contains a fluid (see Figure 79 to Figure 83 ). One area of ​​the heat pipe may be connected to the first area of ​​the aerosol generator, and another area of ​​the heat pipe may be connected to the second area of ​​the mobile communication terminal. The controller 100 may predict the temperature change of the aerosol generator 200 by further considering the thermal conductivity of the heat pipe, and may control the power of the aerosol generator 200 or control the performance of the display module 710 based on the predicted temperature change.

[0793] Alternatively, the mobile communication terminal may include an antenna and a grounding portion, the antenna being provided with a sheet formed of a conductor, the grounding portion being spaced apart from the sheet. The antenna may be coupled to the aerosol generator and provided on the body of the aerosol generator (see Figure 28 to Figure 35 ).

[0794] An embodiment of a method for sensing a change in a characteristic of a receptor (or a change in the magnetism of a receptor) will be described in detail below.

[0795] Fig.58 is a schematic diagram showing how an aerosol generator inductively heats a susceptor included in a tobacco rod.

[0796] refer to Fig.58 , the aerosol generator 200 may include a DC / AC converter 6711 , an impedance matcher 6713 , and an inductor 6715 .

[0797] The aerosol generator 200 may receive DC and / or DC power from a DC power supply 6719 and convert the DC to AC through a DC / AC converter 6711. Here, the DC power supply 6719 may be a power supply unit 300 included in a mobile communication terminal. AC may be applied to an inductor 6715 after impedance matching through an impedance matcher (or transformer) 6713. The inductor 6715 may generate an alternating magnetic field when an alternating current is applied, and the polarity of the alternating magnetic field changes according to the frequency of the alternating current. The alternating magnetic field may generate heat in a susceptor 6717 included in a cigarette stick. Here, the inductor 6715 may be in the form of a spirally wound cylindrical coil, but is not limited thereto. The inductor 6715 may be composed of various types of coils capable of generating an alternating magnetic field.

[0798] The susceptor 6717 may be close to the material capable of generating an aerosol and included in the cigarette stick. The susceptor 6717 is physically separated from the inductor 6715. The susceptor 6717 may be inductively heated by the alternating magnetic field generated by the inductor 6715. For example, the susceptor 6717 may include a conductor such as stainless steel, from which heat is generated by the alternating magnetic field generated by the inductor 6715. The susceptor 6717 may have various shapes such as rectangular, circular, and elliptical.

[0799] In addition, the susceptor 6717 may include a ferromagnetic material or a ferromagnetic material whose magnetism changes from ferromagnetism to paramagnetism when heated to a specific temperature (or Curie temperature). In this case, when the susceptor 6717 is heated to a specific temperature, the susceptor 6717 may lose its ferromagnetism and have paramagnetism. Here, the specific temperature may be an optimal temperature for the material suitable for generating aerosols to generate aerosols. In addition, when the susceptor 6717 is heated to a specific temperature, due to the change in the magnetism of the susceptor 6717, the power loss can be significantly reduced to below a predetermined level.

[0800] Fig.59 is a schematic diagram showing how the characteristic change sensor senses the characteristic change of a receptor.

[0801] refer to Fig.59 , the mobile communication terminal may include a characteristic change detection sensor 6801 and an aerosol generator 200. Here, the characteristic change detection sensor 6801 may be disposed at a position for sensing the magnetism of the receptor 6810, and may be included in the aerosol generator 200 when necessary.

[0802] The aerosol generator 200 may include an inductor 6820. The aerosol generator 200 may accommodate a cigarette rod including a susceptor 6810. The inductor 6820 may include a coil wound on the outer surface of the accommodating space along the longitudinal direction of the aerosol generator 200. When alternating current is applied to the inductor 6831, the inductor 6831 may generate an alternating magnetic field to heat the susceptor 6810.

[0803] When the susceptor 6810 is heated above a certain temperature, the magnetism of the susceptor 6810 included in the cigarette rod may change from ferromagnetism to paramagnetism, or when the susceptor 6810 is cooled below a certain temperature, the magnetism of the susceptor 6810 included in the cigarette rod may change from paramagnetism to ferromagnetism. In addition, the susceptor 6810 may experience a sharp increase or decrease in power loss due to the change in magnetism. For example, when the susceptor 6810 is heated above a certain temperature and the magnetism changes from ferromagnetism to paramagnetism, the power loss of the susceptor 6810 may be significantly reduced. On the other hand, when the susceptor 6810 is cooled below a certain temperature and the magnetism changes from paramagnetism to ferromagnetism, the power loss of the susceptor 6810 may be significantly increased.

[0804] The characteristic change detection sensor 6801 may transmit the sensed magnetism change information of the receptor 6810 to the controller 100 based on the change of the magnetism of the receptor 6810. For example, when the magnetism of the receptor 6810 sensed at the first time is not sensed at the second time as the next sensing time (for example, because the receptor 6810 is heated to a certain temperature or more), the characteristic change detection sensor 6801 may transmit the first information about the magnetism change of the receptor 6810 to the controller 100. In this case, the controller 100 may determine that the magnetism of the receptor has changed from ferromagnetism to paramagnetism based on the first information. Alternatively, when the magnetism of the receptor 6810 that has not been sensed after the second time (for example, because the receptor 6810 is cooled to a certain temperature or less) is sensed again at a third time, the characteristic change detection sensor 6801 may transmit the second information about the magnetism change of the receptor to the controller 100. In this case, the controller 100 may determine that the magnetism of the receptor has changed from paramagnetism to ferromagnetism. The characteristic change detection sensor 6801 may be a geomagnetic field sensor included in the mobile communication terminal. Alternatively, the characteristic change detection sensor 6801 may provide only the first information between the first information and the second information to the controller 100 .

[0805] Alternatively, the characteristic change detection sensor 6801 may transmit information about whether the magnetism of the susceptor 6810 changes to the controller 100 based on the power loss measured for the susceptor 6810 or the aerosol generator 200. For example, when the power loss measured for the susceptor 6810 or the aerosol generator 200 decreases by more than a preset amplitude, the characteristic change detection sensor 6801 may transmit first information about the change in magnetism of the susceptor 6810 to the controller 100. Alternatively, when the power loss measured for the susceptor 6810 or the aerosol generator 200 increases to more than a preset amplitude, the characteristic change detection sensor 6801 may transmit second information about the change in magnetism of the susceptor 6810 to the controller 100.

[0806] Hereinafter, an embodiment will be described in detail in which the controller 100 estimates the temperature of the susceptor 6810 based on the first information and the second information of the characteristic change detection sensor 6801 and controls the power of the aerosol generator 200 based on the estimated temperature of the susceptor 6810.

[0807] Fig.60 is a diagram illustrating a method of controlling power to an aerosol generator by a controller based on an estimated temperature of a susceptor.

[0808] refer to Fig.60 , the controller may sense whether the cigarette stick is accommodated in the aerosol generator (S6901). When the controller senses that the cigarette stick is accommodated in the aerosol generator, the controller may start to apply power to the aerosol generator to inductively heat the susceptor.

[0809] Next, the controller may estimate the temperature of the receptor based on the information obtained from the characteristic change sensor (S6903). Specifically, when the magnetism of the receptor changes from ferromagnetism to paramagnetism, the controller may receive first information from the characteristic change sensor. In this case, the controller may estimate that the temperature of the receptor is a specific temperature (or Curie temperature) or higher than the specific temperature based on the first information. Alternatively, when the magnetism of the receptor changes from paramagnetism to ferromagnetism, the controller may receive second information from the characteristic change sensor. In this case, the controller may estimate that the temperature of the receptor is lower than the specific temperature (or Curie temperature) based on the second information.

[0810] Next, the controller may control the power supplied to the aerosol generator based on the estimated temperature of the receptor (S6905). Specifically, the controller may estimate that the temperature of the receptor has reached the first temperature or Curie temperature based on the first information. In this case, the controller may stop applying power to the aerosol generator (or reduce the amount of power applied). That is, the controller may cool the receptor by stopping the power supply to the aerosol generator. Alternatively, the controller may estimate that the temperature of the receptor is lower than the second temperature or Curie temperature based on the second information. In this case, the controller may resume applying power to the aerosol generator (or increase the amount of power) so that the receptor is heated to a specific temperature or above a specific temperature. In this way, the controller can keep the temperature of the receptor within a specific range of a specific temperature or Curie temperature.

[0811] Alternatively, the controller may control the power to the aerosol generator based on the first information received from the characteristic change sensor. In other words, the controller may receive only the first information between the first information and the second information from the characteristic change sensor. For example, the controller may estimate that the temperature of the receptor is higher than or equal to a specific temperature based on the first information, and stop supplying power to the aerosol generator. In this case, the controller may stop supplying power within a preset time, and resume supplying power to the aerosol generator after the preset time has passed. Here, the preset time may be set based on the temperature information of the display module in the mobile communication terminal. Conversely, for example, when the temperature of the display module is lower than the first threshold temperature, the preset time may be set to a time set as a default value. When the temperature of the display module is higher than the first threshold temperature, the preset time may be set or adjusted to a value less than the default value.

[0812] Alternatively, the controller may decrement the counter value of the counter associated with the aerosol generator based on sensing the magnetic change of the receptor. For example, when the controller receives the second information from the sensing characteristic change, the controller may decrement the counter value of the counter by 1. In addition, the controller may output the decremented counter value using the above-mentioned display module.

[0813] Fig.61 is a block diagram schematically illustrating an embodiment of a mobile communication terminal including an aerosol generator. In the following description, redundant description of the above details will be omitted.

[0814] refer to Fig.61 , the mobile communication terminal may include a controller 100 , an aerosol generator 200 , an output unit 700 , and a sensor 500 .

[0815] The output unit 700 may include a display module 710 and may be configured to generate an output related to vision, hearing, or touch. The sensor 500 may include an environment sensor capable of generating first temperature information by sensing the temperature of the display module 710.

[0816] The controller 100 may use the sensor 500 to obtain first temperature information including the sensed temperature of the display module 710. The controller 100 may control the performance of the display module 710 based on the first temperature information. Here, the performance of the display module 710 may be related to brightness, frame rate, resolution, etc.

[0817] For example, the controller 100 may reduce or enhance the performance of the display module 710 based on the first temperature information. Here, reducing the performance of the display module 710 may be reducing brightness, frame rate or resolution. Enhancing the performance of the display module 710 may be increasing brightness, frame rate or resolution. The controller 100 may prevent the temperature of the display module 710 from rising to the 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 may be 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 may be preset. For example, a lookup table mapping the control parameters corresponding to the first temperature information may be pre-stored in the mobile communication terminal, and the controller 100 may control the performance of the display module 710 using the control parameters of the performance corresponding to the first temperature information based on the lookup table.

[0818] Alternatively, the controller 100 may additionally consider the second temperature information measured for the aerosol generator 200 as temperature information for controlling the performance of the display module 710 based on whether a smoke stick is accommodated in the aerosol generator 200. For example, when a smoke stick is not accommodated in the aerosol generator 200, the controller 100 may control the performance of the display module 710 based on the first temperature information on the display module 710 from the sensor 500. On the other hand, when a smoke stick is accommodated in the aerosol generator 200, the performance of the display module 710 may be controlled by further considering the second temperature information on the aerosol generator 200 acquired from the sensor 500. Here, the second temperature information is temperature information on the aerosol generator 200, and may more specifically include the airflow passing temperature of the airflow introduced into and discharged from the aerosol generator 200.

[0819] Alternatively, the electrical connection for temperature sensing between the sensor 500 and the display module 710 and / or the aerosol generator 200 may be turned on / off under the control of the controller 100. For example, when the cigarette stick is not accommodated in the aerosol generator 200, the electrical connection for temperature sensing between the sensor 500 and the display module 710 may be turned off, and the electrical connection for temperature sensing between the sensor 500 and the aerosol generator 200 may be turned off. On the contrary, when the cigarette stick is accommodated in the aerosol generator 200, the electrical connection for temperature sensing between the sensor 500 and the aerosol generator 200 may be turned on.

[0820] Alternatively, the mobile communication terminal or controller 100 may measure or estimate the temperature of the susceptor or aerosol generator by further considering one of the following: a change in the resonant frequency (see Figure 36 to Figure 45 ), changes in magnetism (see Figures 46 to 52 ), equivalent resistance (see Figure 53 to Figure 56 ) and changes in receptor properties (see Figure 57 to Figure 60 ). For example, the controller 100 may measure or estimate the temperature of the susceptor or aerosol generator 200 based on at least one of the following calculated or sensed by the sensor 500: a change in the resonant frequency (see Figure 36 to Figure 45 ), changes in magnetism (see Figures 46 to 52 ), equivalent resistance (see Figure 53 to Figure 56 ) and changes in receptor properties (see Figures 57 to 60 ).

[0821] Alternatively, the display module 710 may include a flexible display including a first area that contacts a first surface of the aerosol generator 200 (see Figures 66 to 78 ). When it is sensed that a cigarette stick is accommodated in the aerosol generator 200, the first area of ​​the flexible display may be deformed into a curved surface. In addition, as described above, in response to the first area changing into a curved surface, the mobile communication terminal or the controller 100 may start measuring the second temperature information about the aerosol generator 200.

[0822] Alternatively, the mobile communication terminal may further include a heat pipe, the interior of the heat pipe is vacuum and contains a fluid (see Figure 79 to Figure 83 ). One area of ​​the heat pipe may be connected to the first area of ​​the aerosol generator, and another area of ​​the heat pipe may be connected to the second area of ​​the mobile communication terminal. The controller 100 may further consider predicting the temperature change of the aerosol generator 200 according to the thermal conductivity of the heat pipe, and may control the power to the aerosol generator 200 or control the performance of the display module 710 based on the predicted temperature change.

[0823] Alternatively, the mobile communication terminal may include an antenna provided with a sheet formed of a conductor and a ground portion spaced apart from the sheet. The antenna may be coupled to the aerosol generator and arranged on the body of the aerosol generator (see Figure 28 to Figure 35 ).

[0824] Hereinafter, a method of controlling the performance of the display module 710 based on the temperature information acquired by the controller 100 according to whether the cigarette rod is accommodated in the aerosol generator 200 will be described in detail.

[0825] Fig.62 and Fig.63 A method of controlling the performance of a display module by a controller based on whether a cigarette stick is accommodated in an aerosol generator is shown.

[0826] refer to Fig.62 , the controller may sense whether a cigarette stick is accommodated in the aerosol generator (S6101). Whether the cigarette stick is accommodated may be sensed based on a pressure sensor, an optical sensor, or the like included in the aerosol generator.

[0827] Based on the smoke stick not sensed by the aerosol generator, the controller may acquire first temperature information by controlling the sensor (S6103). Here, the first temperature information may include the temperature of the display module measured as described above.

[0828] The controller may control the performance of the display module based on the first temperature information (S6104). For example, based on the first temperature information including the first value, the controller may control the performance of the display module using the first performance corresponding to the first value (or the preset control parameter corresponding to the first performance). Based on the first temperature information including the second value, the controller may control the performance of the display module using the second performance corresponding to the second value (or the preset control parameter corresponding to the second performance). In this case, when the second value is greater 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 may be lower than the resolution and / or frame rate of the display module according to the first performance.

[0829] For example, refer to Fig.63(a), the controller may acquire first temperature information including a second value (TP2) at a first time, and may control the performance of the display module based on a second performance corresponding to the second value (TP2), so that the display module has a frame rate (1 / T1). At a second time later than the first time, the controller may acquire first temperature information including a first value (TP1) less than the second value (TP2), and may control the performance of the display module based on the first performance corresponding to the first value (TP1), so that the display module has a frame rate (1 / T2). In this case, since T2 is less than T1, the performance of the display module is improved.

[0830] Alternatively, refer to Fig.63 (b), the controller may acquire first temperature information including a second value (TP2) at a first time, and may control the performance of the display module according to a second performance corresponding to the second value (TP2), so that the display module has a first resolution. At a second time later than the first time, the controller may acquire first temperature information including a first value (TP1) less than the second value (TP2), and may control the performance of the display module according to the first performance corresponding to the first value (TP1), so that the display module has a second resolution. Here, the second resolution is higher than the first resolution. In addition, the controller may 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.

[0831] Based on sensing that the cigarette stick is accommodated in the aerosol generator, the controller may acquire the first temperature information and the second temperature information by controlling the sensor (S6105). As described above, the sensor may be configured to sense not only the temperature of the display module but also the temperature of the aerosol generator. The controller may control the sensor to acquire the second temperature information in response to sensing that the cigarette stick is accommodated in the aerosol generator. Alternatively, the controller may only acquire the second temperature information from the sensor.

[0832] Then, the controller may control the performance of the display module based on the first temperature information and the second temperature information (S6106).

[0833] Specifically, the controller may modify the first temperature information based on the second temperature information, and control the performance of the display module based on the modified first temperature information. For example, considering 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., the expected temperature increment associated with the first temperature information may be predetermined according to the temperature difference. For example, a second lookup table may be preconfigured, in which the expected temperature increment for the temperature difference is defined. The controller may modify the first temperature information to further reflect the expected temperature increment determined based on the second lookup table, and control the performance of the display module based on the modified first temperature information. Alternatively, the second lookup table may have a temperature increase rate predetermined according to the temperature difference, rather than the expected temperature increment.

[0834] In other words, when a cigarette stick is placed in the aerosol generator, the controller can control the performance of the display module based on the first temperature information that is corrected to reflect the expected temperature increment determined based on the temperature difference between the first temperature information and the second temperature information, rather than controlling the performance of the display module based on the current first temperature information about the display module.

[0835] For example, when the first temperature information includes a first value and the second temperature information includes a second value, the controller may calculate a first temperature difference, that is, the difference between the first value and the second value, and determine an expected temperature increment corresponding to the first temperature difference (based on a second lookup table). The controller may correct the first value to a third value by reflecting the expected temperature increment of the first value, and may control the performance of the display module based on the third value (or the temperature corresponding to the third value). For example, when a cigarette rod is not accommodated in the aerosol generator, the controller may control the performance of the display module based on a first performance corresponding to the first value. However, when a cigarette rod is accommodated in the aerosol generator, the controller may control the performance of the display module based on a third performance corresponding to the third value, rather than the first value. In this case, the first value may be corrected to a larger third value, and the third performance corresponding to the third value may be set to a lower resolution and / or frame rate than the first performance corresponding to the first value. In this case, the controller may control the performance of the display module in advance, taking into account the expected temperature increment of the display module caused by the temperature of the aerosol generator, thereby minimizing the damage to the display module caused by the high temperature of the aerosol generator.

[0836] In addition, the controller may perform operations related to the aerosol generator and the display module based on the second temperature information. The relevant details will be described below.

[0837] Fig.64 and Fig.65 An embodiment of a method of performing, by a controller, operations related to an aerosol generator based on second temperature information is shown.

[0838] The controller may control operations related to the aerosol generator based on the second temperature information. Here, the operations may include controlling an operating state of the aerosol generator and controlling power applied to the aerosol generator, and decrementing a counter value of a counter related to the aerosol generator.

[0839] First, refer to Fig.64 , the controller may deduct the counter value of the counter associated with the aerosol generator based on the second temperature information. Here, the counter may be preset to a counter value corresponding to the maximum number of aerosol generation provided by the aerosol generator (or the maximum number of puffs of the electronic cigarette).

[0840] Specifically, the controller may sense whether the cigarette stick is accommodated in the aerosol generator (S6201). When the cigarette stick is accommodated, the controller may obtain second temperature information from the sensor. Here, the second temperature information may be the airflow passing temperature in the aerosol generator as described above.

[0841] The controller may reverse the counter associated with the aerosol generator based on the second temperature information (S6203). Specifically, when the cigarette stick is accommodated in the aerosol generator, the controller may periodically obtain the second temperature information about the aerosol generator, and may sense whether the temperature of the aerosol generator is reduced by the first threshold temperature or more based on the periodically obtained second temperature information. When it is sensed that the temperature of the aerosol generator is reduced by the first threshold temperature or more based on the second temperature information, the controller may reverse the counter value by 1. Alternatively, the controller may output the reversed counter value through the display module to provide information about the remaining number of aerosol generation (or the remaining number of puffs) to the user of the aerosol generator or the user of the mobile communication terminal.

[0842] When the counter value of the counter becomes 0, the controller may reset or initialize the counter value of the counter (ie, set the counter to the maximum number of times of generating aerosol) (S6205).

[0843] Additionally, the controller may control the amount of power applied to the aerosol generator based on the second temperature information.

[0844] refer to Fig.65 , the controller may apply power to the aerosol generator in response to sensing that the cigarette stick is accommodated in the aerosol generator (S6301).

[0845] The controller may acquire second temperature information about the aerosol generator by controlling the above-mentioned sensor, and may control the amount of power applied to the aerosol generator based on the second temperature information (S6303).

[0846] For example, when a cigarette stick is accommodated in the aerosol generator, the controller may apply power to the aerosol generator so that the second temperature information reaches the second threshold temperature. Thereafter, when a temperature drop of the aerosol generator is sensed based on the periodically acquired second information, the controller may increase the amount of power applied to the aerosol generator. Alternatively, when an increase in the temperature of the aerosol generator is sensed based on the periodically acquired second information, the second controller may reduce the amount of power applied to the aerosol generator.

[0847] Alternatively, the controller may control the amount of power applied to the aerosol generator by further considering the first temperature information. Specifically, the controller may increase or decrease the amount of power applied to the aerosol generator based on the second temperature information, and may determine the rate of increase and rate of decrease of the amount of power based on the first temperature information. For example, the rate of increase of power when the first temperature information is higher than or equal to a predetermined threshold temperature may be preset to be lower than the rate of increase of power when the first temperature information is lower than a predetermined threshold temperature. Alternatively, the rate of decrease of power when the first temperature information is higher than or equal to a predetermined threshold temperature may be preset to be higher than the rate of decrease of power when the first temperature information is lower than a predetermined threshold temperature. In this case, when the first temperature information is higher than or equal to a predetermined threshold temperature, the controller may increase the amount of power more slowly or decrease the amount of power more quickly than when the first temperature information is lower than a predetermined threshold temperature, thereby delaying the temperature increase of the display module to the maximum allowable temperature as much as possible as described above. Here, the predetermined threshold temperature may be set to a temperature lower than the maximum allowable temperature, but at this temperature, due to the temperature of the receptor, the first temperature information (or the temperature of the display module) is likely to reach the maximum allowable temperature within a predetermined first time interval. For example, the first time interval may be determined based on an average operation time from the time the smoke rod is received in the aerosol generator to the time the generation of aerosol is terminated, or may be determined based on a preset duration.

[0848] Alternatively, when the first temperature information is higher than or equal to a predetermined threshold temperature, the controller may adjust the second threshold temperature based on the first temperature information. For example, when the first temperature information is lower than the predetermined threshold temperature, the controller increases the temperature of the aerosol generator to the second threshold temperature. However, when the first temperature information is higher than or equal to the predetermined threshold temperature, the controller may increase the temperature of the aerosol generator only to a third threshold temperature lower than the second threshold temperature. For example, based on the first temperature information acquired when the placement of the cigarette stick is sensed, it may be determined whether to adjust the second threshold temperature based on the first temperature information.

[0849] Next, the controller may determine whether at least one of the preset conditions is met (S6305). Here, the preset conditions may include: a condition that the counter value is 0, a condition that a preset time has passed after the cigarette stick is placed in the aerosol generator, a condition that the cigarette stick is removed from the aerosol generator, or a condition that the first temperature information is higher than or equal to a specific threshold temperature. Here, the specific threshold temperature may be predetermined to be lower than the maximum allowable temperature and higher than a predetermined threshold temperature. When any of the preset conditions is not met, the controller may continue to control the power to the aerosol generator based on the second temperature information.

[0850] When at least one preset condition is met, the controller may stop applying power to the aerosol generator (S6307). In this operation, the controller may control the sensor to block the electrical connection for measuring the second temperature information about the aerosol generator. Alternatively, as described above, when at least one preset condition is met, the controller may reset the counter value of the counter.

[0851] Fig.66 1 is a front view of a mobile communication terminal without a cigarette stick according to an embodiment of the present disclosure. In the following description, redundant descriptions of the above details will be omitted.

[0852] The mobile communication terminal may include an aerosol generator 7200 and a flexible display 7711 including a first area 7712 in contact with a first surface of the aerosol generator 7200 .

[0853] The figure shows a front view of the mobile communication terminal, in which no smoke stick (not shown) is accommodated in the aerosol generator 7200. That is, since the smoke stick is not accommodated in the aerosol generator 7200, the first area 7712 of the flexible display 7711 remains flat.

[0854] In one embodiment, at least one area of ​​the flexible display 7711 of the present disclosure may be converted into a flat surface or a curved surface based on whether the cigarette rod is accommodated in the aerosol generator 7200 .

[0855] To this end, the flexible display 7711 may include a plurality of layers so that at least one region is converted into a flat surface or a curved surface. Relevant details will be described below with reference to the accompanying drawings.

[0856] Fig.67 1 is a front view of a mobile communication terminal containing a cigarette stick according to an embodiment of the present disclosure. In the following description, redundant description of the above details will be omitted.

[0857] The mobile communication terminal may include an aerosol generator 7200 and a flexible display 7711, wherein the flexible display 7711 includes an area 7712 in contact with a first surface of the aerosol generator 7200. Here, the aerosol generator 7200 may be formed to have a first length h. Here, the first length h may be determined based on the length of the cigarette rod 7100.

[0858] This embodiment shows a front view of a mobile communication terminal, in which a smoke stick 7100 is accommodated in an aerosol generator 7200. Here, the smoke stick 7100 is only an example, and may include any aerosol generating article capable of generating aerosol.

[0859] Specifically, since the cigarette stick 7100 is accommodated in the aerosol generator 7200, at least a portion of an area of ​​the flexible display 7711 is converted into a curved surface. That is, unlike a conventional curved display that remains flat or curved, the first area 7712 of the flexible display 7711 can be converted into a curved surface or plane with various curvatures. In this case, the curvature of the first area 7712 forming the curved surface is set so as not to cause physical damage to the flexible display 7711.

[0860] In addition, since the length of the aerosol generator 7200 is the first length h, the flexible display 7711 can form a bent portion of the first area 7712 of the flexible display 7711, whose length is only the same as the first length h.

[0861] Hereinafter, various elements necessary for converting the first area 7712 of the flexible display 7711 into a curved surface will be described in detail.

[0862] Fig.68 1 is a top view of a mobile communication terminal without a cigarette stick according to an embodiment of the present disclosure. In the following description, redundant descriptions of the above details will be omitted.

[0863] Here, the first area 7712, the second area 7713, and the third area 7714 may contact the support member on the A side, and may contact the panel for displaying an image on the A' side. The A side represents the rear surface of the mobile communication terminal, and the A' direction represents the front surface of the mobile communication terminal. The above situation is also applicable to the subsequent drawings.

[0864] In one embodiment, when the tobacco rod is not housed in the aerosol generator 7200 , the first surface 7201 of the aerosol generator 7200 may remain flat.

[0865] To this end, the first surface 7201 (dashed line) of the aerosol generator 7200 can be made of a ductile material (e.g., soft plastic or polymer) or a flexible material. In this case, the first surface 7201 and the surfaces of the aerosol generator 7200 other than the first surface 7201 (dashed line) can be made of different materials. Therefore, when the cigarette stick is inserted, the surfaces other than the first surface 7201 can maintain a fixed shape, and the first surface 7201 can be changed from a flat surface to a curved surface. Below, an embodiment of converting the first surface 7201 of the aerosol generator 7200 into a curved surface will be described in detail.

[0866] Likewise, the first area 7712 (dashed line), the second area 7713 and the third area 7714 of the flexible display 7711 may remain flat because no cigarette stick is accommodated therein.

[0867] The mobile communication terminal of this embodiment may include an aerosol generator 7200 and a flexible display 7711 , and the flexible display 7711 includes a first area 7712 in contact with the first surface 7201 of the aerosol generator 7200 .

[0868] The aerosol generator 7200 may accommodate a cigarette stick (not shown) that generates an aerosol. In one embodiment, the controller of the mobile communication terminal may sense that the cigarette stick is accommodated in the aerosol generator 7200. Since the cigarette stick is accommodated in the aerosol generator 7200, the first area 7712 may be converted into a curved surface. In one embodiment, the first area 7712 of the flexible display 7711 may be converted into a curved surface due to the pressure of accommodating the cigarette stick. The relevant details will be described later.

[0869] 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 generator 7200 may remain flat.

[0870] Hereinafter, a detailed description will be provided of the flexible display 7711 composed of a plurality of layers such that as the cigarette rod is accommodated in the aerosol generator 7200, at least a portion of the first region 7712 in contact with the first surface 7201 is converted into a curved surface.

[0871] Fig.69 1 is a top view of a mobile communication terminal without a cigarette stick according to an embodiment of the present disclosure. In the following description, redundant descriptions of the above details will be omitted.

[0872] In one embodiment, the aerosol generator 7200 may include a first hinge 7202, a second hinge 7203, a first portion 7204, a second portion 7205, and a third portion 7206. The first hinge 7202 and the second hinge 7203 may be symmetrically formed to correspond to each other in the aerosol generator 7200. In addition, the first portion 7204 may correspond to a component portion disposed on a surface of the aerosol generator 7200 in contact with a support member of a mobile communication terminal, and the second portion 7205 and the third portion 7206 may correspond to a component portion disposed on a surface of the aerosol generator 7200 in contact with a flexible display 7711 of a mobile communication terminal.

[0873] The first hinge 7202 may be formed in a structure connecting the first portion 7204 and the second portion 7205 of the aerosol generator 7200 , and the second hinge 7203 may be formed in a structure connecting the first portion 7204 and the third portion 7206 of the aerosol generator 7200 .

[0874] In one embodiment, the first hinge 7202 can allow the second part 7205 to be folded and unfolded, and the second hinge 7203 can allow the third part 7206 to be folded and unfolded. To this end, the first hinge 7202 and the second hinge 7203 can be fixed to the first part 7204. Fig.70 The second portion 7205 and the third portion 7206 are shown in a folded position.

[0875] Fig.70 1 is a top view of a mobile communication terminal containing a cigarette stick according to an embodiment of the present disclosure. In the following description, redundant description of the above details will be omitted.

[0876] exist Fig.70 , when a cigarette stick (not shown) is inserted, the second portion 7205 and the third portion 7206 respectively connected to the first hinge 7202 and the second hinge 7203 of the aerosol generator 7200 can be deformed into an unfolded shape. At this time, the first portion 7204 can remain fixed because the first portion 7204 is the portion of the aerosol generator 7200 that contacts the support member (i.e., the rear) of the mobile communication terminal.

[0877] When the user inserts the cigarette stick into the aerosol generator 7200, the second part 7205 connected to the first hinge 7202 and the third part 7206 connected to the second hinge 7203 can be unfolded. In another embodiment, the second part 7205 connected to the first hinge part 7202 and the third part 7206 connected to the second hinge part 7203 can be unfolded by the control of the mobile communication terminal according to the figure described below.

[0878] To this end, the first part 7204, the second part 7205, and the third part 7206 of the aerosol generator 7200 may be formed of different materials. For example, the first part 7204, the second part 7205, and the third part 7206 of the aerosol generator 7200 may be made of plastic, metal, or ceramic.

[0879] Therefore, by unfolding the second portion 7205 connected to the first hinge 7202 and the third portion 7206 connected to the second hinge 7203, the aerosol generator 7200 can provide a space in which the cigarette rod can be accommodated.

[0880] That is, the angle at which the second portion 7205 is unfolded around the first hinge 7202 and the angle at which the third portion 7206 is unfolded around the second hinge 7203 may correspond to an angle for accommodating the cigarette rod.

[0881] In addition, as the second portion 7205 and the third portion 7206 of the aerosol generator 7200 are unfolded, the first region 7712 of the flexible display 7711 is unfolded toward the front of the mobile communication terminal. For details, reference will be made to other drawings.

[0882] Fig.71 1 is a view showing an embodiment of the operation of the mobile communication terminal in the cigarette stick accommodation mode according to one embodiment of the present disclosure. In the following description, redundant description of the above details will be omitted.

[0883] The mobile communication terminal may output various applications on the flexible display 7711. In one embodiment, the mobile communication terminal may display an application icon 7715 related to the cigarette stick storage mode.

[0884] Here, the cigarette stick accommodation mode corresponds to a mode in which a user uses the mobile communication terminal as an electronic cigarette by generating aerosol using the aerosol generator 7200 included in the mobile communication terminal.

[0885] To this end, the mobile communication terminal may output an application icon 7715 for providing the cigarette stick accommodation mode. In one embodiment, the mobile communication terminal may receive a control signal 7716 for selecting an application icon 7715 associated with the cigarette stick accommodation mode. For example, the control signal 7716 corresponds to a control signal generated when a user touches the application icon 7715 output on the flexible display 7711 of the mobile communication terminal.

[0886] In response to receiving a control signal for selecting an application icon 7715 associated with the cigarette stick accommodation mode, the mobile communication terminal may deform the aerosol generator 7200 into a shape that may accommodate the cigarette stick.

[0887] In this case, the above-described figures can be referred to to show how to transform the aerosol generator 7200 into a shape that can accommodate a cigarette stick. When the aerosol generator 7200 is transformed into a shape that can accommodate the cigarette stick, the first area 7712 of the flexible display 7711 is bent or curved. For details, it will be described below with reference to the figures.

[0888] Fig.72 is a view showing a first area of ​​a flexible display of a mobile communication terminal according to one embodiment of the present disclosure. In the following description, redundant description of the above details will be omitted.

[0889] The flexible display 7711 of this embodiment may include a cover window 7811, a polarizing panel 7812, a touch panel 7813, a flexible display panel 7814 for displaying an image, and a base film 7815 disposed outside the flexible display panel 7814. For ease of explanation, the first region 7712 of the flexible display 7711 that can be deformed into a plane and a curved surface will be described by way of example. However, it should be appreciated that the second region (not shown) and the third region (not shown) of the flexible display 7711 may include the same components. The second region and the third region that remain flat may form a shape different from the multiple layers included in the first region 7712 that can be deformed into a flat and curved surface or have a different structure.

[0890] Hereinafter, each layer in the first region 7712 of the flexible display 7711 according to one embodiment will be described.

[0891] The flexible display 7711 may be made of a plurality of stacked layers. Each of the plurality of layers may be included in the first region 7712, the second region, and the third region.

[0892] More specifically, the cover window 7811 may be disposed on the front side (on the A' side) of the flexible display 7711. The cover window 7811 may protect the flexible display 7711 from external impacts. The cover window 7811 may include a material having physical flexibility. In addition, the cover window 7811 may include a transparent material to provide high light transmittance.

[0893] In one embodiment, the cover window 7811 included in the first area 7712 of the flexible display 7711 and the cover window 7811 included in the second area or the third area may be made of different materials. In one embodiment, the cover window 7811 included in the second area or the third area may be made of a rigid material, while the cover window 7811 included in the first area 7712 may be made of a relatively soft material. To this end, the cover window 7811 included in the second area or the third area may include an additional window layer because the cover window 7811 included in the second area or the third area requires greater mechanical rigidity than the cover window 7811 included in the first area 7712.

[0894] In particular, since the second area or the third area is more exposed to the front of the mobile communication terminal, the cover window 7811 of the second area or the third area may include multiple sublayers to ensure mechanical reliability such as impact resistance. In one embodiment, the cover window 7811 may include a double cover window.

[0895] The cover window 7811 included in the first region 7712 may be thinner or include a smaller number of layers than the second region or the third region to ensure flexibility of the first region 7712 of the flexible display 7711 .

[0896] The polarizing panel 7812 may be bonded to the touch panel 7813. The polarizing panel 7812 may prevent external light reflection to ensure a black view of the flexible display 7711. For example, user visibility may be improved by blocking reflection of light incident through a cover window 7811 provided on the polarizing plate 7813.

[0897] In one embodiment, the polarizing panel 7812 may include a polyethylene terephthalate (PET) film, a triacetyl cellulose (TAC) film, a cyclic olefin polymer (COP) film, or a polyvinyl alcohol (PVA) film. Based on another embodiment, in order to ensure the flexibility of the flexible display 7711, the polarizing panel 7812 may be formed of a thin film, as opposed to a polarizing layer in a conventional display. In addition, the polarizing panel 7812 may be disposed between the touch panel 7813 and the cover window 7811.

[0898] The touch panel 7813 may be disposed between the polarizing panel 7812 and the flexible display panel 7814. In one embodiment, the touch panel 7813 may be formed to have a plurality of touch electrodes disposed thereon. The touch electrodes may be controlled by a touch sensor IC. For example, the touch electrodes may sense a touch input or hovering input at a specific location by measuring a change in a signal (e.g., voltage, light intensity, resistance, or charge) at a specific location on the flexible display 7711, and provide information (e.g., position, area, pressure, or time) related to the sensed touch input or hovering input to the controller of the mobile communication terminal. In one embodiment, at least a portion of the touch panel 7813 (e.g., a touch sensor IC) may be included as a display driver IC as part of a display, or as part of another component (e.g., a coprocessor) outside the display.

[0899] In one embodiment, the touch panel 7813 may be formed of a thin film. The thin film may have a touch electrode in a thin film form.

[0900] The flexible display panel 7814 may include a liquid crystal display (LCD) panel, a light emitting diode (LED) display panel, an organic light emitting diode (OLED) display panel, a micro-electromechanical system (MEMS) display panel, or an electronic paper display panel. For example, the flexible display panel 7814 may have an OLED structure. The OLED panel may have a structure in which an organic light emitting layer is disposed between a top substrate and a bottom substrate. The polarizing panel 7812 may be disposed on the top substrate to emit light from the top substrate. The flexible display 7711 may also include a touch panel 7813 as an input device.

[0901] The base film 7815 may be disposed on the rear surface of the flexible display panel 7814 to protect the flexible display panel 7814. In this case, the base film 7815 may be made of a flexible material such as PI.

[0902] In one embodiment, the base film 7815 may be made of a flexible material. A typical display may include a base substrate made of glass arranged below the display panel. The glass is not suitable for a display that is continuously bent or curved, such as the flexible display 7711 based on various embodiments. Therefore, the base film 7815 may include an embossed layer and / or a buffer layer. However, depending on the flexibility of the flexible display 7711, the embossed layer or the buffer layer may be omitted.

[0903] In one embodiment, the cover window 7811, the polarizing panel 7812, the touch panel 7813, the flexible display panel 7814, and the base film 7815 may be adhered to each other by an optically clear adhesive layer (OCA) (not shown).

[0904] In one embodiment, the flexible display 7711 may also include various optical panels or optical films.

[0905] The first area 7712 of the flexible display 7711 formed in this structure may be converted into a flat surface or a curved surface based on whether a cigarette rod (not shown) is accommodated in the aerosol generator.

[0906] Fig.73 is a view showing a first area of ​​a flexible display of a mobile communication terminal according to another embodiment of the present disclosure. In the following description, redundant description of the above details will be omitted.

[0907] The plurality of layers included in the first region 7712 of the flexible display 7711 appear to be bent because the smoke rod is accommodated in the aerosol generator.

[0908] Therefore, 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 area 7712 may be deformed based on the shape of the cigarette rod (not shown) in the aerosol generator.

[0909] More specifically, the curved portion formed by 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 area 7712 can be determined based on the shape of the cigarette stick. For example, when the shape of the cigarette stick is a perfect circle, each component module included in the first area 7712 can be deformed into a curved portion that can surround the circular cigarette stick. When the shape of the cigarette stick is an ellipse, each component module included in the first area 7712 can be deformed into a curved portion that can surround the elliptical cigarette stick. In this case, each component module included in the first area 7712 can form a curved portion to surround the cigarette stick, but maintain a minimum curvature to prevent damage to the component module.

[0910] Fig.74 is a view showing a flexible display of a mobile communication terminal according to one embodiment of the present disclosure. In the following description, redundant description of the above details will be omitted.

[0911] As described above, the flexible display 7711 may include a plurality of layers. In the flexible display 7711 , the flexible display panel 7814 may include a substrate 7911 , a pixel array portion 7912 formed on the substrate 7911 , and a thin film encapsulation (TFE) layer 7913 covering the pixel array portion 7912 .

[0912] The pixel array section 7912 is composed of a plurality of pixels, and each pixel may include an LED. Here, the LED may be an OLED. The plurality of LEDs may be electrically connected to a display drive circuit and emit light according to an electrical signal. The display drive circuit may include a driver IC, and the driver IC may transmit power or an image signal to the plurality of LEDs through a wire.

[0913] A TFE layer 7913 may be formed on the pixel array portion 7912 to encapsulate a plurality of LEDs. Since OLED devices are very susceptible to moisture and oxygen. The TFE layer 7913 is used to prevent water and oxygen from penetrating into the LED. The TFE layer 7913 may protect the plurality of LEDs from moisture or oxygen by forming a plurality of organic or inorganic layers. In this case, the TFE layer 7913 may have a structure in which a composite layer including an organic layer and an inorganic layer is alternately stacked. In addition, the TFE layer 7913 may also include a thin film evaporation film.

[0914] In one embodiment, the pixel array portion 7912 may include a sub-pixel. The sub-pixel may include an anode electrode formed on the substrate 7911, an organic material formed on the anode electrode and capable of representing R, G, and B colors, and a cathode electrode formed on the organic material. Here, the anode electrode may form a single layer, or include a plurality of anode electrodes electrically connected to the flexible display panel 7814.

[0915] The TFE layer 7913 may cover the cathode electrode. The cathode electrode may be electrically connected to the pixel. The cathode electrode may be configured in the form of a layer disposed above a plurality of pixels. The cathode electrode may be disposed on top of the pixel array portion 7912.

[0916] In one embodiment, the flexible display 7711 may include a first area 7712 , a second area 7713 , and a third area 7714 . Fig.74 The plurality of layers included in the second region 7713 and the third region 7714 of the flexible display 7711 are shown. That is, the structure, shape or form of the plurality of layers maintained flat included in the second region 7713 and the third region 7714 may be different from that in the first region 7712, and the first region 7712 may be deformed into a curved surface.

[0917] Unlike the first region 7712, the base film 7815 in the second region 7713 or the third region 7714 can be formed to be flat.

[0918] In addition, the touch panel 7813 in the second area 7713 or the third area 7714 includes a plurality of touch electrodes arranged on the substrate 7911 and a touch panel circuit electrically connected to control each touch electrode. Here, the touch panel circuit formed on the touch panel 7813 may include conductive wires 7914 and 7915 extending in the column direction and the row direction of the touch panel 7813. Here, the conductive wires may be formed as a conductive pattern printed on the substrate 7911.

[0919] The wires may include: a first wire 7914 in a column-type wire, and a second wire 7915 in a row-type wire. In addition, one of the first wire and the second wire may be connected to the receiving electrode, and the other may be connected to the transmitting electrode. The first wire and the second wire may be electrically connected.

[0920] Fig.75 is a view showing a flexible display of a mobile communication terminal according to one embodiment of the present disclosure. In the following description, redundant description of the above details will be omitted.

[0921] The figure shows a plurality of 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 configuration described above.

[0922] In the case where the TFE layer 7913 associated with the second region 7713 and the third region 7714 is provided to cover the pixel array portion 7912 included in the first region 7712, the TFE layer 7913 may be continuously bent or folded and may be cracked. If cracks occur in the TFE layer 7913, black spots may appear on the display panel 7814. In order to prevent the generation of cracks, the TFE layer 7913 included in the first region 7712 may be provided to independently package some LEDs.

[0923] More specifically, the packaging components of the TFE layer 7913 can be spaced apart from each other, and an adhesive having a high elastic modulus and a low elastic modulus can fill the gaps between the packaging components. For this purpose, the packaging component can package one or more capsules into a trapezoid. The packaging component can individually package one or more pixels to minimize the stress applied to the TFE layer 7913 and prevent cracks from being generated in the layer. That is, the packaging component can independently package the organic material and the cathode electrode. Therefore, the flexible display 7711 can be smoothly bent without damaging the TFE layer 7913.

[0924] Unlike the second region 7713 and the third region 7714, the base film 7815 of the first region 7712 may have a groove formed in a direction perpendicular to the extending direction of the base film 7815. Here, the groove formed in the base film 7815 may be formed perpendicular to the direction in which the flexible display 7711 is bent. Therefore, when the first region 7712 is bent or folded, damage to the base film 7815 may be prevented.

[0925] The touch panel 7813 in the first region 7712 may include a plurality of touch electrodes disposed on the substrate 7911 and a touch panel circuit electrically connected to control each touch electrode. Likewise, the touch panel circuit formed on the touch panel 7813 may include wires 7914 and 7915 extending in the column direction and the row direction of the touch panel 7813. However, the wires included in the first region 7712 may have a structure different from the wires 7914 and 7915 included in the second region 7713 or the third region 7714.

[0926] In one embodiment, the second conductive line 7915 included in the first region 7712 may form a zigzag conductive pattern. On the other hand, the first conductive line 7914 may form a straight line in the second region 7713 or the third region 7714.

[0927] Considering the bending direction of the first region 7712, when the first conductive line 7914 is bent perpendicular to the bending direction, less stress may be applied to the longitudinal direction of the first conductive line 7914. Therefore, the first conductive line 7914 is less likely to be damaged or short-circuited due to bending.

[0928] On the other hand, the second wire 7915 arranged parallel to the bending direction may generate a large stress in the longitudinal direction of the second wire 7915, and this stress may play a stress role on the wire formed on the substrate 7911, causing the second wire 7915 to short-circuit or be damaged. Therefore, the second wire 7915 can be formed with a zigzag pattern. Therefore, the stress in the bending direction acting on the second wire 7915 can be effectively distributed.

[0929] Fig.76 is a view showing a pressure sensor array part of a flexible display according to one embodiment of the present disclosure. In the following description, redundant description of the above details will be omitted.

[0930] In particular, a pressure sensor array part 7921 included in the second area 7713 or the third area 7714 of the flexible display 7711 according to one embodiment of the present disclosure will be described.

[0931] The pressure sensor array portion 7921 may include at least one pressure sensor 7922 disposed on the array portion and a wire for electrically connecting the pressure sensor 7922 .

[0932] In one embodiment, the pressure sensor array portion 7921 may be omitted in the second region 7713 or the third region 7714. This is because when a cigarette stick is inserted, the first region 7712 needs to sense pressure, while the second region 7713 or the third region 7714 does not need to sense pressure.

[0933] Fig.77 is a view showing a pressure sensor array part of a flexible display according to one embodiment of the present disclosure. In the following description, redundant description of the above details will be omitted.

[0934] In particular, a pressure sensor array portion 7921 included in a first region 7712 of a flexible display 7711 according to an embodiment of the present disclosure will be described.

[0935] The pressure sensor array portion 7921 included in the first region 7712 may include a plurality of grooves 7923 .

[0936] Here, a plurality of grooves 7923 may be formed between the pressure sensors 7922 and may extend in a direction perpendicular to the bending direction or in a plurality of parallel directions perpendicular to the bending direction. In particular, the grooves 7923 formed in a dire...
