[0021] The terms used in the embodiments are general terms that are currently widely used while considering the functions in the present invention, but these may change according to the intentions or precedents of those skilled in the art, the emergence of new technologies, etc. Also, in certain cases, there are terms arbitrarily selected by the applicant, and in such cases, the meaning thereof will be described in detail in the description part of the corresponding invention. Therefore, the terms used in the present invention are not simply names of terms, but must be defined based on the meaning of the terms and the overall content of the present invention.

[0022] When any part of the specification states that any component "includes", this does not exclude other components unless otherwise stated to the contrary, but means that other components are further included. Also, terms such as "~ part" and "~ module" described in the specification mean units that process at least one function or operation, and these may be implemented in hardware or software, or in a combination of hardware and software.

[0023] As used in this specification, when an expression such as "at least any one of" is in front of the arranged components, it modifies the entire components that are not each of the arranged components. For example, the expression "at least any one of a, b, and c" must be interpreted to include a, b, c, or a and b, a and c, b and c, or a and b and c.

[0024] In the following embodiments, an "aerosol-generating article" is an article that contains a medium, and means an article through which an aerosol passes and the medium is transferred. A typical example of an aerosol-generating article is a roll-up tobacco, but the scope of the present disclosure is not limited thereto.

[0025] In the following embodiments, "upstream" or "upstream direction" means the direction away from the user's (smoker's) mouth, and "downstream" or "downstream direction" means the direction approaching the user's mouth. The terms upstream and downstream are used to describe the relative positions of the elements constituting the aerosol-generating article.

[0026] In the following embodiments, "puff" means inhalation by the user, and inhalation means the situation of drawing in through the user's mouth or nose into the user's oral cavity, nasal cavity, or lungs.

[0027] In one embodiment, an aerosol-generating device is a device that electrically heats an aerosol-generating article housed in an internal space to generate an aerosol.

[0028] The aerosol-generating device includes a heater. In one embodiment, the heater may be an electrical resistance heater. For example, the heater may include an electrically conductive track, and when an electric current flows through the electrically conductive track, the heater is heated.

[0029] The heater may include a tubular heating element, a plate-type heating element, a needle-type heating element, or a rod-type heating element, and heats the inside or outside of the aerosol-generating article according to the shape of the heating element.

[0030] The aerosol generating article includes a tobacco rod and a filter rod. The tobacco rod may be manufactured as a sheet, as a strand, or as cut tobacco in which the tobacco sheet is finely cut. Also, the tobacco rod can be surrounded by a heat conductive material. For example, the heat conductive material may be a metal foil such as aluminum foil, but is not limited thereto.

[0031] The filter rod may be an acetyl cellulose filter. The filter rod may be composed of at least one or more segments. For example, the filter rod includes a first segment for cooling the aerosol and a second segment for filtering a predetermined component contained in the aerosol.

[0032] In other embodiments, the aerosol generating device may be a device that generates an aerosol using a cartridge that holds an aerosol generating substance.

[0033] The aerosol generating device includes a cartridge that holds an aerosol generating substance and a body that supports the cartridge. The cartridge can be detachably coupled to the body, but is not limited thereto. The cartridge may be integrally formed or assembled with the body and fixed so as not to be detached by the user. The cartridge may be mounted on the body with the aerosol generating substance accommodated therein. However, without being limited thereto, the aerosol generating substance may be injected into the cartridge while the cartridge is coupled to the body.

[0034] The cartridge may hold an aerosol generating substance in any one of various states such as a liquid state, a solid state, a gaseous state, and a gel state. The aerosol generating substance includes a liquid phase composition. For example, the liquid phase composition may be a liquid containing a tobacco-containing substance containing a volatile tobacco flavor component, or a liquid containing a non-tobacco substance.

[0035] The cartridge functions to convert the phase of the aerosol generating substance inside the cartridge into a gaseous phase by being actuated by an electrical signal, a wireless signal, etc. transmitted from the main body, thereby generating an aerosol. An aerosol means a gas in a state where vaporized particles generated from the aerosol generating substance and air are mixed.

[0036] In a further embodiment, the aerosol generating device can heat a liquid-phase composition to generate an aerosol, and the generated aerosol may pass through a rolled tobacco and be transmitted to the user. That is, the aerosol generated from the liquid-phase composition moves along the air flow path of the aerosol generating device, and the air flow path can be configured such that the aerosol passes through the rolled tobacco and is transmitted to the user.

[0037] In a further embodiment, the aerosol generating device is a device that generates an aerosol from an aerosol generating substance using an ultrasonic vibration method. Here, the ultrasonic vibration method means a method of generating an aerosol by atomizing the aerosol generating substance with ultrasonic vibrations generated by a vibrator.

[0038] The aerosol generating device includes a vibrator, and can generate vibrations with a short period through the vibrator to atomize the aerosol generating substance. The vibrations generated by the vibrator may be ultrasonic vibrations, and the frequency band of the ultrasonic vibrations may be in the frequency band of about 100 kHz to about 3.5 MHz, but is not limited thereto.

[0039] The aerosol generating device further includes 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 may be arranged to contact at least one region of the vibrator.

[0040] When a voltage (e.g., an alternating voltage) is applied to the vibrator, heat and / or ultrasonic vibrations are generated from the vibrator, and the heat and / or ultrasonic vibrations generated from the vibrator are transmitted to the aerosol product substance absorbed by the core. The aerosol product substance absorbed by the core can be converted into the gas phase by the heat and / or ultrasonic vibrations transmitted from the vibrator, and as a result, an aerosol can be generated.

[0041] For example, the heat generated from the vibrator can lower the viscosity of the aerosol product substance absorbed by the core, and the aerosol product substance with lowered viscosity due to the ultrasonic vibrations generated from the vibrator can be atomized to generate an aerosol, but it is not limited to this.

[0042] In a further embodiment, the aerosol generating device may be a device that generates an aerosol by heating an aerosol generating article accommodated in the aerosol generating device by an induction heating method.

[0043] The aerosol generating device includes a susceptor and a coil. In one embodiment, the coil applies a magnetic field to the susceptor. When power is supplied from the aerosol generating device to the coil, a magnetic field is formed inside the coil. In one embodiment, the susceptor is a magnetic body that generates heat by an external magnetic field. When the susceptor is located inside the coil and generates heat by the applied magnetic field, the aerosol generating article is heated. Also, optionally, the susceptor may be disposed within the aerosol generating article.

[0044] In a further embodiment, the aerosol generating device may further include a cradle.

[0045] The aerosol generating device can form a system together with a separate cradle. For example, the cradle may charge the battery of the aerosol generating device. Or, the heater may be heated in a state where the cradle and the aerosol generating device are coupled.

[0046] The following will be described in detail so that those with ordinary knowledge in the art can easily implement the implementation of the present disclosure with reference to the accompanying drawings. The present disclosure can be implemented in a form that can be embodied in the aerosol generating devices of various embodiments described above, or can be embodied in different forms and is not limited to the embodiments described herein.

[0047] The following will describe the embodiments of the present disclosure in detail with reference to the drawings.

[0048] FIG. 1 is a block diagram of an aerosol generating device 100 according to an embodiment.

[0049] The aerosol generating device 100 includes a control unit 110, a detection unit 120, an output unit 130, a battery 140, a heater 150, a user input unit 160, a memory 170, and a communication unit 180. However, the internal structure of the aerosol generating device 100 is not limited to that shown in FIG. 1. That is, those with ordinary knowledge in the technical field related to this embodiment will understand that, depending on the design of the aerosol generating device 100, some of the configurations shown in FIG. 1 may be omitted or new configurations may be added.

[0050] The detection unit 120 detects the state of the aerosol generating device 100 or the state around the aerosol generating device 100 and transmits the detected information to the control unit 110. Based on the detected information, the control unit 110 can control the aerosol generating device 100 so that various functions such as operation control of the heater 150, restriction of smoking, determination of the presence or absence of insertion of an aerosol generating article (for example, an aerosol generating article, a cartridge, etc.), and notification display are performed.

[0051] The detection unit 120 includes at least one of a temperature sensor 122, an insertion detection sensor 124, and a puff sensor 126, but is not limited thereto.

[0052] The temperature sensor 122 detects the temperature at which the heater 150 (or the aerosol generating substance) is heated. The aerosol generating device 100 may include a separate temperature sensor for detecting the temperature of the heater 150, or the heater 150 itself may serve as a temperature sensor. Alternatively, the temperature sensor 122 may be disposed around the battery 140 so as to monitor the temperature of the battery 140.

Since the function of the angle sensor can be intuitively inferred by those skilled in the art from its name, a specific description thereof is omitted.

[0056] The output unit 130 outputs information regarding the state of the aerosol generating device 100 and provides it to the user. The output unit 130 includes at least one of a display unit 132, a haptic unit 134, and an acoustic output unit 136, but is not limited thereto. When the display unit 132 and the touch pad form a layer structure and are configured as a touch screen, the display unit 132 may be used as an input device in addition to the output device.

[0057] The display unit 132 visually provides information about the aerosol generator 100 to the user. For example, the information about the aerosol generator 100 means various information such as the charging / discharging state of the battery 140 of the aerosol generator 100, the preheating state of the heater 150, the insertion / removal state of the aerosol article, or the state in which the use of the aerosol generator 100 is restricted (e.g., detection of abnormal articles), and the display unit 132 can output the information to the outside. The display unit 132 is, for example, a liquid crystal display panel (LCD), an organic light-emitting diode display panel (OLED), or the like. Also, the display unit 132 may be in the form of an LED light-emitting element.

[0058] The haptic unit 134 converts an electrical signal into a mechanical or electrical stimulus to tactually provide information about the aerosol generator 100 to the user. For example, the haptic unit 134 includes a motor, a piezoelectric element, or an electrical stimulation device.

[0059] The acoustic output unit 136 aurally provides information about the aerosol generator 100 to the user. For example, the acoustic output unit 136 can convert an electrical signal into an acoustic signal and output it to the outside.

[0060] The battery 140 supplies the power used for the operation of the aerosol generator 100. The battery 140 supplies power so that the heater 150 can be heated. Also, the battery 140 can supply the power necessary for the operation of other components provided in the aerosol generator 100 (e.g., the detection unit 120, the output unit 130, the user input unit 160, the memory 170, and the communication unit 180). The battery 140 may be a rechargeable battery or a disposable battery. For example, the battery 140 may be a lithium polymer (LiPoly) battery, but is not limited thereto.

[0061] The heater 150 is supplied with power from the battery 140 to heat the aerosol product substance. Although not shown in FIG. 1, the aerosol generating device 100 may further include a power conversion circuit (for example, a DC / DC converter) that converts the power of the battery 140 and supplies it to the heater 150. Further, when the aerosol generating device 100 generates aerosol by an induction heating method, the aerosol generating device 100 further includes a DC / AC converter that converts the DC power source of the battery 140 into an AC power source.

[0062] The control unit 110, the detection unit 120, the output unit 130, the user input unit 160, the memory 170, and the communication unit 180 can be supplied with power from the battery 140 and perform their functions. Although not shown in FIG. 1, it may further include a power conversion circuit, such as an LDO (low dropout) circuit or a voltage regulator circuit, that converts the power of the battery 140 and supplies it to each component.

[0063] In one embodiment, the heater 150 can be formed of any suitable electrically resistive material. For example, suitable electrically resistive materials include metals or metal alloys such as titanium, zirconium, tantalum, platinum, nickel, cobalt, chromium, hafnium, niobium, molybdenum, tungsten, tin, gallium, manganese, iron, copper, stainless steel, nichrome, etc., but are not limited thereto. Further, the heater 150 can be realized by a metal wire, a metal hot plate on which an electrically conductive track is arranged, a ceramic heating element, etc., but is not limited thereto.

[0064] In other embodiments, the heater 150 may be an induction heating type heater. For example, the heater 150 includes a susceptor that generates heat through a magnetic field applied by a coil and heats the aerosol product substance.

[0065] In one embodiment, the heater 150 includes a plurality of heaters. For example, the heater 150 includes a first heater for heating the aerosol generating article and a second heater for heating the liquid phase.

[0066] The user input unit 160 can receive information input by the user or output information to the user. For example, the user input unit 160 includes, but is not limited to, a key pad, a dome switch, a touch pad (capacitive touch method, piezoresistive method, infrared sensing method, surface acoustic wave conduction method, integral tension measurement method, piezoelectric effect method, etc.), a jog wheel, a jog switch, etc. Although not shown in FIG. 1, the aerosol generating device 100 further includes a connection interface such as a USB (universal serial bus) interface, and can be connected to other external devices via a connection interface such as a USB interface to transmit and receive information or charge the battery 140.

[0067] The memory 170 is hardware for storing various data processed within the aerosol generating device 100, and can store the data processed by the control unit 110 and the data to be processed. The memory 170 includes at least one type of storage medium such as a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (e.g., SD or XD memory, etc.), a RAM (random access memory), an SRAM (static random access memory), a ROM (read-only memory), an EEPROM (electrically erasable programmable read-only memory), a PROM (programmable read-only memory), a magnetic memory, a magnetic disk, and an optical disk. The memory 170 may store the operating time of the aerosol generating device 100, the maximum puff count, the current puff count, at least one temperature profile, and data regarding the user's smoking pattern, etc.

[0068] The communication unit 180 includes at least one component for communication with other electronic devices. For example, the communication unit 180 includes a short-range communication unit 182 and a wireless communication unit 184.

[0069] The short-range wireless communication unit 182 includes, but is not limited to, a Bluetooth (registered trademark) communication unit, a BLE (Bluetooth (registered trademark) Low Energy) communication unit, a Near Field Communication unit, a WLAN (Wi-Fi) communication unit, a Zigbee (registered trademark) communication unit, an infrared (IrDA, infrared Data Association) communication unit, a WFD (Wi-Fi Direct) communication unit, a UWB (ultra wideband) communication unit, an Ant+ communication unit, etc.

[0070] The wireless communication unit 184 includes, but is not limited to, a cellular network communication unit, an Internet communication unit, a computer network (e.g., LAN or WAN) communication unit, etc. The wireless communication unit 184 may use subscriber information (e.g., International Mobile Subscriber Identifier (IMSI)) to identify and authenticate the aerosol generator 100 within the communication network.

[0071] The control unit 110 can control the overall operation of the aerosol generator 100. In one embodiment, the control unit 110 includes at least one processor. The processor may be implemented as an array of multiple logic gates, or as a combination of a general-purpose microprocessor and a memory storing a program executable by the microprocessor. Also, those with ordinary knowledge in the technical field to which this embodiment belongs can understand that it can be implemented in further forms of hardware.

[0072] The control unit 110 can control the temperature of the heater 150 by controlling the supply of power from the battery 140 to the heater 150. For example, the control unit 110 can control the power supply by controlling the switching of a switching element between the battery 140 and the heater 150. In a different example, in response to a control command from the control unit 110, a direct heating circuit may control the power supply to the heater 150.

[0073] The control unit 110 analyzes the results detected by the detection unit 120 and controls the processes to be executed thereafter. For example, the control unit 110 can control the power supplied to the heater 150 so that the operation of the heater 150 is started or terminated based on the results detected by the detection unit 120. As another example, the control unit 110 can control the amount of power supplied to the heater 150 and the time during which the power is supplied so that the heater 150 can be heated to a predetermined temperature or maintain an appropriate temperature based on the results detected by the detection unit 120.

[0074] The control unit 110 controls the output unit 130 based on the results detected by the detection unit 120. For example, when the number of puffs counted via the puff sensor 126 reaches a preset number, the control unit 110 can notify the user that the aerosol generator 100 will immediately end via at least one of the display unit 132, the haptic unit 134, and the acoustic output unit 136.

[0075] In one embodiment, the control unit 110 can control the power supply time and / or the power supply amount to the heater 150 according to the state of the aerosol generating article detected by the detection unit 120. For example, when the aerosol generating article is in an over-wet state, the control unit 110 can control the power supply time to the induction coil and increase the preheating time compared to when the aerosol generating article is in a normal state.

[0076] One embodiment can also be realized in the form of a recording medium including computer-executable instructions such as program modules executed by a computer. A computer-readable medium may be any soluble medium accessible by a computer, including all volatile and non-volatile media, and all removable and non-removable media. Also, a computer-readable medium includes all computer storage media and communication media. Computer storage media includes all volatile and non-volatile, removable and non-removable media implemented by any method or technology for storing information such as computer-executable instructions, data structures, program modules, or other data. Communication media typically includes modulated data signals such as computer-executable instructions, data structures, program modules, or other data, or other transmission mechanisms, and includes any information transmission media.
