For example, the electrical resistive heater can include at least one electrically conductive track and can be heated by passing an electric current through the electrically conductive track. Here, the aerosol generating material can be heated by the heated electrical resistive heater.

[0031] The electrically conductive track may comprise an electrically resistive material. As an example, the electrically conductive track may be made of a metallic material. As another example, the electrically conductive track may be made of a ceramic material, carbon, a metal alloy, or a composite of a ceramic material and a metal.

[0033] The aerosol generating module 13 may include a heater using an induction heating method. For example, an induction heater may include an electric conductive coil, and an alternating magnetic field whose direction changes periodically may be generated by adjusting a current flowing through the electric conductive coil. Here, when an alternating magnetic field is applied to a magnetic material, energy loss due to eddy current loss and hysteresis loss may occur in the magnetic material, and the lost energy may be released as thermal energy to heat the aerosol generating material adjacent to the magnetic material. Here, the object that generates heat due to the magnetic field may be called a susceptor.

[0034] On the other hand, the aerosol generation module 13 can also generate an aerosol from an aerosol-generating substance by generating ultrasonic vibrations.

[0035] The aerosol generating module 13 may be referred to as a cartomizer, an atomizer, a vaporizer, or the like.

[0036] The memory 14 can store programs for each signal processing and control within the control unit 17, and can store data processed by the control unit 17 and data to be processed.

[0037] For example, memory 14 can store application programs designed to perform various tasks that can be processed by control unit 17, and can selectively provide some of the stored application programs upon request of control unit 17.

[0038] For example, the memory 14 may store the operating time of the aerosol generating device 10, the maximum number of puffs, the current number of puffs, the number of times the battery 16 has been charged, the number of times the battery 16 has been discharged, at least one temperature profile, data on the user's inhalation pattern, data on charging and discharging, etc. Here, a puff may refer to a user's inhalation, and inhalation may be a situation in which the user inhales into the user's oral cavity, nasal cavity, or lungs through the mouth or nose.

[0039] The memory 14 may include at least one of a volatile memory (e.g., DRAM, SRAM, SDRAM, etc.) and a non-volatile memory (e.g., a flash memory, a hard disk drive (HDD), a solid-state drive (SSD), etc.).

[0040] The sensor module 15 may include at least one sensor.

[0041] For example, the sensor module 15 may include a sensor for detecting a puff (hereinafter, referred to as a puff sensor). Here, the puff sensor may be implemented by a proximity sensor such as an IR sensor, a pressure sensor, a gyro sensor, an acceleration sensor, a magnetic field sensor, or the like.

[0042] For example, the sensor module 15 may include a sensor for detecting a puff (hereinafter, referred to as a puff sensor). Here, the puff sensor may be implemented by a pressure sensor, a gyro sensor, an acceleration sensor, a magnetic field sensor, or the like.

[0043] For example, the sensor module 15 may include a sensor (hereinafter, referred to as a temperature sensor) for detecting the temperature of a heater included in the aerosol generation module 13, the temperature of an aerosol generating material, etc. Here, the heater included in the aerosol generation module 13 may also function as a temperature sensor. For example, the electrically resistive material of the heater may be a material having a temperature coefficient of resistance. The sensor module 15 may sense the temperature of the heater by measuring the resistance of the heater, which changes depending on the temperature.

[0044] For example, if a stick can be inserted into the main body of the aerosol generation device 10, the sensor module 15 can include a sensor that detects the insertion of the stick (hereinafter referred to as a stick detection sensor).

[0045] For example, in the case where the aerosol generation device 10 includes a cartridge, the sensor module 15 may include a sensor (hereinafter referred to as a cartridge detection sensor) that detects the attachment / detachment, position, etc. of the cartridge relative to the main body.

[0046] Here, the stick detection sensor and / or the cartridge detection sensor may be implemented using an inductance-based sensor, a capacitance-type sensor, a resistance sensor, a hall sensor (hall IC) using the hall effect, or the like.

[0047] For example, the sensor module 15 may include a voltage sensor that detects the voltage applied to a component (e.g., battery 16) provided in the aerosol generating device 10 and / or a current sensor that detects the current.

[0048] The battery 16 can supply power used for the operation of the aerosol generation device 10 under the control of the control unit 17. The battery 16 can supply power to other components provided in the aerosol generation device 10. For example, the battery 16 can supply power to a communication module included in the communication interface 11, an output device included in the input / output interface 12, a heater included in the aerosol generation module 13, etc.

[0049] The battery 16 may be a rechargeable battery or a disposable battery. For example, the battery 16 may be, but is not limited to, a lithium ion battery or a lithium polymer battery. For example, if the battery 16 is rechargeable, the charge rate (C-rate) of the battery 16 may be, but is not limited to, 10C and the discharge rate (C-rate) of the battery 16 may be, but is not limited to, 10C to 20C. For stable use, the battery 16 may be manufactured to ensure 80% or more of its total capacity even after 2000 charge / discharge cycles.

[0050] The aerosol generating device 10 may further include a protection circuit module (PCM), which is a circuit for protecting the battery 16. The protection circuit module (PCM) may be disposed adjacent to an upper surface of the battery 16. For example, in order to prevent overcharging and overdischarging of the battery 16, the protection circuit module (PCM) may cut off an electric path to the battery 16 when a short circuit occurs in a circuit connected to the battery 16, when an overvoltage is applied to the battery 16, when an overcurrent flows through the battery 16, etc.

[0051] The aerosol generating device 10 may further include a charging terminal to which power supplied from an external source is input. For example, a charging terminal is formed on one side of the body of the aerosol generating device 10, and the aerosol generating device 10 may charge the battery 16 using power supplied through the charging terminal. Here, the charging terminal may be a wired terminal for USB communication, a pogo pin, or the like.

[0052] The aerosol generation device 10 can also wirelessly receive power supplied from an external source via the communication interface 11. For example, the aerosol generation device 10 can receive power wirelessly using an antenna included in a communication module for wireless communication, and can charge the battery 16 using the wirelessly supplied power.

[0053] The control unit 17 can control the overall operation of the aerosol generation device 10. The control unit 17 is connected to each component provided in the aerosol generation device 10, and can transmit and / or receive signals between each component to control the overall operation of each component.

[0054] The control unit 17 may include at least one processor and may use the processor to control the overall operation of the aerosol generating device 10. Here, the processor may be a general processor such as a central processing unit (CPU). Of course, the processor may be a dedicated device such as an ASIC or a processor based on other hardware.

[0055] The control unit 17 can perform any one of a plurality of functions of the aerosol generation device 10. For example, the control unit 17 can execute any one of a plurality of functions of the aerosol generation device 10 (e.g., a preheating function, a heating function, a charging function, a cleaning function, etc.) according to the state of each component included in the aerosol generation device 10, a user's command received via the input / output interface 12, etc.

[0056] The control unit 17 can control the operation of each component included in the aerosol generation device 10 based on the data stored in the memory 14. For example, the control unit 17 can control the battery 16 to supply a predetermined amount of power to the aerosol generation module 13 for a predetermined period of time based on data about a temperature profile, a user's inhalation pattern, and the like stored in the memory 14.

[0057] The control unit 17 can determine the occurrence of a puff through a puff sensor included in the sensor module 15. For example, the control unit 17 can check a temperature change, a flow change, a pressure change, a voltage change, etc. in the aerosol generating device 10 based on a sensing value of the puff sensor, and can determine the occurrence of a puff according to the confirmed result based on the sensing value of the puff sensor.

[0058] The control unit 17 can control the operation of each component included in the aerosol generating device 10 depending on the presence or absence of a puff and / or the number of puffs. For example, the control unit 17 can control the heater temperature to be changed or maintained based on the temperature profile stored in the memory 14.

[0059] The control unit 17 can control to cut off the power supply to the heater under a predetermined condition, for example, when the stick is removed and the cartridge is separated, when the number of puffs reaches a preset maximum number of puffs, when no puffs are detected for a preset time or more, when the remaining amount of the battery 16 is less than a preset value, etc.

[0060] The control unit 17 may calculate the remaining amount of power (hereinafter, referred to as the remaining amount) stored in the battery 16. For example, the control unit 17 may calculate the remaining amount of the battery 16 based on the sensing values ​​of a voltage sensor and / or a current sensor included in the sensor module 15.

[0061] The control unit 17 may control the supply of power to the heater using at least one of a pulse width modulation (PWM) method and a proportional-integral-differential (PID) method.

[0062] For example, the control unit 17 can use a PWM method to control a current pulse having a predetermined frequency and duty ratio to be supplied to the heater. Here, the control unit 17 can control the power supplied to the heater by adjusting the frequency and duty ratio of the current pulse.

[0063] For example, the control unit 17 can determine a target temperature to be a control target based on the temperature profile. Here, the control unit 17 can control the power supplied to the heater using a PID method, which is a feedback control method based on a difference between the heater temperature and the target temperature, a value obtained by integrating the difference over time, and a value obtained by differentiating the difference over time.

[0064] Meanwhile, the PWM method and the PID method have been described as examples of control methods for supplying power to the heater, but the present invention is not limited thereto, and various control methods such as a Proportional-Integral (PI) method and a Proportional-Differential (PD) method can be used.

[0065] Meanwhile, the control unit 17 may control the heater to supply power under preset conditions. For example, when a cleaning function for cleaning a space into which the stick is inserted is selected according to a command input by the user via the input / output interface 12, the control unit 17 may control the heater to supply a predetermined amount of power.

[0066] 2 to 4 are diagrams illustrating an aerosol generating device according to an embodiment of the present disclosure.

[0067] According to various embodiments of the present invention, the aerosol generating device 10 can include a body 100 and / or a cartridge 200 .

[0068] 2, an aerosol generating device 10 according to one embodiment can include a body 100 and a cartridge 200. The body 100 can support the cartridge 200, which can contain an aerosol generating material.

[0069] According to one embodiment, the cartridge 200 may be configured to be detachable from the main body 100. According to another embodiment, the cartridge 200 may be configured integrally with the main body 100. For example, the cartridge 200 may be attached to the main body 100 by inserting at least a portion of the cartridge 200 into an internal space formed by the housing 101 of the main body 100.

[0070] The main body 100 may be formed in a structure that allows external air to flow into the main body 100 when the cartridge 200 is inserted. Here, the external air that has flowed into the main body 100 may flow to the user's mouth through the cartridge 200.

[0071] The control unit 17 can determine whether the cartridge 200 is attached / detached by a cartridge detection sensor included in the sensor module 15. For example, the cartridge detection sensor can transmit a pulse current through one terminal connected to the cartridge 200. Here, the cartridge detection sensor can detect whether the cartridge 200 is connected based on whether the pulse current is received through another terminal.

[0072] The cartridge 200 may include a first heater 210 for heating an aerosol generating substance and / or a storage unit 220 for storing the aerosol generating substance. For example, a liquid transmission means impregnated (containing) the aerosol generating substance may be disposed inside the storage unit 220. The electrically conductive track of the first heater 210 may be formed in a structure that wraps around the liquid transmission means. Here, an aerosol may be generated by heating the liquid transmission means by the first heater 210. Here, the liquid transmission means may include a wick made of cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

[0073] The cartridge 200 may include a mouthpiece 225. Here, the mouthpiece 225 may be a part that is inserted into the oral cavity of a user. The mouthpiece 225 may have an exhaust hole through which the aerosol is exhausted to the outside during a puff.

[0074] 3, the cartridge 200 may include an insertion space 230 into which the stick 20 can be inserted. For example, the cartridge 200 may include an insertion space formed by an inner wall (not shown) extending in a circumferential direction along a direction in which the stick 20 is inserted. Here, the insertion space may be formed by opening the inside of the inner wall upward and downward. The stick 20 may be inserted into the insertion space 230 formed by the inner wall.

[0075] The insertion space into which the stick 20 is inserted may be formed to have a shape corresponding to the shape of a portion of the stick 20 to be inserted into the insertion space. For example, if the stick 20 is formed to have a cylindrical shape, the insertion space may be formed to have a cylindrical shape.

[0076] When the stick 20 is inserted into the insertion space, the outer circumferential surface of the stick 20 is surrounded by the inner wall and may come into contact with the inner wall.

[0077] A part of the stick 20 is inserted into the insertion space 230 of the cartridge 200, and the remaining part can be exposed to the outside.

[0078] A user can inhale the aerosol while holding one end of the stick 20 in his / her mouth. The aerosol generated by the first heater 210 can be delivered to the user's mouth through the stick 20. Here, as the aerosol passes through the stick 20, a substance contained in the stick 20 is added to the aerosol, and the aerosol with the added substance can be inhaled into the user's mouth through one end of the stick 20.

[0079] The control unit 17 can monitor the number of puffs based on the sensing value of the puff sensor from the point when the stick 20 is inserted.

[0080] The control unit 17 can initialize the current number of puffs stored in the memory 14 when the inserted stick 20 is removed.

[0081] The cartridge 200 may include a second heater 215 for heating the stick 20. The second heater 215 may be disposed at a position in the cartridge 200 corresponding to the position of the stick 20 when the stick 20 is inserted into the insertion space 230. The second heater 215 may be composed of an electrically conductive heater and / or an induction heating heater. The second heater 215 may heat the inside and / or outside of the stick 20 using power supplied from the battery 16.

[0082] 4, an aerosol generating device 100 according to an embodiment may include a main body 100 supporting a cartridge 200 and a cartridge 200 storing an aerosol generating substance. The main body 100 may be configured so that the stick 20 can be inserted into the insertion space 130.

[0083] The aerosol generating device 100 may include a first heater 210 for heating the aerosol generating material stored in the cartridge 200 and a second heater 115 for heating the stick 20 inserted into the body 100. For example, the aerosol generating device 100 may generate an aerosol by heating the aerosol generating material stored in the cartridge 200 and the stick 20 using the first heater 210 and the second heater 115, respectively.

[0084] The stick 20 may be similar to a typical combustible cigarette. For example, the stick 20 may be divided into a first portion including an aerosol-generating substance and a second portion including a filter or the like. Alternatively, the second portion of the stick 20 may also include an aerosol-generating substance. For example, the aerosol-generating substance formed in the form of granules or capsules may be inserted into the second portion.

[0085] Hereinafter, an embodiment in which the stick 20 is inserted into the insertion space 130 formed in the housing 101 of the main body 100 will be described.

In addition, the filter rod 22 may further include at least one segment that performs another function, if necessary.

[0089] The stick 20 may have a diameter in the range of 5 mm to 9 mm and a length of about 48 mm, but is not limited thereto.

As an example, the stick 20 may be wrapped by one wrapper 24. As another example, the stick 20 may be wrapped by two or more wrappers 24 stacked on top of each other. For example, the tobacco rod 21 may be wrapped by a first wrapper 241. For example, the filter rod 22 may be wrapped by wrappers 242, 243, and 244. The tobacco rod 21 and the filter rod 22 wrapped by individual wrappers may be combined, and the entire stick 20 may be further wrapped by a third wrapper. When each filter rod 22 is composed of a plurality of segments, each segment may be wrapped by an individual wrapper 242, 243, and 244. The entire stick 20, in which the segments wrapped by the individual wrappers are combined, may be further wrapped by another wrapper.

Here, the sterilized paper (MFW) may be a paper that is specially manufactured to have improved tensile strength, water resistance, smoothness, etc., compared to general paper. For example, the basis weight of the fifth wrapper 245 may be in the range of 57 g / m2 to 63 g / m2. For example, the basis weight of the fifth wrapper 245 may be 60 g / m2. 2 The thickness of the fifth wrapper 245 may be in the range of 64 μm to 70 μm. For example, the thickness of the fifth wrapper 245 may be 67 μm.

[0095] The fifth wrapper 245 may include a predetermined material. Here, an example of the predetermined material may be, but is not limited to, silicon. For example, silicon may have properties such as heat resistance, which is less susceptible to change with temperature, oxidation resistance, resistance to various chemicals, water repellency, and electrical insulation. However, any material other than silicon that has the above-mentioned properties may be applied or coated onto the fifth wrapper 245 without any restrictions.

[0096] The fifth wrapper 245 can prevent the stick 20 from burning. For example, when the tobacco rod 21 is heated by the heater 210, the stick 20 may burn. Specifically, when the temperature rises above the flash point of any one of the materials contained in the tobacco rod 21, the stick 20 may burn. Even in such a case, the fifth wrapper 245 contains a non-flammable material, and therefore can prevent the stick 20 from burning.

[0097] In addition, the fifth wrapper 245 can prevent the main body 100 from being contaminated by a substance produced in the stick 20. A liquid substance can be produced in the stick 20 by the user's puff. For example, a liquid substance (e.g., moisture) can be produced as the aerosol produced in the stick 20 is cooled by the outside air. The fifth wrapper 245 wraps the stick 20, thereby preventing the liquid substance produced in the stick 20 from leaking out of the stick 20.

[0098] The tobacco rod 21 may include an aerosol-generating substance. For example, the aerosol-generating substance may include, but is not limited to, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. The tobacco rod 21 may also include other additives, such as flavoring agents, humectants, and / or organic acids. A flavoring liquid, such as menthol or a humectant, may be added to the tobacco rod 21 by being sprayed onto the tobacco rod 21.

[0099] The tobacco rod 21 can be manufactured in various ways. For example, the tobacco rod 21 can be manufactured from a sheet. For example, the tobacco rod 21 can be manufactured from a strand. For example, the tobacco rod 21 can be manufactured from a small piece obtained by cutting a tobacco sheet into small pieces. For example, the tobacco rod 21 can be surrounded by a thermally conductive material. For example, the thermally conductive material can be a metal foil such as aluminum foil, but is not limited thereto. For example, the thermally conductive material surrounding the tobacco rod 21 can uniformly distribute the heat transferred to the tobacco rod 21 and improve the thermal conductivity to the tobacco rod. Therefore, the tobacco taste can be improved. The thermally conductive material surrounding the tobacco rod 21 can function as a susceptor heated by an induction heater. Although not shown in the drawings, the tobacco rod 21 can further include an additional susceptor in addition to the thermally conductive material surrounding the outside.

When the filter rod 22 is composed of a plurality of segments, at least one of the plurality of segments may be manufactured into another shape.

[0101] The first segment of the filter rod 22 may be a cellulose acetate filter. For example, the first segment may be a tube-shaped structure having a hollow inside.

The diameter of the hollow included in the first segment may be an appropriate diameter within the range of 2 mm to 4.5 mm, but is not limited thereto.

[0102] The length of the first segment may be an appropriate length within the range of 4 mm to 30 mm, but is not limited thereto. For example, the length of the first segment may be 10 mm, but is not limited thereto.

[0103] The second segment of the filter rod 22 cools the aerosol generated by the heater 110 heating the tobacco rod 21. Thus, the user can inhale the aerosol that has been cooled to an appropriate temperature.

[0104] The length or diameter of the second segment may be determined in various ways depending on the shape of the stick 20. For example, the length of the second segment may be appropriately adopted within the range of 7 mm to 20 mm. Preferably, the length of the second segment may be about 14 mm, but is not limited thereto.

[0105] The second segment can be made by weaving polymeric fibers, in which case the flavor liquid can be applied to the fibers made from the polymer, or the second segment can be made by weaving together the fibers made from the polymer with separate fibers that have been coated with the flavor liquid, or the second segment can be formed from a crimped polymer sheet.

[0106] For example, the polymer may be made from a material selected from the group consisting of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polylactic acid (PLA), cellulose acetate (CA), and aluminum foil.

[0107] The second segment may be formed from woven polymer fibers or a crimped polymer sheet, such that the second segment includes one or more longitudinally extending channels, where the channels may be passageways through which a gas (e.g., air or aerosol) may pass.

Also, the aerosol cooling element may have a specific surface area of ​​about 10 mm 2 / mg and about 100mm 2 / mg of material.

[0109] Meanwhile, the second segment can include a thread containing a volatile flavor component, which can be, but is not limited to, menthol. For example, the thread can be loaded with a sufficient amount of menthol to provide 1.5 mg or more of menthol to the second segment.

[0110] The third segment of the filter rod 22 may be a cellulose acetate filter. The length of the third segment may be appropriately selected within a range of 4 mm to 20 mm. For example, the length of the third segment may be about 12 mm, but is not limited thereto.

[0111] The filter rod 22 may be manufactured to generate a flavor. For example, a flavoring liquid may be sprayed onto the filter rod 22. For example, a separate fiber coated with a flavoring liquid may be inserted into the filter rod 22.

Then, the entire stick 30 may be rewrapped by a fifth wrapper 355.

[0117] Also, at least one perforation 36 may be formed in the fifth wrapper 355. For example, but not limited to, the perforation 36 may be formed in a region surrounding the tobacco rod 31.

[0131] 7 to 12 are diagrams illustrating the configuration of an aerosol generating device according to an embodiment of the present disclosure.

[0132] Referring to FIG. 7, the aerosol generating device 10 may include a housing 101 having an insertion space 130 formed therein, a heater 110, a number of sensors 151, 153, 155, a battery 16, and / or a printed circuit board 700.

[0133] The insertion space 130 may be a space formed in the housing 101 that constitutes the exterior of the aerosol generating device 10. The insertion space 130 may have one end opened to form an opening. The insertion space 130 may be exposed to the outside through the opening. The opening may be defined as one end of the insertion space 130.

[0134] The stick 20 may be inserted into the insertion space 130. The insertion space 130 may be formed in a shape corresponding to the shape of the stick 20. For example, if the cross section of the stick 20 is formed in a cylindrical shape, the insertion space 130 may be formed in a cylindrical shape. A part of the stick 20 may be inserted into the insertion space 130. The remaining part of the stick 20 excluding the part inserted into the insertion space 130 may be exposed to the outside.

[0135] The heater 110 may be disposed adjacent to the insertion space 130. The heater 110 may heat the inside and / or outside of the stick 20 using power supplied from the battery 16. The heater 110 may be composed of an electrically conductive heater and / or an induction heater.

[0136] The inductive sensor 151 may include at least one coil. The coil of the inductive sensor 151 may be disposed adjacent to the insertion space 130. For example, when a magnetic field changes around a coil through which a current flows, the characteristics of the current flowing through the coil may change according to Faraday's law of electromagnetic induction. Here, the characteristics of the current flowing through the coil may include the frequency, current value, voltage value, inductance value, impedance value, etc. of the AC current.

[0137] The induction sensor 151 may output a signal corresponding to the characteristics of the current flowing through the coil. For example, the induction sensor 151 may output a signal corresponding to the inductance value of the coil. For example, when the stick 20 including the first wrapper 241 made of a metallic material is inserted into the insertion space 230, the magnetic field around the coil may change due to the first wrapper 241. Here, the inductance value of the coil may change in response to the change in the magnetic field due to the first wrapper 241.

[0138] According to an embodiment, the aerosol generating device 10 may include a capacitance sensor. The capacitance sensor may include an electrode formed to surround at least a portion of the insertion space 130. The electrode may be made of a conductive material. For example, the electrode may be made of a metal material having high conductivity, such as gold (Au), silver (Ag), copper (Cu), or aluminum (Al).

[0139] The signal level of the capacitance sensor may represent a value corresponding to the capacitance around the electrodes provided in the capacitance sensor. When the stick 20 is inserted into the insertion space 130, the capacitance around the electrodes provided in the capacitance sensor may change due to the stick 20 inserted into the insertion space 130.

[0140] Meanwhile, the degree of change in the signal level of the capacitance sensor may correspond to the amount of moisture contained in the stick 20. For example, as the amount of moisture contained in the stick 20 increases, the degree of change in the signal level of the capacitance sensor 150 due to the insertion of the stick 20 into the insertion space 130 may increase.

[0141] The proximity sensor 153 can sense an object inserted into and placed nearby the insertion space 130. The proximity sensor 153 may be placed toward the insertion space 130. The proximity sensor 153 may be placed adjacent to a lower end of the insertion space 130.

[0142] The proximity sensor 153 may be an optical proximity sensor. In the following, a description will be given of an example in which the proximity sensor 153 is an optical proximity sensor. The proximity sensor 153 can emit light toward the insertion space 130. The proximity sensor 153 can include a light-emitting element that emits light toward the insertion space 130 and a light-receiving element that outputs a signal corresponding to the incident light.

[0143] The light emitting element can emit infrared light with a wavelength of 780 nm to 1 mm. The light emitting element can include a light emitting diode (LED), an organic light emitting diode (OLED), a laser diode (LD), or the like as a light source. The proximity sensor 153 can include a first light collecting element that collects light generated by the light source toward the insertion space 130. Here, the first light collecting element can be composed of an imaging lens, a diffractive optical element (DOE), or the like.

[0144] The light receiving element may include a photodiode, a phototransistor, etc. that react to light. The proximity sensor 153 may include a second light collecting element that collects light irradiated from a light source and reflected (hereinafter, reflected light). For example, the reflected light collected by the second light collecting element may be transmitted to the photodiode. Here, the second light collecting element may include a lens that receives the reflected light incident from a predetermined direction.

[0145] The proximity sensor 153 may further include an optical filter that selectively transmits light in a specific wavelength range. For example, when the light source irradiates infrared light with a wavelength of 780 nm to 1 mm, the optical filter may be an infrared pass filter that selectively passes infrared light.

[0146] According to an embodiment, the aerosol generating device 10 may further include a color sensor that detects the hue of an object. The color sensor may detect a value for an optical characteristic corresponding to the hue of the object based on light reflected from the object. For example, the optical characteristic may be a wavelength of light. The color sensor may be embodied as an integral part of the proximity sensor 153, or may be embodied as a separate component separate from the proximity sensor 153. In the present disclosure, the color sensor may be embodied as an integral part of the proximity sensor 153, but is not limited thereto.

[0147] At least a part of the wrapper 24 constituting the stick 20 may change color due to the aerosol. The color sensor may be disposed in a position corresponding to where at least a part of the wrapper 24, the color of which changes due to the aerosol, is disposed when the stick 20 is inserted into the insertion space 130. For example, before a user uses the stick 20, the color of at least a part of the wrapper 24 may be a first color. Here, as the aerosol generated by the aerosol generating device 10 passes through the stick 20, at least a part of the wrapper 24 may be wetted by the aerosol, so that the color of at least a part of the wrapper 24 may change to a second color. Meanwhile, the color of at least a part of the wrapper 24 may be maintained at the second color after changing from the first color to the second color.

[0148] The puff sensor 155 can sense the flow of gas flowing into the housing 101. The puff sensor 155 can output a signal corresponding to the puff. For example, the puff sensor 155 can output a signal corresponding to the internal pressure of the aerosol generation device 10. Here, the internal pressure of the aerosol generation device 10 can correspond to the pressure of an airflow passage through which the gas flows. In the present embodiment, the puff sensor 155 is described as being embodied by a pressure sensor that outputs a signal corresponding to the internal pressure of the aerosol generation device 10, but is not limited thereto.

The sensors 151, 153, and 155 may receive power through the corresponding flexible printed circuit boards 720, 730, and 740, respectively. Power lines corresponding to the sensors 151, 153, and 155 may be configured to be electrically isolated from each other.

Based on the origin, the direction toward +y can be the forward direction, and the direction toward -y can be the backward direction. The z-axis direction can be defined as the up-down direction of the aerosol generation device 10. Here, based on the origin, the direction toward +z can be the upward direction, and the direction toward -z can be the downward direction.

[0155] The upper body 810 may accommodate various components required for generating aerosol, such as the heater 110 and the sensors 151, 153, and 155, inside. The upper body 810 may have an insertion opening 811. The insertion opening 811 may be formed by opening the upper side of the upper body 810. The insertion opening 811 may be formed at a position corresponding to the insertion space 130. The insertion opening 811 may be connected to one end or an upper end of the insertion space 130.

[0157] The cover 813 may be movably installed. The cover 813 may move to open and close the insertion space 130. For example, the cover 813 may slide backward along the upper surface of the upper body 810 to open the insertion space 130. For example, the cover 813 may slide forward along the upper surface of the upper body 810 to close the insertion space 130. Meanwhile, the movement manner of the cover 813 is not limited to the sliding movement manner. For example, the cover 813 may open and close the insertion space 130 not only by a non-rotating manner such as a sliding movement but also by a rotating manner such as a tilt or a hinge.

[0161] The mount 821 may include a through hole. At least one of the flexible printed circuit boards 710-740 may be disposed to pass through the through hole. The flexible printed circuit boards 710-740 may be electrically isolated from one another. By electrically isolating the multiple sensors 151, 153, 155 from one another, it is possible to minimize the effect of an error occurring in any one of the multiple sensors 151, 153, 155 on the operation of the other sensors.

[0162] The flexible printed circuit boards 710-740 disposed through the through holes may be electrically connected to the printed circuit board 700 disposed inside the lower body 820. For example, the flexible printed circuit boards 710-740 may be coupled to a plurality of connectors mounted on the printed circuit board 700, respectively. For example, one end of the first flexible printed circuit board 710 may be electrically connected to the heater 110, and the other end of the first flexible printed circuit board 710 may be electrically connected to a first connector corresponding to the battery 16 among the components mounted on the printed circuit board 700. For example, one end of the second flexible printed circuit board 720 may be electrically connected to the induction sensor 150, and the other end of the second flexible printed circuit board 720 may be electrically connected to a second connector corresponding to the controller 17 among the components mounted on the printed circuit board 700.

[0163] 10 to 12, the aerosol generating device 10 may include a power supply circuit that supplies power to a predetermined configuration. In the present disclosure, a power supply circuit 1000 that adjusts the supply of power to the puff sensor 155 will be described as an example, but is not limited thereto.

[0164] The power supply circuit 1000 may be electrically connected to the control unit 17. The power supply circuit 1000 may be electrically connected to the proximity sensor 153. The power supply circuit 1000 may be electrically connected to the puff sensor 155.

[0165] The power supply circuit 1000 may include a first node N1 electrically connected to the proximity sensor 153, a second node N2 electrically connected to the puff sensor 155, a third node N3 electrically connected to the control unit 17, and / or a fourth node N4 to which power is input.

[0166] The power supply circuit 1000 can adjust the supply of power to the puff sensor 155. The power supply circuit 1000 can adjust the supply of power to the puff sensor 155 based on a signal received from the control unit 17 and / or the proximity sensor 153. For example, the power supply circuit 1000 can supply power to the puff sensor 155 when a predetermined signal corresponding to the insertion of the stick 20 is input from the proximity sensor 153. For example, the power supply circuit 1000 can supply power to the puff sensor 155 when a predetermined signal corresponding to the state of the proximity sensor 153 is input from the control unit 17.

[0167] The power supply circuit 1000 may include at least one switching element. The switching element may be operated to adjust the supply of power to the puff sensor 155. The switching element included in the power supply circuit 1000 may be operated in response to a signal received from the control unit 17 and / or the proximity sensor 153.

[0168] The power supply circuit 1000 may include a first switching element S1 disposed between a third node N3 and a ground terminal GND. The power supply circuit 1000 may include a second switching element S2 disposed between a second node N2 and a fourth node N4.

[0169] The first switching element S1 may be operated by a signal output from the proximity sensor 153. The proximity sensor 153 may output a signal Sp corresponding to the insertion of an object (hereinafter, referred to as an insertion signal) to the first node N1 based on the insertion of an object into the insertion space 130. For example, the state of the first node N1 corresponding to the input of the insertion signal Sp may be high, and the state of the first node N1 corresponding to the absence of the input of the insertion signal Sp may be low.

[0170] The first switching element S1 may be turned on by receiving an insert signal Sp through a first node N1. When the first switching element S1 is turned on, the third node N3 may be electrically connected to the ground terminal GND. For example, when the insert signal Sp is input through the first node N1, the state of the first node N1 changes from low to high, thereby turning on the first switching element S1.

[0171] The second switching element S2 may operate according to the state of the third node N3. For example, the second switching element S2 may be turned off when the third node N3 is in a high state, and may be turned on when the third node N3 is in a low state. When the second switching element S2 is turned on, power input via the fourth node N4 may be supplied to the puff sensor 155.

[0172] According to an embodiment, the insert signal Sp is input through the first node N1 to turn on the first switching element S2, thereby electrically connecting the third node N3 to the ground terminal GND. Here, since the third node N3 is electrically connected to the ground terminal GND, the state of the third node N3 may change from high to low.

[0173] The control unit 17 may determine the state of the proximity sensor 153. For example, a liquid substance generated within the upper body 810 may interfere with the operation of a light emitting element or a light receiving element included in the proximity sensor 153, or may cause a short circuit in a power line or a signal line of the proximity sensor 153. Here, the control unit 17 may determine the state of the proximity sensor 153 based on a signal received from the proximity sensor 153.

[0174] According to an embodiment, the control unit 17 may determine the state of the proximity sensor 153 depending on whether a predetermined signal is received from the proximity sensor 153. For example, the control unit 17 may determine that the state of the proximity sensor 153 is defective when the control unit 17 does not receive a response signal from the proximity sensor 153 in response to a signal transmitted to the proximity sensor 153.

[0175] According to an embodiment, the control unit 17 may determine that the state of the proximity sensor 153 is in a defective state when the signal received from the proximity sensor 153 and the signal received from the induction sensor 151 do not correspond to each other. For example, the control unit 17 may determine that the state of the proximity sensor 153 is in a defective state when the stick 20 is detected by the induction sensor 151 and not by the proximity sensor 153. For example, the control unit 17 may determine that the state of the proximity sensor 153 is in a defective state when the stick 20 is not detected by the induction sensor 151 and is detected by the proximity sensor 153.

[0176] The control unit 17 can output a signal corresponding to the state of the proximity sensor 153 to the power supply circuit 1000. The signal corresponding to the state of the proximity sensor 153 output from the control unit 17 can be input to the power supply circuit 1000 via a third node N3. For example, when the state of the proximity sensor 153 is a defective state, the control unit 17 can output a signal corresponding to the defective state (hereinafter, referred to as a defective signal) Sc. For example, when the state of the proximity sensor 153 is a steady state, the control unit 17 can output a signal corresponding to the steady state (hereinafter, referred to as a normal signal).

[0177] According to an embodiment, the fault signal Sc inputted through the third node N3 may be a signal corresponding to the ground terminal GND. For example, when a normal signal is inputted to the power supply circuit 1000 through the third node N3, the state of the third node N3 may be high. When the fault signal Sc is inputted to the power supply circuit 1000 through the third node N3, the state of the third node N3 may correspond to the ground terminal GND. Here, when the state of the third node N3 corresponds to the ground terminal GND, the state of the third node N3 may be changed from high to low.

[0178] Meanwhile, when the state of the proximity sensor 153 is defective, the control unit 17 can deactivate the function of the proximity sensor 153. For example, when the state of the proximity sensor 153 is defective, the control unit 17 can control a power supply circuit that supplies power to the proximity sensor 153 so as to cut off the supply of power to the proximity sensor 153.

[0179] FIG. 13 is a flow chart illustrating a method of operating an aerosol generating device according to one embodiment of the present disclosure.

[0180] 13, in operation S1301, the aerosol generation device 10 may set the proximity sensor 153 to control the supply of power to the puff sensor 155. According to one embodiment, in a state in which the proximity sensor 153 is set to control the supply of power to the puff sensor 155, the operation of each component provided in the aerosol generation device 10 may be started.

[0181] In operation S1302, the aerosol generation device 10 can determine that the communication state between the control unit 17 and the proximity sensor 153 is good. For example, the control unit 17 of the aerosol generation device 10 can transmit a signal to the proximity sensor 153. Here, if a response signal in response to the signal transmitted by the control unit 17 to the proximity sensor 153 is not output from the proximity sensor 153, the aerosol generation device 10 can determine that the state of the proximity sensor 153 is bad.

[0182] In operation S1303, when the communication state between the control unit 17 and the proximity sensor 153 is good, the aerosol generating device 10 can determine whether the proximity sensor 153 detects the stick 20. For example, the aerosol generating device 10 can determine whether an object has been inserted into the insertion space 130 based on the time from when the light-emitting element irradiates light to when the light-receiving element reacts to the reflected light.

[0183] When no object is inserted into the insertion space 130, the light irradiated toward the light-emitting insertion space 130 can be reflected by the inner wall forming the insertion space 130 and enter the light-receiving element. On the other hand, when an object is inserted into the insertion space 130, at least a part of the light irradiated from the light-emitting element toward the insertion space 130 can be reflected by the object inserted into the insertion space 130 and enter the light-receiving element before being reflected by the inner wall forming the insertion space 130. Therefore, the aerosol generating device 10 can determine that the stick 20 is inserted into the insertion space 130 when the time from when the light-emitting element irradiates light to when the light-receiving element reacts to the reflected light is less than a predetermined time.

[0184] According to an embodiment, the aerosol generating device 10 may determine whether a stick 20 has been inserted into the insertion space 130 based on the hue of the object inserted into the insertion space 130 sensed via a color sensor. For example, the aerosol generating device 10 may determine that a new stick has been inserted into the insertion space 130 when the hue of the object inserted into the insertion space 130 is a first hue. For example, the aerosol generating device 10 may determine that a used stick has been inserted into the insertion space 130 when the hue of the object inserted into the insertion space 130 is a second hue.

[0185] According to an embodiment, the aerosol generating device 10 may determine whether the stick 20 has been inserted into the insertion space 130 based on the capacitance around the insertion space 130 detected via a capacitance sensor. For example, the aerosol generating device 10 may determine that the stick 20 has been inserted into the insertion space 130 when the degree of change in the level of the signal of the capacitance sensor is equal to or greater than a predetermined minimum level. For example, the aerosol generating device 10 may determine that the used stick 20 has been inserted into the insertion space 130 when the degree of change in the level of the signal of the capacitance sensor is equal to or greater than a specific level that is greater than the minimum level.

[0186] In operation S1304, when the stick 20 is not detected by the proximity sensor 153, the aerosol generation device 10 may determine whether the induction sensor 151 detects the stick 20. For example, the aerosol generation device 10 may determine that the stick 20 is inserted into the insertion space 130 when an inductance value corresponding to a signal from the induction sensor 151 changes to a value equal to or greater than a predetermined value. For example, the aerosol generation device 10 may determine that the stick 20 is inserted into the insertion space 130 when an inductance value corresponding to a signal from the induction sensor 151 exceeds a predetermined value.

[0187] When the stick 20 is not detected by the induction sensor 151 and the proximity sensor 153, the aerosol generating device 10 can continuously monitor whether the stick 20 is inserted into the insertion space 130 via the induction sensor 151 and the proximity sensor 153.

[0188] When the stick 20 is detected by the proximity sensor 153 in operation S1305, the aerosol generation device 10 can supply power to the puff sensor 155. For example, the power supply circuit 1000 can supply power to the puff sensor 155 in response to an insertion signal Sp output from the proximity sensor 153 in response to the insertion of the stick 20.

[0189] In operation S1306, the aerosol generating device 10 can determine whether the induction sensor 151 detects the stick 20.

[0190] The aerosol generation device 10 may be configured to have the control unit 17 control the supply of power to the puff sensor 155 in operation S1307. The aerosol generation device 10 may be configured to have the control unit 17 control the supply of power to the puff sensor 155 when the state of the proximity sensor 153 is poor. For example, the aerosol generation device 10 may be configured to have the control unit 17 control the supply of power to the puff sensor 155 when the communication state between the control unit 17 and the proximity sensor 153 is poor. For example, the aerosol generation device 10 may be configured to have the control unit 17 control the supply of power to the puff sensor 155 when the stick 20 is detected by any one of the induction sensor 151 and the proximity sensor 153.

[0191] Meanwhile, when the state of the proximity sensor 153 is a defective state, the aerosol generation device 10 can deactivate the function of the proximity sensor 153. Here, when the function of the proximity sensor 153 is deactivated, the output of the insertion signal Sp can be interrupted.

[0192] When the control unit 17 is set to control the supply of power to the puff sensor 155 in operation S1308, the aerosol generating device 10 can monitor whether the induction sensor 151 detects the stick 20.

[0193] When the aerosol generation device 10 detects the stick 20 through the induction sensor 151 in operation S1309, the aerosol generation device 10 can supply power to the puff sensor 155. For example, when the control unit 17 of the aerosol generation device 10 detects the stick 20 through the induction sensor 151, the control unit 17 can output a fault signal Sc to the power supply circuit 1000. Here, the power supply circuit 1000 can supply power to the puff sensor 155 according to the fault signal Sc output from the control unit 17.

[0194] The aerosol generating device 10 may supply power to the heater 110 in operation S1310. For example, when the aerosol generating device 10 detects the stick 20 through the induction sensor 151 and the proximity sensor 153, the aerosol generating device 10 may supply power to the heater 110. For example, when the aerosol generating device 10 detects the stick 20 through the induction sensor 151 in a state in which the control unit 17 is set to control the supply of power to the puff sensor 155, the aerosol generating device 10 may supply power to the heater 110.

[0195] According to an embodiment, the aerosol generating device 10 may determine whether to supply power to the heater 110 based on the color of the stick 20 detected through the color sensor. For example, when the aerosol generating device 10 detects the stick 20 through the induction sensor 151 and the proximity sensor 153, the aerosol generating device 10 may check the color of the stick 20 detected through the color sensor. Here, when it is determined that the color of the stick 20 is the second color, the aerosol generating device 10 may cut off the supply of power to the heater 110.

[0196] As mentioned above, in accordance with at least one embodiment of the present disclosure, upon insertion of the stick 20, certain sensors can be immediately activated.

[0197] Furthermore, according to at least one of the embodiments of the present disclosure, the configuration for controlling the power supply to a specific sensor can be appropriately changed depending on the situation.

[0198] Furthermore, according to at least one of the embodiments of the present disclosure, it is possible to minimize the influence of an error occurring in any one of a plurality of sensors on the other sensors.

The first sensor 153 may output a first signal corresponding to the state of the insertion space 130 to the control unit 17, and a second signal corresponding to the insertion of the stick into the insertion space 130 to the power supply circuit 1000. When the state of the first sensor 153 is a defective state, the control unit 17 may output a third signal corresponding to the defective state to the power supply circuit 1000. The power supply circuit 1000 may supply the power to the second sensor 155 based on the reception of at least one of the second signal and the third signal.

The third node N3 may correspond to the ground GND by receiving the third signal via the third node N3.

[0203] According to another aspect of the present disclosure, the control unit 17 can determine that the condition of the first sensor 153 is poor when the control unit 17 does not receive a response signal from the first sensor 153 in response to a signal transmitted to the first sensor 153.
