Description

TECHNICAL FIELD

[0001] The disclosure relates to a protection circuit module and an aerosol-generating device including the same. BACKGROUND

[0002] An aerosol-generating device is a device that extracts certain components from a medium or a substance by forming an aerosol. The medium can include a multi-component substance. The substance included in the medium can be a multi-component flavoring substance. For example, the substance included in the medium can include a nicotine component, a Chinese medicine component, and / or a coffee component. Recently, various researches have been conducted on aerosol-generating devices.

[0003] In addition, the aerosol-generating device can generate an aerosol using power of a battery. However, the battery is composed of various flammable materials. Therefore, the battery can generate heat or explode due to overvoltage, overcurrent, overcharge, or external physical impact. Accordingly, a conventional general aerosol-generating device includes a protection circuit module (PCM) in order to prevent the battery from generating heat or exploding. The protection circuit module (PCM) can sense and process an abnormal state of the battery based on a voltage applied to the battery, a current flowing through the battery, or a temperature of the battery.

[0004] The conventional protection circuit module (PCM) is configured such that a plurality of active elements and passive elements are separately mounted on one surface or both surfaces of a printed circuit board (PCB). In the case where foreign substances such as moisture or dust enter the aerosol-generating device, the circuit elements mounted on the printed circuit board are directly exposed to the foreign substances. For example, when a fine crack is formed in the internal structure of the aerosol-generating device, an aerosol enters the aerosol-generating device. In this case, the protection circuit module (PCM) can malfunction, and thus cannot reliably prevent the battery from generating heat or exploding. In addition, in the case where the circuit elements mounted on the printed circuit board are covered by a separate component (for example, a piece of insulating tape), the foreign substances can reach the circuit elements through a fine gap. SUMMARY

[0005] TECHNICAL PROBLEM

[0006] An object of the disclosure is to solve the above and other problems.

[0007] Another object of the disclosure is to provide a protection circuit module (PCM) capable of preventing elements constituting the protection circuit module from being exposed to foreign substances and an aerosol-generating device including the same.

[0008] TECHNICAL SOLUTION

[0009] A protection circuit module according to an embodiment of the disclosure for achieving the above and other objects can be electrically connected to a battery to control at least one function of the battery.

[0011] Advantageous Effects

[0012] According to at least one embodiment of the disclosure, elements included in an integrated circuit (IC) for protecting a battery can be prevented from being exposed to foreign substances.

[0013] In addition, according to at least one embodiment of the disclosure, a battery temperature sensor can be more reliably prevented from being damaged due to foreign substances, as compared to a case in which a separate battery temperature sensor is disposed adjacent to the battery.

[0026] Figure 1 is a block diagram of an aerosol generating device according to an embodiment of the disclosure.

[0027] Referring to Figure 1 , the aerosol generating device 100 can include a communication interface 110, an input / output interface 120, an aerosol generating module 130, a storage 140, a sensor module 150, a battery 160, and / or a controller 170.

[0028] In one embodiment, the aerosol generating device 100 can consist of only the main body. In this case, components included in the aerosol generating device 100 can be located in the main body. In another embodiment, the aerosol generating device 100 can consist of a cartridge containing an aerosol generating material and the main body. In this case, components included in the aerosol generating device 100 can be located in at least one of the main body or the cartridge.

[0029] The communication interface 110 can include at least one communication module for communicating with an external device and / or a network. For example, the communication interface 110 can include a communication module for wired communication, such as a universal serial bus (USB). For example, the communication interface 110 can include a communication module for wireless communication, such as wireless fidelity (Wi-Fi), Bluetooth, Bluetooth low energy (BLE), ZigBee, or near field communication (NFC).

[0030] The input / output interface 120 can include an input device (not shown) for receiving a command from a user and / or an output device (not shown) for outputting information to the user. For example, the input device can include a touch panel, a physical button, a microphone, or the like. For example, the output device can include a display device for outputting visual information, such as a display or a light emitting diode (LED), an audio device for outputting audible information, such as a speaker or a buzzer, a motor for outputting tactile information such as a haptic effect, or the like.

[0031] The input / output interface 120 can transmit data corresponding to a command input by a user through an input device to another component (or other component) of the aerosol generating device 100. The input / output interface 120 can output information corresponding to data received from another component (or other component) of the aerosol generating device 100 through an output device.

[0032] The aerosol generating module 130 can generate an aerosol from an aerosol generating material. Here, the aerosol generating material can be a liquid, solid, or gel material capable of generating an aerosol, or a combination of two or more aerosol generating materials.

[0033] According to an embodiment, the liquid aerosol generating material can be a liquid including a tobacco-containing material having a volatile tobacco flavor component. According to another embodiment, the liquid aerosol generating material can be a liquid including a non-tobacco material. For example, the liquid aerosol generating material can include water, a solvent, nicotine, a plant extract, a flavoring essence, a flavoring agent, a vitamin mixture, or the like.

[0034] The solid aerosol generating material can include a solid material based on a tobacco raw material, such as reconstituted tobacco sheet, cut tobacco, or granular tobacco. In addition, the solid aerosol generating material can include a solid material having a taste control agent and a flavoring material. For example, the taste control agent can include calcium carbonate, sodium bicarbonate, calcium oxide, etc. For example, the flavoring material can include a natural material such as herb particles, or can include a material containing an aromatic component (e.g., silicon dioxide, zeolite, or dextrin).

[0035] In addition, the aerosol generating material can further include an aerosol former such as glycerol or propylene glycol.

[0036] The aerosol generating module 130 can include at least one heater (not shown).

[0037] The aerosol generating module 130 can include an electric resistance heater. For example, the electric resistance heater can include at least one electrically conductive track. The electric resistance heater can be heated as an electric current flows through the electrically conductive track. At this time, the aerosol generating material can be heated by the heated electric resistance heater.

[0038] The electrically conductive track can include an electrically resistive material. In one example, the electrically conductive track can be formed of a metallic material. In another example, the electrically conductive track can be formed of a ceramic material, carbon, a metal alloy, or a composite of a ceramic material and a metal.

[0039] The electric resistance heater can include an electrically conductive track formed in any one of various shapes. For example, the electrically conductive track can be formed in any one of a tubular shape, a plate shape, a needle shape, a rod shape, and a coil shape.

[0040] The aerosol generating module 130 can include a heater using an induction heating method. For example, the induction heater can include an electrically conductive coil. The induction heater can generate an alternating magnetic field periodically changing direction by adjusting an electric current flowing through the electrically conductive coil. At this time, when the alternating magnetic field is applied to a magnet, energy loss can occur in the magnet due to eddy current loss and magnetic hysteresis loss. In addition, and the lost energy can be released as heat energy. Accordingly, the aerosol generating material disposed adjacent to the magnet can be heated. Here, an object that generates heat due to a magnetic field can be referred to as a susceptor.

[0041] Furthermore, the aerosol generating module 130 can generate ultrasonic vibrations, thereby generating an aerosol from the aerosol generating material.

[0042] The aerosol generating module 130 can be referred to as a cartomizer, an atomizer, or a cartomizer.

[0043] The memory 140 can store a program for processing and controlling various signals in the controller 170, and can store processed data and data to be processed.

[0044] For example, the memory 140 can store applications designed to perform various tasks that can be processed by the controller 170. The memory 140 can selectively provide some of the stored applications in response to a request from the controller 170.

[0045] For example, the memory 140 can store data about an operation time of the aerosol-generating device 100, a maximum number of puffs, a current number of puffs, at least one temperature profile, at least one power profile, and a user inhalation pattern. Here, "puff" means inhalation of a user. "Inhalation" means an act of a user bringing air or other substances into the user's mouth, nose, or lungs through the user's mouth or nose.

[0046] The memory 140 can include at least one of a volatile memory (for example, a dynamic random access memory (DRAM), a static random access memory (SRAM), or a synchronous dynamic random access memory (SDRAM)), a non-volatile memory (for example, a flash memory), a hard disk drive (HDD), or a solid state drive (SSD).

[0047] The sensor module 150 can include at least one sensor.

[0048] For example, the sensor module 150 can include a sensor for sensing a puff (hereinafter referred to as "puff sensor"). In this case, the puff sensor can 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.

[0049] For example, the sensor module 150 can include a sensor for sensing a temperature of a heater included in the aerosol-generating module 130 and a temperature of the aerosol-generating material (hereinafter referred to as "temperature sensor"). In this case, the heater included in the aerosol-generating module 130 can also function as a temperature sensor. For example, the electrically resistive material of the heater can be a material having a predetermined temperature coefficient of resistance. The sensor module 150 can measure the resistance of the heater that varies according to the temperature, thereby sensing the temperature of the heater.

[0050] For example, in a case in which the main body of the aerosol-generating device 100 is formed to allow a cigarette to be inserted therein, the sensor module 150 can include a sensor for sensing insertion of the cigarette (hereinafter referred to as "cigarette detection sensor").

[0051] For example, in a case in which the aerosol-generating device 100 includes a cartridge, the sensor module 150 can include a sensor for sensing installation / dismounting of the cartridge and a position of the cartridge (hereinafter referred to as "cartridge detection sensor").

[0052] In this context, the cigarette detection sensor and / or cartridge detection sensor can be implemented as an inductive sensor, a capacitive sensor, a resistive sensor, or a Hall sensor (or Hall IC) using the Hall effect.

[0053] For example, sensor module 150 may include a voltage sensor for sensing the voltage applied to a component (e.g., battery 160) disposed in aerosol generating apparatus 100 and / or a current sensor for sensing current.

[0054] Battery 160 can supply power for the operation of aerosol generating apparatus 100 under the control of controller 170. Battery 160 can also supply power to other components disposed in aerosol generating apparatus 100. For example, battery 160 can supply power to a communication module included in communication interface 110, an output device included in input / output interface 120, and a heater included in aerosol generating module 130.

[0055] Battery 160 can be a rechargeable battery or a disposable battery. For example, battery 160 can be a lithium-ion (Li-ion) battery or a lithium-polymer (Li-polymer) battery. However, this disclosure is not limited thereto. For example, when battery 160 is rechargeable, its charge rate (C-rate) can be 10C, and its discharge rate (C-rate) can be from 10C to 20C. However, this disclosure is not limited thereto. In addition, for stable use, battery 160 can be manufactured such that even after performing 2000 charge / discharge cycles, 80% or more of the total capacity can be maintained.

[0056] The aerosol generating apparatus 100 may also include a power terminal (not shown) for inputting power supplied from an external source. For example, a power cord may be connected to the power terminal located on one side of the main body of the aerosol generating apparatus 100. The aerosol generating apparatus 100 can use the power supplied through the power cord connected to the power terminal to charge the battery 160. In this case, the power terminal may be a wired terminal for USB communication.

[0057] The aerosol generating device 100 can wirelessly receive power supplied from an external source via the communication interface 110. For example, the aerosol generating device 100 can use an antenna included in a communication module for wireless communication to wirelessly receive power. The aerosol generating device 100 can use the wirelessly supplied power to charge the battery 160.

[0058] The controller 170 controls the overall operation of the aerosol generating apparatus 100. The controller 170 can be connected to various components disposed within the aerosol generating apparatus 100. The controller 170 can send signals to and / or receive signals from the various components, thereby controlling the overall operation of the various components.

[0059] The controller 170 can include at least one processor. The controller 170 can control the overall operation of the aerosol generating device 100 using the processor included therein. Here, the processor can be a general-purpose processor such as a central processing unit (CPU). Of course, the processor can be a dedicated device such as an application-specific integrated circuit (ASIC), or can be any one of other hardware-based processors.

[0060] The controller 170 can perform any one of a plurality of functions of the aerosol generating device 100. For example, the controller 170 can perform any one of a plurality of functions (e.g., a preheating function, a heating function, a charging function, and a cleaning function) of the aerosol generating device 100 according to the state of each component provided in the aerosol generating device 100 and a user command received through the input / output interface 120.

[0061] The controller 170 can control the operation of each component provided in the aerosol generating device 100 based on data stored in the memory 140. For example, the controller 170 can control the supply of a predetermined amount of power from the battery 160 to the aerosol generating module 130 for a predetermined time based on data stored in the memory 140 regarding a temperature profile, a power profile, and a user puffing pattern.

[0062] The controller 170 can determine the occurrence or nonoccurrence of puffing using a puff sensor included in the sensor module 150. For example, the controller 170 can check a temperature change, a flow change, a pressure change, and a voltage change in the aerosol generating device 100 based on a value sensed by the puff sensor. The controller 170 can determine the occurrence or nonoccurrence of puffing based on the value sensed by the puff sensor.

[0063] The controller 170 can control the operation of each component provided in the aerosol generating device 100 according to the occurrence or nonoccurrence of puffing and / or the number of puffs. For example, upon determining that puffing has occurred, the controller 170 can perform control so that power is supplied to the heater according to a power profile stored in the memory 140. For example, the controller 170 can perform control so that the temperature of the heater changes according to the number of puffs based on a temperature profile stored in the memory 140.

[0064] The controller 170 can perform control so that the supply of power to the heater is interrupted according to a predetermined condition. For example, the controller 170 can perform control so that the supply of power to the heater is interrupted when a cigarette is removed, when a cartridge is detached, when the number of puffs reaches a predetermined maximum number of puffs, when puffing is not sensed for a predetermined period of time or more, or when the remaining capacity of the battery 160 is less than a predetermined value.

[0065] The controller 170 can calculate the remaining capacity with respect to the full charge capacity of the battery 160. For example, the controller 170 can calculate the remaining capacity of the battery 160 based on values sensed by the voltage sensor and / or the current sensor included in the sensor module 150.

[0066] Figures 2A to 4 is a view for explaining an aerosol-generating device according to an embodiment of the disclosure.

[0067] According to various embodiments of the disclosure, the aerosol-generating device 100 can include a main body and / or a cartridge.

[0068] Referring to Figure 2A According to an embodiment, the aerosol-generating device 100 can include a main body 210 formed such that the cigarette 201 is insertable into an internal space formed by a housing 215.

[0069] The cigarette 201 can be similar to a general combustible cigarette. For example, the cigarette 201 can be divided into a first portion including an aerosol-generating material and a second portion including a filter. Alternatively, the second portion of the cigarette 201 can also include an aerosol-generating material. For example, a granular or capsule flavoring material can be inserted into the second portion.

[0070] The entire first portion can be inserted into the aerosol-generating device 100. The second portion can be exposed to the outside. Alternatively, only a portion of the first portion can be inserted into the aerosol-generating device 100. Alternatively, the entire first portion and a portion of the second portion can be inserted into the aerosol-generating device 100. The user can inhale the aerosol in a state in which the second portion is held in the mouth. At this time, as external air passes through the first portion, the aerosol can be generated. The generated aerosol can pass through the second portion to be introduced into the user's mouth.

[0071] The main body 210 can be configured such that external air is introduced into the main body 210 in a state in which the cigarette 201 is inserted therein. In this case, the external air introduced into the main body 210 can flow to the user's mouth via the cigarette 201.

[0072] When the cigarette 201 is inserted, the controller 170 can perform control such that power is supplied to the heater based on a temperature profile stored in the memory 140.

[0073] The heater can be disposed in the main body 210 at a position corresponding to a position at which the cigarette 201 is inserted into the main body 210. Although the heater is illustrated as a conductive heater 220 including a needle-shaped conductive track in the drawings, the disclosure is not limited thereto.

[0074] The heater can heat the inside and / or outside of the cigarette 201 using power supplied from the battery 160. An aerosol can be generated from the heated cigarette 201. At this time, the user can hold one end of the cigarette 201 in the mouth to inhale the aerosol containing the tobacco material.

[0075] Further, the controller 170 can perform control according to a predetermined condition so that power is supplied to the heater in a state in which the cigarette 201 is not inserted into the main body. For example, when a cleaning function for cleaning a space into which the cigarette 201 is inserted is selected in response to a command input by the user through the input / output interface 120, the controller 170 can perform control so that a predetermined amount of power is supplied to the heater.

[0076] The controller 170 can monitor the number of puffs based on a value sensed by the puff sensor from a point in time at which the cigarette 201 is inserted into the main body.

[0077] When the cigarette 201 is removed from the main body, the controller 170 can initialize the current number of puffs stored in the memory 140.

[0078] Referring to Figure 2B , the cigarette 201 according to an embodiment can include a tobacco rod 202 and a filter rod 203. The first portion described above with reference to Figure 2A may include the tobacco rod 202. The second portion described above with reference to Figure 2A may include the filter rod 203.

[0079] Although Figure 2B is shown as being composed of a single segment, the disclosure is not limited thereto. In other words, the filter rod 203 can be composed of a plurality of segments. For example, the filter rod 203 can include a first segment configured to cool an aerosol and a second segment configured to remove a predetermined component included in the aerosol. In addition, the filter rod 203 can further include at least one segment configured to perform other functions, as needed.

[0080] The cigarette 201 can be wrapped using at least one wrapper 205. At least one hole can be formed in the wrapper 205 to allow external air to be introduced thereinto or to allow internal gas to be discharged therefrom. In one example, the cigarette 201 can be wrapped using one wrapper 205. In another example, the cigarette 201 can be double-wrapped using two or more wrappers 205. For example, the tobacco rod 202 can be wrapped using a first wrapper. For example, the filter rod 203 can be wrapped using a second wrapper. The tobacco rod 202 and the filter rod 203, which are individually wrapped using separate wrappers, can be coupled to each other. The entire cigarette 201 can be wrapped using a third wrapper. When each of the tobacco rod 202 and the filter rod 203 is composed of a plurality of segments, the segments can be wrapped using separate wrappers. The entire cigarette 201 formed by coupling the segments, each of which is wrapped using a separate wrapper, to each other can be wrapped using another wrapper.

[0081] The tobacco rod 202 can include an aerosol generating material. For example, the aerosol generating material can include at least one of glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, or oleyl alcohol, but the present disclosure is not limited thereto. In addition, the tobacco rod 202 can include other additives, such as a flavoring agent, a wetting agent, and / or an organic acid. In addition, a flavoring liquid such as menthol or a humectant can be injected and added to the tobacco rod 202.

[0082] The tobacco rod 202 can be manufactured in various forms. For example, the tobacco rod 202 can be formed into a sheet or a strand. For example, the tobacco rod 202 can be formed into tobacco shreds formed by cutting a tobacco sheet into small pieces. For example, the tobacco rod 202 can be surrounded by a heat-conductive material. For example, the heat-conductive material can be a metal foil such as an aluminum foil, but the present disclosure is not limited thereto. In one example, the heat-conductive material surrounding the tobacco rod 202 can uniformly distribute heat transferred to the tobacco rod 202, thereby improving the conduction of heat applied to the tobacco rod. This can improve the taste of the tobacco. The heat-conductive material surrounding the tobacco rod 202 can function as a susceptor heated by an induction heater. Here, although not shown in the drawings, the tobacco rod 202 can include an additional susceptor in addition to the heat-conductive material surrounding the tobacco rod 202.

[0083] The filter rod 203 can be a cellulose acetate filter. The filter rod 203 can be formed into any one of various shapes. For example, the filter rod 203 can be a cylindrical rod. For example, the filter rod 203 can be a hollow tube type rod. For example, the filter rod 203 can be a recessed type rod. When the filter rod 203 is composed of a plurality of segments, at least one of the plurality of segments can be formed into a different shape.

[0084] The filter rod 203 can be formed to generate a flavor. In one example, a flavoring liquid can be injected into the filter rod 203. In one example, a separate fiber coated with a flavoring liquid can be inserted into the filter rod 203.

[0085] In addition, the filter rod 203 can include at least one capsule 204. Here, the capsule 204 can be used to generate a flavor. The capsule 204 can be used to generate an aerosol. For example, the capsule 204 can have a structure in which a film containing a flavoring material is wrapped. The capsule 204 can have a spherical or cylindrical shape, but the present disclosure is not limited thereto.

[0086] When the filter rod 203 includes a segment configured to cool an aerosol, the cooling segment can be made of a polymer material or a biodegradable polymer material. For example, the cooling segment can be made of only pure polylactic acid, but the present disclosure is not limited thereto. Alternatively, the cooling segment can be formed as a cellulose acetate filter in which a plurality of holes are formed. However, the cooling segment is not limited to the above-described examples, and any other type of cooling segment can be used as long as it is capable of cooling an aerosol.

[0087] AlthoughFigure 2B The cigarette 201 according to the embodiment can further include a front end filter, which is not shown. The front end filter can be located at a side of the tobacco rod 202 facing the filter rod 203. The front end filter can prevent the tobacco rod 202 from being separated outward. The front end filter can prevent the liquefied aerosol from flowing into the aerosol-generating device 100 from the tobacco rod 202 during inhalation by the user.

[0088] Referring to Figure 3 The aerosol-generating device 100 according to the embodiment can include a main body 310 and a cartridge 320. The main body 310 can support the cartridge 320, and the cartridge 320 can contain an aerosol-generating material.

[0089] According to one embodiment, the cartridge 320 can be configured to be detachably mounted to the main body 310. According to another embodiment, the cartridge 320 can be integrally formed with the main body 310. For example, the cartridge 320 can be mounted to the main body 310 such that at least a portion of the cartridge 320 is inserted into an internal space formed by a housing 315 of the main body 310.

[0090] The main body 310 can be formed to have a structure in which external air can be introduced into the main body 310 in a state in which the cartridge 320 is inserted therein. Here, the external air introduced into the main body 310 can flow into the user's mouth via the cartridge 320.

[0091] The controller 170 can determine whether the cartridge 320 is in a mounted state or a detached state using a cartridge detection sensor included in the sensor module 150. For example, the cartridge detection sensor can transmit a pulse current through a terminal connected to the cartridge 320. In this case, the cartridge detection sensor can determine whether the cartridge 320 is in a connected state based on whether the pulse current is received through another terminal.

[0092] The cartridge 320 can include a reservoir 321 configured to accommodate an aerosol-generating material and / or a heater 323 configured to heat the aerosol-generating material in the reservoir 321. For example, a liquid delivery element impregnated with (containing) the aerosol-generating material can be disposed inside the reservoir 321.
