Description

Technical Field

[0001] The embodiments relate to a vibrator structure for generating aerosols, and a smoke cartridge and aerosol generating apparatus including the vibrator structure. Background Technology

[0002] Recently, there has been an increasing demand for aerosol generating devices based on non-combustion methods that do not involve burning tobacco. For example, aerosol generating devices can deliver aerosols to the user's end airway by generating aerosols using non-combustion methods or by generating aerosols from aerosol generating substances and passing the aerosols through a flavor medium before they are output from the aerosol generating device.

[0003] The aerosol generating substance used in the aerosol generating device can be a flowing liquid, a gel, or a solid, such as a cigarette. The aerosol generating device can be used by supplying the aerosol generating substance to an internal aerosol generating substance reservoir, or it can be used in conjunction with a cartridge containing the aerosol generating substance. When the aerosol generating substance is depleted, the aerosol generating device can be used again by refilling the aerosol generating substance reservoir or replacing the cartridge with a new cartridge. Summary of the Invention

[0004] The problem the invention aims to solve

[0005] The implementation involves assembling and disassembling the vibrator structure, and simplifying the wiring for applying electrical power to the vibrator by modularly vibrating aerosol-generating substances to generate aerosols.

[0056] In the following, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0057] Figure 1 This is a block diagram of an aerosol generating apparatus according to one embodiment.

[0058] Reference Figure 1 The aerosol generating device 10000 may include a battery 11, an atomizer 12, a sensor 13, a user interface 14, a memory 15, and a processor 16. However, the aerosol generating device 10000 is not limited to... Figure 1 The illustrated embodiment. Based on the design of the aerosol generating apparatus 10000, those skilled in the art will understand that [the following can be omitted]. Figure 1 Some of the hardware components shown are shown, or other components may be added.

[0059] For example, the aerosol generating apparatus 10000 may include a main body, in which case the hardware components of the aerosol generating apparatus 10000 are located in the main body.

[0060] In another embodiment, the aerosol generating device 10000 may include a main body and a cartridge, and the hardware components in the aerosol generating device 10000 may be partitioned and located in the main body and the cartridge. Alternatively or additionally, at least some of the hardware components in the aerosol generating device 10000 may be located in each of the main body and the cartridge.

[0061] The operation of each component is described below, and there are no space restrictions on each component in the aerosol generating device 10000.

[0062] Battery 11 provides the power required for the aerosol generator 10000 to operate. That is, battery 11 powers the atomizer 12 to atomize the aerosol-generating material. Furthermore, battery 11 powers other hardware components in the aerosol generator 10000, namely sensor 13, user interface 14, memory 15, and processor 16. Battery 11 can be a rechargeable battery or a disposable battery.

[0063] For example, battery 11 may include a nickel-based battery (e.g., a nickel-metal hydride battery, a nickel-cadmium battery) or a lithium-based battery (e.g., a lithium-cobalt battery, a lithium phosphate battery, a lithium titanate battery, a lithium-ion battery, or a lithium polymer battery). However, the type of battery 11 used in the aerosol generating device 10000 is not limited to this. For example, battery 11 may also include an alkaline battery or a manganese battery.

[0064] The atomizer 12 receives power from the battery 11 under the control of the processor 16. The atomizer 12 can receive power from the battery 11 to atomize the aerosol generating substances stored in the aerosol generating device 10000.

[0065] The atomizer 12 may be located in the main body of the aerosol generating device 10000. Alternatively, when the aerosol generating device 10000 includes a main body and a cartridge, the atomizer 12 may be located in one of the cartridge and the main body, or may extend from the main body to the cartridge, or vice versa.

[0066] When the atomizer 12 is located in the cartridge, the atomizer 12 can receive power from the battery 11 located in at least one of the main body and the cartridge. Furthermore, when the atomizer 12 is split and located in both the main body and the cartridge, the power-requiring components of the atomizer 12 can receive power from the battery 11 located in at least one of the main body and the cartridge.

[0067] Atomizer 12 generates an aerosol from aerosol-generating material within the cartridge. An aerosol can refer to a suspension of liquid and / or solid particles dispersed in a gas. That is, the aerosol generated by atomizer 12 can be in a state where vaporized particles generated from the aerosol-generating material are mixed with air. For example, atomizer 12 can convert the phase of the aerosol-generating material into a gaseous phase through evaporation and / or sublimation. Atomizer 12 can also generate aerosols by finely ejecting aerosol-generating material in a liquid and / or solid phase.

[0068] For example, atomizer 12 can generate aerosols from aerosol-generating substances using an ultrasonic vibration method. The ultrasonic vibration method can refer to a method of generating aerosols by using ultrasonic waves generated by a vibrator to atomize the aerosol-generating substances.

[0069] Although not in Figure 1 As shown, the atomizer 12 may include a heater capable of heating the aerosol-generating material by generating heat. The aerosol-generating material can be heated by the heater to generate an aerosol.

[0070] The heater can be made of any suitable resistive material. For example, suitable resistive materials can be metals or metal alloys, including, but not limited to, titanium, zirconium, tantalum, platinum, nickel, cobalt, chromium, hafnium, niobium, molybdenum, tungsten, tin, gallium, manganese, iron, copper, stainless steel, nickel-chromium, etc. Furthermore, the heater can be made of metal heating wires, metal heating plates with conductive tracks, ceramic heating elements, etc., but is not limited to these.

[0071] For example, in one embodiment, the heater may be part of the cartridge 2000. Furthermore, the cartridge 2000 may include a liquid delivery unit and a liquid storage unit, which will be described later. Aerosol-generating material contained in the liquid storage unit is moved to the liquid delivery unit, and the heater may heat the aerosol-generating material absorbed by the liquid delivery unit to generate an aerosol. For example, the heater may be wrapped around or positioned near the liquid delivery unit.

[0072] In another embodiment, the aerosol generating apparatus 10000 may include a receiving space capable of accommodating cigarettes, and a heater capable of heating cigarettes inserted into the receiving space of the aerosol generating apparatus 10000. Since the cigarettes are contained within the receiving space of the aerosol generating apparatus 10000, the heater may be located inside and / or outside the cigarettes. Therefore, the heater can heat the aerosol-generating substances in the cigarettes to generate aerosols.

[0073] On the other hand, the heater can be an induction heating type heater. The heater may include a conductive coil for heating the cigarette or cartridge in an induction heating manner, and the cigarette or cartridge may include a heat-sensitive element that can be heated by the induction heating type heater.

[0074] The aerosol generating device 10000 may include at least one sensor 13. The results sensed by the at least one sensor 13 may be transmitted to a processor 16, and based on the sensing results, the processor 16 may control the aerosol generating device 10000 to perform various functions, such as operation control of the atomizer 12, smoking restriction, determination of whether a cartridge (or cigarette) is inserted, display of notifications, etc.

[0075] For example, at least one sensor 13 may include a suction detection sensor. The suction detection sensor may detect the user's suction based on at least one of changes in the velocity of an externally introduced airflow, changes in pressure, and sound detection. The suction detection sensor may detect the start and end times of the user's suction, and the processor 16 may determine the suction cycle and non-suction cycle based on the detected start and end times of the suction.

[0076] Furthermore, at least one sensor 13 may include a user input sensor. The user input sensor may be a sensor capable of receiving user input, such as a switch, physical button, or touch sensor. For example, when a user touches a predetermined area formed of a metallic material, the capacitance changes, and the touch sensor may be a capacitive sensor capable of detecting user input by detecting the capacitance change. The processor 16 can determine whether user input has occurred by comparing the values ​​received from the capacitive sensor before and after the capacitance change. When the values ​​before and after the capacitance change exceed a preset threshold, the processor 16 can determine that user input has occurred.

[0077] Furthermore, at least one sensor 13 may include a motion sensor. Information regarding the motion of the aerosol generating device 10000 can be acquired via the motion sensor, such as the tilt angle, moving speed, and acceleration of the aerosol generating device 10000. For example, the motion sensor can measure information regarding the moving state of the aerosol generating device 10000, the stationary state of the aerosol generating device 10000, the state in which the aerosol generating device 10000 is tilted at an angle within a predetermined range for suction, and the angle of the aerosol generating device 10000 between each suction motion. The motion sensor can measure the motion information of the aerosol generating device 10000 using various methods. For example, the motion sensor may include an accelerometer capable of measuring acceleration in three directions (x-axis, y-axis, and z-axis), and a gyroscope sensor capable of measuring angular velocity in three directions.

[0078] Furthermore, at least one sensor 13 may include a proximity sensor. A proximity sensor is a sensor that detects the presence or distance of an approaching object or a nearby object without mechanical contact and without using forces such as electromagnetic fields or infrared radiation. The proximity sensor can detect whether a user is approaching the aerosol generating device 10000.

[0079] Furthermore, at least one sensor 13 may include an image sensor. For example, the image sensor may include a camera for acquiring images of objects. The image sensor can identify objects based on images acquired by the camera. The processor 16 can analyze the images acquired by the image sensor to determine whether a user is using the aerosol generating device 10000. For example, when a user approaches the aerosol generating device 10000 near their lips to use the aerosol generating device 10000, the image sensor can acquire an image of lips. The processor 16 can analyze the acquired image, and when the acquired image is identified as lips, it determines that the user is using the aerosol generating device 10000. Based on this determination, the aerosol generating device 10000 can pre-activate the atomizer 12 or preheat the heater.

[0080] Furthermore, at least one sensor 13 may include a consumable separation sensor capable of detecting the installation or removal of consumables (e.g., cartridges, cigarettes, etc.) that can be used in the aerosol generating device 10000. For example, the consumable separation sensor may detect whether the consumable has come into contact with the aerosol generating device 10000, or it may determine whether the consumable has been separated by an image sensor. Alternatively, the consumable separation sensor may be an inductive sensor that detects changes in the inductance of a coil that can interact with a consumable marker, or it may be a capacitive sensor that detects changes in the capacitance of a capacitor that can interact with a consumable marker.

[0081] In addition, at least one sensor 13 may include a temperature sensor. The temperature sensor can sense the temperature at which the heater (or aerosol generating material) of the atomizer 12 is heated. The aerosol generating device 10000 may include a temperature sensor for sensing the temperature of the heater, or the heater itself may serve as a temperature sensor. Optionally or additionally, when the heater itself serves as a temperature sensor, a separate temperature sensor may also be included in the aerosol generating device 10000. Furthermore, the temperature sensor can sense the temperature of internal components, such as a printed circuit board (PCB) and the battery and heater of the aerosol generating device 10000.

[0082] Furthermore, at least one sensor 13 may include various sensors that measure information about the environment surrounding the aerosol generating device 10000. For example, at least one sensor 13 may include a temperature sensor that measures the ambient temperature, a humidity sensor that measures the ambient humidity, and an atmospheric pressure sensor that measures the ambient pressure.

[0083] The sensors 13 provided in the aerosol generating apparatus 10000 are not limited to the types described above, and may also include various other sensors. For example, the aerosol generating apparatus 10000 may include: a fingerprint sensor capable of acquiring fingerprint information from a user's finger for user authentication and security; an iris recognition sensor for analyzing the iris pattern of the pupil; a vein recognition sensor that detects the amount of infrared absorption of reduced hemoglobin in veins from an image of the palm; a face recognition sensor that identifies feature points such as eyes, nose, mouth, and facial contours in a 2D or 3D manner; and a radio frequency identification (RFID) sensor.

[0084] In the aerosol generating apparatus 10000, only one or some embodiments of the various sensors 13 provided above can be selected and implemented. In other words, the aerosol generating apparatus 10000 can combine and utilize information sensed by at least one of the sensors described above.

[0085] User interface 14 can provide users with information about the status of aerosol generating device 10000. User interface 14 may include various interface devices, such as a display or light for outputting visual information, a motor for outputting tactile information, a speaker for outputting sound information, terminals for data communication with input / output (I / O) interface devices (e.g., buttons or touch screens) that receive information input from or output information to the user, or for receiving charging power, and communication interface modules for performing wireless communication with external devices (e.g., Wi-Fi, Wi-Fi Direct, Bluetooth, Near Field Communication (NFC), etc.).

[0086] However, in the aerosol generating apparatus 10000, only one or some of the various user interface embodiments 14 provided above can be selected and implemented.

[0087] The memory 15 is hardware used to store various data processed in the aerosol generating apparatus 10000, and can store data processed by the processor 16 and data to be processed. The memory 15 can be implemented in various types, such as random access memory (RAM) including dynamic random access memory (DRAM) and static random access memory (SRAM), read-only memory (ROM) and electrically erasable programmable read-only memory (EEPROM).

[0088] The memory 15 can store the operating time of the aerosol generating device 10000, the maximum number of puffs, the current number of puffs, at least one temperature profile, and data about the user's smoking pattern.

[0089] Processor 16 controls the overall operation of aerosol generation device 10000. Processor 16 can be implemented as an array of multiple logic gates, or as a combination of a general-purpose microprocessor and a memory storing microprocessor-executable programs. Furthermore, those skilled in the art will understand that processor 16 can be implemented using other types of hardware.

[0090] The processor 16 analyzes the results sensed by at least one sensor 13 and controls the subsequent processing to be performed.

[0091] The processor 16 can control the power supply to the atomizer 12 based on the results sensed by at least one sensor 13, to start or stop the operation of the atomizer 12. Furthermore, the processor 16 can control the amount of electricity supplied to the atomizer 12 and the duration of power supply so that the atomizer 12 can generate an appropriate amount of aerosol based on the results sensed by at least one sensor 13. For example, the processor 16 can control the electrical energy (e.g., current or voltage) supplied to the vibrator, causing the vibrator of the atomizer 12 to vibrate at a predetermined frequency.

[0092] In one embodiment, the processor 16 can start operating the atomizer 12 after receiving user input from the aerosol generating device 10000. Furthermore, the processor 16 can start operating the atomizer 12 after detecting the user's inhalation using a vaping detection sensor. Additionally, after calculating the number of inhalations using the vaping detection sensor, the processor 16 can stop supplying power to the atomizer 12 when the number of inhalations reaches a preset number.

[0093] The processor 16 can control the user interface 14 based on the results sensed by at least one sensor 13. For example, after calculating the number of aspirations using a suction detection sensor, when the number of aspirations reaches a preset number, the processor 16 can use at least one of a light, a motor, and a speaker to notify the user that the aerosol generating device 10000 will soon terminate.

[0094] On the other hand, although not in Figure 1 As shown, the aerosol generating device 10000 may be included in the aerosol generating system along with a separate bracket. For example, the bracket may be used to charge the battery 11 of the aerosol generating device 10000. For example, the aerosol generating device 10000 may receive power from the battery in the bracket and charge the battery 11 of the aerosol generating device 10000 when housed in the receiving space within the bracket.

[0095] One or more embodiments may also be implemented in the form of a recording medium, which includes computer-executable instructions, such as computer-executable program modules. Computer-readable media can be any available medium accessible to a computer, and includes volatile and non-volatile media, as well as removable and non-removable media. Furthermore, computer-readable media can include computer storage media and communication media. Computer memory includes volatile and non-volatile media, as well as removable and non-removable media implemented in any method or technology, for storing information, such as computer-readable instructions, data structures, program modules, or other data. Communication media can include computer-readable instructions, data structures, other data in non-transient data signals, such as program modules.

[0096] Figure 2 This is a schematic diagram illustrating an aerosol generating apparatus according to one embodiment.

[0097] according to Figure 2 The aerosol generating apparatus 10000 of the illustrated embodiment includes a cartridge 2000 containing an aerosol generating substance and a main body 1000 supporting the cartridge 2000.

[0098] The cartridge 2000 can be bonded to the body 1000 while containing an aerosol-generating substance. For example, a portion of the cartridge 2000 can be inserted into the body 1000, or a portion of the body 1000 can be inserted into the cartridge 2000, allowing the cartridge 2000 to be mounted on the body 1000. In this case, the body 1000 can be held together with the cartridge 2000 by means of snap-fit, screw connection, magnetic connection, interference fit, etc., but the method of bonding the body 1000 and the cartridge 2000 is not limited to the above description.

[0099] The cartridge 2000 may include a mouthpiece 2100. The mouthpiece 2100 may be formed on the side opposite to the portion attached to the body 1000 and may be a portion inserted into the user's mouth. The mouthpiece 2100 may include a discharge port 2110 for discharging aerosols generated from aerosol-generating substances inside the cartridge 2000 to the outside.

[0100] The cartridge 2000 can contain an aerosol-generating substance in any state, such as liquid, solid, gas, or gel. The aerosol-generating substance may include a liquid composition. For example, the liquid composition may be a liquid containing tobacco substances (including volatile tobacco aroma components), or it may be a liquid containing non-tobacco substances.

[0101] For example, the liquid composition may include any or a mixture of water, solvent, ethanol, plant extracts, fragrances, flavorings, and vitamin mixtures. Fragrances may include, but are not limited to, menthol, peppermint oil, various fruit flavoring ingredients, etc. Flavorings may include ingredients capable of providing a variety of flavors to the user. Vitamin mixtures may be, but are not limited to, a mixture of at least one of vitamins A, B, C, and E. Furthermore, the liquid composition may include aerosol forming agents, such as glycerin and propylene glycol.

[0102] For example, the liquid composition may comprise any weight ratio of glycerol and propylene glycol solution with added nicotine salts. The liquid composition may comprise two or more types of nicotine salts. Nicotine salts can be formed by adding acids, including organic or inorganic acids, to nicotine. The nicotine may be naturally occurring or synthetic nicotine and may have any weight concentration relative to the total solution weight of the liquid composition.

[0103] Considering factors such as blood nicotine absorption rate, operating temperature of the aerosol generating device 10000, aroma or flavor, and solubility, the acid used to form nicotine salts can be appropriately selected. For example, the acid used to form nicotine salts can be selected from benzoic acid, lactic acid, salicylic acid, lauric acid, sorbic acid, levulinic acid, pyruvic acid, formic acid, acetic acid, propionic acid, butyric acid, valeric acid, hexanoic acid, caprylic acid, capric acid, citric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, phenylacetic acid, tartaric acid, succinic acid, fumaric acid, gluconic acid, sucralose, malonic acid, or malic acid, or a mixture of two or more acids selected from this group, but is not limited thereto.

[0104] The cartridge 2000 may include a liquid storage unit 2200 for containing aerosol-generating material therein. The liquid storage unit 2200 containing aerosol-generating material may mean that the liquid storage unit 2200 performs a function including aerosol-generating material (e.g., a container), and the liquid storage unit 2200 may include an element impregnated with (or containing) aerosol-generating material, such as a sponge, cotton or cloth, or a porous ceramic structure.

[0105] The aerosol generating device 10000 may include an atomizer that performs a phase inversion of aerosol-generating substances within the cartridge 2000 to generate an aerosol.

[0106] For example, the atomizer of the aerosol generating device 10000 can convert the phase of the aerosol generating material by using ultrasonic vibration to atomize the aerosol generating material. The atomizer may include a vibrator 1300 that generates ultrasonic vibrations, a liquid transport unit 2400 that absorbs the aerosol generating material and maintains the absorbed aerosol generating material in an optimal state for conversion into an aerosol, and a vibration receiving unit 2300 for generating aerosols by transmitting ultrasonic vibrations to the aerosol generating material in the liquid transport unit.

[0107] The vibrator 1300 can generate short-period vibrations. The vibrations generated by the vibrator 1300 can be ultrasonic vibrations, and the frequency of the ultrasonic vibrations can be, for example, from 100 kHz to 3.5 MHz. Through the short-period vibrations generated from the vibrator 1300, aerosol-generating substances can evaporate and / or atomize into aerosols.

[0108] For example, vibrator 1300 may include piezoelectric ceramic, a functional material that can convert electricity into mechanical force by generating electricity (voltage) through physical force (pressure) and generating vibration (mechanical force) when electricity is applied. Therefore, vibration (physical force) is generated by electricity applied to vibrator 1300, and this small physical vibration can break down aerosol-generating material into small particles and atomize the aerosol-generating material into aerosols.

[0109] The vibrator 1300 can be electrically connected to a circuit via a spring pin or a C-clamp. Therefore, the vibrator 1300 can generate vibration by receiving current or voltage from the spring pin or C-clamp. However, the types of components connected to the vibrator 1300 to provide current or voltage are not limited to those described above.

[0110] The vibration receiving unit 2300 can receive vibrations generated by the vibrator 1300 and convert aerosol-generating substances transmitted from the liquid storage unit 2200 into aerosols.

[0111] The liquid transport unit 2400 can transport the liquid composition of the liquid storage unit 2200 to the vibration receiving unit 2300. For example, the liquid transport unit 2400 may be a core, including, but not limited to, at least one of cotton fiber, ceramic fiber, glass fiber and porous ceramic.

[0112] The atomizer can also be implemented as a mesh or plate-shaped vibration containment unit, which has the function of absorbing aerosol generating substances and keeping them in an optimal state for conversion into aerosols without using a separate liquid delivery device, and also has the function of generating aerosols by transmitting vibrations to the aerosol generating substances.

[0113] In addition, Figure 2 In the illustrated embodiment, the vibrator 1300 of the atomizer is disposed in the main body 1000, and the vibration receiving unit 2300 and the liquid transmission unit 2400 are disposed in the cartridge 2000, but the embodiment is not limited thereto. For example, the cartridge 2000 may include the vibrator 1300, the vibration receiving unit 2300, and the liquid transmission unit 2400. When a portion of the cartridge 2000 is inserted into the main body 1000, the main body 1000 may supply power to the cartridge 2000 through a terminal (not shown), or provide the cartridge 2000 with signals related to the operation of the cartridge 2000, thereby controlling the operation of the vibrator 1300.

[0114] The liquid storage unit 2200 of the cartridge 2000 may include at least a portion of a transparent material so that the aerosol-generating substances contained in the cartridge 2000 can be seen from the outside. The mouthpiece 2100 and the liquid storage unit 2200 may be made entirely of transparent plastic or glass, and only a portion of the liquid storage unit 2200 may be made of a transparent material.

[0115] The smoke cartridge 2000 of the aerosol generating device 10000 may include an aerosol emission channel 2500 and an airflow channel 2600.

[0116] The aerosol emission channel 2500 can be formed in the liquid storage unit 2200 to be in fluid communication with the emission port 2110 of the mouthpiece 2100. Therefore, the aerosol generated by the atomizer can move along the aerosol emission channel 2500 and can be delivered to the user through the emission port 2110 of the mouthpiece 2100.

[0117] The airflow channel 2600 is a channel for introducing external air into the aerosol generating device 10000. The external air introduced through the airflow channel 2600 can be introduced into the aerosol emission channel 2500 or into the space where aerosols are generated. Therefore, the introduced external air can mix with vaporized particles generated from the aerosol generating material to generate aerosols.

[0118] For example, such as Figure 2 As shown, the airflow channel 2600 can be formed around the exterior of the aerosol emission channel 2500. Therefore, the aerosol emission channel 2500 and the airflow channel 2600 can be a dual-tube type, with the aerosol emission channel 2500 located inside and the airflow channel 2600 located outside. Thus, external air can be introduced in the opposite direction to the direction in which the aerosol moves within the aerosol emission channel 2500.

[0119] However, the structure of the airflow channel 2600 is not limited to the above description. For example, the airflow channel may be the space formed between the main body 1000 and the cartridge 2000 when the main body 1000 and the cartridge 2000 are combined and in fluid communication with the atomizer.

[0120] In the aerosol generating device 10000 according to the above embodiment, the cross-sectional shape in the direction transverse to the longitudinal direction of the main body 1000 and the cartridge 2000 can be approximately circular, elliptical, square, rectangular, or a polygonal cross-sectional shape of various shapes. However, the cross-sectional shape of the aerosol generating device 10000 is not limited to the above description, and the aerosol generating device 10000 is not necessarily limited to a structure that extends in a straight line when extending longitudinally. For example, the cross-sectional shape of the aerosol generating device 10000 can be bent into a streamlined shape so that the user can easily hold it in their hand, or it can be bent and extended at a predetermined angle in a specific area, and the cross-sectional shape of the aerosol generating device 10000 can vary longitudinally.

[0121] Figure 3A This is an exploded perspective view of a vibrator structure according to one embodiment. Figure 3B yes Figure 3A A cross-sectional view of the vibrator structure.

[0122] Reference Figure 3A and 3BAccording to one embodiment, the vibrator structure 10 may include a vibrator 100, a first electrode 111, a second electrode 121, and a metal body 200, and may also include a lower electrode 300. The vibrator structure 10 may be included in a cartridge or body to atomize aerosol-generating substances transported from outside the vibrator structure 10.

[0123] The vibrator 100 vibrates according to the applied electrical energy. For example, the vibrator 100 can receive electrical energy through a second surface 120 opposite to the first surface 110. The vibrator 100 can vibrate with a specific intensity, a specific frequency, and a specific mode based on at least one of the intensity, frequency, and direction of the applied electrical energy.

[0124] The vibrator 100 may be plate-shaped. For example, the vibrator 100 may be disc-shaped or square plate-shaped, but is not limited to these, and may also be cylindrical.

[0125] The first electrode 111 can be disposed on the first surface 110 of the vibrator 100, and the second electrode 121 can be disposed on the second surface 120 of the vibrator 100. For example, when the vibrator 100 has a disk shape, the first surface 110 can be the upper surface, and the second surface 120 can be the lower surface.

[0126] By placing the first electrode 111 and the second electrode 121 on opposite sides of the vibrator 100, an electric field can be formed in the vibrator 100 when electrical energy is applied, in a direction perpendicular to the first surface 110 and the second surface 120 of the vibrator 100. Therefore, the vibration direction of the vibrator 100 can be perpendicular to the first surface 110 and the second surface 120.

[0127] For example, the vibration direction of the vibrator 100 can be perpendicular to the first surface 110 and the second surface 120. However, the vibration direction of the vibrator 100 is not limited to this, and depending on the shape of the vibrator 100, the vibrator 100 can vibrate in a direction that is horizontal to the first surface 110 and the second surface 120.

[0128] The first electrode 111 and the second electrode 121 can be made of a material with high conductivity. For example, the first electrode 111 and the second electrode 121 can be formed of any one of silver (Ag), copper (Cu), gold (Au), aluminum (Al), tungsten (W), iron (Fe), platinum (Pt), and lead (Pb). For example, the first electrode 111 and the second electrode 121 can be formed by coating silver paste onto the first surface 110 and the second surface 120 of the vibrator 100, respectively.

[0129] According to one embodiment, the first electrode 111 and the second electrode 121 may be disposed on at least one region of the first surface 110 and at least one region of the second surface 120, respectively. For example, the first electrode 111 may be disposed on the entire region of the first surface 110.

[0130] As another embodiment, the first electrode 111 may be disposed over the entire area except for at least one region of the first surface 110. For example, the first electrode 111 may be formed from silver paste applied to the entire area except for at least a portion of the edge of the first surface 110.

[0131] According to another embodiment, the first electrode 111 may be disposed along the edge of the first surface 100. For example, the first electrode 111 may be disposed on the entire edge of the first surface 110. As another embodiment, the first electrode 111 may be disposed on a portion of the edge of the first surface 110. Here, the first electrode 111 being disposed along the edge of the first surface 100 may mean not only that the first electrode 111 is disposed on the edge of the first surface 110, but also that the first electrode 111 is disposed over a wider area including the edge.

[0132] The second electrode 121 may be disposed at a position spaced apart from the edge of the second surface 120 in the direction toward the center. For example, the second electrode 121 may be located at the center of the second surface 120 of the vibrator 100. As another embodiment, the second electrode 121 may be disposed in a circular strip at a position spaced at a predetermined distance from the center of the vibrator 100. Here, "the second electrode 121 is disposed at a position spaced apart from the edge of the second surface 120 in the direction toward the center" may mean not only that the second electrode 121 is disposed at the center of the second surface 120, but also that the second electrode 121 is disposed over a wider area including the center.

[0133] The positions of the first electrode 111 and the second electrode 121 are not limited to the positions described above, and those skilled in the art to which this embodiment pertains will understand that other positions where electrodes can be formed on both surfaces of the vibrator 100 may also be included.

[0134] The metal body 200 may house the vibrator 100 and may contact at least one region of the first electrode 111 to transfer electrical energy applied from outside the vibrator structure 10 to or from the first electrode 111. For example, the metal body 200 may have a structure surrounding at least a portion of the vibrator 100 while exposing at least a portion of the vibrator 100 to the outside of the metal body 200.

[0135] According to one embodiment, the metal body 200 may include a sidewall 220 forming a cavity for accommodating the vibrator 100 and an upper electrode 210 in contact with the first electrode 111 of the vibrator 100. For example, the metal body 200 may have a cylindrical structure including the sidewall 220, and the upper electrode 210 may have a structure that protrudes from the sidewall 220 toward the center of the first surface 110.

[0136] In this case, the vibrator 100 can be inserted into the side wall 220 of the metal body 200, the first surface 110 of the vibrator 100 can contact the upper electrode 210 of the metal body 200, so that the vibrator 100 can be electrically connected to the metal body 200, and at least a portion of the first surface 110 of the vibrator 100 can be exposed to the outside of the metal body 200.

[0137] According to another embodiment, the metal body 200 can be a cylindrical cap structure. Here, an upper electrode 210 can be formed on the upper surface of the cap, and a sidewall 220 can be formed on the sidewall of the cap. The vibrator 100 can be inserted into the metal body 200 such that the first electrode 111 of the vibrator 100 and the upper electrode 210 of the metal body 200 are in contact with each other.

[0138] A through-hole 230 can be formed in the upper surface of the metal body 200, exposing the interior of the metal body 200, and the diameter of the through-hole 230 is smaller than the diameter of the cylindrical vibrator 100. The aerosol generated by the vibrator 100 can move to the outside of the vibrator structure through the through-hole 230.

[0139] The vibrator 100 can be joined by an interference fit between the outer peripheral surface of the vibrator 100 and the inner peripheral surface of the sidewall 220 of the metal body 200, or the adhesion between the vibrator 100 and the metal body 200 can be maintained by an adhesive material. Furthermore, the vibrator 100 can be joined to the metal body 200 along with other components described later to maintain the connection with the metal body 200.

[0140] The metal body 200 can be made of a conductive material. For example, the metal body 200 can be made of stainless steel or aluminum, but is not limited to these; other conductive materials can also be used to manufacture the metal body 200.

[0141] The lower electrode 300 can contact the second electrode 121 of the vibrator 100 to receive electrical energy applied from outside the vibrator structure 10 from the second electrode 121, or to transfer electrical energy to the second electrode 121. The lower electrode 300 can have, for example, a columnar structure. The lower electrode 300 can not only be electrically connected to the second electrode 121 of the vibrator 100, but can also support the vibrator 100 on the second surface 120 of the vibrator 100.

[0142] For example, the lower electrode 300 can have a structure in which the diameter varies with the height. This structure can facilitate the integration of the lower electrode 300 with other components. The lower electrode 300 can be made of a conductive material, such as gold, silver, copper, etc., or it can be made of the same material as the metal body 200.

[0143] According to the embodiment, in the upper electrode 210 and lower electrode 300 connected to the vibrator 100, the metal body 200 or the upper electrode 210 can be a positive electrode (+), and the lower electrode 300 can be a negative electrode (-). Conversely, the metal body 200 or the upper electrode 210 can be a negative electrode (-), and the lower electrode 300 can be a positive electrode (+).

[0144] As described above, the upper electrode 210, the vibrator 100, and the lower electrode 300 are part of a circuit and can be connected to an external power source that supplies power to the circuit.

[0145] According to one embodiment, the vibrator structure 10 can be modularized by including a vibrator 100, a metal body 200, or an upper electrode 210 electrically connected to a first electrode 111 and a lower electrode 300 electrically connected to a second electrode 121. Therefore, the vibrator 100 located within the metal body 200 not only has stability against external shocks, but also simplifies the wiring used to provide electrical power.

[0146] Figure 4A This is an exploded perspective view of a vibrator structure according to another embodiment. Figure 4B yes Figure 4A A cross-sectional view of the vibrator structure.

[0147] Reference Figure 4A and 4B According to another embodiment, the vibrator structure 10 may include a vibrator 100, a metal body 200, a first electrode 111, a second electrode 121, a lower electrode 300, elastic bodies 400 and 500, a pressure body 550, and a support body 600.

[0148] Figure 4A and 4B The vibrator structure 10 shown may include elastic bodies 400 and 500, a pressure body 550, and a support body 600 added thereto. Figure 3A and 3B The vibrator structure 10 in the vibrator structure 10, and in the following text Figure 3A and 3B The descriptions already given are omitted, and additional components are described in detail.

[0149] The metal body 200 in contact with the vibrator 100 can vibrate by receiving vibrations from the vibrator. As the metal body 200 vibrates together, the vibration efficiency of the vibrator 100 may decrease, and since the vibrator structure 10 vibrates as a whole, it may cause inconvenience to users of aerosol generating devices that include the vibrator structure 10. Therefore, a structural design may be needed to prevent or reduce the overall vibration of the vibrator structure 10.

[0150] The elastomer can be combined with the metal body 200 to receive vibrations from the vibrator 100 and absorb vibrations from the metal body 200. For example, the elastomer can be made of any of, but is not limited to, rubber, silicone, synthetic resin and porous materials, and can be made of any other material capable of absorbing or attenuating vibrations transmitted to the metal body 200.

[0151] According to one embodiment, the elastomer may include a first elastomer 400 bonded to the upper side of the metal body 200 and a second elastomer 500 bonded to the lower side of the metal body 200. For example, the first elastomer 400 may be configured to surround at least a portion of the outer surface of the metal body 200, and the second elastomer 500 may be configured to surround at least a portion of the inner surface of the metal body 200.

[0152] The first elastic body 400 can be coupled to the metal body 200 by interference fit or snap-fit, and the second elastic body 500 can also be coupled to the metal body 200 by interference fit or snap-fit. Therefore, the metal body 200, the first elastic body 400, and the second elastic body 500 can be coupled without separate fastening elements, thereby facilitating the disassembly and assembly of the vibrator structure 10.

[0153] The method of joining the elastomer and the metal body 200 is not limited to the above embodiments, and separate fastening elements, such as screws or keys, can be used.

[0154] According to one embodiment, the first elastomer 400 may include a hole portion 410 that exposes at least a portion of the first surface 110 of the vibrator 100 housed in the metal body 200 to the outside. The hole portion 410 may communicate with a discharge channel through which fluid in the aerosol generating device moves to the outside. Thus, aerosol generated by the vibrator 100 can move through the hole portion 410 to the outside of the vibrator structure 10, and further can move along the discharge channel to be discharged to the outside of the aerosol generating device.

[0155] The second elastic body 500 can contact at least a portion of the second surface 120 of the vibrator 100. For example, the vibrator 100 can be located between the upper electrode 210 of the metal body 200 and the second elastic body 500, and can be pressed by the second elastic body 500 in a direction from the lower electrode 300 toward the upper electrode 210. Therefore, the electrical contact between the vibrator 100 and the metal body 200 can be more robust, and the electrical energy flowing along the vibrator 100 and the metal body 200 can be transmitted more smoothly.

[0156] According to another embodiment, the metal body 200 is coaxially coupled to the first elastic body 400 and the second elastic body 500 in a direction parallel to the direction from the first surface 110 toward the second surface 120 of the vibrator 100. For example, the metal body 200, the first elastic body 400, and the second elastic body 500 can be manufactured to have the same cross-sectional shape when viewed from a direction perpendicular to the first surface 110 and the second surface 120 of the vibrator 100. Therefore, the metal body 200 can be coupled to the interior of the first elastic body 400, and the second elastic body 500 can be coupled to the interior of the metal body 200.

[0157] For example, the metal body 200, the first elastic body 400 and the second elastic body 500 may have a basic cylindrical shape and may be combined in such a way that three cylinders with different diameters are arranged on each other.

[0158] The pressure body 550 can contact at least a portion of the vibrator 100 and at least a portion of the lower electrode 300 to maintain contact between the vibrator 100 and the lower electrode 300. For example, the pressure body 550 can be made of rubber or silicone material and can be in close contact with at least a portion of the second surface 120 of the vibrator 100 or at least a portion of the second electrode 121, and can be in close contact with at least a portion of the outer surface of the lower electrode 300, so that the contact between the second electrode 121 and the lower electrode 300 can be firmly maintained by pressing the pressure body 550.

[0159] In one embodiment, the pressure body 550 may be located within a second elastic body 500 incorporated into the metal body 200 and may have a structure surrounding the lower electrode 300. In another embodiment, the pressure body 550 may be integrally formed with the second elastic body 500 and may have a structure surrounding the lower electrode 300.

[0160] In another embodiment, the pressurizing body 550 and the lower electrode 300 can be manufactured to interlock with each other. For example, as Figure 4B As shown, the lower electrode 300 and the pressure body 550 are manufactured with a stepped structure in cross-section, allowing them to be firmly bonded together. Therefore, the contact between the lower electrode 300 and the second electrode 121 can be easily separated.

[0161] The support 600 can support the metal body 200. For example, the support 600 can be located on the opposite side of the metal body 200 where the upper electrode 210 is located, in order to support the metal body 200. Specifically, the upper surface of the support 600 can contact the lower surface of the metal body 200 to provide a reaction force to the lower surface of the metal body 200.

[0162] The support 600 can support other components located within the metal body 200. For example, the support 600 can support a first elastic body 400 and / or a second elastic body 500 bonded to the metal body 200.

[0163] In one embodiment, the support 600 may be a structure surrounding at least a portion of the outer surface of the second elastic body 500 or at least a portion of the outer surface of the pressure body 550. In another embodiment, at least a portion of the outer surface of the support 600 may be a structure engaging with at least a portion of the outer surface of the second elastic body 500 and / or at least a portion of the outer surface of the pressure body 550, and the support 600 and the second elastic body 500 and / or the support 600 and the pressure body 550 may be coupled to each other in an interference fit manner.

[0164] The second elastic body 500 and the pressure body 550, which are attached to the support 600, are firmly attached to the metal body 200, so that the bond between the support 600 and the metal body 200 can also be firmly maintained. Furthermore, the pressure body 550 attached to the support 600 can maintain the bond between the lower electrode 300 and the vibrator 100. Therefore, a strong organic bond can be formed between the components in the vibrator structure 10.

[0165] According to one embodiment, the support 600 includes a conductive portion 610 connected to the metal body 200 and can support the metal body 200. For example, the conductive portion of the support 600 can be electrically connected to the metal body 200 at one end 221 of the sidewall 220 of the metal body 200.

[0166] In one embodiment, a portion of the support 600 may be made of an insulator (e.g., rubber, synthetic resin, plastic), while the remainder may be a conductive portion 610 made of a conductive material. In another embodiment, the support 600 may be made entirely of a conductive material and may perform the function of the conductive portion 610, supporting the metal body 200 and simultaneously transmitting electrical energy to the metal body 200.

[0167] One side of the conductive part 610 can be electrically connected to the metal body 200, and the other side opposite to one side can be electrically connected to an external power source of the vibrator structure 10. Specifically, one side of the conductive part 610 can be located on the upper surface of the support 600, and the other side of the conductive part 610 can be located on the lower surface of the support 600.

[0168] Since the support 600 includes a conductive part 610, electrical energy through the metal body 200 can be transmitted to the outside of the vibrator structure 10, or electrical energy applied from the outside of the vibrator structure 10 can be transmitted to the metal body 200.

[0169] According to one embodiment, the support 600 may further include a through-hole 620 that allows an external terminal for providing electrical power to be connected to the lower electrode. As one embodiment, such as Figure 4B As shown, the through hole 620 can be located at the center of the support 600, and one end of the lower electrode 300 can be located in the through hole 620.

[0170] In another embodiment, an external terminal can be inserted through the through-hole 620 so that the external terminal can be connected to the lower electrode 300. The external terminal may include at least one of, for example, a spring pin, a C-clamp, and an FPCB. When the external terminal is inserted into the through-hole 620, the external terminal and the lower electrode 300 are electrically connected to each other, so that electrical energy can be applied to the vibrator structure 10.

[0171] Therefore, the support 600 can be located at one end 221 of the metal body 200 to support the metal body 200 and the components within it. Furthermore, the vibrator structure 10 can be connected to an external power source and / or external terminals via the support 600. Thus, a circuit capable of transmitting electrical energy can be formed along the conductive portion 610 of the support 600, the metal body 200, the vibrator 100, the lower electrode 300, and the external terminals.

[0172] In the vibrator 100 connected to the support 600 and the lower electrode 300 in contact with the metal body 200, the support 600 or the conductive part 610 can be positive (+) and the lower electrode 300 can be negative (-). Alternatively, the support 600 or the conductive part 610 can be negative (-) and the lower electrode 300 can be positive (+).

[0173] Figure 5 This is a view used to describe the heat flow in the vibrator structure according to the embodiment.

[0174] Reference Figure 5 According to the embodiment, the vibrator structure 10 may include a vibrator 100, a first electrode 111, a second electrode 121, a metal body 200, a lower electrode 300, and a support body 600.

[0175] Figure 5 The vibrator structure 10 in the middle can be in which a support 600 is added Figure 3A and Figure 3B The vibrator structure 10 in the text, and in the following text Figure 3A and Figure 3BThe description already given has been omitted.

[0176] Depending on the material constituting the vibrator 100 or the material of the vibrator 100 itself, the inherent characteristics of the vibrator 100 may vary. Even if made of the same material, the inherent characteristics may differ due to the temperature of the vibrator 100. Here, the inherent characteristics of the vibrator 100 may be, for example, the resonant frequency or impedance.

[0177] In one embodiment, when the temperature of the vibrator 100 reaches the Curie temperature, at least one of the resonant frequency and impedance of the vibrator 100 can be changed.

[0178] The Curie temperature of a material refers to the transition temperature at which a magnetic material changes from a ferromagnetic state to a paramagnetic state, and vice versa. The Curie temperature of the vibrator 100 can be, for example, from about 250°C to about 300°C.

[0179] When electrical energy is continuously applied to the vibrator 100, the oscillating vibrator 100 can generate heat, and therefore the temperature of the vibrator 100 can continue to rise.

[0180] When the temperature of the vibrator 100 reaches the Curie temperature due to continuous heating, the vibrator 100 may malfunction due to sudden changes in impedance or resonant frequency. Therefore, a heat dissipation structure or thermal circulation structure of the vibrator structure 10 may be required to prevent the vibrator 100 from overheating due to the heat generated in the vibrator 100.

[0181] According to one embodiment, the metal body 200 and the support 600 may include a thermally conductive material to receive heat generated from the vibrator 100 to prevent the vibrator 100 from overheating. For example, the metal body 200 and the support 600 may include at least one of stainless steel, silver, copper, and aluminum to receive heat from the vibrator 100.

[0182] The metal body 200 and the support 600 share the heat generated from the vibrator 100 to prevent the temperature from rising to the Curie temperature of the vibrator 100. For example, the heat generated from the vibrator 100 can be transferred along the "A direction" so that the heat of the vibrator 100 can be dissipated. Therefore, heat can be radiated to the outside of the vibrator 100 to prevent the vibrator 100 from overheating, thereby ensuring the stable and continuous operation of the vibrator 100.

[0183] As the mass and / or volume of the metal body 200 and / or support 600, including the thermally conductive material, increases, the metal body 200 and / or support 600 can receive more heat from the vibrator 100, thereby improving the overheat prevention efficiency of the vibrator 100. Furthermore, as the contact area between the vibrator 100 and the metal body 200 and / or between the metal body 200 and the support 600 increases, the heat transfer capacity of the heat generated by the vibrator 100 can be improved, thereby enhancing the heat dissipation efficiency of the vibrator 100.

[0184] In one embodiment, an interface material for improving the heat transfer rate may be applied at the location where the vibrator 100 contacts the metal body 200 or where the metal body 200 contacts the support 600. The interface material may be, for example, thermal grease, but is not limited thereto.

[0185] According to another embodiment, at least one of the metal body 200 and the support 600 may also include at least one heat sink 630. For example, at least one heat sink 630 may be arranged circumferentially along the outer surface of the support 600, or it may be arranged longitudinally (e.g., in the y direction).

[0186] Since the heat sink 630 is also included in the metal body 200 or the support body 600, the heat transfer area with the outside of the vibrator structure 10 is increased, thereby improving the heat dissipation efficiency of the vibrator structure 10.

[0187] Figure 6A This is a perspective view of an aerosol generating apparatus including a cigarette cartridge according to one embodiment. Figure 6B yes Figure 6A A cross-sectional view of a portion of a cigarette cartridge.

[0188] Reference Figure 6A and 6B According to one embodiment, the aerosol generating apparatus 10000 may include a smoke cartridge 2000 having a vibrator structure 10 and a main body 1000.

[0189] The cartridge 2000 may include a liquid storage unit 20, a core 30 for absorbing aerosol-generating material stored in the liquid storage unit 20, and a vibrator structure 10 for atomizing the aerosol-generating material supplied to a vibrator 100 via the core. The vibrator structure 10 may include a vibrator 100 that vibrates due to applied electrical energy. The vibrator 100 may include a first surface and a second surface opposite to the first surface, a first electrode disposed on at least one region of the first surface, a second electrode disposed on at least one region of the second surface, and a metal body 200 that houses the vibrator 100 and contacts at least one region of the first electrode to transfer externally applied electrical energy to the first electrode.

[0190] Applied to Figure 6A and Figure 6B The vibrator structure 10 of the aerosol generating device 10000 can be connected with Figure 4A and Figure 4B The vibrator structure 10 is the same as that in the previous one, and Figure 3A and Figure 3B The vibrator structure described above can also be applied to the aerosol generating device 10000. In the following text, a description of the vibrator structure 10 is omitted, and the description focuses primarily on the smoke cartridge 2000 and the aerosol generating device 10000.

[0191] The main body 1000 may include a battery 1100 for supplying electrical power to the cartridge 2000 and a processor 1200 for controlling the overall operation of the aerosol generating device 10000. Furthermore, the main body 1000 may include other components necessary for the operation of the aerosol generating device 10000. For example, the main body 1000 may include external terminals (not shown) for electrically connecting the vibrator structure 10 in the cartridge 2000 to the main body 1000.

[0192] The aerosol generating device 10000 can be implemented by combining a main body 1000 and a cartridge 2000. For example, when the cartridge 2000 is combined with the main body 1000, external terminals can be electrically connected to the vibrator structure 10. Thus, electrical energy is applied from the battery 1100 to the vibrator structure 10, and the processor 1200 controls the operation of the vibrator structure 10, enabling the aerosol generating device 10000 to operate.

[0193] The mouthpiece 2100 can be located at one end of the cartridge 2000 and can form an exhaust channel 2500 through which aerosol moves along the interior of the cartridge 2000 within the mouthpiece 2100. In addition, the liquid storage unit 20, the core 30, the vibrator structure 10, and the airflow channel (not shown) for introducing external air can be located inside the cartridge 2000.

[0194] The liquid storage unit 20 contains aerosol-generating material and may include a liquid channel 31 for supplying the aerosol-generating material to the vibrator structure 10. For example, the liquid channel 31 may be located between the liquid storage unit 20 and the vibrator structure 10.

[0195] The core 30 may be positioned adjacent to the liquid channel 31 to transfer aerosol-generating material to the vibrator 100. For example, the core 30 may extend from the liquid channel 31 to the first surface 110 of the vibrator 100 to transfer aerosol-generating material present in the liquid storage unit 20 to the vibrator 100. The core 30 may include, but is not limited to, cotton fibers, ceramic fibers, or melamine resin.

[0196] like Figure 6BAs shown, the gap through which the core 30 extends can be located in at least one region of the first elastomer 400. The core 30 is located in this gap and can be connected to the interior of the vibrator structure 10 from the liquid channel 31. That is, aerosol-generating substances can move to the core 30 through the liquid channel 31 and can be transported along the core 30 to the vibrator 100.

[0197] Those skilled in the art will understand that this embodiment can be implemented in modified forms without departing from the scope of the invention. Therefore, the embodiments of the present invention should be considered merely illustrative examples and should not be construed as limiting the scope of the invention. The scope of the invention is described in the claims, not in the foregoing description, and any modifications, substitutions, and improvements to the embodiments of the invention should be interpreted as being included in the invention.
