[0016] In one embodiment, the sub-oscillating member is capable of vibrating the chamber in a direction substantially horizontal and a direction substantially perpendicular to the first direction.

[0017] In one embodiment, the stick may further include a puff sensor that detects airflow inside the stick, and a processor that receives the detection result from the puff sensor and controls the vibration of the vibrating member and the sub-vibrating member based on the detection result.

[0018] In one embodiment, the stick may include a mouthpiece disposed opposite the chamber, an airflow channel configured to provide fluid communication between the chamber and the mouthpiece, and a mash arranged between the airflow channel and the chamber.

[0038] FIG. 1 is a block diagram of an inhaler 100 according to one embodiment.

[0039] Referring to FIG. 1, an inhaler 100 according to one embodiment may include at least some of a control unit 110, a detection unit 120, an output unit 130, a battery 140, a heater 150, a user input unit 160, a memory 170, a communication unit 180, and a driving unit 190.

[0040] However, the internal structure of inhaler 100 is not limited to that shown in Fig. 1. That is, a person skilled in the art will understand that some of the components shown in Fig. 1 may be omitted or new components may be added depending on the design of inhaler 100.

[0041] In one embodiment, the detector 120 can detect the state of the inhaler 100 or the state around the inhaler 100 and transmit the detected information to the controller 110 (or processor). The controller 110 can control the operation of other components of the inhaler 100 based on the detected information.

[0042] For example, the control unit 110 can perform various functions such as controlling the operation of the heater 150 based on the detection result of the detection unit 120, determining whether a stick (e.g., stick 230 in FIG. 2), a capsule (e.g., capsule 232 in FIG. 3a), a cartridge, a cigarette, etc. can be inserted into the insertion groove and controlling the driving unit 190, or displaying a notification on the output unit 130.

[0043] In one embodiment, the detection unit 120 includes at least one of a temperature sensor 122, an insertion detection sensor 124, and a puff sensor 126, but is not limited thereto.

[0044] In one embodiment, the temperature sensor 122 detects the temperature of the heater 150. The inhaler 100 may include a separate temperature sensor that detects the temperature of the heater 150, or the heater 150 itself may function as the temperature sensor. Alternatively, the temperature sensor 122 may be disposed near the battery 140 to monitor the temperature of the battery 140.

[0045] In one embodiment, the insertion detection sensor 124 detects the insertion and / or removal of a stick (e.g., stick 230 in FIG. 2) or a capsule (e.g., capsule 232 in FIGS. 3a and 3b). For example, the insertion detection sensor 124 includes at least one of a film sensor, a pressure sensor, an optical sensor, a resistive sensor, a capacitive sensor, an inductive sensor, and an infrared sensor, and detects a signal change due to the insertion and / or removal of the stick or capsule.

[0046] In one embodiment, the puff sensor 126 detects a user's puff based on various physical changes in the airflow passage or channel. For example, the puff sensor 126 can detect a user's puff based on any one of a temperature change, a flow change, a voltage change, and a pressure change.

[0047] In one embodiment, the detection unit 120 may further include at least one of a temperature / humidity sensor, a barometric pressure sensor, a geomagnetic sensor, an acceleration sensor, a gyroscope sensor, a position sensor (e.g., GPS), a proximity sensor, and an RGB (illuminance) sensor, in addition to the aforementioned sensors.

The display unit 132 may be, for example, a liquid crystal display panel (LCD), an organic light emitting display panel (OLED), or the like. Alternatively, the display unit 132 may display the status of an LED light emitting element.

[0050] In one embodiment, the haptic portion 134 converts electrical signals into mechanical or electrical stimuli to tactilely provide information to the user regarding the inhaler 100. For example, the haptic portion 134 includes a motor, a piezoelectric element, or an electrical stimulator.

[0051] In one embodiment, the acoustic output unit 136 audibly provides the user with information regarding the inhaler 100. For example, the acoustic output unit 136 may convert an electrical signal into an acoustic signal and output it to the outside.

[0052] In one embodiment, battery 140 can provide the power used to operate inhaler 100. Battery 140 provides power to heater 150 to heat.

[0053] In one embodiment, battery 140 provides the power necessary to operate other components included within inhaler 100 (e.g., detection unit 120, output unit 130, user input unit 160, memory 170, and communication unit 180, or drive unit 190). Battery 140 may be a rechargeable battery or a disposable battery. For example, battery 140 may be, but is not limited to, a lithium polymer (LiPoly) battery.

[0054] In one embodiment, heater 150 receives power from battery 140 to heat the aerosol-generating material. Although not shown in FIG. 1 , inhaler 100 may further include a power conversion circuit (e.g., a DC / DC converter) that converts the power of battery 140 and supplies it to heater 150. Furthermore, if inhaler 100 generates aerosol using an induction method, inhaler 100 may further include a DC / AC converter that converts the DC power of battery 140 into AC power.

[0055] In one embodiment, the control unit 110, the detection unit 120, the output unit 130, the user input unit 160, the memory 170, the communication unit 180, and the drive unit 190 may function by receiving power from the battery 140. Although not shown in FIG. 1 , they may further include a power conversion circuit, such as an LDO (low dropout) circuit or a voltage regulator circuit, that converts the power of the battery 140 and supplies it to each component.

[0056] In one embodiment, heater 150 may be formed from any suitable electrically resistive material. For example, suitable electrically resistive materials may 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, nichrome, etc. Additionally, heater 150 may be implemented as, but not limited to, a metal hot wire, a metal hot plate with an electrically conductive track disposed thereon, a ceramic heating element, etc.

[0057] In one embodiment, heater 150 may be an induction heater. For example, heater 150 may include a susceptor that generates heat via a magnetic field applied by a coil to heat the aerosol generating material.

[0058] In one embodiment, heater 150 may include multiple heaters. For example, heater 150 may include a first heater for heating the aerosol-generating article and a second heater for heating the liquid phase.

[0059] In one embodiment, the user input unit 160 may receive information input by a user or output information to a user. For example, the user input unit 160 may be, but is not limited to, a keypad, a dome switch, a touchpad (e.g., a contact-type capacitance type, a pressure-type resistive film type, an infrared detection type, a surface ultrasonic conduction type, an integral tension measurement type, a piezoelectric effect type, etc.), a jog wheel, a jog switch, etc. Although not shown in FIG. 1 , the inhaler 100 may further include a connection interface such as a universal serial bus (USB) interface, through which the inhaler 100 may be connected to another external device to transmit and receive information or charge the battery 140.

[0060] In one embodiment, memory 170 is hardware that stores various data processed within inhaler 100, and stores data that has been processed by control unit 110 and data to be processed by control unit 110. Memory 170 includes at least one type of storage medium from the following: a flash memory type, a hard disk type, a multimedia card micro type, a card-type memory (e.g., SD or xD memory), a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, and an optical disk.

[0061] In one embodiment, memory 170 stores data such as the operating time of inhaler 100, the maximum number of puffs, the current number of puffs, at least one temperature profile, and data relating to the user's smoking patterns.

[0062] In one embodiment, the communication unit 180 includes at least one component for communication with other electronic devices. For example, the communication unit 180 includes a short-range communication unit 182 and a wireless communication unit 184.

[0063] In one embodiment, the short-range wireless communication unit 182 includes, but is not limited to, a Bluetooth communication unit, a BLE (Bluetooth Low Energy) communication unit, a Near Field Communication unit, a WLAN (Wi-Fi) communication unit, a Zigbee communication unit, an IrDA (Infrared Data Association) communication unit, a WFD (Wi-Fi Direct) communication unit, a UWB (Ultra Wideband) communication unit, an Ant+ communication unit, etc.

[0064] In one embodiment, the wireless communication unit 184 includes, but is not limited to, a cellular network communication unit, an Internet communication unit, a computer network (e.g., a LAN or WAN) communication unit, etc. The wireless communication unit 184 may also use subscriber information (e.g., an International Mobile Subscriber Identity (IMSI)) to identify and authenticate the inhaler 100 within the communication network.

[0065] In one embodiment, the driver 190 may include various drivers to assist the user in inhaling the inhaler 100. For example, the driver 190 may include a vibrating member 191 to assist in the delivery of powder from the inhaler 100.

[0066] In one embodiment, the vibrating member 191 may be implemented as an electronic vibrator, and may generate vibrations in response to application of a voltage (e.g., an AC voltage). Without being limited thereto, the driving unit 190 may further include elements such as a motor, a shaft, multiple pinions, or a hydraulic device.

[0067] In one embodiment, the controller 110 controls the overall operation of the inhaler 100. In one embodiment, the controller 110 may include at least one processor. The processor may be implemented as an array of multiple logic gates, or may be implemented as a combination of a general-purpose microprocessor and memory storing a program executable by the microprocessor. The controller 110 may also be implemented as other types of hardware, as would be understood by a person of ordinary skill in the art to which the present invention pertains.

[0068] In one embodiment, the control unit 110 can control the temperature of the heater 150 by controlling the supply of power from the battery 140 to the heater 150. For example, the control unit 110 may control the power supply by controlling the switching of a switching element between the battery 140 and the heater 150. As another example, a heating direct circuit may control the power supply to the heater 150 in response to a control command from the control unit 110.

[0069] In one embodiment, the control unit 110 may analyze the result detected by the detection unit 120 and control the processing to be performed thereafter. For example, the control unit 110 may control the power supplied to the heater 150 so as to start or stop the operation of the heater 150 or the driving unit 190 based on the result detected by the detection unit 120.

[0070] For example, based on the results detected by the detection unit 120, the control unit 110 can control the amount of power supplied to the heater 150 and the time for which power is supplied so that the heater 150 can heat up to a predetermined temperature or maintain an appropriate temperature.

[0071] In one embodiment, the control unit 110 controls the output unit 130 based on the result detected by the detection unit 120. For example, when the number of puffs counted via the puff sensor 126 reaches a preset number, the control unit 110 may notify the user that the inhaler 100 will soon be terminated via at least one of the display unit 132, the haptic unit 134, and the audio output unit 136. Alternatively, for example, the puff sensor 126 may detect the user's inhalation state, and the control unit 110 may control the driving of the vibration member 191 of the driving unit 190 based on the detected state.

[0072] In one embodiment, the control unit 110 may control the time and / or amount of power supply to the heater 150 depending on the state of the stick or capsule detected by the detection unit 120 .

[0073] An embodiment may also be embodied in the form of a recording medium containing computer-executable instructions, such as program modules, executed by a computer. Computer-readable media may be any available medium that can be accessed by a computer, including both volatile and nonvolatile media, and both detachable and non-detachable media. Computer-readable media may also include both computer storage media and communication media. Computer storage media includes both volatile and non-volatile, detachable and non-detachable media embodied in any method or technology for storage of information, such as computer-readable instructions, data structures, program modules, or other data. Communication media typically include computer-readable instructions, data structures, other data in a modulated data signal, such as a program module, or other transmission mechanism, and includes any information delivery media.

[0074] FIG. 2 is a schematic diagram of an inhaler 200 according to one embodiment.

[0075] Referring to FIG. 2, an inhaler 200 according to one embodiment includes at least one of a holder 210 and a stick 230.

[0076] In one embodiment, the holder 210 may be configured in a cylindrical or polygonal column shape. An insertion groove 215 for inserting the stick 230 is formed in the holder 210, and the stick 230 may be inserted into the insertion groove 215 in a first direction (e.g., the -Y direction).

[0077] In one embodiment, the holder 210 includes a first surface 211, a second surface 212, and a side surface 213. An insertion groove 215 may be formed in the first surface 211, and the second surface 212 may be the surface opposite to the first surface 211. A side surface 213 may be formed between the first surface 211 and the second surface 212.

[0078] In one embodiment, the insertion groove 215 may be a recess formed in the first surface 211 .

[0079] For example, the insertion groove 215 may have a shape that extends along the longitudinal axis (e.g., ±Y direction) of the holder 210. The stick 230 is inserted into the holder 210 in a direction that passes through the insertion groove 215 (e.g., −Y direction, or “first direction”).

[0080] In one embodiment, an inlet (not shown) may be formed between the outside of the holder 210 and the insertion groove 215 to allow air outside the holder 210 to flow into the insertion groove 215 .

[0081] Although not shown in the drawings, holder 210 houses various components of inhaler 200 therein, for example, holder 210 may house at least a portion of a control unit (e.g., control unit 110 in FIG. 1), at least one sensor (e.g., detection unit 120 in FIG. 1), and a battery (e.g., battery 140 in FIG. 1).

[0082] In one embodiment, the stick 230 is configured in the shape of a cylinder or a polygonal pillar, and has a size and shape that allows it to be inserted into the insertion groove 215 of the holder 210. The stick 230 contains the powder P inside.

[0083] In one embodiment, the mouthpiece 231 may be provided at one end of the stick 230. For example, the mouthpiece 231 may be provided in a direction opposite to the region where the stick 230 is inserted into the insertion groove 215 (e.g., the chamber 233 in FIG. 3a). A user can inhale air by applying negative pressure to the stick 230. For example, the user may inhale the powder P or air or aerosol containing the powder P while biting the mouthpiece 231.

[0084] FIG. 3a is a schematic view of the interior of an inhaler 200 according to one embodiment, and FIG. 3b is a schematic view of the interior of an inhaler 200 according to one embodiment.

[0085] Specifically, Figures 3a and 3b are views of the interior of area A shown in Figure 2, with Figure 3a showing the state in which stick 230 is partially inserted or in the process of being inserted into insertion groove 215 of holder 210, and Figure 3b showing the state in which stick 230 is substantially fully inserted into insertion groove 215 of holder 210.

[0086] 3a and 3b, an inhaler 200 according to one embodiment may include at least a portion of a piercing member 220, a resilient member 225, a chamber 233, and a piercing hole 234.

[0087] In one embodiment, the stick 230 includes a chamber 233 for accommodating the capsule 232. The chamber 233 may be a portion of the stick 230 that is inserted into the insertion groove 215. The chamber 233 may be a space for accommodating or storing the capsule 232, or may be a space for restricting the movement of the capsule 232.

[0088] In one embodiment, capsule 232 contains powder P therein. Powder P may be tobacco extract in small particle form, or powder P may be a composition or functional substance including a pharmacological substance such as caffeine, taurine, aspirin, a sedative, a hypnotic, a bronchodilator, a vaccine, or a substance such as free nicotine or nicotine salt. However, this is merely an example, and powder P inside capsule 232 may be replaced with a liquid, a gas, or some combination thereof.

[0089] In one embodiment, the pierce hole 234 is an opening that opens toward the chamber 233 so that the chamber 233 is exposed to the outside of the stick 30. The pierce hole 234 may be formed on the surface of the stick 230 facing the insertion groove 215, preferably in the area facing the piercing member 220. The pierce hole 234 may be larger than or the same size as the circumference of the piercing member 220.

[0090] In one embodiment, the stick 230 includes an airflow channel 235 that provides fluid communication between the chamber 233 and a mouthpiece (e.g., mouthpiece 231 in FIG. 2). The airflow channel 235 is a passage through which air containing the powder P flows, and the airflow channel 235 and the chamber 233 can be separated by a mesh 236.

[0091] In one embodiment, mesh 236 allows powder P and air to pass through while restricting the passage of capsules 232 or other foreign objects. Mesh 236 also filters out some of powder P and prevents powder P from clumping. For example, the diameter of a single hole in mesh 236 may be 5 micrometers.

[0092] In one embodiment, when capsule 232 is crushed, at least a portion of the powder P inside capsule 232 is released into chamber 233. When the user inhales air from stick 230 through mouthpiece 231, powder P passes through mesh 236 and travels through airflow channel 235 to mouthpiece 231, where it is inhaled by the user.

[0093] In one embodiment, the stick 230 may be disposable, and once the powder P is depleted, it may be replaced with another stick 230. Alternatively, the stick 230 may be reusable, and once the powder P is depleted, the stick 230 may be refilled with the capsule 232 or powder P and used again.

[0094] In one embodiment, the piercing member 220 is disposed in the insertion groove 215 and may protrude from the insertion groove 215 in a direction (e.g., the +Y direction) toward the stick 230. The piercing member 220 may crush the capsule 232. For example, when the stick 230 is inserted into the insertion groove 215 in a first direction (e.g., the -Y direction), at least a portion of the piercing member 220 penetrates the piercing hole 234 and is inserted into the chamber 233 of the stick 230, causing the piercing member 220 to partially crush the capsule 232.

[0095] In one embodiment, the distal end of the piercing member 220 may have a sharp or pointed shape. For example, the piercing member 220 may be a needle or a sting. The distal end of the piercing member 220 fractures a portion of the capsule 232, forming a perforation in the capsule 232. The capsule 232 may release the powder P into the chamber 233 through the perforation fractured by the piercing member 220.

[0096] According to an embodiment, the elastic member 225 may be provided in the insertion groove 215. When the stick 230 is inserted into the insertion groove 215, the elastic member 225 is deformed (e.g., compressed) by the stick 230. When the elastic member 225 is deformed, the elastic member 225 presses the stick 230 in a direction opposite to the first direction (e.g., the +Y direction) due to its elastic force. The elastic member 225 may be formed of a coil spring that applies the elastic force.

[0097] FIG. 4a is a schematic diagram illustrating the interior of an inhaler 200 according to one embodiment.

[0098] Referring to FIG. 4a, an inhaler 200 according to one embodiment includes a vibration member 250 (eg, vibration member 191 of FIG. 1).

[0099] In one embodiment, when capsule 232 is crushed by piercing member 220, a perforation communicating with chamber 233 is formed in capsule 232, and at least a portion of powder P inside capsule 232 is released into chamber 233 through the perforation. Powder P released into chamber 233 passes through mesh 236 and is conveyed to airflow channel 235, passes through airflow channel 235 and a mouthpiece (e.g., mouthpiece 231 in FIG. 2) and is inhaled by the user.

[0100] In one embodiment, the amount of powder P that a user can inhale may also vary based on various parameters related to the powder P released from the capsule 232 (e.g., the amount of powder P released per unit time, the density of the powder P in the air passing through the airflow channel 235, or the degree of diffusion of the released powder P).

[0101] In one embodiment, by controlling the amount of powder P released from capsule 232 per unit time (hereinafter referred to as the "amount of powder P released") via vibration member 250, inhaler 200 can provide powder P to the user in a manner suitable for the user's conditions, usage environment, or user preferences.

[0102] In one embodiment, the vibration member 250 may provide vibration to the piercing member 220. Alternatively, the vibration member 250 may directly or indirectly vibrate at least one of the capsule 232, the powder P, or the chamber 233. For ease of explanation, one embodiment of the inhaler 200 will be described below with reference to the drawings, focusing on the vibration member 250 that vibrates the piercing member 220.

[0103] In one embodiment, the vibration member 250 may be implemented as an electronic vibrator that generates vibrations when a voltage (e.g., an AC voltage) is applied, but is not limited thereto and may be implemented with various structures and configurations that can provide vibrations to the piercing member 220.

[0104] In one embodiment, the vibration member 250 applies vibrations to the piercing member 220 to assist in the ejection of the powder P from the capsule 232. When the vibration member 250 vibrates the piercing member 220, the perforation formed in the capsule 232 becomes larger, or the vibrations are transmitted to the capsule 232 or the powder P, increasing the amount of powder P ejected.

[0105] In one embodiment, the vibration member 250 can vibrate the piercing member 220 in a direction (e.g., + / -Y direction) substantially parallel to the direction in which the stick 230 is inserted into the holder 210, i.e., the first direction (e.g., the -Y direction).

[0106] In one embodiment, when the vibrating member 250 vibrates in a direction substantially horizontal to the first direction, it is effective in expelling powder P stagnating between the capsule 232 and the piercing member 220. Alternatively, there is an advantage in that the diameter of the piercing hole 234 does not need to be increased to ensure the vibration radius of the piercing member 220, thereby preventing the powder P from being expelled to the outside of the stick 230 through the piercing hole 234. Alternatively, the vibration of the vibrating member 250 is mainly transmitted to the piercing member 220 and the capsule 232, reducing or preventing the stick 230 or the holder 210 from vibrating.

[0107] In one embodiment, the vibration member 250 can vibrate the piercing member 220 in a direction (e.g., an XZ plane direction) substantially perpendicular to the direction in which the stick 230 is inserted into the holder 210, i.e., a first direction (e.g., a -Y direction). The vibration of the piercing member 220 is transmitted to the capsule 232, and the vibration of the capsule 232 can promote the release of the powder P.

[0108] In one embodiment, when the vibration member 250 vibrates in a direction substantially perpendicular to the first direction, the piercing member 220 can increase the size of the perforation, or the piercing member 220 can effectively release the powder P by securing a space between the capsule 232 and the piercing member 220. Alternatively, the capsule 232 repeatedly collides with the chamber 233 due to the vibration, thereby increasing the amount of the powder P released.

[0109] In one embodiment, the vibration member 250 can vibrate the piercing member 220 in a direction substantially horizontal and a direction substantially vertical to the first direction. The vibration member 250 vibrates the capsule 232 three-dimensionally via the piercing member 220, thereby further increasing the amount of powder P released compared to simple unidirectional reciprocating motion.

[0110] In various embodiments, the inhaler 200 may need to decrease or increase the amount or rate of release of powder P released from the capsule 232 depending on various factors, such as the user's breathing rate, or user preference. A single size perforation makes it difficult to accommodate different environments and different user needs.

[0111] For example, if the perforations are large, a large amount of powder P is released in a short period of time, causing the density of the powder P inhaled by the user to be irregular or significantly increased. Alternatively, if the perforations are small, it becomes difficult to release the powder P, and a user with limited lung capacity may have difficulty inhaling the powder P. In one embodiment, the vibration member 250 can be controlled to provide vibration to the capsule 232 so that the powder P is efficiently released from the capsule 232.

[0112] By forming relatively small perforations in the capsule 232 and controlling the amount of powder P released from the capsule 232 per unit time via the vibration member 250, the inhalation density of the powder P by the user can be controlled.

[0113] FIG. 4b is a schematic diagram illustrating the interior of an inhaler 200 according to one embodiment.

[0114] Referring to FIG. 4b, an inhaler 200 according to one embodiment includes a sub-vibration member 255 (eg, vibration member 191 of FIG. 1).

[0115] In describing FIG. 4b, the overlapping details with those described above regarding the inhaler 200 will be omitted.

[0116] In one embodiment, the sub-vibration member 255 can provide vibration to the chamber 233. The sub-vibration member 255 can directly or indirectly vibrate the chamber 233 to assist the powder P released into the chamber 233 to move into the airflow channel 235. Alternatively, the sub-vibration member 255 can assist the vibration member 250 to promote the release of the powder P from the capsule 232.

[0117] 4b, the sub-vibration member 255 may be coupled to the elastic member 225 and provide vibration to the chamber 233 via the elastic member 225. Alternatively, and without being limited thereto, the sub-vibration member 255 may be realized in various structures for transmitting vibration to the chamber 233. For example, the sub-vibration member 255 may be directly coupled to the stick 230, or the sub-vibration member 255 may be disposed in the holder 210 and have a structure for applying an impact to the stick 230.

[0118] In one embodiment, the chamber 233 can provide kinetic energy to the powder P in the chamber 233 by vibrating. Furthermore, the vibration of the chamber 233 causes the powder P to be evenly dispersed and move along the airflow. Furthermore, the vibration of the chamber 233 can be transmitted to the capsule 232, and the sub-vibration member 255 can vibrate the capsule 232 to promote the release of the powder P.

[0119] In one embodiment, the sub-vibration member 255 can vibrate the chamber 233 in a direction (e.g., + / -Y direction) substantially horizontal to the direction in which the stick 230 is inserted into the holder 210, i.e., the first direction (e.g., the -Y direction). In this case, the elastic member 255 can assist and strengthen the vibration of the sub-vibration member 255. Vibrating the chamber 233 in a direction substantially horizontal to the first direction is advantageous in moving the powder P remaining on the bottom surface of the chamber 233. In this case, there is no need to increase the opening of the insertion groove 215 separately for vibrating the chamber 233.

[0120] In one embodiment, the sub-vibration member 255 can vibrate the chamber 233 in a direction in which the stick 230 is inserted into the holder 210, i.e., in a direction substantially perpendicular to the first direction (e.g., in the XZ plane direction). In this case, the chamber 233 can repeatedly strike the capsule 232, effectively inducing the release of the powder P. Furthermore, by vibrating the chamber 233 in a direction substantially perpendicular to the first direction, the powder P can be evenly dispersed in a substantially horizontal direction in the chamber 233.

[0121] In one embodiment, the sub-vibration member 255 can vibrate the chamber 233 in a direction substantially horizontal and a direction substantially vertical to the first direction. The sub-vibration member 255 can further increase the amount of powder P released by vibrating the chamber 233 three-dimensionally compared to a simple reciprocating motion in one direction.

[0122] In one embodiment, a processor (e.g., processor 110 in FIG. 1) acquires information regarding the operation of inhaler 200 from various types of sensors (e.g., detection unit 120 in FIG. 1), and based on that information, can change various factors such as the vibration frequency, vibration intensity, and vibration time of vibration member 250 and / or sub-vibration member 255 to control their respective vibrations.

[0123] For example, if the processor 110 receives information about the airflow inside the stick 230 via a puff sensor (e.g., the puff sensor 126 in Figure 1) and determines that the airflow is insufficient, the processor 110 can increase the vibration intensity or frequency of the vibration member 250 and / or the sub-vibration member 255 to increase the amount of powder P emitted.

[0124] Alternatively, the processor 110 can receive a separate input signal from a user input unit (e.g., the user input unit 160 in FIG. 1) or a communication unit (e.g., the communication unit 180 in FIG. 1) and control the vibration of the vibration member 250 and / or the sub-vibration member 255 based on the input signal.

[0125] For example, the processor 110 can control the vibration of the vibrating member 250 and / or the sub-vibrating member 255 depending on various factors such as the user's lung capacity, the user's preferences, the usage environment, etc. The inhaler 200 of various embodiments herein can assist the user in inhaling powder P smoothly and can provide a user-customized inhaler 200.

[0126] Figure 5a is a cross-sectional view of a stick 230 according to one embodiment, and Figure 5b is a cross-sectional view of a stick 230 according to one embodiment. Specifically, Figures 5a and 5b are cross-sectional views of a partial area of ​​stick 230 in a state separated from holder 210.

[0127] 5a and 5b, the stick 230 includes at least one of a sealing member 237 or a door 238.

[0128] 5a, the sealing member 237 can seal the piercing hole 234. The sealing member 237 can be broken by the piercing member 220 when the stick 230 is inserted into the insertion groove 215. For example, the stick 230 can be disposable. Alternatively, the stick 230 can be reused by replacing the sealing member 237 and capsule 232 after they are broken.

[0129] In one embodiment, the sealing member 237 can protect the chamber 233 from water or foreign matter entering the chamber 233 during manufacturing and transportation of the stick 230. In addition, the sealing member 237 can limit the area of ​​the pierced hole 234 that is broken by the piercing member 220, and prevent the powder P from being released to the outside of the stick 230 through the pierced hole 234.

[0130] 5b, a door 238 may selectively open and close the piercing hole 234. The door 238 may be opened before or while the stick 230 is inserted into the insertion groove 215. The door 238 moves by a door hinge 239.

[0131] For example, the door hinge 239 may allow the door 238 to move in a substantially horizontal direction (eg, in the XZ plane) or tilt in a substantially vertical direction (eg, in the + / -Y direction).

[0132] In one embodiment, the door 238 may be open when the inhaler 200 is in use or ready to be used, and may be closed when the inhaler 200 is not in use. The door 238 may protect the chamber 233 from water or foreign matter entering the chamber 233 during the manufacturing and transportation of the stick 230. Alternatively, the used or crushed capsule 232 in the chamber 233 may be replaced through the door 238.

[0133] In one embodiment, a processor (e.g., processor 110 in FIG. 1) can acquire information about the coupling of stick 230 from various types of sensors (e.g., detectors in FIG. 1) and control the actuation of door hinge 239 based on the information.

[0134] For example, the processor 110 may detect whether the stick 230 has been inserted into the insertion groove 215 via an insertion detection sensor (e.g., the insertion detection sensor 124 in FIG. 1 ), and based on that, may control the door hinge 239 to open the door 238 so that the piercing member 220 can pass through the piercing hole 234. Alternatively, and without being limited thereto, the door 238 may be opened and closed manually by the user. For example, the user may directly open and close the door 238, or the inhaler 200 may be provided with a separate switch (not shown) connected to the door 238, and the user may open and close the door 238 by operating the switch (not shown).

For example, the described techniques may be performed in an order different from that described, and / or the components of the described systems, structures, devices, circuits, etc. may be combined or combined in a form different from that described, or may be replaced or substituted with other components or equivalents, and still achieve appropriate results.
