Summary of the Invention

Problems to be Solved by the Invention

[0004] [[ID=二十六]]An aerosol generating device that generates aerosol from a liquid-phase aerosol generating substance includes a storage tank that stores the liquid-phase aerosol generating substance. When the aerosol generating device is used, the pressure in the storage tank becomes relatively low, and as a result, air may flow backward through the wick. When air backflow occurs, the movement of the aerosol generating substance in the storage tank is obstructed, and the efficiency of liquid-phase transfer in the storage tank decreases.

[0005] To solve this, there is a technical requirement to prevent a drop in air pressure in the storage tank that stores the aerosol generating substance and to keep the inside of the storage tank at atmospheric pressure.

Means for Solving the Problems

[0006] An aerosol generator according to one embodiment includes a storage tank for storing a liquid-phase aerosol-generating substance, a core through which the aerosol-generating substance from the storage tank is transmitted, a vibrator that generates vibrations in the core to atomize the aerosol-generating substance, an aerosol channel through which the aerosol generated by the vibrator flows, a mouthpiece including an intake port that selectively interlocks with the aerosol channel and is hinge-driven with respect to a hinge axis, and an air channel that opens in the direction toward the mouthpiece from the inside of the storage tank and is opened or closed by the hinge-driven mouthpiece.

[0007] In one embodiment, the mouthpiece can be hinged between a first position in which the aerosol channel and the suction port are not in communication and a second position in which the aerosol channel and the suction port are in communication.

[0008] In one embodiment, the mouthpiece can close the air passage in the first position and open the air passage in the second position.

[0009] In one embodiment, the aerosol generator may further include a sealing member that seals the air passage when the mouthpiece is in the first position.

[0010] In one embodiment, the sealing member can be inserted into the air passage while the mouthpiece is in the first position.

[0011] In one embodiment, the sealing member is made of an elastic material such as rubber, silicone, or TPU (thermoplastic polyurethane).

[0012] In one embodiment, the aerosol generator may further include an auxiliary channel that is open to the air channel on one side and communicates with the aerosol channel on the other side opposite to the one side.

[0013] In one embodiment, the aerosol generator may further include an elastic member that is arranged inside the air passage to surround one side of the auxiliary passage and is deformed based on changes in air pressure in the auxiliary passage.

[0014] In one embodiment, the elastic member deforms when the air pressure in the auxiliary channel decreases, thereby opening the air channel.

[0015] In one embodiment, the elastic member is made of an elastic material such as rubber, silicone, or TPU (thermoplastic polyurethane).

[0016] In one embodiment, the aerosol generator may further include the leak prevention member according to claim 8, which is provided inside the air passage and is separated from the elastic member by at least a portion of its area when the air pressure in the auxiliary passage decreases and the elastic member is deformed.

[0017] In one embodiment, the storage tank may further include a valve for opening and closing the air passage.

[0018] In one embodiment, the aerosol generator may further include a processor that controls the driving of the vibrator and the valve.

[0019] In one embodiment, the processor can open the valve when the vibration is started to be driven.

[0020] In one embodiment, the processor can open the valve when it detects that the hinge of the mouthpiece has been driven. [Effects of the Invention]

[0021] An aerosol generator including an air passage according to one embodiment can maintain smooth movement of liquid-phase aerosol-generating material by preventing a pressure drop in the storage tank and maintaining it at atmospheric pressure.

[0022] Alternatively, an aerosol generating apparatus including an air flow path according to one embodiment can open and close the air flow path based on a user's usage operation (e.g., mouthpiece opening and / or mouthpiece suction), and can prevent backflow or leakage of the liquid-phase aerosol product substance.

[0023] The effects of an aerosol generating apparatus including an air flow path according to one embodiment are not limited to those mentioned above, and different effects not mentioned can be clearly understood by those skilled in the art from the following description.

[0039] The terminology used in the embodiments has been selected as widely used and general terms as possible, taking into account the functions of the present invention; however, this may change depending on the intentions of the articulators, precedents, the emergence of new technologies, etc. In certain cases, the applicant has selectively selected some terms, in which case their meaning will be described in detail in the description of the invention. Therefore, the terms used in the present invention should not be merely names of terms, but should be defined based on the meaning of the terms and the overall content of the present invention.

[0040] Throughout the specification, when a part "includes" a component, this means, unless otherwise specified, that it may include other components rather than excluding them. Furthermore, terms such as "~part" and "~module" used in the specification refer to a unit that processes at least one function or operation, which may be embodied in hardware or software, or in a combination of hardware and software.

[0041] As used herein, when an expression such as “at least one of the following” precedes an array of components, it modifies the entire array of components, not each of the individual components. For example, the expression “at least one of a, b, and c” should be interpreted as including a, b, c, or a and b, a and c, b and c, or a, b, and c.

[0042] In various embodiments, the “aerosol-generating article” refers to an article that contains a medium, through which an aerosol passes and the medium is transferred. A typical example of an aerosol-generating article is a cigarette, but the scope of this disclosure is not limited to this.

[0043] In various embodiments, "upstream" or "upstream direction" means the direction away from the user's (smoker's) mouth, and "downstream" or "downstream direction" means the direction closer to the user's mouth. The terms upstream and downstream are used to describe the relative positions of the elements constituting the aerosol generating article.

[0044] In various embodiments, "puff" refers to the user's inhalation, which means the substance being drawn into the user's mouth, nose, or lungs.

[0045] In one embodiment, the aerosol generator is a device that generates an aerosol by electrically heating a cigarette contained in an internal space.

[0046] In one embodiment, the aerosol generator includes a heater. In one embodiment, the heater is an electrical resistance heater. For example, the heater includes an electrical conductive track, and when an electric current flows through the electrical conductive track, the heater is heated.

[0047] In one embodiment, the heater includes a tubular heating element, a plate-shaped heating element, a needle-shaped heating element, or a rod-shaped heating element, and may heat the inside or outside of the rolled tobacco depending on the shape of the heating element.

[0048] In one embodiment, the cigarette includes a tobacco rod and a filter rod. The tobacco rod may be made of a sheet or a strand, and the tobacco sheet may be made of finely shredded tobacco. The tobacco rod may also be surrounded by a heat-conducting material. For example, the heat-conducting material may be, but is not limited to, a metal foil such as aluminum foil.

[0049] In one embodiment, the filter rod is a cellulose acetate filter. The filter rod is composed of at least one segment. For example, the filter rod includes a first segment for cooling the aerosol and a second segment for filtering out predetermined components contained in the aerosol.

[0050] In one embodiment, the aerosol generator is a device that generates aerosols using a cartridge containing an aerosol-generating substance.

[0051] In one embodiment, the aerosol generator includes a cartridge containing an aerosol-generating substance and a body supporting the cartridge. The cartridge may, but is not limited to, be detachably coupled to the body. The cartridge may be formed or assembled integrally with the body and fixed so as not to be detached by the user. The cartridge may be attached to the body with the aerosol-generating substance contained inside. However, it is not limited to this, and the aerosol-generating substance may be injected into the cartridge while the cartridge is coupled to the body.

[0052] In one embodiment, the cartridge may contain an aerosol-generating substance in any one of several states, such as liquid, solid, gaseous, or gel. The aerosol-generating substance may include a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing substance that includes components of volatile tobacco flavor, or a liquid containing a non-tobacco substance.

[0053] In one embodiment, the cartridge can function to generate an aerosol by converting the phase of the aerosol-generating substance inside the cartridge to a gaseous phase, through operation by an electrical signal or wireless signal transmitted from the main unit. An aerosol refers to a gaseous state in which vaporized particles generated from the aerosol-generating substance and air are mixed.

[0054] In various embodiments, an aerosol generator can generate an aerosol by heating a liquid composition, and the generated aerosol is transmitted to the user through a cigarette. That is, the aerosol generated from the liquid composition moves along an airflow passage of the aerosol generator, and the airflow passage is configured so that the aerosol is transmitted to the user through a cigarette.

[0055] In various embodiments, the aerosol generator may be a device that generates aerosols from aerosol-generating material using an ultrasonic vibration method. In this case, the ultrasonic vibration method means a method of generating aerosols by atomizing the aerosol-generating material with ultrasonic vibrations generated by a transducer.

[0056] In one embodiment, the aerosol generator may include a transducer that generates short-period vibrations to atomize the aerosol-generating substance. The vibrations generated by the transducer may be ultrasonic vibrations, and the frequency band of the ultrasonic vibrations may be, but is not limited to, a frequency band of approximately 100 kHz to approximately 3.5 MHz.

[0057] In one embodiment, the aerosol generator may further include a core that absorbs the aerosol-generating substance. For example, the core may be positioned to surround at least one region of the oscillator, or to be in contact with at least one region of the oscillator.

[0058] In one embodiment, when a voltage (e.g., an AC voltage) is applied to the transducer, heat and / or ultrasonic vibrations may be generated from the transducer, and the heat and / or ultrasonic vibrations generated from the transducer are transmitted to the aerosol-generating material absorbed in the core. The aerosol-generating material absorbed in the core is converted into a gaseous phase by the heat and / or ultrasonic vibrations transmitted from the transducer, and as a result, an aerosol can be generated.

[0059] For example, the viscosity of the aerosol-generating material absorbed into the core decreases due to the heat generated from the transducer, and the aerosol is generated when the aerosol-generating material with reduced viscosity is broken down into fine particles by the ultrasonic vibrations generated from the transducer, but this is not limited to this.

[0060] In various embodiments, the aerosol generator may be a device that generates aerosols by heating the aerosol product contained within the aerosol generator using induction heating.

[0061] In one embodiment, the aerosol generator may include a susceptor and a coil. In one embodiment, the coil applies a magnetic field to the susceptor. Power is supplied to the coil from the aerosol generator, forming a magnetic field inside the coil. In one embodiment, the susceptor may be a magnetic material that generates heat in response to an external magnetic field. The aerosol product is heated as the susceptor generates heat when a magnetic field is applied to it while it is located inside the coil. Alternatively, the susceptor may be selectively located within the aerosol product.

[0062] In various embodiments, the aerosol generator may further include a cradle.

[0063] In one embodiment, the aerosol generator may be configured with a separate cradle. For example, the cradle charges the battery of the aerosol generator. Alternatively, the heater is heated while the cradle and the aerosol generator are coupled together.

[0064] The following describes embodiments of the present disclosure in detail, with reference to the attached drawings, so that they can be easily implemented by a person skilled in the art. The present disclosure can be implemented in a manner that can be embodied in the various embodiments of aerosol generators described above, or in a variety of different manners, and is not limited to the embodiments described herein.

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

[0082] In one embodiment, the heater 150 may be an induction heating type heater. For example, the heater 150 may include a susceptor that generates heat through a magnetic field applied by a coil to heat the aerosol-generating substance.

[0083] In one embodiment, the heater 150 may include a plurality of heaters. For example, the heater 150 may include a first heater for heating the aerosol generating article and a second heater for heating the liquid.

[0084] In one embodiment, the user input unit 160 can receive information input from the user or output information to the user. For example, the user input unit 160 may be a key pad, a dome switch, a touch pad (contact-type capacitive type, pressure-type resistive type, infrared detection type, surface ultrasonic conduction type, integral tension measurement type, piezoelectric effect type, etc.), a jog wheel, a jog switch, etc., but is not limited thereto. Although not shown in Figure 1, the aerosol generator 100 may also include a connection interface such as a USB (universal serial bus) interface, and can connect to other external devices via the connection interface to send and receive information or charge the battery 140.

[0085] In one embodiment, the memory 170 is hardware that stores various data processed within the aerosol generator 100, and stores data processed by the control unit 110 and data to be processed. The memory 170 may include at least one type of storage medium, such as flash memory type, hard disk type, multimedia card micro type, card type memory (e.g., SD or XD memory), RAM (random access memory), SRAM (static random access memory), ROM (read-only memory), EEPROM (electrically erasable programmable read-only memory), PROM (programmable read-only memory), magnetic memory, magnetic disk, or optical disk. The memory 170 stores data such as the operating time of the aerosol generator 100, the maximum number of puffs, the current number of puffs, at least one temperature profile, and the user's smoking pattern.

[0089] In one embodiment, the control unit 110 may control the overall operation of the aerosol generator 100. In one embodiment, the control unit 110 may include at least one processor. The processor may be embodied as an array of logic gates, or as a combination of a general-purpose microprocessor and memory containing a program that can be executed by this microprocessor. It will be understood by those ordinary skill in the art to which this embodiment belongs that it may also be embodied as other forms of hardware.

[0090] In one embodiment, the control unit 110 may 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 controls the power supply by controlling the switching of a switching element between the battery 140 and the heater 150. In another example, a direct heating circuit may control the power supply to the heater 150 according to a control command from the control unit 110.

[0091] In one embodiment, the control unit 110 may analyze the results detected by the detection unit 120 and control subsequent processing. For example, the control unit 110 controls the power supplied to the heater 150 so that the heater 150 starts or stops operating, based on the results detected by the detection unit 120. In another example, the control unit 110 can control the amount of power supplied to the heater 150 and the duration of power supply so that the heater 150 is heated to a predetermined temperature or maintained at an appropriate temperature, based on the results detected by the detection unit 120.

[0092] In one embodiment, the control unit 110 may control the output unit 130 based on the results detected by the detection unit 120. For example, when the number of puffs counted through the puff sensor 126 reaches a pre-set number, the control unit 110 can notify the user that the aerosol generator 100 will immediately shut off through at least one of the display unit 132, the haptic unit 134, and the acoustic output unit 136.

[0093] In one embodiment, the control unit 110 may control the power supply time and / or power supply amount to the heater 150 based on the state of the aerosol-generating article detected by the detection unit 120. For example, if the aerosol-generating article is in an over-humid state, the control unit 110 can control the power supply time to the induction coil to increase the preheating time compared to when the aerosol-generating article is in a normal state.

[0094] One embodiment may also be embodied in the form of a recording medium containing computer-executable instruction words, such as a program module executed by a computer. Computer-readable media may be any available medium accessible by a computer, and include all volatile and non-volatile media, separable and non-separable media. Computer-readable media may also include all computer storage media and communication media. Computer storage media include all volatile and non-volatile, separable and non-separable media embodied in any method or technique for storing information such as computer-readable instruction words, data structures, program modules, or other data. Communication media typically include computer-readable instruction words, data structures, program modules, or other data such as modulated data signals, or other transmission mechanisms, and include any information transmission medium.

[0095] Figure 2 is a schematic diagram showing an aerosol generator 100 according to one embodiment.

[0096] Referring to Figure 2, the aerosol generator 100 according to one embodiment includes a cartridge 10 and a main body 50. Some components of the aerosol generator 100 described in Figure 2 and subsequent figures are substantially the same as or similar to some components of the aerosol generator 100 described in detail with reference to Figure 1, and redundant content will be omitted below.

[0097] In one embodiment, the cartridge 10 contains an aerosol-generating substance and is detachably fastened to the main body 50. For example, at least a portion of the cartridge 10 is inserted into the interior of the main body 50 (for example, the fastening area of ​​the cartridge 10 in Figure 3a) to connect the cartridge 10 and the main body 50. However, it is not limited to this, and at least a portion of the main body 50 may be inserted into the interior of the cartridge 10 to connect the cartridge 10 and the main body 50. The cartridge 10 and the main body 50 are fastened together in various ways, such as screw fastening, magnetic fastening, snap-fit ​​fastening, or snap-fit ​​fastening.

[0098] In one embodiment, the cartridge 10 may include at least a portion of a storage tank 30, a transmission member 32, and a vibrator assembly 33, and may also include a housing 20 for housing these components inside.

[0099] In one embodiment, the housing 20 may form the exterior of the cartridge 10 and may house at least some of the components for driving the aerosol generator 100 inside.

[0100] In one embodiment, the structure and shape of the housing 20 can be embodied in various ways, for example, as shown in Figure 2, and may be formed in a columnar or stick shape. The housing 20 includes a mouthpiece 23 and an aerosol channel 27.

[0101] In one embodiment, the mouthpiece 23 may be directly or indirectly connected to the user's body of the aerosol generator 100. The mouthpiece 23 includes an inlet 25 that is connected to the inside of the cartridge 10, specifically to the aerosol channel 27.

[0102] For example, the user places their mouth in contact with the mouthpiece 23 and inhales the aerosol generated by the aerosol generator 100. When the user inhales through the mouthpiece 23, the pressure in the inlet 25 and the aerosol channel 27 decreases, and the aerosol inside the cartridge 10 passes through the aerosol channel 27 and the inlet 25 and is transmitted to the user.

[0103] In one embodiment, the storage tank 30 is located in the internal space of the housing 20 and contains the aerosol-generating material. For example, the storage tank 30 may contain and store the aerosol-generating material, provide the aerosol-generating material to other components (e.g., the transmission member 32), or be supplied with the aerosol-generating material from an external source.

[0104] In one embodiment, the aerosol-generating substance may be a substance in various states such as liquid, solid, gas, or gel, or a substance in which parts of these states are mixed.

[0105] In one embodiment, the aerosol-generating substance may be a liquid containing volatile tobacco flavor components and tobacco-containing materials. For example, the aerosol-generating substance may contain at least a portion of water, solvent, ethanol, plant extracts, fragrances, flavorings, and a vitamin mixture. Alternatively, the aerosol-generating substance may contain at least a portion of menthol, peppermint, spearmint oil, and fruit flavor components.

[0106] In one embodiment, the transmission member 32 may transmit aerosol-generating material from the storage tank 30. The transmission member 32 may be directly or indirectly connected to the storage tank 30, and at least a portion of it may face the aerosol channel 27. The transmission member 32 may include at least a portion of cotton, ceramic, glass, and porous material, or it may structurally include a channel through which the aerosol-generating material flows. For example, the transmission member 32 may be a wick made of a hygroscopic or porous material.

[0107] In one embodiment, the transducer assembly 33 may be located inside the housing 20 and generate vibrations with a transmission member 32. The transducer assembly 33 includes a transducer 35 and a cartridge board 37 that controls the driving of the transducer 35.

[0108] For example, the transducer assembly 33, or the transducer assembly 33 and other components (e.g., a portion of the housing 20 and / or the transmission member 32), may constitute an atomizer. A specific structure of the transducer assembly 33 according to one embodiment will be described in detail from Figure 5a onward.

[0109] In one embodiment, the transducer assembly 33 can generate vibrations with a relatively short period or generate ultrasonic vibrations. For example, the frequency of the ultrasonic vibrations is approximately 100 kHz to 3.5 MHz. The vibrations of the transducer assembly 33 cause the aerosol-generating substance transmitted from the storage tank 30 to the transmission member 32 to vaporize and / or atomize into an aerosol.

[0110] In one embodiment, the main body 50 can house a control unit (for example, the control unit 110 in Figure 1) that controls the drive of the aerosol generator 100, a battery (for example, the battery in Figure 1), and other components (for example, at least a part of the detection unit 120, output unit 130, memory 170, and communication unit 180 in Figure 1).

[0111] In one embodiment, the main body 50 may be electrically or communicatively connected to the cartridge board 37 to supply data and / or power. In Figure 2, the control unit 110 and the cartridge board 37 are shown separately, but this is illustrative and not limited thereto. For example, the cartridge board 37 is included as part of the control unit 110, and the main body 50 further includes a main body board (e.g., the main body board 272 in Figure 5a) which is another component of the control unit 110.

[0112] Figure 3a is a perspective view of the aerosol generator 200 according to one embodiment, and Figure 3b is a perspective view of the aerosol generator 200 according to one embodiment. Specifically, Figure 3a shows the mouthpiece 223 of the aerosol generator 200 in a closed state, and Figure 3b shows the mouthpiece 223 of the aerosol generator 200 in an open state.

[0113] Referring to Figures 3a and 3b, an aerosol generator 200 according to one embodiment (for example, the aerosol generator 100 in Figure 1 or Figure 2) may include at least a part of the cartridge 210 (for example, the cartridge 10 in Figure 2) and the main body 250 (for example, the main body 50 in Figure 2).

[0114] In one embodiment, the aerosol generator 200 and its configuration shown in Figure 3a and subsequent figures are illustrative examples of one of the achievable embodiments of the aerosol generator 200 described in detail with reference to Figures 1 and 2. Actual implementation is not limited to this, and the aerosol generator 200 can be implemented in various structures and shapes. In describing the aerosol generator 200 below, any content that overlaps with the above description will be omitted.

[0115] In one embodiment, the main body 250 includes a first body 250a and a second body 250b. The first body 250a and the second body 250b are fastened together so as to be mutually fixed, and each of the first body 250a and the second body 250b can house and protect the internal components of the aerosol generator 200.

[0116] In one embodiment, the first body 250a includes a cartridge fastening region 255, and when a cartridge 210 is fastened to the cartridge fastening region 255, the cartridge 210 can be supported. For example, the cartridge fastening region 255 may be formed open to one side of the first body 250a (e.g., the +z direction), and the cartridge 210 may be fastened in such a way that it is inserted into the cartridge fastening region 255.

[0117] In one embodiment, the second body 250b may be fastened to the first body 250a and may be an area for the user to grip the aerosol generator 200. Although not shown, the second body 250b may house at least some components of a temperature sensor (e.g., the temperature sensor 122 in Figure 1) and a circuit board (e.g., the control unit 110 in Figure 1 or 2). In the drawings, the second body 250b is shown to have a substantially circular or polygonal shape, but is not limited thereto in actual implementation, and may be implemented as, for example, a columnar or stick shape.

[0118] In one embodiment, the cartridge 210 may include a mouthpiece 223. The mouthpiece 223 may be rotated or tilted with respect to a pivot axis, thereby selectively exposing the suction port 225 of the mouthpiece 223 (e.g., suction port 25 in Figure 2).

[0119] For example, as shown in Figure 3a, when the user is not using the aerosol generator 200 or when it is in storage, the mouthpiece 223 is located inside the cartridge fastening area 255, and the suction port 225 does not need to be exposed to the outside of the aerosol generator 200.

[0120] For example, as shown in Figure 3b, the user can rotate or tilt the mouthpiece 223 to use the aerosol generator 200, so that the suction port 225 is exposed to the outside of the aerosol generator 200.

[0121] As shown in Figures 3a and 3b, the aerosol generator 200 can prevent external foreign matter from flowing into the cartridge 210 through the suction port 225 by covering the suction port 225 as needed, thereby preventing contamination of the suction port 225. Alternatively, by blocking the suction port 225, it is possible to prevent aerosols or a portion of the aerosol-generating material from flowing out of the cartridge 210 to the outside of the aerosol generator 200.

[0122] However, the driving mechanism of the mouthpiece 223 in Figures 3a and 3b is illustrative and is not limited to this in actual implementation, and may be implemented in various ways. For example, the main body 250 or cartridge 210 may include a separate door to selectively expose the suction port 225 of the cartridge 210.

[0123] Figure 4 is an exploded perspective view of a cartridge 210 according to one embodiment.

[0124] Referring to Figure 4, in one embodiment, the cartridge 210 includes a cartridge body 211 and a mouthpiece 223.

[0125] In one embodiment, the cartridge body 211 includes at least a portion of the housing 205, the core 235, and the transducer assembly 240.

[0126] In one embodiment, the mouthpiece 223 may be movably coupled or connected to the cartridge body 211. The components of the cartridge 210 according to one embodiment are not limited to the examples given above, and components may be added or some components omitted depending on the embodiment.

[0127] In one embodiment, the housing 205 may form the overall appearance of the cartridge 210 while also forming an internal space capable of accommodating components of the cartridge 210 (e.g., a storage tank 230, a core 235, and at least a portion of the transducer assembly 240).

[0128] In one embodiment, the structure and shape of the housing 205 may be represented in various ways. For example, the housing 205 may be formed in a columnar or stick shape, but is not limited thereto. Although the drawings show only an embodiment in which the housing 205 of the cartridge 210 is generally rectangular prism-shaped, in other embodiments (not shown) the housing 205 may be generally cylindrical and may be formed in a polygonal prism shape other than a rectangular prism (e.g., triangular prism, pentagonal prism).

[0129] In one embodiment, the housing 205 includes a first housing 205a, a second housing 205b connected to one area of ​​the first housing 205a, and a third housing 205c connected to another area of ​​the first housing 205a.

[0130] For example, the second housing 205b may be coupled to a region located at the lower end of the first housing 205a (e.g., in the -z direction), and an internal space may be formed between the first housing 205a and the second housing 205b where components of the cartridge 210 can be arranged.

[0131] In one embodiment, the third housing 205c may be coupled to a region located at the upper end of the first housing 205a (for example, in the +z direction), and at least a portion of the mouthpiece 223 may be positioned on one side of the third housing 205c.

[0132] In one embodiment, the first housing 205a and the second housing 205b may, by being coupled to each other, form an aerosol channel 224 through which airflow (e.g., air, aerosol) moves inside the cartridge body 211. For example, the first housing 205a forms part of the aerosol channel 224, and the second housing 205b forms the remaining part of the aerosol channel 224.

[0133] In one embodiment, the first housing 205a and the second housing 205b may be joined together to form an internal space, which may house or arrange various components necessary for the operation of the cartridge 210, such as the oscillator assembly 240 and the core 235.

[0134] In one embodiment, the first housing 205a and the second housing 205b protect components housed in their internal spaces, and the third housing 205c may protect the mouthpiece 223 and other components coupled to or connected to the mouthpiece 223. The housing 205 forms at least a portion of the aerosol channel 224, or the structure of at least a portion of the housing 205 functions as the inner wall of the aerosol channel 224.

[0135] In one embodiment, the housing 205 may include a sensor hole 207. The sensor hole 207 may be formed in a portion of the second housing 205b of the housing 205. For example, the sensor hole 207 may be located on the lower end surface of the second housing 205b where the cartridge 210 is coupled to the main body 250. The sensor hole 207 may be formed in a position opposite the temperature sensor (for example, the temperature sensor 271 in Figure 5a). The sensor hole 207 will be described in Figure 5a and subsequent figures.

[0136] In one embodiment, the mouthpiece 223 is the part that comes into contact with the user's oral cavity, and the mouthpiece 223 is positioned or coupled to a region of the housing 205. For example, the mouthpiece 223 is connected to a third housing 205c.

[0137] In one embodiment, the mouthpiece 223 is movable between an open position and a closed position. The cartridge 210 further includes an elastic body 223a that provides elastic force to the mouthpiece 223. For example, the elastic body 223a may elastically support the mouthpiece 223 toward the open position.

[0138] In one embodiment, the elastic body 223a is positioned around or on the axis of rotation of the mouthpiece 223. The mouthpiece 223 moves from a closed position to an open position due to the elastic force of the elastic body 223a. The elastic body 223a may be made of a metal material (for example, SUS).

[0139] In one embodiment, the mouthpiece 223 is rotatable about an axis of rotation, and the elastic body 223a may be a torsion spring located on the axis of rotation of the mouthpiece 223. The elastic body 223a is in a state where its deformation is relatively large when the mouthpiece 223 is in a closed position, and in a state where its deformation is relatively small when the mouthpiece 223 is in an open position. This provides the mouthpiece 223 with an elastic force that is deflected to open from the closed position to the open position.

[0140] In one embodiment, the mouthpiece 223 includes a suction port 225 for discharging aerosol generated inside the cartridge 210 to the outside of the cartridge 210. For example, the suction port 225 may have one side connected to the outside and the other side connected to an aerosol channel 224 in an open position. The user can bring their oral cavity into contact with the mouthpiece 223 and be supplied with aerosol to be discharged to the outside through the suction port 225 of the mouthpiece 223.

[0141] In one embodiment, the mouthpiece 223 is rotatably or tiltably coupled to the third housing 205c together with a support portion 223b. The support portion 223b is positioned between the mouthpiece 223 and the third housing 205c and can surround at least a portion of the other side of the mouthpiece 223.

[0142] In one embodiment, the mouthpiece 223, the support 223b, and the third housing 205c are connected to each other by a pivot axis. This not only firmly connects the mouthpiece 223 to the third housing 205c, but also allows it to rotate relative to the third housing 205c and move between an open position and a closed position.

[0143] In one embodiment, the aerosol atomized by the transducer assembly 240 is discharged to the outside of the cartridge 210 via the aerosol channel 224 and supplied to the user. For example, the aerosol generated by the transducer of the transducer assembly 240 (e.g., transducer 241 in Figure 5b) flows along the aerosol channel 224, which is formed to connect or communicate with the atomization space (e.g., atomization space 265 in Figure 5a) and the suction port 225 of the mouthpiece 223, and is then discharged to the outside of the cartridge 210 via the suction port 225.

[0144] In one embodiment, the aerosol channel 224 is connected to the mouthpiece 223 along the internal structure of the second housing 205b and the first housing 205a. For example, the airflow moving in the positive direction along the aerosol channel 224 may move sequentially in a certain direction (e.g., sequentially in the +z direction, across the z axis, in the -z direction, across the z axis, and in the +z direction).

[0145] In one embodiment, the suction port 225 refers to a passage inside the mouthpiece 223. The suction port 225 is connected to the aerosol passage 224 when the mouthpiece 223 is in the open position. The suction port 225 is disconnected from the aerosol passage 224 when the mouthpiece 223 is in the closed position.

[0146] In one embodiment, the storage tank 230 is located inside the first housing 205a, and the aerosol-generating substance is stored inside the storage tank 230. For example, the storage tank 230 may store a liquid aerosol-generating substance, but is not limited to this.

[0147] In one embodiment, the core 235 is located between the storage tank 230 and the transducer 241 of the transducer assembly 240. The core 235 includes a transmission member 235a and an absorber 235b.

[0148] In one embodiment, the transmission member 235a can be in contact with the reinforcing member 260, and the absorber 235b can be provided between the transmission member 235a and the vibrator 241. The transmission member 235a includes the reinforcing member 260 and, for example, a core hole communicating with an opening in the reinforcing member 260, and the absorber 235b can be positioned to face the atomization space 265 through the core hole.

[0149] In one embodiment, the aerosol-generating material stored in the storage tank 230 is supplied to the transducer assembly 240 through the transmission member 235a. The transmission member 235a receives the aerosol-generating material from the storage tank 230 and transmits the supplied aerosol-generating material to the transducer 241 or absorber 235b, or the transmission member 235a receives ultrasonic vibrations from the transducer 241 and atomizes the aerosol-generating material. For example, the transmission member 235a can absorb the aerosol-generating material from the storage tank 230, and the aerosol-generating material absorbed by the transmission member 235a can be transmitted to the transducer assembly 240.

[0150] In one embodiment, the cartridge 210 includes an absorber 235b that transmits the absorbed aerosol-generating material to the transducer assembly 240. The absorber 235b may be positioned to cover at least a portion of the transducer 241 of the transducer assembly 240 where the aerosol is generated, and the aerosol-generating material is transmitted from the transmission member 235a and absorbed and atomized at least a portion of it.

[0151] In one embodiment, the absorbent 235b may be made of a material capable of absorbing aerosol-generating substances. For example, the absorbent 235b may contain at least one of the following materials: SPL 30(H), SPL 50(H)V, NP100(V8), SPL60(FC), and melamine.

[0152] In one embodiment, by further including an absorbent 235b in the cartridge 210, the aerosol-generating substance is absorbed not only by the transmission member 235a but also by the absorbent 235b, thereby improving the amount of aerosol-generating substance absorbed.

[0153] In one embodiment, the transmission member 235a may include a material having an even faster absorption rate of aerosol-generating material than the absorber 235b. For example, if the transmission member 235a has a faster absorption rate than the absorber 235b, the aerosol-generating material transmitted to the absorber 235b by the transmission member 235a can be adjusted to be supplied to the transducer 241 at a uniform rate by the absorber 235b, which has a relatively slow absorption rate. This prevents too much aerosol-generating material from coming into contact with the transducer 241.

[0154] In one embodiment, the absorber 235b is positioned to cover at least a portion of the vibrator 241, so that the absorber 235b functions as a physical barrier to prevent "splatter," which occurs when particles that have not been sufficiently atomized during the aerosol generation process are immediately discharged outside the aerosol generator 200. Here, "splatter" means that particles of aerosol-generating material that have not been sufficiently atomized and are relatively large in size are discharged outside the cartridge 210. By further including the absorber 235b in the cartridge 210, the likelihood of splatter is reduced, and the user's smoking satisfaction can be improved.

[0155] In one embodiment, the absorber 235b is located between one surface of the transducer 241 on which aerosol is generated and the transmission member 235a, and can transmit the aerosol supplied to the transmission member 235a to the transducer 241.

[0156] For example, one region of the absorber 235b may be in contact with one region of the transmission member 235a facing in one direction (e.g., the -z direction), and the other region of the absorber 235b may be in contact with one region of the oscillator 241 of the oscillator assembly 240 facing in one direction (e.g., the +z direction). That is, the absorber 235b is located on the upper end surface of the oscillator 241 (e.g., the surface in the +z direction or the first surface 241a in Figure 5b), and can supply the aerosol-generating material absorbed by the transmission member 235a to the oscillator assembly 240.

[0157] In one embodiment, the transmission member 235a, the absorber 235b, and the transducer assembly 240 are arranged sequentially along the longitudinal direction (e.g., the z-axis direction) of the cartridge 210 or housing 205, and the absorber 235b and the transmission member 235a may be stacked sequentially on the transducer 241.

[0158] Through the arrangement described above, at least a portion of the aerosol-generating material supplied from the storage tank 230 to the transmission member 235a moves to the absorber 235b that is in contact with the transmission member 235a, and the aerosol-generating material that has moved to the absorber 235b moves along the absorber 235b and reaches the region adjacent to the oscillator assembly 240.

[0159] In one embodiment, the aerosol-generating substance is stably transmitted to the oscillator assembly 240, which can continuously generate a uniform amount of aerosol, and through the above-described arrangement, the transmission member 235a and absorber 235b embody a physical double barrier that prevents the aforementioned liquid splashing.

[0160] In one embodiment, the drawings show only an embodiment that includes one transmission member 235a and one absorbent 235b, but cartridges 210 in other embodiments may further include at least two or more transmission members 235a and absorbent 235b, or the transmission member 235a and absorbent 235b may be embodied as a single body.

[0161] For example, the absorber 235b may be a separate component of the cartridge 210 connected to the transmission member 235a, or the transmission member 235a and the absorber 235b may be interconnected or joined together, or they may be an integrated component, and are not limited to these.

[0162] In one embodiment, the cartridge 210 further includes a support plate 246 for grounding the cartridge substrate 245 or for firmly connecting the cartridge substrate 245 to the second housing 205b.

[0163] In one embodiment, the transducer assembly 240 may include at least a portion of the transducer 241, the first electrode body 243, the second electrode body 244, the support structure 247, the support plate 246, and the cartridge substrate 245.

[0164] In one embodiment, the vibrator assembly 240 can generate vibrations in the transmission member 235a to atomize the aerosol-generating substance.

[0165] In one embodiment, the vibrator 241 can generate vibrations at the transmission member 235a, atomizing a liquid-phase aerosol-generating substance to produce an aerosol. The vibrator 241 includes a first surface 241a facing the transmission member 235a of the core 235, and a second surface 241b opposite to the first surface 241a.

[0166] In one embodiment, the oscillator 241 may include a piezoelectric ceramic. A piezoelectric ceramic is a functional material that generates electricity when a force is applied and generates force when electricity is applied, and mutually converts electricity and force. For example, the oscillator 241 generates short-period vibrations in response to applied electricity, and these vibrations can vaporize and / or atomize aerosol-generating substances.

[0167] In one embodiment, the transducer 241 can generate ultrasonic vibrations. The frequency of the ultrasonic vibrations generated by the transducer 241 may be about 100 kHz to 10 MHz, preferably about 100 kHz to 3.5 MHz.

[0168] In one embodiment, the transducer 241 can vibrate along the longitudinal direction (e.g., the z-axis direction) of the cartridge 210 or housing 205 by generating ultrasonic vibrations in the corresponding frequency band. However, the direction in which the transducer 241 vibrates in one embodiment of this document is not limited thereto, and the direction in which the transducer vibrates may be changed to various directions (e.g., any one of the x-axis, y-axis, and z-axis directions, or a combination thereof).

[0169] In one embodiment, the transducer 241 atomizes the aerosol-generating substance using an ultrasonic method, enabling the generation of aerosols at a relatively lower temperature compared to methods that heat the aerosol-generating substance. For example, in methods that use a heater to heat the aerosol-generating substance, the aerosol-generating substance may be unintentionally heated to a temperature of 200 degrees Celsius or higher, causing the user to perceive a burnt taste from the aerosol.

[0170] In one embodiment of this document, the cartridge 210 atomizes the aerosol-generating substance using an ultrasonic method, enabling the generation of aerosols at a relatively lower temperature range of approximately 100°C to 160°C compared to heating with a heater. This reduces the degree to which the user perceives a burnt taste from the aerosol, thereby improving the user's smoking satisfaction.

[0171] In one embodiment, the transducer 241 can be electrically connected to an external power source via a cartridge substrate 245, and ultrasonic vibrations can be generated by power supplied from the external power source. For example, the transducer 241 is electrically connected to a cartridge substrate 245 located inside the cartridge 210, and the cartridge substrate 245 is electrically connected to the main body 250, so that the transducer 241 can be powered by a battery (for example, battery 140 in Figure 1 or Figure 2).

[0172] In one embodiment, the aerosol can be generated in an atomizing space (e.g., atomizing space 265 in Figure 5a) located on the first surface 241a of the transducer 241 and communicating with the aerosol channel 224. When the user inhales into the open mouthpiece 223, the aerosol generated in the atomizing space 265 mixes with the outside air flowing in along the aerosol channel 224 and moves toward the inlet 225.

[0173] In one embodiment, the transducer 241 can be electrically connected to the cartridge substrate 245 via the first electrode body 243 and the second electrode body 244.

[0174] In one embodiment, the first electrode body 243 includes a conductive material (e.g., metal) and is in contact with the first surface 241a of the resonator 241, thereby electrically connecting the resonator 241 and the cartridge substrate 245.

[0175] In one embodiment, the first electrode body 243 is cylindrical in shape so as to accommodate at least a portion of the outer circumferential surface of the resonator 241. An opening may be formed in a portion of the first electrode body 243 so that at least a portion of the resonator 241 (for example, the first surface 241a) is exposed to the outside of the first electrode body 243.

[0176] For example, a portion of the first electrode body 243 (e.g., the upper portion) is positioned to surround at least one area of ​​the outer surface of the resonator 241 and to contact the resonator 241, while the other portion of the first electrode body 243 (e.g., the lower portion) is formed to extend from the portion toward the cartridge substrate 245 and to contact a region of the cartridge substrate 245. The above-described contact structure of the first electrode body 243 allows the resonator 241 to be electrically connected to the cartridge substrate 245.

[0177] In one embodiment, the first electrode body 243 has an opening, and at least a portion of the resonator 241 is exposed to the outside of the first electrode body 243. A portion of the first surface 241a of the resonator 241 that is exposed to the outside of the first electrode body 243 through the opening of the first electrode body 243 comes into contact with the transmission member 235a and / or absorber 235b, and can atomize the aerosol-generating material of the transmission member 235a and / or absorber 235b.

[0178] In one embodiment, the second electrode body 244 includes a conductive material and is placed on the second surface 241b of the resonator 241 or between the resonator 241 and the cartridge substrate 245, thereby electrically connecting the resonator 241 and the cartridge substrate 245.

[0179] For example, the second electrode body 244 can electrically connect the resonator 241 to the cartridge substrate 245 by having one end in contact with the second surface 241b of the resonator 241 and the other end in contact with a portion of the cartridge substrate 245 facing the resonator 241.

[0180] In one embodiment, the second electrode 244 contacts the second surface 241b of the resonator 241 and pressurizes the resonator 241 in the direction in which the first surface 241a of the resonator 241 faces (for example, the +z direction). The second electrode body 244 is elastic and can be compressed between the support structure 247 and the other surface of the resonator 241 to support the resonator 241.

[0181] In one embodiment, the second electrode body 244 includes an elastic conductive material and not only serves to electrically connect the resonator 241 and the cartridge substrate 245, but also provides an elastic force to the resonator 241 in the direction of the second surface 241b, thereby supporting the resonator 241.

[0182] For example, the second electrode body 244 may include a conductive spring, but the second electrode body 244 is not limited to the embodiments described above.

[0183] In one embodiment, the support plate 246 is positioned between the support structure 247 and the cartridge substrate 245, and at least a portion of it is fastened to the cartridge substrate 245, thereby supporting the support structure 247. The support plate 246 can reinforce the fastening force between the cartridge substrate 245 and the first electrode body 243.

[0184] In one embodiment, the support plate 246 may include an inclined region having a flat shape relative to a planar region. The planar region and the inclined region of the support plate 246 are formed integrally, and the inclined region is elastic so that a repulsive force acts when pressure is applied to bring the planar region and the inclined region closer together.

[0185] In one embodiment, the cartridge 210 is located between the second surface 241b of the transducer 241 and the cartridge substrate 245 and includes a support structure 247 that supports the second electrode body 244.

[0186] In one embodiment, the support structure 247 is positioned inside the first electrode body 243 and supports the oscillator 241. At least a portion of the support structure 247 may be surrounded by the first electrode body 243, and at least a portion of the support structure 247 may be coupled to the first electrode body 243 in a press-fit manner.

[0187] In one embodiment, the support structure 247 includes, for example, an elastic material (e.g., silicone, rubber) and is arranged to surround the outer circumferential surface of the second electrode body 244, thereby elastically supporting the second electrode body 244.

[0188] In one embodiment, one side of the vibrator 241 is supported by a first electrode body 243, and the other side of the vibrator 241 is supported by a support structure 247. The other side of the vibrator 241 that is in contact with the support structure 247 can be pressurized by the support structure 247 in a direction from the other side toward the one side. This prevents the vibrator 241 from moving out of position or being damaged due to vibrations generated when the vibrator 241 is operating.

[0189] In one embodiment, the cartridge substrate 245 can be placed inside the second housing 205b. For example, the cartridge substrate 245 may be placed at a distance from the transducer 241, or it may be electrically connected to the transducer 241 via the first electrode body 243 and the second electrode body 244. The cartridge substrate 245 may also be electrically connected to the internal configuration of the main body 250 of the aerosol generator 200 (for example, the main body substrate 272 in Figure 5a).

[0190] In one embodiment, the cartridge substrate 245 is electrically connected to the first electrode body 243 and the second electrode body 244 and can supply a signal to the resonator 241. The cartridge substrate 245 may be fastened to at least a portion of the part of the first electrode body 243 that surrounds the outer circumferential surface of the resonator 241.

[0191] In one embodiment, the cartridge substrate 245 is electrically connected to the transducer 241 by the first electrode body 243 and the second electrode body 244, and simultaneously electrically connected to the main body 250, so that the transducer 241 can be electrically connected to the external power supply of the cartridge 210 via the cartridge substrate 245 and receive power.

[0192] In one embodiment, the cartridge 210 may further include a reinforcing member 260 to prevent aerosol-generating material from leaking from the storage tank 230 and flowing into the aerosol channel 224.

[0193] For example, if at least a portion of the aerosol channel 224 is surrounded by the storage tank 230, aerosol-generating substances leaking from the storage tank 230 may enter the aerosol channel 224, potentially reducing the user's smoking satisfaction.

[0194] In one embodiment of this specification, the reinforcing member 260 can seal the gap around the liquid phase supply port of the storage tank 230 (for example, the gap between the liquid phase supply port and the transmission member 235a). As a result, in the cartridge 210 according to one embodiment, the reinforcing member 260 can prevent the aerosol-generating material from the storage tank 230 from leaking into the aerosol channel 224, thereby preventing a decrease in the user's smoking satisfaction.

[0195] In one embodiment, the reinforcing member 260 can prevent aerosol-generating material from the storage tank 230 from leaking into the aerosol channel 224. For example, the reinforcing member 260 may have a circular hollow shape. The reinforcing member 260 is fitted inside the first housing 205a and is in close contact with the outer wall of the storage tank 230.

[0196] In one embodiment, the reinforcing member 260 has a passage portion inside, which prevents aerosol-generating material from flowing from the storage tank 230 into the aerosol channel 224, and at the same time forms a part of the aerosol channel 224 through which the aerosol generated from the vibrator 241 moves.

[0197] In one embodiment, the reinforcing member 260 includes at least one hole that connects to the aerosol channel 224. For example, the reinforcing member 260 may include a second opening (for example, the second opening 262 in Figure 5a) on its upper surface (for example, the surface in the +z direction).

[0198] In one embodiment, the atomization space 265 is located on the first surface 241a of the transducer 241 facing the aerosol channel 224, and the atomization space 265 and the aerosol channel 224 can communicate at the top of the transducer 241. The cartridge 210 has a linear aerosol discharge path, and the generated aerosol is easily discharged to the outside of the cartridge 210.

[0199] In one embodiment, the second opening 262 is formed so that the aerosol generated in the atomization space 265 is moved to the aerosol channel 224. For example, the second opening 262 is formed in the reinforcing member 260 in the portion where the atomization space 265 faces the aerosol channel 224, and the aerosol generated in the atomization space 265 and flowing in one direction (e.g., the +z direction) can be moved towards the mouthpiece 223 through the second opening 262.

[0200] In one embodiment, the reinforcing member 260 includes an elastic material (e.g., rubber) that can absorb ultrasonic vibrations generated by the transducer 241. This minimizes the transmission of ultrasonic vibrations generated by the transducer 241 to the user via the housing 205 of the cartridge 210.

[0201] In one embodiment, the reinforcing member 260 is located above the transmission member 235a and presses the transmission member 235a toward the vibrator 241.

[0202] In one embodiment, the cartridge 210 may further include a waterproof member 249 for holding the transmission member 235a and / or the transducer 241 inside the first housing 205a.

[0203] In one embodiment, the waterproof member 249 is arranged to surround at least a portion of the outer circumferential surface of the transmission member 235a, the absorber 235b, and / or the transducer 241, and can accommodate the transmission member 235a, the absorber 235b, and / or the transducer 241.

[0204] In one embodiment, the waterproof member 249 is positioned between the first housing 205a and the second housing 205b, and the transmission member 235a, absorber 235b and / or vibrator 241 may be held or fixed in the region between the first housing 205a and the second housing 205b.

[0205] In one embodiment, the waterproof member 249 may be coupled to the first housing 205a in such a way that at least a portion of the waterproof member 249 is press-fitted into the first housing 205a; however, the method of coupling the first housing 205a and the waterproof member 249 is not limited to the above example. As another example, the first housing 205a and the waterproof member 249 may also be coupled by at least one of the following methods: snap-fit, screw coupling, or magnetic coupling.

[0206] In one embodiment, the waterproof member 249 includes a material (e.g., silicone, rubber) that has a predetermined rigidity and is waterproof, and not only fixes the transmission member 235a and the transducer 241 to the first housing 205a, but can also prevent leakage of aerosol-generating material from the storage tank 230. For example, the waterproof member 249 can prevent leakage of aerosol-generating material by sealing the area of ​​the storage tank 230 adjacent to the transmission member 235a or the transducer 241.

[0207] In one embodiment, the waterproof member 249, like the reinforcing member 260, includes an elastic material (e.g., rubber) and can absorb ultrasonic vibrations generated from the transducer 241.

[0208] In one embodiment, the waterproof member 249 includes a fixing projection 249a that is formed to protrude in the direction of the core 235. The fixing projection 249a may be inserted into a fixing groove 235c formed in the transmission member 235a of the core 235, and the fixing projection 249a may support or fix the core 235.

[0209] In one embodiment, the cartridge 210 may further include a first seal 236 for maintaining the connection between the first housing 205a and the third housing 205c and for sealing the storage tank 230.

[0210] In one embodiment, the first seal 236 can be positioned between the first housing 205a and the third housing 205c. For example, the first seal 236 can be coupled to the upper end of the first housing 205a and to the lower end of the third housing 205c, thereby firmly maintaining the connection between the first housing 205a and the third housing 205c.

[0211] In one embodiment, the first seal 236 may include a structure that selectively seals the storage tank 230 without sealing the aerosol channel 224. For example, the first seal 236 may have a hole formed in the portion where the aerosol channel 224 is located, and an air channel 270 formed in the portion where the storage tank 230 is located, relative to the state in which it is coupled to the upper end of the first housing 205a. The first seal 236 can separate the storage tank 230 and the aerosol channel 224 at the upper end of the first housing 205a without blocking the aerosol channel 224.

[0212] In one embodiment, the air passage 270 can connect the storage tank 230 to the outside. For example, one side of the air passage 270 can connect to the storage tank 230, and the other side of the air passage 270 can connect to the outside of the cartridge 210 or to the outside of the aerosol generator (for example, the aerosol generator 200 in Figures 3a and 3b). The air passage 270 is opened and closed by the mouthpiece 223.

[0213] In one embodiment, the cartridge 210 may further include a second seal 238 that is coupled to the third housing 205c to seal around the aerosol channel 224. The second seal 238 may be coupled to the upper end of the third housing 205c. The second seal 238 can seal around the portion where the aerosol channel 224 and the intake port 225 are connected, while including a hole sized to correspond to the aerosol channel 224 so as not to block the aerosol channel 224.

[0214] In one embodiment, the cartridge 210 includes both the first seal 236 and the second seal 238.

[0215] In one embodiment, the first seal 236 and the second seal 238 are coupled to the upper and lower ends of the third housing 205c, respectively, and at least portions of the first seal 236 and the second seal 238 may be partially coupled inside the third housing 205c. This further strengthens the coupling between the first housing 205a and the third housing 205c via the first seal 236 and the second seal 238.

[0216] In one embodiment, the first seal 236 and the second seal 238 may be joined in an interference fit manner to the first housing 205a and / or the third housing 205c, but the method of joining the first seal 236 and the second seal 238 is not limited to the examples given above.

[0217] In one embodiment, the first seal 236 and the second seal 238 may comprise a material having predetermined rigidity and waterproofness (e.g., silicone), be firmly bonded to the first housing 205a and / or the third housing 205c, and function as part of the inner wall of the aerosol channel 224.

[0218] For example, during the process in which the aerosol-generating material is atomized by the oscillator 241, some of the aerosol-generating material may not be atomized sufficiently, resulting in the formation of relatively large droplets. Alternatively, some of the atomized aerosol may liquefy inside the airflow passage, forming droplets. These droplets may block the aerosol channel 224, leak to the outside of the cartridge 210 via other routes (e.g., the inlet 251 in Figure 5a), or leak to the outside of the mouthpiece 223 via the intake port 225, reducing user convenience and smoking satisfaction. The first seal 236 and the second seal 238 prevent this, providing the user with convenience and smoking satisfaction.

[0219] Figure 5a is a cross-sectional view of an aerosol generator 200 according to one embodiment, and Figure 5b is an enlarged cross-sectional view of the aerosol generator 200 according to one embodiment. Specifically, Figure 5b is an enlarged view of area A shown in Figure 5a.

[0220] Referring to Figures 5a and 5b, the aerosol generator 200 of one embodiment includes a temperature sensor 271 and a lens 273.

[0221] The cartridge 210 inserted into the aerosol generator 200 described below may be the cartridge 210 shown in Figure 4, but is not limited to this. In the following description of the aerosol generator 200 with the cartridge 210 inserted, any information that overlaps with the above description will be omitted.

[0222] In one embodiment, the cartridge 210 can be detachably coupled to a cartridge fastening region 255 of the main body 250. The cartridge fastening region 255 may be a part of the main body 250 to which the cartridge 210 is coupled. The fixing member 255a can hold or fix the mouthpiece 223 in the closed position.

[0223] In one embodiment, the cartridge fastening region 255 can accommodate at least a portion of the cartridge 210. For example, the cartridge fastening region 255 may have a shape corresponding to at least a portion of the cartridge 210 (e.g., a portion of the housing 205) so that at least a portion of the mouthpiece 223 and the cartridge body (e.g., the cartridge body 221 in Figure 4) of the cartridge 210 can be accommodated or inserted.

[0224] In one embodiment, at least one region of the cartridge body 221 of the cartridge 210 includes a first magnetic material (not shown), and at least one region of the cartridge fastening region 255 of the main body 250 includes a second magnetic material (not shown). For example, the first magnetic material (not shown) is located on the lower surface of the cartridge body 221, and the second magnetic material (not shown) is located on the bottom surface of the cartridge fastening region 255 of the main body 250 that faces the lower surface of the inserted cartridge body 221. This allows the cartridge 210, once inserted to a predetermined position in the cartridge fastening region 255, to be coupled by magnetic force.

[0225] In one embodiment, the aerosol generator 200 includes a fixing member 255a for holding the mouthpiece 223 in a specific position. For example, the main body 250 may include a fixing member 255a for holding the closed mouthpiece 223 in the closed position. The fixing member 255a may be located in a portion of the cartridge fastening area 255 that houses the mouthpiece 223 in the closed position.

[0226] In one embodiment, when the mouthpiece 223 is closed, the user can apply an external force to move the mouthpiece 223 from the open position to the closed position. Once the mouthpiece 223 has moved to the closed position, the fixing member 255a may provide a holding force to the mouthpiece 223 to hold it in the closed position. For example, the fixing member 255a may provide a magnetic, elastic, and / or frictional force to one end of the mouthpiece 223 to hold it in the closed position.

[0227] In one embodiment, when the mouthpiece 223 is opened, the user can apply an external force to the mouthpiece 223 so that the mouthpiece 223 moves from the closed position to the open position. For example, if the user applies pressure to the other side of the mouthpiece 223 with a force greater than a predetermined amount, the mouthpiece 223 is separated from the fixing member 255a and rotates from the closed position to the open position.

[0228] In one embodiment, the fixing member 255a and one end of the mouthpiece 223 each contain magnetic materials having opposite polarities. As a result, when one end of the mouthpiece 223 approaches the closed position by a predetermined distance, it is pulled by magnetic force and held in the closed position.

[0229] In one embodiment, the aerosol generator 200 may further include an inhalation detection sensor (not shown). The inhalation detection sensor (not shown) can detect changes in the internal pressure or airflow of the aerosol generator 200 and can detect whether or not the user is inhaling the aerosol generator 200.

[0230] In one embodiment, the suction detection sensor (not shown) may be located either in the cartridge 210 or the main body 250. Since the cartridge 210 is a consumable item that is replaced when all the aerosol-generating material stored inside is consumed, it is preferable that the suction detection sensor (not shown) be located in the main body 250.

[0231] In one embodiment, a suction detection sensor (not shown) may be located adjacent to the cartridge fastening region 255 of the main body 250. For example, the suction detection sensor (not shown) may be located in a region of the cartridge fastening region 255 adjacent to the outer circumferential surface of the cartridge 210 coupled to the main body 250. In another example, the suction detection sensor (not shown) may be located in a region of the main body 250 facing the outer circumferential surface of the housing 205 of the cartridge 210 coupled to the main body 250.

[0232] In one embodiment, external air flows into the aerosol generator 200 through a minute gap between the coupled main body 250 and cartridge 210. By positioning an intake detection sensor (not shown) adjacent to the area through which the external air flows, pressure changes or airflow within the main body 250 can be detected more accurately.

[0233] In one embodiment, the main body 250 may include at least one inlet 251 through which external air from the main body 250 flows into the main body 250 and the cartridge 210. The inlet 251 may communicate with the interior of the cartridge 210 through at least one opening (e.g., a sensor hole 207) formed in the cartridge 210.

[0234] In one embodiment, the reinforcing member 260 includes a first opening 261, an atomizing space 265, and a second opening 262. The first opening 261 may be formed on the lower or bottom surface of the reinforcing member 260. The first opening 261 may be formed to open toward the transmission member 235a and / or the transducer 241 of the core 235. The reinforcing member 260 may communicate with the atomizing space 265 from the core 235 through the first opening 261. The second opening 262 is formed between the atomizing space 265 and the aerosol channel 224, and the aerosol generated in the atomizing space 265 is transmitted through the second opening 262 to the aerosol channel 224.

[0235] In one embodiment, the airflow can move in the positive direction from the inlet 251 through the atomizing space 265 of the reinforcing member 260 toward the intake port 225. In this case, “positive direction” means the direction in which the airflow moves when the user inhales the mouthpiece 223. For example, the positive direction means the direction from the inlet 251 toward the atomizing space 265 and the direction from the atomizing space 265 toward the intake port 225.

[0236] In one embodiment, a lens 273 may be positioned on one surface (e.g., the bottom surface) of the cartridge fastening area 255. In one embodiment, the lens 273 may be positioned so as to face a portion of the cartridge 210 (e.g., the sensor hole 207 of the cartridge 210) when the cartridge 210 is coupled to it.

[0237] In one embodiment, the temperature sensor 271 may be positioned in the main body 250 so as to face the cartridge fastening area 255. The temperature sensor 271 may be an infrared sensor.

[0238] For example, the temperature sensor 271 may include a light-emitting unit that emits infrared rays and a light-receiving unit that detects infrared rays reflected back from the target object. The temperature sensor 271 can detect the temperature of the target object via the amount of light detected by the light-receiving unit.

[0239] For example, the temperature sensor 271 of one embodiment may not include a light-emitting unit but may include a light-receiving unit. The light-receiving unit can detect the temperature of an object via the wavelength of light emitted and / or reflected from the object. However, this is an illustrative description of the driving of the temperature sensor 271 of the infrared sensor of one embodiment and is not limited to this in actual implementation, and can be implemented in various ways.

[0240] In one embodiment, the temperature sensor 271 may be connected to the main board 272, or it may be mounted or arranged on the main board 272. The main board 272 may be located inside the main body 250 and can control the overall operation of the aerosol generator 200.

[0241] In one embodiment, the main board 272 may be the control unit of the aerosol generator 200 (for example, the control unit 110 in Figure 1 or Figure 2) itself, or a part of it. For example, the control unit 110 may include the cartridge board 245 and the main board 272. The cartridge board 245 and the main board 272 may be connected to each other electrically and / or communicatively.

[0242] In one embodiment, the main board 272 is connected to the inside of the cartridge body 221 of the cartridge 210 via a cable or wire, and is connected to the cartridge board 245 of the cartridge 210. Since the cartridge board 245 of the cartridge 210 is in electrical contact with the vibrator 241, the vibrator 241 may be electrically connected to the main body 250 via the cartridge board 245. The vibrator 241 may be driven by the main board 272, or the vibrator 241 may be powered by the battery of the main body 250 (for example, the battery 140 in Figure 1 or Figure 2).

[0243] In one embodiment, the temperature sensor 271 can detect the temperature of the second surface 241b of the transducer 241. The transducer 241 generates heat by being driven and vibrating, and if the transducer 241 overheats, the transducer 241 or surrounding components may be damaged, or the performance of the transducer 241 may deteriorate. The temperature sensor 271 substantially directly measures the temperature of the second surface 241b of the transducer 241, and based on the detection result, the control unit can control the driving of the transducer 241.

[0244] In one embodiment, when the transducer 241 is heated, the central region of the second surface 241b of the transducer 241 changes temperature first. To enable the temperature sensor 271 to detect the temperature of the central region of the second surface 241b of the transducer 241, obstacles between the temperature sensor 271 and the transducer 241 can be eliminated or minimized, the path between the temperature sensor 271 and the transducer 241 can be shortened, and / or the path of light between the temperature sensor 271 and the transducer 241 can be controlled. As a result, the temperature sensor 271 can quickly and accurately detect temperature changes in the transducer 241.

[0245] In one embodiment, the temperature sensor 271, which is an infrared sensor, exhibits reduced accuracy in detection results when the distance to the target object is large, making it difficult to detect rapid temperature changes. In one embodiment, the lens 273 may be positioned between the sensor hole 207 and the temperature sensor 271. The lens 273 can widen the detection range of the temperature sensor 271 (or the field of view of the temperature sensor 271, which is an infrared sensor).

[0246] For example, the lens 273 may focus the light emitted from the temperature sensor 271 and control the optical path toward the second surface 241b of the oscillator 241. And / or, the lens 273 can focus the light reflected from the oscillator 241 (or the light emitted by the temperature sensor 271 that is reflected back by the oscillator 241) and control the optical path toward the temperature sensor 271. Through the lens 273, the temperature sensor 271 can accurately and quickly detect temperature changes of the oscillator 241.

[0247] Figure 6a is an enlarged cross-sectional view of an aerosol generator 200 according to one embodiment, and Figure 6b is an enlarged cross-sectional view of an aerosol generator 200 according to one embodiment.

[0248] Specifically, Figures 6a and 6b are enlarged views of area B shown in Figure 5a.

[0249] Referring to Figures 6a and 6b, the air passage 270 according to one embodiment can be opened and closed by the mouthpiece 223.

[0250] The following explanation will omit any content that overlaps with the above, and it goes without saying that in the aerosol generator 200, some configurations and structures may be replaced, added, or omitted to the extent that a person skilled in the art can easily understand them by referring to the following drawings and descriptions. Furthermore, the aerosol generator 200 may be combined with at least one configuration or feature of the above-described embodiment, unless it is technically clearly impossible.

[0251] In one embodiment, the air passage 270 can be opened in a direction toward the mouthpiece 223 from the inside of the storage tank 230. The air passage 270 can supply air to the inside of the storage tank 230 and control the pressure inside the storage tank 230.

[0252] For example, the aerosol generator 200 may be activated to move the aerosol-generating material inside the storage tank 230 to the core 235 and atomize it. As the amount of aerosol-generating material inside the storage tank 230 decreases, the internal pressure of the storage tank 230 gradually decreases. As the internal pressure of the storage tank 230 decreases, a backflow of air occurs in the core 235 from the atomization space 265 towards the storage tank 230. This backflow of air prevents the aerosol-generating material from being smoothly transferred to the core 235, reducing the efficiency of liquid phase transfer in the storage tank 230.

[0253] In one embodiment of this document, the air passage 270 can supply air to the inside of the storage tank 230 by selectively connecting the inside of the storage tank 230 to the outside of the storage tank 230. The air passage 270 can prevent a pressure drop inside the storage tank 230 caused by the operation of the aerosol generator 200 and improve the efficiency of liquid phase transfer in the storage tank 230.

[0254] In one embodiment, the air passage 270 may be opened or closed by the hinge drive of the mouthpiece 223. The mouthpiece 223 can be hinge-driven with respect to a hinge axis (e.g., the X-axis). By hinge-driving the mouthpiece 223, the suction port 225 of the mouthpiece 223 and the aerosol passage 224 can be selectively connected.

[0255] In one embodiment, one end of the air passage 270 (for example, the end in the -Z direction) communicates with the storage tank 230, and the other end of the air passage 270 (for example, the end in the +Z direction) is in contact with a part of the mouthpiece 223 (for example, the support portion 223b in Figure 4). The other end of the air passage 270 is opened and closed by the hinge drive of the mouthpiece 223.

[0256] In one embodiment, the mouthpiece 223 can be hinged between a first position in which the aerosol channel 224 and the inlet 225 are not in communication (for example, the position of the mouthpiece 223 in Figure 6a) and a second position in which the aerosol channel 224 and the inlet 225 are in communication (for example, the position of the mouthpiece 223 in Figure 6b).

[0257] In one embodiment, the mouthpiece 223 can move between a first position and a second position, closing the air passage 270 in the first position and opening the air passage 270 in the second position.

[0258] For example, as shown in Figure 6a, when the mouthpiece 223 is in the first position (or when the mouthpiece 223 is closed, or when the aerosol generator 200 is not in use), the other end of the air passage 270 may be in contact with the mouthpiece 223 and the air passage 270 may be closed.

[0259] For example, as shown in Figure 6b, when the mouthpiece 223 is in the second position (or when the mouthpiece 223 is open, or when the aerosol generator 200 is in use), the other end of the air passage 270 may be separated from the mouthpiece 223 and the air passage 270 may be open.

[0260] In one embodiment of this document, the air passage 270 can be opened and closed in conjunction with the mouthpiece 223, so that it can be selectively opened only when the aerosol generator 200 is in use. When the aerosol generator 200 is not in use, the air passage 270 is closed to prevent leakage of aerosol-generating material. When the aerosol generator 200 is in use, the air passage 270 is automatically opened in conjunction with the mouthpiece 223, which prevents a pressure drop inside the storage tank 230 and improves the liquid phase transfer force of the storage tank 230.

[0261] Figure 7 is an enlarged cross-sectional view of an aerosol generator 200 according to one embodiment.

[0262] Referring to Figure 7, the aerosol generator 200 according to one embodiment may further include a sealing member 275.

[0263] The following explanation will omit any content that overlaps with the above, and it goes without saying that in the aerosol generator 200, some configurations and structures may be replaced, added, or omitted to the extent that a person skilled in the art can easily understand them by referring to the following drawings and descriptions. Furthermore, the aerosol generator 200 may be combined with at least one configuration or feature of the above-described embodiment, unless it is technically clearly impossible.

[0264] In one embodiment, the sealing member 275 may be positioned in the mouthpiece 223 facing the air passage 270. The sealing member 275 can seal the air passage 270 and prevent liquid aerosol-generating material from leaking from the storage tank 230.

[0265] In one embodiment, the sealing member 275 can be inserted into the air passage 270 with the mouthpiece 223 in a first position (for example, the state of the mouthpiece 223 in Figure 7). However, Figure 7 is only one embodiment of the sealing member 275, and the structure and drive of the sealing member 275 in actual implementation are not limited thereto.

[0266] For example, the sealing member 275 may be a sealing pad attached to at least a portion of one surface of the mouthpiece 223 (e.g., the surface in the -Z direction). Alternatively, the sealing member 275 may have a cover or cap structure surrounding the other end of the air passage 270 (e.g., the end in the +Z direction).

[0267] In one embodiment, the sealing member 275 is made of an elastic material such as rubber, silicone, or TPU (thermoplastic polyurethane). Alternatively, the sealing member 275 may be made of a water-repellent material.

[0268] In one embodiment of this document, the mouthpiece 223 or sealing member 275 corresponds to an exemplary valve for controlling the opening and closing of the air passage 270. However, the structure and drive of the valve are not limited thereto, and the aerosol generator 200 may include valves of various structures and drive mechanisms.

[0269] For example, although not shown in the drawings, the aerosol generator 200 according to one embodiment may further include a valve that is driven in a fully automatic manner. The valve may be driven by a processor (for example, the control unit 110 in Figure 1).

[0270] In one embodiment, the processor can control the drive of the vibrator 241 and the valve. The processor can open the valve once the drive of the vibrator 241 is started.

[0271] For example, when the vibrator 241 is driven, the aerosol-generating material in the storage tank 230 moves, and the pressure inside the storage tank 230 decreases. In conjunction with this, the valve opens the air passage 270, supplying air to the inside of the storage tank 230.

[0272] In one embodiment, the aerosol generator 200 may further include a sensor (e.g., the detection unit 120 in Figure 1) for detecting hinge drive. The sensor can provide the detection result to a processor, which can open the valve if it detects that the mouthpiece 223 has been driven.

[0273] In one embodiment, the processor receives detection results from a puff sensor (for example, the puff sensor 126 in Figure 1), and if the user's puff action is detected, the processor can open the valve.

[0274] In one embodiment of this document, the processor can accurately and precisely control the pressure in the storage tank 230 by controlling the valve in a fully automatic manner to open and close the air passage 270.

[0275] The above description is an exemplary explanation of the drive mechanism for opening and closing the air passage 270 of the aerosol generator 200, and is not limited to this in actual implementation of the aerosol generator 200, which can be implemented with various structures and drive mechanisms.

[0276] Figure 8a is an enlarged cross-sectional view of an aerosol generator 200 according to one embodiment, and Figure 8b is an enlarged cross-sectional view of an aerosol generator 200 according to one embodiment.

[0277] Referring to Figures 8a and 8b, the aerosol generator 200 according to one embodiment may further include an auxiliary channel 280 and an elastic member 285.

[0278] The following explanation will omit any content that overlaps with the above, and it goes without saying that in the aerosol generator 200, some configurations and structures may be replaced, added, or omitted to the extent that a person skilled in the art can easily understand them by referring to the following drawings and descriptions. Furthermore, the aerosol generator 200 may be combined with at least one configuration or feature of the above-described embodiment, unless it is technically clearly impossible.

[0279] In one embodiment, one side of the auxiliary channel 280 (for example, the -Y direction in Figures 8a and 8b) may be open toward the air channel 270. The other side of the auxiliary channel 280 opposite to the one side (for example, the +Y direction in Figures 8a and 8b) is in communication with the aerosol channel 224.

[0280] In one embodiment, the elastic member 285 can be positioned inside the air passage 270 so as to surround one side of the auxiliary passage 280. The elastic member 285 may also seal one end of the auxiliary passage 280.

[0281] In one embodiment, the elastic member 285 may prevent the auxiliary channel 280 and the air channel 270 from communicating with each other. The elastic member 285 can prevent aerosols passing through the aerosol channel 224 from being transmitted to the air channel 270 via the auxiliary channel 280.

[0282] In one embodiment, the elastic member 285 can be deformed based on changes in the air pressure of the auxiliary channel 280. For example, the shape of the elastic member 285 may change due to changes in the air pressure of the auxiliary channel 280. Alternatively, for example, the elastic member 285 may expand or contract due to changes in the air pressure of the auxiliary channel 280. By deforming, the elastic member 285 can selectively open and close the air channel 270.

[0283] For example, as shown in FIG. 8a, in a state where the mouthpiece 223 is in the first position (or, in a state where the mouthpiece 223 is closed or the aerosol generator 200 is in an unused state), or when the user does not inhale air through the mouthpiece 223, the elastic member 285 may be in a state before deformation (or, in an expanded state). The elastic member 285 in the state before deformation is arranged to block the air flow path 270 and can block the fluid flow in the air flow path 270.

[0284] For example, as shown in FIG. 8b, in a state where the mouthpiece 223 is in the second position (or, in a state where the mouthpiece 223 is open or the aerosol generator 200 is in a used state), when the user inhales air through the mouthpiece 223, the suction port 225 and the aerosol flow path 224 relatively decrease in pressure and become a low-pressure state. When the aerosol flow path 224 becomes a low-pressure state, the pressure in the auxiliary flow path 280 communicating with the aerosol flow path 224 becomes low. When the air pressure in the auxiliary flow path 280 becomes low, the elastic member 285 is deformed (or, contracted). The deformed elastic member 285 opens the air flow path 270, and the air flow path 270 can temporarily supply external air to the storage tank 230.

[0285] In one embodiment, the elastic member 285 is made of an elastic body such as rubber, silicon, or TPU (thermoplastic polyurethane). Further, the elastic member 285 is made of a water-repellent substance.

[0286] In one embodiment of this document, the elastic member 285 is deformed in conjunction with the air pressure changes in the aerosol flow path 224 and the auxiliary flow path 280, and can selectively open and close the air flow path 270. The auxiliary flow path 280 and the elastic member 285 may selectively open the air flow path 270 only in the situation where the aerosol generating device 200 is used. The air flow path 270 is closed when the aerosol generating device 200 is not inhaled by the user, thereby preventing the leakage of the aerosol product substance inside the storage tank 230. The air flow path 270 is automatically opened when the aerosol generating device 200 is inhaled by the user, thereby supplying air into the storage tank 230 and preventing the pressure drop of the storage tank 230.

[0287] FIG. 9a is an enlarged cross-sectional view of an aerosol generating device 200 according to one embodiment, and FIG. 9b is an enlarged cross-sectional view of an aerosol generating device 200 according to one embodiment.

[0288] Referring to FIGS. 9a and 9b, the aerosol generating device 200 according to one embodiment may further include a leak prevention member 287.

[0289] The following will be described by omitting the content that overlaps with the above description. In the aerosol generating device 200, within the scope that can be easily understood by those skilled in the art with reference to the following drawings and descriptions, some components and structures may be alternated, added, or omitted, which is of course possible. Also, the aerosol generating device 200 can combine at least one configuration or feature of the above-described embodiments as long as it is not technically clearly impossible.

[0290] In one embodiment, the leak prevention member 287 can be disposed opposite to the elastic member 285 inside the air flow path 270. The leak prevention member 287 is disposed so as to contact the elastic member 285 in at least a partial region based on the state where the elastic member 285 is not deformed (for example, the state of the elastic member 285 in FIG. 9a), and can prevent the leakage of the liquid-phase aerosol product substance through the air flow path 270.

[0291] For example, as shown in Figure 9a, when the mouthpiece 223 is in the first position (or when the mouthpiece 223 is closed or the aerosol generator 200 is not in use), or when the user is not inhaling air through the mouthpiece 223, the leak-proof member 287 can seal the air passage 270 by contacting the elastic member 285 in its undeformed state (or in its expanded state). The undeformed elastic member 285 and the leak-proof member 287 can block the air passage 270 and interrupt the fluid flow in the air passage 270.

[0292] For example, as shown in Figure 9b, when the mouthpiece 223 is in the second position (or when the mouthpiece 223 is open or the aerosol generator 200 is in use), if the user inhales air through the mouthpiece 223, the air pressure in the auxiliary channel 280 decreases, and the elastic member 285 deforms (or contracts). When the elastic member 285 is deformed, the leak-proof member 287 and the elastic member 285 may be separated from each other in at least a portion of the area. In the deformed state, the elastic member 285 and the leak-proof member 287 are separated in at least a portion of the area, opening the air channel 270, which can supply outside air to the storage tank 230.

[0293] In one embodiment, the leak-preventing member 287 is made of an elastic material such as rubber, silicone, or TPU (thermoplastic polyurethane). Alternatively, the leak-preventing member 287 may be made of a water-repellent material.

[0294] In one embodiment, the leak-preventing member 287 has a shape that corresponds to the shape of the elastic member 285 before deformation. For example, if the elastic member 285 has a cap, hemisphere, polygon, or curved structure that protrudes inward into the air passage 270, the leak-preventing member 287 may have a shape that surrounds part or all of the elastic member 285 to seal the air passage 270.

[0295] In one embodiment of this document, the leak prevention member 287 can seal the elastic member 285, thereby sealing the air passage 270 when the user does not inhale the aerosol generator 200, and preventing the liquid phase aerosol-generating substance from leaking through the air passage 270.

[0296] Figure 10 is a cross-sectional view of an aerosol generator 300 according to one embodiment.

[0297] Referring to Figure 10, an aerosol generator 300 according to one embodiment (for example, aerosol generator 1 in Figure 1 or Figure 2, or any one of the aerosol generators 200 in Figures 3a to 9b) may include at least a portion of the housing 310 and the cartridge 320.

[0298] The following explanation will omit any content that overlaps with the above, and it goes without saying that in the aerosol generator 300, some configurations and structures may be replaced, added, or omitted to the extent that a person skilled in the art can easily understand them by referring to the following drawings and descriptions. Furthermore, at least one configuration or feature of the above-described embodiment can be combined with the aerosol generator 300, unless it is technically clearly impossible.

[0299] In one embodiment, the housing 310 may be the main housing of the aerosol generator 300, and may house the electrical components of the aerosol generator 300. The housing 310 includes an inlet 332. The user can inhale aerosols through the inlet 332.

[0300] In one embodiment, the housing 310 may further include at least a portion of the cartridge channel 314 and the aerosol channel 316. The cartridge channel 314 may communicate with the cartridge 320. The cartridge channel 314 may also be an opening through which aerosols are transmitted from the cartridge 320.

[0301] In one embodiment, the aerosol channel 316 may be connected to the cartridge channel 314 and the suction port 332. The aerosol channel 316 receives aerosol from the cartridge 320 via the cartridge channel 314.

[0302] In one embodiment, the cartridge 320 can be combined with the housing 310. The cartridge 320 can contain an aerosol-generating substance having at least some of the states of liquid, solid, gaseous, and gel. The cartridge 320 can be operated by an electrical signal or wireless signal transmitted from the housing 310, and can generate an aerosol by converting the phase of the contained aerosol-generating substance to a gaseous phase.

[0303] In one embodiment, the aerosol generated from the aerosol-generating substance in the cartridge 320 can pass through the cartridge channel 314 and move along the aerosol channel 316. The aerosol channel 316 transmits the aerosol to the intake port 332, and the aerosol is then transmitted to the user.

[0304] In one embodiment, the atomizing unit 311 can generate aerosols from an aerosol-generating substance. The atomizing unit 311 includes a heater 318 and an atomizing space 319. The atomizing unit 311 also includes a core 317 to which the aerosol-generating substance is transmitted and heated by the heater 318.

[0305] In one embodiment, the atomizing space 319 can communicate with the suction port 332. For example, the atomizing space 319 may communicate with the cartridge flow path 314, or it may communicate with the suction port 332 via the aerosol flow path 316.

[0306] In one embodiment, the storage tank 322 can be provided inside the cartridge 320. The storage tank 322 can store and hold an aerosol product substance inside. The aerosol product substance may include a liquid phase composition. The liquid phase composition may be a liquid containing a tobacco-containing substance including a volatile tobacco fragrance component, or may be a liquid containing a non-tobacco substance.

[0307] In one embodiment, when the aerosol product substance is transmitted to the wick 317, the liquid phase composition can be heated by the heater 318 to generate an aerosol. The generated aerosol is transmitted to the user.

[0308] In one embodiment, the cartridge flow path 314 can communicate with the atomization space 319. The cartridge flow path 314 communicates with the aerosol flow path 316 and can transmit the aerosol generated in the atomization space 319 to the aerosol flow path for transmission.

[0309] In one embodiment, the aerosol flow path 316 can communicate with the suction port 332 of the housing 310. The aerosol flow path 316 can transmit the aerosol from the atomization space 319 to the suction port 332. The aerosol generated by the atomization unit 311 passes through the cartridge flow path 314 and the aerosol flow path 316 and moves to the suction port 332.

[0310] In one embodiment, the aerosol generating device 300 may further include at least a part of a processor 340 (for example, the control unit 110 in FIG. 1) and a battery 347 (for example, the battery 140 in FIG. 1).

[0311] In one embodiment, the processor 340 can control the driving of the aerosol generating device 300. The battery 347 can store electric power for driving the aerosol generating device 300 and provide it to the components of the aerosol generating device 300.

[0312] In one embodiment, the aerosol generator 300 may further include at least a portion of the air passage 370 (for example, at least one air passage 270 from Figures 4 to 9b), the auxiliary passage 380 (for example, at least one auxiliary passage 280 from Figures 8a to 9b), and the elastic member 385 (for example, at least one elastic member 285 from Figures 8a to 9b).

[0313] In one embodiment, the air passage 370 can be opened in a direction toward the intake port 332 (or mouthpiece) from the inside of the storage tank 322. The air passage 370 can supply air to the inside of the storage tank 322 and control the pressure inside the storage tank 322.

[0314] In one embodiment of this document, the air passage 370 selectively connects the inside of the storage tank 322 to the outside of the storage tank 322 and can supply air to the inside of the storage tank 322. The air passage 370 can prevent a pressure drop inside the storage tank 322 caused by the operation of the aerosol generator 300 and improve the efficiency of liquid phase transfer in the storage tank 322.

[0315] In one embodiment, one side of the auxiliary channel 380 (for example, the +Y direction in Figure 10) can be open toward the air channel 370. The other side of the auxiliary channel 380 opposite to that side (for example, the -Y direction in Figure 10) is in communication with the aerosol channel 324.

[0316] In one embodiment, the elastic member 385 may be positioned inside the air channel 370 so as to surround one side of the auxiliary channel 380. The elastic member 385 may seal one end of the auxiliary channel 380. The elastic member 385 prevents the auxiliary channel 380 and the air channel 370 from communicating with each other. The elastic member 385 can prevent aerosols passing through the aerosol channel 324 from being transmitted to the air channel 370 via the auxiliary channel 380.

[0317] In one embodiment, the elastic member 385 can be deformed based on changes in the air pressure of the auxiliary channel 380. For example, the shape of the elastic member 385 may change due to changes in the air pressure of the auxiliary channel 380. Alternatively, the elastic member 385 may expand or contract due to changes in the air pressure of the auxiliary channel 380. Therefore, the elastic member 385 can selectively open and close the air channel 370.

[0318] For example, when the aerosol generator 300 is not in use or when the user is not inhaling air through the intake port 332, the elastic member 385 is in its pre-deformed state (or expanded state). In its pre-deformed state, the elastic member 385 is positioned to obstruct the air passage 370, thereby blocking the fluid flow in the air passage 370.

[0319] For example, when a user inhales air from the aerosol generator, the pressure in the intake port 325 and the aerosol channel 324 decreases relatively, resulting in a low-pressure state. When the aerosol channel 324 is in a low-pressure state, the pressure in the auxiliary channel 380, which is connected to the aerosol channel 324, also decreases. The elastic member 385 deforms (or contracts) when the air pressure in the auxiliary channel 380 decreases. In its deformed state, the elastic member 385 opens the air channel 370, which can temporarily supply outside air to the storage tank 322.

[0320] In one embodiment, the elastic member 385 is made of an elastic material such as rubber, silicone, or TPU (thermoplastic polyurethane). Alternatively, the elastic member 385 may be made of a water-repellent material.

[0321] In one embodiment of this document, the elastic member 385 deforms in conjunction with changes in air pressure in the aerosol channel 324 and the auxiliary channel 380, allowing for selective opening and closing of the air channel 370. The auxiliary channel 380 and the elastic member 385 can selectively open the air channel 370 only when the aerosol generator 300 is in use. The air channel 370 is closed when the aerosol generator 300 is not being drawn in by the user, thereby preventing leakage of aerosol-generating material from inside the storage tank 322. The air channel 370 is automatically opened when the aerosol generator 300 is being drawn in by the user, supplying air to the inside of the storage tank 322 and preventing a pressure drop in the storage tank 322.
