At least a part of the storage unit 1100 of the cartridge 1000 may include a transparent material so that the aerosol generating material 10 stored inside the cartridge 1000 can be visually confirmed from the outside. The entire storage unit 1100 may be made of a material such as transparent plastic or glass, and only a portion of the storage unit 1100 may be made of a transparent material.

The opening 1111 may refer to a hole through which the aerosol generating material 10 stored in the storage unit 1100 is discharged to the outside of the storage unit 1100 . For example, the opening 1111 may be formed through at least a portion of the storage unit 1100, and when the opening 1111 is opened, the aerosol generating material 10 may flow out of the storage unit 1100.

The cartridge 1000 closes the opening 1111 to limit the aerosol generating material 10 from coming out of the storage unit 1100, but when an external force is applied, the aerosol generating material 10 moves out of the storage unit 1100. It may include a stopper 1200 that moves to open the opening 1111 so that it can come out.

Here, the meaning of 'the stopper moving' may mean anything that moves the stopper 1200 from its original position to another position when an external force is applied to the stopper 1200 . For example, failure of the stopper 1200 made of a brittle material by receiving an external force may be included therein.

The stopper 1200 is fixed in a closed position capable of closing the opening 1111 of the reservoir 1100 when the cartridge 1000 is not in use, for example, when the cartridge 1000 is not coupled to the main body of the aerosol generating device. may have been

Here, the 'closed position' may refer to a position where the stopper 1200 closes the opening 1111 so that the aerosol generating material 10 cannot flow out of the storage unit 1100 . The expression may be used in the same meaning below unless otherwise noted.

However, when the stopper 1200 moves from the closed position to another position due to an external force or a user's manipulation, the opening 1111 is opened and the stopper 1200 may move to the open position.

Here, the 'open position' is a concept opposite to the closed position, and may mean a position in which the stopper 1200 opens the opening 1111 so that the aerosol generating material 10 can flow out of the storage unit 1100. there is. The expression may be used in the same meaning below unless otherwise noted.

As the stopper 1200 moves from the closed position to the open position, the aerosol generating material 10 may flow out of the storage unit 1100 through the opening 1111 . Accordingly, the aerosol generating material 10 may be ejected from the cartridge 1000 .

According to one embodiment, the cartridge 1000 may further include an elastic element 1300 fixing the stopper 1200 in a closed position to close the opening 1111 . For example, the elastic element 1300 may be a spring that elastically presses the stopper 1200 in a direction to close the opening 1111 .

However, when an external force stronger than the elastic force of the elastic element 1300 is applied to the stopper 1200, the stopper 1200 resists the elastic element and can move from the closed position to the open position, thereby opening the opening 1111. It can be.

The elastic element 1300 may be a coil spring, but is not limited thereto, and may be a plate spring or a polymer spring. In addition, the intensity of external force required to move the stopper 1200 may vary according to characteristics such as material properties, dimensions, and number of turns of the elastic element 1300 .

In the present disclosure, 'external force' may mean a force applied to the stopper 1200 . For example, a force applied directly to the stopper 1200 by being inserted into the cartridge 1000 through the discharge passage 1500 of the cartridge 1000 by an object applying an external force, as well as sudden acceleration It may also mean an inertia force acting on the cartridge 1000 by. The expression may be used in the same meaning below unless otherwise noted.

More detailed information about the opening and closing of the opening 1111 according to the external force applied to the stopper 1200 will be described later using FIGS. 2A and 2B.

According to one embodiment, the storage unit 1100 may include a guide unit 1110 for guiding the movement of the stopper 1200 . Specifically, the storage unit 1100 has a cylindrical shape, and a cylindrical guide unit 1110 having a smaller size than the storage unit 1100, which guides the movement of the stopper 1200, may be included in the storage unit 1100. there is. Accordingly, the storage unit 1100 may have a hollow tube shape having a hollow by the cylindrical guide unit 1110.

At this time, the opening 1111 may be formed in the guide part 1110 . For example, the opening 1111 may be a hole penetrating at least a portion of the guide part 1110 .

According to one embodiment, the cartridge 1000 may further include a hooking portion 1400 . The hooking portion 1400 may protrude from the outer circumferential surface of the storage portion 1100 to restrict movement of the stopper 1200 protruding out of the cartridge 1000 .

As the cartridge 1000 includes the locking portion 1400, a configuration for limiting the position of the stopper 1200 to a predetermined range so that the stopper 1200 is located inside the cartridge 1000, for example, elastic. Even if the element 1300 is not present or the elastic element 1300 and the stopper 1200 are not coupled, the stopper 1200 may prevent the cartridge 1000 from protruding outwardly.

According to one embodiment, the cartridge 1000 may include an outlet passage 1500 of the aerosol generating material 10 . The discharge passage 1500 may mean a passage through which the aerosol generating material 10 moves out of the cartridge 1000 .

Specifically, the discharge passage 1500 may extend in the same direction as a portion coupled to the body to be described later. When the opening 1111 is open, the discharge passage 1500 is in fluid communication with the opening 1111, and the aerosol generating material 10 coming out of the reservoir 1100 flows through the discharge passage 1500, and the cartridge ( 1000) can be discharged to the outside. That is, when the stopper 1200 moves to the open position, the aerosol generating material 10 contained in the storage unit 1100 passes through the opening 1111 and moves to the discharge passage 1500, and moves outside the cartridge 1000. can be emitted as

According to one embodiment, the cartridge 1000 is also connected to the passage 1600 and the passage 1600 through which the aerosol generated by the atomization of the aerosol generating material 10 moves, and the mouthpiece 1700 discharging the aerosol to the outside. ) may further include.

Specifically, the flow path 1600 is formed inside the cartridge 1000 and may be in fluid communication with the mouthpiece 1700 connected to the outside of the cartridge 1000 . The aerosol generated by atomizing the aerosol generating material 10 moves to the mouthpiece along the flow path 1600 and may be discharged to the outside of the cartridge 1000 .

The mouthpiece 1700 may be formed in the opposite direction to a portion coupled to the body to be described later, and may be a portion inserted into the user's oral cavity. The mouthpiece 1700 may include a discharge hole through which aerosol moving inside the cartridge 1000 is discharged to the outside.

According to one embodiment, the flow passage 1600 may be formed through the inside of the cartridge 1000 and connected to the mouthpiece 1700 . Also, the cartridge 1000 may include at least one storage unit 1100, and each of the at least one storage unit 1100 may be disposed outside the flow path 1600 in a circumferential direction.

For example, the passage 1600 may be formed through a substantially central portion of the cartridge 1000 . In addition, two storage units 1100 are disposed outside the flow path 1600 at 180 degree intervals and on both sides of the flow path 1600, or four storage units 1100 are disposed outside the flow path 1600 at intervals of 90 degrees. , may be disposed on all sides of the flow path 1600. However, the arrangement of the flow path 1600 and the at least one storage unit 1100 is not limited thereto, and varies depending on the size of the cartridge 1000, the number of storage units 1100, and/or the size of the storage unit 1100. can be placed appropriately.

The plurality of reservoirs 1100 may include aerosol generating materials 10 having different types and/or ratios of ingredients, respectively. Depending on the needs of the user, an aerosol generating material 10 comprising different components may be selectively used. For example, one of the storage units 1100 may store the aerosol generating material 10 containing a nicotine salt, and the other storage unit 1100 may store the aerosol generating material 10 containing a flavoring agent. ) can be stored.

According to one embodiment, the cartridge 1000 further comprises a barrier structure 1720 that blocks un-atomized aerosol generating material 10 and/or aerosol from traveling along the flow path 1600 to the mouthpiece 1700. can do. For example, the blocking structure 1720 may protrude from at least a portion of an inner wall of the cartridge 1000 .

Here, the 'non-atomized aerosol and/or aerosol generating material' may refer to an aerosol generating material 10 and/or an aerosol having a size that may reduce smoking satisfaction and cause discomfort when a user inhales.

The aerosol-generating material 10 and/or the aerosol may move along the flow path 1600 without being atomized by vibration of the vibrator. The non-atomized aerosol-generating material 10 and/or the aerosol lose at least some of their kinetic energy by collision with the blocking structure 1720, so that flow to the mouthpiece 1700 is blocked, or the blocking structure 1720 and It may be atomized to a smaller size by the collision of.

The cartridge 1000 may also include a sorption structure 1730 to prevent accumulation of un-atomized aerosol generating material 10 and/or aerosol in the flow path 1600 . The absorption structure 1730 may include cotton or cloth that absorbs liquid or aerosol, or may include activated carbon that absorbs liquid or aerosol.

The sorption structure 1730 may be positioned adjacent to the blocking structure 1720 . For example, the sorption structure 1730 may be located around the blocking structure 1720 and disposed outside the flow path 1600 in a circumferential direction similarly to the arrangement of the storage unit 1100 .

The cartridge 1000 includes the blocking structure 1720 and the sorption structure 1730, and the non-atomized aerosol-generating material 10 and/or aerosol that has lost at least a part of its kinetic energy by collision with the blocking structure 1720 It can be absorbed by the absorbent structure. Accordingly, accumulation of the non-atomized aerosol generating material 10 and/or aerosol in the flow path 1600 and/or the mouthpiece 1700 can be prevented, and the user's smoking satisfaction can be improved.

The cartridge 1000 may include a cartridge casing 1800, and the cartridge casing 1800 may protect the above-described components included in the cartridge 1000 from impact and/or contamination.

The cartridge 1000 according to the present disclosure may be used after being filled with the aerosol generating material 10, but may also be replaced with a disposable one. Further, the cartridge 1000 can be assembled with simple configurations as described above, so that it can be produced at a low cost suitable for single use.

In addition, since the cartridge 1000 can be replaced whenever the aerosol generating material 10 is exhausted, in the case of including the mouthpiece 1700, the mouthpiece 1700 can be replaced regularly. Accordingly, user convenience and hygiene may be improved.

2A is an enlarged view of portion A of FIG. 1A, and FIG. 2B is an enlarged view of portion B of FIG. 1B.

FIG. 2A shows an aspect in which the stopper 1200 closes the opening 1111 in a closed position, and FIG. 2B shows an aspect in which the stopper 1200 opens the opening 1111 in an open position.

Referring to FIGS. 2A and 2B , the storage unit 1100 may include a guide unit 1110 , and the guide unit 1110 may include an opening 1111 . Also, the discharge passage 1500 may include the protrusion 1510, and as described above, the stopper 1200 and the elastic element 1300 may be included.

As described in FIGS. 1A and 1B , the storage unit 1100 may include a guide unit 1110 . As the storage unit 1100 includes the guide unit 1110, the storage unit 1100 may have a hollow shape, and the stopper 1200 and the elastic element 1300 are included inside the hollow, but the aerosol Product material 10 may be excluded. For example, the stopper 1200 can move inside the hollow, and the elastic element 1300 can be compressed or stretched inside the hollow. However, the aerosol generating material 10 may exist in a space between the inside of the storage unit 1100 and the outside of the guide unit 1110 .

Referring to FIG. 2A , when no external force is applied to the stopper 1200, the stopper 1200 may be fixed in the closed position by the elastic force of the elastic element 1300 and the reaction force of the hooking portion 1400. Specifically, when the stopper 1200 is fixed in the closed position, such as when the cartridge is stored unused, it is difficult for the aerosol generating material 10 stored in the storage unit 1100 to escape to the outside of the cartridge. Therefore, leakage of the cartridge can be prevented.

Referring to FIG. 2B , an external force F may be applied to the stopper 1200 by an object 2200 applying an external force, for example, a pressurizing portion described later. When an external force F is applied to the stopper 1200, the stopper 1200 resists the elastic force of the elastic element 1300 to compress the elastic element 1300 along the direction in which the external force F is applied, It can be moved to an open position. Here, an arrow indicating the external force F may indicate an action direction of the external force applied to the stopper 1200 . However, the direction of application of the external force is not limited to the illustrated direction, and may be any one of a direction opposite to that illustrated, a direction crossing the illustrated direction, and a rotating direction according to various embodiments.

As the stopper 1200 moves to the open position, the opening 1111 of the storage unit 1100 formed in the guide unit 1110 may be opened. The aerosol generating material 10 stored in the storage unit 1100 passes through the opening 1111 and moves to the discharge passage 1500, whereby the aerosol generating material 10 can be discharged to the outside of the cartridge.

As such, the stopper 1200 may open the opening 1111 of the storage portion 1100 only when an external force sufficient to overcome the elastic force of the elastic element 1300 is applied to the stopper 1200 . That is, the aerosol generating material 10 is discharged from the cartridge only when the use of the cartridge is intended, and leakage of the cartridge can be prevented semi-permanently or permanently when the use of the cartridge is not intended, so that the convenience of use can be increased. there is.

On the other hand, in the cartridge according to the present disclosure, the configuration for restraining the movement of the stopper 1200 when no external force is applied to the stopper 1200 is the elastic element 1300 that presses the stopper 1200 to a closed position. It is not limited to, and those skilled in the art can understand without difficulty that various components capable of controlling the position of the stopper 1200 may be included.

For example, a cartridge according to another embodiment may include, in addition to the elastic element 1300 , a membrane that is broken when a predetermined pressure or more is applied to remove restraint of the stopper 1200 . A cartridge according to another embodiment may include a key groove formed in each of the stopper 1200 and the storage unit 1100, and a key inserted into the key groove. The key couples the stopper 1200 and the storage portion 1100, but when a pressure equal to or greater than a predetermined value is applied, the key is destroyed so that the stopper 1200 can move and thus the opening 1111 can be opened.

The discharge passage 1500 may include a protruding portion 1510 protruding in a direction in which the cartridge is coupled to a body to be described later. The protruding portion 1510 may prevent the discharge passage 1500 from being unintentionally applied to the stopper 1200 by an object outside the cartridge by protruding toward the outside of the cartridge.

Specifically, the stopper 1200 may be located relatively deep from the outside of the cartridge based on the extreme end of the protrusion 1510 compared to the case where the protrusion 1510 does not exist in the discharge passage 1500. . Accordingly, the possibility of unintentional contact of the stopper 1200 with an external object is reduced, and the stopper 1200 may be prevented from moving to an open position.

Here, 'the most end of the protrusion' may refer to a part of the protrusion 1510 spaced farthest from the stopper 1200 . In addition, the protrusion 1510 may facilitate a user's coupling operation with the main body of the aerosol generating device, which will be described later. Specifically, since the part where the pressing part included in the main body is inserted into the cartridge is indicated by the protruding part 1510, the protruding part 1510 may guide the insertion position or insertion direction of the pressing part.

The cartridge 1000 may be combined with the main body 2000 while storing the aerosol generating material 10 therein. For example, a part of the cartridge 1000 may be inserted into the main body 2000 or a part of the main body 2000 may be inserted into the cartridge 1000 so that the cartridge 1000 may be mounted on the main body 2000 .

For example, the main body 2000 and the cartridge 1000 may maintain a coupled state by a snap-fit method, a screw coupling method, a magnetic coupling method, an interference fit method, or the like, but the main body 2000 And the coupling method of the cartridge 1000 is not limited by the bar described above.

According to one embodiment, the cartridge 1000 includes a first engagement holding element, and the main body 2000 maintains a coupled state between the cartridge 1000 and the main body 2000 by interacting with the first engagement holding element. A second engagement holding element may be included. For example, each of the first engagement holding element and the second engagement holding element may be any one of a hook and a groove, a screw and a screw groove, and a magnet.

The accommodating portion 2100 may accommodate the aerosol generating material 10 discharged from the storage portion of the cartridge 1000 when combined with the cartridge 1000 . The received aerosol-generating material 10 may be delivered to an atomizer that atomizes the aerosol-generating material 10 .

In the present disclosure, 'the aerosol generating material is discharged' may mean that the aerosol generating material 10 stored in the storage unit of the cartridge 1000 comes out of the storage unit and eventually comes out of the cartridge 1000. .

'Accommodating the aerosol-generating substance' inside the accommodating part 2100 means that the accommodating part 2100 simply performs a function of containing the aerosol-generating material 10, such as the use of a bowl, and the It may also mean including an element impregnating (containing) an absorber 2110 such as sponge, cotton, or cloth, or an aerosol generating material 10 such as a porous ceramic structure.

The accommodating part 2100 may include an absorber 2110 that absorbs the aerosol generating material 10 .

In addition, the absorber 2110 may be disposed adjacent to an atomizer to be described later to deliver the aerosol generating material 10 accommodated in the accommodating portion 2100 to the atomizer. For example, the absorber 2110 may be a wick including at least one of cotton fiber, ceramic fiber, glass fiber, and porous ceramic, but is not limited thereto.

The pressure unit 2200 may apply an external force to the stopper 1200 to move the stopper 1200 as the main body 2000 of the aerosol generating device 100 and the cartridge 1000 are coupled. The pressing part 2200 may contact the stopper 1200 to apply an external force to the pressing part 2200 .

Specifically, when the cartridge 1000 and the main body 2000 are coupled, the pressing part 2200 applies an external force to the stopper 1200 so that the stopper 1200 is in the closed position of the opening 1111 (see FIG. 3A). It can be moved to the open position of the opening 1111 (see FIG. 3B). Accordingly, the main body 2000 and the cartridge 1000 are coupled, and at the same time, the aerosol generating material 10 can move along the discharge passage 1500 from the cartridge 1000 to the accommodating portion 2100 of the main body 2000. .

The atomizer may include a vibrator 2300 generating ultrasonic vibrations and a vibration transmitting unit (not shown) generating aerosol by transmitting ultrasonic vibrations to the aerosol generating material 10 absorbed by the absorber 2110. The vibration transmitting unit may perform a function of receiving vibration generated from the vibrator 2300 and converting the aerosol generating material 10 transmitted from the receiving unit 2100 into an aerosol.

The vibrator 2300 may generate vibration of a short period. The vibration generated from the vibrator 2300 may be ultrasonic vibration, and the frequency of the ultrasonic vibration may be, for example, 100 kHz to 3.5 MHz. The aerosol-generating material 10 may be vaporized and/or made into particles by the short-cycle vibration generated from the vibrator 2300 to be atomized into an aerosol.

The vibrator 2300 may include, for example, piezoelectric ceramic, which generates electricity (voltage) by physical force (pressure) and conversely generates vibration (mechanical force) when electricity is applied. It is a functional material that can convert between electricity and mechanical power. Therefore, vibration (physical force) is generated by electricity applied to the vibrator 2300, and such small physical vibration can break the aerosol generating material 10 into small particles and atomize it into an aerosol.

According to one embodiment, the main body 2000 may further include a processor 2400 that controls operation by receiving or transmitting an electrical signal from an electrical component included in the aerosol generating device 100 .

Also, the vibrator 2300 may be electrically connected to the processor 2400 and the battery 2500 through the connector 2700 . For example, the processor 2400 and the battery 2500 may be electrically connected to the vibrator 2300 through a connector 2700 such as a pogo pin or a C-clip. The vibrator 2300 may generate vibration by receiving current or voltage from a pogo pin or a C-clip. However, the type of connector 2700 used to supply current or voltage to the vibrator 2300 is not limited as described above.

The atomizer also absorbs the aerosol generating material 10 without using a separate absorber 2110 and maintains it in an optimal state for converting it into an aerosol, and transmits vibration to the aerosol generating material 10 to generate an aerosol. It may be implemented as a mesh shape or plate shape vibration transfer unit that performs all functions.

Meanwhile, in the embodiment shown in FIGS. 3A and 3B, both the vibrator 2300 and the absorber 2110 of the atomizer are disposed on the main body 2000, but are not limited thereto.

As shown, the atomizing space 2600 may be a space in fluid communication with the vibrator 2300 and/or the absorber 2110. When the phase of the aerosol generating material 10 absorbed by the absorber 2110 is changed by the vibrator 2300, aerosol may be generated in the atomizing space 2600.

The aerosol generated in the atomizing space 2600 moves in the direction toward the cartridge 1000, moves in the direction toward the mouthpiece 1700 through the passage 1600 connected to the atomizing space 2600, and the aerosol generating device ( 100) can be discharged to the outside. Here, 'the aerosol is discharged' may mean that the aerosol moves from the inside of the aerosol generating device 100 to the outside of the aerosol generating device 100 .

The body 2000 may include a body casing 2800, and the body casing 2800 may protect the aforementioned components included in the body 2000 from impact and/or contamination. For example, the body casing 2800 can protect the pressurizing part 2200 and the vibrator 2300 from external impact, and can prevent foreign substances from entering the accommodating part 2100 .

According to one embodiment, a hook (not shown) is formed in the body casing 2800, and a hook groove (not shown) capable of engaging with the hook is formed in the cartridge casing 1800, and the hook is coupled to the hook groove. A state in which the body 2000 and the cartridge 1000 are coupled may be maintained.

The aerosol generating device 100 may further include an air flow path (not shown). The air flow path is a passage through which external air can be introduced into the aerosol generating device 100 . External air introduced through the air flow path may be introduced into the passage 1600 of the cartridge 1000 or may be introduced into the atomization space 2600 where aerosol is generated. Accordingly, an aerosol may be generated by mixing with the vaporized particles generated from the aerosol-generating material 10 .

For example, the air flow path may be formed to surround the outside of the flow path 1600 . Specifically, the shape of the flow path 1600 and the air flow path may be a double pipe shape in which the flow path 1600 is disposed inside and the air flow path is disposed outside the flow path 1600 . Through this, external air may flow in the direction opposite to the direction in which the aerosol moves in the flow path 1600 .

On the other hand, the structure of the air flow path is not limited by the above. For example, the air flow path may be a space formed between the main body 2000 and the cartridge 1000 when the main body 2000 and the cartridge 1000 are coupled and in fluid communication with the atomizing space 2600.

In the aerosol generating device 100 according to the above-described embodiment, the cross-sectional shape in the direction transverse to the longitudinal direction of the main body 2000 and the cartridge 1000 is approximately circular, elliptical, square, rectangular, or various polygonal cross-sections. can be a shape.

However, the cross-sectional shape of the aerosol generating device 100 is not limited by the above, and the aerosol generating device 100 is not necessarily limited to a structure extending in a straight line when extending in the longitudinal direction. For example, the cross-sectional shape of the aerosol generating device 100 may be curved in a streamlined shape to make it easier for a user to hold by hand, or may be bent at a predetermined angle in a specific area and extended long. It can change along direction.
