Description

Cartridge and aerosol generating device containing same

[0001] Various embodiments of the present disclosure relate to a cartridge and an aerosol generating device including the same, and more particularly, to a cartridge having an improved sealing structure and an aerosol generating device including the same.

[0002] Recently, there has been a growing demand for alternative methods that overcome the shortcomings of conventional cigarettes. For example, there is a growing demand for systems that generate aerosol by heating cigarettes or aerosol-generating materials using an aerosol generator, rather than by burning cigarettes to produce aerosol. Accordingly, research into heated aerosol generators is actively underway.

[0003] Meanwhile, in the field of aerosol generating devices that use liquid aerosol generating substances, research on preventing liquid leakage and sealing is actively being conducted.

[0004] The cartridge of the aerosol generating device generally includes a storage unit for storing a liquid substance (hereinafter, the liquid substance may be used interchangeably with the term "aerosol generating substance" and is abbreviated as "liquid"), and a generation unit for generating an aerosol from the liquid. The liquid stored in the storage unit is transferred to the generation unit, and the liquid can be atomized into an aerosol by the generation unit.

[0005] In a structure where liquid is transferred from a storage unit to a production unit, the storage unit and the production unit may be surrounded by surrounding components and separated from each other. The internal components contained within the cartridge are tightly coupled to each other, but due to the nature of the liquid, the liquid may leak through gaps between the components.

[0006] Therefore, there is a need to prevent liquid from flowing along paths other than the intended path, into other configurations, and even out of the cartridge. Conventional cartridges feature sealing elements inside the cartridge to prevent this. However, to maximize the sealing effect, the entire cartridge requires structural improvement.

[0007] Embodiments provide a cartridge having components forcibly fitted into a housing of the cartridge and an aerosol generating device including the same.

[0008] Embodiments provide a cartridge having a sealing element integrated into a component forcibly fitted into a housing and an aerosol generating device including the same.

[0009] The problems to be solved through the embodiments are not limited to the problems described above, and problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the embodiments belong from this specification and the attached drawings.

[0010] A cartridge according to one embodiment may include a housing including a storage space for storing an aerosol-generating substance, a sealing portion including one or more discharge ports for passing the aerosol-generating substance and sealing a portion of the storage space, a generating portion for generating an aerosol from the aerosol-generating substance, a receiving portion for receiving the generating portion and contacting the sealing portion within the housing to form a generating space in which an aerosol is generated together with the sealing portion, and a cover for supporting the receiving portion so as to pressurize the receiving portion and the sealing portion toward the storage space and for closing one end of the housing.

[0011] According to the cartridge and the aerosol generating device including the same according to the embodiments, since a separate material with strong adhesiveness does not need to be used, the manufacturing of the cartridge can be simplified and the manufacturing cost can be reduced.

[0012] In addition, according to the cartridge and the aerosol generating device including the same according to the embodiments, the sealing effect inside the cartridge is improved, so that leakage of the aerosol generating material can be prevented.

[0041] Figures 1 and 2 illustrate an aerosol generating device (1) according to embodiments of the present disclosure.

[0042] Referring to FIG. 1, an aerosol generating device (1) may include at least one of a power source (11), a control unit (12), a sensor (13), a heater (18), and a cartridge (19). At least one of the power source (11), the control unit (12), the sensor (13), and the heater (18) may be disposed inside a body (10) of the aerosol generating device. The body (10) may provide a space opened upwardly so that a stick (S), which is an aerosol generating article (hereinafter, may be used with the same meaning as “aerosol generating article”), may be inserted. The space opened upwardly may be referred to as an insertion space. The insertion space may be formed by being recessed toward the inside of the body (10) by a predetermined depth so that at least a portion of the stick (S) can be inserted. The depth of the insertion space may correspond to the length of a region of the stick (S) containing an aerosol generating material and / or medium. The lower end of the stick (S) is inserted into the inside of the body (10), and the upper end of the stick (S) can protrude outside the body (10). The user can inhale air by putting the upper end of the stick (S) exposed to the outside in his / her mouth.

[0043] The heater (18) can heat the stick (S). The heater (18) can extend upwardly around the space where the stick (S) is inserted. For example, the heater (18) can be in the form of a tube having a hollow space therein. The heater (18) can be placed around the insertion space. The heater (18) can be placed to surround at least a portion of the insertion space. The heater (18) can heat the insertion space or the stick (S) inserted into the insertion space. The heater (18) can include an electrical resistance heater and / or an induction heater.

[0044] For example, the heater (18) may be a resistive heater. For example, the heater (18) may include an electrically conductive track, and the heater (18) may be heated as current flows through the electrically conductive track. The heater (18) may be electrically connected to a power source (11). The heater (18) may be directly heated by receiving current from the power source (11).

[0045] For example, the aerosol generating device (1) may include an induction coil surrounding a heater (18). The induction coil may heat the heater (18). The heater (18) may be a susceptor, and the heater (18) may be heated by a magnetic field generated by an AC current flowing through the induction coil. The magnetic field may penetrate the heater (18) and generate an eddy current within the heater (18). The current may generate heat in the heater (18).

[0046] Meanwhile, a susceptor may be included inside the stick (S), and the susceptor inside the stick (S) may be heated by a magnetic field generated by an AC current flowing through the induction coil.

[0047] The cartridge (19) may contain an aerosol-generating substance in any one of a liquid, solid, gaseous, or gel state. The aerosol-generating substance may comprise a liquid composition. For example, the liquid composition may be a liquid comprising a tobacco-containing substance including volatile tobacco flavoring components, or may be a liquid comprising a non-tobacco substance.

[0048] The cartridge (19) may be formed integrally with the body (10) or may be detachably coupled to the body (10).

[0049] For example, referring to FIG. 1, the cartridge (19) is formed integrally with the body (10) and can communicate with the insertion space through an airflow channel (CN).

[0050] For example, referring to FIG. 2, a space is formed on one side of the body (10), and at least a portion of the cartridge (19) is inserted into the space formed on one side of the body (10) so that the cartridge (19) can be mounted on the body (10). The airflow channel (CN) can be defined by a portion of the cartridge and / or a portion of the body (10), and the cartridge (19) can communicate with the insertion space through the airflow channel (CN).

[0051] The body (10) can be formed in a structure in which outside air can flow into the interior of the body (10) while the cartridge (19) is inserted. At this time, the outside air flowing into the body (10) can pass through the cartridge (19) and flow into the user's oral cavity.

[0052] The cartridge (19) may include a storage portion (C0) containing an aerosol generating material and / or a cartridge heater (24) for heating the aerosol generating material in the storage portion (C0). A liquid delivery means impregnating (containing) the aerosol generating material may be disposed inside the storage portion (C0). Here, the liquid delivery means may include a wick such as cotton fiber, ceramic fiber, glass fiber, porous ceramic, etc. The electrically conductive track of the cartridge heater (24) may be formed in a coil-shaped structure that winds the liquid delivery means or a structure that contacts one side of the liquid delivery means. The cartridge heater (24) may be referred to as a cartridge heater (24).

[0053] The cartridge (19) can generate an aerosol. The aerosol can be generated as the liquid delivery means is heated by the cartridge heater (24). The aerosol can be generated by heating the stick (S) by the heater (18). Tobacco material can be added to the aerosol while the aerosol generated by the cartridge heater (24) and the heater (18) passes through the stick (S), and the aerosol added with the tobacco material can be inhaled into the user's mouth through one end of the stick (S).

[0054] The aerosol generating device (1) may be equipped with only a cartridge heater (24) and the body (10) may not be equipped with a heater (18). In this case, the aerosol generated by the cartridge heater (24) may pass through the stick (S) and be mixed with tobacco material and inhaled into the user's mouth.

[0055] The aerosol generating device (1) may include a cap (not shown). The cap may be detachably coupled to the body (10) so as to cover at least a portion of a cartridge (19) coupled to the body (10). A stick (S) may be inserted into the body (10) through the cap.

[0056] The power source (11) can supply power to the components of the aerosol generating device to operate. The power source (11) can be referred to as a power source. The power source (11) can supply power to at least one of the control unit (12), the sensor (13), the cartridge heater (24), and the heater (18). When the aerosol generating device (1) includes an induction coil, the power source (11) can supply power to the induction coil.

[0057] The control unit (12) can control the overall operation of the aerosol generating device. The control unit can be mounted on a printed circuit board (PCB). The control unit (12) can control the operation of at least one of the power supply (11), the sensor (13), the heater (18), and the cartridge (19). The control unit (12) can control the operation of a display, a motor, etc. installed in the aerosol generating device. The control unit (12) can check the status of each component of the aerosol generating device to determine whether the aerosol generating device is in an operable state.

[0058] The control unit (12) can analyze the results detected by the sensor (13) and control the processes to be performed thereafter. For example, the control unit (12) can control the power supplied to the cartridge heater (24) and / or the heater (18) so that the operation of the cartridge heater (24) and / or the heater (18) is started or ended based on the results detected by the sensor (13). For example, the control unit (12) can control the amount of power supplied to the cartridge heater (24) and / or the heater (18) and the time for which the power is supplied so that the cartridge heater (24) and / or the heater (18) can be heated to a predetermined temperature or maintained at an appropriate temperature based on the results detected by the sensor (13).

[0059] The sensor (13) may include at least one of a temperature sensor, a puff sensor, an insertion detection sensor, a color sensor, a cartridge detection sensor, and a cap detection sensor. For example, the sensor (13) may sense at least one of the temperature of the heater (18), the temperature of the power source (11), and the temperature inside and outside the body (10). For example, the sensor (13) may sense the user's puff. For example, the sensor (13) may sense whether the stick (S) is inserted into the insertion space. For example, the sensor (13) may sense whether the cartridge is mounted. For example, the sensor (13) may sense whether the cap is mounted.

[0060] FIG. 3 is a front perspective view of an aerosol generating device according to one embodiment of the present disclosure.

[0061] Referring to FIG. 3, an aerosol generating device (100) according to one embodiment of the present disclosure may include a cap (1000) and a body (1100). In this case, the body (1100) may be identical to or similar to the body (10) of FIGS. 1 and 2.

[0062] The cap (1000) may be coupled to one end of the body (1100), so that the body (1100) and the cap (1000) together form the exterior of the aerosol generating device (100). The cap (1000) may include an opening (1000h) into which an aerosol generating article (S) may be inserted on the upper surface of the cap (1000).

[0063] The body (1100) forms a portion of the exterior of the aerosol generating device (100) and may perform a function of accommodating and protecting components of the aerosol generating device (100). For example, a power source, a control unit, and / or a heater may be accommodated within the body (1100), but embodiments are not limited thereto. In addition, the body (1100) may accommodate an aerosol generating article (S) inserted through an opening (1000h).

[0064] The body (1100) and cap (1000) may be manufactured from a plastic material that does not conduct heat well, or a metal material whose surface is coated with a heat-insulating material. The body (1100) and cap (1000) may be manufactured, for example, by injection molding, 3D printing, or assembling small parts manufactured by injection molding.

[0065] A retaining device (not shown) may be installed between the body (1100) and the cap (1000) to maintain the coupled state of the body (1100) and the cap (1000). As an example, the retaining device may include a protrusion and a groove. As another example, the retaining device may include a magnet and a metal member that adheres to the magnet.

[0066] Figure 4 is an exploded side view schematically showing the appearance of an aerosol generating device according to one embodiment.

[0067] Referring to FIG. 4, an aerosol generating device (100) according to one embodiment may include a cap (1000), a body (1100), a button (1200), and a cartridge (200).

[0068] At this time, each of the aerosol generating device (100) and the cartridge (200) may be identical or similar to the aerosol generating device (1) and the cartridge (19) of FIGS. 1 and 2. Duplicate descriptions are omitted below.

[0069] The cap (1000) can be detached from the body (1100) by being released from the body (1100). For example, the cap (1000) can be detached from the body (1100) in the +z direction. When the cap (1000) is detached from the body (1100), the upper portion of the body (1100), the button (1200), and the cartridge (200) can be exposed to the outside.

[0070] The button (1200) is positioned so that at least a portion thereof is exposed to the outside of the body (1100), and may serve to release the engagement relationship between the body (1100) and the cartridge (200) according to a user's input. For example, when a user's input is applied to the button (1200), the cartridge (200) may be detached from the body (1100).

[0071] The cartridge (200) stores an aerosol generating substance and can be detachably coupled to one end of the body (1100). At this time, the cartridge (200) is schematically illustrated, and the structure and shape of the cartridge (200) are not limited to those illustrated in FIG. 4.

[0072] According to one embodiment, the cartridge (200) may be applied as a component of an aerosol generating device (100) in combination with a body (1100) including a power source and / or a control unit. For example, a cartridge heater included in the cartridge (200) may be electrically connected to the body (1100) to receive power from the power source, and the power supply may be controlled by the control unit.

[0073] By supplying and controlling power to a heating element in an aerosol generating device including a cartridge (200), an aerosol can be generated from a liquid or gel-state aerosol generating material stored in the cartridge (200).

[0074] According to another example, the cartridge (200) can be combined with a body (1100) further including a receiving space for receiving an aerosol generating article and a heater for heating the aerosol generating article.

[0075] An aerosol generating device including a cartridge (200) can generate an aerosol not only by heating an aerosol generating material stored in the cartridge (200), but also by heating an inserted aerosol generating article. Accordingly, a hybrid type aerosol generating device can be implemented.

[0076] In FIG. 4, the cartridge (200) is depicted as approaching the side of the body (1100) and being coupled to the body (1100), but the coupling method of the cartridge (200) and the body (1100) is not limited thereto. For example, the cartridge (200) may be coupled to the body (1100) by approaching in the -z direction from a position spaced apart from the body (1100) in the +z direction, such as the cap (1000).

[0077] For convenience of explanation, the following description will focus on the structure in which the cartridge (200) approaches the side of the body (1100) and is coupled, and the cartridge (200) will be described in detail with reference to FIGS. 5a and 5b.

[0078] FIG. 5a is a front perspective view of a cartridge according to one embodiment, and FIG. 5b is a front exploded perspective view of the cartridge illustrated in FIG. 5a.

[0079] Referring to FIG. 5a, a cartridge (200) according to one embodiment may include a housing (2100) and a head (2200).

[0080] In general, the cartridge (200) is divided into an upper part and a lower part, and an aerosol generating substance is stored in the upper part, which functions as a liquid container, and then the upper part and the lower part are bonded to seal the container, thereby manufacturing the cartridge (200).

[0081] The cartridge (200) manufactured in this manner had the problem of being cumbersome to manufacture, as it had to go through a bonding step between the upper and lower parts during the manufacturing process. Furthermore, even if the bonding was secure, there was a possibility that aerosol-generating substances or aerosols could leak out of the cartridge through the gap that inevitably existed between the upper and lower parts.

[0082] To solve the above-described technical problem, the cartridge (200) according to one embodiment may include a housing (2100) that is not divided into an upper part and a lower part and extends to both ends of the cartridge (200) in the longitudinal direction of the cartridge (200).

[0083] The housing (2100) forms the exterior of the cartridge (200) and can store an aerosol generating substance. The housing (2100) may have a hollow cylindrical shape. Components of the cartridge (200) may be arranged inside the housing (2100) through one of the two ends (e.g., the lower end) that are open in the longitudinal direction of the housing (2100).

[0084] Components of the cartridge (200) may be pressed toward the interior of the housing (2100) in the longitudinal direction of the housing (2100). For example, components of the cartridge (200) may be pressed in the +z direction at a lower portion of the housing (2100) spaced apart from the housing (2100) in the -z direction. The components to be pressed may be force-fitted into the interior of the housing (2100). In this case, 'force-fit' may be used with the same meaning as press-fitting or force-fitting.

[0085] Components that are pressed toward the inside of the housing (2100) and forcefully fitted into the housing (2100) can be supported by the housing (2100). By forcefully fitting the components, the components can be firmly fixed inside the housing (2100) without using an adhesive, and a phenomenon in which a gap is formed between the inner wall of the housing (2100) and the components can be effectively prevented.

[0086] The housing (2100) may include an outlet (2110) for discharging aerosol generated inside the cartridge (200) to the outside of the cartridge (200). A portion of the outlet (2110) may be inserted into a body of an aerosol generating device (e.g., body (1100) of FIG. 4). A portion of the outlet (2110) inserted into the body may be connected to an airflow passage of the body.

[0087] The portion where the outlet (2110) and the airflow passage of the body are connected can be sealed. By connecting the outlet (2110) and the airflow passage of the body in a sealed manner, the aerosol can be prevented from leaking into a space other than the airflow passage of the body during the movement of the aerosol.

[0088] A cartridge (200) according to one embodiment may include a head (2200) for closing one end (e.g., the upper end) of the open ends of the housing (2100).

[0089] The head (2200) can serve as a cover for the housing (2100) to prevent the aerosol generating material stored in the storage space of the housing (2100) from overflowing to the outside of the housing (2100).

[0090] The head (2200) can be bonded by applying an adhesive that reacts to ultraviolet rays to the upper portion of the housing (2100) and using ultraviolet rays (UV). The head (2200) bonded to the housing (2100) is fixed to the upper portion of the housing (2100) so that even if an impact is applied to the cartridge (200), it does not fall from the housing (2100) and prevents the aerosol generating substance from overflowing from the housing (2100). However, the embodiment is not limited to the method in which the head (2200) is bonded to the upper portion of the housing (2100).

[0091] As another example, the housing (2100) and the head (2200) may not be manufactured as separate parts, but may be formed as a single piece by, for example, injection molding.

[0092] The head (2200) may include an airflow inlet (2200h) through which air from outside the cartridge (200) is introduced. Air introduced through the airflow inlet (2200h) may pass through the airflow passage of the cartridge (200) and reach the receiving portion, where it may be mixed with vaporized particles generated by atomization of the aerosol generating material.

[0093] Referring to FIG. 5b, the internal configurations of the cartridge (200) positioned inside the housing (2100) are illustrated along the longitudinal direction (e.g., z-axis direction) of the housing (2100).

[0094] A cartridge (200) according to one embodiment may include a housing (2100), a head (2200), a sealing portion (2300), a generating portion (2400), a receiving portion (2500), a clearance adjustment portion (2600), and a cover (2700).

[0095] The illustrated components may be coupled around the housing (2100) along the longitudinal direction of the housing (2100). For example, at the lower portion of the housing (2100), a sealing portion (2300) may be pressed toward the housing (2100) and positioned inside the housing (2100).

[0096] The generating unit (2400) may be accommodated in the receiving unit (2500), and the receiving unit (2500) may be pressed toward the housing and placed under the sealing unit (2300). Thereafter, the clearance adjustment unit (2600) and the cover (2700) may be sequentially pressed toward the housing (2100) and placed inside the housing. The cover (2700) may be inserted into the housing (2100) at least partially or entirely and may close one end of the housing (2100).

[0097] After the assembly of the lower portion of the housing (2100) is completed, an aerosol generating substance can be filled into the storage space of the housing (2100) in the upper portion of the housing (2100). Thereafter, the head (2200) can be coupled to the upper portion of the housing (2100) to close the other end of the housing (2100), thereby completing the final assembly of the cartridge (200). However, the order in which the cartridge (200) is assembled is not limited to the above-described order.

[0098] The housing (2100) may include a discharge port (2110) on one side, and the other side of the housing (2100) opposite the one side may include a concave groove in the direction in which the discharge port (2110) opens.

[0099] The concave groove of the housing (2100) may extend along the longitudinal direction of the housing (2100). To cover the concave groove of the housing (2100) from the side of the housing (2100), the housing (2100) may include a plate (2120) extending along the longitudinal direction of the housing (2100).

[0100] The plate (2120) can be ultrasonically bonded to the housing (2100) by approaching it in the +x direction from a position spaced apart from the housing (2100) in the -x direction. As a result, the plate (2120) is firmly fixed to the housing (2100) and may not fall off from the housing (2100) even if an impact is applied to the housing (2100). Ultrasonic bonding may refer to a manufacturing method of bonding the plate (2120) and the housing (2100) by instantly melting at least one of the plate (2120) and the housing (2100) by ultrasonic vibration. However, the embodiment is not limited to ultrasonic bonding and may include various methods by which the plate (2120) can be bonded to the housing (2100).

[0101] A plate (2120) coupled with a concave groove can form an intermediate airflow passage (2100p) together with the groove. Since the concave groove and the plate (2120) are included in the housing (2100), the intermediate airflow passage (2100p) can be treated as a configuration included in the housing (2100).

[0102] The intermediate airflow passage (2100p) can be connected to the airflow inlet (2200h) at a position corresponding to the airflow inlet (2200h) of the head (2200). The intermediate airflow passage (2100p) can be connected to one end (e.g., the lower portion) of the airflow inlet (2200h) to accommodate air moving along the airflow inlet (2200h).

[0103] The intermediate airflow passage (2100p) may extend along the longitudinal direction (e.g., z-axis direction) of the housing (2100), but the embodiment is not limited to the arrangement of the passage. Air introduced into the intermediate airflow passage (2100p) moves along the intermediate airflow passage (2100p) in the -z direction, and the moved air may pass through the groove formed in the sealing portion (2300) and the receiving portion (2500) and be introduced into the interior of the receiving portion (2500).

[0104] The intermediate airflow passage (2100p) may be arranged so as not to meet the storage space (2100s) in which the aerosol generating substance is stored within the housing (2100). Accordingly, the path through which the aerosol generating substance is transferred from the housing (2100) to the receiving portion (2500) and the path through which air is transferred may be separated and arranged separately.

[0105] In one embodiment, the intermediate airflow passage (2100p) may be formed between the plate (2120) and a concave groove of the housing (2100) by bonding the plate (2120) to a side surface of the housing (2100). As another example, the plate (2120) may be integrated with the housing (2100) such that the intermediate airflow passage (2100p) is formed as an area within the interior of the housing (2100).

[0106] The housing (2100) may include a storage space (2100s) in which an aerosol generating substance is stored. However, since the housing (2100) is hollow inside and both ends of the housing (2100) are open, the housing (2100) itself cannot store an aerosol generating substance.

[0107] A seal (2300) may be placed inside the housing (2100) to store the aerosol generating material. The seal (2300) may serve as a bottom wall of the storage space (2100s). At this time, the thickness of the seal may be 0.75 mm to 2 mm.

[0108] The sealing member (2300) may include at least one discharge port (2310) through which the aerosol generating material stored in the storage space (2100s) passes to move out of the storage space (2100s). In one embodiment, two discharge ports (2310) are arranged, but the embodiment is not limited to the number of discharge ports.

[0109] The housing (2100) has a hollow cylindrical shape, so that both ends are exposed to the outside, but the sealing portion (2300) having the discharge port (2310) formed therein can seal a portion of the interior of the housing (e.g., a portion of the lower portion of the storage space (2100s)). The aerosol generating material stored in the storage space (2100s) can move toward the outside of the storage space (2100s), i.e., the generating portion (2400), only through the discharge port (2310) formed in the sealing portion (2300). At this time, the discharge port (2310) can be distinguished from one end of the intermediate airflow passage (2100p) adjacent to the receiving portion (2500).

[0110] The sealing portion (2300) can be pressed into the interior of the housing (2100) through an open end (e.g., the lower end) of the housing (2100) and forcibly fitted into the interior of the housing (2100). The sealing portion (2300) pressed upward can move until it comes into contact with the inner wall of the housing (2100) facing downward, and the sealing portion (2300) that comes into contact with the inner wall of the housing (2100) can no longer move and be supported by the inner wall.

[0111] The forced fit of the seal (2300) due to pressurization can prevent a gap from forming between the edge of the seal (2300) and the inner wall of the housing (2100). To prevent a gap from forming through which aerosol generating substances can leak, at least a portion or all of the seal (2300) can be made of an elastic material such as rubber or silicone, but is not limited thereto.

[0112] The sealing member (2300) forcefully fitted into the housing (2100) can prevent the aerosol generating material stored in the storage space (2100s) from leaking out of the storage space (2100s) through a gap other than the discharge port (2310).

[0113] The generating unit (2400) is positioned below the sealing unit (2300) and can generate an aerosol from an aerosol generating substance that has moved outside the storage space (2100s). Aerosol refers to a suspended substance in which liquid and / or solid fine particles are dispersed in a gas. Therefore, the aerosol generated from the generating unit (2400) can refer to a state in which vaporized particles generated from the aerosol generating substance are mixed with air.

[0114] The generating unit (2400) can convert the phase of an aerosol generating material into a gaseous phase through vaporization and / or sublimation. For example, the generating unit (2400) can generate an aerosol by discharging a liquid and / or solid aerosol generating material into fine particles.

[0115] Specifically, the generator (2400) may include a wick (2410) and an atomizing element (2420). At this time, each of the wick (2410) and the atomizing element (2420) may be identical to or similar to each of the liquid delivery means and the cartridge heater (24) of FIGS. 1 and 2.

[0116] The wick (2410) can receive an aerosol generating substance supplied from the storage space (2100s) through the sealing portion (2300) and absorb the aerosol generating substance. The wick (2410) may have an elongated shape. For example, the wick (2410) may have a columnar shape extending in one direction. Specifically, the wick (2410) may have a polygonal columnar shape such as a cylindrical shape, a square columnar shape, a triangular columnar shape, etc., but is not limited to the above-described examples, and the wick (2410) may also have a roughly rod-shaped or needle-shaped shape.

[0117] The wick (2410) can absorb an aerosol-generating substance in one portion. The aerosol-generating substance absorbed by one portion of the wick (2410) can move to another portion of the wick (2410) due to capillary action. For example, the wick (2410) can absorb an aerosol-generating substance supplied from a storage space (2100s) through both ends, and the absorbed aerosol-generating substance can move to the center of the wick (2410). In this manner, the wick (2410) can transfer the aerosol-generating substance to an atomizing element.

[0118] The atomizing element (2420) can generate an aerosol from an aerosol-generating material absorbed by the wick (2410). For example, the atomizing element (2420) can be a heating element that heats the aerosol-generating material by generating heat. When the aerosol-generating material in contact with the heating element is heated by the heating element, an aerosol can be generated from the aerosol-generating material.

[0119] The heating element may be, but is not limited to, a metal heating wire, a metal heating plate, a ceramic heater, etc. The heating element may include a resistor having a temperature coefficient of resistance (TCR).

[0120] The heating element may be composed of a conductive filament, such as nichrome wire, and may be heated by an electric current supply. Alternatively, the heating element may be composed of a susceptor material that is heated by an induced magnetic field, and may be heated by an induced magnetic field generated by an induction coil positioned separately from the heating element.

[0121] As another example, the atomizing element (2420) may be an ultrasonic vibrator that generates an aerosol from an aerosol-generating substance by utilizing ultrasonic vibration. The ultrasonic vibration method may refer to a method of generating an aerosol by atomizing an aerosol-generating substance with ultrasonic vibrations generated by the vibrator.

[0122] The aerosol generating method of the atomizing element (2420) is not limited to the examples described above, and may include various methods of generating an aerosol from an aerosol generating material.

[0123] The atomizing element (2420) may be disposed adjacent to the wick (2410) and may be permanently or reversibly attached to the wick (2410) by not only a combination based on structural features such as being wound around the outer circumference of the center of the wick (2410), but also by applying, spraying, depositing, plating, immersing, painting, printing, 3D printing, using a device, etc., and may be disposed on the wick (2410). In addition, the atomizing element (2420) may be disposed on the wick (2410) by a method such as sintering the atomizing element (2420) together during the process of manufacturing the wick (2410).

[0124] The arrangement of the atomizing element (2420) is not limited to the examples described above, and may include various methods in which the atomizing element (2420) can be arranged on the wick (2410) while maintaining its function.

[0125] The aerosol generated by the atomizing element (2420) can travel along the airflow passage of the body (e.g., the body (1100) of FIG. 4). The aerosol that travels along the airflow passage of the body can pass through the aerosol generating article and be delivered to the user.

[0126] A cartridge (200) according to one embodiment may include a receiving portion (2500) that receives a generating portion (2400). In FIG. 5b, where the cartridge (200) is disassembled, the generating portion (2400) may be received within the receiving portion (2500) and mounted on the receiving portion (2500).

[0127] The receiving portion (2500) equipped with the generating portion (2400) can be forcefully fitted into the interior of the housing (2100) by being pressed into the interior of the housing (2100) through an open end (e.g., the lower portion) of the housing (2100). The receiving portion (2500) forcefully fitted into the interior of the housing (2100) can engage with the sealing portion (2300) at one portion.

[0128] The forced fit of the receptacle (2500) due to pressurization can prevent a gap from forming between the edge of the receptacle (2500) and the inner wall of the housing (2100). To prevent a gap from forming through which the aerosol generating substance can leak, at least a portion or all of the receptacle (2500) can be made of an elastic material such as rubber or silicone, but is not limited thereto.

[0129] A cartridge (200) according to one embodiment may include a clearance adjustment unit (2600). The clearance adjustment unit (2600) is arranged between the receiving portion (2500) and the cover (2700) and is configured to remove clearance existing between the receiving portion (2500) and the cover (2700).

[0130] When the cover (2700) is pressed against the clearance adjustment unit (2600), the clearance adjustment unit (2600) can press against the receiving unit (2500). Consequently, the clearance adjustment unit (2600) can enable the cover (2700) spaced apart from the receiving unit (2500) to support the receiving unit (2500) through the clearance adjustment unit (2600). At this time, the clearance adjustment unit (2600) may include a ring shape, but the embodiment is not limited thereto.

[0131] A cartridge (200) according to one embodiment may include a cover (2700). The cover (2700) may be positioned at an open end of the housing (2100) to close the end of the housing (2100). A portion of the cover (2700) may be inserted into the interior of the housing (2100).

[0132] Specifically, the cover (2700) can be pressed toward one end of the housing (2100), so that a portion of the cover (2700) can be forcefully fitted into the interior of the housing (2100) and supported by the housing. The cover (2700) forcefully fitted into the interior of the housing (2100) can come into contact with the clearance adjustment unit (2600).

[0133] The arrangement of the cover (2700) can prevent the sealing portion (2300) and the receiving portion (2500) disposed inside the housing (2100) from flowing downward without being supported by the inner wall of the housing (2100). Specifically, when the cover (2700) is firmly coupled to the housing (2100) and supported by the housing (2100), the cover (2700) can press the sealing portion (2300) and the receiving portion (2500) in a direction (e.g., +z direction or upward) toward the storage space (2100s) of the housing (2100).

[0134] This can be realized by the cover (2700) coming into contact with the clearance adjustment unit (2600) and pressurizing the clearance adjustment unit (2600), the clearance adjustment unit (2600) pressurizing the receiving unit (2500) that it has come into contact with, and the receiving unit (2500) pressurizing the sealing unit (2300) that it has come into contact with. The sealing unit (2300) located at the uppermost position among the pressurized components can be pressed in the opposite direction so as not to move any further by the inner wall of the housing (2100) facing downward as described above.

[0135] Accordingly, the sealing portion (2300) and the receiving portion (2500) can be supported without moving by being pressed upward by the cover (2700) and pressed downward by the inner wall of the housing (2100) facing downward, in addition to being supported by the housing (2100) at a certain position due to the forced fit.

[0136] In addition, since a part of the cover (2700) is forcefully fitted and the cover (2700) closes one end of the housing (2100), the cover (2700) can once again prevent leakage of aerosol generating substances and aerosol liquid that could not be prevented through forcefully fitting the sealing portion (2300) and the receiving portion (2500). That is, double sealing can be realized through the cover (2700). Additionally, triple sealing can be realized by placing a clearance adjustment portion (2600) between the receiving portion (2500) and the cover (2700).

[0137] Below, with reference to FIGS. 6a to 6c, the appearance of the internal components of the cartridge (200) when all of them are combined will be described.

[0138] Figures 6a to 6c are cross-sectional views of the cartridge illustrated in Figure 5a taken from different directions, respectively.

[0139] Specifically, Fig. 6a is a cross-sectional view of the cartridge cut along a plane parallel to the yz plane. Fig. 6b is a cross-sectional view of the cartridge cut along a plane parallel to the zx plane. Fig. 6c is a cross-sectional view of the cartridge cut along a plane parallel to the xy plane.

[0140] Referring to FIGS. 6A to 6C, a cartridge (200) according to one embodiment may include a housing (2100), a head (2200), a sealing portion (2300), a generating portion (2400), a receiving portion (2500), a clearance adjustment portion (2600), and a cover (2700).

[0141] At least one of the components of the cartridge (200) illustrated in FIGS. 6a to 6c may be identical or similar to at least one of the components of the cartridge (200) illustrated in FIGS. 5a and 5b, and any redundant description thereof will be omitted below.

[0142] Referring to FIGS. 6A to 6C, the internal space of the housing (2100) may include a first area (A1) in which a storage space (2100s) and a head (2200) are arranged, a second area (A2) in which a sealing portion (2300), a generating portion (2400), and a receiving portion (2500) are arranged, and a third area (A3) in which a clearance adjustment portion (2600) and a cover (2700) are arranged.

[0143] Since the first area (A1), the second area (A2), and the third area (A3) of the housing (2100) each have different inner diameters, a step may be formed within the housing (2100). The inner diameter of the portion extending from the first area (A1) to the second area (A2) may be enlarged. The inner diameter of the portion extending from the second area (A2) to the third area (A3) may also be enlarged.

[0144] In this specification, the inner wall of the housing (2100) facing downward from the first region (A1) to the second region (A2) is referred to as the first stage (2101), and the inner wall of the housing (2100) facing downward from the second region (A2) to the third region (A3) is referred to as the second stage (2102). In other words, the inner wall of the housing (2100) may include the first stage (2101) and the second stage (2102).

[0145] Areas adjacent to the edge at the top of the sealing portion (2300) can be supported by the first end (2101) of the housing (2100) while engaging with the first end (2101). That is, even if the sealing portion (2300) is pressed upward, the sealing portion (2300) can no longer move upward due to the first end (2101) and can be positioned at a portion in contact with the first end (2101).

[0146] Other areas of the upper portion of the sealing portion (2300) that do not come into contact with the first section (2101) protrude toward the first area (A1) of the housing (2100) and are inserted or force-fitted into the inner wall of the housing (2100), so that the sealing portion (2300) can be firmly coupled to the interior of the housing (2100).

[0147] The areas adjacent to the edge at the bottom of the receiving portion (2500) may be arranged substantially parallel to the second end (2102) of the housing (2100). However, this is not limited to this, and there may be a step between the second end (2102) and the areas adjacent to the edge at the bottom of the receiving portion (2500).

[0148] The clearance adjustment unit (2600) is arranged on the upper part of the cover (2700) and contacts the areas adjacent to the edge of the receiving portion (2500) and the second stage (2102), so that the cover (2700) can pressurize the receiving portion (2500) through the clearance adjustment unit (2600) without directly contacting the step existing between the second stage (2102) and the receiving portion (2500).

[0149] In addition, the clearance adjustment unit (2600) can block a gap that may occur between the inner wall of the housing (2100) and the receiving portion (2500) around the second stage (2102) depending on the difference in inner diameter between the second area (A2) and the third area (A3) of the housing (2100), thereby preventing leakage of aerosol moving from the receiving portion (2500) to the outlet (2110).

[0150] The sealing portion (2300) and the receiving portion (2500) can be firmly joined to each other by force fitting and pressurization. When the sealing portion (2300) and the receiving portion (2500) are interlocked, a generation space (2510) surrounding the generation portion (2400) can be formed.

[0151] A sealing portion (2300) may be arranged at the upper portion of the generation space (2510), and a receiving portion (2500) may be arranged at the side and lower portions. The aerosol generating material stored in the storage space (2100s) may be introduced into the generation space (2510) through the discharge port (2310) of the sealing portion (2300).

[0152] In the generation space (2510), the aerosol-generating material is atomized, and the vaporized particles thus generated can be mixed with air to form an aerosol. In this case, in order for air to be introduced into the generation space (2510), air from outside the cartridge (200) must move to the generation space (2510) along the airflow passage arranged inside the cartridge (200).

[0153] As described above, air from outside the cartridge (200) is introduced into the interior of the cartridge (200) through the airflow inlet (2200h) of the head (2200), and air passing through the airflow inlet (2200h) can move along the intermediate airflow passage (2100p) surrounded by the inner wall of the housing (2100) and the plate (2120).

[0154] Thereafter, the air can reach the production space (2510) by passing through the first lower passage formed by being surrounded by the first airflow groove (2320) formed in the sealing portion (2300) and the inner wall of the housing (2100), and the second lower passage formed by being surrounded by the second airflow groove (2520) formed in the receiving portion (2500) and the inner wall of the housing (2100). The first lower passage and the second lower passage can be connected in the z-axis direction to form a lower airflow passage together.

[0155] Meanwhile, a concave portion (2330) and a convex portion (2530) may be arranged between the sealing portion (2300) and the receiving portion (2500) to prevent leakage through the gap between the two components.

[0156] The convex portion (2530) interlocked with the concave portion (2330) can prevent the aerosol generating material or the aerosol generated in the generating space from leaking through the gap between the sealing portion (2300) and the receiving portion (2500).

[0157] Hereinafter, with reference to FIGS. 7a and 7b, the lower components of the cartridge (200) arranged in the second area (A2) and the third area (A3) inside the housing (2100) will be described.

[0158] Figures 7a and 7b are perspective views of the lower components of a cartridge according to one embodiment.

[0159] Specifically, FIG. 7a is a front perspective view of the lower components of the cartridge, and FIG. 7b is a rear exploded perspective view of the lower components of the cartridge.

[0160] Referring to FIGS. 7a and 7b, a cartridge (200) according to one embodiment may include a sealing portion (2300), a generating portion (2400), a receiving portion (2500), a clearance adjustment portion (2600), and a cover (2700).

[0161] At least one of the components of the cartridge (200) illustrated in FIGS. 7a and 7b may be identical or similar to at least one of the components of the cartridge (200) illustrated in FIGS. 6a to 6c, and any redundant description thereof will be omitted below.

[0162] Based on the receiving part (2500), a generating part (2400) can be received inside the receiving part (2500), a sealing part (2300) can be combined on the upper part of the receiving part (2500), and a clearance adjustment part (2600) and a cover (2700) can be combined on the lower part of the receiving part (2500).

[0163] Based on the longitudinal direction of the cartridge (200) (e.g., z-axis direction), the ratio of the length of the lower components of the cartridge (200) to the length of the cartridge (200) may be 1:3.5 to 1:4. For example, the length of the lower components of the cartridge (200) may be 8 mm to 10 mm, and the length of the cartridge (200) may be 28 mm to 40 mm. At this time, the starting point of the length measurement may be the lower surface of the cover (2700), and the end point of the length measurement may be the uppermost surface of the sealing portion (2300) and the upper surface of the head (e.g., the head (2200) of FIGS. 6A to 6C), respectively.

[0164] The two discharge ports (2310) of the sealing portion (2300) may be positioned at positions corresponding to the receiving grooves of the receiving portion (2500) that receive the generating portion (2400). For example, the discharge ports (2310) may be positioned at the top of the generating space (2510) so that the aerosol generating material passing through the discharge ports (2310) can be directly introduced into the receiving grooves of the receiving portion (2500).

[0165] The sealing portion (2300) may include a first airflow groove (2320), and the receiving portion (2500) may include a second airflow groove (2520). Specifically, when the sealing portion (2300) and the receiving portion (2500) are not inserted into the interior of the housing (2100), the sealing portion (2300) and the receiving portion (2500) may include airflow grooves that simply guide the movement of air, rather than airflow passages.

[0166] When the open portions of the first airflow groove (2320) and the second airflow groove (2520) are closed by the inner wall of the housing (2100), a lower airflow passage that is open only in the z-axis direction can be formed by being surrounded by the first airflow groove (2320) and the second airflow groove (2520) and the inner wall of the housing (2100).

[0167] An airflow groove, rather than an airflow passage, is arranged in the sealing portion (2300) and the receiving portion (2500), and as the airflow groove forms an airflow passage with the inner wall of the housing (2100), the inner diameter of the airflow passage is enlarged, allowing more airflow to be introduced into the generation space (2510).

[0168] The receiving portion (2500) may include an inlet (2540) for introducing airflow into the production space (2510). At this time, the second airflow groove (2520) is in fluid communication with the inlet (2540) and may extend from the inlet (2540) to guide the movement of air to the inlet (2540), thereby allowing air to smoothly be introduced into the production space (2510). At this time, 'fluid communication' may mean that elements are connected or communicated so that a fluid such as air can pass through and flow.

[0169] The receiving portion (2500) may include an outlet (2550) for discharging the aerosol generated in the generating space (2510) to the outside of the receiving portion (2500). The outlet (2550) may be positioned corresponding to the outlet of the housing (2100) (e.g., the outlet (2110) of FIGS. 6A to 6C) and may be connected to the outlet. The aerosol may pass through the outlet (2550) and the outlet to be discharged to the outside of the cartridge (200).

[0170] Hereinafter, with reference to FIGS. 8a to 8c, the sealing portion (2300), the generating portion (2400), and the receiving portion (2500) arranged in the second area (A2) inside the housing (2100) will be described.

[0171] FIGS. 8A to 8C are drawings for explaining a structure in which a sealing portion, a generating portion, and a receiving portion are combined and applied to a cartridge according to one embodiment.

[0172] Specifically, Fig. 8a is a front exploded perspective view showing a seal (2300) separated from the structure. Fig. 8b is a perspective view of the structure viewed from below in the +z direction. Fig. 8c is a cross-sectional view of the structure cut along a plane parallel to the zx plane.

[0173] Referring to FIGS. 8A to 8C, a cartridge (200) according to one embodiment may include a sealing portion (2300), a generating portion (2400), and a receiving portion (2500).

[0174] Referring to FIG. 8A, the sealing portion (2300) may include a peripheral portion (2301) in which two discharge ports (2310) are arranged and a central portion (2302) between the two discharge ports (2310). The peripheral portion (2301) may be made of an elastic material such as rubber or silicone, while the central portion (2302) may be made of a material having relatively greater rigidity than the peripheral portion (2301), such as plastic. The peripheral portion (2301) and the central portion (2302) made of different materials may be double-injected using a double injection molding method to form a single sealing portion (2300).

[0175] The receiving groove of the receiving portion (2500), which receives the generating portion (2400) and forms the generating space (2510), may include a shape in which the width of the groove (e.g., the length in the x-axis direction) is larger in the central portion than in the peripheral portion of the receiving portion (2500). Accordingly, the upper portion of the receiving portion (2500) can support a wider area of ​​the sealing portion (2300) in the peripheral portion where the groove is formed smaller than in the central portion where the groove is formed larger.

[0176] According to this structure, the central portion (2302) of the sealing portion (2300) does not have a separate support structure at the bottom and the discharge port (2310) is not arranged, so the aerosol generating material can be located at the top of the central portion (2302), and thus the central portion (2302) of the sealing portion (2300) can sag downward compared to the peripheral portion (2301).

[0177] At this time, when the sealing part (2300) is formed by double injection using different materials, the center part (2302) of the sealing part (2300) has greater rigidity than the peripheral part (2301), so the phenomenon of the center of the main sealing part sagging downward can be prevented.

[0178] However, the embodiment is not limited to the materials of the peripheral portion (2301) and the central portion (2302). The sealing portion (2300) can be formed using various materials that satisfy the condition that the rigidity of the central portion (2302) is greater than that of the peripheral portion (2301) of the sealing portion (2300).

[0179] Referring to FIGS. 8A and 8B, an aerosol generating substance passing through the discharge port (2310) of the sealing portion (2300) can flow into the peripheral portion of the receiving groove of the receiving portion (2500). When the aerosol generating substance moves from the peripheral portion of the wick (2410) disposed in the peripheral portion to the center of the wick (2410), it can be heated by the atomizing element (2420) wrapped around the center of the wick (2410).

[0180] The heating element (2420) may be a heating coil. Both ends of the coil may be connected to terminals disposed on a cover (e.g., cover (2700) of FIGS. 6A to 6C) through holes formed in the lower portion of the receiving portion (2500).

[0181] The receiving portion (2500) may have a lower portion protruding toward the cover so that it can be inserted into an internal space formed in the cover. The protruding portion of the receiving portion (2500) may be inserted into and supported by the internal space of the cover, and both ends of the coil may pass through the protruding portion of the receiving portion (2500) and be connected to the terminals of the cover.

[0182] Referring to FIGS. 8A to 8C, a convex portion (2530) may be arranged on the upper portion of the receiving portion (2500). To enhance the leakage prevention effect of the convex portion (2530), the convex portion (2530) may be arranged on a portion adjacent to the edge on the upper portion of the receiving portion (2500) and may be arranged in the form of a closed ring on the upper portion of the receiving portion (2500).

[0183] In one embodiment, the convex portion (2530) is expressed as pointed, but the embodiment is not limited to the shapes of the concave portion (2330) and the convex portion (2530). The convex portion (2530) may include various shapes that protrude toward the opposite configuration, and the concave portion (2330) may include a shape corresponding to the convex portion (2530) in order to engage with the convex portion (2530).

[0184] In addition, the embodiment is not limited to the arrangement of the concave portion (2330) and the convex portion (2530). In one embodiment, the concave portion (2330) is arranged in the sealing portion (2300) and the convex portion (2530) is arranged in the receiving portion (2500). However, a person skilled in the art can easily understand that the concave portion (2330) can be arranged in the receiving portion (2500) and the convex portion (2530) can be arranged in the sealing portion (2300).

[0185] The convex portion (2530) may be formed integrally with the sealing portion (2300) or the receiving portion (2500). For example, the convex portion (2530) may be formed integrally with the receiving portion (2500) by injection molding. By being formed integrally, the leakage prevention effect of the concave portion (2330) and the convex portion (2530) may be enhanced, and the configuration included in the cartridge (200) may be simplified. However, the embodiment is not limited thereto, and the convex portion (2530) may be separated into a separate configuration rather than being included in the sealing portion (2300) and the receiving portion (2500).

[0186] Referring to FIG. 8c, the sealing portion (2300) may include an extension portion (2340) extending toward the creation space (2510). The extension portion (2340) may be supported by an inner wall (2511) of the receiving portion (2500) forming the creation space (2510).

[0187] As the extension part (2340) is engaged with the inner wall (2511) of the receiving part (2500), the aerosol generating material or aerosol can be prevented from leaking into the gap between the sealing part (2300) and the receiving part (2500) compared to the case where a separate extension part (2340) is not arranged and the lower part of the sealing part (2300) is flat.

[0188] Additionally, since the thickness of the sealing portion (2300) (e.g., length in the z-axis direction) increases in the portion where the extension portion (2340) is placed, the phenomenon of the central portion of the sealing portion (2300) sagging downward due to the weight of the aerosol generating material can be alleviated.

[0189] The extension (2340) can extend to a point where it does not come into contact with the generation unit (2400). That is, the extension (2340) can allow the generation unit (2400) to be placed inside the generation space (2510) without interfering with the placement of the generation unit (2400).

[0190] Additionally, the extension (2340) can extend to a point where it does not obscure at least a portion of the inlet (2540) and the outlet (2550). Accordingly, even though the extension (2340) exists, the external airflow or aerosol can move along the first airflow groove (2320), the second airflow groove (2520), the inlet (2540), the generation space (2510), and the outlet (2550) without being obstructed by the extension (2340).

[0191] Meanwhile, the lower portion of the second airflow groove (2520) may include an inclined surface (2521) inclined with respect to the direction in which the inlet (2540) is opened. The inclined surface (2521) may extend to the lower portion of the inlet (2540), so that a micro-space (2522) may be formed at the lower portion of the inlet (2540) in the second airflow groove (2520).

[0192] In the micro-space (2522), turbulence may be formed as air flows along the second airflow groove (2520) or the airflow path. As turbulence is formed in the micro-space (2522), the atomization amount of the aerosol may be improved.

[0193] FIGS. 9A and 9B are drawings for explaining a seal applied to a cartridge according to one embodiment.

[0194] Specifically, Fig. 9a is a perspective view of the sealing portion viewed from below in the +z direction. Fig. 9b is a cross-sectional view of the structure in which the generating portion is coupled to the sealing portion, cut along a plane parallel to the zx plane.

[0195] Referring to FIGS. 9a and 9b, the sealing portion (2300) may include a discharge port (2310), a first airflow groove (2320), a concave portion (2330), an extension portion (2340), and a contact portion (2350).

[0196] The concave portion (2330) may be formed with a groove having a shape corresponding to the convex portion (e.g., the convex portion (2530) of FIGS. 8A to 8C). When the convex portion is engaged with the concave portion (2330), leakage of aerosol generating substances and aerosol through the gap between the sealing portion (2300) and the receiving portion can be prevented.

[0197] The contact portion (2350) can extend toward the receiving groove of the receiving portion (2500) in which the generating portion (2400) is received and support the wick (2410) of the generating portion (2400). The contact surface of the contact portion (2350) in contact with the wick (2410) can include a shape corresponding to the shape of the wick (2410) so as to surround a portion of the wick (2410).

[0198] The contact portion (2350) may be positioned between the discharge port (2310) and the extension portion (2340). Two contact portions (2350) may be positioned so as to support the cylindrical wick (2410) at both peripheries. In this case, the two contact portions (2350) may be positioned sufficiently apart from each other so as not to interfere with the atomizing element (2420) wound around the center of the wick (2410).

[0199] The contact portion (2350) may extend further than the extension portion (2340) extends toward the creation space (2510) to support the wick (2410).

[0200] Hereinafter, with reference to FIGS. 10a to 10c, the clearance adjustment unit (2600) and cover (2700) arranged in the third area (A3) inside the housing (2100) will be described.

[0201] FIGS. 10A to 10C are drawings for explaining a structure in which a generating unit, a clearance adjusting unit, and a cover are combined to be applied to a cartridge according to one embodiment.

[0202] Specifically, Fig. 10a is a front perspective view of the structure. Fig. 10b is an exploded perspective view showing the structure with the generating unit (2400) omitted and the clearance adjustment unit (2600) and the cover (2700) separated from each other. Fig. 10c is a perspective view of the structure shown in Fig. 10a with the generating unit (2400) omitted, viewed from below in the +z direction.

[0203] Referring to FIGS. 10A to 10C, a cartridge (200) according to one embodiment may include a generating unit (2400), a clearance adjustment unit (2600), and a cover (2700).

[0204] The clearance adjustment unit (2600) may be coupled to the upper portion of the cover (2700). The cover (2700) may include a guide protruding in the +z-axis direction to guide the coupling of the clearance adjustment unit (2600). The guide may have a shape corresponding to the shape of the hole formed in the ring-shaped clearance adjustment unit (2600). When the clearance adjustment unit (2600) is coupled to the cover (2700), the guide may be positioned inside the hole of the clearance adjustment unit (2600).

[0205] The cover (2700) may be opened upwardly to accommodate a portion (e.g., a lower portion) of a receiving portion (e.g., a receiving portion (2500) of FIGS. 8A to 8C). Through the open portion, the cover (2700) may engage with the receiving portion to support the receiving portion. In addition, the cover (2700) may contact the clearance adjustment unit (2600) to pressurize the receiving portion.

[0206] The cover (2700) may include a terminal (2710) for supplying power from the outside of the cartridge (200). For example, the terminal (2710) connected to the external power source or control unit of the cartridge (200) may contact both ends of the coil (2420) wound around the wick (2410) of the generator (2400) to supply power to the coil (2420).

[0207] The terminal (2710) may be formed by insert injection into the cover (2700) so as to penetrate the cover (2700). That is, since the cover (2700) and the terminal (2710) are formed integrally, the manufacturing process is simplified and the internal configuration of the cartridge (200) can be simplified. However, the manner in which the terminal (2710) is arranged in the cover (2700) is not limited to the above-described example.

[0208] In addition to being supported by the housing (2100) by being pressed against and forcibly fitted toward the open end of the housing (2100), the cover (2700) may include one or more protrusions (2720) that can engage with the housing (2100).

[0209] The protrusion (2720) can be inserted into one or more insertion holes formed in the lower portion of the housing (2100). The protrusion (2720) inserted into the insertion hole is supported by the insertion hole and does not move, so that the cover (2700) can be firmly coupled to the housing (2100). The number of insertion holes may be the same as the number of protrusions.

[0210] Below, with reference to FIG. 11, a protrusion that firmly connects the cover (2700) and the housing (2100) will be described in detail.

[0211] Fig. 11 is a cross-sectional view of the lower portion of the cartridge shown in Fig. 6c to illustrate the protrusion of the cover.

[0212] Referring to FIG. 11, a cover (2700) of a cartridge (200) according to one embodiment may include a terminal (2710) and a protrusion (2720).

[0213] As described above with reference to FIGS. 10A to 10C, the housing (2100) includes an insertion hole (2130), and the protrusion (2720) of the cover (2700) can be inserted into the insertion hole (2130).

[0214] When the cover (2700) is pressed upward (e.g., in the +z direction) or toward the storage space (2100s) from a position away from one end of the housing (2100) by the user, and the protrusion (2720) of the cover (2700) is inserted into the insertion hole (2130), the movement of the cover (2700) can be restricted by the protrusion (2720) having a cross-section of a right triangle.

[0215] In this state, the cover (2700) cannot move downward, and the cover (2700) is maintained in a state of being pressed upward by the engagement of the protrusion (2720) and the insertion hole (2130). Accordingly, the cover (2700) can be firmly coupled to the housing (2100).

[0216] Accordingly, even if an impact is applied to the cartridge (200), the cover (2700) does not separate from the housing (2100), and one end of the housing (2100) can be firmly closed so that the components located inside the housing (2100) do not escape to the outside of the housing (2100).

[0217] However, the embodiment is not limited to the shape of the protrusion (2720) and the insertion hole (2130). As another example, a protrusion and a groove structure may be used for the connection. As another example, a configuration that penetrates the interior of the housing (2100) from the outside of the housing (2100) and presses the side of the cover (2700) may be used for the connection. As another example, a bolt and a nut may be used for the connection.

[0218] According to the cartridge (200) and the aerosol generating device including the same according to the embodiments, since the components are placed inside the housing (2100) by pressurizing and forcibly fitting them, there is no need to separately use a material with excellent adhesive strength, and accordingly, the manufacturing of the cartridge (200) is simple and the manufacturing cost can be reduced.

[0219] In addition, according to the cartridge (200) and the aerosol generating device including the same according to the embodiments, the sealing effect inside the cartridge (200) is improved by force fitting, so that leakage of the aerosol generating material can be prevented.

[0220] In addition, according to the cartridge (200) and the aerosol generating device including the same according to the embodiments, the sealing effect can be maximized by pressurizing and doubly sealing the components by placing the cover as well as forcibly fitting them.

[0221] FIG. 12 is a block diagram of an aerosol generating device according to one embodiment of the present disclosure.

[0222] The aerosol generating device (1) may include a power source (11), a control unit (12), a sensor (13), an output unit (14), an input unit (15), a communication unit (16), a memory (17), and at least one heater (18, 24). However, the internal structure of the aerosol generating device (1) is not limited to that illustrated in Fig. 12. That is, a person having ordinary skill in the art related to the present embodiment will understand that, depending on the design of the aerosol generating device (1), some of the components illustrated in Fig. 12 may be omitted or new components may be added.

[0223] The sensor (13) can detect the status of the aerosol generating device (1) or the status around the aerosol generating device (1) and transmit the detected information to the control unit (12). Based on the detected information, the control unit (12) can control the aerosol generating device (1) so that various functions such as controlling the operation of the cartridge heater (24) and / or heater (18), restricting smoking, determining whether a stick (S) and / or cartridge (19) is inserted, and displaying a notification are performed.

[0224] The sensor (13) may include at least one of a temperature sensor (131), a puff sensor (132), an insertion detection sensor (133), a reuse detection sensor (134), a cartridge detection sensor (135), a cap detection sensor (136), and a movement detection sensor (137).

[0225] The temperature sensor (131) can detect the temperature at which the cartridge heater (24) and / or the heater (18) is heated. The aerosol generating device (1) may include a separate temperature sensor that detects the temperature of the cartridge heater (24) and / or the heater (18), or the cartridge heater (24) and / or the heater (18) itself may serve as the temperature sensor.

[0226] The temperature sensor (131) can output a signal corresponding to the temperature of the cartridge heater (24) and / or the heater (18). For example, the temperature sensor (131) can include a resistance element whose resistance value changes in response to a change in the temperature of the cartridge heater (24) and / or the heater (18). It can be implemented by a thermistor, which is an element that utilizes the property of changing resistance depending on temperature. At this time, the temperature sensor (131) can output a signal corresponding to the resistance value of the resistance element as a signal corresponding to the temperature of the cartridge heater (24) and / or the heater (18). For example, the temperature sensor (131) can be configured as a sensor that detects the resistance value of the cartridge heater (24) and / or the heater (18). At this time, the temperature sensor (131) can output a signal corresponding to the resistance value of the cartridge heater (24) and / or the heater (18) as a signal corresponding to the temperature of the cartridge heater (24) and / or the heater (18).

[0227] A temperature sensor (131) may be placed around the power source (11) to monitor the temperature of the power source (11). The temperature sensor (131) may be placed adjacent to the power source (11). For example, the temperature sensor (131) may be attached to one side of a battery, which is the power source (11). For example, the temperature sensor (131) may be mounted on one side of a printed circuit board.

[0228] A temperature sensor (131) is placed inside the body (10) and can detect the internal temperature of the body (10).

[0229] The puff sensor (132) can detect the user's puff based on various physical changes in the airflow path. The puff sensor (132) can output a signal corresponding to the puff. For example, the puff sensor (132) can be a pressure sensor. The puff sensor (132) can output a signal corresponding to the internal pressure of the aerosol generating device. Here, the internal pressure of the aerosol generating device (1) can correspond to the pressure of the airflow path through which the gas flows. The puff sensor (132) can be arranged in correspondence to the airflow path through which the gas flows in the aerosol generating device (1).

[0230] The insertion detection sensor (133) can detect insertion and / or removal of the stick (S). The insertion detection sensor (133) can detect a signal change regarding the insertion and / or removal of the stick (S). The insertion detection sensor (133) can be installed around the insertion space. The insertion detection sensor (133) can detect the insertion and / or removal of the stick (S) according to a change in the permittivity inside the insertion space. For example, the insertion detection sensor (133) can be an inductive sensor and / or a capacitance sensor.

[0231] An inductive sensor may include at least one coil. The coil of the inductive sensor may be positioned adjacent to an insertion space. For example, when a magnetic field changes around a current-flowing coil, the characteristics of the current flowing in the coil may change according to Faraday's law of electromagnetic induction. Here, the characteristics of the current flowing in the coil may include the frequency of the alternating current, the current value, the voltage value, the inductance value, the impedance value, etc.

[0232] An inductive sensor can output a signal corresponding to the characteristics of the current flowing through the coil. For example, an inductive sensor can output a signal corresponding to the inductance value of the coil.

[0233] A capacitance sensor may include a conductor. The conductor of the capacitance sensor may be positioned adjacent to the insertion space. The capacitance sensor may output a signal corresponding to the electromagnetic properties of the surroundings, for example, the electrostatic capacitance around the conductor. For example, when a stick (S) including a wrapper made of a metallic material is inserted into the insertion space, the electromagnetic properties around the conductor may be changed by the wrapper of the stick (S).

[0234] A reuse detection sensor (134) can detect whether the stick (S) has been reused. The reuse detection sensor (134) may be a color sensor. The color sensor can detect the color of the stick (S). The color sensor can detect the color of a portion of a wrapper that wraps the outside of the stick (S). The color sensor can detect a value for an optical characteristic corresponding to the color of an object based on light reflected from the object. For example, the optical characteristic may be a wavelength of light. The color sensor may be implemented as a single component with the proximity sensor, or may be implemented as a separate component distinct from the proximity sensor.

[0235] At least some of the wrappers constituting the stick (S) may change color due to the aerosol. The reuse detection sensor (134) may be positioned corresponding to a position where at least some of the wrappers whose color changes due to the aerosol are disposed when the stick (S) is inserted into the insertion space. For example, before the stick (S) is used by a user, the color of at least some of the wrappers may be a first color. At this time, as at least some of the wrappers are wetted by the aerosol generated by the aerosol generating device (1) while passing through the stick (S), the color of at least some of the wrappers may change to a second color. Meanwhile, the color of at least some of the wrappers may be maintained at the second color after changing from the first color to the second color.

[0236] The cartridge detection sensor (135) can detect the mounting and / or removal of the cartridge (19). The cartridge detection sensor (135) can be implemented by an inductance-based sensor, a capacitive sensor, a resistance sensor, a Hall sensor (hall IC) using the Hall effect, etc.

[0237] The cap detection sensor (136) can detect the attachment and / or removal of the cap. When the cap is separated from the body (10), the cartridge (19) and a portion of the body (10) covered by the cap may be exposed to the outside. The cap detection sensor (136) can be implemented by a contact sensor, a hall sensor (hall IC), an optical sensor, or the like.

[0238] A motion detection sensor (137) can detect the movement of the aerosol generating device. The motion detection sensor (137) can be implemented with at least one of an acceleration sensor and a gyro sensor.

[0239] In addition to the sensors (131 to 137) described above, the sensor (13) may further include at least one of a humidity sensor, a pressure sensor, a magnetic sensor, a position sensor (GPS), and a proximity sensor. Since the functions of each sensor can be intuitively inferred by a person skilled in the art from its name, a detailed description thereof may be omitted.

[0240] The output unit (14) can output information on the status of the aerosol generating device (1) and provide it to the user. The output unit (14) may include at least one of a display (141), a haptic unit (142), and an audio output unit (143), but is not limited thereto. When the display (141) and the touch pad form a layered structure to form a touch screen, the display (141) can be used as an input device in addition to an output device.

[0241] The display (141) can visually provide information about the aerosol generating device (1) to the user. For example, the information about the aerosol generating device (1) may refer to various information such as the charging / discharging status of the power supply (11) of the aerosol generating device (1), the preheating status of the heater (18), the insertion / removal status of the stick (S) and / or cartridge (19), the mounting / removal status of the cap, or the status in which the use of the aerosol generating device (1) is restricted (e.g., detection of an abnormal item), and the display (141) can output the above information to the outside. For example, the display (141) may be in the form of an LED light-emitting element. For example, the display (141) may be a liquid crystal display panel (LCD), an organic light-emitting display panel (OLED), etc.

[0242] The haptic unit (142) can provide tactile information about the aerosol generating device (1) to the user by converting an electrical signal into a mechanical stimulus or an electrical stimulus. For example, the haptic unit (142) can generate a vibration corresponding to the completion of the initial preheating when initial power is supplied to the cartridge heater (24) and / or heater (18) for a set period of time. The haptic unit (142) can include a vibration motor, a piezoelectric element, or an electrical stimulation device.

[0243] The acoustic output unit (143) can provide information about the aerosol generating device (1) to the user audibly. For example, the acoustic output unit (143) can convert an electrical signal into an acoustic signal and output it to the outside.

[0244] The power source (11) can supply power used to operate the aerosol generating device (1). The power source (11) can supply power so that the cartridge heater (24) and / or the heater (18) can be heated. In addition, the power source (11) can supply power required for the operation of other components provided in the aerosol generating device (1), such as a sensor (13), an output unit (14), an input unit (15), a communication unit (16), and a memory (17). The power source (11) can be a rechargeable battery or a disposable battery. For example, the power source (11) can be a lithium polymer (LiPoly) battery, but is not limited thereto.

[0245] Although not shown in FIG. 12, the aerosol generating device (1) may further include a power protection circuit. The power protection circuit may be electrically connected to the power source (11) and may include a switching element.

[0246] The power protection circuit can block the power supply (11) according to certain conditions. For example, the power protection circuit can block the power supply (11) when the voltage level of the power supply (11) is higher than a first voltage corresponding to overcharge. For example, the power protection circuit can block the power supply (11) when the voltage level of the power supply (11) is lower than a second voltage corresponding to overdischarge.

[0247] The heater (18) can receive power from the power source (11) and heat the medium or aerosol generating material within the stick (S). Although not illustrated in FIG. 12, the aerosol generating device (1) may further include a power conversion circuit (e.g., a DC / DC converter) that converts the power of the power source (11) and supplies it to the cartridge heater (24) and / or the heater (18). In addition, when the aerosol generating device (1) generates the aerosol by induction heating, the aerosol generating device (1) may further include a DC / AC converter that converts the direct current power of the power source (11) into alternating current power.

[0248] The control unit (12), sensor (13), output unit (14), input unit (15), communication unit (16), and memory (17) can receive power from the power source (11) and perform their functions. Although not illustrated in FIG. 12, the device may further include a power conversion circuit, for example, an LDO (low dropout) circuit or a voltage regulator circuit, that converts the power of the power source (11) and supplies it to each component. In addition, although not illustrated in FIG. 12, a noise filter may be provided between the power source (11) and the heater (18). The noise filter may be a low pass filter. The low pass filter may include at least one inductor and a capacitor. The cutoff frequency of the low pass filter may correspond to the frequency of the high frequency switching current applied from the power source (11) to the heater (18). The low pass filter can prevent high frequency noise components from being applied to a sensor (13), such as an insertion detection sensor (133).

[0249] In one embodiment, the cartridge heater (24) and / or heater (18) may be formed of any suitable electrically resistive material. For example, suitable electrically resistive materials may be metals or metal alloys including, but not limited to, titanium, zirconium, tantalum, platinum, nickel, cobalt, chromium, hafnium, niobium, molybdenum, tungsten, tin, gallium, manganese, iron, copper, stainless steel, nichrome, and the like. Additionally, the heater (18) may be implemented as, but not limited to, a metal heating wire, a metal heating plate having electrically conductive tracks arranged thereon, a ceramic heating element, and the like.

[0250] In another embodiment, the heater (18) may be an induction heater. For example, the heater (18) may include a susceptor that heats the aerosol generating material by generating heat through a magnetic field applied by a coil.

[0251] The input unit (15) can receive information input from a user or output information to the user. For example, the input unit (15) can be a touch panel. The touch panel can include at least one touch sensor that detects touch. For example, the touch sensor can include, but is not limited to, a capacitive touch sensor, a resistive touch sensor, a surface acoustic wave touch sensor, an infrared touch sensor, etc.

[0252] The display (141) and the touch panel may be implemented as a single panel. For example, the touch panel may be inserted into the display (141) (on-cell type or in-cell type). For example, the touch panel may be added on the display panel (add-on type).

[0253] Meanwhile, the input unit (15) may include, but is not limited to, buttons, key pads, dome switches, jog wheels, jog switches, etc.

[0254] The memory (17) is hardware that stores various data processed in the aerosol generating device (1), and can store data processed and data to be processed in the control unit (12).

The processor may be implemented as an array of multiple logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory storing a program executable by the microprocessor. Furthermore, it will be understood by those skilled in the art that the present embodiment may be implemented as other types of hardware.

[0260] The control unit (12) can control the temperature of the heater (18) by controlling the supply of power from the power source (11) to the heater (18). The control unit (12) can control the temperature of the cartridge heater (24) and / or the heater (18) based on the temperature of the cartridge heater (24) and / or the heater (18) sensed by the temperature sensor (131). The control unit (12) can adjust the power supplied to the cartridge heater (24) and / or the heater (18) based on the temperature of the cartridge heater (24) and / or the heater (18). For example, the control unit (12) can determine a target temperature for the cartridge heater (24) and / or the heater (18) based on a temperature profile stored in the memory (17).

[0261] The aerosol generating device (1) may include a power supply circuit (not shown) electrically connected to the power supply (11) between the power supply (11) and the cartridge heater (24) and / or the heater (18).

[0262] The control unit (12) can control power supply by controlling the switching of the switching elements of the power supply circuit. The power supply circuit may be an inverter that converts direct current power output from the power source (11) into alternating current power. For example, the inverter may be configured as a full-bridge circuit or a half-bridge circuit including a plurality of switching elements.

[0264] The control unit (12) can control the voltage output from the power source (11) by controlling the switching of the switching element of the power supply circuit. The power conversion circuit can convert the voltage output from the power source (11). For example, the power conversion circuit can include a buck converter that steps down the voltage output from the power source (11).

[0265] The control unit (12) can control the on / off operation of the switching element included in the power conversion circuit to adjust the level of the voltage output from the power conversion circuit. When the on state of the switching element continues, the level of the voltage output from the power conversion circuit may correspond to the level of the voltage output from the power source (11). The duty ratio for the on / off operation of the switching element may correspond to the ratio of the voltage output from the power conversion circuit to the voltage output from the power source (11). As the duty ratio for the on / off operation of the switching element decreases, the level of the voltage output from the power conversion circuit may decrease. The heater (18) can be heated based on the voltage output from the power conversion circuit.

[0266] The control unit (12) can control power to be supplied to the heater (18) using at least one of the pulse width modulation (PWM) method and the proportional-integral-differential (PID) method.

For example, the control unit (12) can compare the sensing value of the signal of the reuse detection sensor with a first reference range that includes a first color, and if the sensing value is included in the first reference range, it can determine that the stick (S) has not been used. For example, the control unit (12) can compare the sensing value of the signal of the reuse detection sensor with a second reference range that includes a second color, and if the sensing value is included in the second reference range, it can determine that the stick (S) has been used.
