Description

[Technical field]

[0001] The present invention relates to a vaporizer and an aerosol generating device including the same, and more particularly to a vaporizer that increases the amount of aerosol generated, and an aerosol generating device including the same. [Background technology]

[0002] Recently, there has been an increasing demand for an alternative method to overcome the shortcomings of conventional cigarettes. For example, instead of a method of generating aerosol by burning a cigarette, there is an increasing demand for a method of generating aerosol by heating an aerosol generating material. As a result, research into heated aerosol products or heated aerosol generating devices has been actively conducted.

[0003] The heated aerosol generating device may also include a vaporizer that heats an aerosol generating material in a liquid or gel state. Here, the vaporizer stores the aerosol generating material therein, transfers the stored aerosol generating material to a transfer element such as a wick, and heats the aerosol generating material via a heating element positioned adjacent to the transfer element to generate an aerosol. The generated aerosol may be discharged to the outside through a passage formed in the vaporizer and / or the aerosol generating device. Summary of the Invention [Problem to be solved by the invention]

[0004] In order for an aerosol generating device to produce a plentiful and uniform amount of aerosol, the aerosol generating material stored inside the vaporizer needs to be delivered abundantly and uniformly to a delivery element such as a wick.

[0005] For example, if the aerosol generating material within the vaporizer is not sufficiently transferred to the wick, the heating element will not have enough aerosol generating material to heat, resulting in insufficient aerosol production or uneven aerosol production.

[0006] The problems to be solved through the present embodiment are not limited to the problems mentioned above, and problems not mentioned will be clearly understood by a person having ordinary skill in the art to which the present embodiment pertains from this specification and the attached drawings. [Means for solving the problem]

[0007] The present embodiment provides a vaporizer having an improved structure for allowing the aerosol stored inside the vaporizer to be abundantly and uniformly delivered to the wick, and an aerosol generating device including the same.

[0008] In one embodiment, the vaporizer includes a storage section for storing an aerosol generating substance; a wick for absorbing the aerosol generating substance; a heating element for heating the aerosol generating substance absorbed in the wick; and a storage section for accommodating the wick, the storage section including at least one support groove for supporting at least a portion of the wick and at least one storage groove for temporarily storing the aerosol generating substance so as to transfer the aerosol generating substance to the wick, the maximum width of the storage groove being wider than the maximum width of the support groove.

[0009] In one embodiment, the aerosol generating device also includes a vaporizer and a processor that controls power supplied to the heating element included in the vaporizer. Effect of the Invention

[0010] The vaporizer according to the above-described embodiment can increase the amount of aerosol generated by increasing the amount of aerosol generating material stored in the storage unit that is transferred to the wick.

[0011] In addition, the vaporizer of the above-mentioned embodiment has a structure inside the vaporizer that can easily remove air bubbles that hinder the movement of the aerosol generating material, thereby making it possible to maintain a uniform amount of the aerosol generating material being transmitted.

[0012] The effects of this embodiment are not limited to the effects described above, and effects not mentioned will be clearly understood by a person having ordinary skill in the art to which this embodiment pertains from this specification and the accompanying drawings.

However, the present invention may be embodied in many different forms and is not limited to the preferred embodiments set forth herein.

[0040] FIG. 1 is a front view of an aerosol generating device to which a vaporizer according to one embodiment is coupled.

[0041] 1, a vaporizer 1 according to an embodiment can be coupled to a main body 2 to operate as an aerosol generating device 1000. For example, the vaporizer 1 can be coupled to a region of the main body 2. The coupling direction of the vaporizer 1 is not limited to the illustrated example, and the vaporizer 1 can be coupled to the main body 2 along the longitudinal direction of the aerosol generating device 1000.

[0042] In one embodiment, the aerosol generating device 1000 also includes a processor (not shown) and a battery (not shown). The battery and the processor may be electrically connected to the vaporizer 1. For example, the battery and the processor may supply power to and control the vaporizer 1. The aerosol generating device 1000 may thereby heat the aerosol generating material in a liquid or gel state stored in the vaporizer 1 to generate an aerosol.

[0043] In another embodiment, the aerosol generating device 1000 further includes a housing including a storage space (not shown) in which an aerosol product (e.g., a cigarette) is contained, and a separate heater (not shown) for heating the aerosol product contained in the housing.

[0044] For example, the receiving space and the heater may be located in the body 2. In one region of the body 2, the vaporizer 1 may be coupled, and in another region of the body 2, an aerosol product may be inserted.

[0045] The aerosol generating device 1000 can generate aerosol not only by using the vaporizer 1 but also by using an inserted aerosol product, thereby realizing a hybrid type aerosol generating device 1000.

[0046] In yet another embodiment, the aerosol generating device 1000 further includes a removable cap (not shown) for protecting at least a portion of the main body 2 and the vaporizer 1 coupled to the main body 2. The removable cap may be coupled to one end of the aerosol generating device 1000 where the vaporizer 1 and the main body 2 are coupled. For example, the detachable cap may be detached from the main body 2 for a user to replace the vaporizer 1.

[0047] 2A is an exploded perspective view of the evaporator shown in FIG. 1, and FIG. 2B is a bottom perspective view of the evaporator shown in FIG.

[0048] 2A and 2B, the vaporizer 1 according to one embodiment also includes a storage portion 10, a sealing portion 20, a wick 30, a heating element 40, a housing portion 50, and a cover 60. The storage portion 10, the sealing portion 20, the wick 30, the heating element 40, the housing portion 50, and the cover 60 may be coupled in the z-axis direction shown.

[0049] For example, after the heating element 40 and the wick 30 are accommodated in the accommodation part 50, the accommodation part 50 may be inserted inside the cover 60, and the sealing part 20 may be coupled with the accommodation part 50. Thus, the sealing part 20 and the accommodation part 50 may be located inside the cover 60. Finally, the storage part 10 and the cover 60 may be coupled to each other, and the vaporizer 1 may be assembled. However, the assembly sequence and coupling manner of the vaporizer 1 are not limited to the above example.

[0050] The storage unit 10 can store an aerosol-generating substance. The aerosol-generating substance may be in a liquid or gel state and may be stored in the storage unit 10. The aerosol-generating substance stored in the storage unit 10 may be transferred to the wick 30 and absorbed into the wick 30, and the aerosol-generating substance absorbed into the wick 30 may be heated by the heating element 40 to be converted into an aerosol.

[0051] At least a region of reservoir 10 may include an opening, for example, a bottom surface, or at least a portion of a bottom surface, of reservoir 10 such that the aerosol-generating material may naturally migrate out of reservoir 10 by gravity.

[0052] According to one embodiment, the storage portion 10 may be coupled to a seal 20 that prevents leakage of the aerosol generating material. The seal 20 may be coupled to at least one region of the storage portion 10 (e.g., an open side of the storage portion 10) such that the storage portion 10 and the seal 20 together form a storage space 12 for containing the aerosol generating material.

[0053] The sealing portion 20 may also be made of a material that allows for a tight connection between the storage portion 10 and the sealing portion 20. For example, the sealing portion 20 may also be made of an elastic material such as, but not limited to, rubber or silicone.

[0054] The sealing part 20 is tightly coupled to the storage part 10 to prevent leakage of the aerosol-generating material. That is, the sealing part 20 is tightly coupled to the storage part 10 so that no gap is generated between the sealing part 20 and the storage part 10.

[0055] The sealing part 20 is fabricated so as to be detachable from the storage part 10 or integrally with the storage part 10.

[0056] The sealing portion 20 also includes at least one opening 22 so that the aerosol-generating substance stored in the storage portion 10 can move to the outside of the storage portion 10 while the storage portion 10 and the sealing portion 20 are coupled.

[0057] For example, the storage unit 10 may include an open side exposing the storage space to the outside, and the sealing unit 20 including the opening 22 may be coupled to the open side of the storage unit 10. As a result, the aerosol-generating material stored in the storage space 12 of the storage unit 10 may move to the outside of the storage unit 10 through the opening 22 formed in the sealing unit 20, and the aerosol-generating material stored in the storage unit 10 may be prevented from leaking to the outside of the storage unit 10 through gaps other than the opening 22.

[0058] The wick 30 can receive the aerosol-generating substance from the storage unit 10 and absorb the aerosol-generating substance. The wick 30 can have an elongated shape. For example, the wick 30 can have a columnar shape that is elongated in one direction. Specifically, the wick 30 can have a polygonal prism shape such as a cylinder, a rectangular prism, or a triangular prism, but is not limited to the above examples. The wick 30 can also have a rod-like, needle-like, or flat shape.

[0059] A portion of the wick 30 can absorb the aerosol-generating substance supplied from the storage unit 10. For example, the aerosol-generating substance absorbed in one portion of the wick 30 can move to another portion of the wick 30 by capillary action. The wick 30 can include a variety of materials. For example, the wick 30 can include at least one of cotton, ceramic, and glass fiber.

[0060] In one embodiment, wick 30 also includes a first end 31, a second end 33, and a central portion 32 between first end 31 and second end 33. Aerosol generating substance provided from storage portion 10 may be absorbed into wick 30 via first end 31 and second end 33. Aerosol generating substance absorbed into wick 30 may be transferred to central portion 32 of wick 30.

[0061] The heating element 40 can heat the aerosol generating material absorbed in the wick 30 to generate an aerosol. The heating element 40 can be disposed adjacent to the wick 30. The heating element 40 can heat the liquid aerosol generating material transferred to the center portion 32 of the wick 30 to generate an aerosol.

[0062] For example, the heating element 40 may be a coiled resistive heater wound around the outer periphery of the central portion 32 of the wick 30. As another example, the heating element 40 may be a resistive heater printed on the central portion 32 of the wick 30. The heating element 40 is not limited to the above examples, and the heating element 40 may be a porous element formed integrally with the wick 30.

[0063] The housing 50 also includes housing spaces 51, 52, 53 for housing the wick 30 and the heating element 40. For example, the housing 50 also includes at least one support groove 52 for supporting at least a portion of the wick 30, at least one storage groove 51 for temporarily storing the aerosol generating substance for transfer to the wick 30, and a central space 53 for housing the central portion 32 of the wick 30.

[0064] At least a portion of the wick 30 may be located within the cavity and surrounded by the housing 50 and the seal 20. For example, the central portion 32 of the wick 30, around which the heating element 40 is wound, may be located within the cavity where the aerosol may be generated.

[0065] In addition, outside air flows into the interior of the storage unit 50 through the inlet 56 of the storage unit 50, and the aerosol generated in the cavity can be discharged to the outside of the storage unit 50 through the outlet 57 of the storage unit 50.

[0066] The receiving portion 50 and the supporting groove 52 and the storage groove 51 included in the receiving portion 50 will be described in detail with reference to other drawings.

[0067] The cover 60 may be combined with the accommodating part 50 and the sealing part 20. The cover 60 may also include an inner space 62 in which the accommodating part 50 and the sealing part 20 may be disposed. For example, the cover 60 may also include an inner space 62 having a shape corresponding to the outer shapes of the accommodating part 50 and the sealing part 20. The accommodating part 50 and the sealing part 20 may be correctly aligned with each other and disposed in the inner space 62 of the cover 60, and therefore the accommodating part 50 and the sealing part 20 may be protected from external impact.

[0068] The cover 60 also includes a connecting passage 64 that guides the aerosol discharged from the exhaust port 57 of the storage unit 50 to the outside of the vaporizer 1. For example, in a state in which the storage unit 50 is disposed in the inner space 62 of the cover 60, the connecting passage 64 can be located at a position corresponding to the exhaust port 57 so that the exhaust port 57 communicates with the connecting passage 64. The aerosol discharged to the outside of the storage unit 50 via the exhaust port 57 can move along the connecting passage 64 to the outside of the vaporizer 1.

[0069] For example, the connecting passage 64 may be connected to the main body 2 of the aerosol generation device 1000. The aerosol discharged to the outside of the storage part 50 through the outlet 57 may move to the main body 2 of the aerosol generation device 1000 through the connecting passage 64, and may be discharged to the outside of the aerosol generation device 1000 along an airflow passage formed in the main body 2.

[0070] The cover 60 also includes a connection terminal 66 that electrically connects the vaporizer 1 and the main body 2. For example, the connection terminal 66 can be connected to the heating element 40 and mediate the connection between the battery and the processor included in the main body 2 and the heating element 40. Thus, the heating element 40 can be powered and controlled by the battery and the processor.

[0071] FIG. 3A is a perspective view of a housing of a vaporizer according to one embodiment, FIG. 3B is a side view of the housing shown in FIG. 3A, and FIG. 3C is a plan view of the housing shown in FIG. 3A.

[0072] 3A to 3C, the container 50a of the vaporizer according to one embodiment includes a storage groove 51a, a support groove 52, a central space 53, an inlet 56, and an outlet 57. Here, the wick 30 and the heating element 40 may be positioned within the container spaces 51a, 52, and 53 of the container 50a.

[0073] As shown in the figure, the heating element 40 may be arranged to surround the outer peripheral surface of the wick 30 housed in the housing portion 50a, but the arrangement structure of the heating element 40 is not limited thereto.

[0074] For example, the heating element 40 may have a plate shape and be disposed adjacent to at least a portion of the wick 30 housed in the housing 50a so as to heat the wick 30. As another example, the heating element 40 may be a porous heater (e.g., a ceramic heater) integrally formed with the wick 30.

[0075] The support groove 52 may have a specified length l along a longitudinal direction (e.g., y-axis direction) of the core 30 so as to support at least a portion of the core 30, and a width W0 along a direction transverse to the longitudinal direction of the core 30 (e.g., x-axis direction) corresponding to a size (e.g., diameter d) of the core 30. The inner surface of the support groove 52 may thereby support the core 30 by contacting at least a portion of the outer circumferential surface of the core 30.

[0076] Storage groove 51a is also a space in which the aerosol-generating material supplied from the storage unit is temporarily stored or held. The aerosol-generating material that moves to the outside of the storage unit through an opening (e.g., opening 22 (FIG. 2A)) formed in the sealing unit (e.g., sealing unit 20 (FIG. 2A)) may first be transferred to storage groove 51a. The aerosol-generating material that is temporarily stored or held in storage groove 51a may be absorbed in a direction from one end 31, 33 of core 30 located in storage groove 51a toward center 32 of core 30.

[0077] In one embodiment, the housing 50a also includes a plurality of support grooves 52 formed to support the first end 31 and the second end 33 of the wick 30 housed in the housing 50a. The housing 50a also includes a storage groove 51a that temporarily stores the aerosol generating substance supplied from the storage portion and transmits the aerosol generating substance toward the first end 31 and the second end 33 of the wick 30 housed in the housing 50a.

[0078] For example, the support groove 52 may be located at a predetermined distance along the longitudinal direction of the core 30 from a central space 53 that forms part of the cavity of the receiving part 50a, and the storage groove 51a may be located at a position farther away from the central space 53 of the receiving part 50a than the support groove 52. That is, the storage groove 51a may be located at a position farther away from the central space 53 or cavity than the support groove 52.

[0079] The core 30 may contact the inner surface of the support groove 52. For example, the size d of the core 30 and the width W0 of the support groove 52 may fall within a fit tolerance range so that the core 30 may be inserted into the support groove 52.

[0080] The wick 30 accommodated in the accommodating portion 50a may extend from the central space 53 of the accommodating portion 50a to the end 52-1 of the support groove 52. The wick 30 accommodated in the accommodating portion 50a may also extend into the storage groove 51a via the end 52-1 of the support groove 52. At least a portion of the wick 30 accommodated in the accommodating portion 50a may contact at least a portion of the inner surface of the storage groove 51a. This increases the contact area of ​​the accommodated wick 30 with the aerosol-generating material held in the storage groove 51a, allowing it to absorb a larger amount of the aerosol-generating material.

[0081] When the heating element 40 is located in the center 32 of the wick 30, the aerosol-generating substance supplied to the wick 30 via both ends of the wick 30 must be transferred to the center 32 of the wick 30 before aerosol can be generated by the heating element 40. That is, in order to smoothly generate aerosol at the center 32 of the wick 30, it is important that the aerosol-generating substance be smoothly supplied to the wick 30 via both ends of the wick 30.

[0082] According to one embodiment, the maximum width W1 of the storage groove 51a is greater or greater than the maximum width W0 of the support groove 52. Here, the maximum width W1 may refer to the maximum width of the storage groove 51a in a distance measured transverse to the longitudinal direction of the core 30 (e.g., in the x-axis direction).

[0083] For example, the storage groove 51a may include a region extending from the first end 31 and the second end 33 of the core 30 in the longitudinal direction of the core 30, and a region extending from the first end 31 and the second end 33 of the core 30 in the width direction of the core 30 (i.e., transverse to the longitudinal direction of the core 30). In this case, the region extending in the width direction may extend from the first end 31 and the second end 33 of the core 30 in one or both directions along the width axis (i.e., the x-axis) of the core 30.

[0084] Because storage groove 51a has a wider maximum width than support groove 52, not only can storage groove 51a hold more aerosol-generating material supplied from the storage section, but the surface area of ​​core 30 that comes into contact with the aerosol-generating material held in storage groove 51a can be increased.

[0085] This allows the supply path of the aerosol generating substance to be expanded. The wick 30 can absorb the aerosol generating substance not only through the side surfaces of the first end 31 and the second end 33 but also through the circumferential surfaces of the first end 31 and the second end 33. As a result, the amount of aerosol generating substance absorbed by the wick 30 increases, and the amount of aerosol generated by the vaporizer can be increased.

[0086] FIG. 3D is a view illustrating a state in which the receiving portion shown in FIG. 3A contacts the sealing portion.

[0087] 3D, the sealing portion 20, which includes the opening 22 through which the aerosol-generating material travels, may contact or be coupled to the storage portion 50a. Here, the sealing portion 20 may be in contact with the storage portion 50a when coupled to the storage portion 10, but the storage portion 10 is omitted in the drawing to facilitate understanding.

[0088] In one embodiment, the opening 22 may be located at a position corresponding to the storage groove 51a when the storage portion and the receiving portion 50a are coupled together, so that the aerosol generating material stored in the storage portion moves to the storage groove 51a.

[0089] For example, the opening 22 may be positioned to form a transfer passage 25 connected to the storage groove 51a when the sealing portion 20 contacts the storage portion 50a, thereby reducing the amount of aerosol-generating material leaking out of the vaporizer from between the sealing portion 20 and / or the storage portion 10 and the storage portion 50a, and allowing the aerosol-generating material to be efficiently supplied to the storage groove 51a.

[0090] As described above, the container 50a also includes the inlet 56 through which outside air flows into the vaporizer. The outside air that flows into the inside of the vaporizer through the inlet 56 passes through a cavity (not shown) where an aerosol is generated, and is discharged to the outside of the vaporizer through the outlet 57 from which the aerosol is discharged, so that air circulation can occur inside the vaporizer.

[0091] When the aerosol-generating material stored in the storage portion 10 and / or the storage groove 51a is moved to the central space 53 via the wick 30, a pressure difference may be generated between the storage portion 10 and the central space 53 and / or in the storage groove 51a.

[0092] To compensate for the pressure difference, some of the outside air flowing into the cavity may flow back in a direction (e.g., +y or -y direction) opposite to the direction of movement (e.g., -y or +y direction) of the aerosol generating material moving from one end of the wick 30 to the center of the wick 30. As a result, some of the outside air may move to the storage groove 51a and / or the opening 22, and air bubbles may form in the storage groove 51a and / or the opening 22.

[0093] Air bubbles may form in opening 22 and / or storage groove 51a and narrow or close passage 25 for the aerosol-generating material supplied from the storage portion to storage groove 51a, thereby hindering uniform supply of the aerosol-generating material from the storage portion to storage groove 51a. Therefore, the internal structure of the vaporizer may be designed to prevent passage 25 for the aerosol-generating material from being blocked by air bubbles.

[0094] 3D, the size of the opening 22 may correspond to the size of the inlet side of the storage groove 51a through which the aerosol generating material is supplied. For example, the maximum width W1 of the storage groove 51a may be the same as or larger than the maximum width W2 of the opening 22. As another example, the ratio of the maximum width W1 of the storage groove 51a to the maximum width W2 of the opening 22 may be approximately 1:0.8 to 1:1.2.

[0095] In this way, the size of opening 22 corresponds to the size of the inlet side of storage groove 51a, so that movement path 25 through which the aerosol generating material moves is maximized and the phenomenon of the outlet becoming narrower due to the difference in size between opening 22 and storage groove 51a can be prevented. In addition, even if air bubbles are generated in storage groove 51a and / or opening 22, the air bubbles can be easily removed, so that the phenomenon of movement path 25 through which the aerosol generating material moves becoming clogged can be prevented.

[0096] In one embodiment, the sealing portion 20 further includes an extended surface 23 connected to the opening 22 and inclined toward the wick 30. The aerosol generating material may be in a liquid or gel state having high viscosity, which may slow down the passage through the narrow passage or may form a film in the narrow passage, causing the passage to become clogged. According to one embodiment, the aerosol generating material stored in the storage portion 10 may easily move to the outside of the storage portion 10 (e.g., the storage groove 51a) by entering the opening 22 along the extended surface 23 formed adjacent to the storage groove 51a.

[0097] 3D, the sealing portion 20 may contact the core 30 housed in the housing portion 50a. As a result, at least a portion of the core 30 may be surrounded by the sealing portion 20 and the housing portion 50a. For example, the periphery of both ends of the core 30 may contact the support groove 52 and a portion of the sealing portion 20, and both ends of the core 30 may be surrounded by the support groove 52 and the sealing portion 20.

[0098] In one embodiment, the sealing portion 20 also includes a support portion 24 that protrudes in a direction (e.g., in the -z direction) away from the storage portion (e.g., storage portion 10 (FIG. 2A)). The support portion 24 is formed at a position facing the support groove 52 when the sealing portion 20 abuts against the receiving portion 50a, and the support portion 24 can be inserted into the support groove 52.

[0099] Both ends of the core 30 located between the receiving portion 50a and the sealing portion 20 may contact the support groove 52 and the support portion 24. That is, the lower portion of the end of the core 30 may be surrounded by the support groove 52, and the upper portion may be surrounded by the support portion 24 inserted into the support groove 52.

[0100] This reduces the gap 35 between the outer peripheral surface of the core 30 and the support groove 52 and / or the support portion 24, and can reduce leakage of the aerosol-generating substance from the storage groove 51a into the central space 53.

[0101] As a result, most of the aerosol generating material held in the storage groove 51a may move to the center of the wick 30 via the end of the wick 30, reducing the amount of aerosol generating material leaking outside the vaporizer.

[0102] The position of the core 30 may be fixed by the sealing portion 20 and the receiving portion 50a. For example, the end of the core 30 located in the support groove 52 may be pressed by the support portion 24 and / or the support groove 52 to maintain the position of the core 30.

[0103] FIG. 4A is an oblique view of a container included in a vaporizer according to another embodiment, FIG. 4B is a side view of the container shown in FIG. 4A, and FIG. 4C is a plan view of the container shown in FIG. 4A.

[0104] 4A to 4C, the receiving portion 50b included in the vaporizer according to another embodiment also includes a storage groove 51b having a structure different from the storage groove 51a of the receiving portion 50a included in the vaporizer shown in FIGS. 3A to 3C.

[0105] 4C, the storage groove 51b also includes a first region 51b-1 and a second region 51b-2. The first region 51b-1 is also a region extending from the end 31 of the core 30 housed in the housing portion 50b in the longitudinal direction (e.g., y-axis direction) of the core 30. The second region 51b-2 is also a region extending from the end 31 of the core 30 in the width direction (e.g., x-axis direction) of the core 30. The second region 51b-2 extending in the width direction of the storage groove 51b may extend from the end 31 of the core 30 in both directions (e.g., +x and -x directions) transverse to the longitudinal direction of the core 30.

[0106] For example, the cross section of the storage groove 51b formed along a cutting plane (xy plane) of the core 30 (i.e., a cross section cut along the width direction of the core 30 transverse to the longitudinal direction of the core 30) is generally rectangular or trapezoidal. In such a cross section, the width W1 of the second region 51b-2 of the storage groove 51b is wider than the width W1' of the cross section of the first region 51b-1 of the storage groove 51b.

[0107] The width W1' of the first region 51b-1 of the storage groove 51b and the width W0 of the support groove 52 are not related to each other.

[0108] The aerosol-generating substance held in the first region 51b-1 of the storage groove 51b can be efficiently absorbed into the interior of the wick 30 via the side surface of the end 31 of the wick 30. The aerosol-generating substance held in the second region 51b-2 of the storage groove 51b can be efficiently absorbed into the interior of the wick 30 via the outer circumferential surface of the end 31 of the wick 30.

[0109] In this manner, the amount of aerosol generating material that can be held by storage groove 51b may be increased because the space of storage groove 51b includes an area that is expanded in the longitudinal and transverse directions of wick 30. Also, the delivery path through which the aerosol generating material can be absorbed into wick 30 may be expanded.

[0110] FIG. 5A is an oblique view of a container of a vaporizer according to yet another embodiment, FIG. 5B is a side view of the container shown in FIG. 5A, and FIG. 5C is a plan view of the container shown in FIG. 5A.

[0111] 5A to 5C, the accommodating portion 50c of the evaporator according to another embodiment also includes a storage groove 51c having a structure different from the storage grooves 51a and 51b of the accommodating portions 50a and 50b included in the evaporator shown in FIGS. 3A to 4C.

[0112] 5A to 5C, the storage groove 51c may include a first region extending from the end 31 of the core 30 in a longitudinal direction (e.g., y-axis direction) of the core 30, and a second region extending from the end 31 of the core 30 in a width direction (e.g., x-axis direction). Here, the second region extending in the width direction of the core 30 may extend from the end 31 of the core 30 in one side direction (e.g., +x direction).

[0113] For example, referring to FIG. 5B, when viewed from a cross section formed along a cutting plane (e.g., an xz plane) of the storage groove 51c, the storage groove 51c also includes a bottom surface 51c-1, a first side wall surface 51c-2 and a second side wall surface 51c-3.

[0114] The bottom surface 51c-1 and the first side wall surface 51c-2 may be in contact with at least a portion of the core 30. The second side wall surface 51c-3 may be spaced apart from the first side wall surface 51c-2 and the core 30 in the width direction of the core 30 (i.e., the x-axis direction). Here, the maximum width W1″ of the storage groove 51c, which is the maximum distance between the first side wall surface 51c-2 and the second side wall surface 51c-3, is wider than the maximum width W0 of the support groove 52.

[0115] The structure of the storage groove 51c is designed taking into consideration a compromise between the amount of aerosol generating material to be stored or retained and the leakage or spillage of the aerosol generating material that occurs in the vaporizer.

[0116] 5A to 5C, the internal space of the storage groove 51c is expanded so that a sufficient amount of aerosol generating material can be supplied to the wick 30. That is, the storage groove 51c is extended in only one width direction (e.g., the +x direction), and the supply path of the aerosol generating material is expanded to a certain limit while leakage of the aerosol generating material can be reduced.

[0117] FIG. 6A is an oblique view of a container included in a vaporizer according to yet another embodiment, FIG. 6B is a side view of the container shown in FIG. 6A, and FIG. 6C is a plan view of the container shown in FIG. 6A.

[0118] 6A to 6C, the receiving portion 50d included in the vaporizer according to another embodiment also includes a storage groove 51d having a structure different from the storage grooves 51a, 51b, and 51c of the receiving portions 50a, 50b, and 50c included in the vaporizers shown in FIGS. 3A to 5C.

[0119] According to yet another embodiment, the width of the storage groove 51d may be reduced in a direction away from the storage portion (e.g., in the -z direction), i.e., the storage groove 51d may have a wide entrance through which the aerosol generating material is supplied and may have a tapered shape that narrows toward the depth of the storage groove 51d (e.g., in the -z direction).

[0120] For example, referring to FIG. 6B, when viewed from a cross section of the preservation groove 51d formed by a cutting plane (eg, xz plane), the preservation groove 51d also includes a curved surface 51d-1 and an inclined surface 51d-2.

[0121] The curved surface 51d-1 is also a surface formed along the circumferential direction of the core 30 and in contact with the core 30. The inclined surface 51d-2 is also a surface formed toward the depth direction of the storage groove 51d so that the storage groove 51d becomes narrower. Here, the angle of the inclined surface 51d-2 may be designed differently depending on the embodiment, and the spatial volume inside the storage groove 51d may be changed depending on the angle of the inclined surface 51d-2.

[0122] By having storage groove 51d have a width that decreases in a direction away from the storage portion, the likelihood of leakage or spillage of the aerosol generating material may be reduced.

[0123] Furthermore, the curved surface 51d-1 and / or the inclined surface 51d-2 of the storage groove 51d surrounds at least a portion of the wick 30, and the aerosol-generating substance supplied from the storage section can be guided along the supply path formed by the inclined surface 51d-2 to the wick 30. According to the above-described embodiment, the formation of dead space in which the aerosol-generating substance may accumulate can be minimized in the storage groove 51d.

[0124] The structures of the core 30, the heating element 40, and the receiving portions 50a, 50b, 50c, and 50d having the support groove 52 and the storage grooves 51a, 51b, 51c, and 51d shown in Figures 3A to 6C are exemplary and may be modified into various forms different from those described above.

[0125] For example, the heating element 40 may not be wound around the core 30 but may be disposed adjacent to the core 30. The core 30 may have a mesh or plate shape instead of an elongated shape. In addition, the positions and numbers of the storage grooves 51a, 52b, 52c, 52d, the support grooves 52, the inlet 56, and the outlet 57 included in the receiving portions 50a, 50b, 50c, 50d may be changed.

[0126] FIG. 7 is a diagram illustrating an example of an aerosol product being inserted into an aerosol generation device according to one embodiment, and FIG. 8 is a diagram illustrating an example of an aerosol product being inserted into an aerosol generation device according to another embodiment.

[0127] 7 and 8, the aerosol generating apparatus 100 includes a battery 110, a control unit 120, a heater 130, and a vaporizer 140. An aerosol product 200 may be inserted into the internal space of the aerosol generating apparatus 100. For example, the aerosol generating apparatus 100 in FIG. 8 may be the same as the aerosol generating apparatus 1000 in FIG. 1, and the vaporizer 140 applied to the aerosol generating apparatus 100 in FIG. 7 and FIG. 8 may be the same as the vaporizer 1 in FIG. 2A.

[0128] 7 and 8 includes a vaporizer, the present embodiment is not limited by the embodiment of the aerosol generating device, and the vaporizer may be omitted in the aerosol generating device 100. When the vaporizer is omitted in the aerosol generating device 100, the aerosol product 200 may generate an aerosol when the aerosol product 200 is heated by the heater 130 since the aerosol product 200 includes an aerosol generating material.

[0129] The aerosol generating device 100 shown in Figures 7 and 8 illustrates components related to this embodiment. Therefore, a person having ordinary skill in the art related to this embodiment can understand that the aerosol generating device 100 further includes other general components in addition to the components illustrated in Figures 7 and 8.

[0130] In addition, although the aerosol generating device 100 is illustrated in FIGS. 7 and 8 as including the heater 130, the heater 130 may be omitted if necessary.

[0131] In Fig. 7, the battery 110, the control unit 120, the vaporizer 140, and the heater 130 are illustrated as being arranged in a line. Also, in Fig. 8, the vaporizer 140 and the heater 130 are illustrated as being arranged in parallel. However, the internal structure of the aerosol generating device 100 is not limited to that illustrated in Fig. 7 or Fig. 8. In other words, the arrangement of the battery 110, the control unit 120, the vaporizer 140, and the heater 130 may be changed depending on the design of the aerosol generating device 100.

[0132] When the aerosol production product 200 is inserted into the aerosol generating device 100, the aerosol generating device 100 can activate the vaporizer 140 to generate an aerosol from the vaporizer 140. The aerosol generated by the vaporizer 140 passes through the aerosol production product 200 and is delivered to a user. The vaporizer 140 will be described in more detail below.

[0133] The battery 110 supplies power used for operating the aerosol generating device 100. For example, the battery 110 can supply power to heat the heater 130 or the vaporizer 140, and can supply power necessary for the control unit 120 to operate. The battery 110 can also supply power necessary for the display, sensor, motor, and the like provided in the aerosol generating device 100 to operate.

[0134] The control unit 120 generally controls the operation of the aerosol generation device 100. Specifically, the control unit 120 controls the operation of not only the battery 110, the heater 130, and the vaporizer 140, but also other components included in the aerosol generation device 100. The control unit 120 can also check the state of each component of the aerosol generation device 100 and determine whether the aerosol generation device 100 is in a state where it can operate freely.

[0135] The control unit 120 includes at least one processor. The processor may be realized by an array of a number of logic gates, or may be realized by a combination of a general-purpose microprocessor and a memory storing a program that can be executed by the microprocessor. Those skilled in the art will understand that the controller 120 may also be realized by other types of hardware.

[0136] The heater 130 may be heated by power supplied from the battery 110. For example, when the aerosol production article 200 is inserted into the aerosol generating device 100, the heater 130 may be located outside the aerosol production article 200. Thus, the heated heater 130 may increase the temperature of the aerosol generating material within the aerosol production article 200.

[0137] The heater 130 may be an electrically resistive heater. For example, the heater 130 may include an electrically conductive track, and the heater 130 may be heated by passing an electric current through the electrically conductive track. However, the heater 130 is not limited to the above example, and may be any heater that can be heated to a desired temperature. Here, the desired temperature may be preset in the aerosol generating device 100, or may be set by a user to a desired temperature.

[0138] As another example, the heater 130 may be an induction heater, specifically, the heater 130 may include an electrically conductive coil for inductively heating the aerosol product, and the aerosol product may include a susceptor that may be heated by the induction heater.

[0139] 7 and 8, the heater 130 is illustrated as being disposed externally of the aerosol product 200, but is not limited thereto. For example, the heater 130 may include a tube-type heating element, a plate-type heating element, a needle-type heating element, or a rod-type heating element, and depending on the shape of the heating element, the inside or outside of the aerosol product 200 may be heated.

[0140] In addition, a plurality of heaters 130 may be disposed in the aerosol generating device 100. In this case, the plurality of heaters 130 may be disposed so as to be inserted inside the aerosol product 200, and also disposed outside the aerosol product 200. In addition, some of the plurality of heaters 130 may be disposed so as to be inserted inside the aerosol product 200, and the rest may be disposed outside the aerosol product 200. In addition, the shape of the heater 130 is not limited to the shapes illustrated in Figs. 7 and 8, and may be manufactured in various shapes.

[0141] The vaporizer 140 can heat the liquid composition and generate an aerosol, which can pass through the aerosol product article 200 and be delivered to a user. In other words, the aerosol generated by the vaporizer 140 can travel along an airflow passage of the aerosol generating device 100, which airflow passage can be configured to allow the aerosol generated by the vaporizer 140 to pass through the aerosol product article 200 and be delivered to a user.

[0142] For example, the vaporizer 140 may include, but is not limited to, a liquid storage unit, a liquid transfer means, and a heating element. For example, the liquid storage unit, the liquid transfer means, and the heating element may be included in the aerosol generating device 100 as independent modules. Here, the liquid storage unit, the liquid transfer means, and the heating element may be the same as the storage unit 10, the wick 30, and the heating element 40 included in the vaporizer 1 described in FIG. 2A.

[0143] The liquid storage unit can store a liquid composition, for example, a liquid containing a tobacco-containing substance including a volatile tobacco flavor component, or a liquid containing a non-tobacco substance. The liquid storage unit can be made to be detachable / attachable to / from the vaporizer 140, or can be made integral with the vaporizer 140.

[0144] For example, the liquid composition may include water, solvent, ethanol, plant extract, fragrance, flavoring agent, or vitamin mixture. The fragrance may include, but is not limited to, menthol, peppermint, spearmint oil, various fruit flavoring ingredients, etc. The flavoring agent may include ingredients that can provide a variety of flavors or tastes to the user. The vitamin mixture may include, but is not limited to, at least one of vitamin A, vitamin B, vitamin C, and vitamin E. The liquid composition may also include an aerosol forming agent, such as glycerin and propylene glycol.

[0145] The liquid transfer means can transfer the liquid composition of the liquid reservoir to the heating element, for example, but not limited to, a wick such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

[0146] The heating element is an element for heating the liquid composition transferred by the liquid transfer means. For example, the heating element can be, but is not limited to, a metal hot wire, a metal hot plate, a ceramic heater, etc. Also, the heating element can be configured with a conductive filament such as a nichrome wire and arranged in a structure wound around the liquid transfer means. The heating element can be heated by supplying an electric current and transfer heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, an aerosol can be generated.

[0147] For example, the vaporizer 140 may also be referred to as, but is not limited to, a cartomizer or an atomizer.

[0148] The aerosol generation device 100 may further include a general-purpose configuration in addition to the battery 110, the control unit 120, the heater 130, and the vaporizer 140. For example, the aerosol generation device 100 may include a display capable of outputting visual information, and / or a motor for outputting tactile information. The aerosol generation device 100 may also include at least one sensor (such as a puff sensor, a temperature sensor, or an aerosol product insertion sensor). The aerosol generation device 100 may also be fabricated in a structure that allows external air to flow in or internal gas to flow out even when the aerosol product 200 is inserted.

[0149] 7 and 8, the aerosol generating device 100 may form a system together with a separate cradle. For example, the cradle may be used to charge the battery 110 of the aerosol generating device 100. Alternatively, the heater 130 may be heated when the cradle and the aerosol generating device 100 are coupled together.

[0150] The aerosol producing article 200 may be similar to a typical combustible cigarette. For example, the aerosol producing article 200 may be divided into a first portion including an aerosol generating material and a second portion including a filter or the like. Alternatively, the second portion of the aerosol producing article 200 may also include an aerosol generating material. For example, the aerosol generating material in the form of granules or capsules may be inserted into the second portion.

[0151] The entire first part may be inserted into the aerosol generating device 100, and the second part may be exposed to the outside. Alternatively, only a part of the first part may be inserted into the aerosol generating device 100, or both the first part and the second part may be inserted. A user may inhale aerosol while holding the second part in his / her mouth. In this case, the aerosol is generated by external air passing through the first part, and the generated aerosol passes through the second part and is delivered to the user's mouth.

[0152] As an example, the outside air may be introduced through at least one air passage formed in the aerosol generating device 100. For example, the opening and closing of the air passage formed in the aerosol generating device 100 and / or the size of the air passage may be adjusted by a user. As a result, the amount of atomization, smoking sensation, etc. may be adjusted by the user. As another example, the outside air may be introduced into the aerosol product 200 through at least one hole formed in the surface of the aerosol product 200.

[0153] An example aerosol product 200 will now be described with reference to FIG.

[0154] FIG. 9 is a diagram illustrating an example of an aerosol product.

[0155] 9, the aerosol product 200 includes a tobacco rod 210 and a filter rod 220. The first portion described with reference to FIGS.

[0156] 9, the filter rod 220 is illustrated as a single segment, but is not limited thereto. In other words, the filter rod 220 may be composed of multiple segments. For example, the filter rod 220 may include a first segment for cooling the aerosol and a second segment for filtering a predetermined component contained in the aerosol. If necessary, the filter rod 220 may further include at least one segment for performing another function.

[0157] The aerosol product 200 may be wrapped by at least one wrapper 240. The wrapper 240 may have at least one hole through which external air can flow in or internal gas can flow out. As an example, the aerosol product 200 may be wrapped by one wrapper 240. As another example, the aerosol product 200 may be wrapped by two or more wrappers 240 in a superimposed manner. For example, the tobacco rod 210 may be wrapped by a first wrapper 241, and the filter rod 220 may be wrapped by wrappers 242, 243, and 244. Then, the entire aerosol product 200 may be further wrapped by a single wrapper 245. If the filter rod 220 is composed of multiple segments, each segment may be wrapped by a wrapper 242, 243, and 244.

[0158] The tobacco rod 210 includes an aerosol-generating material, such as, but not limited to, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. The tobacco rod 210 also includes other additives, such as flavoring agents, humectants, and / or organic acids. Flavoring liquid, such as menthol or a humectant, may also be added to the tobacco rod 210 by spraying it onto the tobacco rod 210.

[0159] The tobacco rod 210 may be manufactured in various ways. For example, the tobacco rod 210 may be manufactured from a sheet or a strand. The tobacco rod 210 may also be manufactured from cut tobacco, which is a tobacco sheet that has been finely shredded. The tobacco rod 210 may also be surrounded by a thermally conductive material. For example, the thermally conductive material may be a metal foil such as aluminum foil, but is not limited thereto. For example, the thermally conductive material surrounding the tobacco rod 210 may evenly distribute the heat transferred to the tobacco rod 210 and improve the thermal conductivity applied to the tobacco rod, thereby improving the tobacco taste. The thermally conductive material surrounding the tobacco rod 210 may also function as a susceptor that is heated by an induction heater. In this case, although not shown in the drawings, the tobacco rod 210 may further include an additional susceptor in addition to the thermally conductive material surrounding the outside.

[0160] The filter rod 220 is also a cellulose acetate filter. The shape of the filter rod 220 is not limited. For example, the filter rod 220 may be a cylindrical type rod or a tube type rod having a hollow inside. The filter rod 220 may also be a recess type rod. If the filter rod 220 is composed of multiple segments, at least one of the multiple segments may be manufactured in a different shape.

[0161] The filter rod 220 may be prepared to produce a flavor. For example, a flavoring liquid may be sprayed onto the filter rod 220, or a separate fiber coated with the flavoring liquid may be inserted into the filter rod 220.

[0162] The filter rod 220 also includes at least one capsule 230. Here, the capsule 230 can generate flavor or aerosol. For example, the capsule 230 is a structure in which a liquid containing a flavoring is covered with a coating. The capsule 230 can have a spherical or cylindrical shape, but is not limited thereto.

[0163] If the filter rod 220 includes a segment for cooling the aerosol, the cooling segment can be made of a polymeric material or a biodegradable polymeric material. For example, the cooling segment can be made of pure polylactic acid, but is not limited thereto. Alternatively, the cooling segment can be made of a cellulose acetate filter with multiple holes. However, the cooling segment is not limited to the above examples, and can be applicable without limitation as long as it can perform the function of cooling the aerosol.

[0164] An embodiment may also be embodied in the form of a recording medium including computer executable instructions such as a program module executed by a computer. A computer readable medium is any available medium that can be accessed by a computer, including both volatile and non-volatile media, and both separate and non-separate media. A computer readable medium also includes both a computer recording medium and a communication medium. The computer recording medium includes both volatile and non-volatile, separate and non-separate media embodied in any method or technology for storing information such as computer readable instructions, data structures, program modules, or other data. The communication medium typically includes computer readable instructions, data structures, other data in a modulated data signal such as a program module, or other transmission mechanism, and includes any information delivery medium.

[0165] It will be understood by those skilled in the art that the present invention may be embodied in various modified forms without departing from the essential characteristics described above. Therefore, the disclosed method should be considered from an illustrative rather than a restrictive perspective. The scope of the present invention is defined by the claims, not the above description, and all differences within the scope of the claims should be interpreted as being included in the present invention.
