Mode for Carrying Out the Invention

[0010] In the present embodiment, the terms used are, as much as possible, general terms that are currently widely used while considering the functions in the present embodiment. However, that also varies depending on the intentions of those skilled in the art, precedents, or the emergence of new technologies. Also, in specific cases, there are terms arbitrarily selected by the applicant, and in that case, the meaning thereof is described in detail in the description part of the invention. Therefore, the terms used in the present embodiment must be defined based not only on the name of the term but also on the meaning the term has and the overall content of the present embodiment.

[0011] Throughout the specification, when a certain part states that a certain component "includes", unless there is a specifically contrary description, it does not exclude other components and also means that it further includes other components. Also, terms such as "~ part" and "~ module" described in the specification mean a unit that processes at least one function or operation, and that can be embodied by hardware or software, or also by a combination of hardware and software.

[0012] As used in this specification, when an expression such as "at least any one" is before the arranged components, it modifies the entire components, not each of the arranged components. For example, the expression "at least any one of a, b, and c" must be interpreted to include a, b, c, a and b, a and c, b and c, or a, b, and c.

[0013] In one embodiment, the aerosol generating device is also a device that electrically heats a cigarette housed in an internal space to generate an aerosol.

[0014] The aerosol generating device also includes a heater. In one embodiment, the heater is also an electric resistance heater. For example, the heater also includes a conductive track, and when an electric current flows through the conductive track, the heater can be heated.

[0015] The heater also includes a tubular heating element, a plate-shaped heating element, a needle-shaped heating element, or a rod-shaped heating element, and depending on the form of the heating element, the inside or outside of the cigarette can be heated.

[0016] The cigarette also includes a tobacco rod and a filter rod. The tobacco rod can also be made of a sheet, a strand, or shredded tobacco with a finely cut tobacco sheet. Also, the tobacco rod can also be surrounded by a heat-conducting material. For example, the heat-conducting material can be a metal foil such as aluminum foil, but is not limited thereto.

[0017] The filter rod is also a cellulose acetate filter. The filter rod can be composed of at least one or more segments. For example, the filter rod can also include a first segment that cools the aerosol and a second segment that filters a predetermined component contained in the aerosol.

[0018] In other embodiments, the aerosol generating device is also a device that uses a cartridge holding an aerosol generating substance to generate an aerosol.

[0019] The aerosol generating device also includes a cartridge holding an aerosol generating substance and a main body supporting the cartridge. The cartridge can be detachably coupled to the main body, but is not limited thereto. The cartridge may be integrally formed with the main body, or assembled and fixed so as not to be detached by the user. The cartridge can be mounted on the main body with the aerosol generating substance accommodated therein. However, without being limited thereto, the aerosol generating substance may also be injected into the cartridge while the cartridge is coupled to the main body.

[0020] The cartridge can hold an aerosol generating substance having any one of various states such as a liquid state, a solid state, a gaseous state, and a gel state. The aerosol generating substance also includes a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing substance including a volatile tobacco flavor component, or a liquid containing a non-tobacco substance.

[0021] The cartridge can perform a function of converting the phase of the aerosol generating substance inside the cartridge into a gas phase and generating an aerosol by being operated by an electrical signal or a wireless signal transmitted from the main body. The aerosol can mean a vaporized particle generated from the aerosol generating substance and a gas in a state where air is mixed.

[0022] In yet another embodiment, the aerosol generating device can heat a liquid composition to generate an aerosol, and the generated aerosol can pass through a cigarette and be transmitted to the user. That is, the aerosol generated from the liquid composition can move along the air flow path of the aerosol generating device, and the air flow path can be configured such that the aerosol passes through a cigarette and is transmitted to the user.

[0023] The aerosol generating device may further include a core that absorbs the aerosol generating substance.

[0024] In still other embodiments, the aerosol generating device is also a device that generates an aerosol by heating an aerosol generating article accommodated in the aerosol generating device by an induction heating method.

[0025] The aerosol generating device also includes a susceptor and a coil. In one embodiment, the coil can apply a magnetic field to the susceptor. When power is supplied from the aerosol generating device to the coil, a magnetic field can be formed inside the coil. In one embodiment, the susceptor is also a magnetic body that generates heat by an external magnetic field. When the susceptor is located inside the coil and a magnetic field is applied to generate heat, the aerosol generating article can be heated. Also, optionally, the susceptor can be located inside the aerosol generating article.

[0026] In still other embodiments, the aerosol generating device further includes a cradle.

[0027] The aerosol generating device can form a system together with a separate cradle. For example, the cradle can charge the battery of the aerosol generating device. Or, the heater can be heated in a state where the cradle and the aerosol generating device are coupled.

[0028] Hereinafter, with reference to the accompanying drawings, embodiments of the present disclosure will be described in detail so that those having ordinary knowledge in the technical field can easily implement them. The present disclosure is implemented in a form that can be embodied in the aerosol generating devices of the various embodiments described above, or is implemented in various different forms, but is not limited to the embodiments described here.

[0029] Some of the components in the drawings are also illustrated with some exaggeration in their size, ratio, etc. Also, components illustrated on one drawing may not be illustrated on other drawings.

[0030] Also, throughout the specification, the "longitudinal direction" of a component is also the direction in which the component extends along a one-direction axis of the component. At this time, the one-direction axis of the component may mean the direction in which the component extends longer than other direction axes crossing the one-direction axis. For example, the longitudinal direction of the core is the direction in which the core illustrated in FIG. 4 extends, that is, the length l of the core w may mean the direction parallel to the direction.

[0031] Throughout the specification, "embodiment" is any section for easily explaining the invention in the present disclosure, and each embodiment does not necessarily have to be mutually exclusive. For example, the configuration disclosed in one embodiment can be applied and / or embodied in other embodiments, and can be changed, applied and / or embodied within the scope not departing from the present disclosure.

[0032] Also, the terms used in the present disclosure are for explaining the present embodiment and do not limit the present embodiment. In the present disclosure, the singular form includes the plural form unless otherwise specifically mentioned.

[0033] Hereinafter, with reference to the drawings, the present embodiment will be described in detail.

[0034] FIG. 1A is a front view of an aerosol generating device to which a vaporizer according to one embodiment is coupled.

[0035] According to FIG. 1A, the aerosol generating device 1000 also includes a vaporizer 1 and a main body 2. The vaporizer 1 can be coupled to a region of the main body 2. The coupling between the vaporizer 1 and the main body 2 is not limited to the example illustrated in FIG. 1A. For example, the vaporizer 1 can be coupled to the main body 2 on the side surface of the aerosol generating device 1000, and can also be coupled to the main body 2 on the upper surface or the lower surface along the longitudinal direction of the aerosol generating device 1000.

[0036] In other embodiments, the aerosol generating device 1000 further includes a housing (not shown) that includes a space for accommodating the aerosol generating article, and a separate heater (not shown) that heats the aerosol generating article housed in the housing. Thereby, the aerosol generating device 1000 can use the vaporizer 1 to generate an aerosol, and can also heat the aerosol generating article housed in the housing via the heater to generate an aerosol.

[0037] The aforementioned space for accommodating the aerosol generating article and the heater are also included in the main body 2. Thereby, the vaporizer 1 can be coupled to one region of the main body 2, and the aerosol generating article can be accommodated in another region of the main body 2.

[0038] In yet another embodiment, the aerosol generating device 1000 further includes a detachable cap (not shown). The cap can protect at least a part of the vaporizer 1 and the main body 2. The cap also protects the coupling portion between the vaporizer 1 and the main body 2. For example, when separating the main body 2 and the vaporizer 1 to replace the vaporizer 1, the cap is first separated, and then the vaporizer 1 is separated. Further, the cap also includes a hole communicating with the housing that includes the space for accommodating the aerosol generating article.

[0039] In one embodiment, the aerosol generating device 1000 includes a battery (not shown) that supplies power to the vaporizer 1, and a control unit (not shown) that controls the power supplied from the battery to the vaporizer 1. The battery and the control unit can be electrically connected to the vaporizer 1. Through the power supplied via the battery and the control unit, the vaporizer 1 can heat the aerosol generating substance to generate an aerosol.

[0040] Figure 1B is a perspective view of the aerosol generating device according to Figure 1A.

[0041] The aerosol generating device 1000 also includes a vaporizer 1 and a main body 2. The vaporizer 1 also includes a storage unit 110 for storing the aerosol generating substance and a heating chamber 120 for heating the aerosol generating substance. The vaporizer 1 including the storage unit 110 and the heating chamber 120 can be coupled to the main body 2 of the aerosol generating device 1000.

[0042] FIG. 2A is an exploded perspective view of a heating chamber according to an embodiment.

[0043] Referring to FIG. 2A, the heating chamber 120 according to an embodiment also includes a wick 121, a coil 122, and a housing portion 123.

[0044] The wick 121 extends in the longitudinal direction and also absorbs the aerosol generating substance. The aerosol generating substance can be transmitted from the storage unit 110 and absorbed by the wick 121. The wick 121 is also elongated and extends in the longitudinal direction. For example, it can have various columnar shapes such as cylindrical, triangular prism-shaped, and quadrangular prism-shaped, but is not limited thereto.

[0045] The aerosol generating substance supplied from the storage unit 110 is absorbed by a part of the wick 121 and can move to other parts of the wick 121 by capillary action. In one embodiment, the aerosol generating substance supplied from the storage unit 110 can be absorbed by one end in the longitudinal direction of the wick 121 and move to the central part, but is not limited to such a transmission method. The aerosol generating substance stored in the storage unit 110 is also in a liquid or gel state.

[0046] The wick 121 is also formed of silica. The wick 121 is formed of silica and can prevent the transmission of burnt smell and harmful substances to the user by minimizing carbonization during heating.

[0047] The coil 122 is wound around the core 121 and can heat the aerosol product substance absorbed by the core 121 to generate an aerosol. For example, the coil 122 is wound around the central portion in the longitudinal direction of the core 121, absorbs at one end portion in the longitudinal direction of the core 121, and the coil 122 can heat the aerosol product substance that has moved to the central portion to generate an aerosol.

[0048] The coil 122 is also a resistive heater wound around the core 121. The coil 122 is in a form wound around the core 121, and the method and order of assembling the core 121 and the coil 122 are not limited. For example, the coil 122 may be wound around the outer peripheral surface of the core 121, or the core 121 may be fitted into the wound coil 122.

[0049] The housing portion 123 can house the core 121. Specifically, it can house the core 121 around which the coil 122 is wound. The housing portion 123 may have a housing groove 123b for housing the core 121.

[0050] In addition, the housing portion 123 also includes an inlet 123a for allowing outside air to flow into the inside of the housing portion 123, and also includes an outlet 123c for discharging the generated aerosol to the outside of the housing portion 123. The housing portion 123 can form the appearance of the heating chamber 120, and the outlet 123c is also in a shape that can be connected to the main body 2. Needless to say, the shapes, positions, numbers, etc. of the inlet 123a and the outlet 123c can be changed into various forms.

[0051] The housing portion 123 also includes a terminal (not shown) for electrically connecting the vaporizer 1 and the main body 2. Through this, the vaporizer 1 can be connected to the battery and the control unit.

[0052] FIG. 2B is an exploded perspective view of a vaporizer according to an embodiment.

[0053] Referring to FIG. 2B, the vaporizer 1 also includes a storage part 110 and a heating chamber 120. The heating chamber 120 further includes the aforementioned wick 121, coil 122, housing part 123, a sealing part 124 and a connecting part 125.

[0054] The wick 121, coil 122, housing part 123, sealing part 124 and connecting part 125 can be coupled in the illustrated z-axis direction. For example, after the wick 121 and the coil 122 are accommodated in the housing part 123, the sealing part 124 can be coupled to the housing part 123. Also, the housing part 123 can be inserted into the inner space 125a of the connecting part 125.

[0055] The storage part 110 and the heating chamber 120 are coupled, and the vaporizer 1 is assembled. Specifically, the storage part 110 and the connecting part 125 of the heating chamber 120 are coupled, and the vaporizer 1 can be assembled. However, the assembly order and coupling method of the vaporizer 1 are not limited to the aforementioned example.

[0056] The sealing part 124 can prevent the aerosol product substance stored in the storage part 110 from leaking out. The sealing part 124 can be closely adhered and coupled to a part of the storage part 110. That is, it can mean that the sealing part 124 can be firmly coupled to the storage part 110 so that there is no gap for the aerosol product substance to leak out between the storage part 110 and other components (e.g., the housing part).

[0057] For example, the storage part 110 can also have a groove that can be firmly coupled to the sealing part 124. Also, the sealing part 124 can include an elastic material such as rubber or silicon so as to be firmly coupled to the storage part 110, but is not limited thereto.

[0058] The sealing part 124 also includes at least one opening 124b so that the aerosol product substance stored in the storage part 110 can move to the accommodation part 123. Thereby, the sealing part 124 moves the aerosol product substance stored in the storage part 110 to the outside of the storage part 110 through the opening 124b formed in the sealing part 124, and at the same time, the aerosol product substance stored in the storage part 110 can be prevented from leaking to the outside of the storage part 110 through gaps other than the opening 124b.

[0059] The sealing part 124 may have an inflow passage 124a communicating with the inflow port 123a of the accommodation part 123. The inflow passage 124a of the sealing part 124 is also a passage for introducing outside air and transmitting it to the inside of the accommodation part 123 through the inflow port 123a.

[0060] The connecting part 125 can accommodate the accommodation part 123 in the inner space 125a. The connecting part 125 can also accommodate the accommodation part 123 and the sealing part 124 in the inner space 125a. For example, the inner space 125a of the connecting part 125 may have an internal shape corresponding to the outer shapes of the accommodation part 123 and the sealing part 124. The connecting part 125 can properly align the accommodation part 123 and the sealing part 124 and protect the inside of the heating chamber 120.

[0061] When the heating chamber 120 further includes the connecting part 125, the connecting part 125 can form the appearance of the heating chamber 120. The connecting part 125 has a shape that can be connected to the main body 2 and may have a connecting passage 125b communicating with the discharge port 123c of the accommodation part 123.

[0062] The aerosol discharged to the outside through the discharge port 123c of the accommodation part 123 can move to the outside of the vaporizer 1 along the connecting passage 125b of the connecting part 125. Also, the connecting passage 125b of the connecting part 125 is connected to the main body 2 of the aerosol generating device 1000 and moves the aerosol along an air flow passage (not shown) formed in the main body 2. The aerosol moved along the air flow passage can be discharged to the outside of the aerosol generating device 1000.

[0063] FIG. 3 is a plan view of a heating chamber according to an embodiment.

[0064] FIG. 3 schematically shows a heating chamber 120 in which a core 121 around which a coil 122 is wound is accommodated in an accommodation part 123. The core 121 around which the coil 122 is wound can be accommodated in an accommodation groove 123b of the accommodation part 123.

[0065] The configurations of the core 121, the coil 122, and the accommodation part 123 included in the heating chamber 120 will be described below with reference to FIGS. 4 and 5. FIG. 4 schematically shows a cross-sectional view of a coil and a core according to an embodiment.

[0066] Referring to FIG. 4, the coil 122 has a wire diameter d of 0.15 mm to 0.2 mm c (diameter of wire), and the coil 122 can be wound around the core 121 six to nine times. In such a case, the ohmic loss in the coil 122 is also less than 8 W (Watt). In terms of deriving the maximum amount of atomization with a minimum amount of power, this is desirable, and in the above-mentioned range, the risk of defects and shorts in the coil 122 can be minimized.

[0067] Also, the electrical resistance of the coil 122 is 1.1 to 1.25 ohms. When the resistance is higher than the above range, there is a problem that the power efficiency is not good, the consumption amount of the aerosol generating substance is reduced, and a sufficient amount of atomization cannot be provided.

[0068] The wire diameter d of the coil 122 c is the diameter of the wire forming the coil 122 and may correspond to the thickness of the coil 122 itself. The number of winding turns of the coil 122 may mean the number of complete turns wound around the core 121.

[0069] The coil 122 wound around the core 121 has a straight-line coil 122 length l c(length of coil), and may have a winding interval a. That is, the coil 122 length l c may mean the straight length of the coil 122 wound along the longitudinal direction of the core 121 (e.g., the y-axis direction). As an embodiment, the coil 122 may be wound around the core so as to have a coil 122 length (length of coil) of 3 mm to 3.8 mm.

[0070] The winding interval a is the interval between turns of the wound coil 122 and may mean the pitch of the coil 122. As an embodiment, the winding interval of the coil 122 wound around the core is also 0.46 mm to 0.55 mm.

[0071] For example, in FIG. 4, the coil 122 is wound around the core 121 seven times, where the coil 122 length l c may have a value between 6 times and 7 times the winding interval a.

[0072] The core 121 has a certain range of length l w , and a certain range of diameter d w has.

[0073] For example, the length l of the core 121 w is also 8.3 mm to 9.7 mm.

[0074] The coil 122 is wound around the core 121. Specifically, the coil 122 is wound around the outer peripheral surface of the core 121, and the core 121 can be fitted into the wound coil 122. As a specific embodiment, the coil 122 can be wound around the core 121 so as to compress the core 121, or the compressed core 121 can be fitted into the wound coil 122.

[0075] The diameter d of the core 121 w is the non-compressed diameter d before the core 121 and the coil 122 are combined w1 , and the compressed diameter d after the core 121 and the coil 122 are combined w2 may have.

[0076] In such a case, the diameter d of the core 121 w is larger before being coupled to the coil 122, and is smaller after being coupled to the coil 122. That is, the uncompressed diameter d w1 is the compressed diameter d of the core 121 after the core 121 and the coil 122 are joined together. w2 For example, the uncompressed diameter d w1 is 2.4 mm to 2.6 mm, and the compressed diameter d w2 is also 1.85 mm to 2.15 mm. The uncompressed diameter d of the core 121 w1 In the compression diameter d w2 The compression ratio for is about 10% to 29%. If the compression ratio is higher than the range, there is a risk of the coil shorting out.

[0077] In another embodiment, the winding intervals a of the coils 122 wound around the core 121 may be the same or may be partially different from each other.

[0078] FIG. 5 is a schematic cross-sectional view of a housing according to one embodiment.

[0079] 5, the receiving portion 123 has a receiving groove 123b for receiving the core 121 (FIG. 3), and the core 121 (FIG. 3) around which the coil 122 (FIG. 3) is wound may be placed inside the receiving groove 123b of the receiving portion 123. The receiving groove 123b has a length of 1 r is 10 mm to 13 mm, and the width W r1 may have a receiving groove of 2.4 mm to 3.0 mm.

[0080] The receiving groove 123b may have a shape capable of receiving the lead 121 (FIG. 3). For example, the lead 121 (FIG. 3) may be cylindrical, and the receiving groove 123b may have a rectangular parallelepiped space capable of receiving it. As a specific example, the length l of the lead 121 (FIG. 3) may be 1 / 100,000,000. w is 8.3 mm to 9.7 mm, and the uncompressed diameter d of the core 121 (FIG. 3) w1is also 2.4 mm to 2.6 mm. Further, the length l of the accommodation groove 123b that accommodates the core 121 (FIG. 3) r is 10 mm to 13 mm, and the width W r1 is also 2.4 mm to 3.0 mm.

[0081] The accommodation groove 123b has a length l w and an uncompressed diameter d w1 that is the same as or slightly larger than the length l r and width W r1 of the core 121 (FIG. 3) so that the core 121 (FIG. 3) can be fixed. Alternatively, the accommodation groove 123b has a length l w and an uncompressed diameter d w1 greater than the length l r and width W r1 of the core 121 (FIG. 3) and includes a separate fixing member (not shown) that can fix the core 121 (FIG. 3). Here, fixing the core 121 (FIG. 3) may mean mounting it to such an extent that the core 121 (FIG. 3) does not come out of the accommodation groove 123b of the accommodation part 123 even with the movement of the vaporizer 1 or the aerosol generating device 1000 including the same.

[0082] As another example, as shown in FIG. 5, the width W of the accommodation groove 123b that accommodates the portion of the core 121 (FIG. 3) where the coil 122 (FIG. 3) is not wound around the core 121 (FIG. 3) r1 is even narrower than the width W of the accommodation groove 123b that accommodates the portion of the core 121 (FIG. 3) where the coil 122 (FIG. 3) is wound around the core 121 (FIG. 3), but is not limited thereto. r2

[0083] Note that the accommodation groove 123b in the accommodation part 123 may further include a separate fixing member (not shown) that can fix the core 121 (FIG. 3).

[0084] FIG. 6 is a block diagram of an aerosol generating device 600 according to another embodiment.

[0085] ​The aerosol generating device 600 also includes a control unit 610, a sensing unit 620, an output unit 630, a battery 640, a heater 650, a user input unit 660, a memory 670, and a communication unit 680. However, the internal structure of the aerosol generating device 600 is not limited to what is shown in FIG. 6. That is, depending on the design of the aerosol generating device 600, some of the components shown in FIG. 6 may be omitted, or new components may be further added. This should be understandable to those with ordinary knowledge in the technical field related to this embodiment.

[0086] The sensing unit 620 can sense the state of the aerosol generating device 600 or the state around the aerosol generating device 600 and transmit the sensed information to the control unit 610. Based on the sensed information, the control unit 610 can control the aerosol generating device 600 so that various functions such as controlling the operation of the heater 650, restricting smoking, determining whether an aerosol generating article (e.g., cigarette, cartridge, etc.) is inserted, and displaying notifications are performed.

[0087] The sensing unit 620 includes at least one of a temperature sensor 622, an insertion sensing sensor 624, and a puff sensor 626, but is not limited thereto.

[0088] The temperature sensor 622 can sense the temperature at which the heater 650 (or the aerosol generating substance) is heated. The aerosol generating device 600 may include a separate temperature sensor for sensing the temperature of the heater 650, or the heater 650 itself may serve as a temperature sensor. Alternatively, the temperature sensor 622 may be arranged around the battery 640 to monitor the temperature of the battery 640.

[0089] The insertion detection sensor 624 can detect the insertion and / or removal of the aerosol generating article.
