Referring to fig. 1, the aerosol-generating device 1 may comprise a battery 11, a control unit 12 and an induction coil 13. Referring to fig. 2 and 3, the aerosol-generating device 1 may further comprise a cartridge 14. An insertion space S may be formed inside the aerosol-generating device 1. The smoke 2 may be inserted into the insertion space S. The insertion space S may have a cylindrical shape and be opened to one side.
The aerosol-generating device 1 shown in fig. 1 to 3 shows components related to the present embodiment. Accordingly, it will be appreciated by those skilled in the art to which this embodiment relates that other general components than those shown in fig. 1 to 3 may be included in the aerosol-generating device 1.
Referring to fig. 1, the battery 11, the controller 12, and the induction coil 13 may be arranged in a line. Referring to fig. 2, the battery 11, the controller 12, the cartridge 14, and the induction coil 13 may be arranged in a row in the vertical direction. Referring to fig. 3, the cartridge 14 and the induction coil 13 may be arranged in parallel. However, the internal structure of the aerosol-generating device 1 is not limited to those shown in fig. 1 to 3. In other words, the arrangement of the battery 11, the control unit 12, the induction coil 13 and the cartridge 14 may be changed depending on the design of the aerosol-generating device 1.
The battery 11 may supply electrical power for operating the aerosol-generating device 1. For example, the battery 11 may supply power so that the induction coil 13 or the heater in the cartridge 14 may be heated, and may supply power required for the operation of the control unit 12. Further, the battery 11 may supply power required to operate a display, a sensor, a motor, etc. mounted in the aerosol-generating device 1.
The control unit 12 may control the overall operation of the aerosol-generating device 1. In particular, the control unit 12 may control the operation of the battery 11, the induction coil 13 and the cartridge 14, as well as other components comprised in the aerosol-generating device 1. Furthermore, the control unit 12 may determine whether the aerosol-generating device 1 is in an operable state by checking the state of each of the components of the aerosol-generating device 1.
The controller 12 may include at least one processor. A processor may be implemented as an array of multiple logic gates, or as a combination of a general purpose microprocessor and a memory storing a program executable in the microprocessor. Furthermore, those of ordinary skill in the art will appreciate that the processor may be implemented in other types of hardware.
The induction coil 13 may receive current from the battery 11. The induction coil 13 may be disposed around the insertion space S. The induction coil 13 may be wound around the insertion space S. The induction coil 13 may generate eddy current in the conductive metal disposed in the insertion space S, thereby inductively heating the metal.
The cartridge 14 may heat the liquid composition to generate an aerosol that may be delivered to a user through the smoke 2. In other words, the aerosol generated by the cartridge 14 may travel along an airflow channel of the aerosol-generating device 1, wherein the airflow channel may be formed such that the aerosol generated by the cartridge 14 passes through the smoke 2 to the user.
For example, cartridge 14 may include, but is not limited to, a reservoir, a liquid delivery device, and a heating element. For example, the reservoir, the liquid delivery device and the heating element may be included as separate modules in the aerosol-generating device 1.
The reservoir may store a liquid composition. For example, the liquid composition may be a liquid comprising a tobacco-containing material that includes volatile tobacco flavor components, or may be a liquid comprising a non-tobacco material. The reservoir may be manufactured to be detachable from the cartridge 14 or may be manufactured integrally with the cartridge 14.
For example, the liquid composition may include water, solvents, ethanol, plant extracts, spices, flavors, or vitamin mixtures. The flavoring may include, but is not limited to, menthol, peppermint, spearmint oil, various fruit flavoring ingredients, and the like. Flavoring agents may include ingredients capable of providing a variety of fragrances to a user. The vitamin mixture may be a mixture of at least one of vitamin a, vitamin B, vitamin C, and vitamin E, but is not limited thereto. The liquid composition may also include aerosol formers such as glycerin and propylene glycol.
The liquid delivery device may deliver the liquid composition of the reservoir to the heating element. For example, the liquid delivery device may be, but is not limited to, a core such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic.
The heating element is an element for heating a liquid composition delivered by the liquid delivery device. For example, the heating element may be a metal heating wire, a metal heating plate, a ceramic heater, or the like, but is not limited thereto. Furthermore, the heating element may be composed of conductive filaments (such as nichrome wires) and may be arranged in a structure wound around the liquid delivery device. The heating element may be heated by applying an electric current and the heating element may transfer heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. Thus, an aerosol can be generated.
For example, cartridge 14 may be referred to as, but is not limited to, an atomizer or nebulizer.
Meanwhile, the aerosol-generating device 1 may comprise general components in addition to the battery 11, the control unit 12, the induction coil 13 and the cartridge 14. For example, the aerosol-generating device 1 may comprise a display capable of outputting visual information and/or a motor for outputting tactile information. Furthermore, the aerosol-generating device 1 may comprise at least one sensor (suction detection sensor, temperature sensor, smoke insertion detection sensor, etc.). Further, the aerosol-generating device 1 may be manufactured to have a structure in which external air or internal gas may be introduced and may flow out even in a state in which the smoke 2 is inserted.
The smoke 2 may include a tobacco rod 21 (see fig. 4) and a filter rod 22 (see fig. 4) therein. The side of the tobacco rod 21 (see fig. 4) of the cigarette 2 is inserted into the insertion space S, and the other side of the cigarette 2 may protrude outside the aerosol-generating device 1. The smoke 2 may also include a metal foil 246 (see fig. 6) surrounding the tobacco rod 21 (see fig. 4). When the smoke 2 is inserted into the insertion space S, the aerosol-generating device 1 may operate the induction coil 13 and/or the cartridge 14 to generate an aerosol. The induction coil 13 may inductively heat the metal foil 246 (see fig. 6). The metal foil 246 (see fig. 6) can be heated by a magnetic field generated by an AC current flowing through the induction coil 13. The magnetic field may pass through the metal foil 246 (see fig. 6) to generate eddy currents in the metal foil 246 (see fig. 6). The current may generate heat in the metal foil 246 (see fig. 6). The metal foil 246 (see fig. 6) heated by the induction coil 13 can heat the medium so that an aerosol is generated. Aerosol generated by the induction coil 13 and/or the cartridge 14 may pass through the smoke 2 and be delivered to the user.
The user can inhale the aerosol in a state of biting the other side of the smoke 2 protruding to the outside from the insertion space S with the mouth. At this time, an aerosol is generated as the external air passes through the smoke 2, and the generated aerosol passes through the other side of the smoke and is delivered into the user's mouth.
As an example, the external air may be introduced through at least one air channel formed in the aerosol-generating device 1. For example, the opening and closing of the air channels and/or the size of the air channels formed in the aerosol-generating device 1 may be adjusted by the user. Thus, the amount of spray, smoking sensation, etc. can be adjusted by the user. As another example, external air may be introduced into the smoke 2 through at least one hole formed on the surface of the smoke 2.
Referring to fig. 4, the smoke 2 may include a tobacco rod 21 and a filter rod 22. The smoke 2 may comprise a tobacco rod 21 on one side and a filter rod 22 on the other side.
Although the filter rod 22 is shown as a single segment in fig. 4, it is not so limited. In other words, the filter rod 22 may be composed of a plurality of segments. For example, the filter rod 22 may include a segment for cooling the aerosol and a segment for filtering a predetermined component contained in the aerosol. Furthermore, if desired, the filter rod 22 may also include at least one segment that performs another function.
The diameter of the smoke 2 is in the range of 5mm to 9mm, and the length may be about 48mm, but is not limited thereto. For example, the length of the tobacco rod 21 is about 12mm, the length of the first section of the filter rod 22 is about 10mm, the length of the second section of the filter rod 22 is about 14mm, and the length of the filter rod 22 is about 14mm. The length of the third segment may be about 12mm, but is not limited thereto.
The smoke 2 may be wrapped by at least one wrapper 24. At least one hole through which external air is introduced or internal gas is discharged may be formed in the wrapper 24. As an example, the smoke 2 may be wrapped by a wrapper 24. As another example, the smoke 2 may be wrapped in an overlapping manner by two or more wrappers 24. For example, the tobacco rod 21 may be wrapped by a first wrapper 241, and the filter rod 22 may be wrapped by wrappers 242, 243, and 244. Furthermore, the entire smoke 2 may be repackaged by a single wrapper 245. If the filter rod 22 is comprised of a plurality of segments, each segment may be wrapped by wrappers 242, 243, and 244.
The first wrapper 241 and the second wrapper 242 may be made of a common filter wrapper. For example, the first and second wrappers 241, 242 may be porous or non-porous wrappers. Further, the first wrapper 241 and the second wrapper 242 may be made of paper having oil resistance and/or an aluminum laminate packaging material.
The third wrapper 243 may be made of hard wrap paper. For example, the basis weight of the third wrapper 243 may be comprised in the range of 88g/m 2 to 96g/m 2, preferably in the range of 90g/m 2 to 94g/m 2. Further, the thickness of the third wrapper 243 may be comprised in the range of 120um to 130um, preferably 125um.
The fourth wrap 244 may be made of an oil resistant hard wrap. For example, the basis weight of the fourth wrapper 244 may be comprised in the range of 88g/m 2 to 96g/m 2, preferably in the range of 90g/m 2 to 94g/m 2. Further, the thickness of the fourth wrap 244 may be comprised in the range of 120um to 130um, preferably 125um.
The fifth wrapper 245 may be made of sterile paper (MFW). Here, the aseptic paper (MFW) may refer to paper specially prepared to have improved tensile strength, water resistance, smoothness, etc. as compared to plain paper. For example, the basis weight of the fifth wrapper 245 may be comprised in the range of 57g/m 2 to 63g/m 2, preferably 60g/m 2. Further, the thickness of the fifth wrapper 245 may be comprised in the range of 64um to 70um, preferably 67um.
The predetermined material may be internally added to the fifth wrapper 245. Here, an example of the predetermined material may be silicon, but is not limited thereto. For example, silicon has the following characteristics: such as heat resistance with little change in temperature; oxidation resistance against oxidation; resistance to various chemicals; waterproof properties against water; or electrical insulation. However, any material having the above characteristics may be applied (or coated) on the fifth wrapper 245 even if it is not silicon, without limitation.
The fifth wrapper 245 may prevent the smoke 2 from burning. For example, when the tobacco rod 21 is heated by the heater 13, there is a possibility that the smoke 2 burns. Specifically, when the temperature rises above the ignition point of any one of the materials contained in the tobacco rod 21, the smoke 2 may burn. Even in this case, since the fifth wrapper 245 includes a non-combustible material, the burning phenomenon of the smoke 2 can be prevented.
In addition, the fifth wrapper 245 may prevent the aerosol-generating device 1 from being contaminated by substances generated in the smoke 2. By suction by the user, a liquid substance can be produced in the smoke 2. For example, a liquid substance (e.g., moisture, etc.) may be generated by cooling an aerosol generated in the smoke 2 by means of external air. When the fifth wrapper 245 wraps the smoke 2, liquid substances generated in the smoke 2 can be prevented from leaking out of the smoke 2.
The tobacco rod 21 may comprise an aerosol-generating material. The aerosol-generating material may be referred to as a medium. For example, the aerosol-generating material may include, but is not limited to, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. In addition, the tobacco rod 21 may contain other additive materials such as flavoring agents, humectants, and/or organic acids. In addition, a flavoring liquid such as menthol or a humectant may be added to the tobacco rod 21 by being sprayed onto the tobacco rod 21.
The tobacco rod 21 may be manufactured in various ways. For example, the tobacco rod 21 may be manufactured as a sheet or strand. In addition, the tobacco rod 21 may be made of cut filler formed by cutting tobacco sheets. Furthermore, the tobacco rod 21 may be surrounded by a thermally conductive material. For example, the thermally conductive material may be, but is not limited to, a metal foil such as aluminum foil. For example, the thermally conductive material surrounding the tobacco rod 21 may enhance the thermal conductivity applied to the tobacco rod by uniformly distributing the heat transferred to the tobacco rod 21, thereby improving the tobacco flavor. Furthermore, the thermally conductive material surrounding the tobacco rod 21 may act as a susceptor that is heated by an inductively heated heater. Although not shown in the figures, the tobacco rod 21 may include additional susceptors in addition to the heat conducting material surrounding the exterior.
The filter rod 22 may be a cellulose acetate filter. On the other hand, the shape of the filter rod 22 is not limited. For example, the filter rod 22 may be a cylindrical rod or a tubular rod including a hollow portion therein. Further, the filter rod 22 may be a recessed rod. If the filter rod 22 is made up of multiple segments, at least one of the multiple segments may be manufactured in a different shape.
The first segment of the filter rod 22 may be a cellulose acetate filter. For example, the first segment may be a tubular structure including a hollow portion therein. When the heater 13 is inserted by the first section, the internal material of the tobacco rod 21 can be prevented from being pushed back, and the cooling effect of the aerosol can be generated. The diameter of the hollow included in the first segment may be a suitable diameter in the range of 2mm to 4.5mm, but is not limited thereto.
The length of the first section may be a suitable length in the range of 4mm to 30mm, but is not limited thereto. Preferably, the length of the first segment may be 10mm, but is not limited thereto.
In the manufacture of the first segment, the hardness of the first segment may be adjusted by adjusting the content of the plasticizer. Further, the first segment may be manufactured by inserting structures such as membranes or tubes of the same or different materials inside (e.g. hollow).
The second section of the filter rod 22 cools the aerosol generated by the heating of the tobacco rod 21 by the heater 13. Thus, the user can inhale the aerosol cooled to an appropriate temperature.
The length or diameter of the second segment may be determined differently depending on the shape of the smoke 2. For example, the length of the second segment in the range of 7mm to 20mm may be suitably applied. Preferably, the length of the second segment may be about 14mm, but is not limited thereto.
The second segment may be manufactured by braiding polymer fibers. In this case, the fragrant liquid may be applied to the fibers made of the polymer. Alternatively, the second segment may be manufactured by braiding together individual fibers to which the flavouring liquid is applied and fibers made of a polymer. Alternatively, the second segment may be formed from a curled polymer sheet.
For example, the polymer may be made of a material selected from the group consisting of: polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polylactic acid (PLA), cellulose Acetate (CA), and aluminum foil.
Since the second segment is formed of woven polymer fibers or crimped polymer sheets, the second segment may comprise a single or multiple passages extending in the longitudinal direction. Here, a passageway may refer to a channel through which a gas (e.g., air or aerosol) passes.
For example, the second segment of the curled polymeric sheet may be formed of a material having a thickness between about 5 μm and about 300 μm (such as between about 10 μm and about 250 μm). Further, the total surface area of the second segment may be between about 300mm 2/mm and about 1000mm 2/mm. Furthermore, the aerosol-cooling element may be formed from a material having a specific surface area of between about 10mm 2/mg and about 100mm 2/mg.
Meanwhile, the second segment may include a thread containing volatile aroma components. Here, the volatile fragrance component may be menthol, but is not limited thereto. For example, the thread may be filled with a sufficient amount of menthol to provide at least 1.5mg of menthol to the second segment.
The third segment of the filter rod 22 may be a cellulose acetate filter. The length of the third segment in the range of 4mm to 20mm may be suitably employed. For example, the length of the third segment may be about 12mm, but is not limited thereto.
During the manufacture of the third segment, it may be manufactured such that the scent is generated by spraying a flavouring liquid on the third segment. Alternatively, individual fibers coated with a flavoring liquid may be inserted into the third segment. The aerosol generated by the tobacco rod 21 is cooled as it passes through the second section of the filter rod 22, and the cooled aerosol is delivered to the user through the third section. Thus, when a flavouring element is added to the third segment, an effect of enhancing the durability of the fragrance delivered to the user may occur.
Furthermore, the filter rod 22 may comprise at least one capsule 23. Here, the capsule 23 may perform a function of generating a fragrance or may perform a function of generating an aerosol. For example, the capsule 23 may have a structure in which a liquid containing a perfume is wrapped with a film. The capsule 23 may have a spherical or cylindrical shape, but is not limited thereto.
Referring to fig. 5, the smoke 3 may further comprise a front plug 33. The front plug 33 may be located on the opposite side of the tobacco rod 31 from the filter rod 32. The front plug 33 prevents the tobacco rod 31 from backing out. The front plug may prevent the aerosol liquefied from the tobacco rod 31 during smoking from flowing into the aerosol-generating device 1 (see fig. 1-3).
The filter rod 32 may include a first section 321 and a second section 322. Here, the first section 321 may correspond to the first section of the filter rod 22 of fig. 4, and the second section 322 may correspond to the third section of the filter rod 22 of fig. 4.
The diameter and the overall length of the smoke 3 may correspond to the diameter and the overall length of the smoke 2 of fig. 4. For example, the front plug 33 may have a length of about 7mm, the tobacco rod 31 may have a length of about 15mm, the first section 321 may have a length of about 12mm, and the second section 322 may have a length of about 14mm. However, the present invention is not limited thereto.
The smoke 3 may be wrapped by at least one wrapper 35. At least one hole through which external air flows or internal gas flows may be formed in the wrap 35. For example, the front plug 33 is wrapped with a first wrapper 351, the tobacco rod 31 is wrapped with a second wrapper 352, and the first section 321 may be wrapped, and the second section 322 may be wrapped with a fourth wrapper 354. In addition, the entire smoke 3 may be repackaged by the fifth wrapper 355.
Further, at least one perforation 36 may be formed in the fifth wrapper 355. For example, perforations 36 may be formed in the area surrounding tobacco rod 31, but are not limited thereto. Perforations 36 may be used to transfer heat formed by heater 13 shown in fig. 2 and 3 to the interior of tobacco rod 31.
Moreover, second segment 322 may include at least one capsule 34. Here, the capsule 34 may perform a function of generating a fragrance or may perform a function of generating an aerosol. For example, the capsule 34 may have a structure in which a liquid containing a fragrance is wrapped with a film. The capsule 34 may have a spherical or cylindrical shape, but is not limited thereto.
The first wrapper 351 may be a universal filter wrapper in which metal foils, such as aluminum foil, are combined.

For example, silicon has the following characteristics: such as heat resistance with little change in temperature; oxidation resistance against oxidation; resistance to various chemicals; waterproof properties against water; or electrical insulation. However, any material having the above characteristics may be applied (or coated) on the fifth wrapper 355, even if not silicon, without limitation.
The front plug 33 may be made of cellulose acetate. As an example, the front plug 33 may be manufactured by adding a plasticizer (e.g., triacetin) to the cellulose acetate tow. The single denier of the filaments constituting the cellulose acetate tow may be included in the range of 1.0 to 10.0, and preferably it may be included in the range of 4.0 to 6.0.

Referring to fig. 6 and 7, only the corresponding portion of the tobacco rod 21 of the cigarette 2 is cut, showing the tobacco rod 21 wrapped. Hereinafter, the smoke 2 of fig. 4 will be described as an example, but it will be clearly understood by those skilled in the art that the description can be applied even when other tobacco rods (such as the tobacco rod 31 of the smoke 3 of fig. 5, etc.) are wrapped.
The first wrapper 241 may wrap the exterior of the tobacco rod 21. The tobacco rod 21 surrounded by the first wrapper 241 may be formed in a cylindrical shape having approximately a predetermined radius R. The first wrapper 241 may extend longer in the circumferential direction along the outer peripheral surface of the tobacco rod 21.
Referring to fig. 4, a metal foil 246 may be formed in a portion corresponding to the tobacco rod 21. The metal foil 246 may extend along the outer circumference of the first wrapper 241. The metal foil 246 may surround the outer circumference of the first wrapper 241. As another example, a metal foil 246 may surround the inner circumference of the first wrapper 241 (see fig. 12 and 13). The metal foil 246 may be adhered to the outer circumferential surface or the inner circumferential surface of the first wrapper 241. Alternatively, the metal foil 246 and the first wrapper 241 may be formed of paper.
The metal foil 246 may form a closed loop by contacting one side and the other side with respect to a circumferential direction of the metal foil 246. The metal foil 246 may have conductivity and predetermined resistance. The metal foil 246 may be heated by eddy currents generated by the induction coil 13 (see fig. 1 to 3). For example, the metal foil 246 may be aluminum foil. However, the present invention is not limited thereto.
The fifth wrapper 245 may form the exterior of the smoke 2. The fifth wrapper 245 may wrap around the outer circumferential surface of the first wrapper 241 and/or the metal foil 246. In the circumferential direction, an inner peripheral surface of one side of the fifth wrapper 245 and an outer peripheral surface of the other side of the fifth wrapper 245 may be adhered. The fifth wrapper 245 may protect the smoke 2 from external influences. The fifth wrapper 245 may be referred to as an overwrap 245. The portion corresponding to the tobacco rod 21 is formed of three layers, and the other portion may be formed of two layers.
Referring to fig. 8, the first wrapper 242 may extend to one side by a predetermined length L1. The metal foil 246 may extend as long as the predetermined length L2 to one side. The length L2 of the metal foil 246 may be greater than the length L1 of the first wrapper 242. One surface of the first wrapper 242 and the other surface of the metal foil 246 may contact or adhere to each other.
An end of one side 246a of the metal foil 246 (hereinafter, one end of the metal foil 246) may extend from an end of one side 242a of the first wrapper 242 (hereinafter, one end of the first wrapper 242) to one side by a predetermined length L4. One end of the metal foil 246 may be referred to as a first end of the metal foil 246. One end of the first wrapper 242 may be referred to as a first end of the first wrapper 242. In the state of fig. 8 (in which the metal foil 246 and the first wrapper 242 do not wrap the tobacco rod 21), one side 246a of the metal foil 246 may not overlap with the first wrapper 242 and protrude to one side. The other side 246b of the metal foil 246 may overlap the other side 242b of the first wrapper 242. The other end of the metal foil 246 and the other end of the first wrapper 242 may coincide. The other end of the metal foil 246 may be referred to as a second end of the metal foil 246. The other end of the first wrapper 242 may be referred to as the second end of the first wrapper 242.

The metal foil 246 may form a closed loop. The overwrap 245 may surround the outer peripheral surface of the metal foil 246. One side and the other side of the overwrap 245 may be adhered to each other.
Therefore, the following advantages can exist as compared to the case where the metal foil 246 is open-loop. First, it is possible to prevent discharge or spark that may occur when the induction coil 13 generates eddy current in the metal foil 246 to heat the metal foil 246. Further, when the induction coil 13 heats the metal foil 246, loss of current can be prevented. Further, by reducing the heat generation temperature error of the metal foil 246, the control accuracy is improved, and uniformity of the amount of aerosol or taste can be maintained.
The circumference of the tobacco rod 21 may be approximately equal to or approximate to a length C obtained by subtracting the length L3 of the overlap from the length L1 of the first wrapper 242. That is, if the radius of the tobacco rod 21 is R (refer to fig. 7), 2pi R and C, which are circumferences of the tobacco rod 21, may be substantially the same or approximate.
Referring to fig. 10, the first wrapper 242 may extend to one side by a predetermined length L10. The metal foil 246 may extend as long as the predetermined length L20 to one side.

One end of the metal foil 246 may extend a predetermined length L40 from one end of the first wrapper 242 to one side. In the state of fig. 10 (in which the metal foil 246 and the first wrapper 242 do not wrap the tobacco rod 21), one side 246a of the metal foil 246 does not overlap with the first wrapper 242 and protrudes to one side.
An end portion of the other side 242b of the first wrapper 242 (hereinafter, the other end of the first wrapper 242) may extend a predetermined length L30 from an end portion of the other side 246b of the metal foil 246 (hereinafter, the other end of the metal foil 246) to the other side. In the state of fig. 10 (in which the metal foil 246 and the first wrapper 242 do not wrap the tobacco rod 21), the other side 242b of the first wrapper 242 may not overlap the metal foil 246 and protrude toward the other side.
Referring to fig. 10 and 11, a first wrapper 242 may surround the tobacco rod 21. The metal foil 246 may surround the first wrapper 242 at the outer side of the first wrapper 242. Based on the circumferential direction, one end of the metal foil 246 may extend to one side from the end of the first wrapper 242 and protrude. The other end of the first wrapper 242 may extend from the other end of the metal foil 246 to the other side based on the circumferential direction.
An inner peripheral surface of one side 242a of the first wrapper 242 may contact or adhere to an outer peripheral surface of the other side 242b of the first wrapper 242. One side 242a and the other side 242b of the first wrapper 242 may overlap by a predetermined length L30.
An inner peripheral surface of one side 246a of the metal foil 246 may be in contact with or adhered to an outer peripheral surface of the other side 246b of the metal foil 246.

The metal foil 246 may form a closed loop.
Therefore, the following advantages can exist as compared to the case where the metal foil 246 is open-loop. First, it is possible to prevent discharge or spark that may occur when the induction coil 13 generates eddy current in the metal foil 246 to heat the metal foil 246. Further, when the induction coil 13 heats the metal foil 246, loss of current can be prevented. Further, by reducing the heat generation temperature error of the metal foil 246, the control accuracy is improved, and uniformity of the amount of aerosol or taste can be maintained.
The end of one side 242a of the first wrapper 242 may be in contact with the end of the other side 246b of the metal foil 246. The overwrap 245 may surround the outer peripheral surface of the metal foil 246. One side and the other side of the overwrap 245 may be adhered.
The circumference of the tobacco rod 21 may be approximately equal to or approximate to a length C obtained by subtracting the length L30 of the overlap from the length L10 of the first wrapper 242. That is, if the radius of the tobacco rod 21 is R (refer to fig. 7), 2pi R and C, which are circumferences of the tobacco rod 21, may be substantially the same or approximate.
Referring to fig. 10 and 12, a metal foil 246 may surround the tobacco rod 21. The metal foil 246 may surround the first wrapper 242 at the inner side of the wrapper 242. That is, in contrast to fig. 11, the metal foil 246 and the first wrapper 242 may be wrapped such that the metal foil 246 is in contact with the tobacco rod 21.
The outer circumferential surface of one side 242a of the first wrapper 242 may contact or adhere to the inner circumferential surface of the other side 242b of the first wrapper 242. One side 242a and the other side 242b of the first wrapper 242 may overlap by a predetermined length L30.
The outer circumferential surface of one side 246a of the metal foil 246 may be in contact with or adhered to the inner circumferential surface of the other side 246b of the metal foil 246. One side 246a and the other side 246b of the metal foil 246 may overlap by a predetermined length L40. One side 246a and the other side 246b of the metal foil 246 may be connected to each other. The metal foil 246 may form a closed loop.
