More particularly, one or more embodiments relate to an aerosol-generating device in which a separation guide hole for separating a separation member of the aerosol-generating device from a main body is not visible from the outside, thereby allowing easy separation of the separation member while improving the overall appearance of the aerosol-generating device.

Background

Recently, the need for alternative methods for overcoming the disadvantages of conventional cigarettes has increased. For example, there is an increasing need for systems for generating aerosols by heating cigarettes or aerosol-generating substances using an aerosol-generating device, rather than by burning cigarettes using an aerosol-generating device.

Components forming the aerosol-generating device, such as the heater and the user interface (e.g. Universal Serial Bus (USB) interface), need to be replaced or repaired depending on the reuse of the aerosol-generating device. For this purpose, it is necessary to first separate a separation member detachably coupled to the main body of the aerosol-generating device.

Fig. 1 shows the exterior of the aerosol-generating device according to an embodiment, and fig. 2 shows the aerosol-generating device of fig. 1 viewed in the y-axis direction.

Referring to fig. 1 and 2, an aerosol-generating device 100 according to an embodiment may comprise: the body 110, the separation member 120, and the receiving hole 121, the separation member 120 is detachably coupled to the body 110.

The body 110 may form the overall exterior of the aerosol-generating device 100, and the components of the aerosol-generating device 100 may be arranged in the body 110. For example, a receiving space, into which a cigarette may be inserted, a heater for heating the cigarette, and a user interface (e.g., a Universal Serial Bus (USB) interface) for electrically connecting the aerosol-generating device 100 to an external device, may be disposed in the body 110, but one or more embodiments are not limited thereto.

The separation member 120 may be detachably coupled to a portion of the body 110, and may protect components of the aerosol-generating device 100 disposed in the body 110. For example, while allowing the receiving hole 121, inserting an external device electrically connected to the aerosol-generating device 100 into the receiving hole 121 exposed to the outside, the separation member 120 may protect other components (e.g., a processor, a memory, etc.) of the aerosol-generating device 100, but one or more embodiments are not limited thereto.

The aerosol-generating device 100 according to the embodiment may be arranged in such a way that a separation guide hole (not shown) for separating or detaching the separation member 120 from the main body 110 is not exposed to the outside, and such an arrangement may help to fix the aesthetic properties of the aerosol-generating device 100 while allowing the separation member 120 of the aerosol-generating device 100 to be easily separated.

Fig. 3 is a view showing a structure in which the separation guide hole is arranged to be exposed to the outside of the separation member. Fig. 3 shows the aerosol-generating device 101 in which the separation guide hole 122a for separating the separation member 120a from the main body 110a is exposed to the outside.

Referring to fig. 3, when the separation guide hole 122a for separating the separation member 120a from the main body 110a is exposed on the outside of the aerosol-generating device 101, the aesthetic appearance of the aerosol-generating device 101 is reduced due to the separation guide hole 122a, and a gap between the main body 110a and the separation member 120a may be generated due to a tolerance.

In contrast, since the separation guide hole is not exposed to the outside in the aerosol-generating device (e.g., the aerosol-generating device 100 of fig. 1) according to the embodiment, both the aesthetic impression and the detachability of the aerosol-generating device can be ensured, and a detailed description thereof is provided in detail.

Fig. 4 shows a separating member of the aerosol-generating device according to an embodiment, seen in a first direction, and fig. 5 shows the separating member of the aerosol-generating device of fig. 4, seen in a second direction, opposite to the first direction.

Referring to fig. 4 and 5, the separation member 120 of the aerosol-generating device 100 according to an embodiment may comprise: the receiving hole 121, the separation guide hole 122, the barrier 123, and the coupling portion 124.

The receiving hole 121 may pass through the separation member 120 and receive an external device electrically connected to the aerosol-generating device 100. When the separation member 120 is coupled to the body 110, the receiving hole 121 may be recessed in a direction toward the body 110. When the separation member 120 is coupled to the body 110, the receiving hole 121 may be exposed on the outside of the aerosol-generating device 100. The external device may be a terminal of a charger for charging a battery included in the aerosol-generating device 100, and the charger may be of a USB type, but one or more embodiments are not limited thereto.

The separation guide hole 122 may communicate with the receiving hole 121 and extend in a direction different from the direction in which the receiving hole 121 extends. The direction in which the receiving hole 121 extends may refer to a direction in which the empty space extends. For example, the separation guide hole 122 may extend in a direction intersecting with a direction in which the receiving hole 121 extends.

In the separation guide hole 122, a separation tool for separating the separation member 120 may be inserted in a state where the separation member 120 is coupled to the main body 110. For example, a user may insert a separation tool (e.g., a driver) into the separation guide hole 122 to separate the separation member 120 from the body 110 according to the principle of leverage.

In this case, since the separation guide hole 122 extends in a direction different from the direction in which the receiving hole 121 extends, the separation guide hole 122 may be covered when the separation member 120 is viewed in the direction in which the receiving hole 121 extends; accordingly, the detachability of the separating member 120 may be maintained without degrading the overall aesthetics of the aerosol-generating device 100.

The separation guide hole 122 may be formed in a region where the separation member 120 intersects with an extension line of the long axis L of the cross section of the receiving hole 121. Here, the cross section of the receiving hole 121 may refer to a cross section in a direction intersecting with a direction in which the receiving hole 121 extends. In addition, the long axis L may be an axis having the maximum length in a cross section of the receiving hole 121. Since the separation guide hole 122 is formed in the region where the separation member 120 intersects with the extension line of the long axis L of the cross section of the receiving hole 121, the hiding ability of the separation guide hole 122 can be improved. Further, since the operation range of the separation tool inserted into the separation guide hole 122 can be increased, the detachability of the separation member 120 can be improved.

The separation member 120 may include: a coupling portion 124 and a barrier 123, the coupling portion 124 being coupled to the body 110; the barrier 123 is disposed between the separation guide hole 122 and the coupling portion 124.

The coupling portion 124 may be coupled to the body 110 in at least one of a snap-fit manner, a magnetic coupling method, and an interference fit manner, but the coupling manner in which the coupling portion 124 is coupled to the body 110 is not limited to the above examples.

The barrier 123 may have a shape protruding in a direction in which the receiving hole 121 extends. The barrier 123 may prevent external impurities from penetrating into the inside of the body 110 through the separation guide hole 122. The barrier 123 can also prevent the separation tool D inserted in the direction in which the separation guide hole 122 extends from being further inserted. Thus, the barrier 123 may contact the end of the separation tool D and correspond to a point of action in a lever principle using the separation tool D as a lever. Since the barrier 123 is disposed between the separation guide hole 122 and the coupling portion 124, the force generated by the separation tool D can be effectively transmitted toward the coupling portion 124.

Referring to fig. 6, when the aerosol-generating device 100 according to the embodiment is viewed in a direction toward the receiving hole 121 in the separation member 120, the separation guide hole 122 is not exposed to the outside, and thus, the aesthetic properties of the aerosol-generating device 100 are not degraded by the separation guide hole 122.

Further, when the aerosol-generating device 100 according to the embodiment includes the separation guide hole 122 while maintaining its beauty, the separation member 120 can be detached from the main body 110 as needed without causing any damage.

In addition, since the separation member 120 can be easily separated from the main body 110, a user can easily replace components of the aerosol-generating device 100, and thus, convenience of maintenance and/or repair can be improved.

Fig. 7 is an x-y plan cross-sectional view showing the insertion of a separation tool into the aerosol-generating device of fig. 1.

Referring to fig. 7, the separation tool D may be inserted into the separation guide hole 122. The separation guide hole 122 may extend in a direction intersecting with a direction in which the receiving hole 121 extends. The separation tool D (e.g., a driver) may be inserted into an area where the separation guide hole 122 extends, and when the separation tool D inserted into the separation guide hole 122 is pressed in the direction of the arrow of fig. 7, the separation member 120 may be separated from the main body 110 according to the principle of the lever.

The first distance d1 from the separation guide hole 122 to the barrier 123 and the second distance d2 from the separation guide hole 122 to the coupling portion 124 may each have a length ratio of about 1:3 to about 1:15. Since each of the first distance D1 and the second distance D2 has the above-described length ratio, the separation member 120 can be easily separated from the main body 110 by using the separation tool D. Moreover, each of the first distance d1 and the second distance d2 may have a length ratio of about 1:5 to about 1:12.

The opening end portion of the separation guide hole 122 may have a length of from about 0.3mm to about 3mm in the direction in which the receiving hole 121 extends. Here, the open end portion may refer to an entrance of the separation guide hole 122 into which the separation tool D is inserted into the separation guide hole 122. Also, the separation guide hole 122 may have a length of from about 0.5mm to about 1.5mm in a direction toward the main body 110.

The aerosol-generating device 100 according to the embodiment may comprise a protection member 131, the protection member 131 being arranged inside the receiving hole 121 and surrounding at least a portion of a side surface of the receiving hole 121. The protection member 131 may protect components accommodated in the accommodation hole 121 exposed to the outside of the aerosol-generating device 100.

The protection member 131 may block a portion of the opening end portion of the separation guide hole 122. When the protection member 131 blocks a portion of the separation guide hole 122, the protection member 131 may contact the separation tool D inserted into the separation guide hole 122. The portion of the protection member 131 contacting the separation tool D may correspond to a supporting point in a lever principle in which the separation tool D functions as a lever.

The receiving hole 121 may receive the interface terminal 130 that receives power from an external device. The aerosol-generating device may be electrically connected to an external device through the interface terminal 130. In addition, the interface terminal 130 may be connected to an external device and receive/transmit information from/to the external device.

The interface terminal 130 may include a USB terminal. The USB terminal may be, for example, a micro USB 5 pin terminal, a USB C terminal, a USB B terminal, or a USB a terminal, but is not limited thereto.

Hereinafter, an example of an aerosol-generating device according to an embodiment is described.

Figures 8 to 10 show examples of the insertion of cigarettes into an aerosol-generating device.

Referring to fig. 8, the aerosol-generating device 100 comprises: a battery 140, a controller 150, and a heater 160. Referring to fig. 9 and 10, the aerosol-generating device 100 further comprises a vaporiser 170. In addition, the cigarette 200 may be inserted into the interior space of the aerosol-generating device 100.

Fig. 8 to 10 show an aerosol-generating device 100 comprising components related to the present embodiment. Accordingly, those of ordinary skill in the art relating to this embodiment will appreciate that other general components may be included in the aerosol-generating device 100 in addition to those illustrated in fig. 8-10.

In addition, fig. 9 and 10 show that the heater 160 is included in the aerosol-generating device 100, but the heater 160 may be omitted as required.

Fig. 8 shows a series arrangement of a battery 140, a controller 150 and a heater 160. In addition, fig. 9 shows that the battery 140, the controller 150, the vaporizer 170, and the heater 160 are arranged in series. In addition, fig. 10 shows that the vaporizer 170 and the heater 160 are arranged in parallel. However, the internal structure of the aerosol-generating device 100 is not limited to the structure shown in fig. 8 to 10. In other words, the battery 140, the controller 150, the heater 160, and the vaporizer 170 may be differently arranged according to the design of the aerosol-generating device 100.

When the cigarette 200 is inserted into the aerosol-generating device 100, the aerosol-generating device 100 may operate the heater 160 and/or the vaporizer 170 to generate the aerosol. The aerosol generated by the heater 160 and/or vaporizer 170 may be delivered to a user by passing through the cigarette 200.

The aerosol-generating device 100 may heat the heater 160, as desired, even when the cigarette 200 is not inserted into the aerosol-generating device 100.

The battery 140 supplies electrical power for operating the aerosol-generating device 100. For example, the battery 140 may supply power to heat the heater 160 or the vaporizer 170, and may supply power for operating the controller 150. Further, the battery 140 may supply power for operating a display, a sensor, a motor, etc. installed in the aerosol-generating device 100.

The controller 150 generally controls the operation of the aerosol-generating device 100. In detail, the controller 150 may control not only the operation of the battery 140, the heater 160, and the vaporizer 170, but also the operation of other components included in the aerosol-generating device. In addition, the controller 150 may check the status of each component in the aerosol-generating device 100 to determine whether the aerosol-generating device 100 is operational.

The controller 150 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 by the microprocessor. Those of ordinary skill in the art will appreciate that a processor may be implemented in other forms of hardware.

The heater 160 may be heated by power supplied from the battery 140. For example, the heater 160 may be located outside of the cigarette when the cigarette is inserted into the aerosol-generating device 100. Thus, the heated heater 160 may increase the temperature of the aerosol-generating substance in the cigarette.

The heater 160 may include a resistive heater. For example, the heater 160 may include conductive tracks, and the heater 160 may be heated when current flows through the conductive tracks. However, the heater 160 is not limited to the example described above and the heater 160 may include all heaters that may be heated to a desired temperature. Here, the desired temperature may be preset in the aerosol-generating device 100 or may be set at a temperature desired by the user.

As another example, the heater 160 may comprise an induction heater. In detail, the heater 160 may include a conductive coil for heating the cigarette in an induction heating method, and the cigarette may include a base that may be heated by the induction heater.

For example, the heater 160 may include a tube-type heating element, a plate-type heating element, a needle-type heating element, or a rod-type heating element, and may heat the inside or outside of the cigarette 200 according to the shape of the heating element.

Moreover, the aerosol-generating device 100 may comprise a plurality of heaters 160. Here, the plurality of heaters 160 may be inserted into the cigarette 200 or may be disposed outside the cigarette 200. Further, some of the plurality of heaters 160 may be inserted into the cigarette 200, while other heaters 160 may be disposed outside of the cigarette 200. In addition, the shape of the heater 160 is not limited to the shape shown in fig. 8 to 10, but may include various shapes.

The vaporizer 170 may generate an aerosol by heating the liquid composition, and the generated aerosol may pass through the cigarette 200 to be delivered to the user. In other words, the aerosol generated via the vaporizer 170 may move along the airflow channel of the aerosol-generating device 100, and the airflow channel may be configured such that the aerosol generated via the vaporizer 170 may pass through a cigarette to be delivered to a user.

For example, the vaporizer 170 may include: the liquid storage part, the liquid transfer member, and the heating member, but are not limited thereto. For example, the liquid reservoir, the liquid transfer element, and the heating element may be included in the aerosol-generating device 100 as separate modules.

The liquid storage part may store the liquid composition. For example, the liquid composition may be a liquid comprising tobacco-containing materials having volatile tobacco aroma components, or may be a liquid comprising non-tobacco materials. The liquid storage part may be formed to be detachable from the vaporizer 170, or may be formed in an integral manner with the vaporizer 170.

For example, the liquid composition may include: water, solvents, ethanol, plant extracts, flavors, fragrances, or vitamin mixtures. The flavor may include menthol, peppermint, spearmint oil, and various fruity ingredients, but is not limited thereto. The flavoring agent may include ingredients capable of providing various flavors or tastes to the 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. In addition, the liquid composition may include aerosol-forming materials such as glycerin and propylene glycol.

The liquid delivery element may deliver the liquid composition in the liquid reservoir to the heating element. For example, the liquid transfer element may be a core such as cotton fibers, ceramic fibers, glass fibers, or gas permeable ceramics, but is not limited thereto.

The heating element is an element for heating the liquid composition delivered by the liquid delivery element. For example, the heating element may be a metal heating wire, a metal hot plate, a ceramic heater, or the like, but is not limited thereto. Additionally, the heating element may comprise a conductive wire such as nichrome wire and may be positioned to wrap around the liquid transport element. The heating element may be heated by a power source and may transfer heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, an aerosol may be generated.

For example, the vaporizer 170 may be referred to as a two-in-one cartridge (cartomizer) or atomizer, but is not limited thereto.

The aerosol-generating device 100 may include general components in addition to the battery 140, the controller 150, the heater 160, and the vaporizer 170. For example, the aerosol-generating device 100 may comprise a display capable of outputting visual information and/or a motor for outputting tactile information. In addition, the aerosol-generating device 100 may comprise at least one sensor (puff detection sensor, temperature detection sensor, cigarette insertion detection sensor, etc.). Furthermore, the aerosol-generating device 100 may be formed in a structure such that: even when the cigarette 200 is inserted into the aerosol-generating device 100, external air may be introduced or internal air may be exhausted.

Although not shown in fig. 8-10, the aerosol-generating device 100 and the additional bracket member may together form a system. For example, the cradle member may be used to charge the battery 140 of the aerosol-generating device 100. Alternatively, the heater 160 may be heated when the bracket member and the aerosol-generating device 100 are coupled to each other.

The cigarette 200 may be similar to a conventional combustion cigarette. For example, the cigarette 200 may be divided into a first portion comprising aerosol-generating substance and a second portion comprising a filter or the like. Alternatively, the second portion of the cigarette 200 may also include an aerosol-generating substance. For example, an aerosol-generating substance in the form of particles or capsules may be inserted into the second portion.

The entire first portion may be inserted into the aerosol-generating device 100 and the second portion may be exposed to the outside. Alternatively, only a portion of the first portion may be inserted into the aerosol-generating device 100, or portions of the entire first and second portions may be inserted into the aerosol-generating device 100. The user may inhale the aerosol while holding the second portion with the user's mouth. In this case, the aerosol is generated by the external air passing through the first portion, and the generated aerosol passes through the second portion and is delivered into the mouth of the user.

For example, external 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 channel and/or the size of the air channel formed in the aerosol-generating device 100 may be adjusted by the user. Thus, the amount and quality of smoking can be adjusted by the user. As another example, outside air may flow into the cigarette 200 through at least one aperture formed in a surface of the cigarette 200.

Fig. 11 shows another example of an aerosol-generating device.

Referring to fig. 11, the aerosol-generating device 100 may comprise: a heater 160, a coil 161, a battery 140, and a controller 150. However, one or more embodiments are not limited thereto, and other general components besides those shown in fig. 11 may be included in the aerosol-generating device 100.

The aerosol-generating device 100 may generate an aerosol by heating an aerosol-generating article housed in the aerosol-generating device 100 according to an induction heating method. The induction heating method may represent a method of heating a magnetic substance by applying an alternating magnetic field whose direction is periodically changed, wherein the magnetic substance is heated by an external magnetic field.

When an alternating magnetic field is applied to a magnetic substance, energy may be lost in the magnetic substance due to eddy current loss and hysteresis loss, and the lost energy may be emitted from the magnetic substance as thermal energy. The greater the amplitude or frequency of the alternating magnetic field applied to the magnetic substance, the more thermal energy that can be emitted from the magnetic substance. When the aerosol-generating device 100 applies an alternating magnetic field to the magnetic substance, thermal energy may be emitted from the magnetic substance, and the thermal energy emitted from the magnetic substance may be transferred to the cigarette.

The magnetic substance heated by the external magnetic field may be a susceptor. The base may be included in the aerosol-generating device 100 in the form of a sheet, or strip. For example, at least some portions of the heater 160 inside the aerosol-generating device 100 may comprise a base material.

At least a portion of the base material may include a ferromagnetic substance. For example, the base material may comprise metal or carbon. The base material may include: at least one of ferrite, ferromagnetic alloy, stainless steel, and aluminum (Al). In addition, the base material may include at least one of ceramics such as graphite, molybdenum (Mo), silicon carbide, niobium (Nb), nickel (Ni) alloy), a metal film, or zirconia, transition metals such as Ni or cobalt (Co), and metalloids such as boron (B) or phosphorus (P).

The aerosol-generating device 100 may house an aerosol-generating article. In the aerosol-generating device 100, a space for accommodating an aerosol-generating article may be formed. In the space for accommodating the aerosol-generating article, a heater 160 may be arranged. For example, the heater 160 may include: the receiving space for receiving the aerosol-generating article has a cylindrical shape. Thus, when the aerosol-generating article is housed in the aerosol-generating device 100, the aerosol-generating article may be housed in the housing space of the heater 160.

The heater 160 may surround at least a portion of an outside surface of an aerosol-generating article housed in the aerosol-generating device 100. For example, the heater 160 may surround tobacco media included in the aerosol-generating article. Accordingly, heat may be efficiently transferred from the heater 160 to the tobacco media.

The heater 160 may heat the aerosol-generating article housed in the aerosol-generating device 100. As described above, the heater 160 may heat the aerosol-generating article in an induction heating method. The heater 160 may include a base material heated by an external magnetic field, and the aerosol-generating device 100 may apply an alternating magnetic field to the heater 160.

The coil 161 may be included in the aerosol-generating device 100. The coil 161 may apply an alternating magnetic field to the heater 160. When power is supplied from the aerosol-generating device 100 to the coil 161, a magnetic field may be generated in the coil 161. When an alternating current is applied to the coil 161, the direction of the magnetic field formed in the coil 161 may be gradually changed. When the heater 160 is located in the coil 161, the heater 160 may emit heat when the heater 160 is exposed to an alternating magnetic field having a periodically varying direction, and the aerosol-generating article housed in the housing space in the heater 160 may be heated.

The coil 161 may be wound along an outer side surface of the heater 160. Further, the coil 161 may be wound along the inner surface of the outer housing of the aerosol-generating device 100. When the coil 161 is wound, the heater 160 may be disposed in the formed inner space. When power is supplied to the coil 161, an alternating magnetic field generated by the coil 161 may be applied to the heater 160.

The coil 161 may extend in the length direction of the aerosol-generating device 100. The coil 161 may extend to an appropriate length in the length direction. For example, the coil 161 may extend to a length corresponding to the length of the heater 160, or to a length greater than the length of the heater 160.

The coil 161 may be disposed at a position suitable for applying an alternating magnetic field to the heater 160. For example, the coil 161 may be disposed at a position corresponding to the heater 160. Due to the size and arrangement of the coil 161, the efficiency of applying the alternating magnetic field of the coil 161 to the heater 160 can be improved.

The degree to which the heater 160 heats the aerosol-generating article may also be varied when the amplitude or frequency of the alternating magnetic field generated by the coil 161 is varied. Because the magnitude or frequency of the magnetic field generated by the coil 161 may vary depending on the power supplied to the coil 161, the aerosol-generating device 100 may control the heating of the aerosol-generating article by adjusting the power supplied to the coil 161. For example, the aerosol-generating device 100 may control the amplitude and frequency of the alternating current applied to the coil 161.

As an example, the coil 161 may be implemented as a solenoid. The coil 161 may be a solenoid wound along an inner surface of an outer housing of the aerosol-generating device 100, and the heater 160 and aerosol-generating article may be disposed in an interior space of the solenoid. The material forming the wire of the solenoid may include copper (Cu). However, the material is not limited thereto. The materials forming the wires of the solenoid may include: silver (Ag), gold (Au), al, tungsten (W), zinc (Zn), and Ni, or an alloy including at least one of the above-listed materials.

The battery 140 may supply power to the aerosol-generating device 100. The battery 140 may supply power to the coil 161. The battery 140 may include: a battery for supplying a direct current to the aerosol-generating device 100 and a device for converting the supplied direct current from the battery into an alternating current supplied to the coil 161.

The battery 140 may supply a direct current to the aerosol-generating device 100. The battery 140 may be a lithium iron phosphate (LiFePO 4) battery, but is not limited thereto. For example, the battery may be a lithium cobalt oxide (LiCoO 2) battery, a lithium titanate battery, a lithium polymer (li poly) battery, or the like.

The converter may include a low-pass filter that filters a direct current supplied from the battery and outputs an alternating current supplied to the coil 161. The converter may further include an amplifier for amplifying the direct current supplied from the battery. For example, the converter may be implemented using a low pass filter forming a load network for the class D amplifier.

The controller 150 may control the power supplied to the coil 161. The controller 150 may control the battery 140 to adjust the power supplied to the coil 161. For example, the controller 150 may control the temperature at which the heater 160 heats the aerosol-generating article to remain constant in accordance with the temperature of the heater 160.

Next, an example of a cigarette is described with reference to fig. 12 to 14.

Fig. 12 and 13 show examples of cigarettes.

Referring to fig. 12, a cigarette 200 can include a tobacco rod 210 and a filter rod 220. The cigarette 200 may be a heated cigarette that is not combusted but is heated by an aerosol-generating device that includes a heater.

Fig. 12 shows a filter rod 220, the filter rod 220 comprising a single segment. However, the filter rod 220 is not limited thereto. In other words, the filter rod 220 may include a plurality of segments. For example, the filter rod 220 may include: a section configured to cool the aerosol and a section configured to filter a specific component contained in the aerosol. In addition, the filter rod 220 may also include at least one segment configured to perform other functions, as desired.

The diameter of the cigarette 200 may be in the range of about 5mm to about 9mm, and the length of the cigarette 200 may be about 48mm. However, the present disclosure is not limited thereto. For example, the length of the tobacco rod 210 may be about 12mm, the length of the first section of the filter rod 220 may be about 10mm, the length of the second section of the filter rod 220 may be about 14mm, and the length of the third section of the filter rod 220 may be about 12mm. However, the present disclosure is not limited thereto.

Cigarettes 200 may be wrapped with at least one wrapper 240. The wrapper 240 may have at least one hole through which external air may be introduced or internal air may be discharged. For example, cigarettes 200 may be wrapped by a wrapper 240. As another example, cigarettes 200 may be double wrapped with two or more wrappers 240. For example, tobacco rod 210 may be wrapped by first wrapper 241 and filter rod 220 may be wrapped by wrappers 242, 243, and 244. The entire cigarette 200 may be repacked by the fifth wrapper 245. When the filter rod 220 is made up of multiple segments, each segment may be packaged by a separate wrapper 242, 243, and 244.

The first wrapper 241 and the second wrapper 242 may each comprise conventional filter wrap paper. For example, the first wrapper 241 and the second wrapper 242 may each comprise porous wrapping paper or non-porous wrapping paper. In addition, the first wrapper 241 and the second wrapper 242 may each include paper and/or aluminum laminate packaging material having oil resistance.

The third wrapper 243 may comprise a hard wrap paper. For example, the basis weight of third wrapping element 243 may be at about 88g/m ² To about 96g/m ² In particular, the third wrapping element 243 may have a basis weight of about 90g/m ² To about 94g/m ² Within a range of (2). In addition, the thickness of the third wrapping 243 may be in the range of about 120 μm to about 130 μm, and in particular, the thickness of the third wrapping 243 may be 125 μm.

The fourth wrapper 244 may comprise oil resistant hard wrap paper. For example, the basis weight of the fourth wrapper 244 may be about 88g/m ² To about 96g/m ² In particular, the basis weight of the fourth wrapper 244 may be about 90g/m ² To about 94g/m ² Within a range of (2). In addition, the thickness of the fourth wrapper 244 may be in the range of about 120 μm to about 130 μm, and in particular the thickness of the fourth wrapper 244 may be 125 μm.

The fifth wrapper 245 may comprise sterile paper (MFW). Here, MFW refers to specially prepared paper whose tensile strength, water resistance, smoothness, etc. are further improved as compared with plain paper. For example, the fifth wrapper 245 may have a basis weight of about 57g/m ² To about 63g/m ² In particular, the fifth wrapper 245 may have a basis weight of 60g/m ² . In addition, the thickness of the fifth wrapper 245 may be in the range of about 64 μm to about 70 μm, and in particular, the thickness of the fifth wrapper 245 may be 67 μm.

A specific material may be internally added to the fifth wrapper 245. Here, examples of the specific material may include silicon, but are not limited thereto. For example, silicon has characteristics such as heat resistance, oxidation resistance, resistance to various chemicals, water repellency, or electrical insulation, which are small in change with temperature. However, even though the specific material is not silicon, any material having the characteristics described above may be applied to (or coated on) the fifth wrapper 245 without limitation.

The fifth wrapper 245 may prevent the cigarette 200 from burning. For example, when the tobacco rod 210 is heated by the heater, it is likely that the cigarette 200 will burn. Specifically, when the temperature rises above the ignition point of any of the materials included in the tobacco rod 210, the cigarette 200 may burn. Even in this case, since the fifth wrapper 245 includes a non-combustible material, the burning phenomenon of the cigarette 200 can be prevented.

In addition, the fifth wrapper 245 may prevent the aerosol-generating device from being contaminated by substances generated in the cigarette 200. By the user's suction, a liquid substance may be generated in the cigarette 200. For example, when the aerosol generated in the cigarette 200 is cooled by outside air, liquid substances (e.g., moisture, etc.) may be generated. When the fifth wrapper 245 wraps the cigarette 200, liquid substances generated in the cigarette 200 can be prevented from leaking out of the cigarette 200.

The tobacco rod 210 may include an aerosol-generating substance. For example, the aerosol-generating substance may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol, but is not limited thereto. In addition, the tobacco rod 210 may include other additives, such as flavorants, humectants, and/or organic acids. Further, the tobacco rod 210 may include a flavored liquid, such as menthol or a humectant, injected into the tobacco rod 210.

The tobacco rod 210 may be manufactured in various forms. For example, the tobacco rod 210 may be formed as a sheet or filament. Further, the tobacco rod 210 may be formed as a pipe tobacco formed from tiny fragments cut from a sheet of tobacco. Further, the tobacco rod 210 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 210 may uniformly distribute heat transferred to the tobacco rod 210, and thus, may increase the thermal conductivity applied to the tobacco rod 210 and may improve the taste of the tobacco. In addition, the thermally conductive material surrounding the tobacco rod 210 may serve as a base for heating by an induction heater. Here, although not shown in the drawings, the tobacco rod 210 may include an additional base in addition to the thermally conductive material surrounding the tobacco rod 210.

The filter rod 220 may include a cellulose acetate filter. The shape of the filter rod 220 is not limited. For example, the filter rod 220 may include a cylindrical rod or a tube rod having a hollow interior. Further, the filter rod 220 may include a recessed rod. When the filter rod 220 includes a plurality of segments, at least one of the plurality of segments may have a different shape.

The first section of the filter rod 220 may include a cellulose acetate filter. For example, the first section may comprise a tubular structure including a hollow portion therein. When the heater is inserted by the first segment, the internal material of the tobacco rod 210 may be prevented from being pushed back and the cooling effect of the aerosol may be generated. The diameter of the hollow included in the first section may be a suitable diameter in the range of about 2mm to about 4.5mm, but is not limited thereto.

The length of the first segment may be a suitable length in the range of about 4mm to about 30mm, but is not limited thereto. Specifically, the length of the first section may be 10mm, but is not limited thereto.

The hardness of the first stage can be adjusted by adjusting the amount of plasticizer in the manufacture of the first stage. In addition, the first segment may be manufactured by inserting a structure such as a membrane or tube comprising the same material or a different material into the interior of the first segment (e.g., into the hollow).

The second section of the filter rod 220 cools the aerosol generated when the heater heats the tobacco rod 210. Thus, the user can inhale the aerosol cooled to a suitable temperature.

The length or diameter of the second segment may be determined differently depending on the shape of the cigarette 200. For example, the length of the second segment may be suitably determined in the range of about 7mm to about 20 mm. Specifically, the length of the second section may be about 14mm, but is not limited thereto.

The second segment may be manufactured by braiding the polymer fibers. In this case, the flavoured liquid may be applied to fibres made of a polymer. Alternatively, the second segment may be manufactured by braiding together fibers applied with a flavoured liquid and fibers made of a polymer. Alternatively, the second section may be formed from a curled polymeric sheet.

For example, the polymer may comprise a polymer 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 from woven polymer fibers or crimped polymer sheets, the second segment may comprise: a single channel or a plurality of channels extending in the longitudinal direction thereof. Here, a channel refers to a channel through which a gas (e.g., air or aerosol) passes.

For example, the second segment formed from the crimped polymer sheet may be formed from a material having a thickness of 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 section may be about 300mm ² /mm and about 1000mm ² Between/mm. Furthermore, the aerosol-cooling element may be formed from a material having a thickness of between about 10mm ² /mg and about 100mm ² A specific surface area between/mg.

The second segment may comprise a thread containing volatile flavour ingredient. Here, the volatile fragrance ingredient may be menthol, but is not limited thereto. For example, the wire may be filled with a sufficient amount of menthol to provide 1.5mg or more of menthol to the second segment.

The third section of the filter rod 220 may include a cellulose acetate filter. The length of the third section may be suitably determined in the range of about 4mm to about 20 mm. For example, the length of the third section may be about 12mm, but is not limited thereto.

The third segment may be manufactured such that the scent is generated by spraying the flavoured liquid onto the third segment during the manufacturing of the third segment. Alternatively, individual fibers with a flavoured liquid applied may be inserted into the third section. As the aerosol passes through the second section of the filter rod 220, the aerosol generated by the tobacco rod 210 is cooled 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 persistence of the fragrance delivered to the user may be generated.

Further, the filter rod 220 may include at least one bladder 230. Here, the bladder 230 may generate a fragrance or aerosol. For example, the bladder 230 may have a configuration in which a liquid containing a flavoring material is wrapped with a film. For example, the bladder 230 may have a spherical or cylindrical shape, but is not limited thereto.

Referring to fig. 13, cigarette 300 can further include a front end plug 330. The front plug 330 may be located on a side of the tobacco rod 310 opposite the filter rod 320. The front plug 330 may prevent the tobacco rod 310 from escaping outwardly during smoking and prevent liquefied aerosol from flowing from the tobacco rod 310 into the aerosol-generating device.

Referring to fig. 14, the aerosol-generating rod 410, the tobacco rod 420, the cooling rod 430, and the filter rod 440 may be sequentially arranged along the length of the cigarette 400. Here, the longitudinal direction of the cigarette 400 may be a direction in which the length of the cigarette 400 extends. For example, the length direction of the cigarette 400 may be the direction from the aerosol-generating rod 410 toward the filter rod 440. Accordingly, the aerosol generated from at least one of the aerosol-generating rod 410 and the tobacco rod 420 may sequentially pass through the aerosol-generating rod 410, the tobacco rod 420, the cooling rod 430, and the filter rod 440 and form an airflow, and thus the smoker may inhale the aerosol from the filter rod 440.

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 by the microprocessor. Those of ordinary skill in the art will appreciate that a processor may be implemented in other forms of hardware.

The controller 1510 may control the temperature of the heater 1550 by controlling the supply of power from the battery 1540 to the heater 1550. For example, the controller 1510 may control the supply of electric power by controlling the switching of a switching element between the battery 1540 and the heater 1550. In further examples, the direct heating circuit may also control the power to heater 1550 according to control commands of controller 1510.

The controller 1510 may analyze the result sensed by the sensing unit 1520 and control a subsequent process to be performed. For example, the controller 1510 may control power supplied to the heater 1550 to start or end the operation of the heater 1550 based on the result sensed by the sensing unit 1520. As a further example, the controller 1510 may control the amount of power supplied to the heater 1550 and the time of supplying power based on the result sensed by the sensing unit 1520 so that the heater 1550 may be heated to a specific temperature or maintained at an appropriate temperature.

The controller 1510 may control the output unit 1530 based on the result sensed by the sensing unit 1520. For example, when the number of puffs counted by the puff sensor 1526 reaches a preset number, the controller 1510 may notify the user: the aerosol-generating device 1500 will soon terminate with at least one of the display unit 1532, the haptic unit 1534, and the sound output unit 1536.
