In addition, in certain cases, there is a term arbitrarily selected by the applicant, and in this case, the meaning thereof will be described in detail. Therefore, the terms used in the present exemplary embodiments should be defined based on the meanings of the terms and the contents throughout the present exemplary embodiments, rather than simply names of the terms.

Throughout the specification, when a part is connected to another part, this includes not only a case where the part is directly connected, but also a case where the part is electrically connected with another element in between. In addition, when a part includes a certain component, this means that the component may further include other components, not to exclude other components unless specifically stated otherwise. In addition, the term of the components described in the present embodiments means a unit for processing at least one function or operation, which may be implemented in hardware or software, or a combination of hardware and software.

In the present embodiments, "aerosol generating material" means a material capable of generating an aerosol, and may also mean an aerosol-forming substrate. Aerosols can include volatile compounds. The aerosol product may be a solid or a liquid.

For example, solid aerosol generating materials may include solid materials based on tobacco raw materials, such as leaf tobacco, vinegar, reconstituted tobacco, and liquid aerosol generating materials based on nicotine, tobacco extracts and various flavoring agents. It may include a liquid substance. Of course, it is not limited to the above example.

In the present embodiments, the “aerosol generating device” may be a device that generates an aerosol using an aerosol generating material to generate an aerosol that can be directly inhaled into the user's lungs through the user's mouth. For example, the aerosol-generating device may be a holder that can be held by a user.

1 is a view for explaining the use of the aerosol generating device and a cigarette according to an embodiment.

Referring to FIG. 1, the aerosol generating device 1 (hereinafter referred to as a 'holder') may be manufactured in a cylindrical shape, but is not limited thereto. The user can hold and use the holder 1, like a conventional cigarette.

The inside of the holder 1 is provided with a heater 100 that is electrically heated by the power supplied by the battery. The heater 100 is fixed to be located in an empty space (or cavity) 20 formed at one end of the holder 1. The cigarette 3 may be accommodated into the empty space 20 of the holder 1, and when accommodated, the heater 100 may penetrate the inside of the aerosol generating material 21 provided at one end of the cigarette 3. On the other hand, the cigarette 3 may also be used in various terms such as tobacco, tobacco. The cigarette 3 is a smoking article packaged with an aerosol generating material 21 at one end and a filter 22 at the other end, and the aerosol generating material 21 and the filter 22 are wrapped in a wrapper to contact each other. Lost

The aerosol generating material 21 in the cigarette 3 rises in temperature by the heated heater 100, thereby producing an aerosol. The resulting aerosol can be delivered to the user through the filter 22 of the cigarette 3. Here, the heater 100 may heat the aerosol generating material 21 to a temperature at which it does not burn. In other words, the aerosol may be generated from the aerosol generating material 21 by heating the aerosol generating material 21 to a temperature lower than the ignition point of the aerosol generating material 21.

The heater 100 is electrically heated by the power supplied from the battery. The heater 100 shown in FIG. 1 may be in the form of a needle, one end of which is inserted into the aerosol generating material 21 at an acute angle. However, the present invention is not limited thereto, and the heater 100 may be implemented in various forms, such as the tubular heater 100 and the plurality of bead-type heaters 100, and one end of the heater 100 may be curved instead of pointed. It may also be implemented in other forms. That is, if the heater 100 can perform the above-described function, the form may be employed without limitation.

2 is a view for explaining the structure of the heater 100 according to an embodiment.

According to an embodiment, the heater 100 may include a heating unit 215, a first sheet 225 surrounding a portion of the heating unit 215, a second sheet 235 protecting the first sheet 225, and a coating layer. 245 may be included.

According to an embodiment, the heating unit 215 may have a needle-like structure. In addition, the heating part 215 may include a base part and a immersion part. For example, the base of the heating unit 215 may be formed in a cylindrical shape, but is not limited thereto. In addition, the immersion portion of the heating portion 215 may be formed at one end of the base portion to facilitate insertion into the aerosol-forming substrate. At this time, the base and the needle may be formed integrally. Alternatively, the base and the needle may be joined separately after being manufactured separately.

The heating unit 215 may include a thermally conductive material. For example, the thermally conductive material may include ceramics including alumina or zirconia, anodized metals, coated metals, polyimides (PI), and the like. This is not restrictive.

According to an embodiment, the first sheet 225 may cover at least a portion of the heating unit 215. For example, the first sheet 225 may cover at least a portion of the outer circumferential surface of the base of the heater 100. Electrically conductive tracks may be formed in each cross section of the first sheet 225.

In addition, the first electrically conductive tracks formed on one surface of both end surfaces of the first sheet 225 may receive power from the battery. As current flows in the first electrically conductive track, the temperature of the electrically conductive track can rise. In addition, as the temperature of the electrically conductive track rises, heat is transferred to the heating portion 215 adjacent to the electrically conductive track so that the heating portion 215 may be heated.

Depending on the power consumption of the resistance of the first electrically conductive track, the heating temperature of the first electrically conductive track can be determined. Further, based on the power consumption of the resistance of the first electrically conductive track, the resistance value of the first electrically conductive track can be set.

For example, the resistance value of the first electrically conductive track may have a value between 0.5 ohm and 1.2 ohm at 25 degrees Celsius, but is not limited thereto. At this time, the resistance value of the first electrically conductive track can be set by the constituent material, length, width, thickness and pattern of the first electrically conductive track.

According to the resistance temperature coefficient characteristic of the first electrically conductive track, as the temperature increases, the magnitude of the internal resistance may increase. For example, the temperature of the first electrically conductive track and the magnitude of the resistance may be proportional to a predetermined temperature range.

For example, a predetermined voltage is applied to the first electrically conductive track, and the current flowing in the first electrically conductive track can be measured via a current sensor. In addition, the resistance of the first electrically conductive track can be calculated through the ratio of the measured current to the applied voltage. Based on the calculated resistance, according to the resistance temperature coefficient characteristic of the first electrically conductive track, the temperature of the first electrically conductive track or the heating portion 215 may be estimated.

For example, the first electrically conductive track may comprise tungsten, gold, platinum, silver copper, nickel palladium, or a combination thereof. In addition, the first electrically conductive track may be doped with a suitable dopant and may comprise an alloy.

One side or the other side of both sections of the first sheet 225 may include a second electrically conductive track having a resistance temperature coefficient characteristic used to sense the temperature of the heating unit 215. According to the resistance temperature coefficient characteristic of the second electrically conductive track, the magnitude of the internal resistance may increase as the temperature increases. For example, the temperature of the second electrically conductive track and the magnitude of the resistance may be proportional to a predetermined temperature range.

The second electrically conductive track may be disposed adjacent to the heating portion 215. Accordingly, when the temperature of the heating unit 215 increases, the temperature of the adjacent second electrically conductive tracks may also increase. A predetermined voltage is applied to the second electrically conductive track, and the current flowing in the second electrically conductive track can be measured via the current sensor. In addition, the resistance of the second electrically conductive track can be determined through the ratio of the measured current to the applied voltage. Based on the determined resistance, the temperature of the heating portion 215 may be determined according to the resistance temperature coefficient characteristic of the second electrically conductive track.

The resistance value of the second electrically conductive track may vary depending on the temperature of the second electrically conductive track. Thus, based on the change in the resistance value of the second electrically conductive track, the temperature change of the second electrically conductive track can be measured. For example, the resistance value of the second electrically conductive track may have a resistance value between 7 ohms and 18 ohms at 25 degrees Celsius, but is not limited thereto. At this time, the resistance value of the second electrically conductive track may be set by the constituent material, length, width, thickness and pattern of the second electrically conductive track.

For example, the second electrically conductive track may comprise tungsten, gold, platinum, silver copper, nickel palladium, or a combination thereof. In addition, the second electrically conductive track may be doped with a suitable dopant or comprise an alloy.

The first electrically conductive track can be connected with the battery via an electrical connection. As described above, as power is supplied from the battery, the temperature of the first electrically conductive track may increase.

The second electrically conductive track can include an electrical connection to which a direct current (DC) voltage is applied. The electrical connection of the second electrically conductive track is separated from the electrical connection of the first electrically conductive track. In addition, when the DC voltage applied to the second electrically conductive track is constant, the magnitude of the current flowing in the second electrically conductive track can be determined based on the resistance of the second electrically conductive track.

The second electrically conductive track may be connected with an OP Amp. The OP Amp receives a signal based on an externally powered power supply, an input electrically connected to a second electrically conductive track and receiving a DC voltage and / or current, and a DC voltage and / or current applied to the input. It may include an output unit for outputting.

The OP Amp may receive a DC voltage through the power supply. In addition, the OP Amp may receive a DC voltage through the input unit. At this time, the magnitude of the DC voltage applied through the input of the OP Amp and the magnitude of the DC voltage applied through the power supply of the OP Amp may be the same. In addition, the DC voltage applied to the input of the OP Amp may be the same as the DC voltage applied to the electrical connection of the second electrically conductive track.

The electrical connection of the second electrically conductive track and the input of the OP Amp can be separated from the electrical connection of the first electrically conductive track.

As the temperature of the second electrically conductive track changes, the resistance value of the second electrically conductive track may change. Thus, the second electrically conductive track functions as a variable resistor having temperature as a control variable, and as the resistance value of the second electrically conductive track changes, the second electrically conductive track is introduced into the input portion of the OP Amp electrically connected to the second electrically conductive track. Current changes As the resistance value of the second electrically conductive track increases, the current flowing into the input of the OP Amp electrically connected with the second electrically conductive track decreases. At this time, even if the resistance value of the second electrically conductive track is changed, the DC voltage applied to the input portion of the OP Amp may be constant.

As the current flowing into the input of the OP Amp changes, the voltage and / or current of the signal output from the output of the OP Amp may change. For example, as the input current of OP Amp increases, the output voltage of OP Amp may increase. As another example, the output voltage of the OP Amp may decrease as the input current of the OP Amp increases.

Further, when a constant DC voltage is applied to the input of the OP Amp, the relationship between the temperature of the second electrically conductive track and the resistance value, the relationship between the resistance value of the second electrically conductive track and the input current applied to the OP Amp, and the OP Amp The relationship between the input current and the output voltage can be obtained experimentally or set experimentally. Thus, by measuring the change in the output voltage and / or output voltage of the OP Amp, it is possible to sense the temperature and / or the change in temperature of the second electrically conductive track.

For example, OP Amp may have a characteristic that the voltage of the output of the OP Amp increases as the input current flowing into the input increases. In this case, the temperature of the heater increases as power is supplied to the first electrically conductive tracks. As a result, the temperature of the second electrically conductive track increases. At this time, due to an increase in the resistance of the second electrically conductive track, the magnitude of the input current applied to the input of the OP Amp may decrease. Thus, the voltage at the output of the OP Amp is reduced. Conversely, as the power supply to the first electrically conductive track is cut off or the power supply of the first electrically conductive track is reduced, the voltage of the output of the OP Amp increases as the temperature of the heater decreases.

As another example, OP Amp may have a characteristic that the voltage of the output decreases as the input current flowing into the input increases. In this case, the temperature of the heater increases as power is supplied to the first electrically conductive tracks. As a result, the temperature of the second electrically conductive track increases. At this time, due to an increase in the resistance of the second electrically conductive track, the magnitude of the input current applied to the input of the OP Amp may decrease. Thus, the voltage at the output of the OP Amp increases. Conversely, as the power supply to the first electrically conductive track is cut off or the power supply of the first electrically conductive track is reduced, the voltage of the output of the OP Amp decreases as the temperature of the heater decreases.

The output of the OP Amp may be connected to the processor. For example, the processor may be a micro controller unit (MCU). The processor may sense the temperature of the second electrically conductive track or heating based on the output voltage of the OP Amp. In addition, the processor may adjust the supply voltage supplied to the first electrically conductive track based on the temperature of the heating portion.

According to one embodiment, the first electrically conductive tracks and the second electrically conductive tracks may be formed in each of both cross-sections of the first sheet 225. For example, the first electrically conductive track may be included on one surface of the first sheet 225 in contact with the heating unit 215 of both cross sections, and the second electrically conductive track may be included on the other surface of the first sheet 225. As another example, the second electrically conductive track may be included on one surface of the first sheet 225 in contact with the heating unit 215, and the first electrically conductive track may be included on the other surface of the first sheet 225.

According to another embodiment of the present disclosure, the first electrically conductive track and the second electrically conductive track may be included in the same side of both cross-sections of the first sheet 225. For example, the first electrically conductive track and the second electrically conductive track may be included in one surface of the first sheet 225 in contact with the heating unit 215. As another example, the first electrically conductive track and the second electrically conductive track may be included on one surface of the first sheet 225 not in contact with the heating unit 215.

For example, the first sheet 225 may be a green sheet made of a ceramic composite material. In this case, the ceramic may include a compound such as alumina, zirconia, but is not limited thereto.

According to an embodiment, the second sheet 235 may cover at least a portion of the first sheet 225. In addition, the second sheet 235 may have rigidity.

Thus, the second sheet 235 protects the first sheet 225 and the electrically conductive tracks when the heater 100 is inserted into the aerosol forming substrate.

For example, the second sheet 235 may be a green sheet configured as a ceramic composite material. In this case, the ceramic may include a compound such as alumina, zirconia, but is not limited thereto.

The second sheet 235 may be coated with a glaze to facilitate insertion of the heater 100 into the cigarette 3 and to improve durability of the heater 100. As the second sheet 235 is coated with a glaze, the rigidity of the second sheet 235 may increase.

Each of the heating unit 215, the first sheet 225, and the second sheet 235 may be selectively manufactured from the same material group, for example, a ceramic that is a compound such as alumina or zirconia.

Further, each of the first electrically conductive track and the second electrically conductive track may be selectively manufactured from the same material group, for example, tungsten, gold, platinum, silver copper, nickel palladium, a combination thereof, or the like. At this time, even if the constituent material of the first electrically conductive track and the constituent material of the second electrically conductive track are the same, the resistance values of the first electrically conductive track and the second electrically conductive track are determined by the length, width, or pattern of the track. Due to differences, they may be different.

According to an embodiment, the first electrically conductive track for heating the heating unit 215 may be included in the heating unit 215, the first sheet 225, or the second sheet 235. Alternatively, a plurality of electrically conductive tracks for heating the heating part 215, such as the first electrically conductive track, may be included in at least one of the heating part 215, the first sheet 225, and the second sheet 235. have.

And the same portion of the second sheet 235, respectively. Alternatively, the first electrically conductive track for heating the heating unit 215 and the second electrically conductive track for sensing the temperature of the heating unit 215 may include the heating unit 215, the first sheet 225, and the second sheet. 235 may be included in different portions.

As the coating layer 245 is provided on the heater 100 according to an embodiment, the stair surface formed by the laminated structure including the heating unit 215, the first sheet 225, and the second sheet 235. (stepped surface) can be flattened. For example, the stair plane 255 is formed because the edges of the first sheet 225 and the edges of the second sheet 235 do not coincide or because of the thickness of the first sheet 225 and the second sheet 235. Can be. For example, due to the step plane 255, friction may increase when the heater 100 is inserted into the aerosol-forming substrate. In addition, deposits or residues generated from the aerosol-forming substrate may be contaminated in the stepped plane 255 to contaminate the heater 100, thereby reducing the performance of the heater 100, such as reducing the thermal conductivity of the heater 100. Can be. Therefore, in order to planarize the stair plane 255, the coating layer 245 may be formed on the outer surface of the heater 100.

The outer surface of the heater 100 formed of the coating layer 245 may include an immersion portion of the coating layer 245 corresponding to the immersion portion of the heating portion 215, a base portion of the heating portion 215, a first sheet 225, and a first portion. It may include a base of the coating layer 245 corresponding to the two sheets 235.

In addition, the coating layer 245 may include a composite coating layer composed of a combination of two or more of a glass film coating layer, a Teflon coating layer, and a thermomol coating layer, but is not limited thereto.

FIG. 3 is a diagram for describing a staircase plan 255 of FIG. 2, according to an exemplary embodiment.

In FIG. 3, a step plane (255 of FIG. 2) of the first sheet 225 and the second sheet 235 may be formed to surround the base and the base of the heater.

For example, a terrace 221 may be formed by the thickness of the first sheet 225. In addition, the terrace 231 may be formed by the thickness of the second sheet 235.

In addition, a step 211 may be formed because the boundary between the immersion portion of the heating table and the base portion and the edge of the first sheet 225 do not coincide. In addition, since the edge of the first sheet 225 and the edge of the second sheet 235 do not coincide with each other, the step 222 may be formed.

The first electrically conductive track 320 may heat the heating unit 215 of the heater 100 as a current flows therein. The electrically conductive track can be connected to an external power source via a connection. In addition, as power is supplied to the electrically conductive track from an external power source, current may flow inside the electrically conductive track. As a result, the electrically conductive tracks generate heat, thereby transferring heat to the adjacent heating portion 215 of FIG. 2, thereby heating the heating portion 215 of FIG. 2.

The second surface 330 of the first sheet 225 may include a second electrically conductive track 340 having a resistance temperature coefficient characteristic used to sense the temperature of the heating portion 215 of FIG. 2. As described above, according to the resistance temperature coefficient characteristic of the second electrically conductive track 340, the size of the internal resistance may increase as the temperature increases. For example, the temperature of the second electrically conductive track 340 and the magnitude of the resistance may be proportional to each other at a constant temperature range.

The second electrically conductive track 340 may be disposed adjacent to the heating portion 215 of FIG. 2. For example, as the heating unit 215 is heated, heat may be transferred from the heating unit 215 to the second electrically conductive track 340. When the temperature of the heating unit 215 increases, the temperature of the second electrically conductive track 340 may also increase, and the resistance of the second electrically conductive track 340 may increase. On the contrary, when the temperature of the heating unit 215 decreases, as the temperature of the second electrically conductive track 340 decreases, the resistance of the second electrically conductive track 340 may decrease.

The second electrically conductive track 340 may be connected to a controller (not shown) through a connection. For example, the second electrically conductive track 340 may be connected to a processor for controlling the temperature of the heating unit 215 of FIG. 2, for example, the second electrically conductive track 340 is connected to a controller (not shown). . Using the relationship between the resistance of the second electrically conductive track 340 and the temperature, the resistance of the second electrically conductive track 340 is determined from the voltage and current of the second electrically conductive track 340, and the heating portion from the determined resistance. The temperature of 215 can be determined. Based on the temperature determined using the second electrically conductive track 340, the power supplied to the first electrically conductive track 320 can be adjusted.

Referring to FIG. 5, the system 500 may include a heater 100, a battery 510, and a controller 520. Since the heater 100 corresponds to the heater 100 of FIG. 2, the description of the heater 100 will be replaced with the above description in FIG. 2.

The battery 510 may be connected to the heater 100 through the first connector 530. For example, the battery 510 may be electrically connected to the first electrically conductive track of the first sheet of the heater 100 to supply power to the first electrically conductive track.

The controller 520 may adjust the power supplied from the battery 510 to the heater 100 based on the determination that the temperature of the heater 100 is adjusted. For example, the controller 520 may adjust the magnitude or period of the pulse voltage supplied from the battery 510 to the heater 100.

The controller 510 according to an embodiment may include an OP Amp.

The second electrically conductive track can be connected to the OP Amp through the second connector 540. The OP Amp is an electrical signal based on an externally powered power supply, an input electrically connected to a second electrically conductive track and receiving a DC voltage and / or current, and a DC voltage and / or current applied to the input. It may include an output unit for outputting.

The OP Amp may receive a DC voltage through the power supply. In addition, the OP Amp may receive a DC voltage through the input unit. At this time, the magnitude of the DC voltage applied through the input of the OP Amp and the magnitude of the DC voltage applied through the power supply of the OP Amp may be the same. In addition, the DC voltage applied to the input of the OP Amp may be the same as the DC voltage applied to the second connector 540 of the second electrically conductive track.

The second connector 540 of the second electrically conductive track and the input of the OP Amp may be separated from the first connector 530 of the first electrically conductive track.

As the temperature of the second electrically conductive track changes, the resistance value of the second electrically conductive track may change. Thus, the second electrically conductive track functions as a variable resistor having temperature as a control variable, and as the resistance value of the second electrically conductive track changes, the second electrically conductive track is introduced into the input portion of the OP Amp electrically connected to the second electrically conductive track. Current changes As the resistance value of the second electrically conductive track increases, the current flowing into the input of the OP Amp electrically connected with the second electrically conductive track decreases. At this time, even if the resistance value of the second electrically conductive track is changed, the DC voltage applied to the input portion of the OP Amp may be constant.

As the current flowing into the input of the OP Amp changes, the voltage and / or current of the signal output from the output of the OP Amp may change. For example, as the input current of OP Amp increases, the output voltage of OP Amp may increase. As another example, the output voltage of the OP Amp may decrease as the input current of the OP Amp increases.

Further, when a constant DC voltage is applied to the input of the OP Amp, the relationship between the temperature of the second electrically conductive track and the resistance value, the relationship between the resistance value of the second electrically conductive track and the input current applied to the OP Amp, and the OP Amp The relationship between the input current and the output voltage can be obtained experimentally or set experimentally. Thus, by measuring the change in the output voltage and / or output voltage of the OP Amp, it is possible to sense the temperature and / or the change in temperature of the second electrically conductive track.

For example, OP Amp may have a characteristic that the voltage of the output of the OP Amp increases as the input current flowing into the input increases. In this case, the temperature of the heater increases as power is supplied to the first electrically conductive tracks. As a result, the temperature of the second electrically conductive track increases. At this time, due to an increase in the resistance of the second electrically conductive track, the magnitude of the input current applied to the input of the OP Amp may decrease. Thus, the voltage at the output of the OP Amp is reduced. Conversely, as the power supply to the first electrically conductive track is cut off or the power supply of the first electrically conductive track is reduced, the voltage of the output of the OP Amp increases as the temperature of the heater decreases.

As another example, OP Amp may have a characteristic that the voltage of the output decreases as the input current flowing into the input increases. In this case, the temperature of the heater increases as power is supplied to the first electrically conductive tracks. As a result, the temperature of the second electrically conductive track increases. At this time, due to an increase in the resistance of the second electrically conductive track, the magnitude of the input current applied to the input of the OP Amp may decrease. Thus, the voltage at the output of the OP Amp increases. Conversely, as the power supply to the first electrically conductive track is cut off or the power supply of the first electrically conductive track is reduced, the voltage of the output of the OP Amp decreases as the temperature of the heater decreases.

The output of the OP Amp may be connected to the processor. The processor may be, for example, an MCU. The processor may sense the temperature of the second electrically conductive track or heating based on the output voltage of the OP Amp. In addition, the processor may adjust the supply voltage supplied to the first electrically conductive track based on the temperature of the heating portion.

6 is a configuration diagram illustrating an example of an aerosol generating device.

Referring to FIG. 6, the holder 1 includes a battery 110, a controller 120, and a heater 2130. In addition, the holder 1 includes an inner space formed by the case 2140. A cigarette may be inserted into the inner space of the holder 1.

In the holder 1 shown in FIG. 6, only the components related to this embodiment are shown. Accordingly, it will be understood by those skilled in the art that the general purpose components other than the components shown in FIG. 6 may be further included in the holder 1.

When the cigarette is inserted into the holder 1, the holder 1 heats the heater 2130. The aerosol generating material in the cigarette is raised in temperature by the heated heater 2130, thereby producing an aerosol. The resulting aerosol is delivered to the user through the filter of the cigarette. However, even when a cigarette is not inserted into the holder 1, the holder 1 may heat the heater 2130.

The case 2140 may be separated from the holder 1. For example, the case 2140 can be detached from the holder 1 by the user turning the case 2140 clockwise or counterclockwise.

In addition, the diameter of the hole formed by the end 2141 of the case 2140 may be made smaller than the diameter of the space formed by the case 2140 and the heater 2130, in which case it is inserted into the holder 1 Can serve as a guide to cigarettes.

The battery 110 supplies the power used to operate the holder 1. For example, the battery 110 may supply power so that the heater 2130 may be heated, and may supply power necessary for the control unit 120 to operate. In addition, the battery 110 may supply power required to operate a display, a sensor, a motor, and the like installed in the holder 1.

The battery 110 may be a lithium iron phosphate (LiFePO 4) battery, but is not limited to the example described above. For example, the battery 110 may correspond to a lithium cobalt oxide (LiCoO 2) battery, a lithium titanate battery, or the like.

In addition, the battery 110 may have a cylindrical shape having a diameter of 10 mm and a length of 37 mm, but is not limited thereto. The capacity of the battery 110 may be 120 mAh or more, and may be a rechargeable battery or a disposable battery. For example, when the battery 110 can be charged, the charge rate (C-rate) of the battery 110 may be 10C, the discharge rate (C-rate) may be 16C to 20C, but is not limited thereto. In addition, for stable use, the battery 110 may be manufactured so that more than 80% of the total capacity may be secured even when charging / discharging is performed 8000 times.

Here, whether the battery 110 is fully charged or completely discharged may be determined by how much the power stored in the battery 110 is compared with the total capacity of the battery 110. For example, when the power stored in the battery 110 is 95% or more of the total capacity, it may be determined that the battery 110 is fully charged. In addition, when the power stored in the battery 110 is 10% or less of the total capacity, it may be determined that the battery 110 is completely discharged. However, the criterion for determining whether the battery 110 is fully charged or completely discharged is not limited to the above-described example.

The heater 2130 is heated by the power supplied from the battery 110. When the cigarette is inserted into the holder 1, the heater 2130 is located inside the cigarette. Thus, the heated heater 2130 may raise the temperature of the aerosol generating material in the cigarette.

The heater 2130 may have a shape in which a cylinder and a cone are combined. For example, the heater 2130 may have a cylindrical shape having a diameter of about 2 mm and a length of about 23 mm, and the end 2131 of the heater 2130 may be finished at an acute angle, but is not limited thereto. In other words, the heater 2130 may be applied without limitation as long as the heater 2130 may be inserted into the cigarette. In addition, only a part of the heater 2130 may be heated. For example, assuming that the length of the heater 2130 is 23 mm, only 12 mm from the end 2131 of the heater 2130 may be heated, and the remaining portion of the heater 2130 may not be heated.

The heater 2130 may be an electrically resistive heater. For example, the heater 2130 may include an electrically conductive track, and the heater 2130 may be heated as a current flows in the electrically conductive track.

For stable use, the heater 2130 may be supplied with power in accordance with the specifications of 3.2 V, 2.4 A, 8 W, but is not limited thereto. For example, when electric power is supplied to the heater 2130, the surface temperature of the heater 2130 may rise to 400 ° C. or more. The surface temperature of the heater 2130 may rise to about 350 ° C. before exceeding 15 seconds from when power is supplied to the heater 2130.

Holder 1 may be provided with a separate temperature sensor. Alternatively, the temperature sensor may not be provided in the holder 1, and the heater 2130 may serve as a temperature sensor. For example, the heater 2130 may further include a second electrically conductive track for temperature sensing in addition to the first electrically conductive track for heat generation.

For example, if the voltage across the second electrically conductive track and the current flowing through the second electrically conductive track are measured, the resistance R can be determined. At this time, the temperature T of the second electrically conductive track may be determined by Equation 1 below.

In Equation 1, R means the current resistance value of the second electrically conductive track, R0 means the resistance value at the temperature T0 (eg 0 ° C.), and α is the resistance temperature of the second electrically conductive track. Means coefficient. The conductive material (eg metal) has a unique resistance temperature coefficient, so α may be predetermined according to the conductive material constituting the second electrically conductive track. Therefore, when the resistance R of the second electrically conductive track is determined, the temperature T of the second electrically conductive track can be calculated by Equation 1 above.

Heater 2130 may be comprised of at least one electrically conductive track (a first electrically conductive track and a second electrically conductive track). For example, the heater 2130 may be composed of two first electrically conductive tracks and one or two second electrically conductive tracks, but is not limited thereto.

The electrically conductive track comprises an electrically resistive material. As one example, the electrically conductive track can be made of a metallic material. As another example, the electrically conductive track can be made of an electrically conductive ceramic material, carbon, a metal alloy or a composite of ceramic material and metal.

In addition, the holder 1 may include both an electrically conductive track and a temperature sensing sensor serving as a temperature sensing sensor.

The controller 120 may control the amount of power supplied to the heater 2130 and the time at which power is supplied so that the heater 2130 may be heated to a predetermined temperature or maintain an appropriate temperature. In addition, the controller 120 may check the state of the battery 110 (for example, the remaining amount of the battery 110) and generate a notification signal if necessary.

In addition, the controller 120 may check the presence or absence of the puff and the strength of the puff, and count the number of puffs. In addition, the controller 120 may continuously check the time that the holder 1 is operating. In addition, the controller 120 determines whether the cradle 2 to be described later is coupled with the holder 1, and controls the operation of the holder 1 according to the coupling or detachment of the cradle 2 and the holder 1.

In addition, when the holder 1 and the cradle 2 are coupled, the battery 210 may supply power used to operate the holder 1. For example, when the terminal 2170 of the holder 1 and the terminal 2260 of the cradle 2 are coupled, regardless of whether or not the battery 110 of the holder 1 is discharged, the holder 1 is the cradle. It can operate using the power supplied by the battery 210 of (2).

An example of the type of the battery 210 may be the same as the example of the battery 110 described above with reference to FIG. 6. The capacity of the battery 210 may be greater than that of the battery 110, for example, the capacity of the battery 210 may be 3000 mAh or more, but the capacity of the battery 210 is not limited to the above-described example. Do not.

The controller 220 generally controls the operation of the cradle 2. The controller 220 may control the operation of all the components of the cradle 2. In addition, the controller 220 may determine whether the holder 1 and the cradle 2 are coupled, and control the operation of the cradle 2 according to the coupling or detachment of the cradle 2 and the holder 1.

9A and 9B illustrate an example of a cradle from various aspects.

9A is a diagram illustrating an example of the cradle 2 viewed from the first direction. One side of the cradle 2 has a space 2230 into which the holder 1 can be inserted. Further, even if the cradle 2 does not include a separate fixing means such as a lid, the holder 1 can be inserted into and secured to the cradle 2. In addition, the cradle 2 may include a button 2240 for allowing a user to control the cradle 2 and a display 2250 for outputting an image.

9B is a view showing an example of the cradle 2 viewed from the second direction. The cradle 2 may include a terminal 2260 coupled with the holder 1 inserted therein. Since the terminal 2260 is coupled to the terminal 2170 of the holder 1, the battery 110 of the holder 1 may be charged by the power supplied by the battery 210 of the cradle 2. In addition, the holder 1 may be operated by the power supplied from the battery 210 of the cradle 2 through the terminal 2170 and the terminal 2260, and a signal between the holder 1 and the cradle 2 may be used. Transmission and reception of is possible. For example, the terminal 2260 may be composed of four micro pins, but is not limited thereto.

As described above, the holder 1 may be inserted into the interior space 2230 of the cradle 2. In addition, the holder 1 may be fully inserted into the cradle 2 or may be tilted in the state of being inserted into the cradle 2. Hereinafter, examples in which the holder 1 is inserted into the cradle 2 will be described.

10 is a diagram illustrating an example in which a holder is inserted into a cradle.

Referring to FIG. 10, an example in which the holder 1 is inserted into the cradle 2 is illustrated. Since the space 2230 into which the holder 1 is to be inserted exists on one side of the cradle 2, the inserted holder 1 may not be exposed to the outside by the other sides of the cradle 2. Thus, the cradle 2 may not include another configuration (eg a lid) for not exposing the holder 1 to the outside.

The cradle 2 may include at least one fastening member 2251, 2272 to increase the fastening strength with the holder 1. In addition, the holder 1 may also include at least one fastening member 2181. Here, the binding members 2181, 2271, and 2272 may be magnets, but are not limited thereto. In FIG. 10, for convenience of description, although the holder 1 includes one fastening member 2181 and the cradle 2 includes two fastening members 2231 and 2272, the fastening member The number of (2181, 2271, 2272) is not limited to this.

The holder 1 may include a fastening member 2181 in a first position, and the cradle 2 may include fastening members 2251 and 2272 in a second position and a third position, respectively. In this case, the first position and the third position may be positions facing each other when the holder 1 is inserted into the cradle 2.

As the holder 1 and the cradle 2 include the fastening members 2181, 2271, 2272, even if the holder 1 is inserted into one side of the cradle 2, the holder 1 and the cradle 2 are held in place. It can bind more strongly. In other words, as the holder 1 and the cradle 2 further include the fastening members 2181, 2271 and 2272 in addition to the terminals 2170 and 2260, the holder 1 and the cradle 2 may be more strongly bound. have. Thus, even if the cradle 2 does not have a separate configuration (eg a lid), the inserted holder 1 may not be easily separated from the cradle 2.

In addition, when it is determined that the holder 1 is completely inserted into the cradle 2 by the terminals 2170 and 2260 and / or the fastening members 2181, 2271 and 2272, the controller 220 may determine that the battery 210 is connected to the battery 210. The battery 110 of the holder 1 may be charged using electric power.

11 is a diagram illustrating an example in which the holder is tilted in a state where the holder is inserted into the cradle.

Referring to FIG. 11, the holder 1 is tilted inside the cradle 2. Here, tilt means that the holder 1 is inclined at an angle with the holder 1 inserted in the cradle 2.

As shown in FIG. 10, when the holder 1 is fully inserted into the cradle 2, the user cannot smoke. In other words, when the holder 1 is fully inserted into the cradle 2, no cigarette can be inserted into the holder 1. Thus, the user cannot smoke while the holder 1 is fully inserted into the cradle 2.

As shown in FIG. 11, when the holder 1 is tilted, the end 2141 of the holder 1 is exposed to the outside. Thus, the user can insert a cigarette at the end 2141 and inhale (smoke) the resulting aerosol. The tilt angle [theta] can be secured at an angle sufficient to prevent the cigarette from being bent or damaged when the cigarette is inserted into the end 2141 of the holder 1. For example, the holder 1 may be tilted as much as the entire cigarette insertion hole included in the distal end 2141 may be exposed to the outside. For example, the range of the tilt angle θ may be greater than 0 ° and less than or equal to 180 °, and preferably, greater than or equal to 10 ° and less than or equal to 90 °. More preferably, the range of the tilt angle θ is 10 ° or more and 20 ° or less, 10 ° or more and 30 ° or less, 10 ° or more and 40 ° or less, 10 ° or more and 50 ° or less, or 10 ° or more and 60 ° or less. Can be.

In addition, even when the holder 1 is tilted, the terminal 2170 of the holder 1 and the terminal 2260 of the cradle 2 are coupled to each other. Accordingly, the heater 2130 of the holder 1 may be heated by the power supplied by the battery 210 of the cradle 2. Thus, even when the remaining amount of battery 110 in holder 1 is low or absent, holder 1 may generate aerosol using battery 210 of cradle 2.

11 shows an example in which the holder 1 comprises one fastening member 2182 and the cradle 2 includes two fastening members 2273, 2274. For example, the positions of each of the binding members 2182, 2273, and 2274 are as described above with reference to FIG. 10. If the binding members 2182, 2273, and 2274 are magnets, the magnet strength of the binding member 2274 may be greater than the magnet strength of the binding member 2273. Thus, even when the holder 1 is tilted, by the binding member 182 and the binding member 2274, the holder 1 may not be completely separated from the cradle 2.

In addition, when it is determined that the holder 1 is tilted by the terminals 2170, 2260 and / or the binding members 2182, 2273, and 2274, the controller 220 uses the power of the battery 210 to control the holder. The heater 2130 of (1) may be heated or the battery 110 may be charged.

12A-12B illustrate examples in which a holder is inserted into a cradle.

12A shows an example in which the holder 1 is fully inserted into the cradle 2. When the holder 1 is fully inserted into the cradle 2, the inner space 2230 of the cradle 2 may be sufficiently secured to minimize the user contact with the holder 1. When the holder 1 is fully inserted into the cradle 2, the controller 220 supplies power of the battery 210 to the holder 1 so that the battery 110 of the holder 1 can be charged.

12B shows an example in which the holder 1 is tilted with the cradle 2 inserted. When the holder 1 is tilted, the control unit 220 supplies power of the battery 210 so that the battery 110 of the holder 1 may be charged or the heater 2130 of the holder 1 may be heated. It supplies to (1).

13 is a flowchart for explaining an example in which the holder and the cradle operate.

The method of producing the aerosol shown in FIG. 13 consists of the steps processed in time series in the holder 1 shown in FIG. 6 or the cradle 2 shown in FIG. 8. Therefore, even if omitted below, it can be seen that the contents described above with respect to the holder 1 shown in FIG. 6 and the cradle 2 shown in FIG. 8 also apply to the method of FIG. 13.

In operation 2710, the holder 1 determines whether it is inserted into the cradle 2. For example, the controller 120 may determine whether the holder 1 and the cradle 2 have terminals 2170 and 2260 connected to each other and / or that the binding members 2181, 2271 and 2272 operate. It may be determined whether 1) is inserted into the cradle 2.

When the holder 1 is inserted into the cradle 2, the process proceeds to step 2720, and when the holder 1 has the cradle 2 separated, the process proceeds to step 2730.

In operation 2720, the cradle 2 determines whether the holder 1 is tilted. For example, the controller 220 may determine whether the holder 1 and the cradle 2 have terminals 2170 and 2260 connected to each other and / or whether the binding members 2182, 2273 and 2274 operate. It is possible to determine whether 1) is tilted.

In operation 2720, the cradle 2 determines whether the holder 1 is tilted, but the present invention is not limited thereto. In other words, whether the holder 1 is tilted may be determined by the controller 120 of the holder 1.

When the holder 1 is tilted, the process proceeds to step 2740, and when the holder 1 is not tilted (that is, when the holder 1 is fully inserted into the cradle 2), the process proceeds to step 2770.

In operation 2730, the holder 1 determines whether the use condition of the holder 1 is satisfied. For example, the controller 120 may determine whether the use condition is satisfied by checking whether the remaining amount of the battery 110 and other components of the holder 1 can operate normally.

If the use condition of the holder 1 is satisfied, the process proceeds to step 2740, otherwise, the procedure ends.

In step 2740, the holder 1 informs the user that it is available. For example, the controller 120 may output an image indicating that it is available for the display of the holder 1 or generate a vibration signal by controlling a motor of the holder 1.

In step 2750, the heater 2130 is heated. As an example, when the holder 1 is separated from the cradle 2, the heater 2130 may be heated by the power of the battery 110 of the holder 1. As another example, when the holder 1 is tilted, the heater 2130 may be heated by the power of the battery 210 of the cradle 2.

The controller 120 of the holder 1 or the controller 220 of the cradle 2 checks the temperature of the heater 2130 in real time to supply the amount of power supplied to the heater 2130 and the power to the heater 2130. You can adjust the time. For example, the controllers 120 and 220 may check the temperature of the heater 2130 in real time through a temperature sensing sensor included in the holder 1 or an electrically conductive track of the heater 2130.

In step 2760, the holder 1 performs an aerosol generating mechanism. For example, the controllers 120 and 220 check the temperature of the heater 2130 that changes as the user performs a puff to adjust the amount of power supplied to the heater 2130 or to supply power to the heater 2130. You can stop. In addition, the controllers 120 and 220 may count the number of puffs of the user, and may output information indicating that the holder needs cleaning when a certain number of puffs (for example, 1500 times) is reached.

In step 2770, the cradle 2 performs charging of the holder 1. For example, the controller 220 may charge the holder 1 by supplying power of the battery 210 of the cradle 2 to the battery 110 of the holder 1.

Meanwhile, the controllers 120 and 220 may stop the operation of the holder 1 according to the number of puffs of the user or the operation time of the holder 1. Hereinafter, an example in which the control unit 120 or 220 stops the operation of the holder 1 will be described with reference to FIG. 14.

14 is a flowchart for explaining another example in which the holder operates.

The method of producing the aerosol shown in FIG. 14 consists of the steps processed in time series in the holder 1 shown in FIG. 6 and the cradle 2 shown in FIG. 8. Therefore, even if omitted below, it can be seen that the above descriptions regarding the holder 1 shown in FIG. 6 or the cradle 2 shown in FIG. 8 also apply to the method of FIG. 14.

In operation 2810, the controller 120 or 220 determines whether the user is puffed. For example, the controllers 120 and 220 may determine whether the user puffs through the puff detection sensor included in the holder 1.

In operation 2820, an aerosol is generated according to the puff of the user. The controllers 120 and 220 may adjust the power supplied to the heater 2130 according to the temperature of the user's puff and the heater 2130 as described above with reference to FIG. 13. Also, the controllers 120 and 220 count the number of puffs of the user.

In operation 2830, the controller 120 or 220 determines whether the number of puffs of the user is greater than or equal to the number of puffs. For example, assuming that the number of puffs is set to 14 times, the controllers 120 and 220 determine whether the counted number of puffs is 14 or more times.

Meanwhile, when the number of puffs of the user is close to the number of puffs (for example, when the number of puffs of the user is 12 times), the controllers 120 and 220 may output a warning signal through a display or a vibration motor.

If the number of puffs of the user is greater than or equal to the puff limit, the process proceeds to step 2850. If the number of puffs of the user is less than the limit of the puff, the process proceeds to step 2840.

In operation 2840, the controller 120 or 220 determines whether the time when the holder 1 is operated is greater than or equal to the operation time limit. Herein, the time when the holder 1 is operated means the time accumulated from the time when the holder starts operation to the present time. For example, assuming that the operation time limit is set to 10 minutes, the controllers 120 and 220 determine whether the holder 1 is operating for 10 minutes or more.

On the other hand, when the operation time of the holder 1 is close to the operation time limit (for example, when the holder 1 is operating for 8 minutes), the controllers 120 and 220 control the warning signal through the display or the vibration motor. You can output

If the holder 1 is operating longer than the operation time limit, the process proceeds to step 2850. If the holder 1 has an operation time less than the operation time limit, the process proceeds to step 2820.

In operation 2850, the controllers 120 and 220 forcibly terminate the operation of the holder. In other words, the controllers 120 and 220 stop the aerosol generation mechanism of the holder. For example, the controllers 120 and 220 may forcibly terminate the operation of the holder by cutting off the power supplied to the heater 2130.

15 is a flowchart for explaining an example in which the cradle operates.

The flowchart shown in FIG. 15 consists of steps that are processed in time series in the cradle 2 shown in FIG. Therefore, even if omitted below, it can be seen that the above description of the cradle 2 shown in FIG. 8 also applies to the flowchart of FIG. 15.

Although not shown in FIG. 15, the operation of the cradle 2 to be described below may be performed regardless of whether the holder 1 is inserted into the cradle 2.

In operation 2910, the control unit 220 of the cradle 2 determines whether the button 2240 is pressed. If the button 2240 is pressed, the process proceeds to step 2920, and if the button 2240 is not pressed, the process proceeds to step 2930.

In step 2920, the cradle 2 displays the state of the battery. For example, the controller 220 may output information on the current state (eg, remaining amount) of the battery 210 to the display 2250.

In operation 2930, the controller 220 of the cradle 2 determines whether a cable is connected to the cradle 2. For example, the controller 220 determines whether a cable is connected to an interface (eg, a USB port) included in the cradle 2. If the cable is connected to the cradle (2), the process proceeds to step 2940, otherwise the procedure is terminated.

In operation 2940, the cradle 2 performs a charging operation. For example, the cradle 2 charges the battery 210 using power supplied through the connected cable.

As described above, a cigarette may be inserted into the holder 1. The cigarette comprises an aerosol generating material and an aerosol is produced by the heated heater 2130.

Hereinafter, with reference to FIGS. 16-18F, the example of the cigarette which can be inserted in the holder 1 is demonstrated.

16 is a view illustrating an example in which a cigarette is inserted into a holder.

Referring to FIG. 16, the cigarette 3 may be inserted into the holder 1 through the end 2141 of the case 2140. When the cigarette 3 is inserted, the heater 2130 is located inside the cigarette 3. Accordingly, the aerosol generating material of the cigarette 3 is heated by the heated heater 2130, thereby producing an aerosol.

The cigarette 3 may be similar to a general combustion cigarette. For example, the cigarette 3 may be divided into a first portion 3310 including an aerosol generating material and a second portion 3320 including a filter and the like. Meanwhile, the cigarette 3 according to an embodiment may include an aerosol generating material in the second portion 3320. For example, an aerosol generating material in the form of granules or capsules may be inserted into the second portion 3320.

The entire first portion 3310 may be inserted into the holder 1, and the second portion 3320 may be exposed to the outside. Alternatively, only a part of the first part 3310 may be inserted into the holder 1, or a part of the first part 3310 and the second part 3320 may be inserted into the holder 1.

The user may inhale the aerosol in the door state by mouth of the second portion 3320. At this time, the aerosol is mixed with the outside air and delivered to the user's mouth. As shown in FIG. 16, the outside air may be introduced 3110 through at least one hole formed in the surface of the cigarette 3, and may be introduced through at least one air passage formed in the holder 1. 3120. For example, the air passage formed in the holder 1 may be manufactured to be opened and closed by a user.

17A and 17B are diagrams illustrating an example of a cigarette.

Referring to FIGS. 17A and 17B, the cigarette 3 includes a tobacco rod 3300, a first filter segment 3321, a cooling structure 3322, and a second filter segment 3323. The first portion 3310 described above with reference to FIG. 16 includes a tobacco rod 3300, and the second portion 3320 includes a first filter segment 3321, a cooling structure 3322, and a second filter segment 3323. ).

17A and 17B, the cigarette 3 of FIG. 17B further includes a fourth wrapper 3342 as compared to the cigarette 3 of FIG. 17A.

However, the structure of the cigarette 3 shown in FIGS. 17A and 17B is merely an example, and some configurations may be omitted. For example, the cigarette 3 may not include one or more of the first filter segment 3331, the cooling structure 3322, and the second filter segment 3323.

Tobacco rod 3300 includes an aerosol generating material. For example, the aerosol generating material may comprise at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and oleyl alcohol. The tobacco rod 3300 may be about 7 mm to 15 mm in length, or preferably about 12 mm. In addition, the diameter of the tobacco rod 3300 may be 7 mm to 9 mm, or preferably about 7.9 mm. The length and diameter of the tobacco rod 3300 are not limited to the above-described numerical range.

In addition, tobacco rod 3300 may contain other additive materials such as flavoring agents, wetting agents and / or acetate compounds. For example, the flavoring agent is licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, Vanilla, lemon oil, orange oil, mint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, sage, spearmint, ginger, coriander or coffee and the like. Wetting agents may also include glycerin or propylene glycol and the like.

As an example, the tobacco rod 3300 may be filled with tobacco sheaths. Here, tobacco sheaths can be produced by pulverizing tobacco sheets.

In order for the wide tobacco sheet to be filled in the tobacco rod 3300 in a narrow space, a process for additionally folding the tobacco sheet may be required. Thus, as compared to filling the tobacco rod 3300 with a tobacco sheet, it is easier to fill the tobacco rod 3300 with tobacco sheaths, and the productivity and efficiency of the process of producing the tobacco rod 3300 may be higher. have.

As another example, the tobacco rod 3300 may be filled with a plurality of tobacco strands in which the tobacco sheet is trimmed. For example, the tobacco rod 3300 may be formed by combining a plurality of tobacco strands in the same direction (parallel) or randomly. One tobacco strand may be manufactured in a rectangular parallelepiped shape having a length of 1 mm, a length of 12 mm, and a thickness (height) of 0.1 mm, but is not limited thereto.

Compared to the tobacco rod 3300 being filled with a tobacco sheet, the tobacco rod 3300 filled with tobacco strands may generate a greater amount of aerosol. Assuming that the same space is filled, compared to tobacco sheets, tobacco strands ensure a larger surface area. Large surface area means that the aerosol generating material has more chances of contacting the outside air. Thus, when the tobacco rod 3300 is filled with tobacco strands, more aerosol may be produced than with the tobacco sheet.

In addition, when the cigarette 3 is detached from the holder 1, the tobacco rod 3300 filled with tobacco strands can be more easily separated than that filled with the tobacco sheet. Compared to the tobacco sheet, the friction forces generated by the tobacco strands in contact with the heater 2130 are smaller. Thus, when the tobacco rod 3300 is filled with tobacco strands, it can be more easily separated from the holder 1 than with the tobacco sheet.

The tobacco sheet may be formed by grinding the tobacco raw material in slurry form and then drying the slurry. For example, 15-30% of the aerosol generating material may be added to the slurry. The tobacco raw material may be tobacco leaf flakes, tobacco stems, tobacco dust generated during tobacco processing and / or main lateral strips of tobacco leaves. The tobacco sheet may also contain other additives such as wood cellulose fibers.

The first filter segment 3331 may be a cellulose acetate filter. For example, the first filter segment 3321 may be in the form of a tube including a hollow therein. The length of the first filter segment 3321 may be about 7 mm to 15 mm, or preferably about 7 mm. The length of the first filter segment 3321 may be shorter than about 7 mm, but preferably has a length such that the function of at least one cigarette element (eg, cooling element, capsule, acetate filter, etc.) is not compromised. . The length of the first filter segment 3321 is not limited to the above-described numerical range. Meanwhile, the length of the first filter segment 3321 may be extended, and the length of the entire cigarette 3 may be adjusted according to the length of the first filter segment 3331.

The second filter segment 3323 may also be a cellulose acetate filter. For example, the second filter segment 3323 may be made of a recess filter including a hollow, but is not limited thereto. The length of the second filter segment 3323 may be about 5 mm to 15 mm, or preferably about 12 mm. The length of the second filter segment 3323 is not limited to the above-described numerical range.

In addition, the second filter segment 3323 may include at least one capsule 3324. Here, the capsule 3324 may be a structure wrapped in a coating film containing the fragrance. For example, the capsule 3324 may have a spherical or cylindrical shape. The diameter of the capsule 3324 may be 2 mm or more, or preferably 2 to 4 mm.

The material forming the encapsulation of the capsule 3324 may be starch and / or gelling agents. For example, gelling gum or gelatin may be used as the gelling agent. In addition, a gelling aid may further be used as a material for forming the film of the capsule 3324. Here, calcium chloride can be used as the gelling aid, for example. In addition, a plasticizer may be further used as a material for forming the film of the capsule 3324. Here, glycerin and / or sorbitol may be used as the plasticizer. In addition, a coloring agent may be further used as a material for forming a film of the capsule 3324.

For example, menthol, essential oil of a plant, etc. can be used as a fragrance contained in the capsule liquid. Moreover, as a solvent of the fragrance | flavor contained in a liquid content, medium chain fatty acid triglyceride (MCT) can be used, for example. In addition, the content solution may contain other additives such as a dye, an emulsifier, and a thickener.

The cooling structure 3322 cools the aerosol generated by the heater 2130 heating the tobacco rod 3300. Thus, the user can inhale the aerosol cooled to the appropriate temperature. The length of the cooling structure 3322 may be about 10 mm to 20 mm, or preferably about 14 mm. The length of the cooling structure 3322 is not limited to the above-described numerical range.

For example, the cooling structure 3322 can be made of polylactic acid. The cooling structure 3322 can be fabricated in various forms to increase the surface area per unit area (ie, surface area in contact with the aerosol). Various examples of the cooling structure 3322 are described below with reference to FIGS. 18A-18F.

The tobacco rod 3300 and the first filter segment 3331 may be wrapped by the first wrapper 3331. For example, the first wrapper 3331 may be made of a paper packaging material having oil resistance.

The cooling structure 3322 and the second filter segment 3323 may be wrapped by the second wrapper 3332. In addition, the entire cigarette 3 may be repackaged by the third wrapper 3333. For example, the second wrapper 3332 and the third wrapper 3333 may be made of a general paper packaging material. Optionally, the second wrapper 3332 may be oil resistant hard wrap or PLA fragrance. In addition, the second wrapper 3332 may wrap a portion of the second filter segment 3323, and may further wrap the second filter segment 3323 and the cooling structure 3322.

Referring to FIG. 17B, the cigarette 3 may include a fourth wrapper 3342. At least one of the tobacco rod 3300 and the first filter segment 3321 may be wrapped by a fourth wrapper 3342. In other words, only the tobacco rod 3300 may be wrapped by the fourth wrapper 3334, and the tobacco rod 3300 and the first filter segment 3321 may be wrapped by the fourth wrapper 3334. For example, the fourth wrapper 3342 may be made of paper package.

The fourth wrapper 3342 may be generated by applying (or coating) a predetermined material to one or both surfaces of the paper package. Here, silicon may be used as an example of the predetermined material, but is not limited thereto. Silicon has characteristics such as heat resistance with little change with temperature, oxidation resistance without oxidation, resistance to various chemicals, water repellency for water, or electrical insulation. However, even if not silicon, if the material having the above-described characteristics can be applied (or coated) to the fourth wrapper (3334) without limitation.

Meanwhile, in FIG. 17B, the cigarette 3 is illustrated to include both the first wrapper 3331 and the fourth wrapper 3334, but is not limited thereto. In other words, the cigarette 3 may include only one of the first wrapper 3331 and the fourth wrapper 3334.

The fourth wrapper 3342 can prevent the phenomenon in which the cigarette 3 is burned. For example, when the tobacco rod 3300 is heated by the heater 2130, the cigarette 3 may burn. Specifically, when the temperature rises above the ignition point of any one of the substances included in the tobacco rod 3300, the cigarette 3 may be burned. Even in this case, since the fourth wrapper 3342 contains a non-combustible material, the phenomenon in which the cigarette 3 is burned can be prevented.

In addition, the fourth wrapper 3342 may prevent the holder 1 from being contaminated by the materials generated from the cigarette 3. By the puff of the user, liquid substances can be produced in the cigarette 3. For example, the aerosol produced in the cigarette 3 is cooled by the outside air, whereby liquid substances (eg moisture) can be produced. As the fourth wrapper 3334 wraps the tobacco rod 3300 and / or the first filter segment 3331, the liquid substances produced in the cigarette 3 can be prevented from leaking out of the cigarette 3. Can be. Therefore, the phenomenon in which the case 2140 and the like of the holder 1 is contaminated by the liquid substances generated in the cigarette 3 can be prevented.

18A-18F illustrate examples of a cooling structure of a cigarette.

For example, the cooling structure shown in FIGS. 18A-18F can be fabricated using fibers produced from pure polylactic acid (PLA).

As an example, when the film (sheet) is filled to produce a cooling structure (film), the film (sheet) may be broken by an external impact. In this case, the effect of the cooling structure cooling the aerosol is reduced.

As another example, when manufacturing a cooling structure by extrusion molding or the like, as the process of cutting the structure is added, the efficiency of the process is lowered. There is also a limitation in manufacturing the cooling structure in various shapes.

As the cooling structure according to one embodiment is fabricated (eg, woven) using polylactic acid fibers, the risk of the cooling structure being deformed or lost function by external impact can be lowered. In addition, by changing the way the fibers are combined, it is possible to produce cooling structures having various shapes.

In addition, by making the cooling structure with the fibers, the surface area in contact with the aerosol is increased. Thus, the aerosol cooling effect of the cooling structure can be further improved.

Referring to FIG. 18A, the cooling structure 3510 may be manufactured in a cylindrical shape, and at least one air passage 3511 may be formed in a cross section of the cooling structure 3510.

Referring to FIG. 18B, the cooling structure 3520 may be manufactured as a structure in which a plurality of fibers are entangled with each other. In this case, the aerosol may flow between the fibers, and vortex may be formed according to the shape of the cooling structure 3520. The vortex formed increases the area that aerosol contacts in the cooling structure 3520 and increases the time the aerosol stays in the cooling structure 3520. Thus, the heated aerosol can be cooled effectively.

Referring to FIG. 18C, the cooling structure 3530 may be manufactured in the form of a plurality of bundles 3531.

Referring to FIG. 18D, the cooling structure 3540 may be filled with granules made of polylactic acid, vinegar or charcoal, respectively. Granules may also be prepared from a mixture of polylactic acid, vinegar and charcoal. On the other hand, the granules may further include elements capable of increasing the cooling effect of the aerosol in addition to polylactic acid, vinegar and / or char.

Referring to FIG. 18E, the cooling structure 3550 may include a first cross section 3551 and a second cross section 3552.

The first end surface 3551 borders the first filter segment 3321 and may include a void into which an aerosol flows. The second end surface 3652 borders the second filter segment 3323 and may include voids through which aerosols may be released. For example, the first end surface 3551 and the second end surface 3652 may include a single void having the same diameter, but the diameter and number of the pores included in the first end surface 3651 and the second end surface 3652. Is not limited thereto.

In addition, the cooling structure 3550 may include a third cross section 3553 including a plurality of voids between the first cross section 3551 and the second cross section 3552. For example, the diameters of the plurality of voids included in the third end surface 3553 may be smaller than the diameters of the voids included in the first end surface 3551 and the second end surface 3652. In addition, the number of voids included in the third end surface 3553 may be greater than the number of voids included in the first end surface 3651 and the second end surface 3652.

Referring to FIG. 18F, the cooling structure 3560 may include a first cross section 3651 that borders the first filter segment 3321 and a second cross section 3652 that borders the second filter segment 3323. . In addition, cooling structure 3560 may include one or more tubular elements 3635. For example, the tubular element 3553 can penetrate the first cross section 3651 and the second cross section 3652. In addition, the tubular element 3503 may be packaged in a microporous package and filled with a filler (eg, the granules described above with reference to FIG. 18D) that may increase the cooling effect of the aerosol.

On the other hand, the above-described method can be written as a program that can be executed in a computer, it can be implemented in a general-purpose digital computer to operate the program using a computer-readable recording medium. In addition, the structure of the data used in the above-described method can be recorded on the computer-readable recording medium through various means.
