Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 is a block diagram illustrating an aerosol-generating device 100 according to an embodiment.

The aerosol-generating device 100 illustrated in FIG. 1 may be an aerosol-generating device having a plurality of power sources and selectively operating the plurality of power sources.

The aerosol-generating device 100 may include a power supply unit 110, a control unit 120, and a heater 130.

The power supply unit 110 according to an embodiment may include a plurality of power sources. For example, the power supply unit 110 may include a first battery 111 and a second battery 113.

The first battery 111 may be a power source used when supplying power to the heater 130 according to the first mode. For example, the first mode may be a mode (preheating mode) for raising the temperature of the heater 130 to a temperature at which aerosol is generated.

The first battery 111 according to an embodiment may include a lithium ion capacitor. The first battery 111 may be formed of, for example, two or more lithium ion capacitor groups. Each group can include one or more lithium ion capacitors connected in series.

According to an embodiment, when the first battery 111 is a lithium ion capacitor, an average rate of charging and discharging of the first battery 111 may be about 50C (C-rate), but is not limited thereto. For example, when the first battery 111 is a lithium ion capacitor, the first battery 111 may be charged and discharged about 5 to 10 times faster than a lithium iron phosphate battery.

Further, according to an embodiment, when the first battery 111 is a lithium ion capacitor, the number of charge/discharge cycles may be increased by about 2 to 4 times compared to when the lithium iron phosphate battery is charged and discharged. For example, in the case of a lithium iron phosphate battery, when the number of times that it can be used while repeating charging and discharging completely is about 2,000 times, the first battery 111 is the first battery 111 when the lithium battery is a lithium ion capacitor. The number of times the battery can be fully charged and discharged may be about 8000 times.

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

The second battery 113 may be a power source used when power is supplied to the heater 130 according to the second mode. For example, the second mode may be a mode (smoking mode) for maintaining the temperature of the heater 130.

The second battery 113 according to an embodiment may include one of a lithium-ion cell battery, a lithium iron phosphate battery, a lithium titanate battery, and a lithium polymer battery.

According to an embodiment, greater power may be supplied to the heater 130 in the first mode than in the second mode.

The first mode may be a mode in which high power is required for a short time, and the second mode may be a mode in which high power is not required.

For example, the first mode may include a preheating mode. The preheating mode is a mode in which the heater 130 is raised to a temperature for generating an aerosol when the user wants to start smoking. In the preheating mode, since the temperature of the heater 130 should be heated from room temperature to about 200 degrees, high power is required.

The second mode may include a smoking mode. The smoking mode is a mode in which the temperature of the heater 130 is maintained when the user wants to continue smoking after the heater 130 is preheated to a temperature suitable for generating an aerosol. In order to maintain the temperature of the heater 130 in the smoking mode, a high output is not required compared to when the heater 130 is preheated.

According to an embodiment, when the first battery is a lithium ion capacitor, it may take about 10 seconds to increase the temperature of the heater 130 to the aerosol-generating temperature in the preheating mode.

According to an embodiment, when a lithium ion capacitor is used as the first battery when power is supplied to the heater 130 according to the preheating mode, compared to when using a lithium iron phosphate battery, it is required to preheat the heater 130. Time can be reduced to 1/3.

The control unit 120 is configured to control the entire operation of the aerosol-generating device 100. The controller 120 controls the operation of the battery 110 and the heater 130 as well as other components included in the aerosol-generating device 100. In addition, the control unit 120 may determine the state of each of the components of the aerosol generating device 100 to determine whether the aerosol generating device 100 is in an operable state.

The control unit 120 may include a microprocessor or microcontroller. For example, the controller 120 may be implemented as an array of multiple logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory in which programs that can be executed in the microprocessor are stored. In addition, those skilled in the art to which this embodiment belongs may understand that it may be implemented with other types of hardware.

The control unit 120 may control the power supply unit to operate according to the preheating mode when sensing the user's suction. The user's inhalation can be sensed through a separate sensor (not shown).

The aerosol-generating device 100 according to an embodiment may enter a preheating mode by a user turning on a separate switch (not shown).

The control unit 120 controls the power supply unit 110 to operate according to the first mode while the temperature of the heater 130 rises to the critical temperature, and when the temperature of the heater 130 exceeds the critical temperature, the control unit 120 The power supply unit 110 may be controlled to operate in two modes.

The critical temperature may be a temperature at which aerosol is generated from the aerosol-forming substrate. The critical temperature may be set differently depending on the type of aerosol-forming substrate heated by the heater 130.

The controller 120 may control the power supply to operate according to the first mode during the first time, and control the power supply to operate according to the second mode when the first time elapses.

The first time according to an embodiment may be a time required for the temperature of the heater 130 to rise from the aerosol-forming substrate to an appropriate critical temperature at which aerosol is generated.

On the other hand, the control unit 120 detects the user's suction, and when the temperature of the heater 130 is below the first temperature, the power supply unit 110 may operate according to the first mode. The first temperature can be set to, for example, about 60% to 80% of a critical temperature at which aerosol is generated from the aerosol-forming substrate.

Here, the first temperature may range from 300 to 350 degrees, and the range may be appropriately changed according to the type of cigarette.

When the temperature of the heater 130 is lower than or equal to the first temperature, after sensing the user's suction, a rather large output may be required to increase the temperature of the heater 130 to a critical temperature. In this case, the control unit 120 may cause the power supply unit 110 to operate according to a first mode using the first battery 111.

In addition, the control unit 120 may detect the user's suction, and control the power supply unit 110 to operate according to the second mode when the temperature of the heater 130 exceeds the first temperature.

When the temperature of the heater 130 exceeds the first temperature, after sensing the user's suction, a large output may not be required to increase the temperature of the heater 130 to a critical temperature. In this case, the control unit 120 may cause the power supply unit 110 to operate according to a second mode using the second battery 113.

The first temperature may be set differently according to the type of aerosol-forming substrate heated by the heater 130. In addition, the first temperature may be set differently according to the aerosol generating device 100.

In addition, the controller 120 may check the presence or absence of the puff of the user and the strength of the puff, and may count the number of puffs. In addition, the control unit 120 may continuously check the time the aerosol generating device 100 is operating. In addition, the control unit 120 checks whether the filling device 200 to be described later is combined with the aerosol generating device 100, and the aerosol generating device according to the combination or separation of the filling device 200 and the aerosol generating device 100 The operation of the (100) can be controlled.

The heater 130 may be configured to heat the aerosol-forming substrate 101 by electric power supplied from the power supply unit 110.

When the aerosol-forming substrate 101 is accommodated inside the cavity 103, the heater 130 may be located inside the aerosol-forming substrate 101. Accordingly, the heated heater 130 may increase the temperature of the aerosol-generating material contained in the aerosol-forming substrate 101.

The heater 130 may be an electric resistive heater. For example, the heater 130 includes an electrically conductive track, and as the current flows through the electrically conductive track, the heater 130 may be heated.

The heater 130 may be composed of at least one electrically conductive track (first electrically conductive track and second electrically conductive track). For example, the heater 130 may be composed of two first electrically conductive tracks and one or two second electrically conductive tracks, but is not limited thereto. For example, the heater 130 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, and the temperature T of the second electrically conductive track can be determined according to the resistance. have.

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

For stable use, the heater 130 may be supplied with power according to the specifications of 3.2 V, 2.4 A, 8 W, but is not limited thereto. For example, when power is supplied to the heater 130, the surface temperature of the heater 130 may increase to 400°C or higher. The surface temperature of the heater 130 may rise to about 350° C. before 15 seconds are exceeded from when power is supplied to the heater 130.

The sensor unit 140 according to an embodiment may include a sensor for detecting the temperature of the heater.

In addition, the sensor unit 140 is not configured as a separate temperature sensing sensor, but may be configured to be included in the heater 130 to serve as a temperature sensing sensor.

In addition, the aerosol-generating device 100 may include both an electrically conductive track and a temperature sensing sensor that serve as a temperature sensing sensor.

In addition, the sensor unit 140 may include a suction sensor for detecting a user's suction. The suction sensor includes a sensor capable of detecting a change in air flow or pressure according to the user's suction.

The memory 150 according to an embodiment may store various data, programs, or applications for driving and controlling the aerosol-generating device 100.

Also, the memory 150 may store a condition for switching from 1 mode to the 2nd mode. Conditions for switching from the first mode to the second mode may include a temperature of the heater and a time when the power supply is operated according to the first mode.

Meanwhile, the memory 150 is illustrated as a separate component from the control unit 120, but may be a component included in the control unit 120.

Meanwhile, the aerosol generating device 100 may further include general-purpose components in addition to the power supply unit 110, the control unit 120, the heater 130, the sensor unit 140, and the memory 150.

For example, the aerosol generating apparatus 100 may include a display capable of outputting visual information or a motor for outputting tactile information. As an example, when the aerosol-generating device 100 includes a display, the control unit 120 displays information about the state of the aerosol-generating device 100 to the user (eg, whether it is usable or not) through the display. Information about the heater 130 (for example, start of preheating, progress of preheating, completion of preheating, etc.), information related to the power supply unit 110 (for example, the remaining capacity of the battery of the power supply unit 110, whether or not available) Etc.), information related to the reset of the aerosol-generating device 100 (e.g., reset timing, reset progress, reset completion, etc.), information related to cleaning of the aerosol-generating device 100 (e.g., cleaning timing, cleaning Necessary, cleaning progress, cleaning completion, etc.), information related to charging of the aerosol-generating device 100 (e.g., charging required, filling progress, filling completion, etc.), information related to puffs (e.g., number of puffs, puffs) You can send information such as the strength of the notice of puff termination) or safety-related information (for example, elapsed use time).

The battery 3110 may be a lithium iron phosphate (LiFePO4) battery, but is not limited to the above-described example. For example, the battery 3110 may be a lithium cobalt oxide (LiCoO2) battery, a lithium titanate battery, or the like.

In addition, the battery 3110 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 3110 may be 120mAh or more, and may be a rechargeable battery or a disposable battery. For example, when the battery 3110 can be charged, the charging rate (C-rate) of the battery 3110 may be 10C, and the discharge rate (C-rate) may be 16C to 20C, but is not limited thereto. In addition, for stable use, the battery 3110 may be manufactured so that 80% or more of the total capacity can be secured even when charging/discharging proceeds 8000 times.

Here, whether the battery 3110 is fully charged or completely discharged may be determined by which level of power stored in the battery 3110 is compared to the total capacity of the battery 3110. For example, when the power stored in the battery 3110 is 95% or more of the total capacity, it may be determined that the battery 3110 is fully charged. In addition, when the power stored in the battery 3110 is 10% or less of the total capacity, it may be determined that the battery 3110 is completely discharged. However, the criteria for determining whether the battery 3110 is fully charged and fully discharged is not limited to the above-described example.

The heater 3130 is heated by electric power supplied from the battery 3110. When the cigarette is inserted into the holder 3100, the heater 3130 is located inside the cigarette. Thus, the heated heater 3130 can increase the temperature of the aerosol-generating material in the cigarette.

The heater 3130 may have a shape in which a cylinder and a cone are combined. The diameter of the heater 3130 may be an appropriate size in the range of 2mm to 3mm. Preferably, the heater 3130 may be manufactured to have a diameter of 2.15mm, but is not limited thereto. In addition, the length of the heater 3130 may be an appropriate size in the range of 20mm to 30mm. Preferably, the heater 3130 may be manufactured to have a length of 19mm, but is not limited thereto. In addition, the end 131 of the heater 3130 may be closed at an acute angle, but is not limited thereto. In other words, the heater 3130 may be applied without limitation as long as it can be inserted into the cigarette. In addition, only a portion of the heater 3130 may be heated. For example, assuming that the length of the heater 3130 is 19 mm, only 12 mm from the end 131 of the heater 3130 is heated, and the rest of the heater 3130 may not be heated.

The heater 3130 may be an electric resistive heater. For example, the heater 3130 includes an electrically conductive track, and as the current flows through the electrically conductive track, the heater 3130 may be heated.

For stable use, electric power according to the specifications of 3.2 V, 2.4 A, and 8 W may be supplied to the heater 3130, but is not limited thereto. For example, when power is supplied to the heater 3130, the surface temperature of the heater 3130 may rise to 400°C or higher. The surface temperature of the heater 3130 may rise to about 350° C. before 15 seconds are exceeded from when power is supplied to the heater 3130.

The holder 3100 may be provided with a separate temperature sensor. Alternatively, the temperature sensor is not provided in the holder 3100, and the heater 3130 may function as a temperature sensor. Alternatively, while the heater 3130 of the holder 3100 functions as a temperature sensor, the holder 3100 may further be provided with a separate temperature sensor. In order for the heater 3130 to function as a temperature sensor, the heater 3130 may include at least one electrically conductive track for heat generation and temperature detection. In addition, the heater 3130 may include a second electrically conductive track for temperature sensing in addition to the first electrically conductive track for heat generation.

For example, when 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 (for example, 0°C), and α is the resistance temperature of the second electrically conductive track Means a coefficient. Since the conductive material (eg, metal) has an intrinsic resistance temperature coefficient, α may be determined in advance depending on the conductive material constituting the second electrically conductive track. Accordingly, 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.

The heater 3130 may be composed of at least one electrically conductive track (first electrically conductive track and second electrically conductive track). For example, the heater 3130 may be composed of two first electrically conductive tracks and one or two second electrically conductive tracks, but is not limited thereto.

The processor may be implemented as an array of multiple logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory in which programs executable on the microprocessor are stored. In addition, those skilled in the art to which this embodiment belongs may understand that it may be implemented with other types of hardware.

For example, the control unit 3120 may control the operation of the heater 3130. The control unit 3120 may control the amount of power supplied to the heater 3130 and the time during which the power is supplied so that the heater 3130 is heated to a predetermined temperature or maintain an appropriate temperature. In addition, the control unit 3120 may check the state of the battery 3110 (eg, the remaining amount of the battery 3110, etc.), and generate a notification signal if necessary.

In addition, the control unit 3120 may check the presence or absence of the puff of the user and the strength of the puff, and count the number of puffs. In addition, the control unit 3120 may continuously check the time when the holder 3100 is operating.

As the user operates the input device, the holder 3100 has a function of preheating the heater 3130, a function of adjusting the temperature of the heater 3130, a function of cleaning the space where the cigarette is inserted, and a holder 3100 A function of checking whether it is in an operable state, a function of displaying the remaining amount (power available) of the battery 3110, a reset function of the holder 3100, and the like can be performed. However, the function of the holder 3100 is not limited to the examples described above.

For example, the holder 3100 can clean the space where the cigarette is inserted by controlling the heater 3130 as follows. For example, the holder 3100 can clean the space where the cigarette is inserted by heating the heater 3130 to a sufficiently high temperature. Here, a sufficiently high temperature means a temperature suitable for cleaning the space where the cigarette is inserted. For example, the holder 3100 may heat the heater 3130 to the highest temperature among the temperature range in which aerosol can be generated in the inserted cigarette and the temperature range for preheating the heater 3130, but is not limited thereto. .

In addition, the holder 3100 can maintain the temperature of the heater 3130 at a sufficiently high temperature for a predetermined time period. Here, the predetermined time period means a time period sufficient to clean the space where the cigarette is inserted. For example, the holder 3100 may maintain the temperature of the heater 3130 heated for a suitable time during a time period of 10 seconds to 10 minutes, but is not limited thereto. Preferably, the holder 3100 is capable of maintaining the temperature of the heater 3130 heated for a suitable time period selected within the range of 20 seconds to 1 minute. In addition, preferably, the holder 3100 can maintain the temperature of the heater 3130 heated for a suitable time period selected within the range of 20 seconds to 1 minute 30 seconds.

Here, the electrically conductive track includes an electrically conductive track for heat generation and/or an electrically conductive track for temperature sensing. Alternatively, the holder 3100 may further include a puff detection sensor separately from sensing the puff using the electrically conductive track included in the heater 3130.

The cigarette insertion detection sensor may be implemented by a general capacitive sensor or a resistance sensor. In addition, the holder 3100 may be manufactured in a structure that allows external air to flow in/out even when a cigarette is inserted.

Hereinafter, examples in which the holder 3100 is inserted into the cradle 3200 will be described with reference to FIGS. 10 to 12B.

10 is a view showing an example in which the holder is inserted into the cradle.

Referring to FIG. 10, an example in which the holder 3100 is inserted into the cradle 3200 is illustrated. Since the space 3230 in which the holder 3100 is to be inserted exists on one side of the cradle 3200, the inserted holder 3100 may not be exposed to the outside by the other sides of the cradle 3200. Accordingly, the cradle 3200 may not include other configurations (eg, lids) for not exposing the holder 3100 to the outside.

The cradle 3200 may include at least one binding member 3327, 3272 to increase the binding strength with the holder 3100. Also, the holder 3100 may include at least one binding member 3181. Here, the binding members 3181, 3271, and 3272 may be magnets, but are not limited thereto.

The holder 3100 may include a binding member 3181 in a first position, and the cradle 3200 may include a binding member 3327 and 3272 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 3100 is inserted into the cradle 3200.

As the holder 3100 and the cradle 3200 include binding members 3181, 3271, and 3272, even if the holder 3100 is inserted into one side of the cradle 3200, the holder 3100 and the cradle 3200 are It can bind more strongly. In other words, the holder 3100 and the cradle 3200, the terminal (3170, 3260) in addition to the binding member (3181, 3271, 3272) is further included, the holder 3100 and the cradle (3200) can be more strongly coupled have. Therefore, even if there is no separate configuration (eg, a lid) in the cradle 3200, the inserted holder 3100 may not be easily separated from the cradle 3200.

In addition, if it is determined that the holder 3100 is completely inserted into the cradle 3200 by the terminals 3170, 3260 and/or the binding members 3181, 3271, 3272, the control unit 3220 may control the battery 3210. The battery 3110 of the holder 3100 may be charged using electric power.

)은 10°가 될 수 있다.11, when the holder 3100 is tilted, the end 3141 of the holder 3100 is exposed to the outside. Therefore, the user can insert a cigarette at the end 3141 and inhale (smoking) the generated aerosol. Tilt angle (

) When the cigarette is inserted into the end 3141 of the holder 3100, a sufficient angle can be secured so that the cigarette is not bent or damaged. For example, the holder 3100 may be tilted at a minimum angle or a larger angle at which the entire cigarette insertion hole included in the end 3141 is exposed to the outside. For example, the tilt angle (

) May be in the range of 0° or more and 180° or less, and preferably 5° or more and 90° or less. More preferably, the tilt angle (

) May range from 5° to 20°, 5° to 30°, 5° to 40°, 5° to 50°, or 5° to 60°. More preferably, the tilt angle (

) May be 10°.

Further, even if the holder 3100 is tilted, the terminal 3170 of the holder 3100 and the terminal 3260 of the cradle 3200 are coupled to each other. Therefore, the heater 3130 of the holder 3100 may be heated by electric power supplied by the battery 3210 of the cradle 3200. Therefore, even when the remaining amount of the battery 3110 of the holder 3100 is small or absent, the holder 3100 may generate an aerosol using the battery 3210 of the cradle 3200.

11 shows an example in which the holder 3100 includes one binding member 182 and the cradle 3200 includes two binding members 3273 and 3274. For example, the positions of each of the binding members 3182, 3273, and 3274 are as described above with reference to FIG. If it is assumed that the binding members 3182, 3273, and 3274 are magnets, the magnet strength of the binding member 3274 may be greater than that of the binding member 3272. Accordingly, even if the holder 3100 is tilted, the holder 3100 may not be completely separated from the cradle 3200 by the binding member 3182 and the binding member 3274.

In addition, when it is determined that the holder 3100 is tilted by the terminals 3170, 3260 and/or the binding members 3182, 3273, 3274, the control unit 3220 uses the power of the battery 3210 to hold the holder. The heater 3130 of the 3100 may be heated, or the battery 3110 may be charged.

12A to 12B are views illustrating examples in which the holder is inserted into the cradle.

12A shows an example in which the holder 3100 is completely inserted into the cradle 3200. When the holder 3100 is completely inserted into the cradle 3200, in order to minimize the user's contact with the holder 3100, the inner space 3230 of the cradle 3200 may be manufactured to be sufficiently secured. When the holder 3100 is completely inserted into the cradle 3200, the control unit 3220 supplies the power of the battery 3210 to the holder 3100 so that the battery 3110 of the holder 3100 can be charged.

12B shows an example in which the holder 3100 is tilted in the state where the cradle 3200 is inserted. When the holder 3100 is tilted, the control unit 3220, the battery 3110 of the holder 3100 is charged, or the heater 3130 of the holder 3100 can be heated, so that the power of the battery 3210 holder (3100).

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

The method of producing the aerosol shown in FIG. 13 consists of steps that are processed in time series in the holder 3100 shown in FIG. 6 or the cradle 3200 shown in FIG. 8. Accordingly, it can be seen that the contents described above with respect to the holder 3100 illustrated in FIG. 6 and the cradle 3200 illustrated in FIG. 8 are applied to the method illustrated in FIG. 13 even if omitted below.

In step 3810, the holder 3100 determines whether it is inserted into the cradle 3200. For example, the controller 3120 may control the holder 3 according to whether the holders 3100 and the terminals 3170 and 3260 of the cradle 3200 are connected to each other and/or whether the binding members 3181, 3271, and 3272 operate. It is possible to determine whether 3100) is inserted into the cradle 3200.

When the holder 3100 is inserted into the cradle 3200, the process proceeds to step 3820, and when the holder 3100 is separated from the cradle 3200, the process proceeds to step 3830.

In step 3820, the cradle 3200 determines whether the holder 3100 is tilted. For example, the control unit 3220 may include the holder 3100 and the terminals 3170, 3260 of the cradle 3200 connected to each other and/or whether the binding members 3182, 3273, 3274 operate. 3100) can be determined whether or not tilted.

In step 3820, the cradle 3200 is described as determining whether the holder 3100 is tilted, but is not limited thereto. In other words, whether the holder 3100 is tilted may be determined by the control unit 3120 of the holder 3100.

When the holder 3100 is tilted, the process proceeds to step 3840, and when the holder 3100 is not tilted (ie, when the holder 3100 is completely inserted into the cradle 3200), the process proceeds to step 3870.

In step 3830, the holder 3100 determines whether the use conditions of the holder 3100 are satisfied. For example, the control unit 3120 may determine whether the use condition is satisfied by checking whether the remaining amount of the battery 3110 and other components of the holder 3100 can operate normally.

If the use condition of the holder 3100 is satisfied, the process proceeds to step 3840, otherwise, the procedure ends.

In step 3840, the holder 3100 notifies the user that it is available. For example, the control unit 3120 may output an image indicating that it is available for display on the holder 3100, or may generate a vibration signal by controlling the motor of the holder 3100.

In step 3850, the heater 3130 is heated. As an example, when the holder 3100 is separated from the cradle 3200, the heater 3130 may be heated by the power of the battery 3110 of the holder 3100. As another example, when the holder 3100 is tilted, the heater 3130 may be heated by the power of the battery 3210 of the cradle 3200.

The control unit 3120 of the holder 3100 or the control unit 3220 of the cradle 3200 checks the temperature of the heater 3130 in real time to supply the amount of power supplied to the heater 3130 and power to the heater 3130 You can adjust the time. For example, the controllers 3120 and 3220 may check the temperature of the heater 3130 in real time through the temperature sensing sensor included in the holder 3100 or the electrically conductive track of the heater 3130.

In step 3860, the holder 3100 performs an aerosol-generating mechanism. For example, the controllers 3120 and 3220 check the temperature of the heater 3130 that changes as the user performs a puff to adjust the amount of power supplied to the heater 3130 or supply power to the heater 3130. You can stop. In addition, the control units 3120 and 3220 may count the number of puffs of the user, and output information indicating that cleaning of the holder is necessary when a certain number of puffs (for example, 1500 times) is reached.

In step 3870, the cradle 3200 performs charging of the holder 3100. For example, the control unit 3220 may charge the holder 3100 by supplying the power of the battery 3210 of the cradle 3200 to the battery 3110 of the holder 3100.

Meanwhile, the controllers 3120 and 3220 may stop the operation of the holder 3100 according to the number of puffs of the user or the operation time of the holder 3100. Hereinafter, an example in which the control units 3120 and 3220 stop the operation of the holder 3100 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 of time-series processing in the holder 3100 shown in FIG. 6 and the cradle 3200 shown in FIG. 8. Accordingly, it can be seen that the contents described above with respect to the holder 3100 illustrated in FIG. 6 or the cradle 3200 illustrated in FIG. 8 are applied to the method illustrated in FIG. 14 even if omitted below.

In step 3910, the controller 3120, 3220 determines whether the user has puffed. For example, the control units 3120 and 3220 may determine whether the user has puffed through the puff detection sensor included in the holder 3100. Alternatively, the controllers 3120 and 3220 may determine whether the user has puffed by using a change in resistance of the electrically conductive track included in the heater 3130. Here, the electrically conductive track includes an electrically conductive track for heat generation and/or an electrically conductive track for temperature sensing. Alternatively, the controllers 3120 and 3220 may determine whether the user has puffed by using both the resistance change of the electrically conductive track included in the heater 3130 and the puff detection sensor.

In step 3920, an aerosol is generated according to the user's puff. The control units 3120 and 3220 can adjust the power supplied to the heater 3130 according to the temperature of the user's puff and heater 3130 as described above with reference to FIG. 13. Also, the control units 3120 and 3220 count the number of puffs of the user.

In step 3930, the controllers 3120 and 3220 determine whether the number of puffs of the user is greater than or equal to the number of puffs. For example, assuming that the puff limit number is set to 14, the controllers 3120 and 3220 determine whether the counted puff count is 14 or more. However, the number of puff limitations is not limited to 14. For example, the puff limit number may be set to an appropriate number of 10 to 16 times.

On the other hand, when the number of puffs of the user approaches the limit of puffs (for example, when the number of puffs of the user is 12), the controllers 3120 and 3220 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 number of puffs, the process proceeds to step 3950, and if the number of puffs of the user is less than the number of puffs, the process proceeds to step 3940.

In step 3940, the controllers 3120 and 3220 determine whether the time at which the holder 3100 is operated is equal to or greater than the operation time limit. Here, the time when the holder 3100 is operated means the time accumulated from the time when the holder starts to the operation. For example, assuming that the operation timeout period is set to 10 minutes, the controllers 3120 and 3220 determine whether the holder 3100 is operating for 10 minutes or longer.

On the other hand, when the operation time of the holder 3100 is close to the operation time limit (for example, when the holder 3100 is operating for 8 minutes), the control units 3120 and 3220 may signal a warning through a display or a vibration motor. Can output

If the holder 3100 is operating beyond the operation time limit, the process proceeds to step 3950, and when the holder 3100 has an operation time less than the operation time limit, the process proceeds to step 3920.

In step 3950, the controllers 3120 and 3220 forcibly end the operation of the holder. In other words, the control units 3120 and 3220 stop the aerosol generating mechanism of the holder. For example, the controllers 3120 and 3220 may forcibly terminate the operation of the holder by cutting off power supplied to the heater 3130.

15 is a flowchart for explaining an example of the operation of the cradle.

The flowchart shown in FIG. 15 is composed of steps processed in time series in the cradle 3200 shown in FIG. 8. Accordingly, it can be seen that the contents described above with respect to the cradle 3200 shown in FIG. 8 are applied to the flowchart of FIG. 15 even if the contents are omitted below.

Although not illustrated in FIG. 15, the operation of the cradle 3200 described below may be performed regardless of whether the holder 3100 is inserted into the cradle 3200.

In step 4010, the control unit 3220 of the cradle 3200 determines whether the button 3240 is pressed. If the button 3240 is pressed, the process proceeds to step 4020, and if the button 3240 is not pressed, the process proceeds to step 4030.

In step 4020, the cradle 3200 displays the status of the battery. For example, the controller 3220 may output information about the current state (eg, remaining amount of battery) of the battery 3210 to the display 3250.

In step 4030, the control unit 3220 of the cradle 3200 determines whether a cable is connected to the cradle 3200. For example, the control unit 3220 determines whether a cable is connected to an interface (eg, a USB port) included in the cradle 3200. If the cable is connected to the cradle 3200, the process proceeds to step 4040, otherwise the procedure ends.

In step 4040, the cradle 3200 performs a charging operation. For example, the cradle 3200 charges the battery 3210 using power supplied through a connected cable.

As described above with reference to FIG. 6, a cigarette may be inserted into the holder 3100. The cigarette contains an aerosol-generating material, and aerosol is generated by the heated heater 3130.

Hereinafter, an example of a cigarette that can be inserted into the holder 3100 will be described with reference to FIGS. 16 to 18F.

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

Referring to FIG. 16, the cigarette 3300 may be inserted into the holder 3100 through the end 3141 of the case 3140. When the cigarette 3300 is inserted, the heater 3130 is located inside the cigarette 3300. Thus, the aerosol-generating material of the cigarette 3300 is heated by the heated heater 3130, thereby generating an aerosol.

The cigarette 3300 may be similar to a general combustion type cigarette. For example, the cigarette 3300 may be divided into a first portion 3310 including an aerosol-generating material and a second portion 3320 including a filter. Meanwhile, the cigarette 3300 according to an embodiment may include an aerosol-generating material in the second portion 3320. For example, an aerosol-generating material made in the form of granules or capsules may be inserted into the second portion 3320.

The entire first portion 3310 is inserted into the holder 3100, and the second portion 3320 may be exposed to the outside. Alternatively, only a portion of the first portion 3310 may be inserted into the holder 3100, or a portion of the first portion 3310 and the second portion 3320 may be inserted.

The user may inhale the aerosol in the state where the second part 3320 is opened by mouth. At this time, the aerosol is generated by the external air passing through the first portion 3310, and the generated aerosol passes through the second portion and is delivered to the user's mouth.

External air may be introduced 5120 through at least one air passage formed in the holder 3100. For example, opening and closing of the air passage and/or the size of the air passage formed in the holder 3100 may be adjusted by the user. Accordingly, the amount of atomization, smoking sensation, and the like can be adjusted by the user.

Alternatively, external air may be introduced 5110 through at least one hole formed on the surface of the cigarette 3300.

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

17A and 17B, the cigarette 3300 includes a tobacco rod 3310, 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 3310, and the second portion 3320 includes a first filter segment 3321, a cooling structure 3322, and a second filter segment 3323 ).

Referring to Figure 17a, the cigarette 3300 may be packaged by a total of five wrappers (3341, 3342, 3343, 3344, 3345). On the other hand, referring to Figure 17b, the cigarette 3300 may be packaged by a total of six wrappers (3341, 3342, 3343, 3344, 3346, 3347). The tobacco rod 3310 is packaged by a first wrapper 3331, and the first filter segment 3321 is packaged by a second wrapper 3332. Further, the cooling structure 3322 is packaged by a third wrapper 3333, and the second filter segment 3323 is packaged by a fourth wrapper 3344.

The fifth wrapper 3345 of FIG. 17A may be surrounded on the outer peripheries of the first wrapper 3331, the second wrapper 3342, the third wrapper 3333, and the fourth wrapper 3344. In other words, the entire cigarette 3300 may be double packed by the fifth wrapper 3345.

On the other hand, the sixth wrapper 3346 of FIG. 17B may be surrounded by the outer edges of the first wrapper 3331, the second wrapper 3342, and the third wrapper 3432. In other words, the cigarette rod 3310, the first filter segment 3321, and the cooling structure 3322 of the cigarette 3300 may be double packed by the sixth wrapper. In addition, the seventh wrapper 3347 of FIG. 17B may be surrounded by at least a portion of the third wrapper 3343 and the outer periphery of the fourth wrapper 3344. In other words, at least a portion of the cooling structure 3322 of the cigarette 3300 and the second filter segment 3323 may be repackaged by a seventh wrapper 3335.

The first wrapper 3331 and the second wrapper 3342 may be made of a general filter wrapper. For example, the first wrapper 3331 and the second wrapper 3342 may be porous wrappers or non-porous wrappers. In addition, the first wrapper 3331 and the second wrapper 3322 may be made of oil-resistant paper and aluminum lamination packaging.

The third wrapper 3343 may be made of hard wrapper. For example, the basis weight of the third wrapper 3343 may be 90 g/m2, but is not limited thereto.

The fourth wrapper 3344 may be made of an oil-resistant hard wrapper. For example, the basis weight of the fourth wrapper 3344 is 92g/m2, and the thickness may be 125um, but is not limited thereto.

The fifth wrapper 3345, the sixth wrapper 3346, and the seventh wrapper 3347 may be made of sterile paper (MFW). Here, sterile paper (MFW) refers to paper specially manufactured to improve tensile strength, water resistance, smoothness, and the like than ordinary paper. For example, the basis weight of the fifth wrapper 3345, the sixth wrapper 3346, and the seventh wrapper 3347 is 60 g/m2, and the thickness may be 67 μm, but is not limited thereto. In addition, the tensile strength of the fifth wrapper 3345, the sixth wrapper 3346, and the seventh wrapper 3347 may be within a range of 8 kgf/15 mm to 11 kgf/15 mm on a dry basis, and 1.0 kgf/15 mm on a wet basis, It is not limited.

A predetermined material may be added to the fifth wrapper 3345, the sixth wrapper 3346, and the seventh wrapper 3335. Here, as an example of a predetermined material, silicon may be applicable, but is not limited thereto. For example, silicone has characteristics such as heat resistance with little change with temperature, oxidation resistance without oxidation, resistance to various chemicals, water repellency to water, or electrical insulation. However, even if it is not silicon, a material having the above-described properties may be applied (or coated) to the fifth wrapper 3345, the sixth wrapper 3346, and the seventh wrapper 3347 without limitation.

The fifth wrapper 3345, the sixth wrapper 3346, and the seventh wrapper 3347 can prevent the cigarette 3300 from being burned. For example, when the cigarette rod 3310 is heated by the heater 3130, there is a possibility that the cigarette 3300 is burned. Specifically, when the temperature rises above the ignition point of any one of the substances included in the cigarette rod 3310, the cigarette 3300 may be burned. Even in this case, since the fifth wrapper 3345, the sixth wrapper 3346, and the seventh wrapper 3335 contain a non-combustible material, the phenomenon in which the cigarette 3300 is burned can be prevented.

In addition, the fifth wrapper 3345, the sixth wrapper 3346, and the seventh wrapper 3347 can prevent the holder 3100 from being contaminated by materials generated in the cigarette 3300. Liquid substances may be generated in the cigarette 3300 by the user's puff. For example, the aerosol generated in the cigarette 3300 is cooled by external air, whereby liquid substances (eg, moisture, etc.) may be generated. Liquid generated in the cigarette 3300 as the fifth wrapper 3345, the sixth wrapper 3346 and the seventh wrapper 3335 wrap the tobacco rod 3310 and/or the first filter segment 3321 Materials may be prevented from leaking out of the cigarette 3300. Therefore, a phenomenon in which the case 3140 of the holder 3100 or the like is contaminated by the liquid substances generated in the cigarette 3300 can be prevented.

The diameter of the cigarette 3300 is within the range of 5 mm to 9 mm, and the length may be about 48 mm, but is not limited thereto. Preferably, the diameter of the cigarette 3300 may be 7.2 mm, but is not limited thereto. In addition, the length of the tobacco rod 3310 is about 12 mm, the length of the first filter segment 3321 is about 10 mm, the length of the cooling structure 3322 is about 14 mm, and the length of the second filter segment 3323 is about 12 mm. However, it is not limited thereto.

The structure of the cigarette 3300 shown in FIGS. 17A and 17B is only an example, and some components may be omitted. For example, the cigarette 3300 may not include one or more of the first filter segment 3321, the cooling structure 3322, and the second filter segment 3323.

Cigarette rod 3310 includes aerosol-generating material. For example, the aerosol-generating material may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and oleyl alcohol.

In addition, the tobacco rod 3310 may contain other additives, such as flavoring agents, wetting agents and/or organic acids. For example, flavoring agents are 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. Further, the wetting agent may include glycerin or propylene glycol.

As an example, the tobacco rod 3310 may be filled with tobacco cuts. Here, tobacco cuts can be produced by finely cutting the tobacco sheet.

In order for the wide tobacco sheet to be filled in the narrow space of the tobacco rod 3310, a special process for allowing the tobacco sheet to be easily folded is additionally required. Therefore, compared to filling the cigarette rod 3310 with a cigarette sheet, it is easier to fill the cigarette rod 3310 with cigarette cuts, and the productivity and efficiency of the process for producing the cigarette rod 3310 can be higher. have.

As another example, the tobacco rod 3310 may be filled with a plurality of tobacco strands in which a tobacco sheet is shredded. For example, the tobacco rod 3310 may be formed by combining a plurality of tobacco strands in the same direction (parallel) or randomly. Specifically, the cigarette rod 3310 may be formed by combining a plurality of cigarette strands, and a plurality of channels in the longitudinal direction through which the heater 3130 may be inserted or through which an aerosol may pass may be formed. At this time, depending on the size and arrangement of the tobacco strands, the longitudinal channels may be uniform or non-uniform.

For example, tobacco strands can be prepared by the following procedure. First, the aerosol-generating material (for example, glycerin, propylene glycol, etc.), a fragrance, a binder (for example, guar gum, xanthan gum, Carboxymethyl cellulose (CMC), etc.), water by crushing tobacco raw materials, water After making the slurry mixed with the like, a sheet is formed using the slurry. When making a slurry, natural pulp or cellulose may be added to modify the properties of the tobacco strands, and one or more binders may be mixed and used. Then, after drying the sheet, the dried sheet can be cut or shredded to produce tobacco strands.

The tobacco raw material may be tobacco leaf flakes, tobacco stems and/or tobacco fines generated during tobacco processing. In addition, the tobacco sheet may contain other additives such as wood cellulose fiber.

5% to 40% of the aerosol-generating material may be added to the slurry, and 2% to 35% of the aerosol-generating material may remain in the tobacco strand finished product. Preferably, 10% to 25% of aerosol-generating material may remain in the tobacco strand finished product.

In addition, before the process in which the tobacco rod 3310 is packaged by the first wrapper 3331, a flavoring liquid such as menthol or moisturizer may be added by spraying the center of the tobacco rod 3310.

Tobacco strands may be manufactured in a cuboid shape having a horizontal length of 0.5 mm to 2 mm, a vertical length of 5 mm to 50 mm, and a thickness (height) of 0.1 mm to 0.3 mm, but is not limited thereto. Preferably, the tobacco strand may be manufactured in a cuboid shape having a width of 0.9 mm, a length of 20 mm, and a thickness (height) of 0.2 mm. In addition, one tobacco strand may be prepared to have a basis weight of 100g/m2 to 250g/m2, but is not limited thereto. Preferably, the tobacco strand can be made so that the basis weight is 180 g/m2.

Compared with the cigarette rod 3310 being filled with a cigarette sheet, a larger amount of aerosol may be generated in the cigarette rod 3310 filled with cigarette strands. Assuming that they are filled in the same space, compared to the tobacco sheet, the tobacco strands ensure a larger surface area. The large surface area means that there is more opportunity for the aerosol-generating material to contact the outside air. Thus, when the tobacco rod 3310 is filled with tobacco strands, more aerosols can be produced compared to that filled with tobacco sheets.

In addition, when separating the cigarette 3300 from the holder 3100, the cigarette rod 3310 filled with cigarette strands can be separated more easily than that filled with a cigarette sheet. In other words, when the cigarette rod 3310 is filled with cigarette strands, it can be more easily separated from the holder 3100 compared to being filled with a cigarette sheet.

The first filter segment 3321 may be a cellulose acetate filter. For example, the first filter segment 3321 may be a tube-shaped structure including a hollow inside. The length of the first filter segment 3321 may be an appropriate length within a range of 4 mm to 30 mm, but is not limited thereto. Preferably, the length of the first filter segment 3321 may be 10 mm, but is not limited thereto.

The diameter of the hollow included in the first filter segment 3321 may be an appropriate diameter within a range of 3 mm to 4.5 mm, but is not limited thereto.

The hardness of the first filter segment 3321 can be adjusted by adjusting the content of the plasticizer at the time of manufacture of the first filter segment 3321.

In order to prevent the size of the first filter segment 3321 from decreasing over time, the outer periphery of the first filter segment 3321 may be manufactured to be wrapped by a wrapper. Accordingly, the first filter segment 3321 can be easily combined with other configurations (eg, other filter segments).

Further, the first filter segment 3321 may be manufactured by inserting a structure such as a film or tube of the same or different material into the inside (eg, hollow).

The first filter segment 3321 may be manufactured using cellulose acetate. Accordingly, when the heater 3130 is inserted, the phenomenon in which the internal material of the cigarette rod 3310 is pushed back may be prevented, and a cooling effect of the aerosol may be generated.

The cooling structure 3322 cools the aerosol generated by the heater 3130 heating the tobacco rod 3310. Thus, the user can inhale the aerosol cooled to a suitable temperature.

The length or diameter of the cooling structure 3322 may be variously determined according to the shape of the cigarette 3300. For example, the length of the cooling structure 3322 can be suitably employed within a range of 7 mm to 20 mm. Preferably, the length of the cooling structure 3322 may be about 14 mm, but is not limited thereto.

The cooling structure 3322 may be made of pure polylactic acid or a combination of other degradable polymers and polylactic acid. For example, the cooling structure 3322 may be manufactured through an extrusion method or a textile weaving method. The cooling structure 3322 may be manufactured in various forms to increase the surface area per unit area (ie, the surface area in contact with the aerosol).

For example, the cooling structure 3322 can be produced by weaving fibers made of polylactic acid. In this case, a flavor liquid may be applied to the fibers made of polylactic acid. Alternatively, a cooling structure 3322 may be manufactured by using a separate fiber coated with a flavoring liquid and a fiber made of polylactic acid. In addition, the polylactic acid fiber may be dyed in a predetermined color, and the cooled structure 3322 may be manufactured using the dyed fiber.

Various examples of the cooling structure 3322 will be described later with reference to FIGS. 18A to 18F.

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, but is not limited thereto. The length of the second filter segment 3323 can be suitably employed within a range of 4 mm to 20 mm. For example, the length of the second filter segment 3323 may be about 12 mm, but is not limited thereto.

In the process of manufacturing the second filter segment 3323, the flavor may be produced by spraying a flavoring solution to the second filter segment 3323. Alternatively, a separate fiber coated with a flavoring liquid may be inserted into the second filter segment 3323. The aerosol generated in the tobacco rod 3310 is cooled as it passes through the cooling structure 3322, and the cooled aerosol is delivered to the user through the second filter segment 3323. Accordingly, when a flavoring element is added to the second filter segment 3323, an effect of enhancing the persistence of flavor delivered to the user may be generated.

Also, at least one capsule 3324 may be included in the second filter segment 3323. Here, the capsule 3324 may be a structure in which a content liquid containing a fragrance is wrapped with a film. For example, the capsule 3324 may have a spherical or cylindrical shape.

The film of capsule 3324 is also prepared by agar, pectin, sodium alginate, carrageenan, gelatin, or guar gum, etc. to form a film of capsule 3324. A curing aid may be further used as a material to be used. Here, as a gelling aid, a calcium chloride group etc. can be used, 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 can 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. may be used as a fragrance contained in the contents of the capsule. In addition, as a solvent of the fragrance contained in the content liquid, for example, a medium chain fatty acid triglyceride (MCT) may be used. In addition, the content liquid may contain other additives such as a pigment, emulsifier, and thickener.

18A to 18F are views showing examples of the cooling structure of the 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 a film (sheet) is produced by filling a film (sheet) and a cooling structure, 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, in the case of manufacturing a cooling structure by extrusion molding, the efficiency of the process is lowered as processes such as cutting of the structure are added. In addition, there are limitations in manufacturing cooling structures in various shapes.

As the cooling structure according to an embodiment is manufactured using polylactic acid fibers (for example, weaving), the risk that the cooling structure is deformed by an external impact or loses function may be lowered. In addition, by changing the method of combining the fibers, it is possible to manufacture a cooling structure having various shapes.

In addition, by fabricating a cooling structure using fibers, the surface area in contact with the aerosol is increased. Therefore, the aerosol cooling effect of the cooling structure can be further improved.

Referring to FIG. 18A, the cooling structure 6310 may be manufactured in a cylindrical shape, and at least one air passage 6311 may be formed on a cross section of the cooling structure 6310.

Referring to FIG. 18B, the cooling structure 6320 may be formed of a structure in which a plurality of fibers are entangled with each other. At this time, the aerosol may flow between fibers, and a vortex may be formed according to the shape of the cooling structure 6320. The formed vortex widens the area where the aerosol contacts in the cooling structure 6320, and increases the time that the aerosol stays in the cooling structure 6320. Thus, the heated aerosol can be cooled effectively.

Referring to FIG. 18C, the cooling structure 6330 may be manufactured in a form in which a plurality of bundles 631 are collected.

Referring to FIG. 18D, the cooling structure 6340 may be filled with granules made of polylactic acid, legume, or charcoal, respectively. In addition, the granules can also be made of a mixture of polylactic acid, legume and charcoal. On the other hand, the granule may further include an element capable of increasing the cooling effect of the aerosol in addition to polylactic acid, legume and/or charcoal.

Referring to FIG. 18E, the cooling structure 6350 may include a first section 6351 and a second section 6632.

The first cross-section 6351 borders the first filter segment 3321, and may include an air gap through which the aerosol flows. The second cross-section 6322 borders the second filter segment 3323 and may include voids through which aerosols can be released. For example, the first section 6351 and the second section 6632 may include a single pore having the same diameter, but the diameter and number of the voids included in the first section 6351 and the second section 6632 Is not limited to this.

In addition, the cooling structure 6350 may include a third cross section 6635 including a plurality of voids between the first cross section 6351 and the second cross section 6352. For example, the diameters of the plurality of voids included in the third section 6635 may be smaller than the diameters of the voids included in the first section 6351 and the second section 6632. In addition, the number of voids included in the third section 6635 may be greater than the number of voids included in the first section 6351 and the second section 6632.

Referring to FIG. 18F, the cooling structure 6360 may include a first cross-section 6301 that abuts the first filter segment 3321 and a second cross-section 6636 that abuts the second filter segment 3323. . Additionally, the cooling structure 6360 can include one or more tubular elements 6636. For example, the tubular element 6636 can penetrate the first end surface 6636 and the second end surface 6636. Further, the tubular element 6636 can be packaged in a microporous packaging material, and can be filled with a filler (eg, the granules described above with reference to FIG. 18D) that can increase the cooling effect of the aerosol.
