The present disclosure relates to an aerosol generating apparatus having a smoking restriction function, and a method, performed by the aerosol generating apparatus, of providing the smoking restriction function.
In existing smoking products, a method of generating aerosol by directly burning an aerosol generating material during use has been used. However, when an aerosol generating material is directly burned, unwanted volatile compounds are generated, and thus health problems may occur. Accordingly, recently various aerosol generating apparatuses have been developed that electrically heat rather than burn an aerosol generating material, while significantly reducing the generation of unwanted volatile compounds and providing the flavor of a cigarette unchanged.
Provided are an aerosol generating apparatus having a smoking restriction function, and a method, performed by the aerosol generating apparatus, of providing the smoking restriction function. Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments.
According to an aspect of the present disclosure, an aerosol generating apparatus includes a memory storing data about a smoking pattern of a user; an interface configured to receive a smoking initiation request from the user; a controller configured to determine whether the received smoking initiation request satisfies a smoking restriction condition for restricting smoking, based on the data about the smoking pattern; and a heater that receives, from a battery, power for generating aerosol or is restricted in terms of supply of the power under the control of the controller, according to whether the smoking restriction condition is satisfied.
According to another aspect of the present disclosure, a method of providing a smoking restriction function in an aerosol generating apparatus includes monitoring a smoking pattern of a user; receiving a smoking initiation request from the user; determining whether the received smoking initiation request satisfies a smoking restriction condition for restricting smoking, based on the monitoring of the smoking pattern; and controlling a heater to receive, from a battery, power for generating aerosol or to be restricted in terms of supply of the power, according to whether the smoking restriction condition is satisfied
According to the above descriptions, a smoking behavior of a user may be appropriately controlled by using data about a smoking pattern of the user.
According to an aspect of the present disclosure, there is provided an aerosol generating apparatus including: a memory storing data about a smoking pattern of a user; an interface configured to receive a smoking initiation request from the user; a controller configured to determine whether the received smoking initiation request satisfies a smoking restriction condition for restricting smoking, based on the data about the smoking pattern; and a heater that receives, from a battery, power for generating aerosol or is restricted in terms of supply of the power under the control of the controller, according to whether the smoking restriction condition is satisfied.

Terms arbitrarily selected by the applicant of the disclosure may also be used in a specific case. In this case, their meanings need to be given in the detailed description. Hence, the terms must be defined based on their meanings and the contents of the entire specification, not by simply stating the terms.
Throughout the specification, when an element is referred to as being “connected” or “coupled” to another element, it can be directly connected or coupled to the other element, or can be electrically connected or coupled to the other element with intervening elements interposed therebetween.

For example, the solid aerosol generating material may include a solid material based on a tobacco raw material, such as a tobacco sheet, shredded tobacco, reconstituted tobacco, etc., and the liquid aerosol generating material may include a liquid material based on nicotine, tobacco extract and various flavoring agents. Of course, embodiments are not limited thereto.
In embodiments below, an aerosol generating apparatus may be an apparatus that generates aerosol by using an aerosol generating material to generate aerosol capable of being directly inhaled into the user's lung through the user's mouth.

The aerosol generating apparatus 1 includes a heater 10 that is electrically heated by power supplied by a battery. The heater 10 is fixed to be located within an empty space (or cavity) 100 formed on one end of the aerosol generating apparatus 1. A cigarette 3 may be accommodated in the empty space 100 of the aerosol generating apparatus 1. When the cigarette 3 is accommodated in the empty space 100, the heater 10 may penetrate through the aerosol generating material 21 provided on one end of the cigarette 3. The cigarette 3 may be used as various terms, such as a tobacco and a heat stick. The cigarette 3 is a smoking product including the aerosol generating material 21 packaged on an end and a filter 22 provided on the other end. The aerosol generating material 21 and the filter 22 are surrounded by a wrapper to contact each other.
When the cigarette 3 is inserted into the empty space 100 of the aerosol generating apparatus 1, the aerosol generating apparatus 1 heats the heater 10. The temperature of the aerosol generating material 21 in the cigarette 3 is raised by the heated heater 10, and thus aerosol is generated. The generated aerosol may be transferred to the user via the filter 22 of the cigarette 3. The heater 10 heats the aerosol generating material 21 to a temperature where the aerosol generating material 2 is not combusted.
The heater 10 is electrically heated by the power supplied by the battery. The heater 10 of

The heater 10 may be electrically heated by power supplied by the battery 110 under the control of the controller 120. The heater 10 may be an electro-resistive heater. For example, the heater 10 includes an electrically conductive track, and the heater 10 may be heated as a current flows through the electrically conductive track. When power is supplied to the heater 10, the surface temperature of the heater 10 may rise to 400° C. or higher. The surface temperature of the heater 10 may rise to about 350° C. before a certain time period (e.g., 15 seconds) after the power starts being supplied to the heater 10 starts.
The controller 120 is hardware that controls all operations of the aerosol generating apparatus 1. The controller 120 is an integrated circuit implemented by using a processing unit such as a microprocessor or a microcontroller.
The controller 120 analyzes a result of the sensing by the sensor 130, and controls processes that are to be performed subsequently. The controller 120 may resume or interrupt supply of power from the battery 110 to the heater 10, according to the result of the sensing. The controller 120 may control the amount of power supplied to the heater 10 and a time period during which power is supplied, such that the heater 10 may be heated to a predetermined temperature or maintained at a proper temperature. Furthermore, the controller 120 may process various pieces of input information and output information of the interface 140.
The controller 120 may count the number of times a user smokes by using the aerosol generating apparatus 1, and may control related functions of the aerosol generating apparatus 1 to restrict smoking of the user according to a result of the counting. This will be described in more detail later with corresponding drawings below.
The memory 115 may store data about a smoking pattern of the user, such as a smoking time and the number of times of smoking. The memory 115 is hardware for storing various kinds of data processed in the aerosol generating apparatus 1. For example, the memory 115 may store data that have been processed and are to be processed in the controller 120. The memory 115 may be implemented by using any of various types such as random access memory (RAM) (e.g., dynamic random access memory (DRAM) and static random access memory (SRAM)), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM).
The battery 110 supplies power used for the aerosol generating apparatus 1 to operate. In other words, the battery 110 may supply power such that the heater 10 may be heated. The battery 110 may also supply power necessary for respective operations of the other hardware components included in the aerosol generating apparatus 1, for example, the controller 120, the sensor 130, and the interface 140. The battery 110 may be a lithium iron phosphate (LiFePO4) battery, but embodiments are not limited thereto. The battery 110 may be manufactured as a lithium cobalt oxide (LiCoO2) battery, a lithium titanate battery, or the like. The battery 110 may be a rechargeable battery or a disposable battery.
The sensor 130 may include various types of sensors such as a puff detection sensor (e.g., a temperature detection sensor or a flow detection sensor), and a cigarette detection sensor. The puff detection sensor may be implemented by using a pressure sensor or the like. The cigarette detection sensor may be implemented by using a capacitive sensor or a resistive sensor. The result of the sensing by the sensor 130 may be transferred to the controller 120. According to the result of the sensing, the controller 120 may control the aerosol generating apparatus 1 such that various functions such as heater temperature control, smoking restriction, and notification display may be performed.
The interface 140 may include various interfacing means such as a display or lamp for outputting visual information, a motor for outputting tactile information, a speaker for outputting sound information, input/output (I/O) interfacing means (for example, a button or a touch screen) for receiving information input by a user or outputting information to the user, terminals for communicating with a cradle (or referred to as a cradle device) through data or receiving charging power from the cradle, and a communication interfacing module for performing wireless communication (for example, WI-FI, WI-FI Direct, Bluetooth, or Near-Field Communication (NFC)) with an external device. However, the aerosol generating apparatus 1 may be implemented by selecting only some of the aforementioned various interfacing means.

Referring to
The sensor 130 of the aerosol generating apparatus 1 may sense a start and an end of smoking by sensing insertion and extraction of the cigarette 3 or sensing a change in a heater temperature. Accordingly, the controller 120 may count the completion of one-time smoking, while determining a time when one-time smoking is completed, based on the result of the sensing. The controller 120 may check a smoking time and count the number of times a user smokes, based on a power on/off signal of the aerosol generating apparatus 1 due to an input of a button of the interface 140. The memory 115 may store cumulative information about the smoking time points and the numbers of times a user smokes. However, various other methods and criteria by which the aerosol generating apparatus 1 determines one time smoking may be employed.
In the illustration of
Referring to the table 400, because the user smoked 9 times in total on Monday, the smoking restriction function of the aerosol generating apparatus 1 was not activated. The user smoked 10 times in total on Tuesday, and eleventh smoking and twelfth smoking after tenth smoking were not properly performed due to the smoking restriction function of the aerosol generating apparatus 1. The user smoked 10 times in total on Wednesday, and two smoking trials between eighth smoking and tenth smoking were restricted due to the smoking restriction function, and eleventh smoking was also restricted. As such, the controller 120 of the aerosol generating apparatus 1 may accumulate and count the number of times the user smokes. When set smoking restriction conditions are satisfied, smoking of the user may be restricted by activating the smoking restriction function of the aerosol generating apparatus 1.
According to the smoking pattern from Thursday to Saturday shown in the table 400, similar to the smoking pattern from Tuesday to Wednesday, when the set smoking restriction conditions are satisfied, smoking of the user was restricted by the smoking restriction function of the aerosol generating apparatus 1.
The controller 120 of the aerosol generating apparatus 1 may determine whether the set smoking restriction conditions are satisfied, based on whether the number of times the user smokes during a preset threshold time period has reached a preset threshold number of times.
Furthermore, the aerosol generating apparatus 1 may restrict smoking trials after a set smoking restriction number of times is exceeded, and may also restrict adjacent smoking trials within a set smoking restriction time interval. However, because various smoking restriction conditions to be applied to the aerosol generating apparatus 1 may be set as described above, smoking may be restricted under the various smoking restriction conditions.
Referring to
One time smoking may be counted as being completed when the user puffs the cigarette 3 a plurality of times. For example, one time smoking may be determined to be completed when the user puffs the cigarette 3 inserted into the aerosol generating apparatus 1 about 14 times. In other words, according to an embodiment, the controller 120 of the aerosol generating apparatus 1 may determine a start and an end of smoking, based on a puffing number of times corresponding to a change in the heater temperature, and may count the number of times the user smokes by determining that one time smoking has ended when the user puffs the cigarette 3 a preset threshold puffing number of times.
According to another embodiment, the aerosol generating apparatus 1 may count the number of times the user smokes, by determining a start and an end of smoking by using criteria other than the heater temperature.
For example, the sensor 130 of the aerosol generating apparatus 1 may be implemented to include a cigarette detection sensor. The controller 120 may determine that smoking has started, when the cigarette detection sensor senses that the cigarette 3 was inserted, and then may determine that smoking has ended, when the cigarette detection sensor senses that the cigarette 3 was extracted. In other words, the aerosol generating apparatus 1 may count one time smoking, based on a result of sensing the insertion and extraction of the cigarette 3.
The sensor 130 of the aerosol generating apparatus 1 may be implemented to include a flow detection sensor. Because external air flows into the aerosol generating apparatus 1 during user puffing and thus a flow rate within the aerosol generating apparatus 1 increases, the flow rate within the aerosol generating apparatus 1 may vary during every user puffing. Thus, the controller 120 of the aerosol generating apparatus 1 may determine a start and an end of smoking, based on a puffing number of times corresponding to a change in the flow rate, and may count the number of times the user smokes by determining that one time smoking has ended when the user puffs the cigarette 3 a preset threshold puffing number of times.
In addition, the aerosol generating apparatus 1 may count the number of times the user smokes, based on a button input via the interface 140.
Finally, the controller 120 of the aerosol generating apparatus 1 may count the number of times the user smokes, by determining a start and an end of smoking according to various methods such as a button input via the interface 140, sensing of cigarette insertion and extraction, sensing of puffing due to a change in the heater temperature, and sensing of puffing due to a change in the flow rate.
The aerosol generating apparatus 1 may restrict smoking of the user by activating the smoking restriction function when the smoking restriction conditions are satisfied, while monitoring a result of counting the number of times the user smokes according to any of the above-described methods and information about a smoking-completion time point as in the table 400 of
According to whether the smoking restriction condition is satisfied, the heater 10 may receive power for generating aerosol from the battery or supply of power to the heater 10 may be restricted, under the control of the controller 120. The aerosol generating apparatus 1 may execute various smoking restriction functions in the smoking restriction mode.
In an example of the smoking restriction function, as shown in the heater temperature variation graph 602, in the smoking restriction mode, the controller 120 may control the temperature of the heater 10 to be lower than a temperature range that is controlled in the smoking mode. In other words, in the smoking restriction mode where the smoking restriction condition is satisfied, the controller 120 may restrict power supply to the heater 10 to control the heater 10 in a low temperate range compared with the temperature range of the heater 10 that is controlled in the smoking mode where the smoking restriction condition is not satisfied. Accordingly, in the aerosol generating apparatus 1, only a relatively small amount of aerosol is generated. In other words, the low temperature range may mean a temperature range that enables the amount of aerosol generated by heating of the heater 10 in the smoking restriction mode to be less than the amount of aerosol generated by heating of the heater 10 in the smoking mode. Accordingly, the user merely inhale a small amount of aerosol even when the user puffs the cigarette 3, and thus the user may feel significantly reduced smoking compared with in the smoking mode. Consequently, smoking of the user may be restricted.
Meanwhile, the low temperature range in the smoking restriction mode may also mean a temperature range that is controlled within a section 510 maintained at a constant range of temperature to generate aerosol after preheating of the heater 10. However, embodiments are not limited thereto, and the low temperature range in the smoking restriction mode may mean a temperature range changing during the entire section ranging from the preheating of the heater 10 to cooling of the heater 10, or may mean a temperature range of any of various partial sections of the entire section. A temperature value controlled to be low may vary according to settings in the aerosol generating apparatus 1.
In another example of the smoking restriction function, in the smoking restriction mode, the controller 120 may deactivate the heater 10 so that, even when the cigarette 3 is inserted into the aerosol generating apparatus 1, the temperature of the heater 10 does not rise. Thus, no aerosol is generated in the aerosol generating apparatus 1, and accordingly the user may not feel smoking. Consequently, smoking of the user may be restricted.

According to {circle around (1)} method 701, when the interface 140 of the aerosol generating apparatus 1 is implemented to include a display 143, the display 143 may display a symbol informing the user that the smoking restriction function of the aerosol generating apparatus 1 is currently activated according to the smoking restriction mode.
According to {circle around (2)} method 702, when the interface 140 of the aerosol generating apparatus 1 is implemented to include a lamp (for example, an LED lamp), the lamp may, for example, change its color or flicker in order to inform the user that the smoking restriction function of the aerosol generating apparatus 1 is currently activated according to the smoking restriction mode.
According to {circle around (3)} method 703, when the interface 140 of the aerosol generating apparatus 1 is implemented to include a speaker, the speaker may output a sound to inform the user that the smoking restriction function of the aerosol generating apparatus 1 is currently activated according to the smoking restriction mode.
According to {circle around (4)} method 704, when the interface 140 of the aerosol generating apparatus 1 is implemented to include a motor, the motor may generate a vibration to inform the user that the smoking restriction function of the aerosol generating apparatus 1 is currently activated according to the smoking restriction mode.
In the smoking restriction mode where the smoking restriction condition is satisfied, the interface 140 may provide a notification indicating that the smoking restriction mode has been activated, by using an interfacing means such as the display 143, the lamp, the speaker, or the motor vibration. The aerosol generating apparatus 1 may also provide the user with a notification of the smoking restriction mode by using any of various methods according to different types of hardware components included in the interface 140.

The items of the smoking restriction condition may include a threshold number, a threshold period, and the like. For example, the display 143 may display an image 1000 on which a threshold number, a threshold period, and the like may be set via scrolling, and the user may set smoking restriction condition items such as a desired threshold number, a desired threshold period, and the like by scrolling the image 1000 via an input of the button 141.
Referring to
First, whether to use the smoking restriction mode in the aerosol generating apparatus 1 may be set via the electronic cigarette app 1100. If the smoking restriction mode is not used, the aerosol generating apparatus 1 is able to perform smoking regardless of the number of times the user smokes.
A threshold period may be set as one of the smoking restriction conditions. The threshold period means a period to restrict the number of times the user smokes. The threshold period may be set on the basis of one day, one week, and one month, or set for any of various other periods such as a specific day of the week and a specific time zone. Furthermore, the starting point of reckoning the threshold period may be set.
A threshold number may be set as another of the smoking restriction conditions. When smoking occurs a set threshold number of times within a set threshold period, subsequent smoking trials may be restricted. As for the threshold number, a total smoking number of times may be set or a total puffing number of times may be set. As described above, one time smoking may be counted as being completed when the user puffs the cigarette 3 a plurality of times (e.g., 14 times).
A consecutive smoking restriction period may be set as another of the smoking restriction conditions. Because the aerosol generating apparatus 1 electrically heats the heater 10, when consecutive smoking actions may be tried within a short period of time, lifespans of the heater 10 and the aerosol generating apparatus 1 may be reduced. In other words, after heating of the heater 10 for smoking, a desirable cooling time period may be needed. Consecutive smoking actions within a short period of time are harmful to the health of the user. Accordingly, smoking of the user may be restricted within the consecutive smoking restriction period set as another of the smoking restriction conditions. Referring back to
A method of informing activation of the smoking restriction mode may be set via the electronic cigarette app 1100. For example, at least one of the methods described above with reference to

The cradle 2 may be wiredly connected to an external device 1200 via a cable. When the aerosol generating apparatus 1 is coupled with the cradle 2 and is connected to an external device 1200 by wire, a user may execute an electronic cigarette app 1210 in the external device 1200 and input settings regarding the aerosol generating apparatus 1. The settings regarding the aerosol generating apparatus 1 may include the various settings described above with reference to
When various settings have been completed via the electronic cigarette app 1210 executed in the external device 1200, the external device 1200 may transmit setting information input by the electronic cigarette app 1210 to the cradle 2 via wired communication. The cradle 2 may transmit the setting information to the aerosol generating apparatus 1 via a communication terminal in contact with the aerosol generating apparatus 1, and the aerosol generating apparatus 1 may operate according to the received setting information.
Finally, the smoking restriction conditions may be based on setting information input via the interface 140, setting information received from the external device 900 via wireless communication, and setting information received from the external device 1200 via wired communication when the external device 1200 is coupled with the cradle 2.

In operation 1301, the aerosol generating apparatus 1 receives a smoking initiation request from a user. A determination as to whether the smoking initiation request exists may be based on a determination by the controller 120 as to whether there is an input via the interface 140 of the aerosol generating apparatus 1 or results of detection of cigarette insertion by the sensor 130 and sensing of a change in a heater temperature.
In operation 1302, the controller 120 determines whether the smoking initiation request satisfies a smoking restriction condition for restricting smoking, based on data about a smoking pattern stored in the memory 115. In detail, the controller 120 determines whether a smoking number counted up to a current time has reached a threshold number. When it is determined that the smoking number counted up to a current time has reached the threshold number, the controller 120 activate the smoking restriction mode and performs operation 1303. On the other hand, when it is determined that the smoking number counted up to a current time has not reached the threshold number, the controller 120 performs operation 1307 according to the smoking mode.
In operation 1303, the controller 120 determines whether to deactivate the heater 10 in the smoking restriction mode.
In operation 1304, the controller 120 controls the temperature of the heater 10 to be lower than a temperature range of the heater 10 that is controlled in the smoking mode, thereby restricting smoking of the user.
In operation 1305, the controller 120 deactivates the heater 10 to thereby restricting smoking of the user.
In operation 1306, the interface 140 informs the user that the smoking restriction function has been activated, via a display, a lamp, a speaker, vibration of a motor, or the like.
In operation 1307, the controller 120 controls the heater 10 to a temperature where aerosol may be normally generated, according to the smoking mode.

Only components related with the present embodiment from among the components of the holder 1 are shown in
When a cigarette is inserted into the holder 1, the holder 1 heats the heater 2130. The temperature of an aerosol generating material in the cigarette is raised by the heated heater 2130, and thus aerosol is generated. The generated aerosol is delivered to a user through a cigarette filter. However, even when a cigarette is not inserted into the holder 1, the holder 1 may heat the heater 2130.
The casing 2140 may be detached from the holder 1. For example, when a user rotates the casing 2140 clockwise or counterclockwise, the casing 2140 may be detached from the holder 1.
The diameter of a hole formed by a terminal end 2141 of the casing 2140 may be smaller than the diameter of a space formed by the casing 2140 and the heater 2130. In this case, the hole may serve as a guide for a cigarette inserted into the holder 1.
The battery 110 supplies power used for the holder 1 to operate. For example, the battery 110 may supply power for heating the heater 2130 and supply power for operating the control unit 120. In addition, the battery 110 may supply power for operating a display, a sensor, a motor, and the like installed in the holder 1.
The battery 110 may be a lithium iron phosphate (LiFePO4) battery, but is not limited to the example described above. For example, the battery 110 may be a lithium cobalt oxide (LiCoO2) battery, a lithium titanate battery, etc.
Also, 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 the battery 110 may be a rechargeable battery or a disposable battery. For example, when the battery 110 is rechargeable, the charging rate (C-rate) of the battery 110 may be 10C and the discharging rate (C-rate) may be 16C to 20C. However, the present disclosure is not limited thereto. Also, for stable use, the battery 110 may be manufactured, such that 80% or more of the total capacity may be ensured even when charging/discharging are performed 8000 times.
Here, it may be determined whether the battery 110 is fully charged or completely discharged based on a level of power stored in the battery 110 as compared to the entire capacity of the battery 110. For example, when the power stored in the battery 110 is equal to or more than 95% of the total capacity, it may be determined that the battery 110 is fully charged. Furthermore, 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 criteria for determining whether the battery 110 is fully charged or completely discharged are not limited to the above examples.
The heater 2130 is heated by power supplied from the battery 110. When a cigarette is inserted into the holder 1, the heater 2130 is located inside the cigarette. Therefore, the heated heater 2130 may raise the temperature of the aerosol generating material in the cigarette.
The shape of the heater 2130 may be a combination of a cylindrical shape and a conical shape. 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 a terminal end 2131 of the heater 2130 may be formed to have an acute angle, but is not limited thereto. In other words, the heater 2130 may have any shape as long as the heater 2130 may be inserted into the cigarette. In addition, only a portion 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 terminal 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 electro-resistive heater. For example, the heater 2130 includes an electrically conductive track, and the heater 2130 may be heated as a current flows through the electrically conductive track.
For stable use, the heater 2130 may be supplied with power according to specifications of 3.2 V, 2.4 A, and 8 W, but is not limited thereto. For example, when power is supplied to the heater 2130, the surface temperature of the heater 2130 may rise to 400° C. or higher. The surface temperature of the heater 2130 may rise to about 350° C. before 15 seconds after the power supply to the heater 2130 starts.
The holder 1 may be provided with a separate temperature sensor. Alternatively, the holder 1 may not be provided with a temperature sensor, 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 a first electrically conductive track for generating heat.
For example, when a voltage applied to the second electrically conductive track and a current flowing through the second electrically conductive track are measured, a resistance R may be determined. At this time, a temperature T of the second electrically conductive track may be determined by Equation 1 below.
R=R
0{1+α(T−T0)} [Equation 1]
In Equation 1, R denotes a current resistance value of the second electrically conductive track, R0 denotes a resistance value at a temperature T0 (e.g., 0° C.), and a denotes a resistance temperature coefficient of the second electrically conductive track. Because conductive materials (e.g., metals) have inherent resistance temperature coefficients, a may be determined in advance according to a 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 may be calculated according to Equation 1.
The heater 2130 may include at least one electrically conductive track (a first electrically conductive track and a second electrically conductive track). For example, the heater 2130 may include, but is not limited to, two first electrically conductive tracks and one or two second electrically conductive tracks.
An electrically conductive track includes an electro-resistive material. For example, an electrically conductive track may include a metal. In another example, an electrically conductive track may include an electrically conductive ceramic material, carbon, a metal alloy, or a composite of a ceramic material and a metal.
In addition, the holder 1 may include both an electrically conductive track, which serves as temperature sensors, and a temperature sensor.
The control unit 120 controls the overall operation of the holder 1. In detail, the control unit 120 controls not only operations of the battery 110 and the heater 2130, but also operations of other components included in the holder 1. The control unit 120 may also check the status of each of the components of the holder 1 and determine whether the holder 1 is in an operable state.
The control unit 120 includes at least one processor. A processor may be implemented by an array of a plurality of logic gates, or by a combination of a general-use microprocessor and a memory in which a program executable by the general-use microprocessor is stored. It will also be understood by one of ordinary skill in the art to which this embodiment pertains that the central processor may be implemented by other types of hardware.
For example, the control unit 120 may control the operation of the heater 2130. The control unit 120 may control an amount of power supplied to the heater 2130 and a time period for supplying the power, such that the heater 2130 may be heated to a predetermined temperature or maintained at a proper temperature. The control unit 120 may also check the status of the battery 110 (e.g., the remaining amount of the battery 110) and generate a notification signal as occasions demand.
Also, the control unit 120 may check the presence or absence of a user's puff, check the strength of the puff, and count the number of puffs. Also, the control unit 120 may continuously check the time period during which the holder 1 is operating. The control unit 120 may also check whether a cradle 2 to be described below is coupled with the holder 1, and control the operation of the holder 1 according to whether the cradle 2 is coupled with or separated from the holder 1.
Meanwhile, the holder 1 may further include general-purpose components other than the battery 110, the control unit 120, and the heater 2130.
For example, the holder 1 may include a display capable of outputting visual information or a motor for outputting tactile information. For example, when a display is included in the holder 1, the control unit 120 may provide the user with information about the state of the holder 1 (e.g., availability on unavailability of the holder, etc.), information about the heater 2130 (e.g., start of preheating, progress of preheating, completion of preheating, etc.), information about the battery 110 (e.g., remaining power of the battery 110, availability on unavailability, etc.), information about resetting of the holder 1 (e.g., reset timing, reset progress, reset completion, etc.), information about cleaning of the holder 1 (e.g., cleaning timing, necessity of cleaning, cleaning progress, cleaning completion, etc.), information about charging of the holder 1 (e.g., necessity of charging, charging progress, charging completed, etc.), information about puffs (e.g., the number of puffs, notification of expected completion of puffs, etc.), or information about safety (e.g., the lapse of time of use, etc.) via the display. In another example, when a motor is included in the holder 1, the control unit 120 may transmit the above-described information to the user by generating a vibration signal by using the motor.
The holder 1 may also include a terminal coupled with at least one input device (e.g., a button) and/or the cradle 2 through which a user may control the function of the holder 1. For example, a user may perform various functions by using the input device of the holder 1. By adjusting the number of times a user presses the input device (e.g., once, twice, etc.) or the time during which the input device is being pressed (e.g., 0.1 second, 0.2 second, etc.), a desired function from among a plurality of functions of the holder 1 may be executed. As a user manipulates the input device, the holder 1 may perform a function of preheating the heater 2130, a function of regulating the temperature of the heater 2130, a function of cleaning the space in which a cigarette is inserted, a function of checking whether the holder 1 is in an operable state, a function of displaying the remaining power (available power) of the battery 110, a function of resetting the holder 1, etc. However, the functions of the holder 1 are not limited to the examples described above.
The holder 1 may also include a puff detecting sensor, a temperature detecting sensor, and/or a cigarette insertion detecting sensor. For example, the puff detecting sensor may be implemented by a common pressure sensor, and the cigarette insertion detecting sensor may be implemented by a common capacitive sensor or a resistance sensor. Also, the holder 1 may be fabricated to have a structure in which the outside air may flow in/out even in the state where the cigarette is inserted.

Only components related with the present embodiment from among the components of the cradle 2 are shown in
The battery 210 provides power used to operate the cradle 2. In addition, the battery 210 may supply power for charging the battery 110 of the holder 1. For example, when the holder 1 is inserted into the cradle 2 and the terminal 2170 of the holder 1 is coupled with the terminal 2260 of the cradle 2, the battery 210 of the cradle 2 may supply power to the battery 110 of the holder 1.
Also, when the holder 1 is coupled with the cradle 2, the battery 210 may supply power used for the holder 1 to operate. For example, when the terminal 2170 of the holder 1 is coupled with the terminal 2260 of the cradle 2, the holder 1 may operate by using power supplied by the battery 210 of the cradle 2 regardless of whether the battery 110 of the holder 1 is discharged or not.
An example of the type of the battery 210 may be the same as that of the type of the battery 110 described above with reference to
The control unit 220 controls the overall operation of the cradle 2. The control unit 220 may control the operations of all the configurations of the cradle 2. The control unit 220 may also determine whether the holder 1 is coupled with the cradle 2 and control the operation of the cradle 2 according to coupling or separation of the cradle 2 and the holder 1.
For example, when the holder 1 is coupled with the cradle 2, the control unit 220 may supply power of the battery 210 to the holder 1, thereby charging the battery 110 or heating the heater 2130. Therefore, even when remaining power of the battery 110 is low, a user may continuously smoke by coupling the holder 1 with the cradle 2.
The control unit 220 includes at least one processor. A processor may be implemented by an array of a plurality of logic gates, or by a combination of a general-use microprocessor and a memory in which a program executable by the general-use microprocessor is stored. It will also be understood by one of ordinary skill in the art to which this example pertains that the central processor may be implemented by other types of hardware.
Meanwhile, the cradle 2 may further include general-purpose components other than the battery 210 and the control unit 220. For example, the cradle 2 may include a display capable of outputting visual information. For example, when the cradle 2 includes a display, the control unit 220 generates a signal to be displayed on the display, thereby informing a user of information regarding the battery 210 (e.g., the remaining power of the battery 210, availability or unavailability of the battery 210, etc.), information regarding resetting of the cradle 2 (e.g., reset timing, reset progress, reset completion, etc.), information regarding cleaning of the holder 1 (e.g., cleaning timing, cleaning necessity, cleaning progress, cleaning completion, etc.), and information regarding charging of the cradle 2 (e.g., charging necessity, charging progress, charging completion, etc.).
The cradle 2 may also include at least one input device (e.g., a button) for a user to control the function of the cradle 2, a terminal 260 to be coupled with the holder 1, and/or an interface for charging the battery 210 (e.g., an USB port, etc.).
For example, a user may perform various functions by using the input device of the cradle 2. By controlling the number of times that a user presses the input device or a period of time during which the input device is being pressed, a desired function from among the plurality of functions of the cradle 2 may be executed. As a user manipulates the input device, the cradle 2 may perform a function of preheating the heater 2130 of the holder 1, a function of regulating the temperature of the heater 2130 of the holder 1, a function of cleaning the space within the holder 1 in which a cigarette is inserted, a function of checking whether the cradle 2 is in an operable state, a function of displaying the remaining power (available power) of the battery 210 of the cradle 2, a function of resetting the cradle 2, etc. However, the functions of the cradle 2 are not limited to the examples described above.
As described above, the holder 1 may be inserted into the inner space 2230 of the cradle 2. The holder 1 may be completely inserted into the cradle 2 or may be tilted while being inserted into the cradle 2. Hereinafter, examples in which the holder 1 is inserted into the cradle 2 will be described below.
Referring to
The cradle 2 may include at least one attaching member, namely, attaching members 2271 and 2272, to increase attachment strength with the holder 1. Also, at least one attaching member 2181 may be included in the holder 1. Here, the attaching members 2181, 2271, and 2272 may be magnets, but are not limited thereto. Although
The holder 1 may include the attaching member 2181 at a first position, and the cradle 2 may include the attaching members 2271 and 2272 at 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.
Since the attaching members 2181, 2271, and 2272 are included in the holder 1 and the cradle 2, the holder 1 and the cradle 2 may be attached to each other more strongly even when the holder 1 is inserted into one side surface of the cradle 2. In other words, as the holder 1 and the cradle 2 further include the attaching members 2181, 2271, and 2272 in addition to the terminals 2170 and 2260, the holder 1 and the cradle 2 may be attached to each other more strongly. Therefore, even when there is no separate component (e.g., a lid) in the cradle 2, the inserted holder 1 may not be easily separated from the cradle 2.
Also, when the control unit 220 also determines that the holder 1 has been completely inserted into the cradle 2 through the terminals 2170 and 2260 and/or the attaching members 2181, 2271, and 2272, the control unit 220 may charge the battery 110 of the holder 1 by using the power of the battery 210.
Referring to
As shown in
As shown in
Also, even when the holder 1 is tilted, the terminal 2170 of the holder 1 and the terminal 2260 of the cradle 2 are coupled with each other. Therefore, the heater 2130 of the holder 1 may be heated by power supplied by the battery 210 of the cradle 2. Therefore, the holder 1 may generate aerosol by using the battery 210 of the cradle 2 even when the remaining power of the battery 110 of the holder 1 is low or the battery 110 of the holder 1 is completely discharged.
Also, when the control unit 220 also determines that the holder 1 has been tilted by the terminals 2170 and 2260 and/or the attaching members 2182, 2273, and 2274, the control unit 220 may heat the heater 2130 of the holder 1 or charge the battery 110 by using the power of the battery 210.
A method of generating aerosols shown in
In operation 2710, the holder 1 determines whether it is inserted into the cradle 2. For example, the control unit 120 may determine whether the holder 1 is inserted into the cradle 2, based on whether the terminals 2170 and 2260 of the holder 1 and the cradle 2 are connected to each other and/or whether the attaching members 2181, 2271, and 2272 are operating.
When the holder 1 has been inserted into the cradle 2, the method proceeds to operation 2720. When the holder 1 has been separated from the cradle 2, the method proceeds to operation 2730.
In operation 2720, the cradle 2 determines whether the holder 1 is tilted. For example, the control unit 220 may determine whether the holder 1 is tilted, based on whether the terminals 2170 and 2260 of the holder 1 and the cradle 2 are connected to each other and/or whether the attaching members 2182, 2273, and 2274 are operating.
Although it is described that the cradle 2 determines whether the holder 1 is tilted in operation 2720, the present disclosure is not limited thereto. In other words, the control unit 120 of the holder 1 may determine whether the holder 1 is tilted.
When the holder 1 is tilted, the method proceeds to operation 2740. When the holder 1 is not tilted (i.e., when the holder 1 is completely inserted into the cradle 2), the method proceeds to operation 2770.
In operation 2730, the holder 1 determines whether conditions of using the holder 1 are satisfied. For example, the control unit 120 may determine whether the conditions for using the holder 1 are satisfied, by checking the remaining power of the battery 110 and checking whether other components of the holder 1 may be normally operated.
When the conditions for using the holder 1 are satisfied, the method proceeds to operation 2740. Otherwise, the method is terminated.
In operation 2740, the holder 1 informs a user that the holder 1 is ready to be used. For example, the control unit 120 may output an image indicating that the holder 1 is ready to be used on the display of the holder 1, or may control the motor of the holder 1 to generate a vibration signal.
In operation 2750, the heater 2130 is heated. For example, when the holder 1 is separated from the cradle 2, the heater 2130 may be heated by power of the battery 110 of the holder 1. In another example, when the holder 1 is tilted, the heater 2130 may be heated by power of the battery 210 of the cradle 2.
The control unit 120 of the holder 1 or the control unit 220 of the cradle 2 may check the temperature of the heater 2130 in real time and control an amount of power supplied to the heater 2130 and a time period for supplying the power to the heater 2130. For example, the control unit 120 or 220 may check the temperature of the heater 2130 in real time through a temperature sensor included in the holder 1 or an electrically conductive track of the heater 2130.
In operation 2760, the holder 1 performs an aerosol generation mechanism. For example, the control unit 120 or 220 may check the temperature of the heater 2130, which changes as a user performs puffs, and adjust an amount of power supplied to the heater 2130 or stop supplying power to the heater 2130. Also, the control unit 120 or 220 may count the number of puffs of the user, and output information indicating that the holder 1 needs to be cleaned when the number of puffs reaches a certain number of times (e.g., 1500 times).
In operation 2770, the cradle 2 performs charging of the holder 1. For example, the control unit 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 control unit 120 or 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
A method of generating aerosols shown in
In operation 2810, the control unit 120 or 220 determines whether a user puffed. For example, the control unit 120 or 220 may determine whether the user puffed through the puff detecting sensor included in the holder 1.
In operation 2820, aerosol is generated according to the puff of the user. The control unit 120 or 220 may adjust power supplied to the heater 2130 according to the puff of the user and the temperature of the heater 2130, as described above with reference to
In operation 2830, the control unit 120 or 220 determines whether the number of puffs of the user is equal to or greater than a puff limit number. For example, assuming that the puff limit number is set to 14 times, the control unit 120 or 220 determines whether the number of counted puffs is 14 times or more.
When the number of puffs of the user is close to the puff limit number (e.g., when the number of puffs of the user is 12), the control unit 120 or 220 may output a warning signal through a display or a vibration motor.
When the number of puffs of the user is equal to or greater than the puff limit number, the method proceeds to operation 2850. When the number of puffs of the user is less than the puff limit number, the method proceeds to operation 2840.
In operation 2840, the control unit 120 or 220 determines whether the operation time of the holder 1 is equal to or greater than an operation limit time. Here, the operation time of the holder 1 refers to an accumulated time from a time point at which the holder 1 started its operation to a current time point. For example, assuming that the operation limit time is set to 10 minutes, the control unit 120 or 220 determines whether the holder 1 is operating for 10 minutes or longer.
When the operation time of the holder 1 is close to the operation limit time (e.g., when the holder 1 is operating for 8 minutes), the control unit 120 or 220 may output a warning signal through a display or a vibration motor.
When the holder 1 is operating for the operation limit time or longer, the method proceeds to operation 2850. When the operation time of the holder 1 is less than the operation limit time, the method proceeds to operation 2820.
In operation 2850, the control unit 120 or 220 forcibly terminates the operation of the holder 1. In other words, the control unit 120 or 220 terminates the aerosol generation mechanism of the holder 1. For example, the control unit 120 or 220 may forcibly terminate the operation of the holder 1 by interrupting the power supplied to the heater 2130.
The flowchart shown in
Although not shown in
In operation 2910, the control unit 220 of the cradle 2 determines whether the button 2240 is pressed. When the button 2240 is pressed, the method proceeds to operation 2920. When the button 2240 is not pressed, the method proceeds to operation 2930.
In operation 2920, the cradle 2 indicates the status of a battery. For example, the control unit 220 may output information regarding the current state of the battery 210 (e.g., remaining power, etc.) on the display 2250.
In operation 2930, the control unit 220 of the cradle 2 determines whether a cable is connected to the cradle 2. For example, the control unit 220 determines whether a cable is connected to an interface (e.g., a USB port, etc.) included in the cradle 2. When a cable is connected to the cradle 2, the method proceeds to operation 2940. Otherwise, the method is terminated.
In operation 2940, the cradle 2 performs a charging operation. For example, the cradle 2 charges the battery 210 by using power supplied through a connected cable.
As described above, a cigarette may be inserted into the holder 1. The cigarette includes an aerosol generating material and aerosol is generated by the heated heater 2130.
Hereinafter, an example of a cigarette that may be inserted into the holder 1 will be described with reference to
Referring to
The cigarette 3 may be similar to a typical burning cigarette. For example, the cigarette 3 may include a first portion 3310 containing an aerosol generating material and a second portion 3320 including a filter and the like. Meanwhile, the cigarette 3 according to one embodiment may also 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 portion of the first portion 3310 may be inserted into the holder 1 or the entire first portion 3310 and a portion the second portion 3320 may be inserted into the holder 1.
A user may inhale the aerosol while holding the second portion 3320 by his/her lips. At this time, the aerosol is mixed with the outside air and is delivered to a user's mouth. As shown in

Comparing
The structures of the cigarette 3 shown in
The tobacco rod 3300 includes an 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. The length of the tobacco rod 3300 may be in the range of about 7 mm to about 15 mm, but, preferably, may be about 12 mm. The diameter of the tobacco rod 3300 may be in the range of about 7 mm to about 9 mm, but, preferably, may be about 7.9 mm. The diameter and length of the tobacco rod 3300 are not limited thereto.
In addition, the tobacco rod 3300 may include other additive materials like a flavoring agent, a wetting agent, and/or an acetate compound. For example, the flavoring agent may include licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascara, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, mint oil, cinnamon, keragene, cognac, jasmine, chamomile, menthol, cinnamon, ylang ylang, salvia, spearmint, ginger, coriander, coffee, etc. In addition, the wetting agent may include glycerin or propylene glycol.
For example, the tobacco rod 3300 may be filled with cut tobacco leaves. Here, cut tobacco leaves may be formed by fine-cutting a tobacco sheet.
For a large wide tobacco sheet to be filled within the tobacco rod 3300 having a narrow space, a special operation for facilitating folding of the tobacco sheet is further needed. Therefore, it is easier to fill the tobacco rod 3300 with cut tobacco leaves than to fill the tobacco rod 3300 with a tobacco sheet, and thus the productivity and the efficiency of the process for producing the tobacco rod 3300 may be improved.
In another example, the tobacco rod 3300 may be filled with a plurality of cigarette strands formed by fine-cutting a tobacco sheet. For example, the tobacco rod 3300 may be formed by combining a plurality of tobacco strands in the same direction (parallel to one another) or randomly. The tobacco strands may be fabricated to each have a cuboidal shape having a horizontal length of 1 mm, a vertical length of 12 mm, and a thickness (height) of 0.1 mm, but the present disclosure is not limited thereto.
When the tobacco rod 3300 is filled with tobacco strands, more aerosol may be generated than when the tobacco rod 3300 is filled with a tobacco sheet. In the case of filling the same space, compared to a tobacco sheet, tobacco strands ensure a greater surface area. A greater surface area indicates that an aerosol generating material has a greater chance of contacting the outside air. Therefore, when the tobacco rod 3300 is filled with tobacco strands, more aerosol may be generated than when the tobacco rod 3300 is filled with a tobacco sheet.
Furthermore, the cigarette 3 may be more easily separated from the holder 1 when the tobacco rod 3300 is filled with tobacco strands than when the tobacco rod 3300 is filled with a tobacco sheet. Compared with a tobacco sheet, tobacco strands generate a small frictional force by contacting the heater 2130. Therefore, when the tobacco rod 3300 is filled with tobacco strands, the cigarette 3 may be more easily separated from the holder 1 than when the tobacco rod 3300 is filled with a tobacco sheet.
A tobacco sheet may be formed by pulverizing a raw tobacco material to form a slurry and then drying the slurry. For example, a 15% to 30% aerosol generating material may be added to the slurry. The raw tobacco material may be tobacco leaf fragments, tobacco stems, fine tobacco powders formed during treatment of tobacco, and/or main lateral strips of tobacco leaves. The tobacco sheet may also include other additives like wood cellulose fibers.
The first filter segment 3321 may be a cellulose acetate filter. For example, the first filter segment 3321 may have a tubular structure including a hollow formed therein. The length of the first filter segment 3321 may be within the range of about 7 mm to about 15 mm, but may be preferably about 7 mm. The length of the first filter segment 3321 may be smaller than about 7 mm, but it is preferable that the first filter segment 3321 has a length such that a function of at least one cigarette element (e.g., a cooling element, a capsule, an acetate filter, etc.) is not damaged. However, the length of the first filter segment 3321 is not limited to the aforementioned numerical ranges. The length of the first filter segment 3321 may be expanded, and the length of the entire cigarette 3 may be adjusted according to the length of the first filter segment 3321.
The second filter segment 3323 may also be a cellulose acetate filter. For example, the second filter segment 3323 may be fabricated as a recess filter with a hollow cavity, but is not limited thereto. The length of the second filter segment 3323 may be within the range of about 5 mm to about 15 mm, but may be preferably about 12 mm. However, the length of the second filter segment 3323 is not limited to the aforementioned numerical ranges.
Also, the second filter segment 3323 may include at least one capsule 3324. Here, the capsule 3324 may have a structure in which a content liquid containing a flavoring material is wrapped with a film. For example, the capsule 3324 may have a spherical or cylindrical shape. The diameter of the capsule 3324 may be no less than 2 mm, but, preferably, may be about 2 to 4 mm.
A material used to form the film of the capsule 3324 may be starch and/or a gelling agent. For example, gellan gum or gelatin may be used as the gelling agent. A gelling agent may be further used as a material for forming the film of the capsule 3324. Here, as the gelling auxiliary agent, for example, a calcium chloride may be used. Furthermore, a plasticizer may be further used as a material for forming the film of the capsule 3324. As the plasticizer, glycerin and/or sorbitol may be used. Furthermore, a coloring agent may be further used as a material for forming the film of the capsule 3324.
For example, as a flavoring material included in the content liquid of the capsule 3324, menthol, plant essential oil, and the like may be used. As a solvent of the flavoring material included in the content liquid, for example, a medium chain fatty acid triglyceride (MCT) may be used. Also, the content liquid may include other additives like a pigment, an emulsifying agent, a thickening agent, etc.
The cooling structure 3322 cools aerosol generated as the heater 2130 heats the tobacco rod 3300. Therefore, a user may inhale aerosol cooled to a suitable temperature. The length of the cooling structure 3322 may be in the range of about 10 mm to about 20 mm, but preferably, may be about 14 mm. However, the length of the cooling structure 3322 is not limited to the aforementioned numerical ranges.
For example, the cooling structure 1322 may be fabricated using polylactic acid. To increase the surface area per unit area (i.e., the surface area contacting aerosol), the cooling structure may be fabricated in various shapes. Various examples of the cooling structure 3322 will be described later with reference to
The tobacco rod 3300 and the first filter segment 3321 are wrapped by a first wrapper 3331. For example, the first wrapper 3331 may be made of an oil-resistant paper packaging material.
The cooling structure 3322 and the second filter segment 3323 are wrapped by a second wrapper 3332. The entire cigarette 3 may be re-wrapped by a third wrapper 3333. For example, the second wrapper 3332 and the third wrapper 3333 may be made of a general paper packaging material. Selectively, the second wrapper 3332 may be made of an oil-resistant hard wrapping paper or a PLA flavored paper. The second wrapper 3332 may wrap the second filter segment 3323 and may further wrap the second filter segment 3323 and the cooling structure 3322.
Referring to
The fourth wrapper 3334 may be produced by applying (or coating) a predetermined material to (or on) one surface or both surfaces of a paper packaging material. Here, an example of the predetermined material may be, but is not limited to, silicon. Silicon exhibits characteristics like heat resistance with little change due to the temperature, oxidation resistance, resistances to various chemicals, water repellency, electrical insulation, or the like. However, any material other than silicon may be applied to (or coated on) the fourth wrapper 3334 without limitation as long as the material exhibits the above-mentioned characteristics.
Although the cigarette 3 includes both the first wrapper 3331 and the fourth wrapper 3334 in
The fourth wrapper 3334 may prevent the cigarette 3 from being burned. For example, when the tobacco rod 3300 is heated by the heater 2130, there is a possibility that the cigarette 3 is burned. In detail, when the temperature is raised to a temperature above the ignition point of any one of the materials included in the tobacco rod 3300, the cigarette 3 may be burned. Even in this case, because the fourth wrapper 3334 includes a non-combustible material, the burning of the cigarette 3 may be prevented.
Furthermore, the fourth wrapper 3334 may prevent the holder 1 from being contaminated by substances formed by the cigarette 3. Through puffs of a user, liquid substances may be formed in the cigarette 3. For example, as the aerosol formed by the cigarette 3 is cooled by the outside air, liquid materials (e.g., moisture, etc.) may be formed. As the fourth wrapper 3334 wraps the tobacco rod 3300 and/or the first filter segment 3321, the liquid materials formed in the cigarette 3 may be prevented from being leaked out of the cigarette 3. Accordingly, the casing 2140 and the like of the holder 1 may be prevented from being contaminated by the liquid materials formed by the cigarette 3.
For example, the cooling structures of
For example, when a film (sheet)-type cooling structure is fabricated by filling a film (sheet), the film (sheet)-type cooling structure may be crushed by an external impact. In this case, the aerosol cooling effect of the cooling structure is deteriorated.
As another example, when a cooling structure is manufactured through extrusion molding or the like, the efficiency of the process is lowered due to addition of operations like cutting of a structure. Also, there are limits in manufacturing a cooling structure in various shapes.
As a cooling structure according to an embodiment is fabricated by using polylactic acid fibers (e.g., weaving), the risk of the cooling structure being deformed or losing its function by an external impact may be reduced. Also, by changing the way of combining the fibers, cooling structures having various shapes may be fabricated.
Furthermore, by fabricating a cooling structure by using fibers, the surface area contacting with aerosol is increased. Therefore, the aerosol cooling effect of the cooling structure may be further improved.

The first cross-section 3551 borders on the first filter segment 3321 and may include a gap into which aerosol is introduced. The second cross-section 3552 borders on the second filter segment 3323 and may include a gap into which aerosol may be released. For example, each of the first cross-section 3551 and the second cross-section 3552 may include a single gap having the same diameter, but the diameters and the numbers of the gaps included in the first cross-section 3551 and the second cross-section 3552 are not limited thereto.
In addition, the cooling structure 3550 may include a third cross-section 3553 including a plurality of gaps between the first cross-section 3551 and the second cross-section 3552. For example, the diameters of the plurality of gaps included in the third cross-section 3553 may be smaller than the diameters of the gaps included in the first cross-section 3551 and the second cross-section 3552. Also, the number of gaps included in the third cross-section 3553 may be greater than the number of gaps included in the first cross-section 3551 and the second cross-section 3552.
