<Aerosol-Generating Device Configured to Process User Input>
FIGS. 1A through 1C are perspective views of an electronic device according to an example embodiment.
Referring to FIGS. 1A and 1B, an electronic device 100 may include a front housing 110 including a display 120, an upper housing 130, a lower housing 140, and a rear housing 150. The respective housings may be connected mechanically or magnetically, and the shape of the electronic device 100 and a method of connecting the housings may be implemented in various ways. The electronic device 100 may include a circuit for performing operations in the housings. For example, the circuit for performing the operations may be implemented on a printed circuit board (PCB) and the PCB may be provided in the housings.
According to an example embodiment, the display 120 included in the front housing 110 may display a screen and receive a user input from a user. The user input may be any one of a button input and a touch input. The display 120 may include at least one of a physical button or a touch panel to receive the user input. Although the display 120 is illustrated as being attached to the outside of the front housing 110 in FIGS. 1A and 1B, examples are not limited to the example embodiment described herein. That is, the display 120 may be attached at any position of each housing.
Referring to FIG. 1B, the upper housing 130 may include a hole to insert a cigarette therein. The structure of the hole may be implemented in various ways depending on the type of cigarette. According to an example embodiment, a sensor for sensing the type of cigarette that is inserted through the hole may be attached to the upper housing 130.
According to an example embodiment, the lower housing 140 may also include a hole for connecting a power terminal to an external power source for supplying power. The electronic device 100 may receive power from an external power source connected to the power terminal. The power terminal may be implemented as a universal serial bus (USB) port (e.g., USB C-type) but is not limited to the example embodiment described herein, and may be implemented in various forms. Such a power terminal hole or power terminal of the lower housing 140 may include a sensor that senses whether a terminal of the external power source is connected thereto.
According to an example embodiment, the electronic device 100 may be an electronic device for generating an aerosol. For example, the electronic device 100 may include a heater that receives power from a power source such as a battery and heats an aerosol-generating substrate of a cigarette inserted in the electronic device 100. The aerosol-generating substrate heated by the heater may generate an aerosol. A detailed configuration of the electronic device 100 will be described hereinafter with reference to FIGS. 2 and 3 .
Referring to FIG. 1C, the electronic device 100 may generate an aerosol by heating an aerosol-generating substrate in a cigarette 2 inserted in the electronic device 100. The user may then be able to inhale the generated aerosol to smoke. The electronic device 100 may heat the aerosol-generating substrate using various methods.
According to an example embodiment, the electronic device 100 may use a heating method by which the heater applies heat directly to the aerosol-generating substrate.
According to another example embodiment, the electronic device 100 may use an inductive heating method that does not directly heat the aerosol-generating substrate. For example, the aerosol-generating substrate may be heated based on an electromagnetic field generated as microwaves resonate, as in a microwave oven.
Referring to FIG. 1C, the cigarette 2 may be divided into a first portion including the aerosol-generating substrate and a second portion including a filter or the like. Alternatively, the second portion of the cigarette 2 may include the aerosol-generating substrate. The first portion may be entirely inserted into the electronic device 100, and the second portion may be exposed outside. Alternatively, the first portion may be only partially inserted into the electronic device 100. In another embodiment, the first portion may be entirely inserted and the second portion may be partially inserted into the electronic device 100. The user may inhale an aerosol through the second portion. In this case, an aerosol may be generated as external air passes through the first portion, and the generated aerosol may be carried into the mouth of the user through the second portion.
FIG. 2 is a diagram illustrating a configuration of an electronic device according to an example embodiment.
According to an example embodiment, the electronic device 100 may include a controller 210 (e.g., a processor), a display unit 220, a battery 230, a heater 240, and an inserter 250 (e.g., a cavity). Although not shown, the electronic device 100 may further include general-purpose components. For example, the electronic device 100 may further include at least one sensor (e.g., a puff sensor, a temperature sensor, a cigarette insertion detection sensor, a power terminal detection sensor, etc.) and a motor for outputting tactile information. As described above with reference to FIGS. 1A through 1C, the electronic device 100 may be manufactured to have a structure in which external air may be introduced or internal gas may be discharged even while the cigarette 2 is inserted.
For example, the external air may be introduced through at least one air path formed in the electronic device 100. In this example, the opening or closing and the size of the air path formed in the electronic device 100 may be adjusted by the user. Accordingly, an amount of atomization, a sense of smoking, or the like may be adjusted by the user. As another example, the external air may be introduced into the inside of the cigarette 2 through at least one hole formed on a surface of the cigarette 2.
According to an example embodiment, although not shown, the electronic device 100 may form a system along with a separate cradle. For example, the cradle may be used to charge the battery 230 of the electronic device 100.
The controller 210 may control operations of the electronic device 100. The controller 210 will be described in detail below with reference to FIG. 3 .
The display unit 220 may output visual information through the display 120 described above with reference to FIGS. 1A through 1C, and receive a user input from the user. The user input may be, for example, a button input or a touch input.
The battery 230 may supply power to the electronic device 100. The battery 230 may receive power from an external power source. For example, as described above with reference to FIGS. 1A through 1C, the lower housing 140 may include a hole for a power terminal, through which power is received from the external power source, and the battery 230 may thereby be charged.
The heater 240 may heat an aerosol-generating substrate of a cigarette provided in the inserter 250. As described above with reference to FIG. 1C, the heater 240 may heat the aerosol-generating substrate in various ways.
According to an example embodiment, the cigarettes 2 of various types may be inserted into the inserter 250. The cigarette 2 may be of a cut tobacco filler type having a shape as a whole tobacco filler that is directly lit to smoke, a granular type including an aerosol-generating material in the form of granules or capsules, or a liquid type including a liquid composition. A cigarette of the liquid type may be manufactured in the form of a stick, and may include a liquid that includes a tobacco-containing material (e.g., a volatile tobacco flavor component) or a liquid that includes a non-tobacco material in the stick.
According to an example embodiment, the cigarette 2 may be inserted such that the inserter 250 surrounds at least a portion (e.g., the aerosol-generating substrate) of the cigarette 2, and the aerosol-generating substrate may be heated by the heater 240. For example, the cigarette 2 may be divided into a first portion including the aerosol-generating substrate and a second portion including a filter or the like. Alternatively, the second portion of the cigarette 2 may also include the aerosol-generating substrate.
According to an example embodiment, the electronic device 100 may further include a communication module including a Bluetooth chip or a Wi-Fi chip, and the controller 210 may use the communication module to communicate with an external device such as a server over a network. When a hub device such as an access point (AP) is present around the electronic device 100, the controller 210 may use the hub device to communicate with the server.
FIG. 3 is a diagram illustrating a configuration of a controller according to an example embodiment.
According to an example embodiment, the controller 210 may include a communication unit 310, a processor 320, and a memory 330.
The communication unit 310 may be connected to the processor 320 and the memory 330 to transmit and receive data thereto and therefrom. The communication unit 310 may be connected to another external device to transmit and receive data thereto and therefrom. Hereinafter, transmitting and receiving “A” may refer to transmitting and receiving “information or data indicating A.”
The communication unit 310 may be implemented as a circuitry in the controller 210. For example, the communication unit 310 may include an internal bus and an external bus. As another example, the communication unit 310 may be an element that connects the controller 210 and an external device. The communication unit 310 may be an interface. The communication unit 310 may receive data from the external device and transmit the data to the processor 320 and the memory 330.
The processor 320 may process the data received by the communication unit 310 and data stored in the memory 330. A processor described herein may be a hardware-implemented processing device having a physically structured circuit to execute desired operations. The desired operations may include, for example, code or instructions included in a program. The hardware-implemented data processing device may include, for example, a microprocessor, a central processing unit (CPU), a processor core, a multi-core processor, a multiprocessor, an application-specific integrated circuit (ASIC), and a field-programmable gate array (FPGA).
The processor 320 may execute computer-readable code (e.g., software) stored in a memory (e.g., the memory 330) and instructions triggered by the processor 320.
The memory 330 may store therein the data received by the communication unit 310 and the data processed by the processor 320. For example, the memory 330 may store therein the program (or an application, or software). The program to be stored may be a set of syntaxes that are coded and executable by the processor 320 to control the electronic device 100.
The memory 330 may include, for example, at least one volatile memory, non-volatile memory, random-access memory (RAM), flash memory, hard disk drive, and optical disc drive.
The memory 330 may store an instruction set (e.g., software) for operating the controller 210. The instruction set for operating the controller 210 may be executed by the processor 320.
The communication unit 310, the processor 320, and the memory 330 will be described in detail below with reference to FIGS. 4A through 6 .
FIGS. 4A and 4B are diagrams illustrating examples of a screen displayed on an electronic device according to an example embodiment.
FIG. 4A illustrates a main screen displayed on the display 120 of the electronic device 100. On the main screen, an icon 410 for initiating smoking, an icon 420 for setting a communication state, and an icon 430 for checking battery information may be displayed. On the main screen, time information 440 and weather information 460 may also be displayed.
According to an example embodiment, the processor 320 described above with reference to FIG. 3 may receive a user input by touching, tapping, dragging, and the like performed on the display 120. When the user taps (or touches) the icon 430 for checking the battery information, a screen as shown in FIG. 4B may be displayed.
According to an example embodiment, FIG. 4A may be a diagram illustrating a screen displayed on the display 120 of the electronic device 100 when the electronic device 100 is being charged.
According to an example embodiment, the electronic device 100 may generate an aerosol for a user to smoke by heating the aerosol-generating substrate of the cigarette 2 as described above with reference to FIGS. 1A through 3 , but may also provide other functions to the user. For example, the electronic device 100 may provide the time information 440 and the weather information 460, and may perform an operation through an application installed in the electronic device 100.
According to an example embodiment, the processor 320 may determine whether the user input, which is input to the electronic device 100, is a heating command to heat the aerosol-generating substrate. For example, when the user input is received through the icon 410 for initiating smoking, the processor 320 may determine that the user input is the heating command to heat the aerosol-generating substrate of the cigarette 2 in the inserter 250 by the heater 240. However, this configuration is not limited to the example embodiment described herein, and the processor 320 may determine whether the user input is the heating command according to user inputs input to various user interfaces.
According to an example embodiment, when the user input is the heating command, the processor 320 may determine whether the electronic device 100 is being charged. When power is being supplied to the battery 230 from an external source, the processor 320 may determine that the electronic device 100 is being charged. According to another example embodiment, a power terminal hole or power terminal of the lower housing 140 of the electronic device 100 may include a sensor that senses whether a terminal of the external power source is connected thereto, and the processor 320 may determine whether the electronic device 100 is being charged based on the sensor.
If the electronic device 100 heats the aerosol-generating substrate of the cigarette 2 placed in the inserter 250 by the heater 240 while being charged, this may cause a malfunction of the electronic device 100. Accordingly, in a case where the user input is the heating command when the electronic device 100 is being charged, the processor 320 may invalidate the user command. For example, the processor 320 may not perform the heating command received by the electronic device 100. According to an example embodiment, the processor 320 may display a guide message 450 indicating that the heating command is unable to be executed while being charged. According to another example embodiment, the processor 320 may provide tactile (e.g., haptic) feedback through a motor for outputting tactile information included in the electronic device 100. According to still another example embodiment, the processor 320 may provide visual feedback of a blinking red light using an indicator. However, the configuration is not limited to the example embodiments described herein, and the processor 320 may notify the user in various ways that the heating command cannot be executed while being charged.
According to an example embodiment, when the user input is not the heating command, the processor 320 may perform an operation corresponding to the user input. For example, when a user input 435 is received through the icon 430 for checking the battery information during the battery charging, the processor 320 may perform a corresponding operation without invalidating the user input. An example embodiment of performing an operation corresponding to a user input other than a heating command while being charged will be described in detail with reference to FIG. 4B.
FIG. 4B illustrates a screen of the display 120 of the electronic device 100 that displays battery information. According to an example embodiment, the screen of FIG. 4B may be displayed when the user input 435 is received through the icon 430 for checking the battery information while the electronic device 100 is being charged.
Even if the user input is received when the electronic device 100 is being charged, the processor 320 may perform an operation corresponding to the user input as long as the user input is not the heating command. For example, when a user input for checking the battery status is received during charging, battery information 480 may be displayed as shown in FIG. 4B. According to an example embodiment, information 490 about the remaining number of times of use according to a current battery state may be further displayed. In addition to battery-related information, time information 470 or the like may be displayed on the screen.
Although FIG. 4B illustrates an example embodiment of checking the battery information, it is not limited to the example embodiment described herein. As long as the user input is not the heating command, the processor 320 may perform various operations corresponding to the user inputs. For example, various applications may be installed in the electronic device 100, and when a user input for an application is received while being charged, the processor 320 may perform an operation through the corresponding application. With this configuration, the user may use functions other than the heating of the aerosol-generating substrate, even when the electronic device 100 is being charged.
According to an example embodiment, even when the user input, which is the heating command, is received while being charged, if remaining power of the battery 230 is greater than or equal to a threshold value, the processor 320 may stop the charging and perform the heating command corresponding to the user input. For example, when the remaining power of the battery 230 is 50% or more and the heating command is received, the processor 320 may cut off the power supply from an external power source and perform the heating command. For example, the electronic device 100 may further include a circuit capable of cutting off the power supply, and the processor 320 may control the circuit to cut off the power supply even when an external source is connected thereto.
According to an example embodiment, the processor 320 may provide a guide message such as “Do you want to stop charging and proceed with heating?” on the display 120, and may stop the charging and perform the heating command according to a user input such as a touch of a confirmation button. As described above with reference to FIGS. 1A through 3 , the processor 320 may heat the aerosol-generating substrate of the cigarette 2 in the inserter 250 by the heater 240, and the user may inhale an aerosol generated by heating the aerosol-generating substrate through the cigarette 2.
<User Input Processing Method>
FIG. 5 is a flowchart illustrating a user input processing method according to an example embodiment.
Operations 510 through 540 described below may be performed by the processor 320 of the electronic device 100 described above with reference to FIGS. 1 through 4B, and a repeated description may be omitted.
In operation 510, the processor 320 may receive a user input from a user. For example, the processor 320 may receive a user input through a touch panel or the like included in the display 120.
In operation 520, the processor 320 may determine whether the user input is a heating command to heat an aerosol-generating substrate of the cigarette 2. When the user input is not the heating command, the processor 320 may perform an operation corresponding to the user input in operation 550 described below.
In operation 530, when the user input is the heating command to heat the aerosol-generating substrate of the cigarette 2, the processor 320 may determine whether the electronic device 100 is being charged. When the electronic device 100 is not being charged, the processor 320 may perform an operation corresponding to the user input in operation 550. For example, when the user input is the heating command, the processor 320 may heat the aerosol-generating substrate of the cigarette 2 in the inserter 250 by the heater 240. As another example, when the user input is a messenger application execution command, the processor 320 may execute the corresponding application.
In operation 540, in a case where the user input is the heating command when the electronic device 100 is being charged, the processor 320 may invalidate the user input. For example, the processor 320 may not execute the heating command received by the electronic device 100. As described above with reference to FIG. 4A, the processor 320 may notify the user in various ways that the heating command is unable to be executed while being charged.
According to an example embodiment, after the processor 320 invalidates the user input in operation 540, when a user input received again from the user (operation 510) is not a heating command (operation 520), the processor 320 may perform an operation corresponding to the user input in operation 550. With this configuration, the electronic device 100 may perform an operation corresponding to a user input other than a heating command, even when the electronic device 100 is being charged.
FIG. 6 is a flowchart illustrating a user input processing method performed when a heating command is input while being charged according to an example embodiment.
Operations 610 and 620 described below may be performed by the processor 320 of the electronic device 100 described above with reference to FIGS. 1 through 5 , and a repeated description may be omitted. Operations 610 and 620 may be performed after operation 530 described above with reference to FIG. 5 is performed.
According to an example embodiment, in a case where the user input is the heating command when the electronic device 100 is being charged, in operation 610, the processor 320 may check the remaining power of the battery 230. When the remaining power of the battery 230 is greater than or equal to a threshold value, in operation 620, the processor 320 may stop the charging and perform the heating command. For example, when the remaining power of the battery 230 is 50% or more, the processor 320 may cut off the power supply from an external power source and perform the heating command. As described above with reference to FIG. 4B, the processor 320 may further display a message for user confirmation and perform the heating command based on an input of the user confirmation.
According to an example embodiment described with reference to FIG. 6 , even when the heating command is input while being charged, if the remaining power of the battery is greater than or equal to the threshold value, the processor 320 may stop the charging and heat the aerosol-generating substrate of the cigarette 2 in the inserter 250 by the heater 240, such that the user may smoke even when a charging terminal is connected to the electronic device 100.

The controller 12 may control the overall operation of the aerosol-generating device 1. For example, the controller 12 may control respective operations of other components included in the aerosol-generating device 1 in addition to the battery 11, the heater 13, and the vaporizer 14. In addition, the controller 12 may verify a state of each of the components of the aerosol-generating device 1 to determine whether the aerosol-generating device 1 is in an operable state.
The controller 12 may include at least one processor. The processor may be implemented as an array of a plurality of logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory in which a program executable in the microprocessor is stored. In addition, it is to be understood by those having ordinary skill in the art to which the present disclosure pertains that the processor may be implemented in other types of hardware.
The heater 13 may be heated by the power supplied by the battery 11. For example, when the cigarette 2 is inserted into the aerosol-generating device 1, the heater 13 may be disposed outside the cigarette 2 such that the heated heater 13 raises the temperature of an aerosol-generating material in the cigarette 2.
For example, the heater 13 may be an electrically resistive heater. In this example, the heater 13 may include an electrically conductive track, and the heater 13 may be heated as a current flows through the electrically conductive track. However, the heater 13 is not limited to the above-described example, and other types of heating the heater 13 may be heated to a desired temperature without limitation. The desired temperature may be preset in the aerosol-generating device 1 or may be set by the user.
As another example, the heater 13 may be an inductive heating-type heater. In this example, the heater 13 may include an electrically conductive coil for heating the cigarette 2 by inductive heating, and the cigarette 2 may include a susceptor to be heated by the inductive heating-type heater.
For example, the heater 13 may include a tubular heating element, a plate-shaped heating element, a needle-shaped heating element, or a rod-shaped heating element, and may heat the inside or outside of the cigarette 2 according to the shape of a heating element.
In addition, the heater 13 may be provided as a plurality of heaters in the aerosol-generating device 1. In this case, the heaters may be disposed to be inserted into the cigarette 2, or may be disposed outside the cigarette 2. In addition, when the cigarette 2 is inserted in the aerosol-generating device 1, some of the heaters 13 may be inserted into the cigarette 2, and the rest may be disposed outside the cigarette 2. However, the shape of the heater 13 is not limited to what is shown in FIGS. 7 through 9 but may be provided in various shapes.
The vaporizer 14 may heat a liquid composition to generate an aerosol, and the generated aerosol may pass through the cigarette 2 to the user. That is, the aerosol generated by the vaporizer 14 may travel along an airflow path of the aerosol-generating device 1, and the airflow path may be configured such that the aerosol generated by the vaporizer 14 passes through the cigarette 2 to be provided to the user.
For example, the vaporizer 14 may include a liquid storage, a liquid transfer means, and a heating element, but is not limited thereto. For example, the liquid storage, the liquid transfer means, and the heating element may be included as independent modules in the aerosol-generating device 1.
The liquid storage may store the liquid composition. The liquid composition may be, for example, a liquid including a tobacco-containing material that includes a volatile tobacco flavor component, or may be a liquid including a non-tobacco material. The liquid storage may be detachable from the vaporizer 14, or may be manufactured integrally with the vaporizer 14.
The liquid composition may include, for example, water, a solvent, ethanol, a plant extract, a fragrance, a flavoring agent, or a vitamin mixture. The fragrance may include, for example, menthol, peppermint, spearmint oil, various fruit flavoring ingredients, and the like, but is not limited thereto. The flavoring agent may include ingredients that provide the user with a variety of flavors or scents. The vitamin mixture may be a mixture of at least one of vitamin A, vitamin B, vitamin C, or vitamin E, but is not limited thereto. The liquid composition may also include an aerosol former such as glycerin and propylene glycol.
The liquid transfer means may transfer the liquid composition in the liquid storage to the heating element. The liquid transfer means may be, for example, a wick such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic, but is not limited thereto.
The heating element may be an element for heating the liquid composition transferred by the liquid transfer means. The heating element may be, for example, a metal heating wire, a metal heating plate, a ceramic heater, or the like, but is not limited thereto. Further, the heating element may include a conductive filament such as a nichrome wire, and may be wound around the liquid transfer means. The heating element may be heated as a current is applied and may transfer heat to the liquid composition in contact with the heating element, and may thereby heat the liquid composition. As a result, an aerosol may be generated.
For example, the vaporizer 14 may also be referred to as a cartomizer or an atomizer, but is not limited thereto.
The aerosol-generating device 1 may further include general-purpose components in addition to the battery 11, the controller 12, the heater 13, and the vaporizer 14. For example, the aerosol-generating device 1 may include a display that outputs visual information and/or a motor that outputs tactile information. In addition, the aerosol-generating device 1 may include at least one sensor (e.g., a puff sensor, a temperature sensor, a cigarette insertion detection sensor, etc.). In addition, the aerosol-generating device 1 may be manufactured to have a structure in which external air may be introduced or internal gas may flow out even with the cigarette 2 being inserted.
Although not shown in FIGS. 7 through 9 , the aerosol-generating device 1 may form a system along with a separate cradle. For example, the cradle may be used for charging the battery 11 of the aerosol-generating device 1. Alternatively, the cradle may be used to heat the heater 13 while the aerosol-generating device 1 is coupled to the cradle.
The cigarette 2 may be similar to one of a general burning type cigarette. For example, the cigarette 2 may include a first portion including an aerosol-generating material and a second portion including a filter or the like. Alternatively, the second portion of the cigarette 2 may also include the aerosol-generating material. For example, the aerosol-generating material provided in the form of granules or capsules may be inserted into the second portion.
The first portion may be entirely inserted into the aerosol-generating device 1, and the second portion may be exposed outside. Alternatively, the first portion may be partially inserted into the aerosol-generating device 1, and the first portion may be entirely inserted and the second portion may be partially inserted into the aerosol-generating device 1. The user may then inhale an aerosol with the second portion in their mouth. In this case, an aerosol may be generated as external air passes through the first portion, and the generated aerosol may pass through the second portion to be into the mouth of the user.
For example, the external air may be introduced through at least one air path formed in the aerosol-generating device 1. In this example, the opening or closing and/or the size of the air path formed in the aerosol-generating device 1 may be adjusted by the user. Accordingly, an amount of atomization, a sense of smoking, or the like may be adjusted by the user. As another example, the external air may be introduced into the inside of the cigarette 2 through at least one hole formed on a surface of the cigarette 2.
Hereinafter, examples of the cigarette 2 will be described with reference to FIGS. 10 and 11 .
FIGS. 10 and 11 are perspective views of examples of a cigarette according to an example embodiment.
A cigarette 2 shown in FIGS. 10 and 11 may correspond to the cigarette 2 described above with reference to FIG. 1C.
Referring to FIG. 10 , the cigarette 2 may include a tobacco rod 21 and a filter rod 22. The first portion and the second portion described above with reference to FIGS. 7 through 9 may include the tobacco rod 21 and the filter rod 22, respectively.
Although the filter rod 22 is illustrated as having a single segment in FIG. 10 , embodiments are not limited thereto. That is, the filter rod 22 may include a plurality of segments. For example, the filter rod 22 may include a segment that cools an aerosol and a segment that filters out certain components contained in the aerosol. In addition, the filter rod 22 may further include at least one segment that performs another function, as needed.
A diameter of the cigarette 2 may be in a range of 5 millimeters (mm) to 9 mm, and a length thereof may be approximately 48 mm. However, the cigarette 2 is not limited thereto. For example, a length of the tobacco rod 21 may be approximately 12 mm, a length of a first segment of the filter rod 22 may be approximately 10 mm, a length of a second segment of the filter rod 22 may be approximately 14 mm, and a length of a third segment of the filter rod 22 may be approximately 12 mm. However, examples are not limited thereto.
The cigarette 2 may be wrapped with at least one wrapper 24. The wrapper 24 may have at least one hole through which external air is introduced or internal gas is discharged outside. For example, the cigarette 2 may be wrapped with one wrapper 24. As another example, the cigarette 2 may be wrapped with two or more wrappers 24 in an overlapping manner. For example, the tobacco rod 21 may be wrapped with a first wrapper 24 a, and the filter rod 22 may be wrapped with wrappers 24 b, 24 c, and 24 d. In addition, the cigarette 2 may be entirely wrapped again with a single wrapper 24 e. For example, when the filter rod 22 includes a plurality of segments, the segments may be wrapped with the wrappers 24 b, 24 c, and 24 d, respectively.
The first wrapper 24 a and the second wrapper 24 b may be formed of general filter wrapping paper. For example, the first wrapper 24 a and the second wrapper 24 b may be porous wrapping paper or non-porous wrapping paper. In addition, the first wrapper 24 a and the second wrapper 24 b may be formed of oilproof paper and/or an aluminum laminated wrapping material.
The third wrapper 24 c may be formed of hard wrapping paper. For example, a basis weight of the third wrapper 24 c may be in a range of 88 grams per square meter (g/m²) to 96 g/m², and may be desirably in a range of 90 g/m²to 94 g/m². In addition, a thickness of the third wrapper 24 c may be in a range of 120 micrometers (μm) to 130 μm, and may be desirably 125 μm.
The fourth wrapper 24 d may be formed of oil-proof hard wrapping paper. For example, a basis weight of the fourth wrapper 24 d may be in a range of 88 g/m²to 96 g/m², and may be desirably in a range of 90 g/m²to 94 g/m². In addition, a thickness of the fourth wrapper 24 d may be in a range of 120 μm to 130 μm, and may be desirably 125 μm.
The fifth wrapper 24 e may be formed of sterile paper (e.g., MFW). The sterilized paper (MFW) refers to paper specially prepared to enhance tensile strength, water resistance, smoothness, or the like, compared to general paper. For example, a basis weight of the fifth wrapper 24 e may be in a range of 57 g/m²to 63 g/m², and may be desirably 60 g/m². In addition, a thickness of the fifth wrapper 24 e may be in a range of 64 μm to 70 μm, and may be desirably 67 μm.
The fifth wrapper 24 e may have a predetermined material internally added thereto. The material may be, for example, silicon, but is not limited thereto. Silicon may have properties, such as, for example, heat resistance with less change by temperature, oxidation resistance, resistance to various chemicals, water repellency against water, or electrical insulation. However, silicon may not be necessarily used, but any material having such properties described above may be applied (or coated) on the fifth wrapper 24 e without limitation.
The fifth wrapper 24 e may prevent the cigarette 2 from burning. For example, when the tobacco rod 21 is heated by the heater 13, the cigarette 2 may be likely to burn. For example, when the temperature rises above an ignition point of any one of materials included in the tobacco rod 21, the cigarette 2 may burn. Even in this case, it may still be possible to prevent the cigarette 2 from burning because the fifth wrapper 24 e includes a non-combustible material.
In addition, the fifth wrapper 24 e may prevent a holder from being contaminated by substances produced in the cigarette 2. For example, liquid substances may be produced in the cigarette 2 by puffs from the user. For example, as an aerosol generated in the cigarette 2 is cooled by external air, such liquid substances (e.g., water, etc.) may be produced. Thus, wrapping the cigarette 2 with the fifth wrapper 24 e may prevent the liquid substances produced in the cigarette 2 from leaking out of the cigarette 2.
The tobacco rod 21 may include an aerosol-generating material. The aerosol-generating material may include, for example, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, or oleyl alcohol, but is not limited thereto. The tobacco rod 21 may also include other additives, such as, for example, a flavoring agent, a wetting agent, and/or an organic acid. In addition, the tobacco rod 21 may include a flavoring liquid such as menthol or a moisturizing agent that is added as being sprayed onto the tobacco rod 21.
The tobacco rod 21 may be manufactured in various forms. For example, the tobacco rod 21 may be manufactured as a sheet or as a strand. The tobacco rod 21 may also be formed with a cut tobacco filler from finely cut tobacco sheets. In addition, the tobacco rod 21 may be enveloped by a heat-conductive material. The heat-conductive material may be, for example, a metal foil such as an aluminum foil, but is not limited thereto. For example, the heat-conductive material enveloping the tobacco rod 21 may evenly distribute the heat transferred to the tobacco rod 21 to improve the thermal conductivity to be applied to the tobacco rod 21, thereby improving the taste of tobacco. In addition, the heat-conductive material enveloping the tobacco rod 21 may function as a susceptor heated by an inductive heater. In this case, although not shown, the tobacco rod 21 may further include an additional susceptor in addition to the heat-conductive material enveloping the outside.
The filter rod 22 may be a cellulose acetate filter. However, there is no limit to the shape of the filter rod 22. For example, the filter rod 22 may be a cylindrical rod, or a tubular rod including a hollow therein. The filter rod 22 may also be a recess-type rod. For example, when the filter rod 22 includes a plurality of segments, at least one of the segments may be manufactured in a different shape.
In this example, a first segment of the filter rod 22 may be a cellulose acetate filter. For example, the first segment may be a tubular structure including a hollow therein. In this example, the first segment may prevent internal materials of the tobacco rod 21 from being pushed back when the heater 13 is inserted and generate an aerosol cooling effect. A desirable diameter of the hollow included in the first segment may be adopted from a range of 2 mm to 4.5 mm, but is not limited thereto.
A desirable length of the first segment may be adopted from a range of 4 mm to 30 mm, but is not limited thereto. The length of the first segment may be desirably 10 mm, but is not limited thereto.
The first segment may have a certain hardness that is adjusted by adjusting the plasticizer content in a process of manufacturing the first segment. In addition, a structure such as a film or a tube of the same or different material may be included in the first segment.
A second segment of the filter rod 22 may cool an aerosol generated as the heater 13 heats the tobacco rod 21. The user may thus inhale the aerosol cooled down to a suitable temperature.
A length or diameter of the second segment may be determined in various ways according to the shape of the cigarette 2. For example, a desirable length of the second segment may be adopted from a range of 7 mm to 20 mm. The length of the second segment may be desirably approximately 14 mm, but is not limited thereto.
The second segment may be manufactured by weaving polymer fiber. In this case, a flavoring liquid may be applied to the fiber formed of a polymer. Alternatively, the second segment may be manufactured by weaving a separate fiber to which a flavoring liquid is applied and the fiber formed of the polymer together. Alternatively, the second segment may be formed with a crimped polymer sheet.
For example, the polymer may be prepared with a material selected from the group consisting of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polylactic acid (PLA), cellulose acetate (CA) and aluminum foil.
As the second segment is formed with the woven polymer fiber or the crimped polymer sheet, the second segment may include a single channel or a plurality of channels extending in a longitudinal direction. A channel used herein may refer to a path through which a gas (e.g., air or aerosol) passes.
For example, the second segment formed with the crimped polymer sheet may be formed from a material having a thickness between approximately Slim and approximately 300 μm, for example, between approximately 10 μm and approximately 250 μm. In addition, a total surface area of the second segment may be between approximately 300 mm²/mm and approximately 1000 mm²/mm. Further, an aerosol cooling element may be formed from a material having a specific surface area between approximately 10 mm²/mg and approximately 100 mm²/mg.
The second segment may include a thread containing a volatile flavor ingredient. The volatile flavor ingredient may be menthol, but is not limited thereto. For example, the thread may be filled with a sufficient amount of menthol to provide at least 1.5 milligrams (mg) of menthol to the second segment.
A third segment of the filter rod 22 may be a cellulose acetate filter. A desirable length of the third segment may be adopted from a range of 4 mm to 20 mm. For example, the length of the third segment may be approximately 12 mm, but is not limited thereto.
The third segment may be manufactured such that a flavor is generated by spraying a flavoring liquid onto the third segment in a process of manufacturing the third segment. Alternatively, a separate fiber to which the flavoring liquid is applied may be inserted into the third segment. An aerosol generated by the tobacco rod 21 may be cooled as it passes through the second segment of the filter rod 22, and the cooled aerosol may pass through the third segment into the user. Accordingly, when a flavoring element is added to the third segment, the durability of the flavor to be delivered to the user may be enhanced.
In addition, the filter rod 22 may include at least one capsule 23. The capsule 23 may perform a function of generating a flavor, or a function of generating an aerosol. For example, the capsule 23 may be of a structure in which a liquid containing a fragrance is wrapped with a film. The capsule 23 may have a spherical or cylindrical shape, but is not limited thereto.
Referring to FIG. 11 , a cigarette 3 may further include a front end plug 33. The front end plug 33 may be disposed on one side of a tobacco rod 31 opposite to a filter rod 32. The front end plug 33 may prevent the tobacco rod 31 from escaping to the outside, and may also prevent an aerosol liquefied from the tobacco rod 31 during smoking from flowing into an aerosol-generating device (e.g., the aerosol-generating device 1 of FIGS. 7 through 9 ).
The filter rod 32 may include a first segment 32 a and a second segment 32 b. The first segment 32 a may correspond to the first segment of the filter rod 22 of FIG. 10 , and the second segment 32 b may correspond to the third segment of the filter rod 22 of FIG. 10 .
A diameter and a total length of the cigarette 3 may correspond to the diameter and the total length of the cigarette 2 of FIG. 10 . For example, a length of the front end plug 33 may be approximately 7 mm, a length of the tobacco rod 31 may be approximately 15 mm, a length of the first segment 32 a may be approximately 12 mm, and a length of the second segment 32 b may be approximately 14 mm. However, the examples are not limited thereto.
The cigarette 3 may be wrapped with at least one wrapper 35. The wrapper 35 may have at least one hole through which external air flows inside or internal gas flows outside. For example, the front end plug 33 may be wrapped with a first wrapper 35 a, the tobacco rod 31 may be wrapped with a second wrapper 35 b, the first segment 32 a may be wrapped with a third wrapper 35 c, and the second segment 32 b may be wrapped with a fourth wrapper 35 d. In addition, the cigarette 3 may be entirely wrapped again with a fifth wrapper 35 e.
In addition, at least one perforation 36 may be formed on the fifth wrapper 35 e. For example, the perforation 36 may be formed in an area surrounding the tobacco rod 31, but is not limited thereto. The perforation 36 may perform a function of transferring heat generated by the heater 13 shown in FIGS. 8 and 9 to the inside of the tobacco rod 31.
In addition, the second segment 32 b may include at least one capsule 34. The capsule 34 may perform a function of generating a flavor or a function of generating an aerosol. For example, the capsule 34 may have a structure in which a liquid containing a fragrance is wrapped with a film. The capsule 34 may have a spherical or cylindrical shape, but is not limited thereto.
The first wrapper 35 a may be a combination of general filter wrapping paper and a metal foil such as an aluminum foil. For example, a total thickness of the first wrapper 35 a may be in a range of 45 μm to 55 μm, and may be desirably 50.3 μm. In addition, a thickness of the metal foil of the first wrapper 35 a may be in a range of 6 μm to 7 μm, and may be desirably 6.3 lim. In addition, a basis weight of the first wrapper 35 a may be in a range of 50 g/m²to 55 g/m², and may be desirably 53 g/m².
The second wrapper 35 b and the third wrapper 35 c may be formed with general filter wrapping paper. The second wrapper 35 b and the third wrapper 35 c may each be, for example, porous wrapping paper or non-porous wrapping paper.
For example, the porosity of the second wrapper 35 b may be 35000 CU, but is not limited thereto. In addition, a thickness of the second wrapper 35 b may be in a range of 70 μm to 80 μm, and may be desirably 78 μm. In addition, a basis weight of the second wrapper 35 b may be in a range of 20 g/m²to 25 g/m², and may be desirably 23.5 g/m².
For example, the porosity of the third wrapper 35 c may be 24000CU, but is not limited thereto. In addition, a thickness of the third wrapper 35 c may be in a range of 60 μm to 70 μm, and may be desirably 68 μm. In addition, a basis weight of the third wrapper 35 c may be in a range of 20 g/m²to 25 g/m², and may be desirably 21 g/m².
The fourth wrapper 35 d may be formed with polylactic acid (PLA) laminated paper. The PLA laminated paper may refer to three-ply paper including a paper layer, a PLA layer, and a paper layer. For example, a thickness of the fourth wrapper 35 d may be in a range of 100 μm to 120 μm, and may be desirably 110 μm. In addition, a basis weight of the fourth wrapper 35 d may be in a range of 80 g/m²to 100 g/m², and may be desirably 88 g/m².
The fifth wrapper 35 e may be formed of sterile paper (e.g., MFW). The sterile paper (MFW) may refer to paper specially prepared such that it has enhanced tensile strength, water resistance, smoothness, or the like, compared to those of general paper. For example, a basis weight of the fifth wrapper 35 e may be in a range of 57 g/m²to 63 g/m², and may be desirably 60 g/m². In addition, a thickness of the fifth wrapper 35 e may be in a range of 64 μm to 70 μm, and may be desirably 67 μm.
The fifth wrapper 35 e may have a predetermined material internally added thereto. The material may be, for example, silicon, but is not limited thereto. Silicon may have properties, such as, for example, heat resistance with less change by temperature, oxidation resistance, resistance to various chemicals, water repellency against water, or electrical insulation. However, silicon may not be necessarily used, but any material having such properties described above may be applied (or coated) to the fifth wrapper 35 e without limitation.
The front end plug 33 may be formed of cellulose acetate. For example, the front end plug 33 may be manufactured by adding a plasticizer (e.g., triacetin) to cellulose acetate tow. A mono denier of a filament constituting the cellulose acetate tow may be in a range of 1.0 to 10.0, and may be desirably in a range of 4.0 to 6.0. The mono denier of the filament of the front end plug 33 may be more desirably 5.0. In addition, a cross section of the filament constituting the front end plug 33 may be Y-shaped. A total denier of the front end plug 33 may be in a range of 20000 to 30000, and may be desirably in a range of 25000 to 30000. The total denier of the front end plug 33 may be more desirably 28000.
In addition, as needed, the front end plug 33 may include at least one channel, and a cross-sectional shape of the channel may be provided in various ways.
The tobacco rod 31 may correspond to the tobacco rod 21 described above with reference to FIG. 10 . Thus, a detailed description of the tobacco rod 31 will be omitted here.
The first segment 32 a may be formed of cellulose acetate. For example, the first segment 32 a may be a tubular structure including a hollow therein. The first segment 32 a may be manufactured by adding a plasticizer (e.g., triacetin) to cellulose acetate tow. For example, a mono denier and a total denier of the first segment 32 a may be the same as the mono denier and the total denier of the front end plug 33.
The second segment 32 b may be formed of cellulose acetate. A mono denier of a filament constituting the second segment 32 b may be in a range of 1.0 to 10.0, and may be desirably in a range of 8.0 to 10.0.

FIG. 12 is a block diagram illustrating an aerosol-generating device 9 according to another example embodiment.
In FIG. 12 described below, the aerosol-generating device 9 may correspond to the electronic device 100 described above with reference to FIGS. 1A through 2 . A display 93 a or user input unit 96 may correspond to the display unit 220 described above with reference to FIG. 2 or the display 120 described above with reference to FIGS. 1A through 1C. A battery 94 may correspond to the battery 230 described above with reference to FIG. 2 . A heater 95 may correspond to the heater 240 described above with reference to FIG. 2 .
According to an example embodiment, the aerosol-generating device 9 may include a controller 91, a sensing unit 92, an output unit 93, a battery 94, a heater 95, a user input unit 96, a memory 97, and a communication unit 98. However, an internal structure of the aerosol-generating device 9 is not limited to what is shown in FIG. 12 . It is to be understood by those having ordinary skill in the art to which the present disclosure pertains that some of the components shown in FIG. 12 may be omitted or new components may be added according to the design of the aerosol-generating device 9.
The sensing unit 92 may sense a state of the aerosol-generating device 9 or a state of an environment around the aerosol-generating device 9, and transmit sensing information obtained through the sensing to the controller 91. Based on the sensing information, the controller 91 may control the aerosol-generating device 9 to control operations of the heater 95, restrict smoking, determine whether an aerosol-generating item (e.g., a cigarette, a cartridge, etc.) is inserted, display a notification, and perform other functions.
The sensing unit 92 may include at least one of a temperature sensor 92 a, an insertion detection sensor 92 b, or a puff sensor 92 c, but is not limited thereto.
The temperature sensor 92 a may sense a temperature at which the heater 95 (or an aerosol-generating material) is heated. The aerosol-generating device 9 may include a separate temperature sensor for sensing a temperature of the heater 95, or the heater 95 itself may perform a function as a temperature sensor. Alternatively, the temperature sensor 92 a may be arranged around the battery 94 to monitor a temperature of the battery 94.
The insertion detection sensor 92 b may sense whether the aerosol-generating item is inserted or removed. The insertion detection sensor 92 b may include, for example, at least one of a film sensor, a pressure sensor, a light sensor, a resistive sensor, a capacitive sensor, an inductive sensor, or an infrared sensor, which may sense a signal change by the insertion or removal of the aerosol-generating item.
The puff sensor 92 c may sense a puff from a user based on various physical changes in an airflow path or airflow channel. For example, the puff sensor 92 c may sense the puff based on any one of a temperature change, a flow change, a voltage change, and a pressure change.
The sensing unit 92 may further include at least one of a temperature/humidity sensor, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a gyroscope sensor, a position sensor (e.g., a global positioning system (GPS)), a proximity sensor, and a red, green, blue (RGB) sensor (e.g., an illuminance sensor), in addition to the sensors 92 a through 92 c described above. A function of each sensor may be intuitively inferable from its name by those having ordinary skill in the art, and thus a more detailed description thereof will be omitted here.
The output unit 93 may output information about the state of the aerosol-generating device 9 and provide the information to the user. The output unit 93 may include at least one of a display 93 a, a haptic portion 93 b, or a sound outputter 93 c, but is not limited thereto.
