Description

Technical Field

[0001] The present invention relates to an aerosol generation device, and particularly to recognizing a puff of a user and providing various feedbacks.

Background Art

[0002] Existing smoking articles have used a method of generating an aerosol by directly burning an aerosol generating substance during use. However, when the aerosol generating substance is directly burned, undesired volatile compounds are generated, causing health problems. Therefore, recently, various aerosol generation devices have been developed that heat the aerosol generating substance without burning it, so that no undesired volatile compounds are generated and the flavor of cigarettes is provided.

[0003] However, compared with existing combustion-type cigarettes, the aerosol generation device cannot provide sufficient satisfaction to users. For example, the aerosol generation device feels slightly different from that provided by existing combustion-type cigarettes, and there is also a difference from existing combustion-type cigarettes in the number of puffs and the amount of aerosol substance generated.

[0004] Therefore, there is a need for a method that allows users to use an aerosol generation device and obtain a feeling similar to the smoking feeling to the maximum extent.

[Modes for carrying out the invention]

[0026] To solve the problems of the prior art described above, some embodiments of the holder include a battery for supplying power, a heater for heating an aerosol generating substance, a sensor, at least one output unit, and a control unit, wherein the control unit can use the sensor to sense the user's puff and control the at least one output unit based on puff characteristic data corresponding to the sensing result.

[0027] The terminology used in this invention has been selected as widely used and common terms as possible, taking into account the function of the invention, although this may vary depending on the intentions of those skilled in the art, precedents, or the emergence of new technologies. In certain cases, the applicant may have arbitrarily selected some terms, in which case their meaning will be described in detail in the description of the invention. Therefore, the terminology used in this invention must not be merely a set of names, but must be defined based on the meaning of the term and the overall content of the invention.

[0028] Throughout the specification, when a part is described as being connected to another part, this includes not only direct connection but also electrical connection with other elements in between. Furthermore, when a part is described as containing a component, this does not exclude other components, unless otherwise specified, but rather means that it may contain other components. Also, terms such as "...part" and "module" used in the specification mean a unit that processes at least one function or operation, which may be embodied by hardware or software, or by a combination of hardware and software.

[0029] Throughout this specification, the term "aerosol-generating substance" means a substance capable of generating an aerosol, and also means an aerosol-forming substrate. The aerosol may contain volatile compounds. The aerosol-generating substance may be a solid or a liquid.

[0030] For example, a solid aerosol-producing substance may include solid materials based on tobacco raw materials such as flat tobacco leaves, shredded tobacco, and reconstituted tobacco, and a liquid aerosol-producing substance may include liquid materials based on nicotine, tobacco extracts, and various flavoring agents. It goes without saying that the examples above are not exhaustive.

[0031] Throughout this specification, the aerosol generating device (hereinafter referred to as the "holder") is also a device that uses an aerosol generating substance to generate an aerosol that can be directly inhaled into the user's lungs through the user's mouth. The terms "aerosol generating device" and "holder" can be used interchangeably.

[0032] Throughout this specification, "puff" means inhalation by the user, and "inhalation" means a situation in which the substance is drawn into the user's oral cavity, nasal cavity, or lungs through the user's mouth or nose.

[0033] Throughout the specification, puff characteristic data may include information relating to puff intensity, puff interval, and number of puffs. For example, it may include, but is not limited to, information relating to the user's puff intensity, the time interval between user's puffs, the number of remaining puffs possible, and the current total number of puffs.

[0034] Figure 1 illustrates the external appearance of a holder according to one embodiment.

[0035] As illustrated in Figure 1, the holder 1 is also in stick form. The user can use the holder 1 by holding it between their fingers, like a conventional cigarette. The holder 1 is also in holder form. That is, a solid aerosol-generating material 3 is inserted into the holder 1 and heated to generate an aerosol. In some embodiments, the solid aerosol-generating material 3 is also a cigarette. The terms "cigarette" and "aerosol-generating material 3" can be used interchangeably. The operation performed when the aerosol-generating material 3 is inserted into the holder 1, and the structure of the cigarette, will be described in more detail below.

[0036] According to some embodiments, once an aerosol is generated, the generated aerosol is transmitted to the user via a filter. The filter is also provided on the holder 1 and attached to the aerosol-generating substance 3, and is not limited to the examples given above.

[0037] Furthermore, according to some embodiments, the holder 1 may include at least one output unit for providing feedback to the user. For example, it may include an LED display window 121 or an LED lamp 122, but is not limited to the examples above. A further description of the at least one output unit included in the holder 1 will be provided below.

[0038] In addition, according to some embodiments, the holder 1 can be turned on or off by user input, and can also be turned on when the user's puff is detected. The operation of the holder 1 when it is powered on is explained in Figure 2 below.

[0039] Furthermore, according to some embodiments, the holder 1 is also connected to a cradle. Details regarding the cradle will be explained in the following drawings.

[0040] Figure 2 shows a block diagram of holder 1 according to one embodiment.

[0041] The holder 1 shown in Figure 2 may include a battery 110, a control unit 120, a sensor 130, an output unit 140, and a heater 150. However, none of the components shown in Figure 2 are essential components of the holder 1. The holder 1 may be realized with more components than those shown in Figure 2, or with fewer components than those shown in Figure 2.

[0042] According to some embodiments, the control unit 120 is configured to control the overall operation of the holder 1. The control unit 120 may include, but is not limited to, a microprocessor, a microcontroller, and an IC circuit including the same.

[0043] According to some embodiments, the control unit 120 can use the sensor 130 to detect the user's puff. The control unit 120 can also acquire puff characteristic data based on the puff detection result. The control unit 120 can control the output unit 140 based on the puff characteristic data.

[0044] In some embodiments, the holder 1 may include an output unit 140. The output unit 140 may include, but is not limited to, a display such as an LED display window and LED lamp, a motor, a speaker, a temperature controller, etc. Furthermore, the holder 1 may include at least one output unit 140. For example, one holder 1 may include an LED display window, an LED lamp, and a motor.

[0045] According to some embodiments, the control unit 120 can control the output unit 140 based on puff characteristic data.

[0046] For example, the control unit 120 can predict the remaining number of puffs, recognize the user's puffs, and output the remaining number of puffs by subtracting the user's puffs from the remaining number of puffs. In other words, the control unit 120 can output the modified number of puffs. The control unit 120 can predict the remaining number of puffs based on the amount of battery power and the amount of aerosol-generating material (e.g., cigarettes).

[0047] Furthermore, according to some embodiments, the control unit 120 can control the output intensity of the vibration motor based on the remaining number of puffs. For example, the fewer the remaining number of puffs, the stronger the output of the vibration motor can be controlled. It goes without saying that the opposite is also possible, and the control unit 120 can be controlled so that the vibration motor vibrates in proportion to the remaining number of puffs.

[0048] Furthermore, the control unit 120 can also control the light intensity or flashing interval of the LED lamp based on the remaining number of puffs. For example, the fewer the remaining number of puffs, the stronger the output of the LED lamp's light. Conversely, the opposite is also possible; the control unit 120 can control the LED lamp to flash more rapidly the fewer the remaining number of puffs.

[0049] Furthermore, the control unit 120 can also control the sound output intensity or the type of sound output based on the remaining number of puffs. For example, the control unit 120 can control the sound output unit 140, such as a speaker, so that the sound output becomes stronger the fewer puffs remain. The control unit 120 can also control the sound output unit 140 to output one of a variety of sounds, such as the sound of wind or the sound of burning paper.

[0050] Furthermore, the control unit 120 can also control the case temperature outside the holder based on the temperature of the heater 150 during puffing. Even if the temperature of the heater 150 is high, the user using the holder may not be aware that the heater 150 is hot. Therefore, if the temperature of the heater 150 is excessively high, the external hizing temperature can be raised above a predetermined level to provide the user with an indication of the heater 150's temperature through a change in the case temperature.

[0051] Furthermore, the control unit 120 can provide a notification to the user each time the heater 150 is heated to a predetermined temperature or higher. When the temperature of the heater 150 is above the predetermined temperature, an optimal aerosol is generated that can satisfy the user (for example, based on aspects such as the size of the generated aerosol particles, the amount of generated aerosol, and the temperature of the generated aerosol). Therefore, when the temperature of the heater 150 is heated to a predetermined temperature or higher, the control unit 120 can control the output unit 140 and notify the user to puff, so that the user can puff with the optimal aerosol.

[0052] Furthermore, the control unit 120 can also control the output unit 140 to inform the user at predetermined intervals that puffing is possible. In other words, the control unit 120 can notify the user to puff at predetermined time intervals in order to provide the optimal aerosol.

[0053] Furthermore, according to some embodiments, the control unit 120 can also control the output unit 140 to provide a notification to the user based on the measured puff intensity or measured puff interval. Since excessively strong puffs or excessively short puff intervals make it difficult to provide a satisfactory aerosol, the control unit 120 can control the output unit 140 to provide a notification to the user if the user puffs excessively strongly or the interval between puffs is excessively short, so that the user maintains a predetermined standard for puff intensity and puff interval.

[0054] Sensor 130 can be of various types and may include at least one sensor. For example, sensor 130 may include a flow sensor and a temperature sensor.

[0055] According to some embodiments, the control unit 120 can measure the temperature of the heater 150 using a temperature sensor. This temperature sensor also measures the air temperature around the heater and determines the heater temperature using the heater's conductive track. By measuring the temperature of the heater 150, the control unit 120 can detect the user's puff.

[0056] According to some embodiments, the control unit 120 can use a flow sensor to measure the flow and / or flow rate of air, gas, and aerosols within the holder. By measuring changes in flow rate, the control unit 120 can detect user puffs. A general configuration of the control unit 120 is described in more detail in the following drawings.

[0057] In some embodiments, the heater 150 is also configured to heat the aerosol-generating substance (e.g., a cigarette or liquid) using power supplied from the battery 110. The temperature of the heater 150 is set to vary depending on the type of aerosol-generating substance. Specifically, the temperature of the heater 150 varies depending on whether the aerosol-generating substance is solid or liquid, and if the aerosol-generating substance is solid, it varies depending on the thickness and constituent materials of the aerosol-generating substance. Further details regarding the battery 110 will be explained below.

[0058] Furthermore, the heater 150 can be configured in various forms. It can be a tubular heater, a plate heater, or a needle-shaped or rod-shaped heater. Depending on its configuration, the heater 150 can heat the inside or outside of the aerosol-generating substance. The configuration of the heater 150 will be described in more detail below.

[0059] In some embodiments, the control unit 120 can control the heater 150 and the battery 110. Specifically, the control unit 120 can preheat the heater 150 to a predetermined temperature and control the battery 110 to conserve power. Furthermore, the control unit 120 can use stored profiles to control the battery 110 and the heater 150 in various modes.

[0060] For example, the control unit 120 can be controlled by dividing it into modes such as power saving mode, preheating mode, normal inhalation mode, or amplified inhalation mode, which generates more aerosol at a higher temperature than normal inhalation mode but uses more power, but is not limited to the examples given above.

[0061] According to some embodiments, the battery 110 may include at least one power source. For example, the battery 110 may include at least one battery. The battery 110 is charged by an external charger, but there are no restrictions on the charging method. Also, when the battery 110 is being charged, the holder's power may be automatically turned off or it may operate in power-saving mode.

[0062] Additionally, holder 1 may further include memory (not shown). This memory can store user information, data for temperature control such as profiles, puff characteristic data, and the like.

[0063] Figures 3 and 4 illustrate conceptual diagrams of a holder according to some embodiments.

[0064] Referring to Figure 3, the holder 1 may include an external case 170. The external case may contain a battery 110, a control unit 120, a sensor 130, an output unit 140, and a heater 150. The solid aerosol generating material 3 is inserted from outside the holder 1. The operation of each component corresponds to what was described in Figure 2, so a detailed explanation is omitted.

[0065] Figure 4 illustrates a configuration in which holder 1 further includes a liquid storage section 180, compared to Figure 3. The liquid storage section 180 contains a liquid aerosol generating material. Holder 1 in Figure 4 can generate aerosol generating material by simultaneously, alternately, and / or sequentially heating a solid aerosol generating material and a liquid aerosol generating material.

[0066] Furthermore, while holder 1 in Figure 4 can also heat the liquid aerosol generating material via a separate heater, there are no restrictions on the configuration of the heater used to heat the liquid aerosol generating material and the solid aerosol generating material. In the following drawings, further conceptual diagrams of holders are additionally illustrated and explained.

[0067] Figure 5 illustrates a control method for a holder that senses puffing and controls the output unit, according to one embodiment.

[0068] In step 501, the holder can use sensors to detect the user's puff. The holder can use a flow sensor and a temperature sensor to detect the user's puff.

[0069] According to some embodiments, the holder can detect the user's puff by using a flow sensor to check the amount of air flowing into the holder or the amount of gas flowing out of the holder.

[0070] Furthermore, the holder can detect the user's puff by using a temperature sensor to measure the heater temperature and confirming the change in the heater temperature. In addition, the holder can also recognize the user's puff using a pressure sensor, but the methods by which the holder can detect the user's puff are not limited to the examples given above.

[0071] In step 503, the holder can acquire puff characteristic data based on the sensing results.

[0072] According to some embodiments, the puff characteristic data may include information relating to puff intensity, puff interval, and number of puffs. Specifically, the puff characteristic data may include information relating to the user's puffing pressure (puff strength, intensity), the time interval between the first and second puffs, the number of remaining possible puffs, and the current total number of puffs. The current total number of puffs refers to the number of puffs calculated since the holder was turned on or the aerosol-generating substance was inserted, but is not limited to the examples given above.

[0073] According to some embodiments, the holder can sense at least one puff press by the user and acquire information related to the puff's intensity, the interval between puff presses, the number of puff presses, and so on.

[0074] In step 505, the holder can control at least one output unit based on puff characteristic data.

[0075] According to some embodiments, the holder can control the output unit based on the remaining number of puffs. For example, the holder can control the vibration motor to vibrate weakly if the remaining number of puffs is greater than or equal to a predetermined number, and control the vibration motor to vibrate strongly if the remaining number of puffs is less than or equal to a predetermined number.

[0076] In addition, the holder can be controlled to either shorten the blinking interval of the LED lamp or increase the light intensity of the LED lamp as the number of remaining puffs decreases.

[0077] Furthermore, according to some embodiments, the holder can also control the output unit based on the puff intensity. For example, the holder can be controlled so that the puff intensity is proportional to the vibration intensity of the vibration motor. The method by which the holder controls at least one output unit based on puff characteristic data is not limited and may include the method described in Figure 2.

[0078] Figure 6 illustrates an output mode control method based on the remaining number of puffs possible according to one embodiment.

[0079] In step 601, the holder can use a sensor to detect the user's puff. This corresponds to what was mentioned earlier, so a detailed explanation will be omitted.

[0080] In step 603, the holder can determine whether the remaining number of puffs is below a critical value.

[0081] According to some embodiments, the holder can predict the remaining number of possible puffs. The holder can predict the remaining number of possible puffs based on the amount of aerosol-generating material, the amount of battery, a reference puff intensity, the number of puffs by the user, and so on.

[0082] Furthermore, the number of remaining puffs can also be changed by the user's puff intensity and puff interval. For example, assuming that the holder initially predicts 8 remaining puffs based on the amount of aerosol-generating material and battery, after 2 puffs, the number of remaining puffs can be predicted as 5 instead of 6, depending on the user's puff intensity and puff interval. In other words, the holder can calculate the number of remaining puffs based on puff characteristic data.

[0083] According to some embodiments, the holder can determine whether the calculated number of remaining puffs is above or below a critical value. The holder can also output the calculated number of remaining puffs. The output of the holder can be displayed via an LED display window or an LED lamp.

[0084] In stage 605, the holder can maintain the output mode if the remaining number of puffs is equal to or greater than a critical value. The output mode refers to the mode in which the holder controls at least one output unit.

[0085] For example, output mode 1 means a single-stage illumination mode for the LED lamp and a single-stage vibration mode for the vibration motor, and output mode 2 means a double-stage illumination mode for the LED lamp and a double-stage vibration mode for the vibration motor, but is not limited to the above examples.

[0086] In other words, the output mode refers to a combination of modes in which at least one output unit contained within the holder outputs light. Specifically, the light emission mode of the LED lamp refers to a predetermined LED flashing intensity and flashing interval, and the vibration mode of the vibration motor refers to a predetermined vibration intensity and vibration interval, but is not limited to the examples given above.

[0087] According to some embodiments, the holder can maintain the output mode when the number of remaining puffs is greater than or equal to a critical value. In other words, the holder does not change the output mode. For example, the holder can maintain the output mode at one stage when the number of remaining puffs is four or more.

[0088] In step 607, the holder can determine whether the number of remaining puffs is 0 or not, if the number of remaining puffs is less than or equal to a critical value. For example, if it is determined that the number of remaining puffs is 4 or less, the holder can confirm whether the number of remaining puffs is 0 or not.

[0089] In step 609, the holder can change the output mode if the remaining number of puffs is not zero. For example, if the remaining number of puffs is not zero but less than four, the holder can change the output mode to two levels.

[0090] Furthermore, in step 611, the holder can stop the output mode if the remaining number of puffs is 0. That is, the holder can stop the LED from flashing and also stop the vibration of the vibration motor.

[0091] Here, the holder can change the output mode rather than completely stopping it, and can use a different output unit than the one used in the existing output mode to indicate the need to remove or replace aerosol-generating substances or to charge the holder. For example, if the number of remaining puffs is 0, the holder can stop using the LED lamp and vibration motor and instead use the LED display window to inform the user that the aerosol-generating substances need to be removed or replaced or the holder needs to be charged.

[0092] Figure 7 illustrates the change in heater temperature due to puffing in one embodiment.

[0093] As mentioned above, the act of a user inhaling an aerosol generated through a holder can be described as puffing.

[0094] According to some embodiments, during puffing, the holder does not only transmit the aerosol generated from the aerosol-generating substance to the user via heating, but rather the generated aerosol is mixed with the air flowing in to the outside through the holder and then transmitted to the user.

[0095] According to some embodiments, the holder can sense the user's puff in a variety of ways. For example, the holder can sense the user's puff by using a pressure sensor to measure changes in pressure within the holder. However, the holder can also sense the user's puff by measuring the heater temperature without having a separate pressure sensor.

[0096] The heater temperature varies with each puff by the user. During each puff, air at a lower temperature than the heater flows in from the holder, causing the heater temperature to drop. Referring to Figure 7, it can be seen that the heater temperature is lower during the first puff (701) when the user first inhales the aerosol.

[0097] Subsequently, the holder supplies power to the heater, further raising the heater temperature to a predetermined temperature. During the second puff (702) and third puff (703), the heater temperature decreases, just as during the first puff (701). The holder measures the heater temperature and can sense that a puff has occurred when the heater temperature decreases. Also, since the heater temperature has decreased during a puff, the holder can supply power to the heater to further raise it to a predetermined temperature.

[0098] Figure 8 illustrates the change in flow rate due to the puff in one embodiment.

[0099] As mentioned above, during puffing, the aerosol generated from the aerosol-generating substance is not the only thing transmitted to the user via the heating of the holder; rather, the generated aerosol is mixed with the air flowing in from the outside through the holder and then transmitted to the user. Therefore, the holder can recognize the user's puffing by detecting changes in the flow rate within the holder.

[0100] The flow rate differs with each puff by the user. During a puff, air flows in from outside the holder, increasing the flow rate inside the holder. Referring to Figure 8, it can be seen that the flow rate increases during the first puff (801) when the user first inhales the aerosol.

[0101] During the second puff (802) and third puff (803), the flow rate increases in the same way as during the first puff (801). The holder can measure the change in flow rate and sense that a puff has occurred when the flow rate increases. Therefore, the holder can sense a puff based on changes in flow rate and temperature, without the need for a separate pressure sensor. The holder can also sense the intensity of the puff based on the degree of change in flow rate and temperature.

[0102] Figures 9A to 9C illustrate LED lamp output control based on the remaining number of puffs possible according to some embodiments.

[0103] As mentioned above, holder 1 can have different output modes depending on the remaining number of puffs possible.

[0104] As shown in Figures 9A to 9C, when the remaining number of puffs is 5, 3, and 1, the holder 1 can control the blinking hue, blinking intensity, and blinking interval of the LED lamp 901 to be different. The LED lamp 901 in Figure 9 is the same lamp as the LED lamp 122 in Figure 1. Also, when the remaining number of puffs is 0, the holder 1 can be controlled so that the LED lamp does not blink.

[0105] Additionally, holder 1 can control the LED lamp 901 to blink only when puffed. Furthermore, holder 1 can control the blinking intensity of the LED lamp 901 and output sound to interact with user input via the power button or input button.

[0106] Furthermore, holder 1 can also control an LED lamp or a vibration motor to inform the user of the insertion or removal of an aerosol-generating substance. In other words, at least one output unit included in holder 1 is also controlled to provide notifications to the user in order to provide feedback on the user's puffs for interaction with the user.

[0107] Figure 10 illustrates the correlation between puff strength and vibration strength in some embodiments.

[0108] According to some embodiments, the user's puffing intensity and the vibration intensity of the vibration motor in the holder can be proportional. In other words, the vibration intensity changes depending on how hard the user puffs.

[0109] As illustrated in Figure 10, when the vibration intensity is adjusted according to the user's puffing strength, the user can be immediately provided with feedback on the puffing strength. Providing the optimal aerosol requires puffing with the appropriate intensity, and by providing feedback on puffing strength to the user through vibration intensity, the holder can guide the user to puff with the appropriate intensity.

[0110] Here, contrary to what is illustrated in Figure 10, it is also possible to set the vibration intensity to decrease as the puff intensity increases, and it goes without saying that there are no limitations on the relationship between vibration intensity and puff intensity. In other words, any method that can provide feedback to the user is sufficient.

[0111] Figure 11 is a diagram illustrating an example of an aerosol generation apparatus.

[0112] Referring to Figure 11, the aerosol generator 1 (hereinafter referred to as the holder) includes a battery 110, a control unit 120, and a heater 2130. The holder 1 also includes an internal space formed by the case 2140. A cigarette is inserted into the internal space of the holder 1. The holder 1 shown in Figure 11 is also another embodiment of the holder 1 described above, and its configuration corresponds in part or in whole to that of the holder 1 described above.

[0113] The holder 1 shown in Figure 11 only shows the components related to this embodiment. Therefore, a person skilled in the art related to this embodiment will understand that other general-purpose components may be included in the holder 1 in addition to the components shown in Figure 11.

[0114] When a cigarette is inserted into holder 1, holder 1 heats heater 2130. The aerosol-generating material in the cigarette is heated by the heated heater 2130, causing an aerosol to be generated. The generated aerosol is transmitted to the user through the cigarette's filter. However, holder 1 can also heat heater 2130 even when a cigarette is not inserted into holder 1.

[0115] Case 2140 is separated from holder 1. For example, a user can separate case 2140 from holder 1 by rotating it clockwise or counterclockwise.

[0116] Furthermore, the diameter of the hole formed by the end 2141 of the case 2140 is made smaller than the diameter of the space formed by the case 2140 and the heater 2130, so that it can act as a guide for the cigarette inserted into the holder 1.

[0117] The battery 110 supplies the power used to operate the holder 1. For example, the battery 110 can supply power to heat the heater 2130 and supply the power necessary for the control unit 120 to operate. The battery 110 can also supply the power necessary for the operation of output units provided in the holder 1, such as the display, sensors, and motors.

[0118] Battery 110 is a lithium iron phosphate (LiFePO4) battery, but it is not limited to the examples mentioned above. For example, battery 110 could be a lithium cobalt oxide (LiCoO2) battery, a lithium titanate battery, etc.

[0119] Furthermore, while battery 110 is cylindrical with a diameter of 10 mm and a length of 37 mm, it is not limited to this. Battery 110 has a capacity of 120 mAh or more and is either a rechargeable battery or a single-use battery. For example, if battery 110 is rechargeable, its charge rate (C-rate) is 10C and its discharge rate (C-rate) is 16C or 20C, but it is not limited to these. In addition, for stable use, battery 110 is manufactured so that more than 80% of its total capacity is maintained even after 8,000 charge-discharge cycles.

[0120] Here, whether battery 110 is fully charged or completely discharged is also determined by the level of power stored in battery 110 relative to its total capacity. For example, if the power stored in battery 110 is 95% or more of its total capacity, battery 110 is judged to be fully charged. Also, if the power stored in battery 110 is 10% or less of its total capacity, battery 110 is judged to be completely discharged. However, the criteria for determining whether battery 110 is fully charged or completely discharged are not limited to the examples given above.

[0121] 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 raises the temperature of the aerosol-generating material inside the cigarette. The heater 2130 also corresponds to the heater 150 mentioned above.

[0122] The heater 2130 also has a shape that combines a cylinder and a cone. For example, the heater 2130 has a cylindrical shape with a diameter of approximately 2 mm and a length of approximately 23 mm, and the end 2131 of the heater 2130 is finished at an acute angle, but is not limited to that. In other words, the heater 2130 is in any form that is inserted inside a cigarette, without limitation. Also, the heater 2130 can be heated only in part. For example, assuming that the length of the heater 2130 is 23 mm, only 12 mm from the end 2131 of the heater 2130 will be heated, and the rest of the heater 2130 will not be heated.

[0123] The heater 2130 is also an electrical resistance heater. For example, the heater 2130 includes an electrical conductive track, and the heater 2130 is heated when an electric current flows through the electrical conductive track.

[0124] For stable operation, the heater 2130 is supplied with power according to specifications of 3.2V, 2.4A, and 8W, but is not limited to these. For example, when power is supplied to the heater 2130, its surface temperature rises to over 400°C. Within 15 seconds of power being supplied to the heater 2130, its surface temperature rises to approximately 350°C.

[0125] The holder 1 is equipped with a separate temperature sensing sensor. Alternatively, the holder 1 may not be equipped with a temperature sensing sensor, and the heater 2130 may perform the role of a temperature sensing sensor. For example, the heater 2130 may further include a second electrically conductive track for temperature sensing in addition to the first electrically conductive track for heat generation.

[0126] For example, the resistance (R) can be determined by measuring the voltage across the second electrically conductive track and the current flowing through the second electrically conductive track. At this time, the temperature (T) of the second electrically conductive track can be determined by the following equation 1. The temperature sensing sensor is also one embodiment of the sensor 130 described above.

[0127]

number

[0128] In Equation 1, R represents the current resistance of the second conductive track, R0 represents the resistance at temperature T0 (e.g., 0°C), and α represents the temperature coefficient of resistance of the second conductive track. Conductive materials (e.g., metals) have their own inherent temperature coefficients of resistance, but α is predetermined by the conductive material constituting the second conductive track. Therefore, once the resistance (R) of the second conductive track is determined, the temperature (T) of the second conductive track is calculated using Equation 1.

[0129] The heater 2130 also comprises at least one electrically conductive track (a first electrically conductive track and a second electrically conductive track). For example, the heater 2130 may also consist of two first electrically conductive tracks and one or two second electrically conductive tracks, but is not limited to these.

[0130] The electrically conductive track includes an electrically resistant material. For example, the electrically conductive track may also be made from a metallic material. In other examples, the electrically conductive track may also be made from an electrically conductive ceramic material, carbon, a metal alloy, or a composite material of a ceramic material and a metal.

[0131] Furthermore, holder 1 may include both an electrically conductive track and a temperature sensing sensor that function as a temperature sensing sensor.

[0132] The control unit 120 controls the overall operation of the holder 1. Specifically, the control unit 120 controls the operation of not only the battery 110 and heater 2130, but also other components included in the holder 1. The control unit 120 can also check the state of each component of the holder 1 and determine whether or not the holder 1 is in an operational state.

[0133] The control unit 120 includes at least one processor. This processor can also be embodied by an array of numerous logic gates, or by a combination of a general-purpose microprocessor and memory in which a program executed by the microprocessor is stored. It can also be embodied by other forms of hardware, as will be understood by those skilled in the art to which this embodiment belongs.

[0134] For example, the control unit 120 can control the operation of the heater 2130. The control unit 120 can control the amount of power supplied to the heater 2130 and the duration of power supply so that the heater 2130 is heated to a predetermined temperature or maintained at an appropriate temperature. The control unit 120 can also check the status of the battery 110 (for example, the remaining charge of the battery 110) and generate an alert signal if necessary.

[0135] Furthermore, the control unit 120 can confirm the presence or absence of the user's puff and the puff's intensity, and can count the number of puffs. The control unit 120 can also continuously monitor the operating time of the holder 1. In addition, the control unit 120 can confirm whether the cradle 2, described later, is coupled to the holder 1, and can control the operation of the holder 1 by coupling or uncoupling the cradle 2 and the holder 1.

[0136] On the other hand, holder 1 may further include general-purpose components in addition to the battery 110, control unit 120, and heater 2130.

[0137] For example, holder 1 may include a display capable of outputting visual information, or a motor for outputting tactile information. As an example, if holder 1 includes a display, the control unit 120 can transmit to the user via the display information relating to the status of holder 1 (e.g., whether the holder is usable), information relating to heater 2130 (e.g., preheating start, preheating progress, preheating completion), information relating to battery 110 (e.g., remaining capacity of battery 110, usable status), information relating to resetting holder 1 (e.g., reset time, reset progress, reset completion), information relating to cleaning holder 1 (e.g., cleaning time, cleaning required, cleaning progress, cleaning completion), information relating to charging holder 1 (e.g., charging required, charging progress, charging completion), information relating to puffing (e.g., number of puffs, puff completion warning), or safety-related information (e.g., elapsed usage time). As another example, if the holder 1 includes a motor, the control unit 120 can use the motor to generate a vibration signal and thereby transmit the aforementioned information to the user.

[0138] Furthermore, holder 1 may include at least one input device (e.g., a button) and / or terminals connected to cradle 2, which allow the user to control the functions of holder 1. For example, the user can use the input device of holder 1 to perform a variety of functions. By adjusting the number of times the user presses the input device (e.g., once, twice, etc.) or the duration for which the input device is pressed (e.g., 0.1 seconds, 0.2 seconds, etc.), the user can perform a desired function from among the multiple functions of holder 1. When the user activates the input device, holder 1 can perform functions such as preheating the heater 2130, adjusting the temperature of the heater 2130, cleaning the space where the cigarette is inserted, checking whether holder 1 is in an operational state, displaying the remaining charge (available power) of battery 110, and resetting holder 1. However, the functions of holder 1 are not limited to the examples described above.

[0139] Furthermore, holder 1 may include a puff detection sensor, a temperature detection sensor, and / or a cigarette insertion detection sensor. For example, the puff detection sensor may also be embodied by a general pressure sensor, and the cigarette insertion detection sensor may also be embodied by a general capacitive or resistive sensor. In addition, holder 1 may be constructed in such a way that external air flows in and out even when a cigarette is inserted.

[0140] Figures 12A and 12B are drawings illustrating an example of a holder from various angles.

[0141] Figure 12A is a diagram illustrating an example of holder 1 viewed from a first direction. As shown in Figure 12A, holder 1 can be manufactured in a cylindrical shape, but is not limited to that. The case 2140 of holder 1 can also be separated by user action, and a cigarette is inserted into the end 2141 of case 2140. Holder 1 also includes a button 2150 that allows the user to control holder 1, and a display 2160 that outputs an image. Case 2140 is also one embodiment of the case described above.

[0142] Figure 12B is a diagram illustrating an example of holder 1 viewed from a second direction. Holder 1 may include terminals 2170 that are connected to cradle 2. By connecting terminals 2170 of holder 1 to terminals 2260 of cradle 2, the battery 110 of holder 1 is charged by the power supplied by the battery 210 of cradle 2. In addition, holder 1 can also be operated by the power supplied by the battery 210 of cradle 2 via terminals 2170 and 2260, and communication (sending and receiving of signals) is possible between holder 1 and cradle 2. For example, terminal 2170 may be composed of four micropins, but is not limited to that.

[0143] Figure 13 is a diagram illustrating an example of a cradle.

[0144] Referring to Figure 13, the cradle 2 includes a battery 210 and a control unit 220. The cradle 2 also includes an internal space 2230 into which the holder 1 is inserted. For example, the internal space 2230 is also formed on one side of the cradle 2. Therefore, even if the cradle 2 does not include a separate lid, the holder 1 is inserted into and secured in the cradle 2.

[0145] The cradle 2 shown in Figure 13 only illustrates the components related to this embodiment. Therefore, a person skilled in the art related to this embodiment will understand that, in addition to the components shown in Figure 13, other general-purpose components may also be included in the cradle 2.

[0146] Battery 210 supplies the power used to operate cradle 2. Battery 210 can also supply power to charge battery 110 in holder 1. For example, when holder 1 is inserted into cradle 2 and terminal 2170 of holder 1 is connected to terminal 2260 of cradle 2, battery 210 in cradle 2 can supply power to battery 110 in holder 1.

[0147] Furthermore, when holder 1 and cradle 2 are connected, battery 210 can supply the power used for holder 1 to operate. For example, if terminal 2170 of holder 1 is connected to terminal 2260 of cradle 2, holder 1 can operate using the power supplied by battery 210 of cradle 2, regardless of whether or not battery 110 of holder 1 is discharged.

[0148] The examples of battery types 210 are the same as the example of battery 110 described with reference to Figure 11. The capacity of battery 210 can be 3,000mAh or more. However, the capacity of battery 210 is not limited to the examples mentioned above.

[0149] The control unit 220 controls the overall operation of the cradle 2. The control unit 220 can control the operation of all components of the cradle 2. In addition, the control unit 220 can determine whether the holder 1 and the cradle 2 are coupled or not, and can control the operation of the cradle 2 by coupling or uncoupling the cradle 2 and the holder 1.

[0150] For example, when holder 1 and cradle 2 are coupled, the control unit 220 can charge battery 110 or heat heater 2130 by supplying power from battery 210 to holder 1. Therefore, even when the battery 110 has a low charge, the user can couple holder 1 and cradle 2 and smoke continuously.

[0151] The control unit 120 includes at least one processor. This processor can also be embodied by an array of numerous logic gates, or by a combination of a general-purpose microprocessor and memory in which a program executed by that microprocessor is stored. It can also be embodied by other forms of hardware, as will be understood by those skilled in the art to which this embodiment belongs.

[0152] On the other hand, the cradle 2 may include general-purpose components in addition to the battery 210 and the control unit 220. For example, the cradle 2 may include a display capable of outputting visual information. For example, if the cradle 2 includes a display, the control unit 220 can transmit to the user information related to the battery 220 (e.g., remaining capacity of the battery 220, availability, etc.), information related to the reset of the cradle 2 (e.g., reset time, reset in progress, reset completed, etc.), information related to cleaning the holder 1 (e.g., cleaning time, cleaning required, cleaning in progress, cleaning completed, etc.), and information related to the charging of the cradle 2 (e.g., charging required, charging in progress, charging completed, etc.) by generating signals that can be displayed on the display. The display is also one embodiment of the output unit 140 described above.

[0153] The cradle 2 may also include at least one input device (e.g., a button) that allows the user to control the functions of the cradle 2, a terminal 2260 that connects to the holder 1, and / or an interface (e.g., a USB port) for charging the battery 210.

[0154] For example, the user can use the input device of Cradle 2 to perform a variety of functions. By adjusting the number of times the user presses the input device or the duration of the press, the user can perform the desired function from among the multiple functions of Cradle 2. When the user activates the input device, Cradle 2 can also perform functions such as preheating the heater 2130 of Holder 1, adjusting the temperature of the heater 2130 of Holder 1, cleaning the space in Holder 1 where the cigarette is inserted, checking whether Cradle 2 is in an operational state, displaying the remaining charge (available power) of the battery 210 of Cradle 2, and resetting Cradle 2. However, the functions of Cradle 2 are not limited to the examples given above.

[0155] Figures 14A and 14B are diagrams illustrating an example of a cradle from various angles.

[0156] Figure 14A is a diagram illustrating an example of the cradle 2 viewed from a first direction. One side of the cradle 2 has a space 2230 into which the holder 1 is inserted. The holder 1 is inserted into and secured to the cradle 2 even if the cradle 2 does not include a separate fixing means such as a lid. The cradle 2 also includes a button 2240 that the user can use to control the cradle 2, and a display 2250 that outputs an image.

[0157] Figure 14B is a diagram illustrating an example of the cradle 2 viewed from a second direction. The cradle 2 may include a terminal 2260 that is coupled to the inserted holder 1. By coupling terminal 2260 with terminal 2170 of holder 1, the battery 110 of holder 1 is charged by the power supplied by the battery 210 of cradle 2. In addition, the holder 1 can also be operated by the power supplied by the battery 210 of cradle 2 via terminals 2170 and 2260, enabling signal transmission and reception between holder 1 and cradle 2. For example, terminal 2260 may, but is not limited to, four micropins.

[0158] As described with reference to Figures 11 to 14B, holder 1 is inserted into the internal space 2230 of cradle 2. Furthermore, holder 1 is fully inserted into cradle 2 and can be tilted even while inserted into cradle 2. An example of holder 1 being inserted into cradle 2 will be described below with reference to Figures 15 and 17B.

[0159] Figure 15 is a diagram illustrating an example of how the holder is inserted into the cradle.

[0160] Referring to Figure 15, an example of holder 1 being inserted into cradle 2 is illustrated. Since the space 2230 into which holder 1 is inserted is located on one side of cradle 2, the inserted holder 1 is not exposed to the outside by the other side of cradle 2. Therefore, cradle 2 does not need to include other components (e.g., a lid) to prevent holder 1 from being exposed to the outside.

[0161] Cradle 2 also includes at least one fastening member 2271, 2272 to increase the bonding strength with holder 1. Holder 1 also includes at least one fastening member 2181. Here, fastening members 2181, 2271, 2272 can also be magnets, but are not limited to that. For the sake of explanation, Figure 15 shows holder 1 including one fastening member 2181 and cradle 2 including two fastening members 2271, 2272, but the number of fastening members 2181, 2271, 2272 is not limited to that.

[0162] The holder 1 may include a fastening member 2181 in a first position, and the cradle 2 may include fastening members 2271 and 2272 in a second position and a third position, respectively. In this case, the first position and the third position are also positions that face each other when the holder 1 is inserted into the cradle 2.

[0163] The inclusion of fastening members 2181, 2271, and 2272 in holder 1 and cradle 2 further strengthens the bond between holder 1 and cradle 2, even when holder 1 is inserted into one side of cradle 2. In other words, the inclusion of fastening members 2181, 2271, and 2272 in holder 1 and cradle 2, in addition to terminals 2170 and 2260, further strengthens the bond between holder 1 and cradle 2. Therefore, even without a separate component (e.g., a lid) in cradle 2, the inserted holder 1 will not easily separate from cradle 2.

[0164] Furthermore, if the terminals 2170, 2260 and / or fastening members 2181, 2271, 2272 determine that the holder 1 is fully inserted into the cradle 2, the control unit 220 can use the power from the battery 210 to charge the battery 110 of the holder 1.

[0165] Figure 16 is a diagram illustrating an example of the holder being tilted while inserted into the cradle.

[0166] Referring to Figure 16, the holder 1 is tilted inside the cradle 2. Here, this tilt means that the holder 1 is tilted by a certain angle from the state in which it is inserted into the cradle 2.

[0167] As illustrated in Figure 15, when holder 1 is fully inserted into cradle 2, the user cannot smoke. In other words, when holder 1 is fully inserted into cradle 2, no cigarette can be inserted into holder 1. Therefore, when holder 1 is fully inserted into cradle 2, the user cannot smoke.

[0168] As illustrated in Figure 16, when holder 1 is tilted, the end 2141 of holder 1 is exposed to the outside. Thus, the user can insert a cigarette into the end 2141 and inhale (smoke) the generated aerosol. The tilt angle θ is set to ensure a sufficient angle so that the cigarette does not break or get damaged when it is inserted into the end 2141 of holder 1. For example, holder 1 is tilted to the minimum angle, or a larger angle, that exposes the entire cigarette insertion hole contained in the end 2141 to the outside. For example, the range of the tilt angle θ can be greater than 0° and less than or equal to 180°, and preferably between 10° and 90°. More preferably, the range of the tilt angle θ can be between 10° and 20°, between 10° and 30°, between 10° and 40°, between 10° and 50°, or between 10° and 60°.

[0169] Furthermore, even when holder 1 is tilted, terminal 2170 of holder 1 and terminal 2260 of cradle 2 remain connected to each other. Therefore, the heater 2130 of holder 1 is also heated by the power supplied by battery 210 of cradle 2. Consequently, even when the battery 110 of holder 1 has little or no charge remaining, holder 1 can use battery 210 of cradle 2 to generate aerosols.

[0170] Figure 16 illustrates an example in which holder 1 includes one fastening member 2182 and cradle 2 includes two fastening members 2273 and 2274. For example, the positions of fastening members 2182, 273, and 2274 are as described with reference to Figure 15. If we assume that fastening members 2182, 273, and 2274 are magnets, then the magnetic strength of fastening member 2274 will be greater than that of fastening member 2273. Therefore, even when holder 1 is tilted, fastening members 182 and 2274 prevent holder 1 from being completely separated from cradle 2.

[0171] Furthermore, if the terminals 2170, 2260 and / or the fastening members 2182, 273, 2274 determine that the holder 1 has been tilted, the control unit 220 can use the power from the battery 210 to heat the heater 2130 of the holder 1 or charge the battery 110.

[0172] Figures 17A and 17B are diagrams illustrating an example in which the holder is inserted into the cradle.

[0173] Figure 17A illustrates an example in which the holder 1 is fully inserted into the cradle 2. When the holder 1 is fully inserted into the cradle 2, the internal space 2230 of the cradle 2 is also designed to be sufficiently large to minimize user contact with the holder 1. Once the holder 1 is fully inserted into the cradle 2, the control unit 220 supplies power from the battery 210 to the holder 1 so that the battery 110 of the holder 1 is charged.

[0174] Figure 17B illustrates an example in which the holder 1 is tilted while inserted into the cradle 2. When the holder 1 is tilted, the control unit 220 supplies power from the battery 210 to the holder 1 so that the battery 110 of the holder 1 is charged or the heater 2130 of the holder 1 is heated.

[0175] Figure 18 is a flowchart illustrating an example of how the holder and cradle operate.

[0176] The method for generating the aerosol shown in Figure 18 consists of steps processed sequentially in the holder 1 shown in Figure 11 or the cradle 2 shown in Figure 13. Therefore, even if some details are omitted below, it can be seen that the information described above regarding the holder 1 shown in Figure 11 and the cradle 2 shown in Figure 13 also applies to the method shown in Figure 18.

[0177] At step 2710, it is determined whether or not the holder 1 has been inserted into the cradle 2. For example, the control unit 120 can determine whether or not the holder 1 has been inserted into the cradle 2 by checking whether or not the terminals 2170 and 2260 of the holder 1 and the cradle 2 are connected to each other, and / or whether or not the fastening members 2181, 2271, and 2272 are operating.

[0178] If holder 1 is inserted into cradle 2, the process proceeds to step 2720; if holder 1 is separated from cradle 2, the process proceeds to step 2730.

[0179] At step 2720, the cradle 2 determines whether or not the holder 1 has been tilted. For example, the control unit 220 can determine whether or not the holder 1 has been tilted by checking whether or not the terminals 2170 and 2260 of the holder 1 and the cradle 2 are connected to each other, and / or whether or not the fastening members 2182, 273, and 2274 are operating.

[0180] In step 2720, it was explained that the cradle 2 determines the tilt of the holder 1, but this is not the only way it can determine this. In other words, the tilt of the holder 1 can also be determined by the control unit 120 of the holder 1.

[0181] If holder 1 is tilted, the process proceeds to step 2740; if holder 1 is not tilted (i.e., holder 1 is fully inserted into cradle 2), the process proceeds to step 2770.

[0182] At step 2730, the holder 1 determines whether or not the operating conditions for holder 1 are met. For example, the control unit 120 can determine whether or not the operating conditions are met by checking the remaining charge of the battery 110 and whether or not the other components of holder 1 can operate normally.

[0183] If the usage conditions for holder 1 are met, proceed to step 2740; otherwise, terminate the procedure.

[0184] At step 2740, the holder 1 informs the user that it is ready for use. For example, the control unit 120 can output an image to the display of the holder 1 indicating that it is ready for use, and can also control the motor of the holder 1 and generate a vibration signal.

[0185] The heater 2130 is heated in 2750 steps. For example, when holder 1 is separated from cradle 2, the heater 2130 is also heated by the power of holder 1's battery 110. As another example, when holder 1 is tilted, the heater 2130 is also heated by the power of cradle 2's battery 210.

[0186] The control unit 120 of holder 1, or the control unit 220 of cradle 2, can monitor the temperature of heater 2130 in real time and adjust the amount of power supplied to heater 2130 and the duration for which power is supplied to heater 2130. For example, the control units 120 and 220 can monitor the temperature of heater 2130 in real time via a temperature sensing sensor included in holder 1 or via the electrically conductive track of heater 2130.

[0187] In step 2760, holder 1 performs the aerosol generation mechanism. For example, control units 120 and 220 can monitor the temperature of heater 2130, which changes as the user performs puffs, and adjust the amount of power supplied to heater 2130 or interrupt the power supply to heater 2130. Control units 120 and 220 can also count the number of puffs performed by the user and, once a certain number of puffs (e.g., 1,500) is reached, can output information indicating that the holder needs to be cleaned.

[0188] In step 2770, the cradle 2 charges the holder 1. For example, the control unit 220 can charge the holder 1 by supplying power from the cradle 2's battery 210 to the holder 1's battery 110.

[0189] On the other hand, the control units 120 and 220 can also stop the operation of holder 1 based on the number of puffs taken by the user or the operating time of holder 1. An example of how the control units 120 and 220 stop the operation of holder 1 will be described below with reference to Figure 19.

[0190] Figure 19 is a flowchart illustrating another example of how the holder works.

[0191] The method for generating the aerosol shown in Figure 19 consists of steps processed sequentially in the holder 1 shown in Figure 11 and the cradle 2 shown in Figure 3. Therefore, even if some details are omitted below, it can be seen that the information described above regarding the holder 1 shown in Figure 11 or the cradle 2 shown in Figure 3 also applies to the method shown in Figure 19.

[0192] In step 2810, the control units 120 and 220 determine whether or not the user has puffed. For example, the control units 120 and 220 can determine whether or not the user has puffed via the puff detection sensor included in the holder 1.

[0193] In step 2820, an aerosol is generated by the user's puff. As explained with reference to Figure 18, the control units 120 and 220 can adjust the power supplied to the heater 2130 based on the user's puff and the temperature of the heater 2130. The control units 120 and 220 also count the number of puffs taken by the user.

[0194] At step 2830, the control units 120 and 220 determine whether the user's puff count is equal to or greater than the puff limit. For example, assuming the puff limit is set to 14, the control units 120 and 220 determine whether the counted puff count is 14 or greater.

[0195] On the other hand, if the user's puff count approaches the puff limit (for example, if the user has puffed 12 times), the control units 120 and 220 can output a warning signal via the display or vibration motor.

[0196] If the user's puff count exceeds the puff limit, the game proceeds to stage 2850; if the user's puff count is less than the puff limit, the game proceeds to stage 2840.

[0197] At step 2840, the control units 120 and 220 determine whether the time the holder 1 has been operating is equal to or greater than the operating time limit. Here, the time the holder 1 has been operating refers to the cumulative time from the time the holder started operating until the present. For example, assuming that the operating time limit is set to 10 minutes, the control units 120 and 220 determine whether the holder 1 has been operating for 10 minutes or more.

[0198] On the other hand, if the operating time of holder 1 approaches the operating limit time (for example, if holder 1 has been operating for 8 minutes), the control units 120 and 220 can output a warning signal via the display or vibration motor.

[0199] If holder 1 has been operating for longer than the operating time limit, the process proceeds to step 2850. If the operating time of holder 1 is less than the operating time limit, the process proceeds to step 2820.

[0200] At step 2850, the control units 120 and 220 forcibly terminate the holder's operation. In other words, the control units 120 and 220 stop the holder's aerosol generation mechanism. For example, the control units 120 and 220 can forcibly terminate the holder's operation by cutting off the power supplied to the heater 2130.

[0201] Figure 20 is a flowchart illustrating an example of how the cradle operates.

[0202] The flowchart shown in Figure 20 is composed of the stages processed chronologically in Cradle 2 shown in Figure 3. Therefore, even if some details are omitted below, the information described above regarding Cradle 2 shown in Figure 3 also applies to the flowchart in Figure 20.

[0203] Although not shown in Figure 20, the operation of the cradle 2 described below can also be performed regardless of whether or not the holder 1 is inserted into the cradle 2.

[0204] At step 2910, the control unit 220 of the cradle 2 determines whether or not button 2240 has been pressed. If button 2240 has been pressed, the process proceeds to step 2920; otherwise, the process proceeds to step 2930.

[0205] In 2920 steps, the cradle 2 displays the battery status. For example, the control unit 220 can output information related to the current state of the battery 210 (e.g., remaining charge) to the display 2250.

[0206] In step 2930, the control unit 220 of the cradle 2 determines whether or not a cable has been connected to the cradle 2. For example, the control unit 220 determines whether or not a cable has been connected to an interface included in the cradle 2 (e.g., a USB port). If a cable has been connected to the cradle 2, the process proceeds to step 2940; otherwise, the procedure ends.

[0207] In step 2940, the cradle 2 performs a charging operation. For example, the cradle 2 uses power supplied via the connected cable to charge the battery 210.

[0208] As explained with reference to Figure 11, a cigarette is inserted into holder 1. The cigarette contains an aerosol-generating substance, and an aerosol is generated by the heated heater 2130.

[0209] The following describes examples of cigarettes inserted into holder 1, with reference to Figures 21 to 23F.

[0210] Figure 21 is a diagram illustrating an example of a cigarette being inserted into a holder.

[0211] Referring to Figure 21, the cigarette 3 is inserted into the holder 1 via the end 2141 of the case 2140. Once the cigarette 3 is inserted, the heater 2130 is located inside the cigarette 3. Thus, the heated heater 2130 heats the aerosol-generating material in the cigarette 3, thereby generating an aerosol.

[0212] Cigarette 3 is similar to a typical combustible cigarette. For example, cigarette 3 is divided into a first part 3310 containing an aerosol-generating substance and a second part 3320 containing a filter, etc. On the other hand, in one embodiment, cigarette 3 may also contain an aerosol-generating substance in the second part 3320. For example, an aerosol-generating substance made in the form of granules or capsules may also be inserted into the second part 3320.

[0213] The entire first part 3310 is inserted into the holder 1, while the second part 3320 is exposed to the outside. Alternatively, only a portion of the first part 3310 may be inserted into the holder 1, or parts of both the first part 3310 and the second part 3320 may be inserted.

[0214] The user can inhale the aerosol with the second portion 3320 in their mouth. At this time, the aerosol is mixed with outside air and delivered to the user's mouth. As illustrated in Figure 21, outside air also flows in through at least one hole formed on the surface of the cigarette 3 (3110) and through at least one air passage formed in the holder 1 (3120). For example, the air passage formed in the holder 1 is also made to be opened and closed by the user.

[0215] Figures 22A and 22B are diagrams illustrating an example of a cigarette pack.

[0216] Referring to Figures 22A and 22B, the cigarette 3 includes a tobacco rod 3300, a first filter segment 3321, a cooling structure 3322, and a second filter segment 3323. The first part 3310, described with reference to Figure 21, includes the tobacco rod 3300, and the second part 3320 includes the first filter segment 3321, the cooling structure 3322, and the second filter segment 3323.

[0217] On the other hand, comparing Figure 22A and Figure 22B, the cigarette 3 in Figure 22B further includes a fourth trumpet 3334 compared to the cigarette 3 in Figure 22A.

[0218] However, the structure of the cigarette 3 shown in Figures 22A and 22B is merely an example, and some components may be omitted. For example, the cigarette 3 does not need to include one or more of the first filter segment 3321, the cooling structure 3322, and the second filter segment 3323.

[0219] The tobacco rod 3300 contains an aerosol-generating substance. For example, the aerosol-generating substance may contain 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 is about 7 mm to 15 mm, or preferably about 12 mm. The diameter of the tobacco rod 3300 is also 7 mm to 9 mm, or preferably about 7.9 mm. The length and diameter of the tobacco rod 3300 are not limited to the numerical ranges described above.

[0220] Furthermore, the tobacco rod 3300 may contain other additives such as flavoring agents, humectants, and / or acetate compounds. For example, the flavoring agents may include licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, mint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, salvia, spearmint, ginger, coriander, or coffee. The humectants may also include glycerin or propylene glycol.

[0221] As an example, the tobacco rod 3300 can also be filled with shredded tobacco. Here, the shredded tobacco can also be produced by finely crushing a tobacco sheet.

[0222] For a wide tobacco sheet to be filled into a narrow tobacco rod 3300, an additional process is required to ensure that the tobacco sheet can be easily folded. Therefore, filling the tobacco rod 3300 with shredded tobacco is even easier than filling it with tobacco sheets, and the productivity and efficiency of the tobacco rod 3300 production process are further increased.

[0223] As another example, the tobacco rod 3300 may also be filled with multiple tobacco strips, which are thin strips of tobacco sheet. For example, the tobacco rod 3300 may be formed by multiple tobacco strips aligned in the same direction (parallel) or randomly. A single tobacco strip may also be manufactured in the shape of a rectangular parallelepiped with a width of 1 mm, a length of 12 mm, and a thickness (height) of 0.1 mm, but is not limited to this.

[0224] Compared to a tobacco rod 3300 filled with tobacco sheets, a tobacco rod 3300 filled with tobacco fibers generates a larger amount of aerosol. Assuming they are filled in the same space, tobacco fibers guarantee a larger surface area than tobacco sheets. A larger surface area means that the aerosol-generating material has more opportunities to come into contact with the outside air. Therefore, when a tobacco rod 3300 is filled with tobacco fibers, more aerosol is generated compared to when it is filled with tobacco sheets.

[0225] Furthermore, when separating the cigarette 3 from the holder 1, the tobacco rod 3300 filled with tobacco fibers separates more easily than the tobacco rod 3300 filled with tobacco sheets. Compared to tobacco sheets, the frictional force generated by the tobacco fibers in contact with the heater 2130 is even smaller. Therefore, when the tobacco rod 3300 is filled with tobacco fibers, it separates more easily from the holder 1 than when it is filled with tobacco sheets.

[0226] The tobacco sheet can also be formed by grinding tobacco raw materials into a slurry and then drying the slurry. For example, 15 to 30% aerosol-generating material may be added to the slurry. The tobacco raw materials may also be tobacco leaf scraps, tobacco stems, tobacco dust generated during tobacco processing, and / or main side strips of tobacco leaves. The tobacco sheet may also contain other additives such as wood cellulose fiber.

[0227] The first filter segment 3321 is also a cellulose acetate filter. For example, the first filter segment 3321 can be a tube containing a cavity inside. The length of the first filter segment 3321 is approximately 7 mm to 15 mm, or preferably approximately 7 mm. The length of the first filter segment 3321 is shorter than approximately 7 mm, but it is desirable that it is long enough so as not to impair the function of at least one cigarette element (e.g., cooling element, capsule, acetate filter, etc.). The length of the first filter segment 3321 is not limited to the numerical range described above. On the other hand, the length of the first filter segment 3321 is expandable, and the overall length of the cigarette 3 is adjusted by the length of the first filter segment 3321.

[0228] The second filter segment 3323 is also a cellulose acetate filter. For example, the second filter segment 3323 may be made by a recess filter containing cavities, but is not limited to that. The length of the second filter segment 3323 may be approximately 5 mm to 15 mm, or preferably approximately 12 mm. The length of the second filter segment 3323 is not limited to the numerical ranges mentioned above.

[0229] Furthermore, the second filter segment 3323 may contain at least one capsule 3324. Here, the capsule 3324 is a structure in which a liquid containing fragrance is covered with a coating. For example, the capsule 3324 can have a spherical or cylindrical shape. The diameter of the capsule 3324 may be 2 mm or more, or preferably 2 to 4 mm.

[0230] The material forming the coating of capsule 3324 is also starch and / or a gelling agent. For example, gellan gum or gelatin can be used as a gelling agent. Furthermore, a gelling aid can be used as a material forming the coating of capsule 3324. Here, for example, calcium chloride can be used as the gelling aid. Furthermore, a plasticizer can be used as a material forming the coating of capsule 3324. Here, glycerin and / or sorbitol can be used as the plasticizer. Furthermore, a coloring agent can be used as a material forming the coating of capsule 3324.

[0231] For example, menthol and plant essential oils may be used as fragrances in the capsule's liquid contents. Furthermore, heavy-chain fatty acid triglycerides (heavy-chain) may be used as solvents for the fragrances in the liquid contents. The liquid contents may also contain other additives such as colorants, emulsifiers, and thickeners.

[0232] The cooling structure 3322 cools the aerosol generated by the heater 2130 heating the tobacco rod 3300. Thus, the user can inhale the aerosol cooled to a suitable temperature. The length of the cooling structure 3322 is approximately 10 mm to 20 mm, or preferably approximately 14 mm. The length of the cooling structure 3322 is not limited to the aforementioned numerical range.

[0233] For example, the cooling structure 3322 can also be made from polylactic acid. The cooling structure 3322 can also be made in various forms in order to increase the surface area per unit area (i.e., the surface area in contact with the aerosol). Various examples of the cooling structure 3322 will be described later with reference to Figures 23A to 23F.

[0234] The tobacco rod 3300 and the first filter segment 3321 are also packaged by a first flaps 3331. For example, the first flaps 3331 may be made of oil-resistant paper packaging material.

[0235] The cooling structure 3322 and the second filter segment 3323 are also packaged by the second wrapper 3332. The entire cigarette 3 is also repackaged by the third wrapper 3333. For example, the second wrapper 3332 and the third wrapper 3333 can also be made from common paper packaging materials. Optionally, the second wrapper 3332 may be oil-resistant hard wrapping paper or PLA scented paper. The second wrapper 3332 can also package the second filter segment 3323 portion and, in addition, further package the second filter segment 3323 and the cooling structure 3322.

[0236] Referring to Figure 22B, the cigarette 3 may include a fourth flap 3334. At least one of the tobacco rod 3300 and the first filter segment 3321 is also packaged by the fourth flap 3334. In other words, either only the tobacco rod 3300 is packaged by the fourth flap 3334, or both the tobacco rod 3300 and the first filter segment 3321 are packaged by the fourth flap 3334. For example, the fourth flap 3334 may also be made of paper packaging material.

[0237] The fourth flap 3334 is produced by applying (or coating) a predetermined substance to one or both surfaces of a paper packaging material. Here, an example of the predetermined substance is silicon, but it is not limited to silicon. Silicon possesses properties such as heat resistance with minimal temperature changes, oxidation resistance (no oxidation), resistance to various chemicals, water repellency, and electrical insulation. However, any substance possessing the aforementioned properties, even if not silicon, may be applied (or coated) to the fourth flap 3334 without limitation.

[0238] On the other hand, while Figure 22B illustrates cigarette 3 as including both the first horn 3331 and the fourth horn 3334, it is not limited to this. In other words, cigarette 3 may include only one of the first horn 3331 and the fourth horn 3334.

[0239] The fourth flap 3334 can prevent the cigarette 3 from burning. For example, if the tobacco rod 3300 is heated by the heater 2130, the cigarette 3 may burn. Specifically, if the temperature of any one of the substances contained in the tobacco rod 3300 rises above its ignition point, the cigarette 3 will burn. Even in such a case, the fourth flap 3334 contains a non-combustible material, thus preventing the cigarette 3 from burning.

[0240] Furthermore, the fourth flap 3334 can prevent the holder 1 from being contaminated by substances generated in the cigarette 3. The user's puffing can also generate liquid substances within the cigarette 3. For example, the aerosol generated in the cigarette 3 is cooled by the outside air, generating liquid substances (e.g., water). The fourth flap 3334, by enclosing the tobacco rod 3300 and / or the first filter segment 3321, prevents the liquid substances generated in the cigarette 3 from leaking outside the cigarette 3. Therefore, the holder 1 case 2140 and other parts are prevented from being contaminated by the liquid substances generated in the cigarette 3.

[0241] Figures 23A to 23F are diagrams illustrating examples of cigarette cooling structures.

[0242] For example, the cooling structures shown in Figures 23A to 23F can also be fabricated using fibers produced from pure polylactic acid (PLA).

[0243] For example, when a film (sheet) is used to create a cooling structure, the film (sheet) may tear due to external impact. In that case, the cooling effect of the cooling structure on aerosols is reduced.

[0244] As another example, when manufacturing cooling structures by extrusion molding or similar methods, the process becomes less efficient due to the addition of steps such as cutting the structure. Furthermore, there are limitations to manufacturing these cooling structures in a variety of shapes.

[0245] By fabricating a cooling structure according to one embodiment using polylactic acid fiber (for example, by weaving), the risk of the cooling structure being deformed or losing its function due to external impact is reduced. Furthermore, by changing the method of combining the fibers, cooling structures with a variety of shapes can be fabricated.

[0246] Furthermore, by using fibers to fabricate the cooling structure, the surface area in contact with the aerosol is increased. Consequently, the aerosol cooling effect of the cooling structure is further improved.

[0247] Referring to Figure 23A, the cooling structure 3510 can also be manufactured in a cylindrical shape, and at least one air passage 3511 can be formed in the cross-section of the cooling structure 3510.

[0248] Referring to Figure 23B, the cooling structure 3520 can also be made from a structure in which multiple fibers are woven together. In this case, the aerosol flows between the fibers, and a vortex is formed depending on the shape of the cooling structure 3520. The formed vortex increases the surface area in contact with the aerosol within the cooling structure 3520, extending the time that the aerosol remains within the cooling structure 3520. Therefore, the heated aerosol is effectively cooled.

[0249] Referring to Figure 23C, the cooling structure 3530 can also be manufactured in a form in which multiple bundles 3531 are assembled together.

[0250] Referring to Figure 23D, the cooling structure 3540 is also filled with granules made from polylactic acid, shredded tobacco, or charcoal, respectively. The granules may also be made from a mixture of polylactic acid, shredded tobacco, and charcoal. On the other hand, the granules may further contain elements other than polylactic acid, shredded tobacco, and / or charcoal that can improve the cooling effect of the aerosol.

[0251] Referring to Figure 23E, the cooling structure 3550 may include a first section 3551 and a second section 3552.

[0252] The first cross section 3551 is adjacent to the first filter segment 3321 and contains a void into which aerosols flow. The second cross section 3552 is adjacent to the second filter segment 3323 and may contain a void from which aerosols are released. For example, the first cross section 3551 and the second cross section 3552 may contain a single void with the same diameter, but the diameter and number of voids contained in the first cross section 3551 and the second cross section 3552 are not limited thereto.

[0253] In addition, the cooling structure 3550 may include a third section 3553 between the first section 3551 and the second section 3552, which contains a plurality of voids. For example, the diameters of the voids contained in the third section 3553 are smaller than the diameters of the voids contained in the first section 3551 and the second section 3552. Also, the number of voids contained in the third section 3553 is greater than the number of voids contained in the first section 3551 and the second section 3552.

[0254] Referring to Figure 23F, the cooling structure 3560 may include a first cross section 3561 adjacent to the first filter segment 3321, and a second cross section 3562 adjacent to the second filter segment 3323. The cooling structure 3560 may also include one or more tubular elements 3563. For example, a tubular element 3563 can penetrate the first cross section 3561 and the second cross section 3562. The tubular element 3563 may also be packaged with a microporous packaging material and filled with a filler (for example, granules as described with reference to Figure 23D) that can improve the cooling effect of the aerosol.

[0255] As described above, the holder can generate an aerosol by heating the cigarette. Furthermore, the holder can generate an aerosol independently or when it is inserted into the cradle and tilted. In particular, when the holder is tilted, the heater is heated by the cradle's battery power.
