[0002] The present invention relates to an aerosol generating device, in particular to providing various feedbacks by recognizing a user's puffs. Background Art

[0003] Existing smoking products generate aerosols by directly combusting aerosol-generating substances during use. However, direct combustion of aerosol-generating substances can produce undesirable volatile compounds, potentially leading to health concerns. Consequently, various aerosol-generating devices have recently been developed that heat aerosol-generating substances without combustion, thereby preventing the generation of undesirable volatile compounds while still providing a pleasant cigarette flavor.

[0004] However, compared to existing combustible cigarettes, aerosol-generating devices may not provide users with sufficient satisfaction. For example, the sensation provided by aerosol-generating devices is different from that of existing combustible cigarettes, and the number of puffs and the amount of aerosol generated by aerosol-generating devices are also different from those of existing combustible cigarettes.

[0005] Therefore, there is a need to provide a method that allows a user to use an aerosol generating device to obtain a sensation that is as similar as possible to the sensation of smoking a cigarette. Summary of the Invention

[0042] In some embodiments for solving the problems of the prior art as described above, the holder includes: a battery for powering; a heater for heating the aerosol-generating substance; a sensor; at least one output unit; and a control unit, wherein the control unit uses the sensor to detect the user's puffing and can control the at least one output unit based on puff characteristic data corresponding to the detection result.

[0043] The terms used in this invention are selected from commonly used terms, taking into account the purpose of the invention. However, the terms may be changed based on the intentions of those skilled in the art, precedents, or the emergence of new technologies in the field. In addition, in specific cases, the applicant may arbitrarily select certain terms, and in such cases, the meaning of the selected terms will be described in detail in the explanatory section of this specification. Therefore, the terms used in this invention should be defined based on their meaning and the content of the entire specification, rather than simply by their names.

[0044] Throughout this specification, when a part is described as being connected to another part, this includes both direct connections and electrical connections via other components. When a part "includes" a certain component, unless otherwise specifically described, it indicates that the part may also include other components, not exclude other components. Furthermore, terms such as "unit" and "module" described in this specification refer to units that perform at least one function or action, and may be implemented in hardware or software, or as a combination of hardware and software.

[0045] Throughout this specification, an aerosol-forming substance refers to a substance that is capable of generating an aerosol and may refer to an aerosol-forming substrate. An aerosol may contain volatile compounds. An aerosol-forming substance may be a solid or a liquid.

[0046] For example, solid aerosol-forming substances may include solid substances based on tobacco raw materials such as leaf tobacco, tobacco leaves, and reconstituted tobacco, while liquid aerosol-forming substances may include liquid substances based on nicotine, tobacco extracts, and various flavoring agents. Of course, the above examples are not limiting.

[0047] Throughout this specification, an aerosol-generating device (hereinafter referred to as a "holder") may be a device that generates an aerosol using an aerosol-generating substance in order 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" may be used interchangeably.

[0048] Throughout the specification, inhalation refers to inhalation by the user, and inhalation refers to a state in which liquid is inhaled into the oral cavity, nasal cavity or lungs of the user through the mouth and nose of the user.

[0049] Throughout this specification, puff characteristics data may include information related to puff intensity, puff interval, and puff count. For example, information related to the user's puff intensity, the time interval between puffs, the number of puffs remaining, and the current total number of puffs may be included, without limitation to the examples above.

[0050] Figure 1 Shows the appearance of a retainer according to some embodiments.

[0051] according to Figure 1 In the example shown, the holder 1 may be in the shape of a bar. Like conventional cigarettes, the user can hold the holder 1 between their fingers for use. Alternatively, the holder 1 may be in the shape of a holder. That is, the solid aerosol-generating substance 3 is inserted into the holder 1 and heated, thereby generating an aerosol. According to some embodiments, the solid aerosol-generating substance 3 may be a cigarette. The terms "cigarette" and "aerosol-generating substance 3" may be used interchangeably. Below, the action performed when the aerosol-generating substance 3 is inserted into the holder 1 and the structure of the cigarette are described in more detail.

[0052] According to some embodiments, after the aerosol is generated, the generated aerosol can be delivered to the user through a filter. The filter can be set on the holder 1 or attached to the aerosol generating material 3, but is not limited to the above examples.

[0053] In addition, 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 light 122, but the examples are not limited thereto. The at least one output unit included in the holder 1 is described in more detail below.

[0054] Additionally, according to some embodiments, the holder 1 can be powered on or off by a user's input, or can be powered on when a user's puff is detected. Figure 2 is described in .

[0055] In addition, according to some embodiments, the retainer 1 can be combined with a bracket. The details of the bracket are described in detail in the following figures.

[0056] Figure 2 A block diagram showing a retainer 1 according to some embodiments.

[0057] Figure 2 The holder 1 shown may include a battery 110, a control unit 120, a sensor 130, an output unit 140, and a heater 150. However, Figure 2 The components shown are not all necessary components of the retainer 1. Figure 2The components shown are as follows; the holder 1 may be implemented by more components or by fewer components.

[0058] According to some embodiments, the control unit 120 controls the overall operation of the holder 1. The control unit 120 may include a microprocessor, a microcontroller, and an IC circuit including these, but is not limited to the above examples.

[0059] According to some embodiments, the control unit 120 may use the sensor 130 to detect the user's puffing. In addition, the control unit 120 may obtain puffing characteristic data based on the puffing detection result. The control unit 120 may control the output unit 140 based on the puffing characteristic data.

[0060] According to some embodiments, the holder 1 may include an output unit 140. The output unit 140 may include, but is not limited to, displays such as an LED display window, an LED light, a motor, a speaker, a temperature controller, and the like. Furthermore, the holder 1 may include at least one output unit 140. For example, a single holder 1 may include an LED display window, an LED light, and a motor.

[0061] According to some embodiments, the control unit 120 may control the output unit 140 according to the puffing characteristic data.

[0062] For example, the control unit 120 can predict the number of puffs remaining and, by recognizing the user's puffs, output the number of puffs obtained by subtracting the user's puffs from the remaining number of puffs. In other words, the control unit 120 can output the changed number of puffs remaining. The control unit 120 can predict the number of puffs remaining based on the battery level and the amount of aerosol-generating substances (e.g., cigarettes).

[0063] Additionally, according to some embodiments, the control unit 120 may control the output intensity of the vibration motor based on the number of puffs remaining. For example, the control unit 120 may control the vibration motor so that the output increases as the number of puffs remaining decreases. Of course, the opposite control may also be employed, where the control unit 120 may control the vibration motor so that the number of vibrations equals the number of puffs remaining.

[0064] Furthermore, the control unit 120 may control the LED light's illumination intensity or blinking interval based on the number of puffs remaining. For example, the control unit 120 may control the LED light so that the output of the LED light increases as the number of puffs remaining decreases. Of course, the opposite control may also be employed, where the control unit 120 may control the LED light so that the blinking speed increases as the number of puffs remaining decreases.

[0065] Furthermore, the control unit 120 may control the intensity or type of sound effect output based on the number of puffs remaining. For example, the control unit 120 may control the sound effect output unit 140, such as a speaker, to output a louder sound effect as the number of puffs remaining decreases. Furthermore, the control unit 120 may control the sound effect output unit 140 to output one of a variety of sound effects, such as wind sounds or burning paper.

[0066] Furthermore, the control unit 120 can control the temperature of the housing 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 of the holder may not notice the high temperature. Therefore, when the temperature of the heater 150 is too high, the external housing temperature can be raised to a predetermined temperature or higher. This allows the user to be informed of the temperature of the heater 150 through the change in housing temperature.

[0067] Furthermore, the control unit 120 may provide a prompt 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 satisfies the user (e.g., based on the size of the generated aerosol particles, the amount of generated aerosol, the temperature of the generated aerosol, etc.). Therefore, the control unit 120 may control the output unit 140 to prompt the user each time the temperature of the heater 150 is heated to a predetermined temperature or higher, so that the user can inhale the optimal aerosol.

[0068] In addition, the control unit 120 can control the output unit 140 to remind the user to take an inhalation at a predetermined interval. In other words, in order to provide the best aerosol, the control unit 120 can remind the user at a predetermined time interval.

[0069] In addition, according to some embodiments, the control unit 120 may control the output unit 140 to prompt the user based on the measured puff intensity or the measured puff interval. Because excessively strong puffs or puffs with too short intervals cannot provide a satisfactory aerosol, the control unit 120 may control the output unit 140 to prompt the user when the user puffs too strongly or the intervals between puffs are too short, so that the user can puff according to the specified puff intensity and puff interval based on the specified standards.

[0070] The sensor 130 may be a variety of sensors and may include at least one sensor. For example, the sensor 130 may include a flow sensor and a temperature sensor.

[0071] According to some embodiments, the controller 120 may use a temperature sensor to measure the temperature of the heater 150. The temperature sensor may be a sensor that measures the temperature of the air surrounding the heater, or a sensor that uses the heater's conductive tracks to determine the heater's temperature. By measuring the temperature of the heater 150, the controller 120 can detect the user's puffs.

[0072] According to some embodiments, the control unit 120 can use a flow sensor to measure the direction and / or flow rate of air, gas, or aerosol within the holder. The control unit 120 can detect the user's puffing by measuring changes in the flow rate. The general structure of the control unit 120 is described in more detail in the following figures.

[0073] According to some embodiments, the heater 150 can heat an aerosol-generating substance (e.g., a cigarette or liquid) using electricity supplied by the battery 110. The temperature of the heater 150 can be set differently depending on the type of aerosol-generating substance. Specifically, the temperature of the heater 150 can vary depending on whether the aerosol-generating substance is solid or liquid. If the aerosol-generating substance is solid, the temperature can vary depending on the thickness and structural material of the aerosol-generating substance. A detailed description of the battery 110 is provided below.

[0074] Furthermore, heater 150 can have various shapes. It can be a tubular heater, a plate heater, or a needle or rod heater. Depending on its shape, heater 150 heats the inside or outside of the aerosol-forming substance. The structure of heater 150 is described in more detail below.

[0075] According to some embodiments, the controller 120 can control the heater 150 and the battery 110. Specifically, the controller 120 can preheat the heater 150 to a specified temperature and control the battery 110 to conserve energy. Furthermore, the controller 120 can utilize stored profiles to control the battery 110 and heater 150 in various modes.

[0076] For example, the control unit 120 may perform control in energy saving mode or preheating mode, normal inhalation mode, or amplified inhalation mode that generates more aerosol at a higher temperature than the normal inhalation mode but uses more power, but is not limited to the above examples.

[0077] According to some embodiments, battery 110 may include at least one power source. For example, battery 110 may include at least one battery. Battery 110 may be charged via an external charging device, with no particular limitation on the charging method. Furthermore, when battery 110 is fully charged, the power supply of the holder may be automatically disconnected or the holder may operate in a power-saving mode.

[0078] Additionally, the holder 1 may include a memory (not shown), in which user information, configuration files and other data for temperature control, as well as puffing performance data, etc. may be stored.

[0079] Figure 3 and Figure 4 A conceptual diagram showing a retainer according to some embodiments.

[0080] Reference Figure 3 The holder 1 may include an outer shell 170. The outer shell may include a battery 110, a control unit 120, a sensor 130, an output unit 140, and a heater 150. In addition, the solid aerosol generating material 3 may be inserted from the outside of the holder 1. The actions of each structure correspond to Figure 2 Therefore, detailed description is omitted.

[0081] Compared to Figure 3 , Figure 4 In the embodiment, the holder 1 further comprises a liquid storage portion 180. The liquid storage portion 180 comprises a liquid aerosol-generating substance. Figure 4 The holder 1 can heat the solid aerosol-forming substance and the liquid aerosol-forming substance simultaneously, alternately, and / or sequentially, thereby being able to generate the aerosol-forming substance.

[0082] in addition, Figure 4 The holder 1 can heat the liquid aerosol-forming material by a separate heater, and is not limited to the heater structure that heats liquid aerosol-forming material and solid aerosol-forming material. The following figures further illustrate and explain the concept diagram of the holder.

[0083] Figure 5 A control method for a holder that detects suction to control an output portion according to some embodiments is shown.

[0084] In step 501, the holder may detect the user's puffing using a sensor. The holder may detect the user's puffing using a flow sensor or a temperature sensor.

[0085] According to some embodiments, the holder is capable of detecting a user's puff by utilizing a flow sensor to determine the amount of air flowing into or out of the holder.

[0086] The holder can also detect the user's puffs by measuring the heater's temperature using a temperature sensor and identifying changes in the heater's temperature. Furthermore, the holder can use a pressure sensor to identify the user's puffs. The methods by which the holder can detect the user's puffs are not limited to the examples above.

[0087] In step 503 , the holder may obtain suction characteristic data according to the detection result.

[0088] According to some embodiments, the puff characteristics data may include information related to puff intensity, puff interval, and number of puffs. Specifically, the puff characteristics data may include information related to the user's puff pressure (puff intensity, strength), the time interval between the first and second puffs, the remaining number of puffs, and the current total number of puffs. The current total number of puffs may refer to the number of puffs calculated after the holder is opened or after the aerosol-generating material is inserted, but is not limited to the above examples.

[0089] According to some embodiments, the holder can detect at least one puff taken by the user to obtain information related to the puff intensity, puff interval, puff number, etc.

[0090] In step 505 , the holder may control at least one output portion according to the suction characteristic data.

[0091] According to some embodiments, the holder can control the output unit according to the number of puffs remaining. For example, the holder can control the vibration motor to vibrate weakly when the number of puffs remaining is greater than a predetermined number, and vibrate strongly when the number of puffs remaining is less than the predetermined number.

[0092] Further, the holder may control the LED light to have a shorter blinking interval as the number of puffs remaining decreases, or to increase the light emission intensity as the number of puffs remaining decreases.

[0093] In addition, according to some embodiments, the holder can control the output part according to the suction intensity. For example, the holder can be controlled in a manner that the suction intensity is proportional to the vibration intensity of the vibration motor. The method of the holder controlling at least one output part according to the suction characteristic data is not limited to this, and may also include Figure 2 The contents described in .

[0094] Figure 6 The following describes an output mode control method based on the remaining number of puffs according to some embodiments.

[0095] In step 601, the holder may utilize a sensor to detect the user's inhalation. This corresponds to the content described above, so detailed description is omitted.

[0096] In step 603, the holder may determine whether the remaining number of puffs is below a critical value.

[0097] According to some embodiments, the holder can predict the remaining number of puffs. The holder can predict the remaining number of puffs based on the quality of the aerosol generated, the battery level, the standard puff strength, the number of puffs taken by the user, etc.

[0098] Furthermore, the number of puffs remaining can change based on the user's puff intensity and puff interval. For example, if the holder initially predicts a remaining number of puffs of 8 based on the aerosol-forming substance and battery level, after the user takes two puffs, the number of puffs remaining may be predicted to be 5 instead of 6, depending on the user's puff intensity and puff interval. In other words, the holder can calculate the remaining number of puffs based on puff characteristic data.

[0099] According to some embodiments, the holder can determine whether the calculated number of puffs remaining is above or below a threshold value. Furthermore, the holder can output the calculated number of puffs remaining. In the holder, the output can be via an LED display window or an LED light.

[0100] In step 605, the retainer can maintain the output mode when the remaining number of puffs is greater than a critical value. The output mode refers to the mode in which the retainer controls at least one output unit.

[0101] For example, the first stage of the output mode may refer to the first stage lighting mode of the LED lamp and the first stage vibration mode of the vibration motor, and the second stage of the output mode may refer to the second stage lighting mode of the LED lamp and the second stage vibration mode of the vibration motor, but is not limited to the above examples.

[0102] In other words, an output mode may refer to a combination of output modes of at least one output unit included in the holder. Specifically, an LED light's light pattern may refer to a predetermined LED flashing intensity and flashing interval, and a vibration motor's vibration mode may refer to a predetermined vibration intensity and vibration interval, but the examples are not limited thereto.

[0103] According to some embodiments, the retainer can maintain the output mode when the number of puffs remaining is above a threshold. That is, the retainer may not change the output mode. For example, the retainer can maintain the output mode in the first stage when the number of puffs remaining is four or more.

[0104] In step 607, when the number of puffs remaining is below the threshold, the holder may determine whether the number of puffs remaining is 0. For example, when it is determined that the number of puffs remaining is 4 or less, the holder may confirm whether the number of puffs remaining is 0.

[0105] In step 609, the retainer may change the output mode when the remaining number of puffs is not 0. For example, the retainer may change the output mode to the second stage when the remaining number of puffs is not 0 and is less than 4.

[0106] In addition, in step 611, when the remaining number of puffs is 0, the holder can stop the output mode. That is, the holder can stop the flashing of the LED and the vibration of the vibration motor.

[0107] Of course, the holder does not completely stop the output mode; rather, the output mode can be changed, and an output unit different from that used in the existing output mode can be used to indicate the need to remove or replace the aerosol-generating material or to recharge the device. For example, when the number of puffs remaining in the holder reaches 0, instead of using the LED light and vibration motor, the holder can use an LED display window to notify the user that the aerosol-generating material needs to be removed or replaced, or that the holder needs to be recharged.

[0108] Figure 7 Shows the change in heater temperature based on puffing for some embodiments.

[0109] As previously explained, the action of the user inhaling the generated aerosol through the holder may be referred to as puffing.

[0110] According to some embodiments, during inhalation, the holder not only transmits aerosol generated by the aerosol-generating substance through heating to the user, but also transmits the generated aerosol to the user through the air flowing out through the holder and mixing with the aerosol.

[0111] According to some embodiments, the holder can detect the user's puffing through various methods. For example, the holder can utilize a pressure sensor to measure pressure changes within the holder, thereby detecting the user's puffing. However, even if the holder does not have a separate pressure sensor, it can still detect the user's puffing by measuring the temperature of the heater.

[0112] The heater temperature may vary with each puff. When a puff is taken, the heater temperature drops as air cooler than the heater temperature flows from the holder. Figure 7 , it can be seen that when the user first inhales the first puff 701 of the aerosol, the temperature of the heater drops.

[0113] The holder then supplies power to the heater, raising the heater temperature back to the specified temperature. Similar to the first puff 701, the heater temperature drops during the second and third puffs 702 and 703. The holder can detect the occurrence of a puff by measuring the heater temperature; a drop in the heater temperature indicates the occurrence of a puff. Furthermore, since the heater temperature drops during a puff, the holder can supply power to raise the heater temperature back to the specified temperature.

[0114] Figure 8 Shown are changes in flow rate based on suction for some embodiments.

[0115] As previously mentioned, during a puff, not only is the aerosol generated by the aerosol-generating substance through the heating of the holder delivered to the user, but air flowing through the holder to the outside mixes with the generated aerosol and is delivered to the user. Therefore, the holder can detect the user's puff based on changes in the flow rate within the holder.

[0116] The flow rate may vary with each puff taken by the user. When puffing, air flows into the holder from outside, so the flow rate inside the holder increases. Figure 8 , it can be seen that the flow rate increases when the user first inhales the aerosol in the first puff 801 .

[0117] Similar to the first puff 801, the flow rate increases during the second and third puffs 802 and 803. The retainer can detect the occurrence of puffing by measuring changes in the flow rate; an increase in flow rate indicates the occurrence of puffing. Therefore, even without a separate pressure sensor, the retainer can detect puffing based on changes in flow rate and temperature. Furthermore, the retainer can detect the intensity of puffing based on the degree of change in flow rate and temperature.

[0118] Figures 9a to 9c This section illustrates some embodiments of controlling LED light output based on the number of puffs remaining.

[0119] As described above, the holder 1 can change the output mode according to the remaining number of possible puffs.

[0120] like Figures 9a to 9c As shown, when the remaining number of puffs is 5, 3, and 1, the holder 1 can control the flashing color, flashing degree, and flashing interval of the LED light 901 to be different. Figures 9a to 9c The LED lamp 901 can be with Figure 1 The same light as the LED light 122. In addition, when the remaining number of puffs is 0, the holder 1 can control the LED light not to flash.

[0121] Additionally, the holder 1 can be controlled so that the LED light 901 flashes only during suction. In addition, the holder 1 can control the flashing intensity of the LED light 901 and output sound effects in order to interact with the user's input using the power button or input button.

[0122] In addition, the holder 1 can also control an LED light or a vibration motor to prompt the user to insert or discharge the aerosol-generating material. In other words, the at least one output unit included in the holder 1 can be controlled to interact with the user, provide feedback on the user's puffing, or provide prompts to the user.

[0123] Figure 10 The relationship between the suction intensity and the vibration intensity of some embodiments is shown.

[0124] According to some embodiments, the user's suction intensity may be proportional to the vibration intensity of the vibration motor in the holder. That is, the vibration intensity may also vary according to the user's suction intensity.

[0125] like Figure 10 As shown, when the vibration intensity is adjusted according to the user's puff intensity, the user can immediately provide feedback on the puff intensity. To provide the best aerosol, it is necessary to puff with an appropriate intensity. The holder provides feedback on the puff intensity to the user through the vibration intensity, thereby guiding the user to puff at an appropriate intensity.

[0126] Of course, with Figure 10 On the contrary, the stronger the suction intensity, the weaker the vibration intensity. The relationship between vibration intensity and suction intensity is not limited. In other words, as long as feedback can be given to the user.

[0127] Figure 11 This is a structural diagram showing an example of an aerosol generating device.

[0128] Reference Figure 11 The aerosol generating device 1 (hereinafter referred to as "holder") includes a battery 110, a control unit 120, and a heater 2130. The holder 1 also includes an internal space formed by a housing 2140. A cigarette can be inserted into the internal space of the holder 1. Figure 11 The holder 1 shown may be an embodiment different from the holder 1 described previously, or may correspond in part or in whole to the structure of the holder 1 described previously.

[0129] Figure 11 The holder 1 shown only shows the components related to this embodiment. Therefore, a person skilled in the art of the present embodiment should understand that the holder 1 may also include Figure 11 Common parts other than those shown.

[0130] When a cigarette is inserted into holder 1, holder 1 heats heater 2130. Heat from heater 2130 raises the temperature of the aerosol-generating substances within the cigarette, generating aerosol. This generated aerosol is then transferred to the user through the cigarette filter. However, holder 1 can also heat heater 2130 even when a cigarette is not inserted.

[0131] The housing 2140 can be separated from the holder 1. For example, the user can separate the housing 2140 from the holder 1 by rotating the housing 2140 clockwise or counterclockwise.

[0132] Furthermore, the diameter of the hole formed by the distal end 2141 of the housing 2140 may be made smaller than the diameter of the space formed by the housing 2140 and the heater 2130 . In this case, the hole can guide the cigarette inserted into the holder 1 .

[0133] The battery 110 supplies power for operating the holder 1. For example, the battery 110 can supply power to heat the heater 2130 and can also supply power required for operating the control unit 120. Furthermore, the battery 110 can supply power required for operating the display, sensors, motors, and other output components provided in the holder 1.

[0134] The battery 110 may be a lithium iron phosphate (LiFePO 4 ) battery, but is not limited to the above example. For example, the battery 110 may be a lithium cobalt oxide (LiCoO 2 ) battery, a lithium titanate battery, or the like.

[0135] Furthermore, battery 110 may be cylindrical with a diameter of 10 mm and a length of 37 mm, but is not limited thereto. Battery 110 may have a capacity of 120 mAh or greater and may be a rechargeable or disposable battery. For example, if battery 110 is a rechargeable battery, the charge rate (C-rate) of battery 110 may be 10C, and the discharge rate (C-rate) may be 16C to 20C, but is not limited thereto. Furthermore, for stable use, battery 110 may be manufactured to maintain at least 80% of its total capacity even after 8,000 charge / discharge cycles.

[0136] Here, whether battery 110 is fully charged or fully discharged can be determined based on the level of power stored in battery 110 relative to the total capacity of battery 110. For example, if the power stored in battery 110 is 95% or more of the total capacity, battery 110 can be determined to be fully charged. Alternatively, if the power stored in battery 110 is 10% or less of the total capacity, battery 110 can be determined to be fully discharged. However, the criteria for determining whether battery 110 is fully charged or fully discharged are not limited to the above examples.

[0137] Heater 2130 is heated by power supplied by battery 110. When a cigarette is inserted into holder 1, heater 2130 is located inside the cigarette. Therefore, heater 2130 heats the cigarette, raising the temperature of the aerosol-forming substances within the cigarette. Heater 2130 may have a structure similar to heater 150 described above.

[0138] Heater 2130 can have a combined cylindrical and conical shape. For example, heater 2130 can have a cylindrical shape with a diameter of approximately 2 mm and a length of approximately 23 mm. The distal end 2131 of heater 2130 can terminate at an acute angle, but this is not limiting. In other words, any shape of heater 2130 is acceptable as long as it can be inserted into a cigarette. Furthermore, heater 2130 can be heated only partially. For example, assuming heater 2130 is 23 mm long, only the portion from distal end 2131 to 12 mm can be heated, leaving the remaining portion unheated.

[0139] The heater 2130 may be a resistive heater. For example, the heater 2130 may include a conductive track, and the heater 2130 may be heated as current flows through the conductive track.

[0140] For stable operation, heater 2130 may be supplied with power at, but is not limited to, 3.2V, 2.4A, and 8W. For example, when power is supplied to heater 2130, the surface temperature of heater 2130 may rise to over 400°C. Within 15 seconds of powering heater 2130, the surface temperature of heater 2130 may rise to approximately 350°C.

[0141] The holder 1 may be equipped with a separate temperature sensor. Alternatively, the holder 1 may not be equipped with a temperature sensor, but the heater 2130 may function as the temperature sensor. For example, the heater 2130 may include a second conductive track for temperature detection in addition to a first conductive track for heat generation.

[0142] For example, if the voltage across the second conductive track and the current flowing through the second conductive track are measured, the resistance R can be determined. In this case, the temperature T of the second conductive track can be determined by the following equation 1. The temperature detection sensor can be an embodiment of the sensor 130 described above.

[0143] Mathematical formula 1

[0144] R=R0{1+α(T-T0)}

[0145] In Mathematical Formula 1, R represents the current resistance value of the second conductive track, R0 represents the resistance value 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 inherent temperature coefficients of resistance, so α is predetermined based on the conductive material used to construct the second conductive track. Therefore, if the resistance R of the second conductive track is known, the temperature T of the second conductive track can be calculated using Mathematical Formula 1.

[0146] The heater 2130 may be composed of at least one conductive track (a first conductive track and a second conductive track). For example, the heater 2130 may be composed of two first conductive tracks and one or two second conductive tracks, but is not limited thereto.

[0147] The conductive track comprises a resistive material. As one example, the conductive track is made of a metal material. As another example, the conductive track can be made of a conductive ceramic material, carbon, a metal alloy, or a composite material of a ceramic material and a metal.

[0148] In addition, the holder 1 may include both the conductive rail functioning as a temperature detection sensor and the temperature detection sensor.

[0149] The control unit 120 controls the overall operation of the holder 1. Specifically, the control unit 120 controls the operation of the battery 110 and the heater 2130, as well as the operation of other components in the holder 1. Furthermore, the control unit 120 can determine whether the holder 1 is ready for operation by checking the status of each component of the holder 1.

[0150] The control unit 120 includes at least one processor. The processor can be implemented as a plurality of logic gate arrays or as a combination of a general-purpose microprocessor and a memory storing a program executable by the microprocessor. Furthermore, those skilled in the art will appreciate that the processor can also be implemented as a hard disk in other forms.

[0151] 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 the power supply so that the heater 2130 can be heated to a predetermined temperature or maintained at an appropriate temperature. In addition, the control unit 120 can check the status of the battery 110 (e.g., the remaining battery charge) and generate a warning signal when necessary.

[0152] Furthermore, the control unit 120 can confirm whether the user has puffed and the intensity of the puff, and can count the number of puffs. Furthermore, the control unit 120 can continuously confirm the operating time of the holder 1. Furthermore, the control unit 120 can confirm whether the bracket 2 described below is engaged with the holder 1 and control the movement of the holder 1 based on whether the bracket 2 is engaged or disengaged with the holder 1.

[0153] On the one hand, the holder 1 may include a common structure in addition to the battery 110 , the control unit 120 and the heater 2130 .

[0154] For example, the holder 1 may include a display capable of outputting visual information or a motor for outputting tactile information. For example, when the holder 1 includes a display, the control unit 120 may transmit information about the status of the holder 1 (e.g., whether the holder can be used), information about the heater 2130 (e.g., preheating started, preheating in progress, preheating completed, etc.), information about the battery 110 (e.g., remaining battery capacity, whether it can be used, etc.), information about resetting the holder 1 (e.g., reset timing, resetting in progress, reset completed, etc.), information about cleaning the holder 1 (e.g., cleaning timing, cleaning required, cleaning in progress, cleaning completed, etc.), information about charging the holder 1 (e.g., charging required, charging in progress, charging completed, etc.), information about puffing (e.g., number of puffs, puff end notification, etc.), or safety-related information (e.g., usage time elapsed, etc.). For another example, when the holder 1 includes a motor, the control unit 120 may use the motor to generate a vibration signal to transmit the above information to the user.

[0155] In addition, the holder 1 may include at least one input device (e.g., a button) and / or a terminal coupled to the bracket 2, through which the user can control the holder 1. For example, the user can utilize the input device of the 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 of the press (e.g., 0.1 seconds, 0.2 seconds, etc.), the desired function among the multiple functions of the holder 1 can be executed. As the user activates the input device, the holder 1 can perform functions such as preheating the heater 2130, adjusting the temperature of the heater 2130, cleaning the space for inserting a cigarette, checking whether the holder 1 is in an operable state, displaying the remaining amount of the battery 110 (available power), resetting the holder 1, and the like. However, the functions of the holder 1 are not limited to the above examples.

[0156] In addition, the 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 be implemented as a common pressure sensor, and the cigarette insertion detection sensor may be implemented as a common capacitance sensor or resistance sensor. Furthermore, the holder 1 may be constructed to allow for the inflow and outflow of external air even when a cigarette is inserted.

[0157] Figure 12a and Figure 12b These are views showing an example of a cage from multiple side surfaces.

[0158] Figure 12a 1 is a diagram showing an example of viewing the retainer 1 from the first direction. Figure 12aAs shown, the holder 1 can be manufactured in a cylindrical shape, but is not limited thereto. The housing 2140 of the holder 1 can be separated by a user's action, and a cigarette can be inserted from the end 2141 of the housing 2140. In addition, the holder 1 can have buttons 2150 for the user to control the holder 1 and a display 2160 for outputting images. The housing 2140 can be an embodiment of the housing described above.

[0159] Figure 12b 2 is a diagram showing an example of observing the holder 1 from the second direction. The holder 1 may include a terminal 2170 coupled to the bracket 2. The terminal 2170 of the holder 1 is coupled to the terminal 2260 of the bracket 2, so that the battery 110 of the holder 1 can be charged by the power supplied by the battery 210 of the bracket 2. In addition, through the terminal 2170 and the terminal 2260, the holder 1 can be operated based on the power supplied by the battery 210 of the bracket 2, and communication (signal transmission / reception) between the holder 1 and the bracket 2 can also be achieved. For example, the terminal 2170 may include four micro needles (pins), but is not limited to this.

[0160] Figure 13 This is a structural diagram showing an example of a bracket.

[0161] Reference Figure 13 The bracket 2 includes a battery 210 and a control unit 220. Furthermore, the bracket 2 has an internal space 2230 for inserting the holder 1. For example, the internal space 2230 may be formed on a side surface of the bracket 2. Therefore, even if the bracket 2 does not have a separate cover, the holder 1 can be inserted and fixed in the bracket 2.

[0162] Figure 13 The bracket 2 shown only shows the components related to this embodiment. Therefore, a person skilled in the art of the present embodiment should understand that, except for Figure 13 In addition to the components shown, the bracket 2 may also include common components.

[0163] The battery 210 supplies power for operating the cradle 2. Furthermore, the battery 210 can supply power for charging the battery 110 of the holder 1. For example, when the holder 1 is inserted into the cradle 2 and the terminals 2170 of the holder 1 are engaged with the terminals 2260 of the cradle 2, the battery 210 of the cradle 2 can supply power to the battery 110 of the holder 1.

[0164] Furthermore, when the holder 1 is coupled to the bracket 2, the battery 210 can supply the power required for the operation of the holder 1. For example, when the terminal 2170 of the holder 1 is coupled to the terminal 2260 of the bracket 2, the holder 1 can operate using the power supplied by the battery 210 of the bracket 2, regardless of whether the battery 110 of the holder 1 is discharged.

[0165] Examples of battery 210 types can be found in Figure 11 The above-mentioned example of battery 110 is the same. The capacity of battery 210 may be greater than that of battery 110, for example, the capacity of battery 210 may be greater than 3000 mAh, but the capacity of battery 210 is not limited to the above example.

[0166] The control unit 220 controls the overall movement of the bracket 2. The control unit 220 can control the movement of all components of the bracket 2. In addition, the control unit 220 determines whether the holder 1 is engaged with the bracket 2 and can control the movement of the bracket 2 based on whether the bracket 2 is engaged or separated from the holder 1.

[0167] For example, when the holder 1 is coupled to the cradle 2, the control unit 220 supplies power from the battery 210 to the holder 1, thereby charging the battery 110 or heating the heater 2130. Therefore, even when the remaining power of the battery 110 is low, the user can continue smoking by coupling the holder 1 to the cradle 2.

[0168] The control unit 120 includes at least one processor. The processor may be implemented as a plurality of logic gate arrays or as a combination of a general-purpose microprocessor and a memory storing programs executable by the microprocessor. Furthermore, those skilled in the art will appreciate that the processor may also be implemented in other forms of hardware.

[0169] On the one hand, in addition to the battery 210 and the control unit 220, the bracket 2 may also include a common structure. For example, the bracket 2 may have a display that can output visual information. For example, when the bracket 2 has a display, the control unit 220 generates a signal for display on the display, thereby transmitting to the user information related to the battery 210 (e.g., the remaining capacity of the battery 210, whether it can be used, etc.), information related to resetting the bracket 2 (e.g., reset timing, resetting in progress, reset completed, etc.), information related to cleaning of the holder 1 (e.g., cleaning timing, cleaning required, cleaning in progress, cleaning completed, etc.), information related to charging of the bracket 2 (e.g., charging required, charging in progress, charging completed, etc.), etc. The display can be an embodiment of the output unit 140 described above.

[0170] In addition, the bracket 2 may include: at least one input device (e.g., a button) for the user to control the functions of the bracket 2; a terminal 2260 combined with the holder 1 and / or an interface for charging the battery 210 (e.g., a USB port, etc.).

[0171] For example, the user can use the input device of the tray 2 to perform various functions. By adjusting the number of times or the duration of pressing the input device, the user can perform a desired function of the multiple functions of the tray 2. By activating the input device, the user can cause the tray 2 to perform functions such as preheating the heater 2130 of the holder 1, adjusting the temperature of the heater 2130 of the holder 1, cleaning the space within the holder 1 for inserting cigarettes, checking whether the tray 2 is in an operable state, displaying the remaining power (available power) of the battery 210 of the tray 2, and resetting the tray 2. However, the functions of the tray 2 are not limited to the above examples.

[0172] Figure 14a and Figure 14b This is a diagram showing an example of a bracket from multiple side surfaces.

[0173] Figure 14a 2 is a diagram showing an example of a bracket 2 viewed from a first direction. A space 2230 is provided on one side of the bracket 2 for inserting the holder 1. Furthermore, even if the bracket 2 does not have a separate fixing means such as a cover, the holder 1 can be inserted and fixed to the bracket 2. Furthermore, the bracket 2 may include buttons 2240 for user control of the bracket 2 and a display 2250 for outputting images.

[0174] Figure 14b 2 is a diagram showing an example of a bracket 2 viewed from a second direction. The bracket 2 may include a terminal 2260 coupled to the inserted holder 1. The terminal 2260 is coupled to the terminal 2170 of the holder 1, and the power supplied by the battery 210 of the bracket 2 can charge the battery 110 of the holder 1. In addition, the power supplied by the battery 210 of the bracket 2 via the terminal 2170 and the terminal 2260 can operate the holder 1 and enable signal transmission / reception between the holder 1 and the bracket 2. For example, the terminal 2260 may include four micro-pins, but is not limited thereto.

[0175] As reference Figures 11 to 14b As described above, the retainer 1 can be inserted into the inner space 2230 of the bracket 2. In addition, the retainer 1 can be completely inserted into the inner space of the bracket 2 and can be tilted (tilted) when inserted into the bracket 2. Figures 15 to 17b , an example in which the retainer 1 is inserted into the bracket 2 will be described.

[0176] Figure 15 This is a diagram showing an example of inserting a holder into a bracket.

[0177] Reference Figure 15, showing an example of retainer 1 being inserted into bracket 2. Since a space 2230 for inserting retainer 1 is designed on one side of bracket 2, the inserted retainer 1 is not exposed to the outside from the other side of bracket 2. Therefore, bracket 2 does not need to have other structures (e.g., a cover) to prevent retainer 1 from being exposed to the outside.

[0178] The bracket 2 may have at least one coupling member 2271, 2272 for improving the coupling strength with the holder 1. In addition, the holder 1 also has at least one coupling member 2181. Here, the coupling members 2181, 2271, 2272 may be magnets, but are not limited thereto. Figure 15 In the figure, for the convenience of description, the holder 1 is shown to have one coupling member 2181 and the bracket 2 is shown to have two coupling members 2271 and 2272, but the number of coupling members 2181, 2271 and 2272 is not limited thereto.

[0179] The holder 1 may have a coupling member 2181 at the first position, and the bracket 2 may have coupling members 2271 and 2272 at the second and third positions, respectively.

[0180] Retainer 1 and bracket 2 have coupling members 2181, 2271, and 2272. Therefore, even if retainer 1 is inserted into one side of bracket 2, retainer 1 and bracket 2 can be more securely coupled. In other words, in addition to terminals 2170 and 2260, retainer 1 and bracket 2 also have coupling members 2181, 2271, and 2272, thereby enabling a more secure coupling between retainer 1 and bracket 2. Therefore, even if bracket 2 does not have a separate structure (e.g., a cover), an inserted retainer 1 will not easily separate from bracket 2.

[0181] Furthermore, when it is determined that the holder 1 is completely inserted into the bracket 2 via the terminals 2170 , 2260 and / or the coupling members 2181 , 2271 , 2272 , the control unit 220 can charge the battery 110 of the holder 1 using the power of the battery 210 .

[0182] Figure 16 This is a diagram showing an example of a state where the retainer is inserted into the bracket and tilted.

[0183] Reference Figure 16 , the retainer 1 tilts from the inside of the bracket 2. Here, tilting means that the retainer 1 is tilted at a predetermined angle in a state in which the retainer 1 is inserted into the bracket 2.

[0184] like Figure 15As shown, when the holder 1 is fully inserted into the bracket 2, the user cannot smoke. In other words, when the holder 1 is fully inserted into the bracket 2, the cigarette cannot be inserted into the holder 1. Therefore, when the holder 1 is fully inserted into the bracket 2, the user cannot smoke.

[0185] like Figure 16 As shown, when the holder 1 is tilted, the end 2141 of the holder 1 is exposed to the outside. The user can then insert a cigarette into the end 2141 and inhale the generated aerosol (smoke). The tilt angle θ should be large enough to prevent the cigarette from being broken or damaged when inserted into the end 2141 of the holder 1. For example, the holder 1 can be tilted to an extent that the entire cigarette insertion hole provided at the end 2141 is exposed to the outside. For example, the tilt angle θ can range from greater than 0° to less than 180°, and preferably, it can range from greater than 10° to less than 90°. More preferably, the tilt angle θ can range from greater than 10° to less than 20°, greater than 10° to less than 30°, greater than 10° to less than 40°, greater than 10° to less than 50°, or greater than 10° to less than 60°.

[0186] Furthermore, even when the holder 1 is tilted, the terminals 2170 of the holder 1 remain engaged with the terminals 2260 of the bracket 2. Therefore, the heater 2130 of the holder 1 can be heated by the power supplied by the battery 210 of the bracket 2. Therefore, even when the remaining power of the battery 110 of the holder 1 is low or absent, the holder 1 can generate aerosol using the battery 210 of the bracket 2.

[0187] Figure 16 , the example in which the retainer 1 includes one coupling member 2182 and the bracket 2 includes two coupling members 2273 and 2274 is shown. For example, the positions of the coupling members 2182, 2273, and 2274 are as shown in FIG. Figure 15 Assuming that the coupling members 2182, 2273, and 2274 are magnets, the magnetic field strength of the coupling member 2274 can be greater than the magnetic field strength of the coupling member 2273. Therefore, even if the retainer 1 tilts, the retainer 1 will not be completely separated from the bracket 2 due to the coupling members 182 and 2274.

[0188] Furthermore, when it is determined that the holder 1 is tilted by the terminals 2170 , 2260 and / or the coupling members 2182 , 2273 , 2274 , the control unit 220 may heat the heater 2130 of the holder 1 or charge the battery 110 using power from the battery 210 .

[0189] Figures 17a to 17b This is a diagram showing an example of inserting a holder into a bracket.

[0190] Figure 17a 2 shows an example in which the holder 1 is fully inserted into the bracket 2. The internal space 2230 of the bracket 2 is designed to be sufficient to minimize user contact with the holder 1 when the holder 1 is fully inserted into the bracket 2. When the holder 1 is fully inserted into the bracket 2, the control unit 220 causes the battery 210 to supply power to the holder 1, thereby charging the battery 110 of the holder 1.

[0191] Figure 17b 2 shows an example in which the holder 1 is tilted while being inserted into the bracket 2. When the holder 1 tilts, the control unit 220 causes the battery 210 to supply power 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.

[0192] Figure 18 This is a flowchart for explaining an example of the operation of the retainer and the bracket.

[0193] Figure 18 The method of generating aerosols shown includes Figure 11 The holder 1 shown or Figure 13 Therefore, in the following, even if the contents are omitted, the following Figure 11 The retainer 1 shown and Figure 13 The bracket 2 shown above is still applicable to Figure 18 method.

[0194] In step 2710, it is determined whether the holder 1 is inserted into the bracket 2. For example, the control unit 120 can determine whether the holder 1 is inserted into the bracket 2 based on whether the terminals 2170 and 2260 of the holder 1 and the bracket 2 are connected to each other and / or whether the coupling members 2181, 2271, and 2272 are actuated.

[0195] If the holder 1 has been inserted into the bracket 2 , proceed to step 2720 ; if the holder 1 has been separated from the bracket 2 , proceed to step 2730 .

[0196] In step 2720, the bracket 2 determines whether the retainer 1 is tilted. For example, the control unit 220 can determine whether the retainer 1 is tilted based on whether the terminals 2170 and 2260 of the retainer 1 and bracket 2 are connected to each other and / or whether the coupling members 2182, 2273, and 2274 are actuated.

[0197] Although the case where the bracket 2 determines whether the holder 1 is tilted in step 2720 has been described, the present invention is not limited thereto. In other words, the controller 120 of the holder 1 may determine whether the holder 1 is tilted.

[0198] If the retainer 1 is tilted, proceed to step 2740 ; if the retainer 1 is not tilted (ie, the retainer 1 is completely inserted into the bracket 2 ), proceed to step 2770 .

[0199] In step 2730, the holder 1 determines whether the use conditions of the holder 1 are met. For example, the control unit 120 determines whether the use conditions are met by confirming the remaining charge of the battery 110 and whether other components of the holder 1 are functioning normally.

[0200] If the use conditions of the retainer 1 are met, the process proceeds to step 2740; if not, the process ends.

[0201] In step 2740, the holder 1 notifies the user that it is in a usable state. For example, the control unit 120 may output an image indicating that it is in a usable state to the display of the holder 1, or may control the motor of the holder 1 to generate a vibration signal.

[0202] In step 2750, heater 2130 is heated. As an example, when holder 1 is separated from bracket 2, heater 2130 can be heated by power from battery 110 of holder 1. As another example, when holder 1 is tilted, heater 2130 can be heated by power from battery 210 of bracket 2.

[0203] The controller 120 of the holder 1 or the controller 220 of the carriage 2 can monitor the temperature of the heater 2130 in real time to adjust the amount of power supplied to the heater 2130 and the duration of power supply to the heater 2130. For example, the controllers 120 and 220 can monitor the temperature of the heater 2130 in real time using a temperature detection sensor in the holder 1 or a conductive track of the heater 2130.

[0204] In step 2760, the holder 1 executes the aerosol generation mechanism. For example, the control unit 120 or 220 adjusts the power supplied to the heater 2130 or interrupts the power supply to the heater 2130 by detecting the temperature of the heater 2130 changing with the user's puffs. Furthermore, the control unit 120 or 220 may count the number of puffs taken by the user and, when a predetermined number of puffs (e.g., 1500) is reached, output a message indicating that the holder needs to be cleaned.

[0205] In step 2770 , the cradle 2 charges the holder 1 . For example, the control unit 220 may charge the holder 1 by supplying power from the battery 210 of the cradle 2 to the battery 110 of the holder 1 .

[0206] On the other hand, the control unit 120, 220 can also stop the holder 1 according to the number of puffs taken by the user or the operation time of the holder 1. Figure 19 An example in which the control units 120 and 220 stop the retainer 1 will be described.

[0207] Figure 19 This is a flowchart for explaining another example of the retainer operation.

[0208] Figure 19 The method of generating aerosols shown includes Figure 11 The retainer 1 shown and Figure 13 Therefore, in the following, even if the contents are omitted, the following Figure 11 The holder 1 shown or Figure 13 The bracket 2 shown above is still applicable to Figure 19 method.

[0209] In step 2810 , the control unit 120 , 220 determines whether the user has inhaled. For example, the control unit 120 , 220 may determine whether the user has inhaled using a inhalation detection sensor in the holder 1 .

[0210] In step 2820, aerosol is generated by the user's inhalation. The control unit 120, 220 can adjust the power supplied to the heater 2130 according to the user's inhalation and the temperature of the heater 2130, as shown in FIG. Figure 18 In addition, the control units 120 and 220 count the number of puffs taken by the user.

[0211] In step 2830, the control unit 120, 220 determines whether the number of puffs taken by the user is greater than the puff limit. For example, if the puff limit is set to 14, the control unit 120, 220 determines whether the counted number of puffs is greater than 14.

[0212] On the other hand, when the number of puffs taken by the user approaches the puff limit (for example, when the number of puffs taken by the user is 12), the control unit 120 or 220 may output a warning signal via a display or a vibration motor.

[0213] If the number of puffs taken by the user is above the puff limit, the process proceeds to step 2850 . If the number of puffs taken by the user is below the puff limit, the process proceeds to step 2840 .

[0214] In step 2840, the control units 120 and 220 determine whether the operating time of retainer 1 is longer than the operating time limit. Here, the operating time of retainer 1 refers to the cumulative time from the time the retainer starts operating to the present time. For example, if the operating time limit is set to 10 minutes, the control units 120 and 220 determine whether retainer 1 has been operating for more than 10 minutes.

[0215] On the other hand, when the operating time of the holder 1 approaches the operating time limit (for example, when the holder 1 operates for 8 minutes), the control unit 120 or 220 may output a warning signal via a display or a vibration motor.

[0216] If the retainer 1 has been in operation for more than the operation limit time, the process proceeds to step 2850 . If the retainer 1 has been in operation for less than the operation limit time, the process proceeds to step 2820 .

[0217] In step 2850, the control unit 120, 220 forcibly terminates the operation of the holder. In other words, the control unit 120, 220 terminates the aerosol generation mechanism of the holder. For example, the control unit 120, 220 cuts off the power supply to the heater 2130, thereby forcibly terminating the operation of the holder.

[0218] Figure 20 This is a flowchart for explaining an example of the carriage operation.

[0219] Figure 20 The flowchart shown includes Figure 13 Therefore, in the following, even if the contents are omitted, the following Figure 13 The bracket 2 shown above is still applicable to Figure 20 Flowchart of the process.

[0220] Figure 20 Although not shown in the figure, the operation of the bracket 2 described below can be performed regardless of whether the holder 1 is inserted into the bracket 2 or not.

[0221] In step 2910 , the control unit 220 of the cradle 2 determines whether the button 2240 is pressed. If the button 2240 is pressed, the process proceeds to step 2920 . If the button 2240 is not pressed, the process proceeds to step 2930 .

[0222] In step 2920 , the cradle 210 displays the status of the battery. For example, the control unit 220 may output information about the current status (eg, remaining charge, etc.) of the battery 210 to the display 2250 .

[0223] In step 2930, the control unit 220 of the cradle 2 determines whether a cable is connected to the cradle 2. For example, the control unit 220 determines whether a cable is connected to the interface (e.g., USB port) of the cradle 2. If a cable is connected to the cradle 2, the process proceeds to step 2940; if not, the process ends.

[0224] In step 2940 , the cradle 2 performs a charging operation. For example, the cradle 2 charges the battery 210 using power supplied through the connected cable.

[0225] As reference Figure 11 As described above, a cigarette can be inserted into the holder 1. The cigarette contains an aerosol-generating substance, which is heated by the heater 2130 to generate an aerosol.

[0226] Below, refer to Figures 21 to 23f , illustrating a cigarette that can be inserted into the holder 1.

[0227] Figure 21 This is a diagram showing an example of a cigarette being inserted into a holder.

[0228] Reference Figure 21 The cigarette 3 can be inserted into the holder 1 through the end 2141 of the housing 2140. When the cigarette 3 is inserted, the heater 2130 is located inside the cigarette 3. Therefore, the heated heater 2130 heats the aerosol-generating substance of the cigarette 3, thereby generating an aerosol.

[0229] The cigarette 3 can be similar to a conventional combustion-type cigarette. For example, the cigarette 3 can be divided into a first portion 3310 containing an aerosol-generating substance and a second portion 3320 having a filter, etc. In one aspect, the cigarette 3 of one embodiment can contain an aerosol-generating substance in the second portion 3320. For example, the aerosol-generating substance in the form of particles or capsules can be inserted into the second portion 3320.

[0230] The entire first portion 3310 is inserted into the holder 1, while the second portion 3320 is exposed to the outside. Alternatively, only a portion of the first portion 3310 may be inserted into the holder 1, or portions of both the first portion 3310 and the second portion 3320 may be inserted.

[0231] The user can hold the second portion 3320 in the mouth and inhale the aerosol. At this time, the aerosol is mixed with the external air and then delivered to the user's mouth. Figure 21 As shown, external air can flow in (3110) through at least one hole formed on the surface of the cigarette 3, and can flow in (3120) through at least one air channel formed in the holder 1. For example, the air channel formed in the holder 1 can be made to be openable and closable by the user.

[0232] Figure 22a and Figure 22b This is a structural diagram showing an example of a cigarette.

[0233] Reference Figure 22a and Figure 22b The cigarette 3 includes a tobacco rod 3300, a first filter segment 3321, a cooling structure 3322 and a second filter segment 3323. Figure 21 The illustrated first portion 3310 includes a tobacco rod 3300 , and the second portion 3320 includes a first filter segment 3321 , a cooling structure 3322 , and a second filter segment 3323 .

[0234] On the one hand, Figure 22a and Figure 22b to compare with Figure 22b Cigarette 3, Figure 22a The cigarette 3 further includes a fourth wrapping paper 3334 .

[0235] only, Figure 22a and Figure 22b The structure of the cigarette 3 shown is merely an example, and some of the structures may be omitted. For example, one or more of the first filter segment 3321, the cooling structure 3322, and the second filter segment 3323 in the cigarette 3 may be omitted.

[0236] The tobacco rod 3300 contains an aerosol-generating substance. For example, the aerosol-generating substance may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. The length of the tobacco rod 3300 may be approximately 7 mm to 15 mm, preferably approximately 12 mm. Furthermore, the diameter of the tobacco rod 3300 may be 7 mm to 9 mm, preferably approximately 7.9 mm. The length and diameter of the tobacco rod 3300 are not limited to the aforementioned numerical ranges.

[0237] In addition, the tobacco stick 3300 may include flavorings, humectants, and / or other additives such as acetate compounds. For example, flavorings may include licorice, sucrose, fructose syrup, ISO sweetener, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, bittersweet, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, peppermint oil, cassia bark, caraway, cognac, jasmine, chamomile, menthol, cassia bark, ylang-ylang, sage, spearmint, ginger, coriander, or coffee. In addition, humectants may include glycerin or propylene glycol.

[0238] As an example, the tobacco rod 3300 may be filled with tobacco leaves. Here, the tobacco leaves may be produced by chopping tobacco sheets.

[0239] In order to fill the narrow tobacco rod 3300 with wide tobacco sheets, a special process may be required to facilitate folding the tobacco sheets. Therefore, filling the tobacco rod 3300 with tobacco leaves is easier than filling the tobacco rod 3300 with tobacco sheets, and the process of producing the tobacco rod 3300 may be more productive and efficient.

[0240] As another example, tobacco rod 3300 may be filled with multiple tobacco shreds obtained by shredding tobacco sheets. For example, tobacco rod 3300 may be formed by combining multiple tobacco shreds in the same direction (parallel) or randomly. A single tobacco shred may be formed into a rectangular parallelepiped with a horizontal length of 1 mm, a vertical length of 12 mm, and a thickness (height) of 0.1 mm, but is not limited thereto.

[0241] Compared to tobacco rod 3300 filled with tobacco sheets, tobacco rod 3300 filled with shredded tobacco is likely to generate more aerosol. Assuming the same space is filled, shredded tobacco provides a wider surface area than tobacco sheets. This wider surface area means that aerosol-generating substances have more opportunities to come into contact with the outside air. Therefore, tobacco rod 3300 filled with shredded tobacco is likely to generate more aerosol than tobacco sheets.

[0242] Furthermore, when separating the cigarette 3 from the holder 1, a tobacco rod 3300 filled with shredded tobacco may be easier to separate than one filled with tobacco sheets. The friction generated by the contact between shredded tobacco and the heater 2130 is lower than that generated by tobacco sheets. Therefore, a tobacco rod 3300 filled with shredded tobacco can be more easily separated from the holder 1 than one filled with tobacco sheets.

[0243] Tobacco sheets can be formed by pulverizing tobacco raw materials into a slurry and then drying the slurry. For example, 15 to 30% of an aerosol-forming substance may be added to the slurry. The tobacco raw materials may include tobacco scraps, tobacco stems, tobacco dust generated during tobacco processing, and / or the main leaves and stems of tobacco leaves. Furthermore, the tobacco sheets may contain other additives such as wood cellulose.

[0244] The first filter segment 3321 can be a cellulose acetate filter. For example, the first filter segment 3321 can be tubular with a hollow hole inside. The length of the first filter segment 3321 can be about 7 mm to 15 mm, preferably about 7 mm. The length of the first filter segment 3321 can be shorter than about 7 mm, but preferably has a length that impairs the function of at least one cigarette element (for example, a cooling element, a capsule, an acetate filter, etc.). The length of the first filter segment 3321 is not limited to the aforementioned numerical range. On the one hand, the length of the first filter segment 3321 can be lengthened, and the overall length of the cigarette 3 can be adjusted according to the length of the first filter segment 3321.

[0245] The second filter segment 3323 can be a cellulose acetate filter. For example, the second filter segment 3323 can be fabricated as a hollow, grooved filter, but is not limited thereto. The length of the second filter segment 3323 can be approximately 5 mm to 15 mm, preferably approximately 12 mm. The length of the second filter segment 3323 is not limited to the aforementioned range.

[0246] Additionally, the second filter segment 3323 may include at least one capsule 3324. Here, the capsule 3324 may be a structure that encloses the flavoring-containing contents with a membrane. For example, the capsule 3324 may have a spherical or cylindrical shape. The diameter of the capsule 3324 may be greater than 2 mm, preferably 2 to 4 mm.

[0247] The material forming the membrane of capsule 3324 can be starch and / or a gelling agent. For example, gellan gum or gelatin can be used as the gelling agent. Furthermore, a gelling agent (auxiliary agent) can be further used as the membrane material forming capsule 3324. Here, as a gelling agent, for example, calcium chloride can be used. In addition, as a material forming the membrane of capsule 3324, a plasticizer can be further used. Here, as a plasticizer, glycerin and / or sorbitol can be used. In addition, as a material forming the membrane of capsule 3324, a coloring material can be further used.

[0248] For example, peppermint oil, plant essential oils, etc. can be used as flavoring agents contained in the liquid content of the capsule. In addition, as a solvent for the flavoring agents contained in the liquid content, for example, medium-chain triglycerides (MCT) can be used. In addition, the liquid content may contain other additives such as pigments, emulsifiers, and thickeners.

[0249] The cooling structure 3322 cools the aerosol generated by heating the tobacco rod 3300 by the heater 2130 . This allows the user to inhale the aerosol cooled to a suitable temperature. The length of the cooling structure 3322 can be approximately 10 mm to 20 mm, preferably approximately 14 mm. The length of the cooling structure 3322 is not limited to the aforementioned range.

[0250] For example, the cooling structure 3322 can be made of polylactic acid. In order to increase the surface area per unit area (i.e., the surface area in contact with the aerosol), the cooling structure 3322 can be made into various shapes. For various examples of the cooling structure 3322, see Figures 23a to 23f This will be described later.

[0251] The tobacco rod 3300 and the first filter segment 3321 may be wrapped by a first wrapping paper 3331. For example, the first wrapping paper 3331 may be made of an oil-resistant paper-based packaging material.

[0252] The cooling structure 3322 and the second filter segment 3323 can be wrapped in a second wrapping paper 3332. Furthermore, the entire cigarette 3 can be further wrapped in a third wrapping paper 3333. For example, the second wrapping paper 3332 and the third wrapping paper 3333 can be made of conventional paper packaging materials. Alternatively, the second wrapping paper 3332 can be oil-resistant rigid wrapping paper or PLA flavored paper. Furthermore, the second wrapping paper 3332 partially wraps the second filter segment 3323 and, further, can also wrap the second filter segment 3323 and the cooling structure 3322.

[0253] Reference Figure 22b The cigarette 3 may further be wrapped with a fourth wrapping paper 3334. At least one of the tobacco rod 3300 and the first filter segment 3321 may be wrapped with the fourth wrapping paper 3334. In other words, only the tobacco rod 3300 may be wrapped with the fourth wrapping paper 3334, while the tobacco rod 3300 and the first filter segment 3321 may be wrapped with the fourth wrapping paper 3334. For example, the fourth wrapping paper 3334 may be made of a paper-based packaging material.

[0254] The fourth wrapping paper 3334 can be produced by applying (or coating) a predetermined substance to one or both surfaces of the paper-based packaging material. An example of the predetermined substance is, but is not limited to, silicone. Silicone has properties such as heat resistance with minimal temperature fluctuations, oxidation resistance, resistance to various chemicals, hydrophobicity, and electrical insulation. However, any substance other than silicone, as long as it possesses the aforementioned properties, can be applied (or coated) to the fourth wrapping paper 3334.

[0255] on the one hand, Figure 22b In FIG. 3 , the cigarettes 3 are shown to include the first wrapping paper 3331 and the fourth wrapping paper 3334 , but the present invention is not limited thereto. In other words, the cigarettes 3 may include only one of the first wrapping paper 3331 and the fourth wrapping paper 3334 .

[0256] The fourth wrapping paper 3334 can prevent the cigarette 3 from burning. For example, when the tobacco rod 3300 is heated by the heater 2130, the cigarette 3 may burn. Specifically, if the temperature rises to the ignition point of any substance contained in the tobacco rod 3300, the cigarette 3 may burn. Even in this case, the fourth wrapping paper 3334 contains a non-combustible material, thus preventing the cigarette 3 from burning.

[0257] Furthermore, the fourth wrapping paper 3334 prevents contamination of the retainer 1 by substances generated within the cigarette 3. Liquid substances may form within the cigarette 3 as the user inhales. For example, the aerosol generated within the cigarette 3 may be cooled by the outside air, potentially generating liquid substances (e.g., moisture). By wrapping the tobacco rod 3300 and / or the first filter segment 3321, the fourth wrapping paper 3334 prevents liquid substances generated within the cigarette 3 from leaking outside the cigarette 3. This prevents contamination of the retainer 1 housing 2140 and other components by liquid substances generated within the cigarette 3.

[0258] Figures 23a to 23f This is a diagram showing an example of a cigarette cooling structure.

[0259] For example, Figures 23a to 23f The cooling structure shown in FIG can be made using fibers produced from pure polylactic acid (PLA).

[0260] For example, when a film (sheet) is filled to form a cooling structure, the film (sheet) may be shattered by external impact, which reduces the cooling effect of the cooling structure on the aerosol.

[0261] As another example, when manufacturing a cooling structure by extrusion molding, the process efficiency is reduced due to the addition of steps such as cutting the structure. In addition, there are limitations in manufacturing the cooling structure in various shapes.

[0262] The cooling structure of one embodiment is made of polylactic acid fibers (e.g., woven), thereby reducing the risk of deformation or loss of function of the cooling structure due to external impact. In addition, by changing the combination of fibers, cooling structures with various shapes can be produced.

[0263] Furthermore, by using fibers to create the cooling structure, the surface area in contact with the aerosol is increased, thereby further enhancing the aerosol cooling effect of the cooling structure.

[0264] Reference Figure 23a The cooling structure 3510 can be made into a cylindrical shape, and can be made into a shape such that at least one air channel 3511 is formed on the end surface of the cooling structure 3510 .

[0265] Reference Figure 23b Cooling structure 3520 can be fabricated as a structure with multiple interwoven fibers. This allows aerosol to flow between the fibers, forming eddies based on the shape of cooling structure 3520. These eddies expand the area of ​​contact with the aerosol within cooling structure 3520, increasing the time the aerosol remains within cooling structure 3520. This effectively cools the heated aerosol.

[0266] Reference Figure 23c The cooling structure 3530 can be made into a shape in which multiple bundles 3531 are closed together.

[0267] Reference Figure 23d The cooling structure 3540 can be filled with particles made from polylactic acid, tobacco, or charcoal. Alternatively, the particles can be made from a mixture of polylactic acid, tobacco, and charcoal. In addition to polylactic acid, tobacco, and / or charcoal, the particles can also contain elements that enhance the cooling effect of the aerosol.

[0268] Reference Figure 23e The cooling structure 3550 may include a first end surface 3551 and a second end surface 3552 .

[0269] The first end surface 3551 borders the first filter segment 3321 and may include pores for aerosol inflow. The second end surface 3552 borders the second filter segment 3323 and may include pores for aerosol discharge. For example, the first end surface 3551 and the second end surface 3552 may include a single pore of the same diameter, but the diameter and number of pores included in the first end surface 3551 and the second end surface 3552 are not limited to this.

[0270] Furthermore, the cooling structure 3550 may have a third end surface 3553 between the first end surface 3551 and the second end surface 3552. The third end surface 3553 may include a plurality of pores. For example, the diameters of the pores in the third end surface 3553 may be smaller than the diameters of the pores in the first end surface 3551 and the second end surface 3552. Furthermore, the number of pores in the third end surface 3553 may be greater than the number of pores in the first end surface 3551 and the second end surface 3552.

[0271] Reference Figure 23f The cooling structure 3560 may include a first end face 3561 that is adjacent to the first filter segment 3321 and a second end face 3562 that is adjacent to the second filter segment 3323. In addition, the cooling structure 3560 may include one or more tubular components 3563. For example, the tubular component 3563 may pass through the first end face 3561 and the second end face 3562. In addition, the tubular component 3563 may be wrapped with a microporous packaging material and filled with a filling material that can improve the cooling effect of the aerosol (for example, see Figure 23d The particles) are filled.

[0272] As described above, the holder heats the cigarettes to generate aerosol. Furthermore, the holder can generate aerosol when used alone or when inserted into the holder and tilted sideways. In particular, when the holder is tilted sideways, the heater can be heated by power from the holder's battery.
