Description

Technical Field

[0001] The present invention relates to an aerosol generating device and an aerosol generating system.

[0002] In particular, the present invention relates to an aerosol generating device and an aerosol generating system that can operate in various modes to provide various tastes, flavors, and the like.

Background Art

[0003] Generally, tobacco refers to a perennial herb of the Solanaceae family in the order Dicotyledoneae. Recently, products made by wrapping tobacco leaves with rolling paper and having a filter part on one side for the purpose of smoking are also commonly referred to. Such tobacco has reached thousands of varieties worldwide and is sold in various shapes and forms.

[0004] The taste, irritation, etc. of tobacco are determined by the materials and manufacturing processes. Recently, tobacco that overcomes such drawbacks and utilizes auxiliary devices that can supplement various tastes and flavors has been developed, and such auxiliary devices have received positive evaluations from users and the demand is increasing.

[0005] The auxiliary device is generally utilized in a manner of fixing a dedicated tobacco, heating the dedicated tobacco, heating the liquid stored inside to create and supply an aerosol. When smoking using the auxiliary device, even if the dedicated tobacco is heated to a low temperature, insufficient aerosol can be artificially supplied, and the user satisfaction is high.

[0006] However, recently, problems have been raised regarding tobacco that utilizes an auxiliary device, and there is a growing voice that improvement is needed.

[0007] The first problem is that a liquid is essential.

[0008] When using the auxiliary device, the tobacco is heated to a low temperature, so an aerosol is essential to transport the substance for it to be supplied to the user. This means that a liquid for aerosol generation is essential. Therefore, a disadvantage was that if there was a shortage of liquid, the user could not operate the auxiliary device and receive the substance. In particular, the problem arose that the device could not operate without liquid during times when it was not possible to purchase liquid, such as early morning or late at night.

[0009] The second problem is that the taste and flavor are predetermined.

[0010] One reason for using auxiliary devices is to accommodate a variety of tastes and flavors, but since auxiliary devices heat to a predetermined temperature to provide an aerosol, they could only provide a fixed taste and flavor. [Overview of the Initiative] [Problems that the invention aims to solve]

[0011] The present invention, in one embodiment, aims to provide an aerosol generating device and aerosol generating system that can operate in various modes while solving the above-mentioned problems.

[0012] In other words, according to one embodiment of the present invention, the objective is to provide an aerosol generating device and aerosol generating system that can operate in such a way that tobacco substances reach the user even when there is a shortage of liquid.

[0013] Furthermore, the present invention, according to one embodiment, aims to provide an aerosol generating device and aerosol generating system that have a wide range of heating temperatures and apply heat to tobacco at various temperatures, allowing users to enjoy a variety of tastes and flavors. [Means for solving the problem]

[0014] An aerosol generating apparatus according to one embodiment includes a housing, a draw-in hole formed on one side of the housing into which aerosol products are drawn, a liquid storage section located adjacent to the draw-in hole and storing liquid, and a heating section that applies heat to the liquid storage section and the draw-in hole so that the aerosol products are burned, wherein the heating section applies heat to the liquid storage section and the draw-in hole, or applies heat to the draw-in hole.

[0015] The heating unit includes a first heater that applies heat to the liquid storage unit and a second heater that applies heat to the intake hole, wherein when the first heater and the second heater operate simultaneously, the second heater operates to apply heat at a first temperature, and when the second heater operates, it operates to apply heat at a second temperature higher than the first temperature.

[0016] The first temperature is 120 degrees or higher, and the second temperature is at least 40 degrees higher than the first temperature.

[0017] The first temperature is characterized by being between 120°C and 200°C, and the second temperature is characterized by being between 160°C and 280°C.

[0018] The second heater is heated if the amount of liquid in the liquid storage section is less than a preset amount.

[0019] The housing is equipped with a detection sensor unit for detecting the aerosol product being drawn into the intake hole, and when the detection sensor unit detects a preset aerosol product, the second heater is heated.

[0020] An aerosol generation system according to one embodiment may include a housing, a draw-in hole formed on one side of the housing, a liquid storage section provided within the housing for storing a liquid that is converted into an aerosol when heated, a heating section that allows heat to be applied to the liquid storage section and the draw-in hole simultaneously, or only to the draw-in hole, and an aerosol product in which a medium section, which is drawn into the draw-in hole and positioned corresponding to the portion to which the heating section applies heat, is filled with 10% or more of a humectant.

[0021] The aerosol product may include a cooling section in which a plurality of perforated holes are formed on one side of the medium portion.

[0022] The cooling section is characterized by having a hollow interior and multiple segments arranged in a row, each having multiple perforated holes that penetrate the inside and outside.

[0023] The present invention further includes a detection sensor unit for detecting aerosol products being drawn into the intake hole, and when the detection sensor unit detects the aerosol products including the cooling unit, the heating unit operates to apply heat only to the intake hole.

[0024] The heating unit includes a first heater that applies heat to the liquid storage unit and a second heater that applies heat to the intake hole, wherein when the first heater and the second heater operate simultaneously, the second heater operates to apply heat at a first temperature, and when the second heater operates, it operates to apply heat at a second temperature higher than the first temperature.

[0025] The second temperature is between 160°C and 280°C, and the cooling section is characterized in that air is drawn in through the perforated holes, and the aerosol generated in the medium section is mixed with the air and diluted by 10% or more before being cooled. [Effects of the Invention]

[0026] The present invention according to one embodiment can operate in various modes such as dual mode and single mode to generate and supply aerosol.

[0027] According to one embodiment of the present invention, when the liquid is insufficient, the single mode operates, and even without liquid, it can supply aerosol and substances to the user. Therefore, even when the liquid is insufficient, the user can feel the taste and flavor of tobacco.

[0028] Also, according to one embodiment of the present invention, since aerosol is generated by various temperature changes such as dual mode and single mode, it can provide diverse tastes and flavors to the user.

Modes for Carrying Out the Invention

[0030] Hereinafter, an embodiment of the present invention will be described in detail with reference to illustrative drawings. However, this is not intended to limit the scope of the present invention.

[0031] When assigning reference numerals to the components in each drawing, it should be noted that, as far as possible, identical components should have the same reference numeral even if they are shown in other drawings. Furthermore, when describing the present invention, if it is determined that a specific description of such known configurations or functions may obscure the gist of the present invention, such detailed description will be omitted.

[0032] Furthermore, the size and shape of the components shown in the drawings may be exaggerated for clarity and convenience in the explanation. Also, terms specifically defined in consideration of the structure and operation of the present invention are merely for the purpose of describing embodiments of the present invention and do not limit the scope of the present invention.

[0033] The following describes an aerosol generating apparatus according to the first embodiment of the present invention.

[0034] Figure 1 is a structural diagram of an aerosol generating apparatus according to the first embodiment of the present invention.

[0035] Referring to Figure 1, the aerosol generating device 100 according to the first embodiment may include a housing 110, a battery 120, a liquid storage unit 130, a heating unit 140 (first heater 141 and second heater 145), a retraction hole 150, a control unit 160, and a detection sensor unit 170.

[0036] The housing 110 is a device that forms the outer shape of the aerosol generating device 100 of the present invention, and various electronic devices and articles can be arranged and stored inside. The aforementioned components may be fixedly arranged inside the housing 110, and the aerosol product 200 (see Figures 6 to 8), described later, can be fixed in the draw-in hole 150. The housing 110 is sturdily formed so that the user can grip it tightly with their hand when smoking.

[0037] The battery 120 may be located on one side inside the housing 110. The battery 120 stores power and can supply power when needed. The battery 120 is connected to the heating unit 140 and the control unit 160, and the control unit 160 can supply power to the first heater 141 and the second heater 145 constituting the heating unit 140, or to the second heater 145, according to the control signals of the control unit 160.

[0038] The liquid storage unit 130 is located inside the housing 110. Although not shown in the drawings, the liquid storage unit 130 can be detachably coupled to the housing 110. The liquid storage unit 130 may include a liquid composition and a liquid transfer means. When the liquid storage unit 130 is heated by the heating unit 140, the liquid composition is heated and an aerosol can be generated.

[0039] The liquid composition may be a liquid containing tobacco-containing substances that include volatile tobacco flavor components, or it may be a liquid containing non-tobacco substances.

[0040] The liquid composition may contain water, solvent, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures. Here, the fragrances may include, but are not limited to, menthol, peppermint, spearmint oil, and various fruit fragrance components. The flavorings may include components that can provide users with a variety of flavors or aromas. The vitamin mixture may be, but is not limited to, a mixture of at least one of vitamins A, B, C, and E. Additionally, the liquid composition may contain aerosol-forming agents such as glycerin and propylene glycol.

[0041] Furthermore, a liquid transfer means (not shown) of the liquid storage section 130 can transfer the liquid composition of the liquid storage section 130 to the heating section 140 (first heater 141). For example, the liquid transfer means may be a wick made of cotton fibers, ceramic fibers, glass fibers, or porous ceramic, but is not limited thereto. The liquid transfer means can be modified in various ways, but as an example, the wick may be placed inside the liquid storage section 130 and formed in such a shape that one side contacts the heating section 140 while absorbing the liquid.

[0042] On the other hand, although the drawing shows that the liquid storage section 130 and the intake hole 150 are not in communication, it should be noted that this is shown in the drawing for the sake of clarity in the explanation, and in reality they are in communication, allowing the aerosol generated in the liquid storage section 130 to be supplied to the intake hole 150.

[0043] The heating unit 140 receives power from the battery 120 inside the housing 110 and applies heat to the liquid storage unit 130 and the aerosol product 200 fixed in the intake hole 150 to enable aerosol generation. The heating unit 140 may include a first heater 141 for heating the liquid storage unit 130 and a second heater 145 for heating the medium portion 210 of the aerosol product 200 located in the intake hole 150.

[0044] When power is supplied, the first heater 141 applies heat to the liquid storage unit 130 at a set temperature, enabling the generation of an aerosol. The aerosol generated in the liquid storage unit 130 replenishes any deficient aerosol when the aerosol product 200 is heated to a low temperature, ensuring that the substances contained in the aerosol product 200 reach the user. The substances contained in the aerosol product include a variety of substances such as nicotine, flavorings, and aerosol-generating substances, which will be explained in more detail later when describing the aerosol product.

[0045] The first heater 141 may be a metal heating wire, a metal heating plate, a ceramic heater, etc., but is not limited thereto. The first heater 141 may also be composed of a conductive filament such as a nichrome wire, or it may be formed in a shape that winds around the liquid storage section 130.

[0046] The second heater 145 can apply heat to the medium portion 210 (see Figures 6 to 8) of the aerosol product 200. When heat is applied to the medium portion 210 of the aerosol product 200, nicotine (for example, freebase nicotine, nicotine salt) and an aerosol can be formed.

[0047] The second heater 145 may, for example, be formed to heat the susceptor when the susceptor is positioned facing the inlet hole 150 and a coil is arranged to surround it and supply power. Here, the susceptor may include at least one of ferrite, ferromagnetic alloy, stainless steel, and aluminum (Al).

[0048] Furthermore, the susceptor may also contain at least one of the following: graphite, molybdenum, silicon carbide, niobium, nickel alloy, metal film, ceramics such as zirconia, transition metals such as nickel (Ni) and cobalt (Co), and metalloids such as boron (B) and phosphorus (P).

[0049] In addition, the second heater 145 of the present invention is not limited to the example described above, and can be modified within reasonable limits (for example, a configuration such as a heater rod) as long as it is a means that can apply heat to the aerosol product 200.

[0050] On the other hand, the second heater 145 can be heated to either the first or second temperature depending on the mode (dual mode or single mode). The first temperature may be lower than the second temperature.

[0051] The first temperature is relatively lower than the second temperature and may be between 120°C and 200°C. More preferably, the first temperature may be between 120°C and 190°C.

[0052] The second temperature is relatively higher than the first temperature, and may be at least 160 degrees Celsius, which is 40 degrees higher than the lowest temperature of the first temperature, 120 degrees Celsius. In other words, the second temperature may be between 160 degrees Celsius and 280 degrees Celsius. More preferably, the second temperature may be between 180 degrees Celsius and 250 degrees Celsius.

[0053] The reason the second heater 145 is heated to the first temperature when in dual mode is that the aerosol formed by the liquid storage unit 130 assists in the transfer of substances burned in the aerosol product 200. In other words, when heat is applied to the liquid storage unit 130 and it is heated, even if the aerosol product 200 is heated to the first temperature, the substances contained in the aerosol product 200 can be transferred to the smoker.

[0054] Conversely, in single mode, when the liquid storage unit 130 is not heated, the amount of aerosol generated is reduced, so the transferability of the aerosol product 200 becomes very low, and the substances contained in the aerosol product 200 should not be able to transfer to the smoker.

[0055] Therefore, in single mode where only the second heater 145 is heated, the aerosol product 200 itself requires a high transfer force, so the second heater 145 can heat the aerosol product 200 to a second temperature to generate a large amount of aerosol.

[0056] The retraction hole 150 may be formed on one side of the housing 110. Through the retraction hole 150, the aerosol product 200 can be fixed in contact with the inner surface of the housing 110. Thus, the aerosol product 200 can be heated and burned by the second heater 145.

[0057] On the other hand, it goes without saying that the control unit 160, which will be described in detail below, can be omitted if necessary. That is, as mentioned above or below, the control of the control unit 160 can be automatically performed by calculating various signals and information even without the control unit 160. However, for the sake of explanation, the present invention will be described as being controlled by the control unit 160.

[0058] The control unit 160 applies control signals to the heating unit 140 to enable it to operate differently depending on whether it is in a preset dual mode or single mode.

[0059] When the control unit 160 is controlled to operate in dual mode, the control unit 160 can control the first heater 141 and the second heater 145 to be heated simultaneously. In dual mode, the control unit 160 may control the battery 120 to connect the first heater 141 and the second heater 145, and the second heater 145 may apply heat at a temperature corresponding to dual mode. In this case, the first heater 141 can be heated to a preset temperature (for example, between 200 and 250 degrees Celsius).

[0060] The second heater 145 can be heated to the first temperature when operating in dual mode. In this case, the aerosol is generated in the liquid storage unit 130 and moves through the draw-in hole 150, and the articles generated in the aerosol product 200 move along with the aerosol and can be supplied to the user.

[0061] When the control unit 160 is controlled to operate in single mode, the control unit 160 can be controlled so that only the second heater 145 is heated. Here, the control of the control unit 160 may be such that the battery 120 and the second heater 145 are connected so that the second heater 145 is heated to a second temperature.

[0062] Thus, the present invention allows a single device to offer users a variety of flavors through various modes, enabling them to experience a wide range of satisfaction.

[0063] The control unit 160 can automatically set dual mode or single mode depending on the aerosol product 200. For this purpose, the present invention may further include a detection sensor unit 170.

[0064] The detection sensor unit 170 is located inside the housing 110 and powered by the battery 120, and can distinguish and recognize the aerosol products 200 placed in the entry hole 150. On the other hand, the detection of the aerosol products 200 by the detection sensor unit 170 can mean distinguishing and recognizing the type of aerosol product 200.

[0065] For example, the detection sensor unit 170 may be a sensor that detects capacitance. Therefore, it is possible to recognize the aerosol product 200 by detecting a change in dielectric properties according to the amount of water contained in the aerosol product 200. In addition, the detection sensor unit 170 can operate in a manner that distinguishes and recognizes the aerosol product 200 by detecting the shape, color, etc. of the aerosol product 200.

[0066] The detection sensor unit 170 distinguishes and recognizes the aerosol product 200, and when it transmits a recognition signal to the control unit 160, the control unit 160 selects either dual mode or single mode and enables operation.

[0067] For example, assuming that aerosol product A is compatible with dual mode and aerosol product B is compatible with single mode, when the detection sensor unit 170 recognizes aerosol product A 200 and transmits an A recognition signal to the control unit 160, the control unit 160 can operate in dual mode. When the detection sensor unit 170 recognizes aerosol product B 200 and transmits a B recognition signal to the control unit 160, the control unit 160 can control the battery 120 and the heating unit 140 (temperature of the second heater 145), etc., to operate in single mode.

[0068] The reason why the control unit 160 operates in this way will be explained in detail later, but it is to ensure that the best possible flavor is achieved by considering the degree to which the aerosol generating substance fills the medium unit 210 relative to the aerosol product 200 and the degree of cooling of the cooling unit 220 (see Figures 6 to 8).

[0069] The following describes an aerosol generating apparatus according to a second embodiment of the present invention.

[0070] Figure 2 shows the structure and operation diagram of an aerosol generating apparatus according to a second embodiment of the present invention.

[0071] It should be understood that the aerosol generator 100 described in each of the embodiments described below includes a configuration similar to that of the aerosol generator 100 according to the first embodiment, unless otherwise described.

[0072] Referring to Figure 2, the aerosol generator 100 according to the second embodiment can further include a selection unit 180. In the aerosol generator 100 according to the second embodiment, the user can arbitrarily select either dual mode or single mode using the selection unit 180.

[0073] The selection unit 180 can be any configuration, such as a button, switch, touchscreen, or wireless device controlled wirelessly by a terminal. Therefore, the user draws the aerosol product 200 into the draw-in hole 150 and operates the selection unit 180 so that the control unit 160 can operate in either dual mode or single mode.

[0074] On the other hand, the aerosol generating device 100 according to the second embodiment may further include a warning unit 190 along with the selection unit 180. The warning unit 190 can be configured in any way that stimulates the five senses to give a specific warning to the user, such as lighting that emits a specific color, a screen, or a speaker that generates noise.

[0075] The warning unit 190 warns the user when the mode selected by the user via the selection unit 180 (either dual mode or single mode) is unsuitable for the aerosol product 200 drawn into the aerosol generator 100, allowing the user to recognize this. This is because if the aerosol generator 100 operates in the selected mode according to the substance filled in the aerosol product 200, the user will not be able to enjoy the flavor.

[0076] For example, if a user draws an aerosol product suitable for dual mode into the draw-in hole 150 and operates it using the selection unit 180 to operate in single mode, then the warning unit 190 can activate to inform the user that the aerosol product drawn into the aerosol generator 100 is unsuitable for single mode. Alternatively, the warning unit 190 may interrupt the operation of the aerosol generator 100.

[0077] For example, if a user draws an aerosol product suitable for dual mode into the intake hole 150 and uses the selection unit 180 to operate in single mode, the warning unit 190 can control the aerosol generator 100 so that it does not operate in single mode. Therefore, the user must select dual mode using the selection unit 180 for the aerosol generator 100 to operate and for the user to experience the flavor.

[0078] In this way, the warning unit 190 assists the selection unit 180 so that the user can operate the aerosol generator 100 properly.

[0079] The following describes an aerosol generating apparatus according to a third embodiment of the present invention.

[0080] Figure 3 shows the structure and operation method of an aerosol generating apparatus according to a third embodiment of the present invention.

[0081] Referring to Figure 3, the aerosol generator 100 according to the third embodiment can detect the amount of liquid stored in the liquid storage unit 130 and operate so that the control unit 160 operates in dual mode or single mode.

[0082] The amount of liquid stored in the liquid storage unit 130 can be measured by a measuring sensor unit 165 that detects another liquid. However, even without the measuring sensor unit 165, the control unit 160 itself can also detect the amount of liquid. For example, the control unit 160 can check the amount of liquid in the liquid control unit 160 by checking the number of times power is supplied to the first heater 141. In other words, the control unit 160 may have in advance the amount of liquid that decreases when the first heater 141 operates once.

[0083] When the amount of liquid in the liquid storage unit 130 is detected to be less than or equal to a preset amount, the control unit 160 can control the heating unit 140 (second heater 145) so that the aerosol generator 100 operates in single mode.

[0084] Therefore, even if there is no liquid in the liquid storage section 130, the user can still perceive the flavor using the aerosol generator 100.

[0085] The following describes an aerosol generating apparatus according to a fourth embodiment of the present invention.

[0086] Figure 4 shows the structure and operation method of an aerosol generating apparatus according to the fourth embodiment of the present invention.

[0087] Referring to Figure 4, the aerosol generating apparatus 100 according to the fourth embodiment may further include a timer unit 195.

[0088] The timer unit 195 can measure the current time. The control unit 160 allows only one of either single-mode or dual-mode operation to be performed depending on the time. For example, the aerosol generator 100 of the present invention is configured to operate in single mode during the first hour and in dual mode during the second hour. Here, the first hour may be between 7:00 AM and 8:00 AM, and the second hour may be any time other than the first hour.

[0089] Therefore, the present invention can operate without consuming liquid during times when it is difficult to purchase liquid or move around, such as early morning hours, thus providing convenience for the user. In addition, the first time may be one of several time intervals other than those described above (e.g., 7:00 AM to 8:00 AM, 10:00 PM to 11:00 PM).

[0090] On the other hand, in the case of the fourth embodiment, the aforementioned selection unit (180, see Figure 2) is also included, and it goes without saying that even during the time when only single mode is operating, the user can arbitrarily select dual mode for operation.

[0091] The aerosol generation system according to the first embodiment of the present invention will be described below.

[0092] Figure 5 shows the aerosol generation system according to the first embodiment.

[0093] Figure 6 is a partial cross-section of the aerosol product applied to the aerosol generation system shown in Figure 5.

[0094] The aerosol generation system according to the first embodiment may include one of the aerosol generators 100 described in Figures 1 to 4 and an aerosol product 200. The aerosol product 200 can compensate for the problems that occur when the aerosol generator 100 operates in single mode.

[0095] In this embodiment, the aerosol generator 100 of the present invention operates in single mode with only the second heater 145 heated to a second temperature. Conventional aerosol generators 100, even when operating in single mode, may not generate a sufficient amount of atomized material (aerosol volume), potentially leading to problems where the substances contained in the aerosol product 200 cannot be transmitted to the user. Furthermore, since a relatively high temperature is applied to the aerosol product 200, the user may experience discomfort caused by the high temperature.

[0096] The aerosol product 200 according to the example shown in Figure 6 solves these problems. When heated to a high temperature, a large amount of aerosol is generated, and the cooling unit 220 can achieve a high dilution rate (cooling). This allows the various substances contained in the aerosol product 200 to reach the user, and even when a high temperature is applied, sufficient cooling can be performed so that the user does not feel uncomfortable.

[0097] The aerosol product 200 of the present invention may include a medium section 210 and a cooling section 220.

[0098] When the medium section 210 is drawn into the intake hole 150 of the aerosol generating device 100, it is positioned to correspond to the second heater 145. The medium section 210 can be heated by the second heater 145 to generate an aerosol. Here, the medium section 210 can be filled with at least 10% of a humectant that generates aerosols. Therefore, when the medium section 210 of the aerosol product 200 is heated by the second heater 145, it generates a large amount of aerosol, allowing nicotine and other substances to be supplied to the user.

[0099] More preferably, the humectant that generates the aerosol is present in an amount of 15% to 30%, and the most ideal example is when 15% is filled into the medium portion 210.

[0100] Here, the humectant for aerosol generation, 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.

[0101] Furthermore, the medium portion 210 may contain nicotine. The nicotine may be naturally occurring nicotine or synthetic nicotine. For example, the nicotine may include free base nicotine, nicotine salt, or a combination thereof.

[0102] Nicotine salts may be formed by adding a suitable acid, including organic acids or inorganic acids, to nicotine.

[0103] The acid used for forming nicotine salts can be appropriately selected considering factors such as the rate of nicotine absorption into the bloodstream, heating temperature, flavor, and solubility.

[0104] For example, acids for the formation of nicotine salts include benzoic acid, lactic acid, salicylic acid, lauric acid, sorbic acid, levulinic acid, pyruvic acid, formic acid, acetic acid, propionic acid, butyric acid, valeric acid, caproic acid, caprylic acid, capric acid, citric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, and phenylacetic acid. A single acid selected from the group consisting of (1) tartaric acid, succinic acid, fumaric acid, gluconic acid, saccharic acid, malonic acid, and malic acid, or a mixture of two or more acids selected from the aforementioned group, may be used, but is not limited to this.

[0105] On the other hand, it is preferable that the medium portion 210 is formed to have a similar lateral length to the second heater 145, based on the cross-section of the second heater 145. That is, the lateral length of the medium portion 210 and the lateral length of the second heater 145 may be formed to be similar. Therefore, the medium portion 210 can receive and heat all the heat generated by the second heater 145.

[0106] The medium portion 210 can, for example, be manufactured in a cylindrical shape by folding a tobacco sheet in a wrinkled manner, and may be formed by joining together multiple tobacco slits with channels formed therein. The medium portion 210 may also be wrapped in a heat-conducting material. Here, the heat-conducting material may be metal foil, aluminum, or a similar substance.

[0107] The cooling unit 220 is adjacent to the medium unit 210 and lowers the temperature of the substance generated by the medium unit 210 so that the user can inhale it. In other words, when the user applies suction force, the substance generated in the medium unit 210 can pass through the cooling unit 220 and be transmitted to the user.

[0108] As described above, when the aerosol generator 100 of the present invention operates in single mode, the aerosol product 200 is heated to a second temperature, which is even higher than the existing temperature, so discomfort may be transmitted to the user. The cooling unit 220 may be formed to have an air dilution ratio of about 10% or more. Preferably, it can have an air dilution ratio of about 15% to 30%, and it is preferable that it is formed to have an air dilution ratio of 20% or more.

[0109] The cooling section 220 may be formed in a hollow shape. The cooling section 220 cools the substance that moves through the cooling section 220 and is transmitted to the user, and may be a hollow cylindrical branch tube. The cooling section 220 may be made of a polymer or a biodegradable polymer.

[0110] Furthermore, the cooling section 220 may have multiple perforated holes 230 formed therein. As a result, outside air may be drawn into the cooling section 220 through the perforated holes 230. Therefore, substances moving through the cooling section 220 can be diluted and cooled by the air that flows in through the perforated holes 230.

[0111] The medium section 210 and the cooling section 220 can be fixed in a form that is wrapped by an external wrapper 240.

[0112] On the other hand, although no separate instruction number is assigned, a filter unit is positioned after the cooling unit 220 to filter out harmful substances, and at the same time, it can be held in the user's mouth and secured.

[0113] The following describes variations of aerosol products in an aerosol generation system.

[0114] Figures 7 and 8 show modified versions of the aerosol product shown in Figure 6.

[0115] Referring to Figure 7, a modified example of the aerosol product is shown, in the aerosol product 200, the cooling section 220 may consist of a first cooling section 221 and a second cooling section 222. The first cooling section 221 and the second cooling section 222 are arranged in a continuous manner, so that the substance can pass through the first cooling section 221 and the second cooling section 222 and be transmitted to the user's mouth.

[0116] The first cooling section 221 may be a hollow filter segment. Therefore, as a substance moves through the hollow of the first cooling section 221, it can be cooled by the first cooling section 221. The second cooling section 222 may be formed with an empty space inside and perforated holes 230 formed along its outer edge. Therefore, a substance moving through the second cooling section 222 can be cooled by being diluted with air by the air drawn in through the perforated holes 230.

[0117] The first cooling section 221 and the second cooling section 222 may be wrapped and secured by an internal wrapper 250 and an external wrapper 240. Here, perforated holes 230 may be formed in a portion of the internal wrapper 250 corresponding to the second cooling section 222 and in a portion of the external wrapper 240 corresponding to the internal wrapper 250.

[0118] Thus, the aerosol product 200 of the present invention can be efficiently cooled via the first cooling section 221 and the second cooling section 222.

[0119] Referring to Figure 8, another variation of the aerosol product 200 is shown, where the cooling section 220 of the aerosol product 200 may include a first segment 225 and a second segment 226. The first segment 225 and the second segment 226 may be cooling segments or may be formed into corresponding shapes.

[0120] For example, the first segment 225 may be formed in a hollow cylindrical shape, and the second segment 226 may be formed in a shape similar to the first segment 225. The first segment 225 and the second segment 226 are positioned side by side and adjacent to each other, and can be wrapped and secured by the internal wrapper 250.

[0121] Therefore, the substance can move through the hollow space between the first segment 225 and the second segment 226, thereby allowing it to be cooled.

[0122] Furthermore, multiple perforations 230 may be formed in the first segment 225 and the second segment 226. The perforations 230 do not need to be closed by the internal wrapper 250, and multiple perforations may also be formed in the external wrapper 240 that encloses the internal wrapper 250.

[0123] Therefore, when the user applies suction force, external air may pass through the perforated hole 230, through the first segment 225 and the second segment 226, and be drawn into the hollow space, thereby diluting and cooling the substance with air.

[0124] The following describes an aerosol generation system according to a second embodiment of the present invention.

[0125] Figure 9 shows an operational diagram of the aerosol generation system according to the second embodiment of the present invention.

[0126] Referring to Figure 9, the aerosol generation system according to the second embodiment allows setting a target temperature for each type of aerosol product 200 in the aerosol generation device 100. As mentioned above, the aerosol generation device 100 may include a detection sensor unit 170, and as mentioned above, its operation can distinguish and recognize the type of aerosol product 200.

[0127] The control unit 160 may have pre-stored target temperatures for different aerosol product 200. Therefore, when the aerosol generator 100 operates in single mode, the second heater 145 can operate at different temperatures. Here, "different temperature" does not mean either the first or second temperature, but rather a specific temperature within the second temperature range (e.g., 220 degrees). This is because it can vary depending on the amount of humectant packed in the medium section 210 and the degree to which the cooling section 220 can cool.

[0128] As an example, let's assume that aerosol product A 200 has a medium section 210 filled with 20% humectant and a cooling section 220 with an air dilution ratio of 10%, and aerosol product B 200 has a medium section 210 filled with 20% humectant and a cooling section 220 with an air dilution ratio of 20%. Let's also assume that aerosol product 200 operates in single mode. When aerosol product A 200 is placed in the inlet hole 150 of the aerosol generator 100, the control unit 160 can apply a control signal to set the second heater 145 to 200 degrees, and when aerosol product B 200 is placed in the inlet hole 150 of the aerosol generator 100, a control signal can be applied to set it to 220 degrees.

[0129] In other words, in the case of the aerosol generation system according to the second embodiment, the second heater 145 applies different temperatures depending on the aerosol product 200, so that a variety of good flavors can be provided to the user.

[0130] Although the present invention has been illustrated and described with respect to specific embodiments, it will be obvious to those of ordinary skill in the art that the present invention can be improved and modified in various ways without departing from the technical spirit of the invention as provided by the following claims.
