Description

Technical Field

[0001] The present invention relates to an atomizer and an aerosol generating device including the same. More specifically, the present invention relates to an atomizer that stably accommodates an aerosol generating substance.

Background Art

[0002] Recently, there has been an increasing demand for alternative methods to overcome the disadvantages of conventional cigarettes. For example, there has been an increasing demand for a system that generates an aerosol by heating a cigarette or an aerosol generating substance using an aerosol generating device, rather than a method of generating an aerosol by burning a cigarette. Accordingly, research on heat-type aerosol generating devices has been actively conducted.

[0003] An aerosol generating device that generates an aerosol by heating a liquid aerosol generating substance may include an atomizer that holds the liquid aerosol generating substance. The atomizer may be formed integrally with the main body of the aerosol generating device or may be detachably coupled thereto.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The atomizer is required to have chemical structural stability for storing the aerosol generating substance for a long period of time. If the atomizer is deformed by external temperature and / or light conditions or reacts with the aerosol generating substance during the storage period of the aerosol generating substance, it will have an adverse effect on the quality of the aerosol generating substance.

[0027] The terminology used in the embodiments is selected as widely used and general terms as possible, taking into account the function of the present invention, although this may vary depending on the intent of the articulators in the field, case law, the emergence of new technologies, etc. In certain cases, the applicant may have arbitrarily selected terms, in which case their meaning will be described in detail in the description of the invention. Therefore, the terms used in the present invention are not merely names of terms, but must be defined based on the meaning of the term and the overall content of the present invention.

[0028] Throughout the specification, when a part "includes" a component, it means, unless otherwise specified, that it does not exclude other components, but rather that it may include other components. Furthermore, terms such as "...part" and "...module" used in the specification mean a unit that processes at least one function or operation, which is embodied by hardware or software, or by a combination of hardware and software.

[0029] As used herein, when an expression such as “at least one of the following” precedes a set of elements, it modifies the entire set of elements, not each of the elements themselves. For example, the expression “at least one of a, b, and c” must be interpreted as including a, b, c, or a and b, a and c, b and c, or a, b, and c.

[0030] Furthermore, while terms including ordinal numbers, such as "first" or "second," as used herein may be used to describe a variety of components, such components are not limited by such terms. The terms are simply used to distinguish one component from another.

[0031] Furthermore, the size and proportions of some components in the drawings were somewhat exaggerated. Also, components shown in one drawing were not shown in other drawings.

[0032] Furthermore, throughout the specification, the "longitudinal direction" of a component refers to the direction in which the component extends along one axis of the component, where the one axis of the component means the direction in which the component extends further than other axes that intersect the one axis. For example, the longitudinal direction of a core means the direction parallel to the direction in which the core extends as shown in Figure 2.

[0033] Throughout the specification, "aerosol generating apparatus" is defined as an apparatus 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.

[0034] Throughout the specification, "aerosol product" means an article used for smoking. For example, an aerosol product can be a combustible cigarette used by being ignited and burned, or a heated cigarette used by being heated by an aerosol generating device.

[0035] Throughout this specification, "puff" means the user's inhalation. Inhalation means the user drawing an aerosol into their oral cavity, nasal cavity, or lungs through their mouth or nose.

[0036] Throughout the specification, “Embodiments” are arbitrary classifications that facilitate the explanation of the invention, and each embodiment does not need to be mutually exclusive. For example, a configuration disclosed in one embodiment may be applied to and / or embodied in other embodiments and may be modified, applied to and / or embodied within the limits that do not depart from the scope of the invention.

[0037] Furthermore, the terminology used in this invention is for illustrative purposes only and does not limit these embodiments. In this invention, the singular form includes the plural form unless otherwise specified.

[0038] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings, so that they can be easily implemented by a person with ordinary skill in the art to which the present invention pertains. However, the present invention can be embodied in various different forms and is not limited to the embodiments described herein.

[0039] An aerosol generating apparatus according to one embodiment will be described below with reference to the drawings.

[0040] Figure 1 is a front view of an aerosol generator to which a vaporizer is coupled according to one embodiment.

[0041] Referring to Figure 1, a vaporizer 1 and a main body 2 according to one embodiment can be coupled and operate as an aerosol generator 100. For example, the vaporizer 1 may be coupled to one region of the main body 2. The coupling direction of the vaporizer 1 is not limited to the illustrated example, and the vaporizer 1 may be coupled to the main body 2 along the longitudinal direction of the aerosol generator 100.

[0042] In one embodiment, the aerosol generator 100 may include a processor (not shown) and a battery (not shown). The battery and processor may be electrically connected to the vaporizer 1. For example, the battery and processor can supply and control power to the vaporizer 1. This allows the aerosol generator 100 to generate aerosols by heating liquid or gel-like aerosol-generating material stored in the vaporizer 1.

[0043] In other embodiments, the aerosol generator 100 may further include a housing (not shown) containing a space (not shown) for containing aerosol products and a separate heater (not shown) for heating the aerosol products contained in the housing.

[0044] For example, the space containing the aerosol product and the heater may be located in the main body 2. A vaporizer 1 may be coupled to one area of ​​the main body 2, and the aerosol product may be inserted into another area of ​​the main body 2.

[0045] The aerosol generator 100 may not only generate aerosols using the vaporizer 1, but may also generate aerosols using the inserted aerosol product. This allows for the realization of a hybrid aerosol generator 100.

[0046] In yet another embodiment, the aerosol generator 100 may further include a removable cap (not shown) for protecting at least a portion of the main body 2 and a vaporizer 1 coupled to the main body 2. The removable cap may be coupled to one end of the aerosol generator 100 where the vaporizer 1 and the main body 2 are coupled. For example, the removable cap may be separated from / coupled to the main body 2 when replacing the vaporizer 1.

[0047] Figure 2 is an exploded perspective view of the steam maker shown in Figure 1, and Figure 3 is a bottom perspective view of the steam maker shown in Figure 1.

[0048] Referring to Figures 2 and 3, a vaporizer 1 according to one embodiment may include a storage section 10, a sealing section 20, a wick 30, a heating element 40, a housing section 50, and a cover 60. The storage section 10, the sealing section 20, the wick 30, the heating element 40, the housing section 50, and the cover 60 may be coupled in the z-axis direction as shown in the figures.

[0049] For example, after the heating element 40 and the wick 30 are housed in the housing section 50, the housing section 50 is inserted inside the cover 60, and the sealing section 20 can come into contact with or be coupled to the housing section 50. This allows the sealing section 20 and the housing section 50 to be located inside the cover 60. Finally, the storage section 10 and the cover 60 are coupled to assemble the vaporizer 1. However, the assembly sequence and coupling method of the vaporizer 1 are not limited to the examples described above.

[0050] The storage unit 10 can store aerosol-generating material. Liquid or gel-like aerosol-generating material can be stored in the storage unit 10. The aerosol-generating material stored in the storage unit 10 is transferred to and absorbed by the core 30, and the aerosol-generating material absorbed by the core 30 can be converted into an aerosol by being heated by the heating element 40.

[0051] At least one area of ​​the storage section 10 may be opened. For example, the bottom surface or at least a portion of the bottom surface of the storage section 10 may be opened so that aerosol-generating material can easily move to the outside of the storage section 10 due to the action of gravity.

[0052] According to one embodiment, the storage section 10 may be coupled with a sealing section 20 that prevents leakage of aerosol-generating material. By coupling the sealing section 20 to at least one area of ​​the storage section 10 (for example, an open surface of the storage section 10), a storage space 12 for containing aerosol-generating material can be formed together with the storage section 10.

[0053] The sealing portion 20 may be made of a material that tightly bonds with a portion of the storage portion 10. For example, the sealing portion 20 may be made of an elastic material such as rubber or silicone, but is not limited to these.

[0054] The sealing portion 20 tightly connects to a region of the storage portion 10 where the internal storage space 12 of the storage portion 10 is exposed, thereby preventing the leakage of aerosol-generating material. Here, "tightly connects" means that the sealing portion 20 is firmly connected to the storage portion 10 so that no gaps are created between the storage portion 10 and other components (for example, between the storage portion 10 and the containment portion 50) through which the aerosol-generating material can leak.

[0055] On the other hand, the sealing portion 20 may be manufactured to be joined to / separated from the storage portion 10, or it may be manufactured integrally with the storage portion 10.

[0056] With the storage section 10 and the sealing section 20 joined together, the sealing section 20 may include at least one opening 22 so that the aerosol-generating material stored in the storage section 10 can move to the outside of the storage section 10.

[0057] For example, the inner surface of the storage space 12 of the storage unit 10 is exposed to the outside through an open area, but a sealing part 20 including an opening 22 can be connected to a region of the storage unit 10. This allows the aerosol-generating material stored in the storage space 12 of the storage unit 10 to move to the outside of the storage unit 10 through the opening 22 formed in the sealing part 20, preventing the aerosol-generating material stored in the storage unit 10 from leaking out to the outside of the storage unit 10 through any gaps other than the opening 22.

[0058] The core 30 can absorb aerosol-generating substances supplied from the storage unit 10 by receiving the aerosol-generating substances through this transfer. The core 30 may have an elongated shape. For example, the core 30 may be a columnar shape extended in one direction. Specifically, the core 30 may be a polygonal columnar shape such as a cylindrical, rectangular prism, or triangular prism, but is not limited to the examples described above, and the core 30 may have a substantially rod-like, needle-like, or planar shape.

[0059] The core 30 can absorb aerosol-generating material supplied from one part to the storage part 10. For example, aerosol-generating material absorbed by one part of the core 30 can move to other parts of the core 30 by capillary action. The core 30 may contain a variety of materials. For example, the core 30 may contain at least one of cotton, ceramic, and glass fiber.

[0060] In one embodiment, the core 30 may include a first end 31, a second end 33, and a central part 32 between the first end 31 and the second end 33. The aerosol-generating substance supplied from the storage unit 10 may be absorbed into the core 30 through the first end 31 and the second end 33. The aerosol-generating substance absorbed into the core 30 may move to the central part 32 of the core 30.

[0061] The heating element 40 can generate an aerosol by heating the aerosol-generating substance absorbed by the core 30. The heating element 40 may be positioned adjacent to the core 30. The heating element 40 can generate an aerosol by heating the liquid aerosol-generating substance transferred to the central part 32 of the core 30.

[0062] For example, the heating element 40 is a coil-shaped resistive heater wound around the outer surface of the central part 32 of the core 30. Another example is a resistive heater printed on the central part 32 of the core 30. The heating element 40 is not limited to the examples given above, and the heating element 40 can also be a porous element formed integrally with the core 30.

[0063] The housing section 50 may include housing spaces 51, 52, and 53 for housing the core 30 and the heating element 40. For example, the housing section 50 may include at least one support groove 52 for supporting at least a portion of the core 30, at least one storage groove 51 for temporarily storing the aerosol-generating material so as to transfer it to the core 30, and a central space 53 for housing the central part 32 of the core 30.

[0064] The housing section 50, together with at least a portion of the sealing section 20, forms a cavity, and at least a portion of the core 30 may be located in the cavity. The cavity is the space surrounded by the housing section 50 and the sealing section 20, and means the space in which at least a portion of the core 30 is located. For example, the central part 32 of the core 30, around which the heating element 40 is wound, may be located in the cavity, and an aerosol may be generated from the cavity.

[0065] Meanwhile, outside air flows into the interior of the containment section 50 through an inlet 56 which is included in at least a portion of the containment section 50, and aerosols generated from the cavity can be discharged to the outside of the containment section 50 through an outlet 57 which is included in at least a portion of the containment section 50.

[0066] The cover 60 can be coupled with the housing 50 and the sealing 20. The cover 60 may include an inner space 62 in which the housing 50 and the sealing 20 are arranged. For example, the cover 60 may include an inner space 62 inside which the shape corresponds to the outer shapes of the housing 50 and the sealing 20. The housing 50 and the sealing 20, arranged in the inner space 62 of the cover 60, can not only be appropriately aligned with each other but also be covered by the cover 60 and protected from external impacts.

[0067] The cover 60 may include a connecting passage 64 that guides the aerosol discharged from the outlet 57 of the containment section 50 to the outside of the vaporizer 1. For example, with the containment section 50 positioned in the inner space 62 of the cover 60, the connecting passage 64 may be located at a position corresponding to the outlet 57, and the outlet 57 may be connected to the connecting passage 64. The aerosol discharged to the outside of the containment section 50 through the outlet 57 can move to the outside of the vaporizer 1 along the connecting passage 64.

[0068] For example, the connecting passage 64 may be connected to the main body 2 of the aerosol generator 100. Aerosols discharged to the outside of the containment section 50 through the outlet 57 may move to the main body 2 of the aerosol generator 100 through the connecting passage 64 and be discharged to the outside of the aerosol generator 100 along the airflow passage formed in the main body 2.

[0069] The cover 60 may include connecting terminals 66 that electrically connect the vaporizer 1 and the main body 2. For example, the connecting terminals 66 can be connected to the heating element 40 and mediate the connection between the battery and processor contained in the main body 2 and the heating element 40. This allows the heating element 40 to be powered and controlled by the battery and processor.

[0070] The storage section 10 may contain a plastic containing a polymer resin and a stability-enhancing substance. For example, the storage section 10 is made of a plastic containing a polymer resin and a stability-enhancing substance. The polymer resin refers to the main material contained in the plastic and can determine the basic properties of the plastic.

[0071] For example, the polymer resin includes, but is not limited to, one or more polymer resins selected from the group consisting of PCTG (Polycyclohexylenedimethylene terephthalate glycol), PETG (Polyethylene glycol-co-1,4-cyclohexanedimethanol terephthalate), SAN (Styrene-acrylonitrile), PMMA (Poly(methyl methacrylate)), and PS (Polystyrene). Here, PS may include GPPS (General purpose polystyrene) and / or HIPS (High impact polystyrene). The polymer resin is transparent so that the remaining amount of aerosol-generating material stored in the storage section 10 can be checked. It may also have thermal stability to withstand the heat generated when the aerosol-generating material is heated and robustness to withstand external impacts.

[0072] The stability-enhancing substance is mixed with the polymer resin to improve the chemical structural stability of the plastic. The storage section 10 requires chemical structural stability to store aerosol-generating substances for a long period of time. If the storage section 10 is deformed by external temperature and / or light conditions during the storage period, or reacts with the stored aerosol-generating substances, it will adversely affect the quality of the aerosol-generating substances. By mixing the stability-enhancing substance with the polymer resin to improve the chemical structural stability of the plastic, it is possible to prevent the quality of the aerosol-generating substances from deteriorating over time.

[0073] For example, stability-enhancing substances may include polybutadiene. Polybutadiene can be mixed with the aforementioned types of polymer resins to improve the stability of the polymer resin's chemical structure, thereby preventing deformation of the chemical structure caused by external temperature and / or light conditions. In addition, the reaction between the polymer resin and aerosol-generating substances is suppressed, and the quality of the aerosol-generating substances can be maintained during storage.

[0074] Polybutadiene may have 1,2-structures in approximately 70% or more of its monomer units. When a polymeric resin contains polybutadiene in which approximately 70% or more of its monomer units have 1,2-structures, stable storage is possible regardless of the properties of the fragrance contained in the aerosol-generating substance (e.g., polarity, volatility, etc.), in addition to the effects described above. For example, polybutadiene may have 1,2-structures in approximately 80% or more of its monomer units, or approximately 90% or more, have 1,2-structures, but is not limited to this.

[0075] The stability-enhancing substance is present in an amount of approximately 0.1% to 5% by weight of the total weight of the plastic. Within this range of approximately 0.1% to 5% by weight, the stability-enhancing substance improves the chemical structure stability of the plastic while simultaneously providing transparency. If the stability-enhancing substance is present in an amount of less than approximately 0.1% by weight of the total weight of the plastic, the effect of improving the plastic's stability is insufficient. If the stability-enhancing substance exceeds approximately 5% by weight of the total weight of the plastic, the transparency of the plastic is insufficient. Furthermore, the stability-enhancing substance is present in an amount of approximately 0.5% to 3% by weight, or approximately 0.7% to 2% by weight, of the total weight of the plastic.

[0076] The plastic may further contain biomass. The biomass contained in the plastic improves its decomposability during the disposal process of the vaporizer 1 after use. For example, the biomass is lignocellulose biomass, but is not limited to this.

[0077] Plastics contain approximately 0.01% to 5% by weight of biomass based on the total weight of the plastic. Within this range of approximately 0.01% to 5% by weight, the biomass does not impair the stability of the plastic's chemical structure while simultaneously improving its decomposition during disposal. If the biomass content is less than approximately 0.01% by weight based on the total weight of the plastic, the decomposition during disposal is insufficient. If the biomass content exceeds approximately 5% by weight based on the total weight of the plastic, the stability of the plastic's chemical structure is impaired. Furthermore, the biomass content can range from approximately 0.1% to 3% by weight, or from approximately 0.5% to 1% by weight based on the total weight of the plastic.

[0078] The aerosol-generating substance may further contain fragrances. The plastic contained in the storage section 10 of the vaporizer 1 according to this embodiment allows for stable storage regardless of the properties of the fragrance (e.g., polarity, volatility, etc.) based on its excellent stability.

[0079] The cover 60 may contain the same plastic as the storage section 10. When the cover 60 contains the same material as the storage section 10, the bonding strength between the cover 60 and the storage section 10 is improved. For example, the plastic may contain PCTG as a polymer resin and polybutadiene as a stability-enhancing substance at a concentration of approximately 1% by weight relative to the total weight of the polymer resin, and the cover 60 and the storage section 10 may be made of the same plastic. However, the plastic contained in the cover 60 and the storage section 10 is not limited to this, and the aforementioned polymer resins and stability-enhancing substances may be applied without restriction.

[0080] Furthermore, components of the vaporizer 1 other than the cover 60 and the storage section 10 may also include the same plastic. For example, the storage section 10, cover 60, sealing section 20, and housing section 50 may, but are not limited to, include the same plastic.

[0081] Experimental Example 1: Chemical Structural Stability Analysis Plastics were manufactured using different types of polymer resins (PCTG, SAN, PMMA, GPPS), and varying content of polymer resins and stability-enhancing substances. Polybutadiene, in which more than 90% of the monomer units have a 1,2-structure, was used as the stability-enhancing substance.

[0082] To confirm the chemical structural stability of the manufactured plastic, the amount of gas collected was analyzed using thermal desorption gas chromatography. The thermal desorption pretreatment was carried out at a heating temperature of 200°C, and the generated gas was collected for 60 minutes. If the amount of collected gas was above the standard value, it was indicated as "O"; if it exceeded the standard value, it was indicated as "X". The results are shown in Table 1 below.

[0083] Experimental Example 2: Stability Analysis of Aerosol-Generating Substances A vaporizer was manufactured using the plastic produced in Experimental Example 1. An aerosol-generating substance containing 100% by weight of glycerin was stored in the storage compartment of the vaporizer.

[0084] To analyze the stability of glycerin stored in a vaporizer, the vaporizer was left at room temperature for four weeks, and then the viscosity of the glycerin was measured. If the difference between the measured viscosity and the initial viscosity was greater than or equal to the standard value, it was indicated as "O"; if it exceeded the standard value, it was indicated as "X". The results are shown in Table 1 below. [Table 1]

[0085] Referring to Table 1, it was confirmed that plastics containing stability-enhancing substances exhibit improved structural stability compared to plastics without such substances. Furthermore, it was confirmed that plastics containing 1% by weight of the stability-enhancing substance showed improved stability of glycerin stored in a vaporizer compared to plastics without the substance. On the other hand, in the case of plastics containing 5% by weight of the stability-enhancing substance, no improvement in the stability of glycerin stored in a vaporizer was observed, similar to plastics without the substance. However, it is expected that increasing the content of the stability-enhancing substance will enhance the inherent properties of the stability-enhancing substance.

[0086] Experiment Example 3: Stability Analysis of Fragrances A vaporizer was manufactured using plastic containing 99% by weight of PCTG and 1% by weight of polybutadiene, and glycerin containing fragrance was stored in the vaporizer's storage compartment. For the polybutadiene, two types were used: one in which more than 70% of the monomer units have a 1,2-structure, and another in which less than 70% of the monomer units have a 1,2-structure. To analyze the stability of the fragrance stored in the vaporizer, the vaporizer was left at room temperature for four weeks, after which a sensory evaluation was conducted. The sensory evaluation involved 15 men and women aged 20-45 years. After inhaling the aerosol generated by the vaporizer, participants rated their preference for the fragrance of the inhaled aerosol on a scale of 1 to 5. Table 2 below shows the average sensory evaluation scores. [Table 2]

[0087] Referring to Table 2, it was confirmed that when 70% or more of the monomer units of polybutadiene have a 1,2-structure, it exhibits higher palatability compared to when less than 70% of the monomer units have a 1,2-structure. This is presumably because the amount of volatile fragrance lost was relatively small. This confirms that when polybutadiene plastics contain 70% or more monomer units with a 1,2-structure, the fragrance can be stored more stably.

[0088] The following describes aerosol generators including vaporizers according to other embodiments, and aerosol products used in conjunction with aerosol generators.

[0089] Figures 4 and 5 are diagrams showing examples of aerosol products being inserted into an aerosol generator.

[0090] Referring to Figures 4 and 5, the aerosol generator 100 comprises a battery 110, a control unit 120, a heater 130, and a vaporizer 140. The aerosol product 200 is inserted into the internal space of the aerosol generator 100.

[0091] Although the aerosol generator 100 shown in Figures 4 and 5 includes a vaporizer, the embodiment is not limited by such a method of implementing the aerosol generator, and the vaporizer may be omitted in the aerosol generator 100. When the vaporizer is omitted in the aerosol generator 100, the aerosol product 200 contains an aerosol-generating substance, and when the aerosol product 200 is heated by the heater 130, the aerosol product 200 generates an aerosol.

[0092] The aerosol generator 100 shown in Figures 4 and 5 shows the components according to this embodiment. Therefore, those skilled in the art will understand that, in addition to the components shown in Figures 4 and 5, other general-purpose components may be further included in the aerosol generator 100.

[0093] Furthermore, although Figures 4 and 5 show that the aerosol generator 100 includes a heater 130, the heater 130 may be omitted if necessary.

[0094] Figure 4 shows that the battery 110, control unit 120, vaporizer 140, and heater 130 are arranged in a line. Figure 5 shows that the vaporizer 140 and heater 130 are arranged in parallel. However, the internal structure of the aerosol generator 100 is not limited to that shown in Figure 4 or Figure 5. In other words, the arrangement of the battery 110, control unit 120, vaporizer 140, and heater 130 may be changed depending on the design of the aerosol generator 100.

[0095] When the aerosol product 200 is inserted into the aerosol generator 100, the aerosol generator 100 activates the vaporizer 140 to generate an aerosol from the vaporizer 140. The aerosol generated by the vaporizer 140 passes through the aerosol product 200 and is delivered to the user. A more detailed explanation of the vaporizer 140 is provided below.

[0096] The battery 110 supplies the power used when the aerosol generator 100 operates. For example, the battery 110 supplies power to heat the heater 130 or the vaporizer 140, and supplies the power necessary for the control unit 120 to operate. The battery 110 also supplies the power necessary for the operation of the display, sensors, motors, etc., provided in the aerosol generator 100.

[0097] The control unit 120 controls the overall operation of the aerosol generator 100. Specifically, the control unit 120 controls the operation of not only the battery 110, heater 130, and vaporizer 140, but also other components of the aerosol generator 100. The control unit 120 can also check the status of each component of the aerosol generator 100 and determine whether the aerosol generator 100 is operational.

[0098] The control unit 120 comprises at least one processor. The processor may be embodied as an array of numerous logic gates, or as a combination of a general-purpose microprocessor and memory in which a program executed by this microprocessor is stored. Those skilled in the art will understand that it may also be embodied as other forms of hardware.

[0099] The heater 130 is heated by power supplied from the battery 110. For example, when the aerosol product 200 is inserted into the aerosol generator 100, the heater 130 is located outside the aerosol product 200. Therefore, the heated heater 130 raises the temperature of the aerosol-generating substance inside the aerosol product 200.

[0100] The heater 130 may be an electrical resistance heater. For example, the heater 130 may have a conductive track, and current may flow through the conductive track to heat the heater 130. However, the heater 130 is not limited to the above example and can be used without restriction as long as it can be heated to a desired temperature. Here, the desired temperature may be preset in the aerosol generator 100 or set to a desired temperature by the user.

[0101] On the other hand, as another example, the heater 130 may be an induction heater. Specifically, the heater 130 is equipped with an electrically conductive coil for heating the aerosol product by induction heating, and the aerosol product is equipped with a susceptor that is heated by the induction heater.

[0102] Figures 4 and 5 show the heater 130 positioned outside the aerosol product 200, but are not limited thereto. For example, the heater 130 may include tubular heating elements, plate heating elements, needle-shaped heating elements, or rod-shaped heating elements, and depending on the shape of the heating elements, it may heat the inside or outside of the aerosol product 200.

[0103] Furthermore, the aerosol generator 100 may be equipped with multiple heaters 130. In this case, the multiple heaters 130 may be arranged so as to be inserted inside the aerosol product 200, or they may be arranged outside the aerosol product 200. Alternatively, some of the multiple heaters 130 may be arranged so as to be inserted inside the aerosol product 200, and the rest may be arranged outside the aerosol product 200. Also, the shape of the heaters 130 is not limited to the shapes shown in Figures 4 and 5, and they may be manufactured in a variety of shapes.

[0104] The vaporizer 140 heats the liquid composition to generate an aerosol, which is then delivered to the user through the aerosol product 200. In other words, the aerosol generated by the vaporizer 140 travels along the airflow passage of the aerosol generator 100, which is configured so that the aerosol generated by the vaporizer 140 is delivered to the user through the aerosol product 200.

[0105] For example, the vaporizer 140 includes a liquid storage unit, a liquid transfer means, and a heating element, but is not limited to these. For instance, the liquid storage unit, liquid transfer means, and heating element may be provided in the aerosol generator 100 as independent modules.

[0106] The liquid storage unit stores a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing substance that includes volatile tobacco flavor components, or a liquid containing a non-tobacco substance. The liquid storage unit may be manufactured to be detachable from the vaporizer 140, or it may be manufactured integrally with the vaporizer 140.

[0107] For example, a liquid composition may include water, solvent, ethanol, plant extracts, fragrances, flavoring agents, or vitamin mixtures. Fragrances may include, but are not limited to, menthol, peppermint, spearmint oil, and various fruit fragrance components. Flavoring agents may include components that provide users with a variety of flavors or aromas. Vitamin mixtures may also be mixtures of at least one of vitamins A, B, C, and E, but are not limited to these. Furthermore, a liquid composition may include aerosol-forming agents such as glycerin and propylene glycol.

[0108] The liquid transfer means transfers the liquid composition of the liquid storage section to the heating element. For example, the liquid transfer means may be, but is not limited to, a wick made of cotton fibers, ceramic fibers, glass fibers, or porous ceramics.

[0109] The heating element is an element for heating the liquid composition that is transmitted by the liquid transmission means. For example, the heating element may be a metal heating wire, a metal heating plate, a ceramic heater, etc., but is not limited to these. The heating element may also be composed of a conductive filament such as a nichrome wire, and may be arranged in a structure that is wound around the liquid transmission means. The heating element is heated by the supply of electric current, and heat is transferred to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, an aerosol is generated.

[0110] For example, the steam generator 140 is called a cartomizer or atomizer, but is not limited to these terms.

[0111] On the other hand, the aerosol generator 100 may further include general-purpose components in addition to the battery 110, control unit 120, heater 130, and vaporizer 140. For example, the aerosol generator 100 may include a display capable of outputting visual information and / or a motor for outputting tactile information. The aerosol generator 100 may also include at least one sensor (such as a puff sensor, temperature sensor, or aerosol product insertion detection sensor). Furthermore, the aerosol generator 100 may be constructed in such a way that outside air flows in or internal gas flows out even when the aerosol product 200 is inserted.

[0112] Although not shown in Figures 4 and 5, the aerosol generator 100 may be configured with a separate cradle. For example, the cradle may be used to charge the battery 110 of the aerosol generator 100. Alternatively, the heater 130 may be heated while the cradle and the aerosol generator 100 are coupled together.

[0113] The aerosol product 200 is similar to a typical combustible cigarette. For example, the aerosol product 200 is divided into a first part containing an aerosol-generating substance and a second part containing a filter or the like. Alternatively, the second part of the aerosol product 200 may also contain an aerosol-generating substance. For example, an aerosol-generating substance made in the form of granules or capsules may be inserted into the second part.

[0114] The entire first part is inserted into the aerosol generator 100, while the second part is exposed to the outside. Alternatively, only a portion of the first part may be inserted into the aerosol generator 100, or parts of both the first and second parts may be inserted. The user inhales the aerosol with the second part in their mouth. At this time, the aerosol is generated as outside air passes through the first part, and the generated aerosol is transmitted to the user's mouth by passing through the second part.

[0115] As an example, outside air flows in through at least one air passage formed in the aerosol generator 100. For example, the opening and closing of the air passage formed in the aerosol generator 100 and / or the size of the air passage can be adjusted by the user. This allows the amount of atomization, the smoking sensation, etc., to be adjusted by the user. As another example, outside air may also flow into the aerosol product 200 through at least one pore formed on the surface of the aerosol product 200.

[0116] Examples of aerosol product 200 will be described below with reference to Figures 6 and 7.

[0117] Figures 6 and 7 are diagrams showing examples of aerosol products.

[0118] Referring to Figure 6, the aerosol product 200 comprises a tobacco rod 210 and a filter rod 220. Referring to Figures 4 and 5, the first part described above comprises the tobacco rod 210, and the second part comprises the filter rod 220.

[0119] Figure 6 shows the filter rod 220 as a single segment, but it is not limited to this. In other words, the filter rod 220 may consist of multiple segments. For example, the filter rod 220 may have a first segment for cooling the aerosol and a second segment for filtering out predetermined components contained in the aerosol. Alternatively, the filter rod 220 may further have at least one additional segment performing other functions.

[0120] The aerosol product 200 is packaged by at least one trumpet 240. The trumpet 240 has at least one hole through which outside air enters or internal gases exit. As an example, the aerosol product 200 is packaged by one trumpet 240. As another example, the aerosol product 200 may be packaged in layers by two or more trumpets 240. For example, the tobacco rod 210 may be packaged by a first trumpet 241, and the filter rod 220 may be packaged by trumpets 242, 243, and 244. The entire aerosol product 200 may then be repackaged by a single trumpet 245. If the filter rod 220 consists of multiple segments, each segment may be packaged by trumpets 242, 243, and 244.

[0121] The tobacco rod 210 contains an aerosol-generating substance. For example, the aerosol-generating substance includes, but is not limited to, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. The tobacco rod 210 may also contain other additives such as flavoring agents, humectants, and / or organic acids. Furthermore, a flavoring liquid such as menthol or a humectant may be added to the tobacco rod 210 by spraying it.

[0122] The tobacco rod 210 can be manufactured in various forms. For example, the tobacco rod 210 can be manufactured in sheet form or strand form. Alternatively, the tobacco rod 210 may be made from shredded tobacco obtained by finely cutting tobacco sheets. Furthermore, the tobacco rod 210 may be surrounded by a heat conductive material. For example, the heat conductive material may be a metal foil such as aluminum foil, but is not limited to this. As an example, the heat conductive material surrounding the tobacco rod 210 can uniformly distribute the heat transferred to the tobacco rod 210, improving the thermal conductivity applied to the tobacco rod and thereby improving the tobacco flavor. The heat conductive material surrounding the tobacco rod 210 can also function as a susceptor heated by an induction heater. In this case, although not shown in the drawings, the tobacco rod 210 may further include a susceptor in addition to the heat conductive material surrounding its exterior.

[0123] The filter rod 220 may be a cellulose acetate filter. On the other hand, there are no restrictions on the shape of the filter rod 220. For example, the filter rod 220 may be a cylindrical rod, or a tubular rod containing a hollow inside. The filter rod 220 may also be a recessed rod. If the filter rod 220 is composed of multiple segments, at least one of the segments may be made in a different shape.

[0124] The filter rod 220 may be manufactured to generate flavor. For example, a flavoring liquid may be sprayed onto the filter rod 220, or a separate fiber coated with the flavoring liquid may be inserted inside the filter rod 220.

[0125] Furthermore, the filter rod 220 includes at least one capsule 230, where the capsule 230 generates flavor or aerosol. For example, the capsule 230 has a structure in which a liquid containing a flavor is enclosed in a film. The capsule 230 may, but is not limited to, a spherical or cylindrical shape.

[0126] If the filter rod 220 includes a segment for cooling the aerosol, the cooling segment is made of a polymer or a biodegradable polymer. For example, the cooling segment may be made solely of pure polylactic acid, but is not limited to this. Alternatively, the cooling segment may be made of a cellulose acetate filter with multiple pores. However, the cooling segment is not limited to the examples described above, and is open to any material that can perform the function of cooling the aerosol.

[0127] Referring to Figure 7, the aerosol product 300 further comprises a front plug 330. The front plug 330 is located on the tobacco rod 310 on one side opposite the filter rod 320. The front plug 330 prevents the tobacco rod 310 from detaching to the outside and prevents liquefied aerosol from flowing from the tobacco rod 310 into the aerosol generator (100 in Figures 4 and 5) during smoking.

[0128] The filter rod 320 comprises a first segment 321 and a second segment 322. Here, the first segment 321 corresponds to the first segment of the filter rod 220 in Figure 6, and the second segment 322 corresponds to the third segment of the filter rod 220 in Figure 6.

[0129] The diameter and overall length of the aerosol product 300 correspond to the diameter and overall length of the aerosol product 200 in Figure 6. For example, the length of the front plug 330 is approximately 7 mm, the length of the tobacco rod 310 is approximately 15 mm, the length of the first segment 321 is approximately 12 mm, and the length of the second segment 322 is approximately 14 mm, but are not limited to these.

[0130] The aerosol product 300 is packaged by at least one trumpet 350. The trumpet 350 has at least one hole through which outside air enters or internal gases exit. For example, the front plug 330 is packaged by a first trumpet 351, the tobacco rod 310 is packaged by a second trumpet 352, the first segment 321 is packaged by a third trumpet 353, and the second segment 322 is packaged by a fourth trumpet 354.

[0131] The entire aerosol product 300 may then be repackaged by the fifth wrapper 355. The fifth wrapper 355 may also have at least one perforation 360. For example, the perforation 360 may be formed in the region surrounding the tobacco rod 310, but is not limited to this. The perforation 360 serves to transfer the heat generated by the heater 130 shown in Figures 5 and 6 into the interior of the tobacco rod 310.

[0132] Furthermore, the second segment 322 may include at least one capsule 340, where the capsule 340 generates flavor or an aerosol. For example, the capsule 340 has a structure in which a liquid containing a flavor is enclosed in a film. The capsule 340 may be spherical or cylindrical, but is not limited to these.

[0133] Figure 8 is a block diagram of an aerosol generating apparatus according to another embodiment.

[0134] The aerosol generator 800 includes a control unit 810, a sensing unit 820, an output unit 830, a battery 840, a heater 850, a user input unit 860, a memory 870, and a communication unit 880.

The output unit 830 includes, but is not limited to, at least one of the display unit 832, the haptic unit 834, and the acoustic output unit 836. When the display unit 832 and the touchpad form a layered structure to constitute a touchscreen, the display unit 832 can be used as an input device in addition to an output device.

[0142] The display unit 832 can visually provide the user with information about the aerosol generator 800. For example, the information about the aerosol generator 800 can include various types of information such as the charge / discharge status of the battery 840 of the aerosol generator 800, the preheating status of the heater 850, the insertion / removal status of aerosol products, or a state in which the use of the aerosol generator 800 is restricted (e.g., detection of abnormal items), and the display unit 832 can output this information to the outside. The display unit 832 can be, for example, a liquid crystal display panel (LCD), an organic light-emitting display panel (OLED), or an LED light-emitting element.

[0143] The haptic unit 834 can convert electrical signals into mechanical or electrical stimuli, providing the user with tactile information about the aerosol generator 800. For example, the haptic unit 834 may include a motor, a piezoelectric element, or an electrical stimulator.

[0144] The acoustic output unit 836 can provide the user with auditory information about the aerosol generator 800. For example, the acoustic output unit 836 can convert electrical signals into acoustic signals and output them externally.

[0145] The battery 840 can supply power used to operate the aerosol generator 800. The battery 840 can supply power to heat the heater 850. The battery 840 can also supply power necessary for the operation of other components within the aerosol generator 800 (e.g., the sensing unit 820, the output unit 830, the user input unit 860, the memory 870, and the communication unit 880). The battery 840 may be a rechargeable battery or a disposable battery. For example, the battery 840 is a lithium polymer (LiPoly) battery, but is not limited to that.

[0146] The heater 850 is powered by the battery 840 and can heat the aerosol-generating material. Although not shown in Figure 8, the aerosol generator 800 may further include a power conversion circuit (e.g., a DC / DC converter) that converts the power from the battery 840 and supplies it to the heater 850. Furthermore, if the aerosol generator 800 generates aerosols by induction heating, the aerosol generator 800 may further include a DC / AC converter that converts the DC power supply of the battery 840 into AC power supply.

[0147] The control unit 810, sensing unit 820, output unit 830, user input unit 860, memory 870, and communication unit 880 can function by being powered by the battery 840. Although not shown in Figure 8, the system may further include power conversion circuits, such as an LDO (low dropout) circuit or a voltage regulator circuit, that convert the power from the battery 840 and supply it to each component.

[0148] In one embodiment, the heater 850 may be formed from any suitable electrical resistant material. Suitable electrical resistant materials include, but are not limited to, metals or metal alloys, such as titanium, zirconium, tantalum, platinum, nickel, cobalt, chromium, hafnium, niobium, molybdenum, tungsten, tin, gallium, manganese, iron, copper, stainless steel, and nichrome. The heater 850 may also be embodied by, but are not limited to, a metal heating wire, a metal heating plate on which conductive tracks are arranged, or a ceramic heating element.

[0149] In other embodiments, the heater 850 is also an induction heating heater. For example, the heater 850 may include a susceptor that generates heat through a magnetic field applied by a coil to heat the aerosol-generating material.

[0150] The user input unit 860 can receive information input from the user or output information to the user. For example, the user input unit 860 may include, but is not limited to, a key pad, a dome switch, a touch pad (contact-type capacitive type, pressure-type resistive type, infrared sensing type, surface ultrasonic conduction type, integral tension measurement type, piezoelectric effect type, etc.), a jog wheel, a jog switch, etc. Also, although not shown in Figure 8, the aerosol generator 800 may further include a connection interface such as a USB (universal serial bus) interface, and can connect to other external devices via a connection interface such as a USB interface to send and receive information or charge the battery 840.

[0151] Memory 870 is hardware that stores various data processed within the aerosol generator 800, and can store data processed by the control unit 810 and data being processed. Memory 870 includes at least one type of recording medium from among flash memory type, hard disk type, multimedia card micro type, card type memory (e.g., SD or XD memory), RAM (Random Access Memory), SRAM (Static Random Access Memory), ROM (Read-Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM (Programmable Read-Only Memory), magnetic memory, magnetic disk, and optical disk. Memory 870 can store data such as the operating time of the aerosol generator 800, the maximum number of puffs, the current number of puffs, at least one temperature profile, and data related to the user's smoking pattern.

[0152] The communication unit 880 includes at least one component for communication with other electronic devices. For example, the communication unit 880 includes a short-range communication unit 882 and a wireless communication unit 884.

[0153] The short-range wireless communication unit (882) includes, but is not limited to, a Bluetooth communication unit, a BLE (Bluetooth Low Energy) communication unit, a Near Field Communication unit, a WLAN (Wi-Fi) communication unit, a Zigbee communication unit, an infrared (IrDA: infrared Data Association) communication unit, a WFD (Wi-Fi Direct) communication unit, a UWB (ultra wideband) communication unit, an Ant+ communication unit, and others.

[0154] The wireless communication unit 884 includes, but is not limited to, a cellular network communication unit, an Internet communication unit, or a computer network (e.g., LAN or WAN) communication unit. The wireless communication unit 884 can also verify and authenticate the aerosol generator 800 within the communication network using subscriber information (e.g., International Mobile Subscriber Identifier (IMSI)).

[0155] The control unit 810 can control the overall operation of the aerosol generator 800. In one embodiment, the control unit 810 includes at least one processor. The processor may be embodied as an array of numerous logic gates, or as a combination of a general-purpose microprocessor and memory storing a program executable by the microprocessor. It will be understood by those ordinary skill in the art to which this embodiment belongs that it may also be embodied by other forms of hardware.

[0156] The control unit 810 can control the temperature of the heater 850 by controlling the supply of power from the battery 840 to the heater 850. For example, the control unit 810 can control the power supply by controlling the switching of a switching element between the battery 840 and the heater 850. As another example, the direct heating circuit can also control the power supply to the heater 850 by a control command from the control unit 810.

[0157] The control unit 810 can analyze the results sensed by the sensing unit 820 and control subsequent processing. For example, based on the results sensed by the sensing unit 820, the control unit 810 can control the power supplied to the heater 850 so that the heater 850 starts or stops operating. As another example, based on the results sensed by the sensing unit 820, the control unit 810 can control the amount of power supplied to the heater 850 and the power supply time so that the heater 850 is heated to a predetermined temperature or maintains an appropriate temperature.

[0158] The control unit 810 can control the output unit 830 based on the results sensed by the sensing unit 820. For example, if the number of puffs counted through the puff sensor 826 reaches a predetermined number, the control unit 810 can notify the user that the aerosol generator 800 will immediately shut down through at least one of the display unit 832, the haptic unit 834, and the acoustic output unit 836.
