Description

TECHNICAL FIELD

[0001] Various embodiments of the present application relate to an aerosol generating device capable of more effectively heating a tobacco rod. BACKGROUND

[0002] An aerosol generating device generally heats a rod by an electric resistance or induction method, thereby generating an aerosol.

[0003] In recent years, in order to improve the heat transfer efficiency to a tobacco rod, a method of using an infrared wavelength has been adopted. For example, a method of radiating infrared rays by directly applying a power source to an infrared radiation material such as a carbon nanotube, and heating a tobacco rod using the radiated infrared rays.

[0004] However, such an infrared radiation body has a problem in that, since it has a high electrical conductivity, an instantaneous heat increase phenomenon occurs if a power source is directly applied, thereby making it difficult to control heating. SUMMARY

[0005] PROBLEMS TO BE SOLVED BY THE INVENTION The technical problem to be solved by the present application is to provide an aerosol generating device that heats an infrared radiation body in a heat conduction manner by a heating body in contact with or adjacent to the infrared radiation body, without applying a separate power source to the infrared radiation body, and makes the heated infrared radiation body radiate infrared rays, in order to solve the above-mentioned problems.

[0006] The technical problem to be solved by the present application is not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.

[0007] MEANS FOR SOLVING THE PROBLEMS An aerosol generating device according to various embodiments of the present application can include a main body including an insertion space having an opening to allow at least a portion of a tobacco rod to be inserted into the insertion space, an infrared radiation body formed to be in contact with or adjacent to at least a portion of the tobacco rod in at least a portion of the insertion space, a heating body formed to be in contact with or adjacent to at least a portion of the infrared radiation body and to conduct heat to the infrared radiation body, and a control portion to apply a power source to the heating body.

[0008] In some embodiments, the infrared radiation body can be heated only by the heating body In some embodiments, the infrared radiation body can be formed to wrap the tobacco rod, and the heating body can be formed to wrap the infrared radiation body.

[0031] Figures 1 to 2 An aerosol generating apparatus 1 with respect to various embodiments of the present disclosure is shown.

[0032] Reference Figure 1 According to an embodiment of the present disclosure, the aerosol generating apparatus 1 may include at least one of a power supply 11, a control unit 12, a sensor 13, an infrared radiator 100, and a heating element 200. At least one of the power supply 11, control unit 12, sensor 13, infrared radiator 100, and heating element 200 may be disposed inside the body 10 of the aerosol generating apparatus 1. The body 10 may provide an upwardly opening space, allowing a cigarette stick S, which serves as an aerosol generating article, to be inserted into the space. This upwardly opening space may be referred to as an insertion space. The insertion space may be recessed into the interior of the body 10 to a predetermined depth, allowing at least a portion of the cigarette stick S to be inserted into the insertion space. The depth of the insertion space may correspond to the length of the region of the cigarette stick S containing the aerosol generating substance and / or medium. The lower end of the cigarette stick S may be inserted into the interior of the body 10, while the upper end of the cigarette stick S may protrude from the exterior of the body 10. A user may hold the exposed upper end of the cigarette stick S in their mouth and inhale air.

[0033] At least one of the infrared radiator 100 and the heating element 200 can heat the tobacco stick S. The infrared radiator 100 and the heating element 200 can extend upwards in an elongated shape within the space where the tobacco stick S is inserted. For example, the tobacco stick S can be cylindrical, while the infrared radiator 100 and the heating element 200 can be tubes with a hollow interior. The infrared radiator 100 and the heating element 200 can be disposed around the periphery of the insertion space. The infrared radiator 100 can be formed in at least a portion of the insertion space in a manner that contacts or is close to at least a portion of the tobacco stick S.

[0034] The infrared radiator 100 heats the cigarette stick S by radiating infrared wavelengths. Depending on the embodiment, the infrared radiator 100 may use carbon-based materials such as carbon nanotubes, ceramics, and other metals with high emissivity and heat resistance, but is not limited to these. The infrared radiator 100 heats the cigarette stick by radiating infrared wavelengths into its interior, causing vibrations in the medium of the cigarette stick's components. The infrared radiator 100 may have a thickness of less than 1 mm, but is not limited to this.

[0035] According to one embodiment, the infrared radiator 100 can be heated solely by the heating element 200. That is, the infrared radiator 100 itself does not receive a separate power source, but can receive heat solely through the heating element 200. Therefore, the infrared radiator 100 can be physically in direct contact with or near the heating element 200 without being connected to a separate power source. The infrared radiator 100 can be heated through direct contact with the heating element 200 or through a defined dielectric layer. The heat generated from the heating element 200 can heat the infrared radiator 100 to a specified temperature (e.g., 150~400°C) through heat conduction.

[0036] The heating element 200 may include a resistive heater and / or an induction heater.

[0037] For example, refer to Figure 1 The heating element 200 can be a resistance heater. For example, the heating element 200 may include a conductive track, through which the heating element 200 is heated when current flows. The heating element 200 can be electrically connected to the power supply 11. The heating element 200 can receive current from the power supply 11 and directly generate heat. The heating element 200 may be a hollow heater configured to enclose at least a portion of the cigarette stick S inserted into the insertion space and heat the exterior of the inserted cigarette stick S, or it may be a heater in the shape of a needle, rod, tube, etc., inserted into the interior of the cigarette stick S inserted into the insertion space and heat its interior. The heating element 200 may be implemented as a metal with a specified thermal conductivity, a heating film (e.g., a polyimide film), or an independent power supply capable of self-heating, but is not limited to these forms.

[0038] For example, refer to Figure 2 The aerosol generating device 1 may include an induction coil 201 surrounding a heating element 200. The induction coil 201 can generate heat in the heating element 200. The heating element 200 may be a strong magnet. The heating element 200 is a susceptor, and it can generate heat through the magnetic field produced by the alternating current (AC) flowing in the induction coil 201. The magnetic field can penetrate the heating element 200 and generate eddy currents within it. The current can generate heat in the heating element 200.

[0039] On the other hand, the inside of the cigarette stick S may include a sensor, and the sensor inside the cigarette stick S can generate heat through the magnetic field generated by the AC current flowing in the induction coil 201.

[0040] Traditionally, a separate power source is applied directly to the infrared radiator 100 to make it radiate infrared rays. However, if a power source is applied directly to a highly conductive infrared radiator such as carbon nanotubes, phenomena such as hot spots will occur, making heat control difficult. When the cigarette stick S is heated externally by the heating element 200, or when the cigarette stick S is heated by infrared rays generated by applying a separate power source to the infrared radiator 100, the rapid heating phenomenon can cause malfunctions in the internal structure of the aerosol generating device 1. In addition, the paper of the cigarette stick S may produce an odor due to high-temperature combustion.

[0041] To facilitate heat control of the infrared radiator 100, in this embodiment of the invention, heat conduction occurs between adjacent heating elements 200, initially heating both the infrared radiator 100 and the smoke stick S. The heating elements 200, heated by the power supply, then heat the infrared radiator 100 through heat conduction. The heat conducted to the infrared radiator 100 is then transferred back to the smoke stick S. Therefore, both the smoke stick S and the infrared radiator 100 are heated through heat conduction. Due to the material properties of the infrared radiator 100, this method achieves a smoother and more stable heating process compared to directly applying an independent power supply to the infrared radiator 100.

[0042] As the heating element 200 begins heating the tobacco stick S and a predetermined time passes, the infrared radiator 100, heated to a predetermined temperature, begins radiating infrared rays. The tobacco stick S is then reheated by the infrared rays radiated from the heating element 200. Due to the stable heating, the radiated infrared wavelengths can penetrate deeply into the interior of the tobacco stick S, thereby efficiently heating the tobacco medium contained within the tobacco stick S. In this situation, as the heating element 200 raises the temperature around the tobacco stick S, the heating process via infrared radiation or the heat conduction process through the infrared radiator can be achieved more effectively.

[0043] The power source 11 can supply power to the components of the aerosol generating apparatus 1 to ensure the operation of the components. The power source 11 can be referred to as a battery. The power source 11 can supply power to at least one of the control unit 12, sensor 13, and heating element 200. The power source 11 can supply power to the induction coil 201.

[0044] The control unit 12 can control the overall operation of the aerosol generating device 1. The control unit 12 can be mounted on a printed circuit board (PCB). The control unit 12 may include at least one processor. The control unit 12 can control the operation of at least one of the power supply 11, sensor 13, and heating element 200. The control unit 12 can control the operation of the induction coil 201. The control unit 12 can control the operation of the display, motor, etc., installed in the aerosol generating device 1. The control unit 12 can determine whether the aerosol generating device 1 is in an operational state by checking the status of each structure of the aerosol generating device 1.

[0045] The control unit 12 can analyze the results detected by the sensor 13 and control the subsequent processing. For example, the control unit 12 can control the power supplied to the heating element 200 based on the results detected by the sensor 13, thereby turning the heating element 200 on or off. For example, the control unit 12 can control the power supplied to the heating element 200 and the power supply time based on the results detected by the sensor 13, so that the heating element 200 is heated to a specified temperature or maintained at a suitable temperature.

[0046] Sensor 13 may include at least one of a temperature sensor, a suction sensor, an insertion detection sensor, and an acceleration sensor. For example, sensor 13 may detect at least one of the following: the temperature of the cigarette stick S, the temperature of the infrared radiator 100, the temperature of the heating element 200, the temperature of the power supply 11, and the internal and external temperatures of the body 10. For example, sensor 13 may sense the user's puff. For example, sensor 13 may sense whether the cigarette stick S has been inserted into the insertion space. For example, sensor 13 may sense the movement of the aerosol generating device 1.

[0047] Figure 3 This is a diagram showing a smoke rod heating structure 20 according to an embodiment of the present disclosure.

[0048] The smoke rod heating structure 20 can refer to a structure in the aerosol generating device 1 that includes at least one of the following: smoke rod S, infrared radiator 100, heating element 200, and adjacent main body 10.

[0049] In a cigarette holder heating structure 20 according to one embodiment, an infrared radiator 100 may be configured to directly contact at least a portion of the cigarette holder S inserted into the insertion space. Furthermore, the infrared radiator 100 may be configured to directly contact at least a portion of the heating element 200. The infrared radiator 100 and the heating element 200 may be arranged sequentially from the center of the cigarette holder S outwards.

[0050] exist Figure 3In the cigarette rod heating structure 20, the cigarette rod S, the infrared radiator 100, and the heating element 200 can be in contact without gaps. The infrared radiator 100 receives heat from the heating element 200 only and does not require a separate power supply. The infrared radiator 100 can serve as an intermediary layer between the cigarette rod S and the heating element 200, which are in contact without gaps, and can transfer the heat generated by the heating element 200 to the cigarette rod S through thermal conduction. Furthermore, the infrared radiator 100, having reached a certain degree of heating, radiates infrared rays, which further heat the cigarette rod S.

[0051] Figure 4 This is a diagram illustrating an aerosol generating apparatus 1 including a smoke rod heating structure 20, according to another embodiment of this disclosure. (Refer to...) Figure 5 To describe Figure 4 . Figure 5 From Figure 4 A cross-sectional view of the smoke rod heating structure 20 as observed from direction A.

[0052] The cigarette rod heating structure 20 may include structures with different diameters relative to the center point C of the cigarette rod S. This structure may include at least a portion of a region of a coating 50, an infrared radiator 100, an adhesive layer 150, a heating element 200, and a main body 10. The coating 50, infrared radiator 100, adhesive layer 150, and heating element 200 may be formed with diameters that gradually increase along the outer direction of the cigarette rod S. For example, with the center point C of the cigarette rod S as a reference, the diameter of the infrared radiator 100 may be larger than the diameter of the cigarette rod S, and the diameter of the heating element 200 may be larger than the diameter of the infrared radiator 100.

[0053] According to one embodiment, a coating 50 may be formed between the smoke stick S and the infrared radiator 100. This coating 50 improves the durability of the infrared radiator 100 and enables more stable heating of the smoke stick S. The inner side of the coating 50 may wrap around the smoke stick S, while the outer side of the coating 50 may contact the infrared radiator 100.

[0054] According to one embodiment, the coating 50 may be made of a material with a specified transparency to ensure that it does not interfere with infrared radiation. For example, the coating 50 may be made of materials such as quartz, sapphire, ceramic, or alumina, but is not limited thereto. The coating 50 may also be implemented such that at least a portion thereof is in contact with both the smoke stick S and the infrared radiator 100. The coating 50 may be implemented as a thin film coated on the infrared radiator 100.

[0055] According to one embodiment, an adhesive layer 150 for bonding the infrared radiator 100 and the heating element 200 can be formed between them. The inner side of the adhesive layer 150 can wrap around the infrared radiator 100, while the outer side of the adhesive layer 150 can contact the heating element 200.

[0056] According to one embodiment, the adhesive layer 150 can be formed with a relatively thin thickness to facilitate heat conduction. For example, the adhesive layer 150 can be formed in the form of a thin film, or it can be coated with a substance for adhesion. The adhesive layer 150 can also be implemented such that at least a portion of its area is in contact with the infrared radiator 100 and the heater 200, respectively.

[0057] On the other hand, although coating 50 and adhesive layer 150 are in Figure 4 The example provided is a case where the resistance heating element 200 is implemented as a resistance heater, but it is not limited to this. Figure 2 As shown, this method can also be applied to cases where the heating element 200 is an induction heating heater. In this case, an induction coil 201 can be additionally formed inside the main body 10 and outside the heating element 200.

[0058] As described above, through Figure 4 and Figure 5 The structure allows for more efficient implementation of heating based on heat conduction and heating based on infrared radiation. Figure 4 and Figure 5 The thicknesses of the structures shown are arbitrary for ease of illustration, and these structures can be implemented in various ways.

[0059] On the other hand, according to one embodiment, at least one of the infrared radiator 100 and the heating element 200 can be constituted as a detachable module, such as a detachable smoke rod heating structure, thereby allowing the aerosol generating device 1 to be disassembled and reassembled. According to different embodiments, the detachable smoke rod heating structure may further include... Figure 4 and Figure 5 At least one of the coating 50 and adhesive layer 150 shown.

[0060] According to different embodiments, the detachable, separate cigarette holder heating structure can be designed to be replaced without the use of additional tools. Therefore, the structures included in the separate cigarette holder heating structure can be made to be electrically or physically disconnected from the structures inside the aerosol generating device 1.

[0061] According to different embodiments, the separable smoke rod heating structure may include a frame for physically supporting at least one of the coating 50, infrared radiator 100, adhesive layer 150, and heating element 200. Furthermore, at least a portion of the frame may be open, thereby communicating with the insertion space of the aerosol generating device 1.

[0062] As mentioned above, the heating structure of the cigarette stick is composed of separate modules, thus eliminating the need for unnecessary internal structures for fixing the heating structure of the cigarette stick or the tedious cleaning process caused by cigarette stick residue.

[0063] Figure 6 This is a flowchart illustrating temperature feedback control according to an embodiment of the present disclosure. Figure 6 At least some of the steps in the process can be omitted or their order can be changed, and each step can be performed by the aerosol generating device 1 or the control unit 12.

[0064] The control unit 12 can control the heating element 200 (step S11). For example, the control unit 12 can control the power supply applied to the heating element 200 by controlling the amount of current transmitted from the power supply 11 to the heating element 200.

[0065] The control unit 12 can confirm the temperature of the smoke rod heating structure 20 (step S13). According to one embodiment, the control unit 12 can collect temperature data of at least one of the smoke rod S, the infrared radiator 100, the heating element 200, or any region inside the aerosol generating device 1 via the sensor 13.

[0066] The control unit 12 can control the power applied to the heating element 200 based on the collected temperature data (step S15).

[0067] For example, if at any given time the temperature of the infrared radiator 100 has not reached the appropriate temperature required for emitting infrared rays, the control unit 12 can increase the amount of current applied from the power supply 11 to the heating element 200 or the induction coil 201. For example, the appropriate temperature required for emitting infrared rays can be preset as a first threshold. The first threshold can be preset in a memory based on the material properties of the infrared radiator 100, etc.

[0068] For example, if the infrared radiator 100 emits excessive infrared radiation, the control unit 12 can reduce the amount of current applied to the heating element 200. The temperature value at which excessive infrared radiation is emitted can be experimentally preset as a second threshold. At any time, when it is determined that the temperature of the infrared radiator 100 is above the second threshold, the control unit 12 can reduce the amount of current applied to the heating element 200 or the induction coil 201. This second threshold can be set to a value higher than the first threshold.

[0069] On the other hand, the first and second thresholds described above are not limited to the temperature of the infrared radiator 100, but can also be set according to the temperature of the smoke stick S and the heating element 200.

The upper shell 40 may include a cover 45 for opening and closing the insertion port 44. The cover 45 can slide laterally to open and close the insertion port 44.

[0072] The upper shell 40 may include upper shell wings 42. The upper shell wings 42 may extend downward from both sides of the upper shell body. The upper shell wings 42 may be named upper shell grips 42.

[0073] The main body 10 may include main body wings 16. Main body wings 16 may extend upwards from the upper edge of the main body 10. The main body wings 16 may be formed as a pair symmetrical about the upper part of the main body 10. The main body wings 16 may be formed at a position offset from the upper shell wing 42.

[0074] When the upper shell 40 is combined with the main body 10, the upper shell 40 can form the upper appearance of the aerosol generating device 1. When the upper shell 40 is combined with the main body 10, the main body wing 16 can cover the side portion of the upper shell 40 exposed between the upper shell wings 42. When the upper shell 40 is combined with the main body 10, the upper shell wings 42 can cover the outer side wall of the main body 10.
