[0030] Figures 1a to 1c This is a diagram illustrating an example of an aerosol generating apparatus according to one embodiment.

[0031] Figures 1a to 1c This is a diagram showing an example of an aerosol generating apparatus. Figures 1a to 1c An example is shown of inserting a cigarette (hereinafter, it may be used with the same meaning as "aerosol generating article" or "cigarette") into an aerosol generating device.

[0032] Reference Figures 1a to 1c The aerosol generating device 1 may include: a battery 11, a control unit 12, a heater 18, and a smoke cartridge 19.

[0033] Reference Figure 1a The aerosol generating device 1 includes: a battery 11, a control unit 12, and a heater 18. (See reference...) Figure 1b The aerosol generating device 1 also includes a smoke cartridge 19. The internal space of the aerosol generating device 1 can accommodate an aerosol generating item S.

[0034] When the aerosol generating article S is inserted into the aerosol generating device 1, the aerosol generating device 1 can generate aerosol by activating the heater 18 and / or the cartridge 19. The aerosol generated by the heater 18 and / or the cartridge 19 passes through the aerosol generating article S and is delivered to the user. If necessary, the aerosol generating device 1 can heat the heater 18 even if the aerosol generating article S is not inserted into the aerosol generating device 1.

[0035] Alternatively, heater 18 can be omitted. (See reference...) Figure 1c The aerosol generating device 1 includes: a battery 11, a control unit 12, and a smoke cartridge 19. Figure 1c The aerosol generating device 1 is not equipped with a space for inserting the aerosol generating article S, and is not equipped with a heater 18 for heating the aerosol generating article S.

[0036] Figures 1a to 1c The aerosol generating apparatus 1 shown in the diagram illustrates the components relevant to this embodiment. Therefore, those skilled in the art who relate this embodiment will understand that, in addition to... Figures 1a to 1c In addition to the components shown, the aerosol generating apparatus 1 may also include other common components.

[0037] Figures 1a to 1c In the aerosol generating apparatus 1 shown, the components are arranged in a row. However, the internal structure of the aerosol generating apparatus 1 is not limited to that shown. For example, the cartridge 19 and the heater 18 can be arranged side by side. In other words, the arrangement of the battery 11, the control unit 12, the heater 18, and the cartridge 19 can be changed depending on the design of the aerosol generating apparatus 1.

[0038] Battery 11 provides power to operate aerosol generating device 1. For example, battery 11 can supply power to heat heater 18 or smoke cartridge 19, and can also supply power required for control unit 12 to operate. In addition, battery 11 can supply power required for the operation of displays, sensors, motors, etc. installed on aerosol generating device 1.

[0039] The battery 11 can be a removable (detachable, separate) power source. The battery 11 is provided with electrical contacts, and when the battery 11 is installed in the aerosol generating device 1, the electrical contacts of the battery 11 are electrically connected to the electrical contacts provided in the aerosol generating device 1, thereby enabling power supply to the aerosol generating device 1. Alternatively, the battery 11 can also be provided with a charging coil instead of separate electrical contacts, thereby supplying power to the aerosol generating device 1 via wireless charging. That is, the power supply method of the battery 11 can be diversified, and the electrical connection method between the battery 11 and the aerosol generating device 1 can be changed depending on the power supply method supported by the battery 11.

[0040] The removable battery 11 may be provided with a charger interface that can be connected to an external charger. Power for charging the removable battery 11 can be provided to the battery 11 through the charger interface. The battery 11 can be charged by an external charger in a state that is connected to or disconnected from the aerosol generating device 1.

[0041] The control unit 12 provides overall control over the operation of the aerosol generating device 1. Specifically, the control unit 12 controls not only the battery 11, heater 18, and cartridge 19, but also the operation of other structural components within the aerosol generating device 1. Furthermore, the control unit 12 can also check the status of each structural component of the aerosol generating device 1 to determine whether the aerosol generating device 1 is in an operational state.

[0042] The control unit 12 includes at least one processor. The processor can be implemented using multiple logic gate arrays, or it can be implemented using a combination of a general-purpose microprocessor and a memory storing programs that can be executed in the microprocessor. Furthermore, as will be understood by those skilled in the art to which this embodiment pertains, it can also be implemented using other forms of hardware.

[0043] The heater 18 can be heated using electricity supplied from the battery 11. For example, when a cigarette is inserted into the aerosol generating device 1, the heater 18 can be located outside the cigarette. Therefore, the heated heater 18 can raise the temperature of the aerosol generating substance inside the cigarette.

[0044] Heater 18 can be a resistance heater. For example, heater 18 includes a conductive track, through which current flows, and heater 18 can be heated. However, heater 18 is not limited to the above example; there are no limitations as long as it can heat to the desired temperature. The desired temperature can be preset in the aerosol generating device 1, or it can be set by the user to the desired temperature.

[0045] On the other hand, as another example, heater 18 can be an induction heating heater. Specifically, the aerosol generating device 1 may include an induction coil (not shown) surrounding heater 18. When power is supplied to the induction coil via battery 11, the induction coil can heat heater 18. Heater 18 is a susceptor, and heater 18 can be heated by the magnetic field generated by the alternating current flowing through the induction coil. The magnetic field can penetrate heater 18 and generate eddy currents within heater 18. The current can generate heat in heater 18.

[0046] On the other hand, cigarettes may include sensors that can be heated by an induction heating heater. The interior of the cigarette may include sensors that can be heated by the magnetic field generated by an alternating current flowing through an induction coil.

[0047] Figure 1a and Figure 1b The heater 18 is shown disposed outside the aerosol generating article S, but is not limited thereto. The heater 18 may include a tubular heating element, a plate heating element, a needle heating element, or a rod heating element, and may heat the interior or exterior of the aerosol generating article S depending on the shape of the heating element.

[0048] Additionally, the aerosol generating apparatus 1 may be equipped with a plurality of heaters 18. In this case, the plurality of heaters 18 may be configured to be inserted inside the aerosol generating article S, or they may be configured to be disposed outside the aerosol generating article S. Furthermore, some of the plurality of heaters 18 may be configured to be inserted inside the aerosol generating article S, while the remaining heaters may be disposed outside the aerosol generating article S. The shape of the heaters 18 is not limited to... Figure 1a and Figure 1b The shape shown can also be made into many other shapes.

[0049] The smoke cartridge 19 can generate an aerosol by heating a liquid phase composition. The generated aerosol can pass through the aerosol-generated item S and be delivered to the user.

[0050] In other words, the aerosol generated by the smoke cartridge 19 can move along the airflow channel of the aerosol generating device 1. Figure 1a and Figure 1b In this process, aerosols moving along the airflow channel can pass through the aerosol to generate items S and deliver them to the user. Figure 1c In the process, aerosols moving along the airflow channel can pass through the mouthpiece 20 and be delivered to the user.

[0051] The cartridge 19 may include, but is not limited to, a liquid storage unit, a liquid delivery unit, and a cartridge heater. For example, the liquid storage unit, the liquid delivery unit, and the cartridge heater may also be included as independent modules in the aerosol generating apparatus 1.

[0052] The liquid storage unit can store a liquid phase composition. For example, the liquid phase composition can be a liquid containing tobacco-containing substances with volatile tobacco flavor components, or it can be a liquid containing non-tobacco substances. The liquid storage unit can be made to be detachable from or installed on the cartridge 19, or it can be integrated with the cartridge 19.

[0053] For example, the liquid-phase composition may include water, solvent, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures. Fragrances may include, but are not limited to, menthol, peppermint oil, various fruit flavorings, etc. Flavorings may include ingredients capable of providing the user with a variety of fragrances or smoky flavors. Vitamin mixtures may be, but are not limited to, a mixture of at least one of vitamins A, B, C, and E. Additionally, the liquid-phase composition may include aerosol forming agents, such as glycerol and propylene glycol.

[0054] The liquid transfer unit can transfer the liquid phase composition from the liquid storage section to the heating element. For example, the liquid transfer unit can be a core such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic, but is not limited to these.

[0055] A cartridge heater is a component used to heat a liquid-phase composition delivered by a liquid delivery unit. Cartridge heaters can be metal heating wires, metal heating plates, ceramic heaters, etc., but are not limited to these, and can include various methods of generating aerosols from aerosol-generating substances.

[0056] As an example, the cartridge heater can be constructed from a conductive filament such as nickel-chromium wire and can be configured to be wound around a liquid delivery unit. The cartridge heater can be heated using a supplied current and transfer heat to the liquid composition in contact with the cartridge heater to heat the liquid composition. As a result, an aerosol can be generated.

[0057] As another example, the cartridge heater is made of a sensory material that is heated by means of an induced magnetic field, and can be heated by means of an induced magnetic field generated in an induction coil that is separately arranged from the heating element.

[0058] As another example, a cartridge heater could be an ultrasonic vibrator that generates aerosols from aerosol-generating substances using ultrasonic vibration. The ultrasonic vibration method can refer to the process of generating aerosols by atomizing the aerosol-generating substances using ultrasonic vibrations produced by the vibrator.

[0059] The cartridge heater can be integrated into the liquid delivery unit not only through structural features such as winding it around the liquid delivery unit, but also permanently or reversibly attached to the liquid delivery unit through methods such as coating, spraying, deposition, electroplating, impregnation, painting, printing, 3D printing, or using structural components. Alternatively, the cartridge heater can be positioned within the liquid delivery unit during manufacturing by sintering it together with the liquid delivery unit. However, the arrangement of the cartridge heater is not limited to the examples described above and can include various methods that allow it to be positioned within the liquid delivery unit while maintaining its functionality.

[0060] A cartridge heater can be called an electronic cartomizer or an atomizer, but is not limited to these terms.

[0061] The cartridge 19 can be inserted into or removed from the body of the aerosol generating device 1 or the aerosol generating device 1. If the aerosol generating substance stored in the cartridge 19 is depleted, the aerosol generating substance can be replenished to the cartridge 19, or it can be replaced with another cartridge 19 that stores aerosol generating substance.

[0062] On the other hand, the aerosol generating device 1 may also include other general structural components besides the battery 11, control unit 12, heater 18, and cartridge 19. For example, the aerosol generating device 1 may include a display capable of outputting visual information and / or a motor for outputting tactile information. Additionally, the aerosol generating device 1 may include at least one sensor (inhalation detection sensor, temperature detection sensor, cigarette insertion detection sensor, etc.). Furthermore, the aerosol generating device 1 may be configured to allow external air to flow in or internal gas to flow out even when the aerosol generating article S is inserted.

[0063] Although not in Figures 1a to 1c As shown, the aerosol generating device 1 can also be configured as a system with a separate bracket. For example, the bracket can be used to charge the battery 11 of the aerosol generating device 1. Alternatively, the heater 18 can be heated while the bracket and the aerosol generating device 1 are combined.

[0064] The aerosol-generating article S can be similar to a regular combustible cigarette. For example, the aerosol-generating article S can be divided into a first part S1, which includes aerosol-generating substances, and a second part S2, which includes a filter, etc. The first part S1 can be referred to below as the "medium part".

[0065] The second part S2 of the aerosol-generating article S may also include an aerosol-generating substance. For example, an aerosol-generating substance in the form of particles or capsules may be inserted into the second part S2.

[0066] The entire first part S1 is inserted into the aerosol generating device 1, while the second part S2 may be exposed to the outside. Alternatively, only a portion of the first part S1 may be inserted into the aerosol generating device 1, or the entire first part S1 and a portion of the second part S2 may be inserted into the aerosol generating device 1. The user can inhale the aerosol while holding the second part S2 in their mouth. At this time, external air passes through the first part S1 to generate aerosol, which then passes through the second part S2 and is delivered to the user's mouth.

[0067] Figure 2This is a perspective view schematically showing an aerosol generating apparatus according to an embodiment of the present disclosure.

[0068] Reference Figure 2 According to one embodiment, the aerosol generating apparatus 1 may include: a main body 1100, a heater 1200, and a battery 1300.

[0069] The main body 1100 forms the overall appearance of the aerosol generating device 1 and may include an internal space capable of arranging the constituent elements of the aerosol generating device 1. Although only an embodiment in which the overall cross-section of the main body 1100 is formed into a quadrangular prism shape is shown in the drawings, the shape of the main body 1100 is not limited to this; the main body 1100 may be formed entirely into a cylindrical shape, or it may also be formed into a polygonal prism shape.

[0070] The body 1100 may include an opening 1100h through which the aerosol-generating article S can be inserted into the interior of the body 1100. At least a portion of the aerosol-generating article S can be inserted into or contained within the interior of the body 1100 through the opening 1100h.

[0071] The main body 1100 may include a receiving space 1100i that internally accommodates the aerosol-generating article S. The receiving space 1100i may be formed on the upper part of the main body 1100. The receiving space 1100i may open upward and connect to the opening 1100h.

[0072] The accommodating space 1100i can have a cylindrical shape that extends relatively long in the vertical direction. At least a portion of the aerosol generating article S can be accommodated inside the main body 1100 through the opening 1100h on the upper side of the accommodating space 1100i. In this case, the depth of the accommodating space 1100i of the aerosol generating article S can correspond to the length of the region in the aerosol generating article S that includes the aerosol generating substance or medium.

[0073] Heater 1200 (e.g., Figure 1a and Figure 1b The heater 18) can generate aerosols from the aerosol generating article S contained in the containment space 1100i. The heater 1200 can extend relatively long in the vertical direction along the containment space 1100i.

[0074] According to one embodiment, heater 1200 may surround at least a portion of receiving space 1100i. As an example, heater 1200 may be a cylindrical resistance heater surrounding at least a portion of receiving space 1100i. As another example, heater 1200 may include: a cylindrical sensor surrounding at least a portion of receiving space 1100i; and an induction coil surrounding the sensor. Heater 1200 may heat the exterior of aerosol generating article S housed in receiving space 1100i. However, embodiments are not limited to the shape and arrangement of heater 1200. In another embodiment, heater may be inserted inside aerosol generating article S.

[0075] At least one area of ​​the aerosol generating article S contained in the containment space 1100i can be heated by the heater 1200, and the aerosol generated by heating the aerosol generating article S is mixed with air flowing into the interior space of the body 1100 through an air inlet (e.g., opening 1100h) formed in a region of the body 1100, thereby generating an aerosol.

[0076] On the other hand, heater 1200 can be Figure 1b and Figure 1c The cigarette cartridge heater. In this case, the aerosol generating item S can be... Figure 1b and Figure 1c The cartridge is 19, not a cigarette or a cigarette holder.

[0077] According to one embodiment, the aerosol generating device 1 may include a battery 1300 that supplies power required for the operation of the aerosol generating device 1. In this case, the battery 1300 may be... Figures 1a to 1c Battery 11.

[0078] Reference Figure 2 The battery 1300 can be detachably coupled to the body 1100. For example, the battery 1300 can be inserted into the body 1100 in the +z direction from a position spaced apart from the body 1100 in the –z direction and coupled to a region of the body 1100. Specifically, the battery 1300 can be coupled to the body 1100 by rotating relative to the body 1100 while moving in a direction (e.g., the +z direction) toward the interior of the body 1100. Hereinafter, the manner in which the battery 1300 is coupled can be described as a “threaded coupling”.

[0079] Below, refer to Figure 3a and Figure 3b The structure of the battery 1300 used for bonding with the main body 1100 is described in detail.

[0080] Figure 3a It shows that it can be applied to Figure 2 A three-dimensional view of the battery of the aerosol generation device. Figure 3b It is cut along the III-III direction. Figure 3a A cross-sectional view of the battery.

[0081] Reference Figure 3a and Figure 3b Battery 1300 can be used with Figures 1a to 1c Battery 11 or Figure 2 The battery is the same as or similar to the 1300.

[0082] like Figure 3a As shown, the battery 1300 may include, but is not limited to, a cylindrical shape, and may include various shapes that can rotate and connect relative to the body. Additionally, in Figure 3a In the figure, the battery is shown as a circular shape in the xy plane and extends relatively long along the z-axis, but the battery specifications are not limited to those shown in the figure.

[0083] Battery 1300 may include: a protrusion 1310 protruding from the outer peripheral surface of battery 1300 so as to be detachably attached to a body (e.g., Figure 2 The main body 1100). The protrusion 1310 is a structural element used to connect with the main body.

[0084] The protrusion 1310 may include a shape that wraps around the outer peripheral surface of the battery 1300 and extends along the length direction (e.g., the z-axis direction) of the battery 1300. In this case, the number of turns of the protrusion 1310 around the battery is not limited to that shown in the figure.

[0085] The protrusion 1310 is inserted into a guide groove formed on the inner side of the body via a threaded connection between the battery 1300 and the body, thereby being supported by a region of the body facing the guide groove. By having the protrusion 1310 supported by the guide groove, the battery 1300 can be supported by the body.

[0086] On the other hand, one end of the battery 1300 inserted into the main body can be referred to as the front end 1300a of the battery 1300, and the other end of the battery 1300 facing the opposite direction can be referred to as the rear end 1300b of the battery 1300.

[0087] The front end 1300a of the battery may be provided with a supply terminal 1320 for supplying power to the internal components of the main body 1100. As shown, although two supply terminals 1320 are configured, the embodiment is not limited by the number of supply terminals. The rear end 1300b of the battery 1300 may face outwards from the main body 1100. The rear end 1300b may be inserted into the main body 1100 or exposed to the outside of the main body 1100.

[0088] Figure 4 This shows the battery and its applicability. Figure 2A cross-sectional view of an example of the main body of an aerosol generating device.

[0089] Reference Figure 4 The aerosol generating apparatus according to the embodiment may include: a main body 1100, a battery 1300, a receiving terminal 1400, and an airflow channel 1500.

[0090] Figure 4 At least one of the components of the aerosol generating device 1 shown can be connected with Figure 2 At least one of the constituent elements of the aerosol generating device 1 and Figure 3a The batteries are the same as or similar to the 1300, and repeated descriptions will be omitted below.

[0091] The main body 1100 may include a bonding space 1100c for bonding with a battery, the bonding space 1100c being connected to a receiving space (e.g., Figure 2 The accommodating space 1100i) is separated. The bonding space 1100c of the main body 1100 can be opened in the -z direction, so that the separate battery can be inserted into the bonding space 1100c.

[0092] The space 1100c can include a shape corresponding to the shape of the battery. For example, the space 1100c can be a cylindrical groove that is circular in the xy plane and extends longer along the z-axis.

[0093] A receiving terminal 1400 protruding toward the bottom surface of the bonding space 1100c can be disposed there. As the battery 1300 rotates relative to the main body 1100 and moves along the length direction of the battery 1300, the supply terminal 1320 disposed at the front end 1300a of the battery 1300 can contact the receiving terminal 1400. Therefore, power can be supplied to the internal components of the aerosol generating apparatus 1.

[0094] When the battery 1300 is inserted into the coupling space 1100c, the receiving terminal 1400 can be configured in a position corresponding to the supply terminal 1320 of the battery 1300. For example, in Figure 4 In this embodiment, two receiving terminals 1400 are configured and are located in the periphery of the connection channel 1100p described later. The embodiment is not limited by the number and position of the receiving terminals 1400.

[0095] The body 1100 may include a guide groove 1110, configured to extend along the rotational direction of the battery 1300 and inclined toward the length direction (e.g., the z-axis direction) of the battery 1300, so that the protrusion 1310 is inserted into the guide groove 1110. That is, the protrusion 1310 and the guide groove 1110 may include corresponding shapes so that the protrusion 1310 and the guide groove 1110 engage with each other. As described above, the protrusion 1310 is inserted into and moves along the guide groove 1110, thereby allowing the battery 1300 to be threadedly engaged with the body 1100.

[0096] At this time, the space between the battery 1300, which is coupled to the main body 1100, and the main body 1100 can become an airflow channel 1500 for air movement. To ensure sufficient space between the threadedly coupled battery 1300 and the main body 1100, the volume of the protrusion 1310 can be smaller than the volume of the guide groove 1110. Figure 4 To explain, in the cross-section along the length of the battery 1300, the area of ​​the protrusion 1310 may be smaller than the area of ​​the guide groove 1110.

[0097] Therefore, a space can be provided between the protrusion 1310 and the guide groove 1110 to enclose the outer peripheral surface of the battery 1300 and extend along the length direction (e.g., the z-axis direction) of the battery 1300, and such a space can become an airflow channel 1500 for the inflow of external air into the aerosol generating device 1.

[0098] The airflow channel 1500 can begin at the entrance of the junction space 1100c at the rear end 1300b of the battery 1300. The gap between the outer peripheral surface of the battery 1300 and the inner surface of the body 1100 constituting the junction space 1100c can serve as the starting point of the airflow channel 1500.

[0099] Air moving along the space between the protrusion 1310 and the guide groove 1110 can reach the bottom surface of the connecting space 1100c. The main body 1100 may include a connecting channel 1100p, which connects to the receiving space 1100i on the bottom surface of the connecting space 1100c. Therefore, air reaching the bottom surface of the connecting space 1100c can move along the connecting channel 1100p, which is open in the center of the bottom surface. At this time, the position of the connecting channel 1100p is not limited to that shown in the figure.

[0100] On the other hand, the protrusion 1310 and the guide groove 1110 can be configured opposite to each other. For example... Figure 4 As shown, the protrusion 1310 is disposed on the outer peripheral surface of the battery 1300, and the guide groove is disposed on the inner side surface of the main body 1100 constituting the coupling space 1100c. However, according to the embodiment, the protrusion 1310 may be disposed on the inner side surface of the main body 1100, and the guide groove 1110 may be disposed on the outer peripheral surface of the battery 1300.

[0101] Those skilled in the art will readily understand that the protrusion 1310 can be configured in one of the battery 1300 and the body 1100, and the guide groove 1110 can be configured in the other of the battery 1300 and the body 1100.

[0102] Below, refer to Figure 5a and Figure 5b The structural element that stops the movement of the battery 1300 relative to the main body 1100 will be described.

[0103] Figure 5a and Figure 5b These are cross-sectional views showing examples of the battery combined with the main body of an aerosol generating apparatus applicable to an embodiment.

[0104] Reference Figure 5a and Figure 5b According to the embodiment, the aerosol generating device 1 may include: a main body 1100, a battery 1300, a receiving terminal 1400, and an airflow channel 1500.

[0105] Figure 5a and Figure 5b At least one of the components of the aerosol generating device 1 shown can be connected with Figure 4 The aerosol generating device 1 is the same as or similar to the aerosol generating device 1, and repeated descriptions will be omitted below.

[0106] Reference Figure 5a The aerosol generating device 1 may further include a stop 1600 that contacts the front end portion 1300a of the battery 1300 and limits the range of movement of the protrusion 1310. The stop 1600 may be configured to form a bonding space (e.g., Figure 4 The inner side of the main body 1100 of the combined space 1100c).

[0107] When the battery 1300 first rotates relative to the main body 1100 and moves along the length of the battery 1300, and then the front end 1300a of the battery 1300 reaches the stop member 1600, the battery 1300 will no longer be able to rotate or move linearly. At this time, the supply terminal 1320 and the receiving terminal 1400 of the battery 1300 can come into contact with each other.

[0108] Therefore, when the battery 1300 is no longer moving relative to the body 1100, power can be supplied from the battery 1300 to the internal components of the aerosol generating device 1. When the user feels that the battery 1300 is not rotating or moving linearly relative to the body 1100, the user can be certain that the battery 1300 is fully engaged in the engagement space 1100c (e.g., the supply terminal is in contact with the receiving terminal).

[0109] Reference Figure 5b The battery 1300 may include a boss 1330 at its rear end 1300b, which restricts the movement of the battery 1300 relative to the body 1100. The boss 1330 may protrude outward from the rear end 1300b.

[0110] In the illustrated embodiment, the main body 1100 may include a circular groove 1120, which is formed at the entrance of the mating space 1100c corresponding to the boss 1330 for insertion of the boss 1330, and extends along the length direction of the mating space 1100c. The circular groove 1120 may include a shape corresponding to the boss 1330. For example, the inner diameter of the circular groove 1120 may be larger than the inner diameter of the mating space 1100c.

[0111] The circular groove 1120 can restrict the movement of the boss portion 1330 along the length direction of the mating space 1100c or the length direction of the battery 1300 (e.g., the z-axis direction). When the battery 1300 first rotates relative to the body 1100 and moves along its length direction, and then the boss portion 1330 of the battery 1300 located at the rear end 1300b is placed in the circular groove 1120, the battery 1300 will no longer be able to rotate or move linearly because the circular groove 1120 blocks the z-axis movement of the boss portion 1330. At this time, the supply terminal 1320 and the receiving terminal 1400 of the battery 1300 can contact each other.

[0112] Therefore, when the battery 1300 is no longer moving relative to the body 1100, power can be supplied from the battery 1300 to the internal components of the aerosol generating device 1. When the user feels that the battery 1300 is not rotating or moving linearly relative to the body 1100, or visually confirms that the boss 1330 is accommodated in the circular groove 1120, the user can confirm that the battery 1300 is fully engaged in the engagement space 1100c (e.g., the supply terminal is in contact with the receiving terminal).

[0113] On the other hand, the protrusion 1330 protruding from the outer peripheral surface of the battery 1300 will block the airflow channel 1500, which may prevent air from flowing into the airflow channel 1500. To solve this problem, the protrusion 1330 of the battery 1300 may be provided with an inlet 1330h for allowing air from outside the aerosol generating device 1 to flow in.

[0114] Since the battery 1300 includes an inlet 1330h that penetrates the boss portion 1330, air can move along the airflow channel 1500 formed between the battery 1300 and the main body 1100 after penetrating the boss portion 1330 of the battery 1300 and flowing into the interior of the coupling space 1100c.

[0115] Figure 6 This is an illustrative representation of what can be applied. Figure 2 A diagram of the airflow channel of the aerosol generation device.

[0116] Reference Figure 6 According to another embodiment, the aerosol generating apparatus 1 may include: a main body 1100, a heater 1200, a battery 1300, a receiving terminal 1400, and an airflow channel 1500.

[0117] Figure 6 At least one of the components of the aerosol generating device 1 shown can be connected with Figure 2 and Figure 4 At least one of the constituent elements of the aerosol generating device 1 shown is the same or similar, and repeated descriptions will be omitted below.

[0118] As described above, the airflow channel 1500 can begin at the entrance of the coupling space 1100c at the rear end 1300b of the battery 1300. The gap between the outer peripheral surface of the battery 1300 and the inner surface of the body 1100 constituting the coupling space 1100c can serve as the starting point of the airflow channel 1500.

[0119] Air can move along the empty space surrounding the outer periphery of the battery 1300 and extending along the length of the battery. The moving air can reach the bottom surface of the connection space 1100c. The air can meander around the portion where the receiving terminal 1400 and the supply terminal 1320 are configured and flow into the connection channel 1100p.

[0120] Air moving from the bottom of the bonding space 1100c along the connecting channel 1100p can reach the containment space 1100i. Air flowing into one end of the aerosol generating article S contained in the containment space 1100i can mix with the gasified particles generated by heating the aerosol generating article S by the heater 1200, thereby forming an aerosol.

[0121] The aerosol can move along the aerosol generating article S and can flow into the mouth of the user of the aerosol generating device 1 through the other end of the aerosol generating article S located around the opening 1100h.

[0122] In summary, the bonding space 1100c of the battery 1300 can be fluidly connected to the containing space 1100i of the aerosol generating article S via the connecting channel 1100p. Here, "fluidly connected" or "fluidly linked" can mean that the constituent elements are connected so that fluids such as air can pass through and flow through these constituent elements.

[0123] The combining space 1100c and the containing space 1100i can open in opposite directions. Since the airflow channel 1500 can be configured to extend from the outside of the aerosol generating device 1 along the combining space 1100c and the containing space 1100i, the aerosol generating device 1 can include a relatively simple airflow channel 1500. Here, the airflow channel 1500 refers not only to the empty space between the battery 1300 and the main body 1100, but also to the channel that fluidly connects the combining space 1100c, the connecting channel 1100p, and the containing space 1100i.

[0124] On the other hand, the battery 1300, which is integrated into the main body 1100, can be detached by the user. Below, through... Figure 7 and Figure 8 The structural components used to separate battery 1300 are described.

[0125] Figure 7 This is a perspective view showing the rear end 1300b of a battery that can be applied to an aerosol generating apparatus according to yet another embodiment.

[0126] Reference Figure 7 According to another embodiment, the aerosol generating apparatus 1 may include a main body 1100 and a battery 1300.

[0127] Figure 7 At least one of the components of the aerosol generating device 1 shown can be connected with Figure 2 and Figure 4 At least one of the constituent elements of the aerosol generating device 1 shown is the same or similar, and repeated descriptions will be omitted below.

[0128] The battery 1300 may include an insertion slot 1340 disposed at one end. The insertion slot 1340 is a structural element disposed at the rear end 1300b of the battery 1300 for transmitting an operating force applied by a user to detach the battery 1300 attached to the body 1100 from the body 1100.

[0129] When the battery 1300 is being inserted into or separated from the coupling space 1100c, the user can hold the outer peripheral surface of the battery 1300 and rotate the battery 1300 naturally.

[0130] However, with the battery 1300 fully inserted into the bonding space 1100c, the user cannot hold the outer peripheral surface of the battery 1300, making it difficult to rotate the battery 1300. At this time, an insertion groove 1340 can be provided at the rear end 1300b of the battery 1300, which is exposed to the outside of the aerosol generating device 1. When the user applies an operating force to the insertion groove 1340 to separate the battery 1300, the battery 1300 can rotate in the opposite direction to the direction of rotation when bonded to the body 1100 while moving along the length of the battery 1300.

[0131] For example, if the battery 1300 is rotated clockwise and moved in the +z direction relative to the body 1100 in order to combine the battery 1300 with the body, then in order to separate the battery 1300 from the body 1100, the battery 1300 can be rotated counterclockwise and moved in the -z direction relative to the body 1100.

[0132] To allow the battery 1300 to be rotated using the insertion slot 1340, a user-usable ordinary tool or the user's fingernail can be inserted into the insertion slot 1340. The insertion slot 1340 can be used not only for separating the battery 1300, but also for rotating the battery 1300 to fully engage it.

[0133] As shown in the figure, the insertion slot 1340 may include a slot shape that extends elongated in a straight line on the xy plane, but the embodiment is not limited to the shape of the insertion slot 1340. The insertion slot 1340 may include various shapes that enable the battery 1300 to rotate and move linearly when the user applies an operating force for rotating the battery.

[0134] Figure 8 This is a cross-sectional view showing the battery and cover combined with the main body of an aerosol generating apparatus that can be adapted to yet another embodiment.

[0135] Reference Figure 8 According to another embodiment, the aerosol generating device 1 may include: a main body 1100, a battery 1300, and a cover 1700.

[0136] Figure 8 At least one of the components of the aerosol generating device 1 shown can be connected with Figure 2 and Figure 4 At least one of the constituent elements of the aerosol generating device 1 shown is the same or similar, and repeated descriptions will be omitted below.

[0137] The cover 1700 is a structural element disposed at one end of the battery (e.g., the rear end 1300b) and used to protect the battery 1300 which is coupled to the body 1100. The cover 1700 may also be coupled to the body 1100 to protect the battery 1300.

[0138] The main body 1100 may include a guide 1130 disposed inside the cover 1700 and engaging with the cover 1700 for engagement. The manner in which the cover 1700 engages with the guide 1130 is not limited to a specific embodiment. As one example, the guide 1130 may be interference-fitted to the cover 1700, or conversely, the cover 1700 may be interference-fitted to the guide 1130. As another example, the guide 1130 and the cover 1700 may be threaded together. As yet another example, the guide 1130 and the cover 1700 may be magnetically engaged using a magnet.

[0139] The cover 1700 can cover the rear end 1300b of the battery 1300 and seal the interior of the cover 1700, thereby protecting the battery 1300. Accordingly, the inlet of the airflow channel 1500 between the battery 1300 and the body 1100 is blocked by the cover 1700, which may prevent fluid connection with the outside of the aerosol generating device 1.

[0140] That is, in order for the airflow passage 1500 of the aerosol generating device 1 to function properly, an additional hole for airflow is required in the cover 1700. The cover 1700 may include a first airflow hole 1710 for allowing external air to flow in. Even with the cover 1700 present, the airflow passage 1500 can be fluidly connected to the outside of the aerosol generating device 1 via the first airflow hole 1710.

[0141] On the other hand, the battery 1300 may include a protrusion 1350 disposed at one end. The protrusion 1350 is disposed at the rear end 1300b of the battery 1300 and can protrude outward from the body 1100 when the battery 1300 is inserted into the body 1100.

[0142] With the insertion slot (e.g., Figure 7 Similarly, the protrusion 1350 is a structural element configured to make it difficult to rotate the battery 1300 when the battery 1300 is fully inserted into the coupling space 1100c, because the user cannot hold the outer peripheral surface of the battery 1300.

[0143] The protrusion 1350 can extend from the rear end 1300b of the battery 1300 and be exposed to the outside of the aerosol generating device 1. The user can rotate the battery by holding the protrusion 1350 and applying an operating force to separate the battery 1300.

[0144] Therefore, the battery 1300 can rotate in the opposite direction to the direction of rotation when it is engaged with the body 1100 while moving along the length of the battery 1300. Similar to the insertion slot, the protrusion 1350 can be used not only for separating the battery 1300, but also for rotating the battery 1300 to fully engage the battery 1300.

[0145] At this time, the aerosol generating device 1 may further include a pressurizing member 1800, which contacts the protrusion 1350 of the battery 1300 and is used to pressurize the battery 1300 toward the body 1100. Due to the space between the protrusion 1310 of the battery 1300 and the guide groove 1110 of the body 1100, the battery 1300 can move in the opposite direction to the insertion direction of the battery 1300.

[0146] Accordingly, the receiving terminal (e.g., Figure 4 The receiving terminal 1400) and the supply terminal of the battery 1300 (e.g., Figure 4 The supply terminal 1320 may become disconnected. To prevent power interruption due to the two terminals becoming disconnected, the pressure member 1800 may apply pressure to the protrusion 1350 of the battery 1300 in the insertion direction of the battery 1300.

[0147] Specifically, the pressurizing member 1800 may include: a contact portion 1810, including a second airflow hole 1800h for air movement and contacting the protrusion 1350; and an elastic portion 1820, disposed between the cover 1700 and the contact portion 1810, and used to press the contact portion 1810 toward the protrusion 1350.

[0148] When the cover 1700 is attached to the body 1100 in such a way that it covers the protrusion 1350 of the battery 1300, the elastic portion 1820 of the pressure member 1800 can be compressed between the cover 1700 and the contact portion 1810. Since the cover 1700 is supported and fixed by the body 1100, the elastic portion 1820 applies a spring force to the contact portion 1810 connected to the other end, with reference to the cover 1700 connected to one end thereto, so that the contact portion 1810 can press against the protrusion 1350.

[0149] Furthermore, the contact portion 1810 may be provided with more than one protrusion. The protrusion 1350 of the battery 1300 is provided with a groove capable of accommodating the protrusion of the contact portion 1810, so that the protrusion of the contact portion 1810 can be inserted into the groove of the protrusion 1350. Therefore, the protrusion 1310 can be supported by the contact portion 1810 without moving. The function of such a protrusion and groove is to prevent the protrusion 1310 from moving along the guide groove 1110 in the opposite direction of the engagement direction and separating from the body 1100.

[0150] According to the embodiment of the aerosol generating apparatus 1, the battery 1300 can be stably coupled by means of threaded connection simply by inserting the battery 1300 into the main body 1100 through a simple rotational movement.

[0151] Furthermore, according to the embodiment of the aerosol generating apparatus 1, the empty space between the battery 1300 and the main body 1100 can be used as an airflow channel 1500, thus eliminating the need to configure an additional airflow channel.

[0152] Figure 9 This is a block diagram of an aerosol generating apparatus according to yet another embodiment of the present disclosure.

[0153] The aerosol generating device 1 may include: a battery 11, a control unit 12, a sensor 13, an output unit 14, an input unit 15, a communication unit 16, a memory 17, and at least one heater 18, 24. However, the internal structure of the aerosol generating device 1 is not limited to... Figure 9 As shown. That is, based on the design of the aerosol generating device 1, those skilled in the art will understand that... Figure 9 A portion of the shown configuration can be omitted, or new configurations can be added.

[0154] Sensor 13 can detect the state of aerosol generating device 1 or the state around aerosol generating device 1, and transmit the detected information to control unit 12. Control unit 12 can control aerosol generating device 1 based on the detected information to perform various functions, such as controlling the operation of cartridge heater 24 and / or heater 18, restricting smoking, determining whether the cigarette holder S and / or cartridge 19 is inserted, and displaying notifications.

[0155] Sensor 13 may include at least one of the following: temperature sensor 131, suction sensor 132, insertion detection sensor 133, reuse detection sensor 134, cartridge detection sensor 135, cap detection sensor 136, and motion detection sensor 137.

[0156] Temperature sensor 131 can detect the temperature at which the cartridge heater 24 and / or heater 18 are heated. The aerosol generating device 1 includes a separate temperature sensor for detecting the temperature of the cartridge heater 24 and / or heater 18, or the cartridge heater 24 and / or heater 18 itself can be used as a temperature sensor.

[0157] Temperature sensor 131 can output a signal corresponding to the temperature of cartridge heater 24 and / or heater 18. For example, temperature sensor 131 may include a resistive element whose resistance value changes in response to temperature changes in cartridge heater 24 and / or heater 18. This can be implemented using a thermistor, which is a component that utilizes the property that its resistance changes in response to temperature. In this case, temperature sensor 131 can output a signal corresponding to the resistance value of the resistive element as a signal corresponding to the temperature of cartridge heater 24 and / or heater 18. For example, temperature sensor 131 can be constructed by a sensor that detects the resistance value of cartridge heater 24 and / or heater 18. In this case, temperature sensor 131 can output a signal corresponding to the resistance value of cartridge heater 24 and / or heater 18 as a signal corresponding to the temperature of cartridge heater 24 and / or heater 18.

[0158] Temperature sensor 131 can be configured around battery 11 to monitor the temperature of battery 11. Temperature sensor 131 can be configured adjacent to battery 11. For example, temperature sensor 131 can be attached to the side that serves as the power source for battery 11. For example, temperature sensor 131 can be mounted on one side of a printed circuit board.

[0159] Temperature sensor 131 can be configured inside the body 10 and detect the internal temperature of the body 10.

[0160] The suction sensor 132 can detect user suction based on various physical changes in the airflow channel. The suction sensor 132 can output a signal corresponding to suction. For example, the suction sensor 132 can be a pressure sensor. The suction sensor 132 can output a signal corresponding to the internal pressure of the aerosol generating device 1. Here, the internal pressure of the aerosol generating device 1 can correspond to the pressure of the gas flow channel. The suction sensor 132 can be configured corresponding to the gas flow channel in the aerosol generating device 1.

[0161] The insertion detection sensor 133 can detect the insertion and / or removal of the cigarette rod S. The insertion detection sensor 133 can detect signal changes corresponding to the insertion and / or removal of the cigarette rod S. The insertion detection sensor 133 can be disposed around the insertion space. The insertion detection sensor 133 can detect the insertion and / or removal of the cigarette rod S based on changes in the dielectric constant within the insertion space. For example, the insertion detection sensor 133 can be an inductive sensor and / or a capacitive sensor.

[0162] An inductive sensor may include at least one coil. The coil of the inductive sensor may be configured adjacent to the insertion space. For example, when the magnetic field around the coil in which the current flows may change, the characteristics of the current flowing in the coil may change according to Faraday's law of electromagnetic induction. Here, the characteristics of the current flowing in the coil may include the frequency, current value, voltage value, inductance value, impedance value, etc. of the alternating current.

[0163] An inductive sensor can output a signal corresponding to the characteristics of the current flowing in a coil. For example, an inductive sensor can output a signal corresponding to the inductance value of the coil.

[0164] A capacitive sensor may include a conductor. The conductor of the capacitive sensor may be configured adjacent to an insertion space. The capacitive sensor may output a signal corresponding to the surrounding electromagnetic characteristics (e.g., the capacitance around the conductor). For example, when a cigarette holder S comprising a wrapping paper of metallic material is inserted into the insertion space, the electromagnetic characteristics around the conductor may change due to the wrapping paper of the cigarette holder S.

[0165] The reuse detection sensor 134 can be used to detect whether the cigarette holder S is reusable. The reuse detection sensor 134 can be a color sensor. The color sensor can detect the color of the cigarette holder S. The color sensor can also detect the color of a portion of the packaging paper surrounding the cigarette holder S. The color sensor can detect values ​​related to the optical properties corresponding to the color of an object based on light reflected from the object. For example, the optical property could be the wavelength of light. The color sensor can be implemented as a single structural element together with a proximity sensor, or it can be implemented as a separate structural element distinct from the proximity sensor.

[0166] The color of at least a portion of the packaging paper constituting the cigarette holder S can be changed by aerosol. A detection sensor 134 can be configured to position corresponding to the location of at least a portion of the packaging paper whose color has changed due to aerosol when the cigarette holder S is inserted into the insertion space. For example, before the user uses the cigarette holder S, the color of at least a portion of the packaging paper may be a first color. At this time, as the aerosol generated by the aerosol generating device 1 passes through the cigarette holder S, the color of at least a portion of the packaging paper can change to a second color as it becomes wetted by the aerosol. On the other hand, the color of at least a portion of the packaging paper can remain the second color after changing from the first color to the second color.

[0167] The cartridge detection sensor 135 can detect the installation and / or removal of the cartridge 19. The cartridge detection sensor 135 can be implemented by an inductive sensor, a capacitive sensor, a resistive sensor, a Hall sensor (hall IC) utilizing the Hall effect, etc.

[0168] The cap detection sensor 136 can detect the installation and / or removal of the cap. When the cap is detached from the body 10, the cartridge 19 covered by the cap and a portion of the body 10 may be exposed to the outside. The cap detection sensor 136 can be implemented by a contact sensor, a Hall sensor (hall IC), an optical sensor, etc.

[0169] The motion detection sensor 137 can detect the motion of the aerosol generating device. The motion detection sensor 137 can be implemented by at least one of an accelerometer and a gyroscope.

[0170] In addition to the aforementioned sensors (131 to 137), sensor 13 may also include at least one of a humidity sensor, a barometric pressure sensor, a magnetic sensor, a GPS sensor, and a proximity sensor. Since a person skilled in the art can intuitively infer the function of each sensor from its name, a detailed description is unnecessary.

[0171] The output unit 14 can output information related to the state of the aerosol generating device 1 and provide it to the user. The output unit 14 may include, but is not limited to, at least one of the display 141, the tactile unit 142, and the audio output unit 143. When the display 141 and the touchpad are arranged in a layered structure and constitute a touch screen, the display 141 can be used as an input device in addition to being used as an output device.

[0172] Display 141 can visually provide the user with information related to the aerosol generating device 1. For example, the information related to the aerosol generating device 1 may include various information such as the charging / discharging status of the battery 11, the preheating status of the heater 18, the insertion / removal status of the e-cigarette S and / or the cartridge 19, the installation / removal status of the cap, or the status of restrictions on the use of the aerosol generating device 1 (e.g., abnormal item detection). Display 141 can output this information externally. For example, display 141 may be in the form of an LED light-emitting element. For example, display 141 may be a liquid crystal display (LCD), an organic light-emitting display (OLED), etc.

[0173] The tactile unit 142 can convert electrical signals into mechanical or electrical stimulation, thereby providing the user with information related to the aerosol generating device 1 in a tactile manner. For example, during the initial power supply setting time to the cartridge heater 24 and / or heater 18, the tactile unit 142 can generate vibrations corresponding to the completion of the initial preheating. The tactile unit 142 may include a vibration motor, a piezoelectric element, or an electrical stimulation device.

[0174] The audio output unit 143 can provide users with information related to the aerosol generating device 1 in an auditory manner. For example, the audio output unit 143 can convert electrical signals into audio signals and output them to the outside.

[0175] Battery 11 can supply the power required for the operation of aerosol generating device 1. Battery 11 can supply power for heating the cartridge heater 24 and / or heater 18. In addition, battery 11 can supply the power required for the operation of other structural components (sensor 13, output unit 14, input unit 15, communication unit 16, and memory 17) provided within aerosol generating device 1. Battery 11 can be a rechargeable power source or a disposable power source. For example, battery 11 can be a lithium polymer (LiPoly) power source, but is not limited thereto.

[0176] The battery 11 can be a removable (detachable, separate) power source. The battery 11 is provided with electrical contacts, which, when installed in the aerosol generating device 1, are electrically connected to the electrical contacts provided in the aerosol generating device 1, thereby enabling the supply of power to the aerosol generating device 1. Alternatively, the battery 11 can also be provided with a charging coil instead of separate electrical contacts, thereby supplying power to the aerosol generating device 1 via wireless charging. In other words, the power supply method of the battery 11 can be diversified, and the electrical connection method between the battery 11 and the aerosol generating device 1 can be changed depending on the power supply method supported by the battery 11.

[0177] The removable battery 11 may be provided with a charger interface that can be connected to an external charger.

[0192] The control unit 12 can control the overall operation of the aerosol generating device 1. In one embodiment, the control unit 12 may include at least one processor. The processor may be implemented by a plurality of logic gate arrays, or by a combination of a general-purpose microprocessor and a memory storing programs that can be executed by the microprocessor. In addition, as will be understood by those skilled in the art to which this embodiment pertains, it may also be implemented by other forms of hardware.

[0193] The control unit 12 can control the temperature of the heater 18 by controlling the power supplied to the heater 18 from the battery 11. The control unit 12 can control the temperature of the cartridge heater 24 and / or the heater 18 based on the temperature sensed by the temperature sensor 131. The control unit 12 can adjust the power supplied to the cartridge heater 24 and / or the heater 18 based on the temperature. For example, the control unit 12 can determine the target temperature of the cartridge heater 24 and / or the heater 18 based on the temperature distribution stored in the memory 17.

[0194] The aerosol generating device 1 may include a power supply circuit (not shown) electrically connected to the battery 11 between the battery 11 and the cartridge heater 24 and / or heater 18. The power supply circuit may be electrically connected to the cartridge heater 24, heater 18, or induction coil (not shown). The power supply circuit may include at least one switching element. The switching element may be implemented using a bipolar junction transistor (BJT), a field-effect transistor (FET), or the like. The control unit 12 may control the power supply circuit.

[0195] The control unit 12 can control the power supply by controlling the switching of the switching elements in the power supply circuit. The power supply circuit can be an inverter that converts the DC power output from the battery 11 into AC power. For example, the inverter can be composed of a full-bridge circuit or a half-bridge circuit that includes multiple switching elements.

[0196] The control unit 12 can turn on the switching element to supply power from the battery 11 to the cartridge heater 24 and / or the heater 18. The control unit 12 can turn off the switching element to cut off the power supply to the cartridge heater 24 and / or the heater 18. The control unit 12 can regulate the current supplied from the battery 11 by adjusting the frequency and / or duty cycle of the current pulses input to the switching element.

[0197] The control unit 12 can control the voltage output by the battery 11 by controlling the switching of the switching elements in the power supply circuit. The power conversion circuit can convert the voltage output by the battery 11. For example, the power conversion circuit can include a buck converter that reduces the voltage output by the battery 11. For example, the power conversion circuit can be implemented using a buck-boost converter, a Zener diode, etc.

[0198] The control unit 12 can adjust the voltage level output by the power conversion circuit by controlling the on / off operation of the switching elements included in the power conversion circuit. When the switching element remains in the closed (on) state, the voltage level output by the power conversion circuit can correspond to the voltage level output by the battery 11. The duty cycle of the on / off operation of the switching element can correspond to the ratio of the voltage output by the power conversion circuit to the voltage output by the battery 11. As the duty cycle of the on / off operation of the switching element decreases, the voltage level output by the power conversion circuit can decrease. The heater 18 can be heated based on the voltage output by the power conversion circuit.

[0199] The control unit 12 can control the power supplied to the heater 18 by using at least one of pulse width modulation (PWM) and proportional-integral-differential (PID) methods.

[0200] For example, the control unit 12 can use PWM to control the supply of current pulses with a specified frequency and duty cycle to the heater 18. The control unit 12 can control the power supplied to the heater 18 by adjusting the frequency and duty cycle of the current pulses.

[0201] For example, the control unit 12 can determine the target temperature as the object to be controlled based on the temperature distribution. The control unit 12 can use a PID method to control the power supplied to the heater 18, which is a feedback control method based on the difference between the temperature of the heater 18 and the target temperature, the value of integrating the difference over time, and the value of differentiating the difference over time.

[0202] The control unit 12 can prevent the cartridge heater 24 and / or heater 18 from overheating. For example, the control unit 12 can control the operation of the power conversion circuit to interrupt the power supplied to the cartridge heater 24 and / or heater 18 based on the temperature of the cartridge heater 24 and / or heater 18 exceeding a preset limit temperature. For example, the control unit 12 can reduce the power supplied to the cartridge heater 24 and / or heater 18 by a certain ratio based on the temperature of the cartridge heater 24 and / or heater 18 exceeding a preset limit temperature. For example, the control unit 12 can determine that the aerosol generating material contained in the cartridge 19 has been depleted based on the temperature of the cartridge heater 24 exceeding the limit temperature, and cut off the power supplied to the cartridge heater 24.

[0203] The control unit 12 can control the charging and discharging of the battery 11. The control unit 12 can determine the temperature of the battery 11 based on the output signal of the temperature sensor 131.

[0204] When the power line is connected to the power terminal of the aerosol generating device 1, the control unit 12 can check whether the temperature of the battery 11 is above a first limit temperature, which is the reference for cutting off the charging of the battery 11. If the temperature of the battery 11 is below the first limit temperature, the control unit 12 can control the battery 11 to charge based on a preset charging current. If the temperature of the battery 11 is above the first limit temperature, the control unit 12 can cut off the charging of the battery 11.

[0205] When the aerosol generating device 1 is powered on, the control unit 12 can check whether the temperature of the battery 11 is above a second limit temperature, which is the reference for cutting off the discharge of the battery 11.

If the temperature of the battery 11 is above the second limit temperature, the control unit 12 can interrupt the use of the power stored in the battery 11.

[0206] The control unit 12 can calculate the remaining capacity of the power stored in the battery 11. For example, the control unit 12 can calculate the remaining capacity of the battery 11 based on the voltage and / or current sensing values ​​of the battery 11.

[0207] The control unit 12 can determine whether the cigarette device S is inserted into the insertion space by using the insertion detection sensor 133.

For example, the control unit 12 can supply power to the cartridge heater 24 and / or the heater 18 based on the temperature distribution stored in the memory 17.

[0208] The control unit 12 can determine whether the tobacco stick S has been removed from the insertion space. For example, the control unit 12 can determine whether the tobacco stick S has been removed from the insertion space by using the insertion detection sensor 133. For example, if the temperature of the heater 18 is above the limit temperature or the temperature change slope of the heater 18 is above the set slope, the control unit 12 can determine that the tobacco stick S has been removed from the insertion space. If it is determined that the tobacco stick S has been removed from the insertion space, the control unit 12 can cut off the power supply to the tobacco cartridge heater 24 and / or the heater 18.

[0209] The control unit 12 can control the power supply time and / or power supply amount to the heater 18 based on the state of the pipe S detected by the sensor 13.

The control unit 12 can determine the moisture content of the pipe S based on the confirmed level range.

[0210] When the smoke rod S is in an over-wet state, the control unit 12 can control the power supply time to the heater 18, thereby increasing the preheating time of the smoke rod S compared to the normal state.

[0211] The control unit 12 can determine whether the e-cigarette S inserted into the insertion space is being reused by using the reuse detection sensor 134. For example, the control unit 12 can compare the sensing value of the reuse detection sensor signal with a first reference range including the first color. If the sensing value is within the first reference range, it can be determined that the e-cigarette S is not being used. For example, the control unit 12 can compare the sensing value of the reuse detection sensor signal with a second reference range including the second color. If the sensing value is within the second reference range, it can be determined that the e-cigarette S is being used. If it is determined that the e-cigarette S is being used, the control unit 12 can cut off the power supply to the cartridge heater 24 and / or the heater 18.

[0213] The control unit 12 can determine whether the aerosol-generating material of the cartridge 19 has been depleted. For example, the control unit 12 preheats the cartridge heater 24 and / or heater 18 by applying electricity, and determines whether the temperature of the cartridge heater 24 exceeds the limit temperature during the preheating period. If the temperature of the cartridge heater 24 exceeds the limit temperature, it can be determined that the aerosol-generating material of the cartridge 19 has been depleted. If it is determined that the aerosol-generating material of the cartridge 19 has been depleted, the control unit 12 can cut off the power supply to the cartridge heater 24 and / or heater 18.

[0214] The control unit 12 can determine whether the cartridge 19 can be used. For example, based on the data stored in the memory 17, if the current number of puffs is greater than or equal to the maximum number of puffs set for the cartridge 19, the control unit 12 can determine that the cartridge 19 cannot be used. For example, if the total heating time of the cartridge heater 24 is greater than or equal to the preset maximum time, or if the total electrical power supplied to the cartridge heater 24 is greater than or equal to the preset maximum electrical power, the control unit 12 can determine that the cartridge 19 cannot be used.

[0215] The control unit 12 can determine the user's inhalation through the inhalation sensor 132. For example, the control unit 12 can determine whether an inhalation has occurred based on the sensing value of the signal from the inhalation sensor 132. For example, the control unit 12 can determine the inhalation intensity based on the sensing value of the signal from the inhalation sensor 132. If the number of inhalations reaches a preset maximum number of inhalations, or if no inhalation is detected for a preset time, the control unit 12 can cut off the power supply to the cartridge heater 24 and / or the heater 18.

[0216] The control unit 12 can determine whether the cap is engaged and / or removed by the cap detection sensor 136. For example, the control unit 12 can determine whether the cap is engaged and / or removed based on the sensed value of the signal from the cap detection sensor.
