[0033] Regarding the terminology used to describe various embodiments, currently widely used and common terms are selected in consideration of the function of the structural elements in the various embodiments of the invention. However, the meaning of terms may be changed based on intent, precedent, the emergence of new technologies, etc. Additionally, in some cases, less commonly used terms may be chosen. In such cases, the meaning of the term will be described in detail in the corresponding section of the description of the invention. Therefore, the terms used in the various embodiments of the invention should be defined based on their meanings and the description provided herein.

The shape, size, material, and structure of an aerosol-generating article may vary depending on the embodiment. Examples of aerosol-generating articles may include, but are not limited to, cigarette-shaped substrates and cartridges. Hereinafter, the term "cigarette" (i.e., used alone without modifiers such as "general," "conventional," or "combustible") can refer to an aerosol-generating article having a similar shape to a conventional combustible cigarette.

[0038] The present invention will now be described in more detail with reference to the accompanying drawings, which illustrate exemplary embodiments of the invention to enable those skilled in the art to readily implement it. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments described herein.

[0041] Throughout the specification, the “longitudinal direction” of a component may refer to the direction in which the component extends along one of its axes, and the one axis of the component may indicate a direction in which the length of the component extending along that one axis is longer than the length of the component extending along another axis transverse to that one axis.

[0042] Figure 1A This is a cross-sectional view of one aspect of an aerosol generating apparatus 100 according to one embodiment. Figure 1B This is a cross-sectional view of another aspect of an aerosol generating apparatus 100 according to one embodiment;

[0043] Reference Figure 1A and Figure 1B This will be explained in more detail one aspect and the other aspect of the aerosol generating device 100 based on the movement of the cover 110.

[0044] One embodiment of the aerosol generating apparatus 100 can generate aerosols by heating the aerosol generating article 200.

[0045] Aerosol-generating article 200 may contain tobacco substances and / or aerosol-generating substances.

[0046] Tobacco substances can be made from tobacco sheets or shredded tobacco. Alternatively, they can be made from tobacco leaves cut into thin sheets. Tobacco substances may contain nicotine. They can also be solids or liquids containing tobacco extracts.

[0047] For example, aerosol-generating substances may include at least one of glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol, but are not limited thereto.

[0048] The aerosol generating apparatus 100 may include a cover 110 having an opening 111. The aerosol generating apparatus 100 may include a body 130 having a receiving portion 120 for receiving an aerosol generating article 200 inserted through the opening 111. The cover 110 and the body 130 may be joined together to form the external shape of the aerosol generating apparatus 100.

[0049] The aerosol generating article 200 can be inserted into the receiving portion 120 of the main body 130 through the opening 111 of the cover 110. The cover 110 can be attached to one side of the main body 130. The cover 110 and the main body 130 can be detachably attached to each other, and when using the aerosol generating device 100, the user can hold the cover 110 and the main body 130, which are attached as one piece.

[0050] The receiving portion 120 may be formed along the length direction (i.e., longitudinal direction) of the aerosol generating apparatus 100. The aerosol generating article 200 and the receiving portion 120 may have corresponding shapes. For example, when the aerosol generating article 200 has a cylindrical shape, the receiving portion 120 may also have a cylindrical shape to receive the aerosol generating article 200. However, the shapes of the aerosol generating article 200 and the receiving portion 120 are not limited to this and may be changed as needed.

[0051] The aerosol generating apparatus 100 may include a heater 140 for heating the aerosol generating article 200 housed in the housing 120. The heater 140 may be arranged in the housing 120 of the main body 130.

[0052] Heater 140 may include a resistance heater. For example, heater 140 may include a conductive rail, so that heater 140 can be heated when current flows through the conductive rail. However, heater 140 is not limited to the above examples and may include all heaters capable of being heated to a desired temperature. The desired temperature may be preset in the aerosol generating apparatus 100 or may be set by the user.

[0053] In another example, heater 140 may include an induction heater. Specifically, heater 140 may include a conductive coil for induction heating of aerosol generating article 200, which may include a heat-sensitive element that can be heated by the induction heater.

[0054] exist Figure 1A and Figure 1B In this device, the heater 140 has a needle-like shape and is arranged in the housing 120 of the aerosol generating device 100 along the longitudinal axis of the aerosol generating device 100. However, the shape and arrangement of the heater 140 are not limited to this.

[0055] For example, heater 140 may include tubular heating elements, plate heating elements, needle heating elements, or rod heating elements, and may heat the interior or exterior of aerosol generating article 200 depending on the shape of the heating elements.

[0056] Additionally, the aerosol generating apparatus 100 may include a plurality of heaters 140. These heaters 140 may be inserted inside the aerosol generating article 200 or disposed outside the aerosol generating article 200. Alternatively, some of the heaters 140 may be inserted inside the aerosol generating article 200, while others may be disposed outside the aerosol generating article 200. Furthermore, the shape of the heaters 140 is not limited to... Figure 1A and Figure 1B The shape shown can be made into various shapes.

[0057] The aerosol generating device 100 may include a processor 170 and a battery 180.

[0058] The battery 180 can supply the power required for the operation of the aerosol generating apparatus 100. For example, the battery 180 can supply power to heat the heater 140, which transfers heat to the aerosol generating article 200. In addition, the battery 180 can supply the power required for operation to the display (not shown), vibrating unit (not shown), and other components provided in the aerosol generating apparatus 100.

[0059] The processor 170 can control the operation of the aerosol generating device 100 as a whole. Specifically, the processor 170 can operate the aerosol generating device 100 by controlling the battery 180. The processor 170 can control the operation of other components included in the aerosol generating device 100. In addition, the processor 170 can check the status of each component of the aerosol generating device 100 to determine whether the aerosol generating device 100 is in an operable state.

[0060] Processor 170 may include at least one processor. Processor 170 may be implemented by an array of multiple logic gates, or by a combination of a general-purpose microprocessor and a memory storing a program that can be executed in the microprocessor. Those skilled in the art will understand that processor 170 may be implemented in other hardware forms.

[0061] The aerosol generating apparatus 100 may include an extractor 150 for extracting the aerosol generating article 200 from the containment 120.

[0062] The extractor 150 can be configured to easily extract the aerosol-generated article 200 from the aerosol-generating device 100. For example, the extractor 150 can be detachably mounted in the receiving portion 120 of the aerosol-generating device 100, and the extractor 150 can move within or detach from the receiving portion 120. Therefore, the aerosol-generated article 200 can be removed from the aerosol-generating device 100.

[0063] The extractor 150 may include a cavity for accommodating the aerosol generating article 200. That is, when the aerosol generating article 200 is accommodated in the accommodating portion 120 of the aerosol generating device 100, the aerosol generating article 200 may be located in the cavity of the extractor 150 installed in the accommodating portion 120.

[0064] The cavity of the extractor 150 may have a size and shape corresponding to these aerosol generating articles 200. For example, when the aerosol generating article 200 has a cylindrical shape such as a cigarette, the cavity of the extractor 150 may have a shape and size capable of accommodating a cigarette.

[0065] The shape and size of the cavity of the extractor 150 can be appropriately determined to ensure close contact between the extractor 150 and the aerosol-generating article 200. Therefore, the aerosol-generating article 200 can be removed from the aerosol-generating device 100 by using the extractor 150. The shape and size of the extractor 150 are not limited to those shown in the accompanying drawings.

[0066] A through-hole for the heater 140 to pass through can be formed on the lower surface of the extractor 150. Therefore, when the extractor 150 is detached from the aerosol generating apparatus 100, the heater 140 can pass through the through-hole on the lower surface of the extractor 150 and be located within the cavity of the extractor 150. The heater 140 can effectively heat the aerosol generating article 200 by contacting it with the aerosol generating article 200 housed within the cavity of the extractor 150.

[0067] The extractor 150 can be integrally formed with the cover 110, thereby extending the extractor 150 from the cover 110. When the cover 110 is engaged with the body 130, the extractor 150 can be inserted into the receiving portion 120. Fixing portions for securing the cover 110 to the body 130 can be formed in the extractor 150 and the receiving portion 120, respectively.

[0068] For example, a protrusion (not shown) may be formed on the outer surface of the extractor 150, and a recess (not shown) may be formed on the receiving portion 120. In this case, when the cover 110 is engaged with the body 130, the protrusion formed on the outer surface of the extractor 150 can be inserted into the recess of the receiving portion 120. Therefore, the cover 110 can be fixed to the body 130.

[0069] As needed, the connection between the cover 110 and the body 130 can be released, and the cover 110 can move relative to the body 130.

[0070] Since the cap 110 and the extractor 150 are integrally formed, the extractor 150 can also move according to the movement of the cap 110. For example, the cap 110 and the extractor 150 can move relative to the main body 130 in the longitudinal direction of the receiving portion 120. As the extractor 150 moves in the longitudinal direction of the receiving portion 120, the aerosol generating article 200 contained in the receiving portion 120 can be extracted.

[0071] The aerosol generating apparatus 100 may include a driver 160 for moving the cover 110. In this case, the processor 170 may control the driver 160 to move the cover 110. The processor 170 may control the driver 160 after power supply to the heater 140 has stopped.

[0072] The actuator 160 may include a first actuator 160a disposed in the body 130 and a second actuator 160b disposed in the cover 110. The first actuator 160a and the second actuator 160b may interact to move the cover 110.

[0073] For example, processor 170 can control the power supply to driver 160 using battery 180. Processor 170 can control driver 160 to move cover 110 away from body 130. Alternatively, processor 170 can control driver 160 to move cover towards body 130.

[0074] The actuator 160 can be arranged parallel to the receiving portion 120. That is, the actuator 160 can be arranged radially spaced from the longitudinal central axis of the receiving portion 120. For example, the first actuator 160a arranged in the main body 130 can be radially spaced from the longitudinal central axis of the receiving portion 120. The second actuator 160b can be arranged in the cover portion 110 at a position corresponding to the position of the first actuator 160a.

[0075] Figure 1A and Figure 1B The first driver 160a and the second driver 160b shown are separate components; however, the first driver 160a and the second driver 160b can be combined into a single component.

[0076] Figures 2A to 2D This is a diagram showing various examples of the actuator 160 for moving the extractor 150 integrally formed with the cover 110. (Refer to...) Figures 2A to 2D The mechanism by which the drive 160 moves the cover 110 will be explained in more detail.

[0077] Reference Figure 2A The first driver 160a of the driver 160 can be an electromagnet, and the second driver 160b can be a magnet that interacts with the electromagnet. The processor 170 can move the cover 110 by controlling the power supply from the battery 180 to the electromagnet.

[0078] For example, processor 170 can apply a repulsive force that causes first driver 160a and second driver 160b to push each other by controlling the power supply to the electromagnet (i.e., first driver 160a). That is, processor 170 can control the direction of the current so that the end of the electromagnet closest to the magnet has the same magnetic poles as the magnet. Therefore, a repulsive force can be generated between the electromagnet and the magnet.

[0079] Through this repulsive force, the cover 110 can move away from the main body 130, and the extractor 150 connected to the cover 110 can also move away from the bottom of the receiving portion 120. In this case, the extractor 150 can extract the aerosol-generating article 200 contained in the receiving portion 120.

[0080] Additionally, the processor 170 can apply an attractive force that causes the first driver 160a and the second driver 160b to attract each other by controlling the power supply to the electromagnet (i.e., the first driver 160a). That is, the processor 170 can control the direction of the current so that the end of the electromagnet closest to the magnet has a magnetic pole different from the magnetic pole of the magnet. Therefore, an attractive force can be generated between the first driver 160a and the second driver 160b.

[0081] Through this attraction, the cover 110 can move toward the body 130, and the extractor 150 connected to the cover 110 can also move toward the bottom of the receiving portion 120.

[0082] Reference Figure 2B The first driver 160a of the driver 160 can be a motor, and the second driver 160b can be a gear connected to the motor. In this case, one end of the gear can be connected to the motor, and the other end of the gear can be connected to the cover 110. The processor 170 can control the power supply to the motor using the battery 180, thereby moving the cover 110.

[0083] For example, processor 170 supplies power to a motor acting as a first driver 160a, thereby controlling the motor to move a gear (i.e., a second driver 160b), causing the cover 110 to move away from the body 130. Figure 2B In this configuration, the end of the gear connected to the motor can be moved upwards. Therefore, the other end of the gear connected to the cover 110 can apply force to the cover 110, causing the cover 110 to move away from the body 130.

[0084] The cover 110 can be moved away from the main body 130 by the action of gears, and the extractor 150 connected to the cover 110 can be moved away from the bottom of the receiving portion 120. Therefore, the extractor 150 can extract the aerosol generating article 200 contained in the receiving portion 120.

[0085] Additionally, the processor 170 supplies power to the motor acting as the first driver 160a, thereby controlling the motor to move the gear (i.e., the second driver 160b), causing the cover 110 to move towards the body 130. Figure 2B In this configuration, the end of the gear connected to the motor can be moved downwards. Therefore, the other end of the gear connected to the cover 110 can apply force to the cover 110, causing the cover 110 to move toward the body 130.

[0086] Therefore, the extractor 150 connected to the cover 110 can also move in a direction closer to the bottom of the receiving portion 120.

[0087] Reference Figure 2C and Figure 2D The first driver 160a of the driver 160 may be a protrusion, and the second driver 160b of the driver 160 may be the bottom of the cover 110 that contacts the protrusion. In this case, the protrusion can move the cover 110 by pressing the bottom of the cover 110.

[0088] For example, such as Figure 2C As shown, under the control of the processor 170, the protrusion can move closer to the bottom of the receiving portion 120. As the protrusion moves closer to the receiving portion 120 in the horizontal direction (i.e., in a direction perpendicular to the longitudinal direction of the receiving portion 120), the bottom of the cover portion 110 can be pressed (i.e., pushed) by the protrusion. Therefore, the cover portion 110 can move away from the body 130.

[0089] As the cover 110 moves away from the main body 130, the extractor 150 connected to the cover 110 can also move away from the bottom of the receiving portion 120. Therefore, the extractor 150 can extract the aerosol-generating article 200 contained in the receiving portion 120.

[0090] On the other hand, the protrusion can be moved away from the receiving portion 120. The processor 170 can control the protrusion to move away from the receiving portion 120. When the protrusion is received in the groove formed at the bottom of the cover portion 110, the pressure on the protrusion can be removed, and the cover portion 110 can be moved closer to the body 130.

[0091] As the cover 110 moves closer to the body 130, the extractor 150 connected to the cover 110 can also move closer to the bottom of the receiving portion 120.

[0092] As another example, such as Figure 2D As shown, the protrusion can be rotated to press the bottom of the cover 110. The processor 170 can control the protrusion to rotate about a rotation axis perpendicular to the longitudinal direction of the receiving portion 120.

[0093] The protrusion can be rotated to face the bottom of the cover 110. When the protrusion is rotated to contact the bottom of the cover 110, the bottom of the cover 110 can be pressed by the protrusion. As the bottom of the cover 110 is pressed, the cover 110 can also be pressed. In this case, the cover 110 can move away from the body 130.

[0094] As the cover 110 moves away from the main body 130, the extractor 150 connected to the cover 110 can also move away from the bottom of the receiving portion 120. Therefore, the extractor 150 can extract the aerosol-generating article 200 contained in the receiving portion 120.

[0095] Additionally, the protrusion can rotate in a direction away from the bottom of the cover 110. As the protrusion rotates and is positioned in the groove formed in the body 130, the pressure on the protrusion can be removed, and the cover 110 can move closer to the body 130.

[0096] As the cover 110 moves closer to the body 130, the extractor 150 connected to the cover 110 can also move closer to the bottom of the receiving portion 120.

[0097] Although not shown in the figure, as another example, an actuator including a shape memory alloy can be arranged between the cover 110 and the body 130. The shape memory alloy can be preset to have a specific shape according to the supply of current, and the specific shape can be changed according to purpose and need.

[0098] When an electric current is supplied to the actuator, which includes a shape memory alloy, the actuator can deform to separate the cover 100 from the body 130. For example, the length and / or volume of the actuator can increase depending on the supply of current, so that the cover 110 can separate from the body 130.

[0099] As the actuator, including a shape memory alloy, separates the cover 110 from the body 130, the cover 110 can move away from the body 130. The extractor 150, connected to the cover 110, can also move away from the bottom of the receiving portion 120, thereby extracting the aerosol-generating article 200 contained in the receiving portion 120. The aerosol-generating apparatus 100 according to the described embodiment can be applied to other embodiments, and the same reference numerals hereinafter can denote components that are substantially the same as those described.

[0100] Figure 3 This is a cross-sectional view of an aerosol generating apparatus 100 according to another embodiment.

[0101] The aerosol generating device 100 may include a sensor 190. The sensor 190 may be electrically connected to the processor 170.

[0102] After power supply to heater 140 is stopped, processor 170 can control driver 160. For example, the cessation of power supply to heater 140 can be detected based on the number of puffs and / or total smoking time of the user.

[0103] Specifically, when at least one of the number of puffs or the total smoking time exceeds a preset threshold, the processor 170 can confirm that the power supply to the heater 140 has stopped.

[0104] When it is confirmed that the power supply to the heater 140 has stopped, the processor 170 can control the driver 160 to move the cover 110 away from the body 130. As the cover 110 moves away from the body 130, the extractor 150 connected to the cover 110 can move within the receiving portion 120. That is, the extractor 150 can move away from the bottom of the receiving portion 120 and extract the aerosol-generating article 200 contained in the receiving portion 120.

[0105] As another example, the cessation of power supply to heater 140 can be detected based on the insertion or removal of aerosol-generated items.

[0106] Sensor 190 may be a detection sensor for detecting the insertion or discharge of aerosol-generating article 200. The detection sensor may include at least one of a pressure sensor, a light sensor, an infrared sensor, an inductive sensor, a capacitive sensor, a resistive sensor, and a geomagnetic sensor.

[0107] For example, the detection sensor can be an inductive sensor. The inductive sensor can detect the insertion and discharge of the aerosol generating article 200 based on the inductance change of the receiving portion 120 according to the insertion and discharge of the aerosol generating article 200.

[0108] As another example, the detection sensor can be a pressure sensor. When the aerosol generating article 200 is inserted into or discharged from the receiving portion 120, the pressure sensor can detect the pressure applied to the side wall or lower wall of the receiving portion 120, and the pressure sensor can detect the insertion and discharge of the aerosol generating article 200 based on the pressure changes in the receiving portion 120.

[0109] The processor 170 can control the driver 160 based on the insertion and discharge of the aerosol-generating article 200 detected by the detection sensor.

[0110] When the detection sensor detects the discharge of aerosol-generating article 200, the processor 170 can control the driver 160 to move the cover 110 away from the body 130. As the cover 110 moves away from the body 130, the extractor 150 connected to the cover 110 can move in the same direction. That is, the extractor 150 can move away from the bottom of the container 120 and extract the aerosol-generating article 200 contained in the container 120.

[0111] When the detection sensor detects the insertion of the aerosol-generating article 200, the processor 170 can control the driver 160 to move the cover 110 toward the body 130. As the cover 110 moves closer to the body 130, the extractor 150 connected to the cover 110 can move in the same direction. That is, the extractor 150 can move toward the bottom of the receiving portion 120.

[0112] Figure 4 This is a cross-sectional view of an aerosol generating apparatus 100 according to yet another embodiment.

[0113] like Figure 4 As shown, the aerosol generating device 100 may include a sealing part 125, which is arranged at the lower end of the receiving part 120 to prevent leakage.

[0114] When the aerosol generating article 200 is heated, the atomized aerosol can be liquefied again to form droplets. In this case, the droplets can accumulate at the bottom of the container 120. The sealing part 125 can cover the lower end of the container 120 to prevent droplets from leaking from the lower end of the container 120 into the body 130. When the cover 110 is attached to the body 130, the sealing part 125 can be arranged at the lower end of the extractor 150. The sealing part 125 can prevent droplets or residues that may be discharged from the extractor 150 from leaking into the body 130.

[0115] The sealing portion 125 may have a shape and size corresponding to the receiving portion 120. That is, the sealing portion 125 and the receiving portion 120 may have substantially the same horizontal cross section, and the sealing portion 125 may be arranged at the bottom of the receiving portion 120 by fitting together.

[0116] The sealing portion 125 may include an elastic material. For example, the elastic material may be rubber or silicone. Because the sealing portion 125 includes an elastic material, it can tightly seal the lower end of the receiving portion 120.

[0117] Figure 5 This is a cross-sectional view of an aerosol generating apparatus 100 according to another embodiment.

[0118] like Figure 5 As shown, the cover 110 can be separated from the body 130. Therefore, the extractor 150, which is integrally formed with the cover 110, can also be separated from the body 130.

[0119] After separating the cover 110 and extractor 150 from the main body 130, the user can clean the cover 110 and extractor 150 using air or water. Furthermore, the cover 110 and extractor 150 can be replaced as needed. That is, the cover 110 and extractor 150 can be replaced as consumables. Because the cover 110 and extractor 150 are easy to clean and replace, they can be kept in a clean and hygienic state.

[0120] The aerosol generating apparatus 100 according to an embodiment may include a cover 110 and an extractor 150 integrally formed with the cover 110. Since the extractor 150 is integrally formed with the cover 110, the extractor 150 can move together with the cover 110.

[0121] The embodiment may also include an actuator 160 for moving the cover 110. That is, the actuator 160 can move the cover 110, and as the cover 110 moves, the extractor 150 can extract the aerosol-generating article 200. Therefore, the actuator 160 for moving the cover 110 can be arranged at a position corresponding to the cover 110, thus the components of the aerosol-generating device 100 can be effectively arranged within the aerosol-generating device 100.

[0122] Those skilled in the art to which the embodiments of the present invention pertain will understand that these embodiments can be implemented in modified forms without departing from the basic features described above. The disclosed methods should be considered illustrative only, not restrictive. The scope of the invention is shown in the claims, not in the description above, and all differences within the scope of equivalents should be interpreted as included in the invention.
