[0001] The present disclosure relates to an aerosol generating device.

[0002] An aerosol generator is designed to extract a specific component from a medium or substance through an aerosol. The medium may contain various components. The components contained in the medium may include various flavoring substances. For example, the components contained in the medium may include nicotine, herbal ingredients, and / or coffee ingredients. Recently, extensive research has been conducted on such aerosol generators.

[0003] In an aerosol generating device into which a stick is inserted, a cap for opening and closing the insertion port of the stick may be provided. In conventional aerosol generating devices, a structure utilizing a spring or magnet, etc., is used to allow the sliding movement of the cap. However, structures utilizing a spring or magnet, etc., have the problem of being complex in structure and increasing the volume of the device.

[0004] The present disclosure aims to solve the above-mentioned and other problems.

[0005] Another object may be to provide an aerosol generating device having a guide rail comprising a protrusion protruding on a sliding path of a cap for opening and closing an insertion port and an extension inclined thereto.

[0006] Another object may be to provide an aerosol generating device in which movement of the cap is guided by the elastic restoring force of the guide rail.

[0007] Another purpose may be to provide an aerosol generating device in which rails supporting the upper and lower sides of the cap are inclined in the longitudinal direction to guide movement of the cap.

[0008] Another object may be to provide an aerosol generating device having a protrusion and a stopper for securing a slider of the cap in each of a position where the cap closes the insertion port and a position where the cap opens the insertion port.

[0009] Another object may be to provide an aerosol generating device having a rib spaced apart from the guide rail and protruding upwardly and extending in the longitudinal direction of the guide rail.

[0011] According to at least one embodiment of the present disclosure, a guide rail is provided, which comprises a protrusion protruding on a sliding path of a cap for opening and closing an insertion port and an extension inclined thereto, thereby simplifying the sliding guide structure of the cap.

[0012] According to at least one embodiment of the present disclosure, movement of the cap is guided by the elastic restoring force of the guide rail, so that structures such as springs or magnets can be omitted, and the volume of the device can be reduced.

[0013] According to at least one embodiment of the present disclosure, the rails supporting the upper and lower sides of the cap are inclined in the longitudinal direction to guide the movement of the cap, thereby improving the usability related to the opening and closing operation of the cap.

[0014] According to at least one embodiment of the present disclosure, the cap has a protrusion and a stopper for fixing a slider of the cap in each of a position where the insertion port is closed and a position where the insertion port is opened, so that the position of the cap can be fixed and the cap can be prevented from shaking when the insertion port is closed or opened.

[0015] According to at least one embodiment of the present disclosure, a rib is provided that is spaced apart from the guide rail and protrudes upwardly and extends in the longitudinal direction of the guide rail, thereby minimizing foreign matter from entering the device through a structure for sliding the cap.

The angle formed by the second inclined surface (515) with the longitudinal direction of the plate (50) may be greater than the angle formed by the second extension (512) with the longitudinal direction of the plate (50).

[0085] The support surface (516) can connect the first inclined surface (514) and the second inclined surface (515). The support surface (516) can extend flatly along the length of the plate (50) or protrude convexly upward.

[0086] The slider (43) is arranged on the plate rail (51) and can move along the plate rail (51). The slider (43) can move along the first extension (511), the protrusion (513), and the second extension (512). The slider (43) can be arranged on the first extension (511) at a first position where the cap (40) closes the insertion port (54). The slider (43) can be arranged on the second extension (512) at a second position where the cap (40) opens the insertion port (54).

[0087]

[0088] FIGS. 10 to 13 are cross-sectional views showing the combined structure of a cap and a guide rail according to the sliding movement of the cap in an aerosol generating device according to one embodiment of the present disclosure.

[0089] Referring to FIG. 10, the guide rails (314, 51) may include a case rail (314) that covers the upper side of the slider (43) of the cap (40) and a plate rail (51) that supports the lower side of the slider (43). A space or path along which the cap (40) can move may be formed between the case rail (314) and the plate rail (51).

[0090] The case rail (314) may be formed on the first upper case (31). The case rail (314) may be formed by recessing one side of the first upper cover (311). For example, the case rail (314) may be formed by recessing the lower surface of the first upper cover (311) upward. The case rail (314) may be formed by recessing in a rounded manner upward with respect to the longitudinal direction of the guide rail (314, 51). The portion of the case rail (314) facing the first extension portion (511) may be formed to be inclined with respect to the longitudinal direction of the guide rail (314, 51) so as to correspond to the inclination of the first extension portion (511). The portion of the case rail (314) facing the second extension (512) can be formed to be inclined to correspond to the inclination of the second extension (512) with respect to the longitudinal direction of the guide rail (314, 51).

[0091] The case rail (314) may have stoppers (315, 316) formed at both ends in the longitudinal direction of the guide rail (314, 51). The stoppers (315, 316) may refer to protrusions at both ends of the case rail (314) that are formed by being recessed upward. The stoppers (315, 316) may include a first stopper (315) formed at one end of the case rail (314) and a second stopper (316) formed at the other end of the case rail (314). The stoppers (315, 316) may limit the movement of the slider (43) that moves by contacting the upper surface of the case rail (314). The stoppers (315, 316) may limit the range in which the slider (43) slides in the longitudinal direction of the guide rail (314, 51).

[0092] The plate rail (51) is arranged on the lower side of the case rail (314) and can face the case rail (314) in the vertical direction. The protrusion (513) can protrude upward toward the central portion of the case rail (314) or a portion adjacent thereto.

[0093] The cap (40) can move along the plate rail (51). The slider (43) is arranged on the plate rail (51) and can move along the plate rail (51). The slider (43) can be arranged on the first extension (511) at a first position where the cap (40) closes the insertion port (54).

[0094] The distance at which the first stopper (315) and the protrusion (513) are spaced apart in the direction in which the first extension (511) extends may correspond to the length of the slider (43). In the first position, the slider (43) may be fixed in position by the case rail (314) and the plate rail (51). The upper surface of the slider (43) may contact the case rail (314), and one edge of the upper surface may contact the first stopper (315). The upper edge of the first leg (431) of the slider (43) may contact the first stopper (315). The lower surface of the slider (43) may be disposed on the first extension (511), and the other edge of the lower surface may contact the first inclined surface (514) of the protrusion (513). The lower edge of the second leg (432) of the slider (43) can contact the first inclined surface (514).

[0095] The slider (43) can be restricted from moving in the right direction or in the x direction by the first stopper (315). The slider (43) can be restricted from moving in the left direction or in the opposite direction of the x direction by the first inclined surface (514) of the protrusion (513). In other words, when no external force is applied, the slider (43) can be fixed at the first position.

[0096]

[0097] Referring to Fig. 11, the slider (43) is disposed on the plate rail (51) and can move along the plate rail (51). When an external force is applied to the cap (40) while the slider (43) is disposed on the first extension (511), the slider (43) can move. The slider (43) can move in the direction toward the protrusion (513). As the slider (43) moves, the protrusion (513) can be pressed downward by the slider (43). The protrusion (513) and the extensions (511, 512) connected to the protrusion (513) can be pressed downward. An elastic restoring force can be generated in the protrusion (513) and the extensions (511, 512) to return to their original positions. A force that moves the slider (43) to the first position can be generated by the elastic restoring force of the protrusion (513) and the extension (511, 512). In other words, even if a certain level of external force is applied to the cap (40), the cap (40) can naturally return to the first position along the longitudinal direction of the guide rail (314, 51) by the elastic restoring force.

[0098]

[0099] Referring to Fig. 12, when a force is applied to return the cap (40) to the first position by an elastic restoring force, an external force greater than the force may be applied to the cap (40). In this case, the slider (43) may move toward the second extension (512) past the protrusion (513). As the slider (43) moves, the protrusion (513) may be pressed downward by the slider (43). The protrusion (513) and the extensions (511, 512) connected to the protrusion (513) may be pressed downward. An elastic restoring force may be generated in the protrusion (513) and the extensions (511, 512) to return to their original positions. In the longitudinal direction of the slider (43), when the center of the slider (43) passes the center of the protrusion (513), a force can be generated to move the slider (43) to the second position by the elastic restoring force of the protrusion (513) and the extensions (511, 512). In other words, when the slider (43) passes the center of the protrusion (513) by an external force, the cap (40) can naturally move to the second position along the longitudinal direction of the guide rail (314, 51) by the elastic restoring force.

[0100] Accordingly, the rails (314, 51) supporting the upper and lower sides of the cap (40) are inclined in the longitudinal direction to guide the movement of the cap (40), thereby improving the usability related to the opening and closing operation of the cap (40).

[0101] The length of the protrusion (513) may be shorter than the length of the slider (43). The length of the protrusion (513) may be about 2 mm to 3 mm. If the length of the protrusion (513) is longer than the length of the slider (43), a greater external force may be required to move the slider (43) from the first position to the second position or from the second position to the first position. Alternatively, the slider (43) may not move naturally and may stop above the protrusion (513).

[0102] A support member (323) may be arranged on the lower side of the plate rail (51). The support member (323) may be formed on the second upper case (32). The support member (323) may protrude upward from the second upper cover (321) toward the protrusion member (513). The support member (323) may be spaced apart from the protrusion member (513).

[0103] The distance by which the support (323) is separated from the protrusion (513) may be greater than the maximum distance by which the protrusion (513) moves downward by the slider (43). In other words, even if the slider (43) passes while pressing the protrusion (513) downward, the support (323) does not come into contact with the protrusion (513). However, when an external force pressing the cap (40) downward occurs and the slider (43) moves abnormally downward, the support (323) comes into contact with the protrusion (513), thereby preventing the protrusion (513) from being pressed downward and preventing the protrusion (513) from being damaged.

[0104]

[0105] Referring to Fig. 13, the distance at which the second stopper (316) and the protrusion (513) are spaced apart in the direction in which the second extension (512) extends may correspond to the length of the slider (43). In the second position, the slider (43) may be fixed in position by the case rail (314) and the plate rail (51). The upper surface of the slider (43) may contact the case rail (314), and the other edge of the upper surface may contact the second stopper (316). The upper edge of the second leg (432) of the slider (43) may contact the second stopper (316). The lower surface of the slider (43) may be disposed on the second extension (512), and one edge of the lower surface may contact the second inclined surface (515) of the protrusion (513). The lower edge of the first leg (431) of the slider (43) can contact the second inclined surface (515). The slider (43) can be restricted from moving in the leftward direction or in the opposite direction of the x-direction by the second stopper (316). The slider (43) can be restricted from moving in the rightward direction or in the x-direction by the second inclined surface (515) of the protrusion (513). In other words, when no external force is applied, the slider (43) can be fixed at the second position.

[0106] Accordingly, the cap (40) is provided with a protrusion (513) and a stopper (315, 316) that fix the slider (43) of the cap (40) at each of the positions where the insertion port (54) is closed and the position where the insertion port (54) is opened, so that the position of the cap (40) can be fixed and shaking of the cap (40) can be prevented when the insertion port (54) is closed or opened.

[0107] In addition, the sliding guide structure of the cap (40) can be simplified by providing a guide rail (314, 51) which is composed of a protrusion (513) protruding on the sliding path of the cap (40) that opens and closes the insertion port (54) and an extension (511, 512) inclined thereto, and the movement of the cap (40) is guided by the elastic restoring force of the guide rail (314, 51), so that structures such as springs or magnets can be omitted, thereby reducing the volume of the device.

[0108]

[0109] FIG. 14 is a perspective view showing a rib structure of an aerosol generating device according to one embodiment of the present disclosure, and FIG. 15 is a cross-sectional view showing a rib structure of an aerosol generating device according to one embodiment of the present disclosure.

[0110] Referring to FIGS. 14 and 15, ribs (52, 53) may be formed on the plate (50). The ribs (52, 53) may protrude upward from the plate (50). The ribs (52, 53) may extend along the periphery of the plate (50).

[0111] The ribs (52, 53) may include a first rib (52) and a second rib (53). The first rib (52) may extend long in the longitudinal direction of the plate (50) or the longitudinal direction of the guide rail (314, 51) on both sides of the plate (50). The first rib (52) may be spaced apart from the guide rail (314, 51) in the width direction of the plate (50). A slit (55) may be formed between the plate rail (51) and the first rib (52). The slit (55) may extend long in the longitudinal direction of the plate (50) or the longitudinal direction of the guide rail (314, 51). The first rib (52) may be positioned higher than the plate rail (51) in the vertical direction. The first rib (52) may be, at least in part, covered by the slot (313) of the first upper cover (311) in the vertical direction.

[0112] The second rib (53) may be connected to the first rib (52). The second rib (53) may extend along the periphery of the plate (50). The second rib (53) may be positioned above the plate rail (51) in the vertical direction. At least a portion of the second rib (53) may be covered by the slot (313) of the first upper cover (311) in the vertical direction.

[0113] By providing a rib (52, 53) that is spaced apart from the guide rail (314, 51) and protrudes upward and extends in the longitudinal direction of the guide rail (314, 51), the structure for sliding the cap (40) can minimize the inflow of foreign substances into the device.

[0114]

[0115] Fig. 16 is a bottom view showing the joint structure of the upper case of an aerosol generating device according to one embodiment of the present disclosure.

[0116] Referring to FIG. 16 together with FIG. 15, the first side cover (312) may be bent from an edge or both ends of the first upper cover (311) and extended downward in the longitudinal direction of the body (10). The second side cover (322) may be bent from an edge or both ends of the second upper cover (321) and extended downward in the longitudinal direction of the body (10).

[0117] The second side cover (322) can be combined with the first side cover (312). The first side cover (312) can include a hook (318) formed by bending both ends of the first side cover (312) in the width direction (e.g., y direction) inwardly and extending in the length direction (e.g., z direction) of the first side cover (312). Both ends of the second side cover (322) in the width direction can be combined with the hook (318). The second side cover (322) can be combined with the first side cover (312) by sliding both ends of the width direction along the hook (318) in the length direction of the first side cover (312).

[0118] The second upper cover (321) may be combined with the first upper cover (311). The first upper cover (311) may have a cover groove (317) formed by a portion of the outer surface being sunken inward. The cover groove (317) may include a plurality of grooves spaced apart from each other along the perimeter of the outer surface of the first upper cover (311). The second upper cover (321) may be formed with a peripheral wall (324) extending upward along the perimeter. The cover protrusion (325) may be formed by a portion of the inner surface of the peripheral wall (324) protruding inward. The cover protrusion (325) may include a plurality of protrusions spaced apart from each other along the perimeter of the inner surface of the peripheral wall (324). The cover protrusion (325) may be arranged at a position corresponding to the cover groove (317). When the widthwise ends of the second side cover (322) are slid along the hook (318) in the lengthwise direction of the first side cover (312), the cover protrusion (325) is inserted into the cover groove (317), and the second upper cover (321) can be combined with the first upper cover (311).

[0119] Accordingly, the first upper case (31) and the second upper case (32) can be firmly joined. In addition, since the position of the plate (50) is firmly supported by the first and second upper cases (31, 32), even if the cap (40) is repeatedly moved, the position of the guide rail (314, 51) can be fixed without being distorted.

[0120]

[0121] Fig. 17 is a block diagram of an aerosol generating device (1) according to one embodiment of the present disclosure.

[0122] The aerosol generator (1) may include a power source (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 generator (1) is not limited to that illustrated in Fig. 17. That is, a person having ordinary skill in the art related to the present embodiment will understand that, depending on the design of the aerosol generator (1), some of the components illustrated in Fig. 17 may be omitted or new components may be added.

[0123] The sensor (13) can detect the status of the aerosol generator (1) or the status around the aerosol generator (1) and transmit the detected information to the control unit (12). Based on the detected information, the control unit (12) can control the aerosol generator (1) so that various functions such as controlling the operation of the cartridge heater (24) and / or heater (18), restricting smoking, determining whether a stick (S) and / or cartridge (19) is inserted, and displaying a notification are performed.

[0124] The sensor (13) may include at least one of a temperature sensor (131), a puff sensor (132), an insertion detection sensor (133), a reuse detection sensor (134), a cartridge detection sensor (135), a cap detection sensor (136), and a movement detection sensor (137).

[0125] The temperature sensor (131) can detect the temperature at which the cartridge heater (24) and / or the heater (18) is heated. The aerosol generator (1) may include a separate temperature sensor that detects the temperature of the cartridge heater (24) and / or the heater (18), or the cartridge heater (24) and / or the heater (18) itself may serve as a temperature sensor.

[0126] The temperature sensor (131) can output a signal corresponding to the temperature of the cartridge heater (24) and / or the heater (18). For example, the temperature sensor (131) can include a resistance element whose resistance value changes in response to a change in the temperature of the cartridge heater (24) and / or the heater (18). It can be implemented by a thermistor, which is an element that utilizes the property of changing resistance depending on temperature. At this time, the temperature sensor (131) can output a signal corresponding to the resistance value of the resistance element as a signal corresponding to the temperature of the cartridge heater (24) and / or the heater (18). For example, the temperature sensor (131) can be configured as a sensor that detects the resistance value of the cartridge heater (24) and / or the heater (18). At this time, the temperature sensor (131) can output a signal corresponding to the resistance value of the cartridge heater (24) and / or the heater (18) as a signal corresponding to the temperature of the cartridge heater (24) and / or the heater (18).

[0127] A temperature sensor (131) may be placed around the power source (11) to monitor the temperature of the power source (11). The temperature sensor (131) may be placed adjacent to the power source (11). For example, the temperature sensor (131) may be attached to one side of a battery, which is the power source (11). For example, the temperature sensor (131) may be mounted on one side of a printed circuit board.

[0128] A temperature sensor (131) is placed inside the body (10) and can detect the internal temperature of the body (10).

[0129] The puff sensor (132) can detect the user's puff based on various physical changes in the airflow path. The puff sensor (132) can output a signal corresponding to the puff. For example, the puff sensor (132) can be a pressure sensor. The puff sensor (132) can output a signal corresponding to the internal pressure of the aerosol generating device. Here, the internal pressure of the aerosol generating device (1) can correspond to the pressure of the airflow path through which the gas flows. The puff sensor (132) can be arranged in correspondence to the airflow path through which the gas flows in the aerosol generating device (1).

[0130] The insertion detection sensor (133) can detect insertion and / or removal of the stick (S). The insertion detection sensor (133) can detect a signal change according to the insertion and / or removal of the stick (S). The insertion detection sensor (133) can be installed around the insertion space. The insertion detection sensor (133) can detect the insertion and / or removal of the stick (S) according to a change in the permittivity inside the insertion space. For example, the insertion detection sensor (133) can be an inductive sensor and / or a capacitance sensor.

[0131] An inductive sensor may include at least one coil. The coil of the inductive sensor may be positioned adjacent to an insertion space. For example, when a magnetic field changes around a current-flowing coil, 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 of the alternating current, the current value, the voltage value, the inductance value, the impedance value, etc.

[0132] An inductive sensor can output a signal corresponding to the characteristics of the current flowing through the coil. For example, an inductive sensor can output a signal corresponding to the inductance value of the coil.

[0133] A capacitance sensor may include a conductor. The conductor of the capacitance sensor may be positioned adjacent to the insertion space. The capacitance sensor may output a signal corresponding to the electromagnetic properties of the surroundings, for example, the electrostatic capacitance around the conductor. For example, when a stick (S) including a wrapper made of a metallic material is inserted into the insertion space, the electromagnetic properties around the conductor may be changed by the wrapper of the stick (S).

[0134] A reuse detection sensor (134) can detect whether the stick (S) has been reused. The reuse detection sensor (134) may be a color sensor. The color sensor can detect the color of the stick (S). The color sensor can detect the color of a portion of a wrapper that wraps the outside of the stick (S). The color sensor can detect a value for an optical characteristic corresponding to the color of an object based on light reflected from the object. For example, the optical characteristic may be a wavelength of light. The color sensor may be implemented as a single component with the proximity sensor, or may be implemented as a separate component distinct from the proximity sensor.

[0135] At least some of the wrappers constituting the stick (S) may change color due to the aerosol. The reuse detection sensor (134) may be positioned corresponding to a position where at least some of the wrappers whose color changes due to the aerosol are disposed when the stick (S) is inserted into the insertion space. For example, before the stick (S) is used by a user, the color of at least some of the wrappers may be a first color. At this time, as at least some of the wrappers are wetted by the aerosol generated by the aerosol generating device (1) while passing through the stick (S), the color of at least some of the wrappers may change to a second color. Meanwhile, the color of at least some of the wrappers may be maintained at the second color after changing from the first color to the second color.

[0136] The cartridge detection sensor (135) can detect the mounting and / or removal of the cartridge (19). The cartridge detection sensor (135) can be implemented by an inductance-based sensor, a capacitive sensor, a resistance sensor, a Hall sensor (hall IC) using the Hall effect, etc.

[0137] The cap detection sensor (136) can detect the attachment and / or removal of the cap. When the cap is separated from the body (10), the cartridge (19) and a portion of the body (10) covered by the cap 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, or the like.

[0138] A motion detection sensor (137) can detect the movement of the aerosol generating device. The motion detection sensor (137) can be implemented with at least one of an acceleration sensor and a gyro sensor.

[0139] In addition to the sensors (131 to 137) described above, the sensor (13) may further include at least one of a humidity sensor, a pressure sensor, a magnetic sensor, a position sensor (GPS), and a proximity sensor. Since the functions of each sensor can be intuitively inferred by a person skilled in the art from its name, a detailed description thereof may be omitted.

[0140] The output unit (14) can output information on the status of the aerosol generator (1) and provide it to the user. The output unit (14) may include at least one of a display (141), a haptic unit (142), and an audio output unit (143), but is not limited thereto. When the display (141) and the touch pad form a layered structure to form a touch screen, the display unit (141) can be used as an input device in addition to an output device.

[0141] The display (141) can visually provide information about the aerosol generator (1) to the user. For example, the information about the aerosol generator (1) can mean various information such as the charging / discharging status of the power supply (11) of the aerosol generator (1), the preheating status of the heater (18), the insertion / removal status of the stick (S) and / or cartridge (19), the mounting / removal status of the cap, or the status in which the use of the aerosol generator (1) is restricted (e.g., detection of an abnormal item), and the display (141) can output the above information to the outside. For example, the display (141) can be in the form of an LED light-emitting element. For example, the display (141) can be a liquid crystal display panel (LCD), an organic light-emitting display panel (OLED), etc.

[0142] The haptic unit (142) can provide tactile information about the aerosol generator (1) to the user by converting an electrical signal into a mechanical stimulus or an electrical stimulus. For example, the haptic unit (142) can generate a vibration corresponding to the completion of the initial preheating when the initial power is supplied to the cartridge heater (24) and / or heater (18) for a set period of time. The haptic unit (142) can include a vibration motor, a piezoelectric element, or an electrical stimulation device.

[0143] The acoustic output unit (143) can provide information about the aerosol generator (1) to the user audibly. For example, the acoustic output unit (143) can convert an electrical signal into an acoustic signal and output it to the outside.

[0144] The power source (11) can supply power used to operate the aerosol generator (1). The power source (11) can supply power so that the cartridge heater (24) and / or the heater (18) can be heated. In addition, the power source (11) can supply power required for the operation of other components provided in the aerosol generator (1), such as a sensor (13), an output unit (14), an input unit (15), a communication unit (16), and a memory (17). The power source (11) can be a rechargeable battery or a disposable battery. For example, the power source (11) can be a lithium polymer (LiPoly) battery, but is not limited thereto.

[0145] Although not shown in FIG. 17, the aerosol generator (1) may further include a power protection circuit. The power protection circuit may be electrically connected to the power source (11) and include a switching element.

[0146] The power protection circuit can block the power supply (11) according to certain conditions. For example, the power protection circuit can block the power supply (11) when the voltage level of the power supply (11) is higher than a first voltage corresponding to overcharge. For example, the power protection circuit can block the power supply (11) when the voltage level of the power supply (11) is lower than a second voltage corresponding to overdischarge.

[0147] The heater (18) can receive power from the power source (11) and heat the medium or aerosol generating material within the stick (S). Although not illustrated in FIG. 10, the aerosol generating device (1) may further include a power conversion circuit (e.g., a DC / DC converter) that converts the power of the power source (11) and supplies it to the cartridge heater (24) and / or the heater (18). In addition, when the aerosol generating device (1) generates the aerosol by induction heating, the aerosol generating device (1) may further include a DC / AC converter that converts the direct current power of the power source (11) into alternating current power.

[0148] The control unit (12), sensor (13), output unit (14), input unit (15), communication unit (16), and memory (17) can receive power from the power source (11) and perform their functions. Although not illustrated in FIG. 17, the device may further include a power conversion circuit, for example, an LDO (low dropout) circuit or a voltage regulator circuit, which converts the power of the power source (11) and supplies it to each component. In addition, although not illustrated in FIG. 17, a noise filter may be provided between the power source (11) and the heater (18). The noise filter may be a low pass filter. The low pass filter may include at least one inductor and a capacitor. The cutoff frequency of the low pass filter may correspond to the frequency of the high frequency switching current applied from the power source (11) to the heater (18).

[0159] The control unit (12) can control the overall operation of the aerosol generator (1). In one embodiment, the control unit (12) may include at least one processor. The processor may be implemented as an array of multiple logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory storing a program executable by the microprocessor. Furthermore, it will be understood by those skilled in the art to which the present embodiment pertains that the processor may be implemented as other types of hardware.

[0160] The control unit (12) can control the temperature of the heater (18) by controlling the supply of power from the power source (11) to the heater (18). The control unit (12) can control the temperature of the cartridge heater (24) and / or the heater (18) based on the temperature of the cartridge heater (24) and / or the heater (18) 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 of the cartridge heater (24) and / or the heater (18). For example, the control unit (12) can determine a target temperature for the cartridge heater (24) and / or the heater (18) based on a temperature profile stored in the memory (17).

[0161] The aerosol generator (1) may include a power supply circuit (not shown) electrically connected to the power supply (11) between the power supply (11) and the cartridge heater (24) and / or the heater (18). The power supply circuit may be electrically connected to the cartridge heater (24), the heater (18), or the induction coil (181). The power supply circuit may include at least one switching element. The switching element may be implemented by a bipolar junction transistor (BJT), a field effect transistor (FET), or the like. The control unit (12) may control the power supply circuit.

[0162] The control unit (12) can control power supply by controlling the switching of the switching elements of the power supply circuit. The power supply circuit may be an inverter that converts direct current power output from the power source (11) into alternating current power. For example, the inverter may be configured as a full-bridge circuit or a half-bridge circuit including a plurality of switching elements.

[0163] The control unit (12) can turn on the switching element so that power is supplied from the power source (11) to the cartridge heater (24) and / or the heater (18).

[0164] The control unit (12) can control the voltage output from the power source (11) by controlling the switching of the switching element of the power supply circuit. The power conversion circuit can convert the voltage output from the power source (11). For example, the power conversion circuit can include a buck converter that steps down the voltage output from the power source (11). For example, the power conversion circuit can be implemented using a buck-boost converter, a zener diode, etc.

[0165] The control unit (12) can control the on / off operation of the switching element included in the power conversion circuit to adjust the level of the voltage output from the power conversion circuit. When the on state of the switching element continues, the level of the voltage output from the power conversion circuit may correspond to the level of the voltage output from the power source (11). The duty ratio for the on / off operation of the switching element may correspond to the ratio of the voltage output from the power conversion circuit to the voltage output from the power source (11). As the duty ratio for the on / off operation of the switching element decreases, the level of the voltage output from the power conversion circuit may decrease. The heater (18) can be heated based on the voltage output from the power conversion circuit.

[0166] The control unit (12) can control power to be supplied to the heater (18) using at least one of the pulse width modulation (PWM) method and the proportional-integral-differential (PID) method.

[0167] For example, the control unit (12) can control a current pulse having a predetermined frequency and duty ratio to be supplied to the heater (18) using the PWM method. The control unit (12) can control the power supplied to the heater (18) by adjusting the frequency and duty ratio of the current pulse.

[0168] For example, the control unit (12) can determine a target temperature that is the target of control based on a temperature profile. The control unit (12) can control the power supplied to the heater (18) by using the PID method, which is a feedback control method using a difference value between the temperature of the heater (18) and the target temperature, a value obtained by integrating the difference value over time, and a value obtained by differentiating the difference value over time.

[0169] The control unit (12) can prevent the cartridge heater (24) and / or the heater (18) from overheating. For example, the control unit (12) can control the operation of the power conversion circuit so that the supply of power to the cartridge heater (24) and / or the heater (18) is cut off based on the temperature of the cartridge heater (24) and / or the heater (18) exceeding a preset limit temperature. For example, the control unit (12) can reduce the amount of power supplied to the cartridge heater (24) and / or the heater (18) by a certain percentage based on the temperature of the cartridge heater (24) and / or the heater (18) exceeding a preset limit temperature. For example, the control unit (12) can determine that the aerosol generating substance contained in the cartridge (19) is exhausted based on the temperature of the cartridge heater (24) exceeding the limit temperature, and can cut off the supply of power to the cartridge heater (24).

If the temperature of the power source (11) is lower than the first limit temperature, the control unit (12) can control the power source (11) to be charged based on a preset charging current. If the temperature of the power source (11) is higher than or equal to the first limit temperature, the control unit (12) can block charging of the power source (11).

For example, the control unit (12) can determine that the stick (S) is removed from the insertion space when the temperature of the heater (18) is higher than a limited temperature or when the temperature change slope of the heater (18) is higher than a set slope. When it is determined that the stick (S) is removed from the insertion space, the control unit (12) can cut off the power supply to the cartridge heater (24) and / or the heater (18).

[0176] The control unit (12) can control the power supply time and / or power supply amount to the heater (18) according to the state of the stick (S) detected by the sensor (13). The control unit (12) can check the level range that includes the level of the signal of the capacitance sensor based on a lookup table. The control unit (12) can determine the moisture content of the stick (S) according to the checked level range.

[0178] The control unit (12) can determine whether the stick (S) inserted into the insertion space has been reused through the reuse detection sensor (134). For example, the control unit (12) can compare the sensing value of the signal of the reuse detection sensor with a first reference range that includes a first color, and if the sensing value is included in the first reference range, it can determine that the stick (S) has not been used. For example, the control unit (12) can compare the sensing value of the signal of the reuse detection sensor with a second reference range that includes a second color, and if the sensing value is included in the second reference range, it can determine that the stick (S) has been used. If it is determined that the stick (S) has been used, the control unit (12) can cut off the supply of power to the cartridge heater (24) and / or the heater (18).

[0180] The control unit (12) can determine whether the aerosol generating material of the cartridge (19) is exhausted. For example, the control unit (12) can preheat the cartridge heater (24) and / or the heater (18) by applying power, and determine whether the temperature of the cartridge heater (24) exceeds a limited temperature during the preheating period. If the temperature of the cartridge heater (24) exceeds the limited temperature, the control unit (12) can determine that the aerosol generating material of the cartridge (19) is exhausted. If the control unit (12) determines that the aerosol generating material of the cartridge (19) is exhausted, the control unit (12) can cut off the supply of power to the cartridge heater (24) and / or the heater (18).

[0181] The control unit (12) can determine whether the cartridge (19) is usable. For example, the control unit (12) can determine that the cartridge (19) is unusable if the current number of puffs is greater than or equal to the maximum number of puffs set for the cartridge (19) based on data stored in the memory (17). For example, the control unit (12) can determine that the cartridge (19) is unusable if the total time that the heater (24) has been heated is greater than or equal to the preset maximum time or the total amount of power supplied to the heater (24) is greater than or equal to the preset maximum amount of power.
