Description

Aerosol generator

[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 a conventional aerosol generating device, an object such as a stick may be inserted into the device without a cartridge installed. In this case, the aerosol generating device cannot normally generate aerosol. However, a conventional aerosol generating device has a problem in that it cannot determine whether a cartridge is installed when an object such as a stick is inserted into the device, and it cannot provide an alarm to the user regarding a cartridge not being installed. In addition, when a cartridge is not installed, power is supplied to a terminal for supplying power to the cartridge or to a heater for heating the stick, which may cause the device to operate unstable and malfunction.

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

[0005] Another object may be to provide an aerosol generating device that determines whether a cartridge is engaged with a body based on the body receiving or approaching an object.

[0006] Another object may be to provide an aerosol generating device that outputs a relevant alarm based on whether a cartridge is engaged with a body, while the body is receiving or in proximity to an object.

[0007] Another object may be to provide an aerosol generating device that controls whether power is supplied to the heater based on whether a cartridge is coupled to the body, while the body is receiving or in proximity to an object.

[0008] Another object may be to provide an aerosol generating device that determines whether a cartridge is engaged via a cartridge power supply terminal based on an object being received or brought into proximity to the body.

[0009] According to one aspect of the present disclosure for achieving the above-described object, there is provided an aerosol generating device comprising: a body; a cartridge coupled to the body and including a heater for heating an aerosol generating substance; a sensor disposed on the body; and a control unit, wherein the control unit determines whether an object is received or approached by the body based on a signal output from the sensor, and determines whether the cartridge is coupled to the body based on the object being received or approached.

[0010] According to at least one embodiment of the present disclosure, user convenience can be improved by determining whether a cartridge is engaged with a body based on an object being received or brought into proximity to the body, and outputting a related alarm.

[0011] According to at least one embodiment of the present disclosure, by determining whether a cartridge is engaged with a body based on whether an object is received or brought into proximity to the body and controlling whether power is supplied to the heater, unnecessary power supply to the cartridge or to the heater can be prevented, and operation of the device can be prevented from becoming unstable or malfunctioning.

[0012] According to at least one embodiment of the present disclosure, when an object is received or approached by the body, it is possible to prevent unnecessary power waste for checking whether the cartridge is coupled by determining whether the cartridge is coupled through the cartridge power supply terminal.

[0013] Further scope of the applicability of the present disclosure will become apparent from the detailed description below. However, since various modifications and variations within the spirit and scope of the present disclosure will be apparent to those skilled in the art, it should be understood that the detailed description and specific examples, such as preferred embodiments of the present disclosure, are given by way of example only.

[0022] Hereinafter, embodiments disclosed in this specification will be described in detail with reference to the attached drawings. Regardless of the drawing numbers, identical or similar components are assigned the same reference numerals, and redundant descriptions thereof will be omitted.

[0023] The suffixes "module" and "part" used for components in the following description may be assigned or used interchangeably solely for the convenience of writing the specification. "Module" and "part" do not, by themselves, have distinct meanings or roles.

[0024] In addition, when describing the embodiments disclosed in this specification, if it is determined that a detailed description of related known technology may obscure the gist of the embodiments disclosed in this specification, the detailed description thereof will be omitted. In addition, the attached drawings are only intended to facilitate understanding of the embodiments disclosed in this specification, and the technical concepts disclosed in this specification are not limited by the attached drawings. It should be understood that the attached drawings include all modifications, equivalents, and substitutes included within the spirit and technical scope of the present disclosure.

[0025] Terms that include ordinal numbers, such as first, second, etc., may be used to describe various components. However, these components are not limited by these terms. These terms are used solely to distinguish one component from another.

[0026] When a component is referred to as being "connected" or "connected" to another component, it should be understood that it may be directly connected or connected to that other component, although it should be understood that there may be other components intervening. Conversely, when a component is referred to as being "directly connected" or "connected" to another component, it should be understood that there are no other components intervening.

[0027] Singular expressions include plural expressions unless the context clearly indicates otherwise.

[0028] Throughout this specification, the direction of the aerosol generator (1) may be defined based on an orthogonal coordinate system. In the orthogonal coordinate system, the x-axis direction may be defined as the left-right direction of the aerosol generator (1). The y-axis direction may be defined as the front-back direction of the aerosol generator (1). The z-axis direction may be defined as the up-down direction of the aerosol generator (1).

[0029] Throughout this specification, "upstream" and "downstream" may be determined based on the direction of airflow that causes the generated aerosol to be drawn into the user's mouth or lungs when the user inhales. For example, in FIGS. 1 to 3 , the generated aerosol flows from the portion of the stick (S) that is inserted into the aerosol generating device to the portion that is not inserted, so the portion of the stick (S) that is inserted into the aerosol generating device is located upstream of the portion that is not inserted. "Upstream" and "downstream" may be determined relative to each other between components.

[0031] Figures 1 to 3 illustrate an aerosol generating device (1) according to one embodiment of the present disclosure.

[0032] Referring to FIG. 1, the aerosol generator (1) may include at least one of a power source (11), a control unit (12), a sensor (13), and a cartridge (19). At least one of the power source (11), the control unit (12), and the sensor (13) may be placed inside a body (10) of the aerosol generator (1). The body (10) may provide a space into which a cartridge (19) may be inserted.

[0033] The cartridge (19) may contain an aerosol-generating substance in any one of a liquid, solid, gaseous, or gel state. The aerosol-generating substance may include a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing substance including a volatile tobacco flavoring component, or may be a liquid containing a non-tobacco substance.

[0034] The cartridge (19) can be detachably coupled to one side of the body (10). The cartridge (19) can provide an insertion space (43) that is opened upward so that a stick (S), which is an aerosol generating material, can be inserted. The insertion space (43) can be formed by being sunken into the interior of the cartridge (19) to a predetermined depth so that at least a portion of the stick (S) can be inserted. The depth of the insertion space (43) can correspond to the length of the area in the stick (S) that contains the aerosol generating material and / or medium. The lower end of the stick (S) can be inserted into the interior of the cartridge (19), and the upper end of the stick (S) can protrude to the outside of the cartridge (19). The user can hold the upper end of the stick (S), which is exposed to the outside, in his / her mouth and inhale air.

[0035] The cartridge (19) can be mounted on the body (10) by being inserted into a space formed on one side of the body (10) at least in part. The airflow channel (CN) can be defined by a part of the cartridge and / or a part of the body (10), and the airflow channel (CN) can be communicated with the insertion space.

[0036] The body (10) can be formed in a structure in which outside air can flow into the interior of the body (10) while the cartridge (19) is inserted. At this time, the outside air flowing into the body (10) can pass through the cartridge (19) and flow into the user's oral cavity.

[0037] The cartridge (19) may include a storage portion (C0) containing an aerosol generating material and a heater (24) for heating the aerosol generating material in the storage portion (C0). The heater (24) may be referred to as a cartridge heater. A liquid delivery means for impregnating (containing) the aerosol generating material may be disposed inside the storage portion (C0).

The heater (24) may be electrically connected to a power source (11). The heater (24) can be directly heated by receiving current from the power source (11).

[0038] The cartridge (19) can generate an aerosol. As the liquid delivery means is heated by the heater (24), the aerosol can be generated. Tobacco material can be added to the aerosol while the aerosol generated by the heater (24) passes through the stick (S), and the aerosol added with the tobacco material can be inhaled into the user's mouth through one end of the stick (S).

[0039] The heater (24) can be placed adjacent to the lower end of the insertion space (43). By placing the heater (24) adjacent to one end of the stick (S) accommodated in the insertion space (43), the heat transfer efficiency of the aerosol can be increased.

The control unit (12) can control the operation of a display, a motor, etc. installed in the aerosol generator (1). The control unit (12) can check the status of each component of the aerosol generator (1) to determine whether the aerosol generator (1) is in an operable state.

[0043] The control unit (12) can analyze the results detected by the sensor (13) and control the processes to be performed thereafter. For example, the control unit (12) can control the power supplied to the heater (24) so ​​that the operation of the heater (24) is started or ended based on the results detected by the sensor (13). For example, the control unit (12) can control the amount of power supplied to the heater (24) and the time for which the power is supplied so that the heater (24) can be heated to a predetermined temperature or maintained at an appropriate temperature based on the results detected by the sensor (13).

[0044] The sensor (13) may include at least one of a temperature sensor, a puff sensor, an insertion detection sensor, a color sensor, a cartridge detection sensor, a cap detection sensor, and a proximity sensor. For example, the sensor (13) may sense at least one of the temperature of the heater (24), the temperature of the power source (11), and the temperature inside and outside the body (10). For example, the sensor (13) may sense the user's puff. For example, the sensor (13) may sense whether the stick (S) is inserted into the insertion space.

The heater (18) may be electrically connected to a power source (11). The heater (18) may be directly heated by receiving current from the power source (11).

[0049] For example, the aerosol generator (1) may include an induction coil surrounding a heater (18). The induction coil may heat the heater (18). The heater (18) may be a susceptor, and the heater (18) may be heated by a magnetic field generated by an AC current flowing through the induction coil. The magnetic field may penetrate the heater (18) and generate an eddy current within the heater (18). The current may generate heat in the heater (18).

[0050] Meanwhile, a susceptor may be included inside the stick (S), and the susceptor inside the stick (S) may be heated by a magnetic field generated by an AC current flowing through the induction coil.

[0051] The cartridge (19) may be formed integrally with the body (10) or may be detachably coupled to the body (10).

[0052] For example, referring to FIG. 2, the cartridge (19) is formed integrally with the body (10) and can communicate with the insertion space through an airflow channel (CN).

[0053] For example, referring to FIG. 3, a space is formed on one side of the body (10), and at least a portion of the cartridge (19) is inserted into the space formed on one side of the body (10) so that the cartridge (19) can be mounted on the body (10). The airflow channel (CN) can be defined by a portion of the cartridge and / or a portion of the body (10), and the cartridge (19) can communicate with the insertion space through the airflow channel (CN).

[0054] The cartridge (19) can generate an aerosol. The aerosol can be generated as the liquid delivery means is heated by the cartridge heater (24). The aerosol can be generated by heating the stick (S) by the heater (18). Tobacco material can be added to the aerosol while the aerosol generated by the cartridge heater (24) and the heater (18) passes through the stick (S), and the aerosol added with the tobacco material can be inhaled into the user's mouth through one end of the stick (S).

[0055] The control unit (12) can analyze the results detected by the sensor (13) and control the processes to be performed thereafter. For example, the control unit (12) can control the power supplied to the cartridge heater (18, 24) so ​​that the operation of the heater (18, 24) is started or ended based on the results detected by the sensor (13). For example, the control unit (12) can control the amount of power supplied to the heater (18, 24) and the time for which the power is supplied so that the heater (18, 24) can be heated to a predetermined temperature or maintained at an appropriate temperature based on the results detected by the sensor (13).

[0080] FIG. 6 is a flowchart showing a determination of whether a cartridge is coupled and device control of an aerosol generating device according to one embodiment of the present disclosure, and FIGS. 7 and 8 are cross-sectional views showing a stick received in a state where a cartridge is coupled or uncoupled in an aerosol generating device according to one embodiment of the present disclosure.

[0081] Referring to FIG. 7 and FIG. 8 together with FIG. 6, the control unit (12) can determine whether an object is received in or close to the body (A10) (S610).

[0082] The sensor (138, see FIGS. 7 to 11) may be disposed on one side of the body (A10). The sensor (138) may be disposed on the upper portion of the column (A440) of the upper body (420). The sensor (138) may face the outside of the column (A440). The sensor (138) may face the direction in which the column (A440) faces the cartridge (A19). When the cartridge (A19) is coupled to the body (A10), the sensor (138) may face the cartridge (A19). The sensor (138) may be disposed adjacent to the insertion port (A304) of the cap (A30). When the cap (A30) is coupled to the body (A10), the sensor (138) may be positioned adjacent to the insertion port (A304) of the cap (A30).

[0083] The sensor (138) can emit light in a direction intersecting the longitudinal direction of the column (A440). The sensor (138) can output a signal based on the intensity of light received from the outside. The sensor (138) can detect an object approaching. For example, the sensor (138) can detect light reflected from the stick (S). The sensor (138) can detect that the stick (S) is received or inserted into the body (A10). For example, the sensor (138) can detect light reflected from the cartridge (A19). The sensor (180) can detect that the cartridge (A19) is received or mounted in the body (A10).

[0084] The sensor (138) may be a proximity sensor. The sensor (138) may be an optical proximity sensor. For example, the sensor (138) may be an infrared sensor. The infrared sensor may include a sensing light-emitting unit that emits infrared light toward the outside. The infrared sensor may include a sensing light-receiving unit that receives infrared light. Infrared light emitted from the sensing light-emitting unit may be reflected from an object and enter the sensing light-receiving unit. The sensing light-receiving unit may obtain information about the entered infrared light.

[0085] Meanwhile, the sensor (138) may include at least one of a magnetic proximity sensor, an ultrasonic proximity sensor, and an inductive proximity sensor.

[0086] The control unit (12) can receive a signal output by the sensor (138). Based on the signal output by the sensor (138), the control unit (12) can determine whether an object is received or approached the body (A10). According to the present embodiment, the control unit (12) can determine whether a stick (S) is received or inserted through the sensor (138). However, depending on the range of the signal output by the sensor (138), the control unit (12) can also determine that a cartridge (A19) is received or mounted in addition to the stick (S).

[0087] For example, the control unit (12) may determine that the first object is received or is in proximity to the body (A10) when the signal output from the sensor (138) has a value within the first range. The control unit (12) may determine that the first object is not received or is not in proximity to the body (A10) when the signal output from the sensor (138) has a value outside the first range. Here, the first object may be a stick (S).

[0088] For example, the control unit (12) may determine that a second object is accommodated in or near the body (A10) when the signal output from the sensor (138) has a value within the second range. The control unit (12) may determine that a second object is not accommodated in or near the body (A10) when the signal output from the sensor (138) has a value outside the second range. Here, the second object may be a cartridge (A19).

[0089] If it is determined that an object is accommodated or is close to the body (A10) ('Yes' in S620), the control unit (12) can determine whether to couple the cartridge (A19) to the body (A10) (S630).

[0090] The cap (A30) can be coupled to the body (A10). The cap (A30) can cover or surround the upper body (A420). When the cartridge (A19) is mounted on the body (A10), the cap (A30) can cover or surround the upper body (A420) and the cartridge (A19).

[0091] The cap (A30) may include a cover (A310). The cover (310) may open and close the insertion port (A304). When the cap (A30) is coupled to the body (A10), the insertion port (A304) is aligned with the opening of the insertion space (A214).

[0092] The stick (S) can be accommodated or inserted into the body (A10). When the stick (S) pushes the cover (310), the cover (310) can pivot toward the inside of the cap (A30) to open the insertion port (A304). When the cartridge (A19) is not coupled to the body (A10) (see FIG. 7), the stick (S) can be accommodated or inserted into the body (A10) by pushing the cover (310) of the cap (A30) and penetrating the insertion port (A304). The inserted stick (S) can be supported by the cover (310) and the upper body (A440). In a state where the cartridge (A19) is coupled to the body (A10) (see FIG. 8), the stick (S) can be inserted into the insertion space (A214) of the cartridge (A19) by pushing out the cover (310) of the cap (A30) and penetrating the insertion port (A304). The inserted stick (S) can be supported by the cover (310) and the inner wall (A212) of the first container (A210).

[0093] The control unit (12) can determine whether the stick (S) is received in the insertion port (A304) and / or the body (A10) based on the signal output from the sensor (138). The control unit (12) can determine whether the cartridge (19) is engaged based on the stick (S) being received in the insertion port (A304) and / or the body (A10).

[0094] The control unit (12) can determine whether the cartridge (A19) is connected to the body (A10) via the power supply terminal (A428).

[0095] The power supply terminal (A428) may be disposed on the body (A10). The power supply terminal (A428) may be disposed on the bottom surface of the mount (A430). The power supply terminal (A428) may be electrically connected to the power source (11). When the cartridge (A19) is coupled to the body (A10), the power supply terminal (A428) may be in contact with the connection terminal (A231) provided on the cartridge (A19). The power supply terminal (A428) may be electrically connected to a heater (A242) (e.g., heater (24)) through the connection terminal (A231). The heater (A242) may wind a wick (A241) (e.g., liquid delivery means) or may be in contact with one side of the wick (A241). The wick (A241) can be impregnated with an aerosol production material from the storage unit (C0). The heater (A242) heats the wick (A241) so that an aerosol can be generated. The power supply terminal (A428) can be referred to as a cartridge terminal.

[0096] The control unit (12) can control the power supply (11) so that a predetermined current is applied through the power supply terminal (A428) based on whether the stick (S) is received or is in proximity. The control unit (12) can determine whether the cartridge (A19) is engaged based on whether a current corresponding to the predetermined current is received through the power supply terminal (A428). For example, the control unit (12) can control the power supply (11) to transmit a pulse current through one of the power supply terminals (A428). The control unit (12) can determine whether the cartridge (A19) is engaged based on whether a pulse current is received through another of the power supply terminals (A428).

[0097] The control unit (12) can control the power supply (11) to cut off the current supply to the power supply terminal (A428) based on whether the stick (S) is not received or is not in proximity. That is, the control unit (12) determines whether the stick (S) is received or in proximity through the sensor (138), and can determine whether the cartridge (A19) is engaged through the power supply terminal (A428) only when it determines that the stick (S) is received or in proximity to the body (A10).

[0098] Accordingly, unnecessary power waste can be prevented to check whether the cartridge is combined.

[0099] Meanwhile, if it is determined that the object is not accommodated or is not close to the body (A10) ('No' in S620), the control unit (12) can repeatedly receive the signal output by the sensor (138).

[0100] If it is determined that the cartridge (A19) is not coupled to the body (A10) ('No' in S640), the control unit (12) can control the power supply (11) to cut off the power supply to the heater (A242) (S670).

[0101] Referring to Fig. 7, there may be a case where the cap (A30) is coupled to the body (A10) while the cartridge (A19) is not coupled to the body (A10). While the cartridge (A19) is not coupled to the body (A10), the stick (S) may be received or inserted into the body (A10) by the user. The stick (S) may be received or inserted into the body (A10) by pushing out the cover (310) of the cap (A30) and penetrating through the insertion port (A304).

[0102] That is, the control unit (12) can control the power supply (11) to cut off the power supply to the heater (A242) when the cartridge (A19) is not coupled to the body (A10), even if the stick (S) is accommodated in the body (A10).

[0103] Accordingly, it is possible to prevent unnecessary power supply to the cartridge (A19) or the heater (A242), and to prevent the operation of the aerosol generator (1) from becoming unstable or malfunctioning.

[0104] If it is determined that the cartridge (A19) is not coupled to the body (A10) ('No' in S640), the control unit (12) can output a first alarm through the output unit (14) (S680). The first alarm may include information related to the non-coupling of the cartridge (A19). For example, the first alarm may include at least one of information indicating that the stick (S) is received in the body (A10) and the cartridge (A19) is not coupled, information inducing coupling of the cartridge (A19), and information indicating the heating cutoff of the heater (24).

[0105] Accordingly, user convenience can be improved.

[0106] If it is determined that the cartridge (A19) is coupled to the body (A10) ('Yes' in S640), the control unit (12) can control the power supply (11) to supply power to the heater (24) (S650).

[0107] Referring to Fig. 8, when the cartridge (A19) and the cap (A30) are combined with the body (A10), the stick (S) can be received or inserted into the body (A10) by the user. The stick (S) can be inserted into the insertion space (A214) of the cartridge (A19) by pushing out the cover (310) of the cap (A30) and penetrating the insertion port (A304).

[0108] That is, the control unit (12) can control the power source (11) to supply power to the heater (24) based on the stick (S) being accommodated in the body (A10) and the cartridge (A19) being coupled to the body (A10).

[0109] Accordingly, in a state where the stick (S) is accommodated in the body (A10) and the cartridge (A19) is determined to be coupled to the body (A10), power can be supplied to the heater (A242) to normally generate an aerosol.

[0110] Meanwhile, the body (A10) may further be equipped with a cap detection sensor (136, see FIG. 12). The cap detection sensor (136) can detect the attachment and / or removal of the cap (A30). The cap detection sensor (136) may be implemented by a contact sensor, a Hall sensor (hall IC), an optical sensor, or the like.

[0111] The control unit (12) can determine whether the cap (A30) is coupled to the body (A10) based on a signal output from the cap detection sensor (136). The control unit (12) can determine whether the cap (A30) is coupled based on the stick (S) being accommodated in the body (A10) and the cartridge (A19) being coupled to the body (A10).

[0112] The control unit (12) can control the power supply (11) to supply power to the heater (24) based on the stick (S) being accommodated in the body (A10) and the cartridge (A19) and the cap (A30) being coupled to the body (A10). If the control unit (12) determines that the cap (A30) is not coupled to the body (A10) even though the stick (S) is accommodated in the body (A10) and the cartridge (A19) is coupled to the body (A10), the control unit (12) can control the power supply (11) to cut off the power supply to the heater (A242).

[0113] If it is determined that the cartridge (A19) is coupled to the body (A10) ('Yes' in S640), the control unit (12) may output a second alarm (S660) via the output unit (14, see FIG. 12). The second alarm may include information related to the insertion of the stick. For example, the second alarm may include at least one of information indicating that the stick (S) has been received in the body (A10) and information indicating the start of heating of the heater (24).

[0114] Accordingly, user convenience can be improved.

[0115]

[0116] Figures 9 and 10 are cross-sectional views illustrating a stick accommodated in an aerosol generating device according to another embodiment of the present disclosure, with the cartridge either engaged or disengaged. Any features that overlap with the descriptions provided with reference to Figures 6 to 8 will be omitted for brevity.

[0117] Referring to FIGS. 9 and 10 together with FIG. 6, an insertion space (B134) may be provided in the body (B10). The insertion space (B134) may be located inside the upper body (B120). The cartridge coupling space (B124a) may be formed on one side of the upper body (B120). The cartridge coupling space (B124a) may be defined by the mounting portion (B122), the partition wall (B125), and the extension portion (B140) of the upper body (B120).

[0118] The sensor (138) may be arranged on one side of the body (B10). The sensor (138) may be arranged on the upper part of the upper body (B120). The sensor (138) may face the cartridge coupling space (B124a). When the cartridge (B19) is coupled to the body (B10), the sensor (138) may face the cartridge (B19). The sensor (138) may be arranged adjacent to the insertion space (B134). The sensor (138) may be arranged adjacent to the insertion opening (B214) of the cap (B200, see FIG. 5). When the cap (B200) is coupled to the body (B10), the sensor (138) may be positioned adjacent to the insertion opening (B214) of the cap (B200).

[0119] The sensor (138) may be disposed spaced apart from the second heater (B18) (e.g., heater (18)). The heater (B18) may be disposed around the insertion space (B134). The second heater (B18) may be disposed to surround at least a portion of the insertion space (B134). The second heater (B18) may heat the insertion space (B134) or the stick (S) inserted into the insertion space (B134). In the longitudinal direction of the insertion space (B134), the sensor (138) may be disposed above the second heater (B18). The second heater may be referred to as a stick heater or a cigarette heater.

[0120] The control unit (12) can receive a signal output by the sensor (138). Based on the signal output by the sensor (138), the control unit (12) can determine whether an object is received or approached by the body (B10). Based on the signal output by the sensor (138), the control unit (12) can determine whether a stick (S) is received or inserted into the insertion space (B134).

[0121] The control unit (12) can determine whether to couple the cartridge (B19) to the body (B10) based on whether an object is received or inserted into the insertion space (B134).

[0122] The control unit (12) can determine whether the cartridge (B19) is coupled to the body (B10) via the power supply terminal (B128). The power supply terminal (B128) can be arranged on the upper surface of the lower body (B110). The power supply terminal (B128) can be electrically connected to the power source (11). When the cartridge (B19) is coupled to the body (B10), the power supply terminal (B128) can come into contact with the connection terminal (B331) provided in the cartridge (B19). The power supply terminal (B128) can be electrically connected to a heater (B342) (e.g., heater (24)) via the connection terminal (B331). The heater (B342) can wind a wick (B341) (e.g., liquid delivery means) or can be in contact with one side of the wick (B341). The wick (B341) can be impregnated with an aerosol production material of the storage unit (C0). The heater (B342) heats the wick (B341) so that an aerosol can be generated.

[0123] The control unit (12) can control the power supply (11) so that a predetermined current is applied through the power supply terminal (B128) based on whether the stick (S) is received or is in proximity. The control unit (12) can determine whether the cartridge (B19) is engaged based on whether a current corresponding to the predetermined current is received through the power supply terminal (B128). For example, the control unit (12) can control the power supply (11) to transmit a pulse current through one of the power supply terminals (B128). The control unit (12) can determine whether the cartridge (B19) is engaged based on whether a pulse current is received through another of the power supply terminals (B128).

[0124] If it is determined that the cartridge (B19) is not coupled to the body (B10), the control unit (12) can control the power supply (11) to cut off the power supply to the heater (B342).

[0125] Referring to Fig. 9, regardless of whether the cartridge (B19) is coupled to the body (B10), the stick (S) can be accommodated or inserted into the insertion space (B134). That is, the control unit (12) can control the power supply (11) to cut off the power supply to the heater (B342) if the cartridge (B19) is not coupled to the body (B10), even if the stick (S) is accommodated in the body (B10).

[0126] If it is determined that the cartridge (B19) is not coupled to the body (B10), the control unit (12) can control the power supply (11) to cut off the power supply to the second heater (B18). That is, even if the stick (S) is accommodated in the body (B10), the control unit (12) can control the power supply (11) to cut off the power supply to the second heater (B18) if the cartridge (B19) is not coupled to the body (B10).

[0127] When the stick (S) is heated by the second heater (B18) without the cartridge (B19) being engaged, aerosol may be generated. However, when only the stick (S) is heated without the aerosol atomized in the cartridge (B19), a user who inhales only the aerosol generated by the stick (S) may experience a foreign sensation or discomfort.

[0128] In an aerosol generating device according to one embodiment of the present disclosure, when the cartridge (B19) is not coupled to the body (B10), the power supply to the second heater (B18) is cut off, thereby preventing a foreign sensation or discomfort that may be felt by the user.

[0129] Referring to Fig. 10, when the cartridge (B19) is coupled to the body (B10), the stick (S) can be received or inserted into the body (B10) by the user. The stick (S) can be inserted into the insertion space (B134) of the body (B10).

[0130] That is, the control unit (12) can control the power source (11) to supply power to the heater (B342) based on the stick (S) being accommodated in the body (B10) and the cartridge (B19) being coupled to the body (B10).

[0131] Accordingly, in a state where the stick (S) is accommodated in the body (B10) and the cartridge (B19) is determined to be coupled to the body (B10), power can be supplied to the heater (B342) to normally generate an aerosol.

[0132] Although not shown in Fig. 10, when the cartridge (B19) and the cap (B200) are coupled to the body (B10), the stick (S) can be received or inserted into the body (B10) by the user. The stick (S) can be inserted into the insertion space (B134) of the cartridge (B19) by passing through the insertion port (B214) while the door (215) of the cap (B200) is open.

[0133]

[0134] Fig. 11 is a cross-sectional view showing a state in which a cartridge is coupled in an aerosol generating device according to another embodiment of the present disclosure. Any features that overlap with the descriptions provided with reference to Figs. 6 to 10 will be omitted for brevity.

[0135] Referring to FIG. 11 together with FIG. 6, the aerosol generating device (1) may include a body (C10) and a cartridge (C19). The cartridge (C19) may be coupled to one side of the body (C10).

[0136] The sensor (138) may be placed on one side of the body (C10). The sensor (138) may be placed on the upper side of the body (C10) where the cartridge (C19) is coupled to the body (C10). When the cartridge (C19) is coupled to the body (C10), the sensor (138) may face the cartridge (C19).

[0137] The control unit (12) can receive a signal output by the sensor (138). Based on the signal output by the sensor (138), the control unit (12) can determine whether an object is received or approached by the body (C10).

[0138] The control unit (12) can determine whether to couple the cartridge (C19) to the body (C10) based on whether an object is received in or close to the body (C10).

[0139] The control unit (12) can determine whether the cartridge (C19) is coupled to the body (C10) via the power supply terminal (C428). The power supply terminal (C428) can be arranged on the upper surface of the body (C10). The power supply terminal (C428) can be electrically connected to the power source (11). When the cartridge (C19) is coupled to the body (C10), the power supply terminal (C428) can come into contact with the connection terminal (C231) provided in the cartridge (C19). The power supply terminal (C428) can be electrically connected to a heater (C242) (e.g., heater (24)) via the connection terminal (C231). The heater (C242) can wind a wick (C241) (e.g., liquid delivery means) or can be in contact with one side of the wick (C241). The wick (C241) can be impregnated with an aerosol production material of the storage unit (C0). The heater (C242) heats the wick (C241) so that an aerosol can be generated.

[0140] The control unit (12) can control the power supply (11) so that a predetermined current is applied through the power supply terminal (C428) based on whether an object is received or is in proximity to the body (C10). The control unit (12) can determine whether or not to engage the cartridge (C19) based on whether or not a current corresponding to the predetermined current is received through the power supply terminal (C428).

[0141] Referring to Fig. 11, an object accommodated in or approaching a body (C10) may be a cartridge (C19). That is, when the acceptance or approach of an object to the body (C10) is detected by the sensor (138), the control unit (12) can determine, via the power supply terminal (C428), whether the object is a cartridge (C19).

[0142] The control unit (12) can control the power supply (11) to cut off the current supply to the power supply terminal (C428) based on whether the object is not received or is not in proximity. That is, the control unit (12) determines whether the object is received or in proximity through the sensor (138), and can determine whether the cartridge (C19) is engaged through the power supply terminal (C428) only when it determines that the object is received or in proximity to the body (C10).

[0143] Accordingly, unnecessary power waste can be prevented to check whether the cartridge is combined.

[0144]

[0145] Fig. 12 is a block diagram of an aerosol generating device (1) according to one embodiment of the present disclosure.

[0146] 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. 12. 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. 12 may be omitted or new components may be added.

[0147] 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.

[0148] 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).

[0149] 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.

[0150] 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).

[0151] 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.

[0152] A temperature sensor (131) is placed inside the body (10) and can detect the internal temperature of the body (10).

[0153] 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.

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.

[0190] 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.
