As an example, the external heating heater 520 may be an induction heater. When the external heating heater 520 is the induction heater, the heat conductive wrapper 530 of the aerosol generating article 510 may conduct heat generated by the susceptor.

As an example, the identification sensor 611 may be a sensor that generates a magnetic field signal of a constant frequency and reads a frequency signal of a magnetic field that is reflected back from the aerosol generating article 620. As another example, the identification sensor 611 may be a sensor that distinguishes an external color of the aerosol generating article 620 or a shape such as a band formed on the aerosol generating article 620. As another example, the identification sensor 611 may also be configured to detect reflection, refractive index, or transmittance of light.

The heater 810 illustrated in
Referring to
To adjust quality (e.g., tastes or amount of vapor) of aerosol, the aerosol generating device 800 may operate according to a preset temperature heating condition (i.e., a temperature profile). In general, a temperature profile is uniformly applied in one uniform pattern to prevent a sensory difference in an aerosol from being generated due to variations between aerosol generating devices 800, variations between aerosol generating articles 850, or the like.
Referring to
For example, the aerosol generating device 800 may select a temperature profile by using a sensing value of the temperature and humidity sensor 820 or may select a temperature profile by using weather information received from an external device 860.
Also, the aerosol generating device 800 may switch to another temperature profile in consideration of atmospheric pressure, temperature, humidity, and the like of a current location. For example, the aerosol generating device 800 may check location information of a user and accurately recognize weather information of the user's location based on the location information. Therefore, the aerosol generating device 800 may switch to another temperature profile based on the recognized weather information.
For example, the aerosol generating device 800 may select one temperature profile from among a plurality of temperature profiles according to temperature and/or humidity detected by the temperature and humidity sensor 820.
Table 1 is a table for explaining a process in which the controller 830 determines a temperature profile for the heater 810. Referring to Table 1, a memory of the aerosol generating device 800 may store criteria for distinguishing high temperature, room temperature, and low temperature and a criterion for distinguishing high humidity, normal humidity, and low humidity. For example, the controller 830 may further subdivide temperature and humidity, and in that embodiment, the number of temperature profiles generated by combinations of temperature and humidity may be more than nine. The controller 830 may check a sensing result from the temperature and humidity sensor 820, and determine which criterion is the closest to external temperature and/or humidity of the aerosol generating device 800. Therefore, the controller 830 may select an appropriate temperature profile from among a plurality of pre-stored temperature profiles. For convenience of description, Table 1 shows that the pre-stored temperature profiles are mapped to combinations of temperature and humidity, but are not limited thereto. In other words, pre-stored temperature profiles may be mapped only to an external temperature or may be mapped only to external humidity.
The controller 830 may finely adjust a preset temperature profile on the basis of temperature and/or humidity detected by the temperature and humidity sensor 820.
Table 2 is a table showing an example of a plurality of fine adjustment units that are output from the aerosol generating device 800. In detail, Table 2 shows nine fine adjustment unit groups. For example, the controller 830 may select one from among pre-stored temperature profiles as shown in Table 1, according to an external temperature detected by the temperature and humidity sensor 820. Also, the controller 830 may finely adjust the selected temperature profile according to Table 2, based on external humidity detected by the temperature and humidity sensor 820. In addition, the user may adjust or select a temperature profile through the aerosol generating device 800.
Also, the aerosol generating device 800 may record smoking history for each location, temperature profile information selected at a corresponding location, and the like, thereby constituting a preset data collection (i.e., big data). Therefore, the aerosol generating device 800 may acquire the best temperature profile information applied to the aerosol generating article 850 in various situations and learn on the basis of the acquired information. As a result, when the user moves to a new area or latest weather information in the user's area cannot be acquired, the best temperature profile may be selected or a temperature profile may be adjusted, based on data stored in the aerosol generating device 800 and a sensing result from the temperature and humidity sensor 820 of the aerosol generating device 800.
Also, the aerosol generating device 800 may include a plurality of temperature sensors and check whether or not the aerosol generating device 800 is overheated according to a temperature detected by the temperature sensors.

As illustrated herein, it is assumed that the heater 910 is arranged above the battery 920, and a long portion of a PCB (Printed Circuit Board) 950 is arranged to face a front of the battery 920. However, the location relationship between the elements may be different according to embodiments.
The heater 910 illustrated in
The battery 920 may supply power to the heater 910 and may be arranged such that a top surface thereof faces a lower side of the heater 910. Although not shown in
The PCM 925 may be arranged adjacent to the top surface of the battery 920. The PCM 925 is a circuit for protecting the battery 925 and may prevent overcharging or overdischarging of the battery 920. Also, the PCM 925 may prevent overcurrent from flowing into the battery 920 and cut off connections when a circuit connected to the battery 920 is short-circuited.
The first thermistor 930 is a resistor of which resistance is sensitively changed due to a temperature change and may be used to sense a temperature. The first thermistor 930 may be electrically connected to the PCM 925 arranged on the top surface of the battery 920, and information measured by the first thermistor 930 may be transmitted to the PCB 950 through the PCM 925.
The first thermistor 930 may be arranged adjacent to a front or rear surface of the battery 920. For example, as illustrated in
The second thermistor 940 may be arranged between the heater 910 and the battery 920. A space between the heater 910 and the battery 920 corresponds to a portion having the highest temperature in the aerosol generating device 900, and thus corresponds to an appropriate portion for determining an overall overheating state of the aerosol generating device 900. At least a portion of the PCB 950 may extend across the space between the heater 910 and the battery 920, and the second thermistor 940 may be arranged adjacent to the at least portion of the PCB 950 extending across the space between the heater 910 and the battery 920.
The PCB 950 may determine whether or not the aerosol generating device 900 is overheated, on the basis of temperatures measured by the first thermistor 930 and the second thermistor 940. When the aerosol generating device 900 is determined as being overheated, the PCB 950 stand by until overheating is released, and then automatically perform a heating operation using the heater 910.
The temperature sensor 960 may be arranged adjacent to the heater 910 to directly or indirectly measure a temperature of the heater 910. The heater 910 is a portion most affecting a cigarette inserted into the aerosol generating device 900, and characteristics of the aerosol generated from the cigarette may be changed according to the temperature of the heater 910. The aerosol generating device 900 according to the present embodiment may determine whether or not the aerosol generating device 900 is overheated, on the basis of the temperature of the heater 910 measured by the temperature sensor 960. Therefore, if hardware components inside the aerosol generating device 900 is not expected to be damaged by additional heating operation but the additional heating operation is expected to adversely affect the characteristics of the aerosol generated from the cigarette, the aerosol generating device 900 may be determined as being overheated.
The temperature and humidity sensor 970 may be arranged in the vicinity of a bottom surface of the battery 920 to measure temperature or humidity. The vicinity of the bottom surface of the battery 920 is a portion that is least affected by the heater 910, and thus may have a similar temperature to an external housing constituting an exterior of the aerosol generating device 900. The aerosol generating device 900 according to an embodiment may determine whether or not the aerosol generating device 900 is overheated, on the basis of a temperature of the vicinity of the bottom surface of the battery 920 measured by the temperature and humidity sensor 970. Therefore, the aerosol generating device 900 may determine, as an overheating state, a state in which external temperature is excessively high.
The PCB 950 may determine whether or not the aerosol generating device 900 is overheated, on the basis of temperatures measured by at least two of the first thermistor 930, the second thermistor 940, the temperature sensor 960, and the temperature and humidity sensor 970. As described above, the aerosol generating device 900 according to an embodiment may determine an overheating state thereof by comprehensively considering possibility of damage to hardware components inside the aerosol generating device 900, the characteristics of the aerosol generated from the cigarette, possibility of occurrence of safety issues due to the external temperature, and the like. Therefore, the aerosol generating device 900 may be maintained in the best state.
The aerosol generating device 900 may be connected to an external device through a wireless communication method and may be controlled through an application installed in the external device.
