Fig. 4 shows an initial current distribution and a temperature change in the bobbin space according to an example.
According to an embodiment, a user of the electronic device 100 may use a first aerosol-generating substrate (e.g., a first cigarette) to make a first puff. For example, the first puff may be a first puff performed in an idle state of the electronic device 100 or a puff after a substantial time from the last puff.
The control part 210 may supply current to the heating part 220 based on the initial current profile 410. For example, the initial current profile 410 may have a maximum current value I for instantaneous temperature rise m And may have a constant current value I for maintaining a constant temperature s . Can be at peak time t p1 Internal holding maximum current value I m . The user can at time point t e Ending the first smoking. For example, the user may control the electronic apparatus 100 to stop supplying power or current to the heating part 220.
According to an embodiment, the temperature sensor of the sensor part 240 may monitor the temperature of the bobbin space. The first temperature profile 421 represents the bobbin space temperature during the first puff. Although the first temperature profile 421 in the drawing starts from the origin, the origin may refer to the temperature at the point of time at which the monitoring of the temperature starts. The temperature in the bobbin space is rapidly raised based on the initial current profile 410After warming, can be maintained at a constant level (e.g., temperature T m ). Can be performed during a first period of time (time 0 to time t e ) And performing first smoking.
According to an embodiment, when the first smoking ends, the temperature of the bobbin space may decrease since no current is supplied to the heating part 220. The second temperature curve 422 represents a decreasing temperature. For example, the second curve 422 may last for a second period of time (point in time t e By time point t 1 )。
According to an embodiment, the temperature of the cartridge space may further decrease when the user removes the first aerosol-generating substrate from the insert part 230. The third temperature curve 424 represents the decreasing temperature. For example, the third curve 424 may last for a third period of time (point in time t 1 By time point t 2 )。
According to an embodiment, when a user inserts the second aerosol-generating substrate into the insert portion 230 to begin continuous smoking, the temperature of the bobbin space may further decrease as the second aerosol-generating substrate may absorb heat in the bobbin space. A fourth temperature curve 426 represents a decreasing temperature. For example, the fourth curve 426 may last for a fourth period of time (point of time t 2 By time point t 3 )。
According to an embodiment, the second aerosol-generating substrate may absorb a portion of the heat within the cartridge space, which may be considered to have been heated before the heating portion 220 is operated. Therefore, the control part 220 can reduce the current supplied to the heating part 220 at the time of the second smoking compared to the time of the first smoking. For example, the control part 220 may calculate a current compensation value based on the heat absorbed by the second aerosol-generating substrate and generate a current distribution reflecting the calculated current compensation value. In this regard, a method of controlling the current supplied to the heating portion will be described in detail with reference to fig. 5 to 6.
Fig. 5 is a flowchart of a method of controlling a current supplied to a heating portion according to an embodiment.
The following steps 510 to 550 may be performed by the electronic device 100 described above with reference to fig. 1 to 4.
In step 510, the control part 210 may supply power to the heating part 220 based on a preset initial current profile (e.g., initial current profile 410 of fig. 4). For example, the control portion 210 may supply current to the heating portion 220 to perform the first puff. The user may be able to select the first time period (e.g., time point 0 to time point t in fig. 4) e ) Smoking is performed on a first aerosol-generating substrate inserted into the electronic device 100.
In step 520, the control portion 210 may monitor the temperature of the space in which the first aerosol-generating substrate is located (e.g., the bobbin space) after the first puff is completed (or ended). The temperature monitoring results of the bobbin space may be represented as a second temperature profile 422, a third temperature profile 424, and a fourth temperature profile 426 described with reference to fig. 4.
According to an embodiment, the control portion 210 may determine whether the first aerosol-generating substrate has been removed based on the monitoring result. For example, when the second temperature profile 422 occurs, it may be determined that the first aerosol-generating substrate has been removed.
According to an embodiment, the control portion 210 may determine whether to insert new aerosol generation based on the monitoring result. For example, when the third temperature profile 424 occurs, then it may be determined that a new aerosol-generating substrate (e.g., a second aerosol-generating substrate) is inserted. The third temperature profile 424 occurs for the temperature of the bobbin space because the new aerosol-generating substrate absorbs some of the heat in the bobbin space. Based on the monitoring results, a first point in time of insertion of a new aerosol-generating substrate may be determined.
According to an embodiment, the temperature of the spool space may be monitored for a preset time (e.g., 60 seconds). After the preset time is reached, monitoring of the temperature of the bobbin space may be stopped. According to another embodiment, when the measured temperature of the spool space decreases to a preset threshold temperature (e.g., temperature T of FIG. 4 th ) In the following, monitoring of the temperature of the bobbin space may be stopped. When stopping the temperature monitoring, the following step 530 may not be performed. Smoking that occurs after cessation of temperature monitoring will not be considered continuous smoking.
In step 530, heating of the new aerosol-generating substrate is initiatedWhen (e.g., from t of FIG. 4) 3 Initially), the control portion 210 may calculate the current compensation value based on the temperature change of the bobbin space. For example, the current compensation value may be calculated based on a first point in time at which a new aerosol-generating substrate is inserted and a second point in time at which heating of the new aerosol-generating substrate is started.
According to an embodiment, the time point t can be based on 2 Temperature T at 2 And time point t 3 Temperature T at 3 The difference between them to calculate the compensation heat. For example, the specific heat of the material, the mass of the material, and the temperature change (e.g., (T) 3 -T 2 ) To calculate the compensation heat. The specific heat of the material and the mass of the material may be preset according to the inserted aerosol-generating substrate. Thus, the control part 210 may calculate the compensation heat based on the temperature change.
According to an embodiment, the control part 210 may calculate the current compensation value based on the compensation heat. For example, in order for the heating part 220 to generate the calculated compensation heat, the total amount of current supplied to the heating part 220 may be calculated as a current compensation value.
In step 540, the control part 210 may adjust the initial current profile based on the current compensation value, thereby generating a compensation current profile. For example, the peak time t of the initial current distribution can be calculated by p1 The time corresponding to the current compensation value is shortened to generate a compensation current distribution. For example, the control unit 210 may use the maximum current value I m A target shortening time corresponding to the current compensation value is determined. From the peak time t p1 The time obtained by subtracting the target shortening time can be the new peak time t of the compensation current distribution p2 . In this regard, the compensation current distribution will be described in detail with reference to fig. 6.
In step 550, the control part 210 may control the current supplied to the heating part 220 based on the compensation current profile. The user may make a second puff based on the compensated current profile.
Fig. 6 shows a compensation current distribution and a temperature change in the bobbin space according to an example.
According to one embodiment, after the first puff described with reference to figure 4,the user may then follow from the point in time t 3 A second puff is initiated. For example, time point t 3 It may be a time when the user activates the heating part 220. For example, at time point t 3 The measured temperature of the bobbin space of (2) may be T 3 。
According to an embodiment, the control portion 210 may generate the compensation current profile 610 for the second puff when the second puff is initiated. For example, the control unit 210 measures a fourth time period (time point t 2 To time point t 3 ) Calculates a current compensation value and reflects the current compensation value by modifying the initial current profile, thereby generating a compensated current profile 610. For example, the control unit 210 may shorten the output maximum current value I in the initial current distribution m Peak time t of (2) p1 To correspond to the current compensation value. For example, the compensation current profile 610 may have an output maximum current value I m Peak time t of (2) p2 。
The heating portion 220 may heat the new aerosol-generating substrate with the current supplied based on the compensation current profile 610. The temperature profile 621 may represent the temperature of the bobbin space during the second puff. The user can at time point t 4 The heating portion 220 is deactivated to terminate the second puff.
Although not shown, similar to fig. 4, at time point t 4 The temperature of the bobbin space can then also be monitored. When the third smoking is further continued after the second smoking, a compensation current distribution for the third smoking can be generated.
