Taking the above heating process as an example, referring to fig. 4, a heating control method provided in an embodiment of the present application includes the following steps.
And S100, acquiring current environment parameters.
S101, determining heating parameters of at least one heating process according to the current environment parameters, wherein the heating parameters comprise temperature value parameters and/or time length parameters.
S102, heating the aerosol generating substance according to the determined heating parameters.
The temperature value parameter and/or the time length parameter of the heating process are/is flexibly adjusted by determining the current environment parameter, so that the method is adaptive to the current environment, the quality of aerosol is improved, and better smoking experience is provided for users.
The following first describes how a single environmental parameter affects the setting of the heating parameter, and then describes how a plurality of environmental parameters collectively affect the heating parameter.
In an embodiment, in conjunction with fig. 5, the environmental parameter comprises an environmental temperature, and determining a heating parameter for at least one heating process based on the current environmental parameter comprises:
judging a preset temperature interval corresponding to the current environment temperature;
and determining at least one temperature value parameter of the heating process according to the corresponding preset temperature interval, wherein for any two preset temperature intervals, the temperature value parameter corresponding to the higher preset temperature interval is lower.
I.e. the higher the current ambient temperature, the lower the one or more temperature value parameters in the heating process are set.
When the ambient temperature is lower, the temperature of each heating process is properly increased to adapt to the ambient temperature, and comfortable smoke quantity is generated; when the ambient temperature is higher, then suitably reduce the temperature in each stage, avoid the flue gas temperature too high to influence the suction experience.
For example, when the ambient temperature is 20 ℃ to 30 ℃, the first temperature threshold T1Set to 365 ℃, a second temperature threshold T2Set to 325 ℃, third temperature threshold T3Set to 315 deg.C, a fourth temperature threshold T4Set to 320 ℃, a fifth temperature threshold T5The temperature was set to 325 ℃. When the ambient temperature is above 40 ℃, the first temperature threshold value T1Set to 345 deg.C, a second temperature threshold T2Set to 305 ℃, a third temperature threshold T3Set to 295 deg.C, a fourth temperature threshold T4Set to 300 ℃, a fifth temperature threshold T5The temperature was set to 305 ℃. As the ambient temperature increases, the temperature thresholds tend to decrease.
In an embodiment, in conjunction with fig. 6, the environmental parameter comprises an environmental temperature, and determining a heating parameter for at least one heating process based on the current environmental parameter comprises:
judging a preset temperature interval corresponding to the current environment temperature;
and determining at least one time length parameter of the heating process according to the corresponding preset temperature intervals, wherein for any two preset temperature intervals, the time length parameter corresponding to the higher preset temperature interval is lower.
That is, as the ambient temperature increases, the duration of the partial heating process tends to decrease. This is because the higher the ambient temperature, the higher the temperature of the aerosol generated by the aerosol generating device and the temperature of the surface of the device, which is likely to cause burns without shortening the duration of the heating process.
The duration of the first heating process, i.e. the initial warming process, is relatively sensitive, and too long duration thereof easily causes the end temperature of the warming process to be higher than the set first temperature threshold T1. The seventh heating process and the ninth heating process are relatively sensitive in duration, and at this stage, the effective components of the smoking substance are few, the smoking substance is easy to scald due to too long duration, and the generated aerosol has poor taste. The duration of the pull-down process and the duration of the mid-stream temperature plateau have relatively little effect on pumping.
Referring to figure 6, when the ambient temperature is less than-10 ℃, the heating time of the aerosol-generating device is suitably increased to accommodate the ambient temperature, producing a comfortable amount of aerosol, and so t1Set to 18s, t7、t9Set to 30 s; when the ambient temperature is-10 ℃, t1Set to 15s, t7、t9Set to 25 s; t when the ambient temperature is 10-30 DEG C1Set to 12s, t7、t9Set to 20 s; when the ambient temperature is greater than 30 ℃, the heating time of the aerosol-generating device is suitably reduced, thus t1Set to 10s, t7、t9Set to 15 s.
In an embodiment, referring to fig. 7, the environmental parameter is ambient humidity, and the determining the heating parameter of at least one heating process according to the current environmental parameter includes:
judging a preset humidity interval corresponding to the current environment humidity;
and determining at least one temperature value parameter of the heating process according to the corresponding preset humidity intervals, wherein for any two preset humidity intervals, the temperature value parameter corresponding to the higher preset humidity interval is lower.
That is, as the ambient humidity increases, the heating temperature tends to decrease. When the environmental humidity is higher, the moisture content of the cigarettes is increased, so that the smoke temperature is increased, and the user experience is reduced, so that the temperature of each heating process is properly reduced; conversely, when the ambient humidity is low, the mouthfeel can be improved by appropriately raising the temperature of each heating process.
In particular, T is for example determined when the ambient humidity is between 40% and 70%1At 365 ℃, T2At 325 ℃ T3At 315 ℃ and T4At 320 ℃ and T5The temperature was 325 ℃. When the environmental humidity is 70-90%, T1At 355 ℃ C, T2At 315 ℃ and T3At 305 ℃ C, T4At 310 ℃ T5The temperature was 315 ℃.
In an embodiment, referring to fig. 8, the environmental parameter is ambient humidity, and the determining the heating parameter of at least one heating process according to the current environmental parameter includes:
judging a preset humidity interval corresponding to the current environment humidity;
and determining at least one time length parameter of the heating process according to the corresponding preset humidity interval, wherein the time length parameter corresponding to the higher preset humidity interval is lower.
That is, as the ambient humidity increases, the duration of some heating processes tends to decrease. The reduction of the heating time is advantageous for suppressing the rise of the temperature of the flue gas.
Specifically, t is when the ambient humidity is 40% -70%1Set to 12s, t7、t9Set to 20 s. When the ambient humidity is 70-100%, t1Set to 10s, t7、t9Set to 15 s.
In an embodiment, referring to fig. 9, the environmental parameter is altitude, and the determining of the heating parameter of at least one heating process according to the current environmental parameter comprises:
judging a preset altitude interval corresponding to the current altitude;
and determining at least one temperature value parameter of the heating process according to the corresponding preset altitude interval, wherein for any two preset altitude intervals, the temperature value parameter corresponding to the higher preset altitude interval is higher.
That is, as the altitude increases, the heating temperature tends to increase. As the altitude increases, the ambient temperature, humidity and air pressure should decrease accordingly, and therefore the temperature of each heating process should be raised appropriately so as to generate a sufficient amount of smoke; conversely, when the altitude is low, the temperature of each stage is appropriately lowered.
In particular, T is for example at an altitude of 0-1000m1At 365 ℃, T2At 325 ℃ T3At 315 ℃ and T4At 320 ℃ and T5The temperature was 325 ℃. When the altitude is above 3000m, T1At 395 ℃ and T2At 355 ℃ C, T3At 345 ℃ C, T4At 350 ℃ T5The temperature was 355 ℃.
In an embodiment, referring to fig. 10, the environmental parameter is altitude, and the determining of the heating parameter of at least one heating process according to the current environmental parameter comprises:
judging a preset altitude interval corresponding to the current altitude;
and determining the time length parameter of at least one heating process according to the corresponding preset altitude interval, wherein for any two preset altitude intervals, the time length parameter corresponding to the higher preset altitude interval is higher.
I.e. with an increasing altitude, a higher altitude and a relatively lower temperature, the duration of some heating processes tends to increase, thus ensuring a sufficient amount of smoke. When the altitude is higher, the heating time of the aerosol-generating device is suitably increased to produce a comfortable amount of smoke.
In particular, t is for example when the altitude is between 0 and 1000m1Set to 12s, t7、t9Was 20 s. When the altitude is above 3000m, t1Set to 21s, t7、t9Was 35 s.
In one embodiment, referring to fig. 11, the environmental parameter comprises air pressure, and determining a heating parameter for at least one heating process based on the current environmental parameter comprises:
judging a preset air pressure interval corresponding to the current air pressure;
and determining at least one temperature value parameter of the heating process according to the corresponding preset air pressure interval, wherein for any two preset air pressure intervals, the temperature value parameter corresponding to the higher preset air pressure interval is lower.
That is, as the air pressure increases, the overall heating temperature tends to decrease. The air pressure is high, the oxygen content is high, and the smoke amount is relatively large. When the air pressure is low, the temperature of each heating process is properly increased, so that the proper amount of smoke is generated; conversely, when the air pressure is higher, the temperature of each heating process is appropriately lowered.
Specifically, for example, when the air pressure is 70KPa or less, T1At 385 ℃ T2At 345 ℃ C, T3At 335 ℃ and T4At 340 ℃ T5It was 345 ℃. When the air pressure is 90-110KPa, T1At 365 ℃, T2At 325 ℃ T3At 315 ℃ and T4At 320 ℃ and T5The temperature was 325 ℃.
In one embodiment, referring to fig. 12, the environmental parameter is air pressure, and determining a heating parameter of at least one heating process according to the current environmental parameter includes:
judging a preset air pressure interval corresponding to the current air pressure;
and determining at least one time length parameter of the heating process according to the corresponding preset air pressure interval, wherein for any two preset air pressure intervals, the time length parameter corresponding to the higher preset air pressure interval is lower.
That is, as the pressure increases, the duration of some heating processes tends to decrease. When the air pressure is low, the heating time of the aerosol generating device is properly increased to generate comfortable smoke amount; when the air pressure is high, the heating time of the aerosol-generating device is suitably reduced to avoid scalding.
Specifically, for example, when the air pressure is 70KPa or less, t1Set to 18s, t7、t9Was 30 s. When the air pressure is 90KPa to 110KPa, t1Set to 12s, t7、t9Was 20 s.
All the above describes the effect of a single environmental parameter on a thermal parameter. When considering the influence of a plurality of environmental factors on the heating parameter, the setting may be performed as follows.
In one embodiment, the environmental parameter is a plurality of parameters, and determining a heating parameter of at least one heating process according to the current environmental parameter comprises:

and weighting and summing the plurality of alternative temperature values according to a preset proportionality coefficient, and using the sum as a temperature value parameter of the at least one heating process.

and weighting and summing the plurality of alternative time values according to a preset proportionality coefficient, and using the sum as a time length parameter of the at least one heating process.
The determination method of each alternative time value may refer to the aforementioned method of determining the time length parameter from a single environmental parameter.
Among the above four environmental parameters, the influence of the ambient temperature on the pumping experience is the largest, the influence of the ambient humidity on the pumping experience is the next, and the influence of the altitude and the air pressure on the pumping experience is the smallest. In a specific example, for a specific time duration parameter of a specific heating process, it is determined that the time duration parameter should be t based on the ambient temperaturei1Determining that the time length parameter should be t according to the ambient humidityi2It is determined from the altitude that the time length parameter should be ti3Determining from the air pressure that the time length parameter should be ti4The time length parameter t of the heating processiDetermined according to the following formula:
ti＝0.5ti1+0.3ti2+0.1ti3+0.1ti4equation (2).
It should be noted that, for the temperature value parameter and the time length parameter, the proportionality coefficients in the above two formulas may be the same or different.
