Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a flowchart of a heating control method of an embodiment of a heating non-combustion apparatus of the present invention, the heating control method of the embodiment comprising the steps of:
step S10, when a tobacco medium is heated in a microwave heating mode, detecting the frequency of a microwave signal in real time, and determining an initial time point corresponding to the tobacco medium reaching a specific temperature according to the frequency detected in real time;
step S20, determining the required energy of the tobacco media from the initial time point according to the specific temperature and a preset target temperature (for example, 225 ℃);
and step S30, controlling the output power and/or the output time of the microwave source unit according to the required energy so as to enable the temperature of the tobacco media to reach the target temperature.
In this example, in the environment where the tobacco medium is heated by microwaves, the temperature of the tobacco medium increases (for example, the temperature increases from room temperature), which causes a change in the dielectric constant of the tobacco medium, and the real part of the dielectric constant is the actual dielectric constant, which further affects the wavelength of the electromagnetic wave. Also, since the wavelength of electromagnetic waves is inversely proportional to frequency, a real part variation in dielectric constant affects a variation in frequency of a microwave signal. For a certain heating nonflammable device, the tobacco medium installed in the heating nonflammable device is determined to have a unique specific temperature, and the specific temperature corresponds to a unique microwave signal frequency, so that the time point (initial time point) when the tobacco medium reaches the specific temperature can be determined by detecting the frequency of the microwave signal in real time. When the specific temperature of the tobacco medium is determined, the energy (required energy) required to be provided for the tobacco medium from the initial time point can be determined by combining the target temperature, and finally, the output power and/or the output time of the microwave source unit can be controlled according to the required energy so as to enable the temperature of the tobacco medium to reach the target temperature.
In this embodiment, since the initial time point corresponding to the time when the tobacco medium reaches the specific temperature can be determined according to the frequency detected in real time, that is, the temperature (specific temperature) of the tobacco medium at the initial time point is detected, when the temperature of the tobacco medium is measured, it is no longer necessary to install a temperature measuring device such as a thermistor in the heating non-combustion device, and it is also no longer necessary to provide a protruding portion for accommodating the thermal temperature measuring device on the heating non-combustion device, so that the work of cleaning the protruding portion periodically can be omitted for a user, not only improving the user experience, but also avoiding the damage of the protruding portion caused by cleaning.
Further, in an alternative embodiment, the heating control method of the present invention further includes:
calculating the output energy of the microwave unit from the initial time point to the current time point according to the real-time output power and output time of the microwave source unit in the process that the temperature of the tobacco medium reaches the target temperature;
determining the temperature of the tobacco medium at the current time point according to the output energy and the specific temperature;
judging whether the calculated temperature at the current time point is consistent with the set temperature at the current time point in a preset temperature curve;
and when the output power and/or the output time of the microwave source units are inconsistent, adjusting the output power and/or the output time of the microwave source units.
In this embodiment, in the process from the initial time point (the time point when the tobacco medium reaches the specific temperature) to the time point when the tobacco medium reaches the target temperature, the temperature of the tobacco medium at the current time point can also be reversely deduced from the already output energy (output energy), specifically: since the output power and the output time in the period from the initial time point to the current time point are determined, the output energy that has been output can be calculated from the output power and the output time. The output energy is related to the temperature difference in the period from the initial time point to the current time point, so the temperature at the current time point can be calculated according to the output energy and the specific temperature. And then comparing the calculated temperature with the set temperature of the corresponding time point in the temperature curve, and if the calculated temperature is inconsistent with the set temperature of the corresponding time point in the temperature curve, adjusting the output of the microwave source unit to ensure that the actual estimated temperature of the tobacco medium is consistent with the temperature curve, thereby ensuring the quality of sucking taste and aerosol. Moreover, according to the embodiment, the temperature measurement of the tobacco media is realized through a software calculation method, and the accuracy is high through testing, as shown in fig. 2, a curve L1 is a temperature curve calculated by using the temperature measurement mode of the embodiment, and a curve L2 is a measured temperature curve.
Further, the temperature of the tobacco medium at the current point in time may be determined by: 1. adopting a formula calculation mode; 2. and adopting a table look-up mode. In this embodiment, a relational expression of energy and temperature or a relational table of energy and temperature difference (a difference between a temperature at a current time point and a specific temperature) may be stored in advance, and after the energy that has been output is calculated, the temperature at the current time point may be calculated by the relational expression of energy and temperature, or the temperature at the current time point may be obtained by looking up the relational table of energy and temperature difference.
Further, when the output power and/or the output time of the microwave source unit are inconsistent, the method may specifically include:
comparing the calculated temperature at the current time point with the set temperature at the current time point in a preset temperature curve;
if the calculated temperature at the current time point is greater than the set temperature, controlling the microwave source unit to reduce the output power and/or reduce the output time;
and if the calculated temperature at the current time point is smaller than the set temperature, controlling the microwave source unit to increase the output power.
In this embodiment, when comparing the calculated temperature at the current time point with the set temperature at the current time point in the preset temperature profile, the following three comparison results may occur: 1. the calculated temperature is larger than the set temperature, which indicates that the actual temperature of the tobacco media is too high, and the output power of the microwave source unit can be reduced and/or the output time can be reduced at the moment; 2. the calculated temperature is smaller than the set temperature, which indicates that the actual temperature of the tobacco medium is too low, and the output power of the microwave source unit can be improved at the moment; 3. the calculated temperature is equal to the set temperature, which indicates that the actual temperature of the tobacco media is just suitable, and no adjustment of the output power and/or the output time is needed.
Further, in an optional embodiment, in step S10, determining, according to the frequency detected in real time, an initial time point corresponding to when the tobacco medium reaches the specific temperature includes:
determining inflection point frequency according to the frequency detected in real time, and taking a time point corresponding to the inflection point frequency as an initial time point;
the temperature of the tobacco medium at the initial point in time is determined as the specific temperature.
Further, the corner frequency may be determined according to the following manner: and taking the maximum frequency in the frequencies detected in real time as the inflection point frequency. It should be noted that after the follow-up frequency detection, the detected frequencies may be ranked to find the maximum value, which is the inflection point frequency; the detected frequencies can also be made into a frequency curve according to time, and the curve is obviously a parabola with a downward opening, and the maximum value of the parabola is the inflection point frequency.
In this embodiment, as shown in table 1, in the environment where the tobacco medium is heated by microwaves, as the temperature of the tobacco medium increases, the real part of the dielectric constant of the tobacco medium increases gradually and then decreases gradually, and the real part of the dielectric constant affects the wavelength of the electromagnetic wave, and the wavelength of the electromagnetic wave is inversely proportional to the frequency, so that the change of the real part of the dielectric constant affects the change of the frequency of the microwave signal, and the inflection point of the frequency corresponds to the inflection point of the change of the real part of the dielectric constant of the tobacco medium, that is, 3.85, and the temperature (specific temperature) corresponding to the inflection point of the change of the real part of the dielectric constant is determined to be 100 ℃, so that the temperature at the moment when the inflection point of the frequency occurs can be determined as the specific temperature.
