Description
Technical Field
The invention relates to the technical field of tobacco heating, in particular to a temperature control method of a device which does not burn tobacco when being heated.
Background
In the field of tobacco appliances which are not burnt during heating, the temperature of the heating body for heating tobacco determines the quality of smoke, and further has great influence on the using effect of users. Temperature control always has a high concern in the industry, and the temperature of a heating body is required to be accurately controlled at present with great difficulty.
The existing temperature control method for heating and non-burning mainly comprises the following steps:
one is to add an independent temperature measuring element, such as a thermistor or a thermocouple, near one point of the heating area of the heating element by embedding or sticking. The temperature is controlled to approach the target temperature by collecting temperature information through a measuring resistance circuit or a thermocouple measuring circuit and a microcontroller and then controlling the on-off time ratio of the power switch device at a high speed.
The other is a heating element device with resistance value obviously changing with the temperature change, and usually has a Positive Temperature Coefficient (PTC) heating element and a Negative Temperature Coefficient (NTC) heating element. Similarly, the temperature is controlled to approach the target temperature by acquiring temperature information through the measuring resistor circuit and the microcontroller and then controlling the on-off time ratio of the power switch device at a high speed.
For the prior art, certain defects exist.
The temperature can be measured and then controlled by adding a thermistor or a thermocouple, but a single temperature measuring device can only measure the temperature of one point part and cannot reflect the overall temperature condition. If the measuring position is increased, the operation complexity of the temperature measuring device, the related circuit and the microcontroller is increased. And either a single or multiple thermometric devices can incur production costs beyond the heating element.
The effect of measuring and controlling the temperature can be achieved by using the heating element with positive temperature coefficient or negative temperature coefficient. However, the type selection of the heating element is less, and the cost is higher. And the resistance temperature coefficients of all the heating elements of the same type have certain discreteness although the processes are consistent, and the temperature accuracy brought by the temperature control by the method is still not very accurate.

The heat will generate heat and heat the tobacco according to joule's law. In addition, in order to make the tobacco at the proper temperature for volatilizing the smoke, the temperature of the heating element needs to be controlled, so that the temperature of the heating element is not too high to burn the tobacco and is not too low to generate the smoke.

and step 120, adjusting the temperature of the heating element by adjusting the on-off time ratio of the switching element based on the power of the heating element.

Specifically, in some embodiments, a power switching device (e.g., a field effect transistor) may be used to connect a power source, such as a lithium battery, and a heat generating body as a conducting path for power output. And meanwhile, a current measuring module is connected in series in the loop and used for measuring the current flowing through the heating element, and a voltage measuring module for measuring the voltage of the heating element is designed beside the heating element. In the conducting stage of the power switch device, the measured current and voltage data are transmitted to the microcontroller for operation, and preferably, multiple groups of data can be measured in the conducting stage of one power switch device for calculation and power average value taking.

For example, the specific power measurement and calculation is: if the voltage V is measured and the current I is measured, the power is the voltage multiplied by the current, namely the calculated power P is V I.

And simultaneously, a module for measuring the voltage of the heating element and a module for measuring the resistance of the heating element are designed beside the heating element. In the conducting stage of the power switch device, the measured voltage and resistance data are transmitted to the microcontroller for operation, and necessarily, multiple groups of data can be measured in the conducting stage of one power switch device for calculation and power average value is obtained.
Corresponding to the power measurement module structure shown in fig. 4, in some embodiments, the determining the power of the heat generating body based on the data acquired by the power measurement module includes:

For example, during a time period t1, the microcontroller makes the power switch always conductive, and the power is measured by the aforementioned power value measurement method while outputting the power. For a time period t2, the power switch is always off. t1 and t2 make one of t1 and t2 constant and the other constant according to the corresponding relation of stored power, on-off time proportion and temperature.
In some embodiments, the method further comprises the step of setting one of t1 and t2 to be a constant value according to the corresponding relation among power, on-time, off-time ratio and temperature; another value to be adjusted includes:

If t1 is set to be a fixed value
If t2 is set to be a fixed value
In the two temperature control methods, the total time for completing one on time and one off time is short, and the temperature value is stable in a macroscopic view.
In some embodiments, the corresponding relationships K1 and K2 of power, on-time and off-time ratios and temperature are obtained by collecting multiple sets of related data based on multiple appliance operation experiments.

The control method is simpler, and the selection of the heating element is wider.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
