Electronic cigarette and temperature control method thereof

Abstract

The invention relates to an electronic cigarette and a temperature control method thereof. The method comprises a power supply unit, a heating assembly, a temperature feedback assembly and a control unit; the power supply unit is used for supplying an operating voltage for the control unit and the heating assembly; the heating assembly is used for heating substances in the electronic cigarette andproviding an actual heating temperature; the temperature feedback assembly is used for providing a feedback parameter for a controller according to the actual heating temperature of the heating assembly; the control unit is used for controlling the heating power of the heating assembly according to the feedback parameter provided by the temperature feedback assembly, a preset target temperature and a pre-stored temperature control mapping table, so that the actual heating temperature and the preset target temperature are kept consistent by controlling the heating power of the heating assembly; and the temperature control mapping table is a mapping table in one-to-one correspondence between the actual heating temperature of the heating assembly and the feedback parameter provided by the temperature feedback assembly. Closed-loop control of the actual heating temperature is formed, and a more accurate heating temperature is provided.

Description

【Technical field】 [0001] The invention relates to the field of electronic technology, in particular to an electronic cigarette and a temperature control method thereof. 【Background technique】 [0002] E-cigarettes are electronic products that imitate cigarettes and have the same or similar appearance, smoke, taste and feel to cigarettes. It turns nicotine, etc. into steam by means of atomization and other means, for users to inhale. Traditional e-cigarettes atomize nicotine by heating. Different temperatures will make electronic cigarettes produce different tastes and smoke volumes, so temperature control in electronic cigarettes is particularly important. [0003] However, traditional electronic cigarettes use the resistance value of the oversampled temperature sensor, and then calculate the target temperature according to the functional relationship between the resistance value and the temperature. The functional relationship (1) is as follows: [0004] R1=R0*(1+K)*ΔT;...

AI Technical Summary

Problems solved by technology

[0009] Therefore, it can be seen that in traditional electronic cigarettes, the target temperature of the heating device is calculated, not measured. It is an open-loop temperature control method, so the error is large

At the same time, due to the various factors that cause errors, the individual differences in the errors of different products are also very large. These factors are not considered in the above control methods. Therefore, in mass production, it is even more difficult to control the heating of products accurately sex
