Electronic cigarette and its control method

Abstract

The invention provides an electronic cigarette and a control method thereof. The electronic cigarette includes a heating wire assembly for generating heat, and the heating wire assembly includes a heating wire whose resistance value changes with temperature; a power supply is used for providing voltage to the heating wire assembly; And the controller, electrically connected to the heating wire assembly and the power supply, used to control the output voltage of the power supply, the controller includes a temperature detection module, used to detect the resistance of the heating wire to obtain the real-time temperature of the heating wire assembly, the temperature detection module has a heating upper limit Temperature and heating lower limit temperature, when the real-time temperature is less than or equal to the heating lower limit temperature, the controller controls the power supply to output the first voltage, when the real-time temperature is greater than or equal to the heating upper limit temperature, the controller controls the power supply to output the second voltage, and the second voltage is lower than the first A voltage, when the real-time temperature is greater than the lower limit temperature of heating but lower than the upper limit temperature of heating, the controller controls the power supply to maintain the current output voltage. The electronic cigarette and the control method thereof of the present invention can ensure that the taste of each cigarette is consistent and save electricity.

Description

technical field [0001] The invention relates to an electronic product, in particular to an electronic cigarette and a control method thereof. Background technique [0002] E-cigarette is an electronic device that is powered by a battery. The internal detection module detects the movement of the airflow to determine whether it is in a smoking state, and operates the heating wire to vaporize the e-liquid to achieve the smoking effect. [0003] Common electronic cigarettes use a lithium battery with a delivery voltage between 4.15-4.25V as the power supply, and control the output voltage of the power supply through the control chip to make the heating wire generate heat. This kind of electronic cigarette generally adopts two control methods: the first is to output a constant voltage within a certain range, the voltage value can be 3.6V±0.15V or 3.4V±0.15V, when the lithium battery voltage drops to 3.3V or 2.75V , the control chip controls the power supply to stop output voltag...

AI Technical Summary

Problems solved by technology

[0005] Based on this, it is necessary to solve the problem that traditional electronic cigarettes tend to produce burnt taste due to excessive heating wire temperature, and the temperature of the heating wire is unstable, which leads to inconsistent tastes, and provide a method that can avoid the burnt taste of electronic cigarettes and ensure that every puff of cigarette E-cigarette with consistent taste and power-saving electronic cigarette and its control method
