Electronic cigarette and control method thereof

Abstract

The invention provides an electronic cigarette and a control method thereof. The electronic cigarette comprises a heating wire assembly, a power source and a controller. The heating wire assembly is used for generating heat and comprises heating wires, wherein the resistance value of the heating wires changes along with the changes of temperatures. The power source is used for providing voltages for the heating wire assembly. The controller is electrically connected with the heating wire assembly and the power source and used for controlling the power source to output the voltages. The controller comprises a temperature detecting module which is used for detecting the resistance value of the heating wires to obtain the real-time temperature of the heating wire assembly, an upper limit heating temperature and a lower limit heating temperature are set in the temperature detecting module, the controller controls the power source to output a first voltage when the real-time temperature is smaller than or equal to the lower limit heating temperature and controls the power source to output a second voltage when the real-time temperature is larger than or equal to the upper limit heating temperature, the second voltage is smaller than the first voltage, and the controller controls the power source to keep outputting the current voltage when the real-time temperature is larger than the lower limit heating temperature and smaller than the upper limit heating temperature. The electronic cigarette and the control method thereof can ensure the taste consistency of the smoke of all times and save electric quantity.

Description

technical field [0001] The present invention relates to an electronic product, in particular to an electronic cigarette and a control method thereof. Background technique [0002] The electronic cigarette is an electronic device powered by a battery, and 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 effect of smoking. [0003] Common electronic cigarettes use lithium batteries with a shipping voltage between 4.15-4.25V as the power supply, and control the output voltage of the power supply through a control chip, so that the heating wire generates heat. This electronic cigarette generally adopts two control methods: the first one 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 When the control chip controls the power supply to...

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
