Electronic cigarette and heating wire thereof

Abstract

The invention relates to an electronic cigarette and a heating wire thereof. The heating wire comprises the following components in percentage by mass: 46-78% of nickel, 0.005-0.4% of cerium and the balance of iron. The heating wire can reduce the temperature increase speed when in use.

Description

technical field [0001] The invention relates to an electronic cigarette, in particular to a heating wire in the electronic cigarette. 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 an output voltage between 4.15 and 4.25V as the power supply, and control the output voltage of the power supply through a 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, and 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 voltage; ...

AI Technical Summary

Problems solved by technology

[0004] In existing electronic cigarettes, since the voltage applied to both ends of the heating wire is a constant voltage or can only change with the voltage of the lithium battery, the longer the smoking time, the higher the temperature of the heating wire will be. When the temperature of the heating wire exceeds the vaporization temperature of the e-liquid When the e-liquid is cracked, it will produce a burnt smell
