Abstract

The invention relates to a low-power-consumption intelligent arc lighter and an ignition method. The low-power-consumption intelligent arc lighter comprises a power supply component, a triode controlled semi-harmonic high-frequency oscillating circuit, a high-frequency arc ignition pair and an MCU (microcontroller unit), and a connection relation of the power supply component, the semi-harmonic high-frequency oscillating circuit, the high-frequency arc ignition pair and the MCU is displayed in a diagram of the abstract. The triode controlled semi-harmonic high-frequency oscillating circuit comprises a power field-effect transistor switch, a triode, a rectifier diode, a feedback resistor, a voltage stabilizing capacitor and a boosting transformer. The boosting transformer comprises a primary winding, a secondary winding and a positive feedback winding. The power supply component comprises a lithium battery, a constant-current constant-voltage linear charging chip of the single lithium battery and two LED (light emitting diode) indicating lights. On the basis of an existing arc lighter, the MCU is arranged additionally to realize intelligent control of charging and discharging processes of the circuit, monitoring of conditions of the lithium battery is realized, and a user can be prompted through the LED indicating lights. The low-power-consumption intelligent arc lighter has the advantages of low power consumption, intelligence, simple structure, high safety, energy saving, environment friendliness and the like.

Description

technical field [0001] The invention relates to the field of arc lighters, which are powered by a lithium battery, charged by a USB interface, and controlled by an MCU (microcontroller), and in particular relate to a low-power consumption intelligent arc lighter circuit and a lighting method. Background technique [0002] Lighter is a small fire-making device, mainly used for smoking and making fire, but also for cooking and other fire-making. The main components of the lighter are the ignition mechanism and the gas storage tank. When the ignition mechanism operates, sparks burst out and shoot to the gas area to ignite the gas. According to the characteristics of the firing mechanism, lighters can be divided into flint steel wheel lighters, piezoelectric ceramic lighters, magnetic induction lighters, battery lighters, solar lighters, and microcomputer lighters. Flint steel wheel lighters have high calorific value and high ignition rate. The disadvantages are that the operat...

AI Technical Summary

Problems solved by technology

Flint steel wheel lighters have high calorific value and high ignition rate. The disadvantages are that the operation is not brisk enough and the flint steel wheel is easy to wear

Piezoelectric ceramics and magnetic induction lighters have disadvantages such as short discharge time and low ignition success rate

And the above-mentioned traditional types of lighters all use fuel oil or gas as energy, and combustion will produce waste gas, which is not energy-saving and environmentally friendly.
