Technical field

[0001] The present invention relates to the technical field of ignition devices, in particular to an ignition device and a cigarette lighter.

Background technique

[0002] 5 See that when some arc ignition devices are turned on, the high-voltage package outputs two wires to form an arc line

Therefore, when the cigarette is lighted, the burning surface is very small, and the end surface of the cigarette is often burned, which is inconvenient to use.

[0003] In order to increase the combustion area, a number of wires have been developed to form several arc lines, or are arranged in cross or parallel, but the actual combustion surface is still an area composed of dotted arc lines, and multiple wires have not actually increased much. It only increases the intensity of the arc and accelerates the burning speed.
