Description

Technical Field

[0001] The utility model relates to the field of electronic ignition, in particular to an integrated ignition ignition device. Background Art

[0002] In the prior art, common ignition needle devices are generally composed of high-voltage ignition needles (spark plugs) and flame sensing needles. Such ignition needles are not provided with gas pipelines for ignition and ignition, and are generally direct ignition structures. When the power of the burner increases, according to the current "Technical Conditions for Liquid and Gas Fuel Burners for Boilers (GB / T-36699-2018)" standard, burners with a power greater than 400KW must have ignition and ignition functions to avoid possible safety hazards. The high-voltage electricity provided by the ignition transformer between the electronic ignition needle and the ground needle of the ignition-type ignition device produces an electric spark, and the gas or air-gas mixture is sprayed in through the gas pipe, and the gas is ignited by the electric spark. Some of the existing ignition-type ignition devices are split, and the high-voltage electric sparks generated by some common ignition-type ignition devices during ignition may be within the coverage of the sprayed gas and cannot contact the air, which can easily lead to ignition failure.

[0003] Therefore, it is necessary to provide a new technical solution. Utility Model Content
