Description
Technical Field

Background
The burner is a generic term for a device that causes fuel and air to be ejected and burned in a fixed manner. The burner is divided into industrial burner, civil burner and special burner according to the type and application field. The burners commonly used in households include gas boilers, gas stoves, fierce fire gas stoves, infrared gas stoves, and burner heads of gas water heaters.
The electrode needle structure for generating high voltage arc on the market is mostly coated with a ceramic layer on the outer side of the electrode needle, wherein the ceramic layer is used for insulating the electrode needle and has certain high temperature resistance. For example, in the use process of a traditional burner, an electrode needle for generating a high-voltage arc is arranged in the air, the length of a commonly used needle is short, and when the needle needs to be particularly long, ceramics are generally added at the two ends of the needle, and no ceramics are added in the middle of the needle; under the condition of adopting premixed combustion, the electrode needle is required to pass through the combustion head, mixed gas exists in the combustion head, if the conventional method is adopted, the electrode needle can be contacted with the mixed gas under the condition that ceramic is not added in the middle, and serious safety risk exists in the combustion head that the mixed gas is ignited by discharging. For this reason, in the premixed combustion, the whole ceramic is coated outside the electrode needle, and the following disadvantages exist in the setting condition: 1. the cost of the long ceramic needle is relatively high; 2. the internal space of the combustion head is limited, in order to ensure that the whole diameter of the electrode needle is thinner, the wall of the ceramic needle is required to be kept thin, if the ceramic needle is made to be quite long, the ceramic needle is easy to break due to external impact, or the ceramic wall is likely to break in the process of installation or equipment transportation, once the ceramic needle breaks, the needle can discharge through a breaking crack and a metal sleeve, and the electrode needle cannot discharge at the tip after short circuit occurs; 3. when the needle is made longer, the voltage drop will be greater due to the greater resistance of the needle, the voltage between the two tips of the discharge will be much smaller than the voltage difference actually applied, and after the voltage difference is reduced, the intensity of the arc discharge will drop significantly, affecting the formation of the spark.
