Description

Technical Field

[0001] The utility model relates to the technical field of gas stoves, in particular to a burner. Background Art

[0002] In existing stoves, the ignition distributor, induction needle and ignition needle are usually installed directly on the burner. When a fault occurs and needs to be replaced, it is usually necessary to remove the entire ignition distributor from the stove and reinstall the ignition needle, induction needle and ignition distributor. However, the insulating parts of the ignition needle and the induction needle are made of ceramic material. The dimensional tolerance of the ceramic body after molding is large, resulting in a large gap to be reserved during assembly to complete the assembly, causing the ignition needle to shake easily; after shaking, the ignition needle will be close to the fire cover or away from the fire cover. When the ignition needle is close to the fire cover, the discharge end of the ignition needle is close to the fire cover, resulting in a shorter discharge distance, a shorter corresponding arc length, and a lower ignition success rate. When the ignition needle is away from the fire cover, the discharge end of the ignition needle. In addition, the distance between the ignition needle and the ignition distributor will also directly affect the ignition effect. Therefore, a burner that can limit the ignition needle and the ignition distributor and facilitate installation and maintenance is required. Utility Model Content
