[0002] A burner is a device that allows fuel and air to be sprayed out and mixed and burned in a certain way. Its working principle is to convert substances into heat energy through the chemical reaction of combustion, that is, to mix air and fuel in an appropriate proportion through a premixing device to make them fully burned. Burners have a variety of classification methods according to their different properties. According to the fuel method, they are divided into oil burners, gas burners, light oil burners and dual-fuel burners.

[0015] Beneficial effects:

[0016] 1. The burner connection structure uses a fixing mechanism. First, the screw is rotated in the opposite direction to rotate the movable plate. The movable plate is limited by the limiting rod, so the movable plate can only move to the right with the rotation of the screw. The rightward movement of the movable plate will cause the L block and the fixed block to move to the right. Then, the positioning block on the left side of the connecting plate is slid into the positioning groove to position the gas nozzle to prevent the gas nozzle from being offset during installation. Then, the screw is rotated again to move the L block and the fixed block to the left, so that the fixed block enters the first fixing groove, the connecting plate is mechanically fixed, and the gas nozzle is further fixed. The installation is convenient and the operation is simple. It does not need to be fixed with multiple bolts, which can save time.

[0017] 2. The burner connection structure uses an auxiliary positioning mechanism. Before the positioning block enters the positioning groove, the guide rod is pulled to make one end of the L plate leave the second fixed groove. Then the positioning block is driven into the positioning groove, and the guide rod is released. One end of the L plate will drive into the second fixed groove through the elastic force of the spring to fix the positioning block, and further perform preliminary positioning of the gas nozzle to facilitate subsequent installation.
