Description

Technical Field

[0001] The utility model relates to the technical field of gas burners, in particular to an interchangeable assembly structure of gas burners. Background Art

[0002] A gas burner is a thermal energy device, which is mainly used to deliver fuel and air into the furnace at the required concentration, speed, turbulence and mixing method, so that the fuel can ignite and burn stably in the furnace. Its working principle is to spray the gas into the burner, mix it with the air, and then ignite and burn it through the ignition device. The high-temperature gas generated is heat exchanged through the heat exchanger and outputs heat energy. It is widely used in small and medium-sized oil or gas boilers, including household water heaters and gas stoves.

[0003] A Chinese patent with publication number CN220453664U discloses a combustion fire cover assembly structure of a gas burner, comprising an outer cover and an inner cover, the inner side of the outer cover is rotatably connected to the inner cover, the inner side of the outer cover is fixedly connected to a first spring telescopic rod, one side of the first spring telescopic rod is fixedly connected to a first conical block, the inner side of the inner cover is provided with a first conical groove, the outer side of the lower end of the inner cover is fixedly connected to a gear ring, the outer side of the gear ring is meshed with the outer side of the gear, the lower end of the gear is fixedly connected to a motor, and the inner side of the upper end of the inner cover is provided with a first upper air hole. In the utility model, by arranging the first conical block, the first hammer-shaped groove, the gear ring, the gear, the first upper air hole, the second upper air hole, the second spring telescopic rod and the second conical block, it is convenient to switch the fire shape during the process of processing the cookware with the combustion fire cover. During the switching process, it is prevented that the aperture of the device gradually becomes smaller to form a phenomenon of holding air, thereby improving the processing efficiency of the cookware.
