Description

The utility model relates to a combustible gas burner head made of stainless steel. Its main feature is that: the upper cover made of stainless steel is provided with a fire hole extending from the center to the edge, so that the flame of the nozzle in the center of the burner head can be guided Lead to the flame nozzle around the burner.

In the early structure of combustible gas burners, due to technical limitations, material acquisition and processing costs, they were all manufactured by casting, and their materials were limited to cast iron, copper and other materials, but due to the industrial structure The method of artificially manufacturing sand molds for casting is no longer suitable for today's production conditions. At the same time, the weight of the combustible gas burner made by casting is too heavy, which causes considerable troubles in storage and handling. Of course, it is not suitable for use. Or, because the surface of the combustible burner of cast molding is extremely rough, thereby can cause inconvenience on cleaning, it obviously has the necessity of improvement.

In the more advanced structural design of combustible gas burner, it has broken through the existing casting molding method, and can use stainless steel plate as material, and produce it by stamping, which not only greatly improves the processing speed, but also adapts At the same time, its product quality is uniform, and its appearance is smooth and delicate, which can provide consumers with better choices. Moreover, the combustible gas burner made in this way is extremely light in weight, and it is relatively light in storage, transportation and sales. Existing structures are more relaxed and convenient.

However, judging from the structure of the existing stainless steel combustible burners, the base (comprising the combustible gas tube) of the combustible gas burners generally seen on the market is made of stainless steel, and the existing cast type is still used above it. The main reason is that if the nozzle is made of stainless steel plate stamping, the strength problem will be caused when the ignition groove is set on the outer ring nozzle, because the design of the existing combustible gas burner is to ignite it The device is installed on the side of the nozzle of the furnace core, and when the combustible gas furnace is turned on, the combustible gas is first supplied by the nozzle of the furnace core, and the nozzle of the furnace core is ignited by the ignition device, and then the ignition groove is opened on the nozzle of the outer ring of the combustible gas burner. Guide the flame of the burner nozzle to the outer ring nozzle around the combustible gas burner (of course, when the user cooks with a low fire, only the burner nozzle is ignited, and when changing to a large fire, it must also rely on the ignition groove to guide the flame), there is no problem in setting up a fire groove on the existing casting outer ring nozzle, because its thickness is quite thick, and it can have better strength, even if a fire groove is provided, it will not affect Overall strength; but for the outer ring nozzle made of stainless steel, it is impossible to set up a fire groove, because it is formed by stamping, so its thickness is extremely limited, if another fire groove is set on it, it will inevitably be Its strength is greatly attenuated, and it is easy to be heated and deformed during use. This is the main reason why there is no stainless steel outer ring nozzle structure so far.
