Stove burner

Abstract

The invention relates to a stove burner. The stove burner comprises a base body, a nozzle, and an ignition needle; the base body is provided with a gas mixing part and an ejector part, the gas mixingpart and the ejector part are connected and horizontally arranged, the gas mixing part is annular and is internally provided with a gas mixing chamber, and a fire hole communicating with the gas mixing chamber is formed in the inner ring surface and the outer ring surface of the gas mixing part in the circumferential direction; the ejection part extends outwards from the gas mixing part, an ejection cavity communicating with the gas mixing chamber is formed in the ejector part in a penetrating mode, the ejection cavity forms an ejector inlet at the outer end of the ejector part, the nozzle isarranged at the ejector inlet of the ejection part, the ignition needle is fixed on the base body, and the discharge end of the ignition needle is close to the fire hole. The stove burner structure isgreatly simplified, collision resistance due to the change of the direction of movement of the mixed gas can be avoided on the basis of ensuring the long ejection distance, the ejection capacity is improved, and meanwhile, the stove burner can achieve sufficient replenishment of secondary air and is not affected by the ejection of the nozzle.

Description

technical field [0001] The invention relates to the technical field of stoves, in particular to a gas burner. Background technique [0002] Existing stove burners are mainly divided into two types: upper air intake and lower air intake. [0003] Such as authorized announcement number is CN2771661Y (application number is 200520056580.2) Chinese utility model patent "a kind of upward wind energy-saving burner", wherein the burner disclosed is a kind of cooker burner of upward wind type. Due to the effective installation position and space of the stove burner with upward air intake, the length of the ejector tube is limited, which greatly affects its ejection ability and the mixing uniformity of the mixed gas. Under the cover, it is easy to cause the nozzle to be blocked, and secondly, the nozzle will be more seriously affected by heat. Of course, when this type of burner is used, it has certain advantages, that is, it is not easy to turn off the flame when opening and closin...

AI Technical Summary

Problems solved by technology

Bottom-inlet type cooker burners, because the air-mixing chamber is not only the channel for the mixed gas to move upward to the fire cover, but also the channel for the external secondary air to be supplied to the inner ring, so the area of ​​the waist-shaped hole for secondary air is always limited.
