a stove burner

Abstract

The invention relates to a cooker burner, which comprises a base body, which has a gas mixing part and an injection part which are connected and arranged horizontally; the gas mixing part is annular and has a gas mixing chamber inside; Fire holes connected with the gas mixing chamber are arranged on the surface along the circumferential direction; the injection part extends outward from the gas mixing part, and an injection cavity connected with the gas mixing chamber is provided through the injection part. The outer end of the part forms the injection inlet; the nozzle is arranged at the injection inlet of the injection 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 structure of the cooker burner is greatly simplified, and on the basis of ensuring a long injection distance, it can avoid the collision resistance caused by the change of the mixed gas movement direction, thereby improving the injection capability, and at the same time, it can realize sufficient supply of secondary air And will not be affected by nozzle ejection.

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.
