An improved burner

Abstract

The invention provides an improved combustor, and belongs to the technical field of gas devices. The problem that an existing combustor is poor in combustion effect is solved. The improved combustor comprises an outer burner, an inner burner, a pipeline assembly and an ignition column. The outer burner is buckled with an outer fire cover, an outer mixing cavity is formed by the outer fire cover and the outer burner in a defining manner, a plurality of main channels communicating with the outer mixing cavity are arranged at the bottom of the outer burner, and the cross sections of the main channels are in a ring shape. The inner burner is buckled with an inner fire cover, an inner mixing cavity is formed by the inner fire cover and the inner burner in a defining manner, a secondary channel communicating with the inner mixing cavity is arranged at the bottom of the inner burner, a through hole is further formed in the middle portion of the inner burner in a penetrating manner, and the through hole extends upwards and penetrates the inner fire cover. The pipeline assembly is provided with a secondary air inlet pipe corresponding to the secondary channel and a plurality of main air inlet pipes corresponding to the main channels in a one-to-one manner. The ignition column communicates with the pipeline assembly, vertically and upwards extends and abuts against the outer circumferential side wall of the inner burner. The outer burner and the inner burner are made of magnesium alloys. The improved combustor has the beneficial effect of being good in combustion effect.

Description

technical field [0001] The invention belongs to the technical field of gas appliances, and relates to an improved burner, in particular to an improved burner used in a gas stove. Background technique [0002] Gas stoves refer to kitchen utensils that are heated directly by gaseous fuels such as liquefied petroleum gas, artificial gas, and natural gas. The gas stove is mainly composed of a burner, an ignition device, a hob, an air intake pipe, a valve body and other devices. [0003] The burner includes a burner head, inner and outer fire cover and other structures. When working, the gas enters the stove from the intake pipe, enters the burner head through the adjustment of the gas valve, and mixes part of the air at the same time (this part of the air is called primary air). The gas is ejected from the fire hole of the fire distribution cover and is ignited by the ignition device to form a flame (the air required for combustion is called secondary air), which is then used t...

AI Technical Summary

Problems solved by technology

[0004] The interior of the burner is often provided with a flow channel of a specific structure. After the gas circulates in the burner, it is ignited by the ignition device. The internal circulation of the burner is not smooth, which easily leads to insufficient combustion of gas, poor combustion effect and low safety

[0005] However, the material of the gas stove in the prior art is general alloy steel, aluminum alloy or copper alloy, which not only has average strength, but also has poor temperature resistance and corrosion resistance, which affects the service life of the gas stove.
