Embodiment 1

[0028] Such as Figure 1~6 As shown, a gas burner includes a base 1 and an outer ring fire cover 13 and an inner ring fire cover 14 arranged on the base 1 . Wherein the outer ring fire cover 13 comprises a ring-shaped first fire cover body 2, the first fire cover body 2 includes an annular top surface 201 and the inner edge and the outer edge of the annular top surface 201 are vertical or inclined downward. The extended inner ring wall 203 and the outer ring wall 202, the first air mixing chamber 24 is formed between the above-mentioned annular top surface 201, the inner ring wall 203 and the outer ring wall 202, and the above-mentioned outer ring wall 202 is arranged at intervals along the circumferential direction Main fire hole 25 is arranged.

[0029] Further, the outer ring fire cover body 2 includes a first part 20a and a second part 20b, the first part 20a and the second part 20b are arranged at intervals along the circumference of the outer ring fire cover body 2, whe...

Embodiment 2

[0038] Such as Image 6 with 8 As shown, the difference from Embodiment 1 is that the inner ring fire cover 14 in this embodiment adopts a different structure from Embodiment 1. Specifically, the structure of the inner ring fire cover 14 in this embodiment is the same as that of the outer ring fire cover 13 in the first embodiment. In this way, the number of the inner ring vents 102 matches the number of the above-mentioned gas mixing tubes 22, and the free ends of each gas mixing tubes 22 are respectively connected to the corresponding inner ring vents 102, so that the outer ring cavity 11 passes through each The outer ring ventilation port 101 communicates with each gas mixing pipe 22 , and the secondary air supplement port 23 on the inner ring fire cover 14 is opposite to the secondary air supplement port 23 on the outer ring fire cover 13 .

Abstract

The invention relates to a distributor of a gas burner. The distributor comprises a first distributor body, the first distributor body comprises an annular top surface, an inner ring wall and an outerring wall, wherein the inner ring wall and the outer ring wall are formed by extending the inner side edge and the outer side edge of the annular top surface downwards or obliquely downwards; a firstgas mixing cavity is formed between the annular top surface, the inner ring wall and the outer ring wall, and main fire holes are formed in the outer ring wall at intervals along the circumferentialdirection, at least three supporting blocks used for supporting the bottom surface of s pot body are arranged on the annular top surface at intervals along the circumferential direction, each supporting block extends upwards, auxiliary fire holes communicated with the first gas mixing cavity are arranged in the inner side surface of the supporting blocks, and secondary air supplying openings are formed between every two adjacent supporting blocks; the invention further relates to a gas burner using the distributor. The device has the advantages that the structure is simple, the other pot support does not need to be additionally arranged, and the auxiliary fire holes are formed, so that the center load of the burner can be increased without reducing the height of the supporting blocks, andin addition, secondary air can be supplemented from the upper part of the first distributor body through the secondary air supplying openings, so that the combustion efficiency is improved.

Description

technical field [0001] The invention relates to the field of gas stoves, in particular to a fire cover and a gas burner using the fire cover. Background technique [0002] The gas burner includes a base, a gas mixing chamber, an outer ring fire cover and an inner ring fire cover, wherein the gas mixing chamber is set above the base, and the outer ring fire cover and the inner ring fire cover are respectively set above the gas mixing chamber . Among them, the outer ring fire cover is generally ring-shaped, including an annular top wall, an inner ring wall and an outer ring wall extending vertically downward or obliquely downward from the inner and outer sides of the annular top wall, and the annular top wall 1. The inner ring wall and the outer ring wall are surrounded to form a gas mixing chamber, and the outer ring wall is provided with an outer ring fire hole. The inner ring fire cover generally includes a cylindrical base and a cover body covering the base, and the cove...
