Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Such as Figure 1-6 Shown, a kind of steady fire cover, tubular fire cover body 1, the inner cavity of this fire cover body 1 forms gas mixing chamber 10, and offers main fire hole 3 and steady flame hole 4 on its peripheral wall respectively, this main The flame hole 3 and the flame stabilizing hole 4 communicate with the gas mixing chamber 10 respectively. In this embodiment, the fire cover is an inner ring fire cover, and its top is sealed with a top cover 2 , and the top cover 2 and the inner cavity of the fire cover body 1 enclose the gas mixing chamber 10 .

[0023] One side of the above-mentioned top cover 2 extends outwards to form a protective eaves 21 integrally formed with the top cover 2, and an ignition hole 6 is provided on the side wall of the fire cover body 1 below the protection eaves 21, and the tunnel of the ignitio...

Abstract

The invention relates to a flame stabilizing fire cover. A cylindrical fire cover body is included; a gas mixing cavity is formed in an inner cavity of the fire cover body, and the peripheral wall ofthe gas mixing cavity is provided with main fire holes and flame stabilizing holes; the main fire holes and the flame stabilizing holes communicate with the gas mixing cavity; the flame stabilizing holes and the main fire holes are formed at intervals and the flame stabilizing holes are located below the main fire holes; and the bottom walls of the outer side ends of hole channels of the flame stabilizing holes are notched and suspended so that flame stabilizing open segments can be formed. Compared with the prior art, the flame stabilizing holes in the flame stabilizing fire cover can be usedfor heating the root portions of the main fire holes, a flame stabilizing effect can be achieved well, and the bottom walls of the outer side ends of the hole channels of the flame stabilizing holesare notched and suspended so that the flame stabilizing open segments can be formed; the flame stabilizing open segments are formed, the wall pasting effect of overflowing liquid can be interdicted, and therefore it is avoided that the overflowing liquid flows into the hole channels of the flame stabilizing holes, and it is thoroughly avoided that the overflowing liquid blocks the flame stabilizing holes; and the flame stabilizing open segments are arranged, flame stabilizing airflow in the hole channels of the flame stabilizing holes can perform pressure diffusing and speed decreasing in theflame stabilizing open segments, and therefore the flame stabilizing effect is improved.

Description

technical field [0001] The invention relates to the field of gas stoves, in particular to a flame-stabilizing cover. Background technique [0002] To ensure efficient and normal combustion of gas burners, it is generally necessary to stabilize the main fire. In the prior art, flame stabilization is generally carried out by interspersing small flame stabilization holes beside the main flame hole, such as: the Chinese invention patent with application number 201310196943.1 (publication number CN10418037A) discloses a burner, which includes an ejector mixer , outer fire injection nozzle, inner fire injection nozzle, air distribution chamber, outer burner head, and inner burner head, the outer burner head is set as inner and outer double cones, and the vertices of the inner and outer cones are located on the outer At the highest point of the horizontal position of the burner head ring, the outer burner head is provided with an equal number of strip-shaped outer ring main fire g...
