Problems solved by technology

[0003] Although the improved structure has achieved good technical results, there are still deficiencies: first, the flame stabilization effect has not reached the best state, and can be further improved; second, the overflow is easy to enter the main flame hole or the flame stabilization hole to block the main flame channel or flame-holding channel; finally, the main fire channel or flame-holding channel is not easy to clean when it is clogged

Embodiment 1

[0028] like Figure 1-8 As shown, it is the best implementation mode of this embodiment. The burner fire cover in this embodiment includes a fire cover body 1 and a cover body 2 covering it. The fire cover body 1 can be in the form of a cylinder with an opening downward. , and can also be ring-shaped. In this embodiment, the ring-shaped fire cover is described as an example. The ring-shaped fire cover can be an outer ring fire cover or an inner ring fire cover. In this embodiment, the outer ring fire cover is mainly described in detail.

[0029] Wherein, the upper surface of the annular peripheral wall 10 of the fire cover body 1 is formed with radial main fire grooves 11 at intervals along the circumferential direction, and the cover body 2 is annular, and the annular top surface 21 of the cover body 2 is connected with the An inner ring wall 22 and an outer ring wall 23 extending vertically or obliquely downward on the inner edge and the outer edge of the annular top surface...

Embodiment 2

[0035] The structure is basically similar to that of Embodiment 1, the only difference is that the cross-section of the stopper 4 is a rectangular structure, the first sub-flame-stabilizing channel 312 and the second sub-flame-stabilizing channel 313 are arranged symmetrically along the stopper, and the cross-sectional area is from The wedge-shaped fire hole structure gradually increases from inside to outside.

Abstract

The invention relates to a burner fire cover. The burner cover comprises a fire cover body and a cover body covering the fire cover body, radial main fire grooves are formed in the annular circumferential wall of the fire cover body, partition blocks are formed in the adjacent main fire grooves, a flame stabilizing groove is formed in the upper surface of the partition block from inside to outside, and a flame stabilizing channel is formed by the flame stabilizing groove and the cover body. The burner fire cover is characterized in that the position near the outer end of the flame stabilizinggroove is provided with a separator, and the separator can divide the flame stabilizing channel into at least two relatively independent sub-flame stabilizing channels. Compared with the prior art, The burner cover has the advantages that each sub-flame stabilizing channel can play a role in throttling and shunting fuel gas in a flame stabilizing channel, the gas flowing speed of the stable fireworks can be effectively reduced, the flame can be stably burnt in the vicinity of the main fire channel, good flame stabilizing effect can be achieved, and the two ends of the sub-flame stabilizing channel can be used for pulling the main fire of the main fire channel, so that the fuel gas is uniform in combustion, it is not easy to leave the flame when burning, the flame stabilizing effect is further improved during combustion, and the split design of the fire cover body and the cover body is convenient to clean.

Description

technical field [0001] The invention relates to a fire cover on a gas cooker, in particular to a fire cover structure with a better flame stabilizing effect. Background technique [0002] In order to obtain better combustion efficiency, most of the existing cooker burners have a flame stabilizing function. For example, the utility model patent with the notification number CN2842216Y discloses "a kind of conical fire cover for a gas stove burner" and the utility model patent with the notification number CN202149492U discloses "a kind of burner fire cover". A kind of single flame hole combustion mode still exists the defective that flame jumps easily after combustion, combustion zone is unstable. A lot of outer fire cover structures with flame stabilizing functions are disclosed in the prior art, such as the Chinese utility model patent "A Kind of Outer Ring Fire Cover for Combustion Stoves" with the patent number ZL200920112857. There are flame stabilizing holes on the oute...
