Preferably, a plurality of the sub fire holes are further provided at both sides of the ignition hole.

In this scheme, adopt above-mentioned structural style, avoid producing when inner ring fire lid or ignition needle offset, catching fire badly.

Preferably, interior ring fire lid still includes the portion of protecting the fire, the portion of protecting the fire is including protecting fire groove and protecting the fire hole, protect fire groove certainly the top surface undercut of annular side wall, protect the fire hole set up in protect the below of fire groove.

In this scheme, being provided with of guarantor's fire portion does benefit to outside air and gas intensive mixing, promotes combustion efficiency.

Preferably, the inner ring fire cover further comprises an upper cover, the upper cover is provided with a plurality of fire outlet holes, the upper cover is located on the upper portion of the inner ring fire cover, and a cavity is formed between the upper cover and the fire turning groove.

A cooking utensil comprises the inner ring fire cover.

In this scheme, the cooking utensils that contain above-mentioned inner ring fire lid have the ignition and catch fire and the advantage that the turnover performance is good.

The utility model discloses an actively advance the effect and lie in:

for the inner ring fire cover, the turning groove is arranged above the ignition hole, so that after the ignition hole is ignited, flame passes through the turning groove, and the upper cover is ignited by mixing fuel gas at the turning groove and outside air, thereby obviously improving the ignition and turning performance of the inner ring fire cover and greatly reducing the problem of poor ignition turning. In addition, because the inner ring fire cover probably has clockwise and anticlockwise skew when the location to the location of ignition needle also has far and near skew, through setting up vice fire hole, make when inner ring fire cover or ignition needle location skew, the ignition needle still can ignite vice fire hole, thereby avoids producing and catches fire badly. The scheme has the advantages of simple structure, low cost, convenient processing and convenient batch production and use. Correspondingly, the cooker comprising the inner ring fire cover has the advantages of good ignition and fire-turning performance.

Detailed Description

The present invention is further illustrated by the following examples, but is not intended to be limited thereby within the scope of the following examples.

In the present embodiment, an inner ring fire cover 10 is disclosed, as shown in fig. 1, the inner ring fire cover 10 includes an annular side wall 11 extending from top to bottom, a fire turning groove 12 is formed in the annular side wall 11, the fire turning groove 12 is recessed downward from the top surface of the annular side wall 11, a plurality of ignition holes 13 and auxiliary fire holes 14 are further formed in the annular side wall 11, the ignition holes 13 are disposed below the fire turning groove 12, and the auxiliary fire holes 14 are disposed on two sides of the fire turning groove 12.

In the present embodiment, the turning-over groove 12 is disposed above the ignition hole 13, so that after the ignition hole 13 is ignited, the flame ignites the upper cover 17 through the gas at the turning-over groove 12 and the external air, thereby significantly improving the ignition and turning-over performance of the inner ring ignition cover 10 and greatly reducing the problem of poor ignition and turning-over. In addition, because the inner ring fire cover 10 may have clockwise and anticlockwise offset when fixing a position, and the location of ignition needle also has far and near offset, through setting up vice fire hole 14 for when inner ring fire cover 10 or ignition needle location offset, the ignition needle still can ignite vice fire hole 14, thereby avoids producing and catches fire badly.
