The mixed gas entering the gas mixing chamber of the outer ring fire cover 200 can flow out from the first outer ring fire holes 202 and be ignited to form a first outer ring flame.

Referring to fig. 5, in the embodiment of the present application, a plurality of grooves 203 may be disposed at intervals on the top of the outer ring fire cover 200, each groove 203 has a first sidewall 2031 and a second sidewall 2032 that are sequentially disposed along the circumferential direction of the outer ring fire cover 200, the top of the first sidewall 2031 and the top of the second sidewall 2032 are disposed opposite to each other, the top of the first sidewall 2031 and the top of the second sidewall 2032 are flush with the top of the outer ring fire cover 200, the bottom of the first sidewall 2031 and the bottom of the second sidewall 2032 are disposed to extend opposite to each other, and the bottom of the first sidewall 2031 and the bottom of the second sidewall 2032 are connected to each other.

Of course, the first outer ring fire holes 202 may be disposed on both the first side wall 2031 and the second side wall 2032, which is not limited herein.

In addition, the reason why the ignition portion 201 is provided at the groove is that: it is known that the outer flame temperature of the flame is the highest, the inner flame is the lowest, and the temperature of the flame core is the lowest, and the ignition portion 201 is disposed at the groove 203, so that the outer flame of the flame generated at the first outer ring flame holes 202 can act on the cooking utensil as much as possible, thereby improving the cooking efficiency.

With reference to fig. 3-5, in the embodiment of the present application, the outer sidewall of the outer ring fire cover 200 is provided with a plurality of second outer ring fire holes 204 at intervals along the circumferential direction of the outer ring fire cover 200, the outer sidewall of the inner ring fire cover 300 is provided with a plurality of inner ring fire holes 301 at intervals along the circumferential surface of the inner ring fire cover 300, and the plurality of second outer ring fire holes 204, the plurality of first outer ring fire holes 202, and the plurality of inner ring fire holes 301 may form three outer, middle, and inner combustion rings, so as to further improve the cooking efficiency.

In the prior art, since the back of the outer ring fire cover 200 is an inclined surface, when the first outer ring fire hole 202 is processed, it is required to process from the back of the outer ring fire cover 200. The most ideal processing method is to make the drill bit with the holes perpendicular to the inclined plane of the fire holes, but for the burner fire cover structure with a complex shape, there is no space for the drill bit to punch the holes, and the inclined holes can make the first outer ring fire holes 202 obliquely arranged, and the obliquely arranged first outer ring fire holes 202 interfere with flames generated by other wall surfaces in the combustion process to cause local combustion insufficiency, and the CO emission is increased. Therefore, under the condition that the central axis of the first outer ring fire hole 202 is vertically arranged, how to conveniently and efficiently process the first outer ring fire hole 202 is a technical problem which needs to be solved urgently.

The boss 205 of the embodiment of the present application may be integrally formed with the outer ring fire cover, and may be only disposed on the back of the corresponding ignition portion 202 of the outer ring fire cover 200, or the boss 205 may be disposed on the back of the outer ring fire cover 200 in a closed loop. However, the arrangement that the boss 205 is disposed in the back of the outer ring fire cover 200 in a closed loop can reduce the space of the gas mixing cavity of the outer ring fire cover and increase the manufacturing cost, so that the boss 205 is preferably disposed only at the back of the corresponding ignition portion 201 of the outer ring fire cover 200, so as to reduce the space occupation of the gas mixing cavity of the outer ring fire cover 200 as much as possible under the condition of conveniently processing the first outer ring fire hole 202.

It should be noted that, if the inner ring fire cover 300 is also provided with a fire hole structure similar to the first outer ring fire hole 202, the back of the inner ring fire cover 300 may also be provided with the above-mentioned boss 205, so as to facilitate the processing of the fire hole on the inner ring fire cover 300.
