Specifically, a first limiting groove 213 is provided on the outer periphery of the first air inlet cylinder 212, the inner edge of the annular upper cover 211 is snapped into the first limiting groove 213, thereby facilitating the assembly of the inner ring fire cover 1 and the annular upper cover 211, and the annular upper cover 211 and the first air inlet cylinder 212 are formed separately, which also facilitates the processing of the upper cover assembly 21.

[0057] Of course, in other embodiments, the annular upper cover 211 and the first air inlet cylinder 212 may also be integrally formed; or the annular upper cover 211 and the first air inlet cylinder 212 may be fixed by welding. In this embodiment, the first limiting groove 213 is provided at the upper end of the first air inlet cylinder 212. In other embodiments, the first limiting groove 213 may also be provided near the middle of the first air inlet cylinder 212.

Specifically, because the inner edge of the first inner ring 2111 is used to connect with the first air inlet cylinder 212, the inner ring fire cover 1 is installed on the outer periphery of the first inner ring 2111, so that the first flange 214 is sleeved in the air inlet 11, thereby reducing interference. The mounting hole 12 on the inner ring fire cover 1 is opened in the part outside the air inlet 11, and the fastener passes through the mounting hole 12 to be fastened to the annular upper cover 211. And in order to improve the installation stability of the inner ring fire cover 1, the mounting hole 12 is provided in plurality, and the plurality of mounting holes 12 are arranged at intervals along the circumference of the air inlet 11.

[0060] With this assembly form, the assembly of the inner ring fire cover 1 and the upper cover assembly 21 is more flexible: the inner ring fire cover 1 and the upper cover assembly 21 can be assembled separately first, and then the inner ring fire cover 1 is assembled on the annular upper cover 211; the main body 14 can also be assembled on the annular upper cover 211, and then the inner ring fire cover 1 and the upper cover assembly 21 can be assembled separately; or, the inner ring fire cover 1 can be assembled first, and then the inner ring fire cover 1 can be assembled on the annular upper cover 211, and then the upper cover assembly 21 can be assembled; or, the upper cover assembly 21 can be assembled first, and then the inner ring fire cover 1 can be assembled on the annular upper cover 211, and then the inner ring fire cover 1 can be assembled.

[0061] Compared with the inner ring fire cover 1 being directly mounted on the annular upper cover 211, in another embodiment of the present utility model, please refer to Figures 1 to 5 The upper cover assembly 21 includes an annular upper cover 211 and a first air inlet cylinder 212. The first air inlet passage 24 is provided in the first air inlet cylinder 212. The first air inlet cylinder 212 is mounted on the inner edge of the annular upper cover 211.

[0063] Furthermore, the upper edge of the first limiting groove 213 is provided with a first flange 214, and the first flange 214 abuts against the side of the edge of the air inlet 11 away from the lower cover assembly 22 to press the inner ring fire cover 1 and the annular upper cover 211 to the first limiting groove 213. Specifically, the first flange 214 serves as the upper edge of the first limiting groove 213, so that the main body 14 and the annular upper cover 211 are fixed together by pressing the side of the edge of the air inlet 11 away from the lower cover assembly 22, that is, the first air inlet cylinder 212 is riveted to fix the annular upper cover 211 and the main body 14, so as to ensure the fixed connection of the three and facilitate the assembly of the three.

[0064] In this assembly form, the first air inlet cylinder 212, the annular upper cover 211 and the main body 14 must be fixed first, and then the inner ring fire cover 1 can be assembled.

[0080] In the embodiment of the present invention, the inner ring fire cover 1 and / or the gas distribution plate 2 are made of stainless steel. Because the material of the burner 100 is usually required to have the characteristics of high temperature resistance, corrosion resistance, and non-deformation, so as to adapt to the high temperature environment of the gas cooker during the cooking process. Therefore, the inner ring fire cover 1 and / or the gas distribution plate 2 are generally made of materials such as copper or cast iron, or ceramic materials, which leads to the high cost of the inner ring fire cover 1 and / or the gas distribution plate 2, and the thickness is often large. Therefore, in the embodiment of the present invention, the material of the inner ring fire cover 1 and / or the gas distribution plate 2 is stainless steel, so as to ensure the high temperature resistance and corrosion resistance of the inner ring fire cover 1 and / or the gas distribution plate 2. On the other hand, the cost of the stainless steel material is low, which helps to reduce the cost of the inner ring fire cover 1 and / or the gas distribution plate 2. On the other hand, the stainless steel material can make a thinner inner ring fire cover 1 and / or the gas distribution plate 2. Correspondingly, the outer ring fire cover 3 can also be made of stainless steel.
