The outer fire cover 1 is also provided with an ignition groove 14 and a groove air cavity 15, the ignition groove 14 is used to connect the side fire hole 121 and the outer main fire hole 131, and the groove air cavity 15 is used to connect the ignition groove 14 and the annular air cavity 10 of the outer fire cover 1. Because the outer fire cover 1 is a segmented structure, the plurality of segmented fire covers need to ignite each other, and when the flame is transmitted from the inside to the outside, if the layout of the fire holes from the inside to the outside is an obtuse angle, that is, when the angle between the inner plane 11 and the outer plane 13 is an obtuse angle, the flame transmission is acceptable. However, if the layout of the fire holes for transmitting from inside to outside is an acute angle due to the limitation of the appearance, that is, when the angle between the inner plane 11 and the outer plane 13 is an acute angle, the flame transmission will be poor or even unable to be transmitted. In the present embodiment, the ignition groove 14 is connected to the side fire hole 121 and the outer main fire hole 131, that is, it plays the role of transmitting the flame, so that the flame at the side fire hole 121 of a segmented fire cover can be transmitted to the ignition groove 14, and then transmitted to the outer main fire hole 131 of an adjacent segmented fire cover, so as to solve the above-mentioned problem. One end of the ignition groove 14 is connected to the side fire hole 121, and the other end of the ignition groove 14 is connected to the outer main fire hole 131.

The provision of multiple side fire holes 121 further shortens the length of the ignition groove 14, and the groove air cavity 15 can assist the combustible gas to be replenished to the ignition groove 14 in time, which makes the flame of the ignition groove 14 more stable, the better the fire transmission effect, and the less likely it is to accumulate oil stains in the ignition groove 14.

[0045] Preferably, the ignition groove 14 includes a first ignition groove and a second ignition groove that are connected, the first ignition groove is arranged on the side plane 12, the length of the first ignition groove is L1, the second ignition groove is arranged on the outer plane 13, the length of the second ignition groove is L2, L1+L2≤20mm. In specific implementation, the shorter the length of the ignition groove 14, the better the fire transfer effect.

[0046] In this embodiment, the side plane 12 and the outer plane 13 are arranged at an acute angle. Figure 4 As shown, the angle between the side plane 12 and the outer plane 13 is b, 0°<b<90°, when the ignition groove 14 is arranged on the outer fire cover 1 where the angle between the side plane 12 and the outer plane 13 is an acute angle, the ignition groove 14 can more obviously improve the fire transfer efficiency.

[0047] Furthermore, a plurality of segmented fire covers are arranged to form a basin-shaped cavity, the inner plane 11 is the inner side wall of the cavity, and the inner side wall and the inner bottom wall of the cavity are arranged at an angle a, 150°≤a≤170°. The basin-shaped cavity is equivalent to a heat collecting plate. When the outer fire cover 1 is arranged on the outer periphery of the central fire cover 2 and is spaced from the central fire cover 2, that is, the central fire cover 2 is located in the heat collecting plate, the flame of the central fire cover 2 can collect heat and reflect to the bottom of the pot, which is beneficial to improve the energy efficiency of the burner.

[0048] Preferably, if Figure 5As shown, the first projection of the inner wall of the cavity along the axial direction of the outer fire cover 1 is an annular structure, the inner radius of the first projection is r1, and the outer radius of the first projection is r2, then r=(r2-r1) / cosa≥20mm. That is, the inner plane 11 of the outer fire cover 1 is wider to ensure that the heat collection cavity has a better effect of collecting heat and reflecting it to the bottom of the pot when the central fire cover 2 burns.

[0049] Optionally, the fire cover structure further includes a central fire cover 2, and the outer fire cover 1 is arranged at intervals on the outer periphery of the central fire cover 2.
