In this embodiment, the limiting bump 12 and the supporting pad 14 are four and are disposed opposite to each other vertically. In this embodiment, the support pad 14 is provided not only to enable the outer race 1 to better support the components thereon, but also to provide secondary air to the gas burner through the secondary air gap 15 described above when in use.
The inner ring 2 is provided with a second annular wall 21 which extends vertically, the lower side edge of the second annular wall 21 extends inwards along the circumferential direction to form an energy-collecting annular wall 22, a mounting hole 23 for embedding the burner of the gas stove is arranged in the center of the energy-collecting annular wall 22, and the energy-collecting annular wall 22 uniformly inclines downwards from the side of the mounting hole 23 to the side of the second annular wall 21 along the circumferential direction, so that the effects of promoting the combustion of the burner and containing the overflow can be achieved. Moreover, the first annular wall 11 and the second annular wall 21 are disposed inside and outside oppositely, and a energy collecting gap 5 is left between them, so that heat conduction between the first annular wall 11 and the second annular wall 21 can be reduced, and heat dissipation can be further reduced, so that the energy collecting effect of the energy collecting assembly is better, and in this embodiment, the width of the energy collecting gap 5 is greater than 5mm (in this embodiment, the width of the energy collecting gap 5 is 7 mm). In addition, the top edge of the second annular wall 21 extends radially and outwardly along the circumferential direction to form an annular edge 25, and the annular edge 25 is shielded above the energy collecting gap 5, so that the heat dissipation from the inner ring 2 to the energy collecting gap 5 can be reduced to a certain extent, and the heat transfer on the inner ring 2 can be further reduced.
