It may also be understood that any one flame stabilizing hole 2321 is located obliquely above the first air outlet hole 2311 closest to the flame stabilizing hole 2321, so that the first air outlet holes 2311 and the flame stabilizing holes 2321 are distributed in a crossing manner, and thus, air between the first flame cover 230 and the second flame cover 220 can directly flow to the flame stabilizing holes 2321 through a space between two adjacent first air outlet holes 2311, secondary air supply of the flame stabilizing flame is improved, and secondary air flowing into between two adjacent first air outlet holes 2311 is beneficial to secondary air supply of the main flame, so that the main flame and the flame stabilizing flame are combusted more fully, and the stabilizing effect of the flame stabilizing flame on the main flame is better, and the flame combustion stability is improved.

Alternatively, as shown in fig. 5, the aperture of the first air outlet 2311 is larger than the aperture of the flame stabilizing hole 2321. Because the flame stabilizing hole 2321 mainly plays a role in assisting the combustion of the first air outlet hole 2311, the combustion of the gas led out through the first air outlet hole 2311 can be more stable through the arrangement, and therefore the heating stability of the burner 1000 is improved.
