After the kitchen range table 500 is attached, the outer ring fire upper air inlet 4 and the inner ring fire upper air inlet 12 upwards exceed the kitchen range table at a proper height, so that the kitchen range table 500 can be positioned on one hand, and on the other hand, the phenomenon that a large amount of primary air enters a gas collecting cavity due to overhigh extension can be avoided.

And the primary air of the outer ring fire enters the outer ring fire gas collecting cavity 2 from the outer ring fire air inlet 5, the outer ring fire upper air inlet 4 between the stove table 500 and the outer ring fire gas mixing ring 200 and is injected into the outer ring fire injection pipe 3.

And the primary air of the inner ring fire enters the inner ring fire gas collecting cavity 7 from the inner ring fire air inlet 14, the inner ring fire upper air inlet 12 between the stove table 500 and the outer ring fire mixing ring 200 and is injected to the inner ring fire injection pipe 10.

Example three:

referring to fig. 1 to 5, when the burner is used in a gas range, the gas range includes the burner 100, the burner 600, and a cooktop 500. The stove table 500 is attached to the base plate 1 of the stove head 100 so that the base plate 1 is attached to the bottom of the stove table 500, and primary air enters between the stove table 500 and the outer fire mixing ring 200.

The foregoing is illustrative of the best mode of embodiments of the utility model only and is not to be construed as limiting the claims. The utility model is not limited to the above embodiments, but its specific structure allows many variations, as long as the variations within the scope of the claims are within the scope of the utility model.
