The inner ring wall of the outer fire cover cooperates with the inner ring groove wall plate of the outer ring gas groove, and the outer ring wall cooperates with the outer ring groove wall plate of the outer ring gas groove.

The special feature of the direct-injection stove burner is that the height of the top surface of the partition plate relative to the ground is lower than the height of the top surface of the inner ring groove wall plate of the outer ring gas groove relative to the ground.

The above-mentioned direct-injection fire stove burner is special in that: the axes of the first and second outer fire holes are perpendicular to the top plate of the outer fire cover.

The special feature of the direct injection fire stove burner is that the top plate of the outer fire cover is parallel to the horizontal plane.

The above-mentioned direct fire type cooker burner is special in that: the upper end of the inner ring wall plate of the outer ring gas groove has a flanging radially outward, and the top of the flanging is in contact with the outer fire cover. There is a gap between the top plates, and the lower end of the inner ring wall of the outer fire cover cooperates with the drop on the outer peripheral surface of the inner ring wall plate.

The utility model relates to a direct-injection fire stove burner. Due to the adoption of such a structure and the setting of the cylindrical partition, the outer ring gas tank is divided into the first outer ring gas tank and the second outer ring gas tank, and the flow is divided. (1) There is enough secondary air to match the flame hole gas combustion; (2) Better mixing of gas and primary air. Gas is saved and red fire is prevented.
