Abstract

A top-intake three-fire-ring stove burner comprises a burner head, a distributor, a center fire cap, an outer fire cap and axial secondary air holes on the distributor. The outer fire cap comprises an inner ring plate, an outer ring plate and an annular plate, the inner ring plate or the outer ring plate is provided with fire holes, the burner head comprises an inner injection pipe, an outer injection pipe, a central outlet pipe and an outer ring mixing cavity. The top-intake three-fire-ring stove burner is characterized in that the annular plate is in the shape of an inverted cone frustum and provided with two circles of left-handed or right-handed fire holes. Upwards spiral fire is formed by the fire holes during combustion, secondary air intake is increased since secondary air entering speed is increased by the aid of the second air inlet holes so that gas is combusted sufficiently in sufficient air, and further, fire distribution is uniform due to the two circles of fire holes on the outer fire cap.
