Abstract

A fire cover of a household cooking utensil burner comprises a body, wherein the body consists of an inner ring wall plate, an outer ring wall plate and a top plate. The fire cover of a household cooking utensil burner is characterized in that the inner surface of the inner ring wall plate is conical, a plurality of projections screwing left or right relative to the generatrix of the inner surface are arranged on the inner surface, the projections extend to the axial lower end face of the inner ring wall plate, and two adjacent projections form a fire groove. The top plate is a turbinate-frustum-shaped ring, a ring-shaped projection is arranged on the top plate, the top surface of the ring-shaped projection is a turbinate-frustum-shaped surface and is provided with a plurality of corniform grooves, wherein round fire holes screwing left are arranged on walls of one corniform groove or round fire holes screwing right are arranged on walls of another corniform groove. Besides, at least two horizontal air inlet slots for supplying secondary air are uniformly distributed on the ring-shaped projection. By utilizing the structure, the fire cover can be supplied with secondary air from the horizontal air inlet slots so as to sufficiently combust gas and save gas.
