Burner fire cap for gas cooktop and burner using the same

A burner fire cap (1) for a gas cooktop includes a substantially annular cover body (2). A plane (3) is configured on the cover body. At least two bosses (4) protruding from the plane are distributed in a peripheral direction of the fire cap on the plane. Fire holes are disposed on the bosses. In the burner fire cap for a gas cooktop, at least two bosses are disposed and the fire holes are disposed on the bosses. As compared with a burner fire cap for a gas cooktop in the prior art, the distribution of the fire holes on the fire cap is changed, thereby enhancing the uniformity for heating a bottom of a utensil by using a burner having the fire cap.
