Description

External fire cover of kitchen range burner Technical Field The utility model relates to the technical field of kitchen appliances, in particular to an outer fire cover of a kitchen burner. Background The traditional burner sold in the market at present consists of a central fire and an outer ring fire, in the use process, the central fire is needed sometimes, the outer ring fire is needed sometimes, and in the use process, the outer ring fire is needed to be transmitted through the central fire. In order to be able to transfer the flame, it is generally used to provide a flame transfer groove in the outer ring flame cover, through which the flame is transferred to the outer ring. In the prior art, the outer ring fire cover provided with the fire transfer groove is in the use, and the velocity of flow of the mixed gas of gas and air that flows out from the fire transfer groove is too big, causes the flame to take place easily when burning to leave the flame or take off the fire, has the problem that can not stable burning and fire transfer difficulty. Therefore, there is a need for an improvement to the outer fire cover of existing cooktop burners to address the above-described problems. Disclosure of utility model Aiming at the problems in the prior art, the utility model provides an external fire cover of a kitchen range burner, which can effectively prevent flame from being lifted or from being released and stabilize fire transmission. In order to solve the technical problems, the technical scheme of the utility model is as follows: The outer ring fire cover of the kitchen range burner comprises a cover body, wherein the top of the cover body is provided with a flange, the flange is provided with a through hole, and the through hole and the flange are obliquely arranged in the horizontal direction; a fire transmission groove is arranged above the through hole, and penetrates through the through hole and is communicated with the through hole; fire transmission holes are respectively formed in two sides of the fire transmission groove, and an included angle is formed between the axis of each fire transmission hole and the axis of each through hole; A gas hole is communicated below the fire transfer hole; and a plurality of adjusting holes penetrating through the through holes are formed below the fire transmission grooves, and the axial direction of the adjusting holes is not perpendicular to the axial direction of the through holes. Preferably, the inclination angle of the through hole and the horizontal direction of the flange is 1-10 degrees. Preferably, the included angle between the axis of the fire transfer hole and the axis of the through hole is 25-35 degrees.
