Gas furnace head

Abstract

The invention discloses a gas furnace head. The gas furnace head comprises a furnace base, a center gas supply cavity and an external gas supply cavity, wherein the center gas supply cavity and the external gas supply cavity are separated from each other on the furnace base. The center gas supply cavity communicates with a first gas inlet pipe, and the external gas supply cavity communicates with a second gas inlet pipe. A first installation base is arranged at the open end of the center gas supply cavity, and a copper ring and the first installation base are connected in a matched manner through a rotation stopping mechanism. The gas furnace head further comprises a disk-shaped flame stabilizing cover, round protrusions are arranged on the middle portion of the inner side of the flame stabilizing cover, the round protrusions are embedded into a cavity of the copper ring, and positioning is realized through lugs protruding inwards on the side wall of the cavity of the copper ring. First protrusions are arranged on the upper end face of the copper ring, a groove is formed between the adjacent first protrusions, second protrusions are arranged on the upper surfaces of the ends, close to the cavity of the copper ring, of the first protrusions, the inner side of the flame stabilizing cover is attached to the upper surface of the second protrusion, and a flame stabilizing groove is formed by a gap between the flame stabilizing cover and the outer side wall of the copper ring. Compared with a traditional gas furnace head, the gas furnace head has the beneficial effects that the structure is simple, the cost is saved, and the burning and flame stabilizing effects are good.

Description

technical field [0001] The invention relates to the field of gas stoves, in particular to a gas stove head. Background technique [0002] The connection between the copper ring and the air supply cavity on the burner needs to be stopped. The previous stop mechanism usually needs to be machined, such as tapping a threaded hole on the copper cover, and designing a hole on the gas mixing chamber corresponding to it, and then use A pin connects the two holes to prevent rotation. [0003] When the copper ring is matched with the flame-stabilizing cover, it is usually necessary to design 4 pillars on the furnace head, and the 4 pillars limit the outer diameter of the flame-stabilizing cover for the purpose of automatic centering. The disadvantage of this structure is that it is necessary to find a place for the 4 pillars The structure is not simple enough; or a discontinuous positioning ring is designed on the end face of the copper ring, and there is also a corresponding ring on...

AI Technical Summary

Problems solved by technology

Due to the design of the burner itself, the following two situations will occur when using liquefied petroleum gas: 1. When using open bottle gas, the flame has a phenomenon of flame separation; 2. When using bottom bottle gas, the flame has a yellow flame phenomenon and cannot burn full
