Abstract

The present invention provides a large flame gas ignition device, including a base body connected to the end of the gas pipe and in a tubular shape with a central through hole, with a plurality of gas expansion areas on the top section of the base body, and a plurality of gas expansion holes penetrating the tube wall of the base body in the gas expansion area, and the plurality of gas expansion holes are arranged along the length direction of the base body in the gas expansion area. Since the tube wall of the top section of the base body is not closed, the fuel gas is not only released outward from the top of the base body, but also diffuses outward from the gas expansion holes of the top section to mix with the air. After being ignited by the spark, an upward flame is formed from the gas expansion area, and the flame surrounds the gas expansion area to form a thick root of the flame or a fire core, and the fire core is not completely exposed outside the fire outlet, and has a certain windproof property. In addition, the structure of the ignition device greatly improves the amount of gas fuel released and the mixing degree and mixing speed of gas fuel and air, forming a thick root and a large flame with a stable flame.

Description

Large flame gas flame discharging device

Technical Field

The open flame lighter is characterized in that the gas is directly burnt in the air, the flame is small and easy to extinguish, the structure is simple, and the cost is low. The existing windproof flame lighter has the advantages of complex structure, high cost and difficulty in extinguishing flame by wind. A general consumer usually selects a wind-proof lighter as a first choice, but the wind-proof lighter on the market at present is difficult to ignite when being used for igniting relatively flame-retardant tobacco, such as cigar, so that a multi-flame wind-proof lighter is generated, which can generate multiple flames, but has higher cost and complex structure. The open flame lighter is easy to blow out, and a windproof sleeve is arranged around the upper part of the flame outlet on the shell for ensuring that the open flame lighter has certain windproof performance, so that firstly, the user is easy to be scalded by the windproof sleeve on the periphery of the flame, secondly, the cost is increased by the windproof sleeve, the attractiveness of the lighter is reduced, and meanwhile, the flame is easy to be further reduced by the windproof sleeve.
