Description

Technical Field

[0001] The utility model belongs to the technical field of lighters, in particular to a lighter gas outlet structure. Background Art

[0002] The gas outlet mechanism of a lighter generally includes accessories such as an air mixing tube, a gas outlet part, an insulation cup, and a conductive structure. The tail of the gas outlet part is plugged into the air mixing tube, and the head of the gas outlet part extends into the insulation cup. The gas in the gas storage box assembly is mixed with air through the air mixing tube, and the mixed gas is sprayed into the insulation cup through the gas outlet part. When the conductive structure is energized, sparks are emitted into the insulation cup, igniting the mixed gas in the insulation cup to form a flame.

[0003] A conventional conductive structure is described in a lighter combustion head disclosed in application number CN201720976426.X, in which a conductive cup is mounted on the upper end of the porcelain cup, an outer section of the conductive cup is mounted on the outer wall of the porcelain cup, an inner section of the conductive cup extends into the inner cavity of the porcelain cup, and a distance between a lower end of the inner section and an upper end of the air outlet is within the ignition distance range.

[0004] The inner section of the conductive cup in the above technical solution can be a conductive rod, multiple conductive rods or a conductive surface, which can be set as needed. Since the size of the heat-insulating cup is small, if the inner section of the conductive cup is too large, it will hinder the diffusion of the mixed gas and affect the shape of the ignition flame. Therefore, the inner section of the conventional conductive cup adopts a conductive rod, and the conductive rod needs to extend from the top of the porcelain cup into the porcelain cup. In order to ensure the ignition rate, the length of the conductive rod is generally designed to be longer, but the slender conductive rod has the problem of insufficient strength. During the ignition process, the mixed gas flows from bottom to top and the flow rate is fast, which easily causes the conductive rod to bend and increases the distance between the conductive rod and the gas outlet, which ultimately affects the ignition rate. Utility Model Content
