Gasification furnace with buckling structure

Abstract

The invention discloses a gasification furnace with a buckling structure, belongs to the technical field of lighters, and aims to overcome the shortcoming that an injector head and an air mixing pipe which are in close fit are easy to loosen. The gasification furnace comprises the injector head and the air mixing pipe, and is characterized in that the lower end part of the injector head is inserted into the upper end part of the air mixing pipe, and is buckled with the upper end part of the air mixing pipe through the flaring edge of the lower end part of the injector head and the inner flange edge of the air mixing pipe; the air mixing pipe comprises a lower section; an inwards protruding part forming an upper through hole is arranged on the upper end surface of the lower section; a spacer pad with a middle hole is arranged below the inwards protruding part; and the diameter of the middle hole is smaller than that of the upper through hole. Buckling connection between the injector head and the air mixing pipe replaces original plugging, so that even if the injector head is cast by a zinc alloy, reliable and stable connection between the injector head and the air mixing pipe still can be guaranteed; the shortcomings of looseness and separation which are caused by high-temperature scorching heat are overcome; and meanwhile, the advantages of reducing the cost and improving the production efficiency are maintained.

Description

technical field [0001] The invention belongs to the technical field of lighters, and relates to a gasification furnace with a snap-fit ​​structure used for a windproof lighter. Background technique [0002] A gasification furnace assembled from a heat-insulating cup, spray head, and air mixing tube must be installed in a windproof lighter. The heat-insulating cup is fired from ceramics, and the spray head and air mixing tube are made of metal. The air mixing tube It is a hollow tube with an integral structure divided into an upper section and a lower section by a partition wall. In an existing gasification furnace, the injector head is made of copper, while the air mixing tube is made of zinc alloy, and the injector head is inserted into the air mixing tube tightly. Because the strength and rigidity of copper are less affected by temperature, under the working conditions, the tight fitting structure of the spray head made of copper and the air mixing tube cast by zinc alloy...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the present invention proposes a gasifier with a snap-fit ​​structure, the purpose of which is to overcome the defect that the injection head and the air mixing tube are easily loosened and separated due to high-temperature scorching when the tight-fit connection is adopted, so as to ensure that the two are at high temperature. Remains reliably connected for repeated use
