Heating wire component in electronic cigarette and welding method of heating wire component

Abstract

The invention relates to the technical field of electronic cigarettes, in particular to a heating wire component in an electronic cigarette and a welding method of the heating wire component. The to-be-welded heating wire component in the method comprises electric leads and a heating wire which is wound on an oil suction rope. The method includes the following steps: step 1, removing outer skin of a connecting end of each electric lead to enable a core wire inside the corresponding electric lead to be exposed outside; step 2, electrically connecting one working electrode in a laser spot welder with the electric leads; step 3, enabling the core wire on the connecting end of each electric lead and a connecting end of the heating wire to be connected and to oppositely collide on another working electrode of the laser spot welder simultaneously, and enabling the laser spot welder to output current to integrally weld the core wire on the connecting end of each electric lead and the connecting end of the heating wire. After adopting the above scheme for welding, a welding point is enabled to be small and firm after welding, and faulty welding and false welding are avoided; resistance change is small, the welding point is free of heat energy conversion due to electrification and cannot be corroded by tobacco tar, and pure mouthfeel of smoke taste during smoking can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to a heating wire assembly and a welding method in the electronic cigarette. Background technique [0002] In the prior art, the electronic cigarette heating element and the wire are welded by tin welding or copper capillary riveting. When tin is used as the solder for welding, tin will pollute the e-liquid and cause heavy metal pollution. This method does not Environmental protection is not hygienic, and the heating wire element is nickel-chromium alloy wire or iron-chromium-aluminum alloy wire. When the tube is riveted, since the thin copper tube is a relatively active metal material, this type of material is easily corroded by the e-liquid, causing the e-liquid to be polluted; in addition, due to the force of the riveting, the connection end of the heating wire is more mechanically crushed, resulting in heat Defective wire phenomenon will affect product quality.

[0002] In the prior art, the electronic cigarette heating element and the wire are welded by tin welding or copper capillary riveting. When tin is used as the solder for welding, tin will pollute the e-liquid and cause heavy metal pollution. This method does not Environmental protection is not hygienic, and the heating wire element is nickel-chromium alloy wire or iron-chromium-aluminum alloy wire. When the tube is riveted, since the thin copper tube is a relatively active metal material, this type of material is easily corroded by the e-liquid, causing the e-liquid to be polluted; in addition, due to the force of the riveting, the connection end of the heating wire is more mechanically crushed, resulting in heat Defective wire phenomenon, affecting product quality

It can be seen from the above that the existing heating element welding technology will make the smoke oil polluted, not environmentally friendly and hygienic, and affect the quality of the heating element, etc.
