Specifically, the method for processing the heating element in the electronic cigarette shall be further explained in accordance with the preferred embodiment of the invention, the processing method comprising procedures as follows:
Si, selecting alloy materials with high resistivity, including nicochrome, economet, aludirome and constantan alloy, most of which are standard wire stock in various shapes of filament or flake, for example, the alloy materials possibly being constantan alloy 6J40 or Cr2ONi80, etc;
S2, cutting the selected alloy materials, making the cut alloy material pieces has the length equal to the length of the heating element 100 before curled, as shown in Figure 5;
S3, dividing the cut alloy material pieces into the heating portion 110, the first connecting end 121 and the second connecting end 122, electroplating a plating layer 123 on the outer surfaces of the first connecting end 121 and the second connecting end 122.
S4, curling the electroplated alloy material, making the heating portion 110 in spiral shape, and making the first connecting end 121 and the second connecting end 122 correspondingly set on two ends of the spiral heating portion respectively, with the distance between the first connecting end 121 and the corresponding end of the spiral heating portion 110 equal to the distance between the second connecting end 122 and the corresponding end of the spiral heating portion 110.
S5, connecting the heating element 100 to a driving circuit of electronic cigarette via welding or some other way.
When implementing the processing method of the heating element in the present invention, the followed advantages can be obtained: the heating element 100 comprises a stable resistance value and a consistency in mass production;
the plating layer 123, first connecting end 121 and the second connecting end 122 are integrated designed, without any complex technique of welding or riveting. The plating layer 123 is formed via electroplating of fine metal or metal alloy of low resistivity, thus connecting portion 120 having extremely low a resistance value.
