1. Comparison and identification of gravure marks on the shell: There is a circular gravure mark on the upper and lower hinges of the genuine Zippo lighter. This gravure mark is difficult to be exactly the same on imitations and can be used as a basis for judgment. As shown in the picture, the genuine solder joints are large, shallow and irregular, while the fake solder joints are small, deep and regular.
2. Comparison and identification of hinges: The conventional model of genuine Zippo hinges has 5 hinges, three narrow and two thick. They generally protrude from the fuselage by about 1.5 mm, and the rollers are 0.5 mm away from both ends of the hinge. distance. Looking from the inside of the fuselage, there is a dotted line at the connection between the upper and lower hinges. When the box is closed, the upper and lower dotted lines will become a straight line. However, imitations are generally rough in workmanship and come in many patterns. There are three, four, and five hinges of various sizes. consistent.
3. Comparative identification of sparkling wheels: Zippo's sparkling wheels have applied for patents from design to materials. The texture on the sparkling wheel is that the upper layer is tilted from right to left, and the lower layer is tilted from left to right. Arranged in a rhombus shape with clear texture. Imitations generally have only one layer of texture or the texture is reversed and unclear. Some imitation lighters even use the same horizontal stripes as disposable lighters.

Notes:
1. Hold the lighter in your hand for at least 30 seconds. The reason is that after the lighter is transported and stored, the gas There is a certain difference between the room temperature and the ambient temperature. Hold it for a while to allow the liquid to vaporize to reduce the adverse effects of the temperature difference, so that ignition will be smoother.
2. Do not continue to ignite repeatedly. A lighter is not a toy. Ignition of a gas machine requires a process. Repeated ignition not only seriously affects the life of the machine, but also deforms the spring mechanism. The principle is just like bending a lighter repeatedly. Like wire.
3. Lighters are consumables, so pay attention to maintenance! Flint gas lighters need to clean the ignition port regularly. This is because the dust after flint friction will fall around the ignition port, and the ignition port of most gas machines They are all very fragile and can only be repaired once they become clogged.
