How to deal with spitback in a vaping device

 　　Boss, the atomizer I bought is leaking oil badly, what should I do! Every puff leaves my mouth full of oil! It's really uncomfortable!

  　　Unfortunate customer service: Huh? No way, I've used your atomizer too. I didn't have this problem. Why don't you bring it to my store for a look?   　　This is almost the main issue that customer service at every vape shop faces daily! Let's understand what leaking oil in electronic cigarettes is.   　　First of all, over 90% of electronic cigarette atomizers on the market use cotton as the oil carrier, and the working principle is to heat the liquid oil on the cotton with a heating wire to vaporize it through physical changes.   　　During this heating process, for various reasons, the oil does not completely reach the vaporization standard. Or the vaporized particles are too large, or even small droplets are ejected due to overheating of the heating wire. This situation is referred to as "leaking oil."   　　The phenomenon of leaking oil can occur in both DIY atomizers and pre-made coil atomizers, as long as their working principle uses cotton as a carrier. It can happen in any of them.   　　We have summarized the following reasons for the occurrence of leaking oil:   　　1. Cotton has over-saturation (meaning the cotton is overly soaked with oil), which mostly occurs in pre-made coil atomizers and oil storage atomizers.   　　The principle is similar to putting a hot iron wire into water; the water in contact with the wire instantly heats up to steam, and the temperature difference between the water that hasn't touched the wire is too great, causing some small droplets to splash out.   　　2. In oil storage atomizers, if too little cotton is packed during the cotton leg process, it causes the oil to leak onto the cotton. The principle of leaking oil is similar to the first point. However, the reason is that the cotton leg is not well made and cannot properly seal the oil inlet.   　　Of course, if the cotton leg is too tight against the oil inlet, oil flow will be obstructed. Then your atomizer will get burnt.   　　3. For DIY enthusiasts, the mainstream heating wires are mostly fancy wires, such as Clapton, Tiger, and Alien, among others. Wrapping fancy wires is indeed a skill. It's not just about randomly wrapping a few wires together. Different materials and thicknesses of heating wires have significant differences in thermal capacity and heating speed. When two wires with vastly different properties are wrapped together, it leads to severe temperature differences in the oil on the different heating wires, causing significant leaking oil.   　　Another issue is that the heating wire material is correct, but the wrapping technique is poor, leading to large gaps between two or more wires, causing excessive condensation. The principle is like dripping a few drops of water into hot oil. You can imagine the result.   　　This is why you can find 10 pairs for 20 yuan on certain platforms, and I've even seen dual-core Clapton heating wires made of ni80 material for as low as 1.2 yuan per pair. Meanwhile, some ni80 fancy wires can cost dozens or even hundreds of yuan for a pair.   　　A side note:   　　Before wrapping fancy wires, you first need to calculate the thermal capacity of the heating wire, then select different shapes of heating wires with relatively close thermal capacities from many options. This ensures that uneven heating does not occur. Calculate the contact area between the heating wire and cotton, etc.   　　Wrapping heating wires requires relatively good skills. Currently, apart from one or two types of heating wires that can be machine-wrapped, most are hand-wrapped. Wrapping a good pair of heating wires takes over half an hour to complete. Due to the manual nature, the failure rate is relatively high.   　　So, I sincerely advise everyone! Those fancy wires that can be had for just a few yuan, especially the so-called ni80 material, how much heavy metal or other substances are you inhaling? Just think about it! Even worse, if you recommend them to your friends, please spare them!   　　4. The data on the device does not match the power requirements of the heating wire. When the output power on the device is too high, the heating wire heats up instantly, leading to leaking oil. When the output power is too low, the heating wire's temperature is insufficient to reach the oil vaporization standard, causing leaking oil!   　　I advise new friends that all heating wires and pre-made coils have their corresponding resistance. Depending on the resistance, they have a corresponding output power range. It's not that you can adjust to your preferred power with a regulated box. This is not possible!
