What are the common problems with electronic cigarette coils
Apr 25, 2024
Common issues with e-cigarette coils include burnt smell, rusting or corrosion of the coils, and dry burning. The burnt smell is usually caused by overheating of the coil or insufficient supply of e-cigarette liquid. The solution is to ensure sufficient infiltration of the cotton core and adjust the appropriate smoking frequency. Rust or corrosion of the coil can be prevented by regular cleaning and the use of better quality coils. Dry burning is due to heating the coil without sufficient smoke liquid. The preventive method is to regularly check the amount of smoke liquid and use temperature control mode to avoid overheating.
Basic knowledge of electronic cigarette coils
Types and characteristics of coils
Electronic cigarette coils are mainly divided into two categories: Kanthal coils and stainless steel coils. Kanthal coils are known for their high temperature resistance and stability, making them suitable for beginners to use. Stainless steel coils are favored by advanced users because they can be used in temperature control mode.
The resistance of Kanthal coils is relatively high, usually above 1.0 Ω, suitable for oral suction. Its heat resistance ensures that it will not easily burn out after long-term use, but it is not suitable for temperature control mode.
The stainless steel coil is compatible with temperature control and power mode, with a wider resistance range, ranging from low resistance (0.2 Ω) to high resistance (1.5 Ω). This allows them to provide more steam and a richer taste, but the price is usually higher than Kanthal coils.
How to choose the correct electronic cigarette coil
When choosing e-cigarette coils, it is crucial to consider the usage habits and needs of e-cigarettes. For users who pursue high smoke, it is recommended to choose stainless steel coils with low resistance values, as they can work at higher power and generate more steam. For users who enjoy oral suction and pursue taste, the high resistance and stability of Kanthal coils are a better choice.
Understanding and application of coil resistance value
The resistance value of the coil directly affects the steam volume and taste of the electronic cigarette. Low resistance coils (below 1.0 Ω) allow for faster current flow and generate greater heat, resulting in a greater amount of steam. But this also means higher battery consumption and higher usage of e-cigarette liquid. In contrast, high resistance coils (above 1.0 Ω) generate less heat and relatively less steam, but have stronger battery life and slower consumption of e-cigarette liquid.
Taking an electronic cigarette using stainless steel coils as an example, if the coil resistance is 0.3 Ω and operates at a power of 50W, it can produce a large amount of smoke and a rich taste. By contrast, a device using Kanthal coils with a resistance of 1.2 Ω may only produce less smoke at the same power, making it suitable for users who pursue a delicate taste.
Common problems and solutions of electronic cigarette coils
The reasons and countermeasures for the burnt smell of coils
The burnt smell is usually caused by the coil overheating and the electronic cigarette liquid not being replenished in a timely manner. This may be because the suction port is too frequent, the electronic cigarette liquid absorption is insufficient, or the power setting is too high.
Countermeasure: Firstly, ensure that sufficient time is given between each suction to allow the cotton core to fully suck the e-cigarette liquid. For the first time using a new coil, it should be ensured to fully immerse the cotton core and start using it at low power, gradually increasing to the ideal smoking experience. If the problem persists, consider reducing the usage power or replacing the coil.
Prevention and treatment of coil rust or corrosion
Rust or corrosion of the coil may be caused by poor storage conditions or improper use. Moisture is one of the main causes of rust on metal components.
Preventive measures include storing e-cigarettes in a dry environment and regularly cleaning the coils and other metal components of the e-cigarette. Using high-quality coils, such as stainless steel coils, can also reduce the risk of rusting.
Solution: Once the coil rusts, it is recommended to replace it immediately. The use of rusted or corroded coils can affect taste and may pose potential health risks.
Identification and prevention of dry burning of coils
Dry burning refers to heating the coil without sufficient e-cigarette liquid, causing the cotton core to burn. Dry burning not only produces unpleasant odors, but may also temporarily or permanently damage the coils.
Identify dry burning: The most obvious signs are the pungent burning smell and reduced steam volume produced during suction.
Preventive measures: Regularly check the amount of electronic cigarette liquid to ensure that the cotton core is always saturated. Using temperature control mode (if available) can effectively prevent dry burning caused by excessive power. Adjusting the power appropriately to avoid exceeding the recommended power range of the coil is also an effective method to prevent dry burning.
Maintenance and replacement of coils
How to properly clean the electronic cigarette coil
Cleaning the electronic cigarette coil is a key step in extending its lifespan and maintaining a good taste. For reusable coils, it is recommended to clean every 2-3 bottles of e-cigarette liquid after replacement. The correct cleaning method includes removing the coil, rinsing with warm water, and then gently wiping the cotton core and coil with high alcohol. Finally, let the coil air dry naturally or gently dry with a hair dryer.
It is important to ensure that the coil is completely dry before reinstalling it into the e-cigarette for use. This can not only remove residual fumes, but also reduce the risk of short circuits caused by residual moisture.
Criteria for judging the lifespan of coils
The criteria for determining whether a coil needs to be replaced mainly include changes in smoke odor, reduced steam volume, and physical damage discovered through visual inspection. Usually, the average lifespan of a coil is between 2 weeks and 1 month, depending on the frequency of use and the type of electronic cigarette liquid. Sweet tobacco oil can shorten the lifespan of the coil, as high sugar content can form caramelized compounds on the coil, affecting its performance.
When the smell at the suction port is no longer pure or the smoke volume is significantly reduced, the coil should be replaced. Regular visual inspection of the coil is also important to check for burnt cotton cores or metal fatigue.
Step by step explanation: Replace the e-cigarette coil yourself
Replacing the e-cigarette coil is a simple process, but correct operation can ensure optimal performance and safe use of the e-cigarette.
Turn off the e-cigarette and separate the atomizer from the battery pack.
Unscrew the bottom of the atomizer and remove the old coil.
Clean the residual e-cigarette liquid inside the atomizer with a tissue.
Apply a small amount of e-liquid to the threads of the new coil to help the cotton core better absorb the e-liquid.
Install the new coil into the atomizer and tighten it again.
Reinstall the atomizer and fill it with e-liquid, wait for 5-10 minutes for the cotton wick to fully absorb the e-liquid.
Start using the new coil at a lower power and gradually increase it to the desired smoking experience.
By following these steps, users can ensure the best smoking experience after each coil replacement.
