Causes of Leaking Tank Atomizers and How to Fix Them

 　　The so-called "leakage" of dripping atomizers generally refers to the condensation liquid flowing out from the air inlet, which can be wiped clean. Secondly, it may also be due to rough handling when refilling, leading to human error.

  　　Therefore, in this issue, we mainly discuss the leakage of tank atomizers and examine where the leakage points are located.   　　External Air Tightness   　　Checking the external air tightness of an atomizer is very simple. Block the air inlet with your finger and then suck hard from the mouthpiece. If it is difficult to draw air or only a little air can be sucked in, then the external air tightness of the atomizer is fine. During the inspection, to avoid poor contact between the mouthpiece and the top cap, which could lead to "false" air tightness issues, you can first remove the mouthpiece and directly press your lips against the air outlet to suck in.   　　If it is easy to draw in air, then check whether the oil chamber, base, and top cap fit tightly, especially whether the oil chamber is damaged. The appearance of the atomizer can also be easily observed for damage. Problems that can be solved by replacing parts are simple; if that doesn't work, you will have to replace the atomizer.   　　Internal Air Tightness   　　After checking the external air tightness, we cannot know the internal situation. This is like a straw; if both ends are blocked, you cannot suck air. However, if there is something like a "straw" inside, we cannot detect through external inspection whether the internal straw is airtight. At this point, we need to use another method: filling it with water.   　　The method is simple: completely block the oil outlet between the cotton and the oil chamber, then fill it with water and observe. If, when placed normally, you can see the liquid level continuously dropping and bubbles gurgling out of the oil chamber, then you can basically determine that there is a problem with the connection between the atomizer chamber, oil chamber, and base. The air pressure can escape through these gaps instead of through the cotton. This is not what we want to see, and this imbalance in air pressure will lead to leakage. Once this happens, generally, novice users will have to replace the atomizer; those with good manual skills can try to seal those gaps manually.   　　Cotton Tightness   　　The leakage situations caused by the air tightness of the above two types of atomizers are relatively rare. Generally, it is because players do not fully cover the oil outlet when making cotton. If the cotton does not cover the oil outlet completely, it cannot withstand the pressure of the oil, leading to slow leakage. The solution is to redo the cotton, ensuring that it blocks the oil outlet but does not completely seal it.   　　Incorrect Usage Method One   　　This situation is also something friends may encounter, usually occurring with players who like to take a few puffs without firing. To fully understand this issue, we need to know the principle of negative pressure oil guiding that is generally used in tank atomizers.   　　Here is a brief introduction to the steps of negative pressure oil guiding.   　　Step 1: When the atomizer is not being puffed, the atmospheric pressure in the atomizer chamber is the same as that in the oil chamber. Therefore, we only need the cotton to bear the slight weight of the e-liquid to help the atomizer not leak oil, which is quite simple.   　　Step 2: When we normally puff, the gas flow speed in the atomizer chamber increases, causing the pressure in the atomizer chamber to drop. At this time, the pressure in the oil chamber remains at standard atmospheric pressure, which is higher than the pressure in the atomizer chamber. Therefore, the pressure in the oil chamber will push the e-liquid out of the oil outlet into the cotton, where it evaporates.   　　Step 3: After we stop puffing, the pressure in the atomizer chamber returns to normal atmospheric pressure, while the air in the oil chamber does not increase due to the drop in liquid level, but the space increases, causing the atmospheric pressure in the oil chamber to drop. The normal atmospheric pressure in the atomizer chamber will then push the excess e-liquid and air around the "atomizer oil inlet" back into the oil chamber, which is why we can see bubbles emerging from the cotton holes in the oil chamber. This completes a simple and complete cycle of negative pressure oil guiding.     　　During the first step, if you start puffing without firing, causing the e-liquid to not be evaporated in time and accumulating in the cotton, eventually leading to the cotton being saturated with e-liquid that has not been evaporated, when it tries to flow back, the excess e-liquid cannot all return to the oil chamber, resulting in excessive accumulation. This can cause oil to spurt out when puffing, leading to a messy situation. In severe cases, when you puff hard, the cotton may be pushed out of the oil outlet due to air pressure, especially if the cotton is not packed tightly, and combined with the fact that the cotton shrinks after absorbing oil, this can ultimately lead to leakage.   　　So, don't just keep sucking on the atomizer without firing, continuously puffing...   　#p#分页标题#e#　Incorrect Usage Method Two   　　Blowing hard into the tank atomizer.   　　This still follows the basic principle of negative pressure oil guiding.   　　If you blow hard into the mouthpiece, causing the air inlet to be unable to withstand the crowded airflow, resulting in "suction resistance" corresponding to "blowing resistance," then the pressure in the atomizer chamber will definitely increase. If the increased pressure has nowhere to go, it will start to enter the oil chamber at normal atmospheric pressure. After a couple of blows, when you stop blowing, the pressure in the oil chamber becomes very high, and the pressure in the atomizer chamber returns to normal. The pressure in the oil chamber will then forcefully push the e-liquid out of the oil outlet, leading to leakage due to the pressure balance between the atomizer and oil chamber.   　　So light blowing is fine, as long as you don't feel resistance while blowing. Avoid blowing hard, as that will definitely cause leakage.   　　　Condensation Liquid Issues   　　Similar to bottom airflow dripping atomizers, bottom airflow tank atomizers can also experience issues with condensation liquid, causing the condensation liquid to mix with e-liquid and flow out from the air inlet, creating a false impression of leakage. In such cases, simply wipe it clean, and there's no need to worry. (Reply "condensation liquid" on the public account to learn about the causes of condensation liquid.)   　　The above are the main reasons for atomizer "leakage"; just check them one by one.   　　Leakage is not a big problem and can generally be solved by yourself.   　　We have discussed atomizer leakage many times; if needed, you can click on the two articles below to learn more:   　　Causes of E-cigarette Atomizer Leakage and How to Solve It?
