Air lock issue, please help

[Eden Freeman]

I have a CROWN 3, I really like how it looks, but I have to unscrew the cap and lots of air bubbles come out of the coil, after that I can use it for a few puffs and have to do it again to release the vapor lock to get the air bubbles from the coil. What's wrong with it? Is there a way to fix it?
Please help, thanks.

I don't own a Crown but it sounds as though the juice isn't flowing to the coil properly. Your Crown 3 has pre-built coils right ?. If i were having the problem you're having i'd take out the coil unit and use a pin to adjust the wick where the juice would flow through. To put it bluntly "poke around in the holes in the base of the unit to open them up a little". I'm guessing the wicking material is blocking the holes a little too much.

Sounds like you're experiencing a "dry coil". When you open up the cap, it creates a small vacuum pulling air into the tank through the coils to create an air bubble.. when you screw the cap back down, it is doing the opposite, but since the air is at the top of the tank, it pushes juice instead into the coil.

What evan said is true.... but I would take it one step further. I would take a pin, and put a small hole into the wick. This makes it easier for the juice to get to the coil. Don't poke too big of a hole, or it would flood the coil with too much juice. I would start with the smallest pin you have (think no bigger than a straight pin) and put one hole in each side on an older coil or test coil for testing. See how well it wicks... if you need another hole, then do it until you get one that wicks fast enough.

I'll try that. Thank you so much

Wow, I'm impressed. You explained it really clearly. Thank you very much!

Sorry, I don't know why I got confused again. Why it creates a small vacuum when I loose the top cap? I was thinking there was a vacuum before I loosing the top cap, and why there was no bubble coming out from the coil?

Air is exciting the tank, that's what causes the pressure change, allowing more e-liquid to enter the coil. I think that's how it works.

In any case, you've gotten good advice and I hope it helps. Welcome to ECF Congrats on switching to vaping and keep asking questions until you feel you have it working "right."

When you unscrew the cap, the threading doesn't let air come in very quickly. Kind of like a slow leak in your tire. So the air doesn't come in through the top until you've unscrewed it most of the way. You're right, you do have a vacuum. However, while unscrewing the top, the top is raising up and creating more vacuum. Since the air can't get in through the threads, it pulls up from the bottom instead, creating the bubbles you see coming from the coil. Then when you screw it back down, you are pushing the juice down into the coil.

another thing that you can do is to turn the tank upside down for a couple of seconds to equalize the pressure.

 

[evan le'garde]

I'll try that. Thank you so much

Let us know later if you solved the problem.

You're right. With the cap on and the air control closed off, a vacumm is created inside the tank when you take a puff. When you remove the cap, the vacumm is released as air rushes into the tank and the tank pressure equalizes with the room pressure.

I'm thinking that your issue may be that your air control ring is turned (off) so that you create too much vacumm in the tank; this could restrict the coil from taking in liquid. Try rotating it around so that your draw (puff) is more loose. This should allow the coil to take in liquid.

It is normal to see some air bubbles coming from the coil as the air pressure adjusts inside the coil/tank after taking a puff.

Tanks are a closed system with the only pressure exchange via the cotton around the coil. This has to be to avoid leaking. The cotton is most likely your problem location. As per above poking holes in the cotton or doing something to decrease the density of the cotton will relieve the constriction. Obviously decreasing the density too much will cause leaking. Those are mass produced coils and probably not produced to close tolerances per cotton density. Another coil may work better, maybe not. Hard to say. Kinda like luck of the draw. Some tanks with small clearances between the vapor chambers and the outer glass will also suffer from problems with thick juices regarding pressure exchange between air and liquid.

I get air lock on the Melo III. It's a sure-fire bet.
The problem was never solved so I try not to use it.
I suspect the airflow was never as open as other tanks I use those coils in.
Unfortunately, vaping hardware is not a perfect science as people's preferences vary so greatly. Often we just say "it's not a good product" but the people who designed it did their best but it just doesn't work in every combination.

its like holding your finger on the end of a syringe and pulling the plunger out, it creates a small vacuum before the plunger is totally removed ( seal opens up) and when you replace the cap it seals first and then the cap continues to compress the air in it as it closes down ( like placing your finger on the end of the syringe and replaceing the plunger)

 

[Bunnykiller]

have you tried a new coil yet??? maybe the one you have has been wicked too tightly...
