Atomizer Question

[Winace]

If someone (preferably more than one) can give me the exact process of liquid transfer from the bridge to coil I would appreeciate it!

Every atomizer I have attempted to full disassemble has been destroyed in the process.

I am basically wanting to confirm/deny that the bridge fully encases the coil cup and actually pulls liquid from the bottom (underneath) of the coil cup and pulls is up a fiberglass wick via a venturi effect created when pulling air through the atomizer.

Thanks in advance for the discussion!

Does anything come up through the vent hole to the coil (underneath the coil)? Is there only one single strand of that fiberglass like wicking in contact with the coil? Does it actually contact the coil? If so, does it wrap around the coil? Thanks! A cross section picture would me cool (to see through the side of the bridge (between coil and bridge)). One more question, under the bridge is a metal bridge support. Is the wicking sandwiched in there? Or does it wrap that piece of metal?

[Houdini]

That whole clump of fibers is attached to the underside of the bridge and hangs down on top of the coil. It doesn't wrap around it, it just hangs on top of it and is in contact. I don't know how it's attached inside the bridge. I think it's just stuck in between the porous material and the metal bridge support thing.
Oh, and I think the 510 is the only atomizer that has that little brush looking wick hanging down like that.



Air comes up through the holes in the bottom of the pot.

Remember, only the 510 will have this supplemental wick.... so people with a 901, M702, M401, etc.. etc.. won't know what you're talking about! And remember that a 510 atty will work without the supplemental wick... just not the same or as well.

Anyway... on the 510, the supplemental wick is sandwiched between the metal mesh and the bridge support. They just use this as an anchoring mechanism. That wick then goes down and is kinda wrapped around the coil. At least it is trapped by the coil in the ceramic coil pot.

Liquid gets down to the coil via two mechanisms in the 510... from the supplemental wick (which has already been discussed), and via the traditional Ruyan mechanism.. In other words.. the liquid "wicks" down the sides of the mesh on the bridge and then runs along the sides of the coil pot. Air comes up through the coil pot via the hole in the bottom of the pot, and that creates a low pressure area in the coil pot... drawing the liquid into the pot via holes in the sides of the pot. This is the true "atomization" part of the atomizer (according to Ruyan). The atomized liquid hits the hot coil, or soaks into the "other" wick that runs through the center of the coil. Either way.... the liquid gets to the coil.

So you have liquid coming at the coil from three sides... and air coming up from underneath the coil. The liquid vaporizes and the air stream carries the vapor out of the coil pot, past and around the bridge, and then to your mouth via the air "ducts" in the mouthpiece. The vapor does NOT flow back through the cartridge filling.

Hope that helps!

As suspected. I cut away the bridge and metal support leaving just the pot, coil, and mesh around the pot. All mesh was below the surface level of the pot. I dry hit till there was no vapor whatsoever and then hit the mesh (on side of pot) with a very slight amount of fluid. I then got good vapor and flavor. This is due to the air being pulled through the intake under the coil carrying droplets and hitting the coil.

The fiberglass wick, from my testing conclusions, has one advatage, the rest are disadvantages. The advantage is to evacuate the coil of excess fluid. Air being pulled up through the coil would allow any accumulated fluid to wick UP the material and back to the bridge. Other than that, it will assist in flooding and contribute to fluid byproduct accumulation on the coil and this material itself.

If this wicking material is saturated and you pull air through the atomizer cavity, the direction of flow would gravitate upward. When air current stops it would reabsorb and potentiolly hit the coil directly. Depending on the tightness and uniformity of the coil winds it could pull in more fluid to flood itself.

If that wick was not present and the bridge was in full functional capacity (no compression or such) do you not believe this would be a more functional design? Do you think the possibility exists they over-engineered the design? Why not run a single strand or two from the bottom of the mesh up through the vent to the coil?

It's easy enough to remove the wick on a 510.. or you can buy the clones that don't have the wick from the get-go.

You will see that the vapor production goes down, liquid consumptions goes down, and they basically work like a "hot" 901.

I don't agree with you on the capabilities of the wick. I don't believe the wick ever pulls excess liquid away from the coil.. nor do I believe that the airflow causes liquid to backstream up the wick. The liquid will simply migrate from high concentrations to low concentrations due to the "wicking" properties of the material.
