Kicking It Up a Notch - Juice Pump for Podigy

[Antebellum]

Uh-oh. Competition. It seems that imeothanasis is working on an "auto-feeding system" for the GG. I just watched the video in this thread:

http://www.e-cigarette-forum.com/forum/gg/22801-gg-auto-feeding-system.html

Now everybody's going to want one. Prodigy owners are going to want one.

So we see how he's doing it on the GG. Pretty nice.

I imagine that what would be better is a pump that meters out, say, .1 ml or so directly onto the atomizer. It should be an external accessory, and it should work with a Prodigy and a stock 901 or 801 atty. Pull the cart out, insert the juice pump, slide it down once for prime, and vape away. When vapor wanes, pump it again.

It should slide over the cart shell.

Yes, it would look sort of like a Borg device, but having enough juice to match a set of batteries would be very nice.

What do you think, folks? Do we want this? http://www.e-cigarette-forum.com/forum/members/imeothanasis.html

 

[vaporize me]

Count me in. Sounds like a solution for dripping and driving.

Couldn't something be made to replace the filler casing in the cart? So you would have just the mouthpeice and then add a pump feature that would slide into the bottom of the mouthpeice and slightly into the atomizer when the mouthpeice is put into place.

That would not be visible at all from the outside and would allow pump action on the mouthpeice.

Most of us probrably are not using the filler or the filler casing on the Prodigys anyways.

Hey, Reign,

Cool! Put it all inside and then pump it once by pushing the mouthpiece in. Sort of reminds me of the Penguin in the original Batman and Robin TV show.

It wouldn't carry the half-dozen or so ml that I'd envisioned, but it would be a nice stealth approach, and I like the idea of "pumping up" my vape.

 

[Antebellum]

Actually, now that I think about it, Reign, either would work. The external/internal model could be styled to match the Prodigy and made to look like a part of it, similar to the way imeothanasis's idea works, except really a pump/injector, not just a weepage model.

An internal pump/injector could work with any standard 801 or 901 shell, and it would do away with carts entirely. I could imagine this having a wide appeal, especially if it could carry 2 or 3 ml.

However, the advantage of either design would still lie with the Prodigy because the device is sealed. You can't kill a Prodge by overfilling. (I hope!)

An 801 atomizer is really a wonderfully simple device. Take the cart and mouthpiece out, and it's just a thin metal cylinder with an atomizer at the bottom.

Yep, the pump and juice container for the pump might entend the mouthpeice from the top of the atomizer a quarter inch to a half inch to allow a good pump and that much space would also allow more juice to be held

Plus a little volume would be gained just by needing no filler.

Heck yeah, we want this!

Anybody out there know how to make a metering-pump device this small?

[Antebellum]

Thanks, DW! Actually, those are neat, but I'm hoping for something a little less obvious. Also, it should have some design bling - furtive technology, so to speak.

I saw Imeo's post on this, and am, well, undecided. Right now, it only holds ~15 drops or so, which just isn't much for it's size. It requires drilling a < 1mm hole in the atty tube, which is tough to do without a decent drill press. I'm unsure how the 'container' lines up with the single hole drilled.

Once installed, I like the simpleness of it..it's using airflow the meter the liquid, by drawing fresh liquid in as you inhale on the GG...therefore has little to fail or break down, which fits with Imeo's 'keep it simple and mechanical' theme.

However..what happens when you switch out attys? Different attys have different draws, with no way to adjust the liquid deliver...think of it like a venturi effect on a carburator, even they have adjustments for idle mixture, which is very similar in idea to this. Maybe there's just not enough variance in draw from atty to atty that it doesn't matter?

Increase the capacity to 3-5ml, and it becomes much nicer. Find a way it can be a 'self-mod' to existing attys, or better yet, does not require atty modification (although the only way I see on this is for it to fill the cart instead..?)...and we're rocking.

Hope i can post a link:
Amazon.com: OILER PRECISION NEEDLE STYLE Home Improvement
search Amazon if link doesn't work it's a "OILER PRECISION NEEDLE STYLE" and they have what look like the same priced from $4.77 to $20. I haven't had time to order and experiment yet BUT when I ever get my Podigy i won't have to work on LM chips and battery boosts on my sticks and will start drilling the Prodigy

tinear came up with an auto-drip system. He calls it the Fang.

I wish I could do CAD drawing, but what I'm imagining is something like a piston in a cylinder. The cylinder has a very small hole in the bottom of it, and the piston is held away from the bottom by a spring that limits the distance it can travel. The piston also has a one way valve on its surface. When the piston is depressed, fluid is dispensed through the hole in the cylinder into the barrel of the atomizer. The distance the piston can move determines the amount of juice injected.

When the pressure on the piston is released, it moves upward, opening the valve to the juice chamber side. This lets a small amount of juice transfer to the injection side, repriming it for another pump.

A second valve, probably built into the filler port, is on top of the cylinder. It allows air in to replace the dispensed juice.

So we have a enclosed cylinder with a piston inside it. The piston has a shaft protruding through the top of the cylinder on which we push. When pushed, the piston moves down, displacing juice and forcing it through the injection hole.

And all this fits inside the shell of an 801 atomizer. It may end up sticking out a 1/4 inch or so, but that's fine.

Pressing in on the mouthpiece, in effect, "cocks" the device. Another way to look at is like "pumping up some vapor."

The challenges are making it small enough and cheaply enough to be a cartridge replacement.

Hopefully, it wouldn't look like a growth on the Prodigy and atomizer. In fact, I'm guessing it would be half-again or twice as large as a standard cartridge.

This is definitely complicated stuff, but I believe that if Steve comes up with a slick way to incorporate this as an optional feature for the Prodigy, then it could be very profitable.

That's a lot like the idea my BF is working on for me-I told him our problem and what I thought would be cool and he's trying to design it. I think something in the
cart that hold 2-3ml that you press or turn to release a metered amt of juice would be nice and not make the Prodigy much bigger and would keep the r
design of the Prodigy intact.

Sorry double post (iPhone went bonkers)

 

[violetvoo]

If anyone thinks of any ideas for materials or parts for it-feel free to share them-any input/help would be appreciated!

Thank you for sharing some ideas, violetvoo!
