PV fuel injector

[smokinsimon]

Well the title says it all. Is anybody working on it? It's a solid idea, like a fuel injector in the car sprays the mist of gas, a PV fuel injector would spray a fine mist to the atty. No more wicks, no more cart filler no more messing with dipping, dripping and stuff.
It's gotta happen eventually.

No more leaking and constant refilling too.

Simplest method is to use inkjet style technology (piezo) for the spray to heater coil.

Been saying this for ages.

Soon as I get a few clear days, will build it.

I'm right there with you both. Kinabaloo, I think your piezo idea is spot on, but I would think the coil could be changed from a spring-shape to a screen type that would allow more liquid to be vaporized. The only issue with a screen type element, would that it would most likely require more voltage to heat up. May also require a thicker wall so the heat would not burn ya. Too many of us have these great ideas. One of these days, we will see a truly well built device that will work flawlessly, and give us exactly what we want out of these things. I just wish I had a metal lathe and some other machinist's tools. So many ideas, so little time....

Need me to come take care of something to help clear your schedule. Excellent idea

I've been thinking of setting something up to use poly fill to wick out of a container of liquid through a thick tube, like an extended cart but holding 5ml of juice. Seems if the juice path is large and poly filled to the right density including the container then capillary action will always try to equalize and distribute the juice... Lots of possibilities.

I wondered if anyone had given thought to something like an insulin pump.

I don't know if a device that mists the vapor would work very well. Unless the mist had nowhere to go but into the mesh/atomizer, it would coat the surface of everything it came in contact with - and if you design the mist to go nowhere but into the mesh, what's the point of it being a mist in the first place?

Mist just doesn't seem like an efficient way to get the juice to the atomizer to me. There's nothing wrong with keeping the juice a liquid IMO.

But it is a mist now; inhalation pulls a mist of droplets from the metal mesh towards the coil. Some misses and ends up back on the mesh.

An alternative would be a direct juice feed, which I have shown is certainly possible.

We both know that direct feed works - I'm failing to see what advantages there are to pre-misting the juice in the first place. If the juice is misted it's going to have far less volume than a direct feed, which could lead to the atomizer not getting enough liquid and drying out.

And, if the juice is pre-misted, what's the point of the atomizer anymore?

 

[kinabaloo]

The point of the heater coil would be to create warm vapor from the cool mist.

Rather than rely on air suction to get the 'mist' (droplets), it would be controlled electrically, as is the atty, and the juice itself could be sealed.

In the meantime, I'm working on something a bit like what I did before, and you and Tinear have done, but with a twist or two.

 

[MoonMan]

Nevermind, I get it now. I wasn't thinking about it the right way.

we need juice in gas form, in those little Co2 carts like used on an air rifle! Now that would be cool, pressurized, with a "snappy" little valve built-in to the body of the pv to release a shot of "nic gas" into the chamber....

 

[muldrick]

I was just sitting here wondering how I can make this butane cannister work.
I use my (18 gauge) syringe and can actually put juice in this container AND pressure at the same time.
I put fluid in the bottle about a month ago and just found it in my desk. I used pliers to push the valve in and the bottle still had pressure in it from when I did this a month ago.

years ago, they made fire extinguisers with a regular air valve stem like on a tire/wheel and you just filled the canister with water then charged it with air .....we could do that...as long as the master canister pressure was greater and the smaller "tank" the mixture would flow to the " user tank" when you inverted the master canister and connected your smaller tank to the same valve you used to fill the master canister with...clear as mud? yeah...I can see it in mind....

[sattec]

how about a nic inhaler, spraying into a pv burn chamber...are they pressurized.

hell i would just be happy with a directional mister that put out a set amount of juice per push in a convientant way.
I dont mind dripping i just find its clumsy to do in things like cars.
I think this is the main disadvantage ...if we had an easy bottle that that had a pump type action that would say put out 2/10ths of a mililiter of juice in a directional mist right into the atomizer mesh per pump that would solve a lot of frustraition with a really easy simple solution.
Of course it would have to be ergonomic and would probably be best suited to atomizers that are encased in a shell such as a 801 or 901 it wouldnt really help with the exposed atomizer type e cigs

You've just described MooMan's mod.

Do you really think a mist gets pulled into the coil? Interesting...

I thought it was just wicking to the coil?

The air flow speed is increased by having only small holes into the ceramic pot where the coil resides. It pulls tiny droplets of juice off the mesh and these land on the coil. Some miss and land on the metal bridge, ready to go round the juice path again (so the bridge has two purposes in fact).

This works well enough, to a point. But because the juice flow is dependent on air flow, and sufficient air flow at that, it is possible for the coil to get unnecessarily hot either at the start or end or a puff (manual or auto).

Hence I'm looking into direct juice feed and temperature control.
