Solution delivery idea

[Oliver]

My experiences of drip-smoking have led me to the belief that a device able to provide larger quantities of nicotine solution to the atomizer would produce a denser, more authentic experience.

Clearly there would have to be a radical re-design to enable this. Currently, the liquid is delivered via the wadding in the cartridge, and the flow into the atomizer is limited by the physics inherent in the design. Additionally, the liquid would have to be made weaker, given the larger quantities being delivered.

The solution might be to have the liquid delivered in measured doses via a mechanical system incorporated into the cartridge. The wadding would be done away with and a partially sealed area created in the cartridge for the liquid. Perhaps a miniature version of the valve found on shower gel bottles could be used, or maybe the viscosity of the liquid would mean that a small hole could be used without the fluid leaking.

Pressing the end of the cartridge would force a measured amount of solution through into the atomizer.

Just thoughts!.......

A lot of people are trying to find ways around the wadding in the cartridge or to make it last longer. On a different forum there are some very creative people.

One has tried "coarse steel wool" - which I just tried last night and I have to say it does work very well. I only had to refill one time today.

I had to use a language translator:

Another one has tried: a "piece of cut rope", unravelled and folded back into the holder, then cut to length - he says so far he has only had to fill it 1 time a day. (this one I will try tonight).

I will also give it a go!

The thing is, though, that you still wouldn't get the volume of liquid into the atomizer necessary to produce the density of vapor you get from putting a drop or two straight into the atomizer. Or would you?!

Thanks for the info

Let's hope lots of manufacturers and suppliers are reading these ideas. We need some brilliant new designs in case the liquid gets banned. In the "Mini" the cartridge is much closer to the atomiser but that only seems to achieve providing a mouthful of liquid nicotine

Well I tried the "cut rope" technique last night and found that I like the "steel wool" much much better. It could be that I just packed too much rope into the holder but it seems to me that I had better luck with the steel wool.

Has anyone else tried these yet? Let me know what you think.

You might be inhaling dangerous "heavy metals" using steel wool

 

[Atrack421]

Wow, some genius thoughts here fellas. But you might be harming your body with chemicals from the cut rope, or metal.

Just a thought, but keep the ideas coming.

I've been on that Dutch forum a lot and found the following replacements for the filling of the cartriges:

Fine mesh in surgical steel as used in aircondition filters. Do not use normal steel wool since this rusts and could provide a health risk

Cut rope made of natural fibre. Synthetic rope will burn and could be more dangerous than conventional cigarettes.

The white wool used in filters of fish thanks. Do not use cotton for the same reason as above.

I've been using the last one. One pak of wool will last you for years and it is easy to use. It does require a bit of experimenting on how much to use to fill the cartridge: to little and it leaks, to much and the cartridge delivers not enough fluid. Use just enough to hold the liquid in place even when turning the cartridge upside down. This give the most capacity for liquid, and maximises the flow to the atomiser. This is very comparable to the dripping method onto the atomizer(*). Injecting directly into the atomizer onto the coil however gives you the maximum smoke, taste and feeling.

(*) there is a lot difference between brands, types and even two atomizers from the same brand and type. My feeling is you have to be a bit lucky to get a good one, when buying.

This is fun. Kinda like finding the perfect cigarette filter. Maybe I could shave down an old Kent Micronite filter and stuff it in the cartridge! Reckon a charcoal model would be better? Nah, might get a barbecue taste with that one. My Savinelli pipes use balsa filters. My Brigham pipes use maple. Course, we have to deliver moisture, not absorb it. One can't substitute for the other. A better cartridge material? Let's keep thinking.

 

[Oliver]

Great stuff guys!

I'm gonna get some of that white wool stuff (is it called rockwool?) and give it a go.....

SJ

 

[LVD]

is it called rockwool?

Nope, rockwool, like glass fibre wool is used as insulation in buildings and inhaling the fibres in not healty at all. You have to use a dust mask when handeling, so not advisable to use for smoking. The white stuff is synthetic fibre wool. Opposite to rockwool fibres or glass fibres, you can bend and mould the synthetic fibre without breaking the fibres and thus avoid creating small particles that could be inhaled. Go to your pet shop and ask for synthetic filter wool for aquariums, that stuff does not give small particles, otherwise the fish would die.

 

[Oliver]

Right! Thanks for correcting me....

We are working on these and other solutions... it is however very difficult to come up with delivery system that will a. work fine and b. not overdose the user

The shampoo bottle idea for example could create not only problems of overdosage for you as a user but also kill the atomizer... however, I'm sure we'll come up with something. As for now we will produce HD cartridges that will double the life span of a cartridge (meaning you will be able to smoke it till the last drop of liquid and the flow will be much better too)

It is thanks to the community that we pick up these ideas for implementation, so please continue brainstorming because it can only come from within the community!

Ruyan: Sounds like you're designing a fifth of vodka that stops pouring after one shot -- to keep a person from getting drunk. The desire for more "smoke" is among the most frequently requested by e-smokers. More smoke! Better taste! If overdose is a problem (and I often overdose with my routine), then the answer might be to use lower densities of nicotine (I do 24mg all the time, for instance, and might function on half that if overdose from your improved devices proved a problem).

I don't think you're thinking of product liability with your caution on overdose. If not that, then let the user decide.

Users are probably killing more atomizers now with flavored liquids dripped onto hot coils than they would with this better design.

 

[Ludo]

As a manufacturer we have to follow government guidelines as well, not doing so will almost certainly result in a ban of e-cigarettes (at least, in europe). This kind of puts us in a limbo, but like I said, we are constantly working on new developments and I'm sure we'll come up with some kind of new cartridge or liquid delivery system.

@Smokey Joe: You want to ask for the white aquarium-filterwool at the petshop. They have other colours too; and while these work not too badly (especially the green one works almost as well as the white; it's a bit more coarse, but it does hold the liquid sufficiently) I do find it's difficult in use, because you can't see at all if your cartridge is getting empty (white ones get lighter in colour as more liquid gets used).

I use the 'straw-cartridge' most of the time now; this makes for a pure liquidstore in the bottom 1/2 to 2/3rd of the cartridge; then on top of it to seal off the cartridge I put the white aquariumwool.
I did have leakage once when I started out experimenting with this, and thought it had leaked at the side (wool not plugged in tightly enough). Later, I found that this was not the cause: that if you put in too much wool, the atomizer head pushing the wool against the top of the straw leaves so little room for the wool, that if that layer (wool) is too thick, you will compress the wool there so much that liquid just streams through... you need to have still some flexibility/room in the wool at the place where the atomizer presses against it. The straw though works in such a way, that it keeps the wool at the top, no wool being pushed too far into the cartridge to be reached by the atomizer-head anymore this way. While having pure liquid at the bottom half stops liquid from staying in the wool as residue there; no wool to stay in now, after all... (the top layer always gets smoked up better then the bottom part, if there is wool there that is).

To stop this kind of leakage I once had from being a possibility of happening, I slightly shortened the piece of (plastic drinking-)straw that is put into the bottom of the cartridge: now, I make that straw 1/2 to at most 2/3rd of the depth of the cartridge (instead of the 3/4 that I started out with); then I put wool on top of the straw (so filling up the top piece of the cartridge); then I take the syringe with liquid, push it through the wool, and fill up the cartridge bottom first (just keep filling until the top of the wool is reached).

Would be nice if some of you would try this method too... just me now I think, so not much to go from

 

[windblown]

Katink, I have been experimenting with your straw-cartridge today.....it was working really good until the wool cap fell into the atomizer. Oops! How do you keep the wool in the cartridge?

 

[katink]

Thanks Windblown for trying this; and I am real sorry the (wool) 'lid popped off' for you...
Of course I have to guess what might have caused this, seeing I haven't had this happen myself yet; but things I can think of:
- straw a bit too long (then the lid isn't thick enough to stick itself firmly sideways)
- not quite enough wool, so it couldn't get the sideways bit of force needed to set itself against the sides firmly enough;
- or perhaps you are used to doing what Jim advised for the normal cartidge (jerking it like a pen when the ink is needed in the front end) - great way for a cartridge filled all the way with wool, but not advisable to do with this contraption ?
- I don't know what device you were using, but we don't have Njoy over here; did you use that, and might the Njoy be differently built then the other brands of the classic model? If for instance the cartridge would not have the indentations along the side of the cartridge that mine have (which are same as e-cig cartridges) I would expect such a wool-lid to not behave the exact same for you as for me too...

Sorry I can't do more then this guessing; and I sure hope next time it will continue going strong until the cartridge is empty, rather then just the first part going well...
(I think 'not quite enough wool' would have the biggest chance of being the spoiler for you).

Hope you discover what it was...

 

[Oliver]

Ooops, Sorry Katink I missed your post there!

I will definitely give it a go as soon as I get some time to go to the pet store, thanks for the info. I shall probably try it in conjunction with Doc Jim's needle technique.

So busy, so busy!!

SJ

 

[windblown]

Katink, You were exactly right..... the straw was too long and the wool lid was too thin. Yes, I'm using an Njoy, but it does have the indentions in the cartridges like the ones you are using, so that part is fine. Now it is working very well with lots of smoke. Yeah! Thank you so much for all the helpful suggestions.
