Alternative cartridge design

[jigtg]

dx.sku.14562 cartridges hold very little liquid so I made a little modification. Original design has a little pod that sits inside the cartridge.
This piece of plastic is meant to replace the pod and is made of thin flexible "packaging plastic" that is bent to fit inside cartridge. I made a little curve to the tip with heated metal to allow better air flow. To hold liquid, I'm using normal tip filter cut in half and made little puffier. Works quite well and I have not found signs of plastic melting. Getting sufficient liquid flow to atomizer when cartridge is running out seems to be the only problem so far.

Cool- another innovator like myself- cool design jigtg. If it works alot better than the standard cartridges, perhaps you could market these mods It certainly looks like quite an innovative design idea, it could give new life to hte failed mini cigarrette concept, making it a much more attractive choice for htose that want mini eciggs, but are put off by the short cartridge life, hard draw, and plastic taste of mini cartridges. The Cigg filter tip idea is a great idea too

I wish I could see that 2nd picture a little better. Pretty hard to decipher inside there!

Either way, LOVE the idea! Keep up the good work!

Original cartridge actually has a similar passage for vapor. Under the pod, there is ~5mm of space that seems to serve no purpose so I don't think they even wanted to make a cartridge that holds much liquid.

Did another one but this time bended the plastic slips from atomizer vapor holes inside so they make a somewhat steady surface, thus resulting in better contact with atomizer when thick layer of filling is placed on top of it. Since it also regulates how much liquid gets through, I placed much less filling inside the liquid container. Down side being that liquid is more likely to leak out from the actual liquid container. Vapor thickness and stability was great for a good while after which something happened and it stopped working. I suspect top and down fillings might of lost contact or something.

It should look like this:

Vapor goes out from gaps on both sides.

If you get a good design figured out, keep me informaed and I'll try it with my crappy mini ecigg that tastes like a burnign straw and only lasts a couple of ciggs worth. I'ts just sitting around collecting dust because of htose two issues right now.

Did some calculations and this cart can hold only ~0.78ml if filling and vapor holes are left out altogether. According to https://........../shopping/shopcontent.asp?type=density that would mean only ~8 cigarettes. Original cart holded about 0.33ml(assuming no filling) as I recall. Some sloppy calculations I did suggest my version would hold ~0.33ml(assuming no filling) as well. Counted ~60 puffs with my last version which would give about 4 cigs, so something isn't right here. Maybe I just don't inhale that deep.

BTW, dx sells various cigarette holders with filters. sku.8244 for instance looks promising. Others seem to have smaller built-in containers. Looks like others might hold pure e-liquid without filling though. Some might even be usable for diy atomizer. Oh well, easier to buy and see.

60 puffs would be 6 cigarettes- I get 10 puffs per real cigg, these are standard ciggs though, not hte 100's

Third version. This is for penstyle with vapor gaps on sides(forgot to draw them). Holds pure liquid as you can see. I dont think this being able to hold pure liquid makes the card hold any more but it stabilizes liquid flow and since theres that plastic support, makes good contact with atomizer. I'm using this on my sailebao(=????????????=) dse801 with excellent results. The one I'm currently using is a bit different but this should be just as good if not better. Ideally that plastic slip should be just a tid smaller than cart inner diameter so that it acts like a spring. Little gap on the bottom helps liquid to flow from side to side. Density of the filling and how deep inside cart it goes is the key factor here. Thicker than normal cigarette filter is a good start.

Unfortunatelly it is fairly difficult to make a liquid holding seal at home so it's a no go for my mini.

About the first design: doesn't the liquid easily flow down the side to the back so you get liquid in your mouth? The cotton touches the inside edge of the outer cart.

Yes there are small gaps between the plastic slip and outer cart but the cotton sucks back most of the liquid getting to the vapor cavity. I did get liquid in mouth after filling but beyond that I felt it was a problem.
