New design and prototype for vaping one week without refilling

[kender]

A cartridge that lasts a day would be great much less a week!
That would be nice. Different adapters to fit any e-cig. Keep up the good work

kender - thanks for your feedback.

I will try to prototype a one-day cartridge. I am hoping it will only need to be marginally larger than the present cart size for 901.

And the supply is stable and consistent; with a vape quality equivalent to operation at the peak performance time when dripping. The space required is only a little more than the liquid container's size.

However, this would require a mould for a new plastic shell - not a small matter.

That sounds really exciting kinabaloo! You've obviously made substantial progress.

A few random thoughts:
I was thinking more about the atomizer too and realized that mine have a steel wick. If I keep that moist, there is no need to drip into the atomizer.

I just read another post about polymorph and the first thing that came to mind was whether I could mold my own longer cartridge with an inner cylinder that would hold 1.5ml of liquid lol. (I'll probably never do it.) Anyway, maybe this product would be helpful with your prototype.

Since most of us would be thrilled with a 24-hr ecig, reducing the number of batteries could be an option in the user friendly design. It would also be a significant way to reduce the weight.

Keep on tinkering and don't be surprised if you need to file a patent real soon. As far as I'm concerned, the person who eliminates the constant need for cartridge refill/replacement is sitting on a bonanza

p.s. Yes, my name is revealing. I'm so bad I'd hug a prototype built in a 1-gallon paint can if I had to LOL...just at home of course.

ChainSmkr - Happy to hear from you.

I am just using AA cells as that is what i have handy. It's not part of the design; any high capacity cells suitable for the casing will do. Battery technology is improving all the time. So I am focussing on the juice delivery.

The prototype has been going well all today, so I am sure it will keep going till the juice runs out, next weekend.

To make a cart requires fine details that I doubt could be achieved with that material you mention, but it sounds ideal for other purposes. I think i can get 1.5-2ml inside the existing cart size. The clever part is in getting it out That's why the internal 'cart in a cart' is so small in traditional 901s; just making it bigger would not work.

Tomorrow I'll try a rough prototype to check functionality, capacity and sizes - then maybe see if I can convince someone with tooling abilities and equipment to make a proper one for me In metal rather than plastic, because that's easier to do at this stage.

Congrats kinabaloo!!! keep the good work!

your one clever bloke!

After a night's sleep, the 1-week vaporizer is still going strong

DaveyRoots - I am just trying to address the deficiencies in what is basically a great product. I find the carts just don't last long enough. Then there's the problem that juice delivery can be quite erratic.

Progress today :

Utilising the dimensions of the existing cart size for a 901 I can achieve a doubling of juice capacity. Am considering a longer cart to reach a volume sufficient for one day's use. This would require the cart/mouthpiece to be about twice as long.

The diameter of the vaporiser tube and the need to have an air path too makes it hard to get enough liquid volume in a short length. A plastic bottle containing 10ml (one week of juice) is no longer than the cartridge and only just over twice the width. I am considering whether there might be an aestetically pleasing way to design the casing so that it could 'work', in terms of look and feel, as an accessory to existing vaporisers.

have you tried just using a gravity fee system? I would think that if you could get a small tube into a bottle and the other end into the polyester - as it becomes dry it would draw liquid as needed and eliminate the need for the other button.


oops, re-read some of the other posts and i see you are moving in that direction - or a similar approach without user intervention.

Very happy to see your progress!

hi georgini,

Your idea os a clever one. Thanks for that I 've been sitting here thinking why it cant work but didnt find anything yet. Only that the user will need to not mind possibly getting a taste of the fluid after setting up the liquid reservoir. These days I have my hands covered in the stuff and drink as much as i vape! Luckily i mixed up a 0% nic mix

i think the main reason that only half of the standard 901 cart case is used for the juice is that more liquid than that, because of it's weight, would leak out; as long as the case is small and narrow it will stay in place, more or less.

Although twice as much juice is in one way great, it is not so dramatic that someone would buy it i think - at least not until it is mass produced. I saw mention just now reading the forums of EastMall's EM901 having a larger juice capacity cartridge; if anyone has that, I'd be interested to hear how it is different. I am going to test my new cartridge in-situ shortly and see if the superior feedthrough i expect is noticeable in the vape.

For the larger version utilisation I am leaning to something aimed to work with a USB passthrough. Either itself, or pluggable. Still working out the best way to allow easy fluid change, and atomiser connection or its own atomiser.

Although my prototype doesn't noticeably leak if turned upside down for a minute, it might leak over some hours, so it is ideally suited to a desk/table sitting design.

The tricky part of the goal was getting the fluid to the atomiser fast enough - especially important with USB or power pack (as opposed to 901 battery). I think i have a good solution for this now but finishing the design (product design aspect) is proving tricky; still, early days ...

ps : georgini - flow would depend on the level of the fluid in the reservoir even if it is connected at the bottom. Assuming you mean the way you can drain a container by tube from the top.
