Bottom Feeder Question.

[vereybowring]

I have been considering the different ideas people have had for bottom feed juice boxes and have a question relating to it.

For hygiene reasons a needle meant for syringes is a good choice for the attie end and people tend to squeeze their bottle or have a pump bottle.

I think my idea might work but want to throw it open to all.

If you got a fine enough needle say 27 Gauge, and fitted this to the atomizer end, and obviously a wider tube for the battery connection, would Bernoulli's principle come into effect when you inhale and heat the atomizer ?

If it did you would not need to pump at all as the fluid would naturally rise up the tube and feed the system.
Trees use this to pump sap up their height using the evaporation effect from their leaves after all.

I am just not sure of the needle size you would need for this to works.

I just hope there is some smart chemistry/physics/biology type person on these forums that could have a think about this as I propose this would make bottom feeding much easier and cleaner (should be no flood risk after all).

Answers not on a postcard, here will do just fine !

LOL you lost me at the Bernoulli's principle

Are there feeders with a pump feed ?

[faghag]

OMG, and here i was pondering over what the **** an attie might be, and how a ecig can flood...

i'm out of my depth!

Lord knows Verey, I'm with Faggie on the technophobe step . . . but I do have a Bottom Fed Juice Box made by one of our lovely members with the needle fed system and it works very well.

LMAO...

I think you're looking too hard in to it!

Bernoulli gets applied to aircraft for lift etc. and rockets for velocity. Not sure how it would assist ecigs though! Also, to get the increase/decrease in pressure, you'd need to widen/slim the feed tube. You'd have to do this seemlessly or you'd get 'eddies' in the flow and then the entire principle changes. To achieve this, you'd need a custom made 'funnel' and that would probably make it unworkable from a cost/effort point of view.

Yup the reason I am confusing everybody is I'm being an idiot.

As pinhead mentioned Bernoulli's is more to do with vacuum flows and aerodynamics.

I should have been talking about capillary action !

So, does anyone have any input on using narrow tubing and capillary action to raise liquid naturally to an atomizer without having to manually pump it by squeezing a bottle or similar ?

[Scylla]

Capillary feed sounds a very good idea, Verey - work on it!

[mrlimbo]

How would you stop/start capillary action ?

[magicma]

I had a chuckle at the title of this thread..... I wondered why Verey wanted to feed his bottom!!!

Just ignore me!!! MM

[vereybowring]

I have a rough diagram -



Capillary action would have to be primed by making sure bottle connection with tube is airtight, you then blow a little air into the one way valve on the bottle forcing the first drops of liquid up to the wick and atomizer.
After priming in this way I think the system should self feed but obviously can't be completely sure since I'm not a scientist - just a mad vaper.

Tut,was just going to explain it to everyone in laymans terms but Sean beat me to it,never mind,i taught him well.
NNN

This idea has been put on a future development timetable as I just found out about the genesis style atty, so I'm going to build my own genesis tankomizer with syringe tubes and a self built atty.

Just need to get a nice chunk of delrin rod to make a connector piece/atty mount to separate the two halves.

For those unfamiliar the genesis uses a tank with a fine steel mesh wick running up to a repairable atty coil similar to a Bulli A2 but instead of using silica/glassfiber as a wick you have the coil round the mesh wick (oxidised in advance so it doesn't short out).
