Is there a better atomizer design?

[Trumpybloke]

Porous ceramic sounds great , but I am a little worried about it blocking over time, all liquids will have some sedimentary matter in them unless they are of laboratory purity ?? There is also the matter of heat,vapour, blocked pores,expansion, and explosive ( minor I am sure ) deconstruction if liquid is trapped in a pocket ( that's being very alarmist I know )
Actually the further I delve into it , the more I am convinced a method of dropping straight liquid into a carefully designed conical nichrome coil where it can flash vaporise might be the go ? no wicks , nothing to get clogged, just a drip and PHWOOF !! lol

But there is alredy a ceramic pieace in the atomizers maybe it dosnt need to be porous, just regular ceramic just to transfer liquid from the deposit to the coil via capilarity, whatever we use, it must be something easily replaceable, so when it gets a little burned we can just put a new wick on it, if we use a wick a good idea is to make this wick external and coupled with the coil just when it is going to be used.

I should add that these are purpose built ceramic wicks, 4mm diameter if i remember correctly. Just wrap the wire around it and away you go.

Trumpy - perhaps best way to do what you suggest is with a simple zozzle to fire a mist towards an open coil, perhaps by some kind of mini electrical pump. Or the mist could be created by a miniature piezo transducer as you find in some battery operated air fresheners that periodically fire out a mist. Some kind of hot plate rather than coil would be more robust and long-lasting - perhaps ceramic or graphite.

Vageorge - have you tried this out (ceramic wick as atomiser coil core) ?

Ohh! this is exactly what we need, look at the flexible heaters!

A round heater with a ceramic wick in it might do the job!

Thanks Vageorge

I personally think there ought to be some more development in better functioning wadding in the carts...

Sealed refillable fluid cartridge with wick protruding into fluid. Wick is porous ceramic tube. The heating coil is inside the ceramic wick and heats the inside wall releasing vapour which is sucked up the top and out the bottom. A filter membrane sits on top of ceramic/element to only allow gases to pass through, preventing unvaporised fluid from getting into mouth. Damaged coils easily slip out for replacement.

Is that one of those flexible heaters in there Vageorge?
Wow, you might be on to a great way to build the e-cigs ourselves, including atomizers! I will be very interested indeed to see you actualy build this and telling us how it goes.

That looks like it has potential Vageorge. I like the fluid resoviour from the picture but can't get the links to work for some reason.

Edit- nevermind.... THANKS Lithium!
