Thinking about building an atomizer...

[naviathan]

I just copied and pasted from my post in Tips and tricks. I should have put it here first.

I'm happy with my 901 atties, but after disassembling one I think I can do a better job. I won't even go into my thoughts on the 808 cartomizers. Those things were horribly thought out as is evident by the burning cart material.

After looking over the two designs inside and out I think the 901 has the best basis. The aluminum mesh used to wick the liquid out of the cart is a great idea as it won't burn and does a great job of wicking. However, they still use a stranded wick through the middle of the heater coil. One of my atties that wasn't vaping well had turned the stranded wick in the heater coil to charcoal. I wonder how good for you that burning is? Seems reminiscent of the 808 carts problem, just not on such a large scale.

So onto my suggestions for design:

1. No more stranded/material wicks. This is obviously a single point of failure.
2. A liquid filled cart (no wadding material) with a needle puncture system for dripping the liquid into the heater chamber would allow more liquid storage, less mess and possibly easier to fill depending on how it's capped.
3. ceramic!

To make this a little clearer and using a 901 as an example. Remove the wadding material from the cart and cover it with a rubber seal with a small puncture point in the middle for a feeder needle to insert. Redesign the heater coil using a small ceramic rod to wrap the nichrome wire around (similar to a high voltage wire wound resistor). Then use the aluminum mesh to create a sheath around the ceramic heater and .... one end up to the feeder needle. When the cart is inserted like normal the feeder needle sticks through the rubber seal and begins pulling the liquid down to the aluminum mesh sheath which holds the liquid near the ceramic heater. Once the mesh is full it will pool a little at the feeder which would stop the liquid flow. As the heater evaporates the liquid more is drawn down into the mesh. The ceramic would aid in the draw due to it's porous nature. It would also assist in extending the lifespan of the heater coil because of it's thermal characteristics.

So, any thoughts?

The mesh will conduct electricity and short out the nichrome wire, so the nichrome would have to be encased in the ceramic, and then wrapped with the mesh to prevent shorting.

The ceramic coated nichrome has already been worked on.
Look for "Quit for my kids" thread in the atty section.

The mesh type attys seem to have 2-3 diff wick materials.
Most of the carbon is from the juice. If you think abt one coming out, its bigger and normally has bulges where the feed holes spray on it. The wick isn't growing to make it. As it forms, it can crack the strands. Some do have a material that just burns up similar to the carto issues.
GreenCigs "loop" so far is still the winner as cartos go. Its even easily replaceable in many models. The GreenCig G120 Cigar is a good example.

I just put a pic up in the following link and you can see that as well used as it is, there is no wick burning at all. This is why I prefer this type and silica rope or this material for my attys.
