First, note that I don't smoke. Rather I am trying to turn some KR808 E-cigs into a smoke machine for a puppet stage.
Obviously the coil is where the smoke is generated. The coil is apparently wrapped in some special stuff... perhaps wicking material that can withstand being in direct contact with the coil. Then, a separate absorbent absorbent material is wrapped around the outside of that inner wick, and provides the bulk of liquid storage.
Thus, the fluid flow is from the outer wick, then gets absorbed into that inner wick around the coil. When the coil is heated it vaporizes liquid in contact with it. The vapor then flows out through the center of the coil as air is drawn through the long hole down the center of the cartridge.
What puzzles me is the two other short pieces of woven, wick-looking stuff that above and below the coil. I am surprised that they didn't simply continue to use the same stuff that is around the coil itself. They are going to some trouble to cut those pieces and arrange them.
- Perhaps the stuff in the center is to expensive to waste.
- Another person on another thread had mentioned that liquid will flow from a less absorbent material into a more absorbent one. So perhaps it somehow controls the flow of liquid.
- Another idea is that perhaps the stuff around the coil is easily crushed. The coil keeps it out, but they needed to keep the central hole open on the upper and lower portions of the tube, and so added those two pieces of tube stuff to keep it open.
Really, these are just guesses. I want to understand better, because I may try to make my own atomizer based on the design of these cartomizers. I am hoping that I can make the smoke denser.
The atomizer I am thinking about would use a wick made from a stove gasket type material (a woven ribbon of fiberglass -it would look like shoe lace material). Then I would form a loop of this, perhaps 1/2" diameter around a core of some sort (perhaps wood dowel). A loop of nichrome wire would be wrapped around this wick so that it stays in contact against the wick.
Then, after wetting the wick with juice, I would turn on the electricity and expect the juice to get vaporized. Furthermore, since the juice would not have to travel much distance through the wick, the design would allow for a lot of vapor to produced for a longer time than a standard E-cig.
This concept may work nicely for a pipe design for those who smoke, as I understand that a pipe smoker typically doesn't inhale the smoke to their lungs. But they want a dense smoke for the flavor to be sensed in their mouth.
Do you think my design idea is valid?
