This may help people understand some of the problems they are having with their PVs, JBs or other mods. I hear about the burnt taste in atty constantly, so understanding some things may help. If the wick runs dry it will taste burnt (duh) until more juice gets to the coil. Unless you drip directly on the coil that will take a little time for the wick to get saturated again. The thicker the juice the longer it will take. Put a drop of juice on a paper towel and watch it spread out
same thing is going on in your atty. I find if I have run dry, I refill and then pulse the button and do a few short in and out hits to get things going again This does three things
pulsing the button warms the juice and wick a little reducing the viscosity of the juice and the juice will attracted to the heated part of the wick. Same way wax goes up to the flame of a candle by capillary action. Also the air pressure fluctuations from the short hits helps move the juice along too. As far as that goes, I always pulse the button at about 3-4 second intervals instead of holding it down
and I rarely get the burnt taste and my attys last for months.
Some wonder why their attys get hot even though its flooding. When your atty is flooded you are using your battery power to basically boil juice instead of vaporizing it. The heat you feel is the hot juice against the wall of the atty, so you need to blow it out into a paper towel or something to get the excess out.
One other thing I am not an owner, future owner, fan or critic of the JB and other mods like it, but I think I understand the concept as I am working on something similar. This may help any others that are doing something similar too. One of the problems I have found experimenting with mine is the delivery system of the juice. Problem is when you press the bottle to deliver the juice, it goes up to the wick and when released, some will come back down unless there is a one way check valve in place. If you do that there has to be a way for air to replace the spent juice, so another valve would have to be incorporated into the system to let air in but allow the bottle to be pressurized also. One way to do it is on a juice return line from the wick area to draw the excess back down along with air. My theory on the JB flooding is that people get impatient when the wick dries and pump more than the return line can bring back. Again this is MY ASSUMPTION because I have never seen a JB personally just been following the threads. It may not even be built like that, I dont know. Another thing that could cause flooding or problems in this type of system is temperature expansion and contraction of the bottle pushing or pulling the juice when not in use. Thats why they vented sippy cups! LOL
If anybody has some good ideas pertaining to this type system I would love to hear it. If something here doesnt make sense or is flat out wrong let me know also as I am no rocket scientist and I have been wrong once or twice in my lifetime. I almost choked on that one!!
For most this has probably been understood long ago but some maybe not. Hope this help a little anyway .MOD ON PPL!!
