I keep thinking of how to harness a simple, long standing system close to the heart of all us ex analog smokers.......the simple re-fillable gas lighter. The more you think about it the more atractive the idea becomes!
A cigarette lighter, in one action provides both an adjustable flow of liquid gas and (if electric) an ignition spark.All this contained in a very small unit.
So adapting this existing technology;
One depression of a switch would both release a pressurised (adjustable) aerosol of juice directly onto the heater coil,itself having been energised by the same switch,just as in a lighter.Length of vapour production required would simply be controlled by how long the switch is depressed.
Now for the problems;
The unit would have to be larger (but not much) to incorporate a suitable battery power source (allmost certainly L-ion) together with its charging /protection circuit.This would allow simple plug in charging as per a mobile phone.
Now the really tricky bit,what could one use ,that is non toxic as the pressurised propellant to propel the juice out of it's container.The resultant atomised cloud would be both adjustable in volume (just as a lighter) and allready in an optimum condition for the heater coil to vapourise.Not only would this greatly reduce power requirements (less energy to vapourise an aerosol than a liquid) but would completly solve the "leak" problem of other juice delivery methods.
So........what would act as a safe and currently available propellant??
What do aerosol food dispensors (such as whipped cream) use?
If such a propellant currently exists then replacement cartridges of say 10ml would give a weeks use
