The 'Easy Puff' mod - a revolution in vaping ...

[Solace G]

As much as im despised on this forum i cant seem to drag myself away from the problem itself. It is interesting. Has anyone tested one of the suggested fans? IE, put it in a tube (no resistance required) and take a drag. I would be interested in knowing if the fans RPM increase beyond the parameters of the engine. (they almost certainly would) If so it would negate the purpose of the fan. Because part of the energy exerted by the user would be diverted into turning the fan.

So the question comes down to which is a more efficient means of suction, a direct inhale or a fan/prop? A volume test is called for. Be happy to work the numbers myself, which fan have you settled on.

What may work, and i haven't even begun to work this problem yet is using the fan not as a device for assisted inhalation, but as a means to top of the battery. Basically a micro generator. And before you give me **** for posting unfinished ideas, i have quite a few projects on my table right now but im more then happy to work it. If their is any interest in this tell me and i will begin work.

PS, To kinabaloo, apologies for jumping to conclusions, you have put alot of work into this idea.

joedirt is right, puff volume is .05 liters, not .5 liters as I said above. Sloppy math on my part - sorry.

That's great news (1-2 lpm on a 2 sec puff) that can be done with a 10x10x3 fan.

Thanks for catching my error joedirt

Indeed - it definetely makes the idea feasible.

Though I still think most vapers, if not smokers, inhale quite a lot more than 0.05? The range would be 0.05 - 0.4L. The higher figure includes all the extra air breathed through nose and after the smoke/vapor too; for example, I typically inhale about 0.1L through the PV, and a further 0.3 after that = 0.4L total (this being a 'lung inhale' rather than 'mouth inhale').

Of course, in terms of the fan assist, only that 0.1L is the important part (though I might sometimes inhale all 0.4L through the PV). I think only non-smokers inhale 0.05L A more realistic figure for vapers would be about 0.1L.

If deep breathing, volume of inhale and exhale can be something like 2-3L.

Total capacity of lungs: 5-6L; of which about 1.5L always remains inside after maximal exhale.
Normal breathing turns over about 5-10% of the air in the lungs - 0.25-0.5L.

.05L to .1L is right on the money for mouth inhalers. And .1 to .4L sounds right for lung inhaling. Which raises an interesting question. Which would the fan assist be more comfortable for? This also introduces an engineering obstacle. For the fan assist to be comfortable for everyone it will need a wide range of variability. Essentially the air volume will need to adjust from .5 lpm all the way up to 12 lpm.

I think around 1 lpm will be fine (for all user types). It would be difficult to go above that perhaps because the fan is not in open air but would be pulling air through the VPs air restriction (which is there to pull juice droplets from the metal mesh.

No need to create a mini leaf blower

I gotcha - just a gentle push of air. 1 lpm through the atty will fill the mouth in 3-4 secs. About double for a lung inhaler.

By ensuring some air flow at any time the heater coild is activated, one can reduce the chances of burning

 

[mnealtx]

But, it also increases the time needed for the atomizer to reach operating temperature - maybe some sort of delay timer?

Well guess I better put the two stroke back on the lawn mower..LOL

Just kidding but it is an interesting concept and I have been messing with the same idea, but nothing good ...yet. I have also been thinking that a bottom, fluid, delivery system might work. With the atty upsid down since the air is forcing it up. I know it's not much of an air current but in a fine mist it might work, just trying to get the correct mist pattern.

I'd be curious to see it but I have a feeling that if vapor went down our throats without the internal feedback we use when we puff, that this would cause choking, like a vapor version of waterboarding.

Touch switches have been around in my industry for 35 years. Usually capacitive, cool to use and in the end, unreliable.

I'd like to be shown to be wrong about this.

 

[Skeezix]

How about something like this?

It's a small handheld vacuum. Just rewire it to run backwards.

 

[styler]

How about a temp sensor that turns on fan when atty gets warm, and shuts off when cool.

Looks like someone is is reading your mail kinabaloo, or is this yours?

USPTO Application #: 20060196518
Title: Flameless electronic atomizing cigarette

Abstract: The invention relates to a non-smokable electronic spray cigarette which only comprises nicotine without harmful tar. The cigarette includes a smoke mouth integer comprised with a shell, a cell, a high frequency ionzer, nicotine solution storage and its container, control circuit, a display screen, a human contact sensor, a piezoelectric supersound atomizer, a high temperature vaporization nozzle and attachments, an electro-thermal vaporization nozzle installed in the air suction end of the shell goes through an electric control pump or a valve with a measuring chamber and a liquid storage container which contains nicotine solution and is connected to the electric control pump or a valve with a one-way flow valve, the control circuit plate has four export ends individually connected with the high frequency ionizer, electric heater, pump or valve and the display screen, a human resistence sensor and an air flow sensor are connected to the input end of the control circuit. The advantages of the present invention are smoking without tar, reducing the cancerogenic risk, the user still feel smoking and experiercing the excitement, the cigarette is no need to be lit and is no fire danger.
