Hi again Marduk,
That's correct. Ipuffusa confirmed it earlier. The air comes in through the opening around the USB port and travels past the coil supports.
Noted!
What we don't know... ... No can do.
Well, quite honestly, considering the clear statement which you've just made previously, euh...
There's no need to look any deeper as i don't expect the air paths to be contained and separated under the present circumstances. So, thanks again! You've been really helpful, at least to me!
ADDENDUM
I was on the toilet seat, having some inspiration induced by
the idea of venting electronics i guess, well... A revelation arrived quite suddenly!! No matter the fancy luminostatic heat regulator!
But i've got to wonder then! Who would want to ruin a genuinely creative concept like this one??
Considering in this specific case we've learned that the fresh air opening is from a USB port!...
So, there's no going around that unless the manufacturer found a USB connector designed for such dual-purpose function, e.g. with a separate/sealed air path. Another possibility might be that this is built around standard connector hardware though there's proper sealing, possibly silicone or teflon, etc.
Anyway, who on earth would want to spoil it by design!? So i thought to myself airtight isolation from electronics (in the mystery black box) could still be implemented using a tube just as in the PuffIt device: a tube brings fresh air from outside the casing. In addition, pressure detectors remain compatible with airtight containment if, for example, there's only a small metal ball partly obstructing a plastic tube probed by some magnetic pickup coil: the machine's fresh-air inlet would only make contact with tubing and a metallic body before it enters the heater section...
Yet, there's that peculiar multi-purpose USB inlet port.
That's no accident, is that USB inlet port actually intended for venting electronics too? I mean, really?!
...using the power of our own lungs???
Please, PLEASE... Please tell me i forgot a happy scenario somehow!!
