Well this is a messy thing. It's like the Hazer Phaser, but much more portable and MUCH moister.
One correction (so far). After reassembling the unit I discovered that the microcontroller starts by ramping the motor up slowly to control the initial current peak.
I'm not sure the original purpose of this device (hair spraying?). But it has been covidulated into a disinfecting gun.
You can load it with the contents of cheap supermarket surface sanitiser and then blast most surfaces with its saturating output. Unlike the heated units this doesn't create much of an airborne haze, but instead does the equivalent of pumping the trigger on a spray gun at high speed.
I don't recommend its use near delicate electronic things, including phones and keyboards. And note that after turning it off it still squirts what was left in the armoured black tube (possibly a simple acumulator?) with decreasing force until a small drizzle sprays out the end.
One good thing about the simple diaphragm pump is that it shouldn't suffer harm if run dry when the bottle is empty.
