Guys, I need your help. What causes or how does the coil of a vape get current when you inhale. Like what happens for the circuit to close when you inhale so that the coil gets hot. Please explain someone.

Thank you very much, I'll check it out

 

Hello,

Hi,
See Big Clive on YouTube.

What I have observed in dissecting vape devices is a switch operated by the suction of sucking air thru it. Cheap and fragile and subject to being stuck in the ON mode. But it is a vacuum switch operated by the air flow.

 

When you inhale on a vape, you activate a sensor that completes the circuit. This allows the battery to send power to the coil, heating it up and vaporizing the e-liquid. The process is similar to flipping a light switch, where your inhale acts as the switch to start the flow of electricity.

Welcome to AAC.

This explanation is so vague it doesn’t really add anything. A “sensor“ completes “the circuit”? What sort of sensor? What circuit? The light switch analogy might as well be reduced to “it gets hot because electric current appears in the coil when you suck on it”, or perhaps, “it’s like a garden hose, the valve is opened when you inhale and the water is like the electricity”.

Take a look at the article Bertus posted above, or the two linked Big Clive videos. You should always read through a thread before posting an answer that might be redundant already.

 

In the few vapor dispensers that I have dismantled, that "sensor" looks a lot like a very small electret microphone cartridge. It is actually a small normally open vacuum switch, about 0.2 inches diameter at most. I have not taken one apart to see how they work. The power source is a small battery, often about 3 volts. I am not sure about what the battery technology is. Lithium or carbon-zinc or something else.
The really nasty danger is that long after the vapor device is discarded, thrown on the ground, there is still enough energy left to start a fire if it gets crushed so that the witch stays closed. So it could start a fire in a trash bin or a pocket or any place, if it were stepped on incorrectly. Almost as dangerous as a burning Butt tossed out of a car window.

 

Big Clive on YouTube has taken apart and analyzed many vapes. You will get some good info from videos

Many disposable vapes have rechargeable LiIon batteries inside. Clive shows how to safely salvage these.

Don't feed the bots.

 

My response to "Y" was supposed to be here, post #12 instead of #9. "The Circuit" is a very simple one series loop, from the battery positive to the vacuum operated switch tht looks like a small microphone element, to one side of the heater element. From the other end of the heater element to the battery negative terminal. A very simple circuit. For some versions there may be two heaters.

Ditto. I've found a few laying by the road and dissected them with findings like you reported. I was frankly surprised that such a small switch is controlling such a high current.
