Anyone know what this is from? Could be the solution for a long life atomiser.
It's from an old (2007) Ruyan Cigar (Bling).
In this forum they now cut a newer model and there was no piezo anymore..
A piezo would use a lot less power so battery life would definitely go up.
The control could be a surface mount 555 timer, just find the right frequency. It could be small enough to fit inside an old atomizer.
Your starting to give me ideas....If only I had some free time these days
Hey all, new here. Great site. I have been thinking about this also, but I must admit, I am an electronics ...... I understand the 555 timer deal, and how to get different frequencies, but they only output 200ma. All the piezos I have found are from 5 to 15 watts.
So would you have to run the output from the 555 through a transistor and have that act as a relay feeding the piezo with a higher current?
Also, have you thought of any self tuning circuitry for when the piezo is under load it will increase the current/voltage automatically to keep it at its resonant frequency?
I believe the tiny piezo elements would take a small current. As in the photo, the piezo is not creating the vapor but feeding the atomiser. I have thought about this too as it could be more reliable than wicking.
Thats what I was thinking, through a transistor.
I could be wrong but I thought the first e-cigs used the piezo to vaporize but it was easier to mass produce using heat to vaporize instead of vibrations
That is interesting to use a piezo to feed the atomizer. I was thinking more along the lines of Kender and using the piezo to do the vaporizing. They have commercial nebulizers out there using this technology, but they are about $200 and a bit big. I found some piezos that I think would work (about 15mm diameter), but I am just stuck on the electronics. I can handle the Mechanical Engineering stuff, but not the Electrical Engineering.
Also, I was wondering how well the vaporization would be with the piezo and using currently available e-liquids. I think the e-liquids might be too thick for the piezo. Most of the nebulizers I looked at were only designed for specific types of medicine (albuteral) which has about the same viscosity as water.
Not sure, but the iezo frequency might need to be tunes to the juice viscosity; how accurately I dont know.
The piezo creates a mist of tiny droplets as opposed to gas. The 'vapor' we see as looking like smoke is the VG/PG recondensed back to a mist.
Cool room humidifiers show what can be done. The coolness may not feel so good in an e-cig.

It looks like Steffen later says it's not a piezo element after all.
I think that's the vacuum switch he's pointing to? Maybe some kind German fellow can translate it better than Babelfish
The busted piece on the bottom kinda looks like a piece of the brittle little ring that seals up the bottom of the atomizer mesh against the steel tube (not electrically connected)
