Piezo atomiser?

[Vageorge]

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?

Just wondering.

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.

[kender]

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

[Laredo7mm]

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.

[kinabaloo]

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.

That picture came from this thread:

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)
