Thank you for the clear explanation of this! I just got one and I was super curious how it works because I noticed that it wasn’t using any heat, so I decided to look it up and I found your video. Again, thanks. You deserve more likes on this.
I’m glad you found my video helpful. Knowing people appreciate what I do is one reason I continue to make videos dispute my lower view and subs. Also, thanks for subscribing!
I think the ultrasonic vibrations give the water molecules enough energy to jump to a different state of matter a lot more effectively and efficiently than just letting it evaporate or heating the water to give it extra energy.
Thank you so much for your video !! Just wondering what the DC fan is used for - seems like it's not interlinked with the disc for vaporization, is it there just to cool down the PCB or the diffuser in general?
The fan is connected to a channel that blows air into the unit (where the water & diffuser is) This creates positive air pressure that pushes the mist out of the device.
yes the disc is a piezo transdicer that not only vibrates very fast but also very powerfull. i dont know the frequency and the number of watts but it seems the disc vibrates very powerfull
BG Tech: what happened when you tested the components with a multimeter or potentiometer? You didn’t say, when you turned on the unit before disassembling it, whether or not the fan was working. I’d be interested to know if it was actually shorted out. That sometimes happens with those units, particularly if they are knocked over. Sometimes moisture gets down into the thing, but it can be a while before it’s obvious that function is impaired. The other thing is that if there are a lot of minerals in the water that was used in it, it’s possible that the thing was dried right back out after getting wet, and the minerals or even salts slowly caused corrosion inside the fan. I’ll be the first to acknowledge that I may be totally wrong about this, but that would be my first guess, I’d be very interested to hear what your findings were when you tested it.
@@UserUnknown8570 : What he showed here was interesting. It is the exact same thing I saw when I opened one up. but it sure would’ve been nice to know and maybe even see the process, of him restoring the unit to functioning order; That would’ve taken nothing whatsoever from the value of the video presented so far. Thanks for taking the time to reply to my comment. It’s always a good thing to hear somebody’s actual thoughts.
I have the exact problem that this diffuser has! I need to find out how to fix it! My fan turned on for a second then stops, and sometimes doesn’t turn on at all. I would be ok with just having an on/off function only if the circuit board is the problem. And mine is new as well, used once, got it on clearance, someone returned it.
My diffuser has the same problem, I think the problem is with the low water sensor. Or is it just the ultrasonic disc that’s the problem? Do I have to replace the disc?
I wish I had a good answer but I’m not sure. I doubt it’s the disk though, it’s probably a different issue. It might be something due to it sensing the water level or the cover incorrectly.
@@BGTech1 really? I saw on Amazon quite a few with a cotton stick as filter which requires replacement every 2-3 month. Just wonder if that lasts longer?
@@lovemoraine filtered diffuser would probably make it last longer by keeping contaminants away from the ultrasonic disk, but it might be more expensive that one without it. If you use clean water you could probably get away with using a filter a bit longer than what the instructions say.
