Ultrasonic atomisers?

[Kate]

The original Ruyan ecig patant uses ultrasonic technology to make a mist but we ended up with heating elements making vapour.

I don't know the reason for changing the design but just with a quick look at ultrasonic humidifiers I would guess that it's not as effective or safe as our current method.

Ultrasonic humidifiers make a cool mist which includes impurities from the liquid, viruses and bacteria are not neutralised in the process.

There is an illness called 'humidifier fever' - "It is a flu like illness marked by fever, headache, chills myalgia and malaise but without prominent pulmonary symptoms. It normally subsides within 24 hours without residual effects,and a physician is rarely consulted. Humidifier fever has been relate to exposure to amoebae, bacteria, and fungi found in humidifier reservoirs, air conditioners and aquaria." HUMIDIFIER FEVER is a respiratory disease caused by an immune reaction to inhaling aerosols containing various organic materials

So maybe we are better off with the heating, vapourising method instead of cool mist?

most common humidifiers use heaters which actually can aid the growth of bacteria in the resevoir. Very much designed like our current e-cigs.

 

[Kate]

The vapour doesn't carry the bacteria or impurities though, they get left on the wick apparently.

like with a cannabis vapourizer?

 

[Kate]

I wouldn't know about that ...

 

[jigtg]

ultrasonic elements are fragile and break if dropt. they need high voltage(+-12v), which is nontrivial to produce in such a small device.

Nope cannabis vaporisors pass hot air over the plant material from a heating element. They need to generate a temp of 180 to 200 celcius to vaporise the THC. Yes I have one

It seems the Ruyan V-8 pen style ecig has an ultrasonic atomizer.

You don't really believe that, do you? I don't. Betcha it's the same old nichrome wire atomizer, with no longer a life than any other of similar design.

 

[Kimmiegrif]

there has been one review that someone said no better. but I would like to hear more about the tech and how it is better than others, and try it myself before I have an opinion.

 

[Kate]

I'm not convinced that Ruyan have produced an ultrasonic atomiser, from the account of an experienced member here they are no better than other atomisers.

Unfortunately some sales people will tell all kinds of untruth to sell their products. They take us for mugs but don't realise that you can't fool all of the people all of the time.

I think the sound of an ultrasonic atomizer would drive me over the edge. And before you all jump up and say "you can't hear it, it's ultrasonic!" - I can . . . maybe I'm a dog

You have been caught, Batman!

But seriously, these transducers switch at rate of 300kHz-4mHz so there is really no way you could hear it. How high frequencies can you hear?

 

[coinmaster]

Well, I don't know the technical details, but I used to work for a company who sold ultrasonic cleaners - it was fortunate that I worked in another area of the building, but those things just about rattled fillings out of my teeth.

I can hear other things which people find a bit strange - like I can hear the TV when it's muted from the room next door - no one else I mention it to can hear it.

I'm a professional musician, so I guess my ears have been subjected to the full gamut of frequencies for the last 30 years or so

I guess all I'm trying to say is that if e-cigarettes used ultrasonics, I would probably steer well clear of them . . . I'm sure the performance would be totally wicked, but it may come at a cost - my sanity!

Hi Coinmaster,

I too can hear things that most people can't and they all think I'm nuts ! Dog whistles, older type alarmsystems, TV's, various other electrical appliances etc. can be awfully painful to me, no idea why. I do remember though, eons ago when my ears were being tested at school, those people couldn't believe my hearing range either .

I too would be worried about the sound an ultrasonic atomizer might emit, although at the same time I'd be very curious too. Probably so much so that if the atomizer got good really reviews, I would try it out anyway to see if it'd be a problem or not.

By the way, I'm not a musician ...

Cheers,
Silver

PS By the way, been wondering whether we're already 'acquainted' ??

 

[jigtg]

Human ears can usually hear up to 20kHz. Ultrasonic cleaners switch at a rate of around 30-50kHz. I doubt you could hear anything higher than 50kHz or so.

 

[coinmaster]

Thanks jigtg. I must just be imagining it then.

PS. Silver, yes, I am who you think I am

PPS. I have a Ruyan V8 in my collection, and it's just the same as all the other penstyle atomizers, apart from the fact that it only produces little wussy wisps of vapour, and is, in comparison to the Janty, totally useless.

 

[shawnp1]

coin u have the same experience as i did with the ruyan, they are extremely wimpy.

 

[shawnp1]

i dont like to put down other companys products but i wasted alot of my money on a ruyan v8 so i know that they seriously arent worth the money. u could buy 3 pen sets from any supplier selling generics and be a mile ahead then u would be with the ruyan.

 

[coinmaster]

Yeah Shawn, the first e-cig I bought was a V8. I guess it was an OK introduction to e-smoking, but since then it's been an expensive trip finding the "one"
