battery design or lack there of

[Mary Kay]

Who's idea was it to stack a battery with a hole on top with an open ended atomizer that needs to be damp?
I have rechargeable batteries for my camera and they don't have holes in the top. Maybe the hole needs to be there so you can stick a paperclip in there to ajust the floating post..that goes from side to side as well as up and down. yeah..there's another winner. What pray tell is the point in that?
Couldn't the atomizer be the floating part? Why both? Why any?
Now since I am just the consumer, in no way current on battery design, I ask that some of you really smart people explain it all to me.
Thank you.

The automatic switch is a vacuum switch, activated by the indrawing of air when you take a puff. So the hole, that allows the air passage, is of course necessary for the ecig to operate. That's why you have the hole in the bottom of the atomizer too. And, that's why you can have a sealed battery compartment when there is a manual switch operated by a push button. No need for the air flow.

I don't know if the newer mic auto switches need the airhole, but it could well be that they need it too.

I guess it worked better than a sliding "plunger" type assembly that would pull up the battery contact until you were done puffing.
That was my idea.

YVilla! Thanks, I knew there must be a reason for that idiotic setup. I guess I see a manual in the future!
Why then is there a movable post?

Sorry to ignore that part of your question, Mary Kay.

The center post is the positive electric connection, where the positive wires are connected. So the center post of the atomizer must meet the center post of the battery in order for the electrical connection to be made and the ecig to work.

But those center posts must be kept insulated from the metal of the threads, which is where the ground wires are connected. So the center posts are set into an insulating material - silicone or some type of plastic, to keep them them from touching the rest of the atomizer or battery metal.

I'm not 100% positive on why those center posts are kept flexible instead of being fixed, but I'd guess it's to allow for minor tolerance differences - as when you have hundreds of thousands of atomizers and batteries being made, it's not surprising that some small differences creep into the manufacturing process.

If the posts were totally fixed in place, then if you got an atomizer with a small size difference in the vertical placement of the center post, for example, it would not make contact with a battery center post, and thus wouldn't work at all. With the "floating" center post, you can adjust it to make the required contact.

Any other guesses?

Once again you made me understand. You are good at explaining Yvilla!
Maybe you should do a book..Yvilla explains it all to you! LOL
Thanks for taking the time.

yvilla is getting pretty good... he he

yea, nicely put yvilla ...

Just for shows , heres a centre contact removed , you can see the silicon insulator :

ApO.

just to add , manual e-cigs also need airflow from somewhere. the SD has a 901 atomizer which has the hole in the side, the pen atomizer has them in the atomizer threads. No airhole/airflow , manual or not would be like sucking on a blocked straw , you just wouldn't be able to use it. I found that out with the loongtotem adaptor i made first time. You CAN use too much solder
