i tried to firm pressure to the top piece but it didn't worked..i dont have problem with spit or leak..my atomizor now doesnt have airflow and refill hole. I tried to twist it back but it turns a bit and then stops. I appreciate your help!
See what is the shortest distance to the correct position and twist in that direction.
Firmly grip the top ring (should be the most resistance part) and with something rubbery grip the chimney and twist.
Having the top cap could also help but I doubt.
