Piezoelektrick\u00fd jev a generov\u00e1n\u00ed ultrazvuku<\/p>\n

Z\u00e1kladem funkce ultrazvukov\u00e9ho atomiz\u00e9ru je piezoelektrick\u00fd prvek, obvykle keramick\u00e1 desti\u010dka z materi\u00e1lu jako je nap\u0159\u00edklad titan\u00e1t barnat\u00fd. Tento prvek m\u00e1 schopnost m\u011bnit svou mechanickou velikost v reakci na elektrick\u00e9 nap\u011bt\u00ed a naopak. Atomiz\u00e9r aplikuje na piezoelektrick\u00fd prvek vysokofrekven\u010dn\u00ed st\u0159\u00eddav\u00e9 nap\u011bt\u00ed, typicky v rozmez\u00ed 1,7 MHz a\u017e 2,4 MHz. To vede k rychl\u00fdm vibrac\u00edm desti\u010dky s frekvenc\u00ed odpov\u00eddaj\u00edc\u00ed frekvenci nap\u011bt\u00ed. Tyto vibrace se p\u0159en\u00e1\u0161ej\u00ed na kapalinu um\u00edst\u011bnou na povrchu desti\u010dky.<\/p>\n

Rozpra\u0161ov\u00e1n\u00ed kapaliny<\/p>\n

Vysokofrekven\u010dn\u00ed vibrace piezoelektrick\u00e9ho prvku vytv\u00e1\u0159ej\u00ed na povrchu kapaliny vlny s velmi kr\u00e1tkou vlnovou d\u00e9lkou. Tyto vlny zp\u016fsobuj\u00ed vznik kapil\u00e1rn\u00edch vln, kter\u00e9 se postupn\u011b zv\u011bt\u0161uj\u00ed a nakonec se rozpadaj\u00ed na mal\u00e9 kapi\u010dky. Velikost t\u011bchto kapi\u010dek z\u00e1vis\u00ed na n\u011bkolika faktorech, v\u010detn\u011b frekvence vibrac\u00ed, viskozity kapaliny a povrchov\u00e9ho nap\u011bt\u00ed. V\u00fdsledkem je jemn\u00e1 aerosoln\u00ed mlha s pr\u016fm\u011brem kapi\u010dek v \u0159\u00e1du mikrometr\u016f.<\/p>\n
