FIELD: process engineering.
SUBSTANCE: invention relates to distributors of fluid equipped with piezoelectric elements to accurately disperse fluid in the form of micro drops or aerosols and may be used for dispersion of aromatic or cosmetic products, etc. Proposed ultrasonic sprayer comprises rigid case of piezoelectric converter with first end that makes a hole and second end. Inner cavity of said converter has chamber to contain fluid to be dispersed. Said case has axis of symmetry, micro perforated membrane and piezoelement. Membrane is attached to first end to close the hole. Piezoelement is arranged to cause vibration of piezoelectric converter case. Piezoelement is arranged nearby said second end to cause vibration of piezoelectric converter case in direction parallel with its axis of symmetry.
EFFECT: easier control, ease of manufacture, lower production costs.
