FIELD: ultrasonic engineering. ^ SUBSTANCE: sprayer has piezoelectric element which generates oscillations and spraying unit made of a metal string secured inside the housing. The string and the housing are submerged into the fluid under an inclination to its surface by half, one fourth or one eighth of tits length. The piezoelectric element is connected to the sound generator and excites the oscillation of the string. At a definite frequencies of the string oscillation depending on the depth of submerging to the liquid, the near-surface liquid between the housing and the string is sprayed. ^ EFFECT: simplified design. ^ 1 dwg |
