An ultransonic atomizer for liquids comprises a piezoelectric transducer (16) mechanically coupled to an amplitude transformer (20), an atomizing disk (21) mounted to the free end of the amplitude transformer (20), a housing (22) enclosing at least the amplitude transformer (20) and a cap (30) supporting a sieve-like diaphragm (31). The cap (30) is so mounted to the housing (22) that the diaphragm (31) rests on the atomizing disk (21). The cap (30) consists of two mutually concentric cap parts (32, 33) of which one (32) supports the diaphragm (31) and the second (33) serves to mount the entire cap (30) on the housing (22). A spring (36) is so mounted between the two cap parts (32, 33) that the sieve-like diaphragm (31) is held elastically against the atomizing disk (21) and that the opposing force from the spring (36) thereby is transmitted into the second cap part (33) fixed in the housing. Such a liquid-atomizer is characterized in that the diaphragm (31) always rests with a precisely defined prestressing on the atomizing disk (21), whereby operational reliablity heretofore not yet achieved with the previous ultrasonic liquid atomizers is obtained.

An ultrasonic atomizer for liquids, comprising a piezoelectric transducer mechanically coupled to an amplitude transformer; an atomizing disk mounted on a free end of the amplitude transformer; a housing enclosing at least the amplitude transformer; a cap supporting a sieve-like diaphragm and mounted on the housing so that the diaphragm rests on the atomizing disk; said cap (30) consisting of two parts mounted mutually concentrically, an inner first cap part (32) supporting the diaphragm (31) and an outer, second cap part (33) serving to mount the entire cap (30) on the housing (22); and spring means (36) mounted between the two cap parts (32, 33) and biasing them in mutually opposite axial directions in such a manner that the sieve-like diaphragm (31) is held elastically against the atomizing disk (21) and that the opposing force from the spring means (36) is transmitted to the second cap part (33) fixed to the housing.
