Abstract
An ultrasonic atomizer device comprises an elongate body member having a proximal end and a distal end, the elongate body member being provided at least along a distal segment with a longitudinally extending liquid guide channel. The body member is further provided at its distal end with a radially enlarged head and at least one orifice communicating with the channel at a distal end thereof, the orifice extending to an atomizing surface disposed externally to the body in a recess on a proximal side of the head. The body is also provided with means for forming an operative connection with a source of ultrasonic vibrations.
Claims19
An ultrasonic atomizer device comprising an elongate body having an inlet end and an outlet end, said body being provided at least along a distal end segment with a longitudinally extending liquid guide channel, said body being further provided at said outlet end with a radially enlarged head, said body having at least one orifice communicating with said channel at a distal end thereof and extending to an atomizing surface disposed externally to said body on a side of said head facing said inlet end, said body being provided at said inlet end with means for forming an operative connection with a source of ultrasonic vibrations.
A method for depositing a liquid substance on a surface, comprising the steps of:
- providing an ultrasonic atomizer device including an elongate body provided at least along an outlet segment with a longitudinally extending liquid guide channel;
- conducting said liquid along said channel from an inlet end of said body to an outlet end thereof;
- guiding said liquid from an outlet end of said channel to an outer surface of said body;
- transmitting ultrasonic vibrations along said body from said inlet end thereof;
- in response to the ultrasonic vibrations transmitted along said body, atomizing said liquid at said outer surface;
- and
- providing the atomized liquid with a substantial velocity component directed back towards said inlet end of said body.
