US Patent 11400477 Reversible nozzle in ultrasonic atomizer for clog prevention

A nozzle for an atomizer includes a plate, a piezoelectric actuator, a body, and a connector. The plate defines an aperture. The actuator is configured to oscillate the plate. The body supports the plate. The connector is configured to reversibly mount the body to the atomizer in a first orientation and in a second orientation. In the first orientation, fluid exits the nozzle along a first axial direction through the aperture. In the second orientation, fluid exits the nozzle along an opposite axial direction through the aperture.
