INDUSTRIAL ULTRASONIC SPRAYING DEVICE

摘要

The invention relates to an ultrasonic spraying device, comprising a generator connected to an electro-acoustic transducer fixed to a pulveriser constituted by an axial rod (41) around which is arranged a radial crown (42) having at its outer edge a spraying surface (44), in which the material and dimensions of the pulveriser are selected such that the pulveriser vibrates in resonance at the frequency F, in a vibration mode where the rod (41) and the radial crown (42) simultaneously contract then dilate alternatively, any point of the spraying surface being animated by an homogeneous vibration orthogonal to said surface.
