  • Publication number: 20200130007
    Abstract: A step cavity low-frequency ultrasonic atomizing nozzle includes an air inlet casing tube, a water inlet casing tube, a de Laval valve, a fixed cap, a first adjustable base, a tapered rectification sleeve, a vortex flow impeller, a stepped resonance tube, an adjustment plunger, a positioning screw, and a second base. The adjustment plunger is located within a second step hole of the stepped resonance tube, and the axial position thereof is adjustable. The vortex flow impeller is fixed on the stepped resonance tube via a bearing, and an outer tapered surface thereof attaches to an inner tapered surface of the tapered rectification sleeve.

  • Publication number: 20190054492
    Abstract: Disclosed is a piezoelectric two-phase flow ultrasonic atomization nozzle, comprising a piezoelectric vibrator (6), an amplitude transformer (8), a second end cap (12) and a first end cap (14). The piezoelectric vibrator (6) and the amplitude transformer (8) are connected via a connecting bolt (4). An air inlet connector (2) is installed at a tail portion of the connecting bolt (4). The second end cap (12) is fixed to the front end of the amplitude transformer (8). A Laval type valve core (9) is fixed in a stepped hole of the amplitude transformer (8) and a groove of the second end cap (12). A liquid inlet hole (10) is arranged in a wall face of the stepped hole of the amplitude transformer (8). A plurality of flow guide holes (11) is formed at the positions, close to an outlet, of the Laval type valve core (9) in the radial direction. The second end cap (12) is connected to the first end cap (14) in a threaded manner.
