摘要: In an oscillator-exciting system for a ultrasonic liquid nebulizer, a piezo-oscillator element for nebulizing the liquid is electrically connected to a self-exciting oscillating circuit as a constituent element thereof and the circuit is oscillated at that frequency at which the electric impedance of the piezo-oscillator element is inductive. A protective transistor may be connected to a current-bias resistance of the oscillating circuit, which protective transistor may be cut off by a reed switch sensing the exhaustion of the liquid being nebulized and/or by an overcurrent sensing circuit, for ceasing the oscillation in case of liquid exhaustion and/or overcurrent.

摘要: Noise potentials and radiation in an ultrasonic nebulizer are reduced by separating the oscillator and power supply and shielding the former, with one of the DC power lines to the oscillator passing through an aperture in the metal casing that shields the oscillator, while the other power supply line is connected to that casing. Oscillator control may be achieved by an unshielded variable resistor coupled by conductors of extended length to the oscillator by a filter circuit.

摘要: A liquid nebulizer comprising a nebulizing container for a liquid, an outlet duct, and a transducer at the bottom of the container. A partition surrounding the liquid projection produced by the transducer is included, having its upper edge above the liquid surface, so that large spray particles or drops from the outlet duct fall outside the partition.
