Technical field
The present invention relates to atomization of liquid technical field, relate in particular to a kind of ultrasonic focusing liquid sprayer.
Background technology
Ultrasonic liquid sprayer at present commonly used has two kinds of hydrokinetic type and piezoelectricity change types.Hydrokinetic type atomisation flow is big, but the energy conversion rate that atomizes is low, and particle grain size distribution is inhomogeneous.The atomizing of piezoelectricity change type is vibrated high-frequency electromagnetic and is converted into the ultrasonic wave of same frequency, and good to the atomizing effect of liquid, it is even to generate particle size distribution.Existing piezoelectricity change type sprayer generally is by PZT (piezoelectric transducer) the electromagnetism concussion to be converted to ultrasonic vibration, and the vibration that utilizes large amplitude again is with the atomization of liquid.Usually adopt ultrasonic amplitude transformer vibrational energy can be assembled, and use the ultrasonic amplitude transformer of cascade to strengthen gathering of vibrational energy, can improve the nebulization efficiency of liquid.
Summary of the invention
The present invention seeks to: a kind of ultrasonic focusing liquid sprayer is provided, and it is simple in structure, and focus ultrasonic is effective, can produce the spray effect that distributes very evenly.
Technical scheme of the present invention is: a kind of ultrasonic focusing liquid sprayer, the transducer that comprises liquid container and be located at the liquid container outer surface, described liquid container is provided with feed pipe, described transducer is a focused transducer, the focal area of described focused transducer is dropped on the chamber wall of described liquid container, and the chamber wall of described liquid container around in the focal area is provided with some micro-spraying holes.Transducer focuses in the focal area, makes that the liquid in the liquid container also focuses in the focal area under the effect of sound wave, and goes out from micro-spraying hole is injected, forms equally distributed micron order atomization of liquid particle.
Further, in above-mentioned ultrasonic focusing liquid sprayer, described transducer is a sphere shape transducer, and the centre of sphere of its sphere is located in the focal area, and the chamber wall of described liquid container is provided with the sphere shape position with sphere shape transducer form fit.Except above-mentioned sphere shape transducer can be used as focused transducer use of the present invention, it can also be other any transducer or transducer group that can focus at the place, focal area, this part chamber wall such as liquid container is sphere shape or other curved surface shaped or multiaspect shape, which is provided with the less transducer of a plurality of volumes (as composite transducer), all transducers focus at the place, focal area.
Further, in above-mentioned ultrasonic focusing liquid sprayer, the diameter range of described micro-spraying hole is at 3～30 microns.Different micro-spraying hole apertures can spray the atomized particles of different sizes, can determine the size of micro-spraying hole according to actual needs.
Further, in above-mentioned ultrasonic focusing liquid sprayer, described micro-spraying hole is located in the border circular areas, and the center of circle of described border circular areas is the center of the focal area of focused transducer.The size of this border circular areas is determined according to the size and the actual spraying needs of sprayer.
Advantage of the present invention is:
1. the present invention uses focused transducer to produce the ultrasonic wave that focuses on, and then makes liquid focus at the spout place, and it is simple in structure, and focusing effect is good, can produce equally distributed micron order atomization of liquid particle.
