Description
Technical field
This utility model relates to supersonic changer element technical field, particularly relates to the atomization of a kind of corrosion-resistant ultrasonic transducer
Sheet.
Background technology
Soniclizer utilizes electronics high frequency oscillation, by the high-frequency resonant of pottery atomizing piece, converts electrical energy into super
Acoustic wave energy, liquid water molecules structure the most just can be broken up and produce the water smoke that nature is elegant, is not required to by ultrasonic energy
Heat or add any chemical reagent.Ultrasonic atomization process discharges substantial amounts of anion, smog that can be floating with air,
Dust etc. produce electrostatic reaction so that it is precipitation, can also effectively remove the harmful substances such as formaldehyde, carbon monoxide, antibacterial simultaneously, make
Air is purified, and reduces the generation of disease.Pottery atomizing piece is as the core component of soniclizer, in use
Need to contact with liquid for a long time, under the effect of ultrasound wave, there is cavitation corrosion；Under the effect of alternating current, there is electrolysis
Corrosion；If containing other chemical substance such as disinfectant, acetic acid in liquid, there is also chemical attack.Three kinds of common effects of corrosion,
Extremely easily electrode breakages is fallen.In order to prevent electrode to be destroyed, current solution mainly has three kinds, is electrogilding respectively
Belong to nickel, titanizing, high temperature burning infiltration glass.These three mode all extends the service life of electrode, but still exist one common
Problem, is i.e. weak to the chemical attack of disinfectant and soda acid, long period of soaking in the water containing these materials, easy fouling, need to determine
Phase cleans.Therefore, it is necessary to existing atomizing piece is made improvement.
Utility model content
In view of this, the purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that one can be acid, alkaline
The corrosion-resistant ultrasonic transducer atomizing piece of the medium-term and long-term work of environment, improves its service life.
In order to solve above-mentioned technical problem, this utility model uses following scheme to realize:
A kind of corrosion-resistant ultrasonic transducer atomizing piece, including piezoelectric ceramics matrix and be separately positioned on piezoelectric ceramics matrix
First electrode of both sides and the second electrode, the surface of described first electrode and the second electrode covers one layer of nano zircite protection
Layer.
Spraying coating process of the prior art is used to cover nano zirconia material spraying to the first electrode and the second electrode
Outer surface, after solidification can tight bond on electrode, form protective layer.Due to the character that nano zircite is good, it is formed
Protective layer in addition to the cavitation corrosion that can prevent electrode and electrolytic etching, moreover it is possible to make electrode long in acid, alkaline environment
Phase works, and substantially increases the service life of ultrasonic atomizatio sheet, and nano zircite protective layer can ensure ultrasonic atomizatio
Can accomplish enough thin on the premise of effect is interference-free, thus reduce cost.Described electrode can be silver electrode, copper electricity
Pole and other electrode customary in the art.
The thickness of nano zircite is not the thickest more good or more Bao Yuehao, and thickness is less than time to a certain degree, and it easily exists
Under the effect of cavitation corrosion, electrolytic etching and chemical attack, premature aging occurs, then cause rupturing and come off, thus can not be preferable
Electrode is played a very good protection；Thickness, higher than time to a certain degree, can affect atomizing effect, and increase and produce into
This.Owing to the electrode property of multiple material is different, to this end, inventor has done substantial amounts of test, electrode of different nature is entered
Row test, have selected suitably sized parameter interval.The thickness of nano zircite protective layer described in nano zircite is 5 ~ 30 μm.
Preferably, the thickness of described nano zircite protective layer is 10 ~ 25 μm.It is further preferred that described nano zircite protective layer
Thickness be 15 ~ 20 μm.
The area of described first electrode is more than the area of the second electrode.First electrode surface needs to use other connected modes to draw
Enter on the second electrode surface, form plane with the second electrode surface, it is to avoid solid occurs the when of welding lead.
Further, described piezoelectric ceramics matrix is ring-shaped piezo ceramic matrix, described first electrode, the second electrode and
The nano zircite protective layer part corresponding with ring-shaped piezo ceramic matrix annular hollow portion is provided with multiple atomization through hole.Logical
Cross the setting of atomization through hole so that atomization quantity is greatly increased.
Described first electrode, the second electrode and nano zircite protective layer are relative to piezoelectric ceramics matrix annular hollow portion
Position indent.First electrode and the position of the second electrode indent namely be provided with the position of atomization through hole, therefore two electrodes
Curved of through hole is relative, forms cavity volume between the first electrode and the second electrode, passes through the water smoke of one of them electrode in dissipating
Shape enters in cavity volume, from the atomization through hole of another electrode out, can improve atomizing effect.
The funnel-shaped hole that described atomization through hole is conical through-hole and cylindrical hole is combined into, described funnel-shaped hole
In the first electrode and the second electrode, there is consistent direction.Consistent direction described here is explained as follows: one of them electrode
Upper formation funnel-shaped hole, the reference direction of setting conical through-hole now, then the taper of the funnel-shaped hole on another electrode
Through hole has the direction consistent with reference direction.The setting of conical through-hole is easy to contribute to water entrance through hole and is completed atomization, and justifies
The setting of cylindricality through hole increases nebulisation time, helps so that atomizing particle is more uniform, improves atomizing effect.
Compared with prior art, this utility model has the advantages that this utility model uses nano zircite spray
Being coated in electrode surface and form protective layer, this layer of protective layer makes electrode can work for a long time in disinfectant, acidity, alkaline environment
And do not corroded, substantially increase the service life of ultrasonic atomizatio sheet.
