Abstract
The utility model relates to a strong-anti-corrosion ultrasonic transducer, comprising a piezoelectric ceramic base piece 1, electrodes 3, 4, and conducting wires 31, 41, wherein, a layer of a resin or glue anti-corrosion layer 5 is directly covered on the electrode 3 on one face of a contact medium by spray coating or smearing; the resin or the glue anti-corrosion layer 5 can select corresponding anti-corrosion materials and can adopt the direct covering mode according to the corrosiveness of the contact medium. Thus, the anti-corrosion ability can be increased, the resin or the glue anti-corrosion layer is not easy to drop off, and simultaneously, the ultrasonic transmission performance can be increased, and the high-efficiency transduction of energy can be realized. The direct covering mode is an ideal anti-corrosion method.
Description
The utility model relates to the ultrasonic device in the operation, particularly the ultrasonic transducer used of the atomization of liquid.
Ultrasonic atomization transducer of the prior art, on the electrode of the one side of contact medium, it is anticorrosion mostly to adopt surface stickup stainless steel substrates to carry out, owing between stainless steel substrates and the electrode bonded adhesives is arranged, the sound translative performance of transducer is reduced greatly, because the restriction of stainless antiseptic power, the scope of application of transducer is dwindled greatly, because directly transmission and produce heat on glue-line of ultrasonic energy reduces bonding force greatly, stainless steel substrates comes off easily, thus the antisepsis of losing.
The purpose of this utility model provides a kind of ultrasonic energy of giving full play to, and anticorrosion scope is wide, the strong anticorrosion ultrasonic transducer of anticorrosive coat difficult drop-off.
The utility model is realized by implementing following technical scheme: make a kind of strong anticorrosion ultrasonic transducer, comprise the piezoelectric ceramics substrate, two electrodes are contained in its two sides respectively, have two leads to draw from electrode and electrode respectively.On the electrode of contact medium one side, adopt spray attached or be coated with the anticorrosive coat of resin or glue class.It is characterized in that: described anticorrosive coat covers entire electrode.Its feature also is: described anticorrosive coat also can cover the whole ultrasonic wave transducer.Its feature is again: described lead is below anticorrosive coat.
Further describe the most preferred embodiment of the utility model below in conjunction with accompanying drawing.
Fig. 1 is that the master of the strong anticorrosion ultrasonic transducer of the utility model looks, cutaway view.
Fig. 2 is the vertical view of the strong anticorrosion ultrasonic transducer of the utility model.
Can find out that from Fig. 1, Fig. 2 a kind of strong anticorrosion ultrasonic transducer comprises piezoelectric ceramics substrate 1, electrode 3 and electrode 4 are contained in its two sides respectively, have two leads 31 and 41 to draw from electrode 3 and electrode 4 respectively.On an electrode 3 of contact medium, adopt spray attached or be coated with the anticorrosive coat 5 of resin or glue class.Because the existence of anticorrosive coat 5 is arranged, electrode 3 can not directly be contacted with medium, guard electrode 3 effectively, and prolong service life.Anticorrosive coat 5 can be selected corresponding anti-corrosion material targetedly and adopt the mode that directly covers according to the corrosivity of want contact medium, can avoid stainless steel corrosion-resistant limitation like this and improve antiseptic power, and be not easy to come off, can realize the efficient conversion of energy owing to not existing intermediate gelatine layer to improve hyperacoustic transmission performance effectively simultaneously.
Can find out that from Fig. 1, Fig. 2 described anticorrosive coat 5 covers entire electrode 3.Described anticorrosive coat 5 also can cover the whole ultrasonic wave transducer.Described lead 31 is below anticorrosive coat 5.Anticorrosive coat 5 can a guard electrode 3, also can protect whole energy transducer, and lead 31 can not be subjected to the infringement of Korrosionsmedium below anticorrosive coat.
The utility model can be given full play to ultrasonic energy owing to adopted above-mentioned technical scheme, and anticorrosion scope is wide, and the anticorrosive coat difficult drop-off, is desirable anti-corrosion method.
