Description
[technical field] the utility model is a kind of ultrasonic atomization transducing sheet outermost layer contact-type electrode that is used for, and is a kind of sandwich high temperature sintering type conductor electrode that can thoroughly avoid crackle to produce specifically.
[background technology] ultrasonic atomizatio transducing sheet is the class-1 piezoelectric energy transducer that is widely used in atomizing humidifying performance, a kind of branched structure of this device is the method that adopts pressing block type contact conduction, briquetting by a plating nickel on surface utilizes the mode of threaded engagement to compress the negative pole of transducer, in order to guarantee transducer energy operate as normal, the cathode conductor electrode of transducer need satisfy following requirement: at first, the resistivity of the surfacing of cathode conductor electrode should be as far as possible little, guarantees that transducer has lower impedance level in working order down; Secondly, will inevitably produce the ultrasonic cavitation corrosion, thereby cathode conductor electrode and water need be isolated if the cathode conductor electrode directly contacts with water; Moreover the transducer negative pole is that the mode that adopts threaded engagement to compress contacts, and touches the waveform variation that causes for fear of virtual connection, the zone that contacts conduction is higher than has certain altitude.
[summary of the invention] the purpose of this utility model is: a kind of sandwich high temperature sintering type conductor electrode that can thoroughly avoid crackle to produce is provided, and the condition in order to the cathode conductor electrode needs that satisfy transducer guarantees that transducer can reliably working.
For solving its technical problem; the technical solution adopted in the utility model is: this electrode is made up of ceramic body and electrode; its feature is: on two surfaces up and down of the round sheet ceramic body after ground and cleaned oven dry; respectively be coated with one deck diameter argent electrode layer identical with flaky pottery body diameter; be coated with the vitreum protective layer that diameter is slightly less than argent electrode layer diameter in last argent electrode layer surface; on the part surface of the end face of this vitreum protective layer and argent electrode layer, be coated with the vitreum transition zone of slightly larger in diameter, on the residual surface of this vitreum transition zone radial end face and argent electrode layer, be coated with the conductor paste layer that drying becomes with high temperature sintering in the vitreum protective layer.The argent electrode layer of wherein said round sheet surface of ceramic body and described vitreum protective layer are concentric circles, its diameter the former greater than latter 100-500um; The thickness of described argent electrode is 1-5um, and every layer of Vitrea thickness is 5-10um.
The utility model has the advantages that: 1, because of the electrode layer center is covered by the vitreum protective layer, the end face of vitreum protective layer has the vitreum transition zone to cover again, the end face of vitreum transition zone has the conductor paste layer to cover again, and vitreum protective layer and vitreum transition zone and conductor paste layer be three layers disposable through the high temperature sintering moulding, the conductor paste layer has good electrical conductivity and sealing behind high temperature sintering, therefore the resistivity of kind electrode is little, good airproof performance, can not produce ultrasonic cavitation corruption and virtual connection and touch the waveform variation that causes, work that can be reliable and stable, and the zone of satisfied contact conduction is higher than the requirement with certain altitude; 2, the cost of material is low because of this electrode, and the available machines used high-speed production, so kind electrode is cheap, and the very strong market competitiveness is arranged, and is a kind of desirable ultrasonic atomization transducing sheet outermost layer contact-type electrode.
