Abstract
The utility model relates to an energy transducer with a long-life piezoelectric ceramic wafer. The utility model belongs to ultrasound energy transducing equipment. The utility model uses a protection layer to separate the electrode surface of a piezoelectric wafer from the water, the active corrosion of water to electrodes is prevented during the work of the wafer, and therefore, the service life of the wafer is lengthened. The utility model is used on a medicine atomizer, and the service life of the medicine atomizer is lengthened by more than eight times.
Description
The invention belongs to ultrasonic transduction equipment
At present, the piezoelectric ceramic wafer energy transducer that uses in the various medical ultrasonic atomizers, its structure is to be constituted electrode on the two sides of piezoelectric crystal plate by silver, then its level is installed in the bottom of atomizing tank, and the electrode of its one side up all is directly to contact with the liquid of water and so on.Come off because the effect of electricity and chemistry, its electrode are very easily corroded, the life-span is very short.
The electrode and the water that the objective of the invention is to contact with water when with a protective layer wafer being worked one side separate, and have stopped the corrosion of water to electrode, thereby have prolonged the useful life of wafer greatly.
Penetrate to the width of cloth of medium for the efficient and the energy that do not influence the performance of wafer, particularly power conversion, the present invention selects for use the mylar about thickness 0.5mm to make diaphragm.Between diaphragm and electrode surface with dielectric fillings such as epoxy resin or absolute ethyl alcohols.Certainly, select for use other insulating material to make diaphragm.Adopt other filler, or with other spraying way diaphragm is attached on the chip electrode surface and constitutes protective layer, also can play same purpose.
This product use effect on the medicinal atomized therapeutic equipment of WH-1 that Nanchang radio factory produces is obvious, and the person compares with originally not adopting the protective layer, and the life-span prolongs more than the octuple.
In the Figure of description:
1 is mylar.
2 is dielectrics such as epoxy resin or absolute ethyl alcohol.
3 is electrode
4 is piezoelectric crystal plate.
Claims (1)
- A kind of piezoelectric ceramic wafer energy transducer that is constituted electrode on piezoceramics crystal sheet two sides by silver is characterized in that topped layer protective layer on the electrode of the one side that contacts with water when its work.Mylar 1 and the dielectrics such as epoxy resin or absolute ethyl alcohol 2 of this protective layer about by 0.5mm constitute.
