Abstract
The utility model discloses an ultrasonic cleaning transducer, comprising a front-end emitter, a rear-end mass block, two hollow piezoelectric ceramic wafers arranged between the front-end emitter and the rear-end mass block, an insulation sleeve, and bolts which fix all the components on the front-end emitter. A hollow electrode film is arranged between the two piezoelectric ceramic wafers; two homopolar hollow electrode films are respectively arranged on the axially external end faces of the two piezoelectric ceramic wafers; hollow insulation spacers are arranged between the two homopolar hollow electrode films and the front-end emitter, and between the two homopolar hollow electrode films and the axially internal end face of the rear-end mass block. The radially external end parts of the two homopolar hollow electrode films are connected with each other in a U shape. As the hollow insulation spacers are arranged between the two homopolar hollow electrode films and the front-end emitter, and between the two homopolar hollow electrode films and the axially internal end face of the rear-end mass block, the ultrasonic cleaning transducer of the utility model can effectively prevent high-frequency voltage being directly added to a metal cleaning tank so as to avoid current leakage and enable safe operation.
Description
Technical field
The utility model relates to a kind of cleaning ultrasonic transducer.
Background technology
At present, employed cleaning ultrasonic transducer is to be assembled successively by piezoelectric ceramic wafer, front end aluminium alloy emitting head, rear end metal quality piece, electrode slice, insulating sleeve, the hexagon socket head cap screw of drawing from the piezoelectric ceramic wafer axial end.Its high frequency voltage that produces tens KHzs by a high-frequency signal power supply is parallel on two electrodes of transducer, resonate with the intrinsic frequency of transducer, and the vibration wave that produces is delivered to aqueous medium in the groove by bottom of rinse bath, and make aqueous medium produce cavitation, thereby play the effect that ultrasonic wave cleans.Wash vegetables, fruit, jewellery, glasses, wrist-watch etc. as ultrasonic wave.But tens volts even the high frequency voltage of going up hectovolt directly are added on the metal rinse bath, and the electric leakage accident easily takes place, and use dangerous.
Summary of the invention
The technical problems to be solved in the utility model provides the cleaning ultrasonic transducer that a kind of leaky safe in utilization, no takes place.
For solving the problems of the technologies described above, the utility model comprises the front end emission head, the rear end mass, place the hollow piezoelectric ceramic wafer between front end emission head and the rear end mass, insulating sleeve, above-mentioned parts are fixed to the bolt of front end emission head, its design feature is that described piezoelectric ceramic wafer is two, between two piezoelectric ceramic wafers, be provided with the coreless armature sheet, on two piezoelectric ceramic wafer axial outer end faces, be respectively equipped with homopolarity coreless armature sheet, be placed with hollow insulation spacer between two homopolarity coreless armature sheets and front end emission head and the rear end mass axial inner ends face.
As to improvement of the present utility model, described two homopolarity coreless armature sheet radial outer end portions are the U type and connect.
After adopting said structure, owing between two homopolarity coreless armature sheets and front end emission head and rear end mass axial inner ends face, be placed with hollow insulation spacer, can prevent effectively that high frequency voltage directly is added on the metal rinse bath, avoid occurring the electric leakage accident, safe in utilization.And two homopolarity coreless armature sheet radial outer end portions are the U type and connect, and assembles conveniently, and connection is more safe and reliable between electrode.
