Detailed Description

The present invention will be described with reference to specific embodiments.

As shown in fig. 1-2, an ultrasonic wave power synthesis transducer, including syntonizer 1, double-screw bolt 2, potsherd 3 and copper pole piece 4, syntonizer 1 is the circular truncated cone form, and its main aspects are located the top, and the even vertical double-screw bolt 2 that is connected with in 1 main surfaces of syntonizer, potsherd 3 are the discoid of central through-hole, and potsherd 3 superpose is installed between 2 bottoms of double-screw bolt and 1 main terminal surface of syntonizer, and copper pole piece 4 is located potsherd 3 and syntonizer 1, between potsherd 3 and potsherd 3, 2 upper portions of double-screw bolt are equipped with gland 5, and gland 5 is one end open-ended cylinder cell body, and gland 5 lock is in 3 upper ends of potsherd, and screws up through double-screw bolt 2, parallelly connected electric.

The ultrasonic generator is characterized in that at least two groups of studs 2, corresponding ceramic plates 3 and copper pole pieces 4 are arranged on the resonator 1, and the studs 2, the corresponding ceramic plates 3 and the corresponding copper pole pieces 4 are assembled and installed on the same resonator 1, so that the ultrasonic power can be improved by multiple times, the working frequency points are consistent, and the stability is high.

3 quantity of potsherd on the double-screw bolt 2 are 2 ~ 4 pieces, according to the experiment test result, the amplified power of different numbers of pieces is different, 1 during the monolithic, 1.8 during the biplate, 2.1 during 4 pieces, 2.6 during 6 pieces, 3 quantity of superimposed potsherd and the power of increase are not proportional, 3 power increase of potsherd more than 4 is not obvious, consequently 3 quantity of superimposed potsherd are when 2 ~ 4 pieces, the power amplification effect is better, the transducer structure is succinct, reduce manufacturing cost.
