Ultrasonic probe

Abstract

The invention discloses an ultrasonic probe. The ultrasonic probe comprises a grounded copper foil, a power supply device, a protection film, a piezoelectric wafer, an absorption block, a metal housing, a lug plate, a conductive screw, a needle, a receptor, a fixed ring, an ultrasonic divergence device, a connecting block, a connecting wire, an insulated mast and an exhalant, wherein the groundedcopper foil is fixedly connected to and mounted at a left side end opening of the power supply device and fixedly connected with the ultrasonic divergence device through the power supply device; the power supply device is arranged at the connecting part of the fixed ring and the grounded copper foil; the protection film wraps the periphery of the piezoelectric wafer; the exhalant is arranged in the receptor and connected with the needle. According to the ultrasonic probe, as the power supply device is arranged, the ultrasonic probe can be effectively controlled to work; meanwhile, the insulated mast can prevent electric energy from getting loss during electricity transport of the conductive screw; the working accuracy and the safety of the ultrasonic probe are improved; the ultrasonic probe is simple in structure and convenient to maintain.

Problems solved by technology

[0003] In the process of ultrasonic detection, the emission and reception of ultrasonic waves are realized by the probe. The performance of the probe directly affects the characteristics of the ultrasonic wave and affects the detection performance of the ultrasonic wave. The probe used in the ultrasonic detection is to use the piezoelectric effect of the material to realize the electric energy. 1. Transducer for acoustic energy conversion. The key component in the probe is the wafer. The wafer is a single crystal or polycrystalline sheet with a piezoelectric effect. Its function is to convert electrical energy and acoustic energy into each other. The receiving signal of the probe is not very good, and the outer surface is easily corroded, which leads to the deviation of the test results. Therefore, it is necessary to create a new type of ultrasonic probe to solve these problems
