Ultrasonic tool head is an important component of ultrasonic equipment. Its function is to transfer ultrasonic vibration energy to the target. Ultrasonic tool head shape, generally for cylinder, cone and cuboid shape, its working surface basically is at the top of the end face, considering the actual installation, head of the working face of such tools generally small, so the radiation ability is relatively concentrated, can better application in ultrasonic welding, cutting and ultrasonic traditional application direction. However, with the continuous progress of science and technology, ultrasonic is not limited to the traditional application, its application in liquid and gas has been more and more widely, such as emulsification, separation, homogenization, extraction, defoaming, cleaning, liquid atomization and accelerated chemical reaction in the application.
