Summary of the invention

The invention utilizes the liquid as the transmission medium of the ultrasonic wave and the vibration wave of the tray connecting tool head, and realizes the ultrasonic wave and the vibration. The wave transducer tray integral fixing member and the tool head (container, etc.) are simply connected or separated without gaps, and the connecting liquid acts as a flexible horn to increase the amplitude, thereby improving the transmission efficiency of ultrasonic waves and vibration waves. When the liquid medium is used to connect the tool head for energy transfer, the connecting liquid is a flexible horn, which not only reduces the cost of the device, but also ensures the working efficiency of ultrasonic wave and vibration wave transmission. The device uses liquid cooling to solve the problem of overheating in the operation of ultrasonic and vibration wave vibrators. The transducer and the connecting liquid tray of the device are bolted to the integral fixing member, and are divided into a front connecting liquid tray, an intermediate piezoelectric piece and a rear end inertia weight, which are integrally fixed by bolts and adhesives. In order to reduce the attenuation in ultrasonic transmission, ultrasonic waves and vibration waves can be transmitted more efficiently. '

 The ultrasonic transducer can be composed of single or multiple transducing heads, and the selection of parameters such as the power and frequency of the transducing head depends on the functional configuration requirements.

 Water or other viscous liquid can be used to transfer the liquid to the tool head, and the liquid with higher viscosity is better. When used industrially or commercially, water or viscous liquid can be used as the transfer medium for connecting the tool head as needed. It is convenient to use water as the connecting tool head to transfer the medium in the family life.

 Ultrasonic waves and vibration waves are converted into electrical energy by electrical energy. During the conversion process, the impedance cannot be ideally matched. At this time, the transducer head converts the remaining mechanical energy into heat energy, which may burn the transducer head when there is a serious mismatch. Therefore, the transducing head cooling container is provided, and the heat of the transducing head is realized by cooling the liquid in the container, thereby ensuring safe and continuous operation of the device <=

 By using the energy transmission efficiency of the "ultrasonic, vibration wave transducer and liquid connection tool head to transfer energy" and the energy transmission efficiency of the conventional product, the test results show that the energy transfer efficiency is substantially equal and no attenuation occurs. detailed description
