The microwave device provides a microwave electric field for the accelerating tube through the waveguide tube, and at the same time, the electron gun makes the electrons gain energy through the accelerating tube. Finally, the equipment irradiates the medicine with a high-energy electron beam through a vacuum pump and a scanning magnet, thereby achieving the purpose of sterilization and disinfection. During the operation of the equipment, the first water pump in the water storage tank guides water into the first heat-conducting frame through the first water pipe and the second water pipe. In this process, the water will extract the heat from the surface of the pulse regulator, and the first heat dissipation metal block on the surface of the first heat-conducting frame will assist in the dissipation of heat in the water. After the water in the first heat-conducting frame is full, the water enters the first cold row through the third water pipe and the fourth water pipe.

At the same time, the second cooling fan cools the second cooling metal block on the second cold row, so that the water heated by the microwave device is cooled. At the same time, the water enters the third heat-conducting frame through the seventh water pipe, thereby taking away the heat from the surface of the focusing coil. At the same time, the water passes through the eighth water pipe and then into the third cold row. At the same time, the third cooling fan cools the second cooling metal block on the third cold row, so that the water heated by the focusing coil is cooled. At the same time, the water enters the fourth heat-conducting frame through the ninth water pipe, thereby reducing the temperature of the accelerating tube surface. Finally, the water flows back into the water storage tank through the tenth water pipe. At the same time, the fourth cooling fan in the groove on the water storage tank cools the water storage tank body, so that the water returning into the water storage tank is cooled again, thereby completing the entire water cooling cycle, thereby reducing the temperature of each major component of the equipment, thereby ensuring the normal operation of the equipment and facilitating the extension of the service life of the equipment.
