[0002] A pressure cooker in the laboratory is a device that can generate a high-pressure, high-temperature environment. It can process material samples under high temperature and high pressure for subsequent testing and analysis. Laboratory pressure cookers are mainly used for sterilization, sample processing, accelerating chemical reactions, and other special experimental processes. They are an indispensable piece of equipment in the laboratory.
[0003] In existing technologies, after a material sample is placed in a pressure cooker, the pressure cooker will release gas during operation. To prevent the gas valve from popping out and injuring staff during pressurization, the pressure cooker is usually placed in a corner of the laboratory. However, placing and using the pressure cooker away from the main work area of the laboratory makes it inconvenient for staff to work in a timely manner, affecting their work efficiency, and the safety hazard of the gas valve popping out still exists. Therefore, we propose a new type of pressure cooker protective cover. Utility Model Content
