Latest Patents

Hui Yu's latest patents include a foam producing method, a fire extinguishing method, and an appliance for foam extinguishing. The foam production method involves mixing liquid nitrogen with a foaming material to generate foam. This process produces gas in situ from the liquid nitrogen. The high ratio of gas produced to the volume of liquid nitrogen allows for a large gas supply flow, which is essential for generating substantial foam flow. This innovation enables the use of a compact liquid nitrogen storage device instead of bulky air supply devices, such as high-pressure gas cylinders and air compressors. Additionally, the nitrogen gas released after the foam blast helps inhibit combustion on the surface of burning materials, thereby accelerating fire extinguishing.
