technical background

Every year, many forest fires occur all over the world, threatening people's lives and property safety, causing environmental pollution, and even hindering the sustainable development of society. The occurrence of large-scale grassland forest fires has made relevant departments attach great importance to fire prevention and fire fighting, as well as the research and development of fire extinguishing equipment. Portable wind fire extinguishers have been widely popularized due to their advantages of environmental protection and energy saving. However, portable wind fire extinguishers require a lot of physical strength and endurance for firefighters, and the fire extinguishing range is limited, which will lead to low fire extinguishing efficiency. The wind fire extinguisher has been in a portable state after 30 years of development and needs to be further explored.
