[0003] With societal development, residential building fires are becoming increasingly common, often resulting in mass casualties. Preventing fires before they occur and extinguishing them efficiently and quickly in the event of a fire is a critical issue. However, in contemporary society, residents often prioritize theft prevention over fire prevention. Very few households own fire extinguishers, and their proper maintenance is a significant challenge. In the event of a fire, elderly people and children left at home often lack the skills to operate traditional fire extinguishers, let alone provide assistance in extinguishing a fire when no one is home. Therefore, addressing the urgent need to quickly extinguish fires in residential buildings and minimize casualties and property damage is a pressing problem.

[0004] Therefore, it is urgent to invent a small, low-cost, intelligent household automatic fire extinguishing device that can be operated 24 hours a day and has the ability to extinguish fires automatically, so as to improve the fire prevention and fire extinguishing technology of homes.
