However, even though almost all areas such as office buildings, warehouses and public places are provided with perfect fire-fighting spraying systems, the condition that the fire is aggravated because the fire cannot be relieved and rescued in time happens frequently, and therefore serious casualties and property loss are easily caused.
In addition, when the fire suddenly drops, a distressed person or a manager can give an alarm in time and remind people of rapidly withdrawing, and the initial fire is always processed in a relatively large passive mode, so that the fire cannot be relieved and rescued at the first time. Because, when the fire breaks out and people cannot put out a fire, the fire rapidly spreads, and the general fire temperature is as high as about 1000 ℃, and the temperature near the fire reaches hundreds of degrees. At this time, only the fire sprinkler head can extinguish or relieve a large area of fire. However, the fire sprinkler head has a certain starting temperature, and a general fire sprinkler head is arranged at a high position as much as possible, so that a large radiation area can be provided, and this often causes that when the fire sprinkler head reaches the starting temperature and is started, the temperature of flames nearby is maintained at a high state, and high-temperature radiation generated by the flames at the moment can blame objects beyond several meters, so that the starting of the fire sprinkler head cannot catch up with the spread of fire, and thus a large disaster is easily caused.
