Almost any type of combustion process generates smoke gas with certain toxicity, the toxicity comes not only from carbon monoxide gas, but also from various plastic components in building materials, the toxic gas generated immediately after a fire outbreak can cause smoke poisoning, for example, PVC releases hydrochloric acid gas when burning, polyamide releases ammonia gas when burning, and some plastics release hydrogen cyanide gas which can prevent cells from absorbing oxygen to cause people to breath when burning, therefore, the smoke must be discharged out of the room before diffusing in the building, smoke discharge is particularly important for corridors and staircases, because the areas are used as escape and rescue passages, when the temperature exceeds 500 ℃, steel structural parts lose bearing capacity, the whole building collapses and cannot be rescued, and the staircases lose the function of the rescue passages, therefore, in case of fire, the cooling of the corridor is particularly important, and a fire sprinkler is generally adopted.
The existing fire sprinkler mainly adopts a glass tube, a fusible alloy or electric induction control as a trigger mechanism of the fire sprinkler, and the existing fire sprinkler has certain defects, such as: when the temperature of the glass tube bursting triggering type spraying device exceeds minus 5 ℃, the glass tube bursting triggering type spraying device can be frozen, water can be frozen, and the glass tube is burst by the water in the pipeline, so that the glass tube is self-exploded; the fusible alloy melting triggering type spray device can be melted only when the room temperature reaches a certain height, has time delay, and cannot be quickly triggered and inducted insensitively; the electric induction control mainly adopts a temperature sensor or a smoke alarm, is sensitive in induction, but needs conditions such as an external independent power supply, communication of a power supply passage and the like, is limited, is easy to malfunction in case of complex fire emergency and has poor stability; in addition, most traditional fire sprinkler devices of mechanical type are mainly disposable structure mostly, can't carry out used repeatedly, touch or can't carry out the reutilization after the device is out of order in the alarm mistake, it is great to consume the cost, has certain limitation.
