When the fire of the prior building occurs, the fire of individual units in the building is extinguished, the building is provided with more perfect fire extinguishing facilities for fire fighters to use, and the layering and separating structures in the building also play a role in preventing and limiting the spread of fire, so that the problem is not too large as long as the fire is found and extinguished in time.

However, the combustion of individual units originally in the interior of a building tends to spread to the outer wall of the building through windows, balcony doorways, and to spread rapidly upward and leftward and rightward by means of strong wind. These spread-out fires, in turn, pass through more cell windows, balcony doorways, and into the building interior, thereby creating a greater range of combustion. Therefore, the fire extinguishing work for the outer wall of the building is not only slow.

In spite of the current fire extinguishing means for the outer wall of the building, a professional fire truck is used to spray fire extinguishing liquid (either water or foam) from the vicinity of the burning point of the outer wall of the building. However, as the height of buildings is increased, the upward spraying capability of the fire engine is more and more incontinent, and even no more!

In the fire extinguishing system of the external wall of the building in the prior art, for example: patent high-rise building outer wall fire extinguishing systems 201120067823.8, it is through surrounding the shower on the building outer wall body to use high-pressure water source to supply water to the shower, thereby put out a fire to the building outer wall, this design needs to use high-pressure water source. The patent relates to a water curtain fire extinguishing system 2016210862733 for the outer wall of a high-rise building, which also uses a high-pressure water source and directly depends on a water pump to carry out high-pressure pipeline conveying. Because a certain amount of water sources are not reserved, and the system is in a full-water state all the year round, the whole water conveying pipeline is in a high-pressure state all the year round, and the daily maintenance requirement is very high. In the aspect of fire extinguishing, the water spray pipes are arranged on the outer wall surface of a building in a surrounding mode, water spray wall holes are uniformly distributed on the inner sides of the water spray pipes, and the requirement on water quality is high (nozzles are prevented from being blocked). When the fire on the outer wall is great and is close to the spray head, the spray head is possibly burnt out, so that the system fails.

Patent high-rise building fire extinguishing system 2014204327732, in the aspect of water source supply, though set up the water storage box on the roof, the upper end opening part is provided with one deck water strainer, accepts the rainwater and is used for putting out a fire, reduces the use amount of groundwater, saves the cost of putting out a fire. However, due to the existing environmental pollution, rainwater is acidic, and impurities such as dust exist, so that the rainwater is easy to corrode, deposit and block for a long time, and the daily maintenance requirement is high.
