The invention discloses a fire-fighting fan capable of spraying water mist. The fire-fighting fan capable of spraying the water mist comprises a motor and a pump body. A protection shell is connectedto the outer portion of the motor in a sleeving mode, a radiating fin is arranged at the left end of the protection shell, an output shaft of the motor is connected with an impeller, two sides of theprotection shell are connected with a fixed rod, one end of the fixed rod is connected with a fan shell, an air inlet is formed in one end of the fan shell, an air outlet is formed in the other end ofthe fan shell, and a first protection net is arranged at the air inlet. A dust filter net is arranged between the first protection net and the motor, a second protection net is arranged at the air outlet of the fan shell, a double-layer guide cover is arranged at the air outlet end of the fan shell, an water inlet of the pump body is connected with water guide pipes, an water inlet of the double-layer guide cover is connected with the water guide pipes, a water cooling pipe is arranged between the water guide pipes, and valve bodies are arranged at one ends of the water guide pipes. The fire-fighting fan capable of spraying the water mist can effectively resist high-temperature thick smoke, and can rapidly spray the water mist and reduce the surrounding temperature.
Description
technical field [0001] The invention relates to the field of firefighting, in particular to a firefighting blower capable of spraying water mist. Background technique [0002] In high-rise buildings, underground buildings, tunnels, drying rooms and other places, it is often necessary to use fire-fighting fans, so that when a fire occurs, the fire-fighting fans can ventilate or cool the high-temperature gas through the fire-fighting fans, and discharge high-temperature smoke. For the existing As far as the fire-fighting fan is concerned, it is limited by the structural and design restrictions. When it works in a high-temperature environment for a long time, it is still easy to be damaged by high-temperature smoke erosion. The fan causes damage, which seriously affects the normal operation of the fire-fighting fan, and these greatly affect the performance and service life of the fire-fighting fan. [0003] For example, Chinese patent application number CN201620549846.5 disclo...
