One side of the air collecting hood 61 is fixedly connected with two air supply pipes 62, and one end of the air supply pipe 62 is installed on the air inlet 67.

[0024] In the present embodiment: when the motor 3 drives the fan blade 2 to rotate, the air on the inner wall of the civil air defense project can be sucked, and the gas then enters the air collecting hood 61, and is input to the air inlet 67 of the sealing hood 65 through the air collecting hood 61 and the air supply pipe 62. The gas will drive the turbofan 66 and the fan blade 2 5 to rotate, and then the gas is discharged through the air outlet 68, so that the discharged gas can be fully utilized.

[0025] Specifically, a filter screen 63 is installed on the inner wall of the air collecting hood 61, and the filter screen 63 is arranged in a circular shape.

[0026] In this embodiment, when the gas enters the gas collecting hood 61 , the filter 63 can intercept and filter the impurities.

[0027] Specifically, the air supply pipe 62 includes a large tube body 621, which is connected to the air collecting hood 61. A small tube body 622 is installed at one end of the large tube body 621, and the small tube body 622 is connected to the air inlet 67. After the gas is discharged into the small tube body 622 through the large tube body 621, the gas pressure can be increased, thereby better driving the turbofan 66.

[0033] Working principle: When the equipment is in use, the motor 3 can drive the fan blade 2 to rotate, suck air from the civil air defense project room, and ventilate it. By setting the transmission device 6, when the motor 3 cooperates with the fan blade 2 to suck, the gas will enter the gas collecting hood 61, and the filter 63 can filter impurities. The filtered gas is discharged into the air inlet 67 through the air supply pipe 62. Since the gas can increase the gas pressure after passing through the large tube body 621 and discharged into the small tube body 622, the gas will then drive the turbofan 66 and the fan blade 2 5 to rotate, and cooperate with the fan blade 2 to exhaust and ventilate at the same time. When cleaning, the positioning rod 64 can be 7 is pulled out from the circular hole on the surface of the cover body 644, and the push rod 645 and the rotating shaft 643 are rotated.

This can effectively reduce the existing civil air defense projects. Usually, most of them will install multiple axial flow fans for ventilation. Each axial flow fan is powered and rotated separately, which causes a lot of energy consumption when working at the same time, thereby improving the overall energy saving effect of the equipment.
