[0038] The smoke exhaust pipe 11 is used to guide the smoke, and the exhaust fan 12 is used to form a negative pressure in the room through the smoke exhaust pipe 11;

[0039] The filter screen 25 is a ∠-shaped structure, and both ends of the filter screen 25 are in contact with the inner wall of the smoke exhaust pipe 11 respectively;

[0040] The filter 25 can limit the particles in the smoke to the inner side of the filter 25, and the sprayed cold water can be sprayed downward from the upper end of the filter 25;

[0041] The filter screen 25 is located inside the upper end of the water collecting box 26, and the width of the water collecting box 26 is greater than the width of the sprinkler head 24;

[0042] The spray head 24 sprays cold water downward through the filter screen 25 and the second hollow groove 22 into the water collecting box 26, and does not enter the exhaust pipe 11;

[0043] Working principle: When the exhaust fan 12 forms a negative pressure in the room through the smoke exhaust pipe 11, the smoke enters from one end of the smoke exhaust pipe 11 and is discharged from the other end. At this time, the cold water tank 23 and the spray head 24 are turned on, and the cold water in the cold water tank 23 is sprayed downward through the spray head 24. The cold water contacts the smoke and reduces the temperature of the smoke. The smoke flows downward through the filter 25 to the inside of the water collecting tank 26.

The cold water sprayed by the spray head 24 sprays downward on the top of the filter 25, so that the spray head 24 will not be blocked by the particles. The particles are sprayed to the position above the bottom of the filter 25, which can protect the exhaust fan 12.

[0048] The first through hole 32 and the second through hole 35 are opened relative to the movable column 34, and the movable column 34 is a T-shaped structure;

[0049] When the movable column 34 passes through the second through hole 35 and enters the first through hole 32 , the movable column 34 fixes the fixed plate 31 ;

[0050] Working principle: When the filter 25 needs to be installed, an outward force is applied to the movable column 34 to move the movable column 34 outward. The outward movement of the movable column 34 drives the telescopic spring 33 to stretch and generate elastic force, and then the filter 25 is placed inside the smoke exhaust pipe 11 through the fixed plate 31, and the fixed plate 31 is moved to correspond to the first through hole 32 and the second through hole 35.
