The intake pipe 110 is used to suck the air outside the pigsty into the pigsty, and the exhaust pipe 120 discharges the air inside the pigsty to the outside of the shed. A fan 130 for extracting outdoor air into the pigsty is provided on the intake pipe 110. During the operation of the fan 130, negative pressure is generated, thereby driving the air inside and outside the pigsty to form an air flow. A filter screen 170 is provided at the head end of the intake pipe 110. The setting of the filter screen 170 can prevent some animals or insect bodies with larger sizes from entering the pigsty. A plurality of fly-killing components 140 are arranged at intervals along the axial direction of the intake pipe 110 in the middle of the intake pipe 110. The fly-killing components 140 are used to kill flies and other mosquitoes that enter the intake pipe 110 through the filter screen 170. A plurality of collection boxes 150 are connected to the bottom of the intake pipe 110. The collection boxes 150 are used to collect the killed mosquito bodies together. The plurality of collection boxes 150 are respectively located directly below the plurality of fly-killing components 140. When the mosquitoes are killed, their bodies will fall into the collection boxes 150 by their own gravity. One end of the top of the collection box 150 is connected to the intake pipe 110, and one end of the bottom of the collection box 150 is connected with a cover 151 for sealing the collection box 150. After the cover 151 is opened, the mosquito bodies can be discharged from the cover 151. The fly-killing component 140 includes an electric fly swatter 141. The electric fly swatter 141 can adopt the prior art. The shape of the electric fly swatter 141 can be circular so that it can better fit the intake pipe 110, thereby increasing its working surface. One end of the electric fly swatter 141 is connected with a lap plate 142 through a fixing member. The electric fly swatter 141 is detachably fixed on the lap plate 142 through the fixing member. The shape of the lap plate 142 can be designed according to the external contour of the intake pipe 110 so that after the lap plate 142 is installed on the intake pipe 110, the overall external part of the intake pipe 110 and the lap plate 142 forms a smooth surface. An installation hole 111 is opened on one side of the top of the intake pipe 110. During the installation process, the whole electric fly swatter 141 can be inserted into the intake pipe 110 from the installation hole 111. An installation groove 112 corresponding to the lap plate 142 is arranged on the outer periphery of the installation hole 111. The lap plate 142 is lapped on the top of the installation groove 112. A sealing ring 143 is jointly arranged between the lap plate 142 and the installation groove 112. A plurality of fixing bolts 113 are jointly connected between the lap plate 142 and the installation groove 112. During the installation process, the lap plate 142 and the electric fly swatter 141 are connected into one body through the fixing member, and then the electric fly swatter 141 is inserted into the intake pipe 110 along the installation hole 111. The lap plate 142 will be lapped above the installation groove 112. Tightening the fixing bolts 113 can install the lap plate 142 and the intake pipe 110 into one body.
