On both sides of the environmentally friendly pigsty main body 1, air inlets are symmetrically arranged. Inside the environmentally friendly pigsty main body 1, a ventilation and purification component 3 is provided. The ventilation and purification component 3 includes: a purification component 31, symmetrically arranged on both sides of the environmentally friendly pigsty main body 1; a disinfection component 32, arranged inside the environmentally friendly pigsty main body 1. The purification component 31 includes: an air inlet pipe 311, fixedly sleeved inside the air inlet; a connection box 316, communicated and arranged at the bottom of the air inlet pipe 311. On the top and bottom inner walls of the air inlet pipe 311, chutes are respectively arranged. On one side of the air inlet pipe 311, a connection port is arranged, and the connection port is communicated with the chute. Inside the air inlet pipe 311, a filter layer 312 is fixedly installed. The air inlet pipe 311 is slidably connected with a high - level filter 313 through the chute. The high - level filter 313 is snap - connected with the air inlet pipe 311 through the connection port. On one side of the high - level filter 313, a connecting plate one 314 is fixedly installed. On the outer side of the connecting plate one 314, a handle one 315 is fixedly installed. On one side of the connection box 316, a movable port is arranged. The connection box 316 is movably connected with a storage drawer 317 through the movable port. On one side of the storage drawer 317, a connecting plate two 318 is fixedly installed. On the outer side of the connecting plate two 318, a handle two 319 is fixedly installed. On the top of the air inlet pipe 311, an electric guide rail 3111 is fixedly installed. On the outer wall of the electric guide rail 3111, a sliding seat 3112 is slidably connected.

Connecting shafts 324 are respectively fixedly installed on the front and back of the water outlet tank 325. The other ends of the connecting shafts 324 movably penetrate the inner wall of the environmental protection pigsty body 1 and extend to the outer wall of the environmental protection pigsty body 1, and are rotatably connected to the environmental protection pigsty body 1 through bearings. The output end of the motor 323 is connected to one end of one of the connecting shafts 324. Atomizing nozzles 326 are equidistantly communicated and arranged at the bottom of the water outlet tank 325. A water inlet pipe 328 is communicated at the top of the water storage tank 327. The input end of the water pump 329 is communicated with a water suction pipe 3211. The other end of the water suction pipe 3211 penetrates the top of the water storage tank 327 and extends into the water storage tank 327. The output end of the water pump 329 is communicated with a water outlet pipe 3212. The other end of the water outlet pipe 3212 movably penetrates the outer wall of the environmental protection pigsty body 1 and extends into the inner wall of the environmental protection pigsty body 1, and is communicated with the water outlet tank 325.

[0033] Furthermore, in the embodiment, the UV disinfection lamp 322 is turned on to perform UV disinfection on the air in the pigsty. Ultraviolet rays can destroy the nucleic acid structure of bacteria and viruses, making them lose their activity, thereby achieving the purpose of disinfection. The disinfectant is added into the water storage tank 327 through the water inlet pipe 328. The water pump 329 is started, and the water in the water storage tank 327 is pumped out through the water pump 329, and then conveyed to the water outlet tank 325 through the water outlet pipe 3212. The motor 323 is started to drive the connecting shaft 324 to rotate, so that the water outlet tank 325 rotates. The atomizing nozzles 326 equidistantly communicated at the bottom of the water outlet tank 325 atomize and spray the water, and the water mist fills the pigsty to disinfect the air and further disinfect and purify the inside of the environmental protection pigsty body 1.

[0034] In use, first start the exhaust fan 4. The outside air enters the air inlet pipe 311 through the air inlets on both sides of the environmental protection pigsty body 1. The filter layer 312 fixedly installed inside the air inlet pipe 311 first preliminarily filters the air, intercepting larger particulate dust, impurities, etc. in the air. As the air continuously enters, impurities will gradually accumulate on the filter layer 312. At this time, the electric guide rail 3111 starts, driving the sliding seat 3112 to slide on its outer wall. The L-shaped connecting rod 3113 on one side of the sliding seat 3112 and the brush strip 3114 inside it move accordingly. The brush strip 3114 contacts the filter layer 312 and can brush off the accumulated impurities on the filter layer 312 to maintain the filtering effect of the filter layer 312. The air that has been preliminarily filtered then passes through the high-level filter 313 for further filtration. The high-level filter 313 can select filter elements with different filtration precisions according to needs and can effectively remove pollutants such as fine particles, bacteria, and viruses in the air. The high-level filter 313 is slidably connected to the air inlet pipe 311 through a chute, which is convenient for disassembly and replacement. When the high-level filter 313 needs to be replaced, pull out the high-level filter 313 from the connection port through the handle 1 315 and the connecting plate 1 314. The filtered air enters the connection box 316. A storage drawer 317 is movably connected inside the connection box 316. Solid deodorants and adsorbents and other substances can be placed in the storage drawer 317 to further adsorb odors and harmful substances in the air. When the adsorbent needs to be replaced, pull out the storage drawer 317 from the movable port through the handle 2 319 and the connecting plate 2 318. When the inside of the environmental protection pigsty body 1 needs to be disinfected, the ultraviolet disinfection lamp 322 fixedly installed at the bottom of the connecting seat 321 is turned on to perform ultraviolet disinfection on the air in the pigsty. Ultraviolet rays can destroy the nucleic acid structure of bacteria and viruses, making them lose their activity, thereby achieving the purpose of disinfection. Add the disinfectant into the inside of the water storage tank 327 through the water inlet pipe 328. The water pump 329 starts, pumps out the water in the water storage tank 327 through the water pump 329, and then transports it to the water outlet tank 325 through the water outlet pipe 3212. The motor 323 starts, driving the connecting shaft 324 to rotate, so that the water outlet tank 325 rotates. The atomizing nozzles 326 equidistantly communicated at the bottom of the water outlet tank 325 atomize and spray the water. The water mist fills the pigsty, disinfects the air, and further disinfects and purifies the inside of the environmental protection pigsty body 1.
