The windward bucket 32 is connected with the water tank 33 through an air inlet pipe 36, an air outlet of the air inlet pipe 36 extends to the inner bottom of the water tank 33, an exhaust fan 37 is arranged on the air inlet pipe 36, the water tank 33 is connected with the cooling box 31 through an air duct 41, the air duct 41 is connected with the cooling box 31 through a first air bucket 42, a plurality of cotton filtering plates 43 are horizontally fixed in the first air bucket 42, a cooling pipe 34 is spirally bent and arranged, the cooling pipe 34 is vertically arranged inside the cooling box 31, a plurality of spray heads 30 are fixed on the left inner wall and the right inner wall of the cooling box 31, a liquid nitrogen tank 35 is connected with the spray heads 30 through a first conduit 38, and an electromagnetic valve 39 is arranged on the. One end of the second conduit 40 is connected with the top of the cooling tank 31, the other end of the second conduit 40 extends into the water tank 33, the part of the second conduit 40 located in the water tank 33 is spirally arranged, the stirring wheel 47 is rotatably connected with the inner wall of the water tank 33, a plurality of stirring plates 48 are arranged on the stirring wheel 47 at equal angles, and the stirring wheel 47 is arranged on one side of the outlet of the air inlet pipe 36. The cooling pipe 34 is connected to an air outlet funnel 53 through an air outlet pipe 51, and the air outlet funnel 53 is connected to the compressor 22.

In operation, the suction fan 37 is activated to draw air from the outside through the windward bucket 32. The outside air enters from the windward bucket 32, is discharged through the intake pipe 36, and as the intake pipe 36 is discharged into the water tank 33, the water tank 33 is filled with water, and the output end of the intake pipe 36 goes deep into the water. The air from the air inlet pipe 36 enters the water in the water tank 33, and during the air rising process, the dust and impurities mixed in the air can be flowed down by the water in the water tank 33, and when the air flows through the water, because the air is fully contacted with the water, and the temperature of the water filled in the water tank 33 is lower than the room temperature, the air can be purified and simultaneously exchanges heat with the water, and the water in the water tank 33 absorbs the heat to reduce the temperature. After being blown from the water tank 33, the air flows to the first air scoop 42. When air passes through the multiple layers of the cotton filter plates 43 arranged on the first air scoop 42, the cotton filter plates 43 absorb moisture carried by the air, so that the air is dried. The air is then directed into the cooling tubes 34. The cooling pipe 34 is arranged to be bent and detoured in the cooling tank 31 to lengthen a path through which air flows. When the air enters the cooling pipe 34, the electromagnetic valve 39 is opened, the liquid nitrogen stored in the liquid nitrogen tank 35 is sprayed onto the cooling pipe 34 through the spray head 30 through the first conduit 38, the air flows in the cooling pipe 34 in a bending manner, heat exchange is performed with the liquid nitrogen outside the pipe in the flowing process, and the air is cooled to a low temperature.

The low-temperature air flows out of the cooling pipe 34, flows into the air outlet funnel 53 through the air outlet pipe 51, flows into the compressor 22, and is supplied to the compressor 22 to be compressed. The air with low temperature enters the compressor 22, which is beneficial to improving the refrigeration efficiency of the compressor 22, and further improving the cooling effect on the motor 21.

When the air drawn from the outside by the exhaust fan 37 is output from the air inlet pipe 36, the air is blown to the stirring wheel 47 on the outlet side of the air inlet pipe, the stirring wheel 47 rotates under the blowing of the input air, and the rotating stirring wheel 47 can stir the water in the water tank 33, so that the water cooled by the second conduit 40 is fully mixed with other water in the water tank 33, and the water in the whole water tank 33 can be cooled. Meanwhile, the sucked air is blown to the stirring wheel 47, and rises to leave the water along with the rotation of the stirring wheel 47 to the highest position, so that the contact time of the air and the water is prolonged, and dust in the air is left in the water as much as possible. Not only has the effect of cooling water, but also can enhance the cleaning effect of water.

In the process of drawing air by the air drawing fan 37, the first filter screen 61 blocks the dust and impurities mixed in the air, and reduces the dust entering the windward bucket 32. When a certain amount of dust is blocked on the first filter screen 61, the dust soaking roller 65 slides along the slide rails 63 on both sides. The gear 66 on the dust dipping roller 65 is meshed with the saw teeth 64, so that when the dust dipping roller 65 slides up and down, the dust dipping roller 65 can rotate, and meanwhile, the dust dipping roller 65 is tightly attached to the first filter screen 61, so that when the dust dipping roller 65 rotates, dust impurities on the first filter screen 61 can be stuck by the adsorption silica gel 67 on the dust dipping roller 65, when the dust dipping roller 65 is fully stained with dust fragments, the dust on the surface can be washed away only by water washing, and the dust dipping roller 65 can be used again.
