When the air contacts the return pipe 4, the cooling water in the circulating pipe absorbs the temperature of the air, thereby reducing the temperature in the air. One end of the return pipe 4 is fixedly connected to a first extension pipe 5, and the other end of the return pipe 4 is fixedly connected to a second extension pipe 5. A one-way valve 21 is provided on the long tube 6, the first extension tube 5 and the second extension tube 6, the one-way valve 21 can prevent the cooling water from flowing back, the other end of the first extension tube 5 is fixedly connected to the first water tank 8, the other end of the second extension tube 6 is fixedly connected to the upper surface of the first water tank 8, and a water pump 7 is provided on the second extension tube 6. The water pump 7 draws cooling water from the first water tank 8 through the second extension tube 6, and then transports it to the circulation pipe from the other end of the second extension tube 6. The interior of the first water tank 8 is fixedly connected with two first filter plates 9, and the first filter plates 9 are used to filter the cooling water. The lower surface of the first water tank 8 is fixedly connected to the upper surface of the sampling house 1.

An air inlet pipe 13 is fixedly connected to the upper surface of the filter box 11, and an air pump 14 is arranged on the air inlet pipe 13. The air pump 14 inhales air through the air inlet pipe 13 and then discharges it into the water in the first water tank 8, so that dust in the air is mixed with water. A through pipe 15 is fixedly connected to the interior of one side of the second water tank 12, and air is introduced into the filter box 11 through the through pipe 15. Two guide plates 16 are fixedly connected to one side of the interior of the filter box 11, and harmful substances in the air are absorbed through the filter filling on the guide plate 16.

When the air contacts the return pipe 4, the cooling water in the circulation pipe absorbs the temperature of the air, thereby lowering the temperature in the air. After that, the cooling water in the circulation pipe is discharged from the other end due to the delivery pressure of the water pump 7 and transported to the first extension pipe 5, and then refluxes into the first water tank 8, and a first filter plate 9 is provided in the first water tank 8 to filter the cooling water. Before the fan 3 sucks air, the air pump 14 on the filter box 11 is started, and the air pump 14 passes through the intake pipe 1 3 The air is inhaled and then discharged into the water in the first water tank 8. At this time, the air and the water are mixed, and the dust in the air is mixed with the water, and then the dust is settled in the water, and the air exists in the upper part of the water tank. Then the air is transported to the filter filling on the guide plate 16 by the air pipe 15 to absorb harmful substances in the air, and then the baffle 17 of the air pipe 15 is opened to discharge it to the lower part of the filter box 11. At this time, the air contacts and filters the two second filter plates 18 in the filter box 11 to further increase the filtering effect, and then the outside air is more comprehensively filtered and purified, and the connection block 19 can be pulled out by the handle 20 to replace the second filter plates 18 to prevent the problem of reduced filtering effect after long-term use.
