[0025] Here’s how it works:

[0026] First, the new device is placed at the required location and connected to the circuit;

[0027] Second, by controlling the operation of the duct fan 2, the duct fan 2 uses the first air inlet pipe 31 of the suction structure 3 to suck the external air into the suction pipe 37. By using the single-open double-control of the first air inlet pipe 31 and the second air inlet pipe 32, the user can keep the first air inlet pipe 31 and the second air inlet pipe 32 always having only one air inlet. By controlling the electric scissor-type telescopic frame 36 to extend and retract, the electric scissor-type telescopic frame 36 can drive the fixed plate 38 to move up and down, and the fixed plate 38 drives the second air inlet pipe 32 to move up and down, thereby achieving the effect of sucking in air at different heights.

[0028] Third, the gas is transported to the outlet pipe 47 through the intake pipe 37 and the duct fan 2, and finally enters the inner wall of the housing 41, and is detected by the formaldehyde sensor 44, the dust sensor 45 and the temperature and humidity sensor 46 in turn. The formaldehyde sensor 44, the dust sensor 45 and the temperature and humidity sensor 46 feed back the detection data to the external controller. When the formaldehyde or dust or temperature and humidity in the gas exceed the standard, the external controller controls the corresponding electric three-way reversing valve 59 of the first connecting pipe 51, the second connecting pipe 53 or the third connecting pipe 55 to perform corresponding reversal. If the formaldehyde sensor 44 detects that the formaldehyde exceeds the standard, the gas enters the formaldehyde processor 52 from the first connecting pipe 51 for processing, and the electric three-way reversing valve 59 of the second connecting pipe 53 is reversed, so that the processed gas is transported upward from the second connecting pipe 53 to the exhaust pipe 58 for discharge. If all three sensors detect that the gas exceeds the standard, the gas will be processed in turn through the formaldehyde processor 52, the dust processor 54 and the temperature and humidity processor 56, and finally discharged to the discharge pipe 58 through the fourth connecting pipe 57.
