[0023] Reference Figure 1-3 An air quality monitor comprises a fixed plate 1 and an air monitoring module 2. The side wall of the fixed plate 1 is fixed with a plurality of evenly distributed mounting feet 13, and the mounting feet 13 are provided with mounting holes. Screws are inserted into the interior of the mounting holes so that the mounting feet 13 and the fixed plate 1 are fixedly mounted on the mounting surface. The fixed plate 1 adopts a hollow structure. A mounting plate 3 is fixedly provided inside the fixed plate 1. The air monitoring module 2 is fixedly mounted on the upper surface of the mounting plate 3. A fan 4 is fixedly installed on the inner wall of the fixed plate 1 and above the air monitoring module 2. A fan 4 is fixedly installed on the outer wall of the fixed plate 1 and above the fan An exhaust hole 5 is opened at the position corresponding to the position of the fan 4, and a protective isolation net 8 is fixedly provided inside the exhaust hole 5. The protective isolation net 8 can isolate and protect the exhaust hole 5 to prevent external impurities from entering the interior of the fixed disk 1; the circumferential wall of the fixed disk 1 is fixedly provided with a uniformly distributed first suction pipe 6, and the first suction pipe 6 adopts a telescopic bellows. A second suction pipe 7 is fixedly provided at one end of the multiple first suction pipes 6 away from the fixed disk 1, and an suction hood 12 is fixed at one end of the second suction pipe 7 away from the first suction pipe 6. The suction hood 12 can increase the area of absorbing air and increase the amount of inhaled air.

[0024] By opening the opening of the fan 4, the fan 4 can discharge the gas inside the fixed disk 1 to the outside through the exhaust hole 5, and at the same time, the first intake pipe 6 and the second intake pipe 7 can suck the external air into the interior of the fixed disk 1. Since the length of the first intake pipe 6 and the second intake pipe 7 can be adjusted, the area of the air sucked by the fan 4 can be increased, so that a large area of air can be sucked into the fixed disk 1 and quality detected through the air monitoring module 2, thereby improving the accuracy of air quality monitoring.

[0025] Reference Figure 1-2 An adjustment mechanism is provided between the second intake pipe 7 and the fixed plate 1, and the adjustment mechanism includes a slide rod 9, a sleeve 10 and a bolt 11. The slide rod 9 is symmetrically located on both sides of the first intake pipe 6 and the second intake pipe 7, and one end of the slide rod 9 is fixedly connected to the side wall of the fixed plate 1, the sleeve 10 is fixedly arranged on the pipe wall of the second intake pipe 7, and the sleeve 10 is slidably connected to the slide rod 9. The bolt 11 is threadedly arranged on the side wall of the sleeve 10 and is tightly against the slide rod 9.

[0026] When it is necessary to adjust the end length of the second intake pipe 7, loosen the bolt 11 with a wrench, so that the sliding sleeve 10 slides on the sliding rod 9 and the second intake pipe 7 moves. During the movement of the second intake pipe 7, the first intake pipe 6 is expanded and contracted, thereby adjusting the total length of the first intake pipe 6 and the second intake pipe 7, and absorbing air of different areas.
