[0028] The lower portion of rain cover 2 is provided with air detector 4, air detector 4 can be directly fixedly connected with support rod 1 using connecting assembly, for example, hoop, bolt and the like. It can also be installed using bearing seat 5 stated in detail below, and rain cover 2 is used for preventing rain for air detector 4 below.

[0029] Support rod 1 has hollow channel 12 in the inside, and through hole two 8 is formed in the side wall of support rod 1 and is communicated with hollow channel 12, and through hole one 7 is formed in rain cover 2 and is communicated with hollow channel 12, through hole two 8 is located near air detector 4, and is preferably arranged below air detector 4, that is, the setting position of through hole two 8 is lower than air detector 4, in the monitoring process, based on Bernoulli's principle, the special arc structure of the top of rain cover 2 makes the air flow rate passing through the top surface thereof faster, causing the air pressure at through hole one 7 to decrease. Under the driving of this pressure difference, the air near air monitor can quickly enter the hollow channel 12 of support rod 1 through through hole two 8 and be discharged from through hole one 7. The circulation process accelerates the air renewal speed around air monitor.

[0030] The support rod 1 is provided with a supporting seat 5 for supporting the air detector 4, the height of the supporting seat 5 is adjustable, the supporting seat 5 is slidable along the support rod 1, the bottom of the supporting seat 5 is provided with a sleeve 9 sleeved on the outer wall of the support rod 1, the outer wall of the sleeve 9 is threadedly connected with a jackscrew 6, the screwing end of the jackscrew 6 can abut against the outer wall of the support rod 1, and the height of the supporting seat 5 can be adjusted by loosening the jackscrew 6, so that the height of the air detector 4 is adjusted, and the position of the supporting seat 5 is fixed after the jackscrew 6 is tightened.

[0031] Due to the arrangement of the supporting seat 5, other obstructions are caused, so that a guide pipe 10 with one end communicating with the through hole two 8 is arranged on the support rod 1, and the other end of the guide pipe 10 is close to the air detector 4.

[0032] The lower surface of the rain cover 2 is provided with a downward protruding stopper 11, which prevents rainwater from flowing inward and dripping on the air detector 4.

[0033] In summary, the atmospheric environment monitoring device has the advantages that in use, the air detector 4 is installed below the rain cover 2, so that the detection part of the air detector 4 is in the best detection position, and the through hole two 8 on the side wall of the support rod 1 is located near the air detector 4, and the installation can be carried out through the installation assembly or the supporting assembly.
