Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

The utility model provides an ambient air monitoring device, includes sampling pipe 1, box 2 and filter assembly 3, install at the top of box 2 sampling pipe 1, install at the top of box 2 filter assembly 3, filter assembly 3 includes support 31, fan 32, connecting pipe 33, filter equipment 34 and intake pipe 35, the top of box 1 is close to install on the right side of sampling pipe 1 fan 32, fan 32's exit end fixedly connected with the entrance point of sampling pipe 1, fan 32's entrance point with filter equipment 34's one end is passed through connecting pipe 33 links to each other, install at the top of box 2 support 31, install at the top of support 31 filter equipment 34, filter equipment 34's other end fixedly connected with intake pipe 35.

Specifically, the fan 32 is connected with the sampling pipe 1 through a hose, and the fan 32 is connected with the sampling pipe 1 through a hose, so that the operation is convenient.
