This invention discloses an outdoor
environmental monitoring device and its monitoring method, relating to the field of outdoor
environmental monitoring and
processing technology. It includes a directional atomizing device G, comprising a housing with a fan fixed to its outer wall. The housing contains an atomizing
nozzle, a
corona needle, and a magnetic pole at opposite ends. The housing, the converging and expanding flow channels constrain the droplet movement flow field, preventing non-target drift, and simultaneously providing a closed environment for the formation of electric and magnetic fields, ensuring effective charging and directional transport. Employing atomizing components, a
discharge component, and a magnetic pole component, based on the synergistic effect of "
electric force + magnetic force +
airflow thrust," it achieves uniform charging and stable directional transport of droplets, overcoming the shortcomings of uneven charging and poor target targeting in existing technologies, and improving droplet utilization and operational accuracy.
