In-vehicle plasma negative ion air purification device utilizing vehicle air conditioning airflow

Abstract

A vehicle-mounted plasma negative ion air purification device utilizing vehicle air conditioning airflow includes a main body that can be fixed to the air conditioning vent of a vehicle. The main body has an air inlet and a plasma negative oxygen ion generating unit that generates a high-voltage electric field to create high-voltage ionization, thereby generating negative oxygen ions. The main body also has a front cover with an air outlet corresponding to the air inlet. In addition to achieving air purification, deodorization, and antibacterial effects, it also has the advantages of eliminating the need for a built-in fan, requiring no consumables, and being easy to disassemble by using the airflow from the vehicle air conditioning vent as the sole driving airflow source.
