The invention discloses a multi-
ion-field
indoor air purifier. The multi-
ion-field
indoor air purifier comprises a power source, a suction opening, a filter, a
plasma reactor, a suction device and an exhaust port. The
plasma reactor comprises a plurality of pole plates which are arranged in a layering manner, and the positive electrodes and the negative electrodes of the pole plates are arranged in a staggered manner. The polarities of the vertically adjacent pole plates are opposite. After all sets of electrodes of the multi-
ion-field low-temperature
plasma reactor form ion field units, a plurality of ion fields are formed among the ion field units. Under the same
electric power, the efficiency of the reactor is improved in a multiplied manner, and
energy consumption is saved in a multiplied manner. An upper-suction and lower-exhaust air
processing structure is adopted, the height of the
machine type is more than 1,000 mm and is close to the suspension height of polluted air, the phenomenon of the air
short circuit is avoided, and the indoor space is rapidly purified completely. An
airflow channel of the multi-ion field low-temperature
plasma reactor is designed to be of the structure vertically circulating with the multi-hole pole plates, and the circulation amount is large while blockage cannot happen. The
airflow channel can be easily taken out to be cleaned and recycled, and the using cost is greatly reduced.
