The invention relates to an electronic air generator which comprises a power supply
high voltage module, insulating plates, an
anode and cathodes, wherein the
anode and the cathodes are connected through a conducting wire, the
anode is a flat
metal plate distributed with electronic air outlets, and the flat
metal plate as the box bottom and the insulating plates as the box top and the box sides are connected to form a box-shaped structure; air inlets are distributed on the insulating plate as the box top, the cathodes are
metal needles which vertically penetrate through the insulating plate as the box top at the positions among the air inlets and are opposite to the centers of the electronic air outlets, the upper ends of the metal needles are connected in parallel to the conducting wire and are then connected with the power supply
high voltage module, and the included angle between the direction of a
corona field and the direction of airflows passing through the
corona field, i.e. between the central lines of the electronic air outlets is larger than 90 degrees or smaller than or equal to 180 degrees. The efficiency of the electronic air generator can be improved, and the electronic air generator has the characteristics of flexible use and convenient adjustment. Except the electronic air generator, the invention also can design fittings including a sterilizing box, a sterilizing
gun barrel, a
deodorant box and the like which are connected with the electronic air generator so as to be suitable for the application in various occasions.
