Ball net type ion air supply module

Abstract

The invention provides a ball net type ion air supply module including a plurality of discharge needles and a metal net. The metal net includes a frame and metal wires wound on the frame. The metal wires form multiple cross nodes in the area formed by the frame. The tip of each discharge needle is arranged opposite to the corresponding cross node. The air supply speed, the amount of air supplied and the air supply efficiency of the ball net type ion air supply module are improved.

Description

technical field [0001] The invention relates to the technical field of ion air supply, in particular to a ball net type ion air supply module. Background technique [0002] At present, as a unique air supply system, corona discharge ion air supply technology has become a technology with great market potential and good application prospects due to its simple structure, no noise, and air purification effect. It is a hot research direction of domestic and foreign researchers. The generation of ion wind comes from the principle of corona discharge: due to the effect of high voltage, the electric field strength near the needle electrode is extremely high, which causes a large number of air molecules in the area to be ionized, while the electric field outside this area is weak, and no ionization occurs process. Under the action of the electric field, the charged particles move directionally, and collide with uncharged neutral particles during the movement, and transfer part of t...

AI Technical Summary

Problems solved by technology

The needle mesh discharge ion wind module in the prior art is composed of discharge needles and metal mesh, and the metal mesh is usually fixed on the frame after cutting with metal mesh cloth. The flatness of the metal mesh is low, so that the gap between the needle and the mesh The distance cannot be effectively controlled. The needle net discharge ion air module is limited by the discharge needles at the shortest distance from the metal net, and the maximum current value applied is small. Low air volume and air supply efficiency
