Ion air supply module pin grid layout method and ion air supply module

Abstract

The invention provides an ion air supply module pin grid layout method and an ion air supply module. The layout method comprises the following steps of 1, air speed test: adjusting a distance between a single spray point and a metal net to ensure that ion air at a wind speed center point of the metal net has a highest air speed, and measuring a distance L between the tip of the spray point and the metal net; 2, projection radius measurement: measuring an air speed Vr of a measurement point deviating from the air speed center point, and when Vr is equal to aVmax, measuring a distance between an air speed measurement point and the air speed center point as r; and 3, pin grid layout: setting the distances between the tops of the spray points and the metal net in a range of (0.7-1.3)L, and setting the distance between the tips of every two adjacent spray points in a range of (0.7-1.3)L. According to the method, the air supply speed, air output and air supply efficiency of the ion air supply module are improved.

Description

technical field [0001] The invention relates to the technical field of ion air supply, in particular to an ion air supply module needle net layout method and an 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 in the prior art originates 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 , no ionization process takes place. Under the action of the electric field, the charged particles move directionally, and collide with unchar...

AI Technical Summary

Problems solved by technology

In the actual use process, after the number of discharge needles and the position of the metal mesh are determined, in order to obtain a higher wind speed, it is usually achieved by increasing the voltage. However, in the process of increasing the voltage, when the current value increases to a certain When the value is high, there will be a spark discharge phenomenon, which will cause the voltage between the electrodes to drop rapidly, resulting in extremely weak or even no ion wind speed.

It can be seen from the above that the air supply speed, air volume and air supply efficiency of the ion air supply module using the pin mesh structure in the prior art are relatively low
