Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ion wind generating device that makes it possible to increase the speed of generated ion wind and increase the average wind speed.

First, an example of a conventional ion wind generator will be described using the schematic configuration diagram of FIG. 1.

In the figure, 1 is an ionization electrode that has a needle-like shape and is arranged with the needle tip facing the counter electrode, 2 is a counter electrode that is arranged in a parallel plate shape, and 3 is between the ionization electrode 1 and the counter electrode 2. A DC high voltage power supply connected to the In the above configuration, when a DC high voltage is applied between the ionization electrode 1 and the counter electrode 2 by the DC high voltage power supply 3, a corona is generated at the needle tip of the ionization electrode 1, and due to the corona generation, the ionization electrode 1 and the counter electrode 2 are Current begins to flow between them. This current is generated by ions flowing between the ionizing electrode 1 and the counter electrode 2, and as the ions flow, air movement occurs due to the viscosity of the air. This is an ion wind, and if the arrangement of the ionizing electrode 1 and the counter electrode 2 is considered so that ions flow in a fixed direction, an ion wind directed in a fixed direction can be obtained. Most of the above conventional ion wind generators have a configuration in which two opposing electrodes are provided for one ionizing electrode, so that an ion flow is generated in the direction of the broken line arrow shown in Figure 1. However, the air flow is generated in the direction in which the ion flows (broken arrows) are synthesized, that is, in the direction from A to B.

However, since the direction of the ion flow has a considerable angle 8 as shown in the figure with respect to the direction from A to 8,
A significant portion of the air flow caused by the ion flow was canceled out, making the usable wind efficiency very low. The present invention aims to eliminate the above-mentioned conventional drawbacks and provide an ion wind generator that can generate a strong ion wind. explain.

In FIG. 2, each portion numbered 1 to 3 indicates a common portion with the same numbered portion in FIG. 1, and a description thereof will be omitted. 4, 4', 4'' in the figure are counter electrodes 2
shows an auxiliary electrode held at the same potential as . Auxiliary electrodes 4, 4'
, 4″ is the distance between the tip of the ionizing electrode 1 and the counter electrode 2 (
They are arranged on a circumference whose radius is the length of the ion flow generated between the ionizing electrode 1 and the counter electrode 2, maintaining the same distance relationship as the length of the broken line arrow shown in FIG. As a result, the ion flow produces a radial uniform flow as shown by the dashed arrows in Figure 2, and as a result, the component of the ion wind that goes in the direction of A to B becomes much larger than in the conventional example, and the generated wind speed is increased. Furthermore, since the distances between the ionizing electrode 1, the counter electrode 2, and the auxiliary electrodes 4, 4', and 4'' are all equal, the ion flow becomes uniform, and the ion wind also has a uniform wind speed, which increases the overall average wind speed. It also has the effect of significantly increasing it.

In this embodiment, the ion wind is generated between the ionizing electrode, the counter electrode, and the auxiliary electrode, but the ion wind generator according to the present invention can be used to generate flows of various gases including air. not limited,
It is also effective in generating liquid flow.

Furthermore, although two opposing electrodes are used in this embodiment, the number of opposing electrodes is not limited to two, and for example, three, four,
It is easy to see that the more you increase it, the more effective it will be. The ion wind generating device according to the present invention as described above increases the generated wind speed while significantly increasing the average wind speed, and its application is not limited to gases but also extends to liquids. Its practicality and industrial sound are great.
