The generation of ionic wind is derived from the corona discharge principle: due to the action of high voltage, the electric field intensity near the needle electrode is extremely high, so that a large number of air molecules in the area are ionized, and the electric field outside the area is weak, so that the ionization process is not generated. Under the action of the electric field, the charged particles move directionally and collide with uncharged neutral particles in the movement process, and part of kinetic energy is transferred to the neutral particles, so that the neutral particles move directionally together, namely, ion wind is generated. However, in practical experiments or use, it is found that the wind speed and wind volume of the ion wind generated by the above principle are limited, so that the practical application field and the application range are narrow. Also, due to the above problems, the technique of blowing air by ion wind has been limited to the most basic theoretical level.

Detailed Description
First, an ion wind generating device according to an embodiment of the present invention is provided, fig. 1 is a schematic structural view of an ion wind generating device according to an embodiment of the present invention, and fig. 2 is a schematic structural exploded view of an ion wind generating device according to an embodiment of the present invention. Referring to fig. 1 and 2, the ion wind generating device 10 includes a plurality of discharge modules arranged in sequence, each of which includes a mesh electrode vertically disposed and extending in a transverse direction and a plurality of needle electrodes distributed at one side of the mesh electrode. It is emphasized that references to a plurality in embodiments of the present invention mean two, three or more than three. Specifically, the mesh electrode may be a metal mesh having square holes, diamond holes, circular holes, or other shaped through holes. The needle electrode may be a discharge needle made of a metal material, and has a discharge tip, and the discharge tip may be directed to the center of a through hole of the mesh electrode.
Fig. 3 is a schematic front view of a pin grid layout of an ion wind generating device according to an embodiment of the present invention, fig. 4 is a schematic side view of a pin grid layout of an ion wind generating device according to an embodiment of the present invention, and fig. 5 is a schematic top view of a pin grid layout of an ion wind generating device according to an embodiment of the present invention. For convenience of description and understanding of the technical solution of the present invention, directional coordinates are given in fig. 3 to 5, wherein the OX direction denotes a front-back direction, and the direction indicated by the OX arrow is front and the direction indicated by the arrow facing away from the OX arrow is back; the OY direction represents a lateral direction; the OZ direction represents the vertical direction. Referring to fig. 3 to 5, the needle electrodes of each two adjacent discharge modules are arranged in a staggered manner in a direction perpendicular to the air outlet surface (i.e., a plane perpendicular to the OX direction and located on the front side) of the ion wind generating device 10, and the projections of the needle electrodes of each two adjacent discharge modules on the air outlet surface of the ion wind generating device 10 are located on the same horizontal line. That is, the needle electrodes of every two adjacent discharge modules are arranged in a staggered manner, but the heights of the needle electrodes are the same (i.e., there is no height difference between the needle electrodes of every two adjacent discharge modules in the Z direction). Therefore, uniform soft wind can be generated in a plurality of linear regions in the horizontal direction, and the superposition of a plurality of discharge modules can form a larger and stronger electric field in the linear regions, so that the wind speed of the ion wind in the linear regions is relatively higher. The ion wind generated by the ion wind generating device of the invention is blown to the user body, so that the user has relatively strong soft wind feeling.
The following describes the technical solution of the present invention in detail by taking an example that the ion wind generating device 10 includes two discharge modules arranged in sequence.
In some embodiments of the present invention, the number of the discharge modules may be two, that is, the front stage discharge module 100 located at the front side in the air outlet direction of the ion wind generating device 10 and the rear stage discharge module 200 located at the rear side in the air outlet direction. The pre-stage discharge module 100 has a mesh electrode 110 and a plurality of needle electrodes 120, and the post-stage discharge module 200 has a mesh electrode 210 and a plurality of needle electrodes 220. In the front view shown in fig. 3, the structure of the front stage discharge module 100 is shown by a solid line and the structure of the rear stage discharge module 200 is shown by a dotted line for easy understanding. The needle electrode 120 of the front stage discharge module 100 and the needle electrode 220 of the rear stage discharge module 200 are offset from each other, but have no height difference in the OZ direction. In the side view shown in fig. 4, the corresponding needle electrode 120 of the front stage discharge module 100 and the corresponding needle electrode 220 of the rear stage discharge module 200 are at the same height position, i.e., on a horizontal line. In the top view shown in fig. 5, the respective needle electrodes 120 of the front stage discharge module 100 and the respective needle electrodes 220 of the rear stage discharge module 200 are on different straight lines extending in the front-rear direction (i.e., parallel to the OX direction).
In some embodiments of the present invention, each set of three needle-shaped electrodes formed by the needle-shaped electrodes of the plurality of discharge modules in the horizontal plane and adjacent to each other forms an isosceles triangle in projection, so as to ensure that the ion wind generated by the ion wind generating device 10 is distributed more uniformly. Also taking two discharge modules as an example, referring to fig. 5, the projections formed in the horizontal plane by two adjacent needle electrodes 120 of the front discharge module 100 and the projections formed in the horizontal plane by the needle electrodes 220 adjacent to both needle electrodes 120 of the rear discharge module 200 (i.e., the needle electrodes 220 located between the two needle electrodes 120 in the OY direction) form an isosceles triangle. Similarly, the projections of the two adjacent needle electrodes 220 of the later-stage discharge module 200 in the horizontal plane form an isosceles triangle with the projections of the needle electrodes 120 of the earlier-stage discharge module 100 adjacent to both needle electrodes 220 (i.e., the needle electrodes 120 located between the two needle electrodes 220 in the OY direction) in the horizontal plane.
In some embodiments of the present invention, the plurality of needle electrodes of each discharge module are parallel to each other and perpendicular to the plane of the mesh electrodes of the discharge module, so as to ensure that each needle electrode and the corresponding mesh electrode can generate a relatively obvious discharge phenomenon, thereby generating an ion wind with a relatively high intensity.
In some embodiments of the present invention, the tips of the plurality of needle electrodes of each discharge module are located in the same plane, so as to ensure that the intensity of the ion wind generated between each needle electrode and the corresponding mesh electrode is the same, so that the ion wind generated by the ion wind generating device 10 as a whole is relatively uniform.
In order to increase the blowing speed of the ion wind generating apparatus 10, the designer of the present invention performed a large number of wind speed measurement experiments, and found that the distance L between the tip of each needle electrode and the mesh electrode was set so as to satisfy L ═ a L1(wherein a is any constant in the range of 0.7-1.3, i.e. a can be 0.7, 0.8, 0.9, 1.0, 1.1, 1.2 or 1.3, L1To maximize the ionic wind speed at the wind speed center point of the mesh electrodeHigh wind speed VmaxThe distance between the tip of the needle-shaped electrode and the mesh electrode, and the wind speed central point of the mesh electrode is the projection point of the tip of the needle-shaped electrode on the mesh electrode), on the one hand, the wind speed of the ion wind generated by the ion wind generating device 10 can better meet the normal use requirement of a user, and on the other hand, the needle-shaped electrode can be partially overlapped in the region where the mesh electrode generates effective ion wind to achieve the projection effect of the shadowless lamp, so that the ion wind distribution of the mesh electrode is more uniform.
Further, in order to increase the amount of air blown by the ion wind generating apparatus 10, the designer of the present invention has conducted a large number of experiments for measuring the projection radius of the needle tip, and as a result of the experiments, it was found that the distance R between the tips of two adjacent needle electrodes is set so as to satisfy R ═ aR1(wherein, R1For the wind speed to reach the maximum wind speed VmaxB times the distance between the wind speed measurement point and the wind speed central point, wherein b is any constant in the range of 0.3-0.7, namely b can be 0.3, 0.4, 0.5, 0.6 or 0.7, and a is the same as above), the air volume of the ion wind generated by the ion wind generating device 10 can better meet the normal use requirements of users. Meanwhile, after the distance between two adjacent needle electrodes is specially designed, the mutual offset of wind speeds caused by too close distance between two adjacent needle electrodes can be avoided, and the reduction of wind volume and the uneven distribution of wind volume caused by too far distance between two needle electrodes can be avoided.
It is emphasized that the maximum wind speed V is here referred tomaxAll reference wind speed values are given on the premise that the voltage value between the needle electrode and the mesh electrode is constant.
Therefore, the ion wind generating device 10 can generate the uniform ion wind with larger wind quantity by reasonably designing the spatial position relationship between the needle electrodes and the mesh electrodes and reasonably arranging the position relationship among the needle electrodes, so that the air supply speed, the air supply quantity and the air supply efficiency of the ion wind generating device 10 are improved.
