The blower A consists of the counter electrodes 3 provided on both sides of the opening 14, discharge electrodes 1 arranged in the side wall 13 with a specified distance between, and the high voltage generator. In this constitution, when negative voltage is impressed on the discharge electrodes 1, for example, winds flow from the side of the discharge electrodes 1 to the side of the counter electrodes 3, and the individual flow of air flowed from the opening 14 along the inner wall of the casing 10 are formed. These individual flows are synthesized by the expanding angle of the casing 10 into a high pressure wind, which is discharged from a discharge opening 11.

), the cations (9) gather to form an ion sheath to prevent dielectric breakdown. The electrons (8) are accelerated by the action of the electric field, and collide to form anions (6), or recombine to form neutral molecules (forces that form the opposite electrode (
3) Move to the side. These movements generated wind.

[Problem that the invention seeks to solve]

In the conventional blower as described above, air is ionized by corona discharge, and this ionized air is discharged with electric current f!
The problem is that high wind pressure cannot be obtained because the wind is only generated by ejecting the needle from the +11 needle electrode (2) at high speed by the action of an electric field, colliding with molecules in the air, and recombining. There was a point.

This invention was made to solve the above problems, and an object thereof is to provide an air blowing device that can obtain high wind pressure.

[Means for solving problems]

The air blower according to the present invention includes a side wall formed in a cylindrical shape, a casing having a predetermined spread angle with respect to the side wall and a discharge port formed at an end, and a casing having a predetermined interval in the air blowing direction on the side wall. a plurality of air blowers arranged along the inner wall of the casing to blow air along the inner wall of the casing; It is formed from a high voltage generator that applies a high voltage between opposing electrodes.

[Effect]

In this invention, the individual air flows discharged from each blower are caused to flow along a casing formed with a predetermined spread angle, so that each individual air flow is combined into a high pressure and discharged from the discharge port. be done.

Side casings (12) on both sides of the casing
is provided. (13) means that this casing is placed inside the casing α0) at a predetermined spread angle θ as shown in Figure 2.
The side wall is formed into a cylindrical shape and has at least one end opening to the outside of the side casing (12). (14) is a plurality of openings provided at predetermined intervals in this side wall, and in these openings, the blower (A) is provided with counter electrodes (3) on both sides of the opening (14), and is connected to the counter electrodes at predetermined intervals. Discharge electrodes (1) are attached to the side wall (13) at intervals.
The discharge electrode (1) and the counter electrode (3) are arranged in a positional relationship such that the wind generated thereby flows along the inner wall of the casing α0). Although not shown, the discharge electrode (1) and the counter electrode (3) are connected to the high voltage generator (4) and the ground (5) as in the conventional case.

In the blower device configured as described above, by applying a negative voltage to the discharge electrode 11), the blower (A) is operated from the discharge electrode (1) side to the counter electrode (-
