Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention moves air or other insulating fluids without mechanical parts, and in the process of moving air or other insulating fluids, removes impurity particles and contaminants contained in the fluid. This invention relates to an ionic air purifier that removes particles, etc.

Conventional configuration and its problems Conventionally, ion winds induced by cycorona discharge have been observed, and the principle of their generation will be briefly explained. Ionic wind is a phenomenon in which ions generated by corona discharge move along the lines of electric force, and in the process of this movement, they repel many neutral molecules and create a flow of single molecules, that is, wind. .

By using this ionic wind, it is possible to circulate air without using a fan, and if this is applied to an air purifier, it will be possible to create an air purifier that has features such as noiseless, small size, and low cost. can do. The electrode configuration of this ion wind air cleaner will be explained with reference to FIG. This consists of a discharge electrode (hereinafter referred to as ionization line) 1 that generates a corona discharge, a parallel plate-shaped counter dust collection electrode 2 installed at a constant interval, and a flat plate that generates a high electric field between the counter dust collection electrode 2. It is composed of an auxiliary electrode 3 having a shape. DI, D2 are high voltage power supplies, E
represents earth.

The principle of operation is that a high voltage is applied between the ionized wire 1 and the counter electrode 2 to generate corona discharge, inducing an ion wind as shown by the arrow in Figure 1, sucking and exhausting the processing air, and Dust in the air is charged and collected on the electrode 2 by a high electric field between the electrodes 2 and 30. The above is the operating principle of ion wind.

Conventionally, in this type of air purifier, the ionization wire, which is the ionization electrode, is attached to a frame 6 made of aluminum or iron plate, and a tension spring 4 made of stainless steel or spring steel, as shown in FIG. Attach the spring 4
This uses a structure in which an ionized wire 6 is wound around the wire. 6' represents the winding part.

Figure 3 is an enlarged depiction of the entrance in Figure 2.
The ionization amount of the ionization wire used for this differs depending on the concentration density of the electric lines of force, and it is necessary to use a wire with an extremely thin diameter.In the conventional method of winding the ionization wire, care must be taken not to break the ionization wire. The ionization line is extremely thin (6) and is not easy to automate.
0 μ to 120 μ [, and scratches etc. easily appear on the wire,
The variation in tensile strength was not uniform and reliability was low. In addition, some other methods have been adopted, such as the method shown in Fig. 4, where both ends of the ionized wire 60 are completely closed using crimp terminals 7, but this method has problems in terms of workability and tensile strength. The reality is that this is not enough.

OBJECTS OF THE INVENTION The present invention obviates these conventional drawbacks.
The purpose is to improve workability and reliability.

Structure of the Invention In order to achieve the object of the present invention, both ends of the ionization wire are stapled and fastened with rivets or the like.

DESCRIPTION OF THE EMBODIMENTS As shown in FIG. 6, the present invention is a mosquito repellent device in which an ionized wire 6 is wound two to three times around an eyelet 8 made of aluminum. Figure 6 shows the tightening method, in which the stopper 8 is fixed to the jig 10, the ionized wire is completely wrapped two or three times, and the wire is positioned securely so that it does not move. It is tightened with a constant pressure in the direction of the arrow using a tightening jig 9.

At this time, there are various ways of tightening depending on the shape of the tightening jig 9.
It is important to have the most suitable structure for the shape of the tightening jig and the shape of the eyelet.

FIG. 7 shows the state after the mosquito bite, and a complete comparison shows that the ionized wire was not damaged and the tensile strength was sufficiently satisfactory.

FIG. 8 shows the results of the tensile strength test. M is the conventional winding method, B is the crimp terminal method, and C is the eyelet method of the present invention. As can be seen from the test results, eyelet method C had the best tensile strength, and by making many sharpening jigs, it had a structure that was easy to automate.

Effects of the Invention As described above, the present invention improves the workability of the ionizing wire, increases the tensile strength, and provides a fanless air cleaner that is even more reliable than the conventional one.
