Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnet unit, and more particularly to a magnet unit which can obtain a strong magnetic force by combining a magnetic plate and a pair of magnets.

[0002]

2. Description of the Related Art It is known that magnetism has a function of improving blood circulation and improving physical condition by its action to promote physical health, and various health-oriented devices focusing on such health promoting function are known. Has been. For example, actual development Sho 59-18499
In the water purifier disclosed in No. 5, the purified water is magnetized in a strong magnetic field and the magnetically purified water thus obtained is used as drinking water to contribute to health promotion.

Specifically, this is one in which a rod-shaped magnet is exposed and disposed in the water passage of the water purifier body, and by passing purified water through the magnetic field formed by the magnet,
The purified water is magnetized, and the purified water is magnetized in accordance with the magnetic force of the magnet. However, in the above, the magnetic field of the magnet itself must be strengthened in order to strengthen the magnetic field of the space surrounding the magnet, and the magnetic field of the surrounding space cannot be strengthened more than the magnetic force of the magnet. There was a problem.

The present invention has been made in view of the above points,
An object of the invention is to make it possible to strengthen the magnetic field formed in the space near the magnet without increasing the magnetic force of the magnet itself.

[0005]

[Means for Solving the Problems] The technical means of the present invention for solving the above-mentioned problem is that "a pair of magnets (1) and (2) are made to contact one end of the same polar surface with each other and open the other end. 1) (2) is combined, and the above-mentioned open part is closed by a lid (3) made of a magnetic material.

[0006]

The above technical means operates as follows. magnet
(1) Since the facing surfaces of (2) have the same pole and a part of the periphery of the magnetic pole surface is in contact with each other, the facing magnetic pole surfaces of these magnets (1) and (2) The lines of magnetic force coming out of the contact portion are blocked by the contact portion and do not leak out from the portion. Then, the magnetic field lines whose leakage is blocked are absorbed by the side of the cover (3) of the magnetic body that covers the open portion on the opposite side. That is, the lid body (3) collects the magnetic force lines emitted from the magnetic pole surfaces of the magnets (1) and (2) to the lid body (3) side.

[0007]

[Effect] The present invention has the following unique effects. Magnet (1)
Since the magnetic force lines emitted from the magnetic pole surface of (2) are collected on the lid body (3) side, the magnetic field in the space near the surface of the lid body (3) where the magnetic force lines are concentrated becomes strong.

EXAMPLES Next, examples of the present invention described above will be explained.
As shown in FIG. 1, rectangular magnets (1) and (2) have the same poles (N poles in the figure) opposed to each other, and the upper ends thereof are butted to each other to open the lower ends. Then, the lower end open portion is closed with a lid body formed of a ferromagnetic iron plate.

The above-mentioned members are loaded in an extruded resin housing (6), and a through hole (60) is formed in the housing (6) and the through hole (60) is formed. Recesses (11) and (21) for loading the magnets (1) and (2) in the opposed state are formed in the opposing side wall portions of the. And the recess
Magnets (1) and (2) are loaded in (11) and (21) in such a manner that the same poles face each other. Also, a lid is provided on the bottom wall of the through hole (60).
A loading groove (31) for loading the (3) is formed, and the loading groove (31) covers the lower opening of the magnets (1) and (2). Is loaded. Further, in this embodiment, the angle formed between the magnetic pole faces of the magnets (1) and (2) is set to 30 degrees.

In this structure, since the facing magnetic pole faces of the magnets (1) and (2) are both N poles, they do not absorb the magnetic force lines emitted from the respective magnetic pole faces. Further, since the upper ends of the magnetic pole surfaces are in abutting state, magnetic lines of force emerging from the magnetic pole surface are blocked at the abutting portion and do not leak to the outside from the abutting portion. Therefore,
The magnetic force lines emitted from the magnetic pole surface are collected on the lower lid (3) side. Therefore, when the magnetic pole faces of the magnets (1) and (2) are parallel to each other, the magnetic force lines coming out from the magnetic pole faces will diffuse from the entire outer circumference of the gap between the magnetic pole faces, but In the case of the same figure, the magnetic lines of force that originally leak upward (in the direction of the abutting part) have a lower lid.
Collected on the side (3), the magnetic field near the surface of the lid (3) becomes strong, and the density of the lines of magnetic force becomes high. According to the experimental results described later, it was found that the magnetic fields at the lower corners of the through hole (60) were particularly strong.

According to the experimental results, the N poles of the permanent magnets having a magnetic flux density near the magnetic pole surface of 755 gauss are made to face each other, and FIG.
Set the apex angle A at 30 degrees to the magnet (1)
The opening distance L of the lower end opening of (2) was set to 16 mm.
Further, the distance between both magnetic poles (N and S poles) of each magnet (1) (2) is set to 9 mm, and the width of each magnet (1) (2) (in the state shown in FIG. (Corresponding to the length in the direction perpendicular to the paper surface) was set to 58 mm. In this case, the magnetic flux density in the vicinity of both corners below the through hole (60) is 1750 gauss, and the lid body
The magnetic flux density at the center of the upper surface of (3) was 1150 gauss.

Further, under the same conditions as above, when the material of the lid body (3) is changed from iron as a ferromagnetic material to aluminum as a paramagnetic material, the lower corners of the through hole (60) are used. The magnetic flux density in the device was 1224 gauss. Furthermore, the lid (3)
If copper is used as the diamagnetic material, the through hole (60)
The magnetic flux density in both lower corners of the was 1224 gauss.

When the iron lid 3 is used and the apex angle A is set to "45 degrees", the magnetic flux density at both lower corners of the through hole 60 is 1560 gauss, and Set the apex angle A to "60
When set to "degrees", it was 1560 gauss. Therefore, when the magnet unit of the above-mentioned embodiment is incorporated into a water purifier to impart magnetism to the purified water obtained from the water purifier, it is necessary to pass through both corners below the through hole (60). The water pipe (7) should be inserted through the.

When purified water or the like is passed through the water passage pipe (7), the purified water passes through a strong magnetic field, so that the purified water can have relatively strong magnetism. By using this as drinking water, it is possible to obtain a water purifier that can contribute to health promotion such as improvement of blood circulation. Although the lid body (3) is formed in a flat plate shape in the above embodiment, the lid body (3) may be formed in an arc shape as shown in FIG. In such a case, the magnetic forces at the corners (4) (5) below the through hole (60) surrounded by the magnets (1) (2) and the lid (3) become particularly strong.

In addition to the above-mentioned water purifier, the present invention can also be used in the case where a fluid fuel such as gas or oil is magnetized to obtain a fuel having a high heat generation efficiency.
