Description

[Detailed description of the invention] [Field of industrial application] This invention is used to magnetize and activate fluids such as household drinking water, agricultural or industrial water, or oil using a permanent magnet to reform and purify the water. The present invention relates to a fluid magnetic processing tool. More specifically, the present invention relates to a fluid magnetic treatment tool that is attached to a conduit such as a water pipe and performs magnetic treatment on fluid flowing through the conduit.

[Conventional technology]

Conventionally, in this type of fluid magnetic processing tool, a pair of semi-cylindrical magnet holders containing permanent magnets are faced to each other, and one circumferential end of the magnet holder is connected so as to be openable and closable by a shaft, etc. It is known that a device is provided with a stopper such as a locking hook at the end so that it can be easily attached to an existing water pipe or other conduit (for example, see Japanese Utility Model Application Publication No. 123297/1987). .

[The problem that the idea aims to solve]

However, in the conventional method described above, in which a pair of semi-cylindrical magnet holders are connected so as to be openable and closable by a shaft or the like, and the end opposite to the shaft is fixed with a stopper, the adhesion force to the conduit is weak. Particularly when it is attached to a vertically installed conduit, there is often a risk of it falling downward. Another problem was that it could only be attached to a conduit having an outer diameter approximately equal to the inner diameter of the magnet holder.

The present invention was proposed in view of the above-mentioned problems, and is a fluid magnet that can be securely attached to and held in conduits such as water pipes, and can also be used for various types of conduits with slightly different outer diameters. The purpose is to provide processing tools.

[Means to solve the problem]

The present invention consists of a pair of semi-cylindrical magnet holders containing permanent magnets facing each other, one circumferential end of each of the magnet holders being connected in an openable/closable manner with a shaft, and both magnet holders being normally closed. It is characterized by being equipped with a spring that biases the rotation.

[Effect]

As described above, when the magnet holder is attached to the outer circumferential surface of a conduit such as a water pipe, by providing a spring that always rotates and biases both magnet holders connected by the shaft so that they can be opened and closed in the closing direction. The above-mentioned springs allow the inner peripheral surface of each magnet holder to be tightly fixed to the outer peripheral surface of the conduit, and it is also possible to attach the magnet holder to conduits having somewhat different outer diameters.

〔Example〕

FIG. 1 is a front view showing an embodiment of the fluid magnetic processing tool according to the present invention, FIG. 2 is a cross-sectional plan view thereof, and FIG. 3 is a side view thereof.

In the figure, reference numerals 1 and 1 indicate a pair of magnet holders made of a non-magnetic material, and each magnet holder 1 is molded in a substantially semi-cylindrical shape from synthetic resin in this example.
A permanent magnet 2 such as a rectangular parallelepiped ferrite magnet, which is elongated in the axial direction, is embedded in the magnet holder 1 during molding.

Two or more magnets 2 may be provided in each magnet holder 1 in the circumferential direction, as shown in FIG. Further, each magnet 2 has both poles N and S of the semi-cylindrical holder 1.
At the same time, the radially inner (inner side) poles of each magnet 2 are arranged in the circumferential direction (clockwise) in order of N, S, N,
S, or N, N, S, S is preferable. In this way, a substantially uniform magnetic field can be formed in each part of the cross section of the conduit P. Further, the material, shape, etc. of the magnet 2 can be selected as appropriate, and if a magnetic body such as a piece of iron is provided on the outer surface of the magnet 2, the magnetic field inside the conduit can be made even stronger.

Further, both the magnet holders 1, 1 in the illustrated example are formed in the same shape, and the protrusions 1a formed on one end side in the circumferential direction of each magnet holder 1 are engaged with each other in a staggered manner. 3, they are connected so that they can be opened and closed.

A torsion coil spring 4 is provided in the center of the shaft 3 so as to be inserted through the shaft 3, and both ends of the spring 4 are brought into contact with the outer peripheral surface of each magnet holder 1, 1. Both the holding bodies 1, 1 are always urged to rotate in the direction of closing them into a cylindrical shape.

Note that the above-mentioned shaft 3 and spring 4 may be made of non-magnetic material to prevent magnetic leakage.

In the above configuration, both the holding bodies 1, 1 are connected by the spring 4
By opening outward around the shaft 3 against the pressure and fitting it onto the outer circumferential surface of a conduit P such as a water pipe or faucet pipe, the inner parts of both holders 1 and 1 are opened by the pressing force of the spring 4 mentioned above. The circumferential surface can be fixed in a state in which it is in close contact with the outer circumferential surface of the conduit P by pressure contact.

Further, since the spring 4 is used to tightly fix the device as described above, it is possible to attach the device to conduits having slightly different outer diameters.

For example, conduits for conducting domestic, agricultural, or industrial water are generally hard vinyl chloride pipes made of non-magnetic material with an outer diameter of about 20 to 23 mm, and soft rubber or resin hoses. The faucet pipe to be connected is often a metal pipe with an outer diameter of about 17 mm made of non-magnetic material such as a copper-zinc alloy. The radius of curvature of the surface is approximately 10.5 mm (diameter approximately
21 mm), and the circumferential length of each holder 1 is slightly shorter than a semicircle, that is, when both holders 1 are opened in a perfect circle, the end opposite to the shaft 3 is at the center angle. By configuring them so that they are separated by about 30 degrees, it is possible to attach them to P1 to P3, which have various outside diameter dimensions, as shown in FIGS. 4a to 4c, for example. Figure 4a shows the state in which it is attached to a soft rubber hose with a diameter of 23 mm, figure b shows the state in which it is attached to a hard vinyl chloride pipe with a diameter of 20 mm, and figure 4 c shows the state in which it is attached to a faucet pipe P3 of a water faucet with a diameter of 17 mm. show.

In addition, in the illustrated example, an inclined surface 1 is formed on the outer edge of the end of each holder 1, 1 on the side opposite to the shaft 3 in the circumferential direction.
b is formed, and especially when installed in a small diameter conduit P3 as shown in FIG.
It can be easily removed by placing your finger on b and opening it.

As mentioned above, both the holders 1, 1 are always biased to rotate in the closing direction by the spring 4, and if a particularly strong spring is used, the holders 1, 1 may be rotated against the spring. It is preferable to provide an opening operation member as necessary so that it can be opened easily.

In the illustrated example, the operating member is provided with a pair of levers 5, 5 made by bending stainless steel wire into a substantially U-shape as shown in FIG. Figure 5 shows the chain line 5
It opens as shown a', fits into the small hole 1c formed in the end face of each holder 1, and rotates toward the shaft 3 as shown by the chain line 5' in the figure. In this state, by pinching both levers 5, 5, both holders 1, 1 open as shown in FIG. 6, and can be easily attached to the conduit P. Note that after the holders 1, 1 are attached to the conduit P, both levers 5, 5 are removed from the holders 1, 1 in the reverse order as described above. In the figure, reference numeral 1d denotes a locking protrusion for preventing both ends of the lever 5 from opening outward when the lever 5 is used to open both the holding bodies 1,1.

[Effect of idea]

As explained above, the fluid magnetic processing tool of the present invention has a pair of semi-cylindrical magnet holders 1, 1 each containing a permanent magnet 2 facing each other and connected in an openable and closable manner by a shaft 3, and a spring 4 and both the above holding bodies 1,1
Because it is always biased to rotate in the closing direction, it can be easily and securely attached to the outer circumferential surface of a conduit P such as a water pipe, and it can also be attached to various types of conduits with slightly different outer diameters. This has the effect of providing a processing tool.
