Description

  The present invention relates to a magnetic health device for promoting health utilizing an alternating magnetic field generated from an electromagnetic coil by energization of an alternating current.

  It is known that applying magnetism to the human body has an effect of stimulating the subcutaneous tissue to promote blood circulation and activate muscles to recover symptoms such as stiff shoulders. For this reason, various types of magnetic health appliances have been proposed, but those using electromagnetic coils in addition to permanent magnets as magnetism generating means are known (see Patent Document 1).

  6 and 7, in a magnetic field generating treatment device in which an electromagnetic coil composed of a laminated iron core 21 and a coil 24 is accommodated in the case 20, a laminated iron core formed by laminating a plurality of silicon steel plates. 21 is formed by integrally projecting magnetic field concentration projections 22 on the end face of the lamination, and the coil bobbin 23 is formed by winding a coil 24 around the peripheral surface of a spool having flanges 25 at both ends. 25 is formed to a thickness that matches the height of the protrusion 22 of the laminated iron core 21, and the magnetic field generating treatment tool in which the coil bobbin 23 is fitted on the laminated iron core so that the flange 25 corresponds to the position of the protrusion 22. Is described.

  This magnetic field generation treatment device is wound around and fixed to the site where the magnetic field is radiated toward the site where pain or stiffness occurs in the body, and when the power is turned on, each coil of each magnetic field generator is energized, and the laminated iron core The superimposed magnetic flux of each coil is generated from the end face of each leg portion, in particular from the protrusion. Along with this, heat is generated from the iron core and each coil, and this heat is transmitted to the pain and stiffness through the case to promote blood circulation.

  In the conventional magnetic field generating treatment device, when trying to increase the magnetic flux density, the laminated iron core formed by laminating the silicon steel plates becomes large, so the case becomes large, and when the size is easy to handle, a large magnetic flux density is obtained. There was no problem. In addition, since it cannot be used at a low voltage due to the magnetic flux density, many safety measures are required.

  In addition, since the laminated iron core of the electromagnetic coil is formed by laminating and laminating silicon steel plates on which protrusions are formed, it takes time to manufacture the iron core. In addition, in order to generate vibration and obtain a massage effect, there was a method of weighting the laminated iron core and vibrating the laminated iron core itself with an electric current or adding a vibration plate part. The former is weight, the latter is a diaphragm There has been a problem of failure of component slippage.

  Furthermore, in the conventional magnetic field generating treatment device, the movement of the connecting portion is only uniaxial bending, so that it may not fit depending on the location of the body.

  Therefore, the present invention provides a high magnetic flux density and can be used at a low voltage. The connecting portion can be rotated about two axes so that the body can be freely fitted to move freely, and an electromagnetic coil can be easily manufactured. A magnetic health device is provided.

  In the magnetic health device of the present invention, a plurality of synthetic resin cases are connected to each other so as to be able to be bent and twisted biaxially rotated by a coupler, and the synthetic resin case has one side in the longitudinal direction formed in a straight line, Each side of the synthetic resin case has a bobbin around which a coil for passing an alternating current is wound, and an outer ferrite core is placed on both sides of the coil. Features.

  In the above configuration, a ferrite plate is disposed on the inner surface of the resin lid that covers the upper surface of the bobbin so as to be opposed to the ferrite core. Also, the arc-shaped side surfaces of the two magnetic health devices are formed on the arc-shaped side surface and / or the linearly-formed side surface, or the linear shape is formed. It is characterized in that a magnet that is magnetically attached by arranging the surfaces on the opposite sides facing each other is provided. The upper portion of the ferrite core may have a tapered shape.

  Since the present invention uses a ferrite core that is easy to process, it can be easily processed into the best shape that allows the magnetic force to escape, and as a result, the magnetic field lines can be concentrated and the magnetic flux density can be increased. It was. By using a ferrite core, an alternating magnetic force can be generated at a lower voltage than a conventional laminated iron core of a silicon steel sheet, and a high magnetic flux density can be obtained. In addition, the use of a ferrite core has made the case thinner and more compact, making it possible to reduce the size of the case. Further, the size reduction has made it possible to reduce the weight of conventional cases.

  In the present invention, it is connected to bendable and torsionally rotatable, is rotated in two axial directions, and is formed in a circular arc shape in which one side in the longitudinal direction is recessed inward, so that it reliably contacts a site such as stiffness or pain It became easy to do. Further, by arranging the arcuate surfaces of the magnetic health device so as to face each other, it is possible to form an annulus and to apply magnetism to the entire neck. On the other hand, magnetism can be applied to the back and waist by arranging the straight surfaces facing each other.

  According to the present invention, a ferrite plate is arranged on the inner surface of a resin lid on the upper surface of a bobbin so as to be opposed to the ferrite core and spaced to vibrate, thereby obtaining a massage effect without failure of the vibration plate components. It became possible.

  Embodiments of the present invention will be described with reference to the drawings.

  1 and 2, each of a plurality of synthetic resin cases 1 is connected by a coupler 2 so as to be able to bend in the longitudinal direction and to be twisted in two axes. Since it is flexible by allowing two-axis rotation, it can be easily fitted to the body and can be treated by applying magnetism in three dimensions.

  The synthetic resin case 1 is formed in a circular arc shape in which one side in the longitudinal direction is linearly formed and the other side is recessed inward. By forming it in an arc shape, the magnetic health device can be brought into contact along the neck. The number of the synthetic resin cases 1 to be connected is preferably such that the synthetic resin cases 1 at both ends are placed on the shoulders as shown in FIG.

  As another form of use, by providing a magnet M for magnetically adhering the arcuate surfaces of two magnetic health appliances facing each other at the end of the arcuate surface of the synthetic resin case As shown in FIG. 5, magnetism can be applied to the entire neck. Alternatively, the synthetic resin case 1 may be made of a synthetic resin by providing a magnet M on which the linear surfaces of the two magnetic health appliances can be opposed to each other and magnetically attached to the linear surface on one side of the synthetic resin case 1. Since the linear contact portion of the case 1 can be magnetized to increase the contact area to the body and the area where the magnetic lines of force act can be expanded, the magnetism acts on the back and around the waist as shown in FIG. It becomes possible.

  Each synthetic resin case 1 includes an electromagnetic coil fixing case 4 for fixing the electromagnetic coil 3 and a case lid 5 covering the electromagnetic coil fixing case 4. A coupler 2 that connects adjacent electromagnetic coil fixing cases 4 is rotatably supported by a rotating cylinder 6 that is held by one electromagnetic coil fixing case 4 and the other electromagnetic coil fixing case 4. Is held by a rotating cylinder 7 orthogonal to the rotating cylinder 6. With this structure, the adjacent synthetic resin cases 1 can be bent and twisted, and can be freely bent three-dimensionally by biaxial rotation, so that the magnetic health device can be fitted to the affected area. In both rotary cylinders 6 and 7, lead wires 8 for electric power and control are inserted to electrically connect the electromagnetic coils 3 to each other. Electricity and a signal are input to the lead wire 8 from an electric cord line 9 connected to a power source and an operating device. Since the lead wire 8 is inserted through the rotary cylinders 6 and 7, there is no fear of bending.

  As shown in FIGS. 2 and 3, the electromagnetic coil 3 is housed and fixed in each electromagnetic coil fixing case 4. The electromagnetic coil 3 radiates a magnetic field toward the case lid 5 side. In the electromagnetic coil 3, a coil 12 wound around a bobbin 11 is provided on a ferrite core 10, and an alternating current is passed through the coil 12 to generate an alternating magnetic field. In the ferrite core, an outer ferrite core 13 is arranged on both sides of the center core around which the coil is wound and the coil 12 wound around the ferrite core 10, and the ferrite core 10 and the bases 14 of the outer cores 13 on both sides are connected and integrated. ing. Ferrite is easy to process, and can be easily formed into the best shape to dissipate magnetic force, and the magnetic flux density can be increased by forming the tip of the ferrite core into a tapered shape. Further, the magnetic flux density can be increased by disposing the ferrite core 10 and the outer ferrite core 13 outside the coil.

  The surface of the electromagnetic coil 3 is covered with a resin lid 15. If the ferrite plate 16 is disposed on the inner surface of the lid so as to face the ferrite core 10 and spaced apart, the ferrite disc 16 can be vibrated by an alternating current when the electromagnetic coil 3 is energized.

  In the magnetic health device of the present invention, the magnetic health device is first wound around the neck and fixed so that the case hits against a site where stiffness or pain occurs in the body. Next, when the power is turned on, the electromagnetic coil of each case is energized, and the magnetic flux of each coil is generated. Along with this, heat is generated from the ferrite core and the coil, and this heat is transmitted to the case. In this case, the temperature is controlled by a thermistor so that excessive heat generation does not occur.

  Table 1 shows a comparison between a magnetic health device of the present invention using a ferrite core and a conventional magnetic field generating treatment device using a laminated core of silicon steel plates.

  The magnetic health device of the present invention has been able to generate an alternating magnetic force of 90 mT, which has not been generated at a conventional low voltage, by greatly reducing the conventional AC 100 V to a low voltage of 30 VAC. In addition, the thickness was reduced, and it was possible to reduce the size and weight.
