Description

The present invention relates to a rotating magnetic therapy device. In particular, the present invention relates to a rotating magnetic therapy device (rotating magnetic therapy device) that has a simple device structure, is low in cost, and makes it easy to grasp the location where the magnetism hits.

Magnetic fields are known to affect the human body, other living things, water, and chemical agents. The magnetic field is applied to magnetic field therapy (magnetic therapy) to local parts of the human body (see, for example, Patent Document 1 and Patent Document 2). Patent Document 1 discloses a magnetic therapy device that can enhance the magnetic therapy effect by preventing leakage of magnetic lines of force and having a structure in which the upward emission height of magnetic lines of force and the strength of magnetic lines of force are maximized. . Furthermore, Patent Document 2 discloses a compact rotating magnetic therapy device that can generate a varying magnetic field over a wide range.

FIG. 1 shows the magnetic therapy device disclosed in Patent Document 1. The magnetic therapy device 1000 shown in FIG. 1 is a magnetic therapy device that rotates at low speed (low-speed rotation magnetic therapy device). This magnetic therapy device 1000 is composed of two or more even number of ferromagnetic bodies 101 and a magnetically conductive rotating arm 102. Each ferromagnetic body 101 is mounted and fixed symmetrically on the same surface of the magnetically conductive rotating arm 102. The magnetic poles of the free surfaces of the two symmetrical ferromagnetic bodies 101 are different (S and N). The area of the free surface of the ferromagnetic material 101 is larger than the area of the connecting surface. Further, the cross section of the ferromagnetic material 101 has a geometric shape with no corners. The magnetically conductive rotating arm 102 and the ferromagnetic body 101 are rotated by an electric device 104 .

In the magnetic therapy device 1000 of FIG. 1, the cross section of the ferromagnetic material 101 has a geometric shape with no corners, so that leakage of magnetic lines of force and the amount of ferromagnetic material used can be reduced. Furthermore, since the magnetic field strength in a predetermined direction is increased, magnetic lines of force are prevented from interfering with other electronic products. Furthermore, since the area of the free surface of the ferromagnetic material 101 is larger than the area of the connecting surface, the lines of magnetic force are emitted from the free surface of one ferromagnetic material 101 and absorbed from the free surface of the other ferromagnetic material 101. Ru. Then, the lines of magnetic force inside the ferromagnetic body pass from one ferromagnetic body 101 through the magnetically guiding rotating arm 102 and enter the other ferromagnetic body 101 . This causes the lines of magnetic force to concentrate and the magnetic field strength to reach its maximum. Furthermore, due to the edge effect of the magnetic field, the emission height above the lines of magnetic force becomes higher and the magnetic flux density becomes higher, so that the magnetic treatment effect can be enhanced. In addition, the electric device 104 can rotate the magnetically conductive rotary arm 102 and the ferromagnetic body 101 at low speed to perform magnetic treatment using a strong magnetic field.

Further, a magnetic therapy device disclosed in Patent Document 2 is shown in FIG. 2(a) is a top view of the magnetic therapy device 1100 of Patent Document 2, and FIG. 2(b) is a sectional view of the magnetic therapy device 1100. The magnetic therapy device 1100 shown in FIG. 2 is used by being attached to the skin 190 of a human body. The magnetic therapy device 1100 includes a housing 120. The housing 120 is provided with a switch 110 and a USB terminal 130. Furthermore, a battery 110 is housed inside the housing 120. The housing 120 has a bottom surface, and the bottom surface is a part that comes into direct or indirect contact with the skin 190 when the magnetic therapy device 1100 is attached to the skin 190. Further, a treatment magnet section 130 is housed in the housing 120, and the treatment magnet section 130 is supported by a support stand 140. The support stand 140 is rotationally driven by a rotation drive device 150 around a rotation shaft 160 extending substantially perpendicular to the bottom surface.

In the case of a regular adhesive magnetic therapy device, the magnet is fixed to a specific position relative to the skin, and the magnetic field is fixed, resulting in so-called "hanging" and reducing the magnetic therapy effect. Furthermore, when the rotating magnetic therapy device is used by being attached to the user's skin, it is difficult to stably attach and operate the rotating magnetic therapy device to the user's skin. Under such circumstances, the magnetic therapy device 1100 of FIG. 2 can generate a varying magnetic field over a wide range with a compact configuration. To explain further, when the rotating magnetic therapy device 1100 is attached to the skin 190 of a human body, the support base 140 rotates in a plane substantially parallel to the bottom surface of the housing 120, thereby causing fluctuations over a wide range of the skin 190. A magnetic field can be generated.

It seems that the magnetic therapy device 1000 shown in FIG. 1 is being considered for use in a relatively large or medium-sized device (for example, in the form of a chair) (see FIGS. 6 and 7 of Patent Document 1). You may want to use a small, handy type that you can easily use anywhere. In addition, in some forms such as chairs, it is relatively easy to tell which direction the magnetism (or lines of magnetic force) is facing, but since magnetism is invisible, small hand-held magnetic therapy devices do not allow you to tell which direction the magnetism (or lines of magnetic force) is facing. Or it may not be immediately obvious in which region magnetism (magnetic lines of force, magnetic flow) is occurring. In other words, a user wants to apply magnetism to a predetermined area (such as an affected area), but it is often difficult to tell whether or not it is hitting that area. The inventor of this application has been earnestly considering whether it is possible to make it easier to understand.

Furthermore, although the magnetic therapy device 1100 shown in FIG. 2 can be fixed to a specific position on the skin, it is difficult to fix the magnetic therapy device 1100 to the skin at that location to which you want to apply magnetism. It's not necessarily possible. That is, the magnetic therapy device 1100 shown in FIG. 2 can only be used in areas where it can be fixed to the skin.

Under such circumstances, the inventor of the present application has been diligently considering whether it is possible to create a rotating magnetic therapy device that is relatively compact, has a relatively simple device configuration, and makes it easy to grasp the location where the magnetic field hits. This led to the present invention. The present invention has been made in view of these points, and its main purpose is to provide a rotating magnetic therapy device that makes it easy to grasp the location where the magnetism hits.

In the following drawings, in order to simplify the explanation, the same reference numerals are given to members and parts that have the same function, and overlapping explanations may be omitted or simplified. Further, although the dimensional relationships (length, width, thickness, etc.) in each figure basically satisfy the dimensional relationships, they may not necessarily accurately reflect the actual dimensional relationships.

Additionally, matters other than those specifically mentioned in this specification that are necessary for implementing the present invention can be understood as matters designed by those skilled in the art based on the prior art in the field. The present invention can be implemented based on the contents disclosed in this specification and drawings and common general technical knowledge in the field. In addition, the present invention is not limited to the following embodiments.

FIG. 3 is a front view showing the configuration of the rotating magnetic therapy device 100 according to the embodiment of the present invention. FIG. 4 is a rear view showing the configuration of the rotating magnetic therapy device 100 of this embodiment. 5 and 6 are a side view and a perspective view of the rotating magnetic therapy device 100 being held in the hand.

As shown in FIG. 3, the rotating magnetic therapy device 100 of this embodiment includes a plurality of magnets (permanent magnets) 10 (11, 12), and rotates the plurality of permanent magnets 10 (11, 12). It is equipped with a mechanism that generates a fluctuating magnetic field. The rotating magnetic therapy device 100 of this embodiment includes a plurality of magnets 10 (11, 12), a disc member 20 that fixes the magnets 10 (11, 12), and an electric motor 35 that rotates the disc member 20. It is comprised of a fan 22 connected to a disc member 20 and a housing 40 housing a battery (45) that supplies power to an electric motor 35.

In the rotating magnetic therapy device 100 of this embodiment, the plurality of magnets 10 are the first magnet 11 and the second magnet 12, and are arranged on the disk member 20. The first magnet 11 is a permanent magnet with a first polarity (here, S pole) on the front surface and a second polarity (here, N pole) on the back surface. The second magnet 12 is a permanent magnet with a second polarity (here, N pole) on the front surface and a first polarity (here, S pole) on the back surface. Contrary to what is illustrated, the first polarity may be the north pole and the second polarity may be the south pole.

As the magnets 10 (11, 12) of this embodiment, rare earth permanent magnets (for example, neodymium magnets or Samagoba magnets) can be used. The first magnet 11 and the second magnet of this embodiment may have, for example, 200 millitesla (magnetic flux density: mT) to 510 millitesla (mT). In the illustrated example, the first magnet 11 and the second magnet are neodymium magnets. Further, as the magnets 10 (11, 12) of this embodiment, it is also possible to use magnets other than rare earth permanent magnets (for example, ferrite magnets), depending on the magnitude of the fluctuating magnetic field that is desired to be generated. Note that rare earth permanent magnets (for example, neodymium magnets) have a higher upper limit of magnetic flux density than ferrite magnets (for example, neodymium magnets of 500 mT or more). In a preferred example of this embodiment, the first magnet 11 is a disc-shaped neodymium magnet with a diameter of 10 mm, a thickness of 5 mm, and a capacity of 416 mT. The second magnet 12 is a disc-shaped neodymium magnet with a diameter of 20 mm, a thickness of 5 mm, and a capacity of 261 mT (or a disc-shaped neodymium magnet with a diameter of 15 mm, a thickness of 5 mm, and a capacity of 315 mT).

The disk member 20 that fixes the first magnet 11 and the second magnet 12 is made of resin. Note that the disk member 20 may be constructed from other materials (for example, wood, ceramic, etc.), but when constructed from resin, it has characteristics such as being lightweight and difficult to break (or being inexpensive and suitable for mass production). It is convenient. The disc member 20 of this embodiment has a diameter of, for example, 2 cm to 5 cm (the one shown is 3 cm), but may have other dimensions. The back surface of the first magnet 11 and the back surface of the second magnet 12 are fixed to the surface of the disk member 20. In this embodiment, the first magnet 11 and the second magnet 12 are fixed (adhered) to the disc member 20 with an adhesive. Note that the first magnet 11 and the second magnet 12 may be fixed to the disk member 20 by a method other than adhesive (for example, fitting, screwing, taping, etc.).

In the configuration of this embodiment, the first magnet 11 is arranged at the center of the disk member 20 (around the rotational center point). The second magnet 12 is arranged closer to the outer edge of the disk member 20 than to the center. In the configuration of this embodiment, one first magnet 11 is provided, and a plurality of second magnets 12 are provided. In the illustrated example, two second magnets 12 are provided. Further, the diameter of the first magnet 11 is smaller than the diameter of the second magnet 12. By making the size (diameter) of the first magnet 11 located at the center smaller than the size (diameter) of the second magnet 12 located on the outer periphery, an effect can be obtained that the whole can be arranged compactly. I can do it.

Further, the diameter of the first magnet 11 of this embodiment is 0.5 cm to 2 cm (1 cm in the illustrated case), and the diameter of the first magnet 11 is 0.5 cm to 3 cm (1.5 cm in the illustrated case). However, other dimensions may also be used. In the configuration example of this embodiment, the diameter of the second magnet 12 is set to be 1.5 times (or more) than the diameter of the first magnet 11. Further, the outer edge (side surface) of the second magnet 12 is arranged so as to be in close contact with the outer edge (side surface) of the first magnet 11 . This close contact is achieved by magnetic force (and also by adhesive). Note that an arrangement may be adopted in which a gap is created between the first magnet 11 and the second magnet 12. In the configuration example of this embodiment, a part (outer part) of the second magnet 12 is arranged so as to protrude from the disk member 20.

As shown in FIGS. 3 to 5, an electric motor (electric motor) 35 is provided on the back side of the disc member 20. As shown in FIGS. The electric motor 35 rotates when electricity (direct current, power) is supplied to a coil. The rotation output shaft of the electric motor 35 is connected to the disc member 20, and therefore, when the electric motor 35 rotates, the disc member 20 to which the first magnet 11 and the second magnet 12 are fixed rotates. The rotation speed of the disc member 20 (or the fan 22) is, for example, 2000 times/min or more or 7000 times/min or less, and in a preferred example, 2200 to 6710 times/min. The rotation speed can be measured using, for example, a non-contact tachometer (mini non-contact tachometer UT373 manufactured by UNI-T).

In the configuration of this embodiment, a battery 45 that supplies power to the electric motor 35 is housed within the casing 40 . The battery 45 of this embodiment is a rechargeable secondary battery, specifically a lithium ion battery (rechargeable lithium ion battery). The lithium ion battery 45 in this example has characteristics of 3.7V, 1200mAh, and 4.44Wh. Note that the battery 45 of this embodiment may be a primary battery (dry battery) instead of a secondary battery.

In the configuration of this embodiment, a fan (blade portion) 22 is connected to the disk member 20. In the illustrated configuration example, the fan 22 is formed to extend on the side surface of the disc member 20. In this example, the number of blades of the fan 22 is six, but the number of blades is not limited to this number. In the configuration of this embodiment, the disc member 20 and the fan 22 are integrally molded parts, and are made of the same type of resin material. Note that the disk member 20 and the fan 22 may be made separately and then connected, but integrally molded parts are more advantageous in terms of manufacturing cost and strength. .

Furthermore, in this embodiment, an upper cover 30 that covers the fan 22 is provided. In the illustrated example, a protection member 32 that protects fingers and the like from rotation of the fan 22 is formed on the upper cover 30 . In the illustrated example, the protection members 32 are a plurality of strip-shaped members arranged at equal intervals. In addition, in the structure of this embodiment, the protection member 32 is arrange|positioned at the outer peripheral part, but it may have the structure extended so that it may cover the disk member 20 (or center part).

As shown in FIG. 4, the housing portion 40 of this embodiment is connected to the back surface portion 33 of the upper cover 30 through the connecting portion 34 (upper and lower member connecting portion). In the configuration of this embodiment, the housing main body part 42 that constitutes the housing part 40 has a cylindrical shape (here, a cylindrical shape). A connecting portion 34 extends from the housing body portion 42 and is connected to the back surface portion 33. Further, in the configuration of this embodiment, the protection member 32 extends from the back surface portion 33. An electric motor 35 is disposed on the front side of the back section 33. In other words, the electric motor 35 is located between the back portion 33 and the disk member 20.

Furthermore, the casing section 40 of this embodiment has a shape (the casing main body section 42) that can be grasped (or held) by a user's hand. The housing section 40 (the housing main body section 42) is provided with a switch section 41 for turning on/off the drive of the electric motor 35. The switch unit 41 of this embodiment is designed to not only turn the electric motor 35 on and off, but also change the rotational strength in multiple stages (for example, weak, medium, and strong). Specifically, by pressing the switch unit 41, the electric motor 35 can be changed from off to on (weak), medium, strong, and off. For example, a weak (low speed) rotation speed is approximately 2200 to 2400 times/min, a medium (medium speed) rotation speed is approximately 2400 to 4600 times/minute, and a strong (high speed) rotation speed is: Approximately 3100 to 6800 times/min.

Further, the housing portion 40 (the housing main body portion 42) is provided with a terminal 43 for charging a battery (lithium ion battery) 45. In the illustrated example, the charging terminal 43 is a USB terminal, and a terminal of a charging cable (USB cable) 46 can be connected to the USB terminal 43. By connecting the charging cable (USB cable) 46 to another power source, the battery 45 of this embodiment can be charged, and the rotating magnetic therapy device 100 of this embodiment (or electric motor 35) can be driven.

Furthermore, a control circuit (circuit board) for charging the battery 45 (internal power source) and driving the electric motor 35 is arranged inside the casing section 40 (casing main body section 42). Further, wiring from the battery 45 (or the control circuit) passes through the interior of the connecting portion 34 (upper and lower member connecting portion) and is electrically connected to the electric motor 35. Although the casing section 40 (casing main body section 42) of this embodiment is made of resin, it may be made of other materials. Note that a strap 48 for preventing attachment and detachment is provided on a part of the casing section 40 (the casing main body section 42).

As shown in FIGS. 5 and 6, the forward direction (arrow 90) of the disc member 20 on which the magnets 10 (11, 12) are arranged is the fluctuating magnetic field (magnets 10, 11, 12)) is the direction in which the fluctuating magnetic field due to the rotation of the fan 22) is directed, and this is the direction in which the wind from the fan 22 is directed. That is, in the illustrated example, the direction from the back surface (N pole) to the front surface (S pole) of the first magnet 11 is the direction of arrow 99 (forward direction).

The magnetic therapy device 1000 shown in FIG. 1 and the rotating magnetic therapy device 100 of this embodiment will be described with reference to FIGS. 7 and 8. FIG. 7 is a schematic diagram illustrating the operation of the magnetic therapy device 1000 shown in FIG. 1, and FIG. 8 is a schematic diagram illustrating the operation of the rotating magnetic therapy device 100 of this embodiment.

As shown in FIG. 7, in the case of the magnetic therapy device 1000, the rotation (S) of the ferromagnetic material 101 supported by the magnetically conductive rotating arm 102 generates a fluctuating magnetic field, which hits the human skin 190 and exerts an influence. (Specifically, treat the affected area). In the case of the rotating magnetic therapy device 100 of this embodiment, as the magnets 10 (11, 12) rotate (S), a fluctuating magnetic field is generated, which hits and affects the human skin 190 (arrow 90), The fan 22 rotates (S) and its wind (W) hits the skin 190. Therefore, the affected area (190) can be treated by the influence of the fluctuating magnetic field, and it can be immediately determined whether the fluctuating magnetic field is hitting the affected area due to the wind (W).

As described above, according to the rotating magnetic therapy device 100 of the present embodiment, while the disk member 20 to which the first magnet 11 and the second magnet 12 are fixed is rotated by the electric motor 35, the fan connected to the disk member 20 is rotated by the electric motor 35. 22 can be rotated. Therefore, by rotating the first magnet 11 and the second magnet 12, a fluctuating magnetic field can be generated, and the part (affected area (or magnetic irradiation part)) that is hit by the fluctuating magnetic field by the wind (W) generated by the rotation of the fan 22. 190) can be blown with wind (W). As a result, it is possible to realize the rotating magnetic therapy device 100 in which it is easy to grasp the location (190) where the magnetism hits. In addition, the rotating magnetic therapy device 100 of the present embodiment is compact, and the user (or practitioner) can easily hold it in his/her hand and apply the generated magnetism (fluctuation magnetism) to a desired location (190). be. In this respect, it is significantly different from the rotary magnetic therapy instrument 1100 (see FIG. 2), which can only be used by being attached to (contacting) the skin.

In the rotating magnetic therapy device 100 of this embodiment, by fixing the magnets 10 (11, 12) to the disk member 20 (rotor) and rotating them, a magnetic flux is formed in front of the magnet 10, and the formed magnetic flux The displacement current associated with magnetic flux fluctuations also works to heal the affected area 190. In the case of the rotating magnetic therapy device 100 of this embodiment, compared to the type that is attached to the skin, the magnetic flux can be sent far, and the fluctuation of the magnetic flux is large, so that the wind and the magnetic flux are directed in the direction (arrow 90). , it is easy to match the magnetic flux to the affected area. Since you can use a handheld electric fan (mini fan), you can reduce manufacturing costs, you can easily adjust the rotation speed (low, medium, strong), and you have the advantage of quiet hand vibration. In addition, the rotating magnetic therapy device 100 of this embodiment is easy to handle.

By using the rotating magnetic therapy device (displacement current generator) 100 of this embodiment, a displacement current can be generated in the affected area (160) and energy can be supplied thereto. The rotating magnetic therapy device (displacement current generator) 100 of this embodiment is particularly effective in treating sprains, stiff shoulders, and the like. In addition, natural recovery from fatigue is expected after fatigue, but since displacement current itself has the power of recovery, it is effective as an auxiliary recovery device, and can be used to recover from sprains, etc. It is effective in recovering from the pain that occurs. Even if the body shape has been deformed due to injury, it can be used to aid recovery over time, and can also be used to assist in rehabilitation after surgery. It can also have effects similar to acupuncture. Additionally, since the varying magnetic field passes through the body, affected areas within the body can also be healed. Since it is a displacement current (generated electricity) caused by a fluctuating field, it has the potential to be effective against bacteria and cancer. It is also expected to be used as an aid in the treatment of diabetes (type 2) and cataracts.

The rotating magnetic therapy device (displacement current generator) 100 of this embodiment uses a strong magnet 10 (neodymium magnet) to generate displacement current to a practical level even if the device has a simple configuration. can be done. Even with a device having a simple configuration, it is possible to generate an appropriate rotational speed, obtain sufficient variation in magnetic flux, and obtain a displacement current up to a practical level. Thus, the generated magnetic flux and the displacement current accompanying the magnetic flux fluctuation work to heal (or support healing) the affected area 190.

The rotating magnetic therapy device (displacement current generator) 100 of this embodiment can be modified as follows. 9 and 10 show a modified example of the rotating magnetic therapy device 100 of this embodiment.

In a modified example of this embodiment, a plurality of second magnets 12 are arranged at equal intervals along the outer periphery of the first magnet 11 at the center. In the configuration shown in FIG. 9, three second magnets 12 (12a, 12b, 12c) are arranged. In this way, instead of two, three (or more) second magnets 12 may be arranged. In the example shown in Figure 9, they are arranged at equal intervals (in an equilateral triangle), but if the arrangement is slightly off-centered and does not affect the effectiveness of the treatment, then that may be adopted. I don't mind. The configuration shown in FIG. 9 shows an example in which the surface of the first magnet 11 is the S pole and the surface of the second magnet 12 is the N pole (contrary to the configuration example shown in FIG. 3). There is.

Furthermore, in the configuration shown in FIG. 10, four second magnets 12 (12a, 12b, 12c, 12d) are arranged. The configuration example shown in FIG. 10 has the advantage that it is easier to arrange the second magnets 12 because the second magnets 12 are arranged in a cross pattern.

Other modifications can be constructed as follows. Note that the north pole and the south pole are interchangeable, and only one pole is shown. (1) Three magnets 10 are lined up in a row and arranged so as to have N pole, S pole, and N pole (similar example to that shown in FIG. 3; a configuration example in which they are arranged in a row). (2) Arrange four magnets 10. Arranged so that there is one in the center (S pole) and three around (N pole) (similar to what is shown in Figure 9). (3) Arrange five magnets 10. Arranged so that there is one in the center (S pole) and four around (N pole) (similar to what is shown in Figure 10).

Furthermore, when the rotating magnetic therapy device (displacement current generator) 100 of this embodiment is used near the affected area (190) of the human body, modifications as shown in FIG. 11 may be made.

FIG. 11 shows an example of the arrangement of the magnets 10 (11, 12) in the rotating magnetic therapy device 100 as a modified example of the present embodiment. When used close to the affected area (190) of the human body, it is often irradiated at a pinpoint (applying a fluctuating magnetic field) rather than over a wide area, so as shown in Figure 11, the disk member The first magnet 11 and the second magnet 12 can be arranged adjacent to each other in the center of the magnet 20 . In FIG. 11, magnets (neodymium magnets) 10 of the same size (same type) are used. Note that even in the configuration examples shown in FIGS. 3, 9, and 10, magnets (neodymium magnets) 10 of the same size (same type) may be used.

When it is desired to apply a magnetic field over a wider range than in the configuration example shown in FIG. 11, the first magnet 11 and the second magnet 12 may be placed apart from each other as in the configuration example shown in FIG. In the example shown in FIG. 11, the first magnet 11 and the second magnet 12 are arranged at symmetrical positions with respect to the central axis (C) of the disk member 20.

Furthermore, as shown in FIGS. 13 to 15, a rotating magnetic therapy device 100 using one magnet 11 (10) may be used. FIG. 13 shows an example in which the magnet 11 (10) is arranged so that its center is located on the central axis (C) of the disk member 20. FIG. 14 shows an example in which a part (or outer edge) of the magnet 11 (10) is located on the central axis (C) of the disc member 20 (in other words, the central axis (C) of the disc member 20 is ) is an example in which the center of the magnet 10 is shifted). FIG. 15 shows an example in which the magnet 11 (10) is arranged so as not to be located in the region of the central axis (C) of the disk member 20.

In the configuration of the rotating magnetic therapy device (displacement current generator) 100 of this embodiment, the rotation speed affects the strength of the varying magnetic field. When the inventor of this application measured the rotation speed, the following results were obtained. In the configuration example shown in FIG. 13, when the first magnet 11 has a diameter of 15 mm, the weak (low speed) rotation speed is 2401 times/min, and the medium (medium speed) rotation speed is 3002 times/minute. Yes, and the high (high speed) rotation speed is 3303 times/min. In the configuration example shown in FIG. 3, when the first magnet 11 has a diameter of 10 mm and the second magnet 12 has a diameter of 15 mm, the low (low speed) rotation speed is 2421 times/min, and the medium (medium speed) rotation speed is 2421 times/min. The number of rotations is 2676 times/minute, and the high (high speed) rotation speed is 3180 times/minute. In the configuration example shown in FIG. 9, when the first magnet 11 has a diameter of 10 mm and the second magnet 12 has a diameter of 15 mm, the low (low speed) rotation speed is 2218 times/min, and the medium (medium speed) rotation speed is 2218 times/min. The number of rotations is 2456 times/minute, and the high (high speed) rotation speed is 2710 times/minute. In the configuration example shown in FIG. 10, when the first magnet 11 has a diameter of 10 mm and the second magnet 12 has a diameter of 15 mm, the low (low speed) rotation speed is 2236 times/min, and the medium (medium speed) rotation speed is 2236 times/min. The number of rotations is 4611 times/minute, and the high (high speed) rotation speed is 6710 times/minute. The configuration example shown in FIG. 10 exhibited the best rotation speed because the layout of the magnets 10 (11, 12) contributed well to rotation. In addition, the strength of the varying magnetic field can be increased due to the high rotational speed. In other words, even if the motor is the same, the rotational speed changes depending on the layout of the magnets, and the fluctuating magnetic field generated accordingly changes.

FIG. 16 is a front view showing the configuration of a magnetic therapy device (displacement current generator) 200 according to another embodiment of the present invention. FIG. 17 is a side view showing the configuration of the magnetic therapy device 200. The magnetic therapy device 200 of this embodiment is not a rotary type having the configuration shown in FIG. 3, but a vibrating type variable magnetic field generating device.

The magnetic therapy device 200 of this embodiment utilizes the structure of a vibrating electric toothbrush. The magnetic therapy device 200 includes a horizontal connection portion (left and right connection portions) 50 to which magnets 15 (15a, 15b) are fixed at both ends, an upper and lower connection portion 55 that fixes the horizontal connection portion (left and right connection portions) 50, and an upper and lower connection portion. The casing section 40 supports the section 55.

The center portion of the horizontal connection portion 50 is connected to the tip portion of the vertical connection portion 55 . The connection between the vertical connection part 55 and the horizontal connection part 50 can be performed using an adhesive, but may also be performed by other means (for example, fitting, screwing, fusing, tape fixing, etc.). Further, it is also possible to use a member in which the upper and lower connecting portions 55 and the horizontal connecting portions 50 are integrally molded. A first magnet 15a with an S pole on the inside and a N pole on the outside, and a second magnet 15b with an N pole on the inside and an S pole on the outside are provided at both ends of the horizontal connection part 50. Note that the S and N poles may be reversed. The magnets 10 (15a, 15b) can be connected to both ends of the horizontal connecting portion 50 using an adhesive, but may also be connected by other means (for example, fitting, tape fixing, etc.).

A vibration generator (an electric motor or a piezoelectric vibrator that generates vibrations) and a battery (a dry battery (primary battery) or a secondary battery) are built into the housing 40. Note that the casing 40 may not have a built-in battery and may be a system in which electricity (power) is supplied from an outlet. The vibration generator can generate a frequency (sonic vibration) of, for example, 200 to 300 Hz. Due to this vibration, the horizontal connecting portion 50 and the horizontal connecting portion 50 vibrate, and the magnets 10 (15a, 15b) fixed to the horizontal connecting portion 50 vibrate, thereby generating a fluctuating magnetic field.

The casing main body 42 constituting the casing 40 has a cylindrical shape (substantially cylindrical shape) and can be held (held) by hand. The housing body section 42 is provided with a switch section 41 that can turn on and off the vibration. It is also possible to configure the vibration frequency to change from strong to medium to weak depending on the operation (pressing operation) of the switch section 41.

FIG. 18 is a schematic diagram illustrating the operation of the vibrating magnetic therapy device 200 of this embodiment. When the horizontal connecting portion 50' vibrates, the first magnet 15a and the second magnet 15b vibrate, thereby generating a displacement magnetic field. By applying the displacement magnetic field to the affected area 190', a displacement current is generated in the affected area 190', and treatment (or treatment assistance) is performed using the displacement current. The frequency of this configuration example (T-shaped vibrating magnetic therapy device 200) is, for example, 360 RPM (frequency of vibrations per minute).

FIG. 19 is a front view showing the configuration of a magnetic therapy device (displacement current generator) 210 according to another embodiment of the present invention, and FIG. 20 is a side view showing the configuration of the magnetic therapy device 210. The magnetic therapy device 210 of this embodiment is also a vibrating type variable magnetic field generator similar to the one shown in FIG. 16, and has one magnet 15 (10) compared to the one shown in FIG. 16. different. In the magnetic therapy device (displacement current generator) 210, the magnet 15 (10) also vibrates, thereby generating a displacement magnetic field. By applying the displacement magnetic field to the affected area 190', a displacement current is generated in the affected area 190', and treatment (or treatment assistance) is performed using the displacement current. The frequency of this configuration example (vibrating magnetic therapy device 210) is, for example, 1365 RPM (frequency of vibrations per minute).

Although the present invention has been described above using preferred embodiments, such description is not a limitation, and of course, various modifications are possible. For example, in the configuration of this embodiment, the disk member 20 that supports the magnets 10 (11, 12) is described as being circular, but if the magnets 10 (11, 12) can be rotated, it is not necessarily geometrically shaped. Instead of being circular in the sense of the term, the disc member 20 may have a shape such as a regular polyhedron (such as a regular hexagon or a regular octagon), for example. However, since the disk member 20 is a rotating body, it is preferable that the disk member 20 has a neat circular shape. In addition, although the magnet 10 has been described as having a circular (disk-like) structure, it may also be rectangular or rectangular. However, since it is rotated on the disk member 20, a circular shape without corners is often preferable. Further, although the fan 22 is shown extending from the side surface of the disc member 20, the fan 22 may be constructed separately from the disc member 20 (for example, the configuration shown in FIG. 8). Further, although the electric motor 35 is arranged on the back side of the disc member 20, it is also possible to arrange the electric motor 35 in a place other than that and to transmit the rotational force of the electric motor 35 to the disc member 20 and/or the fan 22. It doesn't matter if it's a structure. Moreover, the features of the above-described embodiments and modified examples are mutually applicable, and furthermore, it is possible for those skilled in the art to make changes (modifications) that come to mind within the obvious range.

According to the present invention, it is possible to provide a rotating magnetic therapy device that makes it easy to grasp the location where the magnetism hits.
