Moreover, the position of the skin S to which the rotating magnetic therapy device 1 is attached is not particularly limited as long as it is a position where the magnetic therapy effect is exerted, and it can be any position such as a shoulder, an arm, a neck, a waist, or a leg of a human body. It may be a position.

  As shown in FIGS. 1 and 2, the rotating magnetic therapy device 1 of the present embodiment supports a housing 2, a treatment magnet portion 3 housed in the housing 2, and a treatment magnet portion 3. The support base 4 and the rotation drive device 5 that rotationally drives the support base 4 are provided. As will be described in detail below, the rotary magnetic therapy device 1 rotates the support base 4 by the rotation drive device 5 to rotate the therapeutic magnet portion 3 supported by the support base 4 and thus to the skin S of the human body. A fluctuating magnetic field is generated.

  In the present embodiment, the rotary magnetic therapy device 1 supplies electric power to the circuit board 9 for controlling the operation of the rotary magnetic therapy device 1, the circuit board 9 and the rotary drive device 5, as shown in FIG. 2. It further includes a battery 10, a switch 11 for turning on / off the power supply of the rotating magnetic therapy device 1, and a USB terminal 12 for supplying electric power to the battery 10 from the outside in order to charge the battery 10. The rotating magnetic therapy device 1 further includes the circuit board 9, the battery 10, the switch 11, and the USB terminal 12, and thus functions as a magnetic therapy device that can be controlled as a single unit. However, the rotating magnetic therapy device 1 is not limited to this embodiment, and may be operated by external control without including the circuit board 9, the battery 10, the switch 11, and the USB terminal 12.

  The housing 2 houses the components that make up the rotating magnetic therapy device 1. As shown in FIG. 1B, the housing 2 is arranged at a position where it directly or indirectly contacts the skin S when the rotating magnetic therapy device 1 is attached to the skin S of the human body. The housing 2 has an internal space that accommodates the components that make up the rotating magnetic therapy device 1, and the upper surface, the side surface, and the rotating magnetic therapy device 1 that surround the internal space are attached to the skin S. The bottom surface 21 that directly or indirectly contacts the skin S when the user touches the skin. The rotating magnetic therapy device 1 is used by being attached to the skin S of the human body so that the bottom surface 21 of the housing 2 directly or indirectly contacts the skin S of the human body.

  In this embodiment, the housing 2 is formed in a substantially columnar shape or a substantially disk shape as shown in FIGS. 1 (a) and 1 (b). However, the housing 2 is not particularly limited as long as it has an internal space for accommodating the components of the rotating magnetic therapy device 1 and a bottom surface 21 that directly or indirectly contacts the skin S of the human body. However, it may be formed in a substantially prismatic shape or the like. Further, the material forming the housing 2 is not particularly limited, but has a strength capable of protecting the components to be housed against a force received from the outside, and has a magnetic force line of the therapeutic magnet unit 3. Is preferably permeable, and synthetic resin materials such as acrylonitrile butadiene styrene (ABS), polycarbonate acrylonitrile butadiene styrene (PC-ABS), polyethylene (PE) and polyethylene terephthalate (PET) can be preferably used.

  The therapeutic magnet unit 3 has two magnetic poles (N pole and S pole) and generates a magnetic field that can affect the skin S of the human body. As shown in FIG. 2, the therapeutic magnet unit 3 is supported by the support base 4, and is rotated by the rotation drive device 5 rotating to generate a fluctuating magnetic field. In this specification, the term “fluctuation magnetic field” means a magnetic field in which the direction and strength of the magnetic field fluctuate. In the rotating magnetic therapy device 1, the therapeutic magnet unit 3 is rotated to generate a fluctuating magnetic field, thereby eliminating so-called "snarling" in the body of the skin S surface and the vicinity of the skin S surface, and exerting a high magnetic therapy effect. can do.

  The therapeutic magnet portion 3 is shown in FIGS. 2 and 3, and as will be described in detail below, the support base 4 rotates about a rotation axis 6 extending substantially perpendicular to the bottom surface 21 of the housing 2. As a result, the housing 2 rotates in a plane substantially parallel to the bottom surface 21. When the rotating magnetic therapy device 1 is attached to the skin S of the human body, the therapeutic magnet unit 3 rotates in a plane substantially parallel to the bottom surface 21 of the housing 2 so as to cover a wide range of the skin S. A fluctuating magnetic field can be generated across.

  In the present embodiment, the therapeutic magnet unit 3 includes a plurality of (two in the illustrated example) therapeutic magnets 3a and 3b, as shown in FIGS. 2 and 3. The plurality of treatment magnets 3a, 3b have a magnetic pole direction that extends substantially perpendicular to the bottom surface 21 of the housing 2, and are adjacent to each other in the rotation direction of the support 4 among the plurality of treatment magnets 3a, 3b. The matching therapeutic magnets 3a and 3b have magnetic pole directions that are substantially opposite to each other. The plurality of treatment magnets 3 a, 3 b are arranged apart from each other along the rotation direction of the support base 4, and the plurality of treatment magnets 3 a, 3 b rotate by the rotation of the support base 4 to alternate. It is configured to generate a magnetic field. In the illustrated example, the therapeutic magnet 3a is magnetized so that the bottom surface 21 side is the S pole and the opposite side to the bottom surface 21 is the N pole (the magnetic pole direction is the bottom surface 21 side), and the therapeutic magnet 3a is 3b is magnetized so that the bottom surface 21 side is the N pole and the opposite side to the bottom surface 21 is the S pole (the magnetic pole direction is opposite to the bottom surface 21). Therefore, at a specific position on the rotation orbits of the therapeutic magnets 3a and 3b, each time the support base 4 rotates once, an upward and downward magnetic field in a direction substantially perpendicular to the bottom surface 21 of the housing 2 occurs once. It occurs by turns. In this way, the therapeutic magnet unit 3 includes a plurality of magnets whose magnetic pole directions are opposite to each other, so that the change in the magnetic field strength received by the skin S when the therapeutic magnet unit 3 is rotated is in the same direction. Compared with the case of using a magnet having a facing magnetic pole direction, the size is approximately doubled, and a larger fluctuating magnetic field can be generated. Furthermore, since the magnetic pole directions of the therapeutic magnets 3a and 3b used extend substantially perpendicularly to the bottom surface 21 (and the skin S surface) of the housing 2, the magnetic pole direction is parallel to the bottom surface 21 (and the skin S surface). The magnetic field strength in the direction substantially perpendicular to the surface of the skin S is increased as compared with the case of using the magnet extending to, and the magnetism can be applied from the surface of the skin S to a deeper body.

It may be provided with a magnet, may be provided with a plurality of therapeutic magnets having magnetic pole directions that are oriented in the same direction, and may be provided with a magnetic pole direction that is not substantially perpendicular to the bottom surface 21 of the housing 2. It may have a magnet.

  As shown in FIGS. 2 and 3, the plurality of treatment magnets 3a and 3b of the treatment magnet unit 3 are arranged at positions separated from the center of rotation of the support base 4 by substantially the same distance. Therefore, each of the plurality of treatment magnets 3a and 3b rotates on a common orbit and generates an alternating magnetic field on the common orbit. However, the plurality of treatment magnets 3 a and 3 b may be arranged at positions separated from the substantial center of the support base 4 by different distances. In addition, the distances of the plurality of treatment magnets 3a and 3b from the substantially center of the support base 4 can be appropriately set according to the range of the skin S on which the magnetic treatment effect is desired.
