Description

  The present invention relates to a magnetic health device using a permanent magnet that is easy to carry, and more particularly to a magnetic health device that is easy to manufacture and can improve the feeling of use.

As this type of magnetic health device, there is well known a device in which a small disk-shaped permanent magnet having a diameter of about several millimeters is attached to the body by an adhesive sheet and health is promoted by the action of magnetic force. It is said that the magnetic lines of force generated from the magnet cut blood, muscles, and the like to generate an electric current in the portion, which promotes blood circulation and relaxes muscle stiffness, and is effective in promoting health.
The magnetic health device is attached to a predetermined part of the body to give an action of magnetic force, but since there is no movement in the magnetic force, it cannot give sufficient stimulation inside the healing part, There is no effect of obtaining a massage effect, and there is a waste of being disposable after use.

A magnetic health device has been disclosed in which a variable magnetic field (magnetic field) is applied by displacing a magnet relative to the body so that the lines of magnetic force of muscles and blood greatly cut the relative displacement speed (patent) Reference 1).
In the above disclosure, in order to obtain a synergistic effect between the massage effect and the magnetic effect by applying a magnetic field with a fast fluctuation speed while applying massage to a required part of the body, a permanent magnet is attached to the vibration member of the vibrator for massage. Realizes a magnetic health device with removable magnetic means.
However, in the above disclosure, there is a restriction on the place of use because a vibrator power supply is required, and even if a battery can be used for portable use, a coil to be vibrated is required, resulting in an increase in manufacturing cost. Noise is generated, and on the other hand, consumables such as a battery are required for the user, which is not easy to use. Note that a magnet having a predetermined magnetic field is magnetized in the thickness direction on the base material, and it is indispensable to have a vibrating means (vibrator) in order to obtain a variable magnetic field with a high fluctuation speed.

Further, the casing can be grasped as a whole and has a pressing portion that is pressed against a healing portion of the body, and an electromagnet or a permanent magnet provided in the casing is configured to vibrate the pressing portion, and the pressing A magnetic therapy massager that generates an alternating magnetic field (a magnetic field in which the direction of the magnetic field lines alternately change) or a variable magnetic field (which changes the magnetic force or moves the magnetic field) is disclosed from the portion or the vicinity thereof to the outside ( Patent Document 2).
The above disclosure gives a mechanical massage by pressing the pressing part against the healing site of the body to vibrate, and an alternating magnetic field or a varying magnetic field passes through the inside of the healing site to naturally heal blood, nerves, or skeleton It gives an effective stimulus with power.
As a first embodiment of the above-mentioned Patent Document 2, a flat permanent magnet (centered on the rotation shaft) magnetized with N and S poles attached to the tip of the rotation shaft projecting from a motor installed in the casing. (A single permanent magnet with N and S poles facing each other) rotates to generate an attractive force with the iron core excited by a coil provided inside the casing pressing portion. It is disclosed that a magnetic field that vibrates by passing through a pressing portion from an iron core and gives a magnetic stimulus to a healing site to increase the healing effect while vibrating and giving a massage effect.
However, in the disclosure of Patent Document 2, similarly to Patent Document 1, there is a need for a power source that generates vibration, and there are restrictions on the place of use, and a coil that vibrates is required, which increases manufacturing costs and uses a battery. , The user needs consumables such as batteries, and there is a problem with the durability of the casing due to vibration, and measures such as embedding a spring made of steel wire are necessary to make it durable and structurally complicated. The manufacturing cost is also increased, and the coil built in the casing is energized, so the coil part generates heat and the pressing part is heated, causing the user to feel uncomfortable with the temperature rise due to prolonged use. Is not good. Although mention is made of providing a fan in order to prevent the temperature from rising, there is a problem that the structure becomes complicated and the manufacturing cost increases, and the user feels uncomfortable due to noise.

Further, in the conventional technique, a cylindrical head and a head that are coaxially and rotatably fitted on a support rod, a grip connected to the support rod and the support rod, and are rolled on the skin surface of the cosmetic treatment target. There is disclosed a beauty treatment apparatus including a light irradiation means for generating electric power by a coil and a permanent magnet by rotation and stimulating the skin based on the generated electric power and / or an electrode for passing an electric current to the skin (Patent Document 3). ).
The disclosure of Patent Document 3 is a beauty processing apparatus that includes power generation means and can easily and economically perform beauty processing anytime and anywhere. A coil and a permanent magnet are provided as power generation means, and a current flows through the coil by the rotation of the head, and the skin is stimulated by the light irradiation means and / or an electrode that passes a current through the skin.
The means of Patent Document 3 is arranged at the tip of the cylindrical head suitable for cosmetic treatment, and the positions of the coil and the permanent magnet are arranged at the other end of the grip side head. The main purpose is to stimulate the skin with the power generated by the power generation means, and no mention is made of the healing effect of the magnetic field generated from the permanent magnet. Does not appear. When the positions of the power generation means of the coil and the permanent magnet are arranged on the grip side, it is not possible to expect the healing effect of the magnetic field generated from the permanent magnet. Further, the strength of the magnetic field stimulates the skin with a certain strength of the magnetic field of the permanent magnet.
Furthermore, in the disclosure of Patent Document 3, the head formed in an octagonal cross section that rolls and rotates on the skin surface of the beauty treatment target rolls smoothly on the skin surface and presses the skin with a force pressing against the face or body. The massage effect is demonstrated by rubbing, but since there is no rolling resistance and there is no feeling of use (click feeling), the head rolls smoothly on the skin surface, and it is not possible to obtain a side-up or lift-up effect or tapping effect, and the user It was unsatisfactory for me.
In addition, the structure is complicated and the manufacturing cost is expensive, such as a light irradiation means and / or an electrode (beauty treatment means) for passing an electric current to the skin, a coil for generating electric power and a plurality of permanent magnets, and a control device. There is a problem such as becoming.

Furthermore, as a conventional technique, there is disclosed a magnet beauty tool in which a plurality of granular magnets are embedded in an equatorial part of a substantially spherical body attached to the tip of a handle so as to be rotatable about a shaft (Patent Document 4). Many massage devices have been proposed.
In the instrument of the above-mentioned patent document 4, in order to increase the change and movement of the magnetic lines of force with respect to the living body, a plurality of magnets are embedded in the roller and used by being reciprocated by pressing against the face and body.
However, the strength of the magnetic field of the magnet embedded in the roller is constant, and as the roller rotates, the change in the magnetic field lines with respect to the living body only occurs to stimulate the skin. The attractive force between the magnets is canceled out because the magnet is fixed to the roller, and the roller rolls smoothly on the skin surface and exerts a massage effect by rubbing the skin with the force of pressing against the face and body, but rolling Since there is no resistance, there is no click feeling, it is not possible to obtain a flip-up effect or a lift-up effect or a tapping effect that repels, and it is the same as in Patent Document 3 that a satisfactory use feeling cannot be obtained for the user. .

The cylindrical head 6 may have the same polarity as the cylindrical head 6 is opposed during rotation, and there may be a click feeling caused by repulsion.

Next, the above operation will be described.
First, the support rod 1 and the grip portion 2 are grasped by hand, and the cylindrical head 6 is pressed against the healing portion of the body so as to roll and used. As the permanent magnet 41 rotates, a larger alternating magnetic field (magnetic field) is generated between the permanent magnet 42 and the outside of the cylindrical head 6, and passes through the inside of the healing site to naturally occur in blood, nerves, or the skeleton. Provides effective stimulation with healing power. A larger alternating magnetic field (magnetic field) can be obtained than an alternating magnetic field (magnetic field) obtained by simply providing a permanent magnet on the surface or inside of a conventional roller, and more effective stimulation can be given to the living body.
When the cylindrical head 6 is pressed and rolled, the skin is caught in the recess between the round bar 10 and the round bar 10 arranged around the cylindrical head 6, picking up the skin, and the permanent magnet 41 of the massage roller , 42 has a lift-up action that repels the skin due to the click feeling caused by the increase or decrease of the repulsive force.
That is, in the process of rotating and rotating the cylindrical head, when the 90-degree rotation of the positional relationship shown in FIG. 7 is rotated from the positional relationship of the permanent magnets 41 and 42 shown in FIG. At first, when a feeling of resistance to rotation and rotation occurs, and when the permanent magnets 41 and 42 are aligned (180 degrees), the resistance becomes maximum, and a force exceeding the resistance is applied to form a cylinder. When the head is rotated, the same poles do not face each other, so the repulsive force sharply decreases to cause a click feeling, and at the same time, the user can feel the click feeling caused by the repulsive force on the skin and hand, Satisfaction with the feeling of use increases.
Massage having various effects of different repulsive forces and feelings on the skin and hands depending on the combination of the number of permanent magnets 41 and 42 attached to the outer peripheral surface of the shaft 50 and the outer peripheral surface or inner peripheral surface of the annular cylindrical portion 18 I was able to provide a roller.
Moreover, since the acupressure parts 4 and 11 are provided at both ends, a massage roller having an effect as an acupressure tool can be provided by pressing the acupressure part 4 or 11 against the healing site of the body according to the user's preference.
