Description

[Detailed Description of the Invention] Conventional battery-powered rotating magnet therapy devices use a normal micromotor to rotate a magnet to obtain therapeutic magnetic field waves, but the batteries are consumed rapidly and maintenance costs are high. There are some drawbacks.

In view of this, in the present invention, the magnet is rotated in a gyroscopic manner, and the inertia effect during rotation is utilized to reduce the battery power used to drive the magnet rotation to approximately one-fiftieth of that of conventional products, which consumes very little battery power. It's better.

An embodiment of the present invention will be described with reference to the drawings. A magnet rotor (2), which has both conical shaft ends, is rotatably supported on a body frame (2) by pot-shaped bearings (2) and (2), which are a type of point contact type bearings. , a generator coil (2) and a counter-drive coil (2) connected to a transistor switch circuit (2nd -) are fixed to a body frame (2) facing the magnet surface of a magnet rotor (2).

Now, when the magnet rotor ■ is turned by hand, a voltage is generated in the generator coil ■ facing the magnet rotor ■ due to the magnetic poles of the magnet rotor ■, and the current acts as an input to the transistor ■, which transfers battery current to the drive coil ■. Drive coil generated by the current
The magnetic poles of the magnet rotor ■ repel the same magnetic poles of the opposing magnet rotor ■, causing the magnet rotor ■ to rotate, and when it rotates half a rotation, the opposing magnetic poles of the generator coil ■ are the opposite poles of the first case, and the generated voltage Due to the reverse voltage, battery current is not passed through the drive coil (■) due to the switching action of the transistor (■).In the next half rotation, the battery current is passed as in the beginning, and the rotation continues sequentially, and the magnetic lines of force necessary for treatment are transmitted from the magnet rotor (■). waves are emitted.

The present invention increases the moment of inertia of the magnet rotor due to the inevitable weight caused by the metal material of the magnet rotor and the mechanical friction of the bearing that supports the magnet rotor, and drives the magnet rotor using an induction drive method. It rotates mechanically like a gyro in a no-load rotation state, and utilizes the inertia effect during rotation to prevent rotational attenuation, reduce loss of rotational energy, and reduce induction drive battery life. According to actual measurements, the current consumption was less than IMA at a supply voltage of 1.5V.Incidentally, the conventional product has a power consumption of 50MA or more at 1.5V, so the present invention consumes about 1/50th the battery power of the conventional product. Moreover, since the structure of the present invention makes almost no noise during use, there is also the effect that the present invention can be used without bothering others, especially when used at night.

The magnetic rotor, generator coil, drive coil, and transistor switch circuit, which are the structural components of the induction drive method of the present invention, are as follows:
As in the above embodiment, as long as the overall correspondence can be satisfied, the arrangement can be changed in various ways simply by changing the design.
By changing the direction of the magnetic poles of the magnet rotor, it is also possible to arrange the generator coil and drive coil so that they are perpendicular to or parallel to the axis of the magnet rotor. They can also be stacked together and placed in one place. Further, in the above embodiment, in order to simplify the explanation, the case where the magnetic rotor has two magnetic poles has been explained, but it can also be made with two or more magnetic poles. It is also possible to use a bearing other than the mortise-type equal point contact type for the magnetic rotor bearing, but the inertia effect will be reduced. When carrying out the present invention, it is convenient to attach a starter as shown in Fig. 3.
