Rotating magnetic field therapy device

Abstract

The invention provides a rotating magnetic field therapy device, which comprises a drive motor and a cylindrical permanent magnet component, wherein the cylindrical permanent magnet component is of a three-layer structure and comprises a middle magnetic material layer located in the middle of the permanent magnet component, an upper permanent magnet material layer located at the upper part of the permanent magnet component, and a lower permanent magnet material layer located at the lower part of the permanent magnet component; both the upper permanent magnet material layer and the lower permanent magnet material layer are attached to the middle permanent magnet material layer; the polarities of the upper permanent magnet material layer and the lower permanent magnet material layer are the same on the opposite surfaces; a first connection shaft connected with the drive motor is arranged at one end of the middle magnetic material layer near the drive motor, and the first connection shaft and the middle magnetic material layer are of an integrally moulded structure. According to the rotating magnetic field therapy device provided by the invention, the operation can be more stable when the drive motor drives the permanent magnet component to rotate through the first connection shaft, and the service life of the device can be effectively prolonged.

Description

technical field [0001] The invention relates to magnetic field therapy technology, in particular to a rotating magnetic field therapy device. Background technique [0002] Studies have found that the magnetic field has a significant impact on the human body and other organisms, and various diseases of the organism can be treated by using the magnetic field. The magnetic field treatment device is a kind of permanent magnet as a magnetic source, which generates a magnetic field and exposes it to the part to be treated of the living body, so as to achieve the purpose of treatment. [0003] A rotating magnetic field treatment device provided in the prior art can be as figure 1 As shown, the permanent magnet component of the rotating magnetic field treatment device is a cylindrical structure, which is composed of two cylindrical permanent magnets 1 arranged side by side, and the S poles of the two cylindrical permanent magnets are oppositely arranged, and the magnetic The sense...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned rotating magnetic field treatment device needs to set a connecting shaft between the permanent magnet part and the drive motor to realize the drive motor to drive the permanent magnet part to rotate, and the permanent magnet part is made of permanent magnet materials such as rare earth, and the hardness of this type of permanent magnet material is And the toughness is relatively poor, which makes it easy to wear at the connection between the connecting shaft and the permanent magnet parts. At the same time, this wear will also cause the connection to be weak, which will affect the stability of the device during use and shorten the service life of the device.
