[0002] Ocular magnetic stimulation is a treatment method that uses magnetic fields to stimulate the eyes, aiming to improve eye health and vision problems. This method uses the energy of the magnetic field to promote blood circulation in the eyes and relieve eye fatigue. It has a positive intervention effect on some eye diseases.

[0003] The magnetic field generating devices in the existing eye magnetic stimulators mostly use magnetic steel. For example, the element that provides the magnetic field in an existing eye magnetic stimulator is a physical therapy magnetic block.

The switch circuit 14 is electrically connected to the drive module 15 and the power supply 13 respectively. The drive module 15 is also electrically connected to the output selection module 16. The switch circuit 14 is electrically connected to the magnetic field generating device 9 via a cable 8. The power supply 13 is used to output direct current. The output selection module 16 is used to output different pulse signals to change the frequency of the waveform output by the drive module 15. The drive module 15 is used to output waveforms of different frequencies to the switch circuit 14 to control the conduction time of the switch circuit 14, thereby changing the current waveform of the output current of the control device. Specifically, different output waveforms can be selected through the output selection module 16, so that the drive module 15 controls the on-off time of the switch circuit by outputting waveforms of different frequencies, thereby flexibly adjusting the mode and intensity of magnetic stimulation.

[0032] In this embodiment, the power supply 13 includes a power supply circuit 17, a power frequency transformer 18 and a rectifier bridge circuit 19 which are electrically connected in sequence, and the AC power of the power supply circuit 17 is converted into the DC power required by the power supply 13. The power frequency transformer 18 transforms the input AC mains into a certain voltage lower than the AC mains voltage through different turns ratios of the primary side and the secondary side. Specifically, the power supply circuit 17 is connected to the AC mains, the rectifier bridge circuit 19 is connected to the switch circuit 17, and the switch circuit 17 is connected to the conductive coil of the magnetic field generating device 9. With this structure, the AC mains supplies power to the power frequency transformer 18, and the AC mains is transformed into an AC power lower than the AC mains by the power frequency transformer 18, and the AC power is converted into a DC power by the rectifier bridge circuit 19.

In this embodiment, the rectifier bridge circuit 19 includes a rectifier bridge and related circuits with capacitors as main components or composed of capacitors and inductors, and the switch circuit 14 includes switch devices such as MOS tubes or IGBTs and other related devices with high-frequency switching functions.

[0033] In this embodiment, the main functional element of the driving module 15 is a transistor. The driving module 15 may include a single transistor or a push-pull circuit composed of multiple transistors. The conduction of the transistor is controlled by a pulse signal, thereby controlling the operation of the switching circuit 14.

[0034] In this embodiment, please refer to Figure 7 , the driving module 11 outputs PWM, keeps the cycle of a single PWM constant, the initial duty cycle is 0%, and as time goes by, the duty cycle gradually increases and eventually reaches 50%, and then as time goes by, the duty cycle gradually decreases and eventually becomes 0%, realizing a set of sinusoidal wave outputs. After such control, the waveform acting on the load (magnetic stimulation actuator 5) becomes: the amplitude of the initial waveform is 0, and as time goes by, the amplitude gradually increases until it reaches the maximum, and then as time goes by, the amplitude gradually decreases until it reaches 0. Add an inductor L and select a suitable inductance value to achieve the purpose of boosting, thereby increasing the magnetic field strength.

[0035] In this embodiment, the switch circuit in the present invention includes a MOS tube or an IGBT, a device that can realize high-frequency conduction and shutdown. Then the magnetic stimulation actuator is used as a load, one end is connected to the power supply, and the other end is connected to the D pole of the MOS tube or the C pole of the IGBT. When the MOS tube or the IGBT is turned on, the voltage acting on the magnetic stimulation actuator is the power supply voltage. In order to increase the voltage on the magnetic stimulation actuator so as to increase the magnetic field strength generated by the magnetic stimulation actuator without changing the power supply voltage, an inductor is added to the load end. One end of this inductor is connected to the power supply, and the other end is connected to the magnetic stimulation actuator, that is, this inductor is connected in series with the magnetic stimulation actuator. As is well known, the inductor, as an energy storage element, has the function of boosting, that is, when the MOS tube or the IGBT is turned on, the voltage acting on the magnetic stimulation actuator can be twice the power supply voltage, generating a greater magnetic field strength to achieve an enhanced magnetic stimulation effect on the eye.

A second magnetic field is also generated between the ends of the same end of the two adjacent magnetic field generating devices 9, and the magnetic field direction of the second magnetic field extends along the circumference of the human head. The magnetic flux lines of the first magnetic field and the second magnetic field pass through the human eye and induce an induced current in the eye, and the current waveform of the output current of the control device is changed to change the magnetic field mode of the magnetic field in which the eye is located. The magnetic field provided by the mode-adjustable eye magnetic stimulator provided by the present invention has magnetic flux lines that pass through the eye approximately vertically (such as Figure 2b As shown in the figure, this magnetic induction curve passes through the eyes more smoothly, which helps with daily eye care.

[0039] An embodiment of the present invention provides an eye magnetic stimulator with adjustable mode, which provides direct current power through the power supply of the control device, and further generates a square wave or sine wave current by adjusting the mode. The current then generates a magnetic field through a conductive coil.
