[0002] Insomnia refers to a subjective experience in which patients are not satisfied with their sleep time and / or quality, which affects their daytime social functions.

Insomnia can have a negative impact on human health, such as decreased immune system function, endocrine disorders, and abnormalities in the nervous system.

[0003] The methods commonly used to treat insomnia in the prior art are sound therapy, transcranial magnetic stimulation therapy or spectrum heating therapy. Sound therapy changes the brain wave frequency in the brain or stimulates the brain's relaxation response by playing sounds of specific frequencies and tones, thereby soothing the body and mind. Spectrum heating therapy generates far-infrared spectrum light waves on the human body through a spectrum heating plate, thereby promoting sleep.

[0031] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] Circuit Example for Treating Insomnia:

[0033] like Figure 1 As shown, the circuit for treating insomnia of the present invention comprises: a host computer and a spectrum heating circuit, a sound therapy circuit and a transcranial magnetic circuit connected to the host computer.

[0034] The first optocoupler control circuit includes: a zero-crossing detection circuit for detecting whether the voltage of the AC power supply passes through zero, a first control chip and a first control switch Q1, one end of the primary side of the first optocoupler is connected to a 5V power supply voltage, and the other end is grounded GND through the first control switch, the controlled end of the first control switch is connected to the first control chip, the first control chip is connected to the zero-crossing detection circuit to receive a voltage zero-crossing signal of the AC power supply, and the first control chip is also connected to the host computer to generate a first PWM waveform according to the instructions of the host computer and the voltage zero-crossing signal to control the first control switch to periodically turn on and off.

[0035] The spectrum heating circuit can produce a warming effect on the human body through far-infrared spectrum light waves. This effect can promote blood circulation, relieve muscle tension, and help the brain and body relax, thereby helping to improve sleep quality; the sound therapy circuit can relieve one's own tension and muscle relaxation, and the transcranial magnetic circuit can non-invasively penetrate the head to reach the deep soft tissue in the brain to achieve the purpose of treatment, which can relieve insomnia and cerebral ischemia symptoms; the circuit for treating insomnia of the present invention integrates a spectrum heating circuit, a sound therapy circuit and a transcranial magnetic circuit, so that insomnia patients can be treated more comprehensively and effectively, making it easier for insomnia patients to fall asleep; in addition, since a negative oxygen ion generator is provided in the spectrum heating circuit, while treating insomnia through spectrum heating, the air content can be increased, thereby reducing the discomfort caused to the patient during infrared light treatment, thereby further improving the treatment effect of insomnia.

[0036] In one embodiment, a first resistor R4 is connected in series between the controlled end of the first control switch and the ground end, and the controlled end of the first control switch is connected to the first control chip through a first current limiting resistor R2.

[0037] like Figure 3 As shown, in one embodiment, the zero-crossing detection circuit includes: a third optocoupler U5 and a first voltage-dividing branch, the two ends of the primary side of the third optocoupler are respectively connected to the neutral line and the live line of the AC power supply, one end of the secondary side of the third optocoupler is grounded GND, and the other end is connected to the voltage-dividing point ZERO of the first voltage-dividing branch, one end of the first voltage-dividing branch is grounded, and the other end is connected to the 5V power supply voltage, and the voltage-dividing point ZERO of the first voltage-dividing branch is connected to the first control chip. In this embodiment, the first voltage-dividing branch includes resistors R6 and R7 connected in series.

[0038] The third optocoupler uses an optocoupler chip model TLP620.

[0039] Since the two ends of the primary side of the third optocoupler are respectively connected to the neutral line and the live line of the AC power supply, when the AC power supply voltage is 0, the optocoupler is cut off, and the potential of the voltage dividing point of the first voltage dividing branch is 0; when the AC power supply voltage is not 0, the optocoupler is turned on, and the potential of the voltage dividing point of the first voltage dividing branch is not 0, thereby realizing the voltage zero crossing detection of the AC power supply.

[0040] In one embodiment, the transcranial magnetic circuit includes: a second control chip, the second control chip is connected to the first vibration circuit and the pulse magnetic field generating circuit to control the working state of the first vibration circuit and the pulse magnetic field generating circuit; Figure 4 As shown, the first vibration circuit includes a vibration motor, one end of the vibration motor power supply end is connected to the 5V power supply voltage through a pull-up resistor R9, and the other end is grounded through a fourth control switch Q2, and the controlled end of the fourth control switch is connected to the second control chip. The vibration motor power supply end is also connected in parallel with a freewheeling diode D3 and a first filter capacitor C20.

[0041] In the case of power failure or current mutation, a high self-inductance reverse potential will be generated in the power supply circuit of the vibration motor. If this reverse potential is too high, it may harm other components in the circuit. After the freewheeling diode is connected in parallel, when the motor is powered off or the current suddenly changes, the freewheeling diode can be quickly turned on to provide a low-impedance discharge path for the reverse potential, thereby effectively protecting the components in the circuit from breakdown or damage. By connecting the first filter capacitor in parallel to the power supply end of the vibration motor, interference signals can be filtered out, making the vibration motor work more stable.

[0042] The transcranial magnetic circuit of the present invention is not only provided with a stimulation coil, but also provided with a vibration circuit so as to perform vibration massage on the patient's head, which helps the patient to relax physically and mentally, thereby improving sleep more effectively.

[0043] In one embodiment, the fourth control switch Q2 is a triode, a second resistor R15 is connected in series between the base and the emitter of the fourth control switch Q2, and the base of the fourth control switch Q2 is connected to the second control chip via a fifth current limiting resistor R12.
