Description: This negative oxygen ion generator circuit consists of a steady voltage power supply circuit, an under-voltage detection indication circuit, a high-frequency oscillator, and a high-voltage generator circuit, as illustrated in figure 9-113. The steady voltage power supply circuit is composed of diode VD1, voltage regulator V1, and steady voltage diodes VS1 and VS2, along with an ionization selection switch S, a power supply indication LED VL2, and associated resistor-capacitor components. The under-voltage detection indication circuit includes transistors V3 and V4, steady voltage diode VS3, an under-voltage indication LED VL1, and additional peripheral resistor-capacitor components.
The negative oxygen ion generator circuit is designed to produce negative ions, which can enhance air quality by neutralizing pollutants and allergens. The steady voltage power supply circuit ensures that the system operates reliably by maintaining a consistent voltage level. Diode VD1 rectifies the input voltage, while voltage regulator V1 stabilizes the output voltage, preventing fluctuations that could affect the performance of the circuit. The steady voltage diodes VS1 and VS2 are used to provide additional voltage regulation and protection against voltage spikes.
The ionization selection switch S allows the user to control the ionization process, enabling or disabling the generation of negative ions as needed. The power supply indication LED VL2 serves as a visual indicator, confirming that the circuit is powered and functioning correctly. The peripheral resistor-capacitor components work in conjunction with the aforementioned elements to filter noise and stabilize the circuit operation.
The under-voltage detection circuit plays a critical role in safeguarding the device from operating under insufficient voltage conditions. Transistors V3 and V4 are configured to monitor the voltage levels, and when the voltage drops below a predetermined threshold, steady voltage diode VS3 activates the under-voltage indication LED VL1. This LED serves as a warning signal, alerting the user to the low voltage condition that may compromise the operation of the ion generator.
The high-frequency oscillator and high-voltage generator circuit are essential for generating the necessary high voltage required for ionization. The oscillator produces a high-frequency signal that is then amplified by the high-voltage generator, enabling the circuit to create the electric field necessary for the ionization process. This combination of components ensures that the negative oxygen ions are produced efficiently and effectively, contributing to improved air quality in the surrounding environment.
