Description

Positive and negative ion generator fault diagnosis control circuit

Technical Field

The utility model relates to the technical field of positive and negative ion generators, in particular to a fault diagnosis control circuit of a positive and negative ion generator.

Background

At present, the traditional positive and negative ion generators work continuously, simultaneously output positive and negative high voltages, are added on different point discharge electrode devices to ionize air to respectively generate positive and negative ions, and utilize the energy generated when the positive and negative ions are combined in the air to kill harmful bacteria floating in the air. The input power source is generally direct current 5V to 24V weak current or 100V to 240V, 50/60Hz alternating current. The positive and negative ion generator input by the DC power supply adopts a self-excited or separately excited oscillating circuit, then generates high-frequency pulse high voltage by boosting through a step-up transformer, and respectively generates positive and negative high voltage after voltage-doubling rectification. Then the air is ionized by the point discharge electrode device to generate positive and negative ions. The positive and negative ion generator for AC power supply is to rectify AC power, then to form LC resonant circuit via the primary of step-up transformer and capacitor C, to generate high frequency pulse high voltage via step-up transformer, and to generate positive and negative high voltages via voltage doubling rectification. In the process of generating positive and negative ions, the positive and negative ion generating circuits can break down, especially when the negative ion generating circuit breaks down, the positive and negative ion generator can not generate negative ions, and if the positive and negative ion generator does not stop working, the quantity of positive ions in the environment can be increased dramatically, thus causing harm to human bodies. At present, most of the indirect means of environment detection is used for judging the content of positive and negative ions in the environment to acquire whether the positive and negative ion generator has a negative ion generating circuit fault or not, the direct means is not used for detecting and controlling the fault, and the indirect means cannot detect and control the fault quickly, accurately and in real time.
