[0020] The pulse high-voltage converter [1] in Figure 1 converts the high-frequency pulse signal generated by the MCU[8] into a high-voltage pulse and boosts it to a range of 6KV to 8KV. The voltage doubler rectifier[2] converts it into positive and negative two High voltage and a ground potential output; the positive pole is connected to the discharge electrode [3], and the ground potential is connected to the dust collecting electrode [4]; the dust and other pollutants contained in the air between the two electrodes will be affected by the high-voltage electric field. It is collected on the dust collecting electrode, and at the same time an ion wind is formed, which pushes the air forward. The auxiliary electrode [4] is connected to the negative electrode of the voltage doubler rectifier through a conductor or wire. The auxiliary electrode can be made of a metal plate with a pointed shape, or it can be made of conductive fiber (such as carbon fiber); it has a number to the groun...
