Embodiment Construction

[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, and the voltage doubler rectifier [2] converts it into positive and negative two High voltage and a ground potential output; the positive electrode 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 released under the action of the high voltage electric field It is collected on the dust-collecting electrode, and at the same time, an ion wind is formed to push the air forward. The auxiliary electrode [4] is connected with 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 fibers (such as carbon fibers);...

Abstract

The electrostatic air purifier with controllable ozone concentration can control the ozone concentration automatically in required range by means of detecting the output ozone concentration, regulating the width and interval of pulse the MCU generates, and further controlling the high voltage electrostatic amplitude the high voltage pulse converter and the voltage doubling rectifier output. In this way, the low concentration ozone is utilized in sterilizing, deodorizing and decomposing pollutant while maintaining its concentration in safety sanitary level. In addition, the air purifier can generate negative air ion beneficial to health.

Description

technical field [0001] The invention relates to an electrostatic air treatment device, in particular to a device capable of generating air negative ions and ozone. Background technique: [0002] Expired US Patent No. 4,789,801 relates to an electrokinetic electrostatic filter. It has two sets of main electrodes, which are discharge electrodes and dust collection electrodes; high-voltage static electricity is added between the two sets of electrodes to push the ionizable flow medium (such as air) between the two sets of electrodes to move to form a directional airflow. The shape and position of the two sets of electrodes are designed so that one set of electrodes can generate corona discharge, and the other set of electrodes can collect the dirt in the air. This structure can be used to make air purifiers. [0003] There are also many electrostatic air cleaners similar to the above patents. They are all composed of a high voltage generator, a discharge electrode and a dust...
