Air activator

The utility model provides an air activator, air activator include casing and two at least discharge ends, wherein are provided with two at least holding holes that correspond with the discharge end on the casing, and the discharge end sets up in the holding that corresponds downtheholely, and the casing is provided with hollow out construction between the discharge end, and the discharge end includes that discharge electrode, cover locate the round annular metal piece in discharge electrode ring week and locate the potsherd of round annular metal piece bottom, discharge electrode and the sheetmetal formation return circuit of discharging. In this way, the utility model discloses can effectively cut off the discharge end, and then the short circuit phenomenon between the discharge end of avoiding leading to because the carbon that carbon dioxide decomposes attaches to the surface of casing. In addition, locate discharge electrode's ring week through making plausible the annular metal piece to the centre of a circle position that makes discharge electrode be located round annular metal piece sets up, has guaranteed the distance stability between discharge electrode and the sheetmetal, improves discharge efficiency.
