A mask having a fine charged part by corona discharge

摘要

Problem to be solved: to provide a mask for miniaturization of the method of collecting the particles charged by corona discharge with the filter.A compact cavity 2 and a corona discharge portion 3 are provided on a flexible plastic substrate 1.The substrate 1 can be mounted on the face by rubber.Air is introduced into the corona discharge part 2 by taking the outside air in the small blister 2.The corona discharge section 3 comprises a ground electrode 5 opposed to the corona discharge electrode 4.The voltage required for the corona discharge is supplied from the high voltage power supply 6.The air passing through the corona discharge part 3 is supplied to the face 8 after passing through the electret filter 7.Since the floating particulates in the air passing through the corona discharge section 3 are charged, they are collected efficiently by the electret filter 7, and clean air is supplied to the face 8.Diagram
