摘要： A negative ion generator capable of easily producing a large amount of cluster ions having negative and positive ions mixed with each other and separating only negative ions for use, comprising a plurality of annular flow passages disposed parallel with each other and allowed to communicate with each other in circumferential direction so as to generate negative ions more effectively, mixed flow passages having a plurality of inlets and outlets formed in the annular flow passages so that the positions of inlets and outlets in the annular passages are displaced in circumferential direction and a plurality of communication flow passages allowing the inlets and the outlets formed in the different annular flow passages to communicate with each other, and fluid delivery and discharge flow passages allowed to communicate with the mixed flow passages, characterized in that a spray nozzle is connected to the delivery flow passage and a gas-liquid separator is connected to the discharge flow passage; a negative ion generating system, characterized in that the plurality of negative ion generators are connected to one system of air feed piping.
