A discharge device is housed in a housing portion of a holder. The discharge device includes a housed section and a discharge electrode protruding from the housed section. The housed section is housed in the housing portion. The housed section includes a bottom wall and two side walls. The two side walls oppose each other in a longitudinal direction of the bottom wall. At least one of the two side walls is connected to the bottom wall via a curved surface. The curved surface guides a corner of the housing portion when the housed section is housed in the housing portion. As a result, the housed section is housed in the housing portion without catching on the corner.

An air stream controller and a system for static charge reduction comprising such air stream controller are disclosed. The air stream controller comprises an enclosed hollow body having a first surface and a second surface, wherein, an opening is on the first surface facing an incoming tubing of a device for static charge reduction for receiving air stream from the device for static charge reduction, wherein an outgoing tubing of the device for static charge reduction is attached onto the second surface of the enclosed hollow body for discharging the air stream. A technical solution to more effectively prevent the “leaking of air stream passage” can be achieved through the design of a multi-holes structure at the air passage to more broadly expand its air sucking area coverage without increasing the original suction power.

The invention provides a nano water ion group generator, including: at least a pair of P/N-type semiconductor dies including P-type semiconductor dies and N-type semiconductor dies, with one end being a cooling end and the other end being a heating end; a heat absorption member for obtaining a cold energy generated by the cooling end and transferring the cold energy to a blocking member; the blocking member for conducting the cold energy to obtain moisture in a condensed water or an air with high relative humidity; an ionizing member to absorb, collect or accumulate moisture in the condensed water or the air with high relative humidity, and be electrically coupled to the high voltage power supply for further ionizing the air and the moisture around the ionizing member under the action of avalanche effect to obtain at least one nanometer-sized substance among charged particles and oxygen-containing radicals.
