Air duct with negative ionization

Abstract

The application relates to the technical field of air ducts and discloses an air duct with negative ion ionization, which comprises a pipe body butting against an air outlet for discharging air into a room, the pipe body is provided with a pipe channel penetrating through the front and back of the pipe body, the two ends of the pipe body are provided with air inlet ports and air outlet ports, the middle part of the pipe channel is provided with an ionization section, and the pipe body is provided with an air ionizer; the air ionizer is provided with two ionization needles for high-voltage ionization of air; the ionization needles are respectively connected with ionization nets made of metal, the ionization nets are arranged along the cross-section direction of the pipe channel, the two ionization nets are arranged at intervals, and an ionization interval is formed. The air in the pipe channel is ionized through relative discharge of the two ionization needles, air negative ions are formed, the ionization area is increased through the ionization nets, and a large amount of air negative ions are formed in the ionization interval; the air blown out by the air outlet is effectively purified, and the air negative ions have the advantages of adsorbing dust, purifying air, improving heart and lung functions, promoting human metabolism, improving sleep quality and the like.
