The invention discloses a negative
ion generator provided with a carbon
fiber emitting end. The negative
ion generator comprises a negative
high voltage pulse excitation power supply, wherein the negative
high voltage pulse excitation power supply is connected with at least one emitting row; multiple carbon
fiber bundle emitting heads are arranged on the emitting row in rows; the multiple emitting heads re arranged on a basic strip; a nut is embedded in the basic strip; the basic strip is connected with a bottom box in a buckling manner; the
metal heads of the emitting heads adopt two-section structures; one carbon
fiber bundle is inserted into the hole of the front section of each
metal head and is fixed on the front section of the
metal head by
soldering; each metal head is fixed through a back section screw rod part; a
busbar board abutting on the far end of the screw rod part of each metal head is arranged in the bottom box; a part of a
copper-clad layer of the
busbar board on a substrate forms a detection line; the detection line is insulated from multiple emitting heads mutually; and when a switched-on
copper-clad part of each emitting head is provided with set
electric potential, inductive charges are formed on the detection line. The negative
ion generator has the beneficial effects of convenient replacement of the emitting heads of the emitting ends, firm
welding of the carbon fiber bundles, reliable
electrical connection, simple structure and good convenience in detaching without needing to set the detection line independently.
