  • the inner ring is an electronic reinforcement ring 74 and the outer ring is an electronic control ring 75.
  • the electron enhancement ring 74 is capable of releasing electrons under the action of a varying electric field generated by the discharge end 73.
  • the electron reinforcement ring 74 is made of a suitable piezoelectric ceramic material, and a volume expansion is caused by the piezoelectric effect under the action of a varying electric field generated at the discharge end 73.
  • the peripheral electronic control ring 75 is made of a non-piezoelectric material whose shape is not affected by the electric field, and therefore, the peripheral electronic control ring 75 can prevent the expansion of the volume of the electron reinforcement ring 74.
  • the electronically controlled ring 75 is thereby applied to the pressure of the electron-enhancing ring 74 and combined with the action of the high electric field to cause the electron-enhancing ring 74 to release electrons.
  • the high electric field may be generated by voltage fluctuations at the discharge terminal 73 or by a pulse voltage at the discharge terminal 73.
  • the embodiment of the present invention increases the energy ring outside the discharge end, the high electric field generated by the discharge end is utilized to further release the energy ring outside the discharge end, thereby increasing the concentration of the negative ion and improving the negative ion air purifier. 70 work efficiency.
  • a negative ion air purifier formed by combining any two or more embodiments is also included in the patent protection scope of the present invention.
  • the present invention increases the concentration of negative ions in the air near the discharge end by adding an electron enhancement ring at the periphery of the discharge end, and releasing electrons under the action of a varying electric field generated at the discharge end, thereby effectively improving the operation of the negative ion air purifier. effectiveness.
