As an improved structure of anion air purifier,It is used for anion air purifier for a period of time.Negative ion release effect will be reduced.And to improve the design,It is a shell seat provided with a negative ion emission end.A rotary lock is arranged outside the negative ion emitter.Tenon,All kinds of fastening methods, such as magnetic suction, are covered with a cover and a shell.In order to promote the consolidation of the two phases to form a negative ion air cleaner,And a negative ion releasing hole for negative ion emission is arranged near the negative ion emission end of the cover shell.Switch on the power supply of the negative ion air cleaner.It can promote the negative ion emission circuit in the shell seat to cause negative ion emission from the hair of the negative ion emission terminal.However, it is released from the hole of anion release.When the utility of dust adsorption on the periphery and inner edge of the anion releasing hole due to electrostatic factors or the utility of the anion emitting end is reduced,The cover shell can be removed quickly and conveniently.Then clean or replace the housing and the negative ion emitter.To maintain the utility of anion air purification.本創作為有關一種負離子空氣清淨器之改良構造，乃係針對負離子空氣清淨器使用一段時間後，負離子釋放效用會降低之問題，而加以改良設計，為在一設有負離子發射端頭之殼座體，於負離子發射端頭外以旋鎖，卡榫，磁吸....等各種扣接方式罩覆有一罩覆殼體，以促使兩相固結組成負離子空氣清淨器，且罩覆殼體鄰近負離子發射端頭處設有供負離子發射出之負離子釋放孔洞，藉開關啟動負離子空氣清淨器之電源，可促使殼座體內負離子發射電路致使負離子發射端頭發射負離子，而由負離子釋放孔洞釋放出，當負離子釋放孔洞周緣與內緣因靜電因素吸附灰塵或負離子發射端頭效用降低時，可以快速方便卸下罩覆殼體，進而加以清潔或更換罩覆殼體與負離子發射端頭，以維持負離子空氣清淨效用之實用便利創作者。
