The piezoelectric ceramic negative oxygen ion generator comprises a negative ion generation module and a shell, the negative ion generation module comprises a PCB control board, a piezoelectric ceramic transformer and a negative ion output carbon brush, and the PCB control board comprises an MUC, an oscillating circuit, a driving circuit, a voltage doubling circuit and an energy feedback circuit. The invention belongs to the technical field of negative-ion generators, and particularly provides a negative-ion generator which adjusts PWM output frequency through direct-current high-voltage output voltage feedback detection, prevents human body electric shock risks, is constant in high-voltage end output power, has the advantages of being small in size, high in isolation voltage, safe and reliable, and is wider in applicability and more convenient to use. And the reliability and the stability of the piezoelectric ceramic negative oxygen ion generator are improved. 本发明公开了一种压电陶瓷负氧离子发生器，包括负离子发生模块和外壳，负离子发生模块包括PCB控制板
