Abstract

An ultrasonic electronic cigarette atomizer and electronic cigarette are disclosed. The atomizer includes an e-liquid storage assembly and an atomization core detachably connected to the e-liquid storage assembly. The atomization core includes an ultrasonic atomization sheet. The e-liquid storage assembly includes an e-liquid chamber and an e-liquid outlet for communicating an atomization surface of the ultrasonic atomization sheet with the e-liquid chamber. The e-liquid storage assembly further includes a moving assembly that can move in the direction of assembling/disassembling the atomization core to open/close the e-liquid outlet. When the atomization core is connected with the e-liquid storage assembly, the atomization core drives the moving assembly to move and open the e-liquid outlet. When the atomization core is disconnected from the e-liquid storage assembly, the moving assembly is reset and closes the e-liquid outlet.
