Electronic cigarette atomizer

An electronic cigarette atomizer comprising an ultrasonic atomizing plate (1). One surface of the ultrasonic atomizing plate (1) is in contact with an e-liquid storage plate (2). The e-liquid storage plate (2) is in communication with an e-liquid cavity (3). The e-liquid storage plate (2) is in communication with an airflow channel (4). The e-liquid storage plate (2) and the ultrasonic atomizing plate (1) are sequentially provided in the direction in which smoke is discharged. The electronic cigarette atomizer utilizes the oscillation of the ultrasonic atomizing plate (1) to produce smoke, solves the problem that heating with a heating wire is prone to burning, thus producing a burnt flavor, the high temperature produced by the heating wire is easily transmitted to the outer wall of an atomizer, resulting in an electronic cigarette becoming hot, low energy utilization rate, poor smoking mouthfeel, and the atomizer is prone to e-liquid leakage. The e-liquid storage plate (2) is in contact with the lower surface of the ultrasonic atomizing plate (1), smoke is discharged in the direction opposite to airflow, thus allowing large-particle smoke molecules to condense on the ultrasonic atomizing plate (1) or the e-liquid storage plate (2), preventing the large-particle smoke molecules from being inhaled by a user, and improving smoking mouthfeel.
