Disclosed is an electronic cigarette atomizer, comprising a liquid bin (6) and a vertically-installed ultrasonic atomization piece (42), wherein the liquid bin (6) is located above the ultrasonic atomization piece (42), a liquid guide channel (311) in communication with the liquid bin (6) is arranged below the liquid bin, a liquid outlet (331) is horizontally provided in the liquid guide channel (311), and the caliber of the liquid outlet (331) is smaller than that of the liquid guide channel (311); and a liquid guide cotton (43) is horizontally mounted across the ultrasonic atomization piece (42), the liquid guide cotton (43) makes contact with or is attached to an atomization face of the ultrasonic atomization piece (42), and the liquid outlet (331) abuts against the liquid guide cotton (43). For the electronic cigarette atomizer, when vaping, e-liquid is supplied in time, and e-liquid supply and ultrasonic atomization are balanced, such that the burning phenomenon can be prevented; and when not vaping, the liquid outlet is blocked by means of the viscosity of the e-liquid itself and the liquid guide cotton (43), such that the e-liquid is prevented from being continuously conducted by the liquid guide cotton (43), and the situation where an atomization cavity is soaked in the e-liquid and liquid leakage is consequently caused is avoided.
