摘要： Disclosed are an electronic cigarette atomization core (4) and atomizer. The electronic cigarette atomization core (4) includes an ultrasonic atomization piece (46) disposed horizontally, a liquid guide cotton (45) disposed above the ultrasonic atomization piece (46), and an electrode plate (47) placed on the liquid guide cotton (45). Each end of the electrode plate (47) is provided with a curved segment (472). The curved segment (472) includes a first contact (4721) located above a second contact (4722), wherein the first contact (4721) and the second contact (4722) are electrically connected but are distant horizontally, and the second contact (4722) abuts against an atomization surface electrode of the ultrasonic atomization piece (46) to form an electrical connection. A-middle part of the electrode plate (47) presses the liquid guide cotton (45) against the ultrasonic atomization piece (46) to form an atomization region, and the middle part of the electrode plate (47) is provided with a through hole (473) for exposing the atomization region. The electronic cigarette atomization core (4) and the atomizer ensure that the liquid guide cotton (45) well abuts against the atomization surface of the ultrasonic atomization piece (46) without any cotton pressing spring under the condition that an e-liquid atomization effect is not affected, and smoke generated by means of atomization and splashing c-liquid droplets are directly sprayed to an air outlet tube (3) without being shielded, thereby preventing a user from inhaling condensed e-liquid droplets and improving user experience.
