Ultrasonic electronic cigarette atomizer
Disclosed is an ultrasonic electronic cigarette atomizer. An atomizer shell, an atomization piece and a liquid guide structure are arranged in the atomizer. The liquid guide structure communicates with a liquid storage cavity in the atomizer shell. A heating body is further arranged in the atomizer shell. Both of the atomization piece and the heating body are in contact with the liquid guide structure, and both of the heating body and an atomization surface of the atomization piece communicate with an airflow passage, and a positive electrode and a negative electrode of the heating body are respectively connected with one end and the other end of a power supply. The heating body can not only quickly heat the tobacco tar to approach to its atomization temperature, but also can transfer a part of heat to the atomization piece, so that the atomization piece atomizes the tobacco tar quickly, shortening the atomization time.
