Abstract
An ultrasonic atomization type electronic cigarette includes an ultrasonic atomizer having an ultrasonic atomization sheet, an electronic cigarette housing, an upper cover assembly, and a locking structure. The angle α between the ultrasonic atomization sheet and the central axis of the electronic cigarette is 5° to 85°, preferably 15° to 55°. The housing is provided with an air inlet groove. A first support in the housing includes a receiving cavity for receiving the ultrasonic atomizer. The upper cover assembly may be used for opening the receiving cavity, and the locking structure may be used for locking the upper cover assembly. A liquid guide structure in the atomizer may include a liquid guide body in which a side of a first liquid guide layer is sandwiched between a side of a second liquid guide layer and an ultrasonic atomization surface.
