This application provides an elastic conductive element, an atomization
assembly and an
assembly method therefor, and an
ultrasonic atomizer. The atomization
assembly includes an
ultrasonic atomization sheet provided with a first
electrode and a second
electrode, where the
ultrasonic atomization sheet is used for ultrasonically atomizing a
liquid matrix to form liquid mist; and an elastic conductive element, which is in elastic contact with the
ultrasonic atomization sheet to support the ultrasonic atomization sheet, where one area of the elastic conductive element is directly or indirectly electrically connected to the first
electrode, and the other area of the elastic conductive element is directly or indirectly electrically connected to the second electrode, to form a loop among the first electrode, the elastic conductive element, and the second electrode. According to this application, energy stored by the ultrasonic atomization sheet after being powered on and then powered off is consumed and
vibration transmission of the ultrasonic atomization sheet is reduced through the elastic conductive element, so that a resistance board does not need to be additionally provided, thereby reducing parts and costs of the atomization assembly, and saving a structural space of the atomization assembly.
