Title: ULTRASONIC ATOMIZING SHEET, AND ELECTRONIC CIGARETTE ATOMIZING CORE AND ATOMIZER
Abstract:
Disclosed are an ultrasonic atomizing sheet, and an electronic cigarette atomizing core and atomizer. The ultrasonic atomizing sheet (1) comprises a piezoelectric ceramic body (10). One side of the piezoelectric ceramic body (10) is in contact with a positive conductive layer (11). The other side of the piezoelectric ceramic body (10) is in contact with a negative conductive layer (12). The negative conductive layer (12) extends along a side edge of the piezoelectric ceramic body (10) to a surface of the piezoelectric ceramic body (10) where the positive conductive layer (11) is located. A plurality of salient point areas (13), covering an edge of the surface of the piezoelectric ceramic body (10) where the positive conductive layer (11) is located, are provided on an edge of the negative conductive layer (12). The ultrasonic atomizing sheet (1), and the electronic cigarette atomizing core and atomizer have a simple structure, reliable electric connections, a reliable performance, fast atomizing speed, good smoke vapour taste and a long service life.
