Ultrasonic atomization sheet, electronic cigarette atomization core and atomizer

摘要

A piezoelectric ceramic body (10), wherein one surface of the piezoelectric ceramic body (10) is in contact with the positive electrode conductive layer (11) and the other surface of the piezoelectric ceramic body (10) is in contact with the negative electrode conductive layer (12) The layer (12) extends along the side of the piezoelectric ceramic body (10) to the surface of the piezoelectric ceramic body (10) where the positive electrode conductive layer (11) is located, and the positive electrode conductive layer 11) Disclosed are an ultrasonic atomization sheet (1), an atomization core of an electronic cigarette, and an atomizer, provided with a plurality of convex point areas (13) covering the edge of the surface of the piezoelectric ceramic body (10) Be done. Ultrasonic atomization sheet (1), electronic tobacco atomization core and atomizer are simple in construction, high in reliability of electrical connection, high in reliability of operation, high in atomization speed, and good in flavor of smoke In, the service life is long.
