An electronic cigarette atomizer employing a vertical ceramic atomizing unit, whICH comprises an outer tube (1), a liquid storage cup (2), a porous supporting sheet (3), a cigarette liquid permeation sheet (4), an atomizing seat (5), an atomizing unit (6), a sealed connection joint (7), and a power connector (8). the atomizing unit (6) includes a ceramic atomizing rod (61) made from a ceramic material, a heating wire (62) wound around the ceramic atomizing rod (61), and a lead wire (63) connected to both ends of the heating wire (62)； the ceramic atomizing rod (61) is vertically disposed in the atomizing seat (5), an upper-end surface of the ceramic atomizing rod (61) is in direct contact with the cigarette liquid permeation sheet (4) and can absorb and conduct electronic cigarette liquid from the cigarette liquid permeation sheet (4) to a portion around which the heating wire (62) is wound； the sealed connection joint (7) is in sealed connection with the atomizing seat (5) and the power connector (7), the inside of the sealed connection joint (7) is provided with a through hole (71) in an axial direction； the power connector (8) is inserted into a lower end of the outer tube (1). The electronic cigarette atomizer of the present invention employs a plurality of vertical ceramic atomizing units (6), which gives an atomization effect of a large smoke volume and avoids the production of a burnt odor due to the high-temperature burning of the atomizing seat. As a result, user experience can be significantly improved.
