1. An ultrasonic electronic cigarette atomizer comprising an ultrasonic atomization sheet (1), an atomization cotton (3), a liquid chamber (2), an air inlet tube (6), an air outlet channel (7), and a suction nozzle (8), wherein:
the atomization cotton (3) is communicated with the liquid chamber (2) and is in contact with an atomization surface of the ultrasonic atomization sheet (1);
an inlet of the air inlet tube (6) is communicated with the outside;
the air inlet tube (6), an atomization region of the ultrasonic atomization sheet (1), the air outlet channel (7), and the suction nozzle (8) are communicated in sequence;
an outlet of the air inlet tube (6) is opposite to the atomization region of the ultrasonic atomization sheet (1); and
an air inlet end of the air inlet tube (6) having an inner diameter larger than an inner diameter of an air outlet end of the air inlet tube (6);
the ultrasonic cigarette atomizer further comprising:
a cotton compression spring (5), wherein one end of the cotton compression spring (5) abuts against the atomization cotton (3) so that the atomization cotton (3) is in close contact with the ultrasonic atomization sheet (1); and an other end of the cotton compression spring (5) abuts against a boss (61) at an end of the air inlet tube (6); and
a mat layer (4) for preventing the atomization cotton (3) from being broken by oscillation.
