Ultrasonic atomizer

An ultrasonic atomizer, comprising an e-liquid guide assembly (2), wherein the e-liquid guide assembly (2) comprises an e-liquid guide ceramic (21) in direct contact with e-liquid, e-liquid guide cotton (22) which is located below the e-liquid guide ceramic (21) and directly connected to the e-liquid guide ceramic (21), and a spring (23) which is located between the e-liquid guide ceramic (21) and the e-liquid guide cotton (22) and abuts the e-liquid guide cotton (22) against an atomization piece (322);

• the e-liquid guide ceramic (21) is a solid ceramic, and micropores which are used for conducting the e-liquid are integrally formed in the e-liquid guide ceramic (21);
• and
• the ultrasonic atomizer further comprises an e-liquid storage assembly (1) and an atomization assembly (3) connected to each other, wherein the atomization assembly (3) comprises an atomization head (32), and the atomization head (32) comprises an atomization sleeve (321) which is conductive and hollow;
• and the atomization piece (322) for ultrasonic atomization, an insulating seat (323) for supporting the atomization piece (322), and an electrode assembly (324) for electrically connecting the atomization piece (322) with an external power supply are sequentially arranged in an inner cavity of the atomization sleeve (321) from top to bottom.
