6. An ultrasonic nebulizer as claimed in any one of claims 1 to 5, wherein the ultrasonic atomizing assembly (11) further comprises a pressing member (117), and a part of the liquid guiding member (116) is pressed against the ultrasonic transducer plate (111) by the pressing member (117).

7. An ultrasonic nebulizer as claimed in claim 6, characterised in that the pressing element (117) abuts against the nebulizing body (15) at one end and against the ultrasonic transducer plate (111) via the liquid guide (116) at the other end.

8. An ultrasonic nebulizer as claimed in claim 7, wherein the liquid guide (116) comprises a first liquid guide portion (1161) in contact and liquid-guide connection with the ultrasonic transducer plate (111) and a second liquid guide portion (1162) in contact and liquid-guide connection with the liquid locking member (12);

the middle part of the first liquid guide part (1161) is pressed against the middle part of the ultrasonic transducer piece (111) through the pressing piece (117), a gap is formed between the periphery of the first liquid guide part (1161) and the periphery of the ultrasonic transducer piece (111), and the second liquid guide part (1162) is pressed at the bottom of the liquid locking piece (12) through the bottom wall of the liquid storage cavity (1525).

9. The ultrasonic atomizer according to any one of claims 1 to 5, wherein the atomizing body (15) comprises a housing (151) having an opening at one end, a base (153) fitted at the opening, and an atomizing seat (152) disposed in the housing (151), the atomizing seat (152) being mounted on the base (153) and defining the reservoir (1525).

10. An ultrasonic atomizing device, characterized by comprising an ultrasonic atomizer (1) according to any one of claims 1 to 9.
