Atomization device

The invention is applicable to the technical field of medical instruments, and provides an atomization device, which comprises a device body, an atomization device and a control device, the atomizing cup is detachably arranged in the lower barrel body; the ultrasonic atomization assembly comprises an ultrasonic generator, an ultrasonic transducer and an ultrasonic film which are installed at the bottom of the atomization cup, and the ultrasonic generator is electrically connected with the ultrasonic transducer. The atomizing cup can be taken out from the opening in the bottom of the lower cylinder body, so that the atomizing cup is cleaned from the outside, atomized particles generated in the atomizing cup on the first supporting and releasing switching assembly form atomized gas, and the atomized gas can move upwards into the upper cylinder body through the flow guide channel. The compression atomization assembly further atomizes the atomized gas, large particles in the atomized gas are further decomposed an
