Electronic atomization device and atomizer

The utility model relates to an electronic atomization device and an atomizer. The atomizer comprises an atomization cavity for heating aerosol to form a base body, an air outlet channel for outputting aerosol in the atomization cavity and a flow guide structure. The air outlet channel is provided with a first end and a second end in the axial direction. The second end and the first end are oppositely arranged, and the second end is arranged towards the atomization cavity; the diversion structure is arranged at the second end; a flow guide channel is formed between the flow guide structure and the end face of the second end and/or the inner side wall of the atomization cavity and used for guiding aerosol generated by the atomization cavity into the air outlet channel along the circumference of the flow guide structure. According to the atomizer, the flow guide structure is arranged at the second end of the air outlet channel, and the flow guide channel is formed between the flow guide structure and the end fa
