The atomizer 2 comprises an atomizing chamber (not shown) and an air outlet 20 communicated with the atomizing chamber, and the atomized aerosol of the atomizer 2 flows out from the air outlet 20. Under the state that the atomizer 2 is accommodated in the first accommodating cavity 11, the atomizer 2, the battery 5 and the airflow sensor 7 are respectively electrically connected with the controller 6, and the controller 6 controls the battery 5 to output working voltage to the atomizer 2 according to the detection information of the airflow sensor 7, so that the atomizer 2 works.

The heating assembly 9 is disposed outside the second accommodating chamber 12. The heating component 9 is one of a flexible circuit board, a thick film and a metal heating sheet.

In one embodiment, a rib 911 is formed on an inner surface of the second receiving cavity 12, and the seasoning component 3 can be fixed to the second receiving cavity 12 through the rib 911. Further, the rib 911 is a telescopic structure to control the flow rate of the aerosol flowing along the third flow direction 83. It will be appreciated that the inner surface of the second housing chamber 12 is formed with one or more ribs 911, and the number can be designed as required.

Further, the electronic atomizer further includes a memory (not shown) in which parameter information including a preset value of the flavoring element 3 to be smoked and a concentration of the flavoring material corresponding to the number of puffs are stored. The memory transmits the parameter information to the controller 6, and the controller 6 compares the pumping times detected by the airflow sensor 7 with the parameter information and controls the heating temperature of the heating unit 9 according to the comparison result. The controller 6 controls the temperature of the heating assembly 9 to be adjusted within the range of 10-380 ℃.
