The atomizer of claim 7, wherein the lock catch comprises a lock catch body and a shifting block, the shifting block is located at a side portion of the lock catch body, the shifting block and the lock catch body form an integral structure, and the lock catch body can be shifted to slide from the first working position to the second working position through the shifting block.

9. The atomizer of claim 8, wherein the lock body has a sliding connection hole formed therein, the sliding connection hole being an elongated hole, the size of the sliding connection hole in the lock sliding direction being greater than the size thereof in a direction perpendicular to the lock sliding direction;

a sliding connecting column is arranged on the inner wall of the rear cover of the machine body and is in sliding fit with the sliding connecting hole;

the machine body rear cover is also provided with a toggle hole, the toggle block penetrates through the toggle hole and extends out of the machine body rear cover, and the toggle block can slide in the toggle hole;

a stop block is further arranged on the inner wall of the rear cover of the machine body, and the second end of the elastic piece abuts against the stop block.

10. The atomizer of claim 8, wherein the first end of the lock body forms a locking end, the end of the rear cover forms a through hole, the bottom wall of the mounting groove of the cup forms a locking groove,

when the lock catch main body is located at the first working position, the locking end extends out of the through hole and extends into the locking groove, and when the lock catch main body is located at the second working position, the locking end contracts into the through hole.

11. A method for controlling an atomizer according to any one of claims 1 to 10, wherein said method comprises an automatic mode, said automatic mode comprising:

starting the automatic mode;

the detection value of the air pressure detection device is obtained,

when the detection value is larger than or equal to a preset air pressure value, controlling the atomizer to start;

and continuously acquiring a detection value of the air pressure detection device, and controlling the vibration frequency of the atomization sheet according to the detection value.

12. The control method of claim 11, further comprising a manual mode comprising:

controlling the atomizer to start;

and continuously acquiring a detection value of the air pressure detection device, and controlling the vibration frequency of the atomization sheet according to the detection value.
