1. A working control circuit for an ultrasonic atomizer, comprising:
a power module (1),
a booster circuit (2),
a smoking switch (3),
a controller (4),
a drive circuit (7), and
an LC oscillation circuit (5), wherein:
the power module (1) is electrically connected to the ultrasonic atomizer (J) sequentially through the booster circuit (2), the drive circuit (7), and the LC oscillation circuit (5);
the smoking switch (3) is electrically connected to an input end of the controller (4), and
an output end of the controller (4) is electrically connected to an enable end of the booster circuit (2);
it is characterized in that the working control circuit further comprises a voltage regulator circuit (6) for increasing a voltage value transmitted by the booster circuit (2) to the drive circuit (7) when a time interval between two adjacent ON moments of the smoking switch (3) is longer than a preset time,
an output end of the booster circuit (2) is electrically connected to an input end of the drive circuit (7) through the voltage regulator circuit (6), and
the output end of the controller (4) is electrically connected to a control end of the voltage regulator circuit (6).
