Novel spray hair straightener circuit

The invention relates to the technical field of hair straighteners, in particular to a novel spray hair straightener circuit which comprises a BUCK power supply used for presenting on and off states through a control signal of a modulation pulse so as to realize on and off of the circuit; the main controller is powered by the BUCK power supply and is used for generating a PWM (Pulse Width Modulation) signal according to a set control sequence and outputting the PWM signal to a subordinate module, and the subordinate module is a module directly or indirectly connected with the main controller; and the atomization driver is powered by the BUCK power supply and is used for receiving the PWM signal sent by the main controller so as to control an atomization sheet to work. The circuit is greatly simplified, the cost is greatly reduced, the output efficiency is improved due to the fact that full-bridge driving is added, an original 0.5 W master control power supply and a 7W atomization power supply are simplified i
