Abstract

The utility model discloses a delousing driving circuit and a delousing comb. The delousing driving circuit comprises a power supply module, a driving module and a boosting module, wherein the driving module and the boosting module are arranged at the output end of the power supply module in parallel; the driving module provides a control signal for the boosting module; the boost module boosts input voltage and then transmits the input voltage to the buck module connected with the output end of the boost module. The boosted voltage is reduced by the step-down module, and then the reduced voltage is output by the output module electrically connected with the step-down module; the step-down module at least comprises a pressure-sensitive device R7, the output end of the pressure-sensitive device R7 is provided with a first pin of the output module in parallel and grounded, and a second pin of the output module is connected to the output end of the step-up module. The voltage-sensitive device is arranged at the output end of the boosting module, the boosted high voltage is reduced to be within the protection range of the voltage-sensitive device and then output, the output voltage precision is higher, it is guaranteed that the output module can effectively repel insects, meanwhile, electrical components in the circuit cannot be damaged, and the use safety of the circuit is improved.
