Temperature adjusting method and system applied to warmer

The invention provides a temperature adjusting method and system applied to a warmer, the method is applied to the temperature adjusting system of the warmer, and the temperature adjusting system comprises a control unit, a silicon controlled rectifier control switch circuit and a ceramic heater; the silicon controlled control switch circuit is connected with the control unit and the ceramic heater. The method comprises the steps that when the external temperature meets the preset temperature adjusting condition, a control signal corresponding to the external temperature is determined through a control unit, and the control signal is sent to a silicon controlled rectifier control switch circuit; the control signal is used for controlling the circuit connection state of the silicon-controlled control switch circuit; the silicon controlled rectifier control switch circuit converts the current circuit connection state into a circuit connection state corresponding to the control signal according to the control si
