Abstract
The utility model provides a toaster circuit, comprising an MCU control circuit, a rectification, filtering and voltage stabilizing circuit, a thermal coil assembly, an electromagnetic switch, and an electromagnet control circuit. One end of the electromagnetic switch is connected with an N line and an L line, and the other end of the electromagnetic switch is connected with the thermal coil assembly. One end of the electromagnet control circuit is connected with the electromagnetic switch. The toaster circuit is characterized by also comprising an active power-off device. The active power-off device comprises a heating device and one or more temperature fuses. The one or more temperature fuses are serially connected between an alternating current input end and the thermal coil assembly. The MCU control circuit comprises a time-delay circuit module. The time-delay circuit module is electrically connected with the heating device and is electrically connected with the electromagnet control circuit. According to the toaster circuit, when the electromagnet control circuit cannot control the normal disconnection of the electromagnetic switch with the toaster circuit, the active power-off device can cut off power, so as to guarantee the usage safety of a toaster.
