[0026] A reset mechanism for a circuit breaker leakage action, comprising a circuit breaker body 1, a circuit breaker switch 2 is arranged on the top of the circuit breaker body 1, a reset mechanism 3 is arranged on the outside of the circuit breaker body 1, a control main board 4 is arranged inside the circuit breaker body 1, and a leakage detection element 401, an alarm control element 402 and an audible and visual alarm module 403 are fixedly installed on the top of the control main board 4;

[0027] Specifically, the leakage detection element 401 is electrically connected to the control main board 4 through the guide piece, and the alarm control element 402 is electrically connected to the sound and light alarm module 403 through the guide piece. One end of the sound and light alarm module 403 is fitted through the left inner wall of the circuit breaker body 1 and extends to the outside thereof;

[0028] In this embodiment, the leakage detection element 401 is mainly used to monitor the leakage current, and the alarm control element 402 is mainly used to control the operation of the sound and light alarm module 403, thereby achieving the effect of alerting the user.

[0029] In this embodiment, please refer to Figure 1 and Figure 3 The reset mechanism 3 includes a protective shell 301 and a rotating shaft 302. The protective shell 301 and the rotating shaft 302 are both mounted on the left surface of the circuit breaker body 1, and a micro motor 303 is fixedly arranged on the left inner wall thereof, a main gear 304 is fixedly arranged on the output end of the micro motor 303, and a slave gear 305 and a guide rod 306 are fixedly sleeved on the outer surface of the rotating shaft 302, and a lever 307 is fixedly arranged on the right end of the guide rod 306;

[0030] Specifically, the rotating shaft 302 is rotatably connected to the left surface of the circuit breaker body 1 through a rotating member, the right surface of the protective shell 301 is fixed to the left surface of the circuit breaker body 1, and an arc groove is provided on its outer surface, and the main gear 304 is meshed and connected with the slave gear 305;

[0031] In this embodiment, the inner wall of the arc groove does not contact the outer surface of the guide rod 306, and the control main board 4 is electrically connected to the micro motor 303 through a wire. The type of micro motor 303 is a reciprocating motor. The setting of the micro motor 303 is mainly used to drive the main gear 304 and the slave gear 305 to engage and transmit.
