Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in figure 1, the safety device of the electric pressure cooker comprises a middle ring 1 of a cooker body assembly, wherein an annular groove 11 and a water chute 12 communicated with the annular groove are arranged on the middle ring.
A guide hole 121, a connecting seat 122 adjacent to the guide hole and a microswitch seat 123 are arranged at the water chute 12 of the middle ring 1;
also comprises a microswitch 2, a pressure spring 3, an active piece 4 and a base 5,
the driving member 4 comprises a driving part and a driven part 41, the driving part comprises a transverse seat 421, a rod 422 arranged on the transverse seat and a guide rod 423 arranged on the transverse seat; a driving block 411 is arranged on the driven part 41, and a driving inclined plane 412 is arranged at the lower end of the driving block 411;
a spring cavity 51 with an upper end opening and a side opening is arranged on the base 5, and a guide rod hole 52 is arranged on the bottom plate of the spring cavity 51;
the rod 322 of the active component passes through the guide hole 121 and extends into the water chute 12, and the transverse seat 421 is matched with the bottom plate of the water chute 12 for stopping; the base 5 is fixedly connected with the connecting seat 122, the pressure spring 3 is arranged in the spring cavity 51, and the guide rod 423 penetrates through the pressure spring 3 and the guide rod hole 52; the microswitch 2 is fixed on the microswitch seat 123, and the microswitch 2 is matched with the driven part 41;
