[0038] Working principle: The steam in the electric cooker can enter the exhaust valve body 1 through the vent pipe 2 and the backflow hole 16, enter the exhaust pipe 3 through the vent pipe 2, and finally be discharged through the gas outlet hole one 5. After entering the exhaust valve body 1 through the backflow hole 16, the steam is discharged through the two gas outlet holes two 6 on the fixed plate 4. When rapid pressure relief is needed, the sliding column 8 can be moved upward by pulling the pull plate 12 upward, realizing the upward movement of the sliding column 8, driving the pressure relief shell 7 to move upward, so that the top of the vent pipe 2 is communicated with the outside, and then the steam in the electric cooker is quickly discharged, achieving rapid pressure relief. The sliding column 8 drives the round plate 9 to extrude the strong spring 10 during upward movement, and the strong spring 10 plays a certain buffering role during steam discharge. When the pressure relief is completed, the pull plate 12 is released, and the pressure generated by the compression of the strong spring 10 drives the pressure relief shell 7 to move downward to restore the closure of the top of the vent pipe 2.

[0039] During the working process of the electric cooker, part of the water vapor and rice slurry enters the exhaust valve body 1, and most of the condensed water and rice slurry can be discharged back into the electric cooker by using the backflow hole 16. However, after long-term use, part of the rice slurry water stains will still remain in the exhaust valve body 1. At this time, the fan-shaped plate 15 can be rotated to open the exhaust valve body 1, and the inside of the fan-shaped plate 15 and the exhaust valve body 1 can be cleaned. After cleaning is completed, the convex plate 17 outside the fan-shaped plate 15 is turned into the annular groove 19 on the semi-ring block 18. During the turning-in process of the convex plate 17, the ball head rod 22 is extruded and moves into the circular groove 20 and extrudes the return spring 21. When the convex plate 17 is completely turned into the annular groove 19, the ball head rod 22 loses extrusion and moves outward by using the pressure generated by the compression of the return spring 21. Finally, the convex plate 17 is limited, ensuring the sealing between the fan-shaped plate 15, the semi-ring block 18 and the exhaust valve body 1.

[0040] Finally, it should be pointed out that the above-mentioned is only the preferred embodiment of the present application and is not used to limit the present application.
