The gas in the pot enters the gap between the resistance part 33 and the inner wall of the valve cavity 11 through the first exhaust hole 12 and then enters the valve cavity 11, and finally is discharged from the second exhaust hole 21. The first air passage 333 is arranged on the first section 331, which can accelerate the flow of gas from the gap between the resistance part 33 and the inner wall of the valve cavity 11, reduce the risk of blockage, and improve the exhaust efficiency.

[0043] Further, the pressure cooker further comprises an exhaust button 5. The guide column 31 is connected with the exhaust button 5 after penetrating the second exhaust hole 21. When the pressure cooker needs to be depressurized, the exhaust button 5 is pressed to drive the float to move downward, so that the exhaust passage in the exhaust valve is opened, and the high-pressure gas in the pressure cooker can be quickly discharged.
