Embodiment 1
[0032] The present invention proposes a kind of pressure cooker, can refer to Figure 2-Figure 4 , comprising a pot body 300 and a pot cover 400, the pot cover 400 is provided with an exhaust pipe 200 and a pressure limiting valve installed in cooperation with the exhaust pipe 200, the pressure limiting valve is a closed pressure limiting valve 500, the pressure limiting valve The valve 500 includes a valve body 3, the weight of the pressure limiting valve is 50-100 grams, the valve body 3 is formed with an exhaust chamber H with a lower end opening 1, and the exhaust pipe 200 extends into the exhaust chamber H, the top wall of the exhaust chamber H is provided with a valve core 4, the valve core 4 seals the exhaust port of the exhaust pipe 200, the side wall of the exhaust chamber H is provided with ribs, and the air flow of the exhaust pipe 200 is lifted The valve core 4 blows to the rib to drive the valve body 3 to rotate and exhaust, and the gap between the side wall of th...
Embodiment 2
[0039] The pressure limiting valve 600 of this embodiment can refer to Figure 5 In this embodiment, on the basis of the first embodiment, the upper end of the side wall of the exhaust chamber H is provided with a stepped portion 8 . That is, the stepped portion 8 is located at the joint between the side wall and the top wall of the exhaust chamber H. The upper end of the step portion 8 is in contact with the top wall of the exhaust chamber H, so that the step portion 8 can be easily manufactured out of the mold. Preferably, the exhaust port of the exhaust pipe 200 is lower than the step portion 8 , and since the valve core 4 seals the exhaust port of the exhaust pipe, the lowest point of the valve core 4 is lower than the step portion 8 . During high-pressure cooking, the gas in the exhaust pipe 200 is discharged after the valve core 4 is pushed up, and most of its initial direction is obliquely upward, and the step part 8 is just above the exhaust port, so the exhausted air...
