[0035] When the utility model is in use, the gas inside the pot body 1 enters the valve seat 502 from the vent hole 509, and then drives the exhaust fan 506 to rotate, speeding up the exhaust flow rate, and finally discharges from the exhaust hole 508 on the protective cover 507. The rotation of the exhaust fan 506 will drive the mounting ring 505 and the rotating ring 504 to rotate on the fixing ring 503. When the valve seat 502 needs to be removed from the pot cover 2, it is only necessary to rotate the rotating block 804 on the protective cover 507. The rotating block 804 rotates and no longer interferes with the sliding rod 802. The third spring 803 is reset to push the sliding rod 802 out. After the sliding rod 802 is pushed out, the operator can hold the sliding rod 802 to rotate the protective cover 507 and the fixing cylinder 801, thereby driving the valve seat 502 to rotate.

At this time, the mounting ring 505 and the exhaust fan 506 can be pulled off the rotating ring 504, and then the exhaust fan 506 is disassembled. The setting of the limit ring 607 effectively prevents the excessive sliding of the sliding ring 606 from causing inconvenience in resetting. The setting of the guide column 608 improves the sliding stability of the sliding ring 606. The setting of the guide rod 603 effectively prevents the second spring 604 from When in use, push the two shifting blocks 402 on the pot ears 3 with both hands, the shifting blocks 402 drive the plugging plate 401 to slide, the first spring 404 contracts, and then the pot cover 2 is buckled on the pot body 1, and then the shifting blocks 402 are released, the first spring 404 is reset and drives the plugging plate 401 to press the pot cover 2, the setting of the guide strip 403 improves the sliding stability of the plugging plate 401, and avoids the deviation of the first spring 404, and the setting of the buckle groove 405 makes it convenient to take the pot body 1 through the pot ears 3.
