When the cover body 2 covers the cooking container 6 and the pressure between the cover plate 1 and the cooking container 6 is less than the preset pressure, the cover plate 1 and the cooking container 6 are in a sealing state; when the pressure between the cover plate 1 and the cooking container 6 is greater than or equal to the preset pressure, the cover plate 1 generates an upward movement trend under the action of the pressure and compresses the buffer member 7 to move towards the opposite direction of the cover closing, and the pressure is released through the gap between the cover plate 1 and the cooking container 6.

Wherein the preset pressure can be adjusted according to the cooking requirement. The preset pressure may be a pressure from the buffer 7 to the cap plate 1.

The state from the sealing state to the unsealing state between the cover plate 1 and the cooking bladder 6 includes the following cases: firstly, the cover plate 1 is in direct contact with the cooking container 6 for sealing, when the pressure between the cover plate 1 and the cooking container 6 is greater than or equal to the preset pressure, the cover plate 1 moves towards the direction far away from the cooking container 6 and generates a gap with the cooking container 6, and then the sealing is released for pressure relief; secondly, the cover plate 1 and the cooking container 6 are sealed through a sealing element, the cover plate 1 is connected with the sealing element, the cover plate 1 moves towards the direction far away from the cooking container 6 under the pressure of gas in the cooking container 6, when the cover plate 1 starts to move, the sealing element and the cooking container 6 are still in a sealing state, when the pressure between the cover plate 1 and the cooking container 6 is larger than or equal to the preset pressure, the cover plate 1 moves upwards for a set distance, a gap is formed between the sealing element and the cooking container 6, and the sealing is released to release pressure; thirdly, the cover plate 1 and the cooking container 6 are sealed through a sealing element, the cooking container 6 is connected with the sealing element, the cover plate 1 moves towards the direction far away from the cooking container 6 under the pressure of gas in the cooking container 6, when the cover plate 1 starts to move, the cover plate 1 and the sealing element are still in a contact sealing state, when the pressure between the cover plate 1 and the cooking container 6 is larger than or equal to the preset pressure, the cover plate 1 moves upwards for a set distance, a gap is formed between the sealing element and the cover plate 1, and the sealing is released to release pressure; fourthly, it is sealed through the sealing member between apron 1 and the culinary art courage 6, all be equipped with the sealing member on apron 1 and the culinary art courage 6, apron 1 and the culinary art courage 6 are sealed through the sealing member contact, when apron 1 begins to move, two sealing members still are in the contact seal state, when pressure is greater than or equal to the pressure of predetermineeing between apron 1 and the culinary art courage 6, apron 1 rebound settlement distance, produce the clearance between two sealing members, remove sealed the pressure release of carrying out.

The cover plate 1 and the cooking container 6 are in a sealed state, and it can be understood that the cover plate 1 and the pot rim of the cooking container 6 are in direct contact or in sealing element contact to form a seal.

The pressure relief principle adopted in the technology is as follows: the steam pressure in the closed space is increased to promote the cover plate 1 to move upwards, and the pressure steam is discharged through the gap between the cover plate 1 and the cooking liner 6. In order to avoid that the cover plate 1 moves up rapidly under the action of pressure, the cover body 2 is damaged, and high-pressure gas is discharged quickly to cause danger, the buffer piece 7 applies downward acting force to the upward moving cover plate 1 to slow down the moving speed of the cover plate 1 or shorten the moving distance of the cover plate 1 correspondingly, and the cooking appliance can perform pressure relief in the moving process of the cover plate 1; when the pressure in the cooking utensil is reduced to be less than the preset pressure, the buffer force of the buffer piece 7 inhibits the cover plate 1 from moving upwards, and the cover plate 1 falls down until the cover plate 1 covers the cooking container 6 again to form a closed space.

In the technical scheme, sealing and pressure relief are realized through compression and buffer adjustment of the buffer member 7 between the cover plate 1 and the cover body 2, a safety relief valve is not required to be arranged on the cover plate 1, and the structure of the cover plate 1 is simplified; the cover plate 1 is in direct contact with food in the cooking container 6, and the cover plate 1 without the safety relief valve is simple in structure and convenient to clean; in the culinary art process, food receives the pressure effect and splashes, and bolster 7 is located between apron 1 and the lid body 2, can not direct contact food, has solved the easy problem that blocks up of safety relief valve.
