The innovation points of the embodiment are as follows:

1) the knob cover on the left and right rotation panels 005 can be opened (fig. 26), closed (fig. 27) and pressure-adjusted (fig. 28), and one-key operation function can be realized.

2) The knob lid is rotated, and the pressure adjustment guide groove 0044 arranged in the knob lid continuously rotates under the state of closing the cover, so that the exhaust push rod 020 is driven to be separated from the steel ball 007, the steel ball 007 automatically blocks the first air hole 0231 of the lower piece 023 of the first air valve, and the pressure in the cooker is increased. When the pressure of the air in the pot reaches the set pressure value, the air valve visual rod 019 automatically ascends from the fifth mounting hole 0181 of the air valve cap 018, and the air pressure in the pot is exhausted from the second exhaust hole 0182 of the air valve cap 018. The air valve cap 018 is designed for air exhaust of an atmospheric hole and pressure visual exhaust, so that the problem of easy blockage in the cooking process is solved, and the air pressure prompt function is realized.

the working principle of the embodiment is as follows:

first, (as shown in fig. 29) the inside of the fixed seat 001 of the cover is designed with a concave-convex groove 0013, and two handfeel columns 002 installed in the turn button cover 004 bounce up and down under the elastic force of the tension spring 003, so that the turn button cover 004 has a vibration effect and makes a beep.

Secondly, (as shown in fig. 30) 2 oppositely opened cover opening and closing guide grooves 0043 and 1 pressure adjusting guide groove 0044 are designed in the turn button cover 004; one end of an exhaust push rod 020 is provided with a guide cylinder 0202; one end of the sliding block buckle 008 is provided with a toggle post 0081;

1) the 004 of the knob cover is rotated clockwise, and the exhaust push rod 020 clamped on the 004 of the knob cover moves towards the edge of the pan cover 010 under the action of the pressure adjusting guide groove 0044; make exhaust push rod 020 promote steel ball 007 and the first bleeder vent 0231 separation of first air valve lower part 023, realize the quick exhaust. At this time, the 004 of the rotating button cover continues to be rotated, the toggle post 0081 clamped on the slider button 008 in the 004 of the rotating button cover is driven by the opening and closing cover guide groove 0043 to make the slider button 008 open outwards, and the pot cover 010 can be separated from the pot. The 004 of the anticlockwise rotation knob cover can realize that the sliding block buckle 008 is folded, and the sliding block buckle can drive the exhaust push rod 020 to move towards the center of the cover when the sliding block buckle continuously rotates, so that the steel ball 007 is in sealing contact with the first air hole 0231 of the first air valve lower piece 023 automatically, and the pressure boosting in the cooker is realized.

2) when cooking, the slider button 008 can be folded by rotating the knob cover 004 anticlockwise, the steel ball 007 blocks the first air hole 0231 of the first air valve lower piece 023 to boost the pressure, when the pressure in the cooker reaches a set pressure value of 1-2.5 kPa, the air valve visual rod 019 automatically rises to warn that the pressure in the cooker exists and to discharge redundant air pressure in the cooker from the second air vent 0182 of the air valve cap 018. And the pressure in the cooker is stabilized within the set pressure value. When the pressure in the cooker is greater than an unexpected set value (3-4 kPa), the air pressure in the protection device can jack the steel ball 007 and discharge the air pressure from a gap between the steel ball 007 and the first air hole 0231 of the first air valve lower piece 023. If the unexpected air pressure continues to rise to 4.5-6 kPa, the sliding block buckle 008 deforms, so that the pot opening sealing ring 011 on the pot cover 010 overturns to exhaust air quickly, and accidents are avoided.

the above detailed description is specific to possible embodiments of the present invention, and the embodiments are not intended to limit the scope of the present invention, and all equivalent implementations or modifications that do not depart from the scope of the present invention are intended to be included within the scope of the present invention.
